Next Costain Group Dividend

Costain Group next goes ex-dividend on 16/04/2026. This will be the Final dividend for 2026.

The dividend per share amount is 3.2000p (GBP) and the payment date is 26/05/2026.

Key Dividend Details

Final dividend (FY25): 3.2p per share (up 60% YoY), subject to AGM approval
Full-year dividend (FY25): 4.2p per share (up 75% YoY)
Ex-dividend date: 16/04/2026
Record date: 17/04/2026
Payment date: 26/05/2026
Scrip dividend: Available; election deadline 11/05/2026; scrip reference price to be announced 23/04/2026
Dividend policy/cover: Target cover of 3x adjusted earnings; FY25 adjusted EPS 14.5p implies current full-year cover of ~3.5x (payout ratio ~29%)
Capital returns: Planned £20m share buyback in FY26 (after £10m buybacks in each of FY24 and FY25)

Concise Take

The proposed final dividend of 3.2p sets the FY25 total at 4.2p, with an ex-div date of 16/04/2026 and payment on 26/05/2026.
Cover is comfortably above the 3x target, leaving room for progressive dividends if earnings grow as guided.
Scrip option moderates cash outflow; buybacks signal confidence and support per-share growth.

Dividend Sustainability and Growth Outlook

Earnings and cash support: FY25 adjusted operating profit up 9% to £47.1m; adjusted margin 4.5%. Net cash of £189.3m and strong adjusted free cash flow (£63.1m) underpin distributions. Management still expects to be “highly cash generative.”
Guidance and visibility: FY26 guidance for revenue and operating profit growth but margin around ~4.0% (vs 4.5% FY25) as FY25 contract completions don’t repeat. Record forward work of £7.0bn (~7x FY25 revenue) and 90% of FY26 revenue in hand provide visibility; ambition to move margins >5% medium term supports dividend growth potential.
Policy and capacity: Targeting 3x cover on adjusted earnings suggests scope to grow the dividend alongside earnings. At FY25 EPS (14.5p), a 3x cover would equate to c.4.8p per share; current 4.2p leaves headroom.
Capital allocation: Alongside the dividend, a £20m FY26 buyback and ~£10m p.a. investment in systems/digitalisation are planned. Despite these, year-end FY26 net cash is guided to remain strong (~£175m), indicating capacity to sustain the dividend.
Pension de-risking: No further cash contributions to the DB scheme under the new schedule to Jan 2031, and removal of the pension “dividend parity” constraint improves dividend flexibility.

Structural/Policy Changes Relevant to Dividends

Removal of the dividend parity arrangement with the defined benefit pension scheme (announced 26 Jan 2026), lifting a key constraint on shareholder returns.
Share buybacks: £10m completed in FY24 and FY25; £20m planned for FY26, supporting per-share metrics and complementing the ordinary dividend.
Scrip dividend alternative reinstated, lowering cash outlay if taken up.

Risks and Flags to Dividend Stability

Margin guidance lower in FY26 (~4.0%) due to non-recurring FY25 completions and investment; could temper near-term dividend acceleration despite cover headroom.
Working capital: Management guides to a partial unwind of historic WC benefits in FY26; may reduce year-end net cash to ~£175m alongside higher distributions and buybacks.
Project/programme timing risk: HS2 schedule changes and general contract accounting estimation uncertainty (potential downside of £13.4m) could create volatility.
Regulatory/customer risk in Water and wider UK infrastructure (funding cycles, customer financial health) though AMP8/RIIO-3 pipelines are supportive.
Execution discipline remains critical; benefits from pivot to target-cost/long-term programmes reduce but don’t eliminate contract risk.
