Cautionary Note Regarding Forward-Looking Statements
This Report contains “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act. Statements that do not relate strictly to historical or current facts are forward-looking and usually identified by the use of words such as “anticipate,” “believe,” “could,” “estimate,” “expect,” “forecast,” “future,” “intend,” “may,” “opportunity,” “plan,” “project,” “seek,” “should,” “strategy,” “will,” “will likely result,” “would” and other similar words and expressions, but the absence of these words does not mean that a statement is not forward-looking. Forward-looking statements may relate to the development of the Company’s technology, the anticipated demand for the Company’s technology and the markets in which the Company operates, the timing of the deployment of plant deliveries, and the Company’s business strategies, capital requirements, potential growth opportunities and expectations for future performance (financial or otherwise). Forward-looking statements are based on current expectations, estimates, projections, targets, opinions and/or beliefs of the Company, and such statements involve known and unknown risks, uncertainties and other factors.

The risks and uncertainties that could cause those actual results to differ materially from those expressed or implied by these forward-looking statements include: (i) risks relating to the uncertainty of the projected financial information with respect to the Company and risks related to the Company’s ability to meet its projections; (ii) the ability to recognize the anticipated benefits of the Business Combination, which may be affected by, among other things, competition, the ability of the Company to grow and manage growth profitably, and the ability of the Company to retain its management and key employees; (iii) the Company’s ability to utilize its net operating loss and tax credit carryforwards effectively; (iv) the capital-intensive nature of the Company’s business model, which will likely require the Company to raise additional capital in the future; (v) barriers the Company may face in its attempts to deploy and commercialize its technology; (vi) the complexity of the machinery the Company relies on for its operations and development; (vii) potential changes and/or delays in site selection and construction that result from regulatory, logistical, and financing challenges; (viii) the Company’s ability to establish and maintain supply relationships; (ix) risks related to the Company’s arrangements with third parties for the development, commercialization and deployment of technology associated with the Company’s technology; (x) risks related to the Company’s other strategic investors and partners; (xi) the Company’s ability to successfully commercialize its operations; (xii) the availability and cost of raw materials; (xiii) the ability of the Company’s supply base to scale to meet the Company’s anticipated growth; (xiv) the Company's ability to expand internationally; (xv) the Company’s ability to update the design, construction, and operations of its technology; (xvi) the impact of potential delays in discovering manufacturing and construction issues; (xvii) the possibility of damage to the Company’s Texas facilities as a result of natural disasters; (xviii) the ability of commercial plants using the Company’s technology to efficiently provide net power output; (xix) the Company’s ability to obtain and retain licenses; (xx) the Company’s ability to establish an initial commercial scale plant; (xxi) the Company’s ability to license to large customers; (xxii) the Company’s ability to accurately estimate future commercial demand; (xxiii) the Company’s ability to adapt to the rapidly evolving and competitive natural and renewable power industry; (xxiv) the Company’s ability to comply with all applicable laws and regulations; (xxv) the impact of public perception of fossil fuel-derived energy on the Company’s business; (xxvi) any political or other disruptions in gas producing nations; (xxvii) the Company’s ability to protect its intellectual property and the intellectual property it licenses; (xxviii) risks relating to data privacy and cybersecurity, including the potential for cyberattacks or security incidents that could disrupt our or our service providers’ operations; (xxix) potential litigation that may be instituted against the Company; and (xxx) other risks and uncertainties indicated in Part I, Item 1A of the Annual Report and other documents subsequently filed with the SEC by the Company .

Should one or more of these risks or uncertainties materialize, or should any of the assumptions made by our management prove incorrect, actual results may vary in material respects from those projected in the forward-looking statements contained in this Report. Accordingly, you should not place undue reliance on these forward-looking statements in deciding whether to invest in our securities.

Forward-looking statements speak only as of the date they are made. Except to the extent required by applicable law or regulation, we undertake no obligation to update the forward-looking statements contained herein to reflect events or circumstances after the date of this Report or to reflect the occurrence of unanticipated events. The Company gives no assurance that it will achieve its expectations.

