BACKGROUND AND ORGANIZATION

BACKGROUND AND ORGANIZATION	6 Months Ended
	Jun. 30, 2023
Organization, Consolidation and Presentation of Financial Statements [Abstract]
BACKGROUND AND ORGANIZATION	NOTE 1. BACKGROUND AND ORGANIZATION Nuburu, Inc. (“Nuburu” or the “Company”) and its wholly-owned subsidiary Nuburu Subsidiary, Inc., is a leading innovator in high-power, high-brightness blue laser technology that is focused on bringing breakthrough improvements to a broad range of high value applications including welding and 3D printing. Nuburu was originally incorporated in Delaware on July 21, 2020 under the name Tailwind Acquisition Corp. (“Tailwind”) as a special purpose acquisition company, formed for the purpose of effecting an initial business combination with one or more target businesses. On September 9, 2020 (the “IPO Closing Date”), we consummated our initial public offering (the “IPO”). On January 31, 2023, we consummated a business combination with Nuburu Subsidiary, Inc. f/k/a Nuburu, Inc. (“Legacy Nuburu”), a privately held operating company which merged into our subsidiary Compass Merger Sub, Inc. (the “Business Combination”) and changed our name to “Nuburu, Inc.,” and we became the owner, directly or indirectly, of all of the equity interests of Nuburu Subsidiary, Inc. and its subsidiaries. In light of the fact that the Business Combination has closed and our ongoing business will be the business formerly operated by Legacy Nuburu, this business section primarily includes information regarding Legacy Nuburu’s business. Throughout the notes to the condensed consolidated financial statements, unless otherwise noted, the “Company,” “we,” “us” or “our” and similar terms refer to Legacy Nuburu prior to the consummation of the Business Combination, and Nuburu and its subsidiaries after the consummation of the Business Combination. Going Concern and Liquidity The Company devotes its efforts to business planning, research and development and raising capital. From inception through June 30, 2023, the Company has incurred operating losses and negative cash flows from operating activities. For the six months ended June 30, 2023 and 2022, the Company has incurred operating losses, including net losses of $ 10,874,229 and $ 6,183,345 , respectively. The Company has an accumulated deficit of $ 72,066,537 as of June 30, 2023, which factors raise substantial doubt about the Company's ability to continue as a going concern. The Company expects to continue to expand our operations, including by investing in manufacturing, sales and marketing, research and development and infrastructure to support our growth. The Company anticipates that we will incur net losses for the foreseeable future and, even if we increase our revenues, there is no guarantee that we will ever become profitable. Until we can generate sufficient revenue to cover our operating expenses, working capital, and capital expenditures, we will rely on funds raised from the closing of the Business Combination, from the $ 9,225,000 of Convertible Notes and Warrants issued in June 2023, from the $ 11,400,000 of Legacy Nuburu convertible notes (the "Company Notes") issued prior to the Closing, from the Lincoln Park Purchase Agreement pursuant to which Lincoln Park has agreed to purchase from the Company, at the sole discretion of the Company, up to $ 100,000,000 of Common Stock from time to time over a 48-month period. In accordance with the Lincoln Park Purchase Agreement, Lincoln Park has purchased, at the option of the Company, approximately $ 2,100,000 of Common Stock during the three months ended June 30, 2023. The Company plans to finance its operations with proceeds from the issuance and sale of equity securities or debt; however, there is no assurance that management's plans to obtain additional debt or equity financing will be successfully implemented or implemented on terms favorable to the Company. Certain Significant Risks and Uncertainties The Company’s current business activities consist of business planning, research and development efforts to design and develop high-power, high-brightness blue laser technology. The Company is subject to the risks associated with such activities, including the need to further develop its technology, its marketing, and distribution channels; further develop its supply chain and manufacturing; and hire additional management and other key personnel. Successful completion of the Company’s development program and, ultimately, the attainment of profitable operations are dependent upon future events, including its ability to access potential markets, and secure long-term financing. As of the date of issuance of the financial statements, the Company’s operations have not been significantly impacted by the COVID-19 pandemic, however, the Company continues to monitor the situation. While the Company’s results of operations, cash flows and financial condition could be negatively impacted, the extent of the impact cannot be reasonably estimated at this time. The impact of the Russian invasion of Ukraine and the related sanctions imposed by the United States and other countries on the Company’s financial condition, results of operations, and cash flows is also not determinable as of the date of these financial statements. The Company’s future results of operations involve a number of risks and uncertainties. Factors that could affect the Company’s future operating results and cause actual results to vary materially from expectations include, but are not limited to, rapid technological change, competition from substitute products and larger companies, protection of proprietary technology, ability to maintain distributor relationships and dependence on key individuals.

