In-Depth Value Analysis of Besi, a Back-End Advanced Packaging Equipment Leader

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

• QHow large is its market ceiling? Is it expanding an existing pie, or creating an entirely new market?5/10

  A

  Bottom line: Besi's ceiling is a hybrid of "expanding a cyclical pie" and "positioning itself in a structurally expanding new high-value market". The real driver of its ten-year upside imagination is the latter (AI/HBM-driven hybrid bonding, TCB, 2.5D/3D), not the mediocre growth of traditional back-end packaging. The issue is that this "new high-value market" is still small in absolute size (hybrid bonding equipment is only a several-hundred-million-dollar market even in 2030), and Besi already has about 82% share in the most core die attach segment, leaving limited room for further share gains. Its ceiling therefore looks more like structural expansion with a steep slope but a modest absolute value, rather than the "from 0 to trillion" entirely new large market that LTGG prefers.

  First quantify the pie. Besi's directly addressable market is semiconductor back-end assembly/packaging equipment, and the total pool is not large: according to Yole Group estimates, the entire back-end equipment market grows from about $6.9bn in 2025 to $9.2bn in 2030, a CAGR of only about 5.8%. That is the essence of the "large-cycle industry" described in the research report: it follows semiconductor capex cycles and grows moderately. The WSTS anchor cited in the report, "2026 global semiconductors $975bn", is already outdated: in its latest forecast in early June 2026, WSTS sharply raised 2026 to about $1.51 trillion (about +90% YoY, mainly because AI/HBM demand exceeded expectations). But it is important to note that a doubling of the end semiconductor market does not mean a doubling of the back-end equipment market. Equipment is a capex subsegment, and its growth rate is far below chip sales themselves. So if we only look at "expanding an existing pie", Besi's ceiling is limited and highly cyclical.

  The real story lies in the second nature: taking position in a "quasi-new market" where low-value process steps are being pushed into high-value process steps. AI, HBM, chiplets, and CPO are moving back-end processes away from mediocre steps such as dicing and wire bonding toward high-precision, high-ASP, high-yield-barrier steps such as hybrid bonding, TCB, and advanced die placement. Yole's breakdown makes the "structural vs cyclical" divergence very clear: hybrid bonding equipment revenue is expected to rise from about $152m in 2025 to about $397m in 2030 (CAGR about 21.1%), while TCB equipment rises from about $542m to about $936m (CAGR about 11.6%). By comparison, traditional flip-chip bonders grow only about 5%, die bonders about 3.6%, and wire bonding about 3%. At the same time, advanced packaging penetration of the overall packaging market is rising from about 40% in 2020 to more than 60% in 2030, while the overall advanced packaging market is expected to grow at about 9.5% CAGR in 2024–2030 to $79.4bn. This maps directly to Besi's internal mix disclosed in the report: about 70% of equipment revenue comes from advanced packaging and about 50% of revenue is AI-related. It shows that Besi has already placed itself in the fastest-growing, highest-ASP segment, rather than the traditional segment crushed by cycles.

  But "a high ceiling" must be separated from "how much Besi can actually capture". There are three hard constraints. First, the absolute volume ceiling is low: even by 2030, hybrid bonding equipment is only about a $397m global pool, and Besi cannot take all of it (ASMPT, K&S, Applied Materials, and others are all competing). This does not strictly match the "huge, exclusive new market" required by LTGG's search for "great growth stocks that can fivefold over the next decade". Second, the richest segment is already near saturation: the report discloses that Besi's 2024 die attach share is already about 82% and advanced die placement about 50%. That means growth must rely more on "market expansion + ASP uplift" rather than the most powerful growth lever of "share going from small to large". An 82% share has almost no room to double again. Third, customers and technology paths are concentrated: the report notes that a single customer accounted for 14.7% of 2024 revenue and the top ten customers have long accounted for more than half. Hybrid bonding is still in the "validation/adoption" stage (TCB, customer in-house development, or alternative paths may all delay HB ramp). If downstream AI capex pulls back temporarily, order elasticity will amplify in reverse.

  Management's own "ceiling" is also worth using as an upside reference, with a discount: at its 2025 Investor Day, Besi raised its long-term target from "revenue €1bn+" to revenue €1.5–1.9bn, operating margin 40–55%, gross margin 64–68%, and elevated hybrid bonding into a core pillar (management's wording implies HB could grow to about one-third of total business). Against LTM(Q1-26) revenue of about €632.1m, this means management believes the company still has 2.4–3 times volume potential. This is the most direct official answer to "how high is the ceiling", but it is a target, not reality, and it rests on two premises that have not fully materialized: "continued increase in advanced packaging penetration + large-scale HB mass production".

  Overall judgment: the ceiling is "structural expansion", not "simply large and cyclical". On this point, the report is consistent with the latest industry data. But it belongs to the type of ceiling with "a steep slope, limited absolute value, and Besi already near the top in its core submarket". From a Baillie Gifford perspective, the honest view is that Besi is positioned in a high-quality niche re-rated by AI, not an "entirely new, exclusive trillion-level market created from zero". It is more like "expanding an existing, upgrading high-value pie and defending a very high share within it", rather than opening a wholly blank new continent. That means its upside is real, but it has a clear physical ceiling. This also matches the report's core conclusion: "a good business, but at the current quote of about €283.6 (market cap about €22.5bn, Owner Earnings multiple about 128x), it already discounts many years of success."

• 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

  Bottom line: yes, and based on current sell-side consensus, the doubling will most likely be achieved around 2028. But this is a doubling highly dependent on structural hybrid bonding volume ramp, not a traditional cyclical recovery, and the upside scenario has already been fully priced by the market. Using the report's LTM(Q1-26) revenue of €632.1m as the base, doubling means reaching €1.26bn+ by around 2031. Market consensus has moved that timing sharply forward: according to Simply Wall St's aggregation of forecasts from 22/31 analysts, Besi revenue is expected to be €937m in 2026, €1,255m in 2027, and €1,527m in 2028, implying a 2026–2028 revenue CAGR of about 28%. In other words, sell-side consensus expects revenue to almost double by 2027 and reach about 2.4 times by 2028. Even after discounting this optimistic consensus, "doubling in five years" is almost a "low bar" rather than a "high bar" in this case. The real debate is not whether revenue can double, but whether doubling is enough to support the valuation at the report's cutoff price of €288.4 (latest about €283.6), which corresponds to LTM P/E ~151x.

