Cardinal Infrastructure Group Inc. Stock: price and insider trades · United States

Cardinal Infrastructure Group Inc. is a listed company. Its insiders report their share dealings to SEC (Form 4). In the past year (18 October 2025 to 18 October 2026), 30 filings came from 10 insiders.

Only purchases show up on the open market, 23 purchases in all worth €9.2M, filed by 8 insiders. Unlike grants, an open-market purchase is paid for by the insider, at the market price. One trade stands out by size: a purchase of €1.5M from Spivey Jeremy Simmons, disclosed on 17 August 2026, or 0.12% of market capitalisation. Among those who bought: 6 senior executives, 1 finance chief and 1 chief executive.

With 30 filings in twelve months, the company is more active than the median of 19 filings across the 5,808 companies we follow on the same exchange. Over the whole record (from 2025), the tally stands at 23 purchases and no sales.

Within a 30-day window, 17 purchases overlapped with buying by a second insider. A cluster is several different insiders buying the same stock within a short window, a pattern studied more closely than a single purchase. The latest purchase dates back some time: it was published 60 days ago, on 18 August 2026. The median gap between a trade and its publication by SEC (Form 4) is 3 days. US insiders must file a Form 4 within two business days of a trade.
