Steam Thermal Solutions Shipments and China Trajectory on Track for Full Year

Spirax Group's Steam Thermal Solutions (STS) division reported four-month organic sales growth higher than the first half, supported by shipments from a larger orderbook carried out of June and continuing order momentum. China, which represented approximately 15% of STS sales in 2025, is on track to be in line with 2025 for the full year, with the announcement citing continuing growth in maintenance, repair and operations sales alongside stabilising large project sales. The company confirmed that the second half STS margin will be ahead of the first half, supporting a full-year margin broadly in line with 2025.

Electric Thermal Solutions Benefits from Semiconductor Demand and Process Heating Momentum

The Electric Thermal Solutions (ETS) division sustained the strong organic sales growth recorded in the first half through the four months to October 2026. The announcement highlights strong order intake in Process Heating and Heat Trace across all sectors, while Equipment Heating is benefitting from higher demand from semiconductor wafer fabrication equipment manufacturers. Excluding sales to semiconductor customers — approximately 13% of ETS sales in 2025 — ETS organic sales growth remains above the group's medium-term mid-single-digit target. Operational gearing and manufacturing efficiency gains are expected to deliver a higher second half margin for ETS compared with the first half.

Watson-Marlow Biopharm and Process Industries Drive WMFTS Second Half Improvement

Watson-Marlow Fluid Technology Solutions (WMFTS) recorded higher organic sales growth in Biopharm during the four months to October compared with the first half, with orders remaining ahead of sales. The company reported strong growth in end-user and consumables sales, with expansion-related sales improving as anticipated. Process Industries also delivered continuing strong organic sales growth, supported by market share gains. WMFTS's higher second half organic sales growth is expected to drive a second half margin slightly ahead of the first half, contributing positively to group-level outcomes.

Spirax Group Reaffirms Full-Year Guidance with Improved Debt Position

The group's financial position strengthened during the period, with net borrowings (excluding leases) falling to £541.6 million at 31 October 2026 from £618.2 million at 30 June 2026, reducing the net debt to EBITDA ratio to 1.3x. The company reaffirmed its full-year outlook, expecting mid-single-digit organic revenue growth, a group adjusted operating profit margin above the 2025 level of 20.0%, and cash conversion of approximately 90%. Investors may be watching whether all three divisions maintain their positive margin trajectories through the year-end close, particularly given China's stabilising project pipeline in STS.
