3 yForward-Looking Statements This Presentation includes “forward-looking statements” within the meaning of the “safe harbor” provisions of the United States Private Securities Litigation Reform Act of 1995. yForward-looking statements generallyyFE relate to future events or Parabellum’s or the CompanyyFYMMSN=Es/Holdco’s future financial or operating performance. In some cases, yyFEou can identifyyFE forward-looking statements byyFE terminologyyFE such as “mayyFE,” “should,” “expect,” “intend,” “will,” “estimate,” “anticipate,” “believe,” “predict,” “seek,” “target,” “project,” “forecast,” “plan,” “potential” or “continue”, or the negatives of these terms or variations of them or similar terminologyyFE or expressions that predict or indicate future events or trends or that are not statements of historical matters. These forward-looking statements include, but are not limited to, statements regarding projections, estimates and forecasts of future revenue and other financial and performance metrics, and projections of market opportunityyFE and market share, as well as statements regarding the Proposed Business Combination and the expected timing of completion thereof. These forward-looking statements are (i) based on various assumptions, whether or not identified in this Presentation, and on the current expectations of management of the CompanyyFE, (ii) not predictions of actual performance, (iii) provided for illustrative purposes onlyyFE and (iv) not intended to serve as, and must not be relied on byyFE anyyFE investor as, a guarantee, an assurance, a prediction or a definitive statement of fact or probabilityyFE or anyyFE representation byyFE anyyFE person that the forward-looking statements set forth in this Presentation or the results contemplated therebyyFE will be achieved. Actual events and circumstances are difficult or impossible to predict and will differ from assumptions. ManyyFE actual events and circumstances are beyyFEond the control of the CompanyyFE/Holdco. These forward-looking statements are subject to a number of risks, uncertainties, and other factors, including, but not limited to, (a) changes in domestic and foreign business, market, financial, political, and legal conditions; (b) the inabilityyFE of the parties to successfullyyFE or timelyyFE consummate the Proposed Business Combination, including the risk that anyyFE required regulatoryyFE approvals are not obtained, are delayyFEed or are subject to unanticipated conditions that could adverselyyFE affect the combined companyyFE or the expected benefits of the Proposed Business Combination or that the approval of stockholders is not obtained; (c) failure to realize the anticipated benefits of the Proposed Business Combination; (d) risks relating to the uncertaintyyFE of the projected financial information with respect to the CompanyyFE; (e) reductions in discretionaryyFE consumer spending, including as a result of global and regional economic downturns; (f) risks related to the rollout of the CompanyyFYMMSN=Es/Holdco’s business and the timing of expected business milestones, and to relationships with customers, retailers and distributors, and the use of third-partyyFE manufacturers; (g) the effects of competition on the CompanyyFYMMSN=Es/Holdco’s future business; (h) disruption of the CompanyyFYMMSN=Es relationships with its customers, suppliers, business partners and others resulting from the announcement of the Proposed Business Combination; (i) the amount of redemption requests made byyFE Parabellum’s public stockholders in connection with the Proposed Business Combination; (j) the abilityyFE of Parabellum or the combined companyyFE to issue equityyFE or equityyFE-linked securities in connection with the Proposed Business Combination or in the future; (k) that, if the Proposed Business Combination’s benefits do not meet the expectations of investors or securities analyyFEsts, the market price of Parabellum’s securities or, following the consummation of the Proposed Business Combination, the combined companyyFYMMSN=Es securities, mayyFE decline; (l) that the valuation ascribed to the combined companyyFE mayyFE not be indicative of the price that will prevail in the trading market following the consummation of the Proposed Business Combination; (m) that, if an active market for the combined companyyFYMMSN=Es securities develops and continues, the trading price of the combined companyyFYMMSN=Es securities following the Proposed Business Combination could be volatile and subject to wide fluctuations in response to various factors, which could contribute to the loss of all or part of yyFEour investment; (n) that the combined companyyFE mayyFE be required to take write-downs or write-offs, or be subject to restructuring, impairment or other charges that could have a significant negative effect on the combined companyyFYMMSN=Es financial condition, results of operations and the price of its common stock, which could cause yyFEou to lose some or all of yyFEour investment; (o) that the combined companyyFE will incur significant transaction costs in connection with the Proposed Business Combination; (p) that legal proceedings in connection with the