BESI Shares Hit Record on Renewed Takeover Interest From Lam Research and Applied Materials

Hybrid-bonding packaging viewed as critical for AI chips has put the Dutch firm in play.

Overview

  • BE Semiconductor Industries is working with Morgan Stanley to evaluate acquisition approaches from potential buyers, with Lam Research among the parties in talks.
  • Shares jumped as much as 14% to an intraday record of €199.85 after reports of revived interest, with the stock last up around 10%.
  • Applied Materials, considered a potential acquirer, holds about 9% of BESI following an April 2024 investment and has collaborated with the company on hybrid-bonding technology.
  • Discussions that began in mid-2025 paused earlier this year due to U.S.–EU tensions linked to President Donald Trump’s moves regarding Greenland and have since resumed.
  • Any deal would undergo a Dutch national-security review, and BESI, Morgan Stanley, and Applied Materials declined to comment while Lam Research did not immediately respond.
