Conference Call and Webcast to be Held on August 7, 2025, at 8:30 AM ET

CORAL GABLES, Fla., Aug. 06, 2025 (GLOBE NEWSWIRE) -- Catalyst Pharmaceuticals, Inc. ("Catalyst" or "Company") (Nasdaq: CPRX), today reported record financial results for the second quarter and first half of 2025, and provided a business update.  

“Catalyst’s record performance reflects disciplined execution and sustained demand across our portfolio, highlighting the meaningful impact our therapies have for patients,” said Richard J. Daly, president and chief executive officer of Catalyst. “With portfolio momentum, focused execution, and a disciplined approach to growth, we are well-positioned to achieve our 2025 guidance and remain confident in our ability to deliver value for patients, providers, and our stakeholders.”

As expected, second-quarter results reflect a one-time timing anomaly stemming from last year’s industry-wide Change Health insurance claims processing disruption, which resulted in an increase in claims adjudications in Q2 2024. The underlying demand for FIRDAPSE remains strong despite this temporary impact. In the first half of 2025, FIRDAPSE net revenues grew 16.9% over the same period in 2024, demonstrating the strength and resilience of our business. FIRDAPSE remains firmly on its multi-quarter growth trajectory.

AGAMREE extended its momentum with robust triple-digit growth of 212.9% over the second quarter 2024 and 398.0% for the first half of 2025, achieving record revenue driven by accelerating physician adoption and continued uptake following its mid-March 2024 launch. FYCOMPA also delivered a strong revenue contribution and demonstrated durability following first approval of a generic version of the tablets in late May.
