Forward-looking statements are based on our management’s beliefs and assumptions and on information currently available to our management. In some cases, you can identify forward-looking statements by terms such as “may,” “will,” “should,” “could,” “would,” “expect,” “plan,” “anticipate,” “believe,” “estimate,” “project,” “predict,” “potential” and similar expressions intended to identify forward-looking statements. These statements involve known and unknown risks, uncertainties and other factors which may cause our actual results, performance, time frames or achievements to be materially different from any future results, performance, time frames or achievements expressed or implied by the forward-looking statements. We discuss many of these risks, uncertainties and other factors in this Annual Report on Form 10-K in greater detail under the heading “Risk Factors.” Given these risks, uncertainties and other factors, you should not place undue reliance on these forward-looking statements. Also, these forward-looking statements represent our estimates and assumptions only as of the date of this filing. You should read this Annual Report on Form 10-K completely and with the understanding that our actual future results may be materially different from what we expect. We hereby qualify our forward-looking statements by our cautionary statements. Except as required by law, we assume no obligation to update these forward-looking statements publicly, or to update the reasons actual results could differ materially from those anticipated in these forward-looking statements, even if new information becomes available in the future. RISK FACTOR SUMMARY 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 these risk factors: Risks Relating to Our Financial Condition and Need for Additional Capital • • • We have never been profitable, we have no products approved for commercial sale, and to date we have not generated any revenue from product sales. As a result, our ability to curtail our losses and reach profitability is unproven, and we may never achieve or sustain profitability. 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. 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 in an event of default, which could have a materially adverse effect on our business. 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, and without regulatory approval we will not be able to market ibrexafungerp. Regulatory approval is a lengthy, expensive and uncertain process, and there is no guarantee that ibrexafungerp will ultimately be approved by the FDA. 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. We have limited experience in conducting clinical trials and have only submitted one 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. If ibrexafungerp 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. If resistance to ibrexafungerp develops quickly or cross-resistance with echinocandins becomes more common, our business will be harmed. 3 • • • • • If we are unable to obtain regulatory approval of both the oral and IV formulations of ibrexafungerp, ibrexafungerp may not achieve broad market acceptance and sales will be limited. Our 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. We have never marketed a drug before, and if we are unable to establish an effective sales force and marketing infrastructure or enter into acceptable third- party sales and marketing or licensing arrangements, we may not be able to successfully commercialize ibrexafungerp and any future product candidates we may seek to develop. We expect that ibrexafungerp 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. Reimbursement decisions by third-party payors may have an adverse effect on pricing and market acceptance in the United States. If there is not sufficient reimbursement for our products, it is less likely that our products will be purchased by patients and/or providers. Risks Related to Our Dependence on Third Parties • • We are dependent on our existing third-party collaborations for drug development and to commercialize ibrexafungerp, and if these third-parties do not perform well under these collaborations, or our prospects may be harmed. 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. Risks Relating to Our Intellectual Property • • • 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. It is difficult and costly to protect our proprietary rights, and we may not be able to ensure their protection. 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. Risks Related to Employee Matters and Managing Growth • • We may not be able to manage our business effectively if we are unable to attract and retain key personnel. We may need to expand our operations and increase the size of our company, and we may experience difficulties in managing growth. Other Risks Relating to Our Business • • • • • • We 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. Our internal computer systems, or those used by our contract research organizations or other contractors or consultants, may fail or suffer security breaches. Our insurance policies are expensive and protect us only from some business risks, which will leave us exposed to significant uninsured liabilities. Our research and development activities could be affected or delayed as a result of possible restrictions on animal testing. U.S. and foreign privacy and data protection laws and regulations may impose additional liabilities on us. Our business could be adversely affected by the COVID-19 outbreak, in regions where we or third parties on which we rely have significant concentrations of clinical trial sites, manufacturing facilities, or other business operations. 4 Risks Relating to Owning Our Common Stock • • • The market price of our common stock may be highly volatile. 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. Sales of our common stock to Aspire Capital may cause substantial dilution to our existing stockholders and the sale of the shares of our common stock acquired by Aspire Capital could cause the price of our common stock to decline. REVERSE STOCK SPLIT On July 16, 2020, we implemented a 1-for-10 reverse stock split of our common stock and decreased the number of authorized shares of our common stock from 250,000,000 shares to 100,000,000 shares. All share and per share amounts presented in this Annual Report on Form 10-K have been retroactively adjusted for the reverse stock split. ITEM 1. BUSINESS Overview SCYNEXIS, Inc. is pioneering innovative medicines to potentially help millions of patients worldwide in need of new options to overcome and prevent difficult-to-treat and drug-resistant infections. We are developing our lead product candidate, ibrexafungerp, as a broad-spectrum, intravenous (IV)/oral agent for multiple fungal indications in both the community and hospital settings. In December 2020, we announced that we had received the acceptance letter from the U.S. Food and Drug Administration (FDA) for our New Drug Application (NDA) for oral ibrexafungerp for the treatment of vulvovaginal candidiasis (VVC, also known as vaginal yeast infection) with a Prescription Drug User Fee Act (PDUFA) action goal date of June 1, 2021. The FDA has conditionally approved “Brexafemme” as the brand name for oral ibrexafungerp for vaginal yeast infections. We are also continuing late-stage clinical development for the prevention of recurrent VVC as well as the treatment of life-threatening invasive fungal infections in hospitalized patients. Ibrexafungerp, the first representative of a novel class of antifungal agents called triterpenoids and designated by the suffix “-fungerp”, is a structurally distinct glucan synthase inhibitor and has shown in vitro and in vivo activity against a broad range of human fungal pathogens such as Candida and Aspergillus species, including multidrug- resistant strains, as well as Pneumocystis, Coccidioides, Histoplasma and Blastomyces species. Candida and Aspergillus species are the fungi responsible for approximately 85% of all invasive fungal infections in the United States (U.S.) and Europe. To date, we have characterized the antifungal activity, pharmacokinetics, and safety profile of the oral and IV formulations of ibrexafungerp in multiple in vitro, in vivo, and clinical studies. The FDA has granted Qualified Infectious Disease Product (QIDP) and Fast Track designations to ibrexafungerp for the indications of VVC (including the treatment of VVC episodes and 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. These designations may provide us with additional market exclusivity and expedited regulatory paths. 5 Our Platform of Indications Oral Ibrexafungerp Development Program We continue to actively advance our clinical programs, leveraging the potential of ibrexafungerp to be a suitable treatment for multiple indications with significant unmet medical needs and considerable commercial opportunities. The following illustration summarizes the status of the indications for oral ibrexafungerp currently being pursued, and the potential NDA approval for the treatment of VVC in June 2021: Vaginal Yeast Infections — Our most advanced stage of clinical development, targeting both treatment of VVC and prevention of recurrent VVC. The Phase 3 registration program for the treatment of VVC and prevention of recurrent VVC comprises three multi-center, randomized, double-blind, placebo- controlled trials designed according to FDA guidance to demonstrate superiority of oral ibrexafungerp vs. placebo, as detailed below: • Treatment of VVC (VANISH Phase 3 Program) In December 2020, we announced that we had received the acceptance letter from the FDA for our NDA for ibrexafungerp for the treatment of VVC, also known as vaginal yeast infection, with a PDUFA action goal date of June 1, 2021. The NDA is supported by positive results from two Phase 3, randomized, double-blind, placebo-controlled, multi-center studies (VANISH-303 and VANISH-306), in which oral ibrexafungerp demonstrated statistically superior efficacy and a favorable tolerability profile in women with VVC. Additionally, the FDA has communicated that it is not currently planning to hold an advisory committee meeting to discuss the application. The FDA has conditionally approved “Brexafemme” as the brand name for ibrexafungerp for the treatment of vaginal yeast infections. • Prevention of Recurrent VVC In March 2021, we completed enrollment in the CANDLE study, a Phase 3, multi-center, randomized, double-blind, placebo-controlled trial designed to evaluate the efficacy and safety of oral ibrexafungerp compared to placebo in preventing an acute episode in women with recurrent VVC (defined at least three or more episodes of VVC in the past 12 months, including the episode at screening). We expect the last-patient/last-visit for the CANDLE study by the end of 2021. As a result of the COVID-19 pandemic, our timelines for reaching our targeted enrollment size in the CANDLE study were slightly extended and we now anticipate both top-line data and a potential supplemental NDA submission for the prevention of recurrent VVC in the first half of 2022, resulting in a potential approval in late 2022. The CANDLE study, which is being conducted in female patients age 12 years and older living with recurrent VVC, enrolled 441 subjects from approximately 50 global centers. The primary endpoint of the study is efficacy as measured by the percentage of patients with no recurrences of an acute episode of VVC, up through their test-of-cure (TOC) evaluation at week 24. Secondary endpoints of the study include evaluation of VVC recurrences at other time points up to week 36, time to first recurrence, mycological eradication and quality of life assessments. All patients in the CANDLE study initially received three doses of oral fluconazole to treat their acute VVC episode present at screening. Patients who responded to oral fluconazole for their acute VVC episode were enrolled in the prevention of recurrence 6 phase of the study and randomized to oral ibrexafungerp (300mg BID for one day) or placebo, given one day per month for six months. Patients who failed to sufficiently respond to fluconazole treatment for their acute VVC episode were included in a nested open-label sub-study, in which they were offered a single day of oral ibrexafungerp treatment (300mg BID) for their unresolved VVC infection. The CANDLE study is being conducted in accordance with an agreement with the FDA under a Special Protocol Assessment (SPA) on the design, trial population, endpoints and statistical analysis of the study. This SPA provides agreement with the FDA that the Phase 3 protocol design adequately addresses efficacy objectives that, if met, would form the primary basis of a regulatory submission for approval of oral ibrexafungerp for the prevention of recurrent VVC, an indication with no FDA-approved therapies. Refractory Invasive Fungal Infections (rIFI) —Potential for streamlined development pathway. Enrollment is ongoing in our rIFI program, which comprises two open-label Phase 3 studies (FURI and CARES) designed to support a potential future NDA submission through the Limited Population Pathway for Antibacterial and Antifungal Drugs (LPAD). In March 2021, we announced that a Data Review Committee (DRC) of independent experts assessed the efficacy of oral ibrexafungerp in a third cohort of 33 patients from the FURI study and a first cohort of ten patients from the CARES study. The third interim analysis of the FURI study showed that antifungal activity was consistently positive across all interim analyses with oral ibrexafungerp showing clinical benefit in 30 out 33 patients, and no patients with progression of disease. On an aggregate basis, oral ibrexafungerp showed clinical benefits in 86.5% of patients (64 out 74), with 46 patients achieving a complete or partial response and 18 patients achieving a stable disease response. Of the 74 treated patients, only five did not respond to ibrexafungerp treatment, one patient died of an underlying condition unrelated to the treatment or fungal infection, and four patients were considered indeterminate. Analysis of the CARES study found that 80% (8 out 10) patients with invasive candidiasis and candidemia due to Candida auris experienced a complete response, one patient died of an underlying condition unrelated to the treatment or fungal infection and one patient was considered indeterminate. Oral ibrexafungerp exhibited a positive safety profile and was well-tolerated, with gastrointestinal issues cited as the most common treatment-related adverse events. There were no safety signals warranting changes to the studies. Below is the summary of the aggregate interim analysis for FURI and CARES: Global Response Complete or Partial Response or Clinical Improvement Stable Disease Total No Response Indeterminate Aggregate (FURI) n=74 (%) CARES n=10 (%) Aggregate (FURI+CARES) n=84 (%) 46 (62) 18 (24) 64 (87) 6 (8) 4 (5) 8 (80) 0 (0) 8 (80) 1 (10) 1 (10) 54 (64) 18 (21) 72 (86) 7 (8) 5 (6) The FURI study is evaluating oral ibrexafungerp as a salvage treatment in patients with a variety of difficult-to-treat mucocutaneous and invasive fungal infections that are refractory to or intolerant of current standards of care, or require a non-azole oral step-down therapy for treatment of azole-resistant species. The CARES study is focused on hospitalized patients with invasive candidiasis caused by the multidrug-resistant Candida auris organism, which is associated with high mortality, and the interim analysis was the first clinical trial data of an investigational treatment against infections caused by Candida auris. Candida auris has been recently declared an “Urgent Threat” to public health by the Centers for Disease Control and Prevention (CDC) in its report, Antibiotic Resistance Threats in the United States, 2019, as it can be multidrug-resistant, has resulted in high mortality rates (up to 60%), and can be spread from patients (and surfaces) to patients, resulting in hospital outbreaks. The CARES study is intended to provide rapid access to oral ibrexafungerp for patients suffering from this life-threatening infection. The open-label designs of the FURI and CARES studies permit evaluation of the data on an interim basis to further inform subsequent regulatory steps of the development program. We believe that compelling data from the FURI and/or CARES studies could allow ibrexafungerp to become eligible for the regulatory LPAD, potentially resulting in an NDA submission based on streamlined development. The LPAD was established under the 21st Century Cures Act of 2016, and FDA draft guidance issued in June 2019 suggests smaller, shorter or fewer clinical trials may be appropriate to support approval to treat a serious or life-threatening infection in a limited population with unmet needs. We plan to continue to advance enrollment in the FURI and CARES studies, both in the U.S. and globally. Positive clinical findings from these studies have so far reinforced the potential role of oral ibrexafungerp as a novel therapy to combat severe and difficult-to-treat fungal infections, including multidrug-resistant Candida auris. Invasive Pulmonary Aspergillosis—Ibrexafungerp in combination with standard of care may represent a significant opportunity to improve outcomes for this high- mortality infection. Based on promising pre-clinical data from combination use of ibrexafungerp with SoC vs. Aspergillus spp., we are conducting a Phase 2 study (SCYNERGIA study) of oral ibrexafungerp in combination with voriconazole (SoC) in patients 7 with IA. 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 believe that ibrexafungerp’s broad activity against Aspergillus spp., including azole-resistant strains, along with its minimal drug-drug interactions, high tissue penetration into the lungs, and oral formulation allowing for long-term administration, may make it an ideal candidate for use as combination therapy to provide improved outcomes vs. SoC. Pending successful completion of this study, we anticipate top-line data by the end of 2021. IV Ibrexafungerp Development Program Based on promising pre-clinical data of our liposomal IV formulation of ibrexafungerp, we are conducting a Phase 1, randomized, double-blind, placebo-controlled study to evaluate the safety, tolerability, and pharmacokinetics of the IV liposomal formulation of ibrexafungerp in healthy subjects. The study is being conducted in South Africa and dosing started in March 2021. We expect to provide further updates as the study advances. Key Milestones We believe we will potentially achieve the following key milestones in the next 12 months: • receive approval of ibrexafungerp for the treatment of VVC by the FDA on the expected PDUFA target action date of June 1, 2021; • commercially launch ibrexafungerp in the U.S. for the treatment of vaginal yeast infections, if approved, in the second half of 2021; • report development updates on our Phase 1 study of the IV liposomal formulation of ibrexafungerp; • provide both top-line data of the Phase 3 CANDLE study and a potential supplemental NDA submission for the prevention of recurrent VVC in the first half of 2022 with a potential approval in late 2022; and • provide top-line data of the Phase 2 SCYNERGIA study by the end of 2021. Our Strategy Key elements of our strategy include: • to further develop ibrexafungerp and obtain regulatory approval in major commercial markets for our key initial indications: treatment of VVC, prevention of recurrent VVC, invasive candidiasis and invasive aspergillosis; • to commercialize ibrexafungerp for selected indications in the U.S. through a dedicated commercial team, including field force; • to contract with commercial partners to develop and commercialize ibrexafungerp outside of the U.S.; • to assess external opportunities for in-licensing to expand our development pipeline and add products for commercialization; and • to leverage our strong scientific team to pursue the development of other internal proprietary compounds. Market Opportunity Vaginal Yeast Infections 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 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 8 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. Currently, there are only azole class treatments available for women suffering from VVC with no 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 ibrexafungerp 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 it every year, it is still an under-appreciated, under-reported, and under-served women’s health condition. There are over 18 million prescriptions written for VVC in the U.S. annually, all of which belong to a single drug class, the azoles. Additionally, of the 9.5 million women in the U.S. who received a prescription for VVC in the previous year, about 40% of them required multiple prescriptions, illustrating that many patients’ symptoms are not adequately addressed by existing azole treatments. There has been no new oral treatment for VVC in over 25 years, and we believe health care providers are eager for a novel oral alternative to treat their patients. Ibrexafungerp, if approved, would be the first and only oral, non-azole treatment for vaginal yeast infections. We believe that ibrexafungerp’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, will differentiate it from competing products. Invasive Aspergillosis 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. Invasive Candidiasis / rIFI 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 Candida species, 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% 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. 9 Ibrexafungerp Target Product Profile 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 species, including multidrug-resistant strains, as well as Pneumocystis, Coccidioides, Histoplasma and Blastomyces species. 