  Why this must be stated plainly: it is the complete opposite of the 2021-2025 history. The doubling relies on structural volume ramp, not cyclical mean reversion. The report makes clear that revenue over the past five years was €749.3m→€722.9m→€578.9m→€607.5m→€591.3m, meaning zero growth over five years and even a net decline (2025 was also -2.7% YoY). Besi's revenue is highly cyclical. Looking only at the historical trend line, any "doubling" claim would be untenable. The turning point is the recent step-up in orders: 2026 Q1 orders were €269.7m, +104.5% YoY. According to the company's results commentary, the main reason was a sharp increase in hybrid bonding system orders, with 70% from foundries/subcontractors. The company guided Q2-26 revenue to rise +30%–40% QoQ and gross margin to recover to 64%–66%. This shows that the driver has shifted from "cyclical beta" to "advanced packaging penetration alpha". That is the key dividing line for whether the doubling story holds.

  Breaking down the sources of growth: "volume" is primary, "price" is secondary, and "new business" provides long-tail optionality. Among the three, volume is decisive. "Volume" is the core: according to the company's Q1-26 disclosure, single-quarter hybrid bonder unit shipment orders doubled QoQ and exceeded the prior high in 2024 Q2, the customer count expanded to 20, and TCB(TCB Next) added 2 orders with customers increasing to 6. The doubling mainly depends on system shipment volume driven by AI/HBM capacity expansion. "Price" is an amplifier, not the main engine: the ASP per tool for high-precision die attach / hybrid bonding is far higher than for mainstream equipment, and product mix upgrade will lift revenue per tool and gross margin (hence Q2 gross margin guidance recovering to 64–66%). But ASP uplift is limited and cannot independently support a doubling. "New business" provides option value: the report cites company wording that HB is expanding from HBM into logic, memory, CPO, and consumer use cases. If realized, this is key to pushing revenue toward the upper end of the company's long-term target, but the report also honestly notes that HB "adoption is still forming, not a fully mature, irreversible established reality".

  Compared with the company's long-term targets, doubling is only the "floor"; the real bet is whether it can approach the upper end. At its 2025 Investor Day, the company raised its long-term target from €1bn to revenue of €1.5–1.9bn and operating margin of 40–55% (no specific target year was given; it is a multi-year target). From the €632m base: reaching €1.26bn (doubling) implies a five-year CAGR of ~15%, reaching the lower target of €1.5bn implies about ~19%, and reaching the upper end of €1.9bn implies about ~25%. Considering that HB revenue, according to third-party estimates, rose from €36m in 2023 to 2026E ~€476m and could account for about 1/3 of company revenue, together with the high-share base of die attach ~82% and advanced die placement ~50%, revenue doubling is fairly realistic.

  My judgment: a revenue CAGR of about 15%–22% over the next five years is a reasonable midpoint range. Doubling (to €1.26bn+) is highly realistic and will likely happen before 2031. But "doubling" itself is already the market's base-case assumption and is not a source of excess return. The risk lies in the path, not the direction. If AI/HBM capex experiences a 1–2 year temporary pullback, the strong cyclicality will magnify order elasticity in reverse, pushing back the timing of the doubling or even causing revenue to fall in a particular year (as shown by 2023→2025). Therefore, to LTGG's question of "why has the market not realized this yet", the honest answer here is: the market has long realized it and has fully priced the doubling. Consensus revenue of around €1.5bn in 2028 matches the lower end of the company's target. The only remaining unpriced upside is the dual realization of "approaching the €1.9bn upper end + maintaining 40%+ operating margin". That is exactly the fragile premise repeatedly emphasized in the report, and the root of the missing margin of safety at the current ~151x valuation.

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

  A

  Bottom line: Besi does not currently have a mature second curve that is independent of the main curve and can "take over" five years from now. Its current growth engine is high-precision die attach + advanced die placement + thermo-compression bonding (TCB)/hybrid bonding driven by AI/HBM and 2.5D/3D logic packaging. Under the report's framing, about 70% of equipment revenue comes from advanced packaging and about 50% of revenue is AI-related, 2026 Q1 orders were +104.5% YoY in absolute terms at €269.7m, and hybrid bonder unit orders doubled QoQ and exceeded the previous 2024 Q2 peak. The several "second curves" often discussed by the market, HB expanding from HBM to logic/CPO/consumer, panel-level packaging, and chiplet heterogeneous integration adoption, mostly break down into vertical extensions of the same AI main curve (the same tools, the same processes, more end-use cases), rather than a new profit pool that can independently carry growth after the main curve peaks. Few candidates truly meet the definition of "taking over after five years" and still sit at the slide/validation stage today. They are assessed one by one below.

  Candidate 1: HB expanding into logic/CPO/consumer. This has partly shown up in orders, but it is an extension of the main curve, not a new engine. Logic is the most tangible today: the CEO explicitly said the company had received "follow-on orders for logic applications from a leading Asian foundry", total HB customers increased to 20, and Q1 orders were especially strong in hybrid bonding, mobile, and photonics. The logic chain for CPO/co-packaged optics is real: NVIDIA's silicon photonic switches use TSMC SoIC 3D hybrid bonding for optical engine integration, and HB is the key process for achieving the required interconnect density. But scale matters: the entire CPO market is only about $165 million in 2026 and about $760 million by 2031. For a company with LTM revenue of €632.1m, CPO over the next five years is more like "a highlight inside the order book" than an engine that can independently replace the AI main curve. Honest conclusion: logic/photonics are real incremental demand, but they are essentially a horizontal spread of the main curve (AI advanced packaging), and they do not take Besi into a new demand pool unrelated to AI capex.

  Candidate 2: HB entering HBM memory mass production. This is the "second leg" the market most hopes for, but today it is clearly still in validation/adoption, and the timing has been pushed out. The key honest point is this: after the HBM4 standard was relaxed, it continued using microbump and postponed hybrid bonding adoption. The CEO himself also acknowledged that "with the relaxation of the HBM4 standard, hybrid bonder adoption has been delayed". The true status on the memory side is "testing", not "mass production": three memory manufacturers are testing HBM hybrid stacking (a second memory customer received 2 evaluation tools, plus repeat orders from an existing memory customer). Besi places full HB ramp hopes on HBM4E 16-high stacks (first targets in 2026) and HBM5 (envisioned as "all hybrid bonding"), while the industry generally points to 2028 for large-scale HB memory mass production, consistent with the report's statement that "new AI device introductions are concentrated in 2027–2030". In other words: memory HB could indeed become an important incremental driver five years from now, but today it consists of scattered evaluation-tool orders, not a revenue center. The report lists "HB ramp below expectations" as the biggest risk precisely because this most imaginative leg has not yet been secured.

