Neither the Company nor Quantum undertake any obligation to update, revise or review any forward-looking statement, whether as a result of new information, future developments or otherwise, except as may be required by any applicable securities laws. Notice to Investors The information set forth in this presentation has been prepared for informational purposes and there will not be any sales of the securities of the Company or Quantum in any jurisdiction until a definitive agreement in respect of the Business Combination has been entered into. In addition, the information contained in this presentation is as of the date hereof, and, except as required by applicable law, neither the Company nor Quantum has any obligation to update such information, including in the event that such information becomes inaccurate. This presentation may include material non-public information and, by receipt of this presentation, the recipient agrees to comply with all applicable laws and regulations with respect to the use of any such information. You acknowledge that you are aware that the applicable securities laws prohibit any person who is in possession of material non - public information from purchasing or selling securities or from communicating such information to any other person or entity under circumstances in which it is reasonably foreseeable that such other person or entity is likely to purchase or sell such securities while in possession of such information. This presentation shall neither be deemed an indication of the state of affairs of the business of the Company or Quantum nor constitute an indication that there has been no change in the business affairs of the Company or Quantum since the date hereof or since the dates as of which information is given in this presentation. In furnishing this presentation, neither the Company nor Quantum undertakes any obligation to provide the recipient with access to any additional evaluation materials or to update the information contained herein. Financial Information This presentation contains financial forecasts for the Company and the combined company with respect to certain financial results. Neither the Company’s nor Quantum’s respective independent auditors have audited, studied, reviewed, compiled or performed any procedures with respect to these projections for the purpose of their inclusion in this presentation, and none of the Company, Quantum or their respective auditors express any opinion or provide any other form of assurance with respect thereto for the purpose of this presentation. These projections are forward-looking statements and should not be relied upon as being necessarily indicative of future results. In this presentation, certain of this projected information has been provided for purposes of comparisons with historical data. Further, the assumptions and estimates underlying this prospective information are inherently uncertain and are subject to a wider variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in such prospective information. Accordingly, there can be no assurance that this prospective information is indicative of the future performance ofthe Company, Quantum or the combined company or that actual results will not differ materially from those presented in this prospective information. Disclaimers (Cont.) 2

Financial Information (Cont.) Inclusion of this prospective information in this presentation should not be regarded as any representation or warranty by any person that the results contained in such prospective information will be achieved. Further, the financial information and data contained herein in respect of the Company have been prepared on the basis of a fiscal year ending on March 31 of each year, for example fiscal year ended 2020 ended on March 31, 2020 and fiscal year ended 2021 ended on March 31, 2021, and as such may not be comparable with the financial information and data of other companies, including competitors, who do not use the same fiscal year end. Certain amounts, percentages and other figures included in this presentation have been subject to rounding adjustments. Certain other amounts that appear in this presentation may not sum due to rounding. Non-GAAP Information This presentation includes non-GAAP financial measures, including Adjusted EBITDA and Adjusted Pre-tax Income (Loss). Adjusted EBITDA represents net income (loss) attributable to the Company before net interest expense, income tax provision (benefit), depreciation and amortization, and excludes certain other expenses or items, including swap fair value gains (losses), severance expenses, write-offs, certain contractual settlements and cryptocurrency timing gains and losses. Adjusted Pre-tax Income (loss) represents net income (loss) attributable to the Company before income tax provision (benefit), and certain expenses and other items, including swap fair value gains (losses), severance expenses, write-offs, certain contractual settlements and cryptocurrency timing gains and losses. The Company believes these non-GAAP measures of financial results provide useful information to management and investors regarding the Company’s liquidity, financial condition and results of operations as wellas regarding period-over-period performance of the same. The Company does not consider these non-GAAP measures in isolation or as an alternative to liquidity or financial measures determined in accordance with GAAP. A limitation of these non-GAAP financial measures is that they exclude significant items that are required by GAAP to be recorded in the Company’s financial statements. In addition, they are subject to inherent limitations as they reflect the exercise of judgments by management about which items are excluded or included in determining these non-GAAP financial measures and therefore the basis of presentation for these measures may not be comparable to similarly-titled measures used by other companies. You should review the Company’s audited financial statements, and not rely on any single financial measure to evaluate the Company’s business. 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 projectedmeasures, together with some of the excluded information not being ascertainable or accessible, the Company is 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 and no reconciliation of the forward-looking non-GAAP financial measures is included. Industry and Market Data In this presentation, the Company and Quantum rely on and refer to certain information and statistics obtained from third-party sources which they believe to be reliable. However, neither the Company nor Quantum has independently verified the accuracy or completeness of any such third-party information. The recipient is cautioned not to give undue weight to such industry and market data. Trademarks, Trade Names and Service Marks This presentation includes trademarks, trade names and service marks that are the property of their respective owners, and are protected under applicable intellectual property laws. Solely for convenience, trademarks, trade names and service marks referred to in this presentation (such as “TradeStation,” a registered trademark of the Company) may appear without the ®, TM or SM symbols, but such references are not intended to indicate, in any way, that the Company or Quantum will not assert, to the fullest extent under applicable law, rights or the right of the applicable licensor to these trademarks, trade names and service marks. This presentation may also contain trademarks, trade names and service marks of other parties, and neither the Company nor Quantum intends the use or display of other parties’ trademarks, trade names or service marks to imply, and such use or display should not be construed to imply, a relationship with, or endorsement or sponsorship of, these other parties.