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. Ibrexafungerp has unique attributes that define its potential to address significant unmet medical needs and provide considerable commercial opportunities, including: • oral bioavailability, unlike other glucan synthase inhibitors, allowing for convenient long-term outpatient use; • broad activity against Candida, Aspergillus, Pneumocystis, Coccidioides, Histoplasma and Blastomyces strains; • distinct chemical structure from other glucan synthase inhibitors, providing a unique spectrum of activity and pharmacokinetic profile; • activity against azole-resistant and most echinocandin-resistant Candida strains, including Candida auris and multidrug-resistant strains; • activity against azole-resistant Aspergillus strains; • fungicidal (i.e., killing the fungi) capabilities against Candida species compared to azoles, which are fungistatic (i.e., only inhibiting the growth of fungi); • high tissue penetration, allowing high concentrations in the organs commonly affected by fungal infections; • generally well tolerated with over 1,200 subjects and patients exposed; and • 20-hour half-life with a low risk of drug-drug interactions. We believe that ibrexafungerp, if approved, has the potential to address significant gaps with commercially available therapies in the following indications: • treatment of vaginal yeast infections, including prevention of recurrent infections; • invasive candidiasis (including resistant infections); • invasive aspergillosis (including resistant infections); and • refractory invasive fungal infections. In the future, we 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. Given our stage of development, we have not yet established an operational commercial organization or distribution capabilities and we are in the process of assessing our global commercial strategy. Given the June 1, 2021 PDUFA date for the treatment VVC indication, we have been rapidly building the commercial organization including talent, operational infrastructure, processes and IT and data capabilities. We have also been putting in place an ecosystem of key sales, marketing, market access, distribution, and patient support partners to ensure an agile, omnichannel commercial model that will provide a positive experience for both patients and healthcare providers. For the treatment and prevention of vaginal yeast infections, we anticipate that prescribing physicians will mostly be obstetricians, gynecologists, and nurse practitioners. In February 2021, we partnered with a third-party commercial sales organization, Amplity, Inc., for the potential upcoming commercial launch of ibrexafungerp for the treatment of VVC in the U.S. We will utilize Amplity’s commercial execution expertise and resources for sales force, remote engagement, training, market access and select operation services. Amplity is deferring a portion of its direct service costs in the first two years (2021 and 2022), up to a cap, which we will repay over three years starting in 2023. Amplity has the potential to earn a performance-based success fee, up to a cap, in the 2023-2025 timeframe by exceeding certain revenue targets. Each party retains the right to terminate the agreement upon notice to the other party. 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. For these indications, we intend to form our own focused hospital-based field force to target physicians in the U.S. Outside of the U.S., subject to obtaining necessary marketing approvals, we will likely seek to commercialize ibrexafungerp through distribution or other collaboration arrangements. 10 Competition for Ibrexafungerp 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. Pfizer also markets the echinocandin Eraxis® (anidulafungin) and Astellas markets the echinocandin Mycamine® (micafungin); 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. Further, we expect that product candidates currently in clinical development may represent significant competition, if approved. These include the azole Oteseconazole (VT-1161) being developed by Mycovia Pharmaceuticals, Inc., formerly Viamet Pharmaceuticals, Inc. (assets acquired by NovaQuest Capital Management, LLC), the long- acting IV echinocandin Rezafungin (CD101) being developed by Cidara Therapeutics, Inc., 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 sparse 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. Our commercial opportunity could be reduced or eliminated if our 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 may develop. Our competitors also may obtain FDA, or other regulatory, approval for their products more rapidly than we may obtain approval for ours. In addition, our ability to compete 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. Manufacturing and Supply of Ibrexafungerp We have agreements with external vendors that are capable of supplying drug substance and of producing drug product to support ongoing and planned clinical trials, as well as for planned commercial launch. However, 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. We expect to continue to rely on either existing or alternative third-party manufacturers to supply ibrexafungerp for ongoing and planned clinical trials and for commercial production. Ibrexafungerp is a semi-synthetic compound. Thus, the manufacturing process for ibrexafungerp involves fermentation and synthetic chemical steps. The synthetic process does not require any specialized equipment and uses readily sourced intermediates. At commercial scale, we expect cost of goods for ibrexafungerp to be similar to that of other small molecule drugs. We have negotiated agreements with our primary contract manufacturers to produce both drug product and drug substance for our current clinical and commercial needs. In the future, we plan to qualify secondary suppliers to establish a secure supply chain to support commercialization. We estimate our supplies on hand as well as those we plan to produce for the oral formulation of ibrexafungerp are sufficient to supply our ongoing and planned clinical trials as well as our anticipated commercial launch for the treatment of VVC, if approved, in the second half of 2021. Manufacture of additional supplies of ibrexafungerp drug substance is planned 11 to support any further optimization of either the oral or IV formulations, if needed. Additional batches of both oral and IV ibrexafungerp drug product will be manufactured as needed to support the subsequent stages of our clinical development plan and commercial supply requirements. 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. The primary third-party vendors with which we have agreements in place to support manufacturing and supply both for clinical development and commercial launch 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 for late-stage clinical and commercial use. 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: Merck 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 3 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., anticipated 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. Hansoh In February 2021, we entered into an Exclusive License and Collaboration Agreement (the 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 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 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. 12 R-Pharm 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. Government Regulation Government Regulation 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. U.S. Drug Approval Process In the United States, the FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act (FDCA), and implementing 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: • completion of preclinical laboratory tests, animal studies and formulation studies in compliance with the FDA’s good laboratory practice (GLP) regulations; • submission to the FDA of an investigational new drug application (IND) which must become effective before human clinical trials may begin; • approval by an independent institutional review board, or IRB, at each clinical site before each trial may be initiated; • performance of adequate and well-controlled human clinical trials in accordance with good clinical practice (GCP) to establish the safety and efficacy of the proposed drug for each indication, subject to on-going IRB review; • submission to the FDA of an NDA; • satisfactory completion of an FDA advisory committee review, if applicable; • satisfactory completion of an FDA inspection of the manufacturing facility or facilities at which the product is produced to assess compliance with current Good manufacturing practice (cGMP) regulations and guidance, and to assure that the facilities, methods and controls are adequate to preserve the drug’s identity, strength, quality and purity; and • FDA review and approval of the NDA. 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 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 13 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 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). GAIN Act 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 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 Qualified Infectious Disease Product (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: • caused by an antifungal resistant pathogen, including novel or emerging infectious pathogens; or • qualifying pathogens listed by the FDA in accordance with the GAIN Act. Fast Track Designation 14 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. Post Approval Requirements 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 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. Qualified Infectious Disease Product Exclusivity 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 15 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. Other U.S. Healthcare Laws and Compliance Requirements In the United States our activities are potentially 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 (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, 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. Foreign Regulation 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. Pharmaceutical Coverage, Pricing and Reimbursement and Health Care Reform Our ability to commercialize 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. 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 Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010, or collectively, 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, the United States Supreme Court is currently reviewing the constitutionality of the Affordable Care Act. There also has been increasing legislative and enforcement interest in the United States with respect to drug pricing practices. Specifically, there have been several recent executive orders, Congressional inquiries and proposed federal legislation designed to, among other things, bring more transparency to drug pricing, reduce the cost of prescription drugs under Medicare, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drugs. Further, it is possible that additional governmental action is taken in response to the COVID-19 pandemic. Intellectual Property 16 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, 2021, we are the owner of 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 2035. Of these patents, four U.S. patents relate to ibrexafungerp. We are actively pursuing six U.S. patent applications and many non-U.S. patent applications in multiple jurisdictions worldwide. Ibrexafungerp is protected by an issued composition of matter patent (U.S. Patent No. 8,188,085) in the United States, which expires in 2030, and we will have ten to twelve years of regulatory exclusivity in the U.S. Based on our current development plan, we believe that an additional term of up to five years for the ibrexafungerp composition of matter U.S. patent may result from the patent term extension provision of the Drug Price Competition and Patent Term Restoration Act of 1984 (the Hatch- Waxman Act). The composition of matter is covered by a patent in more than 60 jurisdictions, with 10 patent applications pending, worldwide. Three patents related to ibrexafungerp salts and polymorphs, including the citrate salt currently under development, have issued, with expiration expected in 2035. 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.” Employees As of March 1, 2021, we had 38 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. Corporate Information 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. ITEM 1A. RISK FACTORS 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. Risks Relating to Our Financial Condition and Need for Additional Capital We have never been profitable, we have no products approved for commercial sale, and to date we have not generated any revenue from product sales. As a result, our ability to curtail our losses and reach profitability is unproven, and we may never achieve or sustain profitability. We are not profitable and do not expect to be profitable in the foreseeable future. We have incurred net losses in each year since our inception, including a net loss of $55.2 million for the year ended December 31, 2020. As of December 31, 2020, we had an accumulated deficit of approximately $326.6 million. On a prospective basis, our strategic focus, along with the commitment of our financial resources, will be directed towards the development and potential commercialization of ibrexafungerp, our lead product candidate. We had cash and cash equivalents of $93.0 million as of December 31, 2020. Based upon our existing operating plan, we believe that our existing cash and cash equivalents, the sale of a portion of our New Jersey NOLs, the upfront payment from Hansoh, and anticipated sales of Brexafemme will enable us to fund our operating requirements into 2023, although there can be no assurances that we will be able to continue our operations on a long-term basis. We have suffered substantial losses from operations since inception and will require additional financing. We expect to continue to incur significant expenses and increasing 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: 17 • • • • • • • • continue the development of ibrexafungerp for treatment of multiple indications; conduct ongoing and initiate new clinical trials for ibrexafungerp; seek marketing approvals for ibrexafungerp; establish a sales, marketing and distribution infrastructure to commercialize any products for which we may obtain marketing approval; maintain, expand and protect our intellectual property portfolio; hire additional clinical, quality control and scientific personnel; maintain and create additional infrastructure to support our operations as a public company; and develop in-house product candidates or seek to in-license product candidates from third-parties. 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, an adverse effect on our stockholders’ equity, financial position and working capital. 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: • • • • • • • • • • • • • the costs associated with developing ibrexafungerp, which are difficult for us to predict; any delays in regulatory review and approval of ibrexafungerp; delays in the timing of submission of any new drug application, or NDA, or supplement thereto, as well as commencement, enrollment and the timing of clinical testing, of ibrexafungerp or any other product candidates we may seek to develop; our ability to commercialize product candidates, both in the United States and overseas, if we are able to obtain regulatory approval to do so; the costs associated with obtaining and maintaining regulatory approval and ongoing company compliance and product compliance for ibrexafungerp; market acceptance of ibrexafungerp and any future product candidates we may seek to develop; changes in regulations and regulatory policies; competition from existing products or new products that may emerge; the ability of patients or healthcare providers to obtain coverage of, or sufficient reimbursement for, any products we are able to develop; our ability to establish or maintain collaborations, licensing or other arrangements; costs related to, and outcomes of, potential litigation; potential product liability claims; and potential liabilities associated with hazardous materials. 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. 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. Based upon our existing operating plan, we believe that our existing cash and cash equivalents, the sale of a 18 portion of our New Jersey NOLs, the upfront payment from Hansoh, and anticipated sales of Brexafemme will enable us to fund our operating requirements into 2023; provided, however, that changing circumstances may cause us to consume cash more rapidly than we currently anticipate. 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 ibrexafungerp and any future 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 and commercialize ibrexafungerp and any future 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: • • • significantly delay, scale back or discontinue the development or commercialization of ibrexafungerp and any future product candidates we may seek to develop; seek strategic alliances for research and development programs at an earlier stage than otherwise would be desirable or on terms that are less favorable than might otherwise be available; or relinquish or license on unfavorable terms our rights to any product candidates that we otherwise would seek to develop or commercialize ourselves. 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 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, and on April 9, 2020, we entered into a senior convertible note purchase agreement with Puissance pursuant to which we issued and sold to Puissance $10 million of our 6.0% senior convertible notes due 2026. 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. 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, and without regulatory approval we will not be able to market ibrexafungerp. Regulatory approval is a lengthy, expensive and uncertain process. Our ability to generate significant revenue related to ibrexafungerp sales will depend on the successful development and regulatory approval of ibrexafungerp. We expect that the earliest that we could obtain regulatory approval of ibrexafungerp and commence commercialization of ibrexafungerp will be in June 2021, if at all. We currently have no products approved for sale and we cannot guarantee that we will ever have 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 from the FDA. Although we have submitted an NDA for ibrexafungerp for the treatment of VVC, have not yet received regulatory approval of our NDA for this indication. We have not submitted an NDA for ibrexafungerp for the prevention of recurrent VVC or 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 19 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, as we expect will occur for our NDA for ibrexafungerp for the treatment of VVC, 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: • • • • • • • • • • inability to reach agreements on acceptable terms with prospective clinical research organizations, or CROs, and trial sites, the terms of which can be subject to extensive negotiation and may vary significantly among different CROs and trial sites; difficulty identifying and engaging qualified clinical investigators; regulatory objections to commencing a clinical trial or proceeding to the next phase of investigation, including inability to reach agreement with the FDA or non-U.S. regulators regarding the scope or design of our clinical trials or for other reasons such as safety concerns that might be identified during preclinical development or early stage clinical trials; inability to identify and maintain a sufficient number of eligible trial sites, many of which may already be engaged in other clinical trial programs, including some that may be for the same indication as our product candidates; withdrawal of clinical trial sites from our clinical trials as a result of changing standards of care; inability to obtain institutional review board (or ethics review committee) approval to conduct a clinical trial at prospective sites; difficulty identifying, recruiting and enrolling eligible patients to participate in clinical trials for a variety of reasons, including meeting the enrollment criteria for our study and competition from other clinical trial programs for the same indication as product candidates we seek to commercialize; inability to retain patients in clinical trials due to the treatment protocol, personal issues, side effects from the therapy or lack of efficacy; inability to produce and/or obtain in a timely manner sufficient quantity of our products to satisfy the requirements of the clinical trials; inability to enroll patients, or slow down in the rate of enrolling patients, in clinical trials due to unforeseen natural disasters, public health crises, political crises and other catastrophic events or other events outside of our control, such as the recent emergence and spread of COVID-19, a coronavirus, which may cause participants to not want to participate in these trials or otherwise have any unnecessary contact with the medical community; and 20 • inability to obtain sufficient funding to commence a clinical trial. 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: • • • • failure by us, CROs or clinical investigators to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols; failed inspection of the clinical trial operations or trial sites by the FDA or other regulatory authorities; safety or efficacy issues or any determination that a clinical trial presents unacceptable health risks. During an extension of our Phase 1 program for the intravenous formulation in healthy volunteers, aimed to expand the safety margin that would allow greater flexibility of dosing options in patients, we observed adverse events secondary to thrombi formation at site of IV infusion; or lack of adequate funding to continue the clinical trial due to unforeseen costs resulting from enrollment delays, requirements to conduct additional trials and studies, increased expenses associated with the services of our CROs and other third parties, or other reasons. 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 have limited experience in designing clinical trials and 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 our NDA for ibreaxfungerp for the treatment of VVC will be approved, or 21 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 limited experience in conducting clinical trials and have only submitted one 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. Merck completed seven Phase 1 clinical trials of ibrexafungerp and we have completed 13 Phase 1 clinical trials, four Phase 2 trials, and have initiated five Phase 3 trials, two of which have been completed and three of which are ongoing. We are planning to conduct additional Phase 1, Phase 2, and Phase 3 clinical trials of ibrexafungerp. 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 five Phase 3 clinical trials, and we have only submitted one NDA. 