INEOS

INEOS Group Limited is one of the world’s largest privately owned chemical companies, headquartered in London and founded in 1998. The group’s operations span a wide spectrum of industries, including petrochemicals, specialty chemicals, oil and gas, packaging, automotive, pharmaceuticals, textiles, and even elite sports sponsorship. With approximately 26,000 employees across 36 business units and 194 production sites in 29 countries, INEOS plays a influential role in global manufacturing and industrial supply chains.

The company is structured into numerous independent units, each responsible for a specific segment such as olefins and polymers, phenol and derivatives, and oil & gas. Reputation for aggressive expansion through acquisition has positioned INEOS as a leader in commodity chemicals, with outputs ranging from acetyls and aromatics to polypropylene and polystyrene. A growing focus on circular economy initiatives is reflected in investments in advanced recycled plastics.

Sir Jim Ratcliffe, a chemical engineer turned entrepreneur, remains the group’s chairman and CEO. Under his leadership, the company has diversified its portfolio, including launching Ineos Automotive—manufacturer of the off-road Grenadier and Quartermaster vehicles—and forming a high-performance cycling team, Ineos Grenadiers. The group also supports academic research via a £100 million investment in the Ineos Oxford Institute for Antimicrobial Research.

Despite strong cash flows, INEOS faces scrutiny due to financial leverage, with debt levels nearing €12 billion. Credit agencies have issued negative outlooks amid industry volatility in energy and chemical markets. Nevertheless, the group continues to explore growth paths in private markets, sustainable feedstocks, and the industrialisation of hydrogen and CO₂ management technologies. Recent developments include spinning off Ineos Styrolution and restarting Grenadier manufacturing in France.

INEOS maintains its largest manufacturing campus in Grangemouth, Scotland, where it recently inaugurated a new headquarters following a £450 million investment in site regeneration. The modern facility consolidates office functions and supports the ongoing industrial renaissance in the region.
