Cautionary Note Regarding Forward-Looking Statements

This Quarterly Report on Form 10-Q (the “Quarterly Report”) contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). We have based these forward-looking statements on our current expectations and projections about future events. All statements, other than statements of present or historical fact included in this Quarterly Report regarding our future financial performance, as well as our strategy, future operations, financial position, estimated revenues, losses, projected costs, prospects, plans and objectives of management are forward-looking statements. Any statements that refer to projections, forecasts or other characterizations of future events or circumstances, including any underlying assumptions, are forward-looking statements. In some cases, you can identify forward-looking statements by terminology such as “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “forecast,” “intends,” “may,” “might,” “plan,” “possible,” “potential,” “predict,” “project,” “should,” “target,” “will,” “would” or the negative of such terms or other similar expressions. These forward-looking statements are based on management’s current expectations, assumptions, hopes, beliefs, intentions and strategies regarding future events and are based on currently available information as to the outcome and timing of future events. Although we believe such expectations and assumptions to be reasonable, they are inherently uncertain and involve a number of risks and uncertainties that are beyond our control. In addition, management’s assumptions about future events may prove to be inaccurate. All readers are cautioned that the forward-looking statements contained in this Quarterly Report are not guarantees of future performance and we cannot assure any reader that such statements will be realized or that the forward-looking events and circumstances will occur.

As a result of a number of known and unknown risks and uncertainties, our actual results or performance may be materially different from those expressed or implied by these forward-looking statements. Some factors that could cause actual results to differ include:

•our financial and business performance, including risk of uncertainty in our financial projections and business metrics and any underlying assumptions thereunder;

•changes in our business and strategy, future operations, financial position, estimated revenues and losses, projected costs, prospects and plans;

•our ability to execute our business model, including market acceptance of our planned products and services and achieving sufficient production volumes at acceptable quality levels and prices;

•our ability to maintain our listing on the New York Stock Exchange (“NYSE”);

•changes in domestic and foreign business, market, financial, political, legal conditions and applicable laws and regulations;

•our ability to grow market share in our existing markets or new markets we may enter;

•our ability to achieve and maintain profitability in the future;

•our ability to access sources of capital to finance operations, growth and future capital requirements;

•our ability to maintain and enhance our products and brand, and to attract and retain customers;

•our ability to find new partners for product offerings;

•the success of strategic relationships with third parties;

•our ability to scale in a cost-effective manner;

•developments and projections relating to our competitors and industry;

•supply chain disruptions;

•our ability to protect our intellectual property (“IP”);

•the actions of stockholders and the related impact on the price of our common stock;

3

•expectations regarding the time during which we will be an emerging growth company under the Jumpstart Our Business Startups Act of 2012, as amended;

•our ability to find and retain critical employee talent and key personnel;

•our ability to successfully manage the transition process to a new executive team;

•the possibility that we may be adversely impacted by other economic, business, and/or competitive factors;

•future exchange and interest rates;

•the outcome of any known and unknown litigation and regulatory proceedings; and

•other risks and uncertainties, including those disclosed under “Item 1A. Risk Factors” contained in Part I of our Annual Report on Form 10-K for the year ended December 31, 2022 (our “Annual Report”) filed with the Securities and Exchange Commission (“SEC”) on March 29, 2023, as supplemented by the risk factor previously disclosed in Part II, Item 1A. Risk Factors in our Quarterly Report for the period ended March 31, 2023, and the risk factors and other cautionary statements contained in other filings that have been made or will be made with the SEC by the Company.

Given these risks and uncertainties, you should not place undue reliance on these forward-looking statements. Should one or more of the risks or uncertainties described in this Quarterly Report, or should underlying assumptions prove incorrect, actual results and plans could differ materially from those expressed in any forward-looking statements. Our SEC filings are available publicly on the SEC’s website at www.sec.gov.

You should read this Quarterly Report with the understanding that our actual future results, levels of activity and performance as well as other events and circumstances may be materially different from what we expect. We qualify all of our forward-looking statements by these cautionary statements.

Notes to the Unaudited Consolidated Financial Statements

Note 1—Organization and Basis of Presentation

Background

Heliogen, Inc. and its subsidiaries (collectively, “Heliogen” or the “Company”), is involved in the development and commercialization of next generation concentrated solar energy. We are developing a modular, artificial intelligence (“AI”)-enabled, concentrated solar energy plant that will use an array of mirrors to reflect sunlight and capture, concentrate, store and convert it into cost-effective energy on demand. Unless otherwise indicated or the context requires otherwise, references in our consolidated financial statements to “we,” “us,” or “our” and similar expressions refer to Heliogen.

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information. Accordingly, these unaudited consolidated financial statements do not include all information or notes required by GAAP for annual financial statements. In the opinion of management, the unaudited consolidated financial statements have been prepared on the same basis as the annual financial statements and include all adjustments, consisting of only normal recurring adjustments, necessary for fair statement.

The results reported in these unaudited consolidated financial statements are not necessarily indicative of the results that may be reported for the entire year. These unaudited 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, 2022, filed with the Securities and Exchange Commission on March 29, 2023.

Certain immaterial prior period amounts have been reclassified to conform to current period presentation. Such changes did not have a material impact on our financial position or results of operations.

Liquidity

The Company has evaluated whether there were conditions and events, considered in the aggregate, which raise substantial doubt as to the Company’s ability to continue as a going concern within one year after the original issuance date of the unaudited consolidated financial statements. During the six months ended June 30, 2023 and the year ended December 31, 2022, the Company incurred net losses of $32.2 million and $142.0 million, respectively. The Company expects to continue to generate operating losses in the next few years.

As of June 30, 2023, the Company had liquidity of $107.8 million, consisting of $43.5 million of cash and cash equivalents and $64.3 million of investments, and no substantial debt. Management believes it has the ability to manage operating costs and capital expenditures such that its existing cash, cash equivalents and investments will be sufficient to fund its operations and capital expenditures for the next twelve months following the filing of this Quarterly Report on Form 10-Q.

The Company’s long-term liquidity will depend on its ability to (i) successfully complete current projects within budget, (ii) raise additional capital through the issuance of additional equity or debt securities, (iii) sign additional projects at a profit, (iv) obtain funding and receive payment for research and development (“R&D”) projects, (v) implement project cost reductions to reduce the expected cash outflows and (vi) manage operating costs. There is no assurance that the Company will be successful in achieving all or any of these items. If the Company is unsuccessful in achieving all or any of these items, the Company may be forced to delay, reduce or eliminate some or all of its R&D programs, product expansion or commercialization efforts, any of which could adversely affect its business prospects, or the Company may be unable to continue operations.

