Catalyst Pharmaceuticals Announces $40 Million Share Repurchase Program

CORAL GABLES, Fla., March 22, 2021 (GLOBE NEWSWIRE) -- Catalyst Pharmaceuticals, Inc. (Catalyst) (Nasdaq:CPRX), a commercial-stage biopharmaceutical company focused on developing and commercializing innovative therapies for people with rare debilitating, chronic neuromuscular and neurological diseases, today announced that its Board of Directors has authorized the repurchase of up to $40 million of shares of Catalyst's outstanding common stock.

"This share repurchase program reflects our confidence in the long-term outlook for the Company, including our ability to continue to generate strong cash flow," said Patrick J. McEnany, the Company's Chairman and Chief Executive Officer. "We believe that our strong balance sheet, earnings power and borrowing capability have us well-positioned to successfully execute both on our recently announced strategic initiative to expand our product and pipeline portfolio of therapies to treat other rare diseases and on this share repurchase program. We believe that executing on both of these objectives will help drive stockholder value."

Catalyst expects to make share repurchases at the discretion of management from time to time in the open market, depending on market conditions, or through privately negotiated transactions, subject to the requirements of the Securities Exchange Act of 1934, as amended, and related rules. The timing and amount of any shares purchased on the open market will be determined based on Catalyst's evaluation of market conditions, share price and other factors. The program does not obligate Catalyst to purchase any shares, and the program may be modified, suspended or terminated at any time and for any reason. No shares will be purchased directly from directors or officers of Catalyst as part of the share repurchase program.

Catalyst plans to use existing cash on hand to fund the share repurchase program.
