Sixth Street Specialty Lending, Inc. (TSLX) SEC Filings

Sixth Street Specialty Lending, Inc. reported second quarter 2026 net investment income and net income of $0.43 per share, producing annualized returns on equity of 10.6% and 10.5%, respectively. Reported net asset value per share was $16.24 at June 30, 2026, unchanged from March 31, 2026, as net investment income of $0.43 per share was largely offset by the second quarter base dividend of $0.42 per share and modest valuation movements. Total investment income was $97.8 million for the quarter versus $115.0 million a year earlier, primarily due to lower reference rates, while net expenses declined to $55.7 million from $62.9 million, helped by a lower average interest rate on debt outstanding.

The Board declared a third quarter 2026 base dividend of $0.42 per share to shareholders of record on September 15, 2026, payable September 30, 2026; there was no supplemental dividend related to Q2 earnings, though the supplemental framework remains in place. At June 30, 2026, the investment portfolio had an aggregate fair value of $3,302.1 million across 137 companies, with 88.3% in first-lien debt and only 1.3% of the portfolio at fair value on non-accrual status. The company held $193.6 million in cash and cash equivalents, total principal debt of $1,966.0 million, undrawn revolver capacity of $1,086.2 million, and a debt-to-equity ratio of 1.27x. It extended $1.525 billion of revolving credit facility commitments to May 1, 2031 and, after quarter-end, repaid $300 million of unsecured notes using revolver capacity and balance sheet cash.

After these changes, he reports 21,000 shares of common stock held directly and 23,907.27 shares held indirectly through Sixth Street Specialty Lending Advisers, LLC, reflecting both the new interest and shares previously reported as directly owned.

Sixth Street Specialty Lending, Inc. has issued $300,000,000 aggregate principal amount of 5.650% notes due 2031 under a Third Supplemental Indenture with U.S. Bank Trust Company, National Association, as trustee. The transaction closed on May 14, 2026.

The notes mature on August 15, 2031, are unsecured obligations, and pay interest at 5.650% per year, semiannually on February 15 and August 15, starting February 15, 2027. The company expects to use net proceeds mainly to pay down its revolving credit facility and for general corporate purposes, including new investments aligned with its investment strategy. If a defined change of control occurs and the notes are rated below investment grade, the company must offer to repurchase them at 100% of principal plus accrued interest.
