Sahar, Ashley, Katlyn: Experienced Postpartum Depression (PPD)
2 0 2 4  
A N N U A L  
R E P O R T

Sage remains dedicated to our mission to pioneer 
solutions to deliver life-changing brain health 
medications so every person can thrive. Neurological 
diseases are the leading cause of disability worldwide, 
placing enormous burden on patients, their families, and 
healthcare systems. Our mission has never been more 
important, and we are acting with a sense of urgency to 
deliver innovative medicines to patients and better serve 
the needs of providers.
Executed Launch Strategy to Build Commercial 
Momentum for ZURZUVAE in PPD
2024 marked the first full year following the commercial 
launch of ZURZUVAE® (zuranolone), the first and only 
oral treatment approved by the FDA for adults with 
postpartum depression (PPD). We are energized by 
the impact we are already having on women with PPD 
with approximately 6,600 ZURZUVAE prescriptions 
shipped in 2024. We believe this reflects the medical 
need and growing demand for new treatments for 
women with PPD. 
Importantly, we are beginning to see a broader paradigm 
shift in practice patterns among OBGYNs who are at 
the forefront of peripartum care and continue to be the 
primary prescribers of ZURZUVAE. With the availability 
of ZURZUVAE, among OBGYNs that have prescribed, 
we have seen an increase in their rate of diagnosis and 
treatment of women with PPD. 
We have also made meaningful progress with payors to 
secure coverage for 95% of commercial and Medicaid 
patients as well as to reduce step edits or complex prior 
authorization requirements. 
We are encouraged by the strength of ZURZUVAE’s 
launch momentum as a treatment for women with PPD 
and remain focused on establishing ZURZUVAE as the 
standard of care for this devastating medical condition.
Restructured our Business and Refocused 
our Pipeline
Turning to our pipeline, in response to clinical 
setbacks, we have recalibrated our R&D efforts to 
focus on neuropsychiatry and neurodevelopmental 
disorders — areas we believe have the greatest potential 
for value creation. 
SAGE-319, our wholly-owned extrasynaptic-preferring 
GABAA receptor positive allosteric modulator (PAM), 
is currently being investigated as a potential treatment 
for behavioral symptoms associated with certain 
neurodevelopmental disorders. Our goal is to alleviate 
the high burden caused by behavioral symptoms 
associated with these disorders. We expect to share 
data from a Phase 1 multiple ascending dose (MAD) 
study by late 2025. 
Our preclinical stage work is centered on our NMDA 
receptor negative allosteric modulator (NAM) platform, 
including SAGE-817 and SAGE-039, focusing on 
potential treatments for neurodevelopmental disorders.
We are also evaluating SAGE-324, a GABAA receptor 
PAM, for potential indications, including seizures in 
developmental and epileptic encephalopathies.
With our commercial focus, prioritized pipeline and 
balance sheet as of December 31, 2024, we have a cash 
runway expected to support our operations to mid-2027.
Looking Ahead to 2025
Looking ahead, we are focused on executing our core 
priorities and evaluating alternatives to create value 
for shareholders and advance care in brain health. 
Our achievements would not be possible without 
the tremendous efforts of our Sage colleagues and 
collaborators. There is significant opportunity for 
Sage to make critical progress for patients around the 
world suffering from brain health disorders, and we 
look forward to continuing the great work underway, 
including accelerating progress in maternal mental 
health and helping many more women with PPD receive 
treatment with ZURZUVAE. Thank you for your ongoing 
support as we strive to introduce a new era of brain 
health medicines.

Summary of Risks Related to our Business
Our business, prospects, financial condition, and operating results are subject to numerous risks and uncertainties 
that you should be aware of before making an investment decision, as more fully described under Part I, Item 1A, Risk 
Factors and elsewhere in this Annual Report. These risks may include, but are not limited to, the following:
•
Our future business prospects depend heavily on our ability, with our collaborator Biogen, to successfully 
continue to commercialize ZURZUVAE for the treatment of women with PPD. We and Biogen may not be 
successful in our commercialization efforts for ZURZUVAE for the treatment of women with PPD. 
ZURZUVAE may not achieve, or, even if achieved, maintain, broad market acceptance. We may also 
encounter other limitations or issues related to the commercialization of ZURZUVAE, including as a result of 
its price or competition in the market. ZURZUVAE may not achieve brand awareness and adoption among 
healthcare professionals, including OBGYNs, and our beliefs about the potential for OBGYNs to utilize 
ZURZUAVE at the forefront of postpartum care may prove to be incorrect. As a result, we may not generate 
revenues at the levels or on the timing we expect. The number of women with PPD, the unmet need for 
additional treatment options, and the potential market for ZURZUVAE in this indication may be significantly 
smaller than we expect. Any setback or delay in our ability to market ZURZUVAE for the treatment of women 
with PPD may have a material adverse effect on our business and prospects. 
•
Our plans to explore strategic alternatives and our rejection of an unsolicited, non-binding acquisition proposal 
from Biogen to acquire all of our outstanding shares not owned by Biogen may have a material adverse effect 
on our business. Our rejection of the unsolicited, nonbinding acquisition proposal from Biogen, our efforts to 
enforce the terms of the stock purchase agreement we entered into with Biogen, and our strategic review 
process may adversely impact our relationship with Biogen, including our efforts to commercialize 
ZURZUVAE for the treatment of women with PPD. We cannot be certain that our efforts to date with Biogen, 
including regarding sales force coordination, engagement with payors, and education efforts related to PPD, 
will not be adversely impacted or that Biogen will continue to make investments related to ZURZUVAE. Any 
disruption of our relationship with Biogen under the Biogen collaboration agreement may have an adverse 
impact on sales of ZURZUVAE and may in turn materially adversely affect our business, results of operations, 
financial condition and prospects. We have not set a timetable for the strategic review process, nor have we 
made any decisions related to any potential strategic alternatives at this time. There can be no assurance that 
our strategic review process will result in any transaction or other strategic outcome. 
•
Our future business prospects also depend heavily on our ability to successfully develop and gain regulatory 
approval of our product candidates. We cannot be certain that the results of our development programs will be 
positive or sufficient to file for regulatory approval. Any setback or delay in obtaining regulatory approval for 
any of our product candidates or in our ability to commence marketing of our products, if approved, may have 
a material adverse effect on our business and prospects. 
•
If the affected populations for indications our products and product candidates are targeting, including the 
addressable markets within such populations, or the number of patients within such markets who are actually 
treated with our products, are smaller than we anticipate, or our other assumptions with respect to the potential 
markets for our products and product candidates are incorrect, our ability to achieve profits from the 
commercialization of such products, if approved, at the levels or on the timing we expect could be materially 
adversely impacted.
•
If serious adverse events or other undesirable side effects are identified during the use of any of our marketed 
products or product candidates, such events may adversely affect market acceptance or result in other 
significant negative consequences for an approved product; delay or prevent further development or regulatory 
approval with respect to product candidates; or cause regulatory authorities to require labeling statements, such 
as boxed warnings, or a Risk Evaluation and Mitigation Strategy, on approved products.
•
We, or our collaboration partners, may not achieve positive results in clinical trials and non-clinical studies of 
our product candidates. The results of non-clinical studies or clinical trials of our product candidates at any 
stage may not support further development or may not be sufficient to file for and obtain regulatory approval.
•
We may not generate revenues from our existing products, or any of our product candidates if successfully 
developed, at the levels we expect. We may not achieve events tied to cash milestone payments or other 
payments from our collaboration partners on the timelines we expect or at all. Our expenses may also be higher 
than we expect, including as a result of unexpected events or changes in plans. Also, we may not achieve 

anticipated cost savings from our October 2024 corporate reorganization at the levels we expect. As a result, 
our expectations as to our cash runway and the sufficiency of cash to fund our future operations may prove to 
be incorrect. We will need to raise additional funding, which may not be available on acceptable terms, or at 
all. 
•
Any impairment of the ability of our third-party suppliers to supply product or to meet applicable regulatory 
standards may significantly negatively impact our ability to achieve our goals and plans and to meet the 
expectations for our business.
•
Competing therapies may exist or could be approved that adversely affect the amount of revenue we are able to 
generate from the sale of ZURZUVAE for the treatment of women with PPD or any of our other current or 
future product candidates, if successfully developed and approved. 
•
Our existing collaborations with Biogen and Shionogi, and any future collaborations, may not lead to the 
successful development or regulatory approval of product candidates or commercialization of products in the 
territories covered by the applicable collaboration. Our collaborators may have competing priorities, 
conflicting incentives, or different views than us on key decisions, that may hamper or delay our development 
and commercialization efforts or increase our costs. Our business may be adversely affected and we may be 
subject to delays, disputes, or litigation if we disagree significantly with any of our collaborators, or any of our 
collaborators fails to perform its obligations or terminates our collaboration.
•
If we are unable to adequately protect our proprietary technology or obtain and maintain issued patents 
sufficient to protect our products or product candidates, others could compete against us more directly, which 
would have a material adverse impact on our business, results of operations, financial condition and prospects.
•
If we were to lose our rights to certain licensed intellectual property, or if we are not able to obtain licenses to 
intellectual property we may determine we need in the future, we may not be able to continue developing or 
commercializing certain of our products or product candidates, if approved.
•
Existing or future laws, regulations, executive orders or policies aimed at reducing healthcare costs may have a 
material adverse effect on our business or results of operations. Existing, pending or future federal and state 
reforms aimed at reducing healthcare costs, including pricing and reimbursement of pharmaceutical products, 
may in the future result in reduced reimbursement and access for our products or cause us to curtail certain 
development plans due to concerns about commercial viability, any of which could adversely affect our ability 
to generate revenue and negatively impact our business, results of operations and financial condition.
•
We are subject to healthcare laws and regulations, which could expose us to the risk of criminal sanctions, civil 
penalties, contractual damages, reputational harm and diminished profits and future earnings if we or our 
employees are alleged or determined not to have complied with such laws and regulations.
•
Our stock price may fluctuate in response to a number of factors.

Item 1. Business
Overview
We are a biopharmaceutical company with a mission to pioneer solutions to deliver life-changing brain health 
medicines, so every person can thrive. Alongside our commercial product for the treatment of postpartum depression, or 
PPD, we are advancing a portfolio of internally discovered novel chemical entities with the potential to become 
differentiated treatments designed to improve brain health by primarily targeting two critical central nervous system, or 
CNS, receptor systems, GABA and NMDA. The GABA receptor family, which is recognized as the major inhibitory 
neurotransmitter in the CNS, mediates downstream neurologic and bodily function via activation of GABAA receptors. 
The NMDA-type receptors of the glutamate receptor system are a major excitatory receptor system in the CNS. 
Dysfunction in these systems is thought to be at the core of numerous neuropsychiatric and neurodevelopmental disorders.
Our product ZURZUVAE® (zuranolone) was approved by the U.S. Food and Drug Administration, or FDA, in 
August 2023 for the treatment of PPD in adults. ZURZUVAE is a neuroactive steroid that is a positive allosteric 
modulator of GABAA receptors, targeting both synaptic and extrasynaptic GABAA receptors, and is the first oral, once-
daily, 14-day treatment specifically indicated for adults with PPD. ZURZUVAE became commercially available in the 
U.S. in December 2023 as a treatment option for women with PPD. We and our collaboration partner, Biogen MA Inc., or 
BIMA, and Biogen International GmbH, or, together with BIMA, Biogen, are jointly commercializing ZURZUVAE in 
the U.S. under our collaboration and license agreement, or the Biogen Collaboration Agreement, that became effective in 
December 2020. We and Biogen equally share in all operating profits and losses arising from sales of ZURZUVAE in the 
U.S., with Biogen recording such product sales. 
We jointly commercialize ZURZUVAE with Biogen in the U.S. and have the right to jointly commercialize any 
additional products containing zuranolone, which, along with ZURZUVAE, we refer to as Licensed 217 Products, if our 
ongoing and any future development efforts are successful. In addition, we have granted Biogen sole rights to develop and 
commercialize the Licensed 217 Products outside the U.S., other than in Japan, Taiwan and South Korea, or the Shionogi 
Territory, with respect to zuranolone, where we have granted such rights to Shionogi & Co., Ltd., or Shionogi. We refer to 
the territories outside the U.S. to which Biogen has rights under the Biogen Collaboration Agreement with respect to the 
Licensed 217 Products as the Biogen Territory.
We also have a collaboration agreement with Shionogi for the development of zuranolone in the Shionogi Territory. 
Shionogi is currently developing zuranolone for the treatment of patients with major depressive disorder, or MDD, in 
Japan. In the third quarter of 2024, Shionogi reported that it submitted a new drug application, or NDA, in Japan for 
zuranolone for the treatment of MDD.
We also previously commercialized ZULRESSO® (brexanolone) CIV injection for the treatment of 
PPD. ZULRESSO is approved in the U.S. for the treatment of PPD in individuals 15 years old and older. We launched 
ZULRESSO commercially in the U.S. in June 2019. ZULRESSO was administered as a continuous intravenous infusion 
for two and a half days and could only be administered in qualified medically-supervised healthcare settings. Given the 
complexities and challenges associated with administration of ZULRESSO, use of the product was limited and further 
reduced as a result of the availability of ZURZUVAE for the treatment of women with PPD. For that reason, we 
discontinued commercial availability of ZULRESSO in the U.S. as of December 31, 2024. 
We are also evaluating potential indications for SAGE-324, a novel GABAA receptor positive allosteric modulator 
intended for chronic oral dosing, including seizures in developmental and epileptic encephalopathies, or DEEs, and expect 
to provide an update on next steps, if any, in mid-2025.

8
Our other area of focus is SAGE-319, an extrasynaptic-preferring GABAA receptor positive allosteric modulator, or 
GABAA PAM, designed to have a novel pharmacology and a differentiated clinical profile from other GABAA PAMs in 
our portfolio. We are currently investigating SAGE-319 as a potential treatment for behavioral symptoms associated with 
certain neurodevelopmental disorders. We expect to announce data from a Phase 1 multiple ascending dose study by late 
2025, and will evaluate next steps, if any, based on these data.
We expect to continue to focus on the development of product candidates for the treatment of both acute and chronic 
brain health disorders, including work on allosteric modulation of the GABAA and NMDA receptor systems in the brain, 
and are continuing to explore targeted work within our NMDA receptor negative allosteric modulator, or NMDAR 
NAMs, platform, focusing on potential treatments for neurodevelopmental disorders, with SAGE-817 and SAGE-039. 
The GABAA and NMDA receptor systems are broadly accepted as impacting many neuropsychiatric and 
neurodevelopmental disorders, spanning disorders of mood, seizure, cognition, anxiety, sleep, pain, and movement, 
among others. We believe that we may have the opportunity to develop molecules from our internal portfolio with the 
goal of addressing a number of these disorders in the future, and also believe that we may have opportunity to use our 
scientific approach to explore targets beyond the GABAA and NMDA receptor systems and to develop compounds in 
areas of unmet need outside of brain health.
Our Strategy
Our goal is to build a top-tier biopharmaceutical company that is the leader in developing and commercializing life-
changing brain health medicines. Key elements of our strategy are to:

facilitating long-term growth. 
Understanding the Foundations of Our Approach
The CNS is composed of a vast and complex network of different structures and cell types, most of which serve, 
directly or indirectly, to provide a means for the nervous system to signal or communicate with other nerve cells to 
regulate brain function. The cell type responsible for this signaling is called a neuron. One way chemical or electrical 
signals exert their effects on neurons is by traveling across a physical gap located between two neurons, called a synapse. 
Presynaptic neurons transmit signals whereas postsynaptic neurons react to the signals. The human brain contains 
approximately 86 billion neurons, each having hundreds to tens of thousands of synapses to allow for this communication. 
This process is essential to all things, from organ function to movement, memory and all behavioral processes. 
Neurotransmission is the process by which signaling molecules, called neurotransmitters, are released by a presynaptic 
neuron, travel over the synaptic space and bind to and interact with receptors on a postsynaptic neuron. Depending on the 
nature of the neurotransmitter and receptor, this interaction results in excitation, inhibition or modulation of the receiving 
neuron’s behavior.
We are currently focused on developing drugs based on selective allosteric modulation of neurotransmitter receptors 
in the CNS. Allosteric modulators are a class of small molecules that interact at a site different from the site where 
neurotransmitters bind, and allow the potential for fine-tuning of neuronal signals. We believe that nowhere in the body is 
it more important to maintain normal rhythms than in the brain, and accordingly we believe that allosteric modulation 
approaches are well-suited for the treatment of diseases and disorders of the brain.
We utilize our proprietary chemistry capabilities to design and identify drug candidates that target critical CNS 
proteins and have properties aligned to the indications of interest. Our goal is to select for development compounds that 
we believe are capable of varying degrees of desired activity rather than complete activation or inhibition. 
Our focus as a company is on brain health, and we are currently primarily targeting two critical CNS receptor 
systems: GABA and NMDA. The GABA receptor family, which is recognized as the major inhibitory neurotransmitter in 
the CNS, mediates downstream neurologic and bodily function in part via activation of GABAA receptors. GABAA 
receptors play a key role in regulating neuron excitability. The NMDA-type receptors of the glutamate receptor system are 
a major excitatory receptor system in the CNS. NMDA receptors serve a critical role in CNS-related activities. 
Dysfunction in these systems is implicated in a broad range of brain disorders. 
Our proprietary chemistry platform is currently centered on our knowledge of the chemical scaffolds of endogenous 
neuroactive steroids. We have leveraged this platform to assemble a chemistry portfolio of greater than 15,000 
compounds. We believe our proprietary chemistry platform allows us to:
•
control important properties such as half-life, brain penetration and the types of receptors our drugs act upon, 
thereby modulating either inhibition or excitation either acutely or chronically; and
•
create drugs that are designed to exert control over the intensity of receptor activation or deactivation, with the 
potential to hit targets in the brain with more precision, with the goal of increased tolerability and fewer off-
target side effects than current CNS therapies or previous therapies that have failed in development. 
We target diseases and disorders of the brain where we believe patient populations are easily identified, clinical 
endpoints are well-defined, and development pathways are feasible.

Our Product Pipeline
The following table summarizes the status of our product and product candidate portfolio as of the filing date of this 
Annual Report.
ZURZUVAE (zuranolone)
Our product ZURZUVAE (zuranolone) was approved by the FDA in August 2023 for the treatment of PPD in 
adults. ZURZUVAE is a neuroactive steroid that is a positive allosteric modulator of GABAA receptors, targeting both 
synaptic and extrasynaptic GABAA receptors, and is the first oral, once-daily, 14-day treatment specifically indicated for 
adults with PPD. ZURZUVAE became commercially available in the U.S. for women with PPD in December 2023. We 
and our collaboration partner, Biogen, are jointly commercializing ZURZUVAE in the U.S. under the Biogen 
Collaboration Agreement. We and Biogen equally share in all operating profits and losses arising from sales of 
ZURZUVAE in the U.S., with Biogen recording such product sales. 
ZURZUVAE (zuranolone) received a Schedule IV classification from the Drug Enforcement Administration, or 
DEA. The approval of ZURZUVAE to treat PPD in adults was based on two pivotal clinical trials in adult women with 
PPD. ZURZUVAE includes a boxed warning that instructs healthcare professionals to advise patients that ZURZUVAE 
causes driving impairment due to central nervous system depressant effects, and that people who take ZURZUVAE 
should not drive a motor vehicle or engage in other potentially hazardous activities requiring complete mental alertness 
until at least 12 hours after ZURZUVAE administration for the duration of the 14-day treatment course. ZURZUVAE can 
cause CNS depressant effects. The most common side effects of ZURZUVAE include sleepiness or drowsiness, dizziness, 
common cold, diarrhea, feeling tired, weak, or having no energy, and urinary tract infection. 
PPD symptoms are some of the most common medical complications during and after pregnancy, and PPD is 
characterized by depressive symptoms that can begin during pregnancy or within the first 4 weeks to 12 months following 
childbirth. PPD symptoms may include sadness and depressed mood; anxiety or agitation; loss of interest in daily 
activities; changes in eating and sleeping habits; feeling overwhelmed; fatigue and decreased energy; inability to 
concentrate; hypervigilance about the baby or lack of interest in the baby; and feelings of worthlessness, shame or guilt. 
Based on our analysis of available data, we estimate that approximately 500,000 women in the U.S. each year may 

11
experience symptoms of PPD. PPD can lead to devastating consequences for a woman and for her family. In addition, the 
economic burden associated with perinatal depression can be vast and can impact patients, their families, employers, and 
healthcare payors.
ZURZUVAE is the first and only oral product approved by the FDA for women with PPD (and the second approved 
product for PPD after ZULRESSO). The current standard of care for PPD is comprised of psychotherapy and, in women 
with moderate or severe PPD, the cautious use of pharmacological therapies such as selective serotonin reuptake 
inhibitors, or SSRIs, and serotonin and norepinephrine reuptake inhibitors, or SNRIs.
Naturally occurring allopregnanolone is found at its highest levels in women during the third trimester of pregnancy, 
returning to normal levels generally within 24 hours after giving birth. Levels of allopregnanolone have been found to be 
lower in women with PPD than in healthy women. It may be that women with PPD are particularly sensitive to the rapid 
decline in allopregnanolone after birth, potentially causing GABAA-system mediated mood disruption. These data led to 
our interest in evaluating allosteric modulators of the GABAA receptor—such as brexanolone and zuranolone—for the 
treatment of PPD.
On August 4, 2023, the FDA issued a complete response letter, or CRL, related to the NDA for zuranolone for the 
treatment of MDD. The CRL stated that the NDA did not provide substantial evidence of effectiveness to support the 
approval of zuranolone for the treatment of MDD and that one or more additional clinical trials will be needed. We and 
Biogen have agreed not to pursue further development of zuranolone for the treatment of MDD in the U.S. This decision 
was based on the significant new investment and time we expect would be needed to conduct additional studies to support 
approval. We and Biogen plan to continue to collaborate on the commercialization of ZURZUVAE in PPD. 
We have granted Biogen sole rights to develop and commercialize zuranolone outside the U.S., other than in Japan, 
Taiwan and South Korea where we have granted rights to Shionogi. Shionogi is currently developing zuranolone for the 
treatment of patients with MDD in Japan.
SAGE-324 
Under the Biogen Collaboration Agreement, we and Biogen also previously agreed to jointly develop and 
commercialize products containing SAGE-324, which we refer to as the Licensed 324 Products. In July 2024, we and 
Biogen announced topline results from the KINETIC 2 Study, a Phase 2b dose-ranging clinical trial evaluating SAGE-
324, a novel GABAA receptor positive allosteric modulator intended for chronic oral dosing, in the treatment of patients 
with essential tremor. The KINETIC 2 Study did not demonstrate a statistically significant dose-response relationship in 
change from baseline to Day 91 based on the primary endpoint, the TETRAS PS Item 4 (upper limb) total score, in 
participants with essential tremor. In addition, there were no statistically significant differences demonstrated for any dose 
of SAGE-324 versus placebo in the change from baseline to Day 91 on the TETRAS PS Item 4 or the TETRAS Activities 
of Daily Living Composite Score. In the study, 147 participants (129 monotherapy and 18 adjunct therapy who were on a 
stable dose of propranolol prior to and during the study) were randomized in approximately equal proportions to placebo 
and each of the three formulations of SAGE-324—15 mg, 30 mg, and 60 mg (with up-titration)—for a three-month 
treatment period. Overall, there was a dose-relationship observed in the incidence of CNS depressant treatment emergent 
adverse events, or TEAEs, and in the frequency of TEAEs, leading to study drug discontinuation. The most common 
TEAEs reported in any treatment group were somnolence, dizziness, fatigue, feeling abnormal, headache, and balance 
disorder. The majority of reported TEAEs were mild or moderate in intensity. Given these results, we and Biogen decided 
to close the open-label Phase 2 clinical trial of SAGE-324 designed to evaluate the long-term safety and tolerability of 
SAGE-324 in patients with essential tremor and we do not plan to conduct further clinical development of SAGE-324 in 
essential tremor.
In September 2024, Biogen notified us of its termination of the Biogen Collaboration Agreement solely with respect 
to the Licensed 324 Products on a worldwide basis, effective February 17, 2025, or the SAGE-324 Termination. As a 
result of the SAGE-324 Termination, as of February 17, 2025, all licenses granted by us to Biogen or by Biogen to us 
regarding the Licensed 324 Products shall expire with respect to the Licensed 324 Products on a worldwide basis. Biogen 
shall grant to us an irrevocable, perpetual license for any Biogen background technology, Biogen collaboration technology 
or joint collaboration technology that exists as of February 17, 2025 with respect to the Licensed 324 Products on a 

12
worldwide basis, in each case in accordance with the terms of the Biogen Collaboration Agreement. We and Biogen 
continue to be responsible for our respective share of costs for ongoing activities related to the Licensed 324 Products in 
accordance with the terms of the Biogen Collaboration Agreement until February 17, 2025. 
We are evaluating other potential indications for SAGE-324, including seizures in DEEs, and expect to provide an 
update on next steps, if any, in mid-2025.
SAGE-319
SAGE-319 is an extrasynaptic-preferring GABAA PAM designed to have a novel pharmacology and a differentiated 
clinical profile from other GABAA PAMs in our portfolio. We are currently investigating SAGE-319 as a potential 
treatment for behavioral symptoms associated with certain neurodevelopmental disorders. We expect to announce data 
from a Phase 1 multiple ascending dose study by late 2025, and will evaluate next steps, if any, based on these data. 
Dalzanemdor (SAGE-718)
We previously evaluated dalzanemdor in certain cognitive disorders associated with NMDA receptor dysfunction. In 
November 2024, we announced that the DIMENSION Study, a Phase 2 clinical trial evaluating dalzanemdor for the 
treatment of patients with cognitive impairment associated with Huntington’s disease, did not demonstrate a statistically 
significant difference versus placebo on the primary endpoint, and analyses of secondary endpoints did not demonstrate 
statistically significant or clinically meaningful differences in participants treated with dalzanemdor compared to placebo. 
In addition, in October 2024, we announced that the LIGHTWAVE Study, a Phase 2 clinical trial evaluating dalzanemdor 
for the treatment of patients with mild cognitive impairment and mild dementia due to Alzheimer’s disease, did not meet 
its primary endpoint, and analyses did not demonstrate any meaningful differences versus placebo in the other exploratory 
endpoints. Previously, in April 2024, we announced that the PRECEDENT Study, a Phase 2 clinical trial evaluating 
dalzanemdor as a treatment for cognitive impairment due to Parkinson’s disease, did not meet its primary endpoint, and 
analyses did not suggest any meaningful differences versus placebo in the other exploratory endpoints. Based on these 
results, we do not plan to pursue further development of dalzanemdor.
Further Exploration of GABAA and NMDA Receptors and New Areas of Interest
We expect to continue to focus our research and development efforts on allosteric modulation of the GABAA and 
NMDA receptor systems in the brain, including targeted work within our NMDAR NAMs platform, focusing on potential 
treatments for neurodevelopmental disorders, with SAGE-817 and SAGE-039. The GABAA and NMDA receptor systems 
are broadly accepted as impacting many neuropsychiatric and neurodevelopmental disorders, spanning disorders of mood, 
seizure, cognition, anxiety, sleep, pain, and movement among others. We believe that we may have opportunities to 
develop molecules from our internal portfolio to address a number of these disorders in the future. Our ability to identify 
and develop such novel brain health therapies is enabled by our proprietary chemistry platform that is centered, as a 
starting point, on knowledge of the chemical scaffolds of certain endogenous neuroactive steroid compounds. We believe 
our knowledge of the chemistry and activity of allosteric modulators allows us to efficiently design molecules with 
different characteristics. This diversity enables us to regulate important properties such as half-life, brain penetration and 
receptor pharmacology to develop product candidates that have the potential for better selectivity, increased tolerability, 
and fewer off-target side effects than either current therapies or previous therapies which have failed in development.
We believe our ability to design and develop novel molecules with distinct profiles and receptor subtype selectivity 
may also provide us with the option, if we choose, to potentially partner certain assets with third parties who possess the 
development and commercialization capabilities to pursue these programs. We may also evaluate opportunities to acquire 
new compounds, product candidates or products from other companies or from academic institutions if we believe such 
opportunities will help us achieve our goals or meet other strategic objectives.

13
Manufacturing and Supply
We neither own nor operate, and currently have no plans to own or operate, any manufacturing facilities. We 
currently source all of our clinical and non-clinical material supply through third-party contract manufacturing 
organizations, or CMOs. We rely on our contract manufacturers to manufacture sufficient quantities of ZURZUVAE 
active drug substance, finished drug product and packaged and labeled product. We also previously relied on our contract 
manufacturers for commercial supplies of active drug substance, finished drug product and packaged and labeled product 
with respect to ZULRESSO until we discontinued ZULRESSO commercial availability in the U.S. as of December 31, 
2024. We intend to source all of our future commercial supplies of ZURZUVAE and our product candidates, if approved 
by the FDA, from CMOs.
We have a long-term supply agreement with our contract manufacturer for ZURZUVAE drug product. We have an 
inventory of ZURZUVAE drug substance and drug product in place to help mitigate any potential supply risks. All 
commercial supplies are intended to be manufactured applying current Good Manufacturing Practices, or cGMP.
We have established relationships with CMOs under which the CMOs manufacture clinical and non-clinical supplies 
of drug substance and drug product for our product candidates on a purchase order basis under master service and quality 
agreements. All clinical supplies of drug substance and drug product are intended to be manufactured under cGMP. 
Starting materials and key intermediates to support the production of these product candidates are manufactured by other 
CMOs. We do not currently have arrangements in place for either long-term supply or redundant supply of drug substance 
or drug product for any of our product candidates. We intend to put long-term supply agreements in place at the 
appropriate time for drug substance and drug product for our product candidates, if development continues. We plan to 
mitigate potential commercial supply risks for any products that are approved in the future through inventory management 
and through exploring additional manufacturers to provide drug substance or drug product. We also intend to improve the 
manufacturing process for our product candidates and manufacture clinical supplies as development progresses. 
ZURZUVAE, SAGE-319, and SAGE-324 are small molecules isolated as stable crystalline solids. We believe the 
syntheses of ZURZUVAE, SAGE-319, and SAGE-324 are reliable and reproducible from readily available starting 
materials, and the synthetic routes are amenable to large-scale manufacturing and do not require unusual equipment in the 
manufacturing process. We expect to continue to identify and develop drug candidates that are amenable to cost-effective 
manufacturing at contract manufacturing facilities. 
Sales and Marketing 
Our product ZURZUVAE became commercially available in the U.S. in December 2023 as the first and only oral 
product approved by the FDA specifically for the treatment of adults with PPD. We and Biogen are jointly 
commercializing ZURZUVAE in the U.S. for the treatment of women with PPD under the Biogen Collaboration 
Agreement. We and Biogen equally share in all operating profits and losses arising from sales of ZURZUVAE in the U.S., 
with Biogen recording such sales.
We and Biogen are utilizing a specialty pharmacy distribution model by which ZURZUVAE is shipped directly to 
women with PPD who are prescribed the treatment. We and Biogen have active field sales forces supported by 
experienced sales leadership teams and professionals in marketing, access and reimbursement, managed markets, market 
research, commercial operations, and sales force planning and management. We and Biogen are continuing to engage in 
discussions with national, regional and government payors to advocate for broad and equitable access to ZURZUVAE for 
women with PPD with minimal restrictions. Payor coverage for ZURZUVAE for the treatment of women with PPD is 
currently in place for a majority of commercial and Medicaid covered lives without step therapy or complex prior 
authorizations, including coverage from all three national Pharmacy Benefit Managers. We expect formulary discussions 
to continue over the course of 2025. 
We and Biogen are focused on helping women with PPD by optimizing access to ZURZUVAE, increasing 
education and awareness, driving urgency to treat women with PPD, and breaking the stigma associated with PPD. To 
accomplish these objectives, we are utilizing a broad omnichannel approach that includes both personal and non-personal 
promotion. Through Sage and Biogen’s sales forces, we are engaging in promotional dialogues with healthcare 
professionals who diagnose and treat women with PPD. These efforts are supplemented by dynamic digital tools that 

14
provide education about PPD to a broader range of healthcare professionals, patients, and patient advocates. Over the 
course of 2024, we saw prescribing across healthcare professional specialties, with OBGYNs comprising the primary 
prescriber group. This is notable, as we believe OBGYNs are at the forefront of postpartum care for so many women with 
PPD given the role they play in a woman’s peripartum journey.
To help enable broad and equitable access, we also maintain a patient support program, ZURZUVAE For You, 
which provides educational resources, help with understanding insurance coverage, and assistance navigating the 
prescription fulfillment process for women with PPD who are prescribed treatment. This program also includes financial 
assistance for women with PPD, such as the potential for copay assistance for those with commercial insurance and the 
potential to be provided product at no cost for other eligible patients.
We and Biogen are also working to help raise awareness of the importance of treating PPD rapidly and removing 
barriers to treatment. Our commercialization infrastructure also includes capabilities in medical affairs, manufacturing, 
quality control, drug safety and pharmacovigilance, health economics and outcomes research (HEOR), and compliance.
In addition to our joint commercialization of ZURZUVAE for the treatment of women with PPD in the U.S., the 
Biogen Collaboration Agreement provides that we will jointly commercialize in the U.S. other Licensed 217 Products if 
pursued and successfully developed and approved, including sharing equally in sales and marketing activities and profits 
and losses in the U.S. We have granted Biogen sole rights to commercialize the Licensed 217 Products in the Biogen 
Territory.
Licenses 
We have entered into license agreements with respect to our product and clinical-stage product candidates, which are 
described below.
Collaboration and License Agreement with Biogen 
In November 2020, we entered into the Biogen Collaboration Agreement with Biogen for the development, 
manufacture and commercialization of Licensed 217 Products and Licensed 324 Products (each, a “Product Class”), 
which became effective in December 2020. As a result of the SAGE-324 Termination, as of February 17, 2025, all 
licenses granted by us to Biogen or by Biogen to us regarding the Licensed 324 Products shall expire with respect to the 
Licensed 324 Products on a worldwide basis. Biogen shall grant to us an irrevocable, perpetual license for any Biogen 
background technology, Biogen collaboration technology or joint collaboration technology that exists as of February 17, 
2025 with respect to the Licensed 324 Products on a worldwide basis, in each case in accordance with the terms of the 
Biogen Collaboration Agreement. We and Biogen continue to be responsible for our respective share of costs for ongoing 
activities related to the Licensed 324 Products in accordance with the terms of the Biogen Collaboration Agreement until 
February 17, 2025.
Under the Biogen Collaboration Agreement, after the effectiveness of the SAGE-324 termination, we and Biogen 
agreed that we will jointly develop and commercialize the Licensed 217 Products in the U.S., and that Biogen solely will 
develop and commercialize the Licensed 217 Products in the Biogen Territory. We and Biogen have agreed to share 
jointly in the performance of the activities under the Biogen Collaboration Agreement in the U.S. and to share all 
operating profits and losses for activities under the Biogen Collaboration Agreement solely for the U.S. equally. The 
Biogen Collaboration Agreement provides that Biogen has sole responsibility and decision-making authority with respect 
to such activities in the Biogen Territory. Biogen is solely responsible for all costs for activities under the Biogen 
Collaboration Agreement in the Biogen Territory. We have an Opt-Out Right (as defined below) in the U.S. with respect 
to the Licensed 217 Products.
We have granted to Biogen a non-transferable, sublicensable, except for certain specified exceptions, license to 
certain of our intellectual property as needed to perform the activities under the Biogen Collaboration Agreement. Such 
license is co-exclusive with us in the U.S. and exclusive, even as to us, in the Biogen Territory, subject to certain retained 
rights to allow us to exercise our rights and perform our obligations under the Agreement and with respect to the Shionogi 
Territory.

15
Our activities for the Licensed 217 Products in the U.S. are conducted pursuant to joint plans agreed to by us and 
Biogen, and overseen by a joint steering committee, or the JSC. The JSC is composed of an equal number of 
representatives from each of us and Biogen.
Under the terms of the Biogen Collaboration Agreement, Biogen paid us an upfront payment of $875.0 million on 
December 31, 2020. For so long as a Licensed 217 Product is being sold in the U.S., we and Biogen will share equally in 
all operating profits and losses arising from such Licensed 217 Product in the U.S. The Biogen Collaboration Agreement 
provides that Biogen will record sales of Licensed 217 Products globally. Consistent with this provision, Biogen records 
sales of ZURZUVAE in the U.S. We have the right to opt out of such profit- and loss-sharing with respect to the Licensed 
217 Products in the U.S., or an Opt-Out Right. If we elect to exercise our Opt-Out Right with respect to the Licensed 217 
Products, we have agreed to transition to Biogen applicable development and commercialization activities for such 
Licensed 217 Products for the U.S., and Biogen has agreed to assume sole operational and financial responsibility for such 
activities.
The Biogen Collaboration Agreement provides for aggregate regulatory/commercial milestone payments from 
Biogen to us for Licensed 217 Products of up to $475.0 million, including milestones totaling $75.0 million for the first 
commercial sale of ZURZUVAE for the treatment of women with PPD in the U.S. and $150.0 million for the first 
commercial sale of zuranolone in MDD in the U.S., if approved. It also provides for aggregate one-time sales milestone 
payments from Biogen to us of (i) up to $300.0 million for Licensed 217 Products if we have not exercised our Opt-Out 
Right with respect to such Licensed 217 Products and (ii) up to $525.0 million for Licensed 217 Products if we have 
exercised our Opt-Out Right with respect to such Licensed 217 Products. We achieved the milestone totaling $75.0 
million for the first commercial sale of ZURZUVAE for the treatment of women with PPD in the U.S. in the fourth 
quarter of 2023, as a result of the first sale of ZURZUVAE to a distributor, and received the milestone payment in January 
2024. Because we and Biogen have agreed not to pursue further development for zuranolone for the treatment of MDD in 
the U.S., we will not receive the $150.0 million milestone payment for the first commercial sale of ZURZUVAE for the 
treatment of MDD in the U.S.
Biogen has also agreed to pay us tiered royalties based on net sales of the Licensed 217 Products in the Biogen 
Territory of high-teens to low-twenties percentages. If we have exercised our Opt-Out Right in the U.S. with respect to 
Licensed 217 Products, Biogen has agreed to pay us specified royalties based on net sales of Licensed 217 Products. 
Royalty payments may be reduced in certain specified customary circumstances. Due to the uncertainty of pharmaceutical 
development and the high historical failure rates generally associated with drug development, we may never receive 
additional milestone payments or any royalty payments from Biogen.
During the term of the Biogen Collaboration Agreement, neither us nor Biogen nor any of our respective affiliates is 
permitted outside of the Biogen Collaboration Agreement to directly or indirectly develop, manufacture, conduct medical 
affairs activities or commercialize certain products in specified indications, or enter into agreements or arrangements with 
third parties to perform any of the above activities.
Unless earlier terminated, the Biogen Collaboration Agreement expires on a Licensed Product-by-Licensed Product 
and country-by-country basis on the later of (i) in the Biogen Territory, the expiration of the royalty term for such 
Licensed Product in such country or (ii) in the U.S., until the parties agree to permanently stop commercializing such 
Licensed Product. Biogen may terminate the Biogen Collaboration Agreement for convenience in its entirety or on a 
Product Class-by-Product Class basis, as it did with the SAGE-324 Termination, or as to a region by providing advance 
written notice. Either us or Biogen may terminate the Biogen Collaboration Agreement (i) in the event of a material 
breach in whole or in part, by the other party subject to a cure period and (ii) in the event of the insolvency of the other 
party, in each case subject to specified conditions.
In connection with the execution of the Biogen Collaboration Agreement, we and BIMA also entered into a stock 
purchase agreement, or the Biogen Stock Purchase Agreement, for the sale and issuance of 6,241,473 shares of our 
common stock, or the Biogen Shares, to BIMA at a price of approximately $104.14 per share, a premium of 40% over the 
volume-weighted average share price for the 30 days ending on the day prior to entry into the Biogen Stock Purchase 
Agreement, for an aggregate purchase price of $650.0 million. The sale of the Biogen Shares was consummated on 
December 31, 2020. 

16
We have granted BIMA specified demand and piggyback registration rights with respect to the Biogen Shares. The 
Biogen Stock Purchase Agreement also includes standstill provisions and a voting agreement with respect to the Biogen 
Shares. Pursuant to the terms of the Biogen Stock Purchase Agreement, BIMA has agreed not to, and to cause its affiliates 
not to, directly or indirectly acquire our securities, seek or propose a tender or exchange offer or merger between us and 
BIMA, solicit proxies or consents with respect to any matter, or undertake other specified actions, in each case subject to 
specified conditions. The standstill restrictions terminate on the earliest of (i) a specified period of time after a regulatory 
milestone under the Biogen Collaboration Agreement, (ii) the date one year following the termination of the Biogen 
Collaboration Agreement and (iii) December 28, 2027.
For additional information related to the Biogen Collaboration Agreement, see the Risk Factor captioned “Our plans 
to explore strategic alternatives and our rejection of an unsolicited, non-binding acquisition proposal from Biogen to 
acquire all of our outstanding shares not owned by Biogen may have a material adverse effect on our business” under 
Part I, Item 1A, “Risk Factors” of this Annual Report.
Collaboration Agreement with Shionogi & Co., Ltd.
In June 2018, we entered into a collaboration agreement with Shionogi. Pursuant to this agreement, Shionogi is 
responsible for all clinical development, regulatory filings and commercialization of products containing zuranolone for 
the treatment of MDD and potentially other indications in the Shionogi Territory. Shionogi made an upfront payment of 
$90.0 million in 2018, and we will be eligible to receive additional payments of up to $485.0 million if certain regulatory 
and commercial milestones are achieved by Shionogi.
Under the terms of the agreement, the potential future milestone payments include up to $70.0 million for the 
achievement of specified regulatory milestones, up to $30.0 million for the achievement of specified commercialization 
milestones, and up to $385.0 million for the achievement of specified net sales milestones. The potential future milestone 
payments for achievement of specified regulatory milestones was reduced to $55.0 million upon failure to received FDA 
approval of zuranolone for the treatment of MDD in the U.S. prior to December 31, 2023. We will receive tiered royalties 
on sales of zuranolone in the Shionogi Territory, if development efforts are successful, with tiers averaging in the low to 
mid-twenty percent range, subject to other terms of the agreement. Due to the uncertainty of pharmaceutical development 
and the high historical failure rates generally associated with drug development, we may not receive any additional 
milestone payments or any royalty payments from Shionogi.
As between us and Shionogi, we maintain exclusive rights to develop and commercialize zuranolone outside of the 
Shionogi Territory. The upfront cash payment and any payments for milestones and royalties are non-refundable and non-
creditable.
The agreement with Shionogi will terminate on a licensed product-by-licensed product basis on the date on which 
the royalty term has expired in each country in the Shionogi Territory for such licensed product and will ultimately expire 
upon the expiration of the last-to-expire royalty term. Shionogi may remove South Korea or Taiwan from the covered 
territories, for any reason or no reason upon 180 days’ prior written notice. Shionogi may terminate the agreement in its 
entirety for any reason or no reason upon 180 days’ prior written notice. Shionogi may also terminate the agreement in the 
event of a serious adverse event or a clinical failure upon 60 days’ written notice to us. Either party may terminate this 
agreement early in the event of an uncured material breach within 180 days’ after notice is delivered to the other party. 
Intellectual Property
We strive to protect the proprietary know-how and technology that we believe is important to our business, 
including seeking and maintaining patents intended to cover our product candidates and compositions, their methods of 
use and processes for their manufacture, and any other aspects of inventions that are commercially important to the 
development of our business. We may 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. To protect our rights to our proprietary know-how and 
technology, we require all employees, as well as our consultants and contract research organizations, or CROs, when 
feasible, to enter into agreements that generally require disclosure and assignment to us of ideas, developments, 
discoveries and inventions made by these employees, consultants, and CROs in the course of their service to us.

17
We plan to continue to expand our intellectual property estate by filing patent applications directed to compositions, 
methods of use, treatment and patient selection, formulations and manufacturing processes created or identified from our 
ongoing development of our product candidates. Our success will depend on our ability to obtain and maintain patent and 
other proprietary protection for commercially important technology, inventions and know-how related to our business; 
defend and enforce our patents; preserve the confidentiality of our trade secrets; and operate without infringing the valid 
and enforceable patents and proprietary rights of third parties. We also rely on know-how and continuing technological 
innovation and may pursue in-licensing opportunities to develop and maintain our proprietary position. We seek to obtain 
domestic and international patent protection, and endeavor to promptly file patent applications for new commercially 
valuable inventions.
The patent positions of biopharmaceutical companies like us are generally uncertain and involve complex legal, 
scientific and factual questions. In addition, the coverage claimed in a patent application can be significantly reduced 
before the patent is issued, and patent scope can be reinterpreted by the courts after issuance. Moreover, many 
jurisdictions, including the U.S., permit third parties to challenge issued patents in administrative proceedings, which may 
result in further narrowing or even cancellation of patent claims. We cannot predict whether the patent applications we are 
currently pursuing, or may in the future pursue, will issue as patents in any particular jurisdiction or whether the claims of 
any issued patents will be enforceable or provide sufficient protection from competitors.
Because patent applications in the U.S. and certain other jurisdictions are maintained in secrecy for 18 months or 
potentially even longer, and since publication of discoveries in the scientific or patent literature often lags behind actual 
discoveries, we cannot be certain of the priority of inventions covered by our issued patents, our pending patent 
applications or of patent applications we may file in the future. Moreover, we may have to participate in interference 
proceedings or derivation proceedings declared by the U.S. Patent and Trademark Office, or U.S. PTO, or similar 
proceedings outside the U.S., to determine priority of invention.
Patents
We hold issued patents and pending patent applications in the U.S., and in certain foreign countries. Our intellectual 
property holdings include, but are not limited to:
•
One issued U.S. patent, exclusively licensed to us, covering a method of using our proprietary brexanolone 
formulation to treat PPD, which will expire in 2033; one U.S. issued patent and one granted patent in Europe 
covering our proprietary formulation of brexanolone, which will expire in 2033; and one U.S. issued patent 
covering the dosage regimen of brexanolone to treat PPD, which will expire in 2037;
•
Pending U.S. and foreign patent applications covering certain aspects of brexanolone, including courses of 
treatment, dosage regimens, methods for manufacturing, and additional uses of the formulation of brexanolone 
to treat various brain health diseases and disorders, including PPD;
•
One issued U.S. patent covering the composition of matter of zuranolone, three issued U.S. patents covering 
methods of using zuranolone, one granted European patent covering the composition of matter of zuranolone,

subject to any potential extensions; one issued U.S. patent covering certain solid forms of zuranolone, and one 
issued U.S. patent covering methods of using certain solid forms of zuranolone, each of which expires in 
August 2037, subject to any potential extensions; and pending U.S. and foreign patent applications covering 
zuranolone, uses of zuranolone to treat various brain health diseases and disorders, and solid forms of 
zuranolone;
•
Issued patents covering the composition of matter for SAGE-324 in Europe and Japan, expiring in May 2035, 
subject to any potential extensions, and U.S. and foreign patent applications covering SAGE-324, SAGE-319, 
and many other modulators of the GABAA receptor and uses of these compounds to treat various brain health 
diseases and disorders;
•
Two issued U.S. patents covering composition of matter and method of use of SAGE-689 which expire in 
December 2033, subject to any potential extensions, and U.S. and foreign patent applications covering SAGE-
689 and uses of SAGE-689 to treat various brain health diseases and disorders. These patents and patent 
applications are co-owned with Washington University, and Sage has an exclusive license to Washington 
University’s rights in these patents and patent applications; and 

18
•
U.S. and foreign patents and patent applications covering modulators of the NMDA receptor, and uses of these 
compounds to treat various brain health diseases and disorders. 
Patent Term
The base term of a U.S. patent is 20 years from the filing date of the earliest-filed non-provisional patent application 
from which the patent claims priority. The term of a U.S. patent can be lengthened by patent term adjustment, which 
compensates the owner of the patent for administrative delays at the U.S. PTO. In some cases, the term of a U.S. patent, 
including any accrued patent term adjustment, is shortened by terminal disclaimer that reduces its term to that of an 
earlier-expiring patent.
The term of a U.S. patent may also be eligible for patent term extension under the Drug Price Competition and 
Patent Term Restoration Act of 1984, referred to as the Hatch-Waxman Act, to account for at least some of the time the 
drug is under development and regulatory review after the patent is granted. With regard to a drug for which FDA 
approval is the first permitted marketing of the active ingredient, the Hatch-Waxman Act allows for extension of the term 
of one U.S. patent that includes at least one claim covering the composition of matter of an FDA-approved drug, an FDA-
approved method of treatment using the drug, and/or a method of manufacturing the FDA-approved drug. The extended 
patent term cannot exceed the shorter of five years beyond the non-extended expiration of the patent or 14 years from the 
date of the FDA approval of the drug. Some foreign jurisdictions, including Europe and Japan, also have patent term 
extension provisions, which allow for extension of the term of a patent that covers a drug approved by the applicable 
foreign regulatory agency. In the future, if and when our pharmaceutical products receive FDA approval, we expect to 
apply for patent term extension on patents covering those products, their methods of use, and/or methods of manufacture.
Trade Secrets
In addition to patents, we may rely on trade secrets and know-how to develop and maintain our competitive position. 
Companies typically rely on trade secrets to protect aspects of their business that are not amenable to, or that they do not 
consider appropriate for, patent protection. We protect trade secrets, if any, and know-how by establishing confidentiality 
agreements and invention assignment agreements with our employees, and, where feasible, with consultants, scientific 
advisors, contractors and certain other entities with whom we do business. These agreements generally provide that all 
confidential information developed or made known during the course of an individual or entity’s relationship with us must 
be kept confidential during and after the relationship. These agreements also generally provide that all relevant inventions 
resulting from work performed for us or relating to our business and conceived or completed during the period of 
employment or assignment, as applicable, shall be our exclusive property. In addition, we take other appropriate 
precautions, such as physical and technological security measures, designed to guard against misappropriation of our 
proprietary information by third parties.
Competition
The biopharmaceuticals industry is highly competitive. There are many public and private companies, universities, 
governmental agencies and other research organizations actively engaged in the research and development of products 
that may be similar to our product or product candidates or address similar markets. It is probable that the number of 
companies seeking to develop products and therapies similar to our products or targeting similar indications will increase.
Currently, the only pharmacological therapies specifically approved for the treatment of PPD are ZURZUVAE and 
ZULRESSO. We discontinued commercial availability of ZULRESSO in the U.S. as of December 31, 2024. 
ZURZUVAE currently competes with the current standard of care for PPD, which commonly consists of psychotherapy; 
however, patients with moderate or severe PPD are often prescribed antidepressant medications such as SSRIs and SNRIs. 
ZURZUVAE may also face competition from drugs currently in development, if successfully developed and approved in 
the future for the treatment of PPD, including potentially LPCN 1154, an oral formulation of the neuroactive steroid 
brexanolone under development by Lipocine, Inc. under the streamlined 505(b)(2) regulatory pathway, which allows for 
approval of an abbreviated NDA by the FDA, and BRII-296, an intramuscular formulation of brexanolone being 
developed by Brii Biosciences.  
In the field of neuroactive steroids focused specifically on modulation of GABAA receptors, we also face 
competition from a number of companies, including Marinus Pharmaceuticals, Inc. (acquired by Immedica Pharma AB), 

19
which received FDA approval of ganaxolone, a known GABAA positive allosteric modulator neuroactive steroid, to treat 
seizures associated with CDKL5 deficiency disorder, a rare, genetic epilepsy. Other GABAA competitors include 
darigabat, which is being developed by Cerevel Therapeutics, Inc. (acquired by AbbVie Inc.) for the treatment of epilepsy 
and panic disorder.
Many of our potential competitors, alone or with their strategic partners, have substantially greater financial, 
technical and human resources than we do, and significantly greater experience in the discovery and development of 
product candidates, obtaining FDA and other regulatory approvals of treatments and the commercialization of those 
treatments. Mergers and acquisitions in the biotechnology and pharmaceutical industries may result in even more 
resources being concentrated among a smaller number of our competitors. We expect competition in the indications we 
are pursuing will focus on efficacy, safety, convenience, availability, and price. Our commercial opportunity could be 
reduced or eliminated if our competitors develop and commercialize products that are perceived to be safer, more 
effective, have fewer or less severe side effects, are more convenient or are less expensive than any 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, which could result in our competitors establishing a strong market position before we are able to 
enter the market.
Government Regulation 
Government authorities in the U.S. at the federal, state and local level and in other countries extensively regulate, 
among other things, the research, development, testing, manufacture, quality control, approval, labeling, packaging, 
storage, record-keeping, promotion, advertising, distribution, post-approval monitoring/pharmacovigilance, safety and 
periodic reporting, marketing and export and import of drug products. Generally, before a new drug can be marketed in a 
given jurisdiction, considerable data demonstrating its quality, safety and efficacy must be obtained and/or generated, 
organized into a format specific to each regulatory authority, submitted for review and the drug must be approved by the 
relevant regulatory authority or authorities.
U.S. Drug Development
In the U.S., the FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act, or FDCA, and its 
implementing regulations. Drugs are also subject to other federal, state and local statutes and regulations. The process of 
obtaining regulatory approvals and the subsequent compliance with appropriate federal, state, and local statutes and 
regulations require 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 a 
company to administrative or judicial sanctions. These sanctions could include, among other actions, the FDA’s delay or 
refusal to approve pending applications, withdrawal of an approval, a clinical hold on a clinical investigation, warning or 
untitled letters, product recalls or withdrawals from the market, product seizures, total or partial suspension of production 
or distribution, injunctions, fines, refusals of government contracts, restitution, disgorgement, or civil penalties or criminal 
prosecution. Any agency or judicial enforcement action could have a material adverse effect on us.
Our product candidates must be approved by the FDA through the NDA process before they may be legally 
marketed in the U.S. The process required by the FDA before a drug may be marketed in the U.S. requires substantial 
time, effort and financial resources and generally involves the following:
•
Completion of extensive non-clinical studies and testing, including non-clinical laboratory tests, animal studies 
and formulation studies, in accordance with applicable regulations, including the FDA’s current Good 
Laboratory Practice, or GLP, regulations;
•
Submission to the FDA of an Investigational New Drug, or IND, application, which must become effective 
before human clinical trials may begin;
•
Approval by an independent institutional review board, or IRB, or ethics committee representing each clinical 
trial site before each trial may be initiated;

20
•
Performance of adequate and well-controlled human clinical trials in accordance with applicable IND and 
other clinical trial-related regulations, sometimes collectively referred to as good clinical practice, or GCP, to 
establish the safety and efficacy of the proposed drug for each proposed indication;
•
Submission to the FDA of an NDA for marketing approval of the new drug;
•
Determination by the FDA within 60 days of its receipt of an NDA to accept and file the NDA for review;
•
Satisfactory completion of a potential FDA pre-approval inspection of the manufacturing facility or facilities 
where the drug is produced to assess compliance with cGMP requirements to assure that the facilities, methods 
and controls are adequate to preserve the drug’s identity, strength, quality and purity;
•
Potential FDA audit of the non-clinical and/or clinical trial sites that generated the data in support of the NDA; 
and
•
Payment of applicable user fees and FDA review and approval of the NDA, including consideration of the 
views of any FDA advisory committee and scheduling by the DEA, if applicable, prior to any commercial 
marketing or sale of the drug in the U.S.
The data required to support an NDA are generated in two distinct development stages: non-clinical and clinical. For 
new chemical entities, the non-clinical development stage generally involves synthesizing the active component, 
developing the formulation and determining the manufacturing process, as well as carrying out non-human toxicology, 
pharmacology and drug metabolism studies in the laboratory, which are typically intended to support subsequent clinical 
testing. Non-clinical tests include laboratory evaluations of product chemistry, formulation, stability and toxicity, as well 
as animal studies to assess the characteristics and potential safety and efficacy of the product. The conduct of the non-
clinical tests must comply with federal laws and regulations, including, for animal studies, the Animal Welfare Act and 
GLPs. The sponsor must submit the results of the non-clinical tests, together with manufacturing information, analytical 
data, any available clinical data or literature and a proposed clinical protocol, to the FDA as part of the IND. These studies 
are typically referred to as IND-enabling studies.
An IND is a request for authorization from the FDA to administer an investigational drug product to humans in the 
context of a clinical study. An IND must become effective before human clinical trials may begin. The central focus of an 
IND submission is on the general investigational plan and the protocols for human trials. The IND automatically becomes 
effective 30 days after receipt by the FDA, unless the FDA raises concerns or questions regarding the proposed clinical 
trials, including whether subjects will be exposed to unreasonable health risks, and places the IND on clinical hold within 
that 30-day time period. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the 
clinical trial can begin. The FDA may also impose clinical holds on a drug candidate at any time before or during clinical 
trials due to safety concerns or non-compliance. Accordingly, we cannot be sure that submission of an IND will result in 
the FDA allowing clinical trials to begin, or that, once begun, issues will not arise that could cause the trial to be 
suspended or terminated.
The clinical stage of development generally involves the administration of the drug candidate to healthy volunteers 
and then to patients with the disease or condition being studied under the supervision of qualified investigators, which 
generally are physicians not employed by or under the trial sponsor’s control. Clinical trials must be conducted in 
accordance with GCPs, which establish standards for conducting, recording data from, and reporting the results of, 
clinical trials, and are intended to assure that the data and reported results are credible and accurate, and that the rights, 
safety, and well-being of study participants are protected. GCPs include the requirement that all research subjects provide 
their informed consent for their participation in any given clinical trial. Clinical trials are conducted under protocols 
describing, among other details, the objectives of the clinical trial, dosing procedures, subject selection and exclusion 
criteria, and the parameters to be used to monitor subject safety and assess efficacy. Each protocol, and any subsequent 
amendments to the protocol, must be submitted to the FDA as part of the IND. Further, each clinical trial must be 
reviewed and approved by an IRB at or servicing each institution at which the clinical trial will be conducted. An IRB is 
charged with protecting the welfare and rights of trial participants, and considers such items as whether the risks to 
individuals participating in the clinical trials are minimized and are reasonable in relation to anticipated benefits. The IRB 
also approves the informed consent form that must be provided to each clinical trial subject or his or her legal 
representative and monitors the clinical trial until completed. Companies sponsoring the clinical trials, investigators, and 

