Keller Group stock gains 4.42 percent on I-40 contract

Keller Group stock gained 4.42 percent to GBp 3,452.00 on the London Stock Exchange at 12:10 p.m. London time on September 28, 2026. The move followed a new USD 650.0 million contract variation for the I-40 highway reconstruction in the United States, giving the ground engineering specialist a clear infrastructure-driven catalyst.

USD 650.0 million order expands visibility

According to Investegate on September 28, 2026, Keller secured an additional USD 650.0 million work package for the I-40 reconstruction. The project now represents USD 1.0 billion of secured work, with delivery expected to extend across three to four years.

The announcement puts Keller's order book at GBP 2.4 billion and keeps its 2026 full-year expectations unchanged. That combination matters for investors because the contract adds multi-year revenue visibility rather than a single-period boost.

Stock trades near its yearly high

Keller shares traded between GBp 3,312.00 and GBp 3,488.00 during the September 28, 2026 session, with volume at 63,682 shares when the quote was captured. The stock's 52-week range was GBp 1,404.00 to GBp 3,518.00, leaving the latest price 1.88 percent below the yearly high.

The market value stood at GBP 2.4 billion on September 28, 2026. The sharp daily gain therefore arrived with the stock already close to its annual peak, making execution of the new US work and delivery against the unchanged 2026 expectations central to the next phase of the story.

Capital Markets Day comes next

Keller Group's investor centre lists its interim results for the half year ended June 30, 2026, as published on August 4, 2026, and schedules the next event, a Capital Markets Day, for October 14, 2026, according to Keller Group. That date gives investors the next formal checkpoint for the order book, regional execution and medium-term growth plans.
