Keller Upgrades Full-Year 2026 Outlook as North America Outperforms on Infrastructure and Data Centre Boom

That is a pretty powerful combination. Higher volumes are good, but higher volumes with margin discipline are even better, because they suggest Keller is not simply chasing revenue at any price.

The company also points to a strong order book of c£1.9bn, supported by the significant multi-year I-40 highway remediation contract. An order book is essentially future work already won, so it gives investors more visibility over coming revenue than a contractor would usually have.

North America infrastructure and data centre demand is doing the heavy lifting

This is the standout part of the announcement. Keller says demand for infrastructure projects and data centres has more than offset a softening south Florida residential market.

That tells you two useful things. First, Keller has enough exposure to stronger end markets to absorb weakness elsewhere. Second, the business is benefiting from exactly the kind of big-ticket, technically demanding work where specialist contractors can often defend pricing better than in more commoditised areas.

The reference to clients being focused on timely and quality delivery across complex and large-scale projects is also worth noting. That plays directly into Keller’s specialist positioning as a geotechnical contractor, which deals with foundations and ground improvement work that is critical to getting major projects built properly.

Europe, Middle East and Asia Pacific are solid rather than spectacular

Outside North America, the picture is still healthy, even if it is less exciting. Europe and the Middle East have been robust overall, with Scandinavia, central Europe and the Middle East offsetting subdued conditions in western Europe.

That mix matters. It shows this is not a story of every region firing at once, but it does suggest Keller’s geographic spread is helping smooth out local weakness.

In Asia Pacific, management says performance is broadly in line with expectations. Austral is continuing the momentum seen in 2025, while pricing pressure in the Australia foundations market is being largely offset, despite activity levels remaining strong.

That last point is a mild caution flag. Strong activity is good, but pricing pressure means competition may be limiting how much of that demand turns into profit. Still, the fact that management says Austral is largely offsetting it suggests the problem is manageable for now.

What “materially ahead of consensus” could mean for investors

Keller has not given a new profit forecast, so the exact size of the upgrade is not disclosed. What we do know is that the previous company-compiled analyst consensus for 2026 was £3,150m of revenue and £223m of underlying operating profit.

Underlying operating profit is profit from normal trading before certain one-off or non-core items. Investors watch it closely because it gives a cleaner view of how the day-to-day business is performing.

When a company says results will be materially ahead of consensus, the market normally starts recalculating earnings expectations quite quickly. In practice, that can be a strong support for the share price, especially when the upgrade is tied to operational performance rather than financial engineering or one-off gains.

Why Keller’s record order book and cash generation matter

There are two extra positives tucked into this update. The first is the record order book of c£1.9bn. The second is management’s statement that the balance sheet and cash generation remain strong.

For a contractor, those are important signals. A large order book without decent cash generation can be risky if projects become working capital hungry or margins slip. Keller is effectively saying it has both demand and financial discipline, which is the combination investors want to see.

The company also highlights continued margin discipline. That is management-speak for being selective about the work it takes on and trying not to let volumes come at the expense of profitability. Given the sector’s history, that is reassuring.

The bullish case for Keller shares after this RNS

• North America is outperforming strongly and is the biggest part of the group.
• Demand from infrastructure and data centres looks structurally supportive, not just a short-lived blip.
• The order book is at a record c£1.9bn, giving better than usual revenue visibility.
• The board says both revenue and underlying operating profit should be materially ahead of consensus.
• Cash generation and the balance sheet are described as strong.

The risks and softer spots investors should not ignore

• South Florida residential is softening, showing not every market is strong.
• Western Europe remains subdued.
• The Australia foundations market is seeing pricing pressure.
• The size of the upgrade is not disclosed, so investors still need hard numbers on 4 August 2026.

My take on Keller’s 2026 outlook upgrade

This looks like a genuinely strong update. The most encouraging part is that the upgrade appears to be driven by real demand, strong execution and a healthy order book, rather than a vague change in tone.

I also like the quality of the markets driving growth. Infrastructure and data centres are both areas where specialist ground engineering matters, and that should play to Keller’s strengths.

The negatives are there, but they do not dominate the story. Soft residential demand in south Florida, subdued western Europe and pricing pressure in Australia are all worth watching, yet right now they look more like local headwinds than group-level threats.

Overall, this RNS reads as a clear positive. Keller is telling the market that trading momentum has accelerated since May, North America is doing better than expected, and 2026 should beat existing forecasts. For retail investors, that is usually the sort of update you would rather own than explain away.

What to watch next from Keller

The next key date is 4 August 2026, when Keller reports interim results for the six months ended 30 June. That should give investors proper numbers on revenue, profit and cash, plus hopefully more detail on how far ahead of consensus management now believes the group can land.

After that, the Capital Markets Day on 14 October 2026 could matter too. If Keller can back this momentum up with a convincing long-term strategy update, the market may start giving more credit to the durability of the growth story rather than treating this as just a strong patch.
