HOUSTON - (February 23, 2018) - KBR, Inc. (NYSE: KBR) announced today it has entered into a definitive agreement to purchase Stinger Ghaffarian Technologies, Inc. (SGT) a leading provider of technology solutions, engineering services, mission operations, scientific and IT software solutions in the Government Services market.

SGT has a distinguished heritage delivering technology solutions and services to the U.S. government for space programs, national security and civilian operations.
The addition of SGT solidifies KBRwyle's position as an established leader in human space exploration and opens up significant new opportunities in both civil and military space. The acquisition will also strengthen KBR's support for strategic clients and enhance our position for opportunities in the national security and commercial space markets.

NASA's recent budget requests prioritizing growth in deep space exploration, science, low earth orbit and spaceflight operations and its emerging strategy to potentially utilize public-private partnerships or other commercialization to support the International Space Station (ISS), provides validation for KBR's strategy across NASA which is directly supported by the acquisition of SGT.

This strategic acquisition of SGT builds on previous acquisitions of Wyle and HTSI and will be an important accelerator to KBR's strategy to increase technology and mission capabilities. SGT is only the 2nd company in the United States and the 22nd in the world to hold the CMMI Institute's Capability Maturity Model Integration (CMMI)^® Level 5 for Development and Services.

"SGT is a great company with very talented people and is the right fit for us as we continue to grow our Government Services portfolio and position ourselves to expand into new areas in line with our strategy," said Stuart Bradie, KBR President and CEO. "With our combined best in class capabilities and shared position for innovation and performance, we can capitalize on revenue synergies in a market with strong fundamentals.

"We are excited to bring SGT into the KBRwyle family," Bradie said. "This is a strong cultural fit. Like KBR, SGT is a people company that operates with integrity and delivers strong results by putting customers and employees at the forefront of everything they do."

KBR expects SGT to become a business unit within KBRwyle and will maintain SGT's current management structure in order to preserve a continuity of services to customer during transition.

"This transaction creates an exciting future," said Dr. Kam Ghaffarian, President and CEO of SGT. "As a combined entity, we will be able to bring powerful capabilities and solutions to the marketplace and broaden our service offerings for our existing customers. The alignment of the strong employee focused cultures and the combined business synergies makes this an ideal situation."

The transaction is expected to be accretive to adjusted earnings per share in the first full year after closing, excluding non-recurring transaction costs. The transaction has been unanimously approved by the KBR Board of Directors and is subject to certain regulatory approvals and customary closing conditions.
