Sherritt Provides Update on Operations at its Refinery
TORONTO, June 22, 2026 – Sherritt International Corporation (“Sherritt” or the “ Corporation”) (TSX:S)
today announced that operations at its refinery in Fort Saskatchewan, Alberta are transitioning to a
shutdown state . Such transition aligns with the Corporation’s previously disclosed expectations, which
contemplated refinery operations continuing until approximately mid -June based on available feed
inventory.
The shutdown is being carried out in a controlled and orderly manner, with safety and environmental
considerations remaining the Corporation’s primary priorities. Sherritt has implemented shutdown
procedures designed to protect employees, contractors, the surrounding community and the environment,
and will retain the personnel and resources required to maintain the refinery in a safe and secure state
during the shutdown period.
The shutdown will continue until mining and processing activities at Moa, Cuba resume and the refinery
feed pipeline is rebuilt. At this time, the Corporation is unable to provide timing guidance for when that will
occur. Sherritt is maintaining its suspension of direct participation in joint venture activities in Cuba as
announced in its May 7, 2026 press release . Sherritt is also continuing to work on a path to resume
operations at the refinery as soon as practicable and is taking measures to preserve liquidity, manage costs
and maintain operational readiness during the shutdown period. During the downtime, the Corporation will
complete necessary maintenance activities that do not require significant capital investment. The
Corporation continues to produce fertilizers and sulphuric acid for resale.
