SYNA · Synaptics Incorporated

The thesis

Synaptics' shares now trade as a claim on onsemi's $123 per share cash offer, which caps the upside near that price unless a rival bidder appears. Completion by mid-2027, which still needs a Synaptics shareholder vote and non-US regulatory approvals, settles the case. The shares closed at $121.10 on 2 October 2026, below the cash price.

On 1 October 2026 onsemi and Synaptics amended their 25 June 2026 agreement. Consideration changed from 1.350 onsemi shares per Synaptics share to $123 in cash. The companies put the deal at about $5.7 billion, against about $7 billion under the prior terms. They said the revision followed an unsolicited proposal from a third party that neither company has identified. Synaptics' board unanimously determined the amended deal remains in shareholders' best interests. Company announcement, 1 October 2026

The narrative is maturing: the price is now fixed in cash and coverage on 2 October 2026 centred on that price, with the next event a shareholder-vote notice that has no announced date. The earlier published read, which tied the shares to onsemi's stock price, no longer applies.

Bullish and bearish views on Synaptics Incorporated

The bull case on Synaptics Incorporated (SYNA), in brief: Consideration is now fixed in cash. The bear case: Upside is capped at the cash price.

Bull case

• Consideration is now fixed in cash. The amended agreement pays $123 per Synaptics share without interest, so the value no longer moves with onsemi's share price. Wells Fargo analyst Joe Quatrochi wrote that secured value reduces shareholder-vote risk. TradingView/Seeking Alpha, 2 October 2026
• Financing is committed. onsemi said it holds a fully committed senior secured term loan of up to $2.45 billion from Morgan Stanley, and the amended agreement carries no closing condition tied to onsemi's financing. Quartz, 1 October 2026
• US antitrust review is finished. The Federal Trade Commission granted early termination of the Hart-Scott-Rodino waiting period on 12 August 2026. Regulators in other jurisdictions are still reviewing. Merger update, 12 August 2026
• A rival bid remains possible. A third party made an unsolicited proposal before the amendment. Wells Fargo wrote that a bid meaningfully above $123 is unlikely. TradingView/Seeking Alpha, 2 October 2026

Bear case

• Upside is capped at the cash price. Wells Fargo cut its Synaptics rating from Overweight to Equal-weight on 2 October 2026 and lowered its target from $140 to $123. Rosenblatt kept a Neutral rating and raised its target to $123 the same day.
• The price fell for holders. The prior terms valued the company at about $7 billion and the amended terms at about $5.7 billion. The 52-week high is $147.57, above the cash price.
• Closing is nine months away. The companies expect completion by mid-2027, subject to the shareholder vote, regulatory approvals and customary conditions. The shares closed at $121.10 on 2 October 2026, below $123, so the market is pricing some delay or risk.
• The deal is no longer a tax-free reorganization. onsemi said the merger no longer qualifies under Section 368 of the Internal Revenue Code. Quartz, 1 October 2026
• Finance leadership is transitional. CFO Ken Rizvi resigned on 20 August 2026 and CEO Rahul Patel serves as principal financial officer through completion, per the company's 21 August 2026 announcement.

Price setup

The adjusted daily close on 2 October 2026 was $121.10. The 14-day relative strength index (RSI, a 0–100 gauge of recent buying pressure) read 76.3, after a jump on the revised-deal news. The same series shows the shares up 1.4% over three months and 17.9% below the 52-week high of $147.57.

The 18 September 2026 close was $93.11, under the all-stock terms. The move to $121.10 reflects the cash price, not a change in Synaptics' operating results.

With cash consideration fixed, the distance between the close and $123 is the market's price for time and completion risk. A narrowing toward $123 would indicate rising confidence in approvals. A widening would indicate doubt.

Crowding evidence is limited to attention: over a dozen outlets covered the revision on 2 October 2026, and trading was heavy. No Form 4 insider sales or share issuance were found for this period.

Catalysts, next 30 days

• Not yet scheduled — non-US regulatory decisions. Reviews are ongoing, with no announced decision dates.
• ~early November 2026, est. quarterly reports. The date falls outside the 30-day window and is not confirmed. A standalone Synaptics print matters less than deal progress.

Elapsed catalysts

• Not yet scheduled — merger proxy and vote date. Neither company has announced a shareholder-meeting date. The 15 September 2026 annual proxy covers ordinary annual-meeting items, not the merger. (passed 28d ago)

What would change the view

The case breaks if the cash deal loses its path to closing: a termination notice, a blocking regulatory decision, a failed shareholder vote, or a rival bid that the board deems superior. The 25 June 2026 agreement carried a $235.0 million termination fee payable by Synaptics on a superior proposal. Whether the amendment changed that fee was not disclosed in the 1 October 2026 announcement.

Price evidence matters too. A daily close below $115 would put the shares well under the $123 cash price and show the market pricing material completion risk. A higher rival offer would reshape the case upward, as the price would then reflect a contest, not a fixed-price spread.

What it trades with

With a cash price fixed, the shares should follow onsemi's share price far less than under the earlier stock terms. They now follow deal-spread behaviour: completion odds, interest rates and broad risk appetite. Analog and physical-AI semiconductor peers matter less. Onsemi shares rose nearly 6% on 2 October 2026 per Wells Fargo's summary, which reflects onsemi's own accretion case, not a move in Synaptics' value.
