**Forward-Looking Statements**

This communication, the documents incorporated herein by reference and statements, whether oral or written, made from time to time by representatives of the Company, may contain or incorporate "forward-looking statements" within the meaning of federal securities laws. Forward-looking statements include, but are not limited to, statements regarding anticipated operating results, prospects and levels of assets under management, technological developments, economic trends (including interest rates and market volatility), expected transactions and similar matters. These forward-looking statements may include, without limitation, any statements preceded by, followed by or including words such as "may," "could," "can have," "believe," "expect," "aim," "anticipate," "target," "goal," "project," "assume," "budget," "potential," "estimate," "guidance," "forecast," "outlook," "would," "will," "continue," "likely," "should," "hope," "seek," "plan," "intend," and variations of such words and similar expressions. Similarly, descriptions of the Company's objectives, strategies, plans, goals, or targets are also forward-looking statements. Such forward-looking statements include but are not limited to statements about the proposed Merger, including the expected timetable for completing the Merger and statements that are not historical facts.

Forward-looking statements are based on the Company's expectations at the time such statements are made, speak only as of the dates they are made and are susceptible to a number of risks, uncertainties and other factors. While the Company believes that the assumptions underlying its forward-looking statements are reasonable, investors are cautioned that any of the assumptions could prove to be inaccurate and, accordingly, the Company's actual results and experiences may differ materially from the anticipated results or other expectations expressed in its forward-looking statements. Factors that may cause the Company's actual results or experiences to differ materially from results discussed in forward-looking statements include, but are not limited to the factors discussed in the section entitled "Risk Factors" in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2025, as filed with the Securities and Exchange Commission ("SEC"), and any factors discussed in the section entitled "Risk Factors" in any of our subsequently filed SEC filings, and the following: (i) the occurrence of any event, change, or other circumstance that could give rise to the right of one or both of the parties to terminate the definitive transaction agreement between the Company and Purchaser, including in circumstances requiring the Company to pay a termination fee; (ii) potential litigation relating to the Merger that could be instituted against the parties to the definitive transaction agreement or their respective directors or officers, including the effects of any outcomes related thereto; (iii) the possibility that the Merger does not close when expected or at all because required regulatory, shareholder, or other approvals and other conditions to closing are not received or satisfied on a timely basis or at all; (iv) reputational risk and potential adverse reactions of clients, employees or other business partners and the businesses generally, including those resulting from the announcement of the Merger, including any resulting reduction in the Company's AUM or AUA and the withdrawal, renegotiation or termination of any investment advisory agreements; (v) the risk that any announcements relating to the Merger could have adverse effects on the market price of the Company Common Shares; (vi) significant transaction costs associated with the Merger; and (vii) the diversion of management's attention and time from ongoing business operations and opportunities on Merger-related matters.

Forward-looking statements attributable to the Company or any person acting on its behalf are expressly qualified in their entirety by the cautionary statements above and in the Company's other public documents on file with the SEC. New risks and uncertainties arise from time to time, and factors that the Company currently deems immaterial may become material, and it is impossible for the Company to predict these events or how they may affect it. The Company undertakes no obligation to update

------

any forward-looking statements after the date they are made, whether as a result of new information, future events, changes in its expectations or developments or otherwise, except as required by law, although it may do so from time to time. The Company does not endorse any projections regarding future performance that may be made by third parties.

**Additional Information and Where to Find It**

This Form 8-K does not constitute an offer to buy or sell or the solicitation of an offer to buy or sell any securities. This communication relates to the Merger. In connection with the Merger, on January 28, 2026, the Company filed with the SEC a definitive proxy statement on Schedule 14A relating to a special meeting of its shareholders (the "Merger Proxy Statement"). This communication is not a substitute for the Merger Proxy Statement or any other document that the Company may file with the SEC and send to its shareholders in connection with the Merger. The Merger will be submitted to the Company's shareholders for their consideration. Before making any voting decision, the Company's shareholders are urged to read all relevant documents filed or to be filed with the SEC, including the Merger Proxy Statement, as well as any amendments or supplements to those documents, when they become available, because they will contain important information about the Company and the Merger.

