Hunting ten-year five-baggers among great growth stocks — pressing the upside question: "Can it get much bigger?"

• QHow large is its market ceiling? Is it expanding an existing pie, or creating an entirely new market?4/10

  A

  The ceiling is medium-high, but the business is essentially expanding an “existing pie,” rather than creating a new market from scratch. Coupang is digitizing Korean retail and upgrading fulfillment. It is taking long-existing, highly mature shopping demand and moving it onto its own platform through faster logistics and broader supply. This is a classic case of “taking share in an existing market + increasing penetration,” not opening a category that did not previously exist.

  The pie itself is not small, but it has boundaries. According to Morningstar/TMO data cited in the report, Coupang’s share of total Korean retail rose from 6.8% in 2020 to about 15.1% in 2024. It remains the leader and is still taking share. This shows that the ceiling comes from “Korea’s total retail market × online penetration × Coupang’s own share,” while Korea is already one of the world’s most penetrated e-commerce markets, where much of the easy incremental online growth has already been captured. South Korea’s population is about 51 million, and the 33.7 million accounts affected by the data incident are already close to two-thirds of the national population. This indirectly confirms that user coverage is nearing its ceiling, so future growth will rely more on “wallet share per customer” than on “new user acquisition.”

  The only parts that can truly be called “creating new markets” are the Developing Offerings: Eats delivery, Play streaming, fintech, Farfetch luxury, and Taiwan expansion. Yet they are either late entrants in mature tracks dominated by strong rivals such as Naver-Baemin, or attempts to transplant the existing Korean playbook to Taiwan. They are still “replicating an existing model,” not defining a new category, and accounted for only about $1.3 billion of revenue in Q1'26 while still burning cash aggressively. Overall, Coupang lacks the “entirely new market” quality Baillie Gifford values most. Its story is “becoming the strongest player in a known pie”: the ceiling is clear and measurable, but the exponential optionality is limited.

• QCan its revenue at least double over the next five years? Will growth be driven mainly by volume, price, or new businesses?4/10

  A

  A five-year revenue doubling, or about 15% annualized, is challenging and not a base-case outcome; growth is driven mainly by “volume + new businesses,” not price increases. Doubling requires a five-year compound growth rate of about 14.9%, while Coupang’s growth is stepping down: FY2025 net revenue was $34.5 billion, up +14% year over year; by Q4'25 it had fallen to +11% under the reported metric; and Q1'26 slowed further to +8%. In other words, the current actual growth rate is already below the threshold needed for a doubling. A five-year doubling would require either growth to return to the mid-teens, or new businesses to scale enough to fill the gap. Neither should be assumed by default.

  Breaking down the drivers: the mature Product Commerce business, with Q1'26 revenue of $7.2 billion and growth of only +4%, about 85% of revenue, has entered low-single-digit growth. It relies on member repeat purchases, category expansion such as fresh groceries, and advertising penetration. In essence, this is “volume + wallet share.” Price-increase room is constrained by low-priced cross-border pressure from Temu/AliExpress, leaving almost no pricing-power dividend. The real incremental engine is Developing Offerings, with Q1'26 revenue of $1.3 billion, up +28%: delivery, streaming, fintech, Farfetch, and Taiwan expansion. This is growth from “new businesses becoming larger.”

  A rough calculation: if the core business stays at 4–6%, Developing Offerings holds 25–30%, and its revenue share rises from 15% to about 25%, group five-year compound growth would likely land around 10–13%, slightly below the doubling threshold. This means a “five-year doubling” is an upside scenario rather than the base case. The key variables are whether Developing Offerings can sustain high growth without uncontrolled cash burn, and whether core growth can stop falling and recover. Conclusion: the growth direction is real, but the slope is not enough. Doubling requires new businesses to beat expectations and the core to bottom and rebound at the same time. It is possible, but not easy.

• QFive years from now, what will take over as the next growth engine? Does this “second curve” exist today?5/10

  A

  The second curve does already exist today: the Developing Offerings portfolio. But it remains in the “cash-burning seed stage” and has not yet proved it can take over as a profitable growth engine. The successor candidate is not a single business, but a basket: Eats food delivery, Play content streaming, fintech, the acquired Farfetch global luxury platform, and Taiwan market expansion, the first major overseas attempt to replicate the full Korean Rocket model.

