Jabil Inc.: An In-Depth Value Investing Analysis

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 an entirely new market?5/10

  A

  Conclusion first: Jabil is "expanding an existing pie," not creating a brand-new market — and within that pie, the slice it captures is inherently thin. Measured against Baillie Gifford LTGG's "five times in ten years" yardstick, the ceiling's absolute height is not low, but Jabil sits in the low-bargaining-power contract-manufacturing layer of a high-growth track, so its blue-sky upside is structurally capped.

  Start with how big the pie is and how fast it is growing. Jabil operates in electronics manufacturing services (EMS), a mature outsourcing business. Third-party research generally puts the global EMS market's 2025-2030 CAGR at around 5.6% (about $648.5 billion in 2025 rising to about $853 billion in 2030). This is a huge but slowly expanding existing pie, driven by electrification, rising complexity, and cost outsourcing, not by any disruptive new demand appearing from nothing. In other words, at the industry level there is no "creating a new market" story.

  What is genuinely growing fast is the AI / cloud data center corner of that pie. Per the report, management guided FY2026 Intelligent Infrastructure segment revenue to about $16.5 billion, up 34% year over year, with cloud and data center infrastructure at about $10.4 billion, up 41%; by the first half of FY2026 that segment's revenue share had already risen to 47%. The most recent quarter was even stronger — Q2 FY2026 segment revenue grew 52% year over year and already accounted for about 49% of total revenue. So it is true that "the ceiling is rising," but what is lifting it is the AI infrastructure wave, not Jabil opening up new territory on its own.

  But what Baillie Gifford really wants to ask is: within this expanding pie, how thick a slice can Jabil cut, and can it hold onto it? This is where it diverges from a "great growth stock." The report is blunt about the profit pool: in the EMS business, "the profit pool is not concentrated in the hands of the contract manufacturer — it flows mostly to core brand owners, chipmakers, and system designers," and Jabil's long-run gross margin sits at just 8%-9%, with core/segment margin only 5%-5.7%. It is building power, liquid cooling, racks, and systems for stronger customers like Nvidia and hyperscale cloud players, and orders, pricing, and the pace of capital spending all sit in the customers' hands. The bigger the pie gets, the slice Jabil captures stays thin and dependent on others.

  So the honest answer is: the "height" of the ceiling is propped up by the genuine AI infrastructure wave, and the absolute size is large enough. But Jabil's role determines that its "way" of sharing that ceiling is low-margin, customer-dependent contract manufacturing, not a market-defining platform that captures its own premium. It is expanding an existing pie, not creating a new market — which is exactly why it can be a "good company in a bad industry" but struggles to become a "great company in a good industry."

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

  A

  Conclusion first: doubling revenue over the next five years (about 15% annualized) is a high-difficulty, non-base-case scenario for Jabil — the more realistic path is mid-to-high single-digit to low double-digit growth, driven by "volume" (AI/cloud infrastructure order ramp) rather than "price," with new businesses just an extension of the same core line. Betting on a doubling is, in essence, betting that the Intelligent Infrastructure leg keeps its current explosive pace for multiple consecutive years.

  Start with the current real growth slope. Jabil's headline revenue over the past two years is not actually exciting: FY2025 full-year net revenue was about $29.8 billion, up only 3.2% year over year (about $28.9 billion in FY2024 and about $34.7 billion in FY2023, during which the company also divested its Mobility business, so the headline number was held down by portfolio adjustments). But entering FY2026, growth has clearly accelerated: the report shows FY2026 first-half total revenue up 20.9% year over year, and the most recent quarter, Q2 FY2026, brought in about $8.3 billion in revenue, up 23% year over year. Management has guided full-year FY2026 revenue to about $34 billion. Going from the roughly $29.8 billion FY2025 base to "doubling in five years" means reaching close to $60 billion — that is, sustaining roughly 15% annualized growth for multiple more years on top of an already-enlarged base.

  The growth driver is "volume," not "price." The report repeatedly emphasizes that Jabil lacks strong pricing power: long-run margins sit at just 5%-6%, tariff costs are mainly passed through to customers, and the company explicitly acknowledges that "if costs cannot be fully passed through, margins and cash flow will suffer." So the engine of revenue growth is order volume — specifically demand for power, liquid cooling, racks, networking, and capital equipment in AI / cloud data centers. In Q2 FY2026, Intelligent Infrastructure grew 52% year over year and already accounted for about 49% of total revenue; per the report, management expects the segment to reach about $16.5 billion in FY2026 (+34%), with cloud and data center at about $10.4 billion (+41%). This leg is genuinely "taking over" growth.

