Aoris International Fund Matthew Berry | “Halma is a group of niche technology companies focused on safety, health and environmental applications, where its growth is supported by rising safety and environmental standards and regulations. AI has created a major opportunity in one of Halma's businesses, which sells optical technology to a single large data centre customer. Halma acquired this business for less than £6 million in 2011. In the most recent financial year it generated £520 million of revenue, or around 20% of the group. Management expect it to grow by another 30% in the coming year. The manager has decided to limit the company's position size in the portfolio to moderate the impact of concentration risk.” | NEUTRAL | Q2 2026 Jul 23, 2026 | View Pitch |
Fairlight Global Small & Mid Cap Fund Nicholas Cregan | “Halma owns over 50 specialised manufacturers operating in global niches within the safety, environmental and healthcare sectors. The group has compounded EPS at 15% annually for over four decades with low variability due to three key elements: 1. Exposure to structurally growing markets combined with a relentless focus on only differentiated products; 2. A repeatable low-risk M&A strategy guided by strict returns on capital hurdles; and 3. A sustainable approach to financing growth, with minimal debt and no reliance on new equity. One of Halma's many businesses is Avo Photonics, which contributes to the great majority of the group's photonics revenues. Avo has built a relationship of more than a decade with a large hyperscale technology customer, co-designing and manufacturing optical switches critical to data centre infrastructure. In the financial year ended March 2026, Halma's photonics business grew 52%, contributing half of the group's exceptional 16% organic revenue growth. The photonics business now accounts for 20% of group sales, up from 15% last year and 12% the year before. CEO Marc Ronchetti made it clear that Halma is not treating the photonics windfall as a signal to accelerate expansion within this fast-growing but narrow market. Instead, the cash flows are being used to strengthen the whole group. Management has been candid about the limits of this growth. They've been explicit that photonics' growth profile differs from that of the wider group in pace, scale, and longevity, and may cause group-level growth to become more front-end loaded. The premium cash flows from photonics are being directed primarily into R&D and acquisitions in sectors that are currently out of the spotlight, where valuations remain reasonable. Halma has been appropriately cautious about guiding for 30% photonics growth in the coming year, well below the 52% delivered in 2026, and consciously based on near-term order visibility rather than extrapolation of hyperscaler capex announcements. On the central question of whether management is behaving in the way that the evidence suggests preserves long-run value, resisting the empire-building temptation, maintaining capital discipline, and refusing to mistake a cyclical tailwind for a structural shift in the group's ambitions, our judgement is that they are passing the test, and the company remains a key holding in the Fund.” | BULL | Q2 2026 Jul 17, 2026 | View Pitch |
Aoris International Fund Matthew Berry | “Based in the UK, Halma is a leading global supplier of specialty products used in three broad end markets – safety, environmental, and health care. Halma focuses on growing niches within these broad markets, such as gas and flame detectors used in manufacturing facilities, and sensors, radars and emergency communication systems that are used in elevators and car parks, and on motorways. In the environmental sphere, among its many products and solutions are air- and water-quality testing products, and devices that detect leaks in a municipal water system. For Halma, 2025 was another successful year, with its earnings growing by about 15%. While Halma is a highly diversified business, it also has an optical technology business that serves the data centre market, which has experienced exceptional growth in the last couple of years. Even without this tailwind, the rest of Halma grew at an impressive rate in 2025. BSD Analysis: Halma is industrial compounding disguised as a safety and measurement portfolio. Its businesses sell mission-critical sensors and systems where failure carries real consequences. Decentralized operations allow steady innovation without integration risk. Growth is incremental but highly reliable, which is the point. Investors underestimate how regulation and safety standards entrench incumbents. Margins stay resilient because customers buy outcomes, not products. This is risk mitigation monetized quietly over decades.” | BULL | Q4 2025 Dec 31, 2025 | View Pitch |
Aoris International Fund Matthew Berry | “Halma specializes in safety, environmental, and medical niche products with a robust culture of consistent dividend increases. Its emphasis on customer value and sustainable investment has driven double-digit earnings growth.” | BULL | Q4 2024 Dec 31, 2024 | View Pitch |