  Its “presence” is tangible: Q1'26 revenue was $1.3 billion, up +28% year over year. Its growth rate is seven times that of the core business, at +4%; it contributes about 15% of revenue and is rising. This is exactly the kind of “visible today, with a steeper slope” second curve that Baillie Gifford likes to see. But viewed honestly, it is still two gates away from “taking over.” The first is profit visibility: this segment posted an adjusted EBITDA loss as high as $329 million in Q1'26, widening by $161 million year over year. It was the main reason the group recorded an operating loss of $242 million for the quarter. For now it is both a “growth engine” and a “source of cash drain.” The second is competitive position: delivery must confront the Baemin ecosystem bundled with Naver; Taiwan faces local giants such as momo and Shopee; and Farfetch itself is a distressed asset Coupang bought at the bottom, with an uncertain integration payback period.

  Put differently, the second curve has an “embryo,” but whether it can truly carry the load five years from now depends on at least one sub-business, most likely Taiwan Rocket replication supported by advertising, or delivery reaching a density inflection point, proving unit economics and moving from cash burn to profit contribution. Several analyst estimates suggest EBITDA margin may only return to about 9% in 2027–2028, meaning the second curve’s “handoff” cannot be verified for at least another 2–3 years. For now, the direction is valid, but the outcome is undecided.

• QWhat is its core competitive advantage? Will this moat widen or narrow over the next three to five years?6/10

  A

  The core moat is the self-operated logistics network, Rocket Delivery, built through more than a decade of heavy capital investment. In the core business it is “hard to replicate in the short term,” but over the next three to five years the moat will most likely “hold steady to narrow slightly,” rather than keep widening. The strength of this moat comes from vertical integration: Coupang built a nationwide warehouse and delivery network and directly employs delivery workers. Rocket Delivery covers 90%+ of South Korea’s land area, offers dawn delivery, with orders placed before midnight delivered before 7 a.m. the next day, and same-day delivery. This creates a flywheel of “logistics density → lower unit fulfillment cost → better experience → higher share → still greater density.” Add the stickiness of more than 14 million Rocket WOW paid members and the high-margin advertising business fed by high-frequency retail data. This is what fundamentally distinguishes Coupang from Sea Limited’s asset-light model, and it is the base case for why the stock should not be viewed bearishly below 0.8x PS.

  But when judging whether the moat will “widen or narrow” over the next three to five years, the honest answer is that narrowing pressure is more likely. There are three reasons. First, the moat’s boundary is geographic. It is deep but not wide, almost entirely locked into the single Korean market. Taiwan expansion must rebuild logistics density from zero, so the moat cannot simply be transplanted. Second, competitors are using “ecosystems” to route around a direct logistics battle: Naver intercepts front-end demand through traffic entry points + an open marketplace + NaverPay + bundled Baemin delivery, while Temu/AliExpress use low-priced cross-border supply to erode price bands. Neither needs to replicate Coupang’s warehouse and delivery system to divert demand. Third, and most damaging, the 2025 data incident involving 33.7 million accounts exposed that massive user data is both a moat asset and a liability exposure. Once compromised, it converts into large compensation costs and brand-trust erosion. Trust is the foundation underneath the membership moat. Overall, the logistics barrier is solid in the short term, but the moat’s “width” is being eroded by changing competitive forms and cracks in trust. The rating is “stable, with marginal narrowing.”

• QIf its core business is disrupted, does it have the DNA for self-reinvention? How does it handle mistakes and bad news?4/10

  A

  The “DNA” for self-reinvention has been proved once before, in the shift from cash burn to profitability, but the 2025 data incident exposed a tendency to handle “bad news” through avoidance and delay. That is a clear negative. Start with the positive side: Coupang has historically shown an ability to correct course and reinvent itself. It sustained huge losses in 2021–2023 while the market questioned the heavy-asset model, but it withstood the pressure, pushed logistics density to the inflection point, and delivered GAAP profitability in 2024. That proved management could persist over a long cycle and reverse a strategy that many had written off. This “willingness to go against consensus and endure until results arrive” is evidence of regenerative capacity that Baillie Gifford values.

