Trading update

12 March 2026

Halma, the global group of life-saving technology companies focused on growing a safer, cleaner, healthier future for everyone, every day, today releases its scheduled trading update ahead of its financial year end on 31 March 2026.

Further strong progress in the second half, consistent with existing guidance

We have made further strong progress in the second half of this financial year to date, consistent with the upgraded guidance given in our Half Year results published in November 2025. This progress further extends our track record of delivering strong, compounding growth and returns, and puts us on course to deliver our 23rd consecutive year of record Adjusted profit1.

While our companies continue to experience varied conditions in their end markets and operate in an increasingly uncertain economic and geopolitical environment, we have delivered broad-based growth across the Group as we continue to benefit from the strengths inherent in our Sustainable Growth Model. These include our participation in diverse end markets where growth is supported by long-term growth drivers, the autonomy and agility our Model provides our companies to respond rapidly to changing market conditions, and the alignment of our exceptional talent across the Group behind our purpose of growing a safer, cleaner, healthier future for everyone, every day.

Based on our progress in the year to date and our current expectations for the remainder of the year, we continue to expect that we will deliver, in the year as a whole, mid-teens percentage organic constant currency2 revenue growth, including a continued benefit from premium growth in photonics within the Environmental & Analysis Sector, and an Adjusted EBIT margin3 (excluding the one-off profit in the first half) of around 22%4. We also expect our full year cash conversion to be in line with our KPI of 90%, supporting our ongoing strategic investment in future organic growth and in acquisitions, and ensuring that we maintain a strong financial position.

This guidance is supported by order intake which remains ahead of both revenue in the year to date and the comparable period last year.

The appreciation of Sterling is expected to have a negative currency translation effect on the Group's results5.

Record investment in acquisitions; healthy acquisition pipeline

We have completed five acquisitions in the year to date, three since the half year ended 30 September 2025, across the Group's three sectors, with a record £451m invested (on a maximum total consideration basis6). We continue to have a healthy acquisition pipeline across all three sectors.

Full Year Results

The Group's results for the year ending 31 March 2026 will be released on 11 June 2026.

Notes:

1. Adjusted profit is Adjusted profit before tax, amortisation and impairment of acquired intangible assets, acquisition items, and profit or loss on disposal of businesses.

2. Organic constant currency measures exclude the effect of movements in foreign exchange rates on the translation of revenue and profit into Sterling, as well as acquisitions in the year following completion and disposals.

3. Adjusted EBIT is earnings before interest and tax, and before amortisation and impairment of acquired intangible assets, acquisition items, and profit or loss on disposal of businesses. Adjusted EBIT margin is defined as Adjusted EBIT expressed as a percentage of revenue.

4. Our Adjusted1 EBIT margin guidance excludes the one-off profit from the Nuvonic transaction which was completed in the first half of this year (see note 7 below).

5. Sterling has strengthened in the year relative to many currencies, including the US Dollar and Euro and the currency translation impact on the Group's results for the financial year ended 31 March 2026 is expected to be negative. Based on exchange rates of Sterling/US Dollar 1:1.34 and Sterling/Euro 1:1.16, we would expect approximately a £63m negative revenue effect and approximately a £14m negative profit effect in the 2026 financial year, compared to the 2025 financial year.

6. Of the five acquisitions made in the year to date, Nu Perspectives Limited and MC Steering B.V. (Brownline) were reported in the Group's half year results announcement. Since that time, we have made three further acquisitions (considerations given are all on a cash- and debt-free basis):

· E2S Group Ltd, a manufacturer of high-performance safety notification, initiation and detection devices primarily used in highly hazardous environments in heavy industries and complex manufacturing, acquired in December 2025 for £230m;

· Safetec Srl, a provider of customised fire and gas safety solutions for large-scale, complex and high-risk industrial projects, acquired in January 2026 for €72.5m (approximately £63m); and

· Altomed, a UK-based manufacturer and distributor of specialised ophthalmic instruments and consumables, acquired in February 2026 for £29m, as a bolt-on for MST.

Maximum total consideration is on a cash- and debt-free basis.

7. On 15 May 2025, Nuvonic, an Environmental & Analysis Sector company, granted FluidSmile Fluid Tech Ltd (FluidSmile), a longstanding partner of Nuvonic in China, an exclusive trademark licence and related manufacturing and distribution rights to sell certain Nuvonic products in China and other agreed southeastern Asian markets, for RMB95m (£9.3m). Nuvonic also acquired a 35% associate investment in FluidSmile for RMB95m on the same date. As a result of these transactions, one-off revenue of £9.3m and profit of £8.6m were recognised in the current financial year.

8. This Trading update is based upon unaudited management accounts information. Forward-looking statements have been made by the Directors in good faith using information available up until the date that they approved this statement. Forward-looking statements should be regarded with caution because of the inherent uncertainties in economic trends and business risks.
