Richardson, Texas — June 30, 1997 — Cyrix Corporation (NASDAQ: CYRX) today announced that, based on preliminary results, the Company now expects revenue levels to be significantly below the $75.6 million reported in the first quarter this year, but much stronger than the second quarter of 1996. The original goal of revenues being flat or slightly up from the first quarter of 1997 will not be met primarily due to weak overall demand and significant pricing pressure on the non-MMX™ 6x86™ processor. This revenue shortfall will produce a loss in the second quarter, but the company does expect to be around the break-even point for the first half of 1997 versus the large loss posted in the same time period last year.

"We are disappointed that Cyrix will not reach our goal of profitability in the second quarter," said Jay Swent, Cyrix’s chief financial officer and acting chief executive officer. "We were however, able to meet two of our three major goals: First, we successfully introduced and shipped more than 35,000 MMX-enhanced 6x86MX™ processors; and second, market acceptance of the MediaGX™ processor continued to meet or beat our expectations. Managing the transition of the non-MMX 6x86 processor will remain a top priority for us in the third quarter. Looking forward, our current product lineup positions us well to drive both revenue and profit performance in the second half of 1997."
