Change in reporting currency - publication of historical comparative reporting data

Hill & Smith PLC ("Hill & Smith" or "the Group"), a leading provider of solutions that enhance the resilience of vital infrastructure and the built environment, provides historic comparative financial data in US dollars ahead of the change in its reporting currency.

As announced on 11 March 2026, the Group will adopt the US dollar for reporting, with effect from the interim results announcement for the six months ending 30 June 2026. This reflects the growth of the Group's US footprint and the increasing proportion of the Group's revenues and operating profits originating in US dollars (63% and 79% respectively in 2025). The Board believes that adopting US dollar reporting will provide investors and other stakeholders with greater transparency of the Group's performance and reduce foreign exchange volatility over time.

Commencing with the interim dividend for the year ending 31 December 2026, due to be paid in January 2027, dividends will be declared in US dollars. Shareholders will continue to receive dividends in sterling unless they elect to receive them in US dollars.

The Group's primary consolidated financial statements, together with selected notes, for the years ended 31 December 2025 and 31 December 2024, and the six months ended 30 June 2025, re-presented in US dollars are set out here for comparative purposes:
