ON Semiconductor has reached an agreement to purchase Synaptics through an all-stock transaction valued at approximately $7 billion, marking its biggest acquisition to date.
ON Semiconductor Corporation, ON
The announcement triggered a significant selloff, with ON stock declining roughly 14% to $102.35 during Friday’s premarket hours. This represents a notable pullback for shares that had climbed 119% year-to-date amid broader semiconductor industry momentum.
Synaptics shareholders experienced a more favorable reaction. The company’s shares jumped approximately 11% to $140 in Thursday’s after-hours session, as investors welcomed the premium valuation.
According to deal terms, Synaptics shareholders will receive 1.35 shares of ON Semiconductor for every Synaptics share owned. This exchange ratio equates to approximately a 19% premium calculated using the 10-day volume-weighted average closing prices for both securities.
Both companies’ boards have unanimously endorsed the transaction. The deal requires Synaptics shareholder consent and regulatory approvals before it can be completed, with a projected closing timeline of mid-2027.
The acquisition strategy revolves around what ON and Synaptics describe as “physical AI” — artificial intelligence that operates directly on edge devices rather than depending on cloud-based infrastructure. Applications include self-driving vehicles, industrial automation systems, and smart connected devices.
Synaptics contributes its Astra platform to the partnership, which integrates AI processing chips, neural processing units, and wireless connectivity solutions encompassing Wi-Fi, Bluetooth, and GPS technologies.
ON Semiconductor has built its reputation primarily around analog semiconductors serving automotive and industrial sectors. While the company has entered data center markets, it hasn’t been viewed as a leading AI-focused player — a perception this deal aims to change.
Chief Executive Officer Hassane El-Khoury characterized the acquisition as strategically positioning the company at what he termed the convergence of sensing, decision-making, action, and real-time adaptation capabilities.
ON projects the acquisition could broaden its total addressable market by anywhere from $30 billion to $243 billion by decade’s end, though the substantial range indicates considerable uncertainty surrounding edge AI market adoption rates.
The company anticipates the deal will enhance non-GAAP earnings per share within 18 months following completion, while targeting $200 million in annual cost synergies.
Synaptics President and Chief Executive Rahul Patel emphasized the all-stock transaction structure as strategically advantageous, enabling Synaptics shareholders to maintain ownership stakes in the merged entity’s growth trajectory.
Calculated on a fully diluted basis, former Synaptics shareholders will control roughly 12% of the combined organization. Additionally, one Synaptics board member will secure a seat on ON Semiconductor’s board under the merger agreement.
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 entering Friday’s trading session, propelled primarily by semiconductor sector valuation expansion rather than substantial direct AI revenue contributions.
The acquisition remains contingent upon standard closing conditions, with completion expected by mid-2027.
