Subject: Announcement: Proposed acquisition by onsemi

Team #OneSynaptics,

I’m excited to share an important milestone in Synaptics’ journey.

Today, we announced (https://www.globenewswire.com/news-release/2026/06/25/3317941/0/en/onsemi-to-acquire-synaptics-to-enable-the-next-generation-of-intelligent-systems-for-physical-ai.html) that Synaptics has entered into an agreement to be acquired by onsemi, a global leader in intelligent power and sensing technologies, in an all-stock transaction.

This combination brings together four decades of innovation at Synaptics with onsemi’s deep history in semiconductors to create a stronger company with enhanced scale. Since our founding, Synaptics has consistently evolved with the markets by anticipating technology shifts and capturing new opportunities. This transaction represents an important next step in accelerating our growth in Edge AI and Physical AI.

I want to begin by sincerely thanking the entire Synaptics team. Your hard work, innovation, and dedication have made this milestone possible.

Accelerating Our Growth

At its core, this transaction is about growth, scale, and opportunity.

onsemi and Synaptics share a common vision of delivering intelligent system solutions for customers. By combining Synaptics’ differentiated Edge AI compute franchise and strong portfolio of human-machine interface and wireless connectivity solutions with onsemi’s leadership in intelligent power and sensing, we will offer customers integrated solutions and development platforms across every layer of the Edge AI stack, deepening customer engagement and expanding across a greater total addressable market.

A key advantage of this combination is scale. onsemi’s extensive industrial distribution network, global customer relationships, and manufacturing capabilities will help accelerate our growth and enhance profitability. While Synaptics had already begun investing to expand sales and distribution reach, achieving comparable scale independently would have required considerable time and resources.

Just as importantly, this combination creates additional opportunities for our employees. Joining a large organization often brings expanded career pathways, greater organizational resources and capabilities, and increased opportunities to innovate.

What Happens Next

Today’s announcement does not change our day-to-day responsibilities or reporting structure. We remain focused on executing our strategy, delivering for our customers, and advancing our product roadmaps.

 We expect the transaction to close in mid-2027, subject to approval by Synaptics shareholders, the receipt of required regulatory approvals, and other customary closing conditions. Until then, onsemi and Synaptics will continue to operate as separate, independent companies.

To discuss today’s announcement, we will host two All-Hands meetings. As tomorrow is an Unplugged Day and we want to respect the opportunity for our teams to disconnect, rest, and recharge, we are holding these early next week at the following times:

Please join whichever session is most convenient for your time zone. Calendar details will follow shortly.

We have also attached an FAQ addressing many of the questions you may have. While we may not have all the answers immediately, we are committed to being transparent and timely in our communications.

Thank you again for your continued focus and commitment to Synaptics. The opportunities ahead are exciting, and I am confident our best days are still ahead.

Best regards,
