Everything About AI
NextFin News - Applied Materials Inc. has lifted its ownership of Dutch chip-equipment specialist BE Semiconductor Industries to roughly 20% of outstanding shares, a move that stops well short of a full buyout while deepening the two companies' grip on the hybrid-bonding technology that has become the choke point of AI chip packaging. The stake increase, announced Monday, follows a March bidding contest in which Applied and Lam Research both pursued the maker of the industry's most precise die-bonding tools, and it signals that Applied has chosen to lock in strategic control through partnership rather than a change of control that would invite antitrust scrutiny, integration risk, and a far higher price.
The Deal: A 20% Anchor Position, Not a Takeover
Applied Materials first entered Besi in April 2025 with a 9% stake, making it the Dutch company's largest shareholder. Monday's statement takes that position to about 20% of outstanding shares in a company valued at roughly $13 billion. Alongside the increased stake, Besi said it would step up collaboration with Applied, citing the European equipment maker's growing role in energy-efficient AI computing.
The structure is the story. A full acquisition of Besi would have carried a price tag in the $15 billion to $16 billion range, based on the valuation discussed during the March approach, when Besi's shares touched an intraday record of €199.85. It would also have combined two of the most powerful franchises in advanced packaging under one roof — a transaction certain to draw close regulatory review in Europe and the United States. Instead, Applied has secured a stake large enough to carry substantial influence over Besi's strategic direction without triggering the change-of-control scrutiny, integration risk, and premium pricing that a takeover would demand. Under Dutch corporate rules, a formal blocking position on special resolutions sits above 25%, so 20% is better understood as an anchor investment with outsized sway rather than a veto position.
The sequencing is deliberate. On October 1, just weeks before the stake increase, the two companies expanded their partnership by bringing Besi into Applied's EPIC Center as an Innovation Partner, extending co-development beyond hybrid bonding into new interconnect architectures and panel-level integration. The relationship now runs from joint research in Singapore, where the companies established a Center of Excellence in 2020, through co-developed production systems, to a 20% ownership link. That Center of Excellence produced Kinex, the industry's first integrated die-to-wafer hybrid bonding system, combining Applied's front-end wafer and chip processing with Besi's die placement, interconnect, and assembly precision.
We view this as a strategic, long-term investment that demonstrates Applied Materials' commitment to co-developing the industry's most capable hybrid bonding solution, a technology that is becoming increasingly important to the advanced logic and memory chips at the foundation of AI.
Terry Lee, corporate vice president and general manager of Heterogeneous Integration and Packaging at Applied Materials, said those words when the initial investment was announced in April 2025. Monday's move is the same thesis, scaled up.
Why Hybrid Bonding Became the Most Contested Technology in Chips
Hybrid bonding connects chips using direct copper-to-copper bonds, eliminating the solder bumps and micro-bumps that have traditionally linked stacked dies. The result is higher interconnect density, shorter wiring between chiplets, and materially better power efficiency — precisely the parameters that matter as AI accelerators grow larger and memory stacks grow taller. In packaging, the industry has long chased finer pitch; hybrid bonding is what happens when the pitch gets so fine that metal pads can be fused directly, face to face, without an intervening bump.
Besi's position in this niche is unusually concentrated. The company's tools deliver the alignment accuracy required to stack 16 or 24 layers of memory dies, which is why most AI accelerator and high-bandwidth memory roadmaps now depend on the kind of precision Besi supplies. As the memory industry moves toward HBM4 in 2026 and 2027, hybrid bonding transitions from an emerging technique to a production necessity. Besi's cumulative unit demand has already exceeded 215 systems, and its hybrid bonding orders more than doubled in fiscal 2026 compared with the prior year.
The financials confirm the inflection. In the third quarter of 2026, Besi reported revenue of €283.4 million, up 113.6% year over year and 13.4% sequentially. Net income rose 323.7% to €107.2 million, pushing net margin to 37.8% — double the year-earlier level of 19.0%. Orders climbed 96.1% year over year to €342.6 million, lifting the last-twelve-months order book to €1.2 billion. Gross margin reached 65.2%, three points above the prior-year quarter, helped by a favorable product mix and price increases passed through to offset higher supply-chain costs. Through the first nine months of 2026, revenue rose 69.0% to €718.1 million and orders jumped 108.3% to €905.2 million, with net income up 179.1% to €247.8 million.
