Opinion on the Financial Statements

We have audited the accompanying balance sheet of Hennessy Advisors, Inc. (the “Company”) as of September 30, 2025, the related statements of income, changes in stockholders’ equity and cash flows for the year ended September 30, 2025, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of September 30, 2025, and the results of its operations and its cash flows for the year ended September 30, 2025, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audit** **provides a reasonable basis for our opinion.

Prior Period Financial Statements

The financial statements of the Company as of and for the year ended September 30, 2024, were audited by Marcum LLP, whose report dated December 11, 2024, expressed an unmodified opinion on those statements.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Valuation of the Management Contract Asset–* Impairment Consideration*

As described in Note 1(f) to the financial statements, the Company has historically capitalized the cost of purchasing management contracts as intangible assets. These intangible assets are considered to have indefinite useful lives and are therefore not amortized, but rather tested at least annually for impairment. As part of this annual test, management (i) evaluates whether events and circumstances indicate that it is more likely than not that impairment exists, and/or (ii) estimates the fair value of such intangible assets and compares it to the cost of the assets to determine whether impairment has occurred. Management’s estimate of the fair value of the management contract asset involves subjective assumptions that include stock market returns, fund flows and weighted average cost of capital.

We have determined that the valuation of the management contract asset constitutes a critical audit matter for the following reasons: (i) it is a matter that should be communicated to the audit committee, since it involves a significant management estimate; (ii) it involves a material account balance; and (iii) it involves especially subjective auditor judgment.

We have addressed this critical audit matter by performing appropriate audit procedures. These procedures included (i) assessing management’s evaluation of whether events or circumstances indicate that it is more likely than not that impairment exists; (ii) evaluating the reasonableness of management’s fair value estimate assumptions; and (iii) testing the mathematical accuracy of management’s valuation model. Professionals with specialized skills and knowledge were used to assist in evaluating the measurement of the Company’s estimated fair value of the management contract asset.
