Dolby Laboratories, Inc.

We are furnishing proxy materials to our stockholders primarily via the internet. On or about December 16, 2025, we mailed to our stockholders a Notice of Internet Availability of Proxy Materials containing instructions on how to access our proxy materials, including our Proxy Statement and our 2025 Annual Report. The Notice of Internet Availability of Proxy Materials also provides information on how to access your voting instructions to be able to vote through the internet or by telephone. Other stockholders, in accordance with their prior requests, have receivede-mail notification of how to access our proxy materials and vote via the internet, or have been mailed paper copies of our proxy materials and a proxy card or voting instruction form.

Internet distribution of our proxy materials helps to expedite receipt by stockholders, lowers the cost of the Annual Meeting and conserves natural resources. However, if you would prefer to receive printed proxy materials, please follow the instructions included in the Notice of Internet Availability of Proxy Materials. If you have previously elected to receive our proxy materials electronically, you will continue to receive these materials viae-mail unless you elect otherwise.
