What Halma does

Halma plc is a UK-headquartered FTSE 100 holding company that owns and operates more than 50 wholly-owned subsidiaries specializing in safety, environmental and analysis, and healthcare technologies. Its portfolio spans fire detection systems (Apollo, Ampac, E2S, FirePro, Firetrace), gas detection (Crowcon, SENSIT), electrical testing and laser safety (WEETECH, Lazer Safe, MK Test), water quality and pipeline inspection (Palintest, Minicam Group, Deep Trekker, HWM Global), photonics and scientific instruments (Ocean Optics, Avo Photonics, Alicat), and a broad medical device franchise covering ophthalmology (Keeler, Volk Optical, MST), blood pressure monitoring (SunTech), image-guided surgery and interventional oncology (IZI Medical, Lamidey Noury), cervical cancer screening (Rovers), real-time location systems (CenTrak), and respiratory care (Salaera). Products are predominantly regulated, mission-critical hardware with associated consumables, sensors, and services.

The group runs a decentralized operating model: each subsidiary retains its own brand, leadership, and sales force while benefiting from Halma's capital allocation, acquisition pipeline, and cross-portfolio best practice. Customers are B2B and span healthcare providers (roughly 2,500 US hospitals for IZI Medical), industrial operators in oil and gas, power generation, pharmaceuticals, renewable energy, semiconductor, water utilities, and hyperscale data centers. Revenue is generated primarily through one-time hardware sales augmented by recurring sensor, consumable, and service revenue streams tied to mandatory replacement cycles and long-term customer relationships.

Halma's growth model is acquisition-driven on top of organic compounding. The company has completed more than 50 acquisitions over its history, including five in FY2025/26 alone (E2S £230m, Brownline €150m, Safetec €72.5m, Surgistar ~$90m, Nu Perspectives £1.5m). In FY2025/26 the group reported revenue of £2,582.3 million (+15%), adjusted EBIT of £594.5 million (+22%), and a 16.2% Return on Total Invested Capital, marking 23 consecutive years of record adjusted profit and 47 consecutive years of dividend growth of 5% or more. The company's investment case rests on regulatory tailwinds in safety, healthcare, and environmental markets; demographic and energy-transition megatrends; and disciplined bolt-on M&A into defensive niches.

Direct peers

• Spectris plc: UK-listed diversified group of high-precision instrument and sensing businesses (HBK, Omega, Red Lion, Malvern Panalytical). Closest structural and end-market peer to Halma — similar acquisition-led compounding model, similar niche industrial positioning, similar regulatory tailwinds.
• IDEX Corporation: US-listed holding company of highly engineered fluidics, dispensing, and health/science niche businesses. Similar decentralized operating model and comparable end-market mix (industrial, life sciences, fire & safety).
• Ametek Inc. US-listed electronic instruments and electromechanical devices group with strong positions in process measurement, analytical instruments, and engineered solutions. Closely comparable to Halma's Environmental & Analysis segment (Alicat, Ocean Optics, Avo Photonics).
• MSA Safety Incorporated: US-listed pure-play safety equipment manufacturer (fixed gas/flame detection, breathing apparatus, fall protection, fire service helmets). Direct competitor to Halma's Crowcon, E2S and Safetec in industrial safety.
• Drägerwerk AG: German safety and medical technology group focused on gas detection, fire service equipment, and patient monitoring. Direct overlap with Halma's Crowcon gas detection, fire safety, and SunTech/PeriGen medical segments.

Broad incumbents

• Honeywell International: US-listed industrial conglomerate with significant gas detection, fire systems, and sensing businesses (part of the Productivity Solutions and Industrial Automation segments). A scaled incumbent competing with Halma's Safety sector across multiple niches.
• Roper Technologies: Large-cap US diversified niche technology compounder with vertical market software and engineered products. Similar capital-allocation philosophy to Halma — long-hold niche acquisitions with high recurring revenue — but materially larger and more software-skewed.
• Fortive Corporation: US-listed diversified industrial technology group (intelligent operating solutions, precision technologies, advanced healthcare solutions). Comparable operating model with multiple specialist operating companies serving regulated end markets.
• Atlas Copco AB: Swedish industrial group with compressor, vacuum, power and assembly-solutions divisions serving manufacturing, process industries, and infrastructure. Overlaps with Halma's industrial safety / monitoring end markets and shares the compounder-through-acquisition DNA.

Emerging players

• Halma Holdings competitor - Xylem Inc. US-listed water technology company (meters, treatment, analytics). Comparable to Halma's water quality and pipeline inspection businesses (Palintest, Minicam, Deep Trekker, HWM Global) but with a much larger and more consolidated footprint in municipal water.