“Available Digital Marketing Impressions” is an estimate of the total number of Digital Marketing Impressions available to be purchased for a given period for TradeStation’s “Target Audience,” and is segmented by the types of campaigns TradeStation seeks to conduct (Search Engine, Social Media, and Display). “Target Audience” means the market audience a firm like TradeStation seeks to reach based on certain parameters and demograp hics, such as user behavior, user interests, geographical region, age and numerous other demographics and demonstrated behaviors, and this audience can be a pre-packaged, “in-house” custom audience organized and made available by providers such as Google and Facebook. The Company’s sources for estimating the size of its Target Audience in order to estimate Available Digital Marketing Impressions include Google, Twitter, Facebook, LinkedIn Ads Manage r and TheTradeDesk. “Digital Marketing Impression” describes the moment at which an advertisement or any other form of digital media renders on auser's screen. This does not measure any actions taken by the user, only the appearance of the ad or impression that the user may choose at which to look and on which to click or otherwise act or not act. “Digital Marketing Impressions Purchased” means, with respect to each type of campaign (Search Engines, Social Media, and Display), the number of Digital Marketing Impressions to occur throughout the Target Audience during a specified period. With respect to such purchases by ca mpaign segment, “Search Engine” means, for example, the Google Search Engine, “Social Media” means channels such as Twitter, Facebook, Instagram, LinkedIn, Reddit, etc., and “Display” refers to display ads such as banners, images, videos and text ads on relevant third-party sites. “Affiliate Marketing” means a lead referral program that consists of agreements with numerous third -party websites to generate online account-opening leads for TradeStation via TradeStation click-through ads on those websites. TradeStation pays a fee for each completed application or opened account. This program is facilitated through the use of a third-party vendor platform that organizes and manages these relationships, and aggregates and categorizes the third-party websites who wish to participate. Please note that the term “affiliate” as used here is not meant to imply in any way that th e third-party websites are affiliates of TradeStation as they are in fact independent businesses Endnote to Page 22 37

Note: (1) “Swap Fair Value Gain” ref ers to the change in f air value of an interest rate swap instrument with TradeStation’s parent company (Monex) that expired 11/27/2018. There have been no further interest rate swap agreements with Monex. (2) “Sev erance Expense” refers to a planned reduction-in-force (RIF) that was made in Q1 of FYE 3/31/21 as a proactive measure in response to the then-recent onset of “zero commissions” and declines in the federal funds target rates. (3) Includes write-off of Core FX software in FYE 3/31/19 and of Next Gen OX in FYE 3/31/20. (4) “Market Data Audit Settlement” refers to a settlement made in 3/31/19 (relating to prior periods of market data use and distribution) for an amount $1.2 million lower than had been accrued. (5) “Cry pto Timing Gains and Losses” refers to temporary gains and losses recognized due to certain mark -to-market adjustments, but later offset (netted to zero) as the asset positions were closed out. These temporary gains and losses (and related EBITDA adjustments) should not recur, as the Company has since adopted hedge accounting with respect to cryptocurrency assets and liabilities. (6) No Swap Fair Value Gain or Market Data Audit Settlement adjustments for CY 2019 or CY 2020. The severance expense adjustment was $0 for CY 2019 and $1.7 million for CY 2020.

