**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 Company's ability to utilize its net operating loss and tax credit carryforwards effectively; (iii) the capital-intensive nature of the Company's business model, which will require the Company to raise additional capital in the future; (iv) 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; (viii) risks related to the Company's arrangements with third parties for the development, commercialization and deployment of technology associated with the Company's technology; (ix) risks related to the Company's other strategic investors and partners; (x) the Company's ability to successfully commercialize its operations; (xi) the availability and cost of raw materials; (xii) the ability of the Company's supply base to scale to meet the Company's anticipated growth; (xiii) the Company's ability to update the design, construction, and operations of its technology; (xiv) the impact of potential delays in discovering manufacturing and construction issues; (xv) the possibility of damage to the Company's Texas facilities as a result of natural disasters; (xvi) the ability of commercial plants using the Company's technology to efficiently provide net power output; (xvii) the Company's ability to obtain and retain licenses; (xviii) the Company's ability to establish an initial commercial scale plant; (xix) the Company's ability to license to large customers; (xx) the Company's ability to accurately estimate future commercial demand; (xxi) the Company's ability to adapt to the rapidly evolving and competitive natural and renewable power industry; (xxii) the Company's ability to comply with all applicable laws and regulations; (xxiii) the impact of public perception of fossil fuel-derived energy on the Company's business; (xxiv) any political or other disruptions in gas producing nations; (xxv) the Company's ability to protect its intellectual property and the intellectual property it licenses; (xxvi) risks relating to data privacy and cybersecurity, including the potential for cyberattacks or security incidents that could disrupt our or our service providers' operations; (xxvii) current and potential litigation that has been and may be instituted against the Company; and (xviii) 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 the Company's 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.

<u>[**Table of Contents**](ex102executiversugrantnoti.htm)</u>

***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. Segment expenses and other segment items are provided to the CODM on the same basis as disclosed in the condensed consolidated financial statements. The measure of segment assets is reported on the Company's condensed consolidated balance sheet as total assets.

***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.

The cost of securities sold, if any, is based on the specific-identification method. During the three and six months ended June 30, 2025 and 2024, there were no securities sold. There were no credit losses recognized during the three and six months ended June 30, 2025 and 2024. The Company established no allowances for credit losses as of June 30, 2025 and December 31, 2024. The Company's long-term available-for-sale investments mature through June 2027.

**NOTE 4 — Fair Value Measurements**

| Balance of recurring Level 3 liabilities at end of period | $4817 | $36175 | $4817 | $36175 |

---

***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 observable, but not in an active market.

***Available-for-sale 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 June 8, 2028. 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 June 8, 2028. The Private Placement Warrants are

------

<u>[**Table of Contents**](ex102executiversugrantnoti.htm)</u>

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 Placement Warrants. Key inputs into the Black-Scholes Merton Model include the last Class A Common Stock closing price of $2.47 as of June 30, 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.

The following table contains the key inputs used in the valuations of the Private Placement Warrants:

---

| | | |
|:---|:---|:---|
| | **June 30, 2025** | **December 31, 2024** |
| Term (in years) | 2.94 | 3.44 |
| Volatility | 79.0% | 59.3% |
| Risk-free rate | 3.6% | 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, the 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 June 30, 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.

The following table contains the key inputs used in the valuations of the Earnout Shares:

---

| | | |
|:---|:---|:---|
| | **June 30, 2025** | **December 31, 2024** |
| Term (in years) | 0.94 | 1.43 |
| Volatility | 85.0% | 59.7% |
| Risk-free rate | 3.9% | 4.1% |

---

**NOTE 5 — Goodwill and Intangible Assets**

***Goodwill***

Goodwill represented 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 was 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:

---

| | | |
|:---|:---|:---|
| | **June 30,** | **December 31,** |
| *$ in thousands* | **2025** | **2024** |
| Balance at the beginning of the period | $359847 | $423920 |
| Impairment | (359847) |  |
| Measurement adjustments |  | (64073) |
| Balance at the end of the period | $— | $359847 |

---

------

<u>[**Table of Contents**](ex102executiversugrantnoti.htm)</u>

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 of its goodwill was less than its carrying amount as of March 31, 2025. As a result, the Company fully impaired its goodwill and recognized an impairment of $359.8 million during the six months ended June 30, 2025, which is included in Goodwill impairment and other charges on the condensed consolidated statements of operations and comprehensive loss.

