## Questions

### Who makes investment decisions at Sarr Group?

Leslie A. Brun, as Chairman and CEO, is the central decision-maker for all investment activity. His authority is concentrated; Sarr Group does not run an institutional committee process but operates more like a personal investment office where Brun's judgment, shaped by decades of board service and private-markets deal-making, controls capital deployment.

### What is the relationship between Sarr Group and Hamilton Lane?

Leslie Brun founded Hamilton Lane in 1991 and built it into a leading private-markets advisory and fund-of-funds manager. In 2003, he sold a controlling stake to a consortium led by Cascade Investment, the firm that manages Bill Gates's personal wealth. Sarr Group formed after that exit and now serves as Brun's direct investment platform, independent of the Hamilton Lane franchise.

### Where does the underlying capital come from?

The capital base originates from Leslie Brun's business career, notably the sale of his controlling stake in Hamilton Lane in 2003. Additional wealth has been accumulated through four decades of board service at public companies including Merck, and through Sarr Group's own investment returns. The firm does not disclose total assets.

### Does Sarr Group participate in fund commitments or only direct deals?

Sarr Group's known activity centers on direct investments and co-investments rather than blind-pool fund commitments. Brun's background as a fund-of-funds operator at Hamilton Lane gives him the relationships to access manager-led co-investment opportunities, but the firm's private-capital posture tilts toward direct positions where Brun can evaluate specific assets using his boardroom governance lens.

### What is Leslie Brun's board network, and how does it shape deal flow?

Brun's network runs through multiple interlocking institutions: he is a member of the Council on Foreign Relations, serves as Vice Chairman and Senior Advisor at G100 Companies, and was recognized by the National Association of Corporate Directors as a Top 100 director. His long board tenure at Merck connected him with Ken Frazier. These relationships, rather than a formal sourcing engine, shape the inbound opportunities Sarr Group sees.
