Risks and uncertainties we face are set forth in this Annual Report on Form 10-K in greater detail under the heading “Risk Factors.” The following is a summary of the principal risk factors:

SCYNEXIS, Inc. is pioneering innovative medicines to overcome and prevent difficult-to-treat and drug-resistant infections. We are developing our proprietary antifungal platform “fungerps”, a novel class of antifungal agents called triterpenoids, that are structurally distinct glucan synthase inhibitors and have generally shown in vitro and in vivo activity against a broad range of human fungal pathogens such as Candida and Aspergillus genera, including multidrug-resistant strains, as well as Pneumocystis, Coccidioides, Histoplasma and Blastomyces genera and most common mucorales species.

Ibrexafungerp is the first representative of this novel class of antifungals with additional assets from the “fungerp” family, including SCY-247, in preclinical stages of development. In June 2021 and December 2022, we announced that the United States (U.S.) Food and Drug Administration (FDA) approved BREXAFEMME (ibrexafungerp tablets) for treatment of patients with vulvovaginal candidiasis (VVC), also known as vaginal yeast infection, and for the reduction in the incidence of recurrent vulvovaginal candidiasis (RVVC), respectively. Oral ibrexafungerp is also under development for other systemic fungal diseases.

SCY-247, a second-generation antifungal compound from this novel class, is in preclinical development stage. We anticipate initiating a Phase 1 study for SCY-247 in the second half of 2024.

The FDA has granted Qualified Infectious Disease Product (QIDP) and Fast Track designations to ibrexafungerp for the indications of VVC (including the prevention of recurrent VVC), invasive candidiasis (IC) (including candidemia), and invasive aspergillosis (IA), and has granted Orphan Drug designations for the IC and IA indications. The European Medicines Agency has granted Orphan Medicinal Product designation to ibrexafungerp for IC. We anticipate that the FDA may grant QIDP and Fast Track designations for the IV and oral formulations of SCY-247. These designations may provide us with additional market exclusivity and expedited regulatory paths.

On March 30, 2023, we entered into a license agreement (the GSK License Agreement) with GSK. Pursuant to the terms of the GSK License Agreement, we granted GSK an exclusive (even as to us and our affiliates), royalty-bearing, sublicensable license for the development, manufacture, and commercialization of ibrexafungerp, including the approved product BREXAFEMME, for all indications, in all countries other than those in the Greater China region and certain other countries already licensed to third parties (the GSK Territory). The parties closed the transactions contemplated by the GSK License Agreement in May 2023 and we received an upfront payment of $90.0 million. In June 2023, we announced the achievement of a $25.0 million performance-based development milestone under the GSK License Agreement. This milestone payment followed a development goal for the Phase 3 MARIO study for ibrexafungerp in IC as we continued executing ongoing ibrexafungerp trials.

On December 26, 2023, we and GSK entered into a binding memorandum of understanding (Binding MOU) for amendment to the GSK License Agreement. The GSK License Agreement was amended in connection with the delay in the commercialization of BREXAFEMME (see "Product Recall and Clinical Hold" below) and further clinical development of ibrexafungerp associated with this event. Under the terms of the updated GSK License Agreement, as amended by the Binding MOU, we are eligible to receive potential:

upon achievement of multiple sales thresholds between $300 million and $500 million; and $35 / $35 / $30 million to be paid at each sales threshold of $750 million and $1 billion.

We will continue to be responsible for the execution and costs of the ongoing clinical studies of ibrexafungerp but will have the potential to receive up to $72.35 million in development milestones (revised from up to $75.5 million as provided in the GSK License Agreement), which comprise: $25 million already paid; $10 million for the delivery to GSK of final clinical study reports for the completed FURI, CARES, and NATURE clinical studies; up to $30 million for the achievement of two interim milestones associated with our resumption and continued performance of the MARIO Study after the clinical hold is lifted; and $7.35 million for the successful completion of the MARIO Study.

In the case of each of the above milestones, such milestone events are defined in the GSK License Agreement, as amended by the Binding MOU. GSK will also pay royalties based on cumulative annual sales to us in the mid-single digit to mid-teen range. The royalty terms are not amended by the Binding MOU.

Following a review by GSK of the manufacturing process and equipment at the vendor that manufactures the ibrexafungerp drug substance, we became aware that a non-antibacterial beta-lactam drug substance was manufactured using equipment common to the manufacturing process for ibrexafungerp. Current FDA draft guidance recommends segregating the manufacture of non-antibacterial beta-lactam compounds from other compounds since beta-lactam compounds have the potential to act as sensitizing agents that may trigger hypersensitivity or an allergic reaction in some people. In the absence of the recommended segregation, there is a risk of cross contamination. It is not known whether any ibrexafungerp has been contaminated with a beta-lactam compound and we have not received any reports of adverse events due to the possible beta-lactam cross contamination. Nonetheless, out of an abundance of caution and in line with GSK’s recommendation, we have recalled BREXAFEMME® (ibrexafungerp tablets) from the market and placed a temporary hold on clinical studies of ibrexafungerp, including the Phase 3 MARIO study.

The patient-level and clinical product recall has been initiated and we are working with an experienced vendor to manage the process. In September 2023, after we have announced our voluntary clinical hold, the FDA concurred with our voluntary hold and placed a clinical hold. We are working with the FDA to discuss paths for resolution of this issue. The clinical hold and recall affected two ongoing clinical studies: the Phase 3 MARIO study and a Phase 1 lactation study. The clinical hold does not impact the recently completed FURI, CARES, VANQUISH and SCYNERGIA clinical studies, for which dosing is complete. The NATURE study, which is an observational study in patients with IC treated with standard of care antifungals (not ibrexafungerp), is also not affected by this hold. The FDA determined that the compassionate use program for ibrexafungerp, which provides ibrexafungerp to patients with limited or no other treatment options, can continue provided the patient’s treating physician concludes a favorable benefit-risk assessment and the patient is made aware of and consents to the risk. This applies to patients currently in the program as well as for new patients, pending confirmation of available supply. Our preclinical stage compound, SCY-247, is not affected by these developments.

In response to the hold on clinical studies of ibrexafungerp by the FDA due to possible beta-lactam cross contamination, we have entered into certain new manufacturing agreements with third-party contract manufacturers to begin producing new batches of ibrexafungerp which we believe will allow us to lift the clinical hold and restart our impacted clinical studies, the Phase 3 MARIO study and a Phase 1 lactation study.

We, Hercules Capital, Inc. (Hercules Capital) and Silicon Valley Bridge Bank, N.A. (as successor to Silicon Valley Bank) (SVBB) were parties to a Loan and Security Agreement dated as of May 13, 2021 (the Loan Agreement), pursuant to which Hercules Capital, SVBB and each of the other lenders from time-to-time party to the Loan Agreement (collectively, the Lenders) loaned to us $35 million. In connection with the entering into of the GSK License Agreement, we entered into a First Amendment and Consent to Loan and Security Agreement (the First Amendment) with the Lenders pursuant to which the Lenders consented to us entering into the GSK License Agreement and we agreed to pay to the Lenders an amount equal to the sum of (i) all outstanding principal plus all accrued and unpaid interest with respect to the amounts loaned under the Loan Agreement (approximately $35.4 million), (ii) the prepayment fee payable under Loan Agreement ($262,500), (iii) the final payment payable under Loan Agreement ($1,382,500), and (iv) all other sums, if any, that shall have become due and payable with respect to loan advances under the Loan Agreement. These payments became due upon the earliest of (A) one business day following receipt by us of the $90 million upfront payment payable to us under the GSK License Agreement, (B) June 1, 2023, or (C) the termination of the GSK License Agreement.

Following the closing of the transactions under the GSK License Agreement, in May 2023, we received an upfront payment pursuant to the terms of the GSK License Agreement, which triggered our obligation to repay the amounts due under the terms of the First Amendment. In connection with the repayment of those amounts due, in May 2023, we and the Lenders

executed a payoff letter confirming the amounts due under the First Amendment, and our confirmation that the Loan Agreement, as amended by the First Amendment, was terminated.

On November 7, 2023, a securities class action was filed by Brian Feldman against us and certain of our executives in the United States District Court, District of New Jersey, alleging that, during the period from March 31, 2023 to September 22, 2023, we made materially false and/or misleading statements, as well as failed to disclose material adverse facts about our business, operations, and prospects, alleging specifically that we failed to disclose to investors: (1) that the equipment used to manufacture ibrexafungerp was also used to manufacture a non-antibacterial beta-lactam drug substance, presenting a risk of cross-contamination; (2) that we did not have effective internal controls and procedures, as well as adequate internal oversight policies to ensure that its vendor complied with current Good Manufacturing Practices (cGMP); (3) that, due to the substantial risk of cross-contamination, we were reasonably likely to recall its ibrexafungerp tablets and halt its clinical studies; and (4) as a result of the foregoing, our statements about our business, operations, and prospects were materially misleading and/or lacked a reasonable basis. The complaint seeks unspecified damages, interest, fees and costs on behalf of all persons and entities who purchased and/or acquired shares of our common stock between March 31, 2023 to September 22, 2023. We disagree with the allegations and intend to defend the litigation vigorously.

SCY-247 is a second-generation antifungal compound, from a novel class of structurally-distinct glucan synthase inhibitors, triterpenoids (fungerps), that are under development as therapeutic options for systemic fungal diseases. The triterpenoid class of antifungals represents the first new class of antifungal compounds since 2001. These agents combine the well-established activity of glucan synthase inhibitors with the potential flexibility of having oral and IV formulations. SCY-247 is in preclinical development stage and has demonstrated broad-spectrum antifungal activity, in vitro and in vivo. We anticipate that the FDA may grant QIDP and Fast Track designations for the IV and oral formulations of SCY-247.

We continue to progress the development activities for SCY-247. Some of these activities, including assessing the activity of the compound against Candida auris and Mucorales are being supported by NIH grants. We anticipate initiating a Phase 1 study for SCY-247 in the second half of 2024.

Mucormycosis is a life-threatening fungal infection with an associated mortality that ranges from 46% to 96%, most commonly affecting immunocompromised patients including those with leukemia, patients undergoing bone marrow transplants, and patients affected by severe COVID or uncontrolled diabetes mellitus. In a highly lethal mouse model of mucormycosis, SCY-247 showed very promising in vivo efficacy. Orally administered SCY-247 resulted in 40% and 50% survival at 21 days post infection for the intermediate (32 mg/kg) and high doses (48 mg/kg), respectively, compared to 0% survival in the placebo group (p = 0.011 and 0.007, respectively). This is comparable to the 40% survival observed in the control group treated with 10 mg/kg of intravenous standard of care of liposomal amphotericin B (LAMB) (p = 0.008 vs. placebo). Even more encouraging was a 90% survival observed in the group receiving combination therapy of SCY-247 32 mg/kg plus LAMB 10 mg/kg (p < 0.0001 vs. placebo and p < 0.05 vs. monotherapy). The positive survival data correlated with a statistically significant fungal burden reduction in both lung and brain tissue with SCY-247 32 mg/kg dose (p = 0.0288 and 0.0355 vs. placebo, respectively) and 48 mg/kg dose (p = 0.0015 and 0.0052 vs. placebo, respectively) as well as with the active control LAMB (p = 0.0005 vs. placebo for both lung and brain tissues). The combination treatment of SCY-247 plus LAMB demonstrated the greatest reduction in fungal burden and was highly statistically significant in both lung and brain tissue (both p < 0.0001 vs. placebo).

The ibrexafungerp indications below summarize the status of the indications for ibrexafungerp being developed in the hospital and community settings by us under the GSK License Agreement. We will continue to be responsible for the execution and costs of these clinical studies of ibrexafungerp.

Enrollment is on clinical hold in our prospective, randomized, double-blind, global Phase 3 study to evaluate the efficacy, safety and tolerability of oral ibrexafungerp as a step-down therapy for patients with IC including candidemia following IV echinocandin therapy in the hospital compared to currently available therapies (the MARIO study). Eligible patients with IC will receive treatment with IV echinocandin and will then be switched to either oral ibrexafungerp or a standard of care option, either oral fluconazole or best available therapy (BAT) for subjects with infections caused by fluconazole non-susceptible strains, once step-down criteria are met. If enrollment resumes, approximately 220 patients will be enrolled and randomized in the study.

care. The primary end point of the study will be all-cause mortality at 30 days after initiation of antifungal therapy. The data from the MARIO study is intended to be supportive of an NDA submission for ibrexafungerp as step-down therapy in patients with IC. Such submission would be made by GSK and any resulting approval would be held by GSK.

We enrolled 233 patients in our Phase 3 FURI study investigating the potential of ibrexafungerp as a treatment for fungal infections that are refractory or intolerant to other antifungals and we anticipate providing topline data to GSK in the first half of 2024. We also achieved a target enrollment of 30 patients in our Phase 3 CARES study, focused on patients with infections caused by C. auris. Topline data from the CARES study is positive and consistent with previously disclosed results from interim analyses. It is anticipated that the data will be presented at a future scientific meeting. The data from these studies is intended to be supportive of an NDA submission for ibrexafungerp as salvage therapy in patients with certain refractory invasive fungal diseases. Such NDA submission would be made by GSK and any resulting approval would be held by GSK.

Based on promising preclinical data from combination use of ibrexafungerp with voriconazole, the current standard of care, vs. Aspergillus spp., a Phase 2 study (SCYNERGIA study) of oral ibrexafungerp in combination with voriconazole in patients with IA was conducted. This study is a randomized, double-blind trial with the objective of assessing the safety and efficacy of oral ibrexafungerp in combination with voriconazole, compared to voriconazole alone. We completed enrollment with 22 patients included and the data analysis is ongoing. We anticipate providing topline data for the SCYNERGIA study to GSK in the first half of 2024.

We have completed the enrollment of the VANQUISH Phase 3b open-label trial (VANQUISH study) evaluating the safety and efficacy of ibrexafungerp in patients with complicated vulvovaginal candidiasis who failed to respond to treatment with fluconazole. The VANQUISH study enrolled 150 complicated VVC patients who received 600 mg of oral ibrexafungerp for one, three or seven consecutive days determined by their underlying complicating condition, including immunocompromised state. Complicated patients include patients with recurrent VVC, those with VVC caused by non-albicans Candida species and those with diabetes, immunocompromising conditions (e.g., HIV), or immunosuppressive therapy (e.g., corticosteroids). We anticipate providing topline data for the VANQUISH study to GSK in the first half of 2024.

Ibrexafungerp, the first agent in a novel antifungal class, acts through the inhibition of the glucan synthase complex, an established target in antifungal therapeutics. Ibrexafungerp is being developed as oral and IV formulations and has demonstrated potent activity against a large collection of medically relevant strains of Candida and Aspergillus genera, including multidrug-resistant strains, as well as Pneumocystis, Coccidioides, Histoplasma and Blastomyces genera. Additionally, ibrexafungerp has shown in vitro, in vivo and clinical activity against multidrug-resistant organisms such as

Candida auris and synergistic/additive activity in combination with isavuconazole against Aspergillus strains and in combination with amphotericin B against fungi causing mucormycosis. Ibrexafungerp has unique attributes that define its potential to address significant unmet medical needs and provide considerable commercial opportunities, including:

We believe that ibrexafungerp, if approved, has the potential to address significant gaps with commercially available therapies in the following indications:

In the future, we or our licensee GSK, may also consider other indications for ibrexafungerp for which longer oral antifungal regimens are typically needed and would benefit from the broad-spectrum activity, favorable safety profile and low potential for drug-drug interactions, including for the treatment of chronic fungal infections and for prophylaxis.

For the treatment of invasive fungal infections, we expect that prescribing physicians will be located at major medical centers, where physicians specializing in critical care, infectious disease specialists, and physicians treating immune compromised or immuno-suppressed patients, such as oncologists and those performing solid organ transplants and stem cell transplants, are likely to be found.

VVC, commonly known as a vaginal yeast infection due to Candida, is the second most common cause of vaginitis. Although these infections are frequently caused by Candida albicans, infections caused by fluconazole-resistant and non-albicans Candida strains, such as Candida glabrata, have been reported to be on the rise. An estimated 70-75% of women worldwide will have at least one episode of VVC in their lifetime, and 40-50% of them will experience multiple episodes. VVC can be associated with substantial morbidity, including significant genital discomfort (pain, itching, burning), reduced sexual pleasure and activity, psychological distress (stress, depression, anxiety), embarrassment, reduced physical activity, and loss of productivity. Typical VVC symptoms include pruritus, vaginal soreness, irritation, excoriation of vaginal mucosa and abnormal vaginal discharge.

Current treatments for VVC include several topical azole antifungals and oral fluconazole, which is the only (other than BREXAFEMME) orally administered antifungal currently approved for the treatment of VVC in the U.S. and which accounts for over 90% of the prescriptions for VVC written each year, primarily by obstetrician and gynecologist (OGBYN) offices. Fluconazole reported a 55% therapeutic cure rate in its label, which now also includes warnings of potential fetal harm, illustrating the need for new oral alternatives. In addition, there are many women with persistent (chronic) infections, recurrent infections (four or more recurrences in a 12-month period), non-albicans / azole-resistant Candida strains (e.g., Candida glabrata), diabetic patients, especially with poorly controlled glycemia, and obese patients that could potentially benefit from a non-azole treatment. Except for BREXAFEMME, there are only azole class treatments available for women suffering from VVC with no other approved alternative class in the U.S. When a patient fails fluconazole therapy, patients typically are treated with more fluconazole or a topical azole. Women with VVC could benefit from a non-azole, and preferably oral, treatment option.

We believe BREXAFEMME has the potential to address vaginal yeast infections across a broad range of patients and could be an ideal treatment option for many patients for whom current treatment options are suboptimal. Despite yeast

infections being so common and prevalent, with millions of women suffering from them every year, it is still an under-appreciated, under-reported, and under-served women’s health condition. Treatments for VVC have historically included several topical azole antifungals and oral fluconazole. Approximately 80% of VVC sufferers will have more than one yeast infection and over a third of women may have six yeast infections or more in a lifetime. There are over 17 million prescriptions written for VVC in the U.S. annually, all of which (prior to BREXAFEMME) belonged to a single drug class, the azoles. There had been no new oral treatment for VVC in over 25 years other than BREXAFEMME, and we believe health care providers are eager for a novel oral alternative to treat their patients.

BREXAFEMME is the first and only approved oral, non-azole treatment for vaginal yeast infections. We believe that BREXAFEMME’s unique combination of features, including being from a novel class with a different mechanism of action, single-day oral dosing, broad spectrum, and fungicidal activity in all Candida species (albicans and non-albicans) including fluconazole-resistant strains, differentiates it from competing products.

Treatment options for invasive candidiasis are limited to three main drug classes: echinocandins, azoles, and amphotericin B. The echinocandins are considered the first line recommended therapy in most invasive candidiasis settings. Because the echinocandins can be administered only intravenously, orally administered azoles are often used as step-down agents after initial IV echinocandin therapy. However, antifungal treatment duration for invasive candidiasis typically extends for several weeks and patients for whom the azoles are not a suitable therapy due to resistance, intolerance, or risk of drug-to-drug interaction are restricted to use IV therapy for several weeks. Amphotericin B is also only available via IV administration and is associated with a significant risk of renal toxicity and infusion reactions, making it an unsuitable option in settings where there is underlying, or high risk of, renal impairment. Due to significant monitoring issues, Amphotericin B is also less desirable for outpatient parenteral administration. The echinocandins are typically well tolerated but clinical resistance is rising in many centers, due to development of mutations in the fks genes leading to echinocandin resistance and shift species with natural resistance as well as the rise of novel drug resistant species, such as Candida auris. When resistance develops, the available treatment options may be less efficacious or more toxic. The phenomenon of multi-drug resistance is also reported among isolates of different species of Candida, making the management of patients suffering from these infections extraordinarily challenging, considering the very limited treatment options available. Specifically, 90% of Candida auris isolates have been reported to be resistant to at least one antifungal agent and 30% of isolates resistant to at least two antifungals.

There is a clear need for new antifungal treatment options for patients with invasive candidiasis that are refractory or intolerant to available therapies as well as for those who would benefit from oral therapy. We believe ibrexafungerp has the potential to address many of these unmet needs by providing a well-tolerated oral antifungal agent, with low risk for drug-drug interactions that has activity against azole-resistant and most echinocandin-resistant strains.

Current treatment guidelines for IA in the U.S. and in Europe recommend the use of azoles (itraconazole, voriconazole or isavuconazole) as the initial first-line therapy. However, patients face unsatisfactory clinical outcomes with mortality rates ranging from 30% to 80% (depending on the stage of infection and the host underlying disease) and long treatment durations. Additionally, current azole therapies often exhibit drug-drug interactions, and the recent emergence of A. fumigatus azole-resistance is increasingly becoming of clinical concern worldwide.

Due to the significant rate of resistance in some countries, combination antifungal therapy as first-line treatment for patients suspected of IA is recommended. The combination of voriconazole or isavuconazole with a glucan synthesis inhibitor agent (IV echinocandin) is recommended at least until results of resistance testing are obtained. A previous study, by Marr et al. in IA patients demonstrated that the combination of an IV echinocandin and an IV/oral azole for two weeks followed by an oral azole alone for four additional weeks improved outcomes in certain patient subgroups. In this study, the combination regimen was given for only two weeks because of the limitations of using an IV echinocandin long-term in the outpatient setting. We believe that oral ibrexafungerp, if approved in combination with standard of care for the treatment of IA, would allow patients to receive the desired combination treatment of two agents with different mechanisms of action for the full six to twelve weeks of therapy, potentially leading to better outcomes.

Our competitors include large pharmaceutical and biotechnology companies, and specialty pharmaceutical and generic drug companies. The leading antifungal drugs representing each main class are as follows:

Azoles. Noxafil® (posaconazole) marketed by Merck and Cresemba® (isavuconazole), approved in the U.S. and other global markets and marketed by Astellas in the U.S.; Diflucan® (fluconazole), Pfizer, off-patent with multiple generics, Terazol (terconazole), Jannsen, off-patent with multiple generics, Gynazole (butoconazole), Perrigo, off patent with multiple generics;

Echinocandins. Cancidas® (caspofungin), a product that became generic in March 2017, and Mycamine® (micafungin), a generic product. Pfizer markets the echinocandin Eraxis® (anidulafungin); and

Polyenes. AmBisome® (liposomal amphotericin B), a product sold by Gilead in Europe, by Astellas in the U.S. and by Dainippon-Sumitomo in Japan.

Pfizer, Merck, Astellas, and Gilead are all large pharmaceutical companies with significant experience and financial resources in the marketing and sale of specialty pharmaceuticals. Various other producers market and sell generic oral voriconazole, fluconazole and itraconazole.

The VVC market has three generic prescription agents, fluconazole (oral), terconazole and butoconazole (topical), manufactured by multiple generic companies. There is limited to no marketing to support these generic products. In 2022, oral oteseconazole (brand name Vivjoa), developed and marketed by Mycovia Pharmaceuticals, Inc., was approved for the reduction in the incidence of recurrent vulvovaginal candidiasis in women who are not of reproductive potential. Recently, in March 2023, the long-acting IV echinocandin Rezafungin (brand name Rezzayo) being developed by Cidara Therapeutics, Inc.and marketed by Melinta Therapeutics, was approved for the treatment of candidemia and invasive candidiasis in adults with limited or no alternative treatment options. Other antifungals in development include Fosmanogepix (APX-001) being developed by Amplyx Pharmaceuticals Inc., the polyene amphotericin B oral formulation MAT2203 being developed by Matinas BioPharma Holdings Inc., and Olorofim (F901318) being developed by F2G Limited. These companies may have greater resources than ours.

We believe that ibrexafungerp has the ability to perform well in the future fungal infection market given the limited competitive marketplace, the unmet medical need, and the often high mortality rate of many of these infections. The key competitive factors affecting the success of ibrexafungerp, if approved, are likely to be its efficacy, safety, convenience, use in outpatient settings, the level of generic competition and the availability of reimbursement from government and other third-party payors. If approved, we believe that ibrexafungerp’s unique features, including being from a novel antifungal class, broad-spectrum of activity including resistant strains, IV and oral formulations, fungicidal activity versus Candida, high tissue penetration, and favorable safety profile, will differentiate it from competing products and allow premium pricing to generics and other competing products.

The commercial opportunity for ibrexafungerp could be reduced or eliminated if competitors develop and commercialize products that are safer, more effective, have fewer or less severe side effects, are more convenient or are less expensive than products that we or GSK may develop. Competitors also may obtain FDA, or other regulatory, approval for their products more rapidly than we or GSK obtains approval for our ibrexafungerp products. In addition, the commercial success of ibrexafungerp may be affected because in many cases insurers or other third-party payors seek to encourage the use of generic products. In the azole class, fluconazole, itraconazole, posaconazole, and oral voriconazole are generic. Caspofungin, the largest selling echinocandin, is now available on a generic basis. If approved, we believe ibrexafungerp will be capable of delivering value supportive of premium pricing over competitive generic products.

Ibrexafungerp is a semi-synthetic compound that involves fermentation and synthetic chemical steps in its manufacturing process. The synthetic process does not require any specialized equipment and uses readily sourced intermediates. We do not own or operate and do not intend to own or operate facilities for manufacturing, storage and distribution, or testing of drug substance or drug product. We have relied on third-party contract manufacturers for synthesis of our clinical compounds and manufacture of drug product.

Following a review by GSK of the manufacturing process and equipment at the vendor that manufactures the ibrexafungerp drug substance, we became aware that a non-antibacterial beta-lactam drug substance was manufactured using equipment common to the manufacturing process for ibrexafungerp. Current FDA draft guidance recommends segregating the manufacture of non-antibacterial beta-lactam compounds from other compounds since beta-lactam compounds have the potential to act as sensitizing agents that may trigger hypersensitivity or an allergic reaction in some people. In the absence of the recommended segregation, there is a risk of cross contamination. It is not known whether any ibrexafungerp has been contaminated with a beta-lactam compound and we have not received any reports of adverse events due to the possible beta-lactam cross contamination. Nonetheless, out of an abundance of caution and in line with GSK’s recommendation, we have recalled BREXAFEMME (ibrexafungerp tablets) from the market and placed a temporary hold on clinical studies of ibrexafungerp, including the Phase 3 MARIO study.

The patient-level and clinical product recall has been initiated and we are working with an experienced vendor to manage the process. We have begun engaging with the FDA and during a meeting in September 2023, the FDA concurred with our voluntary hold and placed a clinical hold. We are working to provide additional information to the FDA and discuss potential paths for resolution of this issue. The clinical hold and recall affect our two ongoing clinical studies: the Phase 3 MARIO study and a Phase 1 lactation study. The hold does not impact the recently completed FURI, CARES, VANQUISH and SCYNERGIA

clinical studies, for which dosing is complete. The FDA determined that the compassionate use program for ibrexafungerp, which provides ibrexafungerp to patients with limited or no other treatment options, can continue provided the patient’s treating physician concludes a favorable benefit-risk assessment and the patient is made aware of and consents to the risk. This applies to patients currently in the program as well as for new patients, pending confirmation of available supply. Our preclinical stage compound, SCY-247, is not affected by these developments.

A drug manufacturing program subject to extensive governmental regulations requires robust quality assurance systems and experienced personnel with the relevant technical and regulatory expertise as well as strong project management skills. We believe we have a team that is capable of managing these activities until GSK assumes responsibility for them pursuant to the GSK License Agreement. We believe the primary third-party vendors with which we have agreements in place to support manufacturing and supply for clinical development have the required capabilities with respect to facilities, equipment and technical expertise, quality systems that meet global regulatory and compliance requirements, satisfactory regulatory inspection history from relevant health authorities and proven track records in supplying drug substance and drug product.

Collaborations and Licensing Agreements Associated with Our Core Drug Development Operations

We have a number of licensing and collaboration agreements associated with our core drug development operations, including the following:

We initially discovered and developed ibrexafungerp through a research collaboration with Merck Sharp & Dohme Corp. (Merck), a subsidiary of Merck & Co., Inc. In May 2013, Merck transferred to us all development and commercialization rights for ibrexafungerp (also known as MK-3118). This decision was made following a review and prioritization of Merck’s infectious disease portfolio. Under the terms of the agreement, we received all human health rights to ibrexafungerp, including all related technical documents, preclinical data, data from the seven Phase 1 trials conducted by Merck, and drug product and drug substance. The agreement continues until expiration of all royalty obligations. The agreement may be terminated if either party is in material breach and fails to remedy the breach after receiving written notice. In January 2014, Merck assigned the patents to us related to ibrexafungerp that it had exclusively licensed to us. Under the terms of the patent assignment, Merck no longer has responsibility to maintain the patents. Merck was originally eligible to receive milestones upon initiation of a Phase 2 clinical study, NDA submission and marketing approvals in each of the U.S., major European markets and Japan that could total up to $19 million. In addition, Merck will receive tiered royalties based on worldwide sales of ibrexafungerp. The aggregate royalties are mid- to high-single digits of net sales, and we expect to pay royalties on net sales of ibrexafungerp to Merck for no more than ten years from first commercial launch, on a country-by-country basis.

In December 2014, we entered into an amendment to the license agreement with Merck that defers the remittance of a milestone payment due to Merck, such that no amount will be due upon initiation of the first phase 2 clinical trial of a product containing the ibrexafungerp compound (the Deferred Milestone). The amendment also increased, in an amount equal to the Deferred Milestone, the milestone payment that will be due upon initiation of the first Phase 3 clinical trial of a product containing the ibrexafungerp compound. In December 2016 and January 2019, we entered into second and third amendments to the license agreement with Merck which clarified what would constitute the initiation of a Phase 3 clinical trial for the purpose of a milestone payment. In January 2019, a milestone payment became due to Merck as a result of the initiation of the VANISH Phase 3 VVC program and it was paid in March 2019.

On December 2, 2020, we entered into a fourth amendment to the license agreement with Merck. The amendment eliminates two cash milestone payments that we would have paid to Merck upon the first filing of a NDA, triggered by the

FDA acceptance for filing of our NDA for ibrexafungerp for the treatment of VVC, and first marketing approval in the U.S. in June 2021 for our NDA for ibrexafungerp for the treatment of VVC. These cash milestone payments would have been creditable against future royalties owed to Merck on net sales of ibrexafungerp. With the amendment, these milestones will not be paid in cash and, accordingly, credits will not accrue. Pursuant to the amendment, we will also forfeit the credits against future royalties that had accrued from a prior milestone payment already paid to Merck. All other key terms of the license agreement are unchanged.

In February 2021, we entered into an Exclusive License and Collaboration Agreement (the Hansoh License Agreement) with Hansoh (Shanghai) Health Technology Co., Ltd., and Jiangsu Hansoh Pharmaceutical Group Company Limited (collectively, Hansoh), pursuant to which we granted to Hansoh an exclusive license to research, develop and commercialize ibrexafungerp in the Greater China region, including mainland China, Hong Kong, Macau, and Taiwan. Under the terms of the Hansoh License Agreement, Hansoh shall be responsible for the development, regulatory approval and commercialization of ibrexafungerp in Greater China. We received a $10.0 million upfront payment and will also be eligible to receive up to $112.0 million in development and commercial milestones, plus low double-digit royalties on net product sales. The obligation to pay us royalties with respect to sales in a specified region will continue until the later of the date of expiration of all intellectual property and regulatory exclusivity for the product in the region and ten years from the first commercial sale, unless earlier terminated by Hansoh with advanced notice for convenience or under other specified circumstances.

