Costain results for the year to 31st December 2025 show revenue down 16% at 拢1,045.7m (2024: 拢1,251.1m) and pre-tax profit up 32% to 拢48.2m (2024: 拢36.5m).
Adjusted operating profit 鈥� the board鈥檚 preferred metric 鈥� grew by 9% to 拢47.1m (2024: 拢43.1m).
There was a 50% fall in revenue from road building projects and a 25% fall from railways. But these were at least partially offset by growth in the energy sector and from the nuclear & defence division.

Despite the turnover dip, Costain鈥檚 financial metrics all look to be pointing the right way. The net cash position at the end of the year was 拢189.3m (2024: 拢158.5m) after taking account of the 拢10m share buyback programme and higher dividend payments in 2025. Cash from operations was 拢50.7m (2024: 拢41.7m), with the increase reflecting increased adjusted operating profits and working capital timing. Adjusted free cash flow was up from 拢27.1m in 2024 to 拢63.1m in 2025.
In addition, the forward work position 鈥� combining both the order book and the preferred bidder book 鈥� stood at 拢7.0bn at the end of 2025, compared to 拢5.6bn at the half-year point and 5.4bn at the end of 2024. It includes 拢1.1bn of revenue for 2026, equivalent to 90% of forecast revenue for the year.
Chief executive Alex Vaughan said: 鈥淭he group is strongly positioned in structurally growing markets where significant long-term investment is being made to meet critical national needs, and where we work in long-term collaborative partnerships with an increasing number of customers. Our forward work position has grown by 30% to a record 拢7.0bn, almost seven times 2025 revenue, giving good visibility of future work and, combined with our strong balance sheet, underpins our confidence in delivering revenue and operating profit growth in 2026 and a step change in performance in 2027 and beyond."