  Candidate 3: panel-level/wafer-level packaging and broader chiplet heterogeneous integration. These are closer to industry-level long-term trends; for Besi, they are natural benefits to the main curve rather than a proprietary new engine. The adoption of chiplet/2.5D/3D heterogeneous integration is indeed the fundamental driver of die attach and advanced die placement demand, but it is the same business already served by Besi's 82% die attach and ~50% advanced die placement share, so it lacks the independence of a "second curve". More frontier directions such as panel-level packaging and glass substrates remain earlier-stage: glass interposers are still at TRL 4–5, moving from R&D toward production-line transition, and they belong to the substrate/interposer layer rather than Besi's die-bonding core field, making capture by Besi within five years hard to assert. Besi's own wafer-level footprint (Malaysia expansion, Vietnam releasing mainstream capacity) is more about supporting throughput of the existing main curve than building a new business from scratch.

  Final answer from a Baillie Gifford perspective (pragmatic, without overstating): measured by LTGG's yardstick of "does the second curve already exist today", Besi's answer is leaning negative. It does not have a mature new curve decoupled from the main engine that can independently sustain growth after an AI capex ebb. What it has is one main curve (AI advanced packaging HB) deepening vertically across logic→photonics→memory use cases, with logic/photonics already showing up in orders and memory mass production still in validation with timing pushed out to 2027–2030. This is both Besi's strength (deep process positioning and several years of use-case tailwinds on the main curve) and the reason it does not fit the classic "fivefold growth stock" template: growth is highly tied to a single technology route + a single capex cycle, with no second growth pole to hedge the risk. At the 2026-06-03 cutoff price of €288.4 (closed around €283.6 on 2026-06-04, report basis LTM P/E ~151x), the market has prepaid for the "most successful future version". The report's conclusion of "good business, bad price, Watch, ideal buy €60–90" is internally consistent with the judgment that "the second curve has not yet been secured". The true inflection signal worth tracking is the moment memory HB moves from evaluation to scaled mass-production orders, not another use case added to a slide.

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

  A

  Bottom line: Besi's moat is real, but it is not a "brand" moat. It is an industrial moat built from process precision + customer validation cycles + switching costs + niche scale + through-cycle cost advantage. My core judgment is that over the next three to five years, this moat can mostly only move sideways or narrow slightly in the existing base business (die attach), while it has a chance to widen in the incremental new battlefield (hybrid bonding). At present, however, it is closer to "leading position" than "locked victory". The durability of the lead is only moderately strong, far from irreversible. Combining the two lines, this is a "high-quality moat whose profit distribution is being repriced by larger players", not a moat that is still naturally widening.

  Start with the real sources of the moat. It is not a consumer brand; it consists of four parts. First, process precision and yield barriers: die attach, advanced die placement, TCB, and hybrid bonding all require sub-micron-level (HB requires <10nm-level precision) placement accuracy and very high yield control. This is know-how and engineering accumulation, not a single patent. Second, switching costs: the report states this well. For customers, changing equipment is not just changing a machine; it means restarting process qualification, production-line takt matching, yield ramp, and end-customer audits, usually measured in years. Third, niche scale: in 2024, die attach share was about 82% and advanced die placement about 50%, bringing a larger installed base, higher R&D amortization efficiency, and a deeper process database. Fourth, the through-cycle cost advantage of "European R&D + Asian manufacturing": in the 2023 industry downturn, it still held a 64.9% gross margin, 30.6% net margin, and €208.6m operating cash flow, proving it does not rely only on cycle strength. The combination of these four parts is the foundation that makes Besi worthy of being called a leader. I agree with the report's 4/5 score.

  Why the moat in the existing base business is hard to widen further and may narrow slightly. An 82% die attach share is a double-edged sword: it proves the depth of the barrier, but it also means room for further share gains is nearly exhausted. This line will depend more on downstream capex cycle volume than share expansion, and the "width" of the moat has already touched the ceiling. Meanwhile, the real threat identified by the report is materializing: the most dangerous thing is not small players copying it, but large players committing resources to change profit distribution. Applied Materials' 2025 purchase of a 9% stake based on four years of HB collaboration is an endorsement. But Reuters reported in March 2026 that Besi had been approached by Lam Research and Applied Materials for an acquisition and hired Morgan Stanley to evaluate it; the stock jumped 10% to a record high in one day. This shows precisely that when die attach/HB becomes a strategic scarce asset in the eyes of front-end giants, the "ownership" of the moat itself may change hands. For an independent small-cap leader, this is the most direct signal of "being absorbed by larger players and having profits repriced", not natural widening.

  Why the lead in the incremental new battlefield (hybrid bonding) is "not secure enough". This is the section that most requires online verification and most affects the judgment. First, the prize in the new battlefield has not really been paid out: the current HBM4 mainstream route is still TCB rather than HB, and SK Hynix's HBM4 uses about 50 TC bonders, nearly half of them awarded to ASMPT. The industry generally expects HB scale-up after HBM4E / 2H2026, and Hanmi has even publicly stated that "TC bonders are sufficient for HBM4 and HBM5". In other words, Besi's "lead" in HB currently shows more in precision reputation and prototype/adoption milestones than in a locked pool of large-scale mass-production orders. Second, competitors are fighting for orders with real money: ASMPT, through its FIREBIRD/LITHOBOLT platforms, has won large chip-to-substrate TCB orders of 19 tools + 15 tools, and has targeted a TCB TAM above $1bn in 2027 with 35–40% share for itself. K&S is also being pulled into TCB by AI/HBM4 demand. ASM/K&S/Besi together account for about 50% of the TCB bonder market. That means Besi is not dominant alone in the adjacent TCB bridgehead, and competitors can use TCB relationships to enter HB at any time. Third, customer in-house development is a real risk: Samsung/SEMES is already building its own HB tools, and SK Hynix/Hanwha are increasing HB R&D. HBM customers are highly concentrated and all have incentives to internalize equipment, which will erode Besi's capturable future HB share from the demand side.

  Net judgment on widening vs narrowing. Positive factors: if HB ramps in HBM4E/HBM5 and logic-chip 3D stacking, Besi's precision positioning + AMAT industry linkage + process data and switching costs deepened year by year through mass production will make this new moat increasingly real. That is the upside option under the LTGG lens where "the market may not have fully realized it". Negative factors: die attach share is capped, the HB battlefield has fierce competitors and delayed payoff, customer in-house development is a risk, and the structural risk of "being acquired by a large player and having profits repriced" exists at the same time. Overall, I do not think this is a moat that is certainly widening: the existing base moves sideways and slightly narrows, while the incremental battlefield is "leading but not locked". Honestly, describing Besi's moat trend as "one-way widening" would overstate the growth narrative. A more factual expression is: the moat is deep but no longer widening; HB is the only variable that could widen it again, and over the next three to five years that variable is still a "probability", not a "fact". This is also the fundamental reason the report gives a "Watch (good business, bad price)" rating, places the ideal buy range at €60–90, and flags the current price of about €283.6, market cap about €22.85bn, P/E about 152x: the moat quality supports a premium, but not a current price that has already prepaid the full-victory HB outcome.

