FORTIS INC. ANNOUNCES AT-THE-MARKET EQUITY PROGRAM

Fortis Inc. has established an at-the-market equity program that allows the corporation to issue up to $500-million (or the U.S. dollar equivalent) of 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 New York Stock Exchange 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 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 Dec. 30, 2018, 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.