21
IRBs also must comply with, as applicable, regulations and guidelines for obtaining informed consent from the study 
patients, following the protocol and investigational plan, adequately monitoring the clinical trial, and timely reporting of 
adverse events. There are also requirements governing the reporting of ongoing clinical trials and completed clinical trial 
results to public registries.
A sponsor who wishes to conduct a clinical trial outside the U.S. may, but need not, obtain FDA authorization to 
conduct the clinical trial under an IND. Foreign studies conducted under an IND must meet the same requirements that 
apply to studies being conducted in the U.S. If a foreign clinical trial is not conducted under an IND, the FDA will accept 
the study as support for an NDA so long as the clinical trial is well-designed and well-conducted, conducted in 
compliance with GCPs, including review and approval by an independent ethics committee and compliance with informed 
consent principles, and the FDA is able to validate the data from the study through an onsite inspection if deemed 
necessary.
Clinical Trials
Clinical trials are generally conducted in three phases that may overlap, known as Phase 1, Phase 2 and Phase 3 
clinical trials.
•
Phase 1 clinical trials generally involve a small number of healthy volunteers who are initially exposed to a 
single dose and then multiple doses of the product candidate. The primary purpose of these clinical trials is to 
assess the metabolism, pharmacologic action, side effect tolerability and the early safety profile of the drug.
•
Phase 2 clinical trials typically involve studies in patients afflicted with the target disease to determine the dose 
required to produce the desired benefits. At the same time, safety and further pharmacokinetic and 
pharmacodynamic information is collected, as well as identification of possible adverse effects and safety risks 
and preliminary evaluation of efficacy.
•
Phase 3 clinical trials generally involve large numbers of patients afflicted with the target disease at multiple 
sites (typically from several hundred to several thousand subjects), and are designed to provide the data 
necessary to demonstrate the effectiveness of the product for its intended use, its safety in use, and to establish 
the overall benefit/risk relationship of the product and provide an adequate basis for product approval and 
labeling. Phase 3 clinical trials may include comparisons with placebo and/or other comparator treatments. The 
duration of treatment is often extended for drugs intended for chronic dosing to mimic the actual use of a 
product during marketing.
Post-approval trials, sometimes referred to as Phase 4 clinical trials, may be conducted after initial marketing 
approval. These trials are used to gain additional information from the treatment of patients in the intended therapeutic 
indication. In certain instances, the FDA may mandate the performance of Phase 4 clinical trials as a condition of approval 
for an NDA. 
Progress reports detailing the results of the clinical trials must be submitted at least annually to the FDA and written 
IND safety reports must be submitted to the FDA and the investigators for serious and unexpected suspected adverse 
events, any clinically important increased rates of serious suspected adverse events compared to those listed in the 
protocol or investigator brochure, or findings from other studies or from animal or in vitro testing that suggests a 
significant risk for human subjects. Phase 1, Phase 2 and Phase 3 clinical trials may not be completed successfully within 
any specified period, if at all. Success in one phase does not mean that the results will be observed in subsequent phases. 
Each phase may involve multiple studies. If concerns arise about the safety of the product candidate, the FDA or other 
regulatory authorities can stop clinical trials by placing them on a “clinical hold” pending receipt of additional data, which 
can result in a delay or termination of a clinical development program. The sponsoring company, the FDA, or the IRB 
may suspend or terminate a clinical trial at any time on various grounds, including a finding that the patients 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. Additionally, some clinical trials are overseen by an independent group of qualified experts organized by the 
clinical trial sponsor, known as a data safety monitoring board or committee. This group provides authorization for 

22
whether or not a trial may move forward at designated check points based on access to certain data from the trial, and may 
suspend a clinical trial at any time on various grounds, including a finding that the research subjects are being exposed to 
an unacceptable health risk. 
In December 2022, with the passage of Food and Drug Omnibus Reform Act, or FDORA, Congress required 
sponsors to develop and submit a diversity action plan for each Phase 3 clinical trial or any other “pivotal study” of a new 
drug or biological product. These plans are meant to encourage the enrollment of more diverse patient populations in late-
stage clinical trials of FDA-regulated products. Specifically, actions plans must include the sponsor’s goals for 
enrollment, the underlying rationale for those goals, and an explanation of how the sponsor intends to meet them. In 
addition to these requirements, the legislation directs the FDA to issue new guidance on diversity action plans.
Sponsors of certain clinical trials are required to register and disclose certain clinical trial information on a public 
registry (clinicaltrials.gov) maintained by the U.S. National Institutes of Health, or NIH. In particular, information related 
to the product, patient population, phase of investigation, study sites and investigators and other aspects of the clinical trial 
is made public as part of the registration of the clinical trial. The failure to submit clinical trial information to 
clinicaltrials.gov, as required, is a prohibited act under the FDCA with violations subject to potential enforcement, 
including warnings and civil monetary penalties of up to $10,000 for each day the violation continues.
Concurrent with clinical trials, companies usually complete additional animal studies and must also develop 
additional information about the chemistry and physical characteristics of the drug as well as finalize a process for 
manufacturing the product in commercial quantities in accordance with cGMP requirements. The manufacturing process 
must be capable of consistently producing quality batches of the drug candidate and, among other things, we must develop 
methods for testing the identity, strength, quality and purity of the final drug product. Additionally, appropriate packaging 
must be selected and tested and stability studies must be conducted to demonstrate that the drug candidate does not 
undergo unacceptable deterioration over its shelf life.
NDA and FDA Review Process
The results of non-clinical studies and of the clinical trials, together with other detailed information, including 
extensive manufacturing information and information on the composition of the drug and proposed labeling, are submitted 
to the FDA as part of an NDA requesting approval to market the drug for one or more specified indications. The FDA 
reviews an NDA to determine, among other things, whether a drug is safe and effective for its intended use and whether 
the product is being manufactured in accordance with cGMP to assure and preserve the product’s identity, strength, 
quality and purity. FDA approval of an NDA must be obtained before a drug may be marketed in the U.S.
In addition, under the Pediatric Research Equity Act certain NDAs or supplements to an NDA must contain data to 
assess the safety and efficacy of the drug for the claimed indications in all relevant pediatric subpopulations and to support 
dosing and administration for each pediatric subpopulation for which the product is safe and effective. The FDA may 
grant deferrals for submission of pediatric data or full or partial waivers. Under the Best Pharmaceuticals for Children 
Act, the FDA may also issue a written request asking a sponsor to conduct pediatric studies related to a particular active 
moiety; if the sponsor agrees and meets certain requirements, the sponsor may be eligible to receive additional marketing 
exclusivity for its drug product containing such active moiety.
Under The Prescription Drug Fee User Act, or PDUFA, each NDA must be accompanied by a user fee, unless 
subject to a waiver. The FDA adjusts the PDUFA user fees on an annual basis. According to the FDA’s fee schedule, 
effective through September 30, 2025, the user fee for an application requiring clinical data, such as an NDA, is 
approximately $4.3 million. PDUFA also imposes an annual prescription drug program fee for human drugs of 
approximately $0.4 million. Fee waivers or reductions are available in certain circumstances, including a waiver of the 
application fee for the first application filed by a small business. Additionally, no user fees are assessed on NDAs for 
products designated as orphan drugs, unless the product also includes a non-orphan-designated indication.
The FDA reviews all NDAs submitted before it accepts them for filing, and may request additional information 
rather than accepting an NDA for filing. The FDA must make a decision on accepting an NDA for filing within 60 days of 
receipt. Once the submission is accepted for filing, the FDA begins an in-depth review of the NDA. Under the goals and 
policies agreed to by the FDA under PDUFA, the FDA aims to complete its initial review of an NDA and respond to the 

23
applicant within 10 months from the filing date for a standard NDA and within six months from the filing date for a 
priority NDA. The FDA does not always meet its PDUFA target action dates for standard and priority NDAs, and the 
review process is often significantly extended by FDA requests for additional information or clarification.
After the NDA submission is accepted for filing, the FDA reviews the NDA to determine, among other things, 
whether the proposed product is safe and effective for its intended use, and whether the product is being manufactured in 
accordance with cGMP to assure and preserve the product’s identity, strength, quality and purity. Before approving an 
NDA, the FDA will generally conduct a pre-approval inspection of the manufacturing facilities for the new product to 
determine whether the facilities comply with cGMPs. The FDA will not approve the product unless it determines that the 
manufacturing processes and facilities are in compliance with cGMP requirements and adequate to assure consistent 
production of the product within required specifications. 
Before approving an NDA, the FDA may also audit data from clinical trials to ensure compliance with GCP 
requirements and integrity of the data submitted in the NDA. With the passage of FDORA, Congress clarified the FDA’s 
authority to conduct inspections by expressly permitting inspection of facilities involved in the preparation, conduct, or 
analysis of clinical and non-clinical studies submitted to the FDA as well as other persons holding study records or 
involved in the study process.
The FDA may also re-analyze the clinical trial data, which could result in extensive discussions between the FDA 
and the applicant during the review process. The review and evaluation process for an NDA by the FDA is extensive and 
time consuming and may take longer than originally planned to complete, and we may not receive a timely approval, if at 
all. Additionally, the FDA may refer applications for novel drug products or drug products that present difficult questions 
of safety or efficacy to an advisory committee, typically a panel that includes clinicians and other experts, for review, 
evaluation and a recommendation as to whether the application should be approved and under what conditions. For 
example, the advisory committee may recommend or the FDA may determine that a Risk Evaluation and Mitigation 
Strategy, or REMS, program is necessary to ensure safe use of the product. The FDA is not bound by the 
recommendations of an advisory committee, but it considers such recommendations carefully when making decisions. 
After the FDA evaluates an NDA, it may issue an approval letter or a complete response letter. An approval letter 
authorizes commercial marketing of the drug with specific prescribing information for specific indications. A complete 
response letter indicates that the review cycle of the application is complete and the application is not ready for approval. 
A complete response letter usually describes all of the specific deficiencies in the NDA identified by the FDA. The 
complete response letter may require additional clinical data and/or one or more additional pivotal Phase 3 clinical trials, 
and/or other significant and time-consuming requirements related to clinical trials, non-clinical studies or manufacturing. 
If a complete response letter is issued, the applicant may either resubmit the NDA, addressing all of the deficiencies 
identified in the letter, or withdraw the application. Even if such additional data and information are submitted, the FDA 
may ultimately decide that the NDA does not satisfy the criteria for approval. Data obtained from clinical trials are not 
always conclusive, and the FDA may interpret data differently than we interpret the same data. 
There is no assurance that the FDA will ultimately approve a drug product for marketing in the U.S., and we may 
encounter significant difficulties or costs during the review process. If a product receives marketing approval, the 
approval may be significantly limited to specific patient populations and dosages or the indications for use may otherwise 
be limited, which could restrict the commercial value of the product. Further, the FDA typically requires that certain 
contraindications, warnings or precautions be included in the product labeling, and may condition the approval of the 
NDA on other changes to the proposed labeling, development of adequate controls and specifications, or a commitment to 
conduct post-marketing testing or clinical trials and surveillance to monitor the effects of approved products. For example, 
the FDA may require Phase 4 testing which may involve clinical trials designed to further assess a drug’s safety and/or 
efficacy and may require testing and surveillance programs to monitor the safety of approved products that have been 
commercialized. The FDA may also place other conditions on approvals including the requirement for a REMS to assure 
the safe use of the drug. If the FDA concludes a REMS is needed, the sponsor of the NDA must submit a proposed 
REMS. The FDA will not approve the NDA without an approved REMS if the FDA determines that a REMS is required. 
A REMS could include medication guides, physician communication plans, or elements to assure safe use, such as 
restricted distribution methods, patient registries and other risk minimization tools. Any limitations on approval, 
marketing or use for any of our products could restrict the commercial promotion, distribution, prescription or dispensing 

24
of those products. Product approvals may be withdrawn for non-compliance with regulatory requirements if problems 
occur following launch, or if the FDA determines that the product is no longer safe or effective.
Orphan Drug Designation
Under the Orphan Drug Act, the FDA may grant orphan designation to a drug product intended to treat a “rare 
disease or condition,” which is generally a disease or condition that affects fewer than 200,000 individuals in the U.S., or 
more than 200,000 individuals in the U.S., if there is no reasonable expectation that the cost of developing and making a 
drug product available in the U.S. for that disease or condition will be recovered from sales of the product. If orphan 
product designation is sought, it must be requested before submitting an NDA for the drug for the proposed rare disease or 
condition. If the FDA grants orphan drug designation, the common name of the therapeutic agent and its designated 
orphan use are disclosed publicly by the FDA. Orphan product designation does not, by itself, convey any advantage in or 
shorten the duration of the regulatory review and approval process.
If a product that has orphan designation subsequently receives the first FDA approval for the disease or condition for 
which it has such designation, the product is entitled to orphan product exclusivity, which means that the FDA may not 
approve any other sponsors’ applications to market the same drug for the indication for seven years, except in limited 
circumstances, such as a showing of clinical superiority to the product with orphan exclusivity. Orphan exclusivity 
operates independently from other regulatory exclusivities and other protection against generic competition, including 
patents that we hold for our products. A sponsor of a product application that has received an orphan drug designation 
may also be granted tax incentives for clinical research undertaken to support the application. In addition, the FDA may 
coordinate with the sponsor on research study design for an orphan drug and may exercise its discretion to grant 
marketing approval on the basis of more limited product safety and efficacy data than would ordinarily be required, based 
on the limited size of the applicable patient population.
Competitors, however, may receive approval of different products for the indication for which the orphan product 
has exclusivity, or obtain approval for the same product but for a different indication than that for which the orphan 
product has exclusivity. Orphan product exclusivity also could block the approval of one of our products for seven years if 
a competitor obtains approval of the same product as defined by the FDA, or if our product candidate is determined to be 
contained within the competitor’s product for the same indication or disease. If a drug designated as an orphan product 
receives marketing approval for an indication broader than what is designated, it may not be entitled to orphan product 
exclusivity. The FDA can revoke a product’s orphan drug exclusivity under certain circumstances, including when the 
holder of the approved orphan drug application is unable to assure the availability of sufficient quantities of the drug to 
meet patient needs. Orphan drug status in the EU has similar, but not identical, benefits. In the EU, orphan medicinal 
products enjoy ten years of orphan market exclusivity. In April 2023, the European Commission published a proposal to 
reform EU pharmaceutical law. This proposal intends to change the legislation regarding orphan medicinal products. In 
April 2024, the European Parliament adopted its position on the legislation, in which they set the baseline period for 
orphan market exclusivity at nine years (instead of the current ten years), which could be extended up to eleven years 
when the product meets specific requirements. The legislative process for this reform is expected to take several years, 
and adoption of the new legislation is not expected to take place before 2026. It is therefore currently uncertain if the 
proposal will be adopted in its current form, with the proposed modification of orphan market exclusivity, and it is 
uncertain if and when the revised legislation would enter into force.
In September 2021, the Court of Appeals for the 11th Circuit held that, for the purpose of determining the scope of 
market exclusivity, the term “same disease or condition” in the statute means the designated “rare disease or condition” 
and could not be interpreted by the FDA to mean the “indication or use.” Thus, the court concluded, orphan drug 
exclusivity applies to the entire designated disease or condition rather than the specifically designated “indication or use.” 
Although there have been legislative proposals to overrule this decision, they have not been enacted into law. On January 
23, 2023, the FDA announced that, in matters beyond the scope of that court order, the FDA will continue to apply its 
existing regulations tying orphan-drug exclusivity to the uses or indications for which the orphan drug was approved.

25
Expedited Development and Review Programs
The FDA has several programs that are intended to expedite or facilitate the process for reviewing new drugs that 
are intended to treat serious or life-threatening conditions and/or demonstrate the potential to address unmet medical 
needs for the condition and/or, if approved, would provide meaningful therapeutic benefit over existing treatments. Fast 
Track designation and Breakthrough Therapy designation are two of these programs and apply to the combination of the 
product and the specific indication for which it is being studied. The sponsor of a new drug or biologic may request the 
FDA to designate the drug as a Fast Track product at any time during the development of the product and may request the 
FDA to designate the drug as a Breakthrough Therapy based on preliminary clinical evidence that meets the criteria 
outlined in the FDA’s programs. Under the Fast Track or Breakthrough Therapy expedited programs, the FDA may 
review sections of the marketing application on a rolling basis before the complete NDA is submitted if the sponsor 
provides a schedule for the submission of the sections of the application, the FDA agrees to accept sections of the 
application and determines that the schedule is acceptable, and the sponsor pays any required user fees upon submission 
of the first section of the application.
Any product submitted to the FDA for marketing, including under a Fast Track or Breakthrough Therapy program, 
may be eligible for other types of FDA programs intended to expedite development and review, such as priority review 
and accelerated approval. 
Any product is eligible for priority review if it treats a serious condition and, if approved, would offer a significant 
improvement in the safety and effectiveness of treatment, diagnosis or prevention compared to marketed products. 
Significant improvement may be shown by evidence of increased effectiveness for the treatment of a condition, 
elimination or substantial reduction of a treatment-limiting product reaction, documented enhancement of patient 
compliance that may lead to improvement in serious outcomes, and evidence of safety and effectiveness in a new 
subpopulation. The FDA will attempt to direct additional resources to the evaluation of an application for a new drug 
designated for priority review in an effort to facilitate the review, and to shorten the FDA’s goal for taking action on a 
marketing application from ten months to six months from the date of the NDA filing. 
A product may also be eligible for accelerated approval if the product is intended to treat a serious or life-threatening 
illness and, if approved, would provide meaningful therapeutic benefit over existing treatments. Accelerated approval for 
a product means that it may be approved on the basis of adequate and well-controlled clinical trials establishing that the 
product has an effect on a surrogate endpoint that is reasonably likely to predict a clinical benefit, or on the basis of an 
effect on a clinical endpoint other than survival or irreversible morbidity. As a condition of approval, the FDA may 
require that a sponsor of a drug receiving accelerated approval perform adequate and well-controlled post-marketing 
clinical trials. If the FDA concludes that a drug shown to be effective can be safely used only if distribution or use is 
restricted, it will require such post-marketing restrictions, as it deems necessary to assure safe use of the drug, such as:
•
distribution restricted to certain facilities or physicians with special training or experience; or
•
distribution conditioned on the performance of specified medical procedures.
The limitations imposed would be commensurate with the specific safety concerns presented by the drug. In 
addition, the FDA currently requires pre-approval of promotional materials as a condition for accelerated approval, which 
could adversely impact the timing of the commercial launch of the product. 
With the passage of FDORA, Congress modified certain provisions governing accelerated approval of drug and 
biologic products. Specifically, the new legislation authorized the FDA to require a sponsor to have its confirmatory 
clinical trial underway before accelerated approval is awarded, require the sponsor to submit progress reports on its post-
approval studies to the FDA every six months (until the study is completed) and use expedited procedures to withdraw 
accelerated approval of an NDA, if the confirmatory trial fails to verify the product’s clinical benefit. Further, FDORA 
requires the agency to publish on its website “the rationale for why a post-approval study is not appropriate or necessary” 
whenever it decides not to require such a study upon granting accelerated approval.
Fast Track designation, priority review, accelerated approval and Breakthrough Therapy designation do not change 
the standards for approval, but may expedite the development or approval process.

26
Pediatric Trials
The Food and Drug Administration Safety and Innovation Act, which was signed into law on July 9, 2012, amended 
the FDCA to require that a sponsor who is planning to submit a marketing application for a drug that includes a new 
active ingredient, new indication, new dosage form, new dosing regimen or new route of administration submit an initial 
Pediatric Study Plan, or PSP, within sixty days of an end-of-Phase 2 meeting or as may be agreed between the sponsor 
and the FDA. The initial PSP must include an outline of the pediatric study or studies that the sponsor plans to conduct, 
including study objectives and design, age groups, relevant endpoints and statistical approach, or a justification for not 
including such detailed information, and any request for a deferral of pediatric assessments or a full or partial waiver of 
the requirement to provide data from pediatric studies, along with supporting information. The FDA and the sponsor must 
reach agreement on the PSP. A sponsor can submit amendments to an agreed-upon initial PSP at any time if changes to 
the pediatric plan need to be considered based on data collected from non-clinical studies, early phase clinical trials, 
and/or other clinical development programs. The FDA, if it learns of new information, may also request that the sponsor 
amend the initial PSP. The FDA may send a non-compliance letter to sponsors who have failed to submit their required 
pediatric assessments and have failed to seek or obtain a deferral, deferral extension or waiver, or have failed to request 
approval for a required pediatric formulation.
Post-Marketing Requirements
Following approval of a new product, a pharmaceutical company and the approved product are subject to continuing 
regulation by the FDA, including, among other things, monitoring and recordkeeping activities, reporting to the applicable 
regulatory authorities of adverse experiences with the product, providing the regulatory authorities with updated safety 
and efficacy information, product sampling and distribution requirements, and complying with promotion and advertising 
requirements, which include, among others, standards for direct-to-consumer advertising, restrictions on promoting drugs 
for uses or in patient populations that are not described in the drug’s approved labeling (known as “off-label use”), 
limitations on industry-sponsored scientific and educational activities, and requirements for promotional activities 
involving the Internet. 
Although physicians may legally prescribe available drugs for off-label uses, manufacturers may not market or 
promote such off-label uses. It may be permissible, under very specific, narrow conditions, for a manufacturer to engage 
in non-promotional, non-misleading communication regarding off-label information, such as distributing or discussing 
certain scientific or medical journal information. For example, sponsors of products that have not been approved may 
proactively communicate to payors certain information about products in development to help expedite patient access 
upon product approval.
Prescription drug promotional materials must be submitted to the FDA in conjunction with their first use. Further, if 
there are any modifications to the drug, including changes in indications, labeling, or manufacturing processes or 
facilities, the applicant may be required to submit and obtain FDA approval of a new NDA or NDA supplement, which 
may require the applicant to develop additional data or conduct additional non-clinical studies and clinical trials. As with 
new NDAs, the review process is often significantly extended by FDA requests for additional information or clarification. 
Any distribution of prescription drug products and pharmaceutical samples must comply with the U.S. Prescription Drug 
Marketing Act, if applicable, and the Drug Supply Chain Security Act.
FDA regulations also require that approved products be manufactured in specific approved facilities and in 
accordance with cGMP. We rely, and expect to continue to rely, on third parties for the production of clinical and 
commercial quantities of our products in accordance with cGMP regulations. NDA holders using contract manufacturers, 
laboratories or packagers are responsible for the selection and monitoring of qualified firms, and, in certain circumstances, 
qualified suppliers to these firms. These manufacturers must comply with cGMP regulations that require, among other 
things, quality control and quality assurance as well as the corresponding maintenance of records and documentation and 
the obligation to investigate and correct any deviations from cGMP. 
Drug manufacturers and other entities involved in the manufacture and distribution of approved drugs are required to 
register their establishments with the FDA and certain state agencies, and are subject to periodic unannounced inspections 
by the FDA and certain state agencies for compliance with cGMP and other laws. The PREVENT Pandemics Act, which 

27
was enacted in December 2022, clarifies that foreign drug manufacturing establishments are subject to registration and 
listing requirements even if a drug or biologic undergoes further manufacture, preparation, propagation, compounding, or 
processing at a separate establishment outside the United States prior to being imported or offered for import into the 
United States.
Accordingly, manufacturers must continue to expend time, money, and effort in the area of production and quality 
control to maintain cGMP compliance. The discovery of violative conditions, including failure to conform to cGMPs, 
could result in enforcement actions that interrupt the operation of any such facilities or the ability to distribute products 
manufactured, processed or tested by them. Discovery of problems with a product after approval may result in restrictions 
on a product, manufacturer, or holder of an approved NDA, including, among other things, recall or withdrawal of the 
product from the market.
Discovery of previously unknown problems with a product or the failure to comply with applicable FDA 
requirements can have negative consequences, including adverse publicity, administrative enforcement, warning or 
untitled letters from the FDA, mandated corrective advertising or communications with doctors, and civil penalties or 
criminal prosecution, among others. Newly discovered or developed safety or effectiveness data may require changes to a 
product’s approved labeling, including the addition of new warnings and contraindications, and also may require the 
implementation of other risk management measures. Also, new government requirements, including those resulting from 
new legislation, may be established, or the FDA’s policies may change, which could delay or prevent regulatory approval 
of our products under development.
Other Regulatory Matters
Manufacturing, sales, promotion and other activities following product approval are also subject to regulation by 
numerous regulatory authorities in addition to the FDA, including, in the U.S., the other divisions of the Department of 
Health and Human Services, or HHS; the U.S. Department of Justice; the DEA; the Consumer Product Safety 
Commission; the Federal Trade Commission; the Occupational Safety and Health Administration; the Environmental 
Protection Agency; and state and local governments.
In the U.S., a drug product approved by the FDA may also be subject to regulation under the Controlled Substances 
Act, or CSA, as a controlled substance. The CSA is administered by the DEA and establishes, among other things, certain 
registration, security, recordkeeping, reporting, import, export and other requirements for controlled substances. The CSA 
classifies controlled substances into five schedules: Schedule I, II, III, IV or V. FDA approved pharmaceutical products 
may be listed in Schedule II, III, IV or V, with Schedule II substances considered to present the highest potential for abuse 
or dependence and Schedule V substances the lowest relative risk of abuse among such substances. An approved drug 
product or drug candidate that has not yet been approved by the FDA may be subject to scheduling as a controlled 
substance under the CSA, depending on the drug’s potential for abuse. For a drug approved by the FDA and determined to 
require control under the CSA, the CSA requires the DEA to issue an interim final order scheduling the drug within 90 
days after the DEA receives notice from HHS that the FDA has approved the drug and the DEA receives from HHS the 
scientific and medical evaluation completed by the FDA. Following recommendation by the FDA, zuranolone and 
brexanolone each received a Schedule IV classification from the DEA.
In the U.S., arrangements and interactions with healthcare providers, third-party payors, patients and others expose 
us to broadly applicable anti-fraud and abuse, anti-kickback, false claims and other healthcare laws and regulations. These 
broadly applicable laws and regulations may constrain the business or financial arrangements or relationships through 
which we sell, market and distribute our approved products and any future products that may obtain marketing approval. 
In the U.S., federal and state healthcare laws and regulations that may affect our operations include:
•
The federal Anti-Kickback Statute, which makes it illegal for any person, including a company marketing a 
prescription drug (or a party acting on its behalf), to knowingly and willfully solicit, receive, offer, or pay any 
remuneration (including any kickback, bribe or rebate), directly or indirectly, in cash or in kind, that is 
intended to induce or reward the referral of an individual or purchase, lease or order, or the arranging for or 
recommending the purchase or order, of a particular item or service, for which payment may be made in whole 
or in part under a federal healthcare program, such as Medicare or Medicaid. This statute has been interpreted 
to apply to arrangements between pharmaceutical companies on one hand and prescribers, patients, purchasers 

28
and formulary managers on the other. Liability under the Anti-Kickback Statute may be established without 
proving actual knowledge of the statute or specific intent to violate it. In addition, the government may assert 
that a claim, including 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. Although there are a 
number of statutory exemptions and regulatory safe harbors to the federal Anti-Kickback Statute protecting 
certain common business arrangements and activities from prosecution or regulatory sanctions, the exemptions 
and safe harbors are drawn narrowly. Practices that involve remuneration to those who prescribe, purchase, or 
recommend pharmaceutical and biological products, including certain discounts, or engaging such individuals 
as consultants, advisors, or speakers, may be subject to scrutiny if they do not fit squarely within an exemption 
or safe harbor. Our practices may not in all cases meet all of the criteria for safe harbor protection from anti-
kickback liability. Moreover, there are no safe harbors for many common practices, such as educational and 
research grants, charitable donations, product support and patient assistance. Violations of this law may be 
punishable by up to ten years in prison, criminal fines, damages, administrative civil money penalties, and the 
potential for exclusion from participation in federal healthcare programs. 
•
The federal civil False Claims Act, which prohibits anyone 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, using, or causing to be made or used a false record or statement material to a false or fraudulent claim 
or knowingly and improperly avoiding, decreasing or concealing an obligation to pay money to the federal 
government. Actions under the False Claims Act may be brought by the federal government or as a qui tam 
action by a private individual in the name of the government. Many pharmaceutical manufacturers have been 
investigated and have reached substantial financial settlements with the federal government under the False 
Claims Act for a variety of alleged improper activities. The government may deem companies to have 
“caused” the submission of false or fraudulent claims by, for example, providing inaccurate billing or coding 
information to customers or promoting a product off-label. In addition, our activities relating to the reporting of 
prices used to calculate Medicaid rebate information and other information affecting federal, state, and third-
party reimbursement for our products, and the sale and marketing of our products, are subject to scrutiny under 
this law. Penalties for a False Claims Act violation may include three times the actual damages sustained by 
the government, plus significant civil penalties for each separate false or fraudulent claim, and the potential for 
exclusion from participation in federal healthcare programs.
•
Numerous federal and state laws, including state data breach notification laws, state health information and/or 
genetic privacy laws, and federal and state consumer protection laws (e.g., Section 5 of the Federal Trade 
Commission Act and the California Consumer Privacy Act), govern the collection, use, and disclosure and 
protection of health-related and other personal information. Failure to comply with these laws and regulations 
could result in government enforcement actions and create liability, private litigation, or adverse publicity. In 
addition, we or our collaborators may obtain health information from third parties, such as hospitals, healthcare 
professionals, and research institutions, that are subject to privacy and security requirements under the federal 
Health Insurance Portability and Accountability Act of 1996, and its implementing regulations, or collectively, 
HIPAA. HIPAA imposes privacy and security obligations on covered entity healthcare professionals, health 
plans, and healthcare clearinghouses, as well as their “business associates” – independent contractors or agents 
of covered entities that receive or obtain protected health information in connection with providing a service 
for or on behalf of a covered entity. Although we are not directly subject to the HIPAA information privacy 
and security provisions – other than with respect to providing certain employee benefits – we could potentially 
be subject to criminal penalties if we or our agents knowingly receive individually identifiable health 
information maintained by a HIPAA-covered entity in a manner that is not authorized or permitted by HIPAA. 
In addition, HIPAA does not replace federal, state, or other laws that may grant individuals even greater 
privacy protections. 
•
The HIPAA fraud provisions, which impose criminal and civil liability for knowingly and willfully executing a 
scheme to defraud any healthcare benefit program, including private third-party payors, and prohibit 
knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, 
fictitious or fraudulent statement or representation, or making or using any false writing or document knowing 
the same to contain any materially false fictitious or fraudulent statement or entry, in connection with the 
delivery of or payment for healthcare benefits, items or services.
•
The federal Physician Payment Sunshine Act, implemented as the Open Payments Program, which requires 
manufacturers of drugs, devices, biologics, and medical supplies for which payment is available under 

29
Medicare, Medicaid or the Children’s Health Insurance Program, or CHIP, (with certain exceptions) to report 
annually to the Centers for Medicare & Medicaid Services, or CMS, the agency that administers the Medicare 
and Medicaid programs, information related to direct or indirect payments and other transfers of value to 
physicians, physician assistants, nurse practitioners, clinical nurse specialists, certified nurse anesthetists, and 
certified nurse-midwives, and teaching hospitals, as well as ownership and investment interests held in the 
company by physicians and their immediate family members. The reportable information is publicly available 
on a searchable website. 
•
Analogous state and local laws and regulations, such as state anti-kickback and false claims laws, which may 
apply to items or services reimbursed under Medicaid and other state programs or, in several states, regardless 
of the payor. We are also subject to other state laws that require pharmaceutical companies to comply with the 
pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated 
by the federal government or otherwise restrict payments that may be made to healthcare professionals; state 
laws that restrict the ability of manufacturers to offer co-pay support to patients for certain prescription drugs; 
state laws that require drug manufacturers to report information related to clinical trials, or information related 
to payments and other transfers of value to physicians and other healthcare professionals or marketing 
expenditures; state laws and local ordinances that require identification or licensing of sales representatives; 
and state laws governing the privacy and security of health information in certain circumstances, many of 
which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating 
compliance efforts.
Substantial resources are necessary to ensure that our business arrangements and interactions with healthcare 
professionals, third-party payors, patients and others comply with applicable healthcare laws and regulations. Although 
compliance programs can mitigate the risk of investigation, prosecution, and/or liability for violations of these laws, the 
risks cannot be entirely eliminated. It is possible that federal or state governmental authorities will conclude that our 
business practices do not comply with current or future statutes, regulations or case law, and if we are found to be in 
violation of any of these laws or any other federal or state governmental regulations, we may be subject to significant 
civil, criminal and administrative penalties, imprisonment, damages, fines, exclusion from government-funded healthcare 
programs such as Medicare and Medicaid, or the curtailment or restructuring of our operations. Any action against us for 
violation of these laws or regulations, even if we successfully defend against it, could cause us to incur significant legal 
expenses and divert our management’s attention from the operation of our business.
Numerous other laws may apply to our products. Pricing and rebate programs must comply with the Medicaid rebate 
requirements of the U.S. Omnibus Budget Reconciliation Act of 1990 and more recent requirements in the Patient 
Protection and Affordable Care Act, as amended, and its implementing regulations (collectively referred to herein as the 
ACA (addressed further below in the section on “U.S. Healthcare Reform”)). If products are made available to authorized 
users of the Federal Supply Schedule of the General Services Administration, additional laws and requirements apply. 
Many states impose various requirements on pharmaceutical manufacturers to report development costs and pricing 
information when prices are increased. Penalties for late or faulty reporting can be significant. Products must meet 
applicable child-resistant packaging requirements under the U.S. Poison Prevention Packaging Act. Manufacturing, sales, 
promotion and other activities are also potentially subject to federal and state consumer protection and unfair competition 
laws.
The handling of any controlled substances must comply with the CSA and Controlled Substances Import and Export 
Act.
The distribution of pharmaceutical products is subject to additional requirements and regulations, including 
extensive record-keeping, licensing, storage and security requirements intended to prevent the unauthorized sale of 
pharmaceutical products. The failure to comply with any of these laws or regulatory requirements subjects firms to 
possible legal or regulatory action. Depending on the circumstances, failure to meet applicable regulatory requirements 
can result in criminal prosecution, fines or other penalties, injunctions, issuance of warning or untitled letters, recall or 
seizure of products, total or partial suspension of production, denial or withdrawal of product approvals, or refusal to 
allow a firm to enter into supply contracts, including government contracts. Federal regulators, state attorneys general, and 
plaintiffs’ attorneys have been and will likely continue to be active in this space. Any action against us for violation of 
these laws, even if we successfully defend against it, could cause us to incur significant legal expenses and divert our 

30
management’s attention from the operation of our business. Prohibitions or restrictions on sales or withdrawal of future 
products marketed by us could materially affect our business in an adverse way.
Many of these laws differ from each other in significant ways and may not have the same effect, thus complicating 
compliance efforts. Many of the state laws enable a state attorney general to bring actions and provide private rights of 
action to consumers as enforcement mechanisms. There is also heightened sensitivity around certain types of health 
information, such as sensitive condition information or the health information of minors, which may be subject to 
additional protections. Compliance with these laws is difficult, constantly evolving, and time consuming. Changes in 
statutes, regulations or the interpretation of existing laws or regulations could impact our business in the future by 
requiring, for example: (i) changes to our manufacturing arrangements; (ii) additions or modifications to product labeling; 
(iii) the recall or discontinuation of our products; or (iv) additional record-keeping requirements. If any such changes were 
to be imposed, they could adversely affect the operation of our business.
U.S. Patent Term Restoration and Marketing Exclusivity
Depending upon the timing, duration and specifics of the FDA approval of our drug candidates, if any, some of our 
U.S. patents may be eligible for limited patent term extension under the Hatch-Waxman Act. The Hatch-Waxman Act 
permits a patent restoration term of up to five years as compensation for patent term lost during product development and 
the FDA regulatory review process. However, patent term restoration cannot extend the remaining term of a patent 
beyond a total of 14 years from the product’s approval date. The patent term restoration period is generally one-half the 
time between the effective date of an IND and the submission date of an NDA, or the testing phase, plus the time between 
the submission date of an NDA and the approval of that application, or the approval phase. This patent term restoration 
period may be reduced by the FDA if it finds that applicant did not act with due diligence during the testing phase or the 
approval phase. Only one patent applicable to an approved drug is eligible for the extension and the application for the 
extension must be submitted prior to the expiration of the patent. The U.S. PTO, in consultation with the FDA, reviews 
and approves the application for any patent term extension or restoration. In the future, if circumstances permit, we intend 
to apply for restoration of patent term for one of our then owned or licensed patents, if any, to add patent life beyond its 
current expiration date, depending on the expected length of the clinical trials and other factors involved in the filing of 
the relevant NDA. Even if, at the relevant time, we have a valid issued patent covering our product, we may not be 
granted an extension if we were, for example, to fail to apply within applicable deadlines, to fail to apply prior to 
expiration of relevant patents or otherwise to fail to satisfy applicable requirements. Moreover, the applicable time period 
or the scope of patent protection afforded could be less than we request. If we are unable to obtain patent term extension 
or restoration or the term of any such extension is less than we request, and we do not have any other exclusivity, our 
competitors may obtain approval of competing products following our patent expiration and our ability to generate 
revenues could be materially adversely affected.
Some of our products may also be entitled to certain non-patent-related data exclusivity under the FDCA. The 
FDCA provides a five-year period of non-patent data exclusivity within the U.S. to the first applicant to obtain approval of 
an NDA for a new chemical entity, or NCE. A drug is a new chemical entity if the FDA has not previously approved any 
other new drug containing the same active moiety, which is the molecule or ion responsible for the action of the drug 
substance. During the exclusivity period, an abbreviated new drug application, or ANDA, or a 505(b)(2) NDA may not be 
submitted by another company for another drug containing the same active moiety, regardless of whether the drug is 
intended for the same indication as the original innovator drug or for another indication, where the applicant does not own 
or have a legal right of reference to all the data required for approval. However, an application may be submitted after 
four years if it contains a certification of patent invalidity or non-infringement to one of the patents listed with the FDA 
Orange Book by the innovator NDA holder. The FDCA also provides three years of marketing exclusivity for a drug 
product that contains an active moiety that has been previously approved, if the application contains reports of new 
clinical investigations, other than bioavailability studies, that were conducted or sponsored by the applicant and that are 
deemed by the FDA to be essential to the approval of the application (for example, for new indications, dosages or 
strengths of an existing drug). Three-year exclusivity prevents the FDA from approving ANDAs and 505(b)(2) 
applications that rely on the information that served as the basis of granting three-year exclusivity. This three-year 
exclusivity covers only the modification for which the drug received approval on the basis of the new clinical 
investigations, and does not prohibit the FDA from approving ANDAs for drugs containing the active agent for the 
original indication or condition of use. Five-year and three-year exclusivity will not delay the submission or approval of a 

31
full NDA. However, an applicant submitting a full NDA would be required to conduct or obtain a right of reference to all 
of the non-clinical studies and adequate and well-controlled clinical trials necessary to demonstrate safety and efficacy. 
We have obtained five-year NCE exclusivity for brexanolone and zuranolone and plan to seek NCE exclusivity for our 
current and future product candidates, if eligible. The NCE exclusivity for brexanolone expired in June 2024, five years 
following approval of ZULRESSO.
European Union Drug Development
In the European Economic Area, or EEA, our future products may also be subject to extensive regulatory 
requirements. As in the U.S., medicinal products can only be marketed if a marketing authorization from the competent 
regulatory authorities in the EU has been obtained.
Similar to the U.S., the various phases of non-clinical and clinical research in the EU are subject to significant 
regulatory controls. Although the EU Clinical Trials Directive 2001/20/EC, or the Clinical Trials Directive, has sought to 
harmonize the EU clinical trials regulatory framework, setting out common rules for the control and authorization of 
clinical trials in the EU, the EU Member States have transposed and applied the provisions of the Clinical Trials Directive 
in a manner that is often not uniform. This has led to variations in the rules governing the conduct of clinical trials in the 
individual EU Member States. Under the regime of the Clinical Trials Directive, before a clinical trial can be initiated, it 
must be approved in each EU Member State where there is a site at which the trial is to be conducted by two distinct 
bodies: the National Competent Authority, or NCA, and one or more ethics committees. Under the regime of the Clinical 
Trials Directive, all suspected unexpected serious adverse reactions to the investigated drug that occur during the clinical 
trial have to be reported to the NCA and ethics committees of the Member State where they occurred.
In order to streamline the regulation of clinical trials across the EU, the EU Parliament has adopted Regulation (EU) 
No 536/2014, or the EU Clinical Trials Regulation. The EU Clinical Trials Regulation, which repeals and replaces the 
Clinical Trials Directive, introduces a complete overhaul of the existing regulation of clinical trials for medicinal products 
in the EU, including a new coordinated procedure for authorization of clinical trials that is reminiscent of the mutual 
recognition procedure for marketing authorization of medicinal products, and increased obligations on sponsors to publish 
clinical trial results. The main characteristics of the regulation include: a streamlined application procedure through a 
single entry point, referred to as the “EU portal”; a single set of documents to be prepared and submitted for the 
application as well as simplified reporting procedures for clinical trial sponsors; and a harmonized procedure for the 
assessment of applications for clinical trials, which is divided in two parts. 
The EU Clinical Trials Regulation became effective on January 31, 2022, and is applicable directly in all countries 
of the EEA (which is comprised of 27 Member States of the EU plus Norway, Iceland and Liechtenstein). The EU 
Clinical Trials Regulation allows for starting and conducting a clinical trial in accordance with the Clinical Trials 
Directive during a transitional period which ended on January 31, 2023. Clinical trials authorized under the Clinical Trials 
Directive before January 31, 2023 can continue to be conducted under the Clinical Trials Directive until January 31, 2025. 
Any application to transition ongoing trials from the Clinical Trials Directive to the new EU Clinical Trials Regulation 
will need to be submitted and authorized before the end of the transitional period. The EU Clinical Trials Regulation is 
intended to simplify and streamline the approval of clinical trials in the EEA. 
In the EU, pediatric data or an approved Pediatric Investigation Plan, or PIP, or waiver, is required to have been 
approved by the European Medicines Agency, or EMA, prior to submission of a marketing authorization application to 
the EMA or the competent authorities of the EU Member States. In some EU countries, we may also be required to have 
an approved PIP before we can begin enrolling pediatric patients in a clinical trial. 
European Union Drug Review and Approval and Post-marketing Requirements
In the EEA, medicinal products can only be commercialized after a related marketing authorization has been 
granted. Marketing authorization for medicinal products can be obtained through several different procedures. These are 
through a centralized, mutual recognition procedure, decentralized procedure, or national procedure (if marketing 
authorization is sought for a single EU Member State). The centralized procedure allows a company to submit a single 
application to the EMA. If a related positive opinion is provided by the EMA, the European Commission will grant a 
centralized marketing authorization that is valid in all EEA countries.

32
The United Kingdom, or UK, withdrew from the EU on January 31, 2020, commonly referred to as Brexit. 
Marketing authorizations granted through the EU centralized procedure continue to be valid in Northern Ireland by virtue 
of the Northern Ireland Protocol, but such EU marketing authorizations are not valid in the rest of the UK (England, 
Wales and Scotland, or collectively Great Britain). EU marketing authorizations existing as at the end of the Brexit 
transition period on December 31, 2020, were automatically converted into Great Britain marketing authorizations as of 
January 1, 2021. Until the end of 2023, a marketing authorization for Great Britain can be applied for on an expedited 
timetable through the UK European Commission Decision Reliance Procedure, after having received a positive opinion 
from the EMA’s Committee for Medicinal Products for Human Use. Beginning on January 1, 2024, the new International 
Recognition Procedure, or IRP, has replaced the UK European Commission Decision Reliance Procedure. The 
decentralised reliance procedure has been incorporated under the umbrella of the IRP. Under the IRP, a marketing 
authorization for Great Britain can be obtained on the basis of a marketing authorization granted in the U.S. or the EU. 
The EU centralized procedure is mandatory for certain types of products, such as biotechnology medicinal products, 
orphan medicinal products, and medicinal products containing a new active substance indicated for the treatment of HIV, 
AIDS, cancer, neurodegenerative disorders, diabetes, auto-immune and other immune dysfunctions and viral diseases. 
The centralized procedure is optional for products containing a new active substance that is not yet authorized in the EEA, 
or for products that constitute a significant therapeutic, scientific or technical innovation or for which grant of centralized 
marketing authorization is in the interest of patients in the EU.
The decentralized authorization procedure permits companies to file identical applications for authorization to 
several EU Member States simultaneously for a medicinal product that has not yet been authorized in any EU Member 
State. The competent authorities of a single EU Member State, the reference member state, is appointed to review the 
application and provide an assessment report. The competent authorities of the other EU Member States, the concerned 
member states, are subsequently required to grant marketing authorization for their territories on the basis of this 
assessment. The only exception to this is where an EU Member State considers that there are concerns of potential serious 
risk to public health related to authorization of the product. In these circumstances, the matter is submitted to the Heads of 
Medicines Agencies for review. The mutual recognition procedure allows companies that have a medicinal product 
already authorized in one EU Member State to apply for this authorization to be recognized by the competent authorities 
in other EU Member States.
The maximum timeframe for the evaluation of a marketing authorization application in the EU is 210 days, not 
including clock stops during which applicants respond to questions from the competent authority. The initial marketing 
authorization granted in the EU is valid for five years. The authorization may be renewed and valid for an unlimited 
period unless the national competent authority or the European Commission decides on justified grounds to proceed with 
one additional five-year renewal period. The renewal of a marketing authorization is subject to a re-evaluation of the risk-
benefit balance of the product by the national competent authorities or the EMA.
The holder of an EU marketing authorization for a medicinal product must also comply with the EU’s 
pharmacovigilance legislation. This includes requirements to conduct pharmacovigilance, or the assessment and 
monitoring of the safety of medicinal products.
Various requirements apply to the manufacture and distribution of medicinal products in the EU market. 
Manufacture of medicinal products in the EU requires a manufacturing authorization, and import of medicinal products 
into the EU requires a manufacturing authorization allowing for import. The manufacturing authorization holder must 
comply with various requirements set out in the applicable EU laws, regulations and guidance. These requirements 
include compliance with EU cGMP standards when manufacturing medicinal products and active pharmaceutical 
ingredients, or APIs, including the manufacture of APIs outside of the EU with the intention to import the APIs into the 
EU. Similarly, the distribution of medicinal products within the EU is subject to compliance with the applicable EU laws, 
regulations and guidelines, including the requirement to hold appropriate authorizations for distribution granted by the 
competent authorities of the EU Member States. Marketing authorization holders and/or manufacturing authorization 
holders and/or distribution authorization holders may be subject to civil, criminal or administrative sanctions, including 
suspension of manufacturing authorization, in case of non-compliance with the EU or EU Member States’ requirements 
applicable to the manufacturing of medicinal products.

33
In the EU, the advertising and promotion of medicinal products are subject to EU Member States’ laws governing 
promotion of medicinal products, interactions with physicians and other healthcare professionals, misleading and 
comparative advertising and unfair commercial practices. For example, applicable laws require that promotional materials 
and advertising in relation to medicinal products comply with the product’s Summary of Product Characteristics, or 
SmPC, as approved by the competent authorities in connection with a marketing authorization approval. The SmPC is the 
document that provides information to physicians concerning the safe and effective use of the product. Promotional 
activity that does not comply with the SmPC is considered off-label and is prohibited in the EU. Breaches of the rules 
governing the promotion of medicinal products in the EU could be penalized by civil, criminal or administrative 
sanctions, which may include fines and imprisonment. These laws may further limit or restrict the advertising and 
promotion of medicinal products to the general public and may also impose limitations on promotional activities with 
healthcare professionals.
European Union Regulatory Data Exclusivity
In the EU, innovative medicinal products that are subject to marketing authorization on the basis of a full dossier, 
and do not fall within the scope of the concept of global marketing authorization, qualify for eight years of data 
exclusivity upon marketing authorization and an additional two years of market exclusivity. The concept of global 
marketing authorization prevents the same marketing authorization holder or members of the same group, or companies 
that have concluded tacit or explicit agreements concerning the marketing of the same medicinal product, from obtaining 
separate data and market exclusivity periods for medicinal products that contain the same active substance. This data 
exclusivity, if granted, prevents regulatory authorities in the EU from referencing the innovator’s data to assess a generic 
application or biosimilar application for eight years from the date of authorization of the innovative product, after which a 
generic or biosimilar marketing authorization application can be submitted, and the innovator’s data may be referenced. 
However, the generic product or biosimilar products cannot be marketed in the EU for a further two years thereafter. The 
overall ten-year period may be extended for a further year to a maximum of 11 years if, during the first eight years of 
those ten years, the marketing authorization holder obtains an authorization for one or more new therapeutic indications 
which, during the scientific evaluation prior to their authorization, are held to bring a significant clinical benefit in 
comparison with existing therapies. In April 2023, the European Commission published a proposal to reform the current 
European pharmaceutical legislative framework with a new Directive and Regulation to reduce the regulatory data 
protection period. The European Commission proposed to reduce the baseline regulatory data protection from eight years 
to six years. In the adopted position of the European Parliament, the baseline of eight years of data protection will be 
reduced to seven and a half years. The legislative process for this reform is expected to take several years, and adoption of 
the new legislation is not expected to take place before 2026. It is currently uncertain if the proposal will be adopted in its 
current form, with the modification of regulatory data protection, and it is uncertain if and when the revised legislation 
would enter into force.
European Union Orphan Designation and Exclusivity
In the EU, orphan drug designations are granted by the European Commission based on a scientific opinion by the 
EMA’s Committee for Orphan Medicinal Products in relation to medicinal products that are intended for the diagnosis, 
prevention or treatment of life-threatening or chronically debilitating conditions affecting not more than 5 in 10,000 
persons in the EU and in relation to which there exists no satisfactory method of diagnosis, prevention, or treatment (or 
the product would be a significant benefit to those affected). Additionally, designation is granted for products intended for 
the diagnosis, prevention, or treatment of a life-threatening, seriously debilitating or serious and chronic condition and 
when, without incentives, it is unlikely that sales of the drug in the EU would be sufficient to justify the necessary 
investment in developing the medicinal product.
Orphan medicinal products are entitled to ten years of exclusivity in all EU Member States. However, marketing 
authorization may be granted to a similar medicinal product with the same orphan indication during the ten-year period 
with the consent of the marketing authorization holder for the original orphan medicinal product or if the manufacturer of 
the original orphan medicinal product is unable to supply sufficient quantities of the product. Marketing authorization may 
also be granted to a similar medicinal product with the same orphan indication if the similar product is deemed safer, more 
effective or otherwise clinically superior to the original orphan medicinal product. The period of market exclusivity may, 
in addition, be reduced to six years if it is established that the criteria for orphan designation are no longer met, such as if 

34
it can be demonstrated on the basis of available evidence that the original orphan medicinal product is sufficiently 
profitable not to justify maintenance of market exclusivity.
In addition, grant of orphan designation by the European Commission also entitles the holder of this designation to 
financial incentives such as reduction of fees or fee waivers. Orphan drug designation must be requested before 
submitting an application for marketing authorization. Orphan drug designation does not, in itself, convey any advantage 
in, or shorten the duration of, the regulatory review and authorization process. In April 2023, the European Commission 
published a proposal to reform EU pharmaceutical law regarding orphan medicinal products that, if adopted in its current 
form, would shorten the baseline for the orphan market exclusivity from ten years to nine years. The orphan market 
exclusivity period could, however, be extended up to eleven years if specific requirements are met.
European Union Data Protection
EU Member States and other jurisdictions where we may in the future operate, including the UK, have adopted data 
protection laws and regulations, which impose significant compliance obligations. For example, the General Data 
Protection Regulation, or GDPR, imposes strict obligations and restrictions on the processing of personal data, including 
ensuring the lawfulness of processing personal data (including having a lawful basis for processing personal data, which 
may require in certain instances obtaining valid consent of the individuals to whom the personal data relates , providing 
detailed information about the processing activities to the individuals, having appropriate contractual arrangements for 
sharing personal data with third parties where required (such as with vendors or clinical trial sites), ensuring that 
appropriate transfer mechanisms are used for transferring personal data out of the European Economic Area and/or the 
UK to other countries, including the U.S., having appropriate technical and organizational security and confidentiality 
measures in place to protect personal data, reporting in certain instances personal data breaches to data protection 
authorities and/or affected individuals, appointing data protection officers, conducting data protection impact assessments, 
responding to and handling of privacy rights requests, and having appropriate policies and procedures in place to be able 
to demonstrate compliance with the GDPR. Violation of these data protection obligations may result in the imposition of 
substantial potential fines. 
With regard to transfer of personal data, the GDPR restricts the ability of companies to transfer personal data from 
the EEA, including the EU, UK, and Switzerland, to the U.S. and other countries, which may adversely affect our ability 
to transfer personal data or otherwise may cause us to incur significant costs for implementing lawful transfer 
mechanisms, conducting data transfer impact assessments, and implementing additional measures where necessary to 
ensure that any personal data transferred are adequately protected in a manner essentially equivalent to the EEA. The 
GDPR provides different transfer mechanisms we can use to lawfully transfer personal data from the EU to countries 
outside the EU. An example is relying on adequacy decisions of the European Commission, such as the EU-U.S. Data 
Privacy Framework. In October 2022, President Biden issued an executive order to implement EU-U.S. data privacy 
safeguards. In July 2023, the European Commission adopted its adequacy decision for the EU-U.S. Data Privacy 
Framework. The adequacy decision concludes that the U.S. ensures an adequate level of protection, compared to that of 
the EU for personal data transferred from the EU to U.S. companies participating in the EU-U.S. Data Privacy 
Framework. The adequacy decision on the EU-U.S. Data Privacy Framework covers data transfers from any public or 
private entity in the EEA to U.S. companies participating in the EU-U.S. Data Privacy Framework. With the adoption of 
the adequacy decision, EU entities are able to transfer personal data to U.S. companies participating in the EU-U.S. Data 
Privacy Framework without having to put in place additional data protection safeguards. Another example of a lawful 
transfer mechanism is using the EU Standard Contractual Clauses as approved by the European Commission in June 
2021, which are the most common transfer mechanism used to transfer personal data out of the EU to controllers or 
processors outside the EEA that are not directly subject to the GDPR. In order to use the EU Standard Contractual Clauses 
mechanism, the exporter and the importer must ensure that the importer can guarantee an adequate level of personal data 
protection in the importing country that is essentially equivalent to that of the EEA. Compliance with EU data transfer 
obligations involves conducting transfer impact assessments, which includes documenting detailed analyses of data access 
and protection laws in the countries in which data importers are located, which can be costly and time-consuming. Data 
importers must also expend resources in analyzing their ability to comply with transfer obligations, including 
implementing new safeguards and controls to further protect personal data.
In addition, the privacy and data security landscape in the EU continues to remain in flux. Brexit has created 
uncertainty with regard to future data protection regulation in the UK. The European Commission has adopted an 

35
adequacy decision concerning the level of data protection in the UK. Personal data may now flow freely from the EEA to 
the UK; however, the European Commission may suspend the adequacy decision if it decides that the UK no longer 
provides for an adequate level of data protection.
Data protection authorities from the different EU Member States and the UK may interpret the GDPR and applicable 
related national laws differently, may impose additional requirements under local data protection laws, and amend or 
update local data protection laws. In addition, regulatory guidance on implementation and compliance practices may be 
updated or otherwise revised, which adds to the complexity of processing personal data in the EEA. Enforcement by 
European and UK regulators is generally active, and failure to comply with the GDPR or applicable Member State and/or 
UK local law may result in warnings, compliance orders and fines (including possible fines of up to 4% of global annual 
turnover for the preceding financial year or €20 million (whichever is higher) for the most serious infringements). The 
GDPR also confers a private right of action on data subjects and consumer associations to lodge complaints with data 
protection authorities, seek judicial remedies, and obtain compensation for damages resulting from violations of the 
GDPR.
Compliance with these privacy data protection laws and regulations is onerous, constantly evolving, time 
consuming, and requires a flexible privacy framework and substantial resources. Compliance efforts will likely be an 
increasing and substantial cost in the future. We may be required to expend significant capital and other resources to 
ensure ongoing compliance with applicable privacy and data protection laws, to protect against security incidents, or to 
alleviate issues caused by such incidents. In addition, if our efforts to comply with applicable privacy and data protection 
laws and regulations are not successful, it could adversely affect our business. Failure to comply with such laws and 
regulations could result in government enforcement actions and create liabilities, including but not limited to imposition 
of significant penalties, private litigation (including class actions) and/or adverse publicity that could negatively affect our 
business.
Regulation in the Rest of the World
For other countries outside of the U.S., UK and EU, such as countries in Eastern Europe, Latin America or Asia, the 
requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary from country to 
country. In all cases, the clinical trials must be conducted in accordance with GCP requirements and the applicable 
regulatory requirements and the ethical principles that have their origin in the Declaration of Helsinki.
Approval by a regulatory authority in one jurisdiction does not guarantee approval by comparable regulatory 
authorities in other jurisdictions. If we fail to comply with applicable foreign regulatory requirements applicable to a 
given country, we may not be able to obtain regulatory approval for our product candidates in such country if we choose 
to seek such approval, or we may be subject to, among other things, fines, suspension or withdrawal of regulatory 
approvals, product recalls, seizure of products, operating restrictions and criminal prosecution.
Coverage and Reimbursement
U.S. Healthcare Reform
The containment of healthcare costs continues to remain a priority of federal and state governments, and the prices 
of drugs have been a focus in recent efforts. Changes in government legislation or regulation and changes in governmental 
health benefit programs’ or commercial payors’ policies governing reimbursement for our products, if successfully 
developed and approved, may reduce reimbursement of our products’ costs to physicians, pharmacies, patients, and 
distributors. The U.S. federal government and state legislatures, as well as foreign governments have shown significant 
interest in implementing cost-containment programs, including price controls, restrictions on reimbursement and 
utilization management requirements, such as requirements for substitution of generic products or therapeutic equivalents. 
Adoption of price controls and cost-containment measures, and adoption of more restrictive policies in jurisdictions with 

36
existing controls and measures, could limit our net revenue and results for products, if any, we commercialize in the 
future. 
The pricing and reimbursement environment for our products may change in the future and become more 
challenging due to state and federal healthcare reform measures. The American Recovery and Reinvestment Act of 2009, 
or ARRA, for example, allocated new federal funding to compare the effectiveness of different treatments for the same 
condition. The plan for the research was published in 2012 by HHS, the Agency for Healthcare Research and Quality and 
the National Institutes for Health, and periodic reports on the status of the research and related expenditures are made to 
Congress. Although ARRA does not mandate the use of the results of comparative effectiveness studies for 
reimbursement purposes, it is not clear what effect, if any, the research will have on the sales of any products for which 
we receive marketing approval or on the reimbursement policies of public and private payors. It is possible that 
comparative effectiveness research demonstrating benefits in a competitor’s product could adversely affect the sales of 
any product for which we receive marketing approval. For example, if third-party payors find our products not to be cost-
effective compared to other available therapies, they may not cover our products after approval as a benefit under their 
plans or, if they do, the level of payment may not be sufficient to allow us to sell our products on a profitable basis.
The ACA was a sweeping measure intended to expand healthcare coverage within the U.S., primarily through the 
imposition of health insurance mandates on employers and individuals, the provision of subsidies to eligible individuals 
enrolled in plans offered on the health insurance exchanges, and the expansion of the Medicaid program. This law has 
substantially changed the way healthcare is financed by both governmental and private insurers and has significantly 
impacted the pharmaceutical industry. Changes that may affect our business include those governing enrollment in federal 
healthcare programs, reimbursement changes, rules regarding prescription drug benefits under the health insurance 
exchanges, changes to the Medicaid Drug Rebate Program, expansion of the Public Health Service Act’s 340B drug 
pricing program, or 340B program, and fraud and abuse enforcement. Further changes made by the ACA include those to 
the Medicare Part D program establishing benefits for patients within a coverage gap in the Medicare Part D prescription 
drug program (commonly known as the “donut hole”), which was subsequently modified by the Inflation Reduction Act 
(as outlined below).These changes have impacted previously existing government healthcare programs and have resulted 
in the development of new programs, including Medicare payment for performance initiatives and improvements to the 
Medicare physician quality reporting system and feedback program.
One of the goals of ACA was to expand coverage for the uninsured while at the same time containing overall 
healthcare costs. With regard to pharmaceutical products, among other things, the ACA increased minimum rebates a 
manufacturer must pay under the Medicaid Drug Rebate Program and extended manufacturers’ Medicaid rebate liability 
to drugs dispensed to individuals who are enrolled in Medicaid managed care organizations. The ACA also requires 
manufacturers of drugs, devices, biologics, and medical supplies for which payment is available under Medicare, 
Medicaid or CHIP (with certain exceptions) to report annually to CMS information related to direct or indirect payments 
and other transfers of value to physicians and teaching hospitals, as well as ownership and investment interests held in the 
company by physicians and their immediate family members. Since 2022, applicable manufacturers also are required to 
report information regarding payments and transfers of value provided to physician assistants, nurse practitioners, clinical 
nurse specialists, certified nurse anesthetists, and certified nurse-midwives. Failure to submit required information may 
result in civil monetary penalties of $1,000 to $10,000 for each payment or ownership interest that is not timely, 
accurately, or completely reported (annual maximum of $150,000), and $10,000 to $100,000 for each knowing failure to 
report (annual maximum of $1 million). 
Some states have elected not to expand their Medicaid programs by raising the income limit to 133% of the federal 
poverty level for the ACA expansion population, as is permitted under the ACA. For each state that does not choose to 
expand its Medicaid program, there may be fewer insured patients overall, which could impact sales of our products that 
are approved and that we successfully commercialize, and our business and financial condition. Where Medicaid patients 
receive insurance coverage under any of the new options made available through the ACA, the possibility exists that 
manufacturers may be required to pay Medicaid rebates on drugs used under these circumstances, a decision that could 
impact manufacturer revenues.
Certain provisions of the ACA have been subject to judicial challenges as well as efforts to modify them or to alter 
their interpretation or implementation. For example, the U.S. Tax Cuts and Jobs Act of 2017 included a provision 

37
repealing the tax-based shared responsibility payment imposed by the ACA 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.” We expect 
that the ACA, its implementation, efforts to challenge or modify the ACA or its implementing regulations, or portions 
thereof, and other healthcare reform measures that may be adopted in the future, could have a material adverse effect on 
our industry generally and on our ability to commercialize our product candidates, if approved.
Other legislative changes relating to reimbursement have been adopted in the U.S. since the ACA was enacted. For 
example, the Budget Control Act of 2011, among other things, created the Joint Select Committee on Deficit Reduction to 
recommend to Congress proposals for spending reductions. The Joint Select Committee did not achieve a targeted deficit 
reduction, which triggered the legislation’s automatic reductions. In concert with subsequent legislation, this has resulted 
in aggregate reductions to Medicare payments to providers of, on average, 2% per fiscal year through 2030 (with the 
exception of a temporary suspension from May 1, 2020 through March 31, 2022, due to the COVID-19 pandemic). In 
December 2021, President Biden signed a law that provided for 1% Medicare sequestration in the second quarter of 2022 
and the full 2% sequestration thereafter until 2030.This sequestration is currently set at 2% and will increase to 2.25% for 
the first half of fiscal year 2030, to 3% for the second half of fiscal year 2030, and to 4% for the remainder of the 
sequestration period that lasts through the first six months of fiscal year 2031. As long as these cuts remain in effect, they 
could adversely impact payment for any products we may commercialize in the future. We expect that additional federal 
healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state 
governments will pay for healthcare products and services, and in turn could significantly reduce the projected value of 
certain development projects and reduce our profitability.
Further, the Inflation Reduction Act of 2022, or IRA, among other things, established a Medicare Part B inflation 
rebate scheme, under which, generally manufacturers will owe rebates if the average sales price of a Part B drug increases 
faster than the pace of inflation. Failure to timely pay a Part B inflation rebate is subject to a civil monetary penalty. The 
IRA also establishes a Medicare Part D inflation rebate scheme, under which generally manufacturers will owe rebates if 
the average manufacturer price of a Part D drug increases faster than the pace of inflation. The IRA also creates a drug 
price negotiation program under which the prices for Medicare units of certain high Medicare spend drugs and biologics 
without generic or biosimilar competition will be capped by reference to, among other things, a specified non-federal 
average manufacturer price, starting in 2026. Failure to comply with requirements under the drug price negotiation 
program is subject to an excise tax and/or a civil monetary penalty. The IRA further makes several changes to the 
Medicare Part D benefit, including a limit on annual out-of-pocket costs, and replacement of the coverage gap discount 
program with a new manufacturer discount program beginning in 2025, under which manufacturers are, in general, to 
provide a 10% discount on a covered Part D drug where a beneficiary is in the initial phase of Part D coverage and a 20% 
discount where a beneficiary is in the catastrophic phase of Part D coverage. Congress continues to examine various 
policy proposals that may result in pressure on the prices of prescription drugs in the government health benefit programs. 
The IRA or other legislative change could impact the market conditions for our product candidates.
Additional legislative changes, regulatory changes, or guidance could be adopted, which may impact potential 
marketing approvals and reimbursement for our product candidates, if approved. For example, there has been increasing 
legislative, regulatory, and enforcement interest in the U.S. with respect to drug pricing practices. There have been several 
Congressional inquiries and proposed and enacted federal and state legislation and regulatory initiatives designed to, 
among other things, bring more transparency to product pricing, evaluate the relationship between pricing and 
manufacturer patient programs, and reform government healthcare program reimbursement methodologies for drug 
products. Individual states in the U.S. have also increasingly passed legislation and implemented regulations designed to 
control pharmaceutical and biological product pricing, including by requiring pharmaceutical manufacturers to report to 
state agencies when they introduce new drugs to market with prices over a certain threshold, or when they increase the 
price of a drug over a certain threshold. Additionally, some individual states have begun establishing Prescription Drug 
Affordability Boards, or PDABs, to conduct affordability reviews for certain drugs, including high cost drugs and drugs 
with qualifying price increases. In some of these states, the PDAB has authority to set upper payment limits on what 
certain purchasers and payers may pay or reimburse for drugs that are found to pose an affordability challenge in the state. 
If healthcare policies or reforms intended to curb healthcare costs are adopted, the prices that we charge for any approved 
products may be limited, our commercial opportunity may be limited and/or our revenues from sales of our product and 
any future products, if approved, may be negatively impacted.
It is possible that the above-mentioned measures, as currently enacted or may be amended in the future, as well as 
other healthcare reform measures that may be adopted in the future, may result in additional reductions in Medicare and 

38
other healthcare funding, more rigorous coverage criteria, and new payment methodologies and additional downward 
pressure on coverage and payment and the price that we receive for any approved product. Any reduction in 
reimbursement from Medicare or other government programs may result in a similar reduction in payments from private 
payors. The implementation of additional cost containment measures or other healthcare reforms may prevent us from 
being able to generate revenue, attain profitability or commercialize our products. We cannot be sure whether additional 
legislative changes will be enacted in the U.S. or outside of the U.S., or whether regulatory changes, guidance or 
interpretations will be changed, or what the impact of such changes on our product candidates, if any, may be.
Pharmaceutical Pricing and Reimbursement
Sales of ZURZUVAE and any product candidates we successfully develop in the future depend on the availability 
and extent of coverage and reimbursement from third-party payors, which are increasingly reducing reimbursements for 
medical products and services. Decreases in third-party reimbursement for our products or a decision by a third-party 
payor not to cover a product or to manage utilization by, for example, requiring prior authorization or step edits, could 
reduce physician usage of our products and have a material adverse effect on our sales, results of operations and financial 
condition. In the U.S., healthcare professionals are reimbursed for covered services and products through Medicare, 
Medicaid, and other government healthcare programs, as well as through commercial insurance and managed healthcare 
organizations. Additional legislative changes, regulatory changes, or guidance could be adopted that may impact coverage 
and reimbursement for our products. For example, effective in April 2022, Congress expanded the availability of 
postpartum coverage under Medicaid and CHIP.
No uniform policy of coverage and reimbursement for drug products exists. Further, a payor’s decision to provide 
coverage for a drug product does not imply that an adequate reimbursement rate will be set because the process for 
determining whether a third-party payor will provide coverage for a drug product may be separate from the process for 
determining the reimbursement amount for the drug product. Accordingly, decisions regarding the extent of coverage and 
amount of reimbursement to be provided for any of our products will each be made on a payor-by-payor basis. 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.
We participate in the Medicaid Drug Rebate Program and other governmental programs. The Medicaid Drug Rebate 
Program and other governmental programs impose obligations to report certain pricing data to the federal government as 
well as other compliance obligations. Other programs impose limits on the price we are permitted to charge certain 
entities for our products. Statutory and regulatory changes or other agency action regarding these programs and their 
requirements could negatively affect the coverage and reimbursement by these programs of our products for which we 
receive regulatory approval and could negatively impact our results of operations or expand our rebate liability. 
Under the Medicaid Drug Rebate Program, we are required to pay a rebate to each state Medicaid program for our 
covered outpatient drugs that are dispensed to Medicaid beneficiaries and paid for by a state Medicaid program as a 
condition of having federal funds being available for our drugs under Medicaid and Medicare Part B. Those rebates are 
based on pricing data we report on a monthly and quarterly basis to CMS, the federal agency that administers the 
Medicare and Medicaid programs. These data include the average manufacturer price and, in the case of innovator 
products, the best price for each drug, which, in general, represents the lowest price available from the manufacturer to 
any wholesaler, retailer, provider, health maintenance organization, nonprofit entity, or governmental entity in the U.S. in 
any pricing structure, calculated to include all sales and associated rebates, discounts, and other price concessions. Where 
our average manufacturer price increases faster than the pace of inflation, we may be subject to an additional rebate in the 
amount that our average manufacturer price has exceeded the pace of inflation. As of January 1, 2024, there is no longer a 
cap on the rebate amount, and our rebate liability could increase accordingly.