Principles of Consolidation The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary. All significant intercompany balances and transactions have been eliminated in consolidation. Emerging Growth Company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. Significant Accounting Policies The significant accounting policies used in preparation of these condensed consolidated financial statements are disclosed in the notes to consolidated financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022 filed with the SEC on March 31, 2023 and the audited financial statements of Legacy Nuburu for the years ended December 31, 2022 and 2021 included in the Amendment No. 1 to the Form 8-K filed with the SEC on March 31, 2023. The significant accounting policies have not changed significantly since those filings.

The other related events that occurred in connection with the Closing are summarized below: • Tailwind and the Tailwind Sponsor entered into a letter agreement (the “Sponsor Support and Forfeiture Agreement”), dated as of August 5, 2022 (as amended by the Amended and Restated Sponsor Support and Forfeiture Agreement, dated January 31, 2023). In connection with the Business Combination, the 8,355,393 Tailwind Sponsor Class B shares were forfeited other than 1,150,000 shares of Common Stock (of which, 150,000 shares were transferred to Nautilus Maser Fund, L.P. and 50,000 shares were transferred to Cohen & Company Capital Markets at Closing) and 650,000 shares of Series A preferred stock. Additionally, upon the Closing, the Sponsor cancelled the 9,700,000 Private Placement Warrants that were held by the Sponsor. • Tailwind, Legacy Nuburu and Lincoln Park entered into a purchase agreement pursuant to which Nuburu may direct Lincoln Park to purchase up to $ 100 million of Common Stock from time to time over a 48-month period, subject to certain limitations contained in the Lincoln Park Purchase Agreement. At the Closing, Nuburu issued 200,000 shares of Nuburu Common Stock to Lincoln Park. • Legacy Nuburu entered into an engagement letter with Anzu Partners on August 30, 2022 (the “Services Agreement”) relating to this arrangement pursuant to which Legacy Nuburu, in recognition of past Services, (i) agreed to pay $ 500,000 to Anzu Partners upon the closing of the Business Combination and (ii) issued a warrant with a strike price of $ 0.01 per share to Anzu Partners for 500,000 shares of Preferred Stock (the “Anzu Partners Warrant”). This warrant was exercised by Anzu Partners in connection with the Closing. After giving effect to the Business Combination as described above, the number of shares of Common Stock and Series A preferred stock issued and outstanding immediately following the consummation of the Business Combination was as follows: Common Shares Series A Tailwind public shares 316,188 — Tailwind Sponsor Class B shares 8,355,393 — Total shares of Tailwind common stock outstanding immediately prior to the Business Combination 8,671,581 — Less: forfeiture of the Tailwind Sponsor Class B Common Stock other than 1,150,000 shares of Common Stock and 650,000 shares of Series A Preferred Stock ( 7,205,393 ) — Tailwind Sponsor Series A Preferred Stock — 650,000 Tailwind public shares issuance of Series A Preferred Stock — 316,188 Legacy Nuburu shares 31,323,904 1,377,265 Lincoln Park Commitment Shares 200,000 — Anzu Warrant Shares — 500,000 Total shares of Nuburu Common Stock outstanding immediately after the Business Combination (1)(2) ​ 32,990,092 ​ 2,843,453 (1) Excludes 3,675,976 shares of Common Stock as of the Closing of the Business Combination to be reserved for potential future issuance upon the exercise of Nuburu options or settlement of Nuburu RSUs. (2) Excludes 16,710,785 Public Warrants issued and outstanding as of the Closing of the Business Combination. The Business Combination is accounted for as a reverse recapitalization in accordance with GAAP because Legacy Nuburu has been determined to be the accounting acquirer. Under this method of accounting, Tailwind, which is the legal acquirer, is treated as the accounting acquiree for financial reporting purposes and Legacy Nuburu, which is the legal acquiree, is treated as the accounting acquirer. Accordingly, the consolidated assets, liabilities and results of operations of Legacy Nuburu have become the historical financial statements of Nuburu, and Tailwind’s assets, liabilities and results of operations have been consolidated with Legacy Nuburu’s beginning on the acquisition date. For accounting purposes, the financial statements of Nuburu represent a continuation of the financial statements of Legacy Nuburu with the Business Combination being treated as the equivalent of Legacy Nuburu issuing stock for the net assets of Tailwind, accompanied by a recapitalization. The