#1plastiq Investor Presentation T#2About this Presentation Disclaimer This investor presentation (this "Presentation") relates to a proposed business combination (the "Business Combination") between Colonnade Acquisition Corp. II ("Colonnade") and Plastiq Inc. (the "Company"). This Presentation does not contain all the information that should be considered with respect to the proposed Business Combination. It is not intended to form any basis of any investment decision or any decision in respect to the proposed Business Combination. This Presentation does not constitute (i) a solicitation of a proxy, consent or authorization with respect to any securities or in respect of the proposed Business Combination or (ii) an offer to sell, a solicitation of an offer to buy, or a recommendation to purchase any security of Colonnade, the Company, or any of their respective affiliates. Forward Looking Statements Certain statements, estimates, targets and projections in this Presentation may be considered forward-looking statements. Forward-looking statements generally relate to future events or Colonnade's or the Company's future financial or operating performance. For example, statements regarding anticipated growth in the industry in which the Company operates and anticipated growth in demand for the Company's services, projections of the Company's future financial results and other metrics, the satisfaction of closing conditions to the Business Combination and the timing of the completion of the Business Combination are forward-looking statements. In some cases, you can identify forward-looking statements by terminology such as "pro forma", "may", "should", "could", "might", "plan", "possible", "project", "strive", "budget", "forecast", "expect", "intend", "will", "estimate", "anticipate", "believe", "predict", "potential" or "continue", or the negatives of these terms or variations of them or similar terminology. Such forward-looking statements are subject to risks, uncertainties, and other factors which could cause actual results to differ materially from those expressed or implied by such forward-looking statements. These forward-looking statements are based upon estimates and assumptions that, while considered reasonable by Colonnade and its management, and the Company and its management, as the case may be, are inherently uncertain. Factors that may cause actual results to differ materially from current expectations 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 Merger Agreement with respect to the Business Combination; (ii) the outcome of any legal proceedings that may be instituted against Colonnade, the Company, the combined company or others following the announcement of the Business Combination and any definitive agreements with respect thereto; (iii) the inability to complete the Business Combination due to the failure to obtain approval of the stockholders of Colonnade; (iv) the inability of the Company to satisfy other conditions to closing; (v) changes to the proposed structure of the Business Combination that may be required or appropriate as a result of applicable laws or regulations or as a condition to obtaining regulatory approval of the Business Combination; (vi) the ability to meet stock exchange listing standards following the consummation of the Business Combination; (vii) the risk that the pendency of the Business Combination or time required to consummate the Business Combination disrupts current plans and operations of the Company; (viii) changes in applicable laws or regulations; (ix) the possibility that the Company or the combined company may be adversely affected by other economic, business, regulatory, and/or competitive factors; (xi) the Company's estimates of expenses and profitability; (xii) the evolution of the markets in which the Company competes; (xii) the ability of the Company to implement its strategic initiatives and continue to innovate its existing products; (xiii) the ability of the Company to defend its intellectual property; (xiv) the ability of the Company to satisfy regulatory requirements; (xv) the impact of the COVID-19 pandemic on the Company's and the combined company's business; and (xvi) other risks and uncertainties set forth in the portion of the annex to this Presentation entitled Risks Related to Our Business, Operations and Industry, the section entitled "Risk Factors" and "Cautionary Note Regarding Forward-Looking Statements" in Colonnade's Annual Report on Form 10-K, and other risks and uncertainties indicated from time to time in other documents filed to be filed with the SEC by Colonnade. If any of these risks materialize or if the Company's assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. There may be additional risks that are not presently known to the Company or Colonnade or that the Company or Colonnade currently believes are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect the Company's and Colonnade's expectations, plans or forecasts of future events and views as of the date of this Presentation. Forward-looking statements speak only as of the date they are made, and the Company and Colonnade undertake no obligation, and expressly disclaim any obligation, to update, alter or otherwise revise any forward-looking statements, whether as the result of new information, future events or otherwise, except as required by law. Nothing in this Presentation should be regarded as a representation by any person that the forward-looking statements set forth herein will be achieved or that any of the contemplated results of such forward-looking statements will be achieved. You should not place undue reliance on forward-looking statements, which speak only as of the date they are made. Neither Colonnade nor the Company undertakes any duty to update these forward-looking statements, except as