In addition to the initial purchase price, an
additional purchase price of up to EUR 15 million may be
payable, depending on the economic development in
Leden. The additional purchase price was estimated in the
acquisition analysis at SEK 56 million (EUR 5 million), which
is discounted to SEK 53 million. During the third quarter of
2025, the estimated purchase price was revalued. The
reversal, recorded as other operating income, adjusted for
discounting, amounts to SEK 53 million
If I understand that Hanza report correctly, they haven’t yet reversed the provision for the additional purchase price of the Leden acquisition. They have only lowered it from 56 to 53 MSEK after Q3. 
Maybe something could still come from there. Arvo’s share of Leden was around 30%.