  But on the question of “how it handles mistakes and bad news,” the 2025 data incident provides a quite negative real-time case that must be included honestly. First, there was delay and underreporting: a former employee, described by Korean media as a former Chinese national employee, used overseas servers and remained inside the system for about five months, with the longest account saying 147 days before detection. Worse, Coupang initially reported only 4500 accounts to authorities, while the final figure was 33.7 million. Korean authorities also accused it of failing to report to KISA within 24 hours and not fully complying with a November data preservation order, resulting in deletion of key access logs. Second, its accountability posture was weak: founder Bom Kim was criticized by public opinion for “avoiding responsibility”. In the end, the Korea business CEO Park Dae-jun resigned to take responsibility, and the parent company’s CAO stepped in as interim successor.

  There were remedial actions as well: a promise of about $1.17 billion in platform coupon compensation, and Palo Alto was brought in to investigate. But overall, the crisis-handling chain of “initially understated disclosure, then being exposed by regulators, with the founder not directly taking responsibility” looks more like crisis PR than candid self-reflection. Conclusion: the strategic reinvention DNA has historical evidence, but the culture of honestly facing bad news is questionable. This dimension is mixed, with a slight negative tilt.

• QDoes management, especially the founder, have a long-term view and deeply aligned interests with the company? Is it willing to sacrifice current profits for the next five to ten years?6/10

  A

  The founder has a long-term view and is clearly willing to sacrifice current profits for the next five to ten years. That is strong. But “deep alignment of interests with the company” deserves a discount: he controls the company through super-voting rights, while his economic interest is only about 9%, so the degree of alignment is lower than the voting control might suggest. Start with the positives. Bom Kim, a Harvard dropout founder, personally built Coupang from zero in 2010 into South Korea’s No. 1 e-commerce company and has long dominated strategy. In 2021–2023, despite market skepticism, he maintained huge capital spending to build a self-operated logistics network, accepting long-term losses to push density to the profitability inflection point, and delivered profitability in 2024. This is the strongest evidence of “sacrificing current profits for the long term.” Today, he is still using a Developing Offerings EBITDA loss as high as $329 million in Q1'26 to continue investing in delivery, Taiwan, and Farfetch. The behavioral consistency of long-termism is strong. Founder leadership over a long period also gives cross-cycle strategic continuity, a trait Baillie Gifford prefers.

  But the “quality” of alignment needs to be separated honestly. According to Korea Herald and others cited in the report, Bom Kim holds about 164.4 million shares, equal to only about 9% economic ownership, yet controls about 74.3% voting power through Class B shares with 29 votes per share. This is a classic “control rights ≫ economic interest” structure: his “wallet alignment” with the company’s fate is only 9%, far below what his influence implies. Minority shareholders have almost no check on major capital allocation, acquisitions such as the bottom-fishing Farfetch deal, or governance accountability. The downside of this double-edged sword became visible in the public criticism that the founder “avoided responsibility” during the data incident, and in the local CEO resigning instead. Controlling the company without fully bearing responsibility is the real governance risk of this structure.

  Conclusion: the long-term view and “willingness to burn cash for the future” both score full marks, but “deep interest alignment” is penalized by the mismatch between 9% economic ownership and 29x super-voting rights. Management is long-termist, but not the type whose interests are highly in the same boat as all shareholders.

• QIf it disappeared tomorrow, how much would customers miss it? Is its growth model sustainable and not dependent on harming society or inviting regulatory backlash?5/10

  A

  Its indispensability is strong. If Coupang disappeared tomorrow, 14 million paid members would miss it badly. But on whether its growth model avoids harm to society and regulators, the 2025 data incident gave a clear negative warning that must reduce the score. Start with indispensability: Coupang turned “order at dawn, receive before 7 a.m. the next day” into everyday infrastructure for Korean consumers. It has more than 14 million Rocket WOW paid members and an account base covering nearly two-thirds of South Korea’s population, with membership bundling delivery, fresh groceries, food delivery, streaming, and other benefits. If it disappeared, fulfillment speed across Korean retail would regress overall, and substitution costs would be extremely high. This is a product that would truly “be missed,” meeting the Baillie Gifford standard for indispensability.

