Dennis W. Johnson: trading record in brief

Dennis W. Johnson is a declared insider of MDU Resources Group Inc (board member), with filings sourced from SEC (Form 4). We count 12 filings; the first trade dates from 21 November 2016 and the latest from 13 November 2025.

On the market, this insider has only ever bought: 2 purchases, €571k in total. Unlike grants, an open-market purchase is paid for by the insider, at the market price. The rest of the record consists of 10 share grants. In 2025 alone, the filings show 1 purchase and no sales.

The newest entry dates from 14 November 2025: a share grant, in MDU Resources Group Inc. The latest purchase dates back some time: it was published 621 days ago, on 10 February 2025. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 1 day. US insiders must file a Form 4 within two business days of a trade. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
