ON Semiconductor has announced its intention to acquire Synaptics through an all-stock transaction valued at approximately $7 billion, marking the company’s most significant acquisition to date.
ON Semiconductor Corporation, ON
The announcement triggered a significant selloff in ON shares, which declined roughly 14% to $102.35 during Friday’s premarket hours. This represents a notable pullback for a stock that had climbed 119% year-to-date, riding the wave of semiconductor sector enthusiasm.
Meanwhile, Synaptics shareholders celebrated the news. The company’s stock jumped approximately 11% to $140 in Thursday’s after-hours session, reflecting the acquisition premium being offered.
According to the merger agreement, Synaptics shareholders will receive 1.35 shares of ON Semiconductor for every Synaptics share they own. This exchange ratio delivers approximately a 19% premium based on the 10-day volume-weighted average closing prices for both companies.
Both boards of directors have unanimously endorsed the transaction. However, the deal must still secure approval from Synaptics shareholders and navigate regulatory reviews before completion, which the companies expect to occur by mid-2027.
The rationale behind the merger focuses on what ON and Synaptics describe as “physical AI” — artificial intelligence that operates directly on edge devices rather than depending on cloud-based processing. Applications include self-driving cars, automated industrial equipment, and smart connected devices.
Synaptics contributes its Astra platform, which integrates AI processors, neural processing units, and wireless connectivity technologies such as Wi-Fi, Bluetooth, and GPS.
Strategic Advantages for ON Semiconductor
ON Semiconductor has historically focused on analog semiconductors serving automotive and industrial sectors. While the company has made inroads into data center markets, it hasn’t been recognized as a major AI player — this acquisition aims to change that narrative.
CEO Hassane El-Khoury characterized the deal as strategically positioning the company at the convergence point of sensing, decision-making, action, and real-time adaptation capabilities.
ON projects the acquisition could expand its total addressable market by between $30 billion and $243 billion by 2030, though this broad range reflects significant uncertainty surrounding edge AI adoption rates.
The company forecasts the deal will boost non-GAAP earnings per share within 18 months following completion, targeting $200 million in annual cost synergies.
Synaptics President and CEO Rahul Patel emphasized the all-stock nature of the transaction as a strategic advantage, noting it enables Synaptics shareholders to maintain equity exposure to the combined entity’s growth prospects.
Transaction Details and Advisory Teams
On a fully diluted basis, former Synaptics shareholders will control approximately 12% of the merged company. Additionally, one member of Synaptics’ board will join ON Semiconductor’s board as part of the merger terms.
Morgan Stanley served as primary financial advisor to ON Semiconductor, with J.P. Morgan Securities providing additional advisory services. Qatalyst Partners represented Synaptics in the transaction.
ON stock had surged 119% year-to-date prior to Friday’s session, propelled primarily by broad semiconductor sector valuation expansion rather than specific AI-driven revenue growth.
The merger remains contingent upon standard closing conditions, with the companies targeting mid-2027 for completion.