  But it would be risky to extrapolate a "five-year doubling" from this, for three reasons. First, the volume growth is highly concentrated and reversible: the report discloses that the top five customers accounted for about 36% of revenue in FY2025, rising to about 38% in the first half of FY2026, with one anonymous customer alone accounting for 16%, concentrated mainly in this segment — once hyperscale customers' capex shifts from "explosive" to "normalized," volume would collapse. Second, the other two legs (Regulated Industries and Connected Living) show flat growth, so it is unrealistic for the II leg alone to carry a doubling. Third, the so-called "new businesses" (the first-half-FY2026 acquisitions of Hanley Energy and Rebound Technologies) are aimed at strengthening data center energy and cooling capabilities, still an extension of the same core line rather than opening an independent second growth pole.

  So the honest answer: whether revenue can "at least double" over the next five years is most likely not a reasonable base-case expectation, but if the AI infrastructure supercycle persists, getting close to a doubling is not far-fetched. Growth is driven mainly by volume (AI/cloud order ramp), price contributes almost nothing, and new businesses are just reinforcement of the same engine. Baillie Gifford would acknowledge this as a real, steep growth curve that is highly dependent on a single external cycle, rather than a self-driven, predictable compounding machine.

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

  A

  Conclusion first: Jabil's "second curve" already exists today, and it is taking over right now — it is Intelligent Infrastructure (AI / cloud data center infrastructure); but the problem is that this curve has itself already become the "present-tense first curve," and the true "next baton" — who takes over once the II boom fades — is not yet visible today. This is exactly where Baillie Gifford would dock points: the current engine is visible, but the engine after that is not.

  First confirm that the current handoff is real. Jabil's past main curve was consumer electronics / Mobility contract manufacturing; the report notes the company divested its Mobility business in 2024, shifting weight decisively to Intelligent Infrastructure. This new curve is not "future tense" — it is already running: per the report, the II segment's share was about 41% in FY2025, rising to 47% in the first half of FY2026, and that segment grew 52% year over year in Q2 FY2026, accounting for about 49% of total revenue; management guided full-year FY2026 revenue to about $34 billion, of which II is about $16.5 billion and cloud and data center about $10.4 billion. So strictly speaking, Jabil has already completed one curve switch (consumer electronics to intelligent infrastructure), and that deserves credit.

  But Baillie Gifford's question is about "what takes over as the next engine five years from now." Pushing the timeline out past the point where AI infrastructure capex normalizes, the "next-baton candidates" Jabil can actually point to are fairly weak:

  • Deepening into data center energy and thermal management. The first-half-FY2026 acquisitions of Hanley Energy (data center power infrastructure) and Rebound Technologies (refrigeration/cooling) are aimed at extending the company from "building server racks" toward "building data center power and cooling systems." This makes sense, but it still rides on the same AI infrastructure wave rather than being a new engine independent of it — when the wave recedes, these recede with it.
  • Complex-manufacturing upgrades in other segments. Regulated Industries (healthcare, automotive, renewable energy) has durable demand and relatively high switching costs, but per the report its growth is flat, making it hard to independently carry the "handoff" role.

  An even more important honest signal: the report itself lists "II growth stalling, FY2027 outlook weakening" as its top "trigger for reassessment," and describes the worst realistic scenario as "AI narrative cooling + multiple compression + margin decline," with the share price potentially reverting to $150-$220 (40%-60% downside from the current level of about $364). In other words, the company does not currently have a mature second curve that is weakly correlated with II and could cushion the business once II fades.

  So the answer to this question has two layers: as "the current engine," the next engine genuinely exists today and is already taking over (II / AI infrastructure); but as "the curve after II," today there is only directional energy/cooling reinforcement, not yet grown into an independent, verifiable new growth pole. For Baillie Gifford, the former earns Jabil a place on the "growth-stock watchlist," while the absence of the latter explains why it is hard to treat as the kind of "curve after curve, perpetually self-renewing" candidate for five times in ten years.

• QWhat is its core competitive advantage? Will this moat widen or narrow over the next three to five years?4/10

  A

  Conclusion first: Jabil's core competitive advantage is a composite moat of "scale + global footprint + complex-manufacturing certification + customer onboarding capability + operating culture" — hard to replicate but contestable, definitely not a wide moat. Over the next three to five years, this moat will most likely "widen slightly" (benefiting from rising project complexity and switching costs brought by AI infrastructure), but the degree of widening is limited and does not change its underlying nature of "serving powerful customers on thin margins." The report rates moat strength at 2.5/5, and I agree with that magnitude.