net assets of Tailwind are stated at historical costs and no goodwill or other intangible assets have been recorded. Operations prior to the Business Combination will be presented as those of Legacy Nuburu in future reports of Nuburu. Legacy Nuburu was determined to be the accounting acquirer based on evaluation of the following facts and circumstances: • Legacy Nuburu stockholders comprise a majority of the voting power of Nuburu; • The Nuburu board of directors consists only of members of the Legacy Nuburu board of directors or nominees selected by Legacy Nuburu; • Legacy Nuburu’s operations prior to the acquisition comprise the only ongoing operations of Nuburu; • Legacy Nuburu’s senior management comprises the senior management of Nuburu; • Nuburu has assumed the Legacy Nuburu name; and • Legacy Nuburu’s headquarters have become Nuburu’s headquarters. All periods prior to the Business Combination have been retrospectively adjusted using the Exchange Ratios for the equivalent number of shares outstanding immediately after the Closing to effect the reverse recapitalization. In connection with the Closing of the Business Combination, the Company received net proceeds from the Business Combination totaling $ 3.2 million, prior to deducting transaction and issuance costs. Legacy Nuburu’s total transaction expenses were approximately $ 3.2 million and Tailwind’s total transaction expenses were approximately $ 2.5 million after taking into account waivers of costs incurred by Legacy Nuburu and Tailwind.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	NOTE 5. FAIR VALUE MEASUREMENTS Assets and liabilities recorded at fair value on a recurring basis in the balance sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair values. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, as follows: Level 1: Valuations based on quoted prices for identical assets and liabilities in active markets. Level 2: Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3: Valuations based on unobservable inputs reflecting our own assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment. The assets’ or liabilities’ fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The Company’s financial instruments that are carried at fair value consists of Level 1 assets and liabilities. Level 1 assets include highly liquid bank deposits and money market funds, which were not material as of June 30, 2023 and December 31, 2022. Level 1 liabilities include the Public Warrants and are classified as Level 1 due to the use of an observable market quote in an active market. The Company measured the fair value of the Public Warrants on the date of the Closing of the Business Combination based on the close price of the Public Warrant price. During the three and six months ended June 30, 2023, no warrants were exercised. The gains and losses from re-measurement of Level 1 financial liabilities are recorded as part of other (expense) income, net in the condensed consolidated statements of operations and comprehensive loss. During the three and six months ended June 30, 2023, the Company recorded a gain of $ 334,215 and $ 835,539 , respectively, related to the change in fair value of the Public Warrants from the Closing to the end of the period. There were no transfers between Level 1, Level 2 and Level 3 in any periods presented. The following table sets forth the fair value of the Company’s financial liabilities by level within the fair value hierarchy: ​ At June 30, 2023 ​ Level 1 Level 2 Level 3 Total Public Warrants $ 501,324 $ — ​ $ — ​ $ 501,324 The following table sets forth a summary of the changes in fair value of the Company’s Level 1 financial liabilities : ​ ​ Three months ended June 30, ​ Six months ended June 30, 2023 2023 Fair value, beginning of period ​ $ 835,539 ​ $ — Recognition of Public Warrants upon the reverse recapitalization — 1,336,863 Change in fair value ​ ( 334,215 ) ​ ( 835,539 ) Fair value as of June 30, 2023 ​ $ 501,324 ​ $ 501,324

The Company will accrue a liability for legal proceedings when it is probable that a liability has been incurred and the amount can be reasonably estimated. Significant judgment is required to determine both probability and the estimated amount. When only a range of possible loss can be established, the most probable amount in the range is accrued. If no amount within this range is a better estimate than any other amount within the range, the minimum amount in the range is accrued. At June 30, 2023 and December 31, 2022, the Company was not involved in any material legal proceedings. Purchase Commitments On June 30, 2023, the Company had $ 303,182 in outstanding firm purchase commitments to acquire inventory and research and development parts from suppliers for the Company's ongoing operations.

