Boca Raton, FL– July 18, 2019 – AE Industrial Partners, LP (“AEI”), a private equity firm specializing in
Aerospace, Defense & Government Services, Power Generation, and Specialty Industrial markets,
announced today that it has signed a definitive agreement to acquire Columbia Helicopters
(“Columbia” or the “Company”), a leading provider of heavy-lift rotorcraft services with extensive
manufacturing and MRO capabilities. Columbia’s CEO Steve Bandy will remain in his role, while
majority owner Nancy Lematta will retain a significant ownership position in the Company. Terms of

industry pioneer Wes Lematta and based in Aurora, Oregon, Columbia holds many aviation
authorizations, including a Department of Defense (DoD) Commercial Airlift Review Board (CARB)
certification, which allows the Company to perform outsourced military transport, among other
mission-critical operations.

“This is an exciting new phase of evolution for Columbia,” said Mr. Bandy. “We have always taken
pride in our dedicated people and how they deliver inspired solutions to our customers. This new
partnership supports our vision of growth and diversification. With AEI’s support and experience,
Columbia’s commitment to safety and operational excellence and, above all else, our people—we
are positioned for even greater success well into the future.”

“Columbia is a clear industry leader with a storied history, offering a unique and differentiated
platform, and a strong track record of best-in-class aviation services,” said Kirk Konert, a Principal at
AEI. “AEI is excited to support the Company, as we believe there is a significant opportunity to build
on the capabilities that Columbia has developed over the last 60 years, and expand into new markets
and services. With the support of Columbia’s outstanding management team, we look forward to
helping the Company take the next step in its evolution.”
