South Korean e-commerce giant Coupang, Inc. is facing its most severe crisis of confidence and performance downturn since its 2021 IPO. The lingering effects of a major data breach disclosed late last year continue to erode consumer confidence, compounded by a firm regulatory stance on the company's governance. These factors led the company to report its largest quarterly loss in over four years for the first quarter of 2026 and issue a clear warning that full-year revenue growth will slow further.
The New York-listed company announced on Tuesday an operating loss of $242 million for the January to March period. This represents a sharp reversal from the profit of $154 million recorded in the same quarter a year prior and far exceeded Wall Street's expectation for a loss of approximately $39 million. This loss amount nearly erased half of the company's entire earnings for the full year 2025. The net loss attributable to shareholders widened to $266 million, marking the worst quarterly earnings performance since the fourth quarter of 2021.
Revenue for the quarter increased by 8% year-over-year to $8.5 billion. However, this growth rate represents a significant deceleration from the double-digit growth the company had consistently maintained. Double-digit growth has been a hallmark of Coupang's rise since its debut on the New York Stock Exchange in 2021.
The core trigger for the performance deterioration was one of the most severe e-commerce data breaches in South Korea's history. Regulators previously discovered that a former employee had illicitly accessed personal information from nearly 34 million accounts over several months without detection, affecting approximately two-thirds of the South Korean population. In response to the ensuing regulatory investigations and consumer lawsuits, Coupang launched a compensation plan valued at approximately $1.2 billion in shopping credits. The company stated that these compensation credits were deducted directly from sales, severely impacting revenue and profit for the quarter. The credits expired on April 15.
Chief Executive Officer Bom Kim stated directly on the earnings call, "Due to the incident, the platform lost several months of consumer revenue that should have continued growing. Given this revenue gap, our year-on-year growth rate will be significantly weaker this year, and the scale of business demand required to cover our fixed costs will also fall short of previous expectations."
Simultaneously, growth in Coupang's core Product Commerce segment, which includes Rocket Delivery and Rocket Fresh, continued to lose momentum. Revenue for this segment increased by only 4% year-over-year to $7.2 billion, a sharp drop from the 12% growth rate in the previous quarter. Profit margins also came under pressure, with the gross margin declining to 27% from 29.3% a year earlier. Adjusted EBITDA plummeted by 92% to just $29 million. Total operating expenses reached $8.75 billion, exceeding the quarter's revenue.
Customer metrics also signaled concern. The number of active customers grew by only 2% year-over-year to 23.9 million, representing a net decrease of approximately 700,000 compared to the previous quarter. The expansion of the paid membership ecosystem, long considered its strongest loyalty engine, showed signs of slowing. Industry observers are closely watching whether the data breach and controversies surrounding platform practices have weakened retention among high-frequency users.
As performance pressures mount, regulatory scrutiny continues to cloud the e-commerce giant's expansion path. During the quarter, the Korea Fair Trade Commission issued a key ruling reclassifying Bom Kim as Coupang's actual controller, replacing the previous designation of a corporate entity as the controlling shareholder. The KFTC noted that Kim Yoo-suk, Bom Kim's brother, who holds a vice-president level position, receives compensation comparable to that of a formal executive and has substantive decision-making power over certain business operations. Consequently, Coupang no longer met the criteria for being controlled by a corporate entity. This change comes at a sensitive time for the company and places more direct governance responsibility on Bom Kim personally. In recent years, Coupang and its logistics affiliates have been subject to repeated investigations by regulators and lawmakers over allegations of unfair trading practices, warehouse safety, and delivery worker treatment.
On the earnings call, neither Bom Kim nor Chief Financial Officer Gaurav Anand directly addressed the KFTC's reclassification of the actual controller. However, Bom Kim attempted to reassure investors, stating that consumers' purchasing choices represent votes for the platform and that loyalty and spending trends remain resilient. He emphasized that Coupang plans to respond to challenges by further expanding infrastructure investment, broadening delivery coverage, and enhancing membership benefits, vowing to "spare no effort in creating new WOW moments for customers in selection, price, and service." The company revealed plans to expand WOW-related customer benefits to over $4 billion this year, including free shipping, returns, and streaming-related add-on services.
Anand also sought to alleviate market concerns about slowing growth and increasing external regulatory pressure, stating that short-term disruptions do not alter the company's long-term profit improvement trend. "We believe there is still significant room for improvement in business gross margin and are fully confident in our ability to continue driving the overall gross margin higher," he said.
To boost market confidence, Coupang is aggressively advancing its shareholder return strategy. The company spent $391 million to repurchase 20.4 million shares in the first quarter, and its board approved an additional $1 billion share repurchase program.
Following the earnings release, Coupang's stock fell more than 7% in after-hours trading in the US, extending a decline of approximately 12% since the start of the year, before recovering some losses in the extended session.
