Equity Award Plans

In January 2025, the Company’s board of directors approved, and the Company adopted the 2025 Incentive Award Plan (the “2025 Incentive Plan”), replacing the historical 2011 Amended Stock Plan. The 2025 Incentive Plan became effective on January 13, 2025. The 2025 Incentive Plan provides for the grant of stock options (both incentive stock options and

non-qualified

stock options), stock appreciation rights, restricted stock, RSUs and other stock or cash based awards to employees and consultants of the Company and its subsidiaries and members of the board of directors of the Company.

Under the 2025 Incentive Plan, stock options, including incentive stock options (“ISOs”), may be granted to employees at exercise prices not lower than the fair value of the stock as of the date of grant. For ISOs granted to a person whom, at the time of the grant, owns stock representing more than 10% of the total combined voting power of all classes of our stock, the per share exercise price must be no less than 110% of the fair value on the date of the grant as determined by the Board.

The Company recognizes compensation expense for service-based options on a straight-line basis over the requisite service period of all employees or

non-employees,

which is the award’s vesting term, generally over four years. The Company accounts for forfeitures when they occur.

Under the 2025 Incentive Plan, RSUs are unfunded, unsecured rights to receive, on the applicable settlement date, shares of common stock or an amount in cash, or a combination thereof, as determined by the Administrator, subject to vesting conditions, which may include continued employment or service, or the achievement of performance criteria established by the Administrator.

As of March 31, 2025, no equity awards have been granted under the 2025 Incentive Plan and 25,397,242 shares of common stock were reserved for issuance under the plan.

Following the effectiveness of the 2025 Incentive Plan, the Company ceased making grants under the 2011 Equity Incentive Plan (the “2011Amended Plan”) and all remaining unissued shares were retired. However, the 2011 Amended Plan continues to govern the terms and conditions of the outstanding awards granted under it. Shares of common stock subject to the awards granted under the 2011 Plan that cease to be subject to such awards by forfeiture or otherwise after the termination of the 2011 Amended Plan will be retired and no longer be available for issuance.

Under the 2011 Amended Plan, we issued RSUs, which vested upon the satisfaction of both the service-based condition and a liquidity event condition. The liquidity event condition for the RSUs was satisfied upon the occurrence of a qualifying event, defined specifically in the equity documents, and generally refer to the earlier of a specified period of time subsequent to an initial public offering or an acquisition, in all cases prior to the expiration date of the award (see Note 3). Additionally, for all terminated RSU grants, all RSUs which have satisfied a portion or all of the service-based condition of the termination date remain with the stockholder and do not return to the pool of shares available for issuance until the earlier of the satisfaction of the liquidity event (at which time those RSUs vest) or the expiration date of the award. The RSUs expired as defined by the individual RSU grant, generally the earlier of (i) the first anniversary or second anniversary of terminated service, for 2023 and prior grants, respectively, for any reason and (ii) expire date defined as the fifth anniversary of the date of grant. The fair value of RSUs was determined based on the estimated fair value of shares of common stock at the date of grant, as determined by the Board of Directors.

Stock Options

A summary of stock option activity under the 2011 Amended Plan is as follows:


	Number of Options			Weighted average exercise price		Weighted average remaining contractual life (in years)		Aggregate intrinsic value (in thousands)
Outstanding as of December 31, 2024		28,360,635		$	1.27		9.2	$	22,741
Forfeited		(318,400	)		1.18

Outstanding as of March 31, 2025		28,042,235		$	1.27		8.9		30,225

Vested and expected to vest as of March 31, 2025		28,042,235		$	1.27		8.9		30,225

Exercisable as of March 31, 2025		8,472,388		$	1.87		8.1		10,342

As of March 31, 2025, there was approximately $19.0 million of total unrecognized compensation cost related to unvested stock options, which is expected to be recognized over a weighted average period of 2.3 years.

The Company uses the Black-Scholes option-pricing model to determine the grant-date fair value of stock options. The determination of the fair value of stock options on the grant date is affected by the estimated underlying common stock price, as well as assumptions regarding a number of complex and subjective variables. These variables include expected stock price volatility over the term of the awards, actual and projected employee stock option exercise behaviors, risk-free interest rates, and expected dividends. There were no stock options granted during the three months ended March 31, 2025.

RSUs

A summary of the Company’s RSU activity issued under the 2011 Amended Plan is as follows:


	RSUs Awarded			Weighted average grant date fair value
Nonvested as of December 31, 2024		3,630,447		$	1.53
Vested		(2,464,171	)		1.76
Forfeited		(15,552	)		0.73

Nonvested as of March 31, 2025		1,150,724		$	1.04

Immediately prior to the consummation of the Merger, the RSUs had both a service-based condition and a liquidity event condition. The liquidity event condition was only satisfied on the consummation of a liquidity event, such as an IPO, which was not determinable or probable as of December 31, 2024. Effective with the consummation of the Merger, we recognized $3.9 million in stock-based compensation expense associated with the vesting of the outstanding RSUs (see Note 3).

As of March 31, 2025, the 2,464,171 common stock shares that are subject to the release of the vested RSU have not been issued holders but have been included in the weighted average shares outstanding calculation for purposes of earning per share (see Note 17).

As of March 31, 2025, there was approximately $1.0 million of total unrecognized compensation cost related to unvested RSUs, which is expected to be recognized over a weighted average period of 0.8 years.

Employee Stock Purchase Plans

In January 2025, the Company’s board of directors adopted the 2025 Employee Stock Purchase Plan (the “2025 ESPP”) that became effective upon the date of the

de-SPAC

in order to enable eligible employees to purchase shares of common stock with accumulated payroll deductions. The 2025 ESPP is intended to qualify under Section 423 of the Internal Revenue Code, as amended. Under the 2025 ESPP, eligible employees are offered the option to purchase share of common stock at a discount over a series of offering periods. Each offering period may consist of one or more purchase periods. The purchase price for shares of common stock purchased under the 2025 ESPP will be 85% of the lesser of the fair market value of shares of common stock on (i) the first trading day of the applicable offering period or (ii) the last trading day of each purchase period in the applicable offering period.

As of March 31, 2025, 3,047,669 shares of common stock were reserved for issuance pursuant to the 2025 ESPP. As of March 31, 2025, no offers have been made to purchase shares of the Company’s common stock.

Total liabilities, measured at fair value	$	—	$	—	$	163,340	$	163,340

Level 1 instruments consisted of U.S. Government treasury securities, U.S. Government money market funds, and mutual funds because they were valued using quoted prices in active markets and can be redeemed on any business days with an intermediary.

Level 3 instruments consisted of earnout share liabilities. The Company has elected to apply the fair value option to measure all historical convertible notes and warrant liabilities (see Notes 8 and 9) and current earnout shares due to the nature of their embedded features.

Changes in the fair value measurement of Level 3 liabilities related to unrealized gains (losses) resulting from remeasurement of our outstanding historical convertible notes and warrant liabilities (see Notes 8 and 9) and current earnout shares. The respective changes for remeasurement are reflected in the change in fair value of convertible notes, change in fair value of warrant liabilities and change in fair value of the earnout liabilities in the condensed consolidated statements of operations.

The changes in the fair values of the Level 3 liabilities were as follows:


(Amounts in thousands)	Pay-to-Play Convertible Notes			2023 Convertible Notes			Warrant liabilities			Earnout share liabilities			Total
Balance as of December 31, 2024	$	15,942		$	132,687		$	14,711		$	—		$	163,340

Balance as of March 31, 2024	$	14,549		$	33,398	$	8,154	$	—	$	56,101

The Company’s convertible notes and related warrants outstanding as of December 31, 2024 were classified within level 3 of the fair value hierarchy because there was no active market for the liabilities or similar instruments.

There were no transfers between Level 1, Level 2, or Level 3 of the fair value hierarchy during the three months ended March 31, 2025 or 2024.

Upon the consummation of the Merger, all then outstanding convertible notes and warrant liabilities were converted into shares of common stock (see Note 3).

D-2

Shadow preferred stock warrants, the warrants issued with the P2P Notes and the 2023 Convertible Notes, and the

pre-funded

common stock warrants (see Notes 7 and 8). The Company has elected to apply the fair value option to measure all convertible notes due to the nature of their embedded features.

Changes in the fair value measurement of Level 3 liabilities related to unrealized gains (losses) resulting from remeasurement of the Company’s outstanding convertible notes and warrant liabilities (see Notes 7 and 8) are reflected in the change in fair value of convertible notes and change in fair value of warrant liabilities in the consolidated statements of operations.

The change in the fair value of the Level 3 liabilities during the years ended December 31, 2024 and 2023 was as follows (in thousands):

Balance at December 31, 2024	$	15,942	$	132,687	$	14,711	$	163,340

The Company’s convertible notes and related warrants were classified within level 3 of the fair value hierarchy because there was no active market for the liabilities or similar instruments.

There were no transfers between Level 1, Level 2, or Level 3 of the fair value hierarchy during the years ended December 31, 2024 and 2023. Certain existing investors invested in P2P Notes during the year ended December 31, 2023, and accordingly, their common stock warrants were converted into Series D Shadow preferred stock warrants and reclassified as warrant liabilities (see Notes 7, 8 and 13).

Effective with the Merger on January 13, 2025, all outstanding convertible notes and outstanding warrant liabilities were converted (see Note 1).

Note 9. Warrants

Legacy Blaize Warrant Liabilities

In connection with the Company’s various historical debt and equity financing arrangements, the Company issued convertible preferred stock warrants to purchase shares of its various series of convertible preferred stock.

The convertible preferred stock warrants were classified as liabilities, with changes in fair value recorded through earnings, as the underlying convertible preferred shares can be redeemed by the holders of these shares upon the occurrence of certain events that are outside of our control. As of December 31, 2024, the Company had outstanding warrant liabilities of $14.7 million.

Immediately prior to the consummation of the Merger, each issued and outstanding convertible preferred stock warrant to purchase Legacy Blaize convertible preferred stock converted into a warrant to purchase shares of common stock (see Note 3), with each warrant subject to the same terms and conditions as were applicable to the original warrant and having an exercise price and number of shares of common stock purchasable based on the Exchange Ratio and other terms contained in the Merger Agreement (the “Private Warrants Conversion”).

After the Private Warrants Conversion, the Private Warrants are indexed to the shares of Company’s common stock, and therefore were reclassified from debt classified instruments to equity classified instruments.

Publicly and Privately Traded Warrants

Upon the consummation of the Merger, BurTech’s 28,750,000 public warrants and 898,250 private warrants outstanding immediately prior to the Merger became warrants of Blaize.

Each warrant entitles the holder to purchase one share of common stock at a price of $11.50 per share, subject to adjustments as described herein. The warrants expire at 5:00 p.m., New York City time on the warrant expiration date, which is five years after the completion of the Merger, or earlier upon redemption or liquidation.

The Company may redeem the outstanding 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 given after the warrants become exercisable (the

“30-day

redemption period”) to each warrant holder;

•

if, and only if, the reported last sale price of the common stock equals or exceeds $18.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within a

30-trading

day period commencing once the warrants become exercisable and ending three business days before the Company sends the notice of redemption to the warrant holders; and

•

If and only if, there is a current registration statement in effect with respect to the shares of common stock underlying such warrants.

If the Company calls the warrants for redemption, as described above, management will have the option to require all holders that wish to exercise warrants to do so on a “cashless basis.” In such event, each holder would pay the exercise price by surrendering the warrants for that number of shares of common stock equal to the quotient obtained by dividing (x) the product of the number of shares of common stock underlying the warrants, multiplied by the difference between the exercise price of the warrants and the “fair market value”, as described below, by (y) the fair market value. The “fair market value” shall mean the average reported last sale price of the shares of common stock for the five trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of warrants.

The Private Warrants, as well as any warrants underlying additional units we issue to BurTech, officers, directors, initial stockholders or their affiliates in payment of working capital loans made to the Company, will be identical to the warrants underlying the units offered in the initial public offering, except were will not be transferable, assignable or saleable until 30 days after the consummation of the Merger.

Common Stock Warrants

In February 2025, the Company issued 50,000 common stock warrants to advisors as compensation for services rendered. The warrants have a five-year term and a strike price of $11.50 per common stock share. The warrants were fair valued as of the date of issuance and recognized as an increase in additional

paid-in-capital.

The compensation expense recognized during the three months ended March 31, 2025 was approximately $12 thousand.

The assumptions used in the Black-Scholes option pricing model to fair value the common stock warrants were as follows:


	As of March 31, 2025
Risk-free rate		4.3	%
Expected life (in years)		5.0
Expected volatility		60.0	%
Dividend yield		—	%
Weighted average fair value of common stock	$	3.34

Note 8. Warrant Liabilities

P2P Warrants:

Certain investors who invested in the P2P Notes (see Notes 7 and 13) also received P2P Warrants for no additional consideration resulting in the allocation of proceeds between the P2P Notes and P2P Warrants (see Notes 7 and 13).

Under

the terms of the

2022

P NPA and related warrant agreements, the P

P Warrants will be exercisable, in whole or in part, during the term commencing on the date of issuance through the

three

-year anniversary of the date of issuance. The number of Warrants each Lender is entitled to is based on the timing of the Lender’s investment as well as the Lender’s amount of funding, wherein the “Conversion Shares” is defined as the type of equity shares to be issued in the future upon conversion of the P

P Notes. The total number of warrants ranges from

% to

% of the total Conversion Shares to be issued for Lenders who invest at or less then their pro rata portion and for Lenders who invest above their pro rata portion, the total number of warrant shares is an additional

% to

% of a calculated incremental number of shares over the designated pro rata portion.

During 2023, in connection with the additional issuance of P2P notes,

336,950 Series D Shadow Preferred Stock warrants were reinstated at a fair value of approximately $61,000 (see Note 7) and reclassified from equity to warrant liability.

Upon exercise, these P2P Warrants will enable the Lenders to purchase Conversion Shares at a price (“Conversion Price”) determined based on when P2P Warrants are exercised and shall no longer be exercisable and become null and void upon 10 days prior to the consummation of the Company’s sale of its Common Stock in a firm commitment underwritten public offering pursuant to a registration statement on Form

S-1

under the Securities Act of 1933 (an “IPO”), acquisition by a Special Purpose Acquisition Company (a “SPAC Transaction”) and a defined liquidity event. The P2P Warrants have a fixed total exercise price known at inception (based on the amount of consideration paid by each Lender) and upon exercise will be settled in a variable number of the Conversion Shares. The P2P Warrants are legally detachable and separately exercisable from the P2P Convertible Notes. The Company accounts for the P2P Warrants as liabilities measured at fair value with subsequent changes in fair value recognized in earnings (see Note 4).

Effective February 28, 2024 the Series D Shadow Preferred Stock warrants expired unexercised.

As provided by the terms of the P2P notes, the notes remained outstanding and were converted, at the option of the holders, to common stock upon the Closing Date (see Note 1).

2023 Convertible Note Warrants:

Investors in the 2023 Convertible Notes received warrants (“2023 Convertible Note Warrants”) exercisable upon the earliest to occur of a Next Equity Financing Conversion, Maturity Conversion, SPAC Conversion or Corporate Transaction, as defined, and expire, prior to the Amendment in April 2024 (see below), ten years from issuance (see Note 13). The 2023 Convertible Note Warrants were granted for no additional consideration resulting in the allocation of proceeds between the 2023 Convertible Note and 2023 Convertible Note Warrants (see Notes 7 and 13).

On April 22, 2024, as part of the Blaize, BurTech Merger Sub Inc., and Burkan amended the original Merger Agreement to make certain adjustments in connection with the Blaize Note Financing (see Note 7) and additional adjustments related to warrant financing including an increase in the base purchase price and changes to certain definitions and terms.

Under the terms of the

April 2024

amendment, the number of warrant shares issuable upon exercise is equal to the quotient obtained by dividing (i)

% or

(the higher percentage which applies only to investors who purchased a convertible note on or before July 3, 2023) of the original principal amount of the corresponding note by (ii) (y) with respect to a Next Equity Financing Conversion, Maturity Conversion, or a SPAC Conversion, the Exercise Price (as defined herein) or (z) with respect to a Corporate Transaction, a per share price equal to the value of the consideration payable to the holder of each share of common stock of the Company. The Exercise price is defined as follows:

•

With respect to a Next Equity Financing Conversion, the per share issue price by new money investors for the equity securities;

•

With respect to a Maturity Conversion, a per share price mutually agreed upon by the Company and the Requisite Noteholders;

•

With respect to a SPAC Conversion, $11.50 per share and

•

With respect to a Corporate Transaction, the Corporate Transaction Exercise Price, as defined

Additionally,

the expiration date of the warrants was changed from

years to

years from the original date of issuance.

The 2023 Convertible Note Warrants are legally detachable and separately exercisable from the 2023 Convertible Notes. The Company accounts for the 2023 Convertible Note Warrants as liabilities measured at fair value with subsequent changes in fair value recognized in earnings.

As provided by the terms of the 2023 Convertible Notes, the notes remained outstanding and were converted, at the option of the holders, to common stock upon the Closing Date (see Note 1).

