<sup>1 &nbsp;&nbsp;&nbsp;&nbsp;</sup>On September 16, 2019 and June 3, 2024, the Company completed its acquisition of Golub Capital Investment Corporation ("GCIC") and Golub Capital BDC 3, Inc. ("GBDC 3"), respectively. Each acquisition was accounted for under the asset acquisition method of accounting in accordance with Accounting Standards Codification 805-50, Business Combinations — Related Issues. Under asset acquisition accounting, where the consideration paid to GCIC and GBDC 3's stockholders exceeded the relative fair values of the assets acquired, the premium paid by the Company was allocated to the cost of the GCIC and GBDC 3 investments acquired by the Company pro-rata based on their relative fair value. Immediately following each acquisition, the Company recorded its assets at their respective fair values and, as a result, the purchase premium allocated to the cost basis of the assets acquired was immediately recognized as unrealized depreciation on the Company's Consolidated Statement of Operations. The purchase premium allocated to investments in loan securities acquired from GCIC and GBDC 3 will amortize over the life of the loans through interest income with a corresponding reversal of the unrealized depreciation on such loans acquired through their ultimate disposition. The purchase premium allocated to investments in equity securities will not amortize over the life of the equity securities through interest income and, assuming no subsequent change to the fair value of the GCIC and GBDC 3 equity securities acquired and disposition of such equity securities at fair value, the Company will recognize a realized loss with a corresponding reversal of the unrealized depreciation upon disposition of the GCIC and GBDC 3 equity securities acquired.

As a supplement to U.S. generally accepted accounting principles ("GAAP") financial measures, the Company is providing the following non-GAAP financial measures that it believes are useful for the reasons described below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• "Adjusted Net Investment Income"** and **"Adjusted Net Investment Income Per Share"** – excludes the amortization of the purchase premium from net investment income calculated in accordance with GAAP.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **"Adjusted Net Investment Income Before Accrual for Capital Gain Incentive Fee**" – Adjusted Net Investment Income excluding the accrual or reversal for the capital gain incentive fee required under GAAP;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• "Adjusted Net Realized and Unrealized Gain/(Loss)"** and **"Adjusted Net Realized and Unrealized Gain/(Loss) Per Share"** – excludes the unrealized loss resulting from the purchase premium write-down and the corresponding reversal of the unrealized loss from the amortization of the premium from the determination of realized and unrealized gain/(loss) in accordance with GAAP.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• "Adjusted Net Income/(Loss)"** and **"Adjusted Earnings/(Loss) Per Share"** – calculates net income and earnings per share based on Adjusted Net Investment Income and Adjusted Net Realized and Unrealized Gain/(Loss).

------

Exhibit 99.1

The Company believes that excluding the financial impact of the purchase premium write down in the above non-GAAP financial measures is useful for investors as it is a non-cash expense/loss resulting from the acquisitions of GCIC and GBDC 3 and is one method the Company uses to measure its financial condition and results of operations. In addition, the Company believes excluding the accrual of the capital gain incentive fee under GAAP is useful as a portion of such accrual is not contractually payable under the terms of the Company's investment advisory agreement with GC Advisors.

