2CRSi shares collapsed 43% Thursday after Grizzly Research disclosed a short position. The company requested a halt to prepare its rebuttal.
The Collapse
Shares in 2CRSi, the French server and data center hardware manufacturer, plunged 43% on Thursday after Grizzly Research disclosed it had taken a short position in the stock. Trading was halted twice during the session due to extreme volatility, and the company has now requested that Euronext suspend trading while it prepares a formal response.
The stock dropped to €25.40 before the second halt. Shares had not reopened by Thursday's close, and the suspension will remain in place until 2CRSi issues what it calls a documented response to the short seller's allegations. Portzamparc analysts expect that response by Monday.
This is the sharpest single-day move in 2CRSi's history as a public company. The Strasbourg-based firm, which designs and manufactures energy efficient servers and AI infrastructure, has roughly 112 employees and markets its products in more than 50 countries.
The Grizzly Report
Grizzly Research is a U.S. activist short seller known for detailed forensic reports on companies it believes are overvalued or have accounting irregularities. The firm did not disclose the specific allegations in its initial announcement, but Portzamparc analysts noted that the report focuses on 2CRSi's relationship with a customer called NYGC.
Portzamparc described the Grizzly report as well constructed and said it exploits the company's lack of communication about its NYGC relationship, which the brokerage believes goes beyond a simple customer and supplier arrangement. The opacity around that relationship appears to be the central vulnerability Grizzly is targeting.
Activist short sellers have become a powerful force in European markets over the past several years. Their reports often trigger immediate, severe price moves as algorithms and momentum traders react before fundamentals can be assessed.
Company Response Pending
2CRSi requested the Euronext halt itself, a move that buys time but also signals the company views the allegations as serious enough to require a structured rebuttal. The firm has not issued any preliminary statement disputing Grizzly's claims.
This silence is typical in such situations. Companies targeted by short sellers often take 24 to 72 hours to assemble legal, accounting, and communications teams before responding. A rushed denial can backfire if it fails to address the specific claims or if it contains errors.
The suspension also freezes the pain for existing shareholders. Anyone holding shares at Thursday's close is locked in until trading resumes, which could be Monday or later depending on when 2CRSi finalizes its response.
The Short Seller Playbook
Grizzly's approach follows a familiar pattern. Activist short sellers build a position, publish a damaging report, and profit as the stock falls. The practice is legal and, in many cases, serves a market function by exposing fraud or accounting irregularities that analysts and auditors miss.
The tactic is also controversial. Critics argue that short sellers can profit from panic selling triggered by sensational claims that turn out to be exaggerated or false. The targeted company faces an asymmetric fight: the short seller has already positioned, while the company must respond in real time under scrutiny.
Grizzly has previously targeted companies in the technology and healthcare sectors. Its reports have had mixed track records, with some leading to lasting valuation resets and others eventually proven overblown.
Market Context
The attack on 2CRSi comes at a sensitive moment for European tech hardware stocks. Server demand has been volatile as hyperscalers alternate between aggressive AI infrastructure buildouts and periodic pauses to digest capacity. Companies with concentrated customer bases are particularly vulnerable to scrutiny.
2CRSi had positioned itself as a beneficiary of the AI infrastructure wave, and its shares had rallied through early 2026 on that narrative. The Grizzly report challenges whether the underlying revenue is as solid as the market believed.
French regulators at the Autorité des Marchés Financiers have not commented on the situation. The AMF has the authority to ban short selling in specific stocks under extreme conditions but has not indicated any such action on 2CRSi.
What to Watch
The next catalyst is 2CRSi's official response, expected by Monday according to Portzamparc. The quality of that rebuttal will determine whether shares stabilize or continue lower when trading resumes.
Investors should watch for specifics. If 2CRSi can produce documentation showing its NYGC relationship is standard and its revenue recognition is appropriate, the stock could recover a portion of Thursday's losses. If the response is vague or fails to address Grizzly's key claims, the selloff could resume.
The suspension also creates technical risk. When trading resumes, pent-up selling pressure from shareholders who wanted to exit Thursday but could not may hit the order book immediately. The first print after reopening will reveal how much confidence remains.
