Smurfit Westrock to buy CMPC's Chilean containerboard business for USD 420m

Smurfit Westrock has agreed to buy CMPC's Chilean containerboard and corrugated business for USD 420m, a post-synergy multiple of less than 6 times adjusted EBITDA. The assets are a recycled containerboard mill in Santiago with a paper machine of about 250,000 tonnes a year, a fibre collection network, three corrugated plants and one moulded tray facility. Completion is expected in the first half of 2027, subject to customary conditions including regulatory approvals, and will be funded from Smurfit Westrock's own liquid resources.

  • 2026-09-28 · Edited before publication: Grounding and figures check out against the Business Wire release. Four topics exceeds the one-to-three limit; regulatory approval is a routine closing condition, not a regulatory story, so Regulatory & Legal is removed. Spelling changed to British English (moulded) and the multiple restated as the source puts it (less than 6x post-synergy adjusted EBITDA).
  • 2026-09-28 · Edited before publication: Four topics against the one-to-three rule; Regulatory & Legal removed as approvals are a routine condition. 'Why this matters' presented the company's own claim to market leadership as established fact and is now attributed. Text and figures otherwise fully grounded in the Business Wire release.