Notes to the Unaudited Consolidated Financial Statements

Use of Estimates

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported in our consolidated financial statements and the accompanying notes. Despite our intention to establish accurate estimates and reasonable assumptions, actual results could differ materially from such estimates and assumptions.

Recent Accounting Standards

In January 2017, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, which eliminates the second step of the previous two-step quantitative test of goodwill impairment. Under the new guidance, the quantitative test consists of a single step in which the carrying amount of the reporting unit is compared to its fair value. An impairment charge would be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the amount of the impairment would be limited to the total amount of goodwill allocated to the reporting unit. The guidance does not affect the existing option to perform the qualitative assessment for a reporting unit to determine whether the quantitative impairment test is necessary. The new guidance will be effective for smaller reporting companies for fiscal years beginning after December 15, 2022.

Services Revenue

Project revenue consists of amounts recognized under contracts with customers for the development, construction and delivery of commercial-scale concentrated solar energy facilities. The Company’s recognized project revenue is associated with a commercial-scale demonstration agreement (“CSDA”) executed with Woodside Energy (USA) Inc. (“Woodside”) in March 2022.

Engineering services revenue consists of amounts recognized under contracts with customers for the provision of engineering, R&D, or other similar services in our field of expertise. Engineering service contracts typically span several years and we recognize revenue over time as customers receive and consume the benefit of such services.

Revenue recognized during the three and six months ended June 30, 2023 and 2022 includes non-governmental customers in the United States (“U.S.”) and Europe.

Grant Revenue

The Company’s grant revenue is primarily related to the Company’s award from the U.S. Department of Energy (the “DOE Award”) related to costs incurred during such periods that are reimbursable under the DOE Award.

Provision for Contract Losses

During the three and six months ended June 30, 2023, we recognized a total provision for contract losses of $20 thousand and $0.4 million, respectively, associated with our operations in Germany. During the three and six months ended June 30, 2023, we amortized $0.9 million and $1.3 million, respectively, of the previously recognized contract loss provisions as a reduction to cost of services revenue incurred during the three and six months ended June 30, 2023 based on percentages of completion.

During the six months ended June 30, 2022, we recognized a total provision for contract losses of $33.7 million driven primarily by the CSDA, of which we amortized $3.2 million as a reduction to cost of sales incurred during 2022. No provision for contract losses was recognized during the three months ended June 30, 2022.

Performance Obligations

Revenue recognized under contracts with customers relates solely to the performance obligations satisfied during the six months ended June 30, 2023 with no revenue recognized from performance obligations satisfied in prior periods. As of June 30, 2023, we had approximately $37.0 million of transaction prices allocated to remaining performance obligations from our customer contracts, we expect to recognize approximately 43% as revenue over the next 12 months and the remainder to be recognized thereafter through 2026.

Note 3—Warrants

Public Warrants and Private Warrants

The Company’s warrant liabilities as of June 30, 2023 include public warrants (the “Public Warrants”) and private placement warrants (the “Private Warrants,” and together with the Public Warrants, the “Public and Private Warrants”). The Public Warrants and Private Warrants permit warrant holders to purchase in the aggregate approximately 8.3 million shares and approximately 0.2 million shares, respectively, of the Company’s common stock at an exercise price of $11.50 per share. The Public and Private Warrants became exercisable on March 18, 2022 and expire on December 30, 2026, or earlier upon redemption or liquidation. The Public and Private Warrants are recorded as liabilities on the consolidated balance sheets and measured at fair value at each reporting date, with the change in fair value reported in gain (loss) on warrant remeasurement on the consolidated statements of operations.

Project Warrants

In connection with the concurrent execution of the CSDA with Woodside in March 2022, the Company issued warrants permitting Woodside to purchase approximately 0.9 million shares of the Company’s common stock at an exercise price of $0.01 per share (the “Project Warrants”). The Project Warrants expire upon the earlier of a change in control of the Company or March 28, 2027 and vest pro rata with certain payments required to be made by the customer under the CSDA. The fair value of the Project Warrants upon issuance was $4.96 per warrant based on the closing price of the Company’s common stock on March 28, 2022, less the exercise price. The Project Warrants are recorded as equity on the consolidated balance sheets.

Notes to the Unaudited Consolidated Financial Statements

During the three and six months ended June 30, 2023, approximately 0.1 million and 0.2 million, respectively, of Project Warrants vested with a value of $63 thousand and $0.1 million, respectively, which was recognized as additional paid-in capital. During the three and six months ended June 30, 2022, approximately 0.2 million of Project Warrants vested with a value of $89 thousand and $0.4 million, respectively, which was recognized as additional paid-in capital. From the issuance date of the Project Warrants on March 28, 2022 to June 30, 2023, a total of approximately 0.5 million of Project Warrants vested with a total value of $0.8 million, which was recognized as additional paid-in capital.

Collaboration Warrants

In connection with the concurrent execution of a collaboration agreement (the “Collaboration Agreement”) with Woodside in March 2022, the Company issued warrants permitting Woodside to purchase approximately 3.6 million shares of the Company’s common stock at an exercise price of $0.01 per share (the “Collaboration Warrants”). Under the Collaboration Agreement, Woodside will assist us in defining product offerings that use our modular technology for potential customers in Australia. The Collaboration Warrants expire upon the earlier of a change in control of the Company or March 28, 2027. Of these warrants, (i) approximately 1.8 million warrants vested immediately upon execution of the Collaboration Agreement and (ii) approximately 1.8 million warrants will vest based on certain specified performance goals under the Collaboration Agreement. The fair value of the Collaboration Warrants upon issuance was $4.96 per warrant based on the closing price of the Company’s common stock on March 28, 2022, less the exercise price.

The Collaboration Warrants are recorded as equity on the consolidated balance sheets and the related expense is being recognized ratably as selling, general and administrative (“SG&A”) expense over the estimated service period. As of June 30, 2023, the Company has a prepaid expense of $6.3 million for the Collaboration Warrants, of which $2.0 million was classified as current and $4.3 million was classified as long-term. The Company recognized SG&A expense related to the vesting of the Collaboration Warrants of $0.5 million and $0.6 million during the three months ended June 30, 2023 and 2022, respectively, and of $1.0 million and $0.6 million during the six months ended June 30, 2023 and 2022, respectively. As of June 30, 2023, the remaining estimated period is approximately 3.2 years.