**Fourth Fiscal Quarter 2025 Highlights**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net investment income per share for the quarter ended September 30, 2025 remained consistent at $0.38 compared to the quarter ended June 30, 2025. Excluding $0.01 per share in purchase premium amortization from the GCIC/GBDC 3 acquisitions, and no accrual or reversal for the capital gain incentive fee under GAAP, Adjusted Net Investment Income Per Share<sup>1</sup> for the quarters ended September 30, 2025 and June 30, 2025 was $0.39.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net realized and unrealized gain/(loss) per share for the quarter ended September 30, 2025 was ($0.02). Adjusted Net Realized and Unrealized Gain/(Loss) Per Share<sup>1</sup> was ($0.03) when excluding $0.01 per share net reversal of unrealized depreciation and realized loss resulting from the amortization of the purchase premium. The Adjusted Net Realized and Unrealized Gain/(Loss) Per Share<sup>1</sup> for the quarter ended September 30, 2025 was primarily due to (i) unrealized depreciation resulting from the underperformance of certain portfolio companies and (ii) net realized losses recognized on the restructuring of three portfolio company investments and the sale of a portfolio company investment that was partially offset by (i) a realized gain recognized on the disposition of an equity investment in a portfolio company and (ii) net realized and unrealized gains recognized on the translation of foreign currency transactions. For additional analysis, please refer to the Quarter Ended 09.30.2025 Earnings Presentation available on the Investor Resources link on the homepage of the Company's website (www.golubcapitalbdc.com) under Events/Presentations. The Earnings Presentation was also filed with the Securities and Exchange Commission as an exhibit to a Form 8-K. These results compare to net realized and unrealized gain/(loss) per share of ($0.04) during the quarter ended June 30, 2025. Adjusted Net Realized and Unrealized Gain/(Loss) Per Share<sup>1</sup> for the quarter ended June 30, 2025 was ($0.05) when excluding $0.01 per share net reversal of unrealized depreciation and realized loss resulting from the amortization of the purchase premium.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Earnings per share for the quarter ended September 30, 2025 was $0.36 as compared to $0.34 for the quarter ended June 30, 2025. Adjusted Earnings Per Share<sup>1</sup> for the quarter ended September 30, 2025 was $0.36 as compared to $0.34 for the quarter ended June 30, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net asset value ("NAV") per share decreased to $14.97 at September 30, 2025 from $15.00 at June 30, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• On September 29, 2025, we paid a quarterly distribution of $0.39 per share.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• On November 14, 2025, our board of directors declared a quarterly distribution of $0.39 per share, which is payable on December 30, 2025, to stockholders of record as of December 12, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• During the three months ended September 30, 2025, we opportunistically repurchased approximately 368,333 shares of our common stock for an aggregate purchase price of approximately $5.2 million, at an aggregate price of $14.02 per share, and during the period October 1, 2025 through November 18, 2025 we repurchased approximately 2.5 million shares of our common stock for an aggregate purchase price of approximately $34.8 million, at an aggregate price of $13.69 per share in response to market volatility. During the fiscal year ended September 30, 2025, we repurchased approximately $40.6 million, or 2.9 million shares, of our common stock pursuant to the Company's previously disclosed share repurchase program.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• During the three months ended September 30, 2025, the Golub Capital Employee Grant Program Rabbi Trust (the "Trust") purchased approximately $8.1 million, or 551,971 shares, of our common stock for the purpose of awarding incentive compensation to employees of Golub Capital. Through the first three calendar quarters of 2025, the Trust purchased $33.5 million, or 2,243,259 shares, of our common stock.

| Equity | 646282 | 7.4 | 629847 | 7.0 |
| Total | $8769389 | 100.0% | $8961549 | 100.0% |

---

<sup>\*</sup> Junior debt is comprised of second lien and subordinated debt.

The following table shows the asset mix of our new investment commitments for the three months ended September 30, 2025:

---

| | | |
|:---|:---|:---|
| | **New Investment**<br>**Commitments**<br>**(In thousands)** |<br>**Percentage of**<br>**Commitments** |
| Senior secured | $2000 | 2.3% |
| One stop | 80377 | 92.9 |
| Junior debt<sup>\*</sup> | 1171 | 1.4 |
| Equity | 2942 | 3.4 |
| Total new investment commitments | $86490 | 100.0% |

---

<sup>\*</sup> Junior debt is comprised of second lien and subordinated debt.

Total investments in portfolio companies at fair value were $8,769.4 million at September 30, 2025. As of September 30, 2025, total assets were $8,978.3 million, net assets were $3,982.6 million and net asset value per share was $14.97.

**Consolidated Results of Operations**

For the fourth fiscal quarter of 2025, the Company reported GAAP net income of $96.3 million or $0.36 per share and Adjusted Net Income<sup>2</sup> of $96.3 million or $0.36 per share. GAAP net investment income was $100.8 million or $0.38 per share and Adjusted Net Investment Income<sup>1</sup> was $104.3 million or $0.39 per share. GAAP net realized and unrealized gain/(loss) was ($4.6) million or ($0.02) per share and Adjusted Realized and Unrealized Gain/(Loss)<sup>1</sup> was ($8.2) million or ($0.03) per share.

Net income can vary substantially from period to period due to various factors, including the level of new investment commitments, the recognition of realized gains and losses and unrealized appreciation and depreciation. As a result, quarterly comparisons of net income may not be meaningful.

