Peabody Energy faces fraud suit after 37% stock decline on mine woes

Peabody Energy lost 37% of its market value after revealing production failures at its Centurion mine, sparking a securities fraud lawsuit from shareholders.

"Peabody's repeated assurances that Centurion was 'on time and on budget' and 'ahead of schedule' were materially false and misleading," Peretz Bronstein, founding partner at Bronstein Gewirtz & Grossman, said in a statement announcing the firm's involvement.

The lawsuit, filed in the U.S. District Court for the Eastern District of Missouri, covers investors who bought Peabody common stock between Oct. 14, 2024 and May 4, 2026. Peabody had said shipments from Centurion, its flagship premium hard coking coal mine in Queensland, Australia, would expand sevenfold in 2026 to 3.5 million tons. On Feb. 5, 2026, the company said the team was "putting the finishing touches on the Centurion mine in advance of starting longwall mining, well ahead of its original schedule."

In truth, the mine faced unanticipated electrical and mechanical problems, roof control deterioration and floor softening that made the March 2026 longwall production deadline unachievable, according to the complaint. On March 30, Peabody disclosed first-quarter sales volume of just 250,000 tons — far below the roughly 700,000 tons analysts expected — citing "greater than anticipated mine commissioning challenges." The stock fell $3.82, or 9.7%, to $35.68 that day.

On May 5, Peabody cut its full-year Centurion sales outlook to 2.5 million tons from 3.5 million tons and raised cost guidance to $123 to $133 per ton. The company said it expected only about 300,000 tons in the second quarter. Shares dropped another $1.52, or 5.7%, to $25.00, bringing the cumulative decline from the pre-disclosure high of $39.50 to roughly 37%. The first-quarter shortfall alone carried an $80 million EBITDA impact, the company said.

The complaint asserts claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934. Investors have until Aug. 24, 2026 to petition the court to serve as lead plaintiff. Multiple law firms — including Bleichmar Fonti & Auld, Bernstein Liebhard, Rosen Law Firm and Hagens Berman — have announced investigations or filed actions on behalf of shareholders.

The lawsuit puts Peabody's flagship growth project under a legal microscope at a time when the coal producer is already grappling with operational setbacks at its most valuable asset. The Aug. 24 lead plaintiff deadline will determine which firm directs the litigation and how the case proceeds.