39
The ACA made significant changes to the Medicaid Drug Rebate Program, and CMS issued a final regulation to 
implement the changes to the Medicaid Drug Rebate Program under the ACA. CMS also issued a final regulation that 
modified prior Medicaid Drug Rebate Program regulations to permit reporting multiple best price figures with regard to 
value-based purchasing arrangements; and provide definitions for “line extension,” “new formulation,” and related terms, 
with the practical effect of expanding the scope of drugs considered to be line extensions that are subject to an alternative 
rebate formula. Our failure to comply with these price reporting and rebate payment options could negatively impact our 
financial results. In September 2024, CMS further modified the regulations governing the Medicaid Drug Rebate 
Program, which could increase our costs and the complexity of compliance, impact rebate liabilities, and be time-
consuming to implement.
Federal law requires that any company that participates in the Medicaid Drug Rebate Program also participate in the 
340B drug pricing program in order for federal funds to be available for the manufacturer’s drugs under Medicaid and 
Medicare Part B. The 340B program, which is administered by the Health Resources and Services Administration, or 
HRSA, requires participating manufacturers to agree to charge statutorily defined covered entities no more than the 340B 
“ceiling price” for the manufacturer’s covered outpatient drugs. These 340B covered entities include a variety of 
community health clinics and other entities that receive health services grants from the Public Health Service, as well as 
hospitals that serve a disproportionate share of low-income patients. The ACA expanded the list of covered entities to 
include certain free-standing cancer hospitals, critical access hospitals, rural referral centers and sole community hospitals, 
but exempts “orphan drugs” from the ceiling price requirements for these covered entities. The 340B ceiling price is 
calculated using a statutory formula, which is based on the average manufacturer price and rebate amount for the covered 
outpatient drug as calculated under the Medicaid Drug Rebate Program, and, in general, products subject to Medicaid 
price reporting and rebate liability are also subject to the 340B ceiling price calculation and discount requirement. 
Changes to the definition of average manufacturer price and the Medicaid Drug Rebate amount also could affect our 340B 
ceiling price calculations and negatively impact our results of operations.
HRSA issued a final regulation regarding the calculation of the 340B ceiling price and the imposition of civil 
monetary penalties on manufacturers that are found to have knowingly and intentionally overcharged covered entities. It is 
unclear how HRSA will apply its enforcement authority under the regulation. We also are required to report our 340B 
ceiling prices to HRSA on a quarterly basis, and HRSA then publishes them to covered entities. Moreover, via final 
regulation, HRSA established an administrative dispute resolution, or ADR, process for claims by covered entities that a 
manufacturer has engaged in overcharging, and by manufacturers that a covered entity violated the prohibitions against 
diversion or duplicate discounts. Such claims are to be resolved through an ADR panel of government officials rendering 
a decision that could be appealed in federal court. HRSA issued a final rule that, effective June 2024, modified aspects of 
the ADR process, which could impact the procedures that are used to determine whether we owe additional 340B 
discounts. An ADR proceeding could subject a manufacturer to onerous procedural requirements and result in additional 
liability.
Federal law also requires all manufacturers to report the average sales price for drugs payable under the Medicare 
Part B program regardless of whether they are enrolled in the Medicaid Drug Rebate Program. Manufacturers calculate 
the average sales price based on a statutorily defined formula as well as regulations and interpretations of the statute by 
CMS. CMS uses these submissions to determine payment rates for drugs under Medicare Part B. Starting in 2023, 
manufacturers must pay refunds to Medicare for single source drugs or biologics, or biosimilar biological products, 
reimbursed under Medicare Part B and packaged in single-dose containers or single-use packages, for units of discarded 
drug reimbursed by Medicare Part B in excess of 10 percent of total allowed charges under Medicare Part B for that drug. 
Manufacturers that fail to pay refunds could be subject to civil monetary penalties of 125% of the refund amount.
Statutory or regulatory changes or CMS guidance could affect the average sales price calculations for our approved 
products and the resulting Medicare payment rate, and could negatively impact our results of operations. Also, the 
Medicare Part B drug payment methodology is subject to change based on legislation enacted by Congress. 
Congress also could enact additional changes that affect our overall rebate liability and the information we report to 
the government as part of price reporting calculations, which could impact the market conditions for our products. We 
further expect continued scrutiny on government price reporting and pricing more generally from Congress, agencies, and 

40
other bodies, and are seeing an increase in state interest in price reporting, transparency, and other policies to address drug 
pricing concerns.
Pricing and rebate calculations vary among products and programs. The calculations are complex and are often 
subject to interpretation by us, governmental or regulatory agencies and the courts. The Medicaid rebate amount will be 
computed each quarter based on our submission to CMS of our current average manufacturer prices and best prices for the 
quarter. If we become aware that our Medicaid reporting for a prior period was incorrect, or has changed as a result of 
recalculation of the pricing data, we are obligated to resubmit the corrected data for a period not to exceed three years 
from the period in which the data originally were due. Such restatements and recalculations would increase our costs for 
complying with the laws and regulations governing the Medicaid Drug Rebate Program. Any corrections to our rebate 
calculations could result in an overage or underage in our rebate liability for past quarters, depending on the nature of the 
correction. Price recalculations also may affect the ceiling price at which we are required to offer our products to covered 
entities under the 340B program, and may require us to issue refunds to 340B covered entities, which can be costly and 
burdensome.
Further, the IRA establishes Medicare Part B and Part D inflation rebate schemes (the first Part B inflation rebate 
period was in the first quarter of 2023; the first Part D inflation rebate period was in the fourth quarter of 2022 through the 
third quarter of 2023) and a drug price negotiation program, with the first negotiated prices to take effect in 2026. It also 
makes several changes to the Medicare Part D benefit, including the creation of a new manufacturer discount program in 
place of the current coverage gap discount program (beginning in 2025). Manufacturers may be subject to civil monetary 
penalties for certain violations of the negotiation and inflation rebate provisions and an excise tax during a noncompliance 
period under the negotiation program. Drug manufacturers may also be subject to civil monetary penalties with respect to 
their compliance with the new Part D manufacturer drug discount program.
We could be held liable for errors associated with our submission of pricing data. Civil monetary penalties can be 
applied if we are found to have made a misrepresentation in the reporting of our average sales price for each 
misrepresentation and for each day in which the misrepresentation was applied, or if we are found to have charged 340B 
covered entities more than the statutorily mandated ceiling price. In addition to retroactive rebates and the potential for 
340B program refunds, if we are found to have knowingly submitted false average manufacturer price or best price 
information to the government, or to have misrepresented that information, we may be liable for significant civil monetary 
penalties per item of false information. Our failure to submit monthly/quarterly average manufacturer price and best price 
data on a timely basis could result in a significant civil monetary penalty per day for each day the information is late 
beyond the due date. Such failures also could be grounds for CMS to terminate our Medicaid drug rebate agreement, 
pursuant to which we participate in the Medicaid program, or, if we fail to comply with 340B program requirements, 
HRSA could decide to terminate our 340B program participation agreement. In the event that CMS terminates our rebate 
agreement or HRSA terminates our 340B program participation agreement, no federal payments would be available under 
Medicaid or Medicare Part B for our covered outpatient drugs.
CMS and the Office of Inspector General have pursued manufacturers that were alleged to have failed to report these 
data to the government in a timely manner. Governmental agencies may also make changes in program interpretations, 
requirements or conditions of participation, some of which may have implications for amounts previously estimated or 
paid. We cannot guarantee that our submissions will not be found by CMS to be incomplete or incorrect. 
In order to be eligible to have our products paid for with federal funds under the Medicaid and Medicare Part B 
programs and purchased by the Department of Veterans Affairs, or VA, Department of Defense, or DoD, Public Health 
Service, and Coast Guard (collectively, the Big Four agencies) and certain federal grantees, we are required to participate 
in the VA Federal Supply Schedule, or FSS, pricing program, established under Section 603 of the Veterans Health Care 
Act of 1992. Under this program, we are obligated to make our “covered” drugs (i.e., innovator drugs and biologics) 
available for procurement on an FSS contract and charge a price to the Big Four agencies that is no higher than the 
Federal Ceiling Price, or FCP, which is a price calculated pursuant to a statutory formula. The FCP is derived from a 
calculated price point called the “non-federal average manufacturer price”, or Non-FAMP, which we are required to 
calculate and report to the VA on a quarterly and annual basis. Pursuant to applicable law, knowing provision of false 
information in connection with a Non-FAMP filing can subject a manufacturer to significant civil monetary penalties for 
each item of false information. The FSS contract also contains extensive disclosure and certification requirements. In 

41
addition, Section 703 of the National Defense Authorization Act for FY 2008, requires us to pay quarterly rebates to DoD 
on utilization of covered drugs that are dispensed through DoD’s Tricare network pharmacies to Tricare beneficiaries. The 
rebates are calculated as the difference between the annual Non-FAMP and FCP for the calendar year that the product was 
dispensed. If we overcharge the government in connection with the FSS contract or Tricare Retail Pharmacy Rebate 
Program, whether due to a misstated FCP or otherwise, we will be required to refund the difference to the government. 
Failure to make necessary disclosures and/or to identify contract overcharges can result in allegations against us under the 
False Claims Act and other laws and regulations. Unexpected refunds to the government, and any response to government 
investigation or enforcement action, would be expensive and time-consuming, and could have a material adverse effect on 
our business, financial condition, results of operations and growth prospects.
In addition, in many foreign countries, the proposed pricing for a drug must be approved before it may be lawfully 
marketed. The requirements governing drug pricing vary widely from country to country. For example, the EU Member 
States have the power to restrict the range of medicinal products for which their national health insurance systems provide 
reimbursement and to control the prices of medicinal products for human use. An EU Member State may approve a 
specific price for the medicinal product or it may instead adopt a system of direct or indirect controls on the profitability 
of the company placing the medicinal product on the market. There can be no assurance that any country that has price 
controls or reimbursement limitations for pharmaceutical products will allow favorable reimbursement and pricing 
arrangements for any of our products, if approved. Historically, products launched in the EU do not follow price structures 
of the U.S., and generally prices tend to be significantly lower.
In various EU Member States, we expect to be subject to continuous cost-cutting measures, such as lower maximum 
prices, lower or lack of reimbursement coverage and incentives to use cheaper, usually generic, products as an alternative. 
Health Technology Assessment, or HTA, of medicinal products is becoming an increasingly common part of the pricing 
and reimbursement procedures in some EU Member States, including countries representing major markets. The HTA 
process, which is governed by the national laws of these countries, is the procedure according to which the assessment of 
the public health impact, therapeutic impact and the economic and societal impact of use of a given medicinal product in 
the national healthcare systems of the individual country is conducted. The outcome of HTA regarding specific medicinal 
products will often influence the pricing and reimbursement status granted to these medicinal products by the competent 
authorities of individual EU Member States. On January 31, 2018, the European Commission presented a proposal for a 
regulation on health technologies assessment. The proposal was adopted in December 2021 and will apply as of January 
2025. This EU HTA regulation is intended to boost cooperation among EU Member States in assessing health 
technologies, including new medicinal products, and providing the basis for cooperation at the EU level for joint clinical 
assessments in these areas.

Item 1A. Risk Factors 
Investing in our common stock involves a high degree of risk. You should carefully consider the risks described 
below, as well as the other information in this Annual Report on Form 10-K, or Annual Report, and in our other public 
filings before making an investment decision. Our business, prospects, financial condition, or operating results could be 
harmed by any of these risks, as well as other risks not currently known to us or that we currently consider immaterial. If 
any such risks or uncertainties actually occur, our business, financial condition or operating results could differ 
materially from the plans, projections and other forward-looking statements included in this Annual Report, including in 
the foregoing Business section and later in the section titled “Management’s Discussion and Analysis of Financial 
Condition and Results of Operations” and elsewhere in this report and in our other public filings and public statements. 
The trading price of our common stock could decline due to any of these risks, and as a result, our stockholders may lose 
all or part of their investment. 
Risks Related to Product Development, Regulatory Approval and Commercialization
Our future business prospects depend heavily on our ability, with our collaboration partner, Biogen MA Inc., and 
Biogen International GmbH, or together, Biogen, to successfully commercialize ZURZUVAE® (zuranolone) for the 
treatment of women with postpartum depression, or PPD, in the U.S. There is no assurance that our commercialization 
efforts in the U.S. with respect to ZURZUVAE for the treatment of women with PPD will be successful or that we will 
be able to generate revenues at the levels or on the timing we expect or at levels or on the timing necessary to support 
our goals.
Our business currently depends heavily on our ability, along with our collaboration partner, Biogen, to successfully 
continue to commercialize ZURZUVAE in the U.S. as a treatment for women with PPD. ZURZUVAE was approved by 
the United States Food and Drug Administration, or FDA, in August 2023 as a treatment for adults with PPD and became 
commercially available in the U.S. in December 2023. ZURZUVAE is the first oral treatment specifically indicated for 
adults with PPD. We may never be able to successfully commercialize ZURZUVAE or meet our expectations with 
respect to revenues or profits from sales. ZURZUVAE may not achieve, or, even if achieved, maintain, broad market 
acceptance. Healthcare professionals may decide not to use ZURZUVAE as a treatment option for their patients with PPD 
or may only consider prescribing ZURZUVAE for a subset of women with PPD in their practice who they consider to 
have particularly severe symptoms relative to other patients suffering from this disease. ZURZUVAE may not achieve 
brand awareness and adoption among healthcare professionals, including OBGYNs, and our beliefs about the potential for 
OBGYNs to utilize ZURZUAVE at the forefront of postpartum care may prove to be incorrect. ZURZUVAE also may 
not achieve or, even if achieved, maintain broad market acceptance from women with PPD who may decide that they do 
not want to be treated with ZURZUVAE out of concerns about the safety and tolerability profile of ZURZUVAE or use 
while breastfeeding. ZURZUVAE includes a boxed warning that instructs healthcare professionals to advise patients that 
ZURZUVAE causes driving impairment due to central nervous system depressant effects, and that people who take 
ZURZUVAE should not drive a motor vehicle or engage in other potentially hazardous activities requiring complete 
mental alertness until at least 12 hours after ZURZUVAE administration for the duration of the once-daily 14-day 
treatment course, which could decrease willingness to prescribe or use ZURZUVAE. The label also includes information 
about adverse events and other warnings and precautions that may cause a woman with PPD not to consider ZURZUVAE 
as a treatment option. 
ZURZUVAE also may not achieve or, even if achieved, maintain broad market acceptance for the treatment of 
women with PPD if payors are not willing to provide reimbursement for the treatment or impose significant restrictions on 
reimbursement. Payors that currently have favorable coverage for ZURZUVAE in PPD may change their policies and 
may decide to limit reimbursement for ZURZUVAE, including by requiring women with PPD to try other treatments 
prior to ZURZUVAE, requiring a specific showing of symptom severity on measurements scales, requiring prior 
consultation with a psychiatrist or other specialist, or imposing other onerous prior authorization requirements, or may 
deny reimbursement for other reasons or in all cases. Some payors currently require that healthcare professionals attest 
that the women with PPD for whom they have prescribed ZURZUVAE have severe symptoms. In addition, even if a 
healthcare professional writes a prescription for ZURZUVAE for the treatment of a woman with PPD, the prescription 
may not result in product being shipped to the patient and/or the patient taking ZURZUVAE. The healthcare professional 
or the patient may, for example, not take the steps necessary to obtain reimbursement or to have the prescription filled at 

45
the specialty pharmacy or may find the process of obtaining a prescription through the specialty pharmacy too slow or 
complicated. There is no guarantee that the infrastructure, systems, processes, policies, relationships and materials we and 
Biogen have built for the commercialization of ZURZUVAE for the treatment of women with PPD in the U.S. will be 
sufficient for us to achieve or, even if achieved, maintain success. ZURZUVAE may also not achieve the clinical benefit 
we expect in women with PPD. Our commercialization of ZURZUVAE in PPD may be negatively impacted by 
competition from other drugs currently on the market or that may be approved in the future. The number of women with 
PPD, the unmet need for additional treatment options for women with PPD, and the potential market for ZURZUVAE 
may be significantly smaller than we expect, or we may encounter other market-related issues in the commercialization of 
ZURZUVAE for the treatment of women with PPD, including as a result of the price we charge. We and our collaboration 
partner, Biogen, may not be applying the optimal resources to the launch of ZURZUVAE or we or Biogen may not be 
able or willing to scale our resources at the right time or at an effective level. Even if we are successful in 
commercializing ZURZUVAE for the treatment of women with PPD, we expect the revenues from ZURZUVAE for the 
treatment of women with PPD will be significantly lower than if we had received regulatory approval in major depressive 
disorder, or MDD. 
Our plans to explore strategic alternatives and our rejection of an unsolicited, non-binding acquisition proposal from 
Biogen to acquire all of our outstanding shares not owned by Biogen may have a material adverse effect on our 
business. 
On January 10, 2025, we received an unsolicited, non-binding acquisition proposal from Biogen to acquire all of our 
outstanding shares not owned by Biogen for $7.22 per share, or the Biogen Proposal. On January 27, 2025, we announced 
that our Board of Directors has initiated a process to explore strategic alternatives, and further announced that our Board 
of Directors unanimously rejected the Biogen Proposal. On January 16, 2025, we commenced litigation against Biogen 
Inc. and Biogen MA Inc., or together with Biogen Inc., Biogen, in the Delaware Court of Chancery seeking declaratory, 
injunctive and other relief. In our complaint, we alleged that Biogen breached the standstill provision in the stock 
purchase agreement we entered into with Biogen on November 27, 2020, or the Biogen Stock Purchase Agreement, by 
making an unsolicited acquisition proposal and related public disclosures. On this basis, we also sought a temporary 
restraining order enjoining Biogen from future breaches of the standstill provision. At a hearing held on January 28, 2025, 
the Delaware Court of Chancery granted our motion for a temporary restraining order against Biogen MA Inc., and 
entered an implementing order on January 30, 2025, or the TRO Order. Pursuant to the TRO Order, unless consented to 
by Sage in writing or otherwise ordered by the court, Biogen MA Inc. and its directors, officers, agents, employees, 
attorneys, representatives, persons in active concert or participation with it, and anyone acting under its direction or 
control are enjoined from taking any action inconsistent with the Biogen Stock Purchase Agreement’s contractual 
prohibitions against (i) making a public acquisition proposal, (ii) making a private acquisition proposal that is reasonably 
expected to require public disclosure, or (iii) publicly encouraging any acquisition proposal. Our rejection of the Biogen 
Proposal, our efforts to enforce the terms of the Biogen Stock Purchase Agreement and our strategic review process may 
adversely impact our relationship with Biogen, including our efforts to commercialize ZURZUVAE. We cannot be certain 
that our efforts to date with Biogen, including regarding sales force coordination, engagement with payors, and education 
efforts related to PPD will not be adversely impacted or that Biogen will continue to make investments related to 
ZURZUVAE. Any disruption of our relationship with Biogen under our collaboration agreement with Biogen may have 
an adverse impact on sales of ZURZUVAE, which may in turn materially adversely affect our business, results of 
operations, financial condition and prospects. We have not set a timetable for the strategic review process, nor have we 
made any decisions related to any potential strategic alternatives at this time. There can be no assurance that our strategic 
review process will result in any transaction or other strategic outcome. We do not intend to disclose further developments 
on this strategic review process unless and until we determine that such disclosure is appropriate or necessary. If we 
determine to engage in a transaction as a result of our exploration and evaluation of strategic alternatives, our future 
business, prospects, financial position and operating results could be significantly different than those in historical periods 
or projected by our management. 
Our future business prospects depend heavily on our ability, alone or through our collaborations, to successfully 
develop, gain regulatory approval of and commercialize our current and future product candidates. We cannot be 
certain that we will be able to initiate planned clinical trials, to complete ongoing clinical trials or to announce results 
of such trials with respect to any of our product candidates, on the timelines we expect or at all, or that the results of 
our clinical trials or other activities under our development programs will be positive. We cannot be certain that we or 

46
our collaborators will be able to advance such product candidates into additional trials or to successfully develop, 
obtain regulatory approval for, or successfully commercialize any such product candidates, if approved.
Our future business prospects depend heavily on our ability, alone or through our collaborations, to successfully 
develop and gain regulatory approval of our current and future product candidates. Drug development and obtaining 
regulatory approval for a product involve a long, expensive and uncertain process, involving a high degree of risk.
Before obtaining regulatory approvals for the commercial sale of any product candidate, non-clinical studies and 
clinical trials must demonstrate that the product candidate is safe and effective for use in each target indication. We or our 
collaborators, as applicable, may not be able to demonstrate the efficacy and safety of any of our current product 
candidates or any future product candidate at each stage of clinical development or we may encounter other issues with 
any clinical trials or non-clinical studies required for regulatory submissions. Some or all of our or our collaborators’ 
clinical trials may fail to meet their primary or key secondary endpoints, raise safety issues or generate mixed results.
For example, in July 2024, we announced that the KINETIC 2 Study, a Phase 2b dose-ranging clinical trial 
evaluating SAGE-324 for the treatment of patients with essential tremor, did not meet its primary or secondary 
endpoints. As a result, we and Biogen announced plans to close our ongoing open label safety study of SAGE-324 and to 
cease further clinical development of SAGE-324 in essential tremor. Subsequently, in September 2024, Biogen notified us 
of its termination of our collaboration agreement solely with respect to SAGE-324 on a worldwide basis, effective 
February 17, 2025. While we are evaluating next steps, if any, for other potential indications for SAGE-324, including 
seizures in developmental and epileptic encephalopathies, or DEEs, these efforts may be unsuccessful. We may choose 
not to further develop SAGE-324, or if we do study SAGE-324 in this or other indications, such efforts may result in 
significant expenditure of time and expense, and we may never achieve positive results from the SAGE-324 program or 
obtain approval by a regulatory authority. 
In addition, based on the results of the Phase 2 DIMENSION, LIGHTWAVE and PRECEDENT Studies evaluating 
dalzanemdor for the treatment of patients with cognitive impairment associated with Huntington’s disease, mild cognitive 
impairment and mild dementia due to Alzheimer’s disease, and cognitive impairment due to Parkinson’s disease, 
respectively, none of which met its primary endpoint, we do not plan to pursue further development of dalzanemdor.
Studying alternate formulations of our product candidates or doses that achieve higher or lower patient exposure 
may result in unexpected adverse events or raise other safety issues or may otherwise generate negative results. For 
example, in the KINETIC 2 Study, we evaluated multiple doses, including the same maximum dose of SAGE-324 that we 
evaluated in prior studies. SAGE-324 did not demonstrate a statistically significant dose-response relationship on the 
primary endpoint in participants with essential tremor. A dose-relationship was observed, however, in the incidence of 
central nervous system, or CNS, depressant treatment emergent adverse events, or TEAEs, and in the frequency of 
TEAEs, leading to study drug discontinuation. We might decide to evaluate different doses, formulations, and durations of 
dosing for any of our product candidates with other studies or programs in the future. Changes in formulation or the need 
to refine or scale-up the manufacturing process could also delay development or require us to conduct additional clinical 
trials or non-clinical studies or conduct post-approval analyses or could lead to different results.
We or our collaborators may not be able to initiate or complete our clinical trials or announce results from our 
clinical trials on the timelines we expect. We or our collaborators may experience slower than expected activation of sites 
or enrollment and randomization of patients in our clinical trials, particularly in clinical trials where an in-patient stay or 
frequent site visits are required, the patient population is small or otherwise difficult to enroll, enrollment criteria are more 
selective than historically used, there are existing therapies, where other companies are running large clinical trials, or 
where relevant clinical sites or our vendors are experiencing healthcare staffing shortages or significant turnover. There is 
also the potential for slower than expected clinical site initiation, problems with the conduct of a study at one or more 
sites, delays or problems in analyzing data, the potential need for additional analysis or data or the need to enroll 
additional patients, the negative impact of feedback from the FDA or other regulatory authorities on trial design or 
analysis of results, the need to make protocol amendments or other unexpected issues, such as adverse events, in any of 
our clinical trials. These types of delays or issues could lead to delays in the completion of a trial and announcement of 
results or impact the results of our trials.

47
Our ongoing and planned development activities may be negatively impacted by a number of factors. Widespread 
healthcare and vendor staffing shortages and increased competition for patients and clinical sites may make it difficult to 
enroll patients in our clinical trials and/or identify and activate participating clinical sites for our trials, may cause other 
delays at clinical trial sites and/or vendors, and may increase the rates of patients withdrawing from our clinical trials 
following enrollment. Some clinical sites may decline or delay participation in our trials due to capacity and resource 
constraints. These factors may substantially slow clinical site identification and activation and enrollment in our clinical 
trials, or cause us to pause trials, which may, in each case, significantly impact our ability to meet our expected timelines, 
budgets, or other plans. 
We or our clinical sites may in the future implement measures to help minimize the number of visits a clinical trial 
participant is required to make to a site in response to certain events, including by limiting or modifying clinical trial 
procedures and visits for data collection, or clinical sites may impose other restrictions or limitations on key clinical trial 
activities such as restrictions related to monitoring of the sites by clinical research organizations. Limitations or 
modifications to study procedures, study visits or data collection, restrictions on key clinical trial activities such as 
monitoring or auditing, or other restrictions that may affect data analysis activities may require additional assessment and 
evaluation from institutional review boards; negatively impact the integrity or completeness of our trial data, the powering 
of a trial, the integrity or relevance of clinical study endpoints; or impact the timing of availability of results.
The drug development process can take many years and may include post-marketing studies and surveillance, which 
will require the expenditure of substantial resources. Of the large number of drugs in development in the U.S., only a 
small percentage will successfully complete the FDA regulatory approval process and will be commercialized. 
Accordingly, even if we have the requisite financial resources, when needed, to continue to fund our development efforts, 
we cannot assure you that any of our current or future product candidates will be successfully developed or 
commercialized either in the U.S. or in any other country. Even if we or our collaborators conduct the trials required by or 
discussed with the FDA, the FDA may ultimately decide that the design, number and type of trials, number of patients 
studied or results, even if positive, are not sufficient to file for or gain regulatory approval of our product candidates in the 
indications we study, or do not support the safety, efficacy or intended profile for our product candidate, as was the case 
with the complete response letter, or CRL, that the FDA issued related to the new drug application, or NDA, for 
zuranolone for the treatment of MDD. 
We may never be able to generate meaningful revenues from sales of our current or future products at levels or on 
timing necessary to support our investment and goals, and we may ultimately decide to discontinue commercial 
availability of products that we are unable to successfully commercialize or as a result of market changes.
We are a commercial-stage company, selling ZURZUVAE in the U.S. market. Even if we or one of our 
collaborators gains approval of any of our current or future product candidates, we and our collaborators may never be 
able to successfully commercialize such new product in the approved indications or meet our expectations with respect to 
timing and revenues or profits from sales of such product. The lack of commercial success at levels or on timing necessary 
to support our investment and goals, or overall changes to the market, may lead us to discontinue a product and/or 
voluntarily request the withdrawal of a product’s NDA even if successfully developed and approved.
For example, we discontinued commercial availability of our product ZULRESSO® (brexanolone) CIV injection in 
the U.S. as of December 31, 2024. ZULRESSO was first made commercially available in the U.S. in June 2019. Since 
launch, our revenues from sales of ZULRESSO were negatively impacted by significant barriers arising from the complex 
requirements for treatment and, more recently, by the introduction of ZURZUVAE as a treatment for women with PPD. 
These requirements created significant barriers to treatment with ZULRESSO for women with PPD. 
We also encountered other issues and challenges in commercializing ZULRESSO and generating revenues, 
including:
•
Some women with PPD who needed treatment found it too onerous to undergo an infusion or to be treated at a 
certified healthcare setting overnight for the length of stay required for treatment, or to be enrolled in the 
registry that is part of the Risk Evaluation and Mitigation Strategy, or REMS, process or have been concerned 
about the risk of excessive sedation and sudden loss of consciousness. 

48
•
More healthcare professionals than we expected were unwilling to accept ZULRESSO as a treatment for 
women with PPD.
•
ZULRESSO competed with lower cost antidepressants.
•
Given the complex requirements for treatment, use of ZULRESSO in the U.S. was focused primarily on 
women with more severe symptoms of PPD.
•
We encountered coverage and reimbursement challenges, including restrictions related to the severity of PPD 
cases for which ZULRESSO would be reimbursed, requirements that other treatments be used prior to 
ZULRESSO, or other limitations in the scope, breadth, availability or amount of reimbursement covering 
ZULRESSO or the infusion.
•
A number of healthcare settings that were willing to administer ZULRESSO to women with PPD who had 
commercial insurance were not willing to treat Medicaid patients, which adversely affected our ability to 
generate revenue from ZULRESSO.
To the extent we face issues with current or future products that impact market acceptance, convenience, 
availability, reimbursement or other aspects of commercialization, as applicable, these issues could impair our ability to 
generate revenues or meet our expectations with respect to the amount or timing of revenues for our products. If we 
decide to discontinue commercial availability and/or voluntarily request the withdrawal of the NDA for any of our 
products as a result of such challenges, as we did with ZULRESSO, the withdrawal of the product from the marketplace 
may raise additional potential risks and uncertainties, including from contract terminations or other actions, including by 
regulatory authorities, which we may not be able to predict. Any issues or hurdles related to our commercialization efforts 
may materially adversely affect our business, results of operations, financial condition and prospects and could lead us to 
make significant further changes to the scope and nature of our efforts.
Any product or product candidate that we develop may cause undesirable side effects that limit their commercial 
profile; delay or prevent further development or regulatory approval; cause regulatory authorities to require labeling 
statements, such as a boxed warning or a REMS; or result in other negative consequences.
We may observe undesirable side effects or other potential safety issues in nonclinical studies, in clinical trials at 
any stage of development, as part of an expanded access program, in commercial use or in post-approval studies. Clinical 
trials by their nature utilize a sample of the potential patient population. With a limited number of patients and limited 
duration of exposure, certain side effects of ZURZUVAE, ZULRESSO, or any other product or product candidate that we 
may develop, may only be uncovered, or the frequency or severity identified, with a larger number of patients exposed to 
the product. Those side effects could be serious or life-threatening. If we or others identify any such undesirable side 
effects, or the increased severity or frequency of any known side effects:
•
regulatory authorities may withdraw, withhold or limit their approval of such products; 
•
the FDA or regulatory authorities outside the U.S. may impose a clinical hold or partial clinical hold which 
could cause us or our collaborators to have to stop, delay or restrict further development; 
•
we or our collaborators may, even without a clinical hold, decide to interrupt, delay or halt existing non-
clinical studies and clinical trials or stop development;
•
we may have difficulty enrolling patients in our clinical trials and completing such trials on the timelines we 
expect or at all, or we may have to conduct additional non-clinical studies or clinical trials as part of a 
development program; 
•
if an NDA for any of our product candidates is reviewed by an advisory committee of the FDA, the advisory 
committee may recommend against approval of the application or may recommend that the FDA require, as a 
condition of approval, additional non-clinical studies or clinical trials, limitations on approved labeling or 
distribution and use restrictions, and the FDA may ultimately agree with the recommendations of the advisory 
committee;

49
•
we or our collaborators may not be able ultimately to demonstrate, to the satisfaction of regulatory authorities, 
that our product candidates are safe and that the benefits outweigh the safety risks, and the applicable 
regulatory authorities may not approve the product candidate;
•
regulatory authorities may require the addition of labeling statements, such as a boxed warning or additions to 
an existing boxed warning, or a contraindication, including as a result of inclusion in a class of drugs for a 
particular disease, or may require a REMS, or modifications to an existing REMS;
•
we or our collaborators may be required to change the way such products are distributed or administered, 
conduct post-approval studies or change the labeling of the products;
•
we or our collaborators may be subject to regulatory investigations and government enforcement actions;
•
we or our collaborators may decide to remove such products from the marketplace;
•
we or our collaborators could be held liable for injury caused to individuals exposed to or taking our products 
or product candidates; and
•
our reputation may suffer.
We believe that any of these events could prevent us from achieving or maintaining market acceptance of the 
affected products, could substantially increase the risks to our business, including the risks and costs of developing our 
product candidates or commercializing our products, and could significantly adversely impact our ability and that of our 
collaborators to successfully develop, gain regulatory approval for, and commercialize our current product candidates or 
future products and generate revenues at the levels we expect, or at all.
Obtaining regulatory approval to market any of our product candidates is a complex, lengthy, expensive and uncertain 
process, and regulatory authorities may delay, limit or deny approval of any of our product candidates for many 
reasons. Any setback or delay in obtaining regulatory approval for any of our product candidates or in our, or our 
collaborators’, ability to commence or continue marketing of our products, if approved, may have a material adverse 
effect on our business and prospects.
We are not permitted to market any of our product candidates in the U.S. until we or our collaborators receive 
approval of an NDA from the FDA or in any foreign countries until we or our collaborators receive the requisite 
marketing approval from such countries. Obtaining approval of an NDA in the U.S. or marketing approval in any country 
outside the U.S. is a complex, lengthy, expensive and uncertain process. For example, on August 4, 2023, the FDA issued 
a CRL related to the NDA for zuranolone for the treatment of MDD. The CRL stated that the NDA did not provide 
substantial evidence of effectiveness to support the approval of zuranolone for the treatment of MDD and that one or more 
additional clinical trials would be needed. Regulatory authorities may delay, limit or deny approval of any of our product 
candidates for many reasons, including, among others:
•
we or our collaborators may not be able to demonstrate, to the satisfaction of regulatory authorities, that our 
product candidates are safe and effective in any indication, as was the case with respect to the NDA for 
zuranolone for the treatment of MDD, and that the benefits outweigh the safety risks;
•
the results of our non-clinical studies and clinical trials may be negative, or may not meet the level of statistical 
or clinical significance or other criteria required by regulatory authorities for marketing approval;
•
regulatory authorities may impose a clinical hold or partial clinical hold prior to the initiation of development 
or during development of our product candidates, which could cause us to have to stop, delay or restrict further 
development;
•
regulatory authorities may disagree with our interpretation of data from our non-clinical studies and clinical 
trials, or may not accept data generated at one or more of our sites conducting non-clinical studies or clinical 
trials which could cause the study or trial to fail;
•
regulatory authorities may determine that the number, design, size, conduct, implementation or results of our 
non-clinical studies or clinical trials are inadequate for regulatory approval or that changes in dosing or drug 
formulation used in our non-clinical studies or clinical trials require additional trials or studies, even if the 

50
regulatory authorities have previously reviewed and commented on the design and details of our plans, as was 
the case with respect to the NDA for zuranolone for the treatment of MDD;
•
regulatory or other governmental authorities may require that we or our collaborators conduct additional non-
clinical studies and clinical trials prior to approval or post-approval;
•
regulatory authorities may not approve the formulation, labeling or specifications of any of our product 
candidates;
•
if an NDA for any of our product candidates is reviewed by an advisory committee of the FDA, the advisory 
committee may recommend against approval of the application or may recommend that the FDA require, as a 
condition of approval, additional non-clinical studies or clinical trials, limitations on approved labeling or 
distribution and use restrictions, and the FDA may ultimately agree with the recommendations of the advisory 
committee;
•
regulatory authorities may approve a product candidate for which we or our collaborators are seeking 
regulatory approval for a more limited patient population than expected or with substantial use restrictions;
•
the FDA may require a REMS as a condition of approval or post-approval for our product candidates, as was 
the case with ZULRESSO, or may modify an existing REMS or may impose other limitations or restrictions, 
like a boxed warning, as is the case with ZURZUVAE;
•
regulatory authorities may determine that the manufacturing processes or facilities of third-party contract 
manufacturers with which we contract do not conform to applicable requirements, including cGMPs; or
•
regulatory authorities may change their approval policies or adopt new regulations.
Further, under the Pediatric Research Equity Act, or PREA, an NDA or supplement to an NDA for certain drugs 
must contain data to assess the safety and effectiveness of the drug in all relevant pediatric subpopulations and to support 
dosing and administration for each pediatric subpopulation for which the product is safe and effective, unless the sponsor 
receives a deferral or waiver from the FDA. A deferral may be granted for several reasons, including a finding that the 
product or therapeutic candidate is ready for approval for use in adults before pediatric trials are complete or that 
additional safety or effectiveness data needs to be collected before the pediatric trials begin. The law requires the FDA to 
send a PREA Non-Compliance letter to sponsors who have failed to submit their pediatric assessments required under 
PREA, have failed to seek or obtain a deferral or deferral extension or have failed to request approval for a required 
pediatric formulation. It further requires the FDA to publicly post the PREA Non-Compliance letter and sponsor’s 
response. The applicable legislation in the European Union, or EU, also requires sponsors to either conduct clinical trials 
in a pediatric population in accordance with a Pediatric Investigation Plan approved by the Pediatric Committee of the 
European Medicines Agency, or EMA, or to obtain a waiver or deferral from the conduct of these studies by this 
Committee. For any of our product candidates for which we or our collaborators are seeking regulatory approval in the 
U.S. or the EU, we cannot guarantee that we will be able to obtain a waiver or alternatively complete any required studies 
and other requirements in a timely manner, or at all, which could result in an issuance and publication of a PREA Non-
Compliance letter and associated reputational harm, our product candidate being considered misbranded and subject to 
relevant enforcement action, invalidation of the marketing application, and/or financial penalties. Our collaborators are 
also subject to similar requirements outside of the U.S. and EU and thus the attendant risks and uncertainties.
Any of these factors, many of which are beyond our control, could jeopardize or delay our or our collaborators’ 
ability to obtain regulatory approval for product candidates and successfully market approved products. Even if we or our 
collaborators receive marketing approval for any of our product candidates, regulatory or other governmental authorities 
may still impose significant restrictions, including restrictions on the indicated use or marketing, or may impose ongoing 
requirements for potentially costly post-approval studies. For example, the FDA imposed post-approval obligations in 
connection with approval of ZURZUVAE. For ZURZUVAE, the FDA is requiring two post-marketing studies: a 
pharmacokinetic and safety study in adolescent females who have completed puberty and an embryofetal toxicity study in 
a second species. Although we expect to complete these studies, we may not be able to fulfill these obligations in 
accordance with the FDA’s requirements, or at all. The FDA recommended controlled substance scheduling with respect 
to ZURZUVAE under the CSA, which ultimately received a Schedule IV classification from the DEA. The FDA may 
recommend scheduling with respect to any of our current or future product candidates, if approved. In such event, as was 
the case with ZURZUVAE and ZULRESSO, prior to a product launch, the DEA will need to determine the controlled 

51
substance schedule of the product, taking into account the recommendation of the FDA. The timing of the scheduling 
process would delay our ability to market any product candidate that is successfully developed and approved. In addition, 
the scheduling designation itself could impact the commercialization and market opportunity for any product candidate 
that is successfully developed and approved.
We may seek priority review of future NDA submissions with the FDA, if our development efforts with respect to 
any of our product candidates are successful, but the FDA may not grant such priority review. Even if the FDA grants 
priority review for an NDA, the FDA may not meet the applicable review timelines or may elect to extend the timeframe 
for their review. Delays, resource constraints, and other disruptions at the FDA and other authorities may slow the time 
necessary for new drugs to be reviewed and/or approved by necessary government authorities, which would adversely 
affect our business. 
Fast Track and Breakthrough Therapy designations from the FDA, PRIority Medicines, or PRIME, designation from 
the EMA, Innovative Licensing and Access Pathway designation from the Medicines & Healthcare products Regulatory 
Agency in the United Kingdom, or similar designations in other countries or regions do not necessarily lead to a faster 
development pathway or regulatory review process, and do not increase the likelihood of regulatory approval. For 
example, on August 4, 2023, the FDA issued a CRL related to the NDA for zuranolone for the treatment of MDD after 
previously granting both Fast Track and Breakthrough Therapy designations to zuranolone for MDD. The FDA may 
withdraw Fast Track designation or Breakthrough Therapy designation, and the EMA may withdraw PRIME designation, 
if the relevant agency believes that the designation is no longer supported by data from our clinical development 
programs. For example, in November 2023, the FDA rescinded Breakthrough Therapy Designation for zuranolone for the 
treatment of MDD. 
We or our collaborators may not be able to obtain orphan drug exclusivity for any product candidates we, or they, may 
develop. Even if we do, that exclusivity may not prevent the FDA or the EMA from approving other competing 
products.
Under the Orphan Drug Act, the FDA may designate a product as an orphan drug if it is a drug or biologic intended 
to treat a rare disease or condition. A similar regulatory scheme governs approval of orphan products by the EMA in the 
EU. Generally, if a product candidate with an Orphan Drug Designation subsequently receives the first marketing 
approval for the indication for which it has such designation, the product is entitled to a period of marketing exclusivity, 
which precludes the FDA or the EMA, as applicable, from approving another marketing application for the same product 
for the same therapeutic indication for that time period. The applicable period is seven years in the U.S. and ten years in 
the EU. The exclusivity period in the EU can be reduced to six years if a product no longer meets the criteria for Orphan 
Drug Designation, in particular, if the product is sufficiently profitable so that market exclusivity is no longer justified.
In order for the FDA to grant orphan drug exclusivity to one of our products, the Agency must find that the product 
is indicated for the treatment of a condition or disease with a patient population of fewer than 200,000 individuals 
annually in the U.S. The FDA may conclude that the condition or disease for which we seek orphan drug exclusivity does 
not meet this standard. Even if we obtain orphan drug exclusivity for a product, that exclusivity may not effectively 
protect the product from competition because different products can be approved for the same condition. In addition, even 
after an orphan drug is approved, a regulatory authority, such as the FDA and EMA, can subsequently approve the same 
product for the same condition if such regulatory authority concludes that the later product is clinically superior in that it 
is shown to be safer, more effective or makes a major contribution to patient care. Orphan drug exclusivity may also be 
lost if such regulatory authority determines that the request for designation was materially defective or if the manufacturer 
is unable to assure sufficient quantity of the product to meet the needs of the patients with the rare disease or condition.
The FDA and Congress may further reevaluate the Orphan Drug Act and its regulations and policies. This may be 
particularly true in light of a decision from the U.S. Court of Appeals for the Eleventh Circuit in September 2021 finding 
that, for the purpose of determining the scope of exclusivity, the term “same disease or condition” means the designated 
“rare disease or condition” and could not be interpreted by the FDA to mean the “indication or use.” Although there have 
been legislative proposals to overrule this decision, they have not been enacted into law. On January 23, 2023, the FDA 
announced that, in matters beyond the scope of that court order, the FDA will continue to apply its existing regulations 
tying orphan-drug exclusivity to the uses or indications for which the orphan drug was approved. 

52
We do not know if, when, or how the FDA or other regulatory agencies may change the orphan drug regulations and 
policies in the future or whether legislative action will be taken, and it is uncertain how any changes might affect our 
business. Depending on what changes the regulatory authorities or legislatures may make to orphan drug regulations and 
policies, our business could be adversely impacted.
The number of people with the diseases and disorders for which our products are indicated and for which our product 
candidates are targeted may be smaller than we expect or our other assumptions with respect to the potential markets 
for our products and product candidates may not be correct and the markets may be significantly smaller than we 
expect.
There is no precise method of establishing in any geography over any period of time the actual number of patients 
with the diseases and disorders for which our products are indicated and our product candidates are targeted. With respect 
to any indications for which we have developed, are developing, or plan to develop products and product candidates, we 
estimate the prevalence of the disease or disorder, and our estimates as to prevalence, including the assumptions we apply 
in determining our estimate, may not be accurate. In each case, there is a range of estimates in the published literature and 
in marketing studies, which include estimates within the range that are lower than our estimates. For example, our 
estimates of the prevalence of PPD are higher than estimates reported in some of the published literature and results 
obtained from certain studies analyzing claims databases and include women who have symptoms of PPD but have not 
been formally diagnosed with PPD or may not meet all of the diagnostic criteria. We believe these differences may be the 
result of variations in analytical methodologies and possibly under-diagnosis of PPD as a result of inadequate screening 
and under-reporting and some patients being reluctant to seek treatment in clinical practice. The actual number of women 
with PPD or any other indication for which we are pursuing or may elect to pursue development of our product candidates 
may, however, be significantly lower than we believe. Even if our prevalence estimates are correct, any approved product 
that we develop may only be indicated for or prescribed to and used by a subset of patients with the relevant disease or 
disorder. Our assumptions and estimates about the potential markets for ZURZUVAE for the treatment of women with 
PPD and for our other current and future product candidates in the indications we are or may pursue may not be accurate. 
In the event the number of patients with the diseases and disorders we are studying is significantly lower than we expect, 
we or our collaborators may have difficulties in enrolling patients in our clinical trials which may delay or prevent 
development of our product candidates. If our prevalence estimates with respect to any indication or our other market 
assumptions are not accurate, the markets for any approved product for these indications may be smaller than we 
anticipate, which could limit our revenues and our ability to achieve profitability or to meet our expectations with respect 
to the level and timing of revenues or profits.
Positive results from non-clinical studies and clinical trials of our product candidates are not necessarily predictive of 
the results of later non-clinical studies and clinical trials of our product candidates in the same indications or other 
indications. Interim results from non-clinical studies and clinical trials may not be predictive of results of such non-
clinical studies or clinical trials once completed. If we cannot replicate the positive results from our earlier non-clinical 
studies and clinical trials of our product candidates in our later non-clinical studies and clinical trials in the same 
indications or other indications, or we cannot replicate our interim results in our completed non-clinical studies and 
clinical trials, we may be unable to successfully develop, obtain regulatory approval for and commercialize our product 
candidates.
Positive results from non-clinical studies and clinical trials of our product candidates may not necessarily be 
predictive of the results we or our collaborators may obtain from subsequent non-clinical studies or clinical trials using the 
same product candidate or other product candidates. Similarly, interim results from non-clinical studies and clinical trials 
may not be predictive of results of a non-clinical study or clinical trial once completed. For example, despite the results of 
prior clinical trials, our KINETIC 2, DIMENSION, LIGHTWAVE, and PRECEDENT Studies failed to meet their 
primary endpoints, as announced in 2024. As a result, we do not plan on continuing development of dalzanemdor, and 
Biogen terminated our collaboration agreement solely with respect to SAGE-324 on a worldwide basis, effective February 
17, 2025. We are evaluating next steps, if any, for other potential indications of SAGE-324, including seizures in DEEs, 
and we may choose not to further develop SAGE-324 in any indication.
We or our collaborators may also observe safety issues in clinical trials or non-clinical studies of our product 
candidates that we or they did not observe or appreciate in earlier stage clinical studies or non-clinical studies, or a 
different rate or severity of events, including as a result of an increase in dosing or in frequency or duration of dosing, 
studying a different patient population or different indication than previously studied, or administering a product 

53
candidate with a concomitant medication. For example, in the KINETIC 2 Study, for which we reported negative results 
in July 2024, we observed a dose-relationship in the incidence of CNS depressant TEAEs and in the frequency of TEAEs 
leading to study drug discontinuation in the study. Any of our studies may result in unexpected adverse events or raise 
other safety issues or may otherwise generate negative results. 
The results from non-clinical animal models may not be replicated in clinical trials, including, for example, in future 
clinical trials of SAGE-319 or any of our other product candidates. Many product candidates, including many targeting 
central nervous system disorders, with promising non-clinical profiles have failed to demonstrate similar safety, non-
toxicity and efficacy in humans.
Many companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in later-stage 
clinical trials after achieving positive results in earlier-stage development, and we cannot be certain that we will not face 
similar setbacks. Many drugs have failed to replicate efficacy and safety results in larger, longer or more complex later 
stage trials. Moreover, non-clinical and clinical data are often susceptible to varying interpretations and analyses, and 
many companies that believed their product candidates performed satisfactorily in non-clinical studies and clinical trials 
nonetheless failed to obtain FDA approval. If we or our collaborators fail to produce positive results in our ongoing and 
planned non-clinical studies or clinical trials of any of our product candidates, the development timeline and regulatory 
approval and commercialization prospects for our product candidates, and, correspondingly, our business and financial 
prospects, would be materially adversely affected.
Failures or delays by us or our collaborators in the commencement, enrollment or completion of our ongoing and 
planned clinical trials of our current and future product candidates could cause us not to meet our expected timelines 
or result in increased costs to us, and could delay, prevent or limit our ability to gain regulatory approval of any such 
product candidate and to generate revenue from resulting products, if any.
Successful completion of clinical trials at each applicable stage of development is a prerequisite to submitting an 
NDA to the FDA or equivalent filings outside the U.S. and, consequently, the ultimate approval and commercial 
marketing of any of our product candidates for the indications in which we develop them. We do not know whether we, or 
our collaborators, will complete and announce the results of any of our ongoing clinical trials, or whether future trials will 
begin, as planned or expected, if at all, as the commencement, enrollment, completion and announcement of results of 
clinical trials can be delayed or prevented for a number of reasons, including, among others:
•
denial by the FDA or other regulatory authority of permission to proceed with our planned clinical trials or any 
other clinical trials we may initiate, or placement of one or more clinical trials on full or partial clinical hold;
•
delay or inability to satisfy the requirements of the FDA to commence clinical trials, including chemistry, 
manufacturing and control, or CMC, requirements, or to file or receive approvals of additional investigational 
new drug applications, or INDs, that may be required;
•
delay or inability to satisfy the requirements for clinical trials conducted in the EU, if applicable, pursuant to 
Regulation (EU) No 536/2014, or the EU Clinical Trials Regulation;
•
negative or inconclusive results from our ongoing non-clinical studies or clinical trials;
•
challenges in identifying, recruiting, enrolling and retaining patients to participate in clinical trials;
•
challenges in qualifying and activating clinical trial sites, including due to capacity and resource constraints 
and attrition at sites, and potential delays at clinical trial sites;
•
general political and economic conditions, including as a result of future pandemics or other global health 
crises or bank failures;
•
delays in reaching or failing to reach agreement on acceptable terms with prospective contract research 
organizations, or CROs, and clinical trial sites, the terms of which can be subject to extensive negotiation and 
may vary significantly among different CROs and trial sites, or failures or problems by CROs or clinical trial 
sites in executing their activities under such agreements;
•
inadequate quantity or quality of supplies of a product candidate or other materials necessary to conduct 
clinical trials;

54
•
difficulties obtaining Institutional Review Board, or IRB, approval, and equivalent approval for sites outside 
the U.S., to conduct a clinical trial at a prospective site or sites;
•
delays or problems in analyzing data, or the need for additional analysis or data or the need to enroll additional 
patients;
•
the occurrence of serious adverse events or unexpected drug-related side effects experienced by patients in a 
clinical trial or unexpected results in ongoing non-clinical studies;
•
delays in validating endpoints utilized in a clinical trial or the impact of changes in trial design or analysis 
plans;
•
regulatory authorities disagreeing with our clinical trial design and our interpretation of data from clinical 
trials, or changing the requirements for approval even after the regulatory authority has reviewed and 
commented on the design for our clinical trials or delays caused by the need or desire for engagement with the 
applicable regulatory authorities; and
•
reports from non-clinical or clinical testing of other therapies that raise safety or efficacy concerns.
In addition, a clinical trial may be suspended or terminated by us, regulatory authorities, the IRB or ethics 
committee, or EC, at the sites where the IRBs or ECs are overseeing a clinical trial, or recommended for termination or 
suspension by a data and safety monitoring board overseeing the clinical trial at issue or other regulatory authorities due to 
a number of factors, including, among others:
•
failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols;
•
inspection of the clinical trial operations or trial sites by the FDA or other regulatory authorities that reveals 
deficiencies or violations that require us to undertake corrective action, including the imposition of a partial or 
full clinical hold;
•
unforeseen safety issues, including any that could be identified in our ongoing non-clinical studies, or adverse 
side effects or lack of effectiveness identified in ongoing clinical trials;
•
changes in government regulations or administrative actions; and
•
problems with clinical supply materials.
Additionally, changes in regulatory requirements, guidance or unanticipated events during our non-clinical studies 
and clinical trials or other reasons may cause us or our collaborators to amend non-clinical studies and clinical trial 
protocols or the applicable regulatory authorities may impose additional non-clinical studies and clinical trial 
requirements. Amendments or changes to clinical trial protocols would require resubmission to the FDA and IRBs for 
review and approval, which may adversely impact the cost, timing or successful completion of clinical trials. If we or our 
collaborators experience delays completing, or if we or our collaborators terminate, any of our non-clinical studies or 
clinical trials, or if we or our collaborators are required to conduct additional non-clinical studies or clinical trials, the 
development pathway, and ultimately the commercial prospects, for our product candidates may be harmed and our ability 
to generate product revenue from resulting products, if any, will be delayed.
Finally, if we or our collaborators are slow or unable to adapt to changes in existing requirements or the adoption of 
new requirements or policies governing clinical trials, our development plans may be impacted. For example, in 
December 2022, with the passage of Food and Drug Omnibus Reform Act, or FDORA, Congress required sponsors to 
develop and submit a diversity action plan for each Phase 3 clinical trial or any other “pivotal study” of a new drug or 
biological product. These plans are meant to encourage the enrollment of more diverse patient populations in late-stage 
clinical trials of FDA-regulated products. In June 2024, as mandated by FDORA, the FDA issued draft guidance outlining 
the general requirements for Diversity Action Plans, or DAPs. Unlike most guidance documents issued by the FDA, the 
DAP guidance when finalized will have the force of law because FDORA specifically dictates that the form and manner 
for submission of DAPs are specified in FDA guidance. On January 27, 2025, in response to an Executive Order issued by 
President Trump on January 21, 2025, on Diversity, Equity and Inclusion programs, the FDA removed this draft guidance 
from its website. This action raises questions about the applicability of statutory obligations to submit DAPs and the 
agency’s current thinking on best practices for clinical development. 