That order momentum is the real prize Applied is securing. Besi's backlog is not a speculative pipeline; it is a queue of systems that chipmakers need to install as they retool for HBM4 and chiplet-based architectures. Whoever controls the relationship with Besi controls the preferred path into those fabs — and into the conversations about what comes after HBM4.
The Lam Research Dimension: What a 20% Stake Buys
The March takeover reports put two suitors in the frame: Lam Research and Applied Materials, with Besi retaining Morgan Stanley to evaluate the approaches. Lam brings deep strength in electrochemical deposition and etch for advanced packaging — the steps that build the copper structures hybrid bonding ultimately fuses together. Besi owns the die-bonding step that aligns and joins the dies. A Lam-Besi combination would have created a near-complete advanced-packaging equipment suite under one roof, spanning from copper pillar formation through final bond.
Applied's 20% stake changes the geometry of that contest. With Applied now the anchor shareholder and an expanded co-development agreement in place, Besi is effectively aligned with Applied's packaging roadmap. Lam remains a formidable competitor with its own packaging portfolio, but it no longer has a clear path to control the category's most critical toolmaker. Applied has achieved much of the strategic benefit of an acquisition — preferential access, roadmap alignment, and insight into Besi's customer queue — at a fraction of the capital cost and with none of the regulatory exposure.
There is also a defensive logic. If Applied had not moved, Lam or another buyer could have. By raising its stake now, Applied raises the cost and complexity of any rival approach while preserving the option to go further later. A 20% position is a foothold, not a ceiling — and it puts Applied ahead of broad-based holders such as BlackRock, which held the largest position before Applied's April 2025 entry.
The Second-Order Effect: Packaging Moves Up the Equipment Hierarchy
The deeper implication of this deal is not about Besi alone. It is about where value is migrating inside the semiconductor equipment stack. For decades, the economics of chipmaking were dominated by the front end — the lithography, deposition, and etch steps that define transistors on a wafer. Packaging was a back-end afterthought, a lower-margin assembly step handled by a different set of suppliers.
Hybrid bonding collapses that distinction. Because it fuses dies with the same precision that front-end processes demand, advanced packaging now depends on the same materials-engineering disciplines that define wafer fabrication. That is why Applied — a front-end giant — has spent the past six years building a packaging franchise, and why it treats Besi not as a supplier but as a co-architect. It is also why Besi joined Applied's EPIC Center this month: the frontier of chip performance is no longer only the transistor; it is the connection between chiplets, and the connection is becoming as valuable as the compute.
This shift redistributes pricing power across the equipment landscape. Companies that own the bottleneck step in advanced packaging — hybrid bonding, thermo-compression bonding, high-accuracy die placement — gain leverage that extends beyond their own revenue line, because fabs cannot qualify a packaging flow without them. Applied's stake is a bet that this leverage will compound: as HBM4 ramps and chiplet architectures proliferate across foundries and logic designers, the packaging toolset becomes a gating item for the entire AI hardware buildout.
The second-order consequence is that Applied is not just buying exposure to Besi's growth; it is shaping the standard. Co-developed systems mean co-defined specifications, and the customers who adopt Applied-Besi hybrid bonding solutions early will find it costly to switch. That is the durable advantage a 20% stake helps protect — a standard-setting position that a pure financial investment could not secure and a hostile takeover could have jeopardized.
Cyclical Wave Riding a Structural Shift
The central question for investors is whether the force behind Besi's surge is cyclical or structural, because the answer determines whether today's valuation is justified or front-run. The two are present in different layers, and conflating them is the most common error in reading this story.
The cyclical leg is real and visible in the numbers. Equipment orders are inherently lumpy: customers pull deliveries forward or push them back based on capacity plans, and Besi's own fourth-quarter guidance — revenue flat to plus or minus 5% — is a textbook example of delivery timing rather than a change in end demand. The company's note that some customers requested Q3 deliveries be shifted into first-half 2027 capacity plans is exactly the kind of inventory-and-timing dynamic that has defined every semiconductor equipment cycle since the 1980s. On a purely cyclical read, the €1.2 billion backlog is a wave that will crest and then require new orders to sustain it.
