GameStop filed with the SEC to seek shareholder approval to increase its authorized common shares to 2.5 billion from 1 billion, adding 1.5 billion shares if approved. The proposal is one of five items scheduled for the company’s July annual meeting and is presented as a move that could improve financial flexibility. The filing may also support a renewed bid for eBay after an earlier rejection, although the source does not specify how any additional shares would be used.
