On December 2, 2025, Domtar Corporation ("Domtar") announced that it will permanently close operations at its Crofton, British Columbia, facility. The decision will reduce Domtar's annual pulp production by approximately 380,000 air-dried metric tons of northern bleached softwood kraft (NBSK) pulp. The announcement will affect approximately 350 employees.

The closure is expected to result in an aggregate pre-tax earnings charge of approximately $60 million, including an estimated $19 million in cash charges related to severance and employee benefits, an estimated $33 million in non-cash charges related to the write-off of the carrying amount of property, plant and inventory, and an estimated $8 million in cash charges related to other closure and clean-up costs. Costs in connection with the closure of the Crofton facility are expected to be incurred largely in December 2025, with the remaining in the first half of 2026.

Costs associated with discontinuing production are based on management's best estimates. Although the Company does not anticipate significant changes, actual costs may differ from these estimates due to subsequent business developments. As such, additional costs may be incurred in future periods.

A copy of the news release is being furnished as Exhibit 99.1 to this form 8-K.

## PRESS RELEASE
**For immediate release** 

**Domtar to permanently close Crofton Mill** 

**CROFTON, BC, December 2, 2025** — Domtar today announced it will permanently close operations at its Crofton, British Columbia, facility.

The decision will reduce Domtar's annual pulp production by approximately 380,000 air-dried metric tons of northern bleached softwood kraft (NBSK) pulp. The announcement will affect approximately 350 employees.

"The Crofton mill has been challenged for some time now," said Steve Henry, Domtar paper and packaging president. "Over the last 18 months, Crofton employees worked hard to reduce operational costs and they made some extraordinary gains. Unfortunately, continued poor pricing for pulp and lack of access to affordable fiber in BC necessitates the closure."

"These decisions are made with careful consideration and we recognize the hardship this decision will have on both our employees and the Cowichan Valley community as well as our business partners and the coastal forest sector," said Henry. "Our primary focus is on the safety and well-being of our employees as we navigate the coming weeks."

The site will continue to be managed in compliance with all applicable environmental (and other) laws, including under Domtar's existing *Environmental Management Act* permits.

Domtar is exploring a variety of possibilities for the future of the site.

Domtar is committed to its remaining mills in BC and to working with the government and industry partners to improve access to affordable fiber.
