Besi Shares Fall 3 Percent as ASML Develops Rival Hybrid Bonding Product

October 18, 2026 – Shares of Dutch computer chip packaging equipment maker BE Semiconductor Industries fell 3 percent following reports that industry giant ASML is actively developing a rival hybrid bonding product.

The sharp equity decline was directly triggered by a detailed report published by influential semiconductor research firm Semi-analysis.

For macroeconomic allocators, the development highlights intensifying competition within the advanced chip packaging sector as the industry searches for new technological avenues to unlock next-generation performance gains.

Trading desks observe that Besi shares dropped to 158.50 euros in Amsterdam trading, while ASML shares simultaneously advanced 1.1 percent to reach 1,480 euros.

Patent Filings and Market Impact

The comprehensive Semi-analysis report examined 27 distinct patent families filed by ASML between December 2022 and November 2024.

Industry analysts concluded that these technical filings strongly indicate the ongoing development of a proprietary die-to-wafer hybrid bonding tool.

Hybrid bonding is a critical advanced packaging technology that directly joins 2 chip surfaces without metal bumps, significantly improving thermal management and processing power.

Besi currently dominates the global die-to-wafer bonding market and remains the only equipment supplier with tools actively operating in volume production.

Quantitative analysts note that if ASML successfully commercializes a competing product, advanced logic customers may instinctively adopt tools from the larger, deeply entrenched equipment provider.

Valuation Concerns and Analyst Downgrades

The potential entry of ASML poses a severe downside risk to Besi's long-term growth narrative, which heavily depends on its undisputed leadership within the hybrid bonding segment.

Bank of America recently downgraded Besi to a neutral rating and nearly halved its institutional price target, explicitly citing the looming threat of ASML's expanding advanced packaging pipeline.

Asset managers emphasize that while ASML has not formally confirmed a commercial tool release, the company recently acknowledged its continuous evaluation of how the 3-dimensional integration industry will evolve.

Corporate leadership at ASML previously stated they are actively determining where the enterprise's unparalleled precision engineering expertise can deliver additional value to semiconductor manufacturers.

Equity funds project that as the physical limits of traditional lithography approach, advanced packaging technology will become the primary structural battleground for global semiconductor equipment manufacturers heading into 2027.