55
Similarly, the regulatory landscape related to clinical trials in the EU has evolved. The EU Clinical Trials 
Regulation, or CTR, which was adopted in April 2014 and repeals the EU Clinical Trials Directive, became applicable on 
January 31, 2022. While the EU Clinical Trials Directive required a separate clinical trial application to be submitted in 
each member state, to both the competent national health authority and an independent ethics committee, the CTR 
introduced a centralized process and only requires the submission of a single application to all member states concerned. 
If we or our collaborators are not able to fulfill these new requirements, our ability to conduct clinical trials may be 
delayed or halted.
We or our collaborators may never seek or receive regulatory approval to market any of our products or product 
candidates outside of the U.S. or receive pricing and reimbursement outside the U.S. at acceptable levels.
We or our collaborators may not seek, or may seek but never receive, regulatory approval to market our products or 
product candidates outside of the U.S. or in any particular country or region. In order to market any product outside of the 
U.S., we or our collaborators must establish and comply with the numerous and varying safety, efficacy and other 
regulatory requirements of other countries. Approval procedures vary among countries and can involve additional non-
clinical studies or clinical trials, additional work related to manufacturing and analytical testing on controls, and additional 
administrative review periods. The time required to obtain approvals in other countries might differ from that required to 
obtain FDA approval. Marketing approval in one country does not ensure marketing approval in another, but a failure or 
delay in obtaining marketing approval in one country may have a negative effect on the regulatory process in other 
countries. The marketing approval processes in other countries may implicate all of the risks detailed above regarding 
FDA approval in the U.S. as well as other risks. In particular, in many countries outside of the U.S., products must receive 
pricing and reimbursement approval before the product can be commercialized. Obtaining this approval may require 
additional studies and data, and can result in substantial delays in bringing products to market in such countries and such 
investment may not be justified from a business standpoint given the market opportunity or level of required investment. 
Even if we or our collaborators generate the data and information which we or our collaborators believe may be sufficient 
to file an application for regulatory approval of any of our products or product candidates in a region or country outside 
the U.S., the relevant regulatory agency may find that we or our collaborators did not meet the requirements for approval, 
or even if our application is approved, we may have significant post-approval obligations. 
We or our collaborators could face heightened risks with respect to seeking marketing approval in the United 
Kingdom, or UK, as a result of the withdrawal of the UK from the EU, commonly referred to as Brexit. The UK is no 
longer part of the European Single Market and EU Customs Union. As of January 1, 2021, the MHRA became 
responsible for supervising medicines and medical devices in Great Britain, comprising England, Scotland and Wales 
under domestic law, whereas Northern Ireland will continue to be subject to EU rules under the Northern Ireland Protocol. 
The MHRA will rely on the Human Medicines Regulations 2012 (SI 2012/1916) (as amended), known as the HMR, as the 
basis for regulating medicines. The HMR has incorporated into the domestic law of the body of EU law instruments 
governing medicinal products that pre-existed prior to the UK’s withdrawal from the EU. Any delay in obtaining, or an 
inability to obtain, any marketing approvals, as a result of Brexit or otherwise, may force us or our collaborators to restrict 
or delay efforts to seek regulatory approval in the UK for our or their product candidates, which could significantly and 
materially harm our business.
Even if we or our collaborators are able to successfully develop our product candidates and obtain marketing 
approval in a country outside the U.S., we or they may not be able to obtain pricing and reimbursement approvals in such 
country at acceptable levels or at all, and any pricing and reimbursement approval we or they may obtain may be subject 
to onerous restrictions such as caps, rebates or other hurdles or restrictions on reimbursement. Failure to obtain marketing 
and pricing approval in countries outside the U.S. without onerous restrictions or limitations related to pricing, or any 
delay or other setback in obtaining such approval, would impair our ability or that of our collaborators to market our 
product candidates successfully or at all in such foreign markets. Any such impairment would reduce the size of our 
potential market or revenue potential, which could have a material adverse impact on our business, results of operations 
and prospects.
Any setback or delay in obtaining regulatory approval or commencing marketing, if approved, for our product 
candidates in a country or region outside the U.S. where we or our collaborators have decided it makes business sense to 
proceed may have a material adverse effect on our business and prospects.

We rely completely on third-party suppliers to manufacture commercial supplies of our products and clinical drug 
supplies for our product candidates, and we intend to rely on third parties to produce non-clinical, clinical and 
commercial supplies of our products and product candidates in the future. 
We do not currently have, nor do we plan to acquire or develop, the infrastructure or capability internally to 
manufacture supplies of our products, including ZURZUVAE, for commercial use or any of our other existing or future 
product candidates, for use in the conduct of our clinical trials and non-clinical studies or for future commercial use, and 
we rely completely on third-party suppliers for both active drug substances and finished drug products. 
We rely on our contract manufacturers to manufacture sufficient quantities of ZURZUVAE active drug substance, 
finished drug product and packaged and labeled product. We also previously relied on our contract manufacturers for 
commercial supplies of active drug substance, finished drug product and packaged and labeled product with respect to 
ZULRESSO until we discontinued ZULRESSO commercial availability in the U.S. as of December 31, 2024. We also 
rely on our contract manufacturers to manufacture sufficient quantities of our product candidates for ongoing and planned 
clinical trials and non-clinical studies and expect to rely on them to scale our manufacturing processes for future clinical 
trials, if our development efforts are successful. 
We expect our contract manufacturers to comply with current Good Manufacturing Practices, or cGMPs, in the 
manufacture of our products. The facilities used by our contract manufacturers to manufacture the active pharmaceutical 
ingredient and final drug product may be required to complete a pre-approval inspection by the FDA and other 
comparable foreign regulatory authorities to assess compliance with applicable requirements, including cGMPs, after we 
submit the relevant NDA or equivalent foreign regulatory submission to the applicable regulatory agency. Contract 
manufacturers are subject to inspections by the FDA and regulatory authorities outside the U.S. If the FDA or other 
regulatory authorities were to identify deficiencies in connection with the inspections of our contract manufacturers for 
our products or any of our product candidates, the FDA could issue a Form 483, and other regulatory authorities could 
issue equivalent documents, documenting these deficiencies and require that we provide and comply with a corrective 
action plan, which could impact our ability to supply product or any of our product candidates. If our contract 
manufacturers cannot successfully manufacture material that conforms to our specifications and the strict regulatory 
requirements of the FDA or other foreign regulatory authorities, and pass regulatory inspections, on the timelines we 
expect or at all, they will not be able to secure and/or maintain regulatory approval for their manufacturing facilities with 
respect to our products. 
We have no direct control over our contract manufacturers’ ability to maintain adequate quality control, quality 
assurance and qualified personnel. All of our third-party contract manufacturers are engaged with other companies to 
supply and/or manufacture materials or products for such companies, which exposes our third-party contract 
manufacturers to regulatory risks for the production of such materials and products. As a result, failure to satisfy the 
regulatory requirements for the production of those materials and products may affect the regulatory clearance of our 
contract manufacturers’ facilities generally. If the FDA or an applicable foreign regulatory agency determines now or in 
the future that these facilities for the manufacture of our products and product candidates are noncompliant, we may need 
to find alternative manufacturing facilities, which would significantly and adversely delay or impact our 
commercialization efforts for any approved product and our ability to develop and obtain regulatory approval for our 
product candidates. Our reliance on contract manufacturers also exposes us to the possibility that they, or third parties 
with access to their facilities, will have access to and may appropriate our trade secrets or other proprietary information. 
Also, if a natural disaster, or other events, were to interrupt or halt production of our drug substance or drug product at one 
of our third-party contract manufacturers, or cause the loss of batches, we could encounter a supply shortage or face 
significant costs to rebuild our supply.
We have a long-term supply agreement with our contract manufacturer for ZURZUVAE drug product. We have an 
inventory of ZURZUVAE drug product and drug substance in place to help mitigate any potential supply risks, but there 
is no guarantee that this inventory will be adequate. We do not have arrangements in place for either long-term supply or 
redundant supply of drug substance or drug product for our product candidates. Each batch of drug substance and drug 
product for our product candidates is individually contracted through a purchase order governed by master service and 
quality agreements.
If our existing contract manufacturing organizations, or CMOs, for our product candidates are unwilling to enter into 
long-term supply agreements, or are unwilling or unable to supply drug substance or drug product to us, we could be 

57
required to engage new CMOs who would need to scale up the manufacturing process before we would be able to use the 
drug product or drug substance they manufacture for clinical trials or for future commercialization, if we are successful 
and gain approval. In addition, any CMO will need to complete validation batches and be approved by regulatory 
authorities (including passing any required inspections) as our manufacturer before we would be able to use drug product 
or drug substance they manufacture for commercial purposes, which could result in significant delays or gaps in product 
availability. We plan to continue to rely upon CMOs to manufacture commercial quantities of ZURZUVAE and of any 
future products that may be approved. If we are unable to maintain arrangements for third-party manufacturing or are 
unable to do so on commercially reasonable terms, or are unable to obtain timely regulatory approvals in connection with 
our CMOs, we may not be able to successfully commercialize any approved product, including ZURZUVAE, or 
successfully complete development of our current or future product candidates.
Any of our current or future products or product candidates, including ZURZUVAE, may not achieve and maintain 
broad market acceptance or reimbursement at sufficient levels, which would limit the revenue that we generate from 
sales.
The commercial success of ZURZUVAE in the U.S. for the treatment of women with PPD, or of any of our current 
or future products or product candidates, if successfully developed and approved by the FDA or other applicable 
regulatory authorities, will depend upon the awareness and acceptance among healthcare professionals, patients, policy-
makers and healthcare payors, and reimbursement at sufficient levels. 
The availability of coverage and adequacy of reimbursement is essential for most patients to be able to access and 
afford treatments. Patients who are prescribed medications for the treatment of their conditions generally rely on third-
party payors to reimburse all or part of the costs associated with their prescription drugs. Government authorities, 
including the Centers for Medicare & Medicaid Services, or CMS, an agency within the Department of Health and Human 
Services, or HHS, in the U.S., and third-party payors, such as private health insurers and health maintenance 
organizations, or HMOs, decide which medications they will pay for and establish reimbursement levels for those 
medications. Cost containment is a primary concern in the U.S. healthcare industry and elsewhere. Government 
authorities and these third-party payors have attempted to control costs by limiting coverage and the amount of 
reimbursement for particular medications. Payors may adopt restrictions on coverage for any of our products, including 
ZURZUVAE, such as requiring patients to try other lower cost therapies prior to reimbursing our product, requiring 
patients to meet certain severity levels on measurement scales or other criteria more restrictive than the approved label for 
our products, or requiring other onerous and time-consuming forms of utilization management, such as prior authorization 
procedures. They may limit the amount of reimbursement or restrict access altogether. These restrictions or limitations 
might impede appropriate use of our products for any approved indications. For example, some payors currently require 
that healthcare professionals attest that the women with PPD for whom they have prescribed ZURZUVAE have severe 
symptoms. Restrictions and limitations on reimbursement or delays in obtaining coverage may vary significantly among 
payors and payor types. As a result, there is uncertainty related to maintaining third-party payor coverage and 
reimbursement of ZURZUVAE or any of our product candidates, if successfully developed and approved. Coverage and 
reimbursement by a third-party payor may depend upon a number of factors, including the third-party payor’s 
determination that use of a product is a covered benefit under its health plan; safe, effective and medically necessary; 
appropriate for the specific patient; cost-effective; and neither experimental nor investigational. Regulatory approvals, 
pricing and reimbursement for drug products vary widely from country to country.
The inability of us or our collaborators to promptly obtain and maintain coverage and adequate reimbursement rates 
from both government-funded and private payors for ZURZUVAE for the treatment of women with PPD, and any other 
approved products that we develop could have a material adverse effect on our operating results, our ability to 
successfully commercialize our products, our ability to raise capital and our overall financial condition. Even if coverage 
is provided, we may not be able to realize a sufficient return on our investment, including as a result of restrictions on the 
type of coverage that is achieved or because we are unable to establish or maintain sufficient pricing.
Obtaining and maintaining coverage and reimbursement approval for a product from a government or other third-
party payor can be an expensive and time-consuming process that could require us to provide supporting scientific, 
clinical and cost effectiveness data for the use of our products to the payor. The industry competition to be included in 
third-party payors’ drug formularies, or lists of medications for which third-party payors provide coverage and 
reimbursement, often leads to downward pricing pressures on pharmaceutical products. In addition, third-party payors 

58
may refuse to include a particular branded drug in their formularies or otherwise restrict patient access to a branded drug 
when a less costly generic equivalent or other alternative is available. Net prices for drugs may be reduced by mandatory 
discounts or rebates required by government healthcare programs or private payors, and by any future relaxation of laws 
that presently restrict imports of drugs from countries where they may be sold at lower prices than in the U.S. 
Increasingly, third-party payors are requiring that drug companies provide them with predetermined discounts from list 
prices and are challenging the prices charged for medical products. In addition, many pharmaceutical manufacturers must 
calculate and report certain price reporting metrics to the government, such as average sales price and best price. Penalties 
may apply when such metrics are not submitted accurately and on a timely basis. Before granting reimbursement 
approval, payors may require us to demonstrate, directly or indirectly, that our product candidates, in addition to treating 
the target indications, also provide incremental health benefits to patients or healthcare costs savings. We cannot be sure 
that adequate coverage or reimbursement will be available for any of our products and product candidates on reasonable 
terms or at all.
Market acceptance for any of our approved products and any product candidates that we successfully develop will 
depend on a number of factors, including, among others:
•
the efficacy and safety of our products as demonstrated in clinical trials or in real world use;
•
the potential and perceived advantages and limitations of our products over current or future alternative 
treatment options, including in the case of ZURZUVAE for the treatment of women with PPD, the availability 
of lower cost antidepressants;
•
the incidence and severity of any side effects of the products;
•
limitations or warnings contained in the labeling approved for our products by the FDA or other applicable 
regulatory authorities, such as the boxed warning for ZURZUVAE related to driving impairment and other 
warnings, precautions and risks identified in the label;
•
the clinical indications and size of patient populations for which our products are approved;
•
the convenience, risk-benefit profile, ease and availability of alternative treatments already approved or 
expected to be commercially launched in the near future;
•
the willingness of the target patient population to try new therapies and of healthcare professionals to prescribe 
these therapies, and our ability to increase awareness of our approved products through marketing efforts;
•
the strength and effectiveness of our sales, marketing and distribution strategies and support or that of our 
collaborators;
•
publicity concerning our products or competing products and treatments;
•
pricing and cost effectiveness; or
•
the availability of sufficient third-party coverage or reimbursement, the nature and complexity of restrictions 
on coverage, and the willingness of patients to pay out-of-pocket in the absence of such coverage or 
reimbursement.
Our and our collaborators’ efforts to change the treatment paradigm for a given disorder or to educate the medical 
community and third-party payors about the benefits of any current or future products, to the extent permitted, including 
ZURZUVAE for the treatment of women with PPD, may require significant resources and may never be successful. If any 
of our current or future products, including ZURZUVAE, does not achieve an adequate level of acceptance by patients, 
healthcare professionals, and payors, or reimbursement at reasonable levels and without significant or complex 
restrictions, or if the patient population for which any such product is approved is smaller than we expect, we may not 
generate sufficient revenue from our products to become or remain profitable or to adequately fund operations or may not 
do so to the degree or on the timelines we expect. 

59
Even if marketing approval is granted for a product, we may face significant post-marketing obligations and future 
development and regulatory difficulties. 
Regulatory authorities may impose significant and potentially costly post-marketing obligations with respect to 
approval of any product, including post-marketing studies, additional CMC work and additional pediatric studies. For 
example, the FDA has imposed post-marketing commitments with respect to approval of ZULRESSO and ZURZUVAE, 
and we may encounter issues or delays in the conduct of these post-marketing commitments or we may generate 
unexpected results. For ZURZUVAE, the FDA is requiring two post-marketing studies: a pharmacokinetic and safety 
study in adolescent females who have completed puberty and an embryofetal toxicity study in a second species.
In the event we or our collaborators elect, or are required, to proceed with pediatric studies of any of our product 
candidates in any indication, regulatory authorities may also require additional non-clinical studies or clinical trials be 
completed prior to commencement of such pediatric studies. 
As was the case with zuranolone and brexanolone, the FDA may recommend controlled substance scheduling for 
our current or future product candidates. If products are determined to be controlled substances, the manufacturing, 
shipping, storing, selling and using of the products will be subject to an additional regulation. Distribution, prescribing 
and dispensing of these drugs are also regulated. Because of their restrictive nature, these laws and regulations could limit 
commercialization of our product candidates containing controlled substances. Failure to comply with these laws and 
regulations could also result in withdrawal of our DEA registrations, disruption in manufacturing and distribution 
activities, consent decrees, criminal and civil penalties and state actions, among other consequences. The DEA regulates 
controlled substances as Schedule I, II, III, IV or V substances. Schedule I substances by definition have no established 
medicinal use, and may not be marketed or sold in the U.S. A pharmaceutical product may be listed as Schedule II, III, IV 
or V, with Schedule II substances considered to present the highest risk of abuse and Schedule V substances the lowest 
relative risk of abuse among such substances. ZURZUVAE (zuranolone) and ZULRESSO (brexanolone) are currently 
regulated as a Schedule IV controlled substances. Other Schedule IV controlled substances include sedative hypnotics 
such as benzodiazepines.
ZURZUVAE is, and any future approved products will also be, subject to ongoing FDA requirements governing the 
labeling, packaging, storage and promotion of the product and record-keeping and submission of safety and other post-
market information. The FDA has significant post-marketing authority, including, for example, the authority to require 
labeling changes based on new safety information and to require post-marketing studies or clinical trials to evaluate 
serious safety risks, safety and efficacy in pediatric populations or alternate doses or dose regimens. 
The FDA also has the authority to require, as part of an NDA or post-approval, the submission of a REMS. For 
example, the FDA required a REMS for ZULRESSO. Any REMS required by the FDA may lead to increased costs to 
assure compliance with the REMS and with additional post-approval regulatory requirements and potential requirements 
or restrictions on the sale of approved products, all of which could lead to lower sales volume and revenue. In addition, if 
we are unable to comply with any REMS imposed on any of our products, we may face additional restrictions, limitations 
or substantial penalties, any of which may materially adversely affect our business and results of operations.
We, our collaborators and the third-party manufacturers of our drug substance and drug products and our respective 
facilities are subject to extensive regulations in the manufacture of our products and product candidates, including GMP, 
and are subject to continual review and periodic inspections by the FDA and other regulatory authorities for compliance 
with GMPs and other regulations. If we, our collaborators or a regulatory agency discover problems with our approved 
products or product candidates such as poor control of production processes or other problems with the facility where our 
products are manufactured or in the manufacturing process, introduction of contaminants, or adverse events of 
unanticipated severity or frequency, a regulatory agency may impose restrictions on our products, the manufacturer or us 
or our collaborators, including requiring withdrawal of such products from the market or suspension of manufacturing. If 
we, our collaborators, our approved products, our product candidates, or the manufacturers for our products or product 
candidates fail to comply with applicable regulatory requirements, a regulatory agency may, among other things:
•
issue warning letters or untitled letters;
•
seek an injunction or impose civil or criminal penalties or monetary fines;
•
suspend or withdraw marketing approval;

60
•
suspend any ongoing clinical trials;
•
refuse to approve pending applications or supplements to applications submitted by us;
•
suspend or impose restrictions on operations, including costly new manufacturing requirements; or
•
seize or detain products, refuse to permit the import or export of products, or require that we initiate a product 
recall.
In addition, we could be adversely affected by several significant administrative law cases decided by the U.S. 
Supreme Court in 2024. In Loper Bright Enterprises v. Raimondo, for example, the U.S. Supreme Court overruled 
Chevron U.S.A., Inc. v. Natural Resources Defense Council, Inc., which for 40 years required federal courts to defer to 
permissible agency interpretations of statutes that are silent or ambiguous on a particular topic. The U.S. Supreme Court 
stripped federal agencies of this presumptive deference and held that courts must exercise their independent judgment 
when deciding whether an agency such as the FDA acted within its statutory authority under the Administrative Procedure 
Act, or the APA. Additionally, in Corner Post, Inc. v. Board of Governors of the Federal Reserve System, the U.S. 
Supreme Court held that actions to challenge a federal regulation under the APA can be initiated within six years of the 
date of injury to the plaintiff, rather than the date the rule is finalized. The decision appears to give prospective plaintiffs a 
personal statute of limitations to challenge longstanding agency regulations. Another decision, Securities and Exchange 
Commission v. Jarkesy, overturned regulatory agencies’ ability to impose civil penalties in administrative proceedings. 
These decisions introduce additional uncertainty into the regulatory process and may result in additional legal challenges 
to actions taken by federal regulatory agencies, including the FDA and CMS, that we rely on. In addition to potential 
changes to regulations as a result of legal challenges, these decisions may result in increased regulatory uncertainty and 
delays and other impacts, any of which could adversely impact our business and operations. 
Further, our ability to develop and market new drug products may be impacted by litigation challenging the FDA’s 
approval of another company’s drug product. In April 2023, the U.S. District Court for the Northern District of Texas 
invalidated the approval by the FDA of mifepristone, a drug product which was originally approved in 2000 and whose 
distribution is governed by various measures adopted under a REMS. The U.S. Court of Appeals for the Fifth Circuit 
declined to order the removal of mifepristone from the market but did hold that plaintiffs were likely to prevail in their 
claim that changes allowing for expanded access of mifepristone, which the FDA authorized in 2016 and 2021 were 
arbitrary and capricious. In June 2024, the U.S. Supreme Court reversed that decision after unanimously finding that the 
plaintiffs (anti-abortion doctors and organizations) did not have standing to bring this legal action against the FDA. On 
October 11, 2024, the attorneys general of three states (Missouri, Idaho and Kansas) filed an amended complaint in the 
district court in Texas challenging the FDA’s actions. Depending on the outcome of this litigation, our ability to develop 
new drug product candidates and to maintain approval of existing drug products could be delayed, undermined or subject 
to protracted litigation. 
Finally, with the change in presidential administrations in 2025, there is substantial uncertainty as to how, if at all, 
the new administration will seek to modify or revise the requirements and policies of the FDA and other regulatory 
agencies with jurisdiction over our product candidates. The impending uncertainty could present new challenges or 
potential opportunities as we navigate the clinical development and approval process for our product candidates.
Competing therapies may exist or could be approved that adversely affect the amount of revenue we are able to 
generate from the sale of ZURZUVAE or any of our other current or future product candidates, if successfully 
developed and approved.
The biopharmaceuticals industry is highly competitive. There are many public and private companies, universities, 
governmental agencies and other research organizations actively engaged in the research and development of products 
that may be similar to our products or product candidates or address similar markets. It is probable that the number of 
companies seeking to develop products and therapies similar to our products or targeting similar indications will increase. 
Many of our potential competitors, alone or with their strategic partners, have substantially greater financial, technical and 
human resources than we do, and significantly greater experience in the discovery and development of product candidates, 
obtaining FDA and other regulatory approvals of treatments and the commercialization of those treatments. Mergers and 
acquisitions in the biotechnology and pharmaceutical industries may result in even more resources being concentrated 
among a smaller number of our competitors. We expect competition in the indications we are pursuing will focus on 
efficacy, safety, convenience, availability, and price. Our commercial opportunity could be reduced or eliminated if our 

61
competitors develop and commercialize products that are perceived to be safer, more effective, have fewer or less severe 
side effects, are more convenient or are less expensive than any 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, which could result in our competitors establishing a strong market position before we are able to 
enter the market.
Currently, the only pharmacological therapies specifically approved for the treatment of PPD are ZURZUVAE and 
ZULRESSO. We discontinued commercial availability of ZULRESSO in the U.S. as of December 31, 2024. 
ZURZUVAE currently competes with the current standard of care for PPD, which commonly consists of psychotherapy; 
however, patients with moderate or severe symptoms of PPD are often prescribed antidepressant medications such as 
selective serotonin reuptake inhibitors, or SSRIs, and serotonin and norepinephrine reuptake inhibitors, or SNRIs. 
ZURZUVAE may also face competition from drugs currently in development, if successfully developed and approved in 
the future for the treatment of PPD, including potentially LPCN 1154, an oral formulation of the neuroactive steroid 
brexanolone under development by Lipocine, Inc. under the streamlined 505(b)(2) regulatory pathway, which allows for 
potential approval of an abbreviated NDA by the FDA, and BRII-296, an intramuscular formulation of brexanolone being 
developed by Brii Biosciences.  
In the field of neuroactive steroids focused specifically on modulation of GABAA receptors, we also face 
competition from a number of companies, including Marinus Pharmaceuticals, Inc. (acquired by Immedica Pharma AB), 
which received FDA approval of ganaxolone, a known GABAA positive allosteric modulator neuroactive steroid, to treat 
seizures associated with CDKL5 deficiency disorder, a rare, genetic epilepsy. Other GABAA competitors include 
darigabat, which is being developed by Cerevel Therapeutics, Inc. (acquired by AbbVie Inc.) for the treatment of epilepsy 
and panic disorder.
Our existing collaborations with Biogen and Shionogi, and any future collaborations, may not lead to the successful 
development or regulatory approval of product candidates or commercialization of products. Our collaborators may 
have competing priorities, conflicting incentives, or different views than us on key decisions, including regulatory, 
development or commercialization strategy or appropriate program spending, that may hamper or delay our 
development and commercialization efforts or increase our costs. Our business may be adversely affected and we may 
be subject to delays, disputes, or litigation if we and any of our collaborators disagree significantly, if any of our 
collaborators fails to perform its obligations or terminates our collaboration, or if we are not able to establish future 
collaborations that we believe to be important to our business on commercially reasonable terms. 
Our drug development programs, the commercialization of ZURZUVAE for the treatment of women with PPD, and 
any potential commercialization of our product candidates will require substantial additional cash to fund expenses. For 
some of our product candidates, we may decide to collaborate with pharmaceutical and biotechnology companies for the 
development and potential commercialization of those product candidates in some or all markets.
We and our collaboration partner Biogen achieved regulatory approval in the U.S. of ZURZUVAE for the treatment 
of adults with PPD, and launched ZURZUVAE for that indication. Our collaboration with Biogen may not lead to 
successful commercialization of ZURZUVAE in the U.S. or successful development of zuranolone in Biogen’s ex-U.S. 
territory. In the third quarter of 2023, our collaboration partner, Shionogi, filed an NDA in Japan for zuranolone for the 
treatment of MDD; however, Shionogi may not be successful in obtaining regulatory approval for zuranolone for the 
treatment of MDD, or if approved, may not be successful in commercializing zuranolone in Japan. Our existing and future 
collaborations, if any, may also not lead to the successful development and commercialization of ZURZUVAE in other 
indications or territories or of any other products. Our collaborators face both the same challenges and hurdles that we 
would face in the development and commercialization of product candidates if we were engaged in the activities solely 
ourselves, as well as additional challenges related to operating under a collaboration. The efforts under our existing 
collaborations may not be successful and we may never meet applicable milestones or actually receive any additional 
milestone payments, profit-share revenue or royalty payments from Biogen or Shionogi. For example, while ZURZUVAE 
was approved for the treatment of adults with PPD in the U.S., the FDA issued a CRL to the NDA for zuranolone for the 
treatment of MDD in the U.S. Because we and Biogen have agreed not to pursue further development for zuranolone for 
the treatment of MDD in the U.S., we will not receive the $150.0 million milestone payment for the first commercial sale 
of ZURZUVAE for the treatment of MDD in the U.S. Our collaborators may decide to terminate their collaboration with 
us. For example, in September 2024, after we and Biogen decided to discontinue development of SAGE-324 in essential 

62
tremor, Biogen notified us of its termination of our collaboration agreement solely with respect to SAGE-324 on a 
worldwide basis, effective February 17, 2025. We are evaluating next steps, if any, for other potential indications of 
SAGE-324, including seizures in DEEs. We may choose not to further develop SAGE-324 in this or any other indication. 
Additional risks and uncertainties relating to our collaboration with Biogen are set forth in the Risk Factor above 
captioned “Our plans to explore strategic alternatives and our rejection of an unsolicited, non-binding acquisition 
proposal from Biogen to acquire all of our outstanding shares not owned by Biogen may have a material adverse effect on 
our business.” 
In addition, under most collaborations, including our existing collaborations, a certain degree of control in decision-
making is transferred to or shared with our collaborators. Our collaborators may use their decision-making authority to 
make decisions that could delay, decrease the potential of, or otherwise adversely impact, development of our product 
candidates or commercialization of approved products. Similarly, where we share decision-making authority, the need to 
gain alignment on decisions may slow or impede advancement of or appropriate investment in our programs or 
commercialization of an approved product, and cause us not to be able to meet our timelines or achieve our goals. Our 
collaborators may have competing priorities or different incentives that cause them to divert resources away from our 
collaboration, or we may not agree on appropriate spending levels or regulatory, development or commercialization 
strategy, which could hamper or delay our overall development and commercialization efforts or increase our overall 
spending. Our collaborators may independently develop, or develop with a competitor, competitive products or may 
believe that product candidates being evaluated in the collaboration could be competitive with the collaborator’s own 
products. In the case of the collaboration with Biogen, both companies have agreed to certain exclusivity provisions for 
certain products in specified indications which may limit certain development opportunities outside the collaboration. In 
addition, if we depend on collaborators for capabilities and funding for major product development efforts or 
commercialization globally or in key territories then our business may be adversely affected if our collaborator fails to 
perform its obligations under the agreement or the collaboration terminates. Disputes may also arise with respect to the 
ownership of rights to technology or products developed with collaborators, which could have an adverse effect on our 
ability to develop and commercialize any affected product candidate.
Collaborations are complex and time-consuming to negotiate and document. In addition, there have been a 
significant number of recent business combinations among large pharmaceutical companies that have resulted in a 
reduced number of potential future collaborators. We may not be able to negotiate additional collaborations on a timely 
basis, on acceptable terms, or at all.
We may not be successful in our efforts to identify or discover additional product candidates beyond our existing 
product candidates or to file IND applications for clinical development of new compounds at the rate we expect, or we 
may expend our limited resources to pursue a particular product candidate or indication and fail to capitalize on 
product candidates or indications that may be more profitable or for which there is a greater likelihood of success.
The success of our business depends upon our and our collaborators’ ability not only to successfully commercialize 
existing approved products but also to develop, gain approval of and commercialize products based on our current product 
candidates and to generate new compounds for development in the future and to successfully complete the non-clinical 
work necessary to file INDs to pursue clinical development of such new compounds. Our research programs may fail to 
generate new compounds that meet the standards for non-clinical development. Even if we are successful in generating 
such compounds, we may not be able to produce the non-clinical and other data necessary to support IND applications for 
clinical development, in each case in the number or at the rate we expect or at all for a number of reasons. For example, 
we may not be able to identify a sufficient number of new targets in areas of interest to us. Our research methodology may 
be unsuccessful in generating a sufficient number of new compounds appropriate for non-clinical testing in the target 
areas we identify. Even if we generate new compounds in areas of interest to us, we may determine that those compounds 
are not appropriate for non-clinical development, or we may generate data in non-clinical development that do not support 
IND filings for clinical development. We may not have, or devote, sufficient technical, financial, and human resources to 
our research efforts at the various stages needed to identify targets, generate compounds, conduct non-clinical studies and 
prepare INDs. Additional potential product candidates may be shown to have harmful side effects or may not have a 
positive risk/benefit profile or may have other characteristics that may make the product candidates not appropriate for 
further development or unlikely to receive marketing approval. Further, even if we generate new compounds in areas of 
interest, we may determine that those compounds are not worth pursuing for strategic reasons, including new legislation 
that may impact the viability of commercializing such compounds, if approved.

Because we have limited financial and management resources, we focus on a limited number of clinical and research 
programs and product candidates and are currently focused on certain brain health disorders. As a result, we may forego 
or delay pursuit of opportunities with certain product candidates or for other indications that later prove to have greater 
commercial potential. Research programs to identify new product candidates require substantial technical, financial and 
human resources. We may focus our efforts and resources on potential programs or product candidates that ultimately 
prove to be unsuccessful and may not yield any commercially viable drugs. For example, we recently discontinued 
development of dalzanemdor and are considering whether to continue development of SAGE-324 in other indications, 
after our clinical trials for both programs failed to meet their primary endpoints. Our resource allocation decisions may 
cause us to fail to capitalize on other viable opportunities. If we do not accurately evaluate the commercial potential or 
target market for a particular product candidate, we may relinquish valuable rights through future collaborations, licensing 
or other royalty arrangements in cases in which it would have been more advantageous for us to retain such sole 
development and commercialization rights. If any of these events occur, it may have a material adverse effect on our 
business.
We rely, and expect that we will continue to rely, on third parties to conduct any clinical trials for our product 
candidates. If these third parties do not successfully carry out their contractual duties, comply with applicable 
standards and meet expected deadlines, we may not be able to successfully develop and obtain regulatory approval for 
our product candidates, and our business could be substantially harmed.
We do not have the ability to independently conduct clinical trials. We rely on medical institutions, clinical 
investigators, contract laboratories and other third parties, such as CROs, to conduct clinical trials of our product 
candidates. We enter into agreements with third-party CROs to provide monitors for and to manage data for our ongoing 
clinical trials. We rely heavily on these parties for execution of clinical trials for our product candidates and control only 
certain aspects of their activities. As a result, we have less direct control over the conduct, timing and completion of these 
clinical trials and the management of data developed through clinical trials than would be the case if we were relying 
entirely upon our own staff. Communicating with outside parties can also be challenging, potentially leading to mistakes 
as well as difficulties in coordinating activities. Outside parties may:
•
have staffing difficulties and shortages, attrition of experienced staff, and other resource constraints;
•
fail to comply with contractual obligations;
•
fail to comply with current Good Clinical Practices, or GCPs, or experience other regulatory compliance 
issues;
•
undergo changes in priorities or become financially distressed; 
•
misappropriate our intellectual property;
•
form relationships with other entities, some of which may be our competitors; or
•
be impacted by changes to the macroeconomic and geopolitical environment or disruptions arising from 
pandemics or other global heath crises, and the downstream effects of these changes or disruptions.
These factors may materially adversely affect the willingness or ability of third parties to conduct our clinical trials, 
and may subject us to unexpected cost increases that are beyond our control. In addition, certain Chinese CROs that 
supply us with medicinal chemistry and drug metabolism research may become subject to trade restrictions, sanctions, and 
other regulatory requirements by the U.S. government, including the proposed BIOSECURE Act, any of which could 
restrict or even prohibit our ability to work with such entities, thereby potentially disrupting our research activities. Such 
disruption could have adverse effects on the development of our product candidates and our business operations.
Nevertheless, we and our collaborators are responsible for ensuring that each of our clinical trials is conducted in 
accordance with the applicable protocol, legal and regulatory requirements, and scientific standards, and our reliance on 
CROs does not relieve us of our regulatory responsibilities. We and our collaborators, clinical investigators, and our 
CROs are required to comply with regulations and guidelines, including GCPs, for conducting, monitoring, recording and 
reporting the results of clinical trials to ensure that the data and results are scientifically credible and accurate, and that the 
trial patients are adequately informed of the potential risks of participating in clinical trials. These regulations are enforced 
by the FDA, the Competent Authorities of the Member States of the European Economic Area, or EEA, and comparable 
foreign regulatory authorities for any product candidates in clinical development or where clinical trials are being 

64
conducted. If we or our CROs or CMOs fail to comply with these regulations or if the quality or accuracy of the clinical 
data obtained is compromised due to the failure to adhere to our clinical protocols or other regulatory requirements or for 
other reasons, and we and our collaborators are unable to rely on clinical data collected, we and our collaborators may be 
required to repeat clinical trials or extend the duration of, or increase the size of, our clinical trials, or we may not be able 
to rely on the results of our clinical trials. This would delay the regulatory approval process, and could also subject us to 
enforcement action up to and including civil and criminal penalties. If any of our relationships with third-party CROs 
terminate or if a CRO needs to be replaced, we may not be able to enter into arrangements with alternative CROs in a 
timely manner or at all. Any of these issues could significantly delay or prevent regulatory approval of our product 
candidates and require significantly greater expenditures. In such an event, we believe that our financial results might be 
harmed, our costs could increase and our ability to generate revenue from products beyond ZURZUVAE could be 
delayed.
Our future success depends on our ability to attract, retain and motivate qualified personnel.
To accomplish our objectives, we require a strong management team with expertise in research and development, 
clinical development and commercialization. Although we have entered into employment agreements with each of our 
executive officers, each of them is employed “at will” and may terminate his or her employment with us at any time. We 
do not maintain “key person” insurance for any of our executives or other employees. Recruiting and retaining qualified 
personnel is critical to our success. We may not be able to attract and retain these personnel on acceptable terms given the 
competition among numerous pharmaceutical and biotechnology companies for similar personnel. We also experience 
competition for the hiring of scientific personnel from universities and research institutions. Failure to succeed in 
commercializing approved products or in conducting clinical trials or in obtaining regulatory approval may make it more 
challenging to recruit and retain qualified personnel. If we are unable to continue to attract and retain high quality 
personnel, our development efforts, commercialization activities, business, financial condition, results of operations and 
growth prospects could be adversely affected.
We face potential product liability exposure, and, if claims are brought against us, we may incur substantial liability.
The sale of ZURZUVAE and any future approved products, and the use of our product candidates in clinical trials 
expose us to the risk of product liability claims. In addition, product liability claims related to ZULRESSO may arise 
and/or be brought even though we discontinued commercial availability of the product as of December 31, 2024. Product 
liability claims might be brought against us by patients, healthcare professionals or others using, prescribing, selling or 
otherwise coming into contact with our products and product candidates. For example, we may be sued if any product or 
product candidate allegedly causes injury or is found to be otherwise unsuitable during clinical trials, manufacturing, 
marketing, sale or commercial use. Any such product liability claims may include allegations of defects in manufacturing, 
defects in design, a failure to warn of dangers inherent in the product, including as a result of interactions with alcohol or 
other drugs, knowledge of risks, negligence, strict liability and a breach of warranties. Claims could also be asserted under 
state consumer protection laws. If we become subject to product liability claims and cannot successfully defend ourselves 
against them, we could incur substantial liabilities. Regardless of merit or eventual outcome, product liability claims may 
result in, among other things:
•
withdrawal of patients from our clinical trials, or difficulty in enrolling clinical trials;
•
substantial monetary awards to patients or other claimants;
•
decreased demand for our approved products;
•
damage to our reputation and exposure to adverse publicity;
•
increased FDA warnings on product labels;
•
litigation costs;
•
distraction of management’s attention from our primary business;
•
loss of revenue; and
•
withdrawal of products from the market or our inability to successfully gain approval of product candidates.

65
Although we maintain product liability insurance coverage, our insurance coverage may be insufficient to reimburse 
us for any expenses or losses we may suffer. Moreover, 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, including if insurance coverage becomes 
increasingly expensive. Large judgments have been awarded in class action lawsuits based on drugs that had unanticipated 
side effects. The cost of any product liability litigation or other proceedings, even if resolved in our favor, could be 
substantial, particularly in light of the size of our business and financial resources. A product liability claim or series of 
claims brought against us could cause our stock price to decline and, if we are unsuccessful in defending such a claim or 
claims and the resulting judgments or settlements exceed our insurance coverage, our financial condition, business and 
prospects could be materially adversely affected.
If we fail to comply with our reporting and payment obligations under the Medicaid Drug Rebate Program or other 
governmental pricing programs, we could be subject to additional reimbursement requirements, penalties, sanctions 
and fines, which could have a material adverse effect on our business, financial condition, results of operations and 
growth prospects.
The Medicaid Drug Rebate Program, which we participate in, and other governmental programs impose obligations 
to report pricing figures to the federal government, require us to pay rebates and participate in discount programs. Other 
programs impose limits on the price we or our collaborators are permitted to charge certain entities for ZURZUVAE or 
for any future products for which we receive regulatory approval. Statutory and regulatory changes or binding guidance 
regarding these programs and their requirements could negatively affect the coverage and reimbursement by these 
programs of ZURZUVAE or any future products for which we receive regulatory approval and could negatively impact 
our results of operations. Our failure to comply with these price reporting and rebate payment obligations could negatively 
impact our financial results. The Patient Protection and Affordable Care Act, as amended, referred to herein as the ACA, 
and regulations promulgated thereunder could affect our obligations in ways we cannot anticipate. 
Pricing and rebate calculations vary among products and programs. The calculations are complex and are often 
subject to interpretation by us, governmental or regulatory authorities and the courts. If we become obligated to restate or 
recalculate the amounts we report under these programs, our costs for complying with the laws and regulations governing 
the Medicaid Drug Rebate Program and our price discounts and rebates could be increased. Additionally, we could be 
held liable for errors associated with our submission of pricing data under the Medicaid Drug Rebate Program and other 
federal or state drug pricing programs, including retroactive rebates and program refunds, and if we are found to have 
knowingly submitted false average manufacturer price or best price information to the government, we could be subject to 
civil monetary penalties per item of false information. Certain failures to submit required data could result in a civil 
monetary penalty for each day the information is late beyond the due date and be grounds for CMS to terminate our 
Medicaid drug rebate agreement, pursuant to which we participate in the Medicaid program, or, if we fail to comply with 
340B program requirements, the Health Resources and Services Administration, or HRSA, could decide to terminate our 
340B program participation agreement. In the event that CMS terminates our rebate agreement or HRSA terminates our 
340B program participation agreement, no federal payments would be available under Medicaid or Medicare Part B for 
our covered outpatient drugs. We are also subject to civil monetary and other penalties applicable to the drug pricing 
negotiation program and Part B and Part D inflation rebate programs, as discussed further below under the risk factor 
entitled “Healthcare regulations aimed at reducing healthcare costs may have a material adverse effect on our business 
or results of operation.” 
We are subject to other laws and regulations, which could expose us to investigation, criminal sanctions, civil 
penalties, administrative penalties, contractual damages, reputational harm and diminished profits and future 
earnings.
We are subject to a number of healthcare and other statutory and regulatory requirements and enforcement by the 
federal government and the states and foreign governments in the countries in which we currently or may in the future 
conduct our business. 
Our current or future interactions and arrangements with third-party payors, healthcare professionals, patients, 
healthcare settings, and others who play a role in the recommendation, prescription, reimbursement and administration of 
ZURZUVAE, and will play a similar role with respect to any of our current or future product candidates, if successfully 
developed and approved, are governed in part by broadly applicable fraud and abuse and other healthcare laws and 
regulations that may constrain the business or financial arrangements and relationships through which we market, sell and 

66
distribute ZURZUVAE, or expect to market, sell and distribute any future approved products. Restrictions under 
applicable federal and state healthcare laws and regulations include the following:
•
The federal Anti-Kickback Statute prohibits, among other things, persons from knowingly and willfully 
soliciting, offering, receiving or providing remuneration, directly or indirectly (including any kickback, bribe 
or certain rebates), in cash or in kind, to induce or reward either the referral of an individual for, or the 
purchase, order or recommendation of, any good or service, for which payment may be made under federal 
healthcare programs such as Medicare and Medicaid. This statute has been interpreted to apply to 
arrangements between pharmaceutical companies on the one hand, and prescribers, purchasers and formulary 
managers, among others, on the other. 
•
The federal False Claims Act imposes criminal and civil penalties, including those from civil whistleblower or 
qui tam actions, against individuals or entities for knowingly presenting, or causing to be presented, to the 
federal government, claims for payment that are false or fraudulent or making a false statement to avoid, 
decrease, or conceal an obligation to pay money to the federal government, with potential liability including 
mandatory treble damages and significant per-claim penalties. Pharmaceutical companies have faced 
enforcement actions under the False Claims Act in connection with their alleged off-label promotion of drugs, 
purportedly concealing price concessions in the pricing information submitted to the government for 
government price reporting purposes, and allegedly providing free product to customers with the expectation 
that the customers would bill federal healthcare programs for the product, among other activities. In addition, 
the government may assert that a claim, including items or services resulting from a violation of the federal 
Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the False Claims Act.
•
The federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, imposes criminal and 
civil liability for executing a scheme to defraud any healthcare benefit program and also imposes privacy, 
security and breach reporting obligations, including mandatory contractual terms, with respect to safeguarding 
the privacy, security and transmission of individually identifiable health information upon covered entities 
subject to the rule.
•
The federal false statements statute prohibits knowingly and willfully falsifying, concealing or covering up a 
material fact or making any materially false statement in connection with the delivery of or payment for 
healthcare benefits, items or services.
•
The federal transparency requirements, sometimes referred to as the “Sunshine Act”, under the ACA require 
manufacturers of drugs, devices, biologics and medical supplies that are reimbursable under Medicare, 
Medicaid, or the Children’s Health Insurance Program to report to CMS information related to physician 
payments and other transfers of value made to physicians, certain non-physician providers, and teaching 
hospitals, as well as ownership and investment interests held by physicians and their immediate family 
members.
•
Analogous state laws and regulations, such as state anti-kickback and false claims laws and transparency laws, 
may apply to sales or marketing arrangements and claims involving healthcare items or services reimbursed by 
non-governmental third-party payors, including private insurers, and some state laws require pharmaceutical 
companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant 
compliance guidance promulgated by the federal government in addition to requiring drug manufacturers to 
report information related to payments to physicians and other healthcare professionals or marketing 
expenditures and drug pricing.
•
Various federal and state health information and data protection laws and regulations, and similar types of laws 
outside the U.S., govern the collection, use, disclosure and protection of health-related and other personal 
information by us and our collaborators.
Ensuring that our future practices and business arrangements comply with applicable healthcare laws and regulations 
is costly. It is possible that governmental authorities will conclude that our business practices and arrangements do not 
comply with current or future statutes, regulations or case law involving applicable fraud and abuse or other healthcare 
laws and regulations. If our practices or operations, including activities conducted by our commercial team or other of our 
employees, consultants or vendors, were found to be in violation of any of these laws or any other governmental 

67
regulations that may apply to us, we may be subject to significant civil, criminal and administrative penalties, damages, 
fines and exclusion from government-funded healthcare programs, such as Medicare and Medicaid, any of which could 
substantially disrupt our operations and materially adversely affect our business and financial condition. We may also be 
substantially negatively impacted if governmental authorities conclude that the business practices of one of our 
collaborators does not comply with applicable laws or regulations. If any of the physicians or other providers or entities 
with whom we expect to do business are found not to be in compliance with applicable laws or regulations, they may be 
subject to criminal, civil or administrative sanctions, including exclusions from government-funded healthcare programs.
We and our employees are also subject to other statutes and regulations related to our business, including: 
regulations imposed by the FDA and applicable non-U.S. regulators, as previously discussed; anti-bribery and anti-
corruption laws and regulations applicable to activities outside the U.S.; rules on reporting financial and other information 
or data timely and accurately; and rules related to insider trading.
Moreover, principal investigators for our clinical trials may serve as scientific advisors or consultants to us and 
receive compensation in connection with such services. Under certain circumstances, we may be required to report some 
of these relationships to regulatory authorities. Regulatory authorities may conclude that a financial relationship between 
us and a principal investigator has created a conflict of interest or otherwise affected the interpretation of the study. 
Regulatory authorities may therefore question the integrity of the data generated at the applicable clinical trial site and the 
utility of the clinical trial itself may be jeopardized. This could result in a delay in approval, or rejection, of our marketing 
applications by regulatory authorities, as the case may be, and may ultimately lead to the denial of marketing approval of 
one or more of our product candidates.
Although we have adopted a code of conduct and have an active compliance program, it is not always possible to 
identify and deter employee, consultant, vendor or collaborator misconduct, and the precautions we take to detect and 
prevent this activity may be ineffective in controlling unknown or unmanaged risks or losses or in protecting us from 
governmental investigations or other actions or lawsuits stemming from a failure by such persons to comply with these 
laws or regulations. 
Data collection is governed by restrictive regulations governing the use, processing, and cross-border transfer of 
personal information. Compliance with these regulations can be time-consuming and onerous. If we are found to have 
improperly handled personal information, we may become subject to fines and penalties, litigation and reputational 
harm.
We must comply with numerous federal, state and non-U.S. laws which govern the privacy and security of health 
and other personal information. As described above, to the extent applicable to our business activities, HIPAA imposes 
certain requirements relating to the privacy, security and transmission of individually identifiable health information. In 
addition, when we conduct clinical trials in the U.S., any personal information that is collected in connection with these 
trials also is regulated by the Federal Policy for the Protection of Human Subjects (the Common Rule) which creates 
obligations for our company when conducting these trials.
We may enroll subjects in our future clinical trials in the EU or other countries. When we do so, we may be subject 
to additional privacy restrictions, including restrictions relating to the collection, use, storage, transfer, and other 
processing of personal data, including personal health data, regarding these individuals. Clinical trial activities in the 
EEA, for example, are governed by the General Data Protection Regulation, or GDPR, in relation to the processing of 
personal data. The GDPR imposes several requirements on companies that process personal data, strict rules on the 
transfer of personal data out of the EEA, including to the U.S., and fines and penalties for failure to comply with the 
requirements of the GDPR and the related national data protection laws of the EU Member States. The GDPR also confers 
a private right of action on data subjects and consumer associations to lodge complaints with supervisory authorities, seek 
judicial remedies, and obtain compensation for damages resulting from violations of the GDPR in some situations. The 
obligations under the GDPR may be onerous and adversely affect our business, financial condition, results of operations 
and prospects. Compliance with the GDPR is a rigorous and time-intensive process that may increase our cost of doing 
business or require us to change our business practices, and despite those efforts, there is a risk that we may be subject to 
fines and penalties, litigation, and reputational harm in connection with any European activities, including processing of 
personal data originating from the EU. The issues related to the transfer of personal data are subject to substantial 
uncertainty at this time, and there can be no reasonable level of confidence that any such data transfers will be found to be 
consistent with EU law if they are challenged. The exit of the UK from the EU, often referred to as Brexit, has created 

68
uncertainty with regard to future data protection regulation in the UK. The European Commission has adopted an 
adequacy decision concerning the level of data protection in the UK. Personal data may now flow freely from the EEA to 
the UK; however, the European Commission may suspend the adequacy decision if it decides that the UK no longer 
provides for an adequate level of data protection. Similar laws exist in many other countries around the world, and these 
laws (which are evolving and expanding) create complicated and potentially inconsistent obligations that may impact our 
business.
We are also subject to the California Consumer Privacy Act, as amended by the California Privacy Rights Act, or the 
CCPA, which creates individual privacy rights for California consumers (as defined in the law) and places increased 
privacy and security obligations on entities handling personal data of consumers or households. While there is currently 
an exception for protected health information that is subject to HIPAA and clinical trial regulations, as currently written, 
the CCPA may impact our business activities. Failure to comply with the CCPA may result in, among other things, 
significant civil penalties and injunctive relief, or statutory or actual damages. In addition, California consumers have the 
right to bring a private right of action in connection with certain types of incidents. These claims may result in significant 
liability and damages. 
In addition to California, several other states have passed comprehensive privacy laws similar to the CCPA. These 
laws are either in effect or will go into effect sometime before the end of 2026. Like the CCPA, these laws create 
obligations related to the processing of personal information, as well as special obligations for the processing of 
“sensitive” data, which includes health data in some cases. Some of the provisions of these laws may apply to our 
business activities. Other states will be considering similar laws in the future. There are also states that are specifically 
regulating health information that may affect our business. For example, Washington state passed a health privacy law 
that will regulate the collection and sharing of health information, and the law also has a private right of action. 
Connecticut and Nevada have also passed similar health-specific consumer privacy laws. These laws and regulations are 
constantly evolving and may impose limitations on our business activities.
Plaintiffs’ lawyers are also increasingly using privacy-related statutes at both the state and federal level to bring 
lawsuits against companies for their data-related practices. In particular, there have been a significant number of cases 
filed against companies for their use of pixels and other web trackers. These cases often allege violations of the California 
Invasion of Privacy Act and other state laws regulating wiretapping, as well as the federal Video Privacy Protection Act. 
The rise in these types of lawsuits creates potential risk for our business.
In addition, there are substantial efforts at the federal level to pass a national data privacy law that may impact our 
business activities. The uncertainty, ambiguity, complexity and potential inconsistency surrounding the implementation 
and interpretation of laws at the state and federal levels exemplify the vulnerability of our business to the evolving 
regulatory environment related to the privacy, security and confidentiality of personal data and consumer health 
information. We may be subject to fines, penalties, or private actions in the event of non-compliance with such laws. 
These laws may impact our business activities, including our identification of research subjects, relationships with 
business partners and ultimately the marketing and distribution of our products. We have implemented processes to 
manage compliance with applicable laws and continue to assess their impact on our business as additional information and 
guidance becomes available.
In addition to the foregoing, any breach of privacy laws or data security laws, particularly resulting in a significant 
security incident or breach involving the misappropriation, loss or other unauthorized use or disclosure of sensitive or 
confidential patient or consumer information, could have a material adverse effect on our business, reputation and 
financial condition. As a data controller, we will be accountable for any third-party service providers we engage to 
process personal data on our behalf, including our CROs. There is no assurance that privacy and security-related 
safeguards we implement will protect us from all risks associated with the third-party processing, storage and transmission 
of such information. In certain situations, both in the U.S. and in other countries, we also may be obligated as a result of a 
security breach to notify individuals and/or government entities about these breaches.

