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

Sherritt International Corporation (" Sherritt " or the " Corporation ") (TSX:S), a world leader in the mining and hydrometallurgical refining of nickel and cobalt from lateritic ores, announced today the commencement of 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 ") 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 Transaction is on the same terms and conditions as the Notes purchase transaction completed by Sherritt in June 2022.

Sherritt intends to finance the Transaction from its available cash and from its availability under its syndicated revolving-term credit facility. Sherritt may increase or decrease the Maximum Consideration Amount at any time prior to the Extended Expiration Payment Date (as defined below) in its sole discretion. All amounts are in Canadian currency unless otherwise noted.

"Sherritt is very pleased to offer our noteholders a second opportunity this year for near term liquidity which may not be available otherwise," said Leon Binedell, President and CEO of Sherritt. "We completed our successful Notes purchase transaction in June 2022, which resulted in the reduction of the aggregate principal amount of our outstanding Notes by almost $60 million, and a reduction in our annual interest expense by approximately $5.5 million. With our strong results in 2022 to date, alongside expected cash flows, we have a further opportunity to reduce our debt while also remaining committed to advancing our growth strategy, including our announced expansion plans at the Moa Joint Venture. The June transaction together with today's announced transaction provide our noteholders with liquidity options to receive cash sooner for their Sherritt Notes. Sherritt remains committed to generating value for and acting in the best interests of our stakeholders."

Consideration under the Offers

The following table sets out the Notes and certain payment terms under the Offers, which are discussed further below:

^{(1) Based on the Maximum Secured Notes Bid Price (as defined below), and subject to determining the Clearing Price (as defined below) pursuant to the Secured Notes Dutch Auction process.}

Secured Notes

The Secured Notes will be priced per $1,000 of principal amount of Secured Notes as determined by a modified Dutch Auction process whereby holders may specify either the minimum purchase price they are willing to receive for each $1,000 of principal amount of their Secured Notes (a " Bid Price ") or accept the purchase price for the Secured Notes determined by Sherritt pursuant to the terms of the Secured Notes Dutch Auction (the " Clearing Price "), as described in the Purchase Offer (as defined below), plus, where applicable, the Initial Participation Consideration Amount (as defined below) of $30 per $1,000 of principal amount of Secured Notes. Bid Prices specified for the Secured Notes must be less than or equal to $820 per $1,000 of principal amount of Secured Notes (the " Maximum Secured Notes Bid Price "). Bid Prices in excess of the Maximum Secured Notes Bid Price will not be accepted or used for the purposes of determining the Clearing Price. If none of the holders that tender Secured Notes pursuant to the Secured Notes Dutch Auction specify a Bid Price, the Clearing Price will be the Maximum Secured Notes Bid Price. Holders whose Secured Notes are purchased by Sherritt pursuant to the Secured Notes Dutch Auction will also be entitled to be paid in cash any accrued and unpaid interest from the last interest payment date up to, but not including, the applicable Payment Date (as defined below).

Junior Notes

The purchase price for the Junior Notes pursuant to the Junior Notes Fixed Price Tender Offer is a fixed price of $520 per $1,000 of principal amount of Junior Notes (the " Junior Notes Fixed Price ") plus, where applicable, the Initial Participation Consideration Amount of $30 per $1,000 of principal amount of Junior Notes. The purchase price for the Junior Notes pursuant to the Junior Notes Fixed Price Tender Offer determined by Sherritt takes into account all accrued interest from the last interest payment date as part of the overall purchase price. Accrued interest in respect of the Junior Notes will not be paid in respect of any Junior Notes purchased by Sherritt pursuant to the Junior Notes Fixed Price Tender Offer. Junior Notes that are validly tendered and not withdrawn will have priority in acceptance over Secured Notes validly tendered and not withdrawn as discussed in further detail below.

Additional Initial Participation Consideration

Holders of Notes that validly tender and do not withdraw their Notes prior to 5:00 p.m. (Toronto time) on November 16, 2022 (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 "), payable on the applicable Payment 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.

Pursuant to the Transaction, if the Offers are extended by Sherritt to the Extended Expiration Date, Sherritt will purchase any additional Junior Notes validly tendered and not withdrawn pursuant to the Junior Notes Fixed Price Tender Offer prior to 5:00 p.m. (Toronto time) on the Extended Expiration Date (the " Additional Junior Notes Purchase "), subject to the terms and conditions set forth in the Purchase Offer, and then have the option to acquire Secured Notes validly tendered and not withdrawn pursuant to the Secured Notes Dutch Auction prior to 5:00 p.m. (Toronto time) on the Extended Expiration Date (the " Subsequent Secured Notes Purchase Option "), subject to (i) Sherritt's satisfaction with the Clearing Price for such Secured Notes, (ii) the Maximum Consideration Amount (taking into account the Initial Junior Notes Purchase and Additional 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 Additional Junior Notes Purchase and the Subsequent Secured Notes Purchase Option will be the date that is three business days after the Extended Expiration Date (the " Extended Expiration Payment Date ", and together with the Initial Expiration Payment Date, the " Payment Dates " and each a " Payment Date ").

Junior Notes and, if Sherritt exercises the Initial Expiration Secured Notes Purchase Option, Secured Notes that in each case are tendered prior to 5:00 p.m. (Toronto time) on the Initial Expiration Date may be withdrawn at any time prior to 5:00 p.m. (Toronto time) on the Initial Expiration Date, but not afterwards unless otherwise required by law. If Sherritt does not exercise the Initial Expiration Secured Notes Purchase Option, Junior Notes tendered after 5:00 p.m. (Toronto time) on the Initial Expiration Date and prior to 5:00 p.m. (Toronto time) on the Extended Expiration Date, and Secured Notes tendered at any time prior to 5:00 p.m. (Toronto time) on the Extended Expiration Date, may be withdrawn at any time prior to 5:00 p.m. (Toronto time) on the Extended Expiration Date, but not afterwards unless otherwise required by law.

Sherritt may amend the Maximum Secured Notes Bid Price and/or the Junior Notes Fixed Price in its sole discretion, provided that if at the time of any such amendment there are fewer than three business days until the applicable Expiration Date for the Offers, Sherritt will extend the Offers so that at least three business days remain until the applicable Expiration Date.
