Every trade that managers of OSB Group PLC disclose to RNS (LSE) is tracked on this page. The company is based in United Kingdom. From 18 October 2025 to 18 October 2026, the disclosure feed for OSB Group PLC logged 16 filings by 8 insiders.
Purchases and sales both appear in the filings: 5 purchases (5 insiders, €521k) and 9 sales (5 insiders, €5.8M). Taken together, the sales exceed the purchases by €5.3M. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. The buyers include 3 finance chiefs, 1 senior executive and 1 chief executive. Biggest ticket of the year: €3.5M, sold by Helen Golding and made public on 13 March 2026.
In the case of 4 purchases, another manager of the company was buying within the same 30 days. Such overlaps are known as a cluster signal: distinct people reaching the same decision at about the same time. The latest purchase dates back some time: it was published 67 days ago, on 11 August 2026. Filings reach the RNS (LSE) feed a median of 1 day after the trade. The legal deadline for notifying a trade is three business days (UK MAR). A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify.
Compared with its exchange (833 companies, median 6 filings), a count of 16 filings is above the norm. Our records for OSB Group PLC go back to 2023, with 75 purchases and 29 sales on the open market in total.
