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.

Sherritt intends to finance the Transaction from its available cash. 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, and may use its available cash and/or seek to raise additional funds in order to increase the Maximum Consideration Amount. All amounts are in Canadian currency unless otherwise noted.

"The principal purpose of the Transaction is for Sherritt to reduce its outstanding debt and provide near-term liquidity to our noteholders which may not be available otherwise. Sherritt's performance in 2021 and the first quarter of 2022, coupled with expected cash flows, provides an opportunity for Sherritt to pursue its growth strategy, including the expansion at the Moa Joint Venture, while also continuing its efforts to reduce debt to achieve balance sheet strength," said Leon Binedell, President and CEO of Sherritt. "We remain 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:

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 June 1, 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.
