DEVON ENERGY CORP/DE

The amount of income taxes recorded requires interpretations of complex rules and regulations of federal, state, provincial and foreign tax jurisdictions. We recognize current tax expense based on estimated taxable income for the current period and the applicable statutory tax rates. We routinely assess potential uncertain tax positions and, if required, estimate and establish accruals for such amounts. We have recognized deferred tax assets and liabilities for temporary differences, operating losses and other tax carryforwards. We routinely assess our deferred tax assets and reduce such assets by a valuation allowance if we deem it is more likely than not that some portion or all of the deferred tax assets will not be realized.

On July 4, 2025, OBBB was signed into law. In addition to other provisions, OBBB includes permanent reinstatement of 100% bonus depreciation and the expensing of domestic research costs beginning in 2025 and allows for deduction of intangible drilling costs as part of the computation of the CAMT beginning in 2026. On February 18, 2026, the IRS issued additional interim CAMT guidance through Notice 2026-7. In addition to other provisions, the Notice includes a new AFSI adjustment beginning in 2025 for amortization of domestic research costs, including accelerated amortization under the OBBB transition rule, the impact of which was recorded in the first quarter of 2026. We continue to monitor for additional OBBB guidance.

Further, in the event we were to undergo an “ownership change” (as defined in Section 382 of the Internal Revenue Code of 1986, as amended), our ability to use net operating losses and tax credits generated prior to the ownership change may be limited. Generally, an “ownership change” occurs if one or more shareholders, each of whom owns five percent or more in value of a corporation’s stock, increase their aggregate percentage ownership by more than 50 percent over the lowest percentage of stock owned by those shareholders at any time during the preceding three-year period. Based on currently available information, we do not believe an ownership change has occurred during first quarter 2026 for Devon.