NET Power Inc.
Notes to Condensed Consolidated Financial Statements (Unaudited)
NOTE 1 — Nature of Business and Basis of Presentation
Nature of Business
NET Power Inc. (“Net Power” or the “Company”) is a clean energy technology company that has developed a proprietary process for producing electricity using a predominantly carbon dioxide working fluid that involves the capture and reuse, sale and sequestration of carbon dioxide (the “Net Power Cycle”). The Net Power Cycle is the subject of U.S. and foreign patents, as well as additional applications and provisional applications on file with the United States Patent and Trademark Office and international patent authorities.
Basis of Presentation
The accompanying unaudited condensed consolidated financial statements included in this Quarterly Report on Form 10-Q have been prepared in conformity with accounting principles generally accepted in the United States of America (“US GAAP”) for interim financial information; however, certain information or footnote disclosures normally included in complete financial statements prepared in accordance with US GAAP may have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). In management’s opinion, these unaudited condensed consolidated financial statements have been prepared on the same basis as the annual financial statements for the year ended December 31, 2024 and include all adjustments, which consist of only normal and recurring adjustments, necessary for fair statement. Certain prior period financial information has been reclassified to conform to current period presentation.
The results reported in these unaudited condensed consolidated financial statements are not necessarily indicative of the results to be expected for the entire year. These unaudited condensed consolidated financial statements should be read in conjunction with the annual financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on March 10, 2025 (the “2024 Annual Report”).

NOTE 2 — Significant Accounting Policies
The Company’s significant accounting policies used to prepare these condensed consolidated financial statements, unless otherwise noted below, are consistent with those used for the fiscal year ended December 31, 2024. Accordingly, refer to Note 2 to the consolidated financial statements in the 2024 Annual Report for the Company’s significant accounting policies.
Use of Estimates
The preparation of financial statements in conformity with US GAAP requires management to make certain estimates, judgments and assumptions. The estimates, judgments and assumptions made by the Company when accounting for items and matters such as, but not limited to, depreciation, amortization, asset valuations and share-based compensation were based on information available at the time they were made. These estimates, judgments, and assumptions can affect the reported amounts of assets and liabilities as of the date of the condensed consolidated financial statements, as well as amounts reported on the condensed consolidated statements of operations and comprehensive loss during the periods presented. Actual results could differ from those estimates.
10
Segment Reporting
In accordance with ASC Topic 280, Segment Reporting ( “ ASC 280 ” ), the Company has determined that it has one operating segment and one reportable segment, which includes all of the Company’s consolidated accounts. The Company’s chief operating decision maker (“CODM”) is its Chief Executive Officer. The CODM focuses on consolidated Operating income (loss), with a focus on research and development and general and administrative expenses, along with interest income to assess the Company’s performance and allocate resources. Refer to the condensed consolidated financial statements for significant segment expenses and assets regularly provided to the CODM.
Accounting Standards Not Yet Adopted
During December 2023, the Financial Accounting Standards Board (“FASB”) issued ASU 2023-09, Income Taxes (Topic 740) — Improvements to Income Tax Disclosures (“ASU 2023-09”). ASU 2023-09 requires companies to provide annually a tabular reconciliation of the reported income tax expense (or benefit) from continuing operations to the product of the income (or loss) from continuing operations before income taxes and the applicable statutory federal income tax rate using specified categories and to disclose separately reconciling items within certain categories with absolute values equal to or greater than five percent of the product of the income (or loss) from continuing operations before tax and the applicable statutory tax rate. Additionally, ASU 2023-09 requires a public business entity to disclose the year-to-date amount of income taxes paid, net of refunds received, to federal, state, and foreign jurisdictions. If a payment to a single federal, state or foreign jurisdiction equals or exceeds five percent of total income taxes paid, ASU 2023-09 requires separate disclosure of that payment. Finally, ASU 2023-09 requires a public business entity to disclose income (or loss) from continuing operations before income tax expense (or benefit) disaggregated between domestic and foreign jurisdictions and to disclose income tax expense (or benefit) from continuing operations disaggregated between federal, state, and foreign jurisdictions. ASU 2023-09 removes the requirement to disclose the nature and estimate of the range of reasonably possible increases or decreases in the unrecognized tax benefits balance in the next 12 months, or to make a statement that an estimate of the range cannot be made. ASU 2023-09 is effective for the Company for calendar years beginning after December 15, 2025. Early adoption is permitted. The Company is evaluating the impact to its income tax disclosures.
In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses (“ASU 2024-03”) , which requires new tabular disclosures in the notes to consolidated financial statements, disaggregating certain cost and expense categories within relevant captions on the consolidated statements of operations. The prescribed cost and expense categories requiring disaggregated disclosures include purchases of inventory, employee compensation, depreciation, and intangible asset amortization, along with certain other expense disclosures already required by U.S. GAAP that would need to be integrated within the new tabular disaggregated expense disclosures. Additionally, the amendments also require the disclosure of total selling expenses and an entity's definition of those expenses. The amendments in ASU 2024-03 are effective for annual periods beginning after December 15, 2026 and for subsequent interim periods. Early adoption is permitted and the amendments should be applied on a prospective basis, although retrospective application is permitted. The Company is evaluating the impact the new accounting standard will have on its expense disclosures.
NOTE 3 — Investments
The Company has two t ypes of investments: (i) a certificate of deposit and (ii) investments in securities which are classified as available-for-sale.
The entire balance of $ 100 million of the certificate of deposit is included within short-term investments on the condensed consolidated balance sheets as of March 31, 2025 and December 31, 2024.

