Peabody Energy Corporation is facing a federal securities class action with an August 24, 2026 deadline for investors to seek appointment as lead plaintiff if they purchased or otherwise acquired the company's securities between October 14, 2024 and May 4, 2026, inclusive. The complaint alleges Peabody and certain executives misled investors about the condition of the Centurion mine and the issues delaying its ramp-up and return to full longwall production. The alleged inflation in the stock price began to unwind on March 30, 2026, when Peabody cut expected first-quarter output from roughly 700,000 tons to about 250,000 tons because of greater-than-anticipated mine commissioning challenges, sending the shares down $3.82, or about 9.7%, to $35.68. It fell further on May 5, 2026, after the company said Centurion had missed its March 2026 ramp-up target and reduced its full-year sales outlook for the mine to 2.5 million tons from 3.5 million tons, a disclosure that was followed by a $1.52, or 5.7%, drop to $25.00.
