(Reuters) – U.S chipmaker Onsemi said on Monday it was withdrawing its $6.9 billion offer for Allegro MicroSystems, a month after the semiconductor solutions provider rebuffed the latest offer from its larger rival.

Onsemi’s shares rose 4% in extended trading, while Allegro fell 7%.

Allegro had rejected Onsemi’s $35.10 per share offer in March.
