This focus on the safest part of the capital structure has driven consistent performance. For the full fiscal year ended September 30, 2025, the company reported a total profit of $376.6 million on revenue of $870.8 million.

Given Company's Strategic Advantages

The company's market success stems from a few clear, structural advantages that are tough for competitors to replicate, especially in the volatile middle-market lending space.

• First-Lien Focus: A portfolio composition of 92% in First Lien Senior Secured Debt as of June 30, 2025 provides a significant cushion against credit losses compared to peers.
• Scale and Brand: The affiliation with Golub Capital gives GBDC a competitive edge in pricing and deal flow, often allowing it to lead or co-lead large middle-market transactions.
• Credit Quality: GBDC has maintained low non-accrual rates, with nearly 90% of its investments at fair value carrying an internal performance rating of 4 or higher, reflecting strong credit discipline.
• Investment Grade Rating: GBDC's corporate credit rating was upgraded to Baa2 (Stable) by Moody's in early 2025, which translates to lower borrowing costs and greater financial flexibility.

Here's the quick math: lower cost of debt plus higher-quality, higher-yielding assets equals a wider net investment income spread. This is how GBDC delivered a Net Asset Value (NAV) per share of $14.97 at the close of the 2025 fiscal year.

Golub Capital BDC, Inc. (GBDC) How It Makes Money

Golub Capital BDC, Inc. (GBDC) primarily makes money by originating and holding debt investments, specifically senior secured and one-stop loans, to U.S. middle-market companies, generating the vast majority of its revenue from the interest payments on those loans.

As a Business Development Company (BDC), GBDC operates as a closed-end investment company that invests in privately held companies, passing through most of its income to shareholders as dividends, which is why current income is the core of its financial engine. This is a very straightforward model: borrow money cheaply, lend it at a higher rate, and pocket the spread.

Given Company's Revenue Breakdown

For the quarter ended September 30, 2025, GBDC reported total investment income of $217.84 million. The income streams are overwhelmingly weighted toward interest income from its debt portfolio, a common structure for BDCs focused on senior lending.

Here's the quick math: Interest Income, net of purchase premium amortization, was approximately $208.01 million, making it the defintely dominant stream.

Business Economics

The core of GBDC's business model is providing 'one-stop' financing, which combines senior debt (first lien) and junior debt (second lien/subordinated) into a single loan facility for a middle-market borrower, typically a company backed by a private equity sponsor. This simplifies the capital structure for the borrower and allows GBDC to capture a higher overall yield.

• Floating Rate Advantage: Approximately 100% of GBDC's debt investments bear interest at floating rates, meaning their interest income rises with benchmark rates like SOFR (Secured Overnight Financing Rate).
• Cost of Capital: The company manages its own cost of debt, with a weighted average cost of debt at 5.6% as of September 30, 2025, using a mix of secured and unsecured debt.
• Management Fee Structure: GBDC is externally managed by GC Advisors LLC, which is compensated via a two-part fee: a base management fee (1.0% of gross assets, excluding cash) and an incentive fee (15.0% of Net Investment Income above an 8.0% hurdle rate).
• PIK Interest: A portion of the interest income is Payment-in-Kind (PIK), where interest is added to the loan principal instead of being paid in cash. This represented 5.73% of interest income as of June 30, 2025, a metric to watch as it's non-cash revenue.

The spread between the 9.9% weighted average income yield on investments and the 5.6% cost of debt is the fundamental economic driver, but credit losses are the real risk.

Given Company's Financial Performance

GBDC's financial health as of the end of its fiscal year on September 30, 2025, shows a stable, albeit slightly pressured, picture, reflecting the challenging middle-market credit environment.

• Full-Year Revenue: Total Investment Income for the fiscal year 2025 was $870.8 million, a significant figure driven by the high rate environment and portfolio growth.
• Net Investment Income (NII): NII, the best measure of core profitability for a BDC, was $397.3 million for the fiscal year 2025.
• Net Asset Value (NAV) per Share: NAV per share was $14.97 as of September 30, 2025, a slight decrease from the prior quarter, which is a key indicator of portfolio valuation stability.
• Leverage: The GAAP debt-to-equity ratio, net, was 1.23x as of September 30, 2025, which is within the company's target range of 0.85x to 1.25x, showing disciplined balance sheet management.
• Credit Quality: Non-accrual investments-loans where interest payments are significantly past due-decreased to just 0.3% of the total portfolio at fair value as of September 30, 2025, indicating strong portfolio company performance despite market headwinds.