Vendor Warrants

On April 19, 2022, the Company issued warrants to purchase approximately 0.1 million shares of the Company’s common stock, at an exercise price of $0.01 per share (“Vendor Warrants”), to a vendor as compensation for services to be performed by the vendor. The Vendor Warrants vest in twelve equal monthly installments. The Vendor Warrants are recorded as equity on the consolidated balance sheets and had a fair value upon issuance of $0.3 million, to be recognized ratably over one year as SG&A expense. During the six months ended June 30, 2023 and 2022, the Company recognized $0.1 million and $0.1 million, respectively, of share-based compensation expense, included in SG&A, related to the portion of the Vendor Warrants that vested during the period. As of April 2023, the Vendor Warrants are fully vested.

The cost of securities sold is based on the specific-identification method. During the six months ended June 30, 2023, there were no sales of investments. During the six months ended June 30, 2022, we realized losses of $0.2 million on the sale of investments, included in other income, net on our consolidated statements of operations related to $65.8 million in proceeds from the sale of investments.

There were no credit losses recognized during the three and six months ended June 30, 2023 and 2022 and no allowance for credit losses as of June 30, 2023 and December 31, 2022.

Note 5—Fair Value of Financial Instruments

The Company’s assets and liabilities measured at fair value on a recurring basis are summarized in the following table by fair value measurement level:

$ in thousands	Level	June 30, 2023		December 31, 2022
Assets:
Investments	1	$	64,309	$	97,504

Contingent consideration (2)	3	1,590		353

________________

(1)Included in warrant liabilities on the consolidated balance sheets.

(2)Included in other long-term liabilities on the consolidated balance sheets.

Private Warrants. The fair value of the Private Warrants approximates the fair value of the Public Warrants due to the existence of similar redemption provisions. As a result, the Company has determined that the fair value of the Private Warrants at a specific date would be similar to that of the Public Warrants, and thus their fair value is determined by using the closing price of the Public Warrants, which was $0.05 as of June 30, 2023.

Contingent Consideration. The contingent consideration was measured at fair value using a probability-weighted cash-flow method. The key inputs used in the valuation for the contingent consideration as of June 30, 2023 included the timing and probability of payment.

The following table summarizes the activities of our Level 3 fair value measurement:

Note 8—Goodwill and Intangible Assets

Goodwill

The Company had goodwill related to the acquisition of HelioHeat GmbH, a private limited liability company in Germany engaged in the development, planning and construction of renewable energy systems and components, including a novel solar receiver.

During the first quarter of 2023, the Company performed a goodwill impairment assessment driven by the sustained decline in the Company’s market capitalization below the Company’s carrying value. Management concluded that it is more likely than not that the fair value of our reporting unit was less than its carrying amount as of March 31, 2023. As a result, the Company fully impaired goodwill and recognized a $1.0 million charge during the three months ended March 31, 2023. The Company had no impairments of goodwill recognized during the six months ended June 30, 2022.

The changes in the carrying amount of goodwill are as follows:

Note 10—Equity

Stockholders Rights Plan

On April 16, 2023, the Company’s Board of Directors (the “Board”) declared a dividend of one preferred share purchase right (“Right”) for each outstanding share of the Company’s common stock to the stockholders of record as of the close of business on April 28, 2023, and adopted a limited duration stockholder rights plan, effective immediately, as set forth in the Rights Agreement, dated as of April 16, 2023 (the “Rights Agreement”), by and between the Company and Continental Stock Transfer & Trust Company, as rights agent. The Rights will be exercisable only if a person or group (an “acquiring person”) acquires or launches a tender or exchange offer to acquire beneficial ownership (which includes certain synthetic equity interests) of 12.5% or more of the Company’s outstanding common stock (20% for certain passive institutional investors as described in the Rights Agreement). Once the Rights become exercisable, each Right will entitle its holder (other than the acquiring person, whose rights will become void) to purchase for $3.50, subject to adjustment, additional shares of our common stock having a market value of twice such exercise price. In addition, the Rights Agreement has customary flip-over and exchange features. The Rights will expire on April 17, 2024 unless the rights are earlier redeemed or exchanged by the Company. The Rights Agreement will reduce the likelihood that any entity, person or group gains control of Heliogen through open market accumulation without paying all stockholders an appropriate control premium or without providing our Board sufficient time to make informed judgments and take actions that are in the best interests of all stockholders.

Note 13—Income Taxes

We calculate our quarterly tax provision pursuant to the guidelines in Accounting Standards Codification (“ASC”) 740, Income Taxes. ASC 740 requires companies to estimate the annual effective tax rate for current year ordinary income. In calculating the effective tax rate, permanent differences between financial reporting and taxable income are factored into the calculation, and temporary differences are not. The estimated annual effective tax rate represents the Company’s estimate of the tax provision in relation to the best estimate of pre-tax ordinary income or loss. The estimated annual effective tax rate is then applied to year-to-date ordinary income or loss to calculate the year-to-date interim tax provision. The relationship between our income tax provision or benefit and our pre-tax book income or loss can vary significantly from period to period considering, among other factors, the overall level of pre-tax book income or loss and changes in the blend of jurisdictional income or loss that is taxed at different rates and changes in valuation allowances. The income tax provision was $2 thousand for the three and six months ended June 30, 2023, respectively. The income tax benefit of $0.1 million and $0.7 million for the three and six months ended June 30, 2022, respectively, is primarily attributable to our operations in Germany. Any income tax benefit associated with the pre-tax loss for the three and six months ended June 30, 2023 and 2022, resulting primarily from the U.S. jurisdiction, is offset by a full valuation allowance.

In assessing the realizability of deferred tax assets, we consider whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Based upon the analysis of federal and state deferred tax balances, future tax projections and availability of taxable income in the carryback period, we recorded a full valuation allowance against the federal and state deferred tax assets for the six months ended June 30, 2023 and the year ended December 31, 2022.

