Onsemi's $5.7 billion cash bid for Synaptics lands 16% above the market price

A competing bid normally pushes a price up, so a revision that takes about $1.3 billion off the headline needs explaining ^[1][2]. The June agreement paid Synaptics holders in onsemi stock ^[3], and onsemi's shares now sit nearly 40% below their June record ^[5]. Investopedia, in a report carried by Yahoo Finance, said the move to cash may ease doubts that built up after that drop ^[20]. The sources do not give the exchange ratio, so the old offer's value on Thursday cannot be rebuilt from them. Synaptics' own share price is a cleaner mark. A $123 price at a 16% premium ^[4] puts Thursday's close near $106 ^[2]. If the two headline values are on the same basis, the June terms implied about $151 a share ^[3].

On that evidence, Synaptics' board took certainty and a premium together, measured against a stock offer the market had already marked down. "By transitioning to an all-cash structure, we are providing value certainty at a meaningful premium as compared to current value," Rahul Patel, Synaptics' chief executive, said ^[18]. The counter-case is the upside his holders hand back. Onsemi stock is up 57% this year even after its slide ^[19], and a stock with that range could have carried a share-based offer back toward its June value.

Onsemi's chief executive, Hassane El-Khoury, presented the switch as a saving for his own holders. "The all-cash transaction delivers higher value to our shareholders through lower total cost consideration," he said ^[17]. Bank of America analysts wrote that the terms "could be received more favorably by investors as it removes the dilution overhang while preserving the strategic rationale" ^[16]. No new onsemi shares go to Synaptics investors ^[15].

The synergy target did not change. Onsemi still expects at least $200 million a year in run-rate synergies ^[8], about 3.5% of the $5.7 billion price ^[4][1]. Revenue synergies and moving part of Synaptics' production in-house come on top, and they start contributing only after the first 18 months post-close ^[9]. Against a close expected by mid-2027 ^[11], that puts the insourcing money at around the end of 2028 at the earliest ^[5]. For the first year and a half, onsemi's case rests on the cost target and the financing.

A counterbid is the clearest way this turns out differently, and the market is pricing it as unlikely. A 14% gain on Friday ^[13] takes a roughly $106 stock to about $121, some $2 under the cash price on rounded figures ^[6]. If Synaptics trades above $123 before its shareholders vote ^[11], the market expects a higher offer and this view is wrong.