In August 2013, we entered into an agreement with R-Pharm, CJSC (R-Pharm), a leading supplier of hospital drugs in Russia, granting them exclusive rights to develop and commercialize ibrexafungerp in the field of human health in Russia, Turkey, and certain Balkan, Central Asian, Middle Eastern and North African countries. We retained the right to commercialize ibrexafungerp in the Americas, Europe, and Asia. In November 2014, we entered into a supplemental arrangement with R-Pharm, whereby R-Pharm was informed of the modified IV formulation development plan and R-Pharm agreed to reimburse us for specifically identified IV formulation development and manufacturing costs incurred by us. We received a non-refundable upfront payment of $1.5 million from R-Pharm in August 2013 which was recognized over a period of 70 months and is fully amortized. This agreement is not material to our consolidated balance sheets, statements of operations, or statements of cash flows.

Government authorities in the United States, at the federal, state and local level, and in other countries extensively regulate, among other things, the research, development, testing, manufacture, including any manufacturing changes, packaging, storage, recordkeeping, labeling, advertising, promotion, distribution, marketing, import and export of pharmaceutical products such as those we are developing. The processes for obtaining regulatory approvals in the United States and in foreign countries, along with subsequent compliance with applicable statutes and regulations, require the expenditure of substantial time and financial resources.

In the United States, the FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act (FDCA), and implements regulations. The process of obtaining regulatory approvals and the subsequent compliance with appropriate federal, state, local and foreign statutes and regulations requires the expenditure of substantial time and financial resources. Failure to comply with the applicable U.S. requirements at any time during the product development process, approval process or after approval, may subject an applicant to a variety of administrative or judicial sanctions, such as the FDA’s refusal to approve pending NDAs, withdrawal of an approval, imposition of a clinical hold, issuance of warning letters, product recall requests, product seizures, total or partial suspension of production or distribution, injunctions, refusals of government contracts, restitution, disgorgement or civil or criminal penalties.

The process required by the FDA before a drug may be marketed in the United States generally involves the following:

After evaluating the NDA and all related information, the FDA may issue an approval letter, or, in some cases, a complete response letter. A complete response letter generally contains a statement of specific conditions that must be met in order to secure final approval of the NDA and may require additional clinical or preclinical testing in order for FDA to reconsider the application.

Preclinical studies include laboratory evaluation of product chemistry, toxicity and formulation, as well as animal studies to assess potential safety and efficacy. An IND sponsor must submit the results of the preclinical tests, together with manufacturing information, analytical data and any available clinical data or literature, among other things, to the FDA as part of an IND. Some preclinical testing may continue even after the IND is submitted. An IND automatically becomes effective 30 days after receipt by the FDA, unless before that time the FDA raises concerns or questions related to one or more proposed clinical trials and places the clinical trial on a clinical hold. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical trial can begin. As a result, submission of an IND may not result in the FDA allowing clinical trials to commence.

Clinical trials involve the administration of the investigational new drug to human subjects under the supervision of qualified investigators in accordance with GCP requirements, which include the requirement that all research subjects provide their informed consent in writing for their participation in any clinical trial. Clinical trials are conducted under protocols detailing, among other things, the objectives of the study, the parameters to be used in monitoring safety, and the effectiveness criteria to be evaluated. A protocol for each clinical trial and any subsequent protocol amendments must be submitted to the FDA as part of the IND. In addition, an IRB at each institution participating in the clinical trial must review and approve the plan for any clinical trial before it commences at that institution. Information about certain clinical trials must be submitted within specific timeframes to the National Institutes of Health (NIH) for public dissemination on their ClinicalTrials.gov website.

Human clinical trials are typically conducted in three sequential phases, which in some cases may overlap or be combined:

Phase 1: The drug is initially introduced into healthy human subjects or patients with the target disease or condition and tested for safety, dosage tolerance, absorption, metabolism, distribution, excretion and, if possible, to gain an early indication of its effectiveness.

Phase 2: The drug is administered to a limited patient population with the target disease to identify possible adverse effects and safety risks, to preliminarily evaluate the efficacy of the product for specific targeted diseases and to determine dosage tolerance and optimal dosage.

Phase 3: The drug is administered to an expanded patient population with the target disease, generally at geographically dispersed clinical trial sites, in well-controlled clinical trials to generate enough data to statistically evaluate the efficacy and safety of the product for approval, to establish the overall risk-benefit profile of the product, and to provide adequate information for the labeling of the product.

Progress reports detailing the results of the clinical trials must be submitted at least annually to the FDA and more frequently if serious adverse events occur. Phase 1, Phase 2 and Phase 3 clinical trials sometimes cannot be completed successfully within any specified period, or at all. Furthermore, the FDA or the sponsor may suspend or terminate a clinical trial at any time on various grounds, including a finding that the research subjects are being exposed to an unacceptable health risk. Similarly, an IRB can suspend or terminate approval of a clinical trial at its institution if the clinical trial is not being conducted in accordance with the IRB’s requirements or if the drug has been associated with unexpected serious harm to patients.

In some cases, the FDA may condition approval of an NDA for a product candidate on the sponsor’s agreement to conduct additional clinical trials to further assess the drug’s safety and effectiveness after NDA approval. Such post-approval trials are typically referred to as Phase 4 studies.

In some circumstances, the FDA may also order a sponsor to conduct post-approval clinical trials if new safety information arises raising questions about the drug’s risk-benefit profile. Those clinical trials are typically referred to as Post-Marketing Requirements (PMRs).

The FDA has various expedited development programs, including break-through therapy, fast track designation and priority review, that are intended to expedite or simplify the process for the development and FDA review of drugs that meet certain qualifications. The purpose of these programs is to provide important new drugs to patients earlier than under standard FDA review procedures.

The Generating Antibiotic Incentives Now Act (GAIN Act) is intended to encourage development of new antibacterial and antifungal drugs for the treatment of serious or life-threatening infections by providing certain benefits to sponsors, including extended exclusivity periods, fast track and priority review. To be eligible for these benefits a product in development must seek and be awarded designation as a QIDP.

To qualify as a QIDP according to the criteria established in the GAIN Act, a product must be an antibacterial or antifungal drug for human use intended to treat serious or life-threatening infections, including, those:

The FDA is required to facilitate the development, and expedite the review, of drugs that are intended for the treatment of a serious or life-threatening disease or condition for which there is no effective treatment and which demonstrate the potential to address unmet medical needs for the condition. Under the Fast Track program, the sponsor of a new drug candidate may request that the FDA designate the drug candidate for a specific indication as a Fast Track drug concurrent with, or after, the filing of the IND for the drug candidate. The FDA must determine if the drug candidate qualifies for Fast Track designation within 60 days of receipt of the sponsor's request.

If a drug candidate is granted Fast Track designation, the sponsor may engage in more frequent interactions with the FDA, and the FDA may review sections of the NDA before the application is complete. This rolling review is available if the applicant provides, and the FDA approves, a schedule for the submission of the remaining information and the applicant pays applicable user fees. However, the FDA's time period goal for reviewing an application does not begin until the last section of the NDA is submitted. Additionally, Fast Track designation may be withdrawn by the FDA if the FDA believes that the designation is no longer supported by data emerging in the clinical trial process.

Drugs manufactured or distributed pursuant to FDA approvals are subject to pervasive and continuing regulation by the FDA, including, among other things, requirements relating to recordkeeping, periodic reporting, product sampling and distribution, advertising and promotion and reporting of adverse experiences with the product. After approval, most changes to the approved product, such as adding new indications, manufacturing changes or other labeling claims, are subject to further testing requirements and prior FDA review and approval. There also are continuing annual user fee requirements for any marketed products and the establishments at which such products are manufactured, as well as application fees for supplemental applications with clinical data.

Even if the FDA approves a product, it may limit the approved indications for use of the product, require that contraindications, warnings or precautions be included in the product labeling, including a boxed warning, require that post‑approval studies, including Phase 4 clinical trials, be conducted to further assess a drug’s safety after approval, require testing and surveillance programs to monitor the product after commercialization, or impose other conditions, including distribution restrictions or other risk management mechanisms under a REMS, which can materially affect the potential market

and profitability of the product. The FDA may prevent or limit further marketing of a product based on the results of post‑marketing studies or surveillance programs.

In addition, drug manufacturers and other entities involved in the manufacture and distribution of approved drugs are required to register their establishments with the FDA and state agencies, and are subject to periodic unannounced inspections by the FDA and these state agencies for compliance with cGMP requirements. Changes to the manufacturing process are strictly regulated and often require prior FDA approval before being implemented. FDA regulations also require investigation and correction of any deviations from cGMP and impose reporting and documentation requirements upon the sponsor and any third‑party manufacturers that the sponsor may decide to use. Accordingly, manufacturers must continue to expend time, money and effort in the area of production and quality control to maintain cGMP compliance.

The FDA strictly regulates marketing, labeling, advertising and promotion of products that are placed on the market. Drugs may be promoted only for the approved indications and in accordance with the provisions of the approved label, although physicians, in the practice of medicine, may prescribe approved drugs for unapproved indications. However, pharmaceutical companies may share truthful and not misleading information that is otherwise consistent with the labeling. The FDA and other agencies actively enforce the laws and regulations prohibiting their promotion of off‑label uses, and a company that is found to have improperly promoted off‑label uses may be subject to significant civil, criminal and administrative liability.

In addition, the distribution of prescription pharmaceutical products is subject to the Prescription Drug Marketing Act, or PDMA, which regulates the distribution of drugs and drug samples at the federal level, and sets minimum standards for the registration and regulation of drug distributors by the states. Both the PDMA and state laws limit the distribution of prescription pharmaceutical product samples and impose requirements to ensure accountability in distribution.

Pediatric exclusivity is another type of non-patent marketing exclusivity in the United States and, if granted, provides for the attachment of an additional six months of regulatory protection to the term of any existing exclusivity, including the non-patent exclusivity periods described above, and to the regulatory term of any patent that has been submitted to FDA for the approved drug product. This six-month exclusivity may be granted based on the voluntary completion of a pediatric study or studies in accordance with an FDA-issued “Written Request” for such a study or studies.

If the NDA for a QIDP is approved by the FDA, the FDA will extend by an additional five years any non-patent marketing exclusivity period awarded, such as a five-year exclusivity period awarded for a new chemical entity. This extension is in addition to any pediatric exclusivity extension awarded. Eligibility for the extension will be denied if the product is approved for uses that would not meet the definition of a QIDP.

In the ordinary course of our business, we may process confidential, proprietary, and sensitive information, including personal data. Accordingly, we are, or may become, subject to numerous data privacy and security obligations, including federal, state, local, and foreign laws, regulations, guidance, and industry standards related to data privacy and security. Such obligations may include, without limitation, the Federal Trade Commission Act, the California Consumer Privacy Act of 2018 (CCPA), the Canadian Personal Information Protection and Electronic Documents Act, Canada’s Anti-Spam Legislation, the European Union’s General Data Protection Regulation 2016/679 (EU GDPR), the EU GDPR as it forms part of United Kingdom (UK) law by virtue of section 3 of the European Union (Withdrawal) Act 2018 (UK GDPR), and the Payment Card Industry Data Security Standard (PCI DSS). Several states within the United States have enacted or proposed data privacy and security laws. For example, Virginia passed the Consumer Data Protection Act, and Colorado passed the Colorado Privacy Act. Additionally, we are, or may become, subject to various U.S. federal and state consumer protection laws which require us to publish statements that accurately and fairly describe how we handle personal data and choices individuals may have about the way we handle their personal data.

The CCPA and EU GDPR are examples of the increasingly stringent and evolving regulatory frameworks related to personal data processing that may increase our compliance obligations and exposure for any noncompliance. For example, the CCPA imposes obligations on covered businesses to provide specific disclosures related to a business’s collection, use, and disclosure of personal data and to respond to certain requests from California residents related to their personal data (for example, requests to know of the business’s personal data processing activities, to delete the individual’s personal data, and to opt out of certain personal data disclosures). Also, the CCPA provides for civil penalties and a private right of action for data breaches which may include an award of statutory damages. In addition, the California Privacy Rights Act of 2020 (CPRA), effective January 1, 2023, expanded the CCPA by, among other things, giving California residents the ability to limit use of certain sensitive personal data, establishing restrictions on personal data retention, expanding the types of data breaches that are

subject to the CCPA’s private right of action, and establishing a new California Privacy Protection Agency to implement and enforce the new law.

Foreign data privacy and security laws (including but not limited to the EU GDPR and UK GDPR) impose significant and complex compliance obligations on entities that are subject to those laws. As one example, the EU GDPR applies to any company established in the EEA and to companies established outside the EEA that process personal data in connection with the offering of goods or services to data subjects in the EEA or the monitoring of the behavior of data subjects in the EEA. These obligations may include limiting personal data processing to only what is necessary for specified, explicit, and legitimate purposes; requiring a legal basis for personal data processing; requiring the appointment of a data protection officer in certain circumstances; increasing transparency obligations to data subjects; requiring data protection impact assessments in certain circumstances; limiting the collection and retention of personal data; increasing rights for data subjects; formalizing a heightened and codified standard of data subject consents; requiring the implementation and maintenance of technical and organizational safeguards for personal data; mandating notice of certain personal data breaches to the relevant supervisory authority(ies) and affected individuals; and mandating the appointment of representatives in the UK and/or the EU in certain circumstances.

See the section titled “Risk Factors” for additional information about the laws and regulations to which we may become subject and about the risks to our business associated with such laws and regulations.

In the United States our activities are subject to regulation by various federal, state and local authorities in addition to the FDA, including but not limited to, the Centers for Medicare & Medicaid Services, or CMS, other divisions of the U.S. Department of Health and Human Services, or HHS, such as the Office of Inspector General, the U.S. Department of Justice, or DOJ, and individual U.S. Attorney offices within the DOJ, and state and local governments. For example, in the United States, sales, marketing and scientific and educational programs also must comply with state and federal fraud and abuse laws, false claims laws, transparency laws, government price reporting, and health information privacy and security laws. These laws include the following:

For example, sales, marketing and scientific/educational grant programs must comply with the federal and state anti-fraud and abuse laws, false claims laws, the privacy provisions of the Health Insurance Portability and Accountability Act, or HIPAA, and payment transparency laws.

If our operations are found to be in violation of any of the federal and state healthcare laws described above or any other governmental regulations that apply to us, we may be subject to significant penalties, including civil, criminal and administrative sanctions, damages, disgorgement, monetary fines, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, imprisonment, integrity oversight and reporting obligations, and contractual damages.

To market any product outside of the United States, we would need to comply with numerous and varying regulatory requirements of other countries regarding safety and efficacy and governing, among other things, clinical trials, marketing authorization, commercial sales and distribution of our products. Whether or not we obtain FDA approval for a product, we would need to obtain the necessary approvals by the comparable regulatory authorities of foreign countries before we can commence clinical trials or marketing of the product in those countries. The approval process varies from country to country and can involve additional product testing and additional administrative review periods. The time required to obtain approval in other countries might differ from and be longer than that required to obtain FDA approval. Regulatory approval in one country does not ensure regulatory approval in another, but a failure or delay in obtaining regulatory approval in one country may negatively impact the regulatory process in others.

Our ability to commercialize BREXAFEMME and any of our product candidates successfully will depend in part on the extent to which the United States and foreign governmental authorities, private health insurers and other third-party payors establish appropriate coverage and reimbursement levels for our product candidates and related treatments. In many of the markets where we would commercialize a product following regulatory approval, the prices of pharmaceutical products are subject to direct price controls (by law) and to drug reimbursement programs with varying price control mechanisms. In the United States, no uniform policy of coverage and reimbursement for drug products exists among third-party payors. One third-party payor’s determination to provide coverage for a product candidate does not assure that other payors will also provide coverage for the product candidate. As a result, the coverage determination process is often time-consuming and costly.

Increasingly, third party payors are requiring that drug companies provide them with predetermined discounts from list prices and are challenging the prices charged for medical products. Further, such payors are increasingly challenging the price, examining the medical necessity and reviewing the cost effectiveness of medical product candidates. There may be especially significant delays in obtaining coverage and reimbursement for newly approved drugs. Third party payors may limit coverage to specific products on an approved list, known as a formulary, which might not include all FDA-approved drugs for a particular indication. We may need to conduct expensive pharmaco-economic studies to demonstrate the medical necessity and cost effectiveness of its products. As a result, the coverage determination process is often a time-consuming and costly process that will require us to provide scientific and clinical support for the use of its products to each payor separately, with no assurance that coverage and adequate reimbursement will be obtained. Additionally, third-party payors may refuse to include a particular branded drug in their formularies when a competing generic product is available. Under Medicare, hospitals are reimbursed under an inpatient prospective payment system. This pricing methodology provides a single payment amount to hospitals based on a given diagnosis-related group. As a result, with respect to Medicare reimbursement for services in the hospital inpatient setting, hospitals could have a financial incentive to use the least expensive drugs for the treatment of invasive fungal infections, particularly the IV formulations of these drugs, as they are typically administered in the hospital. Further, coverage policies and third-party reimbursement rates may change at any time. Even if favorable coverage and reimbursement status is attained for one or more products for which we receive regulatory approval, less favorable coverage policies and reimbursement rates may be implemented in the future.

Public and private health care payors control costs and influence drug pricing through a variety of mechanisms, including through negotiating discounts with the manufacturers and through the use of tiered formularies and other mechanisms that provide preferential access to certain drugs over others within a therapeutic class. Payors also set other criteria to govern the uses of a drug that will be deemed medically appropriate and therefore reimbursed or otherwise covered. In particular, many public and private health care payors limit reimbursement and coverage to the uses of a drug that are either approved by the FDA or that are supported by other appropriate evidence (for example, published medical literature) and appear in a recognized drug compendium. Drug compendia are publications that summarize the available medical evidence for particular drug products and identify which uses of a drug are supported or not supported by the available evidence, whether or not such uses have been approved by the FDA.

In the United States and some foreign jurisdictions there have been, and continue to be, several legislative and regulatory changes and proposed reforms of the healthcare system to contain costs, improve quality, and expand access to care. For example, in the United States the Affordable Care Act substantially changed the way healthcare is financed by both governmental and private insurers, and continues to significantly impact the U.S. pharmaceutical industry. There have been executive, judicial and congressional challenges to certain aspects of the Affordable Care Act. For example, on June 17, 2021 the U.S. Supreme Court dismissed a challenge on procedural grounds that argued the Affordable Care Act is unconstitutional in its entirety because the “individual mandate” was repealed by Congress. On August 16, 2022, President Biden signed the Inflation Reduction Act of 2022, or IRA, into law, which among other things, extends enhanced subsidies for individuals purchasing health insurance coverage in Affordable Care Act marketplaces through plan year 2025. The IRA also eliminates the "donut hole" under the Medicare Part D program beginning in 2025 by significantly lowering the beneficiary maximum out-of-pocket cost and creating a new manufacturer discount program. It is possible that the Affordable Care Act will be subject to judicial or Congressional challenges in the future. It is also unclear how such challenges and the healthcare reform measures of the Biden administration will impact the Affordable Care Act and our business.

Other legislative changes have been proposed and adopted in the United States since the Affordable Care Act was enacted. These changes included aggregate reductions to Medicare payments to providers of 2% per fiscal year, effective April 1, 2013, which, due to subsequent legislative amendments, including the Infrastructure Investment and Jobs Act, will stay in effect until 2032 unless additional Congressional action is taken. In January 2013, the American Taxpayer Relief Act of 2012 was signed into law, which, among other things, reduced Medicare payments to several providers, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. These laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect on customers for our drugs, if approved, and accordingly, our financial operations.

There also has been increasing legislative and enforcement interest in the United States with respect to drug pricing practices, which has resulted in several Congressional inquiries, Presidential executive orders and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drug products. For example, in July 2021, the Biden administration released an executive order, “Promoting Competition in the American Economy,” with multiple provisions aimed at prescription drugs. In response to Biden’s executive order, on September 9, 2021, HHS released a Comprehensive Plan for Addressing High Drug Prices that outlines principles for drug pricing reform and sets out a variety of potential legislative policies that Congress could pursue as well as potential administrative actions HHS can take to advance these principles. Further, the IRA, among other things (i) directs HHS to negotiate the price of certain high-expenditure, single-source drugs and biologics covered under Medicare and (ii) imposes rebates under Medicare Part B and Medicare Part D to penalize price increases that outpace inflation. These provisions take effect progressively starting in fiscal year 2023, although they may be subject to legal challenges. On August 29, 2023, HHS announced the list of the first ten drugs that will be subject to price negotiations, although the Medicare drug price negotiation program is currently subject to legal challenges. It is currently unclear how the IRA will be implemented but is likely to have a significant impact on the pharmaceutical industry, although they may be subject to legal challenges. . In response to the Biden administration’s October 2022 executive order, on February 14, 2023, HHS released a report outlining three new models for testing by the CMS Innovation Center which will be evaluated on their ability to lower the cost of drugs, promote accessibility, and improve quality of care. It is unclear whether the models will be utilized in any health reform measures in the future. Further, on December 7, 2023, the Biden administration announced an initiative to control the price of prescription drugs through the use of march-in rights under the Bayh-Dole Act. On December 8, 2023, the National Institute of Standards and Technology published for comment a Draft Interagency Guidance Framework for Considering the Exercise of March-In Rights which for the first time includes the price of a product as one factor an agency can use when deciding to exercise march-in rights. While march-in rights have not previously been exercised, it is uncertain if that will continue under the new framework. At the state level, legislatures have increasingly passed legislation and implemented regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. For example, on January 5, 2024, the FDA approved Florida’s Section 804 Importation Program, or SIP, proposal to import certain drugs from Canada for specific state healthcare programs. It is unclear how this program will be implemented, including which drugs will be chosen, and whether it will be subject to legal challenges in the United States or Canada. Other states have also submitted SIP proposals that are pending review by the FDA. Any such approved importation plans, when implemented, may result in lower drug prices for products covered by those programs.

We strive to protect the proprietary technology that we believe is important to our business, including seeking and maintaining patents intended to cover our product candidates and compositions, and their methods of use and other inventions that are commercially important to the development of our business. We also rely on trade secrets to protect aspects of our business that are not amenable to, or that we do not consider appropriate for, patent protection.

As of March 1, 2024, we are the owner of more than ten issued U.S. patents and more than 125 issued non-U.S. patents with claims to novel compounds, compositions containing them, processes for their preparation, and their uses as pharmaceutical agents, with terms expiring between 2027 and 2038. Of these patents, six U.S. patents relate to ibrexafungerp, and one U.S. patent relates to SCY-247. We are actively pursuing several U.S. patent applications and many non-U.S. patent applications in multiple jurisdictions worldwide.

Ibrexafungerp is protected in the United States by an issued composition of matter patent (U.S. Patent No. 8,188,085); three issued patents related to ibrexafungerp salts and polymorphs, including the citrate salt used in BREXAFEMME and our ongoing clinical trials; and two patents covering uses of ibrexafungerp in treatment or prevention of fungal infections. The ‘085 patent is currently set to expire in 2030. We have applied for patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984 (the Hatch-Waxman Act) and believe that the term of the ‘085 patent will be extended into 2035. The three patents covering the citrate salt of ibrexafungerp expire in 2035. The two patents covering uses of ibrexafungerp expire in 2038. The ibrexafungerp composition of matter is covered by a patent in more than 60 jurisdictions worldwide, with several more patent applications pending. Additional patent applications related to ibrexafungerp’s formulations and use as an antifungal agent have been filed and are currently pending. If granted, the new patent families could extend the patent protection for certain ibrexafungerp formulations or uses up to 2040. For this and more comprehensive risks related to our proprietary technology and processes, please see the section on “Risk Factors-Risks Relating to Our Intellectual Property.”

SCY-247 is protected in the United States by an issued composition of matter patent (U.S. Patent No. 7,863,465). The ‘465 patent is currently set to expire in 2029. The SCY-247 composition of matter is covered by a patent in several other jurisdictions worldwide, including Europe, Japan, and China.

As of March 1, 2024, we had 29 employees, all of whom were employed on a full-time basis. Our employees are engaged in administration, accounting and finance, research, clinical development, manufacturing, and business development functions. We believe our relations with our employees are good.

We were incorporated in the State of Delaware on November 4, 1999. Our corporate headquarters are located at 1 Evertrust Plaza, 13th Floor, Jersey City, New Jersey 07302.

Our corporate website address is www.scynexis.com. Our Annual Report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Exchange Act are available free of charge on our website. The information contained on, or that can be accessed through, our website is not part of this Annual Report, and the inclusion of our website address in this Annual Report is an inactive textual reference only.

In evaluating our business, you should carefully consider the following risks, as well as the other information contained in this Annual Report on Form 10-K. These risk factors could cause our actual results to differ materially from those contained in forward-looking statements we have made in this Annual Report on Form 10-K and those we may make from time to time. If any of the following risks actually occurs, our business, financial condition and operating results could be harmed. The risks and uncertainties described below are not the only ones facing us. Additional risks and uncertainties not presently known to us, or that we currently see as immaterial, may also harm our business.

We may not be able to realize the benefits we expect under the GSK License Agreement if we are not able to develop ibrexafungerp.

Our ability to generate revenues under the GSK License Agreement is dependent upon our ability to further develop ibrexafungerp. The risks described below with respect to ibrexafungerp will continue to be risks for us as they may impede our ability to receive some or all of the development, regulatory, commercial and sales milestones, and royalties, contemplated by the GSK License Agreement, which would materially and adversely affect our business and operating results.

We have a limited history of profitability, we have only one product approved for commercial sale that is licensed to GSK and is subject to a product recall, and to date we have generated limited revenue from product sales. As a result, our ability to curtail our losses and sustain profitability is unproven.

We do not expect to be profitable in the foreseeable future. We incurred net losses in each year since our inception except for net income of $67.0 million for the year ended December 31, 2023, primarily due to the $90.0 million upfront payment received under the GSK License Agreement. As of December 31, 2023, we had an accumulated deficit of approximately $355.2 million. On a prospective basis, our strategic focus, along with the commitment of our financial resources, will be directed towards the development of ibrexafungerp. We had cash, cash equivalents, and investments of $98.0 million as of December 31, 2023. We have suffered substantial losses from operations since inception and will require additional financing.

We expect to continue to incur significant expenses and operating losses for the foreseeable future. The net losses we incur may fluctuate significantly from quarter to quarter. We anticipate that our expenses will increase substantially as we:

In addition, our expenses could increase if we are required by the U.S. Food and Drug Administration, or the FDA, to perform studies in addition to, or that are larger than, those that we currently expect.

As a result of the foregoing, we expect to experience net losses and negative cash flows from operations for the foreseeable future, and we are unable to predict when, or if, we will be able to achieve profitability. Our losses and negative cash flows have had, and will continue to have a material adverse effect on our stockholders’ equity, financial position and statement of operations.

We expect a number of factors to cause our operating results to fluctuate on a quarterly and annual basis, which may make it difficult to predict our future performance.

Our financial condition and operating results have varied significantly in the past and will continue to fluctuate from quarter to quarter or year to year due to a variety of factors, many of which are beyond our control. The following factors relating to our business, as well as factors described elsewhere in this report, may contribute to these fluctuations:

Due to the various factors mentioned above, and others, the results of any quarterly or annual periods should not be relied upon as indications of future operating performance. Further, any financial projections we make are made as of the date we make them are subject to these risks and uncertainties, and these financial projections may not be realized.

We will continue to require substantial additional capital, and if we are unable to raise capital when needed we would be forced to delay, reduce or eliminate our development program for ibrexafungerp and our planned development for SCY-247.

Developing pharmaceutical products, including conducting preclinical studies and clinical trials, is expensive. If the FDA requires that we perform additional studies beyond those that we currently expect, our expenses could increase beyond what we currently anticipate, the timing of the submission of our planned NDAs could be delayed, and any potential product approval could be delayed. We may need to raise additional funds from additional issuances of equity and/or debt securities or otherwise obtain funding through strategic alliances or collaborations with third parties. In any event, we will require additional capital to complete development of, to seek regulatory approval for and, if approval is obtained, to commercialize and any product candidates we may seek to develop.

When we are required to secure additional financing, the additional fundraising efforts may divert our management from our day-to-day activities, which may adversely affect our ability to develop ibrexafungerp and any product candidates we may seek to develop. In addition, we cannot guarantee that financing will be available in sufficient amounts or on terms acceptable to us, if at all. If we are unable to raise additional capital when required or on acceptable terms, we may be required to:

If we are required to conduct additional fundraising activities and we are unable to raise additional capital in sufficient amounts or on terms acceptable to us, we will be prevented from pursuing development and commercialization efforts, which will have a material adverse effect on our business, operating results and prospects.

Our operating activities may be restricted as a result of covenants related to the indebtedness under our senior convertible notes and we may be required to repay the notes and our loan payable in an event of default, which could have a materially adverse effect on our business.

On March 7, 2019, we entered into a senior convertible note purchase agreement with Puissance Life Science Opportunities Fund VI (Puissance), pursuant to which we issued and sold to Puissance $16 million of our 6.0% senior convertible notes due 2025.

We may be required to repay the outstanding notes if an event of default occurs under the note purchase agreements. Under the note purchase agreements, an event of default will occur if, among other things: we fail to make payments under the note purchase agreement; we breach any of our covenants under the note purchase agreements, subject to specified cure periods with respect to certain breaches; or we or our subsidiaries become subject to bankruptcy, insolvency or reorganization proceedings. We may not have enough available cash or be able to raise additional funds through equity or debt financings to repay such indebtedness at the time any such event of default occurs. In this case, we may be required to delay, limit, reduce or terminate our product development or commercialization efforts or grant to others rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves. Our business, financial condition and results of operations could be materially adversely affected as a result of any of these events.

Unfavorable U.S. and global economic conditions could adversely affect our ability to access capital.

Our ability to access capital could be adversely affected by general conditions in the U.S. and global economies, the U.S. and global financial markets and adverse geopolitical and macroeconomic developments. U.S. and global market and economic

conditions have been, and continue to be, disrupted and volatile due to many factors, including component shortages and related supply chain challenges, geopolitical developments such as pandemics and conflicts and related sanctions, bank failures, and increasing inflation rates and the responses by central banking authorities to control such inflation, among others. General business and economic conditions that could affect our ability to access capital include fluctuations in economic growth, debt and equity capital markets, liquidity of the global financial markets, access to our liquidity within the U.S. banking system, the availability and cost of credit, investor and consumer confidence, and the strength of the economies in which we, our manufacturers and our suppliers operate.

