<P STYLE="font: bold 24pt Arial, Helvetica, Sans-Serif; margin-right: 0; margin-left: 0">TransAlta Announces TSX Acceptance of Normal
Course Issuer Bid</P>

<P STYLE="font: 15pt Arial, Helvetica, Sans-Serif; margin-right: 0; margin-left: 0">CALGARY, AB, May 25, 2021 /CNW/ -&nbsp;TransAlta Corporation
(&quot;TransAlta&quot; or the &quot;Company&quot;) (TSX: TA) (NYSE: TAC) today announced that the Toronto Stock Exchange (&quot;TSX&quot;)
has accepted the notice filed by the Company to implement a normal course issuer bid (&quot;NCIB&quot;) for a portion of its common shares
(&quot;Common Shares&quot;).&nbsp;</P>

<P STYLE="font: 15pt Arial, Helvetica, Sans-Serif; margin-right: 0; margin-left: 0">Pursuant to the NCIB, TransAlta may repurchase up
to a maximum of 14,000,000 Common Shares, representing approximately 7.16% of its public float of Common Shares as at May 18, 2021. 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.&nbsp;Any Common Shares purchased under the NCIB will be cancelled.</P>

<P STYLE="font: 15pt Arial, Helvetica, Sans-Serif; margin-right: 0; margin-left: 0">Transactions under the NCIB will depend on future
market conditions. TransAlta will initially retain discretion whether to make purchases under the NCIB, and to determine the timing, amount
and acceptable price of any such purchases, subject at all times to applicable TSX and other regulatory requirements. The period during
which TransAlta is authorized to make purchases under the NCIB commences on May 31, 2021 and ends on May 30, 2022 or such earlier date
on which the maximum number of Common Shares are purchased under the NCIB or the NCIB is terminated at the Company's election.&nbsp;&nbsp;</P>

<P STYLE="font: 15pt Arial, Helvetica, Sans-Serif; margin-right: 0; margin-left: 0">Under TSX rules, not more than 169,737 Common Shares
(being 25% of the average daily trading volume on the TSX of 678,948&nbsp;Common Shares for the six months ended April 30, 2021) can be
purchased on the TSX on any single trading day under the NCIB, with the exception that one block purchase in excess of the daily maximum
is permitted per calendar week. As at May 18, 2021, there were 269,883,087&nbsp;Common Shares issued and outstanding.</P>

<P STYLE="font: 15pt Arial, Helvetica, Sans-Serif; margin-right: 0; margin-left: 0">TransAlta has repurchased and cancelled 6,055,600&nbsp;Common
Shares on the open market through the facilities of the TSX and/or alternative Canadian trading platforms at an average price of $8.664
per share under its prior NCIB approved by the TSX on May 26, 2020 for the twelve-month period commencing May 29, 2020.</P>

<P STYLE="font: 15pt Arial, Helvetica, Sans-Serif; margin-right: 0; margin-left: 0">The NCIB provides the Company with a capital allocation
alternative with a view to long-term shareholder value. TransAlta's Board of Directors and Management believe that, from time to time,
the market price of the Common Shares does not reflect their underlying value and purchases of Common Shares for cancellation under the
NCIB may provide an opportunity to enhance shareholder value.</P>
