Shares in West Australian engineering group Decmil rose more than 25 per cent on Wednesday after the company said it expected annual revenue to jump by nearly a third as it profits from a rise in demand to build infrastructure projects such as wind farms.

Decmil said it took in $129 million in revenue during the three months ended March 31, and it now expected annual income to total between $470 million and $500 million. Such a result would be a jump of 30 per cent from its 2022 financial year, Decmil said.
