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

Sherritt International Corp. ("Sherritt" or the "Corporation") (TSX:S) reminds holders (the "Noteholders") of the Corporation's outstanding (i) 8.50% senior second lien secured notes due 2026 (the "Secured Notes") and (ii) 10.75% unsecured PIK option notes due 2029 (the "Junior Notes", and collectively with the Secured Notes, the "Notes") of the initial expiration date of June 1, 2022 (the "Initial Expiration Date") for the Corporation's previously announced modified Dutch auction in respect of the Secured Notes (the "Secured Notes Dutch Auction") and fixed price tender offer in respect of the Junior Notes (the "Junior Notes Fixed Price Tender Offer" and, together with the Secured Notes Dutch Auction, the "Offers" or the "Transaction") for aggregate cash consideration of up to $50 million (the "Maximum Consideration Amount"), exclusive of accrued and unpaid interest on the purchased Secured Notes. The Initial Expiration Date and additional related information with respect to the Offers was previously announced by the Corporation in its news release issued on May 11, 2022 (the "May 11 News Release").

As further described in Sherritt's Offer to Purchase dated May 11, 2022 (the "Purchase Offer") and the May 11 News Release, the Offers expire at 5:00 p.m. (Toronto time) on the Initial Expiration Date, unless the Offers are extended by Sherritt to 5:00 p.m. (Toronto time) on June 15, 2022 (the "Extended Expiration Date"), as such date and time may be extended or earlier terminated by Sherritt. Noteholders that validly tender and do not withdraw their Notes prior to 5:00 p.m. (Toronto time) on the Initial Expiration Date, as such date and time may be extended or earlier terminated by Sherritt, and whose Notes are purchased by Sherritt pursuant to the applicable Offer, will be entitled to additional cash consideration of $30 per $1,000 of principal amount of purchased Notes (the "Initial Participation Consideration Amount") for the purchase of such Notes, payable on the applicable settlement date (as described in the Purchase Offer). Noteholders should review the Purchase Offer in detail for additional information.

Pursuant to the Transaction, Sherritt will purchase any Junior Notes validly tendered pursuant to the Junior Notes Fixed Price Tender Offer and not withdrawn prior to 5:00 p.m. (Toronto time) on the Initial Expiration Date (the "Initial Junior Notes Purchase"), subject to the terms and conditions set forth in the Purchase Offer, and then have the option to purchase Secured Notes validly tendered and not withdrawn pursuant to the Secured Notes Dutch Auction prior to 5:00 p.m. (Toronto time) on the Initial Expiration Date (the "Initial Expiration Secured Notes Purchase Option"), subject to (i) Sherritt's satisfaction with the Clearing Price (as defined and discussed in the Purchase Offer) for such Secured Notes, (ii) the Maximum Consideration Amount (taking into account the Initial Junior Notes Purchase) and (iii) the terms and conditions set forth in the Purchase Offer. The settlement date for any Notes purchased by Sherritt pursuant to the Initial Junior Notes Purchase and/or the Initial Expiration Secured Notes Purchase Option will be the date that is three business days after the Initial Expiration Date. Junior Notes validly tendered and not withdrawn prior to 5:00 p.m. (Toronto time) on the Initial Expiration Date will have priority in acceptance over Secured Notes validly tendered and not withdrawn prior to the Initial Expiration Date.

If Sherritt exercises the Initial Expiration Secured Notes Purchase Option, the Transaction shall not be extended past the Initial Expiration Date to the Extended Expiration Date. If Sherritt does not exercise the Initial Expiration Secured Notes Purchase Option, Sherritt can extend the Offers past the Initial Expiration Date to the Extended Expiration Date, as may be further extended or earlier terminated by Sherritt as described in the Purchase Offer.

Noteholders that do not validly tender their Notes prior to the Initial Expiration Date shall not be entitled to receive the Initial Participation Consideration Amount and will not have a further opportunity to tender their Notes if Sherritt exercises the Initial Expiration Secured Notes Purchase Option and does not extend the Offers past the Initial Expiration Date.

The Transaction is subject to the terms and conditions described in the Purchase Offer. The above dates and times are subject, where applicable, to the right of Sherritt to extend, reopen, amend and/or terminate the Offers, subject to applicable laws. Noteholders should be aware that their broker, dealer, commercial bank, trust company or other intermediary (each an "Intermediary") will establish their own earlier deadlines for participation in, or withdrawal from, the Offers. Noteholders are encouraged to contact their Intermediary directly to confirm any such internal deadlines.

Additional information relating to the Initial Expiration Date and the Transaction is set out in detail in the May 11 News Release and the Purchase Offer.
