Highlights

Matt Hoesley, a 21-year veteran of Altavair, will become the aircraft leasing and trading firm's CEO and President on January 1, 2027, as co-founder Stephen Rimmer transitions to executive chairman after more than two decades running the business.

Rimmer co-founded Altavair in 2003, originally as Guggenheim Aviation Partners, and brings more than 40 years of commercial aviation experience to the chairman role. Before Altavair, he founded Curtis Power Company, an early commercial engine leasing operation that he sold to General Electric in 2001.

Hoesley joined the firm in 2005. His promotion follows a leadership reorganization that also elevates Dimitrios Kotinis to Chief Commercial Officer, a role that will encompass marketing, trading, pricing, risk, and capital markets functions, according to the company's announcement.

Who backs Altavair financially?

KKR has committed $1.4 billion in equity to Altavair, and KKR-managed vehicles have deployed more than $8 billion into aircraft leasing since 2018. Altavair has completed nearly $15 billion in commercial aircraft lease transactions with more than 80 airline customers across 50-plus countries. The firm maintains offices in Seattle, Dublin, and London.

The transition is scheduled to take effect January 1, 2027.
