CORAL GABLES, Fla., Nov. 05, 2025 (GLOBE NEWSWIRE) -- Catalyst Pharmaceuticals, Inc. (“Catalyst” or “Company”) (Nasdaq: CPRX) today reported financial results for the third quarter of 2025 and provided a business update.

“Throughout 2025, we have continued to execute on our commercial growth initiatives to drive adoption of FIRDAPSE® and AGAMREE®, resulting in another quarter of strong financial performance," stated Rich Daly, President and CEO of Catalyst. "Our third quarter performance was driven by our best-in-class product portfolio and our focus on creating value for patients taking FIRDAPSE and AGAMREE who participate in our Catalyst Pathways® program. We believe that this program both enhances access as well as contributes to medication compliance and persistence."

Mr. Daly continued: "Finally, we continue to evaluate strategically aligned opportunities to further strengthen our portfolio and expand our reach to serve more patients living with rare diseases. As signaled by our increased 2025 total revenue guidance and our recently announced share repurchase program, we remain confident in our growth trajectory and look forward to continued value creation.”

Third Quarter 2025 Financial Highlights

• Achieved net product revenues of $148.4 million for Q3 2025, a 17.4% increase over net product revenues for the third quarter of 2024.
  
  
• Raising total revenue guidance for full year 2025 to between $565 million and $585 million.
  
  
  • Raising 2025 net product revenue guidance for AGAMREE to between $105 million and $115 million.
  • Raising 2025 net product revenue guidance for FYCOMPA® to between $100 million and $110 million.
  • Reaffirming full-year 2025 net product revenue guidance for FIRDAPSE to between $355 million and $360 million.
    

• Achieved record FIRDAPSE net product revenue in Q3 2025 of $92.2 million, reflecting a 16.2% increase over Q3 2024 net product revenue, driven primarily by sustained organic growth from new patients, enhanced dosing, persistence, and further penetration in the idiopathic and cancer-associated Lambert-Eaton myasthenic syndrome (LEMS) markets.
  
  
• Achieved third quarter 2025 net product revenue for AGAMREE of $32.4 million, demonstrating continued demand and further, albeit still early, penetration into nearly all of the Duchenne muscular dystrophy (DMD) centers of excellence.  Catalyst continues to actively enroll patients in the SUMMIT study, an open-label five-year follow-up study designed to evaluate the long-term clinical safety profile of AGAMREE, including potential benefits on behavior, stature, bone health, and cardiovascular health.
  
  
• Reported stronger than originally forecasted net product revenue for FYCOMPA of $23.8 million for Q3 2025, a 25.8% decrease compared to Q3 2024 net product revenue. This reflects solid performance following the entry of the first generic tablet version of the product, which entered the market at the end of Q2 2025. Revenues are forecasted to decline in future periods as additional generic competition enters the market.

Recent Business Highlights

• On August 26, 2025, Catalyst announced the settlement of FIRDAPSE (amifampridine) patent litigation with Lupin Ltd. and Lupin Pharmaceuticals, Inc. (collectively, “Lupin”). As part of the settlement, Lupin received a license to market generic FIRDAPSE beginning in February 2035, on the same market entry date as Teva Pharmaceuticals had previously agreed to in their settlement with the Company. This settlement leaves only one patent case pending against Hetero USA, Inc. A tentative trial date has been set for March 2026, which is prior to the expiration of the automatic 30-month stay on May 26, 2026. There can be no assurance as to the outcome of this matter.
  
  
• On October 1, 2025, Catalyst announced that its Board of Directors approved a share repurchase program under which the Company will purchase up to $200 million of its outstanding common stock between October 1, 2025, and December 31, 2026, reflecting Catalyst’s strong balance sheet and confidence in its long-term financial outlook. Catalyst is using cash on hand to fund its share repurchase program and believes it can execute this program without impairing the advancement of its business development strategy. Through November 5, 2025, the Company has repurchased 405,092 shares of its outstanding common stock for an aggregate purchase price of approximately $8.4 million ($20.74 average price per share).
  
  
• On October 2, 2025, KYE Pharmaceuticals, Inc. (KYE) issued a press release announcing that Health Canada issued a Notice of Compliance for KYE’s New Drug Submission to commercialize AGAMREE in Canada. This approval marks the first therapy approved to treat DMD and addresses a significant unmet need for DMD patients in Canada.
  
  
• Catalyst has reviewed and evaluated over 100 prospective clinical and commercial stage acquisition targets so far this year. The Company continues to focus its efforts on identifying near-term accretive rare disease (orphan) assets that provide a clinically differentiated profile that address unmet medical needs. Catalyst employs a disciplined, comprehensive and exhaustive approach to evaluate opportunities that it believes will add significant value. However, no such agreements have been entered into in 2025.
  
  
• As announced yesterday, Catalyst has been recognized among the BioSpace 2026 Best Places to Work for the second consecutive year, ranking number 13 out of 30 of U.S. employers in the small company category.

GAAP net income: GAAP net income for the third quarter of 2025 was $52.8 million ($0.43 per basic and $0.42 per diluted share), compared to GAAP net income of $43.9 million ($0.37 per basic and $0.35 per diluted share) for the third quarter of 2024.

Cash and cash equivalents

Cash and cash equivalents were $689.9 million as of September 30, 2025. The cash and cash equivalents balance as of September 30, 2025, was impacted primarily by a change in the payment terms resulting from the renegotiation of a contract between the Company and a customer. Under the revisions to the contract with this customer, among other changes, the Company is now paying reduced fees to the customer (which are recorded as a reduction in gross-to-net expenses), but the customer is paying amounts due on its obligations to Catalyst on a monthly basis rather than a semi-monthly basis (as required under the previous contract terms). As a result of this change, the payment of approximately $24.9 million that the Company would have received, based upon the previous due date, at the end of September 2025 under the previous contract terms was received on October 2, 2025.

Catalyst’s Form 10-Q for the third quarter of 2025, which was filed with the U.S. Securities and Exchange Commission on November 5, 2025, provides more detailed financial information and analysis of Catalyst’s financial condition and results of operations.
