Alpha Metallurgical Resources Inc (AMR) saw its stock plummet 10.37% in pre-market trading on Friday following the release of disappointing first-quarter results and reduced guidance for the fiscal year. The coal mining company reported a significant loss and missed analyst estimates, sparking concerns among investors about its financial health and future prospects.

The company reported a net loss of $2.60 per share for Q1 2025, a stark contrast to the net income of $9.59 per share in the same period last year. This result significantly missed the FactSet analyst estimate of a $0.59 loss per share. Revenue for the quarter also declined sharply to $532.0 million, down from $864.1 million a year earlier and falling short of the $573.2 million expected by analysts.

Adding to investor concerns, Alpha Metallurgical Resources reduced its Met Coal Sales guidance for the fiscal year to 13.8-14.8 million tons, indicating potential challenges in the coal market. The company also lowered its 2025 capital expenditure (Capex) guidance range to $130 million to $150 million, suggesting a more conservative approach to investments. These revisions, combined with the weak quarterly performance, have led to a pessimistic outlook for the stock, resulting in the significant pre-market decline.