Change in Option liability — —
Issuances — —
Payments — —
Balance of recurring Level 3 liabilities at end of period $ 6,404 $ 47,164
Short-term Investments
Short-term investments are valued at cost, which approximates fair value. The fair value of the short-term investments is considered a Level 2 fair value measurement because cost basis is not observable in a public market.
Marketable Securities
The fair value of the available-for-sale investments is classified as a Level 1 fair value measurement, because the investments are valued using the most recent quoted prices for identical assets in active markets.
Warrants
The Public Warrants are exercisable for 8,624,974 shares of Class A Common Stock at a price of $ 11.50 per share. The Company may redeem the Public Warrants for $ 0.01 if the last reported trading price of the Company’s Class A Common Stock price equals or exceeds $ 18.00 per share for any 20 trading days within a 30 -trading day period. Additionally, the Public Warrants may be redeemed if the last reported trading price of the Company’s Class A Common Stock equals or exceeds $ 10.00 and is below $ 18.00 by paying a make-whole premium. The Public Warrants expire five years after the Closing Date. The Public Warrants are valued using their quoted and publicly available market prices. Since their fair value is predicated on quoted prices in an active market for identical instruments, the fair value of the Public Warrants is considered a Level 1 fair value measurement.
The Private Placement Warrants are exercisable for 10,900,000 shares of Class A Common Stock at a price of $ 11.50 per share. The Private Placement Warrants expire five years after the Closing Date. The Private Placement Warrants are exercisable on a cashless basis and are non-redeemable as long as they are held by the initial purchasers or their permitted transferees. The Private Placement Warrants and Class A Common Stock issuable upon exercise of the Private Placement Warrants are entitled to registration rights.
The Company uses a Black-Scholes Merton Model to value the Private Placem ent Warrants. Key inputs into the Black-Scholes Merton Model include the last Class A Common Stock closing price of $ 2.63 as of March 31, 2025 with a strike price of $ 11.50 per share. The volatility assumption is based on a blended average of equity volatility of publicly traded companies within the Company’s peer group, the Company's own historical volatility, and the implied volatility of the Public Warrants. The fair value of the Private Placement Warrants is considered a Level 3 fair value measurement.
13
The following table contains the key inputs used in the valuations of the Private Placem ent Warrants:
March 31, 2025 December 31, 2024
Term (in years) 3.19 3.44
Volatility 80.0 % 59.3 %
Risk-free rate 3.8 % 4.2 %
Earnout Shares

The fair value of the Earnout Shares (as defined in Note 6 to the consolidated financial statements included in the 2024 Annual Report) is estimated using a Monte Carlo simulation. The Monte Carlo simulation considers daily simulated stock prices as a proxy for the Company’s daily volume-weighted average share price. Historically, t he volatility assumption is based on a blended average of equity volatility of publicly traded companies within the Company’s peer group, the historical volatility of the Company’s Class A common stock, and the implied volatility of the Public Warrants. For the valuation as of March 31, 2025, the volatility assumption is based on the Company’s own historical volatility, implied volatility on the Company’s own common stock options, and the implied volatility of the Public Warrants.

NOTE 5 — Goodwill and Intangible Assets
Goodwill
Goodwill represents the future economic benefits derived from the Company’s unique market position, the growth attributable to the Net Power Cycle and the Company’s assembled workforce, none of which are individually and separately recognized as intangible assets. Goodwill is allocated to the Company’s sole reportable segment and reporting unit.
The following table presents the changes to goodwill included in the condensed consolidated balance sheets:
March 31, December 31,
$ in thousands 2025 2024
Balance at the beginning of the period $ 359,847 $ 423,920
Impairment ( 359,847 ) —
Measurement adjustments — ( 64,073 )
Balance at the end of the period $ — $ 359,847
During the second quarter of 2024, the Company completed its estimate of deferred taxes as of the Closing Date and finalized its purchase price allocation, which resulted in a measurement adjustment that reduced goodwill by $ 64.1 million .
In March 2025, the Company assessed its goodwill for impairment. Due to a change in the Company’s business plan, as discussed below, and related sustained decrease in the Company’s market capitalization, the Company concluded that it was more likely than not that the fair value was less than its carrying amount as of March 31, 2025. As a result, the Company fully impaired its goodwill and recorded an impairment of $ 359.8 million during the three months ended March 31, 2025, which is included in Goodwill impairment and other charges on the condensed consolidated statements of operations and comprehensive loss.

