Q1 2025 ORDERS BY GEO

BACKLOG Good Start to the Year with order and revenue growth

Order Intake grew by 7.6% YoY, driven by a slight recovery in the Electronics segment and positive performance in Electrowinning.
The backlog for the Electrode Tech Business does not reflect the true revenue growth potential due to the rapid in-out dynamics of certain contracts, particularly aftermarket projects

Positive Momentum Continues…

Backlog growth is mainly driven by WTS
WTS: order driven by aftermarket services, which grew by 70%. Key growth geo: Americas and the Middle East
Pools: Strong orders support revenue in Q1 2025 which grew +32%, the best quarter in last 2Ys