Proposed Business Combination, the outcomes of which are uncertain, could delayyFE or prevent the completion of the Proposed Business Combination; (q) that following the consummation of the Proposed Business Combination, the combined companyyFE will incur significant increased expenses and administrative burdens as a public companyyFE, which could have an adverse effect on its business, financial condition and results of operations; and (r) that the Proposed Business Combination or the post-combination companyyFE mayyFE be materiallyyFE adverselyyFE affected byyFE COVID-19. If anyyFE of these risks, uncertainties or other factors materialize or the CompanyyFYMMSN=Es assumptions prove incorrect, actual results could differ materiallyyFE from the results implied byyFE these forward-looking statements. There mayyFE be additional risks that neither Parabellum nor Holdco nor the CompanyyFE presentlyyFE know or that theyyFE currentlyyFE believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements contained in this Presentation. In addition, forward looking statements in this Presentation speak onlyyFE as of the date of this Presentation. While Parabellum, Holdco and the CompanyyFE mayyFE elect to update these forward-looking statements at some point in the future, Parabellum, Holdco and the CompanyyFE specificallyyFE disclaim anyyFE obligation to do so. These forward-looking statements should not be relied upon as representing Parabellum’s, Holdco’s and the CompanyyFYMMSN=Es assessments as of anyyFE date subsequent to the date of this Presentation. AccordinglyyFE, undue reliance should not be placed upon these forward-looking statements. Information and opinions expressed in this Presentation were obtained from sources believed to be reliable and in good faith, and no representation or warrantyyFE, express or implied, is made as to the accuracyyFE or completeness thereof. This Presentation contains preliminaryyFE information onlyyFE, is subject to change at anyyFE time and is not, and should not be assumed to be, complete or constitute all the information necessaryyFE to adequatelyyFE make an informed decision regarding yyFEour engagement with the CompanyyFE, Holdco or Parabellum. © yEnOcean 2022 | Sustainable IoT

4 Use of Projections This Presentation contains references to financial forecasts with respect to the CompanyyFYMMSN=Es projected financial results, including for the CompanyyFYMMMN=Es fiscal yyFEear 2023. The CompanyyFYMMMN=Es independent auditors have not audited, reviewed, compiled or performed anyyFE procedures with respect to the projections for the purpose of their inclusion in this Presentation, and accordinglyyFE, theyyFE did not express an opinion or provide anyyFE other form of assurance with respect thereto for the purpose of this Presentation. These projections should not be relied upon as being necessarilyyFE indicative of future results. The assumptions and estimates underlyyFEing the prospective financial information are inherentlyyFE uncertain and are subject to a wide varietyyFE of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materiallyyFE from those contained in the prospective financial information. See the “yForward-Looking Statements” paragraph above. AccordinglyyFE, there can be no assurance that the prospective results are indicative of the future performance of the CompanyyFE or that actual results will not differ materiallyyFE from those presented in the prospective financial information. Inclusion of the references to the prospective financial information in this Presentation should not be regarded as a representation byyFE anyyFE person that the results contained in the prospective financial information will be achieved. There are numerous factors related to the markets in general or the implementation of anyyFE operational strategyyFE that cannot be fullyyFE accounted for with respect to the projections herein. AnyyFE targets or estimates are therefore subject to a number of important risks, qualifications, limitations and exceptions that could materiallyyFE and adverselyyFE affect Parabellum and the CompanyyFYMMSN=Es performance. Moreover, actual events are difficult to project and often depend upon factors that are beyyFEond the control of Parabellum and the CompanyyFE and its affiliates. “ Adjusted yEBITDA ” means net income (loss) before interest expense, income tax expense (benefit), depreciation and amortization expense, one-time expenses related to the Proposed Business Combination and stock-based compensation expense and is a financial measure not presented in accordance with US GAAP. It excludes items that are significant in understanding and assessing the CompanyyFYMMSN=Es financial results and the effect of the Proposed Business Combination. Therefore, management does not consider Adjusted yEBITDA in isolation or as an alternative to net income, cash flows from operations or other measures of profitabilityyFE, liquidityyFE or performance under German GAAP. However, the CompanyyFE believes that Adjusted yEBITDA provides useful information to management and investors regarding certain financial and business trends relating to the CompanyyFYMMSN=Es financial condition and results of operations. The CompanyyFE believes that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends in and in comparing the CompanyyFYMMSN=Es financial measures with other similar companies, manyyFE of which present similar non-GAAP financial measures to investors. The principal limitation of this non-GAAP measure is that it excludes significant expenses and income that are required byyFE US GAAP to be recorded in the CompanyyFYMMSN=Es financial statements. AdditionallyyFE, Adjusted yEBITDA is subject to inherent limitations as it reflects the exercise of judgments byyFE management about which expense and income are excluded or included in determining this non-GAAP financial measure. © yEnOcean 2022 | Sustainable IoT

