This prospectus also relates to the offer and resale from time to time by the selling securityholders (including their transferees, donees, pledgees and other successors-in-interest) named in this prospectus (the “Selling Securityholders”) of up to:

​

​

​

Table of Contents

We are registering the offer and sale and/or resale of these securities to satisfy certain registration obligations we have and certain registration rights we have granted. The Selling Securityholders may offer all or part of the Resale Securities for resale from time to time through public or private transactions, at either prevailing market prices or at privately negotiated prices. The Resale Securities are being registered to permit the Selling Securityholders to sell Resale Securities from time to time, in amounts, at prices and on terms determined at the time of offering. The Selling Securityholders may sell the Resale Securities through ordinary brokerage transactions, in underwritten offerings, directly to market makers of our securities or through any other means described in the section entitled “Plan of Distribution” herein. In connection with any sales of Resale Securities offered hereunder, the Selling Securityholders, any underwriters, agents, brokers or dealers participating in such sales may be deemed to be “underwriters” within the meaning of the Securities Act, or the Exchange Act. We are registering the Resale Securities for resale by the Selling Securityholders, or their donees, pledgees, transferees, distributees or other successors-in-interest selling our Ordinary Shares or Vast Warrants or interests in our Ordinary Shares or Vast Warrants received after the date of this prospectus from the Selling Securityholders as a gift, pledge, partnership distribution or other transfer.

Certain Resale Securities held by the Selling Securityholders party to the Shareholder and Registration Rights Agreement are subject to contractual lock-up restrictions that prohibit them from selling such securities at this time, subject to certain exceptions. See the section of this prospectus entitled “Description of Securities.”

Table of Contents

Some of the Ordinary Shares being registered for resale were acquired by the Selling Securityholders for prices considerably below the current market price of the Ordinary Shares. Even though the current market price ($3.41 closing price on April 19, 2024) is significantly below the $10.00 per unit price offered in the NETC IPO, certain Selling Securityholders may have an incentive to sell because they have purchased their Ordinary Shares or Warrants at effective prices significantly lower than our public investors or the current trading price of the Ordinary Shares or Warrants and may profit significantly so even under circumstances in which our public shareholders or certain other Selling Securityholders would experience losses in connection with their investment. For additional information, see “Risk Factors — Risks Relating to Ownership of Our Securities —  Certain of the Selling Securityholders acquired their Ordinary Shares at a price that is less than the market price of the Ordinary Shares as of the date of this prospectus, may earn a positive rate of return even if the price of the Ordinary Shares declines and may be willing to sell their Ordinary Shares at a price less than shareholders that acquired Ordinary Shares in the public market.”

On December 18, 2023 (the “Closing Date”), we consummated the business combination pursuant to the Business Combination Agreement, dated as of February 14, 2023, as amended on October 19, 2023 (the “Business Combination Agreement,” and the transactions contemplated thereby, the “Business Combination”), by and among the Company, NETC, Neptune Merger Sub, Inc., a Delaware corporation and wholly owned direct subsidiary of the Company (“Merger Sub”), the NETC Sponsor (solely with respect to Sections 5.20, 7.10(a) and 7.16 thereto), and Nabors Industries Ltd. (“Nabors”) (solely with respect to Sections 7.8(d) and 7.18 thereto), pursuant to which, among other things and subject to the terms and conditions contained therein, Merger Sub merged with and into NETC (the “Merger”), with NETC continuing as the surviving corporation and a wholly owned direct subsidiary of the Company (the “Surviving Corporation”).

Immediately prior to the effective time of the Merger (the “Effective Time”):

At the Effective Time, by virtue of the Merger and without any action on the part of the Company, NETC, Merger Sub or any of the holders of any of their securities, the following events took place simultaneously:

​

Table of Contents

NETC Class B Common Stock issued and outstanding and not held by the NETC Sponsor or its transferees immediately prior to the Effective Time was exchanged for one Ordinary Share, and (iv) each share of NETC Class F Common Stock issued and outstanding and not held by the NETC Sponsor or its transferees immediately prior to the Effective Time was exchanged for one Ordinary Share, in each case, after giving effect to the Split Adjustment (collectively, the “Per Share Merger Consideration”) and thereafter, each share of NETC Class A Common Stock, NETC Class F Common Stock and NETC Class B Common Stock was automatically cancelled and ceased to exist and each holder of NETC Class A Common Stock, NETC Class F Common Stock and NETC Class B Common Stock ceased to have any rights with respect thereto except the right to receive the Per Share Merger Consideration (other than pursuant to and in accordance with that certain letter agreement, dated as of February 14, 2023, by and among NETC, the NETC Sponsor, Vast, Nabors Lux and NETC’s independent directors (as amended on October 19, 2023, the “Support Agreement”);

Each share of NETC Class A Common Stock issued and outstanding immediately prior to the Effective Time with respect to which a NETC stockholder validly exercised its redemption rights (the “Redemption Shares”) was not entitled to receive the Per Share Merger Consideration and was converted immediately prior to the Effective Time into the right to receive from NETC, in cash, an amount per share calculated in accordance with such stockholder’s redemption rights.

Certain other related agreements were entered into in connection with the Business Combination, including the Notes Subscription Agreements, the Equity Subscription Agreements, the Canberra Subscription Agreement, the Nabors Backstop Agreement, the Shareholder and Registration Rights Agreement, the Support Agreement, the Noteholder Support and Loan Termination Agreement, the MEP Deed, MEP De-SPAC Side Deed, the Services Agreement, the Development Agreement, the October Notes Subscription Agreement, the EDF Note Purchase Agreement, the JDA, the Parent Company Guarantee, the Nabors Backstop Agreement Amendment and the Nabors Backstop Loan each as defined and described elsewhere in this prospectus.

At the Effective Time, Vast issued:

​

Table of Contents

On January 12, 2024, Vast issued an additional 681,620 Ordinary Shares to Nabors Lux pursuant to the Nabors Backstop Agreement.

The Ordinary Shares being offered for resale by the Selling Securityholders pursuant to this prospectus represent approximately 72.2% of our total issued and outstanding Ordinary Shares on a fully diluted basis (assuming and after giving effect to the issuance of 27,529,987 Ordinary Shares upon exercise of all outstanding Warrants, 2,799,999 Earnout Shares issuable upon the occurrence of all Triggering Events, and 2,400,000 Earnback Shares issuable upon the occurrence of all Triggering Events, the conversion of the EDF Note and the Warrants being offered for resale pursuant to this prospectus represent approximately 46.7% of our current total outstanding Warrants. Upon expiration of the contractual lock-up restrictions mentioned above and described in the section entitled “Certain Relationships and Related Persons Transactions,” the Selling Securityholders, including AgCentral (who holds approximately 34.8% of our total issued and outstanding Ordinary Shares on a fully diluted basis and has voting power over approximately 38.9% of our total issued and outstanding Ordinary Shares on a fully diluted basis) and Nabors Lux (who is a beneficial owner of approximately 18.7% of our total issued and outstanding Ordinary Shares on a fully diluted basis), will be able to sell all of their Resale Securities registered for resale hereunder for so long as this registration statement of which this prospectus forms a part is available for use. Given the substantial number of Resale Securities being registered for potential resale by the Selling Securityholders pursuant to the registration statement of which this prospectus forms a part, the sale of such Resale Securities by the Selling Securityholders, or the perception in the market that the Selling Securityholders may or intend to sell all or a significant portion of such Resale Securities, could increase the volatility of the market price of our Ordinary Shares or Public Warrants or result in a significant decline in the public trading price of our Ordinary Shares or Public Warrants. The Selling Securityholders acquired, or have the option to acquire, the Ordinary Shares covered by this prospectus at prices ranging from less than $0.01 per share to $11.50 per share. By comparison, the offering price to public stockholders in the NETC IPO was $10.00 per unit, each of which consisted of one share of NETC Class A Common Stock and one-half of one redeemable NETC Public Warrant. Consequently, certain Selling Securityholders may realize a positive rate of return on the sale of their Resale Securities covered by this prospectus even though the market price of Ordinary Shares is currently $3.41 (based on the closing price on April 19, 2024) which is significantly below the $10.00 per unit price offered in the NETC IPO and public shareholders and/or warrantholders may experience a negative rate of return on their investment. The contractual lock-up restrictions are subject to certain exceptions, including an exception that permits sales of Resale Securities during the lock-up period to satisfy tax obligations of Selling Securityholders.

We will not receive any proceeds from the sale of the Resale Securities by the Selling Securityholders. We will receive the proceeds upon exercise of Vast Warrants to the extent such Vast Warrants are exercised for cash. Assuming the exercise of all outstanding Vast Warrants for cash, we would receive aggregate proceeds of approximately $316.6 million. However, we will only receive such proceeds if all Vast Warrant holders fully exercise their Vast Warrants for cash. The exercise price of the Vast Warrants is $11.50 per share. We believe that the likelihood that holders determine to exercise their Vast Warrants, and therefore the amount of cash proceeds that we would receive, is dependent upon the market price of our Ordinary Shares. If the market price for our Ordinary Shares is less than the exercise price of the Vast Warrants (on a per share basis), we believe that holders will be very unlikely to exercise any of their Vast Warrants, and accordingly, we will not receive any such proceeds. There is no assurance that the Vast Warrants will be “in the money” prior to their expiration or that the holders will exercise their Vast Warrants. Vast Warrant holders have the option to exercise their Vast Warrants on a cashless basis in accordance with the Vast Warrant Agreements. To the extent that any Vast Warrants are exercised on a cashless basis, the amount of cash we would receive from the exercise of Vast Warrants will decrease.

Table of Contents

We may amend or supplement this prospectus from time to time by filing amendments or supplements as required. You should read this entire prospectus and any amendments or supplements carefully before you make your investment decision. Our Ordinary Shares and Public Warrants are listed on The Nasdaq Stock Market LLC, (“Nasdaq”) under the trading symbols “VSTE” and “VSTEW,” respectively. On April 19, 2024, the closing prices for our Ordinary Shares and Public Warrants on Nasdaq were $3.41 per share and $0.17 per warrant, respectively.

We are an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012 and are therefore eligible to take advantage of certain reduced reporting requirements applicable to other public companies.

We are also a “foreign private issuer” as defined in the Exchange Act and are exempt from certain rules under the Exchange Act that impose certain disclosure obligations and procedural requirements for proxy solicitations under Section 14 of the Exchange Act. In addition, our officers, directors and principal shareholders are exempt from the reporting and “short-swing” profit recovery provisions under Section 16 of the Exchange Act with respect to their purchases and sales of Ordinary Shares. Moreover, we are not required to file periodic reports and financial statements with the SEC as frequently or as promptly as U.S. companies whose securities are registered under the Exchange Act. See “Risk Factors--Risks Related to Ownership of Our Securities--As a “foreign private issuer” under the rules and regulations of the SEC, we are permitted to, and will, file less or different information with the SEC than a company incorporated in the United States or otherwise not filing as a “foreign private issuer,” and will follow certain home country corporate governance practices in lieu of certain Nasdaq requirements applicable to U.S. issuers. Accordingly, there will be less publicly available information concerning the Company than there is for issuers that are not foreign private issuers.”

Investing in our securities involves a high degree of risk. See “Risk Factors” beginning on page 20 of this prospectus for a discussion of information that should be considered in connection with an investment in our securities.

Neither the SEC nor any other regulatory body has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

PRESENTATION OF FINANCIAL INFORMATION

This prospectus contains:

Unless indicated otherwise, financial data presented in this prospectus has been taken from the audited and unaudited consolidated financial statements of Vast, as applicable, included in this prospectus. Where information is identified as “unaudited,” it has not been derived from financial statements that have been subject to an audit. Unless otherwise indicated, financial information of Vast and SiliconAurora has been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”). Due to rounding, certain numbers presented in this prospectus may not add up precisely to the totals provided and percentages may not precisely reflect the absolute figures.

As presented herein, Vast publishes its consolidated financial statements in U.S. dollars. SiliconAurora publishes its financial statements in Australian dollars. In this prospectus, unless otherwise specified, all monetary amounts are in U.S. dollars, all references to “$,” “US$,” “USD” and “dollars” mean U.S. dollars and all references to “A$” and “AUD” mean Australian dollars.

EXCHANGE RATES

Vast presents its consolidated financial statements in U.S. dollars. The determination of the functional currency of each group company is based on the primary currency in which the group company operates. Our functional currency is the Australian dollar. The functional currency of our subsidiaries will generally be the local currency.

The translation of foreign currencies into U.S. dollars is performed for assets and liabilities at the end of each reporting period based on the then current exchange rates. Revenue and expense transactions are translated into U.S. dollars using exchange rates that approximate those prevailing at the dates of the transactions, including the use of average rates where appropriate. For revenue and expense accounts, an average monthly foreign currency rate is applied. Adjustments resulting from translating foreign functional currency financial statements into U.S. dollars will be recorded as part of a separate component of shareholders’ deficit and reported in our Consolidated Statements of Comprehensive Loss. Foreign currency transaction gains and losses will be included in other income (expense), net for the period.

NON-IFRS FINANCIAL MEASURES

This prospectus includes certain financial measures that have not been prepared in accordance with IFRS and are not recognized measures of financial performance or liquidity under IFRS. In addition to the financial information contained in this prospectus presented in accordance with IFRS, certain “non-IFRS financial measures” (as defined in Regulation G or Item 10(e) of Regulation S-K under the Securities Act) have been included in this prospectus. These non-IFRS measures should not be considered as alternatives to operating income, cash flows from operating activities or any other performance measures derived in accordance with IFRS. These measures have important limitations as analytical tools, and you should not consider them in isolation or as a substitute for analysis of our results as reported under IFRS.

PROSPECTUS SUMMARY

Overview

Vast is an Australian public company limited by shares incorporated on March 27, 2009. We are a leading renewable energy company that has developed concentrated solar power (CSP) systems to generate, store and dispatch carbon free, utility-scale electricity and industrial heat, and to enable the production of green fuels. Our unique approach to CSP utilizes a proprietary, modular sodium loop to efficiently capture and convert solar heat into these end products. Our vision is to provide continuous carbon-free energy globally by deploying our CSP technology and complementary technologies (e.g., intermittent solar PV and wind) to deliver renewable and dispatchable electricity, heat and storage on a continuous basis. We believe our CSP technology is capable of providing competitive, dispatchable and carbon-free power for on- and off-grid power generation applications, energy storage, process heat, and has the potential to unlock green fuels production.

Our executive offices are located at Suite 7.02, 124 Walker Street, North Sydney, NSW 2060, Australia, and our telephone number is +61 2 4072 2889.

Structure of Vast

The following diagram depicts the simplified organizational structure of the Company and its subsidiaries:

Status as Emerging Growth Company

We are an “emerging growth company” as defined in the JOBS Act. The Company may take advantage of exemptions from various reporting requirements that are applicable to most other public companies, including, but not limited to, an exemption from the provisions of Section 404(b) of the Sarbanes-Oxley Act requiring that the Company’s independent registered public accounting firm provide an attestation report on the effectiveness of its internal control over financial reporting and reduced disclosure obligations regarding executive compensation. If some investors find the Company less attractive as a result, there may be a less active trading market for the Company’s securities and the prices of the Company’s securities may be more volatile.