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, due to higher-than expected indicative cost estimates for its first utility-scale project, the Company identified a triggering event for evaluation of impairment of its long-term assets. 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. The results of the recoverability test performed in March 2025 indicated that no impairment was required, and the Company did not identify any indicators that the asset group may be impaired as of June 30, 2025.

As of December 31, 2024, Construction-in-progress in the table above includes capitalized costs related to Project Permian, the Company's first utility-scale facility. During the first quarter of 2025, the Company initiated a value engineering process to assess the project's feasibility and optimize its design and temporarily paused further long lead equipment releases. Consequently, $56.1 million of costs previously included in Construction-in-progress were expensed during the first quarter of 2025. This amount is included in Goodwill impairment and other charges in the condensed consolidated statements of operations and comprehensive loss.

| Non-controlling interest holders | 64.4% | 64.4% |
| NET Power Inc. | 35.6% | 35.6% |

---

The Company measures redeemable NCI each quarter at the higher of its book value or its redemption value. As of June 30, 2025, the Company measured redeemable NCI at book value. 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 June 30, 2025 and 2024, respectively. OpCo's net loss before income tax was attributed to redeemable NCI holders at 64.4% and 66.2% for the six months ended June 30, 2025 and 2024, respectively.

***Performance Stock Units***

As of June 30, 2025, there was $1.1 million of unrecognized share-based compensation expense related to unvested performance stock units ("PSUs").

During the second quarter of 2025, there were 524,000 PSUs awarded to certain executives for which the vesting occurs upon the achievement of specific market-based conditions related to the Company's financial performance over a three-year period, modified based on the Company's Relative Total Shareholder Return ("TSR") and subject to final vesting based on the participant's continued employment through the end of the requisite service period. The amount of awards that will ultimately vest for the PSU can range from 0% to 200% based on the TSR calculated over a three-year period. The fair value of the PSUs was determined using the Monte Carlo Simulation model and is being expensed over the three-year vesting period. The assumptions used to calculate the fair value of these awards were:

---

| | |
|:---|:---|
| Weighted average expected life | 3 years |
| Risk-free interest rates | 3.9% |
| Expected volatility | 80.0% |

---

***Stock Options***

As of June 30, 2025, there was $4.5 million of unrecognized share-based compensation expense related to stock options.

The stock options granted to employees during the second quarter of 2025 vest on the one-year anniversary of the date of grant. The Company will recognize compensation expense from the grant date through the expected vesting date. The fair value of the Company's stock option grants was estimated utilizing the following assumptions using the Black-Scholes Merton model:

---

| | |
|:---|:---|
| Weighted average expected life | 3 years |
| Risk-free interest rates | 3.87% |
| Expected volatility | 86.0% |

| Unvested, end of period | 6506 | $5.60 |

---

***Restricted Stock Units***

As of June 30, 2025, there was $7.4 million of unrecognized share-based compensation expense related to unvested restricted stock units ("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.

**NOTE 12 — Income Taxes**

As of June 30, 2025, the Company estimated its annual effective tax rate to be 1.96%, and recorded a deferred income tax benefit of $1.6 million and $1.2 million for the three and six months ended June 30, 2025. 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.

On July 4, 2025, the One Big Beautiful Bill Act ("OBBBA") was enacted in the U.S. The OBBBA includes significant provisions, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, modifications to the international tax framework and the restoration of favorable tax treatment for certain business provisions. The legislation has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. We are currently assessing its impact on our consolidated financial statements, however, do not expect a material impact to the financial statements at this time.

***Tax Receivable Agreement***

In March 2025, due to the Company's decision to pause new purchase commitments for Project Permian's long-lead equipment and commencement of a value engineering exercise to determine project cost reductions and better understand Project Permian's expected economic feasibility, the Company determined it was not more likely than not that its deferred tax assets subject to the Tax Receivable Agreement ("TRA") would be realized and therefore, reduced the TRA liability to zero as payments under the TRA were not considered probable. Accordingly, in March 2025, the Company recognized a $21.3 million reduction in the Tax Receivable Agreement liability, which is recorded in Change in Tax Receivable Agreement liability in the condensed consolidated statements of operations for the six months ended June 30, 2025.

On May 12, 2025, pursuant to its rights under the TRA, the Company delivered to the agent of the TRA holders notice of the Company's intent to terminate the TRA (the "Early Termination Notice"). No early termination payment was payable for any TRA holder. The Early Termination Notice became final and binding on June 12, 2025.

