Press Release

HOUSTON (October 5, 2017) KBR, Inc. (NYSE: KBR) announced today that, through its global government services business KBRwyle, it will once again join the Association of the U.S. Army (AUSA) as co-lead sponsor of the Army Ten-Miler (ATM) race in Washington, D.C. on Sunday, October 8.

KBR has been a major sponsor of the ATM for 12 years. At the race, KBRwyle provides free event shuttles, water stations, pre-packaged meal boxes, and reunion areas where family and friends link up with runners. KBRwyle also sponsors the famous Hooah-Tent Zone where attendees interact with soldiers while enjoying the ATM experience and Wisconsin bratwursts, cooked and served by Rockland's BBQ restaurant in Arlington, Virginia.

The ATM is the third largest ten-mile race in the U.S. with an estimated attendance this year of 40,000 runners and spectators from around the world.

"KBRwyle is very pleased to partner with organizations like AUSA and the Army Ten-Miler to support soldiers and veterans from across the military," said Byron Bright, KBRwyle President.Ê "KBRwyle stands beside our troops supporting them in carrying out their important missions worldwide, and stands behind them and their families when they return home."

All proceeds from the ATM go to the U.S. Army's Morale, Welfare, and Recreation (MWR) program. The MWR program directly supports soldiers and their families worldwide by providing a variety of family, morale, welfare and recreation programs and services to enrich soldiers' and their families' lives culturally and creatively.