69
The FDA and other regulatory and enforcement agencies actively enforce the laws and regulations prohibiting the 
promotion of off-label uses. If we are found to have improperly promoted off-label uses, we may become subject to 
significant liability.
The FDA and other regulatory and enforcement authorities strictly regulate the promotional claims that may be 
made about prescription products, and enforce laws and regulations prohibiting the promotion of unapproved, or “off-
label” uses. In particular, a product may not be promoted for uses that are not approved by the FDA or such other 
regulatory authorities as reflected in the approved labeling of the product. For example, ZURZUVAE is approved in the 
U.S. for the treatment of adults with PPD only and may not be promoted for any uses that are not approved by the FDA, 
including MDD. If we are found to have promoted off-label uses for any product, we may become subject to significant 
liability. The federal government has levied large civil and criminal fines against companies for alleged improper 
promotion and has taken steps to restrict promotional activities of those companies. Pharmaceutical companies have also 
been prosecuted and incurred significant civil, criminal and administrative penalties, damages, and fines under the False 
Claims Act in connection with their alleged off-label promotion of drugs. Any promotion of the off-label use of 
ZURZUVAE or any of our other products by us or any of our employees could subject us to significant liability, which 
would materially adversely affect our business and financial condition.
We will need to carefully navigate the FDA’s various regulations, guidance and policies, along with recently enacted 
legislation, to ensure compliance with restrictions governing promotion of our products. In September 2021, the FDA 
published final regulations which describe the types of evidence that the Agency will consider in determining the intended 
use of a drug or biologic. Moreover, with passage of the Pre-Approval Information Exchange Act in December 2022, 
sponsors of products that have not been approved may proactively communicate to payors certain information about 
products in development to help expedite patient access upon product approval. In addition, in January 2025, the FDA 
published final guidance outlining its policies governing the distribution of scientific information to healthcare providers 
about unapproved uses of approved products. The final guidance calls for such communications to be truthful, non-
misleading and scientifically sound and to include all information necessary for healthcare providers to interpret the 
strengths and weaknesses and validity and utility of the information about the unapproved use of the approved product. If 
a company engages in such communications consistent with the guidance’s recommendations, the FDA indicated that it 
will not treat such communications as evidence of unlawful promotion of a new intended use for the approved product. 
While this guidance only applies to communications about unapproved uses of approved products, it may be helpful in 
understanding the FDA’s approach to communications about unapproved products.
Our future growth may depend, in part, on our ability to penetrate foreign markets, where we would be subject to 
additional regulatory burdens, price controls, reimbursement issues and other risks and uncertainties, and could 
negatively impact our U.S. business.
Our future profitability may depend, in part, on our ability, ourselves or through our collaborators, to commercialize 
our products and product candidates in foreign markets. 
The pricing of prescription pharmaceuticals in foreign markets is subject to foreign governmental control. In these 
countries, pricing negotiations with governmental authorities can take considerable time after the receipt of regulatory 
approval for a product. To obtain reimbursement or pricing approval in some countries, we may be required to conduct a 
clinical trial that compares the cost-effectiveness of our product candidates to other available therapies. If reimbursement 
of our products is unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, our or our 
collaborators’ ability to generate revenues and become profitable could be impaired. In addition, these factors could 
impact our or our collaborators’ decision on whether to commercialize a product candidate, even if successfully developed 
and approved. 
In some countries, including Member States of the EU, the pricing of prescription drugs is subject to governmental 
control. Additional countries may adopt similar approaches to the pricing of prescription drugs. There can be considerable 
pressure by governments and other stakeholders on prices and reimbursement levels, including as part of cost containment 
measures. Political, economic and regulatory developments may further complicate pricing negotiations, and pricing 
negotiations may continue after coverage and reimbursement have been obtained. Reference pricing used by various 
countries and parallel distribution, or arbitrage between low-priced and high-priced countries, can further reduce prices. In 
the U.S., recent legislative and administrative policies and proposals signal a desire to lower drug prices in the U.S. As a 
result, we or our collaborators outside the U.S. in the future may be limited in the prices we are able to charge for our 

70
products in the U.S. Publication of discounts by third-party payors or authorities may lead to further pressure on the prices 
or reimbursement levels within the country of publication and other countries. If pricing is set at unsatisfactory levels or if 
reimbursement of our products is unavailable or limited in scope or amount, our revenues from sales by us or our 
collaborators and the potential profitability of our products in those countries would be negatively affected.
Commercializing our products and product candidates in foreign markets would subject us to additional risks and 
uncertainties, including:
•
our inability to directly control commercial activities to the extent we are relying on third parties;
•
the burden of complying with complex and changing foreign regulatory, tax, accounting and legal 
requirements, including the interpretation of contractual provisions governed by foreign laws in the event of a 
contract dispute;
•
different medical practices and customs in foreign countries affecting acceptance in the marketplace;
•
import or export licensing requirements;
•
longer accounts receivable collection times;
•
reduced protection of intellectual property rights, and the existence of additional potentially relevant third-
party intellectual property rights, in some foreign countries; and
•
foreign currency exchange rate fluctuations.
Foreign sales of our product candidates could also be adversely affected by the imposition of governmental controls, 
political and economic instability, trade restrictions and changes in tariffs. For example, Brexit has already and may 
continue to adversely affect European and/or worldwide regulatory conditions. Brexit could continue to lead to legal 
uncertainty and potentially divergent national laws and regulations in the EU and the UK, including those related to the 
pricing of prescription pharmaceuticals, as the UK determines which EU laws to replicate or replace, which could impair 
our ability to transact business in the EU and the UK in the future, if we elect to seek to commercialize any of our

Risks Related to Our Intellectual Property Rights
If we are unable to adequately protect our proprietary technology, or obtain and maintain issued patents that are 
sufficient to protect our product candidates, others could compete against us more directly, which would have a 
material adverse impact on our business, results of operations, financial condition and prospects.
We strive to protect and enhance the proprietary technologies that we believe are important to our business, 
including seeking patents intended to cover our products and compositions, their methods of use and any other inventions 
that are important to the development of our business. We may 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.
Our success will depend significantly on our ability to obtain and maintain patent and other proprietary protection 
for commercially important technology, inventions and know-how related to our business; defend and enforce our patents, 
should they issue; preserve the confidentiality of our trade secrets; and operate without infringing the valid and 
enforceable patents and proprietary rights of third parties. We also rely on know-how, continuing technological innovation 
and in-licensing opportunities to develop, strengthen and maintain the proprietary position of our product candidates. 
We cannot provide any assurances that any of our pending patent applications will mature into issued patents. For 
example, the U.S. Patent and Trademark Office, or U.S. PTO, has issued a final rejection against one of our patent 
applications claiming one of our proprietary GABAA positive allosteric modulator compounds, asserting a lack of novelty 
and non-obviousness. We are in the process of appealing the rejection, and may not be successful in overturning the 
rejection. 
We may be unable to obtain issued patents covering our proprietary compounds. We cannot provide any assurances 
that any of our issued patents will be enforceable, or include claims with a scope sufficient to protect our product 

71
candidates or otherwise provide any competitive advantage. For example, the issued patent and patent applications that 
provide coverage for ZULRESSO only cover particular formulations and particular methods of using such formulations to 
treat depressive disorders such as PPD and MDD. As a result, such issued patent and any patent that may issue from such 
patent applications, would not prevent third-party competitors from creating, making and marketing alternative 
formulations of brexanolone that fall outside the scope of the patent claims or from practicing alternative methods. 
Moreover, other parties have developed technologies that may be related or competitive to our approach, and may have 
filed or may file patent applications and may have received or may receive patents that may overlap or conflict with our 
patent applications, either by claiming the same methods or formulations or by claiming subject matter that could 
dominate our patent position. Such third-party patent positions may limit or even eliminate our ability to obtain patent 
protection for certain inventions.
The patent positions of biotechnology and pharmaceutical companies, including our patent position, involve 
complex legal and factual questions, and, therefore, the issuance, scope, validity and enforceability of any patent claims 
that we may obtain cannot be predicted with certainty. Patents, if issued, may be challenged, deemed unenforceable, 
invalidated, or circumvented. U.S. patents and patent applications may also be subject to interference proceedings, 
derivation proceedings, ex parte reexamination, or inter partes review proceedings, post-grant review proceedings, 
supplemental examination and challenges in district court. Patents may be subjected to opposition, post-grant review, or 
comparable proceedings lodged in various foreign, both national and regional, patent offices. These proceedings could 
result in either loss of the patent or denial of the patent application or loss or reduction in the scope of one or more of the 
claims of the patent or patent application. In addition, such proceedings may be costly. For example, certain of our granted 
patents have, in the past, been opposed by third parties, and further such proceedings in the future could result in 
revocation or amendment of our patents in such a way that they no longer cover our product candidates or competitive 
products. Thus, any patents, should they issue, that we may own or exclusively license may not provide any protection 
against competitors. Furthermore, an adverse decision in an interference proceeding or a derivation proceeding can result 
in a third party receiving the patent right sought by us, which in turn could affect our ability to develop, market or 
otherwise commercialize our product candidates. Furthermore, though a patent, if it were to issue, is presumed valid and 
enforceable, its issuance is not conclusive as to its validity or its enforceability, and it may not provide us with adequate 
proprietary protection or competitive advantages against competitors with similar products. Even if a patent issues, and is 
held to be valid and enforceable, competitors may be able to design around our patents, such as using pre-existing or 
newly developed technology. Other parties may develop and obtain patent protection for more effective technologies, 
designs or methods.
We also may not be able to prevent the unauthorized disclosure or use of our technical knowledge or trade secrets by 
consultants, vendors, former employees and current employees. The laws of some foreign countries do not protect our 
proprietary rights to the same extent as the laws of the U.S., and we may encounter significant problems in protecting our 
proprietary rights in these countries. If these developments were to occur, they could have a material adverse effect on our 
sales if any of our product candidates are approved in those countries. Our ability to enforce our patent rights depends on 
our ability to detect infringement. It is difficult to detect infringers who do not advertise the components that are used in 
their products. Moreover, it may be difficult or impossible to obtain evidence of infringement in a competitor’s or 
potential competitor’s product. Any litigation to enforce or defend our patent rights, even if we were to prevail, could be 
costly and time-consuming, and would divert the attention of our management and key personnel from our business 
operations. We may not prevail in any lawsuits that we initiate, and the damages or other remedies awarded if we were to 
prevail may not be commercially meaningful.
In addition, proceedings to enforce or defend our patents, if and when issued, could put our patents at risk of being 
invalidated, held unenforceable, or interpreted narrowly. Such proceedings could also provoke third parties to assert 
claims against us, including that some or all of the claims in one or more of our patents are invalid or otherwise 
unenforceable. If any of our patents, if and when issued, covering our product or product candidates is invalidated or 
found unenforceable, our financial position and results of operations may be materially and adversely impacted. In 
addition, if a court found that valid, enforceable patents held by third parties covered our product candidates, our financial 
position and results of operations may also be materially and adversely impacted.

72
The degree of future protection for our proprietary rights is uncertain, and we cannot ensure that:
•
any of our pending patent applications, if issued as a patent, will include claims having a scope sufficient to 
protect our current product candidates or any other products or product candidates;
•
any of our pending patent applications will issue as patents at all;
•
we will be able to generate significant revenue from sales of ZURZUVAE or any of our product candidates, if 
successfully developed and approved, before our relevant patents expire;
•
we were the first to make the inventions covered by each of our pending patent applications and any patents 
that may issue in the future;
•
we were the first to file patent applications for these inventions;
•
others will not develop similar or alternative technologies that do not infringe any patents that have been or 
may be issued to us;
•
others will not use pre-existing technology to effectively compete against us;
•
any of our patents, if issued or as issued, will provide us with a competitive advantage and be found ultimately 
to be valid and enforceable;
•
any patents issued to us will provide a basis for an exclusive market for our commercially viable products, will 
provide us with any competitive advantages or will not be challenged by third parties;
•
we will develop additional proprietary technologies or product candidates that are separately patentable; or
•
that our commercial activities or products will not infringe upon the patents or proprietary rights of others.
We may rely upon unpatented trade secrets and depend on unpatented know-how and continuing technological 
innovation to develop and maintain our competitive position, which we seek to protect, in part, by confidentiality 
agreements with our employees and our CROs, collaborators and consultants. It is possible that technology relevant to our 
business will be independently developed by a person that is not a party to such an agreement. Furthermore, if the 
employees and consultants who are parties to these agreements breach or violate the terms of these agreements, we may 
not have adequate remedies for any such breach or violation, and we could lose our trade secrets through such breaches or 
violations. Further, our trade secrets could otherwise become known or be independently discovered by our competitors.
We may infringe the intellectual property rights of others, which may prevent or delay our product development efforts 
and stop us from commercializing or increase the costs of commercializing ZURZUVAE or any of our product 
candidates that we may successfully develop.
Our success will depend in part on our ability to operate without infringing the intellectual property and proprietary 
rights of third parties. We cannot assure you that our business, products and methods do not or will not infringe the 
patents or other intellectual property rights of third parties. The pharmaceutical industry is characterized by extensive 
litigation regarding patents and other intellectual property rights. Other parties may allege that our products or product 
candidates or the use of our technologies infringes patent claims or other intellectual property rights held by them or that 
we are employing their proprietary technology without authorization. As we continue to develop our current product 
candidates and commercialize ZURZUVAE and any future products, competitors may claim that our technology infringes 
their intellectual property rights as part of business strategies designed to impede our successful commercialization. There 
may be third-party patents or patent applications with claims to materials, formulations, methods of manufacture or 
methods for treatment related to the use or manufacture of our product candidates. Because patent applications can take 
many years to issue, third parties may have currently pending patent applications which may later result in issued patents 
that our products or product candidates may infringe, or which such third parties claim are infringed by our technologies. 
The outcome of intellectual property litigation is subject to uncertainties that cannot be adequately quantified in advance. 
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 product candidates, 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. Even if we are successful in these proceedings, we may incur substantial costs and the time and 
attention of our management and scientific personnel could be diverted in pursuing these proceedings, which could have a 

73
material adverse effect on us. In addition, we may not have sufficient resources to bring these actions to a successful 
conclusion.
Patent and other types of intellectual property litigation can involve complex factual and legal questions, and their 
outcome is uncertain. Patent litigation is costly and time-consuming. Any claim relating to intellectual property 
infringement that is successfully asserted against us may require us to pay substantial damages, including treble damages 
and attorney’s fees if we are found to be willfully infringing another party’s patents, for past use of the asserted 
intellectual property and royalties and other consideration going forward if we are forced to take a license. In addition, if 
any such claim were successfully asserted against us and we could not obtain such a license, we may be forced to stop or 
delay developing, manufacturing, selling or otherwise commercializing our product or product candidates. In the case of 
trademark claims, if we are found to be infringing, we may be required to redesign, or rename, some or all of our product 
candidates to avoid infringing the intellectual property rights of third parties, which may not be possible and, even if 
possible, could be costly and time-consuming. Even if we are successful in these proceedings, we may incur substantial 
costs and divert management time and attention in pursuing these proceedings, which could have a material adverse effect 
on us.
Any of these risks coming to fruition could have a material adverse effect on our business, results of operations, 
financial condition and prospects.
We may be subject to claims challenging the inventorship or ownership of our patents and other intellectual property.
We enter into confidentiality and intellectual property assignment agreements with our employees, consultants, 
CROs, outside scientific collaborators, and other advisors. These agreements generally provide that inventions conceived 
by the party in the course of rendering services to us will be our exclusive property. However, these agreements may not 
be honored and/or may not effectively assign intellectual property rights to us. For example, even if we have a consulting 
agreement in place with an academic advisor pursuant to which such academic advisor is required to assign to us any 
inventions developed in connection with providing services to us, such academic advisor may not have the right to assign 
such inventions to us, as it may conflict with his or her obligations to assign all such intellectual property to his or her 
employing institution or another party.
Most of our employees have also been previously employed at other biotechnology or pharmaceutical companies, 
including our competitors or potential competitors. We also engage advisors and consultants who are concurrently 
employed at universities or who perform services for other entities. We may be subject to claims that an employee, 
advisor or consultant performed work for us that conflicts with that person’s obligations to a third party, such as an 
employer, and thus, that the third party has an ownership interest in the intellectual property arising out of work performed 
for us.
Litigation may be necessary to defend against these and other claims challenging inventorship or ownership. If we 
fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property 
rights, such as exclusive ownership of, or right to use, valuable intellectual property. Such an outcome could have a 
material adverse effect on our business. Even if we are successful in defending against such claims, litigation could result 
in substantial costs and be a distraction to management and other employees, which could have a material adverse effect 
on our business.
Obtaining and maintaining our patent protection depends on compliance with various procedural, document 
submission, fee payment and other requirements imposed by governmental patent agencies, and our patent protection 
could be reduced or eliminated for noncompliance with these requirements.
The U.S. PTO and various foreign governmental patent agencies require compliance with a number of procedural, 
documentary, fee payment and other formalities and provisions during the patent process. There are situations in which 
noncompliance can result in abandonment or lapse of a patent or patent application, resulting in partial or complete loss of 
patent rights in the relevant jurisdiction. In such an event, competitors might be able to enter the market earlier than would 
otherwise have been the case.

74
We may be involved in lawsuits to protect or enforce our patents or the patents of our licensors, which could be 
expensive, time-consuming, and unsuccessful.
Even if the patent applications we own or license are issued, competitors may infringe these patents. To counter 
infringement or unauthorized use, we may be required to file infringement claims, which can be expensive and time-
consuming. In addition, in an infringement proceeding, a court may decide that a patent of ours or our licensors is not 
valid, is unenforceable and/or is not infringed, or may refuse to stop the other party from using the technology at issue on 
the grounds that our patents should be interpreted narrowly and do not cover the technology in question. An adverse result 
in any litigation or defense proceedings could put one or more of our patents at risk of being invalidated or interpreted 
narrowly and could put our patent applications at risk of not issuing.
Interference proceedings or derivation proceedings provoked by third parties or brought by us may be necessary to 
determine the priority of inventions with respect to our patents or patent applications or those of our 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. Our defense of litigation or interference proceedings may fail and, even if successful, may result in 
substantial costs and distract our management and other employees. We may not be able to prevent, alone or with our 
licensors, misappropriation of our intellectual property rights, particularly in countries where the laws may not protect 
those rights as fully as in the U.S.
Furthermore, 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. There could also 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 material adverse 
effect on the price of our common stock.
Issued patents covering our products or any of our product candidates could be found invalid or unenforceable if 
challenged in court.
If we or one of our collaborators or licensors initiated legal proceedings against a third party to enforce a patent, if 
and when issued, covering our products or any of our product candidates, the defendant could counterclaim that the patent 
covering our products or any of our product candidates is invalid and/or unenforceable. In patent litigation in the U.S., 
defendant counterclaims alleging invalidity and/or unenforceability are commonplace. Grounds for a validity challenge 
include alleged failures to meet any of several statutory and non-statutory requirements, including lack of novelty, 
obviousness, non-statutory obviousness type double patenting, lack of written description, or non-enablement. Grounds 
for unenforceability assertions include allegations that someone connected with prosecution of the patent withheld 
relevant information from the U.S. PTO, or made a misleading statement, during prosecution. Third parties may also raise 
similar claims before administrative bodies in the U.S. or abroad, even outside the context of litigation. Such mechanisms 
include re-examination, post-grant review, ex parte reexamination, inter partes review, derivation proceedings or 
interferences and equivalent proceedings in foreign jurisdictions, e.g., opposition or revocation proceedings. Such 
proceedings could result in revocation or amendment of our patents in such a way that they no longer cover our product 
candidates or competitive products. Certain of our granted patents have, in the past, been opposed by third parties, and 
further such proceedings in the future could result in revocation or amendment of our patents in such a way that they no 
longer cover our product candidates or competitive products. The outcome following legal assertions of invalidity and 
unenforceability is unpredictable. With respect to validity, for example, we cannot be certain that there is no invalidating 
prior art of which we and the patent examiner were unaware during prosecution. If a defendant were to prevail on a legal 
assertion of invalidity and/or unenforceability, we would lose at least part, and perhaps all, of the patent protection on the 
applicable product or product candidates. Such a loss of patent protection could have a material adverse impact on our 
business.
We will not seek to protect our intellectual property rights in all jurisdictions throughout the world, and we may not be 
able to adequately enforce our intellectual property rights even in the jurisdictions where we seek protection.
Filing patent applications and prosecuting and defending patents on products and product candidates in all countries 
and jurisdictions throughout the world would be prohibitively expensive, and our intellectual property rights in some 
countries outside the U.S. could be less extensive than those in the U.S., assuming that rights are obtained in the U.S. In 

75
addition, the laws of some foreign countries do not protect intellectual property rights to the same extent as federal and 
state laws in the U.S. Consequently, we may not be able to prevent third parties from practicing our inventions in all 
countries outside the U.S., or from selling or importing products made using our inventions in and into the U.S. or other 
jurisdictions. The statutory deadlines for pursuing patent protection in individual foreign jurisdictions are based on the 
priority date of each of our patent applications.
Competitors may use our technologies in jurisdictions where we do not pursue patent protection. They may pursue 
and obtain their own patent protection to develop their own products. Further, they may export otherwise infringing 
products to territories where we have patent protection, but enforcement is not as strong as that in the U.S. These products 
may compete with our products and our patents or other intellectual property rights may not be effective or sufficient to 
prevent them from competing. Even if we pursue and obtain issued patents in particular jurisdictions, our patent claims or 
other intellectual property rights may not be effective or sufficient to prevent third parties from so competing.
The laws of some foreign countries do not protect intellectual property rights to the same extent as the laws of the 
U.S. Many companies have encountered significant problems in protecting and defending intellectual property rights in 
certain foreign jurisdictions. The legal systems of some countries, particularly developing countries, do not favor the 
enforcement of patents and other intellectual property protection, especially those relating to biotechnology and 
pharmaceuticals. For example, a 2024 report from the Office of the U.S. Trade Representative identified a number of 
countries, including India and China, where challenges to the procurement and enforcement of patent rights have been 
reported. Several countries, including India and China, have been listed in the report every year since 1989. This could 
make it difficult for us to stop the infringement of our patents, if obtained, or the misappropriation of our other intellectual 
property rights in such jurisdictions. Many foreign countries have compulsory licensing laws under which a patent owner 
must grant licenses to third parties. In addition, many countries limit the enforceability of patents against third parties, 
including government agencies or government contractors. In these countries, patents may provide limited or no benefit. 
Patent protection must ultimately be sought on a country-by-country basis, which is an expensive and time-consuming 
process with uncertain outcomes. Accordingly, we may choose not to seek patent protection in certain countries, and we 
will not have the benefit of patent protection in such countries.
Furthermore, proceedings to enforce our patent rights in foreign jurisdictions could, among other things, result in 
substantial costs and divert our efforts and attention from other aspects of our business, could put our patents at risk of 
being invalidated or interpreted narrowly, could put our patent applications at risk of not issuing and could provoke third 
parties to assert claims against us. We may not prevail in any lawsuits that we initiate and the damages or other remedies 
awarded, if any, may not be commercially meaningful. Accordingly, our efforts to enforce our intellectual property rights 
around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we 
develop or license.
For certain of our products and product candidates, we are dependent on licensed intellectual property. If we were to 
lose our rights to licensed intellectual property, we may not be able to continue developing or commercializing certain 
of our products or product candidates, if approved. If we breach any of the agreements under which we license the use, 
development and commercialization rights to our products, product candidates or technology from third parties or, in 
certain cases, we fail to meet certain development deadlines, we could lose license rights that are important to our 
business.
We are a party to a number of license agreements under which we are granted rights to intellectual property that are 
important to our business and we expect that we may need to enter into additional license agreements in the future. Our 
existing license agreements impose, and we expect that future license agreements will impose on us, various development, 
regulatory and/or commercial diligence obligations, payment of milestones and/or royalties and other obligations. If we 
fail to comply with our obligations under these agreements, or we are subject to a bankruptcy, the licensor may have the 
right to terminate the license, in which event we would not be able to market products covered by the license. Our 
business could suffer, for example, if any current or future licenses terminate, if the licensors fail to abide by the terms of 
the license, if the licensed patents or other rights are found to be invalid or unenforceable, or if we are unable to enter into 
necessary licenses on acceptable terms.
As we have done previously, we may need to obtain licenses from third parties to advance our research or allow 
commercialization of our product candidates, and we cannot provide any assurances that third-party patents do not exist 
that might be enforced against our current product candidates or future products in the absence of such a license. We may 

76
fail to obtain any of these licenses on commercially reasonable terms, if at all. Even if we are able to obtain a license, it 
may be non-exclusive, thereby giving our competitors access to the same technologies licensed to us. If we fail to obtain a 
license, we may be required to expend significant time and resources to develop or license replacement technology. If we 
are unable to do so, we may be unable to develop or commercialize the affected product candidates, which could 
materially harm our business and the third parties owning such intellectual property rights could seek either an injunction 
prohibiting our sales, or, with respect to our sales, an obligation on our part to pay royalties and/or other forms of 
compensation.
Licensing of intellectual property is of critical importance to our business and involves complex legal, business and 
scientific issues. Disputes may arise between us and our licensors regarding intellectual property subject to a license 
agreement, including:
•
the scope of rights granted under the license agreement and other interpretation-related issues;
•
whether and the extent to which our technology and processes infringe on intellectual property of the licensor 
that is not subject to the licensing agreement;
•
our right to sublicense patent and other rights to third parties under licenses or collaborative development 
relationships;
•
our diligence obligations with respect to the use of the licensed technology in relation to our development and 
commercialization of our product candidates, and what activities satisfy those diligence obligations; and
•
the ownership of inventions and know-how resulting from the joint creation or use of intellectual property by 
our licensors and us and our partners.
If disputes over intellectual property that we have licensed prevent or impair our ability to maintain our current 
licensing arrangements on acceptable terms, we may be unable to successfully commercialize the relevant product or to 
successfully develop and commercialize the affected product candidates.
We have entered into several licenses to support our various programs. We may enter into additional licenses to 
third-party intellectual property that are necessary or useful to our business. Our current licenses and any future licenses 
that we may enter into impose various royalty payment, milestone, and other obligations on us. For example, the licensor 
may retain control over patent prosecution and maintenance under a license agreement, in which case, we may not be able 
to adequately influence patent prosecution or prevent inadvertent lapses of coverage due to failure to pay maintenance 
fees. If we fail to comply with any of our obligations under a current or future license agreement, the licensor may allege 
that we have breached our license agreement, and may accordingly seek to terminate our license. In addition, future 
licensors may decide to terminate their licenses with us at will. Termination of any of our current or future licenses could 
result in our loss of the right to use the licensed intellectual property, which could materially adversely affect our ability to 
develop a product candidate or commercialize a product, as well as harm our competitive business position and our 
business prospects.
In addition, if our licensors fail to abide by the terms of the license, if the licensors fail to prevent infringement by 
third parties, if the licensed patents or other rights are found to be invalid or unenforceable, or if we are unable to enter 
into necessary licenses on acceptable terms, our business could materially suffer.
Some intellectual property which we have licensed, or may in the future license, may have been discovered through 
government-funded programs and thus may be subject to federal regulations such as “march-in” rights, certain 
reporting requirements, and a preference for U.S. industry. Compliance with such regulations may limit our exclusive 
rights, subject us to expenditure of resources with respect to reporting requirements, and limit our ability to contract 
with non-U.S. manufacturers.
Some of the intellectual property rights we have licensed, or may in the future license, may have been generated 
through the use of U.S. government funding and may therefore be subject to certain federal regulations. For example, 
some of the intellectual property rights licensed to us under the license agreement with The Regents of the University of 
California may have been generated using U.S. government funds. As a result, the U.S. government may have certain 
rights to intellectual property embodied in our current product or current or future product candidates pursuant to the 
Bayh-Dole Act of 1980, or Bayh-Dole Act. These U.S. government rights in certain inventions developed under a 

77
government-funded program include a non-exclusive, non-transferable, irrevocable worldwide license to use inventions 
for any governmental purpose. In addition, the U.S. government has the right to require us to grant exclusive, partially 
exclusive, or non-exclusive licenses to any of these inventions to a third party if the government determines that: (i) 
adequate steps have not been taken to commercialize the invention; (ii) government action is necessary to meet public 
health or safety needs; or (iii) government action is necessary to meet requirements for public use under federal 
regulations (also referred to as “march-in rights”). The U.S. government also has the right to take title to these inventions 
if we fail, or the applicable licensor fails, to disclose the invention to the government and/or file an application to register 
the intellectual property within specified time limits. In addition, the U.S. government may acquire title to these 
inventions in any country in which a patent application is not filed within specified time limits. Intellectual property 
generated under a government-funded program is also subject to certain reporting requirements, compliance with which 
may require us, or the applicable licensor, to expend substantial resources. In addition, the U.S. government requires that 
any products embodying the subject invention or produced through the use of the subject invention be manufactured 
substantially in the U.S. The manufacturing preference requirement can be waived if the owner of the intellectual property 
can show that reasonable but unsuccessful efforts have been made to grant licenses on similar terms to potential licensees 
that would be likely to manufacture substantially in the U.S. or that under the circumstances domestic manufacture is not 
commercially feasible. This preference for U.S. manufacturers may limit our ability to contract with non-U.S. product 
manufacturers for products covered by such intellectual property.
If we enter into future arrangements involving government funding, and we discover compounds or product 
candidates as a result of such funding, intellectual property rights to such discoveries may be subject to the applicable 
provisions of the Bayh-Dole Act.
If we do not obtain new chemical entity or other types of marketing and data exclusivity for our product candidates and 
if we do not obtain additional protection under the Drug Price Competition and Patent Term Restoration Act of 1984, 
commonly referred to as the Hatch-Waxman Act, and similar foreign legislation by extending the patent terms of our 
product candidates, our business may be materially harmed.
Marketing exclusivity provisions under the Federal Food, Drug, and Cosmetic Act, or FDCA, can delay the 
submission or the approval of certain marketing applications by other companies for a product with the same active 
moiety as a product we sell or may in the future sell. The FDCA provides a five-year period of non-patent marketing 
exclusivity within the U.S. to the first applicant to obtain approval of an NDA for a new chemical entity, or NCE. During 
the exclusivity period, the FDA may not accept for review an abbreviated new drug application, or ANDA, or a 505(b)(2) 
NDA submitted by another company for another drug based on the same active moiety, regardless of whether the drug is 
intended for the same indication as the original innovator drug or for another indication, where the applicant does not own 
or have a legal right of reference to all the data required for approval. However, an application may be submitted after 
four years if it contains a certification of patent invalidity or non-infringement to one of the patents listed with the FDA by 
the innovator NDA holder. The FDCA also provides three years of marketing exclusivity for a full NDA, or supplement to 
an existing NDA, if new clinical investigations, other than bioavailability studies, that were conducted or sponsored by the 
applicant are deemed by the FDA to be essential to the approval of the application (e.g., new indications, dosages or 
strengths of an existing drug). This three-year exclusivity covers only the modification for which the drug received 
approval on the basis of the new clinical investigations and does not prohibit the FDA from approving ANDAs for drugs 
containing the active agent for the original indication or condition of use. We have obtained NCE exclusivity for 
brexanolone and zuranolone and plan to seek NCE exclusivity for our current and future product candidates. The NCE 
exclusivity for brexanolone expired in June 2024, five years following approval of ZULRESSO. Lipocine, Inc. is 
currently developing LPCN 1154, an oral formulation of brexanolone, under the streamlined 505(b)(2) regulatory 
pathway, which allows for potential approval of an abbreviated NDA by the FDA. There is no guarantee that our product 
candidates will qualify for marketing or data exclusivity under these provisions or that such exclusivity for any of our 
products will alone be sufficient for our business. The applicable five-year and three-year exclusivity periods of NCE or 
data exclusivity under the FDCA will not delay the submission or approval of a full NDA. 
Depending upon the timing, duration and specifics of FDA marketing approval of our product candidates, one or 
more of the U.S. patents we own or license may be eligible for limited patent term restoration in the future under the 
Hatch-Waxman Act. The Hatch-Waxman Act permits a patent restoration term of up to five years as compensation for 
patent term lost during product development and the FDA regulatory review process. Even if, at the relevant time, we 
have a valid issued patent covering our product, we may not be granted an extension if we were to fail to satisfy 
applicable requirements. Moreover, the applicable time period or the scope of patent protection afforded could be less 

78
than we request. If we are unable to obtain patent term extension or restoration or the term of any such extension is less 
than we request, and we do not have any other exclusivity, our competitors may obtain approval of competing products 
following our patent expiration and our business, financial condition or results of operations could be adversely affected. 
Changes in U.S. patent law could diminish the value of patents in general, thereby impairing our ability to protect our 
products.
Our success is heavily dependent on intellectual property, particularly patents. Obtaining and enforcing patents in 
the biotechnology industry involves both technological and legal complexity, and is therefore costly, time-consuming and 
inherently uncertain. In addition, the U.S. has recently enacted wide-ranging patent reform legislation: the Leahy-Smith 
America Invents Act, referred to as the America Invents Act. The America Invents Act includes a number of significant 
changes to U.S. patent law. These include provisions that affect the way patent applications are prosecuted and may also 
affect patent litigation. It is not yet clear what, if any, impact the America Invents Act will have on the operation of our 
business. However, the America Invents Act and its implementation could increase the uncertainties and costs 
surrounding the prosecution of our patent applications and the enforcement or defense of any patents that may issue from 
our patent applications, all of which could have a material adverse effect on our business and financial condition.
In addition, U.S. Supreme Court rulings have narrowed the scope of patent protection available in certain 
circumstances and weakened the rights of patent owners in certain situations. For example, in March 2012, in Mayo 
Collaborative Services, DBA Mayo Medical Laboratories, et al. v. Prometheus Laboratories, Inc., the U.S. Supreme 
Court held that several claims drawn to measuring drug metabolite levels from patient samples and correlating them to 
drug doses were not patentable subject matter. The decision appears to impact diagnostics patents that merely apply a law 
of nature via a series of routine steps and it has created uncertainty around the ability to obtain patent protection for 
certain inventions. Additionally, in June 2013, in Association for Molecular Pathology v. Myriad Genetics, Inc., the U.S. 
Supreme Court held that claims to isolated genomic DNA are not patentable, but claims to complementary DNA 
molecules are patent eligible because they are not a natural product. In June 2014, in Alice Corporation Pty. Ltd. v. CLS 
Bank International, et al., a case involving patent claims directed to a method for mitigating settlement risk, the U.S. 
Supreme Court held that the patent eligibility of claims directed to abstract ideas, products of nature, and laws of nature 
should be determined using the same framework set forth in Prometheus. The U.S. PTO has issued a set of guidelines 
setting forth procedures for determining subject matter eligibility of claims directed to abstract ideas, products of nature, 
and laws of nature in line with the Prometheus, Myriad, and Alice decisions. The guidance does not limit the application 
of Myriad to DNA but, rather, applies the decision to other natural products. The full impact of these decisions on our 
business is not yet known.
In May 2023, the Supreme Court, in Amgen Inc. v. Sanofi, et al., held that claims to a functionally-defined genus of 
monoclonal antibodies were invalid due to a lack of enablement, as they failed to provide adequate guidance for making 
and using the claimed antibodies. The Supreme Court noted that the general principle remains that all claims must be 
enabled to their “full scope” and that broader claims require more enablement.
In addition to increasing uncertainty with regard to our ability to obtain future patents, this combination of events 
has created uncertainty with respect to the value of patents, once obtained. Depending on these and other decisions by the 
U.S. Congress, the federal courts and the U.S. PTO, the laws and regulations governing patents, including patent terms, 
could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce any patents that 
may issue in the future.
With passage of the CREATES Act, we are exposed to possible litigation and damages by competitors. In addition, 
existing statutes, including the CREATES Act, and proposed legislation in Congress, if passed into law, could limit the 
patent exclusivity on our products or facilitate earlier entry of generic competition.
Under the CREATES Act, legislation intended to facilitate the development of generic and biosimilar products, we 
are exposed to possible litigation and damages by competitors who may claim that we are not providing sufficient 
quantities of our approved products on commercially reasonable, market-based terms for testing in support of their 
ANDAs and 505(b)(2) applications. Such litigation would subject us to litigation costs, damages and reputational harm, 
which could lead to lower revenues. Increased risk of generic competition with ZURZUVAE and any of our product 
candidates, if approved, including as a result of the CREATES Act, could impact our ability to maximize product revenue.

79
In addition, members of Congress have proposed numerous legislative initiatives aimed at limiting the patent 
exclusivity on drug products or facilitating earlier entry of generic versions of approved drugs. Examples of bills that have 
been proposed include a bill that, if passed, would create a presumption of invalidity for patents beyond the first patent 
covering a drug product thus shifting the burden to the innovator to prove that these subsequent patents are separately 
patentable inventions, distinct from the first patent; a bill that, if passed, would empower the Federal Trade Commission 
to investigate whether large patent portfolios covering a drug product constitute an anti-competitive practice and to file 
antitrust lawsuits in such instances; and a bill that, if passed, would limit the availability of a 30-month stay on approval 
by the FDA of a generic version of a drug to only those instances where the ANDA litigation involves a composition of 
matter patent claiming the drug substance. Such legislation, if passed into law, could adversely affect ZURZUVAE or any 
future products or product candidates or result in earlier entry into the market of generic versions of our drugs.
Risks Related to our Industry
Healthcare regulations aimed at reducing healthcare costs may have a material adverse effect on our business or 
results of operations. 
There have been, and likely will continue to be, legislation and legislative, administrative and regulatory proposals 
in the U.S., both at the federal and state level, and in many foreign jurisdictions, aimed at reducing healthcare costs. The 
implementation of cost containment measures, drug pricing controls or other reforms could have an adverse effect on our 
revenue from ZURZUVAE or from the sales of any other future products that are successfully developed and approved, 
and may limit our ability to achieve profitability.
For example, the ACA substantially changed the way healthcare is financed by both governmental and private 
insurers, and significantly impacted the U.S. pharmaceutical industry. The ACA, among other things, subjects biological 
products to potential competition by lower-cost biosimilars, provided a new methodology by which rebates owed by 
manufacturers under the Medicaid Drug Rebate Program are calculated for drugs that are inhaled, infused, instilled, 
implanted or injected, increased the minimum Medicaid rebates owed by manufacturers under the Medicaid Drug Rebate 
Program and extended the rebate program to individuals enrolled in Medicaid managed care organizations, established 
annual fees and taxes on manufacturers of certain branded prescription drugs, and created a new Medicare Part D 
coverage gap discount program, in which manufacturers must agree to offer 70% (pursuant to the Bipartisan Budget Act 
of 2018, effective as of 2019) point-of-sale discounts off negotiated prices of applicable brand drugs to eligible 
beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs to be covered under 
Medicare Part D (subsequently modified by the Inflation Reduction Act of 2022, or IRA, as discussed below).
The Budget Control Act of 2011, among other things, created measures for spending reductions by Congress. A 
Joint Select Committee on Deficit Reduction, tasked with recommending a targeted deficit reduction of at least $1.2 
trillion for the years 2013 through 2021, was unable to reach required goals, thereby triggering the legislation’s automatic 
reduction to several government programs. These changes included aggregate reductions to Medicare payments to 
providers of up to 2% per fiscal year, which went into effect in April 2013 and will remain in effect through 2031. 
Pursuant to the Coronavirus Aid, Relief and Economic Security Act and subsequent legislation, these Medicare sequester 
reductions were reduced and suspended, with the current 2% rate of sequestration resuming in July 2022. The rate of 
sequestration is currently set at 2%, will increase to 2.25% for the first half of fiscal year 2030, to 3% for the second half 
of fiscal year 2030, and to 4% for the remainder of the sequestration period that lasts through the first six months of fiscal 
year 2031. These and other laws may result in additional reductions in Medicare and other healthcare funding and 
otherwise affect the prices we may obtain for any of our products or product candidates for which we may obtain 
regulatory approval or the frequency with which any such product is prescribed or used.
Certain provisions of the ACA have been subject to judicial challenges as well as efforts to modify them or to alter 
their interpretation or implementation. For example, the U.S. Tax Cuts and Jobs Act of 2017 included a provision 
repealing the tax-based shared responsibility payment imposed by the ACA 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.” We expect 
that the ACA, its implementation, efforts to challenge or modify the ACA or its implementing regulations, or portions 
thereof, and other healthcare reform measures that may be adopted in the future, could have a material adverse effect on 
our industry generally and on our ability to commercialize our products and product candidates, if approved.

80
There has been increasing legislative and enforcement interest in the U.S. with respect to drug pricing practices. 
Specifically, there have been several U.S. Congressional inquiries and proposed and enacted federal and state legislation 
designed to, among other things, bring more transparency to drug pricing; reduce the cost of prescription drugs, including 
under Medicare and Medicaid, which may potentially impact negotiations on pricing and discounts with commercial 
payors; review the relationship between pricing and manufacturer patient programs; and reform government program 
reimbursement methodologies for drugs. There have been multiple Congressional and administrative efforts to address 
drug pricing, including the IRA. It is unclear whether any other legislation or public policy will come to pass, and if so, 
what effect it could have on our business. 
The IRA has implications for Medicare Part D, which is a program available to individuals who are entitled to 
Medicare Part A or enrolled in Medicare Part B to give them the option of paying a monthly premium for certain 
outpatient prescription drug coverage, as well as Medicare Part B. Among other things, the IRA requires manufacturers of 
certain drugs to engage in price negotiations with Medicare, with negotiated prices subject to a cap and first set to take 
effect in 2026; imposes rebates under Medicare Part B and Medicare Part D to penalize price increases that outpace 
inflation (the first Part B inflation rebate period was in the first quarter of 2023; the first Part D inflation rebate period was 
the fourth quarter of 2022 through the third quarter of 2023); and replaces the Part D coverage gap discount program with 
a new Part D discounting program, which began in 2025. The IRA permits the Secretary of HHS to implement many of 
these provisions through guidance, as opposed to regulation, for the initial years of these programs. Manufacturers may be 
subject to civil monetary penalties for certain violations of the negotiation and inflation rebate provisions and an excise 
tax during a noncompliance period under the negotiation program. 
Specifically, with respect to price negotiations, Congress authorized CMS to negotiate lower prices for certain costly 
single-source drug and biologic products that do not have competing generics or biosimilars and are reimbursed under 
Medicare Part B and Part D. CMS may negotiate prices for ten high-cost drugs paid for by Medicare Part D starting in 
2026, followed by 15 Part D drugs in 2027, 15 Part B or Part D drugs in 2028, and 20 Part B or Part D drugs in 2029 and 
beyond. Drugs may be selected for negotiation only once they are at least seven years post-approval (such that they will 
be nine years post-approval when first subject to the maximum negotiated price) and biologics may be selected for 
negotiation 11 years post approval (such that they will be 13 years post-approval when first subject to the maximum 
negotiated price). It does not apply to drugs and biologics that have orphan drug designation and have been approved for a 
single rare disease or condition. We could be at risk of government action for any noncompliance with the price 
negotiation program if, in the future, any of our products are the subject of Medicare price negotiations. In that event, the 
outcome of the Medicare price negotiations, which will be made publicly available, may also impact negotiations on 
pricing and discounts with commercial payors. 
The first cycle of negotiations for the Medicare Drug Price Negotiation Program commenced in the summer of 
2023. On August 15, 2024, HHS published the results of the first Medicare drug price negotiations for ten selected drugs 
that treat a range of conditions, including diabetes, chronic kidney disease, and rheumatoid arthritis. The prices of these 
ten drugs are scheduled to become effective January 1, 2026. On January 17, 2025, CMS announced its selection of 15 
additional drugs covered by Part D for the second cycle of negotiations by February 1, 2025. While there had been some 
questions about the Trump Administration’s position on this program, CMS issued a public statement on January 29, 
2025, declaring that lowering the cost of prescription drugs is a top priority of the new administration and CMS is 
committed to considering opportunities to bring greater transparency in the negotiation program. The second cycle of 
negotiations with participating drug companies will occur during 2025, and any negotiated prices for this second set of 
drugs will be effective starting January 1, 2027.
These risks as to pricing may further heighten the risk that we would not be able to achieve the expected return on 
our drug products or full value of our patents protecting our products if the pricing of any of our products are the subject 
of Medicare price negotiations. As a result, these risks may also impact the development decisions we make with respect 
to our products and product candidates, including zuranolone.
Further, the IRA subjects drug manufacturers to civil monetary penalties and a potential excise tax for failing to 
comply with the IRA by offering a price that is not equal to or less than the negotiated “maximum fair price” under the 
law. The IRA also requires manufacturers to pay rebates for drugs reimbursed under Medicare Part B or Part D whose 
price increases exceed inflation and caps Medicare Part D out-of-pocket drug costs beginning in 2025, at $2,000 a year, 
subject to an adjustment for inflation thereafter. Drug manufacturers may also be subject to civil monetary penalties with 
respect to their compliance with these programs. 

81
It is unclear how the IRA will be implemented. Several pharmaceutical companies, as well as the U.S. Chamber of 
Commerce, and the Pharmaceutical Research and Manufacturers of America, or PhRMA, have filed lawsuits against HHS 
and CMS asserting that, among other things, the IRA’s drug price negotiation program for Medicare constitutes an 
uncompensated taking in violation of the Fifth Amendment of the U.S. Constitution and is otherwise unlawful. HHS has 
generally won the substantive disputes in these cases, and various federal district court judges have expressed skepticism 
regarding the merits of the legal arguments being pursued by the pharmaceutical industry. Certain of these cases are now 
on appeal and, on October 30, 2024, the U.S. Court of Appeals for the Third Circuit heard oral argument in three of these 
cases. We expect that litigation involving these and other provisions of the IRA will continue, with unpredictable and 
uncertain results. We further cannot predict with certainty what impact the IRA or any other federal or state health 
reforms will have on us, but such changes could impose new or more stringent regulatory requirements on our activities or 
result in reduced reimbursement for our products, any of which could adversely affect our business, results of operations 
and financial condition. There may be additional Congressional and administrative efforts to address drug pricing.
At the state level, legislatures have increasingly passed legislation and agencies have implemented regulations 
designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, 
discounts, restrictions on certain product access and marketing cost disclosure and price transparency measures, and, in 
some cases, designed to encourage importation from other countries and bulk purchasing. Additionally, some individual 
states have begun establishing Prescription Drug Affordability Boards, or PDABs, to conduct affordability reviews for 
certain drugs, including high-cost drugs and drugs with qualifying price increases. In some states, the PDAB has authority 
to set upper payment limits on what certain purchasers and payers may pay or reimburse for drugs that are found to pose 
an affordability challenge in the state. If one of our products is selected for an affordability review and subject to an upper 
payment limit by a PDAB, it could have a material adverse effect on our ability to commercialize the product and achieve 
the full value of our patents. 
In addition, in October 2020, the HHS and the FDA published a final rule allowing states and other entities to 
develop a Section 804 Importation Program to import certain prescription drugs from Canada into the U.S. That regulation 
was challenged in a lawsuit by PhRMA, but the case was dismissed by a federal district court in February 2023 after the 
court found that PhRMA did not have standing to sue the HHS. Seven states (Colorado, Florida, Maine, New Hampshire, 
New Mexico, Texas and Vermont) have passed laws allowing for the importation of drugs from Canada. North 
Dakota and Virginia have passed legislation establishing workgroups to examine the impact of a state importation 
program. As of October 2024, five states (Colorado, Florida, Maine, New Hampshire and New Mexico) had submitted 
Section 804 Importation Program proposals to the FDA. Vermont has submitted a concept letter to the HHS. On January 
5, 2024, the FDA approved Florida’s plan for Canadian drug importation. Florida now has authority to import certain 
drugs from Canada for a period of two years once certain conditions are met. Florida will first need to submit a pre-import 
request for each drug selected for importation, which must be approved by the FDA. The state will also need to relabel the 
drugs and perform quality testing of the products to meet FDA standards.
There have been, and likely will continue to be, legislative and regulatory proposals at the foreign, federal and state 
levels directed at containing or lowering the cost of healthcare or limiting exclusivity periods for pharmaceutical products. 
We cannot predict the initiatives that may be adopted in the future. The continuing efforts of the government, insurance 
companies, managed care organizations and other payors of healthcare services to contain or reduce costs of healthcare 
and/or impose price controls may adversely affect:
•
the demand for ZURZUVAE or any of our product candidates, if approved;
•
our ability to receive or set a price that we believe is fair for our products;
•
our ability to generate revenue and achieve or maintain profitability;
•
the amount of taxes that we are required to pay; and
•
the availability of capital.
We expect that the measures discussed above, as well as other healthcare reform measures that may be adopted in 
the future, may result in additional reductions in Medicare and other healthcare funding, more rigorous coverage criteria, 
lower reimbursement, and new payment methodologies. This could lower the price that we receive for any approved 
product. Any denial in coverage or reduction in reimbursement from Medicare or other government-funded programs may 
result in a similar denial or reduction in payments from private payors, which may prevent us from being able to generate 

82
sufficient revenue from sales of ZURZUVAE, successfully commercialize any other products if approved in the future, 
and achieve profitability.
Our internal computer systems or networks or cloud platforms, or those of our collaborators, our third-party CROs or 
our other contractors, consultants or service providers, may fail or suffer security breaches, which could result in a 
material disruption of our development programs, compromise personal or sensitive information related to our 
business, or cause us to incur significant liabilities which could adversely impact our business. 
We are increasingly dependent upon information technology systems, infrastructure and data to operate our 
business. Despite the implementation of security measures, our internal computer systems and those of our collaborators, 
our third-party CROs and our other contractors, consultants and service providers are vulnerable to cyber security threats, 
including damage from unauthorized access, theft, natural disasters, terrorism, war, telecommunication and electrical 
failures, and system malfunction, or from cyber-attacks by malicious third parties (including the deployment of harmful 
malware, ransomware, viruses, worms, denial-of-service attacks, supply chain attacks, social engineering schemes and 
other means to affect service reliability and threaten the confidentiality, integrity and availability of information). In 
addition, cyber-attacks against us or against third parties we do business with could also utilize phishing attempts, email 
fraud, or attempts to cause payments, confidential or sensitive information, or other data to be transmitted to an 
unintended recipient, and could include the use of artificial intelligence, or AI, and machine learning to launch more 
automated, targeted and coordinated attacks. If such an event were to occur and cause interruptions in our operations, it 
could result in a material disruption of our programs or cause us to have liability for disclosure of personal information of 
our customers. For example, the loss of clinical trial data for our product candidates could result in delays in our 
regulatory submission and approval efforts and significantly increase our costs to recover or reproduce the data, if 
possible. To the extent that any disruption, disaster or security breach results in a loss of or damage to our data or 
applications or other data or applications relating to our technology or product candidates, or inappropriate disclosure of 
confidential or proprietary information, we could incur liabilities and the further development of our product candidates 
could be delayed or prevented.
Moreover, as AI and machine learning technologies evolve and their use increases, we will need to invest in 
resources to ensure appropriate development and use of any generative AI, or similar technologies, and to develop internal 
compliance policies and procedures addressing this use, including in response to laws and regulations that may be adopted 
or interpreted to address these technologies, such as the EU AI Act. Our potential future use and/or development of AI, if 
applicable, could place us under increased regulatory oversight, exacerbate our risks related to litigation and intellectual 
property, and augment our existing obligations regarding information security.
We could be required to expend significant amounts of money and other resources to respond to these threats or 
breaches and to repair or replace information systems or networks or cloud platforms. We also could suffer financial loss 
or the loss of valuable confidential information. In addition, we could be subject to regulatory actions and/or claims made 
by individuals and groups in private litigation involving privacy issues related to data collection and use practices and 
other data privacy laws and regulations, including claims for misuse or inappropriate disclosure of data, as well as unfair 
or deceptive acts or practices in violation of Section 5(a) of the Federal Trade Commission Act, or the FTC Act. The 
Federal Trade Commission, or the FTC, expects a company’s data security measures to be reasonable and appropriate in 
light of the sensitivity and volume of consumer information it holds, the size and complexity of its business, and the cost 
of available tools to improve security and reduce vulnerabilities. Individually identifiable health information is considered 
sensitive data that merits stronger safeguards. The guidance of the FTC for appropriately securing consumers’ personal 
information is similar to what is required by the HIPAA Security Rule, which establishes national standards for covered 
entities to protect individuals’ electronic personal health information. The HIPAA Security Rule requires covered entities 
to have appropriate administrative, physical and technical safeguards to help ensure the confidentiality, integrity, and 
security of electronic protected health information. With respect to privacy, the FTC also sets expectations that companies 
honor the privacy promises made to individuals about how the company handles consumers’ personal information. Any 
failure to honor promises, such as the statements made in a privacy policy or on a website, may also constitute unfair or 
deceptive acts or practices in violation of the FTC Act. The FTC is also actively expanding its authority under the 
“unfairness” prong of Section 5 of the FTC Act through its recent enforcement actions and is especially focused on health 
data. While we do not intend to engage in unfair or deceptive acts or practices, the FTC has the power to enforce promises 
as it interprets them, and events that we cannot fully control, such as data breaches, may result in FTC enforcement. 
Enforcement by the FTC under the FTC Act can result in civil penalties or enforcement actions. 

83
 Although we develop and maintain systems and controls designed to prevent these events from occurring and we 
have a process to identify and mitigate threats, the development and maintenance of these systems, controls and processes 
are costly and require ongoing monitoring and updating as technologies change and efforts to overcome security measures 
become increasingly sophisticated. Moreover, we cannot guarantee that our, or our third-party CROs’ or our other 
contractors’, consultants’ or service providers’ security measures will be sufficient to prevent data loss and other security 
breaches. Despite our efforts, the possibility of these events occurring cannot be eliminated entirely and there can be no 
assurance that any measures we take will prevent cyber-attacks or security breaches that could adversely affect our 
business, including security breaches that may remain undetected for extended periods of time, which can substantially 
increase the potential for a material adverse impact resulting from the breach. 
Inadequate funding for the FDA, the SEC and other government agencies, including from government shutdowns, or 
other disruptions to these agencies’ operations, could hinder their ability to hire and retain key leadership and other 
personnel, prevent new products from being developed or commercialized in a timely manner or otherwise prevent 
those agencies from performing normal business functions on which the operation of our business may rely, which 
could negatively impact our business. 
The ability of the FDA to review and approve new products can be affected by a variety of factors, including 
government budget and funding levels, ability to hire and retain key personnel and accept the payment of user fees, and 
statutory, regulatory and policy changes. Average review times at the Agency have fluctuated in recent years as a result. 
Disruptions at the FDA and other agencies may delay the availability or responsiveness of regulators throughout the 
development process, which could negatively impact our ability to advance our programs. For example, such disruptions 
could slow the time necessary for new product candidates to be reviewed and/or approved by necessary government 
agencies, which would adversely affect our business. In addition, government funding of the SEC and other government 
agencies on which our operations may rely, including those that fund research and development activities, is subject to the 
political process, which is inherently fluid and unpredictable.
In addition, disruptions may result from events similar to the COVID-19 pandemic. During the COVID-19 
pandemic, a number of companies announced receipt of complete response letters due to the FDA’s inability to complete 
required inspections for their applications. In the event of a similar public health emergency in the future, the FDA may 
not be able to continue its current pace and review timelines could be extended. Regulatory authorities outside the U.S. 
facing similar circumstances may adopt similar restrictions or other policy measures in response to a similar public health 
emergency and may also experience delays in their regulatory activities. 
Disruptions at the FDA and other agencies may also slow the time necessary for new product candidates to be 
reviewed and/or approved by necessary government agencies, which would adversely affect our business. For example, 
over the last several years the U.S. government has shut down several times and certain regulatory agencies, such as the 
FDA and the SEC, have had to furlough critical employees and stop critical activities. If a prolonged government 
shutdown occurs, it could significantly impact the ability of the FDA to timely review and process our regulatory 
submissions, which could have a material adverse effect on our business. Further, future government shutdowns could 
impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue 
our operations. 
Our employees, independent contractors, consultants, collaborators and vendors may engage in misconduct or 
other improper activities, including non-compliance with regulatory standards and/or requirements and insider 
trading, which could cause significant liability for us and harm our reputation. 
We are exposed to the risk of fraud or other misconduct by our employees, independent contractors, consultants, 
collaborators and vendors. Misconduct by these partners could include intentional, reckless and/or negligent conduct or 
unauthorized activities that violate FDA regulations or similar regulations of comparable foreign regulatory authorities; 
provide inaccurate information to the FDA or comparable foreign regulatory authorities; fail to comply with 
manufacturing standards, federal and state healthcare fraud and abuse laws and regulations and similar laws and 
regulations established and enforced by comparable foreign regulatory authorities; fail to comply with state drug pricing 
transparency filing requirements; fail to report financial information or data accurately; or fail to disclose unauthorized 
activities to us. Employee misconduct could also involve the improper use of information obtained in the course of 

84
clinical trials, which could result in regulatory sanctions and serious harm to our reputation. This could include violations 
of HIPAA, other U.S. federal and state laws, and requirements of foreign jurisdictions, including the GDPR. We are also 
exposed to risks in connection with any insider trading violations by employees or others affiliated with us. It is not 
always possible to identify and deter employee or third-party misconduct, and the precautions we take to detect and 
prevent these activities may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from 
significant penalties, governmental investigations or other actions or lawsuits stemming from a failure to be in compliance 
with such laws, standards, regulations, guidance or codes of conduct. If any such actions are instituted against us, and we 
are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our 
business and results of operations, including the imposition of significant fines or other sanctions.
Risks Related to Our Financial Position and Need for Capital
We are a biopharmaceutical company that has not generated significant revenue to date. We have incurred significant 
operating losses since our inception and anticipate that we will incur losses for the foreseeable future.
We are a biopharmaceutical company with only one approved product being commercialized, and we only began 
generating revenue from product sales in the second quarter of 2019. Biopharmaceutical product development and 
commercialization are highly speculative undertakings and involve a substantial degree of risk. 
We have funded our operations to date primarily through proceeds from sales of common stock, including the sale of 
stock to Biogen MA Inc., or BIMA; redeemable convertible preferred stock prior to our initial public offering and, to a 
lesser extent, the issuance of convertible notes. From our inception through December 31, 2024, we had received 
aggregate net proceeds of $2.8 billion from such transactions. We also received $1.0 billion in upfront payments under our 
collaborations with Biogen and Shionogi and received a milestone payment under the collaboration agreement with 
Biogen totaling $75.0 million for the first commercial sale of ZURZUVAE for the treatment of women with PPD. As of 
December 31, 2024, our cash, cash equivalents and marketable securities were $504.4 million. We have incurred net 
losses in each year since our inception, except for net income of $606.1 million for the year ended December 31, 2020, 
reflecting revenue recognized under a collaboration and license agreement with Biogen. Our net loss was $400.7 million 
for the year ended December 31, 2024, and our accumulated deficit was $3.0 billion as of December 31, 2024.
Substantially all of our operating losses have resulted from costs incurred in connection with our research and 
development programs and from selling, general and administrative costs associated with our operations. We expect to 
continue to incur operating losses over the next several years and for the foreseeable future. Our prior losses, combined 
with expected future losses, have had, and will continue to have, an adverse effect on our stockholders’ equity and 
working capital. Although we expect that our operating expenses will decrease in 2025 as compared to 2024 as a result of 
our pipeline prioritization and anticipated cost savings from the October 2024 corporate reorganization, we expect to 
continue to incur significant operating expenses, particularly as we and our collaboration partner Biogen continue to 
commercialize ZURZUVAE in the U.S. for the treatment of women with PPD and as we continue work to advance 
ongoing and future product candidates. We expect these costs will include the costs and expenses associated with: our 
sales and marketing activities; conducting clinical trials of current and future product candidates; continuing certain 
research activities; outsourced manufacturing; pursuing potential business development activities; and the impact of future 
decisions and activities. If we receive marketing approval of any current or future product candidate beyond ZURZUVAE 
and ZULRESSO for the treatment of PPD, we will incur significant additional sales, marketing and manufacturing 
expenses. We incur significant legal and accounting costs associated with operating as a public company. Because of the 
numerous risks and uncertainties associated with developing pharmaceutical products, we are unable to predict the extent 
of any future losses or when we will become profitable, if at all. Even if we do become profitable, we may not be able to 
sustain or increase our profitability on a quarterly or annual basis.
Our ability to become profitable depends upon our ability to generate product revenue and/or revenue from our 
collaborations on a sustained basis. We began to generate revenue from product sales in the second quarter of 2019 in 
conjunction with launch of our product ZULRESSO, which commenced in June 2019. We discontinued commercial 
availability of ZULRESSO in the U.S. as of December 31, 2024, and as a result will no longer generate additional revenue 
from ZULRESSO. We began to generate revenue from sales of ZURZUVAE in December 2023. Our ability to generate 

85
significant product and collaboration revenues from our current products and any future approved product depends on a 
number of factors, including, but not limited to:
•
our ability to successfully commercialize, with Biogen, ZURZUVAE for the treatment of women with PPD in 
the U.S., including our ability to achieve and maintain satisfactory coverage and reimbursement and market 
acceptance among healthcare providers, patients and third-party payors;
•
our ability to successfully complete all ongoing and future clinical trials and non-clinical studies required to 
file for, and obtain, U.S. and foreign marketing approval for our current or future product candidates; and our 
ability to file for and receive marketing approval to commercialize our product candidates, if successfully 
developed; and
•
with respect to any product candidate potentially approved in the future, our ability, alone or with 
collaborators, to commercialize the product by developing and effectively deploying a sales force, and to 
achieve market acceptance and satisfactory coverage and reimbursement of such product among healthcare 
providers, patients and third-party payors.
If we are unable to generate significant product revenue and/or revenue from our current collaborations on a 
sustained basis, we will not become profitable, and may be unable to continue operations without continued funding.
We will need to raise additional funding, which may not be available on acceptable terms, or at all. Failure to obtain 
this necessary capital when needed may force us to delay, limit or terminate our product development efforts or other 
operations. Even if we believe we have sufficient funds for our current or future operating plans, we may seek 
additional capital if market conditions are favorable or in light of other strategic considerations. To the extent that we 
raise additional capital through the sale of common stock or securities convertible or exchangeable into common stock, 
the ownership interest of our stockholders in our company will be diluted.
We are currently commercializing ZURZUVAE for the treatment of women with PPD in the U.S. We are also 
advancing our prioritized pipeline of product candidates through non-clinical and clinical development. Commercializing 
products and developing additional small molecule products are expensive. In October 2024 and August 2023, we 
implemented strategic corporate reorganizations to support our goal of long-term business growth. Although we expect 
that our operating expenses will decrease in 2025 as compared to 2024 as a result of our pipeline prioritization and 
anticipated cost savings from the October 2024 corporate reorganization, we expect to continue to incur significant 
operating expenses, particularly as we and our collaboration partner Biogen continue commercialization of ZURZUVAE 
in the U.S. for the treatment of women with PPD. Our anticipated operating expenses include costs associated with: sales 
and marketing activities; manufacturing; clinical trials of our current and future product candidates; pursuing potential 
business development activities; continuation of certain research activities; and the impact of future decisions and 
activities. We will need to raise additional capital in the future to fund operating needs. Our cash needs will increase 
further if we choose to pursue additional indications and/or geographies for our product candidates, conduct additional 
clinical trials for indications we are already pursuing beyond the anticipated trials, identify new potential opportunities or 
otherwise expand our activities more rapidly than we presently anticipate.
As of December 31, 2024, our cash, cash equivalents and marketable securities were $504.4 million. Based upon our 
current operating plan, we anticipate that our existing cash, cash equivalents and marketable securities as of December 31, 
2024, together with anticipated funding from our ongoing collaborations and estimated revenues, excluding any potential 
milestone payments we may receive under our collaboration agreements, will support our operations to mid-2027. We 
have based this estimate on assumptions that may prove to be wrong, such as the revenue that we expect to realize from 
our collaboration agreement for the continued commercialization of ZURZUVAE. To the extent estimated revenue levels 
are not realized, we may adjust our operating plan accordingly, including the deferral or reduction of planned operating 
expenses, as needed. Our current operating plan does not contemplate other development activities we may pursue or that 
all of the currently planned activities will proceed at the same pace, or that all of the activities will be fully initiated or 
completed during that time. We may not achieve milestones tied to cash payments to us from our collaboration partners 
on the timelines we expect or at all, or generate anticipated revenues from sales of ZURZUVAE for the treatment of 
women with PPD at the levels or on the timelines we expect. We may use available capital resources sooner than we 
expect under our current operating plan, including as a result of unexpected events or changes in plans. We also may not 
achieve cost savings from our October 2024 corporate reorganization at the levels we expect. In addition, our operating 

86
plan may change. We may choose to seek additional funds through equity or debt financings, government or other third-
party funding, marketing and distribution arrangements and other collaborations, strategic alliances, licensing or royalty 
arrangements and arrangements involving other rights or a combination of these or other approaches. In any event, we 
anticipate we will require additional capital to fund our operations. If current or future economic conditions impact capital 
markets for an extended period, or if our business prospects are impaired or the capital markets disrupted for any other 
reason, additional capital may not be available to us on acceptable terms, or at all. Even if we believe we have sufficient 
funds for our current or future operating plans, we may seek additional capital if we believe market conditions are 
favorable or in light of other strategic considerations.
We cannot guarantee that future financing will be available in sufficient amounts or on terms acceptable to us, if at 
all. Any time we encounter a major setback in our development or regulatory activities, such as the CRL issued by the 
FDA related to our NDA for zuranolone for the treatment of MDD, or in our commercialization efforts, or receive 
negative data from a key clinical program, such as the announcement of negative results from the DIMENSION Study in 
November 2024, the LIGHTWAVE Study in October 2024, the PRECEDENT Study in April 2024, and the KINETIC 2 
Study in July 2024, our stock price is likely to decline, as it did in those instances, which would make a future financing 
more difficult and potentially more dilutive to our existing stockholders. In addition, future global economic uncertainty, 
reduced liquidity, capital market disruptions, and other macroeconomic or geopolitical conditions, including future 
banking crises, or pandemics and other health crises, may potentially make it more difficult for us to raise additional funds 
on favorable terms. Moreover, the terms of any financing may adversely affect the holdings or the rights of our 
stockholders. The issuance of additional securities, whether equity or debt, by us, or the possibility of such issuance, may 
cause the market price of our shares to decline. Failure to obtain capital if and when needed may force us to delay, limit or 
terminate our product development efforts or other operations, including the commercialization of any approved product. 
We could also be required to seek funds through arrangements with collaboration partners or otherwise at an earlier 
stage than otherwise would be desirable, and we may be required to relinquish rights to some of our technologies or 
product candidates or otherwise agree to terms unfavorable to us, any of which could have a material adverse effect on our 
business, operating results and prospects.
To the extent that we raise additional capital through the sale of common stock or securities convertible or 
exchangeable into common stock, the ownership interest of our stockholders in our company will be diluted. For example, 
in September, 2024, we entered into a Sales Agreement, or the ATM Sales Agreement, with TD Securities (USA) LLC, as 
sales agent, or TD Cowen, with respect to an “at the market offering” program pursuant to which we may offer and sell 
shares of our common stock having an aggregate offering price of up to $250.0 million, from time to time through TD 
Cowen. Any significant sales of shares of our common stock pursuant to the ATM Sales Agreement would result in 
dilution to our current stockholders. 
Debt financing, if available, would increase our fixed payment obligations and 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. The incurrence of indebtedness would result in increased fixed payment obligations, 
and we may be required to agree to certain restrictive covenants, such as limitations on our ability to incur additional debt, 
limitations on our ability to acquire, sell or license intellectual property rights, and other operating restrictions that could 
adversely impact our ability to conduct our business. If we raise additional funds through collaborations, strategic 
partnerships and licensing arrangements with third parties, we may have to relinquish valuable rights to our product 
candidates, our intellectual property, future revenue streams or grant licenses on terms that are not favorable to us.
If we are unable to obtain funding on a timely basis, we may be required to significantly curtail, delay or discontinue 
one or more of our research or development programs or the commercialization of any approved product, or be unable to 
expand our operations or otherwise capitalize on our business opportunities, as desired, which could materially affect our 
business, financial condition and results of operations.

