TC PipeLines' common shareholders would receive 0.70 common shares of TC Energy, which represents a 19.5% premium to TC PipeLines' closing price as of Oct. 2, before the initial offer was made.

The deal is expected to close late in the first quarter or early in the second quarter of 2021. TC PipeLines will be wholly-owned by TC Energy and cease to be a publicly-held master limited partnership, once the deal closes.

Keystone pipeline operator TC Energy already owns a 23.96% stake in TC PipeLines, according to Refinitiv data.
