Keller Group shares hit an all-time high after the company said it expects to beat full-year market consensus, with its North America unit exceeding the board's expectations.

Shares were up 558 pence, or 21%, at 32.40 pounds in mid-morning European trading Tuesday. They are currently up 93% over the year to date.

The FTSE 250-listed geotechnical engineering company provided a revenue consensus for the year ending Dec. 31 of 3.15 billion pounds ($4.22 billion) and underlying operating profit of 223 million pounds.

This compares with revenue of 3.09 billion pounds and underlying operating profit of 218.2 million pounds in 2025.

Keller said its North American unit--which accounts for around 60% of group revenue--benefited from record volumes and higher customer demand for infrastructure projects and data centers.

Elsewhere, the company said business across the Europe and Middle East division has been robust for the year to date, while the Asia-Pacific division performed broadly in line with management's expectations.

It said tendering activity remains buoyant and that the order book stands at a record 1.9 billion pounds.

"We remain well positioned to continue delivering value for our customers and returns for shareholders in 2026 and beyond," Chief Executive James Wroath said.
