CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Supplement contains includes “forward-looking statements” within the meaning of the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995 and within the meaning of Section 27a of the Securities Act and Section 21E of the Exchange Act. Any actual results may differ from expectations, estimates and projections presented or implied and, consequently, you should not rely on these forward-looking statements as predictions of future events. Words such as “expect,” “estimate,” “project,” “budget,” “forecast,” “anticipate,” “intend,” “plan,” “may,” “will,” “could,” “should,” “believes,” “predicts,” “potential,” “continue,” and similar expressions are intended to identify such forward-looking statements. These forward-looking statements include, without limitation, statements regarding the proposed business combination and the expectation that Rezolve will re-register as a public limited liability company after the Closing. These forward-looking statements are subject to a number of risks and uncertainties, including, among others, (1) the occurrence of any event, change or other circumstances that could give rise to the termination of the proposed business combination; (2) the outcome of any legal proceedings that may be instituted against Armada, Rezolve Limited, Rezolve or others following the announcement of the proposed business combination and any definitive agreements with respect thereto; (3) the inability to complete the proposed business combination due to the failure to obtain approval of the stockholders of Armada or shareholders of Rezolve Limited or Rezolve, or to satisfy other conditions to closing of the transactions contemplated under and in connection with the Business Combination Agreement; (4) the ability to meet stock exchange listing standards as a condition to closing of the business combination or following the consummation of proposed business combination; (5) the risk that the proposed business combination disrupts current plans and operations of Armada, Rezolve Limited or Rezolve as a result of the announcement and consummation of the proposed business combination; (6) the ability to recognize the anticipated benefits of the proposed business combination, which may be affected by, among other things, competition, the ability of the combined company to grow and manage growth profitably, and retain its management and key employees; (7) costs related to the proposed business combination; (8) changes in applicable laws or regulations and delays in obtaining, adverse conditions contained in, or the inability to obtain regulatory approvals required to complete the proposed business combination; (9) weakness in the economy, market trends, uncertainty and other conditions in the markets in which Rezolve Limited or Rezolve operate, and other factors beyond their control, such as inflation or rising interest rates; (10) the possibility that Armada, Rezolve Limited, Rezolve or the combined company may be adversely affected by other economic, business, and/or competitive factors; (11) the ability of existing investors to redeem and the level of redemptions; and (12) additional risks, including those to be included under the header “Risk Factors” in the Proxy Statement/Prospectus and those included under the header “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements” in Armada’s Annual Report on Form 10-K for the year ended September 30, 2023 and the Quarterly Reports on Form 10-Q filed by Armada for the quarterly periods ended December 31, 2023 and March 31, 2024.

If any of these risks materialize or Armada’s, Rezolve Limited’s or Rezolve’s assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. There may be additional risks that none of Armada, Rezolve Limited or Rezolve presently know or that Armada, Rezolve Limited and Rezolve 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 Armada’s, Rezolve Limited’s and/or Rezolve’s expectations, plans or forecasts of future events and views as of the date of this press release. Armada, Rezolve Limited and Rezolve anticipate that subsequent events and developments will cause Armada, Rezolve Limited’s and Rezolve’s assessments to change. However, while Armada, Rezolve Limited and Rezolve may elect to update these forward-looking statements at some point in the future, each of Armada, Rezolve Limited, Rezolve and Rezolve Merger Sub specifically disclaim any obligation to do so, unless required by applicable law. These forward-looking statements should not be relied upon as representing Armada’s, Rezolve Limited’s and Rezolve’s assessments as of any date subsequent to the date of this press release. Accordingly, undue reliance should not be placed upon the forward-looking statements.
