ISSI ANNOUNCES SECOND QUARTER FISCAL YEAR 2003 RESULTS
Improved Financial Performance

     Santa Clara, Calif.—April 24, 2003—Integrated Silicon Solution, Inc. (Nasdaq: ISSI) today reported financial results for the second fiscal quarter ended March 31, 2003.

     Revenues in the second quarter of fiscal 2003 were $22.3 million, compared with $16.6 million in the second quarter of the prior year and $21.0 million in the quarter ended December 31, 2002. The Company reported a net loss for the March 2003 quarter of ($7.0) million or ($0.25) per diluted share, compared with a net loss of ($12.7) million or ($0.46) per diluted share in the December 2002 quarter, and a net loss of ($10.6) million or ($0.39) per diluted share in the March 2002 quarter. The Company ended the March 31, 2003 quarter with cash and short term investments of $66.7 million.

     “Revenue in the recent March quarter shows a 34% growth over March 2002, and 6% over the recent December quarter,” said Jimmy Lee, ISSI’s Chairman and CEO. “We are hopeful that these trends will continue. The strongest market segment for ISSI is currently consumer electronics, a market segment that we targeted after the last up-cycle. Consumer electronics represented about 50% of our revenue in the March 2003 quarter, mostly in Asia.”

     During the March 2003 quarter, the Company took additional steps to cut expenses, including a reduction in force of 15% of the worldwide employee base. Operating expenses dropped from $10.5 million in the December 2002 quarter to $9.5 million in the March 2003 quarter.

     “We will continue to seek ways to reduce our operating expenses,” said Gary Fischer, ISSI’s President and COO. “Our expenses for the quarter ending in June 2002 totaled $12.2 million. The March 2003 quarter reflects a 22% reduction in expenses from June 2002, so we feel we are definitely making good progress.”
