TransAlta Corporation. (TransAlta€ or the €œCompany€) (TSX: TA) (NYSE: TAC) announced today that it has entered into an automatic share purchase plan (ASPP) with a broker in order to facilitate repurchases of TransAlta’s common shares (the €œCommon Shares) under its previously announced normal course issuer bid (NCIB).  

The Company previously announced that it had received approval from the Toronto Stock Exchange (TSX) to purchase up to 14,000,000 of its Common Shares, representing approximately 5.2% of the Company’s currently issued and outstanding Common Shares, during the 12-month period that commenced May 31, 2022 and terminates May 30, 2023. Purchases under the NCIB may be made through open market transactions on the TSX and any alternative Canadian trading platforms on which the Common Shares are traded, based on the prevailing market price. Since the beginning of the NCIB on May 31, 2022, the Corporation has purchased 5,518,000 Common Shares at a weighted average price per Common Share of $11.85 for an aggregate value of $65,401,768. Purchases under the current plan include 2,575,700 Common Shares purchased in 2023 at a weighted average price per Common Share of $11.18 for an aggregate value of $28,802,633.  

The Company believes that the prevailing price for the Common Shares may not, from time to time, reflect the underlying value of the Common Shares and that the purchase of Common Shares pursuant to the NCIB may be an attractive and appropriate use of available funds relative to other alternatives. The ASPP will facilitate purchases under the NCIB as it will allow for purchases of Common Shares to be made at times when the Company would ordinarily not be permitted to make purchases, whether due to regulatory restriction or customary self-imposed blackout periods. TransAlta is committed to enhancing shareholder returns through appropriate capital allocation such as a share buyback and its quarterly dividend, which are underpinned by the Company’s strong free cash flow position.

Under the ASPP, the Company’s broker may purchase Common Shares from the effective date of the ASPP until the end of the NCIB. The ASPP will facilitate purchases of Common Shares under the NCIB by authorizing the Company’s broker to make purchases at its sole discretion based on parameters set by the Company in accordance with TSX rules, applicable law and the terms of the ASPP. Outside of periods that the Company is restricted from purchasing Common Shares pursuant to insider trading rules or its own internal trading blackout policies, Common Shares may also be purchased based on management’s discretion, in compliance with TSX rules and applicable law. 

All purchases of Common Shares made under the ASPP will be included in determining the number of Common Shares purchased under the NCIB. Any Common Shares purchased by the Company pursuant to the NCIB will be cancelled. The Company is not currently restricted from purchasing Common Shares pursuant to any insider trading rules or its own internal trading blackout policies. The ASPP has been pre-cleared by the TSX and will be effective on or before April, 1, 2023.  

The ASPP will terminate on the earliest of the date on which: (a) the maximum purchase limits under the ASPP are reached; (ii) the NCIB expires; or (iii) the Company terminates the ASPP in accordance with its terms.

TransAlta Corporation (TransAlta or the Company) (TSX: TA) (NYSE: TAC) announced today its financial outlook for 2023.

Highlights

• Adjusted EBITDA⁽¹⁾ range of $1.20 billion to $1.32 billion
• Free Cash Flow⁽¹⁾⁽²⁾  range of $560 million to $660 million or FCF per share range of $2.07 to $2.44
• Sustaining capital⁽³⁾ range of $140 million to $170 million
• Continued delivery of TransAlta’s Clean Electricity Growth Plan by reaching final investment decision on 500 MW of additional clean energy projects across Alberta, the United States and Australia to deliver $75 million to $100 million of incremental adjusted EBITDA
• Appointment of Ms. Manjit Sharma to the Company’s Board of Directors effective Jan. 1, 2023

Strategy Update

• Continuing strong FCF supports TransAlta’s strategy of increasing shareholder value through significant capital allocation to contracted renewables growth
• Due to its strong financial position, TransAlta is positioned as the primary growth vehicle for the consolidated TransAlta group and expects to advance its Clean Electricity Growth Plan
• The Company will support organic expansions and opportunities to manage the current Canadian and Australian tax horizons of TransAlta Renewables Inc. (“TransAlta Renewables”), as well as  support the sustainability of the TransAlta Renewables’ dividend

€œWe are pleased to announce that our annual outlook highlights continuing strong cash flow expectations for 2023. Our fleet remains well positioned to capture the ongoing strength that we see in the Alberta merchant market. We are focused on redeploying these cash flows toward growing our contracted renewables asset base, which will create further value for our shareholders as we work to deliver our 2 GW renewables growth target by 2025,” said John Kousinioris, President and Chief Executive Officer of TransAlta.

