Onsemi Switches Synaptics Deal to $5.7 Billion in Cash

Onsemi revised its acquisition terms for Synaptics, agreeing to pay about $5.7 billion in cash instead of roughly $7 billion in shares.

Onsemi has changed both the size and the form of its proposed payment for Synaptics, replacing roughly $7 billion in shares with about $5.7 billion in cash. The revision shifts the central question for investors from how ownership would be divided to how the buyer will fund the purchase.

The revised terms were reported by Bloomberg Technology. The available details establish the new consideration but do not explain why Onsemi changed it, how the cash will be raised or when the acquisition is expected to close.

Both stocks were higher in live trading on October 2, 2026. At the supplied last-trade timestamp of 16:38:47 GMT, Onsemi’s ON shares were up 5.24% and Synaptics’ SYNA shares were up 14.27%. Those gains show a positive market response alongside the announcement, although the trading snapshot cannot establish that the revised deal caused the entire move.

Cash changes who carries the deal’s risks

The most consequential change is not simply the lower headline amount. Paying with shares and paying with cash distribute risk differently between the buyer’s existing shareholders and the target’s shareholders.

In a share-funded acquisition, target shareholders generally receive an ownership interest in the buyer. Their eventual outcome can therefore depend on the buyer’s share price and the performance of the combined business. The precise exposure depends on the exchange terms, which are not supplied here.

Cash consideration instead gives selling shareholders a stated monetary payment, subject to the transaction’s terms and completion. It does not require them to remain investors in the combined company to realize that payment. That can make the payout easier to evaluate, but it does not eliminate the risk that the acquisition is delayed or fails to close.

For Onsemi shareholders, replacing acquisition shares with cash removes the dilution associated with that proposed share payment. Dilution means existing owners hold a smaller proportion of a company after additional shares are issued. But avoiding acquisition-share issuance is not the same as avoiding a financial cost: the buyer must obtain the cash somewhere.

The revised agreement therefore trades an ownership question for a funding question. Without financing details, investors cannot yet judge whether that trade leaves Onsemi with a stronger or weaker financial position after completion.

The lower headline amount needs careful comparison

The reported consideration moves from roughly $7 billion in shares to about $5.7 billion in cash. An illustrative subtraction of those rounded figures produces a difference of roughly $1.3 billion. That calculation describes the gap between the reported headline amounts, not a verified reduction in the acquisition’s total economic cost.

Share consideration can change in market value, depending on how an agreement is structured. A cash amount and an earlier share-based valuation therefore are not necessarily directly comparable measures of what each shareholder would receive at closing.

The available information does not include a per-share cash payment, the earlier exchange ratio or the treatment of any other obligations. It also does not establish whether the quoted figures use precisely the same valuation basis. Those omissions limit how confidently investors can call the revision a discount.

It would likewise be premature to conclude that Synaptics shareholders accepted worse terms simply because the new headline number is smaller. A cash payment and an ownership stake offer different combinations of certainty, market exposure and future upside. Evaluating the bargain requires the actual transaction documents rather than the aggregate amounts alone.

Onsemi’s funding plan becomes the next test

A cash acquisition can be financed from existing cash, borrowing, other funding sources or a combination. None of those choices is confirmed in the supplied information, so the revised terms should not be treated as evidence that Onsemi has committed to a particular financing structure.

If existing cash is used, investors would need to assess the liquidity left for operations and investment. If borrowing is used, the questions become the cost of that debt, repayment obligations and the flexibility retained by the combined business. These are different routes to the same purchase, with different consequences for shareholders.

For a chipmaker, the funding decision also matters because acquisition spending competes with the resources available for product development, manufacturing commitments and other business needs. That is an analytical consideration, not evidence that Onsemi plans to cut any spending.

The cash switch does not explain the industrial logic of buying Synaptics. Nor does it establish expected savings, integration costs or a timetable for combining the businesses. Investors should separate the financing decision from the operating case: a clearer payment structure cannot by itself demonstrate that an acquisition will deliver attractive returns.

Stock gains leave completion questions unanswered

The supplied market snapshot showed a broadly positive trading session. The S&P 500 benchmark was up 0.71%, the Nasdaq 100 benchmark rose 1.07% and the Dow 30 benchmark gained 0.32%. Both Onsemi and Synaptics posted larger percentage gains than those benchmarks at the stated time.

That relative strength is relevant context, but it is not proof of investor agreement on every aspect of the revision. Synaptics’ gain could be consistent with investors assigning greater value to a cash outcome or greater confidence in completion. Onsemi’s gain could be consistent with approval of the revised consideration. The quotes alone cannot distinguish among those explanations.

The next useful disclosures would identify the cash payment per share, the source and conditions of financing, any required approvals and the circumstances under which either company could terminate the agreement. A closing timetable would also help investors evaluate how long capital remains exposed to transaction uncertainty.

For now, the confirmed change is substantial but specific: Onsemi has replaced a roughly $7 billion share payment with about $5.7 billion in cash. Synaptics shareholders face a different form of consideration, while Onsemi shareholders face a different financing burden. Whether that is a better bargain depends on details the headline amounts do not yet provide.

Frequently asked questions

What changed in Onsemi’s acquisition of Synaptics?

Onsemi revised the proposed consideration for its acquisition of Synaptics from roughly $7 billion in shares to about $5.7 billion in cash. The change affects both the headline amount and the form of payment. The supplied details do not identify the financing plan, per-share payout or expected closing date.

Why did Onsemi switch from shares to cash?

The available information does not establish Onsemi’s reason for changing the consideration. Cash can avoid the ownership dilution associated with issuing acquisition shares, but it also requires funding. Those are consequences of the revision, not confirmed explanations for management’s decision or evidence of a particular financing strategy.

Does the revision mean Onsemi is paying less?

The new reported headline amount is lower, but that alone does not establish a directly comparable reduction in total acquisition cost. Share consideration can vary in market value, and the supplied information does not include the earlier exchange terms or confirm that both amounts use exactly the same valuation basis.

What does cash consideration mean for Synaptics shareholders?

Cash consideration generally gives selling shareholders a stated monetary payout rather than an ownership interest in the buyer. That changes their exposure to the combined company’s future performance. However, payment remains subject to the transaction’s terms and completion, and the supplied information does not specify the cash amount per share.

How did the companies’ shares trade after the revision?

At the supplied last-trade timestamp of October 2, 2026, 16:38:47 GMT, Onsemi’s ON shares were up 5.24% and Synaptics’ SYNA shares were up 14.27%. Both exceeded the supplied benchmark gains. The intraday snapshot does not establish how much of either move was caused by the acquisition revision.

What should investors watch for next?

Investors should look for the cash payment per share, financing sources, funding conditions, required approvals and the expected closing timetable. Onsemi’s remaining liquidity and any borrowing obligations would help assess the buyer’s financial burden. Transaction documents would also clarify termination provisions and whether the reported consideration amounts are directly comparable.
