Message from our Chief Executive Officer

Dear Stockholder:

Since our 2021 IPO, Arteris has delivered consistent growth in terms of revenue, customer design starts and royalties. In 2025, we reached $70.6M in revenue with our customers shipping over 4 billion System-on-Chips (“SoC”) containing Arteris system IP technology. We also are experiencing growth in our SoC integration automation products.

On behalf of this company and its directors, I thank you, our stockholders, for your continued support of the company’s commitment to provide leading semiconductor SoC technology and reliable support to our customers around the world.

The increasing complexity of modern SoC-type semiconductors and the shift towards systems that make intelligent decisions rather than simply process data, continues to elevate the importance of system IP as a key component to SoC creation. As a result, Arteris’ growth opportunities are expanding in applications and across markets, including automotive, artificial intelligence and machine learning, 5G communications, data centers, edge computing, enterprise and consumer electronics. We are also seeing continued momentum in our SoC integration automation products and encouraged by our microcontroller system IP business. Further, in January 2026, we expanded our product portfolio through the acquisition of Cycuity, Inc., a leader in semiconductor cybersecurity verification technology. The addition of Cycuity strengthens our ability to address the growing need for secureon-chip data movement as cyber threats increasingly target the hardware layer across applications from AI data centers to edge devices.

With a strong balance sheet, proven products, and atop-notch global customer support organization, we believe we are well positioned to take advantage of market opportunities while navigating ongoing macroeconomic and geopolitical uncertainty. The Arteris IP team remains focused on executing our strategy in our market segments and strengthening our leadership in system IP.

With this progress in mind, I am pleased to invite you to attend the 2026 Annual Meeting of Stockholders (the “Annual Meeting”) of Arteris, Inc., which will be held online at www.proxydocs.com/AIP, on June 2, 2026 at 8:30 a.m. Pacific Time/11:30 a.m. Eastern Time. You must register to attend the meeting online at www.proxydocs.com/AIP no later than June 1, 2026 at 2:00 p.m. Pacific Time/5:00 p.m. Eastern Time.

The attached Notice of Annual Meeting of Stockholders and Proxy Statement contain details of the business to be conducted at the Annual Meeting.

Whether or not you attend the Annual Meeting online, it is important that your shares be represented and voted at the meeting. Therefore, I urge you to promptly vote and submit your proxy via the Internet, by phone or by mail.
