KKR’s FSK Fund: A Key Fault Line in Private Credit

A group of banks led by JPMorgan Chase & Co. Has reduced the credit facility for FS KKR Capital Corp., a private credit fund co-managed by KKR and Future Standard, as the vehicle faces mounting losses and portfolio stress.

On May 8, 2026, the JPMorgan-led lender group cut the fund’s credit line by approximately $648 million, a reduction of about 14%, bringing the facility down to $4.05 billion. Along with the reduction in available credit, the lenders increased borrowing costs for the fund. According to the filing, some lenders may have chosen to exit their positions entirely rather than extend their existing commitments.

Days after the credit line amendment, FS KKR Capital announced a $300 million support package provided by KKR to stabilize the business development company. These measures, which the fund described as Strategic Value Enhancement Actions, consist of a $150 million equity injection from KKR and an additional $150 million allocated to purchase shares from investors seeking to exit the fund.

Financial Losses and Credit Downgrades

The liquidity measures follow a period of significant financial deterioration for the fund, known by its ticker FSK. The fund reported losses of approximately $560 million for the first quarter of 2026. During this period, nonaccrual loans within the portfolio climbed to 8.1%.

The fund’s market performance has mirrored its internal losses, with shares plunging by nearly half over the past year. FSK shares currently trade at a deep discount to the fund’s net asset value.

In March 2026, Moody’s downgraded the ratings of FS KKR Capital to junk status, citing mounting stress within the fund’s portfolio. Fund executives confirmed on May 11, 2026, that loans to dental services firm Affordable Care and software maker Medallia have stopped paying interest.

Class Action Litigation Over Disclosures

The fund is also facing legal challenges regarding how it communicated its financial health to shareholders. On May 5, 2026, a proposed class action lawsuit was filed in the U.S. District Court for the Eastern District of Pennsylvania.

The lawsuit, filed by lead plaintiff Calvin Stuart on behalf of investors who purchased FSK shares between May 8, 2024, and February 25, 2026, names FS KKR Capital Corp. As well as Chief Financial Officer Steven Lilly and Chief Executive and Chairman Michael C. Forman. The suit alleges that the company downplayed the prevalence of bad loans while promoting portfolio stability and the prospect of rich dividends.

The filing claims that for five consecutive quarters through the first quarter of 2025, the company described a credit profile that was steadily improving and asserted that legacy non-accrual issues were being resolved through restructuring. The lawsuit alleges that SEC filings and press releases repeatedly emphasized portfolio stability and attractive distributions.

According to the complaint, this narrative began to collapse on August 6, 2025, when FS KKR reported that the fair value of investments had fallen by $474 million. The company also reported that net asset value per share dropped 6.2% to $21.93 in the second quarter of 2025. At that time, non-accruals rose to 5.3% at amortized cost, and 3.0% at fair value.

Management attributed those losses to company-specific issues at four portfolio companies: Worldwise, Kellermeyer Bergensons Services, 48forty, and Production Resource Group. The lawsuit notes that some of these companies had already undergone restructuring processes prior to the report. Following the August 6, 2025, disclosure, FSK shares declined by 8.20% the following day.
