TransAlta Reports First Quarter 2024 Results

CALGARY, Alberta, May 03, 2024 (GLOBE NEWSWIRE) --

TransAlta Corporation ("TransAlta" or the "Company") (TSX:TA) (NYSE:TAC) today reported its financial results for the first quarter ended March 31, 2024, demonstrating strong operational and financial performance and reaffirming its 2024 outlook.

First Quarter 2024 Financial Highlights

TransAlta's first quarter results exceeded our expectations given the anticipated decline in Alberta spot power prices to $99 per MWh in 2024, as compared to elevated spot power prices of $142 per MWh in 2023. The 30 per cent decline in spot prices year over year was primarily due to milder weather, lower natural gas prices and incremental generation from the addition of new wind and solar supply in the market. Highlights for the quarter include:

• Adjusted EBITDA⁽¹⁾ of $328 million, compared to $503 million for the same period in 2023
• Free Cash Flow ("FCF")⁽¹⁾ of $206 million or $0.67 per share, compared to $263 million or $0.98 per share for the same period in 2023
• Earnings before income taxes of $267 million, compared to $383 million for the same period in 2023
• Net earnings attributable to common shareholders of $222 million, compared to $294 million for the same period in 2023
• Cash flow from operating activities of $244 million, a decrease of $218 million for the same period in 2023
• The return of $53 million of capital to shareholders year to date through the buyback of 5.9 million common shares constituting 35 per cent of the Company's previously announced 2024 enhanced share repurchase program of up to $150 million

Other Business Highlights and Updates

• Achieved commercial operation of the 100 MW White Rock West wind facility on Jan. 1, 2024 and the 200 MW White Rock East wind facility on April 22, 2024
• Completed the Mount Keith 132kV expansion on Feb. 29, 2024
• Advanced commissioning of the 200 MW Horizon Hill wind facility to its final stages
• Achieved strong operational adjusted availability of 92.3 per cent
• Paused greenfield growth projects in Alberta pending clarity on the impact of new market regulations announced by the Government of Alberta
• Signed the 2024 Bow River Basin water sharing memorandum of understanding in preparation for potential lower water conditions in southern Alberta
• Announced the transition of its Executive Vice President, Finance and Chief Financial Officer ("CFO") with the retirement of Todd Stack effective June 30, 2024 and the appointment of Joel E. Hunter as Executive Vice President, Finance and CFO effective July 1, 2024
  
  

"Our first quarter results demonstrate the value of our asset optimization and hedging strategies, supported by our strong operating capabilities. We continue to perform well while managing through the evolving markets of our operating portfolio, illustrating the advantage of our diversified fleet," said Mr. John Kousinioris, President and Chief Executive Officer of TransAlta.

"We are confident that we will reach our 2024 guidance given the performance of our growing generating portfolio. We do not believe that our strong free cash flow results in the first quarter, and our expectations for the balance of 2024, are reflected in the current trading price of our common shares. As a result, we will continue to use share repurchases as part of our capital allocation strategy. Year to date, we have deployed $53 million towards share repurchases, which is approximately 35 per cent of our $150 million share repurchase target or $0.17 per share in value to shareholders," added Mr. Kousinioris.

"We are focused on making balanced capital allocation decisions that enhance value for our shareholders as we execute the next stage of our aspirational Clean Electricity Growth Plan. Given the recent announcements on market changes from the Government of Alberta, we have decided to pause greenfield development in Alberta until the full impact of the Restructured Energy Market is understood. Our focus will shift to our other core jurisdictions, the United States and Western Australia, where we will look to secure appropriate risk-adjusted returns within stable markets."

"The interim regulations to be adopted by the Government of Alberta effective July 1, 2024 in relation to market power mitigation and the supply cushion in the province remain in effect until Nov. 30, 2027 and are not expected to have a significant impact on our Company. We believe market prices and offer behaviour will be driven primarily by preexisting demand and supply fundamentals, which are already reflected in the weaker pricing conditions expected over the period of time that the regulations will be in place," added Mr. Kousinioris.

Key Business Developments

White Rock Wind Facilities Achieve Commercial Operation

On Jan. 1, 2024, the 100 MW White Rock West wind facility achieved commercial operation. On April 22, 2024, the 200 MW White Rock East wind facility was also commissioned. The White Rock wind facilities are located in Caddo County, Oklahoma and are contracted under two long-term PPAs with Amazon for the offtake of 100 per cent of the generation from the facilities. The Company's wind generating portfolio in the US now totals 819 MW in gross installed capacity.

