ST. JOHN'S, NEWFOUNDLAND AND LABRADOR--(Marketwired - March 26, 2018) - Fortis Inc. ("Fortis" or the "Corporation") (TSX:FTS) (NYSE:FTS) announced today that it has established an at-the-market equity program (the "ATM Program") that allows 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.

The ATM Program will be effective until December 30, 2018 unless terminated prior to such date by the Corporation.