But the structural leg is the stronger one. Hybrid bonding is not a capacity cycle; it is a change in how chips are built. The transition from solder bumps to direct copper-to-copper fusion is a permanent shift in the packaging architecture, driven by the physics of AI workloads: more chiplets, taller memory stacks, and power budgets that no longer tolerate bump-based interconnects. Once a fab qualifies a hybrid bonding flow for HBM4 or a chiplet product, it does not revert to bumps, because the performance and power penalty is too large. That is the definition of a structural shift — a regime change that will not revert on its own.
The practical implication is that the cyclical layer will produce volatility — quarterly delivery timing, digestion periods, margin fluctuations — while the structural layer sets the direction. Applied's 20% stake is a bet on the structural layer, hedged against the cyclical one: it captures the long-term compounding of hybrid bonding adoption without taking on the full operating leverage and integration risk of owning Besi outright.
The Counter-Thesis: Valuation, Adoption Risk, and a Flattish Outlook
The bullish case for Besi is not without its counters, and the company's own guidance gives skeptics material. For the fourth quarter, Besi expects revenue to come in 5% below to 5% above the third-quarter level, implying a range of roughly €269 million to €298 million. Management attributed the flattish outlook to customer delivery timing rather than weakening demand, noting that some customers requested delivery dates aligned with first-half 2027 production capacity plans. But the company also flagged that operating expenses will rise 5% to 10% due to higher strategic consulting costs — a line item that, read alongside the stake news, looks like a direct consequence of the deal uncertainty now surrounding the company.
Valuation is the second leg of the bear case. Besi trades at a price-to-earnings multiple above 60 times trailing earnings and roughly 31 times forward earnings, pricing in sustained hypergrowth. UBS, which double-downgraded the stock to Sell with a €159 price target in early October, argues that hybrid bonding adoption carries downside risk if customers qualify alternative solutions or if the technology's rollout slips. That concern gained traction in mid-October, when reports surfaced that ASML is working on a rival hybrid bonding product — a reminder that no equipment niche stays uncontested forever, and that Besi's near-monopoly is a function of timing as much as technology.
The falsifying signal is concrete. Besi's premium valuation rests on two assumptions: that hybrid bonding orders keep accelerating, and that the €1.2 billion order backlog converts to revenue at the guided 63% to 65% gross margin. If hybrid bonding orders fail to grow in the fourth quarter or fiscal 2027 while mainstream orders hold steady, or if backlog conversion slips below the guided margin range, the multiple has nowhere to hide. Cumulative unit demand of more than 215 systems is impressive, but the market is paying for the next several hundred, not the ones already shipped.
What Comes Next
The immediate catalysts are clear. Besi will report its fourth-quarter and full-year 2026 results on February 25, 2027, and investors will scrutinize three things: whether hybrid bonding orders kept accelerating, whether the €100 million share repurchase program announced alongside the third-quarter results begins to put a floor under the shares, and whether the flattish fourth-quarter revenue outlook was genuinely a timing issue or the first sign of digestion. Applied Materials' next earnings update will also matter, as investors look for evidence that the Besi relationship is translating into packaging revenue growth.
Beyond the numbers, the strategic question is whether 20% is a waypoint or a destination. The partnership expansion announced October 1 and the stake increase announced October 26 look like two moves in the same campaign: secure alignment, deepen co-development, and leave the door open for more. If hybrid bonding adoption accelerates as expected and Besi's backlog converts, pressure to formalize the relationship further will grow — from Applied, from Besi's other shareholders, and potentially from Lam Research, which still has reasons to want a seat at the table.
Three scenarios frame the path ahead. In the base case, Besi's Q4 revenue lands in the guided range, hybrid bonding orders continue to outpace mainstream orders, and Applied's stake remains a stable anchor while the two companies co-develop the next generation of bonding systems. In the upside case, ASML's reported entry into hybrid bonding validates the market rather than fragmenting it, demand for HBM4 tooling exceeds the €1.2 billion backlog, and Applied moves beyond 20% — either through open-market purchases or a negotiated increase. In the downside case, hybrid bonding adoption slows as customers dual-source or qualify alternatives, the backlog converts more slowly than guided, and the 20% stake becomes an illiquid, mark-to-market exposure on Applied's balance sheet rather than a strategic asset.
Applied Materials has made its bet: the future of AI chips depends on packaging, and the future of packaging runs through Besi. The 20% stake is the price of a front-row seat without buying the theater. The market will decide whether that was the shrewd middle path — or merely a down payment on a deal that still has to happen.
