Long-Term Value Investment Research on BYD

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

• QHow high is its market ceiling? Is it expanding an existing pie, or creating a completely new market?6/10

  A

  Conclusion first: by "sales/scale," BYD's ceiling is extremely high. It is not creating a new market from scratch, but standing inside the enormous existing global auto market, pushing the shift from fuel to electric, and taking share during that migration. In the Baillie Gifford (LTGG) framework, this is a typical case of "reshaping + replacing an existing mega-market," not "creating a new market." But from an upside lens, one key asymmetry appears: the ceiling is frighteningly high by "units," yet the "profit pool" is a low-margin red ocean. A high ceiling does not mean a large profit space for shareholders. This is exactly what this question should press on.

  How large is this pie, and how far has the migration progressed?

  First size the "pie." Global annual new-car sales are roughly 90 million units (about 91.7 million in 2025), a huge stock market that repeats every year. The electrification migration: IEA data show global EV sales first exceeded 20 million units in 2025, accounting for about 25% of new car sales, and are expected to rise to about 23 million units and 28% in 2026; China is moving faster, with EVs accounting for more than 60% of new car sales in April 2026. In other words, global electrification is roughly only 1/4 complete, with 3/4 of the fuel-car stock still waiting to be replaced. This is the quantitative foundation behind the report's repeated phrases "the long-term electrification trend is clear" and "long-term demand is strong." BYD sold about 4.6 million units in 2025. Even as the global EV sales champion, it held only about 19% of global plug-in sales and about 15.7% of BEV sales. In a migration wave that still has room to multiply, the pure share × penetration runway is indeed long. Honestly, this is neither "expanding a small pie" nor "creating a new market"; it is competing to be the share winner in an already huge pie undergoing a generational technology replacement.

  Why "high ceiling" must be discounted for this company

  The Baillie Gifford framework looks for "great growth stocks that can rise 5x in ten years." A large TAM is not enough; the question is whether the market can convert into shareholder value. Here lies the problem: the finished-vehicle profit pool is inherently thin and has become thinner over the past two years. At the industry level, global OEMs' average operating margin in 2025 was only about 2.7%, with Q4 falling to 3.6%, more than halved from the 2021 peak; component suppliers have instead consistently outperformed and stayed around 6.9%. In other words, the fatter profit in the auto value chain is increasingly captured by upstream/components rather than automakers. BYD is not immune: the report's numbers are clear: 2025 gross margin fell from 19.44% to 17.74%, net margin was only 4.1%, net profit attributable to shareholders fell about 19% YoY, and in 2026Q1 revenue fell -11.82% while net profit attributable to shareholders fell -55.38%. This is why the report calls it an "excellent company in a difficult industry," not a "light-asset king in a good industry." Sales and industry position can rise without simultaneous increases in margins and free cash flow (2025 free cash flow even turned negative at about -RMB 97.7 billion).

  Where is the "new market," and should it be counted in the ceiling?

  BYD does touch several adjacent new markets beyond the existing auto pie: energy storage (an extension of the battery business), electronics OEM/handset components (19.31% of 2025 revenue), and semiconductors (IGBT/power devices for self-supply). These are closer to "creating/positioning in adjacent new markets" and can theoretically open a second profit pool, while also forming part of its vertical integration moat. But honestly: their shares of total revenue and profit are still small, while automobiles still contribute about 80.68% of revenue. In the short term they cannot support an independent valuation narrative. The real market ceiling in this question is still 90% about "global auto electrification replacement."

  Summary (answer to the upside lens): if the question is only "can it sell more cars," the answer is yes. The runway by unit volume is very long, and 3/4 of penetration remains; this is the premise for a blue-sky case. But the Baillie Gifford question does not stop at volume. It then asks: "how much money can this enormous pie leave for shareholders?" Finished-vehicle manufacturing is a structurally low-margin, price-war-heavy business whose profit pool is being siphoned upstream. So BYD's ceiling is a combination of "high volume + thin profit": growth space by volume is very large, but value capture by profit is suppressed by the industry's nature. This echoes the report's "Watch" rating and its core tension of "scale keeps expanding while shareholder returns are under pressure." BYD is not monopolizing a new continent; it is competing on an old continent undergoing regime change, still crowded and bloody, trying to be the survivor that can turn share into profit. Whether that happens is the real divide for a ten-year 5x outcome.

• QCan its revenue at least double over the next five years? Will growth be driven mainly by volume, price, or new businesses?5/10

  A

  Conclusion first: doubling revenue within five years, from about RMB 804.0 billion in 2025 to about RMB 1.6 trillion, equivalent to about +15% annual compound growth, is not impossible, but it is far from natural. It depends heavily on the single bridge of "whether overseas expansion can deliver high-speed volume for several consecutive years," while the domestic base is still shrinking in the short term. Under a Baillie Gifford framework that looks from an upside perspective for multi-bagger long-term compounders, BYD has a revenue story, but its certainty is much weaker than during the previous five years of rapid growth. The growth engine ranking is clear: volume, especially overseas, > price, through premiumization, > new businesses, such as energy storage/electronics.

  First, why the short term is a headwind. The report already points out that 2026Q1 revenue fell 11.82% YoY and net profit attributable to shareholders fell 55.38% YoY. This is not a small fluctuation. Latest monthly data confirms the same thing: BYD's cumulative NEV sales in January–May this year were about 1.405 million units, still down 20.32% YoY. May was only the "first YoY increase in eight months," and it was barely positive at +0.26%. In other words, domestic price wars have held down the base. To double in five years, the first year is filling a hole rather than taking off.

  Driver one: volume — overseas is the real engine and the decisive factor in the doubling script. This is the strongest bullish evidence. The report records 2025 overseas sales of 1.046 million units, +150.7% YoY, with finished-vehicle exports exceeding 1 million and coverage of 119 countries. In 2026, this momentum is still accelerating: May overseas sales reached a record 160,644 units, +80% YoY, accounting for 42% of monthly NEV sales; overseas sales in the first five months were already about 616,000 units, up about 65% YoY. Management is also pressing hard: the 2026 overseas target has been raised from 1.3 million units at the start of the year to 1.5 million units (+15%). Overseas unit pricing is generally higher than domestic pricing, so "overseas volume" is a dual positive for revenue through both volume and price. But this is also the biggest vulnerability: the report repeatedly warns that overseas expansion requires local factories, channels, brand investment, and tariff absorption, with long capital recovery cycles. If European tariffs, Southeast Asian/Latin American localization costs, or policy reversals in major markets consume the increment, the doubling script stalls.

  Driver two: price — premiumization is lifting ASP, but not yet to the point where consumers "recognize only the brand, not the price." The report judges BYD to be a "value for money + technology reliability" brand in the mass market, while premium pricing power remains under construction. Recent progress is positive: in 2025, Denza, Yangwang, and Fangchengbao sold about 397,000 units combined, +109% YoY, and the structure is moving upward, gently lifting unit ASP. But honestly, the main growth comes from Fangchengbao's "affordable luxury" around the RMB 200,000 price band, while true premium traction above RMB 300,000 remains weak. So "price" is a positive factor and important for margin repair, but it cannot support the doubling scale alone.

  Driver three: new businesses — energy storage is a real second battlefield, but still small in mix. In 2025, BYD's energy storage system shipments exceeded 60 GWh, overtaking Tesla to become the world's largest energy storage system integrator, with about 13% share, again relying on the vertical integration cost advantage of its self-developed Blade LFP batteries. Together with handset components/assembly (19.31% of 2025 revenue), new businesses are meaningful incremental buffers, but they are not large enough in the short term to independently push the whole company to double.

  Two final risks in interpretation must be made clear: First, "revenue doubling" does not equal "profit doubling". The report shows 2025 gross margin already fell from 19.44% to 17.74%, and free cash flow turned negative at -RMB 97.7 billion. Overseas volume requires local capex at the same time, so larger revenue may not bring proportional profit or shareholder free cash flow. This is exactly why the report gives "Watch" rather than "Buy." Second, doubling in five years is an upside case, not the base case. The report's neutral DCF assumes 8% owner-earnings growth over the next five years, corresponding to fair value of HK$100–125. To reach revenue doubling, overseas volume must deliver +50%-type growth for several years and margins must not be dragged down by tariffs and price wars. The path is visible, but it should be treated as an optimistic script requiring continued validation of overseas sales and overseas margins, not a locked-in outcome.

• QAfter five years, what will take over as the next growth engine? Does this "second curve" exist today?4/10

  A

  Conclusion first: a second curve does have an outline today, but most candidates have not truly "taken over." They look more like extensions or by-products of the first curve, automobiles, than independent new profit engines. The direction with the most potential to be a truly independent second curve is energy storage, already the world's largest by scale, but it is still not separately disclosed in the financials as a meaningful profit line. The other candidates — overseas localization, premiumization, and intelligent driving — are essentially still about "making the car business more valuable," not "opening a new business." The report's characterization of BYD is exactly this: it is an "excellent company in a difficult industry," with scale and cost moats widening, but whether growth can turn into shareholder cash returns is the valuation key (reasonable range HK$100–125, rating Watch).

  Below are the candidate curves, judged by "does it exist today / can it grow into meaningful profit":

  ① Energy storage (most like a real second curve, but financially unclear) This is the only direction where the business scale is already independently significant. In 2025, BYD overtook Tesla to become the world's largest energy storage system integrator, with about 13% global share (Tesla about 10%); annual energy storage system shipments exceeded 60 GWh, ranking first, relying on the same Blade LFP batteries used in vehicles. This is vertical integration spilling over. But a cold-water point: BYD still has not separately broken out energy storage as an independent revenue/profit line in the annual report. It is included in the report's "automobiles, automobile-related products and other products" segment, which accounts for 80.68% of revenue. In other words, energy storage is "already number one globally by scale," but "not yet proven as to how much independent profit it contributes." The Baillie Gifford question — "can it grow into a meaningful profit source?" — cannot yet be answered.

  ② Overseas localized manufacturing (from "exports" to "global capacity," but with a long return cycle) Finished-vehicle exports exceeded 1 million units in 2025, and overseas sales were 1.046 million units (+150.7%), facts confirmed by the report. The next step is turning "exports" into "local production": trial production at the Hungary plant in 2026Q1 and full production before Q2, the Manisa plant in Turkey coming online in mid-2026, and Brazil and Indonesia plants also ramping in 2026, with initial single-plant capacity often around 150,000 units. This can bypass EU tariffs and improve overseas pricing power. But is it a "second curve"? Strictly, no. It is still the first curve of selling cars, only in a higher-margin and more tariff-resistant form. The report repeatedly stresses that local factories, channels, and branding all require cash and long payback cycles; this is part of why 2025 free cash flow turned negative (-RMB 97.7 billion). Whether it can lift overall margin must be proven by future financial statements.

  ③ Premiumization (Yangwang/Denza/Fangchengbao: making progress, but not yet mature) This improves "profit quality" rather than opens a new track. In 2025, among the three premium brands, Fangchengbao reached 31,000 units in October, Denza about 10,000 units, while Yangwang remained only a few hundred units monthly. The report is restrained: premiumization "is trying to happen, but is far from consumers recognizing only the brand and ignoring price." So premiumization today has an outline and progress, but cannot yet support an independent profit curve. It is more like improving the gross margin of the first curve.

  ④ Intelligence/intelligent driving ("God's Eye" across the lineup — currently a cost item, not a revenue item) BYD is democratizing advanced driver assistance. God's Eye has been rolled out across almost the full lineup, with 2.3 million+ vehicles on the road by November 2025 and about 190 million km of data generated daily, and plans about USD 14.3 billion in intelligent-driving investment, with self-developed chips also released in May 2026. The key is monetization: unlike Tesla selling FSD as an expensive option, BYD makes intelligent driving a no-extra-cost standard feature to sell cars. That means intelligent driving today is a cost/moat investment that improves product competitiveness, not a separately monetized software revenue curve. It may eventually translate into data/software value, but that is a more distant story and currently sits on the expense side.

  How Baillie Gifford would view it / reminder for readers The heart of LTGG is asking "what takes over after five years, and why has the market not realized it?" Combining the four points above: BYD does not lack extension growth points — overseas, premiumization, energy storage, and intelligent driving are all growing — but it lacks a non-auto second curve already proven by the financial statements to contribute large independent profit. Energy storage has scale but opaque profit; intelligent driving is still cash burn; overseas and premiumization are still essentially automobiles. In the optimistic view, this is precisely what the market may not have fully priced: if energy storage can show meaningful profit over the next 3–5 years and overseas localization lifts gross margin, the report's optimistic range of HK$150–190 can hold. But the report also states the downside clearly: if these curves fail to become meaningful profit sources and growth keeps consuming cash, BYD will be re-rated from a "growth stock" to a "mature automaker," with about 40%–55% permanent capital loss risk. So "the second curve has an outline today" is true, while "it can carry the company tomorrow" remains a hypothesis needing validation, not a fact.

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

  A

  Conclusion first: BYD's core competitive advantage is cost and scale from vertical integration: self-developing and self-producing Blade Batteries, motors, electronic controls, chips, and even the e-Platform 3.0 vehicle platform, then combining that with the scale of ranking first globally in NEV sales for four consecutive years, more than 120,000 R&D engineers, cumulative R&D investment above RMB 180 billion, and the first year of exports above 1 million units. The report's characterization is important and restrained: the moat is "strong, but differentiated" — cost, scale, and globalization are widening, while pricing power in the domestic mass market is narrowing. So the right answer is not a binary "widening or narrowing," but both directions happening at once. Over the next three to five years, the net judgment depends on whether the widening parts outrun the narrowing parts.

