Applied Materials Is Up Nearly 9% Since Moving to Lift Its Besi Stake to 20%. Here’s What Hybrid Bonding Could Mean for the Stock by 2030
Applied Materials (AMAT) stock rose 8.79% after announcing it would increase its stake in BE Semiconductor Industries (BESI) to 20%. The move ties AMAT closer to hybrid bonding, a key process for high-bandwidth memory (HBM) used in AI processors. AMAT's management expects hybrid bonding to double its served available market, with a potential total return of 91% and an annualized IRR of 18% by 2030, according to the company.
