SanDisk shot down a $5.85bn all-cash unsolicited bid from Samsung Electronics, saying the bid by the South Korean electronics giant doesn’t reflect the full value of flash memory provider. Despite the rejection, SanDisk shares surged 39%, closing at $20.92. Samsung bid $26 for each share. Last October, SanDisk shares changed hands above $50. Samsung made its offer public after saying four months of talks had come to nothing. SanDisk posted a loss and a sales decline last quarter. The company projects revenue for the current quarter will drop about one-quarter from last year. Included in SanDisk’s revenue is several hundred million dollars that Samsung pays SanDisk each year for patent royalties.
