SigmaRoc shares rise as revenue and earnings grow in 2025

SigmaRoc PLC on Monday cited ‘strong’ cost discipline and synergy delivery as revenue and adjusted earnings rose in 2025.

In a trading update, the London-based limestone and minerals company said revenue grew 3.8% to £1.04 billion in 2025 from £998 million in 2024.

Underlying earnings before interest, tax, depreciation and amortisation was more than £262 million, up 17% from £224.6 million in 2024.

Underlying earnings per share rose to 10.5 pence, up 26% from 8.35p the year before. The underlying Ebitda margin was around 25.3% in 2025, up from 22.5%. This reflected ‘strong cost discipline and synergy delivery’, SignaRoc said.

Return on invested capital improved to over 12% in 2025 from 11.5% in 2024, SigmaRoc said.

The figures include full year contribution from UK and Poland acquisitions.

‘This 2025 update once again demonstrates the resilience and quality of our business,’ Chief Executive Officer Max Vermorken said.

‘We have taken timely actions to capture synergies and further operational improvements, delivering strong progress in operational metrics in this last year.’

He added: ‘Our business is focused on lime and limestone, and I am confident we are well positioned for future growth. Lime is an essential product, that plays a critical role in several key societal trends, from decarbonisation to sustainable construction, to environmental protection and the electrification of the economy. We expect our final 2025 results to be ahead of expectations, and we are well positioned to continue our growth in 2026. With strong positions in all markets and supportive structural growth drivers, the outlook for SigmaRoc remains very positive.’

The company said it expects to release its 2025 results by the end of March.

SigmaRoc shares were up 3.7% to 133.80 pence each on Monday morning in London.
