Coupang, Inc. (NYSE: CPNG), a prominent player in the global technology and commerce sector, is currently facing a class action lawsuit. The notice, issued by Robbins LLP on December 24, 2025, reminds shareholders that the deadline to apply as a lead plaintiff in the case is fast approaching. The class action pertains to investors who purchased or acquired Coupang securities between April 6, 2025, and December 16, 2025, a critical period during which serious allegations about the company’s cybersecurity practices have come to light.

2. Allegations of Cybersecurity Failures

The lawsuit centers around significant claims that Coupang allegedly failed to adequately disclose a material cybersecurity incident. According to the complaint, the company is accused of:

Inadequate Cybersecurity Protocols: The lawsuit alleges that Coupang did not maintain sufficient cybersecurity measures, allowing a former employee to access sensitive customer information undetected for nearly six months.

Heightened Regulatory Risk: This breach purportedly placed Coupang at a greater risk of regulatory and legal scrutiny, potentially exposing the company to severe penalties and damage to its reputation.

Failure to Report the Incident: When the company became aware of the data breach, it allegedly did not report it in compliance with the U.S. Securities and Exchange Commission's current report filing requirements. This failure to disclose critical information may have misled investors, leading to a decline in Coupang's stock price once the details of the breach were made public.

As a result of these allegations, investors who purchased Coupang shares during the specified period experienced financial harm, prompting the initiation of this class action.

3. Implications for Shareholders

Shareholders interested in participating in the class action are encouraged to consider their options.
