TSMC, Samsung stand to gain if Intel exits foundry business, Bernstein says

** Bernstein says TSMC 2330.TW and Samsung's 005930.KS foundry will benefit the most if Intel INTC.O exits chip manufacturing business

** Last week, Intel warned investors it may have to get out of the chip manufacturing business if it does not land external customers to make chips in its factories

** Brokerage says semiconductor equipment market, especially for EUV (Extreme Ultraviolet) supply chain would be negatively impacted since Intel is a major capex spender

** "Intel is a major contributor of EUV revenue with 15-20% contribution"- Bernstein

** Bernstein says if Intel exits manufacturing, TSMC's semiconductor material supplier Hoya could see its market share in EUV mask blanks grow from 70% to 100%, taking over the share currently held by Intel's supplier AGC

** "For TSMC & Samsung, time to redesign chips & build capacity means a time lag from Intel's decision to the actual change, but TSMC clearly will benefit if Intel turns fabless," brokerage says
