ALPHA INDUSTRIES Announces Expectations for Fourth Quarter.

WOBURN, Mass.--(BUSINESS WIRE)--March 2, 1999--ALPHA INDUSTRIES, INC. (NASDAQ:AHAA) today announced that it expects to report earnings per share of approximately $0.51 for the fourth quarter ending March 28, 1999, including $0.20 per share of tax benefit resulting from the expected use of net operating loss tax carryforwards. These earnings, excluding the tax benefit, are in line with analysts' estimates. The company also announced that it expects revenues for the quarter of between $33.5 and $34.0 million, slightly below analysts' estimates.

Tom Leonard, President and Chief Executive Officer of Alpha, stated, "Revenues for the quarter will be slightly lower than our expectations, because one of our packaging subcontractors in Asia experienced a temporary production interruption and two non-handset customers pushed out their deliveries by one quarter.

"Alpha will complete this fiscal year in March with the highest sales and profit levels in the company's history. Orders to date for shipment in the June quarter are robust, especially in the high-volume Wireless Semiconductor Products, so we are confident that our sales and earnings for the June quarter will be in line with analysts' expectations."
