Householding of Proxy Materials

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for proxy statements, annual reports, or notices of internet availability of proxy materials with respect to two or more stockholders sharing the same address by delivering a single proxy statement, annual report, or notice of internet availability of proxy materials addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders and cost savings for companies.

Brokers with account holders who are Company stockholders may be “householding” our proxy materials. A single proxy statement, annual report, or notice of internet availability of proxy materials may be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that it will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you notify your broker or the Company that you no longer wish to participate in “householding.”

If, at any time, you no longer wish to participate in “householding” and would prefer to receive a separate proxy statement, annual report, or notice of internet availability of proxy materials, you may (1) notify your broker or (2) direct your written request to: Investor Relations, Nuburu, Inc., 7442 S. Tucson Way, Suite 130, Centennial, CO 80112. Stockholders who currently receive multiple copies of the proxy statement, annual report, or notice of internet availability of proxy materials at their address and would like to request “householding” of their communications should contact their broker. In addition, the Company will promptly deliver, upon written or oral request to the address or telephone number above, a separate copy of the proxy statement, annual report, or notice of internet availability of proxy materials promptly to any stockholder at a shared address to which a single copy of the documents was delivered.

Other Matters

As of the date of this Proxy Statement, the Board does not intend to present any matters other than those described herein at the Annual Meeting and is unaware of any matters to be presented by other parties. If other matters are properly brought before the meeting for action by the stockholders, proxies will be voted in accordance with the recommendation of the Board or, in the absence of such a recommendation, in accordance with the judgment of the proxy holder.

Stockholder Proposals for Director Nominations for 2026 Annual Meeting

If a stockholder would like us to consider including a proposal in our proxy statement for our 2026 annual meeting pursuant to Rule 14a‑8 of the Exchange Act, then the proposal must be received by our corporate secretary at our principal executive offices on or before February 10, 2026. In addition, stockholder proposals must comply with the requirements of Rule 14a‑8 regarding the inclusion of stockholder proposals in company‑sponsored proxy materials. Proposals should be addressed to:

Attention: Corporate Secretary

7442 S. Tucson Way, Suite 130, Centennial, CO 80112

Our bylaws also establish an advance notice procedure for stockholders who wish to present a proposal or nominate a director at an annual meeting, but do not seek to include the proposal or director nominee in our proxy statement. In order to be properly brought before our 2026 annual meeting, the stockholder must provide timely written notice to our corporate secretary, at our principal executive offices, and any such proposal or nomination must constitute a proper matter for stockholder action. The written notice must contain the information specified in our bylaws. To be timely, a stockholder’s written notice must be received by our corporate secretary at our principal executive offices:

•

no earlier than 8:00 a.m., Mountain Time, on March 11, 2026, and

•

no later than 5:00 p.m., Mountain Time, on April 10, 2026.

In the event that we hold our 2026 annual meeting more than 30 days before or more than 70 days after the one-year anniversary of this year’s annual meeting, then such written notice must be received by our corporate secretary at our principal executive offices:

•

no earlier than 8:00 a.m., Mountain Time, on the 120th day prior to the day of our 2026 annual meeting, and

•

no later than 5:00 p.m., Mountain Time, on the later of (i) the 90th day prior to the day of our 2026 annual meeting and (ii) the 10th day following the day on which public announcement of the date of the annual meeting is first made by us.

If a stockholder who has notified us of his, her or its intention to present a proposal at an annual meeting of stockholders does not appear to present his, her or its proposal at such annual meeting, then we are not required to present the proposal for a vote at such annual meeting.

Universal Proxy Rules

In addition to complying with the advance notice provisions of our bylaws, stockholders who intend to solicit proxies in support of director nominees other than the Company’s nominees must provide timely notice that sets forth the information required by and otherwise complies with Rule 14a-19 under the Exchange Act, which must be received no later than 60 calendar days prior to the anniversary of the previous year’s annual meeting, which will be May 10, 2026 (except that, if the date of the meeting has changed by more than 30 days from such anniversary date, then notice must be provided by the later of 60 days prior to the date of the annual meeting or the 10th day following the day on which public announcement of the date of the annual meeting is first made by the Company).