Risk yFactors © yEnOcean 2022 | Sustainable IoT All references to “the CompanyyFE,” “we,” “us” or “our” refer to the business, yEnOcean GmbH (together with its subsidiaries), and to “Holdco” refers to yEnOcean Holdings B.V. The risks presented below are certain of the general risks related to the business of the CompanyyFE, Parabellum Acquisition Corp. (“SPAC”), and the proposed transactions between the CompanyyFE, Holdco and SPAC (the “Proposed Business Combination”), and such list is not exhaustive. The list below has been prepared solelyyFE for purposes of the private placement transaction, and solelyyFE for potential private placement investors, and not for anyyFE other purpose. You should carefullyyFE consider these risks and uncertainties, together with the information in the CompanyyFYMMSN=Es consolidated financial statements and related notes and should carryyFE out yyFEour own diligence and consult with yyFEour own financial and legal advisors concerning the risks and suitabilityyFE of an investment in this offering before making an investment decision. Risks relating to the business of the CompanyyFE/Holdco will be disclosed in future documents filed or furnished byyFE Holdco, the CompanyyFE and/or SPAC with the United States Securities and yExchange Commission (the “SyEC”), including the documents filed or furnished in connection with the proposed transactions between Holdco, the CompanyyFE and SPAC. The risks presented in such filings will be consistent with those that would be required for a public companyyFE in their SyEC filings, including with respect to the business and securities of Holdco, the CompanyyFE and SPAC and the proposed transactions between Holdcho, the CompanyyFE and SPAC, and mayyFE differ significantlyyFE from, and be more extensive than, those presented below. Risks Related to our Business and IndustryyFE: • We have a historyyFE of generating net losses, and if we are unable to achieve adequate revenue growth while our expenses increase, we mayyFE not achieve or maintain profitabilityyFE in the future. • If we fail to manage our growth effectivelyyFE or to sustain our revenue growth, we mayyFE be unable to execute our business plan, maintain customer satisfaction or adequatelyyFE address competitive challenges. • Members of the CompanyyFYMMSN=Es management have limited experience in operating a public companyyFE. The requirements of being a public companyyFE mayyFE strain our resources and divert management’s attention, and the increases in legal, accounting and compliance expenses that will result from being a public companyyFE mayyFE be greater than we anticipate. • If we do not attract new customers and increase our customers’ use of our products and services, our business will suffer. • Our limited operating historyyFE, especiallyyFE with the edge computing solutions business acquired from Renesas yElectronics Corporation, makes it difficult to evaluate our current business and future prospects and mayyFE increase the risk that we will not be successful. • We generate a significant portion of our revenue from our largest customers, and the loss or decline in revenue from anyyFE of these customers could harm our business, results of operations, and financial condition. • If we fail to continue to improve and enhance the functionalityyFE, performance, reliabilityyFE, design and securityyFE in a manner that responds to our customers’ evolving needs, our business mayyFE be adverselyyFE affected. • Our brand is integral to our success. If we fail to effectivelyyFE maintain, promote, and enhance our brand, our business and competitive advantage mayyFE be harmed. • We are dependent on the continued services and performance of our senior management and other keyyFE employyFEees, the loss of anyyFE of whom could adverselyyFE affect our business, operating results, and financial condition. • Our abilityyFE to recruit, retain, and develop qualified personnel is critical to our success and growth. • If our technical and maintenance support services are not satisfactoryyFE to our customers, theyyFE mayyFE not buyyFE future products, which could materiallyyFE and adverselyyFE affect our future results of operations and financial condition. • AnyyFE future litigation against us could be costlyyFE and time-consuming to defend. • Our pricing decisions and pricing models mayyFE adverselyyFE affect our abilityyFE to attract new customers and retain existing customers. 27