(1) Software includes $ 0.7 million and $ 0.6 million related to software work-in-progress as of March 31, 2025 and December 31, 2024.
The Company evaluates its long-term assets for impairment when a triggering event occurs. During the quarter ended March 31, 2025 , the Company identified a triggering event due to higher-than-expected indicative cost estimates for its first utility-scale project. The Company has since paused new purchase commitments for the project’s long-lead equipment and has commenced a value engineering exercise to determine project cost reductions and better understand the project’s expected economic feasibility.
As the Company is in the development stage, focusing on developing and commercializing its technology, it assessed its definite-lived intangible assets, the Demonstration Plant, and other corporate assets for impairment as an asset group. In this assessment, management used a probability-weighted cash flow analysis, incorporating estimated cash flows from the deployment of its technology and the value of the underlying intellectual property. Based on the recoverability test, no impairment was required.

As of December 31, 2024, the Company measured redeemable NCI at redemption value . The adjustment to record redeemable NCI at book or redemption value is recorded through Additional paid-in capital on the condensed consolidated statement of mezzanine shareholders' equity and shareholders' equity.
OpCo’s net loss before income tax was attributed to redeemable NCI holders at 64.4 % and 66.2 % for the three months ended March 31, 2025 and 2024, respectively.
NOTE 10 — Share-Based Payments
Aggregate share-based compensation expense, net of forfeitures, was $ 10.2 million and $ 6.3 million for the three months ended March 31, 2025 and 2024, respectively.
Restricted Stock Units
As of March 31, 2025, there have been 980,155 restricted stock units (“RSU”) awarded under the terms of the Net Power Inc. 2023 Omnibus Incentive Plan. As of March 31, 2025, there was $ 5.8 million of unrecognized share-based compensation expense related to unvested RSUs, which the Company expects to recognize over a weighted average period of three years . Generally, RSUs granted to employees and the majority of executives either cliff-vest on the three-year anniversary of the date of grant or vest ratably on each anniversary of the date of grant over a three-year period. Annual awards granted to independent directors cliff-vest on the first anniversary of each award’s grant date.
Additionally, there were 1,257,467 RSUs awarded to certain legacy employees as permitted by the Business Combination agreement (the “Make-Whole Awards”). These RSUs vest upon occurrence of the following events, which are considered performance conditions: (i) commercial operations achieved by the Company’s first utility-scale power plant, and (ii) a fully-executed license agreement and final investment decision achieved for another utility-scale power plant. The Make-Whole Awards expire ten years from the grant date. The Company will record compensation expense related to the Make-Whole Awards from the date the performance conditions are considered probable through the expected vesting dates. As of March 31, 2025, the performance conditions ar e not considered probable, therefore, no c ompensation cost has been recognized related to the Make-Whole Awards.
The following table presents a summary of RSU activity during the three months ended March 31, 2025:

NOTE 11 — Loss per Share
Basic loss per share attributable to shareholders is calculated by dividing net loss attributable to shareholders by the weighted-average number of shares outstanding during the period. Diluted loss per share attributable to shareholders includes the effect of potentially dilutive common shares outstanding.
The following table sets forth the computation of the Company’s basic and diluted loss per share for the following periods:
Three Months Ended March 31,
In thousands, except per share data 2025 2024

