Overview

A class action lawsuit has been filed against Ostin Technology Group Co., Ltd., (“Ostin Tech,” or the “Company”) (NASDAQ : OST) and certain of the Company’s senior executive officers (collectively, “Defendants”) alleging violations of federal securities laws. The Ostin Tech lawsuit is brought on behalf of all persons and entities who purchased or otherwise acquired Ostin Tech securities between May 11, 2025, and June 26, 2025, inclusive (the “Class Period”). Investors have until April 17, 2026, to seek appointment as lead plaintiff of the Ostin Tech class action lawsuit.

Ostin Tech is a manufacturer of thin-film transistor liquid crystal display (“TFT-LCD”) modules and polarizers used in consumer electronics, commercial LCD displays, and automotive displays.

The Ostin Tech lawsuit alleges that beginning in April 2025, Defendant, Lai Kui Sen, Ostin Tech’s Chief Executive Officer (“CEO”), and co-conspirators, engineered a fraudulent sequence of securities offerings specifically designed to place the majority of Ostin Tech shares in the hands of at least fifteen co-conspirators (the “Select Investors”) for pennies per share or, in many cases, for no consideration whatsoever. These securities offerings were synchronized with a fraudulent campaign to artificially inflate the price and trading volume of the Ostin Tech stock through social media and messaging service applications, including paid promotions that impersonated actual investment advisors and financial professionals. In a period of roughly two months, the fraudulent promotional campaign artificially inflated the value of Ostin Tech from an approximately $22 million company (based on a stock price of $0.78 per share on April 14, 2025) into a greater than $1 billion company by market capitalization (based on a peak stock price of $9.40 per share on June 26, 2025).

The lawsuit alleges that at the height of the fraud, the Defendants and their co-conspirators engaged in a massive selloff of their fraudulently obtained securities, obtaining more than $110 million in proceeds from the sale of Ostin Tech stock which victimized unwitting investors. On June 26, 2025, Ostin Tech investors suffered devastating losses when the selloff destroyed over $950 million of Ostin Tech’s market capitalization in a single day. The stock plummeted from an intraday high of $9.40 to a closing price of $0.55, a decline over 94%.
