EXHIBIT 99.1 CATALYST SEMICONDUCTOR REPURCHASES 1.5 MILLION SHARES FROM INVESTOR IN PRIVATE TRANSACTION SUNNYVALE, CALIF., APRIL 29, 2002--Catalyst Semiconductor, Inc. (NASDAQ:CATS) (or the "Company") today announced that it has completed the repurchase of 1.5 million shares of its common stock held by Elex N.V., a Belgian holding company, in a private transaction. Prior to this repurchase, Elex owned approximately 29.7% of the Company's outstanding shares. Elex continues to hold another 4.0 million shares of Catalyst Semiconductor common stock. Mr. Roland Duchatelet, the Chairman and CEO of Elex, serves as a member of Company's Board of Directors. The stock transfer agreement entitled Catalyst Semiconductor to a five percent discount from the April 19, 2002 closing price of the Company's common stock listed on the Nasdaq SmallCap Market, and the repurchase was completed at $3.1255 per share. The company will convert the purchased shares to treasury stock, thereby reducing its shares outstanding to approximately 17 million out of 45 million authorized shares. "Last September, our board authorized the repurchase of up to 1.5 million shares of the Company's common stock in the open market and in negotiated transactions. Through the quarter ended January 31st, we had only repurchased 193,700 shares. Therefore, with approximately $29 million of cash and cash equivalents on hand, management and the board felt our assets were more than sufficient to fund the Company's operations and that this opportunity to repurchase a large block of our shares at a discount from the market price represented an attractive use of a portion of our excess cash. We believe that the resulting reduction in our capitalization will enhance value to the benefit of our stockholders," said Radu Vanco, Chairman and Chief Executive Officer.