Risks Relating to the Development, Regulatory Approval and Commercialization of Our Product Candidates For Human Use

We cannot be certain that ibrexafungerp will receive regulatory approval in the additional indications we are pursuing, and without regulatory approval it will not be possible to market ibrexafungerp for these indications. Regulatory approval is a lengthy, expensive and uncertain process and there is no guarantee that ibrexafungerp will be approved by the FDA for the additional indications we are pursuing.

Our ability to generate additional significant revenue related to sales of ibrexafungerp by GSK, will depend on the successful development and regulatory approval of ibrexafungerp for indications in addition to the treatment of VVC and RVVC.

We currently have one product approved for sale, BREXAFEMME, which is approved for the treatment of VVC and for the reduction in the incidence of RVVC, and we cannot guarantee that we will obtain more marketable products. The development and commercialization of a product candidate, including preclinical and clinical testing, manufacturing, quality systems, labeling, approval, record-keeping, selling, promotion, marketing and distribution of products, is subject to extensive regulation by the FDA in the United States and regulatory authorities in other countries, with regulations differing from country to country. We are not permitted to market product candidates in the United States until and unless we receive approval of an NDA or NDA supplement from the FDA. An NDA supplement has not been submitted for ibrexafungerp for the treatment of refractory invasive fungal infections, invasive pulmonary aspergillosis or any other indications. Obtaining approval of an NDA is a lengthy, expensive and uncertain process. An NDA must include extensive preclinical and clinical data and supporting information to establish the product candidate’s safety and effectiveness for each indication. The approval application must also include significant information regarding the chemistry, manufacturing and controls for the product. The product development and regulatory review process typically takes years to complete, involves numerous uncertainties and the potential for concerns to emerge late in the development process, and approval is never guaranteed. Even if a product is approved, the FDA may limit the indications for which the product may be used, require extensive warnings on the product labeling or require costly ongoing requirements for post-marketing clinical studies and surveillance or other risk management measures to monitor the safety or efficacy of the product candidate, including the imposition of a Risk Evaluation and Mitigation Strategy, or REMS. Markets outside of the United States also have requirements for approval of drug candidates with which we must comply prior to marketing. Obtaining regulatory approval for marketing of a product candidate in one country does not ensure we will be able to obtain regulatory approval in other countries, but a failure or delay in obtaining regulatory approval in one country may have a negative effect on the regulatory process in other countries. Also, any regulatory approval of a product candidate, once obtained, may be withdrawn. If ibrexafungerp or any of our other wholly-owned or partnered product candidates do not receive timely regulatory approval, or fail to maintain that regulatory approval, we may not be able to generate sufficient revenue to become profitable or to continue our operations. Moreover, the submission of our NDA or the receipt of regulatory approval does not assure commercial success of any approved product.

Although both the oral and IV formulations of ibrexafungerp have been granted Qualified Infectious Disease Product status and Fast Track designation, this does not guarantee that the length of the FDA review process will be significantly shorter than otherwise, or that ibrexafungerp will ultimately be approved by the FDA.

We applied to the FDA for, and received, the designation of the oral tablet and the IV formulations of ibrexafungerp for vulvovaginal candidiasis, invasive candidiasis and invasive aspergillosis as Qualified Infectious Disease Product (QIDP) under the Generating Antibiotic Incentives Now Act (GAIN Act). We also applied to the FDA for, and were granted, Fast Track designation for ibrexafungerp for these indications. Receipt of QIDP status and Fast Track designation in practice may not result in a faster development process, review or approval compared to drugs considered for approval under conventional FDA procedures and does not assure ultimate approval by the FDA or related GAIN Act exclusivity benefits.

Delays in the commencement, enrollment and completion of clinical trials could result in increased costs to us and delay or limit our ability to obtain regulatory approval for ibrexafungerp or any future product candidates.

We do not know whether our current clinical trials of ibrexafungerp will be completed on schedule or at all, or whether any future clinical trials of ibrexafungerp or any future product candidates we may seek to develop will be allowed to commence or, if commenced, will be completed on schedule or at all. The commencement, enrollment and completion of clinical trials can be delayed for a variety of reasons, including:

In addition, a clinical trial may be suspended or terminated by us, our current or any future partners, an institutional review board, the FDA or other regulatory authorities due to a number of factors, including:

If we are required to conduct additional clinical trials or other testing of ibrexafungerp or any future product candidates we may seek to develop, we may be delayed in obtaining, or may not be able to obtain, marketing approval for these product candidates.

In addition, if our current or any future partners have rights to and responsibility for development of ibrexafungerp or any future product candidates, they may fail to meet their obligations to develop and commercialize the product candidates, including clinical trials for these product candidates.

Changes in regulatory requirements and guidance may occur and we or any of our partners may be required by appropriate regulatory authorities to amend clinical trial protocols to reflect these changes. Amendments may require us or any of our partners to resubmit clinical trial protocols to independent review boards for re-examination, which may impact the costs, timing or successful completion of a clinical trial. If we or any of our partners experience delays in the completion of, or if we or our partners terminate, clinical trials, the commercial prospects for ibrexafungerp and any future product candidates we may seek to develop will be harmed, and our ability to generate revenue from sales of these product candidates will be prevented or delayed. In addition, many of the factors that cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of regulatory approval of a product candidate.

Clinical failure can occur at any stage of clinical development. Because the results of earlier clinical trials are not necessarily predictive of future results, any product candidate we or our current or potential future partners advance through clinical trials may not have favorable results in later clinical trials or receive regulatory approval.

Clinical failure can occur at any stage of clinical development. Clinical trials may produce negative or inconclusive results, and we or our partners may decide, or regulators may require us, to conduct additional clinical or preclinical testing. In addition, data obtained from tests are susceptible to varying interpretations, and regulators may not interpret data as favorably as we do, which may delay, limit or prevent regulatory approval. Success in preclinical testing and early clinical trials does not ensure that later clinical trials will generate the same results or otherwise provide adequate data to demonstrate the efficacy and safety of a product candidate. Frequently, product candidates that have shown promising results in early clinical trials have subsequently suffered significant setbacks in later clinical trials. In addition, the design of a clinical trial can determine whether its results will support approval of a product application, or approval of a supplemental application to add a new indication or other changes, and flaws or shortcomings in the design of a clinical trial may not become apparent until the clinical trial is well advanced. We may be unable to design and execute a clinical trial to support regulatory approval, or approval of supplemental applications for new indications or other changes. Further, clinical trials of potential products often reveal that it is not practical or feasible to continue development efforts. If ibrexafungerp or any future product candidates are found to be unsafe or lack efficacy, we or our collaborators will not be able to obtain regulatory approval for them and our business would be harmed. For example, if the results of our completed, ongoing or planned Phase 2 and Phase 3 clinical trials of ibrexafungerp do not achieve, to the satisfaction of regulators, the primary efficacy endpoints and demonstrate an acceptable level of safety, the prospects for approval of ibrexafungerp would be materially and adversely affected. A number of companies in the pharmaceutical industry, including those with greater resources and experience than us, have suffered significant setbacks in Phase 2 and Phase 3 clinical trials, even after seeing promising results in earlier clinical trials.

In some instances, there can be significant variability in safety and/or efficacy results between different trials of the same product candidate due to numerous factors, including differences in trial protocols and design, differences in size and type of the patient populations, adherence to the dosing regimen and the rate of dropout among clinical trial participants. Further, the patients taking ibrexafungerp often have other significant medical issues, such as organ transplants, cancer or other conditions in which their immune systems are suppressed, which makes it difficult to measure the effect of ibrexafungerp in the presence of these medical issues. We do not know whether any Phase 2, Phase 3 or other clinical trials we or any partners may conduct will demonstrate consistent and/or adequate efficacy and safety to obtain regulatory approval to market ibrexafungerp and any future product candidates we may seek to develop.

We have only submitted one NDA and one supplemental NDA before, and we may be unable to do so for ibrexafungerp in additional indications or any future product candidate we may seek to develop.

The conduct of successful Phase 2 and Phase 3 clinical trials is essential in obtaining regulatory approval, and the submission of a successful NDA is a complicated process. We have limited experience in preparing and submitting regulatory filings, have previously only sponsored four Phase 2 clinical trials and six Phase 3 clinical trials, and we have only submitted one NDA and one NDA Efficacy Supplement. Consequently, we may be unable to successfully and efficiently execute and complete our ongoing and planned clinical trials in a way that is acceptable to the FDA and leads to an approval of additional indications for ibrexafungerp or any future product candidate we may seek to develop. We may require more time and incur greater costs than our competitors and may not succeed in obtaining regulatory approvals of product candidates that we may seek to develop. In addition, failure to commence or complete, or delays in, our planned clinical trials would prevent us from or delay us in commercializing ibrexafungerp or any future product candidate we may develop.

The environment in which our regulatory submissions may be reviewed changes over time, which may make it more difficult to obtain regulatory approval of any of our product candidates we may seek to develop or commercialize.

The environment in which regulatory submissions are reviewed changes over time. For example, average review times at the FDA for NDAs have fluctuated over the last ten years, and we cannot predict the review time for any submission with any regulatory authorities. Review times can be affected by a variety of factors, including budget and funding levels and statutory, regulatory and policy changes. Moreover, in light of widely publicized events concerning the safety risks of certain drug products, regulatory authorities, members of Congress, the Government Accountability Office, medical professionals and the general public have raised concerns about potential drug safety issues. These events have resulted in the withdrawal of drug products, revisions to drug labeling that further limit use of the drug products and establishment of risk evaluation and mitigation strategies that may, for instance, restrict distribution of drug products. The increased attention to drug safety issues may result in a more cautious approach by the FDA to clinical trials. Data from preclinical studies and clinical trials may receive greater scrutiny with respect to safety, which may make the FDA or other regulatory authorities more likely to terminate clinical trials before completion, or require longer or additional clinical trials that may result in substantial additional expense, a delay or failure in obtaining approval or approval for a more limited indication or conditions of use than originally sought.

In addition, data obtained from preclinical studies and clinical trials are subject to different interpretations, which could delay, limit or prevent regulatory review or approval of product candidates. Changes in FDA personnel responsible for review of our submissions could also impact the manner in which our data are viewed. Furthermore, regulatory attitudes towards the data and results required to demonstrate safety and efficacy can change over time and can be affected by many factors, such as the emergence of new information, including information on other products, policy changes and agency funding, staffing and leadership. We do not know whether future changes to the regulatory environment will be favorable or unfavorable to our business prospects.

If BREXAFEMME, ibrexafungerp for other indications or any other future product candidates for which we receive regulatory approval do not achieve broad market acceptance, the revenue that is generated from their sales will be limited.

The commercial success of BREXAFEMME, ibrexafungerp for other indications or any other product candidates we may seek to develop will depend upon the acceptance of these product candidates among physicians, patients, the medical community and healthcare payors. The degree of market acceptance of product candidates will depend on a number of factors, including:

If BREXAFEMME, or ibrexafungerp for other indications or any future product candidates we may seek to develop are approved, but do not achieve an adequate level of acceptance by physicians, healthcare payors and patients, sufficient revenue may not be generated from these product candidates, and we may not become or remain profitable. In addition, efforts to educate the medical community and third-party payors on the benefits of our product candidates may require significant resources and may never be successful.

A significant use of antifungal drugs consists of treatment due to the presence of symptoms before diagnosis of the invasive fungal infections, and if recently approved diagnostic tools, or additional tools currently under development, for the quick diagnosis of invasive fungal infections are broadly used in the marketplace, the number of treatments using antifungal drugs may decrease significantly, decreasing the potential market for ibrexafungerp.

We believe that a large portion of the treatments using antifungal drugs are administered when symptoms of invasive fungal infections are present but a diagnosis of the infection has not yet been made, due to the rapid and potentially fatal progression of invasive fungal infections. Diagnostic tools recently approved by the FDA, or currently under development, for the rapid diagnosis of invasive fungal infections may significantly diminish the need to treat patients in advance of diagnosis of invasive fungal infections, which will reduce the potential market for ibrexafungerp. Moreover, if a rapid and accurate test of the susceptibility of a fungal infection to generically available treatments is developed and widely adopted, the market for ibrexafungerp may suffer.

If resistance to ibrexafungerp develops quickly or cross-resistance with echinocandins becomes more common, our business will be harmed.

We recognize that, over time, resistance develops against every antibacterial and antifungal drug. One or more strains of fungal pathogens may develop resistance to ibrexafungerp more rapidly than we currently expect, either because our hypothesis

of the mechanism of action is incorrect or because a strain of fungi undergoes some unforeseen genetic mutation that permits it to survive. Since we expect lower resistance relative to other antifungal drug classes to be a major factor in the commercialization of ibrexafungerp, rapid development of such resistance or development of cross resistance with echinocandins would have a major adverse impact on the acceptability and sales of ibrexafungerp.

Our approved product and product candidates may have undesirable side effects that may delay or prevent marketing approval, or, if approval is received, require them to be taken off the market or otherwise limit their sales.

It is impossible to predict when or if ibrexafungerp for indications other than VVC, RVVC or any other product candidate we may seek to develop will prove effective or safe, or whether we or GSK will receive marketing approval for ibrexafungerp for the treatment of indications other than VVC, RVVC, or whether we will receive marketing approval for any other products we may seek to develop. Unforeseen side effects from any product candidates could arise either during clinical development or, if approved, after the product has been marketed. The most commonly reported adverse events after oral administration of ibrexafungerp have been gastrointestinal (GI) events (i.e., nausea, diarrhea, vomiting). The gastrointestinal events reported have typically been transient (i.e., short duration), mild or moderate and not leading to discontinuation. The most commonly reported adverse events after IV administration of ibrexafungerp have been local reactions at the site of infusion. During our Phase 1 IV program in healthy volunteers, aimed to expand the safety margin that would allow greater flexibility of dosing options in patients, we observed three mild-to-moderate thrombotic events in healthy volunteers receiving the IV formulation of ibrexafungerp at the highest doses and highest concentrations. These events were reported to FDA as 15-day alert reports because they were unexpected and required anticoagulant therapy. The potential contribution of the IV formulation of ibrexafungerp to these events cannot be ruled out even though rates of thrombotic events due to intravenous catheters reported in the literature are comparable to those observed in the Phase 1 study.

Serious adverse events (SAEs) are common when conducting clinical trials in a seriously ill population such as patients experiencing invasive candidiasis. Several SAEs have been reported in our clinical trials but only four of the events have been deemed by the investigator to be potentially related to ibrexafungerp, although other contributing factors could not be ruled out. These four serious adverse events include: one event of elevation of liver function tests in a subject who received a single dose of oral ibrexafungerp (resolved) and three events secondary to thrombi formation at site of IV infusion with the cyclodextrin-based IV formulation.

Preclinical findings in the future could trigger the need to evaluate or monitor for specific potential safety concerns in clinical trials. The results of our clinical trials may show that ibrexafungerp and any future product candidates we may seek to develop cause undesirable or unacceptable side effects, which could interrupt, delay or halt clinical trials, resulting in delay of, or failure to obtain, marketing approval from the FDA and other regulatory authorities, or may lead us to abandon their development altogether.

We or others may subsequently identify undesirable or unacceptable side effects caused by BREXAFEMME or any future product candidate we may seek to develop, in which case:

Any of these events could prevent us or our current or potential future partners from achieving or maintaining market acceptance of the affected product or could substantially increase commercialization costs and expenses, which in turn could delay or prevent us from generating significant revenue from the sale of products.

We expect that BREXAFEMME, ibrexafungerp for the treatment of other indications, and any future product candidates we may seek to develop will face competition, and most of our competitors have significantly greater resources than we do.

The pharmaceutical industry is highly competitive, with a number of established, large pharmaceutical companies, as well as many smaller companies. There are many foreign and domestic pharmaceutical companies, biotechnology companies, public and private universities, government agencies and research organizations actively engaged in research and development of

products that may target the same markets as ibrexafungerp and any future product candidates we may seek to develop. We expect any products we develop to compete on the basis of, among other things, product efficacy, lack of significant adverse side effects and convenience and ease of treatment. For example, BREXAFEMME competes, and ibrexafungerp for other indications will compete, against current leading antifungal drugs, including voriconazole from the azole class, caspofungin from the echinocandin class, and liposomal amphotericin B from the polyenes class, many of which are currently available in generic form, or expected to be available in generic form at the time IV ibrexafungerp might be approved.

Compared to us, many of our competitors in the antifungal market have, and potential competitors for any future product candidates we may seek to develop may have, substantially greater:

As a result of these factors, our competitors and potential competitors may obtain regulatory approval of their products more rapidly than we do. Our competitors and potential competitors may also develop drugs that are more effective, more widely used and less costly than ours and may also be more successful than us in manufacturing and marketing their products and maintaining compliance with ongoing regulatory requirements.

Reimbursement decisions by third-party payors may have an adverse effect on pricing and market acceptance in the United States for BREXAFEMME, ibrexafungerp, and any future product candidates we may seek to develop. If there is not sufficient reimbursement for our products, it is less likely that our products will be purchased by patients and/or providers.

Successful commercialization of pharmaceutical products usually depends on the availability of coverage and adequate reimbursement from third-party payors, including commercial insurers and federal and state healthcare programs. Patients and/or healthcare providers who purchase drugs generally rely on third-party payors to reimburse all or part of the costs associated with such products. As such, coverage and adequate reimbursement from third-party payors can be essential to new product acceptance and may have an effect on pricing.

We do not know the extent to which BREXAFEMME will be able to obtain favorable coverage and adequate reimbursement from third-party payors. If we choose to bring other product candidates to market, they will be subject to similar uncertainty. We believe that ibrexafungerp and any other product candidates that are brought to market are less likely to be purchased by patients and/or providers if they are not adequately reimbursed by third-party payors.

In the United States, no uniform policy of coverage and reimbursement for drug products exists among third-party payors. As a result, the coverage determination process is often a time-consuming and costly process that will require us to provide scientific and clinical support for the use of our products to each payor separately, with no assurance that coverage and adequate reimbursement will be obtained. Furthermore, the market for our product candidates may depend on access to third-party payors’ drug formularies, or lists of medications for which third-party payors provide coverage and reimbursement. Industry competition to be included in such formularies results in downward pricing pressures on pharmaceutical companies. Third-party payors may refuse to include a particular branded drug in their formularies when a competing generic product is available. The adoption of certain payment methodologies by third-party payors may limit our ability to profit from the sale of ibrexafungerp. For example, under Medicare, hospitals are reimbursed under an inpatient prospective payment system. This pricing methodology provides a single payment amount to hospitals based on a given diagnosis-related group. As a result, with respect to Medicare reimbursement for services in the hospital inpatient setting, hospitals could have a financial incentive to use the least expensive drugs for the treatment of invasive fungal infections, particularly the IV formulations of these drugs, as they are typically administered in the hospital, which may significantly impact our ability to charge a premium for ibrexafungerp. Coverage policies and third-party reimbursement rates may change at any time. Even if favorable coverage and reimbursement status is attained for BREXAFEMME or other products for which the Company receives regulatory approval, less favorable coverage policies and reimbursement rates may be implemented in the future.

All third-party payors, whether governmental or commercial, are developing increasingly sophisticated methods of controlling healthcare costs, including mechanisms to encourage the use of generic drugs. Congress has also considered

policies to lower the reimbursement formulas in federal and state healthcare programs. Furthermore, coverage of, and reimbursement for, drugs can differ significantly from payor to payor and may require significant time and resources to obtain. In addition, new laws or regulations could impact future coverage and reimbursement.

In recent years, there have been numerous initiatives on the federal and state levels for comprehensive reforms affecting healthcare industry, including reforms related to the payment for, the availability of and reimbursement for healthcare services in the United States, including pharmaceutical products. These initiatives have ranged from proposals to fundamentally change federal and state healthcare reimbursement programs, including providing comprehensive healthcare coverage to the public under governmental funded programs, to minor modifications to existing programs.

In March 2010, Congress enacted the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, or the Affordable Care Act. The Affordable Care Act is designed to expand access to affordable health insurance, control healthcare spending, and improve healthcare quality. The law included provisions to, among other things, tie Medicare provider reimbursement to healthcare quality and incentives, mandatory compliance programs, enhanced transparency disclosure requirements, increased funding and initiatives to address fraud and abuse, and incentives to state Medicaid programs to expand their coverage and services. It also imposed an annual tax on pharmaceutical manufacturers or importers who sell “branded prescription drugs.” There have been executive, judicial and Congressional challenges to certain aspects of the Affordable Care Act. For example, the Tax Cuts and Jobs Act of 2017 included a provision repealing, effective January 1, 2019, the tax-based shared responsibility payment imposed by the Affordable Care Act on certain individuals who fail to maintain qualifying health coverage for all or part of a year that is commonly referred to as the “individual mandate”.

On June 17, 2021 the U.S. Supreme Court dismissed a challenge on procedural grounds that argued the Affordable Care Act is unconstitutional in its entirety because the “individual mandate” was repealed by Congress. On August 16, 2022, President Biden signed the Inflation Reduction Act of 2022, or IRA, into law, which among other things, extends enhanced subsidies for individuals purchasing health insurance coverage in Affordable Care Act marketplaces through plan year 2025. The IRA also eliminates the "donut hole" under the Medicare Part D program beginning in 2025 by significantly lowering the beneficiary maximum out-of-pocket cost and creating a new manufacturer discount program. It is possible that the Affordable Care Act will be subject to judicial or Congressional challenges in the future. It is unclear how such challenges and the healthcare reform measures of the Biden Administration will impact the Affordable Care Act and our business.

In addition, other legislative changes have been proposed and adopted in the United States since the Affordable Care Act was enacted. These changes included aggregate reductions to Medicare payments to providers of up to 2% per fiscal year, effective April 1, 2013, which, due to subsequent legislative amendments, including the Infrastructure Investment and Jobs Act, will stay in effect until 2032 unless additional Congressional action is taken.

Further, there has been heightened governmental scrutiny in the United States of pharmaceutical pricing practices in light of the rising cost of prescription drugs. Such scrutiny has resulted in several recent congressional inquiries, Presidential executive orders, and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for products. For example, in July 2021, the Biden administration released an executive order, “Promoting Competition in the American Economy,” with multiple provisions aimed at prescription drugs. In response to Biden’s executive order, on September 9, 2021, the U.S. Department of Health and Human Services, or HHS, released a Comprehensive Plan for Addressing High Drug Prices that outlines principles for drug pricing reform and sets out a variety of potential legislative policies that Congress could pursue as well as potential administrative actions HHS can take to advance these principles. Further, the IRA, among other things (i) directs HHS to negotiate the price of certain high-expenditure, single-source drugs and biologics covered under Medicare and (ii) imposes rebates under Medicare Part B and Medicare Part D to penalize price increases that outpace inflation. These provisions take effect progressively starting in fiscal year 2023. On August 29, 2023, HHS announced the list of the first ten drugs that will be subject to price negotiations, although the Medicare drug price negotiation program is currently subject to legal challenges. It is unclear how the IRA will be implemented but is likely to have a significant impact on the pharmaceutical industry. In response to the Biden administration’s October 2022 executive order, on February 14, 2023, HHS released a report outlining three new models for testing by the CMS Innovation Center which will be evaluated on their ability to lower the cost of drugs, promote accessibility, and improve quality of care. It is unclear whether the models will be utilized in any health reform measures in the future. Further, on December 7, 2023, the Biden administration announced an initiative to control the price of prescription drugs through the use of march-in rights under the Bayh-Dole Act. On December 8, 2023, the National Institute of Standards and Technology published for comment a Draft Interagency Guidance Framework for Considering the Exercise of March-In Rights which for the first time includes the price of a product as one factor an agency can use when deciding to exercise march-in rights. While march-in rights have not previously been exercised, it is uncertain if that will continue under the new framework.

We cannot predict what healthcare reform initiatives may be adopted in the future, particularly in light of the new presidential administration. Further federal, state and foreign legislative and regulatory developments are likely, and we expect ongoing initiatives to increase pressure on drug pricing, which could have a negative impact on our sales of any future approved products.

We expect that a portion of the market for BREXAFEMME, ibrexafungerp for other indications, and any other product candidates we may seek to develop will be outside the United States. However, our product candidates may never receive approval or be commercialized outside of the United States.

Before we or any commercial partners (including GSK) can market and commercialize any product candidates outside of the United States, there are numerous and varying regulatory requirements of other countries that will apply. Research and marketing authorization procedures vary among countries and can involve additional product testing and administrative review periods. The marketing authorization process in other countries may include all of the risks detailed above regarding failure to obtain FDA approval in the United States as well as other risks. Regulatory approval in one country does not ensure regulatory approval in another, but a failure or delay in obtaining regulatory approval in one country, or identification of potential safety concerns in one country, may have a negative effect on the regulatory process in others. Failure to obtain regulatory approval in other countries or any delay or setback in obtaining such approval could have the same adverse effects detailed above regarding FDA approval in the United States. As described above, such effects include the risks that:

Foreign countries may have requirements for marketing authorization holders or distributors to have a legal or physical presence in that country, and consideration of and compliance with these requirements may result in additional time and expense before we can pursue or obtain marketing authorization in foreign jurisdictions. If we do receive approval in other countries, we may enter into sales and marketing arrangements with third parties for international sales of any approved products.

BREXAFEMME, ibrexafungerp, or any other future product candidates we may seek to develop, may still face future development and regulatory difficulties.

For BREXAFEMME, ibrexafungerp, or any other future product candidates we may seek to develop, regulatory authorities may still impose significant restrictions on a product’s indicated uses or marketing or impose ongoing requirements for potentially costly post-approval studies. Given the number of high profile adverse events with certain drug products, regulatory authorities may require, as a condition of approval, costly risk evaluation and mitigation strategies, which may include safety surveillance, restricted distribution and use, patient education, enhanced labeling, expedited reporting of certain adverse events, pre-approval of promotional materials and restrictions on direct-to-consumer advertising. For example, any labeling approved for any of our product candidates may include a restriction on the term of its use, or it may not include one or more intended indications. Furthermore, any new legislation addressing drug safety issues could result in delays or increased costs during the period of product development, clinical trials and regulatory review and approval, as well as increased costs to assure compliance with any new post-approval regulatory requirements. Any of these restrictions or requirements could force us or our partners to conduct costly studies.

BREXAFEMME, ibrexafungerp, and any other future product candidates we may seek to develop will also be subject to ongoing regulatory requirements for the packaging, storage, advertising, promotion, record-keeping and submission of safety and other post-market information on the drug. In addition, approved products, manufacturers and manufacturers’ facilities are required to comply with extensive FDA requirements, including ensuring that quality control and manufacturing procedures conform to current Good Manufacturing Practices (cGMP). As such, we and our contract manufacturers, which we will be responsible for overseeing and monitoring for compliance, are subject to continual review and periodic inspections to assess compliance with cGMP. Accordingly, we and others with whom we work must continue to expend time, money and effort in all areas of regulatory compliance, including manufacturing, production and quality control. The FDA may hold us responsible for any deficiencies or noncompliance of our contract manufacturers in relation to ibrexafungerp and any other future product candidates we may seek to develop. Failure to follow cGMP can result in products being deemed adulterated, which carries significant legal implications. We will also be required to engage in pharmacovigilance activities and report certain adverse reactions and production problems, if any, to the FDA and to comply with certain requirements concerning advertising and promotion for products. Promotional communications with respect to prescription drugs are subject to a variety of legal and regulatory restrictions and must be consistent with the information in the product’s approved label. As such, we may not

promote products for indications or uses for which they do not have approval. Failure to comply with FDA advertising and promotion standards, which are often subject to interpretation by regulators, may result in a wide range of exposure and liability for us.

If a regulatory agency discovers previously unknown problems with a product, such as adverse events of unanticipated severity or frequency, or problems with the facility where the product is manufactured or disagrees with the promotion, marketing or labeling of a product, a regulatory agency may impose restrictions on that product or us, including requiring withdrawal of the product from the market. If the manufacturing or marketing of products fail to comply with applicable regulatory requirements, a regulatory agency may:

Non-compliance may also open a company to potential whistleblower lawsuits and the potential for liability under the False Claims Act.

Pharmaceutical companies are subject to significant ongoing regulatory obligations and oversight, which may result in significant additional expense and limit our ability to commercialize our products.

We are subject to regulation by other regional, national, state and local agencies, including the Department of Justice, the Office of Inspector General of the U.S. Department of Health and Human Services and other regulatory bodies. Violations of any of such laws and regulations could result in significant penalties being assessed against us.

The federal Anti-Kickback Statute prohibits, among other things, knowingly and willfully offering, paying, soliciting, or receiving remuneration to induce or in return for purchasing, leasing, ordering or arranging for the purchase, lease or order of any healthcare item or service reimbursable under Medicare, Medicaid or other federally financed healthcare programs. This statute has been interpreted to apply to arrangements between pharmaceutical companies on one hand and prescribers, purchasers and formulary managers on the other. The Affordable Care Act, among other things, clarified that a person or entity need not have actual knowledge of the federal Anti-Kickback Statute or specific intent to violate it, in order to have committed a violation. In addition, the Affordable Care Act amended the federal civil False Claims Act to provide that a claim that includes items or services resulting from a violation of the federal Anti-Kickback Statute, constitutes a false or fraudulent claim for purposes of the federal civil False Claims Act. There are a number of statutory exceptions and regulatory safe harbors protecting certain common activities from prosecution or other regulatory sanctions, however, the exceptions and safe harbors are drawn narrowly, and practices that do not fit squarely within an exception or safe harbor may be subject to scrutiny.

The federal civil and criminal false claims laws, including the federal civil False Claims Act, and civil monetary penalties law, prohibit any person from, among other things, knowingly presenting, or causing to be presented, claims for payment of government funds that are false or fraudulent or knowingly making, or causing to be made, a false record or statement material to a false or fraudulent claim to avoid, decrease or conceal an obligation to pay money to the federal government. Many pharmaceutical and other healthcare companies have been investigated and have reached substantial financial settlements with the federal government under these laws for a variety of alleged marketing activities, including providing free product to customers with the expectation that the customers would bill federal programs for the product; providing consulting fees, grants, free travel, and other benefits to physicians to induce them to prescribe the company’s products; and inflating prices reported to private price publication services, which are used to set drug payment rates under government healthcare programs. Companies have been prosecuted for causing false claims to be submitted because of the marketing of their products for unapproved uses and have also been prosecuted on other legal theories of Medicare and Medicaid fraud.

The federal Health Insurance Portability and Accountability Act of 1996. or HIPAA, which prohibits, among other things, knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program, regardless of

the payor (e.g., public or private). Similar to the federal Anti-Kickback Statute, a person or entity need not have actual knowledge the statute or specific intent to violate it, in order to have committed a violation.

HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, and their implementing regulations, which impose certain obligations with respect to safeguarding the privacy, security and transmission of individually identifiable health information on “covered entities,” such as certain healthcare providers, health plans, and healthcare clearinghouses and their respective “business associates,” as well as their covered subcontractors, that perform services for them, which involve the creation, receipt, use, maintenance, transmission or disclosure of, individually identifiable health information for or on behalf of a covered entity.

