Pomerantz LLP Launches Investigation into ON Semiconductor Acquisition

The inquiry centers on the all-stock transaction unveiled on June 25, 2026, which proposed that Synaptics shareholders receive 1.35 shares of Onsemi stock for each share held. Market reaction was immediate and negative; Onsemi shares plummeted $28.09 on June 26, closing at $90.65. Investors impacted by this decline are being encouraged to reach out to Danielle Peyton at Pomerantz LLP to discuss potential class action participation.

Pomerantz LLP, a firm with a long-standing history in securities litigation, is examining whether Onsemi’s officers and directors acted in the best interests of their shareholders when entering the agreement. While the acquisition aims to expand Onsemi's footprint in the internet-of-things sector, the resulting volatility has prompted this legal review into the company's disclosures and business practices.