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 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 although we have PDUFA date for our NDA submission for ibrexafungerp for the treatment of VVC, we cannot predict the review time for any other 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 ibrexafungerp 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 ibrexafungerp 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: • • • • • • • limitations or warnings contained in the FDA-approved labeling; changes in the standard of care for the targeted indications; limitations in the approved indications; availability of alternative therapies with potentially advantageous results, or other products with similar results at similar or lower cost, including generics and over-the-counter products; lower demonstrated clinical safety or efficacy compared to other products; occurrence of significant adverse side effects; ineffective sales, marketing and distribution support; 22 • • • • • • lack of availability of coverage and adequate reimbursement from governmental health care programs, managed care plans and other third-party payors; timing of market introduction and perceived effectiveness of competitive products; lack of cost-effectiveness; adverse publicity about our product candidates or favorable publicity about competitive products; lack of convenience and ease of administration; and potential product liability claims. If ibrexafungerp 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 in the event that we are able to obtain FDA approval of 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. If we are unable to obtain regulatory approval of both the oral and IV formulations of ibrexafungerp, ibrexafungerp may not achieve broad market acceptance and sales will be limited. Current treatment regimens for invasive fungal infections typically involve initial administration of treatments as an IV infusion, with a switch to an oral formulation of the same or a similar medication to complete the course of treatment on an out-patient basis. We believe that providing both the IV and oral formulations will be beneficial to doctors who prefer to start treatment of patients in a hospital setting with an IV therapy and then switch them to an oral formulation of the same medication. If we are unable to successfully develop and achieve regulatory approval for either the oral or IV formulation of ibrexafungerp, our lead product candidate may not achieve, or may be delayed in achieving, broad market acceptance and sales will be limited. Our 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. Although we have a PDUFA date for our NDA submission for ibrexafungerp for the treatment of VVC, it is impossible to predict when or if ibrexafungerp for other indications or any other product candidate we may seek to develop will prove effective or safe, or whether we will receive marketing approval for ibrexafungerp for the treatment of VVC or other indications, or 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 in a Phase 1 study. These events were reported to FDA as 15-day alert reports because they were unexpected and required anticoagulant therapy. 23 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. On March 2, 2017, we announced that the FDA had placed a clinical hold on our IV formulation, instructing us to hold the initiation of any new clinical studies with our IV formulation until the FDA completes a review of all available pre-clinical and clinical data of the IV formulation of ibrexafungerp. In January 2018, we announced encouraging pre-clinical results for the prototype liposomal IV formulation of ibrexafungerp, showing improved local tolerability profile at the infusion site in head-to-head pre- clinical evaluations with the cyclodextrin-based IV formulation. In August 2018, we announced that as part of our development plans, the process for the liposomal formulation was transferred for scale-up purposes at a manufacturing site intended to provide clinical supplies. Additional preclinical evaluations were performed with the scaled-up formulation, which unexpectedly revealed differences in tolerability at the injection site, delaying advancement of the IV product into human trials. As it is generally recognized that changes to manufacturing processes and/or scale-up can impact the characteristics of drug products, particularly for more technically complex formulations such as liposomal products, we are currently working with our vendors and CMC experts to enable us to resume the pre-IND pre-clinical activities for the IV formulation of ibrexafungerp in the U.S. If the FDA does not permit us to initiate new clinical studies with our IV formulation, we will not be able to develop and commercialize an IV formulation of ibrexafungerp, which would harm our business prospects. We are currently conducting a Phase 1, randomized, double-blind, placebo-controlled study to evaluate the safety, tolerability, and pharmacokinetics of the IV liposomal formulation of ibrexafungerp in healthy subjects. The study is being conducted in South Africa and dosing started in March 2021. 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 Phase 1 clinical trial in South Africa and any future 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. Even if ibrexafungerp or any future product candidate we may seek to develop receives marketing approval, we or others may subsequently identify undesirable or unacceptable side effects caused by these products, in which case: • • • • • • • regulatory authorities may require the addition of labeling statements, specific warnings, precautions, contraindications or field alerts to physicians and pharmacies; we may be required to change the way the product is administered, conduct additional clinical trials or change the labeling of the product; we may have limitations on how we promote the product; sales of the product may decrease significantly; regulatory authorities may require us to take our approved product off the market; we may be subject to litigation or product liability claims; and our reputation may suffer. 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 have never marketed a drug before, and if we are unable to establish an effective sales force and marketing infrastructure or enter into acceptable third-party sales and marketing or licensing arrangements, we may not be able to successfully commercialize ibrexafungerp and any future product candidates we may seek to develop. We currently do not have any sales, distribution and marketing capabilities, the development of which will require substantial resources and will be time consuming. The costs incurred in the development of these capabilities, either internally or through a third-party contract sales organization, would be incurred in advance of any approval of a product candidate. In addition, we may not be able to hire a sales force in the United States that is sufficient in size or has adequate expertise in the medical markets that we intend to target. If we are unable to establish our sales force and marketing capability, our operating results may be adversely affected. In addition, in February 2021 we entered into an agreement with Amplity, Inc., for the potential upcoming commercial launch of ibrexafungerp for the treatment of VVC in the U.S., and will utilize Amplity’s 24 commercial execution expertise and resources for sales force, remote engagement, training, market access and select operation services. However, if Amplity does not perform under this agreement in the manner we expect, or Amplity were to terminate this agreement, this would significantly impair or delay our ability to commercialize ibrexafungerp for the treatment of VVC in the U.S. if approved. Further, 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. We plan to enter into additional sales and marketing or licensing arrangements with third parties for international sales of any approved products. If we are unable to enter into or maintain any such arrangements on acceptable terms, or at all, or these entities fail to perform as we intend under these agreements, we may be unable to market and sell ibrexafungerp or any future product candidates we may seek to develop in these markets. We expect that ibrexafungerp 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, ibrexafungerp 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 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: • • • • • • • • resources, including capital, personnel and technology; research and development capability; clinical trial expertise; regulatory expertise; intellectual property portfolios; expertise in prosecution of intellectual property rights; manufacturing and distribution expertise; and sales and marketing expertise. 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. 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. Because ibrexafungerp is not currently commercially available, we do not know the extent to which it will be able to obtain favorable coverage and adequate reimbursement from third-party payors if it is approved by the FDA. 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- 25 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. 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. Healthcare policy changes, including the Affordable Care Act, or changes or repeal of the Affordable Care Act, may have a material adverse effect on us. 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, President Trump signed several executive orders and other directives designed to delay the implementation of certain provisions of the Affordable Care Act or otherwise circumvent some of the requirements for health insurance mandated by the Affordable Care Act. Concurrently, Congress considered legislation to replace or repeal and replace all or part of the Affordable Care Act. While Congress has not passed comprehensive repeal legislation, several bills affecting the implementation of certain taxes under the Affordable Care Act have been signed into law. 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”. Additionally, the 2020 federal spending package permanently eliminated, effective January 1, 2020, the Affordable Care Act-mandated “Cadillac” tax on certain high cost employer-sponsored health coverage and medical device tax and, effective January 1, 2021, also eliminated the health insurer tax. Further, the Bipartisan Budget Act of 2018 (BBA) among other things, amended the Affordable Care Act, effective January 1, 2019, to increase from 50 percent to 70 percent the point-of-sale discount that is owed by pharmaceutical manufacturers who participate in Medicare Part D and to close the coverage gap in most Medicare drug plans, commonly referred to as the “donut hole”. On December 14, 2018, a Texas U.S. District Court Judge ruled that the Affordable Care Act is unconstitutional in its entirety because the “individual mandate” was repealed by Congress as part of the Tax Cuts and Jobs Act of 2017. On December 18, 2019, the U.S. Court of Appeals for the 5th Circuit ruled that the individual mandate was unconstitutional and remanded the case back to the District Court to determine whether the remaining provisions of the Affordable Care Act are invalid as well. The U.S. Supreme Court is currently reviewing the case, although it is unclear when a decision will be made or how the Supreme Court will rule. Although the Supreme Court has not yet ruled on the constitutionality of the Affordable Care Act, on January 28, 2021, President Biden issued an executive order to initiate a special enrollment period from February 15, 2021 through May 15, 2021 for purposes of obtaining health insurance coverage through the Affordable Care Act marketplace. The executive order also instructs certain governmental agencies to review and reconsider their existing policies and rules that limit access to healthcare, including among others, reexamining Medicaid demonstration projects and waiver programs that include work requirements, and policies that create unnecessary barriers to obtaining access to health insurance coverage through Medicaid or the Affordable Care Act. It is unclear how the Supreme Court ruling, other such litigation, and the healthcare reform measures of the Biden Administration will impact the Affordable Care Act and our business. 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 and proposed and 26 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, at the federal level, the Trump administration used several means to propose or implement drug pricing reform, including through federal budget proposals, executive orders and policy initiatives. For example, on July 24, 2020 and September 13, 2020, the Trump administration announced several executive orders related to prescription drug pricing that attempt to implement several of the administration’s proposals. The FDA also released a final rule, effective November 30, 2020, implementing a portion of the importation executive order providing guidance for states to build and submit importation plans for drugs from Canada. Further, on November 20, 2020, HHS finalized a regulation removing safe harbor protection for price reductions from pharmaceutical manufacturers to plan sponsors under Part D, either directly or through pharmacy benefit managers, unless the price reduction is required by law. The implementation of the rule has been delayed by the Biden administration from January 1, 2022 to January 1, 2023 in response to ongoing litigation. The rule also creates a new safe harbor for price reductions reflected at the point-of-sale, as well as a new safe harbor for certain fixed fee arrangements between pharmacy benefit managers and manufacturers, the implementation of which have also been delayed pending review by the Biden administration until March 22, 2021. On November 20, 2020, CMS issued an interim final rule implementing President Trump’s Most Favored Nation executive order, which would tie Medicare Part B payments for certain physician-administered drugs to the lowest price paid in other economically advanced countries, effective January 1, 2021. On December 28, 2020, the United States District Court in Northern California issued a nationwide preliminary injunction against implementation of the interim final rule. However, it is unclear whether the Biden administration will work to reverse these measures or pursue similar policy initiatives. 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. Further, it is possible that additional governmental action is taken in response to the COVID-19 pandemic. We expect that a portion of the market for ibrexafungerp 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 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: • • • ibrexafungerp and any future product candidates we may seek to develop may not generate preclinical or clinical data that are deemed sufficient by regulators in a given jurisdiction; ibrexafungerp may not be approved for all indications requested, or any indications at all, in a given jurisdiction which could limit the uses of ibrexafungerp and any future product candidates we may seek to develop and have an adverse effect on product sales and potential royalties; and such approval in a given jurisdiction may be subject to limitations on the indicated uses for which the product may be marketed or require costly post- marketing follow-up studies. 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. Even if ibrexafungerp or any other future product candidates we may seek to develop receive regulatory approval, we may still face future development and regulatory difficulties. Even if regulatory approval is obtained for 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 27 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. 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: • • • • • • • • • issue warning letters; mandate modifications to promotional materials or require us to provide corrective information to healthcare practitioners; require us or our partners to enter into a consent decree, which can include imposition of various fines, reimbursements for inspection costs, required due dates for specific actions and penalties for noncompliance; impose other civil or criminal penalties; suspend regulatory approval; suspend any ongoing clinical trials; refuse to approve pending applications or supplements to approved applications filed by us, our partners or our potential future partners; impose restrictions on operations, including costly new manufacturing requirements; or seize or detain products or require a product recall. 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 28 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 (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) and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family members. Beginning in 2022, applicable manufacturers also will be required to report such information regarding its payments and other transfers of value to physician assistants, nurse practitioners, clinical nurse specialists, anesthesiologist assistants, certified registered nurse anesthetists and certified nurse midwives during the previous year. 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. 29 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. Risks Related to Our Dependence on Third Parties We are dependent on our existing third-party collaboration with Amplity, Inc. to commercialize ibrexafungerp for the treatment of VVC in the U.S., and if Amplity is not successful in commercializing ibrexafungerp in the U.S., we may not be successful in commercializing ibrexafungerp in the U.S. In February 2021, we entered into an agreement with Amplity, Inc., for the potential upcoming commercial launch of ibrexafungerp for the treatment of VVC in the U.S., and will utilize Amplity’s commercial execution expertise and resources for sales force, remote engagement, training, market access and select operation services. However, if Amplity does not perform under this agreement in the manner we expect, or Amplity were to terminate this agreement, this would significantly impair or delay our ability to commercialize ibrexafungerp for the treatment of VVC in the U.S. if approved. 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 chaina, 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. 30 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. If ibrexafungerp is approved, the inability to manufacture sufficient commercial supplies of the drug product 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. 31 Reliance on third-party manufacturers entails risks to which we would not be subject if we manufactured product candidates ourselves, including: • • • the possible breach of the manufacturing agreements or violation of regulatory standards by the third parties because of factors beyond our control; the possibility of termination or nonrenewal of the agreements by the third parties because of our breach of the manufacturing agreement or based on their own business priorities; and the possibility of unforeseen natural disasters, public health crises, political crises and other catastrophic events or other events outside of our control impacting our third parties, such as the recent emergence and spread of COVID-19, a coronavirus, which may cause delays in the ability of our suppliers to provide us with supplies on a timely basis. 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. Risks Relating to Our Intellectual Property 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. 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: 32 • • • • • • others may be able to make compounds that are similar to ibrexafungerp and any future product candidates we may seek to develop but that are not covered by the claims of our patents; if we encounter delays in our clinical trials, the period of time during which we could market our drug candidates under patent protection would be reduced; we might not have been the first to conceive, make or disclose the inventions covered by our patents or pending patent applications; we might not have been the first to file patent applications for these inventions; any patents that we obtain may be invalid or unenforceable or otherwise may not provide us with any competitive advantages; or the patents of others may have a material adverse effect on our business. 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 33 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. Risks Related to Employee Matters and Managing Growth 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 34 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, 2021, we had 38 employees. If the FDA approves our NDA for ibrexafungerp for the treatment of VVC, as we expect to occur in June 2021, we will need to increase our marketing, sales and administrative headcount to manage the commercialization of ibrexafungerp for the treatment of VVC. Further, as we advance ibrexafungerp 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: • • • • successfully attract and recruit new employees with the expertise and experience we will require; manage our clinical programs effectively, which we anticipate being conducted at numerous clinical sites; develop a marketing and sales infrastructure; and continue to develop our operational, financial and management controls, reporting systems and procedures. If we are unable to successfully manage this growth, our business may be adversely affected. Other Risks Relating to Our Business We 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: • • • • • • • • withdrawal of clinical trial participants; termination of clinical trial sites or entire trial programs; costs of related litigation; substantial monetary awards to patients or other claimants; decreased demand for product candidates and loss of revenue; impairment of our business reputation; diversion of management and scientific resources from our business operations; and the inability to commercialize product candidates. We have obtained limited product liability insurance coverage for our clinical trials domestically and in selected foreign countries where we are conducting clinical trials. Our coverage is currently limited to $10.0 million per occurrence and $10.0 million in the aggregate per year, as well as additional local country product liability coverage for trials conducted outside of the United States as required by the local country regulations. 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. 35 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. U.S. and foreign privacy and data protection laws and regulations may impose additional liabilities on us. U.S. federal and state privacy and data security laws and regulations regulate how we and our partners collect, use and share certain information. 