EuclidSR Partners

Graham Anderson serves as Managing Director and Chief Investment Officer, leading the investment committee. Mathieu Guillemin is Managing Director and shares responsibility for origination and portfolio construction. The partnership structure keeps decision-making concentrated at the senior level.

EuclidSR underwrites to the collateral value of hard assets — power plants, pipelines, renewable installations — rather than relying on sponsor equity cushions or cash-flow projections. Loans are secured by revenue-generating physical assets, which provides a defined recovery path in downside scenarios and reduces correlation to sponsor-led leveraged buyout credit.

The firm originates and structures its own direct loans. It does not allocate to external private credit funds or operate a fund-of-funds program. All capital is deployed through bilateral or club-style senior secured, mezzanine, and structured equity transactions sourced by the internal team.

EuclidSR commits $15 million to $75 million per transaction to middle-market borrowers with established, income-producing assets. The firm targets companies at the project-finance or operational-expansion stage, not greenfield development. It provides senior secured loans, mezzanine tranches, and structured equity co-investments alongside its credit positions.

Deal flow is proprietary and relationship-based. The firm sources directly from asset operators, engineering firms, equipment manufacturers, and project developers rather than through auction processes run by investment banks. This direct-origination model allows EuclidSR to negotiate bespoke structural protections before competing capital enters a process.

The firm does not lend to sponsor-backed buyouts, general middle-market corporate cash-flow loans, or venture-stage companies. It also avoids pure-play fossil-fuel extraction without an energy-transition component, concentrating instead on power generation, midstream infrastructure, and renewable-energy assets.

The portfolio is concentrated in North America, primarily the United States, where energy infrastructure and renewable projects fall under a well-established regulatory and contractual framework. The firm has evaluated select Western European opportunities but has historically deployed the majority of capital domestically.
