Executive Summary

Halma PLC represents a high-quality industrial technology conglomerate whose unique, decentralized “Sustainable Growth Model” has enabled a multi-decade track record of resilient, compounding growth in revenue, profit, and dividends. The company’s strength is derived from its portfolio of autonomous businesses, each a leader in a defensible, regulation-driven niche market within the safety, health, and environmental sectors. This structure combines the agility and entrepreneurial focus of small, specialized firms with the financial strength and strategic oversight of a FTSE 100 parent.

The core of Halma’s success lies in its disciplined capital allocation, which prioritizes reinvestment into high-return organic growth initiatives and a programmatic, value-accretive M&A strategy. This dual growth engine is fueled by strong, consistent cash generation, which in turn supports an exceptional 46-year record of increasing dividends by 5% or more annually. The company’s end markets are underpinned by non-discretionary, long-term drivers such as increasing health and safety regulation, resource scarcity, and demographic shifts, which provide a significant degree of resilience through economic cycles.

Key considerations for investors revolve around the company’s persistently premium valuation. Halma consistently trades at a significant premium to the broader market and most industrial peers, a reflection of its superior financial metrics, growth consistency, and defensive characteristics. The central question for investors is whether the current valuation adequately prices in the company’s robust future growth prospects or if it offers a sufficient margin of safety against potential execution risks, such as a slowdown in its M&A engine or a cyclical downturn in specific sub-sectors. This report provides a comprehensive analysis of Halma’s business model, competitive positioning, financial performance, and risk factors to address this fundamental question.

1.0 Company Profile & Sustainable Growth Model

1.1 Core Operations: The Three Pillars of Safety, Health, and Environment

Halma PLC is a global group of nearly 50 life-saving technology companies, headquartered in Amersham, England, and employing over 8,000 people across more than 20 countries.¹ The group’s unifying purpose is to “grow a safer, cleaner, healthier future for everyone, every day,” a mission that defines its strategic focus and the three core market areas in which its subsidiaries operate.²

• Safety Sector: This is Halma’s largest segment, accounting for 40% of revenue in the fiscal year 2025 (FY25).⁴ Its companies provide a wide array of technologies designed to protect people, assets, and infrastructure. Key product areas include fire and smoke detection systems, specialized fire suppression equipment, elevator safety sensors, audible and visual warning devices, and industrial access control systems that ensure the safe operation of critical processes.²
• Environmental & Analysis (E&A) Sector: Representing 35% of FY25 revenue, this sector focuses on technologies that monitor and protect the environment and ensure the quality and availability of life-critical resources.⁴ Its portfolio includes advanced optical, optoelectronic, and spectral imaging systems for material analysis, as well as technologies for water analysis, water treatment, and the monitoring of environmental conditions such as air and gas quality.²
• Healthcare Sector: This segment, contributing 25% of FY25 revenue, delivers technologies that enhance the quality of life for patients and improve the quality of care provided by healthcare professionals.⁴ Its products range from critical fluidic components used in medical diagnostics and life sciences to laboratory devices, health assessment technologies, and therapeutic solutions for ophthalmology and other clinical specialties.²

1.2 The Halma DNA: A Decentralized Model as a Core Competitive Advantage

At the heart of Halma’s long-term success is a unique organizational structure and culture that it refers to as “Halma’s DNA”.⁷ Unlike traditional industrial conglomerates that centralize operations, Halma employs a lean and highly decentralized model built upon three distinct layers: the individual operating companies, the sectors, and the Group executive team.²

Each of the nearly 50 operating companies is managed as an individual legal entity with its own board of directors. A crucial element of Halma’s M&A strategy is that acquired companies retain significant operational autonomy, their brand identity, and their distinct culture.² This structure fosters an entrepreneurial environment, promotes agility by keeping decision-making close to the customer, and instills a strong sense of accountability for performance at the local level.²

The Group’s role is not to micromanage but to provide a robust governance framework, disciplined capital allocation, and strategic support through its “Growth Enablers.” These are small, central teams that offer specialized expertise in critical areas such as international expansion, digital technology, and talent development, which individual companies can leverage to accelerate their growth.⁸ This model has proven to be a powerful “talent and M&A flywheel.” The autonomy offered is a highly attractive proposition for the founders of successful, niche businesses, making Halma an acquirer of choice.⁸ This allows Halma to consistently acquire high-quality, entrepreneurial companies. In turn, the strong cash flow generated by these well-run businesses provides the capital to fund further acquisitions, creating a self-reinforcing and scalable growth cycle that is more sustainable than M&A models based purely on financial leverage or synergy extraction.