The Physician Payments Sunshine Act, created under the Affordable Care Act, which require certain manufacturers of drugs, devices, biologics and medical supplies for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program (with certain exceptions) to report annually to the Centers for Medicare and Medicaid Services information related to payments or other transfers of value made to physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors), other healthcare professionals (such as physician assistants and nurse practitioners), and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family members.

The majority of states also have statutes or regulations similar to these laws, which apply to items and services reimbursed under Medicaid and other state programs, or, in several states, apply regardless of the payor. Some of these states also prohibit certain marketing related activities including the provision of gifts, meals, or other items to certain health care providers. In addition, certain states, including California, Connecticut, Nevada, and Massachusetts, require pharmaceutical companies to implement compliance programs or marketing codes. Certain states also require pharmaceutical companies to file periodic reports with the state on sales, marketing, pricing, clinical trials and/or other activities, and/or register their sales and medical representatives.

Compliance with various federal and state laws is difficult and time consuming, and companies that violate them may face substantial penalties. The potential sanctions include significant administrative, civil and criminal penalties, including monetary fines, exclusion from participation in federal health care programs, integrity oversight and reporting obligations to resolve allegations of non-compliance with these laws, disgorgement, criminal fines, imprisonment, contractual damage, reputational harm, diminished profits and future earnings, and curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our results of operations. Because of the breadth of these laws and the lack of extensive legal guidance in the form of regulations or court decisions, it is possible that some of our business activities or those of our commercial partners could be subject to challenge under one or more of these laws. Such a challenge could have a material adverse effect on our business and financial condition and growth prospects.

We could become subject to government investigations and related subpoenas. Such subpoenas are often associated with previously filed qui tam actions, or lawsuits filed under seal under the federal civil False Claims Act. Qui tam actions are brought by private plaintiffs suing on behalf of the federal government for alleged federal civil False Claims Act violations. The time and expense associated with responding to such subpoenas, and any related qui tam or other actions may be extensive, and we cannot predict the results of our review of the responsive documents and underlying facts or the results of such actions. Responding to government investigations, defending any claims raised, and any resulting fines, restitution, damages and penalties, settlement payments or administrative actions, as well as any related actions brought by stockholders or other third parties, could have a material impact on our reputation, business and financial condition and divert the attention of our management from operating our business.

The number and complexity of both federal and state laws continues to increase, and additional governmental resources are being added to enforce these laws and to prosecute companies and individuals who are believed to be violating them. In particular, the Affordable Care Act includes a number of provisions aimed at strengthening the government’s ability to pursue federal Anti-Kickback Statute and federal False Claims Act cases against pharmaceutical manufacturers and other healthcare entities, including substantially increased funding for healthcare fraud enforcement activities, enhanced investigative powers, and amendments to the federal civil False Claims Act that make it easier for the government and whistleblowers to pursue cases for alleged kickback and false claim violations. Responding to a government investigation or enforcement action would be expensive and time-consuming and could have a material adverse effect on our business and financial condition and growth prospects.

If we fail to comply with applicable federal, state, or local regulatory requirements, we could be subject to a range of regulatory actions that could affect our ability to commercialize our products and could harm or prevent sales of any affected products that we are able to commercialize, or could substantially increase the costs and expenses of commercializing and marketing our products. Any threatened or actual government enforcement action could also generate adverse publicity and require that we devote substantial resources that could otherwise be used in other aspects of our business.

Regulations, guidelines and recommendations published by various government agencies and organizations may affect the use of ibrexafungerp and any future product candidates we may seek to develop.

Government agencies may issue regulations and guidelines directly applicable to us, our partners or our potential future partners and our product candidates. In addition, professional societies, practice management groups, private health/science foundations and organizations involved in various diseases from time to time publish guidelines or recommendations to the healthcare and patient communities. These various sorts of recommendations may relate to such matters as product usage, dosage, and route of administration and use of related or competing therapies. Changes to these recommendations or other guidelines advocating alternative therapies could result in decreased use of ibrexafungerp and any future product candidates we may seek to develop, which may adversely affect our results of operations.

Our ability to utilize our net operating loss carryforwards and certain other tax attributes may be limited.

Under current law, federal net operating losses incurred in tax years beginning after December 31, 2017, may be carried forward indefinitely, but the deductibility of such federal net operating loss carryforwards in a taxable year is limited to 80% of taxable income in such year. Portions of our state and federal net operating loss carryforwards began to expire in 2019. In addition, under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended, and corresponding provisions of state law, if a corporation undergoes an “ownership change” (generally defined as a greater than 50 percentage point change (by value) in the equity ownership of certain stockholders over a rolling three-year period), the corporation’s ability to use its pre-change net operating loss carryforwards and other pre-change tax attributes to offset its post-change income and taxes may be limited. We have determined that ownership changes have occurred and as a result, a portion of our NOL carryforwards are limited. We may also experience ownership changes in the future as a result of subsequent issuances of our common stock or other shifts in our stock ownership some of which may be outside of our control. In addition, at the state level, there may be periods during which the use of net operating loss carryforwards is suspended or otherwise limited, which could accelerate or permanently increase state taxes owed. As a result, we may be unable to use all or a material portion of our net operating loss carryforwards and other tax attributes, which could adversely affect our future cash flows.

Uncertainties in the interpretation and application of existing, new and proposed tax laws and regulations could materially affect our tax obligations and effective tax rate.

The tax regimes to which we are subject or under which we operate are unsettled and may be subject to significant change. The issuance of additional guidance related to existing or future tax laws, or changes to tax laws, tax treaties or regulations proposed or implemented by the current or a future U.S. presidential administration, Congress, or taxing authorities in other jurisdictions, including jurisdictions outside of the United States, could materially affect our tax obligations and effective tax rate. To the extent that such changes have a negative impact on us, including as a result of related uncertainty, these changes may adversely impact our business, financial condition, results of operations, and cash flows.

The amount of taxes we pay in different jurisdictions depends on the application of the tax laws of various jurisdictions, including the United States, to our international business activities, the relative amounts of income before taxes in the various jurisdictions in which we operate, new or revised tax laws, or interpretations of tax laws and policies, the outcome of current and future tax audits, examinations or administrative appeals, our ability to realize our deferred tax assets, and our ability to operate our business in a manner consistent with our corporate structure and intercompany arrangements. The taxing authorities of the jurisdictions in which we operate may challenge our methodologies for pricing intercompany transactions pursuant to our intercompany arrangements or disagree with our determinations as to the income and expenses attributable to specific jurisdictions. If such a challenge or disagreement were to occur, and our position was not sustained, we could be required to pay additional taxes, interest, and penalties, which could result in one-time tax charges, higher effective tax rates, reduced cash flows, and lower overall profitability of our operations. Our financial statements could fail to reflect adequate reserves to cover such a contingency. Similarly, a taxing authority could assert that we are subject to tax in a jurisdiction where we believe we have not established a taxable connection, often referred to as a “permanent establishment” under international tax treaties, and such an assertion, if successful, could increase our expected tax liability in one or more jurisdictions.

For tax years beginning after December 31, 2021, legislation commonly referred to as the “Tax Cuts and Jobs Act” requires taxpayers to capitalize and amortize certain research and development expenditures over five years if incurred in the United States and fifteen years if incurred in foreign jurisdictions, rather than deducting them currently. Although there have been legislative proposals to repeal or defer the capitalization requirement to later years, there can be no assurance that the provision will be repealed or otherwise modified.

We are dependent on our license agreement with GSK to commercialize ibrexafungerp other than in the Greater China region and in the Russian Federation and certain other countries, and if GSK is not successful in commercializing ibrexafungerp in these areas, we will lose a significant source of potential revenue.

Under the GSK License Agreement, GSK is to pay us milestone payments upon our achievement of specified regulatory, commercial and sales milestone events, as well as royalties on sales of ibrexafungerp in those countries in its territory. If GSK

determines not to pursue commercialization of ibrexafungerp in those countries, we will not receive any commercial or sales milestone or royalty payments under the GSK License Agreement.

We are dependent on our existing third-party collaboration with Hansoh to commercialize ibrexafungerp in the Greater China region, and if Hansoh is not successful in commercializing ibrexafungerp in these areas, we will lose a significant source of potential revenue.

We currently have an exclusive license and collaboration agreement with Hansoh who will pay us milestone payments upon the achievement of specified development and commercial milestones. In addition, Hansoh will pay us royalties upon sales of ibrexafungerp by Hansoh. We are relying on Hansoh to commercialize ibrexafungerp in the Greater China area, including mainland China, Hong Kong, Macau, and Taiwan, and if Hansoh is not able to commercialize ibrexafungerp in those countries, or determines not to pursue commercialization of ibrexafungerp in those countries, we will not receive any milestone or royalty payments under the agreement.

We are dependent on our existing third-party collaboration with R-Pharm to commercialize ibrexafungerp in the Russian Federation and certain other countries, and if R-Pharm is not successful in commercializing ibrexafungerp in those countries, we will lose a significant source of potential revenue.

We currently have a development license and supply agreement with R-Pharm, a leading supplier of hospital drugs in Russia, pursuant to which we license to R-Pharm rights to develop and commercialize ibrexafungerp in the field of human health in Russia and certain smaller non-core markets. R-Pharm will pay us milestone payments upon the achievement of specified milestones, including registration of ibrexafungerp in a country and upon the achievement of specified levels of sales. In addition, R-Pharm will pay us royalties upon sales of ibrexafungerp by R-Pharm. We are relying on R-Pharm to commercialize ibrexafungerp in the countries covered by our agreement with it, and if R-Pharm is not able to commercialize ibrexafungerp in those countries, or determines not to pursue commercialization of ibrexafungerp in those countries, we will not receive any milestone or royalty payments under the agreement.

On February 24, 2022, Russia launched an invasion of Ukraine which has resulted in increased volatility in various financial markets and across various sectors. The U.S. and other countries, along with certain international organizations, have imposed economic sanctions on Russia and certain Russian individuals, banking entities and corporations as a response to the invasion. The extent and duration of the military action, resulting sanctions and future market disruptions in the region are impossible to predict. Moreover, the ongoing effects of the hostilities and sanctions may not be limited to Russia and Russian companies and may spill over to and negatively impact other regional and global economic markets of the world, including Europe and the U.S. The ongoing military action along with the potential for a wider conflict could further increase financial market volatility and cause negative effects on regional and global economic markets, industries, and companies. It is not currently possible to determine the severity of any potential adverse impact of this event on our financial condition, or more broadly, upon the global economy.

We may not be successful in establishing and maintaining development and commercialization collaborations, which could adversely affect our ability to develop and commercialize product candidates.

Developing pharmaceutical products, conducting clinical trials, obtaining regulatory approval, establishing manufacturing capabilities and marketing approved products is expensive. Consequently, a portion of our strategy is to license to third parties rights to develop and commercialize product candidates, including candidates we have discovered other than ibrexafungerp, and if these third parties do not perform under our agreements with them, we will not receive any revenue from these collaborations. For example, we currently have a development license and supply agreement with R-Pharm, pursuant to which we license to R-Pharm rights to develop and commercialize ibrexafungerp in the field of human health in Russia and certain smaller non-core markets, and if ibrexafungerp receives marketing approval, we may enter into additional sales and marketing arrangements with third parties for international sales. If we are unable to enter into any of these arrangements on acceptable terms, or at all, we may be unable to market and sell ibrexafungerp and any future product candidates we may seek to develop in certain markets. We expect to face competition in seeking appropriate collaborators. Moreover, collaboration arrangements are complex and time consuming to negotiate, document and implement and they may require substantial resources to maintain. We may not be successful in our efforts to establish and implement collaborations or other alternative arrangements for the development of product candidates. When we partner with a third party for development and commercialization of a product candidate, we can expect to relinquish to the third party some or all of the control over the future success of that product candidate. Our collaboration partner may not devote sufficient resources to the commercialization of product candidates or may otherwise fail in their commercialization. The terms of any collaboration or other arrangement that we establish may not be favorable to us. In addition, any collaboration that we enter into may be unsuccessful in the development and commercialization of product candidates. In some cases, we may be responsible for continuing preclinical and initial clinical development of a partnered product candidate or research program, and the payment we receive from our collaboration partner may be insufficient to cover the cost of this development. If we are unable to reach agreements with suitable collaborators for product candidates, we could face increased costs, we may be forced to limit the number of product candidates we can commercially develop or the territories in which we commercialize them and we might fail to commercialize products or

programs for which a suitable collaborator cannot be found. If we fail to achieve successful collaborations, our operating results and financial condition will be materially and adversely affected.

We depend on third-party contractors for a substantial portion of our drug development activities and may not be able to control their work as effectively as if we performed these functions ourselves.

We outsource, and intend to continue to outsource, substantial portions of our drug development activities to third-party service providers, including manufacturing and the conduct of our clinical trials and various preclinical studies. Our agreements with third-party service providers and CROs are and will be on a study-by-study basis and typically short-term. In all cases, we expect to be able to terminate the agreements with notice and be responsible for the supplier’s previously incurred costs.

Because we rely on third parties, our internal capacity to perform these functions is limited. Outsourcing these functions involves risk that third parties may not perform to our standards, may not produce results in a timely manner or may fail to perform at all. Even if we outsource activities, in most cases regulators will hold us responsible for the compliance of the activities performed, and hold us responsible for oversight and monitoring of the activities. In addition, the use of third-party service providers requires us to disclose our proprietary information to these parties, which could increase the risk that this information will be misappropriated. There are a limited number of third-party service providers that have the expertise required to achieve our business objectives. Identifying, qualifying and managing performance of third-party service providers can be difficult and time consuming and could cause delays in our development programs. We currently have a small number of employees devoted to clinical development activities, which limits the internal resources we have available to identify and monitor our third-party providers. To the extent we are unable to identify, retain and successfully manage the performance of third-party service providers in the future, our business may be adversely affected.

As we do not intend to own or operate facilities for manufacturing, storage and distribution of drug substance or drug product we are and will be dependent on third parties for the manufacture of ibrexafungerp. If we experience problems with any of these third parties, the commercial manufacturing of ibrexafungerp could be delayed.

The inability to manufacture sufficient commercial supplies of ibrexafungerp could adversely affect product commercialization. We do not currently have any agreements with third-party manufacturers for the long-term commercial supply of ibrexafungerp. We may encounter technical difficulties or delays in the transfer of ibrexafungerp manufacturing on a commercial scale to a third-party manufacturer, or may be unable to enter into agreements for commercial supply with third-party manufacturers, or may be unable to do so on acceptable terms.

We may not be able to establish additional sources of supply for ibrexafungerp and any future product candidates we may seek to develop. These suppliers are subject to regulatory requirements covering manufacturing, testing, quality control and record keeping relating to product candidates and are also subject to ongoing inspections by the regulatory agencies. Failure by any of our suppliers to comply with applicable regulations may result in long delays and interruptions to our product candidate supply while we seek to secure another supplier that meets all regulatory requirements.

Reliance on third-party manufacturers entails risks to which we would not be subject if we manufactured product candidates ourselves, including:

Any of these factors could result in delays or higher costs in connection with our clinical trials, regulatory submissions, required approvals or commercialization of ibrexafungerp and any future product candidates we may seek to develop.

If we fail to establish or lose our relationships with CROs, our drug development efforts could be delayed.

We are substantially dependent on third-party vendors and CROs for preclinical studies and clinical trials related to our drug discovery and development efforts. If we fail to establish or lose our relationship with any one or more of these providers, we could experience a significant delay in both identifying another comparable provider and then contracting for its services, which could adversely affect our development efforts. We may be unable to retain an alternative provider on reasonable terms, or at all. Even if we locate an alternative provider, it is likely that this provider will need additional time to respond to our needs and may not provide the same type or level of services as the original provider. In addition, any contract research organization that we retain will be subject to the FDA’s regulatory requirements and similar foreign standards and we do not have control over compliance with these regulations by these providers. Consequently, if these practices and standards are not adhered to by

these providers, the development and commercialization of ibrexafungerp and any future product candidates we may seek to develop could be delayed, which could severely harm our business and financial condition.

We were dependent on Merck for the establishment of our intellectual property rights related to ibrexafungerp, and if Merck did not establish our intellectual property rights with sufficient scope to protect ibrexafungerp, we may have limited or no ability to assert intellectual property rights to ibrexafungerp.

Under our agreement with Merck, Merck was responsible for establishing the intellectual property rights to ibrexafungerp. As we were not responsible for the establishment of our intellectual property rights to ibrexafungerp, we have less visibility into the strength of our intellectual property rights to ibrexafungerp than if we had been responsible for the establishment of these rights. If Merck did not establish those rights such that they are of sufficient scope to protect ibrexafungerp, then we may not be able to prevent others from using or commercializing ibrexafungerp, and others may be able to assert intellectual property rights in ibrexafungerp and prevent us from further pursuing the development and commercialization of ibrexafungerp. Further, GSK has prosecution and enforcement rights for this IP and, if GSK does not determine to pursue prosecution and enforcement of intellectual property, the value of this intellectual property may diminish or be lost.

It is difficult and costly to protect our proprietary rights, and we may not be able to ensure their protection.

Our commercial success will depend in part on obtaining and maintaining patent protection and trade secret protection of ibrexafungerp and any future product candidates we may seek to develop and the methods used to manufacture them, as well as successfully defending these patents against third-party challenges. Our ability to stop third parties from making, using, selling, offering to sell or importing ibrexafungerp and any future product candidates we may seek to develop is dependent upon the extent to which we have rights under valid and enforceable patents or trade secrets that cover these activities.

The patent positions of pharmaceutical companies can be highly uncertain and involve complex legal and factual questions for which important legal principles remain unresolved. No absolute policy regarding the breadth of claims allowed in pharmaceutical patents has emerged to date in the United States or in many foreign jurisdictions. Changes in either the patent laws or in interpretations of patent laws in the United States and foreign jurisdictions may diminish the value of our intellectual property. Accordingly, we cannot predict the breadth of claims that may be enforced in the patents that we currently own or that may be issued from the applications we have filed or may file in the future or that we have licensed or may license from third parties, including Merck for ibrexafungerp. Further, if any patents we obtain or license are deemed invalid or unenforceable, it could impact our ability to commercialize or license our technology.

The degree of future protection for our proprietary rights is uncertain because legal means afford only limited protection and may not adequately protect our rights or permit us to gain or keep our competitive advantage. For example:

Due to the patent laws of a country, or the decisions of a patent examiner in a country, or our own filing strategies, we may not obtain patent coverage for all of the product candidates that may be disclosed or methods involving these candidates that may be disclosed in the parent patent application. We plan to pursue divisional patent applications and/or continuation patent applications in the United States and many other countries to obtain claim coverage for inventions that were disclosed but not claimed in the parent patent application, but may not succeed in these efforts.

Composition of matter patents on the active pharmaceutical ingredient are generally considered to be the strongest form of intellectual property protection for pharmaceutical products, as such patents generally provide protection without regard to any method of use. We cannot be certain that the claims in our patent applications covering composition-of-matter of our drug candidates will be considered patentable by the U.S. Patent and Trademark Office (USPTO) courts in the United States or by the patent offices and courts in foreign countries. Method of use patents protect the use of a product for the method recited in

the claims. This type of patent does not prevent a competitor from making and marketing a product that is identical to our product for an indication that is outside the scope of the patented method. Moreover, even if competitors do not actively promote their product for our targeted indications, physicians may prescribe these products “off-label.” Although off-label prescriptions may infringe or contribute to or induce the infringement of method of use patents, the practice is common and such infringement is difficult to prevent or prosecute. Interference or derivation proceedings provoked by third parties or brought by the USPTO may be necessary to determine the priority of inventions with respect to our patents or patent applications or those of our collaborators or licensors. An unfavorable outcome could require us to cease using the related technology or to attempt to license rights to it from the prevailing party. Our business could be harmed if the prevailing party does not offer us a license on commercially reasonable terms. Litigation, interference, or derivation proceedings may fail, resulting in harm to our business, and, even if successful, may result in substantial costs and distract our management and other employees.

We also rely on trade secrets to protect our technology, especially where we do not believe patent protection is appropriate or obtainable. However, trade secrets are difficult to protect. Although we use reasonable efforts to protect our trade secrets, our employees, consultants, contractors, licensees, licensors, outside scientific collaborators and other advisors may unintentionally or willfully disclose our information such that our competitors may obtain it. Enforcing a claim that a third party illegally obtained and is using any of our trade secrets is expensive and time consuming, and the outcome is unpredictable. Moreover, our competitors may independently develop equivalent knowledge, methods and know-how, such as new therapies, including therapies for the indications we are targeting. If others seek to develop similar therapies, their research and development efforts may inhibit our ability to conduct research in certain areas and to expand our intellectual property portfolio, and also have a material adverse effect on our business.

We may incur substantial costs as a result of litigation or other proceedings relating to patent and other intellectual property rights and we may be unable to enforce or protect our rights to, or use, our technology.

If we choose to go to court to stop another party from using the inventions claimed in any patents we obtain, that individual or company has the right to ask the court to rule that such patents are invalid or should not be enforced. These lawsuits are expensive and would consume time and resources and divert the attention of managerial and scientific personnel even if we were successful in stopping the infringement of such patents or sustaining their validity and enforceability. In addition, there is a risk that the court will decide that such patents are not valid or that we do not have the right to enforce them. There is also the risk that, even if the validity of such patents is upheld, the court will refuse to stop the other party on the grounds that such other party’s activities do not infringe such patents. In addition, the United States Court of Appeals for the Federal Circuit and the Supreme Court of the United States continue to address issues under the United States patent laws, and the decisions of those and other courts could adversely affect our ability to sustain the validity of our issued or licensed patents and obtain new patents.

Furthermore, a third party may claim that we or our manufacturing or commercialization partners or customers are using inventions covered by the third party’s patent rights and may go to court to stop us or our partners and/or customers from engaging in our operations and activities, including making or selling ibrexafungerp and any future product candidates we may seek to develop. These lawsuits are costly and could affect our results of operations and divert the attention of managerial and scientific personnel. There is a risk that a court would decide that we or our commercialization partners or customers are infringing the third party’s patents and would order us or our partners or customers to stop the activities covered by the patents. In that event, we or our commercialization partners or customers may not have a viable way around the patent and may need to halt commercialization or use of the relevant product. In addition, there is a risk that a court will order us or our partners or customers to pay the other party damages for having violated the other party’s patents or obtain one or more licenses from third parties, which may be impossible or require substantial time and expense. We cannot predict whether any license would be available at all or whether it would be available on commercially reasonable terms. Furthermore, even in the absence of litigation, we may need to obtain licenses from third parties to advance our research or allow commercialization of our drug candidates, and we have done so from time to time. We may fail to obtain any of these licenses at a reasonable cost or on reasonable terms, if at all. In such events, we would be unable to further develop and commercialize one or more of our drug candidates, which could harm our business significantly. In the future, we may agree to indemnify our commercial partners and/or customers against certain intellectual property infringement claims brought by third parties which could increase our financial expense, increase our involvement in litigation and/or otherwise materially adversely affect our business.

Because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation, which could adversely affect our intellectual property rights and our business. In addition, there could be public announcements of the results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on the price of our common stock.

The pharmaceutical and biotechnology industries have produced a proliferation of patents, and it is not always clear to industry participants, including us, which patents cover various types of products or methods of use. The coverage of patents is

subject to interpretation by the courts, and the interpretation is not always uniform. If we are sued for patent infringement, we would need to demonstrate that our products or methods either do not infringe the patent claims of the relevant patent or that the patent claims are invalid or unenforceable, and we may not be able to do this. Proving invalidity or unenforceability is difficult. For example, in the United States, proving invalidity requires a showing of clear and convincing evidence to overcome the presumption of validity enjoyed by issued patents.

Because some patent applications in the United States may be maintained in secrecy until the patents are issued, because patent applications in the United States and many foreign jurisdictions are typically not published until eighteen months after filing, because searches and examinations of patent applications by the USPTO and other patent offices may not be comprehensive, and because publications in the scientific literature often lag behind actual discoveries, we cannot be certain that others have not filed patent applications for technology covered by our patents or pending applications. Our competitors may have filed, and may in the future file, patent applications and may have obtained patents covering technology similar to ours. Any such patents or patent application may have priority over our patent applications, which could further require us to obtain or license rights to issued patents covering such technologies. If another party has obtained a U.S. patent or filed a U.S. patent application on inventions similar to ours, we may have to participate in a proceeding before the USPTO or in the courts to determine which patent or application has priority. The costs of these proceedings could be substantial, and it is possible that our application or patent could be determined not to have priority, which could adversely affect our intellectual property rights and business.

We have received confidential and proprietary information from collaborators, prospective licensees and other third parties. In addition, we employ individuals who were previously employed at other biotechnology or pharmaceutical companies. We may be subject to claims that we or our employees, consultants or independent contractors have improperly used or disclosed confidential information of these third parties or our employees’ former employers. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result in substantial cost and be a distraction to our management and employees. If we are not successful, our ability to continue our operations and our business could be materially, adversely affected.

Some of our competitors may be able to sustain the costs of complex intellectual property litigation more effectively than we can because they have substantially greater resources. In addition, any uncertainties resulting from the initiation and continuation of any litigation could have a material adverse effect on our ability to raise the funds necessary to continue our operations, on our ability to hire or retain employees, or otherwise on our business.

We may not be able to manage our business effectively if we are unable to attract and retain key personnel.

We may not be able to attract or retain qualified management, finance, scientific and clinical personnel in the future due to the intense competition for qualified personnel among biotechnology, pharmaceutical and other businesses. Stock-based awards are critical to our ability to recruit, retain and motivate highly skilled talent. However, the trading price of our common stock as listed on the Nasdaq Global Market has traded at or below the exercise price of a significant portion of the stock options currently held by our executive officers and key employees. This may reduce the retention value of these options and we may need to grant additional stock options, make further amendments to the terms of existing option awards, or provide alternative compensation and retention programs to continue to retain our employees, especially our key employees and executive officers. If we are not able to attract and retain necessary personnel to accomplish our business objectives, we may experience constraints that will significantly impede the achievement of our development objectives, our ability to raise additional capital and our ability to implement our business strategy. If we are unable to retain our current executive officers and key employees our ability to implement our business strategy successfully could be seriously harmed.

We may need to expand our operations and increase the size of our company, and we may experience difficulties in managing growth.

As of March 1, 2024, we had 29 full time employees. Further, as we advance ibrexafungerp and SCY-247 through preclinical studies, clinical trials and commercialization for other indications, we will need to increase our product development, scientific, marketing, sales and administrative headcount to manage these efforts. Our management, personnel and systems currently in place may not be adequate to support this future growth. Our need to effectively manage our operations, growth and various projects requires that we:

If we are unable to successfully manage this growth, our business may be adversely affected.

We may face potential product liability exposure, and if successful claims are brought against us, we may incur substantial liability for a product candidate and may have to limit its commercialization.

The use of product candidates in clinical trials and the sale of any products for which we may obtain marketing approval expose us to the risk of product liability claims. Product liability claims may be brought against us or our partners by participants enrolled in our clinical trials, patients, healthcare providers or others using, administering or selling products. If we cannot successfully defend ourselves against any such claims, we would incur substantial liabilities. Regardless of merit or eventual outcome, product liability claims may result in:

We have obtained limited product liability insurance coverage for our clinical trials domestically and in selected foreign countries where we are conducting clinical trials as required by local country regulations, in addition to limited product liability coverage for BREXAFEMME. Our coverage is currently limited to $25.0 million per occurrence and $25.0 million in the aggregate per year. As such, our insurance coverage may not reimburse us or may not be sufficient to reimburse us for any expenses or losses we may suffer. Moreover, insurance coverage is becoming increasingly expensive and, in the future, we may not be able to maintain insurance coverage at a reasonable cost or in sufficient amounts to protect us against losses due to product liability. We intend to expand our insurance coverage for products to include the sale of commercial products if we obtain marketing approval for product candidates, but we may be unable to obtain commercially reasonable product liability insurance for any products approved for marketing. Large judgments have been awarded in class action lawsuits based on drugs that had unanticipated side effects. A successful product liability claim or series of claims brought against us, particularly if judgments exceed our insurance coverage, could decrease our cash available to develop ibrexafungerp and any future product candidates we may seek to develop and adversely affect our business.

Our internal computer systems, or those used by our contract research organizations or other contractors or consultants, may fail or suffer security breaches.

Despite the implementation of security measures, our internal computer systems and those of our contract research organizations and other contractors and consultants are vulnerable to damage, data leakage and security breaches from computer viruses, unauthorized access, social engineering, the acts or omissions of our workforce or others with authorized access, natural disasters, terrorism, war and telecommunication and electrical failures. While we are not aware of the occurrence of any such system failure, accident or security breach to date, if such an event were to occur and cause interruptions in our or other contractors or consultants’ operations, it could result in a material disruption of our product candidate development programs. For example, the loss of clinical study data from completed or ongoing clinical studies for a product candidate could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. To the extent that any disruption or security breach was to result in a loss of or damage to our data or applications, or inappropriate disclosure of confidential or proprietary information, we could incur liability and the further development of any product candidates could be delayed.

Our insurance policies are expensive and protect us only from some business risks, which will leave us exposed to significant uninsured liabilities.

We do not carry insurance for all categories of risk that our business may encounter. Some of the policies we currently maintain include general liability, employment practices liability, property, auto, workers’ compensation, products liability and directors’ and officers’ insurance. We do not know, however, if we will be able to maintain existing insurance with adequate levels of coverage. Any significant uninsured liability may require us to pay substantial amounts, which would adversely affect our cash position and results of operations.

Our research and development activities could be affected or delayed as a result of possible restrictions on animal testing.

Certain laws and regulations require us to test our product candidates on animals before initiating clinical trials involving humans. Animal testing activities have been the subject of controversy and adverse publicity. Animal rights groups and other organizations and individuals have attempted to stop animal testing activities by pressing for legislation and regulation in these areas and by disrupting these activities through protests and other means. To the extent the activities of these groups are successful, our research and development activities may be interrupted, delayed or become more expensive.

We are subject to stringent and evolving U.S. and foreign laws, regulations, rules, contractual obligations, policies and other obligations related to data privacy and security. Our actual or perceived failure to comply with such obligations could lead to regulatory investigations or actions; litigation; fines and penalties; disruptions of our business operations; reputational harm; loss of revenue or profits; and other adverse business consequences.

In the ordinary course of business, we collect, receive, store, process, generate, use, transfer, disclose, make accessible, protect, secure, dispose of, transmit, and share confidential, proprietary, and sensitive information, including personal data, business data, trade secrets, intellectual property, information we collect about trial participants in connection with clinical trials, sensitive third-party data, business plans, transactions, and financial information.

Our data processing activities may subject us to numerous data privacy and security obligations, such as various laws, regulations, guidance, industry standards, external and internal privacy and security policies, contractual requirements, and other obligations relating to data privacy and security.

