Item 1.01 Entry into a Material Definitive Agreement

Head of Terms with SunCubes S.r.l.

On June 4, 2026, Nuburu, Inc. (the "Company") entered into a binding Head of Terms (the "HoT") with SunCubes S.r.l. ("SunCubes"), the individual founders of SunCubes (the "Founders"), Infratech Accelerator S.r.l. ("CrossConnect"), RoboIT S.r.l. ("RoboIT") and Pariter Partners S.r.l. ("Pariter, and, with CrossConnect and RoboIT, the "Current Investors") (collectively, the "Parties").

SunCubes is an Italian developer of laser-based wireless power transmission, beam-control, pointing, tracking and safety technologies.

The Current Investors are venture capital special purpose vehicles affiliated with CDP Venture Capital SGR S.p.A. ("CDP Venture Capital"). CDP Venture Capital is an Italian venture capital asset manager owned 70% by CDP Equity S.p.A. ("CDP Equity") and 30% by Invitalia S.p.A. CDP Equity, which is a holding company of the Cassa Depositi e Prestiti S.p.A. ("CDP") group. CDP is Italy's National Promotional Institution and a joint-stock company under public control. CDP's majority shareholder is the Italian Ministry of Economy and Finance, which holds 82.77% of CDP, while foundations of banking origin hold the remaining 17.23%. CDP, CDP Equity, CDP Venture Capital and the Italian Ministry of Economy and Finance are not direct parties to the HoT.

Under the HoT, the Parties desire to have (i) the Company and SunCubes enter into an industrial, commercial and technological cooperation framework for the development and industrialization of a vehicle-integrated directed-energy "Laser Arm" system (the "Industrial Cooperation Framework") and (ii) the Company contribute up to €1,000,000 to, and acquire a minority stake in, SunCubes (the "Investment" and, together with the Industrial Cooperation Framework, the "Transaction").

Required Clearances

Within 60 days of the execution of the HoT, the Parties must enter into long-form agreements (the "Definitive Agreements") governing the terms and conditions of the Transaction. The Industrial Cooperation Framework and the Investment are each subject to (i) receipt of clearance, approval or consent, whether explicit or obtained after the expiration of the applicable waiting period, from the Italian government under the Golden Power Regulations or a declaration of lack of jurisdiction by such authority (the "GP Clearance"); and (ii) the receipt by SunCubes of an export-control or dual-use license or approval required in connection with the Transaction (the "Export-Control License Clearance" and, with the GP Clearance, the "Clearances"), provided that such clearance will be deemed to be obtained if granted by the United States, Italy or Ukraine (excluding Russian-occupied territories). If either of the GP Clearance or the Export-Control License Clearance is not obtained by December 30, 2026, the Definitive Agreements will automatically terminate; provided, however, that if the GP Clearance is granted solely in relation to the Industrial Cooperation Framework, the Parties will negotiate to implement the Industrial Cooperation Framework through a joint venture (or other structure) and any amounts paid by the Company to SunCubes would be allocated to such joint venture. If the Clearances are obtained but the Investment is not completed for any reason, the Industrial Cooperation Framework will remain in full force and effect between the Parties.

Investment in SunCubes

The Company, or its designated subsidiary, will make an advance payment as a capital contribution of (i) €250,000 upon the execution of the Definitive Agreements and (ii) €750,000 upon receipt of the Clearances (the "Advance Payments"). The conversion of the Advance Payments into an ownership stake in SunCubes (the "Capital Increase") requires approval of SunCubes' equity holders and such ownership stake will include certain anti-dilution protections. Other investors may also make an investment in SunCubes at the same time and on similar terms as the Company's Capital Increase.

