FS KKR Capital Corp, once considered a benchmark in the industry and backed by private equity giant KKR, has now been labeled as junk-rated. Moody’s reasoning is direct and striking: the fund’s non-performing loan ratio in the software sector has surged to 5.5%, the highest among rated business development companies (BDCs). By comparison, its non-performing ratio was around 2% — considered healthy — at the end of 2024. In just one year, the figure has more than doubled, revealing a rapidly deteriorating portfolio.

Even more concerning are the structural risks. Moody’s noted that FS KKR’s leverage is higher than its peers, its exposure to payment-in-kind (PIK) loans is elevated, and its share of first-lien loans is lower than comparable funds. In simple terms: the fund has borrowed more to invest, many of its borrowers are distressed companies unable to pay interest and forced to roll over debt, and in the event of default, the fund ranks lower in the repayment hierarchy. In a bull market, this might be described as “high risk, high return.” In the current environment, it looks more like a fragile balance.

Financial data reinforces this assessment. According to Moody’s, FS KKR recorded a net loss of $114 million in the fourth quarter of 2025, with full-year net profit of just $11 million. For a fund managing tens of billions of dollars, this effectively amounts to a year with minimal returns.

A Wave of Bad Debt in the Software Sector

FS KKR’s challenges are not an isolated case. Moody’s explicitly pointed to software sector exposure as the root cause. In recent years, private credit funds have poured capital into software companies, attracted by narratives of high growth, recurring subscription revenue, and the appeal of the tech sector. However, as interest rates have risen and financing costs have surged, many software companies reliant on cash burn to sustain growth are now under severe pressure.

The broader private credit sector is also showing signs of stress. Apollo Global Management has reportedly faced large redemption requests this week, while JPMorgan CEO Jamie Dimon has ordered a comprehensive review of the bank’s loan book to assess exposure to software companies. Lending limits have already been tightened for some private credit funds with significant exposure to the sector. The market has even coined a term for the unfolding crisis: “Saaspocalypse.”

This is far from alarmist. According to Preqin, the global private credit market has expanded to nearly $2 trillion. How much of that capital has been allocated to software companies? How many of those firms have cash flows insufficient to cover interest payments? These questions were largely ignored during the boom, but with Moody’s downgrade acting as a trigger, the market is now being forced to confront the answers.

The broader impact may be psychological. For years, private credit has been marketed as a “perfect asset class” — safer than equities, yet offering higher yields than traditional bonds. But if even a top-tier player like KKR has stumbled, the outlook for smaller funds becomes far more uncertain.

Fitch Ratings had already warned in February that the private credit market suffers from “limited transparency” and “lagging asset valuations,” which may obscure the true level of risk. Now, Moody’s downgrade has effectively lifted the veil, exposing the underlying vulnerabilities of the sector.

In short, what once appeared to be a stable and high-yielding alternative investment is increasingly revealing itself as a system vulnerable to macro shocks, rising defaults, and structural imbalances.
