BTG Inc, the Fairfax, Virginia-based systems integrator, has signed a letter of intent to acquire STAC Inc, for $6.9m. BTG will acquire all the common stock of the 65-person company, expected to report $10m in revenues for its fiscal year ending in December 1998, and hopes to have the deal completed in November. STAC, also based in Fairfax, is an employee-owned analysis and software development company not related to the better known storage management and remote access software provider Stac Inc from San Diego, California. It was founded in 1994 to supply analytical services and software development support to US intelligence agencies, government agencies and commercial companies. BTG also concentrates on government and defense customers, although it also has commercial clients, and interests in cable internet. It sold off its federal government reseller division earlier this year in order to focus on services and support, and decided not to go ahead with a proposed acquisition of commercial networking company Micros-to-Mainframes Inc, citing financial considerations. It had bid $25m in cash and stock for the network integration firm (CI No 3,349).
