**No Offer or Solicitation**

This filing is for information purposes only and is not intended to and does not constitute, or form part of, an offer, invitation or the solicitation of an offer or invitation to purchase, otherwise acquire, subscribe for, sell or otherwise dispose of any securities, or the solicitation of any vote or approval in any jurisdiction, pursuant to the Potential Business Combination or otherwise, nor shall there be any sale, issuance or transfer of securities in any jurisdiction in contravention of applicable law.

**Forward-Looking Statements**

Certain statements included in this Form 8-K and the investor presentation are not historical facts but are forward-looking statements, including for purposes of the safe harbor provisions under the United States Private Securities Litigation Reform Act of 1995. Forward-looking statements generally are accompanied by words such as "believe," "may," "will," "estimate," "continue," "anticipate," "intend," "expect," "should," "would," "plan," "project," "forecast," "predict," "potential," "seem," "seek," "future," "outlook," "target," and similar expressions that predict or indicate future events or trends or that are not statements of historical matters, but the absence of these words does not mean that a statement is not forward-looking. These forward-looking statements include, but are not limited to (1) statements regarding estimates and forecasts of financial, performance and operational metrics and projections of market opportunity; (2) references with respect to the anticipated benefits of the Potential Business Combination and the projected future financial and operational performance of US Elemental ("NewCo") following the Potential Business Combination, which may be affected by, among other things, competition, the ability of NewCo to grow and manage growth profitably, maintain relationships and retain its management and key employees; (3) the sources and uses of cash of the Potential Business Combination; (4) the anticipated capitalization and enterprise value of NewCo following the consummation of the Potential Business Combination; (5) statements regarding NewCo's operations following the Potential Business Combination; (6) the amount of redemption requests made by the Company's public shareholders; (7) current and future potential commercial relationships; (8) plans, intentions or future operations of NewCo or HiTech Minerals, Inc. ("HiTech Minerals"), including relating to the finalization, completion of any studies, feasibility studies or other assessments or relating to attainment, retention or renewal of any assessments, permits, licenses or other governmental notices or approvals, or the commencement or continuation of any construction or operations of plants or facilities; (9) the ability of NewCo to issue equity or equity-linked securities in the future; (10) the outcome of any legal proceedings that may be instituted against Jindalee, the Company, HiTech Minirals and NewCo (together, the "Contracting Parties"); (11) changes to the proposed structure of the Potential Business Combination that may be required or appropriate as a result of applicable laws or regulations; (12) the ability to meet stock exchange listing standards following the Potential Business Combination; (13) the risk that the Potential Business Combination disrupts current plans and operations of HiTech Minerals; (14) the availability of federal, state or local government support, and risks related to extensive regulation, compliance obligations and rigorous enforcement by federal, state, and non-U.S. governmental authorities; and (15) expectations related to the terms and timing of the Potential Business Combination and the ability of the parties to successfully consummate the Potential Business Combination. These statements are based on various assumptions, whether or not identified in the investor presentation, and on the current expectations of the Contracting Parties' management and are not predictions of actual performance. These forward-looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied on by any investor as, a guarantee, an assurance, a prediction or a definitive statement of fact or probability. Actual events and circumstances are difficult or impossible to predict and will differ from assumptions. Many actual events and circumstances are beyond the control of the Contracting Parties. These forward-looking statements are subject to a number of risks and uncertainties, as set forth in the slide entitled "Risk Factors" in the appendix to the investor presentation and those set forth in the section entitled "Risk Factors" and "Cautionary Note Regarding Forward-Looking Statements and Risk Factor Summary" in the Company's Annual Report on Form 10-K for the year ended December 31, 2024, and in those other documents that the Company has filed, or that the Company and NewCo will file, with the U.S. Securities and Exchange Commission. If any of these risks materialize or our assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. The risks and uncertainties above are not exhaustive, and there may be additional risks that none of the Contracting Parties presently know or that they currently believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward looking statements reflect relevant Contracting Parties' expectations, plans or forecasts of future events and views as of the date of the investor presentation. Each of the Contracting Parties anticipate that subsequent events and developments will cause those assessments to change. However, while the Contracting Parties may elect to update these forward-looking statements at some point in the future, each of the Contracting Parties specifically disclaim any obligation to do so. These forward-looking statements should not be relied upon as representing any of the Contracting Parties' assessments as of any date subsequent to the date of the investor presentation. Accordingly, undue reliance should not be placed upon the forward-looking statements.

