Full Year Trading Update

Alumasc, the sustainable building products, systems and solutions group, provides a trading update for the year ended 30 June 2025 ('FY25'), ahead of publishing its FY25 results on 2 September 2025.

Highlights

• Continued execution of the strategy despite challenging market conditions

o Revenue growth of c.12% to approximately £113m (FY24: £101m), underpinned by organic growth significantly ahead of UK construction markets

o Underlying profit before tax ('UPBT')1 expected to be c.£14.2m, approximately 9% above the prior year, in line with market expectations2

• Revenue and profit ahead of prior year across all three divisions
• Strong platform to deliver further significant shareholder value when market conditions improve

Full year performance in line with market expectations

Despite ongoing macroeconomic uncertainty in the majority of its commercial markets, the Group expects to report c.12% revenue growth to c.£113m (FY24: £101m). Excluding the incremental six months' contribution from ARP, this represents organic growth of c.7%, significantly outperforming the estimated 2% growth in overall UK construction activity3.

All three divisions delivered growth in both revenue and profit. The Building Envelope and Housebuilding Products divisions continued their strong momentum, supported by new product introductions and outstanding customer service. UK revenues within Water Management division were impacted by project delays, however this was offset by export sales growth, including faster-than-expected call-offs from a significant project at Chek Lap Kok airport in Hong Kong.

With continued focus on cost management and efficiency, underlying profit before tax is expected to be approximately £14.2m, c.9% above the prior year and in line with market expectations.

Strong financial position

Year end net bank debt (pre-IFRS 16) is expected to be approximately £6m, representing a leverage ratio of c.0.3x. This includes an increased level of trade receivables at 30 June 2025, due to the timing of shipments into the Chek Lap Kok airport project, which is expected to normalise over the first quarter of FY26.

The Group has continued to invest in its organic growth opportunities, and with its strong operating cash generation, and significant headroom against its committed banking facilities, retains substantial capacity to fund its strategic and operational plans.

Paul Hooper, Chief Executive of Alumasc, commented:

"I am pleased to report another year of revenue and profit growth and a performance in line with market expectations.

This strong performance was achieved against a backdrop of challenging market conditions, with macroeconomic uncertainty affecting business and consumer confidence.

We have established plans to mitigate any continued short term challenges, by continuing to focus on winning market share and entering adjacent markets, and by providing excellent customer service and new products. We will also maintain our disciplined approach to capital allocation and our commitment to efficiency improvements.

As market conditions improve, we remain optimistic that our growth strategy and focus on higher-growth environmentally sustainable solutions will deliver significant shareholder value."