  First, why it is "widening." Mainly four things:

  • Overseas scale. In 2025, overseas sales were 1.046 million units, +150.7% YoY, covering 119 countries and regions, and overseas revenue already reached 38.65%. Overseas unit profitability is usually higher than inwardly competitive China. If scale spreads across Europe, Latin America, and Southeast Asia with local factories, it can both spread costs and improve profit structure.
  • Premiumization. Denza, Yangwang, and Fangchengbao are moving upward. The upgraded Denza N9 even achieved an about 5% increase in starting price, showing brand premium is being built little by little, although the report honestly says it is still far from "consumers recognizing only the brand and ignoring price."
  • Intelligence. This is the most concrete new increment after the report's base date (2026-05-20): BYD has rolled out "God's Eye" across the lineup, with cumulative equipped vehicles above 2.56 million by the end of 2025, introduced China's first 4nm in-house intelligent-driving chip, Xuanji A3, and even promised to bear full compensation liability for accidents caused by urban navigation assistance. This signals vertical integration extending from "electric powertrain hardware" to "software + chips."
  • Energy storage. It uses the same Blade LFP battery system. In 2025, BYD overtook Tesla to become the world's largest energy storage system integrator (about 13% share, 60+ GWh shipped). This is the spillover benefit of vertical integration: the same battery capacity can feed both cars and the grid.

  Now, why it is "narrowing." The report is clear: the moat is "overall stable and locally widening, but not automatically widening." Specifically:

  • Domestic homogenized competition. China has moved from a high-growth blue ocean to a high-penetration red ocean (EV penetration already close to 55% in 2025), and all competitors are cutting prices. The report judges BYD's pricing power in the domestic mainstream market as "weak."
  • The battery technology gap is being narrowed by competitors. Blade Battery was once a clear lead, but competitors can use different paths — ternary, other LFP/sodium battery solutions — to deliver similar consumer value. BYD's excess profit can then be eroded. The report's point is that the moat is more like "scale and cost structure that are hard to catch," not "others simply cannot replace it."
  • Price wars erode profitability. This is the hardest evidence: 2025 gross margin fell from 19.44% to 17.74%, net profit attributable to shareholders fell -19%, and 2026Q1 revenue fell -11.82% while net profit attributable to shareholders fell -55.38%. Sales and industry position rose, but profit and cash flow retreated. The "width" of the moat did not automatically translate into shareholder returns.

  Final net judgment. The moat remains real and hard to copy; neither I nor the report doubts this (moat strength 4/5). But remember its nature: it is a cost-leadership moat, not an irreplaceability moat. The difference matters. Cost leadership requires continuous large capex to maintain; it does not collect money while resting. The most direct reminder from 2025 is that operating cash flow was RMB 59.1 billion while capex reached RMB 156.8 billion, free cash flow turned negative to -RMB 97.7 billion, and total borrowings jumped from RMB 28.6 billion to RMB 113.4 billion. In other words, this moat must keep being fed with cash to stay wide. The wider the moat, the more capex it may need. Over the next three to five years, if high-margin increments from overseas and premiumization outrun domestic price-war bleeding, the moat widens on net; otherwise it narrows on net. This is precisely why the report gives "Watch," not an aggressive Buy.

• QIf its core business is disrupted, does it have the DNA to reinvent itself? How does it handle mistakes and bad news?6/10

  A

  Conclusion first: the DNA for reinvention is very strong; handling mistakes and bad news is a relative weakness and deserves a discount. These two must be separated. BYD has used thirty years to prove it can repeatedly rebuild itself with engineering strength, but its external communication about its own problems is indeed tilted toward positive messaging. The report also notes this when giving "management and capital allocation" 3.5/5, saying disclosures are "still clearly promotional in wording, and discussion of competition, capital returns, and high-investment low-return risks is not sufficient."

  Start with the strength: the reinvention DNA is real and repeatedly proven by history. BYD is not a company living off one legacy business. Its main business has been disrupted by itself more than once: it began in 1995 as a handset battery OEM, then acquired Xi'an Qinchuan Automobile for RMB 270 million in 2003 and crossed into cars. That step was deeply unpopular at the time; the share price fell about 20% on the day the news came out, but Wang Chuanfu insisted on devoting the rest of his life to NEVs. Its ability to rebuild from lows is even more telling: in 2019, net profit fell about 42% YoY to only RMB 1.6 billion, a typical ugly moment of stalled growth and bottoming profit; then in 2021, it turned around through DM-i Super Hybrid, with plug-in hybrid sales rising from about 48,000 units in 2020 to about 1.43 million units in 2023, nearly 30x growth; in March 2022, it became the world's first automaker to officially stop producing fuel vehicles, voluntarily cutting off its legacy base and betting everything on electrification. This series of pivots — battery → fuel cars → DM hybrid → BEV → Blade Battery → premiumization and globalization — rests on the hard foundation repeatedly emphasized by the report: cumulative R&D investment above RMB 180 billion and more than 120,000 R&D engineers (report basis: 2025 R&D expense of RMB 57.978 billion). Wang Chuanfu's own sentence captures the culture: "Even if all our assets, including factories, patents, and shares, disappeared, as long as the engineers remain, we can rise again at any time." In other words, if the core business is disrupted one day, this company probably has the ability to reinvent itself again. That is its highest-scoring attribute.

  Now the weakness: transparency around mistakes and bad news deserves a discount. As a star manufacturer closely watched by CCTV and local governments, BYD's external communication naturally carries a promotional tone, and bad news tends to be softened or acknowledged slowly. The report already reads this in the annual report: it acknowledges that the company did disclose adverse information such as gross margin decline, lower operating cash flow, and higher total borrowings, but also states that the wording is promotional and discussion of capital returns and high-investment low-return risks is insufficient. One external corroboration is the supplier payment-cycle controversy. The long-criticized issue of using supplier funds was not corrected after proactive self-reflection, but only moved when regulators pushed and the industry came under collective pressure. In 2024, BYD's payment cycle to upstream suppliers was about 127 days; only after the Regulation on Ensuring Payment to Small and Medium-Sized Enterprises took effect in June 2025 and more than ten automakers collectively made statements did BYD announce a unified payment period within 60 days. Later research showed that implementation of industry commitments was discounted, and more than 60% of suppliers had not signed clear new "60-day" contracts. Similarly, pressures from price wars, overseas setbacks, and dealer financing problems — such as a 2025 funding-chain break at a major Shandong dealer affecting thousands of car owners, when BYD first said it was "unrelated to company operations" before later helping resolve it — tend to be "managed" rather than candidly placed on the table.

  Net judgment: score "reinvention ability" and "transparent handling of mistakes" separately. The former is BYD's genuine hidden asset: it has strong tolerance and recovery ability when disruptive change arrives. The latter is a relative weakness. Investors should not expect it to proactively, promptly, and fully explain bad news; they need to track the hard indicators listed in the report — gross margin, operating cash flow and free cash flow, inventory days, overseas margins, and refinancing actions — to cross-check management's public narrative. This also matches the report's "Watch" rating and 3.5/5 management score: business and team resilience are trustworthy, but shareholder-friendliness and candor are not high enough for full marks.

• QDoes management, especially the founder, have a long-term view and deep alignment with the company? Is it willing to sacrifice current profit for five to ten years from now?7/10

  A

  Conclusion first: on the metric Baillie Gifford cares about most, BYD fits quite well, but not perfectly. The founding team are real major shareholders, the long-term view is clear, and management is indeed willing to sacrifice current profit for the company's position five to ten years from now. The only discount is that this long-termism is applied more to "making the company bigger" than to "making per-share value thicker." Baillie Gifford asks whether management is willing to sacrifice near-term profit for the long term; BYD is almost a textbook "yes." But Baillie Gifford also cares whether shareholders receive the results, and on that point BYD is merely adequate.

  1. Alignment: the founding team are major shareholders, not option-paid professional managers. Wang Chuanfu is both chairman and president, an engineer by background, and personally drives technical direction. He holds about 16.90%; early co-founders Lu Xiangyang and Xia Zuoquan hold about 12.98% and 2.72% respectively. The founding team has a very high combined stake, and their wealth is heavily tied to this company. This structure naturally pushes management decisions toward the long term: they are not working for next quarter's bonus, but for what their large equity stake is worth ten years from now. The report's judgment is that "the founder is deeply bound, and interests are not detached from shareholders." I agree.

  2. Long-term view: willingness to sacrifice current profit for five to ten years from now has hard evidence. This is BYD's most "Baillie Gifford" side. In 2025, R&D expense was RMB 57.978 billion, engineers exceeded 120,000, and cumulative R&D investment exceeded RMB 180 billion. This is classic "spend today, harvest ten years later." Cash flow is even more direct evidence: 2025 operating cash flow was RMB 59.1 billion, while capex reached RMB 156.8 billion, so free cash flow turned negative at -RMB 97.7 billion, and total borrowings jumped from RMB 28.6 billion to RMB 113.4 billion. A company that voluntarily lets free cash flow turn negative and adds leverage to build capacity, go overseas, and fill technology gaps is, in substance, sacrificing current profit for market position five to ten years out. Gross margin fell from 19.44% to 17.74% and net profit attributable to shareholders fell about -19% in the same period, yet management did not shrink to protect short-term margins; it kept giving profit to scale and share (2025 overseas sales 1.046 million units, +150.7%, exports above 1 million). This founder trait was identified early: after Berkshire invested in BYD in 2008, Munger described Wang Chuanfu as "a combination of Edison and Welch — like Edison in solving technical problems, and like Welch in getting things done", valuing precisely this engineer temperament + strong execution as a long-term builder.

  3. Honest discount: the long-termism leans toward "making the enterprise bigger," not "making each share more valuable." This tension must be stated clearly. In 2024–2025, BYD paid a large dividend (2024 profit distribution including about RMB 12.077 billion in cash dividends) plus a high bonus/share conversion (8 bonus shares and 12 converted shares for every 10 shares), then placed 129.8 million new H shares for net proceeds of about HK$43.383 billion. Paying cash out with one hand while diluting with the other is not clean on a per-share basis. The report worries that management is overemphasizing global share and industrial position while weakening discipline around per-share shareholder returns, and notes that buybacks are small relative to market cap and mostly related to employee share arrangements, not typical large cancellation-style repurchases when undervalued. The report ultimately gives "management and capital allocation" 3.5/5: long-term orientation is clear and there is no fraudulent aggressiveness, but discipline around per-share shareholder returns is average.

  How to interpret this for investment: the Baillie Gifford question is whether the founder is a long-term builder willing to bet for the future. BYD answers well. Wang Chuanfu, as an engineer-founder with heavy R&D and capacity investment, is exactly the type of person LTGG seeks. But readers must distinguish management's long-term view (strong) from how much of those long-term results accrue to each share (average). In other words, BYD's management is trustworthy and willing to sacrifice today for ten years out, but its priority is to build BYD into a global industrial platform, not to return excess cash quickly through dividends/buybacks and protect each share from dilution. For growth-oriented long-term investors, this is positive; for conservative investors focused on the rhythm of shareholder returns and unwilling to be diluted, it is a discount. This matches the report's overall conclusion: company quality passes, but the current price has a thin margin of safety and the rating is Watch.

• QIf it disappeared tomorrow, how much would customers miss it? Is its growth model sustainable and not dependent on harming society or regulation?4/10

  A

  Conclusion first: if BYD disappeared tomorrow, consumers would regret it, but they would not be "heartbroken." It has given the mass market a highly cost-effective NEV choice, but if it disappeared, Geely, Tesla, new EV makers, and joint-venture brands would quickly fill the gap. Cars naturally have many substitutes and low switching costs; the report also scores BYD's "switching costs" only as medium to weak. The groups that would truly "miss it" are its suppliers and employees, and the industrial chain that treats electrification as national policy. From a social-value perspective, BYD is the kind of company Baillie Gifford would appreciate: it has genuinely pushed electrification and carbon reduction from the high end to the mass market. In 2025, it sold about 4.6 million units, exported more than 1 million vehicles for the first time, and covered 119 countries and regions. That is positive social contribution.

  But the second layer — whether its growth model is sustainable and not dependent on harming society or regulation — must be marked with an honest question mark. This is a real crack in the upside story. BYD's rapid scale expansion in recent years has been widely questioned as relying heavily on two things regulators and public opinion dislike: aggressive price wars and very long supplier payment terms/use of supplier funds.

  • The price war has already crossed into regulatory sensitivity. At the end of May 2025, BYD cut prices sharply, with some models discounted by as much as about 34%, and the cheapest Seagull falling to about USD 7,700. Great Wall Motor chairman Wei Jianjun then warned that the auto industry already had an "Evergrande-style" crisis, only not yet erupted. The state-backed China Association of Automobile Manufacturers also urged automakers not to "dump below cost," which foreign media interpreted as an implicit reference to BYD. This is the "anti-involution" campaign regulators have pushed since 2025 to restrain meaningless internal competition. By early 2026, Beijing was still warning automakers as the price war escalated, showing this crack had not closed.

