## Questions

### Who runs investment decisions at Sonoran Investment Advisors?

Founder and Managing Partner Mark Sober leads all investment decisions. He often takes a direct board or CEO role at acquired companies, making Sonoran an operator-led rather than committee-led investment office.

### Does Sonoran invest in funds or only direct deals?

Sonoran invests exclusively in direct-control buyouts of private operating companies. The firm does not make fund commitments or participate as a limited partner in third-party vehicles. Its structure is closer to a holding company than a fund-of-funds.

### How long does Sonoran typically hold its investments?

Sonoran operates with a permanent-capital mandate. It does not raise outside funds or operate on a fixed investment period, so it can hold portfolio companies indefinitely. No public exit has been recorded since the firm's founding.

### What size companies does Sonoran target?

Sonoran pursues lower-middle-market companies with established profitability. While specific revenue or EBITDA thresholds are not publicly disclosed, the firm avoids venture-stage businesses and seeks companies with proven cash flows and recurring revenue models.

### Which sectors does Sonoran explicitly avoid?

Sonoran has not publicly issued a formal exclusion list. Its observed deal pattern avoids venture-stage technology, biotech, and speculative real estate development. The firm has concentrated on essential-service industries with government or recurring commercial revenue.
