Tech Data Corp., a technology and software distributor and Tampa Bay's largest public corporation by revenues, plans to expand its headquarters. Based just north of St. Peter-Clearwater International Airport, the company says it will build a 45,000-square-foot facility adjacent to its 240,000-square-foot office building. The company on Friday said it is working with local officials to seek approval for the additional space. The new facility will accommodate office and meeting space, the company stated, "allowing us to operate more efficiently into the foreseeable future." The company employs more than 9,000 with just over 1,700 at its headquarters.
