Why Invest?

Key pieces of information about the business that you need to know about.

Energy Demand and Decarbonisation

IMI’s Process Automation business benefits from rising global energy demand and the shift toward cleaner sources. Its valves and control systems are critical in gas, LNG, and nuclear power infrastructure, both in new builds and the high-margin aftermarket. The nuclear sector is seeing renewed investment, supported by energy security needs and electrification. Demand linked to data centres and power generation is also increasing, creating new growth opportunities. The division generates ~60% of revenue from aftermarket, with margins 2.5x higher than new construction, and a strong installed base that creates long-duration recurring revenues.

Structural Automation Upside

Industrial and Process Automation represent 64% of group sales, placing IMI at the heart of long-term trends in robotics, manufacturing digitisation, and industrial efficiency. Its technologies are embedded across sectors, from semiconductors to clean energy and infrastructure. While demand remains soft in the short term, order books in Process Automation are strong, supporting a recovery as investment cycles improve. Digitalisation and reshoring continue to create new demand pockets, and IMI’s focus on innovation and high-value applications positions it to capture this recovery.

Proven Compounding Model

IMI's OneIMI operating model is a proven engine of productivity and innovation. The group has improved operating margins from 14% to 20%+, driven by simplification, pricing discipline, and operational improvements. Growth Hub orders have increased to a record £206m, and bolt-on M&A has delivered strong returns. IMI targets 5% organic revenue growth, 90% cash conversion, and 12% ROIC, all within a disciplined capital allocation framework. These targets are now being met or exceeded, with 2025 cash conversion at 96%, ROIC at 14.0%, and free cash flow of £290m. The group is returning capital through a £500m share buyback and a 10% dividend increase, while continuing to invest for growth, supporting long-term compounding.

Key Risks

Key pieces of information about the business risks that you need to know about.

Cyclical Weakness in Industrial Markets

While IMI is well positioned for the automation megatrend, short-term demand across industrial sectors remains soft, especially in Europe and North America. Its Industrial Automation division has shown minimal growth recently, and recovery has been slower than expected. A delayed rebound in capital investment cycles could weigh on overall revenue momentum and dampen operating leverage. Prolonged sluggishness would also test management's ability to maintain margin discipline in the face of fixed costs and uncertain demand.

Execution in Transport Turnaround

IMI’s Transport division, which accounts for roughly 8% of group revenues, is undergoing a multiyear restructuring plan. The goal is to enhance margins, reduce working capital intensity, and exit lower-return product lines. While progress has been made, the segment is still vulnerable to regional truck cycle swings, particularly in the U.S. and Europe. If macro weakness persists or if operational milestones are missed, the recovery could be delayed, undermining return on capital and distracting management focus from higher-return areas of the business.

Macro and FX Sensitivities

With a global footprint spanning 50+ countries, IMI’s earnings are exposed to currency volatility, especially GBP vs USD and EUR. Foreign exchange headwinds can affect both reported revenue and operating profit, particularly when global macro conditions diverge. Additionally, IMI’s exposure to cyclical end-markets makes it vulnerable to broader macro shocks, including supply chain disruptions, inflation, and geopolitical instability. While hedging policies are in place, material FX swings or supply chain cost inflation could compress margins and reduce forecast visibility.

Research on demographics mostly looks at the perils of a shrinking labour force on economic growth but ignores what automation and artificial intelligence does for productivity. Likewise, research on automation and AI focuses on jobs that may be lost, but overlooks the demographic issues they may solve. Put the two together — ageing populations with automation/AI — and there are clusters of investment opportunity.

What the Pros are asking

Here are the questions that professional investors are asking before making an investment decision.

What’s the growth outlook for Process Automation beyond 2025?

Investors want clarity on whether the current momentum in Process Automation is a one-off or a durable growth path. Management has emphasised that the long-cycle nature of the division provides forward visibility, with the installed base and repeat aftermarket orders anchoring growth. Orders from LNG and nuclear clients, particularly around plant extensions and SMR development, are expected to sustain mid-single-digit growth into 2026 and beyond. Hydrogen infrastructure, while lumpy, offers additional upside. Though 2024 saw a shipment-heavy performance, the order pipeline remains robust, with energy security needs supporting capex across IMI's core regions. While growth may not maintain the double-digit pace of 2023, the structural demand drivers suggest a reliable, compounding revenue stream.

Can IMI offset the margin drag from Transport and Industrial Automation?

The Transport division has underperformed for years, but the recently launched 5-year transformation plan aims to lift its return on capital to group levels. This includes targeted exits from low-margin business lines, leaner operations, and engineering-led margin improvement on new platforms. The Industrial Automation segment, though cyclical, has stabilised and benefits from high aftermarket exposure and growth from electrification-related clients. IMI’s 20% group margin target includes these divisions and assumes improvement. Analysts believe the high-margin Process Automation and Climate Control segments will provide enough cushion to protect profitability during the transition, and that Industrial Automation’s operational gearing offers strong upside when end markets recover.

How scalable is OneIMI into acquired businesses?

Scalability of OneIMI is a key differentiator in IMI’s M&A strategy. Management sees the operating model not just as a cost tool but as a cultural integration platform. The OneIMI pillars – commercial excellence, data-driven operations, continuous improvement, and innovation – have been successfully applied to several bolt-ons, delivering returns above WACC within three years. In practice, the post-acquisition playbook is well structured: IMI embeds central teams early, applies shared KPIs, and deploys digital tools to track performance. This accelerates alignment, shortens time-to-value, and allows IMI to pursue smaller acquisitions with confidence. Investors view this capability as giving IMI a competitive advantage in fragmented sectors like fluid handling, where scale and sophistication can unlock substantial synergies.

Where is capital being deployed in 2026 and beyond?

Future capital deployment remains focused on three main areas: strengthening core capabilities, accelerating digital innovation, and enabling strategic M&A. On the organic side, capex is allocated toward manufacturing automation, cybersecurity, and facility upgrades that improve flexibility and responsiveness. IMI has also invested in new product platforms through its Growth Hub, particularly in clean energy and life science control systems. On the inorganic side, the pipeline of bolt-ons remains active, with management reiterating its 3-year payback hurdle and commitment to disciplined pricing. With net leverage forecast to fall below 1.1x by end-2025, share buybacks remain an option, although M&A is expected to be the primary outlet for surplus capital. Investors see the capital allocation framework as pragmatic, with a clear focus on compounding shareholder returns over time.

What’s the status of Life Science and Fluid Control recovery?

This division, while only 10% of group sales, is a strategic growth vector given its exposure to medical devices, analytical instruments, and lab infrastructure. Growth was muted post-COVID, but Q3 showed a 13% organic bounce, partly driven by shipment catch-up. Management indicates underlying demand has stabilised, particularly in diagnostics and point-of-care equipment. As funding returns to biotech and pharma labs, and as postponed capex resumes, IMI expects a gradual return to low-single-digit organic growth, and has begun expanding its Swiss Life Science manufacturing facility to meet sustained demand. Structural growth remains intact, supported by demographic shifts, chronic disease trends, and a growing focus on automation in lab environments. Fluid Control’s ability to support high-precision, miniature flow systems makes it well placed to benefit as innovation picks up in medtech and life sciences. Investors are watching closely for signs of sustained improvement in order books and recurring business.