Make-Whole Awards 1,257 —
Stock Options 2,460 —
Total 168,123 164,547
Only shares of Class A Common Stock participate in the Company’s undistributed earnings. As such, the Company’s undistributed earnings are allocated entirely to the Class A Common Stock based on the weighted-average number of shares of Class A Common Stock outstanding for the three months ended March 31, 2025 and 2024.
NOTE 12 — Income Taxes
As of March 31, 2025, the Company estimated its annual effective tax rate to be 1.8 %, and recorded a deferred income tax expense of $ 0.4 million, for the quarter. The annual effective tax rate varies from the statutory federal income tax rate due to amounts allocated to NCI, changes in the Company’s valuation allowance and other permanent items.
18
Tax Receivable Agreement
The actual amount and timing of any payments under the Tax Receivable Agreement (“TRA”) will vary depending upon a number of factors, including the timing of exchanges by the OpCo Class A unitholders, the amount and timing of the taxable income the Company generates in the future, and the federal tax rates then applicable, among other factors. The Company recognizes the TRA liability when the amount is probable and estimable.
Due to the Company’s decision to pause new purchase commitments for the project’s long-lead equipment and commencement of a value engineering exercise to determine project cost reductions and better understand the project’s expected economic feasibility, the Company has determined it was not more likely than not that its deferred tax assets subject to the TRA would be realized. Therefore, in March 2025, the Company reduced the TRA liability of $ 21.3 million to zero as payments related to the TRA are not considered probable as of March 31, 2025. The reduction is recorded in Change in Tax Receivable Agreement liability in the condensed consolidated statements of operations and comprehensive loss . If utilization of the Company’s deferred tax assets subject to the TRA become more likely than not in the future, the Company will reassess the probability of payments under the TRA and any such liability will be recognized as an expense in the condensed consolidated statements of operations and comprehensive loss.

Another shareholder supports the Company with regard to general business oversight and with the operation of the Demonstration Plant. These totals are reflected in Research and development on the condensed consolidated statements of operations and comprehensive loss.
BHES JDA
On February 3, 2022, the Company entered into the Original JDA, which was subsequently amended and restated on June 30, 2022 and December 13, 2022 with BHES to invest in, develop, and deploy the Net Power Cycle in collaboration with the Company. The BHES JDA is settled in cash and issuances of equity in exchange for services related to the development and commercialization of the technology. The Company records the expense for services provided by BHES within Research and development on the condensed consolidated
19
statements of operations and comprehensive loss. Upon the issuance of shares during the three months ended March 31, 2025, BHES’s ownership interest exceeded 5%; therefore, they are considered a related party for all periods presented.
The portion of BHES JDA costs that the Company pays with Class A OpCo Units and shares of Class B Common Stock is recorded within Additional paid-in capital on the condensed consolidated balance sheets and the condensed consolidated statement of mezzanine shareholders' equity and shareholders' equity. The following table displays the expense recognized in our consolidated statement of comprehensive income for shares distributed as payment for services rendered under the terms of the BHES JDA during the periods described below:

Total $ 8,247 $ 4,298

Shares issued as payment under the terms of the Amended and Restated JDA are issued at a discount expected to cause a total loss of approximately $ 17.5 million to the Company over the term of the agreement. The Company has incurred inception-to-date losses of $ 9.6 million related to such issuances. Additionally, if the volume-weighted average price of the Company’s stock for ten consecutive trading days (“10-Day VWAP”) immediately preceding the payment date for services under the BHES JDA is less than $ 4.00 per share (the “Floor Price”), an incremental cash payment is required for the difference between the 10-Day VWAP and the Floor Price (the “BHES JDA Make-Whole Payment”). As of March 31, 2025, the Company had $ 2.5 million in current liabilities payable to related parties on the condensed consolidated balance sheets related to the BHES JDA Make-Whole Payment.
BHES may earn additional shares (“BHES Bonus Shares”) if it meets certain proposed project milestones related to the development of our technology. The Company determined that BHES’s achievement of each of these milestones is probable; therefore, the Company recognizes the compensation cost associated with milestone share-based payments ratably over the expected service period. The following table disaggregates the variable share-based compensation payable to BHES should it meet its milestone objectives:

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
The following management’s discussion and analysis (“MD&A”) provides information that management believes is relevant to an assessment and understanding of our condensed consolidated results of operations and financial condition and includes forward-looking statements that involve risks, uncertainties and assumptions, including those described in “Cautionary Note Regarding Forward-Looking Statements” included in the forepart of this Quarterly Report on Form 10-Q (our “Quarterly Report”) and included in Part I, Item 1A Risk Factors in our Annual Report on Form 10-K for the year ended December 31, 2024 (our “Annual Report”), as filed with the SEC on March 12, 2025.
The following MD&A should be read in conjunction with our condensed consolidated financial statements and related notes included in Part 1, Item 1 in this Quarterly Report and our audited consolidated financial statements and related notes included in our Annual Report.
Overview
Net Power is an energy technology company that has developed a novel power generation system (which we refer to as the “Net Power Cycle”) designed to produce reliable and affordable electricity from natural gas while capturing virtually all atmospheric emissions. The Net Power Cycle is designed to inherently capture CO 2 while producing virtually no air pollutants such as SO X , NO X , and other particulates.
Key Factors Affecting Our Prospects and Future Results
We believe that our performance and future success depend on a number of factors that present significant opportunities for us but also pose risks and challenges, including, but not limited to, cost over-runs in the testing and operation of the Demonstration Plant and future utility-scale plants, technical problems with the Net Power Cycle, that could impact performance, potential supply chain issues, changes in tax policies and other incentives supporting carbon capture, our access to the capital needed to finance the development of utility and commercial-scale plants, and development of competing clean-energy technology sooner or at a lesser cost than the Net Power Cycle. Supply chain issues related to the manufacturing and transportation of key equipment, including as a result of tariffs imposed by the U.S. or other countries or other trade barriers, measures, or conflicts, may lead to a delay in our commercialization efforts, which could impact our results of operations, financial condition and prospects. Also, currency fluctuations, inflation, and tariffs and other trade barriers, measures or conflicts may significantly increase freight charges, raw material costs and other expenses associated with our business, and such increased costs could materially and adversely affect our results of operations, financial condition and prospects.
Commencing Commercial Operations
Over the next several years, Net Power plans to conduct additional research and equipment validation testing campaigns at its Demonstration Plant. Additionally, Net Power began purchasing initial long-lead materials for its first utility-scale power plant (“SN1”) in 2024 with the intention of locating SN1 in the Permian Basin of West Texas (“Project Permian”). However, after completing the front-end engineering and design (“FEED”) process in December 2024, the initial cost estimates were higher than originally anticipated. In response, during the first quarter of 2025, Net Power commenced a post-FEED optimization and value engineering process. In March 2025, the Company suspended further long-lead equipment releases but value engineering and certain development work remains in progress. Provided we are successful in our value engineering process, the project would come online no earlier than 2029. We are focused on delivering a project that will catalyze future adoption for utility-scale customers.

In addition to the value engineering process discussed above, major remaining development activities relating to completing construction of SN1 are similar to the activities we previously undertook to design, build, and commission the Demonstration Plant. These activities include: finalizing all permitting, supply and off-take contracts, obtaining the financing required to achieve a final investment decision, and constructing and commissioning the facility.

