Copec said that it would sell, through its forestry subsidiary Arauco, a series of forestry units which own assets largely in the Brazilian state of Parana, which together Copec referred to as Sociedades Forestales Brasilenas.

In a separate statement, Klabin said the deal includes 150,000 hectares (370,658 acres) in Parana state, around 56% of which it considers productive land, as well as 31.5 million metric tons of standing wood, equipment and machinery.

Klabin said the deal should help it purchase less wood from third parties, cutting costs and helping it reach its self-sufficiency targets.

The deal comes as Copec has struggled with slumping earnings, dipping into the red last quarter, as its forestry business suffered from floods, drought and forest fires as the region faces more extreme weather due to the weather phenomenon known as El Nino, coupled with the effects of climate change.

Copec said the sale does not include industrial assets tied to wood panel plants Arauco holds in Brazil, or other forestry assets across the state of Mato Grasso do Sul.

The closing price is subject to regulatory approvals including authorization from Brazil's antitrust watchdog CADE, Copec said, and could depend on factors such as the quantity of wood present when the deal closes.

If the deal is finalized, it should have a positive impact of some $130 million after taxes on Arauco's 2024 results, according to preliminary estimates cited by Copec.
