ON Semiconductor (ON) rose 6.7% to $85.45 in morning trading after the company revised its $5.7 billion acquisition of Synaptics to an all-cash deal. The shift from a stock-based offer to a fully cash transaction has boosted investor confidence in the deal’s simplicity and reduced risk. The stock opened with a 7.2% gap up from the prior close and reached a session high of $86.90 before settling near $85.14 at the close of the latest 5-minute bar.
What Happened
ON Semiconductor announced that it would acquire Synaptics for $123 per share in cash, valuing the deal at $5.7 billion. This replaces the previous $7 billion stock-based agreement. The revised terms have been well received by the market, with ON’s shares rising in response to the clarity and reduced dilution risk. The deal is expected to unlock further synergies, with the companies identifying additional opportunities beyond $200 million in annual run-rate savings. The move has also been highlighted by several market analysts as a favorable outcome for both companies and their shareholders.
What The Data Shows
The stock has traded between $83.97 and $86.90 in the session so far, with a volume of 1.8 million shares, which is 0.2 times the 3-month average. ON’s market cap is $29.9 billion, with a P/E ratio of 51.3 and a beta of 2.00. The stock is currently within its 52-week range of $44.56 to $134.92. Over the past eight sessions, it has gained 6.1%, moving from $72.21 to $76.64. The stock also printed two fresh 52-week highs on October 2, 2026, indicating strong recent momentum.
What To Watch
ON Semiconductor is not scheduled to report earnings in the near term. Investors will likely continue to monitor the progress of the Synaptics acquisition and the broader semiconductor industry for signs of demand and pricing stability. Coverage of the deal is expected to remain active as the transaction moves toward completion.
