Credit Snapshot
How the market and the balance sheet read TSLX as a credit: NAV per share is the Q2 FY2026 book value ($16.30) from its SEC quarterly filing — for a BDC, book value is NAV. Fair values underneath are the manager’s own estimates. Price as of 2026-08-26.
| Metric | Value | What healthy looks like |
|---|---|---|
| Price-to-NAV | 1.16x (premium) | Quality BDCs tend to trade near NAV; a deep discount often signals credit concern — or opportunity to investigate. |
| Dividend Yield (FY2025 paid) | 9.5% | A trailing all-in yield (full-year dividends paid, including any specials) — not a forward run-rate. BDC regular yields typically run 8–12%; treat an outlier as a question about dividend sustainability. |
| Dividend Coverage (GAAP NII) | 1.26x GAAP NII ÷ FY2025 distributions | Above 1.0x, the year’s distributions were earned by investment income; below 1.0x they exceeded it — watch for a cut or return-of-capital funding. GAAP NII, not the manager’s adjusted “core NII”. |
| NII Return on Equity | 13.4% GAAP NII on FY2025 FY-end NAV | What the portfolio EARNED on book value, before mark swings — steadier than mark-driven ROE. BDCs typically land high single digits to low teens; internally managed books keep more of it. |
| NAV Total Return | +8.2% FY2025: ΔNAV/share + distributions 3-yr ≈+10.4%/yr compound | NAV change plus distributions, per share — what the book earned independent of market sentiment. Sustained positive NAV total return means the credit book is creating value, not just distributing it back. |
| Leverage (Gross Debt/Equity) | 1.08x target 0.90–1.25x (manager-stated) — within 46% headroom to the 2.0x regulatory ceiling | Most BDCs run 0.8x–1.25x debt-to-equity; the regulatory ceiling is 2.0x. |
| Asset Coverage | 192% | A gross total-debt coverage read; the statutory ratio excludes SBA debentures, so an SBIC’s 10-K figure can differ. Healthy BDCs sit well above the 150% floor. |
| Top-5 Borrower Concentration | 18% of portfolio FV ≈ 38% of Q2 FY2026 NAV largest: Hippo XPA Bidco AB (8.9% of FV) | Measured against NAV, not just portfolio value: leverage means one borrower’s writedown hits book value harder than its portfolio share suggests. Diversified BDCs typically keep any single name to a low single-digit share of the portfolio. |
| PIK Income Share | 19.0% of debt FV carries a PIK component 74th pct of 23 upper-MM peers | Interest paid “in kind” adds to the loan instead of paying cash; a rising PIK share is the classic early sign of borrower stress. |
| Floating-Rate Mix | 77% floating, mostly SOFR of rate-classified debt (91% coverage); the rest fixed | Floating-rate loans reprice with their benchmark (mostly SOFR), so a high floating share means portfolio income rises when the Fed hikes and falls when it cuts — the book’s rate sensitivity in one number. |
| Non-Accruals | — not yet parsed | 1–3% of debt fair value is normal; 5%+ is a warning sign. We don’t parse this yet — check the latest 10-Q. |
| Fee Structure — manager economics, from the same annual filing | ||
| Base Management Fee | $52.2M ≈1.52% of FY2025 FY-end total assets, our calculation — contractual fees accrue on average gross assets as filed, gross of any fee waivers | External BDC base fees typically run 1.0–1.75% of assets — charged on ASSETS, not equity, so leverage raises the fee bill on the same NAV. |
| Incentive Fee | $43.5M ≈16.8% of pre-fee investment income as filed, gross of any fee waivers | Income incentive fees typically take 17.5–20% of pre-fee investment income over a hurdle. A capital-gains fee in an up-mark year is not recurring income economics — watch the split. |

Maturity Wall
Debt fair value by each loan’s stated maturity year (93% of debt FV carries a parsed maturity). The refinancing question: 12% of the maturity-dated book comes due by end-2027 — debt that must be repaid, refinanced, or extended. As of the 2026-08-04 filing.
| Maturing | Debt FV | % of dated debt |
|---|---|---|
| 2026 or earlier | $50M | 1.6% |
| 2027 | $314M | 10.4% |
| 2028 | $529M | 17.4% |
| 2029 | $374M | 12.3% |
| 2030 | $566M | 18.7% |

Quarter-over-quarter changes
Borrowers added to and dropped from the book between the 2026-05-05 and 2026-08-04 filings, and the largest weighted-mark moves on borrowers held across both. Aggregated to the borrower so a company’s exposure is counted once even when its loan tranches are re-cut quarter to quarter; entries and exits under $0.5M are omitted as parse noise.

Marks reflect each BDC’s own fair-value estimates as reported to the SEC, not traded prices. Private-credit loans are predominantly Level 3 under ASC 820 — valued from unobservable inputs and determined in good faith by each BDC’s board, so figures are estimates as of the filing date and are not directly comparable across managers. Informational only; not investment advice or a valuation.

About Sixth Street Specialty Lending
Sixth Street Specialty Lending (TSLX) is a publicly traded Business Development Company (BDC) — essentially a publicly listed fund that lends money to mid-sized private companies. In plain English: BDCs raise money from public investors and lend it to businesses that are too small for Wall Street banks. To qualify for pass-through tax treatment, they distribute at least 90% of their taxable investment income to shareholders, which is why BDC yields are often 8–12%. Sixth Street Specialty Lending discloses its full loan portfolio through SEC filings.
