IMI plc[3] (LSEIMI), formerly Imperial Metal Industries Limited (1962–1968)[4] and IMI Limited (1978–1981),[5] is a British-based engineering company headquartered in Birmingham, England. It is listed on the London Stock Exchange and is a constituent of the FTSE 100 Index.

Key Information

History

[edit]

The company was founded by Scottish entrepreneur George Kynoch who opened a percussion cap factory in Witton, West Midlands in 1862, trading as Kynoch.[6] The business soon diversified, manufacturing goods ranging from soap and bicycle components to non-ferrous metals, but by the early 20th century it had developed particular expertise in metallurgy.[6] After World War I it merged with Nobel Industries.[6] In 1926 the company acquired Eley Brothers, an ammunition business.[7] The company, by then known as Nobel Explosives, was one of the four businesses that merged in 1927 to create Imperial Chemical Industries.[6] The Witton site became the head office of ICI Metals.[6] During the Second World War the Witton site was used for the development and production of uranium for the Tube Alloys project.[8]

In the 1950s the company's researchers perfected the process for producing titanium on a commercial basis.[6] In 1958 ICI Metals bought 50% of Yorkshire Imperial Metals: it acquired the other 50% four years later.[9]

The name Imperial Metal Industries Limited (IMI for short) was adopted on the 100th anniversary of the firm in 1962.[6] The company was listed on the London Stock Exchange in 1966.[6] Initially ICI retained a majority holding, but in 1978 IMI became fully independent.[6] In the 1990s the Company disposed of its more basic businesses such as metal smelting and metal founding.[6]

In 2003, IMI moved from the Witton site to new headquarters close to Birmingham Airport.[10]

The company announced in October 2013 that a decade-long programme of transformation had been completed with the disposal of two non-core subsidiaries to Berkshire Hathaway for £690m.[11] The disposal of the Cornelius Group, a beverage-dispensing machine business, together with the disposal of a marketing intelligence business, would enable the company to focus on its control valve making business.[12]

In November 2022, it was announced IMI had acquired the Blackburn-based smart thermostatic control manufacturer, Heatmiser, for £110 million.[13]

History

Founding and early development

IMI plc traces its origins to 1862, when Scottish entrepreneur George Kynoch established a percussion cap and cartridge manufacturing business in Witton, Birmingham, , initially trading as Ltd. The company quickly grew into a key player in the ammunition industry, leveraging the demand for metallic cartridges during the late . By the , Kynoch had expanded its operations at the Lion Works site, incorporating advanced machinery for precision production of explosives and related components, which honed its expertise in and processes. In the early , diversified beyond pure , venturing into metals fabrication and ancillary products such as components and tools, reflecting the broader industrial boom in Birmingham. This period solidified the company's focus on high-precision manufacturing, particularly in handling metals and explosives, which became foundational to its later engineering capabilities. By the outbreak of , was one of Britain's largest producers, supplying , fuses, and cartridges from multiple facilities across the . Following , in 1918, merged with other major manufacturers, including Eley Brothers, to form Explosives Trades Ltd., which was renamed Nobel Industries in 1920; this consolidation positioned the entity as the core of ' division upon the 1926 merger forming ICI. The integration of Eley Brothers' expertise in the late and further consolidation by 1926 expanded production into sporting and military cartridges, enhancing 's market dominance in precision munitions. These early developments in explosives and metals laid the groundwork for IMI's transition into broader under ICI oversight.

Association with ICI and independence

In 1926, Imperial Chemical Industries (ICI) was established through the merger of four major British chemical firms, including Nobel Industries, which encompassed explosives, , and nonferrous metals operations previously associated with companies like . These activities were integrated into ICI as the Nobel Division, initially concentrating on defense-related products such as explosives and , alongside industrial chemicals involving , , and other metals essential for manufacturing and applications. This structure allowed the division to leverage wartime expertise in propellants and munitions while expanding into peacetime industrial uses, such as metal alloys for construction and machinery. By the early , the metals operations had evolved significantly, prompting a reorganization. In 1962, to commemorate the centenary of George Kynoch's original factory, ICI renamed its Metals Division as Imperial Metal Industries (IMI), consolidating subsidiaries focused on nonferrous metals and related . Under this banner, IMI pursued diversification beyond its ammunition roots, acquiring firms specializing in components like carburetors, zip fasteners, and heat exchangers, thereby broadening into automotive, , and consumer goods sectors. This strategic shift emphasized advanced and fluid control technologies, reducing reliance on defense contracts and aligning with growing demand for specialized industrial materials. In 1966, IMI was listed on the London Stock Exchange, marking a partial step toward while ICI maintained a majority stake to oversee its subsidiary's expansion. This public flotation provided capital for further acquisitions and investments in innovation, such as nuclear components and precision valves, solidifying IMI's position as a key player in metals and . By 1978, ICI divested its remaining shares, granting IMI full and allowing it to operate as a standalone for the first time since its absorption into the conglomerate.

Restructuring and modern growth

Following its demerger from in 1978, IMI plc embarked on a series of strategic transformations to streamline operations and concentrate on specialized . In the , the company divested its basic metal businesses, including rolled metals, , and founding operations, to refocus on higher-value activities such as fluid control systems. This disposal, initiated around 1990, marked a pivotal shift away from commodity metal processing toward advanced technological applications. To enhance operational efficiency, IMI relocated its headquarters in 2003 from the historic Witton site in Birmingham to the Birmingham Business Park near the airport, facilitating better and global connectivity. A further major restructuring occurred in 2013 when IMI sold its non-core Beverage Dispense and Merchandising divisions to Berkshire Hathaway's for £690 million, allowing the company to sharpen its emphasis on core engineering segments. In recent years, IMI has pursued growth through targeted acquisitions to strengthen its capabilities in . In November 2022, the company acquired UK Ltd for an enterprise value of £110 million, expanding its presence in connected residential thermostatic controls within the climate control sector. More recently, in October 2024, IMI acquired TWTG Group B.V. for an enterprise value of €32 million, integrating advanced (IIoT) solutions for asset monitoring in process automation. Underpinning these changes is IMI's 2019 growth strategy, which solidified its positioning as a global leader in and motion control technologies. This approach prioritizes , including energy-efficient solutions and reduced emissions, alongside partnerships for innovation in and .