  • The long payment-cycle issue more directly points to "using upstream funds to finance expansion." According to Bloomberg estimates, BYD took about 275 days on average in 2023 to pay suppliers (BYD says 127 days), using an internal digital payable certificate called "DiLink." Suppliers either wait or discount the certificates to receive cash early. This is the other side of the same financial fact in the report: BYD has long supported expansion through a very strong payables system and working-capital management. At the end of 2025, net current liabilities were still about RMB 96.984 billion, and the reduction in operating payables was one important reason cash flow worsened and free cash flow turned negative at -RMB 97.7 billion. In other words, part of past high-speed growth shifted funding pressure onto upstream small and medium suppliers.

  Regulators have begun closing both routes, which raises the difficulty of BYD's growth. The Regulation on Ensuring Payment to Small and Medium-Sized Enterprises, effective June 1, 2025, requires large companies in principle to pay within 60 days and bans disguised delays through commercial bills. On June 10–11, 17 automakers including BYD collectively pledged to shorten supplier payment cycles to within 60 days. By December 2025, BYD began dismantling the DiLink system, which had issued more than RMB 400 billion cumulatively, and transitioning over 2–3 years to cash and standardized bills under central bank rules. According to Caixin in February 2026, average payment cycles at major automakers had fallen from about 64 days to 54 days, though implementation was still criticized as "good-looking data, poor real-world feeling," and pain for small suppliers may not be fully resolved.

  Net judgment: BYD's social value is positive: it is indeed promoting carbon reduction and mass-market electrification. But its past growth model of "price wars + using upstream funds" is exactly what regulators' "anti-involution" campaign and new payment-cycle rules since 2025 are trying to correct. This means BYD can no longer use these two levers to amplify scale at no cost. Paying suppliers faster consumes cash and reduces working-capital flexibility, while constrained price wars limit its ability to keep taking share through low prices. This fully matches the report's core contradiction — "scale keeps expanding, but shareholder returns are under pressure" — and its judgment that domestic mass-market pricing power is narrowing. For bulls, this is not a fatal flaw, but it reminds you that one foundation of BYD's growth story is being repriced by regulation, and sustainability deserves a real discount.

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

  A

  Conclusion first: the unit economics are ordinary and recently under pressure. This is a typical thin-margin auto manufacturing business, not the light-asset compounding machine Baillie Gifford prefers, where unit economics improve as scale grows. More painfully, right now "larger scale is making it less profitable": in theory, vertical integration should create positive scale effects, but price wars have swallowed those scale benefits, turning it into "selling more but earning thinner margins." The money earned is also barely left for shareholders; it is almost all reinvested in R&D and capacity expansion.

  Unit economics: thin and moving downward. In 2025, group gross margin was 17.74%, down from 19.44% in 2024; net margin was only 4.1%, and net profit attributable to shareholders was RMB 32.619 billion, down about -19% YoY. In 2026Q1, net profit attributable to shareholders fell another 55.38% YoY. In other words, for every RMB 100 of cars sold, only a little over RMB 4 remains after tax, and that figure is shrinking. This is why the report describes BYD as an "excellent company in a difficult industry," not a "light-asset king in a good industry." Automobiles are inherently capital-intensive, cyclical, and unstable in profit, and BYD cannot change the physics of the industry however strong it is. One honest detail: the 2026Q1 profit halving was significantly affected by non-operating drag, including about RMB 1.2 billion in FX losses and asset impairments, while single-quarter gross margin actually recovered sequentially to 18.81%, a near one-year high. So the "gross margin floor" is not as bad as the net profit line looks, but the thin-margin nature remains.

  Does scale make unit economics better or worse? The current truth is "worse." In theory, BYD's vertical integration — self-developed and self-produced Blade Batteries, motors, and electronic controls — plus 4.6 million units of scale should spread R&D, manufacturing, and procurement costs and create positive scale effects. The report also confirms that the cost and scale moats are real and widening. But in reality, all competitors in China's domestic mass market are cutting prices, pricing power is narrowing, and price cuts are outrunning cost reduction. The result is counterintuitive: sales and industry position rise, while margins and cash flow fall. The report's 2021–2025 table shows the turning point clearly: 2021–2024 was the sweet period of "revenue, profit, and cash flow rising together" (gross margin rising from 12.5% to 19.4%); starting in 2025, it became "share keeps expanding, returns start shrinking." The scale dividend has not disappeared, but it is currently being eaten by price wars.

  Where did the money go? Mostly not to shareholders, but back into the business. Three destinations: first, R&D, with 2025 R&D expense of RMB 57.978 billion (about RMB 63.4 billion of total annual R&D investment if capitalized items are included) and more than 120,000 engineers; second, capex, with cash outflow for purchasing and constructing fixed assets and similar items as high as RMB 156.808 billion (capacity expansion, overseas factories, technology), and net investing cash outflow of about RMB 127.6 billion that year; third, dividends, with 2024 profit distribution including about RMB 12.077 billion in cash dividends plus high bonus/share conversion. The direct cost of this spending pattern is that although 2025 operating cash flow was RMB 59.136 billion, it could not cover huge capex; free cash flow turned negative at -RMB 97.7 billion, and total borrowings jumped from RMB 28.584 billion in 2024 to RMB 113.435 billion, moving from net cash to net debt. Under the report's owner-earnings framework, the cash truly freely available to shareholders in 2025 was only about RMB 0–9 billion. This is where BYD least resembles a Buffett-style business.

  One-sentence wrap-up: this is not a compounding machine where "the larger the scale, the better the unit economics, and cash gushes back to shareholders." It is an asset-heavy business with pressured incremental returns that must keep investing heavily to maintain leadership. Short-term leverage remains manageable (interest coverage about 15.7x, net debt/EBITDA roughly 0.4x), but the report identifies "whether free cash flow can be recovered with expansion" as the most fragile assumption in the entire valuation. That is also the key indicator for whether the unit economics of this business can improve again.

• QWhat conditions must all hold for it to rise 5x in ten years? Are those conditions realistic? What expectations are embedded in today's share price?3/10

  A

  Conclusion first: a ten-year 5x path is not impossible, but it requires several links of "industry fundamentals keep exceeding expectations + valuation does not compress" to all go right. It is not a case of buying cheaply today and waiting for valuation repair. The current H-share price is about HK$91.75 (basically in line with the report base of HK$90.2 on 2026-05-20), and market cap is about HK$830 billion (about USD 107 billion). A 5x in ten years means market cap must reach about HK$4.15 trillion (about USD 540 billion). For context, that is more than twice Toyota's current market value (about USD 246 billion) and about one-third of Tesla's current market value (about USD 1.59 trillion). In other words, a 5x BYD would have to sit firmly among the world's highest-value automakers, which shows how high the bar is.

  For this to happen, the following conditions must more or less all materialize:

  • ① Global share rises sharply and overseas markets truly make money. In 2025, overseas sales were 1.046 million units (+150.7%), and finished-vehicle exports exceeded 1 million units. The company also points to a 2026 target around 1.5 million units. A ten-year 5x requires overseas to grow from "million-unit scale" to "multi-million-unit scale," and crucially overseas margins must be higher than domestic margins, turning share into profit rather than being consumed by tariffs, local factories, and channel investment.
  • ② Margins recover significantly from price wars. In 2025, gross margin had slipped from 19.44% to 17.74%, net profit attributable to shareholders fell -19%, net margin fell to about 4.1%, and 2026Q1 net profit attributable to shareholders fell -55.38% YoY. To support 5x, net margin must recover from suppressed lows and stabilize, rather than continuing a pattern of "more sales, thinner profit."
  • ③ Premiumization / energy storage / intelligence second curves become meaningful profits. In the report, high-end brands such as Denza, Yangwang, and Fangchengbao are still in the build-out stage (the upgraded Denza N9 starting price rose only about 5%) and remain far from "consumers recognizing only the brand and ignoring price." These second curves must truly contribute profit and raise product mix, not only provide narrative.
  • ④ Valuation multiples do not compress sharply. This is easy to overlook. The report's 2025 PE is about 21.9x and P/B about 2.9x, already a significant premium to cheaper peers such as Geely (PE about 10.7x–11.8x). If the market one day prices BYD as a "mature Chinese automaker" rather than a "global growth leader," PE/PB compression could offset profit growth, making 5x much harder.

  Are these conditions realistic? Each individual condition is not absurd. BYD's scale, cost structure, vertical integration, and R&D (2025 R&D expense RMB 57.978 billion, more than 120,000 engineers) are real capabilities. But "five conditions all holding, and continuously for ten years" is a demanding joint probability. If any link fails — overseas does not earn money, gross margin stays below 15% for long, second curves do not take off, or valuation falls back to mature-auto levels — the 5x outcome fails. The report's own neutral case is about 8%–12% annualized return over ten years, while the optimistic case is 14%–18%; achieving 5x (about 17% annualized) basically requires its optimistic case or more.

  What expectations are embedded in today's share price? HK$91.75 corresponds to the upper side of reasonable relative to the report's HK$100–125 reasonable range. The report calls it "toward the upper end of reasonable, not cheap enough," with an ideal buy price of HK$60–75 and a required margin of safety of 25%–30%. In other words, today's market price has already prepaid a lot of the expectation that "the winner keeps winning", and the margin of safety is not thick. This means a 5x rise would have to be earned almost entirely through "fundamentals continuing to exceed expectations," not "undervaluation repair." Today you are not buying a discounted asset (the report calculates common shareholders' book value per share at only about RMB 25, far below current price). Also remember: Tesla is more expensive and includes a large amount of autonomous driving / robotics option value; using a more expensive peer to argue BYD is cheap does not work. The report also warns that if the narrative reverses and valuation returns to 1.5x–2.0x common shareholders' equity or depressed earnings multiples, the share price could fall to HK$40–55, implying about 40%–55% permanent capital loss risk. That is the other side of the 5x story.

  Final sentence: a ten-year 5x script can be written, but it requires BYD to become one of the world's largest automakers by market value and for multiple links to exceed expectations continuously. Today's starting valuation is not cheap and the margin of safety is thin, so this path depends more on luck and sustained execution than on certainty.

• QWhy has the market not realized all this? Is it because it does not understand, looks down on it, or does not look far enough? What will become the "narrative inflection point"?3/10

  A

  Start with the premise: BYD is not a "buried" stock. The hidden premise of Baillie Gifford's tenth question is to find odds created by market misjudgment. For BYD, that premise mostly does not hold. It has ranked first globally in NEV sales for four consecutive years, and sell-side coverage is very dense (about 28 institutions track it, with a 12-month average target price of about HK$124.52; the report base H-share price was HK$90.2, and the current price is about HK$91.75). A stock repeatedly dissected by so many analysts, with an average target price about one-third above the current price, is not "misunderstood," and even less "looked down upon." The market has realized BYD is strong. The disagreement is what price is reasonable for that strength.

  The real tug of war is therefore not "understood/looked down upon," but "too near-term" versus "not long-term enough."

  • The too-near-term side (bearish/neutral) focuses on current financials: 2025 gross margin fell from 19.44% to 17.74%, net profit attributable to shareholders fell about -19% YoY, free cash flow turned negative at -RMB 97.7 billion, and total borrowings jumped from RMB 28.6 billion to RMB 113.435 billion. In 2026Q1, revenue fell -11.82% YoY and net profit attributable to shareholders fell -55.38%. To them, this is the price-war outcome of "more sales, but less profit per car." In 2025, ASP had fallen to about RMB 119,200, and BYD even lost the monthly sales crown to Geely in January 2026.
  • The long-term bullish side argues that the market is still pricing a company moving from a "Chinese EV story" to a "global industrial platform" as a "Chinese automaker": in 2025, overseas revenue already reached 38.65%, finished-vehicle exports exceeded 1 million units (+150.7%), vertical integration (Blade Battery + e-Platform 3.0) and cumulative R&D above RMB 180 billion form a ten-year moat, and current profit declines are only cash mismatches during expansion.

  The report sits in the middle of this tug of war with a cautious bias: company quality "passes," but the current price is "toward the upper end of reasonable, not cheap enough," so it gives Watch. The report's reasonable intrinsic value range is HK$100–125, while the ideal buy range is only HK$60–75.

  What will become the "narrative inflection point"? I would watch several verifiable triggers, both positive and negative:

  1. Overseas margins are proven — if overseas expansion is verified as "truly profitable" (overseas gross margin materially above domestic, rather than market share bought through subsidies and factory spending), the market has reason to re-rate it from "Chinese automaker" to "global platform." This is one of the report's named key assumptions.
  2. "Anti-involution" eases price wars — the Central Economic Work Conference has set the task of correcting "involution-style" competition, the State Administration for Market Regulation has solicited opinions on the Automobile Industry Price Behavior Compliance Guide, and BYD has publicly supported standardized price competition. If the price war truly shifts from "hard fighting" to "hard constraints," domestic gross-margin repair would be the most direct bull catalyst.
  3. A second curve scales — if any of premiumization (Denza/Yangwang/Fangchengbao), intelligent driving, or energy storage reaches scale and pricing power, it could rewrite the narrative that BYD "only sells cheap cars."
  4. Reverse inflection (do not only think about upside) — if overseas is blocked by tariffs/localization setbacks, price wars worsen further, or gross margin stays below 15% for a long time, the narrative moves toward the report's downside scenario: valuation reverts to 1.5–2.0x common shareholders' equity, corresponding to HK$40–55 and about 40%–55% permanent capital loss risk.

  Honest close: this is consistent with the earlier questions, whether from Serenity's value-capture lens or Buffett's margin-of-safety lens. BYD is not an "undiscovered cheap growth stock." Its strengths are already fully priced and fully debated. The real disagreement is whether this known quality is worth today's HK$91.75. The report's answer is: watch first, wait for a thicker margin of safety, and do not loosen the entry discipline simply because the company is excellent. The inflection point is not so much "the market finally understands" as the moment when the variables above are proven or disproven by the financial statements.

The must-ask before buying — finding a "good business," with the core question: "Who owns the moat?"

• QCan you explain this company's business model in one sentence?

  A

  One-sentence framing: BYD is the global leader that has ranked first in new energy vehicle sales for four consecutive years. It makes money by using vertical integration + scale to build vehicles and sell them together with its in-house core electric powertrain components such as batteries, motors, and electronic controls, while using its electronics OEM business, including handset components and assembly, as a cash-flow buffer. Put more plainly, it is an asset-heavy manufacturer that has internalized many links from batteries to finished vehicles. It mainly collects money by selling cars and core components, not by sitting back on subscriptions, paywalls, or brand premiums.

  How exactly does it make money, and what does the revenue structure look like? On the report's basis, in 2025, "automobiles, automobile-related products and other products" contributed about 80.68% of revenue, while handset components, assembly, and other products contributed about 19.31%. Today's profit engine has clearly shifted to automobiles, with electronics OEM falling back to a supplementary role and cash-flow buffer. By customer geography, mainland China, Hong Kong, Macau, and Taiwan accounted for about 61.35%, and overseas markets about 38.65%. In 2025, finished-vehicle exports exceeded 1 million units for the first time, and the business covered 119 countries and regions. It is therefore no longer only a "Chinese EV story"; it is evolving toward a global industrial platform. In terms of how it gets paid, the auto business faces dispersed end consumers, dealers, and overseas channel partners, while the electronics business is closer to a large-customer OEM model.

  The quality of this business must be understood clearly: it is a typical asset-heavy manufacturing business with high R&D, high investment, high turnover, and high execution intensity, not a light-capital business that requires little reinvestment and throws off abundant cash. In 2025, operating costs reached RMB 661.3 billion, R&D expenses were RMB 57.978 billion, and cash capital expenditure for purchases and construction of fixed assets and similar items reached RMB 156.8 billion. The more important reminder is that its revenue is not highly recurring or strongly subscription-like. It is essentially transactional revenue at the intersection of industrial manufacturing and consumer goods, and its predictability is materially weaker than that of utilities, software, condiments, or premium liquor, the traditional "honor students" of value investing. Money from selling one car does not automatically come back again next month. The report scores this business at 4/5 for "understandability": it is not mysterious, but there are many operating variables and heavy capital consumption. It is a complex industrial system that is "understandable, but not easy."

  Final one-sentence wrap-up: BYD's business model can be summarized as "using vertical integration to compress costs and scale to spread expenses, selling vehicles and self-developed electric powertrain systems to global consumers, while using electronics OEM to cushion cash flow." The business itself is clear and understandable, but it is capital-intensive heavy manufacturing. It earns money from turnover and execution, not from subscription-like stable cash flow. This is also the starting point for repeatedly weighing, in the following questions, how deep the moat is, how stable the cash flow is, and whether the price offers a margin of safety.

• QIs this market large enough? Is there still room to grow over the next 10–20 years?

  A

  Conclusion first: the industry ceiling is high enough, and there is still significant room to grow over the next 10–20 years, but the "dividend zone" of growth is shifting from China to overseas markets, and a "large market" does not automatically mean "BYD can make more money from all of it." This is precisely one of the core reasons the report assigns a "Watch" rating rather than an aggressive Buy.

  Start with how large the pie is, and how long it can still grow. The global EV penetration curve remains clearly upward. According to the IEA's Global EV Outlook 2026, global EV sales grew 20% YoY in 2025, exceeded 20 million units, and accounted for about one-quarter (25%) of new car sales; they are expected to rise to 23 million units in 2026, or about 28%. China is the world's largest single market: in 2025, EVs already accounted for nearly 55% of new car sales, while about 75% of global EV production capacity was concentrated in China, and China's EV exports doubled to a record high of more than 2.5 million units. Considering that penetration in most markets outside China and Europe is still in single digits to the 20%-30% range, the industry-level judgment that "there is still major room over the next 10–20 years" is defensible. The report also therefore gives passing marks to "long-term stable demand" and "industry attractiveness (4/5)."

  The key turning point, however, is that China's domestic market has already moved from a blue ocean to a high-penetration red ocean. A bigger pie does not mean everyone can take a bigger slice. This is something the report repeatedly stresses and that I must state honestly. China's NEV penetration is already so high that monthly retail penetration first exceeded 60% in April 2026 (reaching 61.4%) and rose further to about 63% in May; at the same time, cumulative passenger NEV retail sales in the first 5 months of 2026 actually fell about 14% YoY. In other words, penetration is still hitting new highs, but domestic volume growth has basically peaked and has even contracted in phases. What remains is a brutal price war in the existing stock market. The IEA also states plainly that intense domestic competition in China is squeezing margins and pushing manufacturers overseas in search of higher profits. Add to that China's auto industry profit margin once falling to 2.9% in early 2026, a multi-year low, and Goldman Sachs' estimate that China's EV capacity could reach about 25 million units/year by 2026, almost equal to global annual demand. "Large market" and "thin profits" are both true. This matches BYD's own data in the report: 2025 sales were about 4.6 million units and scale was still rising, yet gross margin fell from 19.44% to 17.74%, net profit attributable to shareholders fell -19% YoY, 2026Q1 revenue fell -11.82%, and net profit attributable to shareholders plunged 55.38%.

  Where, then, can BYD's growth come from? Mainly two new growth poles, but both must be proven by "making money," not only by "selling more." The first is overseas expansion. The report discloses that BYD's overseas sales reached 1.046 million units in 2025, up 150.7% YoY; finished-vehicle exports exceeded 1 million units for the first time, covering 119 countries and regions; management's 2026 overseas target points to the 1.5 million-unit level. This is consistent with the IEA's point that "Chinese manufacturers are going overseas to find profit," and overseas unit profit is usually higher than in the inwardly competitive domestic market. The second is energy businesses beyond automobiles, such as energy storage and batteries, as new growth poles. But the report also flags two risks: overseas expansion must absorb tariffs, local factory construction, and channel investment, with a long capital recovery cycle (2025 free cash flow had turned negative at -RMB 97.7 billion, and total borrowings jumped from RMB 28.6 billion to RMB 113.4 billion); and whether premiumization through Denza/Yangwang/Fangchengbao can truly establish brand pricing power is still under construction.

  Putting this into investment terms: the industry's long-term growth is not the main risk for BYD stock. The real variable is whether BYD can turn larger sales volume back into higher per-share shareholder returns. The report's reasonable intrinsic value range is HK$100–125, with an ideal buying range of HK$60–75. The current price (about HK$91.75, basically in line with the report baseline of HK$90.2) looks more like the upper side of reasonable, and the margin of safety is not thick for balanced but conservative investors. The underlying logic is exactly this: "a high industry ceiling ≠ this company can comfortably earn that money."

  Jun 4, 2026
• QIs its moat deep enough? Is it hard for competitors to copy?

  A

  Conclusion first: the moat is indeed deep and hard to catch, but it is the "cost + scale + vertical integration" type, not the "others simply cannot replace it" type. The report scores the moat at 4/5: there are solid barriers, but this is not the kind of business that can stop investing and collect rent purely on brand. In other words, competitors will find it very hard to quickly replicate BYD's scale and cost structure, but if they use another path to deliver similar consumer value, BYD's excess profits can still be ground thinner.

  Where exactly is the moat? The core is vertical integration, not network effects. BYD's hardest barrier comes from its large-scale self-development and self-production of core links such as batteries, motors, and electronic controls, then using e-Platform 3.0 to integrate the Blade Battery as a structural part of the vehicle platform. Third-party data supports this: BYD manufactures about 75% of finished-vehicle components internally, from Blade Batteries and power semiconductors to motors and even its own transport fleet. Wang Chuanfu himself has described "batteries accounting for as much as 40% of vehicle cost, and BYD controlling this part itself" as BYD's core competitiveness. The direct benefit is removing layers of external supplier markups and maintaining, even increasing, production during chip shortages. Add scale: 2025 sales of about 4.6 million units, exports above 1 million units, coverage across 119 countries and regions, 2025 R&D expense of RMB 57.978 billion, cumulative R&D investment above RMB 180 billion, and more than 120,000 R&D engineers. Costs in R&D, manufacturing, procurement, and channels can all be spread faster. This is what the report means by "cost advantage: strong" and "scale advantage: strong."

  Looking item by item through the report's ten moat categories, strength is very uneven:

  • Cost advantage: strong; scale advantage: strong; corporate culture/operating execution: strong — these three are BYD's real barriers.
  • Brand advantage: moderately strong — it is already a strong mass-market brand, but luxury pricing power is still under construction. BYD is moving upward with Denza and Yangwang. The new Denza N9 starting price was raised by about 5% to RMB 409,800, and overseas the Z9 GT is priced close to the Porsche Panamera range. The direction is right, but it is far from a point where "consumers recognize only the badge and ignore price."
  • Channel advantage: moderately strong, and rapidly strengthening overseas; patent/regulatory barriers: medium; data advantage: medium (not yet an independent moat); capital allocation ability: medium.
  • Network effects: weak; switching costs: medium to weak — these are precisely where software and platform-type "ideal moats" are strongest, and BYD basically does not rely on them.

  The "direction" of the moat is more worth watching than its "height": overall stable and locally widening, but not widening automatically. The cost and scale moat is widening; the premiumization and intelligence moat is still being built; while pricing power in the domestic mass-market car segment is narrowing, because every competitor is cutting prices. This is already visible in the financial statements: in 2025, gross margin slipped from 19.44% to 17.74%, net profit attributable to shareholders fell about -19% YoY, and in 2026Q1 revenue fell -11.82% YoY while net profit attributable to shareholders fell -55.38% YoY. In its checklist, the report also honestly marks "does it have pricing power" as uncertain: there is some ability overseas and in premium segments, but domestic mainstream markets are weak. A strong moat therefore does not mean shareholder returns must be strong. Part of the high profitability of the past two years came from industry expansion and export dividends; do not treat it as a permanent norm.

  Can competitors copy it? Copying BYD requires years of R&D accumulation + hundreds of billions to a trillion-level capital + supply chain coordination + management execution. That threshold is genuinely high, and no one can simply duplicate it in the short term. But the report is also honest: "very hard to catch its scale and cost structure" does not mean "others simply cannot replace it." Competitors do not have to copy the same technology platform. If they use different paths to deliver similar product strength, they can erode BYD's excess profits. This is why the report gives high marks to company quality (moat 4/5) but sets the overall rating at Watch: the barriers are real, but BYD is the "strongest executor" in a capital-intensive, brutally competitive auto manufacturing industry, not a light-asset king in a good industry that can easily collect rent.

• QWhere will its growth come from? (Industry growth / market share / pricing / capital allocation)

  A

  Conclusion first: BYD's future growth engines have only two main axes: overseas expansion + premiumization. The other two traditional levers, industry beta and domestic share, are respectively a slow tailwind and, in some ways, already a headwind. The report says this plainly: larger sales volume does not equal thicker profit. Therefore, "where growth comes from" must be split into "where sales volume comes from" and "where profit comes from." They do not move in sync. Below is a reconciliation across four dimensions.

  ① Industry growth (mild tailwind, but not the main engine): The broad direction of electrification is still progressing. The report cites the IEA: global EV sales exceeded 20 million units in 2025, about one-quarter of new car sales, and are expected to rise to 23 million units in 2026, or about 28%; China's 2025 EV penetration was already close to 55%, and is expected to approach 60% in 2026. The issue is that China has shifted from a "high-growth blue ocean" to a "high-penetration, high-competition red ocean." Industry incremental volume is coming more from rising overseas penetration than from domestic total-volume expansion. Industry beta remains, but for a company already selling 4.6 million units, its marginal contribution is limited.

  ② Market share (overseas is the largest increment, while domestic share is actually shrinking): This is the most important and easiest item to misread. Overseas is the real source of incremental growth: in 2025, BYD overseas sales were about 1.046 million units, up +150.7% YoY; finished-vehicle exports exceeded 1 million units for the first time and covered 119 countries and regions. Management is placing a heavy bet here — at the end of March, the 2026 overseas target was raised from the early-year 1.3 million units to 1.5 million units, more than 40% above 2025, and management has said overseas could eventually account for about half the business. But domestic share is not "flatlining on a high base"; it is actively giving ground: according to CNBC, BYD's share of China's EV market has slipped from about 27% a year earlier to about 17% in early 2026, with passenger vehicle sales declining YoY for several consecutive months. Geely, Leapmotor, and others are taking share from its mid-market heartland. In other words, today BYD's "market-share growth" is almost entirely contributed by overseas markets, while the domestic leg is losing blood. This is exactly why it must rely on overseas expansion as the other side of the business brightening when the home side darkens.

