CALGARY, Alberta, Nov. 05, 2024 (GLOBE NEWSWIRE) --

TransAlta Corporation ("TransAlta" or the "Company") (TSX:TA) (NYSE:TAC) today reported its financial results for the three and nine months ended Sept. 30, 2024, demonstrating another quarter of strong financial performance.

"Our third quarter results illustrate the value of our proactive hedging strategy together with the active management of our Alberta merchant portfolio. Our asset optimization strategies have achieved exceptional results and we are tracking toward the upper end of our 2024 guidance given our portfolio position and performance during the first nine months of the year," said John Kousinioris, President and Chief Executive Officer of TransAlta.

"As we look forward, given the ample supply conditions for Alberta throughout 2025, we have taken the decision to temporarily mothball Sundance 6, holding it in reserve as we continue to explore future economic opportunities relating to new demand for electricity entering the province and the enhancement of grid reliability. We will maintain flexibility to returning Sundance 6 to service as market fundamentals improve or opportunities to contract are secured."

"Finally, we remain actively engaged in commercial discussions with Energy Capital Partners in respect of the acquisition of Heartland Generation and are making progress with the Competition Bureau in our effort to obtain regulatory approval. We are optimistic that we have a pathway to completing the transaction and adding Heartland's complementary assets to our portfolio. We are also pursuing multiple opportunities to support the energy transition in our core jurisdictions, while at the same time actively pursuing redevelopment and recontracting opportunities at our increasingly valuable legacy thermal fleet," added Mr. Kousinioris.

Third Quarter 2024 Financial Highlights

TransAlta's third quarter results exceeded expectations delivering strong free cash flow and exceptional operating performance. The Company delivered Free Cash Flow ("FCF") per share⁽¹⁾ of $0.47, due to its proactive hedging and asset management strategies given the anticipated decline in Alberta spot power prices in 2024, milder than anticipated weather, low natural gas prices and incremental generation from new supply in the market. Highlights for the quarter include:

Adjusted EBITDA⁽¹⁾ of $325 million, compared to $453 million for the same period in 2023
Operational adjusted availability of 94.5 per cent, compared to 91.9 per cent for the same period in 2023
FCF⁽¹⁾of $140 million or $0.47 per share, compared to $228 million or $0.87 per share for the same period in 2023
The return of $114 million of capital to shareholders during the nine months ended Sept. 30, 2024, through the buyback of 11.8 million common shares constituting 76 per cent of the Company's 2024 enhanced share repurchase program of up to $150 million
Tracking towards the upper end of guidance for 2024 of
- Adjusted EBITDA of $1,150 million to $1,300 million
- FCF of $450 million to $600 million

Other Business Highlights and Updates

Advancing the acquisition of Heartland Generation.
Temporarily mothballing Sundance Unit 6 effective April 1, 2025 for a period of up to two years.

Key Business Developments

Third Quarter 2024 Financial Results Summary

Production for the three months ended Sept. 30, 2024, was 5,712 GWh compared to 5,678 GWh, an increase of one per cent, compared to the same period in 2023, primarily due to:

Higher production from the Wind and Solar segment, driven primarily by new asset additions, including White Rock, Horizon Hill and Northern Goldfields, together with the return to service of the Kent Hills; partially offset by
Lower production from the Gas segment, primarily due to higher dispatch optimization and lower market prices in Alberta;
Lower production from the Energy Transition segment, which was impacted by increased economic dispatch at the Centralia facility due to lower market prices; and
Lower production from the Hydro segment due to lower water resources and increased planned outages.

Adjusted availability for the three months ended Sept. 30, 2024, was 94.5 per cent, an increase of 2.6 percentage points, compared to the same period in 2023, primarily due to:

The addition of the newly commissioned Oklahoma wind and Western Australia solar assets; and
The return to service of the Kent Hills wind facilities; partially offset by
Higher planned major maintenance outages and unplanned outages in the Hydro segment.

Adjusted EBITDA for the three months ended Sept. 30, 2024, was $325 million, a decrease of $128 million, or 28 per cent, compared to the same period in 2023. The major factors impacting adjusted EBITDA are summarized below:

Hydro adjusted EBITDA for the three months ended Sept. 30, 2024, decreased by $61 million, or 41 per cent, compared to the same period in 2023, although broadly in line with expectations, primarily due to:
- Lower power prices in the Alberta market; and
- Lower energy production due to lower water resources in the North Saskatchewan River region and increased planned outages across our fleet compared to the same periods in 2023; partially offset by
- Higher ancillary services volumes due to increased demand by the AESO;
- Realized premiums over spot prices stemming from asset optimization activities; and
- Higher environmental and tax attributes revenues due to the increased sales of emission credits to third parties and intercompany sales to the Gas segment.
Wind and Solar adjusted EBITDA for the three months ended Sept. 30, 2024, increased by $7 million, or 19 per cent, compared to the same period in 2023, primarily due to:
- The addition of the Oklahoma wind assets, including tax attribute revenue from the transfer of production tax credits (PTC) to taxable US counterparties; and
- Higher production from the return to service of the Kent Hills wind facilities; partially offset by
- Lower realized power prices at our merchant assets in the Alberta market.
Gas adjusted EBITDA for the three months ended Sept. 30, 2024, decreased by $115 million, or 45 per cent, compared to the same period in 2023, although results were broadly in line with expectations. The decrease was primarily due to:
- Lower production from the Alberta gas fleet where excess supply conditions in the market drove higher dispatch optimization and lower realized prices, which were partially mitigated by our higher volume of hedges which had favourable premiums to spot merchant prices; and
- Lower capacity payments at Southern Cross Energy in Australia due to the scheduled conclusion on Dec. 31, 2023, of the demand capacity charge under the customer contract, partially offset by the commencement in March 2024 of capacity payments for the Mount Keith 132kV expansion.
Energy Transition adjusted EBITDA for the three months ended Sept. 30, 2024, increased by $5 million, or 17 per cent, compared to the same period in 2023, primarily due to:
- Lower purchased power costs driven by lower Mid-C prices on repurchases of power and lower production; partially offset by
- Increased economic dispatch due to lower market prices driving lower production.
Energy Marketing adjusted EBITDA for the three months ended Sept. 30, 2024, increased by $41 million, or 315 per cent, compared to the same period in 2023, primarily due to favourable market volatility across North American power and natural gas markets and higher realized settled trades in the third quarter of 2024 in comparison to the prior period.
Corporate adjusted EBITDA for the three months ended Sept. 30, 2024, decreased by $5 million or 17 per cent, compared to the same period in 2023, primarily due to increased spending for the planning and design of the enterprise resource planning ("ERP") upgrade program, and to support strategic and growth initiatives.

