Executive Summary / Key Takeaways

• Stellus Capital Investment Corporation ($SCM) is a business development company focused on providing debt and equity financing to U.S. lower middle-market companies, primarily through first lien unitranche loans and equity co-investments.
• The company achieved significant portfolio growth, surpassing the $1 billion mark shortly after Q1 2025, driven by active origination and follow-on activity, despite some recent M&A slowdown attributed partly to tariff uncertainty.
• While Q1 2025 Net Investment Income ($0.35/share GAAP) was slightly below the $0.40 quarterly dividend, management expects to maintain the dividend rate throughout 2025, supported by substantial spillover income ($45 million entering the year) and anticipated equity realization gains (projected >$10 million by year-end 2025).
• SCM maintains a robust capital structure, including a flexible Credit Facility, access to lower-cost SBA debentures (pursuing a third license), and an active ATM program issuing shares above NAV, providing ample liquidity to fund growth and commitments while operating below target leverage levels.
• The company's competitive edge lies in its extensive network and direct origination model, fostering strong relationships and enabling efficient deal sourcing, although it faces competition from larger, more technologically advanced peers.

Setting the Scene: Navigating the Lower Middle Market

Stellus Capital Investment Corporation operates within the dynamic landscape of U.S. middle-market private credit, specifically targeting the lower end of this spectrum – companies typically generating between $5 million and $50 million in EBITDA. Since commencing operations in late 2012, SCM has established itself as a provider of flexible financing solutions, primarily focusing on originating and investing in debt, often complemented by equity co-investments. Its core strategy revolves around building long-term relationships with financial sponsors and management teams to source investment opportunities.

The competitive environment in this space is populated by a diverse set of players, including larger business development companies like Ares Capital Corporation (ARCC), Golub Capital BDC (GBDC), and Owl Rock Capital Corporation (OBDC), as well as other private credit funds and traditional financial institutions. While larger peers often benefit from greater scale and broader market reach, SCM differentiates itself through a focused approach and a relationship-driven origination model. This allows SCM to identify and execute deals within its specific target market, fostering loyalty and potentially accessing opportunities that may be overlooked by larger, less specialized firms.

SCM's strategic evolution has seen a notable shift over the past four to five years towards first lien unitranche secured lending. This approach, often combined with equity co-investments, aligns with the increasing preference among private equity clients for simplified, one-stop financing solutions. This focus also serves a risk management purpose, prioritizing senior secured positions in the capital structure over more junior debt.

Differentiation in a Relationship-Driven Market

Unlike some competitors who leverage advanced digital tools and AI for deal evaluation, SCM's primary differentiation stems from its extensive network and direct origination capabilities. This relationship-based model is a core operational strength, enabling what management describes as efficient deal sourcing. This approach fosters strong ties with financial sponsors and portfolio companies, contributing to customer loyalty and potentially generating recurring revenue streams.

While SCM does not highlight proprietary technology as a competitive moat, its ability to effectively source and manage investments through established relationships serves a similar function within its target market. This contrasts with peers like OBDC, which are noted for using AI-driven analytics to potentially speed up deal evaluation. SCM's model, however, emphasizes the human element of private credit, relying on deep industry knowledge and trusted partnerships built over time.

The company's strategic focus on a debt-equity hybrid model, particularly through equity co-investments alongside its debt financing, is another key differentiator. Management believes this approach offers the potential for meaningful upside beyond the contractual interest income from debt. Historical results from this part of the portfolio indicate realizations in excess of two times cost, highlighting the potential value creation embedded in this strategy.

Financial Performance and Asset Quality

SCM's financial performance reflects the dynamics of its investment portfolio and the prevailing market conditions. For the three months ended March 31, 2025, the company reported total investment income of $24.95 million, a decrease from $26.00 million in the same period of 2024. This decline was primarily attributed to lower prevailing market interest rates (SOFR) impacting its predominantly floating-rate loan portfolio, as well as a decrease in non-recurring income from early repayments and amendments.

Operating expenses for Q1 2025 decreased to $15.16 million (net of fee waivers) from $15.76 million in Q1 2024. This was largely due to an income incentive fee waiver, partially offset by higher management fees and interest expense driven by portfolio growth. Net investment income for the quarter stood at $9.79 million, or $0.35 per share (GAAP), slightly below the $0.40 quarterly dividend rate.

The portfolio experienced a net realized loss of $5.97 million in Q1 2025, significantly lower than the $20.38 million realized loss in Q1 2024. Net change in unrealized appreciation was $1.19 million, a notable decrease from $23.52 million in the prior year period. These changes in valuation were influenced by company-specific factors within the portfolio.

Asset quality is monitored using a five-level rating system. As of March 31, 2025, 52% of the portfolio (by fair value) was rated 2 or higher (on or ahead of plan), while 21% was rated 3 or below (not meeting plan). The number of portfolio companies on non-accrual status decreased to five as of March 31, 2025, representing 6.7% of the loan portfolio at cost and 4.0% at fair value, an improvement from seven companies in the prior quarter.