Other Warrants:

In conjunction with the December 22, 2023 Merger Agreement, the Company entered into a

pre-funded

warrant agreement (the “Burkhan Pre-funded Warrant”) with one of the parties to the Merger. The Burkhan Pre-funded Warrant is only exercisable at the closing of the Merger and becomes null and void if the Merger Agreement is terminated. The Burkhan Pre-funded Warrant provides for the issuance of a sufficient number of Company common stock shares that would allow the warrant holder to acquire BurTech Class A common Stock upon the closing of the Merger. The maximum number of BurTech Class A Common Stock to be received under the Burkhan

Pre-funded

Warrant is

6,833,333

, wherein a portion of this total share amount is subject to reduction, depending on the Available Acquiror Cash, as defined in the Merger Agreement, at closing. Pursuant to the terms of the Burkhan

Pre-Funded

Warrant, in no case would the holder receive less than

2,500,000

shares of BurTech Class A common stock at closing.

On April 22, 2024, the Company amended and restated the Burkhan Pre-funded Warrant to reduce the number of BurTech Class A common stock shares to which the holder is entitled upon exchange of the Company common shares issuable upon exercise of the warrant. The number of BurTech Class A common stock shares was reduced from a maximum of

6,833,333

share to a fixed

2,000,000

shares. This amendment, in turn, reduces the

applicable number of Company common shares to be issued to the holder upon exercise. Additionally, in conjunction with its participation in the Blaize Note Financing Agreement, one of the RT Parties received a new and separate prefunded warrant (the “Ava Pre-funded Warrant”) with an exercise price of $45,000 that entitles the RT Party investor to receive 4,500,000 shares of BurTech Class A common stock, also via the issuance of Company common shares upon exercise that are subject to exchange into BurTech Class A common stock upon the closing of the Merger. The fair value of the newly issued Ava Pre-funded Warrant of $0.5 million was recognized as a debt financing charge on 2023 convertible notes during the year ended December 31, 2024.

All of the Company’s warrants exercisable into preferred stock are classified as liabilities requiring ongoing remeasurement at fair value.

As provided by the terms of the P2P notes, the notes remained outstanding and were converted, at the option of the holders, to common stock upon the execution of the Merger (see Note 1).

(a)

The number of warrant shares to be issued upon exercise of the P2P Warrants is not determined as of December 31, 2024 or 2023, therefore, the exercise price is only known in aggregate based on individual investor participation levels and timing of investment. The aggregate exercise price is $2.5 million as of December 31, 2024 and 2023. The Company’s valuation of its P2P Warrants assumes expected warrant shares of 1,127,088 and a range of 694,397 to 721,086 shares of either common stock or a future preferred stock series as of December 31, 2024 and 2023.

(b)

Common stock warrants represent prior Series D Preferred Warrants which were converted in November 2022 to common stock warrants following the Company’s conversion event, as adjusted for the related December 2022 reverse stock split. These common stock warrants are classified in equity upon conversion in 2022. During January 2023, 336,950 of the Series D Preferred Warrants were reinstated upon the investor participating in the P2P Note extension. These warrants expired during the year ended December 31, 2024.

(c)

The number of warrant shares to be issued upon exercise of the Convertible Note Warrants as well as the related aggregate exercise price is not determinable as of December 31, 2024 and 2023 due to variable settlement terms. As of December 31, 2024 and 2023, the aggregate fixed monetary amount that will serve as the basis of calculating the number of warrant shares into which the Convertible Notes may be exercised into is $13.0 million and $2.0 million, respectively.

(d)

Total exercise price is $68,333. As of December 31, 2023, the number of warrant shares is estimated based on the total Company common shares that would be required to be issued to be exchanged for the maximum number of BurTech Class A Common and is estimated at 7,007,582 shares. As of December 31, 2024, taking into consideration the effect of the April 2024 amendment, the number of warrant shares required to be issued in the form of BurTech Class A Common stock is fixed at 2,000,000 shares.

(e)	Total exercise price is $45,000. As of December 31, 2024, the number of warrant shares to be issued in the form of BurTech Class A Common stock is a fixed 4,500,000 shares.

Net Loss Per Share Attributable to Common Shareholders

Note 17. Net Loss Per Share

The following table sets forth the computation of basic and dilutive net loss per share:


	Three Months Ended March 31,
(Amounts in thousands, except share and per share amounts)	2025			2024
Numerator:
Net loss	$	(147,761	)	$	(16,743	)

Net loss per share, basic and diluted	$	(1.61	)	$	(1.23	)

Net loss per share calculations and potentially dilutive security amounts for all periods prior to the closing of the Merger have been retrospectively adjusted to the equivalent number of shares outstanding immediately after the Merger to effect the reverse recapitalization. Historically reported weighted average shares outstanding have been multiplied by the Exchange Ratio of approximately 0.78.

The following potentially dilutive securities were excluded from the calculation of diluted net loss per share attributable to common shareholders for the periods presented because the impact of including them would have been anti-dilutive:


	Three Months Ended March 31,
	2025		2024
Stock options		28,042,235		12,819,685

Organization and Description of Business	3 Months Ended
Organization and Description of Business	Mar. 31, 2025
Collaborative Arrangement and Arrangement Other than Collaborative [Line Items]
Organization and Description of Business	Note 1. Organization and Description of Business Organization Blaize Holdings, Inc. (together with its subsidiaries, the “Company,” “Blaize,” “we,” “our,” “us,” or the “registrant,”) is headquartered in El Dorado Hills, California, and consists of four separate operating entities: Blaize, Inc. (United States of America), Blaize New Computing Technologies India Private Limited (India), Blaize Technologies Philippines, Inc. (Philippines) and Blaize U.K. LTD (England). Description of Business Blaize designs and develops low-power, high-efficiency, programmable artificial intelligence (“AI”) edge computing hardware and software. The Company leads a new generation of computing, which unleashes the potential of AI in order to enable significant increases in the value that technology delivers to improve the way people work and live. Blaize offers transformative edge computing solutions for AI data collection and processing, with a focus on smart vision and other AI applications for the automotive, retail, security and industrial markets. In November 2023, Blaize entered into a Memorandum of Understanding with a United Arab Emirates (“UAE”) based third-party investment entity to establish a cooperative framework for both entities to discuss and explore commercial and technical collaboration in the UAE. The collaboration is intended to be operationalized through a newly created entity, Blaize Artificial Intelligence Middle East, LLC, in which the Company has a 35% ownership in the entity. As of March 31, 2025, there has not been an operating agreement executed between the Company and the holder of the 65% interest that would make us the primary beneficiary of this new legal entity. The newly established entity has incurred insignificant expenses since its incorporation. In the first quarter of 2025, the U.S. government announced a series of new tariff policies affecting imports from several countries, including China. While these actions impact a range of global trade flows, the new tariffs targeting imports from China are the most significant for our business. While the ultimate implications of the tariffs remain unclear, they could materially increase the Company’s import costs and potentially lead to higher prices that reduce consumer demand. The Company is monitoring the situation closely and is proactively evaluating strategies to mitigate the impact on its supply chain and margins. These efforts include exploring alternative sourcing outside of China, working with our suppliers to manage cost increases, and implementing price increases. These actions that we take may not fully offset the impact of tariffs and, as a result, our revenues, gross margins and overall financial performance may be materially impacted. Merger and Reverse Recapitalization On January 13, 2025 (the “Closing Date”), the Company consummated the transactions (the “Merger”) contemplated by the Agreement and Plan of Merger (the “Merger Agreement”), dated as of December 22, 2023 (as amended on April 22, 2024, October 24, 2024 and November 21, 2024), with BurTech Acquisition Corp. (“BurTech”), BurTech Merger Sub, Inc. (“Merger Sub”), Blaize, Inc. (“Legacy Blaize”), and for the limited purposes set forth therein, Burkhan Capital LLC (“Burkhan”), a Delaware limited liability company and an affiliate of BurTech. On the Closing Date, Merger Sub merged with and into Legacy Blaize, with Legacy Blaize, surviving the Merger as a wholly owned subsidiary of the Company. Concurrent with the Merger, BurTech was renamed Blaize Holdings, Inc. Beginning on January 14, 2025, Blaize’s common stock and warrants trade on Nasdaq under the ticker symbols “BZAI” and “BZAIW”, respectively (see Note 3). Accounting for the Merger The Merger is accounted for as a reverse recapitalization, with BurTech being treated as the acquired company and Legacy Blaize was treated as the acquirer for financial reporting purposes. This accounting treatment is equivalent to Legacy Blaize issuing stock for the net assets of BurTech, accompanied by a recapitalization whereby no goodwill or other intangible assets are recorded. Operations prior to the Merger are those of Legacy Blaize. For periods prior to the Merger, the reported share and per share amounts have been retroactively converted (“Retroactive Conversion”) by applying the Exchange Ratio. Legacy Blaize shareholders were issued 87,314,968 shares of common stock. Prior to the Merger, BurTech LP, LLC was the sponsor (the “Sponsor”, “BurTech LP”) of BurTech and with the close of the Merger, BurTech LP and its affiliated entities, have remained a significant shareholder in Blaize. Emerging Growth Company Status The Company is an emerging growth company, as defined in Section 2(a) of the Securities Act of 1933, as amended, (the “Securities Act”), as modified by the Jumpstart Our Business Startups Act of 2012 (“JOBS Act”). The Company 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 auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a non-binding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act, until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that we (i) are no longer an emerging growth company or (ii) affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, these condensed consolidated financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates. Liquidity and Going Concern The Company’s condensed consolidated financial statements have been prepared on a going concern basis, which assumes that it will be able to meet its obligations and continue its operations during the twelve months following the issuance of these condensed consolidated financial statements. These condensed consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classifications of liabilities that may result should we be unable to continue as a going concern. Since the inception of the Company and through March 31, 2025, the Company has funded its operations primarily with cash flows from contributions from founders or other investors and other financing activities. The Company has incurred recurring losses and negative cash flows since its inception, including net losses of $147.8 million and $16.7 million for the three months ended March 31, 2025 and 2024, respectively. As of March 31, 2025, the Company had cash and cash equivalents of approximately $45.0 million, and an accumulated deficit of $577.0 million. The Company’s ability to continue to meet its obligations, to achieve its business objectives and continue as a going concern is dependent upon several factors, including its revenue growth rate, the timing and extent of spending to support further sales and marketing and research and development efforts. In order to finance these opportunities, the Company will need to raise additional financing. While there can be no assurances, the Company intends to raise such capital through issuances of additional debt and equity. If additional financing is required from outside sources, the Company may not be able to raise it on terms acceptable to it or at all. If the Company is unable to raise additional capital when desired, its business, results of operations and financial condition would be materially and adversely affected. As a result of the above, in connection with its assessment of going concern considerations in accordance with Financial Accounting Standard Board’s (“FASB”) Accounting Standards Update (“ASU”) 2014-15, Disclosures of Uncertainties about an Entity’s Ability to Continue as a Going Concern , management has determined that the Company’s liquidity condition raises substantial doubt about its ability to continue as a going concern through one year from the date that these condensed consolidated financial statements are issued.

Redeemable Convertible Preferred Stock Prior to the Merger

Note 11. Redeemable Convertible Preferred Stock Prior to the Merger

Under the terms of the December 12, 2022 Amended and Restated Certificate of Incorporation, the Company introduced “Shadow Preferred” classes of stock. A Shadow Preferred class of stock was created for each series of preferred stock outstanding prior to the conversion. Those shareholders who participated in the Company’s December 2022 P2P Transaction obtained the benefit of a pull-through exchange of their converted common stock which provided for participating shareholders to receive shares of the class(es) of Shadow Preferred Stock identical to the shares of preferred stock that they previously held. Investors who did not participate, retained ownership only in converted common stock.

Upon the consummation of the Merger, the redeemable convertible preferred stock that was outstanding at the time of the Merger was converted into shares of common stock (see Note 3).

Note 10. Redeemable Convertible Preferred Stock

Under the terms of the December 12, 2022 Amended and Restated Certificate of Incorporation the Company introduced “Shadow Preferred” classes of stock. A Shadow Preferred class of stock was created for each series of preferred stock outstanding prior to the conversion. Those shareholders who participated in the Company’s December 2022 P2P Transaction obtained the benefit of the Pull-Through Exchange of their Converted Common into shares of the class(es) of Shadow Preferred Stock identical to those previously held (see Note 7). Investors who did not participate, retained ownership only in Converted Common stock.

February 2023

, the Company raised $

9.4

million in additional P

P Notes, inclusive of $

0.1

million in proceeds from the Common Rights Offering (see Notes

and

13)

. Those shareholders who participated in providing additional funding in

2023

obtained the benefit of the Pull-Through Exchange of their Converted Common into shares of the class(es) of Shadow Preferred Stock identical to those previously held (see Note

. Investors who did not participate retained ownership only in Converted Common stock. For the year ended December

2023

, the Pull-Through Exchange resulted in incremental value to the investors in the P

P Notes of $

30.6

million, measured as the difference in the fair value of the Shadow Preferred Stock shares held after the Pull-Through Exchange to the fair value of the Converted Common held just prior to the Pull-Through Exchange, which has been accounted for as a

Pay-to-Play

financing charge in the consolidated statements of operations.

prior and in preference to any dividends on the Series Seed Preferred Stock, Series A Preferred Stock and Common

Stock, at the rate of $0.0552 per annum for each share of Series B Preferred Stock and $0.3812 per annum for each share of Series C Preferred Stock, on a

non-cumulative

days of the Redemption Request in

three

annual installments so long as the total redemption amount does not exceed

% of the Company’s then current enterprise value.

The redemption request could not be made until after the fifth anniversary of the date upon which shares of the Series C Preferred Stock are first issued, or July 2023. Such request was not made as of such date (see Note 7).

Due to conditions of redemption that are outside the control of the Company, the redeemable convertible preferred stock has been reflected outside of stockholders’ deficit.

Conversion

The holders of the preferred stock have a right to convert their stock into shares of common stock at any time after the date of issuance and on the fifth day prior to the Redemption Date. Each share of preferred stock shall be convertible to common stock, the rate of which is determined by dividing the applicable Original Issuance Price for such series by the applicable “Conversion Price” (defined as Original Issuance Price applicable to such series, subject to certain adjustments as define in Section 4(d) of the Restated Certificate of Incorporation).

In addition, each share of Preferred Stock shall automatically be converted into shares of Common Stock at the Conversion Rate immediately upon the earlier of (i) an IPO with resulting gross proceeds of at least $150.0 million, (ii) a Qualified Direct Listing, (ii) a Qualified SPAC Transaction with cash and cash equivalents of at least $225.0 million after redemptions or (iv) upon vote or written consent or agreement of the holders of a majority of the then outstanding shares of Preferred Stock voting as a single class on an

as-converted

basis.

If there is a recapitalization of the Common Stock, provision shall be made so that the holders of the Preferred Stock shall be entitled to receive upon conversion of the Preferred Stock, the number of shares of stock, or other securities or property of the Company, to which a holder of Common Stock deliverable upon conversion would have been entitled on such recapitalization.

On the Closing Date, all outstanding preferred stock was converted to common stock upon the execution of the Merger (see Note 1).

Total net deferred tax assets	$	2,157		$	1,033

In determining the need for a valuation allowance, the Company weighs both positive and negative evidence in the various jurisdictions in which it operates to determine whether it is more likely than not that deferred tax assets are recoverable. In assessing the ultimate realizability of its net deferred tax assets, the Company evaluates all available objective evidence, including the cumulative losses and expected future losses and as such,

management does not believe it is more likely than not that the net deferred tax assets will be realized. Accordingly, a full valuation allowance has been established in the U.S. and the Philippines. As of December 31, 2024 and 2023, the valuation allowance was $

75.8

million and $

60.9

million, respectively. The increase of $

14.9

million in the Company’s valuation allowance as of December 31, 2024 compared to the prior year was primarily due to an increase in deferred tax assets arising from capitalized research and experimental expenditures and net operating losses.

At December

31, 2024, the Company had U.S. federal net operating loss (“NOL”) carryforwards of $

215.5

million and U.S. state NOL carryforwards of $

149.9

million. The U.S. federal NOL carryforwards will begin to expire in the year 2030 and the state NOL carryforwards will also begin to expire in the year 2030. As of December 31, 2024, the Company had federal tax credit carryforwards of $

5.7

million available to offset future U.S. federal income taxes payable, which will begin to expire in the year 2035. As of December 31, 2024, the Company had state tax credit carryforwards of $

4.3

million available to offset future state income taxes payable and foreign tax credits of $

97.2

million available to offset future India income taxes payable.

The Company’s ability to utilize the net operating loss and tax credit carryforwards in the future may be subject to substantial restriction in the event of past or future ownership changes as defined in Section 382 of the Internal Revenue Code and similar state tax laws. In the event the Company should experience an ownership change, as defined, utilization of its net operating loss carryforwards and tax credits could be limited. Due to the existence of the valuation allowance, future changes in the Company’s unrecognized tax benefits will not impact its effective tax rate. Any carryforwards that will expire prior to utilization as a result of such limitations will be removed from deferred tax assets with a corresponding reduction of the valuation allowance.

It is the Company’s policy to include penalties and interest expense related to income taxes as a component of income tax expense. Management determined that no accrual for interest and penalties was required as of December 31, 2024 and 2023.

The Company’s primary tax jurisdictions are the United States, United Kingdom and India. All tax years since inception remain open to examination by the U.S. federal authorities as a result of the net operating losses and credit carryforwards since inception. The Company is not currently under income tax examinations in any foreign or state jurisdiction.