required by law. Use of Projections This Presentation contains financial forecasts for the Company with respect to certain financial results for the Company's fiscal years 2022 through 2023. Neither Colonnade's nor the Company's independent auditors have audited, studied, reviewed, compiled or performed any procedures with respect to the projections for the purpose of their inclusion in this Presentation, and accordingly, they did not express an opinion or provide any other form of assurance with respect thereto for the purpose of this Presentation. These projections are forward-looking statements included for illustrative purposes only and should not be relied upon as being necessarily indicative of future results. In this Presentation, certain of the above-mentioned projected information has been provided for purposes of providing comparisons with historical data. The assumptions and estimates underlying the prospective financial 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 financial information. Accordingly, there can be no assurance that the prospective results are indicative of the future performance of the Company or that actual results will not differ materially from those presented in the prospective financial information. Inclusion of the prospective financial information in this Presentation should not be regarded as a representation by any person that the results contained in the prospective financial information will be achieved. 2#3Disclaimer Financial Information; Non-GAAP Financial Measures The financial information and data contained in this Presentation has not been audited in accordance with the standards of the Public Company Accounting Oversight Board and does not conform to Regulation S-X. Such information and data may not be included in, may be adjusted in or may be presented differently in the registration statement to be filed by Colonnade relating to the proposed Business Combination and the proxy statement/prospectus contained therein. This Presentation also includes certain financial measures not presented in accordance with U.S. generally accepted accounting principles ("GAAP") including adjusted EBITDA and certain ratios and other metrics derived therefrom. The Company defines adjusted EBITDA as earnings before interest, tax, depreciation, and amortization less stock-based compensation, internal-use software amortization and non- recurring expenses. These non-GAAP financial measures are not measures of financial performance in accordance with GAAP and may exclude items that 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 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. Colonnade 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. Colonnade and the Company believe 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 comparing the Company's financial measures with other similar companies, many of which present similar non- GAAP financial measures to investors. These non-GAAP financial measures are subject to inherent limitations as they reflect the exercise of judgments by management about which expense and income are excluded or included in determining these non-GAAP financial measures. Additionally, there can be no assurance that the Company will not modify the presentation of these or similar non-GAAP measures in the future, including to make adjustments for future expenses or other items that the Company believes are appropriate in comparing its operating performance across reporting periods on a consistent basis. This Presentation also includes 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, Colonnade 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. For the same reasons, the Company is unable to address the probable significance of the unavailable information, which could be material to future results. Industry and Market Data In this Presentation, the Company relies on and refers to certain information and statistics obtained from third-party sources which it believes to be reliable. Neither Colonnade nor the Company has independently verified the accuracy or completeness of any such third-party information. This data is subject to change. In addition, this Presentation does not purport to be all-inclusive or to contain all of the information that may be required to make a full analysis of the Company or the Business Combination. The recipient should make its own evaluation of the Company and of the relevance and adequacy of the information and should make such other investigations as it deems necessary. Trademarks and Copyright This Presentation may contain trademarks, service marks, trade names and copyrights of other companies, which are the property of their respective owners. Solely for convenience, some of the trademarks, service marks, trade names and copyrights referred to in this Presentation may be listed without the TM, SM, or ® symbols, but Colonnade and the Company will assert, to the fullest extent under applicable law, the rights of the applicable owners, if any, to these trademarks, service marks, trade names and copyrights.

These inputs include the expected common stock price volatility over the term of the awards, the expected term of the awards, risk-free interest rates, and expected dividend yield. Stock-based compensation expense for stock-based awards is recognized on a straight-line basis over the period during which an award holder is required to provide services in exchange for the award (generally the vesting period of the award). The company accounts for forfeitures as they occur. 2. Internal-use software reflects capitalized costs to develop internal-use software when preliminary efforts are successfully completed, management ahs authorized and committed project funding, it is probable that the project will be completed, and the software will be used as intended.

