Key catalyst

Q1 2026 results and FY2026 guidance reaffirmed [#8-K-2026-05-06] • 2026-05-06

Expected move: +7%

Biggest risk

SG&A stepped up sharply, Q1 EPS was only $0.02 despite $268M of revenue, and the thesis still depends on a small set of commercial assets plus binary clinical outcomes; any slowdown in DAYBUE or weak readouts would pressure the stock.

Invalidation

Break below $15 or thesis failure.

What would change my mind?

DAYBUE is growing, NUPLAZID remains resilient, management reaffirmed FY2026 guidance, and the company has two dated 2H2026 program milestones supported by the May 2026 8-K exhibit.

BearKey bullets

Both remlifanserin and the Japan trofinetide program are binary catalysts; negative data would likely compress the multiple.
Commercial expense growth is steep: SG&A rose to $171M from $126M, limiting operating leverage.
The stock depends heavily on DAYBUE/NUPLAZID performance, so any launch slowdown or prescription softness would matter quickly.

Commentary

Primary-source tone is constructive because revenue grew, both marketed products contributed, guidance was reaffirmed, and the May 2026 8-K exhibit identifies two dated 2H2026 program milestones. The offset is higher commercial spending, modest Q1 earnings power, and limited visible analyst-revision support in the packet. No social-context signal was available, so sentiment should not override the cautious primary-source monitoring view.

Remlifanserin Phase 2 topline readout in Alzheimer disease psychosis [#8-K-2026-05-06]
2026-09-15
The company said Phase 2 topline results for remlifanserin in Alzheimer disease psychosis remain on track for the August to October 2026 timeframe. This is a company-specific forward catalyst, but it is binary and should be treated as a monitoring item rather than a confirmed positive driver.
Prob 50% • Move 8% • Priced-in 38%
Trofinetide Japan trial topline results [#8-K-2026-05-06]
2026-10-15
Acadia said accelerated enrollment in the trofinetide clinical trial in Japan moved expected topline results to the September to November 2026 timeframe, giving the stock a second dated program-specific milestone in 2H2026.

Risks

Both remlifanserin and the Japan trofinetide program are binary catalysts; negative data would likely compress the multiple.
Commercial expense growth is steep: SG&A rose to $171M from $126M, limiting operating leverage.
The stock depends heavily on DAYBUE/NUPLAZID performance, so any launch slowdown or prescription softness would matter quickly.
There is limited visible post-print analyst re-rating in the packet, so a stronger rerating thesis lacks confirmation.

Peers

Symbol	Summary
OGN	Similar-sized commercial pharma with existing marketed products; useful for comparing execution, margins, and launch durability, though therapeutic overlap is limited.
CRNX	Mid-cap biopharma with catalyst-driven valuation sensitivity; useful for reading broader biotech risk appetite, but it is less commercial-stage than ACAD.
