"2025 is off to a strong start for Acadia, achieving total revenue of $244.3 million in the first quarter," said Catherine Owen Adams, Chief Executive Officer. "DAYBUE has achieved meaningful patient growth for the first time since the second quarter of 2024, serving more patients this quarter than in any prior quarter, and NUPLAZID continues to drive strong momentum from the direct-to-consumer campaign we launched last year. We're continuing to execute on our commitment to expand the DAYBUE franchise globally and recently served the first patient outside the U.S. through our managed access program in the European Union. As we look ahead, we're excited to share that we now expect the topline results from our COMPASS PWS Phase 3 study of ACP-101 early in the fourth quarter of 2025. We are also looking forward to sharing more details about our pipeline programs at our inaugural R&D Day next month."

Company Updates

• During the first quarter, the Company reached a record high with 954 unique patients receiving a DAYBUE shipment.
• In May, the Company completed its planned 30% expansion of the DAYBUE field force to support broader engagement with healthcare professionals that treat Rett syndrome patients.
• In April, the first shipment of DAYBUE was made to a Rett syndrome patient in the European Union under Acadia's managed access program.
• As a result of favorable enrollment trends in the COMPASS PWS Phase 3 study of ACP-101 (intranasal carbetocin) in Prader Willi Syndrome, the Company now expects topline results from the study early in the fourth quarter of 2025. If results are positive, the Company anticipates submitting a New Drug Application to the U.S. Food and Drug Administration in the first quarter of 2026.

Financial Results

Revenues

Total revenues comprising of net product sales from NUPLAZID and DAYBUE were $244.3 million, up 19% from the first quarter of 2024.

Net product sales of NUPLAZID were $159.7 million in the first quarter of 2025, an increase of 23% as compared to $129.9 million for the first quarter of 2024. The 23% year-over-year increase in net product sales of NUPLAZID included 6% volume growth in 2025 compared to 2024 and a seasonal reduction in gross to net from the Medicare Part D redesign as part of the Inflation Reduction Act.

Net product sales of DAYBUE were $84.6 million for the first quarter of 2025, an increase of 11% as compared to $75.9 million for first quarter of 2024. The increase in net product sales of DAYBUE was primarily due to the growth in unit sales as the Company shipped to more unique patients.

Research and Development

Research and development expenses were $78.3 million, compared to $59.7 million for the three months ended March 31, 2025, and 2024, respectively. The increase was mainly due to increased costs from clinical stage programs.

Selling, General and Administrative

Selling, general and administrative expenses were $126.4 million and $108.0 million for the three months ended March 31, 2025, and 2024, respectively. The increase for this period was primarily driven by the costs related to the consumer activation program to support the NUPLAZID franchise and higher commercial operation expenses for the planned expansion of the DAYBUE team.

Net Income

For the three months ended March 31, 2025, Acadia reported net income of $19.0 million, or $0.11 per common share, compared to net income of $16.6 million, or $0.10 per common share, for the same period in 2024.

Cash and Investments

At March 31, 2025, Acadia's cash, cash equivalents and investment securities totaled $681.6 million, compared to $756.0 million at December 31, 2024. While cash flow from operating activities was positive in the first quarter, the Company made total payments to Neuren Pharmaceuticals Limited (Neuren) in the amount of $98.8 million during the quarter related to Neuren's share of the net proceeds from the Company's recent sale of its Rare Pediatric Disease Priority Review Voucher and an annual net sales milestone.

About NUPLAZID^® (pimavanserin)

Pimavanserin is a selective serotonin inverse agonist and antagonist preferentially targeting 5-HT2A receptors. These receptors are thought to play an important role in neuropsychiatric disorders. In vitro, pimavanserin demonstrated no appreciable binding affinity for dopamine (including D2), histamine, muscarinic, or adrenergic receptors. Pimavanserin was approved for the treatment of hallucinations and delusions associated with Parkinson's disease psychosis by the U.S. Food and Drug Administration in April 2016 under the trade name NUPLAZID.

About DAYBUE^® (trofinetide)

Trofinetide is a synthetic version of a naturally occurring molecule known as the tripeptide glycine-proline-glutamate (GPE). The mechanism by which trofinetide exerts therapeutic effects in patients with Rett syndrome is unknown. Trofinetide was approved for the treatment of Rett syndrome in adults and pediatric patients 2 years of age and older by the U.S. Food and Drug Administration in March 2023 under the trade name DAYBUE.
