As previously disclosed in a Current Report on Form 8-K filed by Nuburu, Inc. (the “Company”) with the Securities and Exchange Commission (the “SEC”) on May 10, 2023, Dr. Ake Almgren notified the Company on May 9, 2023 of his resignation as a member of the Board of Directors (the “Board”) effective as of May 19, 2023 (the “Resignation Date”). Dr. Almgren has been serving as a member of the Board’s audit committee and nominating and corporate governance committee. Dr. Almgren resigned for personal reasons and not as the result of any disagreement with the Company on any matter relating to the Company’s operations, policies or practices.

Director Reclassification

On May 15, 2023, in order to achieve an equal apportionment of membership among the three director classes of the Board, Ron Nicol tendered his resignation as a Class II director, effective upon the Board reappointing Mr. Nicol as a Class I director. On May 15, 2023, the Board reappointed Mr. Nicol as a Class I director effective as of the Resignation Date. Class I directors serve until the 2023 Annual Meeting of Stockholders and Class II directors serve until the 2024 Annual Meeting of Stockholders. The resignation and reappointment of Mr. Nicol was effected solely for the purpose of achieving an equal apportionment of membership among the Board’s three classes of directors, and for all other purposes, Mr. Nicol’s service on the Board is deemed to have continued uninterrupted.

Mr. Nicol will continue to serve as the chair of the Board and will continue to serve on the Board’s audit committee and compensation committee. There are no changes or impacts to any of Mr. Nicol’s compensation arrangements or equity awards as a result of his resignation as a Class II director and reappointment as a Class I director.

There are no arrangements or understandings between Mr. Nicol and any other person pursuant to which Mr. Nicol was selected as a director.

Mr. Nicol will continue to receive director compensation as described in the “Direction Compensation” section of the Company’s definitive proxy statement filed with the SEC on April 21, 2023 (the “2023 Proxy Statement”), which disclosure is incorporated herein by reference. Mr. Nicol previously entered into an indemnification agreement with the Company, the form of which was filed as Exhibit 10.29 to the Company’s Annual Report on Form 10-K, filed by the Company with the SEC on March 31, 2023, and which remains in effect as of the date hereof.

Certain transactions between the Company and Mr. Nicol required to be disclosed pursuant to Item 404(a) of Regulation S-K are described in the “Certain Relationships and Related Party Transactions” section of the 2023 Proxy Statement, which disclosure is incorporated herein by reference.