  But the second layer of assessment, whether growth is sustainable and does not harm users, labor, or regulators, shows real blemishes in Coupang’s record. First, the failure of data governance directly harmed users: the names, phone numbers, emails, and delivery addresses of 33.7 million customers were leaked. The company initially disclosed only 4500 accounts, was accused of failing to report within 24 hours and deleting key access logs. This is a classic regulatory risk from treating user data as growth fuel without fulfilling the duty to protect it. Second, regulatory backlash is already real: under Korea’s data protection law, fine exposure is 3%–10% of revenue, or more than $800 million, and it has developed into the unusual situation of large U.S. investors invoking the Korea-U.S. FTA to initiate ISDS international arbitration. Regulatory and legal risks have risen across the board. Third, labor intensity for directly employed delivery workers, Coupang Friends, has also long been a social controversy in Korea.

  Balance is also needed: the leak did not involve financial information, and the company later promised $1.17 billion in coupon compensation. But overall, the product’s indispensability is A-grade, while the “does not harm” quality of the growth model is pulled down by the data incident, labor controversy, and regulatory confrontation. The positives and negatives are clear, with a net rating slightly below neutral.

• QWhat are the unit economics of this business, in gross margin and incremental returns? Do they improve or worsen as scale increases? Where does the money it earns go?4/10

  A

  The unit economics are “structurally thin, but improvable with scale”: gross margin is low, incremental returns rise gradually through logistics density and high-margin advertising, but they have now been pushed back down by one-off events. The money earned is mainly being reinvested into Developing Offerings and the fulfillment network. Start with gross margin. Coupang is a heavy-asset, self-operated retailer that buys inventory and builds its own warehouse and delivery system, so its gross margin is inherently lower than that of asset-light platforms. Q4'25 gross margin fell to 28.8%, down another 248bps year over year, and both the report and bearish Bernstein SocGen specifically cited “rising first-party inventory costs causing margin deleverage”. Compared with Sea Limited, which has scaled profitably and generated FY2025 net income of $1.6 billion, Coupang’s earnings quality is clearly more fragile.

  But the question of whether things “improve or worsen as scale increases” needs to be layered. The answer is “the core business improves, Developing Offerings temporarily worsen, and one-off events have interrupted the trend.” Product Commerce has a positive flywheel: greater logistics density lowers unit fulfillment cost, and high-margin advertising penetration adds real long-term margin leverage. Profitability in 2024 was evidence that incremental returns had turned positive. The problem lies in two areas. First, Developing Offerings are diluting returns in reverse: Developing Offerings posted an adjusted EBITDA loss of $329 million in Q1'26, widening by $161 million year over year, so incremental investment is not yet earning a return. Second, the data incident, through coupons and capacity inefficiency, pushed the quarter into an operating loss of $242 million and TTM net income negative at −$165 million.

  Where the money goes: operating cash generation, FY2025 operating cash flow of $1.8 billion and net cash of about $4.0 billion, is almost entirely reinvested into fulfillment-network capex, cash burn in Developing Offerings, Taiwan expansion, and temporary coupon compensation. There are no dividends or buybacks; this is a classic “reinvest everything for growth” model. Conclusion: the unit-economic foundation is thin but has a path to improvement. The key question is whether the core flywheel can cover the cash drain from Developing Offerings. That is the root of today’s low profit visibility.