• QIf its core business is disrupted, does it have the DNA to reinvent itself? How does it deal with mistakes and bad news?5/10

  A

  Bottom line: Besi's "reinvention DNA" has been genuinely validated by history. It is not an equipment company that only defends existing products; over three decades, through a series of acquisitions and bets, it transformed itself from traditional back-end packaging all the way to the frontier of hybrid bonding. Management's communication on cyclical downturns and bad news is also mostly candid and direct, with little glossing over. But this "ability to reinvent" has boundaries: it rests on a single main business line, a single technology-route bet, and the personal judgment of a CEO who has been at the helm for 30 years. If future disruption comes from directions it is not good at (such as customer in-house equipment, or competitors overtaking it in HB), its room to turn is narrower than that of integrated equipment companies. The report therefore scores management and capital allocation at 4/5, with the key deductions being "key-person risk" and concentrated bets.

  Positive evidence: it has indeed "reinvented" itself more than once, and proactively. Besi was founded by Richard Blickman in 1995, emerging from the packaging equipment businesses of Philips Semiconductor and ASM. Its initial products were traditional back-end tools such as die sorting, molding, and plating, which competed on reliability and cost. It did not stop there: in 2005 it acquired Austria's Datacon for €72.6m to enter flip-chip and multi-chip die bonding, and in 2009 it acquired ESEC's die bonding business from Oerlikon to strengthen advanced packaging, gradually moving into thermo-compression bonding (TCB) and then into hybrid bonding in the early 2020s. The report summarizes this main line clearly: the die attach, wafer/substrate-level assembly, TCB, and hybrid bonding that truly drive today's valuation are the result of the company's "successful transformation", not a mediocre continuation of traditional packaging. Combined with the financial commitment, gross R&D rose from €41.5m in 2020 to €87.7m in 2025, and from 9.6% to 14.8% of revenue. That supports the judgment that reinvention is not a slogan; it has been paid for with real money and continuous acquisition of new process capabilities. Blickman predicted years ago that "More than Moore" would push the back end toward front-end-level precision. This behavior pattern of "betting on the next wave while the old business is still profitable" is itself the adaptive DNA that LTGG values.

  It is also institutionalizing preparation for "the next disruption", instead of relying only on one person's intuition. During the 2023 downturn, the company specifically formed a Technology Advisory Board, with external members from former executives at TSMC, ASML, Applied Materials, and other companies, to "advance core technologies, competitive position, and growth prospects". This externalizes frontier-technology sensing and reduces single-point judgment risk. Together with Applied Materials' 2025 purchase of a 9% stake and its emphasis that the stake was based on the two companies' "four-year hybrid bonding collaboration", it shows that Besi is not betting on one path alone; it has embedded itself in the technology network of leading industry players. That lowers the probability of "digging deeper on the wrong technology route".

  Negatives and risks: its room for reinvention is narrower than that of integrated equipment companies and is highly dependent on one person. This fragile leg must be stated honestly. First, single main line: the report repeatedly emphasizes that Besi essentially has "only one main business line", unlike AMAT or ASMPT, which have multiple product lines that can support one another. If the packaging technology route truly shifts to a solution where Besi is weak, or if major customers choose in-house equipment, it does not have "another leg" to switch to; transformation would require rebuilding from the foundation of equipment capability. Second, concentrated bet: hybrid bonding is the core of the current story, and the report explicitly notes that the technology is "still in gradual adoption". If TCB or customer alternative solutions delay HB ramp, the bet will be impaired. This is fundamentally different from a conglomerate's fault-tolerant structure where one side can work when another does not. Third, key-person risk: Blickman has been in charge since 1995, and the strong strategic continuity is an advantage, but the report treats it as a clear deduction. If reinvention capability is overly tied to the judgment and authority of a long-tenured CEO, a succession gap directly weakens the credibility of "the next reinvention". This is also one of the key reasons the report gives management 4/5 rather than full marks.

  Second layer, "how it deals with mistakes and bad news": mainly candid and direct, with little sign of glossing over. Based on verifiable management communications, Besi's language during cyclical downturns has been quite direct. When 2023 revenue fell 19.9% YoY, Blickman stated plainly in the results release that "revenue and order weakness reflected a significant decline in demand from IDMs and Asian subcontractors for mainstream computing applications", compared the downturn to the cycle "as severe as 2017–2019", and described the 2024 recovery cautiously as having "uncertain recovery slope, limited mainstream application demand, and weak automotive end demand" in its commentary. It did not describe a weak market as a strong one. The same was true in 2025: when net margin fell from about 30% to 22.3% and revenue slipped to €591.3m, the company attributed it to weakness in mobile/automotive/industrial markets and the FX drag from a weaker US dollar against the euro, consistent with the report and without hiding margin decline inside a glossy narrative. The report's financial-quality section also independently confirms this "no glossing over" trait: management truthfully disclosed in annual reports that buybacks are "mainly used to offset dilution from convertible bonds and employee incentives, without substantially reducing the share count", rather than packaging them as "continuous repurchases increasing per-share value". One caveat for investors to weigh: honesty about past bad news does not mean future optimism will necessarily materialize. The long-term targets of revenue €1.5–1.9bn and operating margin 40–55% in management's roadshow materials are still quite optimistic long-term aspirations. The gap between "looks good on a slide" and "ultimately realized" is exactly why the report keeps a "Watch" rating on valuation. Management is candid about bad news that has already happened, but that does not make future optimism certain.

  Overall judgment (Baillie Gifford perspective, without overstating): Besi is one of the few companies that can show a real historical record on "reinvention DNA". It has transformed, integrated acquisitions, and built institutional buffers for the next technology wave through external advisors and industry alliances. Management also faces bad news directly. This is important support for calling it a "high-quality leader". But we must honestly acknowledge that this reinvention capability is "single-threaded", lacks the multi-leg fault tolerance of integrated equipment companies, and is highly tied to one person. Add the report's repeated emphasis on "good business, bad price" (current €283.6 corresponding to P/E of about 149x), and even strong reinvention DNA cannot substitute for a purchase price with margin of safety. This dimension deserves a neutral-to-positive assessment, but it is not a reason to chase at the current price.

