Insights

Equity ownership and capital markets analyst

Large holder converts and sells 2.5M LandBridge Class A shares at $70.

The report shows LandBridge Holdings, a director and 10% owner of LandBridge Co LLC (LB), converting 2,500,000 OpCo Units and related Class B shares into 2,500,000 Class A shares, then selling those Class A shares in an underwritten public offering at $70.00 per share on November 18, 2025. This reflects a significant secondary sale by a major holder rather than a direct primary issuance by the company.

The structure involves OpCo Units paired with Class B shares that may be redeemed for Class A shares or cash at the issuer’s election, and the disclosure notes that Class B shares do not represent economic interests. After the reported transactions, the filing shows 48,593,505 securities beneficially owned indirectly, indicating that LandBridge Holdings remains a substantial holder even after selling the 2.5 million Class A shares.

The filing also explains prior cancellations of OpCo Units and Class B shares in lieu of tax distributions, and details the control chain through Five Point Energy funds and general partners, with David N. Capobianco able to exercise voting and dispositive power. Future company disclosures may further clarify how these ownership and governance arrangements evolve over subsequent periods.
