21 October 2026 ( EPIC : SRC / Market : AIM / Sector : Construction Materials ) SIGMAROC PLC ( ' SigmaRoc ' , the ' Group ' or the ' Company ' ) Q3 Trading Update Strong Q3 performance underpins confidence in full year expectations¹ SigmaRoc , the European lime and minerals Group , is pleased to provide an update on trading for the nine months to 30 September 2026 ( the ' Period ' ) . Highlights : • Improvement in revenues , EBITDA and margins across the first nine months of the year ; Revenue increased 2.5 % in the Period to £ 795m ( 2025 : £ 775m ) ; Underlying EBITDA increased 7.5 % to £ 207.3m ( 2025 : £ 192.9m ) ; Underlying EBITDA margin improved to 26.1 % ( 2025 : 24.9 % ) , up 120bps ; Volumes in Q3 evolved broadly in line with the first half ; Acquisition of AB Dolomitas for € 110m ; The Board remains confident in full year expectations¹ . Operational delivery Further to our H1 update , operational discipline has supported growth in EBITDA and EBITDA margins in the Period , both showing improvement against the prior period comparator.² All end market sectors ( industry , environment and construction ) demonstrated revenue growth in Q3 although some geographic markets remain more challenging than others . The industrial and environment sectors showed similar trends to H1 , whilst the construction sector returned to growth in Q3 after a slight decline in the first half . Total volumes demonstrated some improvement in Q3 , evolving in line with the first half of the year . An improved performance from infrastructure , industrial and environmental markets has mostly countered the very subdued conditions that have remained in residential construction markets across Europe . Strategic delivery Acquisition of AB Dolomitas for € 110m , a leading Lithuanian dolomite business with 3.5m tonnes of annual production of high - quality dolomite and ~ 45 years of reserves and resources . The acquisition aligns with SigmaRoc's continued focus on high - quality minerals businesses and serves to develop our presence in the Baltics . Outlook The Group continues to demonstrate resilience against a backdrop of subdued activity in certain end markets , and amidst geopolitical and macroeconomic uncertainty . Whilst there are potential catalysts for improved market conditions , the timing and extent of this remains difficult to predict . However SigmaRoc is well positioned to benefit from improved conditions , as and when they occur . The Board's view on the full year 2026 outlook remains unchanged.¹
