Shares in Alumasc dropped by over 13% earlier today after the sustainable building products firm suspended its CEO, Pamela Bingham, pending an investigation into matters relating to her professional conduct.

The announcement comes as the firm published its full-year trading update, in which it recorded a “resilient overall performance in the face of strengthening demand headwinds” in its end markets in the final quarter of the year.

In the year to 30 June, Alumasc expects its revenue to drop by 5% to £107m, while its profit before tax is set to drop by 28% to £10m.

The firm has said that demand in its key commercial markets have been “subdued” by affordability concerns, a constrained planning environment and fragile confidence level”, which have been exacerbated by global geopolitical and macroeconomic instability following the Middle East conflict.

Alumasc said that commercial and operational initiatives to improve its water management division performance is underway, and are "generating a positive initial impact".

Interim executive chair at Alumasc, Vijay Thakrar, stated: "As previously reported, during the second half of FY26 the Alumasc management team have focused on self-help initiatives around operational efficiencies and stronger service levels, to ensure momentum in order intake, which has resulted in a 49% year-on-year increase in our order book.

"This has meant that, despite the unprecedented macroeconomic and geopolitical uncertainty, the group has delivered a performance broadly in line with the expectations set at the Q3 trading update, with strong performances at housebuilding products and building envelope divisions.

“We continue to progress a number of commercial, operational and strategic initiatives within the water management division, to strengthen performance and support future growth. We are still taking a prudent view of how the macro environment will develop but remain focused on these performance improvement initiatives and will provide further details when we publish our full year results in September 2026."
