ASML Hybrid-Bonding Plans Put Besi Shares Under Pressure as Memory Demand Adds a Second Risk

BE Semiconductor Industries shares came under pressure after Bank of America downgraded the Dutch chip-equipment maker to neutral, arguing that investors haven't priced in a competitive threat from ASML's planned move into hybrid bonding. Besi shares fell as much as 6.4% on Oct. 6 after the call, while Bank of America nearly halved its price target.

The decline adds to a sharp reset in sentiment. Besi was the Stoxx 600's worst performer in the third quarter, dropping about one-third during the period and standing roughly 40% below its June peak. The stock still remained up about 45% for the year, leaving room for investors to question whether its earlier valuation reflected too much confidence in rapid adoption of its packaging technology.

Hybrid bonding joins chip surfaces directly, supporting denser and faster semiconductor designs. Besi has established a leading position in equipment for the process, making ASML's stated interest in developing competing technology a direct challenge to the market that underpins Besi's growth case.

Bank of America analysts led by Didier Scemama identified ASML's public plans as the central risk. The concern extends beyond a future product launch: Besi could face higher research and development spending, pricing pressure, and uncertainty among customers deciding which equipment platform to adopt. Two US companies have also approached Besi, and one already owns a 9% stake, adding a takeover and strategic-control dimension to the debate.

Competitive pressure from ASML is arriving alongside a demand problem. Memory manufacturers have faced shortages and spending constraints that have raised doubts about how quickly they will adopt hybrid bonding, a technology Besi has depended on to support its next growth phase.

The combination matters because Besi's investment case requires both technical leadership and customer deployment. If memory companies delay purchases, Besi's revenue opportunity takes longer to materialize; if ASML enters while customers are still evaluating the process, the incumbent's position becomes harder to defend. The resulting pressure explains why the stock's retreat has outpaced the broader semiconductor equipment narrative, even as AI-related chip demand continues to support capital spending across the industry.

ASML remains the stronger company in the broader equipment market, but its shares also faced pressure in early October as investors reacted to reports of Chinese advances in deep-ultraviolet lithography. One account described a Shanghai-based, state-backed company beginning mass production of domestic immersion DUV tools and targeting 5 machines this year. The report triggered a sharp reversal in semiconductor-equipment stocks after an AI-driven rally.

Bank of America maintained a buy rating and a $2,845 price target for ASML, calling the selloff an overreaction. Traders and analysts cited the time required for China to scale production and close ASML's technology gap, while Koyfin data showed 40 of 44 analysts carrying buy or strong-buy ratings. These developments give ASML a separate competitive concern even as its hybrid-bonding plans pressure Besi.

Strong AI-chip demand is still supporting the semiconductor capital-equipment cycle. TSMC raised its 2026 revenue outlook and expanded its capital-spending plan, drawing fresh investor attention to equipment suppliers including ASML and Besi. The semiconductor sector remained up 72% for the year despite its recent pullback, according to Simply Wall.

That backdrop makes Besi's situation more specific than a broad sector collapse. Demand for advanced chips remains a favorable industry signal, but equipment suppliers benefit only when customers commit to particular manufacturing and packaging processes. Besi therefore faces an execution test: it must convert hybrid-bonding interest into orders before ASML becomes a credible alternative and before memory makers defer installations.

The next decisive signals will come from ASML's development timetable, customer validation, and Besi's ability to protect its lead without materially increasing research spending. Until those details become clearer, Bank of America expects ASML's potential entry to remain an overhang on Besi's valuation.

Besi's 9% shareholder and the approach from another US company also keep strategic alternatives in view, although the available accounts don't establish whether either approach will produce a transaction. For investors, the issue is less the current sales cycle than control of a packaging process tied to next-generation memory and AI chips. The stock's performance will hinge on adoption speed, competitive differentiation, and whether ASML's plans become a commercial product.