The Company is subject to the provisions of ASC Subtopic 740-10, Accounting for Uncertainty in Income Taxes. This standard defines the threshold for recognizing the benefits of tax return positions in the financial statements as more-likely-than-not to be sustained by the relevant taxing authority and requires measurement of a tax position meeting the more-likely-than-not criterion, based on the largest benefit that is more than 50% likely to be realized. If upon performance of an assessment pursuant to this subtopic, management determines that uncertainties in tax positions exist that do not meet the minimum threshold for recognition of the related tax benefit, a liability is recorded in the consolidated financial statements. The Company recognizes interest and penalties, if any, related to unrecognized tax benefits as a component of income tax expense. We do not have material unrecognized tax benefits for uncertain tax positions.

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 consolidated results of operations and financial condition. The following discussion includes forward-looking statements that involve risks, uncertainties and assumptions, including those described in “Cautionary Note Regarding Forward-Looking Statements” included in the fore-part in 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, 2022 (our “Annual Report”), as filed with the Securities and Exchange Commission on March 29, 2023, as supplemented by the risk factor previously disclosed in Part II, Item 1A. Risk Factors in our Quarterly Report for the period ended March 31, 2023.

The MD&A should be read in conjunction with our consolidated financial statements and related notes included in Part I Item 1 in this Quarterly Report and our audited consolidated financial statements as of December 31, 2022, included in our Annual Report.

Overview

Heliogen, Inc. and its subsidiaries (collectively, “Heliogen,” the “Company,” “we,” “us,” or “our”) is a leader in next generation concentrated solar energy. We are developing a modular, AI-enabled, concentrated solar energy plant that will use an array of mirrors to reflect sunlight and capture, concentrate, store and convert it into cost-effective energy on demand. Our product offering will deliver industrial process steam around the clock using thermal energy storage based on proven technology. This steam can also be used to produce green hydrogen when coupled with a solid oxide electrolyzer. Our next generation system will have the ability to cost-effectively generate and store thermal energy at very high temperatures, which enables cost effective production of electricity and higher temperature industrial process heat. The inclusion of a thermal energy storage system distinguishes our solution from clean energy provided by typical photovoltaic and wind installations which do not produce thermal energy and are only able to produce energy intermittently unless battery storage is added. The system will be configurable for several applications, including carbon-free industrial-grade heat and steam (for use in industrial processes), clean power (electricity), and generation of green hydrogen, based on a customer’s needs.

Recent Developments

Lancaster Offtake Agreement. In June 2023, we executed a definitive contract with The City of Lancaster, California to produce green hydrogen at our Proxima project to be purchased by Lancaster for the city’s growing green hydrogen fuel needs.

Results of Operations

Heliogen is undergoing a significant transition as it moves from design to testing and implementation of its innovative supercritical CO2 power generation system. In March 2022, we secured a contract to engineer and construct a 5 MWe commercial-scale concentrated solar energy facility with Woodside Energy (USA) Inc. (“Woodside”) in Mojave, California with a total transaction price of $45.5 million and received an award from the U.S. Department of Energy (the “DOE”) of $39.0 million (the “DOE Award”) to support the project, of which $3.9 million will be paid directly by the DOE to another party providing services under the DOE Award at our direction. We remain in the early stages of commercializing our technology and investing in research and development (“R&D”) and infrastructure necessary to achieve these goals. As a result, we have historically incurred operating losses. However, we remain focused on achieving sufficient scale and efficiency improvements through technological progress and additional learning to ultimately achieve attractive levels of profitability.

25

How We Generate Revenue

We primarily generate revenue by contracting with owner-operators to build turnkey facilities that deploy Heliogen’s technology. Our services revenue derived from customer contracts is primarily recognized over time using the incurred costs method for our contracts with customers that include projects under development and engineering and design services. Engineering service contracts typically span several years and we recognize revenue over time as customers receive and consume the benefit of such services. Additionally, we have government contracts which are accounted for as grant revenue and are recognized only when there is reasonable assurance that the entity will comply with any conditions attached to the grant and the grant funds will be received.

Cost of Conducting Our Business

Cost of revenue consists primarily of direct material, labor and subcontractor costs related to our revenue contracts. Additionally, we have indirect costs related to contract performance, such as indirect labor, supplies, tools and allocated depreciation.

Revenue and Gross Loss

During the three months ended June 30, 2023, we recognized total revenue of $1.4 million, a decrease of $1.0 million compared to total revenue of $2.4 million for the three months ended June 30, 2022. The decrease was driven by a reduction in costs incurred related to the project to develop a commercial-scale facility for the three months ended June 30, 2023 compared to the same period in 2022, primarily as a result of long-lead items that were paid during the early phase of the project in 2022. We anticipate less costs to be incurred in the current phase of the project until we finalize our front-end engineering design. As a result, we recognized a decrease in services revenue of $0.1 million related to the commercial-scale demonstration agreement (“CSDA”) with Woodside and a decrease in grant revenue of $0.9 million related to the reimbursable costs incurred under the DOE Award for the three months ended June 30, 2023 compared to the same period in 2022.

During the three months ended June 30, 2023, we recognized a gross loss of $0.1 million, a change of $0.3 million compared to gross loss of $0.4 million for the three months ended June 30, 2022. The change was primarily driven by a decrease of $0.3 million in share-based compensation expense attributable to employees working directly on the CSDA project.

Selling, General and Administrative

The following table summarizes selling, general and administrative (“SG&A”) expenses:

	Three Months Ended

Other selling, general and administrative	8,964		6,460		2,504
Total selling, general and administrative	$	17,652	$	22,403	$	(4,751)

During the three months ended June 30, 2023, we recognized SG&A expense of $17.7 million, a decrease of $4.8 million compared to SG&A expense of $22.4 million for the three months ended June 30, 2022. The decrease was primarily driven by a reduction in share-based compensation as a result of no longer recognizing expense due to forfeitures from prior periods and graded vesting schedules for awards issued prior to our business combination with Athena Technology Acquisition Corp. (“Athena”). The decrease was partially offset by an increase of $1.0 million in employee compensation primarily driven by headcount growth to support our commercial operations and increases in professional and consulting services of $1.6 million.

Research and Development

The following table summarizes R&D expenses:

	Three Months Ended

Total research and development	$	4,946	$	5,905	$	(959)

During the three months ended June 30, 2023, we recognized R&D expense of $4.9 million, a decrease of $1.0 million compared to R&D expense of $5.9 million for the three months ended June 30, 2022. The decrease was primarily driven by a reduction of $2.3 million in other R&D direct costs due to focusing our R&D efforts on select strategic priorities and a decrease of $0.4 million in share-based compensation expense. This was offset by an increase of $1.8 million in employee compensation primarily driven by headcount growth.