Net loss attributable to common shareholders for the three months ended Sept. 30, 2024, totalled $36 million, compared to net earnings attributable to common shareholders of $372 million for the same period in 2023, primarily due to:

Lower adjusted EBITDA due to the items discussed above;
Lower unrealized mark-to-market gains in the Gas segment was due to the prior period having significant volume of favourable hedging positions relating to the Alberta portfolio which largely have settled;
Higher unrealized mark-to-market losses in the Wind and Solar segment was mainly due to the long-term wind energy sales related to the Oklahoma projects in the Central US. The unrealized losses were due to the strengthening forecasted wind capture prices reflected in the period;
Lower unrealized mark-to-market gains in the Energy Marketing segment is mainly driven by market volatility across North American power and natural gas markets; and
Higher asset impairment charges resulting from changes in decommissioning and restoration provisions related to discount rates and revision in estimated costs to decommission retired assets; partially offset by
Lower depreciation and amortization primarily due to revisions to useful lives on certain facilities in prior periods.

Excluding unrealized mark-to-market losses and gains, net earnings attributable to common shareholders for the three months ended Sept. 30, 2024, was $23 million, or $0.08 per share⁴ compared to $202 million, or $0.68 per share⁴, for the same period in 2023.

FCF for the three months ended Sept. 30, 2024, totalled $140 million, a decrease of $88 million, or 39 per cent, compared to the same period in 2023, primarily due to:

Lower adjusted EBITDA items as noted above;
Higher current income tax expense due to the full utilization of Canadian non-capital loss carryforwards in 2023, partially offset by lower earnings before income taxes for the period; and
Higher net interest expense³ due to lower capitalized interest driven by completion of the construction program previously underway and lower interest income resulting from lower cash balances; partially offset by
Lower distributions paid to subsidiaries' non-controlling interests relating to lower TransAlta Cogeneration, LP net earnings resulting from lower merchant pricing in the Alberta market and the cessation of distributions to TransAlta Renewables Inc. non-controlling interest. On Oct. 5, 2023, the Company acquired all of the outstanding common shares of TransAlta Renewables not already owned, directly or indirectly.

Cash from operating activities for the three months ended Sept. 30, 2024, of $229 million decreased by $452 million, or 66 per cent, compared to the same period in 2023, primarily due to:

Lower revenues net of unrealized losses from risk management activities; and
Higher trade and other receivables resulting in an unfavourable change in non-cash operating working capital balances; partially offset by
Lower fuel and purchased power.

Alberta Electricity Portfolio

The average spot power price per MWh for the three months ended Sept. 30, 2024, decreased to $55 per MWh from $152 per MWh in the same period in 2023, primarily due to:

Higher generation from the addition of new wind, solar and gas supply in the Alberta merchant market compared to the prior period;
Lower natural gas prices; and
Lower volatility due to milder weather compared to the same period in 2023.

The realized merchant power price per MWh of production for the three months ended Sept. 30, 2024, decreased to $90 MWh from $140 MWh, compared to the same period in 2023, although was significantly higher than average spot power prices during the quarter, primarily due to:

Lower average spot power prices as explained above; and
Lower hedge prices compared to the same period in 2023.

Carbon compliance cost per MWh of production for the three months ended Sept. 30, 2024, increased to $19 per MWh from $13 per MWh, compared to the same period in 2023, primarily due to an increase in carbon pricing from $65 per tonne to $80 per tonne.

Hedged volumes for the three months ended Sept. 30, 2024, were 2,365 GWh at an average price of $85 per MWh. Volumes increased over the same period in 2023 by 246 GWh, with realized gains and losses on financial hedges included in Revenues.

Liquidity and Financial Position

We expect to maintain adequate available liquidity under our committed credit facilities. As at Sept. 30, 2024, we had access to $1.8 billion in liquidity, including $401 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.

(3) Net interest expense includes interest expense for the period less interest income.

(4) Calculated using the weighted average number of common shares outstanding for the three months ended Sept. 30, 2024.

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. In the second quarter of 2024, our reported EBITDA composition was adjusted to include the impact of acquisition transaction and integration costs as the Company does not have frequent business acquisitions and the acquisition transaction and integration costs are not reflective of Company's ongoing business performance. Accordingly, the Company has applied this composition to all previously reported periods. 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.
