Sherritt Agrees to Purchase $90 Million of Secured Second Lien and Junior Notes Pursuant to Oversubscribed Offers

NOT FOR DISTRIBUTION TO UNITED STATES NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES

Sherritt International Corp. ("Sherritt" or the "Corporation") (TSX:S) announced today the results of its offers to purchase (i) its outstanding 8.50% senior second lien secured notes due 2026 (the "Secured Notes") pursuant to a modified Dutch auction process (the "Secured Notes Dutch Auction") and (ii) its outstanding 10.75% unsecured PIK option notes due 2029 (the "Junior Notes", and collectively with the Secured Notes, the "Notes") pursuant to a fixed price tender offer process (the "Junior Notes Fixed Price Tender Offer" and, together with the Secured Notes Dutch Auction, the "Offers" or the "Transaction").

Having reviewed the positive results of the Offers, Sherritt determined it would increase the Maximum Consideration Amount (as defined in the Purchase Offer, defined below) from $50 million to $80.4 million and not extend the Offers past the initial expiration date of November 30, 2022. With the increased Maximum Consideration Amount, we have fully satisfied our obligations under the support agreements with the two supporting noteholders as detailed in our press release dated November 14, 2022. As a result, the Transaction is concluded at this time.

"We are delighted by the strong results of our second note purchase transaction in 2022. We have again been able to retire long-term debt at a discount and further reduce our interest expense," said Leon Binedell, President and CEO of Sherritt. "With our initial note purchase transaction completed in June and this subsequent oversubscribed purchase, we will reduce our aggregate principal amount of outstanding notes by approximately $150 million or 35% from the beginning of the year, and our annual interest expense by approximately $13 million. These note purchases reinforce our positive outlook on our operations and together with Sherritt's recent swap agreements, will strengthen our balance sheet and continue to generate value for our stakeholders."

The following table sets out the purchase price per $1,000 of principal amount of Notes, the aggregate purchase price and corresponding principal amount for each series of Notes to be purchased under the Offers.

In addition, Sherritt will pay an aggregate of $720,000 in cash to holders whose Secured Notes are purchased by Sherritt pursuant to the Secured Notes Dutch Auction in respect of accrued and unpaid interest from the last interest payment date up to, but not including, the Payment Date (as defined below) in respect of such purchased Secured Notes.

The detailed terms and conditions of the Offers were set forth in Sherritt's Offer to Purchase dated November 2, 2022, as amended by the notice of variation and extension dated November 14, 2022, (the "Purchase Offer").

All Junior Notes validly tendered and not withdrawn, and all Secured Notes validly tendered at or below the Secured Notes Clearing Price (as defined in the Purchase Offer) and not withdrawn, will be accepted for purchase by Sherritt subject to the terms and conditions set forth in the Purchase Offer. Payment for Notes accepted for purchase pursuant to the Offers will be made by Sherritt on the settlement date of December 5, 2022 (the "Payment Date").

National Bank Financial Markets acted as dealer manager, Kingsdale Advisors acted as depositary and as information agent, and Goodmans LLP acted as Sherritt's legal advisor in connection with the Transaction.