It is the Company’s policy to indefinitely reinvest undistributed earnings of their foreign subsidiaries and hence, no deferred tax liability for withholding taxes on undistributed earnings is required.

Uncertain Tax Positions

The Company applied FASB ASC

740-10-50,

Accounting for Uncertainty in Income Tax

, which prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return.

The Company had unrecognized tax benefits of approximately $

5.0

million and $

4.3

million as of December 31, 2024 and 2023, respectively. ASC

740-10

prescribes a comprehensive model for the recognition, measurement, presentation and disclosure in financial statements of any uncertain tax positions that have been taken or expected to be taken on a tax return. The amount of unrecognized tax benefits is not expected to significantly change over the next twelve months. No amounts, outside of valuation allowance, would impact the effective tax rate on continuing operations.

The beginning and ending unrecognized tax benefits amounts is as follows as of December 31, 2024 and 2023 (in thousands):


	2024		2023
Unrecognized tax benefits, beginning of period	$	4,283	$	3,811
Additions based on tax positions taken related to prior years		12		—
Additions based on tax positions taken related to current period		705		472

Segment Reporting Information [Line Items]

Segment Reporting

Note 16. Segment Reporting

The Company operates as a

single

reportable segment, and manages the business and evaluates financial performance on a consolidated basis. The CODM regularly receives and reviews consolidated financial results

focusing primarily on revenue, costs and expenses, and net loss from the consolidated statements of operations to make decisions regarding the allocation of resources and assessment of performance.

The Company has determined that net loss and earnings before interest, tax, depreciation and amortization (“EBITDA”) adjusted for irregular or

non-recurring

items (“Adjusted EBITDA”) are the profit or loss measures that the CODM uses to make resource allocation decisions and evaluate segment performance. Adjusted EBITDA assists management in comparing the performance on a consistent basis for purposes of business decision-making by removing the impact of certain items that management believes do not directly reflect our core operations and, therefore, are not included in measuring performance. The Company defines Adjusted EBITDA as net loss before interest, taxes, depreciation and amortization, certain

non-cash

items and other adjustments that we do not consider in our evaluation of ongoing operating performance from period to period.

Net loss is as follows:


	Three Months Ended March 31,
(Amounts in thousands)	2025			2024
Revenue	$	1,007		$	549
Cost of revenue		(327	)		(306	)
Employee costs		(19,081	)		(5,700	)
Technology costs		(2,417	)		(360	)
Depreciation and amortization		(191	)		(253	)
Net interest (income)/expense		399			(229	)
Fair value changes and financing charges		(109,530	)		(8,166	)
Other segment items (a)		(17,621	)		(2,278	)

Net loss	$	(147,761	)	$	(16,743	)

(a)	Other segment items includes marketing expense, professional fees, income tax expense, facilities costs, foreign currency exchange gains and losses, credit loss expense, and other overhead expenses

The following reflects our Adjusted EBITDA:


	Three Months Ended March 31,

Net loss	$	(147,761	)	$	(16,743	)

Other non-recurring expenses (a)		12,035			45

Adjusted EBITDA	$	(15,380	)	$	(7,527	)

(a)

Includes, but not limited to, legal, accounting and consulting fees incurred in connection with the Merger. These costs are

non-recurring

and are not reflective of our ongoing operating performance. Management believes that excluding these costs provides a more meaningful comparison of our performance to prior periods.

The measure of segment assets is reported on the condensed consolidated balance sheet as total consolidated assets. Long-lived and ROU assets were located as follows:

Employee Benefit Plan [Abstract]
Employee Benefit Plan	Note 18. Employee Benefit Plan A 401(k) plan is provided that covers substantially all employees in the US meeting certain age and service requirements. The Company makes discretionary contributions to the 401(k) plan. The Company operates a defined contribution pension scheme in the UK for employees and makes employer contributions to this scheme on behalf of those employees. The Company recorded $0.2 million and $0.1 million in contributions to both plans during the three months ended March 31, 2025 and 2024, respectively. Long-term Employee Benefits The Company provides its employees in India an opportunity to participate in a long term defined benefits plan, and the liability the Company bears for providing this benefit is determined through an actuarial valuation at each reporting date. The benefit plan provides for lump sum payments to vested employees on retirement, death while in service or on termination of employment for an amount equivalent to 15 days of basic salary for each completed year of service. Vesting occurs upon completion of five years of service. The present value of such obligation is determined by the projected unit credit method and adjusted for past service cost and fair value of plan assets as at the balance sheet date through which the obligations are to be settled. The actuarial gain or loss on change in present value of the defined benefit obligation or change in return of the plan assets is recognized as an income or expense in the condensed consolidated statement of operations. The expected return on plan assets is based on the assumed rate of return of such assets. As of March 31, 2025 and December 31, 2024, the related liability is included within accrued compensation on the condensed consolidated balance sheets.	Note 15.

SUBSEQUENT EVENTS	Note 19. Subsequent Events The Company has evaluated subsequent events through the date on which these condensed consolidated financial statements were available to be issued, and determined that the following subsequent events, other than those disclosed elsewhere in the condensed consolidated financial statements, are reportable: On April 11, 2025, the Company entered into an advisory agreement for future services. The terms of the agreement require a non-refundable advisory fee of $2.0 million paid upon execution of the contract in the form of 769,231 shares of common stock (the “Fee Shares”). The Fee Shares are subject to a one-year lock up provision (the “Lock-Up Period”) which expires the earlier of one year from the date of the agreement or the date of a change of control as defined in the agreement. Prior to the expiration of the lock-up period, the advisor may sell the common stock shares back to us or an affiliate as defined in Rule 405 under the Securities Act. The Fee Shares subject to the lock-up provision are subject to adjustment if the dollar volume-weighted average price for the Company’s common stock (“VWAP”) 20 out of any 30 trading Days is at least $7.00 per share, then the Lock-Up Period shall be terminated with respect to fifty percent of the shares to be issued for the fee.

Merger and Reverse Recapitalization

3 Months Ended

Mar. 31, 2025

Business Combination, Asset Acquisition, and Joint Venture Formation [Abstract]

Merger and Reverse Recapitalization

Note 3. Merger and Reverse Recapitalization

As discussed above, the Merger was consummated on January 13, 2025, which, for accounting purposes, was treated as the equivalent of Legacy Blaize issuing stock for the net assets of BurTech, accompanied by a recapitalization (see Note 1). Under this method of accounting, BurTech was treated as the acquired company for financial accounting and reporting purposes under U.S. GAAP.

Upon the consummation of the Merger, each share of Legacy Blaize common stock issued and outstanding was canceled and converted into the right to receive approximately 0.78 shares (the “Exchange Ratio”) of common stock of BurTech.

Legacy Blaize Redeemable Convertible Preferred Stock, Convertible Promissory Notes and Warrants

Immediately prior to the closing of the Merger, all outstanding convertible notes, inclusive of accrued and unpaid interest, each of the issued and outstanding shares of redeemable convertible preferred stock, and all outstanding warrants, net exercised, were automatically converted into shares of common stock.

Upon the consummation of the Merger, (i) each outstanding stock option to purchase Legacy Blaize common stock was converted into a stock option of the Company, upon substantially the same terms and conditions as in effect with respect to the corresponding Legacy Blaize option, and the right to receive a number of earnout shares. Additionally, each Legacy Blaize RSU was converted into an RSU of the Company, upon substantially the same terms and conditions as in effect with respect to the corresponding Legacy Blaize RSU, and the right to receive a number of earnout shares.

Other Arrangements entered into at time of Merger or assumed upon the consummation of the Merger:

Public and Private Placement Warrants

Upon the consummation of the Merger, BurTech’s 28,750,000 public warrants and 898,250 private warrants, both outstanding immediately prior to the consummation of the Merger, became warrants of the Company.

PIPE Shares

From December 31, 2024 through January 13, 2025, BurTech and certain other subscribers (collectively, the “Subscribers”) entered into subscription agreements under which BurTech agreed to issue and sell to the Subscribers, immediately before the Closing Date, collectively, 1,529,500 shares of Class A Stock (the “PIPE Shares”) at a price per share equal to $10.00. Such shares that were outstanding immediately prior to the Merger became shares of common stock.

Shareholder Note Receivable

Upon the consummation of the Merger, BurTech LP issued a secured promissory note and pledge agreement (the “Shareholder Note”) to BurTech in the principal amount of $8,753,744 in exchange for 750,000 shares of common stock. The principal of the Shareholder Note will decrease when BurTech LP pays for transaction costs that the Company assumed from BurTech in the Merger. The Shareholder Note bears interest at 7.0%, compounding annually on December 31 of each year and is secured by 2,000,000 shares of the Company’s common stock owned by BurTech LP.

Non-Redemption

Agreements

On December 31, 2024 and through January 13, 2025, BurTech, BurTech LP and Legacy Blaize entered into

Non-Redemption

Agreements with several unaffiliated stockholders of BurTech (each, an “Investor”) who agreed not to redeem (or validly rescind any redemption requests on) their shares of common stock

(“Non-Redeemed

Shares”). These

Non-Redeemed

Shares were exchanged for shares of the Company’s common stock and are held in a separate escrow account. In exchange for the foregoing commitments not to redeem the

Non-Redeemed

Shares, the Company and BurTech LP agreed to guarantee that each Investor receives a return of $1.50 per

Non-Redeemed

Share above the initial $11.57 per share (for a total redemption value of $13.07 per

Non-Redeemed

Share) held in the related cash escrow account if the Investor sells the

Non-Redeemed

Shares in the open market. The funds in the related cash escrow account are sufficient to fulfill the Company’s redemption obligation under the

Non-Redemption

Agreement. Starting 90 days after the Closing Date through 180 days after

the Closing Date, each Investor has the right to exercise a put option to receive $13.07 per

Non-Redeemed

Share. The Sponsor, and not the Company, is contractually obligated for the $1.50 per share above the $11.57 held in cash escrow as it relates to the put option. Accordingly, the Company did not recognize a

non-redemption

liability as of the Closing Date or March 31, 2025.

The following table reconciles the elements of the Merger to the condensed consolidated statement of cash flows and the condensed consolidated statement of stockholders’ equity (deficit) for the three months ended March 31, 2025:

Earnout Arrangement with holders of Legacy Blaize Common Stock and outstanding equity awards

Legacy Blaize shareholders and outstanding equity award holders (including stock options and RSUs) are entitled to Earnout Shares in four tranches upon the occurrence of four separate Triggering Events (defined below) during the Earnout Period, which commences on January 13, 2025 and ends on January 13, 2030. The Triggering Events are driven by whether the Company’s closing share price on 20 trading days out of 30 consecutive trading days equals or exceeds defined per share thresholds in each tranche as follows:

•

If the Company’s common stock price is greater than or equal to $12.50 per share, 3,750,000 Earnout Shares will be issued; and

•

If the Company’s common stock price is greater than or equal to $15.00 per share, an additional 3,750,000 Earnout Shares will be issued; and

•

If the Company’s common stock price is greater than or equal to $17.50 per share, an additional 3,750,000 Earnout Shares will be issued; and

•

If the Company’s common stock price is greater than or equal to $20.00 per share, an additional 3,750,000 Earnout Shares will be issued

Company employees entitled to receive Earnout Shares with respect to Blaize options and RSUs, must provide service through the date the target is achieved and if an employee departs, the Earnout Shares are reallocated to the remaining pool of recipients who received the right to the Earnout Shares on the Closing Date.

The estimated fair value of the Earnout Shares subject to ASC 718 was $82.9 million, assuming the service conditions were met and assuming no forfeitures. The vested amounts of $3.5 million for the three months ended March 31, 2025 were recorded as stock-based compensation expense as it was probable the market condition would be met. There were 37,090 shares forfeited during the three months ended March 31, 2025, which have been reallocated to the remaining employees. The reallocated shares are considered a forfeiture of the original award and grant of a new award. The new awards have been remeasured upon grant and have an estimated fair value of $33 thousand. Each Triggering Event, as defined, is considered a market condition. The requisite service condition is the period of time it takes to achieve all four market conditions. As this is not explicitly stated in the earnout arrangement, the service period is implied from the expected period over which the shares are expected to achieve the market condition. Under this guidance, the award is measured at fair value at the grant (or issue) date using the Monte Carlo simulation model and expense is recognized over the derived service period of 5 years.

Additionally, Burkhan has the right to receive up to an aggregate amount of 2,600,000 shares of Blaize Class A Common Stock, 650,000 following the occurrence of each triggering event stated above (the “Burkhan Earnout Shares”). The fair value of the Burkhan Earnout Shares are also valued using the Monte Carlo simulation model.

Pursuant to this promissory note, BurTech LP agreed to pay certain of the transaction expenses (as defined in the Merger Agreement) of BurTech. As consideration for this promissory note, the Company issued 750,000 shares of common stock to BurTech LP.

Convertible Notes and Demand Notes

Note 8. Convertible Notes and Demand Notes

Pay-to-Play

Convertible Notes

In December 2022, in connection with the Company’s 2022

Pay-to-Play

(“P2P”) transaction (the “P2P Transaction”), the Company entered into a Note Purchase and Exchange Agreement (“2022 P2P NPA”) with a group of lenders (each, a “Lender” and collectively, the “Lenders”). In January and February of 2023, the Company received $9.3 million in proceeds from the issuance of P2P Notes. Amounts received in 2022 and 2023 are referred to collectively as the “P2P Notes” (see Note 15). Pursuant to the 2022 P2P NPA, each Lender will pay the Company an agreed upon amount (“Consideration”) in return for one or more promissory notes. The P2P Notes had an initial

24-month

term from the date of the 2022 P2P NPA which is December 9, 2024.

The 2022 P2P NPA provided that the P2P Notes would be converted upon the consummation of the Merger and that, at such time, all outstanding principal and unpaid accrued interest due on the P2P Notes shall be converted into common stock.

The Company elected to measure the P2P Notes in their entirety, for the respective period issued, at fair value with changes in fair value reported in a single line in the condensed consolidated statements of operations. The notes were fair valued using a scenario-based method, considering varying levels of participation and four future event scenarios: Next Equity Financing, Maturity Conversion, Corporate Transaction, and Default. The conversion payout was calculated for each assumed event scenario, with probabilities estimated by management. The payout of the P2P Notes under each event scenario were discounted back to the valuation date using a

discount rate aligned with the Company’s credit rating and the weighted average present value of each scenario used for the fair value of the P2P Notes. Upfront costs and fees related to items for which the fair value option is elected must be recognized immediately. As such issuance costs (warrants) and fees associated with the convertible notes were recognized in current earnings.

Under the terms of the 2022 P2P NPA, any existing investor that purchased any P2P Note, received the right to exchange the common stock held following the November 30, 2022 conversion event, for a number of shares of shadow preferred stock mirroring the respective classes of preferred stock held prior to the conversion (the “Pull-Through Exchange”), however, all Senior Series D shareholders received an automatic pull-through of their converted common stock into their respective Senior Series D Shadow preferred stock regardless of whether they invested in a P2P Note. The exchange was calculated using a defined “Exchange Formula” based on the existing investor’s amount of investment in the P2P Note in relation to the designated

pro-rata

share portion of the Insider Amount. To the extent that an eligible existing investor purchases P2P Notes representing less than its pro rata portion of the Insider Amount, such investors converted common stock remain as converted common stock for that portion equal to the shortfall in its

pro-rata

contribution. Additionally, investors in the P2P Notes also received warrants (the “P2P Warrants”) whose total exercise price is determined based on the timing of investment as well as the level of investor participation

vis-à-vis

each investor’s designated

pro-rata

portion.

In November 2023, the Company entered into an Exchange Agreement with eligible common shareholders, as defined, whereby, each participating eligible common shareholder received a P2P Note, subject to the same terms as existing P2P Notes with the exception that the P2P Notes issued to these common shareholders did not include the right to receive P2P Warrants. Proceeds received under the Offering totaled $0.1 million.

Upon the consummation of the Merger, as provided by the terms of the P2P notes, the outstanding P2P Notes were converted, at the discretion of the holders, to shares of common stock (see Note 3).

2023 Convertible Notes

From July 2023 through November 2023, the Company raised $12.3 million in convertible notes (the “2023 Convertible Notes”) under the note purchase agreement dated July 3, 2023, as amended on August 1, 2023 to refine the valuation cap definition (the “2023 NPA”). The 2023 Convertible Notes accrued interest at 10.0% per annum.

During the year ended December 31, 2024, the Company received $110.7 million in additional proceeds from the issuance of 10% secured convertible notes under the 2023 NPA. The 2023 NPA was amended and restated on April 22, 2024 to accommodate a new group of lenders, the “Final Closing Lenders”, defined as any lender who purchases a related convertible note on or after April 22, 2024. The conversion price upon a SPAC Transaction for a Final Closing Lender is defined as a price per share that would entitle the Final Closing Lender to receive a number of BurTech Class A common stock equal to the outstanding principal and accrued interest divided by five. In addition, the per share exercise price of the related 2023 Convertible Note Warrants upon a SPAC Transaction was amended to $11.50.

As of the April 22, 2024 amendment, the convertible notes were subject to automatic conversion upon the consummation of a SPAC Transaction. Investors in these secured convertible notes also received warrants to purchase equity shares of the Company.