Foreign Private Issuer

Vast is a “foreign private issuer” as defined in the Exchange Act. As a “foreign private issuer,” we are exempt from certain rules under the Exchange Act, including certain disclosure and procedural requirements applicable to proxy solicitations under Section 14 of the Exchange Act, our board, officers and principal shareholders are exempt from the reporting and “short-swing” profit recovery provisions of Section 16 of the Exchange Act with respect to their purchases and sales of our Ordinary Shares, and we are not required to file periodic reports and financial statements with the SEC as frequently or as promptly as companies whose securities are registered under the Exchange Act but are not foreign private issuers. See “Risk Factors--Risks Related to Ownership of Our Securities--As a “foreign private issuer” under the rules and regulations of the SEC, we are permitted to, and will, file less or

Table of Contents

different information with the SEC than a company incorporated in the United States or otherwise not filing as a “foreign private issuer,” and will follow certain home country corporate governance practices in lieu of certain Nasdaq requirements applicable to U.S. issuers. Accordingly, there will be less publicly available information concerning the Company than there is for issuers that are not foreign private issuers.” Foreign private issuers are also not required to comply with Regulation Fair Disclosure (“Regulation FD”), which restricts the selective disclosure of material non-public information. Accordingly, there may be less publicly available information concerning the Company than there is for companies whose securities are registered under the Exchange Act but are not foreign private issuers, and such information may not be provided as promptly as it is provided by such companies. As a “foreign private issuer,” the Company is also permitted to follow certain home country corporate governance practices in lieu of the requirements of the Nasdaq Listing Rules pursuant to Nasdaq Rule 5615(a)(3), which provides for such exemption to compliance with the Nasdaq Rule 5600 Series and certain other Nasdaq Listing Rules. We rely on the exemptions available to foreign private issuers listed in the section entitled “Management—Foreign Private Issuer Status,” and we may rely on additional exemptions in the future.

Risk Factors (Page 20)

Our business is subject to numerous risks and uncertainties, including those highlighted in the section entitled “Risk Factors” immediately following this prospectus summary, that represent challenges that we face in connection with the successful implementation of our strategy and the growth of our business. In particular, the following considerations, among others, may offset our competitive strengths or have a negative effect on our business strategy, which could cause a decline in the price of our securities and result in a loss of all or a portion of your investment.

Additional risks not presently known to us or that we currently deem immaterial may also impair our business operations. The risk factors described below are not necessarily exhaustive and you are encouraged to perform your own investigation with respect to the business of the Company. Unless the context otherwise requires, references in this “Risk Factors” to “we”, “us”, “our”, and “the Company” refer to Vast and its consolidated subsidiaries.

Risks Relating to Our Target Markets

General Risks Affecting Our Target Markets

If the demand for our CSP technology does not grow as anticipated, it will negatively impact our revenue and harm our overall performance.

We believe, and our growth plans assume, that the market for concentrated solar energy solutions will continue to grow, that we will increase our penetration of this market and that our revenues from selling into this market will increase over time. If our expectations as to the size of this market or our ability to sell our products and services in this market are not correct (whether due to unforeseen government intervention or otherwise), our revenues will suffer, and our business will be harmed.

Certain estimates of market opportunity and forecasts of market growth may prove to be inaccurate.

Estimates of the total addressable market for applications of our CSP technology are included in this prospectus and from time to time, we make statements with estimates of the addressable market for our solutions and the concentrated solar energy market in general. Market opportunity estimates and growth forecasts, whether obtained from third-party sources or developed internally, are subject to significant uncertainty and are based on assumptions and estimates that may prove to be inaccurate. The estimates and forecasts relating to the size and expected growth of the target market, market demand and adoption, capacity to address this demand and pricing may also prove to be inaccurate. In particular, estimates regarding the current and projected market opportunity are difficult to predict. The estimated addressable market may not materialize for many years, if ever, and even if the markets meet the size estimates and growth forecasts, our business could fail to grow at similar rates.

Expanding our operations beyond Australia is a planned avenue for growth, but this strategy comes with additional risks that may not be encountered domestically. These risks could have a material adverse effect on our business and financial performance.

As part of our business strategy, we intend to continue to consider the expansion of our addressable market by pursuing opportunities to provide our solutions in markets outside of Australia, and we expect to generate a portion of our revenues from operations outside of Australia in the future. Operations in international markets may require us to respond to new anticipated and unanticipated regulatory, marketing, sales and other challenges. These efforts may be time-consuming and costly, and there can be no assurance that we will be successful in responding to these and other challenges we may face as we enter and attempt to expand in international markets, including:

20

Table of Contents

Our future international operations will also be subject to general geopolitical risks, such as political, social and economic instability, pandemics such as COVID-19 pandemic, war, including the war in Ukraine, incidents of terrorism, changes in diplomatic and trade relations, or responses to such events. One or more of these factors could adversely affect any of our international operations, disrupt supply chains and result in lower revenue and/or greater operating expenses than we expect, and could significantly affect our results of operations and financial condition.

Our overall success in international markets will depend, in part, on our ability to succeed in varying legal, regulatory, economic, social and political conditions. We may not be successful in developing and implementing policies and strategies that will be effective in managing these risks in each country where we do business. Our failure to manage these risks successfully could harm our international operations, reduce our international sales and increase our costs, thus adversely affecting our business, financial condition and operating results.

We operate in a highly competitive industry, where our present or future competitors may be able to compete more effectively than we do, which could have a material adverse effect on our business, revenues, growth rates, and market share.

The markets and industries which we expect to compete in are highly competitive, with many companies of varying size and business models, many of which have their own proprietary technologies, competing for the same business as we do. Many of our competitors have longer operating histories and greater financial and other resources, larger scale manufacturing operations and lower labor and research and development costs than us and could focus their substantial financial resources to develop a competitive

21

Table of Contents

advantage. Our financial performance depends, in part, on our ability to design, develop, manufacture, assemble, test, market and support new products and technology enhancements on a timely and cost-effective basis. Our competitors may offer energy solutions at prices below cost, devote significant sales forces to compete with us or attempt to recruit our key personnel by increasing compensation, any of which could improve their competitive positions. Additionally, we expect competition to intensify in the future as existing competitors and new market entrants introduce new products into our markets. Any of these competitive factors could make it more difficult for us to attract and retain customers, increase our sales and marketing expenses, reduce profit margins, cause us to lower our prices in order to compete, and reduce our market share and revenues, any of which could have a material adverse effect on our financial condition and operating results. We can provide no assurance that we will continue to effectively compete against our current competitors or additional companies that may enter our markets.

In addition, we may also face competition based on technological developments that compete with our products and services. Our competitors may develop technology that would make our technology non-competitive or obsolete. For example, the development of a low-cost, long-duration (8+ hours) and durable electric battery might enable the dominant forms of variable renewable energy, photovoltaic systems (“PV”) and wind, to economically store energy produced when the sun is shining, and the wind is blowing for use overnight or during periods of low wind. This would limit some of the use cases for and value of our CSPv3.0 technology (“CSPv3.0”), leading to reduced demand. Additionally, Abengoa, S.A. and Sener Group, the two main developers of CSP technology, may have competitive advantages in the market should they choose to focus on CSPv.3.0 technology due to their extensive resources and operating history.

More generally, if we do not keep pace with product and technology advances and otherwise keep our product offerings competitive, there could be a material and adverse effect on our competitive position, revenue and prospects for growth. Some of our existing competitors, have, and some of our potential competitors could have, substantial competitive advantages.

Some of our expected larger competitors may have substantially broader product offerings, larger sales and marketing budgets, and more substantial resources (both financial and otherwise) relating to customer support, potential acquisition and manufacturing operations, and may be able to leverage their relationships with partners and customers based on other products to gain business in a manner that discourages potential customers from purchasing our CSP plants, including by selling at zero or negative margins or product bundling. In addition, innovative start-up companies, and larger companies that are making significant investments in research and development, may invent similar or superior technologies that compete with our technologies. Our current and potential competitors may also establish cooperative relationships among themselves or with third parties that may further enhance their resources. If we are unable to compete successfully, or if competing successfully requires us to take costly actions in response to the actions of our competitors, our business, financial condition and results of operations could be adversely affected.

Widespread success of variable renewable energy generation technologies, including PV and wind, limit the use cases and addressable market for our technology, which may have a material adverse effect on our prospects, financial condition and results of operation.

There are already substantial variable renewable energy generation plants successfully operating in Australia and elsewhere. PV electricity generation has been heavily deployed in Australia on both residential and utility scales. As the prices for PV panels and the other equipment required for PV electricity generation have continued to come down, PV has become one of the cheapest ways to generate electricity in Australia during daylight hours and while the sun is shining. Similarly, dozens of utility-scale wind farms have been developed in Australia and represent one of the cheapest ways to generate electricity in Australia.

In general, a CSP plant in Australia and elsewhere would be unable to compete successfully with the low price of energy offered by PV and wind installations. As a result, we do not intend to compete, and expect we would be unable to compete successfully, with PV and wind in the delivery of on-grid energy during daylight hours. Investors should be aware that this limits the commercial use cases for our CSP plants largely to overnight applications and certain off-grid applications, reducing the total share of daily electricity requirements that our CSP offerings can profitably contribute. In addition, as construction of CSP plants requires significant upfront fixed costs, limiting the time periods over which a CSP plant dispatches energy to certain hours of the day would reduce the total dispatched energy over which the fixed costs are amortized, increasing the cost of energy and increasing the time required to amortize fixed costs. These limitations may reduce demand for our offerings, limit our growth and reduce revenue, which may have a material adverse effect on our prospects, financial condition and results of operation.

Table of Contents

Electricity

Existing electric utility industry regulations, and changes to regulations, may present technical, regulatory and economic barriers to the purchase and use of solar energy offerings that may significantly reduce demand for our solar energy offerings.

Government regulations and policies in Australia and elsewhere concerning the electric utility industry, and internal policies and regulations promulgated by electric utilities, heavily influence the market for electricity generation products and services. These regulations and policies often relate to electricity pricing and the interconnection of customer-owned electricity generation with the broader electrical grid.

In Australia and elsewhere, governments and utilities continuously modify these regulations and policies. These regulations and policies could deter customers from purchasing renewable energy, including solar energy systems. This could result in a significant reduction in the potential demand for our solar energy systems. For example, utilities commonly charge fees to larger, industrial customers for disconnecting from the electric grid or for having the capacity to use power from the electric grid for back-up purposes. These fees could increase our customers’ cost to use our systems and make them less desirable, thereby harming our business, prospects, financial condition and results of operations. In addition, in many regions, the price of electricity from the electric grid varies relative to peak hours and electricity generated by solar energy systems is more expensive than the lower average price of electricity from the electric grid. Modifications to the utilities’ pricing policies or rate design would require us to lower the price of our solar energy systems to compete with the price of electricity from the electric grid. In addition, government support for other fuels in the off-grid energy market in conjunction with ramping issues for VS1 would require lowering prices of our technology output.

In addition, any changes to government or internal utility regulations and policies that favor existing electric utilities could reduce our competitiveness and cause a significant reduction in demand for our products and services.

A material reduction in the retail price of traditional utility-generated electricity or electricity from other sources could harm our business, financial condition, results of operations and prospects.

We believe that a significant motivation for governments and private companies to invest in solar energy is their desire to reduce electricity costs as compared to costs charged by the traditional utilities. A reduction in utility electricity prices would make our CSP systems less economically attractive.

The decision to invest in CSP or CST may also be affected by the cost of other renewable energy sources. Decreases in the retail prices of electricity from the traditional utilities or from other renewable energy sources would harm our ability to offer competitive pricing and could harm our business. The price of electricity from traditional utilities or from other renewable energy sources could decrease as a result of:

23

Table of Contents

If the retail price of energy available from traditional utilities or other renewable energy sources were to decrease due to any of these reasons, or other reasons, we would be at a competitive disadvantage, we may be unable to attract new customers and our growth would be limited.

Commercial deployment of new power generation technology, such as CSPv3.0, is difficult because incumbent technologies benefit from proven track records, installed bases and lower prices.

Commercial deployment of new power generation technology, such as CSPv3.0, is difficult because it must compete against incumbent technologies that enjoy certain advantages over new technology simply because they have already been built and placed in operation. Development of generation plants, whether they are coal-fired, natural gas, PV, wind, CSPv3.0 or otherwise requires significant investments of both time and money. These are costs that are incurred independent of how much energy is ultimately produced by the plant. Once built and placed into service, there is generally a strong incentive to operate such plants for the full course of their economic life. In particular, with the costs of construction already invested, it is economically rational to operate a plant for as long as revenue for generating energy exceeds the incremental costs of generating that energy. In addition, operational generation plants are known commodities capable of delivering benefit today, which makes them more attractive than unbuilt plants using new technology that will, at best, deliver a benefit at some point in the future. As a result, even if the technology is superior, commercial deployment of new power generation technology, such as CSPv3.0, may be limited to the replacement of existing power plants as and when they reach the end of their economic lives or times at which additional capacity is required. These structural impediments may reduce demand for our offerings, delay the rate at which we can deploy our technology and limit our growth in the short and medium term, and any of these could have a material adverse effect on our prospects, financial condition and results of operation.

In addition, in a market-based system such as the Australian National Energy Market, energy generated by plants using new technology must be price competitive with energy generated by plants using incumbent technology such as coal and natural gas. In many cases, coal, natural gas and other incumbent power plants have been in operation for significant periods of time over which they have already amortized their fixed project costs of construction. As a result, such plants are now able to make a profit even if they offer energy at prices just above their marginal variable costs that are difficult or impossible for newly built plants to match. Compounding this disadvantage, the owners of incumbent generation plants are entrenched market participants who appear to respond aggressively to limit new entrants to the market and/or extract maximum fees for the provision of access to the market. We may be forced to lower our energy prices to match levels offered by incumbent plants or we may be unable to successfully compete with incumbent plants on price, at all. If we are forced to lower our energy prices, it would reduce revenue and profit margins resulting in a material adverse effect on our prospects, financial condition and results of operation. If we are unable to successfully compete with incumbent plants on price, it may reduce demand for our offerings and limit our growth which may have a material adverse effect on our prospects, financial condition and results of operation.

Industrial Process Heat

The industrial process heat market is extremely fragmented and competitive.

The industrial process heat market is extremely fragmented and competitive, consisting of a high number of small to medium-sized companies, each with generally low and uncertain demand, competing for market share. Such fragmentation may pose risks for us in that we may find it difficult to take advantage of economies of scale or to dedicate the time and effort necessary to establish and maintain relationships with a high number of customers. This may result in higher-than-expected costs as a percentage of overall project size resulting in lower than expected margins, which may in turn harm the our business and financial prospects. We expect the industrial process heat market to remain competitive for the foreseeable future, presenting us with significant challenges in our ability to achieve strong growth rates and acceptable profit margins. In addition, new and emerging technologies may significantly impact the industry in the coming years. If we are unable to meet these competitive challenges, we could lose market share to our competitors and experience an overall reduction in our profits.