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. State security breach notification laws, state health information privacy laws, and other state privacy laws also impose requirements regarding the collection, use, disclosure, and protection of personal information. In addition, in June 2018, California enacted the California Consumer Privacy Act of 2018 (CCPA) which became effective January 1, 2020. The CCPA gives California residents the right to access and require deletion of their personal information, the right to opt out of certain personal information sharing, and the right to detailed information about how their personal information is collected, used, and disclosed. The CCPA provides for civil penalties for violations, as well as a private right of action for data breaches that is expected to increase data breach litigation. Although the CCPA includes exemptions for certain clinical trials data and data collected pursuant to HIPAA, the law may increase our compliance costs and potential liability with respect to other personal information we collect about California residents. The CCPA has prompted a wave of proposals for new federal and state privacy legislation that, if passed, could increase our potential liability, increase our compliance costs, and adversely affect our business. We may also be subject to or affected by foreign laws and regulations, including regulatory guidance, governing the collection, use, disclosure, security, transfer, and storage of personal data, such as information that we collect about patients in connection with clinical trials and our other operations abroad. The global legislative and regulatory landscape for privacy and data protection continues to evolve, and implementation standards and enforcement practices are likely to remain uncertain for the foreseeable future. This evolution may create uncertainty in our business, result in liability, or impose additional costs on us. The cost of compliance with these laws, regulations and standards is high and is likely to increase in the future. For example, the EU implemented the General Data Protection Regulation (GDPR) a broad data protection framework that expands the scope of EU data protection law to include certain non-European Union entities that process the personal data of EU residents, including clinical trial data. The GDPR increases our compliance burden with respect to data protection, including by mandating potentially burdensome documentation requirements and granting certain rights to individuals to control how we collect, use, disclose, retain and protect information about them. The processing of sensitive personal data, such as information about health conditions, leads to heightened compliance burdens under the GDPR and is a topic of active 36 interest among EU regulators. In addition, the GDPR provides for breach reporting requirements, more robust regulatory enforcement and fines of up to the greater of 20 million euros or 4% of annual global revenue. The GDPR increases our responsibility and liability in relation to personal data that we process, including in clinical trials, and we may be required to put in place additional mechanisms to ensure compliance with the GDPR, which could divert management’s attention and increase our cost of doing business. A data security breach or other privacy violation that compromises the confidentiality, integrity or availability of the personal information of our clinical trials participants, collaborators or employees could harm our reputation, compel us to comply with U.S. or international breach notification laws, subject us to mandatory corrective action, and otherwise subject us to liability under U.S. or foreign laws and regulations. Data breaches or other security incidents could also compromise our trade secrets or other intellectual property. If we are unable to prevent such data security breaches and security incidents or implement satisfactory remedial measures, our operations could be disrupted, and we may suffer reputational harm, financial loss or other regulatory penalties. In addition, such events can be difficult to detect, and any delay in identifying them may lead to increased harm. While we have implemented security measures designed to protect our information technology systems, such measures may not prevent such events. Finally, it is possible that these privacy laws may be interpreted and applied in a manner that is inconsistent with our practices. Any failure or perceived failure by us to comply with federal, state, or foreign laws or self-regulatory standards could result in negative publicity, diversion of management time and effort, and proceedings against us by governmental entities or others. If we expand into other foreign countries and jurisdictions, we may be subject to additional privacy and data protection laws and regulations that may affect how we conduct business. The market price of our common stock may be highly volatile. Risks Relating to Owning Our Common Stock 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: • • • • • • • • • • • • • • • • • • whether or not our NDA for ibrexafungerp for the treatment of VVC is approved, denied or delayed by the FDA; the results of our preclinical testing or clinical trials; the ability to obtain additional funding; any delay in submitting an NDA or similar foreign applications for ibrexafungerp and any future product candidate we may seek to develop or any adverse development or perceived adverse development with respect to the FDA’s review of that NDA or a foreign regulator’s review of a similar applications; maintenance of our existing collaborations or ability to enter into new collaborations; our collaboration partners’ election to develop or commercialize product candidates under our collaboration agreements or the termination of any programs under our collaboration agreements; any intellectual property infringement actions in which we or our licensors and collaboration partners may become involved; our ability to successfully develop and commercialize future product candidates; changes in laws or regulations applicable to future products; adverse regulatory decisions; introduction of new products, services or technologies by our competitors; achievement of financial projections we may provide to the public; achievement of the estimates and projections of the investment community; the perception of the pharmaceutical industry by the public, legislatures, regulators and the investment community; changes in the structure of healthcare payment systems; announcements of significant acquisitions, strategic partnerships, joint ventures or capital commitments by us, our collaboration partners or our competitors; disputes or other developments relating to proprietary rights, including patents, litigation matters and our ability to obtain patent protection for our technologies; legislation or regulation that mandates or encourages the use of generic products; 37 • • • • • • additions or departures of key scientific or management personnel; significant lawsuits, including patent or stockholder litigation; changes in the market valuations of similar companies; general economic and market conditions and overall fluctuations in the U.S. equity markets; sales of our common stock by us, our executive officers and directors or our stockholders in the future; and trading volume 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 and April 2020, we issued and sold $16 million and $10 million, respectively, 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 (for the notes issued in March 2019) and April 15, 2026 (for the notes issued in April 2020). 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. 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. Sales of our common stock to Aspire Capital may cause substantial dilution to our existing stockholders and the sale of the shares of our common stock acquired by Aspire Capital could cause the price of our common stock to decline. We may issue and sell to Aspire Capital from time to time pursuant to the common stock purchase agreement an aggregate amount of up to $20.0 million of shares of common stock. It is anticipated that shares offered to Aspire Capital will be sold over a period of up to 30 months from April 2020. The number of shares ultimately offered for sale to Aspire Capital is dependent upon the number of shares we elect to sell to Aspire Capital under the common stock purchase agreement. Depending upon market liquidity at the time, sales of shares of our common stock under the common stock purchase agreement may cause the trading price of our common stock to decline. Aspire Capital may ultimately purchase all, some or none of the shares of common stock that, together with the 70,910 commitment shares. After Aspire Capital has acquired shares under the common stock purchase agreement, it may sell all, some or none of those shares. Sales to Aspire Capital by us pursuant to the common stock purchase agreement may result in substantial dilution to the interests of other holders of our common stock. The sale of a substantial number of shares of our 38 common stock to Aspire Capital in this offering, or anticipation of such sales, could make it more difficult for us to sell equity or equity-related securities in the future at a time and at a price that we might otherwise wish to effect sales. However, we have the right to control the timing and amount of any sales of our shares to Aspire Capital and the common stock purchase agreement may be terminated by us at any time at our discretion without any cost to us. We have a right to sell up to 25,000 purchase shares per day under our common stock purchase agreement with Aspire Capital, which total may be increased by mutual agreement up to an additional 200,000 purchase shares per day. The extent to which we rely on Aspire Capital as a source of funding will depend on a number of factors, including the prevailing market price of our common stock and the extent to which we are able to secure working capital from other sources. The aggregate number of shares that we can sell to Aspire Capital under the common stock purchase agreement may in no case exceed 1,956,547 shares of our common stock (which is equal to approximately 19.99% of the common stock outstanding on the date of the common stock purchase agreement), including the 70,910 commitment shares (the Exchange Cap), unless either (a) shareholder approval is obtained to issue more, in which case the Exchange Cap will not apply, or (b) the average purchase price of all shares sold under the common stock purchase agreement exceeds $8.461; provided that at no time shall Aspire Capital (together with its affiliates) beneficially own more than 19.99% of our common stock. Our business could be adversely affected by the COVID-19 outbreak, in regions where we or third parties on which we rely have significant concentrations of clinical trial sites, manufacturing facilities, or other business operations. Our business could be adversely affected by the COVID-19 outbreak, 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 the COVID-19 health epidemic 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. ITEM 1B. UNRESOLVED STAFF COMMENTS None. ITEM 2. PROPERTIES 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.

Overview SCYNEXIS, Inc. is pioneering innovative medicines to potentially help millions of patients worldwide in need of new options to overcome and prevent difficult-to-treat and drug-resistant infections. We are developing our lead product candidate, ibrexafungerp, as a broad-spectrum, intravenous (IV)/oral agent for multiple fungal indications in both the community and hospital settings. In December 2020, we announced that we had received the acceptance letter from the U.S. Food and Drug Administration (FDA) for our New Drug Application (NDA) for oral ibrexafungerp for the treatment of vulvovaginal candidiasis (VVC, also known as vaginal yeast infection) with a Prescription Drug User Fee Act (PDUFA) action goal date of June 1, 2021. The FDA has conditionally approved “Brexafemme” as the brand name for oral ibrexafungerp for vaginal yeast infections. We are also continuing late-stage clinical development for the prevention of recurrent VVC as well as the treatment of life-threatening invasive fungal infections in hospitalized patients. Ibrexafungerp, the first representative of a novel class of antifungal agents called triterpenoids and designated by the suffix “-fungerp”, is a structurally distinct glucan synthase inhibitor and has shown in vitro and in vivo activity against a broad range of human fungal pathogens such as Candida and Aspergillus species, including multidrug- resistant strains, as well as Pneumocystis, Coccidioides, Histoplasma and Blastomyces species. Candida and Aspergillus species are the fungi responsible for approximately 85% of all invasive fungal infections in the United States (U.S.) and Europe. To date, we have characterized the antifungal activity, pharmacokinetics, and safety profile of the oral and IV formulations of ibrexafungerp in multiple in vitro, in vivo, and clinical studies. The FDA has granted Qualified Infectious Disease Product (QIDP) and Fast Track designations to ibrexafungerp for the indications of VVC (including the treatment of VVC episodes and 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. These designations may provide us with additional market exclusivity and expedited regulatory paths. Ibrexafungerp Update We recently announced that the FDA has accepted for filing our NDA for ibrexafungerp for the treatment of VVC, also known as vaginal yeast infections. The FDA has granted this application Priority Review, a designation which is granted to applications for potential drugs that, if approved, would be significant improvements in the safety or effectiveness of the treatment of serious conditions when compared to standard applications. Under the PDUFA, the FDA has set a target action date of June 1, 2021. Additionally, the FDA has communicated that it is not currently planning to hold an advisory committee meeting to discuss the application. The NDA is supported by positive results from two Phase 3, randomized, double-blind, placebo-controlled, multi-center studies (VANISH-303 and VANISH-306), in which oral ibrexafungerp demonstrated statistically superior efficacy and a favorable tolerability profile in women with VVC. Enrollment is complete in the CANDLE study, a Phase 3, multi-center, randomized, double-blind, placebo-controlled trial designed to evaluate the efficacy and safety of oral ibrexafungerp for the prevention of recurrent VVC, for which there is no approved therapy in the U.S. As a result of the COVID-19 pandemic, our timelines for reaching our targeted enrollment size in the CANDLE study were slightly extended and we now anticipate both top-line data and a potential supplemental NDA submission for the prevention of recurrent VVC in the first half of 2022, resulting in a potential approval in late 2022. Enrollment is ongoing in our refractory invasive fungal infections (rIFI) program, which comprises two open-label Phase 3 studies (FURI and CARES) designed to support a potential future NDA submission through the Limited Population Pathway for Antibacterial and Antifungal Drugs (LPAD), as well as our Phase 2 study (SCYNERGIA study) of oral ibrexafungerp in combination with voriconazole (SoC) in patients with IA. Similar to interim analyses of data previously reported, we intend to analyze the data of patients that have completed the treatment course in our FURI and CARES studies and announce these findings when complete. 41 We have successfully completed preclinical testing of our liposomal IV formulation of ibrexafungerp and we are advancing the program into human trials in healthy volunteers. The first trial is being conducted as a Phase 1, randomized, double-blind, placebo-controlled study to evaluate the safety, tolerability, and pharmacokinetics of the IV liposomal formulation of ibrexafungerp in healthy subjects. The study is being conducted in South Africa and dosing started in March 2021. Corporate Update On December 2, 2020, we amended our license agreement with Merck Sharp & Dohme Corp. (Merck), dated May 24, 2013. 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., anticipated in June 2021 for our 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, we 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. On December 17, 2020, we completed a public offering (the December 2020 Public Offering) of our common stock and warrants pursuant to our effective shelf registration. We sold an aggregate of (a) 8,340,000 shares of our common stock, par value $0.001 per share, (b) pre-funded warrants, in lieu of common stock, to purchase 5,260,000 shares of our common stock, par value $0.001 per share, and (c) two series of warrants, which will accompany the common stock or pre-funded warrants, to purchase up to an aggregate of 13,600,000 shares of our common stock and received approximately $79.5 million in net proceeds. In February 2021, we partnered with Amplity Inc. (Amplity) for the potential upcoming commercial launch of ibrexafungerp for the treatment of VVC. Under the terms of the 5-year agreement, we will utilize Amplity’s commercial execution expertise and resources for sales force, remote engagement, training, market access and select operations services. We will maintain full ownership of ibrexafungerp and control of all strategic aspects of the launch. Amplity is deferring a portion of its direct service costs in the first two years (2021 and 2022), which we will repay over three years starting in 2023. Amplity has the potential to earn a performance-based success fee in the 2023- 2025 time frame by exceeding certain revenue targets. On February 11, 2021, we entered into an Exclusive License and Collaboration Agreement (the Agreement) with Hansoh (Shanghai) Health Technology Co., Ltd., and Jiangsu Hansoh Pharmaceutical Group Company Limited (collectively, Hansoh), pursuant to which Hansoh obtains an exclusive license from us to research, develop and commercialize ibrexafungerp in the Greater China region, including mainland China, Hong Kong, Macau, and Taiwan. Under the terms of the 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 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. Impact of COVID-19 Pandemic on Our Business A novel strain of coronavirus (COVID-19) was first identified in December 2019, and subsequently declared a global pandemic by the World Health Organization on March 11, 2020. The full extent of the future impacts of COVID-19 on our operations is uncertain and a prolonged outbreak could have an adverse effect on our business. We continue to see enrollment across our ongoing studies but have observed that the pandemic has resulted in some delays to some of our clinical studies, particularly in our CANDLE study, with top-line data now expected in the first half of 2022, as the initiation of new investigational sites can be delayed due to the diversion of their resources away from necessary start-up activities, and by limiting the ability of investigational sites to conduct all activities associated with our ongoing studies. For example, the circumstances can hinder the investigational sites’ ability to screen patients for enrollment. We are collaborating with our investigational sites to implement measures to minimize disruptions to patients and ensure continued access to treatment, in accordance with health authority guidance. With respect to manufacturing and supply, we currently have sufficient drug supply for our ongoing clinical studies. Our third-party contract manufacturers continue to operate at or near normal levels and, at this time and subject to further COVID-19 implications, we do not anticipate any disruptions to our drug supply chain. Additionally, our employees have been transitioned to a work-from-home policy and this has not had any material impact on our internal operating abilities. The extent of the impact of COVID-19 on our business, financial results, liquidity and cash flows will depend largely on future developments. Any potential delays in clinical studies as a result of the impact of COVID-19, particularly on our CANDLE study, could result in the recognition of research and development expense for these studies in periods later than 42 originally anticipated and could potentially further extend our cash runway. As of December 31, 2020, we had $93.0 million in cash and cash equivalents, and we may utilize our common stock purchase agreement entered into on April 10, 2020 with Aspire Capital Fund, LLC (Aspire Capital) in order to provide additional liquidity. Our ability to acquire necessary capital may be negatively impacted by the economic environment if the pandemic is prolonged. The ultimate impact of the COVID-19 health pandemic is highly uncertain and subject to change. We do not yet know the full extent of potential impacts on our business, our clinical trials, our activities dependent on regulatory authorities, healthcare systems or the global economy as a whole. We will continue to monitor the COVID-19 situation closely. Liquidity 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, and December 2020. We have received an aggregate of $253.2 million in net proceeds from the issuance of our common stock in these six offerings. Our principal source of liquidity is cash and cash equivalents, which totaled $93.0 million as of December 31, 2020. In addition, during the year ended December 31, 2020, we sold 691,304 shares of our common stock and received net proceeds of $4.8 million under our at-the-market (ATM) facility, sold 125,000 shares of our common stock and received net proceeds of $0.6 million under our common stock purchase agreement with Aspire Capital, and in April 2020, we received a cash receipt of $3.1 million from a third party for the sale of a portion of our unused New Jersey Net Operating Losses (NOLs) and research and development credits. We have incurred net losses since our inception, including the year ended December 31, 2020. As of December 31, 2020, our accumulated deficit was $326.6 million. We expect we will continue to incur significant research and development expense as we continue to execute our research and drug development strategy, but that our research and development expenses will decrease primarily given the completion of the VANISH Phase 3 registration program. Consistent with our operating plan, we also expect that we will continue to incur significant selling, general and administrative expenses to support our public reporting company operations, and that our selling, general and administrative expenses will increase to support a potential commercial launch for the VVC indication and our 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, and New Jersey Technology Business Tax Certificate Transfer (NOL) Program), strategic alliances and licensing or collaboration arrangements. We may offer shares of our common stock pursuant to our effective shelf registrations and the common stock purchase agreement with Aspire Capital. Components of Operating Results Revenue Revenue consists of the amortization of a non-refundable upfront payment received under our collaboration arrangement with R-Pharm. Research and Development Expense 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: • costs related to executing preclinical studies and clinical trials, including related drug formulation, manufacturing and other development; • salaries and personnel-related costs, including benefits and any stock-based compensation for personnel performing research and development functions; • fees paid to clinical research organizations (CROs), vendors, consultants and other third parties who support our product candidate development and intellectual property protection; • other costs in seeking regulatory approval of our products; and • allocated overhead. Ibrexafungerp was the only key research and development project 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 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. 