Tor Olav Troim, a director at Borr Drilling Ltd (BORR), has once again put his own money into the offshore drilling company, purchasing 1,000,000 shares on the open market on September 16, 2026. The transaction, priced at $4.30 per share, totaled $4,299,500.00 according to the Form 4 filing disclosed with the SEC.
Following the purchase, Troim’s stake stands at 30,385,941 shares, held indirectly through an entity or trust structure rather than in his own name. That distinction is common among insiders who route holdings through investment vehicles, but the economic exposure to Borr Drilling’s share price remains his.
A Pattern of Repeated Buying
This is not an isolated purchase. Troim has shown up repeatedly in insider filings for Borr Drilling over the past several weeks. Back in mid-August, he added $6 million worth of shares in a single transaction, and just two days after that he came back for another $2.2 million, pushing a two-day total past $8 million at the time, as detailed in an earlier report on whoisbuyingnow.com. The latest $4.3 million buy extends that streak into September and adds to a growing tally of open-market purchases from the same director.
Open-market buys like this one are generally viewed differently from stock grants or option exercises, since they require the insider to spend personal capital at prevailing market prices rather than receiving shares as part of compensation. Academic research on insider trading patterns has found that clusters of open-market purchases by company insiders, particularly when repeated over short periods, tend to correlate with subsequent stock performance more often than isolated single transactions. That said, this correlation is a statistical observation from historical data sets, not a guarantee tied to this specific filing, and it says nothing about what happens next with Borr Drilling shares.
For a company like Borr Drilling, which operates in the cyclical and capital-intensive offshore rig market, insider buying can reflect a director’s read on day rates, contract backlog, or balance sheet conditions that aren’t always obvious from the outside. Troim’s repeated purchases at prices in a similar range this year suggest a level of conviction, but the filing itself only documents the mechanics of the trade: shares bought, price paid, and resulting ownership position.
The Form 4 disclosure is a matter of public record, filed with the SEC as required for company insiders. No additional commentary from Troim or Borr Drilling accompanied the filing.
