Shareholders also approved, on an advisory basis, merger-related executive compensation.

Diamond Hill Investment Group outlines its asset-management business and a pending sale to First Eagle Investment Management. Under a signed merger agreement, each DHIL common share will be converted into $175.00 in cash, subject to shareholder approval, regulatory clearances, and client-consent thresholds covering at least 78% of revenue run‑rate.
As of December 31, 2025, the company managed $29.4 billion in assets under management and $1.6 billion in assets under advisement, with revenues heavily tied to Proprietary Funds and concentrated strategies such as Large Cap, Long‑Short, and Short Duration Securitized Bond. In 2025, net client cash outflows of $2.7 billion were partially offset by $2.1 billion of market appreciation.
The filing details competitive and regulatory pressures on active managers, operational and cybersecurity controls (including ISO 27001‑certified programs), and extensive merger-related risks, including client consent, integration, litigation, and a potential $18.0 million termination fee if the deal ends under specified circumstances. If completed, DHIL will become a wholly owned, private subsidiary of First Eagle and its shares will be delisted.
Diamond Hill Investment Group describes its pending merger with First Eagle Investment Management, under which a First Eagle subsidiary will merge into Diamond Hill, leaving Diamond Hill as a wholly owned subsidiary. The merger is expected to close in the second quarter of 2026, subject to shareholder approval and required client consents based on revenue run rate.
In connection with this transition, the Compensation Committee granted Chief Financial Officer and Treasurer Thomas E. Line a deferred cash-based award of $100,000. He earns this one-time payment if he remains employed with the buyer or Diamond Hill through February 20, 2027, or if he is terminated without cause or resigns for good reason before that date, contingent on signing and not revoking a separation agreement and release of claims.
Diamond Hill Investment Group provides an update on its planned merger with First Eagle Investment Management and related shareholder litigation. A special shareholder meeting is scheduled for March 3, 2026, for investors of record as of January 27, 2026 to vote on the merger.
Subject to shareholder approval and other conditions, including client consents based on revenue run-rate, the company expects the merger to close in the second quarter of 2026. Two individual shareholder lawsuits in New York state court allege that the definitive proxy statement contains misleading omissions and seek to block completion of the deal.
Attorneys for additional purported shareholders have also sent demand letters raising similar disclosure concerns and threatening further suits. While Diamond Hill believes these claims are without merit, it is voluntarily providing supplemental proxy disclosures to reduce litigation risk and give shareholders additional information before they vote.
Diamond Hill Investment Group reported that the Federal Trade Commission granted early termination of the Hart-Scott-Rodino antitrust waiting period on February 10, 2026 for its planned merger with First Eagle Investment Management. This antitrust clearance satisfies one of the key conditions to closing the transaction.
The merger remains subject to other conditions, including shareholder approval and required client consents based on revenue run-rate. A special shareholder meeting to vote on the merger is scheduled for March 3, 2026, and the companies currently expect the deal to close in the second quarter of 2026.