  Start with what the advantage actually is, and how strong it is. The report breaks down the moat dimension by dimension clearly, with a few key points:

  • Brand and network effects are essentially zero: end consumers have no awareness of Jabil at all, and there is no platform network effect. These two are the true sources of a wide moat, and Jabil has neither.
  • Scale and cost advantage: moderate (on the strong side): Jabil is one of the world's top EMS providers, with a self-selected peer group of Celestica, Flex, Hon Hai, Plexus, and Sanmina, and the report puts its facility footprint at about 35 million square feet. Global delivery and procurement capability can push down unit costs, but profit remains thin — the cost advantage has not translated into pricing power.
  • Switching costs: moderate: in complex or regulated segments such as healthcare, automotive, and cloud data center power/cooling/racks, validation, switching, and re-certification costs are relatively high. This is the most substantive part of Jabil's moat, and the part most likely to deepen over the next three to five years.

  Why "hard to replicate but contestable"? The report's logic is: replicating Jabil's global footprint genuinely requires years and billions of dollars of investment; but competitors like Flex, Celestica, Sanmina, and Plexus are already on the field and are chasing the same AI infrastructure orders. The moat keeps out new entrants, but not existing peers. A direct comparison: Celestica has already raised its 2026 guidance to $19 billion in revenue with an adjusted operating margin of 8.0% — clearly higher than Jabil's guided 5.7% core operating margin, showing that within the same AI pie, a rival with a deeper moat and better customer/product mix can capture a thicker slice of profit. Jabil is not without competitiveness, but it does not dominate peers on the "price/quality" match.

  Will it widen or narrow over the next three to five years? My judgment is a slight widening, but with a ceiling. The case for widening: power, liquid cooling, racks, and system integration for AI data centers are growing more complex, and the report notes this will raise customer validation and switching costs, deepening the most substantive part of the moat; the first-half-FY2026 acquisitions of Hanley Energy and Rebound are also reinforcing this capability. But the widening has a ceiling — because the customers Jabil serves are precisely the ones with stronger bargaining power. The report points out that these customers "hold greater initiative over pricing, capex pacing, and order allocation," and the top five customers accounted for about 36% of revenue in FY2025, rising to about 38% in the first half of FY2026. The more concentrated and powerful the customers, the more the "pricing" value of the moat is siphoned away by them.

  So the honest answer: the core advantage is an operational, composite moat (scale/certification/switching costs/execution), in the "moderate, stable to slightly improving" tier — far from the ever-widening class of Coca-Cola, Visa, or ASML. Over the next three to five years it will widen slightly as AI infrastructure complexity rises, but the structure of "powerful customers + thin margins" is unchanged — this moat gets a bit deeper, but it will not become a moat among moats.

• QIf its core business were disrupted, does it have the DNA for self-reinvention? How does it handle mistakes and bad news?5/10

  A

  Conclusion first: Jabil has real-world evidence of "switching tracks and reshuffling its portfolio," and a governance backdrop of relatively honest bad-news disclosure — but its "self-reinvention" is an operational reinvention that passively adapts to customers and the cycle, not a DNA-level reinvention that proactively defines the future and dares to disrupt itself. On this Baillie Gifford question, Jabil earns a middling score of "can pivot, but is not innately inclined to disrupt itself."

  First, has "self-reinvention DNA" actually been tested? Yes, and it was a real, hard-money pivot. The report records a string of portfolio adjustments: divesting the Mobility (consumer electronics contract manufacturing) business in 2024, shifting weight to the higher-quality Intelligent Infrastructure; disposing of the Italy business in 2025 (recognizing a loss); and acquiring Hanley Energy (data center power) and Rebound Technologies (cooling) in the first half of 2026. The result is a revenue mix that has shifted from consumer-electronics-dominated to AI/cloud-infrastructure-dominated — in Q2 FY2026, Intelligent Infrastructure already accounted for about 49% of total revenue, up 52% year over year. Completing this kind of main-curve migration within a few years shows that Jabil is not a rigid contract manufacturer clinging to old businesses until they die off; its portfolio-reallocation capability is real.

  But the "nature" of this reinvention needs to be seen clearly. It is adaptation that follows customers and the cycle, not "starting over from scratch when the core business is disrupted." The reason Jabil could pivot to AI infrastructure is that its hyperscale customers directed their capex there, and Jabil rode along, migrating its capacity, procurement, and certification capabilities accordingly. This is not the same thing as the "self-reinvention DNA" Baillie Gifford has in mind (a company, after its core is disrupted, growing a brand-new, self-defined growth pole out of its own vision and culture). In fact, the report describes the worst-risk scenario as "AI narrative cooling + multiple compression + margin decline" and does not offer an endogenous answer to "what would Jabil rely on to save itself if II were disrupted" — this is exactly the weak point of adaptive reinvention: it follows the wave wherever it goes, and when the wave recedes, it lacks an independent backstop engine.

