27-year-old chip stock gets a rare win as rival bidder steps in
Onsemi (ON) revised its acquisition of Synaptics to an all-cash deal worth $5.7B ($123 per share) after a rival bidder's interest. The original stock-based deal would have diluted earnings, but the new cash deal is expected to be 11% accretive by 2027, according to Bank of America. Onsemi's stock has fallen significantly since the initial deal announcement.