Revenue from Contract with Customer [Abstract]
REVENUES	NOTE 7. REVENUES The Company’s primary business activity involves sales and installation services of high-powered lasers. The Company has sales to customers throughout the U.S., Europe, and Asia. All sales are settled in U.S. dollars. The following table presents revenue disaggregated by geography: ​ ​ Three Months Ended ​ Six Months Ended ​ 2023 2022 2023 2022 United States ​ $ 997,066 ​ $ 35,000 ​ $ 1,237,066 $ 125,000 Asia 55,000 ​ — 170,500 — Europe ​ 1,996 ​ 12,375 ​ 116,485 12,375 Total ​ $ 1,054,062 ​ $ 47,375 ​ $ 1,524,051 $ 137,375 At contract inception, the Company assesses the goods or services promised within each contract and determines the performance obligations and assesses whether each promised good or service is distinct. The Company then recognizes revenue for the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. Determining the method and amount of revenue to recognize requires the Company to make judgments and estimates which include determining whether the performance obligation is satisfied over time or at a point in time, the selection of method to measure progress towards completion, and determining if the contract includes any variable consideration or material right elements. The Company’s primary performance obligations include product sales and installation services. Revenue for product sales is recognized when the customer obtains control of the product, which occurs at a point in time, and may be upon shipment or upon delivery based on the contractual shipping terms of a contract. Revenue for installation services is recognized over time, as the service is rendered. For this performance obligation, the Company has a right to consideration from customers that corresponds directly with the value to the customers of the Company's performance completed to date, and as such, the Company recognizes revenue in the amount to which it has a right to invoice the customer. Typically, invoices are issued upon shipment or completion of services, which varies based on the product and service duration. The Company allocates the transaction price based on the estimated relative standalone selling prices of the promised products or services underlying each performance obligation. The Company determines standalone selling prices based on the price at which the performance obligation is sold separately. If the standalone selling price is not observable through past transactions; the Company estimates the standalone selling price taking into account available information such as market conditions and internally approved standard pricing related to the performance obligations. Special consideration is given to change orders. A change order will be treated as a separate contract if the additional goods or services are distinct. The payment terms and conditions in customer contracts vary. However, the Company typically does not have contracts with customers in which payment terms are greater than 90 days. As such, the Company does not assess whether a significant financing component exists if the period between when it performs its obligations under the contract and when the customer pays, is one year or less. Contract liabilities consist of customer deposits that are applied to invoices as the performance obligation is performed. Accounts receivable and contract liabilities as of June 30, 2023 and December 31, 2022, were as follows: ​ Accounts Receivable ​ Contract Liabilities December 31, 2022 ​ $ 327,200 ​ $ 178,750 June 30, 2023 ​ 646,935 ​ 180,075 During the three months ended June 30, 2023 and 2022, the Company did no t recognize any revenue that was included in the contract liabilities balance at the beginning of the reporting period. During the six months ended June 30, 2023 and 2022, the Company recognized $ 5,000 and nil of revenue that was included in the contract liabilities balance at the beginning of the reporting period, respectively. The Company recognizes freight and shipping costs associated with outbound freight after control over a product has transferred to a customer, as a fulfillment cost and includes those costs in materials within cost of revenues. Revenue received from shipping and handling fees is reflected in net revenues. The Company's standard terms and conditions which are applicable to the Company's contracts covering the sale of its products include warranty provisions that provide assurance to its customers that the products will comply with agreed upon specifications, which is standard in the industry. The product warranty is accounted for in accordance with the guidelines under ASC 460 10, Guarantees. Therefore, losses from warranty obligations are accrued when the amount of loss can be reasonably estimated, and the information is available before the financial statements are issued or are available to be issued. The Company has determined that the nature, amount, timing, and uncertainty of revenue and cash flow are most significantly affected by their customer concentration, changes in technology, and adverse changes in the economy that may have an adverse impact on the ability of customers to contract with and pay the Company. Revenues from contracts with customers are disaggregated as follows: ​ ​ Three Months Ended ​ Six Months Ended ​ 2023 2022 2023 2022 Revenues recognized at a point in time ​ $ 1,049,062 ​ $ 47,375 ​ $ 1,519,051 ​ $ 137,375 Revenues recognized over time ​ 5,000 ​ — ​ 5,000 ​ — Total ​ $ 1,054,062 ​ $ 47,375 ​ $ 1,524,051 ​ $ 137,375

CONVERTIBLE PREFERRED STOCK	NOTE 9. CONVERTIBLE PREFERRED STOCK Legacy Nuburu Preferred Stock Financing In multiple closings in December 2021 and January 2022, Legacy Nuburu sold an aggregate of 1,166,372 shares of Legacy Nuburu Series C Preferred Stock, at a purchase price of $ 5.00 per share, for an aggregate purchase price of approximately $ 5.8 million. Series A Preferred Stock Ranking The Company’s Preferred Stock ranks senior to the Company’s Common Stock with respect to rights on the distribution of assets on any voluntary or involuntary liquidation, dissolution or winding up of the affairs of the Company. Dividends Holders of the Company’s Preferred Stock participate, on an as-converted basis (without regard to any conversion limitations) in all dividends paid to the holders of the Company’s Common Stock. Conversion Rights The Preferred Stock is convertible at any time into Common Stock at a conversion rate equal to $ 10.00 (subject to equitable adjustment in the event of a stock split, stock consolidation, subdivision or certain other events of a similar nature that increase or decrease the number of shares of Preferred Stock outstanding (the “Original Issuance Price”)) divided by the lesser of (i) $ 11.50 and (ii) the greater of (x) 115 % of the lowest volume-weighted average price per share of the Company’s Common Stock as displayed under the heading Bloomberg VWAP (the “VWAP”) for any consecutive ninety-trading day period