UPM completes plywood demerger; WISA Group admitted to Nasdaq Helsinki

UPM-Kymmene's partial demerger of its plywood business was entered in the Finnish Trade Register on 31 October 2026, moving UPM Plywood's assets and liabilities into the newly formed WISA Group Plc. Nasdaq Helsinki approved WISA Group shares for its regulated market, with trading scheduled to start on 2 November under the ticker WISA; UPM shareholders receive one WISA share for each UPM share held.

Why this mattersPlywood now sits in a separately listed company rather than a UPM business unit, giving customers and suppliers a new counterparty while UPM's own share count stays unchanged.

Updates

  • 2026-11-04 · Edited before publication: The source says only that WISA trading was scheduled to start on 2 November and warns that the notice does not confirm it happened. 'Began trading' replaced with 'admitted' and 'scheduled'.
  • 2026-11-04 · Edited before publication: Two phrases in why-this-matters are not in the source: 'forestry-led portfolio' and 'dedicated listed peer among wood-panel producers'. It is rewritten using the source's own point that plywood now sits in a separate listed company. All other facts are grounded.