39 How the Company is Projecting • Account growth increases are driven primarily by increased marketing spend • No significant new products, features or enhancements are required near- to mid-term for increased marketing spend to drive account growth • Net account additions generate increased trading-related revenues, including PFOF, and increased net interest income • Incremental gains in net interest income begin in FYE 3/31/24 generated by small increases that year in applicable interest rates, based on the 1- month USD LIBOR forward yield curve • Revenue per account declines as customer mix changes to higher percentage of millennials / Gen Z (who have lower cash balances to generate net interest income and trade less frequently), as well as anticipated price compression on fees and commissions generally • Wallet share increases from growing number of customers trading multiple asset classes (primarily equities, options and crypto) • Among asset classes, growth in equities accounts is largest driver, followed by crypto accounts, which is highest percentage account growth driver • Marketing spend increases significantly, reaching ~$147 million by FYE 3/31/24. Initial increase in outlay to be partially financed through the proceeds from this transaction. • Account acquisition cost increases near-term as the Company seeks to achieve greater brand awareness, then begins to gradually decline • Variable costs, such as cost of service provided, certain headcount-related costs and communications costs increase in line with account growth and associated revenues • Technology infrastructure costs increase to support higher trading volumes and other aspects of growth of the business Revenue Expenses TradeStation’s Assumptions Include:

(2) Zero-Commissions (TradeStation Salutes) refers to zero-commission equities account plans that have been offered to military veterans and first responders for several years prior to the COVID Period. (3) Zero-Commissions (Open to All) refers to zero-commission equities account plans that have been offered to all customers prior to the COVID Period, including TS Go and TS Select (launched 10/2019) and TradeStation Salutes. (4) Actual Post-COVID Period means April-August 2021. (5) Equity options trade volume was not impacted to the same extent as equities trade volume during the COVID period.

Risk Factors The following risk factors relate to TradeStation and its business, financial condition, results of operations and prospects, in particular in the context of TradeStation becoming a publicly -traded company as contemplated by the proposed business combination with Quantum, as described in this presentation. Accordingly, the words “we,” “our,” “us” and similar terms used in these risk factors refer to TradeStation in that context. Investing in our common stock involves a high degree of risk. You should carefully consider each of the following risk factors, as well as the other information in this presentation, before deciding whether to invest in our securities. If any of the following risks actually occurs, our business, financial condition, results of operations and prospects could be materially adversely affected. In that event, the market price of our common stock could decline significantly and you could lose all or part of your investment. The risks described below are not the only risks we face. Additional risks of which we are not presently aware, or that we currently believe are immaterial, could also materially adversely affect our business, financial condition, results of operations and prospects, and the market price of our common stock could decline and you could lose part or all of your investment. Risks Related to Our Business • The financial projections included in this presentation represent the estimates of our management as of August 31, 2021 with respect to our potential results of operations for the periods presented and are based on a number of inputs, estimates and assumptions, certain of which are described in this presentation. There can be no assurance thatany of such projections, or the inputs, estimates or assumptions on which they are based, can or will be achieved (in whole or in part) or that they are accurate in any respect. • Our results of operations and other operating metrics may fluctuate significantly from quarter to quarter, which could resultin frequent volatility in our share price. • Our business and reputation may be harmed by changes in business, economic or political conditions or events that impact fina ncial markets, including systemic market events or substantial or systemic regulatory events or changes. • Because a majority of our revenue is transaction-based (including brokerage commissions and fees and payment for order flow (“PFOF”)), continued commission-and-fee price compression (or elimination), or reduced levels of market trading activity, volume or volatility, or regulatory changes that limit or eliminate any of these types of revenue, may result in slower or no growth, higher account acquisition cost or reduced revenue and profitability. • Intense competition in our industry led to “zero commission” plans for retail trading transactions. Should such commission elimination in our industry increase in scope, or begin to be offered with respect to the other asset classes we offer for trading on our platforms, such pricing pressure and any response we undertake could materially andadversely harm our ability to generate revenue. • If we are unable to manage our growth successfully, our financial performance may suffer and our brand, reputation and compan y may be harmed. • If we fail to retain existing customers or attract new customers in a cost-effective manner (or in general), or if our customers decrease their use of our products and services, our account and revenue growth could be slower than we expect or negative and our business may be materially harmed. • Proposed legislation that would impose taxes on certain financial transactions could, if adopted, reduce our new account grow th and account retention, client activity, trade volume and revenue (and increase our expenses). • We may require additional capital to satisfy our liquidity needs and support our business growth and objectives, and this cap ital might be subject to delays and other limitations imposed by applicable regulations, might not be available to us on reasonable terms, if at all, and may result in shareholder dilution and limitations to our businessand operations. • A significant portion of our revenue depends on the interest income we can earn on our customers’ assets in our custody. We are therefore subject to interest rate risk and fluctuations in the market, which we do not control. • Our clearing operations expose us to liability for errors in clearing functions which could cause losses, regulatory enforcementfines and sanctions, and reputational harm. • The loss of key employees could decrease the quality of our management and operations. 42

