onsemi Trades $7 Billion in Stock for $5.7 Billion in Cash to Land Synaptics

Introduction

On October 1, 2026, onsemi and Synaptics did something unusual for a semiconductor merger already three months old: they cut the headline price and raised the certainty at the same time. The two companies amended the merger agreement they signed on June 25, 2026, replacing an all-stock structure worth roughly $7 billion with an all-cash offer of $123 per share valued at approximately $5.7 billion.

The rewrite followed an unsolicited competing proposal for Synaptics from an unnamed third party. Both boards reviewed it. Both boards then decided the amended onsemi deal was the better one, and both stocks rose — onsemi about 8% to $86.64 in morning trading, Synaptics about 14% to $121.32, according to market coverage of the announcement. Those are unusual moves in opposite directions, and they say something specific about what actually changed.

Why onsemi Switched From Stock to Cash

The original agreement, announced June 25, 2026, used a fixed exchange ratio of 1.350 onsemi shares for every Synaptics share, a structure worth roughly a 19% premium to the volume-weighted average closing prices of both stocks in the ten trading days before announcement. Fixed ratios appeal to a target because they lock the arithmetic. They are also a bet by the acquirer that its own share price will hold where it stood on signing day.

That bet did not hold well enough. When a third party arrived with an all-cash offer, a floating share exchange became the obvious weak point in the structure, and onsemi rewrote the deal around it.

Hassane El-Khoury, onsemi's president and chief executive, framed the switch as value creation rather than capitulation. "The all-cash transaction delivers higher value to our shareholders through lower total cost consideration, and we now expect the transaction to be immediately accretive to non-GAAP EPS upon closing," he said in the company's announcement.

Both halves of that sentence matter. Paying cash means onsemi issues no new shares, so its existing shareholders keep their percentage claim on the combined company. And a deal bought with cash, struck against a target trading below the offer price, registers as accretive sooner than one whose value depends on an exchange ratio the market has already repriced.

Financing the Gap

Closing a $5.7 billion cash deal when the prior version was $7 billion in stock requires real funding. onsemi disclosed that it has obtained fully committed debt financing from Morgan Stanley, and its filing with the Securities and Exchange Commission specifies a commitment for up to $2.45 billion in senior secured term loans, subject to customary closing conditions.

Two details in that filing deserve attention from anyone underwriting the transaction. First, the amended agreement removes financing as a condition to closing, so onsemi cannot walk away over a credit market. Second, the commitment is senior and secured, which places it ahead of equity in onsemi's capital structure precisely when integration risk is at its highest.

The balance sheet has some room to absorb that. onsemi reported $3.9 billion in cash and short-term investments at the end of the second quarter of 2026, total liquidity of $5.4 billion, and quarterly free cash flow of $425 million. It also repurchased $332 million of stock during the quarter — a buyback the shift to cash preserves, since the share count is no longer being expanded.

The amendment also strips out several closing conditions onsemi had been carrying: effectiveness of a registration statement, approval to list onsemi shares, absence of a continuing material adverse effect on onsemi, and closing tax opinions. onsemi said it intends to withdraw the registration statement. The agreement additionally drops the requirement that a Synaptics director join onsemi's board.

What onsemi Is Actually Buying

Synaptics is a fabless company focused on AI at the edge, supplying embedded compute, wireless connectivity and multimodal sensing for touch, display, biometrics, audio, video and vision applications. That is a genuinely different business from onsemi's, which is built on intelligent power and sensing for automotive, industrial and AI data center customers. onsemi is an S&P 500 company headquartered in Scottsdale, Arizona; Synaptics is based in San Jose, California.

El-Khoury's strategic case rested more on cash generation than on product adjacency. "Synaptics is accretive to our long-term model, with a strong growth outlook and attractive gross margin profile that will help accelerate onsemi's evolution," he said, adding that the deal brings "highly profitable human-machine interface, and sensing products businesses that generate strong and predictable cash flows, providing the combined company with a durable funding engine to accelerate our connected compute capabilities."

The growth figures cited on the August 3 earnings call support that framing. Synaptics management expects fiscal 2026 Core Internet of Things revenue to grow more than 40% to over $385 million, driven by what it describes as Edge AI and Physical AI design wins. On that same call, onsemi management said Synaptics' "market-leading connected compute capabilities" complement onsemi's "strength in power, sensing, and control."

On synergies, onsemi raised its own expectations without making the headline number bigger. It still points to the $200 million of annual run-rate synergies announced in June, and now describes incremental revenue synergies plus the insourcing of a portion of Synaptics' production as additional benefits expected only after the first 18 months following closing. Framing the extra value that far out is how companies avoid having to defend it every quarter.

Rahul Patel, Synaptics' president and chief executive, argued the case for certainty from the other side of the table. "By transitioning to an all-cash structure, we are providing value certainty at a meaningful premium as compared to current value," he said. Synaptics' board, having reviewed the competing proposal alongside its financial and legal advisors, unanimously determined that the amended onsemi transaction remained in the best interests of Synaptics and its shareholders.

The Long Road to a 2027 Close

The amended agreement still targets a close by mid-2027, which is a long time for a semiconductor deal that has already survived one bidding contest.

The United States Federal Trade Commission has approved the transaction, and regulators in other jurisdictions are still reviewing it. Synaptics shareholders have not yet voted. Synaptics is required to file a preliminary proxy statement on Schedule 14A within 10 days of the amendment, and to convene its stockholder meeting within 30 days of learning that the proxy will not be reviewed or that SEC staff has no further comments.

Award treatment adds a wrinkle proxy readers will have to parse, because not everything is paid in the same currency. Synaptics restricted, performance and market stock unit awards that are assumed and converted use a conversion ratio set at $123 divided by the average of onsemi's volume-weighted average share prices over five consecutive trading days ending three trading days before the merger's effective time — meaning some holders are still receiving onsemi stock, converted rather than issued directly. Vested, closing-vested and non-employee director awards are canceled for cash at $123 per share. Appraisal rights under Section 262 of the Delaware General Corporation Law are also addressed in the amended agreement.

Conclusion

It is tempting to read a cut from $7 billion to $5.7 billion as onsemi losing a bidding war. The price action argues against that. Both stocks rose on the news, which is what tends to happen when a deal's probability of closing improves even as its headline value falls.

The structural change is the real story. onsemi traded dilution for leverage at a moment when the parts market it sells into, and the cost of debt available to fund a term loan, are both moving against acquirers. It bought certainty for the target and growth funded by borrowing for itself, and deferred the harder questions — insourcing production, converting equity awards, defending a combined business across multiple jurisdictions — to 2027.

That is a defensible trade when your own stock is the element that went wrong in the original structure. It is also a trade that leaves onsemi carrying debt into the integration, and into whatever broader consolidation cycle follows.