Comparing SCM's recent TTM financial margins to peers, SCM's Gross Profit Margin (55.17%), Operating Profit Margin (21.87%), and Net Profit Margin (33.84%) appear lower than those of larger peers like ARCC, GBDC, and OBDC, suggesting that scale and potentially operational efficiency or funding costs play a role in profitability differences.

Capital Structure and Liquidity

SCM maintains a diversified and flexible capital structure designed to support its investment activities and meet liquidity needs. Key funding sources include a senior secured revolving Credit Facility, SBA-guaranteed debentures, and unsecured Notes Payable.

The Credit Facility provides committed borrowings up to $315 million (with an accordion to $350 million) and bears floating interest rates. As of March 31, 2025, $221.81 million was outstanding, and the balance was reduced to $147.50 million by May 12, 2025, following the issuance of new notes. The company was in compliance with all Credit Facility covenants.

Access to SBA-guaranteed debentures through its SBIC licenses is a significant advantage, providing lower-cost, fixed-rate funding with 10-year maturities. The company has exemptive relief allowing it to exclude this debt from its asset coverage test, enhancing borrowing capacity. As of March 31, 2025, $308.75 million in SBA debentures were outstanding. The company recently received a "green light" for a third SBIC license, signaling its intent to continue leveraging this favorable funding source as existing debentures mature. Management notes that these debentures, based on current rates, are expected to be priced below 5%, offering a significant cost advantage compared to other borrowings.

Unsecured debt includes $100 million of 4.88% fixed-rate notes due March 2026. To manage upcoming maturities and provide additional funding, SCM issued $75 million of 7.25% Notes due 2030 on April 1, 2025.

The company also utilizes an At-The-Market (ATM) program to issue common stock. In Q1 2025, 656,085 shares were issued for $9.26 million, all at prices above net asset value, demonstrating accretive capital raising.

As of March 31, 2025, SCM's asset coverage ratio was 216%, well above the 150% regulatory requirement. Management indicates they are operating at a lower leverage level than their target (regulatory 1:1, GAAP >2:1) and intend to increase leverage over time to support portfolio growth. Unfunded commitments totaled $46.18 million in debt and $0.29 million in equity as of March 31, 2025, and the company maintains sufficient liquidity to meet these obligations.

Outlook and Growth Drivers

Management is optimistic about the potential for continued portfolio growth, targeting a level around $985 million by the end of Q2 2025 and expressing confidence in the ability to grow the portfolio beyond $1 billion given the current capital base. While the pipeline experienced some temporary slowness related to M&A activity and tariff uncertainty in early 2025, management expects activity to pick up as clarity emerges. New originations are expected to be balanced by repayments in Q2 2025.

A key driver for total return is the potential for realized gains from the equity co-investment portfolio. Management projects more than $10 million in equity gains by year-end 2025, building on realized gains in prior quarters. This potential upside is a significant component of the investment thesis, complementing the income generated from the debt portfolio.

The quarterly dividend is expected to remain at $0.40 per share, payable monthly, throughout 2025. While NII alone may not fully cover the dividend based on current rate and spread environments, the substantial spillover income carried forward ($45 million) and anticipated equity realizations are expected to support the distribution level and potentially result in realized earnings exceeding the dividend for the year.

Risks and Challenges

Investing in SCM involves several risks. The portfolio's sensitivity to interest rate fluctuations is a key factor, although mitigated by interest rate floors on floating-rate loans. A significant downward movement in rates could negatively impact interest income, while upward movements could increase interest expense on floating-rate liabilities, although the SBA debentures provide a fixed-rate component.

Credit risk remains inherent in the portfolio, as evidenced by loans on non-accrual status. While the non-accrual rate decreased in Q1 2025, these situations require active management and can impact income and asset values. Economic developments, including supply chain issues, labor shortages, inflation, and geopolitical instability, could adversely affect the performance of portfolio companies.

Management also highlighted the potential impact of tariffs, which caused some recent M&A slowdown and could affect up to 10% of the portfolio depending on specific outcomes. While currently viewed as a temporary disruption, the uncertainty adds a layer of risk to the investment outlook. Competition in the middle-market lending space could intensify, potentially impacting yields and deal flow.

Conclusion

Stellus Capital Investment Corporation presents a compelling investment thesis centered on its focused approach to the U.S. lower middle-market, combining senior secured debt with meaningful equity upside potential. The company's historical performance, strategic shift towards first lien unitranche lending, and relationship-driven origination model position it effectively within its niche. While recent Net Investment Income has faced headwinds from lower base rates and spread compression, the company's robust capital structure, including access to favorable SBA financing and accretive equity issuance, provides a solid foundation for growth.

The outlook for portfolio expansion beyond $1 billion and the potential for significant equity realization gains in 2025 are key catalysts for total return. Supported by a substantial cushion of spillover income, the company aims to maintain its attractive dividend level. Investors should weigh the potential for income generation and capital appreciation against inherent risks such as interest rate sensitivity, credit quality fluctuations, and the impact of broader economic and geopolitical factors, including tariff-related uncertainty. SCM's ability to execute on its growth strategy and realize value from its equity portfolio will be critical factors to monitor.