Risk Factors (Cont.) • We conduct our brokerage and other business operations through subsidiaries and rely primarily on dividends from our subsidia ries for our cash flows. • Future acquisitions of, or investments in, other companies, products, technologies or specialized employees, should we decideto engage in such transactions, could require significant management attention, disrupt our business, dilute shareholder value and adversely affect our business and operations. • We are exposed to various risks associated with our non-U.S. business, including, among others, the failure to maintain all necessary approvals, consents, licenses or registrations required to operate such non-U.S. business, unexpected changes in regulatory requirements, expropriations, fluctuations in currency exchange rates, limitation on the import and export of currency, and political, social and economic instability. • Unfavorable media coverage, both traditional and social, could harm our business, financial condition and results of operations. • We operate in highly competitive markets, and many of our competitors have greater resources than we do and may have productsand services that may be more appealing than ours to our current and potential customers. • Our growth will depend, in part, on the success of our important relationships with third parties, including critical vendorsand third-party relationships related to marketing, lead referrals and account growth. Overreliance on certain third parties, or our inability to maintain or extend existing relationships or establish to new relationships on favorable terms or at all, may cause unanticipated costs or decreased account growth and revenue for us, negatively impact client awareness of, or engagement with, us and impact our financial performancein the future. • Self-directed investment and trading for retail customers is a fast-changing industry with many new challengers and technologies, and if we do not keep pace with industry and technological changes and innovation and continue to provide new and innovative products and services, including those that enable us to create or retain a differ entiated position in the market, our business may become less competitive and may be materially and adversely impacted. • Our introduction of new products and services, or changes to existing products and services, could fail to attract or retain customers or generate growth and revenue. • The continuing and long-term impact of the COVID-19 pandemic on our business, financial condition and results of operations is uncertain and may be materially adverse. Risks Related to Our Equities, Options and Futures Brokerage Products and Services • If we do not maintain our capital levels, or do not satisfy our cash deposit, collateral, custody, liquidity and settlement obligations, as required under applicable laws, rules and regulations and by applicable regulators, our equities, options and futures brokerage businesses may be restricted and we may be fined or subject to other disciplinaryorcorrective actions or even potentially being liquidated or wound down. • Our compliance and risk management policies and procedures as a regulated financial services company may not be fully effecti ve in identifying or mitigating noncompliance and risk exposure in the market environments or against all applicable types of risk, and we may be required to expend considerable time and cost to expand our compliance and risk infrastructure. • Our exposure to credit risk with customers and counterparties could result in uncollectable unsecured debits and counterpartyobligations and other potentially unrecoverable losses owed to us. • Providing investment education tools could subject us to additional risks and costs, including reputational and litigation risks, and if such tools are construed to be investment advice or recommendations, we would face significant cost and disruption to our business. • Our peer-to-peer and similar social communities and forums, which we intend to expand, may subject us to additional risks and compliance obligations and costs, in particular in areas such as investment advice, trade solicitation and market manipulation, which each would require substantial ongoing monitoring and review, at potentially significant costs, to try to prevent or mitigate inappropriate conduct in those areas. • Applicable regulators have publically expressed a focus on peer-to-peer and similar social communities and forums in our industry, and may disagree with the appropriateness of the activities in such communities and forums, make costly inquiries and investigations, issue adverse guidance or interpretations or take detrimental enforcement actions. 43

