Risk Factors 42 All references to the “Company,” “Events.com,” “we”, “us” and “our” refer to Events.com, Inc. prior to the consummation of the Proposed Transaction, and the combined company following the consummation of the Proposed Transaction. The risks presented below are certain of the general risks related to the Company’s business, industry and ownership structure and are not exhaustive. The list below is qualified in its entirety by disclosures contained in future filings by the Company, or by third parties (including Concord Acquisition Corp II) with respect to the Company, with the SEC. These risks speak only as of the date of this Presentation and neither the Company nor Concord makes any commitment to update such disclosures. The risks highlighted in future filings with the SEC may differ significantly from and will be more extensive than those presented below. • We are an early-stage company with a history of losses, and expect to incur significant losses for the foreseeable future. • We may not be able to achieve our expected business milestones or launch products on our anticipated timelines. • The COVID-19 pandemic has had a material negative impact on our business and operating results and any re-occurrence or similar pandemics could materially affect our business. • Our business is dependent on the continued occurrence of sporting events, concerts and theater shows and on relationships with buyers, sellers and distribution partners and any change in such occurrence or relationships could adversely affect our business. • Changes in Internet search engine algorithms or changes in marketplace rules could have a negative impact on traffic for our sites and ultimately, our business and results of operations. • We face intense competition in the event space. • If we do not continue to maintain and improve our platform and brand or develop successful new solutions and enhancements or improve existing ones, our business will suffer. • We may be adversely affected by the occurrence of extraordinary events or factors affecting concert, sporting and theater events. • We may be unsuccessful in potential future acquisition endeavors and we may not be successful in integrating past acquisitions into our business. • The failure to retain, motivate or integrate any of our senior management team or other skilled personnel could have an adverse effect on our business, financial condition or results of operations. • The processing, storage, use and disclosure of personal data could give rise to liabilities as a result of governmental regulation, conflicting legal requirements or applications of privacy regulations. • Unfavorable legislative outcomes, or outcomes in legal proceedings in which we may be involved, may adversely affect our business and operating results. • System interruption and the lack of integration and redundancy in our systems and infrastructure may have an adverse impact on our business, financial condition and results of operations. • Cyber security risks, data loss or other breaches of our network security could materially harm our business and results of operations. • We may fail to adequately protect or enforce our intellectual property rights or face potential liability and expense for legal claims alleging that the operation of our business infringes intellectual property rights of third parties. • Our payments system depends on third-party providers. • The announcement of the Proposed Transaction could disrupt Events.com’s business. • The dual class structure of our Common Stock has the effect of concentrating voting control with our co-founders. This will limit or preclude your ability to influence corporate matters, including the outcome of important transactions, including a change in control. • Directors and officers of Concord have potential conflicts of interest in recommending that stockholders vote in favor of approval of the Proposed Transaction. • Concord stockholders will have a reduced ownership and voting interest after the Proposed Transaction and will exercise less influence over management. • The ability of Concord stockholders to exercise redemption rights with respect to a large number of shares could deplete Concord’s trust account prior to the Proposed Transaction and thereby diminish the amount of working capital of the combined company after the Proposed Transaction (the “Combined Company”). • Concord’s initial stockholders, directors, officers, advisors, and their affiliates may purchase shares or public warrants from public stockholders, which may reduce the public “float” of Concord’s Class A common stock. • The Proposed Transaction may not be completed by Concord’s business combination deadline in its organizational documents, as amended to date, and Concord may fail to obtain an extension of the business combination deadline. • There can be no assurance that the Proposed Transaction will achieve the Company’s objectives of providing the Company with sufficient capital, and if the Company requires additional capital to fund its operations or expected growth, there can be no assurance that the Company will be able to obtain such funds on attractive terms or at all, and the Combined Company’s stockholders may experience dilution as a result. • The Company and Concord have incurred and will incur substantial costs in connection with the Proposed Transaction and related transactions, such as legal, accounting, consulting, and financial advisory fees. • While the Company and Concord work to complete the Proposed Transaction, management’s focus and resources may be diverted from operational matters and other strategic opportunities. • If PIPE financing is not identified by the Company and Concord, or if identified, is consummated on different terms than those currently contemplated or fails to close and sufficient stockholders exercise their redemption rights in connection with the Proposed Transaction, Concord may lack sufficient funds to consummate the Proposed Transaction. • The Company’s operations may be restricted during the pendency of the Proposed Transaction pursuant to terms of the merger agreement for the Proposed Transaction. • The announcement of the Proposed Transaction could disrupt the Company’s relationships with its customers, suppliers and others, as well as its operating results and business generally. • Uncertainty about the effect of the Proposed Transaction may affect the Company’s ability to retain key employees and integrate management structures and may negatively impact its management, strategy and results of operations.

Risk Factors 43 • The consummation of the Proposed Transaction is subject to a number of conditions and if those conditions are not satisfied or waived, the merger agreement for the Proposed Transaction may be terminated in accordance with its terms and the Proposed Transaction may not be completed. • The Combined Company may incur successor liabilities due to conduct arising prior to the completion of the Proposed Transaction. • Subsequent to the completion of the Proposed Transaction, the Combined Company may be exposed to unknown or contingent liabilities and 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 price of its securities. • The obligations associated with being a public company will involve significant expenses and will require significant resources and management attention, which may divert from the Combined Company’s business operations. • The Company’s management and current resources may not successfully or effectively manage the transition to a public company. • Future sales of common stock after the consummation of the Proposed Transaction may cause the market price of the Combined Company’s common stock to drop significantly, even if the Company’s business is doing well. • Following the Proposed Transaction, outstanding warrants will become exercisable for the Combined Company’s common stock, which would increase the number of shares eligible for future resale in the public market and result in dilution to the Combined Company’s stockholders. • The Combined Company does not intend to pay cash dividends for the foreseeable future. • The Combined Company may not meet the NYSE American’s initial listing criteria, and even if it does, the NYSE American may not continue to list the Combined Company’s securities on its exchange, which could limit the ability of investors in the Combined Company to make transactions in the Combined Company’s securities and subject the Combined Company to additional trading restrictions. • If the Proposed Transaction’s benefits do not meet the expectations of investors or securities analysts, the market price of Concord’s securities or, following the consummation of the Proposed Transaction, the Combined Company’s securities, may decline. • If securities or industry analysts do not publish research, or publish inaccurate or unfavorable research, about the Combined Company’s business, the price and trading volume of its securities could decline. • There has been no prior public market for the Company’s securities. The stock price of the Combined Company’s common stock may be volatile or may decline regardless of its operating performance. • Legal proceedings may be instituted against the Proposed Transaction, which could delay or prevent or otherwise adversely impact the Proposed Transaction.
