Atmos Energy Corporation has filed a registration statement (including a prospectus) with the SEC for the offering to which this communication relates. Before you invest, you should read the prospectus in that registration statement and other documents the issuer has filed with the SEC for more complete information about Atmos Energy Corporation and this offering. You may get these documents for free by visiting EDGAR on the SEC Web site at www.sec.gov. Alternatively, any underwriter or any dealer participating in the offering will arrange to send you the prospectus if you request it by contacting BNP Paribas Securities Corp. at 1-800-854-5674, CIBC World Markets Corp. at 1-800-282-0822, Credit Agricole Securities (USA) Inc. at 1-866-807-6030, or Wells Fargo Securities, LLC at 1-800-645-3751.

We expect that delivery of the notes will be made against payment therefor on or about March 4, 2019, which will be the fifth business day following the date of the pricing of the notes (such settlement cycle being referred to as “T+5”). Under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended, trades in the secondary market generally settle in two business days, and purchasers who wish to trade notes on the date of pricing or any subsequent date that is prior to the second trading day preceding the date on which we deliver the notes may be required, by virtue of the fact that the notes initially settle in T+5, to specify alternate settlement arrangements to prevent a failed settlement. Purchasers of the notes who wish to trade the notes prior to their date of delivery hereunder should consult their advisers.