€œAs we further advance our Clean Electricity Growth Plan and decarbonization efforts, TransAlta is well positioned to fully execute our growth plan.  As we move forward, we expect to prioritize new growth investments within the TransAlta parent company.  TransAlta Renewables will continue to retain growth opportunities where it has a right of first offer on organic expansions or where there is a mutual benefit to manage its tax horizon in order to sustain its current dividend, which is highly valued by its income-focused shareholders including TransAlta,€ added Mr. Kousinioris.

2023 Strategic Priorities

In addition to meeting the financial targets set out in the outlook, the Company is focused on the following key priorities for 2023:

• Advance customer-centred power solutions, renewables and storage, and grid reliability products for our Canadian, United States and Australian markets
• Continue execution of the Clean Electricity Growth Plan to deliver 2 GW of new generation and a 5 GW growth pipeline by 2025 by reaching final investment decision on 500 MW of additional clean energy projects across Canada, the United States and Australia
• Develop and maintain a growing pipeline of greenfield and brownfield development opportunities that add at least 1,500 MW of new development sites to our pipeline
• Achieve commercial operation and integration of the Garden Plain wind project, Northern Goldfields solar and storage project, White Rock and Horizon Hill wind projects and the Mount Keith transmission project ensuring these projects are delivered safely, on-time and on-budget consistent with their expected operating and financial performance expectations
• Complete the rehabilitation of Kent Hills targeting a safe return of the wind facility to full operations in the second half of 2023
• Advance a new technology roadmap that aligns with the Clean Electricity Growth Plan
• Advance long-term contractedness of the Alberta Electricity Portfolio through new and existing sales channels
• Deliver permanent financing for growth projects by executing tax equity or other financing program in order to monetize the value of production tax credits and other potential tax attributes

Update to Clean Electricity Growth Plan

To date, the Company has announced 800 MW of projects for a total cost of $1.5 billion toward our 2 GW Clean Electricity Growth Plan.  These projects are expected to deliver $147 million of annualized adjusted EBITDA.  With the current inflationary environment, we expect costs on future projects to be higher based on increases to expected pricing of equipment and construction labour. Although we estimate that the remaining projects will cost more, we see continuing demand for renewable energy and we expect PPA prices to respond to absorb these higher costs across the industry. As a result, we forecast that expected returns on projects will remain intact.  Accordingly, we have reset our capital investment target to $3.6 billion with an increased incremental EBITDA target of $315 million.

Clean Electricity Growth Plan Targets	Revised Target	Original  Target	Achieved to Date	% of Revised Target Achieved
Renewable Energy Capacity	2 GW	2 GW	800 MW	40%
Capital Investment	$3.6 billion	$3 billion	$1.5 billion	41%
Incremental EBITDA	$315 million	$250 million	$147 million	47%

Appointment of New Board Member

The Company is pleased to announce the appointment of Ms. Manjit Sharma to the Board of Directors effective January 1, 2023.  Ms. Sharma brings over 30 years of experience that spans a variety of industries, most recently serving as Chief Financial Officer of WSP Canada Inc.  In this role, she was responsible for leading the finance, real estate, procurement, tax and shared services functions across Canada.  Prior to WSP Canada Inc., she was on the National Executive Team of General Electric Canada (GE Canada), serving as Chief Financial Officer from 2016 to 2019. From 1999 to 2016, she held various senior positions with GE Canada, with responsibilities that spanned strategic planning and analysis, mergers and acquisitions, tax oversight, risk, governance, and diversity and inclusion. Ms. Sharma currently serves as a board member of each of Vermilion Energy Inc., Finning International Inc. and Export Development Canada.  She is also a member of the GE Canada Pension Trust Committee.