Of the $110.7 million in proceeds received during the year ended December 31, 2024, $11.5 million was received from BurTech (see Note 1), $2.4 million from miscellaneous parties, and $96.8 million from a separate third-party group of investors (the “RT Parties”) in connection with an agreement to provide convertible note

financing of up to $125.0 million (the “Blaize Note Financing Agreement”). Under this separate agreement, the RT Parties and their transferees or distributes were not required to execute any

lock-up

or similar agreement restricting transfer or disposition of all shares of common stock of Blaize issuable upon the conversion of the notes, all Company shares issuable upon the exercise of warrants issued to the RT Parties as well as all securities of New Blaize to be issued to the RT Parties upon consummation of the Merger.

The Company elected to measure the 2023 Convertible Notes in their entirety at fair value with changes in fair value reported in a single line in the condensed consolidated statements of operations. The 2023 Convertible Notes were fair valued using a scenario-based method, considering five future event scenarios: Next Equity Financing, Maturity Conversion, SPAC Conversion, Corporate Transaction, and Default. The conversion payout was calculated for each assumed event scenario, with probabilities estimated by management. The payout of the 2023 Convertible Notes under each event scenario were discounted back to the valuation date using a discount rate aligned with the Company’s credit rating and the weighted average present value of each scenario used for the fair value of the 2023 Convertible Notes.

Upfront costs and fees related to items for which the fair value option is elected must be recognized immediately. As such issuance costs (warrants) and fees associated with the convertible notes were recognized in earnings in the years that they were issued.

One investor who purchased a 2023 Convertible Note also received an RSU grant for a total of 6,000,000 RSUs (see Note 15) which vested in full in the year ended December 31, 2023.

Upon the consummation of the Merger, as provided by the terms of the 2023 Convertible Note Agreement, the outstanding 2023 Convertible Notes were converted, at the discretion of the holders, to shares of common stock (see Note 3). The warrants issued in conjunction with the 2023 Convertible Notes were not exercised.

Working Capital Loan

On February 1, 2023, BurTech issued an unsecured convertible promissory note to BurTech LP (the “Working Capital Loan”), pursuant to which it borrowed $1.5 million for general corporate purposes. Such loan may, at BurTech LP’s discretion, be converted into shares of common stock, the number of shares of which will be determined by dividing the sum of the outstanding principal amount by $10.00. The Working Capital Loan will not bear interest and will be repayable, if not converted or repaid on the effective date of the Merger. The maturity date of the Working Capital Loan may be accelerated upon the occurrence of an event of default (as defined under the Working Capital Loan). As of March 31, 2025 and December 31, 2024, the Company had outstanding Working Capital Loans of $1.5 million and zero, respectively.

Advances from Related Party

As of January 13, 2025, BurTech LP provided working capital and extension deposits on behalf of the BurTech. These amounts are reflected on the condensed consolidated balance sheets as advances from related party. The advances are

non-interest

bearing and payable on demand. As of March 31, 2025 and December 31, 2024, the Company had outstanding advances from the related party in the amount of $2.9 million and zero, respectively.

Convertible

Notes and Demand Notes

2022 Convertible Securities:

Pay-to-Play

Convertible Notes:

In December

2022, in connection with the Company’s 2022

Pay-to-Play

9.3

million in proceeds from the issuance of P2P Notes. Amounts received in 2022 and 2023 are referred to collectively as the “P2P Notes” (see Note 13). Pursuant to the 2022 P2P NPA, each Lender will pay the Company an agreed upon amount (“Consideration”) in return for one or more prom

sory notes. The

P2P

Notes have a

24-month

term from the date of the 2022 P2P NPA which is

December 9, 2024

The 2022 P2P NPA provides that the P2P Notes may be converted as follows:

•

Automatically upon a “Next Equity Financing” assuming a Corporate Transaction (as defined), Maturity Conversion (as defined) or repayment has not occurred wherein the Next Equity Financing is defined as the next sale of Company equity securities, including warrants, other than Series

D-2

Preferred stock or warrants to purchase Series

D-2

preferred stock, following the date of the 2022 P2P NPA for the purpose of raising capital with gross proceeds of at least $

million excluding the P2P Notes.

•

If the Next Equity Financing conversion, Corporate Transaction conversion or repayment of the outstanding principal and unpaid accrued interest has not occurred on or before the maturity date (December 9, 2024), the principal and unpaid accrued interest of each P2P Note shall, at the written election of the Requisite Noteholders (holders of a majority interest in the aggregate outstanding principal amount of the P2P Notes) and the Company, pursuant to mutually agreed-upon terms, be automatically converted (the “Maturity Conversion”) into a class of equity shares subject to mutual agreement between the Lenders and the Company.

•

In the event of a Corporate Transaction (any “Liquidation Event” as defined in the existing Certificate of Incorporation), the P2P Notes shall either be repaid or, at the option of the Requisite Noteholders, converted. If conversion is elected upon a Corporate Transaction, the 2022 P2P NPA provides that all outstanding principal and unpaid accrued interest due on the P2P Notes shall be converted into common stock.

•

If upon a Corporate Transaction, repayment is elected by the Requisite Noteholders, the amount of the outstanding P2P Note balance will be repaid based on (i) whether or not the Lender provided consideration less than, equal to or greater than their Pro Rata Portion (calculated as the percentage ownership in Preferred Stock held by the lender) of $20 million (the “Insider Amount”) by (2) the date of Contribution being either prior to November 30, 2022 (the “Initial Commitment Date”) or February 24, 2023 (“Final Closing date”).

•

New Lenders will receive payment equal to the then accrued and unpaid interest plus one and a half times (1.5X) the then outstanding principal, plus two times (2X) the outstanding principal (with respect only to the outstanding principal in excess of $1 million but less than $5 million), as applicable, plus three times (3X) the outstanding principal with respect only to the outstanding principal in excess of $5 million on the P2P Note.

Certain Lenders, who are also a holder of one or more P2P Notes, by either the Initial Commitment Date or the Final Closing Date, may also be entitled to receive warrants (“P2P Warrants”) to purchase equity securities of the Company, upon surrendering their P2P Notes to the Company, the number of which is to be determined by the type of shares into which the P2P Notes are converted as well as the level of investment. The Warrants will be exercisable, in whole or in part, during the term commencing on the date of issuance and ending December 9, 2025 (see Notes 8 and 13).

The

Company elected to measure the P2P Notes in their entirety, for the respective period issued, at fair value with changes in fair value reported in a single line in the consolidated statements of operations. The notes were fair valued using a scenario-based method, considering varying levels of participation and four future event scenarios: Next Equity Financing, Maturity Conversion, Corporate Transaction, and Default. The conversion payout was calculated for each assumed event scenario, with probabilities estimated by management. The payout of the P2P Notes under each event scenario were discounted back to the valuation date using a discount rate aligned with the Company’s credit rating and the weighted average present value of each scenario used for the fair value of the P2P Notes. For the years ended December 31, 2024 and 2023, the Company recognized a change in fair value from the P2P Notes of approximately $

1.3

million and $

2.6

million, respectively (see Notes 4 and 13). Upfront costs and fees related to items for which the fair value option is elected must be recognized immediately. As such issuance costs (warrants) and fees associated with the convertible notes were recognized in current earnings.

Under the terms of the 2022 P2P NPA, any existing investor that purchased any P2P Note, received the right to exchange the common stock held following the November 30, 2022 conversion event (the “Converted Common”) for a number of shares of shadow preferred stock mirroring the respective classes of preferred stock held prior to the conversion (the “Pull-Through Exchange”), however, all Senior Series D (see Note 10) shareholders received an automatic pull-through of their Converted Common into their respective Senior Series D Shadow preferred stock regardless of whether they invested in a P2P Note. The exchange was calculated using a defined “Exchange Formula” based on the existing investor’s amount of investment in the P2P Note in relation to the designated

pro-rata

share portion of the Insider Amount. To the extent that an eligible existing investor purchases P2P Notes representing less than its pro rata portion of the Insider Amount, such investors Converted Common remain as Converted Common shares for that portion equal to the shortfall in its

pro-rata

contribution (see Note 10). Additionally, investors in the P2P Notes also received warrants (the “P2P Warrants”) whose total exercise price is determined based on the timing of investment as well as the level of investor participation

vis-à-vis

each investor’s designated

pro-rata

portion (see Note 8).

During the year ended December 31, 2023, certain investors who previously had their preferred stock and Series D warrants converted to common stock and common stock warrants, respectively, in connection with the 2022 conversion event, invested in P2P Notes. The resulting Pull-Through Exchange reinstated their Converted Common stock into share of the class(es) of Shadow Preferred Stock identical to those held prior to the 2022 conversion event (See Note 10) and reinstated their warrants into Series D Shadow preferred stock warrants (see Note 8). The fair value of the Series D warrants at reinstatement, approximating $

61,000

, was recognized as a component of the

Pay-to-Play

financing charge for the year ended December 31, 2023.

The 2022 P2P NPA provided the Company a right, subject to the approval of the Company’s Board of Directors (the “Board”), to conduct a common rights offering (the “Offering”) to raise additional funds. Pursuant to the 2022 P2P NPA, at the discretion of the Board, the Company could issue either shares of common stock or additional P2P Notes. In November 2023, the Company entered into an Exchange Agreement with eligible common shareholders, as defined, whereby, each participating eligible common shareholder received a P2P Note, subject to the same terms as existing P2P Notes with the exception that the P2P Notes issued to these common shareholders did not include the right to receive P2P Warrants. Proceeds received under the Offering totaled $

0.1

million. In addition to the P2P Note, each participating eligible common shareholder also received the right to have the number of common shares held immediately prior to the Offering restored to the total number of common shares held prior to the Company’s

2022 reverse stock-split. For the year ended December 31, 2023, this restoration of common shares resulted in incremental value to the participating eligible common investors of $5.2 million, measured as the fair value of the incremental common shares received or restored following the Offering. This incremental value has been accounted for as a

Pay-to-Play

financing charge in the accompanying consolidated statements of operations. During the year ended December 31, 2024, the Company did not enter into any Exchange Agreements with eligible common shareholders.

On the Closing Date, as provided by the terms of the P2P notes, the outstanding P2P Notes were converted, at the option of the holders, to common stock upon the execution of the Merger (see Note 1).

2023 Convertible Notes:

From July 2023 through November 2023, the Company raised $

12.3

million in convertible notes (the “2023 Convertible Notes”) under the note purchase agreement dated July 3, 2023, as amended on August 1, 2023 to refine the valuation cap definition (the “2023 NPA”) (see Note 13). The 2023 Convertible Notes accrue interest at

% per annum and mature

months from the date of the 2023 NPA. The 2023 Convertible Notes are secured by all of the Company’s assets.

During

the year ended December 31, 2024, the Company received $

110.7

million in additional proceeds from the issuance of

% secured convertible notes under the 2023 NPA. The 2023 NPA was amended and restated on April 22, 2024 to accommodate a new group of lenders, the “Final Closing Lender”, defined as any lender who purchases a related convertible note on or after April 22, 2024. The conversion price upon a SPAC Transaction for a Final Closing Lender is defined as a price per share that would entitle the Final Closing Lender to receive a number of BurTech Class A common stock equal to the outstanding principal and accrued interest divided by five (5). In addition, the per share exercise price of the related 2023 Convertible Note Warrants upon a SPAC Transaction was amended to $

11.50

As of the April 22, 2024 amendment, the convertible notes have a stated maturity date of December 31, 2025, and are subject to automatic conversion upon the consummation of a SPAC Transaction, as defined, subject to conversion or repayment at maturity or upon a Next Equity Financing, as defined, and are subject to repayment upon a Corporate Transaction, as defined. Investors in these secured convertible notes also received warrants to purchase equity shares of the Company.

he $

110.7

million in proceeds received during the year ended December 31, 2024, $

11.5

million was received from BurTech (see Note 1), $

2.4

million from miscellaneous parties, and $

96.8

million from a separate third-party group of investors (the “RT Parties”) in connection with an agreement to provide convertible note financing of up to $

125.0

million (the “Blaize Note Financing Agreement”). Under this separate agreement, the RT Parties and their transferees or distributes will not be required to execute any

lock-up

The 2023 NPA provides that the notes may be converted as follows:

•

Automatically upon a “Next Equity Financing” assuming a Corporate Transaction (as defined), Maturity Conversion (as defined), SPAC Conversion (as defined) or repayment has not occurred wherein the Next Equity Financing, defined as the next sale of Company equity securities or other securities issued in connection with Senior Indebtedness, following the date of the 2023 Convertible Notes for the purpose of raising capital.

•

For Lenders who purchased a 2023 Convertible Note on or before July 3, 2023, the issuance of shares pursuant to the conversion of each note shall be subject to the same terms and conditions applicable to the equity securities sold in the Next Equity Financing, except that (A) the per share liquidation preference shall be 1.5 times the conversion price, (B) the initial conversion price for purposes of price-based anti-dilution protection will equal the conversion price, (C) the basis for any dividend rights will be based on the conversion price, and (D) such shares will rank senior to the other equity securities existing at the time of the applicable conversion with respect to liquidation preference.

•

For any Lender who purchased a 2023 Convertible Note after July 3, 2023, the issuance of shares pursuant to the conversion of each note shall be subject to the same terms as described in the preceding paragraph except that the per share liquidation preference will equal the conversion price.

•

The conversion price for all Lenders, regardless of purchase date, for this Next Equity Financing is the lesser of 80% of the per share issue price of the equity securities sold in this financing event or a calculated per share value based on a defined valuation cap and fully-diluted capital.

•

If the Next Equity Financing conversion, Corporate Transaction conversion, SPAC conversion or repayment of the outstanding principal and unpaid accrued interest has not occurred on or before the maturity date (December 31, 2025), the principal and unpaid accrued interest of each 2023 Convertible Note shall, at the written election of the Requisite Noteholders (which must include certain noteholder), pursuant to mutually agreed-upon terms, be automatically converted (the “Maturity Conversion”) into a class of equity shares subject to mutual agreement between the Lenders and the Company.

•

If the Next Equity Financing conversion, Corporate Transaction conversion or repayment of the outstanding principal and unpaid accrued interest has not occurred prior to a SPAC transaction, the principal and unpaid accrued interest of each 2023 Convertible Note, with the exception of notes issued to a Final Closing Lender, shall automatically convert (the “SPAC Conversion”) into a number of common shares equal to the quotient obtained by dividing the outstanding principal and unpaid accrued interest on each 2023 Convertible Note by the applicable conversion price. The conversion price in this SPAC Conversion is the lesser of 80% of the SPAC price per share or a calculated per share value based on a defined valuation cap and fully-diluted capital immediately prior to the SPAC transaction.

•

In the event of a Corporate Transaction (any “Liquidation Event” as defined in the existing Certificate of Incorporation), the 2023 Convertible Notes shall be repaid as follows at the closing of the Corporate Transaction:

•

For any Lender who purchased a 2023 Convertible Note on or before July 3, 2023, in respect of a Corporate Transaction that occurs on or before July 3, 2024, an amount equal to the then accrued but unpaid interest plus three (3) times the then outstanding principal.

•

For any Lender who purchased a 2023 Convertible Note on or before July 3, 2023, in respect of a Corporate Transaction that occurs after July 3, 2024, an amount equal to the then accrued but unpaid interest plus five (5) times the then outstanding principal.

•

For any Lender who purchased a 2023 Convertible Note after July 3, 2023, in respect of any such Corporate Transaction, an amount equal to the then accrued but unpaid interest plus one and a half (1.5) times the then outstanding principal.

Investors in the 2023 Convertible Notes also received warrants to purchase the same type of equity shares into which the 2023 Convertible Notes are converted (see Notes 8 and 13).

Investors in these secured convertible notes also received warrants to purchase equity shares of the Company.

The Company elected to measure the 2023 Convertible Notes in their entirety at fair value with changes in fair value reported in a single line in the consolidated statements of operations. The 2023 Convertible Notes were fair valued using a scenario-based method, considering five future event scenarios: Next Equity Financing, Maturity Conversion, SPAC Conversion, Corporate Transaction, and Default. The conversion payout was calculated for each assumed event scenario, with probabilities estimated by management. The payout of the 2023 Convertible Notes under each event scenario were discounted back to the valuation date using a discount rate aligned with the company’s credit rating and the weighted average present value of each scenario used for the fair value of the 2023 Convertible Notes.

For

the years ended December

2024

and

2023

, the Company recognized a change in fair value of approximately $

8.7

million and $

6.9

million, respectively. Upfront costs and fees related to items for which the fair value option is elected must be recognized immediately. As such issuance costs (warrants) and fees associated with the convertible notes were recognized in current earnings.

One investor who purchased a 2023 Convertible Note also received an RSU grant for a total of

6,000,000

RSUs (see Note

13)

which originally vested in full on the

one-year

anniversary of the grant date with such vesting subject to full acceleration upon the consummation of an IPO, SPAC Transaction, Direct Listing or Sale Event, as defined. The RSUs were valued on the date of issuance equal to the fair value of common stock approximating $

2.6

million and accounted for as Debt Financing Charge on the

2023

Convertible Note. On December

Basis Of Presentation And Summary Of Significant Accounting Policies

Note 2. Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”) and reflect all adjustments, including normal recurring adjustments, which, in the opinion of management, are necessary to present fairly the financial position, results of operations, and cash flows for the periods presented in accordance with U.S. GAAP. The consolidated financial statements include the financial statements of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated upon consolidation.

