On October 12, 2020, we completed our merger (the “Merger”) with Goldman Sachs Middle Market Lending Corp. (“MMLC”). The Merger was accounted for as an asset acquisition in accordance with ASC 805-50, Business Combinations — Related Issues. The consideration paid to MMLC’s shareholders was less than the aggregate fair values of the assets acquired and liabilities assumed, which resulted in a purchase discount (the “purchase discount”). The purchase discount was allocated to the cost of MMLC investments acquired by us on a pro-rata basis based on their relative fair values as of the closing date. Immediately following the Merger with MMLC, we marked the investments to their respective fair values and, as a result, the purchase discount allocated to the cost basis of the investments acquired was immediately recognized as unrealized appreciation on our Consolidated Statement of Operations. The purchase discount allocated to the loan investments acquired will amortize over the life of each respective loan through interest income, with a corresponding adjustment recorded as unrealized appreciation on such loan acquired through its ultimate disposition. The purchase discount allocated to equity investments acquired will not amortize over the life of such investments through interest income and, assuming no subsequent change to the fair value of the equity investments acquired and disposition of such equity investments at fair value, we will recognize a realized gain with a corresponding reversal of the unrealized appreciation on disposition of such equity investments acquired.

As a supplement to our financial results reported in accordance with generally accepted accounting principles in the United States of America (“GAAP”), we have provided, as detailed below, certain non-GAAP financial measures to our operating results that exclude the aforementioned purchase discount and the ongoing amortization thereof, as determined in accordance with GAAP. The non-GAAP financial measures include i) Adjusted net investment income per share; ii) Adjusted net investment income after taxes; and iii) Adjusted net realized and unrealized gains (losses). We believe that the adjustment to exclude the full effect of the purchase discount is meaningful because it is a measure that we and investors use to assess our financial condition and results of operations. Although these non-GAAP financial measures are intended to enhance investors’ understanding of our business and performance, these non-GAAP financial measures should not be considered an alternative to GAAP. The aforementioned non-GAAP financial measures may not be comparable to similar non-GAAP financial measures used by other companies.

The discussion of the investment portfolio excludes the investment, if any, in a money market fund managed by an affiliate of Goldman Sachs Group, Inc. (the “Money Market Fund”). As of March 31, 2026, the Company had an investment of $2.5 million in the Money Market Fund.

Total debt outstanding excludes netting of debt issuance costs of $14.3 million and $8.2 million as of March 31, 2026 and December 31, 2025, respectively. Total debt outstanding also excludes cumulative hedging adjustments for those borrowings that are designated in a fair value hedging relationship of $(8.1) million and $(3.0) million as of March 31, 2026 and December 31, 2025, respectively. Starting in the third quarter of 2025, the Company entered into interest rate swaps to more closely align the interest rates of some of the Company’s fixed rate liabilities with its investment portfolio, which consists of predominately floating rate loans. The Company designated these interest rate swaps as the hedging instrument in a qualifying fair value hedge accounting relationship.

The $0.32 per share Base Dividend is payable on or about July 28, 2026 to shareholders of record as of June 30, 2026.

On February 26, 2025, we announced a distribution framework that is comprised of a quarterly base distribution declared in the relevant quarter and a variable supplemental distribution declared in the following quarter, subject to satisfaction of certain measurement tests and the approval of our Board.

As a supplement, we have provided a non-GAAP financial measure of our financial condition that adjusts the net asset value per share for the declared and unpaid supplemental distribution per share. We believe that the adjustment to the net asset value per share for the supplemental dividend is meaningful because it aligns the supplemental distribution to its relevant quarter earnings.

Although this non-GAAP financial measure is intended to enhance investors’ understanding of our business and performance, this non-GAAP financial measure should not be considered an alternative to GAAP. The aforementioned non-GAAP financial measure may not be comparable to similar non-GAAP financial measures used by other companies.

The fixed versus floating composition has been calculated as a percentage of performing debt investments measured on a fair value basis, including income producing preferred stock investments and excludes investments, if any, placed on non-accrual status.

8)

Computed based on the (a) annual actual interest rate or yield earned plus amortization of fees and discounts on the performing debt and other income producing investments as of the reporting date, divided by (b) the total performing debt and other income producing investments (excluding investments on non-accrual) at amortized cost or fair value, respectively. This calculation excludes exit fees that are receivable upon repayment of the investment. Excludes the purchase discount and amortization related to the Merger.

For a particular portfolio company, we calculate the level of contractual indebtedness net of cash (“net debt”) owed by the portfolio company and compare that amount to measures of cash flow available to service the net debt. To calculate net debt, we include debt that is both senior and pari passu to the tranche of debt owned by us but exclude debt that is legally and contractually subordinated in ranking to the debt owned by us. We believe this calculation method assists in describing the risk of our portfolio investments, as it takes into consideration contractual rights of repayment of the tranche of debt owned by us relative to other senior and junior creditors of a portfolio company. We typically calculate cash flow available for debt service at a portfolio company by taking net income before net interest expense, income tax expense, depreciation and amortization (“EBITDA”) for the trailing twelve month period. Weighted average net debt to EBITDA is weighted based on the fair value of our debt investments and excludes investments where net debt to EBITDA may not be the appropriate measure of credit risk, such as cash collateralized loans and investments that are underwritten and covenanted based on recurring revenue.

For a particular portfolio company, we also compare that amount of EBITDA to the portfolio company’s contractual interest expense. We believe this calculation method assists in describing the risk of our portfolio investments, as it takes into consideration contractual interest obligations of the portfolio company. Weighted average interest coverage is weighted based on the fair value of our performing debt investments and excludes investments where interest coverage may not be the appropriate measure of credit risk, such as cash collateralized loans and investments that are underwritten and covenanted based on recurring revenue.

Median EBITDA is based on our debt investments and excludes investments where net debt-to-EBITDA may not be the appropriate measure of credit risk, such as cash collateralized loans and investments that are underwritten and covenanted based on recurring revenue.

Portfolio company statistics are derived from the financial statements most recently provided to us of each portfolio company as of the reported end date. Statistics of the portfolio companies have not been independently verified by us and may reflect a normalized or adjusted amount. As of March 31, 2026 and December 31, 2025, investments where net debt-to-EBITDA may not be the appropriate measure of credit risk represented 13.7 and 14.2%, respectively, of total debt investments at fair value.

The Company’s Revolving Credit Facility has debt outstanding denominated in currencies other than U.S. Dollars (“USD”). These balances have been converted to USD using applicable foreign currency exchange rates as of March 31, 2026. As a result, the Revolving Credit Facility’s outstanding borrowings and the available debt amounts may not sum to the total debt commitment amount.

The ending net debt-to-equity leverage ratio is calculated by using the total borrowings net of cash and cash equivalents divided by equity as of March 31, 2026 and excludes unfunded commitments.