INVESTOR PRESENTATION \| 3 U.S. Disclaimers Continued Forward - Looking Statements Continued (9) the ability of NewCo to issue equity or equity - linked securities in the future ; (10) the outcome of any legal proceedings that may be instituted against the Contracting Parties ; (11) changes to the proposed structure of the Potential Business Combination that may be required or appropriate as a result of applicable laws or regulations ; (12) the ability to meet stock exchange listing standards following the Potential Business Combination ; (13) the risk that the Potential Business Combination disrupts current plans and operations of the Company ; (14) the availability of federal, state or local government support, and risks related to extensive regulation, compliance obligations and rigorous enforcement by federal, state, and non - U . S . governmental authorities ; and (15) expectations related to the terms and timing of the Potential Business Combination and the ability of the parties to successfully consummate the Potential Business Combination . These statements are based on various assumptions, whether or not identified in these Presentation Materials, and on the current expectations of the Contracting Company's management and are not predictions of actual performance . These forward - looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied on by any investor as, a guarantee, an assurance, a prediction or a definitive statement of fact or probability . Actual events and circumstances are difficult or impossible to predict and will differ from assumptions . Many actual events and circumstances are beyond the control of the Contracting Parties . These forward - looking statements are subject to a number of risks and uncertainties, as set forth in the slide entitled "Risk Factors" in the appendix to these Presentation Materials and those set forth in the section entitled "Risk Factors" and "Cautionary Note Regarding Forward - Looking Statements and Risk Factor Summary" in Constellation's Annual Report on Form 10 - K for the year ended December 31 , 2024 , and in those other documents that Constellation has filed, or that Constellation and NewCo will file, with the U . S . Securities and Exchange Commission (the "SEC") . If any of these risks materialize or our assumptions prove incorrect, actual results could differ materially from the results implied by these forward - looking statements . The risks and uncertainties above are not exhaustive, and there may be additional risks that none of the Contracting Parties presently know or that they currently believe are immaterial that could also cause actual results to differ from those contained in the forward - looking statements . In addition, forward looking statements reflect relevant Contracting Parties' expectations, plans or forecasts of future events and views as of the date of these Presentation Materials . Each of the Contracting Parties anticipate that subsequent events and developments will cause those assessments to change . However, while the Contracting Parties may elect to update these forward - looking statements at some point in the future, each of the Contracting Parties specifically disclaim any obligation to do so . These forward - looking statements should not be relied upon as representing any of the Contracting Parties' assessments as of any date subsequent to the date of these Presentation Materials . Accordingly, undue reliance should not be placed upon the forward - looking statements . Use of Projections The projections, estimates and targets in these Presentation Materials are forward - looking statements that are based on assumptions that are inherently subject to significant uncertainties and contingencies, many of which are beyond any of the Contracting Party's control . See "Forward - Looking Statements" above . The assumptions and estimates underlying the projected, expected or target results are inherently uncertain and are subject to a wide variety of significant business, economic, regulatory, competitive, technological and other risks and uncertainties that could cause actual results to differ materially from those contained in such projections, estimates and targets . The projections are for illustrative purposes only and should not be relied upon as being necessarily indicative of future results . The assumptions and estimates underlying the prospective information are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the prospective information . While all projections, estimates and targets are necessarily speculative, each of the Contracting Parties believe that the preparation of prospective information involves increasingly higher levels of uncertainty the further out the projection, estimate or target extends from the date of preparation . Accordingly, there can be no assurance that prospective results are indicative of future performance or that actual results will not differ materially from any results presented or indicated in the prospective information . The inclusion of projections, estimates and targets in these Presentation Materials should not be regarded as an indication that any of the Contracting Parties, or their representatives, considered or consider the financial