The Current Investors have entered into an agreement for subscription for future equity ("SAFE") with SunCubes. The Capital Increase by the Company is subject to the occurrence by December 31, 2026 of the earliest of (i) the full conversion into SunCubes corporate capital of the SAFE investment by the Current Investors upon the occurrence of an undertaking by third-party investors to make a capital increase of at least €1,230,000, or (ii) the discretionary conversion into SunCubes corporate capital of the SAFE investment carried out by the Current Investors (the "Capital Increase Condition"). If the Capital Increase Condition is met before either Clearance is obtained, such Capital Increase will occur following the receipt of the Clearances. If the required Clearances or Capital Increase Condition are not met, SunCube will repay the Advance Payments to the Company by March 31, 2027. Upon the attainment of the Clearances, the Company may designate an observer to attend meetings of, and receive materials distributed to, the Board of Directors of SunCubes.

Industrial Cooperation Framework

As part of the Industrial Cooperation Framework, SunCubes will grant to the Company and entities controlled by the Company (the "Permitted Users") a non-exclusive, fully paid-up license to certain SunCubes background intellectual property ("IP") rights in a specific field and territories, including the right to use, modify and adapt products supplied by SunCubes embedding such IP rights; integrate them into present and future Company systems; assemble, test and validate products supplied by SunCubes; commercialize, market, distribute and sell products embedding SunCubes technologies; import and export such products; and provide maintenance and support for such products. If new IP rights arise from the Company's integration of products supplied by SunCubes, the Company will retain the rights thereto and grant a non-exclusive, fully paid-up license to SunCubes in certain fields. For new intellectual property rights commissioned by the Company for the development of a high-power laser arm, such rights will remain the exclusive property of the Company or be jointly owned by the parties, as specified in the Definitive Agreements. SunCubes will not use the Company's background IP rights for the realization, construction or distribution of laser arm products. The HoT also specifies the ownership and licensing of improvements, enhancements, modifications, future versions, releases or technical evolutions developed by SunCubes, the Company or jointly.

The Parties agreed to cooperate to create a research and development hub in Milan, Italy for optical engineering and beam-control development, laser source integration, thermal management optimization, AI-assisted engagement logic, and system validation and testing. They agreed that directed-energy systems may be industrialized at Italian facilities, including Lyocon S.r.l. ("Lyocon") in Vigevano or Tekne S.p.A. ("Tekne") in Ortona, for laser arm assembly, integration with vehicle platforms and EU/NATO compliant export preparation. Lyocon is a wholly owned subsidiary of the Company and the Company, subject to obtaining a pending GP Clearance, will own 70% of Tekne. SunCubes agrees to designate the Company as preferred Industrial Integration Partner for high-power vehicle-mounted laser arm systems, subject to the Company's fulfillment of SunCubes' technical, cost and quality requirements. SunCubes agrees not to grant exclusivity in the segment to direct competitors of the Company during the cooperation term. The Company will have the right to designate SunCubes as an Original Equipment Manufacturer for the products developed by SunCubes with the Company's right to market, distribute or sell said products under the Company's trademarks or without any trademark.

The Company will have the non-exclusive right to commercialize, sell and distribute the products supplied by SunCubes, pursuant to the terms and conditions of a distribution agreement to be entered into by the Company and SunCubes. SunCubes agrees to offer to the Company any products or by-products requested by the Company at a price not higher than the lowest price at which SunCubes offers comparable products to other clients. If SunCubes' margin allows for a greater discount in favor of the Company, it will apply a further discount not greater than 5% lower than the lowest price at which SunCubes offers comparable products. Nothing in the HoT grants SunCubes any exclusive right to supply products to the Company or imposes on the Company any obligation to purchase, use, license or otherwise adopt any intellectual property, technology or solutions provided by SunCubes.

Additional Agreements by SunCubes

SunCubes agrees that, while CrossConnect or RoboIT are equity holders of SunCubes, it will not engage in activities related to the production of anti-personnel mines, cluster munitions and submunitions or engage in technological research, manufacture, sale or transfer or possession of cluster munitions and submunitions. If SunCubes engages in any such activities, CrossConnect and RoboIT have the right to withdraw from the HoT and from SunCubes.

The Definitive Agreements may contain terms that differ from those described in the HoT, and there can be no assurance that the parties will enter into Definitive Agreements, obtain the required Clearances or consummate the Transaction within the expected time frame or at all.
