## Questions

### Who runs investment decisions at SDCL?

Jonathan Maxwell, CEO and Founding Partner, leads the firm alongside a management team that includes Head of Investments and Head of Listed Funds. Investment decisions for SEEIT are made by SDCL's investment committee, which Maxwell chairs. Per the firm's website, the committee includes senior partners with backgrounds in infrastructure and credit.

### What types of assets does SDCL typically finance?

SDCL focuses on energy-efficiency upgrades, distributed generation (solar, combined heat and power), and energy-storage projects. Typical ticket sizes range from £5M to £50M per project, with targeted internal rates of return in the mid-teens for private debt and lower double-digits for direct equity, per 2023 investor materials.

### How does SDCL source deal flow?

The firm originates proprietary deals through direct relationships with building owners, local governments, and industrial operators who need capital to execute energy retrofits. Founded by a former infrastructure banker, the firm also partners with energy service companies (ESCOs) that deliver projects and share upside. SDCL does not rely on auction processes for the majority of its deals.

### Is SEEIT a listed vehicle and how does it work?

SEEIT is a UK Investment Company listed on the London Stock Exchange (ticker: SEIT). It invests exclusively in energy-efficiency and distributed-energy assets, largely through long-term debt and equity positions in project special purpose vehicles. The structure allows investors to trade shares on exchange while the underlying portfolio holds illiquid infrastructure assets with multi-year cash yields.

### What is the firm's known posture on climate impact vs. financial returns?

SDCL publicly states that energy-efficiency investments generate both measurable carbon reduction (verified by project-level monitoring) and contractual cash yields. The firm does not claim impact-first status; its stated investment objective for SEEIT is to generate a total return with long-term, inflation-linked income. The positive environmental outcome is treated as an attractive co-benefit rather than a concession.
