Masonite International Corporation Experiences a Fire at a Cut-Stock Facility in Stockton, CA

Masonite International Corporation (“Masonite” or the “Company”) announced that a fire broke out yesterday at a non-Masonite facility adjacent to one of the Company’s plants in Stockton, CA and spread to Masonite’s facility. There were no reported injuries to Masonite employees.

The Masonite Stockton cut-stock facility was severely impacted and, after assessing the damage today and communicating with affected employees, it is not expected to be restarted. For employees at the Stockton cut-stock facility, the Company is providing additional support to ease the disruption occurring from this incident and help find new employment opportunities.

The Company operates two other cut-stock facilities, including a new automated facility in Verdi, NV and intends to increase production at those plants to mitigate the impact from the fire.

Based on the current plans, customer impact, if any, is anticipated to be minimal. The company will continue to evaluate the impact on its operations as additional information becomes available.
