UPM's shareholders approved the WISA Group separation on 31 August. Aspo votes on 7 December. Valmet has not yet approved a plan.
UPM-Kymmene's extraordinary general meeting approved the demerger of its Plywood business on 31 August 2026, seating the board of the new company at the same meeting. WISA Group Plc is expected to complete on or about 31 October and start trading on Nasdaq Helsinki on 2 November. UPM shareholders receive one WISA share for each UPM share held; the Finnish Tax Administration has ruled the demerger tax-neutral, and the Financial Supervisory Authority approved the listing prospectus in July and a supplement in August.
Aspo's board approved its own demerger plan on 3 August 2026. ESL Shipping moves into ESL Shipping Group Plc and the continuing company was renamed Telko Group Plc, on the same one-for-one basis. The extraordinary general meeting is set for 7 December, completion for 31 December, and trading in ESL Shipping Group shares for on or about 4 January 2027. A separate share exchange folds Lighthouse HoldCo's 21.4% direct stake in ESL Shipping into the new company, after which OP Finland Infrastructure LP (about 14.3%) and Varma Mutual Pension Insurance Company (about 10.7%) are expected to be its two largest shareholders.
Valmet is furthest from a vote. Its board announced on 24 July 2026 that it would review separating Biomaterial Solutions and Services from Process Performance Solutions into two listed companies. No plan has been approved. An update is due no later than the full-year 2026 results.

The numbers behind WISA
WISA will operate seven production units across five locations in Finland and Estonia, with capacity of around 785,000 cubic metres a year. Plywood sales were EUR 409 million in 2025 on EUR 55 million of comparable EBITDA, against a 2030 target of more than EUR 550 million in sales and a 13% comparable EBIT margin, with a dividend policy of roughly half of annual profit.
The 31 August meeting also elected WISA's board — Tapio Korpeinen as chair, Mats Nordlander as deputy chair, and Sakari Ahdekivi, Frank Herrmann, Nina Kiviranta and Emmanuelle Picard, each serving until WISA's first annual general meeting.
Valmet itself demerged from Metso in 2013.
The leadership consequences of these three transactions are covered separately by Listeds in Two new listed CEOs, no search, no external hire: two new listed-CEO seats created without a search, filled from inside the parent, against a Large Cap tier that recorded no CEO change in the first half of 2026.
