Harbour Energy plc has closed its recently announced deal to acquire LLOG Exploration LLC for $3.2 billion, expanding its footprint into the US Gulf of Mexico, and building on its core business in Norway, the UK, Argentina, and Mexico.

The company said it will provide updated 2026 guidance—including the impact of the LLOG acquisition and additional details on capital allocation plans—on Mar. 5, 2026, with its full-year 2025 results.

A January 2026 investor presentation indicated previous 2026 capital guidance of $1.7-1.9 billion, exluding impacts of the LLOG and Waldorf acquisitions and Indonesia divestments. That number is down from 2025's $2.3 billion. Without additional details, the presentation noted the LLOG acquisition is expected to increase total capex.

Production from LLOG averaged 36,000 boe/d during 2025, reflecting strong performance across the Who Dat (45%, operated) and Buckskin (33.8%, operated) hubs and the start-up of Leon-Castille (33-48.2%, operated) in October, Harbour Energy said, noting production is on track to increase to 65,000-70,000 boe/d by 2028.