Many brownfield sites may not have sufficient adjacent land to facilitate a CST/CSP project and may be located in irradiation poor regions.

Existing brownfield industrial process plants are not always concentrated sufficiently closely and may not have sufficient adjacent land to facilitate a CSP project. Heat cannot be transported from production to use for great distances. Hence, whilst the industrial process heat market may in aggregate sum up to a large number across our target geographies, they may not be sufficiently closely

concentrated to effectively reap the benefits of our CSPv3.0 technology. Further, these facilities may be located in regions with poor solar irradiation which would increase the cost of heat delivered using our technology. This could result in lower growth than expected within this market segment until such time when existing brownfield facilities shut down and new consolidated greenfield facilities are developed in regions more suitable for CSP. This could result in delayed or lost sales within this sector and may harm the business’s financial prospects.

Some segments of the industrial process heat market are sensitive to remediation liabilities that could delay or prevent the relocation of energy intensive industry to regions with favorable solar irradiation.

Some large industrial process heat users (e.g., Alumina smelters) may be subject to large remediation liabilities that prevent facilities from relocating to regions which are more suitable for CSP. This could result in the cost of heat using our technology being more expensive which could result in the customers losing their appetite for such a solution. This could translate to delayed or lost sales relative to expectations which could materially harm our finances.

Green Fuels

The green hydrogen and downstream derivative production (e.g., green methanol, green ammonia) industry is an emerging market and it may not receive widespread market acceptance.

The green hydrogen and downstream derivative production field is still a relatively nascent subset of the otherwise mature and heavily regulated industries of hydrogen and downstream derivative industry, and we cannot be sure that potential customers will accept hydrogen production broadly, or our products for hydrogen production specifically. Customers may be unwilling to adopt our solution over traditional or competing power sources for any number of reasons, including the perception that our technology is unproven, a lack of confidence in our business model, the perceived unavailability of backup service providers to operate and maintain our technology, and lack of awareness of our product or the perception of regulatory or political headwinds. Further, we cannot be sure that our relevant products will receive the technical certifications that may be necessary for those products to achieve widespread market acceptance. For example, we may not be able to secure International Air Transport Association technical certifications (such as the Sustainable Aviation Fuel technical certification) with respect to relevant green methanol products that it may develop. In addition, companies may take longer than expected to use green hydrogen over brown (or other colors of) hydrogen due to potential price differentiation. Because this is an emerging industry, the broad acceptance of our products and services for the production of green hydrogen and downstream derivative products (e.g., green methanol, green ammonia) is subject to a high level of uncertainty and risk. If the market develops more slowly than we anticipate, our business will be harmed.

Risks Relating to Our Business Lines

Risks Affecting Multiple Business Lines

We may not be able to successfully finish or operate our projects in a way that makes a profit and / or meets our customers’ requirements.

Development, installation, construction, and commissioning of CSP plants, and maintenance support of CSP plants, entail many risks, including:

25

Table of Contents

Any of these factors could give rise to construction delays and construction and other costs in excess of our expectations. This could prevent us from completing construction of our projects, cause defaults under any then-existing financing agreements or under contracts that require completion of project construction by a certain time, cause projects to be unprofitable, or otherwise impair our business, financial condition and operating results.

The failure of our suppliers to continue to deliver necessary raw materials or other components (including any specialty materials and components) required for our projects in a timely manner or at all, or our inability to obtain substitute sources of these components on a timely basis or on terms acceptable to us, could adversely affect our business.

We rely on a limited number of third-party suppliers for certain raw materials and components for our CSP technology. We are dependent on the availability of essential materials, parts and subassemblies from our suppliers and subcontractors. The most important raw materials required for our CSP systems are sodium, salt (sodium nitrate/potassium nitrate), steel, stainless steel, glass, copper, aluminum, commodity electrical & electronics components, ceramics & ceramic fibers, thermal insulation materials, bauxite particles and/or silica sand and concrete. Prices and availability of these raw materials are subject to substantial fluctuations that are beyond our control due to factors such as supply and demand trends, energy costs, transportation costs, inflation, government regulations, global trade relationships, duties and tariffs, changes in currency exchange rates, price controls, general economic conditions and other unforeseen circumstances.

Our components are produced by third-party suppliers both domestically and internationally where most raw materials are readily available and purchased by those independent contractors and suppliers in the country of manufacture. Many major equipment and systems components are procured on a single or sole-source basis. Further, we may find ourselves reliant on sourcing components from one or a smaller number of countries (for example China). If existing vendors are unable to supply the raw materials we require (whether due to international trade embargoes or otherwise), we cannot predict if we will be able to obtain alternative vendors within the time frames that we require and at a comparable cost. For example, the COVID-19 pandemic resulted in significant supply chain disruptions globally, and similar to other companies in our industry, we have observed significant commodity price inflation in recent months, in some cases by upwards of 30% to 100%. Russia’s invasion of and military attacks on Ukraine, including indirect impacts as a result of sanctions and economic disruption, has further complicated existing supply chain constraints. Shortages, price increases and/or delays in shipments of our raw materials and purchased component parts, have occurred and may continue to occur in the future which may have a material adverse effect on our results of operations if we are unable to successfully mitigate the impact, from products such as steel, glass, concrete and adhesives, which are used as components of supplies or materials utilized in our operations.

Additionally, if we fail to maintain our relationships with our suppliers or to build relationships with new suppliers, or if suppliers fail to perform or are unable to meet demand through industry consolidation, our supply chain could be disrupted.

26

Table of Contents

To the extent the processes that our suppliers use to manufacture components are proprietary, we may be unable to obtain comparable components from alternative suppliers. In addition, our suppliers could be unable or unwilling to raise capital if required to expand their production or satisfy their operating capital requirements. As a result, they could be unable to supply necessary raw materials, inventory and capital equipment which we would require to support our planned sales operations, which could in turn materially and adversely impact our sales volume, profitability, and cash flows. The failure of a supplier to supply raw materials or components in a timely manner, or to supply raw materials or components that meet our quality, quantity and cost requirements or, otherwise on commercially reasonable terms, could impair our ability to manufacture our products or could increase our cost of production. If we cannot obtain substitute materials or components on a timely basis or on acceptable terms, we could be prevented from delivering our products to our customers within required timeframes.

Any such delays could result in installation delays, cancellations, inability to retain customers, increased manufacturing costs, penalty payments or loss of revenue and market share, any of which could have a material and adverse effect on our business, financial condition and results of operations.

Failure of third parties to manufacture quality products or provide reliable services in a timely manner could cause delays in the delivery of our services and completion of our projects, which could damage our reputation, have a negative impact on our relationships with our customers and adversely affect our growth.

Our success depends on our ability to provide services and complete projects in a timely manner, which in part depends on the ability of third parties to provide us with timely and reliable products and services. In providing services and completing our projects, we rely on products that meet our design specifications and components supplied by third parties, as well as on services performed by subcontractors.

We will also rely on subcontractors to perform substantially all of the construction and installation work related to our projects; and we may need to engage subcontractors with whom we have no prior experience for our projects.

If any of our subcontractors are unable to provide products or services that meet or exceed our customers’ expectations or satisfy contractual commitments and performance requirements/specifications (for example, with respect to turbines supplied to us), our reputation, business and operating results could be harmed. In addition, if we are unable to avail ourselves of warranty and other contractual protections with providers of products and services, we may incur liability to our customers or additional costs related to the affected products and components, which could have a material adverse effect on our business, financial condition and operating results. Moreover, any delays, malfunctions, inefficiencies or interruptions in these products or services could adversely affect the quality and performance of our solutions and require considerable expense to establish alternate sources for such products and services. This could cause us to experience difficulty retaining current customers and attracting new customers, and could harm our brand, reputation and growth.

If our third-party suppliers and manufacturers do not comply with ethical business practices or with applicable laws and regulations, our reputation, business, financial condition, results of operations and prospects could be harmed.

Our reputation and our customers’ willingness to purchase our products and services depend in part on our suppliers’, manufacturers’, and customers’ compliance with ethical employment practices, such as with respect to child labor, wages and benefits, forced labor, discrimination, safe and healthy working conditions, and with all legal and regulatory requirements relating to the conduct of their businesses. We do not exercise control over our suppliers, manufacturers, and retail customers and cannot guarantee their compliance with ethical and lawful business practices. If our suppliers, manufacturers, or customers fail to comply with applicable laws, regulations, safety codes, employment practices, human rights standards, quality standards, environmental standards, production practices, or other obligations, norms, or ethical standards, our reputation and brand image could be harmed, and we could be exposed to litigation, investigations, enforcement actions, monetary liability, and additional costs that would harm our reputation, business, financial condition, results of operations and prospects.

Our business and growth strategy relies on having continued access to sodium metal used as the primary Heat Transfer Fluid (“HTF”).

The use of liquid sodium metal as the HTF from the solar receivers to the molten salt heat transfer system is the key innovation that unlocks the key benefits of our CSPv3.0 system. There is a limited number of suppliers of this product and any issues that impede

27

Table of Contents

or remove these suppliers from the market could result in an inability for our projects to be operated. If we are unable to obtain sufficient quantities of sodium at commercially acceptable prices, or at all, we may incur increased costs or be unable to construct or place our CSP plants into service, which would reduce profit margins and/or revenue and have a material adverse effect on our financial condition, results of operation and prospects.

Adverse weather conditions and natural disasters may have a negative impact on our operations. This includes but is not limited to short term phenomena such as volcanic eruptions and long-term deviations to the weather resource relative to historical periods.

We may be impacted by weather extremes, earthquakes, drought, floods, and wildfire, which may cause temporary, short-term anomalies in our operational performance in certain localized geographic regions. Delays and other weather impacts (including those associated with dust and clouds) could adversely affect our ability to meet project deadlines in generation and timeframe and may increase a project’s cost and decrease our profitability. In addition, any major reductions of actual solar radiation onto the sites of our plants compared to historical or projected solar radiation would decrease energy output which may reduce revenue and have a material adverse effect on our financial condition, results of operation and prospects.

A major safety incident which occurs on one or more of our projects during construction, commissioning and / or operations could result in harm to personnel, environment and property which could result in the creation of material liabilities, shutdown of site for extended time periods, severely tarnish the reputation of our technology and substantially reduce likelihood of winning future projects.

Construction sites and operating / energized industrial facilities are inherently dangerous and pose certain inherent health and safety risks to construction workers, employees and other visitors. Due to health and safety regulatory requirements, health and safety performance is important to the success of our activities. In 2015, we experienced a loss of sodium containment event due to poor tank design and operational practice at our JSS Demonstration Plant in Jemalong, which resulted in remediation works and design improvements. Incidents of similar or greater magnitude could potentially occur at future projects which use our technology. Any failure in health and safety performance may result in penalties for non-compliance with relevant regulatory requirements, and a failure that results in a major or significant health and safety incident is likely to be costly and could expose us to claims resulting from personal injury. Such a failure could generate significant negative publicity and have a corresponding impact on our reputation, our relationships with relevant regulatory agencies or governmental authorities, and our ability to attract customers and employees, which in turn could have a material adverse effect on our business, financial condition and operating results.

Our operations are and may become subject to further federal, state and local laws and regulations in Australia and elsewhere pertaining to environmental protection and operational safety that may require significant expenditures or result in liabilities that could have a material adverse effect on our business.

Our business is and may become subject to further various federal, state, and local environmental laws and regulations in Australia and elsewhere, including those relating to the release or discharge of regulated materials into the air, water, and soil, the generation, storage, handling, use, transportation, and disposal of hazardous materials, the protection of species or habitats, the protection of historical or cultural resources, the exposure of persons to regulated materials, and the health and safety of our employees. Certain environmental laws impose strict, and, under certain circumstances, joint and several, liability on the current and former owners and operators of properties for costs of investigation and removal or remediation of contamination and impose liability for any related damages to natural resources without regard to fault. We may be subject to third-party claims alleging property damage and/or personal injury in connection with releases of or exposure to hazardous substances at, from, or in the vicinity of our current or former properties or off-site waste disposal sites. In some jurisdictions, we may also be subject to financial responsibility or decommissioning requirements in connection with future facilities. Certain projects may be subject to environmental impact assessment processes which could increase the time it takes to develop a project and may include public input that could alter or restrict the operation of a proposed project. A violation of, liability under, or non-compliance with these laws and regulations, or any future environmental law or regulation, could have a material adverse effect on our business, financial condition, or operating results.

Increased attention to environmental, social and governance (“ESG”) matters and conservation measures may adversely impact our business.

While we may create and publish voluntary disclosures regarding ESG matters from time to time, many of the statements in those voluntary disclosures are based on hypothetical expectations and assumptions that may or may not be representative of current or

28

Table of Contents

actual risks or events or forecasts of expected risks or events, including the costs associated therewith. Such expectations and assumptions are necessarily uncertain and may be prone to error or subject to misinterpretation given the long timelines involved and the lack of an established single approach to identifying, measuring and reporting on many ESG matters. ESG matters may also impact our suppliers and customers, which may ultimately have adverse impacts on our operations.

Furthermore, public statements with respect to ESG matters are becoming increasingly subject to heightened scrutiny from public and governmental authorities related to the risk of potential “greenwashing,” i.e., misleading information or false claims overstating potential ESG benefits. Alleged claims of greenwashing against us or our suppliers or customers may lead to reputational damage or difficulties accessing capital. Additionally, we could face increasing costs as we attempt to comply with and navigate further regulatory ESG-related focus and scrutiny.

Elevated interest rates could adversely affect our business, our results of operations and our financial condition.

We require continued access to capital to develop and grow our business. Our business and operating results can be harmed by factors such as the availability, terms of and cost of capital, increases in interest rates or a reduction in credit rating. These changes could cause our cost of doing business to increase, limit our ability to pursue acquisition opportunities, reduce cash flow, and place us at a competitive disadvantage. Recent and continuing disruptions and volatility in the global capital markets may lead to a contraction in credit availability impacting our ability to finance our operations. A significant reduction in cash flows from operations or the availability of credit could materially and adversely affect our financial condition and results of operations.

Delays in the construction of our projects or significant cost overruns could present significant risks to our business and could have a material adverse effect on our business, financial condition and results of operations.

Our ability to proceed with projects under development and to complete the construction of, or capital improvements to, facilities on schedule and within budget may be adversely affected by escalating costs for materials and labor and regulatory compliance, inability to obtain or renew necessary licenses, rights-of-way, permits or other approvals on acceptable terms or on schedule, disputes involving contractors, labor organizations, land owners, governmental entities, environmental groups, native and aboriginal groups, lessors, joint venture partners and other third parties, negative publicity, interconnection issues and other factors. In addition, we are reliant on experience and resources of designers, general contractors and subcontractors, who may experience financial or other problems during the design or construction process.

