Woodside (NYSE: WDS) assumes control of Beaumont New Ammonia facility in Texas

Rhea-AI Filing Summary

Woodside Energy Group has taken operational control of the Beaumont New Ammonia (BNA) facility in southeast Texas after completing performance testing and handover from OCI Global. The plant can produce and export up to 1.1 million tonnes of ammonia per year, expanding and diversifying Woodside’s portfolio. In 2024, Woodside agreed all-cash consideration of approximately $2,350 million for OCI Clean Ammonia Holding B.V., with 80% paid at acquisition and the remaining 20% now paid upon assuming operational control, subject to closing adjustments. Ammonia production at BNA began in December 2025, and Woodside has secured conventional ammonia offtake agreements at prevailing market prices, though lower-carbon ammonia output is now expected after 2026 due to construction issues at a third-party feedstock facility.

Insights

Energy infrastructure and strategy analyst

Woodside completes ammonia platform build-out but faces timing risk on lower-carbon phase.

Woodside has assumed control of the Beaumont New Ammonia facility in Texas, following performance testing and handover from OCI Global. The plant’s up to 1.1 million tonnes per annum ammonia capacity materially strengthens Woodside’s position in the global ammonia market and broadens its portfolio beyond traditional hydrocarbons.

The move follows Woodside’s approximately $2,350 million all-cash acquisition of OCI Clean Ammonia Holding B.V., with 80% paid at signing and the 20% balance triggered by this operational handover, subject to adjustments. This shifts the transaction fully into the operating phase, with associated cash outlay now substantially complete.

Ammonia production at BNA started in December 2025, and Woodside has secured offtake at prevailing market prices from the conventional ammonia market, with further agreements advancing. However, production of lower-carbon ammonia is now expected after 2026 due to third-party feedstock construction issues, introducing schedule risk to the lower-carbon strategy even as conventional volumes ramp.

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.

²  The consideration is not capital expenditure and the residual payment will be separately disclosed in the 2026 consolidated statement of cash flows.

This marks the transition from project delivery to full operations within Woodside’s portfolio and completes the acquisition handover milestone.

What is the production capacity of Woodside’s Beaumont New Ammonia (BNA) facility?

The Beaumont New Ammonia facility can produce and export up to 1.1 million tonnes of ammonia per year. This scale significantly expands Woodside’s ammonia footprint and has the potential to approximately double US ammonia exports, supporting regional economic growth and trade flows.

How much did Woodside pay for OCI Clean Ammonia Holding B.V. linked to BNA?

Woodside agreed an all-cash consideration of approximately $2,350 million for OCI Clean Ammonia Holding B.V. Around 80% was paid at acquisition in September 2024, with the remaining 20% paid upon Woodside assuming operational control of Beaumont New Ammonia, subject to closing and other adjustments.

When did ammonia production start at Woodside’s Beaumont New Ammonia facility?

Ammonia production at the Beaumont New Ammonia facility began in December 2025. Since then, Woodside has been progressing offtake agreements, securing contracts at prevailing market prices from the conventional ammonia market as it ramps output from the newly commissioned plant.

Why is lower-carbon ammonia from Beaumont New Ammonia delayed beyond 2026?

Production of lower-carbon ammonia is now likely to occur after 2026 because of construction issues at a third-party feedstock supply facility. This affects timing for the lower-carbon phase, although Woodside continues advancing its broader lower-carbon ammonia ambitions and related offtake strategy.

What offtake strategy has Woodside adopted for Beaumont New Ammonia output?

Woodside has secured offtake agreements from the conventional ammonia market at prevailing prices and is advancing further sale agreements aligned with anticipated Beaumont New Ammonia production. This approach aims to place volumes into existing ammonia demand while longer-term lower-carbon opportunities continue to be developed.
