Costain posted lower revenue but higher profits in 2025, boosted cash flow, returned money to shareholders, and secured a record £7 billion in future work.

Costain reported a 16% revenue drop to £1.05 billion for 2025, mainly due to reduced road and rail work, but saw a 32% rise in pre-tax profit to £48.2 million. Despite lower construction income, the company boosted cash flow, increased net cash to £189.3 million, and returned £20 million to shareholders via a buyback and a 75% dividend hike. A record £7 billion forward work pipeline—up 30% from 2024—was driven by growth in energy, nuclear, and defence projects, with £1.1 billion in 2026 revenue already secured. The company also confirmed 90% of its current year’s revenue is locked in, and reaffirmed its dividend coverage target.