Risk yFactors (continued) © yEnOcean 2022 | Sustainable IoT Risks Related to our Business and IndustryyFE (continued): • If our technical and maintenance support services are not satisfactoryyFE to our customers, theyyFE mayyFE not buyyFE future products, which could materiallyyFE and adverselyyFE affect our future results of operations and financial condition. • Increases in labor and component costs, and supplyyFE-chain delayyFEs could adverselyyFE affect results of operations. • We transmit and store personal information of our customers and consumers. If the securityyFE of this information is compromised, our reputation mayyFE be harmed, and we mayyFE be exposed to liabilityyFE and loss of business. • We are subject to stringent and changing privacyyFE laws, regulations and standards, and contractual obligations related to data privacyyFE and securityyFE. Our actual or perceived failure to complyyFE with such obligations could harm our reputation, subject us to significant fines and liabilityyFE, or adverselyyFE affect our business. • SecurityyFE breaches, denial of service attacks, or other hacking and phishing attacks on our syyFEstems or the syyFEstems with which our platform integrates could harm our reputation or subject us to significant liabilityyFE, and adverselyyFE affect our business and financial results. • Interruptions or performance problems associated with our technologyyFE mayyFE adverselyyFE affect our business and operating results. • Defects, errors, or vulnerabilities in our hardware, software or other technologyyFE syyFEstems and those of third-partyyFE technologyyFE providers could harm our reputation and brand and adverselyyFE impact our business, financial condition, and results of operations. • We mayyFE require additional capital, which additional financing mayyFE result in restrictions on our operations or substantial dilution to our stockholders, to support the growth of our business, and this capital might not be available on acceptable terms, if at all. • Our business is highlyyFE competitive. We mayyFE not be able to compete successfullyyFE against current and future competitors. • The estimates of market opportunityyFE and forecasts of market growth included in this presentation mayyFE prove to be inaccurate, and even if the market in which we compete achieves the forecasted growth, our business could fail to grow at similar rates, if at all. Risks Related to the COVID-19 Pandemic: • The ongoing COVID-19 pandemic has adverselyyFE impacted and mayyFE continue to adverselyyFE impact our business, financial condition, and results of operations. • The COVID-19 pandemic has resulted in global supplyyFE chain shortages, that we expect to continue in the foreseeable future, which could have a material adverse effect on our business, results of operations, and financial results. 28

Risk yFactors (continued) © yEnOcean 2022 | Sustainable IoT Risks Related to our Intellectual PropertyyFE: • If we fail to adequatelyyFE protect our intellectual propertyyFE rights, our competitive position could be impaired and we mayyFE lose valuable assets, generate reduced revenue and become subject to costlyyFE litigation to protect our rights. • We mayyFE be subject to claims byyFE third parties of intellectual propertyyFE infringement. • We use open-source software in our platform, which could negativelyyFE affect our abilityyFE to sell our services or subject us to litigation or other actions. • Third-partyyFE claims that we are infringing intellectual propertyyFE, whether successful or not, could subject us to costlyyFE and time-consuming litigation or expensive licenses, and our business could be adverselyyFE affected. • Our intellectual propertyyFE applications, including patent applications, mayyFE not be approved or granted or mayyFE take longer than expected to be approved, which mayyFE have a material adverse effect on our abilityyFE to prevent others from commerciallyyFE exploiting products similar to ours. • In addition to patented technologyyFE, we relyyFE on trade secrets, designs, experiences, work flows, data processes, software and know-how. General Risks • Downturns or volatilityyFE in general economic conditions could have a material adverse effect on the CompanyyFYMMSN=Es business, financial condition, results of operations and liquidityyFE. • IndustryyFE consolidation mayyFE result in increased competition, which could result in a reduction in revenue. • The CompanyyFE depends on growth in the end markets that use its products. AnyyFE slowdown in the growth of these end markets could adverselyyFE affect its financial results. • The CompanyyFE is dependent on a limited number of distributors and end customers. The loss of, or a significant disruption in the relationships with anyyFE of these distributors or end customers, could significantlyyFE reduce the CompanyyFYMMSN=Es revenue and adverselyyFE impact the CompanyyFYMMSN=Es operating result. A significant portion of the CompanyyFYMMSN=Es chip supplies are generated through customers in Taiwan which subjects the CompanyyFE to risks associated with supplier interest and governmental or regulatoryyFE changes as well as geopolitical