Bow River Basin Memorandum of Understanding

On April 19, 2024, the Company announced it had signed a voluntary water-sharing memorandum of understanding with over thirty other water licence holders in the Bow River Basin. The Government of Alberta continues to anticipate and prepare for lower water conditions this summer with specific concerns in southern Alberta where agriculture could be impacted by water shortages. The Government of Alberta is leading efforts to coordinate water usage among water licence holders for Alberta river basins in an effort to ensure licensees get the water they need as opposed to the water to which they are entitled. In recognition of the unique role the Company plays in managing water flows while also serving as a key provider to Alberta's electricity grid, we look forward to working with the Government and downstream stakeholders to maximize water storage in the early season to help mitigate any anticipated drought conditions. We anticipate the Company's water management efforts will not have an adverse impact on our electricity generating and environmental objectives.

Annual Shareholder Meeting

The Honourable Rona Ambrose did not stand for reelection and retired from the Board of Directors ("Board") following the annual shareholder meeting on April 25, 2024. The Board extends its gratitude for her service to the Company. She has been a valuable contributor to the Board since 2017 and we thank her for her leadership and insight, including her contributions as Chair of the Governance, Safety and Sustainability Committee of the Board.

At the annual general meeting of the holders of common shares of TransAlta, the Company received strong support on all items of business, including the election of all 12 directors and Say on Pay.

TransAlta Announced Retirement of CFO and Appointment of New CFO

On April 11, 2024, the Company announced the retirement of Todd Stack, Executive Vice President, Finance and Chief Financial Officer from the Company, effective June 30, 2024. The Board expresses its deep appreciation to Mr. Stack for his contributions during his 34-year career with the Company. Mr. Joel E. Hunter will be appointed as Executive Vice President, Finance and CFO effective July 1, 2024.

Normal Course Issuer Bid ("NCIB") and Automatic Share Purchase Plan ("ASPP")

TransAlta is committed to enhancing shareholder returns through appropriate capital allocation such as share buybacks and its quarterly dividend. The Company previously announced an enhanced common share repurchase program for 2024 of up to $150 million, targeting up to 42 per cent of 2024 FCF guidance being returned to shareholders in the form of share repurchases and dividends.

The Company also previously announced that it had received approval from the Toronto Stock Exchange ("TSX") to purchase up to 14,000,000 of its common shares during the 12-month period that commenced on May 31, 2023 and will terminate on May 30, 2024. The Company intends to renew the NCIB in May 2024.

On March 19, 2024, the Company entered into an ASPP to facilitate repurchases of TransAlta's common shares under its NCIB.

Under the ASPP, the Company's broker may purchase common shares from the effective date of the ASPP until the termination of the ASPP. All purchases of common shares made under the ASPP will be included in determining the number of common shares purchased under the NCIB. The ASPP will terminate on the earliest of the date on which: (a) the maximum purchase limits under the ASPP are reached; (b) May 3, 2024; or (c) the Company terminates the ASPP in accordance with its terms.

During the three months ended March 31, 2024, the Company purchased and cancelled a total of 3,460,300 common shares, at an average price of $9.36 per common share, for a total cost of $32 million.

Mount Keith 132kV Expansion Complete

The Mount Keith 132kV expansion project was completed during the first quarter of 2024. The expansion was developed under the existing power purchase agreement with BHP Nickel West ("BHP"), which has a term of 15 years. The expansion will facilitate the connection of additional generating capacity to the transmission network which supports BHP's operations and increases its competitiveness as a supplier of low-carbon nickel.

Production Tax Credit ("PTC") Sale Agreements

On Feb. 22, 2024, the Company entered into a 10-year transfer agreement with an AA- rated customer for the sale of approximately 80 per cent of the expected PTCs to be generated from the White Rock and the Horizon Hill wind projects. The expected annual average EBITDA from these contracts is approximately $57 million (US$43 million).

First Quarter 2024 Financial Results Summary

For the three months ended March 31, 2024, the Company demonstrated strong financial and operational performance and is on track to meet its 2024 Outlook, due to active management of our merchant portfolio and hedging strategies, which included higher production in the Hydro and Gas segments.

Production for the renewables fleet for the three months ended March 31, 2024, was 1,849 GWh compared to 1,503 GWh for the same period in 2023, an increase of 346 GWh or 23 per cent, primarily due to:

• Production from new facilities, including the White Rock West wind facility commissioned in January 2024 and the Garden Plain wind facility commissioned in August 2023;
• The return to service of the Kent Hills wind facilities, completed in the first quarter of 2024;
• Precommissioning production from the White Rock East wind facility and the Horizon Hill wind project, partially offset by lower wind resource in Alberta; and
• Higher hydro production due to significant demand resulting from periods of extreme cold conditions in Alberta.

