During the standstill period, Pala may increase its beneficial ownership to, but not above, 9.99% of Sherritt’s issued and outstanding common shares, and will have customary pre-emptive rights to maintain its ownership percentage for so long as it continues to beneficially own at least 5% of the Corporation’s common shares. The standstill does not restrict the exercise of Pala’s rights under the Put/Call Rights Agreement dated April 17, 2025 between Sherritt and Pala. Pala has agreed to vote in favour of the Corporation’s board slate at the 2026 annual meeting and at any other shareholder meetings involving the election of directors prior to January 1, 2027.

Effective immediately, Shelley Brown has stepped down from the Board and Brett Richards has been appointed to fill the resulting vacancy. The Board will reconstitute the CEO Search Committee, with Brian Imrie as Chair and Brett Richards and Richard Moat as members. Brett Richards will serve on at least two standing committees of the Board. In addition to the CEO Search Committee, he will join the Governance Committee. When the CEO Search Committee is disbanded following the appointment of a permanent CEO, Brett Richards will join the Reserves, Operations and Capital and Sustainability Committee, and he will be appointed to any new committee formed by the Board during this period.
