Diamond Hill Small-Mid Cap Strategy Q1 2026 Portfolio Activity

We do not believe Humana's current share price reflects the company's earnings power, and as industry conditions normalize, we believe it can return to target margins over the long term. We initiated a position in Antero Resources, a natural gas exploration and production company, to gain exposure given our constructive long-term outlook for US natural gas. We exited our position in First Advantage, a leader in the background check space, to pursue other opportunities with less macro exposure and AI-disruption concerns.