We have a history of operating losses and may not achieve or sustain profitability in the future. Future net revenue growth depends on our ability to retain existing customers, drive increased volume on our platform, and attract new customers in a cost-effective manner. Further, if our new products do not achieve sufficient market acceptance such products may not produce additional revenue. Our recent growth, ongoing changes in our industry, and our transaction mix make it difficult to forecast our net revenue and evaluate our business and future prospects. Our projections are subject to significant risks, assumptions, estimates and uncertainties, including assumptions regarding future legislation and changes in regulations. As a result, our projected revenues, market share, expenses and profitability may differ materially from our expectations. Our business relies on our arrangements with financial institutions, third party service providers, processing providers, disbursement providers and other financial services suppliers. If any of our arrangements with such financial institutions, third party service providers, processing providers, disbursement providers or financial services providers are terminated or significantly altered, it could adversely affect our business. Further, we do not have redundancies in place for many of these arrangements, and any outages or service interruptions from these providers and suppliers could result in service interruptions to our customers and adversely affect our business, results of operations, and financial condition. Our business relies on our relationships with payment card networks and issuing banks, including the categories allowed to be paid using our platform. If we are unable to maintain these relationships, our business may be adversely affected. Further, changes to the rules, practices or fees, including interchange fees, set by payment card networks or other banks, could harm our business. In addition, if we fail to comply with the applicable rules and policies of the payment card networks, they could seek to fine us, suspend us or terminate our ability to participate in such networks, which could adversely affect our business, results of operations, and financial condition. We facilitate the transfer of customer funds daily and are subject to the risk of both manual and technological/system errors, which could result in financial losses, damage to our reputation, and/or loss of trust in our brand, any of which would harm our business, results of operations and financial condition. Our risk management efforts may not be sufficient to deal effectively with fraud, bad transactions or other fraudulent activities, by payers, recipients, employees or other third parties, which could increase our loss rate, expose us to material financial losses and liability and otherwise harm our business. Following the Business Combination, we may still require additional capital to support the growth of our business, and this capital might not be available on acceptable terms, if at all. We expect indebtedness to remain outstanding following the Business Combination, which subjects us to additional financial and operating restrictions. 31#32Risks Related to Our Business, Operations and Industry Our estimates of market opportunity and forecasts of market growth may 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. 12. Unfavorable conditions in our industry or the global economy have adversely affected and could continue to adversely affect our business, results of operations, and financial condition. 13. Our business relies on the volume of the transactions paid through our platform. Currently a limited number of payers and limited number of recipients are responsible for a significant portion of our volume, and the loss or decline in volume from one or more of these customers could adversely affect our business, results of operations, and financial condition. IQ 11. 14. 15. 16. 17. 18. 19. 20. 21. 22. 23. 24. We may not be able to scale our business quickly enough to meet our customers' growing needs, and if we are not able to grow efficiently, our operating results could be harmed. Our business is seasonal, and we experience fluctuations in our quarterly results of operations that may not fully reflect the underlying performance of our business. We participate in markets that are competitive and continuously evolving, and if we do not compete effectively with established companies and new market entrants, our business, results of operations, and financial condition could be adversely affected. If we fail to integrate with our customers' and partners' APIs for their billing and payment systems and with third-party technologies, our platform may become less marketable and less competitive or obsolete and our operating results may be harmed. If we fail to manage our growth effectively, we may be unable to execute on our plans and strategies, maintain and grow customer adoption and use of our products and services, or adequately address competitive challenges. Such growth and expansion may also subject us to additional costs and risks, and our plans may not be successful. Failure to effectively develop, expand and scale our sales and marketing capabilities could harm our ability to increase our customer base and achieve broader market acceptance of our products. If we fail to offer high-quality customer support, or if our support is more expensive than anticipated, our business and reputation could suffer. If we fail to adapt and respond effectively to rapidly changing technology, evolving industry standards, changing regulations and payment methods, demand for product enhancements, new product features, and changing business needs, requirements or preferences, our platform may become less competitive. If the prices we charge for our services are unacceptable to our customers, our operating results may be harmed. We may expand our operations to new markets outside the United States and Canada, creating a variety of operational, legal and regulatory challenges. If we fail to maintain and enhance our brand, our ability to expand our customer base will be impaired and our business, operating results and financial condition may suffer. 