Carbios Faces Shareholder Storm as China Plant Delay and New CEO Collide
11.06.2026 - 23:33:31 | boerse-global.de
The clock is ticking for Carbios’s management team. With the annual shareholder meeting scheduled for June 18 in Paris, the French biorecycling pioneer is confronting a revolt from its own investor base. The activist group ADISECT has submitted a list of demands, including the removal of board members who backed the company’s troubled partnership with Chinese conglomerate Wankai.
Investor fury stems from a series of setbacks surrounding the joint venture in Haining, China. The facility, which was intended to mark Carbios’s international debut in PET biorecycling, will not begin operations until the first half of 2028 – a delay the company attributes to additional technical adjustments needed to scale its enzyme technology for local conditions. That postponement has frozen a previously anticipated capital injection: Wankai has put a €5 million equity infusion on ice, with Carbios now expecting the funds no earlier than late December 2026.
The timing could not be more fraught. Benoît Grenot, promoted from deputy to chief executive officer on June 1, faces his first major test weeks into the job. He must soothe angry shareholders while steering a company whose stock has been hammered. On Thursday, shares touched a new 52-week low of €5.05, and the stock now trades near €5.18, having shed more than 55% of its value since the start of the year. The decline has accelerated sharply: in the last seven days alone, the share price tumbled roughly 20%.
Should investors sell immediately? Or is it worth buying Carbios?
Technical indicators suggest the selling may have gone too far. The relative strength index (RSI) has fallen to around 23, a deeply oversold level that often precedes a short-term bounce. Yet buyers remain on the sidelines, wary of the broader uncertainty.
Carbios does have a financial buffer. The company ended its 2025 fiscal year with €59 million in cash, enough, it says, to fund operations for the next twelve months without a liquidity squeeze. That cushion also supports its European flagship project in Longlaville, France, where construction on the first wholly owned PET biorecycling plant began in spring 2024. That facility, too, is now scheduled to start up in the first half of 2028, running on a parallel timeline to the Chinese venture.
The June 18 meeting will bring the tension to a head. Shareholders are set to vote on capital measures and board composition. If ADISECT musters a majority for its personnel demands, Carbios will be forced to redraw its China strategy completely – and Grenot’s honeymoon will be over before it even began.