In the U.S., federal, state, and local governments have enacted numerous data privacy and security laws and regulations, including data breach notification laws, personal data privacy laws, consumer protection laws (e.g., Section 5 of the Federal Trade Commission Act), and other similar laws (e.g., wiretapping laws). For example, HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, and its implementing regulations, impose certain obligations with respect to safeguarding the privacy, security and transmission of individually identifiable health information on “covered entities,” such as certain healthcare providers, health plans, and healthcare clearinghouses and their respective “business associates” that perform services for them. In addition, in the past few years, numerous U.S. states—including California, Virginia, Colorado, Connecticut, and Utah—have enacted comprehensive data privacy and security laws that impose certain obligations on covered businesses, including providing specific disclosures in privacy notices and affording residents with certain rights concerning their personal data. As applicable, such rights may include the right to access, correct, or delete certain personal data, and to opt-out of certain data processing activities, such as targeted advertising, profiling, and automated decision-making. The exercise of these rights may impact our business and ability to provide our products and services. Certain states also impose stricter requirements for processing certain personal data, including sensitive information, such as conducting data privacy impact assessments. These state laws allow for statutory fines for noncompliance. For example, the California Consumer Privacy Act of 2018 (CCPA), as amended by the California Privacy Rights Act of 2020, applies to personal data of consumers, business representatives, and employees, and requires businesses to provide specific disclosures in privacy notices and honor requests of California residents to exercise certain privacy rights. The CCPA provides for civil penalties for violations of up to $7,500 per violation, as well as a private right of action for individuals impacted by certain data breaches. The CCPA and other comprehensive state data privacy and security laws exempt some data processed in the context of clinical trials, but these developments may further complicate compliance efforts, and increase legal risk and compliance costs for us, the third parties upon whom we rely.

Similar laws are being considered in several other states, as well as at the federal and local levels, and we expect more states to pass similar laws in the future. These developments may further complicate compliance efforts, and increase legal risk and compliance costs for us and the third parties upon whom we rely.

Outside the U.S., an increasing number of laws, regulations, and industry standards may govern data privacy and security, including information that we collect about patients in connection with clinical trials and our other operations abroad. For example, the EU’s General Data Protection Regulation (EU GDPR) and the United Kingdom’s GDPR (UK GDPR) impose strict requirements for processing personal data, including health-related information. For example, under the EU GDPR, companies may face temporary or definitive bans on data processing and other corrective actions; fines of up to the greater of 20 million euros or 4% of annual global revenue, whichever is greater; or private litigation related to processing of personal data brought by classes of data subjects or consumer protection organizations authorized at law to represent their interests.

In addition, we may be unable to transfer personal data from Europe and other jurisdictions to the United States or other countries due to data localization requirements or limitations on cross-border data flows. Europe and other jurisdictions have enacted laws requiring data to be localized or limiting the transfer of personal data to other countries. In particular, the European Economic Area (EEA) and the United Kingdom (UK) have significantly restricted the transfer of personal data to the United States and other countries whose data privacy and security laws they believe are inadequate. Other jurisdictions may adopt similarly stringent interpretations of their data localization and cross-border data transfer laws. Although there are

currently various mechanisms that may be used to transfer personal data from the EEA and UK to the United States in compliance with law, such as the EEA standard contractual clauses, the UK’s International Data Transfer Agreement / Addendum, and the EU-U.S. Data Privacy Framework and the UK extension thereto (which allows for transfers to relevant U.S.-based organizations who self-certify compliance and participate in the Framework), these mechanisms are subject to legal challenges, and there is no assurance that we can satisfy or rely on these measures to lawfully transfer personal data to the United States. If there is no lawful manner for us to transfer personal data from the EEA, the UK, or other jurisdictions to the United States, or if the requirements for a legally-compliant transfer are too onerous, we could face significant adverse consequences, including the interruption or degradation of our operations, the need to relocate part of or all of our business or data processing activities to other jurisdictions at significant expense, increased exposure to regulatory actions, substantial fines and penalties, the inability to transfer data and work with partners, vendors and other third parties, and injunctions against our processing or transferring of personal data necessary to operate our business. Additionally, companies that transfer personal data out of the EEA and UK to other jurisdictions, particularly to the United States, are subject to increased scrutiny from regulators, individual litigants, and activities groups. Some European regulators have ordered certain companies to suspend or permanently cease certain transfers of personal data out of Europe for allegedly violating the EU GDPR’s cross-border data transfer limitations.

In addition to data privacy and security laws, we are or may become contractually subject to industry standards adopted by industry groups and may become subject to such obligations in the future. We are also bound by other contractual obligations related to data privacy and security, and our efforts to comply with such obligations may not be successful.

We publish privacy policies, marketing materials, and other statements, such as compliance with certain certifications or self-regulatory principles, regarding data privacy and security. If these policies, materials or statements are found to be deficient, lacking in transparency, deceptive, unfair, or misrepresentative of our practices, we may be subject to investigation, enforcement actions by regulators, or other adverse consequences.

Obligations related to data privacy and security are quickly changing, becoming increasingly stringent, and creating regulatory uncertainty. Additionally, these obligations may be subject to differing applications and interpretations, which may be inconsistent or conflict among jurisdictions. Preparing for and complying with these obligations requires us to devote significant resources and may necessitate changes to our services, information technologies, systems, and practices and to those of any third parties that process personal data on our behalf.

We may at times fail (or be perceived to have failed) in our efforts to comply with our data privacy and security obligations. Moreover, despite our efforts, our personnel or third parties on whom we rely may fail to comply with such obligations, which could negatively impact our business operations. If we or the third parties on which we rely fail, or are perceived to have failed, to address or comply with applicable data privacy and security obligations, we could face significant consequences, including but not limited to: government enforcement actions (e.g., investigations, fines, penalties, audits, inspections, and similar); litigation (including class-action claims); additional reporting requirements and/or oversight; bans on processing personal data; and orders to destroy or not use personal data. Any of these events could have a material adverse effect on our reputation, business, or financial condition, including but not limited to: loss of customers; inability to process personal data or to operate in certain jurisdictions; limited ability to develop or commercialize our products; expenditure of time and resources to defend any claim or inquiry; adverse publicity; or substantial changes to our business model or operations.

If our information technology systems or data, or those of third parties upon which we rely, are or were compromised, we could experience adverse consequences resulting from such compromise, including but not limited to regulatory investigations or actions; litigation; fines and penalties; disruptions of our business operations; reputational harm; loss of revenue or profits; and other adverse consequences.

In the ordinary course of our business, we and the third parties upon which we rely process confidential, proprietary, and sensitive data, and, as a result, we and the third parties upon which we rely face a variety of evolving threats, including but not limited to ransomware attacks, which could cause security incidents. Cyber-attacks, malicious internet-based activity, online and offline fraud, and other similar activities threaten the confidentiality, integrity, and availability of our confidential, proprietary, and sensitive data and information technology systems, and those of the third parties upon which we rely. Such threats are prevalent and continue to rise, are increasingly difficult to detect, and come from a variety of sources, including traditional computer “hackers,” threat actors, “hacktivists,” organized criminal threat actors, personnel (such as through theft or misuse), sophisticated nation states, and nation-state-supported actors.

Some actors now engage and are expected to continue to engage in cyber-attacks, including without limitation nation-state actors for geopolitical reasons and in conjunction with military conflicts and defense activities. During times of war and other major conflicts, we and the third parties upon which we rely may be vulnerable to a heightened risk of these attacks, including retaliatory cyber-attacks, that could materially disrupt our systems and operations, supply chain, and ability to produce, sell and distribute our services.

We and the third parties upon which we rely are subject to a variety of evolving threats, including but not limited to social-engineering attacks (including through deep fakes, which may be increasingly more difficult to identify as fake, and phishing attacks), malicious code (such as viruses and worms), malware (including as a result of advanced persistent threat intrusions), denial-of-service attacks, credential stuffing attacks, credential harvesting, personnel misconduct or error, ransomware attacks, supply-chain attacks, software bugs, server malfunctions, software or hardware failures, loss of data or other information technology assets, adware, attacks enhanced or facilitated by AI, telecommunications failures, earthquakes, fires, floods, and other similar threats.

In particular, severe ransomware attacks are becoming increasingly prevalent and can lead to significant interruptions in our operations, loss of confidential, proprietary, and sensitive data and income, reputational harm, and diversion of funds. Extortion payments may alleviate the negative impact of a ransomware attack, but we may be unwilling or unable to make such payments due to, for example, applicable laws or regulations prohibiting such payments.

Remote work has become more common and has increased risks to our information technology systems and data, as more of our employees utilize network connections, computers, and devices outside our premises or network, including working at home, while in transit and in public locations. Additionally, future or past business transactions (such as acquisitions or integrations) could expose us to additional cybersecurity risks and vulnerabilities, as our systems could be negatively affected by vulnerabilities present in acquired or integrated entities’ systems and technologies. Furthermore, we may discover security issues that were not found during due diligence of such acquired or integrated entities, and it may be difficult to integrate companies into our information technology environment and security program.

In addition, our reliance on third-party service providers could introduce new cybersecurity risks and vulnerabilities, including supply-chain attacks, and other threats to our business operations. We rely on third-party service providers and technologies to operate critical business systems to process confidential, proprietary, and sensitive data in a variety of contexts, including, without limitation, CROs, CMOs, cloud-based infrastructure, data center facilities, encryption and authentication technology, employee email, content delivery to customers, and other functions. We also rely on third-party service providers to provide other products, services, parts, or otherwise to operate our business. Our ability to monitor these third parties’ information security practices is limited, and these third parties may not have adequate information security measures in place. If our third-party service providers experience a security incident or other interruption, we could experience adverse consequences. While we may be entitled to damages if our third-party service providers fail to satisfy their privacy or security-related obligations to us, any award may be insufficient to cover our damages, or we may be unable to recover such award. In addition, supply-chain attacks have increased in frequency and severity, and we cannot guarantee that third parties’ infrastructure in our supply chain or our third-party partners’ supply chains have not been compromised.

Any of the previously identified or similar threats could cause a security incident or other interruption that could result in unauthorized, unlawful, or accidental acquisition, modification, destruction, loss, alteration, encryption, disclosure of, or access to our confidential, proprietary, and sensitive data or our information technology systems, or those of the third parties upon whom we rely. A security incident or other interruption could disrupt our ability (and that of third parties upon whom we rely) to provide our services.

We may expend significant resources or modify our business activities to try to protect against security incidents. Additionally, certain data privacy and security obligations may require us to implement and maintain specific security measures or industry-standard or reasonable security measures to protect our information technology systems and confidential, proprietary, and sensitive data.

While we have implemented security measures designed to protect against security incidents, there can be no assurance that these measures will be effective. We take steps to detect and remediate vulnerabilities, in our information systems (such as our hardware and/or software, including that of third parties upon which we rely). We may not detect and remediate all such vulnerabilities including in a timely manner. Further, we may experience delays in developing and deploying remedial measures and patches designed to address identified vulnerabilities. Vulnerabilities could be exploited and result in a security incident.

Applicable data privacy and security obligations may require us to notify relevant stakeholders, such as governmental authorities, partners, and affected individuals, of security incidents. Such disclosures may involve inconsistent requirements and are costly, and the disclosure or the failure to comply with such requirements could lead to adverse consequences.

If we (or a third party upon whom we rely) experience a security incident or are perceived to have experienced a security incident, we may experience adverse consequences, such as government enforcement actions (for example, investigations, fines, penalties, audits, and inspections); additional reporting requirements and/or oversight; restrictions on processing confidential, proprietary, and sensitive data (including personal data); litigation (including class claims); indemnification obligations; negative publicity; reputational harm; monetary fund diversions; diversion of management’s attention; interruptions in our operations (including availability of data); financial loss; and other similar harms. Security

incidents and attendant consequences may cause customers to stop using our services, deter new customers from using our services, and negatively impact our ability to grow and operate our business.

Our contracts may not contain limitations of liability, and even where they do, there can be no assurance that limitations of liability in our contracts are sufficient to protect us from liabilities, damages, or claims related to our data privacy and security obligations. We cannot be sure that our insurance coverage will be adequate or sufficient to protect us from or to mitigate liabilities arising out of our privacy and security practices, that such coverage will continue to be available on commercially reasonable terms or at all, or that such coverage will pay future claims.

In addition to experiencing a security incident, third parties may gather, collect, or infer sensitive information about us from public sources, data brokers, or other means that reveals competitively sensitive details about our organization and could be used to undermine our competitive advantage or market position.

The trading price of our common stock may be volatile. The following factors, in addition to other factors described in this “Risk Factors” section and elsewhere in this report, may have a significant impact on the market price of our common stock:

In addition, companies trading in the stock market in general, and the Nasdaq Global Market in particular, have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of these companies. Broad market and industry factors may negatively affect the market price of our common stock, regardless of our actual operating performance.

Future sales and issuances of our common stock or rights to purchase common stock could result in additional dilution of the percentage ownership of our stockholders and could cause our stock price to fall.

We expect that significant additional capital will be needed in the future to continue our planned operations. To the extent we raise additional capital by issuing equity securities, our stockholders may experience substantial dilution. We may sell common stock, convertible securities or other equity securities in one or more transactions at prices and in a manner we determine from time to time. These sales may also result in new investors gaining rights superior to our existing stockholders. For example, in March 2019, we issued and sold $16 million of 6.0% convertible senior notes. The holders may convert their convertible notes at their option at any time prior to the close of business on the business day immediately preceding March 15, 2025. Upon conversion of the convertible notes by a holder, the holder will receive shares of our common stock, together, if applicable, with cash in lieu of any fractional share. Holders who convert may also be entitled to receive, under certain circumstances, an interest make-whole payment payable in shares of common stock. In addition, following certain corporate events that occur prior to the maturity date, we will, in certain circumstances, increase the conversion rate for a holder who elects to convert its convertible notes in connection with such a corporate event. To the extent holders of these notes convert the notes, our stockholders may experience substantial dilution. Additionally, the holders of our outstanding warrants also may exercise their right to buy our common stock which could result in additional dilution to our stockholders.

Anti-takeover provisions in our charter documents and under Delaware law could make an acquisition of us, which may be beneficial to our stockholders, more difficult and may prevent attempts by our stockholders to replace or remove our current management.

Provisions in our amended and restated certificate of incorporation and our bylaws may delay or prevent an acquisition of us, including the ability of our board of directors to establish new series of preferred stock and issue shares of these new series, which could be used by our board of directors to oppose a hostile takeover attempt, which some stockholders may believe would be in the best interests of stockholders. In addition, these provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our board of directors, which is responsible for appointing the members of our management, including the elimination of cumulative voting, inability of our stockholders to call special meetings or take action by written consent, ability of our board of directors to fill board vacancies, and ability of our board of directors to determine the size of the board of directors. In addition, we are subject to Section 203 of the Delaware General Corporation Law, which generally prohibits stockholders owning in excess of 15% of our outstanding voting stock from merging or combining with us. Finally, our charter documents establish advance notice requirements for nominations for election to our board of directors and for proposing matters that can be acted upon at stockholder meetings. Although we believe these provisions together provide for an opportunity to receive higher bids by requiring potential acquirers to negotiate with our board of directors, they would apply even if the offer may be considered beneficial by some stockholders.

Our business could be adversely affected by the continuation of the exposure to COVID-19, in regions where we or third parties on which we rely have significant concentrations of clinical trial sites, manufacturing facilities, or other business operations. We have a significant number of clinical trial sites in countries that have been directly affected by COVID-19, and depend on manufacturing operations for various stages of our supply chain in countries affected by COVID-19. The ultimate impact of COVID-19 is highly uncertain and subject to change. We do not yet know the full extent of potential delays or impacts on our business, our clinical trials, our activities dependent on regulatory authorities, healthcare systems or the global economy as a whole. However, these effects could have a material impact on our operations, and we will continue to monitor the COVID-19 situation closely.

We have implemented and maintain various information security processes designed to identify, assess and manage material risks from cybersecurity threats to our critical computer networks, third party hosted services, and our critical data, including intellectual property, confidential information that is proprietary, strategic or competitive in nature such as data about our research and clinical trials (“Information Systems and Data”).

Our information security function, which includes our information technology Managed Service Provider (MSP), helps identify, assess and manage the Company’s cybersecurity threats and risks. We identify and assess risks from cybersecurity threats by monitoring and evaluating our threat environment using various methods including: manual and automated tools; subscribing to and analyzing reports and services that identify cybersecurity threats; evaluating threats reported to us; and conducting vulnerability assessments.

Depending on the environment, systems, and data, we implement and maintain various technical, physical, and organizational measures, processes, standards and policies designed to manage and mitigate material risks from cybersecurity threats to our Information Systems and Data, including, for example: an incident response process; disaster recovery/business continuity plans; encrypting certain data; using network security controls; maintaining access controls; managing assets; and maintaining cybersecurity insurance.

Our assessment and management of material risks from cybersecurity threats are integrated into the Company’s overall risk management processes. For example, (1) cybersecurity risk is addressed as a component of the Company’s enterprise risk management program; (2) we prioritize our risk management processes to include mitigation of risks from cybersecurity threats that are more likely to lead to a material impact to our business; (3) management evaluates material risks from cybersecurity threats against our overall business objectives and reports to the Audit Committee, which evaluates our overall enterprise risk.

We use third-party service providers to assist us from time to time to identify, assess, and manage material risks from cybersecurity threats, including for example our information technology MSP.

We use third-party service providers to perform a variety of functions throughout our business, such as distributors and supply chain resources and contract research organizations (CRO) and contract manufacturing organizations (CMO). We have certain vendor management processes to manage cybersecurity risks associated with our use of certain providers, depending on the nature of the services provided, the sensitivity of the Information Systems and Data at issue, and the identity of the provider. These processes may include information security questionnaires, assessments, and imposition of contractual obligations relating to cybersecurity.

We have not identified any cybersecurity incidents or threats that have materially affected us or are reasonably likely to materially affect us. For a description of the risks from cybersecurity threats that may materially affect the Company and how they may do so, see our risk factors under Part I. Item 1A. Risk Factors in this Annual Report on Form 10-K, including “If our information technology systems or data, or those of third parties upon which we rely, are or were compromised, we could experience adverse consequences resulting from such compromise, including but not limited to regulatory investigations or actions; litigation; fines and penalties; disruptions of our business operations; reputational harm; loss of revenue or profits; and other adverse consequences.”

Our board of directors, through its Audit Committee, is responsible for overseeing Company’s cybersecurity risk management processes, including oversight of mitigation of risks from cybersecurity threats.

On March 1, 2018, we entered into a long-term lease agreement for approximately 19,275 square feet of office space in Jersey City, New Jersey. The lease term is until July 2029, and we have the option to renew for two consecutive five-year periods from the end of the first term. We believe that our facilities under this lease are adequate for our purposes for the foreseeable future.

ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

Our common stock trades on the Nasdaq Global Market under the symbol “SCYX.”

As of March 1, 2024, there were approximately 43 stockholders of record of our common stock, which excludes stockholders whose shares were held in nominee or street name by brokers. The actual number of common stockholders is greater than the number of record holders, and includes stockholders who are beneficial owners, but whose shares are held in street name by brokers and other nominees. This number of holders of record also does not include stockholders whose shares may be held in trust by other entities.

We have never declared or paid any cash dividends on our common stock. We currently intend to retain all available funds and any future earnings to support our operations and finance the growth and development of our business. We do not intend to pay cash dividends on our common stock for the foreseeable future. Any future determination related to our dividend policy will be made at the discretion of our board of directors and will depend upon, among other factors, our results of operations, financial condition, capital requirements, contractual restrictions, business prospects and other factors our board of directors may deem relevant.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Operating results for the year ended December 31, 2023, are not necessarily indicative of results that may occur in future fiscal years. Some of the statements in this “Management’s Discussion and Analysis of Financial Condition and Results of Operations” are forward-looking statements. These forward-looking statements are based on management’s beliefs and assumptions and on information currently available to our management and involve significant elements of subjective judgment and analysis. Words such as “expects,” “will,” “anticipates,” “targets,” “intends,” “plans,” “believes,” “seeks,” “estimates,” “potential,” “should,” “could,” variations of such words, and similar expressions are intended to identify forward-looking statements. Our actual results and the timing of events may differ significantly from the results discussed in the forward-looking statements. Factors that might cause such a difference include those discussed under the caption “Special Note Regarding Forward Looking Statements” and in “Risk Factors” and elsewhere in this Annual Report on Form 10-K. These and many other factors could affect our future financial and operating results. We undertake no obligation to update any forward-looking statement to reflect events after the date of this Annual Report.

SCYNEXIS, Inc. is pioneering innovative medicines to overcome and prevent difficult-to-treat and drug-resistant infections. We are developing our proprietary antifungal platform “fungerps”, a novel class of antifungal agents called triterpenoids, that are a structurally distinct glucan synthase inhibitors and have generally shown in vitro and in vivo activity against a broad range of human fungal pathogens such as Candida and Aspergillus genera, including multidrug-resistant strains, as well as Pneumocystis, Coccidioides, Histoplasma and Blastomyces genera and most common mucorales species.

SCY-247, a second-generation antifungal compound from this novel class, is in preclinical development stage. We anticipate initiating a Phase 1 study for SCY-247 in the second half of 2024.

On March 30, 2023, we entered into a license agreement (the GSK License Agreement) with GlaxoSmithKline Intellectual Property (No. 3) Limited (GSK). Pursuant to the terms of the GSK License Agreement, we granted GSK an exclusive (even as to us and our affiliates), royalty-bearing, sublicensable license for the development, manufacture, and commercialization of ibrexafungerp, including the approved product BREXAFEMME, for all indications, in all countries other than those in the Greater China region and certain other countries already licensed to third parties (the GSK Territory). The parties closed the GSK License Agreement in May 2023 and we received an upfront payment of $90.0 million. In June 2023, we announced the achievement of a $25.0 million performance-based development milestone under the GSK License Agreement. This milestone payment followed a development goal for the Phase 3 MARIO study for ibrexafungerp in IC as we continued executing ongoing ibrexafungerp trials.

On December 26, 2023, we and GSK entered into a binding memorandum of understanding (Binding MOU) for amendment to the GSK License Agreement. The GSK License Agreement is being amended in connection with the delay in the commercialization of BREXAFEMME (see "Product Recall and Clinical Hold" section) and further clinical development of ibrexafungerp associated with this event. Under the terms of the updated GSK License Agreement, as amended by the Binding MOU, we are eligible to receive potential:

These milestones are based on annual net sales in the GSK Territory, with a total of $64 / $54.25 / $46.5 million to be paid upon achievement of multiple sales thresholds up through $200 million; a total of $45.5 / $45.5 / $39 million to be paid upon achievement of multiple sales thresholds between $300 million and $500 million; and $35 / $35 / $30 million to be paid at each sales threshold of $750 million and $1 billion.

Following a review by GSK of the manufacturing process and equipment at the vendor that manufactures the ibrexafungerp drug substance, we became aware that a non-antibacterial beta-lactam drug substance was manufactured using equipment common to the manufacturing process for ibrexafungerp. Current FDA draft guidance recommends segregating the manufacture of non-antibacterial beta-lactam compounds from other compounds since beta-lactam compounds have the potential to act as sensitizing agents that may trigger hypersensitivity or an allergic reaction in some people. In the absence of the recommended segregation, there is a risk of cross contamination. It is not known whether any ibrexafungerp has been contaminated with a beta-lactam compound and we have not received any reports of adverse events due to the possible beta-lactam cross contamination. Nonetheless, out of an abundance of caution and in line with GSK’s recommendation, we have recalled BREXAFEMME (ibrexafungerp tablets) from the market and placed a temporary hold on clinical studies of ibrexafungerp, including the Phase 3 MARIO study.

The primary objective of the study is to determine whether treatment of IC with IV echinocandins followed by oral ibrexafungerp is as effective as treatment with IV echinocandins followed by oral fluconazole (or BAT), the current standard of care. The primary end point of the study will be all-cause mortality at 30 days after initiation of antifungal therapy. The data from MARIO study is intended to be supportive of an NDA submission for ibrexafungerp as step-down therapy in patients with IC. Such submission would be made by GSK and any resulting approval would be held by GSK.

Based on promising preclinical data from combination use of ibrexafungerp with voriconazole, the current standard of care, vs. Aspergillus spp., a Phase 2 study (SCYNERGIA study) of oral ibrexafungerp in combination with voriconazole in patients with IA was conducted. This study is a randomized, double-blind trial with the objective of assessing the safety and efficacy of oral ibrexafungerp in combination with voriconazole, compared to voriconazole alone. We completed enrollment with 22 patients included and the data analysis is ongoing. We expect to provide topline data for the SCYNERGIA study to GSK in the first half of 2024.

We have completed the enrollment of the VANQUISH Phase 3b open-label trial evaluating the safety and efficacy of ibrexafungerp in 150 patients with complicated vulvovaginal candidiasis who failed to respond to treatment with fluconazole. We expect to provide topline data for the VANQUISH study to GSK in the first half of 2024.

We, Hercules Capital, Inc. (Hercules Capital) and Silicon Valley Bridge Bank, N.A. (as successor to Silicon Valley Bank) (SVBB) were parties to a Loan and Security Agreement dated as of May 13, 2021 (the Loan Agreement), pursuant to which Hercules Capital, SVBB and each of the other lenders from time-to-time party to the Loan Agreement (collectively, the Lenders) loaned to us $35 million. In connection with the entering into of the GSK License Agreement, we entered into a First Amendment and Consent to Loan and Security Agreement with the Lenders pursuant to which the Lenders consented to us entering into the GSK License Agreement and we agreed to pay to the Lenders an amount equal to the sum of (i) all outstanding principal plus all accrued and unpaid interest with respect to the amounts loaned under the Loan Agreement (approximately $35.4 million), (ii) the prepayment fee payable under Loan Agreement ($262,500), (iii) the final payment payable under Loan Agreement ($1,382,500), and (iv) all other sums, if any, that shall have become due and payable with respect to loan advances under the Loan Agreement. These payments became due upon the earliest of (A) one business day following receipt by us of the $90 million upfront payment payable to us under the GSK License Agreement, (B) June 1, 2023, or (C) the termination of the GSK License Agreement.

Following the closing of the transactions under the GSK License Agreement, in May 2023, we received the upfront payment pursuant to the terms of the GSK License Agreement, which triggered the obligation of us to repay the amounts due under the terms of the First Amendment. In connection with the repayment of those amounts due, in May 2023, we and the Lenders executed a payoff letter confirming the amounts due under the First Amendment, and our confirmation that the Loan Agreement, as amended by the First Amendment, was terminated.

We continue progressing development activities for SCY-247. SCY-247 is a broad-spectrum antifungal with a potential oral and IV systemic therapeutic option for multiple drug-resistant pathogens. Some of these activities, including assessing the activity of the compound against Candida auris and Mucorales are being supported by NIH grants. We anticipate initiating a Phase 1 study for SCY-247 in the second half of 2024.

We have operated as a public entity since we completed our initial public offering in May 2014, which we refer to as our IPO. We also completed a follow-on public offering of our common stock in April 2015 and public offerings of our common stock and warrants in June 2016, March 2018, December 2019, December 2020, and April 2022. Our principal source of liquidity is cash, cash equivalents, and investments which totaled $98.0 million as of December 31, 2023.

As of December 31, 2023, our accumulated deficit was $355.2 million. We expect we will continue to incur significant research and development expense as we continue to execute our research and drug development strategy. We also expect that we will continue to incur significant selling, general and administrative expenses to support our public reporting company operations and ongoing operations. As a result, we will need additional capital to fund our operations, which we may obtain through one or more of equity offerings, debt financings, other non-dilutive third-party funding (e.g., grants), strategic alliances and licensing or collaboration arrangements. We may offer shares of our common stock pursuant to our effective shelf registration statements.

Revenue consists of license agreement revenue associated with GSK and Hansoh and product sales of BREXAFEMME. Our product revenue, net comprised of sales of BREXAFEMME that we sold as principal given we control BREXAFEMME product until delivery to our wholesalers at which point control is transferred.

Cost of product revenue consists primarily of inventory impairment expense, distribution, freight expenses, royalties due to Merck, and other manufacturing costs associated with BREXAFEMME.

Research and development expense consists of expenses incurred while performing research and development activities to discover, develop, or improve potential product candidates we seek to develop. This includes conducting preclinical studies and clinical trials, manufacturing and other development efforts, and activities related to regulatory filings for product candidates. We recognize research and development expenses as they are incurred. Our research and development expense primarily consists of:

Ibrexafungerp and SCY-247 were the only key research and development projects during the periods presented. We expect to continue to incur significant research and development expense for the foreseeable future as we continue our effort to develop ibrexafungerp and SCY-247, and to potentially develop our other product candidates, subject to the availability of additional funding.

The successful development of product candidates is highly uncertain. At this time, we cannot reasonably estimate the nature, timing or costs required to complete the remaining development of any product candidates. This is due to the numerous risks and uncertainties associated with the development of product candidates.

Selling, general and administrative expense consists primarily of salaries and personnel-related costs, including employee benefits and any stock-based compensation. This includes personnel in executive, accounting and finance, commercial, human resources, business development, and administrative support functions. Other expenses include facility-related costs not otherwise allocated to research and development expense, professional fees for accounting, auditing, tax and legal services, consulting costs for general and administrative purposes, information systems maintenance and marketing efforts.

Substantially all of our other expense (income) during the periods reported consists of costs associated with:

To date, we have not been required to pay U.S. federal income taxes because of our current and accumulated net operating losses. For the years ended December 31, 2023 and 2022, our income tax (expense) benefit recognized consists primarily of an income tax expense for state taxes and an income tax benefit associated with the sale of our NOLs and research and development credits, respectively.

The following table summarizes our results of operations for the years ended December 31, 2023 and 2022, and period-to-period percentage change (dollars in thousands):

Revenue. For the year ended December 31, 2023, revenue primarily consists of the $130.1 million recognized upon the transfer of the license associated with the GSK License Agreement in May 2023 and $4.4 million in license agreement revenue recognized as part of the Binding MOU. For the year ended December 31, 2022, revenues primarily consists of product sales of BREXAFEMME.

Cost of Product Revenues. For the year ended December 31, 2023, cost of product revenue consists primarily of the $14.5 million in impairment expense recognized in the period in addition to distribution, freight, and royalty costs associated with BREXAFEMME. For the year ended December 31, 2022, cost of product revenue consists primarily of distribution, freight, and royalty costs associated with BREXAFEMME.

Research and Development. For the year ended December 31, 2023, research and development expenses increased to $30.9 million from $27.3 million for the year ended December 31, 2022. The increase of $3.7 million, or 13.5%, was primarily driven by an increase of $2.6 million in clinical development expense, an increase of $0.5 million in preclinical expense, an increase of $0.4 million in chemistry, manufacturing, and controls (CMC) expense, and an increase of $0.5 million in salary expense primarily associated with medical affairs.

