An announcement from Costain ( (GB:COST) ) is now available.
Costain Group PLC has continued to execute its previously announced share buyback programme, purchasing 132,123 ordinary shares between 1 and 7 April 2026 on the London Stock Exchange at volume-weighted average prices around 187–188 pence. The company plans to cancel all repurchased shares and currently holds no treasury stock, signalling an active approach to capital management and a commitment to returning value to shareholders.
In total, Costain has now bought back 945,682 shares for cancellation under the programme, reducing its share count to 265,769,213 ordinary shares in issue after settlement. The reduced share base is likely to enhance earnings per share over time and may improve market perception of the company’s financial strength and confidence in its future prospects.
The most recent analyst rating on (GB:COST) stock is a Hold with a £180.00 price target. To see the full list of analyst forecasts on Costain stock, see the GB:COST Stock Forecast page.
Spark’s Take on COST Stock
According to Spark, TipRanks’ AI Analyst, COST is a Outperform.
The score is driven primarily by improved financial stability and earnings quality (higher margins, low leverage, solid cash conversion), supported by strong technical uptrend signals. Valuation is reasonable but not deeply compelling, and the key risk tempering the score is the multi-year revenue contraction, which could limit future growth if it persists.