The Company's shareholders may obtain a free copy of the Merger Proxy Statement, as well as other filings containing information about the Company, free of charge, at the SEC's website (www.sec.gov). Copies of the Merger Proxy Statement and other documents filed by the Company with the SEC may be obtained, without charge, by contacting the Company through its website at <u>www.diamond-hill.com</u>.

**Participants in the Solicitation**

The Company, its directors, executive officers and other persons related to the Company may be deemed to be participants in the solicitation of proxies from the Company's shareholders in connection with the Merger. Information about the directors and executive officers of the Company and their ownership of Company Common Shares is set forth in the section entitled "Executive Officer Stock Ownership and Retention Guidelines" in the Company's proxy statement for its 2025 annual meeting of shareholders, which was filed with the SEC on March 14, 2025 (and which is available at <u>https://www.sec.gov/ix?doc=/Archives/edgar/data/0000909108/000090910825000014/dhil-20250311.htm</u>). To the extent that holdings of the Company's securities by its directors or executive officers have changed since the amounts printed in the Company's proxy statement, such changes have been or will be reflected on Initial Statements of Beneficial Ownership of Securities on Form 3 and Statements of Changes in Beneficial Ownership on Form 4 filed with the SEC. Additional information regarding the participants in the proxy solicitation and a description of their direct and indirect interests, by security holdings or otherwise, will be included in the Merger Proxy Statement and other relevant materials to be filed with the SEC in connection with the Merger when they become available. Free copies of these documents may be obtained as described in the preceding paragraph.

**Non-GAAP Financial Measures and Reconciliation**

As supplemental information, the Company is providing certain financial measures that are based on methodologies other than GAAP ("non-GAAP"). Management believes the non-GAAP financial measures below are useful measures of the Company's core business activities, are important metrics in estimating the value of an asset management business, and help facilitate comparisons to Company operating performance across periods. These non-GAAP financial measures are presented for supplemental informational purposes only, should not be used as a substitute for financial measures calculated in accordance with GAAP and may be calculated differently from similarly titled non-GAAP measures used by other companies. The following schedules reconcile the differences between financial measures calculated in accordance with GAAP and non-GAAP financial measures for 2025 and 2024. Investors are encouraged to review the related GAAP financial measures and the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measures, as well as the Company's condensed consolidated financial statements and related notes in its annual report on Form 10-K for the year ended December 31, 2025.

<sup>(1)</sup> This non-GAAP adjustment removes the compensation expense resulting from market valuation changes in the Company's deferred compensation plans' liability and the related net gains/losses on investments designated as an economic hedge against the related liability. Amounts deferred under the deferred compensation plans are adjusted for appreciation/depreciation of investments chosen by participants. The Company believes it is useful to offset the non-operating investment income or loss realized on the hedges against the related compensation expense and remove the net impact to help readers understand the Company's core operating results and to improve comparability from period to period.

<sup>(2)</sup> This non-GAAP adjustment removes the impact that the consolidation of majority owned mutual funds has on the Company's GAAP consolidated statements of income. Specifically, the Company adds back the operating expenses and subtracts the investment income of the mutual funds the Company consolidates. The adjustment to net operating income represents the operating expenses of the consolidated mutual funds, net of the elimination of related management and administrative fees. The adjustment to net income attributable to common shareholders represents the net income of the consolidated mutual funds, net of redeemable non-controlling interests. The Company believes removing the impact of the consolidated mutual funds helps readers understand its core operating results and improves comparability from period to period.

<sup>(3)</sup> This non-GAAP adjustment represents the net gains or losses earned on the Company's non-consolidated investment portfolio that are not designated as economic hedges of the Company's deferred compensation plans' liability, non-consolidated seed investments, and other investments. The Company believes adjusting for these non-operating income or loss items helps readers understand the Company's core operating results and improves comparability from period to period.

<sup>(4)</sup> The income tax expense impacts were calculated and resulted in the overall non-GAAP effective tax rates of 26.9% for 2025 and 26.8% for 2024.

The Company does not recommend that investors consider non-GAAP financial measures alone, or as a substitute for, financial information prepared in accordance with GAAP.

