Harrison Fenner Bolling: trading record in brief

This profile gathers the share dealings of Harrison Fenner Bolling across 2 companies, led by LandBridge Co LLC and WaterBridge Infrastructure LLC. In total, 9 filings cover trades dated from 15 July 2024 to 18 September 2026.

The open-market record is one-sided, with 2 purchases worth €68k and not one sale. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Outside the open market, there are 7 share grants. Since January 2026: 2 purchases and no sales on the market.

The latest filing, published on 22 September 2026, reports a share grant of €247k in WaterBridge Infrastructure LLC. The clock since the last published purchase (7 January 2026) now reads 290 days. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. 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.
