What Castlelake does

Castlelake, L.P. is a global institutional alternative investment firm founded in 2005 and headquartered in Minneapolis, Minnesota. The firm manages approximately $38 billion in assets under management on behalf of more than 200 institutional investors, including pensions, sovereign wealth funds, endowments, financial institutions, and insurance companies. Castlelake specializes in asset-based private credit, with investment activities concentrated across three strategy pillars: Aviation (aircraft leasing and lending, including the CLAS aviation ABS program and the Merit AirFinance lending subsidiary launched in August 2025), Specialty Finance (consumer credit, small/medium business finance, and residential mortgage, delivered through funds, separately managed accounts, and forward-flow agreements with named originators such as Upstart and Pagaya), and Real Assets (transitional commercial real estate, infrastructure, and non-performing loans). Capital is delivered through closed-end investment funds (including Castlelake Aviation V Stable Yield L.P., which raised over $2 billion in March 2025), separately managed accounts, and structured private placements, and is sourced through both direct institutional sales and the firm's September 2024 strategic partnership with Brookfield Asset Management, which acquired a 51% interest in Castlelake's fee-related earnings. The firm operates from eight offices across North America (Minneapolis, New York, Dallas), Europe (London, Madrid, Dublin), the Middle East (Dubai), and Asia (Singapore), and employs approximately 250 professionals, including 90 investment professionals.

Revenue model

1. Asset-based private credit investment management: Recurring asset-based investment management fees earned on approximately $36–38 billion of assets managed on behalf of a diversified global institutional investor base (more than 200 institutional investors), delivered through closed-end investment funds, separately or individually managed accounts and other private placement formats. Brookfield Asset Management acquired a 51% interest in Castlelake's fee-related earnings in September 2024.
2. Aviation leasing and lending income: Income generated from on- and off-balance-sheet finance to airlines and other aviation asset owners, including aircraft leasing, secured lending and asset-backed securitization issuance (CLAS 2021-1, CLAS 2025-1/2/3); Castlelake has deployed more than $5 billion to airlines and leasing companies since 2020 and secured $1 billion in long-term aviation financing in 2024 to acquire more than 60 aircraft assets leased to ~30 airlines worldwide.
3. Specialty finance forward-flow and loan purchase income: Revenue generated through asset-based private credit facilities, forward-flow loan purchase agreements and securitization economics with consumer, SME and mortgage originators (e.g., $1.5 billion forward-flow with Upstart, $500 million auto forward-flow with Pagaya, $4 billion Upstart commitment history, $2.5 billion prior Pagaya personal-loan purchases, £70m TradeBridge facility, £95m Equifinance facility, £250m LendInvest partnership, up to $2 billion Invictus partnership, €1 billion Niam Credit partnership, $250m Pulse funding, €125M GoByBike/Santander facility).
4. Capital markets and securitization structuring fees: Income from Castlelake's in-house capital markets capabilities including private securitization technology, structuring and ratings expertise used to originate and rate aviation ABS, residential mortgage securitizations and other asset-backed transactions for its own funds and counterparties.
5. Origination platform ownership economics: Returns from majority ownership stakes in specialty finance and aviation sourcing platforms (Eastview and Lendmarq via Resfin Partners acquisition in April 2026; four other owned sourcing platforms) and strategic operating subsidiaries such as Merit AirFinance, providing programmatic origination and balance-sheet exposure to investment opportunities.
6. Performance-related earnings: Performance fees and carried interest on closed-end funds, retained by Castlelake's founders and professionals; Castlelake retains majority ownership of its performance-related earnings following the Brookfield strategic partnership transaction.

Core offering

Castlelake is a global alternative investment firm managing approximately $38 billion in assets under management on behalf of more than 200 institutional investors. The firm provides asset-based private credit capital solutions across three strategy pillars (Aviation, Specialty Finance, and Real Assets), deploying capital through closed-end investment funds, separately managed accounts, and forward-flow loan purchase agreements, and operating owned origination platforms (Eastview, Lendmarq) and a dedicated aviation lending subsidiary (Merit AirFinance).

Product overview

Castlelake operates as a unified global alternative investment management platform with a modular strategy architecture comprising five core investment strategies (Aviation Leasing & Lending, Consumer Finance, Small/Medium Business Finance, Residential Mortgage, Commercial Mortgage) grouped under three top-level strategy pillars (Specialty Finance, Real Assets, Aviation). The platform combines (a) direct investment funds and separately managed accounts, (b) proprietary in-house origination platforms acquired via majority stakes (Eastview, Lendmarq, Resfin Partners) and joint ventures (Merit AirFinance as an aviation lending operating subsidiary, Itasca MGA and Itasca Re as insurance/reinsurance vehicles, the Redwood Trust Sequoia joint venture for prime jumbo loans), and (c) a recurring asset-backed securitization issuance program (CLAS series) used to finance aircraft pools. Castlelake also operates as an opportunistic acquirer in distressed aviation situations, including disclosed possible takeover offers for easyJet plc and Spirit Airlines. The firm is a strategic partner of Brookfield Asset Management following Brookfield's September 2024 acquisition of a 51% interest in Castlelake's fee-related earnings.