• QDoes management (especially the founder) have a long-term view and deep alignment with the company? Is it willing to sacrifice current profits for five to ten years out?5/10

  A

  Bottom line: Blickman is an owner-operator archetype with an ultra-long tenure and real but limited proportional alignment. The incentive structure and R&D discipline do lean long-term. But if we strictly apply Baillie Gifford's yardstick of "willingness to sacrifice current profits for 5–10 years out and reinvest all cash", Besi is actually a counterexample. It returns about nine-tenths of profit to shareholders through dividends + buybacks rather than committing everything to reinvestment. This is capital allocation in the style of a "high-quality cash cow", creating structural tension with LTGG's preferred founder profile of "sacrificing the present for the long term". Overall: strong long-term perspective, above-average alignment, but weak evidence of "sacrificing current profit for the long term".

  Long-term view and tenure: very strong, but with key-man risk. Richard W. Blickman founded the company in 1995 and has served as CEO and chairman of the management board ever since, for more than 30 years (macroaxis data is consistent with company disclosures). Based on his education history, he is now close to 70 years old. Remaining at the front line across multiple semiconductor cycles gives the company very strong continuity in strategy and capital allocation, which is exactly the "thinking in decades" base that Baillie Gifford values. The report also treats "strategic continuity" as a positive. The other side of the coin is the key-person risk repeatedly highlighted in the report: management is overly concentrated in one long-tenured founder, while second-line transparency is low. Public materials reveal little about a clear succession arrangement or designated successor, and searches on governance and succession show no mature succession plan disclosed by the company. For a framework betting on "years 3–10", this is a governance question that cannot be ignored.

  Alignment: directionally right, above-average in scale, but not a "controlling founder". Blickman directly holds about 1.7% of the shares and is the company's largest insider, worth about €141m at the disclosure-time market cap (Simply Wall St, ownership structure). Based on the current market cap of about €22.5bn, the value of his stake is significantly higher. This is real money and enough to put the founder and outside shareholders "in the same boat". But two points must be made honestly. First, 1.7% is far from a "controlling owner-operator" stake. The company is effectively institution-led (institutions ~64%, BlackRock about 10%, FMR about 6.1%, Vanguard about 3.8%) and has no defensive control structure such as a STAK/foundation. In governance terms, it is a "widely held + deeply involved founder" company, not a founder-controlled family company. Second, compensation is already aggressive: 2024 CEO total compensation was about €17m (+86% YoY), with base salary only about €700k and more than nine-tenths from bonuses and long-term incentives (Simply Wall St compensation analysis). This is far above the Dutch peer median of about €570k and occurred against a backdrop where EPS declined about 15% annualized over three years, weakening the quality of "pay-for-performance".

  Incentive direction and R&D discipline are genuine long-term strengths. Besi's short-term incentives do not focus on revenue scale, but on quality metrics. The report cites the 2024 annual report: in the financial portion of STI, net margin accounts for 50%, ROE for 25%, and CFO/Revenue for 25%. This design of "not growing for growth's sake" neatly avoids the most common growth-stock trap of burning cash for scale, and is directionally consistent with Baillie Gifford's preference for "high-quality long-term compounding". R&D investment also proves that management is willing to bet for the long term: gross R&D as a share of revenue rose from 9.6% in 2020 to 14.8% in 2025 (absolute amount €41.5m→€87.7m), and Besi continued increasing spending on hybrid bonding even in 2025, when revenue slipped and margins fell. This is evidence of "investing for years 3–10".

  The tension with Baillie Gifford's "sacrificing current profit" standard must be laid out plainly. Baillie Gifford tends to prefer Amazon-like founders who willingly depress or sacrifice current profits for years to dominate future markets and reinvest every unit of cash into growth. Besi follows another path: since 2011, it has returned about €2.4bn to shareholders through dividends + buybacks (roughly equal to one-third of historical total revenue), distributed €251.3m in 2024, and proposed a 2025 dividend of €1.58/share, with a payout ratio as high as 95% (company FY2025 results release, also confirmed by the 2026-02-19 Nasdaq republication). Returning nearly nine-tenths of profit to shareholders instead of reinvesting everything means management's judgment is that this high-quality business does not need to consume all cash for growth (the report also confirms its low physical capex and high ROIC nature). Rather than piling capital inefficiently, it is better to return excess cash to shareholders. Under a Buffett framework, this is disciplined capital allocation and a positive. But under the specific Baillie Gifford question of "willingness to sacrifice current profit for the long term", the answer is closer to "unwilling, and unnecessary". Besi is not sacrificing current profit to bet on a huge future; it is compounding carefully in a proven high-return niche. This is not a flaw, but it is a fundamental mismatch with the LTGG template. Investors should not misread it as a "typical growth-founder" profile.

  Negatives and deductions: beyond the key-man risk and low second-line transparency above, the report's point that "buybacks do not equal real share-count reduction" also weakens the substance of alignment. Buybacks are mainly used to offset dilution from convertible bonds and employee incentives, and the share count has not materially declined (78.49m at end-2022→77.02m at end-2023→79.31m at end-2024→79.24m in 2026 Q1). Together with the remaining €175m 2029 convertible bond (conversion price about €115.5, early redemption announced on 2026-06-04) and €350m 2031 senior notes, the force of "per-share value enhancement" is weaker than the headline buyback amount suggests. At the current pricing of about €283.6 (2026-06-04 close, report cutoff price €288.4) and P/E near 149x, the alignment effect of the CEO's 1.7% stake is more about "sharing upside" than "expressing long-term confidence by buying at a low price". In short: as a Buffett-style example of "rational capital allocation + owner mentality", management can score highly on this question. But as a Baillie Gifford-style founder willing to sacrifice current earnings for five to ten years and reinvest aggressively, Besi's profile does not match. This dimension should provide neutral-to-weak support for the growth narrative.

• QIf it disappeared tomorrow, how much would customers miss it? Is its growth model sustainable and not dependent on harming society or regulatory arbitrage?6/10

  A

  Bottom line: (a) indispensability is very high, but not "irreplaceable". If Besi disappeared tomorrow, customers making HBM/AI chips would miss it badly. In the short term, there is indeed no ready substitute with equivalent precision, and its 2024 die attach share of about 82% and advanced die placement share of about 50% (report basis) quantify that dependence. But the moat is a "process validation + niche scale" moat, not an exclusive monopoly; competitors can gradually close the gap over several years. (b) The growth model itself is "clean": Besi sells compliant capital equipment, demand comes from real structural expansion in AI/HBM/advanced packaging, and there is no obvious social negative externality. But this growth chain is highly tied to a geopolitically sensitive semiconductor equipment chain with tightening export controls. That is its most tangible sustainability discount, not a moral-risk issue.