27

Warrant Remeasurement

During the three months ended June 30, 2023, we recognized a loss of $0.1 million, a change of $8.3 million compared to a gain of $8.3 million for the three months ended June 30, 2022, related to the change in fair value of our outstanding Public and Private Warrants. The change in fair value of the Public and Private Warrants are highly correlated to changes in our stock price.

Other Income (Expense), Net

During the three months ended June 30, 2023, we recognized other income of $0.8 million, a change of $0.9 million compared to other expense of $0.1 million for the three months ended June 30, 2022. The change is primarily attributable to a gain of $0.8 million in asset accretion given the rising interest rate environment for our investments in available-for-sale securities.

Revenue and Gross Loss

During the six months ended June 30, 2023, we recognized total revenue of $3.3 million, a decrease of $2.6 million compared to total revenue of $5.9 million for the six months ended June 30, 2022. The decrease was driven by a reduction in costs incurred related to the project to develop a commercial-scale facility for the six months ended June 30, 2023 compared to the same period in 2022, primarily as a result of long-lead items that were paid during the early phase of the project in 2022. We anticipate less costs to be incurred in the current phase of the project until we finalize our front-end engineering design. As a result, we recognized a decrease in services revenue of $1.2 million related to the CSDA with Woodside and a decrease in grant revenue of $1.4 million related to the reimbursable costs incurred under the DOE Award for the six months ended June 30, 2023 compared to the same period in 2022.

During the six months ended June 30, 2023, we recognized a gross loss of $0.6 million, a change of $34.1 million compared to gross loss of $34.7 million for the six months ended June 30, 2022. The change was primarily driven by the recognition of a contract loss provision during the six months ended June 30, 2022 of $33.7 million primarily related to the CSDA and a decrease of $0.7 million in share-based compensation expense attributable to employees working directly on the project.

Selling, General and Administrative

The following table summarizes SG&A expenses:

	Six Months Ended
	June 30,
$ in thousands	2023		2022		$ Change
Employee compensation, excluding share-based compensation	$	11,841	$	9,042	$	2,799

During the six months ended June 30, 2023, we recognized SG&A expense of $21.8 million, a decrease of $20.6 million compared to SG&A expense of $42.5 million for the six months ended June 30, 2022. The decrease was primarily driven by a reduction in share-based compensation, which included a net reduction of $12.5 million during the six months ended June 30, 2023, as a result of stock options forfeited in connection with the termination of our former Chief Executive Officer and a net reduction of $0.9 million as a result of RSU awards forfeited in connection with the termination of certain employees in the first quarter of 2023. The remaining decrease in share-based compensation expense was a result of an expected reduction in expense over time due to graded vesting schedules for awards issued prior to our business combination with Athena and the impact of forfeitures. The decrease was partially offset by an increase of $2.8 million in employee compensation primarily driven by headcount growth to support our commercial operations and increases in professional and consulting services of $3.0 million.

Total research and development	$	10,206	$	15,280	$	(5,074)

29

During the six months ended June 30, 2023, we recognized R&D expense of $10.2 million, a decrease of $5.1 million compared to R&D expense of $15.3 million for the six months ended June 30, 2022. The decrease was driven by a reduction of $6.6 million in other R&D direct costs due to focusing our R&D efforts on select strategic priorities, a decrease of $1.5 million in share-based compensation expense and was offset by an increase of $3.0 million in employee compensation primarily driven by headcount growth.

Impairment Charges

During the first quarter of 2023, we fully impaired goodwill, resulting in a $1.0 million impairment charge due to a sustained decrease in our market capitalization. We had no impairment charges for the six months ended June 30, 2022. Refer to Note 8—Goodwill and Intangible Assets for additional information.

Warrant Remeasurement

During the six months ended June 30, 2023, we recognized a gain of $0.3 million, a decrease of $12.1 million compared to a gain of $12.3 million for the six months ended June 30, 2022, related to the change in fair value of our outstanding Public and Private Warrants. The change in fair value of the Public and Private Warrants are highly correlated to changes in our stock price.

Other Income (Expense), Net

During the six months ended June 30, 2023, we recognized other income of $0.6 million, a change of $0.8 million compared to other expense of $0.2 million for the six months ended June 30, 2022. The change is primarily attributable to a gain of $1.7 million in asset accretion given the rising interest rate environment for our investments in available-for-sale securities, partially offset by a loss of $1.2 million related to the change in estimated fair value of the contingent consideration associated with the acquisition of HelioHeat GmbH based on the revised probability of payment.

Liquidity and Capital Resources

Our principal sources of liquidity are cash and investments on hand, which are short-term in duration and highly liquid, and cash receipts from customers and government grants. Our principal uses of cash are expenditures related to project development and completion, as well as R&D and SG&A expenditures in support of our technology development and operational support and growth efforts.

Total liquidity, including cash and cash equivalents and available-for-sale investments are as follows:

$ in thousands	August 3, 2023		June 30, 2023
Cash and cash equivalents	$	46,940	$	43,498
Investments	53,077		64,309
Total liquidity	$	100,017	$	107,807

We have evaluated whether there were conditions and events, considered in the aggregate, which raise substantial doubt as to our ability to continue as a going concern within one year after the original issuance date of our unaudited consolidated financial statements. During the six months ended June 30, 2023 and the year ended December 31, 2022, the Company incurred net losses of $32.2 million and $142.0 million, respectively. We expect to continue to generate operating losses in the next few years.

Our liquidity as of August 3, 2023 was $100.0 million, compared to $107.8 million as of June 30, 2023. The decrease in our liquidity is due to funding our operations and continued work on our projects. We believe we have the ability to manage our operating costs and capital expenditures such that our existing cash, cash equivalents and investments will be sufficient to fund our operations and capital expenditures for the next twelve months following the filing of this Quarterly Report.

30

Our long-term liquidity will depend on our ability to (i) successfully complete current projects within budget, (ii) raise additional capital through the issuance of additional equity or debt securities, (iii) sign additional projects at a profit, (iv) obtain funding and receive payment for R&D projects, (v) implement project cost reductions to reduce the expected cash outflows and (vi) manage operating costs. There is no assurance that we will be successful in achieving all or any of these items. If we are unsuccessful in achieving all or any of these items, we may be forced to delay, reduce or eliminate some or all of our R&D programs, product expansion or commercialization efforts, any of which could adversely affect our business prospects, or we may be unable to continue operations.