  Now look at "how it handles mistakes and bad news" — this is the other side of judging reinvention DNA, since a company that is willing to admit mistakes is the kind that can actually change itself. Here Jabil's track record leans positive:

  • Candid disclosure. The report cites multiple instances of the company proactively acknowledging unfavorable facts: explicitly stating that "if tariff costs cannot be fully passed through, margins and cash flow will suffer," admitting that receivables/inventory/prepayments all rose in the first half of FY2026 (to support third-quarter sales and the timing of customer-controlled consignment purchasing), and truthfully disclosing the loss from the 2025 Italy business disposal. Not avoiding bad news is the precondition for correcting mistakes.
  • Shareholder-friendly governance framework. The report notes management incentives factor in core operating income, core operating margin, free cash flow, three-year EPS growth, and relative TSR, and the company also updated its compliance clawback policy in 2023 — a mechanism for "recovering bonuses when mistakes occur" — which is a hard constraint on how it treats errors.
  • Honest room on cash-flow accounting. The report also flags that the company makes heavy use of receivables sale / securitization programs ($11.4 billion in receivables sold in FY2025, plus another $8.5 billion sold and $2.1 billion securitized in the first half of FY2026), all of which are counted in operating cash flow. The report's stance is "not a red flag, but free cash flow quality should be discounted somewhat" — laying the accounting bare and letting readers apply their own discount is itself a sign that the disclosure is open.

  So the honest answer: Jabil possesses the qualities of "being able to pivot, willing to admit mistakes, and constrained by governance," and has successfully completed a portfolio reinvention in the past; but its reinvention is operational adaptation pulled along by customers and the cycle, lacking the DNA of "regenerating itself after the core is disrupted." On mistakes and bad news, it is generally honest, discloses fully, and is constrained by a clawback policy — which gives confidence in management's credibility, but is not the same as possessing the kind of reinvention power, in the Baillie Gifford sense, that dares to disrupt itself.

• QDoes management (especially the founder) have a long-term view, with interests deeply aligned with the company? Would it sacrifice current profit for the sake of five to ten years from now?4/10

  A

  Conclusion first: Jabil's management leans positive on "long-term view + interests largely aligned + rational capital allocation," but the alignment mechanism relies on compensation structure and stock-ownership requirements rather than founder-style large personal holdings; it is willing to optimize the portfolio for the long term, but is not willing to, and has no need to, sacrifice current profit for "five to ten years from now" (because it is already a mature, steady cash-generating company, not a growth business that burns cash for the future). On this question Jabil earns a mid-to-upper score, but it lacks the extreme alignment Baillie Gifford values most — the kind where a founder holds a huge stake and is willing to accept long-term losses for the distant future.

  Start with the "people." The report notes that current CEO Michael Dastoor has held the role since May 2024, was CFO for a long stretch before that, and joined Jabil back in 2000 — a deeply internally groomed executive: stable, knows the company, not a parachute hire. But he is not the founder. The proxy statement discloses his holdings at only about 33,407 shares, well below former CEO and current Executive Chairman Mark Mondello's roughly 1,109,400 shares. I agree with the report's read here: this is more likely because Dastoor has been CEO for a short time and equity accumulation is still in progress, rather than a sign of misalignment. But the objective result is that current management's alignment with shareholders rests mainly on compensation design and stock-ownership requirements, not on already-large personal holdings staked on the company. Compared with the founder-net-worth-tied-to-the-company style Baillie Gifford prefers, this is a clear discount factor.

  Next, whether the "alignment mechanism" is adequate. The governance framework the report records is actually quite shareholder-friendly: incentive metrics include core operating income, core operating margin, free cash flow, three-year EPS growth, and relative TSR; the CEO stock-ownership requirement is 6x annual salary, and 3x annual salary for the CFO and executive vice presidents; the compliance clawback policy was also updated in 2023. This mechanism bakes "long-term, per-share, cash flow" into the scorecard — the direction is right, and it uses institutional design to fill the gap left by "personal holdings not being large enough."

  The hardest evidence for "long-term view" is capital allocation — this is also where Jabil's management most deserves a high score. The report notes the company clearly favors buybacks over dividends: about $1.030 billion in buybacks in FY2025, about $2.404 billion in FY2024, and about $487 million in FY2023, while dividends run only $30–45 million per year. More importantly, it has actually delivered per-share value — shares outstanding fell from about 136 million at the end of FY2023 to about 107 million at the end of FY2025, a roughly 20.7% reduction over two years by the report's count, and nearly 30% cumulatively since 2019. This is a real, dollars-on-the-table per-share value orientation, not just talk.

