On March 3, 2023, Atmos Energy Corporation entered into a Term Loan Agreement (the “Term Loan Agreement”) with (i) U.S. Bank National Association (“U.S. Bank”), as the Administrative Agent, (ii) Mizuho Bank Ltd. (“Mizuho”), as Syndication Agent, (iii) CoBank, ACB (“CoBank”), as Documentation Agent, (iv) U.S. Bank, Mizuho and CoBank, as Joint Lead Arrangers and Joint-Bookrunners, and (v) the lenders named therein, providing the Company with a $2.02 billion senior unsecured term loan facility (the “Term Loan Facility”). Proceeds of the Term Loan Facility will be used by the Company to repay at maturity the Company's outstanding senior notes that mature on March 9, 2023. The Term Loan Facility will bear interest at a rate equal to either, at the Company's election, the alternate base rate plus a 0.00% margin or the Term SOFR rate for the applicable interest period plus an applicable margin of 0.95%.

The alternate base rate is defined as the highest of (i) zero, (b) a per annum rate of interest equal to the to the prime rate of interest announced by U.S. Bank from time to time, (ii) the Federal Funds Rate, as in effect at the time of borrowing, plus 0.50% per annum, or (iii) the one-month Term SOFR screen rate for US Dollars plus 1.00%. The Term SOFR rate is the forward-looking term rate based on the secured overnight financing rate published by the Federal Reserve Bank of New York. The Company may elect the Term SOFR rate applicable to one-month, three-month or six-month Interest Periods.

The Term Loan Facility is initially accruing interest based on the Term SOFR rate for a three-month interest period, which is an effective total interest rate of 5.955600% per annum. The Term Loan Facility will mature on December 31, 2023, at which time all outstanding amounts under the Term Loan Facility will be due and payable. The Company is required to prepay the Term Loan Facility prior to maturity upon receiving proceeds from the issuance of certain securities that are part of a utility recovery securitization transaction authorized by the applicable regulatory authorities of the states of Texas and Kansas.

The Company may otherwise voluntarily prepay all or any portion of the Term Loan Facility at any time. The Term Loan Facility contains usual and customary covenants for transactions of this type, including covenants limiting liens, substantial asset sales and mergers. In addition, the Term Loan Facility provides that during the term of the facility, the Company's debt to capitalization ratio as of the last day of each of its fiscal quarters shall be less than or equal to 0.70 to 1.00, excluding from the calculation of debt (i) any pension and other post-retirement benefits liability adjustments recorded in accordance with generally accepted accounting principles; and (ii) an amount of hybrid securities, as defined in the Credit Facility (generally, deferrable interest subordinated debt with a maturity of at least 20 years), not to exceed a total of 15% of total capitalization.

In the event of a default by the Company under the Term Loan Facility, including cross-defaults relating to specified other indebtedness of the Company, U.S. Bank may, upon the consent of lenders holding a certain minimum of loans, and shall, upon the request and direction of such lenders, declare the amounts outstanding under the Term Loan Facility, including all accrued interest and unpaid fees, payable immediately, and enforce any and all rights and interests created and existing under the Term Loan Facility documents, including, without limitation, all rights of set-off and all other rights available under the law. For certain events of default relating to insolvency, bankruptcy or receivership, the amounts outstanding under the Term Loan Facility automatically become payable immediately.
