SUPPLEMENT TO PROXY STATEMENT
FOR THE ANNUAL MEETING OF STOCKHOLDERS
TO BE HELD ON JUNE 17, 2026
This proxy statement supplement (this “Supplement”), dated May 15, 2026, supplements and amends the proxy statement filed with the Securities and Exchange Commission on April 28, 2026 (the “Proxy Statement”) relating to the proxies being solicited by the Board of Directors (the “Board”) of Ouster, Inc., a Delaware corporation (the “Company” and “we,” “us” or “our”), in connection with our 2026 Annual Meeting of Stockholders to be held on Wednesday, June 17, 2026. This Supplement should be read together with the Proxy Statement. Other than as set forth below, no changes have been made to the Proxy Statement.
Engagement of Proxy Solicitor
We have engaged Alliance Advisors, LLC, an independent proxy solicitation firm, to assist in soliciting proxies on our behalf. The Company has agreed to pay a fee of $10,000, plus costs and expenses, for these and related services.
Expenses and Manner of Solicitation
As noted in the Proxy Statement, the Company will bear the expense of soliciting proxies by the Board. In addition to the use of mail, proxies may be solicited by personal interview, telephone, e-mail and facsimile by our directors, officers and other employees who will not be specially compensated for these services. We will also request that brokers, nominees, custodians and other fiduciaries forward soliciting materials to the beneficial owners of shares held by the brokers, nominees, custodians and other fiduciaries. We will reimburse these persons for their reasonable expenses in connection with these activities.