  (a) If it disappeared tomorrow: customers would miss it badly, but the "degree of missing it" must be separated by process segment. The key distinction is between two types of advanced bonding: die-to-wafer (D2W) hybrid bonding, where Besi is a recognized leader in precision and high-yield mass production, with its latest prototype reaching 50nm alignment accuracy; and wafer-to-wafer (W2W) hybrid bonding, which is led by EV Group (EVG), with about 82% share of the W2W market. In other words, Besi's "indispensability" is concentrated in the D2W step, the most expensive, most difficult, and closest to HBM/AI chiplet stacking. There it is close to irreplaceable, but it does not cover all bonding processes. Switching costs are real and high: the report discloses that changing equipment suppliers would trigger process requalification, production-line takt retuning, yield reramp, and end-customer reapproval. External industry materials also confirm that Besi has accumulated 150+ cumulative hybrid bonding orders, 18 customers, and deployed integrated production lines. Once customers anchor the yield of a generation of HBM/AI products on Besi's platform, switching suppliers midstream is extremely costly. Applied Materials' purchase of about a 9% stake based on four years of collaboration is itself an industry endorsement that "this company is hard to route around in the bonding process chain".

  But "miss it" does not mean "no substitute can be found". The substitute-supplier landscape is thickening, and this deduction must be stated honestly. Besi is not adjacent to a blank field: ASMPT is the largest full-line back-end competitor, is pushing second-generation hybrid bonding, and is sampling to HBM customers; Hanmi has built a strong position in TCB (especially Dual-TC for HBM), posing a material threat in the memory subsegment; K&S is expanding from its old wire bonding/die attach base into advanced interconnect; and SUSS MicroTec, ASMPT's hybrid bonding JDA with Kokusai Electric, and even reports that ASML is evaluating entry into hybrid bonding equipment are all increasing supplier density in this track. In other words, if Besi disappeared tomorrow, customers' AI/HBM capacity ramp would be seriously impaired for 1–3 years (short-term indispensability holds), but this is an industrial moat built from "high switching costs + niche scale + process lead", not structural exclusivity like a brand or network effect. The report itself scores the moat at 4/5 and explicitly notes that "the real danger is not small players copying it, but large players investing resources and changing industry profit distribution". This is especially important when placed alongside the current P/E of about 151x and market cap of about €22.5bn (2026-06-03 close about €286): the market is pricing it as if "D2W stays dominated by one player and the profit pool is not diluted", while the thickening supplier landscape is the main opposing force to that assumption.

  (b) Sustainability / society and regulation: the growth core is "clean", but it is tied to a tightening export-control chain. Start with the clean side: Besi sells compliant capital equipment. Demand comes from the real structural tailwind of AI, HBM, 2.5D/3D, and chiplets pushing packaging toward higher precision, not from gray revenue that harms society or crosses red lines. The product itself has no obvious negative externality, and Q1-26 orders growing 104.5% YoY and hybrid bonding orders jumping sharply reflect derivative demand from end compute expansion. The real sustainability constraint is regulation and geopolitics, not morality. Advanced back-end packaging sits squarely within the core reach of US export controls: in December 2024, BIS imposed China-wide controls on advanced packaging equipment, HBM, and DRAM, added multiple ECCNs (including revised 3B001), and expanded the Entity List and foreign direct product rules. New rules in February 2026 further expanded the scope of controlled semiconductor equipment and EDA and tightened de minimis. Since January 2025, more than 180 Chinese AI chip/advanced packaging/equipment entities have been added to lists, and CXMT and others have been unable to obtain US equipment since January 2025. Besi's manufacturing and customer focus are both in Asia.

  Therefore, the overall ruling on Question 7: Besi passes the indispensability test with a high score (customers cannot do without it in the short term, switching costs are high, and D2W process leadership is real), while the sustainability test deserves only a balanced assessment of "real structural demand, but tied to geopolitical risk". Besi itself specifically discussed the impact of new tariffs, trade restrictions, and export-rule changes on demand, costs, and supply-chain complexity in its Q1-26 release, and the report also lists "supply chain, geopolitics, FX, and regulation" as an independent risk item. Its growth is not "dirty growth gained by harming society", but it is also not the type of "pure structural volume ramp with no political friction" that LTGG most prefers. Customer concentration further increases this fragility: in 2024, a single customer accounted for 14.7% of revenue and the top ten about 52%. Together with export controls that impose a "demand-side ceiling" on some end markets (especially China advanced packaging/HBM capacity), Besi's sustainable growth depends more on the capex cadence of customers inside control-approved regions such as the US, Korea, and Taiwan. In one sentence: if Besi disappeared tomorrow, customers would miss it badly, and the missing would be a real "process bottleneck" kind of missing; but that indispensability sits on a sensitive chain where export controls keep tightening and profit distribution may be reshaped by large players. It still deserves a real discount before one can say it is "clean enough to hold blindly for the long term". This is consistent with the report's overall judgment of "Watch (good business, bad price)" and ideal buy range of €60–90.

• QWhat are the unit economics of this business (gross margin, incremental returns)? Does it get better or worse as it scales? Where does the money it earns go?7/10

  A

  Bottom line: Besi's unit economics sit in the rare "high-quality" tier of the semiconductor equipment industry. Gross margin has stayed above 60% through the cycle, incremental returns are very high, and capital intensity is extremely light. But scale effects are not a flawless linear leverage machine; operating margin and net margin have shown a clear downward trend in recent years. Returning most cash to shareholders at a 95% payout ratio (rather than reinvesting rapidly) internally confirms that management itself runs the business more as a "high-quality cash cow" than a "high-speed reinvestment compounding machine". That creates tension with the Baillie Gifford template of "fivefold in the next decade".

  ① Unit economics: a textbook high-quality business. Gross margin in 2021-2025 was 59.6%→61.3%→64.9%→65.2%→63.3%, and even in the 2023 industry downturn it held at 64.9%, staying above 60% through the cycle. That is first-tier in the equipment industry. More importantly, capital intensity is extremely light: capex was only €12.0m in 2024, €15.8m in 2025, and just €1.08m in 2026 Q1 (about 0.6% of revenue). Full-cycle capex is only 2-3% of revenue. Growth depends on R&D and process validation (2025 R&D €87.7m, 14.8% of revenue), not heavy physical factories, so operating cash flow is usually higher than net profit: 2023 operating cash flow €208.6m＞net profit €177.1m, 2024 €201.1m＞€182.0m, 2025 €178.1m＞€131.6m. This means earnings are real cash earnings, and incremental revenue requires almost no proportional capital tied up, so incremental return on invested capital is high. On "unit economics themselves", this is indeed an excellent business.

