What Littlejohn & Co does

Littlejohn & Co. is a Greenwich, Connecticut-based integrated private equity and credit investment firm founded in 1996 that deploys capital across middle-market industrial and services companies in North America. The firm operates three synergistic strategies — Private Equity (buyouts, carve-outs, and growth investments), Credit (performing credit via its Wellfleet Credit Partners CLO franchise, which reached approximately $4.2 billion in assets under management following its tenth CLO), and Capital Solutions (structured equity to bridge gaps traditional capital cannot address) — under an explicit "all-weather" mandate executed across market cycles. With approximately $8 billion in regulatory assets under management as of September 30, 2024 (and approximately $9.0 billion per a March 2026 reference), 70+ employees including 45+ investment professionals, and an average partner tenure of roughly 20 years, Littlejohn positions itself as a long-duration, operationally engaged partner for families, founders, and management teams.

The firm's core operating model centers on an integrated Portfolio Support Group that delivers time-tested value creation playbooks to portfolio companies, with documented operational outcomes including Kaman Distribution Group EBITDA growth of 50%+ during COVID, Valcourt completing 20+ acquisitions during Littlejohn's hold and serving 16,000+ properties, Milrose Consultants growing earnings more than 7x, and Motion Recruitment Partners doubling in size through M&A. The current active portfolio spans more than a dozen operating companies across building services (Valcourt, Pritchard Industries, Milrose Consultants), industrial distribution and automation (80/20, formerly Cook & Boardman minority stake), infrastructure services (Ardurra, RailPros, GDS Associates), specialty distribution (Lipari Foods, Imperative Logistics Group), healthcare talent and technology (AHSG), industrial safety (Total Safety, post-restructuring focused on North America), and residential HVAC/plumbing (United Comfort Group).

Littlejohn pursues a relationship-driven, proprietary deal sourcing model primarily through direct outreach and investment banking intermediary relationships — including Moelis, Houlihan Lokey, J.P. Morgan, Lincoln International, Baird, Harris Williams, Jefferies, AEC Advisors, Solomon Partners, Campbell Lutyens, and Stifel — supplemented by a single Greenwich office that the firm describes as "core to our culture and integrated investment strategy." Revenue is generated through private equity fund management fees and carried interest, CLO structuring/asset management fees from the Wellfleet credit franchise, capital solutions transaction-level economics, and continuation vehicle transaction fees (e.g., the May 2026 Valcourt continuation vehicle led by Carlyle AlpInvest). Terms are not publicly disclosed; investor access is handled bilaterally through the firm's investor relations function.

Revenue model

1. Private Equity Fund Management Fees & Carried Interest: Littlejohn raises private equity funds focused on middle-market industrial and services buyouts, carve-outs, and growth investments; revenue is generated via management fees on committed/invested capital and performance-based carried interest upon successful realization events.
2. Credit Strategy Revenue (Wellfleet Credit Partners): Performing credit business includes a CLO franchise (Wellfleet), with approximately $4.2 billion in AUM following the Wellfleet CLO X issuance. Revenue is generated through CLO structuring fees, asset management fees, and net interest income on managed credit assets.
3. Capital Solutions (Structured Equity): Littlejohn provides creative and flexible capital solutions to companies seeking to solve liquidity issues, finance acquisitions, refinance lenders, or fund growth initiatives, typically in the form of structured equity. These investments 'bridge a gap' that traditional equity or debt financing cannot address.
4. Continuation Vehicle Transactions: Littlejohn closes continuation vehicles (e.g., Valcourt Group anchored by Carlyle AlpInvest in May 2026) that provide optional liquidity to existing fund investors while allowing continued partnership and a fresh investment alongside CV investors. These transactions generate transaction-level fees and economics.

Core offering

Littlejohn & Co. is an integrated private equity and credit investor focused on middle-market industrial and services companies in North America. The firm executes an "all-weather" strategy across three synergistic strategies: Private Equity (buyouts, carve-outs, growth investments), Credit (Wellfleet Credit Partners CLO franchise), and Capital Solutions (structured equity). The firm partners with families, founders, and management teams to scale businesses through operational improvements and M&A, while providing tailored capital solutions that bridge gaps traditional equity or debt financing cannot address.

Product overview

Littlejohn & Co is an integrated private equity and credit investment firm — not a software/technology vendor — whose "products" are its three core investment strategies (Private Equity, Credit, and Capital Solutions) deployed across middle-market industrial and services companies in North America. The Private Equity strategy forms the firm's flagship offering, partnering with families, founders, and management teams to execute buyouts, carve-outs, credit, and capital solutions opportunities with an "all-weather" mandate. The Credit strategy operates through Wellfleet Credit Partners, the firm's performing credit business that issues CLOs backed by broadly syndicated senior secured loans. The Capital Solutions strategy provides structured equity to bridge gaps in companies' capital structures. Supporting these strategies is the Portfolio Support Group, an integrated operational team that works with portfolio companies to drive value creation. Under the Private Equity strategy, Littlejohn maintains a large portfolio of operating companies — including 80/20 (modular aluminum framing), Ardurra (engineering/design), GDS Associates (power infrastructure consulting), Lipari Foods (specialty food distribution), Pritchard Industries (facility services), AHSG (healthcare staffing with proprietary Trio VMS and Insight ATS+ SaaS platforms), Total Safety (industrial safety services), RailPros (rail engineering services), Valcourt Building Services (exterior building maintenance), and United Comfort Group (HVAC/plumbing services) — each held as a current or realized investment within Littlejohn's funds.
