Alpha Metallurgical Resources, Inc.

Notes:

1. Based on committed and priced coal shipments as of July 30, 2026. Committed percentage based on the midpoint of shipment guidance range.

2. Actual average per-ton realizations on committed and priced tons recognized in future periods may vary based on actual freight expense in future periods relative to assumed freight expense embedded in projected average per-ton realizations.

3. Includes estimates of future coal shipments based upon contract terms and anticipated delivery schedules. Actual coal shipments may vary from these estimates.

4. Note: The Company is unable to present a quantitative reconciliation of its forward-looking non-GAAP cost of coal sales per ton sold financial measures to the most directly comparable GAAP measures without unreasonable efforts due to the inherent difficulty in forecasting and quantifying with reasonable accuracy significant items required for the reconciliation. The most directly comparable GAAP measure, GAAP cost of sales, is not accessible without unreasonable efforts on a forward-looking basis. The reconciling items include freight and handling costs, which are a component of GAAP cost of sales. Management is unable to predict without unreasonable efforts freight and handling costs due to uncertainty as to the end market and FOB point for uncommitted sales volumes and the final shipping point for export shipments. These amounts have varied historically and may continue to vary significantly from quarter to quarter and material changes to these items could have a significant effect on our future GAAP results.

5. Excludes expenses related to non-cash stock compensation and non-recurring expenses.

6. Includes contributions to fund normal operations at our DTA export facility and expected capital investments related to the facility upgrades.
