Advanced Innergy Holdings (ASX:AIH) said that its fiscal 2026 revenue is forecast to come in around 162 million pounds sterling, down 14% from its earlier guidance of 188 million pounds sterling, as risks to the guidance it earlier identified materialized with "the extended duration and recent escalation of the Middle East conflict," according to a Friday Australian bourse filing.

Meanwhile, its underlying earnings before interest, taxes, depreciation, and amortization (EBITDA) for the fiscal year ending Sept. 30 is now forecast to be around 20 million pounds sterling for the period, 34% down from 30.2 million pounds sterling guided earlier.

Customers are delaying the progress of new and existing projects while the uncertainty persists. Additional supply-chain pressures, including reduced availability and elevated costs for certain key manufacturing inputs, further constrained gross margins achievable on fixed-price contracts, the filing said.

Its shares plunged 36% in recent trading on Friday, reaching an all-time low.
