onsemi Cuts Synaptics Deal to $123/Share, $5.7B All-Cash

onsemi (NASDAQ: ON) and Synaptics Incorporated (NASDAQ: SYNA) announced on 1 October 2026 that they amended their 25 June 2026 merger agreement, cutting the price to $123 per share in cash from the roughly $7 billion all-stock deal struck in June. The revised transaction carries an aggregate value of approximately $5.7 billion. onsemi said the amendment followed an unsolicited competing proposal from a third party and that the deal is now expected to be immediately accretive to its non-GAAP earnings per share.

Context — why did onsemi cut its Synaptics offer?

The trigger was an unsolicited competing proposal from a third party, which onsemi said prompted a review of the original terms. The company did not disclose the identity of that bidder, the size of the proposal, or whether it was cash or stock. That leaves the market without a reference point for how competitive the process actually became.

The prior agreement, signed 25 June 2026, was valued at approximately $7 billion. The revised deal is roughly $5.7 billion, a reduction of about $1.3 billion, or close to 19% of the original headline value. onsemi frames the cut as a gain rather than a concession, arguing it delivers "higher value to our shareholders through lower total cost consideration."

The shift from a stock-based structure to all cash is the substantive change. Cash removes the arbitrage exposure Synaptics holders carried to onsemi's own share price between signing and close. Patel said the move provides "value certainty at a meaningful premium as compared to current value," language that points to where Synaptics traded before the amendment.

onsemi has secured fully committed debt financing from Morgan Stanley. The amended agreement drops any closing condition tied to onsemi's financing, a term the original deal carried. For a buyer using cash on hand plus committed debt, removing that condition reduces one path to a broken deal.

Macro conditions matter less here than deal mechanics. This is a bilateral, negotiated amendment, not a repricing driven by rates. The relevant backdrop is the regulatory calendar, and on that front onsemi already has the United States Federal Trade Commission's approval.

Data — what the numbers show

The headline figures are the price and the total. onsemi will pay $123 per share in cash for an aggregate value of approximately $5.7 billion, against approximately $7 billion for the prior agreement. Both figures come from the companies' joint announcement.

The before-and-after comparison is stark on structure. Before: roughly $7 billion, stock consideration, a financing closing condition, no stated EPS accretion. After: roughly $5.7 billion, all cash, no financing condition, immediate non-GAAP EPS accretion expected.

Synaptics shareholders receive a fixed $123 in cash per share rather than a variable number of onsemi shares. That converts their outcome from a bet on onsemi's equity into a fixed claim, subject only to the deal closing. The trade-off is the loss of upside in the combined company.

onsemi's stated overlap target remains $200 million in annual run-rate cost savings. The company said it has identified incremental opportunities beyond that, from revenue synergies and insourcing a portion of Synaptics' production. onsemi expects those additional benefits to be realized after the initial 18 months post-close.

Closing is still expected by mid-2027. That timeline is unchanged from the original agreement, and it is subject to Synaptics shareholder approval, regulatory clearances in other jurisdictions, and customary conditions. onsemi did not disclose the revised deal's implied multiple on Synaptics revenue or earnings.

Analysis — what it means for semis and the arb crowd

The read-through for merger arbitrage desks is a narrower spread and a cleaner structure. An all-cash deal with committed financing and no financing condition removes two of the three standard reasons a signed merger breaks: funding risk and buyer-stock correlation. The remaining risk is regulatory and shareholder approval.

The FTC has already cleared the transaction. Regulators in other jurisdictions are still reviewing it, and onsemi did not name them or give a timetable. That is the live variable for anyone modeling a close date.

For onsemi holders, the math is straightforward. Paying roughly $1.3 billion less for the same asset base, financed partly with debt, mechanically improves the earnings attributable to each share. That is the basis for the company's immediate non-GAAP EPS accretion claim. Whether the accretion holds depends on the cost of the Morgan Stanley financing, which onsemi did not disclose.

The counter-argument is strategic. onsemi is taking on debt and cash outlay to buy human-machine interface and sensing businesses, plus AI data center exposure. If Synaptics' growth outlook softens after close, a fixed cash price looks worse than stock would have. El-Khoury's position is that Synaptics brings "highly profitable" HMI and sensing products that generate "strong and predictable cash flows."

Positioning is likely shifting. Synaptics holders who wanted onsemi equity exposure now get cash instead and must redeploy. onsemi holders who disliked dilution from the original stock deal get a smaller, debt-funded transaction.

Outlook — what to watch next

Three catalysts matter. First, the Synaptics special meeting and proxy filing; Synaptics will file a preliminary proxy on Schedule 14A, then a definitive proxy, and the company has not given a meeting date. Second, regulatory clearances outside the United States, which onsemi said are under review with no disclosed timeline. Third, the mid-2027 close target.

On financing, watch for terms of the Morgan Stanley commitment. onsemi said the financing is fully committed but did not disclose pricing, tenor, or covenants. Those details will shape the actual accretion math.

On the operational side, onsemi said the incremental revenue synergies and insourcing benefits arrive after the first 18 months post-close. That places their realization beyond the mid-2027 close, into 2029. Until the proxy lands, the spread between $123 and Synaptics' market price is the cleanest real-time gauge of deal-completion risk.

What does the $123 per share price mean for Synaptics shareholders?

Synaptics holders are being offered a fixed $123 in cash for each share, replacing the variable stock consideration in the June agreement. That removes exposure to onsemi's share price between now and closing. Synaptics CEO Rahul Patel described the structure as providing "value certainty at a meaningful premium as compared to current value." The payment is contingent on the deal closing, which remains subject to a Synaptics shareholder vote, regulatory approvals outside the US, and customary conditions, with closing still targeted for mid-2027.

Why is onsemi paying less for Synaptics than it agreed in June?

onsemi said an unsolicited competing proposal from a third party prompted the amendment, and that the revised terms represent "a more financially attractive transaction" for its shareholders. The aggregate value fell to approximately $5.7 billion from approximately $7 billion. onsemi also switched the consideration to all cash and removed a closing condition tied to its financing, which it has secured from Morgan Stanley. The company did not identify the competing bidder or disclose the proposal's terms.

What synergies does onsemi expect from the Synaptics acquisition?

onsemi reiterated $200 million in annual run-rate cost synergies, the same figure attached to the original June agreement. Beyond that, the company said it has identified incremental opportunities from revenue synergies and from insourcing a portion of Synaptics' production. onsemi expects those additional benefits to be realized after the initial 18 months following close. The company did not quantify the incremental amount or specify which product lines or manufacturing sites are involved.

Bottom Line

onsemi is buying Synaptics for $1.3 billion less, in cash, and now expects the deal to lift earnings per share immediately.