The $2.6 million increase in clinical development expense for the year ended December 31, 2023, was primarily driven by an increase of $1.8 million in expense associated with the costs for the MARIO study, an increase of $1.1 million in expense associated with the closing activities of the FURI, CARES, and SCYNERGIA studies, and an increase of $0.6 million associated with a Phase 1 study of oral ibrexafungerp which was substantially complete in the second quarter of 2023 and is intended to support the potential NDA filing for the treatment of IC, offset in part by a $1.3 million decrease in expense associated with the CANDLE Phase 3 study which was substantially complete in the first quarter of 2022. The $0.5 million increase in preclinical expense was primarily associated with the expense recognized for certain preclinical studies associated with SCY-247. The $0.4 million increase in CMC expense for the year ended December 31, 2023, was primarily driven by increased costs associated with drug supply for SCY-247.

Selling, General and Administrative. For the year ended December 31, 2023, selling, general and administrative expenses decreased to $20.9 million from $63.0 million for the year ended December 31, 2022. The decrease of $42.0 million, or 66.8%, was primarily driven by a decrease of $33.5 million in commercial expense due to the costs incurred in the prior comparable period associated with the active promotion of BREXAFEMME which ceased in the fourth quarter of 2022, a decrease of $5.2 million in salary related primarily driven by the workforce reduction in the fourth quarter of 2022 concentrated in the commercial and medical affairs functions, a $2.8 million decrease associated with other medical affairs related expense, a $1.6 million decrease in severance expense primarily driven by the workforce reduction in the fourth quarter of 2022, a $1.5 million decrease in information technology expense, offset in part by an increase in professional fees of $2.0 million. The $2.0 million increase in professional fees is primarily due to a $3.1 million expense incurred during the current period for business development associated with the GSK License Agreement.

Amortization of Debt Issuance Costs and Discount. For the years ended December 31, 2023 and 2022, we recognized $3.0 million and $1.6 million in amortization of debt issuance costs and discount. The increase of $1.4 million, or 88%, was primarily driven by the recognition of $1.9 million in amortization during the year ended December 31, 2023 for the remaining debt issuance costs and discount associated with the loan payable with Hercules and SVBB which was fully paid in May 2023. The 2023 and 2022 debt issuance costs and discount for our March 2019 convertible notes primarily consisted of an allocated portion of advisory fees and other issuance costs and the initial fair value of the derivative liability.

Interest Income. For the years ended December 31, 2023 and 2022, we recognized $4.0 million and $1.4 million, respectively, in interest income associated with our money market accounts and investments. The increase in interest income was primarily due to the increase in the interest rates on our money market accounts and investments.

Interest Expense. For the years ended December 31, 2023 and 2022, we recognized $3.1 million and $5.2 million, respectively, in interest expense associated with our Loan Agreement and convertible debt. The decrease in interest expense was primarily due to the repayment of the Loan Agreement in May 2023.

Other Income. For the years ended December 31, 2023 and 2022, we recognized zero and $3,000 in other income associated with certain research and development tax credits.

Warrant Liabilities Fair Value Adjustment. For the years ended December 31, 2023 and 2022, we recognized a loss of $3.2 million and a gain of $22.3 million, respectively, for the fair value adjustment for warrant liabilities primarily due to the increase and decrease in our stock price during the periods, respectively.

Derivative Liabilities Fair Value Adjustment. For the years ended December 31, 2023 and 2022, we recognized a loss of $0.2 million and a gain of $1.3 million, respectively, in the fair value adjustment related to the derivative liability primarily due to the increase and decrease in our stock price during the periods, respectively.

Income Tax Expense (Benefit). For the year ended December 31, 2023, we recognized $0.1 million in income tax expense primarily for state income taxes. For the year ended December 31, 2022, we recognized a $4.7 million income tax benefit associated with the sale of a portion of our NOLs and research and development credits.

As of December 31, 2023, we had cash, cash equivalents, and investments of approximately $98.0 million, compared to cash, cash equivalents, and investments of $73.5 million as of December 31, 2022. The increase in our cash and cash equivalents and investments was primarily due to the $90.0 million upfront receipt from the closing of the GSK License Agreement and the receipt of a $25.0 million performance-based development milestone under the GSK License Agreement, offset in part by the $37.0 million repayment in full of our Loan Agreement, the continued development costs associated with ibrexafungerp and SCY-247, and the payment of the deferred fees associated with Amplity, Inc. (Amplity). We believe our capital resources are sufficient to fund our on-going operations for a period of at least 12 months subsequent to the issuance of the accompanying consolidated financial statements.

As of December 31, 2023, our accumulated deficit was $355.2 million. We anticipate that we will continue to incur losses for at least the next several years. As a result, we will need additional capital to fund our operations, which we may obtain through one or more of equity offerings, debt financings, or other non-dilutive third-party funding (e.g., grants), strategic alliances and licensing or collaboration arrangements.

The following table sets forth the significant sources and uses of cash for the years ended December 31, 2023 and 2022 (dollars in thousands):

The $140.0 million increase in net cash provided by operating activities for the year ended December 31, 2023, as compared to the year ended December 31, 2022, was primarily due to the $90.0 million upfront receipt upon the closing of the GSK License Agreement and the receipt of a $25.0 million performance-based development milestone under the GSK License Agreement, offset by the continued development costs associated with ibrexafungerp and SCY-247.

Net cash provided by operating activities of $60.2 million for the year ended December 31, 2023, primarily consisted of the $67.0 million net income adjusted for non-cash charges that included the loss on change in fair value of the warrant liabilities of $3.2 million, stock-based compensation expense of $2.6 million, accretion of investment discount of $1.3 million, the loss on change in fair value of the derivative liability of $0.2 million, and the amortization of debt issuance costs and discount of $3.0 million, plus a net unfavorable change in operating assets and liabilities of $30.6 million. The net unfavorable change in operating assets and liabilities was due to a net decrease in operating liabilities of $0.9 million and by a net increase of $31.5 million in operating assets. The net increase of $31.5 million in operating assets is primarily due to a $19.3 million increase in license agreement contract asset associated with the GSK License Agreement, an increase in license agreement receivable of $2.5 million, and an increase of $4.4 million in unbilled receivable due from GSK associated with the Binding MOU. The $0.9 million increase in operating liabilities was primarily due to an increase of $1.2 million in accounts payable and a decrease in accrued expenses, deferred revenue, other liabilities, and other of $0.3 million. The $0.3 million decrease in accrued expenses, deferred revenue, other liabilities, and other of $0.3 million was primarily due to the increase of deferred revenue of $3.9 million associated with GSK License Agreement and an increase of $1.8 million in accrued expenses primarily due to the $1.9 million increase for product recall, offset in part by a decrease of other liabilities of $5.8 million due to the Amplity deferred fees paid in February 2023.

Net cash used in operating activities of $79.9 million for the year ended December 31, 2022, primarily consisted of the $62.8 million net loss adjusted for non-cash charges that included the gain on change in fair value of the warrant liabilities of $22.3 million and stock-based compensation expense of $3.7 million, the gain on change in fair value of the derivative liabilities of $1.3 million, and the amortization of debt issuance costs and discount of $1.6 million, plus a net favorable change in operating assets and liabilities of $0.8 million. The net favorable change in operating assets and liabilities consisted primarily of an increase in accrued expenses, other liabilities and other of $2.3 million due to the increase of $2.4 million in other liabilities associated with the long term deferred fees due to Amplity, a decrease in prepaid expenses, other assets deferred costs and other of $1.6 million primarily due to a $1.1 million decrease in prepaid inventory, offset in part due to a decrease in accounts payable of $1.5 million and an increase in accounts receivable of $1.2 million.

Net cash used in investing activities of $34.9 million for the year ended December 31, 2023, consisted of purchases of $85.5 million and maturities of $50.6 million in investments.

Net cash used in investing activities of $27.4 million for the year ended December 31, 2022, consisted of purchases of short-term investments.

Net cash used in financing activities of $36.7 million for the year ended December 31, 2023, consisted primarily of the full repayment of the Loan Agreement with Hercules and SVBB in May 2023.

Net cash provided by financing activities of $48.6 million for the year ended December 31, 2022, consisted primarily of the gross proceeds of $45.0 million from the April 2022 public offering, the $2.2 million in gross proceeds from common stock issued under our ATM and common stock purchase agreement, and the $5.0 million received from the Loan Agreement, offset in part by payments of offering costs and underwriting discounts and commissions of $3.6 million.

We expect to incur expenses in connection with our efforts to further development activities, particularly as we continue the research, development and clinical trials of, and seek regulatory approval for, product candidates. We anticipate that we will need substantial additional funding in connection with our continuing future operations.

We are continually evaluating our operating plan and assessing the optimal cash utilization for our ibrexafungerp development strategy. We have based our estimates on assumptions that may prove to be wrong, and we may use our available capital resources sooner than we currently expect. Because of the numerous risks and uncertainties associated with the development and commercialization of product candidates, we are unable to estimate the amounts of increased capital outlays and operating expenses necessary to complete the development of product candidates.

Until such time, if ever, as we can generate substantial revenue from product sales, we expect to finance our cash needs through a combination of net proceeds from equity offerings, debt financings, or other non-dilutive third-party funding (e.g., grants), strategic alliances and licensing arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interests of our common stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our common stockholders. Debt financing, similar to our Loan Agreement or the convertible senior notes we sold in March 2019 and April 2020, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If we raise additional funds through sales of assets, other third-party funding, strategic alliances and licensing or collaboration arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or to grant licenses on terms that may not be favorable to us.

Our management’s discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which we have prepared in accordance with accounting principles generally accepted in the United States, or GAAP. The preparation of our consolidated financial statements requires us to make judgments, estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of our consolidated financial statements, as well as the reported revenues and expenses during the reported periods. We evaluate these estimates and judgments on an ongoing basis. We base our assumptions and estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

While our significant accounting policies are more fully described in Note 2 to our consolidated financial statements for the year ended December 31, 2023, included in this Annual Report, we believe that the following accounting policies are critical to the process of making significant judgments and estimates in the preparation of our consolidated financial statements and understanding and evaluating our reported financial results.

We account for revenue in accordance with Accounting Standards Codification (ASC) Topic 606, Revenue from Contracts with Customers (Topic 606). Under ASC Topic 606, an entity recognizes revenue when its customer obtains control of goods and services, in an amount that reflects the consideration that the entity expects to be entitled in exchange for those goods and services. We perform the following five steps to recognize revenue under ASC Topic 606: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. We only recognize revenue when it is probable that we will collect the consideration to which we are entitled in exchange for the goods or services that will be transferred to the customer. The transaction price for product sales is reduced by variable consideration related to certain gross to net (GTN) adjustments, including chargebacks, rebates, discounts, incentives, and returns, and we will estimate the amount of this variable consideration that should be included in the transaction price using the expected value method.

Information from external sources is used to estimate GTN adjustments. Our estimate of inventory at the wholesalers is based on the projected prescription demand-based sales for our products, as well as our analysis of third-party information, including written and oral information obtained from certain wholesalers with respect to their inventory levels and sell-through to customers and third-party market research data, and our internal information. The inventory information received from wholesalers is a product of their recordkeeping process and excludes inventory held by intermediaries to whom they sell, such as retailers.

We also use information from external sources to identify prescription trends, patient demand and average selling prices. Our estimates are subject to inherent limitations of estimates that rely on third-party information, as certain third-party information was itself in the form of estimates, and reflect other limitations including lags between the date as of which third-party information is generated and the date on which we receive third-party information. Our significant GTN adjustments are further described below:

We have entered into arrangements involving the sale or license of intellectual property and the provision of other services. When entering into any arrangement involving the sale or license of intellectual property rights and other services, we determine whether the arrangement is subject to accounting guidance in ASC 606, Revenue from Contracts with Customers, as well as ASC 808, Collaborative Arrangements (Topic 808). If we determine that an arrangement includes goods or services that are central to our business operations for consideration, we will then identify the performance obligations in the contract using the unit-of-account guidance in Topic 606. For a distinct unit-of-account that is within the scope of Topic 606, we will apply all of the accounting requirements in Topic 606 to that unit-of-account, including the recognition, measurement, presentation and disclosure requirements. For a distinct unit-of-account that is not within the scope of Topic 606, we will recognize and

measure the distinct unit-of-account based on other authoritative ASC Topics or on a reasonable, rational, and consistently applied policy election.

Analyzing the arrangement to identify performance obligations requires the use of judgment. In arrangements that include the sale or license of intellectual property and other promised services, we first identify if the licenses are distinct from the other promises in the arrangement. If the license is not distinct, the license is combined with other services into a single performance obligation. Factors that are considered in evaluating whether a license is distinct from other promised services include, for example, whether the counterparty can benefit from the license without the promised service on its own or with other readily available resources and whether the promised service is expected to significantly modify or customize the intellectual property.

We assessed the terms of the GSK License Agreement and identified the following performance obligations which include: (1) the license for the development, manufacture, and commercialization of ibrexafungerp, including the approved product BREXAFEMME, in the GSK Territory, (2) the research and development activities for the MARIO study, and (3) performance obligations for the remaining research and development activities for the ongoing clinical and preclinical studies of ibrexafungerp.

For the GSK License Agreement, we allocate the transaction price based on relative standalone selling prices of each of the performance obligations. We developed the estimated standalone selling price for the license using a Monte Carlo valuation analysis and for the research and development activities, we utilized the estimate of costs to be incurred to fulfill its obligations associated with the performance of the research and development activities, plus a reasonable margin. In developing this estimate for the license, we applied significant judgment in the determination of the significant assumptions relating to forecasted future cash flows and discount rates.

We establish reserves for product recalls on a product-specific basis when circumstances giving rise to the recall become known. We estimate product returns from consumers and customers across distribution channels, utilizing third-party data and other assumptions, and these are recorded within gross-to-net expenses on our consolidated statement of operations. Additionally, we estimate costs for any additional fees, including but not limited to freight and destruction charges for returned products and costs incurred by third party vendors. These expenses are recorded within selling, general, and administrative expenses within our consolidated statement of operations as they are in excess of the initial revenue recognized. These estimates are updated and reevaluated each period and the related reserves are adjusted when these factors indicate that the recall reserves are either insufficient to cover or exceed the estimated product recall expenses. Significant changes in the assumptions used to develop estimates for product recall reserves could affect key financial information, including inventory, accrued liabilities, net sales, gross profit, and net income (loss).

We are required to estimate our expenses resulting from our obligations under contracts with CROs, clinical site agreements, vendors, and consultants in connection with conducting ibrexafungerp clinical trials and preclinical studies and other development activities. The financial terms of these contracts are subject to negotiations which vary from contract to contract and may result in payment flows that do not match the periods over which materials or services are provided to us under such contracts. Our objective is to reflect the appropriate development and trial expenses in our consolidated financial statements by matching those expenses with the period in which the services and efforts are expended by our service providers.

For clinical trials, we account for these expenses according to the progress of the trial as measured by actual hours expended by CRO personnel, investigator performance or completion of specific tasks, patient progression, or timing of various aspects of the trial. For preclinical development services performed by outside service providers, we determine accrual estimates through financial models, taking into account development progress data received from outside service providers and discussions with our knowledgeable internal personnel and service provider personnel. During the course of a clinical trial or preclinical study or development project, we adjust our rate of trial or project expense recognition if actual results differ from our estimates. We make estimates of our accrued expenses as of each balance sheet date within our consolidated financial statements based on the facts and circumstances known to us at that time. Our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and may result in our reporting changes in estimates in any particular period. We have not experienced any significant adjustments to our estimates to date.

We record the fair value of stock options issued as of the grant date as compensation expense. We recognize compensation expense over the requisite service period, which is equal to the vesting period.

Stock-based compensation expense has been reported in our statements of operations as follows (dollars in thousands):

On December 31, 2023, the aggregate intrinsic value of outstanding options to purchase shares of our common stock was $0.2 million, based upon the $2.23 closing sales price per share of our common stock as reported on the Nasdaq Global Market on that date.

We calculate the fair value of stock-based compensation arrangements using the Black-Scholes option-pricing model. The Black-Scholes option-pricing model requires the use of subjective assumptions, including volatility of our common stock, the expected term of our stock options, the risk free interest rate for a period that approximates the expected term of our stock options, and the fair value of the underlying common stock on the date of grant. In applying these assumptions, we considered the following factors:

The assumptions used in the Black-Scholes option-pricing model for the years ended December 31, 2023 and 2022 are set forth below:

We account for the outstanding warrants associated with the March 2018, December 2020, and April 2022 public offerings as liabilities measured at fair value. The fair values of these warrants have been determined using the Black-Scholes valuation model. We determine the risk-free interest rate by reference to implied yields available from U.S. Treasury securities and utilize the remaining term of the warrant as the expected term. We estimate expected volatility using the historical volatility of our common stock given we have sufficient history to support the expected terms of the warrants and implied volatility. See Note 2 to our consolidated financial statements on this Annual Report for further details.

For the convertible note, we account for the bifurcated embedded conversion option, inclusive of the interest make-whole provision and make-whole fundamental change provision, as a long-term derivative liability in our consolidated balance sheet. The derivative liability is remeasured at each reporting period using the binomial lattice model with changes in fair value recorded in the consolidated statements of operations in other (income) expense. We used the binomial lattice valuation model to value the derivative liability at inception and on subsequent valuation dates. This model incorporates transaction details such

as stock price, contractual terms, dividend yield, risk-free rate, adjusted equity volatility, credit rating, market credit spread, and estimated yield. See Note 2 to our consolidated financial statements on this Annual Report for further details.

We have audited the accompanying consolidated balance sheets of SCYNEXIS, Inc. and subsidiaries (the "Company") as of December 31, 2023 and 2022, the related consolidated statements of operations, changes in stockholders’ equity, and cash flows, for each of the two years in the period ended December 31, 2023, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2023, in conformity with accounting principles generally accepted in the United States of America.

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments.

License Agreement Revenue — Refer to Notes 1, 2 and 11 to the financial statements

On March 30, 2023, the Company entered into a license agreement (the “GSK License Agreement”) with GlaxoSmithKline Intellectual Property (No. 3) Limited ("GSK"). Pursuant to the terms of the GSK License Agreement, the Company granted GSK an exclusive, royalty-bearing, sublicensable license for the development, manufacture, and commercialization of ibrexafungerp, including the approved product BREXAFEMME, for all indications, in all countries other than Greater China and certain other countries already licensed to third parties. The Company is also responsible for the execution and costs of the ongoing clinical studies of ibrexafungerp. For the year ended December 31, 2023, the Company recognized $139.1 million of license agreement revenue related to the GSK License Agreement.

The Company is accounting for the GSK License Agreement in accordance with ASC 606, Revenue from Contracts with Customers, or ASC 606. In their accounting analysis, the Company identified distinct performance obligations, and therefore was required to estimate the transaction price upon the closing of the arrangement and allocate such amount to the respective distinct performance obligations based on their respective estimated standalone selling prices. Amounts allocated to the licenses were recognized at a point in time upon the transfer of such licenses and amounts allocated to the research and development activities were recognized over time using an input method as such services are performed.

We identified the initial accounting for the GSK License Agreement, as a critical audit matter, given the complexity involved with the identification of performance obligations and in the evaluation of whether the identified performance obligations were distinct. Auditing these conclusions involved especially subjective judgment and audit effort.

Our audit procedures related to the accounting for license revenue recorded for the GSK License Agreement included the following, among others:

Summary of Significant Accounting Policies

Concentration of Credit Risk

Financial instruments, which potentially expose the Company to concentrations of credit risk, consist principally of cash on deposit, cash equivalents, investments, and accounts receivable. The Company's money market accounts (recognized as cash and cash equivalents) and investments are with what the Company believes to be high quality issuers. The Company has not experienced any significant losses in such accounts. See Note 11 for concentrations of credit risk associated with the Company’s accounts receivable and revenue with customers.

Cash and Cash Equivalents

The Company considers any highly liquid investments with a remaining maturity of three months or less when purchased to be cash and cash equivalents. The Company reported cash, cash equivalents, and restricted cash of $34.6 million and $46.0 million as of December 31, 2023 and 2022, respectively. See Note 9 for further details on the nature of the restricted cash.

Investments

The Company's held-to-maturity investments in corporate and agency bonds are carried at amortized cost and any premiums or discounts are amortized or accreted through the maturity date of the investment. Any impairment that is not deemed to be temporary is recognized in the period identified.

Accounts Receivable, Net

Accounts receivable are reported on the accompanying consolidated balance sheet at outstanding amounts due from customers for product sales net of discounts, chargebacks, and wholesaler distribution fees. The Company evaluates the collectability of accounts receivable on a regular basis, by reviewing the financial condition and payment history of its customers, an overall review of collections experience on other accounts, and economic factors or events expected to affect future collections experience. An allowance for doubtful accounts is recorded when a receivable is deemed to be uncollectible. The Company did not record an allowance for doubtful accounts as of December 31, 2023 and 2022.

Allowance for Credit Losses

The Company reviews its held-to-maturity investments for credit losses on a collective basis by major security type and in line with the Company's investment policy. As of December 31, 2023, the Company's held-to-maturity investments were in corporate bonds, agency bonds, and U.S. government securities

, are highly rated, and the Company does not have a history of credit losses in these investments. The Company reviews the credit quality of its accounts receivables by monitoring the aging of its accounts receivable, the history of write offs for uncollectible accounts, and the credit quality of its significant customers, the current economic environment/macroeconomic trends, supportable forecasts, and other relevant factors. The Company's accounts receivable are with customers that do not have a history of uncollectability nor a history of significantly aged accounts receivables. As of December 31, 2023, the Company did not recognize a credit loss allowance for its investments or accounts receivable.

Inventory, Net

Inventory is stated at the lower of cost or net realizable value. Inventory on the accompanying balance sheet includes costs related to the raw material, third party manufacturing, and packaging for BREXAFEMME. Raw material inventory includes the costs associated with the manufacture of ibrexafungerp, the active product ingredient in BREXAFEMME. Work in process inventory includes the costs necessary to package ibrexafungerp into BREXAFEMME, at which point the inventory is then released for commercial use and considered a finished good that is available to be sold. Inventory that is not expected to be sold within one year of the reporting period is classified as long term in other assets on the consolidated balance sheet. Prior to the regulatory approval of an investigational drug, the Company recognizes as research and development expense costs related to the manufacture of an investigational drug when incurred. Upon regulatory approval, the Company begins capitalizing such production and manufacturing expenses as inventory. For BREXAFEMME, capitalization of costs as inventory began upon regulatory approval on June 1, 2021. Inventory that is deemed to not be recoverable or is obsolete is written off as an impairment expense to its net realizable value in cost of product revenues in the accompanying consolidated statement of operations.

Revenue Recognition

The Company accounts for revenue in accordance with Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (“Topic 606”). Under ASC Topic 606, an entity recognizes revenue when its customer obtains control of goods and services, in an amount that reflects the consideration that the entity expects to be entitled in exchange for those goods and services. The Company performs the following five steps to recognize revenue under ASC Topic 606: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. The Company only recognizes revenue when it is probable that it will collect the consideration to which it is entitled in exchange for the goods or services that will be transferred to the customer.

Product Revenue, Net

The Company sells BREXAFEMME primarily to wholesalers in the United States and are initially invoiced at contractual list prices. These wholesalers subsequently resell BREXAFEMME to specialty and other retail pharmacies. In addition to agreements with the wholesalers, the Company enters into arrangements with third-party payors that provide for government-mandated and/or privately-negotiated rebates, chargebacks, and discounts for the purchase of BREXAFEMME. The transaction price for product sales is reduced by variable consideration related to certain gross to net (“GTN”) adjustments, including chargebacks, rebates, discounts, incentives, and returns, and the Company will estimate the amount of this variable consideration that should be included in the transaction price using the expected value method.

Specific considerations around the Company’s product revenue gross to net GTN adjustments are as follows:

•

Voluntary Patient Assistance Programs – Through vendors, the Company offers copay assistance to provide financial assistance to patients for the portion of their prescription cost that is not covered by payors. The reduction in product revenue due to the copay programs is based on an estimate of claims and costs per claim that the Company expects to receive associated with product revenue that has been recognized. This includes potential product revenue that remains in the distribution channel at the end of a reporting period.

•

Trade Discounts and Wholesaler Fees – The Company offers discounts and pays certain distributor service fees. These are recorded as a reduction in product revenue based on distributors’ purchases and the applicable discount rate.

•

Product Stocking Fees – During the initial launch of BREXAFEMME, the Company offered additional fees to wholesalers and certain indirect customers to incent stocking at wholesalers and pharmacies. These were recorded as a reduction in product revenue based on these customer’s purchases during the eligible period and limited to a certain volume.

•

Product Returns – Generally, the Company's customers have the right to return products during the 18-month period beginning six months prior to the labeled expiration date and ending twelve months after the labeled expiration date. Since the Company has a limited history of BREXAFEMME returns, the Company estimated returns based on specific lot expiration dates and industry data for comparable products in the market. BREXAFEMME has a thirty-month shelf life.

•

Chargebacks – For certain entities, pricing on BREXAFEMME is extended below wholesaler list price. Entities that purchase BREXAFEMME from wholesalers at the lower program price then remit the Company the difference between

their acquisition cost and the lower program price, resulting in a reduction of product revenue. Accounts receivable is reduced for the estimated amount of unprocessed chargeback claims attributable to sale.

•

Commercial Rebates – The Company contracts with commercial payors such as insurers and PBMs and offer rebates for utilization and formulary status. These reserves are recorded in the same period in which the related revenue is recognized, resulting in a reduction of product revenue.

•

Government Rebates – The Company is subject to discount obligations under state Medicaid programs, Medicare, and other government programs. Provisions for government rebates are based on the estimated amount of rebates and incentives to be claimed on the related sales from the period. These reserves are recorded in the same period in which the related revenue is recognized, resulting in a reduction of product revenue. For Medicare, the Company must also estimate the number of patients in the prescription drug coverage gap for whom we will owe an additional liability under the Medicare Part D program.

The Company determined that performance obligations are satisfied and product revenue is recognized when a customer takes control of the Company’s product, which occurs at a point in time. This occurs upon delivery of the BREXAFEMME to customers, at which point the Company recognizes revenue. Payment is typically received 70 to 90 days after satisfaction of the Company’s performance obligations.

Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products to a customer (“transaction price”). The transaction price for product sales is reduced by variable consideration related to chargebacks, rebates, discounts, incentives, and returns. The Company will estimate the amount of variable consideration that should be included in the transaction price using the expected value method. These estimates take into consideration prescription demand from commercial providers, current contractual and statutory requirements, specific known market events and trends, industry data and forecasted customer buying and payment patterns, and historical trends. These provisions reflect the Company’s best estimates of the amount of consideration to which it is entitled based on the terms of the contract. The amount of variable consideration that is included in the transaction price may be constrained and is included in net sales only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized will not occur in a future period. Actual amounts of consideration ultimately received may differ from the Company’s estimates. If actual results in the future vary from the Company’s estimates, the Company will adjust these estimates, which would affect net product revenue and earnings in the period such variances become known. Sales commissions and other incremental costs of obtaining customer contracts are expensed as incurred as the amortization periods would be less than one year.

License Agreement Revenue

The Company has entered into arrangements involving the sale or license of intellectual property and the provision of other services. When entering into any arrangement involving the sale or license of intellectual property rights and other services, the Company determines whether the arrangement is subject to accounting guidance in ASC 606, Revenue from Contracts with Customers, as well as ASC 808, Collaborative Arrangements ("Topic 808"). If the Company determines that an arrangement includes goods or services that are central to the Company’s business operations for consideration, the Company will then identify the performance obligations in the contract using the unit of account guidance in Topic 606. For a distinct unit of account that is within the scope of Topic 606, the Company applies all of the accounting requirements in Topic 606 to that unit of account, including the recognition, measurement, presentation and disclosure requirements. For a distinct unit of account that is not within the scope of Topic 606, the Company will recognize and measure the distinct unit of account based on other authoritative ASC Topics or on a reasonable, rational, and consistently applied policy election.

Analyzing the license arrangements to identify performance obligations requires the use of judgment. In arrangements that include the sale or license of intellectual property and other promised services, the Company first identifies if the licenses are distinct from the other promises in the arrangement. For the license of intellectual property that is distinct, the Company recognizes revenue from consideration allocated to the license when the license is transferred and the customer is able to benefit from the license. If the license is not distinct, the license is combined with other services into a single performance obligation. Factors that are considered in evaluating whether a license is distinct from other promised services include, for example, whether the counterparty can benefit from the license without the promised service on its own or with other readily available resources and whether the promised service is expected to significantly modify or customize the intellectual property.

At the inception of each arrangement that includes milestone payments, the Company evaluates whether the milestones are considered probable of being reached. If it is probable that a significant revenue reversal would not occur, the associated milestone value is included in the transaction price. At the end of each reporting period, the Company re-evaluates the probability of achievement of milestones and any related constraint, and, if necessary, adjusts its estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which will affect revenue in the period of adjustment.

In an arrangement with multiple performance obligations, the Company develops estimates and assumptions that require judgment to determine the underlying standalone selling price for each performance obligation, which determines how the transaction price is allocated among the performance obligations. The estimation of the standalone selling price(s) include estimates regarding forecasted cash flows, discount rates, and estimates of costs to be incurred to fulfill its obligations associated with the performance of the research and development activities. The Company evaluates each performance obligation to determine if it can be satisfied at a point in time or over time. Any change made to estimated progress towards completion of a performance obligation and, therefore, license agreement revenue recognized will be recorded as a change in estimate. In addition, variable consideration must be evaluated to determine if it is constrained and, therefore, excluded from the transaction price. The Company constrains variable consideration to the extent that it is probable that it will not result in a significant revenue reversal when the uncertainty associated with the variable consideration is subsequently resolved. The Company will recognize consideration related to sales-based milestone and royalties when the subsequent sales occur pursuant to the royalty exception under ASC 606 because the license is the predominant item to which the royalties or sales-based milestone relate.

Product Recall

The Company establishes reserves for product recalls on a product-specific basis when circumstances giving rise to the recall become known. The Company estimates product returns from consumers and customers across distribution channels, utilizing third-party data and other assumptions, and these are recorded as a reduction to revenue on the Company’s consolidated statement of operations. Additionally, the Company estimates costs for any additional fees, including but not limited to freight and destruction charges for returned products and costs incurred by third party vendors. These expenses are recorded within selling, general, and administrative expenses within the Company’s consolidated statement of operations as they are in excess of the initial revenue recognized. These estimates are updated and reevaluated each period and the related reserves are adjusted when these factors indicate that the recall reserves are either insufficient to cover or exceed the estimated product recall expenses. Significant changes in the assumptions used to develop estimates for product recall reserves could affect key financial information, including inventory, accrued liabilities, net sales, gross profit, and net income (loss). As of December 31, 2023, the Company recorded products recall reserves of $1.9 million, specifically for the voluntary recall of certain lots of BREXAFEMME. The Company reviews the product recall reserve for adequacy and adjusts the product recall accrual, if necessary, based on actual experience and estimated costs to be incurred.

Cost of Product Revenues

The cost of product revenues consists primarily of impairment expense, distribution, freight costs, royalty costs, and other manufacturing costs.

