Sixth Street Specialty Lending, Inc. (NYSE: TSLX) reported third-quarter 2026 net investment income of $41.6 million, or $0.44 per share, as investment activity picked up and the portfolio expanded to $3.39 billion at fair value. Net investment income increased from $0.43 per share in the prior quarter but remained below $0.54 a year earlier. The company declared a $0.42-per-share base dividend and a $0.01 supplemental dividend related to the quarter.

Net income was $34.4 million, or $0.36 per share, compared with $40.5 million, or $0.43 per share, in the second quarter and $44.6 million, or $0.47 per share, a year earlier. The latest result included $7.2 million of net unrealized and realized losses.

Total investment income reached $99.0 million, up from $97.8 million in the previous quarter but down from $109.4 million in the year-earlier period. Interest and dividend income was $89.7 million, while other investment-related fees contributed $6.7 million. Net expenses were $56.2 million, including $30.5 million of interest expense, $13.3 million of management fees and $8.8 million of incentive fees on net investment income.

Annualized return on equity based on net investment income was 10.7%, compared with 10.6% in the second quarter. Annualized net income return on equity was 8.9%, down from 10.5% sequentially.

Portfolio expands as funding activity increases

TSLX made $242 million of investment commitments and funded $247 million during the quarter. Fundings covered four new investments, five increases to existing positions and capital called by Structured Credit Partners. Paydowns and sales totaled $160 million, resulting in net funded investment activity of $87 million, reversing the prior quarter’s $55 million net outflow.

Investments at fair value rose to $3.39 billion from $3.30 billion at June 30. Excluding structured-credit investments, the portfolio contained 103 companies, with an average position of $32.2 million. The largest individual investment represented 2.4% of total investments, while the 10 largest borrowers accounted for about 21% of the portfolio.

The portfolio remained concentrated in senior, floating-rate credit. First-lien debt represented 87% of investments, and 97.6% of income-producing debt investments carried floating rates. The weighted-average total yield on debt and other income-producing securities was 11.4% at both amortized cost and fair value. The weighted-average spread over reference rates on floating-rate investments narrowed to 6.9% from 7.0% in the prior quarter.

New commitments carried a weighted-average interest rate of 10.2% and a weighted-average spread of 6.0% over reference rates. The fair value of debt investments equaled 97.3% of principal, compared with 97.5% at the end of the second quarter. Investments on non-accrual status represented 1.1% of the portfolio at fair value.

NAV edges lower; leverage returns to target ceiling

Net asset value was $16.19 per share at September 30, down from $16.24 three months earlier. Adjusted NAV, reflecting the quarter’s supplemental dividend, was $16.18 per share. Net investment income of $0.44 per share and $0.07 per share from the reversal of unrealized gains associated with paydowns and sales were offset by the $0.42 base dividend, $0.10 of spread-related net unrealized losses, $0.02 of net realized losses and other changes.

Quarter-end debt-to-equity was 1.25 times, down from 1.27 times in June and at the upper end of TSLX’s stated target range of 0.90 to 1.25 times. Outstanding debt principal totaled $1.94 billion, while net assets were $1.55 billion.

The company reported approximately $817 million of liquidity, consisting primarily of undrawn revolving-credit capacity and unrestricted cash. That compared with $219 million of unfunded commitments available under underlying loan agreements. TSLX said available liquidity was 3.7 times those commitments, although revolver availability remains subject to borrowing-base, letter-of-credit and asset-coverage limitations.

TSLX’s debt had a weighted-average remaining maturity of about four years, compared with an estimated 2.4-year remaining life for investments funded with debt. Unsecured funding represented 64% of the company’s debt mix. During the quarter, TSLX repaid $300 million of unsecured notes that matured in August 2026.

Management’s presentation emphasized continued investment at the top of borrowers’ capital structures, direct origination and active portfolio management. It did not provide formal earnings or portfolio-growth guidance.
