Impax Environmental Markets plc: what insiders have been doing
This page follows insider dealings at Impax Environmental Markets plc as filed with RNS (LSE), a company from the Banks sector. Between 18 October 2025 and 18 October 2026, 10 insiders published 10 filings.
Only sales appear on the open market, 10 sales in all totalling €519k, filed by 10 insiders. The totals exclude 5 filings filed without an amount. At €176k, the sale published on 19 May 2026 by Glen Suarez is the largest of the period (0.073% of market cap).
Most trades are made public on the day they happen. For comparison, UK MAR gives managers three business days to notify a trade. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning.
Compared with its exchange (833 companies, median 6 filings), a count of 10 filings is above the norm. Our records for Impax Environmental Markets plc go back to 2023, with 7 purchases and 10 sales on the open market in total.
Elsewhere in the same sector, our signals recently picked up insider purchases at Redwood Trust Inc and First Guaranty Bancshares, Inc. Source: insider filings from RNS (LSE). Past trades are no guide to future returns.
