onsemi cuts Synaptics deal price to $5.7bn in revised merger
onsemi has revised its merger agreement with Synaptics, reducing the acquisition price from approximately $7 billion to around $5.7 billion after an unsolicited competing proposal from an unnamed third party prompted both boards to renegotiate terms. Under the amended deal, onsemi will pay $123 per share in cash, down from the price set when the agreement was first announced on 25 June 2026.
The lower headline price is being framed by onsemi's management as a financially superior outcome for its own shareholders. Hassane El-Khoury, president and chief executive of onsemi, said the revised structure is expected to be immediately accretive to non-GAAP earnings per share upon closing, which the original agreement was not. El-Khoury added that the company has identified revenue synergy opportunities and plans to insource a portion of Synaptics' production, with those benefits expected to materialise within 18 months of closing, on top of the previously announced $200 million in annual run-rate synergies.
The transaction will be financed through a combination of cash on hand and committed debt financing from Morgan Stanley. Notably, the amended agreement removes any closing condition tied to onsemi securing that financing, reducing one source of deal uncertainty.
What onsemi acquires
Synaptics brings a portfolio spanning human-machine interface products, touch and display controllers, biometric sensors, and embedded AI compute through its Astra platform, targeting edge devices in consumer, enterprise and industrial settings. El-Khoury described the combined company as having a "durable funding engine" from Synaptics' high-margin, cash-generative businesses, which would help fund investment in onsemi's connected compute and AI data centre ambitions.
Rahul Patel, president and chief executive of Synaptics, said the board had focused on delivering value certainty for shareholders and that the all-cash structure achieves that, noting it represents a meaningful premium to current market value. The Synaptics board unanimously approved the revised terms following advice from its financial and legal advisers.
Regulatory clearance from the US Federal Trade Commission has already been granted, and reviews in other jurisdictions are ongoing. Closing remains targeted for mid-2027, subject to Synaptics shareholder approval and remaining regulatory sign-offs.
Market and competitive context
The deal sits at the intersection of two of the semiconductor industry's more active strategic themes: the consolidation of analogue and mixed-signal portfolios and the push to capture AI-adjacent revenue beyond GPUs. onsemi has been repositioning itself around intelligent power and sensing for automotive and industrial markets; Synaptics gives it a foothold in edge AI compute and a broader sensing product line.
The broader semiconductor M&A landscape has been cautious since the collapse of high-profile deals in prior years under regulatory scrutiny, most notably Nvidia's abandoned Arm acquisition. The FTC's early clearance here suggests the combined entity does not raise concentration concerns in any single product market, though reviewers in other jurisdictions have not yet concluded their assessments.
For Synaptics shareholders, the revised per-share price of $123 is lower in absolute terms than the original agreement, but the all-cash structure eliminates exposure to onsemi share-price movements that a stock-component deal would have carried. With the competing proposal having failed to displace the onsemi transaction, Synaptics' options appear to have narrowed, giving the board limited leverage beyond securing the present certainty of cash consideration.