Warrant Liabilities

The Company accounts for the warrants associated with the March 2018 public offering, December 2020 public offering, and April 2022 public offering as liabilities measured at fair value. The fair values of these warrants have been determined using the Black-Scholes valuation model ("Black-Scholes"). The warrants are subject to remeasurement at each balance sheet date, using Black-Scholes, with any changes in the fair value of the outstanding warrants recognized in the accompanying consolidated statements of operations.

Loan Payable

The Company initially reviews loan payables to identify the units of account for recognition purposes. The Company identifies the units of account by identifying each freestanding financial instrument included in the debt arrangement. For freestanding equity-linked financial instruments that are not in the form of shares, liability classification is used if the instrument embodies an obligation to repurchase the Company’s shares that may require the use of cash or other assets or the instrument may require the issuance of a variable number of the Company’s shares with a monetary value that is predominately based on a fixed value, based on variations in variables other than the fair value of the Company’s stock, or based on variations inversely related to the fair value of the Company’s stock. The Company will then review for embedded features within the debt instrument to evaluate whether the embedded features require bifurcation from the debt host instrument. Embedded features typically include conversion or exchange features, redemption features, or other embedded features. The identified embedded feature is bifurcated from the debt host instrument if the criteria in ASC 815-15-25-1 are met. Debt arrangements are classified on the consolidated balance sheet as current if the obligation of the debt arrangement is reasonably expected to be liquidated within twelve months. As of December 31, 2022, the Company's loan payable is recorded net of debt discount which comprised issuance costs, customary closing and final fees, and the fair value of the additional warrants issued in conjunction with the loan payable. The Company's loan payable was fully repaid in May 2023. See Note 8 for further details.

Convertible Debt and Derivative Liability

In connection with the Company’s issuance of its March 2019 6.0% Convertible Senior Notes (the “March 2019 Notes”), the Company bifurcated the embedded conversion option, inclusive of the interest make-whole provision and make-whole

fundamental change provision, and recorded the embedded conversion option as a long-term derivative liability in the Company’s balance sheet in accordance with FASB ASC 815, Derivatives and Hedging. The convertible debt and the derivative liability associated with the March 2019 Notes is presented in total on the consolidated balance sheet as the convertible debt and derivative liability. The convertible debt is carried at amortized cost. The derivative liability will be remeasured at each reporting period using the binomial lattice model with changes in fair value recorded in the consolidated statements of operations in other expense (income). See Note 8 and 14 for further details.

Research and Development

Major components of research and development costs include clinical trial activities and services, including related drug formulation, manufacturing, and other development, preclinical studies, cash compensation, stock-based compensation, fees paid to consultants and other entities that conduct certain research and development activities on the Company’s behalf, materials and supplies, legal services, and regulatory compliance.

The Company is required to estimate its expenses resulting from its obligations under contracts with clinical research organizations, clinical site agreements, vendors, and consultants in connection with conducting ibrexafungerp clinical trials and preclinical development. The financial terms of these contracts are subject to negotiations which vary from contract to contract, and may result in payment flows that do not match the periods over which materials or services are provided to the Company under such contracts. The Company’s objective is to reflect the appropriate development and trial expenses in its consolidated financial statements by matching those expenses with the period in which the services and efforts are expended. For clinical trials, the Company accounts for these expenses according to the progress of the trial as measured by actual hours expended by CRO personnel, investigator performance or completion of specific tasks, patient progression, or timing of various aspects of the trial. For preclinical development services performed by outside service providers, the Company determines accrual estimates through financial models, taking into account development progress data received from outside service providers and discussions with applicable Company and service provider personnel.

Patent Expenses

Costs related to filing and pursuing patent applications, as well as costs related to maintaining the Company's existing patent portfolio, are recorded as expense as incurred since recoverability of such expenditures is uncertain.

Fair Value of Financial Instruments

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, based on the Company’s principal or, in absence of a principal, most advantageous market for the specific asset or liability.

The Company uses a three-tier fair value hierarchy to classify and disclose all assets and liabilities measured at fair value on a recurring basis, as well as assets and liabilities measured at fair value on a non-recurring basis, in periods subsequent to their initial measurement. The hierarchy requires the Company to use observable inputs when available, and to minimize the use of unobservable inputs when determining fair value. The three tiers are defined as follows:

•

Level 1 — Observable inputs that reflect quoted market prices (unadjusted) for identical assets or liabilities in active markets;

•

Level 2 — Observable inputs other than quoted prices in active markets that are observable either directly or indirectly in the marketplace for identical or similar assets and liabilities; and

•

Level 3 — Unobservable inputs that are supported by little or no market data, which require the Company to develop its own assumptions about the assumptions market participants would use in pricing the asset or liability based on the best information available in the circumstances.

Amortization of Debt Issuance Costs and Discount

The Company’s convertible debt is recorded net of debt issuance costs and discount which comprised issuance costs and an advisory fee, and the discount initially recognized for the fair value of the bifurcated derivative liability. The portion of the debt issuance costs allocated to the convertible debt, based on the amount of proceeds allocated between the convertible debt and the derivative liability, is being amortized over the term of the convertible debt using the effective interest method in addition to the discount initially recognized for the fair value of the bifurcated derivative liability from the convertible debt. The Company’s loan payable was recorded net of debt discount which comprised issuance costs, customary closing and final fees, and the fair value of the warrants issued in conjunction with the loan payable. The resulting debt discount is being amortized over the term of the loan payable using the effective interest method. The amortization of debt issuance costs and discount is included in other expense within the accompanying consolidated statements of operations.

Income Taxes

The Company provides for deferred income taxes under the asset and liability method, whereby deferred income taxes result from temporary differences between the tax bases of assets and liabilities and their reported amounts in the consolidated financial statements. Valuation allowances are established when necessary to reduce deferred tax assets to the amount that the Company believes is more likely than not to be realized. The Company recognizes uncertain tax positions when the positions will be more likely than not sustained based solely upon the technical merits of the positions.

Stock-Based Compensation

The Company measures and recognizes compensation expense for all stock-based payment awards made to employees, officers, directors, and non-employees based on the estimated fair values of the awards as of grant date. The Company values equity instruments and stock options granted to employees and non-employees using the Black-Scholes valuation model. The value of the portion of the award that is ultimately expected to vest is recorded as expense over the requisite service periods. The Company recognize forfeitures as they are incurred.

Basic and Diluted Net Income (Loss) per Share of Common Stock

The Company calculates net income (loss) per common share in accordance with ASC 260, Earnings Per Share. Basic net income (loss) per common share for the years ended December 31, 2023 and 2022 was determined by dividing net income (loss) applicable to common stockholders by the weighted average number of common shares outstanding during the period. Per ASC 260, Earnings Per Share, the weighted average number of common shares outstanding utilized for determining the basic net income (loss) per common share for the year ended December 31, 2023 includes the outstanding pre-funded warrants to purchase 7,516,267 and 3,200,000 shares of common stock issued in the April 2022 Public Offering and December 2020 public offering, respectively. The outstanding pre-funded warrants to purchase 11,666,667 and 3,200,000 shares of common stock issued in the April 2022 Public Offering and December 2020 public offering were included in year ended December 31, 2022, respectively. Diluted net income (loss) per common share for the years ended December 31, 2023 and 2022 was determined as follows (in thousands, except share and per share amounts):


	Years Ended December 31,
	2023		2022
Net income (loss) allocated to common shares	$	67,041	$	(62,809	)

Weighted average common shares outstanding – basic		47,852,833		42,613,510
Dilutive effect of restricted stock units		537,749		—
Weighted average common shares outstanding – diluted		48,390,582		42,613,510

Net income (loss) per share – diluted	$	1.39	$	(1.47	)

The following potentially dilutive shares of common stock and outstanding restricted stock units that contain certain performance contingencies have not been included in the computation of diluted net income (loss) per share for the years ended December 31, 2023 and 2022, as the result would be anti-dilutive or the performance contingencies have not been met:


	Years Ended December 31,

Segment and Geographic Information

Operating segments are defined as components of an enterprise (business activity from which it earns revenue and incurs expenses) about which discrete financial information is available and regularly reviewed by the chief operating decision maker in deciding how to allocate resources and in assessing performance. The Company’s chief operating decision maker (“CODM”) is the Chief Executive Officer. The CODM reviews consolidated operating results to make decisions about allocating resources

and assessing performance for the entire Company. The Company views its operations and manages its business as one operating segment. The material assets of the Company were held in the United States for the years ended December 31, 2023 and 2022. In July 2019, the Company incorporated SCYNEXIS Pacific Pty Ltd, a wholly-owned subsidiary, in Sydney, Australia, for the initial purpose of conducting certain clinical trials and other research and development activities.

Although all operations are primarily based in the United States, the Company generated a portion of its revenue from the license agreements with GSK and Hansoh located outside of the United States for the years ended December 31, 2023 and 2022. All sales, including sales outside of the United States, are denominated in United States dollars.

Reclassification of Prior Year Amounts

Certain prior year amounts within the changes in operating assets and liabilities on the consolidated statement of cash flows have been reclassified for consistency with the current year presentation.

Recently Adopted Accounting Pronouncements

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). The amendments in ASU 2016-13 require a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. In November 2019, the FASB issued ASU No. 2019-10, Financial Instruments – Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842) (“ASU 2019-10”), which revised the effective dates for ASU 2016-13 for public business entities that meet the SEC definition of a smaller reporting company to fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022, with early adoption permitted. The Company adopted ASU 2016-13 on January 1, 2023 and the adoption did not materially impact the consolidated financial statements.

Recently Issued Accounting Pronouncements

In August 2020, the FASB issued ASU No. 2020-06, Debt—Debt with Conversion and Other Options and Derivatives and Hedging—Contracts in Entity’s Own Equity: Accounting for Convertible Instruments and Contracts in and Entity’s Own Equity (“ASU 2020-06”). The amendments in ASU 2020-06 reduce the number of accounting models for convertible debt instruments and revises certain guidance relating to the derivative scope exception and earnings per share. The amendments in ASU 2020-06 are effective for public business entities that meet the definition of a SEC filer and a smaller reporting company for fiscal years beginning after December 15, 2023, and interim periods within those years.

In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280), Improvements to Reportable Segment Disclosures, which introduced new guidance on disclosures for reportable segments and significant segment expenses, including for entities with a single reportable segment. This guidance is effective for the Company for annual reporting periods beginning January 1, 2024 and interim periods beginning January 1, 2025. As a smaller reporting company, the Company is currently evaluating the impact ASU 2023-07 will have on its consolidated financial statements.

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740), Improvements to Income Tax Disclosures, which introduced new guidance on disclosures for income taxes, including enhancements to the rate reconciliation and income taxes paid disclosures.

Total short-term investments	$	27,689	$	—	$	(160	)	$	27,529

The Company carries investments at amortized cost. The fair value of the corporate and agency bonds and the U.S government securities is determined based on “Level 2” inputs, which consist of quoted prices for similar assets in active markets. The Company has evaluated the unrealized loss position in the corporate and agency bonds and the U.S. government securities as of the balance sheet dates and did not consider it to be indicative of an other-than-temporary impairment as the securities are highly-rated and the Company expects to realize the full principal amount at maturity.

Borrowings

Loan Agreement

On May 13, 2021 (the “Closing Date”), the Company entered into the Loan Agreement with Hercules and SVBB for an aggregate principal amount of $60.0 million (the “Term Loan”). Pursuant to the Loan Agreement, the Term Loan was available to the Company in four tranches, subject to certain terms and conditions.

In connection with the entering into of the GSK License Agreement, the Company entered into a First Amendment and Consent to Loan and Security Agreement with the Lenders pursuant to which the Lenders consented to the Company entering into the GSK License Agreement and the Company agreed to pay to the Lenders an amount equal to the sum of (i) all outstanding principal plus all accrued and unpaid interest with respect to the amounts loaned under the Loan Agreement (approximately $35.4 million), (ii) the prepayment fee payable under the Loan Agreement ($262,500), (iii) the final payment payable under the Loan Agreement ($1,382,500), and (iv) all other sums, if any, that shall have become due and payable with respect to loan advances under the Loan Agreement. Upon receipt by the Company of the $90.0 million upfront payment from GSK in May 2023, all amounts payable under the Loan Agreement were fully paid. In connection with the repayment of those amounts due, in May 2023, the Company and the Lenders executed a payoff letter confirming the amounts due under the Loan Agreement, and the Company’s confirmation that the Loan Agreement was terminated. During the year ended December 31, 2023, the Company recognized $1.9 million in amortization for the remaining debt issuance costs and discount associated with the loan payable with Hercules and SVBB which was fully paid in May 2023.

Under the terms of the Loan Agreement, the Company received an initial tranche of $20.0 million from the Lenders on the closing date. The second tranche of the Term Loan, consisting of up to an additional $10.0 million, became available to the Company upon receipt of approval from the FDA of ibrexafungerp for the treatment of vaginal yeast infections (the “First Performance Milestone”) and was fully funded in June 2021. The third tranche of the Term Loan, consisting of an additional $5.0 million, became available to the Company upon (a) the First Performance Milestone and (b) the achievement of the primary endpoint from the Phase 3 study of ibrexafungerp in patients with recurrent vulvovaginal candidiasis, and was fully funded in March 2022. The Term Loan bore interest at a variable annual rate equal to the greater of (a) 9.05% and (b) the Prime Rate (as reported in the Wall Street Journal) plus 5.80% (the “Interest Rate”). As of December 31, 2022, the implied

secured spread, risk free rate, and secured yield were 9.84%, 4.37%, and 14.21%. At December 31, 2022, the fair value of the loan payable was $34.4 million.

March 2019 Note Purchase Agreement

On March 7, 2019, the Company entered into a Senior Convertible Note Purchase Agreement (the “March 2019 Note Purchase Agreement”) with Puissance. Pursuant to the March 2019 Note Purchase Agreement, on March 7, 2019, the Company issued and sold to Puissance $16.0 million aggregate principal amount of its March 2019 Notes, resulting in $14.7 million in net proceeds after deducting $1.3 million for an advisory fee and other issuance costs.

As of December 31, 2023 and 2022, the Company’s March 2019 Notes consists of the convertible debt balance of $12.0 million and $11.0 million and the bifurcated embedded conversion option derivative liability of $0.2 million and $42,000, respectively. In connection with the Company’s issuance of its March 2019 Notes, the Company bifurcated the embedded conversion option, inclusive of the interest make-whole provision and make-whole fundamental change provision, and recorded the embedded conversion option as a long-term derivative liability in the Company’s balance sheet in accordance with ASC 815, Derivatives and Hedging, at its initial fair value of $7.0 million as the interest make-whole provision is settled in shares of common stock. For the years ended December 31, 2023 and 2022, the Company recognized an expense of $0.2 million and a gain of $1.3 million on the fair value adjustment for the derivative liability. For the years ended December 31, 2023 and 2022, the Company recognized $1.0 million and $0.7 million, respectively, in amortization of debt issuance costs and discount, related to the March 2019 Notes.

The Company estimated the fair value of the convertible debt and derivative liability for the March 2019 Notes using a binomial lattice valuation model and Level 3 inputs. At December 31, 2023 and 2022, the fair value of the convertible debt and derivative liability for the March 2019 Notes is $12.7 million and $10.8 million, respectively.

The March 2019 Notes were issued and sold for cash at a purchase price equal to 100% of their principal amount, in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”), due to the March 2019 Notes being issued to one financially sophisticated investor. The March 2019 Notes bear interest at a rate of 6.0% per annum payable semiannually in arrears on March 15 and September 15 of each year, beginning September 15, 2019. The March 2019 Notes will mature on March 15, 2025, unless earlier converted, redeemed or repurchased. The March 2019 Notes constitute general, senior unsecured obligations of the Company.

The holder of the March 2019 Notes may convert their March 2019 Notes at their option at any time prior to the close of business on the business day immediately preceding March 15, 2025 into shares of the Company’s common stock. The initial conversion rate is 73.9096 shares of common stock per $1,000 principal amount of March 2019 Notes, which is equivalent to an initial conversion price of approximately $13.53 and is subject to adjustment in certain events described in the March 2019 Note Purchase Agreement. The Holder upon conversion may also be entitled to receive, under certain circumstances, an interest make-whole payment payable in shares of common stock. In addition, following certain corporate events that occur prior to the maturity date, the Company will, in certain circumstances, increase the conversion rate if the holder elects to convert its March 2019 Notes in connection with such a corporate event. Subject to adjustment in the conversion rate, the number of shares that the Company may deliver in connection with a conversion of the March 2019 Notes, including those delivered in connection with an interest make-whole payment, will not exceed a cap of 81 shares of common stock per $1,000 principal amount of the March 2019 Notes.

On or after March 15, 2022, the Company has the right, at its election, to redeem all or any portion of the March 2019 Notes not previously converted if the last reported sale price per share of common stock exceeds 130% of the conversion price on each of at least 20 trading days (whether or not consecutive) during the 30 consecutive trading days ending on, and including, the trading day immediately before the date the Company sends the related redemption notice. The redemption price will be 100% of the principal amount of the March 2019 Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. If a “fundamental change” (as defined in the March 2019 Note Purchase Agreement) occurs, then, subject to certain exceptions, the Company must offer to repurchase the March 2019 Notes for cash at a repurchase price of 100% of the principal amount of the March 2019 Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the repurchase date.

Other Liabilities

In February 2021, the Company partnered with Amplity for the commercial launch of BREXAFEMME for the treatment of VVC. Under the terms of the agreement with Amplity, the Company was to utilize Amplity’s commercial execution and resources for sales force, remote engagement, training, market access and select operations services. In October 2022, the Company announced that it was actively pursuing a U.S. commercialization partner to out-license BREXAFEMME in order to refocus the Company's resources on the further clinical development of ibrexafungerp for severe, hospital-based indications. As a result, the Company wound down its promotional activities associated with BREXAFEMME, while keeping BREXAFEMME on the market and available to patients. On November 30, 2022, the Company terminated the agreement with Amplity.

Under the terms of the original agreement, Amplity deferred a portion of its direct service fees in the first two years (2021 and 2022) that accrued interest at an annual rate of 12.75% (“Deferred Fees”). As of December 31, 2022, Deferred Fees of $5.8 million, which includes a portion of the $1.5 million termination fee that was unpaid as of December 31, 2022, are recognized as short term other liabilities in the consolidated balance sheets. The $5.8 million of Deferred Fees as of December 31, 2022 was fully paid as of February 2023. Additionally, as a result of the reduction in internal workforce in the Company's commercial function in 2022, the Company recognized $1.3 million in severance costs during the year ended December 31, 2022.

Commitments and Contingencies

Leases

On March 1, 2018, the Company entered into a long-term lease agreement for approximately 19,275 square feet of office space in Jersey City, New Jersey, that the Company identified as an operating lease under ASC 842 (the “Lease”). The lease term is eleven years from August 1, 2018, the commencement date, with total lease payments of $7.3 million over the lease term. The Company has the option to renew for two consecutive five-year periods from the end of the first term and the Company is not reasonably certain that the option to renew the Lease will be exercised. Under the Lease, the Company furnished a security deposit in the form of a standby letter of credit in the amount of $0.3 million, which will be reduced by fifty-five thousand dollars every two years for ten years after the commencement of the lease. The security deposit is classified as restricted cash in the accompanying consolidated balance sheets.

The consideration in the Lease allocated to the single lease component includes the fixed payments for the right to use the office space as well as common area maintenance. The Lease also contains costs associated with certain expense escalation, property taxes, insurance, parking, and utilities which are all considered variable payments and are excluded from the operating lease liability. The incremental borrowing rate utilized approximated the prevailing market interest rate the Company would incur to borrow a similar amount equal to the total Lease payments on a collateralized basis over the term of the Lease. The following table summarizes certain quantitative information associated with the amounts recognized in the accompanying consolidated financial statements for the Lease (dollars in thousands):

License Arrangements with Potential Future Expenditures

As of December 31, 2023, the Company had a license arrangement with Merck Sharp & Dohme Corp., or Merck, as amended, that involves potential future expenditures. Under the license arrangement, executed in May 2013, the Company exclusively licensed from Merck its rights to ibrexafungerp in the field of human health. In January 2014, Merck assigned the patents related to ibrexafungerp that it had exclusively licensed to the Company. Ibrexafungerp is the Company's lead product candidate. Pursuant to the terms of the license agreement, Merck was originally eligible to receive milestone payments from the Company that could total $19.0 million upon occurrence of specific events, including initiation of a Phase 2 clinical study, new drug application, and marketing approvals in each of the U.S., major European markets, and Japan. In addition, Merck is eligible to receive tiered royalties from the Company based on a percentage of worldwide net sales of ibrexafungerp. The aggregate royalties are mid- to high-single digits.

In December 2014, the Company and Merck entered into an amendment to the license agreement that deferred the remittance of a milestone payment due to Merck, such that no amount would be due upon initiation of the first Phase 2 clinical trial of a product containing the ibrexafungerp compound (the “Deferred Milestone”). The amendment also increased, in an amount equal to the Deferred Milestone, the milestone payment that would be due upon initiation of the first Phase 3 clinical trial of a product containing the ibrexafungerp compound. In December 2016 and January 2018, the Company entered into second and third amendments to the license agreement with Merck which clarified what would constitute the initiation of a Phase 3 clinical trial for the purpose of milestone payment. In January 2019, a milestone payment became due to Merck as a result of the initiation of the VANISH Phase 3 VVC program and was paid in March 2019. On December 2, 2020, the Company entered into a fourth amendment to the license agreement with Merck. The amendment eliminates two cash milestone payments that the Company would have paid to Merck upon the first filing of a NDA, triggered by the FDA acceptance for filing of its NDA for ibrexafungerp for the treatment of VVC, and first marketing approval in the U.S., in June 2021 for the Company’s NDA for ibrexafungerp for the treatment of VVC. Such cash milestone payments would have been creditable against future royalties owed to Merck on net sales of ibrexafungerp. With the amendment, these milestones will not be paid in cash and, accordingly, credits will not accrue. Pursuant to the amendment, the Company will also forfeit the credits against future royalties that it had accrued from a prior milestone payment already paid to Merck. All other key terms of the license agreement are unchanged.

Clinical Development Arrangements

The Company has entered into, and expects to continue to enter into, contracts in the normal course of business with various third parties who support its clinical trials, preclinical research studies, and other services related to its development activities. The scope of the services under these agreements can generally be modified at any time, and the agreement can be terminated by either party after a period of notice and receipt of written notice.

Preferred Stock

On May 7, 2014, the Company amended and restated its articles of incorporation relating to its approved capital structure. The Company’s board of directors has authorized the Company, subject to limitations prescribed by Delaware law, to issue up to 5,000,000 shares of preferred stock with a par value of $0.001 per share in one or more series, to establish from time to time the number of shares to be included in each series and to fix the designation, powers, preferences and rights of the shares of each series and any of its qualifications, limitations or restrictions. The Company’s board of directors can also increase or decrease the number of shares of any series of preferred stock, but not below the number of shares of that series then outstanding, without any further vote or action by the stockholders. The Company’s board of directors may authorize the issuance of preferred stock with voting or conversion rights that could adversely affect the voting power or other rights of the holders of the common stock. There were no shares of preferred stock issued and outstanding as of December 31, 2023 and 2022.

Common Stock Purchase Agreement and Sales Agreements

On April 10, 2020, the Company entered into the Common Stock Purchase Agreement with Aspire Capital (the “Common Stock Purchase Agreement”) pursuant to which the Company had the right to sell to Aspire Capital from time to time in its sole discretion up to $20.0 million in shares of the Company’s common stock, subject to certain limitations and conditions set forth in the Common Stock Purchase Agreement. The Common Stock Purchase Agreement expired in October 2022. During the year ended December 31, 2022, the Company sold 425,000 shares of its common stock under the Common Stock Purchase Agreement for gross proceeds of $1.6 million.

During the years ended December 31, 2023, and 2022, the Company sold zero and 137,610 shares of its common stock and received net proceeds of zero and $0.7 million, respectively, under the Controlled Equity OfferingSM Sales Agreements with Cantor Fitzgerald & Co. and Ladenburg Thalmann & Co. Inc. (the “Sales Agreements”).

April 2022 Public Offering

On April 22, 2022, the Company entered into an Equity Underwriting Agreement (the “Underwriting Agreement”) with Guggenheim Securities, LLC, as representative of the several underwriters (the “Underwriters”), relating to the offering, issuance and sale (the “April 2022 Public Offering”) of (a) 3,333,333 shares of the Company’s common stock, par value $0.001 per share, (b) prefunded warrants, in lieu of common stock, to purchase 11,666,667 shares of the Company’s common stock, par value $0.001 per share, and (c) warrants, which will accompany the common stock or prefunded warrants, to purchase up to an aggregate of 15,000,000 shares of the Company’s common stock. The prefunded warrants entitle the holders to purchase up to 11,666,667 shares of common stock and have an unlimited term and an exercise price of $0.001 per share. The warrants entitle the holders to purchase up to an aggregate of 15,000,000 shares of common stock and have a seven-year term and an exercise price of $3.45 per share. The warrants that accompany the prefunded warrants have an additional provision entitling the holder thereof to purchase a prefunded warrant rather than a share of common stock at the warrant exercise price less the exercise price of the prefunded warrant purchased. Each warrant is exercisable immediately upon issuance, subject to certain limitations on beneficial ownership. The price to the public in the April 2022 Public Offering was $3.00 per share of common stock and accompanying warrants, or in the case of prefunded warrants, $2.999 per prefunded warrant and accompanying warrants, which resulted in $41.8 million of net proceeds to the Company after deducting the underwriting discount and offering expenses.

The prefunded warrants are classified as equity in accordance with ASC 815, Derivatives and Hedging, given the prefunded warrants are indexed to the Company’s own shares of common stock and meet the requirements to be classified in equity. The prefunded warrants were recorded at their relative fair value at issuance in the stockholders’ equity section of the balance sheet and the prefunded warrants are considered outstanding shares in the basic earnings per share calculation for the years ended December 31, 2023 and 2022 given their nominal exercise price. For the years ended December 31, 2023 and 2022, 4,150,400 and zero of the prefunded warrants from the April 2022 Public Offering were exercised for total proceeds of $4,150 and zero, respectively.

December 2020 Public Offering Warrants

On December 17, 2020, the Company completed a public offering (the “December 2020 Public Offering”) of its common stock and warrants pursuant to the Company’s effective shelf registration. The Company sold an aggregate of (a) 8,340,000 shares of the Company’s common stock, par value $0.001 per share, (b) prefunded warrants, in lieu of common stock, to purchase 5,260,000 shares of the Company’s common stock, par value $0.001 per share, and (c) two series of warrants, which will accompany the common stock or prefunded warrants, to purchase up to an aggregate of 13,600,000 shares of the Company’s common stock. The Series 1 warrants expired in December 2021 and there were 6,800,000 of the Series 2 warrants outstanding as of December 31, 2023 and 2022. The outstanding prefunded warrants as of December 31, 2023 and 2022 entitle the holders to purchase up to 3,200,000 shares of common stock and have an unlimited term and an exercise price of $0.001 per share.

The Series 2 warrants have a three-and-a-half-year term and an exercise price of $8.25 per share. There is not expected to be any trading market for the prefunded warrants or the Series 2 warrants issued in the offering. Each warrant is exercisable immediately upon issuance, subject to certain limitations on beneficial ownership. The Series 2 warrants that accompany the prefunded warrants have an additional provision, if certain beneficial ownership limitations are met, entitling the holder thereof to purchase a prefunded warrant rather than a share of common stock at the warrant exercise price less the exercise price of the prefunded warrant purchased. The price to the public in the offering was $6.25 per share of common stock and accompanying warrants, or in the case of prefunded warrants, $6.249 per prefunded warrant and accompanying warrants.

Public Offering Warrant Liabilities

The outstanding warrants associated with the March 2018 and December 2020 public offerings contain a provision where the warrant holder has the option to receive cash, equal to the Black-Scholes fair value of the remaining unexercised portion of the warrant, as cash settlement in the event that there is a fundamental transaction (contractually defined to include various merger, acquisition or stock transfer activities). Due to this provision, ASC 480, Distinguishing Liabilities from Equity, requires that these warrants be classified as liabilities. The fair values of these warrants have been determined using the Black-Scholes

valuation model, and the changes in the fair value are recorded in the accompanying consolidated statements of operations. The outstanding warrants associated with the April 2022 Public Offering meet the definition of a derivative pursuant to ASC 815, Derivatives and Hedging, and do not meet the derivative scope exception given the warrants do not qualify under the indexation guidance. As a result, the April 2022 Public Offering warrants were initially recognized as liabilities and measured at fair value using the Black-Scholes valuation model. During the year ended December 31, 2023 and 2022, the Company recognized a loss of $3.2 million and a gain $22.3 million, respectively, due to the change in fair value of the warrant liabilities. Issuance costs of $1.7 million initially allocated to the April 2022 Public Offering warrant liabilities were written off upon settlement and were recognized in the gain on the fair value adjustment for the warrant liabilities for the year ended December 31, 2022. As of December 31, 2023 and 2022, the fair value of the warrant liabilities were $21.8 million and $18.6 million, respectively.

Warrant Associated with Danforth Advisors

Pursuant to a consulting agreement with Danforth Advisors (“Danforth”) entered into in November 2021, the Company issued to Danforth a warrant to purchase 50,000 shares of the Company’s common stock at an exercise price of $5.50 per share. The warrant will expire five years from the date of the grant.

Revenue

Product Revenue, Net

Net product revenue was $1.0 million and $5.0 million for the years ended December 31, 2023 and 2022, respectively. Products are sold primarily to wholesalers and specialty pharmacies. Revenue is reduced from wholesaler list price at the time of recognition for expected chargebacks, rebates, discounts, incentives, and returns, which are referred to as gross to net (“GTN”) adjustments. These reductions are currently attributed to various commercial arrangements. Chargebacks and discounts are recognized as a reduction in accounts receivable or as accrued expenses based on their nature and settled through the issuance of credits to the customer or through cash payments to the customer, respectively. All other returns, rebates, and incentives are reflected as accrued expenses and settled through cash payments to the customer. Three wholesalers comprised 44%, 28%, and 26% of the Company’s gross revenue for the year ended December 31, 2023, and 45%, 28%, and 21% of the Company’s gross revenue for the year ended December 31, 2022.

The following table summarizes activity in each of the Company’s product revenue provision and allowance categories as of December 31, 2023 and 2022 (in thousands):

Discounts and chargebacks include fees for wholesaler fees, prompt pay and other discounts, and chargebacks. Discounts and chargebacks are deducted from gross revenue at the time revenues are recognized and are included as a reduction in accounts receivable or as an accrued expense based on their nature on the Company’s consolidated balance sheet.

(2)

Provisions for product returns are deducted from gross revenues at the time revenues are recognized and are included in accrued expenses on the Company’s consolidated balance sheet.

(3)

Rebates and incentives include rebates and co-pay program incentives. Provisions for rebates and incentives are deducted from gross revenues at the time revenues are recognized and are included in accrued expenses on the Company’s consolidated balance sheets.

(4)

Provisions for product recall are deducted from gross revenues to the extent of revenue recorded related to the recalled product and are included in accrued expenses on the Company’s consolidated balance sheet.

