Investor Presentation June 2021

Disclaimer About this Presentation This investor presentation (this “Presentation”) relates to a proposed business combination (the “Business Combination”) between Supernova Partners Acquisition Company, Inc. (“Supernova”) and OfferPad, Inc. (the “Company”). The information contained herein does not purport to be all-inclusive and none of Supernova, the Company or their respective affiliates or representatives makes any representation or warranty, express or implied, as to the accuracy, completeness or reliability of the information contained in this Presentation. 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 Supernova, the Company, or any of their respective affiliates. No offering of securities shall be made except by means of a prospectus meeting the requirements of Section 10 of the Securities Act of 1933, as amended, or an exemption therefrom. Forward Looking Statements Certain statements in this Presentation may be considered forward-looking statements. Forward-looking statements generally relate to future events or Supernova’s or the Company’s future financial or operating performance. For example, statements regarding, and projections of, the Company’s future financial results and other metrics and ownership of the combined company following the Business Combination, anticipated growth in demand for the Company’s services, anticipated growth in the industry in which the Company operates and the anticipated timing of the proposed 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 Supernova 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: the occurrence of any event, change or other circumstances that could give rise to the termination of definitive agreements with respect to the Business Combination; the outcome of any legal proceedings that may be instituted against Supernova, the Company, the combined company or others following the announcement of the Business Combination and any definitive agreements with respect thereto; the inability to complete the Business Combination due to the failure to obtain approval of the stockholders of Supernova or to satisfy other conditions to closing; 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; the ability to meet stock exchange listing standards following the consummation of the Business Combination; the risk that the Business Combination disrupts current plans and operations of the Company as a result of the announcement and consummation of the Business Combination; the ability to recognize the anticipated benefits of the Business Combination, which may be affected by, among other things, competition, the ability of the combined company to grow and manage growth profitably, maintain relationships with customers and suppliers and retain its management and key employees; costs related to the Business Combination; changes in applicable laws or regulations; the ability to respond to general economic conditions; the health of the U.S. residential real estate industry; the ability to grow market share in existing markets or any new markets; the impact of the COVID-19 pandemic; the ability to manage growth effectively; the ability to accurately value and manage inventory, and to maintain an adequate and desirable supply of inventory; the ability to successfully launch new product and service offerings, and to manage, develop and refine the technology platform; and other risks and uncertainties set forth in the sections entitled “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements” in the registration statement on Form S-4 and proxy statement/prospectus discussed below and other documents filed by Supernova from time to time with the SEC. Supernova and the Company caution that the foregoing list of factors is not exclusive. 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 Supernova nor the Company undertakes any duty to update these forward-looking statements. Financial Information; Non-GAAP Financial Measures This Presentation also includes certain financial measures not presented in accordance with generally accepted accounting principles (“GAAP”) including, but not limited to, Contribution Margin, Adjusted EBITDA and certain ratios and other metrics derived therefrom. Contribution Margin means net sale proceeds less holding and selling costs, plus other services. Adjusted EBITDA includes adjustments for amortization of share based compensation, impairments and other non-cash expense. 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, cash flows from operations 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. Supernova 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. Supernova 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 and 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. 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, Supernova 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 and no reconciliation of the forward-looking non-GAAP financial measures is included.

Disclaimer (cont’d)  Use of Projections This Presentation contains financial forecasts for the Company with respect to certain financial results for the Company. Neither Supernova’s nor 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 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.   Industry and Market Data In this Presentation, Supernova and the Company rely on and refer to certain information and statistics obtained from third-party sources which they believe to be reliable. Neither Supernova nor the Company has independently verified the accuracy or completeness of any such third-party information.   Trademarks This Presentation may contain trademarks, service marks, trade names and copyrights of other companies, which are the property of their respective owners.
