For Bain Capital Specialty Finance, Inc. specifically, the reported figure for Total Assets as of September 30, 2025, is stated as $2.71 Billion. However, the reported Total Net Assets for BCSF as of September 30, 2025, was $1.1 billion.

Bain Capital Specialty Finance, Inc. (BCSF) - Canvas Business Model: Value Propositions

You're looking at Bain Capital Specialty Finance, Inc. (BCSF) as a provider of capital, and the value it offers to its borrowers and its own investors is quite distinct. For the middle-market companies needing financing, the proposition is about getting exactly the right kind of debt structure, not just a standard loan.

Customized Secured Debt Financing for Middle-Market Firms

Bain Capital Specialty Finance, Inc. focuses on direct originations of secured debt for middle-market companies. This isn't one-size-fits-all lending; it's about tailoring the financing package. The types of debt they originate include:

• Second lien debt

As of March 31, 2025, approximately 64.2% of Bain Capital Specialty Finance, Inc.'s total investment portfolio at fair value was invested in first lien debt. The median EBITDA for the portfolio companies was $42 million as of that same date, with a median leverage multiple of 4.8x. Plus, 92% of their debt investments include financial covenants, which speaks to the protective nature of the financing provided.

Access to Bain Capital's Operational Expertise

This connection means borrowers potentially gain access to the deep experience and resources of the entire Bain Capital network, which is a significant value-add beyond just the capital itself.

High Current Income for Investors

For you, the investor, the primary value proposition is generating high current income. The firm targets this through its investment objective of current income first, and capital appreciation second. The numbers show this focus:

The firm declared a quarterly base cash dividend of $0.42 per share, which annualizes to an 11.7% dividend yield. There was also a supplemental payment of $0.03 per share, which annualized for an incremental 0.84% yield. You should note that the base dividend coverage weakened, with Net Investment Income (NII) per share at $0.45 for Q3 2025, covering the base dividend by 107%.

Portfolio of Predominantly First Lien Senior Secured Loans

The structure of the assets underpinning this income is a key value component, emphasizing security. Bain Capital Specialty Finance, Inc. emphasizes its portfolio is made up of predominantly first lien senior secured loans. This suggests a focus on the most senior part of the capital structure, which generally carries lower risk relative to subordinated debt or equity.

• First Lien Senior Secured Loans: 64.2% of total investment portfolio at fair value (as of March 31, 2025)
• Senior Secured Debt (excluding first lien): 0.8% of total investment portfolio at fair value (as of March 31, 2025)
• Total Senior Secured Debt: 65.0% (64.2% + 0.8%)
• Investments on non-accrual: 1.4% of total investment portfolio at amortized cost (as of March 31, 2025)

Disciplined Investment Approach for Risk-Adjusted Returns

Corrective action, when necessary, can include raising interest rates, gaining influential board roles, or restructuring the balance sheet. The focus on quality is reflected in the portfolio composition:

• 99.7% of the SLP investment portfolio (a segment of the overall portfolio) was in first lien senior secured loans as of September 30, 2025.

Bain Capital Specialty Finance, Inc. (BCSF) - Canvas Business Model: Revenue Streams

You're looking at the top-line drivers for Bain Capital Specialty Finance, Inc. (BCSF) as of late 2025. The primary engine is the yield on their debt portfolio, but they layer in other sources to keep the Net Investment Income (NII) robust.

The total investment income, which serves as the main revenue proxy, for the third quarter ended September 30, 2025, was reported at $67.2 million. This was a sequential step down from the $71.0 million recorded in Q2 2025, with management citing lower other income activity as a factor in the Q3 figure. The core of this income is interest, as the portfolio weighted average yield on debt investments stood at 11.1% at amortized cost and 11.2% at fair value as of the end of Q3 2025. Remember, the vast majority of BCSF's income is contractual cash interest from their debt holdings.

The other components of the revenue stream include various fees, though specific dollar amounts for these are often bundled into the total investment income or referenced qualitatively.

• Fee income streams include origination fees collected when new loans are made.
• Structuring fees are also a component of the upfront revenue capture.
• Prepayment fees are collected when borrowers pay off debt ahead of schedule.

Income derived from strategic joint ventures is a key area, showing the scale of their co-investment strategy. As of September 30, 2025, the fair value of their stakes in these vehicles was substantial, even though the specific income contribution isn't broken out in the total investment income figure.

Here's a look at the reported fair value of the investments in those key vehicles at the end of Q3 2025:

Finally, capital gains on investment exits are less frequent but can impact the bottom line significantly. For the three months ended September 30, 2025, Bain Capital Specialty Finance, Inc. actually recorded net realized and unrealized losses of $10.5 million, which weighed on the net income for the period, even though the Net Investment Income (NII) per share of $0.45 covered the regular dividend.
