Diamond Hill Investment Group, Inc. (DHIL)

Diamond Hill Investment Group, Inc. is the holding company for Diamond Hill Capital Management, an investment adviser headquartered in Columbus, Ohio. The firm traces its origins to 2000, when Diamond Hill Capital Management was founded with a philosophy centered on long-term, intrinsic-value investing. The parent company itself dates to an earlier corporate predecessor from 1990 that later became the vehicle for the investment business.

The firm offered a range of strategies, primarily in U.S. equities, along with fixed income and alternative approaches. Clients were served through the Diamond Hill Funds mutual fund family, separately managed accounts, model delivery programs, and private investment funds. Diamond Hill also provided fund administration services, covering compliance, treasury and oversight of service providers for its fund complex.

A defining feature of the company was its emphasis on alignment with clients. It limited the capacity of its strategies, compensated investment professionals largely on long-term investment results, and encouraged employees to invest alongside clients. The company's shares traded on the Nasdaq Global Select Market under the symbol DHIL, and its stock was notable for its high per-share price compared with most asset managers.

Diamond Hill returned capital to shareholders through regular and special dividends, which became a hallmark of the company's approach. Like many active equity managers, it operated amid industry pressure from the shift toward passive funds and fee compression, which affected assets under management and revenue growth across the sector.

In 2026, Diamond Hill agreed to be acquired by First Eagle Investments, a global asset management firm. The agreement provided for $175 per share in cash, valuing the transaction at approximately $473 million. The deal combined Diamond Hill's value-oriented U.S. equity capabilities with First Eagle's broader distribution platform.

The acquisition was completed on April 22, 2026, after the closing conditions were satisfied. Diamond Hill became a wholly owned subsidiary of First Eagle Investments, shareholders received the cash consideration, and Nasdaq trading in DHIL ended. A Form 25 was filed with the SEC to remove the shares from listing and registration.
