Castlelake LP, a global alternative investment firm, has completed the final closing of its Castlelake Aviation IV Stable Yield LP with a total of $1.6 billion in capital commitments.

The fund received commitments from a group of repeat and first time investors from a spectrum of institutions like pensions, sovereign funds and endowments. The fund is the firm’s fourth aviation fund and represents its largest to date. The fund will focus on investments across high quality, younger mid-life aircraft and related aviation assets and has made use of $830 million across 13 transactions and 65 aircraft.

“We are grateful for the warm reception the Fund received from diverse global institutions and believe that it reflects Castlelake’s decades of experience navigating aviation investments across cycles, including through the most recent disruption caused by COVID-19,” said Rory O’Neill, managing partner and CEO of Castlelake. “We believe the current aviation market provides many compelling opportunities in which our exceptional team will be able to deploy capital.”
