In connection with the vesting on September 16, 2026 of performance shares previously granted to the reporting person, the reporting person's receipt of 478 shares of common stock was deferred, resulting in the reporting person's receipt instead of 478 deferred stock units pursuant to National Fuel Gas Company's deferred compensation plan. The reporting person is therefore reporting the disposition of 478 shares of common stock in exchange for an equal number of deferred stock units. The NFG stock fund under the NFG 401(k) plan is denominated in units, representing ownership interests in a fund that includes both NFG common stock and a reserve of cash. The information reported represents the dollar value of the reporting person's balance in the NFG stock fund as of September 16, 2026, as reported by the plan administrator, divided by the closing price of NFG common stock on that date. Acquired through dividend reinvestment feature of the National Fuel Gas Company Deferred Compensation Plan for Directors and Officers, exempt under Rule 16a-11. Each deferred stock unit is the economic equivalent of one share of common stock. The deferred stock units become payable, in shares of common stock, after the reporting person's termination of service, pursuant to the reporting person's distribution election under National Fuel Gas Company's Deferred Compensation Plan for Directors and Officers.