1.3 Revenue Characteristics: The Role of Installed Base, Consumables, and Aftermarket Services

While Halma does not report a specific percentage of recurring revenue, a detailed analysis of its business model reveals that its revenue streams are of a higher quality and predictability than a typical industrial company.¹¹ This stability is derived from the mission-critical nature of its products, which creates a large and growing installed base that generates significant follow-on demand for consumables, services, and upgrades.

• Installed Base Dynamics: Many of Halma’s products, once sold, become integral parts of a customer’s safety, compliance, or operational infrastructure. Examples include fire detection systems in commercial buildings, water quality monitoring sensors in municipal networks, and diagnostic instruments in healthcare laboratories. This large installed base creates a captive audience for future sales.¹¹
• Aftermarket & Consumables: The installed base is a powerful driver of aftermarket revenue streams. These are not typically long-term contracts but rather a continuous flow of business driven by operational necessity:

• In the Safety sector, this includes mandatory maintenance contracts, regular inspections, and the sale of replacement parts for fire, security, and industrial safety systems.¹¹
• In the E&A sector, it involves calibration services for analytical instruments, the replacement of sensors with finite lifespans, and increasingly, software subscriptions for data analysis and monitoring platforms.¹¹
• In the Healthcare sector, this is particularly strong, with recurring sales of consumables such as single-use sample collection devices (e.g., Rovers’ products for cervical cancer screening) and sterile, single-use components for surgical instruments like Medicel’s lens injectors.¹¹

This business model creates a form of “de facto recurring revenue.” While not contractually guaranteed in the same way as a software-as-a-service (SaaS) subscription, the demand is highly predictable and non-discretionary, driven by regulatory mandates and the critical function of the products. This results in high customer switching costs and a revenue profile that is significantly more resilient and less cyclical than that of a traditional capital goods manufacturer.¹¹

1.4 Global Footprint and Strategic Market Exposure

Halma’s operations are globally diversified, with major hubs in the UK, Mainland Europe, the USA, and the Asia Pacific region.² This geographic spread provides resilience against regional economic downturns and allows the company to capitalize on growth opportunities in both developed and emerging markets.

The revenue breakdown for FY25 underscores this diversification:

• USA: 46% (£1,039 million)
• Mainland Europe: 19% (£431 million)
• United Kingdom: 14% (£316 million)
• Asia Pacific: 14% (£304 million)
• Other Regions: 7% (£80 million) ⁴

The United States is the company’s largest and one of its fastest-growing regions, representing a key strategic market where stringent safety and environmental regulations create substantial demand for Halma’s technologies.⁵ The continued focus on expanding its presence in the high-growth Asia Pacific region further balances its geographic portfolio.

2.0 Industry Analysis & Competitive Positioning

2.1 Market Dynamics: Sizing the Opportunity in Safety, Health, and Environmental Niches

Halma operates within the broad and growing Environment, Health, and Safety (EHS) market. While definitions and scopes vary, market research reports consistently point to a large and expanding addressable market. Estimates for the global EHS market size in 2024 range from approximately $8 billion to over $52 billion, with consensus forecasts for a Compound Annual Growth Rate (CAGR) of 7.0% to 9.0% through the next decade.¹⁶

This robust growth is underpinned by several powerful, long-term secular trends:

• Increasing Regulatory Scrutiny: Governments worldwide are implementing stricter regulations related to workplace safety, environmental protection, and public health.
• Growing Public and Corporate Awareness: There is a rising emphasis on sustainability, corporate social responsibility, and creating a “zero incident” safety culture.
• Industrialization and Urbanization: Economic development, particularly in emerging markets, drives the need for new infrastructure, manufacturing facilities, and commercial buildings, all of which require safety and environmental solutions.
• Technological Advancement: The adoption of digital technologies, including IoT sensors, cloud-based software, and AI-driven analytics, is creating new opportunities for more advanced and efficient EHS solutions.¹⁶

Geographically, North America represents the largest market due to its mature and stringent regulatory frameworks, such as those enforced by the Occupational Safety and Health Administration (OSHA) and the Environmental Protection Agency (EPA). The Asia Pacific region is forecast to be the fastest-growing market, driven by rapid industrialization and increasing regulatory enforcement in countries like China and India.¹⁶ This market landscape aligns perfectly with Halma’s primary geographic exposures and growth initiatives.¹⁵

2.2 The Regulatory Moat: How Compliance Mandates Drive Resilient Demand

A fundamental pillar of Halma’s business model and a key source of its competitive advantage is the non-discretionary nature of demand for many of its products, which is driven by regulation. Compliance with safety, health, and environmental laws is not an optional expense for Halma’s customers; it is a critical requirement for their license to operate.²¹

Failure to comply with regulations set by bodies like the EPA can lead to severe consequences, including substantial fines, civil and criminal charges, operational shutdowns, and significant reputational damage.²¹ This makes investment in certified safety and monitoring equipment a high-priority, resilient budget item that is less susceptible to cuts during economic downturns compared to discretionary capital expenditures.

