Catalyst Pharmaceuticals Reports Positive Momentum in Second Quarter 2023

Reaffirms Full Year 2023 Total Revenue Guidance of Between $375 Million and $385 Million

Forecasts FIRDAPSE^® 2023 Net Product Revenue Guidance of Between $245 Million and $255 Million, an Increase of 17% YoY

Forecasts FYCOMPA^® 2023 Net Product Revenue of Approximately $130 Million for 11 Months

Reaffirms Full Year 2023 Non-GAAP Net Income Forecast of Between $195 Million and $205 Million

CORAL GABLES, Fla., June 01, 2023 (GLOBE NEWSWIRE) -- Catalyst Pharmaceuticals, Inc. ("Catalyst" or "Company") (Nasdaq: CPRX) today reported positive momentum for the second quarter of 2023 and reaffirmed its full-year 2023 total revenue guidance of between $375 million and $385 million, representing a 75% to 80% increase in total revenues compared to 2022. The Company also reaffirmed its forecast for the full year 2023 non-GAAP net income to be between $195 million and $205 million. This guidance reflects Catalyst's confidence in sustained organic revenue growth for FIRDAPSE^® combined with synergistic net product revenues derived from sales of FYCOMPA^®, a second commercial product for which the Company acquired U.S. rights on January 24, 2023.

"As recently reported, the ongoing execution of our commercial strategy drove record results for the first quarter of this year as viewed against all metrics," said Patrick J. McEnany, Chairman and CEO of Catalyst. "As we advance into the second quarter of 2023 with sustained momentum, we are on track to meet our guidance which is supported by our exceptional financial performance and strategic accomplishments. Given our recent acquisition of FYCOMPA and the related increase in amortization expenses of intangible assets, we believe that the non-GAAP financial measures that we are currently providing in our financial results press releases provide greater transparency and should assist in better understanding and assessing Catalyst's business as well as how we manage our business internally and set operational goals. We believe the benefits from our diversified and complementary product portfolio will continue to generate strong free cash flow as we continue to advance on our growth initiatives to drive sustainable growth and deliver value for our shareholders."

Financial Guidance for Full Year 2023

The Company's 2023 financial guidance reflects considerations reported in its Form 10-Q filed on May 10, 2023, as well as its performance to date in the 2023 second quarter. Based on these considerations, the Company believes that it is now in a position to provide more detailed financial guidance for the full year 2023 on both a GAAP and a non-GAAP basis.

• Full-year 2023 total revenues are forecasted to be in the range of between $375 million and $385 million, representing a 75% - 80% increase in total revenues as compared to 2022.
  
  
• FIRDAPSE^® net product revenues for 2023 are forecasted to be between $245 million to $255 million, a 17% increase from the mid-point year over year.
  
  
• FYCOMPA^® net product revenues for 2023 are forecasted to be approximately $130 million for approximately 11 months of sales. The Company's acquisition of this product closed on January 24, 2023.
  
  
• Cost of goods sold is expected to be approximately 13% of aggregate net product revenues.
  
  
• GAAP operating expenses are forecasted to be between $175 million and $185 million in 2023. This includes (i) approximately $57 million of expenses directly related to our FYCOMPA program, which includes approximately $10.3 million for one-time transition services fees ($6.7 million in Q1-2023 and estimated $3.6 million in Q2-2023), and (ii) amortization of intangible assets of approximately $32 million (approximately $8.5 million per quarter for the second, third and fourth quarter of 2023).
  
  
• GAAP net income before income tax for 2023 is forecasted to be between $150 million and $155 million.
  
  
• Non-GAAP net income for 2023 is forecasted to be between $195 million and $205 million.
  

This forecast does not account for the impact on the forecasted results of any future acquisition transactions that Catalyst may complete in 2023. Further, non-GAAP net income for 2023 excludes from GAAP net income stock-based compensation, depreciation, amortization, and income taxes. Finally, key guidance assumptions included in these projections reflect a continued recovery in macroeconomic and healthcare activity throughout 2023 and no change to the current COVID-19 environment.
