NEW YORK, May 4, 2026 (Globe Newswire) – Axsome Therapeutics, Inc. (NASDAQ: AXSM), a biopharmaceutical company leading a new era in the treatment of central nervous system (CNS) disorders, today announced financial results for the first quarter of 2026 and provided a general business update.

"Axsome had a tremendous start to 2026. Our commercial business delivered robust year-over-year growth in the first quarter, Auvelity was approved by the FDA as a first-in-class medicine for the treatment of agitation associated with dementia due to Alzheimer's disease, and we added a potentially first-in-class Phase 3-ready PDE10A inhibitor for schizophrenia and Tourette syndrome to our pipeline," said Herriot Tabuteau, MD, Chief Executive Officer of Axsome Therapeutics. "The approval of Auvelity for Alzheimer's disease agitation highlights our research and development productivity, and commitment to deliver innovation to patients living with serious brain health disorders. With three differentiated marketed medicines now approved for four highly prevalent CNS conditions, and an innovative pipeline which includes six potentially first-in-class and best-in-class product candidates targeting ten conditions with significant unmet medical need in psychiatry and neurology, Axsome is positioned to advance the frontiers of brain health for patients, and deliver substantial value for shareholders."

**First Quarter 2026 Financial Highlights**

• Total net product revenue was $191.2 million for the first quarter of 2026, representing 57% year-over-year growth. Total net product revenue for the comparable period in 2025 was $121.5 million.

• AUVELITY net product revenue was $153.2 million for the first quarter of 2026, representing 59% year-over-year growth. AUVELITY net product sales for the comparable period in 2025 were $96.2 million.

• SUNOSI net product revenue was $33.9 million for the first quarter of 2026, representing 34% year-over-year growth, which consisted of $32.6 million in net product sales and $1.3 million in royalty revenue associated with SUNOSI sales in out-licensed territories. SUNOSI net product revenue for the comparable period in 2025 was $25.2 million, which consisted of $24.1 million in net product sales and $1.1 million in royalty revenue.

• SYMBRAVO net product revenue was $4.1 million for the first quarter of 2026.

• Total cost of revenue was $14.7 million for the first quarter of 2026. Total cost of revenue for the comparable period in 2025 was $9.8 million.

------

• Research and development (R&D) expenses were $52.7 million for the first quarter of 2026, compared to $44.8 million for the comparable period in 2025. The increase primarily reflects a one-time acquisition-related expense.

• Selling, general, and administrative (SG&A) expenses were $185.0 million for the first quarter of 2026, compared to $120.8 million for the comparable period in 2025. The increase primarily reflects the acceleration of pre-launch activities for AUVELITY for the Alzheimer's disease agitation indication and commercialization activities for AUVELITY, including direct-to-consumer advertising, and commercialization activities for SYMBRAVO.

• Net loss for the first quarter of 2026 was $64.5 million, or $(1.26) per share, compared to a net loss of $59.4 million, or $(1.22) per share, for the comparable period in 2025. The net loss in the first quarter of 2026 includes $23.4 million in stock-based compensation expense.

• Cash and cash equivalents totaled $305.1 million at March 31, 2026, compared to $322.9 million at December 31, 2025.

• Shares of common stock outstanding were 51,420,445 at March 31, 2026.

**Financial Guidance**

• Axsome believes that its current cash is sufficient to fund anticipated operations into cash flow positivity, based on the current operating plan.

**Commercial Highlights**

***AUVELITY***

AUVELITY is a first-in-class oral NMDA receptor antagonist and sigma-1 receptor agonist approved in the U.S. for the treatment of major depressive disorder in adults, and for the treatment of agitation associated with dementia due to Alzheimer's disease.

• Approximately 223,000 prescriptions were written for AUVELITY in the first quarter of 2026, a 35% increase compared to the first quarter of 2025, with prescriptions consistent with the fourth quarter of 2025.

• Payer coverage for AUVELITY across all channels is currently at approximately 86% of all lives. The proportion of lives covered in the commercial and government (Medicare and Medicaid) channels are approximately 78% and 100%, respectively.

• In April 2026, the U.S. Food and Drug Administration (FDA) approved AUVELITY for the treatment of agitation associated with dementia due to Alzheimer's disease. AUVELITY is a first-in-class pharmacotherapy that targets the NMDA and sigma-1 receptors, which are thought to modulate key neurotransmitters implicated in Alzheimer's disease. The commercial launch of AUVELITY in Alzheimer's disease agitation is on track for June 2026.

• The recently announced expansion of the AUVELITY sales force is substantially complete. Our expanded sales team of approximately 630 sales representatives will engage a broad group of prescribers, including primary care providers, psychiatrists, neurologists, and geriatric specialists, leveraging strong and growing demand in MDD and the substantial opportunity in Alzheimer's disease agitation.

***SUNOSI***

SUNOSI is the first and only DNRI approved for the treatment of excessive daytime sleepiness associated with obstructive sleep apnea or narcolepsy.

------

• Approximately 54,000 prescriptions were written for SUNOSI in the U.S. in the first quarter of 2026, representing an increase of 16% compared to the same period in 2025, with prescriptions consistent with the fourth quarter of 2025.

• Payer coverage for SUNOSI across all channels is approximately 83% of all covered lives. The proportion of lives covered in the commercial and government channels are approximately 96% and 60%, respectively.

***SYMBRAVO***

SYMBRAVO is an oral, rapidly absorbed, multi-mechanistic, COX-2 preferential inhibitor and 5-HT1B/1D agonist approved in the U.S. for the acute treatment of migraine with or without aura in adults.

• Approximately 17,000 prescriptions were written for SYMBRAVO in the first quarter of 2026, representing a 36% increase compared to the fourth quarter of 2025.

• Payer coverage for SYMBRAVO in the commercial channel expanded by 17 million new covered lives, effective May 2026. Overall payer coverage for SYMBRAVO across all channels is now at approximately 57% of all lives, with the proportion of covered lives in the commercial and government channels at approximately 56% and 57%, respectively.

• Based on SYMBRAVO's growth since launch and increased demand, Axsome is expanding the SYMBRAVO sales force from 100 to 150 representatives. The expansion will support broader reach within the primary care market while deepening engagement with headache specialists and neurologists nationwide.

**Development Pipeline**

Axsome is advancing an industry-leading neuroscience pipeline of multiple, innovative, late-stage, product candidates addressing a broad range of serious psychiatric and neurological conditions. Recent and anticipated progress for key pipeline programs is summarized below.

***AXS-05***

• **Attention Deficit Hyperactivity Disorder:** Axsome is on track to initiate two pediatric Phase 3 trials of solriamfetol in ADHD, one in children and one in adolescents, in the second quarter of 2026.

• **Major Depressive Disorder:** In February 2026, Axsome initiated the CLARITY study, a Phase 3, double-blind, placebo-controlled, multicenter, randomized withdrawal trial evaluating the efficacy and safety of solriamfetol for the treatment of MDD with EDS symptoms. The primary endpoint is the time from randomization into the double-blind treatment period to relapse of depressive symptoms.

------
