WOODSIDE ASSUMES CONTROL OF BEAUMONT NEW AMMONIA OPERATIONS

Woodside Energy has assumed operational control of the Beaumont New Ammonia (BNA) facility in southeast Texas, following successful completion of performance testing and handover from OCI Global.

BNA has the capacity to produce and export up to 1.1 million tonnes per annum of ammonia and adds diversity to Woodside’s portfolio. BNA has the potential to approximately double US ammonia exports, contributing to regional economic growth.^1^

Woodside CEO Liz Westcott said: “Successful completion of performance testing and assumption of operational control of the Beaumont New Ammonia facility is an important milestone in Woodside’s strategy to invest in new energy products and lower-carbon services.

“In the facility’s operational phase and in the face of current market disruptions, we remain focused on safely delivering ammonia supply to our customers. In the longer term, we retain our goal of supporting the development of a competitive lower-carbon ammonia sector.”

In September 2024, Woodside acquired 100% of OCI Clean Ammonia Holding B.V. The agreed all-cash consideration was approximately $2,350 million, inclusive of capital expenditure through completion, with 80% paid by Woodside at the time of acquisition and a 20% residual now paid on assumption of operational control by Woodside, less adjustments for closing and other items.^2^

Ammonia production at BNA commenced in December 2025. Production of lower-carbon ammonia is now likely to occur after 2026 due to construction issues at the third-party feedstock supply facility.

Woodside continues to advance its position in the ammonia market by progressing offtake agreements from BNA. Woodside has secured offtake agreements at prevailing market prices from the conventional ammonia market, and further sale agreements are being advanced in line with anticipated BNA production output.

This announcement was approved and authorised for release by Woodside’s Disclosure Committee.