32#33Risks Related to Our Business, Operations and Industry If we experience cyberattacks, or if our security measures are breached or unauthorized access to customer data is otherwise obtained, it could result in serious harm to our reputation, business and financial condition. 25. 26. If we fail to manage our technical operations infrastructure, our existing customers may experience service outages, which could harm our reputation and business. 27. 28. 29. 30. 31. 32. IQ 33. 34. We facilitate the transfer of customer funds daily, and are subject to the risk of errors, which could result in financial losses, damage to our reputation, or loss of trust in our brand, which would harm our business and financial results. Legal and Regulatory Risks Our business is subject to extensive government regulation and oversight, including by U.S. federal and state and Canadian federal and provincial authorities. Our failure to comply with extensive, complex, overlapping, and frequently changing rules, regulations, and legal interpretations could materially harm our business. These include, but are not limited to: payments regulations; Anti-Money Laundering and Counter-Terrorist Financing; Economic and Trade Sanctions; Foreign Corrupt Practices, Anti-Bribery and Anti-Corruption; Privacy and Protection of Customer Data, and the Payment Card Industry Data Security Standard. We rely on various exemptions from licensing, and regulators may find that we have violated applicable laws or regulations. If we fail to adequately protect our proprietary rights, our competitive position could be impaired, the value of our products, services and brand may be reduced, and we may lose valuable assets, generate less revenue and incur costly litigation to protect our rights. We may be sued by third parties for various claims including alleged infringement of their proprietary rights. Any future litigation against us could be costly and time-consuming to defend. Interruptions or delays in the services provided by third-party data centers, internet service providers and other technology providers could impair the delivery of our platform and our business could suffer. We use open source software in our products, and any failure to comply with the terms of one or more of these open source licenses could negatively affect our business or subject it to litigation. 33#34Risks Related to Being a Public Company and Financial Risks 35. IQ 36. 37. 39. 40. 41. 42. 43. 38. If securities or industry analysts do not publish research reports about our business, if they adversely change their recommendations regarding our shares or if our results of operations do not meet their expectations, our stock price and trading volume could decline. Our ability to use net operating loss carryforwards and other tax attributes may be limited in connection with the Business Combination or other ownership changes. Changes in our effective tax rate or tax liability may adversely affect our results of operations and financial condition. We could be required to collect sales, value added or similar taxes or be subject to other tax liabilities that may increase the costs our customers would have to pay for our solutions and adversely affect our business, results of operations and financial condition. Changes in financial accounting standards or policies have affected, and in the future may affect our reported financial condition or results of operations. If our estimates or judgments relating to our critical accounting policies prove to be incorrect, or if there are changes in accounting principles, our operating results could be adversely affected. 44. 45. We have previously identified material weaknesses in our internal control over financial reporting and may identify additional material weaknesses in the future or otherwise fail to maintain effective internal control over financial reporting, which may result in material misstatements of our consolidated financial statements or cause us to fail to meet our periodic reporting obligations or cause our access to the capital markets to be impaired. We depend heavily on third parties such as payment processors and financial institutions to provide us with complete and accurate data in order for us to report our revenue and cash balances, and as a result any incomplete or inaccurate data from such parties affects our ability to accurately report our financial condition and/or results of operations. Operating as a public company will require us to incur substantial costs and will require substantial management attention. In addition, our management team has limited experience managing a public company and the requirements of being a public company may strain our resources, divert management's attention and affect our ability to attract and retain additional executive management and qualified board members If a substantial number of Colonnade's public shares are redeemed in connection with the Business Combination, there may be a more limited market for our securities. The market price and trading volume of our securities may be volatile and could decline significantly following closing of the Business Combination. 34#35IQ General Risks The ongoing global COVID-19 pandemic has in the past adversely affected our business, results of operations, and financial condition, and the extent of any continued or new impacts will depend on future developments, which are highly uncertain and cannot be predicted. 46. 47. 48. 49. Our business, results of operations, and financial condition may continue to be impacted by macroeconomic events, such as inflation, recessions or depressions, and such impact could be materially adverse. Acquisitions, strategic investments, partnerships, collaborations or alliances could be difficult to identify and integrate, divert the attention of management, disrupt our business, dilute the combined company's stockholder value, and adversely affect our operating results and financial condition. We depend on our senior management team and the loss of our chief executive officer or one or more key employees or an inability to attract and retain highly skilled employees generally could adversely affect our business. 