The Company had $29.5 million and $6.5 million in current liabilities payable to related parties as of June 30, 2025 and December 31, 2024, respectively, on the condensed consolidated balance sheets related to the following services. These related party payables are unsecured and are due on demand.

***Master Services Agreements***

A significant shareholder provides the Company with patent administration services related to the development of the Net Power Cycle. These totals are included in General and administrative on 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 statements of operations and comprehensive loss. Upon the issuance of shares during the six months ended June 30, 2025, BHES's ownership interest exceeded 5%; therefore, it is 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 tables display the expense recognized in the consolidated statement of comprehensive income for

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 $11.7 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 June 30, 2025, the Company had $1.3 million in current liabilities payable to related parties on the condensed consolidated balance sheets related to the BHES JDA Make-Whole Payment. For the three and six months ended June 30, 2025, the Company incurred $1.4 million and $3.9 million 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:

***BHES Limited Notice to Proceed***

Through June 30, 2025, the Company has incurred $41.5 million under a Letter of Limited Notice to Proceed for the Purchase of KPEP Long Lead Time Items with BHES (the "BHES LNTP"), as amended, for the purchase of long-lead materials necessary for the procurement and manufacture of the turboexpander and related key process equipment and machinery for the Company's first utility-scale power plant, along with related fees and services.

**NOTE 14 — Commitments and Contingencies**

***Litigation***

From time to time, the Company is party to certain legal actions and claims. Other than any such ordinary routine litigation incidental to the business and except as described below, the Company is not currently a party to, nor is our property currently subject to, any material legal proceedings, and the Company is not aware of any such proceedings contemplated by governmental authorities.

On April 18, 2025, an alleged stockholder of the Company (the "Plaintiff"), individually and on behalf of all others similarly situated, filed a putative class action complaint for violation of federal securities laws against the Company, its Chief Executive Officer, President and Interim Chief Financial Officer, its former Chief Financial Officer and its former President and Chief Operating Officer (collectively, the "Defendants") in the United States District Court for the Middle District of North Carolina (the "Complaint"). The Complaint purports to bring a federal securities class action on behalf of a class of persons and entities other than the Defendants who acquired the Company's securities between June 9, 2023 and March 7, 2025 and asserts violations of Sections 10(b) and 20(a) of the Exchange Act and Rule 10b-5 promulgated thereunder. The Complaint alleges, among other things, that the Defendants made materially false and misleading statements related to the Company's business, operations and prospects, including the timing and costs of developing Project Permian. The Plaintiff seeks, among other things, certification of a class, an award of unspecified compensatory damages, interest, costs and expenses, including attorneys' fees and expert fees.

On May 29, 2025, an alleged stockholder of the Company, filed a derivative suit on behalf of the Company against the Company's Chief Executive Officer, President and Interim Chief Financial Officer, its former Chief Financial Officer, its former President and Chief Operating Officer and its board of directors in the United States District Court for the Middle District of North Carolina, asserting claims for breach of fiduciary duty, unjust enrichment, abuse of control, gross mismanagement, waste of corporate assets, and violations of federal securities laws (the "Derivative Complaint"). These claims are predicated on the same allegedly false and misleading statements regarding the time and capital needed to complete Project Permian that are the subject of the Complaint outlined above.

The Company intends to vigorously defend against the claims brought in both matters. In light of the complexity and ongoing and uncertain nature of the outstanding proceedings and inquiries, at this time we are unable to estimate a reasonably possible financial loss or range of financial loss, if any, that we may incur to resolve or settle these matters.

***Asset Retirement Obligation***

Under the terms of the lease for the Demonstration Plant, the Company is required to remove the Demonstration Plant and restore the land to post-clearing grade level. During 2024, the Company revised the estimate of its asset retirement obligation as a result of additional construction at the Demonstration Plant. The following table reconciles the beginning and ending balances of the asset retirement obligation as of the dates presented:

***Unconditional Purchase Obligations***

The Company has committed to purchase industrial components for installation at its Demonstration Plant and its first commercial power plant. The Company pays for these components in installments aligned to contractual milestones. In accordance with ASC Topic 440, *Commitments*, the Company does not recognize these commitments on the condensed consolidated balance sheets.

