FOR IMMEDIATE RELEASE

Hennessy Advisors, Inc. Reports Quarterly Earnings

and Announces Quarterly Dividend

August 6, 2025, Novato, CA - Hennessy Advisors, Inc. (Nasdaq:HNNA) today announced financial results for its third fiscal quarter of 2025, which ended June 30, 2025. The Company also declared a quarterly dividend of $0.1375 per share to be paid on September 4, 2025, to shareholders of record as of August 20, 2025. This represents an annualized dividend yield of 4.4%, based on a closing price of $12.63 on August 5, 2025.

“While equity markets continued to rise and reach new highs in the first half of 2025, volatility persisted due to uncertainty around inflation, tariffs, and delays in anticipated Fed rate cuts,” said Neil Hennessy, Chairman and CEO. “Rather than react to the constant flurry of financial headlines, we stay grounded in the fundamentals. In my opinion, the U.S. labor market has proven remarkably resilient, with historically low unemployment and consistent payroll growth. GDP is rising modestly, while inflation continues to moderate – I believe both of which are boosting consumer sentiment. We’re also seeing encouraging signs in corporate earnings and businesses putting money to work – upgrading operations, expanding capacity, and leaning into growth for the future.”

“With the passage of major fiscal legislation in early July, I believe investors now have the clarity needed to refocus on the strength of the economic data. I remain confident in the resilience of the market and optimistic about future performance. As always, we remain calm, focused, and committed to delivering long-term value to our shareholders,” he added.

“We’re pleased to report growth in assets under management, continued positive earnings, ongoing quarterly dividend payments, and a growing cash position – each of which strengthens our ability to capitalize on future opportunities. We also remain focused on completing the process for Hennessy Advisors to assume management of the STF Tactical Growth & Income ETF and the STF Tactical Growth ETF, which would expand our ETF offerings,” said Teresa Nilsen, President and COO.
