The lawsuit, filed in the U.S. District Court for the Eastern District of Missouri, alleges that Peabody Energy and its executives violated the Securities Exchange Act of 1934. According to the complaint, the company provided false assurances about the Centurion mine's production growth while failing to disclose significant operational delays that hindered the return to full longwall output.

Financial impacts emerged in early 2026 as these issues surfaced. On March 30, the company lowered its first-quarter output guidance for the Centurion mine by 450,000 tons, triggering a nearly 10% drop in stock price. A further decline of approximately 6% followed on May 5, when the firm confirmed it had missed the March deadline for the ramp-up and reduced its full-year volume projections. Robbins Geller Rudman & Dowd LLP, the firm representing the plaintiffs, is inviting investors with substantial losses to participate in the case.