  ③ Pricing (two faces by market, overall weak): The report's judgment is that "there is some pricing power overseas/in premiumization, but domestic mainstream markets are weak." After checking, I think this is very accurate, and reality is even more extreme than the report describes. The premium line does have pricing power: the report mentions that the upgraded Denza N9 starting price rose by about 5%; Denza entered Europe in 2026Q1, with Z9 GT / D9 starting prices targeting about EUR 75,000, directly benchmarking BBA, while Yangwang targets Bentley and Porsche. That is a genuine move upward. But the domestic mainstream market is not merely "weak"; it is in a brutal price war: according to Automotive World, BYD's average discount in March 2026 rose to a record about 10%, and in May it cut prices on 22 models by as much as 34%. Pricing is therefore a net drag for the group overall. The structural price increases from premium segments are far from enough to offset mass-market price-for-volume behavior. This is the direct reason gross margin fell from 19.44% in 2025 to 17.74%, and 2026Q1 net profit fell -55.38% YoY.

  ④ Capital allocation (high capex for capacity and overseas factories, at the cost of negative free cash flow): BYD has chosen to reinvest cash to seize global capacity and position rather than prioritize returning cash to shareholders. In 2025, capex on a cash basis reached RMB 156.808 billion, while operating cash flow was only RMB 59.136 billion, so free cash flow turned negative at -RMB 97.7 billion. Total borrowings jumped from RMB 28.584 billion in 2024 to RMB 113.435 billion, moving from net cash to net debt. The report characterizes this style as "a capital allocator oriented toward industrial share and long-term position," not "one strictly centered on per-share intrinsic value." This approach makes sense during global expansion, but it means growth is "bought with capital." Local factories, tariffs, and channel investment in Europe, Latin America, and Southeast Asia will have long payback periods.

  Putting the four together: BYD's growth story is real, but the quality of growth is under test. The main axes are overseas expansion (volume increment) + premiumization (profit elasticity), with mild industry beta and even retreating domestic share. Supporting all of this is heavy capital intensity and negative free cash flow. The report's core reminder deserves repeated attention: it can continue selling more cars, but it may not necessarily leave more money for shareholders. The report's most important validation point lands exactly here: as overseas sales rise, are overseas margins actually higher than domestic margins? If "larger sales but thinner profits" becomes normal, then the valuation premium supported by today's growth narrative will look high. The report's reasonable value range is HK$100–125, ideal buy range is HK$60–75, and rating is "Watch."

• QIs management reliable? Is it honest and rational?

  A

  Conclusion first: management is broadly reliable, clearly long-term oriented, and deeply aligned with shareholders, but within "honest and rational," only "honest" is close to full marks; for "rational," its discipline around per-share shareholder returns deserves only a passing grade. The report gives "management and capital allocation" a score of 3.5/5, and I agree with that scale. It does not mean "untrustworthy"; it means "trustworthy in building the industry, but not yet proven to put per-share shareholder returns on the same level as global share."

  First, why "reliable + long-term oriented." Wang Chuanfu is both chairman and president. As of the end of 2025, he held about 16.90% of total share capital (directly holding about 1.541 billion A shares + 3 million H shares, excluding additional holdings through his asset management plan), while Lu Xiangyang held about 12.98% and Xia Zuoquan about 2.72%. The founding team holds a very high combined stake. This structure means the major shareholders' wealth is tied to the company, and their interests are not detached from outside shareholders. It also explains why BYD dares to keep spending heavily on R&D during the industry's most intense competition (2025 R&D expense of RMB 57.978 billion, cumulative R&D investment above RMB 180 billion, and more than 120,000 R&D engineers): this is classic "spending today's money for the position ten years from now," and is positive evidence of long-term orientation. A useful external reference: Charlie Munger pushed Berkshire to invest in BYD in 2008 precisely because he valued Wang Chuanfu himself, and in 2009 described Wang as a combination of "Edison and Jack Welch." Munger repeatedly called BYD the best investment he had made at Berkshire. That original investment of about 225 million shares for USD 230 million to acquire about 10% was a weighty endorsement from top-tier investors of this management team's execution.

  But one point must be stated honestly so readers do not misread the "Buffett halo": Berkshire is no longer a BYD shareholder. Berkshire began reducing its holding in August 2022 (after the share price had risen about 20x from cost), had reduced it below 5% by mid-2024 (below the Hong Kong disclosure threshold), and fully exited before 2025Q3, with the holding at zero by the end of June. To be fair, this looks more like valuation realization and portfolio rebalancing after a 17-year gain of more than 40x and profit of about USD 10 billion, not a vote against management integrity. The right reading is this: the original entry was a strong endorsement of management; the later exit was a judgment on price/value. Do not conflate the two. That aligns with the report's Watch rating: the company is strong, but the current price is not cheap enough.

  Now, why I do not give "rationality" full marks, and where the deduction comes from. I am not worried that BYD is aggressively fabricating results. Cash flow and profits are broadly compatible, and the report does not find signs of aggressive revenue recognition. My concern is ordinary discipline around per-share shareholder returns. The clearest evidence is the contradictory capital actions in 2024–2025: on one hand, a large cash dividend of about RMB 12.077 billion in 2024 plus a high bonus/share conversion plan (8 bonus shares and 12 converted shares for every 10 shares, expanding total share capital to 9.117 billion shares); on the other hand, in 2025 it placed 129.8 million new H shares, raising net proceeds of about HK$43.383 billion, while maintaining RMB 156.8 billion of capex. The result was operating cash flow falling from RMB 133.5 billion in 2024 to RMB 59.1 billion, free cash flow turning negative at about -RMB 97.7 billion, and total borrowings jumping from RMB 28.584 billion to RMB 113.435 billion, moving from net cash to net debt. A company truly organized around per-share intrinsic value usually would not distribute heavily and expand the share count while also asking the market for money and raising leverage. Its buybacks are also mostly related to employee shareholding or treasury arrangements, not large cancellation-style buybacks when the share price is undervalued. So the report's characterization — "a capital allocator oriented toward industrial share and long-term position, not strictly around per-share return cadence" — is accurate.

  On integrity, the balanced view is also needed: the annual report did actively disclose adverse information such as gross margin decline (19.44%→17.74%), lower operating cash flow, and higher total borrowings; it did not hide them. But the narrative remains promotional in tone, and it does not discuss competitive intensity, pressure on capital returns, or the risk of "growing larger while needing more cash" sufficiently. One-sentence conclusion: this is a trustworthy management team whose fate is tied to the company, but buyers should understand that their current first priority is global share and industrial position, while "per-share shareholder return" comes later. This is one of the core reasons the report gives 3.5/5 and an overall "Watch" rating. Against the report's discipline of an ideal buy range of HK$60–75 and a 25%–30% margin of safety, this flaw in return discipline is easier to absorb at a low enough price; when the price is not cheap enough, it becomes a risk to monitor closely.

• QWill it be stronger 10 years from now? (Will users, profits, and brand strengthen?)

  A

  Conclusion first: this is a branching question, not one with a single answer. Ten years from now, BYD will probably be larger and have stronger product capabilities than today, but "users, profits, and brand all strengthening together" is not the default outcome. It depends on whether two things are realized: whether overseas expansion/premiumization can turn scale into higher margins, and whether huge capex can gradually normalize so shareholder free cash flow turns positive. The report's rating is Watch, precisely because the company is strong, but the path to "stronger" does not happen automatically. Below are the two paths and their conditions.

  Upside path: from a "Chinese EV story" to a global industrial platform, with all three strengthening together. The report has already seen signs: in 2025, overseas sales were 1.046 million units (+150.7%), finished-vehicle exports exceeded 1 million units for the first time, coverage reached 119 countries and regions, overseas revenue contributed 38.65%, and the company clearly was no longer only a "Chinese EV story." Looking ahead, this line is still accelerating in 2026: BYD raised its full-year export target to 1.5 million units (about 15% above the January guidance of 1.3 million), sold 456,000 units overseas in January–April (nearly +60% YoY), and overseas sales reached 160,600 units in May alone, +80% YoY and more than 40% of total volume. At the same time, it is using localized manufacturing to offset tariffs: trial production at the Szeged plant in Hungary in 2026Q1 and full production before the end of Q2, plus Manisa in Turkey, Camaçari in Brazil, and Subang in Indonesia (mass production around 2026Q3). If this path works — overseas returns are truly higher than domestic returns, Denza/Yangwang/Fangchengbao make premiumization real, and R&D (RMB 57.978 billion in 2025, cumulative above RMB 180 billion, 120,000+ engineers) continues turning into product differentiation — then users (global and moving upward), brand (from "value for money" to premium), and profits (structural improvement repairing margins) will strengthen together, and BYD will confirm itself as an "excellent company in a difficult industry" while widening the gap further.

  Downside path: sales volume keeps getting larger, but not much more money is left for shareholders, and it becomes an "ordinary automaker." This is exactly what the report is most alert to, and the core reason it gives "Watch" rather than "Buy." In 2025, scale continued to rise, but gross margin fell from 19.44% to 17.74%, net profit attributable to shareholders fell -19%, free cash flow turned negative at -RMB 97.7 billion, and total borrowings jumped from RMB 28.6 billion to RMB 113.4 billion (from net cash to net debt). In 2026Q1, revenue fell -11.82% and net profit attributable to shareholders fell -55.38%. The report lays out the risks clearly: domestic price wars may turn scale advantage into "larger volume but thinner profits"; overseas growth may be swallowed by tariffs, local factories, and channel investment, with a long payback cycle; premium brands may not establish real pricing power; and capex may keep consuming cash, even requiring repeated equity financing to support expansion. If this is the path, BYD will ultimately become an ordinary auto group with large global sales, decent technology, but average capital returns. The market would stop giving it a growth premium and price it as a "mature Chinese automaker" (1.5–2.0x common shareholders' equity or 10–12x depressed earnings). The report estimates the share price could fall to HK$40–55, implying about 40%–55% permanent capital loss risk for today's buyers.

  How to judge which path is unfolding? Watch the validation signals in the report: overseas revenue mix and overseas profitability (sales must rise with profits), group and auto-business gross margins (do not let them stay below 15% for long), whether operating cash flow and free cash flow turn positive, whether capex gradually normalizes, whether it still relies frequently on equity financing, and the high-margin contribution from Denza/Yangwang/Fangchengbao. In one sentence: getting "larger" is almost certain; getting "stronger" (more profitable, with more brand pricing power) is conditional. This is why the report emphasizes that the key is not discovering that BYD is strong, but buying with a thicker margin of safety "when it remains strong yet the market is more disappointed in the short term."

• QIs the current price reasonable? Is there a margin of safety?

  A

  Conclusion first: the current price is not cheap; it is "toward the upper end of reasonable," and the margin of safety is not thick. As of 2026-06-04, the H share price was about HK$91.75, almost unchanged from the report's base date (2026-05-20) price of HK$90.2, so the valuation judgment from half a month earlier still holds. Against the report's three-scenario DCF: conservative intrinsic value HK$70–85, reasonable HK$100–125, and optimistic HK$150–190. That means the current price is expensive versus the conservative value and close to fair to slightly undervalued versus the reasonable value. It sits in the "acceptable holding range (HK$75–110)," but clearly above the report's "ideal buying range HK$60–75." The report requires at least a 25%–30% margin of safety for capital-intensive industrial stocks, and today's discount to the reasonable value midpoint is nowhere near that thick. This is why the rating stays at Watch rather than Buy.

  Why all three valuation lenses lead me to "not bad, but not cheap enough":

  • Absolute valuation (DCF): the current HK$91.75 sits between the upper end of the conservative range and the lower end of the reasonable range. The report itself is plain: the large spread between the three ranges is not because the model is fancy, but because BYD's valuation depends heavily on "whether cash can be recovered after expansion." It is not a stock easily priced on current stable free cash flow (2025 free cash flow was about -RMB 97.7 billion). Buying today means paying partly for the expectation that "the leader keeps winning and cash recovery improves," not picking up a discounted asset.
  • Relative valuation: the current price implies about 21.9x 2025 PE and about 2.9x P/B; cheaper peer Geely trades at only about 11x PE and has positive free cash flow. BYD's premium to Geely is close to "double the PE," and that only holds if overseas and premiumization materially lift margins and cash recovery. One reminder: you cannot use a more expensive Tesla to prove BYD is cheap. Tesla's valuation includes a large amount of autonomous driving/robotics option value, and using a "very expensive peer" as the reference is not a valid proof.
  • Asset value: BYD is not an asset-discount stock. In 2025, common shareholders' book value per share was about RMB 25, while the RMB-equivalent current price is far above that. In other words, you are not buying "cheap assets," but "industrial position that can still compound in the future." If growth and returns disappoint, the downside toward book value is not small.

  The most important fragile point to watch: whether normalized owner earnings can be realized. The report's reasonable range (HK$100–125) is built on the assumption of "normalized owner earnings of about RMB 50–60 billion," and the report itself admits this is the most subjective and fragile part of the entire valuation. BYD is still building global capacity, pushing premiumization, and investing in intelligence, so it is hard to cleanly separate maintenance capex from growth capex. If operating cash flow cannot return above RMB 100 billion over the next two or three years, and capex remains high (2026Q1 net profit attributable to shareholders already fell -55.38% YoY), this valuation foundation will loosen, and reasonable value will move toward the conservative value or even book value. The report's quantified extreme case is this: if the market prices it as a "mature Chinese automaker" rather than a "growth leader" (falling to about 1.5–2.0x common shareholders' equity or depressed earnings multiples), the share price could retreat to HK$40–55, implying about 40%–55% permanent capital loss risk for today's buyers. This is why "the margin of safety is not thick" matters especially for conservative investors.