Use of Estimates

The preparation of the consolidated financial statements in accordance with U.S. GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods presented. Such estimates and assumptions include, but are not limited to, those related to revenue recognition, the valuation of accounts receivable, the net realizable value of inventory, the useful lives of long-lived assets, the incremental borrowing rate used in calculating operating lease right of use assets, the accounting for income taxes, the estimates used to evaluate the

recoverability of long-lived assets, amortization method and periods for capitalized software, and the estimated fair value of convertible notes, warrant liabilities, and common stock, and

stock-based

compensation expense. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, and adjusts such estimates and assumptions when facts and circumstances dictate. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates.

Cash and Cash Equivalents

The

Company considers all highly liquid investments with an original maturity of

days or less to be cash equivalents in the consolidated financial statements. The Company’s cash equivalents are primarily comprised of U.S. Government treasury securities, mutual funds, and money market funds. The Company has cash deposits in a financial institution that, at times, may be in excess of Federal Deposit Insurance Corporation (“FDIC”) insurance limits. The Company has not experienced losses in such accounts and periodically evaluates the creditworthiness of its financial institutions.

of December

2024

and

2023

, the Company had cash and cash equivalents balances in excess of domestic and international insurance limits of approximately $

49.3

million and $

2.2

million, respectively.

of December

2024

, the Company held $

30.6

million in U.S. Government treasury securities, $

9.2

million in a U.S. Government money market fund, and $

5.1

million in mutual funds (see Note

. As of December

2023

, the Company had

cash equivalents.

Restricted Cash

Restricted cash represents cash balances held as security deposits related to international payment services. As of December

2024

, restricted cash of $

0.3

million was included within other assets on the consolidated balance sheets. As of December

2023

, the Company had

restricted cash.

Accounts Receivable, Net

Accounts receivable, net is recorded at the invoiced amount and does not accrue interest. The allowance for credit losses is the Company’s estimate of the amount of probable credit losses in the Company’s existing accounts receivable. The Company determines that allowance based upon a review of each receivable and all known factors that could affect collectability. These factors include but are not limited to a customer’s past payment performance, customer financial condition, general economic or industry conditions and disputes regarding the invoiced amount or the product or service rendered. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. The allowance for credit losses was $

0.4

million as of December 31, 2024 and 2023, respectively. As of December 31, 2024 and 2023, the Company’s accounts receivable included

zero

and approximately $

0.5

million, respectively, of unbilled accounts receivable (See Note 13).

Inventories

Inventories consist of raw materials, work in process inventories, and finished goods. Inventories are stated at the lower of cost or net realizable value, with cost being determined on a

first-in,

first-out

basis. Net realizable value is the estimated selling price in the ordinary course of business less the estimated costs of completion and the estimated costs necessary to make the sale. Adjustments to reduce the cost of inventory to its net realizable

value are made, if required, for estimated excess, obsolescence, or impaired balances. At the point of loss recognition, a new lower cost basis for that inventory is established and subsequent changes in facts and circumstances do not result in the restoration or increase in the newly established cost basis. Any write-downs of inventories are reflected as part of cost of revenue in the consolidated statement of operations.

Property and Equipment, Net

Property and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the

straight-line

method over the following estimated useful lives:



Computer equipment		3-5 years
Software		3 years
Furniture and fixtures		5 years
Office equipment		5 years
Vehicles		8 years
Leasehold improvements		Shorter of the related lease term or useful life

The Company capitalizes additions and improvements while repair and maintenance costs are expensed to operations as incurred. Upon retirement or sale of a fixed asset, the cost of the asset and related accumulated depreciation are removed from the accounts and the net amount, less proceeds from disposal, is credited or charged as a gain or loss in the consolidated statements of operations.

Leases

The Company determines if an arrangement is or contains a lease based on the unique facts and circumstances present at the inception of the arrangement and if such a lease is classified as a financing lease or operating lease. Operating lease

right-of-use

(“ROU”) assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. Operating lease ROU assets also include any initial direct costs and prepayments less lease incentives. Lease terms include periods under options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. The Company generally uses the base,

non-cancelable,

lease term when determining the lease assets and liabilities. As of December 31, 2024 and 2023, the Company had

finance leases.

Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise such options. As the Company’s leases do not provide an implicit rate, the Company uses its collateralized incremental borrowing rate based on the information available at the lease commencement date, including any reasonably certain renewal lease term, in determining the present value of lease payments. Lease expense for these operating leases is recognized on a straight-line basis over the lease term and is reflected in the consolidated statements of operations in selling, general and administrative expenses. Payments under lease arrangements are primarily fixed, however, most lease agreements also contain variable payments. Variable lease payments are expensed as incurred and not included in the operating lease ROU assets and lease liabilities. These variable amounts primarily include payments for taxes, parking and common area maintenance.

The Company has made an accounting policy election not to recognize ROU assets and lease obligations for its short-term leases, which are defined as leases with an initial term of twelve months or less. However, the Company will recognize these lease payments in the consolidated statements of operations on a straight-line basis over the lease term and variable lease payments in the period in which the obligation is incurred. Lease payments for

month-to-month

leases are recognized as incurred.

Software Development Costs

Software development costs for software to be sold, leased, or marketed are accounted for in accordance with Accounting Standards Codification (“ASC”) 985-20,

Software — Costs of Software to be Sold, Leased or Marketed

. Under ASC 985-20, software development costs incurred in creating software solutions are expensed until technological feasibility has been established and costs are determined to be recoverable. Thereafter, all software development costs incurred through the software’s general release date to customers are capitalized and subsequently recorded at the lower of amortized cost or net realizable value. To date, the establishment of technological feasibility of the Company’s software solutions has occurred shortly before the software’s general release date to customers. Additionally, amortization is calculated on a software

feature-by-feature

basis and the estimated economic life of a feature is one year. To date, the impact of capitalizing qualifying software development costs has been immaterial.

Deferred Offering Costs

Deferred offering costs, which consist of direct incremental legal, consulting and banking fees primarily relating to the Company’s merger with BurTech (see Note 1), whereby the Company will become a public company, are capitalized and will be offset against proceeds upon the consummation of the offering within stockholders’ deficit. In the event an anticipated offering is terminated, deferred offering costs will be expensed. As of December 31, 2024 and 2023 there were $

11.1

million and $

1.5

million, respectively, capitalized deferred offering costs included in prepaid expenses and other current assets on the consolidated balance sheets.

Impairment of

Long-Lived

Assets

Whenever events or changes in circumstances indicate that the carrying amount of

long-lived

assets may not be recoverable, the Company estimates the expected undiscounted future cash flows from the use of those assets and their eventual disposition (without any allocated debt financing charges). If the sum of the expected undiscounted future cash flows is less than the carrying amount of those assets, the Company recognizes an impairment loss based on the excess of the carrying amount over the fair value of the assets. For the years ended December 31, 2024 and 2023, the Company did

t recognize any impairment expense related to its long-lived assets.

Embedded Derivative Evaluation

The Company evaluates the terms of its debt instruments to determine if any identified embedded features, including embedded conversion options or redemption features, are required to be bifurcated and accounted for separately as a derivative financial instrument. In circumstances where a host instrument contains more than one embedded derivative instrument, including a conversion option, that is required to be bifurcated, the bifurcated derivative instruments would be accounted for as a single, compound derivative instrument. Any identified and bifurcated embedded derivatives are initially recorded at fair value and are revalued at each reporting date with changes in the fair value reported as

non-operating

income or expense.

Convertible Notes

The Company accounts for its convertible notes, some of which contain predominantly fixed rate conversion features, whereby the outstanding principal and accrued interest may be converted by the holder into a variable number of shares of preferred stock at a fixed discount to the market price of the common stock at the time of conversion under ASU

2020-06

Debt—Debt with Conversion and Other Options (Subtopic

470-20),

Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic

815-40)

and

Accounting for Convertible Instruments

and Contracts in an Entity’s Own Equity

(ASU

2020-06).

The Company has elected to account for its convertible notes at fair value at each period end pursuant to ASC 825,

Financial Instruments

wherein changes in the fair value are recorded as change in fair value of convertible notes in the consolidated statements of operations.

Warrant Liabilities

The Company has issued freestanding warrants in connection with certain of its convertible debt agreements and preferred stock issuances which have been recorded as long-term liabilities in the consolidated balance sheets at their estimated fair value. At initial recognition, the warrants were recorded at their estimated fair value calculated using the Black-Scholes-Merton (“Black-Scholes”) option pricing model (see Note 8). The liability associated with these warrants is subject to remeasurement at each balance sheet date, with changes in fair value recorded as change in the fair value of warrant liabilities in the consolidated statements of operations. The warrants will continue to be remeasured until the earlier of the expiration or exercise of the warrants. The warrants are recorded at fair value each reporting period using the Black-Scholes option pricing model.

Redeemable Convertible Preferred Stock

The Company’s redeemable convertible preferred stock has been classified outside of stockholders’ deficit, as mezzanine equity, due to the redemption option of the preferred stock shareholders (see Note 10). The Company records redeemable convertible preferred stock at fair value on the dates of issuance, net of issuance costs. The Company has adjusted the carrying values of the redeemable convertible preferred stock, subsequent to the initial issuance date, to the redemption value of such shares because it is probable that the convertible preferred stock will become redeemable.

Revenue Recognition

The Company derives revenue from product sales, license and development arrangements, joint marketing arrangements and cloud services. The Company recognizes revenue under ASC Topic 606,

Revenue from Contracts with Customers

(ASC 606), in which it determines revenue recognition through the following steps:

Step 1: Identify the contract with the customer.

The Company considers the terms and conditions of the engagement in identifying the contracts. The Company determines a contract with a customer to exist when the contract is approved, each party’s rights regarding the services to be transferred can be identified, the payment terms for the services can be identified, it has been determined the customer has the ability and intent to pay, and the contract has commercial substance. At contract inception, the Company will evaluate whether two or more contracts should be combined and accounted for as a single contract and whether the combined or single contract includes more than one performance obligation. The Company applies judgment in determining the customer’s ability and intent to pay, which is based on a variety of factors, including the customer’s historical payment experience or, in the case of a new customer, credit, and financial information pertaining to the customer.

Step 2: Identify the performance obligations in the contract.

Performance obligations promised in a contract are identified based on the services that will be transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the service either on its own or together with other resources that are readily available from third parties or from the Company and are distinct in the context of the contract.

Step 3: Determine the transaction price.

The transaction price is determined based on the consideration to which the Company expects to be entitled in exchange for transferring services to the customer. Variable consideration is included in the transaction price if, in the Company’s judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. None of the Company’s contracts contain a significant financing component.

Step 4: Allocate the transaction price to the performance obligations in the contract.

Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on each performance obligation’s relative standalone selling price (“SSP”).

Step 5: Recognize revenue when the company satisfies a performance obligation.

Revenue is recognized at the time the related performance obligation is satisfied by transferring the control of the promised service to a customer. Revenue in respect of services, including nonrecurring engineering services or marketing services, is recognized over the contractual terms during which the Company provides services over period of time. Hardware revenue is recognized at a point in time when the product is shipped. The Company generates all its revenue from contracts with customers.

Revenue from hardware sales is recognized upon transfer of control of products to customers in an amount that reflects the consideration the Company expects to receive in exchange for the hardware. The Company offers unspecified upgrades and support on certain products, however, the related revenue has historically not been material.

The Company’s license and development arrangements entail revenue from the licensing of its intellectual property (“IP”) and also include nonrecurring engineering development services to configure the Company’s IP and hardware to a customer’s needs. For each contract, the Company considers the promise to deliver a license that grants the customer the right to use the IP, as well as any professional services provided under the contract, as distinct performance obligations. The Company recognizes licensing revenue from such arrangements over the term of the arrangements and recognizes professional services over time as the services are provided. The Company measures progress to completion based on actual costs incurred to date as a percentage of the estimated total cost required to complete the project.

The

timing of the Company’s revenue recognition may differ from the timing of payment by its customers. An unbilled receivable is recorded when revenue is recognized prior to invoicing and the Company has an unconditional right to payment. Alternatively, when payment precedes the provision of the related services, the Company records deferred revenue until the performance obligations are satisfied.


	2024			2023

Balance at January 1	$	1,100		$	1,830
Addition of deferred revenue		—			3,113
Recognition of revenue		(1,100	)		(3,843	)

Balance at December 31	$	—		$	1,100

The Company defers incremental costs of obtaining a customer contract and amortizes the deferred costs over the period that the related revenue is recognized. The Company had no material incremental costs to obtain customer contracts in any period presented.

The Company has elected to account for shipping and handling fees as fulfillment activities and not separate performance obligations. Accordingly, these fees are reflected in revenue and the related fulfillment costs are accrued as cost of revenue as the related fulfillment costs incurred.

The Company offers a standard assurance-type warranty to customers for hardware sales.

Research and Development

Costs related to the Company’s research and development (“R&D”) activities are expensed as incurred. R&D expense consists primarily of personnel costs for the Company’s R&D activities. R&D expense also includes costs associated with the design and development of the Company’s AI edge computing hardware and software.

Advertising Costs

Advertising costs are expensed as incurred and are included in selling, general and administrative expenses in the consolidated statements of operations. Advertising costs were immaterial for the years ended December 31, 2024 and 2023, respectively.

Income Taxes

The Company is subject to income taxes in the U.S. and various foreign jurisdictions. The Company uses the

asset-and-liability

method for income taxes. Under this method, deferred tax assets and liabilities are determined based on differences between the financial statement carrying amounts and tax bases of assets and liabilities and operating loss and tax credit carryforwards and are measured using the enacted tax rates that are expected to be in effect when the differences reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established on a

jurisdiction-by-jurisdiction

basis when necessary to reduce deferred tax assets to an amount that, in the opinion of management, is more likely than not to be realized.

The Company is subject to tax audits in various jurisdictions. The Company regularly assesses the likely outcomes of such audits in order to determine the appropriateness of liabilities for uncertain tax benefits. The Company accounts for uncertain tax positions based on an evaluation as to whether it is more likely than not that a tax position will be sustained upon audit, including resolution of any related appeals or litigation processes. This evaluation is based on all available evidence and assumes that the appropriate tax authorities have full knowledge of all relevant information concerning the tax position. The tax benefit recognized is based on the largest amount that is greater than 50% likely of being realized upon ultimate settlement. The Company includes interest expense and penalties related to its uncertain tax positions in income tax expense.

Stock-Based Compensation

The Company recognizes the cost of employee, non-employee consultants and

non-employee

directors’ services received in exchange for awards of stock options based on the fair value of those awards at the date of grant over the requisite service period. The fair value of stock options granted is determined using the Black-

Scholes option-pricing model using various inputs, including Company estimates of expected stock price volatility, term, risk-free rate and future dividends. The Company has elected the simplified method to determine the expected term of the option grants.

The Company also grants RSUs to employees and

non-employee

consultants, which vest upon the satisfaction of both a service-based condition and a liquidity event condition, as defined. The fair value of restricted stock units is determined based on the Company’s estimated fair value of common stock at the date of grant. As of December 31, 2024 and 2023, the Company has

t recorded any stock-based compensation expense associated with the RSUs as a liquidity event has not occurred. If a liquidity event occurs in the future, the Company will record cumulative stock-based compensation using the accelerated attribution method for those RSUs for which the service condition has been satisfied prior to the liquidity event, and the Company will record the remaining unrecognized stock-based compensation over the remainder of the requisite service period.

Forfeitures are recognized as they occur.

Fair Value Measurements

The Company determines fair value measurements used in its consolidated financial statements based upon the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy distinguishes between (i) market participant assumptions developed based on market data obtained from independent sources (observable inputs), and (ii) an entity’s own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs). ASC 820,

Fair Value Measurements,

requires fair value measurements be classified and disclosed in one of the following pricing categories:

Level

- This level consists of unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity can access at the measurement date.

Level

2 -

This level consists of observable inputs other than the quoted prices included within Level 1, such as quoted prices for similar assets or liabilities in markets that are not active or for which all significant inputs are observable or can be corroborated by observable market data, either directly or indirectly, for substantially the full term of the asset or liability.

Level 3

- This level consists of unobservable inputs for the asset or liability to the extent that observable inputs are not available, thereby allowing for situations in which there is little or no market data for the asset or liability at the measurement date. This requires the reporting entity to develop its own assumptions that market participants would use in pricing the asset or liability. The carrying amounts of cash, accounts receivable, prepaid expenses and other current assets, accounts payable, accrued loss on purchase commitments and accrued expenses and other liabilities approximate fair value because of their short-term maturities.

Foreign Currency

The Company’s reporting and functional currency is the United Stated dollar (“USD”). The local currencies of its foreign subsidiaries are the Indian rupee, British pound, or Philippine peso, however, the functional currency of its foreign subsidiaries is also the USD. Monetary assets and liabilities denominated in currencies other than USD are remeasured into USD at current exchange rates and nonmonetary assets and liabilities are measured at historical exchange rates. Revenues, cost of revenues, and operating expenses are remeasured at the average exchange rates in effect during each reporting period. The resulting transaction gains or losses are

recognized in other income (expense), net, in the consolidated statements of operations. During the year ended December 31, 2024, foreign currency transaction losses of $

0.2

million was included in other income (expense), net in the consolidated statements of operations. During the year ended December 31, 2023, foreign currency transaction gain was immaterial.