projections, estimates and targets to be a reliable prediction of future events . Neither the independent auditors of Constellation nor the independent registered public accounting firm or mining consultants or engineers of the Jindalee , NewCo or the Company has audited, reviewed, compiled or performed any procedures with respect to the projections for the purpose of their inclusion in these Presentation Materials, and accordingly, neither of them expressed an opinion or provided any other form of assurance with respect thereto for the purpose of these Presentation Materials . Non - GAAP Measures These Presentation Materials include certain financial measures not presented in accordance with United States generally accepted accounting principles ("GAAP") . These non - GAAP financial measures are not measures of financial performance in accordance with GAAP and may exclude items are significant in understanding and assessing the Company's financial results . Therefore, these measures should not be considered in isolation or as an alternative to net income, cash flows from operations or other measures of profitability, liquidity or performance under GAAP . You should be aware that the Company's presentation of these measures may not be comparable to similarly - titled measures used by other companies . Jindalee and the Company believe these non - GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to the Company's financial condition and results of operations . These Presentation Materials also include certain projections of non - GAAP financial measures . Due to the high variability and difficulty in making accurate forecasts and projections of some of the information excluded from these projected measures, together with some of the excluded information not being ascertainable or accessible, Jindalee and the Company are unable to quantify certain amounts that would be required to be included in the most directly comparable GAAP financial measures without unreasonable effort . Consequently, no disclosure of estimated comparable GAAP measures is included and no reconciliation of the forward - looking non - GAAP financial measures is included . Important Information and Where to Find It In connection with a Potential Business Combination, Constellation, Jindalee , the Company and NewCo are expected to prepare a registration statement on Form S - 4 (the "Registration Statement") to be filed with the SEC by NewCo , which will include preliminary and definitive proxy statements to be distributed to Constellation's shareholders in connection with Constellation's solicitation for proxies for the vote by Constellation's shareholders in connection with the Potential Business Combination and other matters as described in the Registration Statement, as well as the prospectus relating to the offer of the securities of NewCo in connection with the completion of the Potential Business Combination . After the Registration Statement has been filed and declared effective, Constellation will mail a definitive proxy statement and other relevant documents to its shareholders as of the record date to be established for voting on the Potential Business Combination . Constellation's shareholders and other interested persons are advised to read, once available, the preliminary proxy statement/prospectus and any amendments thereto, and the definitive proxy statement/prospectus, in connection with Constellation's solicitation of proxies for its extraordinary general meeting of shareholders to be held to approve, among other things, the Potential Business Combination, because these documents will contain important information about Constellation, Jindalee , the Company, NewCo and the Potential Business Combination .

The Pre - Feasibility Study, including the production target and the forecast financial information derived from the production target, referred to in these Presentation Materials (PFS) was first released to the ASX by Jindalee (ASX : JLL) on 19 November 2024 (PFS Announcement) . These Presentation Materials include summary excerpts from the PFS and do not purport to be all - inclusive or complete and should be read together with the PFS Announcement . Jindalee confirms that all material assumptions and technical parameters underpinning the production target and the forecast financial information derived from the production target, in the PFS Announcement continue to apply and have not materially changed . Shareholders and prospective investors should be aware that the PFS and these Presentation Materials do not include any forecast financial information in respect of the period after the initial 40 years of the Processing Schedule (post single commission and ramp up year), as the Contracting Parties cannot, at this stage, provide forecast financial information for that subsequent period . These Presentation Materials contain certain forward - looking statements, including forecast financial information . Forward - looking statements include but are not limited to statements concerning the Contracting Parties' current expectations, estimates, and projections about the industry in which Contracting Parties' operate and beliefs and assumptions regarding the Contracting Parties' future performance .

