Offering Common Warrants to purchase shares of Common Stock. The warrants may be exercised in whole or in part for cash or, in certain circumstances, on a cashless basis, subject to certain beneficial ownership limitations. Net proceeds from the February 2026 Offering were first allocated to the liability-classified February 2026 Offering Pre-Funded Warrants and February 2026 Offering Common Warrants at their aggregate issuance date fair value of $18,918,964, which was greater than the proceeds received from the February 2026 Offering of $11,994,929, therefore the Company recorded a loss on issuance of warrants on the condensed consolidated statement of operations and comprehensive loss of $6,924,035 for the six months ended June 30, 2026, with no residual net proceeds allocated to the Common Stock and February 2026 Offering Placement Agent Warrants. Changes in the fair value of the February 2026 Offering Pre-Funded Warrants and February 2026 Offering Common Warrants are included within change in fair value of warrant liabilities in the condensed consolidated statement of operations and comprehensive loss for the six months ended June 30, 2026.

On September 16, 2025, in connection with the 2025 Offering as described in Note 11, the Company issued 25,260,605 liability-classified 2025 Offering Common Stock Warrants to purchase shares of Common Stock. Each 2025 Offering Common Stock Warrant is immediately exercisable, has an exercise price of $0.8553 per share, subject to adjustment upon certain events, and expires on September 16, 2030. The warrants may be exercised in whole or in part for cash or, in certain circumstances, on a cashless basis, subject to certain beneficial ownership limitations. Net proceeds from the 2025 Offering were first allocated to the liability-classified 2025 Offering Common Stock Warrants at their aggregate issuance date fair value of $20,747,899, which was greater than the net proceeds received from the 2025 Offering of $10,744,346, therefore the Company recorded a loss on issuance of warrants on the condensed consolidated statement of operations and comprehensive loss of $8,756,303 in the third quarter of 2025, with no residual net proceeds allocated to the Common Stock and 2025 Offering Pre-Funded Warrants.

Junior Note Warrants

In connection with the issuance of certain Junior Notes during 2023, which were extinguished in early 2025 as discussed in Note 10, the Company issued the Junior Note Warrants to purchase up to 110,221 shares of Common Stock. The Junior Note Warrants currently outstanding have an exercise price equal to $24.95 per share (subject to adjustment per the Junior Note Purchase Agreements) and expire on December 6, 2028. The Junior Note Purchase Agreements provided for the issuance of additional warrants if the related Junior Notes remained outstanding for specified periods following issuance, including at six and nine months, and as a portion of the Junior Notes were outstanding at each of these measurement dates in 2024, the Company was required to issue 61,988 additional warrants pursuant to the Junior Note Purchase Agreements during 2024.

Public Warrants

In connection with the closing of the Business Combination, Nuburu assumed the 83,722 Public Warrants outstanding on the date of closing, all of which were outstanding as of June 30, 2026. However, on December 12, 2023, the NYSE notified the Company and publicly announced that the NYSE had determined to (a) commence proceedings to delist the Company’s Public Warrants, each whole Public Warrant exercisable to purchase one share of Common Stock at a price of $2,295.40 per share, and listed to trade on the NYSE under the symbol “BURU WS”, and (b) immediately suspend trading in the Public Warrants due to “abnormally low” trading price levels. As such, the Public Warrants were determined to have no value in the financial statements as of June 30, 2026 and 2025.

Equity-Classified Common Stock Warrants

Q2 2026 Indigo Pre-Funded Warrants

During the three months ended June 30, 2026, the Company issued pre-funded warrants to purchase an aggregate of 28,832,411 shares of Common Stock (collectively, the "Q2 2026 Indigo Pre-Funded Warrants") to Indigo Capital, in multiple tranches, in exchange for the extinguishment of an aggregate of 337,849 shares of our Series A Preferred Stock. The exchange was accounted for as an extinguishment of preferred stock, with the carrying value of the Series A Preferred Stock of $3,378,490 derecognized and the fair value of the Q2 2026 Indigo Pre-Funded Warrants of $4,951,802 recognized within additional paid-in capital, as the Q2 2026 Indigo Pre-Funded Warrants were determined to be equity-classified, with the difference of $1,573,312 recognized as a deemed dividend reflected as an adjustment to net loss available to common stockholders for the three and six months ended June 30, 2026. Because the Q2 2026 Indigo Pre-Funded Warrants had a nominal exercise price per share and were immediately exercisable, their fair value at issuance was determined based on the closing price of Common Stock on each issuance date, less the exercise price.

