Air Liquide rises 4.2% as Elliott builds stake, pushes margins
Air Liquide shares rose as much as 4.2% on Tuesday after activist Elliott Investment Management built a stake in the French industrial gases company.
Elliott has engaged with Air Liquide for months, urging management to improve margins to better compete with rivals in the industrial gases sector, people familiar with the matter said. The exact size of the stake was not disclosed. Elliott declined to comment, and Air Liquide did not respond to a request for comment.
The margin gap between Air Liquide and Linde has widened in recent years, LSEG data shows. As of mid-year 2026, Linde's operating margins were 30 percent, compared with Air Liquide's 21 percent. Analysts said that gap is expected to remain steady for several years, giving Air Liquide management room to make improvements.
Linde, with a market value of $225 billion, repurchased $4.6 billion in shares in 2025. Air Liquide authorized buybacks last year but executed them in late February to early March of 2026, coming to €167 million ($193 million), according to company filings.
Air Liquide, valued at roughly €108 billion ($125.5 billion), has an investor day scheduled for early October, where investors hope management will reveal plans to improve margins and detail additional share buybacks. The company's electronics division, which supplies gases for AI chips, has been called a growth engine hidden within the industrial gases business because of the ongoing AI infrastructure buildout.
Elliott, which manages $80.3 billion in assets, has stepped up its European push in recent years, investing in oil major BP, the London Stock Exchange operator, and German utility RWE. It recently pushed for changes at the London Stock Exchange Group and chip design software giant Synopsys, and pressured spirits group Pernod Ricard in 2018 after acquiring 2.5 percent of its equity.
Linde has returned €45 billion to shareholders over the past decade, versus €14 billion for Air Liquide, according to the Financial Times. Air Liquide's two main competitors are Linde and Air Products and Chemicals.
The activist's arrival forces Air Liquide management to make the group more attractive to shareholders. Investors will watch the October 5 investor day for concrete margin targets and buyback commitments.
