Halma plc

Halma reported headline revenue growth of 15% and EBIT growth of 27% for the half year. Excluding a one-off benefit in E&A, revenue grew 14% and EBIT grew 23%; on an organic basis, revenue grew 16.7% and EBIT grew 22.7%. First-half adjusted EBIT margin was 22.3%, up 160 basis points, and returns on capital rose 190 basis points to 16.2%. Cash conversion was 79% versus a 90% KPI, net debt to EBITDA was just over 1x, and the company invested GBP 300 million in the half. For the full year, management now expects mid-teens percentage organic constant-currency revenue growth, including continued Photonics benefit, and an adjusted EBIT margin of around 22%.

Marc Ronchetti framed the quarter as evidence that Halma’s sustainable growth model is working across the portfolio, not just in Photonics. He emphasized record half-year results, broad-based organic growth, strong margins, high returns on capital, and the ability to keep investing for future growth while maintaining confidence in long-term compounding. His tone was upbeat and strategic, with repeated emphasis on the combination of long-term discipline and short-term agility.

Carole Cran focused on the mechanics behind the results: 15% headline revenue growth, 27% EBIT growth, 22.3% margin, and 16.2% returns on capital. She detailed first-half investment of GBP 300 million, including nearly GBP 60 million in R&D, around GBP 130 million in acquisitions, and over GBP 100 million in CapEx and working capital, which pulled cash conversion down to 79% but is expected to normalize toward the 90% KPI by year-end. She also noted net debt to EBITDA at just over 1x, a GBP 53 million dividend return, a GBP 148 million net M&A outlay, and an upgraded full-year margin target of around 22%.

Analysts pressed management on the drivers and durability of Photonics growth, especially whether it is tied to customer CapEx, share gains, or a possible replacement cycle. Management said the relationship is embedded and iterative, visibility is directional but limited, and they currently see the business as a tailwind into FY27, while not ruling out future replacement or wider customer diversification. Questions also focused on Safety and Healthcare margins and growth by geography; management said Safety’s margin strength reflected mix, momentum, and strong execution, but further investment will be needed to sustain growth, while Healthcare margins should recover gradually as markets improve.