General and administrative
General and administrative expenses consist primarily of personnel-related expenses associated with our general and administrative organiz ation and professional fees for legal, accounting, and other consulting services. General and administrative expenses increased by $2.3 million , or 36%, fo r the three months ended March 31, 2025, as compared to the same period in 2024. This increase was due to increases in corporate headcount, higher professional fees for engineering and accounting services and franchise taxes.
23
Sales and marketing
Sales and marketing expenses consist primarily of personnel-related costs, consultants and information technology costs directly associated with our sales and marketing activities, which include general publicity efforts for the Company. Sales and marketing expens es increased by $0.4 million , or 58%, for the three months ended March 31, 2025, as compared to the same period in 2024 . This increase was primarily attributable to costs associated with growth in employee headcount.
Research and development
Research and development (“R&D”) expenses consist primarily of labor expenses and fees paid to third parties working on and testing specific aspects of our technology, including testing at our Demonstration Plant and development activities under the BHES JD A. R&D expenses increased by $11.4 million , or 101%, for the three months ended March 31, 2025, as compared to the same period in 2024 . This increase was primarily due to more activity under the BHES JDA and related increased activity at the Demonstration Plant due to the ongoing testing campaign that commenced in the fourth quarter of 2024 and is expected to continue over the next several years. Additionally, the three months ended March 31, 2025 includes a $2.5 million accrual for the BHES JDA Make-Whole Payment. There was no such payment due for the same period in 2024.
Project development
Project development expenses consist of labor expenses and fees paid to third parties developing commercial scale projects. P roject development expenses increased by $4.2 million, or 1,286%, for the three months ended March 31, 2025, as compared to the same period in 2024. Beginning in March 2025, the Company began expensing costs associated with Project Permian as the Company suspended further long lead equipment releases for the project while it performs a value engineering process to evaluate the feasibility of the project. For the three months ended March 31, 2025, the Company expensed $3.8 million of costs related to Project Permian.
Goodwill impairment and other charges
Goodwill impairment and other charges consists of $359.8 million related to goodwill impairment and $56.1 million in construction-in-progress costs associated with Project Permian. The Company fully impaired goodwill during the three months ended March 31, 2025 due to a change in the Company’s business plan and related sustained decrease in the Company’s market capitalization. Additionally, the Company expensed costs associated with the construction of Project Permian as management initiated a value engineering process to assess the project’s feasibility and optimize its design and temporarily paused further long lead equipment releases.
Depreciation, amortization, and accretion
Depreciation, amortization and accretion expenses consist primarily of de preciation on our Demonstration Plant and amortization of intangible assets. Depreciation, amortization and accretion expense increased by $1.6 million , or 8%, for the three months ended March 31, 2025, as compared to the same period in 2024, primarily due to new additions to the Demonstration Plant throughout 2024.
Interest income
Interest income (expense ) decreased by $1.8 million , or 24%, for the three months ended March 31, 2025, as compared to the same period in 2024. Interest income decreased due to lower cash balances and interest rates, partially offset by investment accretion.
Change in Earnout Shares liability and Warrant liability
The change in Earnout Shares liability and Warrant liabili ty was $88.7 million , or 609%, for the three months ended March 31, 2025, as compared to the same period in 2024. The change was primarily due to the changes in
24
the market price of our Class A Common Stock, which correlates to the change in value of our Warrants. The Company’s stock price decreased $7.96 per share during the three months ended March 31, 2025 compared to an increase of $1.29 per share for the three months ended March 31, 2024.
Change in Tax Receivable Agreement liability
The change in Tax Receivable Agreement liability was $21.3 million, or 100.0% , for the three months ended March 31, 2025, as compared to the same period in 2024. During the three months ended March 31, 2025, the the TRA liability of $21.3 million was reduced to zero based on the determination that it was not more likely than not that its deferred tax assets subject to the TRA would be realized. Therefore, payments under the TRA are not considered probable as of March 31, 2025.
Income tax (expense) benefit
Income tax expense was $0.4 million for the three months ended March 31, 2025 , compared to an income tax benefit of $4.0 million for the same period in 2024. This change was due to an increase in the Company’s valuation allowance, partially offset by a favorable permanent difference related to the change in the value of the Warrant liability as compared to the same period in 2024.
Net loss attributable to non-controlling interests
Net loss attributable to non-controlling interest was 64.4% of net loss before income tax for the three months ended March 31, 2025, as compared to 66.2% of net loss for the three months ended March 31, 2024. The change in the non-controlling interests was due to exchanges by OpCo members of Class A OpCo units for Class A PubCo shares, partially offset by the additional issuance of Class A OpCo units under the BHES JDA.
Liquidity and Capital Resources
Our principal sources of liquidity are cash, short-term investments and investments in highly liquid available-for-sale securities. Historically, our sources of liquidity have also included raising capital through the sale of equity. We may issue additional equity securities in the future. We measure liquidity in terms of our ability to fund the cash requirements of our R&D activities and our near-term business operations, including our contractual obligations and other commitments. Our current liquidity needs primarily involve R&D activities for the ongoing development of our technology, general and administrative costs, and progress certain development activities related to SN1.
The following table summarizes our liquidity position:
March 31, December 31,
2025 2024
Cash and cash equivalents $ 300,030 $ 329,230
Short-term investments 100,000 100,000
Available-for-sale securities 100,726 100,972
Total liquidity $ 500,756 $ 530,202
The short-term investments are comprised of a single six-month certificate of deposit custodied by a domestic banking institution, and the available-for-sale securities are comprised of investment grade, fixed income securities. Additionally, our current liabilities were $21.4 million a t March 31, 2025.
