Coupang Swings to a Q3 Operating Loss as Sales Grow 11% in Constant Currency

Coupang, the company behind South Korea's Rocket Delivery service, increased sales in the third quarter of 2026 and still lost money on its core operations. The New York-listed e-commerce company reported net revenue of $9.96 billion for the three months ended Sept. 30, up 7% from a year earlier and up 11% on a constant currency basis. But it posted an operating loss of $450 million, compared with an operating profit of $162 million in the same quarter of 2025.

The biggest single hit came from a July fire at a leased fulfillment center in Incheon, west of Seoul. Yet even after stripping out the fire, Coupang was still in the red. This post walks through what the company does, how much the business grew, how big the fire cost was, and why costs outran sales.

What Coupang is

Coupang is often described as the Amazon of South Korea. Its parent company, Coupang, Inc., is headquartered in the United States and trades on the New York Stock Exchange under the ticker CPNG, but most of its sales come from Korea. The core business, which the company calls Product Commerce, combines the goods it buys and resells itself, its online marketplace for third-party sellers and its fresh grocery delivery. A second segment, Developing Offerings, groups newer businesses such as the Coupang Eats food delivery app, the Coupang Play streaming service, Rocket Delivery in Taiwan and the luxury fashion platform Farfetch.

Because Coupang reports in US dollars while earning mostly in Korean won, currency moves matter. Korean media converted the third-quarter figures at the quarter's average rate of 1,427.52 won per dollar, which puts revenue at roughly 14.22 trillion won (about $9.96 billion) and the operating loss at about 642.3 billion won.

How much sales grew

Revenue rose 7% in dollar terms and 11% in constant currency, beating the company's own earlier guidance of 8% to 9% constant-currency growth. The gap between the two growth rates comes from the weaker won: when the won loses value against the dollar, the same won-denominated sales translate into fewer dollars.

Product Commerce revenue was $8.37 billion, up 5% in dollars and 8% in constant currency. Developing Offerings grew faster, with revenue of $1.59 billion, up 23% in dollars and 27% in constant currency. That newer segment still lost money, but its adjusted EBITDA loss narrowed by $23 million from a year earlier to $269 million.

Constant currency growth: a growth rate calculated as if exchange rates had not changed from the prior-year period. It shows how much the underlying business grew without the effect of currency swings.

The Incheon warehouse fire

In July 2026, a fire significantly damaged one of Coupang's leased fulfillment centers in Incheon. Coupang booked fire-related losses that cut its third-quarter operating result by $248 million. Part of that cost landed in cost of sales, which is why gross margin fell to 25.7%, down 3.64 percentage points from a year earlier. Excluding the fire, the company said gross margin would have been 26.7%.

When Coupang reported second-quarter results, it had estimated the fire losses at about $246 million, covering the book value of inventory and equipment at the site and payments it owed to sellers whose goods were stored there, according to Korean press reports. Those losses have now flowed through the income statement.

Why the loss remained without the fire

Even excluding the fire, Coupang's operating loss was $202 million. In other words, the company would have lost money in the quarter without the blaze.

The income statement shows why. Cost of sales rose to $7.40 billion, or 74.3% of revenue, up from 70.6% a year earlier. Operating, general and administrative expenses climbed 17.7% to $3.01 billion, far faster than the 7% rise in revenue. The company kept less from each sale and spent more to run the business at the same time.

Product Commerce, the profit engine, felt it most. Its adjusted EBITDA fell 45% to $385 million, and its margin dropped to 4.6%. The net loss attributable to shareholders was $501 million, or 28 cents a share. Excluding the fire, the net loss would have been $321 million.

For the first nine months of 2026, Coupang's operating loss reached $1.25 billion, compared with an operating profit of $465 million a year earlier. Korean media noted it was the third straight quarterly operating loss.

Operating income: revenue minus the cost of goods and the expenses of running the business. It excludes items such as interest and currency gains or losses, so it shows how profitable the core business is.

Customers and the outlook

The customer numbers moved in the other direction. Product Commerce active customers rose 2% to 25.2 million, and revenue per active customer increased 3% to $332. Coupang also bought back 12.7 million Class A shares for $201 million during the quarter.

On its earnings call, the company projected fourth-quarter revenue growth of 13% to 14%, according to Korean press reports. The next quarters will show whether that growth can turn back into profit, whether the cost ratio and operating expenses start rising more slowly than sales, and how any insurance recovery tied to the fire is recorded.

Key takeaways

Coupang's third-quarter revenue grew 11% in constant currency, but the company swung to a $450 million operating loss. The Incheon fire accounted for $248 million of the hit, and rising costs left a $202 million loss even without it. More customers are shopping on Coupang, but the company is keeping less from each sale.
