Item 1.01 Entry into a Material Definitive Agreement

Shareholder Rights Plan

At the 2026 Annual Meeting of Shareholders held on May 6, 2026 (the “Annual Meeting”), the holders of common shares of Enbridge Inc. (the “Corporation”) voted to amend, reconfirm and approve the Corporation’s shareholder rights plan (the “Rights Plan”) under the terms of an agreement between the Corporation and Computershare Trust Company of Canada (“Computershare”), as rights agent. The Rights Plan originally became effective on November 9, 1995, and pursuant to its terms is required to be reconfirmed and approved by a majority of shareholders every three years or it will be terminated and cease to have effect.

The amendments to the Rights Plan approved at the Annual Meeting provide that the Rights Plan must next be approved at the annual meeting of shareholders held three years after the Annual Meeting or the Rights Plan will cease to have effect, and include certain other non-material changes to the Rights Plan.

The Rights Plan encourages the fair treatment of shareholders if there is a take-over bid for control of the Corporation. Rights issued under the Rights Plan become exercisable when a person and any related parties acquire or announce the intention to acquire 20% or more of the Corporation’s outstanding common shares without complying with certain provisions set out in the Rights Plan or without approval of the board of directors of the Corporation (the “Board”). Should such an acquisition or announcement occur, each rights holder, other than the acquiring person and its related parties, will have the right to purchase common shares of the Corporation at a 50% discount to the market price at that time.

The foregoing summary of the Rights Plan and the amendments thereto does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Rights Plan, which is attached as Exhibit 4.1 to this Current Report on Form 8-K and is incorporated herein by reference.

Item 3.03 Material Modification to Rights of Security Holders

The information set forth in Item 1.01 of this Current Report on Form 8-K is incorporated into this Item 3.03 by reference.

Item 5.07. Submission of Matters to a Vote of Security Holders

At the Annual Meeting, the holders of common shares of the Corporation voted on: (1) 12 director nominees to be elected to the Board to serve until the close of the Corporation’s next annual meeting of shareholders or until their respective successors have been appointed or elected; (2) the appointment of PricewaterhouseCoopers LLP as independent auditors of the Corporation until the close of the Corporation’s next annual meeting of shareholders at such remuneration to be fixed by the Board; (3) an advisory vote on the Corporation’s approach to executive compensation (a “say on pay vote”); and (4) the amendment, reconfirmation and approval of the Rights Plan under the terms of an agreement between the Corporation and Computershare. The items of business are further described in the Corporation’s management information circular (the “Circular”) filed as Exhibit 99.1 to the Corporation’s Current Report on Form 8-K filed with the U.S. Securities and Exchange Commission on March 10, 2026.

The tables below set forth the number of votes cast for, against or withheld, and the number of abstentions and broker non-votes, for each matter voted on by the Corporation’s shareholders.

Each of the 12 nominees listed below was elected as Director of the Corporation to hold office until the close of the Corporation’s next annual meeting of shareholders or until their successor is appointed or elected.

2. Appoint PricewaterhouseCoopers LLP as Independent Auditors

The shareholders approved the appointment of PricewaterhouseCoopers LLP as independent auditors of the Corporation until the close of the Corporation’s next annual meeting of shareholders at such remuneration to be fixed by the Board.

3. Advisory Vote on the Corporation’s Approach to Executive Compensation

The shareholders approved the non-binding advisory resolution regarding the Corporation’s approach to executive compensation, as disclosed in the Circular.

4. Amendment, Reconfirmation and Approval of the Shareholder Rights Plan
