The combined company is expected to have a pro forma enterprise value of approximately $72 billion, approximately $45 billion in rate base and serve approximately six million customers across Canada, the United States and international markets. It will have greater financial strength, broader capabilities, and enhanced investment capacity to support expected growing energy and infrastructure needs across its operations. This increased scale will position the company to support a range of capital-intensive priorities, electrification projects, major natural gas and electric transmission investments, large load customers, export infrastructure and other large-scale energy infrastructure projects.

The new company will operate as Emera. Its public company headquarters will remain in Halifax, while maintaining Canadian Utilities’ corporate and operational headquarters in Calgary and Edmonton, with a strong continued presence in Canadian Utilities’ key markets including Perth, Australia. Emera’s U.S. operations will continue to be headquartered in Tampa, Florida.

Based on the implied enterprise value of Canadian Utilities, the transaction is expected to be the largest merger in history between two Canadian companies and will form a Top 20 North American utility.

Customers can expect continued safe and reliable service throughout the transaction process and beyond. Until closing, Emera, ATCO and Canadian Utilities will continue to operate independently and remain focused on customers, employees, safety, reliability and operational performance. The combination is expected to support continued investment in infrastructure, employment, economic development, and long-standing community partnerships.

In connection with the transaction, ATCO will spin off into a high-growth industrial services company focused on housing, defence, and investments, including ports and retail energy, into a new publicly-traded company, New ATCO, with a clear growth agenda and distinct investor proposition.

Terms of Agreement

Under the terms of the arrangement agreement, Emera will acquire all the issued and outstanding shares of Canadian Utilities and ATCO, and the transaction will be structured such that ATCO’s industrial services business will be spun-out as New ATCO. Emera will acquire all of the issued and outstanding shares of Canadian Utilities and ATCO for the following consideration:

Canadian Utilities Class A shareholders, other than ATCO, will receive 0.755x of an Emera common share for each Canadian Utilities Class A share held;
Canadian Utilities Class B shareholders, other than ATCO, will receive 0.819x of an Emera common share for each Canadian Utilities Class B share held;
ATCO Class I and Class II shareholders will receive 0.865x of an Emera common share for each Class I or Class II share held. This exchange ratio reflects (i) the same 0.755x exchange ratio for the Canadian Utilities Class A shares held by ATCO; and (ii) the same 0.819x exchange ratio for the Canadian Utilities Class B shares held by ATCO, as adjusted for certain liabilities assumed by Emera and the value of certain Emera shares that will be issued to New ATCO as part of the spinoff transaction.
In addition to the Emera shares, ATCO shareholders will also receive one New ATCO Class I share for each ATCO Class I share held and one New ATCO Class II share for each ATCO Class II share held. All of the voting shares of New ATCO will be distributed to ATCO's sole Class II voting shareholder, Sentgraf, while the non-voting shares of New ATCO will be distributed to existing ATCO Class I non-voting shareholders on a pro rata basis.

Building a Canadian-headquartered energy and infrastructure powerhouse

Demand for safe, reliable and resilient energy infrastructure is accelerating across North America. The combination of Emera and Canadian Utilities will create a larger, more diversified company with the financial capacity, operating expertise and market access to pursue larger and more complex opportunities. Together, the companies are expected to be even better positioned to invest, execute, and compete than either is today.

The combination of Emera, with approximately 70% of earnings from operations in Florida, and Canadian Utilities with approximately 80% from operations in Alberta, creates a company with approximately 95% of earnings from regulated utilities, and approximately 80% of earnings generated in Florida and Alberta, two of the highest growth jurisdictions in North America.

Leadership perspectives

"Today marks an important moment for our companies and the customers and communities we serve," said Scott Balfour, President and Chief Executive Officer of Emera. "This merger creates a Canadian utility and energy infrastructure powerhouse with the scale, financial capacity and expertise to invest in the systems our customers will rely on for decades. As demand rises from electrification trends and major infrastructure development, the combined company will be better positioned to help meet growing energy needs and power Canada’s growth ambitions. Our shared commitment to safety, employees, customers and communities will guide us as we bring our organizations together."

"Over the years, the Emera Board has proudly supported the company’s growth and embraced transformative opportunities that had the potential to create lasting value," said Karen Sheriff, Chair of the Board of Emera. "We believe this is one of those opportunities. Bringing together Emera and Canadian Utilities is a rare chance to build on the strengths of two successful companies and create an even stronger enterprise, with greater capacity to invest, grow and help meet the evolving needs of customers and communities. The Board enthusiastically supports this combination and believes it will create lasting value for shareholders, customers, employees and communities for years to come."

"This transaction represents a defining next chapter for ATCO," said Nancy Southern, Chair and Chief Executive Officer of ATCO. "For nearly eight decades, our people have built businesses that provide essential infrastructure and services to communities and countries. Today, we are creating a structure that we believe unlocks the full growth potential of these businesses and positions them to play an even greater role in powering the future."

