MARTINREA INTERNATIONAL INC. ANNOUNCES TSX APPROVAL OF NORMAL COURSE ISSUER BID

Martinrea International Inc. has filed with the Toronto Stock Exchange, and the TSX has accepted, its notice of intention to make a normal course issuer bid. Pursuant to the NCIB, Martinrea is entitled to purchase for cancellation up to 6,874,272 common shares over a 12-month period, representing approximately 10 per cent of the public float.

The NCIB will commence on May 27, 2026, and terminate on May 26, 2027, or such earlier date on which purchases under the NCIB have been completed. Purchases of shares under the NCIB will be made through the facilities of the TSX and/or alternative Canadian trading systems at the market price of the shares at the time of acquisition. The average daily trading volume of the shares on the TSX for the past six months is 93,575 shares. The maximum number of shares that may be purchased on a daily basis, subject to any approved exceptions, will be 23,393 shares. Shares purchased under the NCIB will be cancelled.

During the past 12 months, Martinrea was authorized to repurchase up to 7,110,571 shares under a normal course issuer bid, which commenced on May 27, 2025, and will terminate on May 26, 2026. As of May 15, 2026, Martinrea purchased 2,301,507 shares for cancellation under the prior bid at a weighted-average price of approximately $10.03. The prior bid purchases were made on the open market through the facilities of the TSX and/or alternative Canadian trading systems.

The company believes that the shares may from time to time trade in a price range that does not adequately reflect the value of the shares in relation to the company's activities and future prospects. As a result, the company believes that the purchase of shares, from time to time, would be an appropriate use of corporate funds in light of potential benefits to remaining shareholders.
