Synaptics acquisition revised to $123 cash as rival bid reshapes deal

Synaptics is in the middle of an Edge AI transition, building Astra AI-native embedded compute, wireless connectivity, and multimodal sensing products for intelligent connected devices. The filing does not change that operating strategy; it changes who will own it and how shareholders are paid.

The deal now offers certainty, but at a lower headline value than the original structure. Onsemi will pay $123 per Synaptics share in cash, for approximately $5.7 billion, versus approximately $7 billion under the June agreement. The prior transaction was an all-stock deal based on 1.350 onsemi shares per Synaptics share, so shareholders give up exposure to onsemi's future upside in exchange for fixed consideration.

The competing bid forced a renegotiation, but did not produce a higher standalone offer. Synaptics says the unsolicited proposal was initially judged a “Superior Proposal,” then ceased to qualify after further negotiations with onsemi. 〔0〕 That makes the revised agreement a credible competitive-process outcome, but the filing does not disclose Party A's final price or terms, so it cannot establish that $123 was the highest economic offer available.

Execution risk has narrowed, but the merger is still not closed. Onsemi has fully committed debt financing and the agreement has no financing condition. 〔1〕 U.S. Federal Trade Commission approval is already in hand, but Synaptics shareholder approval and other regulatory approvals remain outstanding, with closing still targeted for mid-2027. 〔2〕

Bottom line: This is a mixed revision rather than a clean upgrade: Synaptics shareholders receive fixed cash and reduced financing uncertainty, but the stated transaction value falls from roughly $7 billion to $5.7 billion and the original onsemi-share upside disappears. The business story remains an acquisition into onsemi's intelligent-edge and AI strategy, not a new standalone operating inflection.
