Worley (ASX:WOR) said the adverse impact of the Middle East conflict on its fiscal 2026 underlying earnings before interest, tax, and amortization (EBITA) is estimated to range from AU$30 million to AU$40 million, according to a Monday filing with the Australian bourse.

The company said it is now unlikely to achieve growth in underlying EBITA in fiscal 2026, but it continues to expect the underlying EBITA margin excluding procurement to be within a range of 9% to 9.5%, with no project cancellations to date due to the conflict.

Worley said the extended duration of the conflict and continued uncertainty are resulting in further delays to existing Middle East-related projects and the commencement and award of new projects in the region, while it continues to target higher growth in aggregated revenue than fiscal 2025.

The company said it anticipates medium- to longer-term growth opportunities from investment in regional pipeline and export infrastructure, and increased global focus on national security for alternate sources of energy, chemicals, and resources.