  ② Direction of scale effects: positive operating leverage is real, but "more growth means more profitability" needs a discount. In an upcycle, leverage is very powerful: Besi's official Q1-26 release showed revenue of €184.9m, +28.3% YoY, operating profit of €63.9m (+62.6%), net profit of €51.6m (+63.8% YoY), operating cash flow of €93.0m, and net margin recovering to 27.9%. Management explicitly attributed the profit improvement to "revenue growth, cost discipline, and the benefit of operating leverage". But that is a single-quarter recovery reading and cannot hide a worrying long-term curve: operating margin fell from 42.4% in 2021 to 29.3% in 2025 (42.4%→40.7%→36.9%→32.2%→29.3%), and net margin fell from 37.7% to 22.3%, mainly because of US dollar depreciation against the euro, weak mobile/automotive/industrial mix, and cycle position in 2025. In other words, scale effects are stable at the gross-margin level, but at the operating/net-profit level, FX, product mix, and cycles repeatedly erode leverage. Honest judgment: this is conditional leverage that makes the company more profitable when the cycle is rising, but it is not monotonically amplified across the cycle. It is not a flawless linear leverage machine.

  ③ Where the money goes: half is "smart money", while half is "returned to shareholders" rather than rapidly reinvested. Money mainly flows to two places. The first is R&D: gross R&D rose from €41.5m in 2020 to €87.7m in 2025, and from 9.6% to 14.8% of revenue. This is "smart money" betting on hybrid bonding/advanced die placement, and the direction is right. The second is shareholder returns: since 2011, cumulative dividends + buybacks total about €2.4bn (about one-third of historical total revenue), and 2024 distributions totaled €251.3m. The proposed 2025 dividend is €1.58/share, with a payout ratio as high as 95%, plus about €82.0m of buybacks and a new €60m/up to 10% of share capital buyback plan.

  There is a tension here that must be highlighted for the Baillie Gifford framework: a 95% payout ratio means Besi returns most free cash flow to shareholders instead of rolling it forward at a high reinvestment rate. LTGG's favorite "fivefold in ten years" companies usually reinvest every unit of cash back into the business and self-compound at very high internal returns. Besi's capital allocation profile is the opposite: it looks more like a mature, asset-light, high-quality cash cow that distributes excess cash. This is rational and shareholder-friendly in itself (capital is light, and there are not that many high-return reinvestment opportunities to absorb all cash), but it also objectively shows that even management's own capital allocation does not look like it is running a high-speed reinvestment growth machine. In addition, the report notes that a large portion of buybacks mainly offsets dilution from convertible bonds and employee incentives (share count was about 78.49m at end-2022, but rose to 79.31m at end-2024 and was about 79.24m in 2026 Q1), so the share count has not continued to decline materially, and the "per-share value enhancement" is not as strong as it appears.

  Overall: on the single dimension of "unit economics", this is a high-quality business, with high scores for gross margin and incremental returns. But viewed through Baillie Gifford's growth lens of "why has the market not realized it and can it fivefold over the next decade", scale leverage has marginally loosened, and the 95% payout capital profile looks closer to a mature cash cow than a high-speed reinvestment compounder. This is the micro foundation for the report's "Watch (good business, bad price, ideal buy range €60–90)" rather than "growth buy" conclusion.

• QWhat conditions must all be true for it to rise fivefold in ten years? Are those conditions realistic? What expectations are embedded in today's share price?2/10

  A

  Bottom line: a fivefold return in ten years (market cap from ~€22.5bn to ~€112bn, share price from €283.6 to ~€1,420) mathematically requires a near-perfect set of mutually independent conditions to all hold at the same time. Fundamentals must deliver close to the company's most optimistic long-term blueprint, and valuation multiples must barely fall over ten years. The report's core judgment of "good business, bad price" lands exactly on this math problem: today's €283.6 quote corresponds to LTM P/E of about 151x, a conservative Owner Earnings multiple of about 128x, and an earnings yield below 0.8%, meaning the market has already prepaid "many future years of very high growth + sustained high valuation" into the current price. Laid out plainly, a fivefold return is more of an "upside narrative" than a base-case expectation.

  Start with the hard constraint on profits. A future market cap of ~€112bn after fivefold appreciation must be supported by real earnings ten years from now. If the valuation "normalizes" to a 30–40x P/E appropriate for a high-quality semiconductor equipment stock (which is still not cheap), the company would need about €2.8–3.7bn of net profit. Besi's current LTM net profit is only about €152m, implying net profit must grow about 18–24 times over ten years. Even if we assign a still-expensive 50x multiple, it would need ~€2.2bn of net profit, about 15 times today's level. In other words, either earnings must be nearly perfect, or today's extreme 100x+ multiple must be "maintained". The latter is itself a bet, not a dependable base case. The report states this directly: the current price "almost requires you to believe that over the next 10 years, Besi will not only turn hybrid bonding into a super-large track, but the market will also sustain an extremely high valuation premium for it over the long term".

  Then look at revenue, the hardest constraint. Besi LTM revenue is only about €632m. Under AI/3D packaging demand, the company itself has raised its long-term targets to revenue of €1.5–1.9bn and operating margin of 40–55% (without giving a timeline). Even perfect delivery of the upper end of that range, €1.9bn, is only about 3 times revenue. Sell-side consensus is more restrained: 2027–2029 revenue is about €1.1–1.4bn. To turn ~3 times revenue into ~18–24 times profit, the only bridge is an extreme increase in margins and the profit pool: hybrid bonding must grow from today's "validation/adoption" stage into a super profit pool with one-player dominance and excess pricing, pushing operating margin from LTM about 31.3% all the way to the upper end of management's 40–55% target and keeping it there for a long time. This is a "possible but far from certain" script. The report explicitly notes that HB is "still expanding into logic, memory, CPO, and consumer scenarios", and adoption is still forming rather than an irreversible established fact.

  These three conditions must stack; if any one fails, the fivefold case collapses. ① Revenue races toward the €1.9bn level and the trend is not interrupted by the cycle (2025 revenue actually declined 2.7% YoY); ② margins push to the upper end of the 40–55% range rather than reverting to traditional equipment-stock levels; ③ the terminal valuation multiple basically does not collapse over ten years. They are not serial links in one chain, but more like three coins that must all land heads. The report describes this structure as "built on the simultaneous realization of multiple optimistic assumptions", and accordingly concludes that "as long as any one link deviates... returns for buyers at today's price will be severely eroded".