prior to the calculation of such VWAP and (y) $ 5.00 , in each case subject to adjustment as set forth in the Certificate of Designations (the “Conversion Price”). Any conversion will be settled only in shares of Common Stock; provided, that, upon any conversion that would result in the holders beneficially owning greater than 9.99 % of the Company’s voting stock outstanding as of the conversion date or any individual holder beneficially owning Common Stock in excess of the maximum number of shares of Common Stock that could be issued to the holder without triggering a change of control under the applicable stock exchange listing rules, the excess, if any, of the conversion consideration otherwise payable upon such conversion shall be paid in cash, based on an amount per share of Common Stock equal to the last reported price per share of the Common Stock on the trading day immediately preceding the conversion date. Mandatory Conversion If the VWAP is greater than 200 % of the Conversion Price for any 20 trading days in a 30-day trading day period, the Company may elect to convert all, but not less than all, of the Preferred Stock then outstanding into the Company’s Common Stock at a conversion rate with respect to each share of Preferred Stock equal to the Original Issuance Price as of the date of such conversion divided by the then applicable Conversion Price. Voting Rights The holders of Preferred Stock are not entitled to vote at or receive notice of any meeting of stockholders, except the holders of Preferred Stock are entitled to certain consent rights on matters related to (i) the creation or authorization of the creation of any equity or debt securities of the Company that rank senior or equal to certain rights of the Preferred Stock and (ii) the authorization of any adverse change to the powers, preferences, or special rights of the Preferred Stock set forth in the Company’s Certificate of Incorporation or Bylaws, and shall have voting rights as required by law. Redemption On the second anniversary of the Closing Date, or January 31, 2025 (the “Test Date”), the Company is obligated to redeem the maximum portion of the Preferred Stock permitted by law in cash at an amount equal to the Original Issuance Price as of such date if the Conversion Price exceeds the VWAP. If, on the Test Date, the Conversion Price is equal to or less than the VWAP, the Company must convert all shares of Preferred Stock then outstanding into shares of the Company’s Common Stock at the then applicable Conversion Price. Notwithstanding the foregoing, the Company shall not be required to redeem any shares of Preferred Stock to the extent the Company does not have legally available funds to effect such redemption. The mandatory redemption and conversion provisions described herein are further subject to certain limitations detailed in the Certificate of Designations. Series A Preferred Stock Issuances The Company is authorized to issue 50,000,000 shares of preferred stock with a par value of $ 0.0001 per share with such designation, rights and preferences as may be determined from time to time by the Company’s board of directors. As of June 30, 2023 and December 31, 2022, there were 3,038,905 and 23,237,703 shares of preferred stock issued or outstanding, respectively. Upon the Closing of the Business Combination, all 23,237,703 shares of issued and outstanding convertible preferred stock were cancelled and converted into 23,237,703 shares of Legacy Nuburu common stock based upon the conversion rate as calculated pursuant to Legacy Nuburu's Certificate of Incorporation, multiplied by the Exchange Ratios at the Effective Time. Additionally, upon the Closing of the Business Combination, the cancellation and conversion of all Legacy Nuburu Company Notes into shares of Legacy Nuburu common stock in accordance with its terms as of immediately prior to the Effective Time resulted in the issuance of 2,642,239 shares which were then outstanding as Legacy Nuburu common stock as of immediately prior to the Effective Time and subsequently converted into 1,361,787 shares of Nuburu Common Stock and 1,361,787 shares of Nuburu Series A preferred stock at the Effective Time. As of the Closing, each Legacy Nuburu stockholder waived its right to participate in the Preferred Stock Issuance (for clarity, excluding any shares received as a result of the conversion of any Legacy Company Notes prior to the Closing, which were entitled to participate in the Preferred Stock Issuance). Legacy Nuburu stockholders were entitled to receive approximately 99 % of the Common Stock issued as merger consideration pursuant to the Business Combination Agreement agreed to waive such right by entering into the Stockholder Support Agreement (for clarity, excluding any shares received as a result of the conversion of any Legacy Company Notes). Those Legacy Nuburu stockholders who did not waive their right to participate resulted in the issuance of 15,478 shares of Nuburu Series A preferred stock at the Effective Time. Each Tailwind stockholder who did not redeem their shares received a share of Nuburu Series A preferred stock. This resulted in the issuance of 316,188 shares of Nuburu Series A preferred stock to those non-redeeming stockholders. Tailwind and the Tailwind Sponsor entered into the Sponsor Support and Forfeiture Agreement. In connection with the Business Combination, the 8,355,393 Founder Shares were forfeited other than 1,150,000 shares of Common Stock (of which, 150,000 shares were transferred to Nautilus Maser Fund, L.P. and 50,000 shares were transferred to Cohen & Company Capital Markets at Closing) and 650,000 shares of Series A preferred stock. Wilson Sonsini Goodrich & Rosati, Professional Corporation (“WSGR”) was engaged by Legacy Nuburu to act as its counsel for the Business Combination. As partial compensation for the services provided by WSGR to Legacy Nuburu in connection with the Business Combination, the Company agreed to issue to WSGR 195,452 shares of Common Stock and 195,452 shares of Preferred Stock pursuant to the terms of the Stock Purchase Agreement entered into by and between the Company and WSGR on March 10, 2023. The foregoing issuance was made in a transaction not involving a public offering pursuant to an exemption from the registration requirements of the Securities Act in reliance upon Section 4(a)(2) of the Securities Act or Regulation D promulgated under the Securities Act. Legacy Nuburu entered into an engagement letter with Anzu Partners on August 30, 2022 pursuant to which Legacy Nuburu, in recognition of past Services, (i) agreed to pay $ 500,000 to Anzu Partners upon the closing of the Business Combination and (ii) issued a warrant with a strike price of $ 0.01 per share to Anzu Partners for 500,000 shares of Preferred Stock (the “Anzu Partners Warrant”). This warrant was exercised by Anzu Partners in connection with the Closing and the $ 500,000 payment was made during the three months ended June 30, 2023.

