TRP TC Energy Corporation

News Release – TC Energy Corporation (TSX, NYSE: TRP) (TC Energy or Company) today announced that it has established an at-the-market equity program (ATM Program) that allows the Company to issue common shares from treasury (Common Shares) having an aggregate gross sales price of up to $1.0 billion, or its U.S. dollar equivalent, to the public from time to time, at the Company’s discretion, at the prevailing market price when sold through the Toronto Stock Exchange (TSX), the New York Stock Exchange (NYSE) or any other applicable existing trading market for the Common Shares in Canada or the United States (ATM Offering). The formal establishment of the ATM Program, which is effective for a 25-month period, is consistent with the intent to do so announced by the Company in conjunction with its decision to proceed with Keystone XL in March 2020. While not a component of the Company’s base funding plan, it provides additional financial flexibility in support of TC Energy’s consolidated credit metrics and capital program, including the Keystone XL Pipeline Project, and may be activated if and as deemed appropriate.

The Common Shares will be distributed at the prevailing market prices at the time of their sale and, as a result, prices may vary among purchasers and during the period of distribution.