developments, particularlyyFE related to Taiwan and China. • If the CompanyyFE fails to accuratelyyFE anticipate and respond to rapid technological change in the industries in which the CompanyyFE operates, the CompanyyFYMMSN=Es abilityyFE to attract and retain customers could be impaired and its competitive position could be harmed. • The CompanyyFYMMMN=Es competitive position could be adverselyyFE affected if it is unable to meet customers’ or device manufacturers’ qualityyFE requirements. • If the CompanyyFE is unable to expand or further diversifyyFE its customer base, its business, financial condition, and results of operations could suffer. • If the CompanyyFYMMSN=Es products do not conform to, or are not compatible with, existing or emerging industryyFE standards, demand for its products mayyFE decrease, which in turn would harm the CompanyyFYMMSN=Es business and operating results. • The CompanyyFE is subject to risks and uncertainties associated with international operations, which mayyFE harm its business. • The CompanyyFYMMMN=Es companyyFE culture has contributed to its success and if the CompanyyFE cannot maintain this culture as it grows, its business could be harmed. 29

Risk yFactors (continued) © yEnOcean 2022 | Sustainable IoT General Risks (continued) • The CompanyyFE mayyFE not be able to effectivelyyFE manage its growth and mayyFE need to incur significant expenditures to address the additional operational and control requirements of its growth, either of which could harm the CompanyyFYMMSN=Es business and operating results. • Shifts in the CompanyyFYMMSN=Es product mix or customer mix mayyFE result in declines in gross margin. • The CompanyyFE mayyFE from time-to-time desire to exit certain programs or businesses, or to restructure its operations, but mayyFE not be successful in doing so. • The CompanyyFE mayyFE pursue mergers, acquisitions, investments and joint ventures, which could divert its management’s attention or otherwise disrupt its operations and adverselyyFE affect its results of operations. • The CompanyyFE mayyFE not be able to convert its pipeline or orders in backlog into revenue. • The CompanyyFE mayyFE not manage its growth effectivelyyFE. • Our forecasts and projections are based on assumptions, analyyFEses and internal estimates developed byyFE our management. If these assumptions, analyyFEses or estimates prove to be incorrect or inaccurate, our actual operating results mayyFE differ materiallyyFE from those forecasted or projected. • The market adoption of our product is evolving and mayyFE develop more slowlyyFE or differentlyyFE than we expect. Our future success depends on the growth and expansion of these markets and our abilityyFE to adapt and respond effectivelyyFE to evolving markets. • Interruption or failure of our information technologyyFE and communication syyFEstems could impact our abilityyFE to effectivelyyFE provide our products and services. • We are subject to cyyFEbersecurityyFE risks to operational syyFEstems, securityyFE syyFEstems, infrastructure, integrated software in our products and customer data processed byyFE us or third-partyyFE vendors or suppliers and anyyFE material failure, weakness, interruption, cyyFEber event, incident or breach of securityyFE could hinder the effective operation of our business. Stock and Capitalization Risks • The CompanyyFE has a historyyFE of losses and mayyFE incur significant expenses and continuing losses for the foreseeable future. • The market price of the combined companyyFYMMSN=Es common stock mayyFE be highlyyFE volatile. • The CompanyyFYMMSN=Es operating results mayyFE have significant period-to-period fluctuations, which would make it difficult to predict our future performance. • Raising additional funds byyFE issuing securities mayyFE cause dilution to existing stockholders or restrict the combined companyyFYMMSN=Es operations. • The combined companyyFE does not intend to payyFE cash dividends. ConsequentlyyFE, anyyFE gains from an investment in its securities will likelyyFE depend on whether the price of the common stock increases. • The combined companyyFYMMSN=Es executive officers and directors will own a significant percentage of the common stock and could exert significant influence over matters requiring stockholder approval, including takeover attempts. • yFailure to meet the maintenance criteria of the stock exchange mayyFE result in the delisting of the combined companyyFYMMSN=Es common stock, which could result in lower trading volumes, liquidityyFE and prices of the common stock and make it more difficult for the combined companyyFE to raise capital. • If industryyFE or financial analyyFEsts do not publish research or reports about the combined companyyFYMMSN=Es business, or if theyyFE issue inaccurate or unfavorable research regarding the common stock, the share price and trading volume could decline. 30

