Alumasc Group plc (LSE: ALU) shares surged on 3 February 2026, rising 6.21% to GBX 260.22 during the morning session. The gain followed the release of the company’s interim results for the six months ended 31 December 2025, which reflected lower first-half financial performance compared with the prior year but pointed to improved momentum in the second half.

The update highlighted that H1 FY26 results were impacted by delayed project activity linked to building safety regulations, affordability pressures, and uncertainty around the Autumn Budget. Despite these headwinds, management indicated that performance remains aligned with expectations for the full financial year.

Lower H1 FY26 Earnings with Balance Sheet Movements in Focus

Group revenue for H1 FY26 declined to GBP 50.4 million from GBP 57.4 million in H1 FY25. The prior-year period included GBP 5.5 million from the Chek Lap Kok airport project in Hong Kong, compared with GBP 0.1 million recognised in the current period, with further revenues expected in H2 FY26.

Underlying operating margin reduced to 8.9% in H1 FY26 from 14.1%, reflecting the lower revenue base. Underlying profit for the period fell to GBP 4.0 million in H1 FY26 from GBP 7.5 million a year earlier, while statutory profit before tax decreased to GBP 4.0 million from GBP 6.5 million. The interim dividend was maintained at GBX 3.5 per share.

Net debt increased to GBP 7.7 million in H1 FY26 from GBP 4.6 million at the same point last year, largely due to a temporary working capital build ahead of expected higher H2 activity. The company also recorded a GBP 0.5 million non-underlying cash receipt from the sale of a property during the period.

The defined benefit pension scheme position improved, with an IAS19 surplus of GBP 7.1 million as of December 2025, compared with GBP 3.5 million a year earlier.

Order Book Expansion Improves Second-Half Visibility

Investor attention centred on the outlook commentary, which highlighted a growing order book and increased visibility into the second half. Excluding the Chek Lap Kok project, the order book was 27% higher than December 2024 and 50% higher than December 2023. The pipeline includes UK and overseas infrastructure-linked opportunities, alongside early signs of improving confidence in certain end markets.

Management reiterated that results are weighted toward H2 FY26 and stated confidence in meeting expectations for the year ending June 2026.