**Liquidity and Capital Resources**

The Company's liquidity and capital resources are derived from the Company's debt securitizations (also known as collateralized loan obligations, or CLOs), unsecured notes, revolving credit facilities and cash flow from operations. The Company's primary uses of funds from operations include investments in portfolio companies and payment of fees and other expenses that the Company incurs. The Company has used, and expects to continue to use, its debt securitizations, unsecured notes, revolving credit facilities, proceeds from its investment portfolio and proceeds from offerings of its securities and its dividend reinvestment plan to finance its investment objectives.

As of September 30, 2025, we had cash, cash equivalents and foreign currencies of $23.6 million, restricted cash and cash equivalents and restricted foreign currencies of $88.8 million and $4,926.8 million of debt outstanding. As of September 30,

<sup>2</sup> See footnote 1 to "Selected Financial Highlights" above.

Exhibit 99.1

2025, subject to leverage and borrowing base restrictions, we had approximately $899.1 million of remaining availability, in the aggregate, on our revolving credit facility with JPMorgan. In addition, as of September 30, 2025, we had $260.8 million of remaining commitments and availability on our unsecured line of credit with GC Advisors.

On September 19, 2025, we issued an additional $250.0 million of 2028 Unsecured Notes, which bear a fixed interest rate of 7.050% (yield to maturity of 5.050%). In connection with the additional 2028 Notes, we entered into an interest rate swap agreement on the additional $250 million principal amount of the additional 2028 Notes where we receive a fixed interest rate of 5.050% and pay a floating interest rate of Daily SOFR plus 1.723%.

The Company's GAAP leverage ratio decreased to 1.25x as of September 30, 2025 and our GAAP debt-to-equity ratio, net<sup>3</sup> decreased to 1.23x as of September 30, 2025 (1.23x, on average, throughout the quarter ended September 30, 2025).

**Portfolio and Asset Quality** 

GC Advisors regularly assesses the risk profile of each of the Company's investments and rates each of them based on an internal system developed by Golub Capital and its affiliates. This system is not generally accepted in our industry or used by our competitors. It is based on the following categories, which we refer to as GC Advisors' internal performance ratings:

---

| | |
|:---|:---|
| **Internal Performance Ratings** | **Internal Performance Ratings** |
| **Rating** | **Definition** |
| **5** | Involves the least amount of risk in our portfolio. The borrower is performing above expectations, and the trends and risk factors are generally favorable. |
| **4** | Involves an acceptable level of risk that is similar to the risk at the time of origination. The borrower is generally performing as expected, and the risk factors are neutral to favorable. |
| **3** | Involves a borrower performing below expectations and indicates that the loan's risk has increased somewhat since origination. The borrower could be out of compliance with debt covenants; however, loan payments are generally not past due. |
| **2** | Involves a borrower performing materially below expectations and indicates that the loan's risk has increased materially since origination. In addition to the borrower being generally out of compliance with debt covenants, loan payments could be past due (but generally not more than 180 days past due). |
| **1** | Involves a borrower performing substantially below expectations and indicates that the loan's risk has substantially increased since origination. Most or all of the debt covenants are out of compliance and payments are substantially delinquent. Loans rated 1 are not anticipated to be repaid in full and we will reduce the fair market value of the loan to the amount we anticipate will be recovered. |

---

Our internal performance ratings do not constitute any rating of investments by a nationally recognized statistical rating organization or represent or reflect any third-party assessment of any of our investments. For additional analysis on the Company's internal performance ratings as of September 30, 2025, please refer to the Quarter Ended 09.30.2025 Earnings Presentation available on Investors Resources link on the homepage of the Company's website (www.golubcapitalbdc.com) under Events/Presentations.

The following table shows the distribution of the Company's investments on the 1 to 5 internal performance rating scale at fair value as of September 30, 2025 and June 30, 2025:

<sup>3</sup> GAAP debt-to-equity, net is calculated as (a) total debt reduced by (i) cash, (ii) cash equivalents and foreign currencies and (iii) restricted cash held for partial repayment on notes of certain of our securitization vehicles past their reinvestment period term (if any) divided by (b) total net assets.
