Maarten Barmentlo (board member) discloses dealings in Dynavox Group AB to Finansinspektionen. Between 5 December 2023 and 22 October 2026, the trades on record add up to 5 filings.

Purchases make up the whole of the open-market record (5 purchases, €324k). Unlike grants, an open-market purchase is paid for by the insider, at the market price. So far in 2026, the count stands at 2 purchases and no sales.

A typical purchase (the median) is worth €49k. No cluster: in 4 purchases, no other insider of the company bought within 30 days. Looking at 4 purchases old enough to measure, the stock rose over the following 90 days in 50% of cases; the median change was +7.6%. Past outcomes like these are no guarantee of what comes next.

Most recently, on 22 October 2026, the filings show an open-market purchase worth €123k in Dynavox Group AB. Typically, a trade is published a median of 1 day after it takes place. The regulation allows three business days to notify a trade (MAR article 19). These figures are compiled from regulatory filings published by Finansinspektionen. They describe what insiders did and are not a recommendation.
