TransAlta Announces Supplemental Changes to Stock Option Plan

CALGARY, April 3, 2020 /PRNewswire/ - TransAlta Corporation ("TransAlta" or the "Company") (TSX: TA) (NYSE: TAC) today announced that it has adopted certain changes to its Stock Option Plan.

In TransAlta's management information circular dated March 9, 2020 (the "Information Circular") for its upcoming annual and special meeting of shareholders scheduled to be held on April 21, 2020 (the "Meeting"), the Company disclosed that it is seeking approval by its shareholders at the Meeting to amend its Stock Option Plan solely to increase the number of shares available for issuance pursuant to options granted under the Stock Option Plan. In the meantime, in order to align features of the Stock Option Plan with current best governance and market practices, the Company has adopted certain changes to the Stock Option Plan's amendment provisions to further limit the Board of Director's ability to make amendments without shareholder approval in the future. As a result of these changes, the amendment provisions in the Stock Option Plan require that majority shareholder approval be obtained for any changes to the Stock Option Plan (in addition to those enumerated items already requiring shareholder approval) that would: (i) reduce the exercise price of (or any cancellation and re-grant of an option that would reduce the exercise price of) options or other entitlements held by non-insiders; (ii) extend the term of options held by non-insiders beyond their original expiry date; (iii) expand the Stock Option Plan's eligibility criteria or participation limits (including amendments to the definition of "participant") applicable to non-employee directors; and (iv) permit options to be transferred or assigned other than for normal estate settlement purposes. At the Meeting, shareholders will still be asked to approve an ordinary resolution to increase the number of shares available for issuance under the Stock Option Plan, as described in the Information Circular. TransAlta's Board of Directors continues to unanimously recommend that shareholders vote "FOR" the increased allocation under the Stock Option Plan, which will only become effective if approved by shareholders at the Meeting.

A copy of the updated Stock Option Plan, which reflects the changes described above, will be available under our profile on SEDAR at www.sedar.com and on EDGAR at www.sec.gov. Further details in respect of the Meeting are available in the Information Circular and related proxy materials, which can be found under our profile on SEDAR at www.sedar.com and on EDGAR at www.sec.gov.
