ANTERO RESOURCES COMMENCES TENDER OFFERS FOR ITS 2021, 2022 AND 2023 NOTES

DENVER, COLORADO, August 11, 2020 /PRNewswire/ -- ANTERO RESOURCES CORPORATION (NYSE: AR) (“Antero” or the “Company”) announced today that it has commenced cash tender offers (the “Offers”) to purchase (i) any and all of the Company’s outstanding 5.375% Senior Notes due 2021 (such notes, the “Any and All Notes” and, such offer, the “Any and All Offer”) and (ii) up to the Dutch Auction Cap (as defined below) of the Company’s outstanding 5.125% Senior Notes due 2022 the (“2022 Notes”) and the Company’s 5.625% Senior Notes due 2023 (the “2023 Notes” and, together with the 2022 Notes, the “Dutch Auction Notes” and, such offers, the “Dutch Auction Offers” and, the Dutch Auction Notes together with the Any and All Notes, the “Notes”), in each case, on the terms and subject to the conditions set forth in the Offer to Purchase, dated the date hereof (as it may be amended or supplemented from time to time, the “Offer to Purchase”). The Dutch Auction Cap will be a principal amount of 2022 Notes and/or 2023 Notes that could be purchased with a maximum purchase price, excluding accrued interest, equal to $525,000,000 less the aggregate amount paid by the Company to purchase the Any and All Notes (other than accrued interest) in the Any and All Offer, but in no event more than $250,000,000 (such amount, the “Dutch Auction Cap”). The Any and All Offer is scheduled to expire at 5:00 p.m., New York City time, on Monday, August 17, 2020, unless extended (such time and date, as the same may be extended, the “Any and All Expiration Date”). The Dutch Auction Offers are scheduled to expire at 11:59 p.m., New York City time, on Tuesday, September 8, 2020, unless extended (such time and date, as the same may be extended, the “Dutch Auction Expiration Date”). Information relating to the Notes and the Offers is set forth in the table below.

Holders of Any and All Notes who validly tender (and do not validly withdraw) their Any and All Notes at or prior to 5:00 p.m., New York City time on Monday, August 17, 2020, unless extended, or who comply with the guaranteed delivery procedures in accordance with the instructions described in the Offer to Purchase, will receive total consideration of $980.00 per $1,000 principal amount of Any and All Notes purchased pursuant to the Offers. There will not be an early tender payment for the Any and All Notes.

The total consideration payable for each $1,000 principal amount of Dutch Auction Notes will be determined based on a modified “Dutch Auction” procedure. 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,” 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.

As more fully described in the Offer to Purchase, the Dutch Auction Total Consideration for each $1,000 principal amount of the Dutch Auction Notes validly tendered (and not validly withdrawn) at or prior to the Dutch Auction Early Tender Deadline and accepted for purchase will be equal to the sum of: (1) the “Base Price” for the Dutch Auction Notes, which is also equal to the minimum “bid price,” and (2) the “Clearing Premium,” which 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 pursuant to the Offers. 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 bid price for tendered Dutch Auction Notes represents the minimum consideration a holder is willing to receive for those Dutch Auction Notes and must fall within the acceptable bid price range specified in the table above and be in increments of $5.00.

The total consideration for each $1,000 principal amount of the Dutch Auction Notes validly tendered (and not validly withdrawn) after the Dutch Auction Early Tender Deadline and at or prior to the Dutch Auction Expiration Date and accepted for purchase will consist of the Dutch Auction Total Consideration less the Dutch Auction Early Tender Payment (the “Dutch Auction Offer Consideration”).

As more fully described in the Offer to Purchase, 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) at which the Company 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 the Company to purchase more than the Dutch Auction Cap for the Dutch Auction Offers, then holders of Dutch Auction Notes tendered at the Clearing Premium will be subject to proration as described in the Offer to Purchase.

In addition, the Company will pay accrued and unpaid interest on all Notes tendered and accepted for payment in the Offers from the last interest payment date to, but not including, the applicable settlement date.

Tendered Any and All Notes may be validly withdrawn at any time by the Any and All Expiration Date, but not thereafter unless otherwise required by applicable law. Tendered Dutch Auction Notes may be validly withdrawn at any time prior to 5:00 p.m., New York City time, on Monday, August 24, 2020, unless extended (the “Dutch Auction Withdrawal Deadline”), but not thereafter unless otherwise required by applicable law.

The Company reserves the right, in its sole discretion, to increase the Dutch Auction Cap for the Dutch Auction Notes. If the Company increases the Dutch Action Cap, it does not currently intend to extend the Dutch Auction Withdrawal Deadline or otherwise reinstate withdrawal rights, subject to applicable law.

Consummation of the Offers is subject to the satisfaction or waiver of certain conditions, which are more fully described in the Offer to Purchase. If any of the conditions are not satisfied, the Company may terminate the Offers and return tendered Notes. The Company has the right to waive any conditions with respect to the Notes and to consummate the Offers. In addition, the Company has the right, in its sole discretion, to terminate the Offers at any time, subject to applicable law. The Company has the right, in its sole discretion, to amend, extend or terminate an Offer without amending, extending or terminating any other Offer.
