Shares in Lexar Media Inc plunged 30.87% to $8.76 Friday despite first-quarter figures where net income rose 127% to $9.4m after revenue more than tripled to $161m. What scared the market was not only lower profit than expected, but a forecast of second-quarter price declines.

Though CEO Eric Stang forecast that second-quarter revenue would rise on a sequential basis by 18% to $190m, he only expects breakeven to slightly positive net income. For the year as a whole, the Fremont, California-based company expects revenue to nearly double and earnings per share to be $0.60.

Indications of problems for the sector came earlier when rival flash memory maker Sandisk Corp also revealed an impressive set of first-quarter figures with net income up 154.9% at $67.3m after revenue rose 121.8% to $386.9m.

However, Sandisk CEO Eli Harari forecasts lower margins as it planned early price reductions averaging about 20%. This was designed to drive demand for its 256-megabyte memory products and speed retail consumer market interest in its 512-megabyte cards, focused primarily on its high-capacity products.

Lexar’s Stang acknowledged the company as in a battle, and said Sandisk’s move was not driven by industry conditions. We won’t sit by and let others cut price against us, he said.
