Summary
Brunello Cucinelli faced severe market turbulence on September 25, 2025, when short-seller Morpheus Research published a report alleging the Italian luxury goods manufacturer misled shareholders regarding its Russian business activities. The allegations centered on claims that the company continues to operate stores in Moscow despite EU sanctions on luxury goods sales in Russia. The report triggered an immediate 5% decline in share price, prompting the Italian Stock Exchange (Borsa Italiana) to suspend trading. When trading resumed, shares closed down 17.3% at 85.08 euros, reflecting sustained investor concern over the allegations.

CEO Luca Lisandroni issued a formal response rejecting the short-seller's claims during a presentation of the company's spring collection. Lisandroni acknowledged the market turbulence while defending the company's operational integrity, stating: "We are deeply disappointed by the strong turbulence created on our shares by a short-selling fund. In this case, probably not finding any critical element, the fund produced and spread a defaming report on our activities in Russia." He characterized Morpheus Research as a fund that "bets on the difficulties of a company" and suggested the report was manufactured due to an inability to identify genuine operational vulnerabilities.

In its official response, Brunello Cucinelli stated that its Russian subsidiary maintains full compliance with all applicable regulations and confirmed it is actively considering legal action against Morpheus Research. The company framed the allegations as baseless attacks designed to manipulate share price downward for the benefit of short-sellers. Despite management's denial and defense of regulatory compliance, the market's sharp repricing indicates significant investor skepticism regarding the company's Russian operations and questions about disclosure transparency regarding sanctions exposure.
