Antero Resources Corporation revised production guidance for the year 2021. The company increased guidance for its realized natural gas price to a premium to NYMEX of $0.20 to $0.30 per Mcf from a previous range of $0.15 to $0.25 per Mcf, reflecting a 25% increase at the midpoint. The increase was driven by a greater BTU uplift on the Company's natural gas sales as well as tighter differentials in the NYMEX-related markets where Antero's gas is sold.