Total production for the three months ended March 31, 2024, was 6,178 GWh compared to 5,972 GWh for the same period in 2023, an increase of 206 GWh or 3 per cent, primarily due to:

• Higher production of 356 GWh or 11 per cent from the gas segment driven primarily by the Sarnia facility as market conditions were favourable, which enabled higher dispatch resulting in higher merchant production to the Ontario grid;
• Higher production from our renewables fleet discussed above; partially offset by
• Negatively impacted production of 801 GWh, a decrease of 496 GWh or 38 per cent, from the Energy Transition segment compared to the same period in 2023, primarily due to higher unplanned outage hours and increased economic dispatch at the Centralia facility.
  
  

Adjusted availability for the three months ended March 31, 2024, was 92.3 per cent, compared to 92.0 per cent in the same period in 2023, an increase of 0.3 per cent, primarily due to:

• The return to service of the Kent Hills wind facilities;
• Lower unplanned outages in the Wind and Solar segment, partially offset by;
• Unplanned outages at Centralia Unit 2 in the Energy Transition segment;
• Unplanned outages at Sundance Unit 6 and the Australia gas facilities; and
• Planned major maintenance outages in the Hydro segment.
  
  

Adjusted EBITDA for the three months ended March 31, 2024, was $328 million compared to $503 million in 2023, a decrease of $175 million, or 35 per cent. Although overall results were in line with expectations for the year, the major factors impacting adjusted EBITDA compared to the same period of 2023 are summarized below:

• Hydro adjusted EBITDA decreased by $19 million, or 18 per cent, compared to the same period in 2023, primarily due to lower realized gains on forward contracts and lower realized power and ancillary services prices in the Alberta market, partially offset by higher production due to significant demand in periods of extreme cold temperature conditions in Alberta, and higher sales of environmental attributes to third parties;
• Wind and Solar adjusted EBITDA increased by $1 million, or 1 per cent, compared to the same period in 2023 primarily due to higher environmental attribute revenues, higher production from the return to service of the Kent Hills wind facilities, the commercial operation of the Garden Plain and White Rock West wind facilities and the Northern Goldfields solar facilities, partially offset by lower realized power prices in Alberta and weaker wind resource across the Alberta operating fleet;
• Gas adjusted EBITDA decreased by $106 million, or 44 per cent, compared to the same period in 2023, primarily due to lower realized power and ancillary prices from the Alberta merchant fleet driven by lower spot prices and the impact of lower-priced hedge contracts, lower capacity payments in 2024 for Southern Cross Energy in Australia due to the scheduled conclusion on Dec. 31, 2023 of the demand capacity charge under the applicable contract, higher fuel and purchased power from higher production, increased carbon costs and higher OM&A expenses mainly due to increased salary escalations, partially offset by the commencement in March 2024 of capacity payments from the Mount Keith 132kV expansion and lower natural gas commodity costs;
• Energy Transition adjusted EBITDA decreased by $28 million, or 52 per cent, compared to 2023, primarily due to lower production from higher unplanned outages at Centralia Unit 2 and increased economic dispatch due to lower market prices, partially offset by lower fuel costs from lower production volumes;
• Energy Marketing adjusted EBITDA decreased by $19 million, or 49 per cent, compared to the same period in 2023, but is in line with management expectations primarily due to lower realized settled trades in the first quarter of 2024 on market positions in comparison to the prior period, partially offset by lower OM&A due to lower incentives; and
• Corporate adjusted EBITDA decreased by $4 million, or 17 per cent, compared to the same period in 2023, primarily due to increased spending to support strategic and growth initiatives.

Cash flow from operating activities totalled $244 million for the three months ended March 31, 2024, compared to $462 million in the same period in 2023, a decrease of $218 million, or 47 per cent, primarily due to:

• Lower gross margin on lower revenues and higher carbon compliance costs;
• Lower current income tax expense due to decrease in earnings before tax; and
• Lower accounts payable and accrued liabilities and higher collateral provided as a result of market price volatility, partially offset by lower accounts receivable from lower revenues and higher collateral received related to derivative instruments.
  
  

Free Cash Flow totalled $206 million for the three months ended March 31, 2024, compared to $263 million for the same period in 2023, a decrease of $57 million, or 22 per cent. The major factors impacting free cash flow were:

• Lower adjusted EBITDA items as noted above;
• Lower current income tax expense due to lower earnings before tax;
• Lower sustaining capital expenditures due to the receipt of a lease incentive related to the relocation of the Company's head office; and
• Lower distributions paid to subsidiaries' non-controlling interests relating to the timing of distributions paid to TA Cogen and the cessation of distributions by TransAlta Renewables Inc. resulting in higher free cash flow.