Risks Related to Our Common Stock
Market volatility may cause our stock price, and the value of an investment in our stock, to fluctuate.
The market price for our common stock, similar to that of other biopharmaceutical companies, is volatile. The 
market price of our common stock may fluctuate significantly in response to a number of factors, most of which we 
cannot control, including, among others:
•
the results of our commercialization efforts with respect to ZURZUVAE in the U.S. as a treatment for women 
with PPD, and our ability to attain and maintain commercial success; 
•
developments related to the state of our collaborations, Biogen’s unsolicited, non-binding acquisition proposal, 
and our strategic review process;
•
plans for, progress of, timing of, changes to, delays in or the results from clinical trials or non-clinical studies 
of any of our products or product candidates, serious adverse events arising in the course of development or 
post-marketing, or any delays or major announcements related to such studies or trials; 
•
the success or failure of any regulatory activities with respect to our existing or future product candidates; 
•
announcements of new products, technologies, commercial relationships, acquisitions, collaborations or other 
events by us or our competitors;
•
the success or failure of our therapies;
•
other developments with respect to our pipeline, including initiation of clinical trials of existing products in 
additional indications or key decisions of the FDA;
•
regulatory or legal developments in the U.S. and other countries;
•
adverse developments with respect to our intellectual property portfolio or failure to obtain or loss of 
exclusivity;
•
failure of our future product candidates, if successfully developed and approved, to achieve commercial 
success;
•
fluctuations in stock market prices and trading volumes of similar companies;
•
the state of the U.S. and world economies, general market conditions and overall fluctuations in U.S. equity 
markets, including as a result of U.S. or world events;
•
changes in healthcare laws affecting pricing, reimbursement or access;
•
variations in our quarterly operating results, including as a result of events beyond our control, such as natural 
disasters, regional economic downturns, pandemics or other global health crises, social unrest, political 
instability, terrorism, or acts of war;
•
changes in our financial guidance or securities analysts’ estimates of our financial performance;
•
changes in accounting principles;
•
our ability to raise additional capital and the terms on which we can raise it;
•
the impact of macroeconomic and geopolitical conditions;
•
sales of large blocks of our common stock, including sales by our executive officers, directors and significant 
stockholders;
•
additions or departures of key personnel;
•
discussion of us or our stock price by the press and by online investor communities; and
•
other risks and uncertainties described in these risk factors.

88
We are currently subject to legal actions and proceedings, which could distract our management and could result in 
substantial costs or large judgments against us.
In August 2024, a plaintiff filed a purported federal securities class action lawsuit in the Southern District of New 
York, or the Securities Class Action, against us and certain of our executive officers alleging violations of U.S. securities 
laws under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder and 
seeking an as-yet unspecified amount of damages allegedly sustained by parties who purchased our stock between April 
12, 2021 and July 23, 2024, as well as applicable attorneys’ fees and costs. In addition, we received a subpoena from the 
Enforcement Division of the U.S. Securities and Exchange Commission, or the SEC, in October 2024, requesting 
documents and information related to our NDA for zuranolone for the treatment of MDD, including communications with 
the FDA and any communications containing material nonpublic information. 
At this time, we are unable to predict the outcome of the Securities Class Action or the SEC investigation or 
reasonably estimate a range of possible losses. If either of these matters were concluded in a manner adverse to us and for 
which we incur substantial costs or damages not covered by our directors’ and officers’ liability insurance, such a 
conclusion could have a material adverse effect on our financial condition and business. In addition, either of these 
matters could adversely impact our reputation and divert management’s attention and resources from other priorities, 
including the execution of business plans and strategies that are important to our ability to grow our business, any of 
which could have a material adverse effect on our business.
We have broad discretion in how we use our existing cash and the proceeds from potential future follow-on public 
offerings, and may not use such cash and proceeds effectively, which could affect our results of operations and cause 
our stock price to decline.
We have considerable discretion in the use of our cash and the application of the net proceeds from potential future 
follow-on public offerings. We may use cash and net proceeds for purposes that do not yield a significant return or any 
return at all for our stockholders. In addition, pending their use, we may invest the net proceeds from any potential future 
follow-on offerings in a manner that does not produce income or that loses value.
Anti-takeover provisions in our charter documents and under Delaware law could make an acquisition of us, even one 
that 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 amended and restated bylaws may delay or 
prevent an acquisition of us or a change in our management. These provisions include a classified board of directors, a 
prohibition on actions by written consent of our stockholders and the ability of our board of directors to issue preferred 
stock without stockholder approval. In addition, because we are incorporated in Delaware, we are governed by the 
provisions of Section 203 of the Delaware General Corporation Law, which limits the ability of stockholders owning in 
excess of 15% of our outstanding voting stock to merge or combine with us. Although we believe these provisions 
collectively provide for an opportunity to obtain greater value for stockholders by requiring potential acquirers to 
negotiate with our board of directors, they would apply even if an offer rejected by our board were considered beneficial 
by some 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.
Future sales of our common stock may cause our stock price to decline.
Sales of a substantial number of shares of our common stock in the public market or the perception that these sales 
might occur could significantly reduce the market price of our common stock, and impair our ability to raise adequate 
capital through the sale of additional equity securities. For example, the 6,241,473 shares of our common stock purchased 
by BIMA are no longer subject to contractually-agreed lockup periods and volume limitations, the last of which expired 
on December 31, 2023, and accordingly, BIMA is able to sell these shares without contractual limitations.

Item 1B. Unresolved Staff Comments
None.
Item 1C. Cybersecurity
Risk Management and Strategy
As is the case for similar companies of our size and industry, we may be the target of cyber attacks and other cyber 
incidents and, therefore, cybersecurity is an important element of our overall enterprise risk management program. We 
have certain processes to systematically evaluate, identify, address, and manage cybersecurity risks, which are built into 
our overall risk management program and are designed to help safeguard our information assets and operational integrity 
from internal and external cyber threats, protect employee information from unauthorized access or attack, as well as 
secure our networks and systems. Such processes include physical, procedural, and technical safeguards, response plans, 
and continuity exercises on our systems. We also routinely review our policies and procedures to identify risks and refine 
our practices. By prioritizing cyber risk comprehension and management, we aim to enhance business resiliency, protect 
information from unauthorized access or attacks, and secure our digital footprint.
We engage certain external parties, including cybersecurity and privacy firms, to enhance our cybersecurity 
oversight and risk reduction abilities. We also perform an annual cybersecurity assessment designed to help align our 
cybersecurity program with industry best practices. In addition, we regularly consult with industry groups, peer 
organizations, and external executives to assess the cybersecurity threat landscape throughout the year.
Our cybersecurity policies, standards, and procedures include cyber and data breach response plans benchmarked 
against multiple cybersecurity risk frameworks. Our incident response plan is designed to help coordinate the response to 
and recovery from cybersecurity incidents and includes processes to identify, investigate, triage, assess the severity of, 
escalate, contain, and remediate incidents and comply with applicable legal or regulatory obligations. We also regularly 
perform technical reviews of our systems to help secure our digital environment and confirm software patches are 
appropriately up-to-date.
To oversee and identify risks from cybersecurity threats associated with our use of third-party service providers, we 
have implemented a third-party risk management program designed to help protect against information misuse and assess 
the information technology security measures of potential third parties and business partners. We perform a third-party 
risk assessment before starting a relationship with certain service providers and utilize a third-party risk intelligence 
program to monitor the activity of critical vendors following engagement. In addition, we maintain cyber insurance 
coverage as part of our overall risk mitigation strategy. This cyber insurance coverage may not be sufficient to cover 
against all claims.
We do not believe that there are currently any risks from cybersecurity threats that are reasonably likely to 
materially affect us or our business strategy, results of operations or financial condition.
Governance
Our Audit Committee of the Board of Directors provides direct oversight over cybersecurity risk. The Audit 
Committee receives annual updates from management regarding cybersecurity matters and is notified between such 
updates regarding significant new cybersecurity threats or incidents, if applicable. 
We also have a cybersecurity steering committee responsible for assisting with our overall day-to-day cybersecurity 
responsibilities and implementing our cybersecurity programs. The cybersecurity steering committee is currently 
comprised of members of our digital and enterprise capabilities team and is chaired by our executive director of 
cybersecurity. Among other things, the cybersecurity steering committee:
•
reviews our internal controls to help protect our information assets;
•
assists with developing practices, procedures, and controls designed to identify, assess, and manage critical 
cybersecurity programs and risks; and 
•
works to align our risk governance structure, including policies and procedures, with our business objectives.

90
The chair of the cybersecurity steering committee, our executive director of cybersecurity, has over 25 years of 
information technology industry experience, including 20 years focused on cybersecurity, and master’s degrees in a 
cybersecurity discipline and in business administration, in addition to multiple certifications related to information 
technology and cybersecurity. 
In addition, to help prevent and detect cybersecurity threats, we provide all employees, including part-time and 
temporary employees, with monthly cybersecurity and privacy training, which covers timely and relevant cybersecurity 
topics, including social engineering, phishing, password protection, confidential data protection, asset use, and mobile 
security.
Item 2. Properties
Our corporate headquarters are located in Cambridge, Massachusetts. We lease 30,567 square feet of office space in 
a multi-tenant building pursuant to a lease dated as of January 2024, that will expire on February 28, 2030.
We have entered into other non-material leases and may lease additional space prior to the expiration of our leases to 
meet the needs of the business. 
Item 3. Legal Proceedings 
On August 28, 2024, named plaintiff Darren Korver filed a purported federal securities class action lawsuit in the 
Southern District of New York against us and individuals, Barry E. Greene and Kimi Iguchi, or the Securities Class 
Action. The complaint in the Securities Class Action alleges violations of U.S. securities laws under Sections 10(b) and 
20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder and seeks an as-yet unspecified 
amount of damages allegedly sustained by parties who purchased Sage stock between April 12, 2021 and July 23, 2024, 
as well as applicable attorneys’ fees and costs. We deny any allegations of wrongdoing and intend to vigorously defend 
against the Securities Class Action. 
On October 16, 2024, we received a subpoena from the Enforcement Division of the U.S. Securities and Exchange 
Commission, or the SEC, requesting documents and information related to our new drug application for zuranolone for 
the treatment of MDD, including communications with the FDA and any communications containing material nonpublic 
information. We are cooperating with the SEC and intend to continue to provide information responsive to the SEC’s 
requests. 
At this time, we are unable to predict the outcome of the Securities Class Action or the SEC investigation or 
reasonably estimate a range of possible losses.
On January 16, 2025, we commenced litigation against Biogen Inc. and Biogen MA Inc., or together with Biogen 
Inc., Biogen, in the Delaware Court of Chancery seeking declaratory, injunctive and other relief.  The action is captioned 
Sage Therapeutics, Inc. v. Biogen Inc., et al., C.A. No. 2025-0054-BWD (Del. Ch.).  In our complaint, we allege that 
Biogen breached the standstill provision in the stock purchase agreement we entered into with Biogen on November 27, 
2020, or the Biogen Stock Purchase Agreement, by making an unsolicited acquisition proposal and related public 
disclosures. On this basis, we also sought a temporary restraining order enjoining Biogen from future breaches of the 
standstill provision. At a hearing held on January 28, 2025, the Court granted our motion for a temporary restraining order 
against Biogen MA Inc., and entered an implementing order on January 30, 2025, or the TRO Order.  Pursuant to the 
TRO Order, unless consented to by Sage in writing or otherwise ordered by the court, Biogen MA Inc. and its directors, 
officers, agents, employees, attorneys, representatives, persons in active concert or participation with it, and anyone acting 
under its direction or control are enjoined from taking any action inconsistent with the Biogen Stock Purchase 
Agreement’s contractual prohibitions against (i) making a public acquisition proposal, (ii) making a private acquisition 
proposal that is reasonably expected to require public disclosure, or (iii) publicly encouraging any acquisition proposal. 
Various motions and related items (whether procedural, discovery-related and/or substantive in nature) occur from time to 
time with respect to this matter.  We intend to continue to vigorously pursue our claims against Biogen, but we are unable 
to predict the outcome of the litigation at this time.

91
We may from time to time become involved in other legal proceedings relating to claims arising from our ordinary 
course of business, including claims related to contracts, employment arrangements, operating activities, intellectual 
property or other matters. 
Item 4. Mine Safety Disclosures

Information pertaining to fiscal year 2022 was included in the Company’s Annual Report on Form 10-K for the 
year-ended December 31, 2023, on pages 92 through 113, under Part II, Item 7, “Management’s Discussion and Analysis 
of Financial Condition and Results of Operations,” which was filed with the SEC on February 14, 2024.
Overview
We are a biopharmaceutical company with a mission to pioneer solutions to deliver life-changing brain health 
medicines, so every person can thrive. Alongside our commercial product for the treatment of postpartum depression, we 
are advancing a portfolio of internally discovered novel chemical entities with the potential to become differentiated 
treatments designed to improve brain health by primarily targeting two critical central nervous system, or CNS, receptor 
systems, GABA and NMDA. The GABA receptor family, which is recognized as the major inhibitory neurotransmitter in 
the CNS, mediates downstream neurologic and bodily function via activation of GABAA receptors. The NMDA-type 
receptors of the glutamate receptor system are a major excitatory receptor system in the CNS. Dysfunction in these 
systems is thought to be at the core of numerous neuropsychiatric and neurodevelopmental disorders. 
Our product ZURZUVAE® (zuranolone) was approved by the U.S. Food and Drug Administration, or FDA, on 
August 4, 2023 for the treatment of postpartum depression, or PPD, in adults. ZURZUVAE is a neuroactive steroid that is 
a positive allosteric modulator of GABAA receptors, targeting both synaptic and extrasynaptic GABAA receptors, and is 
the first oral, once-daily, 14-day treatment specifically indicated for adults with PPD. ZURZUVAE became commercially 
available in the U.S. in December 2023 as a treatment option for women with PPD. We and our collaboration partner, 
Biogen MA Inc., or BIMA, and Biogen International GmbH, or, together with BIMA, Biogen, are jointly commercializing 
ZURZUVAE in the U.S. under our collaboration and license agreement, or the Biogen Collaboration Agreement, that 
became effective in December 2020. We and Biogen equally share in all operating profits and losses arising from sales of 
ZURZUVAE in the U.S., with Biogen recording such product sales. 
We jointly commercialize ZURZUVAE with Biogen in the U.S. and have the right to jointly commercialize any 
additional products containing zuranolone, which, along with ZURZUVAE, we refer to as Licensed 217 Products, if our 
ongoing and any future development efforts are successful. In addition, we have granted Biogen sole rights to develop and 
commercialize the Licensed 217 Products outside the U.S., other than in Japan, Taiwan and South Korea, or the Shionogi 
Territory, with respect to zuranolone, where we have granted such rights to Shionogi & Co., Ltd., or Shionogi. We refer to 
the territories outside the U.S. to which Biogen has rights under the Biogen Collaboration Agreement with respect to the 
Licensed 217 Products as the Biogen Territory.

95
We also have a collaboration agreement with Shionogi for the development of zuranolone in the Shionogi Territory. 
Shionogi is currently developing zuranolone for the treatment of major depressive disorder, or MDD, in Japan. In the third 
quarter of 2024, Shionogi reported that it submitted a new drug application, or NDA, in Japan for zuranolone for the 
treatment of MDD.
Under the Biogen Collaboration Agreement, we and Biogen also previously agreed to jointly develop and 
commercialize products containing SAGE-324, which we refer to as the Licensed 324 Products. 
Following announcement of topline results from the KINETIC 2 Phase 2b clinical trial, which failed to meet its 
primary endpoint, in September 2024, Biogen notified us of its termination of the Biogen Collaboration Agreement solely 
with respect to the Licensed 324 Products on a worldwide basis, effective February 17, 2025, or the SAGE-324 
Termination. As a result of the SAGE-324 Termination, as of February 17, 2025, all licenses granted by us to Biogen or 
by Biogen to us regarding the Licensed 324 Products shall expire with respect to the Licensed 324 Products on a 
worldwide basis. Biogen shall grant to us an irrevocable, perpetual license for any Biogen background technology, Biogen 
collaboration technology or joint collaboration technology that exists as of February 17, 2025 with respect to the Licensed 
324 Products on a worldwide basis, in each case in accordance with the terms of the Biogen Collaboration Agreement. We 
and Biogen continue to be responsible for our respective share of costs for ongoing activities related to the Licensed 324 
Products in accordance with the terms of the Biogen Collaboration Agreement until February 17, 2025. 
We are evaluating other potential indications for SAGE-324, including seizures in developmental and epileptic 
encephalopathies, or DEEs, and expect to provide an update on next steps, if any, in mid-2025.
Our other area of focus is SAGE-319, an extrasynaptic-preferring GABAA receptor positive allosteric modulator, or 
GABAA PAM, designed to have a novel pharmacology and a differentiated clinical profile from other GABAA PAMs in 
our portfolio. We are currently investigating SAGE-319 as a potential treatment for behavioral symptoms associated with 
certain neurodevelopmental disorders. We expect to announce data from a Phase 1 multiple ascending dose study of 
SAGE-319 for behavioral symptoms associated with certain neurodevelopmental disorders by late 2025, and will evaluate 
next steps, if any, based on these data.
We previously commercialized ZULRESSO® (brexanolone) CIV injection for the treatment of PPD. ZULRESSO is 
approved in the U.S. for the treatment of PPD in individuals 15 years old and older. ZULRESSO was administered as a 
continuous intravenous infusion for two and a half days and could only be administered in qualified medically-supervised 
healthcare settings. Given the complexities and challenges associated with administration of ZULRESSO, use of the 
product was limited and further reduced as a result of the availability of ZURZUVAE for the treatment of women with 
PPD. For that reason, we discontinued commercial availability of ZULRESSO in the U.S. as of December 31, 2024.
Additionally, we previously evaluated dalzanemdor in certain cognitive disorders associated with NMDA receptor 
dysfunction. In November 2024, based on the results of our Phase 2 DIMENSION, LIGHTWAVE, and PRECEDENT 
Studies, which failed to meet their primary endpoints, we announced that we do not plan to pursue any further 
development of dalzanemdor.
We expect to continue to focus on the development of product candidates for the treatment of both acute and chronic 
brain health disorders, including work on allosteric modulation of the GABAA and NMDA receptor systems in the brain, 
and are continuing to explore targeted work within our NMDA receptor negative allosteric modulator, or NMDAR 
NAMs, platform with SAGE-817 and SAGE-039. The GABAA and NMDA receptor systems are broadly accepted as 
impacting many neuropsychiatric and neurodevelopmental disorders, spanning disorders of mood, seizure, cognition, 
anxiety, sleep, pain, and movement, among others. We believe that we may have the opportunity to develop molecules 
from our internal portfolio with the goal of addressing a number of these disorders in the future, and also believe that we 
may have opportunity to use our scientific approach to explore targets beyond the GABAA and NMDA receptor systems 
and to develop compounds in areas of unmet need outside of brain health.
On January 10, 2025, we received an unsolicited, non-binding acquisition proposal from Biogen to acquire all of our 
outstanding shares not owned by Biogen for $7.22 per share, or the Biogen Proposal. On January 27, 2025, we announced 
that our Board of Directors has initiated a process to explore strategic alternatives, and further announced that our Board 
of Directors unanimously rejected the Biogen Proposal. On January 16, 2025, we commenced litigation against Biogen in 
the Delaware Court of Chancery seeking to enforce the standstill provision in the stock purchase agreement we entered 
into with Biogen on November 27, 2020. Our rejection of the Biogen Proposal, our efforts to enforce the terms of the 

96
stock purchase agreement and our strategic review process may adversely impact our relationship with Biogen, including 
our efforts to commercialize ZURZUVAE for the treatment of women with PPD. We cannot be certain that our efforts to 
date with Biogen, including regarding sales force coordination, engagement with payors, and education efforts related to 
PPD, will not be adversely impacted or that Biogen will continue to make investments related to ZURZUVAE. Any 
disruption of our relationship with Biogen under our collaboration agreement with Biogen may have an adverse impact on 
sales of ZURZUVAE, which could in turn materially adversely affect our business, results of operations, financial 
condition and prospects. We have not set a timetable for the strategic review process, nor have we made any decisions 
related to any potential strategic alternatives at this time. There can be no assurance that our strategic review process will 
result in any transaction or other strategic outcome. We do not intend to disclose further developments on this strategic 
review process unless and until we determine that such disclosure is appropriate or necessary. If we determine to engage 
in a transaction as a result of our exploration and evaluation of strategic alternatives, our future business, prospects, 
financial position and operating results could be significantly different than those in historical periods or projected by our 
management. 
We began to generate revenue from product sales in the second quarter of 2019 in conjunction with the launch of our 
product ZULRESSO in June 2019. In the fourth quarter of 2020, we recorded revenue from the strategic collaboration 
with and stock purchase by Biogen. In addition, we record as “collaboration revenue - related party” our share of Biogen’s 
sales of ZURZUVAE, which became commercially available in December 2023. We also achieved and recognized a 
milestone totaling $75.0 million for the first commercial sale of ZURZUVAE for the treatment of women with PPD in the 
U.S. in the fourth quarter of 2023, as a result of the first sale of ZURZUVAE to a distributor, and received the milestone 
payment in January 2024.
We have incurred net losses in each year since our inception, except for net income of $606.1 million for the year 
ended December 31, 2020, reflecting revenue recognized under the Biogen Collaboration Agreement, and we had an 
accumulated deficit of $3.0 billion as of December 31, 2024. Our net losses were $400.7 million, $541.5 million, and 
$532.8 million for the years ended December 31, 2024, 2023 and 2022, respectively. These losses have resulted 
principally from costs incurred in connection with research and development activities and selling, general and 
administrative costs associated with our operations and expansion of our commercial operations. We expect to incur 
significant expenses and continued operating losses for the foreseeable future.
In October 2024, we implemented a strategic reorganization of our business operations intended to strengthen our 
balance sheet and focus investment on the ongoing launch of ZURZUVAE for the treatment of women with PPD and our 
prioritized pipeline development efforts, or the 2024 Restructuring. As part of the 2024 Restructuring, we implemented a 
reduction of approximately 33% of our total workforce and approximately 55% of our research and development 
workforce. We anticipate that the implementation of the 2024 Restructuring and our pipeline prioritization will result in a 
reduction of our operating expenses in 2025 relative to 2024. Based upon our current operating plan, we anticipate that 
our existing cash, cash equivalents and marketable securities as of December 31, 2024, together with anticipated funding 
from our ongoing collaborations and estimated revenues, excluding any potential milestone payments we may receive 
under our collaboration agreements, will support our operations to mid-2027. We have based this estimate on assumptions 
that may prove to be wrong, such as the revenue that we expect to realize from our collaboration agreement for the 
continued commercialization of ZURZUVAE for the treatment of women with PPD. To the extent estimated revenue 
levels are not realized, we may adjust our operating plan accordingly, including the deferral or reduction of planned 
operating expenses, as needed. See “—Liquidity and Capital Resources”.
Although we expect that our operating expenses will decrease in 2025 as compared to 2024 as a result of our 
pipeline prioritization and the anticipated cost savings from the 2024 Restructuring, we expect to continue to incur 
significant costs in connection with our ongoing activities, including if and as we pursue key elements of our strategy to:
•
successfully commercialize ZURZUVAE, along with our collaboration partner, Biogen, for the treatment of 
women with PPD in the U.S., including our goals to establish ZURZUVAE as the standard of care for women 
with PPD, expand market growth in PPD, accelerate topline revenue growth, and ultimately help more women 
with PPD; 
•
investigate SAGE-319 as a potential treatment for behavioral symptoms associated with certain 
neurodevelopmental disorders;

97
•
evaluate potential further indications for SAGE-324;
•
support our collaboration with Biogen with respect to zuranolone in the U.S., and support Biogen’s 
development of zuranolone in the Biogen Territory and Shionogi’s development of zuranolone in the Shionogi 
Territory;
•
continue work on our prioritized pipeline focused on neurodevelopmental disorders and neuropsychiatry, 
including to explore targeted work within our NMDAR NAMs platform with SAGE-817 and SAGE-039;
•
focus on maintaining a strong balance sheet while reducing operating expenses;
•
continue to explore business development opportunities, including opportunities to establish licenses, 
collaborations, or other agreements or alliances with other biotechnology and pharmaceutical companies, at the 
appropriate time, where we believe a collaboration may add significant value to our efforts, including through 
capabilities, infrastructure, speed or financial contributions, or to acquire new compounds, product candidates 
or products if we believe such opportunities will help us achieve our goals or meet other strategic objectives;
•
prepare and file NDAs with the FDA, and conduct permitted pre-launch activities with respect to any of our 
product candidates that we believe have been successfully developed;
•
commercialize any product candidates for which we obtain regulatory approval, including the manufacture of 
commercial supplies;
•
evaluate the market potential and regulatory pathways for our product candidates beyond zuranolone in the 
European Union, or EU, and other jurisdictions outside the U.S., and determine how best to move forward 
where and when it may make business and strategic sense; and
•
continue to build, maintain, defend, leverage, and expand our intellectual property portfolio, including by 
utilizing the strengths of our proprietary chemistry platform and scientific know-how to expand our portfolio of 
new chemical entities with the goals of lessening our long-term reliance on the success of any one program and 
facilitating long-term growth.
Until such time that we can generate significant revenue on a sustained basis from product sales and/or from 
collaborations, if ever, we expect to finance our operations primarily through a combination of revenue, equity or debt 
financings and other sources of financing, including our collaborations with Biogen and Shionogi and potential future 
collaborations. We may not be successful in our ongoing commercialization of ZURZUVAE or any other product and 
may not generate meaningful revenue or revenue at the levels or on the timing necessary to support our investment and 
goals. We may never successfully complete development of any of our current or future product candidates, successfully 
file for or obtain necessary regulatory approval for such product candidates or achieve commercial viability for any 
resulting approved product. We may not obtain or maintain adequate patent protection or other exclusivity for our 
products or product candidates. Adequate additional financing may not be available to us on acceptable terms, or at all. 
Our inability to raise capital if and when needed would have a negative impact on our financial condition and on our 
ability to pursue our business strategy. Arrangements with our existing collaborators have required us to relinquish rights 
to certain of our technologies or product candidates, and any future collaborations, licenses, or similar arrangements may 
require us to relinquish additional rights. We will need to generate significant revenue to achieve profitability, and we 
may never do so.
Financial Operations Overview
Revenue
We began to generate revenue from product sales in the second quarter of 2019 in conjunction with the launch of our 
product ZULRESSO as a treatment for PPD. In addition, in late 2023, we began to generate collaboration revenue - 
related party from our share of Biogen’s sales of ZURZUVAE in the U.S.
ZURZUVAE became commercially available in the U.S. in December 2023 as the first and only oral product 
approved by the FDA specifically for the treatment of adults with PPD. We and Biogen are jointly commercializing 
ZURZUVAE in the U.S. for the treatment of women with PPD under the Biogen Collaboration Agreement. We and 

98
Biogen equally share in all operating profits and losses arising from sales of ZURZUVAE in the U.S., with Biogen 
recording such product sales.
We and Biogen are utilizing a specialty pharmacy distribution model by which ZURZUVAE is shipped directly to 
women with PPD who are prescribed the treatment. We and Biogen have active field sales forces supported by 
experienced sales leadership teams and professionals in marketing, access and reimbursement, managed markets, market 
research, commercial operations, and sales force planning and management. We and Biogen are continuing to engage in 
discussions with national, regional and government payors to advocate for broad and equitable access to ZURZUVAE for 
women with PPD with minimal restrictions. Payor coverage for ZURZUVAE for the treatment of women with PPD is 
currently in place for a majority of commercial and Medicaid covered lives without step therapy or complex prior 
authorizations, including coverage from all three national Pharmacy Benefit Managers. We expect formulary discussions 
to continue over the course of 2025.
In the fourth quarter ending December 31, 2024, nearly 2,500 prescriptions for ZURZUVAE were shipped and 
delivered to women with PPD, an approximately 21% increase from the prior quarter. For the year ended December 31, 
2024, the first full year of shipments, more than 6,600 prescriptions were shipped and delivered. To help enable broad and 
equitable access, we also maintain a patient support program, ZURZUVAE For You, which provides educational 
resources, help with understanding insurance coverage, and assistance navigating the prescription fulfillment process for 
women with PPD who are prescribed treatment. This program also includes financial assistance for women with PPD, 
such as the potential for copay assistance for those with commercial insurance and the potential to be provided product at 
no cost for other eligible patients
We will not generate revenue from other products unless and until we or any of our collaborators successfully 
develop, obtain regulatory approval of, and commercialize one of our current or future product candidates. If we enter into 
additional collaboration agreements with third parties for our product candidates, we may generate revenue from those 
collaborations. We expect that revenue, if any, that we may generate under our existing or future collaboration agreements 
will fluctuate from quarter to quarter as a result of the timing and amount of license fees, payments for clinical materials 
or manufacturing services, milestone payments, royalties paid to us and our share of collaboration revenues resulting from 
sales of any commercialized products, and other payments.
In June 2018, we entered into a strategic collaboration with Shionogi for the clinical development and 
commercialization of zuranolone for the treatment of MDD and other potential indications in the Shionogi Territory. 
Under the terms of the agreement, Shionogi is responsible for all clinical development, regulatory filings and 
commercialization and drug product manufacturing of zuranolone for the treatment of MDD, and potentially other 
indications, in the Shionogi Territory. In October 2018, we also entered into a clinical supply agreement with Shionogi 
under which we supply Shionogi with zuranolone material for clinical and development purposes. To date, revenue from 
our collaboration with Shionogi has come from an initial, upfront license fee upon execution of the collaboration 
agreement of $90.0 million in the year ended December 31, 2018, and from the supply of materials under the clinical 
supply agreement. In the third quarter of 2024, Shionogi announced that it had submitted an NDA in Japan for zuranolone 
for the treatment of MDD.
In November 2020, we entered into the Biogen Collaboration Agreement with Biogen for the development, 
manufacture and commercialization of the Licensed 217 Products and the Licensed 324 Products. In connection with the 
execution of the Biogen Collaboration Agreement, we also entered into a stock purchase agreement for the sale and 
issuance to BIMA of 6,241,473 shares of our common stock for aggregate consideration of $650.0 million. The Biogen 
Collaboration Agreement became effective in December 2020, and the sale of the common stock under the stock purchase 
agreement closed on December 31, 2020. In September 2024, Biogen notified us of the SAGE-324 Termination.
Under the terms of the Biogen Collaboration Agreement, we will jointly develop and, if successful, jointly 
commercialize the Licensed 217 Products in the U.S. and Biogen solely will develop and commercialize the Licensed 217 
Products in the Biogen Territory. We and Biogen have agreed to share equally all costs for activities, as well as the profits 
and losses, upon FDA approval of the Licensed 217 Products solely for the U.S. Under the Biogen Collaboration 
Agreement, Biogen is solely responsible for all costs for activities in the Biogen Territory. Biogen is the principal and 
records sales of ZURZUVAE in the U.S. and will be the principal and record sales of Licensed 217 Products globally. 
In the year ended December 31, 2020, we recorded license and milestone revenue – related party of $1.1 billion, 
consisting of an upfront payment of $875.0 million plus $232.5 million in excess proceeds from the equity investment 

99
under the stock purchase agreement, when measured at fair value. We also achieved a milestone under the Biogen 
Collaboration Agreement totaling $75.0 million and recorded license and milestone revenue - related party in the fourth 
quarter of 2023 for the first commercial sale of ZURZUVAE for the treatment of women with PPD in the U.S., as a result 
of the first sale of ZURZUVAE to a distributor, and received the milestone payment in January 2024. As a result of the 
SAGE-324 Termination, we will not receive any milestone payments for Licensed 324 Products under the Biogen 
Collaboration Agreement. For further discussion regarding the accounting for the Biogen Collaboration Agreement, refer 
to Note 7, Collaboration Agreements, in the accompanying Notes to Consolidated Financial Statements appearing 
elsewhere in this Annual Report.
Collaborative Arrangements
We analyze our collaboration arrangements to assess whether such arrangements involve joint operating activities 
performed by parties that are both active participants in the activities and exposed to significant risks and rewards 
dependent on the commercial success of such activities and therefore within the scope of Accounting Standards 
Codification, or ASC, Topic 808, Collaborative Arrangements, or Topic 808. This assessment is performed throughout 
the life of the arrangement based on changes in the responsibilities of all parties in the arrangement. For collaboration 
arrangements within the scope of Topic 808 that contain multiple elements, we first determine which elements of the 
collaboration are deemed to be within the scope of Topic 808 and which elements of the collaboration are more reflective 
of a vendor-customer relationship and therefore within the scope of ASC Topic 606, Revenue from Contracts with 
Customers, or Topic 606. For elements of collaboration arrangements that are accounted for pursuant to Topic 808, an 
appropriate recognition method is determined and applied consistently, either by analogy to authoritative accounting 
literature or by applying a reasonable and rational policy election. For those elements of the arrangement that are 
accounted for pursuant to Topic 606, we apply the five-step revenue recognition model and present the arrangement as 
license and milestone revenue or other collaboration revenue in the consolidated statements of operations and 
comprehensive loss.
For collaboration arrangements that are within the scope of Topic 808, we evaluate the income statement 
classification for presentation of amounts due from or owed to other participants associated with multiple activities in a 
collaboration arrangement based on the nature of each separate activity. Payments or reimbursements that are the result of 
a collaborative relationship, instead of a customer relationship, are recorded as an increase to collaboration revenue, an 
increase to or reduction of cost of revenues, research and development expense or selling, general and administrative 
expense, depending on the nature of the activity. For further discussion regarding the accounting for collaborative 
arrangements, refer to Note 7, Collaboration Agreements, in the accompanying Notes to Consolidated Financial 
Statements appearing elsewhere in this Annual Report.
We expect that revenue, if any, that we may generate under our collaboration agreements will fluctuate from quarter 
to quarter as a result of the timing and amount of license fees, payments for clinical materials or manufacturing services, 
milestone payments, royalties paid to us and our share of collaboration revenues from sales of any commercialized 
products, and other payments. We expect that our collaboration revenue will increase due to the commercial launch of 
ZURZUVAE for the treatment of women with PPD that commenced in December 2023. For further discussion regarding 
our collaboration agreements with Shionogi and Biogen and the accounting for revenue from collaboration agreements, 
refer to Note 2, Summary of Significant Accounting Policies and Note 7, Collaboration Agreements, in the accompanying 
Notes to Consolidated Financial Statements appearing elsewhere in this Annual Report.
Cost of Revenues
Cost of revenues included direct and indirect costs related to the manufacturing and distribution of ZULRESSO, 
including third-party manufacturing costs, packaging services, freight, third-party royalties payable on our net product 
revenue of ZULRESSO and amortization of intangible assets associated with ZULRESSO. Cost of revenues also includes 
our proportionate share of ZURZUVAE manufacturing costs under the Biogen Collaboration Agreement, (for further 
discussion regarding our collaboration agreement with Biogen and the accounting from collaboration agreements, refer to 
Note 2, Summary of Significant Accounting Policies and Note 7, Collaboration Agreements, in the accompanying Notes to 
Consolidated Financial Statements appearing in Part IV, Item 15 of this Annual Report). Cost of revenues may also 
include period costs, related to certain inventory manufacturing services and inventory adjustment charges. We expect to 

100
utilize zero-cost inventory for ZURZUVAE for an extended period of time. We expect that our overall cost of revenues 
will increase over time due to sales of ZURZUVAE and the recording of our proportionate share of product costs in the 
U.S. under the Biogen Collaboration Agreement.
Operating Expenses
Our operating expenses consist primarily of costs associated with research and development activities and selling, 
general and administrative activities.
Research and Development Expenses
Research and development expenses, which consist primarily of costs associated with our product research and 
development efforts, are expensed as incurred. Research and development expenses consist primarily of:
•
personnel costs, including salaries, benefits, stock-based compensation and travel expenses, for employees 
engaged in research and development functions;
•
expenses incurred under agreements with contract research organizations, or CROs, and sites that conduct our 
non-clinical studies and clinical trials;
•
expenses associated with manufacturing materials for use in non-clinical studies and clinical trials and 
developing external manufacturing capabilities;
•
costs of outside consultants engaged in research and development activities, including their fees and travel 
expenses;
•
other expenses related to our non-clinical studies and clinical trials and expenses related to our regulatory 
activities;
•
payments made under our third-party license agreements; and
•
a portion of our information technology, facilities and other related expenses, including rent, depreciation, 
maintenance of facilities, insurance and supplies.
We consider the collaborative activities associated with the co-development, co-commercialization, and co-
manufacturing of the Licensed 217 Products and, through the SAGE-324 Termination effective date, the Licensed 324 
Products in the U.S. to be separate units of account within the scope of Topic 808 as we and Biogen are both active 
participants in the development and commercialization activities and are exposed to significant risks and rewards that are 
dependent on the development and commercial success of the activities in the arrangement. In periods prior to 
commercialization, payments to or reimbursements from Biogen related to the co-development and co-manufacturing 
activities are accounted for as an increase to or reduction of research and development expense. Following 
commercialization in the U.S., payments to or reimbursements from Biogen related to commercial co-manufacturing 
activities in the U.S. are accounted for as an increase to or reduction of cost of revenues. During the years ended 
December 31, 2024, 2023, and 2022, we recorded net reimbursement of $15.7 million, $76.2 million, and $73.2 million, 
respectively, from Biogen that was deducted from our research and development expenses because we incurred a greater 
amount of these expenses than Biogen.
Costs for certain development activities are recognized based on an evaluation of the progress to completion of 
specific tasks using information and data provided to us by our vendors and our clinical sites.

101
We have been developing our product candidates and focusing on other research and development programs, 
including exploratory efforts to identify new compounds, target validation for identified compounds and lead optimization 
for our earlier-validated programs. Our direct research and development expenses are tracked on a program-by-program 
basis, and consist primarily of external costs, such as fees paid to investigators, central laboratories, CROs and contract 
manufacturing organizations in connection with our non-clinical studies and clinical trials; third-party license fees related 
to our product candidates; and fees paid to outside consultants who perform work on our programs. We do not allocate 
employee-related costs and other indirect costs to specific research and development programs because these costs are 
deployed across multiple product programs under research and development and, as such, are separately classified as 
unallocated or stock-based compensation in research and development expenses.
Research and development activities are central to our business. Even though we have post-approval obligations for 
ZURZUVAE, we expect that our research and development spending will decrease as a result of the reprioritization of our 
pipeline development efforts and the anticipated cost savings from the 2024 Restructuring. 
We cannot determine with certainty the duration and costs of the current or future clinical trials of our product 
candidates. The duration, costs, and timing of clinical trials and development of our product candidates will depend on a 
variety of factors, including:
•
the scope, size, rate of progress, and expense of our ongoing as well as any additional clinical trials, non-
clinical studies, and other research and development activities;
•
future results of ongoing, planned or future clinical trials and non-clinical studies;
•
decisions by regulatory authorities related to our product candidates;
•
uncertainties in clinical trial enrollment rate or design;
•
significant and changing government regulation; and 
•
the receipt and timing of regulatory approvals, if any.
In addition, healthcare and vendor staffing shortages and disruption to the U.S. healthcare system, and/or the impact 
of other macroeconomic and geopolitical conditions, may also negatively impact our ongoing and planned development 
activities and increase our research and development costs. Concerns, precautions and restrictions related to future 
pandemics or other events, staffing shortages, or other changes to the macroeconomic environment may substantially slow 
clinical site identification and activation and enrollment in our clinical trials, may impair or delay the conduct, auditing, 
monitoring, or completion of our trials, may impair or impede the timeliness and completion of our data collection and 
analysis efforts or the integrity of our data, or may cause us to pause trials, in each case which may significantly impact 
our ability to meet our expected timelines or cause us to change our plans and may significantly increase our research and 
development costs. 
A change in the outcome of any of these variables with respect to the development of a product candidate could 
mean a significant change in the costs and timing associated with the development of that product candidate. For example, 
if the FDA or another regulatory authority were to require us to conduct clinical trials beyond those that we currently 
anticipate will be required for the completion of clinical development of a product candidate or for regulatory approval, or 
if we experience significant delays in enrollment in any of our clinical trials or need to enroll additional patients, we could 
be required to expend significant additional financial resources and time on the completion of clinical development.
Any failure to complete any stage of the development of any potential product candidates in a timely manner could 
have a material adverse effect on our operations, financial position and liquidity. A discussion of some of the risks and 
uncertainties associated with not completing our programs on schedule, or at all, and the potential consequences of failing 
to do so, are set forth in Part I, Item 1A of this Annual Report under the heading “Risk Factors”.

102
Selling, General and Administrative Expenses
Selling, general and administrative expenses consist primarily of personnel costs, including those personnel costs 
associated with the direct sales and marketing force and our patient support program for ZURZUVAE, as well as salaries, 
benefits and travel expenses for our executive, finance, business, commercial, corporate development and other 
administrative functions, and stock-based compensation expense. Selling, general and administrative expenses also 
include professional fees for expenses incurred under agreements with third parties relating to the commercialization of 
ZURZUVAE; ongoing launch activities related to ZURZUVAE; public relations, audit, tax and legal services, including 
legal expenses to pursue patent protection of our intellectual property; and a portion of our information technology, 
facilities and other related expenses, including rent, depreciation, maintenance of facilities, insurance and supplies. 
We have an active field sales force supported by experienced sales leadership teams and professionals in marketing, 
access and reimbursement, managed markets, market research, commercial operations, and sales force planning, and 
management dedicated to commercialization of ZURZUVAE. We expect to continue to incur significant 
commercialization expenses, including payroll and related expenses, to support ongoing commercialization activities 
associated with ZURZUVAE.
As a result of the 2024 Restructuring, we expect that our selling, general and administrative expenses will decrease 
in 2025 as compared to 2024. However, we expect to continue to incur significant selling, general and administrative 
expenses as we and our collaboration partner, Biogen, continue to commercialize ZURZUVAE in the U.S. for the 
treatment of women with PPD. These expenses include the personnel costs associated with the direct sales and marketing 
force for ZURZUVAE and our patient support program for ZURZUVAE. For example, we recently completed a strategic 
expansion of our sales force, where we believe additional resources will help accelerate demand for ZURZUVAE for the 
treatment of women with PPD. In addition, our current commercialization investment plan includes joint sales force 
expansions and planned digital marketing campaigns to help expand market growth in PPD, along with increased disease 
state awareness efforts to support improved PPD screening and diagnosis. Additionally, we expect to incur significant 
expenses from the progression of our development efforts for our current or future product candidates and 
commercialization of those products, if successfully developed and approved. We also expect to continue to incur 
significant expenses associated with general operations, including costs related to accounting and legal services, director 
and officer insurance premiums, facilities and other corporate infrastructure and office-related costs, such as information 
technology costs.
We consider the collaborative activities associated with the co-development, co-commercialization, and co-
manufacturing of the Licensed 217 Products and, through the SAGE-324 Termination effective date, the Licensed 324 
Products in the U.S. to be separate units of account within the scope of Topic 808 as we and Biogen are both active 
participants in the development and commercialization activities and are exposed to significant risks and rewards that are 
dependent on the development and commercial success of the activities in the arrangement. Payments to or 
reimbursements from Biogen related to the co-commercialization activities are accounted for as an increase to or 
reduction of selling, general and administrative expense. During the years ended December 31, 2024 and 2023, we 
recorded net reimbursement from us to Biogen of $10.9 million and $16.5 million, respectively, that was added to our 
selling, general and administrative expenses. During the year ended December 31, 2022, we recorded net reimbursement 
from Biogen to us of $2.2 million that was deducted from our selling, general and administrative expenses.
2023 Restructuring
In August 2023, we implemented a strategic corporate reorganization and reprioritization of our pipeline, or the 
2023 Restructuring. The reorganization included a reduction of our workforce by approximately 40%, designed to right-
size the organization as we worked to achieve sustained growth and support the goal of successful commercialization of 
ZURZUVAE for the treatment of women with PPD. As of December 31, 2024, we recorded a total of $32.9 million of 
expense related to the 2023 Restructuring, primarily for one-time termination benefits to the affected employees and, 
primarily consisting of cash payments of severance, healthcare benefits and outplacement assistance. Substantially all of 
the accrued restructuring charges incurred in connection with the 2023 Restructuring have been paid in cash as of 
December 31, 2024.

103
2024 Restructuring
In October 2024, we implemented the 2024 Restructuring to focus investment on the ongoing launch of 
ZURZUVAE for the treatment of women with PPD and prioritized pipeline development efforts. The reorganization 
included a reduction of approximately 33% of our total workforce and approximately 55% of our research and 
development workforce. As a result, we expect that our operating expenses will decrease in 2025 as compared to 2024. 
During the year ended December 31, 2024, we recorded a total of $22.3 million of expense related to the 2024 
Restructuring, primarily for one-time termination benefits to the affected employees, primarily consisting of cash 
payments of severance, healthcare benefits and outplacement assistance. We expect to incur an additional $1.3 million of 
expense related to the 2024 Restructuring in future periods. We expect that substantially all of the accrued restructuring 
charges incurred for the year ended December 31, 2024 will be paid in cash as of June 30, 2025.
Critical Accounting Policies and Significant Judgments and Estimates
Our consolidated financial statements are prepared in accordance with generally accepted accounting principles in 
the U.S. The preparation of our consolidated financial statements and related disclosures requires us to make estimates 
and assumptions that affect the reported amount of assets, liabilities, revenue, costs and expenses, and related disclosures. 
We believe that the estimates and assumptions involved in the accounting policies described below may have the greatest 
potential impact on our consolidated financial statements and, therefore, consider these to be our critical accounting 
policies. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ from these 
estimates under different assumptions and conditions. While our significant accounting policies are described in more 
detail in the Notes to our Consolidated Financial Statements appearing elsewhere in this Annual Report, we believe that 
the following accounting policies are those most critical to the judgments and estimates used in the preparation of our 
consolidated financial statements.
Revenue Recognition
Under ASC Topic 606, Revenue from Contracts with Customers, or Topic 606, an entity recognizes revenue when or 
as performance obligations are satisfied by transferring control of promised goods or services to a customer, in an amount 
that reflects the consideration that the entity expects to receive in exchange for those goods or services. To determine 
revenue recognition for arrangements that an entity determines are within the scope of Topic 606, the entity performs the 
following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; 
(iii) determine the transaction price, including variable consideration, if any; (iv) allocate the transaction price to the 
performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance 
obligation. Arrangements that include rights to additional goods or services that are exercisable at a customer’s discretion 
are generally considered options. We assess if these options provide a material right to the customer and if so, they are 
considered performance obligations. The exercise of a material right may be accounted for as a contract modification or as 
a continuation of the contract for accounting purposes. 
For contracts determined to be within the scope of Topic 606, we assess whether the goods or services promised 
within each contract are distinct to identify those that are performance obligations. This assessment involves subjective 
determinations and requires management to make judgments about the individual promised goods or services and whether 
such are separable from the other aspects of the contractual relationship. Promised goods and services are considered 
distinct provided that: (i) the customer can benefit from the good or service either on its own or together with other 
resources that are readily available to the customer and (ii) the entity’s promise to transfer the good or service to the 
customer is separately identifiable from other promises in the contract. 
We allocate the transaction price (the amount of consideration we expect to be entitled to from a customer in 
exchange for the promised goods or services) to each performance obligation and recognize the associated revenue when 
(or as) each performance obligation is satisfied. Our estimate of the transaction price for each contract includes all 
variable consideration to which we expect to be entitled.

Product Revenue, Net
In 2024, we generated product revenue from the sale of ZULRESSO to a limited number of specialty distributors 
and specialty pharmacy providers. We recognized product revenue, net of variable consideration related to certain 
allowances and accruals that are determined using the expected value method, in our consolidated financial statements at 
the point in time when control transfers to the customer, which is typically when the product was delivered to the 
customer’s location. The amount included in the transaction price was constrained to the amount for which it was 
probable that a significant reversal of cumulative revenue recognized would not occur. Our only performance obligation 
identified for ZULRESSO was to deliver the product to the location specified by the customer’s order. We recorded 
shipping and handling costs associated with delivery of product to our customers within selling, general and 
administrative expenses on our consolidated statements of operations and comprehensive loss. We expensed incremental 
costs of obtaining a contract as incurred if the expected amortization period of the asset would be less than one year. If we 
had incurred incremental costs with an amortization period greater than a year, such costs would have been capitalized as 
contract assets, as they are expected to be recovered, and would be expensed by amortizing on a systematic basis that is 
consistent with the transfer to the customer of the goods or services to which the asset relates. We did not have any 
contract assets (unbilled receivables) at December 31, 2024, as customer invoicing generally occurred before or at the 
time of revenue recognition. The Company did not have any contract liabilities at December 31, 2024, as we did not 
receive any payments in advance of satisfying our performance obligations to our customers. Amounts billed or invoiced 
that are considered trade accounts receivable are included in prepaid expenses and other current assets on the consolidated 
balance sheets. 
As of December 31, 2024 and 2023, we had not provided any allowance for bad debts against the trade accounts 
receivable, and the amount of trade accounts receivable was not significant.
We recorded reserves, based on contractual terms, for the following components of variable consideration related to 
product sold during the reporting period, as well as our estimate of product that remains in the distribution channel 
inventory of our customers at the end of the reporting period. On a quarterly basis, we updated our estimates, if necessary, 
and recorded any material adjustments in the period they were identified.
Chargebacks: We estimated chargebacks from our customers who directly purchased the product from us for 
discounts resulting from contractual commitments to sell products to eligible healthcare settings at prices lower 
than the list prices charged to our customers. Customers charged us for the difference between what they paid to 
us for the product and the selling price to the eligible healthcare settings. Reserves for chargebacks consist of 
credits that we expected to issue for units that remained in the distribution channel inventories at the end of each 
reporting period that we expected would be sold to eligible healthcare settings, and chargebacks that customers 
have claimed, but for which we have not yet issued a credit.
Government Rebates: We are subject to discount obligations under government programs, including Medicaid. 
We recorded reserves for rebates in the same period the related product revenue was recognized, resulting in a 
reduction of ZULRESSO product revenue and a current liability that is included in accrued expenses on our 
consolidated balance sheets. Our liability for these rebates consisted of invoices received for claims from prior 
quarters that have not been paid or for which an invoice has not yet been received, estimates of claims for the 
current quarter, and estimates of future claims that will be made for product that has been recognized as revenue, 
but which remained in the distribution channel at the end of each reporting period.
Trade Discounts and Allowances: We generally provided customary invoice discounts on ZULRESSO sales to 
our customers for prompt payment and we paid fees for sales order management, data, and distribution services. 
We estimated our customers will earn these discounts and fees and deducted these discounts and fees in full from 
gross ZULRESSO revenue and accounts receivable at the time we recognized the related revenue.
Financial Assistance: We provide voluntary financial assistance programs to patients with commercial insurance 
that have coverage and reside in states that allow financial assistance. We estimated the financial assistance 
amounts for ZULRESSO and recorded any such amounts within accrued expenses on the consolidated balance 
sheets. The calculation of the accrual for financial assistance was based on an estimate of claims and the cost per 
claim that we expected to receive using demographics for patients who had registered and been approved for 
assistance. Any adjustments were recorded in the same period the related revenue was recognized, resulting in a 

105
reduction of product revenue and the establishment of a current liability, which was included as a component of 
accrued expenses on the consolidated balance sheets.
Product Returns: Consistent with industry practice, we offer product return rights to customers for damaged, 
defective or expiring product, provided it is within a specified period around the product expiration date as set 
forth in our return goods policy. We estimated the amount of our product sales that may be returned by our 
customers and recorded this estimate as a reduction of revenue in the period the related product revenue was 
recognized, as well as a reserve within accrued expenses on our consolidated balance sheets. Product returns have 
not been significant to date and are not expected to be significant in the future.
License, Milestone, and Collaboration Revenue
In assessing whether a promised good or service is distinct in the evaluation of a collaboration or license 
arrangement subject to Topic 606, we consider factors such as the research, manufacturing and commercialization 
capabilities of the collaboration partner, and the availability of the associated expertise in the general marketplace. We 
also consider the intended benefit of the contract in assessing whether a promised good or service is separately identifiable 
from other promises in the contract. If a promised good or service is not distinct, we are required to combine that good or 
service with other promised goods or services until we identify a bundle of goods or services that is distinct.
The transaction price is then determined and allocated to the identified performance obligations in proportion to their 
standalone selling prices, or SSP, on a relative SSP basis. SSP is determined at contract inception and is not updated to 
reflect changes between contract inception and when the performance obligations are satisfied. Determining the SSP for 
performance obligations requires significant judgment. In developing the SSP for a performance obligation, we consider 
applicable market conditions and relevant entity-specific factors, including factors that were contemplated in negotiating 
the agreement with the customer and estimated costs. In certain circumstances, we may apply the residual method to 
determine the SSP of a good or service if the standalone selling price is considered highly variable or uncertain. We 
validate the SSP for performance obligations by evaluating whether changes in the key assumptions used to determine the 
SSP will have a significant effect on the allocation of arrangement consideration between multiple performance 
obligations.
If the consideration promised in a contract includes a variable amount, we estimate the amount of consideration to 
which we will be entitled in exchange for transferring the promised goods or services to a customer. We determine the 
amount of variable consideration by using the expected value method or the most likely amount method. We include the 
unconstrained amount of estimated variable consideration in the transaction price. The amount included in the transaction 
price is constrained to the amount for which it is probable that a significant reversal of cumulative revenue recognized will 
not occur. At the end of each subsequent reporting period, we re-evaluate the estimated variable consideration included in 
the transaction price and any related constraint, and if necessary, adjust our estimate of the overall transaction price. Any 
such adjustments are recorded on a cumulative catch-up basis in the period of adjustment.
If an arrangement includes development and regulatory milestone payments, we evaluate whether the milestones are 
considered probable of being reached and estimate the amount to be included in the transaction price using the most likely 
amount method. If it is probable that a significant revenue reversal would not occur, the associated milestone value is 
included in the transaction price. Milestone payments that are not within our control or the licensee’s control, such as 
regulatory approvals, are generally not considered probable of being achieved until those approvals are received.
In determining the transaction price, we adjust consideration for the effects of the time value of money if the timing 
of payments provides us with a significant benefit of financing. We do not assess whether a contract has a significant 
financing component if the expectation at contract inception is such that the period between payment by the licensees and 
the transfer of the promised goods or services to the licensees will be one year or less. We assessed our arrangements with 
Shionogi and Biogen and concluded that a significant financing component does not exist for either arrangement. For 
arrangements with licenses of intellectual property that include sales-based royalties or milestone payments based on the 
level of sales, and the license is deemed to be the predominant item to which the royalties or milestone payments relate, 
we recognize royalty revenue and sales-based milestones at the later of (i) when the related sales occur, or (ii) when the 
performance obligation to which the royalty or milestone payment has been allocated has been satisfied.