**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 10, 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 a clean 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 CO2 while producing virtually no air pollutants such as SOX, NOX, 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 energy technologies 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.

Specifically, on July 4, 2025, President Trump signed into law the One Big Beautiful Bill Act ("OBBBA"), a large piece of tax and spending legislation that has specific material effects for Net Power's intended SN1 project and future pipeline. The OBBBA preserved the core elements of the 45Q tax credit for carbon sequestration and use, including eligibility for programs to efficiently monetize the credits (i.e., direct pay and transferability). The OBBBA also created parity in 45Q credit value for carbon emissions used in enhanced oil recovery ("EOR"); eligible projects capturing carbon emissions for EOR that would have previously been eligible for a $60/ton credit will now be eligible for the full value of $85/ton. Net Power expects this increase in credit value to materially improve the economics for projects capturing emissions for EOR, strengthening economics for projects specifically in the Permian Basin and improving the pathway for broad commercialization of the Net Power technology, including projects capturing carbon emissions for permanent sequestration. The OBBBA included additional other provisions with expected fewer material effects on Net Power projects and indirect effects on the broader market for clean power; the full implications of those changes are not yet clear.

Additionally, the Trump Administration has started the process to change regulations on new natural gas-fired power plants. Currently, the U.S. Environmental Protection Agency's regulations for new gas turbines that run above a 40% capacity factor require such facilities to meet a 90% capture rate by 2032. These regulations were proposed to be repealed on June 11, 2025. The implications of the potential repeal of these regulations are uncertain at this time, but we do not expect such repeal to have a material impact on the market for Net Power's technology.

***Commencing Commercial Operations***

Over the next several years, Net Power plans to conduct additional research and equipment validation testing campaigns at its Demonstration Plant. In 2024, Net Power began purchasing initial long-lead materials for its first utility-scale power plant ("SN1") 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 indicative cost estimate at that time was 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 as of August 2025. 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.

During the second quarter of 2025, alongside ongoing value engineering efforts to lower the cost of Net Power's core product, we initiated a techno-economic study to assess the integration of combustion gas turbines into Net Power projects. This configuration enhances project economics and accelerates market deployment, aligning with customers' increasing demand for scalable, reliable power solutions while advancing our mission to provide clean, dependable energy globally. We are exploring the adoption of this configuration for Project Permian and future Net Power projects.

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.

**Key Components of Results of Operations**

We are a development stage company and our historical results may not be indicative of our future results. Accordingly, the drivers of our future financial results, as well as the components of such results, may not be comparable to our historical or future results of operations.

*General and administrative*

General and administrative expenses consist primarily of personnel-related expenses associated with our general and administrative organization and professional fees for legal, accounting, information technology, and other consulting services. During the second quarter of 2025, we terminated the employment of our former Chief Operating Officer, our former Chief Financial Officer, our former Chief Accounting Officer, and certain other employees. Such terminations resulted in the payment of severance to these employees, as well as the acceleration of vesting of certain stock-based compensation. We do not expect to incur such costs in future quarters. General and administrative expenses increased by $5.8 million, or 74%, for the three months ended June 30, 2025, as compared to the same period in 2024. This increase was primarily due to $3.1 million of severance costs and $1.1 million of accelerated share-based compensation related to the termination of certain executive management. Additionally, we incurred greater professional fees for engineering and tax consulting as well as higher information technology expenses for the three months ended June 30, 2025, as compared to the same period in 2024.

*Sales and marketing*

Sales and marketing expenses consist primarily of personnel-related and consultant costs directly associated with our sales and marketing activities, which include general publicity efforts for the Company. Sales and marketing expenses increased by $0.6 million, or 70%, for the three months ended June 30, 2025, as compared

------

<u>[**Table of Contents**](ex102executiversugrantnoti.htm)</u>

to the same period in 2024. This increase was primarily attributable to costs associated with growth in employee headcount as well as severance costs and related accelerated stock-based compensation.

*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 JDA. R&D expenses increased by $11.1 million, or 72%, for the three months ended June 30, 2025, as compared to the same period in 2024. This increase was primarily due to more activity under the BHES JDA and ongoing validation testing campaigns at the Demonstration Plant that began in the fourth quarter of 2024. The Company also expanded its engineering headcount growth to support technology development efforts. Additionally, the Company incurred $1.4 million related to the JDA Make-Whole Payment for the three months ended June 30, 2025; no such payment was incurred 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. Project development expenses increased by $26.3 million, or 3,030%, for the three months ended June 30, 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 June 30, 2025, the Company incurred $19.5 million under the BHES LNTP related to certain milestones and $7.3 million of costs related to Project Permian.

