Over the past six months, ON Semiconductor's stock price has been impacted by several events. On June 25, 2026, onsemi announced an agreement to acquire Synaptics Incorporated in an all-stock transaction valued at approximately $7 billion, leading to a 23.66% drop in ON Semiconductor's stock price to $90.65 per share on June 26, 2026. Additionally, a class-action lawsuit was filed against onsemi in December 2023, alleging that the company made materially false and/or misleading statements between May 1, 2023, and October 27, 2023, regarding the stability and visibility of demand for its silicon carbide (SiC) products and the sustainability of its revenue growth, particularly by overstating the impact of long-term supply agreements (LTSAs). The lawsuit claims that on October 30, 2023, the CEO disclosed weakening automotive demand and a projected miss of its 2023 SiC revenue target, causing a nearly 22% drop in the stock price that day. As of October 7, 2026, ON Semiconductor's shares fell 4.4%, closing at $82.51, despite having risen 71.3% over the past 12 months. Insider activity over the past year showed insiders selling $21.3 million worth of shares with no purchases, potentially indicating a lack of confidence.
