Spectra Energy Corp.’s (NYSE: SE) stock jumped more than 13% in early trading Sept. 6 following the announcement of the company’s $28 billion sale to Enbridge Inc. (NYSE: ENB).

The all-stock deal melds Calgary, Alberta-based Enbridge’s 17,150 miles of North American crude oil pipelines with Houston-based Spectra’s 17,100 miles of long-haul natural gas pipelines. This allows the new company, to be called Enbridge Inc., to instantly become a gas-transporting powerhouse at a time when resistance from environmentalists has added to the typical challenges of organic growth.

Al Monaco, CEO of Enbridge Inc. Spectra represents an “extension of the runway,” Enbridge CEO Al Monaco said during a conference call with analysts. “We all know it’s pretty difficult to execute projects these days.”

Monaco will be CEO of the combined company, which would have a market capitalization of about $69.5 billion and be based in Calgary. Spectra CEO Greg Ebel will serve as chairman.

The transaction, when approved as expected in first-quarter 2017, will unite the Nos. 6 and 7 companies on Hart Energy’s Midstream 50 list, which ranks the sector’s players based on previous year’s EBITDA. Enbridge’s EBITDA for 2015 was $2.8 billion; Spectra’s was $2.75 billion.

Based on The Midstream 50, the new company’s total assets will be about $94 billion, surpassing Kinder Morgan Inc.’s (NYSE: KMI) roughly $84 billion to lead the ranking.

In market cap and enterprise value, the new Enbridge would not only lead all public companies in the midstream, but would become the fourth-largest Canadian company and the ninth-largest energy company in the world, according to an investor presentation.

Enbridge’s offer represents a premium of about 11.5% above Spectra’s closing stock price of Sept. 2. About 694 million new units will be issued, with Enbridge unitholders owning 57% of the new company and $22 billion of Spectra’s existing debt assumed by Enbridge.

The deal follows TransCanada Corp.’s (NYSE: TRP) announced acquisition of Columbia Pipeline Group Inc. (NYSE: CPGX) in March, continuing a consolidation trend of midstream majors seeking to leverage their size as they work their way through the downturn.