INVESTOR PRESENTATION \| 31 Risk Factors All references to the "company," "we," "us" or "our" refer to Jindalee Lithium Limited (" Jindalee ") and HiTech Minerals, Inc. (the "Company") and their consolidated entities prior to the Potential Business Combination, and for periods following the closing of the Potential Business Combination refer to NewCo as the combined company and its subsidiaries. The risks presented below are non - exhaustive descriptions of certain of the general risks related to the business of the Company, Constellation and NewCo and the Potential Business Combination, and such list is not exhaustive. The list below has been prepared solely for purposes of inclusion in these Presentation Materials and not for any other purpose. You should carefully consider these risks and uncertainties and should carry out your own diligence and consult with your own financial and legal advisors concerning the risks presented by an investment in the Company and the Potential Business Combination. Risks relating to the business of Constellation, Jindalee , the Company, the Potential Business Combination and the business of NewCo will be disclosed in future documents filed or furnished by Constellation or NewCo with the SEC, including the documents filed or furnished in connection with the Potential Business Combination. The risks presented in such filings will be consistent with SEC filings typically relating to a public company, including wit h respect to the business and securities of Jindalee , the Company, Constellation and NewCo and the Potential Business Combination, and may differ significantly from, and be more extensive than, those presented below. Risks Related to Our Business and Our Industry • Our business operates in the mining exploration and development industry. Our project is at the development stage, and there are no guarantees that development of the project into a mine will occur or that such development will result in the commercial extraction of mineral deposits. In addition, even if an economic mineral deposit is mined, we may not realize profits from our development activities in the short, medium or long term. • The economic viability of our project and its development remains subject to various factors, including, in the near term, the delivery of a definitive feasibility study which supports the project economics. To date, we have received a positive preliminary feasibility study, which has a lower level of confidence than a definitive feasibility study, but which has resulted in the definitive feasibility study being commissioned in respect of the project. The information presented in in these Presentation Materials is based solely on the preliminary feasibility study. • There can be no assurance that we will deliver a definitive feasibility study that supports the economic viability of the project moving forward or that the assumptions used in the definitive feasibility study to underpin the viability of the project (including, but not limited to, the prices of lithium carbonate) will remain true and correct in the future. • Our future performance is difficult to evaluate because we have a limited operating history in the mining, energy and resources sector, including in the battery metals industry. • Our long - term success will depend ultimately on implementing our business strategy and operational plan, as well as our ability to generate revenue, achieve and maintain profitability and develop positive cash flows from our mining activities. • Our business strategy is to develop the McDermitt Project to produce lithium domestically. Consequently, our growth depends upon the continued growth in lithium demand and in lithium - ion batteries. • The development and adoption of new battery technologies that rely on inputs other than lithium compounds could significantly impact our prospects and future revenues. • Our long - term success depends, in part, on our ability to negotiate and enter into sales agreements with, and deliver our product to, third party customers on commercially viable terms. There can be no assurance that we will be successful in securing such agreements. • Exchange rate fluctuations may materially affect our results of operations and financial condition. • We may seek to raise further funds through equity or debt financing, joint ventures, production sharing arrangements or other means. Consequently, we depend on our ability to successfully access the capital and financial markets. Any inability to access the capital or financial markets may limit our ability to fund our ongoing operations, execute our business plan or pursue investments that we may rely on for future growth. • Changes in technology or other developments could adversely affect demand for lithium compounds or result in preferences for substitute products. • Our possible future revenues will be mainly derived from the sale of lithium and magnesium products. Consequently, our success largely depends on the market price of lithium remaining higher than our costs of any future production (assuming successful exploration and development of the project). • When compared to many industrial and commercial operations, mining exploration and development projects are high risk and subject to uncertainties. Each mineral resource is unique and the nature of the mineralization, and the occurrence and grade of the lithium, as well as its behavior during mining, can never be wholly predicted. Our mineral resource estimates may be materially different from mineral quantities we may ultimately recover, our life - of - mine estimates may prove inaccurate and market price fluctuations and changes in operating and capital costs may render mineral resources uneconomic to mine. • The industry in which we operate is subject to domestic and global competition. We have no influence or control over the activities or actions of our competitors, which activities or actions may negatively affect the operating and financial performance of our projects and business. • If we fail to retain our key personnel or if we fail to attract additional qualified personnel, we may not be able to achieve our anticipated level of growth and our business could suffer. • Any failure by management to manage growth properly could have a material adverse effect on our business, operating results and financial condition. • Land reclamation and mine closure may be burdensome and costly. • Our success depends on developing and maintaining relationships with local communities and stakeholders. • We are exposed to general economic conditions and the fluctuations of interest and inflation rates may have an adverse effect on our business. • Our business may be adversely affected by force majeure events outside our control, including labor unrest, civil disorder, war, subversive activities or sabotage, extreme weather conditions, fires, floods, explosions or other catastrophes, epidemics or quarantine restrictions. Note: All amounts are in U.S.$ unless stated otherwise.