Warrant Liability [Abstract]
WARRANTS	NOTE 10. WARRANTS Equity Classified Common Stock Warrants In connection with the Private Placement discussed in Note 8 - Convertible Notes Payable , the Company issued Warrants to purchase up to 11,518,895 shares of the Company's Common Stock pursuant to the June 12, 2023 Purchase Agreement and 1,889,535 shares of Common Stock pursuant to the June 16, 2023 Purchase Agreement. The Warrants have an exercise price equal to $ 1.03 and expire on June 23, 2028 . As the Warrants were part of a bundled transaction, the gross proceeds from the Private Placement of $ 9,225,000 were allocated to Convertible Notes Payable and Warrants based on their respective relative fair value upon issuance. The aggregate fair value of the Warrants of $ 3,401,366 was estimated using the Black-Scholes option-pricing model with the following assumptions: ​ Upon Issuance Common Stock Warrants: ​ Expected term (in years) 5.0 Expected volatility 47.9 % Risk-free interest rate 4.0 % Expected dividend yield 0.0 % The allocated proceeds from the Warrants of $ 2,511,759 were recorded in additional paid-in capital. Liability Classified Public Warrants In connection with the closing of the Business Combination, Nuburu assumed the 16,710,785 Public Warrants outstanding on the date of Closing. As of June 30, 2023, all 16,710,785 Public Warrants remain outstanding. Each whole warrant entitles the registered holder to purchase one share of Common Stock at a price of $ 11.50 per share, subject to adjustment as discussed below, at any time commencing 30 days after the completion of the Business Combination. Pursuant to the Warrant Agreement, a warrant holder may exercise its warrants only for a whole number of shares of Common Stock. The warrants will expire five years after the completion of the Business Combination, at 5:00 p.m., New York City time, or earlier upon redemption or liquidation. Redemptions of warrants when the price of Common Stock equals or exceeds $ 18.00 — Once the Public Warrants become exercisable, the Company may redeem the Public Warrants: • in whole and not in part; • at a price of $ 0.01 per warrant; • upon not less than 30 days’ prior written notice of redemption to each warrant holder; and • if, and only if, the closing price of the Common Stock equals or exceeds $ 18.00 per share for any 20 trading days within a 30 -trading day period ending three trading days before the Company sends the notice of redemption to the warrant holders. If and when the Public Warrants become redeemable by the Company, it may exercise its redemption right even if the Company is unable to register or qualify the underlying securities for sale under all applicable state securities laws. Redemption of warrants when the price per share of Common Stock equals or exceeds $ 10.00 — Once the Public Warrants become exercisable, the Company may redeem the Public Warrants: • in whole and not in part; • at $ 0.10 per warrant upon a minimum of 30 days’ prior written notice of redemption provided that holders will be able to exercise their warrants on a cashless basis prior to redemption and receive that number of shares based on the redemption date and the fair market value of the Common Stock; • if, and only if, the last reported sale price of the Common Stock equals or exceeds $ 10.00 per share (as adjusted per stock splits, stock dividends, reorganizations, reclassifications, recapitalizations and the like) for any 20 trading days within the 30 -trading day period ending three trading days before the Company sends the notice of redemption to the warrant holders; and • if the closing price of the Common Stock for any 20 trading days within a 30 -trading day period ending on the third trading day prior to the date on which the Company sends the notice of redemption to the warrant holders is less than $ 18.00 per share, the Private Placement Warrants must also be concurrently called for redemption on the same terms as the outstanding Public Warrants, as described above.

