Costain Group – almost at a Five-Year High and just 9p short of the SQC Target Price of 199.50p – still very undervalued – Finals due soon

Mark Watson-Mitchell – 19.02.2026 

Yesterday almost 1.3m shares in the Costain Group (LON:COST) changed hands in the market, closing 3p higher at 190.60p.

Those trades were far busier than the recent average daily volumes.

The infrastructure group’s shares are just 9p lower than my late January set Target Price of 199.50p, they are just 2.40p lower than their recent High.

At the current price they are trading over 73% higher over the last year, and over 225% higher over the last five years.

Yes – at last – investors, both private and professional, are realising that the £508m-capitalised group’s shares are undervalued.

And I believe that the Final results due to be announced on Tuesday 10^th March will show just how strong the group is currently, boasting loads of cash on hand (£190m) and with a record Order Book (£1.4bn).

Please review my recent comments on the group on Monday,

Powering away - loads of cash and a record Order Book
