## Questions

### Who runs investment decisions at Sidus Investment Management?

Gregory D. Thayer serves as President and Chief Investment Officer and personally leads all underwriting and portfolio decisions. Sidus does not use an external investment committee — Thayer's credit judgment and direct negotiation with borrowers drive the process. This concentrated decision-making is a deliberate structural feature rather than a transitory stage.

### How does Sidus source its deal flow?

Sidus deliberately avoids competitive auction processes, sourcing most investments through Thayer's direct relationships with owner-operators, commercial bankers, and regional intermediaries. The firm cultivates referral networks among accountants and attorneys serving lower-middle-market businesses in the Midwest and Appalachia. This origination model seeks complex or time-sensitive situations where Sidus can act as the only institutional capital provider at closing.

### Does Sidus raise funds or operate on a deal-by-deal basis?

Sidus raises capital predominantly on a deal-by-deal basis and through targeted vehicles rather than traditional blind-pool funds with a fixed term and size. In July 2023, the firm launched a dedicated vehicle for energy-transition service-company credit, one of its few structured pools. Individual investors and family offices commit capital per transaction, giving Sidus flexibility on sizing and hold periods.

### What investment stages does Sidus typically target?

Sidus targets mature, cash-flowing middle-market companies that need growth capital, acquisition financing, or liquidity for owner-operators. The firm rarely invests in startups, early-stage ventures, or pre-revenue situations. Its real estate practice similarly focuses on existing income-producing properties undergoing renovation, repositioning, or lease-up.

### Does Sidus participate in energy investments outside of credit?

Sidus's energy practice includes direct royalty interests in producing oil and gas wells in addition to structured credit. The firm targets cash-flowing mineral and royalty positions in Appalachia and the Permian Basin, purchasing interests from operators and individual mineral owners. Its 2023 energy-transition vehicle extends the credit practice into service companies supporting emissions reduction and efficiency.