Summary of Cash Flows

The following table provides a summary of our cash flows:

	Six Months Ended
	June 30,
$ in thousands	2023		2022
Net cash used in operating activities	$	(38,357)	$	(31,360)
Net cash provided by (used in) investing activities	34,158		(96,646)
Net cash provided by (used in) financing activities	1,323		(387)

Net Cash from Operating Activities. Net cash used in operating activities was $38.4 million for the six months ended June 30, 2023 compared to net cash used in operating activities of $31.4 million for the six months ended June 30, 2022. The $7.0 million increase in the net cash used in operating activities was primarily driven by higher operating costs related to the growth of our operations and costs incurred related to our projects.

Net Cash from Investing Activities. Net cash provided by investing activities was $34.2 million for the six months ended June 30, 2023 compared to net cash used in investing activities of $96.6 million for the six months ended June 30, 2022. For the six months ended June 30, 2023, we received net proceeds from the maturities of available-for-sale securities of $35.0 million to fund our operations.

For the six months ended June 30, 2022, we had net cash invested in available-for-sale securities of $93.2 million as we invested the funds received in 2021 from the closing of the business combination with Athena and capital expenditures of $3.5 million in construction in progress to support the ramp-up of commercial operations, machinery, equipment and improvements for our new Long Beach manufacturing facility, and office and computer equipment to support our headcount growth.

Net Cash from Financing Activities. Net cash provided by financing activities was $1.3 million for the six months ended June 30, 2023 compared to net cash used in financing activities of $0.4 million for the six months ended June 30, 2022. The change was primarily driven by $1.3 million of other financing costs paid in the six months ended June 30, 2022 in connection with the business combination with Athena.

Cash Requirements

Our material cash requirements from known contractual and other obligations consist of our long-term operating leases, which are primarily for real estate.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated, as of the end of the period covered by this Quarterly Report, the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Based on that evaluation, and as a result of the material weaknesses in our internal control over financial reporting described in our Annual Report, our Chief Executive Officer and Chief Financial Officer concluded that, as of June 30, 2023, our disclosure controls and procedures were not effective.

Changes in Internal Control over Financial Reporting

The Company had a change in the executive team and on February 5, 2023, our Chief Accounting Officer was appointed to Interim Chief Financial Officer and an Interim Controller was appointed. In June and July 2023, the Company hired a Controller and a Chief Financial Officer, respectively. The previous Interim Chief Financial Officer continues to serve as our Chief Accounting Officer. Other than in connection with changes in personnel and executing upon the implementation of the remediation measures described in our Annual Report and the associated changes to our internal control over financial reporting, there were no changes in our internal control over financial reporting that occurred during the quarter ended June 30, 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Organization and Basis of Presentation

Note 1—Organization and Basis of Presentation

Background

Heliogen, Inc. and its subsidiaries (collectively, “Heliogen” or the “Company”), is involved in the development and commercialization of next generation concentrated solar energy. We are developing a modular, artificial intelligence (“AI”)-enabled, concentrated solar energy plant that will use an array of mirrors to reflect sunlight and capture, concentrate, store and convert it into cost-effective energy on demand. Unless otherwise indicated or the context requires otherwise, references in our consolidated financial statements to “we,” “us,” or “our” and similar expressions refer to Heliogen.

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information. Accordingly, these unaudited consolidated financial statements do not include all information or notes required by GAAP for annual financial statements. In the opinion of management, the unaudited consolidated financial statements have been prepared on the same basis as the annual financial statements and include all adjustments, consisting of only normal recurring adjustments, necessary for fair statement.

The results reported in these unaudited consolidated financial statements are not necessarily indicative of the results that may be reported for the entire year. These unaudited 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, 2022, filed with the Securities and Exchange Commission on March 29, 2023.

Certain immaterial prior period amounts have been reclassified to conform to current period presentation. Such changes did not have a material impact on our financial position or results of operations.

Liquidity

The Company has evaluated whether there were conditions and events, considered in the aggregate, which raise substantial doubt as to the Company’s ability to continue as a going concern within one year after the original issuance date of the unaudited consolidated financial statements. During the six months ended June 30, 2023 and the year ended December 31, 2022, the Company incurred net losses of $32.2 million and $142.0 million, respectively. The Company expects to continue to generate operating losses in the next few years.

As of June 30, 2023, the Company had liquidity of $107.8 million, consisting of $43.5 million of cash and cash equivalents and $64.3 million of investments, and no substantial debt. Management believes it has the ability to manage operating costs and capital expenditures such that its existing cash, cash equivalents and investments will be sufficient to fund its operations and capital expenditures for the next twelve months following the filing of this Quarterly Report on Form 10-Q.

The Company’s long-term liquidity will depend on its ability to (i) successfully complete current projects within budget, (ii) raise additional capital through the issuance of additional equity or debt securities, (iii) sign additional projects at a profit, (iv) obtain funding and receive payment for research and development (“R&D”) projects, (v) implement project cost reductions to reduce the expected cash outflows and (vi) manage operating costs. There is no assurance that the Company will be successful in achieving all or any of these items. If the Company is unsuccessful in achieving all or any of these items, the Company may be forced to delay, reduce or eliminate some or all of its R&D programs, product expansion or commercialization efforts, any of which could adversely affect its business prospects, or the Company may be unable to continue operations.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported in our consolidated financial statements and the accompanying notes. Despite our intention to establish accurate estimates and reasonable assumptions, actual results could differ materially from such estimates and assumptions.

Recent Accounting Standards

In January 2017, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, which eliminates the second step of the previous two-step quantitative test of goodwill impairment. Under the new guidance, the quantitative test consists of a single step in which the carrying amount of the reporting unit is compared to its fair value. An impairment charge would be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the amount of the impairment would be limited to the total amount of goodwill allocated to the reporting unit. The guidance does not affect the existing option to perform the qualitative assessment for a reporting unit to determine whether the quantitative impairment test is necessary. The new guidance will be effective for smaller reporting companies for fiscal years beginning after December 15, 2022. The Company adopted this guidance on January 1, 2023 and it did not have a material impact on the Company’s consolidated financial statements.