• QWhat conditions must hold simultaneously for it to rise fivefold in ten years? Are these conditions realistic? What expectations are embedded in today’s share price?4/10

  A

  For the stock to rise fivefold in ten years, three things must happen at the same time: “structural delivery of profitability + renewed growth acceleration + a significant valuation multiple expansion.” The difficulty is high, making this an upside scenario rather than the base case. The helpful part is that today’s share price of about $15.85 already embeds quite low expectations, offering some margin for error. Quantify the target first: rising fivefold from the current price of $15.85 and market cap of about $28.45 billion would imply a market cap of about $142 billion and an annualized return of about 17.5%, far above the natural growth rate of the Korean retail market. To achieve it, at least the following conditions must stack together:

  First, profitability must move from “interrupted” to “structurally scaling.” Bullish estimates that EBITDA margin returns to about 9% in 2027–2028 and adjusted net income grows about 7 times by 2028 must actually materialize, and Developing Offerings, with current EBITDA loss of $329 million, must turn from cash drain to profit contributor. Second, revenue growth must stop falling from today’s +8% and recover to the mid-teens, with successful Taiwan Rocket replication and delivery reaching density. Third, data-incident exposure must clear and prove controllable: 3%–10% of revenue in fines, or more than $800 million, must land without being fatal, and U.S. ISDS arbitration and shareholder class actions must not evolve into continuing liabilities. Fourth, valuation must recover from 0.8x PS toward a growth-stock range of 1.5–2x. All four need to move in the right direction; missing any one makes a fivefold return hard. Realism can only be described as “possible, but requiring many variables to align at once.”

  What today’s share price embeds: 0.8x PS, near the 52-week low of 14.92–34.08, and materially below the 12-month average of 1.49x, with TTM net income already negative. This means the market is essentially pricing only the “core-business cash cow,” assigning almost no premium to Developing Offerings or profit recovery, and partly pricing in penalties and growth deceleration. That is a “pessimistic assumption.” The benefit is that if the company merely returns to profitability and stabilizes growth, without needing a fivefold narrative, the sell-side consensus target of $26.59, about +68%, could be realized. Conclusion: a fivefold return over ten years needs a near-perfect multi-variable alignment and should not be the base expectation; but the low-expectation starting point makes “doubling-level” neutral returns more realistic.

• QWhy has the market not recognized all of this yet? Is it failing to understand, dismissing it, or not looking far enough ahead? What would become the “narrative inflection point”?4/10

  A

  The market is not “failing to understand” or “not looking far enough ahead”; it “does not dare to trust it.” It clearly sees Coupang’s moat and long-term potential, but the data incident, negative profitability, and regulatory overhang have made investors unwilling to pay a premium before the dust settles. This is closer to “dismissing the short term + waiting for confirmation” than to a cognitive blind spot. The evidence is the disagreement itself: 17 analysts have an average target price of $26.59, implying about +68%, and the rating remains Buy; bulls point to $29–40, while bearish Bernstein SocGen cut its target to $12–15 and maintained an “underperform” view. When bull and bear target prices differ by more than threefold, the market is not short of information; it lacks certainty. This is a typical “event overhang + visibility vacuum,” not a case of long-term value being ignored.

  Three real, not imagined, discount factors are weighing on the share price. ① Profitability has just been interrupted: TTM net income has turned negative at −$165 million, and Q1'26 operating loss was $242 million, so quantitative and passive funds will first avoid loss-making stocks. ② The regulatory tail is unquantifiable: fine exposure of 3%–10% of revenue, U.S. ISDS arbitration, and shareholder litigation all have uncertain size and timing, and the market habitually applies the steepest discount to “liabilities that cannot be priced.” ③ Growth has decelerated: from +14% all the way down to +8%, shaking the foundation of a growth-stock valuation. These are reasonable reasons to “dismiss the short term,” not foolish failure to understand.

  What would become the narrative inflection point: first, regulatory fines and litigation amounts land within a bearable range, converting the “unquantifiable tail” into a “known one-off cost.” That is the strongest de-risking event. Second, Q2/Q3 2026 operating losses narrow, quarterly profit returns to positive, and the loss-reduction inflection in Developing Offerings is confirmed. Third, share remains stable despite competition from Naver-Baemin and Temu. The report’s “Watch” rating is based on this. Once these items materialize, valuation has room to recover from 0.8x PS toward 1.0–1.2x. Conclusion: the market can see the greatness, but before the data incident clears it chooses to “deduct points first and add them back later.” The inflection point depends on the speed of uncertainty clearing.