If any development project or construction or capital improvement project is not completed, is delayed or is subject to cost overruns, certain associated costs may not be approved for recovery or otherwise be recoverable through regulatory mechanisms that may be available, and we could become obligated to make delay or termination payments or become obligated for other damages under contracts, could experience the loss of tax credits or tax incentives, or delayed or diminished returns, and could be required to write off all or a portion of our investment in the project. Any of these events could have a material adverse effect on our business, financial condition, results of operations and prospects.

Our ability to operate our business effectively depends in large part on certain administrative and other support functions provided to us by Nabors Corporate and NETV pursuant to the Services Agreement and Development Agreement, respectively, and our ability to operate our business effectively may suffer if we are unable to cost-effectively establish our own administrative and other support functions following the expiration or termination of the Services Agreement and/or the Development Agreement.

Concurrently with the signing of the Business Combination Agreement, we entered into the Services Agreement and the Development Agreement with Nabors Corporate and NETV, respectively. Pursuant to the Services Agreement, we rely on certain administrative and other resources of Nabors Corporate to operate our business. Although each of Nabors Corporate and NETV has performed its obligations under the Services Agreement and Development Agreement, respectively, to date, we cannot ensure that Nabors Corporate and/or NETV will be able to perform in whole or in part, the business it conducts with us pursuant to such agreements. If the Services Agreement is terminated as to any services or entirely, we may not be able to obtain such services at all or obtain the services on terms not as favorable as those in the Services Agreement, and could as a result, suffer operational difficulties or significant losses. Although we and our subsidiaries may receive informal support from Nabors Corporate thereafter, the level of this informal support may diminish following the termination or expiration of the Services Agreement, as we become a more independent company. Any failure or significant interruption of our own administrative systems could result in unexpected costs, impact our results or prevent us from paying our suppliers or employees and performing other administrative services on a timely basis. Any inability to

29

Table of Contents

perform or termination of the Services Agreement or the Development Agreement could have a material adverse effect on our business, financial condition and results of operations.

We may have received better terms from unaffiliated third parties than the terms we have received in the Services Agreement and Development Agreement with NETV.

Pursuant to the Services Agreement, Nabors Corporate, a wholly owned subsidiary of Nabors and affiliate of NETC Sponsor and certain former officers, directors and investors in NETC that are also officers, directors and investors in Nabors, will be entitled to certain fees set forth in statements of work entered into thereunder and the reimbursement of out-of-pocket costs and expenses in exchange for providing services related to operations, engineering, design planning and other operational or technical matters to us. Additionally, pursuant to the Development Agreement, NETV will receive payment from us on a project-by-project basis as detailed in independent project budgets entered into thereunder.

The terms of each of the Services Agreement and Development Agreement were negotiated in connection with the execution of the Business Combination Agreement. As a result, we did not engage in arms’-length negotiations between unaffiliated third parties. The terms of each of the Services Agreement and the Development Agreement may not reflect terms that would have resulted had we engaged in arms’-length negotiations between unaffiliated third parties and any such arms’ length negotiations with an unaffiliated third party may have resulted in more favorable terms to us.

Independent Energy Producer (“IEP”) Business Line

If we are not successful in securing new contracts and / or developing the projects in our pipeline, it could negatively impact our business operations and financial performance.

Our business depends on our ability to win contracts and purchase orders with customers. Contract proposals and negotiations are complex and frequently involve a lengthy bidding and selection process, which is affected by a number of factors. These factors include market conditions, financing arrangements, and required governmental approvals. For example, a customer may require us to provide a bond or letter of credit to protect the customer should we fail to perform under the terms of the contract. If negative market conditions arise, or if we fail to secure adequate financial arrangements or the required government approvals, we may not be able to pursue particular projects, which could adversely affect our profitability. If we fail to complete a project in a timely manner, miss a required performance standard, or otherwise fail to adequately perform on a project, then we may incur a loss on that project, which may reduce or eliminate our overall profitability.

Our engagements will involve complex projects. The quality of our performance on such projects depends in large part upon our ability to manage the relationship with our customers and our ability to effectively manage the project and deploy appropriate resources, including third-party contractors and our own personnel, in a timely manner. If a project is not completed by the scheduled date or fails to meet required performance standards, we may either incur significant additional costs or be held responsible for the costs incurred by the customer to rectify damages due to late completion or failure to achieve the required performance standards. The performance of projects can be affected by a number of factors including unavoidable delays from suppliers and subcontractors, government inaction, public opposition, inability to obtain financing, weather conditions, unavailability of vendor materials, changes in the project scope of services requested by customers, industrial accidents, environmental hazards and labor disruptions. To the extent these events occur, the total costs of the project could exceed our estimates and we could experience reduced profits or, in some cases, incur a loss on a project, which may reduce or eliminate our overall profitability. Further, any defects or errors, or failures to meet our customers’ expectations, could result in claims for damages against us.

We may invest large amounts of resources in our project development and construction activities, in particular our IEP business line, without first securing project financing, which could raise our expenses and make it harder to recoup our investments.

The development and construction of modular CSPv3.0 plants involves numerous risks. We may be required to spend significant sums for preliminary engineering, permitting, legal and other expenses before we can determine whether a project is feasible, economically attractive or capable of being built. In addition, we may choose to bear the costs of such efforts prior to obtaining project financing, getting final regulatory approval and/or our final sale to a customer, if any. Further, we may be unable to secure buyers/offtakers for energy generated by our future plants.

30

Table of Contents

Successful completion of a particular project may be adversely affected by numerous factors, including: failures or delays in obtaining desired or necessary land rights, including ownership, leases and/or easements; failures or delays in obtaining necessary permits, licenses or other governmental support or approvals, or in overcoming objections from members of the public or adjoining land owners; uncertainties relating to land costs for projects; unforeseen engineering problems; access to available transmission for energy generated by our modular CSPv3.0 plants; construction delays and contractor performance shortfalls; work stoppages or labor disruptions and compliance with labor regulations; cost over-runs; availability of products and components from suppliers; adverse weather conditions; environmental, archaeological and geological conditions; continued access to land specified in the ARENA grant for VS1; and availability of construction and permanent financing.

If we are unable to complete the development of one or more of our plants or fail to meet one or more agreed target construction milestone dates, we may incur losses or be liable for damages or penalties that we would not be able to offset, which would have an adverse impact on our net income in the period in which the loss is recognized. We expect that some projects will require working capital to develop and/or build projects. If we are unable to complete a project, the associated working capital investment would also be an exposure that may need to be written off, which would have an adverse impact on our net income in the period in which the loss is recognized.

Our business is subject to risks associated with construction, utility interconnection, cost overruns and delays, including those related to obtaining government permits and other contingencies that may arise in the course of completing installations.

The construction, installation, and operation of our CSPv3.0 technology at a particular site is generally subject to oversight and regulation in accordance with applicable laws and ordinances relating to building codes, safety, environmental protection, and related matters, and typically require various governmental approvals and permits, including environmental approvals and permits, that vary by jurisdiction. In some cases, these approvals and permits require periodic renewal. We expect it will be difficult and costly to track the requirements of every individual authority having jurisdiction over our installations, to design our products to comply with these varying standards, and to obtain all applicable approvals and permits. We cannot predict whether or when all permits required for a given project will be granted or whether the conditions associated with the permits will be achievable. The denial of a permit or utility connection essential to a project or the imposition of impractical conditions would impair our ability to develop the project. In addition, we cannot predict whether the permitting process will be lengthened due to complexities and appeals. Delay in the review and permitting process for a project can impair or delay our and our customers’ abilities to develop that project or may increase the cost so substantially that the project is no longer attractive to us or our customers. Furthermore, unforeseen delays in the review and permitting process could delay the timing of the installation and could therefore adversely affect the timing of the recognition of revenue related to the installation, which could harm our operating results in a particular period.

In addition, the completion of our installations may depend on the availability of and timely connection to the natural gas grid (where applicable) and the local electric grid (where applicable). In some jurisdictions, utility companies or the government may deny our request for connection or may require us to reduce the size of certain projects. Any delays in our ability to connect with utilities, delays in the performance of installation-related services, or poor performance of installation-related services by our general contractors or sub-contractors will have a material adverse effect on our results and could cause operating results to vary materially from period to period.

Furthermore, we may rely on the ability of our third-party general contractors to install our products and to meet our installation requirements. Our work with contractors or their sub-contractors may have the effect of us being required to comply with additional rules, working conditions, site remediation, and other union requirements, which can add costs and complexity to an installation project. The timeliness, thoroughness, and quality of the installation-related services performed by some of our general contractors and their sub-contractors may not meet expectations or standards potentially leading to reduced generation and impact on our financial performance.

CSP plants developed using our technology may not generate the levels of output estimated by our production models.

The modular CSP plants that we will construct will be subject to various operating risks that may cause them to generate less than expected amounts of output. Key risks include our use of a representative year which serves as a reference point against historical data for any given site and is used to generate the expected economic returns and expected energy generation for that site. Further, these risks include a failure or degradation of our, our customers’ or vendors’ equipment; an inability to find suitable replacement equipment or parts; or less than expected solar irradiation. Any extended interruption in the plant’s operation, or failure of the plant for

31

Table of Contents

any reason to generate the expected amount of output, could have a material adverse effect on our business and operating results due to the damage to our reputation and the resulting dissatisfaction of the customer.

We may fail to secure the Major Hazard Facility license and other relevant licenses for VS1 and other projects from relevant federal, state and local regulators.

To construct and operate VS1 and future commercial scale projects using our technology, we (or the respective owner) will have to obtain a Major Hazard Facility license and other relevant licenses from various regulatory bodies. We expect that we will need to obtain similar licenses from appropriate regulatory bodies in connection with our development and operation of other CSP projects. If we are delayed or unable to secure relevant operating permits and approvals, we may be unable to construct our plants as or where planned or according to the expected timelines. If we are delayed or unable to obtain or maintain the licenses necessary to operate VS1 or another CSP plant, the plant in question may be forced to remain shut down for extended periods of time resulting in a materially adverse impact on the overall production of the plant. This may occur before construction, during construction, during commissioning, operations or at any stage in the project development and delivery lifecycle. If we are delayed or unable to obtain the appropriate permits and approvals as and when required, our revenues from the affected projects may be delayed or reduced. Further, our other projects may be delayed or cancelled due to a loss of reputation in the market which in turn could significantly limit our growth.

Original Equipment Manufacturer (OEM) Business Line

An increase in the cost of materials and commodities used as inputs or otherwise in our business could adversely affect our business.

We are exposed to market risk of increases in certain commodity prices of materials, such as steel, glass, concrete and adhesives, which are used as components of supplies or materials utilized in our operations. For example, raw material costs were extremely volatile during the COVID-19 pandemic, in some cases increasing by 30% to 100%. In addition, our customers’ capital budgets may be impacted by the prices of certain materials, and reduced customer spending could lead to fewer project awards and more competition. These prices could be materially impacted by general market conditions (for example, foreign exchange currency fluctuations) and other factors, including Australian trade relationships with other countries or the imposition of foreign currency restrictions and/or tariffs. There can be no assurance that price increases of commodities, if they were to occur, would be recoverable. Additionally, we expect many of our contracts to be fixed price, which would not allow us to adjust our prices and, as a result, increases in material costs could reduce our profitability with respect to such projects.

We intend to manufacture products that we have designed or co-designed and refined over many years that are yet to be produced in commercial quantities.

Our CSPv3.0 technology employs a number of products and components that we have designed or co-designed and refined over many years. This includes but is not limited to heliostats, sodium receivers, sodium/salt heat exchangers and control system software. As these products have been custom designed for use in our CSPv3.0 technology, neither we nor any other party has yet produced these products in commercial quantities. It is possible that, as we ramp up manufacture of these products, the quality of manufactured products is not up to par, the ramp up of manufacturing takes longer than expected and / or costs significantly more than expected. Any of these may result in increased costs, poor performance, a loss of confidence in the technology or limited growth, which may have a material adverse effect on our prospects, financial condition and results of operation.

Operations & Maintenance (“O&M”)

The operation and maintenance of our facilities are subject to many operational risks, the consequences of which could have a material adverse effect on our business, financial condition, results of operations and prospects.

The operation, maintenance, refurbishment, construction and expansion of our facilities involve risks, including breakdown or failure of equipment or processes, fuel interruption and performance below expected levels of output or efficiency. Some of our facilities may require significant capital expenditures to maintain peak efficiency or to maintain operations. There can be no assurance that our maintenance program will be able to detect potential failures in our facilities before they occur or eliminate all adverse consequences in the event of failure. In addition, weather-related interference, work stoppages and other unforeseen problems may disrupt the operation and maintenance of our facilities and may materially adversely affect us.

32

Table of Contents

We plan to enter into ongoing maintenance and service agreements with the manufacturers of certain critical equipment. If a manufacturer is unable or unwilling to provide satisfactory maintenance or warranty support, we may have to enter into alternative arrangements with other providers. These arrangements could be more expensive to us than anticipated and this increased expense could have a material adverse effect on our business. If we are unable to enter into satisfactory alternative arrangements, our inability to access technical expertise or parts could have a material adverse effect on us.

While we will maintain an inventory of, or otherwise make arrangements to obtain, spare parts to replace certain critical equipment and maintain insurance for property damage to protect against certain operating risks, these protections may not be adequate to cover lost revenues or increased expenses and penalties that could result if we were unable to operate our generation facilities at a level necessary to comply with sales contracts.

Our O&M business segment does not yet have adequate resources and sufficient qualified staff to execute the operational tasks needed on our CSPv3.0 plants nor have we demonstrated an operational track record or sufficient financial strength to act as a third-party O&M provider.

Our O&M business segment will require significant financial resources and sufficient qualified staff to execute the O&M tasks that our CSPv3.0 plants will require. To build this business segment, we will need to attract and train appropriate staff and develop specific capabilities needed to operate and maintain our CSPv3.0 plants. In addition, to obtain customers for us to act as a third-party O&M provider, we will need to both demonstrate a track record of successful operation of CSPv3.0 plants and develop and maintain financial strength to give prospective customers confidence that we will continue operating our O&M business segment.

Should we fail to attract and train relevant staff, develop the required O&M capability and a strong operating track record, or develop and maintain sufficient financial strength, our O&M business segment will likely fail to secure contracts on current and future projects resulting in an inability to execute our overall business strategy.

Engineering, Procurement and Construction (“EPC”)

CSPv3.0 construction is complex and engineering, procurement and construction of VS1 and other projects may require us to negotiate, engage and oversee multiple construction companies on Split EPC contracts which may result in delay and cost overruns.

Ideally, and as is customary for utility-scale power plant development projects, we would engage a single party to manage the engineering, procurement, construction, commissioning and ramp up of all projects, including VS1 and other early pipeline projects with that party guaranteeing the contracted terms regarding time, cost and quality. This type of comprehensive engineering, procurement, construction, commissioning and ramp-up service is known as an EPC wrap (“EPC Wrap”). However, we believe that because of the novel requirements of CSPv3.0, an EPC Wrap may not be available in the market or may prove too expensive for VS1 and other projects early in the pipeline. If this is the case, we expect we will have to engage multiple parties to manage different aspects of engineering, procurement, construction, commissioning and ramp up for VS1 and other affected projects. This is known as a split EPC (“Split EPC”).

