GTSI Participates With AT&T on $20 Billion, Multiple-Award GSA Networx Enterprise Contract

GTSI Corp.®, an enterprise solutions and services provider, (NASAQ: GTSI) will provide a range of information technology services to federal government agencies and will serve as a subcontractor to AT&T Government Solutions, a business unit of AT&T, Inc. AT&T was awarded a Networx Enterprise contract by the U.S. General Services Administration (GSA).

Networx Enterprise is a companion contract to Networx Universal, awarded to the AT&T team in March. Under the Networx Enterprise contract, GTSI will work with AT&T to compete for Internet Protocol (IP), optical and wireless services to specific geographic regions served by federal government agencies. GTSI and AT&T will compete for task orders for telecommunications, networking, and related services. The Networx contracts allow for the AT&T team to offer innovative solutions to more than 135 federal agencies.

“The combined wins of both Networx Universal and now Networx Enterprise will provide GTSI and the AT&T team with the largest telecommunications contracting opportunity ever,” said Jim Leto, GTSI’s President and Chief Executive Officer. “GTSI is fully engaged with the AT&T team and anticipates delivering new telecommunications solutions for our federal government customer through a technology lifecycle management approach.”

The AT&T Networx team brings together industry-leading networking and IT capabilities, which also includes Northrop Grumman Information Technology of McLean, Va.; EDS of Herndon, Va.; SRA International, Inc., of Fairfax, Va.; Bechtel National of Frederick, Md.; and Global Crossing of Florham Park, N.J.

Networx Enterprise is an Indefinite Delivery – Indefinite Quantity (IDIQ) contract with a potential value of $20 billion over the next 10 years. Networx will replace the expiring GSA FTS2001 and FTS2001 Crossover contract vehicles. The Networx contract gives AT&T, GTSI, its teammates, and others the right to compete for specific task orders within the scope of the Networx Enterprise contract. Networx Enterprise does not require contractors to provide services to as many locations.