  What expectations are embedded in today's share price? The near-term analyst expectations make it clear: sell-side consensus for next fiscal-year EPS is about €3.68, and the following year about €5.3, corresponding to long-term EPS growth of about 28%/year and revenue growth of about 23%/year (far above the European semiconductor industry's about 9%). These are already quite optimistic numbers, yet they only support a path where "performance gradually digests the high valuation over several years", not "another valuation expansion on top to fivefold". At €283.6, a market cap of about €22.5bn, and close to the 52-week high of €291.10, with the sell-side 12-month average target price only about €252.55 (meaning consensus target price is below the current price), the price leaves almost no discount for upside surprise and instead treats "near-perfect execution" as a given.

  Honest landing point: using Baillie Gifford LTGG's "ten-year fivefold" yardstick, Besi has almost no advantage on the core question of "why has the market not realized it yet". The market has not only realized it, but has already priced the most successful future version in advance. At the current valuation, a fivefold return over ten years requires near-perfect fundamental delivery plus valuation not falling for ten years (the product of two low-probability events), or the math does not work. This is an "upside scenario", not a reasonable base-case expectation. The report accordingly gives a Watch rating, an ideal buy range of €60–90, and warns that in a multiple-compression scenario the share price could pull back by more than 50%.

  Jun 5, 2026
• QWhy has the market not realized all this yet? Is it too hard to understand, too easy to dismiss, or too far out to see? What will become the "narrative inflection point"?3/10

  A

  Bottom line: under the premise embedded in this Baillie Gifford question, that "the market has not yet realized it and there is a perception gap", Besi is almost a counterexample. It is not cheap because it is "too hard to understand" or "too easy to dismiss". It is fully understood, and may even be over-priced. At the 2026-06-04 close of €283.6, corresponding to P/E of about 149x and market cap of about €22.5bn (report cutoff price €288.4, LTM P/E about 151x, conservative Owner Earnings multiple about 128x), the share price has more than doubled over a little more than a year and is close to the 52-week high of €292.9. Together with the report's disclosure that "about 50% of revenue is AI-related and about 70% of equipment revenue comes from advanced packaging", these facts show that the market has not only seen the growth story around hybrid bonding / AI advanced packaging, but has already embedded it into the price. The honest answer is therefore not "the market does not understand, so it is cheap", but an explanation of "where the disagreement lies for something this expensive".

  The two classic perception gaps, "too hard to understand" and "too easy to dismiss", largely do not apply to Besi. "Too hard to understand" usually occurs in early companies with obscure business models and few buyers. But Besi has about 82% die attach share, Applied Materials bought a 9% stake in 2025 and publicly endorsed four years of hybrid bonding collaboration, and sell-side coverage is dense. Currently, among 22 analysts, 14 rate it Buy, 7 Hold, and 2 Sell, with the composite rating leaning "Buy". This is a thoroughly researched, institutionally watched stock, not an overlooked niche name. "Too easy to dismiss" (because it is cyclical, niche, or has a low ceiling) has also been disproved: Besi's 2026 Q1 orders doubled YoY to €269.7m and revenue grew 28.3%. The market is not dismissing it; it has awarded a premium far above peer ASMPT (TTM P/E about 54x), and there have even been reports of takeover approaches from Lam Research and Applied Materials (Reuters, March 2026, with the company hiring an investment bank to evaluate). An asset pursued by giants is not "dismissed".

  The only possible perception gap is a two-sided "too far out to see", and both bulls and bears may be looking in the wrong direction. On the bull side, "too far out to see" means extrapolating AI capex and HBM/advanced packaging demand as a straight line that never pulls back, assuming hybrid bonding will inevitably spread across logic, memory, CPO, consumer, and other use cases, and assuming Besi can monopolize the excess profit pool. That makes investors willing to pay more than 100 times Owner Earnings for the "most successful future version". On the bear/value side, "too far out to see" is the report's core position: even if HB succeeds long term, returns for buyers at today's price still depend heavily on the simultaneous realization of two fragile premises, "very high growth + no valuation decline". And the sell-side 12-month average target price is only about €252.55, below the current price (implying about 11% downside). In other words, even the bullish consensus price is already below the current price. This shows that the market is not arguing over "whether the narrative is true", but "how much margin of safety remains at this price". That is the substance of the report's "good business, bad price" judgment: the mismatch is more likely that price is too high relative to value, not that the market has failed to see the value.

  Narrative inflection points: positive catalysts can strengthen the story and "drag" the high valuation into reasonableness, while negative catalysts can trigger multiple compression. On the positive side, HB moving from validation to broad mass production, revenue approaching the report's €1bn+ level, credibility of operating margin returning to the 40% target, AMAT collaboration advancing die-to-wafer hybrid bonding toward high-volume manufacturing, and even a concrete takeover offer would all help earnings digest the valuation. Recently, Needham named Besi a Top Pick for HBM hybrid bonding, representing this side of sentiment. On the negative side, there is already a real sample: in early March 2026, Samsung, SK Hynix, and JEDEC discussed relaxing the thickness standard for next-generation HBM, and the market worried this would weaken the urgency of adopting hybrid bonding (about $3 million per tool, far more expensive than thermo-compression bonding at $1–2 million). Besi's share price plunged more than 15% in one day. This is a textbook demonstration of a "narrative inflection point": fundamentals had not yet deteriorated, but merely questioning the timetable of the growth story caused a high-valuation stock to pull back first. Other negative triggers align with the report's "reassessment signals": HB order growth slows and does not convert into revenue for 2–3 quarters, advanced packaging mix rises but margins do not, major-customer concentration rises alongside order delays, or market style rotates from "growth" to "cash returns".

  The honest landing point for this question: Besi does not fit the classic Baillie Gifford script of "why has the market not realized it yet". Its problem is not "being buried", but "being fully priced, and perhaps overdrawn". The narrative is known by everyone; the disagreement is only valuation. For a highly cyclical equipment leader near historical highs, with even bullish consensus target price below the current price, the real "perception gap" is not "the market cannot see how good Besi is", but "whether the market is overestimating the durability of AI advanced-packaging capex and the certainty of Besi's exclusive benefits". The report gives "Watch" and places the ideal buy range at €60–90 precisely because of this judgment: the value is real, but today's price has already paid in advance for many years of future success.
