[Synaptics](https://www.bullished.co/tag/syna/) said in a [supplemental proxy filing](https://www.sec.gov/Archives/edgar/data/0000817720/000114036126039984/ny20081083x3%5Fdefa14a.htm?ref=bullished.co) filed Monday that its definitive proxy statement was first mailed to stockholders on or about October 19, 2026\. The document concerns the pending acquisition of Synaptics by ON Semiconductor Corporation.

## What the filing shows

The filing is short. It reproduces only the cover page of the definitive proxy statement, the full document that lays out what stockholders are being asked to consider.

The cover page identifies the transaction as the pending acquisition of Synaptics by ON Semiconductor.

## What it changes for holders

The mailing starts the stockholder-vote process on the deal. If you own Synaptics shares, the full proxy statement is now the document to read.

Synaptics shares closed at $117.18 on Friday, down about 0.3% from $117.55 the session before, according to market data. That close came before the mailing was disclosed Monday. Market capitalization was $4.7 billion in market data as of Monday morning.

The deal remains pending, and the full proxy statement mailed to stockholders is where its terms and the vote are set out.
