SUMMARY OF CODE OF CONDUCT CHANGES IN ACCORDANCE WITH ITEM 406(B) OF REGULATION S-K

Effective April 27, 2021, Synaptics Incorporated (“Synaptics”) revised our Code of Conduct (the “Code”). We updated the Code to make it more user-friendly and align it with our policies, practices, and values. The Code applies to all Synaptics directors, officers, and employees. The revisions to the Code relating to elements of the “Code of Ethics” definition in Item 406(b) of the SEC’s Regulation SK are: (i) we added references to key company policies that provide more detail on certain provisions of the Code; (ii) we added detail regarding antitrust compliance, political influence and payments to government officials, conflicts of interest, record-keeping, use of company assets, external communications, and reporting of violations; (iii) we added sections on international trade compliance, privacy, dealing with suppliers, and the use of social media; and (iv) we made other revisions that align the Code with current Synaptics policies, practices, and values.

The Code is available in the “Corporate Governance” section of the “Investor Relations” page of Synaptics’ investor relations website at https://investor.synaptics.com/corporate-governance. Synaptics’ “Code of Ethics for the CEO and Senior Financial Officers” is unchanged and available at the same website address.