106
We then recognize as revenue the amount of the transaction price that is allocated to the respective performance 
obligation when (or as) each performance obligation is satisfied at a point in time or over time, and if over time this is 
based on the use of an output or input method. For additional information, see Collaborative Arrangements section below 
and refer to Note 7, Collaboration Agreements, to our Consolidated Financial Statements appearing elsewhere in this 
Annual Report.
Collaborative Arrangements
We analyze our collaboration arrangements to assess whether such arrangements involve joint operating activities 
performed by parties that are both active participants in the activities and exposed to significant risks and rewards 
dependent on the commercial success of such activities and therefore within the scope of Topic 808. This assessment is 
performed throughout the life of the arrangement based on changes in the responsibilities of all parties in the arrangement. 
For collaboration arrangements within the scope of Topic 808 that contain multiple elements, we first determine which 
elements of the collaboration are deemed to be within the scope of Topic 808 and which elements of the collaboration are 
more reflective of a vendor-customer relationship and therefore within the scope of Topic 606. For elements of 
collaboration arrangements that are accounted for pursuant to Topic 808, an appropriate recognition method is determined 
and applied consistently, either by analogy to authoritative accounting literature or by applying a reasonable and rational 
policy election. For those elements of the arrangement that are accounted for pursuant to Topic 606, we apply the five-
step model described above and presents the arrangement as license and milestone revenue or other collaboration revenue 
in the consolidated statements of operations and comprehensive loss.
For collaboration arrangements that are within the scope of Topic 808, we evaluate the income statement 
classification for presentation of amounts due from or owed to other participants associated with multiple activities in a 
collaboration arrangement based on the nature of each separate activity. Payments or reimbursements that are the result of 
a collaborative relationship, instead of a customer relationship are recorded as an increase to collaboration revenue, an 
increase to or reduction of research and development expense or selling, general and administrative expense, depending 
on the nature of the activity.
Accrued Research and Development Expenses
As part of the process of preparing our consolidated financial statements, we are required to estimate our accrued 
research and development expenses. This process involves reviewing open contracts and purchase orders, communicating 
with our personnel and vendors to identify services that have been performed on our behalf and estimating the level of 
service performed and the associated costs incurred for the services when we have not yet been invoiced or otherwise 
notified of the actual costs. The majority of our service providers invoice us in arrears for services performed, on a pre-
determined schedule or when contractual milestones are met; however, some require advance payments. We make 
estimates of our accrued expenses as of each balance sheet date in our consolidated financial statements based on facts 
and circumstances known to us at that time. Examples of estimated accrued research and development expenses include 
fees paid to:
•
CROs in connection with performing research and development services on our behalf;
•
other providers in connection with clinical trials;
•
vendors in connection with non-clinical development activities; and
•
vendors related to product manufacturing, development and distribution of clinical supplies.
We base our expenses related to clinical trials on our estimates of the services received and efforts expended 
pursuant to contracts with multiple CROs that conduct and manage clinical trials on our behalf. The financial terms of 
these agreements vary from contract to contract and may result in uneven payment flows. There may be instances in 
which payments made to our vendors will exceed the level of services provided and result in a prepayment of the clinical 
expense. Payments under some of these contracts depend on factors such as the successful enrollment of patients and the 
completion of clinical trial milestones. When determining accruals, we estimate the time period over which services will 
be performed, enrollment of patients, number of sites activated and level of effort to be expended in each period. If the 
actual timing of the performance of services or the level of effort varies from our estimate, we adjust the accrual or 
prepaid accordingly. Although we do not expect our estimates to be materially different from amounts actually incurred, 

107
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 reporting expenses that are too high or too low in any particular period. To date, we 
have not made any material adjustments to our prior estimates of accrued research and development expenses.
Stock-Based Compensation
We recognize compensation expense for stock-based awards, including grants of stock options and restricted stock 
units, granted to employees, non-employee directors and non-employee consultants based on the estimated fair value on 
the date of grant, over the requisite service period. We recognize stock-based compensation expense for only the portion 
of awards that are expected to vest.
For awards that vest upon achievement of a performance condition, we recognize compensation expense when 
achievement of the performance condition is met or during the period from which meeting the condition is deemed 
probable until the expected date of meeting the performance condition, using management’s best estimates, which 
consider the inherent risk and uncertainty regarding the future outcomes of the milestones.
The fair value of each stock option grant is estimated using the Black-Scholes option-pricing model. We use the 
historical volatility of only our common stock, as there is adequate historical data for the duration of the expected term. 
The expected term of the stock options granted to employees, non-employee directors and non-employee consultants 
by us has been determined utilizing the “simplified” method for awards that qualify as “plain-vanilla” stock options. The 
risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the date of grant for time 
periods approximately equal to the expected term of the award. The expected dividend yield is zero, based on the fact that 
we have never paid cash dividends and do not expect to pay any cash dividends in the foreseeable future.
We also apply a forfeiture rate in order to calculate stock-based compensation expense. Expected forfeitures are 
based on our historical experience and management’s expectations of future forfeitures. To the extent actual forfeitures 
differ from the estimates, the difference is recorded as a cumulative adjustment in the period in which the estimates are 
revised.
The fair value of each stock option granted under our equity plans has been calculated on the date of grant using the 
following weighted average assumptions:
Year Ended December 31,
2024
2023
2022
Expected dividend yield
0%
0%
0%
Expected volatility

73%
Risk-free interest rate
4.24%
3.85%
2.49%
Expected term
6.01 years
6.01 years
6.03 years
These assumptions represented our best estimates, but the estimates involve inherent uncertainties and the 
application of our judgment. As a result, if factors change and we use significantly different assumptions or estimates 
when valuing our stock options, our stock-based compensation expense could be materially different. In developing a 
forfeiture rate estimate for pre-vesting forfeitures, we have considered our historical experience of actual forfeitures. In 
the future, if our actual forfeiture rate is materially different from our estimate, then our stock-based compensation 
expense could be significantly different from what we have recognized in the current period.
As of December 31, 2024, we had unrecognized stock-based compensation expense related to our outstanding and 
unvested time-based stock option awards of $24.1 million, which is expected to be recognized over the remaining 
weighted average vesting period of 3.18 years.

108
As of December 31, 2024, 455,000 performance-based stock options were both outstanding and unvested, the total 
unrecognized stock-based compensation expense related to these awards was $24.9 million and the timing of recognition 
of this stock-based compensation expense is subject to our judgment as to when the performance conditions are 
considered probable of being achieved.
As of December 31, 2024, 1,788,137 time-based restricted stock units were both outstanding and unvested, and the 
total unrecognized stock-based compensation expense related to these awards was $13.8 million.
As of December 31, 2024, 1,212,253 performance restricted stock units were both outstanding and unvested, and the 
total unrecognized stock-based compensation expense related to these awards was $42.9 million.

Product Revenue, Net
During the years ended December 31, 2024 and 2023, we recognized $3.6 million and $10.5 million, respectively, of 
net product revenue related to sales of ZULRESSO. Sales allowances and accruals consisted of chargebacks, discounts, 
distribution fees and patient financial assistance, and were not significant during either year.
License and Milestone Revenue - Related Party
During the year ended December 31, 2024, we recognized no license and milestone revenue - related party under the 
Biogen Collaboration Agreement.
During the year ended December 31, 2023, we recognized $75.0 million of license and milestone revenue - related 
party for the achievement of a milestone under the Biogen Collaboration Agreement for the first commercial sale of 
ZURZUVAE for the treatment of women with PPD in the U.S.
Collaboration Revenue - Related Party
During the years ended December 31, 2024 and 2023, we recognized $36.1 million and $0.8 million, respectively, of 
collaboration revenue - related party for our share of Biogen’s net ZURZUVAE sales to customers in the U.S. under the 
Biogen Collaboration Agreement. To record our share of collaboration revenue – related party from the sales of 
ZURZUVAE, we utilize certain information from Biogen, including revenue from the sale of the product and associated 
reserves. Reported collaboration revenue - related party is 50% of the net sales Biogen reports for ZURZUVAE.
Other Collaboration Revenue
During the years ended December 31, 2024 and 2023, we recognized $0.6 million and $0.2 million, respectively, 
of other collaboration revenue related to the supply of zuranolone active pharmaceutical ingredients under our agreement 
with Shionogi.
During the year ended December 31, 2024, we recognized $0.9 million of other collaboration revenue related to 
providing development and regulatory support to Biogen in the Biogen Territory under the Biogen Collaboration 
Agreement. During the year ended December 31, 2023, we did not recognize any other collaboration revenue under the 
Biogen Collaboration Agreement.
We expect that further revenue, if any, that we may generate under our collaboration agreements will fluctuate from 
quarter to quarter as a result of the timing and amount of our share of collaboration revenues resulting from Biogen’s sales 
of any commercialized products, license fees, payments for clinical materials or manufacturing services, milestone 
payments, royalties paid to us, and other payments. For further discussion regarding our collaboration agreements with 
Shionogi and Biogen and the accounting for revenue from collaboration agreements, refer to Note 2, Summary of 
Significant Accounting Policies; and Note 7, Collaboration Agreements in the Notes to Consolidated Financial Statements 
appearing elsewhere in this Annual Report. 
Cost of Revenues
During the years ended December 31, 2024 and 2023, cost of revenues was $9.4 million and $2.2 million, 
respectively, and is made up of direct and indirect costs related to the manufacturing and distribution of ZULRESSO 
including third-party manufacturing costs, packaging services, freight, third-party royalties payable on our net product 
revenue of ZULRESSO and amortization of intangible assets associated with ZULRESSO. During the year ended 
December 31, 2024, we incurred $3.6 million of one-time charges related to the write-off of excess inventory and 
impairment of intangible assets related to ZULRESSO as a result of the decision to discontinue commercial availability in 
the U.S. as of December 31, 2024. Cost of revenues may also include period costs related to certain inventory 
manufacturing services and inventory adjustment charges. Cost of revenues also includes our proportionate share of 
ZURZUVAE manufacturing costs under the Biogen Collaboration Agreement (for further discussion regarding our 
collaboration agreement with Biogen and the accounting for collaboration agreements, refer to Note 2, Summary of 

110
Significant Accounting Policies; and Note 7, Collaboration Agreements in the Notes to Consolidated Financial Statements 
appearing elsewhere in this Annual Report).
Prior to receiving FDA approval for ZULRESSO in March 2019, we manufactured ZULRESSO inventory to be sold 
upon commercialization and recorded $8.9 million related to this inventory build-up as research and development 
expense. As a result, the manufacturing costs related to the ZULRESSO inventory build-up incurred before FDA approval 
were already expensed in a prior period and therefore a portion of such costs are excluded from the cost of revenues for 
the years ended December 31, 2024 and 2023. Our cost of revenues for ZULRESSO as a percentage of net product 
revenue remained in the high-single digit to low-double digits percentage range for the duration of ZULRESSO’s 
commercial availability. We utilized zero-cost inventory with respect to ZULRESSO during this period.

Research and development expenses for the year ended December 31, 2024 were $225.9 million, compared to 
$356.2 million for the year ended December 31, 2023. The decrease of $130.3 million was primarily due to the following:
•
a decrease of $101.8 million in expenses for development of zuranolone, primarily due to expenses incurred 
during the year ended December 31, 2023 related to ongoing clinical trial costs that did not occur in 2024, and 
cost savings in 2024 resulting from the cancelation of excess purchase commitments for manufacturing as a 
result of the CRL received from the FDA related to the NDA for zuranolone for the treatment of MDD;
•
a decrease of $12.1 million in expenses for development of SAGE-324, primarily due to activities directed 
towards the conduct of two Phase 2 clinical trials which were initiated in late 2022, conducted throughout the 
year ended December 31, 2023, and were concluded during the year ended December 31, 2024, resulting in 
lower expense in 2024; 
•
a decrease of $27.4 million in expenses for other research and development programs, primarily due to the 
pipeline prioritization cost saving initiatives of the 2024 Restructuring and 2023 Restructuring; 
•
a decrease of $45.9 million in unallocated expenses, primarily due to the effects of a decreased headcount in 
2024 and overhead cost savings initiatives resulting from the 2023 Restructuring; 
•
a decrease of $5.9 million in stock-based compensation expenses, primarily due to the recognition of $2.5 
million of expense for the achievement of one performance-based vesting criteria and probable achievement of 
another performance-based vesting criteria during the year ended December 31, 2024, as compared to $6.9 
million of expense for the vesting of three performance-based vesting criteria during the year ended 
December 31, 2023 and decreased expense for time-based stock options and restricted stock units during the 
year ended December 31, 2024, as compared to the year ended December 31, 2023 as a result of lower 
headcount after the 2024 Restructuring; and
•
a decrease of $60.5 million in the net reimbursement from Biogen pursuant to the Biogen Collaboration 
Agreement. For the year ended December 31, 2024, the amount of net reimbursement was $1.3 million for 

111
zuranolone, $10.6 million for SAGE-324 and $3.8 million for costs that are reimbursable and included in 
unallocated expenses. For the year ended December 31, 2023, the amount of net reimbursement was $51.1 
million for zuranolone, $16.3 million for SAGE-324 and $8.8 million for costs that are reimbursable and 
included in unallocated expenses. The primary reason for the decrease in net reimbursement in 2024 compared 
to 2023 was the decrease in spending for zuranolone, primarily due to expenses related to the completion of 
ongoing clinical trials during the year ended December 31, 2023, and canceling excess purchase commitments 
for manufacturing as a result of the CRL received from the FDA related to the NDA for zuranolone for the 
treatment of MDD.

Selling, general and administrative expenses for the year ended December 31, 2024, were $216.4 million, compared 
to $274.5 million for the year ended December 31, 2023. The decrease of $58.1 million was primarily due to the 
following:
•
a decrease of $19.9 million in personnel-related costs, primarily due to the effects of a decreased headcount in 
2024 resulting from the 2023 Restructuring;
•
a decrease of $12.1 million in non-cash stock-based compensation expense, primarily due to the recognition of 
$5.1 million of expense for the achievement of one performance-based vesting criteria and probable 
achievement of another performance-based vesting criteria during the year ended December 31, 2024, as 
compared to $18.1 million of expense for the vesting of three performance-based vesting criteria during the 
year ended December 31, 2023 for a decrease of $13.0 million. The decrease in performance-based stock-
compensation expense was partially offset by a $0.9 million increase to time-based grants of stock options and 
restricted stock units during the year ended December 31, 2024 as compared to the year ended December 31, 
2023;

112
•
a decrease of $4.6 million in professional fees, primarily due to a reduction in pre-launch readiness spend and 
decreased investment in commercial spend following the CRL received from the FDA related to the NDA for 
zuranolone for the treatment of MDD;
•
a decrease of $15.9 million in other fees, primarily due to the implementation of cost saving initiatives as part 
of the 2023 Restructuring; and
•
a decrease of $5.6 million in the net reimbursement to Biogen pursuant to the Biogen Collaboration 
Agreement. For the year ended December 31, 2024, the amount of net reimbursement from us to Biogen was 
$10.7 million for external costs and $0.2 million for personnel-related costs. For the year ended December 31, 
2023, the amount of net reimbursement from us to Biogen was $16.4 million for external costs and $0.1 
million for personnel-related costs. The primary reason for the decrease in net reimbursement was a decrease in 
the collaboration costs incurred by Biogen following the CRL received from the FDA related to the NDA for 
zuranolone for the treatment of MDD.
Restructuring
Restructuring expense for the years ended December 31, 2024 and 2023, was $21.9 and $33.4 million, respectively. 
The primary reason for the decrease in 2024 as compared to 2023 was the headcount reduction resulting from the 2024 
Restructuring during the year ended December 31, 2024 was smaller as compared to the 2023 Restructuring during the 
year ended December 31, 2023.
Interest Income, Net and Other Income, Net
Interest income, net, and other income, net, for the years ended December 31, 2024 and 2023, were $31.7 million 
and $38.4 million, respectively. The primary reason for the decrease in 2024 as compared to 2023 was the decrease in 
total balance of marketable securities during the year ended December 31, 2024 as compared to the year ended 
December 31, 2023.
Liquidity and Capital Resources
We began to generate revenue from product sales in the second quarter of 2019 in conjunction with the commercial 
launch of our first product, ZULRESSO, in June 2019 for the treatment of PPD in the U.S. We began to generate 
collaboration revenue from product sales of ZURZUVAE for the treatment of women with PPD in the U.S. in December 
2023. We have incurred net losses in each year since our inception, except for net income of $606.1 million for the year 
ended December 31, 2020, reflecting revenue recognized under the Biogen Collaboration Agreement. As of December 31, 
2024, we had an accumulated deficit of $3.0 billion. On December 31, 2020, we completed the sale of 6,241,473 shares of 
our common stock in a private placement to BIMA at a price of approximately $104.14 per share, resulting in aggregate 
gross proceeds of $650.0 million. In January 2024, we received a $75.0 million milestone payment from Biogen as a 
result of the first commercial sale of ZURZUVAE for the treatment of women with PPD in the U.S. in the fourth quarter 
of 2023. From our inception through December 31, 2024, we have received aggregate net proceeds of $2.8 billion from 
the sales of redeemable convertible preferred stock prior to our initial public offering, the issuance of convertible notes, 
and the sales of common stock in our initial public offering in July 2014, follow-on offerings and in the sale of shares of 
our common stock to Biogen in connection with the Biogen Collaboration Agreement, which we refer to as the Biogen 
Equity Purchase. We also received $1.0 billion in upfront payments under our collaborations with Biogen and Shionogi.

113
In September 2024, we entered into a Sales Agreement, or the ATM Sales Agreement, with TD Securities (USA) 
LLC, as sales agent, or TD Cowen, with respect to an “at the market offering” program pursuant to which we may offer 
and sell shares of our common stock having an aggregate offering price of up to $250.0 million, from time to time through 
TD Cowen. Upon our entry into the ATM Sales Agreement, we terminated our prior sales agreement with Cowen and 
Company, LLC, an affiliate of TD Cowen, dated November 7, 2023, or the Original Sales Agreement. At the time of such 
termination, $241.7 million out of an aggregate of $250.0 million of shares remained unsold under the Original Sales 
Agreement. During the year ended December 31, 2024, we did not sell any shares under the ATM Sales Agreement. 
During the year ended December 31, 2024, we sold an aggregate of 700,000 shares under the Original Sales Agreement at 
an average price per share of $11.90 and received gross proceeds of approximately $8.3 million, before deducting 
commissions, underwriting discounts, and offering costs of $0.3 million. As of December 31, 2024, $250.0 million of 
shares remained available for issuance and sale under the ATM Sales Agreement. 
As of December 31, 2024, our primary sources of liquidity were our cash, cash equivalents and marketable 
securities, which totaled $504.4 million. We invest our cash in money market funds, U.S. government securities, corporate 
bonds, commercial paper, certificates of deposit and municipal securities, and our primary objectives are to preserve 
principal, provide liquidity and maximize income without significantly increasing risk.
The following table summarizes the primary sources and uses of cash for the years ended December 31, 2024 and 
2023:

Operating Activities
During the year ended December 31, 2024, net cash used in operating activities primarily resulted from our net loss 
of $400.7 million, which was primarily attributable to our research and development activities and our selling, general and 
administrative expenses, partially offset by changes in our operating assets and liabilities of $84.8 million and $48.7 
million of non-cash items. 
During the year ended December 31, 2023, net cash used in operating activities primarily resulted from our net loss 
of $541.5 million, which was primarily attributable to our research and development activities and our selling, general and 
administrative expenses, along with changes in our operating assets and liabilities of $67.4 million, partially offset by 
$68.3 million of non-cash items.
Investing Activities
During the years ended December 31, 2024 and 2023, net cash provided by investing activities was $266.7 million 
and $442.9 million, respectively. During the years ended December 31, 2024 and 2023, we purchased marketable 
securities and had sales and maturities of our marketable securities as part of managing our cash and investments 
portfolio.
Financing Activities
During the years ended December 31, 2024 and 2023, net cash provided by financing activities was $10.7 million 
and $6.0 million, respectively. The increase was primarily due to proceeds from the sale of shares of our common stock 
pursuant to the Original Sales Agreement in 2024, partially offset by a decrease in proceeds from purchases made under 
our employee stock purchase plan.

114
Operating Capital Requirements
We anticipate that we will continue to generate losses for the foreseeable future as we commercialize ZURZUVAE, 
along with our collaboration partner Biogen, for the treatment of women with PPD in the U.S.; continue the development 
of our current and future product candidates, and seek regulatory approvals for those product candidates that are 
successfully developed; prepare for potential commercialization of any product candidates that are successfully developed 
and approved; and continue our efforts to identify and develop new product candidates beyond our current portfolio. We 
also expect to incur significant costs associated with general operations. In addition, we expect to incur significant 
commercialization expenses for product sales, marketing and outsourced manufacturing with respect to ZURZUVAE and 
any other future products that are successfully developed and approved. Accordingly, we anticipate that we will need 
substantial additional funding in connection with our continuing operations.
Based upon our current operating plan, we anticipate that our existing cash, cash equivalents and marketable 
securities as of December 31, 2024, together with anticipated funding from our ongoing collaborations and estimated 
revenues, excluding any potential milestone payments we may receive under our collaboration agreements, will support 
our operations to mid-2027. We have based this estimate on assumptions that may prove to be wrong, such as the revenue 
that we expect to realize from our collaboration agreement for the continued commercialization of ZURZUVAE. To the 
extent estimated revenue levels are not realized, we may adjust our operating plan accordingly, including the deferral or 
reduction of planned operating expenses, as needed. 
Although we expect an overall decrease in our operating expenses in 2025 as compared to 2024 as a result of our 
pipeline prioritization and the anticipated cost savings from the 2024 Restructuring, we still expect to incur significant 
operating expenses, including in connection with our efforts to commercialize ZURZUVAE in the U.S. for the treatment 
of women with PPD. We expect these costs will include the expenses associated with: ongoing co-commercialization 
activities; conducting clinical trials of our other current and future product candidates; continuing certain research 
activities; pursuing potential business development activities; and pursuing our strategic plan.
Our current operating plan does not contemplate other activities that we may pursue or that all of our currently 
planned activities will proceed at the same pace, or that all of these activities will be fully initiated or completed during 
that time. We have based our estimates on assumptions that could change, such as the revenue that we expect to generate, 
or the clinical development costs we expect to incur, particularly as the process of testing drug candidates in clinical trials 
is costly and the timing of progress in these trials is uncertain. As a result, we may use our available capital resources 
sooner than we currently expect and may need to adjust our plans accordingly. We may also choose to change or increase 
our development, commercialization or other efforts or incur significant unanticipated expenses. Because of the numerous 
risks and uncertainties associated with the development and commercialization of any product or product candidates, we 
are unable to estimate the amounts of increased capital outlays and operating expenditures necessary to complete 
development of our current or future product candidates or to commercialize any approved product.
Our future capital requirements will depend on many factors, including: 
•
our ability, with our collaborator Biogen, to successfully commercialize ZURZUVAE for the treatment of 
women with PPD in the U.S., and the timing and amount of costs associated with commercialization; the 
timing and amount of revenues from sales of ZURZUVAE; the level of reimbursement for ZURZUVAE both 
by commercial and government payors, and the nature of any potential limitations on coverage and 
reimbursement; and the degree of market acceptance of ZURZUVAE by healthcare professionals and women 
with PPD;
•
the impact of the 2024 Restructuring;
•
the impact of our decision to discontinue commercial availability of ZULRESSO in the U.S. as of December 
31, 2024;
•
the initiation, progress, completion, timing, costs, and results of ongoing, planned and future non-clinical 
studies and clinical trials for our existing and future product candidates; the number and length of clinical trials 
required by regulatory authorities to support regulatory approval; and the costs of preparing, submitting and 
supporting regulatory filings for our product candidates, if our development efforts are successful;

115
•
general macroeconomic and geopolitical conditions, including any capacity and resource constraints at our 
vendors and clinical trial sites on initiation and conduct of our clinical trials or on our supply chain; 
•
the ability of our product candidates to progress through development successfully and on the timelines we 
expect; the outcome of discussions with regulatory authorities on regulatory pathways with respect to our 
product candidates, including the number and length of clinical trials required to support regulatory approval; 
the timing, scope and outcome of regulatory filings and reviews and approvals of such product candidates, if 
we are successful in our development efforts; the scope and cost of any clinical trials or other commitments 
required post-approval for any approved products resulting from such development efforts, if successful; and 
the level, timing and amount of costs associated with permitted prelaunch activities and preparing for a 
potential future commercial launch of any such product candidate that is successfully developed and approved;
•
the impact of current and future products developed by third parties that may compete with our current or 
future marketed products;
•
the amounts we are entitled to receive, if any, from Biogen and Shionogi under our collaborations for profit-
sharing, cost-sharing, development, regulatory, and sales milestones, and royalty payments;
•
the size of the markets for which our products are approved and in the indications we are pursuing or plan to 
study with our product candidates; the portion of the population in the approved indications for our products 
that are actually prescribed; and the rate and degree of market acceptance, pricing, and availability and level of 
reimbursement for our products and product candidates, if successfully developed and approved;
•
the number and characteristics of the product candidates we pursue in development and the nature and scope of 
our discovery and development programs;
•
the costs of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual 
property rights and defending intellectual property-related claims;
•
the extent to which we acquire or in-license other products and technologies; and
•
our ability to establish any future collaboration arrangements on favorable terms, if at all.
Until such time, if ever, as we can generate substantial product revenue and/or collaboration revenue and achieve 
sustained profitability, we will need additional financing. We expect to finance our additional cash needs through a 
combination of equity offerings, debt financings, collaborations, strategic alliances, licensing or royalty arrangements and 
other sources of funding. Even if we believe we have sufficient funds for our current or future operating plans, we may 
seek additional capital if market conditions are favorable or in light of other strategic considerations. To the extent that we 
raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our 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, 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 and may require the issuance of warrants, which could potentially dilute the ownership interest of our 
stockholders. If we raise additional funds through collaborations, strategic alliances, licensing or royalty arrangements or 
other agreements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams 
or research programs or to grant licenses on terms that may not be favorable to us. Raising funds may present challenges. 
Markets may experience volatility or become disrupted in the future for any number of reasons, including as a result of 
macroeconomic or geopolitical conditions, result in an economic recession, a decrease in corporate and consumer 
expenditures, prolonged unemployment, or other circumstances that could negatively impact general economic conditions. 
If we are unable to raise additional funds through equity or debt financings or other means when needed, we may be 
required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to 
develop and market products or product candidates that we would otherwise prefer to develop and market ourselves.

Amounts related to contingent milestone payments are not considered contractual obligations as they are contingent 
on the successful achievement of certain milestones. These contingent milestones may not be achieved. We have not 
included any of these amounts in the table as we cannot estimate or predict when, or if, these amounts will become due. 
We do not include amounts related to milestones for indications that we are no longer pursuing. 
(1)
We lease office space in one multi-tenant building in Cambridge, Massachusetts, consisting, as of December 31, 
2024, of 30,567 square feet, under an operating lease which commenced in August 2024 and which will expire on 
February 28, 2030. The minimum lease payments in the table do not include related common area maintenance costs 
or real estate taxes, because those costs are variable.
(2)
We enter into contracts in the normal course of business with CROs for clinical trials, non-clinical research studies 
and testing, manufacturing and other services and products as part of general operations. These contracts generally 
provide for termination upon notice, and we believe that our non-cancelable obligations under these agreements are 
not material.
Item 7A. Quantitative and Qualitative Disclosures about Market Risk
We had cash, cash equivalents and marketable securities of $504.4 million as of December 31, 2024. The primary 
objectives of our investment activities are to preserve principal, provide liquidity and maximize income without 
significantly increasing risk. Our primary exposure to market risk relates to fluctuations in interest rates, which are 
affected by changes in the general level of U.S. interest rates. Given the short-term nature of our cash, cash equivalents 
and marketable securities, we do not expect that a sudden change in market interest rates would have a material impact on 
our financial condition and/or results of operations. We do not own any derivative financial instruments. 
We contract with vendors in foreign countries and have subsidiaries in Europe, Canada, and Bermuda. As such, we 
have exposure to adverse changes in exchange rates of foreign currencies associated with our foreign transactions. We 
believe this exposure to be immaterial. We do not hedge against this exposure to fluctuations in exchange rates.
We do not believe that our cash, cash equivalents and marketable securities have significant risk of default or 
illiquidity. While we believe our cash, cash equivalents and marketable securities do not contain excessive risk, we cannot 
provide absolute assurance that in the future our investments will not be subject to adverse changes in market value. In 
addition, we maintain significant amounts of cash, cash equivalents and marketable securities that are in excess of 
federally insured limits at one or more financial institutions.
Inflation generally affects us by increasing our cost of labor and clinical trial costs. We do not believe that inflation 
had a material effect on our results of operations during the year ended December 31, 2024.

The financial statements required to be filed pursuant to this Item 8 are appended to this Annual Report. An index of 
those financial statements is found in Item 15.

Item 9A. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
We maintain disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities 
Exchange Act of 1934, as amended, or the Securities Exchange Act of 1934) 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 President and Chief Executive Officer, who is our principal 
executive officer, and our Chief Operating Officer, who is our principal financial and accounting officer, as appropriate, to 
allow timely decisions regarding required disclosure.
As of December 31, 2024, our management, with the participation of our principal executive officer and principal 
financial and accounting officer, evaluated the effectiveness of our disclosure controls and procedures. 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 and accounting 
officer have concluded, based upon the evaluation described above, that, as of December 31, 2024, 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 defined in Rule 13a-15(f) under the Securities Exchange Act of 1934). Our internal control over financial reporting is 
a process designed under the supervision of our principal executive officer and principal financial officer to provide 
reasonable assurance regarding the reliability of financial reporting and the preparation of our financial statements for 
external purposes in accordance with generally accepted accounting principles. Management evaluated the effectiveness 
of our internal control over financial reporting using the criteria set forth by the Committee of Sponsoring Organizations 
of the Treadway Commission (COSO) in Internal Control—Integrated Framework (the 2013 Framework). Management, 
under the supervision and with the participation of the principal executive officer and principal financial officer, assessed 
the effectiveness of our internal control over financial reporting as of December 31, 2024 and concluded that it was 
effective based on those criteria.
The effectiveness of our internal control over financial reporting as of December 31, 2024 has been audited by 
PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in its report, which is included 
in this Annual Report.
Changes in Internal Control over Financial Reporting
There were no changes to our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) 
under the Securities Exchange Act of 1934) that occurred during the quarter ended December 31, 2024 that have 
materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm
To the Board of Directors and Stockholders of Sage Therapeutics, Inc.
Opinions on the Financial Statements and Internal Control over Financial Reporting
We have audited the accompanying consolidated balance sheets of Sage Therapeutics, Inc. and its subsidiaries (the 
“Company”) as of December 31, 2024 and 2023, and the related consolidated statements of operations and comprehensive 
loss, of changes in stockholders’ equity and of cash flows for each of the three years in the period ended December 31, 
2024, including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited 
the Company’s internal control over financial reporting as of December 31, 2024, based on criteria established in Internal 
Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway 
Commission (COSO).
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial 
position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of 
the three years in the period ended December 31, 2024 in conformity with accounting principles generally accepted in the 
United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control 
over financial reporting as of December 31, 2024, based on criteria established in Internal Control - Integrated 
Framework (2013) issued by the COSO.
Basis for Opinions
The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal 
control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, 
included in Management’s Report on Internal Control over Financial Reporting appearing under Item 9A. Our 
responsibility is to express opinions on the Company’s consolidated financial statements and on the Company’s internal 
control over financial reporting 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 audits to obtain reasonable assurance about whether the consolidated financial statements are free of 
material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was 
maintained in all material respects.
Our audits of the consolidated financial statements included performing procedures to assess the risks of material 
misstatement of the consolidated 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 consolidated 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 consolidated financial 
statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control 
over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and 
operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other 
procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our 
opinions.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the 
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with 
generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and 
procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the 
transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are 
recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting 
principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of 
management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely 

F-2
detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the 
financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. 
Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become 
inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may 
deteriorate.
Critical Audit Matters
The critical audit matter communicated below is a matter arising from the current period audit of the consolidated 
financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to 
accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially 
challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our 
opinion on the consolidated 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.
Accrued Research and Development Costs
As described in Notes 2 and 5 to the consolidated financial statements, the Company has entered into various research and 
development contracts with research institutions and other companies. When billing terms under these contracts do not 
coincide with the timing of when the work is performed, management is required to make estimates of outstanding 
obligations to those third parties as of the end of the reporting period. Within accrued expenses, total accrued research 
and development costs amounted to $19.8 million as of December 31, 2024, which include accruals for these estimated 
ongoing research and development costs. Any accrual estimates are based on a number of factors, including 
management’s knowledge of the progress towards completion of the research and development activities, invoicing to date 
under the contracts, communication from the research institution or other companies of any actual costs incurred during 
the period that have not yet been invoiced, and the costs included in the contracts. Significant judgments and estimates 
are made in determining the accrued balances at the end of any reporting period. 
The principal considerations for our determination that performing procedures relating to accrued research and 
development costs is a critical audit matter are the significant judgment by management in determining the accrued costs 
which in turn led to a high degree of auditor judgment, subjectivity and effort in performing procedures and evaluating 
audit evidence for these accrued costs and the factors related to progress towards completion of the research and 
development activities, invoicing to date under the contracts, and communication from the research institution or other 
companies of any actual costs incurred during the period that have not yet been invoiced.
Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our 
overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls 
relating to accrued research and development costs, including controls over the review of contracts, accumulating 
information on actual costs incurred during the period, and assessment of progress towards completion of the research 
and development activities. These procedures also included, among others, (i) testing management’s process for 
estimating accrued research and development costs; (ii) evaluating the appropriateness of the method used by 
management to develop the estimates; (iii) evaluating the reasonableness of the factors used in determining the estimates 
related to progress towards completion of specific research and development activities and the associated cost incurred for 
services the Company has not yet been invoiced or otherwise notified of the actual cost at period end; and (iv) testing the 
completeness and accuracy of the underlying data including total costs included within executed contracts and actual 
billed expenses under these contracts.

SAGE THERAPEUTICS, INC. AND SUBSIDIARIES
Notes to Consolidated Financial Statements
1.
Nature of the Business
Sage Therapeutics, Inc. (“Sage” or the “Company”) is a biopharmaceutical company with a mission to pioneer 
solutions to deliver life-changing brain health medicines, so every person can thrive.
The Company’s product ZURZUVAE® (zuranolone) was approved by the U.S. Food and Drug Administration (the 
“FDA”) on August 4, 2023 for the treatment of postpartum depression (“PPD”) in adults. ZURZUVAE is a neuroactive 
steroid that is a positive allosteric modulator of GABAA receptors, targeting both synaptic and extrasynaptic GABAA 
receptors, and is the first oral, once-daily, 14-day treatment specifically indicated for adults with PPD. ZURZUVAE 
became commercially available for women with PPD in December 2023. 
The Company’s product ZULRESSO® (brexanolone) CIV injection is currently approved in the U.S. for the 
treatment of PPD in individuals 15 years old and older and was launched commercially in the U.S. in June 2019. 
ZULRESSO may only be administered in qualified, medically-supervised healthcare settings. The Company discontinued 
commercial availability of ZULRESSO in the U.S. as of December 31, 2024. The Company supported scheduled 
ZULRESSO infusions through the end of 2024. As a result of the decision to discontinue ZULRESSO commercial 
availability, during the year ended December 31, 2024, the Company incurred $5.4 million of incremental cost related to 
impairment of intangible assets, excess inventory write-off, prepaid and other current assets accelerated amortization, and 
accrued termination costs.
The Company has a portfolio of product candidates with a current focus on modulating two critical central nervous 
system (“CNS”) receptor systems, GABA and NMDA. The GABA receptor family, which is recognized as the major 
inhibitory neurotransmitter in the CNS, mediates downstream neurologic and bodily function via activation of GABAA 
receptors. The NMDA-type receptors of the glutamate receptor system are a major excitatory receptor system in the CNS. 
Dysfunction in these systems is implicated in a broad range of CNS disorders. The Company is targeting diseases and 
disorders of the brain across its pipeline.
In October 2024, the Company executed a plan to reorganize its business operations, including a reduction of 
approximately 33% of the Company’s total workforce and approximately 55% of the Company’s research and 
development workforce. See Note 14, Restructuring, for further details.
The Company was incorporated under the laws of the State of Delaware on April 16, 2010, and commenced 
operations on January 19, 2011 as Sterogen Biopharma, Inc. On September 13, 2011, the Company changed its name to 
Sage Therapeutics, Inc.
Risks and Uncertainties
The Company is subject to risks and uncertainties common to companies in the biopharmaceutical industry, 
including, but not limited to, the risks associated with developing product candidates at each stage of non-clinical and 
clinical development; the challenges associated with gaining regulatory approval of such product candidates; the risks 
associated with the marketing and sale of pharmaceutical products; the potential for development by third parties of new 
technological innovations that may compete with the Company’s products and product candidates; the dependence on key 
personnel; the challenges of protecting proprietary technology; the need to comply with government regulations; the high 
costs of drug development; the uncertainty of being able to secure additional capital when needed to fund operations; and 
the direct or indirect impacts of the macroeconomic environment and geopolitical events on its development activities, 
operations and financial condition.
The product candidates developed by the Company require approvals from the FDA or foreign regulatory authorities 
prior to commercial sales. There can be no assurance that the current and future product candidates of the Company will 
receive, or that ZURZUVAE will maintain, the necessary approvals. If the Company fails to successfully complete 
clinical development and generate results sufficient to file for regulatory approval or is denied approval or approval is 

F-8
delayed for any of its product candidates, such occurrences may have a material adverse impact on the Company’s 
business and its financial condition. 
The Company is also subject to additional risks and uncertainties arising from changes to the macroeconomic 
environment and geopolitical events. U.S. and global financial markets have experienced volatility and disruption due to 
macroeconomic and geopolitical events such as rising inflation, the risk of a recession and ongoing conflicts in other 
countries. In addition, if equity and credit markets deteriorate, it may make any future debt or equity financing more 
difficult to obtain on favorable terms, and potentially more dilutive to its existing stockholders. The Company cannot 
predict at this time to what extent it and its collaborators, employees, suppliers, contract manufacturers and/or vendors 
could potentially be negatively impacted by these events.
Going Concern
Under Accounting Standards Update (“ASU”) No. 2014-15, Presentation of Financial Statements—Going Concern 
(Subtopic 205-40), the Company has the responsibility to evaluate whether conditions and/or events raise substantial 
doubt about its ability to meet its future financial obligations as they become due within one year after the date that the 
financial statements are issued. The Company has incurred losses and negative cash flows from operations in each year 
since its inception, except for net income of $606.1 million for the year ended December 31, 2020, reflecting revenue 
recognized under a collaboration and license agreement with Biogen Inc. (“Biogen”) (the “Biogen Collaboration 
Agreement”). As of December 31, 2024, the Company had an accumulated deficit of $3.0 billion. Until such time, if ever, 
as the Company can generate substantial product revenue and/or collaboration revenue and achieve sustained profitability, 
the Company expects to finance its cash needs through a combination of equity offerings, debt financings, collaborations, 
strategic alliances, licensing arrangements and other sources of funding. If the Company is unable to raise additional funds 
through equity or debt financings or other sources of funding when needed, the Company may be required to delay, limit, 
reduce or terminate product development or future commercialization efforts or grant rights to develop and market 
products or product candidates that the Company would otherwise prefer to develop and market itself.
The Company expects that, based on its current operating plans, the Company’s existing cash, cash equivalents and 
marketable securities will be sufficient to fund its currently planned operations for at least the next 12 months from the 
filing date of these consolidated financial statements. At some point after that time, the Company anticipates it will 
require additional financing to fund its future operations. Even if the Company believes it has sufficient funds for its 
current or future operating plans, the Company may seek to raise additional capital if market conditions are favorable or in 
light of other strategic considerations.

Summary of Significant Accounting Policies
The following is a summary of significant accounting policies followed in the preparation of these consolidated 
financial statements.
Basis of Presentation
The accompanying consolidated financial statements include those of the Company and its subsidiaries after 
elimination of all intercompany accounts and transactions. The accompanying consolidated financial statements have been 
prepared in conformity with accounting principles generally accepted in the U.S. (“GAAP”).
Principles of Consolidation
The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. 
Intercompany accounts and transactions have been eliminated.
Use of Estimates 
The preparation of consolidated financial statements in conformity with GAAP requires management to make 
estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets 

F-9
and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses 
during the reporting period.
Cash Equivalents
The Company considers all highly liquid investments with an original maturity of 90 days or less to be cash 
equivalents. As of December 31, 2024, cash equivalents were comprised of money market funds, U.S. government 
securities, and U.S. commercial paper. As of December 31, 2023, cash equivalents were comprised of money market 
funds and U.S. government securities.
Marketable Securities
Marketable securities consist of investments with original maturities greater than 90 days. The Company has 
classified its investments with maturities beyond one year as short-term, based on their highly liquid nature and because 
such marketable securities represent the investment of cash that is available for current operations. The Company 
considers its investment portfolio of marketable securities to be available-for-sale. Accordingly, these investments are 
recorded at fair value, which is based on quoted market prices. Unrealized gains and losses are reported as the 
accumulated other comprehensive items in stockholders’ equity. When the fair value is below the amortized cost of the 
asset, an estimate of expected credit losses is made. The credit-related impairment amount is recognized in net income 
(loss); the remaining impairment amount and unrealized gains are reported as a component of accumulated other 
comprehensive items in stockholders’ equity. Credit losses are recognized through the use of an allowance for credit 
losses account and subsequent improvements in expected credit losses are recognized as a reversal of an amount in the 
allowance for credit losses account. If the Company has the intent to sell the security or it is more likely than not that the 
Company will be required to sell the security prior to recovery of its amortized cost basis, then the allowance for the credit 
loss is written-off and the excess of the amortized cost basis of the asset over its fair value is recorded in the consolidated 
statements of operations and comprehensive loss. Regardless of the Company’s intent to sell a security, it performs 
additional analysis on all securities with unrealized losses to evaluate losses associated with the creditworthiness of the 
security. Credit losses are identified where the Company does not expect to receive cash flows sufficient to recover the 
amortized cost basis of a security. The Company adjusts the cost of available-for-sale debt securities for amortization of 
premiums and accretion of discounts to maturity. Such amortization and accretion are included in interest income. The 
cost of securities sold is based on the specific identification method. The Company includes interest and dividends on 
securities classified as available-for-sale in interest income. 
Accounts Receivable
The Company’s trade accounts receivable consist of amounts due from specialty distributors and specialty 
pharmacies that have been certified under a Risk Evaluation and Mitigation Strategy program in the U.S. related to sales 
of ZULRESSO and have standard payment terms that generally require payment within 30 to 90 days from the invoice 
date. The Company monitors the financial performance and creditworthiness of customers so that it can properly assess 
and respond to changes in their credit profiles. The Company makes judgments as to its ability to collect outstanding 
receivables and provides an allowance for bad debts against the trade account receivables, when appropriate. As of 
December 31, 2024 and 2023, trade accounts receivable were $0.4 million and $1.4 million, respectively, and are included 
in prepaid expenses and other current assets on the consolidated balance sheets. As of December 31, 2024, the Company 
has not provided any allowance for bad debts against the trade accounts receivable.
Inventory
Prior to the initial date that regulatory approval is received for a product candidate of the Company, costs related to 
the production of inventory are recorded as research and development expense on the Company’s consolidated statements 
of operations and comprehensive loss in the period incurred.
Inventory is stated at the lower of cost or estimated net realizable value with cost determined on a first-in, first-out 
basis. Inventory costs may include purchases of raw materials, third-party contract manufacturing services, third-party 
packaging services, salary related expenses, overhead costs, and freight. Raw and intermediate materials that may be 
utilized for either research and development or commercial purposes, after approval of the product by the FDA, are 
classified as inventory. Amounts in inventory that are used for research and development purposes are charged to research 

F-10
and development expense when the product enters the research and development process and can no longer be used for 
commercial purposes and, therefore, does not have an “alternative future use” as defined in authoritative guidance. The 
Company performs an assessment of the recoverability of capitalized inventory during each reporting period and, if 
needed, writes down any excess and obsolete inventory to its estimated net realizable value in the period it is identified. If 
they occur, such impairment charges are recorded as a component of cost of revenues in the consolidated statements of 
operations and comprehensive loss. As of December 31, 2024, the Company did not have any capitalized inventory on 
hand. As of December 31, 2023, inventory was $1.5 million, and is included in prepaid expenses and other current assets 
on the consolidated balance sheets.
Property and Equipment
Property and equipment are recorded at cost and depreciated over their estimated useful lives using the straight-line 
method. Upon retirement or sale, the cost of assets disposed of and the related accumulated depreciation are removed 
from the accounts and any resulting gain or loss is credited or charged to the Company’s consolidated statements of 
operations and comprehensive loss. Repairs and maintenance costs are expensed as incurred.
Leases
The Company determines if an arrangement is a lease at contract inception. Operating lease assets represent the 
Company’s right to use an underlying asset for the lease term and operating lease liabilities represent the Company’s 
obligation to make payments arising from the lease. Operating lease assets and liabilities are recognized at the 
commencement date of the lease based upon the present value of lease payments over the lease term. When determining 
the lease term, the Company includes options to extend or terminate the lease when it is reasonably certain that the 
Company will exercise those options. The Company uses the Company’s incremental borrowing rate when the implicit 
interest rate is not readily determinable based upon the information available at the commencement date of the lease in 
determining the present value of the lease payments and the implicit interest rate when readily determinable.
The lease payments used to determine the Company’s operating lease assets may include lease incentives, stated rent 
increases and escalation clauses linked to rates of inflation, when determinable, and are recognized in the Company’s 
operating lease assets in the Company’s consolidated balance sheets. In addition, the Company’s contracts may contain 
lease and non-lease components. The Company combines lease and non-lease components, which are accounted for 
together as lease components.
The Company’s operating leases are reflected in the right-of-use operating asset; operating lease liability, current 
portion; and operating lease liability, net of current portion in the Company’s consolidated balance sheets. Lease expense 
for minimum lease payments is recognized on a straight-line basis over the lease term. Short-term leases, defined as leases 
that have a lease term of 12 months or less at the commencement date, are not recorded on the Company’s consolidated 
balance sheets and are recognized in the consolidated statements of operations and comprehensive loss on a straight-line 
basis over the term of the lease.
Variable lease payments are the amounts owed by the Company to a lessor that are not fixed, such as reimbursement 
for common area maintenance and utilities costs for facility leases. Variable lease payments are expensed when incurred.
Impairment of Long-Lived Assets
Long-lived assets consist of property and equipment and lease right-of-use assets. Long-lived assets to be held and 
used are tested for recoverability whenever events or changes in business circumstances indicate that the carrying amount 
of the assets may not be fully recoverable. Factors that the Company considers in deciding when to perform an 
impairment review include significant underperformance of the business in relation to expectations, significant negative 
industry or economic trends, and significant changes or planned changes in the use of the assets. If an impairment review 
is performed to evaluate a long-lived asset group for recoverability, the Company compares forecasts of undiscounted 
cash flows expected to result from the use and eventual disposition of the long-lived asset group to its carrying value. The 
impairment loss would be based on the excess of the carrying value of the impaired asset over its fair value, determined 
based on discounted cash flows. During the year ended December 31, 2024, the Company recorded $2.2 million of 
impairment losses on long-lived assets as a result of discontinuing the commercial availability of ZULRESSO. During the 
year ended December 31, 2023, the Company did not record any impairment losses on long-lived assets.

F-11
Cost of Revenues
Cost of revenues includes direct and indirect costs related to the manufacturing and distribution of ZULRESSO, 
including third-party contract manufacturing costs, packaging services, freight, third-party royalties payable on the 
Company’s net product revenue of ZULRESSO and amortization of intangible assets associated with ZULRESSO. Cost 
of revenues also includes our proportionate share of ZURZUVAE manufacturing costs under the Biogen Collaboration 
Agreement, (for additional information, refer to Note 7, Collaboration Agreements). Cost of revenues may also include 
period costs related to certain inventory manufacturing services and inventory adjustment charges. Prior to receiving FDA 
approval of ZULRESSO in March 2019 and ZURZUVAE in August 2023, the Company manufactured inventory in 
preparation for launch. As a result, certain manufacturing costs associated with revenues were expensed prior to FDA 
approval and, therefore, a portion of such costs are not included in cost of revenues during the years ended December 31, 
2024, 2023, and 2022.
Research and Development Costs and Accruals
Research and development expenses are comprised of costs incurred in performing research and development 
activities, including salaries and benefits, overhead costs, depreciation, contract services and other related costs. Research 
and development costs are expensed to operations as the related obligation is incurred. 
The Company has entered into various research and development contracts with research institutions and other 
companies both inside and outside of the U.S. These agreements are generally cancelable, and related costs are recorded 
as research and development expenses as incurred. The Company records accruals for estimated ongoing research and 
development costs. When billing terms under these contracts do not coincide with the timing of when the work is 
performed, the Company is required to make estimates of outstanding obligations to those third parties as of the end of the 
reporting period. Any accrual estimates are based on a number of factors, including the Company’s knowledge of the 
progress towards completion of the research and development activities, invoicing to date under the contracts, 
communication from the research institution or other companies of any actual costs incurred during the period that have 
not yet been invoiced, and the costs included in the contracts. Significant judgments and estimates are made in 
determining the accrued balances at the end of any reporting period. Actual results could differ from the estimates made 
by the Company. The historical accrual estimates made by the Company have not been materially different from the 
actual costs.
Stock-Based Compensation
The Company recognizes stock-based compensation expense for grants under our equity incentive plans and 
employee stock purchase plan. The Company accounts for all stock-based awards granted to employees at their fair value 
and recognize compensation expense over the vesting period of the award. Determining the amount of stock-based 
compensation to be recorded requires the Company to develop estimates of fair values of stock options as of the grant 
date. The Company calculates the grant date fair values of stock options using the Black-Scholes valuation model, which 
requires the input of subjective assumptions, including but not limited to expected stock price volatility over the term of 
the awards, the expected term of stock options and the expected forfeiture rate. The fair value of restricted stock awards 
granted to employees is based upon the quoted closing market price per share on the date of grant.
The Company has performance conditions included in certain of its performance restricted stock units that are based 
upon the achievement of pre-specified clinical development, regulatory, commercial and/or financial performance events. 
As the outcome of each event has inherent risk and uncertainties, and a positive outcome may not be known until the 
event is achieved, the Company begins to recognize the value of the performance-based restricted stock awards when the 
Company determines the achievement of each performance condition is deemed probable, a determination which requires 
significant judgment by management. At the probable date, the Company records estimated cumulative expense to date, 
with remaining expense amortized over the remaining service period until achievement has occurred.

F-12
Treasury Stock
The Company records treasury stock at cost. Treasury stock consists of shares of the Company’s common stock 
received from a then-employee as consideration for exercises of stock options.
Basic and Diluted Net Loss Per Share
Basic net loss per share is computed by dividing the net loss by the weighted average number of common shares 
outstanding for the period. For periods in which the Company has reported net losses, diluted net loss per share is the 
same as basic net loss per share, because dilutive common shares are not assumed to have been issued if their effect is 
antidilutive.
The Company reported a net loss for the years ended December 31, 2024, 2023 and 2022.
Concentration of Credit Risk and of Significant Suppliers
Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash, 
cash equivalents and marketable securities. The Company maintains accounts for all cash and cash equivalents at 
accredited financial institutions, and consequently, the Company believes that such funds are subject to minimal credit 
risk. The Company does not believe that it is subject to unusual credit risk beyond the normal credit risk associated with 
commercial banking relationships. The Company’s marketable securities, which primarily consist of U.S. government 
agency securities and treasuries, corporate bonds and commercial paper, potentially subject the Company to 
concentrations of credit risk. The Company has adopted an investment policy that limits the amounts the Company may 
invest in any one type of investment, defines allowable investments, and requires all investments held by the Company to 
minimum credit rating standards, thereby reducing credit risk exposure. The Company has no significant off-balance sheet 
concentrations of credit risk, such as foreign currency exchange contracts, option contracts, or other hedging 
arrangements.
The Company is dependent on third-party manufacturers to supply products for research and development activities 
for its programs. The Company also relies on and expects to continue to rely on third-party manufacturers to supply it 
with active pharmaceutical ingredients (“API”) and formulated drugs; and to provide other services related to 
manufacturing activities for these programs. These programs could be adversely affected by a significant interruption in 
the supply of API and formulated drugs, or the interruption of manufacturing related services.
Income Taxes
The Company accounts for income taxes under the asset and liability method. Under this method, deferred tax assets 
and liabilities are recognized for the estimated future tax consequences attributable to differences between financial 
statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and 
liabilities are measured using enacted rates in effect for the year in which these temporary differences are expected to be 
recovered or settled. Valuation allowances are provided if, based on the weight of available evidence, it is more likely 
than not that some or all of the deferred tax assets will not be realized.
The Company accounts for uncertain tax positions in accordance with the provisions of Accounting Standards 
Codification (“ASC”) Topic 740, “Income Taxes”. When uncertain tax positions exist, the Company recognizes the tax 
benefit of tax positions to the extent that the benefit will more likely than not be realized. The determination as to whether 
the tax benefit will more likely than not be realized is based upon the technical merits of the tax position as well as 
consideration of the available facts and circumstances. The Company accrues for potential interest and penalties related to 
unrecognized tax benefits in income tax expense.

F-13
Fair Value Measurements
Fair value is 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. Financial assets and liabilities carried at fair value are classified and 
disclosed in one of the following three categories:
Level 1 — Quoted market prices in active markets for identical assets or liabilities.
Level 2 — Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices 
in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for 
substantially the full term of the assets or liabilities.
Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value 
of the assets or liabilities.
The Company’s cash equivalents and marketable securities at December 31, 2024 and 2023 were carried at fair 
value, determined according to the fair value hierarchy; see Note 3, Fair Value Measurements.
The carrying amounts reflected in the consolidated balance sheets for the collaboration receivable – related party, 
accounts payable, and accrued expenses approximate their fair values due to their short-term maturities at December 31, 
2024 and 2023, respectively.
Comprehensive Income (Loss)
Comprehensive loss includes net loss and other changes in stockholders’ equity that result from transactions and 
economic events other than those with stockholders. The Company’s only element of other comprehensive income (loss) 
is unrealized gains and losses on marketable securities that are considered to be available-for-sale.
Revenue Recognition
Under ASC Topic 606, Revenue from Contracts with Customers (“Topic 606”), an entity recognizes revenue when 
or as performance obligations are satisfied by transferring control of promised goods or services to a customer, in an 
amount that reflects the consideration that the entity expects to receive in exchange for those goods or services. To 
determine revenue recognition for arrangements that an entity determines are within the scope of Topic 606, the entity 
performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in 
the contract; (iii) determine the transaction price, including variable consideration, if any; (iv) allocate the transaction 
price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a 
performance obligation. Arrangements that include rights to additional goods or services that are exercisable at a 
customer’s discretion are generally considered options. The Company assesses if these options provide a material right to 
the customer and if so, they are considered performance obligations. The exercise of a material right may be accounted for 
as a contract modification or as a continuation of the contract for accounting purposes. 
Topic 606 applies to all contracts with customers, except for contracts that are within the scope of other standards, 
such as collaboration arrangements.
For contracts determined to be within the scope of Topic 606, the Company assesses whether the goods or services 
promised within each contract are distinct to identify those that are performance obligations. This assessment involves 
subjective determinations and requires management to make judgments about the individual promised goods or services 
and whether such are separable from the other aspects of the contractual relationship. Promised goods and services are 
considered distinct provided that: (i) the customer can benefit from the good or service either on its own or together with 
other resources that are readily available to the customer and (ii) the entity’s promise to transfer the good or service to the 
customer is separately identifiable from other promises in the contract. 
The Company allocates the transaction price (the amount of consideration it expects to be entitled to from a 
customer in exchange for the promised goods or services) to each performance obligation and recognizes the associated 
revenue when (or as) each performance obligation is satisfied. The Company’s estimate of the transaction price for each 
contract includes all variable consideration to which the Company expects to be entitled.

F-14
Product Revenue, Net
Until the discontinuation of commercial availability of ZULRESSO as of December 31, 2024, the Company 
generated product revenue from the sale of ZULRESSO to a limited number of specialty distributors and specialty 
pharmacy providers in the U.S. The Company recognized product revenue, net of variable consideration related to certain 
allowances and accruals that are determined using the expected value method, in its consolidated financial statements at 
the point in time when control transfers to the customer, which was typically when the product has been delivered to the 
customer’s location. The amount included in the transaction price is constrained to the amount for which it is probable 
that a significant reversal of cumulative revenue recognized will not occur. The Company’s only performance obligation 
identified for ZULRESSO was to deliver the product to the location specified by the customer’s order.
The Company records shipping and handling costs associated with delivery of product to its customers within 
selling, general and administrative expenses on its consolidated statements of operations and comprehensive loss. The 
Company expenses incremental costs of obtaining a contract as incurred if the expected amortization period of the asset 
would be less than one year. If the Company were to incur incremental costs with an amortization period greater than a 
year, such costs would be capitalized as contract assets, as they are expected to be recovered, and would be expensed by 
amortizing on a systematic basis that is consistent with the transfer to the customer of the goods or services to which the 
asset relates. The Company did not have any contract assets (unbilled receivables) at December 31, 2024, as customer 
invoicing generally occurs before or at the time of revenue recognition. The Company did not have any contract liabilities 
at December 31, 2024, as the Company did not receive any payments in advance of satisfying its performance obligations 
to its customers. Amounts billed or invoiced that are considered trade accounts receivable are included in prepaid 
expenses and other current assets on the consolidated balance sheets.
As of December 31, 2024 and 2023, the Company had not provided any allowance for bad debts against the trade 
accounts receivable, and the amount of trade accounts receivable was not significant.
The Company records reserves, based on contractual terms, for the following components of variable consideration 
related to ZULRESSO sold by the Company during the reporting period, as well as its estimate of product that remains in 
the distribution channel inventory of its customers at the end of the reporting period. On a quarterly basis, the Company 
updates its estimates, if necessary, and records any material adjustments in the period they are identified.
Chargebacks: The Company estimates chargebacks from its customers who directly purchase the product from 
the Company for discounts resulting from contractual commitments to sell products to eligible healthcare settings 
at prices lower than the list prices charged to its customers. Customers charge the Company for the difference 
between what they pay to the Company for the product and the selling price to the eligible healthcare settings. 
Reserves for chargebacks consist of credits that the Company expects to issue for units that remain in the 
distribution channel inventories at the end of each reporting period that the Company expects will be sold to 
eligible healthcare settings, and chargebacks that customers have claimed, but for which the Company has not yet 
issued a credit.
Government Rebates: The Company is subject to discount obligations under government programs, including 
Medicaid. The Company records reserves for rebates in the same period the related product revenue is recognized, 
resulting in a reduction of ZULRESSO product revenue and a current liability that is included in accrued expenses 
on its consolidated balance sheets. The Company’s liability for these rebates consists of invoices received for 
claims from prior quarters that have not been paid or for which an invoice has not yet been received, estimates of 
claims for the current quarter, and estimates of future claims that will be made for product that has been 
recognized as revenue, but which remains in the distribution channel at the end of each reporting period.
Trade Discounts and Allowances: The Company generally provides customary invoice discounts on ZULRESSO 
sales to its customers for prompt payment and the Company pays fees for sales order management, data, and 
distribution services. The Company estimates its customers will earn these discounts and fees and deducts these 
discounts and fees in full from gross ZULRESSO revenue and accounts receivable at the time the Company 
recognizes the related revenue.