*Depreciation, amortization, and accretion*

Depreciation, amortization and accretion expenses consist primarily of depreciation 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 June 30, 2025, as compared to the same period in 2024, primarily due to new additions to the Demonstration Plant.

*Interest income*

Interest income decreased by $3.6 million, or 39%, for the three months ended June 30, 2025, as compared to the same period in 2024. Interest income decreased due to lower interest-bearing cash and investment balances, decline in interest rates, and lower investment accretion.

*Change in Earnout Shares liability and Warrant liability*

The change in Earnout Shares liability and Warrant liability decreased by $14.8 million, or 91%, for the three months ended June 30, 2025, as compared to the same period in 2024. The change was primarily due to the changes in 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 $0.16 per share during the three months ended June 30, 2025 compared to a decrease of $1.56 per share for the three months ended June 30, 2024.

*Income tax benefit*

Income tax benefit was $1.6 million for the three months ended June 30, 2025, compared to an income tax benefit of $2.4 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 June 30, 2025, as compared to 66.2% of net loss for the three months ended June 30, 2024. The change in

------

<u>[**Table of Contents**](ex102executiversugrantnoti.htm)</u>

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.

*General and administrative*

General and administrative expenses increased by $8.2 million, or 58%, for the six months ended June 30, 2025, as compared to amounts for the six months ended June 30, 2024. This increase was primarily due to $3.1 million of severance costs and $1.1 million of share-based compensation related to the termination of certain management team members. Growth in employee headcount and higher stock based compensation also contributed to an overall increase in compensation expense. Additionally, we incurred greater professional fees for engineering, accounting, and legal services as well as higher information technology costs in the six months ended June 30, 2025, as compared to the six months ended June 30, 2024.

*Sales and marketing*

Sales and marketing expenses consist primarily of personnel-related costs and consultants costs directly associated with our sales and marketing activities, which include general publicity efforts for the Company. Sales and marketing expenses increased by $1.1 million, or 65%, for the six months ended June 30, 2025, as

------

<u>[**Table of Contents**](ex102executiversugrantnoti.htm)</u>

compared to the six months ended June 30, 2024. This increase was primarily attributable to increased headcount as well as severance costs and related accelerated stock-based compensation.

*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 JDA. R&D expenses increased by $22.5 million, or 84%, for the six months ended June 30, 2025, as compared to amounts for the six months ended June 30, 2024. This increase was primarily due to the timing of development activities under the BHES JDA and the validation testing campaigns at the Demonstration Plant that began in the fourth quarter of 2024. The Company also expanded its engineering headcount growth to support technology development efforts. Additionally, R&D expenses for the six months ended June 30, 2025 include $3.9 million for the BHES JDA Make-Whole Payments; 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. Project development expenses increased by $30.4 million, or 2,354%, for the six months ended June 30, 2025, as compared the six months ended June 30, 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 six months ended June 30, 2025, the Company incurred $19.5 million under the BHES LNTP related to certain milestones and $11.1 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 six months ended June 30, 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*

Our depreciation, amortization, and accretion expenses consist primarily of depreciation on our Demonstration Plant and amortization of intangible assets. Depreciation, amortization, and accretion expense increased by $3.3 million, or 8%, for the six months ended June 30, 2025, as compared to amounts for the same period in 2024, primarily due to new additions to the Demonstration Plant.

*Interest income*

Interest income decreased by $5.4 million, or 32%, for the six months ended June 30, 2025, as compared to amounts for the same period in 2024. This decrease was due to lower interest-bearing cash and investment balances, decline in interest rates, and lower investment accretion.

*Change in Earnout Shares liability and Warrant liability*

The change in Earnout Shares liability and Warrant liability increased by $73.9 million, or 4,423%, for the six months ended June 30, 2025, as compared to the same period in 2024. This increase is primarily due to the change in the fair value of the Private Placement Warrants and Public Warrants, which was driven by changes

------

<u>[**Table of Contents**](ex102executiversugrantnoti.htm)</u>

in our stock price. The Company's stock price decreased $8.12 per share during the six months ended June 30, 2025 compared to a decrease of $0.27 per share for the six months ended June 30, 2024.

