Devon Energy Officer Power of Attorney for Section 16 Filings

This SEC Form 3 filing documents a power of attorney granted by Michael D. DeShazer, Executive Vice President of Exploration & Production at Devon Energy Corporation. The power of attorney authorizes four designated attorneys-in-fact (Adam M. Vela, Marcus G. Bolinder, Christopher J. Kirt, and Edward T. Highberger) to execute and file Forms 3, 4, and 5 on DeShazer's behalf in connection with Section 16 reporting requirements. The document grants comprehensive authority including EDGAR system enrollment, Form ID preparation, account management, and execution of all necessary Section 16 filings. The power of attorney became effective on May 7, 2026, and supersedes any previous similar powers of attorney.
