CALGARY, Alberta--(BUSINESS WIRE)--AltaLink, L.P. (“ALP”) announces that, in connection with its previously announced internal reorganization (the “Internal Reorganization”), it has entered into an amending agreement dated August 27, 2026 (the “Amending Agreement”) with BHE AltaLink Ltd. (“BHEAL”) and certain other wholly-owned direct or indirect subsidiaries of BHEAL (collectively, the “AltaLink Entities”) to amend the arrangement agreement dated July 9, 2026 (the “Arrangement Agreement”) and the plan of arrangement attached thereto (as amended, the “Plan of Arrangement”).

The Amending Agreement, including the Plan of Arrangement attached as Schedule “A” to the Amending Agreement, reflects certain changes to the timing and manner of implementation of certain corporate steps and transactions in connection with the Internal Reorganization (the “Amendments”).

The Amendments are administrative and non-substantive in nature, and the Internal Reorganization will still result in, among other things, AltaLink Ltd. (being the successor to ALP and certain AltaLink Entities under the Plan of Arrangement) becoming the regulated transmission utility and holding, directly or indirectly, all of the assets and liabilities presently held by ALP.

The Amending Agreement is not expected to impact: (a) the application for the final order approving the Internal Reorganization, which is still expected to be heard by the Court of King’s Bench of Alberta (the “Court”) on September 4, 2026, or as soon thereafter as counsel may be heard, or (b) the completion of the Internal Reorganization, which is still expected to be completed in Q4 2026, subject to the receipt of required regulatory, court and other approvals.

A copy of the Amending Agreement, the Plan of Arrangement (attached as Schedule “A” to the Amending Agreement) and the amended notice of originating application will be made available under ALP’s profile on SEDAR+ and ALP’s website, www.altalink.ca. Further details regarding the Internal Reorganization are set out in the notice of originating application and originating application filed with the Court in connection with the Internal Reorganization and the Arrangement Agreement, each of which are also available under ALP’s profile on SEDAR+ and ALP’s website, www.altalink.ca.
