Financial Results

Revenues

Total revenues comprising of net product sales from NUPLAZID and DAYBUE were $278.6 million, up 11% from the third quarter of 2024.

Net product sales of NUPLAZID were $177.5 million in the third quarter of 2025, an increase of 12% as compared to $159.2 million for the third quarter of 2024. The 12% year-over-year increase in net product sales of NUPLAZID included 9% volume growth and a higher average net selling price in 2025 compared to 2024.

Net product sales of DAYBUE were $101.1 million for the third quarter of 2025, an increase of 11% as compared to $91.2 million for the third quarter of 2024. The increase in net product sales of DAYBUE was all attributable to the growth in unit sales as the Company shipped to over 1,000 unique patients, including patients outside the U.S.

Research and Development

Research and development expenses were $87.8 million, compared to $66.6 million for the three months ended September 30, 2025, and 2024, respectively. The increase was primarily due to increased clinical trial and personnel expenses.

Selling, General and Administrative

Selling, general and administrative expenses were $133.4 million and $133.3 million for the three months ended September 30, 2025, and 2024, respectively.

Net Income

For the three months ended September 30, 2025, Acadia reported net income of $71.8 million, or $0.42 per diluted share, compared to net income of $32.8 million, or $0.20 per common share, for the same period in 2024. The increase in net income reflects both an increase in pre-tax income, and a tax benefit recognized in the third quarter of 2025. The tax benefit primarily resulted from a one-time impact from the One Big Beautiful Bill Act, enacted during the third quarter of 2025, which provides immediate expensing of domestic R&D spending.

Cash and Investments

At September 30, 2025, Acadia’s cash, cash equivalents and investment securities totaled $847.0 million, compared to $756.0 million at December 31, 2024.

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.