**Cautionary Note Regarding Forward-Looking Statements**

Throughout this press release, the Company may make "forward-looking statements" within the meaning of the U.S. Private Securities Litigation Reform Act of 1995, as amended (the "PSLR Act"), Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Such statements are provided under the "safe harbor" protection of the PSLR Act of 1995. Forward-looking statements include, but are not limited to, statements regarding anticipated operating results, prospects and levels of AUM or AUA, technological developments, economic trends (including interest rates and market volatility), expected transactions and similar matters. The words "may," "believe," "expect," "anticipate," "target," "goal," "project," "estimate," "guidance," "forecast," "outlook," "would," "will," "continue," "likely," "should," "hope," "seek," "plan," "intend," and variations of such words and similar expressions identify forward-looking statements. Similarly, descriptions of the Company's objectives, strategies, plans, goals, or targets are also forward-looking statements. Forward-looking statements are based on the Company's expectations at the time such statements are made, speak only as of the dates they are made and are susceptible to a number of risks, uncertainties and other factors. While the Company believes that the assumptions underlying its forward-looking statements are reasonable, investors are cautioned that any of the assumptions could prove to be inaccurate and, accordingly, the Company's actual results and experiences may differ materially from the anticipated results or other expectations expressed in its forward-looking statements.

Factors that could cause the Company's actual results or experiences to differ materially from those expressed or implied by the forward-looking statements are discussed under Part I, Item 1A (Risk Factors) and elsewhere in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2025. These factors include, but are not limited to: (i) declines or volatility in the Company's AUM or AUA, whether due to market conditions, investment performance, client withdrawals, asset allocation decisions, or otherwise; (ii) the loss, renegotiation, non-renewal, or termination of investment advisory or administration agreements, including as a result of the pending merger or client consent requirements; (iii) risks related to, or the failure to consummate, the proposed acquisition of the Company by First Eagle Investment Management, LLC, including the failure to obtain required approvals or client consents, delays in completion, transaction-related costs, restrictions on operations prior to closing, disruption to business relationships, shareholder litigation, or failure to realize anticipated benefits; (iv) damage to the Company's reputation or adverse public perception; (v) failure to comply with investment guidelines, fiduciary obligations, regulatory requirements, or other contractual obligations; (vi) intense competition within the investment management industry, including from firms with greater resources or lower-fee or passive investment offerings; (vii) industry trends toward lower fee products, passive strategies, and model portfolio arrangements that may adversely impact revenues; (viii) adverse legal, regulatory, tax, or accounting developments or increased compliance costs; (ix) cybersecurity incidents, technology failures, or disruptions involving the Company or third-party service providers; (x) operational risks, including errors, systems interruptions, employee misconduct, or inadequate risk management controls; (xi) the Company's ability to adapt to technological change, including the effective and responsible development and use of artificial intelligence ("AI") and compliance with evolving AI-related regulations; (xii) losses on the Company's investments or fluctuations in investment income; (xiii) limitations on access to capital or increased costs of financing; (xiv) losses or liabilities not covered by insurance; (xv) adverse changes in interest rates, inflation, credit conditions, or capital markets; (xvi) changes in domestic or global economic, political, or geopolitical conditions, including political uncertainty and economic nationalism; (xvii) the effects of natural disasters, pandemics, or other catastrophic or unpredictable events; and (xviii) other risks and uncertainties described from time to time in the Company's filings with the U.S. Securities and Exchange Commission.

In light of the significant uncertainties in forward-looking statements, the inclusion of such information should not be regarded as a representation by the Company or any other person that its expectations, objectives and plans will be achieved. All forward-looking statements made in this press release are based on information presently available to the management of the Company and speak only as of the date hereof. Readers are cautioned not to place undue reliance on forward-looking statements. New risks and uncertainties arise from time to time, and factors that the Company currently deems immaterial may become material, and it is impossible for the Company to predict these events or how they may affect it. The Company assumes no obligation to update any forward-looking statements after the date they are made, whether as a result of new information, future events or developments or otherwise, except as required by law, although it may do so from time to time. The Company does not endorse any projections regarding future performance that may be made by third parties.
