- • The KMDM rate by count rose to approximately 3.6%, with a record 112 borrowers and the largest quarterly gain, though still below the early-2025 peak of 3.9%.
- • Roughly 20% of borrowers reported negative revenue CAGR, the highest share in the series and about twice the level at the start of 2024, while median leverage rose to 6.2x, its first increase in more than two years.
- • Surveillance downgrades reached a record 121, lifting the downgrade rate to 15% from 11% QoQ, and the share of new assessments rated ccc+ or lower hit a record 31%.

Summary
Kroll Bond Rating Agency (KBRA) released its Q3 2026 Middle Market Borrower Surveillance Compendium, which examines 3,070 middle market borrowers representing more than $1.4 trillion of direct lending debt assessed during the last twelve months ended September 30, 2026. KBRA's middle market assessment population surpassed 3,000 unique sponsored global obligors for the first time in the LTM period. According to the report, median portfolio fundamentals remain relatively stable, but credit performance is increasingly diverging, with weaker borrowers masking deterioration beneath the medians.
Lower-MM borrowers, which appear increasingly vulnerable to operating, liquidity and leverage pressures, recorded KMDM rates by count and by debt of 5.8%, compared with 3.6% and 2.4% for the entire portfolio. Stress is particularly visible in two of the largest direct lending sectors, Commercial and Professional Services and Health Care Services and Technology, where KMDM rates by count have risen above 4%. The KMDM rate by count for the portfolio reached approximately 3.6% after a record 112 borrowers were added, the largest quarterly gain, though this remains below the early-2025 peak of 3.9%. Of the 35 additions in Q3, the two sectors accounted for 16, with LTM KMDM by count rates of 4.6% and 4.4%, respectively.
Operating trends reinforce these signals. KBRA reported that roughly 20% of borrowers posted a negative revenue CAGR, the highest share in the series and roughly twice the level at the start of 2024, and more than half of those with falling revenue also reported lower EBITDA. Median revenue CAGR held at 12% quarter-over-quarter, while median EBITDA CAGR slowed to 23%. Median leverage rose to 6.2x, its first increase in more than two years, and median interest coverage held at 1.6x. KBRA believes a modest rate increase would have a limited impact on most borrowers, although highly leveraged credits with limited liquidity remain vulnerable.
Surveillance metrics also deteriorated. Downgrades reached a record 121 in the quarter, lifting the surveillance downgrade rate to 15% from 11% QoQ, though still well below its prior peak. The share of new assessments rated ccc+ or lower rose to a record 31% from 19% in Q2; KBRA noted these may partly reflect first reviews of seasoned loans, but said the trends suggest renewed credit pressure that could lift future KMDM rates. The report reviewed a record 787 surveillance assessments and 323 new assessments in Q3 2026.
Refinancing risk is building. Remaining 2026 maturities declined modestly to 115 companies (4% of assessed companies) with $26.9 billion due (2% of total debt). In 2027, maturities rise to 350 companies (12%) with $107 billion due (7% of total debt). Health Care Services and Technology carries the largest maturity wall, about $36 billion due in 2027, of which $8 billion is owed by companies rated ccc+ or ccc, the largest such exposure across sectors. KBRA warned that this combination of refinancing needs and weak credit quality could trigger additional sector defaults.
