## Overview

Golub Capital BDC, Inc. is an externally managed, closed-end business development company that provides private credit to U.S. middle-market businesses, often companies backed by private-equity sponsors. Its portfolio is centered on senior secured lending, particularly first-lien and unitranche loans, with selective investments in other debt and equity securities. The company’s stated investment objective is to generate current income and capital appreciation. [1](https://app.finbar.com/go?id=P95168374)[2](https://app.finbar.com/go?id=P34494732)

Formed in 2009, GBDC reported total investment income of approximately $870.8 million for fiscal 2025. It is managed by Golub Capital; the manager reported more than 1,000 employees across its platform as of September 30, 2025, which is not a GBDC-specific employee count.

## Products & services

Golub Capital BDC’s principal offerings are financing structures rather than separately branded products. It invests primarily in “one-stop” loans and other senior-secured loans to U.S. middle-market companies, generally with annual EBITDA below $100 million and often backed by private equity sponsors. One-stop loans combine features of first-lien and second-lien or subordinated debt; they are commonly structured as senior-secured loans with first-priority liens, and Golub or its affiliates may act as the sole lender. [1](https://app.finbar.com/go?id=P95168374)[5](https://app.finbar.com/go?id=P75065742)

Other investments include second-lien and subordinated loans, warrants, and minority equity securities. The stated investment objective is to generate current income and capital appreciation. Intended investment sizes are generally about $10 million to $80 million, with selective investments above that range; many debt investments carry floating interest rates and are below investment grade. [2](https://app.finbar.com/go?id=P34494732)[6](https://app.finbar.com/go?id=P41695067)[7](https://app.finbar.com/go?id=P84262579)

Through its investment adviser, GC Advisors, the company sources and evaluates investment opportunities, conducts due diligence on companies and sponsors, structures investments, and monitors portfolio companies. Its 2026 third-quarter holdings illustrate one-stop and subordinated-debt positions, but the cited information does not provide an aggregate percentage of assets, income, or performance attributable to each product category.

## Geographic presence

Golub Capital BDC focuses on lending to U.S. middle-market companies. Its latest available report, for the quarter ended June 30, 2026, does not provide a country- or region-level breakdown of portfolio or revenue exposure, so the geographic distribution and any regional percentages cannot be determined from that disclosure. [11](https://golubcapitalbdc.com/)[12](https://app.finbar.com/go?id=P145701469)[13](https://app.finbar.com/go?id=T16673689)

Golub Capital’s broader organization lists offices including London, Greenwich, Miami, Seoul, Hong Kong, Tokyo, Abu Dhabi, Dallas and Huntersville; this is the manager’s office footprint, not a BDC-specific office roster. The BDC filing does not disclose employee counts or their geographic distribution. [14](https://golubcapital.com/contact-us/)[15](https://app.finbar.com/go?id=P145701589)

## Business segments

Golub Capital BDC, Inc. reports one operating and reportable segment; it does not disclose separate business-line segments or segment-level contribution percentages. Management assesses performance and makes decisions on a consolidated basis, primarily using net income. Accordingly, portfolio allocations should not be interpreted as contributions from formally reported segments. [16](https://app.finbar.com/go?id=P145700809)[17](https://app.finbar.com/go?id=P145700810)[18](https://app.finbar.com/go?id=P145701684)

As an alternative view of portfolio composition, at June 30, 2026 debt investments represented approximately 92.9% and equity investments 7.1% of the fair value of debt and equity investments combined ($7,612.6 million and $583.7 million, respectively). These percentages are calculated from the reported values and exclude money-market funds. [19](https://app.finbar.com/go?id=T16673813)

The FY2025 investment-type breakdown provides further detail: one-stop investments were approximately 86.8% of total investment fair value, equity 7.4%, senior secured debt 5.0%, subordinated debt 0.4%, and second lien debt 0.3%. These are investment classifications—not operating segments—and the percentages are calculated from reported fair values. [20](https://app.finbar.com/go?id=T11138957)