  Practical conclusion: I give company quality high marks and price a neutral-to-cautious mark. Today's HK$91.75 is suitable for growth/value hybrid investors willing to track it for the long term and bear auto-industry cycles as a reasonable holding or base position. But if you follow the report's discipline and require a 25%–30% margin of safety, the steadier approach is to wait for the ideal buying range of HK$60–75 rather than relaxing the entry threshold just because the company is excellent.

Finding the "value-capture point" — the core question: "Which link will the biggest future profits bottleneck at?"

• QWhere does this company sit in the value chain?

  A

  Conclusion first: BYD is not just one link in the NEV value chain; it is a "vertically integrated automaker" spanning almost the entire chain. If the NEV value chain is drawn as upstream battery materials/lithium mines → power batteries → electric powertrain systems (motor/electronic control/power semiconductors) → finished-vehicle manufacturing → channels and overseas expansion → after-sales/energy storage, most companies occupy only one segment, such as CATL in batteries, Bosch in components, or 4S groups in channels. BYD's distinctiveness is that it has internalized several of the most critical middle links. This is why the report lists "cost, scale, and industrial synergy under vertical integration" as its strongest moat.

  Where exactly does it sit?

  • Power batteries: it self-develops and self-produces Blade Batteries, and uses e-Platform 3.0 to integrate the battery directly into the body as a structural component rather than buying cells externally. This is the essential difference between BYD and many automakers that "buy batteries and assemble cars."
  • Electric powertrain systems: it self-develops and self-produces motors and electronic controls, and e-Platform 3.0 uses an 8-in-1 integrated power system. The report cites Autoliv's annual report, describing BYD as a "highly vertically integrated" automaker with a large proportion of systems and products sourced and produced internally.
  • Power semiconductors (IGBT/SiC): the report does not expand much on this, but it is one of BYD's hardest-core vertical integration pieces. It began making automotive-grade IGBTs in 2005. Today, it can self-develop and self-produce SiC (silicon carbide) power modules and is the world's first and China's only company to mass-produce SiC three-phase full-bridge modules at scale in NEV electric drive controllers, while forming an integrated full industrial chain from chip design, wafer manufacturing, module packaging/testing to system-level application testing. In other words, it can make power devices that leave others exposed to bottlenecks.
  • Finished-vehicle manufacturing + channels/overseas expansion: this is the familiar segment. In 2025, sales were about 4.6 million units, finished-vehicle exports exceeded 1 million units for the first time, overseas sales were 1.046 million units (+150.7% YoY), operations covered 119 countries and regions, and overseas revenue already reached 38.65%.
  • Two adjacent supplements: first, handset components and assembly (BYD Electronics), contributing about 19.31% of 2025 revenue, with customers including Apple, Xiaomi, Huawei, and Samsung, gross margin around 6.29%, and expansion into AI servers/liquid cooling; second, rechargeable batteries, energy storage, and photovoltaics. The report describes electronics as a "supplement and cash-flow buffer."

  What this means for later value-capture analysis: because BYD spans multiple segments, its profit is not a toll collected from a single link. It vertically connects upstream materials cost changes, midstream battery/electric powertrain technology premiums, and downstream vehicle/channel scale effects to spread costs across the chain. This is the root of the report's "strong cost advantage and strong scale advantage." Conversely, it also means BYD is extremely capital-heavy: building battery plants, chip lines, vehicle capacity, and overseas channels at the same time is the direct reason 2025 capex reached RMB 156.8 billion and free cash flow turned negative at -RMB 97.7 billion. Full-chain coverage is both its deepest moat and the source of its cash-flow pressure. The later questions about "where profits are captured" and "whether they can turn into shareholder cash" must all start from this map of BYD standing across almost every link.

  Jun 4, 2026
• QWhat exactly does it sell? What really makes money?

  A

  One-sentence conclusion: on the surface, BYD sells finished vehicles (80.68% of 2025 revenue) plus handset components/assembly OEM (19.31%), but the money it truly earns comes from manufacturing profit squeezed out by "scaled vehicle production + full self-supply of batteries/motors/electronic controls." This is a "volume spreads cost" business, not a luxury model built on high unit premiums.

  What it sells. The report is clear: in 2025, "automobiles, automobile-related products and other products" contributed about 80.68% of revenue, while handset components, assembly, and other products contributed about 19.31%; geographically, mainland China, Hong Kong, Macau, and Taiwan accounted for about 61.35%, and overseas markets about 38.65%. On the surface, BYD is therefore a company dominated by vehicle sales, with electronics OEM as a cash-flow cushion. Customers are also dispersed: the auto side faces end consumers, dealers, and overseas channel partners, while the electronics side follows a large-customer OEM model.

  What really makes money. The key is the profit structure, not the revenue structure. BYD's profit engine is not "selling one car at a very high price," but cost advantage from vertical integration: it self-develops and self-produces Blade Batteries, e-Platform 3.0, motors, and electronic controls, then uses scale to spread R&D, manufacturing, and procurement costs, allowing it to squeeze manufacturing profit even from low-priced cars. But this profit is thin. In 2025, overall gross margin was only 17.74% (down from 19.44% in 2024), net margin was 4.1%, and net profit attributable to shareholders was RMB 32.619 billion (about -19% YoY). In other words, it earns "huge volume × a little per unit." It relies on compressing the cost structure to a level competitors struggle to copy, not on brand premium. The report's moat judgment says the same thing: the cost and scale moats are "strong but not rent-like," and pricing power in the domestic mass market is actually narrowing.

  Why this point must be stated honestly. Because the money-making engine is being eroded by price wars. Even with similar sales scale, by 2025 profits and cash flow had clearly weakened: operating cash flow fell to RMB 59.1 billion, capex reached RMB 156.8 billion, and free cash flow turned negative at about -RMB 97.7 billion. In 2026Q1, revenue fell -11.82% YoY and net profit attributable to shareholders fell -55.38% YoY. The report's core tension is exactly this: "share is still expanding, but shareholder returns are under pressure." BYD is an "excellent company in a difficult industry," not a "light-asset king in a good industry." Therefore, judging what it "really earns" should focus on the cost-structure moat from vertical integration. Under brutal domestic price wars, that moat is being tested by competitors using different paths to catch up and grind down excess profits. The report's overall rating is Watch: company quality passes, but the current price does not offer a thick margin of safety.

  Jun 4, 2026
• QWhy do customers buy it? Who provides these capabilities?

  A

  One-sentence conclusion: consumers buy BYD because it offers "a better-value electric/hybrid car at the same price point + a safe choice that is unlikely to be wrong"; and the core capabilities supporting this value are almost entirely provided by BYD itself through vertical integration of batteries, motors, electronic controls, and platforms. This is its deepest moat, but it also means BYD must bear the capital spending of the whole chain itself.

  Why do customers buy it? Three layers.

  First, value for money at the same price point, the hardest reason. From the RMB 60,000 Seagull to higher-end models, BYD generally offers longer range, richer configurations, and earlier rollout of intelligent features than peers at the same price. In 2025, it pushed smart driving assistance ("God's Eye") across almost the entire lineup, from entry level to premium. This "low-priced cars can also get high-spec features" approach is exactly what the report repeatedly emphasizes: in the mass market, BYD is a "value for money + technological reliability" brand, not a brand that collects premium pricing through its logo. Second, brand trust: it has ranked first globally in NEV sales for four consecutive years, surpassed Tesla in 2025 to become the world's largest EV seller, and held about 27.2% of China's NEV market. Being the "sales champion" itself is the easiest reassurance for ordinary consumers: if you do not understand cars, buying the one that sells the most is probably not a big mistake. Third, channel availability: a nationwide sales network plus overseas coverage of 119 countries and regions in 2025 makes "easy to buy, easy to service" real. Overseas sales rose 150.7% YoY and finished-vehicle exports exceeded 1 million units for the first time, both according to the report.

  Who provides these capabilities? This is the key: mostly BYD itself. Unlike automakers that rely heavily on external suppliers, BYD has made Blade Batteries, DM-i Super Hybrid, e-Platform 3.0, motors/electronic controls/power semiconductors self-developed and self-produced, with "almost all parts made and owned by ourselves". e-Platform 3.0 integrates the Blade Battery as a structural body component and incorporates an 8-in-1 electric drive system that combines eight major components such as motor, electronic control, transmission, and onboard charger. The Autoliv material in the report also characterizes BYD as a "highly vertically integrated" automaker. In other words, the consumer's "cheap but good enough" experience is not the result of a single upstream supplier giving BYD margin; it is created by BYD controlling cost and iteration speed through vertical integration, then passing part of that benefit to consumers in exchange for volume.

  But "self-supplied capability" is a double-edged sword, and this is why the report only gives "Watch." Because these capabilities are internally provided, BYD must also pay for capacity expansion, new technology, and production footprint itself. In 2025, capex on a cash basis reached RMB 156.8 billion, while operating cash flow was only RMB 59.1 billion, so free cash flow turned negative at -RMB 97.7 billion, and total borrowings jumped from RMB 28.6 billion to RMB 113.4 billion, turning net cash into net debt. Vertical integration allows BYD to internalize profit from multiple value-chain links, but also forces it to bear the capital intensity of the entire chain. The more self-sufficient the capabilities, the heavier the assets and the more volatile shareholder free cash flow. The report's judgment is therefore: company quality passes and the moat is real, but the current H-share price of about HK$91.75 (basically in line with the report baseline of HK$90.2) does not offer a thick margin of safety for conservative investors. The reasonable value range is HK$100–125 and the ideal buying range is HK$60–75. Simply put, the consumer logic for buying BYD is solid, but the "build it ourselves, carry it ourselves" model is a separate calculation for investors.

  Jun 4, 2026
• QWhere will demand growth come from over the next 3–5 years?

  A

  Conclusion first: the main sources of demand growth over the next 3–5 years are "overseas expansion + premiumization," while the domestic mass market is largely a defensive battle in a high-penetration red ocean. But one reminder: the report's core tension applies here too: "demand growth" does not equal "profit growth." Overseas growth must absorb tariffs and local factory costs, while domestic defense must absorb price wars. A rising sales curve does not mean shareholders receive more money. This is the root reason the report keeps the rating at "Watch" and sets the reasonable range at HK$100–125.

  Increment one: overseas expansion, the most certain and steepest source today. In 2025, overseas sales reached 1.046 million units, up 150.74% YoY, and finished-vehicle exports exceeded 1 million units. In 2026, management raised the full-year overseas target from 1.3 million units to 1.5 million units (about +15%). Execution is also showing up: about 320,000 units were sold overseas in Q1, up 55% YoY, and in May overseas sales hit a new monthly high of 160,000 units, +80.7% YoY, already about 42% of total monthly sales. Overseas share is clearly climbing beyond the report's 38.65%, with Europe, Southeast Asia, Latin America, and the Middle East as key battlegrounds. But this growth carries the heaviest "profit discount": cars sold to Europe are still currently made in China and face 27% EU countervailing duties. The Hungary plant has been delayed to small-scale production in 2026, with focus shifting to lower-labor-cost Turkey, which can also use the customs union to bypass EU tariffs. Local factory payback periods are long, exactly matching the report's named uncertainty: whether overseas expansion truly brings higher returns, or is swallowed by tariffs, local plants, and channel investment.

  Increment two: premiumization (Yangwang / Denza / Fangchengbao), aiming to raise unit value and repair margins. In 2025, the three premium brands together sold about 396,500 units, 8.62% of BYD's annual sales, almost double 2024's 4.45%. Momentum continued into 2026: Fangchengbao sold 30,000 units in May, +139.7% YoY, the fastest-growing line; Denza sold about 16,000 units, while Yangwang remained niche. This line directly connects to the report's bullish assumption of whether Denza/Yangwang/Fangchengbao can reach sufficient scale, and it is crucial to whether gross margin can recover from 17.74% in 2025. Objectively, today's premiumization is more about moving into a broader market below RMB 300,000, such as Fangchengbao Tai 3 pre-sale from RMB 139,800 and Denza N9's actual launch price moving lower. The true million-yuan luxury premium segment represented by Yangwang remains small. So "premiumization" is more structural upward movement than a Mercedes/Porsche-style brand rent moat, which is also what the report says.

  Increment three: energy storage and other new businesses, supplementary rather than the main axis. Energy storage, rechargeable batteries, electronics, and related businesses can provide incremental growth and cash-flow buffers, but relative to an auto business contributing about 80% of revenue, they cannot support the core valuation narrative in the short term.

  What about China? Mostly defense. China's electrification penetration had approached 55% in 2025 and is expected to move toward 60% in 2026 (report basis). The blue ocean has become a red ocean. Domestic sales have declined YoY for several consecutive months, and the market relies mainly on trade-in policies, hybrid substitution for fuel cars, and price wars to maintain share. It is worth noting that Q1 gross margin recovered to 18.8%, a near one-year high, largely driven by the rising overseas mix. This proves the opposite side of the argument: future growth quality depends on whether "overseas + premium" can, after absorbing costs, deliver higher unit profitability to the financial statements. If sales are merely larger but profits thinner, the report's concern of "growth that consumes more cash" will be realized. This is the background logic for its 40%–55% permanent capital loss risk warning.

• QIf industry demand grows 5x, which link will run short first?

