It has elected to be regulated as a business development company (BDC) under the Investment Company Act of 1940, as amended. The company’s stated investment objective is to generate current income and, to a lesser extent, capital appreciation.

BCSF is managed by BCSF Advisors, L.P., an SEC-registered investment adviser and a subsidiary of Bain Capital Credit, L.P. According to multiple company disclosures, BCSF commenced investment operations on October 13, 2016. Since then, it has invested several billions of dollars in aggregate principal amount of debt and equity investments prior to any subsequent exits or repayments, as reported in its press releases at various dates.

Business model and investment focus

BCSF’s investment strategy centers on the direct origination of secured debt to middle-market borrowers. The company describes its focus as lending to middle-market companies and highlights secured lending as a core activity. Its investment objective is pursued primarily through direct originations of secured debt, including first lien, first lien/last out, unitranche and second lien debt. In addition to these secured loans, BCSF also invests in strategic joint ventures, equity investments and, to a lesser extent, corporate bonds.

BCSF’s portfolio, as described in its financial results releases, consists of a mix of first lien senior secured loans, second lien senior secured loans, subordinated debt, preferred equity, equity interests, warrants and interests in investment vehicles. Over time, the company has reported a portfolio diversified across numerous portfolio companies and industries. The company also holds subordinated notes and equity interests in investment vehicles such as ISLP and SLP, which are described as investment vehicles with portfolios largely composed of first lien senior secured loans and, to a smaller extent, second lien loans and equity interests.

Regulatory status and structure

BCSF has elected to be regulated as a BDC, which affects how it invests and distributes income. As a BDC, it is subject to specific regulatory requirements under the Investment Company Act of 1940. The company’s common stock, with a par value of $0.001 per share, is listed on the New York Stock Exchange under the trading symbol BCSF, as noted in its Form 8-K filings.

The company is externally managed, meaning day-to-day investment decisions and portfolio management are carried out by its investment adviser, BCSF Advisors, L.P. BCSF Advisors is a subsidiary of Bain Capital Credit, L.P., and is registered with the SEC as an investment adviser. BCSF also serves as portfolio manager to certain investment vehicles, including BCC Middle Market CLO 2019-1, Ltd., as described in its 8-K relating to a CLO reset transaction.

Portfolio composition and investment vehicles

BCSF’s financial results releases provide detail on its portfolio composition at various reporting dates. The portfolio is described as being invested across a large number of portfolio companies and industries. Investment types disclosed include:

• First Lien Senior Secured Loans
• Second Lien Senior Secured Loans
• Subordinated Debt
• Preferred Equity
• Equity Interests
• Warrants
• Investment Vehicles, including subordinated notes and equity interests in ISLP and SLP

As of several reporting dates, the company has reported that a significant majority of its debt investments at fair value are in floating rate securities. It has also disclosed that investments on non-accrual status represent a relatively small percentage of the total investment portfolio at amortized cost and fair value at those times.

BCSF also participates in collateralized loan obligation (CLO) structures through its consolidated subsidiaries. For example, an 8-K dated July 7, 2025 describes a refinancing (CLO reset transaction) of a term debt securitization known as BCC Middle Market CLO 2019-1, Ltd. In that transaction, the CLO issuers, which are indirect, wholly owned consolidated subsidiaries of BCSF, issued replacement notes backed by a diversified portfolio of middle-market commercial loans. BCSF continues to serve as portfolio manager to the CLO issuer and retains interests in the CLO for regulatory retention purposes.

Capital structure, dividends and financing

BCSF’s capital structure includes a combination of credit facilities and unsecured notes. In its periodic financial results announcements, the company reports total principal debt outstanding, which has included borrowings under the Sumitomo Credit Facility, debt issued through BCC Middle Market CLO 2019-1 LLC, and senior unsecured notes with stated maturities in 2026 and 2030. For example, the company has disclosed offerings of senior unsecured notes due 2030 with a stated coupon rate, and has entered into interest rate swap agreements in connection with those notes.

The company regularly declares cash dividends on its common stock. Press releases and related Form 8-K filings describe quarterly dividends and, at times, additional or special dividends. For instance, BCSF has announced quarterly dividends of $0.42 per share for various quarters in 2025, along with additional dividends of $0.03 per share per quarter for 2025, and a special dividend of $0.15 per share intended to manage tax and RIC distribution requirements. These dividends are described as being supported by net investment income and the company’s capital management approach.

Financial reporting and performance indicators

BCSF reports financial results on a quarterly and annual basis, including net investment income, net income per share, net asset value per share, total assets, total fair value of investments and total net assets. The company highlights metrics such as:

• Net investment income (NII) per share and annualized NII yield on book value

• Net asset value (NAV) per share

These disclosures give investors insight into the company’s investment activity, portfolio diversification and credit performance over time.

Management and governance disclosures

Form 8-K filings provide information on certain management and governance events. For example, an 8-K dated November 5, 2025 reports the appointment of a new General Counsel of the company, and an 8-K dated June 30, 2025 notes the resignation of a Vice President and the appointment of a successor. These filings indicate that the company makes public disclosures regarding changes in key officers and related governance matters.

Use of securitizations and joint ventures

BCSF’s strategy includes the use of securitizations and investment vehicles to finance and hold portions of its loan portfolio.

The company also discloses that it continues to act as retention holder in connection with that CLO, in order to satisfy regulatory requirements in multiple jurisdictions.

In addition, BCSF’s portfolio includes subordinated notes and equity interests in investment vehicles referred to as ISLP and SLP.