50. If we cannot maintain our company culture as we grow, we could lose the innovation, teamwork, passion and focus on execution that we believe contributes to our success and our business may be harmed. 35#36IQ Risks Related to the Business Combination Transaction Subsequent to the completion of the transaction, the combined company may be required to take write-downs or write-offs, restructuring and impairment or other charges that could have a significant negative effect on its financial condition, results of operations and the combined company's share price, which could cause you to lose some or all of your investment. 51. 52. 53. 54. 55. 56. 57. 58. 59. 60. 61. The transaction may be completed even though material adverse effects may result from the announcement of the business combination, industry-wide changes and other causes. Delays in completing the business combination may substantially reduce the expected benefits of the transaction. The ability of Colonnade's shareholders to exercise redemption rights with respect to a large number of outstanding shares of common stock could increase the probability that the transaction would not occur or reduce the combined company's cash and liquidity. Current Colonnade shareholders will own a smaller proportion of the post-closing company than they currently own of Colonnade. In addition, following the closing of the transaction, Colonnade may issue additional shares or other equity securities without the approval of its shareholders, which would further dilute the ownership interests and may depress the market price of its shares. Certain factors may have a material adverse effect on our business, financial condition and results of operations. The risks and uncertainties described above are not the only ones we face. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, may also become important factors that adversely affect our business. If any of these risks actually occurs, our business, financial condition, results of operations and future prospects could be materially and adversely affected. In that event, the trading price of our common stock following the transaction could decline, and you could lose part or all of your investment. The process of taking a company public by means of a business combination with a special purpose acquisition company is different from taking a company public through an underwritten offering and may create risks for our unaffiliated investors. Uncertainties about the business combination during the pre-closing period may cause a loss of key management personnel and other key employees. A market for the combined company's shares may not develop or be sustained, which would adversely affect the liquidity and price of the combined company's shares. Colonnade and Plastiq will incur significant transaction and transition costs in connection with the proposed business combination and the combined company will incur increased costs as a result of operating as a public company and its management will devote substantial time to new compliance initiatives. The sponsor of Colonnade has agreed to vote in favor of the business combination, which will increase the likelihood that Colonnade will receive the requisite stockholder approval for the business combination and the transactions contemplated thereby regardless of how Colonnade's public shareholders vote. 36#37IQ Key Assumptions Relating to Projected Financial Information of Plastiq The projected financial information is based on Plastiq's estimates and assumptions tied to its past performance for existing products and its expected performance for new products. Card volume and revenue assumptions can move significantly based on the macro economy. The projected financial information assumes an expansion of Plastiq's penetration into small and medium businesses across the United States. 1. 2. 3. 4. 5. 6. 7. 8. 9. Card volume is based on Plastiq's ability to continue to be productive with its marketing spend, drive sales efficiency and continue to execute on its ability to land new customers and retain the customers it has. The launch of Plastiq's recurring SaaS solution and Short-Term financing, both in March 2022, are not expected to be material to 2022 or 2023 volume, net revenue or gross profit. Both products are expected to be less than 10% of Plastiq's total 2023 net revenue. Transaction expenses associated with third party interchange and processors are projected to be flat to favorable in 2023. Plastiq expects a diversification of its existing revenue drivers in 2023 which in turn will have a favorable impact to its gross margin. Headcount is the number one expense for Plastiq, and its ability to attract and hire new talent is critical for all of its functions, especially in Sales and Marketing as Plastiq invests to grow these functions. The projected financial information assumes an expansion of Plastiq's employee base to a location with lower costs allowing us to achieve profitability in Plastiq's long-term model. Plastiq's business is capital intensive and its ability to raise funds to support its operations is critical to Plastiq's ability to meet the investments required in its financial model. The projected financial information assumes that Plastiq will receive at least $100M in net cash proceeds as a result of the transaction with Colonnade, after accounting for redemptions of Colonnade public shares. The successful expansion of Plastiq' business may require future M&A, although the projected financial information in this presentation does not include the impact of any acquisitions. The projected financial information also reflects numerous estimates and assumptions with respect to industry performance, general business, economic, regulatory, market and financial conditions and other future events, as well as matters specific to Plastiq's business, all of which are difficult to predict and many of which are beyond outside of Plastiq's control. Plastiq's financial projections constitute forward-looking information and are subject to risks and uncertainties including those set forth in the risk factors included in the appendix. 37#38plastic Powering the SMB economy
