Management Commentary

“For the third quarter, Fidus’ portfolio performed well, producing adjusted net investment income that continued to amply cover our base dividend for our shareholders. With net originations of $37.8 million, we further built our total portfolio, primarily providing some of our existing portfolio companies with growth capital,” said Edward Ross, Chairman and CEO of Fidus Investment Corporation. “Subsequent to quarter end, we invested $40.2 million in two new portfolio companies. Our pipeline of new investments and add-ons in existing portfolio companies remains strong, and reflects our proven strategy of carefully selecting investments in companies with reliable cash-generating business models and attractive prospects for growth. As we convert opportunities in our pipeline, by adhering to our underwriting discipline we intend to maintain a portfolio that is structured to generate attractive risk adjusted returns and grow NAV over time.”

Supplemental information regarding adjusted net investment income:

On a supplemental basis, we provide information relating to adjusted net investment income, which is a non-GAAP measure. This measure is provided in addition to, but not as a substitute for, net investment income. Adjusted net investment income represents net investment income excluding any capital gains incentive fee expense or (reversal) attributable to realized and unrealized gains and losses. The management agreement with our investment adviser provides that a capital gains incentive fee is determined and paid annually with respect to cumulative realized capital gains (but not unrealized capital gains) to the extent such realized capital gains exceed realized and unrealized losses. In addition, we accrue, but do not pay, a capital gains incentive fee in connection with any unrealized capital appreciation, as appropriate. As such, we believe that adjusted net investment income is a useful indicator of operations exclusive of any capital gains incentive fee expense or (reversal) attributable to realized and unrealized gains and losses. The presentation of this additional information is not meant to be considered in isolation or as a substitute for financial results prepared in accordance with GAAP. Reconciliations of net investment income to adjusted net investment income are set forth in Schedule 1.

Third Quarter 2025 Financial Results

The following table provides a summary of our operating results for the three months ended September 30, 2025, as compared to the same period in 2024 (dollars in thousands, except per share data):



	Three Months Ended September 30,
	2025		2024		$ Change			% Change
Interest income	$	30,815	$	31,857	$	(1,042	)		(3.3	%)
Payment-in-kind interest income		3,185		1,851		1,334			72.1	%
Dividend income		989		1,384		(395	)		(28.5	%)
Fee income		1,322		2,693		(1,371	)		(50.9	%)
Interest on idle funds		942		597		345			57.8	%
Total investment income	$	37,253	$	38,382	$	(1,129	)		(2.9	%)

Net investment income	$	17,369	$	21,411	$	(4,042	)		(18.9	%)
Net investment income per share	$	0.49	$	0.64	$	(0.15	)		(23.4	%)

Adjusted net investment income (1)	$	17,723	$	20,424	$	(2,701	)		(13.2	%)
Adjusted net investment income per share (1)	$	0.50	$	0.61	$	(0.11	)		(18.0	%)

Net increase (decrease) in net assets resulting from operations	$	19,138	$	16,477	$	2,661			16.1	%
Net increase (decrease) in net assets resulting from operations per share	$	0.54	$	0.49	$	0.05			10.2	%

The $1.1 million decrease in total investment income for the three months ended September 30, 2025, as compared to the same period in 2024, was primarily attributable to (i) a $0.3 million increase in total interest income (which includes a $1.4 million increase in payment-in-kind interest income) resulting from an increase in average debt investment balances outstanding, partially offset by a decrease in weighted average yield on debt investment balances outstanding, (ii) a $0.4 million decrease in dividend income due to a decrease in distributions received from equity investments, (iii) a $1.4 million decrease in fee income resulting from a decrease in prepayment, origination, and amendment fees, and (iv) a $0.4 million increase in interest on idle funds resulting from an increase in average cash balances.

For the three months ended September 30, 2025, total expenses, including the base management fee waiver and income tax provision, were $19.9 million, an increase of $2.9 million, or 17.2% from the $17.0 million of total expenses, including the base management fee waiver and income tax provision, for the three months ended September 30, 2024. The increase was primarily attributable to (i) a $1.6 million increase in interest and financing expenses due to an increase in the weighted average interest rate of our debt outstanding and an increase in weighted average borrowings outstanding, (ii) a $0.5 million net increase in base management fee, including the base management fee waiver, due to higher average total assets, (iii) a $0.2 million increase in professional fees due to increased legal fees, (iv) a $1.4 million increase in the accrued capital gains incentive fee due to a net $6.7 million increase in net gain on investments and realized losses on extinguishment of debt, and (v) a $0.8 million decrease in the income incentive fee due to a decrease in pre-incentive fee net investment income during 2025 as compared to the same period in 2024.

Net investment income decreased by $4.0 million, or (18.9)%, to $17.4 million during the three months ended September 30, 2025 as compared to the same period in 2024, as a result of the $(1.1) million decrease in total investment income and the $2.9 million increase in total expenses, including base management fee waiver and income tax provision. Adjusted net investment income,(1) which excludes the capital gains incentive fee accrual, was $0.50 per share compared to $0.61 per share in the prior year.