*Change in Tax Receivable Agreement liability*

In March 2025, the Company reduced the TRA liability of $21.3 million to zero as payments related to the TRA were not considered probable. In May 2025, pursuant to its rights under the TRA, the Company delivered to the agent of the TRA holders notice of the Company's intent to terminate the TRA (the "Early Termination Notice"). No early termination payment was payable to any TRA holder. The Early Termination Notice became final and binding on June 12, 2025.

*Income tax benefit*

Our income tax benefit decreased by $5.2 million for the six months ended June 30, 2025, as compared to amounts for the six months ended June 30, 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. In addition, the Company finalized deferred taxes as of the Closing Date of the Business Combination 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 six months ended June 30, 2025, as compared to 66.2% of net loss for the six months ended June 30, 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 costs to progress certain development activities related to SN1.

The following table summarizes our liquidity position:

---

| | | |
|:---|:---|:---|
| | **June 30,** | **December 31,** |
| *in thousands* | **2025** | **2024** |
| Cash and cash equivalents | $284024 | $329230 |
| Short-term investments |  | 100000 |
| Available-for-sale securities | 188287 | 100972 |
| &nbsp;&nbsp;Total liquidity | $472311 | $530202 |

---

The available-for-sale securities are comprised of investment grade, fixed income securities, and the short-term investments are comprised of a single 12-month certificate of deposit custodied by a domestic banking institution. Additionally, our current liabilities were $41.8 million at June 30, 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

------

***Operating Activities***

Cash used in operating activities increased $34.1 million for the six months ended June 30, 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 validation testing campaigns at our Demonstration Plant during the fourth quarter of 2024, project development costs, and the expansion of the Company's corporate infrastructure throughout 2024 and into 2025. We expect 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.

***Investing Activities***

During the six months ended June 30, 2025, net cash used in investing activities decreased $118.5 million as compared to the same period in 2024. Cash used in investing activities for the six months ended June 30, 2025 primarily reflects the maturity of the Company's certificate of deposit and the reinvestment of those funds into available-for-sale securities, along with capital expenditures related to the Demonstration Plant and Project Permian during the period in which costs were capitalized. Cash used in investing activities for the six months ended June 30, 2024 primarily reflects the initial investments in available-for-sale securities as well as capital expenditures related to Project Permian and the Demonstration Plant during that period.

***Financing Activities***

Our cash provided by financing activities was generally consistent for the six months ended June 30, 2024, 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 $3.4 million and $3.3 million as of June 30, 2025 and December 31, 2024, respectively.

------

<u>[**Table of Contents**](ex102executiversugrantnoti.htm)</u>

***Leases***

The Company leases corporate office space in Durham, North Carolina, and Houston, Texas. The Company also leases land in West Texas for Project Permian from a subsidiary of Occidental Petroleum. Additionally, the Company leases two office trailers at the Demonstration Plant, as well as a warehouse, in La Porte, Texas.

As of June 30, 2025, future minimum lease payments attributable to the Company's operating and finance lease arrangements are approximately $5.0 million and $0.2 million, respectively.

***Joint Development Agreement***

As of June 30, 2025 and December 31, 2024, we have committed to funding a portion of the remaining development costs incurred under the BHES JDA through a combination of cash and equity. The BHES JDA's total value is $140 million, which assumes a fixed price per share. As of June 30, 2025, we recognized approximately $46.8 million of inception-to-date cash expenses and approximately $46.8 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. As of June 30, 2025, the Company had $1.3 million in current liabilities payable to related parties on the condensed consolidated balance sheets related to the BHES JDA Make-Whole Payment. For the three and six months ended June 30, 2025, the Company incurred $1.4 million and $3.9 million related to the BHES JDA Make-Whole Payment.

***Off-Balance Sheet Arrangements***

As of June 30, 2025 and December 31, 2024, we have not engaged in any off-balance sheet arrangements, as defined in the rules and regulations of the SEC.

***Purchase Commitments***

As of June 30, 2025, we have committed to purchase certain components of industrial machinery for use at our Demonstration Plant and at SN1. The total gross commitments totaled $146.7 million. As of June 30, 2025, there was $70.4 million remaining 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.

**Item 3. Quantitative and Qualitative Disclosures About Market Risk**

We are a smaller reporting company as defined by Rule 12b-2 of the Exchange Act and are not required to provide the information otherwise required under this item.

