UPM-Kymmene Corporation Completes Partial Demerger with WISA Group Plc on Nasdaq Helsinki

UPM-Kymmene Corporation's Partial Demerger and WISA Group Listing

On October 31, 2026, UPM-Kymmene Corporation (commonly referred to as UPM) registered its partial demerger, a strategic move that is set to transform its operational landscape. This demerger will see the establishment of the WISA Group Plc, which has been approved for listing on Nasdaq Helsinki.

The Details of the Demerger

The demerger process began with UPM announcing its plans on April 29, 2026, receiving green light from shareholders. The plan's crux involves the separation of UPM's Plywood business area and its associated assets and liabilities, effectively transferring them to the new entity, WISA Group Plc. This transfer positions WISA Group to operate independently, focusing on the plywood market and enhancing its business prospects.

Nasdaq Helsinki has approved the application for trading WISA Group’s shares, which is set to begin on November 2, 2026, under the ticker symbol "WISA" with the ISIN code FI4000603345. Meanwhile, UPM continues to trade under its established ticker, "UPM," with its shares maintaining a new ISIN code of FI4000603337.

What This Means for Shareholders

The completion of the demerger offers significant benefits to UPM shareholders. For every share they hold in UPM, they will receive a corresponding share in the newly formed WISA Group. This means that shareholders will not only retain their existing investment value in UPM but will also gain new shares in an entity focused solely on the plywood business.

Importantly, the demerger does not alter the total number of shares owned in UPM itself; rather, it reflects a strategic restructuring aimed at enhancing value for all stakeholders via focused operational strategies.

Anticipated Market Impact

The establishment of WISA Group is expected to create a more streamlined focus on the plywood sector, which might lead to better operational efficiency and financial performance. Analysts will be closely observing how this separation affects market dynamics, competitor positioning, and customer loyalty in both companies going forward.

UPM's Commitment to Sustainability

UPM is a company known for its commitment to sustainability, operating with the mission of powering responsible production through its diverse portfolio of renewable fibers and advanced materials. The most recent changes in organizational structure are intended to further strengthen this ethos by allowing both UPM and WISA Group to pursue specialized growth paths, ultimately benefiting the global push toward sustainable resource management.

As a company employing approximately 15,100 people worldwide and generating annual sales of around €9.7 billion, UPM’s shift aims to renew everyday materials and improve value chains through innovation and environmental responsibility.

Conclusion

The upcoming listing of WISA Group on Nasdaq Helsinki marks a new chapter for UPM-Kymmene Corporation. As both companies embark on their respective journeys post-demerger, market participants and investors will be eager to witness the financial performance and strategic initiatives undertaken by UPM and its newly formed counterpart, WISA Group. This strategic shift not only reflects UPM’s revolutionary business strategy but also underscores its commitment to carving out a more sustainable and profitable future in the global market.