  But the question of "willing to sacrifice current profit for five to ten years from now" needs a different angle for Jabil. Baillie Gifford's question targets Amazon-style companies that deliberately suppress current profit for the future over the long run; Jabil is not that type — it is a mature, steady, consistently cash-generating, thin-margin manufacturer, and FY2026 guidance still calls for core EPS of $12.25 and adjusted free cash flow above $1.3 billion. Its way of "playing for the long term" is divesting lower-quality businesses, concentrating resources on AI infrastructure, and continuing buybacks — not deliberately giving up current profit for a distant strategy. So strictly speaking, it has not shown the behavior of "sacrificing current profit for five to ten years from now" — but this is more a function of its business model than short-termism.

  An honest caveat (and one the report explicitly flags as a lingering concern): the "rationality" of capital allocation has a tail that still needs to be verified. The report withholds a full score because heavy buybacks in prior years, done at much lower price ranges, worked out well in hindsight, but with the stock now at a high of about $364, the marginal appeal of continuing to lean on buybacks has clearly declined; meanwhile, whether bolt-on acquisitions like Hanley Energy and Rebound generate returns above what buybacks would still needs time to prove out. If mechanical buybacks at high valuations or a large, expensive acquisition were to occur, confidence in "continued growth in per-share intrinsic value" would take a hit.

  So the honest answer: Management has a long-term view (evidenced by portfolio reshaping and aggressive, effective buybacks), interest alignment is largely in place (via compensation structure and stock-ownership requirements, rather than large founder holdings), and capital allocation is generally rational. But it lacks the extreme founder-style alignment Baillie Gifford values most, and it does not belong to the category of companies that deliberately sacrifice current profit for the distant future — these two points mean that on the "management" dimension it is a trustworthy top performer, but not the kind of figure whose fate is deeply bound to the company in the Baillie Gifford narrative.

• QIf it disappeared tomorrow, how much would customers miss it? Is its growth model sustainable, without relying on harming society or on skirting regulation?5/10

  A

  Conclusion first: if Jabil disappeared tomorrow, its customers would be "inconvenienced" but would not "irreplaceably miss it" — recertifying and switching complex projects would take years and several billion dollars, but established peers such as Flex, Celestica, Sanmina, and Plexus are on the field and ready to step in; meanwhile its growth model is clean and sustainable, not dependent on harming society or crossing regulatory lines. Indispensability is "moderate," while social/regulatory sustainability is "good" — Jabil's weak point on this question is the first half (not indispensable enough), not the second half.

  Start with "how much would customers miss it" — that is, indispensability. This needs to be looked at on two levels, and the report offers evidence on both sides:

  • At the short-term, complex-project level: fairly missed. In complex or regulated segments such as medical devices, automotive, and cloud data center power/thermal/rack systems, validation, switching, and recertification costs are high (the report rates switching costs as "moderate"). The report points out that replicating Jabil's global footprint plus customer validation, supply-chain coordination, industry certifications, and multi-region quality systems typically requires years and several billion dollars of investment. So if a customer really wanted to pull an order away from Jabil, it would have to endure a not-short bout of pain — this constitutes real but limited indispensability.
  • At the medium-to-long-term, industry level: not that missed. The key is that alternatives are already on the field. Jabil itself lists its peer group as Celestica, Flex, Hon Hai, Plexus, and Sanmina, and the report judges that "the moat is hard to replicate but contestable, not insurmountable." One strong piece of counter-evidence: in the same AI pie, Celestica has already raised its 2026 guidance to $19 billion in revenue with an 8.0% adjusted operating margin, showing customers do have strong alternative suppliers. Even more telling is that the bargaining leverage runs the other way — the report notes Jabil serves stronger, larger customers: the top five customers accounted for about 36% of revenue in FY2025, rising to about 38% in the first half of FY2026, with one anonymous customer alone accounting for 16%. It is Jabil that cannot afford to lose these large customers, not the other way around. It lacks the kind of Baillie Gifford-style indispensability where "the whole world would hurt if it disappeared tomorrow."

  Now the other half of the question — whether the growth model is sustainable and does not depend on harming society or regulation. On this front, Jabil performs well:

  • The business itself is legitimate and net-positive for society. Jabil makes medical devices, automotive electronics, renewable-energy infrastructure, and AI/cloud data center hardware — these are the foundations of the real economy and technology upgrades, not businesses that profit from addiction, deception, or negative externalities. Growth comes from a ramp in AI infrastructure orders, which is legitimate demand expansion.
  • Regulatory exposure is ordinary operating risk, not "crossing red lines for growth." The report discloses that outsourced revenue accounted for about 75% in FY2025 and about 72.7% in the first half of FY2026, exposing it to tariffs, currency, and geopolitics; in regulated manufacturing segments (medical, automotive), the company must instead meet stricter quality and certification systems. These are compliance costs it must bear, not profits earned by evading regulation. On governance, the report notes incentive metrics incorporate cash flow and per-share growth, and the clawback policy was updated in 2023 — a shareholder-friendly framework. The only "soft" item that needs ongoing watching is accounting treatment — the company makes heavy use of receivables sales/securitization (booked in operating cash flow), but the report judges this to be working-capital optimization rather than concealing problems — a discount to cash-flow quality rather than a compliance issue.

