On June 29, Allegro MicroSystems rose 5.63% in regular trading, trading at $61.53/share, with turnover of $30.01 million, significantly outperforming the broader semiconductor sector.

On the news front, ON Semiconductor previously abandoned its $6.9 billion acquisition bid for Allegro and instead announced an approximately $7 billion all-stock acquisition of Synaptics. The market reacted sharply negative to ON Semiconductor's pivot, sending its shares down 20%, while TD Cowen downgraded ON Semiconductor from Buy to Hold with a reduced target price of $110. This strong backlash has prompted investors to reassess Allegro's standalone operational value and its potential strategic attractiveness as an acquisition target.

Allegro had initially fallen to approximately $57 after the acquisition expectations evaporated on June 26, when ON Semiconductor cited finding no viable path to complete the Allegro deal. However, the stock has since fully recovered those losses and reached a rebound high, as the market appears to view Allegro's independent positioning in magnetic sensors, power ICs, and exposure to automotive, industrial, and AI data center markets as increasingly compelling on a fundamental basis.