43 Selling, General and Administrative Expense 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. Other Expense (Income) Substantially all of our other expense (income) during the periods reported consists of costs associated with: • fair value adjustments to our warrant and derivative liabilities; • interest expense; • amortization of debt issuance costs and discount; • other income associated with research and development tax credits; • interest income associated with our held-to-maturity short-term investments • other expense and; • the expense recognized for the extinguishment of debt. Income Tax Benefit Income tax benefit consists of U.S. federal and state income taxes. 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 year ended December 31, 2020, we recognized $3.1 million in income tax benefit associated with the sale of our NOLs and research and development credits. Results of Operations for the Years Ended December 31, 2020 and 2019 The following table summarizes our results of operations for the years ended December 31, 2020 and 2019, and period-to-period percentage change (dollars in thousands): Revenue Operating expenses: Research and development Selling, general and administrative Total operating expenses Loss from operations Other expense (income): Loss on extinguishment of debt Amortization of debt issuance costs and discount Interest income Interest expense Other income Other expense Warrant liabilities fair value adjustment Derivative liabilities fair value adjustment Total other expense: Loss before taxes Income tax benefit Net Loss 2020 Years Ended December 31, 2019 Period-to-Period Change $ — $ 121 $ (121 ) (100.0 )% 36,522 14,627 51,149 (51,149 ) 1,766 1,201 (189 ) 1,181 (334 ) 602 5,214 (2,257 ) 7,184 (58,333 ) 3,148 (55,185 ) $ $ 38,394 10,648 49,042 (48,921 ) 1,045 1,171 (805 ) 986 (538 ) — 4,497 (1,567 ) 4,789 (53,710 ) — (53,710 ) $ (1,872 ) 3,979 2,107 (2,228 ) 721 30 616 195 204 602 717 (690 ) 2,395 (4,623 ) 3,148 (1,475 ) (4.9 )% 37.4 % 4.3 % 4.6 % 69.0 % 2.6 % (76.5 )% 19.8 % (37.9 )% — 15.9 % 44.0 % 50.0 % 8.6 % — 2.7 % Revenue. For the year ended December 31, 2019, revenue consisted of the amortization of a non-refundable upfront payment received under our collaboration arrangement with R-Pharm and was fully amortized in 2019. Research and Development. For the year ended December 31, 2020, research and development expenses decreased to $36.5 million from $38.4 million for the year ended December 31, 2019. The decrease of $1.9 million, or 4.9%, was primarily driven by a milestone payment made in 2019 to Merck upon initiation of the Phase 3 VVC registration study, a decrease of $4.2 million in clinical development expense, a decrease of $1.0 million in preclinical expense, offset in part by an increase of 44 $4.5 million in chemistry, manufacturing, and controls (CMC), an increase of $1.1 million in salary and consulting related expense, an increase of $1.1 million in regulatory expense, and a net increase in other research and development expense of $0.6 million. The $4.2 million decrease in clinical development expense for the year ended December 31, 2020, was primarily driven by a decrease of $9.2 million in costs associated with the VANISH Phase 3 VVC program that was substantially complete by the beginning of the third quarter of 2020, a decrease of $0.8 million in expense associated with the SCYNERGIA study, a decrease of $0.4 million in expense associated with two drug-drug interaction clinical studies to support the NDA submission for the treatment of VVC indication, offset in part by an increase of $4.6 million in costs associated with the CANDLE Phase 3 study, an increase of $0.5 million in expense associated with certain Phase 1 studies to support the NDA submission for the treatment of VVC indication, a $0.6 million increase in expense associated with the FURI and CARES studies, and a net increase in other clinical expenses of $0.5 million. The $4.5 million increase in CMC for the year ended December 31, 2020, was primarily driven by increased costs associated with the development and manufacture of drug product for ongoing and planned clinical studies as well as commercial batches necessary for a potential commercial launch of ibrexafungerp in the second half of 2021. The $1.1 million increase in salary and consulting related expense is primarily due to the increase in full time employees from the comparable prior period. The $1.1 million increase in regulatory expense was primarily due to the additional costs incurred during the period for the preparation and filing of the NDA submission for the treatment of VVC. Selling, General and Administrative. For the year ended December 31, 2020, selling, general and administrative expenses increased to $14.6 million from $10.6 million for the year ended December 31, 2019. The increase of $4.0 million, or 37.4%, was primarily driven by a $1.5 million increase in commercial and business development expense, a $1.3 million increase in other professional service expense, a $0.9 million increase in salary and other compensation related costs, and a net increase in other selling, general and administrative expenses of $0.3 million. The $1.5 million increase in commercial and business development expense is primarily due to the costs incurred in preparation of the potential commercial launch of ibrexafungerp for the treatment of VVC in the second half of 2021. Loss on Extinguishment of Debt. For the year ended December 31, 2020, we recognized a $1.8 million loss on extinguishment of debt associated with the conversion of a portion of our April 2020 6.0% Convertible Senior Notes (April 2020 Notes) and, with respect to the 2019 period, a $0.8 million loss on extinguishment of debt associated with the repayment of the term loan with Solar and a $0.2 million loss on debt extinguishment upon the conversion of a portion of our March 2019 6.0% Convertible Senior Notes (March 2019 Notes). Amortization of Debt Issuance Costs and Discount. For the years ended December 31, 2020 and 2019, amortization of debt issuance costs and discount was $1.2 million. The 2020 and 2019 debt issuance costs and discount comprised an allocated portion of the advisory fee and other issuance costs associated with our convertible debt and the fair value of the bifurcated derivative liability. Interest Income. For the years ended December 31, 2020 and 2019, we recognized $0.2 million and $0.8 million, respectively, in interest income associated with our short-term investments. The decrease in interest income was primarily due to the decrease in interest rate returns earned in comparison to the comparable period and the maturity of all our short-term investments during the current period. Interest Expense. For the years ended December 31, 2020 and 2019, we recognized $1.2 million and $1.0 million, respectively, in interest expense associated with our convertible debt. The increase from the prior comparable period is primarily due to the additional interest expense recognized for the April 2020 Notes. Other Income. For the years ended December 31, 2020 and 2019, we recognized $0.3 million and $0.5 million in other income associated with certain research and development tax credits. Other Expense. For the year ended December 31, 2020, we recognized $0.6 million in expense associated with the noncash consideration associated with the common stock purchase agreement entered into with Aspire Capital in April 2020. Warrant Liabilities Fair Value Adjustment. For the years ended December 31, 2020 and 2019, we recognized losses of $5.2 million and $4.5 million, respectively, for the fair value adjustment for warrant liabilities primarily due to the increase in our stock price during the periods. Derivative Liabilities Fair Value Adjustment. For the years ended December 31, 2020 and 2019, we recognized gains of $2.3 million and $1.6 million, respectively, in the fair value adjustment related to the derivative liabilities primarily due to the decrease in our stock price during the period. Income Tax Benefit. For the year ended December 31, 2020, we recognized a $3.1 million income tax benefit associated with the sale of a portion of our NOLs and research and development credits. This sale was structured through the New Jersey Technology Business Tax Certificate Transfer (NOL) Program. 45 Liquidity and Capital Resources Sources of Liquidity As of December 31, 2020, we had cash and cash equivalents of approximately $93.0 million, compared to cash, cash equivalents, and short-term investments of $48.4 million as of December 31, 2019. The increase in our cash and cash equivalents was primarily due to the funds raised in our December 2020 Public Offering of our common stock and warrants and through our ATM and Aspire facilities, the sale of our April 2020 Notes, the cash receipt of $3.1 million received in 2020 for the sale of a portion of our New Jersey NOLs, offset in part by the continued development costs associated with our lead product candidate, ibrexafungerp. We have incurred net losses since our inception, including the year ended December 31, 2020. As of December 31, 2020, our accumulated deficit was $326.6 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, New Jersey Technology Business Tax Certificate Transfer (NOL) Program), strategic alliances and licensing or collaboration arrangements. We may offer shares of our common stock pursuant to our Form S-3 shelf registration statements. For the year ended December 31, 2020, we received net proceeds of $4.8 million, under our ATM facility. In April 2020 and March 2019, we sold to Puissance Life Science Opportunities Fund VI (Puissance) $10.0 million and $16.0 million aggregate principal amount of our convertible senior notes (Notes), respectively. See Note 7 to our consolidated financial statements for the year ended December 31, 2020, included in this Annual Report for further details. Cash Flows The following table sets forth the significant sources and uses of cash for the years ended December 31, 2020 and 2019 (dollars in thousands): Cash, cash equivalents, and restricted cash, January 1 Net cash used in operating activities Net cash provided by investing activities Net cash provided by financing activities Net increase in cash, cash equivalents, and restricted cash Cash, cash equivalents, and restricted cash, December 31 Operating Activities Years Ended December 31, 2020 2019 $ $ 42,193 $ (49,354 ) 6,474 94,001 51,121 93,314 $ 11,767 (38,119 ) 26,240 42,305 30,426 42,193 The $11.2 million increase in net cash used in operating activities for the year ended December 31, 2020, as compared to the year ended December 31, 2019, was primarily due to increases in costs associated with ibrexafungerp development efforts. Consistent with our operating plan, we expect that our research and development expenses will decrease primarily given the completion of the VANISH Phase 3 registration program and we expect our selling, general and administrative expenses to increase to support a potential commercial launch for the treatment of VVC and our ongoing operations. Net cash used in operating activities of $49.4 million for the year ended December 31, 2020, primarily consisted of the $55.2 million net loss adjusted for non-cash charges that included the loss on change in fair value of the warrant liabilities of $5.2 million and stock-based compensation expense of $2.2 million, the gain on change in fair value of the derivative liabilities of $2.3 million, the loss on extinguishment of debt of $1.8 million, and the amortization of debt issuance costs and discount of $1.2 million, plus a net unfavorable change in operating assets and liabilities of $3.2 million. The net unfavorable change in operating assets and liabilities included a decrease in accounts payable and accrued expenses of $2.3 million and an increase in prepaid expenses, other assets, and deferred costs of $0.9 million. The $2.3 million decrease in accounts payable and accrued expenses was primarily due to the decrease in accounts payable of $2.5 million as of December 31, 2020. The $0.9 million increase in prepaid expenses, other assets, and deferred costs is primarily due to a $2.9 million increase for a receivable that was fully collected in February 2021, offset in part by a $1.2 million decrease in prepaid research and development costs associated with drug product shipped during the period. Net cash used in operating activities of $38.1 million for the year ended December 31, 2019, primarily consisted of the $53.7 million net loss adjusted for non-cash charges that included the loss on change in fair value of the warrant liabilities of $4.5 million and stock-based compensation expense of $1.8 million, the gain on change in fair value of the derivative liability of $1.6 million, the loss on extinguishment of debt of $1.0 million, and the amortization of debt issuance costs and discount of $1.2 million, plus a net favorable change in operating assets and liabilities of $8.3 million. The net favorable change in operating assets and liabilities included an increase in accounts payable and accrued expenses of $5.2 million primarily due to the increase in accounts payable and a decrease in prepaid expenses, other assets, and deferred costs of $3.3 46 million. The $3.3 million decrease in prepaid expenses, other assets, and deferred costs is primarily due the cash receipt of $6.7 million received in 2019 for the sale of a portion of our NOLs through the New Jersey Technology Business Tax Certificate Transfer (NOL) Program. Investing Activities Net cash provided by investing activities of $6.5 million for the year ended December 31, 2020, consisted primarily of purchases and maturities of short-term investments of $14.2 million and $20.7 million, respectively. Net cash provided by investing activities of $26.2 million for the year ended December 31, 2019, consisted of purchases and maturities of short-term investments of $39.5 million and $65.7 million, respectively. Financing Activities Net cash provided by financing activities of $94.0 million for the year ended December 31, 2020, consisted primarily of gross proceeds from common stock of $90.6 million, primarily as a result of our December 2020 public offering of common stock and warrants in addition to the gross proceeds from common stock sold under our ATM and Aspire facilities, partially offset by related underwriting discounts and commissions and offering expenses totaling $5.9 million. Additionally, pursuant to the April 2020 Notes, we issued and sold to Puissance $10.0 million aggregate principal amount of our April 2020 Notes, resulting in $9.5 million in net proceeds after deducting an advisory fee and other issuance costs. Net cash provided by financing activities of $42.3 million for the year ended December 31, 2019, consisted primarily of gross proceeds from common stock of $46.3 million, primarily as a result of our December 2019 public offering of common stock and warrants in additional to the gross proceeds from common stock sold under our ATM facilities, partially offset by related underwriting discounts and commissions and offering expenses totaling $2.9 million. Additionally, pursuant to the note purchase agreement, we issued and sold to Puissance $16.0 million aggregate principal amount of our March 2019 Notes, resulting in $14.7 million in net proceeds after deducting an advisory fee and other issuance costs, and we used the net proceeds to pay the remaining outstanding Solar term loan in full. As part of the payment of the outstanding balance of the Solar term loan, we paid $0.8 million in debt extinguishment costs which comprised the remaining unamortized discount and issuance costs associated with the Solar term loan prior to repayment. Future Funding Requirements To date, we have not generated any revenue from product sales. We do not know when, or if, we will generate any revenue from product sales. We do not expect to generate significant revenue from product sales unless and until we obtain regulatory approval of and commercialize ibrexafungerp. In addition, we expect to incur expenses in connection with our ongoing development activities, particularly as we continue the research, development and clinical trials of, and seek regulatory approval for, our product candidates. We anticipate that we will need substantial additional funding in connection with our continuing future operations. Based upon our existing operating plan, we believe that our existing cash and cash equivalents, the sale of a portion of our New Jersey NOLs, the upfront payment from Hansoh, and anticipated sales of Brexafemme will enable us to fund our operating requirements into 2023. These funds will also be sufficient to enable us to commercially launch Brexafemme for the treatment of vaginal yeast infections, if approved, and complete the development activities for the CANDLE study. However, 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. Our future capital requirements will depend on many factors, including: • the progress, costs, and the clinical research and development of ibrexafungerp; • the outcome, costs and timing of seeking and obtaining FDA and any other regulatory approvals; • the ability of our product candidates to progress through clinical development successfully; • our need to expand our research and development activities; • the costs associated with securing, establishing and maintaining commercialization and manufacturing capabilities; • our ability to maintain, expand and defend the scope of our intellectual property portfolio, including the amount and timing of any payments we may be required to make, or that we may receive, in connection with the licensing, filing, prosecution, defense and enforcement of any patents or other intellectual property rights; • our need and ability to hire additional management and scientific and medical personnel; 47 • our need to implement additional, as well as to enhance existing, internal systems and infrastructure, including financial and reporting processes and systems; and • the economic and other terms, timing and success of our existing licensing arrangements and any collaboration, licensing or other arrangements into which we may enter in the future. 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, New Jersey Technology Business Tax Certificate Transfer (NOL) Program), 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 previous loan agreement with Solar 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. Off-Balance Sheet Arrangements During the periods presented we did not have, nor do we currently have, any off-balance sheet arrangements as defined under SEC rules. Critical Accounting Policies and Significant Judgments and Estimates 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, 2020, 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. Research and Development Accruals 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. 48 Stock-Based Compensation 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): Research and development, net Selling, general and administrative Total Years Ended December 31, 2020 2019 $ $ 806 $ 1,414 2,220 $ 604 1,224 1,828 On December 31, 2020, the aggregate intrinsic value of outstanding options to purchase shares of our common stock was $0.1 million, based upon the $7.65 closing sales price per share of our common stock as reported on the Nasdaq Global Market on that date. Determination of the Fair Value of Stock-based Compensation Grants 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: • we estimate expected volatility based on the volatility of our own common stock trading history; • the assumed dividend yield is based on our expectation of not paying dividends on our underlying common stock for the foreseeable future; • we determine the average expected life of stock options based on the simplified method in accordance with SEC Staff Accounting Bulletin Nos. 107 and 110, as our common stock has a limited trading history. We expect to use the simplified method until we have sufficient historical exercise data to provide a reasonable basis upon which to estimate expected term; • we determine the risk-free interest rate by reference to implied yields available from U.S. Treasury securities with a remaining term equal to the expected life assumed at the date of grant; and • we recognize forfeitures as they are incurred. The assumptions used in the Black-Scholes option-pricing model for the years ended December 31, 2020 and 2019 are set forth below: Employee Stock Options Weighted average risk-free interest rate Weighted average expected term (in years) Weighted average expected volatility Non-Employee Director Stock Options Weighted average risk-free interest rate Weighted average expected term (in years) Weighted average expected volatility Warrant Liabilities Years Ended December 31, 2020 2019 1.18 % 5.97 64.67 % Years Ended December 31, 2020 2019 0.36 % 5.50 66.55 % 2.47 % 6.03 66.47 % 2.11 % 5.54 65.36 % We account for the outstanding warrants associated with the June 2016, March 2018, December 2019, and December 2020 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. See Note 2 to our consolidated financial statements on this Annual Report for further details. 49 Convertible Debt and Derivative Liabilities For the convertible notes, we account for the bifurcated embedded conversion option, inclusive of the interest make-whole provision and make-whole fundamental change provision, as long-term derivative liabilities in our consolidated balance sheet. The derivative liabilities are 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 liabilities at inception and on subsequent valuation dates. This model incorporates transaction details such as stock price, contractual terms, dividend yield, risk- free rate, historical volatility, credit rating, market credit spread, and estimated yield. See Note 2 to our consolidated financial statements on this Annual Report for further details. ITEM 7A.