Concentration of Credit Risk

The Company’s cash and cash equivalents are primarily on deposit at high-credit quality financial institutions or invested in U.S. Government money market funds. The Company’s cash accounts in a financial institution may at times exceed the Federal Depository Insurance coverage of $

250,000

. Investments in money markets are not insured or guaranteed by the FDIC or any other government agency.

The Company is exposed to credit risk in the event of nonpayment by customers up to the amounts recorded on the consolidated balance sheets. The Company manages its accounts receivable credit risk through ongoing credit evaluation of its customers’ financial conditions.

As of December 31, 2024, one customer accounted for approximately

% of the Company’s accounts receivable. As of December 31, 2023, one customer, a related party, accounted for approximately

% of the Company’s accounts receivable (see Note 13).

Historically, a relatively small number of customers have accounted for a significant portion of the Company’s revenue. For the year ended December 31, 2024, two customers, both related parties, accounted for approximately

% and

% of the Company’s revenue. For the year ended December 31, 2023, one customer, a related party, accounted for nearly

100

% of the Company’s revenue (see Note 13).

Net Loss Per Share

Basic and diluted net loss per share attributable to common stockholders is presented in conformity with the two-class method required for participating securities. The two-class method determines net income (loss) per share for each class of common and participating securities according to dividends declared or accumulated and participation rights in undistributed earnings. The two-class method requires income (loss) available to common stockholders for the period to be allocated between common and participating securities based upon their respective rights to shares in undistributed earnings as if all income (loss) for the period had been distributed. The Company’s redeemable convertible preferred stock contractually entitles the holders of such stock to participate in dividends but does not contractually require the holders of such stock to participate in losses of the Company. Accordingly, in periods in which the Company reports a net loss attributable to common stockholders, such losses are not allocated to such participating securities.

Basic net loss per share is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of common stock outstanding during the period, without consideration of potentially dilutive securities. Diluted net loss per share is computed by dividing the net loss attributable to common stockholders by the weighted-average number of common stock and potentially dilutive securities outstanding for the period. For purposes of this calculation, redeemable convertible preference stock, stock options and warrants have been excluded from the calculation of diluted net loss per share attributable to common stockholders as their effect is anti-dilutive for all periods presented.

Segment Reporting

in deciding how to allocate resources and assessing performance. The Company’s Chief Executive Officer is the chief operating decision maker (“CODM”), who reviews financial information presented on a consolidated basis for the purposes of making operating decisions, allocating resources and evaluating financial performance.

Emerging Growth Company Status

The Company is expected to be an emerging growth company, as defined in Section 2(a) of the Securities Act of 1933, as amended, (the “Securities Act”), as modified by the Jumpstart Our Business Startups Act of 2012 (“JOBS Act”). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act, until such time as those standards apply to private companies. The Company has elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that the Company (i) is no longer an emerging growth company or (ii) affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, these consolidated financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates.

Summary of Significant Accounting Policies

Note 2. Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

These condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”) for interim financial information and with the instructions to Form

10-Q

and Rule

10-01

of Regulation

S-X.

Accordingly, they do not include all the information and footnotes required by U.S. GAAP for complete financial statements. The accompanying unaudited interim condensed consolidated financial statements reflect all adjustments which are, in the opinion of management, necessary for a fair statement of the results for the interim periods presented. The results of operations of any interim period are not necessarily indicative of the results of operations to be expected for the full fiscal year. The unaudited interim condensed consolidated financial statements should be read in conjunction with Blaize, Inc.’s consolidated financial statements and accompanying footnotes included in the Company’s Form

8-K/A

filed with the U.S. Securities and Exchange Commission (“SEC”) on April 15, 2025, which provides a more complete discussion of the Company’s accounting policies and certain other information.

Use of Estimates

The preparation of the condensed consolidated financial statements in accordance with U.S. GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods presented. Such estimates and assumptions include, but are not limited to, those related to revenue recognition, the allowance for credit losses, the net realizable value of inventory, the useful lives of long-lived assets, the incremental borrowing rate used in calculating operating lease right of use assets, the accounting for income taxes, the estimates used to evaluate the recoverability of long-lived assets, amortization method and periods for capitalized software, and the estimated fair values of convertible notes, warrant liabilities, earnout share liabilities, and common stock, and stock-based compensation expense. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, and adjusts such estimates and assumptions when facts and circumstances dictate. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates.

Cash and Cash Equivalents

The Company considers all highly liquid investments with an original maturity of 90 days or less to be cash equivalents in the condensed consolidated financial statements. The Company’s cash equivalents are primarily comprised of U.S. Government treasury securities, mutual funds, and money market funds. The Company has cash deposits in a financial institution that, at times, may be in excess of Federal Deposit Insurance Corporation insurance limits. The Company has not experienced losses in such accounts and periodically evaluates the creditworthiness of its financial institutions.

As of March 31, 2025 and December 31, 2024, the Company had cash and cash equivalents balances, inclusive of funds held in escrow, in excess of domestic and international insurance limits of approximately $71.9 million and $49.3 million, respectively.

As of March 31, 2025, the Company held $30.9 million in U.S. Government treasury securities, $5.3 million in U.S. Government money market funds, and $5.1 million in mutual funds, while as of December 31, 2024, the Company held $30.6 million in U.S. Government treasury securities, $9.2 million in U.S. Government money market funds, and $5.1 million in mutual funds (see Note 5).

Restricted Cash

Restricted cash represents cash balances held as security deposits related to international payment services. As of March 31, 2025 and December 31, 2024, restricted cash of $0.3 million was included within other assets on the condensed consolidated balance sheets.

Funds Held in Escrow

As of March 31, 2025, the Company held $33.4 million of cash in an interest-earning escrow account pursuant to certain

non-redemption

agreements entered into with several unaffiliated stockholders of the Company, whereby amounts are required to be held in a separate account at the Closing of the Merger and held until such time that certain

non-redeemed

shares are either sold in the open market and/or put to the Company. The funds in escrow approximate $11.57 per

non-redeemed

share (see Note 3).

Accounts Receivable, Net

Inventories

Inventories consist of raw materials, work in process inventories, and finished goods. Inventories are stated at the lower of cost or net realizable value, with cost being determined on a

first-in,

first-out

basis. Net realizable value is the estimated selling price in the ordinary course of business less the estimated costs of completion and

the estimated costs necessary to make the sale.

Adjustments

to reduce the cost of inventory to its net realizable value are made, if required, for estimated excess, obsolescence, or impaired balances. At the point of loss recognition, a new lower cost basis for that inventory is established and subsequent changes in facts and circumstances do not result in the restoration or increase in the newly established cost basis. Any write-downs of inventories are reflected as part of cost of revenue in the condensed consolidated statements of operations.

Deferred Offering Costs

Deferred offering costs consist of direct incremental legal, consulting and banking fees primarily relating to the Merger (see Note 3). The capitalized costs were fully expensed upon the consummation of the Merger within transaction costs on the condensed consolidated statement of operations during the three months ended March 31, 2025. As of December 31, 2024, there were $11.1 million of capitalized deferred offering costs included in prepaid expenses and other current assets on the condensed consolidated balance sheets.

Impairment of Long-Lived Assets

Whenever events or changes in circumstances indicate that the carrying amount of long-lived assets may not be recoverable, the Company estimates the expected undiscounted future cash flows from the use of those assets and their eventual disposition (without any allocated debt financing charges). If the sum of the expected undiscounted future cash flows is less than the carrying amount of those assets, the Company recognizes an impairment loss based on the excess of the carrying amount over the fair value of the assets. For the three months ended March 31, 2025 and 2024, the Company did not recognize any impairment expense related to its long-lived assets.

Legacy Blaize Convertible Notes

Prior to the consummation of the Merger, the Company accounted for its convertible notes, some of which contained predominantly fixed rate conversion features under ASU

Debt—Debt with Conversion and Other Options (Subtopic

470-20),

Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic

and

Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity

. The Company elected to account for its convertible notes at fair value at each period end pursuant to ASC 825,

Financial Instruments

wherein changes in the fair value were recorded as change in fair value of convertible notes in the condensed consolidated statements of operations. The convertible notes were remeasured just prior to the date of the Merger and upon the closing of the Merger, the convertible notes were fully converted into shares of common stock (see Note 3 and Note 5).

Legacy Blaize Warrant Liabilities

Prior to the consummation of the Merger, the Company had issued freestanding warrants in connection with certain of its convertible debt agreements and preferred stock issuances which were recorded as current liabilities on the condensed consolidated balance sheets at their estimated fair value. At initial recognition, the warrants were recorded at their estimated fair value calculated using the Black-Scholes-Merton (“Black-Scholes”) option pricing model (see Note 9). The liability associated with these warrants were subject to fair value remeasurement at each balance sheet date, with changes in fair value recorded as change in the fair value of warrant liabilities on the condensed consolidated statements of operations. The warrants were remeasured just prior to the date of the Merger and, upon the consummation of the Merger, the warrant liabilities were fully converted into shares of common stock.

Earnout Shares

In connection with the Merger, Legacy Blaize shareholders and outstanding equity award holders (including stock options and RSUs) are entitled to receive up to 15,000,000 shares of the Company’s Class A common stock (the “Earnout Shares”) (see Note 3). Earnout Shares issued to eligible Legacy Blaize equity holders (including holders of stock options and restricted stock units (“RSUs”)) are considered a compensatory award and are accounted for under ASC 718,

Share-Based Compensation

. Further these awards have been determined to be equity classified and accordingly will not be remeasured at each reporting date.

The Earnout Shares issued to Burkhan and all other equity holders not within the scope of ASC 718 in connection with consummation of the Merger, were evaluated by management under ASC 480,

Distinguishing Liabilities from Equity

(see Note 3). The Company determined that the Earnout Shares are freestanding and not liability classified under ASC 480. Subsequently, management evaluated whether the Earnout Shares represented a derivative instrument pursuant to ASC 815,

Derivatives and Hedging

. The Company concluded that the Earnout Shares under the arrangement resulted in liability classification pursuant to ASC

815-40.

The liability for such Earnout Shares will be remeasured at each reporting date with changes in the fair value recorded to earnings on the condensed consolidated statements of operations

Legacy Blaize Redeemable Convertible Preferred Stock

Prior to the consummation of the Merger, the Company had (i) Series Seed Shadow Preferred Stock, (ii) Series A Shadow Preferred Stock, (iii) Shadow B Shadow Preferred Stock, (iv) Series C Shadow Preferred Stock, (v) Series D Shadow Preferred Stock, (vi) Series D Exchange Shadow Preferred Stock, (vii) Series

D-1

Shadow Preferred Stock, (viii) Series

D-1

Exchange Shadow Preferred Stock, and (ix) Series

D-2

Shadow Preferred Stock, all outstanding. The Company’s redeemable convertible preferred stock had been classified outside of stockholders’ equity (deficit), as mezzanine equity, due to the redemption option of the preferred stock shareholders. The Company recorded redeemable convertible preferred stock at fair value on the dates of issuance, net of issuance costs. The Company adjusted the carrying values of the redeemable convertible preferred stock, subsequent to the initial issuance date, to the redemption value of such shares because it was probable that the convertible preferred stock would become redeemable.

Upon the consummation of the Merger, all shares of redeemable convertible preferred stock outstanding were converted into shares of common stock (see Note 3). All shares of redeemable convertible preferred stock which were converted into shares of common stock were retroactively adjusted using the exchange ratio and reclassified into permanent equity as a result of the Merger.

Common Stock Subject to Possible Redemption

The Company accounts for common stock subject to possible redemption in accordance with the guidance in ASC Topic 480

Distinguishing Liabilities from Equity

. Certain common stock is held in escrow pursuant to

Non-Redemption

Agreements and feature certain redemption rights that are considered to be outside of the Company’s control and within the control of the holders (see Note 3). Accordingly, as of March 31, 2025, 2,854,242 shares of common stock are subject to possible redemption, and have been presented at redemption value as temporary equity, outside of the stockholders’ equity (deficit) section of the condensed consolidated balance sheet.

The Company recognizes changes in redemption value as they occur by adjusting the carrying value of common stock subject to possible redemption to equal the redemption value as of the end of each reporting period. Changes in the carrying amount of redeemable common stock are affected by charges against additional

paid-in

capital and accumulated deficit.

Warrants

The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in ASC 480 and ASC 815, Derivatives and Hedging. The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company’s own common stock, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance, as well as each subsequent reporting period while the warrants are outstanding.

For issued or modified warrants that meet all of the criteria for equity classification, the warrants are required to be recorded as a component of additional

paid-in

capital at the time of issuance. For issued or modified warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded at their initial fair value on the date of issuance, and each balance sheet date thereafter. The Company analyzed the warrants issued in BurTech’s Initial Public Offering (“Public Warrants”),warrants included in the Private Placement Units (the “Private Warrants”) and warrants issued to advisor for services (the “Common Stock Warrants”) and determined they are considered to be freestanding instruments and do not exhibit any of the characteristics in ASC 480 and therefore are not classified as liabilities under ASC 480. As of March 31, 2025, the Company’s outstanding public warrants and private warrants met all the requirements for equity classification under ASC 815 and therefore were classified as equity. As of December 31, 2024, Legacy Blaize warrants were classified as liabilities, as described above.

Revenue Recognition

The Company derives revenue from product sales, license and development arrangements, joint marketing arrangements and cloud services. The Company recognizes revenue under ASC 606,

Revenue from Contracts with Customers,

in which it determines revenue recognition through the following steps:

Step 1: Identify the contract with the customer.

has been determined the customer has the ability and intent to pay, and the contract has commercial substance. At contract inception, the Company will evaluate whether two or more contracts should be combined and accounted for as a single contract and whether the combined or single contract includes more than one performance obligation. The Company applies judgment in determining the customer’s ability and intent to pay, which is based on a variety of factors, including the customer’s historical payment experience or, in the case of a new customer, credit, and financial information pertaining to the customer.

Step 2: Identify the performance obligations in the contract.

Step 3: Determine the transaction price.

Step 4: Allocate the transaction price to the performance obligations in the contract.

Step 5: Recognize revenue when the company satisfies a performance obligation.

The timing of the Company’s revenue recognition may differ from the timing of payment by its customers. An unbilled receivable is recorded when revenue is recognized prior to invoicing and the Company has an unconditional right to payment. Alternatively, when payment precedes the provision of the related services, the Company records deferred revenue until the performance obligations are satisfied. The following table is a rollforward of contract liabilities, which are included in accrued expenses and other current liabilities and other liabilities:


	Contract Liabilities
(Amounts in thousands)	2025		2024
Balance as of January 1	$	—	$	1,100
Additions to deferred revenue		—		1,728
Deferred revenue recognized		—		(183	)

Balance as of March 31	$	—	$	2,645

The Company offers a standard assurance-type warranty to customers for hardware sales.

Income Taxes

The Company is subject to income taxes in the U.S. and various foreign jurisdictions. The Company uses the

asset-and-liability

jurisdiction-by-jurisdiction

basis when necessary to reduce deferred tax assets to an amount that, in the opinion of management, is more likely than not to be realized.

The Company is subject to tax audits in various jurisdictions. The Company regularly assess the likely outcomes of such audits in order to determine the appropriateness of liabilities for uncertain tax benefits. The Company accounts for uncertain tax positions based on an evaluation as to whether it is more likely than not that a tax position will be sustained upon audit, including resolution of any related appeals or litigation processes. This evaluation is based on all available evidence and assumes that the appropriate tax authorities have full knowledge of all relevant information concerning the tax position. The tax benefit recognized is based on the largest amount that is greater than 50% likely of being realized upon ultimate settlement. The Company includes interest expense and penalties related to its uncertain tax positions in the provision for income taxes.

Stock-Based Compensation

The Company recognizes the cost of employee,

non-employee

consultants and

non-employee

The Company also grants RSUs to employees and

non-employee

consultants, which vest upon the satisfaction of both a service-based condition and a liquidity event condition, as defined. The fair value of RSUs is determined based on the Company’s estimated fair value of common stock at the date of grant. Due to the Merger that occurred during the three months ended March 31, 2025, the Company recorded cumulative stock-based compensation using the accelerated attribution method for those RSUs for which the service condition has been satisfied prior to the Merger, and will record the remaining unrecognized stock-based compensation over the remainder of the requisite service period (see Note 13). The Company did not record any stock-based compensation expense associated with the RSUs during the three months ended March 31, 2024, as a liquidity event had not occurred during that period.

Forfeitures are recognized as they occur.

Fair Value Measurements

The Company determines fair value measurements used in its condensed consolidated financial statements based upon the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy distinguishes between (i) market participant assumptions developed based on market data obtained from independent sources (observable inputs), and (ii) an entity’s own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs). ASC 820, Fair Value Measurements, requires fair value measurements be classified and disclosed in one of the following pricing categories:


Level 1:		This level consists of unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity can access at the measurement date.

Level 2:		This level consists of observable inputs other than the quoted prices included within Level 1, such as quoted prices for similar assets or liabilities in markets that are not active or for which all significant inputs are observable or can be corroborated by observable market data, either directly or indirectly, for substantially the full term of the asset or liability.

Level 3:		This level consists of unobservable inputs for the asset or liability to the extent that observable inputs are not available, thereby allowing for situations in which there is little or no market data for the asset or liability at the measurement date. This requires the reporting entity to develop its own assumptions that market participants would use in pricing the asset or liability.

