Delayed recognition of revenue of previously communicated Saudi order

The previously communicated order from Serstech’s Saudi partner, Anfas, will be recognized as revenue in 2026, instead of in Q4 2025 as previously stated. The delay is due to the customer not adhering to the approved prepayment plan.

The order value remains unchanged at 2.3 MSEK.
