Alterra shareholders will hold a 19 per cent stake in the combined company and one member of the current Alterra board will join the Innergex board once the transaction is completed.

The transaction requires approval by a two-thirds majority vote by Alterra shareholders at a meeting that is expected to be held in December.

In addition, the deal is subject to court and certain regulatory approvals in Canada and U.S., key third-party consents and other customary closing conditions.
