## Questions

### Who runs investment decisions at Diamond Hill?

Chris Welch serves as Chief Investment Officer, overseeing a unified investment platform where each portfolio manager has autonomy within a shared intrinsic-value framework. Heather Brilliant, as CEO since 2019, shapes firm-wide investment culture but does not directly manage portfolios. The firm's public filings list its portfolio managers by name with biographical detail on tenure and coverage.

### How is Diamond Hill different from other value managers in the same AUM band?

The firm is publicly traded and employee-owned, with portfolio managers required to hold the majority of their liquid net worth in Diamond Hill strategies. Compensation ties to rolling five-year, risk-adjusted performance rather than calendar-year rankings. The firm also caps strategy capacity internally before assets dilute the ability to compound, which is unusual among publicly traded asset managers where AUM growth often drives equity valuation.

### What asset classes does Diamond Hill actually manage?

The firm runs U.S. large-cap equity, small-to-mid-cap equity, and fixed-income strategies through mutual funds and separately managed accounts. All draw from the same intrinsic-value research platform. In 2024, it added a long-short equity fund that applies the same concentrated bottom-up methodology to both long and short positions.

### What is the ownership structure, and why does it matter for institutional allocators?

Diamond Hill is employee-owned and publicly traded on Nasdaq (DHIL). Because portfolio managers' compensation and share ownership track long-term investment outcomes, the structure narrows the principal-agent gap that can arise when a firm's equity trades on a separate metric from its funds' performance. Allocators frequently view this alignment as a structural mitigant against style drift and short-termism.