In July 2026, the Company issued a pre-funded warrant to purchase 12,589,084 shares of Common Stock to Indigo Capital in exchange for the extinguishment of 109,097 shares of our Series A Preferred Stock.

February 2026 Offering Placement Agent Warrants

On February 17, 2026, in connection with the February 2026 Offering as described in Note 11, the Company issued to the February 2026 Placement Agent or its designees 437,239 February 2026 Offering Placement Agent Warrants to purchase shares of Common Stock. The February 2026 Offering Placement Agent Warrants have an exercise price of $0.6861 per share, are exercisable beginning six months from the date of issuance and expire on the five-year anniversary of the closing date of the February 2026 Offering. The warrants are exercisable in whole or in part for cash or, in certain circumstances, on a cashless basis, subject to certain beneficial ownership limitations. The issuance date

fair value of the February 2026 Offering Placement Agent Warrants of $185,018 was treated as an equity-issuance cost and reduction in additional-paid in capital, and was estimated using the Black Scholes valuation model, a Level 3 valuation, with the following assumptions:

Indigo Pre-Funded Warrants

On February 6, 2026, we entered into an exchange agreement with Indigo Capital, pursuant to which we agreed to issue 11,176,650 Indigo Pre-Funded Warrants in exchange for the extinguishment of 844,938 shares of our Series A Preferred Stock. The exchange was accounted for as an extinguishment of preferred stock, with the carrying value of the Series A Preferred Stock of $8,449,380 derecognized and the fair value of the Indigo Pre-Funded Warrants of $8,923,438 recognized within additional paid-in capital, as the Indigo Pre-Funded Warrants were determined to be equity-classified, with the difference of $474,058 recognized as a deemed dividend reflected as an adjustment to net loss available to common stockholders. Because the Indigo Pre-Funded Warrants had a nominal exercise price per share and were immediately exercisable, their fair value at issuance was determined based on the closing price of the Common Stock on February 6, 2026, less the exercise price.

December 2025 YA Warrants

In connection with the issuance of the December 2025 YA Debenture, as further described in Note 10, the Company issued warrants to purchase an aggregate of 46,092,185 shares of Common Stock consisting of (i) warrants exercisable for 16,032,065 shares at an exercise price of $0.05 per share (the "December 2025 $0.05 YA Warrants"), (ii) warrants exercisable for 20,040,081 shares at an exercise price of $1.25 per share (the "December 2025 $1.25 YA Warrants"), (iii) warrants exercisable for 5,010,021 shares at an exercise price of $1.871 per share (the "December 2025 $1.871 YA Warrants") and (iv) warrants exercisable for 5,010,021 shares at an exercise price of $2.35 per share (the "December 2025 $2.35 YA Warrants") (collectively, the "December 2025 YA Warrants"). The December 2025 YA Warrants are exercisable anytime from issuance through the expiration date of December 17, 2030.

Issuance of warrant shares in excess of 19.99% of the Company’s outstanding Common Stock is subject to stockholder approval, which the Company received at its special meeting of stockholders held on March 12, 2026. Certain of the December 2025 YA Warrants may be exercised on a cashless basis if the related shares are not registered for resale. The Company may require cash exercise of certain of the December 2025 YA Warrants upon satisfaction of specified market-based and registration conditions, subject to volume limitations. The December 2025 YA Warrants contain customary anti-dilution and fundamental transaction provisions designed to preserve the holder’s economic interests, including adjustments for stock splits, dividends and similar events. Prior to exercise, the December 2025 YA Warrants do not confer voting or dividend rights, but permit participation in certain distributions on an as-converted basis, subject to beneficial ownership limitations. The December 2025 YA Warrants are transferable subject to applicable securities laws and include customary remedies for failure to timely deliver shares upon exercise.

The Company entered into a registration rights agreement requiring the Company to file a registration statement covering the resale of the warrant shares and, subject to certain exceptions, restricting the Company from filing other registration statements until such shares are registered. The December 2025 YA Warrants were registered by the Company pursuant to a Registration Statement on Form S-1 filed with the SEC on December 23, 2025, under the Securities Act (File No. 333-292426), and declared effective by the SEC on January 7, 2026.

