Financial authorities have imposed sanctions on executives and associates of NH Investment & Securities for alleged insider trading related to tender offers. The Securities and Futures Commission (SFC), under the Financial Services Commission, has filed criminal charges and imposed the maximum administrative fines as part of a strong response to actions that undermine the capital market order.
On May 21, the SFC announced that during its 10th regular meeting on May 20, it reported eight individuals, including executives and their spouses and acquaintances, to prosecutors for violating the Capital Markets Act by using undisclosed important information. Additionally, it decided to impose fines on eight others who received and traded on this information for violating market disruption regulations.
This action follows a joint investigation by the Financial Services Commission, the Financial Supervisory Service, and the Korea Exchange. Authorities believe that undisclosed information obtained during the tender offer process was leaked and used for stock trading.
According to the SFC, the suspects allegedly used undisclosed information acquired while conducting tender offer-related work from May 2023 to September 2025 to make concentrated purchases of stocks from 15 listed companies. They are accused of selling their shares for illicit profits after the stock prices rose following the announcement of the tender offers.
Authorities view the use of proxy accounts by executives and their spouses to conceal trades as a serious matter. Investigations revealed that spouses mimicked their husbands' trading methods by using accounts in the names of other acquaintances. The joint response team confirmed the actual ownership of multiple accounts and collusion through fund tracking and searches.
In addition to the criminal charges, authorities stated that the eight individuals who traded based on insider information would face the highest possible fines under the law to raise market awareness.
Furthermore, depending on the results of the prosecutors' investigation, authorities plan to impose additional fines of up to twice the amount of illicit profits on those accused of using insider information.
Previously, NH Investment & Securities established a task force to strengthen internal controls immediately after becoming aware of the situation in October of last year. The company has implemented comprehensive measures, including requiring all executives to submit compliance pledges, banning new stock purchases, introducing a registration management system for employees handling undisclosed important information, expanding monitoring of accounts held in family members' names, and formalizing a 'one-strike-out' principle.
