Mandatum Oyj, classified in the Banks sector, is a listed company based in Helsinki, Finland, founded in 1998. Its insiders report their share dealings to Nasdaq Helsinki. From 18 October 2025 to 18 October 2026, the disclosure feed for Mandatum Oyj logged 36 filings by 33 insiders.

On the market, 16 insiders bought (16 purchases totalling €223k) while 1 insider sold (2 sales totalling €374.7M). No amount is published for 6 filings, which the totals therefore leave out. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Those buying include 8 board members, 5 senior executives and 1 finance chief. Altor Invest 8 AS filed the largest sale, €238.0M, on 24 February 2026, which represents 8.4% of the company's market value.

For context, the typical company on the same exchange (median of 126 companies) published 15 filings over the same period, against 36 filings here. Since 2023, the database holds 44 purchases and 3 sales by insiders of the company.

In all, 9 purchases were made within 30 days of a purchase by another insider of the company. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time. The clock since the last published purchase (21 August 2026) now reads 57 days. Publication is fast: at least half of the trades appear on Nasdaq Helsinki on the same day. For comparison, MAR article 19 gives managers three business days to notify a trade.
