July 16 (Reuters) - SanDisk Corp gave a current-quarter revenue forecast that was below Wall Street's estimate, warning that it would be unable to the meet the booming demand for solid-state drives and memory chips, and its shares fell 9 percent in extended trading.
The company also reported second-quarter profit and revenue that barely beat analysts' expectations, disappointing investors who have seen the company blow past Wall Street's forecasts for at least the past eight quarters.
That streak was threatened by the company's third-quarter revenue forecast of $1.68 billion to $1.73 billion, which was short of analysts' average estimate of $1.74 billion, according to Thomson Reuters I/B/E/S.
SanDisk's growing focus on high-end solid-state drives, or SSDs, helped offset volatile prices for memory chips, powering the company's stellar results and, since late March, its stock's rise to life-high levels.
However, the company's increasing focus on cost control has dented its ability to expand capacity to keep up with industry demand, said Betsy Van Hees, an analyst at Wedbush Securities.
"They find themselves in a situation in which they were a couple of years ago, when in the industry the supply-demand is balanced and they are supply constrained," she said.
SanDisk's cost cutting target would likely be around the middle to "somewhat" higher than the middle of its 15-25 percent forecast for the year, Chief Financial Officer Judy Bruner said on a conference call.
The company is increasingly using its memory chips in the SSDs that it sells directly, but Bruner said gross margins on these embedded products were "somewhat below" the corporate average, which would dent gross margins going forward.
SanDisk said it continues to expect adjusted gross margins of 47-49 percent in the current quarter. Gross margins rose to 48 percent in the second quarter from 47 percent a year earlier.
The company's revenue from SSDs comprised about 29 percent of the total revenue in the second quarter ended June 29, up from 16 percent a year earlier.
SanDisk, which counts Facebook Inc and Apple Inc among its customers, said total revenue rose 11 percent to $1.63 billion.
Net income rose 4.6 percent to $273.9 million, or $1.14 per share. Excluding one time items, SanDisk earned $1.41 per share.
Analysts had expected a profit of $1.39 per share on revenue of $1.60 billion, according to Thomson Reuters I/B/E/S.
Shares of the company closed at $107.83, after hitting a life-high of $108.77 on Nasdaq on Wednesday. The stock fell to $97.68 in extended trading.
