Itaconix plc: what insiders have been doing
Itaconix plc is a listed company. Its insiders report their share dealings to RNS (LSE). The last twelve months, up to 18 October 2026, brought 3 filings signed by 2 insiders.
Purchases and sales both appear in the filings: 2 purchases (1 insider, €14k) and 1 sale (1 insider, €11k). Netting one side against the other leaves €3,264 of net buying. Unlike grants, an open-market purchase is paid for by the insider, at the market price. One trade stands out by size: a sale of €11k from John R. Shaw, disclosed on 6 October 2026, or 0.037% of market capitalisation. On the buying side, the filings list 1 board member among the declarants.
The most recent open-market purchase was published on 6 May 2026, 164 days ago. Typically, a trade is published a median of 1 day after it takes place. The regulation allows three business days to notify a trade (UK MAR).
For context, the typical company on the same exchange (median of 834 companies) published 6 filings over the same period, against 3 filings here. Our records for Itaconix plc go back to 2023, with 8 purchases and 1 sale on the open market in total.
This summary is built from RNS (LSE) disclosures alone and does not predict where the share price will go.