F-15
Financial Assistance: The Company provides voluntary financial assistance programs for ZULRESSO to patients 
with commercial insurance that have coverage and reside in states that allow financial assistance. The Company 
estimates the financial assistance amounts for ZULRESSO and records any such amounts within accrued 
expenses on its consolidated balance sheets. The calculation of the accrual for financial assistance is based on an 
estimate of claims and the cost per claim that the Company expects to receive using demographics for patients 
who have registered and been approved for assistance. Any adjustments are recorded in the same period the 
related revenue is recognized, resulting in a reduction of product revenue and the establishment of a current 
liability, which is included as a component of accrued expenses on the consolidated balance sheets.
Product Returns: Consistent with industry practice, the Company offers product return rights with respect to 
ZULRESSO to customers for damaged, defective or expiring product, provided it is within a specified period 
around the product expiration date as set forth in the Company’s return goods policy. The Company estimates the 
amount of its product sales that may be returned by its customers and records this estimate as a reduction of 
revenue in the period the related product revenue is recognized, as well as a reserve within accrued expenses on 
the consolidated balance sheets. Product returns have not been significant to date and are not expected to be 
significant in the future.
License, Milestone, and Collaboration Revenue
In assessing whether a promised good or service is distinct in the evaluation of a collaboration or license 
arrangement subject to Topic 606, the Company considers factors such as the research, manufacturing and 
commercialization capabilities of the collaboration partner and the availability of the associated expertise in the general 
marketplace. The Company also considers the intended benefit of the contract in assessing whether a promised good or 
service is separately identifiable from other promises in the contract. If a promised good or service is not distinct, the 
Company is required to combine that good or service with other promised goods or services until it identifies a bundle of 
goods or services that is distinct.
The transaction price is then determined and allocated to the identified performance obligations in proportion to their 
standalone selling prices (“SSP”) on a relative SSP basis. SSP is determined at contract inception and is not updated to 
reflect changes between contract inception and when the performance obligations are satisfied. Determining the SSP for 
performance obligations requires significant judgment. In developing the SSP for a performance obligation, the Company 
considers applicable market conditions and relevant entity-specific factors, including factors that were contemplated in 
negotiating the agreement with the customer and estimated costs. In certain circumstances, the Company may apply the 
residual method to determine the SSP of a good or service if the SSP is considered highly variable or uncertain. The 
Company validates the SSP for performance obligations by evaluating whether changes in the key assumptions used to 
determine the SSP will have a significant effect on the allocation of arrangement consideration between multiple 
performance obligations.
If the consideration promised in a contract includes a variable amount, the Company estimates the amount of 
consideration to which it will be entitled in exchange for transferring the promised goods or services to a customer. The 
Company determines the amount of variable consideration by using the expected value method or the most likely amount 
method. The Company includes the unconstrained amount of estimated variable consideration in the transaction price. The 
amount included in the transaction price is constrained to the amount for which it is probable that a significant reversal of 
cumulative revenue recognized will not occur. At the end of each subsequent reporting period, the Company re-evaluates 
the estimated variable consideration included in the transaction price and any related constraint, and if necessary, adjusts 
its estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis in the 
period of adjustment.
If an arrangement includes development and regulatory milestone payments, the Company evaluates whether the 
milestones are considered probable of being reached and estimates the amount to be included in the transaction price 
using the most likely amount method. If it is probable that a significant revenue reversal would not occur, the associated 
milestone value is included in the transaction price. Milestone payments that are not within the Company’s control or the 
licensee’s control, such as regulatory approvals, are generally not considered probable of being achieved until those 
approvals are received.

F-16
In determining the transaction price, the Company adjusts consideration for the effects of the time value of money if 
the timing of payments provides the Company with a significant benefit of financing. The Company does not assess 
whether a contract has a significant financing component if the expectation at contract inception is such that the period 
between payment by the licensees and the transfer of the promised goods or services to the licensees will be one year or 
less. The Company assessed its arrangements with Shionogi & Co., Ltd. (“Shionogi”) and Biogen and concluded that a 
significant financing component does not exist for either arrangement. For arrangements with licenses of intellectual 
property that include sales-based royalties or milestone payments based on the level of sales, and the license is deemed to 
be the predominant item to which the royalties or milestone payments relate, the Company recognizes royalty revenue and 
sales-based milestones at the later of (i) when the related sales occur, or (ii) when the performance obligation to which the 
royalty or milestone payment has been allocated has been satisfied.
The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective 
performance obligation when (or as) each performance obligation is satisfied at a point in time or over time, and if over 
time this is based on the use of an output or input method. Revenue from the Company’s collaboration agreement with 
Shionogi has come from initial, upfront consideration upon execution of the agreement and for the supply of drug product 
for Shionogi’s clinical trials. Revenue from the Company’s collaboration agreement with Biogen has come from initial, 
upfront consideration related to the execution of the Biogen Collaboration Agreement, milestone payments and the 
Company’s share of ZURZUVAE revenues under the elements of the arrangement accounted for under ASC Topic 808, 
Collaborative Arrangements (“Topic 808”). For additional information, see the Collaborative Arrangements section 
below and refer to Note 7, Collaboration Agreements.
Collaborative Arrangements
The Company analyzes its collaboration arrangements to assess whether such arrangements involve joint operating 
activities performed by parties that are both active participants in the activities and exposed to significant risks and 
rewards dependent on the commercial success of such activities and therefore within the scope of Topic 808. This 
assessment is performed throughout the life of the arrangement based on changes in the responsibilities of all parties in the 
arrangement. For collaboration arrangements within the scope of Topic 808 that contain multiple elements, the Company 
first determines which elements of the collaboration are deemed to be within the scope of Topic 808 and which elements 
of the collaboration are more reflective of a vendor-customer relationship and therefore within the scope of Topic 606. For 
elements of collaboration arrangements that are accounted for pursuant to Topic 808, an appropriate recognition method is 
determined and applied consistently, either by analogy to authoritative accounting literature or by applying a reasonable 
and rational policy election. For those elements of the arrangement that are accounted for pursuant to Topic 606, the 
Company applies the five-step model described above and presents the arrangement as license and milestone revenue or 
other collaboration revenue in the consolidated statements of operations and comprehensive loss.
For collaboration arrangements that are within the scope of Topic 808, the Company evaluates the income statement 
classification for presentation of amounts due from or owed to other participants associated with multiple activities in a 
collaboration arrangement based on the nature of each separate activity. Payments or reimbursements that are the result of 
a collaborative relationship instead of a vendor-customer relationship are recorded as an increase to collaboration revenue, 
an increase to or reduction of cost of revenues, research and development expense or selling, general and administrative 
expense, depending on the nature of the activity. For additional information relating to the accounting for the co-
commercialization of ZURZUVAE in the U.S. with Biogen under Topic 808, refer to Note 7, Collaboration Agreements.
Recently Adopted Accounting Pronouncements
In November 2023, the Financial Accounting Standards Board (“FASB”) issued ASU 2023-07, Segment Reporting 
(Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”). ASU 2023-07 requires disclosure of 
incremental segment information on an annual and interim basis. The amendments also require companies with a single 
reportable segment to provide all disclosures required by this amendment and all existing segment disclosures in ASC 
280, Segment Reporting. The amendments are effective for fiscal years beginning after December 15, 2023, and interim 
periods beginning after December 15, 2024. The Company adopted ASU 2023-07, effective December 31, 2024, in these 
consolidated financial statements. ASU 2023-07 only impacted the disclosures and did not impact the consolidated 
financial statements. See Note 15, Segment Information, for disclosures related to the adoption of ASU 2023-07.

F-17
Recently Issued Accounting Pronouncements
In December 2023, FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax 
Disclosures (“ASU 2023-09”). ASU 2023-09 modifies the rules on income tax disclosures to enhance the transparency 
and decision-usefulness of income tax disclosures, particularly in the rate reconciliation table and disclosures about 
income taxes paid. The amendments are intended to address investors’ requests for income tax disclosures that provide 
more information to help them better understand an entity’s exposure to potential changes in tax laws and the ensuing 
risks and opportunities and to assess income tax information that affects cash flow forecasts and capital allocation 
decisions. The guidance also eliminates certain existing disclosure requirements related to uncertain tax positions and 
unrecognized deferred tax liabilities. The guidance is effective for all entities for annual periods beginning after December 
15, 2025. All entities should apply the guidance prospectively but have the option to apply it retrospectively. Early 
adoption is permitted. The Company is continuing to assess the timing of adoption and the potential impacts of ASU 
2023-09 on the consolidated financial statements and related disclosures.
In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - 
Expense Disaggregation Disclosures (Subtopic 220-40) (“ASU 2024-03”). ASU 2024-03 modifies the rules on income 
statement disclosures to enhance the transparency of and include more detailed information about the types of expenses, 
including purchases of inventory, employee compensation, depreciation, amortization, and depletion, in commonly 
presented expense captions such as cost of sales, research and development, and selling, general and administrative 
expenses. The amendments are intended to address investors’ requests for income statement expense disclosures that 
provide more information to help them better understand the components of an entity’s expenses, make their own 
judgments about the entity’s performance, and more accurately forecast expenses, and enable investors to better assess an 
entity’s prospects for future cash flows. It will also provide contextual information for an entity’s presentation and 
consideration of management’s discussion and analysis of financial position and results of operations. The guidance is 
effective for all entities for annual periods beginning after December 15, 2026. All entities should apply the guidance 
prospectively but have the option to apply it retrospectively. Early adoption is permitted. The Company is continuing to 
assess the timing of adoption and the potential impacts of ASU 2024-03 on the consolidated financial statements and 
related disclosures.

The Company’s cash equivalents are classified within Level 1 and Level 2 of the fair value hierarchy. The 
Company’s investments in marketable securities are classified within Level 2 of the fair value hierarchy.
The fair values of the Company’s marketable securities are based on prices obtained from independent pricing 
sources. Consistent with the fair value hierarchy described in Note 2, Summary of Significant Accounting Policies, 
marketable securities with validated quotes from pricing services are reflected within Level 2, as they are primarily based 
on observable pricing for similar assets or other market observable inputs. Typical inputs used by these pricing services 
include, but are not limited to, reported trades, benchmark yields, issuer spreads, bids, offers or estimates of cash flow, 
prepayment spreads and default rates. The Company performs validation procedures to ensure the reasonableness of this 
data. The Company performs its own review of prices received from the independent pricing services by comparing these 
prices to other sources. After completing the validation procedures, the Company did not adjust or override any fair value 
measurements provided by the pricing services as of December 31, 2024 and 2023.

interest receivable relating to the Company’s available-for-sale securities which is included within prepaid expenses and 
other current assets in the accompanying consolidated balance sheets. No accrued interest receivable was written off 
during years ended December 31, 2024, 2023, and 2022. Realized gains or losses were immaterial for the years ended

As of December 31, 2024 and 2023, the unrealized losses on the Company’s investments in U.S. government 
securities, U.S. corporate bonds, international corporate bonds, and U.S. municipal securities were caused by interest rate 
increases. The Company purchased those investments at a premium relative to their face amount. The current credit 
ratings are all within the guidelines of the investment policy of the Company and the Company does not expect the issuers 
to settle any security at a price less than the amortized cost basis of the investment. The Company does not intend to sell 
the investments and it is not probable that the Company will be required to sell the investments before recovery of their 
amortized cost basis.
As of December 31, 2024, all marketable securities held by the Company had remaining contractual maturities of 
one year or less, except for U.S. corporate bonds and international corporate bonds with a fair value of $30.7 million that 
had maturities of one to two years.
As of December 31, 2023, all marketable securities held by the Company had remaining contractual maturities of 
one year or less, except for U.S. government securities, U.S. corporate bonds, international corporate bonds and municipal 
securities with a fair value of $110.3 million that had maturities of one to two years.
All marketable securities, including those with remaining contractual maturities of more than one year, are classified 
as current assets on the balance sheet because they are considered to be “available-for-sale” and the Company can convert 
them into cash to fund current operations.
There have been no impairments of the Company’s assets measured and carried at fair value during the years ended 
December 31, 2024 and 2023.

respectively, of accrued expenses related to canceling excess purchase commitments for manufacturing as a result of the 
complete response letter (“CRL”) received in August 2023 from the FDA related to the New Drug Application (“NDA”) 
for zuranolone for the treatment of major depressive disorder (“MDD”). During the year ended December 31, 2023, $28.9 
million of expenses related to the cancelation of excess purchase commitments were recorded as research and 
development expense in the consolidated statements of operations and comprehensive loss, net of amounts subject to 
reimbursement under the Biogen Collaboration Agreement of $14.5 million.
6.     Leases, Commitments and Contingencies
Operating Leases
The Company leases office space and certain equipment. All of the leases recorded on the consolidated balance 
sheets are operating leases. The Company’s leases have remaining lease terms ranging from less than one year to 
approximately five years. Some of the leases include options to extend the leases for up to five years. These options were 
not included for the purpose of determining the right-of-use assets and associated lease liabilities as the Company 
determined that the renewal of these leases is not reasonably certain so only the original lease term was taken into 
consideration. The leases do not include any restrictions or covenants that had to be accounted for under the lease 
guidance.
During the fiscal years ended December 31, 2024, 2023, and 2022, the Company leased office space in three multi-
tenant buildings in Cambridge, Massachusetts, consisting of 63,017 square feet in the first building, under an operating 
lease that expired on August 31, 2024; 40,419 square feet in the second building, under an operating lease that expired on 
August 31, 2024; and 30,567 square feet in the third building, under an operating lease that commenced in August 2024 
that will expire on February 28, 2030; and in a multi-tenant building in Raleigh, North Carolina, consisting of 15,525 
square feet under an operating lease that expired on November 30, 2024.
In January 2024, the Company entered into the lease agreement (the “New Lease”) for office space in a multi-
tenant building in Cambridge, Massachusetts (the “New Premises”). The accounting lease commencement in accordance 
with ASC 842, Leases, occurred on August 2, 2024, and the Company recorded a total associated right-of-use asset of 
$11.6 million and the corresponding lease liability of $10.0 million. This includes a reclassification of $1.5 million from 
prepaid expenses and other current assets to right-of-use asset related to build out costs which were determined to be 
owned by the lessor. The contractual term of the New Lease commenced on September 1, 2024 (the “Term 
Commencement Date”), which is the date the Company relocated its headquarters to the New Premises. The Company’s 

F-22
obligation for the payment of rent for the New Premises begins six months after the Term Commencement Date (the 
“Rent Commencement Date”). The New Lease has an initial term of approximately sixty-six months, measured from the 
Term Commencement Date (the “New Lease Term”). The Company has the option to extend the New Lease one time for 
an additional five-year period, subject to the terms therein; however, the exercise of the option to extend the lease term 
was not determined to be reasonably certain, and the Company will therefore recognize lease expense through the 
expiration of the New Lease Term in February 2030.
In connection with its entry into the New Lease, and as a security deposit, the Company has provided the 
Landlord a letter of credit in the amount of approximately $1.4 million, classified within long-term restricted cash on the 
consolidated balance sheets, which the Company and the Landlord have agreed may be reduced to approximately 
$1.2 million following the third anniversary of the Rent Commencement Date, provided that no event of default by the 
Company has occurred. The Landlord has the right to terminate the New Lease upon customary events of default.
During the year ended December 31, 2021, the Company entered into a sublease for a portion of the leased office 
space in the second multi-tenant building in Cambridge, Massachusetts, which was terminated effective April 5, 2024.

The Company made an accounting policy election not to apply the recognition requirements to short-term leases. 
The Company recognizes the lease payments for short-term leases as expense on a straight-line basis over the lease term, 
and variable lease payments in the period in which the obligation for those payments is incurred.

The interest rate implicit in lease contracts is typically not readily determinable and as such, the Company uses its 
incremental borrowing rate based on the information available at the lease commencement date, which represents an 
internally developed rate that would be incurred to borrow, on a collateralized basis, over a similar term, an amount equal 
to the lease payments in a similar economic environment.

Legal Proceedings
On August 28, 2024, named plaintiff Darren Korver filed a purported federal securities class action lawsuit in the 
Southern District of New York against the Company and individuals, Barry E. Greene and Kimi Iguchi (the “Securities 
Class Action”). The complaint in the Securities Class Action alleges violations of U.S. securities laws under Sections 
10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder and seeks an as-yet 
unspecified amount of damages allegedly sustained by parties who purchased Sage stock between April 12, 2021 and July 
23, 2024, as well as applicable attorneys’ fees and costs. The Company denies any allegations of wrongdoing and intends 
to vigorously defend against the Securities Class Action. 
On October 16, 2024, the Company received a subpoena from the Enforcement Division of the SEC requesting 
documents and information related to the Company’s NDA for zuranolone for the treatment of MDD, including 
communications with the FDA and any communications containing material nonpublic information. The Company is 
cooperating with the SEC and intends to continue to provide information responsive to the SEC’s requests. 

F-24
At this time, the Company is unable to predict the outcome of the Securities Class Action or the SEC 
investigation or reasonably estimate a range of possible losses.
On January 16, 2025, the Company commenced litigation against Biogen in the Delaware Court of Chancery 
seeking declaratory, injunctive and other relief. In its complaint, the Company alleges that Biogen breached the standstill 
provision in the stock purchase agreement it entered into with Biogen on November 27, 2020 (the “Biogen Stock Purchase 
Agreement”), by making an unsolicited acquisition proposal and related public disclosures. On this basis, the Company 
also sought a temporary restraining order enjoining Biogen from future breaches of the standstill provision. At a hearing 
held on January 28, 2025, the Court granted the Company’s motion for a temporary restraining order against Biogen MA 
Inc., and entered an implementing order on January 30, 2025 (the “TRO Order”). Pursuant to the TRO Order, unless 
consented to by the Company in writing or otherwise ordered by the court, Biogen MA Inc. and its directors, officers, 
agents, employees, attorneys, representatives, persons in active concert or participation with it, and anyone acting under 
its direction or control are enjoined from taking any action inconsistent with the Biogen Stock Purchase Agreement’s 
contractual prohibitions against (i) making a public acquisition proposal, (ii) making a private acquisition proposal that is 
reasonably expected to require public disclosure, or (iii) publicly encouraging any acquisition proposal. Various motions 
and related items (whether procedural, discovery-related and/or substantive in nature) occur from time to time with 
respect to this matter.  The Company intends to continue to vigorously pursue its claims against Biogen, but the Company 
is unable to predict the outcome of the litigation at this time.
7.     Collaboration Agreements
Shionogi
In June 2018, the Company entered into a strategic collaboration with Shionogi for the clinical development and 
commercialization of zuranolone for the treatment of MDD and other potential indications in Japan, Taiwan and South 
Korea (the “Shionogi Territory”). In October 2018, the Company entered into a supply agreement with Shionogi for the 
Company to supply zuranolone clinical material to Shionogi.
Under the terms of the collaboration and license agreement, Shionogi is responsible for all clinical development and 
regulatory filings for zuranolone in MDD and other indications in the Shionogi Territory and would be responsible for 
commercialization of zuranolone in the Shionogi Territory, if zuranolone is successfully developed and obtains marketing 
approval in any of the countries within the Shionogi Territory. Shionogi was required to make an upfront payment to the 
Company of $90.0 million, and the Company was originally eligible to receive additional payments of up to $485.0 
million if certain regulatory and commercial milestones are achieved by Shionogi. The potential future milestone 
payments originally included up to $70.0 million for the achievement of specified regulatory milestones, up to $30.0 
million for the achievement of specified commercialization milestones, and up to $385.0 million for the achievement of 
specified net sales milestones. The potential future milestone payments for achievement of specified regulatory milestones 
was reduced to $55.0 million upon failure to received FDA approval of zuranolone for the treatment of MDD in the U.S. 
prior to December 31, 2023. The Company is eligible to receive tiered royalties on sales of zuranolone in the Shionogi 
Territory, if development efforts are successful, with tiers averaging in the low to mid-twenty percent range, subject to 
other terms of the agreement. As between the Company and Shionogi, the Company maintains exclusive rights to develop 
and commercialize zuranolone outside of the Shionogi Territory. The upfront cash payment and any payments for 
milestones and royalties are non-refundable and non-creditable. Due to the uncertainty of pharmaceutical development 
and the high historical failure rates generally associated with drug development, the Company may not receive any 
milestone payments or any royalty payments from Shionogi.
The Company concluded that Shionogi meets the definition of a customer because the Company is delivering 
intellectual property and know-how rights for the zuranolone program in support of territories in which the parties are not 
jointly sharing the risks and rewards. In addition, the Company determined that the Shionogi collaboration met the 
requirements to be accounted for as a contract, including that it is probable that the Company will collect the 
consideration to which the Company is entitled in exchange for the goods or services that will be delivered to Shionogi.
The Company determined that the performance obligations in the Shionogi collaboration agreement included the 
license to zuranolone and the supply of certain materials during the clinical development phase, which includes the supply 

F-25
of API. The performance obligation related to the license to zuranolone was determined to be distinct from other 
performance obligations and therefore was a separate performance obligation for which control was transferred upon 
signing. The obligation to provide certain clinical materials, including API for use during the development period, was 
determined to be a separate performance obligation. Given that Shionogi is not obligated to purchase any minimum 
amount or quantities of commercial API, the supply of API to Shionogi for commercial use was determined to be an 
option for Shionogi, rather than a performance obligation of the Company at contract inception and will be accounted for 
if and when exercised. The Company also determined that there was no separate material right in connection with the 
supply of API for commercial use as the expected pricing was not at a discount. Given this fact pattern, the Company has 
concluded the agreement has two performance obligations. 
Under the clinical supply agreement, the Company is obligated to manufacture and supply to Shionogi (i) clinical 
quantities of API reasonably required by Shionogi for the development of licensed products in the Shionogi Territory 
under the collaboration and license agreement and (ii) quantities of drug product reasonably required for use by Shionogi 
in Phase 1 clinical trials of zuranolone in the Shionogi Territory under the collaboration and license agreement, in the 
quantities agreed to by the parties. Collaboration revenue from the clinical supply agreement, which excludes the $90.0 
million upfront payment, pertains to the clinical material sold under the terms of the clinical supply agreement. The 
Company records the costs related to the clinical supply agreement in research and development expense on its 
consolidated statements of operations and comprehensive loss. During the years ended December 31, 2024 and 2023, $0.6 
million and $0.2 million, respectively, of collaboration revenue was recognized from the Company’s agreement with 
Shionogi. During the year ended December 31, 2022, no collaboration revenue was recognized from the Company’s 
agreement with Shionogi.
The Company completed the evaluation of the SSP of each of the performance obligations and determined that the 
SSP of the license performance obligation was $90.0 million. The Company recognized the transaction price allocated to 
the license performance obligation of $90.0 million as revenue during the quarter upon delivery of the license to Shionogi 
and resulting ability of Shionogi to use and benefit from the license, which was in the three months ended June 30, 2018. 
The remaining transaction price related to the performance obligation for the supply of certain clinical material is not 
significant. The potential milestone payments that the Company is eligible to receive were excluded from the transaction 
price, as all milestone amounts were fully constrained based on the probability of achievement. The Company will re-
evaluate the transaction price at the end of each reporting period and as uncertain events are resolved or other changes in 
circumstances occur, and, if necessary, adjust its estimate of the transaction price.
Biogen
In November 2020, the Company entered into the Biogen Collaboration Agreement to jointly develop and 
commercialize SAGE-217 products and SAGE-324 products. Concurrently, the Company also entered into the Biogen 
Stock Purchase Agreement, under which BIMA purchased shares of the Company’s common stock. The Biogen 
Collaboration Agreement became effective on December 28, 2020 (the “Effective Date”). 
Under the terms of the Biogen Collaboration Agreement, the Company granted Biogen co-exclusive licenses to 
develop and commercialize SAGE-217 products and SAGE-324 products (each, a “Product Class” and together, the 
“Licensed Products”) in the U.S., an exclusive license to develop and commercialize SAGE-217 products in all countries 
of the world other than the U.S. and the Shionogi Territory, and an exclusive license to develop and commercialize 
SAGE-324 products in all countries of the world other than the U.S. The Company refers to the territories outside the U.S. 
to which Biogen has rights under the Biogen Collaboration Agreement with respect to the applicable Licensed Product as 
the “Biogen Territory”.
In September 2024, Biogen notified the Company of its termination of the Biogen Collaboration Agreement solely 
with respect to products containing the Company’s SAGE-324 products on a worldwide basis, effective February 17, 
2025 (the “SAGE-324 Termination”), in accordance with the required notice period. As a result of the SAGE-324 
Termination, as of February 17, 2025 (the “SAGE-324 Termination effective date”), all licenses granted by the Company 
to Biogen or by Biogen to the Company regarding the SAGE-324 products shall expire with respect to the SAGE-324 
products on a worldwide basis. Biogen shall grant to the Company an irrevocable, perpetual license for any Biogen 
background technology, Biogen collaboration technology or joint collaboration technology that exists as of February 17, 

F-26
2025 with respect to the SAGE-324 products, in each case in accordance with the terms of the Biogen Collaboration 
Agreement.
In connection with the effectiveness of the Biogen Collaboration Agreement and the closing of the sale of shares to 
BIMA in December 2020, the Company received $1.5 billion in consideration, comprised of an upfront payment of 
$875.0 million and the $650.0 million purchase price for 6,241,473 newly issued shares of the Company’s common stock 
(the “Biogen Shares”). As a result of the purchase of the Biogen Shares, Biogen is a related party of the Company.
The Company was initially eligible to receive additional payments of up to $1.6 billion from Biogen if certain 
regulatory and commercial milestones were achieved. The potential future milestone payments for SAGE-217 products 
included up to $475.0 million for the achievement of specified regulatory and commercial milestones, including a 
milestone payment of $75.0 million for the first commercial sale of ZURZUVAE for the treatment of women with PPD in 
the U.S. and, if approved, a milestone payment of $150.0 million for the first commercial sale of ZURZUVAE for the 
treatment of MDD in the U.S., and up to $300.0 million for the achievement of specified net sales milestones. In the 
fourth quarter of 2023, the Company achieved the $75.0 million milestone for the first commercial sale of ZURZUVAE 
for the treatment of women with PPD in the U.S. Because the Company and Biogen have agreed not to pursue further 
development of zuranolone for the treatment of MDD in the U.S., the Company will not receive the $150.0 million 
milestone payment for the first commercial sale of ZURZUVAE for the treatment of MDD in the U.S.
The potential future milestone payments for SAGE-324 products initially included up to $520.0 million for the 
achievement of specified regulatory and commercial milestones and up to $300.0 million for the achievement of specified 
net sales milestones. As a result of the SAGE-324 Termination, the Company will not receive any milestone payments for 
SAGE-324 products under the Biogen Collaboration Agreement. 
The Company is also eligible to receive tiered royalties on net sales of SAGE-217 products in the Biogen Territory 
at percentage rates ranging from the high teens to low twenties.
Due to the uncertainty of pharmaceutical development and the high historical failure rates generally associated with 
drug development, and the challenges of launching and commercializing a product, if approved, the Company may never 
receive any additional milestone payments or any royalty payments under the Biogen Collaboration Agreement.
Development and commercialization activities in the U.S. under the Biogen Collaboration Agreement are conducted 
pursuant to plans agreed to by the Company and Biogen and overseen by a joint steering committee that consists of an 
equal number of representatives of each party. The Company and Biogen share equally in the costs for development and 
commercialization, as well as the profits and losses upon FDA approval and commencement of product sales, in the U.S., 
subject to the Company’s opt-out right described below. Biogen is solely responsible for all development activities and 
costs related to any development and commercialization of SAGE-217 products and, prior to the SAGE-324 Termination, 
SAGE-324 products, for the Biogen Territory, and the Company will receive royalties on any sales in the Biogen 
Territory, as mentioned above. Biogen is the principal and records sales of SAGE-217 products globally.
The Company is obligated to supply API and bulk drug product for the Biogen Territory and API, bulk drug product 
and final drug product for the U.S. to support development and commercialization activities. Biogen has the right to 
assume manufacturing responsibilities for API for the Biogen Territory at any time during the term of the agreement, and 
the agreement further provides that Biogen will, within a reasonable period of time after the Effective Date, assume 
manufacturing responsibility for bulk drug product for the Biogen Territory.
Unless terminated earlier, the Biogen Collaboration Agreement will continue on a Licensed Product-by-Licensed 
Product and country-by-country basis until the date on which (a) in any country in the Biogen Territory, the royalty term 
has expired for all Licensed Products in a Product Class in such country, and (b) for the U.S., the parties agree to 
permanently cease to commercialize all Licensed Products in a Product Class. Biogen also has the right to terminate the 
Biogen Collaboration Agreement for convenience in its entirety, on a Product Class-by-Product Class basis (such as the 
SAGE-324 Termination) or as to a particular region, upon advance written notice. The Company has an opt-out right to 
convert the co-exclusive licenses in the U.S. to an exclusive license to Biogen on a Product Class-by-Product Class basis. 
Following the exercise of the opt-out right, the Company would no longer share equally in the profits and losses in the 

F-27
U.S. and would be entitled to receive certain royalty payments at percentage rates ranging from the high teens to low 
twenties and additional sales milestones.
The Company concluded that the Biogen Collaboration Agreement and the Biogen Stock Purchase Agreement 
should be combined and treated as a single arrangement for accounting purposes as the agreements were entered into 
contemporaneously and in contemplation of one another. The Company determined that the combined agreements had 
elements that were within the scope of Topic 606 and Topic 808.
As of the Effective Date, the Company identified the following promises in the Biogen Collaboration Agreement 
that were evaluated under the scope of Topic 606: delivery of (i) a co-exclusive license for SAGE-217 products in the 
U.S.; (ii) an exclusive license for SAGE-217 products in the Biogen Territory; (iii) a co-exclusive license for SAGE-324 
products in the U.S.; (iv) an exclusive license for SAGE-324 products in the Biogen Territory; (v) the clinical 
manufacturing supply of API and bulk drug product for SAGE-217 products in the Biogen Territory; and (vi) the clinical 
manufacturing supply of API and bulk drug product for SAGE-324 products in the Biogen Territory.
The Company also evaluated whether certain options outlined within the Biogen Collaboration Agreement 
represented material rights that would give rise to a performance obligation and concluded that none of the options convey 
a material right to Biogen and therefore are not considered separate performance obligations within the Biogen 
Collaboration Agreement.
The Company assessed the above promises at contract inception and determined that the co-exclusive licenses for 
SAGE-217 products and SAGE-324 products in the U.S. are reflective of a vendor-customer relationship and therefore 
represent performance obligations within the scope of Topic 606. The co-exclusive license for SAGE-217 products and 
SAGE-324 products in the U.S. are considered functional intellectual property and distinct from other promises under the 
contract. The exclusive licenses for SAGE-217 products and SAGE-324 products in the Biogen Territory are considered 
functional licenses that are distinct in the context of the Biogen Collaboration Agreement as Biogen can benefit from the 
licenses on its own or together with other readily available resources. As the co-exclusive licenses in the U.S. and the 
exclusive licenses in the Biogen Territory are delivered at the same time, they are considered one performance obligation 
at contract inception. The clinical manufacturing supply of API and bulk drug product for SAGE-217 products and 
SAGE-324 products for the Biogen Territory are considered distinct in the context of the Biogen Collaboration 
Agreement as Biogen can benefit from the manufacturing services together with the licenses transferred by the Company 
at the inception of the agreement. Therefore, each represents a separate performance obligation within a contract with a 
customer under the scope of Topic 606 at contract inception.
The Company determined the transaction price under Topic 606 at the inception of the Biogen Collaboration 
Agreement to be $1.1 billion, consisting of the upfront payment of $875.0 million plus $232.5 million in excess proceeds 
from the equity investment under the Biogen Stock Purchase Agreement, when measured at fair value, plus future variable 
consideration for manufacturing supply of clinical API and bulk drug product for the Biogen Territory. The amount of 
variable consideration related to the future manufacturing services was not material. At inception, the Company 
determined that any variable consideration related to clinical development and regulatory or commercial milestones is 
deemed to be fully constrained and therefore excluded from the transaction price due to the high degree of uncertainty and 
risk associated with these potential payments, as the Company determined that it could not assert that it was probable that 
a significant reversal in the amount of cumulative revenue recognized will not occur. The Company also determined that 
royalties and sales milestones relate solely to the licenses of intellectual property and are therefore excluded from the 
transaction price under the sales- or usage-based royalty exception of Topic 606. Revenue related to these royalties and 
sales milestones will only be recognized when the associated sales occur, and relevant thresholds are met. As such, the 
entirety of the $1.1 billion transaction price was allocated to the transfer of the co-exclusive licenses for SAGE-217 
products and SAGE-324 products in the U.S. and the exclusive licenses for SAGE-217 products and SAGE-324 products 
in the Biogen Territory and was recognized as license revenue during the year ended December 31, 2020. 
In the fourth quarter of 2023, the Company achieved a milestone for the first commercial sale of ZURZUVAE for 
the treatment of women with PPD in the U.S. and recognized license and milestone revenue – related party of $75.0 
million during the fourth quarter of the year ended December 31, 2023. Payment of the $75.0 million milestone was 

F-28
received in January 2024. During the years ended December 31, 2024 and 2022, no license and milestone revenue – 
related party was recognized related to the Biogen Collaboration Agreement.
The Company considers the collaborative activities associated with the co-development, co-commercialization, and 
co-manufacturing of SAGE-217 products and, through the SAGE-324 Termination effective date, SAGE-324 products in 
the U.S. to be separate units of account within the scope of Topic 808 as the Company and Biogen are both active 
participants in the development and commercialization activities and are exposed to significant risks and rewards that are 
dependent on the development and commercial success of the activities in the arrangement. 
While Biogen is considered the principal in transactions with customers for the sale of ZURZUVAE globally, the 
Company is also engaged in significant commercialization activities, including maintaining its own U.S. direct sales force. 
The Company presents its proportionate share of Biogen’s ZURZUVAE sales to customers in the U.S. as collaboration 
revenue - related party. Payments to or reimbursements from Biogen related to the agreement of the parties to share 
equally in all revenue and costs are accounted for as an increase to collaboration revenue, an increase to or reduction of 
cost of revenues, research and development expenses, or selling, general and administrative expenses, in the consolidated 
statements of operations and comprehensive loss, depending on the nature of the activity.
To record its proportionate share of collaboration revenue from Biogen’s sales of ZURZUVAE to customers in 
the U.S., the Company utilizes certain information from Biogen, including revenue from the sale of the product and 
associated reserves on revenue.
The following table summarizes the Company’s proportionate share of the activity under the Biogen Collaboration 
Agreement accounted for under Topic 808, including activities associated with the sale of ZURZUVAE in the U.S., as 
well as costs during the periods related to the development of SAGE-217 products and SAGE-324 products, as reflected 
in our consolidated statements of operations and comprehensive loss:

representing net reimbursement for amounts due for the three months ended December 31, 2024. As of December 31, 
2023, the Company recorded a collaboration receivable – related party of $83.0 million, consisting of $8.0 million of net 
reimbursement for amounts due for the three months ended December 31, 2023 and the $75.0 million milestone achieved. 
During the year ended December 31, 2024, no payments were made to Biogen and the Company received $118.1 
million from Biogen for the amounts due for the three months ended December 31, 2023 and the nine months ended 
September 30, 2024. During the year ended December 31, 2023, no payments were made to Biogen and the Company 
received $65.7 million from Biogen for the amounts due for the three months ended December 31, 2022 and the nine 
months ended September 30, 2023. During the year ended December 31, 2022, no payments were made to Biogen and the 

F-29
Company received $80.3 million from Biogen for the amounts due for the three months ended December 31, 2021 and the 
nine months ended September 30, 2022.
During the year ended December 31, 2024, the Company recorded $0.9 million of other collaboration revenue 
related to providing development and regulatory support to Biogen in the Biogen Territory under the Biogen 
Collaboration Agreement. During the years ended December 31, 2023 and 2022, no other collaboration revenue was 
recognized related to the Biogen Collaboration Agreement. 
Accounting for the Biogen Stock Purchase Agreement
In connection with the execution of the Biogen Collaboration Agreement, the Company and BIMA entered into the 
Biogen Stock Purchase Agreement. Pursuant to the Biogen Stock Purchase Agreement, the Company sold the Biogen 
Shares to BIMA at a price of approximately $104.14 per share for aggregate consideration of $650.0 million. The sale of 
the shares to BIMA closed on December 31, 2020.
The Biogen Stock Purchase Agreement includes certain standstill provisions that terminate on the earliest of (i) a 
specified regulatory milestone under the Biogen Collaboration Agreement, (ii) the date one year following the termination 
of the Biogen Collaboration Agreement and (iii) the seventh anniversary of the Effective Date. 
The Company determined the fair value of the common shares was determined to be $417.5 million, which was 
$232.5 million less than the proceeds received from BIMA for the issuance of the Company’s common stock under the 
Biogen Stock Purchase Agreement. As such, the $232.5 million in excess proceeds has been included in the $1.1 billion 
transaction price of the Biogen Collaboration Agreement determined above.
8.     Preferred Stock
The Board of Directors of the Company (the “Board”) is authorized, without action by the stockholders, to designate 
and issue up to an aggregate of 5,000,000 shares of preferred stock in one or more series. The Board can designate the

Securities (USA) LLC, as sales agent (“TD Cowen”), with respect to an “at the market offering” program pursuant to 
which the Company may offer and sell shares of its common stock having an aggregate offering price of up to $250.0 
million (the “Shares”), from time to time through TD Cowen (the “ATM Offering”). Upon the Company’s entry into the 
ATM Sales Agreement, the prior sales agreement with Cowen and Company, LLC, an affiliate of TD Cowen, dated 
November 7, 2023 (the “Original Sales Agreement”) was terminated. At the time of such termination, $241.7 million out 
of an aggregate of $250.0 million of shares remained unsold under the Original Sales Agreement. 

F-30

As of December 31, 2024, $250.0 million of shares remain available for issuance and sale under the ATM Sales 
Agreement.
10.     Stock-Based Compensation
Equity Plans
On July 2, 2014, the stockholders of the Company approved the 2014 Stock Option and Incentive Plan (the “2014 
Plan”), which became effective immediately prior to the completion of the Company’s initial public offering. The 2014 
Plan provided for the grant of restricted stock awards, restricted stock units, incentive stock options and non-statutory 
stock options. The 2014 Plan replaced the Company’s 2011 Stock Option and Grant Plan (the “2011 Plan”).
On June 10, 2024, the stockholders of the Company approved the 2024 Equity Incentive Plan (the “2024 Plan”), 
which had been previously approved by the Board. Upon stockholder approval, the 2024 Plan became effective 
immediately and replaced the 2014 Plan. The 2024 Plan provides for the grant of incentive stock options, non-statutory 
stock options, stock appreciation rights, restricted stock, restricted stock units, other stock-based awards, and cash awards. 
The total number of shares initially reserved for issuance under the 2024 Plan is equal to the sum of (i) 5,500,000 shares 
of the Company’s common stock and (ii) such additional number of shares of the Company’s common stock (up to 
11,002,166 shares) as is equal to the number of shares of common stock subject to awards granted under the 2014 Plan 
that were outstanding as of June 10, 2024, and which awards expire, terminate or are otherwise surrendered, cancelled, 
forfeited or repurchased by the Company at their original issuance price pursuant to a contractual repurchase right 
(subject, however, in the case of incentive stock options, to any limitations under the Internal Revenue Code of 1986, as 
amended, and any regulations thereunder).
The Company no longer grants stock options or other awards under either its 2014 Plan or its 2011 Plan, and there 
are no stock options or other awards outstanding under the 2011 Plan. Any stock options and other awards outstanding 
under the 2014 Plan remain outstanding and effective in accordance with their terms.
On December 15, 2016, the Board approved the 2016 Inducement Equity Plan (as amended and restated, the “2016 
Plan”). The 2016 Plan provides for the grant of equity awards to individuals who have not previously been an employee or 
a non-employee director of the Company to induce them to accept employment and to provide them with a proprietary 
interest in the Company. On September 20, 2018, the Board amended the 2016 Plan to increase the total number of shares 
reserved for issuance by 1,200,000 shares. On April 16, 2024, the Board amended the 2016 Plan to reduce the number of 
shares reserved for issuance thereunder to 428,074 shares and to provide that no further grants may be made under the 
2016 Plan after April 16, 2024.

F-31
Terms of equity grants, including vesting requirements, are determined by the Board or the Compensation 
Committee of the Board, subject to the provisions of the applicable plan. Stock options granted by the Company that are 
not performance-based are considered time-based because they vest based on the continued service of the grantee with the 
Company during a specified period following grant. These awards, when granted to employees, generally vest ratably 
over four years, with 25% vesting at the one-year anniversary, and generally expire 10 years after the date of grant.
As of December 31, 2024, the total number of shares underlying outstanding awards under the 2024 Plan, the 2014 
Plan and the 2016 Plan was 8,758,214 and the total number of shares available for future issuance under the 2024 Plan 
was 7,490,967 shares.
On July 2, 2014, the Company’s stockholders approved the 2014 Employee Stock Purchase Plan (the “ESPP”), 
which had been previously approved by the Board. The ESPP became effective upon the completion of the IPO. A total of 
282,000 shares of common stock were authorized for issuance under the ESPP. On June 16, 2022, the Company’s 
stockholders approved an amendment to the ESPP to add 300,000 shares of common stock to the ESPP. On June 16, 
2023, the Company’s stockholders approved an amendment to the ESPP to add 500,000 shares of common stock to the 
ESPP. As amended, a total of 1,082,000 shares of common stock have been authorized for issuance under the ESPP. As of 
December 31, 2024, 662,806 shares have been issued and 419,194 shares are available for future issuance under the 
ESPP.
Option Exchange Program
On January 23, 2024, the Company initiated a tender offer related to a one-time stock option exchange program 
pursuant to which eligible non-executive officer employees were given the opportunity to exchange certain outstanding 
stock options (the “Eligible Options”) to purchase shares of the Company’s common stock for replacement options to 
purchase a lesser number of shares of common stock (the “Option Exchange”) upon the terms and subject to the 
conditions set forth in the Offer to Exchange Eligible Options for Replacement Options dated January 23, 2024 (the 
“Offer to Exchange”). Stock options eligible for exchange had an exercise price per share of $35.00 or greater, in addition 
to certain other requirements, and were exchanged for replacement options with an exercise price per share equal to the 
fair market value of the Company’s common stock on the date of grant of the replacement options, which was February 
21, 2024. The consummation of the Option Exchange was subject to approval by the Company’s stockholders, which 
approval was received at the special meeting of stockholders held on January 31, 2024. The Company accepted for 
exchange Eligible Options to purchase a total of 3,079,608 shares of the Company’s common stock. All tendered Eligible 
Options were cancelled effective as of February 21, 2024, and promptly thereafter, in exchange thereof, the Company 
granted replacement options for a total of 1,483,113 shares of the Company’s common stock, pursuant to the terms of the 
Offer to Exchange and the 2014 Plan. The exercise price per share of the replacement options was $22.20 per share, which 
was the closing price per share of the Company’s common stock on the Nasdaq Global Market on February 21, 2024. The 
replacement options vest over 18 months from the date of grant and have a term of seven years.
The Company expects to incur a total of $1.7 million of additional stock-based compensation expense as a result 
of the Option Exchange, to be recognized over the 18-month vesting period of the replacement options.

2024, 2023 and 2022 was $2.8 million, $1.8 million, and $12.4 million, respectively.
At December 31, 2024, 1,788,137 time-based restricted stock units were both outstanding and unvested, and the total 
unrecognized stock-based compensation expense related to these awards was $13.8 million, which is expected to be 
recognized over the remaining weighted average vesting period of 1.43 years.
Performance restricted stock units
During the year ended December 31, 2022, the Company granted 705,380 performance restricted stock units to its 
employees and consultants. The majority of these performance restricted stock units vest upon the achievement of certain 
clinical and regulatory development milestones related to product candidates and commercial milestones.
During the year ended December 31, 2023, the Company granted 905,012 performance restricted stock units to its 
employees and consultants. The majority of these performance restricted stock units vest upon the achievement of certain 
clinical and regulatory development milestones related to product candidates and commercial milestones. Certain 
performance restricted stock units vest upon the Company reaching specified measures of total stockholder return.
During the year ended December 31, 2024, the Company granted 400,455 performance restricted stock units to its 
employees. The majority of these performance restricted stock units vest upon the achievement of certain commercial 
milestones. Certain performance restricted stock units vest upon the Company reaching specified measures of total 
stockholder return.
Recognition of stock-based compensation expense associated with performance restricted stock units, except for 
those with milestones that are measures of total stockholder return, commences when the performance condition is 
considered probable of achievement, using management’s best estimates, which consider the inherent risk and uncertainty 
regarding the future outcomes of the milestones. Recognition of stock-based compensation associated with performance 
restricted stock units with milestones that are measures of total stockholder return commences on the grant date and is 
recorded independently of the vesting outcomes of the grants.
During the year ended December 31, 2024, the criteria for one vesting milestone for outstanding performance 
restricted stock units was considered probable. The Company recognized stock-based compensation expense related to the 
probable vesting of this performance restricted stock unit of $4.0 million. There remains an estimated $0.4 million of 
expense to be recognized as of December 31, 2024.
As of December 31, 2023 and 2022, for performance restricted stock units that were outstanding, and other than 
performance restricted stock units for which vesting is tied to total stockholder return, the achievement of the milestones 
that had not been met was considered not probable, and therefore no expense has been recognized related to these awards 
in the years ended December 31, 2023 and 2022, respectively. 
During the years ended December 31, 2024 and 2023, the Company recorded $0.8 million and $0.7 million, 
respectively, of stock-based compensation expense related to performance restricted stock units for which vesting is tied 
to total stockholder return.
No performance restricted stock units vested during the year ended December 31, 2022.

F-33
During the year ended December 31, 2023, the criteria for three vesting milestones for outstanding performance 
restricted stock units were achieved. The total fair value of the performance restricted stock units that vested upon 
achievement of these milestones was $9.6 million at vesting date, and the Company recognized stock-based compensation 
expense related to the vesting of these performance restricted stock units of $14.3 million.
During the year ended December 31, 2024, the criteria for one vesting milestone for outstanding performance 
restricted stock units were achieved. The total fair value of the performance restricted stock units that vested upon 
achievement of this milestone was $1.4 million at vesting date, and the Company recognized stock-based compensation 
expense related to the vesting of these performance restricted stock units of $3.6 million.
At December 31, 2024, 1,212,253 performance restricted stock units were both outstanding and unvested, and the 
total unrecognized stock-based compensation expense related to these awards was $42.9 million.

As of December 31, 2024, the Company had unrecognized stock-based compensation expense related to its 
outstanding and unvested time-based stock option awards of $24.1 million, which is expected to be recognized over the 
remaining weighted average vesting period of 3.18 years. 
The intrinsic value of stock options exercised during the years ended December 31, 2024, 2023, and 2022 was 
$0.1 million, $1.9 million and $4.4 million, respectively.
Performance-Based Stock Options
Recognition of stock-based compensation expense associated with performance-based stock options commences 
when the performance condition is considered probable of achievement, using management’s best estimates, which 
consider the inherent risk and uncertainty regarding the future outcomes of the milestones.
As of December 31, 2024, 2023 and 2022, for performance-based stock option grants that were outstanding, the 
achievement of the milestones that had not been met was considered not probable, and therefore no expense has been 
recognized related to these awards in the years ended December 31, 2024, 2023 and 2022, respectively.
During the years ended December 31, 2024, 2023 and 2022, the Company granted no stock options to purchase 
shares of common stock that contain performance-based vesting criteria.
During the years ended December 31, 2024 and 2022, no milestones were achieved under performance-based stock 
options.

F-34
During the year ended December 31, 2023, the criteria for one regulatory development milestone was achieved 
under performance-based stock options granted in connection with the hiring of its chief executive officer. During the 
year ended December 31, 2023, the Company recognized stock-based compensation expense related to this milestone of 
$10.7 million.
As of December 31, 2024, 455,000 performance-based stock options were both outstanding and unvested, the total 
unrecognized stock-based compensation expense related to these awards was $24.9 million before the application of the 
forfeiture rate and the timing of recognition of this stock-based compensation expense is subject to judgment of the 
Company as to when the performance conditions are considered probable of being achieved.

For stock option awards, the fair value is estimated at the grant date using the Black-Scholes option-pricing 
model, taking into account the terms and conditions upon which stock options are granted. For grants with service based 
vesting conditions, the fair value of the stock options is amortized on a straight-line basis for stock option awards to 
employees, non-employee directors and non-employee consultants over the requisite service period of the awards. 
The weighted average grant date fair value per share of stock options granted under the Company’s stock option 
plans during the years ended December 31, 2024, 2023, and 2022 was $14.23, $29.53 and $25.96, respectively.

F-35
The fair value of each stock option granted under the Company’s equity plans has been calculated on the date of 
grant using the following weighted average assumptions:
Year Ended December 31,
2024
2023
2022

Risk-free interest rate
4.24%
3.85%
2.49%
Expected term
6.01 years
6.01 years
6.03 years
Expected dividend yield: the Company has not paid, and does not anticipate paying, any dividends in the foreseeable 
future.
Risk-free interest rate: the Company determined the risk-free interest rate by using a weighted average equivalent to 
the expected term based on the U.S. Treasury yield curve in effect as of the date of grant.
Expected volatility: the Company uses the historical volatility of its publicly traded common stock, as there is 
adequate historical data for the duration of the expected term.
Expected term (in years): the expected term represents the period that the Company’s stock option grants are 
expected to be outstanding. The expected term of the stock options granted to employees, non-employee directors and 
non-employee consultants by the Company has been determined utilizing the “simplified” method for awards that qualify 
as “plain-vanilla” stock options. Under this approach, the weighted average expected life is presumed to be the average of 
the vesting term and the contractual term of the stock option. This approach is used because the Company does not have 
sufficient historical exercise data to provide a reasonable basis upon which to estimate the expected term due to the 
limited period of time that its stock has been publicly traded.
Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures 
differ from estimates. The Company estimates forfeitures based on historical terminations. For the years ended December 
31, 2024, 2023, and 2022, the weighted-average forfeiture rates were 15.1%, 16.6% and 19.2%, respectively.

There is no current or deferred provision for income taxes because the Company has historically incurred and 
utilized operating losses prior to the year ended December 31, 2024. As of December 31, 2024, the Company continues to 
maintain a full valuation allowance against its net deferred tax assets. The reported amount of income tax expense for the 
years differs from the amount that would result from applying domestic federal statutory tax rates to pretax losses 
primarily because of changes in the valuation allowance.

On August 16, 2022, the Inflation Reduction Act of 2022 (the “IRA”) was signed into law. The IRA introduced new 
tax provisions, including a 15.0% corporate alternative minimum tax and a 1.0% excise tax on stock repurchases. The 
provisions of the IRA are effective for periods after December 31, 2022. The enactment of the IRA did not result in any 
material adjustments to the Company’s income tax provision or net deferred tax assets as of December 31, 2024 and 2023.
As of December 31, 2024, the Company had federal net operating loss carryforwards of $2.0 billion, of which $30.4 
million begin to expire in 2033 and the remainder do not expire but are subject to 80% limitation. As of December 31, 
2024, the Company had state net operating loss carryforwards of $1.1 billion that begin to expire in 2033. As of 
December 31, 2024, the Company had federal and state research and development tax credits carryforwards of $90.5 
million and $18.4 million, respectively, which begin to expire in 2031 and 2032, respectively. As of December 31, 2024, 
the Company had federal orphan drug tax credit carryforwards of $40.1 million, which begin to expire in 2034. 
As of December 31, 2024, net deferred tax assets before the valuation allowance increased $61.5 million, primarily 
due to the capitalization of research and development expenses and the increase of federal and state net operating loss 
carryforwards due to the loss generated for the year ended December 31, 2024, offset by the cancelation of vested 
nonqualified stock options resulting from the workforce reductions during the years ended December 31, 2024 and 2023. 
This increase in net deferred tax assets was offset by a corresponding increase in the valuation allowance.
Management of the Company has evaluated the positive and negative evidence bearing upon the realizability of its 
deferred tax assets, which are comprised principally of federal and state net operating loss, capitalized research and 
development expenses and tax credit carryforwards. Under the applicable accounting standards, management has 
considered the Company’s history of losses and concluded that it is more likely than not that the Company will not 
recognize the benefits of its federal and state deferred tax assets. Accordingly, a full valuation allowance of $796.7 million 
and $735.2 million has been established at December 31, 2024 and 2023, respectively. The valuation allowance increased 
by $61.5 million for the year ended December 31, 2024, primarily due to the capitalization of research and development 
expenses and generation of net operating losses, offset by the cancelation of vested nonqualified stock options. The 
valuation allowance increased by $141.9 million and $122.7 million for the years ended December 31, 2023 and 2022, 
respectively, primarily due to the capitalization of research and development expenses and generation of net operating 
losses.
Pursuant to Section 382 of the Internal Revenue Code of 1986, as amended, (the “Code”), and similar state tax law, 
certain substantial changes in the Company’s ownership may result in a limitation on the amount of net operating loss and 
tax credit carryforwards that may be used in future years. Utilization of the net operating loss and tax credit carryforwards 
may be subject to a substantial annual limitation under Section 382 of the Code, due to ownership change limitations that 
have occurred previously or that could occur in the future. These ownership changes may limit the amount of net 

F-38
operating loss and tax credit carryforwards that can be utilized annually to offset future taxable income and tax, 
respectively. The Company completed a Section 382 study through December 31, 2020. Based on the study, the Company 
underwent two ownership changes for Section 382 purposes which occurred on March 11, 2014 and December 31, 2015. 
As a result of the ownership changes, the Company’s net operating loss and tax credit carryforwards as of the ownership 
change dates are subject to limitation under Section 382; however, these limitations are not expected to cause any of the 
impacted net operating loss and tax credit carryforwards to expire unused. Subsequent ownership changes, as defined by 
Section 382, may potentially further limit the amount of net operating loss and tax credit carryforwards that could be 
utilized to offset future taxable income and tax. 
The Company applies the authoritative guidance on accounting for and disclosure of uncertainty in tax positions, 
which requires the Company to determine whether a tax position of the Company is more likely than not to be sustained 
upon examination, including resolution of any related appeals of litigation processes, based on the technical merits of the 
position. For tax positions meeting the more likely than not threshold, the tax amount recognized in the financial 
statements is reduced by the largest benefit that has a greater than fifty percent likelihood of being realized upon the 
ultimate settlement with the relevant taxing authority. 
The following table reconciles the beginning and ending amounts of gross unrecognized tax benefits, excluding 
interest and penalties, if any, for the years ended December 31, 2024, 2023, and 2022:

For the years ended December 31, 2024, 2023, and 2022, the increases in unrecognized tax benefits related to 
current year and prior year tax positions with respect to the Company’s federal and state tax credits.
The Company’s policy is to record interest and penalties related to income taxes as part of the tax provision. As of 
December 31, 2024 and 2023, the Company had no accrued interest or penalties related to income taxes and no amounts 
have been recognized in the Company’s statements of operations and comprehensive loss for the years ended December 
31, 2024, 2023, and 2022.
The Company files tax returns as prescribed by the tax laws of the jurisdictions in which it operates. In the normal 
course of business, the Company is subject to examination by federal, state and foreign jurisdictions, where applicable. 
There are currently no pending tax examinations, and the Company’s tax returns are generally open under statute from 
2021 to the present. Tax attributes such as net operating losses and tax credits generated prior to 2021 and utilized in open 
years may still be adjusted upon examination.
13.    Employee Benefit Plan
The Company maintains a 401(k) profit sharing plan (the “401(k) Plan”) for its employees. Each employee may 
elect to contribute a portion of his or her compensation to the 401(k) Plan, subject to annual limits established by the 
Internal Revenue Service. For the years ended December 31, 2024, 2023, and 2022, the Company matched 50% of 
eligible contributions to the 401(k) Plan up to 6% of employee contributions. For the years ended December 31, 2024, 
2023, and 2022 the Company contributed $2.9 million, $3.9 million, and $3.0 million, respectively, to the 401(k) Plan.
14.     Restructuring
In August 2023, the Company implemented a strategic corporate reorganization and reprioritization of its pipeline 
(the “2023 Restructuring”). The 2023 Restructuring included a reduction of the Company’s workforce by approximately 
40%, designed to right-size the organization as the Company worked to achieve sustained growth and support the 
commercialization of ZURZUVAE for the treatment of women with PPD. During the year ended December 31, 2023, the 

F-39
Company recorded $33.4 million of expense related to the 2023 Restructuring, primarily for one-time termination benefits 
to the affected employees, primarily for cash payments of severance, healthcare benefits and outplacement assistance. 
As of December 31, 2024, the Company has paid substantially all of the accrued 2023 Restructuring charges and 
during the year ended December 31, 2024, the Company recorded a $0.5 million reversal of related expense. Total 
restructuring charges incurred through December 31, 2024 are $32.9 million, which is the total expected amount to be 
incurred.
In October 2024, the Company implemented a plan to reorganize its business operations (the “2024 Restructuring”), 
including to focus investment on the ongoing launch of ZURZUVAE for the treatment of women with PPD and its 
prioritized pipeline development efforts. As part of the 2024 Restructuring, the Company implemented a reduction of 
approximately 33% of the Company’s total workforce and approximately 55% of the Company’s research and 
development workforce. During the year ended December 31, 2024, the Company recorded $22.3 million of expense for 
the 2024 Restructuring, primarily for one-time termination benefits to the affected employees, primarily consisting of cash 
payments of severance, healthcare benefits and outplacement assistance. 
The Company expects that substantially all of the accrued 2024 Restructuring charges as of December 31, 2024 will 
be paid in cash by June 30, 2025. The Company expects to incur a total of $23.6 million of expense related to the 2024 
Restructuring, including $1.3 million of expense which will be recorded in future periods, primarily consisting of one-
time termination benefits.

15.     Segment Information
Operating segments are defined as components of an entity for which separate financial information is available and 
that is regularly reviewed by the Chief Operating Decision Maker (“CODM”) in deciding how to allocate resources to an 
individual segment and in assessing performance. The Company operates as a single reporting segment, focused on 
discovering, developing and delivering brain health medicines. The Company’s measure of segment profit or loss is net 
loss. The CODM is the chief executive officer (“CEO”). The CODM manages and allocates resources to the operations of 
the Company on a total company basis. Managing and allocating resources on a consolidated basis enables the CEO to 
assess the overall level of resources available and how to best deploy these resources across functions, therapeutic areas 
and research and development projects that are in line with the Company’s long-term company-wide strategic goals. 
Consistent with this decision-making process, the CEO uses consolidated financial information for purposes of evaluating 
performance, forecasting future period financial results, allocating resources and setting incentive targets. Operating 
expenses are used to monitor budget versus actual results. The CODM also uses net loss in competitive analysis by 
benchmarking to the Company’s peer group. The competitive analysis along with the monitoring of budgeted versus 
actual results are used in assessing performance of the segment. All the Company’s long-lived assets are held in the 
United States and all the Company’s revenues are derived from the United States. 

F-40
The following table is representative of the significant expense categories regularly provided to the CODM when 
managing the Company’s single reporting segment. A reconciliation to the consolidated net loss for the years ended 
December 31, 2024, 2023 and 2022 is included at the bottom of the table below.

16.     Subsequent Events
On January 10, 2025, the Company received an unsolicited, non-binding acquisition proposal from Biogen to 
acquire all outstanding shares of the Company not already owned by Biogen for $7.22 per share. On January 27, 
2025, the Board of Directors (the “Board”) unanimously rejected the unsolicited, non-binding acquisition proposal 
received from Biogen. The Company further announced that the Board has initiated a process to explore strategic 
alternatives for the Company. On January 16, 2025, the Company commenced litigation against Biogen in the 
Delaware Court of Chancery seeking declaratory, injunctive and other relief. In its complaint, the Company alleges 
that Biogen breached the standstill provision in the Biogen Stock Purchase Agreement by making an unsolicited 
acquisition proposal and related public disclosures. See Note 6, Commitments and Contingencies, for further details.
