Spirax Group (LSE:SPX) reported organic revenue growth of 5% to £1.70 billion in 2025, outperforming global industrial production levels. All three of the company’s divisions recorded organic sales increases, while improved adjusted margins helped lift the group’s organic adjusted operating margin to 20%. However, statutory profit declined during the period as one-off restructuring costs weighed on reported operating profit and margins. Despite this, Spirax improved cash conversion, reduced leverage to 1.5 times EBITDA, increased returns on capital, and raised its dividend.
Performance across divisions was mixed. Steam Thermal Solutions recorded modest organic growth but experienced pressure on statutory margins. Electric Thermal Solutions achieved double-digit organic revenue growth, supported in part by recovering semiconductor demand, while Watson-Marlow delivered mid-single-digit growth as activity in biopharma markets strengthened. Management said a recently completed efficiency and simplification programme is now generating around £40 million in annualised cost savings, providing additional capacity for reinvestment and supporting expectations of further organic growth and margin expansion in 2026 despite ongoing macroeconomic uncertainty.
The company’s outlook is supported by strong financial performance and positive commentary from its latest earnings call. Technical indicators suggest a largely neutral share price trend, while valuation metrics imply the stock may be trading at elevated levels. Management believes its ongoing strategic initiatives and restructuring programme will support long-term performance, even as certain regional markets remain challenging.