As further described in Note 10, as the issuance of the December 2025 YA Debenture and the December 2025 YA Warrants involved the issuance of both debt and equity instruments, and the fair value of the December 2025 YA Debenture at inception was greater than the net proceeds received for the issuance of the December 2025 YA Debenture and the December 2025 YA Warrants, no value was ascribed to the December 2025 YA Warrants.

As discussed above, net proceeds from the 2025 Offering were first allocated to the liability-classified 2025 Offering Common Stock Warrants at their aggregate issuance date fair value, and no residual proceeds were allocated to the Common Stock and 2025 Offering Pre-Funded Warrants. The issuance date fair value of the 2025 Offering Placement Agent Warrants of

June 2023 Senior Note Warrants

In connection with the issuance of Senior Notes, which were extinguished in early 2025 as discussed in Note 10, the Company issued the Senior Note Warrants to purchase up to 57,710 shares of Common Stock pursuant to the June 12, 2023 Senior Note Purchase Agreement and 9,467 shares of Common Stock pursuant to the June 16, 2023 Senior Note Purchase Agreement.

Pre-Funded Warrants

On May 1, 2024, the Company entered into a Pre-Funded Warrant Purchase Program (the “Program”) with strategic investors, pursuant to which from time-to-time the Company could sell and the investors could acquire pre-funded warrants, up to a total purchase price to the Company equal to $15,000,000. The exercise price for pre-funded warrants is substantially paid by the purchaser at closing and, as a result, such warrants may be exercised in the future with a nominal exercise price payment. Investors also received a warrant to acquire the same number of shares covered by the pre-funded warrant for a purchase price equal to 150% of the relevant pre-funded warrant purchase price exercisable for a period of 5 years. Each specific transaction was entered into on terms agreed by the parties; provided however, that in no case would the purchase price per share be less than 110% of the closing price per share of Common Stock on the trading day immediately preceding the date of purchase. Contemporaneously with the acquisition of pre-funded warrants, the investors could also voluntarily convert outstanding notes previously issued by the Company; provided that such transactions, as a whole, could not result in an effective direct or indirect discount to market price to the investors of greater than 30%. During 2024, the Company issued 167,759 pre-funded warrants for total cash proceeds of $2,139,866 in pre-funded warrants pursuant to the Program (the "Pre-Funded Warrants").

Pre-Funded Warrants Modification — In February 2025, in connection with the Liqueous Settlement Agreement, as amended, the Company agreed to (i) modify 133,349 outstanding equity-classified Pre-Funded Warrants issued in connection with the Program during 2024, resulting in the issuance of 730,946 equity-classified pre-funded warrants outstanding immediately after the modification exercisable into Common Stock and (ii) modify the remaining 34,411 outstanding equity-classified Pre-Funded Warrants issued in connection with the Program during 2024, resulting in 1,875,930 pre-funded warrants outstanding immediately after the modification that were concurrently exercised into 1,875,930 shares of Common Stock for no additional cash consideration, as the modified pre-funded warrants had a nominal exercise price (the "Pre-Funded Warrants Modification"). As a result of the Liqueous Settlement Agreement, there will not be further issuances under the Program.

The Company accounted for the Pre-Funded Warrants Modification in accordance with ASC 815, Derivatives and Hedging, where the effect of a modification shall be measured as the difference between the fair value of the modified warrant and the fair value of the original warrant immediately before its terms are modified, with each measured on the modification date. As a result of the Pre-Funded Warrants Modification, which was not contemplated as a result of an equity or debt financing, but rather, as a settlement of any claims between the parties related to non-performance of obligations under certain previous agreements executed between the Company and Liqueous, the Company recorded (i) an increase to equity of $3,076,380, and a corresponding deemed dividend, related to the incremental fair value of the modified Pre-Funded Warrants over the fair value of the original Pre-Funded Warrants, each measured on the modification date and (ii) a loss on settlement of an aggregate $2,026,380, which represents the incremental fair value of the modified Pre-Funded Warrants over the fair value of the original Pre-Funded Warrants, each measured on the modification date, less cash received or receivable related to the Liqueous Settlement Agreement of $1,050,000. The loss on settlement is recorded in loss on extinguishment of debt on the condensed consolidated statement of operations and comprehensive loss during the three months ended March 31, 2025.