For the three months ended September 30, 2025, the total net realized gain/(loss) on investments, net of income tax (provision)/benefit on realized gains, was $(1.4) million, as compared to total net realized gain/(loss) on investments, net of income tax (provision)/benefit on realized gains, of $(0.4) million for the same period in 2024.

Portfolio and Investment Activities

As of September 30, 2025, the fair value of our investment portfolio totaled $1.2 billion and consisted of 92 active portfolio companies and six portfolio companies that have sold their underlying operations. Our total portfolio investments at fair value were approximately 102.0% of the related cost basis as of September 30, 2025. As of September 30, 2025, the debt investments of 50 portfolio companies bore interest at a variable rate, which represented $755.3 million, or 72.0%, of our debt investment portfolio on a fair value basis, and the remainder of our debt investment portfolio was comprised of fixed rate investments. As of September 30, 2025, our average active portfolio company investment at amortized cost was $12.6 million, which excludes investments in six portfolio companies that have sold their underlying operations. The weighted average yield on debt investments was 13.0% as of September 30, 2025. The weighted average yield was computed using the effective interest rates for debt investments at cost as of September 30, 2025, including the accretion of original issue discounts and loan origination fees, but excluding investments on non-accrual status and investments recorded as a secured borrowing.

Third quarter 2025 investment activity included the following new portfolio company investments:

•

Sogno Toscano LLC, a single brand distributor of authentic high-quality Italian foods, primarily serving the food service industry. Fidus invested $8.5 million in first lien debt and $4.3 million in preferred equity.

Liquidity and Capital Resources

As of September 30, 2025, we had $62.3 million in cash and cash equivalents and $125.0 million of unused capacity under our senior secured revolving credit facility (the “Revolving Credit Facility”). For the three months ended September 30, 2025, we received net proceeds of $19.6 million from the equity at-the-market program, received $5.0 million of SBA debentures, and redeemed $16.0 million of SBA debentures. As of September 30, 2025, we had SBA debentures outstanding of $191.0 million, $100.0 million outstanding of the 4.75% notes due January 2026 (the “January 2026 Notes”), $125.0 million outstanding of our 3.50% notes due November 2026 (the “November 2026 Notes”), and $100.0 million outstanding of our 6.75% March 2030 Notes (the “March 2030 Notes” and together with the January 2026 Notes and the November 2026 Notes, the “Notes”). As of September 30, 2025, the weighted average interest rate on total debt outstanding was 4.9%.

Fourth Quarter 2025 Dividends Totaling $0.50 Per Share Declared

On November 3, 2025, our board of directors declared a base dividend of $0.43 per share and a supplemental dividend of $0.07 per share for the third quarter. The dividends will be payable on December 29, 2025, to stockholders of record as of December 19, 2025.

When declaring dividends, our board of directors reviews estimates of taxable income available for distribution, which differs from consolidated income under GAAP due to (i) changes in unrealized appreciation and depreciation, (ii) temporary and permanent differences in income and expense recognition, and (iii) the amount of undistributed taxable income carried over from a given year for distribution in the following year. The final determination of 2025 taxable income, as well as the tax attributes for 2025 dividends, will be made after the close of the 2025 tax year. The final tax attributes for 2025 dividends will generally include ordinary taxable income but may also include capital gains, qualified dividends and return of capital.

Fidus has adopted a dividend reinvestment plan (“DRIP”) that provides for reinvestment of dividends on behalf of its stockholders, unless a stockholder elects to receive cash. As a result, when we declare a cash dividend, stockholders who have not “opted out” of the DRIP at least two days prior to the dividend payment date will have their cash dividends automatically reinvested in additional shares of our common stock. Those stockholders whose shares are held by a broker or other financial intermediary may receive dividends in cash by notifying their broker or other financial intermediary of their election.

Schedule 1

Supplemental Information Regarding Adjusted Net Investment Income

On a supplemental basis, we provide information relating to adjusted net investment income, which is a non-GAAP measure. This measure is provided in addition to, but not as a substitute for, net investment income. Adjusted net investment income represents net investment income excluding any capital gains incentive fee expense or (reversal) attributable to realized and unrealized gains and losses. The management agreement with our investment advisor provides that a capital gains incentive fee is determined and paid annually with respect to cumulative realized capital gains (but not unrealized capital gains) to the extent such realized capital gains exceed realized and unrealized losses for such year, less the aggregate amount of any capital gains incentive fees paid in all prior years. In addition, we accrue, but do not pay, a capital gains incentive fee in connection with any unrealized capital appreciation, as appropriate. As such, we believe that adjusted net investment income is a useful indicator of operations exclusive of any capital gains incentive fee expense or (reversal) attributable to realized and unrealized gains and losses. The presentation of this additional information is not meant to be considered in isolation or as a substitute for financial results prepared in accordance with GAAP. The following table provides a reconciliation of net investment income to adjusted net investment income for the three and nine months ended September 30, 2025 and 2024.

Due to rounding, the sum of net investment income per share and capital gains incentive fee expense (reversal) amounts may not equal the adjusted net investment income per share amount presented here.
