Elliott, which manages more than $80 billion in assets, has been engaging with the Paris-based company for months, urging management to boost margins and improve operational efficiency, sources familiar with the matter told Reuters. The exact size of the hedge fund's stake could not immediately be determined. Both Elliott and Air Liquide declined to comment.devdiscourse+1

Shares in Air Liquide jumped nearly 4% in early Tuesday trading, putting the stock on track for its largest one-day gain in six months.investing+1

A Widening Gap With Linde

At the heart of Elliott's campaign is Air Liquide's margin shortfall relative to Linde ↗ 2.58%, the sector leader. Linde's operating margin stood at roughly 30% as of mid-2026, compared with about 21% for Air Liquide, according to LSEG data cited by Reuters. Analysts expect the gap to persist for several years without sharper execution.reuters+1

J.P. Morgan JPMorgan Chase & Co. ↗ 4.18% analysts noted that one of the main drivers of the disparity was Air Liquide's lower sales per employee, suggesting scope for further efficiency measures. Linde has also been far more aggressive in returning capital to shareholders, repurchasing $4.6 billion in shares in 2025 alone, while Air Liquide executed just €167 million in buybacks earlier this year.devdiscourse+1

Air Liquide, which supplies gases including oxygen, nitrogen, and hydrogen to factories, hospitals, and semiconductor plants, ranks among the top three global players alongside Linde and Air Products and Chemicals ↗ 1.89%.devdiscourse

October Investor Day in Focus

The company has scheduled an investor day on October 5, where shareholders are hoping management will lay out a roadmap for margin improvements and detail additional share buybacks. Analysts at Bernstein said Air Liquide was not an obvious candidate for a traditional activist campaign but noted that Elliott's involvement could increase pressure on management, with a buyback announcement serving as a near-term catalyst.marketscreener+2

With a market capitalization of roughly €108 billion, Air Liquide would be Elliott's largest target on Euronext to date.devdiscourse+1
