Emera and Canadian Utilities announce $72 billion merger to form Canada’s largest utility company, with ATCO spinning off its industrial services division
Canada’s energy sector got a major headline on October 6, 2026: Emera and Canadian Utilities announced they’re merging in an all-share deal that would create a utility company with roughly C$72 billion ($53 billion) in enterprise value. The companies are calling it the biggest merger in Canadian history between two domestic firms.
The combined company would keep the Emera name, serve around six million customers across Canada, the U.S., and international markets, and land among the top 20 North American utilities.
Deal overview: Terms and structure
The structure is straightforward: Emera acquires all outstanding shares of both Canadian Utilities and ATCO in an all-share transaction. The implied value of the Canadian Utilities acquisition alone comes to approximately C$14.3 billion ($10.5 billion).
Nancy Southern, currently Chair and CEO of ATCO, will lead New ATCO in the same dual roles, with Katie Patrick serving as Chief Financial and Investment Officer.
Exchange ratios vary by share class. Canadian Utilities Class A shareholders get 0.755x Emera common shares, while Class B shareholders get 0.819x. ATCO Class I and Class II shareholders receive 0.865x Emera shares — plus one New ATCO share for each share they hold, giving them a stake in both resulting companies.
When everything settles, existing Emera shareholders are expected to own roughly 60% of the combined company, with former Canadian Utilities and ATCO shareholders holding the remaining 40%.
The combined company keeps the Emera name. Public company headquarters stays in Halifax, with operational offices in Calgary, Edmonton, Tampa, and Perth, Australia — a footprint that reflects just how geographically spread out its regulated businesses are. Scott Balfour will serve as CEO, with Nancy Southern and Karen Sheriff as Co-Chairs of the Board.
Why the companies pursued the merger
The logic here is about scale. Energy infrastructure investment across North America is accelerating — driven by electrification, large industrial customers, and major transmission upgrades — and neither company could meet those capital demands as effectively on its own.
Together, the combined entity would generate approximately 95% of its earnings from regulated utilities, which means a high degree of earnings predictability. About 80% of those earnings would come from Florida and Alberta, two of the fastest-growing utility jurisdictions on the continent, according to both companies.
The merger is also expected to strengthen the combined company’s credit profile. Better credit ratings translate into lower borrowing costs and more flexibility to deploy capital — and that matters considerably when heavy spending is on the horizon.
The companies have outlined a C$32 billion capital plan through 2030, targeting average annual rate base growth of 7% to 8%. That kind of investment program needs the financial muscle that comes with a combined C$45 billion rate base and a C$72 billion enterprise value.
ATCO’s spin-off into New ATCO
Running alongside the merger is a separate but connected move: ATCO will spin off its industrial services operations into a new standalone public company called New ATCO.
New ATCO will include ATCO’s housing, defence, ports, and retail energy businesses — operations that don’t fit neatly inside a regulated utility structure. It’ll incorporate in Alberta and be headquartered in Calgary, built to pursue growth in housing affordability, defence readiness, and critical infrastructure under its own dedicated leadership and capital focus.
ATCO shareholders don’t have to choose between the two paths. They receive one New ATCO share for each ATCO share they currently hold, on top of their Emera shares from the main transaction. Nancy Southern, currently Chair and CEO of ATCO, will lead New ATCO in the same dual roles, with Katie Patrick serving as Chief Financial and Investment Officer. New ATCO will carry a dual-class share structure mirroring ATCO’s existing setup, with Sentgraf Enterprises retaining all voting shares.
Regulatory approvals and expected timeline
Closing this deal won’t be fast. It requires approvals from shareholders of all three companies, the Court of King’s Bench of Alberta, the Alberta Utilities Commission, the U.S. Federal Energy Regulatory Commission, and the Competition Bureau of Canada. Separate notifications or approvals are also required in Australia, Mexico, and the U.S. under several additional regulatory frameworks.
That’s a long list — but one key early commitment is already secured. Sentgraf Enterprises, which controls approximately 27% of ATCO’s non-voting shares and all of its voting shares, has signed a voting support agreement backing the transaction. All directors and executive officers of Emera, ATCO, and Canadian Utilities have done the same.
Special shareholder meetings are expected in early 2027. If everything stays on schedule, the deal is projected to close in the third or fourth quarter of 2027.
What you need to know: The companies and the sector
Emera is listed on both the TSX and NYSE and currently serves approximately 2.1 million customers across the U.S., Canada, and the Caribbean. About 70% of its earnings come from Florida operations, where Tampa Electric is its flagship utility.
Canadian Utilities is an ATCO subsidiary serving customers in Canada, Mexico, Australia, and Puerto Rico, with approximately 80% of its earnings tied to Alberta. The two companies bring complementary geographic footprints and a combined portfolio of 12 regulated utilities.
The deal reflects a broader trend reshaping the Canadian utility sector: mounting capital requirements for grid modernization and electrification are pushing companies toward consolidation, because staying competitive at scale increasingly demands exactly that — scale.