Projects that may be developed and delivered in the future on a Split EPC basis by us such as VS1 will expose us to interface and performance risks as the prospective owner. In particular, we may incur greater costs (including potential damages) or experience delays in integrating and connecting subsystems of our CSPv3.0 plants that have different EPC contractors because such contractors may fail to properly integrate or coordinate their performance obligations. In addition, simply as a result of requiring multiple EPC contractors, we will be exposed to a greater risk that one such contractor does not perform to our requirements or at all. If VS1 or other projects developed by us are delayed, additional costs are incurred or plant performance is negatively affected, we may suffer reputational damage and may be required to pay liquidated damages to our customers. This could result in reduced demand for our products and higher than expected costs during the early stage of deployment, which in turn may have a material adverse effect on our financial condition and results of operation.

33

Due to the relatively nascent nature of our technology and lack of familiarity of the technology with existing contractors, there is a risk that the contractors we engage fail to follow CSP engineering best practice.

As our CSPv3.0 technology is new, and CSP projects in general have been relatively limited, most contractors in the market are unfamiliar with our CSPv3.0 technology and/or CSP overall. To compensate, contractors may either price their services with a large risk premium which would impact the project economics or underprice their services as they do not understand the risks which could prevent the contractor from meeting its obligations to deliver or operate a plant to our specifications should unexpected issues arise. If we are required to compensate contractors for the risk they perceive to be associated with the new technology, we may incur higher than expected costs which may impair the commercial viability of projects using CSPv3.0. This may require us to commit more capital per project, reduce demand for our products and limit growth which may have a material adverse effect on our prospects, financial condition and results of operation. On the other hand, if our contractors incur unexpected costs when constructing our plants, they may delay constructions, refuse to proceed, fail to deliver the plant to our specifications or demand additional funds. This may lead to cost and schedule overruns, poor plant performance and higher than expected maintenance costs which may have a material adverse effect on our reputation, prospects, financial condition and results of operation.

Further, due to their lack of experience, a busy market for contractors and the novel nature of CSPv3.0, contractors may not have the capability to deliver CSPv3.0 plants meeting our specifications on time, on budget or at all. In addition, because of the limited pool of contractors with even general CSP experience, if a contractor we have engaged to deliver part or all of a CSPv3.0 plant is unable to do so on time, on budget or at all, we may be unable to identify or engage a suitable replacement in a timely manner or at all. Further, in a busy market, limited access to plant and support services (for example, accommodation in nearby towns) may be difficult to secure with respect to the development and/or operation of our plant projects. If we are unable to identify, attract and hire contractors with the capabilities to deliver CSPv3.0 plants meeting our specifications or to secure associated plant and support services, it would have a material adverse effect on our business, results of operations and financial condition.

Risks Relating to Our Projects

Project Completion Risk

We have not yet completed contracting, construction and commissioning of our current projects. There can be no assurance that our projects will operate as described in this prospectus, or at all.

We have not yet entered into binding construction contracts or obtained all necessary environmental, regulatory, construction and zoning permissions for our current projects. There can be no assurance that we will be able to enter into the contracts required for the development of our projects on commercially favorable terms, if at all, or that we will be able to obtain all of the environmental, regulatory, construction and zoning permissions we need. If we are unable to enter into favorable contracts or to obtain the necessary regulatory and land use approvals on favorable terms, we may not be able to construct and operate our assets as described in this prospectus, or at all. Even after they are constructed, our projects must still undergo extensive testing and commissioning before operations can commence. There can be no assurance that we will not need to make adjustments to these facilities as a result of such testing or commissioning, which could cause delays and be costly. Finally, the construction of projects, generally, is inherently subject to the risks of cost overruns and delays. If we are unable to construct, commission and operate all of our projects as described in this prospectus, or, when and if constructed, they do not accomplish the goals described in this prospectus, or if we experience delays or cost overruns during construction, our business, operating results, cash flows and liquidity could be materially and adversely affected. The funding currently proposed is conditional on, for example, a final investment decision being made with respect to VS1.

CSP construction is complex as it is composed of a solar field, power block and thermal energy storage (“TES”) capability.

CSP construction entails a complex composition of a solar field, power block and TES. Certain aspects of CSPv3.0 construction are modular because each solar array in the solar field can be developed independently. However, the remaining construction is similar to traditional fossil fuel fired plants, which include installation of a steam generation system, steam turbine, condenser, air-cooled condensers and plant-control systems. This combination of unit processes requires precise engineering, construction, commissioning and operating capability, some of which we have yet to develop as the technology is commercialized. If we are unable to successfully develop or integrate the various components of CSPv3.0, we may be unable to deliver completed commercialized plants on the timelines we expect or at all, which could reduce revenue, limit our ability to execute our commercialization strategy and harm our reputation.

Projects developed by us may not have adequate transmission access, including permitting, and needed additions and upgrades.

Our generation sites will often need to be connected to the broader energy grid to facilitate construction and operation of the plants and to enable us to deliver energy to market. For “on-grid” projects, connecting to the transmission grid is a fundamental requirement for delivery of energy into the broader energy market. If we are unable to connect to the grid, the energy generated by the plant cannot be converted into revenue to us. Even for “off-grid” projects, connecting to the transmission grid is important for plant construction and maintenance. Further, energy generated by an “off-grid” plant still needs to be delivered to point of use which may or may not be nearby.

In addition to the physical connection to transmission lines, our projects will be impacted by the quantity and quality of the transmission infrastructure. Our plants may be unable to operate at peak capacity due to transmission line congestion, which can be caused by numerous factors such as insufficient available transmission capacity, significant fluctuations in electricity supply/demand profiles, or a high proportion of intermittent generation. Although we will attempt to use transmission studies to evaluate and address such issues, transmission studies may fail to appropriately quantify the amount and likelihood of potential curtailment in the context of a rapidly changing grid.

If we are unable to obtain transmission access that satisfies our requirements, or at all, our business and results of operations may be materially adversely affected.

Our technology has not yet been proven at utility scale and we have limited direct experience with manufacturing our product suite.

Our technology has not yet been implemented at utility scale. Deploying our CSPv3.0 technologies at that scale may present a variety of challenges not faced in smaller implementations, or difficulties present in smaller implementations may be exacerbated.

In addition, we have limited experience manufacturing the components required for our CSPv3.0 plants. This limited experience could create uncertainty on reliability for timely equipment delivery, ease of manufacture and parts replacement, and financial resources available to the project to support a change in manufacturer. This could significantly delay or cease project delivery, including on VS1 and other downstream pipeline projects which could adversely impact our commercialization and growth strategy.

Operations Risk

We may have underestimated increased O&M costs, lost production and / or required maintenance reserves for the first years and the last years of operations and late in project life (“ageing issues”) for projects utilizing our CSPv3.0.

“Teething” issues (unknowns associated with the early stages of a commercialized technology) are common during the first years of operation of new generation technologies. We may have underestimated increased O&M costs, lost production and / or required maintenance reserves for the first years of operation. As we do not have significant directly comparable historical data to guide our estimates, our estimates are based primarily on O&M costs, lost production and required maintenance reserves experienced by other parabolic trough and central tower CSP plants as well as significant management judgement of anticipated differences between those plants and CSPv3.0 plants. If we have underestimated these costs, it could materialize as higher than expected O&M costs, lower production or both. Similar effects could likely also be experienced late in the life of the project, as a result of the ageing of the equipment. This possible deviation from budget is related to the degree to which a technology is proven and operated over time. As CSPv3.0 is just beginning to be commercialized, the lack of an extensive operating track record reduces the confidence in the accuracy of estimated maintenance and repair costs. This could materialize in higher-than-expected costs in the near to medium term resulting in a lower than expected financial performance.

Revenue Risk — Volume

Energy production from our future projects may display high inter-annual volatility at levels in excess of forecast expectations.

Debt instrument rating agencies such as Fitch use the P50 as the basis for a base case production assumption and the one-year P90 as the starting point in the determination of a rating case production assumption. Higher than expected inter-annual variability in production could result in such agencies rating debt instruments for future projects as weaker than anticipated which has the potential

35

Table of Contents

to substantially increase the cost of capital for our CSPv3.0 projects. Further, even if debt instruments for future projects are not allocated any rating by any debt instrument ratings agencies, the criteria used by those ratings agencies generally inform the way that banks and other lenders underwrite debt. Higher than expected inter-annual variability in production could result in a reduction in the debt quantum available to and could pose debt servicing risks for us. This could result in projects employing our technology to no longer be economically viable which in turn could reduce sales of our products and services to customers.

We do not have any operating history / onsite measured data at a commercial scale. Energy production forecasts may be lower than estimated by production modelling forecasts.

Our energy production forecasts are currently based on in-silico modelling based on assumptions from suppliers and relevant engineering estimates and lacks actual operating data at a commercial scale. Our projects, in particular our earliest commercial projects, will be subject to significant uncertainty in their production forecasts which may lead to increased cost of capital or even failure to attract the capital required to deploy CSPv3.0 at a particular location which in turn could materially impede our commercialization and growth strategy.

We believe our projects may be able to derive revenue from regulatory mechanisms that materially insulate revenues from actual power generation alone (e.g., capacity payments); however, these mechanisms may fail to materialize within our target geographies.

CSP is one of the few renewable synchronous generators that can provide market services that intermittent renewable projects cannot such as inertia, system strength, frequency control, capacity credits and others. Accordingly, we believe that projects using our technology are well placed to secure these secondary streams of revenue. However, most of the regulatory mechanisms or proposed mechanisms for rewarding providers of these market services are in early stages of development and they may fail to materialize altogether which may result in reduced revenue and/or more volatile revenue.

Availability levels on our projects could be significantly impacted by the reliability of the technology and the quality of the maintenance services.

Issues within equipment, including Balance of Plant issues, are a key driver of project availability for our CSPv3.0 technology. Our use of parts, systems and components sourced from less established manufacturers or those lacking significant operational track records may expose us to greater risk of equipment performance issues. Further, we may be faced with long lead times to order replacement parts or the need to locate alternative replacement parts should a manufacturer cease production or fail to deliver to us. If we experience significant issues with the equipment we integrate into our plants, or if we are unable to obtain in a timely manner, or at all, replacement or substitute equipment, entire plants may suffer downtime. This in turn could result in lower-than-expected project revenues, harm our reputation within the industry and reduce future demand.

Revenue Risk — Price

Our project pipeline after VS1 may fail to secure long-term power purchase agreements (“PPA”), regulatory incentive mechanisms such as contracts for difference, feed-in tariffs and green certificates.

Our projects utilizing CSPv3.0 may be unable to secure long-term PPAs or regulatory incentive mechanisms from counterparties who are financially strong until CSPv3.0 is considered a “proven” or “mature” technology. Until that time, we may need to enter into PPAs with weaker counterparties and/or PPAs that entail significant exposure to merchant pricing and/or limited access to the market. Less desirable PPA counterparties or terms may lead to increased cost of capital for our projects or even prevent us from obtaining capital for certain projects at all. If we are unable to develop reference projects or are forced to incur substantially greater expenses in doing so, we may be unable to demonstrate that CSPv3.0 is a “proven” and “mature” technology which could have a material adverse effect on our prospects, financial condition and results of operation.

Debt Structure

Our projects may require repayment profiles stretching beyond what existing financing providers may be willing to offer in some or all of our target geographies.

Our CSPv3.0 technology has an assumed economic life of 30-years. However, financing providers may not provide tenors commensurate with the assumed economic life. If financing providers insist on shorter tenors and accelerated debt amortization for debt, our project economics for projects using our CSPv3.0 technology may be weaker than anticipated. Further, to service this shorter-term financing, we may require higher offtake prices than energy consumers would be willing to pay, which could result in projects failing to secure offtake structures or require financing providers to take a refinancing risk. If we are unable to secure satisfactory offtake structures, we may be unable to obtain the capital we need to build and deliver the projects in our pipeline which may have a material adverse effect on our prospects, financial condition and results of operation.

We expect that to obtain any debt financing of the type typically required for large and utility-scale commercial projects, we will need to obtain, among other things, a third-party energy assessment and a third-party engineering report in form and substance satisfactory to prospective lenders. Failure to obtain such assessments and reports could result in delays, increased expenses or project cancellation.

We expect that to obtain the type of debt financing typically required for large and utility-scale commercial power generation projects, we will need to obtain, among other things, a third-party energy assessment and a third-party engineering report in form and substance satisfactory to prospective lenders. These reports are closely scrutinized by prospective lenders. If any of these reports are determined to be inadequate in their scope, quality or authorship, prospective lenders may require higher interest rates or may be unwilling to lend at all. As a result, we may be required to delay or cancel future commercial projects or incur additional expenses to finance such projects.

Risks Relating to Our Corporate Operations

If we are not able to appropriately manage our growth strategy, our business operations and financial results could be adversely affected.

Our expected future growth presents numerous managerial, administrative and operational challenges. Our ability to manage the growth of our operations will require us to continue to improve our management information systems and our other internal systems and controls. In addition, our growth will increase our need to attract, develop, motivate, and retain both our management and professional employees. The inability of our management to effectively manage growth or the inability of our employees to achieve anticipated performance could have a material adverse effect on our business.

We will require a significant amount of capital to achieve our growth plans but obtaining it may be uncertain as we may not be able to secure additional financing on favorable terms, or at all.

While we believe that we will have sufficient funding to execute on our near-term business plan of completing the work and processes to progress VS1 to final investment decision, our funds will be insufficient to fully execute our long-term business and we will need substantial additional funds to meet projected capital expenditures, financing obligations and operating requirements related to the construction and development of projects, which are further described in the section of this prospectus entitled “Business.” We will require a significant amount of capital to achieve our growth plans. At any time we seek to raise additional capital in order to meet various objectives, including developing projects in our project pipeline, developing existing or future technologies and solutions, increasing working capital, acquiring new customers, expanding geographically and responding to competitive pressures, capital may not be available on favorable terms or may not be available at all. Lack of sufficient capital resources could significantly limit our ability to take advantage of business and strategic opportunities and have a material adverse effect on our business prospects, results of operations and financial condition. Any additional capital raised through the sale of equity or debt securities with an equity component may dilute our existing equity owners. If we raise funds through the issuance of debt securities or through loan arrangements, the terms of such securities or loans could require significant interest payments, contain covenants that restrict our business, or include other unfavorable terms. If we are unable to comply with these covenants and service our debt, we may lose control of our business and be forced to reduce or delay planned investments or capital expenditures, sell assets, restructure our operations or submit to foreclosure proceedings, all of which could result in a material adverse effect upon our business. If adequate

37

Table of Contents

additional funds are not available, we may be required to delay, reduce the scope of, or eliminate material parts of our business strategy, including acquiring potential new customers or the continued development of new or existing technologies or solutions and geographic expansion.