![](ex99-1_032.jpg)

INVESTOR PRESENTATION \| 32 Risk Factors Risks Related to Legal, Compliance and Regulations • If we receive federal monies, we could become subject to additional federal regulations. This could delay timing and increase costs. • We will be required to obtain governmental permits and approvals to conduct development and mining operations, a process which is often costly and time - consuming. There is no certainty that all necessary permits and approvals for our planned operations will be granted. • Our failure to comply with applicable anti - corruption, anti - bribery, anti - money laundering and similar laws and regulations could negatively impact our reputation and results of operations. • Our operations are subject to environmental, health and safety regulations, which could impose additional costs and compliance requirements, and we may face claims and liability for breaches, or alleged breaches, of such regulations and other applicable laws. • The impacts of climate change may adversely affect our operations and/or result in increased costs to comply with changes in regulations. • We face opposition from organizations that oppose mining which may disrupt or delay our mining projects. • The requirements of being a public company in the U.S. may strain our resources and divert management's attention, and the increases in legal, accounting and compliance expenses that will result from being a public company in the U.S. may be greater than we anticipate. • Our business could be adversely affected by trade tariffs or other trade barriers. • We are exposed to possible litigation risks, including mining permit disputes (including in respect of access and/or validity of tenure), environmental claims, occupational health and safety claims and employee claims. Further, we may be involved in disputes with other parties in the future that may result in litigation. Current or future litigation or administrative proceedings could have a material adverse effect on our business, financial condition and results of operations. Risks Related to Operations • The development of mining operations at the McDermitt Project is dependent on a number of factors, many of which are beyond our control. If we commence production at the project, our operations may be disrupted by a variety of risks and hazards that could have a material adverse effect on our future operating costs, financial condition and ability to develop and operate a mine. • The occurrence of significant events against which the Company may not be fully insured could have a material adverse effect on our business, financial condition and results of operations. • The threat of global economic, capital markets and credit disruptions pose risks to our business. Risks Related to Intellectual Property and Technology • Our failure to protect our intellectual property rights may undermine our competitive position, and litigation to protect our intellectual property rights may be costly. • We may need to defend ourselves against claims that we infringe, have misappropriated, or otherwise violate the intellectual property rights of others, which may be time - consuming and would cause us to incur substantial costs. • Any unauthorized access to, disclosure, or theft of personal information we gather, store, or use could harm our reputation and subject us to claims or litigation. • A failure of our information technology and data security infrastructure could adversely affect our business and operations. Risks Related to Future Performance and Resource Estimates • Actual capital costs, operating costs, production and economic returns may differ significantly from those we have anticipated and future development activities may not result in profitable mining operations. • Mining projects such as ours have no operating history on which to base estimates of future operating costs and capital requirements. Before operations commence, any projections we may produce are based upon estimates and assumptions made at the time they were prepared. If these estimates or assumptions prove to be incorrect or inaccurate, our actual operating results may differ materially from our forecasted results. • Our resource estimates may change significantly when new information or techniques become available. In addition, by their very nature, resource estimates are imprecise and depend to some extent on interpretations, which may prove to be inaccurate. As further information becomes available through additional fieldwork and analysis, our estimates, if any, are likely to change and these changes may result in a reduction in our resources. These changes may also result in alterations to our development and mining plans, which may, in turn, adversely affect our operations. Risk Related to Land Access • The Company may be required to negotiate access arrangements and pay compensation to land owners, local authorities, traditional land users and others who may have an interest in the area covered by tenure. The Company's ability to resolve access and compensation issues may have a negative impact on the future success and financial performance of the Company's operations. Risk Related to Tenures • In relation to tenures which the Company has an interest in or will in the future acquire, there may be areas of indigenous owned land. Where such rights exist, the ability of the Company to gain access to such tenures (through obtaining consent of any relevant landowner), or to progress such tenures from the exploration phase to the development and mining phases of operations may be adversely affected. Risk Related to Sediment - Hosted Lithium Deposit • The McDermitt Lithium Project is a sediment - hosted lithium deposit and the Company is not aware of any commercially operating lithium sediment presently anywhere in the world. Jindalee has completed a comprehensive metallurgical testwork program as part of the McDermitt Lithium Project Pre - Feasibility Study in November 2024, encompassing all major processing stages from beneficiation through to the production of battery - grade lithium carbonate. While the results of this work provide an increased level of confidence in the technical viability of the proposed flowsheet, further optimisation and pilot - scale testing will be required to finalise process design parameters and confirm the scalability of the flowsheet to commercial production. There remains no assurance that lithium production can ultimately be achieved on an economically viable basis or at all. Note: All amounts are in U.S.$ unless stated otherwise.

