NEWS RELEASE

Enbridge Inc. and Enbridge Pipelines Inc. Announce Noteholder Approval of Proposed Debt Exchange Transaction

CALGARY, June 10, 2026 - Enbridge Inc. (TSX: ENB) (NYSE: ENB) (Enbridge) and its wholly owned subsidiary Enbridge Pipelines Inc. (EPI) today announced that EPI has successfully obtained approval for the previously announced transaction to exchange all outstanding series of EPI’s medium term notes debentures (EPI Notes) for an equal principal amount of newly issued medium term notes of Enbridge (Enbridge Notes), having financial terms that are the same as the financial terms of the EPI Notes (the Note Exchange Transaction).

By the consent deadline of June 10, 2026 (Consent Deadline), EPI received sufficient valid written consents from the holders (EPI Noteholders) of EPI Notes to pass an extraordinary resolution approving the Note Exchange Transaction (Note Exchange Resolution). With more than 75% of the total principal amount of outstanding EPI Notes consented in favour, the meeting of EPI Noteholders scheduled for June 25, 2026 is no longer required and has been cancelled.

It is anticipated that the Note Exchange Transaction will be completed on or about June 16, 2026. Following completion of the Note Exchange Transaction, the applicable amendment review fees, as disclosed in the management information circular and consent solicitation statement of EPI dated May 25,2026, will be paid to EPI Noteholders that delivered valid written consent and proxy forms consenting to / voting for or withholding consent / voting against the Note Exchange Resolution by the Consent Deadline.

Enbridge and EPI thank EPI Noteholders for their participation in this process.

For any questions concerning the Consent and Proxy Solicitation Process and the Note Exchange Transaction, EPI Noteholders may continue to contact BMO Capital Markets as solicitation agent by telephone at 1-416-359-6359 or toll-free at 1-833-418-0762 or by email at liabilitymanagement@bmo.com.

NOTICE TO EPI NOTEHOLDERS IN THE UNITED STATES

The Enbridge Notes to be issued in connection with the Note Exchange Transaction have not been registered under the U.S. Securities Act of 1933, as amended (the U.S. Securities Act) and are being issued pursuant to an exemption from the registration requirements of the U.S. Securities Act provided by Rule 802 thereunder.

The Note Exchange Transaction described in this press release is made for the securities of a Canadian corporation. The Note Exchange Transaction is subject to the disclosure requirements of Canada, and EPI Noteholders in the United States (U.S. EPI Noteholders) should be aware that the foregoing disclosure requirements are different from those of the United States.

It may be difficult for U.S. EPI Noteholders to enforce their rights and any claims U.S. EPI Noteholders may have arising under U.S. federal securities laws, since EPI and Enbridge are located in Canada, and many of their officers and directors are residents of Canada. U.S. EPI Noteholders may not be able to sue a Canadian corporation or its officers or directors in a Canadian court for violations of U.S. securities laws. It may be difficult to compel a Canadian corporation and its affiliates to subject themselves to a U.S. court’s judgment.