"ATCO shareowners will participate in two focused and compelling companies. The combined Emera/Canadian Utilities company will have the scale, capabilities and capital to invest in critical energy and infrastructure projects that support growing demand, while New ATCO will be positioned to accelerate growth in housing, defence and industrial services. Together, these companies are expected to be better equipped to pursue opportunities created by economic growth, infrastructure expansion and increasing focus on security and resilience, creating long-term value for shareowners and Canadians alike."

"This merger is about unlocking the next wave of growth for Canadian Utilities and the customers and communities we serve," said Bob Myles, Chief Executive Officer, Canadian Utilities Limited. "By bringing Canadian Utilities and Emera together, we will combine complementary strengths, proven operating expertise and greater financial capacity to invest in the energy infrastructure needed for the future. We believe that the result will be a stronger, more resilient company—one that is better positioned to pursue new opportunities, support our people and communities, and deliver long-term value for shareholders."

Combination of Emera and Canadian Utilities

The merger of equals will be carried out through an acquisition by Emera of all the outstanding shares of Canadian Utilities, valued at approximately $14.3 billion. The transaction is structured as an all-share transaction, enabling Canadian Utilities’ shareholders to participate in the governance and future direction of a larger, more geographically diversified energy and utilities company, while ATCO shareowners will receive shares of both the combined company and New ATCO.

ATCO and Canadian Utilities non-voting shareholders will receive Emera voting common shares, enabling them to participate in the governance and future direction of the combined company. Canadian Utilities preferred shares will remain outstanding, and no fractional Emera shares will be issued.

Following completion of the transaction, existing Emera shareholders are expected to collectively own approximately 60% of the combined company, while former ATCO and Canadian Utilities shareholders are expected to collectively own approximately 40%. The share-for-share structure provides shareholders with continued participation in the combined company’s expected enhanced scale, geographic diversification, financial flexibility and long-term earnings and dividend growth potential.

Industry-leading management and governance

Upon closing, the merged company will be led by Scott Balfour, President and Chief Executive Officer of Emera. Key members of the current Canadian Utilities leadership team will join the Emera Executive team including Bob Myles as Chief Executive Officer of Canadian Utilities and Becky Penrice as Executive Vice President, Corporate Transformation and Integration. Leadership of the companies’ operating businesses will remain unchanged.

The combined company will have a thirteen-member Board of Directors, with six directors put forward by Canadian Utilities and seven directors put forward by Emera. Nancy Southern will serve as Co-Chair of the Emera Board of Directors alongside Karen Sheriff, the current Chair.

Unlocking ATCO’s next chapter of growth

In connection with the transaction, ATCO will spin off as a high-growth industrial services company as New ATCO, a newly formed public company focused on housing, defence and investments, including ports and retail energy. New ATCO will emerge as a purpose-built company with dedicated leadership, capital and strategic focus, positioned to build, deploy and operate in complex environments across North America and international markets.

ATCO shareowners will therefore hold interests in two focused public companies: New ATCO, aligned with global housing, defence and investment growth trends, and the combined Emera-Canadian Utilities company, a Canadian-headquartered utility and energy infrastructure powerhouse positioned at the centre of North America’s energy future.

As governments and industry invest in housing affordability, defence readiness, critical infrastructure and economic security, New ATCO will be positioned to pursue these opportunities with the flexibility and focus of a standalone company. Built on nearly 80 years of operating and investment experience, its customer relationships, remote capabilities and disciplined approach to capital deployment are expected to provide a strong foundation for organic and acquisition-led growth—and a clearer path to long-term value recognition.

New ATCO will continue with global operations with headquarters in Calgary, Alberta. Nancy Southern will serve as Chair and Chief Executive Officer and Katie Patrick will serve as Chief Financial & Investment Officer.

New ATCO will have a dual class share structure similar to ATCO's, with a class of voting shares and a class of non-voting shares which have the same economic entitlements as the voting shares. All of the voting shares will be distributed to ATCO's sole voting shareowner, Sentgraf, while the non-voting shares will be distributed to existing ATCO non-voting shareowners on a pro rata basis.

Independent process and Board approval

The transaction is the result of a comprehensive review process overseen by the directors of Emera, directors of ATCO who are fully independent from ATCO’s controlling shareholder, and directors of Canadian Utilities who are fully independent from ATCO. ATCO and Canadian Utilities each appointed a separate special committee of independent directors to negotiate, examine, review and evaluate the merits and risks of the transaction and make recommendations to their respective boards.