INVESTOR PRESENTATION \| 33 Risk Factors Risks Related to Constellation and the Potential Business Combination • Constellation, Jindalee , the Company and NewCo may not enter into a binding or definitive agreement relating to the Potential Business Combination, and even if they do, the conditions to complete the Potential Business Combination may not be satisfied or may be waived. • In order for the Potential Business Combination to close, in addition to other regulatory and governmental approvals that must be obtained by each of Constellation, Jindalee , the Company and NewCo , among others, the shareholders of Jindalee will be required to approve the transaction on the terms set out in the definitive agreement in accordance with Australian corporate law and the listing rules of the Australian Securities Exchange. There can be no guarantee that such approval will be obtained. • Constellation Sponsor LP (the "Sponsor") and certain Constellation shareholders affiliated with the Sponsor have agreed to vote in favor of the Potential Business Combination, regardless of how Constellation's public shareholders vote. • The Sponsor, certain members of the Constellation Board and management have interests in the Potential Business Combination that are different from or are in addition to public shareholders, which may include direct or indirect ownership of Constellation's founder shares and/or private placement warrants, each of which will lose their value if an initial business combination is not consummated. • Constellation's Board has potential conflicts of interest in recommending that shareholders vote in favor of approval of the Potential Business Combination proposal and approval of the other proposals in connection therewith. • Our shareholders and Constellation's shareholders will experience dilution as a consequence of the Potential Business Combination. • Future resales of NewCo's outstanding shares may cause the market price of its securities to drop significantly, even if NewCo's business is doing well. • We cannot assure you that NewCo's or Constellation's stock price will not decline or not be subject to significant volatility. • The ability of Constellation's remaining public shareholders to exercise redemption rights with respect to Constellation's outstanding public shares could increase the possibility that the Potential Business Combination would limit NewCo's public float following the Potential Business Combination. • We and Constellation will be subject to business uncertainties and contractual restrictions once documentation for the Potential Business Combination is executed. • Constellation cannot assure you that its due diligence review of our business has identified all material issues or risks associated with us, our business, or the industry in which we operate. Additional information may later arise in connection with the preparation of the registration statement and proxy materials or after completion of the Potential Business Combination. If Constellation's due diligence investigation of our business was inadequate, then stockholders of Constellation following the Potential Business Combination could lose some or all of their investment. • There can be no assurance that NewCo following the closing of the Potential Business Combination will be able to comply with the continued listing standards of Nasdaq. Further, there is no guarantee that an active and liquid public market for NewCo's shares will develop. • If, following the Potential Business Combination, securities or industry analysts do not publish or cease publishing research or reports about NewCo , its business, or its market, or if they change their recommendations regarding NewCo's shares adversely, then the price and trading volume of NewCo's shares could decline. • NewCo may be unable to obtain additional financing to fund its operations or growth. • Constellation is an "emerging growth company" within the meaning of the Securities Act, and we believe that NewCo will qualify as an emerging growth company following the Potential Business Combination. Constellation and NewCo intend to take advantage of certain exemptions from disclosure requirements available to emerging growth companies, which could make their securities less attractive to investors and may make it more difficult to compare performance with other public companies. • We and Constellation will incur significant transaction costs in connection with the Potential Business Combination. • Following the Potential Business Combination, a small number of shareholders will own a substantial majority of our shares, giving them material influence over the outcome of matters requiring a shareholder vote, including the election of directors and the approval of material matters and their interests may not align with the interest of other shareholders. • In connection with the Potential Business Combination, Constellation's sponsor and its officers, directors, advisors or their respective affiliates may elect to purchase Class A ordinary shares from public shareholders, which may reduce the public float of NewCo's shares. • Other risks and uncertainties set forth in the section entitled "Risk Factors" and "Cautionary Note Regarding Forward - Looking Statements" in the registration statement on Form S - 4 to be filed in connection with the Potential Business Combination or in other documents filed by Constellation and NewCo with the SEC. Note: All amounts are in U.S.$ unless stated otherwise.
