U.S. or Korea? Coupang's data breach lawsuit faces key jurisdiction question.

U.S. or Korea? Coupang's data breach lawsuit faces key jurisdiction question. In a pretrial conference, a New York judge questioned whether a class-action suit over Coupang's data breach should proceed in the United States while plaintiffs cited company's NYSE, SEC connections. Published September 2, 2026 - 3:23 p.m. Modified September 2, 2026 - 7:01 p.m. A U.S. class-action lawsuit over Coupang's massive data breach began with a fundamental question: Should the case be heard in the United States or in Korea? While Coupang claims to be a U.S.-based company in its lobbying and outreach to U.S. officials, at the same time it is arguing that a New York federal court lacks jurisdiction over a breach that took place on its Korean platform. During the first pretrial conference against Coupang that took place on Tuesday in New York, presiding judge Ann M. Donnelly repeatedly questioned why the lawsuit should be heard at the United States District Court for the Eastern District of New York rather than in Korea. A pretrial conference allows the judge to hear arguments from both sides, identify key issues and set a schedule for further proceedings before the case moves onto an actual trial. Daeryun Law Firm and its U.S. partner, SJKP Law Firm, earlier filed a class-action lawsuit on behalf of Coupang customers against Coupang Inc. - the U.S. parent company of the e-commerce platform - as well as company founder Bom Kim and others. The plaintiffs alleged that the platform failed to protect customers' personal data and breached its duty of care. They also sought $5 million in damages. Two Coupang customers living in the jurisdiction of the Eastern District of New York are serving as lead plaintiffs. About 7,800 people have so far expressed interest in joining the lawsuit. Coupang Inc.'s attorneys from U.S. law firm Kirkland & Ellis asked the court to dismiss the lawsuit. They argued that a breach that occurred in Korea did not justify bringing a U.S. class action against Coupang Inc. They further argued that Coupang Inc. - a holding company incorporated in Delaware - is legally distinct from its Korean subsidiary, Coupang Corp. Coupang's attorneys characterized Coupang Corp. as an e-commerce platform that operates in Korea for Korean consumers, and said that pursuing the case in a U.S. court would only waste time and resources. The irony is that argument stands in direct contrast to Coupang's recent efforts in Washington, where it has emphasized its contributions to U.S. job creation and exports. Some members of the U.S. Congress, including the House Judiciary Committee, have also portrayed Coupang as a U.S. company facing discriminatory treatment from the Korean government. Coupang Inc. also pointed to ongoing investigations by several Korean authorities and argued that the plaintiffs were seeking a more favorable venue and set of laws. The plaintiffs' side countered that Coupang Inc. is a U.S. corporation listed on the New York Stock Exchange and that executives at the parent company influence decisions at its Korean subsidiary. They argued those ties give the U.S. court jurisdiction over the case. As further grounds for U.S. jurisdiction, they also cited the fact that Coupang Inc. disclosed the Korean subsidiary's data breach to the U.S. Securities and Exchange Commission. Judge Donnelly, however, appeared cautious about whether the court actually has jurisdiction. The judge repeatedly asked about the connection between the data breach and the Eastern District of New York and where the lead plaintiffs reside. The court ordered both sides to submit additional written arguments by Oct. 6. The court is expected to decide afterward whether further hearings are necessary and how the case will proceed. At a press conference before the hearing, Daeryun Law Firm said they will make full use of the proceedings and related documents from Korea. The plaintiffs' representatives also pledged to do everything possible to ensure that the 33.7 million affected Korean consumers can have their rights protected regardless of national borders. Coupang announced in November of last year that personal information belonging to 33.7 million users had been compromised, including their names, contact details, delivery addresses and access codes to residential buildings. The availability of punitive damages in the United States has drawn attention to whether the lawsuit could expose Coupang to greater liability than it would face in Korea. If the U.S. court finds that it lacks jurisdiction, the lawsuit could end before any ruling on the case's merits, including whether Coupang failed to meet its obligations to protect customers' personal information.

FTC raids Coupang again after first attempt comes up empty.