Opinion on the Financial Statements We have audited the accompanying consolidated balance sheets of SCYNEXIS, Inc. and subsidiaries (the "Company") as of December 31, 2020 and 2019, 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, 2020, 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, 2020 and 2019, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2020, in conformity with accounting principles generally accepted in the United States of America. Basis for Opinion 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. Critical Audit Matter 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. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates. Convertible Debt and Derivative Liabilities – April 2020 Note Purchase Agreement – Refer to “Note 2 – Summary of Significant Accounting Policies” and “Note 7 – Borrowings” to the financial statements Critical Audit Matter Description In April 2020, the Company entered into a Senior Convertible Note Purchase Agreement pursuant to which it issued and sold $10.0 million aggregate principal amount of 6.0% Convertible Senior Notes (the “April 2020 Notes”), each of which are convertible into shares of the Company’s common stock. Upon issuance of the April 2020 Notes, the Company bifurcated the fair value of the embedded conversion option from the April 2020 Notes and recorded it as a derivative liability in accordance with ASC 815, Derivatives and Hedging. Both the April 2020 Notes and the derivative liability have been classified as long-term and presented as “Convertible debt and derivative liabilities” in the Company’s consolidated balance sheet. Prospectively, the convertible debt is required to be carried at amortized cost, while the derivative liability component is remeasured at each reporting period with changes in fair value recorded in the Company’s consolidated statements of operations as other (income) expense. The calculation of the fair value of the derivative liability includes items subject to management’s judgment including the valuation model used in determining the fair value, as well as individual inputs to the valuation model. 52 We identified the initial accounting for and valuation of the April 2020 Notes as a critical audit matter because of the complexity in applying the accounting framework for the April 2020 Notes and the significant estimates and judgments made by management in the determination of the fair value of the derivative liability component. This required a high degree of auditor judgment and an increased extent of effort when performing audit procedures to evaluate the appropriateness of the accounting framework and to assess the reasonableness of the fair value estimates and assumptions, including the involvement of our fair value specialists. How the Critical Audit Matter Was Addressed in the Audit Our audit procedures related to the accounting for and valuation of the April 2020 Notes included the following, among others: • With the assistance of professionals in our firm having expertise in the accounting treatment for financial instruments, we evaluated the Company’s conclusions regarding the accounting treatment applied to the April 2020 Notes including the bifurcation of the embedded conversion option. • With the assistance of our fair value specialists, we evaluated the reasonableness of the valuation methodology and the significant assumptions used to determine the fair value of the derivative liability by: o o Testing the source information underlying the fair value of the derivative liability and the mathematical accuracy of the calculation. Developing a range of independent estimates and comparing those to the fair value of the derivative liability determined by management. /s/ DELOITTE & TOUCHE LLP Parsippany, New Jersey March 29, 2021 We have served as the Company's auditor since 2000. 53 SCYNEXIS, INC.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS 1. Description of Business and Basis of Preparation Organization SCYNEXIS, Inc. (“SCYNEXIS” or the “Company”) is a Delaware corporation formed on November 4, 1999. SCYNEXIS is a biotechnology company, headquartered in Jersey City, New Jersey, pioneering innovative medicines to overcome and prevent difficult-to-treat and drug-resistant infections. The Company is developing its lead product candidate, ibrexafungerp, as the first representative of a novel oral and intravenous triterpenoid antifungal family for the treatment of several fungal infections, including serious and life-threatening invasive fungal infections. The Company has incurred significant losses and negative cash flows from operations since its initial public offering in May 2014 and expects to continue to incur losses and negative cash flows for the foreseeable future. As a result, the Company had an accumulated deficit of $326.6 million at December 31, 2020 and limited capital resources to fund ongoing operations. These capital resources primarily comprised cash and cash equivalents of $93.0 million at December 31, 2020. While the Company believes its capital resources are sufficient to fund the Company’s on-going operations for a period of at least 12 months subsequent to the issuance of the accompanying consolidated financial statements, the Company's liquidity could be materially affected over this period by, among other things: (1) its ability to raise additional capital through equity offerings, debt financings, or other non-dilutive third-party funding; (2) costs associated with new or existing strategic alliances, or licensing and collaboration arrangements; (3) negative regulatory events or unanticipated costs related to its development of ibrexafungerp; (4) its ability to potentially commercialize ibrexafungerp for the treatment of vaginal yeast infections and; (5) any other unanticipated material negative events or costs. One or more of these events or costs could materially affect the Company’s liquidity. If the Company is unable to meet its obligations when they become due, the Company may have to delay expenditures, reduce the scope of its research and development programs, or make significant changes to its operating plan. The accompanying consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary. Intercompany balances and transactions are eliminated in consolidation. Shelf Registration Filings On December 31, 2020 and September 11, 2020, the Company filed shelf registration statements on Form S-3 (File No. 333-251851 and File No. 333-248751, respectively) with the Securities and Exchange Commission (“SEC”), which were declared effective on January 8, 2021 and October 1, 2020, respectively (the “January 2021 Shelf Registration” and “October 2020 Shelf Registration”). Both shelf registrations contain a base prospectus which covers the offering, issuance and sale of such indeterminate number of shares of common stock and preferred stock, such indeterminate principal amount of debt securities, and such indeterminate number of warrants to purchase common stock, preferred stock and/or debt securities, which together shall have an aggregate initial offering price not to exceed $200.0 million. A prospectus is included in the October 2020 Shelf Registration covering the offering, issuance and sale by the Company of up to a maximum aggregate offering price of $50.0 million of the Company’s common stock that may be issued and sold under a Controlled Equity OfferingSM Sales Agreement with Cantor Fitzgerald & Co. (“Cantor”) and/or Controlled Equity OfferingSM Sales Agreement with Ladenburg Thalmann & Co. Inc. (such agreements, the “Sales Agreements”). These Sales Agreements were cancelled in December 2020. As of December 31, 2020, approximately $437.0 million of the securities registered under the Company’s effective shelf registrations, which include the January 2021 Shelf Registration, October 2020 Shelf Registration, and the Form S-3 shelf registration filed by the Company in August 2018 (effective September 14, 2018), are available to be offered, issued and sold by the Company. Reverse Stock Split On July 16, 2020, the Company filed a Certificate of Amendment to its Amended and Restated Certificate of Incorporation (the “Amendment”), which became effective on Friday, July 17, 2020, (a) implementing a 1-for-10 reverse stock split of the Company’s common stock and (b) decreasing the number of authorized shares of the Company’s common stock from 250,000,000 shares to 100,000,000 shares. On the effective date of July 17, 2020, the number of the Company’s issued and outstanding shares of common stock was decreased from 105,083,291 to 10,508,302 and the par value per common share remained unchanged. No fractional shares were issued as a result of the reverse stock split. Stockholders who would otherwise have been entitled to receive a fractional share received a cash payment in lieu thereof. All share and per share amounts presented in these consolidated financial statements have been retroactively adjusted for the reverse stock split and certain items in the prior period financial statements have been revised to conform to the current presentation. 58 The reverse stock split affected all shares of the Company’s common stock outstanding immediately prior to the effective time of the reverse stock split, as well as the number of shares of common stock available for issuance under the Company’s equity incentive plans. In addition, the reverse stock split effected a reduction in the number of shares of common stock issuable upon the conversion of outstanding convertible notes or upon the exercise of stock options or warrants outstanding. Use of Estimates The preparation of the consolidated financial statements in conformity with U.S. GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates include: determination of the fair value of stock-based compensation grants; the estimate of services and effort expended by third-party research and development service providers used to recognize research and development expense; and the estimates and assumptions utilized in measuring the fair values of the warrant and derivative liabilities each reporting period. 2. 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 and cash equivalents. The Company's money market fund investment (recognized as cash and cash equivalents) is with what the Company believes to be a high quality issuer. The Company has not experienced any significant losses in the account. 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 $93.3 million and $42.2 million as of December 31, 2020 and 2019, respectively. See Note 8 for further details on the nature of the restricted cash. Short-Term Investments The Company's held-to-maturity investments in U.S. government securities, commercial paper, and its overnight repurchase agreement 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. Warrant Liabilities The Company accounts for the outstanding warrants associated with the June 2016 public offering, March 2018 Public Offering, December 2019 Public Offering and December 2020 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. See Notes 9 and 12 for further details. Convertible Debt and Derivative Liabilities In connection with the Company’s issuance of its April 2020 and March 2019 6.0% Convertible Senior Notes (the “April 2020 Notes” and 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 long-term derivative liabilities in the Company’s balance sheet in accordance with FASB Accounting Standards Codification (“ASC”) 815, Derivatives and Hedging. The convertible debt and the derivative liabilities associated with the April 2020 Notes and March 2019 Notes are presented in total on the consolidated balance sheet as the convertible debt and derivative liabilities. The convertible debt is carried at amortized cost. The derivative liabilities 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 Notes 7 and 12 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 59 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 which comprised issuance costs and an advisory fee. 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. Debt issuance costs allocated to the derivative liabilities were included in other expense as a component of the fair value adjustment for the year ended December 31, 2020. The Company’s previous term loan with Solar Capital Ltd. (“Solar”), which was paid in full in March 2019 (see Note 7), 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 term loan. The resulting debt discount was being amortized over the term of the term loan using the straight-line method, which approximated 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, and directors 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-employee directors 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. Basic and Diluted Net Loss per Share of Common Stock The Company calculates net loss per common share in accordance with ASC 260, Earnings Per Share. Basic and diluted net loss per common share was determined by dividing net loss applicable to common stockholders by the weighted average number of common shares outstanding during the period. 60 The following potentially dilutive shares of common stock have not been included in the computation of diluted net loss per share for all periods as the result would be anti-dilutive: Outstanding stock options Outstanding restricted stock units Warrants to purchase common stock associated with June 2016 Public Offering Warrants to purchase common stock associated with March 2018 Public Offering - Series 2 Warrants to purchase common stock associated with December 2019 Public Offering Option to purchase common stock associated with December 2019 Public Offering Warrants to purchase common stock associated with December 2020 Public Offering - Series 1 Warrants to purchase common stock associated with December 2020 Public Offering - Series 2 For possible future issuance for the conversion of the March 2019 Notes For possible future issuance for the conversion of the April 2020 Notes Warrants to purchase common stock associated with Solar loan agreement Total Segment and Geographic Information December 31, 2020 2019 830,343 29,087 421,867 798,810 4,472,205 — 6,800,000 6,800,000 1,138,200 1,299,790 12,243 22,602,545 526,070 96,637 421,867 798,810 4,472,205 583,333 — — 1,138,200 — 12,243 8,049,365 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, 2020 and 2019. 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 R-Pharm outside of the United States for the year ended December 31, 2019. All of the Company's revenue in 2019 was generated from a non-refundable upfront payment received under a licensing and collaboration arrangement with a partner located in Russia. All sales, including sales outside of the United States, are denominated in United States dollars. Recently Issued 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. As a smaller reporting company, the Company is currently evaluating the impact ASU 2016-13 will have on its consolidated financial statements. In December 2019, the FASB issued ASU No. 2019-12, Income Taxes: Simplifying the Accounting for Income Taxes (“ASU 2019-12”). ASU 2019-12 simplifies the accounting for income taxes, eliminates certain exceptions within ASC 740, Income Taxes, and clarifies certain aspects of the current guidance to promote consistency among reporting entities. This guidance will be effective for the Company in the first quarter of 2021 on a prospective basis, and early adoption is permitted. The Company is currently evaluating the impact ASU 2019-12 will have on its consolidated financial statements. 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. As a smaller reporting company, the Company is currently evaluating the impact ASU 2020-06 will have on its consolidated financial statements. 61 Recently Adopted Accounting Pronouncements In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”). ASU 2018-13 removes, modifies and adds certain disclosure requirements in ASU 2018-13, Fair Value Measurement. ASU 2018-13 eliminates certain disclosures related to transfers and the valuation process, modifies disclosures for investments that are valued based on net asset value, clarifies the measurement uncertainty disclosure, and requires additional disclosures for Level 3 fair value measurements. ASU 2018-13 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The Company adopted ASU 2018-13 during the year ended December 31, 2020 and as a result, included the required additional disclosures for its Level 3 fair value measurements in its consolidated financial statements (see Note 12). The Company did not identify any other material impacts of ASU 2018-13 on its consolidated financial statements. 3.

Borrowings April 2020 Note Purchase Agreement December 31, 2020 2019 $ $ 991 $ 2,190 960 4,141 $ 1,296 1,798 707 3,801 On April 9, 2020, the Company entered into a Senior Convertible Note Purchase Agreement (the “April 2020 Note Purchase Agreement”) and issued and sold to Puissance Life Science Opportunities Fund VI (“Puissance”) $10.0 million aggregate principal amount of its April 2020 Notes, resulting in net proceeds of approximately $9.5 million after deducting $0.5 million for an advisory fee and other issuance costs The April 2020 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 April 2020 Notes being issued to one financially sophisticated investor. The April 2020 Notes will bear interest at a rate of 6.0% per annum, payable semiannually in arrears on April 15 and October 15 of each year, beginning October 15, 2020. The April 2020 Notes will mature on April 15, 2026, unless earlier converted, redeemed or repurchased. The April 2020 Notes constitute general, senior unsecured obligations of the Company. As of December 31, 2020, the Company’s April 2020 Notes consists of the convertible debt balance of $1.2 million, presented net of the unamortized debt issuance costs allocated to the convertible debt of $0.1 million, and the bifurcated embedded conversion option derivative liability of $3.3 million. In connection with the Company’s issuance of its April 2020 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 $8.1 million as the interest make-whole provision is settled in shares of common stock. Debt issuance costs of $0.4 million initially allocated to the derivative liability were written off upon issuance of the April 2020 Notes and were recognized in the gain on the fair value adjustment for the derivative liability for the year ended December 31, 2020. For the year ended December 31, 2020, the Company recognized a gain of $1.7 million on the fair value adjustment for the derivative liability and recognized $0.2 million in amortization of debt issuance costs and discount for the year ended December 31, 2020, related to the April 2020 Notes. In June 2020, Puissance converted $2.0 million of the April 2020 Notes for 316,461 shares of common stock. Upon conversion of the $2.0 million of the April 2020 Notes, the Company recognized a $0.8 million extinguishment loss which represents the difference between the total net carrying amount of the convertible debt and derivative liability of $2.0 million and the fair value of the consideration issued of $2.8 million. In December 2020 and January 2021, Puissance converted the remaining $2.0 million and $6.0 million of the April 2020 Notes for 322,348 and 959,080 shares of common stock, respectively. Upon conversion of the $2.0 million of the April 2020 Notes in December 2020, the Company recognized a $1.0 million extinguishment loss which represents the difference between the total net carrying amount of the convertible debt and derivative liability of $1.4 million and the fair value of the consideration issued of $2.4 million. The Company estimated the fair value of the convertible debt and derivative liability for the April 2020 Notes using a binomial lattice valuation model and Level 3 inputs. At December 31, 2020, the fair value of the April 2020 Notes is $7.4 million. The holders of the April 2020 Notes may convert their April 2020 Notes at their option at any time prior to the close of business on the business day immediately preceding April 15, 2026 into shares of the Company’s common stock. The initial conversion rate is 111.1108 shares of common stock per $1,000 principal amount of the April 2020 Notes, which is equivalent to an initial conversion price of approximately $9.00 per share, and is subject to adjustment in certain events described in the April 2020 Note Purchase Agreement. Holders who convert may also be entitled to receive, under certain circumstances, an “interest make-whole payment” (as defined in the April 2020 Note Purchase Agreement) 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 for a holder who elects to convert its April 2020 Notes in connection with such a corporate event. Unless the Company seeks and receives stockholder approval, the number of shares that the Company may deliver in connection with a conversion of the April 2020 Notes, including those delivered in connection with an “interest make-whole payment” or a “make-whole fundamental change” (each as defined in the April 2020 Note Purchase Agreement), will not exceed a cap of 1,938,600 shares of common stock. 63 On or after April 15, 2023, the Company has the right, at its election, to redeem all or any portion of the April 2020 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 April 2020 Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. If a “fundamental change” (as defined in the April 2020 Note Purchase Agreement) occurs, then, subject to certain exceptions, the Company must offer to repurchase the April 2020 Notes for cash at a repurchase price of 100% of the principal amount of the April 2020 Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the repurchase date. 