Interroyal Engineering Public Company Limited: what insiders have been doing
Every trade that managers of Interroyal Engineering Public Company Limited disclose to Thai SEC (Form 59) is tracked on this page. The company sits in the Industrials sector and is based in Thailand. It was founded in 1992. In the past year (23 October 2025 to 23 October 2026), 13 filings came from 2 insiders.
Purchases and sales both appear in the filings: 9 purchases (1 insider, €123k) and 4 sales (2 insiders, €843k). Sales outweigh purchases by €720k. Unlike grants, an open-market purchase is paid for by the insider, at the market price. The largest single trade was a sale of €717k by Natnapa Prapatpotipong, published on 31 August 2026.
For context, the typical company on the same exchange (median of 351 companies) published 3 filings over the same period, against 13 filings here. Our records for Interroyal Engineering Public Company Limited go back to 2026, with 9 purchases and 4 sales on the open market in total.
The latest purchase dates back some time: it was published 72 days ago, on 28 August 2026. Most trades are made public on the day they happen. Until a filing is published, the market cannot know about the trade.
Elsewhere in the same sector, our signals recently picked up insider purchases at Bolloré SE and Auroora Yhtiöt Oyj. This summary is built from Thai SEC (Form 59) disclosures alone and does not predict where the share price will go.
