Dear [Supplier]:

I am pleased to share some exciting news about Hexcel. As you may have heard, Hexcel and Woodward have agreed to combine to create a premier integrated systems provider serving the aerospace and industrial sectors. The new company, which will be named Woodward Hexcel, will focus on technology-rich innovations to deliver smarter, cleaner, and safer customer solutions.

Today, Hexcel customers expect us to deliver innovative solutions to make aerospace and industrial products stronger, lighter and tougher. As a combined company, we will be able to accelerate our technology investments to advance this work and create greater benefits and growth opportunities than either company could have achieved alone. The future of flight and energy efficiency will be defined by next-generation platforms delivering lower cost of ownership, reduced emissions, and enhanced safety – and a combined Hexcel and Woodward will be at the forefront of this evolution, able to support our customers’ evolving needs.

Building on each company’s strong existing positions on best-in-class product platforms, the combined company will have greater depth and balance of customer relationships across the aerospace and industrial sectors, with significant opportunities for cross-selling and to enhance customer relationships. Partners like you remain fundamental to our business, and we look forward to leveraging the resources of the combined Woodward Hexcel to strengthen that partnership.

The transaction is expected to be completed in the third calendar quarter of 2020. Until then, Hexcel and Woodward will continue to operate as two independent companies. During this transition period, we expect to continue to work with you as we always have, and your Hexcel contacts and supply agreements remain the same. Upon close of the transaction, we expect a seamless transition for all of our stakeholders, including you, our valued business partner.

On behalf of the Hexcel team, thank you for your continued support. We are incredibly excited about what we can accomplish by uniting these two premier companies with similar values, cultures, and operating philosophies. We value our relationship with your organization and hope you share our enthusiasm about our future.
