Alpha Metallurgical Resources Inc (AMR) experienced a significant pre-market decline of 6.94% following the release of its first-quarter 2026 financial results.

The company reported quarterly sales of $524.987 million, missing analyst consensus estimates of $538.533 million. It posted a net loss of $0.86 per share, which was significantly wider than the anticipated loss of $0.03 per share. Management attributed the revenue shortfall to lower shipping volumes caused by planned outages at the Dominion Terminal Associates export terminal.

Furthermore, the company stated that war-related increases in diesel and other supply prices had a greater-than-expected impact on first-quarter costs. While Alpha maintained its full-year cost guidance, it warned that if the Iran conflict persists, an upward revision to the cost of coal sales guidance may be required.