A variety of factors beyond our control could impact the availability or cost of capital, including domestic or international economic conditions, increases in key benchmark interest rates and/or credit spreads, the adoption of new or amended banking or capital market laws or regulations, reductions in government incentives or policies that support renewable energy, the re-pricing of market risks and volatility in capital and financial markets, risks relating to the credit risk of our customers and the jurisdictions in which we operate, as well as general risks applicable to the energy sector. Elevated inflation and interest rate increases in the U.S. and globally may prevent us from obtaining financing on terms satisfactory to us or at all. Additionally, pursuant to the terms of the Shareholder and Registration Rights Agreement, in connection with any Superior Capital Raise, (A) if the investor in such Superior Capital Raise receives Ordinary Shares, Nabors will have the right to receive a make-whole issuance of shares so that the aggregate number of Ordinary Shares received by Nabors and its affiliates for their investment under the Nabors Backstop Nabors is equal to the number of Ordinary Shares they would have received had the price for all such shares been the Lower Capital Price and (B) if the investor in such Superior Capital Raise receives any security other than Ordinary Shares, Nabors will have the right to exchange, to the extent there would not be significant impediments to the timely consummation of such an exchange, the equity interests (and the debt interests received in exchange for equity interests in a prior exchange under this provision) still held by Nabors (and its affiliates) that were purchased pursuant to the Nabors Backstop Agreement (excluding any shares that were issued as the Accelerated Earnback Shares) for debt or equity interests on the terms issued in the Superior Capital Raise, so that Nabors (or its affiliates) hold the debt or equity interests they would have held had the investment under the Nabors Backstop Agreement been conducted on the terms of the Superior Capital Raise, in each case, as further described and subject to the conditions set forth in the Shareholder and Registration Rights Agreement. The Shareholder and Registration Rights Agreement also provides that, until the Additional Rights Expiration Date, Nabors will have a consent right over all debt or equity capital we raise (excluding certain issuances of securities pursuant to (i) compensatory stock or option plans, (ii) contracts existing as of the date of the Nabors Backstop Agreement, (iii) securities issued pursuant to convertible securities issued or issuable pursuant to agreements existing as of the date of the Nabors Backstop Agreement and (iv) a bona fide merger or acquisition with an unrelated third party that is, itself, directly or indirectly, an operating company or an owner of an asset in a business synergistic with our business). Together, these provisions could adversely affect our ability to obtain financing on terms acceptable to it, or at all, and may result in dilution to our shareholders. Our financing costs could increase, or future borrowings or equity offerings may be unavailable to us or unsuccessful, which could cause us to be unable to pay or refinance our indebtedness or to fund our other liquidity needs.

We have a history of operating losses and will likely incur substantial additional expenses and operating losses in the future. We may continue to be unprofitable for an extended period of time. Management has concluded that there is, and the report of our independent registered public accounting firm contains an explanatory paragraph that expresses, substantial doubt about our ability to continue as a “going concern”.

We have a history of operating losses and may continue to be unprofitable for an extended period of time. We incurred a net loss of $15.2 million and $6.2 million for the years ended June 30, 2023 and 2022, respectively and $281.5 million and $3.9 for the six months ended December 31, 2023 and 2022, respectively and used net cash in operating activities of $9.1 million and $4.1 million for the years ended June 30, 2023 and 2022, respectively and $28.0 million and $2.8 for the six months ended December 31, 2023 and 2022, respectively. As of June 30, 2023 and December 31, 2023, we had net current liabilities of $23.6 million and net current assets of $7.1 million, respectively, and net total deficit of $29.4 million and equity of $2.2 million respectively. As of June 30, 2023, convertible promissory notes totaling $19.8 million held by, AgCentral due to mature on December 31, 2023, were outstanding and included in current liabilities. We will invest a substantial portion of the proceeds from the Financings and the EDF Note in capital expenditures or in pursuit of development opportunities. We will need to make significant initial investment to complete construction and begin operations of all of our projects. We may not be able to achieve profitability, and if we do, we cannot assure you that we would be able to sustain such profitability in the future.

We are forecasting that we will continue to incur significant operating cash outflows to fund our expansion and to meet all of our obligations, including interest and principal payments on the outstanding debt. As such, our ability to continue as a going concern is principally dependent on our ability to meet our cash flow forecast and our ability to raise funding as and when necessary. As a result of the above, there is material uncertainty related to events or conditions that may cast significant doubt (or raise substantial doubt as contemplated by PCAOB standards) on our ability to continue as a going concern, and therefore, that we may be unable to realize our assets and discharge our liabilities in the normal course of business. The consolidated financial statements do not include any

38

Table of Contents

adjustments that might result from the outcome of this uncertainty. If we were not able to continue as a going concern, or if there were continued doubt about our ability to do so, the value of your investment would be materially and adversely affected.

Our revenue, expenses, and operating results may fluctuate significantly.

Our revenue, expenses, and operating results may fluctuate significantly because of numerous factors, some of which may contribute to more pronounced fluctuations in an uncertain global economic environment. In addition to the other risks described in this “Risk Factors” section, the following factors could cause our operating results to fluctuate:

As a consequence, operating results for a particular future period are difficult to predict and, therefore, prior results are not necessarily indicative of results to be expected in future periods. Any of the foregoing factors, or any other factors discussed elsewhere herein, could have a material adverse effect on our business, results of operations and financial condition that could adversely affect our price.

Our business benefits in part from federal, state and local government support for renewable energy, and a decline in such support could harm our business.

We benefit in part from legislation and government policies that support renewable energy, and energy storage projects that enhance the economic feasibility of our solar energy projects. This support includes legislation and regulations that encourage or in some cases require other customers to procure power from renewable or low-emission sources or otherwise to procure services such as ours; and provide us or our customers with tax and other incentives that reduce costs or increase revenues.

Without this support, our ability to obtain project commitments could be adversely affected. ARENA has announced up to A$65 million on February 13, 2023 for VS1 and up to A$19.5 million and EUR 12.4 million from the HyGATE Program for SM1 on January 27, 2023. The award of this funding is subject to multiple conditions precedent, including but not limited to the ability to provide sufficient equity to meet the balance of funding requirements for the projects, the projects achieving financial close prior to specified dates and securing relevant permitting and approvals such as a grid connection. In addition, such government funding may require the consent of Nabors pursuant to the Shareholder and Registration Rights Agreement or trigger Nabor’s additional rights thereunder, which may make it more difficult to receive these grants.

39

Table of Contents

Securing government support such as grant funding and concessional debt financing may result in increased government oversight and regulation for us or our subsidiaries.

To date, we and our subsidiaries have been the beneficiary of material amounts of grant funding which has assisted in the development and economic feasibility of our solar energy projects. In order to receive such funding, we or our subsidiaries must enter into agreements with the government which regulates how such funding is to be applied and includes detailed reporting and ‘knowledge sharing’ requirements which is intended to assist the government in promoting the expansion of the applicable technology on a commercial scale. As is customary for any concessional or debt financier, the agreements also contain controls and restrictions around how our projects are operated. Therefore, to the extent government grant and concessional financing is accessed, we or our subsidiaries will be subject to various governmental discretions and oversight with respect to how the business is undertaken.

Our business may be harmed if we are unable or fail to properly protect and enforce our intellectual property, and we may also be required to defend against claims or indemnify others against claims that our intellectual property infringes, misappropriates, or violates the intellectual property rights of third parties.

The success of our business depends in part on our proprietary technology, including our software, information, processes and know-how. We rely on patent, copyright, trademark, trade secret and other formal and informal protections to secure, protect, and enforce our intellectual property rights. We rely on a combination of the intellectual property protections afforded by patent, copyright, trademark, and trade secret laws in Australia, the United States, and other international jurisdictions, as well as license agreements and other contractual protections, to establish, maintain and enforce rights and competitive advantage in our proprietary technologies. In addition, we seek to protect our intellectual property rights through non-disclosure and invention assignment agreements with our employees and consultants, and through non-disclosure agreements with our business partners and other third parties.

We may be the target of industrial espionage and it is difficult for us to use Australian government-provided resources to protect against industrial espionage carried out by foreign state actors as we do not currently qualify under the ASIO as an entity that may request a security assessment in Australia and therefore can only require Australian police checks for our employees and cannot require baseline or secret security clearances which include an ASIO assessment. Despite our security measures, this lack of additional government protection could expose us to potential theft of trade secrets, intellectual property and industry know-how by employees who may act for other countries.

Despite our efforts to protect our proprietary rights, certain third parties, including our business partners, may attempt to unlawfully copy, obtain or otherwise use our intellectual property and proprietary information without our consent or our licensors may decline to license necessary intellectual property rights to us on terms favorable to the business. Although we may incur substantial costs in protecting our technology, we cannot be certain that we have adequately protected or will be able to adequately protect it, that our competitors will not be able to utilize our existing technology or develop similar technology independently or that foreign intellectual property laws will adequately cover or protect our intellectual property rights.

Patent, copyright, trademark, and trade secret laws also vary significantly throughout the world. A number of foreign countries do not protect intellectual property rights to the same extent as Australia or the United States. Therefore, our intellectual property rights may not be as strong or as easily enforced outside of Australia or the United States and efforts to protect against the infringement, misappropriation or unauthorized use of our intellectual property rights, technology and other proprietary rights may be difficult and costly. Furthermore, legal standards relating to the validity, enforceability and scope of protection of intellectual property rights are uncertain and any changes in, or unexpected interpretations of, intellectual property laws may compromise our ability to enforce our trade secrets and other intellectual property rights. Failure to adequately protect our owned and exclusively licensed intellectual property rights could result in our competitors using our intellectual property to offer similar products, potentially resulting in the loss of some of our competitive advantage, a decrease in our revenue and reputational harm caused by inferior products offered by third parties, which would adversely affect our business, prospects, financial condition and operating results.

In addition, we rely on our trademarks and brand to distinguish our products and services from those of our competitors and to maintain our goodwill. If we fail to adequately prosecute, maintain, enforce or defend our trademarks, we may lose rights in such trademarks and our brand and business may be adversely affected.

40

Table of Contents

Monitoring unauthorized use of our intellectual property is difficult and costly, and the steps we have taken or will take to protect our intellectual property may not be sufficient to effectively prevent third parties from infringing, misappropriating, diluting or otherwise violating our intellectual property rights. Any enforcement efforts we undertake, including litigation, could require involvement of the licensor, be time-consuming and expensive, and could divert our resources, all of which could harm our business, results of operations and financial condition.

Our patent applications may not result in issued patents or our patent rights may be contested, circumvented, invalidated or limited in scope, any of which could have a material adverse effect on our ability to prevent others from interfering with commercialization of our products.

Our patent portfolio currently consists primarily of patent applications with a few granted patents. We cannot be certain that our patent applications will result in issued patents, which may have a material adverse effect on our ability to prevent others from commercially exploiting products similar to our products to our disadvantage. The status of our patent applications involves complex legal and factual questions and the breadth of claims under any patents that may issue from such patent applications is uncertain. In addition, we cannot be certain that the patent applications that we file will result in patents being issued, or that our patent rights will afford sufficient protections against competitors with similar technology. For example, issued patents may be circumvented or challenged, declared invalid or unenforceable or narrowed in scope. Numerous patents and pending patent applications owned by others exist in the fields in which we have developed and are developing our technology, any number of which could be considered prior art and prevent us from obtaining a patent. As a result, patent application delays could cause delays in recognizing revenue and could cause us to miss opportunities to license patents before other competing technologies are developed or introduced into the market. In addition to those who may claim priority, any of our future or existing patents or pending patent applications (including those we have rights to under exclusive license) may also be challenged by third parties on the basis that our patent rights are otherwise invalid or unenforceable. Furthermore, patent applications filed in foreign countries may be subject to laws, rules and procedures that differ from those of Australia and the United States, and thus we cannot be certain that foreign patent applications related to issued Australia or U.S. patents will be issued or offer similar protections.

We may need to defend ourselves against intellectual property infringement claims, which may be time-consuming and could cause us to incur substantial costs regardless of outcome.

Despite our precautions, it may be possible for third parties to illegally obtain, copy, use, and commercialize our intellectual property without our consent. Unauthorized use of our intellectual property by third parties, and the expenses incurred in protecting and enforcing our intellectual property rights against competitors, may adversely affect our business, prospects, financial condition and operating results.

Companies, organizations or individuals, including our current and future competitors, may hold or obtain patents, trademarks or other intellectual property rights that would prevent, limit or interfere with our ability to make, use, develop, sell, license, lease or market our products or technologies, which could make it more difficult for us to operate our business. In the future, some of our products could be alleged to infringe, misappropriate, or violate existing patents, trade secrets, or other intellectual property of third parties, and we cannot be certain that we will prevail in any intellectual property dispute. In addition, any future litigation required to enforce any patents that may issue on our patent applications, to protect our trade secrets or know-how or to defend ourselves or third parties indemnified by us against claimed infringement of the rights of third parties could harm our business, financial condition, and results of operations. In addition, if a court finds that we have infringed, misappropriated or violated a third party’s intellectual property rights, we may be required to do one or more of the following:

41

Table of Contents

We also license intellectual property from third parties, and we may face claims that our use of this intellectual property infringes or violates the rights of others. In such cases, we may seek indemnification from our licensors as permitted by our license agreements. However, our indemnification rights may be unavailable or insufficient to cover our costs and losses and will depend on our use of the technology or whether we choose to retain control over any potential litigation. Any litigation or claims, whether or not well-founded, could result in substantial costs, negative publicity, reputational harm and diversion of resources and management’s attention.

We may have to share sensitive or confidential information with suppliers and construction partners, which may result in unauthorized disclosure by such third parties to others of trade secrets or know-how resulting in a loss of our competitive advantage.

We rely on proprietary information (such as trade secrets, know-how, and confidential information) to protect intellectual property that may not be patentable, or that we believe is best protected by means that do not require public disclosure. We generally seek to protect this proprietary information by entering into confidentiality agreements, or consulting, services, or employment agreements that contain non-disclosure and non-use provisions with employees, consultants, contractors, scientific advisors, and third parties. However, we cannot guarantee that we have entered into such agreements with each party that has or may have had access to our trade secrets or proprietary information and, even if entered into, these agreements may be breached by such third parties or may otherwise fail to prevent disclosure or third-party infringement, misappropriation, or violation of our proprietary information; may be limited as to their term; and may not provide an adequate remedy in the event of unauthorized disclosure or use of proprietary information. In addition, despite these protections our proprietary information may otherwise become known without fault of us or be independently developed by our competitors or other third parties. To the extent that our employees, consultants, contractors, and other third parties use intellectual property owned by others in their work for us, disputes may arise as to the rights in related or resulting know-how and inventions. Costly and time-consuming litigation could be necessary to attempt to enforce and determine the scope of our proprietary rights, and failure to obtain or maintain protection for our proprietary information could adversely affect our competitive business position, prospects, financial condition and operating results. Furthermore, laws regarding trade secret rights in certain international jurisdictions where we operate may afford little or no protection to our trade secrets. If any of our trade secrets were to be lawfully obtained or independently developed by a competitor or other third party, we would have no right to prevent them from using that trade secret to compete with us in that jurisdiction. If any of our trade secrets were to be disclosed (whether lawfully or otherwise) to or independently developed by a competitor or other third party, it could have a material adverse effect on our business, prospects, operating results, and financial condition.