  So the honest answer: if Jabil disappeared, customers would genuinely hurt for a while due to recertifying complex projects, but they would not irreplaceably miss it — homogeneous top-tier peers can step in at any time, and bargaining power sits with the customer. Its growth model is clean, legitimate, and does not rely on harming society or regulatory arbitrage; sustainability is not an issue. Baillie Gifford's verdict would be: it clears the social/regulatory bar, but what really keeps it short of "great" is insufficient indispensability — an excellent but replaceable critical supplier.

• QWhat are this business's unit economics (gross margin, incremental returns) like? Do they get better or worse as scale increases? Where does the money it earns go?3/10

  A

  Conclusion first: Jabil's unit economics are a classic case of "thin gross margin, high turnover, cash earned through execution" — gross margin has long sat at just 8%–9%, core/segment margins at 5%–5.7%, and unit economics only get "slightly better," not fundamentally different, as scale increases (an industry ceiling caps it); the money it earns goes overwhelmingly to buybacks, then bolt-on acquisitions, with dividends being minimal. This is a well-run business with low-quality economic characteristics, and Baillie Gifford would give it a mid-to-low score on the "unit economics" dimension.

  Start by laying out the profit structure clearly. The report and the financials consistently point to "thin": full-year FY2025 net revenue of about $29.8 billion and net income of about $657 million, with gross margin long stuck at 8%–9% and segment income margin at about 5.4%. The latest guidance does not break out of that band either — full-year FY2026 core operating margin guidance of 5.7% and core EPS of $12.25. The report puts it in one line: margins like these are "enough to show operations are decent, but also enough to show it lacks strong pricing power." As a comparison, peer Celestica's adjusted operating margin has already reached 8.0% — within the same track, Jabil's unit economics are not leading.

  Now look at "incremental returns" and whether things get better or worse as scale increases — this is the bullseye of Baillie Gifford's question. Jabil's answer is "scaling up brings mild improvement, but there is a structural ceiling":

  • The improvement is real. As the revenue mix shifts toward Intelligent Infrastructure (AI/cloud infrastructure, power, liquid cooling, racks, system integration), product complexity is higher and margins are slightly better. The report notes the II segment's revenue was up 53% year over year in the first half of FY2026, and up 52% year over year in Q2 FY2026, already accounting for about 49% of total revenue, and the company's full-year core operating margin guidance has also been lifted from a historical 5.4% to 5.7%. This shows incremental revenue carries a slightly higher marginal margin than the existing base.
  • But the extent of improvement is capped. The report emphasizes that higher margins in the past "came more from product/customer mix improvement and execution optimization than from a structural monopoly advantage"; and the larger the scale and the more it accelerates into AI/cloud, the more working-capital swings get amplified too — the report discloses the company acknowledges that receivables, inventory, and prepayments all rose in the first half of FY2026 (to support Q3 sales and the timing of customer-controlled consignment purchasing). So "scale leads to better unit economics" for Jabil means "a little better," not the kind of software/payments-style leverage where "the bigger it gets, the more it earns, with marginal margins soaring."

  "Where does the money it earns go" — this is the brightest spot in Jabil's unit-economics story. It puts the cash generated from thin margins and high turnover mostly into buybacks: the report notes buybacks of about $487 million / $2.404 billion / $1.030 billion in FY2023–FY2025, with dividends of only $30–45 million. The effect is real, dollars-on-the-table per-share value — shares outstanding fell from about 136 million at the end of FY2023 to about 107 million at the end of FY2025 (about a 20.7% reduction over two years). The remaining cash goes to bolt-on acquisitions (Hanley Energy and Rebound in the first half of 2026) and necessary capex. Worth noting, FY2025 free cash flow was about $1.2 billion, up about 25.8% year over year thanks to a sharp pullback in capex, and FY2026 guidance still calls for above $1.3 billion — the cash-generation capability is real, and it does not need "more money spent the more it grows."

  But the quality of the unit economics needs an honest discount. The report repeatedly warns that Jabil's high cash conversion rests partly on large-scale receivables sales/securitization programs (FY2025 sold $11.4 billion in receivables, and the first half of FY2026 sold another $8.5 billion plus $2.1 billion securitized, all booked in operating cash flow). The conclusion is not "there's a problem," but that "the cash flow is good, just not the kind of good that needs no discount at all."

