Rosen, Gross Renew Calls for Coupang Investors to Seek Lead Role in Data-Breach Securities Case

Overview

• New notices on December 29 urge purchasers of Coupang securities between August 6 and December 16, 2025 to move by February 17, 2026 for lead-plaintiff consideration.
• Complaints assert Coupang’s cybersecurity controls were inadequate, allowing a former employee to access sensitive customer information for nearly six months without detection.
• Filings claim the company did not submit a timely current report to the SEC about the incident, rendering prior statements misleading and causing investor losses when details became public.
• At least one case, Barry v. Coupang, Inc., No. 5:25-cv-10795, is pending in the Northern District of California as additional firms solicit class members and conduct investigations.
• No class has been certified, and investors may choose counsel or remain absent class members, with contingency arrangements offered and no out-of-pocket fees required to register.
