BE Semiconductor Industries (BESI) Stock Soars on Takeover Buzz From Lam Research and Applied Materials

Key Takeaways

• Shares of BESI reached a record €199.85 on Friday following a Reuters report detailing acquisition interest from major U.S. semiconductor equipment manufacturers
• Among the interested parties is Lam Research (LRCX); Applied Materials (AMAT), which owns a 9% position, is also reportedly considering a bid
• The Dutch company has engaged Morgan Stanley to assess the potential offers
• Initial discussions kicked off in mid-2025 but were temporarily suspended in early 2025 amid U.S.-EU diplomatic friction over Greenland; negotiations have now restarted
• Under Dutch regulations, any transaction would necessitate a national security assessment

Shares of BE Semiconductor Industries exploded up to 14% on Friday, reaching an all-time high after Reuters disclosed that the Dutch advanced packaging equipment specialist is attracting takeover proposals from two American semiconductor giants: Lam Research and Applied Materials.

The equity most recently changed hands at approximately €194.25, up roughly 10%, valuing the Amsterdam-traded firm at about €14 billion ($16.2 billion).

During its session high of €199.85, the stock had more than doubled from the €79.62 trough registered in April 2025 — when concerns about U.S. trade tariffs had pressured semiconductor stocks broadly.

According to two individuals with knowledge of the situation, BESI has retained Morgan Stanley to review the incoming proposals. The advisory firm did not provide a statement.

One source indicated that Lam Research (LRCX) has been among the most active parties engaging in substantive talks with BESI. Shares of LRCX declined approximately 4.3% following the disclosure.

Applied Materials (AMAT) is also reportedly in the mix as a prospective acquirer. The Silicon Valley-based company secured a 9% ownership position in BESI during April 2024, establishing itself as the company’s largest investor. AMAT stock fell around 3.9% on Friday.

That earlier stake acquisition had already telegraphed strategic intentions. When the investment became publicly known in October 2025, BESI shares surged 12% in a single trading day as market participants began factoring in the possibility of a complete takeover.

The Strategic Technology Driving Interest

The attraction from these two industry leaders centers on a specific capability: BESI’s hybrid bonding technology.

This advanced process creates direct chip-to-chip connections through copper-to-copper interfaces, delivering enhanced data transmission speeds and reduced energy consumption. The technology has become increasingly critical as semiconductor manufacturers work to satisfy surging demand from artificial intelligence and high-performance computing sectors.

Advanced packaging has emerged as a significant constraint across the global semiconductor landscape. BESI and Applied Materials have collaborated on hybrid bonding development for an extended period, positioning AMAT as a logical strategic buyer.

Regulatory Challenges Loom Over Potential Transaction

The route to completing any deal remains complex. Negotiations among the interested parties commenced in mid-2025 but were temporarily suspended at the beginning of this year when diplomatic tensions escalated between the United States and European Union regarding President Donald Trump’s efforts to acquire Greenland.

Dutch regulatory frameworks mandate that any purchase of a business with strategically important technology must undergo a national security examination — a requirement that could extend timelines or introduce complications into any potential agreement.

Notwithstanding the earlier interruption, sources indicate that Lam Research maintains its interest and has recently engaged in discussions with BESI.

BESI’s official response was measured. The company stated it does not comment on “market rumours” and emphasized its dedication to pursuing its strategic plan as a standalone entity. Lam Research did not provide an immediate response to inquiries.

BESI shares were trading 10.44% higher at €194.25 as of the latest update.
