THE ALUMASC GROUP PLC

("Alumasc" or the 'Group')

AGM Trading Update

Alumasc (ALU.L), the premium sustainable building products, systems and solutions Group, provides the following trading update for the first quarter of its financial year ending 30 June 2026 ('Q1 FY25/26' or 'the period'), ahead of its Annual General Meeting, to be held this morning at 10am.

As announced at the FY24/25 full year results, conditions in the Group's core UK residential and commercial markets have been volatile, with demand in a number of sub-sectors at subdued levels. Conditions in a number of these markets have become more challenging through the period, exacerbated by short-term uncertainty surrounding the UK Government's upcoming Autumn Budget. While the Housebuilding Products division has continued its positive momentum over the period, a number of delays in larger new build and RMI projects have constrained UK revenues in the Building Envelope and Water Management divisions, despite a healthy order book and a growing pipeline of opportunities.

Against this backdrop, the Group has continued to demonstrate market outperformance, retaining or growing share in key UK sub-sectors. Further actions are being taken to improve operational efficiency, including targeted cost initiatives where appropriate to mitigate the short-term impact of project delays.

The Group has continued to see encouraging demand in its export markets, with a number of smaller project orders in the period, further validating the potential of its export business. Although, as expected, overseas sales in FY25/26 are likely to be below the prior year, following shipment of the majority of the very large Hong Kong airport project in FY24/25, several significant early-stage export opportunities are being progressed, which are likely to benefit future financial years.

The Group's structural growth drivers remain robust, and with substantial capacity in place across its businesses and a strong balance sheet, the Group is well positioned to benefit from a sustained recovery in UK construction activity. The timing and pace of this recovery remains difficult to predict, and consequently the Board believes it prudent to adopt a cautious approach for the first half of FY25/26, as conditions remain uncertain. The Board still expects a second-half weighting to FY25/26, as announced at the FY24/25 full year results.

Paul Hooper, Chief Executive, commented:

"While short-term macro-economic, fiscal and political headwinds have intensified during the first quarter of this new financial year, we continue to execute our strategy and grow our market share. As previously announced, we expect an H2-weighted performance for FY25/26, and our order book and pipeline remains healthy.

We have demonstrated resilience throughout this period and continue to take proactive steps to grow our market share, enter adjacent markets, and reduce cost and improve efficiency, which will serve the Group well both now and in the future.

Alumasc's medium-term outlook remains very positive, and we remain well positioned to benefit significantly when the market recovers."
