"We are excited to partner with BXCI, whose scale and long-term capital commitment will accelerate the growth of our asset management business," said Austin C. Willis, CEO of WLFC. "Blackstone is a leader in asset-based credit, and their investment demonstrates the strength of our position in aircraft engine leasing and their belief in our ability to generate attractive returns through disciplined asset selection and active management."

Scott Flaherty, CFO of WLFC, added "the Blackstone relationship provides further capital diversification to the Willis platform. We are excited about this new relationship and the growth opportunities this brings to our business."

"Willis is a leading lessor of commercial aircraft engines and brings unparalleled technical expertise, deep customer relationships and a proven track record," said Aneek Mamik, Senior Managing Director, Blackstone Credit & Insurance. "This opportunity is consistent with BXCI's objectives of building programmatic, differentiated origination in large addressable markets with a focus on hard assets and strong downside protection."
