Halma plc

Halma reported headline revenue growth of 15% and EBIT growth of 27% in the first half; excluding a one-off benefit in Environmental & Analysis, revenue grew 14% and EBIT 23%. First-half margin was 22.3%, up 160 basis points, and organic revenue growth was 16.7% with price increases averaging between 1% and 2%. Net debt to EBITDA was just over 1x, returns on capital rose 190 basis points to 16.2%, and cash conversion was 79% versus a 90% KPI, with management expecting it to be more in line with the KPI at the full year. For the year as a whole, management now expects mid-teens percentage organic constant-currency revenue growth, including continued premium growth in Photonics, and an adjusted EBIT margin of around 22%.

Marc Ronchetti framed the quarter as another record half year that showed the strength of Halma’s sustainable growth model. He emphasized broad-based momentum across all three sectors, premium growth in Photonics, and the ability to use current performance to reinvest for future growth. His tone was confident and strategic, repeatedly stressing that Halma is built to think long term while staying agile enough to capture emerging opportunities.

Carole Cran focused on the mechanics of the numbers and capital allocation. She highlighted 15% headline revenue growth, 27% EBIT growth, a 22.3% margin, and 16.7% organic growth, while noting that the period included GBP 300 million of investment: nearly GBP 60 million in R&D, around GBP 130 million in acquisitions, and over GBP 100 million in CapEx and working capital. She said cash conversion was 79% in the half but should move closer to the 90% KPI by year-end, net debt to EBITDA stayed just over 1x, and dividends continued to rise, with the group on track for its 47th year of dividend increases of 5% or more.

Analysts pressed management on the drivers and durability of Photonics growth, including whether demand was tied mainly to customer CapEx, whether Halma could broaden the customer base, and whether there could be replacement or aftermarket demand later on. Management said the relationship remains embedded and long term, current demand is mainly tied to build-out and CapEx, visibility is strongest over the next 6 to 12 months, and they see FY27 as a tailwind, but they would not give long-term definitive guidance given the dynamic market. Questions also focused on Safety and Healthcare margins; management said Safety’s strong margin reflected continued top-line momentum, mix, and execution, while Healthcare margins should keep recovering gradually as markets normalize, but they are not being pushed aggressively higher.