Net earnings attributable to common shareholders totalled $222 million for the three months ended March 31, 2024, compared to $294 million in the same period in 2023, a decrease of $72 million, primarily due to:

• Lower adjusted EBITDA due to items discussed above; and
• Fluctuations in current and deferred tax expense with earnings before tax across the quarters.

Alberta Electricity Portfolio

The average spot power price per MWh for the three months ended March 31, 2024 was above the upper end of guidance but decreased from $142 per MWh in 2023 to $99 per MWh in 2024 primarily due to:

• Milder weather compared to the same period in 2023;
• Lower natural gas prices; and
• Higher generation from the additions of new wind and solar supply in the market compared to the prior period.
  
  

Gross margin for the three months ended March 31, 2024, was $231 million, a decrease of $118 million, compared to the same period in 2023. The decrease was primarily due to:

• The impacts of lower Alberta realized spot prices and lower fixed-price hedges; partially offset by
• Higher environmental attribute revenues.

Hedged volumes for the three months ended March 31, 2024, were 1,908 GWh at an average price of $88 per MWh compared to 2,046 GWh at an average price of $136 per MWh in 2023. Hedged production volumes for the three months ended March 31, 2024, decreased compared to the same period in 2023, primarily from fewer strategic hedges executed for the first quarter of 2024.

Liquidity and Financial Position

We expect to maintain adequate available liquidity under our committed credit facilities. As at March 31, 2024, we had access to $1.7 billion in liquidity, including $417 million in cash.

Notes

(1) These items are not defined and have no standardized meaning under IFRS. Presenting these items from period to period provides management and investors with the ability to evaluate earnings (loss) trends more readily in comparison with prior periods' results. Please refer to the Non-IFRS Measures section of this earnings release for further discussion of these items, including, where applicable, reconciliations to measures calculated in accordance with IFRS.

(2) Funds from operations ("FFO") per share and free cash flow ("FCF") per share are calculated using the weighted average number of common shares outstanding during the period. Refer to the Additional IFRS Measures and Non-IFRS Measures section of the MD&A for the purpose of these non-‍IFRS ratios.

Non-IFRS financial measures and other specified financial measures

We use a number of financial measures to evaluate our performance and the performance of our business segments, including measures and ratios that are presented on a non-IFRS basis, as described below. Unless otherwise indicated, all amounts are in Canadian dollars and have been derived from our unaudited interim condensed consolidated financial statements prepared in accordance with IFRS. We believe that these non-IFRS amounts, measures and ratios, read together with our IFRS amounts, provide readers with a better understanding of how management assesses results.

Non-IFRS amounts, measures and ratios do not have standardized meanings under IFRS. They are 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.

Adjusted EBITDA

Each business segment assumes responsibility for its operating results measured by adjusted EBITDA. Adjusted EBITDA is an important metric for management that represents our core operational results. Interest, taxes, depreciation and amortization are not included, as differences in accounting treatments may distort our core business results. In addition, certain reclassifications and adjustments are made to better assess results, excluding those items that may not be reflective of ongoing business performance. This presentation may facilitate the readers' analysis of trends.

Funds From Operations ("FFO")

FFO is an important metric as it provides a proxy for cash generated from operating activities before changes in working capital and provides the ability to evaluate cash flow trends in comparison with results from prior periods. FFO is a non-IFRS measure.

Free Cash Flow ("FCF")

FCF is an important metric as it represents the amount of cash that is available to invest in growth initiatives, make scheduled principal repayments on debt, repay maturing debt, pay common share dividends or repurchase common shares. Changes in working capital are excluded so FFO and FCF are not distorted by changes that we consider temporary in nature, reflecting, among other things, the impact of seasonal factors and timing of receipts and payments. FCF is a non-IFRS measure.

Non-IFRS Ratios

FFO per share, FCF per share and adjusted net debt to adjusted EBITDA are non-IFRS ratios that are presented in the MD&A. Refer to the Reconciliation of Cash Flow from Operations to FFO and FCF and Key Non-IFRS Financial Ratios sections of the MD&A for additional information.

FFO per share and FCF per share

FFO per share and FCF per share are calculated using the weighted average number of common shares outstanding during the period. FFO per share and FCF per share are non-IFRS ratios.

Reconciliation of these non-IFRS financial measures to the most comparable IFRS measure are provided below.