This regulatory environment acts as both a shield and a propeller for Halma. It creates a powerful competitive moat (a shield) by establishing high standards and certification requirements that are difficult and costly for new entrants to meet.¹¹ At the same time, the continuous evolution and tightening of these regulations globally acts as a perpetual demand driver (a propeller), compelling customers to upgrade existing systems or invest in new technologies to remain compliant, thereby fueling Halma’s organic growth.

2.3 Barriers to Entry: The Power of Technology, IP, and Customer Relationships

Halma’s strategy of focusing on specialized, global niche markets means its operating companies are protected by significant and sustainable barriers to entry.¹¹ These moats are built on three key foundations:

• Proprietary Technology and Intellectual Property: Halma’s companies are technology leaders in their respective fields, possessing deep application knowledge and often protected by patents. The Group’s sustained high investment in research and development—5.3% of revenue in FY24, for example—ensures a continuous pipeline of innovation, creating a constantly moving target for would-be competitors.¹¹ A prime example is Medicel, described as a global market leader whose innovative lens injector technology is used in a significant portion of all cataract surgeries worldwide, demonstrating a unique and defensible technological position.¹¹
• Regulatory Approvals and Certifications: Gaining the necessary certifications to sell products into safety-critical or healthcare markets is a formidable barrier. The process is often lengthy, complex, and expensive, requiring extensive testing and documentation. For instance, products from Halma’s subsidiary Lazer Safe hold a “SIL 3” (Safety Integrity Level 3) certification from the International Electrotechnical Commission, which is one of the highest safety ratings available and represents a significant hurdle for new competitors to overcome.¹¹
• Strong Customer Relationships and High Switching Costs: The decentralized model empowers Halma’s companies to build intimate, long-term partnerships with their customers.¹¹ Because the products are often mission-critical—ensuring worker safety, preventing environmental disasters, or enabling accurate medical diagnoses—customers place a high value on reliability, quality, and service. This creates a strong ” incumbency advantage” and high switching costs, as customers are reluctant to risk operational disruption or non-compliance by switching to a new or unproven supplier.

2.4 Competitive Landscape: A Fragmented Field of Specialists and Conglomerates

The competitive environment for Halma is highly fragmented. The Group does not face a single, direct competitor across its entire portfolio. Instead, each of its ~50 operating companies competes within its specific niche against a handful of other specialists or the specialized divisions of larger industrial conglomerates.²⁹

• Safety Sector Competitors: In fire detection, Halma’s subsidiary Apollo Fire Detectors competes with divisions of large industrial players like Johnson Controls, Honeywell International, and Siemens AG, as well as focused specialists such as Gentex Corporation and Hochiki.³⁰ In gas detection, its Crowcon business competes with firms like MSA Safety, Drägerwerk, and Teledyne Technologies.³⁴
• Environmental & Analysis Sector Competitors: In optical analysis, Ocean Insight faces competition from photonics equipment manufacturers like Thorlabs and Hamamatsu Photonics.³⁷ In water analysis, Palintest competes with companies such as In-Situ and LaMotte.³⁹
• Healthcare Sector Competitors: In the ophthalmic lens market, Volk Optical’s main competitors include specialized surgical instrument makers like Katena and Ocular Instruments.⁴³ In blood pressure monitoring technology, SunTech Medical competes with divisions of large medical technology firms like GE HealthCare, Philips, and Medtronic, as well as specialists like Omron Healthcare.⁴⁶

At the group level, Halma’s most relevant peers are other diversified industrial technology companies that employ a similar strategy of acquiring and managing a portfolio of high-margin, niche businesses. This peer group includes UK-based companies like Spectris plc and Renishaw plc, and US-based conglomerates like AMETEK, Inc. and Danaher Corporation.⁴⁹ Halma’s “anti-conglomerate” approach to building its conglomerate is a key differentiator. While traditional conglomerates often suffer from a valuation discount due to complexity and a lack of synergies, Halma avoids this by acting primarily as a disciplined capital allocator and strategic guide for its portfolio of agile, independent specialists. This structure allows it to capture the benefits of diversification (financial resilience, pooled resources) without stifling the entrepreneurial culture and customer focus that are essential for success in its niche markets.

