GreenFirst Forest Products Inc. (TSX: GFP) today announced a temporary curtailment of certain operations in order to reassess its options, following Kap Paper's decision to begin an orderly idling of operations at its Kapuskasing paper mill.

In a press release, GreenFirst said, "The announced idling of Kap Paper — GreenFirst's primary customer for wood by-products — significantly worsens the challenge of managing these residual materials in Ontario, Canada. This marks the fourth pulp and paper mill to close in the province over the past two years. The two remaining pulp and paper mills in Western Ontario cannot, on their own, absorb the full volume of chips and biomass generated by sawmill operations across the province.

"These tough times have been exacerbated by tariffs and resulting economic uncertainty, the company added.

Employees of GreenFirst have been informed that, effective October 6, 2025, the company will reduce sawmill operations at its Kapuskasing, Hearst, and Cochrane facilities in Ontario for the equivalent of one week. The curtailment at the Kapuskasing sawmill could extend beyond this period, given the site's location and the additional challenges it may face.

This measure will be reassessed as the situation evolves and in light of broader challenges currently affecting the forestry sector, including:

1. Elevated duties and tariffs on lumber exports to the United States;

2. Ongoing uncertainty in lumber markets; and

3. Currently low lumber prices.

Kiln and planer mill operations will continue as scheduled, without interruption; only sawmill operations will be affected by this temporary curtailment. In total, approximately 140 direct employees will be impacted by this decision.

"We are navigating a period of significant uncertainty, marked by the idling of Kap Paper and challenging market conditions. We are doing everything possible to protect our operations, support our employees, and work with governments to find viable solutions for GreenFirst's future," said Joël Fournier, GreenFirst's CEO.

GreenFirst noted that it remains committed to keeping its employees, shareholders, and other stakeholders informed as the situation develops.
