Antero Resources — Apr 29, 2026 release

This results in a full year average of approximately 4.1 Bcfe/d, unchanged from prior guidance. This annual guidance reflects approximately 20% growth year-over-year. The Company is increasing its ethane realized price premium to Mont Belvieu to $2.00 to $3.00 per barrel, reflecting a $1.00 per barrel increase at the midpoint from the prior guidance range. The Company is reducing its cash production expense guidance to a range of $2.25 to $2.35 per Mcfe, a $0.10 per Mcfe reduction at the midpoint. The lower cash production expense is due primarily to the impact of the integration of the lower production costs associated with the HG assets.       2026 Initial     2026 Revised   Full Year 2026 Guidance Updates   Low     High     Low     High   Ethane Realized Price Premium vs. Mont Belvieu ($/Bbl)   $ 1.00     $ 2.00     $ 2.00     $ 3.00   Cash Production Expense ($/Mcfe) (1)   $ 2.35     $ 2.45     $ 2.25     $ 2.35     (1) Includes lease operating, gathering, compression, processing and transportation expenses (“GP&T”) and production and ad valorem taxes.   Note: Any 2026 guidance items not discussed in this release are unchanged from previously stated guidance.   Natural Gas Hedge Program   The following tables detail Antero’s swap and collar hedge position as of the publication of April 24, 2026.
