Cautionary Note Regarding Forward Looking Statements
Certain statements included in this Current Report 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, projections of market opportunity, anticipated size of the lithium resources, expected support from Jindalee Lithium Limited (“Jindalee”), expected NPV or post-tax IRR, and planned production per year; (2) references with respect to the anticipated benefits of the Business Combination and the projected future financial and operational performance of PubCo following the Business Combination, which may be affected by, among other things, competition, the ability of PubCo to grow and manage growth profitably, maintain relationships and retain its management and key employees; (3) the sources and uses of cash of the Business Combination; (4) the anticipated capitalization and enterprise value of PubCo following the consummation of the Business Combination; (5) statements regarding PubCo’s operations following the Business Combination; (6) the amount of redemption requests made by CSTA’s public shareholders; (7) current and future potential commercial relationships; (8) plans, intentions or future operations of PubCo or HiTech, 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 PubCo or CSTA to issue equity or equity-linked securities in the future or raise additional capital in a PIPE financing; (10) the outcome of any legal proceedings that may be instituted against Contracting Parties (as defined below); (11) changes to the proposed structure of the 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 Business Combination; (13) the risk that the Business Combination disrupts current plans and operations of CSTA, PubCo or HiTech; (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 Business Combination and the ability of the parties to successfully consummate the Business Combination. These statements are based on various assumptions, whether or not identified in the Current Report, 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 investor presentation published on the date hereof and those set forth in the section entitled “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements and Risk Factor Summary” in CSTA’s Annual Report on Form 10-K for the year ended December 31, 2025 (the “Annual Report”), and in those other documents that CSTA has filed, or that PubCo and CSTA will file, with the Securities and Exchange Commission (“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 the Current Report. 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 Current Report. Accordingly, undue reliance should not be placed upon the forward-looking statements.

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 investor presentation published on April 9, 2026 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 (the “Annual Report”), and in those other documents that Constellation has filed, or that the Company and Constellation will file, with 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 this communication. 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 this communication. Accordingly, undue reliance should not be placed upon the forward-looking statements.