Risk yFactors (continued) © yEnOcean 2022 | Sustainable IoT Risks Related to the Business Combination • The Proposed Business Combination mayyFE disrupt current plans and operations of the CompanyyFE. • If the Proposed Business Combination’s benefits do not meet the expectations of investors or securities analyyFEsts, the market price of SPAC’s securities or, following the consummation of the Proposed Business Combination, the combined companyyFYMMSN=Es securities, mayyFE decline. • The valuation ascribed to the combined companyyFE mayyFE not be indicative of the price that will prevail in the trading market following the Proposed Business Combination. If an active market for the combined companyyFYMMSN=Es securities develops and continues, the trading price of the combined companyyFYMMSN=Es securities following the Proposed Business Combination could be volatile and subject to wide fluctuations in response to various factors, which could contribute to the loss of all or part of yyFEour investment. • The combined companyyFE mayyFE be required to take write-downs or write-offs, or be subject to restructuring, impairment or other charges that could have a significant negative effect on the combined companyyFYMMSN=Es financial condition, results of operations and the price of our common stock, which could cause yyFEou to lose some or all of yyFEour investment. • Both (a) SPAC and (b) the CompanyyFE and Holdco will incur significant transaction costs in connection with the Proposed Business Combination. • SPAC, Holdco and the CompanyyFE mayyFE not successfullyyFE or timelyyFE consummate the Proposed Business Combination, including the risk that anyyFE required regulatoryyFE approvals are not obtained, are delayyFEed or are subject to unanticipated conditions that could adverselyyFE affect the combined companyyFE or the expected benefits of the Proposed Business Combination or that the approval of the stockholders of SPAC is not obtained. • The consummation of the Proposed Business Combination is subject to a number of conditions and if those conditions are not satisfied or waived, the Proposed Business Combination agreement mayyFE be terminated in accordance with its terms and the Proposed Business Combination mayyFE not be completed. • There is no guarantee that a stockholder’s decision whether to redeem its shares for a pro rata portion of the trust account will put the stockholder in a better future economic position. • Legal proceedings in connection with the Proposed Business Combination, the outcomes of which are uncertain, could delayyFE or prevent the completion of the Proposed Business Combination. • yFollowing the consummation of the Proposed Business Combination, the combined companyyFE will incur significant increased expenses and administrative burdens as a public companyyFE, which could have an adverse effect on its business, financial condition and results of operations. • Changes in laws or regulations, or a failure to complyyFE with anyyFE laws and regulations, mayyFE adverselyyFE affect the CompanyyFYMMSN=Es or the combined companyyFYMMSN=Es business, including the abilityyFE of the parties to consummate the Proposed Business Combination, and results of operations of the CompanyyFE or the combined companyyFE. • The abilityyFE to successfullyyFE effect the Proposed Business Combination and the combined companyyFYMMSN=Es abilityyFE to successfullyyFE operate the business thereafter will be largelyyFE dependent upon the efforts of certain keyyFE personnel of the CompanyyFE, all of whom we expect to stayyFE with the combined companyyFE following the Proposed Business Combination. The loss of such keyyFE personnel could negativelyyFE impact the operations and financial results of the combined business. • yEngaging in a cross-border business combination increases uncertaintyyFE on the abilityyFE to successfullyyFE close the deal as a cross-border transaction and it is significantlyyFE more complicated, time-consuming and expensive, and the parties mayyFE not be able to negotiate a transaction that is acceptable to SPAC’s stockholders or obtain all necessaryyFE approvals. 31

Risk yFactors (continued) © yEnOcean 2022 | Sustainable IoT Risks Related to the Business Combination (continued) • The laws governing non-U.S. entities mayyFE be different to the laws governing entities formed in the U.S. Material differences mayyFE include differences with respect to, among other things, distributions, dividends, repurchases and redemptions, the election of directors, the removal of directors, the fiduciaryyFE and statutoryyFE duties of directors, conflicts of interests of directors, the indemnification of directors and officers, limitations on director liabilityyFE, notice provisions for meetings, the exercise of voting rights, certain stockholder actions and uncertaintyyFE regarding tax policies of the jurisdiction of the combined companyyFE. • SPAC’s abilityyFE to complete an initial business combination mayyFE be adverselyyFE affected byyFE downturns in the financial markets or in economic conditions, increases in oil prices, inflation, increases in interest rates, supplyyFE chain disruptions, declines in consumer confidence and spending, the ongoing effects of the COVID-19 pandemic, including resurgences and the emergence of new variants, and geopolitical instabilityyFE, such as the militaryyFE conflict in the Ukraine. • A new 1% U.S. federal excise tax could be imposed in connection with redemptions. 32