Our registered or unregistered trademarks or trade names may be challenged, infringed, diluted, tarnished, circumvented or declared generic or determined to be infringing on other marks.

Our registered or unregistered trademarks or trade names may be challenged, infringed, diluted, tarnished, circumvented or declared generic or determined to be infringing on other marks. We may not be able to protect our rights to these trademarks and trade names, which we need to build name recognition among potential collaborators or customers in our markets of interest. At times, competitors may adopt trade names or trademarks similar to our trade names or trademarks, thereby impeding our ability to build brand identity and possibly leading to market confusion. In addition, there could be potential trade name or trademark infringement, dilution or tarnishment claims brought by owners of other trademarks or trademarks that incorporate variations of our registered or unregistered trademarks or trade names. Over the long term, if we are unable to establish name recognition based on our trademarks and trade names, then we may not be able to compete effectively, and our business may be adversely affected. Our efforts to enforce or protect our proprietary rights related to trademarks, trade names, trade secrets, domain names, copyrights or other intellectual property may be ineffective and could result in substantial costs and diversion of resources and could adversely affect our business, financial condition, results of operations and prospects.

We also rely on physical and electronic security measures to protect our proprietary information, but we cannot guarantee that these security measures provide adequate protection for such proprietary information or will never be breached. There is a risk that third parties may obtain unauthorized access to, and improperly utilize or disclose, our proprietary information, which would harm our competitive advantages and reputation. We may not be able to detect or prevent the unauthorized access to, or use of, our information by third parties, and we may not be able to take appropriate and timely steps to mitigate the damages (or the damages may not be capable of being mitigated or remedied).

Our business, financial condition, results of operations and prospects may be materially adversely affected by the extensive regulation of our business.

Our operations are subject to complex and comprehensive federal, state and other regulation. This extensive regulatory framework, portions of which are more specifically identified in the following risk factors, regulates, among other things and to varying degrees, Our industry, businesses, rates and cost structures, operation and licensing of solar power facilities, construction and operation of electricity generation facilities and acquisition, disposal, depreciation and amortization of facilities and other assets, decommissioning costs and funding, service reliability, wholesale and retail competition, and solar renewable energy certificates trading. In our business planning and in the management of our operations, we must address the effects of regulation on our business and any inability or failure to do so adequately could have a material adverse effect on our business, financial condition, results of operations and prospects. Our business, financial condition, results of operations and prospects could be materially adversely affected as a result of new or revised laws, regulations, interpretations or ballot or regulatory initiatives.

Our business is influenced by various legislative and regulatory initiatives, including, but not limited to, new or revised laws, including international trade laws, regulations, interpretations or ballot or regulatory initiatives regarding deregulation or restructuring of the energy industry, and regulation of environmental matters, such as environmental permitting. Changes in the nature of the regulation of our business could have a material adverse effect on our business, financial condition, results of operations and prospects. We are unable to predict future legislative or regulatory changes, initiatives or interpretations, although any such changes, initiatives or interpretations may increase costs and competitive pressures on us, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

Our business may be impacted by climate change, existing or new environmental regulations, and related risks.

Our operations, suppliers, and customers may be directly or indirectly affected by climate change, extreme weather events, and other natural disasters caused by climate change.

Extreme weather events, and other natural disasters caused by climate change may directly impact our ability to develop and operate solar energy projects. This may result in a deterioration in relationship between us and our customers, and reputational damage. It may further result in damages or costs claims from customers to the extent that we are not able to rely on force majeure provisions in our customer contracts.

Extreme weather events and other natural disasters caused by climate change may directly impact our suppliers’ facilities or operations, which may result in delays in materials being delivered to us or increases in costs to minimize or mitigate delays or to secure alternative sources of supply. In such a case, we may not, however, be successful in finding alternative sources and we may not be able to fulfill our commitments to our customers. This may result in a loss of anticipated sales, a deterioration in relationship between us and our customers, and reputational damage. It may further result in damages or costs claims from customers to the extent that we are not able to rely on force majeure provisions in our customer contracts, or to pass on such liabilities to our suppliers.

Our costs may increase as we implement initiatives in response to climate change, either voluntarily or in response to requirements imposed by customers, suppliers or regulators. Suppliers may pass on cost increases related to the impact of climate change on their own operations, and we may not be able to pass these cost increases on to customers. Our costs may also increase as a result of increased taxes or tariffs related to climate change.

Changing regulatory requirements or customer, consumer or investor standards, and expectations in relation to climate change, sustainability and environmental matters may increase our operational and compliance costs.

We, our suppliers and service providers are required to comply with environmental laws and regulations. The production and transportation of products and other inputs in the project development process involves the risk of accidents, spills or contamination. Any of these occurrences could cause harm to the environment, which may lead to disruption in our operations and supply chain, regulatory sanctions and remedial costs, and reputational harm, any of which could negatively impact our operating and financial performance.

Any reductions or modifications to, or the elimination of, governmental incentives or policies that support renewable energy in general, and CSP/CST in particular, could have a material adverse effect on our business, financial condition, results of operations and prospects.

We currently depend heavily on government policies that support utility scale renewable energy and enhance the economic feasibility of developing and operating solar energy projects in regions in which we operate or plan to develop and operate renewable energy facilities. The Australian government provides incentives, such as Large-scale Generation Certificates that support or are designed to support the sale of energy from utility scale renewable energy facilities, such as wind and solar energy facilities. As a result of budgetary constraints, political factors or otherwise, governments from time to time may review their laws and policies that support renewable energy and consider actions that would make the laws and policies less conducive to the development and operation of renewable energy facilities. Any reductions or modifications to, or the elimination of, governmental incentives or policies that support renewable energy or the imposition of additional taxes or other assessments on renewable energy, could result in, among other items, the lack of a satisfactory market for the development and/or financing of new renewable energy projects, our abandonment of the development of renewable energy projects, a loss of our investments in the projects and reduced project returns, any of which could have a material adverse effect on our business, financial condition, results of operations and prospects.

Our business will depend on experienced and skilled personnel and substantial specialty subcontractor resources including key offshore personnel that may be required (e.g., turbine supplier) to verify satisfactory installation of various components of our plants. If we lose key personnel or if we are unable to attract and integrate additional skilled personnel, it will be more difficult for us to manage our business and complete projects.

The success of our business and construction projects will depend in large part on the skill of our personnel and on trade labor resources, including those with certain specialty subcontractor skills. Competition for personnel, particularly those with expertise in the energy services and renewable energy industries, is high. In the event we are unable to attract, hire and retain the requisite personnel and subcontractors, we may experience delays in completing projects in accordance with project schedules and budgets.

Further, any increase in demand for personnel and specialty subcontractors may result in higher costs, causing us to exceed the budget on a project. Either of these circumstances may have an adverse effect on our business, financial condition and operating results, harm our reputation among and relationships with our customers and cause us to curtail our pursuit of new projects.

Our future success is particularly dependent on the vision, skills, experience and effort of our senior management team, including our executive officers. If we were to lose the services of any of our executive officers or key employees, our ability to effectively manage our operations and implement our strategy could be harmed and our business may suffer.

Security and privacy breaches, loss of proprietary information, and service interruptions caused by computer malware, viruses, ransomware, hacking, phishing attacks, and other network disruptions could have a negative impact on our business, financial condition, and operations.

Despite our information security measures in place designed to prevent computer malware, viruses, physical or electronic break-ins and similar disruptions from affecting our systems, if such incidents occur these could lead to interruption, delays, and failures in our services and operations and loss, misuse or theft of data. Computer malware, viruses, ransomware, hacking, phishing attacks or denial of service, against online networks have become more prevalent and sophisticated and may occur on our systems. Any attempts by cyber attackers to disrupt our or our service providers’ services or systems, if successful, could harm our business, result in liability to data subjects, governmental authorities or third parties, result in the misappropriation of funds or data, be expensive to remedy and damage our reputation or brand. Insurance may not be sufficient to cover significant expenses and losses related to cyber-attacks. Notwithstanding the security measures we have implemented, such as managed security services, that are designed to detect and protect against cyber-attacks, and any additional measures we may implement or adopt in the future, our facilities and systems, and those of our third-party service providers, could be vulnerable to security breaches, computer viruses, lost or misplaced data, programming errors, scams, burglary, human errors, acts of vandalism, or other events. Efforts to prevent cyber attackers from entering computer systems are expensive and time-consuming to implement, and despite contractual obligations, we may not be able to cause the implementation or enforcement of such preventions with respect to our third-party vendors. Though it is difficult to determine what, if any, harm may directly result from any specific interruption or attack, any failure to maintain performance, reliability, security and availability of systems and technical infrastructure may, in addition to other losses, harm our reputation, brand and ability to attract customers and result in legal and regulatory liabilities.

There are several factors ranging from human error to data corruption that could materially impact the efficacy of any processes and procedures designed to enable us or our customers to recover from a disaster or catastrophe, including by lengthening the time services are partially or fully unavailable to customers and users. It may be difficult or impossible to perform some or all recovery steps and continue normal business operations due to the nature of a particular cyber-attack, disaster or catastrophe or other disruption, especially during peak periods, which could cause additional reputational damages, or loss of revenues, any of which would adversely affect our business and financial results.

The management team has limited experience in operating a public company in the United States.

Our executive officers have limited experience in the management of a publicly traded company in the United States. The management team may not successfully or effectively manage the transition to a public company that will be subject to significant regulatory oversight and reporting obligations under U.S. federal securities laws. Their limited experience in dealing with the increasingly complex laws pertaining to public companies could be a significant disadvantage in that it is likely that a significant amount of their time may be devoted to these activities, which will result in less time being devoted to the management and growth of the company. We may not have adequate personnel with the appropriate level of knowledge, experience and training in the accounting policies, practices or internal control over financial reporting required of public companies. The development and implementation of the standards and controls and the hiring of experienced personnel necessary to achieve the level of accounting standards required of a public company may require costs greater than expected.

We may be deemed an energy supplier under local or international laws and may become subject to extensive and complex legislation and regulations or may in certain cases be required to register as a regulated entity under those jurisdictions’ laws and regulations.

We may be subject to energy supplier laws and regulations in the jurisdictions in which we conduct business or have assets. These laws and regulations may apply if we are deemed to be an energy supplier under Australian laws or the laws of other jurisdictions in which we conduct business or have assets. If these laws and regulations apply to us, then we may need to register as a regulated entity in the relevant jurisdiction and may also be subject to extensive and complex laws and regulations.

Risks Relating to VS1

The VS1 reference project is important to the future of the business and requires a substantial scale up relative to the Jemalong Solar Station (“JSS Demonstration Plant”) and carries significant risk associated with factors such as technology readiness, organizational capability to deliver and production ramp up.

VS1 is our reference project to demonstrate the viability of CSPv3.0 at a utility scale. Accordingly, the success of VS1 is important to the future of our business. VS1 may be delayed due to a variety of factors outside of our control such as a complex grid connection process, permitting delays, updated legislation forcing permits to be re-acquired, failure to attract the required financing or to satisfy conditions precedent to such financing, construction delays, cost overruns, loss / theft of a key piece of equipment, longer than expected commissioning process and a slower than expected ramp-up of production post commissioning. A delay or failure in the delivery of VS1 could materially impact our overall growth strategy and substantially reduce the potential to commercialize our product offering. Additionally, the secured concessional financial support from the Australian government for VS1 is conditioned upon our achievement of financial close of VS1 by the end of March 2024. We expect to agree with ARENA to push back the anticipated financial close from the end of March 2024 to September 2024 with the delay caused by certain detailed work on VS1 being delayed due to limitations on our capital resources.

In addition, the VS1 project involves a substantial scale up relative to the JSS Demonstration Plant and carries significant risk associated with factors such as technology readiness, organizational capability to deliver and production ramp up. We have never delivered a commercial project. The last successful project delivered by us was a 1.1MW grid-connected pilot plant that was decommissioned in 2020. We may experience issues with scaling up our technology to the size required for VS1 and other large and utility-scale projects which may have a material adverse effect on our business in the form of higher costs, reduced demand and delayed growth. A delay or failure in the delivery of VS1 could materially impact our overall growth strategy and substantially reduce the potential to commercialize our product offering.

We are only a 50% owner of, and do not outright control, SiliconAurora.

SiliconAurora’s support may be important in ensuring the success of VS1 and other projects in our project pipeline. Should our relationship with our SiliconAurora joint venture partner, 1414 Degrees, turn adversarial, or should we otherwise fail to appropriately manage this business with 1414 Degrees, it may significantly delay VS1 and/or other projects in our project pipeline and have material adverse outcomes for the overall prospects of our business.

Risks Relating to Our Technology

We may be unable to adapt our technologies and products to meet shifting customer preferences or industry regulations, and our rivals could create products that reduce the demand for our offerings.

Rapidly changing technologies and industry standards, along with frequent new product introductions, characterize the renewable energy industry and the industries of many of our customers and potential customers. Our financial performance depends, in part, on our ability to design, develop, manufacture, assemble, test, market and support new products and technology enhancements on a timely and cost-effective basis.

We have not commercialized any of our products. To date, principal focus has been on research and development activities (including operating the Jemalong Demonstration Plant for 32 months), to improve our technology and make our product offerings more attractive to potential customers. These activities are subject to various risks and uncertainties we are not able to control, including changes in customer demand, negative market perceptions of CSP technology due to known issues associated with the deployment of previous iterations of CSP technology (as discussed elsewhere in this prospectus) or industry standards and the introduction of new or superior technologies by others. Moreover, any failure by us in the future to develop new technologies or to timely react to changes in existing technologies could materially delay our development of new products, which could result in product obsolescence, decreased revenues and a loss of market share to competitors. In addition, products or technologies developed by others may render our products or technologies obsolete or non-competitive. Further, if our products are not in compliance with prevailing industry standards, such non-compliance could materially and adversely affect our financial condition, cash flows and results of operations.

The development and delivery of our modular CSPv3.0 plants will require substantial funding. Our projects may rely on outside sources to finance this, and such financing may not be available on favorable terms or at all.

To date, we have relied to a significant extent on government funding, in the form of grants, to develop and validate our technology. Similarly, we have conditional government funding approval for up to AUD 65 million grants and up to AUD 110 million in concessional financing for the development of VS1 and we and our consortium partner, Mabanaft, conditional government funding for up to AUD 19.5 million and EUR 12.4 million for the development of SM1. How much of this financing we receive will depend on our ability to satisfy certain funding and/or grant conditions (for example, with respect to the AUD 110 million concessional financing for VS1, a final investment decision being made), and there can be no assurance that we will be able to meet such conditions. For more information, please see the risk factor entitled “Our business benefits in part from federal, state and local government support for renewable energy, and a decline in such support could harm our business.” In addition, the conditional government funding and concessional financing will not cover the full costs of development and delivery of VS1 and SM1. Accordingly, we and where applicable, our consortium partners, will need to obtain and invest significant capital to these projects in order to complete them.

