A major global law firm has announced the formal filing of a securities class action lawsuit against coal producer Peabody Energy Corp (BTU). Investors who purchased the company's common stock between October 14, 2024, and May 4, 2026, can apply to serve as lead plaintiff by August 24, 2026.

The legal action stems from significant commissioning delays at Peabody Energy's flagship asset, the Centurion metallurgical coal mine in Queensland, Australia. The complaint alleges that the company and certain executives made false and misleading statements regarding the mine's production ramp-up, creating a false impression for investors that the company had reliable information about its capacity while multiple underlying issues were causing delays.

On March 30, 2026, Peabody Energy issued a press release reducing its first-quarter 2026 production forecast for the Centurion mine by approximately 450,000 tonnes, citing greater-than-expected commissioning challenges. The company's share price fell 9.7% on that day, closing at $35.68.

On May 5, 2026, the company further disclosed that it had failed to meet its previously stated target of full production by March 2026, and it cut its full-year metallurgical coal sales guidance from 3.5 million tonnes to 2.5 million tonnes. This news caused the stock price to drop another 5.7% to $25.00. From March 27 to May 5, the stock declined by approximately 36%.

According to its first-quarter 2026 financial report, the company posted a net loss of $32.4 million. Its adjusted EBITDA was $82.5 million, a 43% year-over-year decline. Its Seaborne metallurgical coal business segment recorded a loss of $7 million.
