CSWC — FY2026 Annual Financial Report Analysis

Capital Southwest is a business development company (BDC): a listed fund that lends to mid-sized private US companies, usually ones earning $3 million to $25 million a year before interest, tax, depreciation and amortization (EBITDA). By law it must pay out nearly all of its taxable income as dividends. In the fiscal year ended March 31, 2026, its loan book grew 17.5% to $2.10 billion and total investment income rose 13.5% to $232.1 million. Lower benchmark interest rates pulled the average yield on its loans down from 11.7% to 10.8%, though, and it issued about 19% more shares on average to fund the growth. As a result, net investment income per share, the recurring earnings that pay the dividend, fell 3.7% to $2.37, while the dividend paid stayed at $2.56. GAAP earnings per diluted share rose 29% to $1.90, but only because the prior year carried $49.7 million of realized losses, mostly from restructured loans.

At a glance

• Net investment income of $2.37 per share, down from $2.46. Total net investment income rose 14.6% to $135.5 million, but the share count grew faster, so each shareholder's slice got smaller.
• Net asset value (NAV) per share of $16.69, against $16.70 a year earlier. NAV per share is what the fund's investments minus its debts are worth for each share. It held flat only because new shares were sold well above NAV; the year's earnings alone did not cover the dividend.
• Non-accruals fell to 1.1% of the portfolio at fair value, from 1.7%. A non-accrual is a loan whose borrower has stopped paying interest. Measured at cost, the share fell from 3.5% to 2.4%.

Results for the year

A BDC's "revenue" is total investment income: interest, fees and dividends from the companies it finances. Its GAAP bottom line, the "net increase in net assets from operations," adds gains and losses on those investments to NII. Those gains and losses swing a lot from year to year, so NII per share is the better guide to whether the dividend can be paid.

Where the growth came from, and why per-share income fell

Interest-type income (cash interest, PIK interest and amortized loan discounts) rose 10.4% to $206.4 million. The filing gives the cause: the average cost of debt investments held grew 20.3%, from $1,487.4 million to $1,789.9 million. That was "partially offset by a decrease in weighted average yield on debt investments from 11.7% to 10.8%... primarily due to a decrease in benchmark interest rates." About 95.5% of its loans carry floating rates, so when the Federal Reserve cuts, the income on each loan dollar falls with it.

Dividend income from portfolio companies almost tripled, from $4.5 million to $12.7 million. That $8.2 million is about 30% of the year's $27.7 million rise in investment income. The filing attributes it only to "an increase in distributions received from portfolio companies," and such payouts are lumpier than loan interest.

Costs moved in both directions. Interest expense rose 21.2% to $66.6 million on $189.6 million more average borrowing, at a flat 5.52% average rate. Other operating costs were flat at $28.9 million, helped by the absence of $2.6 million of one-time pay linked to the former CEO's departure in the prior year. Because the fund is internally managed (it employs its own staff rather than paying an outside manager a fee), costs excluding interest fell to 1.43% of average assets, from 1.73%.

The squeeze shows up per share. The fund sold 7.4 million new shares through its at-the-market program, meaning shares sold into the market over time, at an average of $21.65, raising $157.8 million net. Weighted average shares rose 19.1% to 56.5 million, more than the 14.6% rise in NII. Each dollar of new equity was put to work at a lower yield than the year before.

What the headline numbers hide

• The 60% jump in the GAAP bottom line is mostly a weaker comparison year. FY2025 carried $49.7 million of net realized losses, including $53.2 million from restructured loans. This year's net realized gain was $5.5 million: $36.9 million of gains on equity stakes sold, against $24.5 million of losses on debt from exits ($13.1 million) and restructurings ($11.5 million). Net unrealized depreciation of $25.8 million includes $21.2 million of earlier equity gains that moved from "unrealized" to "realized" when those stakes were sold. Combined, realized and unrealized losses were $20.3 million, against $47.2 million the year before.
• The dividend was not covered by recurring earnings. NII of $2.37 per share covered the $2.32 regular dividend (four quarters of $0.58), about 102%, but not the $2.56 total including the $0.06 quarterly supplemental dividends, about 93%. After investment losses, earnings per basic share were $1.98, or $0.58 below the dividend. NAV per share still held at $16.69 because selling stock about 30% above NAV added $0.57 per share. The fund also has a buffer: an estimated $64.5 million ($1.07 per share) of taxable income earned but not yet paid out, which it can carry forward and pay later.
• Credit quality is mixed underneath the lower non-accrual figure. Non-accruals fell. But the share of debt rated 3 to 5 on the company's 1-to-5 risk scale (5 = most at risk) rose from 10.5% to 12.3%, mainly because rating-3 loans ("performing below underwriting expectations") rose from 9.0% to 10.9%. The share rated 1 (performing best) fell from 25.0% to 18.8%. The average borrower is also smaller, with weighted average EBITDA down from $18.5 million to $15.7 million, and slightly more indebted, at 3.6x debt to EBITDA against 3.5x.
• PIK income is steady, not rising. PIK ("payment in kind") interest is added to the loan balance instead of being paid in cash. It was $14.4 million, about 6.2% of investment income, the same share as the year before.
• Leverage edged up but is well inside the legal limit. Based on the debt principal amounts in the filing, total borrowings were about $1.15 billion against $1.01 billion of net assets, roughly 1.14x debt to equity, up from about 1.10x. Asset coverage under the 1940 Act was 209%, against a 150% legal floor; SBA-guaranteed debentures are excluded from that test under an SEC order. During the year the company refinanced $221.9 million of 2026 and 2028 notes with $350 million of 5.95% notes due 2030.
• Operating cash flow was negative $193.5 million. That is normal for a lender growing its book, because new loans count as an operating outflow. It does not measure whether earnings turn into cash the way it would for an industrial company.

Takeaway: Capital Southwest grew its loan book faster than its share count could keep up with at today's lower yields. NII per share fell to $2.37, below the $2.56 paid out, and NAV per share stayed flat only because new shares were sold above book value and a $1.07-per-share pool of undistributed income was available to draw on.

What to watch next

Management did not give numeric earnings guidance in the 10-K. The board declared another $0.58 regular dividend plus a $0.06 supplemental for the April–June 2026 quarter. Results since year end, from later filings, continue the same pattern. For the June 2026 quarter (the first quarter of fiscal 2027), pre-tax NII was $0.57 per share against $0.64 of dividends paid, NAV per share slipped to $16.61, and estimated undistributed taxable income fell from $1.07 to $0.87 per share. On October 15, 2026 the company estimated September-quarter NII at $0.56–$0.57 per share and NAV at $16.62–$16.67, with final results due November 2, 2026.

Our read: as long as quarterly NII stays near $0.57, the $0.58 regular dividend is roughly covered, but the $0.06 supplemental is being paid from the carried-forward income pool, which fell by $0.20 per share in the June quarter alone. Three things decide whether the supplemental lasts: whether benchmark rates keep falling, whether the rating-3 loans recover or slide to non-accrual, and whether the stock keeps trading far enough above NAV for share sales to keep adding to book value.
