Trading Update

Keller Group plc ("Keller" or "The Group"), the world's largest geotechnical specialist contractor, issues a trading update ahead of its interim results for the six months ended 30 June, scheduled for 4 August 2026.

Since the AGM trading update on 20 May, in which the Group reported a strong start to the year, positive momentum has accelerated. The Group has delivered an excellent performance through the remainder of the second quarter with trading in North America, the Group's largest division, materially outperforming management's expectations. The division has benefited from record volumes and a significant increase in customer demand for infrastructure projects and data centres which has more than offset a softening south Florida residential market. During the period, the division has worked on multiple data centre projects and has won several high value infrastructure contracts where clients are focused on timely and quality delivery across complex and/or large scale projects.

Trading across the Europe and Middle East division has been robust for the year to date, with projects in Scandinavia, central Europe and the Middle East offsetting ongoing subdued market conditions in western Europe. The Asia Pacific division is performing broadly in line with management's expectations, with Austral continuing the momentum delivered in 2025 and largely offsetting pricing pressures in the Australia foundations market where activity levels remain strong.

Tendering activity across the Group remains buoyant and, as previously announced, the Group's order book currently sits at a record level of c£1.9bn, increased by the significant multi-year I-40 highway remediation contract.

Full year 2026 outlook

As a result of the strong trading performance set out above, the Group's continued margin discipline and its strong order book, the Board now anticipates that the Group's revenue and underlying operating profit for the full year 2026 will be materially ahead of current market consensus1.

The Group's balance sheet and cash generation remain strong, and the Board remains confident in the Group's strategy and long-term growth prospects.

James Wroath, Chief Executive Officer at Keller, said:

"Our North American operations, which account for around 60% of the Group's revenue, have delivered an exceptional performance across the US and Canada so far this year, supported by increased activity in infrastructure and data centres. This reflects Keller's ability to identify and respond to structural megatrends and pivot to subsectors with strong customer demand which drive business growth.

Together with the robust results across the wider Group, this demonstrates the strength of the Group's market positioning and portfolio as well as our continued disciplined approach to project execution. We remain well positioned to continue delivering value for our customers and returns for shareholders in 2026 and beyond."

As previously announced, the Group will be holding a Capital Markets Day on 14 October 2026.
