2026 Half Year Results

First half in line; on track to deliver full year guidance

Six months ended 30 June

Nimesh Patel, Group Chief Executive Officer, commenting on the results said:

"We have again delivered resilient mid-single-digit organic growth in revenue and profit, well ahead of IP.  Driving growth ahead of our markets, in spite of external conditions, is now becoming embedded in how we operate and demonstrates the strengths of our business model and strategic positioning in diversified and attractive end markets.  

"Continuing momentum in end markets such as Semicon and Biopharm as well as strong orderbooks, underpin our expectations for second half revenue and profit growth and we are reiterating our full year guidance. 

"Our Together for Growth Strategy is strengthening the Group's differentiated business model, competitive leadership and resilience to drive sustained compounding organic growth at high margins and improving returns on capital.  We remain on track to deliver the medium-term targets we set out for the Group in October 2024; and above these targets in the longer term."

GROUP CHIEF EXECUTIVE OFFICER'S REVIEW

Summary of first half performance

In line with our expectations, Group organic sales growth of 5% was well ahead of global IP of 1.8% or 1.5% excluding China, with strong demand growth across all Businesses and regions.  Organic growth in adjusted operating profit was 6% with the adjusted operating profit margin progressing to 19.8% (H1 2025: 19.3%) and adjusted EPS growing by 9%.  After the impact of currency movements, sales and adjusted operating profit were 5% and 8% higher respectively than in the first half of 2025.

We continue to generate demand in diverse and attractive end markets, against a challenging macroeconomic backdrop, by successfully executing against our operational priorities.  We also invested in future growth through adding sales headcount, customer digital connectivity, digital tools for sales effectiveness, new product development and decarbonisation solutions, with 2026 expenditure weighted to the first half.  I am grateful to my colleagues around the world for their commitment in executing our priorities and delivering for all our stakeholders.

STS organic sales growth was 1%, driven by demand growth of more than double IP, with some shipments specified by customers for delivery in the second half.  As expected, the decline in large project sales in China continued to moderate, while MRO and solution sales again grew strongly.  China sales were down 1% organically compared to the 6% decline in the first half of 2025. 

STS margin of 22.0% was 170bps down organically, reflecting the phasing of shipments and first half weighting of investment in sales and technical capability.  We anticipate second half margin to be higher than the first half, consistent with our typical 45%:55% weighting of adjusted operating profit. This reflects operating leverage from higher second half shipments driving a full year margin broadly in line with that of 2025. 

ETS organic sales growth of 11% was supported by strong demand growth in all three Divisions.  In Process Heating, sales growth was delivered through continued operational progress in driving higher shipments from an expanding order book.  Equipment Heating sales benefited from double-digit Semicon demand (13% of ETS sales in 2025).  In Heat Trace (17% of ETS sales in 2025), we saw the ongoing benefits of having a dedicated team of sales engineers focused on key sectors and geographies.  Operating leverage from sales growth, the absence of lower margin legacy orders and the higher proportion of Semicon and Heat Trace sales, partially offset by ramp up costs for the new Medium Voltage (MV) facility in Ogden, delivered a 220bps organic improvement in ETS margin to 17.2%.

WMFTS organic sales growth was 7%.  In Biopharm, new order intake remained ahead of sales, with Q2 orders reaching the highest level of any quarter since the COVID-related peak of 2021 and ahead of pre-COVID levels, underpinning continuing sales growth.  In Process Industries, we continued to take share in focus sectors such as Mining and Wastewater by successfully deploying our sectorised direct sales model and process expertise.  Operating leverage helped drive an 80bps organic improvement in the WMFTS margin to 27.5%.

Alongside focusing on the execution of our commercial and operational priorities, we continued to make progress in Health and Safety with our all-workplace incident rate1 reducing by 13% and Lost Time Accident Rate2 reducing by 42%.  

We launched our One Planet sustainability strategy in 2021 and had made significant progress by the end of 2025, exceeding key targets, such as a 62% reduction in our absolute scopes 1 and 2 greenhouses gas emissions compared to our 2019 baseline.  In the first half, we launched our refreshed One Planet Roadmap that sets out how we will continue to embed sustainability in our own operations and support people and our local communities, while advancing our customers' sustainability through our products and solutions.

The Board has declared an interim dividend of 50.4 pence (H1 2025: 48.9 pence) per ordinary share representing 3% growth. The dividend will be paid on 13 November 2026 to shareholders on the register at the close of business on 16 October 2026.

Full year guidance

Market environment

IP is an important driver of demand across our three Businesses.  CHR's forecast for global IP in 2026 is 1.9%, (both including and excluding China), compared to a first half IP of 1.8%, (1.5% excluding China).

Exchange rates

The organic growth guidance below, is based upon 2025 results, restated for the impact of the latest exchange rates in 2026.  If exchange rates at the end of July were to prevail through the remainder of the year, there would be a negligible impact on 2025 sales and adjusted operating profit. 

Full year outlook

We remain on track to deliver our full year guidance of mid-single-digit organic growth in Group revenues, well ahead of IP.  Group adjusted operating profit margin is expected to increase on an organic basis over the 2025 margin of 20.0%, with operating leverage driving growth in adjusted operating profit and EPS ahead of the organic growth in revenues.

In STS, the unwind of the strong orderbook at the end of the first half is driving sales as anticipated and we expect second half sales growth to be ahead of the first half.  We also expect margin to be higher than the first half, consistent with our typical 45%:55% weighting of operating profit. This reflects operating leverage from higher second half shipments driving a full year margin broadly in line with that of 2025. 

In ETS, against a strong comparative (H2 2025: +12%) we anticipate high-single-digit sales growth in the second half, with margin slightly ahead of the first half.

In WMFTS, against a strong comparative (H2 2025: +10%), we expect high-single-digit sales growth in the second half, with margin broadly similar to the first half.

As previously guided, we expect corporate costs to be higher than 2025, reflecting increased investment in future growth, such as Digital and Services.  Excluding such investments, the remaining corporate costs are expected to grow broadly in line with inflation.  We anticipate net financing costs, effective tax rate and cash conversion to be similar to 2025 levels.