  A

  Conclusion first: if demand across the NEV industry grows another 5x, the first bottleneck is probably not finished-vehicle manufacturing or battery cells themselves. Those two links are precisely the least scarce today. The links that would become short first and are hardest to replenish quickly are three types of capacity with expansion cycles measured in years: ① upstream battery metals, especially lithium, and refining capacity; ② charging and grid infrastructure; ③ automotive-grade high-end chips, including SiC power devices and intelligent-driving compute. This is the "value-capture point" the Serenity framework is looking for: whoever has supply that is hardest to multiply within a few years controls the future profit bottleneck. Below is a link-by-link breakdown, while also explaining why this question cannot focus only on BYD.

  First exclude the links that look like they should be short but actually are not: finished vehicles and battery cells. This is the most counterintuitive and most important point. Vehicle lines and battery-cell lines usually take only 1–2 years to build, and the entire industry is already in severe overcapacity. China's battery capacity is about 5.6x domestic demand, and utilization once fell to 50% in 2024. Even by 2025Q4–2026, as energy-storage demand recovered, industry battery-cell utilization only recovered to about 73%. In other words, these two links are flexible supply that can "press the expansion button and ramp within two years." If demand grows 5x, capital and production lines will rush in; they are the least scarce and the hardest places to earn excess profits. This echoes the report's core concern about BYD: its strongest finished-vehicle + battery manufacturing links are precisely the links where supply is easy to replicate, price wars are most brutal, and gross margins are pressured. The report's 2025 gross margin decline from 19.44% to 17.74% and free cash flow turning negative at -RMB 97.7 billion are essentially financial reflections of "manufacturing is not scarce."

  Real bottleneck one: upstream lithium and other battery metals, plus refining capacity. Mine expansion cycles are measured in "decades." Hard-rock lithium mines take 10–17 years from exploration to production, and brine projects take 13–15 years. That rhythm cannot keep up with a 5x demand surge. Lithium supply-demand is also flipping from "surplus" back to "shortage": battery-grade lithium carbonate rose from about USD 13,400/ton at the end of 2025 to about USD 26,300/ton by the end of January 2026, almost doubling, and Canaccord and others judge that the lithium market will enter a structural deficit lasting until 2035. Note that in the 2021–22 cycle, the bottleneck was lithium and battery capacity, and subsequent over-expansion drove lithium into surplus. But mines cannot be built in two years like factories. Once demand reaccelerates, lithium, nickel, copper, rare earths, and related materials will tighten earlier and longer than manufacturing capacity.

  Link two: charging and grid infrastructure, likely the hardest and most persistent bottleneck in a 5x scenario. Charging piles themselves can be built quickly, but the grid behind them expands very slowly. Grid infrastructure construction cycles are as long as 5–15 years, while charging piles themselves take only 1–2 years; upgrading substations to support 1MW-level charging hubs takes 18–36 months in most countries. Worse, EV electricity demand is competing with AI data centers for the same grid. Grid interconnection queues have doubled over the past fifteen years, with projects waiting about 5 years on average before interconnection, and transformers, transmission lines, and substation capacity are all tight. A 5x demand scenario means charging power demand surges at the same time. The grid is the physically hardest and slowest link in the whole chain to expand. If electricity cannot get into cars, no amount of vehicles or batteries matters.

  Link three: automotive-grade high-end chips (SiC power devices / intelligent-driving compute). This link has an interesting paradox: even though auto demand is currently slowing and SiC upstream line utilization is only about 50% and device-line utilization about 70%, automotive-grade SiC MOSFET lead times remained above 52 weeks in early 2026, because expansion is constrained by single-crystal growth equipment with multi-year lead times. SiC has almost become the "standard configuration" for modern electric drives (Tesla, BYD, and other mainstream platforms all use it in main inverters). Under 5x demand, substrates and high-end process capacity would hit limits earlier than finished vehicles. This link is more elastic than mines but less elastic than ordinary factories, because Chinese low-cost substitutes and capacity expansion continue to arrive.

  Connecting this back to BYD from the report's perspective: Serenity looks for bottlenecks because profits settle in the hardest-to-copy links. BYD uses vertical integration to internalize batteries, motors, and electronic controls. In today's manufacturing overcapacity and price-war environment, this is a defensive advantage: making things itself is cheaper than buying externally and reduces bottleneck exposure. But BYD itself is not one of the three truly scarce nodes above: it does not control the source of lithium mines, cannot determine national grid expansion, and still largely relies on external supply for SiC. From a value-capture perspective, the players more likely to collect scarcity rents in a 5x demand scenario are upstream lithium resource owners, grid/charging operators and equipment firms, and SiC substrate/device leaders. Automakers, including BYD, sit in the red-ocean links where supply is easiest to expand. This explains why the report assigns a "Watch" rating and emphasizes "an excellent company in a difficult industry" and a thin margin of safety.

  (The above is investment research discussion. NEVs, upstream resources, and semiconductors are all cyclical, high-volatility industries. Price and supply-demand judgments change over time. Do not use this directly as a trading decision.)

• QIs this company the link that will run short first?

  A

  Conclusion first: broadly, no. If NEV demand really grows another 5x and the bottleneck sits in the links hardest to expand quickly, the position that "runs short first and can raise prices from scarcity" is probably not BYD. BYD's main battlefield is power battery manufacturing + finished-vehicle assembly, and these two links are precisely where today's problem is not "insufficient supply" but "too much supply." Its value capture comes from cost leadership + scale, not from "collecting rent at a scarce bottleneck." This also explains the core contradiction in the report: why, even as BYD ranked first in sales for four consecutive years and revenue kept rising, profits and cash flow were falling. The report's 2025 numbers are clear: revenue RMB 803.965 billion, gross margin slipping from 19.44% to 17.74%, net profit attributable to shareholders -19%, and 2026Q1 net profit down -55.38% YoY. A true bottleneck link that can raise prices from scarcity would not lose gross margin while volume rises.

  Why are batteries and finished vehicles not the scarce link? Because capacity in these two areas can expand quickly, and has already over-expanded. China's power battery nominal capacity in 2025 was about 4,800 GWh, while demand was only about 1,000 GWh, pushing industry utilization down to around 50% and driving most players' gross margins below 10%. Finished vehicles are the hardest-hit zone of the price war. Batteries and vehicles are therefore not bottlenecks where "supply cannot be expanded"; they are red-ocean areas where "everyone is expanding until they fight." In a link where supply can be stacked up at any time, nobody can collect scarcity rents for long, including BYD. What it can earn is the cost gap versus peers, not a premium from monopolizing scarce capacity.

  What value does BYD's vertical integration actually capture? It is important to separate "vertical integration" from "exclusive control of scarce links." BYD self-develops and self-produces batteries, motors, and electronic controls, even has its own IGBT chip plants, manufactures about 75% of parts internally, and has moved upstream through lithium rights in Brazil's Jequitinhonha lithium valley, lithium supply with Chile's SQM, and its FinDreams unit refining lithium carbonate and lithium iron phosphate. But the meaning of this integration is more "not being bottlenecked by others" plus retaining part of the profit that would have gone to upstream suppliers. That is the cost and scale moat the report keeps emphasizing. It does not equal monopolizing the genuinely scarce rents upstream. Global lithium mines, charging network operations, and the highest-end automotive/compute chips are all links where BYD is a participant or self-supplier, not the gatekeeper that can charge the entire industry. It has some early positioning in lithium and can smooth cost volatility, but it is far from monopoly pricing.

  So how should we view this against the value-capture chain? The truly scarce, price-setting links are more likely to be high-quality upstream lithium/nickel mines, rare-earth magnets, high-end chips with constrained capacity, or charging/refueling networks with local monopolies. Whoever controls a bottleneck that others cannot bypass during expansion collects rent. BYD's position is to bring "manufacturing + vehicles" to global-best efficiency. It grows the pie and pushes unit costs to the floor, rather than standing at the throat of the chain and charging tolls. This is consistent with the report's "Watch" rating and its emphasis that BYD is an "excellent company in a difficult industry, priced toward the upper end of reasonable rather than cheap enough." Execution deserves respect, but the value-capture method means revenue is easier to grow than profit. The margin of safety must be supplied by a better entry price (the report's ideal buy range is HK$60–75), not by assuming it will automatically enjoy high profits like a scarce bottleneck link.

• QIf this company shut down tomorrow, what would happen to the value chain?

  A

  Conclusion first: it would hurt badly in the short term, but the gap could be filled over the medium to long term. If BYD suddenly shut down tomorrow, the NEV value chain would go through a severe but repairable shock. It is "enormous in scale," but "not irreplaceable." This matches the core characterization in the report: BYD is an "excellent company in a difficult industry (capital-intensive, brutal price wars)," not a choke-point link that others simply cannot replace.

  The short-term shock would indeed be large. In 2025, BYD sold about 4.6 million NEVs, making it one of the world's largest automakers by volume. That year, BEV deliveries were about 2.26 million units, overtaking Tesla, and BYD held about 32% share in China. If such scale disappeared overnight, the shock would transmit through the entire value chain: upstream battery materials, batteries, motors, and electronic control suppliers would see orders collapse, since BYD is both a huge automaker and a massive buyer/self-supplier of batteries and materials; factories and dealer channels would face employment shocks; and a large number of consumers who had ordered, were waiting for delivery, or were using vehicles would be stranded in the short term, with after-sales service, spare parts, and residual values all disrupted. Add BYD's coverage of 119 countries and regions and 2025 finished-vehicle exports exceeding 1 million units, and the shock would be global, not only domestic.

  But over the medium to long term, it is replaceable; the value chain would not face an "unfillable" gap. The key is that BYD occupies "finished-vehicle manufacturing + self-developed/self-produced electric powertrain" — one of the most competitive and crowded links — not the industry's scarcest bottleneck. Its vacated share would be quickly divided up. Tesla (still delivering about 1.64 million units in 2025), Geely, and many Chinese automakers have existing capacity and technology to absorb demand. For consumers, the next car purchase can simply shift to another brand. NEVs do not have switching lock-in where "only BYD will do." Upstream materials and battery capacity are already multi-supplier systems; once demand shifts to other automakers, they can largely re-match supply after a period of painful capacity reallocation.

  The difference is clear when compared with truly irreplaceable links. For choke-point nodes such as certain high-end lithography tools or the most advanced process chips, a supply cutoff leaves the whole industry unable to find substitutes in the short term and can stop the entire chain. That is "unfillable." BYD is not in that category. It is "huge in scale and extremely strong in execution, but replaceable." This matches the judgment in question 6 of this Q&A set: BYD is not the scarcest link in the value chain. That is why the report positions it as "a good company in a difficult industry" and gives a "Watch" rating. Its moat is "scale and cost structure that are very hard to catch," not "others cannot bypass it at all."

• QCan customers replace it? How long would it take? How many years would new entrants need?

  A

  Conclusion first: this question has two halves, and both are not very favorable to BYD. Customers can replace it at any time, although slowly; and "new entrants need years" is no longer protective in China's NEV track. This is the root of the report's judgment that switching costs are "medium to weak," domestic mass-market pricing power is "narrowing," and the moat is "scale and cost structure that are hard to catch" rather than "others simply cannot replace it."

  First half: can C-end customers replace it? Yes, and switching costs are low. A car is a one-time durable consumer good. It is not a subscription and has no ecosystem lock-in. After consumers buy a car, the next replacement usually comes several years later. At that time, whether they buy BYD again or switch to another brand involves almost no friction, unlike switching phone systems and migrating data or changing SaaS workflows. BYD retains customers through product strength, reliability, and brand reputation, not by locking people in. The report directly rates "switching costs" as medium to weak, and marks "does it have pricing power" as uncertain: some overseas and in premium segments, weak in the domestic mainstream market. In other words, customer "loyalty" must be re-earned with every product generation; it is not held by contracts or ecosystems. This is weak stickiness.

  Second half: how many years do new competitors need? Barriers are indeed medium to high, but in reality they no longer constitute a moat. Building a competitive automaker requires years, hundreds of billions to trillion-level capital, supply-chain coordination, and channel rollout. The report says the same: copying BYD "requires both years of R&D accumulation and hundreds of billions to trillion-level capital." The issue is that this "takes years" barrier has already been collectively crossed by a group of mature players in China. The clearest example is Xiaomi: the project was launched in 2021, and the first SU7 deliveries began in March 2024, about three years from zero to mass production; by 2026Q1, cumulative deliveries had reached about 80,000 units, placing it among the top three NEV makers by sales, with more than 650,000 units delivered over 24 months. Add Tesla, Geely, Li Auto, Xpeng, Chery, and many others, and the track is not "waiting for newcomers to slowly enter"; it is already crowded and fighting at close range.

  Putting the two halves together: BYD cannot retain customers through lock-in, and it sits in an overcompetitive market where a new player can reach the table in three years and where 2026 is still an "elimination round," with the industry expecting 5–8 weaker automakers to exit. This is the underlying reason its pricing power is limited and price wars consume scale dividends. It also echoes the report's repeated characterization: BYD is an "excellent company in a difficult industry." The moat is real but "not rent-like." Cost and scale are widening, while pricing power in the domestic mass market is narrowing. In valuation terms, this is one reason the report gives a "Watch" rating and requires a 25%–30% margin of safety. A very strong company that cannot monopolize excess profits through barriers deserves long-term tracking, but should not loosen buying discipline when the price is not cheap enough.

• QCan supply expand? What conditions are needed?