3.0 Financial Performance Analysis (FY 2022-2025)

Halma’s financial performance over the 2022-2025 fiscal period demonstrates the resilience and power of its Sustainable Growth Model. The company has delivered consistent growth in revenue and profits, maintained its structurally high margins, and generated strong cash flows, all while navigating a challenging macroeconomic environment characterized by supply chain disruptions, inflation, and currency volatility.³

3.1 Revenue Trajectory: Deconstructing Growth

Halma has shown an impressive and consistent ability to grow its top line, surpassing £2 billion in revenue for the first time in FY24 and reaching £2.25 billion in FY25.⁵²

• FY22 Revenue: £1,525.3 million (+16%) ⁵
• FY23 Revenue: £1,852.8 million (+21%) ⁵⁴
• FY24 Revenue: £2,034.1 million (+10%) ³
• FY25 Revenue: £2,248.1 million (+11%) ⁵²

This growth is achieved through a balanced combination of organic initiatives and strategic acquisitions. Organic constant currency (OCCY) growth has been robust, at +10% in FY23, +8% in FY24, and +9% in FY25.⁵² Acquisitions have consistently supplemented this, contributing 5.0% to revenue growth in FY24 and 3.1% in FY25.⁵³

Performance has been broad-based across segments, though with some variation. FY24 saw strong growth in the Safety and E&A sectors, which more than compensated for a temporary decline in the Healthcare sector.⁵³ In FY25, this pattern continued with strong performances from Safety (+9.5%) and E&A (+18.0%), the latter benefiting from exceptional performance in its photonics businesses. The Healthcare sector returned to modest growth (+3.2%) following a substantial improvement in the second half of the year.⁵²

3.2 Profitability & Returns Analysis: A Study in Resilience

A hallmark of Halma’s financial profile is its ability to generate not just growth, but highly profitable growth. As of FY25, the company has achieved an extraordinary 22 consecutive years of record adjusted profit growth.⁵²

• Adjusted Profit Before Tax (PBT) Growth:

• FY22: £316.2 million (+14%) ⁵
• FY23: £361.3 million (+14%) ⁵⁴
• FY24: £396.4 million (+10%) ³
• FY25: £459.4 million (+16%) ⁵²

This consistent profit growth is underpinned by structurally superior margins and returns on capital, which are a direct result of the company’s strategic focus on high-value, technology-driven niches with limited competition and strong pricing power.

• Adjusted EBIT Margin: Halma consistently operates within its target range of 19-23%.⁵² The margin was 20.7% in FY22, dipped slightly to 20.4% in FY23 amid supply chain pressures, recovered to 20.8% in FY24, and expanded significantly to 21.6% in FY25, reflecting strong operational execution and favorable product mix.⁵
• Return on Total Invested Capital (ROTIC): This is a key measure of the quality of Halma’s business model and capital allocation. The company consistently generates returns well in excess of its 12% target and its weighted average cost of capital (WACC) of approximately 9.8%.⁵² ROTIC stood at 14.6% in FY22, 14.8% in FY23, 14.4% in FY24, and rose to 15.0% in FY25.⁵

The following table summarizes key financial and performance metrics for the past four fiscal years, illustrating the company’s consistent and high-quality financial performance.

Metric	FY2022	FY2023	FY2024	FY2025
Revenue (£m)	1,525.3	1,852.8	2,034.1	2,248.1
Revenue Growth (%)	16%	21%	10%	11%
Organic Revenue Growth (OCCY, %)	18.2%	10%	8%	9%
Adj. EBIT (£m)	333.5	378.2	424.0	486.3

3.3 Cash Flow Engine: Analysis of Cash Conversion and Working Capital

Halma’s business model is highly cash-generative, a key attribute that funds its dual growth strategy. The company targets cash conversion—defined as adjusted operating cash flow as a percentage of adjusted operating profit—of over 90%.⁵²

Performance against this target highlights both the underlying strength of the business and the quality of its management. In FY23, cash conversion dipped to 78%.⁵⁴ This was not a sign of weakness, but rather a deliberate strategic decision by management to invest in inventory to build resilience against global electronic component shortages.⁵⁵ This willingness to prioritize long-term operational stability over short-term adherence to a KPI is a mark of a confident and forward-thinking leadership team. The subsequent powerful rebound in cash conversion to 103% in FY24 and an exceptional 112% in FY25 demonstrates that the working capital build was temporary and that the underlying cash-generating power of the business remains robust.⁵²

