SigmaRoc (LSE: SRC) – margin expansion and deleveraging underpin unchanged FY26 outlook
Published by Harry Kilby

SigmaRoc (LSE: SRC) reported H126 like-for-like underlying revenue growth of 2.5% y-o-y to £523.1m and an 11.3% increase in EBITDA to £131.2m, with the EBITDA margin improving by 200bp to 25.1%. EBIT increased 3.9% to £89.5m, EPS rose 12.2% to 5.23p, reflecting operational improvements and the refinancing impact, and free cash flow increased 8.2% to £67.0m. Core volumes increased 1%, the first increase in three years, as Q2 improved from a weather-affected Q1 and pricing remained strong. Overall volumes declined 3%, reflecting lower-margin contracts exited in 2025 that remained in the comparative period. Profitability benefited from commercial and operational improvements, cost control and continued CRH Lime and Limestone integration synergies, while covenant leverage declined to 1.66x from 2.04x and last 12 months return on invested capital increased by 50bp to 11.8%.

Industry increased to 36% of revenue from 32% in H125, supported by steel, pulp and paper and chemicals, while Environment represented 22% versus 23%, with improved flue gas treatment and water activity. Construction declined to 42% from 45%, although infrastructure recovered from Q1, including strong German aggregates demand from rail, road and energy projects; soil stabilisation and UK residential activity remained weak, while UK infrastructure was robust. SigmaRoc secured permitting for an additional 64mt of high-grade limestone at Klinthagen, subject to preservation controls and any appeal, and expects its Belgian aggregates plant to be commissioned on schedule and on budget in H226. The €825m investment-grade facility and €300m accordion increase acquisition capacity, while the group received an AAA MSCI ESG rating. The board maintained FY26 expectations in line with consensus of £1,066m revenue, £276m underlying EBITDA, 11.5p underlying EPS and 1.4x leverage, supported by energy transition, re-industrialisation, defence, AI investment and a potential construction recovery, while recognising continuing Middle East, energy-cost and end-demand risks. Interim results are scheduled for 7 September 2026.