FTC raids Coupang again after first attempt comes up empty. Published: Sept. 1, 2026 - 15:32:32 Updated: Sept. 1, 2026 - 15:42:13 Kan Hyeong-woo Regulator deploys 30 investigators under different law, sidestepping procedural dispute over earlier inspection South Korea's antitrust regulator sent about 30 investigators to Coupang's Seoul headquarters Tuesday, taking the unusual step of reopening its probe under a different law just over a week after the e-commerce giant blocked an earlier inspection. The renewed inspection marks a sharp escalation in the standoff between the Fair Trade Commission and Coupang, with the regulator deploying a large team and reportedly demanding records covering nearly a decade of business activities and transactions. According to industry sources, investigators from the FTC's market monitoring bureau are examining whether Coupang abused its dominant market position or interfered with other companies' business activities in violation of the Fair Trade Act. The FTC previously attempted to inspect Coupang between Aug. 19 and 21 over allegations that the company improperly shifted coupon costs onto suppliers in violation of the Act on Fair Transactions in Large Retail Business. That inspection ended without investigators securing the requested materials after Coupang refused them entry citing how the regulator had failed to provide the legally required advance notice. Under the large retail business law, authorities must notify a company in writing at least seven days before conducting an on-site inspection. Coupang subsequently filed a lawsuit challenging the inspection, claiming that the FTC's failure to provide notice made the action unlawful. A court is scheduled to hear the company's request to suspend the earlier inspection order Wednesday. The FTC's latest move sidesteps that dispute. Unlike the large retail business law, the Fair Trade Act allows authorities to conduct on-site inspections without advance notice. By launching the new inspection under that law, the regulator removed the procedural argument Coupang had used to block the previous attempt. The timing and scale of the operation have drawn attention from industry observers, who described the FTC's response as unusually aggressive. Some questioned whether the expanded probe was partly intended to penalize Coupang for refusing to cooperate with the earlier inspection. The FTC has not publicly characterized the action as retaliatory. The regulator had, however, already signaled that it would take a hard line against the company. At a National Assembly hearing last week, FTC Chair Ju Biung-ghi said the agency would use all available measures in response to Coupang's refusal, including filing a criminal complaint and imposing fines.

Stock price pressure does not undermine long-term value, an analysis of MercadoLibre and Coupang's competitiveness.

Stock price pressure does not undermine long-term value, an analysis of MercadoLibre and Coupang's competitiveness. Buying growth stocks at a discount often yields substantial returns, particularly when their long-term competitive advantages remain intact. MercadoLibre (MELI), the Latin American e-commerce and fintech platform, and Coupang (CPNG), the South Korean e-commerce giant, are currently trading 26% and 68% below their respective all-time highs. However, both companies have seen no erosion of their competitive moats and continue to deliver double-digit revenue growth. MercadoLibre: the long-term play of a Latin American giant. Although MercadoLibre's stock has fallen approximately 26% from its peak, its business performance remains robust. In the second quarter, revenue grew 43% year-over-year on a constant-currency basis. As the leading e-commerce and fintech platform in Latin America, the company has sustained high-speed growth for many years. Its core competitive strength lies in the integration of its online marketplace with a rapidly expanding financial services ecosystem, which encompasses payment and credit tools. In the last quarter, the marketplace segment had 89 million unique active buyers, up 26% year-over-year, while the fintech platform reached 88 million monthly active users, a 30% increase. This deeply integrated model is difficult for competitors to replicate, which explains the company's long-term growth trajectory. The recent stock pullback reflects market concerns over margin pressure, but management has clearly prioritized long-term gains. Investments in free shipping, logistics infrastructure, and credit card operations are aimed at widening the moat and deepening customer relationships, providing a strong rationale for buying on dips. Additionally, advertising revenue surged over 70% last quarter and is poised to become a catalyst for margin expansion over the next decade. At present, the stock trades at a price-to-sales ratio of approximately 2.8 times, below its three-year average of 4.6 times, making the valuation attractive for a company still in a high-growth phase. Coupang: resilience of a leader in a turnaround. Coupang's stock has dropped about 68% from its all-time high in 2021 and is also down 52% from its 52-week peak, primarily due to slowing revenue growth over the past year and a data breach incident that affected user shopping behavior. However, in the second quarter, revenue still grew 10% year-over-year on a currency-adjusted basis. Although this represents a decline from the 14% growth rate in 2025, the fundamentals have not deteriorated. The company is headquartered in Seattle, operates mainly in South Korea, and maintains its dominant position in the local e-commerce market. Building a fast-delivery network in South Korea, where high-rise apartments are densely concentrated, is costly and complex, but Coupang has already completed that build-out, with approximately 99% of orders now eligible for same-day or next-day delivery. Its moat is further reinforced by warehouse automation and the WOW membership program, which integrates benefits such as free shipping, food delivery, and streaming services. Long-term member spending increases significantly over time; members enrolled for more than ten years now spend nearly ten times as much annually as they did in their first year, underscoring platform stickiness and limited alternatives. This also explains the rapid return of users after the data breach - spending by returning users has already surpassed pre-incident levels. In the second quarter, active product e-commerce customers grew 3% year-over-year to 24.7 million. The company is now replicating its South Korean experience in the Taiwanese market, where business growth is approaching the trajectory seen during its early expansion phase in Korea. The current price-to-sales ratio stands at about 0.8 times, roughly half of what it was before the data breach, indicating a low valuation. As the impact of the incident fades and the WOW member base expands, growth is expected to reaccelerate, offering strong return potential over the next decade for investors buying at the current discount.