The carrying amounts of cash, funds held in escrow, accounts receivable, prepaid expenses and other current assets, accounts payable, accrued loss on purchase commitments, working capital loans, and accrued expenses and other liabilities approximate their fair values due to their short-term maturities.

Foreign Currency

average exchange rates in effect during each reporting period. The resulting transaction gains or losses are recognized in other income (expense), net, in the condensed consolidated statements of operations. During the three months ended March 31, 2025 and 2024, foreign currency transaction gains and losses were immaterial.

Concentration of Credit Risk

The Company’s cash and cash equivalents are primarily on deposit at high-credit quality financial institutions or invested in U.S. Government treasury securities, mutual funds, and money market funds. The Company’s cash accounts in a financial institution may at times exceed the Federal Depository Insurance coverage of $250,000. Investments in money markets are not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

As of March 31, 2025, one customer accounted for approximately 95% of the Company’s accounts receivable. As of December 31, 2024, one customer accounted for approximately 98% of the Company’s accounts receivable.

Historically, a relatively small number of customers have accounted for a significant portion of the Company’s revenue. For the three months ended March 31, 2025, one customer accounted for approximately 95% of the Company’s revenue. For the three months ended March 31, 2024, two customers, both related parties, accounted for approximately 61% and 39% of the Company’s revenue (see Note 15).

Net Loss Per Share

Basic and diluted net loss per share attributable to common stockholders is presented in conformity with the

two-class

method required for participating securities. The

two-class

method determines net income (loss) per share for each class of common and participating securities according to dividends declared or accumulated and participation rights in undistributed earnings. The two class method requires income (loss) available to common stockholders for the period to be allocated between common and participating securities based upon their respective rights to shares in undistributed earnings as if all income (loss) for the period had been distributed.

Basic net loss per share is calculated by dividing the net loss attributable to common stockholders by the weighted average number of common stock outstanding during the period, without consideration of potentially dilutive securities. Diluted net loss per share is computed by dividing the net loss attributable to common stockholders by the weighted average number of common stock and potentially dilutive securities outstanding for the period. For purposes of this calculation, stock options and warrants have been excluded from the calculation of diluted net loss per share attributable to common stockholders as their effect is anti-dilutive for all periods presented.

As the Merger has been accounted for as a reverse recapitalization, net loss per share was also retroactively adjusted for periods ended prior to the Merger.

Segment Reporting

The Company operates in one reporting segment. Operating segments are defined as components of an enterprise about which separate financial information is evaluated regularly by the chief operating decision maker (“CODM”) in deciding how to allocate resources and assessing performance. The Company’s Chief Executive Officer is the CODM, who reviews financial information presented on a consolidated basis for the purposes of making operating decisions, allocating resources and evaluating financial performance.

Commitments And Contingencies	Mar. 31, 2025	Dec. 31, 2024
Loss Contingencies [Line Items]
Commitments and Contingencies	Note 14. Commitments and Contingencies Purchase Commitments As of March 31, 2025, the Company had outstanding purchase orders and contractual obligations totaling $0.3 million to procure inventory. The majority of the Company’s outstanding inventory purchase orders and preauthorized commitments to procure strategic components based on expected demand are placed with its primary third-party contract manufacturer and a semiconductor supplier. The Company has an obligation to purchase inventories that have been purchased by the contract manufacturer when components have not been consumed within a period defined in the terms of our agreement. During the three months ended March 31, 2025 and 2024, the Company purchased inventories of $0.1 million and $3.3 million, respectively, due to this obligation. While the Company expects such purchased components to be used in future production of its finished goods, these components are considered in its reserve estimate for excess and obsolete inventory. Furthermore, the Company accrues for losses on commitments for the future purchase on non-cancelable and non-returnable components from this contract manufacturer at the time that circumstances, such as changes in expected demand, indicate that the value of the components may not be recoverable, the loss is probable and management has the ability to reasonably estimate the amount of the loss. As of March 31, 2025 and December 31, 2024, the liability balance of our accrued losses on purchase commitments equaled $0.6 million on the condensed consolidated balance sheets. Legal Proceedings From time to time, the Company may become involved in claims or other legal matters arising in the ordinary course of business. The Company records accruals for outstanding legal proceedings when it is probable a liability will be incurred, and the amount of loss can be reasonably estimated. On September 9, 2024, BurTech entered into an Advisory Services Engagement Letter with Jefferies to serve as its exclusive capital markets advisor in connection with the contemplated Merger involving Legacy Blaize (the “Jefferies Engagement Letter”), pursuant to which Jefferies would be eligible for a fee of $4,500,000 contingent upon the closing of the Merger and for reimbursement of expenses up to $500,000. On April 7, 2025, Jefferies commenced a lawsuit against the Company in the Supreme Court of the State of New York, County of New York, seeking summary judgment in lieu of complaint. The lawsuit alleges that pursuant to the Jefferies Engagement Letter, Jefferies was entitled to receive a fee of $4,500,000 conditional on the Closing of the Merger, with the option for the Company to defer up to $1,000,000 of this fee for up to 12 months post-closing, and $500,000 in reimbursable expenses. Jefferies alleges that as of March 31, 2025, no fees have been paid to Jefferies under the Jefferies Engagement Letter. Jefferies seeks $3,500,000 for its fees, as well as $500,000 in expense reimbursement, as well as pre-and post-judgment interest and attorneys’ fees and legal costs incurred in connection with the lawsuit. The Company has retained counsel and intends to vigorously defend the litigation. Although the outcome of this matter cannot be predicted with certainty, based on the existing facts and circumstances the Company has recorded estimated liabilities of $4,950,000 on the condensed consolidated balance sheets as of March 31, 2025, of which $3,950,000 is included in accounts payable and $1,000,000 is included in accrued expenses and other current liabilities. These estimated liabilities reflect management’s assessment of the Company’s potential exposure from the Jefferies Engagement Letter based on its contracted fees. The resolution of this matter could differ materially from the amount currently recorded. The Company continues to evaluate the matter as it progresses and will adjust the estimated liabilities if and when additional information becomes available that indicates a different outcome is probable and reasonably estimable. Advisor Agreements In October through December of 2024, the Company entered into various advisor agreements related to business development and strategy, and for new revenue contracts, in new geographical markets. Compensation for services, pending approval by the Company’s Board of Directors, is in the form of restricted stock units following the filing of a registration statement subsequent to the Merger consummation to register such shares, and subject to the advisors continued service on the applicable grant date. In December 2024, the Company entered into an agreement for capital market services which included advisory services and a finder’s fee, for which payment was due upon the close of the Merger (see Note 3). Under the terms of the agreement, at the Company’s discretion, the advisory fee of $0.8 million is to be paid in the form of (i) cash and (ii) cash or a combination of cash and shares of common stock of common stock at a price of $10.00 per share at various dates in 2025. The finder’s fee, equal to a specified percentage of the trust value of our shares held by investors introduced by the advisor, is to be paid fifty percent in cash and fifty percent in shares of common stock at a price of $10.00 per share, concurrent with the close of the Merger. The Company recognized $0.6 million associated with the contract as deferred offering costs and accrued liabilities for the year ended December 31, 2024. On the earlier of the date that is six months from the date of the Merger and the date that a Registration Statement filed with the SEC registering the resale of the closing shares is declared effective (the “Reset Date”), if the five day volume weighted average price of common stock for the five trading days immediately preceding the Reset Date (such price, the “Reset Price”) is less than $10.00 per share (subject to a $1.00 per share floor), within two days we shall issue an additional number of common shares equal to the number obtained by dividing (i) the product of the number of shares held as of the Reset Date and $10.00 by (ii) the Reset Price, less the number of sharing shares held, provided that the additional shares shall not exceed 300,000.	Note 12. Commitments and Contingencies Purchase Commitments As of December 31 , 2024 , the Company had outstanding purchase orders and contractual obligations totaling $ 0.2 million to procure inventory. The majority of the Company’s outstanding inventory purchase orders and preauthorized commitments to procure strategic components based on the Company’s expected demand are placed with the Company’s primary third party contract manufacturer and a semiconductor supplier. The Company has an obligation to purchase inventories that have been purchased by the contract manufacturer when components have not been consumed within a period defined in the terms of the Company’s agreement. During the years ended December 31 , 2024 and 2023 , the Company purchased inventories of $ 4.3 million and $ 4.4 million, respectively, due to this obligation. While the Company expects such purchased components to be used in future production of Company finished goods, these components are considered in the Company’s reserve estimate for excess and obsolete inventory. Furthermore, the Company accrues for losses on commitments for the future purchase on non-cancelable and non-returnable components from this contract manufacturer at the time that circumstances, such as changes in expected demand, indicate that the value of the components many not be recoverable, the loss is probable and management has the ability to reasonably estimate the amount of the loss. As of December 31 , 2024 and 2023 , the liability balance of the Company’s accrued losses on accrued purchase commitments equaled $ 0.6 million and $ 3.6 million, respectively, on the consolidated balance sheets. Legal Proceedings From time to time, the Company may become involved in claims or other legal matters arising in the ordinary course of business. The Company records accruals for outstanding legal proceedings when it is probable a liability will be incurred, and the amount of loss can be reasonably estimated. The Company does not believe that there are any pending legal proceedings or other loss contingencies that will, either individually or in the aggregate, have a material adverse effect on the Company’s consolidated financial statements. Merger Agreement The December 22 , 2023 Merger Agreement as amended (see Note 1) , provided that as soon as reasonably practicable following the date of the Merger Agreement, Burkhan and/or its affiliates and/or nominees shall purchase from the Company: (i) convertible promissory notes under the Company’s 2023 NPA (see Note 7) and (ii) the Burkhan Pre-funded Warrant (see Note 8) for aggregate gross proceeds to the Company of $ 25.0 million. In addition, 16,300,000 shares of New Blaize common stock may be issued as earnout shares for a period from the closing of the business combination until the five -year anniversary thereof, in accordance with the schedule set forth in the Merger Agreement. The earnout shares are to be issued to Burkhan and eligible shareholders of the Company contingent, in each case, on the closing stock price of the New Blaize common stock exceeding specific thresholds. On April 22 , 2024 , the Company, BurTech LP LLC, and BurTech entered into a Backstop Subscription Agreement. Pursuant to the Backstop Subscription Agreement, in the event that the amount of cash in BurTech’s trust account following redemptions and before payment of expenses is less than $ 30,000,000 , BurTech LP LLC shall purchase, prior to or substantially concurrently with the closing of the Merger, a number of shares of Class A common stock of BurTech equal to the difference between $ 30,000,000 minus the Trust Amount divided by $ 10.00 per share. The April Amendment also amended various definitions and covenants to reflect the funding commitment of the BurTech’s Sponsor pursuant to the Backstop Subscription Agreement. O n April 22 , 2024 , BurTech LP LLC and BurTech entered into a letter agreement. Under this agreement, conditioned upon the occurrence of the closing of the Merger, BurTech LP LLC agreed to forfeit 2,000,000 BurTech Shares to be effective immediately prior to the closing. The Lock-Up Agreement attached to the Merger Agreement was also amended on April 22, 2024 to include certain consent requirements to the transfer of the Burkhan Prefunded Warrant Stock and grant the Company Board of Directors the discretion to determine whether certain persons will be subject to the lock-up requirements. On October 24, 2024, BurTech, Merger Sub, the Company and Burkhan entered into an Amendment No. 2 to Agreement and Plan of Merger (the “Second Amendment to Merger Agreement”). The Second Amendment to Merger Agreement amended the original merger agreement to revise the New Blaize Board designees to nine members, including four individuals to be designated by the Company and five independent directors, designated by the Company after consultation, in good faith, with BurTech regarding the determination of the independent directors, with the chairman designated until a new chairperson is appointed by the New Blaize Board. On November 21, 2024, BurTech, Merger Sub, Blaize and Burkhan entered into an Amendment No. 3 to Agreement and Plan of Merger (the “Third Amendment to Merger Agreement”). The Third Amendment to Merger Agreement amended the original merger agreement to (i) revise the New Blaize Board designees to be comprised of seven members, including two individuals to be designated by Blaize and five independent directors, designated by Blaize after consultation, in good faith, with BurTech regarding the determination of the independent directors, with Lane M. Bess to be designated as the Chairman until a new chairperson is appointed by the New Blaize Board, (ii) remove the agreement between BurTech, Sponsor and Burkhan to enter into the Stockholders’ Agreement at the closing of the Business Combination and to remove such Form of Stockholders’ Agreement as an exhibit to the original merger agreement and (iii) replace the proposed Third Amended and Restated Certificate of Incorporation with a new Form of Third Amended and Restated Certificate of Incorporation to reflect that the New Blaize Board will not be a classified board. Pursuant to the terms and subject to the conditions set forth in the Merger Agreement, on January 13, 2025, the transaction was consummated (see Note 1). Other On September 19, 2024, the Company entered into an engagement letter with KeyBanc Capital Markets Inc. (“KBCM”) to serve as its (i) exclusive strategic advisor in connection with the Business Combination, (ii) sole and exclusive placement agent for private placement services and (iii) sole and exclusive financial advisor in connection with any potential sale transactions. Pursuant to the engagement, the Company agreed to pay KBCM (i) a strategic advisory fee of $ 1,000,000 upon the Closing of the Business Combination and (ii) a placement fee based on a percentage of the gross proceeds from any private placements or, in the event no private placement is completed by KBCM has used reasonable best efforts to secure such a private placement, a fee of $ 500,000 promptly (but not later than two business days ) following the close of the Business Combination. Additionally, a sale transaction fee will be paid, calculated as the greater of $ 3,000,000 or 1 % of the transaction value. On October 24, 2024, contingent upon the close of the proposed merger on or before December 31, 2024 and continued employment or services to the Company on the applicable grant date, the Company’s Board of Directors approved the issuance of 6,936,285 restricted stock units under the New Blaize equity plan.

Description of Business

Note 1. Description of Business

Blaize,

Inc. (collectively “Blaize” or “the Company”) was originally incorporated on

February 16, 2010

, as a Delaware corporation under the name of ThinCI, Inc. and commenced operations at that time. On October 17, 2019, the Company’s Board of Directors adopted a Restated Certificate of Incorporation, which changed the Company’s name to Blaize, Inc. The Company is headquartered in El Dorado Hills, California, and consists of four separate legal entities: Blaize, Inc. (United States of America), Blaize New Computing Technologies India Private Limited (India), Blaize Technologies Philippines, Inc. (Philippines) and Blaize U.K. LTD (England). Blaize designs and develops

low-power,

high-efficiency, programmable artificial intelligence (“AI”) edge computing hardware and software. Blaize leads a new generation of computing, which unleashes the potential of AI in order to enable significant increases in the value that technology delivers to improve the way people work and live. The Company offers transformative edge computing solutions for AI data collection and processing, with a focus on smart vision and other AI applications for the automotive, retail, security and industrial markets.

In November

2023, the Company entered into a Memorandum of Understanding with a United Arab Emirates (“UAE”) based third-party investment entity to establish a cooperative framework for both entities to discuss and explore commercial and technical collaboration in the UAE. The collaboration is intended to be operationalized through a newly created entity, Blaize Artificial Intelligence Middle East, LLC, in which the Company has a

% ownership. As of December 31, 2024, there has not been an operating agreement executed between the Company and the holder of the

% interest that would make the Company the primary beneficiary of this new legal entity. The newly established entity has incurred insignificant expenses since its incorporation.

Merger Agreement

On January 13, 2025 (the “Closing Date”), BurTech Acquisition Corp. (“BurTech”) and its subsidiary, BurTech Merger Sub, Inc, (“Merger Sub”), and Blaize, Inc. (“Legacy Blaize”) consummated the transaction contemplated by the Agreement and Plan of Merger (the “Merger Agreement”), dated as of December 22, 2023 (as amended on April 22, 2024, October 24, 2024 and November 21, 2024), with BurTech Merger Sub, Inc., Blaize, Inc., and for the limited purposes set forth therein, Burkhan Capital LLC, a Delaware limited liability company and affiliate of BurTech (“Burkhan”). Under the Merger Agreement, Merger Sub was merged with and into the Company, with the Company surviving the merger as a wholly owned subsidiary of BurTech (the “Business Combination” and, together with the other transactions contemplated by the Merger Agreement, the “Merger”).

Concurrent with the Merger, BurTech was renamed Blaize Holdings, Inc. (“Blaize Holdings”). Beginning on January 14, 2025, Blaize Holdings’ common stock and warrants trade on NASDAQ under the ticker symbols “BZAI” and “BZAIW”, respectively.

Prior to the Merger, BurTech LP LLC was the sponsor of BurTech (the “Sponsor”) and with the close of the Merger either BurTech LP LLC or its affiliated entities, has remained a significant shareholder in Blaize Holdings.

The equity exchange and other financing-related matters associated with the Merger are summarized as follows:

Legacy Blaize Convertible Promissory Notes and Equity

Immediately before the closing of the Merger, the convertible notes outstanding plus all accrued and unpaid interest, each of the issued and outstanding shares of redeemable convertible preferred stock, and all outstanding

warrants, net exercised, were automatically converted into shares of the Company’s common stock. Upon the consummation of the Merger,

each share of the Company’s common stock issued and outstanding were canceled and converted into the right to receive shares of Blaize Holdings Class A common stock and each share of Merger Sub Capital Stock was converted into one share of Blaize Holdings Class A common stock

, par value $

0.0001

Further upon the Closing Date, (i) each Company option granted was converted into (a) the right to receive a number of Blaize Holdings Earnout Shares and (b) a Blaize Holdings option, upon substantially the same terms and conditions as in effect with respect to the corresponding Company option and (ii) each Company RSU granted was converted into (a) the right to receive a number of Blaize Holdings Earnout Shares and (b) a Blaize Holdings restricted stock unit (“RSU”), upon substantially the same terms and conditions as in effect with respect to the corresponding Blaize RSU.