3.4 Balance Sheet Strength and Financial Flexibility

Halma maintains a strong and flexible balance sheet as a strategic imperative to support its active M&A program. The company’s leverage policy is conservative, with a stated operating range for net debt to EBITDA of up to 2.0x.⁵²

At the end of FY23, following a year of significant acquisition spend, leverage stood at 1.38x, comfortably within the target range.⁵⁴ This remained stable at 1.35x at the end of FY24.⁵³ The strength of the company’s cash generation is evident in the reduction of leverage to just 0.97x by the end of FY25, even after further investment in acquisitions.⁵² This strong deleveraging capacity provides Halma with substantial financial “firepower and flexibility” to continue executing its M&A strategy without straining its financial position.⁵⁷

4.0 Growth Strategy & Capital Allocation Framework

4.1 The Dual Growth Engine: Organic Innovation (R&D) and Strategic M&A

Halma’s growth strategy is built on a clear and ambitious objective: to double its revenue and profit every five years.²³ This goal is pursued through a balanced, dual-engine approach that combines steady organic growth with disciplined, strategic acquisitions.

• Organic Growth: The foundation of Halma’s long-term value creation is its commitment to organic growth, driven primarily by innovation. The company consistently invests a high proportion of its revenue back into Research & Development (R&D) to maintain its technological leadership, develop new products, and expand into adjacent markets. R&D expenditure as a percentage of revenue was 5.5% in FY23, 5.3% in FY24, and 4.8% in FY25, consistently exceeding the Group’s internal KPI target of over 4%.¹¹ This sustained investment is not just a line item on the income statement; it is a critical component of widening the company’s competitive moats and ensuring the long-term relevance of its products.¹¹
• M&A Growth: Acquisitions are the primary engine for step-change growth and a core competency of the Group. The strategy is not to pursue large, transformative deals, but rather to programmatically acquire small- to medium-sized technology companies that are leaders in high-value, global niches.⁸

4.2 A Disciplined Acquirer: M&A Strategy, Execution, and Value Creation

Halma’s success in M&A is rooted in a highly disciplined and repeatable process, from target identification to post-acquisition management.

• Acquisition Criteria: The M&A team maintains a strict set of criteria. Targets must be closely aligned with Halma’s purpose, operate in global niche markets with long-term growth drivers, possess strong financial characteristics (high margins and returns), and, crucially, have a compatible entrepreneurial culture.⁵⁷
• Integration and Value Creation: Halma’s post-acquisition model is a key differentiator. Upon closing a deal, the Divisional Chief Executive from the relevant Halma sector becomes the Chair of the newly acquired business, ensuring immediate strategic alignment and access to Group resources. However, the business retains its brand, its leadership team, and significant operational autonomy.⁸ This approach has proven highly effective at retaining the entrepreneurial talent and culture that made the business successful in the first place, while providing the capital and strategic support to accelerate its growth. The acquisitions are not just about buying revenue; they are strategic moves to acquire new technologies, enter adjacent markets, and expand geographic reach, thereby widening the moat of the entire Group.
• Recent M&A Activity: The company has maintained a steady pace of acquisitions through the 2022-2024 period, demonstrating the health of its acquisition pipeline. The following table summarizes key transactions.

Fiscal Year	Acquired Company	Business Description	Sector	Max. Consideration
FY23	IZI Medical Products	Medical devices for diagnostics & treatment	Healthcare	£138m
FY23	WEETECH	Test systems for cables & electronics	Safety	€57.5m
FY24	FirePro	Aerosol-based fire suppression systems	Safety	€150m
FY24	TeDan	Surgical access systems	Healthcare	$90m
FY24	Sewertronics	Trenchless pipeline rehabilitation tech	E&A	€41m
FY24	Lazer Safe	Press brake safety technology	Safety	A$45m
FY25	MK Test Systems	Electrical wiring test systems	Safety	£44m
FY25	Lamidey Noury Medical	Electrosurgical instruments	Healthcare	€50m

Note: Data compiled from multiple sources.⁸ This is not an exhaustive list.

A consistent feature of these deals is that the target companies are highly profitable, often with a Return on Sales “substantially above” Halma’s own target range of 18-22%, making them immediately accretive to the Group’s financial profile.⁵⁸

4.3 Capital Allocation Priorities: Balancing Reinvestment with Shareholder Returns

Management adheres to a clear and consistent capital allocation hierarchy that prioritizes long-term value creation ⁵⁷:

1. Organic Investment: The first call on capital is always to fund organic growth opportunities, primarily through R&D and capital expenditures.
2. Value-Enhancing M&A: The primary use of surplus cash flow is to fund the disciplined acquisition strategy.
3. Progressive Dividends: A commitment to returning a growing stream of cash to shareholders through a progressive dividend policy.

