Press Release

HOUSTON, Texas - August 02, 2016 - KBR, Inc. (NYSE: KBR) announced today that in a decision in ongoing litigation involving COMMISA, a subsidiary of KBR, the United States Second Circuit Court of Appeals affirmed a judgment in excess of $465 million for COMMISA against PEMEX Exploracion y Produccion (PEP).

This positive result follows a decade of litigation involving two offshore natural gas treatment, processing and reinjection platforms which COMMISA built for PEP, platforms which have been working and in use by PEP since 2004 but for which COMMISA was never fully compensated.

"We are pleased the Court affirmed this substantial judgment for KBR's subsidiary COMMISA, an amount long overdue for work performed decades ago," said Stuart Bradie, President and CEO of KBR. "This ruling represents another step closer to finally resolving this protracted dispute. While PEP may seek rehearing or apply to the U.S. Supreme Court for review, KBR believes this decision moves us much closer to final resolution. We look forward to the day when we can finally put this matter behind us."

KBR's trial team was led by Richard Marooney with King & Spalding LLP in New York. KBR's appellate team was led by Paul Clement of Bancroft PLC in Washington DC. Both teams were ably supported by many others at both firms. About KBR, Inc.