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. The Company used the net proceeds to pay the remaining outstanding Solar term loan in full and recorded a loss on debt extinguishment of $0.8 million during the year ended December 31, 2019. The loss on debt extinguishment of $0.8 million for the year ended December 31, 2019 was recognized as the difference between the reacquisition price of the outstanding Solar debt of $15.9 million and the $15.1 million net carrying value of the Solar debt obligation prior to repayment. As of December 31, 2020 and 2019, the Company’s March 2019 Notes consists of the convertible debt balance of $9.4 million and $8.3 million, presented net of the unamortized debt issuance costs allocated to the convertible debt of $0.4 million and $0.5 million, and the bifurcated embedded conversion option derivative liability of $2.7 million and $3.2 million, 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. Debt issuance costs of $0.6 million initially allocated to the derivative liability were written off upon issuance of the March 2019 Notes and were recognized in the gain on the fair value adjustment for the derivative liability for the year ended December 31, 2019. For the years ended December 31, 2020 and 2019, the Company recognized gains of $0.5 million and $1.6 million, respectively, on the fair value adjustment for the derivative liability. For the years ended December 31, 2020 and 2019, the Company recognized $1.0 million and $1.1 million, respectively, in amortization of debt issuance costs and discount, related to the March 2019 Notes. In April 2019, Puissance converted $2.0 million of the March 2019 Notes for 162,600 shares of common stock. Upon conversion of the $2.0 million of the March 2019 Notes, the Company recognized a $0.2 million extinguishment loss which represents the difference between the total net carrying amount of the convertible debt and derivative liability of $2.8 million and the fair value of the consideration issued of $3.0 million. 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, 2020 and 2019, the fair value of the convertible debt and derivative liability for the March 2019 Notes is $12.9 million and $11.7 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. 64 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. Solar Loan Agreement On September 30, 2016, the Company entered into a loan agreement with Solar Capital Ltd. (“Solar”), in its capacity as administrative and collateral agent and as lender. Pursuant to the loan agreement, Solar was providing the Company with a 48-month secured term loan in the amount of $15.0 million. The term loan bore interest at a floating rate equal to the LIBOR rate in effect plus 8.49%. The Solar term loan was paid in full in March 2019. 8. 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): Operating lease cost Variable lease cost Total operating lease expense Cash paid for amounts included in the measurement of operating lease liability Remaining Lease term (years) Discount rate Years Ended December 31, 2020 2019 $ $ $ 664 51 715 $ $ 507 $ 664 41 705 497 December 31, 2020 December 31, 2019 8.59 15 % 9.59 15 % Future minimum lease payments for all operating leases as of December 31, 2020 are as follows (in thousands): 2021 2022 2023 2024 2025 Thereafter Total December 31, 2020 517 527 715 730 744 2,789 6,022 $ $ 65 The presentation of the operating lease liability and right-of-use asset as of December 31, 2020 are as follows (in thousands): Present value of future minimum lease payments Operating lease liability, current portion Operating lease liability, long-term portion Total operating lease liability Difference between future minimum lease payments and discounted cash flows Operating lease right-of-use asset License Arrangements with Potential Future Expenditures December 31, 2020 3,326 52 3,274 3,326 2,696 2,999 $ $ $ $ $ As of December 31, 2020, 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 3 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. The milestone payment was recognized in the consolidated statement of operations in research and development expense for the year ended December 31, 2019 and is included in cash used in operating activities on the consolidated statement of cash flows. 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., anticipated 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. Other License Arrangements 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, 2020 and 2019, 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. 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 and for the years ended December 31, 2020 and 2019, there was no revenue recognized by the Company associated with this agreement given the variable consideration was fully constrained. 66 9. Stockholders’ Equity Authorized, Issued, and Outstanding Common Shares The Company’s authorized common stock has a par value of $0.001 per share and consists of 100,000,000 shares as of December 31, 2020 and 2019; 19,663,698 and 9,741,372 shares were issued and outstanding at December 31, 2020, and December 31, 2019, respectively. On June 18, 2019, the Company’s stockholders approved an amendment to the Company’s Amended and Restated Certificate of Incorporation to increase the total number of authorized shares of common stock from 125,000,000 to 250,000,000. On July 16, 2020, the Company filed a Certificate of Amendment to its Amended and Restated Certificate of Incorporation, which became effective on Friday, July 17, 2020, (a) implementing a 1-for-10 reverse stock split of the Company’s common stock and (b) decreasing the number of authorized shares of the Company’s common stock from 250,000,000 shares to 100,000,000 shares. The reverse stock split affected all shares of the Company’s common stock outstanding immediately prior to the effective time of the reverse stock split, as well as the number of shares of common stock available for issuance under the Company’s equity incentive plans. In addition, the reverse stock split effected a reduction in the number of shares of common stock issuable upon the conversion of outstanding convertible notes or upon the exercise of stock options or warrants outstanding. No fractional shares were issued as a result of the reverse stock split. Shares Reserved for Future Issuance The Company had reserved shares of common stock for future issuance as follows: Outstanding stock options Outstanding restricted stock units Warrants to purchase common stock associated with June 2016 Public Offering Warrants to purchase common stock associated with March 2018 Public Offering - Series 2 Warrants to purchase common stock associated with December 2019 Public Offering Option to purchase common stock associated with December 2019 Public Offering Warrants to purchase common stock associated with December 2020 Public Offering - Series 1 Warrants to purchase common stock associated with December 2020 Public Offering - Series 2 Prefunded warrants to purchase common stock associated with December 2020 Public Offering Warrants to purchase common stock associated with Solar loan agreement For possible future issuance for the conversion of the March 2019 Notes For possible future issuance for the conversion of the April 2020 Notes For possible future issuance under 2014 Equity Incentive Plan (Note 11) For possible future issuance under Employee Stock Purchase Plan (Note 11) For possible future issuance under 2015 Inducement Award Plan (Note 11) Total common shares reserved for future issuance Liquidation Rights December 31, 2020 2019 830,343 29,087 421,867 798,810 4,472,205 — 6,800,000 6,800,000 5,260,000 12,243 1,138,200 1,299,790 146,488 5,895 14,050 28,028,978 526,070 96,637 421,867 798,810 4,472,205 583,333 — — — 12,243 1,138,200 — 55,478 7,423 31,550 8,143,816 In the event of any liquidation or dissolution of the Company, the holders of the common stock are entitled to the remaining assets of the Company legally available for distribution. Dividends and Voting Rights The holders of the common stock are entitled to receive dividends if and when declared by the Company. 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 67 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, 2020 and 2019. December 2020 Public Offering 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) pre-funded 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 pre-funded warrants, to purchase up to an aggregate of 13,600,000 shares of the Company’s common stock. The pre-funded warrants entitle the holders to purchase up to 5,260,000 shares of common stock and have an unlimited term and an exercise price of $0.001 per share. Each of the two series of warrants entitle the holders to purchase up to an aggregate of 6,800,000 shares of common stock. 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 year ended December 31, 2020 given their nominal exercise price. The Series 1 warrants have a one-year term and an exercise price of $7.33 per share, and 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 pre-funded warrants, the Series 1 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 1 and Series 2 warrants that accompany the pre-funded warrants have an additional provision, if certain beneficial ownership limitations are met, entitling the holder thereof to purchase a pre-funded warrant rather than a share of common stock at the warrant exercise price less the exercise price of the pre-funded 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 pre-funded warrants, $6.249 per pre-funded warrant and accompanying warrants. The December 2020 Public Offering resulted in approximately $79.5 million of net proceeds to the Company after deducting the underwriting discount and offering expenses. December 2019 Public Offering On December 12, 2019, the Company completed a public offering (the “December 2019 Public Offering”) of its common stock and warrants pursuant to the Company's effective Shelf Registration. The Company sold an aggregate of 3,888,888 shares of the Company’s common stock and warrants to purchase up to an aggregate of 3,888,888 shares of the Company’s common stock at a public offering price of $9.00 per share and accompanying warrant. Net proceeds from the December 2019 Public Offering were approximately $32.5 million, after deducting the underwriting discount and offering expenses. In addition, the Company granted to the underwriters an option to purchase up to 583,333 additional shares of common stock and/or warrants to purchase up to an aggregate of an additional 583,333 shares of common stock, in each case at the public offering price, less underwriting discounts and commissions. The underwriters exercised their option to purchase 583,333 warrants in December 2019. The option to purchase up to 583,333 additional shares of common stock was not exercised by the underwriters and the option expired in January 2020. The warrants to purchase shares of common stock are immediately exercisable and expire on the earlier of (i) such date that is six months after the Company publicly announces the approval from the U.S. Food and Drug Administration for ibrexafungerp for the treatment of vulvovaginal candidiasis and (ii) June 12, 2023, and have an exercise price of $11.0 per share. There is not expected to be any trading market for the warrants. Each warrant is exercisable immediately upon issuance, subject to certain limitations on beneficial ownership. March 2018 Public Offering On March 8, 2018, the Company completed a public offering (the “March 2018 Public Offering”) of its common stock and warrants pursuant to the Company’s effective shelf registration. The Company sold an aggregate of 1,775,150 shares of the Company’s common stock and warrants to purchase up to 2,130,180 shares of the Company’s common stock at a public offering price of $16.90 per share. Each purchaser received a warrant to purchase 0.75 of a share of common stock (the “March 2018 Series 1 warrants”) and 0.45 of a share of common stock (the “March 2018 Series 2 warrants”) for each share purchased in the March 2018 Public Offering. The March 2018 Series 1 warrants to purchase in the aggregate up to 1,331,370 shares of common stock had a 53-week term and an exercise price of $18.5 per share, and the March 2018 Series 2 warrants to purchase in the aggregate up to 798,810 shares of common stock have a five-year term and an exercise price of $20.0 per share. There is not expected to be any market for the warrants and each warrant is exercisable immediately upon issuance, subject to certain limitations on 68 beneficial ownership. During the year ended December 31, 2019, there were 11,550 of the March 2018 Series 1 warrants exercised for total proceeds of $0.2 million and the March 2018 Series 1 warrants expired on March 14, 2019. June 2016 Public Offering On June 21, 2016, the Company completed a public offering (the “June 2016 Public Offering”) and sold 937,500 shares of its common stock and warrants to purchase up to 421,867 shares of the Company’s common stock. Each purchaser received a warrant to purchase 0.45 of a share for each share purchased in the June 2016 Public Offering. There is not expected to be any trading market for the warrants. Each warrant was exercisable immediately upon issuance, will expire five years from the date of issuance, and has an exercise price of $30.0 per share. Warrant Liabilities The June 2016, March 2018, December 2019, and December 2020 warrants 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 June 2016 and December 2020 Series 1 warrant liabilities are recorded as current liabilities in the accompanying consolidated balance sheet. During the years ended December 31, 2020 and 2019, the Company recorded losses of $5.2 million and $4.5 million, respectively, due to the change in fair value of the warrant liabilities. Issuance costs of $1.9 million and $1.0 million initially allocated to the December 2020 Public Offering and December 2019 Public Offering warrant liabilities, respectively, were written off upon settlement and were recognized in the loss on the fair value adjustment for the warrant liabilities for the years ended December 31, 2020 and 2019, respectively. As of December 31, 2020, the fair value of the warrant liabilities was $51.2 million. Common Stock Purchase Agreement On April 10, 2020, the Company entered into the Common Stock Purchase Agreement with Aspire Capital pursuant to which the Company has 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 over the next 30 months, subject to certain limitations and conditions set forth in the Common Stock Purchase Agreement. The aggregate number of shares that we can sell to Aspire Capital under the Common Stock Purchase Agreement may in no case exceed 1,956,547 shares of the Company’s common stock (which is equal to approximately 19.99% of the common stock outstanding on the date of the Common Stock Purchase Agreement), including the 70,910 commitment shares (the Exchange Cap), unless either (a) shareholder approval is obtained to issue more, in which case the Exchange Cap will not apply, or (b) the average purchase price of all shares sold under the Common Stock Purchase Agreement exceeds $8.461; provided that at no time shall Aspire Capital (together with its affiliates) beneficially own more than 19.99% of the Company’s common stock. During the year ended December 31, 2020, the Company sold 125,000 shares of its common stock under the Common Stock Purchase Agreement for gross proceeds of $0.6 million. Under the Common Stock Purchase Agreement, on any trading day selected by the Company, the Company has the right, in its sole discretion, to present Aspire Capital with a purchase notice (each, a “Purchase Notice”), directing Aspire Capital (as principal) to purchase up to 25,000 shares of Common Stock per business day, up to $20.0 million of common stock in the aggregate at a per share price (the “Purchase Price”) equal to the lesser of: • the lowest sale price of Common Stock on the purchase date; or • the arithmetic average of the three (3) lowest closing sale prices for Common Stock during the ten (10) consecutive trading days ending on the trading day immediately preceding the purchase date. The Company and Aspire Capital also may mutually agree to increase the number of shares that may be sold to as much as an additional 200,000 shares per business day. In addition, on any date on which the Company submits a Purchase Notice to Aspire Capital in an amount equal to at least 25,000 shares, the Company also has the right, in its sole discretion, to present Aspire Capital with a volume-weighted average price purchase notice (each, a “VWAP Purchase Notice”) directing Aspire Capital to purchase an amount of stock equal to up to 30% of the aggregate shares of Common Stock traded on its principal market on the next trading day (the “VWAP Purchase Date”), subject to a maximum number of shares the Company may determine. The purchase price per share pursuant to such VWAP Purchase Notice is generally the lessor of (i) the closing sale price on the VWAP Purchase Date, or (ii) 97% of the volume-weighted average price for common stock traded on its principal market on the VWAP Purchase Date. The Purchase Price will be adjusted for any reorganization, recapitalization, non-cash dividend, stock split, or other similar transaction occurring during the period(s) used to compute the Purchase Price. The Company may deliver multiple Purchase Notices and VWAP Purchase Notices to Aspire Capital from time to time during the term of the Common Stock Purchase Agreement, so long as the most recent purchase has been completed. 69 The Common Stock Purchase Agreement provides that the Company and Aspire Capital shall not effect any sales under the Common Stock Purchase Agreement on any purchase date where the closing sale price of common stock is less than $0.25. There are no trading volume requirements or restrictions under the Common Stock Purchase Agreement, and the Company will control the timing and amount of sales of common stock to Aspire Capital. Aspire Capital has no right to require any sales by the Company, but is obligated to make purchases from the Company as directed by the Company in accordance with the Common Stock Purchase Agreement. There are no limitations on use of proceeds, financial or business covenants, restrictions on future fundings, rights of first refusal, participation rights, penalties or liquidated damages in the Common Stock Purchase Agreement. In consideration for entering into the Common Stock Purchase Agreement, concurrently with the execution of the Common Stock Purchase Agreement, the Company issued to Aspire Capital 70,910 shares of common stock (the “Commitment Shares”). The fair value of the Commitment Shares of $0.6 million was recognized in other expense in the consolidated statements of operations for the year ended December 31, 2020. The Common Stock Purchase Agreement may be terminated by the Company at any time, at its discretion, without any cost to the Company. Aspire Capital has agreed that neither it nor any of its agents, representatives and affiliates shall engage in any direct or indirect short-selling or hedging of common stock during any time prior to the termination of the Common Stock Purchase Agreement. Any proceeds that the Company receives under the Common Stock Purchase Agreement are expected to be used for general corporate purposes, including working capital. Warrant Associated with Solar Loan Agreement Pursuant to a loan agreement, the Company issued to Solar a warrant to purchase an aggregate of up to 12,243 shares of the Company’s common stock at an exercise price of $36.754 per share. The warrant will expire five years from the date of the grant. The warrant was classified as equity and recorded at its relative fair value at issuance in the stockholders’ equity section of the balance sheet. 10. Income Taxes The Company’s consolidated financial statements include a total tax benefit of $3.1 million and zero on loss before taxes of $58.3 million and $53.7 million for the years ended December 31, 2020 and 2019, respectively, and was generated entirely in the United States and Australia. Reconciliations of the differences between the benefit for income taxes and income taxes at the statutory U.S. federal income tax rate is as follows (dollars in thousands): 2020 2019 Amount Percent of Pretax Income Amount Percent of Pretax Income Income taxes from continuing operations at statutory rate State income taxes State effect of permanent items Stock-based compensation Deferred rate change Warrants issuance Other NOL sale R&D credit adjustment Increase in valuation allowance Total income tax benefit $ $ (12,250 ) (4,108 ) 78 96 — 131 206 301 2 12,396 (3,148 ) 21.0 % 7.0 % (0.1 )% (0.2 )% — (0.2 )% (0.3 )% (0.5 )% — (21.3 )% 5.4 % $ $ (11,279 ) (3,778 ) 285 100 (905 ) 733 883 — (2,760 ) 16,721 — The components of deferred tax assets and liabilities as of December 31, 2020 and 2019 are as follows (in thousands): Noncurrent deferred tax assets (liabilities) Accrued expenses Stock-based compensation Lease liability Other Net operating loss carryforwards Research and development credits Total deferred tax assets Valuation allowances Net deferred tax assets December 31, 2020 2019 $ 148 $ 2,591 935 (823 ) 70,936 5,291 79,078 (79,078 ) $ — $ 70 21.0 % 7.0 % (0.5 )% (0.2 )% 1.6 % (1.4 )% (1.5 )% — 5.1 % (31.1 )% — % 107 2,436 945 (856 ) 58,073 5,984 66,689 (66,689 ) — As of December 31, 2020 and 2019, the Company had available federal net operating loss (“NOL”) carryforwards of approximately $294.4 million and $242.4 million, respectively, and state and net operating loss carryforwards of approximately $202.7 million and $178.2 million, respectively. Approximately $169.6 million of the federal NOLs can be carried forward to future tax years and expire at various times through 2037. The federal NOLs generated in December 31, 2020 and 2019 of approximately $52.0 million and $47.5 million, respectively, are carried forward indefinitely and do not expire. The Company’s state and net operating loss carryforwards began to expire in 2019. As of December 31, 2020, the Company had available federal research and development credit carryforwards of $5.3 million which begin to expire in 2022. 