Notably, share buybacks are not a stated priority in the capital allocation framework. Capital is overwhelmingly directed towards investments intended to drive future growth.⁵⁷

4.4 Dividend Aristocracy: A Multi-Decade Track Record

Halma’s dividend policy is a cornerstone of its investment case and a powerful signal of the Board’s confidence in the long-term sustainability of its business model. As of the end of FY25, the company has achieved an exceptional 46 consecutive years of dividend growth of 5% or more.⁵²

The dividend per share has consistently grown by 7% annually in each of the last four fiscal years (FY22-FY25), reflecting the Board’s unwavering confidence in the Group’s future prospects.⁵ The dividend is managed prudently, with a conservative payout ratio that ensures it is well-covered by earnings and does not compromise the company’s ability to reinvest for growth.⁶⁵ This multi-decade track record can only be achieved through decades of consistent, profitable growth through multiple economic cycles. It imposes a strong discipline on management’s capital allocation decisions, as they must ensure that all investments generate sufficient returns to sustain this remarkable streak.

5.0 Valuation Assessment

Halma’s long-term track record of superior growth and profitability has resulted in the market consistently awarding the company a premium valuation relative to the broader industrial sector. The key consideration for any potential investment is whether this premium is justified by the quality and sustainability of its earnings and growth prospects.

5.1 Historical and Current Valuation Multiples in Context

An analysis of Halma’s valuation multiples reveals a consistent and significant premium:

• Price-to-Earnings (P/E) Ratio: As of mid-2025, Halma’s trailing P/E ratio is in the range of 41x to 45x.⁶⁶ This is consistent with its recent history, where the P/E has typically fluctuated between 35x and 47x over the 2020-2024 period.⁶⁹ The 10-year average P/E of approximately 35x indicates that this premium is not a recent development but rather a long-standing feature of the stock’s valuation.⁶⁷
• Enterprise Value-to-EBITDA (EV/EBITDA) Ratio: This multiple, which is independent of capital structure, also reflects a premium valuation. In mid-2025, the ratio stands at approximately 24x to 25x.⁷¹ Over the past five years, this metric has ranged from a low of 22.0x to a high of 30.7x, reinforcing the persistent premium.⁷¹

5.2 Peer Group Benchmarking: Justifying the Premium

When benchmarked against its closest peers in the industrial technology space, Halma’s valuation is at the upper end of the spectrum. However, its financial performance metrics are also demonstrably superior.

Metric	Halma PLC	Danaher (DHR)	AMETEK (AME)	Spectris (SXS)	Renishaw (RSW)	Industrials Sector Avg.
P/E Ratio (TTM)	~41.3x	~44.3x	~29.2x	~27.2x	~22.4x	~27.9x
EV/EBITDA (TTM)	~23.9x	~21.6x	~19.7x	N/A	N/A	~16.7x
Adj. EBIT Margin (%)	21.6%	~18.2%	25.9%	~14.3%	~16.4%	N/A
ROTIC/ROIC (%)	15.0%	N/A	9.1%	N/A	N/A	N/A
5-Yr Revenue CAGR	10.9%	N/A	N/A	N/A	3.8%	N/A

Note: Data compiled from multiple sources.⁵¹ Peer data is based on the latest available information from the sources and may not be for the exact same period as Halma’s FY25 data. Sector averages are indicative.

The comparison highlights that while Halma’s multiples are high, they are not entirely out of line with Danaher, which is arguably its closest strategic peer. Both companies employ a similar M&A-led compounding model and focus on high-margin, defensive niches. Danaher’s long-term success and sustained premium valuation provide a compelling precedent and a potential roadmap for Halma’s own valuation trajectory. The data also clearly shows that Halma’s profitability (EBIT Margin) and returns on capital (ROTIC) are at the top end of the peer group, providing a fundamental justification for its premium valuation.

5.3 Key Valuation Drivers and Forward-Looking Considerations

The market’s willingness to pay a premium for Halma’s shares is driven by a clear set of factors:

1. Exceptional Consistency: The multi-decade track record of uninterrupted profit and dividend growth provides a high degree of earnings visibility and predictability.
2. Superior Profitability: The structurally high and stable margins and returns on capital are characteristic of a high-quality business with strong competitive advantages.
3. Proven Growth Model: The repeatable M&A engine provides a clear path to future growth that is less dependent on the broader economic cycle.

