Exhibit 99.1

UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS

On May 7, 2026, Devon Energy Corporation, a Delaware corporation (“Devon”), completed the previously announced transaction

with Coterra Energy Inc., a Delaware corporation (“Coterra”), pursuant to the Agreement and Plan of Merger, dated as of February 1, 2026 (the “Merger Agreement”), which provided for, among other things, the merger of

Cubs Merger Sub, Inc., a Delaware corporation and a then direct, wholly owned subsidiary of Devon, with and into Coterra, with Coterra surviving as a direct, wholly owned subsidiary of Devon (the “merger”). As a result of the

merger, each share of common stock of Coterra outstanding immediately prior to the effective time of the merger (other than certain excluded shares) was converted into the right to receive 0.70 shares of common stock of Devon and cash in lieu of

fractional shares, as applicable (the “merger consideration”). Additionally, as a result of the merger, each outstanding equity award of Coterra was treated in accordance with the terms of the Merger Agreement.

The following unaudited pro forma combined financial statements (the “Pro Forma Financial Statements”) have been prepared from the

respective historical consolidated financial statements of Devon and Coterra and give effect to the closing of the merger. The unaudited pro forma combined balance sheet (the “Pro Forma Balance Sheet”) is presented as if the merger had

been completed on March 31, 2026. The unaudited pro forma combined statement of operations (the “Pro Forma Statements of Operations”) for the three months ended March 31, 2026 and the year ended December 31, 2025 is

presented as if the merger had been completed on January 1, 2025.

The Pro Forma Financial Statements have been developed from and

should be read in conjunction with:

•

the unaudited consolidated financial statements of Devon and related notes thereto included in its Quarterly

Report on Form 10-Q for the three months ended March 31, 2026;

•

the audited consolidated financial statements of Devon and related notes thereto included in its Annual Report on

Form 10-K for the year ended December 31, 2025;

•

the unaudited condensed consolidated financial statements of Coterra and related notes thereto included in its

Quarterly Report on Form 10-Q for the three months ended March 31, 2026; and

•

the audited consolidated financial statements of Coterra and related notes thereto included in its Annual Report

on Form 10-K for the year ended December 31, 2025.

The Pro Forma Financial

Statements have been prepared to reflect adjustments to Devon’s historical consolidated financial information that are (i) directly attributable to the merger, (ii) factually supportable and (iii) with respect to the Pro Forma

Statement of Operations, expected to have a continuing impact on Devon’s results. Accordingly, the Pro Forma Financial Statements reflect the following:

•

the merger, using the acquisition method of accounting for business combinations, with Devon as the accounting

acquirer and each share of Coterra common stock converted into 0.70 shares of Devon common stock;

•

the assumption of liabilities for expenses directly attributable to the merger; and

•

the conforming of Coterra’s historical amounts to Devon’s financial statement presentation and

accounting policies, including reclassifications of certain line items for consistent presentation.

Under the

acquisition method of accounting for business combinations, the merger consideration is allocated to the assets acquired and liabilities assumed by Devon in connection with the merger based on their estimated fair values. As of the date of this

report, Devon has not completed the detailed valuation study necessary to arrive at the required final estimates of the fair value of the acquired Coterra assets and assumed liabilities. As soon as practicable, Devon will identify the Coterra assets

acquired and liabilities assumed and make final determinations of their fair values using relevant information available at that time. As a result of the foregoing, the pro forma adjustments with respect to the merger are preliminary and are subject

to change as additional information becomes available and as additional analysis is performed. The fair value of assets acquired and liabilities assumed upon completion of the final valuations may differ materially from the preliminary estimates

presented in the Pro Forma Financial Statements.

Although helpful in illustrating the financial characteristics of the combined company

under one set of assumptions, the Pro Forma Financial Statements do not reflect the benefits of expected cost savings (or associated costs to achieve such savings), opportunities to earn additional revenue or other factors that may result after the

merger and, accordingly, do not attempt to predict or suggest future results. Specifically, the Pro Forma Statements of Operations exclude projected synergies expected to be achieved as a result of the merger, as well as any associated costs that

may be required to achieve such projected synergies. Further, the Pro Forma Financial Statements do not reflect the effect of any regulatory actions that may impact the results of the combined company following the merger.

NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS

Basis of Presentation

The Devon and

Coterra historical financial information have been derived from each respective company’s Quarterly Report on Form 10-Q for the three months ended March 31, 2026 and Annual Report on Form 10-K for the year ended December 31, 2025. Certain of Coterra’s historical amounts have been reclassified to conform to Devon’s financial statement presentation. These Pro Forma Financial Statements

should be read in conjunction with the historical financial statements and related notes thereto of Devon and Coterra.

The Pro Forma

Balance Sheet is presented as if the merger had been completed on March 31, 2026. The Pro Forma Statements of Operations for the three months ended March 31, 2026 and for the year ended December 31, 2025 are presented as if the merger

had been completed on January 1, 2025.

The Pro Forma Financial Statements reflect pro forma adjustments that are described in the

accompanying notes and are based on currently available information. Preliminary adjustments have been made that are necessary to present fairly the Pro Forma Financial Statements and are subject to change as additional information becomes available

and as additional analysis is performed. The Pro Forma Financial Statements do not purport to represent what the combined company’s financial position or results of operations would have been if the merger had actually occurred on the dates

indicated, nor are they indicative of Devon’s future financial position or results of operations. Actual results may differ materially from the assumptions and estimates reflected in these Pro Forma Financial Statements.

Merger Consideration and Purchase Price Allocation

The transaction is accounted for using the acquisition method of accounting for business combinations, with Devon as the accounting acquirer.

The allocation of the preliminary estimated purchase price with respect to the merger is based upon Devon’s estimates of, and assumptions related to, the fair value of assets to be acquired and liabilities to be assumed as of March 31,

2026 using currently available information. Because the unaudited pro forma combined financial statements have been prepared based on these preliminary estimates, the final purchase price allocation and the resulting effect on financial position and

results of operations of the combined company may be materially different from the pro forma amounts included herein. Devon expects to finalize the purchase price allocation as soon as practicable.

The preliminary purchase price allocation is subject to change due to several factors, including, but not limited to:

•

changes in the estimated fair value of Coterra’s identifiable assets acquired and liabilities assumed as of

the closing date of the merger, which could result from changes in oil and natural gas commodity prices, reserve estimates, discount rates and other factors;

•

the tax bases of Coterra’s assets and liabilities as of the closing date of the merger; and

•

the factors described in the section entitled “Risk Factors” beginning on page 25 of Devon’s

and Coterra’s joint proxy statement/prospectus related to the merger.

The preliminary value of the merger consideration and its allocation to the net assets

acquired is as follows (in millions, except exchange ratio data):
