SECURE ANNOUNCES FINAL RESULTS OF ITS SUBSTANTIAL ISSUER BID

CALGARY, AB , May 20, 2025 /CNW/ - SECURE Waste Infrastructure Corp. ("SECURE") (TSX: SES) announced today the final results of its previously announced substantial issuer bid which expired on May 14, 2025 (the "Offer"). In accordance with the terms and conditions of the Offer and based on the final count by Odyssey Trust Company, as depositary for the Offer (the "Depositary"), SECURE has taken up and will pay for 9,382,390 Shares at a purchase price of $14.50 per Share.

The Shares to be purchased under the Offer represent an aggregate purchase price of $136,044,655 and approximately 4% of SECURE's issued and outstanding Shares before giving effect to the Offer. After the cancellation of Shares taken up and paid for by SECURE, SECURE anticipates that 221,492,148 Shares will be issued and outstanding.

Payment and settlement of the Shares purchased pursuant to the Offer will be effected by the Depositary in accordance with the settlement procedures described in the Offer Documents (as defined below) and applicable law. Any Shares not purchased under the Offer from Shareholders making a proportionate tender will be returned to the respective Shareholders as soon as practicable by the Depositary.

For Canadian federal income tax purposes, a dividend is deemed to be paid on the repurchase of Shares under the Offer. To assist Shareholders in determining the Canadian income tax consequences of the Offer, SECURE has determined that for purposes of the Income Tax Act (Canada) (the "Tax Act"), the paid-up capital per Share is estimated to be approximately $4.95 at the time of repurchase under the Offer. Shareholders should review the issuer bid circular dated April 7, 2025 (the "Circular") for more information, including information about the Canadian federal income tax treatment of deemed dividends (refer to Section 13 "Income Tax Considerations – Certain Canadian Federal Income Tax Considerations"). SECURE will designate the entire amount of the deemed dividend arising from its repurchase of Shares under the Offer as an "eligible dividend" for purposes of the Tax Act and any corresponding provincial and territorial tax legislation.

The "specified amount" for purposes of subsection 191(4) of the Tax Act in respect of each Share is $13.47. Shareholders should consult with their own tax advisors with respect to the income tax consequences of the disposition of their Shares under the Offer.

The full details of the Offer are described in the offer to purchase and Circular, as well as the related letter of transmittal and notice of guaranteed delivery (the "Offer Documents"), copies of which were filed and are available under SECURE's profile on SEDAR+ at www.sedarplus.ca.