Despite the high multiples, Halma can be viewed through a “Growth at a Reasonable Price” (GARP) lens, where the “reasonableness” of the price is justified by the exceptional and defensible quality of the underlying business. The investment decision is less about whether the P/E ratio is high in absolute terms, and more about whether the business can continue to execute and sustain the superior fundamental performance that commands such a premium. Analyst consensus forecasts remain positive on future earnings growth, with a median 12-month price target of approximately 3,250p, suggesting that at current levels, the stock is largely considered to be fairly valued.⁶⁵

6.0 Risk Assessment & Recent Headwinds

6.1 Analysis of Principal Risks

Halma’s annual report provides a comprehensive overview of the principal risks facing the Group, which are actively managed within the company’s risk appetite.¹¹

• Strategic Risks:

• Talent Management: The decentralized model is highly dependent on attracting and retaining exceptional, entrepreneurial leaders for its operating companies. A failure in succession planning or talent development could undermine the model’s effectiveness.
• Innovation: In a technology-driven business, failing to innovate and keep pace with technological change could lead to a loss of competitive advantage.
• M&A Execution: The M&A strategy is central to growth. A poorly executed or overpriced acquisition, or a slowdown in the ability to find suitable targets, could significantly impact future growth and returns.
• Economic & Geopolitical Uncertainty: As a global business, Halma is exposed to macroeconomic downturns and political instability. This risk is mitigated by the geographic and end-market diversity of its portfolio.
• Operational Risks:

• Cybersecurity: The increasing digitalization of products and operations creates a very high inherent risk of cyber-attacks, which could lead to business interruption, data loss, and reputational damage.
• Supply Chain Disruption: As demonstrated in recent years, disruption in the supply of critical components (particularly electronics) can impact production, increase costs, and constrain profitability.
• Financial Risks:

• Currency Translation: With a significant portion of its revenue and profit generated in US dollars and euros, the strengthening of Sterling against these currencies creates a negative translational headwind on reported results.⁵⁵
• Liquidity and Funding: This risk is considered low due to Halma’s strong cash generation and conservative balance sheet management.

While external macroeconomic and geopolitical factors are significant, Halma’s diversified and resilient business model provides a substantial buffer. The most critical long-term risk is arguably internal: a failure of execution. A deviation from the disciplined culture of capital allocation and operational excellence, such as a single large and poorly integrated acquisition, could potentially do more damage to long-term shareholder value than a general economic recession.

6.2 Navigating Macro Headwinds (2022-2024)

Halma’s performance through the recent period of global volatility provides a real-world stress test of its business model:

• Supply Chain Disruptions: In FY23, the company was directly impacted by shortages of electronic components. Management responded proactively by making a strategic investment in inventory to ensure security of supply. This decision temporarily reduced cash conversion but protected revenue and customer relationships, demonstrating a prudent long-term approach.⁵⁵ By FY24, these pressures had largely eased.
• Inflation: The inflationary spike in input costs was managed effectively through Halma’s strong pricing power. In FY23, price increases contributed approximately four percentage points to revenue growth, successfully offsetting the majority of cost increases.⁵⁵ This ability to pass on costs is a clear testament to the value customers place on its critical products.
• Currency Fluctuations: The volatility of Sterling has had a notable impact on reported results. The weakness of Sterling in FY23 provided a significant tailwind, boosting reported revenue by 8.1%.⁵⁵ Conversely, the strengthening of Sterling in FY24 and FY25 created a translational headwind. In FY25, currency movements had a negative impact of 1.6% on revenue and 1.9% on EBIT. Management has guided for a potential headwind of around 4% in FY26 based on current exchange rates.¹¹

7.0 Management & Corporate Governance

7.1 Leadership Team Assessment and Track Record of Execution

Halma’s leadership team is characterized by a blend of long-tenured internal experience and external expertise, ensuring both strategic continuity and fresh perspectives.

• Group Chief Executive, Marc Ronchetti: Appointed in April 2023, Mr. Ronchetti represents a seamless internal succession, having served as the Group Chief Financial Officer since 2018. His tenure as CFO was marked by strong financial performance and the successful execution of numerous acquisitions, indicating a deep understanding of Halma’s Sustainable Growth Model and capital allocation discipline.⁸⁶ This promotion of the CFO to CEO is indicative of a strong succession planning process and a culture that develops its leaders internally, which is crucial for preserving the unique “Halma DNA.”
• Chief Financial Officer, Carole Cran: Appointed in April 2025, Ms. Cran was previously a non-executive director on Halma’s board since 2016. She brings extensive external financial leadership experience from her roles as CFO of Aggreko plc and Forth Ports Limited, providing a valuable external perspective to the executive team.⁸⁶
• Board of Directors: The Board is led by an independent Chair, Dame Louise Makin, and is composed of a majority of independent non-executive directors. The directors bring a diverse range of experience from relevant sectors, including technology, healthcare, finance, and international business.⁸⁸

