 Exhibit 4.35 

FIRST SUPPLEMENTAL INDENTURE (this “First Supplemental Indenture”), dated as of August 26, 2021, among Indigo Natural
Resources LLC, a Delaware limited liability company (the “Company”), the Guarantors (as defined herein) and Wells Fargo Bank, National Association, as Trustee (the “Trustee”). 

The Company, the Guarantors and the Trustee have executed and delivered an Indenture, dated as of February 2, 2021 (as amended,
supplemented or otherwise modified from time to time, the “Indenture”) pursuant to which the Company issued 5.375% Senior Notes due 2029 (the “Notes”). 

Section 9.02 of the Indenture provides that the Company, the Guarantors and the Trustee may amend or supplement certain provisions of the
Indenture with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes voting as a single class (including consents obtained in connection with a tender offer or exchange offer for, or purchase of, the
Notes). 
 Southwestern Energy Company, a Delaware corporation (“Southwestern”), has offered to exchange (the
“Exchange Offer”) new 5.375% Senior Notes due 2029 issued by Southwestern for any and all outstanding Notes upon the terms and subject to the conditions set forth in the offering memorandum and consent solicitation statement dated
August 2, 2021 (the “Offering Memorandum”). 
 In connection with the Exchange Offer, Southwestern has also
solicited consents from the Holders of the Notes to certain proposed amendments (the “Proposed Amendments”) to the Indenture as described in the Offering Memorandum and set forth in this First Supplemental Indenture, with the
operation of such Proposed Amendments being subject to the satisfaction or waiver by Southwestern of the conditions to the Exchange Offer and the acceptance by Southwestern for exchange of the Notes validly tendered and not validly withdrawn
pursuant to the Exchange Offer. 
 Southwestern has received and caused to be delivered to the Trustee evidence of the consents from Holders
of a majority of aggregate principal amount of the Notes to effect the Proposed Amendments. 
 The Company is undertaking to execute and
deliver this First Supplemental Indenture to delete, amend or supplement, as applicable, certain provisions and covenants in the Indenture with respect to the Notes in connection with the Exchange Offer and the related consent solicitation and in
connection therewith, each of the Company and the Guarantors have duly authorized the execution and delivery of this First Supplemental Indenture. 

Each party hereto agrees as follows for the benefit of the other parties and for the equal and ratable benefit of the Holders of the Notes.
