The disclosure contained in Item 1.01 of this Current Report on Form 8-K is incorporated by reference into this Item 2.03.

Item 8.01 Other Events.

On June 21, 2023, Global Hydrogen issued an unsecured promissory note (the “Glatt Note”) to Carter Glatt, Dune’s Chief Executive Officer and Director, which provides for borrowings from time to time of up to an aggregate of $250,000 that may be drawn by Global Hydrogen and used for working capital purposes and to pay expenses related to the Business Combination. The Glatt Note does not bear interest and is payable on the earlier of December 31, 2023 and the completion of the Business Combination. The Glatt Note is subject to customary events of default, the occurrence of any of which automatically triggers the unpaid principal balance of the Glatt Note and all other sums payable with regard to the Glatt Note to become immediately due and payable.

On June 21, 2023, Global Hydrogen borrowed $83,950 under the Glatt Note.

The foregoing summary of the Glatt Note is qualified in its entirety by reference to the Glatt Note, a copy of which is filed as Exhibit 99.1 hereto, and which is incorporated by reference into this Item 8.01.

Cautionary Note Regarding Forward-Looking Statements

This Current Report on Form 8-K contains certain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements may be identified by the use of words such as “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “might,” “plan,” “possible,” “potential,” “predict,” “project,” “should,” “would,” “will,” “shall,” “seek,” “result,” “become,” “target” or other 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 a statement is not forward looking. Indications of, and guidance or outlook on, future earnings, dividends or financial position or performance are also forward-looking statements. These forward-looking statements include, but are not limited to: (1) references with respect to the anticipated benefits of the proposed Business Combination and anticipated closing timing; (2) the anticipated capitalization and enterprise value of the combined company following the consummation of the proposed Business Combination; (3) current and future potential commercial and customer relationships; and (4) anticipated demand for the combined company’s product and service offerings. These statements are based on various assumptions, whether or not identified in this Current Report on Form 8-K, and on the current expectations of Dune’s and Global Hydrogen’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.

These forward-looking statements involve significant risks and uncertainties that could cause the actual results to differ materially, and potentially adversely, from those expressed or implied in the forward-looking statements. Forward-looking statements are predictions, projections and other statements about future events that are based on current expectations and assumptions and, as a result, are subject to risks and uncertainties. Most of these factors are outside Dune’s and Global Hydrogen’s control and are difficult to predict. Factors that may cause such differences include, but are not limited to: (i) the occurrence of any event, change, or other circumstances that could give rise to the termination of the definitive Unit Purchase Agreement dated May 14, 2023 governing the Business Combination between Dune and Global Hydrogen (the “Purchase Agreement”); (ii) the outcome of any legal proceedings that may be instituted against Dune and Global Hydrogen following the announcement of the Purchase Agreement and the transactions contemplated thereby; (iii) the inability of the parties to timely or successfully complete the proposed Business Combination, including due to failure to obtain approval of the stockholders of Dune, redemptions by Dune’s stockholders, certain regulatory approvals or the satisfaction of other conditions to closing in the Purchase Agreement; (iv) risks relating to the uncertainty of the projected financial information with respect to Global Hydrogen; (v) the occurrence of any event, change or other circumstance that could give rise to the termination of the Purchase Agreement or could otherwise cause the transaction to fail to close; (vi) the impact of the COVID-19 pandemic on Global Hydrogen’s business and/or the ability of the parties to complete the proposed Business Combination; (vii) the inability to maintain the listing of Dune’s shares on the Nasdaq Stock Market following the proposed Business Combination; (viii) the risk that the proposed Business Combination disrupts current plans and operations as a result of the announcement and consummation of the proposed Business Combination; (ix) the ability to recognize the anticipated benefits of the proposed Business Combination, which may be affected by, among other things, competition, the ability of Global Hydrogen to grow and manage growth profitably, sell and expand its product and service offerings, implement its growth strategy and retain its key employees; (x) risks relating to Global Hydrogen’s operations and business, including the combined company’s ability to raise financing, hire employees, secure supplier, customer and other commercial contracts, obtain licenses and information technology and protect itself against cybersecurity risks; (xi) intense competition and competitive pressures from other companies worldwide in the industries in which the combined company will operate; (xii) litigation and the ability to adequately protect the combined company’s intellectual property rights; (xiii) costs related to the proposed Business Combination; (xiv) changes in applicable laws or regulations; and (xv) the possibility that Global Hydrogen or Dune may be adversely affected by other economic, business and/or competitive factors. The foregoing list of factors is not exhaustive, and there may be additional risks that neither Dune nor Global Hydrogen presently know or that Dune and Global Hydrogen currently believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. Additional information concerning certain of these and other risk factors is contained in Dune’s most recent filings with the SEC, including Dune’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022 and in those documents that Dune has filed, or will file, with the SEC. These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained herein. In addition, forward-looking statements reflect Dune’s and Global Hydrogen’s expectations, plans or forecasts of future events and views as of the date of this Current Report on Form 8-K. Dune and Global Hydrogen anticipate that subsequent events and developments will cause Dune’s and Global Hydrogen’s assessments to change. All subsequent written and oral forward-looking statements concerning Dune and Global Hydrogen, the transactions related to the proposed Business Combination or other matters attributable to Dune, Global Hydrogen or any person acting on their behalf are expressly qualified in their entirety by the cautionary statements above. Readers are cautioned not to place undue reliance upon any forward-looking statements, which speak only as of the date made. While Dune and Global Hydrogen may elect to update these forward-looking statements at some point in the future, each of Dune and Global Hydrogen expressly disclaims any obligations or undertaking to release publicly any updates or revisions to any forward-looking statements contained herein to reflect any change in their expectations with respect thereto or any change in events, conditions or circumstances on which any statement is based, except as required by law. These forward-looking statements should not be relied upon as representing Dune’s and Global Hydrogen’s assessments as of any date subsequent to the date of this Current Report on Form 8-K. Accordingly, undue reliance should not be placed upon the forward-looking statements.
