Carlyle Secured Lending, Inc.
Carlyle Secured Lending, Inc. is a closed-end, externally managed business development company that provides secured financing to U.S. middle market companies. Its core mandate is to generate current income, with some capital appreciation, by originating first lien, unitranche, and second lien loans, mainly to sponsor-backed borrowers. The company is advised by an affiliate of Carlyle and benefits from the broader Carlyle Global Credit platform, which gives it access to origination, underwriting, and structuring resources across private credit markets. It has operated as a BDC since 2013 and trades on Nasdaq under the ticker CGBD.

Business
Share of revenueCore secured lending to U.S. middle market borrowers, including first lien and unitranche structures.
Higher-yielding secured and subordinated credit positions used to enhance portfolio income.
Selective investments in unsecured debt, structured products, and other complementary credit assets.
Minority equity or equity-like positions that may accompany lending transactions.
Customers
The company lends primarily to U.S. middle market businesses, typically companies with about $25 million to $100 million of EBITDA. Many of these borrowers are sponsored by private equity firms, which use Carlyle Secured Lending for acquisition financing, recapitalizations, and growth capital. The company also serves borrowers that need customized capital structures across the debt stack, including first lien, unitranche, and second lien solutions. Its customer base is therefore defined less by industry and more by sponsor backing, leverage profile, and the need for flexible private credit execution.
Sponsor-backed U.S. companies that borrow for buyouts, refinancings, and growth initiatives using secured loans.
Businesses with roughly $25 million to $100 million of EBITDA that need private credit rather than syndicated public debt.
Companies that require a mix of first lien, unitranche, second lien, or subordinated debt to complete a financing package.
Smaller allocations to higher-yielding or structured investments used to diversify income and risk.
Strategy
The company’s strategy is to originate secured debt directly and focus on higher-quality senior lending to sponsor-backed middle market borrowers. It uses Carlyle’s broader Global Credit platform to source opportunities, underwrite risk, and offer a wider range of capital solutions than a standalone lender could typically provide. Management emphasizes disciplined credit selection, with a multi-gate underwriting process and a very low closing rate on reviewed transactions, which supports portfolio quality. The strategy also includes selective use of complementary lending and investing activities to diversify returns while preserving the core income-oriented profile.
Direct sourcing improves control over underwriting, pricing, and portfolio composition.
The business depends on avoiding losses in below-investment-grade loans while generating current income.
Access to broader credit capabilities helps win deals and structure one-stop capital solutions.
Geography
Carlyle Secured Lending is overwhelmingly U.S.-focused, with its core lending strategy centered on private U.S. middle market companies. The company is headquartered in New York and operates as a U.S. regulated investment company, so its business, tax, and regulatory profile are anchored in the United States. While the broader Carlyle platform is global, the lending portfolio described in the filings is primarily domestic and tied to U.S. sponsor-backed borrowers. This geographic concentration means performance is driven mainly by U.S. credit conditions, interest rates, and middle market M&A activity rather than international demand.
Risks
The company is exposed to credit losses because it lends to below-investment-grade middle market borrowers, many of which are highly leveraged and sponsor-owned. Rising defaults, weaker sponsor activity, or a slowdown in U.S. M&A can reduce origination volume and pressure portfolio performance. As a BDC, it also faces leverage, asset coverage, and capital-raising constraints that can affect growth and shareholder returns. In addition, the externally managed structure creates conflicts of interest and dependence on Carlyle’s systems, personnel, and information barriers, while cybersecurity and operational failures could disrupt investment activity or portfolio monitoring.
