Sony has officially made an acquisition offer to Tamron, the lens maker confirmed today. Tamron says that Sony’s proposal outlines a series of transactions that will result in Sony owning all shares of Tamron, establishing it as a wholly owned subsidiary company. Given that Tamron has established a special committee to consider Sony’s proposal, it is immediately evident that Tamron is not outright denying Sony’s purchase attempt. If Tamron became a wholly owned subsidiary of Sony, Sony would have complete and total control over all of Tamron’s operations. Tamron’s shares surged nearly 29 percent during Japanese trading overnight following the company’s statement.
