Cosmo Robotics shares fell 29.98% to 7,520 won on September 30 after the Seoul Metropolitan Police Agency raided the company's Seoul headquarters over alleged revenue inflation before its KOSDAQ IPO. Investigators suspect the company overstated 2025 revenue by about 3.5 billion won, or $2.58 million, through robot sales that did not reflect actual transactions. The disputed amount represents roughly 40% of the 8.86 billion won in consolidated revenue reported for 2025. The company denies wrongdoing, says the sales were legitimate, and is cooperating with the investigation while reviewing its accounting controls.