We believe we have the ability to manage our operating costs, including R&D expenditures, such that our existing liquidity will be sufficient to fund our obligations for the next 12 months following the filing of this Report. We believe that our current sources of liquidity on hand should be sufficient to fund our general corporate operating expenses as we work to commercialize our technology, but certain costs are not reasonably estimable at this time and we may require additional funding. Specifically, we will require additional funding in
25
order to successfully construct our first utility-scale plant and to originate additional Net Power plant opportunities.
Cash Flow Summary
The following table shows our cash flows from operating activities, investing activities and financing activities for the presented periods:
Three Months Ended March 31,
2025 2024
Net cash used in operating activities $ (20,374) $ (2,663)
Net cash used in investing activities $ (8,764) $ (105,669)
Net cash used in financing activities $ (50) $ —
Operating Activities
Cash used in operating activiti es increased $17.7 million f or the three months ended March 31, 2025, as compared to the same period in 2024. Our net cash used in operating activities to date have been primarily comprised of payroll, material and supplies, facilities expense, and professional services related to R&D, including the BHES JDA, and general and administrative activities. This change was primarily due to higher R&D costs, including costs incurred under the BHES JDA, as we commenced the testing campaign at our Demonstration Plant during the fourth quarter of 2024, project development costs and the build out of the Company during 2024. We exp ect our cash used in operating activities to increase significantly before we start to generate any material cash inflows from our operations as costs related to Project Permian are being expensed pending the results of the value engineering process initiated during the three months ended March 31, 2025.
Investing Activities
During the three months ended March 31, 2025, net cash used in investing activities decreased $96.9 million as compared to the same period in 2024. Our cash used in investing activities for the three months ended March 31, 2024 primarily reflects th e initial investments in available-for-sale securities during that period.
Financing Activities
Our cash provided by financing activ ities was generally consistent for the three months ended March 31, 2025, as compared to the same period in 2024.
Commitments and Contractual Obligations
Asset Retirement Obligation
We hold a lease for approximately 218,900 square feet of land under the Demonstration Plant. In addition, we have an oxygen supply agreement with the lessor to supply oxygen to the Demonstration Plant. The lease expires on the earlier of (i) January 1, 2031 and (ii) the termination of our oxygen supply agreement with the lessor. The term of the oxygen supply agreement expires on January 1, 2030 with automatic 12-month renewal terms. The oxygen supply agreement may be terminated by us or by the lessor upon 24 months’ written notice prior to the expiration date of its current term. The underlying lease requires the removal of all equipment and the obligation to restore the land to post-clearing grade level, which has resulted in the recognition of an asset retirement obligation liability of $3.3 million and $3.3 million as of March 31, 2025 and December 31, 2024, respectively.
Leases
As of March 31, 2025, future minimum lease payments attributable to the Company’s operating and finance lease arrangements are appr oximately $3.0 million and $0.3 million , respectively .
26
On March 7, 2025, the Company entered into a building lease agreement for a warehouse in La Porte, Texas with an initial term of 62 months commencing in April 2025. The lease contains a renewal option of five years. The future minimum lease payments associated with this lease are approximately $2.2 million.
The Company leases corporate office space in Durham, North Carolina, and Houston, Texas. The lease for the Company’s corporate office space in Houston, Texas, commenced July 11, 2024. The Company also entered into a land lease agreement with a subsidiary of Occidental Petroleum, a related party, on March 8, 2024, for land in West T exas with commencement on December 1, 2024.
Additionally, the Company leases two office trailers at the Demonstration Plant in La Porte, Texas, with an effective date of September 1, 2024. The lease has a term of 24 months and contains a purchase option whereby the Company may purchase the trailers at the end of the lease term; therefore, the Company classified the lease as a finance lease.
Joint Development Agreement
As of March 31, 2025 and December 31, 2024, we have committed to funding a portion of the remaining development costs incurred under the BHES JDA through a com bination of cash and equity. The BHES JDA’s total value is $140 million, which assumes a fixed price per share. As of March 31, 2025, we recognized approximately $38.5 million of inception-to-date cash expenses and approximately $38.5 million of inception-to-date share-based expenses related to the BHES JDA. In addition, the Company may be required to make additional cash payments to BHES during periods when the volume-weighted average price of our Class A Common Stock is less than $4.00 per share in the 10 trading days preceding applicable quarterly share issuances under the terms of the BHES JDA (the “JDA Make-Whole Payment”). As of March 31, 2025, we recognized a liability of $2.5 million related to the JDA Make-Whole Payment.
Off-Balance Sheet Arrangements
As of March 31, 2025 and December 31, 2024, we have not en gaged in any off-balance sheet arrangements, as defined in the rules and regulations of the SEC.
Purchase Commitments
As of March 31, 2025, we have committed to purchase certain components of industrial machinery for use at our Demonstration Plant and at SN1. The total gross commitments total ed $146.4 million . As of March 31, 2025, there was $95.0 million remain ing related to these commitments.
Critical Accounting Policies and Estimates
There have been no material changes to our discussion of critical accounting estimates from those set forth in our Annual Report.
Emerging Growth Company Accounting Election

Section 102(b)(1) of the Jumpstart our Business Startups Act of 2012 (the “JOBS Act”) exempts emerging growth companies (“EGCs”) from being required to comply with new or revised financial accounting standards until private companies are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect not to take advantage of the extended transition period and comply with the requirements that apply to non-EGCs, and any such election to not take advantage of the extended transition period is irrevocable. We expect to be an EGC at least through the end of 2025 and will have the benefit of the extended transition period. We intend to take advantage of the benefits of this extended transition period.
