The lawsuit, Stuart v. FS KKR Capital Corp., alleges that the company and its executives violated the Securities Exchange Act of 1934 by misrepresenting the effectiveness of portfolio restructuring and valuation processes. According to the filing, these omissions masked underlying issues within the firm's debt securities portfolio.

Financial disclosures from August 2025 and February 2026 revealed a pattern of decline, with net asset values dropping and non-accrual investments rising. Following the February announcement—which included a dividend cut and acknowledgments of performance challenges regarding assets like Medallia and Cubic Corp.—the company's stock price fell by more than 15%. Investors interested in serving as lead plaintiff must file motions with the court by July 6, 2026. Robbins Geller Rudman & Dowd LLP is representing the case.