Risk Factors (Cont.) Risks Related to Our Cryptocurrency Products and Services • The market for cryptocurrency is fragmented, volatile and unpredictable, which may prevent customers from easily entering or liquidating their cryptocurrency positions and which may increase their losses or prevent them from realizing their gains, or result in large losses over a short period of time. • Cryptocurrency is believed by many to attract a disproportionately high (as compared to legal tender and other asset classes)number of bad actors who engage, or seek to engage, in cyber-attacks, fraud, theft, money laundering and other crimes or illegal or prohibited activities. Additionally, transactions in cryptocurrency may be irreversible and, accordingly, losses due to fraudulent or accidental transactions may not be recoverable. • Cryptocurrency is not legal tender, is not backed by the U.S. government (or most other governments), and customer balances are not covered by FDIC or SIPC protections. The value of a cryptocurrency may be derived in large part from the continued willingness of market participants to exchange legal tender for cryptocurrency, or aparticular cryptocurrency for another, which, if such willingness diminishes or disappears, may result in permanent and total loss of value for that particular cryptocurrency. • The underlying technology of a cryptocurrency may suddenly change, such that the new version of the cryptocurrency is no long er compatible with existing versions or there is otherwise a permanent divergence of the cryptocurrency’s blockchain (often called a “Fork”), which could materially adversely impact the value, functionality andother characteristics of the cryptocurrency. • The nascent, novel and evolving nature of cryptocurrency creates greater risks when compared to other asset classes, which inturn raises the risk of harm to our customers and us, the creation of unrecoverable losses to our customers and us, and negative regulatory and political actions. These risks may result in substantial claims and other actions being brought against us by customers, regulators and other authorities, which may result in large judgments, settlements, fines, cease-and-desist and similar orders or sanctions, which could limit ourcryptocurrency business or eliminate parts of it, and which harm our brand, reputation, business, financial condition and results of operations. • Regulation of the cryptocurrency industry is incipient, fragmented and complex and will likely change substantially. Our interpretations of any cryptocurrency regulation may be subject to challenge by the relevant regulators and our failure to comply with such regulation may negatively impact our ability to allow customers to buy, hold and sell cryptocurrencies with us in the future and may significantly and adversely affect our business, financial condition and results of operations. • Certain state and federal regulators have recently challenged or questioned, including directly with us, the legality or appropriateness of a cryptocurrency exchange or brokerage firm hypothecating or lending its customers cryptocurrency assets that are in its custody, and/or paying interest to customers on their cryptocurrency balances. Should these practices be prohibited or limited, we may have to withdraw from or cease our cryptocurrency lending activities in certain states or totally, and no longer be able generate the revenue associated wit h cryptocurrency lending. Being unable to pay interest on customer cryptocurrency account balances could diminish the growth of our cryptocurrency account base or result in certain customers decreasing the amount ofbusiness they do with us or ceasing to do business with us altogether. • Any inability on our part to maintain adequate relationships with licensors of our core cryptocurrency brokerage technology, cryptocurrency custody providers or cryptocurrency liquidity providers, or other relevant vendors or service providers, could negatively impact our operations. Risks Related to Regulation and Litigation • Because we self-clear all of our asset classes, we are required to be in compliance with numerous, complex and changing regulatory frameworks, rules and regulations imposed by numerous and distinct regulatory authorities and to maintain a significant regulatory financial and operations compliance infrastructure. Changes in these law s and regulations, failure to comply with these laws and regulations, and proceedings and investigations related thereto, could harm our business, financial condition and results of operations. • Public officials have signaled an increased focus on new or additional regulations that could impact our business and requireusto make significant changes to our business model and practices, including with respect to social communities, gamification, PFOF, cryptocurrency lending, and paying crypto interest on customer crypto account bala nces. Changes in these regulations, failure to comply with these regulations, or proceedings and investigations related thereto, could harm our business, financial condition and results of operations. 44

Risk Factors (Cont.) • PFOF represents a significant portion of our revenue and substantial reduction or elimination of PFOF could have a material adverse effect on our business, financial condition and results of operations. • We are exposed to substantial risks of liability under federal and state securities laws, other federal and state laws and courtdecisions, as well as rules and regulations promulgated by the SEC, the CFTC, state securities regulators, self-regulatory organizations and foreign regulatory agencies. • We are subject to legal proceedings and claims in the ordinary course of our business, which could cause us to incur significantlegal expenses. An adverse resolution of any future legal proceedings or claims could result in a negative perception of us and have a material adverse effect on our business, financial condition and results of operations. • We are subject to governmental laws and requirements regarding economic and trade sanctions, anti-money laundering and counter-terror financing that could impair our ability to compete in international markets or subject us to criminal or civil liability if we violate them. Failures to comply with these laws and requirements could result in substantial fines, costly undertakings and regulatory actions that could limit our business activities. These risks may be elevated for brokerage firms for self-directed investors who open accounts and execute account transactions in an online environment, particularly