**Exhibit 99.1**

**Acadia Pharmaceuticals Reports First Quarter 2026 Financial Results and Reaffirms 2026 Financial Guidance**

*- First quarter DAYBUE*<sup>®</sup> *GAAP net sales of $101 million, up 20% year-over-year; Successful Launch of DAYBUE STIX Underway* 

 *- First quarter NUPLAZID*<sup>®</sup>*GAAP net sales of $167 million, up 6% year-over-year on a non-GAAP adjusted basis*

*- Reaffirms expectation for topline results from the Phase 2 remlifanserin study in Alzheimer's disease psychosis between August and October 2026*

**SAN DIEGO, CA, May 6, 2026** – Acadia Pharmaceuticals Inc. (Nasdaq: ACAD), today announced its financial results for the first quarter ended March 31, 2026.

"Acadia delivered a solid first quarter of 2026 with total revenues of $268 million, driven by a strong start from DAYBUE, which generated sales of $101 million," said Catherine Owen Adams, Chief Executive Officer. "We are very encouraged by the early enthusiasm for DAYBUE STIX, which is now broadly available in the U.S., and by the initial uptake during our focused launch. NUPLAZID generated sales of $167 million, supported by strong new referrals and underlying demand, with performance strengthening as the quarter progressed. As we look ahead, we remain focused on advancing our deep, differentiated pipeline, with remlifanserin representing a key value driver as we approach expected Phase 2 topline data in Alzheimer's disease psychosis later this year. We are reaffirming our full year guidance and remain confident in our ability to deliver long-term value for both patients and shareholders."

**Company Updates**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Full launch of DAYBUE STIX (trofinetide) in the U.S. is underway, with ~30% of STIX patients being either treatment-naive or returning after previously discontinuing the liquid formulation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Phase 2 topline results readout from the remlifanserin Alzheimer's disease psychosis study remains on track for August to October 2026 timeframe.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Accelerated enrollment in the trofinetide clinical trial in Japan, with topline results now anticipated in the September to November 2026 timeframe.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Delphi expert consensus panel recently recommended DAYBUE as part of the standard of care for eligible patients with Rett syndrome.<sup>1</sup>

**Financial Results**

*Revenues*

GAAP total revenues, comprised of net product sales from NUPLAZID and DAYBUE, were $268 million for the first quarter of 2026, up 10% as compared to GAAP total revenues of $244 million in the first quarter of 2025, and up 11% as compared to non-GAAP adjusted total revenues of $242 million in the first quarter of 2025.

GAAP net product sales of NUPLAZID were $167 million for the first quarter of 2026, up 5% compared to GAAP net product sales of $160 million for the first quarter of 2025, and up 6% as compared to non-GAAP adjusted net product sales of $157 million for the first quarter of 2025.

------

Net product sales of DAYBUE were $101 million for the first quarter of 2026, an increase of 20% as compared to $85 million for the first quarter of 2025.

A reconciliation of NUPLAZID non-GAAP adjusted net sales and non-GAAP adjusted total revenues is provided in Table 1. A description of these adjustments is included under 'Non-GAAP Financial Measures.'

Selling, general and administrative expenses for the first quarter of 2026 were $171 million, compared to $126 million for the same period of 2025.

*About NUPLAZID*<sup>®</sup> *(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*<sup>®</sup> *(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 or DAYBUE STIX.

*Non-GAAP Financial Measures*

This press release contains the following financial measures that that do not comply with U.S. generally accepted accounting principles (GAAP): non-GAAP adjusted net sales for NUPLAZID for the first quarter of 2025 and non-GAAP adjusted total revenues for the first quarter of 2025. In preparing these non-GAAP financial results, the Company includes adjustments made to reflect the impact of a change in estimate related to NUPLAZID IRA rebate accruals. Please refer to our press release dated February 25, 2026, for additional details. These non-GAAP financial measures complement GAAP results and are used by management to analyze financial performance and evaluate period-to-period changes. Management believes these non-GAAP financial measures are useful to investors and other users of the Company's financial statements to facilitate period-to-period comparability. These non-GAAP financial measures are not meant to be considered as a substitute for comparable GAAP measures; should be read in conjunction with the Company's consolidated financial statements prepared in accordance with GAAP; have no standardized meaning prescribed by GAAP; and are unlikely to be comparable with non-GAAP disclosures released by other companies.