  So the honest answer: unit economics equal thin gross margin (8%–9%), thin operating margin (5%–5.7%), high turnover, and profit converted efficiently into cash through execution and working-capital management; getting bigger makes it slightly better, but capped, not fundamentally different. The money earned goes mainly to buybacks (genuinely lifting per-share value), then bolt-on acquisitions, with dividends being minimal. This is an efficient "cash-conversion machine," but not a high-incremental-return "compounding machine" — this is precisely the economic root cause why Baillie Gifford would put it on the watch list rather than treat it as a core ten-year-five-bagger candidate.

• QWhat conditions would all need to hold for it to rise fivefold in ten years? Are these conditions realistic? What expectations does today's stock price already imply?2/10

  A

  Conclusion first: for Jabil to rise fivefold in ten years (about 17% annualized), four conditions would need to hold at once — for a thin-margin manufacturing services provider, that is "optimism stacked on optimism," and it is not realistic; today's stock price of about $364 already prices in an optimistic view that the AI infrastructure boom will remain strong for the long haul, leaving a negative margin of safety. The honest answer here is: Jabil does not clear the ten-year-five-bagger bar, and today's price is not a discounted way to buy the future — it is a prepayment for good news that has already arrived.

  First, calibrate the starting price. The $380.25 figure used when the report went to print was the all-time high on 2026-05-26; on a more updated basis, JBL closed at about $363.95 on 2026-06-10, with a market cap of about $40.7 billion. A fivefold gain in ten years means market cap reaching about $200 billion, or about $1,820 per share (about 17.5% annualized). For comparison: FY2026 guidance calls for revenue of $34 billion, core EPS of $12.25, and core operating margin of 5.7% — getting from this base to a five-bagger requires the product of profit and valuation to increase fivefold.

  Conditions that must all hold at once (none can be missing):

  1. Revenue sustains high growth for ten straight years. Intelligent Infrastructure would need to hold its current pace for years without retreating — the segment was up 52% year over year in Q2 FY2026, already about 49% of total revenue. But AI infrastructure capex is a cyclical, exogenous variable, and assuming it "never normalizes for ten years" is a strong assumption.
  2. Structural margin expansion. The 5.7% core operating margin would need to keep climbing, otherwise revenue growth alone cannot support a fivefold market cap. But the report repeatedly demonstrates Jabil lacks strong pricing power (tariffs can only be partly passed through) and margins are capped by an industry ceiling — peer Celestica has already reached an 8.0% adjusted operating margin, showing upside exists but is limited.
  3. The valuation multiple does not compress. Against FY2025 GAAP net income of about $657 million and a market cap of about $40.7 billion, trailing P/E is already as high as about 60x (the report's TTM basis puts it at about 51x, both pointing to extremely expensive); the forward core P/E is about 30x (364 / 12.25). A five-bagger requires the market to keep granting this kind of high multiple to a thin-margin contract manufacturer for the long run — that runs against the pull of "reverting to manufacturing-industry norms." The report says it plainly: the most fragile assumption in the valuation is "high growth persisting for years with no material multiple compression."
  4. Buyback discipline stays effective and customers do not squeeze pricing. The report lists these two as "key assumptions" — large customers do not meaningfully press for lower prices or reallocate outsourcing, and capital allocation continues to be oriented toward per-share intrinsic value. But the top five customers' share has already risen from 36% to 38%, and the bargaining scale tilts toward the customer.

  Requiring these four conditions to hold "at once" stacks every optimistic assumption together, and the realistic probability is very low. The report's DCF confirms this too: even in the optimistic scenario (Owner Earnings starting at $1.4–1.45 billion, ten-year growth of 7%–8%, discount rate of 8%–8.5%), the upper bound of per-share intrinsic value only reaches $300–360 — the current price is already near or slightly above that optimistic upper bound. What a ten-year five-bagger requires far exceeds what the report's optimistic scenario can support.

  What does today's stock price already imply? The clearest way to see it is through an owner-earnings lens: the report estimates a conservative Owner Earnings midpoint of about $1.25 billion, meaning at the current market cap you are paying about 32–34x conservative Owner Earnings; the implied equity Owner Earnings yield is only about 3.0%–3.6%, which is actually lower than the roughly 4.5% risk-free yield on 10-year Treasuries. In other words, the market has already fully priced in the "AI infrastructure winner" story — buying in today means first accepting that "this thin-margin manufacturer deserves a software/payments-level multiple," and then hoping years of future high growth will close this negative spread of more than one percentage point. The report puts it bluntly: for a thin-margin manufacturer, the current price is "not a margin of safety, but a prepayment on execution."