Earnout Arrangement with holders of Legacy Blaize Common Stock and outstanding equity awards

Concurrent

with the Closing Date, holders of the Company common stock and outstanding equity awards (including stock options and RSU holders) agreed to the right to receive up to an aggregate amount of

15,000,000

shares of Blaize Holdings Class A Common

Stock (the “Earnout Shares”) during specified periods following the Merger (the “Earnout Period”) that will be issued if the following targets or triggering events are achieved:

•

3,750,000 Earnout Shares will be issued upon the occurrence of the first date during the Earnout Period on which the closing stock price of Blaize Holdings Class A Common Stock is greater than or equal to $12.50 per share for twenty (20) trading days within a thirty (30) consecutive trading day period;

•

3,750,000 Earnout Shares will be issued upon the occurrence of the first date during the Earnout Period on which the closing stock price of Blaize Holdings Class A Common Stock is greater than or equal to $15.00 per share for twenty (20) trading days within a thirty (30) consecutive trading day period;

•

3,750,000 Earnout Shares will be issued upon the occurrence of the first date during the Earnout Period on which the closing stock price of Blaize Holdings Class A Common Stock is greater than or equal to $17.50 per share for twenty (20) trading days within a thirty (30) consecutive trading day period;

•

3,750,000 Earnout Shares will be issued upon the occurrence of the first date during the Earnout Period on which the closing stock price of Blaize Holdings Class A Common Stock is greater than or equal to $20.00 per share for twenty (20) trading days within a thirty (30) consecutive trading day period.

Company employees entitled to receive Earnout Shares with respect to Blaize Holdings options and RSUs, must provide service through the date the target is achieved and if an employee departs, the Earnout Shares are reallocated to the remaining pool of recipients who received the right to the Earnout Shares on the Closing Date.

Additionally,

Burkhan agreed to the right to receive up to an aggregate amount of 2,600,000 shares of Blaize Holdings Class A Common Stock following the occurrence of each triggering event stated above (the “Burkhan Earnout Shares”). The Burkhan Earnout Shares will vest in four equal tranches of 325,000 shares plus 325,000 Blaize Holdings Class A Common Stock multiplied by the cash ratio (the “Proportionate Shares Number”). The “Cash Ratio” is the ratio equal to (x) Available Acquiror Cash, divided by (y) the Minimum Cash Amount (both of such terms as defined in the Merger Agreements).

Other Arrangements entered into at time of Merger or assumed upon Merger:

Blaize Warrants

On January 13, 2025, upon closing of the Merger, 28,750,000 of public warrants and 898,250 of private warrants of BurTech that were outstanding immediately before to the Merger became warrants of Blaize Holdings.

PIPE Shares

From December 31, 2024 through January 13, 2025, BurTech and certain subscribers (each, a “Subscriber” and collectively, the “Subscribers”) entered into subscription agreements (each, a “PIPE Subscription Agreement” and collectively, the “PIPE Subscription Agreements”) under which BurTech agreed to issue and sell to the Subscribers, immediately before the Closing Date, collectively, 1,540,300 shares of Class A Stock (the “PIPE Shares”) at a price per share equal to $10.00 (the “PIPE Investment”). Such shares that were outstanding immediately prior to the Merger became shares of Blaize Holdings. See Note 17.

Sponsor Note

On January 13, 2025, in connection with the consummation of the Business Combination and as contemplated by the Merger Agreement, the Sponsor issued a secured promissory note and pledge agreement (the “Sponsor Note”) to BurTech (the “Holder”) in the principal amount of $8,753,744 bearing an interest rate of 7% with annual compounding, compounded on December 31 each year the Sponsor Note remains outstanding for the remaining principal amount of the Sponsor Note as at the maturity date, until such remaining principal amount is paid. Pursuant to the Sponsor Note, the Sponsor granted a first priority security interest in, and pledges, 2,000,000 shares of Class A Stock and all additions, accessions and substitutions to the Holder to secure the satisfaction by the Sponsor of all its obligations to the Holder under the Sponsor Note. The Sponsor Note was issued in connection with the consummation of the Business Combination in satisfaction of the acquiror transaction expenses (as defined in the Merger Agreement) that were due to third-party service providers on or immediately following the Merger. As consideration for entry into the Sponsor Note, BurTech issued 750,000 shares of Class A Stock (“Sponsor Note Shares”) to the Sponsor in accordance with the terms of the Sponsor Note (the “Sponsor Note Issuance” and together with the PIPE Investment, the “Private Placements”). The shares of Class A Stock issued in consideration for the Sponsor Note were offered in a private placement under the Securities Act, pursuant to the Sponsor Note. Upon the Closing Date, such shares and note remained outstanding instruments of Blaize Holdings. See Note 17.

Non-Redemption

Agreement

On and around December 31, 2024, BurTech entered into an agreement

(“Non-Redemption

Agreement”) with one or more unaffiliated stockholders of BurTech (each, an “Investor”) who agreed not to redeem (or validly rescind any redemption requests on) their shares of BurTech Class A common stock, par value $0.0001 per share of BurTech

(“Non-Redeemed

Shares”). In exchange for the foregoing commitments not to redeem the

Non-Redeemed

Shares, Blaize and BurTech LP LLC have agreed to guarantee that each Investor receives a return of $1.50 per

Non-Redeemed

Share whether an Investor (i) sells the

Non-Redeemed

Shares in the open market or (ii) exercises its option to require Blaize Holdings to repurchase the

Non-Redeemed

Shares in accordance with the

Non-Redemption

Agreement.

Registration Rights Agreement

Pursuant to the Merger Agreement, at the Closing Date, Blaize Holdings, the Sponsor, certain significant securityholders of the Company and certain of their respective affiliates entered into an Amended and Restated Registration Rights Agreement (the “Registration Rights Agreement”), in which Blaize Holdings agreed to register for resale, pursuant to Rule 415 under the Securities Act of 1933, as amended (the “Securities Act”), certain shares of Blaize Holdings Class A Common Stock and other equity securities of Blaize Holdings that are held by the parties thereto from time to time on the terms and subject to the conditions set forth therein.

Lock-up

Agreement

At the Closing Date, Blaize Holdings entered into

lock-up

agreements (the

“Lock-up

Agreements”) with (i) certain of Blaize Holdings’ directors and officers, (ii) certain stockholders of Blaize Holdings and (iii) Burkhan, in each case, restricting the transfer of Blaize Holdings Class A Common Stock and any shares of Blaize Holdings Class A Common Stock issuable upon the exercise or settlement, as applicable, of Blaize Holdings Options or Blaize Holdings RSUs held by it immediately after the effective time of the Merger. The restrictions under the

Lock-up

Agreements began at the Closing Date and end on the date that is 180 days after the Closing Date, or upon the earlier of (x) the last reported sale price of Blaize Holdings common stock reaching $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any

30-trading

day period commencing at least 150 days after the Closing Date and (y) the liquidation of Blaize Holdings.

Accounting for the Business Combination

The merger between the Company and BurTech will be accounted for as a reverse recapitalization, with BurTech being treated as the “acquired” company for financial reporting purposes. Blaize has been determined to be the accounting acquirer of BurTech based on the following facts and circumstances:

•

Blaize is the larger entity in terms of substantive operations and employee base and its operations represent the ongoing operations of the combined entity.

•

Blaize’s existing shareholders have the greatest voting interest in the combined entity.

•

Blaize’s existing shareholders have the ability to control decisions regarding election and removal of the combined entity’s board of directors.

•

Blaize’s senior management is the senior management of the combined entity.

•

The combined company name is named Blaize Holdings, Inc., i.e. the combined entity has assumed Blaize’s name.

For accounting purposes, the reverse recapitalization is the equivalent of the Company issuing stock for the net assets of BurTech, accompanied by a recapitalization. The net assets of BurTech will be stated at historical cost, with no goodwill or other intangible assets being recorded. Operations prior to the reverse recapitalization will be those of the Company. The consolidated financial statements as of and for the periods prior to December 31, 2024 have not been adjusted to reflect the Merger.

Liquidity and Going Concern

The Company’s consolidated financial statements have been prepared on a going concern basis, which assumes that it will be able to meet its obligations and continue its operations during the twelve months following

the issuance of these consolidated financial statements. These consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classifications of liabilities that may result should the Company be unable to continue as a going concern.

Since inception

of the Company and through December 31, 2024, the Company has funded its operations primarily with cash flows from contributions from founders or other investors and other financing activities. The Company has incurred recurring losses and

negative cash flows since its inception, including a net loss of $

61.2

million and $

87.6

million for the years ended December

2024

and

2023

, respectively. As of December

2024

, the Company had cash and cash equivalents of approximately $

50.2

million, a net working capital deficit of $

114.5

million, and an accumulated deficit of $

429.3

million.

The Company’s ability to continue to meet its obligations, to achieve its business objectives and continue as a going concern is dependent upon several factors, including the Company’s revenue growth rate, the timing and extent of spending to support further sales and marketing and research and development efforts. In order to finance these opportunities, the Company will need to raise additional financing. While there can be no assurances, the Company intends to raise such capital through issuances of additional debt financing and public or private equity offerings or other means. If additional financing is required from outside sources, the Company may not be able to raise it on terms acceptable to the Company or at all. If the Company is unable to raise additional capital when desired, the Company’s business, results of operations and financial condition would be materially and adversely affected.

As a result of the above, in connection with the Company’s assessment of going concern considerations in accordance with Financial Accounting Standard Board’s (“FASB”) Accounting Standards Update (“ASU”)

2014-15,

Disclosures of Uncertainties about an Entity’s Ability to Continue as a Going Concern

, management has determined that the Company’s liquidity condition raises substantial doubt about the Company’s ability to continue as a going concern through a year from the date these consolidated financial statements are available to be issued.

Level 1:		This level consists of unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity can access at the measurement date.

Level 2:		This level consists of observable inputs other than the quoted prices included within Level 1, such as quoted prices for similar assets or liabilities in markets that are not active or for which all significant inputs are observable or can be corroborated by observable market data, either directly or indirectly, for substantially the full term of the asset or liability.

Level 3:		This level consists of unobservable inputs for the asset or liability to the extent that observable inputs are not available, thereby allowing for situations in which there is little or no market data for the asset or liability at the measurement date. This requires the reporting entity to develop its own assumptions that market participants would use in pricing the asset or liability.

Stock-Based Compensation:

In November 2011, and as amended in December 2018 and August 2021, the Company adopted the 2011 Stock Plan (the “2011 Amended Plan”). Under the 2011 Amended Plan, incentive stock options (“ISOs”) may be granted to employees at exercise prices not lower than the fair value of the stock at the date of grant as determined by the Board, or the committee appointed by the Board to administer the 2011

Amended Plan

. For ISOs granted to a person who, at the time of the grant, owns stock representing more than

% of the total combined voting power of all classes of the Company’s stock, the per share exercise price must be no less than

110

% of the fair value on the date of the grant as determined by the Board.

The Company recognizes compensation expense for service-based options on a straight-line basis over the requisite service period of all employees or

non-employees,

which is the award’s vesting term, generally over four years. The Company accounts for forfeitures when they occur.

The Company also grants RSUs, which vest upon the satisfaction of both the service-based condition and a liquidity event condition. The liquidity event condition for the RSUs is satisfied upon the occurrence of a qualifying event, defined specifically in the equity documents, and generally refer to the earlier of a specified period of time subsequent to an initial public offering or an acquisition, in all cases prior to the expiration date of the award. Additionally, for all terminated RSU grants, all RSUs which have satisfied a portion or all of the service-based condition of the termination date remain with the stockholder and do not return to the pool of shares available for issuance until the earlier of the satisfaction of the liquidity event (at which time those RSUs vest) or the expiration date of the award. The RSUs expire as defined by the individual RSU grant, generally the

earlier of (i) the first anniversary or second anniversary of terminated service, for 2023 and prior grants, respectively, for any reason and (ii) expire date defined as the fifth anniversary of the date of grant.

The fair value of RSUs is determined based on the Company’s estimated fair value of common stock at the date of grant, as determined by the Board of Directors.

As of December

2024

, there were service-based stock options outstanding to purchase a total of

36,363,184

shares of common stock under the Plan and

4,655,274

unvested RSUs. As of December

2024

2,226,705

shares of common stock were available for issuance for either stock option or RSU grants under the

2011

Amended Plan.

The aggregate

intrinsic value of service-based options exercised during the years ended December

2024

and

2023

was $

17,000

and

zero

, respectively. The intrinsic value is the difference between the estimated fair value of the Company’s common stock at the date of exercise and the exercise price for

in-the-money

stock options.

The weighted-average

grant-date fair value of options granted during the years ended December

2024

and

2023

was $

0.88

per share and $

0.25

per share, respectively. The total grant date fair value of stock options that vested during the years ended December

2024

and

2023

was $

2.8

million and $

0.8

million, respectively.

As of December

2024

there were approximately $

18.2

million of total unrecognized compensation cost related to unvested stock options granted, which is expected to be recognized over the weighted-average period of

2.4

years.

The Company recorded stock-based compensation expense for stock options and the

2024

cancellation of

135,400

RSUs during the years ended December

2024

and

2023

, as follows (in thousands):


	2024		2023
Research and development	$	1,106	$	372
Selling, general and administrative		2,741		2,111
Total	$	3,847	$	2,483

The Company uses the Black-Scholes option-pricing model to determine the grant-date fair value of stock options. The determination of the fair value of stock options on the grant date is affected by the estimated underlying common stock price, as well as assumptions regarding a number of complex and subjective variables. These variables include expected stock price volatility over the term of the awards, actual and projected employee stock option exercise behaviors, risk-free interest rates, and expected dividends. The grant date fair value of the Company’s stock options granted in the years ended December 31, 2024 and 2023 was estimated using the Black-Scholes model with the range of assumptions stated below:


	2024		2023
Risk-free interest rate		3.99% - 4.43%		4.44% - 4.46%
Expected life, in years		5.00 - 6.22		5.00 - 6.01
Expected volatility		56.92% - 57.51%		56.74% - 57.56%
Dividend yield		— %		— %
Weighted average fair value of common stock	$	0.88	$	0.25

The risk-free interest rate is based on the U.S. Treasury constant maturities on the date of the grant for the time period equal to the expected term of the options granted. Expected volatility was calculated for the given term on the basis of the average volatilities of a peer group of representative public companies having considered characteristics such as industry, stage of life cycle, size, financial leverage and comparable programs and participant pools. The Company determined the use of historical volatility for similar entities represents a more accurate calculation of option fair value. Expected life is calculated using the simplified method (based on the

mid-point

between the vesting date and the end of the contractual term of the option). The Company has no history or experience of paying cash dividends on its common stock and thus, has assumed a

zero-dividend

rate. The assumptions used to calculate the fair value of options granted are evaluated and revised for new awards, as necessary, to reflect market conditions and experience.

On the Closing Date, all outstanding options were converted into new instruments in accordance with the terms of the Merger (see Note 1).

Restricted-Stock Units:

A summary of the Company’s RSU activity issued under the 2011 Amended Plan, inclusive of the

6,000,000 RSUs issued to an investor (see Notes 7 and 13), for the years ended December 31, 2024 and 2023 is as follows:


	Awards			Weighted- average grant date fair value (per share)
Nonvested as of January 1, 2023		137,909		$	15.28
Issued		10,929,820		$	0.60
Exercised		(6,000,000	)	$	0.44
Forfeited		(150,900	)	$	1.98

Nonvested as of December 31, 2023		4,916,829		$	1.18
Forfeited		(254,555	)	$	0.88
Expired		(7,000	)	$	0.82

Nonvested as of December 31, 2024		4,655,274		$	1.19

The RSUs

have both a service-based condition and a liquidity event condition. The liquidity event condition is only satisfied on the consummation of the liquidity event, such as an IPO, which is currently not determinable or probable. As the satisfaction of the liquidity event condition for all RSUs is neither determinable nor probable as of December

2024

stock-based compensation expense was recognized for the periods presented. As of December

2024

, there was $

6.3

million of total unrecognized compensation expense related to outstanding RSU equity awards. Since the RSUs only vest on the consummation of a liquidity event which is currently not determinable or probable, the Company is unable to determine the weighted-average period over which the unrecognized cost will be recognized.

The

6,000,000

RSUs issued as part of the

2023

Convertible Note financing were fair valued on the date of grant and recognized as debt financing charge at date of transaction (see Notes

and

13)

. Effective December

2023

, as a condition of executing the Merger Agreement, the Company accelerated the vesting associated with the

6,000,000

RSUs. Upon acceleration, the RSUs were immediately exchanged and

6,000,000

shares of common stock issued. The modification of vesting terms resulted in the recognition of $

1.7

million in stock-based compensation expense during the year ended December

2023

On the Closing Date, all outstanding RSUs were converted into new instruments in accordance with the terms of the Merger (see Note 1).