<u>[**Table of Contents**](ex102executiversugrantnoti.htm)</u>

**Item 4. Controls and Procedures**

*Evaluation of Disclosure Controls and Procedures*

Under the supervision and with the participation of our management, including our principal executive officer who is also our principal financial officer, we conducted an evaluation of the effectiveness of our disclosure controls and procedures, as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, as of the end of the fiscal quarter ended June 30, 2025. Based on this evaluation, our principal executive officer and our principal financial officer concluded that our disclosure controls and procedures were effective as of June 30, 2025.

Disclosure controls and procedures are designed to ensure that information required to be disclosed by us in our Exchange Act reports is recorded, processed, summarized, and reported within the time periods specified in the SEC's rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

*Changes in Internal Control over Financial Reporting*

No changes in our internal control over financial reporting occurred during the fiscal quarter ended June 30, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

**Part II - Other Information**

**Item 1. Legal Proceedings**

From time to time, the Company is party to certain legal actions and claims. Other than any such ordinary routine litigation incidental to the business and except as described below, we are not currently a party to, nor is our property currently subject to, any material legal proceedings, and we are not aware of any such proceedings contemplated by governmental authorities.

On April 18, 2025, an alleged stockholder (the "Plaintiff"), individually and on behalf of all others similarly situated, filed a putative class action complaint for violation of federal securities laws against us, our Chief Executive Officer, President and Interim Chief Financial Officer, our former Chief Financial Officer and our former President and Chief Operating Officer (collectively, the "Defendants") in the United States District Court for the Middle District of North Carolina (the "Complaint"). The Complaint purports to bring a federal securities class action on behalf of a class of persons and entities other than the Defendants who acquired our securities between June 9, 2023 and March 7, 2025 and asserts violations of Sections 10(b) and 20(a) of the Exchange Act and Rule 10b-5 promulgated thereunder. The Complaint alleges, among other things, that the Defendants made materially false and misleading statements related to our business, operations and prospects, including the timing and costs of developing Project Permian. The Plaintiff seeks, among other things, certification of a class, an award of unspecified compensatory damages, interest, costs and expenses, including attorneys' fees and expert fees.

On May 29, 2025, an alleged stockholder of the Company filed a derivative suit on behalf of the Company against our Chief Executive Officer, President and Interim Chief Financial Officer, our former Chief Financial Officer, our former President and Chief Operating Officer and our board of directors in the United States District Court for the Middle District of North Carolina, asserting claims for breach of fiduciary duty, unjust enrichment, abuse of control, gross mismanagement, waste of corporate assets, and violations of federal securities laws (the "Derivative Complaint"). These claims are predicated on the same allegedly false and misleading statements regarding the time and capital needed to complete Project Permian that are the subject of the Complaint outlined above.

We intend to vigorously defend against the claims brought in both matters. In light of the complexity and ongoing and uncertain nature of the outstanding proceedings and inquiries, at this time we are unable to estimate a reasonably possible financial loss or range of financial loss, if any, that we may incur to resolve or settle these matters.

**Item 1A. Risk Factors**

As a smaller reporting company, we are not required to provide the information called for by this Item. However, for a discussion of the material risks, uncertainties and other factors that could have a material effect on us, please refer to Part I, Item 1A. "Risk Factors" in our Annual Report.

**Item 2. Unregistered Sales of Equity Securities and Use of Proceeds**

*Unregistered Sales of Equity Securities*

On May 7, 2025, the Company issued 1,247,582 shares of Class B Common Stock and OpCo issued 1,247,582 Class A units to BHES as payment for costs incurred pursuant to the Amended and Restated JDA during the fourth quarter of 2024. The issuances by the Company and OpCo were exempt from registration under the Securities Act by virtue of Section 4(a)(2) of the Securities Act. These transactions did not involve any public offering, any underwriters, any underwriting discounts or commissions, or any general solicitation or advertising.

**Item 3. Defaults Upon Senior Securities**

None.

Not applicable.

**Item 5. Other Information**

*Insider Trading Arrangements*

During the three months ended June 30, 2025, none of our directors or "officers" (as such term is defined in Rule 16a-1(f) under the Exchange Act) adopted or terminated a "Rule 10b5-1 trading arrangement" or "non-Rule 10b5-1 trading arrangement" (as each term is defined in Item 408(a) of Regulation S-K).
