Telecommunications service integrator Tyto Athene on Wednesday said it has agreed to acquire the defense information technology (IT) services business of AT&T [T] in a deal that will add scale and a number of contractive vehicles.

Terms of the deal, which is expected to close in late March or early April, were not disclosed.

AT&T’s Government Solutions, Inc. (GSI) business includes the company’s DoD IT professional services business and other contracts.

Tyto said that GSI supports the Army’s Unified Communications program, the Space Force cyber defense mission, the Air Force Advanced Battle Management System, Navy 911 communications, DoD-wide 5G experimentation and testing, and other critical missions. The contracts GSI brings to Tyto include the General Services Administration’s (GSA) Alliant 2 for federal IT solutions, the Army’s RS3 C4ISR services vehicle, the Army’s Information Technology Enterprise Solutions-3 Services, the Navy’s SeaPort-NxG, and the GSA’s MEGASTAR for scientific and technical intelligence support services.

Tyto, a portfolio company of the private equity firm Arlington Capital Partners (ACP), expects the acquisition to help it meet evolving national defense requirements for digital transformation and joint all-domain operations.

Tyto was created in 2018 when ACP acquired the government solutions division of Black Box Corp. and renamed the business. Tyto in 2019 acquired Island Information Technology Consultants, adding unified communications solutions for the intelligence community.

Tyto is a systems integrator providing design, installation, and support of voice, data and security networks for federal civilian agencies, DoD, state and local governments, first responders and other organizations in the U.S. and globally.

The contract vehicles Tyto will gain through the acquisition “will provide us new ways to contract with our customers,” Chris Meilhammer, president and chief operating officer of Tyto, said in a statement. “We will continue to be poised to benefit from the secular tailwinds of the U.S. government investment strategy in legacy IT modernization and cyber security efforts. Tyto looks forward to teaming with AT&T to identify and pursue opportunities in the DoD and beyond.”

Following the acquisition, Tyto said it will have about 1,200 employees with 18 offices in the U.S. and worldwide.
