HYDRO ONE INC. PRICES OFFERING OF $400 MILLION MEDIUM TERM NOTES UNDER SUSTAINABLE FINANCING FRAMEWORK

Hydro One Ltd.'s wholly owned subsidiary, Hydro One Inc., has priced an offering of $400-million aggregate principal amount of 4.85 per cent medium-term notes, Series 58, due 2054. The net proceeds from the issuance of the notes will be approximately $398-million. The offering of the notes is expected to close on Nov. 30, 2023.

The offering of notes represents Hydro One's fourth issuance of medium-term notes pursuant to its Sustainable Financing Framework dated Jan. 23, 2023, and Hydro One's third issuance of green bonds under the framework. Hydro One intends to allocate an amount equal to the net proceeds from the sale of the notes to finance and/or refinance, in whole or in part, new and/or existing eligible green projects that meet the eligibility criteria described in the framework. Prior to such allocation, the net proceeds may be initially used, in part or in full, for repayment of indebtedness or investments in bank deposits or other cash equivalents, in each case in accordance with Hydro One's internal liquidity management policies. Although Hydro One intends to allocate an amount equal to the net proceeds from the sale of the notes to eligible green projects under the framework, it will not be an event of default under the trust indenture governing the applicable notes if the company fails to do so.

The notes are being offered on a best effort basis in each of the provinces of Canada through a syndicate of agents. The notes are being offered pursuant to a short form base shelf prospectus of Hydro One dated June 3, 2022. Hydro One will be filing a pricing supplement to the base shelf prospectus relating to the offering of the notes with the securities regulatory authorities in each of the provinces of Canada. The pricing supplement and accompanying base shelf prospectus contain important detailed information about the notes being offered. A copy of the pricing supplement and the accompanying base shelf prospectus relating to the notes may be obtained over the Internet under Hydro One's profile at the Canadian Securities Administrators' website at SEDAR+. Investors should read the pricing supplement and accompanying base shelf prospectus before making an investment decision.