Total revenue	$	1,394	$	2,392	$	3,331	$	5,931

Services Revenue

Project revenue consists of amounts recognized under contracts with customers for the development, construction and delivery of commercial-scale concentrated solar energy facilities. The Company’s recognized project revenue is associated with a commercial-scale demonstration agreement (“CSDA”) executed with Woodside Energy (USA) Inc. (“Woodside”) in March 2022.

Engineering services revenue consists of amounts recognized under contracts with customers for the provision of engineering, R&D, or other similar services in our field of expertise. Engineering service contracts typically span several years and we recognize revenue over time as customers receive and consume the benefit of such services.

Revenue recognized during the three and six months ended June 30, 2023 and 2022 includes non-governmental customers in the United States (“U.S.”) and Europe.

Grant Revenue

The Company’s grant revenue is primarily related to the Company’s award from the U.S. Department of Energy (the “DOE Award”) related to costs incurred during such periods that are reimbursable under the DOE Award.

Provision for Contract Losses

During the three and six months ended June 30, 2023, we recognized a total provision for contract losses of $20 thousand and $0.4 million, respectively, associated with our operations in Germany. During the three and six months ended June 30, 2023, we amortized $0.9 million and $1.3 million, respectively, of the previously recognized contract loss provisions as a reduction to cost of services revenue incurred during the three and six months ended June 30, 2023 based on percentages of completion.

During the six months ended June 30, 2022, we recognized a total provision for contract losses of $33.7 million driven primarily by the CSDA, of which we amortized $3.2 million as a reduction to cost of sales incurred during 2022. No provision for contract losses was recognized during the three months ended June 30, 2022.

Performance Obligations

Revenue recognized under contracts with customers relates solely to the performance obligations satisfied during the six months ended June 30, 2023 with no revenue recognized from performance obligations satisfied in prior periods. As of June 30, 2023, we had approximately $37.0 million of transaction prices allocated to remaining performance obligations from our customer contracts, we expect to recognize approximately 43% as revenue over the next 12 months and the remainder to be recognized thereafter through 2026.

Warrants

Note 3—Warrants

Public Warrants and Private Warrants

The Company’s warrant liabilities as of June 30, 2023 include public warrants (the “Public Warrants”) and private placement warrants (the “Private Warrants,” and together with the Public Warrants, the “Public and Private Warrants”). The Public Warrants and Private Warrants permit warrant holders to purchase in the aggregate approximately 8.3 million shares and approximately 0.2 million shares, respectively, of the Company’s common stock at an exercise price of $11.50 per share. The Public and Private Warrants became exercisable on March 18, 2022 and expire on December 30, 2026, or earlier upon redemption or liquidation. The Public and Private Warrants are recorded as liabilities on the consolidated balance sheets and measured at fair value at each reporting date, with the change in fair value reported in gain (loss) on warrant remeasurement on the consolidated statements of operations.

Project Warrants

In connection with the concurrent execution of the CSDA with Woodside in March 2022, the Company issued warrants permitting Woodside to purchase approximately 0.9 million shares of the Company’s common stock at an exercise price of $0.01 per share (the “Project Warrants”). The Project Warrants expire upon the earlier of a change in control of the Company or March 28, 2027 and vest pro rata with certain payments required to be made by the customer under the CSDA. The fair value of the Project Warrants upon issuance was $4.96 per warrant based on the closing price of the Company’s common stock on March 28, 2022, less the exercise price. The Project Warrants are recorded as equity on the consolidated balance sheets.

During the three and six months ended June 30, 2023, approximately 0.1 million and 0.2 million, respectively, of Project Warrants vested with a value of $63 thousand and $0.1 million, respectively, which was recognized as additional paid-in capital. During the three and six months ended June 30, 2022, approximately 0.2 million of Project Warrants vested with a value of $89 thousand and $0.4 million, respectively, which was recognized as additional paid-in capital. From the issuance date of the Project Warrants on March 28, 2022 to June 30, 2023, a total of approximately 0.5 million of Project Warrants vested with a total value of $0.8 million, which was recognized as additional paid-in capital.

Collaboration Warrants

In connection with the concurrent execution of a collaboration agreement (the “Collaboration Agreement”) with Woodside in March 2022, the Company issued warrants permitting Woodside to purchase approximately 3.6 million shares of the Company’s common stock at an exercise price of $0.01 per share (the “Collaboration Warrants”). Under the Collaboration Agreement, Woodside will assist us in defining product offerings that use our modular technology for potential customers in Australia. The Collaboration Warrants expire upon the earlier of a change in control of the Company or March 28, 2027. Of these warrants, (i) approximately 1.8 million warrants vested immediately upon execution of the Collaboration Agreement and (ii) approximately 1.8 million warrants will vest based on certain specified performance goals under the Collaboration Agreement. The fair value of the Collaboration Warrants upon issuance was $4.96 per warrant based on the closing price of the Company’s common stock on March 28, 2022, less the exercise price.

The Collaboration Warrants are recorded as equity on the consolidated balance sheets and the related expense is being recognized ratably as selling, general and administrative (“SG&A”) expense over the estimated service period. As of June 30, 2023, the Company has a prepaid expense of $6.3 million for the Collaboration Warrants, of which $2.0 million was classified as current and $4.3 million was classified as long-term. The Company recognized SG&A expense related to the vesting of the Collaboration Warrants of $0.5 million and $0.6 million during the three months ended June 30, 2023 and 2022, respectively, and of $1.0 million and $0.6 million during the six months ended June 30, 2023 and 2022, respectively. As of June 30, 2023, the remaining estimated period is approximately 3.2 years.

Vendor Warrants

On April 19, 2022, the Company issued warrants to purchase approximately 0.1 million shares of the Company’s common stock, at an exercise price of $0.01 per share (“Vendor Warrants”), to a vendor as compensation for services to be performed by the vendor. The Vendor Warrants vest in twelve equal monthly installments. The Vendor Warrants are recorded as equity on the consolidated balance sheets and had a fair value upon issuance of $0.3 million, to be recognized ratably over one year as SG&A expense. During the six months ended June 30, 2023 and 2022, the Company recognized $0.1 million and $0.1 million, respectively, of share-based compensation expense, included in SG&A, related to the portion of the Vendor Warrants that vested during the period. As of April 2023, the Vendor Warrants are fully vested.

________________

(1)Included in warrant liabilities on the consolidated balance sheets.

(2)Included in other long-term liabilities on the consolidated balance sheets.

