Shein: The Vietnam Retreat Shows The Core Problem, And The $30 Billion IPO Target Does Not Solve It

Shein is about to go public after four aborted listing attempts, and the prospectus tells you exactly why the stock is a hold. The company's attempt to reroute its supply chain through Vietnam never materialized into anything operational. More than 90% of its revenue still flows through Chinese warehouses. The company swung to a $99 million loss in the first quarter of 2026 after years of profitability. And it's asking investors to pay up to $40 billion for a business whose core model — duty-free parcel shipping from China — has been dismantled by policy changes in both the U.S. and Europe. The Vietnam warehouse was supposed to be the answer to that problem. It wasn't.

The setup makes sense in retrospect. In early 2025, Shein was one of the companies most exposed to the Trump administration's decision to eliminate the de minimis exemption — the policy that let packages under $800 cross the U.S. border duty-free. Shein had built its entire economics around that loophole. Over 90% of its revenue in 2025 came from goods shipped directly from Chinese warehouses to overseas shoppers. When that exemption was scrapped in May 2025, Chinese-origin shipments suddenly faced tariffs ranging from 10% to 87.5%.

Shein's response was to lease a 15-hectare warehouse near Ho Chi Minh City, Vietnam — its first facility in the country. The idea was straightforward: if the goods ship from Vietnam instead of China, they still qualify for duty-free treatment under the $800 threshold. The facility is in a good spot, next to Vietnam's largest import port from China and a major export gateway to the United States. Shein even offered suppliers incentives to relocate, including procurement price increases of up to 30%.

Then China told Shein to halt its supply chain diversification. Beijing, trying to stem the flow of manufacturing departures during a tariff war, asked the retailer to slow its Vietnam push. Around the same time, Shein realized its Singapore-headquartered structure was blocking the China Securities Regulatory Commission's approval for a Hong Kong listing. So it pivoted back: considering a return to China as its operational base, and in February 2026, founder Sky Xu pledged over 10 billion yuan ($1.45 billion) to strengthen its supply chain in Guangdong province, supporting roughly 10,000 suppliers and 600,000 jobs.

The Vietnam warehouse experiment was never abandoned because it was a terrible idea geographically. It was abandoned because the economics never worked at scale and Beijing wouldn't let it work politically. Shein's IPO filing, released on July 26, confirms the reality: the company's supply chain remains "anchored by a central logistics hub in China." Products stored in Chinese mainland warehouses represented over 90% of net revenues in 2025. The Vietnam facility is not mentioned as a material operation in the prospectus.

What the prospectus does reveal is the damage the tariff shift has already done. In Q1 2026, Shein swung to a $99 million net loss from a $395 million profit in the same quarter a year earlier. A $328 million one-time accounting charge on convertible preferred shares accounts for part of the swing, but the underlying business deterioration is the larger story. U.S. revenue fell 14.3% to $2.04 billion in Q1, as the company raised prices to offset tariffs. Fulfillment costs rose to 47.7% of net revenue, up from 45.6% across 2025. Operating margins compressed to 2.9% in Q1, down from 3.9% a year earlier.

The full-year picture is similarly decelerating. Revenue grew just 8% to $41.8 billion in 2025, a sharp slowdown from the 20.7% growth posted in 2024. Full-year net income fell 38.7% to $2.06 billion. Active customers grew to 281 million in the 12 months through March 2026, up from 241 million previously, but order frequency stayed flat at about four purchases per year. Growth is now entirely dependent on adding new shoppers, and customer acquisition costs are rising. Shein's share of U.S. apparel spending peaked at about 5% in Q1 2025, turned negative year-over-year by Q4 2025, and continued to decline in 2026. The steepest losses are among 18-to-34-year-olds — the demographic that built the brand.

Europe is the next problem. The EU imposed a 3-euro customs charge on low-value e-commerce imports earlier this year, and Europe supplied nearly one-third of Shein's 2025 revenue. The prospectus warns the EU measure's impact "could be generally in line with or exceed the impact observed in the U.S." That is a meaningful headwind on the company's second-largest market.

So here is the core question for the IPO: what is this company worth at $30 billion to $40 billion when its margins are structurally under pressure in both of its largest markets?

Shein's valuation has cratered from $98.2 billion in 2022 to $64 billion by 2024. The $30-to-$40 billion target for this August offering represents a markdown to roughly 0.7 to 1.0 times trailing revenue. On the surface, that doesn't look expensive for a company with 281 million active customers and 70.4% gross margins in Q1 2026. But gross margin expansion came partly from a shift toward a third-party marketplace model, which records only service fees rather than full product revenue. That inflates the margin percentage while compressing the actual dollar value of each transaction. Meanwhile, net margins sit around 4.9% on an annualized basis — far below Inditex (Zara), which earns above 15% with inventory positioned closer to European consumers.

The Vietnam warehouse was a symptom, not a cure. The underlying problem is that Shein's ultra-fast fashion model — producing small batches of 100 to 200 units, testing demand in real time, and replenishing winners within five days — depends on a hyper-efficient, China-anchored supply chain of roughly 7,500 small and medium-sized manufacturers. Moving that ecosystem to Vietnam, or anywhere else, is not a warehouse lease. It's a multi-year retooling project that Shein has not committed to, in part because Beijing wouldn't allow it.

The $1.45 billion investment in Guangdong is a political reconciliation play. It also acknowledges a practical reality: the China supply chain is the only one that can sustain Shein's operational model at this volume. The company is choosing to absorb tariff costs, raise prices, and hold local inventory in key markets rather than rebuild its manufacturing base overseas. It acquired Everlane for $100 million in May 2026, likely to gain a U.S.-founded label it can use to market domestically and partially offset the tariff narrative. But these are tactical patches on a structural problem.

The catalyst clock is clear. The Hong Kong IPO is expected as early as mid-August. Pre-deal investor meetings have already started. Goldman Sachs, Morgan Stanley, and JPMorgan Chase are joint sponsors. China's securities regulator approved the listing on July 10. The company is positioning this as the end of a four-year listing odyssey. For investors, the question is whether the first quarter of the post-IPO era will be defined by the margin destruction that's already visible or by the multi-year rebuild that lies ahead.

The biggest risk is that the IPO locks in a valuation that assumes tariff pressure is temporary while the evidence points to something more persistent. The U.S. de minimis exemption is gone. The EU charge is new and expanding. Vietnam itself faces a 10% baseline tariff on exports to the U.S., with the potential to rise to 46% if no agreement is reached. Shein's own prospectus identifies its China-based sourcing model as a "strategic vulnerability."

I'm labeling this a hold at the current IPO target range. The valuation markdown from $98 billion to $30-to-$40 billion reflects real deterioration. But the prospectus also reveals a company whose unit economics have been broken in its two biggest markets, whose fastest-growing demographic is slipping, and whose diversification experiment into Vietnam never moved beyond a single warehouse lease. At $40 billion, the stock is pricing in a recovery that has not begun. At $30 billion, it's closer to defensible but still requires the assumption that Europe's margin impact won't exceed what the U.S. already delivered and that the company can grow purely through customer acquisition while fulfillment costs eat nearly half of every dollar.

What would change my view? A post-IPO quarter showing gross margins holding above 65% while fulfillment costs decline below the 47% Q1 level. Evidence that the Vietnam facility or a new regional warehouse network is absorbing a material share of shipments. Or a valuation that drops below $25 billion, at which point the margin pressure is already reflected and the 281 million active customers represent a platform worth rebuilding around. Until then, the Vietnam retreat tells you everything you need to know: the problem isn't geography. It's a business model that can't reroute fast enough.