GSK License Agreement

On March 30, 2023, the Company entered into the GSK License Agreement. Pursuant to the terms of the GSK License Agreement, the Company granted GSK an exclusive (even as to the Company and its affiliates), royalty-bearing, sublicensable license for the development, manufacture, and commercialization of ibrexafungerp, including the approved product BREXAFEMME, for all indications, in all countries other than Greater China and certain other countries already licensed to third parties (the “GSK Territory”). If the existing licenses granted to or agreements with third parties are terminated with respect to any country, GSK will have an exclusive first right to negotiate with the Company to add those additional countries to the GSK Territory. The parties closed the transactions contemplated by the GSK License Agreement in May 2023.

The Company retains rights to all other assets, with GSK receiving a right of first negotiation (“ROFN”) to any other enfumafungin-derived compounds or products that the Company may control. Under the terms of the original GSK License Agreement, the Company received a nonrefundable upfront payment of $90 million in May 2023. The Company was initially also eligible to receive potential:

•

regulatory approval milestone payments of up to $70 million;

•

commercial milestone payments of up to $115 million based on first commercial sale in invasive candidiasis (U.S./EU); and

•

and sales milestone payments of up to $242.5 million based on annual net sales, with a total of $77.5 million to be paid upon achievement of multiple thresholds up through $200 million; a total of $65 million to be paid upon achievement of multiple thresholds between $300 million and $500 million; and $50 million to be paid at each threshold of $750 million and $1 billion.

As previously disclosed, the Company became aware that a non-antibacterial beta-lactam drug substance was manufactured using equipment common to the manufacturing process for ibrexafungerp. Current FDA draft guidance recommends segregating the manufacture of non-antibacterial beta-lactam compounds from other compounds since beta-lactam compounds have the potential to act as sensitizing agents that may trigger hypersensitivity or an allergic reaction in some people. In the absence of the recommended segregation, there is a risk of cross contamination. It is not known whether any ibrexafungerp has been contaminated with a beta-lactam compound. Nonetheless, in light of this risk and out of an abundance of caution, BREXAFEMME (ibrexafungerp tablets) was recalled from the market and clinical studies of ibrexafungerp were placed on temporary hold.

On December 26, 2023, the Company and GSK entered into a binding memorandum of understanding ("Binding MOU") for amendment to the GSK License Agreement. The GSK License Agreement was amended in connection with the delay in the commercialization of BREXAFEMME and further clinical development of ibrexafungerp associated with this event. Under the terms of the updated GSK License Agreement, as amended by Binding MOU, the Company is now eligible to receive potential:

•

regulatory approval milestone payments of up to $49 million (revised from up to $70 million as provided in the GSK License Agreement);

•

commercial milestone payments of up to $57.5 million based on first commercial sale in invasive candidiasis (U.S./EU) (revised from up to $115 million as provided in the GSK License Agreement); and

•

and sales milestone payments of up to $179.5 / $169.75 / $145.5 million (depending on the date of GSK’s relaunch of BREXAFEMME in the U.S.) (revised from up to $242.5 million as provided in the GSK License Agreement).

The Company will continue to be responsible for the execution and costs of the ongoing clinical studies of ibrexafungerp but will have the potential to receive up to $72.35 million in development milestones (revised from up to $75.5 million as provided in the GSK License Agreement), which comprise: $25 million already paid; $10 million for the delivery to GSK of final clinical study reports for the completed FURI, CARES, and NATURE clinical studies; up to $30 million for the achievement of two interim milestones associated with the Company's resumption and continued performance of the MARIO Study after the clinical hold is lifted; and $7.35 million for the successful completion of the MARIO Study.

These royalty rates are subject to reduction, including in the event of third-party licenses, entry of a generic product, or the expiration of licensed patents. A joint development committee was established between GSK and the Company to coordinate and review ongoing development activities of ibrexafungerp. Unless earlier terminated, the GSK License Agreement will expire on a product-by-product and country-by-country basis at the end of the royalty term for such product in such country. The Company has the right to terminate the GSK License Agreement upon an uncured material breach by, or bankruptcy of, GSK. GSK has the right to terminate the GSK License Agreement at any time for convenience in its entirety or on a product-by-product and country-by-country basis, upon an uncured material breach by, or bankruptcy of, the Company, or for safety reasons.

The Company evaluated the GSK License Agreement in accordance with ASC 606 as it includes a customer-vendor relationship as defined under ASC 606 and meets the criteria to be considered a contract. The Company assessed the terms of the GSK License Agreement and identified the following performance obligations which include: (1) the license for the development, manufacture, and commercialization of ibrexafungerp, including the approved product BREXAFEMME, in the GSK Territory, (2) the research and development activities for the MARIO study, and (3) performance obligations for the remaining research and development activities for the ongoing clinical and preclinical studies of ibrexafungerp. For the years ended December 31, 2023 and 2022, the Company's product revenue, net comprised of sales of BREXAFEMME that the Company sold as principal given it maintains control of BREXAFEMME product until delivery to its wholesalers at which point control is transferred.

The Company considers the future potential development, regulatory, and commercial milestone payments as well as sales-based milestone and royalties to be variable consideration. The Company constrains variable consideration to the extent that it is probable that it will not result in a significant revenue reversal when the uncertainty associated with the variable consideration is subsequently resolved. The Company will recognize consideration related to sales-based milestone and royalties when the subsequent sales occur pursuant to the royalty exception under ASC 606 because the license is the predominant item to which the royalties or sales-based milestone relate.

The total transaction price was $136.1 million as of June 30, 2023, which included the initial payment of $90.0 million and $45.0 million in success-based development milestones. Given the uncertain nature of these payments, the remaining potential development, regulatory, and commercial milestone payments from the GSK License Agreement are not included in the transaction price as they were determined to be fully constrained under ASC 606. The Company allocated the $136.1 million transaction price based on relative standalone selling prices of each of the performance obligations as $130.1 million for the license, $4.8 million for the research and development activities for the MARIO study and $1.2 million for the remaining ongoing clinical and preclinical studies of ibrexafungerp. The Company developed the estimated standalone selling price for the license using a Monte Carlo valuation analysis and for the research and development activities, the Company's utilized the estimate of costs to be incurred to fulfill its obligations associated with the performance of the research and development activities, plus a reasonable margin. In developing this estimate for the license, the Company applied significant judgment in the determination of the significant assumptions relating to forecasted future cash flows and discount rates. As of June 30, 2023, the Company provided all necessary information to GSK for it to benefit from the license under the license term. Accordingly, the Company recognized $130.1 million in license agreement revenue at a point in time upon the transfer of the license to GSK as of June 30, 2023.

For the year ended December 31, 2023, the Company recognized $139.0 million in license agreement revenue. As of December 31, 2023, the Company recognized a $19.3 million contract asset associated with the success-based milestones associated with the ongoing clinical studies of ibrexafungerp. The Company believes that the $19.3 million contract asset is collectible given the Company's probability assessment of achieving the milestones as defined in the GSK License Agreement, ongoing development activities, and other information available to the Company. The Company reassessed the transaction price as of December 31, 2023, including estimated variable consideration included in the transaction price and the remaining milestones continued to be constrained.

The Company recognized the revenue associated with the MARIO study and the remaining ongoing clinical and preclinical studies of ibrexafungerp over time using an input method. The input method is based on the actual costs incurred as a percentage of total budgeted costs towards satisfying the performance obligation as this method provides the most faithful depiction of the Company’s performance in transferring control of the services promised to GSK and represents the Company’s best estimate of the period of the obligation. For the year ended December 31, 2023, the Company recognized $1.7 million of license agreement revenue from the research and development activities associated with the MARIO study and the remaining ongoing clinical and preclinical studies of ibrexafungerp. As of December 31, 2023, there is $1.2 million and $2.7 million of current and long-term deferred revenue, respectively, which is expected to be recognized by the end of 2025.

The Binding MOU was considered to represent a contract modification pursuant to ASC 606. As a result, the Company recorded $4.4 million that was included in license agreement revenue for the year ended December 31, 2023. The $4.4 million was recognized as an unbilled receivable as of December 31, 2023 and included in prepaid expenses and other current assets in the consolidated balance sheets.

Until the product recall, the Company continued to sell BREXAFEMME in the GSK Territory. The Company was the principal for these transactions under ASC 606 as the Company maintained control of the BREXAFEMME inventory that was then sold to its customers.

Hansoh License Agreement

In February 2021, the Company entered into an Exclusive License and Collaboration Agreement (the “Hansoh License Agreement”) with Hansoh (Shanghai) Health Technology Co., Ltd., and Jiangsu Hansoh Pharmaceutical Group Company Limited (collectively, “Hansoh”), pursuant to which the Company granted to Hansoh an exclusive license to research, develop and commercialize ibrexafungerp in the Greater China region, including mainland China, Hong Kong, Macau, and Taiwan (the “Territory”). The Company also granted to Hansoh a non-exclusive license to manufacture ibrexafungerp solely for development and commercialization in the Territory. Under the terms of the Hansoh License Agreement, Hansoh shall be responsible for the development, regulatory approval and commercialization of ibrexafungerp in the Territory.

Pursuant to the terms of the Hansoh License Agreement, the Company received as consideration for the licenses a nonrefundable upfront cash payment of $10.0 million and is entitled to an additional payment that was payable upon the transfer of certain data related to the manufacturing license. In addition, the Company will also be eligible to receive up to $110.0 million in potential development and commercial milestones. In addition, during the term of the licensing agreement, the Company is entitled to low double-digit royalties on net product sales. The obligation to pay royalties with respect to sales in a specified region will continue until the later of the date of expiration of all intellectual property and regulatory exclusivity for the product in the region and ten years from the first commercial sale, unless earlier terminated by Hansoh with advanced notice for convenience or under other specified circumstances. The Company is also eligible to receive a milestone related to the successful completion of a manufacturing batch by Hansoh.

The Company evaluated the Hansoh License Agreement and concluded that it was subject to ASC 606 as the Company viewed the Hansoh License Agreement as a contract with a customer as the activities were central to its business operations. As such, the Company assessed the terms of the Hansoh License Agreement and identified one performance obligation for the licenses to research, develop, manufacture and commercialize ibrexafungerp in the Territory, including the underlying know-how related to such licenses. The Company also evaluated options for additional goods and services included in the Hansoh License Agreement related to (1) optional technical assistance related to development, regulatory or manufacturing activities and (2) a supply agreement for ibrexafungerp. Such options for additional goods or services were not considered to contain material rights as pricing approximated standalone selling prices and therefore the Company concluded that such options did not represent performance obligations and will be accounted for as separate transactions if and when they occur in the future.

The Company determined that the transaction price of $12.1 million included the fixed upfront cash payment of $10.0 million, an additional amount that was payable upon the transfer of certain data related to the manufacturing license, and $1.1 million related to withholding tax obligations that Hansoh remitted on behalf of the Company. The remaining amounts related to the successful completion of a manufacturing batch by Hansoh and potential development milestones represent variable consideration and were constrained as it was concluded that it was not probable that a significant reversal in cumulative revenue recognized will not occur and therefore not included in the transaction price as of December 31, 2023 and 2022. Potential commercial milestones and royalties on net product sales will be recognized in the same period that the underlying net product sales occur as they were determined to relate to the license. The transaction price was recorded in revenue during the year ended December 31, 2021 at a point in time upon control of the license transferring to Hansoh. The Company will reevaluate the transaction price at the end of each reporting period as uncertain events or resolved, or as other changes in circumstances occur.

Additionally, pursuant to the Hansoh License Agreement, both the Company and Hansoh agreed to make reasonable efforts to account for applicable taxes, fees, duties, levies, or similar amounts imposed on net income, franchise taxes and profits arising directly or indirectly from the activities of the Hansoh License Agreement. To the extent Hansoh is required by applicable laws to withhold or deduct any tax on any payment to the Company, Hansoh agreed to make certain increases on payments to the Company to ensure that the Company receives a sum equal to what the Company would have received had there been no deduction or withholding. As a result, the Company has recorded revenue and tax withholding expense primarily associated with the up-front payment received by the Company on a gross basis.

Cypralis and Waterstone License Agreements

In July 2016, the Company entered into an asset purchase agreement with UK-based Cypralis Limited (or "Cypralis"), a life sciences company, for the sale of its cyclophilin inhibitor assets. Cypralis also acquired all patents, patent applications and know-how related to the acquired portfolio. In connection with the asset purchase agreement, the Company is eligible to receive milestone payments upon the successful progression of Cypralis clinical candidates into later stage clinical studies and royalties payable upon product commercialization. The Company retains the right to repurchase the portfolio assets from Cypralis if abandoned or deprioritized. For the years ended December 31, 2023 and 2022, there was no revenue recognized associated with this agreement given the variable consideration associated with the sale of intellectual property to Cypralis was

fully constrained as of December 31, 2023. Additionally, in October 2014 the Company entered into a license agreement with Waterstone Pharmaceutical HK Limited (or “Waterstone”) and granted Waterstone an exclusive, worldwide license to develop and commercialize certain non-strategic compounds. The Company is entitled to receive potential milestones and royalties from Waterstone; however, there was no revenue recognized by the Company in 2023 and 2022 associated with this agreement given the variable consideration was fully constrained as of December 31, 2023 and 2022.

Income Taxes

The Company’s consolidated financial statements include a total tax expense of $0.1 million and a tax benefit of $4.7 million on income before taxes of $67.2 million and a loss before taxes of $67.5 million for the years ended December 31, 2023 and 2022, respectively.

As of December 31, 2023 and 2022, the Company had available federal net operating loss (“NOL”) carryforwards of approximately $205.7 million and $405.0 million, respectively, and state and net operating loss carryforwards of approximately $141.2 million and $116.8 million, respectively. The Company’s state and net operating loss carryforwards began to expire in 2019. As of December 31, 2023, the Company had available federal research and development credit carryforwards of $1.0 million which began to expire in 2022.

We completed a Section 382 study of transactions in our stock through December 31, 2023 and concluded that we have experienced ownership changes since inception that we believe under Section 382 and 383 of the Code will result in limitations

on our ability to use certain pre-ownership change NOLs and credits. In addition, we may experience subsequent ownership changes as a result of future equity offerings or other changes in the ownership of our stock, some of which are beyond our control. As a result, the amount of the NOLs and tax credit carryforwards presented in our consolidated financial statements are limited and the related amounts have been updated. Similar provisions of state tax law may also apply to limit the use of accumulated state tax attributes.

The New Jersey Technology Business Tax Certificate Transfer (NOL) program, administered by the New Jersey Economic Development Authority, enables approved biotechnology companies to sell their unused net operating losses (“NOLs”) and research and development tax credits to unaffiliated, profitable corporate taxpayers in the State of New Jersey (“NJ”) up to a maximum lifetime benefit of $20.0 million per business. As of December 31, 2022, the Company has received approximately $18.8 million under the program. In February 2022, the Company received a cash receipt of $4.7 million from the sale of its NJ state NOLs. The Company recognized an income tax benefit of $4.7 million for the year ended December 31, 2022 in the consolidated statement of operations.

On December 22, 2017, the “Tax Cuts and Jobs Act” was signed into law. The tax reform has the following effects on the Company: (1) permanently reduces the maximum corporate income tax rate from 35% to 21% effective for tax years beginning after December 31, 2017, (2) allows temporary 100% expensing for certain business assets and property placed in service after September 27, 2018 and before January 1, 2023, (3) disallows NOL carrybacks but allows for the indefinite carryforward of those NOLs which applies to losses arising in tax years beginning after December 31, 2018 and, (4) limits NOL deductions for each year equal to the lesser of the available carryover or 80% of a taxpayer’s pre-NOL deduction taxable income. This applies to losses arising in tax years ending on or after December 31, 2017. As of December 31, 2023 and 2022, the Company has concluded that it is more likely than not that the Company will not realize the benefit of its deferred tax assets due to its history of losses. Accordingly, the net deferred tax assets have been fully reserved.

All tax years remain open to examination by U.S. federal and state income tax authorities because the Company has incurred cumulative net operating losses since inception.

The Company applies ASC 740-10-25-5, Income Taxes, formerly FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes, as amended, on January 1, 2009. The difference between the tax benefit recognized in the financial statements and the tax benefit claimed in the tax return is referred to as an unrecognized tax benefit.

The following is a tabular reconciliation of the total amounts of unrecognized tax benefits as of December 31, 2023 and 2022 (in thousands):


	December 31,
	2023			2022
Unrecognized tax benefit—January 1	$	436		$	436
Additions for tax positions of current period		—			—
Additions for tax positions of prior periods		—			—
Deferred rate change		(75	)		—
Unrecognized tax benefit—December 31	$	361		$	436

None of the unrecognized tax benefits would, if recognized, affect the effective tax rate because the Company has recorded a valuation allowance to fully offset federal and state deferred tax assets. The Company has no tax positions for which it is reasonably possible that the total amount of unrecognized tax benefits will significantly increase or decrease within the coming year. The Company has $0 provided for interest and penalties associated with uncertain tax positions.

Stock-based Compensation

2009 Stock Option Plan

The Company had a share-based compensation plan (the “2009 Stock Option Plan”) under which the Company granted options to purchase shares of common stock to employees, directors, and consultants as either incentive stock options or nonqualified stock options. Incentive stock options could be granted with exercise prices not less than 100% to 110% of the fair market value of the common stock. Options granted under the plan generally vest over three to four years and expire in 10 years from the date of grant.

2014 Equity Incentive Plan

In February 2014, the Company’s board of directors adopted the 2014 Equity Incentive Plan (“2014 Plan”), which was subsequently ratified by its stockholders and became effective on May 2, 2014 (the “Effective Date”). The 2014 Plan, as amended on June 18, 2014, February 25, 2015, and July 2023, is the successor to and continuation of the 2009 Stock Option Plan. As of the Effective Date, no additional awards will be granted under the 2009 Stock Option Plan, but all stock awards

granted under the 2009 Stock Option Plan prior to the Effective Date will remain subject to the terms of the 2009 Stock Option Plan. All awards granted on and after the Effective Date will be subject to the terms of the 2014 Plan. The 2014 Plan provides for the grant of the following awards: (i) incentive stock options, (ii) nonstatutory stock options, (iii) stock appreciation rights, (iv) restricted stock awards, (v) restricted stock unit awards, and (vi) other stock awards. Employees, directors, and consultants are eligible to receive awards. Options granted under the plan generally vest over three to four years and expire in 10 years from the date of grant.

Under the 2014 Plan, after giving effect to the increases to the share reserve approved by the Company’s stockholders in September 2014, and June 2015, but excluding the automatic increases discussed below, the aggregate number of shares of common stock that could be issued from and after the Effective Date (the “share reserve”) could not exceed the sum of (i) 112,273 new shares, (ii) the shares that represented the 2009 Stock Option Plan’s available reserve on the Effective Date, and (iii) any returning shares from the 2009 Stock Option Plan. Under the 2014 Plan, the share reserve will automatically increase on January 1st of each year, for a period of not more than 10 years, commencing on January 1, 2015, and ending on January 1, 2024, in an amount equal to 4.0% of the total number of shares of capital stock outstanding on December 31st of the preceding calendar year. The board of directors may act prior to January 1st of a given year to provide that there will be no increase in the share reserve or that the increase will be a lesser number of shares than would otherwise occur.

Pursuant to the terms of the 2014 Plan, on January 1, 2023 and 2022, the Company automatically added 1,901,960 and 1,148,213 shares to the total number shares of common stock available for future issuance under the 2014 Plan, respectively. As of December 31, 2023, there were 848,202 shares of common stock available for future issuance under the 2014 Plan.

2015 Inducement Plan

On March 26, 2015, the Company's board of directors adopted the 2015 Inducement Plan (“2015 Plan”). The 2015 Plan provides for the grant of nonstatutory stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards, and other forms of equity compensation (collectively, stock awards), all of which may be granted to persons not previously employees or directors of the Company, or following a bona fide period of non-employment, as an inducement material to the individuals’ entering into employment with the Company within the meaning of NASDAQ Listing Rule 5635I(4). The 2015 Plan had an initial share reserve covering 45,000 shares of common stock. On June 9, 2019, April 30, 2021, and October 18, 2022, the Company’s board of directors amended the 2015 Plan, and the initial share reserve for the 2015 Plan was increased from 45,000 to 90,000, from 90,000 to 500,000, and from 500,000 to 900,000 shares of common stock, respectively. During the years ended December 31, 2023 and 2022, there were zero and 279,000 granted options of the Company’s common stock under the 2015 Plan, respectively. As of December 31, 2023 and 2022, there were 633,590 and 550,964 shares of common stock available for future issuance under the 2015 Plan, respectively.

Option Valuation Method

The fair value of a stock option is estimated using an option-pricing model that takes into account as of the grant date the exercise price and expected life of the option, the current price of the underlying stock and its expected volatility, expected dividends on the stock, and the risk-free interest rate for the expected term of the option. The Company has used the simplified method in calculating the expected term of all option grants based on the vesting period. Compensation costs related to share-based payment transactions are recognized in the financial statements upon satisfaction of the requisite service or vesting requirements and forfeitures are recorded as incurred.

The Company has elected to use the Black-Scholes option-pricing model. The Black-Scholes option-pricing model was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable rather than for use in estimating the fair value of stock options subject to vesting and transferability restrictions. Using the Black-Scholes option-pricing model, the weighted-average fair value of options granted during 2023 and 2022 was $1.29 and $2.47 per option, respectively. The aggregate fair value of options granted during 2023 and 2022 was $0.4 million and $2.1 million, respectively. The assumptions used to estimate fair value and the resulting grant date fair values are as follows:


	Employees						Non-employee
	Years Ended December 31,						Years Ended December 31,
	2023			2022			2023			2022
Weighted average expected volatility		74.77	%		73.80	%		80.12	%		74.20	%
Weighted average risk-free interest rate		3.98	%		2.45	%		3.89	%		3.18	%
Weighted average expected term (in years)		6.04			6.04			5.50			5.63

The activity for the 2009 Plan, 2014 Plan and 2015 Plan for the years ended December 31, 2023 is summarized as follows:


	Number of Shares			Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Life (in years)		Aggregate Intrinsic Value ($000)
Outstanding — December 31, 2022		1,740,308		$	12.21		6.16	$	—
Granted		303,000		$	1.87
Forfeited/expired		(175,513	)	$	10.21
Outstanding — December 31, 2023		1,867,795		$	10.72		6.10	$	184
Exercisable — December 31, 2023		1,320,943		$	13.92		5.03	$	53
Vested or expected to vest —December 31, 2023		1,867,795		$	10.72		6.10	$	184

The intrinsic values in the table above represent the total intrinsic value (the difference between the Company’s closing stock price as of December 31, 2023, and the exercise price multiplied by the number of options).

The total fair value of shares vested for both the years ended December 31, 2023 and 2022 was $0.7 million and $1.6 million, respectively.

As of December 31, 2023, there was approximately $1.0 million of total unrecognized compensation cost related to unvested options granted under the plans. That cost is expected to be recognized over a weighted-average period of 2.01 years.

Restricted stock unit ("RSU") activity under the 2014 Plan and 2015 Plan for the years ended December 31, 2023, is summarized as follows:


	Number of Shares			Weighted Average Grant Date Fair Value Per Share
Non-vested at December 31, 2022		633,270		$	5.29
Granted		1,929,575		$	1.79
Vested		(302,561	)	$	5.01
Forfeited		(373,910	)	$	2.62
Non-vested at December 31, 2023		1,886,374		$	2.28

The fair value of RSUs is based on the market price of the Company's common stock on the date of grant. RSUs generally vest 25% annually over a four year period from the date of grant. Upon vesting, the RSUs are net share settled to cover the required withholding tax with the remaining shares issued to the holder. The Company recognizes compensation expense for such awards ratably over the corresponding vesting period. As of December 31, 2023, there was approximately $2.6 million of total unrecognized compensation cost related to unvested RSU share-based compensation. That cost is expected to be recognized over a weighted-average period of 1.9 years.

2014 Employee Stock Purchase Plan

In February 2014, the Company’s board of directors adopted the 2014 Employee Stock Purchase Plan (“2014 ESPP”), which was subsequently ratified by the Company’s stockholders and became effective on May 2, 2014. The purpose of the 2014 ESPP is to provide means by which eligible employees of the Company and of certain designated related corporations may be given an opportunity to purchase shares of the Company’s common stock, and to seek and retain services of new and existing employees and to provide incentives for such persons to exert maximum efforts for the success of the Company.

In April 2023, the Company’s board of directors amended the 2014 ESPP, which was subsequently ratified by the Company’s stockholders and became effective on June 14, 2023. Common stock that may be issued under the ESPP Plan will not exceed 1,531,248 shares of common stock, which is the sum of: (i) the 4,779 shares of common stock originally approved; (ii) 26,469 shares of common stock that were added pursuant to the annual increase provision of the ESPP Plan between 2015 and 2023; and (iii) an additional 1,500,000 shares of common stock that were approved by our stockholders at the 2023 annual meeting of stockholders. The 2014 ESPP is intended to qualify as an “employee stock purchase plan” within the meaning of Section 423 of the Internal Revenue Code.

During the years ended December 31, 2023 and 2022, the Company issued 28,896 and 6,834 shares of common stock under the 2014 ESPP, respectively. During the years ended December 31, 2023 and 2022, the number of shares of common

stock available for issuance under the ESPP was increased by 1,502,941 and 2,941 shares, respectively. As of December 31, 2023 and 2022, there were 1,474,045 and zero shares of common stock available for future issuance under the 2014 ESPP, respectively.

Compensation Cost

The compensation cost that has been charged against income for stock awards under the 2009 Stock Option Plan, the 2014 Plan, the 2015 Plan, and the 2014 ESPP was $2.6 million and $3.5 million for the years ended December 31, 2023 and 2022, respectively. Additionally, during the year ended December 31, 2022, the Company recognized $0.2 million in stock based compensation associated with the Danforth warrant. The total income tax benefit recognized in the consolidated statements of operations for share-based compensation arrangements was $0 for the years ended December 31, 2023 and 2022, respectively. Cash received from options exercised was zero for the years ended December 31, 2023 and 2022, respectively.

Stock-based compensation expense related to stock options and stock awards is included in the following line items in the accompanying statements of operations (in thousands):


	Years Ended December 31,
	2023		2022

Fair Value Measurements

The carrying amounts of certain financial instruments, including cash and cash equivalents, accounts receivable, prepaid expenses and other current assets, accounts payable, and accrued expenses approximate their respective fair values due to the short-term nature of such instruments.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The Company evaluates its financial assets and liabilities subject to fair value measurements on a recurring basis to determine the appropriate level in which to classify them for each reporting period, pursuant to the policy described in Note 2. This determination requires significant judgments to be made. The following table summarizes the conclusions reached as of December 31, 2023 and 2022 for financial instruments measured at fair value on a recurring basis (in thousands):


			Fair Value Hierarchy Classification
	Balance		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)

Total liabilities	$	18,686		—		—	$	18,686

The Company measures cash equivalents at fair value on a recurring basis. The fair value of cash equivalents is determined based on “Level 1” inputs, which consist of quoted prices in active markets for identical assets. As of December 31, 2023, the cash and cash equivalents of $34.1 million and the restricted cash balances of $0.4 million and $0.2 million within short and long term on the balance sheet, respectively, sum to the total of $34.6 million as shown in the statement of cash flows. As of December 31, 2022, the cash and cash equivalents of $45.8 million and the restricted cash balances of $0.1 million and $0.2 million within short and long term on the balance sheet, respectively, sum to the total of $46.0 million as shown in the statement of cash flows.

Level 3 financial liabilities consist of the warrant liabilities for which there is no current market such that the determination of fair value requires significant judgment or estimation. Changes in fair value measurements categorized within Level 3 of the fair value hierarchy are analyzed each period based on changes in estimates or assumptions and recorded as appropriate. The Company uses the Black-Scholes option valuation model to value the Level 3 warrant liabilities at inception and on subsequent valuation dates. This model incorporates transaction details such as the Company’s stock price, contractual terms, maturity, risk free rates, as well as volatility. The unobservable input for all of the Level 3 warrant liabilities includes volatility. The historical and implied volatility of the Company, using its closing common stock prices and market data, is utilized to reflect future volatility over the expected term of the warrants. At December 31, 2023, the range and weighted average of the Level 3 volatilities utilized in the Black-Scholes model to fair value the warrant liabilities were 87.2% to 91.0% and 87.2%, respectively. At December 31, 2022, the range and weighted average of the Level 3 volatilities utilized in the Black-Scholes model to fair value the warrant liabilities were 101.8% to 113.0% and 102.1%, respectively. The Company utilizes a probability assessment to estimate the likelihood of vesting for the remaining Loan Agreement warrants and allocated the probability of occurrence percentage to the fair values calculated.

The Company uses the binomial lattice valuation model to value the Level 3 derivative liabilities at inception and on subsequent valuation dates. This model incorporates transaction details such as the Company’s stock price, contractual terms, dividend yield, risk-free rate, historical volatility, credit rating, market credit spread, and estimated effective yield. The unobservable inputs associated with the Level 3 derivative liability are adjusted equity volatility, market credit spread, and estimated yield. As of December 31, 2023, these inputs were 99.6%, 1,159 basis points, and 16.3%, respectively. As of December 31, 2022, these inputs were 68.5%, 1,495 basis points, and 19.3%, respectively. The senior convertible notes are initially fair valued using the binomial lattice model and with the straight debt fair value calculated using the discounted cash flow method. The residual difference represents the fair value of the embedded derivative liability and the fair value of the embedded derivative liabilities are reassessed using the binomial lattice valuation model on a quarterly basis.

A reconciliation of the beginning and ending balances for liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3) is as follows (in thousands):


	Warrant Liabilities
Balance – January 1, 2023	$	18,644
Loss adjustment to fair value		3,166
Balance – December 31, 2023	$	21,810

	Derivative Liability

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in the reports that we file or submit under the Securities Exchange Act of 1934 is (1) recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms and (2) accumulated and communicated to our management, including our principal executive officer and principal financial officer, to allow timely decisions regarding required disclosure.

As of December 31, 2023, our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934). Our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Our principal executive officer and principal financial officer have concluded based upon the evaluation described above that, as of December 31, 2023, our disclosure controls and procedures were effective at the reasonable assurance level.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). Our internal control over financial reporting is designed to provide reasonable assurance to our management and board of directors regarding the preparation and fair presentation of published financial statements. A control system, no matter how well designed and operated, can only provide reasonable, not absolute, assurance that the objectives of the control system are met. Because of these inherent limitations, management does not expect that our internal controls over financial reporting will prevent all error and all fraud. Under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control—Integrated Framework (2013 Framework) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation under the framework in Internal Control—Integrated Framework, our management concluded that our internal control over financial reporting was effective as of December 31, 2023.

During the quarter ended December 31, 2023, there have been no changes in our internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15(d)-15(f) promulgated under the Securities Exchange Act of 1934, that have materially affected, or are reasonably likely to materially affect, our internal control.
