 more detailed description of the Plan’s provisions.

#### General
The Plan is a trusteed defined contribution retirement benefit plan offered to eligible employees of Atmos Energy Corporation (the Company, Atmos Energy or Plan Sponsor). The Plan is to continue for an indefinite term and may be amended or terminated at any time by the Board of Directors of Atmos Energy (the Board). The Plan is administered by the Qualified Retirement Plans and Trusts Committee (the Committee), which is appointed by the Board. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended (ERISA).

#### Eligibility
Substantially all employees of the Company, other than leased employees (Participants), are automatically enrolled in the Plan at a pre-tax salary deferral rate of four percent (4%) of their compensation. Participants have a 30-day period to opt out of automatic enrollment. After 30 days, if the Participant has not opted out or elected a different deferral percentage, salary deferrals begin at the automatic enrollment level of 4%. Effective January 1, 2025, the automatic enrollment level increased from 4% to 5%, and effective January 1, 2026, it will increase from 5% to 6%.

#### Contributions
Contributions to the Plan include contributions withheld by the Company on behalf of each Participant in an amount specified by the Participant pursuant to a salary deferral agreement, as well as matching and fixed annual Company contributions.

Participants may elect a Pre-Tax or Roth deferral rate ranging from a minimum of one percent (1%) up to a maximum of 65 percent (65%) of eligible compensation, as defined by the Plan, not to exceed the maximum allowed by the Internal Revenue Code (the Code) ($23,000 in 2024 or $30,500 for those participants age 50 or older). Additionally, the Plan includes an automatic increase provision where each Participant who contributes less than 10% as an elective pre-tax deferral will have their contribution percent increased by 1% each Plan year unless the Participant opts out of the automatic increase feature.

The Company contributes a matching Company contribution in an amount equal to 100 percent of each Participant’s salary deferral contribution, up to a maximum of 4% of such Participant’s eligible compensation, as defined by the Plan, for the Plan year. The Company’s matching contribution meets the current Internal Revenue Service (IRS) “Safe Harbor” definition. The Company may revoke or amend any Participant’s salary deferral agreement if
