On Semiconductor Climbs 8%, Synaptics Surges 14% as $5.7B Cash Bid Replaces $7B Stock Deal
On Semiconductor scrapped its stock deal for Synaptics and replaced it with cash, and both stocks surged on the news for reasons that point in opposite directions.

A revised takeover agreement is lifting both the buyer and the target in a chip deal that just got simpler. On Semiconductor (NASDAQ:ON | ON Price Prediction) stock is at $86.64, up 8% in morning trading. This follows the company replacing its $7 billion all-stock agreement to buy Synaptics (NASDAQ:SYNA) with a $5.7 billion all-cash bid.
Synaptics stock is up 14% to $121.32, a larger climb tied to a fixed cash price replacing a floating share exchange.
The iShares Semiconductor ETF (NASDAQ:SOXX) is up 3% to $590.75, while the Invesco QQQ Trust (NASDAQ:QQQ) trades at $752.16, up 1.36%. That gap shows how much of the move traces to the deal itself.
Cash Offer Replaces All-Stock Structure
Under an amended merger agreement, On Semiconductor will pay $123 in cash for each Synaptics share, replacing the all-stock structure. The amendment followed an unsolicited competing proposal for Synaptics from a third party.
On Semiconductor now expects the transaction to be immediately accretive to adjusted earnings per share upon closing. CEO Hassane El-Khoury stated: “The all-cash transaction delivers higher value to our shareholders through lower total cost consideration.” Funding comes from cash on hand and committed debt financing, with no closing condition tied to that financing.
Dilution Fades for On Semiconductor, Certainty Arrives for Synaptics
For On Semiconductor shareholders, the core change is the removal of dilution. Paying cash leaves the share count untouched, protecting buyback work that included $332 million of repurchases in Q2 2026.
A fixed cash price gives Synaptics investors certainty, and the Synaptics board unanimously backed the amended transaction.
Synaptics also brings growth. Its management expects fiscal 2026 Core Internet of Things (IoT) revenue to grow more than 40% to over $385 million, driven by Edge AI and Physical AI design wins. On Semiconductor management stated on the August 3 earnings call that Synaptics’ “market-leading connected compute capabilities” complement On Semiconductor’s “strength in power, sensing, and control.”
Debt Is the Price of Avoiding Dilution
The trade-off is debt. Cash and short-term investments totaled $3.9 billion at the end of Q2, with total liquidity of $5.4 billion. Quarterly free cash flow reached $425 million, a support for paying down new borrowing.
The U.S. Federal Trade Commission has approved the deal, but other jurisdictions are still reviewing it, and Synaptics shareholders must vote. On August 3, On Semiconductor expected the transaction to close in mid-2027.
What to Watch Next
Investors can watch for the Synaptics stockholder vote and remaining reviews in other jurisdictions before On Semiconductor closes the purchase, as details on the committed debt financing cost could shape how the market judges On Semiconductor’s balance sheet.
Immediate accretion and an AI data center business where management expects revenue to more than double in 2026 support the optimistic view (we covered seven suppliers riding that same AI infrastructure expansion, from power to cooling, in a free report). Risks center on new leverage and integrating Synaptics.
Synaptics shareholders now face an outcome fixed at the $123 cash price. Traders may watch whether On Semiconductor stock holds its gains as borrowing terms become clearer.