Gordon Dyal & Co. provided a fairness opinion to the Board of Directors of ATCO that, based upon and subject to the assumptions, limitations and qualifications to be set forth in its written opinion, the consideration to be received by ATCO shareholders (other than Sentgraf and certain of its affiliates) pursuant to the arrangement is fair, from a financial point of view, to such shareholder. The ATCO Special Committee received a fairness opinion from CIBC World Markets Inc. with respect to the fairness (as of the date of such opinion and subject to the assumptions, limitations and qualifications set forth therein), from a financial point of view, of the consideration to be received by ATCO shareowners (other than Sentgraf and certain of its affiliates), pursuant to the arrangement agreement.

The Canadian Utilities’ Special Committee received a fairness opinion from BMO Capital Markets with respect to the fairness, from a financial point of view, of the consideration to be received by Canadian Utilities shareholders (other than ATCO and certain of its affiliates and other related parties) pursuant to the arrangement. Lazard and Scotiabank each provided fairness opinions to the Board of Directors of Emera with respect to the fairness, of the consideration to be paid by Emera pursuant to the arrangement, from a financial point of view.

Following the recommendations of their respective special committees, each of the boards of ATCO and Canadian Utilities unanimously, with interested directors abstaining, determined that the transaction is in the best interests of ATCO and Canadian Utilities, respectively, approved the transaction and resolved to recommend that securityholders vote in favour of the transaction. Emera’s board also unanimously determined that the transaction is in the best interest of Emera and resolved to recommend that securityholders vote in favour of the transaction.

Voting support agreements

Sentgraf, which holds approximately 27% of the outstanding non-voting shares and all outstanding voting shares of ATCO, has entered into a voting support agreement pursuant to which it has irrevocably agreed to vote its ATCO shares in favour of the transaction, and against any competing acquisition proposals.

In addition, each of the directors and executive officers of ATCO have entered into voting support agreements agreeing to vote their ATCO shares in favour of the continuance and the transaction.

Timing and conditions to closing

Completion of the transaction is subject to the satisfaction of customary conditions, including applicable shareholder, court and regulatory approvals. The transaction is expected to close in the third or fourth quarter of 2027.

Shareholder approvals

The transaction will be effected by way of a court-approved plan of arrangement under the Canada Business Corporations Act. The arrangement will require approvals from ATCO and Canadian Utilities securityholders at special meetings to be called in connection with the transaction. On each such resolution, all applicable ATCO and Canadian Utilities securityholders (including holders of non-voting shares, options and SARs) are entitled to one vote for each security held. In order to proceed, the arrangement must be approved by:

at least two-thirds of the votes cast by holders of ATCO Class I and Class II shares, voting together as a single class;
at least two-thirds of the votes cast by holders of ATCO Class I and Class II shares, ATCO options and ATCO SARs, voting together as a single class;

at least two-thirds of the votes cast by holders of Canadian Utilities Class B shares;
at least two-thirds of the votes cast by holders of Canadian Utilities Class A and Class B shares, Canadian Utilities options and Canadian Utilities SARs, voting together as a single class;
a simple majority of the votes cast by the holders of Canadian Utilities Class A shares, excluding votes required to be excluded under Multilateral Instrument 61-101 – Protection of Minority Security Holders in Special Transactions; and

In each case by applicable holders present or represented by proxy at the applicable meeting, and such other approvals as may be required under applicable securities laws or by the Court of King’s Bench of Alberta in connection with the arrangement.

As part of the transaction, ATCO Class I and Class II shareholders will be asked to approve moving ATCO to a federal corporation, which is a technical step needed to complete the arrangement. New ATCO is a separate company that is being incorporated in Alberta and will remain an Alberta company headquartered in Calgary. The continuance will require approval by two-thirds of the votes cast by holders of ATCO Class I and Class II common shares present or represented by proxy at the ATCO special meeting, voting together as a single class (with one vote per share). The arrangement will not proceed unless the continuance is approved.

Court and regulatory approvals

The transaction is subject to the receipt of all required court, regulatory and stock exchange approvals, including approval of the Court of King’s Bench of Alberta, the Alberta Utilities Commission, the U.S. Federal Communications Commission, the U.S. Federal Energy Regulatory Commission, Comisión Nacional Antimonopolio of Mexico, the Toronto Stock Exchange and the New York Stock Exchange, as well as any required confirmation or approval from the Northwest Territories Public Utilities Board, and approvals or notifications under the Competition Act (Canada), the Canada Transportation Act, the Australian Foreign Acquisitions and Takeovers Act 1975, the Australian Competition and Consumer Act 2010, the United States Hart-Scott-Rodino Antitrust Improvements Act of 1976, and the Committee on Foreign Investment in the United States.

Next steps

A joint management information circular containing details of the transaction will be prepared and made available to securityholders of ATCO, Canadian Utilities and Emera in connection with the special meeting of each company’s securityholders expected to be held in early 2027.

Additional details regarding the transaction, including a copy of the arrangement agreement and the full text of the fairness opinions described in this press release, will be included in the circular. Securityholders are urged to read the circular, the arrangement agreement and other relevant documents when they become available, as they will contain important information about the transaction.
