Triumph Group, Inc. (the “Company”) reports that, on December 22, 2016, Triumph Aerostructures, LLC, a wholly owned subsidiary of the Company (“Triumph Aerostructures”), initiated litigation against Bombardier Inc. (“Bombardier”), a customer of Triumph Aerostructures, in the Quebec Superior Court, District of Montreal. The lawsuit relates to Bombardier’s failure to pay to Triumph Aerostructures certain non-recurring expenses incurred by Triumph Aerostructures during the development phase of a program to which Triumph Aerostructures agreed to design, manufacture, and supply the wing and related components for Bombardier’s Global 7000 business aircraft. The lawsuit seeks a monetary award of approximately US$340,000,000 (or CAD $455,000,000) resulting from Bombardier directed changes to the original wing requirements for the Global 7000 program, as well as Bombardier’s, delays, disruptions, acceleration and interference in connection with its contract with Triumph Aerostructures. In the meantime, Triumph Aerostructures continues to support the Global 7000 program and to seek a resolution of its disputes.
