The company reported revenue of $1.18 billion for the second quarter of 2010, up 61% year over year. SanDisk also maintained excellent gross margins thanks to strong memory pricing and successful cost-cutting efforts. In response to this news we have increased the Trefis estimate for SanDisk's stock price from $43.70 to 50.21. Our analysis follows below. Sandisk sells memory cards to a number of original equipment manufacturers (OEMs). The OEM business grew 181% from the year-ago quarter, with unit volume more than doubling during the same period. The OEM business is expected to remain strong for the rest of the year, driven by new product cycles from manufacturers of smartphones, tablets, e-book readers and other mobile Internet devices that use flash-based storage solutions. SanDisk expects strong demand for memory cards from manufacturers of tablet devices that compete with Apple's ( AAPL) iPad. The company also announced a joint venture with Toshiba to manufacture flash memory at Fab 5, a new facility at Toshiba's memory production facility in Mie Prefecture, Japan. We estimate that memory cards for mobile phones constitute approximately 43% of SanDisk's share value. Sandisk sells mobile memory cards to both OEMs and retail customers. Retail demand has been particularly strong in Asian markets and seems likely to remain brisk for the rest of 2010. We expect SanDisk's share of the global mobile phone flash memory market to reach 32.5% by the end of the Trefis forecast period.