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 up to a maximum lifetime benefit of $20.0 million per business. As of December 31, 2020, the Company has received approximately $9.9 million under the program. In April 2020, the Company received a cash receipt of approximately $3.1 million, from the sale of its state NOLs and research and development credits and recognized an income tax benefit of $3.1 million for the year ended December 31, 2020 in the 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, 2020 and 2019, 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. In accordance with Section 382 of the Internal Revenue Code of 1986, as amended, a change in equity ownership of greater than 50% within a three-year period results in an annual limitation on the Company’s ability to utilize its NOL carryforwards created during the tax periods prior to the change in ownership. The Company has determined that ownership changes have occurred and as a result, a portion of the Company’s NOL carryforwards are limited. Because the Company has incurred cumulative net operating losses since inception, all tax years remain open to examination by U.S. federal and state income tax authorities. 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, 2020 and 2019 (in thousands): Unrecognized tax benefit—January 1 Additions for tax positions of current period Additions for tax positions of prior periods Deferred rate change Unrecognized tax benefit—December 31 December 31, 2020 2019 $ $ 436 $ — — — 436 $ 436 — — — 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. 11. 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 71 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 and February 25, 2015, 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, 2020 and 2019, the Company automatically added 389,650 and 191,887 shares to the total number shares of common stock available for future issuance under the 2014 Plan, respectively. As of December 31, 2020, there were 146,488 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, 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 shares of common stock. During the year ended December 31, 2020, there were 17,500 granted options of the Company’s common stock under the 2015 Plan. As of December 31, 2020, there were 14,050 shares of common stock available for future issuance under the 2015 Plan. During the year ended December 31, 2019, there were 11,500 granted options of the Company’s common stock under the 2015 Plan. As of December 31, 2019, there were 31,550 shares of common stock available for future issuance under the 2015 Plan. 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. 72 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 2020 and 2019 was $4.83 and $7.50 per option, respectively. The aggregate fair value of options granted during 2020 and 2019 was $1.7 million and $1.3 million, respectively. The assumptions used to estimate fair value and the resulting grant date fair values are as follows: Weighted average expected volatility Weighted average risk-free interest rate Weighted average expected term (in years) Employees Years Ended December 31, 2020 2019 Non-employee Directors Years Ended December 31, 2020 2019 64.67 % 1.18 % 5.97 66.47 % 2.47 % 6.03 66.55 % 0.36 % 5.50 65.36 % 2.11 % 5.54 The activity for the 2009 Plan, 2014 Plan and 2015 Plan for the years ended December 31, 2020 is summarized as follows: Outstanding — December 31, 2019 Granted Exercised Forfeited/expired Outstanding — December 31, 2020 Exercisable — December 31, 2020 Vested or expected to vest —December 31, 2020 Number of Shares Weighted- Average Exercise Price Weighted- Average Remaining Contractual Life (in years) Aggregate Intrinsic Value ($000) 526,070 $ 349,437 $ (166 ) $ (44,998 ) $ 830,343 $ 447,802 $ 830,343 $ 30.55 8.17 8.60 23.50 21.52 31.47 21.52 7.62 $ 7.71 $ 6.74 $ 7.71 $ 60 96 22 96 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, 2020, and the exercise price multiplied by the number of options). The total fair value of shares vested for both the years ended December 31, 2020 and 2019 was $1.3 million and $1.5 million, respectively. As of December 31, 2020, there was approximately $2.0 million of total unrecognized compensation cost related to unvested share-based compensation arrangements granted under the plan. That cost is expected to be recognized over a weighted-average period of 2.4 years. Restricted stock unit ("RSU") activity under the 2014 Plan and 2015 Plan for the years ended December 31, 2020, is summarized as follows: Non-vested at December 31, 2019 Granted Vested Forfeited Non-vested at December 31, 2020 Number of Shares 96,637 $ 28,695 $ (78,859 ) $ (17,386 ) $ 29,087 $ Weighted Average Grant Date Fair Value Per Share 14.18 8.18 14.05 12.68 9.52 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, 2020, there was approximately $0.2 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 2.8 years. 73 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. Common stock that may be issued under the 2014 ESPP will not exceed 4,779 shares, plus the number of shares of common stock that are automatically added on January 1st of each year for a period of ten years, commencing on January 1, 2015 and ending on January 1, 2024, in an amount equal to the lesser of (i) 0.8% of the total number of shares of outstanding common stock on December 31 of the preceding calendar year, and (ii) 2,941 shares of common stock. Similar to the 2014 Plan, 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. 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, 2020 and 2019, the Company issued 4,497 and 3,684 shares of common stock under the 2014 ESPP, respectively. During the years ended December 31, 2020 and 2019, the number of shares of common stock available for issuance under the ESPP was automatically increased by 2,941 shares. As of December 31, 2020, there were 5,895 shares of common stock available for future issuance under the 2014 ESPP. 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 $2.2 million and $1.8 million for the years ended December 31, 2020 and 2019, respectively. 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, 2020 and 2019, respectively. Cash received from options exercised was $2,000 and $12,000 for the years ended December 31, 2020 and 2019, respectively. Stock-based compensation expense related to stock options is included in the following line items in the accompanying statements of operations (in thousands): Research and development Selling, general and administrative Total stock-based compensation expense 12. Fair Value Measurements Years Ended December 31, 2020 2019 $ $ 806 $ 1,414 2,220 $ 604 1,224 1,828 The carrying amounts of certain financial instruments, including cash and cash equivalents, 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. 74 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, 2020 and 2019 for financial instruments measured at fair value on a recurring basis (in thousands): December 31, 2020 Cash Restricted cash Money market funds Total assets Warrant liabilities Derivative liabilities Total liabilities December 31, 2019 Cash Restricted cash Money market funds Total assets Warrant liabilities Derivative liability Total liabilities Balance Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Fair Value Hierarchy Classification $ $ $ $ $ $ $ $ 117 $ 273 92,924 93,314 $ 51,156 5,954 57,110 23 $ 273 41,897 42,193 $ 18,396 3,192 21,588 117 273 92,924 93,314 — — — 23 273 41,897 42,193 — — — — — — — $ — — $ — — — — — $ — $ — — — — 51,156 5,954 57,110 — — — — 18,396 3,192 21,588 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. 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 volatility of the Company, using its closing common stock prices, is utilized to reflect future volatility over the expected term of the warrants. At December 31, 2020, the range and weighted average of the Level 3 volatilities utilized in the Black-Scholes model to fair value the warrant liabilities were 71.8% to 86.6% and 78.0%, respectively. Additionally, the expected term associated with the December 2019 Public Offering warrants is an unobservable input given that the expiration of the warrants is the earlier of (i) such date that is six months after the Company publicly announces the approval from the U.S. Food and Drug Administration for ibrexafungerp for the treatment of vulvovaginal candidiasis and (ii) June 12, 2023. The Company utilized a probability assessment to estimate the likelihood of occurrence for the two potential expiration dates and allocated the probability of occurrence percentage to the fair values calculated based on the two potential expected terms. The weighted average expected term is 1.2 years as of December 31, 2020 for the December 2019 Public Offering warrants with a range of 0.9 to 2.5 years. 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 liabilities are adjusted equity volatility, market credit spread, and estimated yield. As of December 31, 2020, these inputs were 58.1%, 1,458 basis points, and 14.9%, respectively. The range of volatilities were 56.5% to 60.1%. The senior convertible notes are initially fair valued using the binomial lattice model and 75 with the straight debt fair value calculated using the discounted cash flow method. The discount for lack of marketability, 7.0% as of December 31, 2020, is applied to the value of the March 2019 Notes. The residual difference represents the fair value of the embedded derivative liabilities 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): Balance – January 1, 2020 December 2020 Public Offering Loss adjustment to fair value Balance – December 31, 2020 Balance – January 1, 2020 Bifurcated embedded conversion option associated with April 2020 Notes Adjustment for partial conversion of April 2020 Notes Gain adjustment to fair value Balance – December 31, 2020 13. Employee Benefit Plan Warrant Liabilities 18,396 29,478 3,282 51,156 Derivative Liabilities 3,192 8,110 (2,690 ) (2,658 ) 5,954 $ $ $ $ The Company has a 401(k) retirement plan, which covers all U.S. employees scheduled for and working more than 20 hours per week. The Company may provide a discretionary match with a maximum amount of 50% of the first 6% of eligible participant’s compensation, which vests ratably over four years. Contributions under the plan were approximately $0.1 million for the years ended December 31, 2020 and 2019. 14. Subsequent Events Pursuant to the terms of the 2014 Plan (see Note 11), on January 1, 2021, the Company automatically added 786,547 shares to the total number shares of common stock available for future issuance under the 2014 Plan. Pursuant to the terms of the 2014 ESPP (see Note 11), on January 1, 2021, the Company automatically added 2,941 shares to the total number shares of common stock available for future issuance under the 2014 ESPP. In January 2021, Puissance converted the remaining $6.0 million of the April 2020 Notes for 959,080 shares of common stock. In February 2021, the Company partnered with Amplity Inc. (“Amplity”) for the potential upcoming commercial launch of ibrexafungerp for the treatment of VVC. Under the terms of the 5-year agreement, the Company will utilize the Amplity’s commercial execution expertise and resources for sales force, remote engagement, training, market access and select operations services. The Company will maintain full ownership of ibrexafungerp and control of all strategic aspects of the launch. Amplity is deferring a portion of its direct service costs in the first two years (2021 and 2022), which the Company will repay over three years starting in 2023. Amplity has the potential to earn a performance-based success fee in the 2023-2025 time frame by exceeding certain revenue targets. On February 11, 2021, the Company entered into an Exclusive License and Collaboration Agreement with Hansoh (Shanghai) Health Technology Co., Ltd., and Jiangsu Hansoh Pharmaceutical Group Company Limited (collectively, “Hansoh”), pursuant to which Hansoh obtains an exclusive license from the Company to research, develop and commercialize ibrexafungerp in the Greater China region, including mainland China, Hong Kong, Macau, and Taiwan. Under the terms of the agreement, Hansoh shall be responsible for the development, regulatory approval and commercialization of ibrexafungerp in Greater China. The Company received a $10 million upfront payment and will also be eligible to receive up to $112 million in development and commercial milestones, plus 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. 76 ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE None. ITEM 9A. CONTROLS AND PROCEDURES Management’s Evaluation of our Disclosure Controls and Procedures 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, 2020, 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, 2020, our disclosure controls and procedures were effective at the reasonable assurance level. Management’s Report on Internal Control over Financial Reporting 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, 2020. Changes in Internal Control Over Financial Reporting During the quarter ended December 31, 2020, 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 over financial reporting.

DESCRIPTION OF COMMON STOCK Exhibit 4.2 SCYNEXIS, Inc. (“we,” “our,” “us,” or the “Company,”) has one class of securities registered under Section 12 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”): our common stock. The following description of our common stock does not purport to be complete and is subject in all respects to applicable Delaware law and to the provisions of our amended and restated certificate of incorporation, and our amended and restated bylaws. General Our amended and restated certificate of incorporation provides for common stock and authorized shares of undesignated preferred stock, the rights, preferences and privileges of which may be designated from time to time by our board of directors. Our authorized capital stock consists of 105,000,000 shares, all with a par value of $0.001 per share, of which 100,000,000 shares are designated as common stock and 5,000,000 shares are designated as preferred stock. Common Stock Voting Rights. Each holder of our common stock is entitled to one vote for each share of common stock held on all matters submitted to a vote of stockholders, except as otherwise expressly provided in our amended and restated certificate of incorporation or required by applicable law. Cumulative voting for the election of directors is not provided for in our amended and restated certificate of incorporation, which means that the holders of a majority of our shares of common stock can elect all of the directors then standing for election. Dividends and Distributions. Subject to preferences that may apply to any shares of preferred stock outstanding at the time, the holders of outstanding shares of our common stock are entitled to receive dividends out of funds legally available if our board of directors, in its sole discretion, determines to issue dividends and only then at the times and in the amounts that our board of directors may determine. Liquidation Rights. Upon our liquidation, dissolution or winding-up, the assets legally available for distribution to our stockholders would be distributable ratably among the holders of our common stock and any participating preferred stock outstanding at that time after payment of liquidation preferences, if any, on any outstanding shares of preferred stock and payment of other claims of creditors. The rights, preferences, and privileges of holders of our common stock are subject to, and may be adversely affected by, the rights of holders of shares of any series of preferred stock that we may designate and issue in the future. Preemptive or Similar Rights. Our common stock is not entitled to preemptive rights and is not subject to conversion, redemption or sinking fund provisions. Anti-Takeover Provisions Certificate of Incorporation and Bylaws Because our stockholders do not have cumulative voting rights, our stockholders holding a majority of the voting power of our shares of common stock outstanding will be able to elect all of our directors. Our amended and restated certificate of incorporation and amended and restated bylaws provide that all stockholder actions must be effected at a duly called meeting of stockholders and not by consent in writing. A special meeting of stockholders may be called only by a majority of our whole board of directors, the chair of our board of directors, or our chief executive officer. Our amended and restated certificate of incorporation further provides that the affirmative vote of holders of at least sixty-six and two-thirds percent (66-2/3%) of the voting power of all of the then outstanding shares of voting stock, voting as a single class, are required to amend certain provisions of our certificate of incorporation, including provisions relating to the size of the board, removal of directors, special meetings, actions by written consent and cumulative voting. The affirmative vote of holders of at least sixty-six and two-thirds percent (66-2/3%) of the voting power of all of the then outstanding shares of voting stock, voting as a single class, is required to amend or repeal our bylaws, although our bylaws may be amended by a simple majority vote of our board of directors. The foregoing provisions will make it more difficult for our existing stockholders to replace our board of directors as well as for another party to obtain control of our company by replacing our board of directors. Since our board of directors has the power to retain and discharge our officers, these provisions could also make it more difficult for existing stockholders or another party to effect a change in management. In addition, the authorization of undesignated preferred stock makes it possible for our board of directors to issue preferred stock with voting or other rights or preferences that could impede the success of any attempt to change the control of our company. These provisions are intended to enhance the likelihood of continued stability in the composition of our board of directors and its policies and to discourage certain types of transactions that may involve an actual or threatened acquisition of our company. These provisions are also designed to reduce our vulnerability to an unsolicited acquisition proposal and to discourage certain tactics that may be used in proxy rights. However, these provisions could have the effect of discouraging others from making tender offers for our shares and may have the effect of deterring hostile takeovers or delaying changes in control of our company or our management. As a consequence, these provisions also may inhibit fluctuations in the market price of our stock that could result from actual or rumored takeover attempts. Section 203 of the Delaware General Corporation Law We are subject to Section 203 of the Delaware General Corporation Law, which prohibits a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years after the date that such stockholder became an interested stockholder, with the following exceptions: • • • • • • • • before such date, the board of directors of the corporation approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder; upon closing of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction began, excluding for purposes of determining the voting stock outstanding (but not the outstanding voting stock owned by the interested stockholder) those shares owned by (1) persons who are directors and also officers and (2) employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or on or after such date, the business combination is approved by the board of directors and authorized at an annual or special meeting of the stockholders, and not by written consent, by the affirmative vote of at least 66 2/3% of the outstanding voting stock that is not owned by the interested stockholder. In general, Section 203 defines business combination to include the following: any merger or consolidation involving the corporation and the interested stockholder; any sale, transfer, pledge or other disposition of 10% or more of the assets of the corporation involving the interested stockholder; subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder; any transaction involving the corporation that has the effect of increasing the proportionate share of the stock or any class or series of the corporation beneficially owned by the interested stockholder; or the receipt by the interested stockholder of the benefit of any loss, advances, guarantees, pledges or other financial benefits by or through the corporation. In general, Section 203 defines an “interested stockholder” as an entity or person who, together with the person’s affiliates and associates, beneficially owns, or within three years prior to the time of determination of interested stockholder status did own, 15% or more of the outstanding voting stock of the corporation. FOURTH AMENDMENT TO TERMINATION AND LICENSE AGREEMENT Exhibit 10.30 THIS FOURTH AMENDMENT TO TERMINATION AND LICENSE AGREEMENT (the “ Fourth Amendment”) is made and entered into as of December 2, 2020 by and between Merck Sharp & Dohme Corp., a New Jersey corporation with a place of business at One Merck Drive, Whitehouse Station, NJ 08889 (“Merck”) and SCYNEXIS, Inc., a Delaware corporation with a principal place of business at 1 Evertrust Plaza, 13th Floor, Jersey City, NJ 07302 (“Scynexis”).