2023 Financial Outlook

Comparable EBITDA is estimated to be between $1.20 billion to $1.32 billion. The midpoint of the range represents continued strong performance compared to historical levels. The Company expects comparable EBITDA for 2023 to be impacted by a number of factors, including:

• Continued strong merchant pricing levels in Alberta though at a lowered target price range than 2022 based on our fundamental market forecast. The lower price expectations are driven by normalized weather expectations and the addition of new wind and solar supply including TransAlta’s Garden Plain wind facility, which is expected to achieve commercial operation in early 2023. This will be partially offset by lower fuel costs due to favourable natural gas hedges
• Adjusted EBITDA contributions from newly commissioned projects that include Garden Plain, White Rock, Horizon Hill, Northern Goldfields Solar and Mount Keith transmission asset additions
• Completion of the rehabilitation outage of Kent Hills 1 and 2 and fully returning the wind facility to service in the second half of 2023
• Adjusted performance expectations from the Energy Marketing segment due to exceptional performance achieved in 2022 partially driven by timing of cash settlements. The reversal of these settlements are included in our 2023 outlook.

The Company expects sustaining capital to be in the range of $140 million to $170 million consistent with current levels.

FCF is expected to be between $560 million and $660 million excluding the impact of rehabilitation capital expenditures required at Kent Hills. The midpoint of the range represents a 9 per cent increase over 2021 levels and a 19 per cent decrease from the midpoint of the 2022 outlook.  This is  largely driven by lower expected Alberta power pricing in 2023 and a return to normal performance from the Energy Marketing segment, both of which will be partially offset by the contribution from new assets.

The following table summarizes and provides additional details pertaining to our 2023 outlook:

Measure (millions)	2023 Target	2022 Target	2021 Actual
Adjusted EBITDA(1)	$1,200 and $1,320	$1,380 to $1,460	$1,263
FCF (1)	$560 and $660	$725 to $775	$562

Range of key power price assumptions:

Market	2023  Prices	2022  Prices
Alberta Spot ($/MWh)	$105 and $135	$125 to $150
Mid-C Spot ($/MWh)	US$75 to US$85	US$55 to US$65
AECO Gas Price ($/GJ)	$4.60	$5.00 to $6.00

Alberta spot price sensitivity: a +/- $1 per MWh change in spot price is expected to have a +/- $3.5 million annualized impact on Comparable EBITDA.

Other assumptions relevant to 2023 financial outlook (millions):

Sustaining capital(3)	$140 to $170
Energy marketing gross margin	$90 to $110

Alberta Hedging assumptions full year 2023:

Hedged production (GWh)	5,200
Hedge price ($/MWh)	$74.00
Hedged gas volumes (GJ)	58.4 million
Hedge gas price ($/GJ)	$2.24

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 Segmented Financial Performance and Operating Results section of the MD&A for further discussion of these items, including, where applicable, reconciliations to measures calculated in accordance with IFRS. See also the Additional IFRS Measures and Non-IFRS Measures section of this release.

(2) Free cash flow per share is calculated using the weighted average number of common shares outstanding. The weighted average number of common shares outstanding for the three and nine months ended Sept. 30, 2022 was 271 million shares. Please refer to the Non-IFRS financial measures section in this release for the purpose of this non-IFRS ratio.

(3) Excludes payments associated with finance leases and Kent Hills rehabilitation capital.

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 audited annual 2021 consolidated financial statements and the unaudited interim condensed consolidated statements of earnings (loss) for the three and nine months ended Sept. 30, 2022, 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, or as an alternative for, or more meaningful than our IFRS results.

Adjusted EBITDA

In the fourth quarter of 2021, comparable EBITDA was relabeled as adjusted EBITDA to align with industry standard terminology. 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 business profitability. In the second quarter of 2022, our adjusted EBITDA composition was adjusted to include the impact of closed positions that are effectively settled by offsetting positions with the same counterparty to reflect the performance of the assets and Energy Marketing segment in the period in which the transactions occur. 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. Adjusted EBITDA is a non-IFRS measure. Please refer to M39-M40 of the MD&A for a description of adjustments made.

Average Annual EBITDA

Average annual EBITDA is a non-IFRS financial measure that is forward-looking and is used to show the average annual EBITDA that the project currently under construction is expected to generate upon completion.

Funds From Operations

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 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 the 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 Financial Non-IFRS 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 a non-IFRS ratios.

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