for brokerage firms that offer cryptocurrency investment, trading, deposits and withdrawals. • We are subject to anti-corruption, anti-bribery and similar laws, and non-compliance with such laws can subject us to criminal or civil liability, substantial fines, costly undertakings, reputational damage and regulatory actions that could lead to significant fines or limitations our business activities. • We cannot assure that all of our employees or agents will comply with our internal policies and applicable law, including anti-corruption, anti-bribery and similar laws. We may be ultimately held responsible for any such non-compliance. If and as we increase our international business, our compliance risks may increase. • The expected phase-out of LIBOR could negatively impact our net interest income and could have other material adverse effects. • Our future efforts to sell shares or raise additional capital may be subject to delays and other limitations imposed by applicable regulations. Risks Related to Our Platform, Systems and Technology • Our platform and systems have been, and may in the future be, subject to interruption, including extended outages, and instability due to operational and technological failures, whether internal or external, which could have a material adverse effect on our operations, brand, reputation and ability to acquire and retain customers. • Our products and internal systems rely on software that is highly technical, and these systems may contain errors, latencies, bugs or vulnerabilities, and we may be unsuccessful in addressing or mitigating any such technical limitations, defects or vulnerabilities in our systems in a timely fashion, or at all, which could have a material adverse effect on our operations, brand, reputation and ability to acquire and retain customers. • Our success depends in large part upon effective interoperability with mobile operating systems, networks, technologies, products, hardware and standards that we do not control. • We rely on third parties to perform certain key functions, including provision of market data, clearing and settlement, and supporting certain product offerings and cloud-based environments, and their failure to perform those functions could materially adversely affect our business, operations, brand, reputation and ability to acquire and retain customers. • Internet-related issues, which are largely outside of our control, including regulation, speed and quality of service, and the ability to conduct effective digital marketing, may negatively affect the quality of our services and our ability to grow and retain customer accounts. Risks Related to Cybersecurity and Data Privacy • Our business could be materially and adversely affected by a cybersecurity breach or other attack involving our computer and information technology systems or data, or those of our customers or third-party service providers, and could materially or permanently damage our business, financial condition and results of operations. 45

Risk Factors (Cont.) • Potential ransomware attacks are, and will likely continue to be, a large and serious threat to our business, and businesses like ours, and they are difficult to detect, prevent or defend against, and could materially or permanently damage our business, financial condition and results of operations. • We collect, store, share, disclose, transfer, use and otherwise process customer information and other data, including personal data, and an actual or perceived failure by us or our third-party service providers to protect such information and data or respect customers’ privacy could damage our reputation and brand, negatively affect our ability to retain customers and harm our business, financial condition and results of operations. • We are subject to stringent laws, rules, regulations, policies, industry standards and contractual obligations regarding data privacy and security and may be subject to additional related laws and regulations in jurisdictions into which we expand. Many of these laws and regulations are subject to change and reinterpretation and could result in claims, changes to our business practices, monetary penalties, increased cost of operations or other harm to our business, financial condition and results of operations. Risks Related to Our Intellectual Property • Any failure to obtain, maintain, protect, defend or enforce our important intellectual property rights, which consist primarily of our proprietary software technology which constitutes the core platform service offerings we provide, and our “TradeStation” and other trademarks, could adversely affect our business, financial condition and results of operations. • We have been, and may in the future be, subject to claims that we violate certain third-party intellectual property rights, principally software technology patents, which can be costly to defend and expensive to settle (even if they are meritless), and such claims, if successful, could materially adversely affect our ability to continue to provide or use important aspects of our product offerings and internal systems on reasonable terms, or at all. • We may not be able to obtain, maintain, protect, defend or enforce our trademarks and trade names, or build name recognition in our markets, thereby harming our competitive position. • We may be unable to continue to use the domain names that we use in our business or prevent third parties from acquiring and using domain names that infringe, misappropriate or otherwise violate, are similar to, or otherwise decrease the value of, our brand, trademarks, or service marks. • Some of our products and services, and information technology systems, contain or use open source software, which may pose particular risks, including potential security vulnerabilities, licensing compliance issues and quality issues. • We may be unable to halt the operations of third-party websites that aggregate or misappropriate our data or seek to impersonateus to steal business or defraud our customers or potential customers. • If we fail to comply with our