Fortis Inc. to Renew At-The-Market Equity Program

Fortis Inc. ("Fortis" or the "Corporation") (TSX/NYSE: FTS) announced that it will renew its at-the-market equity program (the "ATM Program") allowing the Corporation to issue up to C$500,000,000 (or its U.S. dollar equivalent) of common shares (the "Common Shares") from treasury to the public from time to time, at the Corporation's discretion. Any Common Shares sold in the ATM Program will be sold through the Toronto Stock Exchange (the "TSX"), the New York Stock Exchange (the "NYSE") or any other marketplace on which the Common Shares are listed, quoted or otherwise traded at the prevailing market price at the time of sale.

The ATM Program provides Fortis with additional financing flexibility to fund its capital program. The volume and timing of distributions under the ATM Program, if any, will be determined at the Corporation's sole discretion. The ATM Program will be effective until January 10, 2027, unless terminated prior to such date by the Corporation. Fortis intends to use the net proceeds from the ATM Program, if any, for general corporate purposes. As Common Shares sold in the ATM Program will be distributed at the prevailing market price at the time of the sale, prices may vary among purchasers during the period of the distribution.

Distributions of the Common Shares through the ATM Program will be made pursuant to the terms of an equity distribution agreement dated December 9, 2024 (the "Equity Distribution Agreement") entered into with CIBC World Markets Inc., RBC Dominion Securities Inc., Scotia Capital Inc. and TD Securities Inc., as Canadian agents (the "Canadian Agents"), and CIBC World Markets Corp., RBC Capital Markets, LLC, Scotia Capital (USA) Inc. and TD Securities (USA) LLC, as U.S. agents (together with the Canadian Agents, the "Agents").

The ATM Program is being established pursuant to: (a) a prospectus supplement dated December 9, 2024 (the "Prospectus Supplement") to the Corporation's Canadian short form base shelf prospectus (the "Shelf Prospectus") filed today with securities regulatory authorities in each of the provinces of Canada; and (b) a prospectus supplement dated December 9, 2024 (the "U.S. Prospectus Supplement") to the Corporation's U.S. base prospectus (the "U.S. Base Prospectus") included in its U.S. registration statement on Form F-10 (the "Registration Statement") filed today with the U.S. Securities and Exchange Commission. The Corporation's at-the-market equity program, which commenced on September 19, 2023, terminated upon filing of the Shelf Prospectus.

The Prospectus Supplement, the Shelf Prospectus and the Equity Distribution Agreement will be available on SEDAR+ at www.sedarplus.ca. The U.S. Prospectus Supplement, the U.S. Base Prospectus and the Registration Statement will be available on EDGAR at www.sec.gov. Alternatively, the Agents will send copies of the Prospectus Supplement and the Shelf Prospectus or the U.S. Prospectus Supplement and the U.S. Base Prospectus, as applicable, upon request by contacting in Canada:
