Industry Context

The acquisition reflects a trend in the investment management industry towards consolidation, with larger firms seeking to expand their asset class offerings (e.g., First Eagle's increased fixed income footprint) and geographic reach, while boutique firms may seek the resources and distribution networks of larger partners. The emphasis on maintaining Diamond Hill's brand and investment philosophy suggests a strategy to integrate without disrupting successful existing operations, common in asset management M&A to retain talent and client assets.

Comparison to Industry Standards

• The 49% premium over the closing share price and 44% premium over the 30-day VWAP is a significant premium, generally considered attractive in M&A transactions for publicly traded companies.
• The client consent threshold of 78% of revenue run-rate is a common, but often challenging, condition in asset management acquisitions, reflecting the importance of retaining client assets post-merger.
• The "go-shop" period is a standard M&A practice that allows the target company to seek higher bids, ensuring fiduciary duties are met.
• The structure of maintaining the acquired brand and investment team is a common strategy in asset management to preserve investment culture and client relationships.

Management Changes

Corporate Governance

Legal Proceedings

• Potential litigation relating to the merger could be instituted against the parties to the definitive transaction agreement or their respective directors or officers.
• The Company will control the defense or settlement of any litigation relating to the merger, but must give Parent a meaningful opportunity to consult and will not settle without Parent's prior written consent (not unreasonably withheld, conditioned or delayed).

Related Party Transactions

• Executive Severance/Non-Solicitation Letter Agreements were entered into by First Eagle Investment Management, LLC with Heather Brilliant (CEO) and Jo Ann Quinif (President and Chief Client Officer) of Diamond Hill. These agreements modify existing employment terms, extending non-solicitation restrictions and expanding their scope in exchange for additional severance equal to one year of their respective base salaries, payable upon termination without cause or resignation for good reason in connection with the transaction.

Stakeholder Impact

• Shareholders: Will receive a significant all-cash premium of $175.00 per share, representing a 49% premium over the last closing price. However, they will lose future public market participation in Diamond Hill and will not receive further quarterly dividends through closing.
• Employees: Diamond Hill will maintain its existing investment teams, philosophy, and process, suggesting continuity. Key executives (CEO and President) receive additional severance benefits in exchange for extended non-solicitation clauses.
• Clients: Diamond Hill will continue serving clients with the same investment team and philosophy, enhanced by First Eagle's global resources and distribution network. Client consent for a minimum of 78% of the aggregate revenue run-rate is a critical closing condition, indicating efforts to retain client relationships.
• Management: Management's attention will be diverted to transaction-related matters, and the roles of directors and officers will transition to those of Merger Sub post-merger.

Next Steps

• Diamond Hill to establish a record date, call, and mail a proxy statement for a shareholder meeting.
• Diamond Hill shareholders to vote on the adoption of the Merger Agreement.
• Expiration or early termination of the Hart-Scott-Rodino Antitrust Improvements Act (HSR Act) waiting period.
• Obtain client consents for at least 78% of the aggregate revenue run-rate as of November 30, 2025.
• First Eagle and Diamond Hill to synchronize fund boards at closing.
• Transaction expected to close by the third quarter of 2026.
• Diamond Hill to delist from NASDAQ and deregister under the 1934 Act post-merger.
• Go-shop period for Diamond Hill until January 14, 2026, to solicit alternative acquisition proposals.

Key Dates

Recommendation

The all-cash offer of $175.00 per share represents a substantial 49% premium over the last closing price and a 44% premium over the 30-day VWAP, providing immediate and certain value to Diamond Hill shareholders. The unanimous board approval further underscores the attractiveness of the offer. While there are standard closing conditions and risks, the significant premium makes this a compelling opportunity for shareholders to realize substantial gains.
