TransAlta to Acquire Heartland Generation from Energy Capital Partners at a Reduced Price of $542 Million

Highlights

• TransAlta and ECP have agreed to an $80 million purchase price reduction to reflect two required asset divestitures representing 97 MW (net ownership)
• Transaction revalued at approximately $542 million, inclusive of the assumption of $232 million of low-cost debt, and subject to a further favourable economic adjustment of approximately $80 million, reflecting the economic benefit of the Heartland business arising since the effective date of the transaction of October 31, 2023, prior to working capital adjustments
• Heartland portfolio valued at a net price of approximately $270 per kilowatt, with an expected EBITDA multiple¹ of approximately 5.4 times
• Highly accretive to free cash flow, with an attractive cash yield upon closing underpinned by approximately 60% of revenues contracted with a weighted-average remaining life of 15 years
• Corporate pre-tax synergies of approximately $20 million per annum
• Transaction to add 1,747 MW (net interest) of complementary capacity, including contracted cogeneration and peaking generation, legacy gas-fired thermal generation, transmission capacity, and potential hydrogen development opportunities, all of which will be critical to support reliability in the Alberta electricity market
• Enhances and further diversifies TransAlta’s competitive portfolio in the highly dynamic and shifting electricity landscape in Alberta

TransAlta Corporation (TSX: TA; NYSE: TAC) (“TransAlta” or “Company”) announced today that it has entered into an amending agreement to the share purchase agreement (the “Amending Agreement”) with an affiliate of Energy Capital Partners (“ECP”), the parent of Heartland Generation Ltd. and Alberta Power (2000) Ltd. (collectively, “Heartland”), relating to the previously announced acquisition of Heartland and its business operations by TransAlta (the “Transaction”). In order to meet the requirements of the federal Competition Bureau (“Bureau”), TransAlta has also entered into a consent agreement with the Commissioner of Competition pursuant to which TransAlta has agreed to divest Heartland’s Poplar Hill and Rainbow Lake assets following closing of the Transaction (the “Divestitures”). Closing of the Transaction is expected to occur on or before December 4, 2024.

In consideration of the Divestitures, TransAlta and ECP have agreed to a purchase price reduction of $80 million for the Transaction. ECP will be entitled to receive the proceeds from the sale of Poplar Hill and Rainbow Lake, net of certain adjustments following completion of the Divestitures. The revised transaction price of $542 million will be further reduced by approximately $80 million following closing of the Transaction, to reflect the economic benefit of the Heartland business arising since October 31, 2023, which is payable to TransAlta, consistent with the terms of the original share purchase agreement. The net cash payment for the Transaction, before working capital adjustments, is estimated at $230 million, and will be funded through a combination of cash on hand and draws on its credit facilities.

“We are pleased to be able to move forward with the Heartland acquisition in the coming weeks, and to incorporate Heartland’s complementary assets within our Alberta portfolio. Consistent with our original investment thesis, the Alberta market will increasingly require low-cost, flexible and fast-responding generation to support grid reliability over the coming years. The transaction supports our competitive position in Alberta by ensuring we maintain a robust and diversified portfolio, which together with our energy marketing capabilities, complements and supports Alberta’s electricity grid. The Heartland portfolio will contribute meaningful cash flows with significant value from our corporate synergies, even with the planned asset divestitures,” said John Kousinioris, President and Chief Executive Officer of TransAlta.

Heartland owns and operates generation assets consisting of 507 MW of cogeneration, 387 MW of contracted and merchant peaking generation, 950 MW of natural gas-fired thermal generation, transmission capacity and a development pipeline that includes the 400 MW Battle River Carbon Hub.

Investment Highlights

The transaction is strategically attractive to TransAlta and provides the following benefits:

• Expands Flexible Generation Capabilities: Augments and diversifies TransAlta’s portfolio in Alberta’s current energy-only market by expanding its flexible, fast-ramping capacity and marketing capabilities to enhance our ability to respond to changing market conditions stemming from the intermittency of increasing renewable generation.
• Maintains Attractive Transaction Metrics: The acquisition is highly accretive to free cash flow with an attractive multiple and strong cash yield. The Transaction, net of economic adjustment, values the portfolio of assets at approximately $270 per kilowatt, well below the replacement cost of current and other forms of reliable generation, providing a low-cost expansion of our ability to deliver reliable generation to the market demands of Alberta.
• Delivers Highly Contracted Cash Flow: Post-closing, the assets are expected to add approximately $85 to $90 million of average annual EBITDA² after factoring synergies and the divestitures of Poplar Hill and Rainbow Lake. Approximately 60 per cent of revenues are under contract with high creditworthy counterparties which have a weighted-average remaining contract life of 15 years.
• Near-term Synergies: TransAlta will continue to leverage corporate costs within our existing business which will provide estimated corporate pre-tax synergies of approximately $20 million per annum. In addition, the combined portfolio will enable the Company to further optimize operations and supply chains through scale to achieve additional synergies.
• Builds On Regional Expertise: The Company is well positioned to deliver significant value through our deep technical and local operational experience which, together with our 113-year history in Alberta, will ensure continuing safe and reliable generation in a dynamic and evolving landscape.

¹ Expected EBITDA multiple is a metric calculated by dividing expected capital expenditures by average annual EBITDA. Readers are cautioned that our method for calculating expected EBITDA multiple may differ from methods used by other entities. Therefore, it may not be comparable to similar measures presented by other entities.

² Average annual EBITDA is not defined and has no standardized meaning under IFRS. It is a forward-looking non-IFRS measure that is used to show the average annual adjusted EBITDA that is expected to generate following completion of the Transaction. It is unlikely to be comparable to similar measures presented by other companies and should not be viewed in isolation from, as an alternative to, or more meaningful than, our IFRS results. Please refer to the “Additional IFRS Measures and Non-IFRS Measures” section of our management’s discussion and analysis for the three and nine months ended September 30, 2024 (“MD&A”) for more information about the non-IFRS measures we use, including a reconciliation of adjusted EBITDA to Earnings before income tax, the most directly comparable IFRS measure, which section of the MD&A is incorporated by reference herein.