Share-Based Payment Arrangement [Abstract]
STOCK-BASED COMPENSATION	NOTE 11. STOCK-BASED COMPENSATION As of June 30, 2022, the Company had an active stock-based incentive compensation plan and an employee stock purchase plan: the 2022 Equity Incentive Plan (the “2022 Plan”) and the 2022 Employee Stock Purchase Plan (the “ESPP”). All new equity compensation grants are issued under these two plans; however, outstanding awards previously issued under inactive plans will continue to vest and remain exercisable in accordance with the terms of the respective plans. The 2022 Plan provides for the grant of stock and stock-based awards including stock options, restricted stock, restricted stock units, performance awards, and stock appreciation rights. As of June 30, 2022, there were 7.1 million shares available for grant under the 2022 Plan and 0.4 million shares available for grant under the ESPP. Stock-Based Compensation Expense Total stock-based compensation expense recognized in the Company’s condensed consolidated statements of operations and comprehensive loss is classified as follows: ​ ​ Three Months Ended ​ Six Months Ended ​ 2023 2022 2023 2022 Cost of revenues ​ $ 225,985 ​ $ 366,608 ​ $ 354,728 $ 396,898 Research and development 197,518 ​ 47,603 334,283 47,351 Selling and marketing 87,825 13,091 99,512 45,030 General and administrative ​ 285,454 ​ 769,931 ​ 472,238 777,409 Total stock-based compensation expense ​ $ 796,782 ​ $ 1,197,233 ​ $ 1,260,761 $ 1,266,688 The Company’s stock-based compensation expense is based on the value of the portion of stock-based payment awards that are ultimately expected to vest. During the three months ended June 30, 2023 and 2022, stock-based compensation relating to stock-based awards granted to consultants was $ 145,079 and $ 700,506 , respectively. During the six months ended June 30, 2023 and 2022, stock-based compensation relating to stock-based awards granted to consultants was $ 262,168 and $ 721,523 , respectively. Restricted Stock Units The Company grants Restricted Stock Units, or RSUs, to its employees for their services with a liquidity event requirement. The RSUs granted to employees vest over a period of time from the grant date and are subject to the participants continuing service to the Company over the period. ​ ​ RSUs ​ Number of Shares Weighted Average Grant Date Fair Value Unvested at December 31, 2022 ​ 542,706 ​ $ 6.11 RSUs granted 709,636 $ 2.23 RSUs vested ( 292,757 ) $ 4.27 RSUs forfeited ( 21,875 ) $ 2.14 Unvested at June 30, 2023 937,710 $ 1.53 Vested and unreleased 277,132 Outstanding at June 30, 2023 1,214,842 ​ The total grant date fair value of RSUs awarded was $ 1,583,995 and $ 3,316,950 for the six months ended June 30, 2023 and 2022, respectively. The total grant date fair value of RSUs vested was $ 1,250,715 and nil during the six months ended June 30, 2023 and 2022, respectively. As of June 30, 2023, total unrecognized stock-based compensation costs related to RSUs were $ 3,309,212 , which are expected to be recognized over a remaining weighted average period of 2.3 years. As of June 30, 2023, all of the RSUs are expected to vest. Stock Options The Company's outstanding stock options generally expire 10 years from the date of grant and are exercisable when the options vest, generally over four years , the majority of which vest at a rate of 25 % on the first anniversary of the grant date, with the remainder vesting ratably each month over the next three years . A summary of stock option activity is as follows: ​ Number of Stock Options Outstanding Weighted-Average Exercise Price Weighted-Average Remaining Contractual Life (Years) Aggregate Intrinsic Value Options outstanding at December 31, 2022 ​ 3,133,270 ​ $ 4.35 ​ 7.9 ​ $ 5,484,316 Options granted 115,000 $ 3.49 Options exercised ( 5,153 ) $ 1.36 Options cancelled or forfeited ( 36,072 ) $ 5.98 Options outstanding at June 30, 2023 3,207,045 $ 4.31 7.5 $ 241,144 Options exercisable at June 30, 2023 2,006,246 $ 3.77 6.9 $ 217,877 Options vested and expected to vest at June 30, 2023 3,207,045 ​ $ 4.31 7.5 ​ $ 241,144 The weighted-average grant date fair value of options granted to employees and consultants was $ 2.15 and $ 1.44 per share for the six months ended June 30, 2023 and 2022, respectively. Aggregate intrinsic value represents the difference between the estimated fair value of the underlying Common Stock and the exercise price of outstanding, in-the-money options. The aggregate intrinsic value of options exercised was $ 1,040 and $ 2,158,402 for the three months ended June 30, 2023 and 2022, respectively. As of June 30, 2023, total unrecognized stock-based compensation cost related to stock options was $ 2,322,457 , which is expected to be recognized over a weighted-average period of 2.0 years. Determining the appropriate fair value of stock based awards requires the input of subjective assumptions including the fair value of the Company’s Common Stock, the expected life of the option, and expected stock price volatility. The Company used the Black Scholes option pricing model to value its stock option awards. The Company estimates the fair value of the options utilizing the Black-Scholes option pricing model, which is dependent upon several variables, including expected option term, expected volatility of the Company’s share price over the expected term, expected risk-free interest rate over the expected option term, and expected dividend yield rate over the expected option term, and actual forfeiture rates. A summary of the assumptions Legacy Nuburu utilized for option grants during the six months ended June 30, 2022 are as follows: ​ ​ Six Months Ended June 30, ​ 2023 2022 Expected term (in years) ​ 5.0 ​ 5.0 Expected volatility 46.7 % 36.0 % Risk-free interest rate 3.4 % 2.2 % Expected dividend yield 0.0 % ​ 0.0 %

