The Mosaic Company is deeply saddened to report that early this morning on Monday, December 15, 2025, a fall of ground incident occurred at the K3 underground mine in Esterhazy, Saskatchewan, resulting in a fatal injury to one employee. No further injuries have been reported. 

Mosaic's Emergency Response Team was activated following the incident. The site has now been secured and all mining activity has been temporarily halted. A full investigation is underway and Mosaic is working closely with all regulatory authorities. Support services are being provided through the company's Employee and Family Assistance Program. 

The safety and wellbeing of our people remain Mosaic’s highest priority. Our thoughts go out to our colleague’s family and friends, all employees, and the broader community. We ask that the family be given privacy at this difficult time.