  So the honest answer: a ten-year five-bagger requires ten years of high revenue growth, structural margin expansion, no multiple compression, and no customer price pressure to hold simultaneously — that is optimism stacked on optimism, and it is not realistic. Today's price of about $364 already implies an optimistic view that AI infrastructure demand stays strong for the long haul, and the Owner Earnings yield even trails the risk-free rate. Baillie Gifford's judgment matches the report's: this is a "good company, bad price" situation — worth a spot on the watch list, but the current price does not provide the cushion needed for a ten-year five-bagger.

• QWhy hasn't the market realized all of this yet? Is it a failure to understand, a failure to respect, or a failure to see far enough? What would become the "narrative inflection point"?2/10

  A

  Conclusion first: on Jabil, the market has actually "not gotten it wrong" — it long ago understood, embraced, and fully priced in the AI infrastructure winner story, so the question is not "the market hasn't realized it yet" but "the market may have priced it too high." The real perception gap is not "undervaluation being overlooked," but two things that have not been sufficiently discussed: first, the discount that should be applied to earnings quality; second, the cyclicality of this current boom. The narrative inflection point will arrive the moment AI infrastructure capex shifts from "surge" to "normalization," or the moment margins prove unable to hold up.

  First, correct the premise of this question. Baillie Gifford's question usually targets "undervalued good companies the market fails to understand, respect, or see far enough for"; but Jabil is the opposite — it is a name the market already sees clearly, and even chases. The evidence is hard: over the past five years, Jabil's stock rose from a base of 100 to about 612, sharply outperforming the S&P 500's roughly 199 and the peer group's roughly 396; the current trailing P/E is already as high as about 50–60x (depending on whether TTM or FY2025 GAAP net income is used), and the forward core P/E is about 30x. My judgment matches the report's: "a lot of good news is already reflected in the stock price." So the honest answer is — the market does not fail to understand this stock; it has already given it a very full valuation.

  So where is the real perception gap (what the market may have "missed")? There are two points, and both skew negative:

  1. Cash-flow quality is being taken as a perfect score by default. The market prices Jabil's strong cash flow at face value, but the report repeatedly warns that high cash conversion rests partly on large-scale receivables sales/securitization (FY2025 sold $11.4 billion in receivables, and the first half of FY2026 sold another $8.5 billion plus $2.1 billion securitized, all booked in operating cash flow). This is not a red flag, but it means free cash flow quality deserves some discount — a discount the current valuation does not reflect.
  2. Cyclicality is being mistaken for growth. The market is valuing a thin-margin contract manufacturer with strong customers and just a 5.7% margin using an "AI platform" growth framework, while underestimating the cyclical nature of AI infrastructure capex. The report points out that the most fragile assumption is "high growth persisting for years with no multiple compression."

  Interestingly, even sell-side analysts are not as optimistic as Jabil's stock price — this itself is a piece of evidence that "market pricing is running ahead of fundamentals." The consensus median price target from multiple institutions sits at about $264–271, clearly below the current stock price of about $364; the report's optimistic DCF upper bound only reaches $300–360 too. In other words, the stock price has already gotten ahead of most serious valuations — this is not "the market hasn't realized the value yet," but "the price has already overspent the expectation."

  What would become the narrative inflection point? Based on the report and the fundamentals, a few of the most realistic triggers:

  • II growth stalls / the FY2027 outlook weakens. This is the No. 1 "trigger for reassessment" the report lists. Once the current roughly +52% Intelligent Infrastructure growth falls back to normalized levels, the "AI infrastructure winner" narrative would loosen, and the high multiple would slide quickly.
  • Margins get disproven. Core/segment operating margins declining for several consecutive periods and falling below 5% would directly refute the story that "mix upgrade brings a step change in profitability."
  • Customer concentration worsens. The top five customers' share has already risen from 36% to 38%; if a single customer exceeds 20%, or large customers press for lower prices or shift orders elsewhere, that would pull the market back to a "contract manufacturer at the mercy of strong customers" framework.
  • A shift in the valuation framework itself. Even if earnings do not collapse, once the market reclassifies it from "AI platform" back to "manufacturing," the multiple would compress — the report describes the worst realistic scenario as "AI narrative cools + multiple compresses + margin declines," with the stock potentially reverting to a conservative range of $150–220 (a 40%–60% downside from the current price of about $364).

  So the honest answer: this question needs to be answered in reverse for Jabil — the market did not "fail to understand, respect, or see far enough" and miss an undervaluation; it long ago understood the stock, priced it up, and priced it fully — what is genuinely underappreciated are two negative variables: the discount owed to cash-flow quality and the cyclicality of this current boom. The narrative inflection point does not lie in an upward moment when "value gets discovered," but in a downward moment when "II growth normalizes / margins get disproven / the valuation framework switches back from AI platform to manufacturing." Baillie Gifford's conclusion matches the report's: this is a good company that is fully priced, even prepaid with optimism — worth watching, but the inflection point is more likely to point down than up.
