Sherritt Provides an Update on its Operations

TORONTO, February 17, 2026 – Sherritt International Corporation (“Sherritt” or the “Corporation”) (TSX:S)

announced it has reduced operations at its joint venture in Moa , Cuba due to fuel supply constraints

affecting the country. The Corporation expects to pause mining operations and place the processing plant

on standby within the next week during which time, planned maintenance activities will be performed. The

Corporation has received notification that planned fuel deliveries for Moa will not be fulfilled and the timeline

for resumption of deliveries is unknown at this time . The Corporation is actively engaging with relevant

counterparts and evaluating all options for sourcing input commodities.

Currently, there is no immediate impact on operations in Fort Saskatchewan , Alberta . The refinery is

continuing to produce finished nickel and cobalt for sale. The inventory of feed it has available for such

production is expected to last until approximately mid-April.

Operations at Energas S.A. (“Energas”) are continuing as planned without any impact.

Sherritt is evaluating available options to maintain operations and prolong production at Moa and Fort

Saskatchewan while implementing measures to preserve and maximize liquidity. These efforts include

managing expenditures to maintain financial flexibility and exploring potential sources of temporary funding

support. Sherritt expects to be able to provide updated 2026 guidance once it has greater certainty around

the supply chain and timelines for the resumption of full operations at its mine and processing facility in

Moa.
