Prosecutors Simultaneously Raid Samsung and Rainbow Robotics

On the 18th, the Financial and Securities Crime Joint Investigation Division of the Seoul Southern District Prosecutors' Office conducted raids on Samsung Electronics' Suwon facility and Rainbow Robotics' Daejeon headquarters. This action was taken to investigate allegations of insider trading that occurred during Samsung Electronics' acquisition of Rainbow Robotics.

Prosecutors have identified 16 individuals as suspects, including Rainbow Robotics' CEO, former CFO Bang, and a Samsung Electronics executive, and are conducting an investigation. These individuals are suspected of using undisclosed information to gain illicit profits of 3 to 4 billion won during Samsung Electronics' acquisition of Rainbow Robotics shares between 2022 and 2024.

Financial Authorities Refer Case to Prosecutors After Year-Long Investigation

The Financial Supervisory Service and the Financial Services Commission's Securities and Futures Commission referred the case to prosecutors in February after conducting an investigation for over a year. The Securities and Futures Commission formally charged two individuals, including Rainbow Robotics' former CFO and a Samsung Electronics executive, with violations of the Capital Markets Act, and requested investigations into the remaining 14 individuals.

Financial authorities have determined that these individuals purchased large quantities of stock after obtaining non-public information in advance during Samsung Electronics' process of becoming Rainbow Robotics' largest shareholder. Rainbow Robotics started at 10,000 won per share when it was listed on KOSDAQ in 2022 and showed a sharp increase as news of Samsung Electronics' acquisition became known.

Allegations Linked to Samsung's Robotics Business Expansion

This incident arose during Samsung Electronics' development of the robotics business as a future growth engine. Samsung Electronics gradually acquired shares in Rainbow Robotics from 2022 and became its largest shareholder in 2024. Rainbow Robotics is a leading Korean robotics company recognized for its technological capabilities in collaborative robots and service robots.

A prosecution official stated, "We will thoroughly investigate whether there were any unfair trading practices using undisclosed information during the acquisition process," adding, "We will analyze the seized materials to identify additional suspicious activities."

Concerns Over Damage to Capital Market Trust

This case is evaluated as revealing structural vulnerabilities that allow insider trading to occur during large corporations' M&A processes. In particular, as employees with access to relevant information during the acquisition process of listed companies are suspected of using information asymmetry to gain illicit profits, concerns about the fairness of capital markets are growing.

Financial authorities have been strengthening monitoring of insider trading during large corporate M&A processes recently, and plan to apply related regulations more strictly in light of this incident.
