Sherritt Receives Final 2023 Cobalt Dividend and $64 Million Cash Top-up Dividend Under its Cobalt Swap Agreement

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

Sherritt International Corporation ("Sherritt" or the "Corporation") (TSX:S) today confirmed that it has received the 2023 annual maximum volume of cobalt dividends and a $64 million cash top-up dividend, fully satisfying its Cuban partner's current year obligation owed to Sherritt under the Cobalt Swap agreement. In addition, Sherritt intends to pay cash interest on its 10.75% unsecured PIK option notes due 2029 (Junior PIK Notes) in settlement of its July 2023 interest payment. All amounts are in Canadian currency unless otherwise noted.

"We are pleased with the success of the Cobalt Swap agreement, and as a testament to the strong working relationship we have with our Cuban partners, the first year's obligations under the agreement have been met before mid-year," said Leon Binedell, President and CEO of Sherritt International. "The cash received from the ongoing sales of cobalt and the top-up dividend provides significant liquidity to assist in advancing our strategic priorities and supports our intention to pay cash interest on our Junior PIK Notes commencing with our July 2023 payment."

Mr. Binedell continued, "Additionally, this achievement re-enforces our confidence that we will receive the full benefit of the Cobalt Swap over the next four years, providing significant liquidity in excess of our second lien notes maturing in November 2026."

In June 2023, the Moa Joint Venture (Moa JV) approved the final cobalt dividend required to fulfill the 2,082 tonne annual maximum volume of cobalt receivable under the Cobalt Swap agreement. As the total in-kind value of cobalt received under the agreement did not meet the annual dollar minimum of US$114 million (US$57 million per partner), the Moa JV also distributed a cash dividend of US$48.5 million ($64 million). Sherritt continues to sell the cobalt received under the Cobalt Swap to third parties and expects to sell the remaining cobalt and realize all cash receipts on the sales before the end of the year.

General Nickel Company (GNC) has fulfilled its first year's obligation under the five-year Cobalt Swap agreement with the redirection of its 50% share of the cobalt and cash dividends collectively amounting to US$57 million ($76 million) to Sherritt as payment against the GNC receivable.

With receipt of the cash top-up dividend, and cash receipts expected from continuing sales of cobalt, Sherritt intends to make a cash payment of its semi-annual interest on its Junior PIK Notes at the end of July 2023. Satisfying the Junior PIK Notes interest in cash, rather than payment-in-kind, is a key step in providing Sherritt with the ability to provide returns to equity holders.

Sherritt is confident that it will receive its maximum cobalt volume of 2,082 tonnes and any cash top-up dividends required to ensure a total minimum of US$114 million (100% basis) in each of the next four years. The receipt of the remaining dividends will provide significant cash flow to deliver on strategic priorities, including reducing debt and facilitating returns to equity holders. Sherritt expects to receive three of the four remaining annual total Cobalt Swap dividends (US$342 million, approximately $450 million) ahead of the maturity of its second lien notes in November 2026 ($221.3 million as at March 31, 2023).

With the completion of the current year obligations under the Cobalt Swap, any further dividends from the Moa JV in 2023 will be distributed in cash to each partner equally.