obligations under license or technology service agreements with third parties that are critical to our business or were to lose those technology license/service agreements due to actions or other facts pertaining to the licensors/service providers, and are unable to timely replace them on reasonable terms, we may be required to pay damages or lose rights and technology that are critical to our business. Risks Related to Owning Our Stock • A market for our common shares may not develop or be sustained, which would adversely affect the liquidity and price of our common shares. If securities or industry analysts do not publish research, or publish unfavorable research (even if inaccurate), about our business, the price and liquidity of our common shares could decline. • Sales of a substantial number of our common shares in the public market by our existing shareholders could cause our share priceto decline. • After the closing of the business combination, a significant number of our common shares are subject to issuance upon exercise of outstanding warrants and vesting and earn-out formulas, which may result in dilution to our shareholders. • Our future ability to pay cash dividends to shareholders is subject to the discretion of our board of directors and will be limited by our ability to generate sufficient earnings and cash flows. We do not anticipate paying any dividends for the foreseeable future. 46

Risk Factors (Cont.) • NYSE or Nasdaq, as applicable, may delist our securities from trading on its exchange, which could limit investors’ ability to make transactions in our securities and subject us to additional trading restrictions. • Having a minority ownership interest in our company will mean that you may not have meaningful influence on our management. Risks Related to Our Relationship with Monex • Following the business combination, Monex will continue to control the direction of our business. Monex’s concentrated ownershipof our outstanding common shares may prevent you and other shareholders from influencing significant decisions. • We will be a “controlled company” within the meaning of the rules of the NYSE and Nasdaq and, as a result, will qualify for, and may rely on, exemptions from certain corporate governance requirements. If we rely on such exemptions, you will not have the same protections afforded to shareholders of companies that are subject to such requir ements. • If Monex sells a controlling interest in us to a third party in a private transaction, you may not realize any change-of-controlpremium on your common shares and we may become subject to the control of a presently unknown third party, whose interest may be adverse to yours. • If Monex experiences a change in control, our current plans and strategies could be subject to change. • We have commercial relationships with Monex. Conflicts of interest and other disputes may arise between Monex and us that maybe resolved in a manner unfavorable to us or our other shareholders. • After the business combination, certain of our officers and directors may have actual or potential conflicts of interest becauseof their equity interest in or relationships with Monex. Also, certain of Monex’s current directors and officers currently are, and are expected to continue as, our directors, which may create conflicts of interest or the appearance of conflicts of interest. Risks Related to Being a Public Company • The audit opinion with respect to the audit, conducted in accordance with the Public Company Oversight Board (“PCAOB”) standa rds, of the financial information included in this presentation has not been delivered yet. Therefore, we cannot assure you that there will not be potentially material differences between the presentation of our financial information included in this presentation and that presented in the proxy statement/prospectus prepared in connection with the proposed business combination. • The majority of our management team has no experience managing a public company. • We will incur increased costs as a result of operating as a public company, and our management will devote substantial time t o new compliance initiatives. • If we fail to maintain an effective system of disclosure controls and internal controls over financial reporting, our abilityto produce timely and accurate financial statements or comply with applicable regulators could be impaired. • If our estimates or judgments relating to our critical accounting standards prove to be incorrect, or such standards change over time, our results of operations could be adversely affected. • We may be unable to maintain the listing of our securities in the future. Risks Related to the Business Combination • Quantum may not have sufficient funds to consummate the business combination. • We have not yet entered into a definitive agreement for a business combination with Quantum and, even if we are able to come to an agreement, the completion of the business combination will be subject to the satisfaction of certain closing conditions, including the approval of the business combination by Quantum’s shareholders. 47

Risk Factors (Cont.) • We and Quantum will incur significant transaction costs in connection with the business combination. • Subsequent to the completion of the business combination, 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 common share price, which could cause you to lose some or all of your investment. • The business combination may be completed even though material adverse effects may result from the announcement of the busine ss combination, industry-wide changes and other causes, and even if Quantum raises substantially less than or otherwise fails to deliver the net proceeds targeted to be raised in connection with the business combination. • Delays in completing the business combination may substantially reduce the expected benefits of the business combination. • We or Quantum, or both, may be a target of securities class action and derivative lawsuits, which could result in substantialcosts and may delay or prevent the business combination from being completed. 48
