What Golub Capital BDC does
Golub Capital BDC, Inc. (NASDAQ: GBDC) is an externally managed, publicly traded business development company that provides senior debt capital to U.S. middle market companies controlled by private equity sponsors. The company is advised by GC Advisors LLC, an affiliate of Golub Capital, and as of March 31, 2026 held a portfolio of 420 investments with an aggregate fair value of approximately $8.3 billion, of which roughly 92% was structured as first lien senior secured loans. GBDC pursues a granular, sponsor-relationship-driven origination model, evidenced by 300+ repeat sponsor relationships and 390+ incumbent lender relationships at the platform level, and an average position size of approximately 0.2% of portfolio.
The business model is straightforward spread-based lending: GBDC earns interest income on its loan portfolio funded with a mix of secured bank facilities, unsecured public notes (with multiple issuances priced between 6.0% and 7.05%), and equity capital, with a weighted average cost of debt of 5.2%. Revenue is therefore a function of portfolio size, base rate level, and net spread. The company has scaled materially over the past five years, with annual revenue growing from $307M in 2021 to $870.77M in 2025, and runs a parallel private placement vehicle branded GCRED to broaden its funding and distribution footprint. The platform is supported by 230+ investment professionals within a 1,100+ person organization, with $90B+ in assets under management at the parent Golub Capital platform.
GBDC holds a three-agency investment-grade rating profile (Moody's Baa2, Fitch BBB, S&P BBB-) and is governed under the regulated investment company/BDC regime, which constrains leverage, asset composition, and distribution policy. The sub-brand GCRED and geographic presence spanning North America, Europe, Asia, and the Middle East indicate an ongoing channel and origination diversification beyond the public BDC vehicle. Leadership continuity was reinforced when David Golub was elevated to Chairman in November 2025.
