Nabors Industries

Anthony Petrello, Chairman and CEO, has final authority over capital allocation and M&A. The firm operates as a public company (NYSE: NBR) with a traditional board-and-management governance structure, not a family-office investment committee. Major capital decisions — rig fleet expansion, acquisitions like Parker Drilling's rig assets, or geothermal investments — are approved at the board level.

Nabors is a publicly traded corporation listed on the New York Stock Exchange. It is not a family office, though the Petrello family holds a significant equity position. The firm's core business is manufacturing and operating drilling rigs, joining a distinct category of asset-heavy public entities that allocators examine for their own direct commodity and energy-services exposure.

Nabors Energy Transition Solutions — a separate entity formed in 2023 — evaluates geothermal, carbon capture, and emissions-monitoring investments that can leverage the parent company's drilling technology. The firm has indicated it prioritizes projects where its rig automation software and high-temperature drilling components offer a technical cost advantage over conventional geothermal developers (per the firm's official communications).

Nabors does not operate an investment fund and is not an LP in third-party energy funds in any disclosed capacity. Its capital deployment has historically taken the form of direct rig purchases, organic R&D, and bolt-on acquisitions. The energy-transition vehicle may eventually pull in partnership capital, but to date the firm has not disclosed any fund-of-funds activity.

There is no public record of Nabors co-investing alongside private equity GPs. The firm's public-company structure tends to favor wholly owned subsidiaries and organic technology development. External collaboration is more common at the engineering and joint-venture level — for example, rig-sharing arrangements with Saudi Aramco — than at the portfolio-company level.
