Overview

Quabbin Capital traces its origins to 1974, when it began Boston-based commercial real estate activities, and describes itself as a privately-held investment management firm with over one hundred direct and fund investments across private lower-middle-market companies, venture capital, energy and real estate; in recent years it has moved to sourcing and sponsoring lower-middle-market private equity deals directly. In a July 2020 McGuireWoods interview, then-principal Charles 'Chip' Wahle said the firm was founded as a family office more than 30 years earlier and manages the US assets of a single offshore family whose wealth came from infrastructure and construction; the family typically funds about 10% of a deal's equity and Quabbin raises the balance from outside equity, mezzanine and senior-debt partners, a model he called a 'semi-funded sponsor'. It targets family- or founder-owned businesses with EBITDA of USD 2-5 million, making control and non-control equity investments. Current portfolio companies listed are Upper Crust Pizzerias and RIMCO Royalty Partners; its site lists 15 realized investments, including Chandler Signs, Applied Business Software, SAMBA Safety, Perma-Fix Environmental Services, Lift Tech International and The Lofland Company.

Investment thesis

Patient, detail-oriented investing in family- or founder-owned lower-middle-market companies with USD 2-5 million EBITDA, proprietary products or services, technology-enabled processes and growth plans including acquisitions, often as the first outside capital provider. The philosophy page cites a 3-5 year ownership exit strategy; the contact page says the hold period has no structural limits and is typically long term.
