Keller Group reported record first-half results for 2026, highlighting stronger revenue and higher underlying operating profit in the opening six months of the year. According to the company update, constant-currency revenue rose 11%, underscoring solid momentum across the business.

The first-half performance was supported by strong demand tied to data centers, a market that has been a key driver of construction and engineering activity. That demand appears to have helped offset a mixed backdrop elsewhere and gave Keller a boost in both sales and profitability.

For investors following Keller Group H1 2026 results, the main takeaway is that the company entered the year with strong operating momentum. The combination of rising revenue and improved underlying profit suggests the group is benefiting from active end markets and disciplined execution.

The earnings call highlights point to a business that is seeing favorable conditions in important project segments while converting that demand into record first-half numbers. As a result, Keller Group's latest update is likely to keep attention on how long data center-related demand can continue to support growth.
