ISSI (ISSI) Raises Second Fiscal Quarter Revenue and EPS Guidance

SAN JOSE, Calif., March 22 /PRNewswire-FirstCall/ — Integrated Silicon Solution, Inc. (Nasdaq: ISSI) today updated its financial guidance for the second fiscal quarter ending March 31, 2010. During the March quarter to date, the Company has experienced better than expected end market demand and pricing, primarily for its DRAM products. As a result, the company is increasing its revenue and margin guidance for the quarter. In addition, due to higher than expected new product mask costs and non-executive employee compensation, the Company now expects its operating expenses to be higher than previously expected. The Company also expects its net income and earnings per share to be higher than its prior guidance. ISSI’s updated guidance for the March quarter is as follows:

    --  Revenue to be between $54 million and $56 million compared to previous
        guidance of $48 million to $52 million.
    --  Gross margin to be between 34 percent and 38 percent compared to
        previous guidance of between 28 percent and 32 percent.
    --  Operating expenses to be in a range of $14.0 million to $14.6 million
        compared to previous guidance of $12.4 million to $13.0 million.
    --  Net income to be between $0.20 and $0.24 per fully diluted share
        compared to previous guidance of between $0.08 and $0.12 per share.

“Demand in all of our markets has further strengthened in the March quarter exceeding our original expectations as the DRAM market continues to experience increasing demand while DRAM supplies remain constrained,” said Scott Howarth, ISSI’s President and CEO. “Pricing for DRAM also improved helping to increase our gross margins and net income,” added Mr. Howarth.
