Gibson, Dunn & Crutcher is representing Prime Communications of Sugar Land in its pending $700 million purchase of GameStop Corp.’s Spring Mobile business. GameStop, based in Grapevine, is using Pepper Hamilton on the deal.

GameStop announced Nov. 21 that it entered into a definitive agreement to sell the Spring Mobile business, which owns and operates 1,289 AT&T wireless stores, to Prime Communications, which is the largest privately held A&T retailer in the country. GameStop is a global video game, consumer electronics and wireless services retailer.

The transaction is expected to close during the fourth quarter, subject to customary regulatory approvals and closing conditions.

Jeff Chapman, an M&A partner in Dallas, leads Gibson Dunn’s team on the acquisition. Others are partner Jonathan Whalen of Dallas for representation and warranty insurance matters; partner David Sinak of Dallas for tax matters; partner Darius Mehraban of New York for finance matters; partner Michael Collins of Washington, D.C., on employee benefits matters; and partner Richard Parker of Washington, D.C., for antitrust matters.

The Pepper Hamilton team for GameStop is led by partners Michael Friedman, Joan Arnold and Brad Boericke, all of Philadelphia.
