CEO COMMENTARY

“Devon delivered another strong quarter in the first quarter of 2026, beating guidance across major value drivers, including oil production and

capital,” said Clay Gaspar, president and CEO. “Our relentless focus on operational excellence and cost discipline continues to drive significant free cash flow and meaningful returns to shareholders. We are also on track to achieve a

significant milestone with the full delivery of our $1 billion business optimization target well ahead of schedule, further strengthening our future margins and positioning Devon for long-term success as we head into the close of our

transformative merger with Coterra.”

“With the overwhelming support of both companies’ shareholders, we have cleared a major milestone

and are excited to move toward closing this transformative merger with Coterra Energy,” Gaspar added. “As we bring these two organizations together, we are confident in our ability to unlock significant synergies, accelerate free cash

flow growth, and deliver enhanced returns to shareholders of the combined company.”

STRATEGIC MERGER WITH COTERRA ENERGY

On Feb. 2, 2026, Devon announced that it had entered into an agreement to combine in an all-stock merger with Coterra

Energy.

The combination will create one of the largest shale operators in the world with an asset base anchored by a premier position in the economic core

of the Delaware Basin. The go-forward company, to be named Devon Energy, is expected to unlock substantial value for shareholders by leveraging enhanced scale to improve margins, increase free cash flow, and

accelerate cash returns through the capture of $1.0 billion in sustainable annual pre-tax synergies, expected to be fully achieved by year-end 2027.

Shareholders of both companies approved the transaction on May 4, 2026, and the merger is expected to close on or around May 7, 2026. Upon

completion of the transaction, Devon shareholders will own approximately 54 percent of the combined company and Coterra shareholders will own approximately 46 percent of the combined company on a fully diluted basis.

FINANCIAL RESULTS

Devon reported net earnings of

$120 million, or $0.19 per diluted share, in the first quarter of 2026. Adjusting for items analysts typically exclude from estimates, the company’s core earnings were $641 million, or $1.04 per diluted share.

Devon’s operating cash flow totaled $1.7 billion in the first quarter. The company funded its

capital requirements and had $816 million in free cash flow for the quarter.

At the end of the first quarter, Devon had a cash balance of

$1.8 billion and an undrawn credit facility of $3.0 billion. Outstanding debt totaled $8.4 billion and the company’s net debt-to-EBITDAX ratio was

RETURN OF CAPITAL

Devon has not yet

declared a quarterly dividend during the second quarter due to the pending merger with Coterra Energy. Following the closing of the merger and subject to Board approval, the company expects to declare a quarterly dividend for the second quarter of

The company returned capital to shareholders through the ongoing execution of its $5.0 billion share repurchase program. During

the first quarter, Devon repurchased shares for $69 million. In connection with the pending merger with Coterra Energy, the company has suspended share repurchasing activity through the expected closing.

Following the closing of the merger with Coterra Energy, the company expects to establish a new share repurchase authorization in excess of $5 billion,

subject to Board approval.

OPERATING RESULTS

Devon’s capital activity in the first quarter averaged 19 operated drilling rigs and 6 completion crews across its asset portfolio. This level of

activity resulted in 110 gross operated wells being placed online, with an average lateral length of 10,500 feet. Capital investment, excluding acquisition capital, was $848 million, or 6 percent below guidance. This positive variance was

primarily attributable to effective cost management and timing of facility spend. The company also completed $151 million in leasehold acquisitions, primarily in the Delaware Basin, across its portfolio.

Production averaged 833,000 Boe per day in the first quarter, in line with guidance. Oil totaled 387,000 barrels per day in the quarter, which was

46 percent of total volume and at the top-end of the company’s guidance.

Underpinning these results is

the continued strong progress in advancing the company’s business optimization plan. With strong momentum established, the company expects to fully achieve its $1 billion annual pre-tax free cash

flow improvement target well ahead of schedule with the upcoming repayment of the $1 billion term loan. These actions will continue to strengthen margins and maximize capital efficiency across Devon’s assets.

On a Devon standalone basis, G1production

in the second quarter of 2026 is expected to average 851,000 to 868,000 Boe per day (46 percent oil). G2Capital spending in the second quarter is expected to be approximately $900 million.

Given the expected closing of the merger with Coterra Energy, the company is not providing full-year 2026 guidance at this time. Guidance for the combined

entity will be provided in mid-June 2026.
