Synaptics Stock Surges After onsemi Revises Merger to $5.7 Billion All-Cash Deal

Summary
Synaptics shares jumped after its merger agreement with onsemi was amended to an all-cash offer of $123 per share. The change, valuing Synaptics at $5.7 billion, was prompted by a competing bid from an unnamed party.
Synaptics (SYNA) shares surged nearly 14% in pre-market trading after the company and onsemi jointly announced a revised merger agreement. The transaction has been converted from an all-stock structure to an all-cash acquisition at $123 per share, giving Synaptics an approximate valuation of $5.7 billion.
Revised Deal Terms
The amended agreement, announced on October 1, 2026, provides Synaptics shareholders with a fixed cash value, removing the market volatility associated with the original all-stock deal from June 25, 2026. The new offer represents a significant premium over Synaptics' prior closing price of $106.15.
To support the acquisition, onsemi has secured $2.45 billion in fully committed debt financing from Morgan Stanley. The companies noted that the revised agreement's closing is not subject to a financing condition, a key detail that increases certainty for investors. Synaptics CEO Rahul Patel stated that the all-cash structure provides "value certainty at a meaningful premium."
Competing Offer Spurs Change
The shift to an all-cash deal was prompted by an unsolicited, non-binding proposal Synaptics received from an unnamed strategic party on September 2, 2026. The existence of a competing bidder spurred both boards to renegotiate the terms, ultimately leading to the enhanced offer from onsemi.
AdThe Synaptics board of directors has unanimously approved the amended terms, determining them to be in the best interests of shareholders. The revelation of a rival suitor signals strong strategic interest in Synaptics' business and technology.
Market Reaction and Outlook
Investors reacted positively to the increased certainty and higher valuation, driving the stock price up 13.8% in pre-open trading to $120.76, close to the acquisition price. This price action indicates a high degree of market confidence that the deal will be completed.
The transaction has already received U.S. antitrust clearance. The companies are targeting a closing by mid-2027, pending approval from Synaptics shareholders and remaining regulatory bodies.
