Elliott Management has built a position in €90 billion French industrial gas producer Air Liquide, according to press reports confirmed by regulatory filings, targeting margin expansion and operational restructuring at a company that has traded at a 15% discount to its ten-year valuation multiple since mid-2023. The stake size has not been disclosed, but Elliott typically deploys $500 million to $2 billion in European campaigns of this scale.
The Air Liquide filing arrived alongside 13D disclosures on at least four other public companies this week: Immatics (NASDAQ: IMTX, $680 million market cap), Exelixis (NASDAQ: EXEL, $8.1 billion), Valaris (NYSE: VAL, $4.3 billion), and an unnamed fifth target. Immatics, a clinical-stage T-cell receptor therapy developer, saw a filing from an undisclosed activist holding roughly 8% of shares outstanding. Exelixis, the oncology-focused biotech behind cabozantinib, received a Schedule 13D from a fund advocating capital allocation review after the company's cash position exceeded $1.9 billion at year-end. Valaris, the offshore drilling contractor, faces pressure from a shareholder group pushing for fleet rationalization and a return-of-capital program after free cash flow reached $430 million in trailing twelve months.
The cluster matters because activist filings typically compress into narrow windows ahead of proxy deadlines, and this batch arrived 73 days before the April 30 annual meeting cutoff for most U.S.-listed firms. When five or more campaigns surface in a single week, historically 40% of those targets see at least one board seat flip or operational concession within six months, according to FactSet activism data covering 2018-2023. Elliott's entry into Air Liquide is particularly notable: the firm has never previously filed a public position in a French CAC 40 component, and French corporate governance rules allow activists to request extraordinary shareholder meetings with just 5% ownership, a threshold Elliott likely already exceeds. Air Liquide's operating margin has declined 180 basis points since 2021 despite stable volumes, a gap Elliott will almost certainly frame as execution failure rather than market headwinds.
For allocators, the relevant tell is not the individual campaigns but the signaling function. Activists deploy capital when they expect six-to-eighteen-month catalysts—earnings misses that validate intervention, M&A interest from strategics, or regulatory clarity that allows restructuring. Elliott's timing on Air Liquide coincides with the European Central Bank's third consecutive rate cut, which tends to compress industrial multiples and make operational activism cheaper to finance. The Exelixis and Immatics filings both landed within 48 hours of FDA calendar updates that could accelerate pivotal trial readouts, a classic biotech activist setup. Valaris, meanwhile, trades at 0.9x tangible book despite a $12 billion offshore drilling backlog industry-wide, the kind of dislocation that draws in both activists and M&A interest from larger contract drillers.
Watch for follow-on 13D amendments in the next 21 days—activists often file initial stakes at just above 5%, then quietly add another 2-3% before the amendment deadline. If Elliott crosses 7.5% in Air Liquide, French disclosure rules will force a public statement of intent, which typically includes specific margin or ROIC targets. Exelixis is up for re-election of three board seats at its June annual meeting; any activist filing now has time to nominate opposing slates. Immatics has a €380 million net cash position and no approved products, making it a candidate for either a sale process or a pivot to out-licensing, both of which activists can force through special committee pressure.
The cleanest read is leverage resetting. Activists file when they believe management has over-indexed on optionality and under-indexed on return of capital. Elliott does not build stakes in €90 billion companies to earn 6% annually.
The takeaway
Five activist filings in one week, with Elliott entering Air Liquide, signals Q1 positioning ahead of proxy season and rate-cut volatility.

Your next customer won't visit your website. Their AI will.
AI assistants have quietly taken over the first step of buying — they answer from catalogs they can read and shortlist whoever can actually ship. Two questions now decide whether you exist to that buyer: can a machine read your catalog, and can you fulfill the order. Most brands fail one or both and never find out why the orders went elsewhere. The winners of this shift aren't the loudest. They're the most readable. Build for the machine that's about to do the shopping.