Private Warrants. The fair value of the Private Warrants approximates the fair value of the Public Warrants due to the existence of similar redemption provisions. As a result, the Company has determined that the fair value of the Private Warrants at a specific date would be similar to that of the Public Warrants, and thus their fair value is determined by using the closing price of the Public Warrants, which was $0.05 as of June 30, 2023.

Contingent Consideration. The contingent consideration was measured at fair value using a probability-weighted cash-flow method. The key inputs used in the valuation for the contingent consideration as of June 30, 2023 included the timing and probability of payment.

The following table summarizes the activities of our Level 3 fair value measurement:

Note 8—Goodwill and Intangible Assets

Goodwill

The Company had goodwill related to the acquisition of HelioHeat GmbH, a private limited liability company in Germany engaged in the development, planning and construction of renewable energy systems and components, including a novel solar receiver.

During the first quarter of 2023, the Company performed a goodwill impairment assessment driven by the sustained decline in the Company’s market capitalization below the Company’s carrying value. Management concluded that it is more likely than not that the fair value of our reporting unit was less than its carrying amount as of March 31, 2023. As a result, the Company fully impaired goodwill and recognized a $1.0 million charge during the three months ended March 31, 2023. The Company had no impairments of goodwill recognized during the six months ended June 30, 2022.

The changes in the carrying amount of goodwill are as follows:

Stockholders Rights Plan

On April 16, 2023, the Company’s Board of Directors (the “Board”) declared a dividend of one preferred share purchase right (“Right”) for each outstanding share of the Company’s common stock to the stockholders of record as of the close of business on April 28, 2023, and adopted a limited duration stockholder rights plan, effective immediately, as set forth in the Rights Agreement, dated as of April 16, 2023 (the “Rights Agreement”), by and between the Company and Continental Stock Transfer & Trust Company, as rights agent. The Rights will be exercisable only if a person or group (an “acquiring person”) acquires or launches a tender or exchange offer to acquire beneficial ownership (which includes certain synthetic equity interests) of 12.5% or more of the Company’s outstanding common stock (20% for certain passive institutional investors as described in the Rights Agreement). Once the Rights become exercisable, each Right will entitle its holder (other than the acquiring person, whose rights will become void) to purchase for $3.50, subject to adjustment, additional shares of our common stock having a market value of twice such exercise price. In addition, the Rights Agreement has customary flip-over and exchange features. The Rights will expire on April 17, 2024 unless the rights are earlier redeemed or exchanged by the Company. The Rights Agreement will reduce the likelihood that any entity, person or group gains control of Heliogen through open market accumulation without paying all stockholders an appropriate control premium or without providing our Board sufficient time to make informed judgments and take actions that are in the best interests of all stockholders.

Income Taxes

Income Tax Disclosure [Abstract]

Income Taxes

Note 13—Income Taxes

We calculate our quarterly tax provision pursuant to the guidelines in Accounting Standards Codification (“ASC”) 740, Income Taxes. ASC 740 requires companies to estimate the annual effective tax rate for current year ordinary income. In calculating the effective tax rate, permanent differences between financial reporting and taxable income are factored into the calculation, and temporary differences are not. The estimated annual effective tax rate represents the Company’s estimate of the tax provision in relation to the best estimate of pre-tax ordinary income or loss. The estimated annual effective tax rate is then applied to year-to-date ordinary income or loss to calculate the year-to-date interim tax provision. The relationship between our income tax provision or benefit and our pre-tax book income or loss can vary significantly from period to period considering, among other factors, the overall level of pre-tax book income or loss and changes in the blend of jurisdictional income or loss that is taxed at different rates and changes in valuation allowances. The income tax provision was $2 thousand for the three and six months ended June 30, 2023, respectively. The income tax benefit of $0.1 million and $0.7 million for the three and six months ended June 30, 2022, respectively, is primarily attributable to our operations in Germany. Any income tax benefit associated with the pre-tax loss for the three and six months ended June 30, 2023 and 2022, resulting primarily from the U.S. jurisdiction, is offset by a full valuation allowance.

In assessing the realizability of deferred tax assets, we consider whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Based upon the analysis of federal and state deferred tax balances, future tax projections and availability of taxable income in the carryback period, we recorded a full valuation allowance against the federal and state deferred tax assets for the six months ended June 30, 2023 and the year ended December 31, 2022.

The Company is subject to the provisions of ASC Subtopic 740-10, Accounting for Uncertainty in Income Taxes. This standard defines the threshold for recognizing the benefits of tax return positions in the financial statements as more-likely-than-not to be sustained by the relevant taxing authority and requires measurement of a tax position meeting the more-likely-than-not criterion, based on the largest benefit that is more than 50% likely to be realized. If upon performance of an assessment pursuant to this subtopic, management determines that uncertainties in tax positions exist that do not meet the minimum threshold for recognition of the related tax benefit, a liability is recorded in the consolidated financial statements. The Company recognizes interest and penalties, if any, related to unrecognized tax benefits as a component of income tax expense. We do not have material unrecognized tax benefits for uncertain tax positions.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information. Accordingly, these unaudited consolidated financial statements do not include all information or notes required by GAAP for annual financial statements. In the opinion of management, the unaudited consolidated financial statements have been prepared on the same basis as the annual financial statements and include all adjustments, consisting of only normal recurring adjustments, necessary for fair statement.

The results reported in these unaudited consolidated financial statements are not necessarily indicative of the results that may be reported for the entire year. These unaudited 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, 2022, filed with the Securities and Exchange Commission on March 29, 2023.

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported in our consolidated financial statements and the accompanying notes. Despite our intention to establish accurate estimates and reasonable assumptions, actual results could differ materially from such estimates and assumptions.

Recent Accounting Standards

Recent Accounting Standards

In January 2017, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, which eliminates the second step of the previous two-step quantitative test of goodwill impairment. Under the new guidance, the quantitative test consists of a single step in which the carrying amount of the reporting unit is compared to its fair value. An impairment charge would be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the amount of the impairment would be limited to the total amount of goodwill allocated to the reporting unit. The guidance does not affect the existing option to perform the qualitative assessment for a reporting unit to determine whether the quantitative impairment test is necessary. The new guidance will be effective for smaller reporting companies for fiscal years beginning after December 15, 2022. The Company adopted this guidance on January 1, 2023 and it did not have a material impact on the Company’s consolidated financial statements.
