1. Tecnoglass Inc. has filed a defamation lawsuit against a short seller. 2. Allegations link Tecnoglass to the Sinaloa cartel, which are claimed false. 3. The lawsuit seeks damages and a retraction of defamatory statements. 4. Culper Research is accused of benefiting from false allegations impacting stock prices. 5. Previous similar defamation suits against Culper Research have occurred.
A successful defamation case could restore Tecnoglass's reputational integrity, enhancing investor confidence. Historical instances show recovery post-defamation suits can bolster stock values.
The defamation claims directly target TGLS’s reputation and stock price, making it vital for investors. The outcome may significantly influence market sentiment towards TGLS.
The immediate effects of the lawsuit could influence Tecnoglass's stock price in the near term. However, long-term impacts depend on the lawsuit's outcome and market sentiment.
NEW YORK, Sept. 10, 2025 /PRNewswire/ -- Alex Spiro announced that yesterday he has filed a federal defamation lawsuit in the Southern District of New York on behalf of Tecnoglass Inc. (NYSE:TGLS) and its co-founders and executives, José and Christian Daes. The complaint names short seller Christian Lamarco and his firm Shadyside Partners, LLC (d/b/a Culper Research), alleging they deliberately published false claims linking Tecnoglass and its executives to the Sinaloa cartel.
The filing asserts that Culper Research profited from short positions by spreading fabricated allegations sourced from purported "intelligence" documents that the Mexican government has publicly confirmed are inauthentic.
The complaint also notes this is not the first time Lamarco and Culper Research have faced defamation suits of this nature. The report caused immediate damage to Tecnoglass's share price and reputation. The plaintiffs seek damages, attorneys' fees, and an injunction requiring the removal and retraction of the defamatory statements.
The case is Tecnoglass Inc. v Lamarco, 25-cv-7450, U.S. District Court, Southern District of New York.