  A

  Conclusion first: in the finished-vehicle and power-battery manufacturing links where BYD operates, supply expansion has almost no hard constraints. The threshold is "money, land, engineering, and time," not any scarce resource. Precisely because supply is so easy to expand, the whole industry has fallen into overcapacity + price wars, and excess profits are continuously compressed. This is the most important and unfavorable point when viewing BYD through the Serenity "value capture" framework: links whose supply can be quickly replicated cannot capture scarcity rents over the long term. The report already characterizes this: it calls BYD an "excellent company in a difficult industry" and a "capital-intensive, brutally competitive automaker." That is the essence of the issue.

  What conditions are needed for expansion? Basically capital + execution. The most direct evidence is BYD itself. The report discloses that 2025 cash capex for purchasing and constructing fixed assets and similar items reached RMB 156.808 billion, far above that year's RMB 59.136 billion operating cash flow, directly driving free cash flow to -RMB 97.7 billion and total borrowings from RMB 28.6 billion to RMB 113.4 billion. In other words, when BYD wants to expand capacity, it can do so; the cost is burning cash, adding leverage, and sacrificing shareholder cash flow, not fighting for scarce licenses or exclusive raw materials. The same applies to power batteries: global battery manufacturing capacity has doubled since 2022, exceeded 200GWh in 2024, and nearly 700GWh was under construction, while average battery pack prices fell to a historical low of about USD 108/kWh in 2025. Capacity and costs are arriving quickly; this is not a bottleneck.

  The direct consequence of easily expanding supply is industry-wide overcapacity. Third-party data shows that China's overall auto-industry capacity utilization was only about 49.5% in 2024, and China's EV capacity utilization was only about 64.5% in March 2025, with industry excess capacity of roughly 5 million–10 million units per year. The result is that most automakers "sell a lot but lose money because price cuts outpace cost reduction". BYD is a winner in this fight: its plant utilization has long stayed above 80%–90%, and it holds about 27% of China's EV retail market. But "winning" only means losing less and having more share; it does not let BYD escape price wars. This matches the report's core contradiction: scale keeps expanding, but profits and cash flow fall — 2025 gross margin from 19.44% to 17.74%, net profit attributable to shareholders -19%, and 2026Q1 net profit -55.38% YoY. Weak supply constraints are the structural reason BYD finds it easier to grow revenue than profit, and one underlying reason the report gives "Watch" rather than "Buy" and emphasizes a thin margin of safety.

  The links that are truly hard to expand and may become bottlenecks are further upstream, not in BYD's main link. First is minerals: lithium mining, refining, and processing capacity still has clear gaps, and the market may shift from surplus to structural shortage around 2029. Second is charging infrastructure, where expansion is constrained by grids, land, and investment payback cycles, much slower than building a vehicle line. These are the links Serenity asks investors to focus on when asking "who runs short first if demand rises 5x." But most are not where BYD currently earns excess profits. Honestly: BYD's manufacturing moat (cost, scale, vertical integration) is enough to keep it leading and living better than peers in brutal competition, but the fact that its link has weak supply constraints means it is hard to convert leadership into long-term, stable, fully priced excess returns. Investors must separate this from whether it is a good company. The report's answer is: the company is strong, but the industry does not offer a generous profit pool.

  Jun 4, 2026
• QWhich link in the value chain will profits ultimately flow to?

  A

  Conclusion first: in the NEV chain, profits are concentrating at the "two ends" — upstream scarce resources such as lithium/mines and links with pricing power, such as battery leaders and vehicle makers with brand or intelligence premiums. The middle link of "finished-vehicle manufacturing" itself is the thinnest and most easily consumed by price wars. BYD's special feature is that it uses vertical integration to retain inside the company part of the profit that would otherwise go to battery and component suppliers, but its main battlefield is still trapped in finished-vehicle manufacturing, where profit is hard to capture stably. This is exactly why the report gives "Watch" and emphasizes that BYD is an "excellent company in a difficult industry."

  Breaking down where profit goes along the chain:

  • Upstream lithium/minerals: this is a highly cyclical link, alternating between windfall profits and deep losses; it is not a "stable profit pool." In 2025, lithium prices once fell to about RMB 58,000/ton, breaking the cost lines of many high-cost projects, forcing high-cost mines either to halt production or endure losses. In 2026, lithium carbonate prices rebounded quickly, rising about 72% during the year and breaking above RMB 200,000/ton. Upstream can take excess profit in some years, but it is hard to expect stable annual contribution. It earns cyclical money.
  • Battery leaders: this is currently the chain's strongest value-capture segment. The contrast is clear: CATL's 2025 net profit attributable to shareholders was about RMB 72.2 billion, +42.28% YoY, overall net margin 18.12%, power battery gross margin about 23.84%, and global power battery share about 39.2%. BYD, as an automaker in the same period, had net margin of only about 4.1% and gross margin of 17.74% (see the report's financial table). Both sell electric mobility value, but the battery leader that controls a key link through technology + scale earns materially higher unit margins than vehicle assembly.
  • Finished-vehicle manufacturing (pure assembly): the report characterizes this industry as "capital-intensive, cyclical, brutally competitive, and unstable in profit." It is the easiest link for price wars to swallow scale dividends. This is why BYD's 2025 "sales kept rising, but profit and cash flow fell," and why 2026Q1 revenue was -11.82% and net profit attributable to shareholders -55.38%.
  • Vehicle makers with brand/intelligence premiums: the firms that can earn excess profit are those for which consumers "recognize the brand and willingly pay for software/autonomous driving premiums" (Tesla's valuation contains substantial AI/Robotaxi option value). BYD is moving up with Denza, Yangwang, and Fangchengbao, and the report mentions brands such as Denza trying to shed a low-price image. But the report's judgment is that premiumization "is trying to happen, but is far from consumers recognizing only the brand and ignoring price."
  • Charging/services/software: these are forming new profit pools, but they are not yet the dominant contributor to BYD's overall profit.

  Where will the largest future profit be bottled up? The report's logic points to a somewhat harsh answer for BYD: not in BYD's main battlefield of finished-vehicle manufacturing itself, but more likely at the two ends: upstream scarce resources and brand/intelligence premiums. BYD's real moat — cost, scale, vertical integration — essentially means it has "eaten" the fatter battery, motor, and electronic-control links itself, giving it a higher gross margin than a pure assembler. The report also lists vertical integration as its strongest moat. But this is the ability to "retain supply-chain profit internally," not proof that finished-vehicle manufacturing naturally captures stable excess profit.

  What this means for investors in the stock: as long as BYD remains in a structure where "finished-vehicle profit is hard to capture stably + domestic price wars suppress pricing power," its returns depend heavily on whether two things materialize: whether overseas markets bring higher margins than China, and whether premium brands truly build pricing power. The report's reasonable value range is HK$100–125, ideal buy range HK$60–75, versus the current H-share price around HK$91.75 (basically in line with the report baseline of HK$90.2). It says the current price is "toward the upper end of reasonable, with a thin margin of safety," and warns of about 40%–55% permanent capital loss risk. That is because if those two things fail, the market will reprice BYD from a "growth leader" to an "ordinary automaker," and finished-vehicle manufacturing is inherently one of the hardest links in this chain in which to defend profit.

  Jun 4, 2026
• QHow large is the company's profit elasticity? If revenue grows 10%, how much would profit grow?

  A

  Conclusion first: you cannot simply apply "revenue +10% → profit +X%." BYD is a typical asset-heavy, high-fixed-cost manufacturer (2025 R&D expense RMB 57.978 billion and depreciation of fixed assets as high as RMB 72.047 billion). In theory it has strong positive operating leverage: if incremental revenue spreads these fixed costs, profit elasticity can exceed 1. But in reality, the past year has shown negative elasticity. So the real answer is: the direction of elasticity depends on whether that 10% growth comes from "price cuts for volume" or from "pricing/structural upgrading for volume."

  First, why positive leverage exists in theory. R&D, capacity depreciation, and fixed manufacturing/channel costs are costs that have already been spent and sit there. If BYD sells more cars without cutting prices, the marginal cost of each additional car is far below the selling price, and a large share of incremental gross profit can fall to operating profit. Profit growth would then outrun revenue growth. That is the scale flywheel in its ideal form, and it is what happened in 2021–2024: revenue rose from RMB 216.1 billion to RMB 777.1 billion, and net profit attributable to shareholders rose from RMB 3.0 billion to RMB 40.3 billion. Profit grew much faster than revenue, and positive leverage was realized beautifully.

  But since 2025, the direction of leverage has reversed. In 2025, revenue was still growing (RMB 803.965 billion), but net profit attributable to shareholders fell about 19% YoY. By 2026Q1, revenue fell -11.82% YoY and net profit attributable to shareholders fell -55.38% YoY — the profit decline was nearly 5x the revenue decline. That is amplification, but downward amplification. The root is gross margin: 2025 gross margin fell from 19.44% in 2024 to 17.74%, and the Q1 price war reached its fiercest level in two years in March, directly thinning unit gross profit and causing profit to decline for four consecutive quarters. The logic is simple: price cuts hit gross margin directly; every unit of price concession removes one unit of incremental gross profit while fixed costs do not fall. Revenue gained through "price-for-volume" can be swallowed by price concessions before scale benefits appear. This is exactly the report's repeated point: "rising sales and industry position do not guarantee simultaneous increases in margins and free cash flow."

  So the 10% must be viewed through two types of growth quality:

  • If the 10% comes from overseas + premiumization, it is likely positive elasticity. This growth is not driven by discounting. Overseas and higher-margin brands such as Denza/Yangwang can raise average selling prices and gross margins, so incremental revenue can truly spread fixed costs and amplify profit. In Q1, overseas sales grew +55.84% YoY and already accounted for 45.85% of NEV sales; this is the part that currently looks most like positive leverage.
  • If the 10% is squeezed out by continued price cuts in the domestic mainstream market, it is likely negative elasticity or revenue growth without profit growth. Revenue rises on paper, but gross margin is dragged by price wars, and profit may stand still or even fall, as it did in Q1.

  In one sentence: BYD's operating leverage is a double-edged sword. Its asset-heavy structure means the "amplification" attribute is certain, but whether it amplifies profit or pain depends on whether growth comes from price increases or price cuts. This is why the report rates it "Watch" and lists "whether group gross margin can hold and whether overseas/premium mix can rise" as key indicators. Before understanding the quality of that 10%, any linear extrapolation of "revenue +10% → profit +X%" will be misleading.

  Jun 4, 2026
• QHas the market already discovered this company, or has it not yet realized all this?

  A

  Conclusion first: BYD is not an undiscovered obscure stock. Quite the opposite — it is one of the most closely watched and fully priced names. The real "expectations gap" in this closing question is not "the market has not seen how good it is," but whether this already well-recognized "goodness" is worth today's price. This is a visible bull-bear debate, not an information gap.

  How "discovered" is it? It has ranked first globally in NEV sales for four consecutive years, sold about 4.6 million units in 2025, and exceeded 1 million exports for the first time. It is itself an industry headline. Sell-side coverage is extremely dense: currently about 28 institutions cover the H shares, with a consensus rating of "Strong Buy" (26 Buy / 3 Hold / 1 Sell) and a 12-month average target price of about HK$124.5. More tellingly, even the smart money that first "discovered" it has exited: Berkshire Hathaway fully sold in 2025 the BYD position it had held for 17 years and that returned more than 20x. A star stock followed by 28 investment banks and once backed by Munger is, by definition, not a stock that "has not yet been noticed."

  Where, then, is the expectations gap? It splits in two opposite directions:

  • Bull view: the market may still underestimate the long-term value of BYD's globalization and vertical integration. Overseas sales grew +150.7% YoY in 2025, coverage reached 119 countries, and management points to a 2026 overseas target of 1.5 million units. If global localization and premiumization (Denza/Yangwang/Fangchengbao) are realized, the current premium to Geely at about 11x PE can stand, corresponding to the report's reasonable range of HK$100–125 or even the optimistic range.
  • Bear/report view: the market has overpaid for the "sales miracle" and underestimated price-war erosion of profits. The report repeatedly emphasizes the contradiction of "scale keeps expanding, but shareholder returns are under pressure": 2025 gross margin fell from 19.44% to 17.74%, net profit attributable to shareholders fell -19%, free cash flow turned negative at about -RMB 97.7 billion, and total borrowings jumped from RMB 28.6 billion to RMB 113.4 billion; 2026Q1 revenue -11.82% and net profit attributable to shareholders -55.38% were signs that this expectations gap had begun to materialize.

  So the honest answer is to hold both sides rather than choose one simplistically: the market has long "discovered" that BYD is strong; the real dispute is whether known quality is worth today's price. This is exactly why the report gives a "Watch" rating and judges the current H-share price (HK$90.2 on the base date, about HK$91.75 as of 2026-06-04, basically unchanged) to be "toward the upper end of reasonable, with a thin margin of safety." It sits near the lower end of the report's reasonable intrinsic value range of HK$100–125: not a buried bargain, but not clearly overvalued either (above HK$130). The report's ideal buying range is HK$60–75, requiring a 25%–30% margin of safety, and it warns that if valuation reverts to book value or depressed earnings multiples, there is about 40%–55% permanent capital loss risk. In other words, buying BYD is not buying an expectations gap others have missed; it is deciding whether to wait for a thicker discount in a strong company that is already fully recognized.