INCOME TAX

Income Tax Disclosure [Abstract]
INCOME TAX	NOTE 12. INCOME TAX Due to the current operating losses, the Company recorded zero income tax expense during the three and six months ended June 30, 2023 and 2022. During these periods, the Company’s activities were limited to U.S. federal and state tax jurisdictions, as it does not have any significant foreign operations. Due to the Company’s history of cumulative losses and after considering all the available objective evidence, management concluded that it is not more likely than not that all of the Company’s net deferred tax assets will be realized in the future. Accordingly, the Company’s deferred tax assets, which include net operating loss (“NOL”), carryforwards and tax credits related primarily to research and development, continue to be subject to a valuation allowance as of June 30, 2023. The Company expects to continue to maintain a full valuation allowance until there is sufficient evidence to support recoverability of its deferred tax assets. Utilization of the NOL carryforwards and credits may be subject to a substantial annual limitation due to the ownership change limitations provided by Section 382 and Section 383 of the Internal Revenue Code of 1986, as amended, and similar state provisions. Generally, in addition to certain entity reorganizations, the limitation applies when one or more "5-percent stockholders" increase their ownership, in the aggregate, by more than 50 percentage points over a 36-month time period testing period, or beginning the day after the most recent ownership change, if shorter.

NET LOSS PER SHARE	NOTE 13. NET LOSS PER SHARE Diluted earnings per share (“EPS”) includes the dilutive effect of Common Stock equivalents and is computed using the weighted-average number of Common Stock and Common Stock equivalents outstanding during the reporting period. Diluted EPS for the three and six months ended June 30, 2023 and 2022 excluded Common Stock equivalents because the effect of their inclusion would be anti-dilutive or would decrease the reported loss per share. The following table sets forth securities outstanding that could potentially dilute the calculation of diluted earnings per share: ​ ​ For the Six Months Ended June 30, ​ 2023 2022 Stock options outstanding ​ 3,207,045 ​ 3,153,890 Warrants to purchase Common Stock - liability classified 16,710,785 — Warrants to purchase Common Stock - equity classified 13,408,430 1,167,557 Unvested restricted stock units 937,710 542,706 If-converted Common Stock from Series A Preferred Stock (1) 6,077,810 — If-converted Common Stock from convertible notes 13,426,430 — If-converted common shares from Legacy Nuburu convertible notes — 23,331 Total 53,768,210 ​ 4,887,484 (1) Assumes that all shares of Series A Preferred Stock are converted into Common Stock at a conversion rate equal to $ 10.00 divided by $ 5.00 , representing the maximum number of shares issuable to holders of Series A Preferred Stock.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	6 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S.GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 8 of Regulation S-X of the SEC. Certain information or footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial reporting. Accordingly, they do not include all the information and footnotes necessary for a complete presentation of financial position, results of operations, or cash flows. In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all adjustments, consisting of a normal recurring nature, which are necessary for a fair presentation of the financial position, operating results and cash flows for the periods presented. The results of operations for the three and six months ended June 30, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023 or any future period. These unaudited condensed consolidated financial statements and their notes should be read in conjunction with the Company’s Annual Report on Form 10-K as filed with the SEC on March 31, 2023 and the audited financial statements of Legacy Nuburu for the years ended December 31, 2022 and 2021 included in the Amendment No. 1 to the Form 8-K filed with the SEC on March 31, 2023.
Principles of Consolidation	Principles of Consolidation The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary. All significant intercompany balances and transactions have been eliminated in consolidation.
Emerging Growth Company	Emerging Growth Company The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. Significant Accounting Policies The significant accounting policies used in preparation of these condensed consolidated financial statements are disclosed in the notes to consolidated financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022 filed with the SEC on March 31, 2023 and the audited financial statements of Legacy Nuburu for the years ended December 31, 2022 and 2021 included in the Amendment No. 1 to the Form 8-K filed with the SEC on March 31, 2023. The significant accounting policies have not changed significantly since those filings.
