CORAL GABLES, Fla. August 9, 2022—Catalyst Pharmaceuticals, Inc. (“Catalyst”) (Nasdaq: CPRX), a commercial-stage biopharmaceutical company focused on in-licensing, developing, and commercializing novel medicines for patients living with rare diseases, today reported financial results for the second quarter 2022 and provided a corporate update. These results marked a quarter of record revenues from FIRDAPSE net sales and reflect the 5^th period of consecutive quarter-over-quarter growth for Catalyst.

“Catalyst’s performance in the first half of the year and into the third quarter continues to be on a strong footing, and we have gained great momentum toward achieving our key strategic objectives for the year,” stated Patrick J. McEnany, Chairman and CEO of Catalyst. “We are pleased with the continued uptake of FIRDAPSE and patient demand, partially resulting from the favorable Appellate Court ruling that removed Ruzurgi from the market on February 1, 2022, as well as robust organic growth, which is providing strong operational growth in line with our total revenue guidance for 2022. In fact, at this time we are comfortable stating that our revenue guidance for the year is expected to be at the upper end of our previous total revenue forecast.”

McEnany continued, “We intend to build on our momentum with a clear priority to diversify our product portfolio with innovative therapies that address unmet medical needs in other rare diseases. Looking ahead, we are optimistic about our future as we remain committed to the patient community we serve and confident in our full-year outlook to drive sustainable growth and create long-term value for our various stakeholders. These efforts along with our continued fiscal discipline, uniquely position Catalyst to deliver sustainable value for our stockholders while supporting our mission for people living with rare diseases.”

RECENT BUSINESS HIGHLIGHTS

• Achieved record net product revenue of $53.0 million for Q2 2022, representing a significant 57.7% year-over-year increase and a 23.3% increase compared to Q1 2022, driven by the transition of Ruzurgi patients converting to FIRDAPSE treatment and robust organic growth.

• Settled our U.S. disputes with Jacobus Pharmaceuticals, which included a settlement of our U.S. patent infringement litigation against Jacobus and a resolution of our litigation challenging the Ruzurgi approval. As part of the settlement, we acquired the U.S. and Mexico rights to develop and commercialize Ruzurgi, the existing inventory of Ruzurgi, and certain know-how and intellectual property, including two U.S. patents. We intend to list one of these patents in the FDA’s Orange Book to add to our patent protection for FIRDAPSE, potentially extending our patent protection for FIRDAPSE until February 25, 2037, and bringing the total number of U.S. patents that we have listed in the Orange Book seeking to protect FIRDAPSE to six.

• FDA accepted for review our supplemental New Drug Application seeking approval for the use of FIRDAPSE as a treatment for pediatric LEMS patients.

• Continued to advance on strategic growth initiatives to diversify our product portfolio with innovative therapies that address unmet needs in other rare diseases.

• Established a framework for our initial Environmental, Social, and Governance report.

¹ Statements made in this press release include non-GAAP financial measures. Such information is provided as additional information and not as an alternative to Catalyst’s financial statements presented in accordance with the U.S. generally accepted accounting principles (GAAP). These non-GAAP financial measures are intended to enhance an overall understanding of Catalyst’s current financial performance. Catalyst believes that the non-GAAP financial measures presented in this press release provide investors and prospective investors with an alternative method for assessing Catalyst’s operating results in a manner that Catalyst believes is focused on the performance of ongoing operations and provides a more consistent basis for comparison between periods.

The non-GAAP financial measure in this press release excludes from the calculation of net income (i) the expense associated with non-cash, stock-based compensation, (ii) depreciation expense, and (iii) the provision for income taxes.
