Exhibit 99.1

ANTERO RESOURCES ANNOUNCES FINAL RESULTS OF TENDER OFFER FOR ITS 2021 NOTES

DENVER, COLORADO, August 17, 2020 /PRNewswire/ -- Antero Resources Corporation (NYSE: AR) (“Antero” or the “Company”) announced today that, as of 5:00 p.m., New York City time, on August 17, 2020, $191,566,000 principal amount of the Company’s outstanding 5.375% Senior Notes due 2021 (the “2021 Notes”) have been tendered and accepted for purchase (the “Tendered Notes”) pursuant to the previously announced cash tender offer (the “Any and All Offer”) on the terms and subject to the conditions set forth in the Offer to Purchase, dated as of August 11, 2020 (as it may be amended or supplemented from time to time, the “Offer to Purchase”). This amount includes $18,480,000 principal amount of 2021 Notes tendered pursuant to the guaranteed delivery procedures described in the Offer to Purchase and the related notice of guaranteed delivery provided in connection with the Any and All Offer, which remain subject to the holders’ performance of the delivery requirements under such procedures (the “Guaranteed Delivery Notes”).

Holders of 2021 Notes that have been accepted for purchase will receive the total consideration of $980.00 for each $1,000 principal amount of 2021 Notes purchased pursuant to the Any and All Offer, plus accrued and unpaid interest thereon from the last interest payment date to, but not including, August 18, 2020. Antero expects to make payment for the Tendered Notes (other than the Guaranteed Delivery Notes) on August 18, 2020 and to make payment for the Guaranteed Delivery Notes delivered pursuant to the guaranteed delivery procedures on August 20, 2020.

Based on the results of the Any and All Offer, the maximum purchase price, excluding accrued interest, available to purchase the Company’s outstanding 5.125% Senior Notes due 2022 and 5.625% Senior Notes due 2023 (collectively, the “Dutch Auction Notes” and, with the 2021 Notes, the “Notes”) subject to the previously announced cash tender offers (the “Dutch Auction Offers” and, collectively with the Any and All Offer, the “Offers”) will be $250,000,000, which was the maximum amount available for the Dutch Auction Offers regardless of the principal amount of Tendered Notes. The “Dutch Auction Cap” will be a principal amount of Dutch Auction Notes that can be purchased with such maximum purchase price.

The Dutch Auction Offers are scheduled to expire at 11:59 p.m., New York City time, on Tuesday, September 8, 2020, unless extended (the “Dutch Auction Expiration Date”). As more fully described in the Offer to Purchase, holders of Dutch Auction Notes who validly tender (and do not validly withdraw) their Dutch Auction Notes at or prior to 5:00 p.m., New York City time, on Monday, August 24, 2020, unless extended (the “Dutch Auction Early Tender Deadline”), will receive the applicable “Dutch Auction Total Consideration” (as defined in the Offer to Purchase), including a “Dutch Auction Early Tender Payment” of $30.00 per $1,000 principal amount of Dutch Auction Notes. Holders who validly tender their Dutch Auction Notes after the Dutch Auction Early Tender Deadline will not be eligible to receive the Dutch Auction Early Tender Payment.

Information relating to the Dutch Auction Notes and Dutch Auction Offers is set forth in the table below:

As previously announced, and as more fully described in the Offer to Purchase, the “Clearing Premium” will be determined pursuant to a modified “Dutch Auction” by consideration of the “bid price” specified by each holder that tenders Dutch Auction Notes prior to the Dutch Auction Early Tender Deadline. The bid premiums of Dutch Auction Notes validly tendered after the Dutch Auction Early Tender Deadline will not be used in determining the Clearing Premium. The Clearing Premium for the Dutch Auction Offers will be the lowest single bid premium (the amount by which bid price exceeds the “Base Price,” which is also equal to the minimum “bid price”) at which Antero will be able to purchase Dutch Auction Notes in an aggregate principal amount equal to the Dutch Auction Cap. If the aggregate amount of Dutch Auction Notes validly tendered (and not validly withdrawn) at or below the Clearing Premium would cause Antero to purchase more than the Dutch Auction Cap, then holders of Dutch Auction Notes tendered at the Clearing Premium will be subject to proration as described in the Offer to Purchase.
