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 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.
