Financial Highlights

(In thousands, except percentages and per share data) Three Months Ended September 30, 2025 September 30, 2024U.S. GAAP Revenue $63,217 $57,546 Expenses 46,595 35,917 Operating income 16,622 21,629 Non-operating income 4,340 1,027 Net income 15,207 16,834 Diluted earnings per share $0.68 $0.69 Operating margin 26.3% 37.6%

Giving Back to Society - $80 million since IPO

Since our initial public offering in February 1999, our firm’s combined charitable donations total approximately $80 million, including $48 million through the shareholder designated charitable contribution program. Based on the program created by Warren Buffett at Berkshire Hathaway, our corporate charitable giving is unique in that the recipients of Gabelli’s charitable contributions are chosen directly by our shareholders, rather than by our corporate officers. Since its inception in 2013, Gabelli shareholders have designated charitable gifts to approximately 350 charitable organizations.

The charitable giving program continues today with the Gabelli Funds Foundation, a private foundation, established in September 2024. On November 7, 2025, Gabelli’s board of directors authorized an additional $2.5 million contribution.

Revenue

(In thousands) Three Months Ended September 30, 2025 September 30, 2024 Investment advisory and incentive fees Funds $42,803 $38,847 Institutional and Private Wealth Management 16,531 14,977 SICAV 13 5 Performance-based (13) - Total $59,334 $53,829 Distribution fees and other income 3,883 3,717 Total revenue $63,217 $57,546

The year over year increase in Funds revenues was primarily the result of higher average assets under management. The Institutional and Private Wealth Management increase in revenues was the result of higher equity assets (including the addition of the PWM assets of Gabelli-Keeley in May 2025) at the beginning of the quarter, which are generally used to calculate the revenues. The increase in distribution fees and other income was primarily the result of an increase in equity mutual funds AUM that pay distribution fees.

Expenses

(In thousands) Three Months Ended September 30, 2025 September 30, 2024 Compensation $32,762 $22,566 Management fee 2,338 2,517 Distribution costs 5,920 6,033 Other operating expenses 5,575 4,801 Total expenses $46,595 $35,917

The higher compensation expense in the third quarter of 2025 compared to the prior year quarter is comprised of $2.6 million of higher fixed compensation, $2.1 million of higher variable compensation and the $5.5 million of waived compensation in the 2024 quarter.

Operating Margin

The operating margin, which represents the ratio of operating income to revenue, was 26.3% for the third quarter of 2025 compared with 37.6% for the third quarter of 2024.

Non-Operating Income

(In thousands) Three Months Ended September 30, 2025 September 30, 2024 Gain from investments, net $2,835 $3,370 Interest and dividend income 1,868 2,947 Interest expense (a) (363) (290) Charitable giving contribution - (5,000) Total non-operating income $4,340 $1,027 (a) Related to GAAP accounting of finance lease.

Non-operating income was $3.3 million higher for the quarter, after accounting for the $5.0 million contribution made in the 2024 period to establish the private foundation in support of our ongoing charitable giving program. This was partially offset by lower mark-to-market values on our investments portfolio for the quarter and a decrease in interest and dividend income.

Other Financial Highlights

The Gabelli Gold Fund – Up 42% For 3rd quarter of 2025

Portfolio manager Caesar Bryan commented on The Gabelli Gold Fund’s 3rd quarter 2025 performance:

The third quarter of 2025 saw a sharp advance in both the gold price and gold equities. Building on strong gains earlier in the year, the price of gold rose by 16.7% during the quarter, climbing from $3,306 to $3,859 per ounce. Gold equities appreciated by well over 40% and again outpaced the metal, maintaining the leverage historically associated with the sector after years of underperformance. This continued strength occurred against a backdrop of currency volatility, mounting fiscal pressures, and geopolitical risk. These tailwinds have kept gold in demand from central banks, particularly in China and emerging markets where trust in dollar-based reserves is increasingly questioned. Despite their strong performance gold equities only recently surpassed their prior highs from 2011. At today’s gold price we calculate many of our portfolio companies are trading at mid and high teens free cash flow yields on 2026 earnings and a significant discount to net present value. We believe this is supportive of higher prices.