The ultimate testament to the management team’s and the Board’s long-term track record of execution is the company’s exceptional financial history, highlighted by 22 consecutive years of profit growth and 46 consecutive years of dividend growth of 5% or more.⁵²

7.2 Governance Structure and Alignment with Shareholder Interests

Halma adheres to high standards of corporate governance, reporting full compliance with the UK Corporate Governance Code 2018.⁸⁹

• Insider and Institutional Ownership: As is common for a large FTSE 100 company, direct insider ownership by executives is relatively low (CEO ownership is approximately 0.043%).⁸⁸ However, institutional ownership is high, at around 56%, indicating strong support from professional investors who are typically focused on long-term value creation.⁶⁶
• Remuneration Policy: Executive remuneration is strongly aligned with performance and strategic objectives. Since 2023, long-term incentive plans have incorporated non-financial sustainability targets, including progress on carbon emissions reduction and gender balance on company boards, alongside traditional financial metrics. This ensures that management is incentivized to deliver sustainable, long-term growth for all stakeholders.⁹³

8.0 Investment Thesis Synthesis

8.1 Answering Key Questions

• How resilient is Halma’s business model during economic downturns? The model is exceptionally resilient. This is due to its diversification across multiple non-correlated end-markets and geographies, the non-discretionary demand for its products driven by safety and environmental regulation, and its conservative balance sheet. Its multi-decade track record of uninterrupted profit and dividend growth through numerous economic cycles provides empirical evidence of this resilience.
• What is the quality and sustainability of the company’s growth? The quality of growth is very high. It is driven by a balanced and proven combination of defensible organic growth, fueled by high R&D investment in protected niches, and a disciplined, value-accretive M&A program. This growth is sustainable due to its alignment with long-term, structural market tailwinds, including increasing regulation, resource scarcity, and demographic shifts.
• How effective has management been at capital allocation, particularly M&A? Management’s capital allocation has been excellent. The 46-year track record of growing the dividend by over 5% annually imposes a powerful discipline, ensuring that all investments—both organic and acquired—must meet high return hurdles. The M&A program has been a clear success, consistently adding high-quality, high-margin businesses that strengthen the Group’s competitive moats.
• What are the most significant risks that could impair future returns? The most significant risk is internal execution. A departure from the disciplined M&A and operational culture that has been the foundation of its success, such as a large, poorly integrated acquisition, poses a greater threat than external macroeconomic factors. The stock’s premium valuation is also a key risk, as any perceived slowdown in growth could lead to a significant de-rating of its valuation multiples.
• How does the current valuation reflect the business quality and growth prospects? The current premium valuation fully reflects the market’s appreciation for Halma’s exceptional business quality, its consistency, and its reliable growth prospects. It prices in a high degree of continued success and offers a limited margin of safety for any potential execution missteps or a slowdown in its growth trajectory.

8.2 The Balance of Quality, Growth, and Valuation: Factors for an Investment Decision

Halma PLC stands out as a “best-in-class” industrial compounder, offering a rare combination of defensive characteristics and sustainable long-term growth.

Factors that make Halma an attractive investment opportunity include:

• An unquestionable high-quality business with a portfolio of market-leading niche technology companies.
• A proven and repeatable “Sustainable Growth Model” that has delivered exceptional returns for decades.
• Exposure to defensive end-markets underpinned by powerful, long-term structural growth drivers.
• An outstanding track record of disciplined capital allocation and shareholder value creation, exemplified by its 46-year dividend growth streak.
• A strong, flexible balance sheet that provides the firepower for continued M&A-led growth.

Factors that make Halma a potentially unattractive investment opportunity at current levels include:

• A persistently premium valuation that is at the high end of its historical range and its peer group, offering little margin of safety.
• Inherent exposure to foreign currency fluctuations, which can create headwinds for reported earnings.
• The ever-present risk that its highly successful M&A engine could slow down due to a lack of suitable targets or that a future acquisition could be poorly executed.

In conclusion, for long-term investors with a focus on quality and a willingness to pay a premium for predictable, compounding growth, Halma PLC represents a compelling core holding. The investment decision ultimately hinges on an investor’s comfort level with the current valuation and their confidence in the ability of Marc Ronchetti and his team to continue executing the company’s proven strategy with the same discipline and success that has defined it for the past half-century.
