Spirax-Sarco Engineering, a leading industrial engineering company, reported strong financial results for 2025, with 5% organic sales growth and a 6% increase in adjusted operating profit. The company cited pricing and cost discipline as key factors in maintaining its high 20% operating margin, despite currency and tariff headwinds. Each of Spirax-Sarco's three business divisions - Steam Thermal Solutions, Electric Thermal Solutions, and Watson-Marlow - delivered growth and margin improvements during the year.

Why it matters

Spirax-Sarco's performance in 2025 demonstrates the company's ability to navigate a challenging macroeconomic environment and maintain its position as a leader in the industrial engineering sector. The company's diversified business model and focus on operational efficiency have allowed it to deliver consistent growth and profitability, even in the face of global economic uncertainty.

The details

Spirax-Sarco's Steam Thermal Solutions division saw organic sales rise 1%, with the company emphasizing growth in maintenance, repair, and operations (MRO) and 'solution sales' to offset weaker demand for large projects, particularly in China and Korea. The Electric Thermal Solutions division delivered 11% organic sales growth, driven by strong demand across all three of its sub-divisions and operational improvements. The Watson-Marlow division grew 6%, with the biopharmaceutical recovery supporting accelerating sales growth in the second half of the year.

• Spirax-Sarco completed a significant restructuring program in 2025, delivering £40 million in annualized savings.
• The company expects to spend the remaining £11 million of the restructuring costs in 2026.
