OFS Capital Management, LLC, our investment adviser, may, from time to time and in its sole discretion, pay some or all of the commissions payable under the Equity Distribution Agreement or make additional supplemental payments to ensure that the sales price per share of our common stock in connection with the At-the-Market Offering made hereunder will not be less than our current net asset value per share.

RECENT DEVELOPMENTS

May 2026 Financial Update

On June 15, 2026, we announced that management's unaudited estimate of the range of our net asset value ("NAV") per share of our common stock as of May 31, 2026 is between $3.56 and $3.66. This estimate is not a comprehensive statement of our financial condition or results for the month ended May 31, 2026. This estimate did not undergo the Company's typical quarter-end financial closing procedures. We advise you that current estimates of our NAV per share may differ materially from future NAV estimates or determinations, including the determination for the period ending July 31, 2026, which will be reported in our monthly report on Form N-PORT.

Our financial condition, including the fair value of our portfolio investments, and results of operations may be materially impacted after May 31, 2026 by circumstances and events that are not yet known. To the extent our portfolio investments are adversely impacted by interest rate and inflation rate changes, the ongoing war between Russia and Ukraine, the escalated armed conflict and heightened regional tensions in the Middle East, activity in South America, the agenda of the U.S. Presidential administration, including the impact of tariff enactment and tax reductions, trade disputes with other countries, instability in the U.S. and international banking systems, the risk of recession or the impact of the prolonged shutdown of U.S. government services and related market volatility, or by other factors, we may experience a material adverse impact on our future NAV, net investment income ("NII"), the underlying value of our investments, our financial condition and the financial condition of our portfolio investments.

The preliminary financial data included in this May 2026 Financial Update has been prepared by, and is the responsibility of, OFS Credit's management. KPMG LLP has not audited, reviewed, compiled, or applied agreed-upon procedures with respect to the preliminary financial data. Accordingly, KPMG LLP does not express an opinion or any other form of assurance with respect thereto.

SECOND QUARTER 2026 HIGHLIGHTS AND FINANCIAL RESULTS

SECOND QUARTER HIGHLIGHTS

OTHER RECENT EVENTS

PORTFOLIO AND INVESTMENT ACTIVITIES

As of April 30, 2026, the total fair value of our investment portfolio was $197.4 million, comprised of broadly syndicated loan CLOs and middle-market loan CLOs with a total fair value of $193.6 million and $3.8 million, respectively. For the fiscal quarter ended April 30, 2026, our CLO equity cash flow yield6 was 13.79% based on amortized cost.

During the fiscal quarter ended April 30, 2026, we received net proceeds of $21.0 million from the repayment and sale of portfolio investments, which were primarily used to redeem shares of our 6.125% Series C Term Preferred Stock due April 2026 and 6.00% Series D Term Preferred Stock due June 2026.

RESULTS OF OPERATIONS

Interest Income

During the fiscal quarter ended April 30, 2026, interest income decreased to $9.2 million from $11.0 million during the prior quarter. The decrease in interest income was primarily due to a decrease in the interest income yield1 on our investment portfolio and a smaller average investment portfolio, at cost.

Expenses

During the fiscal quarter ended April 30, 2026, total expenses decreased by $0.7 million to $4.8 million, primarily due to an aggregate decrease of $0.5 million in base management and incentive fees.

Net Realized and Unrealized Gain (Loss) on Investments

During the fiscal quarter ended April 30, 2026, net loss on investments of $16.5 million was due to net realized losses of $7.5 million and net unrealized depreciation of $9.0 million. The net unrealized depreciation was primarily driven by significant declines in loan prices, a challenging CLO equity cash flow arbitrage environment and a modest increase in loan defaults.

Supplemental Information Regarding Core Net Investment Income

We provide information relating to Core NII (a non-GAAP measure) on a supplemental basis. This measure is not provided as a substitute for GAAP NII, but in addition to it. Our non-GAAP measures may differ from similar measures by other companies, even if similar terms are used to identify such measures. Core NII represents GAAP NII adjusted for differences in applicable cash distributions received on our CLO equity and equity-related investments that have not been optionally redeemed relative to income recognized in accordance with GAAP. OFS Capital Management, LLC, our investment adviser, uses this information in its internal analysis of results and believes that this information may be informative in gauging the quality of the Company's financial performance, identifying trends in its results, and providing meaningful period-to-period comparisons.

Income from investments in the "equity" class securities of CLO vehicles, for GAAP purposes, is recorded using the effective interest method; this is based on an estimated effective yield, at current amortized cost, to the expected redemption of the security utilizing assumed cash flows, including those CLO equity investments that have not made their inaugural distribution for the relevant period end. The result is an estimated effective yield for the investment in which the respective investment's cost basis is adjusted quarterly based on the difference between the actual cash received, or distributions entitled to be received, and the income recognized via the estimated effective yield calculation. Accordingly, investment income recognized on CLO equity and equity-related securities in the GAAP statement of operations differs from the cash distributions actually received by the Company during the period (referred to below as "CLO equity adjustments"). Therefore, management believes that Core NII may provide a useful indicator of distributable operating income, as this reflects a measure of potential cash availability, net of operating expenses, that could be utilized to cover distributions to common stockholders. We note that this non-GAAP measure has no bearing on the tax character of the common stock distributions made during the period, and future distributions are not guaranteed. A portion of current and future common stock distributions may consist of a return of capital for tax purposes. The actual tax character of our earnings cannot be finally determined until our tax return is prepared after the close of our taxable year.

The following table provides a reconciliation of GAAP NII to Core NII for the fiscal periods presented:

The following table provides a reconciliation of GAAP NII to Core NII for the six months ended April 30, 2026 and 2025:

1 Interest income yield is calculated as total investment income earned on the investment portfolio (excluding idle cash interest income) divided by the average total investments at cost (annualized).

2 On a supplemental basis, we disclose Core NII, which is a financial measure calculated and presented on a basis of methodology other than in accordance with accounting principles generally accepted in the United States of America ("GAAP"). Core NII represents NII adjusted for differences in applicable cash distributions received on our CLO equity and equity-related investments that have not been optionally redeemed relative to income recognized in accordance with GAAP. See additional information under "Supplemental Information Regarding Core Net Investment Income" above.

3 Under the Investment Company Act of 1940, as amended, we are permitted to issue senior securities, including preferred stock, provided that we maintain an asset coverage of at least 200% for senior securities representing indebtedness plus preferred stock, and 300% in the case of senior securities representing indebtedness. Asset coverage of senior securities representing preferred stock is calculated as the ratio of our total consolidated assets, less all liabilities and indebtedness not represented by senior

securities, divided by the aggregate amount of our outstanding preferred stock and debt. Asset coverage of senior securities representing indebtedness is calculated as the ratio of our total consolidated assets, less all liabilities and indebtedness not represented by senior securities, divided by the aggregate amount of our outstanding debt.

4 For the fiscal quarter ended April 30, 2026, loss on redemption of preferred stock rounds to less than $(0.01) per common share.

5 Weighted based on fair value of total investments as of April 30, 2026. The reinvestment period for loan accumulation facilities is estimated assuming the conversion to a CLO.

6 Calculated as CLO equity and equity-related cash distributions received during the quarter, excluding distributions on CLO equity investments that have been optionally redeemed, divided by average CLO equity and equity-related investments at amortized cost (annualized).

7 Based on amortized cost at period end; excludes discount accretion on CLO debt investments, if applicable.

8 Registration does not imply a certain level of skill or training.