We expect that future projects we undertake for our own account will require primarily private, as opposed to government financing to develop. Similarly, we expect that our projects for customers will typically be financed by private third parties. For the modular concentrated solar power plants that we develop, we expect our customers to rely on a combination of their balance sheets and project-finance debt to fund construction costs. If our customers are unable to raise funds on acceptable terms when needed, we may be unable to secure customer contracts, the size of contracts we do obtain may be smaller or we could be required to delay the development and construction of projects, reduce the scope of those projects or otherwise restrict our operations. Any inability by our customers to raise the funds necessary to finance our projects could materially harm our business, financial condition and operating results.

We expect to face significant competition in the future as the CSP industry and wider energy industry develop.

The landscape of the energy industry is in flux driven by the global drive to decarbonize the existing energy system. Driven by the increased investment that is expected to be deployed into this sector globally. This could result in the creation of new technologies that are not yet available and/or material improvements to other technologies that may have the potential to outcompete our CSPv3.0 technology and be better suited to serve demand that we expect we are well positioned to serve in the current context. This competition may come from competitors within the CSP industry or from the wider energy industry. Should this materialize, the portion of the total addressable market that we could capture will be lower than expected which would translate to lower than expected revenues that could harm the business.

We have not yet integrated molten salt TES into our overall technology offering.

The incorporation of molten salt TES is a key driver of the overall economics of our technology. Molten salt is widely deployed across the world in multiple CSP projects as a TES. However, we have not integrated molten salt TES in the projects we have completed to date. Failure to integrate molten salt TES appropriately at VS1 and other future projects could have a material adverse effect on the attractiveness of our technology to customers which could significantly impede our growth strategy, reduce revenues and materially harm our business.

We use liquid sodium, a material that is highly reactive and can be dangerous when inappropriately handled, as an HTF.

The use of liquid sodium metal as the HTF from the solar receivers to the molten salt heat transfer system is the crucial innovation that unlocks the inherent modularity that is a key benefit of our CSPv3.0 system. Liquid sodium, if improperly managed, could burn to create large volumes of acrid smoke or react explosively if exposed to water. We have, in the past, experienced sodium loss of containment events at the JSS Demonstration Plant in 2015. Further, use of sodium in CSP by other companies stalled following a major loss of containment at the Plataforma Solar de Almeria. If there is a major incident involving sodium in VS1 or other downstream projects developed using our technology, concerns about the safety and viability of using sodium in CSP could negatively affect market perception of the technological and commercial readiness of our technology. If this occurs, demand for our technology may be reduced which could result in a reduction in revenue and may adversely affect the growth prospects of the business. Loss of containment incidents in VS1 could also result in remedial liabilities, fines, or penalties under environmental laws, which may increase costs or restrict our operating activities.

Hydrogen, methanol and other hydrogen derivatives are flammable fuels that are inherently dangerous substances.

We expect that some customers will use our systems to create hydrogen gas and downstream derivatives such as methanol through electrolysis, distillation and other similar industrial processes. While our products do not use this fuel in a combustion process, hydrogen gas is a flammable fuel that could leak and combust if ignited by another source, which could result in liability under environmental or occupational health and safety laws. Further, any such accidents involving our products or other products using similar flammable fuels could materially suppress demand for, or heighten regulatory scrutiny of, our products.

The risk of product liability, environmental, or occupational health and safety claims and associated adverse publicity is inherent in the development, manufacturing, marketing and sale of hydrogen, a flammable gas. Any liability for damages resulting from malfunctions or design defects could be substantial and could materially adversely affect our business, financial condition, results of operations and prospects.

Our, and our potential customers’ green hydrogen and downstream derivative production plants may seek to purchase an insurance policy to insure such project to mitigate this operational risk, but due to the nascent industry and market for these products, it is unknown what the financial burden might be of any such insurance policy, and we, or our customers, may determine that the costs of insuring for these risks make it impractical to obtain insurance. Accordingly, we cannot guarantee that each plant will purchase insurance nor that any insurance coverage purchased will be adequate. Any uninsured occurrence of business disruption, litigation, natural disaster, or significant damages to uninsured equipment or technology infrastructure could result in substantial costs and diversion of resources and could adversely affect our financial condition and results of operations.

CSPv3.0 requires the use of a number of complex components, equipment and interconnections, some of which have been custom designed by or for us and have not been used in commercial projects in the past. Any failure of such components, equipment or interconnections could result in delays, impaired performance, increased costs and damage to our reputation.

The complexity and ongoing development of our product designs and manufacturing processes could lead to design or manufacturing problems. Problems might result from a number of factors, including design defects, materials failure, failure of components manufactured by our suppliers to meet our specifications, contamination in the manufacturing environment, impurities in the materials used, and unknown sensitivities to process conditions such as temperature and humidity, and equipment failures. Any errors or defects could:

The occurrence of any one or more of these events could adversely affect our business, reputation and operating results.

The performance of our technology may be affected by field conditions and other factors outside of our control, which could result in harm to our business and financial results.

Field conditions, such as the natural elements and utility processes which vary by region and may be subject to seasonal fluctuations, are not always possible to predict until the CSP equipment is in operation. Although we believe we have designed our systems to successfully withstand the variety of field conditions we expect to encounter as we move into new geographies and deploy new service configurations, we may encounter new and unanticipated field conditions. Adverse impacts on performance may require us to incur significant re-engineering costs or divert the attention of our engineering personnel from product development efforts. Furthermore, we may be unable to adequately address the impacts of factors outside of our control in a manner satisfactory to our customers. Any of these circumstances could significantly and adversely affect customer satisfaction, market acceptance, and our business reputation.

Our technology has undergone preliminary modelling using a historical weather profile, which refers to a set of data that reflects past weather patterns in a particular area. This historical data is used to simulate the performance of our technology under various weather conditions. However, the use of historical weather data is not as accurate as forecasted weather data, which takes into account real-time weather information to provide a more accurate prediction of future weather patterns (but cannot guarantee future weather outcomes).

The equipment we procure and manufacture may have shorter lifetime and / or degrade faster than expected resulting in the loss of a competitive advantage, which could result in harm to our projects, reputation in the market and financial results.

Our growth strategy depends in part on developing durable systems, products, technologies, and offering maintenance services. These reusable systems, products, technologies and systems will have a limited useful life. While we intend to design our products and

48

Table of Contents

technologies for a certain lifespan, which corresponds to a number of cycles, there can be no assurance as to the actual operational life of a product or that the operational life of individual components will be consistent with its design life. A number of factors will impact the useful lives of our products and systems, including, among other things, construction, the durability of their component parts and availability of any replacement components, and the occurrence of any anomaly or series of anomalies or other risks affecting the technology during installation and operation. In addition, any improvements in technology may make our existing products, designs, or any component of our products prior to the end of its life obsolete. If our systems, products, technologies and services and related equipment have shorter useful lives than we currently anticipate, this may lead to delays in increasing the rate of our follow on work and new business, which would have a material adverse effect on our business, financial condition, and results of operations. In addition, we are continually learning, and as our engineering and manufacturing expertise and efficiency increases, we aim to leverage this learning to be able to manufacture and install our products and equipment using less equipment, which could render our existing inventory obsolete.

Leaks have occurred in the floors of hot-salt tanks at operating CSP plants, and the advanced hot tank design we use has not been tested commercially.

Several leaks in the floors of hot-salt tanks have occurred at operating CSP plants using earlier versions of CSP technology. While the cause for these tank failures have generally been reported as construction errors, the leaks could also potentially be caused by friction forces between the tank floor and the foundations. Repairing the tanks may create delays that significantly degrade plant availabilities. In addition, salt that leaks into the foundation can introduce increased thermal losses, cause overheating of the foundation, and produce nitrogen oxides. There are no standard designs for molten salt tanks with the American Petroleum Institute Standard 650 (limited to 2.5 psi and 200°F) the closest design code for these tanks. The advanced hot tank design we use, which was developed by a consortium including us, is a new tank design that has not yet been demonstrated at commercial scale, and there is no guarantee that this design will work as intended. Should this tank design fail, plants using our technology could cease operations for extended periods of time, which may damage our reputation in the market resulting in significantly reduced orders from customers and fewer developed projects, which may materially harm the prospects of the business.

Certain steam generation systems (“SGS”) and heat exchangers used in existing CSP projects have become subject to defects or issues that limit their use. Designs developed by us and/or our supplier partners to overcome such defects/issues may not be effective.

There have been some issues with heat exchangers and SGS used in existing CSP projects having known manufacturing defects, specifically on the tube to tubesheet welding of those heat exchangers and SGS. Additionally, such heat exchangers and SGS have known issues regarding their process design, most notably being subjected to excessive temperature gradients during operation. We have developed a system to minimize the excessive temperature gradients referenced above, and employ an Internal Bore Welded design for the tube-to-tubesheet in our heat exchangers and as specified to the preferred SGS supplier. However, this combination and integration of process and equipment design has not been demonstrated at commercial scale and there is no guarantee that it will work once scaled up. Should the designs developed by us and our supplier partners fail to perform as expected in mitigating these defect/issues to the extent such heat exchangers and SGS are used in our projects, our competitive edge across our overall system design may fail to materialize, which could result in lower than expected reliability for the technology potentially resulting in lower than expected deployment of our technology, which may in turn materially harm the prospects of our business.

Our performance and dynamic models have limited validation at a commercial scale and are primarily based on in-silico analyses.

We have developed a one-minute production modelling software and a one-second dynamic modelling software that projects the overall performance of the system from a commercial and technical perspective ahead of the physical plants being developed. The models have been developed primarily from in-silico analyses completed using supplier data and internal engineering information. The commercial and commercial reference scale plants that have been modelled have not been developed or verified against existing plants in operation, and it is possible that the models do not appropriately account for the overall performance of our technology. This could result in our technology underperforming our projections and have a negative impact on our growth rates.

Environmental and Cultural Risks

Future CSP plants we develop may indirectly harm local animal or plant populations, which may expose us to reputational and other risks.

The known environmental impacts of CSP plants on local ecosystems can be significant, and can include disturbances to the ecosystem, loss of ecosystem functions, and indirect mortalities to local fauna. Mortalities of birds are a primary concern due to collisions with top mirrors and buildings and heat shock from concentrated light beams. Birds and insects may also mistake reflecting surfaces for air or water and collide with those surfaces. If built on agricultural land, vegetation growth below and between solar collectors can contribute to fire risk, and herbicides used to prevent growth can have toxic effects and persist in the soil. CSP plants may also cut off migration routes and introduce alien species to the area.

Additionally, CSP plants are often located in areas with high biodiversity, and their construction and operation can lead to habitat loss and fragmentation. This can have significant impacts on local ecosystems, potentially leading to the endangerment or extinction of species. Further, the mirrors used in CSP plants can cause glare, which can be harmful to birds and other flying animals, leading to collisions and injury or death. Such incidents may result in negative community action or sentiment, legal liabilities, and/or reputational damage for us.

Future CSP plants we develop may displace or otherwise adversely impact indigenous communities, leading to reputational and other damage for us.

The introduction of a CSP plant in a given area may displace indigenous communities occupying that area, potentially disrupting traditional livelihoods and leading to adverse social and economic impacts for those communities. Any loss of traditional land use, sacred sites and/or cultural practices by indigenous communities due to changes in land ownership and use related to a CSP plant may lead to cultural loss and trauma for indigenous communities occupying the relevant area. Additionally, conflicts may arise between our interests and those of the indigenous communities regarding the use of natural resources (such as water) on or around land occupied by those indigenous communities. The realization of these risks may result in negative community action or sentiment, legal liabilities, and/or reputational damage for us.

Plants using our technology are large industrial facilities that may attract negative attention from protestors and / or local communities around the presence of an industrial asset.

Industrial facilities can generally only be developed in designated areas especially in locations with less available land than Australia. This could result in public opposition and / or local community action against projects which could result in a loss of our social license to operate and lawsuits which could have an adverse impact on our reputation, business, prospects and results of operation.

Financial, Tax and Accounting Risks

We have identified material weaknesses in our internal control over financial reporting. If we are unable to remediate these material weaknesses, or if we identify additional material weaknesses in the future or otherwise fails to maintain an effective system of internal control over financial reporting, this may result in material misstatements of our consolidated financial statements or cause us to fail to meet our periodic reporting obligations.

As a public company, we will in the future be required to provide management’s attestation on internal control over financial reporting. Management may not be able to effectively and timely implement controls and procedures that adequately respond to the increased regulatory compliance and reporting requirements that are applicable after the Business Combination. If we are not able to implement the additional requirements of Section 404(a) of the Sarbanes-Oxley Act in a timely manner or with adequate compliance, we may not be able to assess whether our internal control over financial reporting is effective, which may subject us to adverse regulatory consequences and could harm investor confidence.

In connection with the preparation of our consolidated financial statements for the years ended June 30, 2023 and 2022 material weaknesses were identified in our internal control over financial reporting. A material weakness is a deficiency, or a combination of

50

Table of Contents

deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.

The material weaknesses referenced above are described below:

In order to maintain and improve the effectiveness of our internal control over financial reporting, we anticipate that we will continue to expend, significant resources, including accounting-related costs and significant management oversight. Any failure to maintain effective disclosure controls and internal control over financial reporting could adversely affect our business and operating results and could cause a decline in the price of the Ordinary Shares. These material weaknesses will not be considered remediated until the mitigating controls have operated for the required period of time and until the operating effectiveness of the controls has been validated, through testing, by management.

Operating as a newly listed public company will increase our costs and may disrupt the regular operations of our business. Our management has limited experience in operating a public company.

As a new public company, we incur significant legal, accounting, regulatory, finance, insurance, investor relations, and other expenses that we did not incur as a private company. Having gone public through a merger with a special purpose acquisition company (“SPAC”), there are additional and specific rules and regulations applicable to our operations. Compliance with public company, and SPAC specific, regulatory requirements will increase our legal and financial compliance costs and we may need to hire additional staff with appropriate public company experience, particularly those with technical accounting knowledge. We may not accurately predict or estimate the amount of additional costs we may incur in the future as a result of being a public company or the timing of such costs.

We are required to prepare financial statements on a timely basis that comply with SEC reporting requirements and maintain effective internal controls over financial reporting. The additional demands associated with being a public company may disrupt our regular business operations by diverting management’s attention away from revenue producing activities to compliance and administrative oversight, adversely affecting our ability to attract and complete business opportunities and increasing the difficulty in both retaining professionals and managing and growing our businesses. In addition, changing laws, regulations, and standards relating to corporate governance and public company disclosures are creating uncertainty for public companies, especially those who have gone public through a SPAC merger transaction, further increasing legal and financial compliance costs, and making some activities more time consuming. We will continue to invest resources to comply with evolving laws, regulations, and standards, and this investment may result in increased general and administrative expenses. Failure to comply with any laws or regulations applicable to us as a public company may result in legal proceedings and/or regulatory investigations, and may cause reputational damage, any of which could harm our business, financial condition and results of operations.
