#1May 2023 nextdoor#2Disclaimer Certain statements in this presentation may be considered "forward-looking statements" within the meaning of the "safe harbor" provisions of the U.S. Private Securities Litigation Reform Act of 1995. In some cases, you can identify forward-looking statements by terminology such as "may," "should," "expect," "intend," "will," "estimate,” “anticipate," "believe," "predict," "project,” “target," "plan," or "potentially" or the negatives of these terms or variations of them or similar terminology. These statements include, but are not limited to, statements regarding our future performance and our market opportunity, our business strategy and plans, and our objectives and future operations, including our expansion into new markets. Forward-looking statements are based upon various estimates and assumptions, as well as information known to us as of the date of this investor presentation, and are subject to risks and uncertainties. Accordingly, actual results could differ materially due to a variety of factors, including: our ability to scale our business and monetization efforts; our ability to expand business operations abroad; our limited operating history; risks associated with managing our growth; our ability to achieve and maintain profitability in the future; the effects of the highly competitive market in which we operate; our ability to attract new and retain existing customers and users, or renew and expand our relationships with them; our ability to anticipate and satisfy customer preferences; market acceptance of our platform; our ability to successfully develop and timely introduce new products and services; our ability to achieve our objectives of strategic and operational initiatives; cybersecurity risks to our various systems and software; the impact of privacy and data security laws; and other general market, political, economic, and business conditions, including those related to inflation, rising interest rates and the ongoing COVID-19 pandemic. Additional risks and uncertainties that could affect our financial results and business are more fully described in our Quarterly Report on Form 10-Q for the period ended March 31, 2023, filed with the SEC on May 9, 2023, and our other SEC filings, which are available on the Investor Relations page of our website at investors.nextdoor.com and on the SEC's website at www.sec.gov. All forward-looking statements contained herein are based on information available to us as of the date hereof and you should not rely upon forward-looking statements as predictions of future events. The events and circumstances reflected in the forward-looking statements may not be achieved or occur. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, performance, or achievements. We undertake no obligation to update any of these forward-looking statements for any reason after the date of this investor presentation or to conform these statements to actual results or revised expectations, except as required by law. Undue reliance should not be placed on the forward-looking statements in this investor presentation. This presentation includes certain non-GAAP financial measures (including on a forward-looking basis). These non-GAAP measures are in addition to, and not a substitute for or superior to, measures of financial performance prepared in accordance with GAAP and should not be considered as an alternative to their nearest GAAP equivalent or any other performance measures derived in accordance with GAAP. A reconciliation of the non-GAAP financial measures used in this Presentation to their nearest GAAP equivalent is included in the Appendix to this Presentation. Nextdoor believes that these non-GAAP measures of financial results (including on a forward-looking basis) provide useful supplemental information to investors about Nextdoor. Nextdoor's management uses forward-looking non-GAAP measures to evaluate Nextdoor's projected financials and operating performance. However, there are a number of limitations related to the use of these non-GAAP measures and their nearest GAAP equivalents, including that they exclude significant expenses that are required by GAAP to be recorded in Nextdoor's financial measures. In addition, other companies may calculate non-GAAP measures differently, or may use other measures to calculate their financial performance, and therefore, Nextdoor's non-GAAP measures may not be directly comparable to similarly titled measures of other companies. Additionally, to the extent that forward-looking non-GAAP financial measures are provided, they are presented on a non-GAAP basis without reconciliations of such forward-looking non-GAAP measures due to the inherent difficulty in forecasting and quantifying certain amounts that are necessary for such reconciliations. 2#3Nextdoor is the neighborhood network 11 Countries >80M Verified Neighbors (VNS) Metrics as of 3/31/2023. 1 in 3 U.S. Households 42M Weekly Active Neighbors (WAU) Network effects with online & offline connection is unique Each social link is highly valuable because most commerce is local Secular shift towards digital advertising, future new revenue models Many vectors for sustained revenue growth High barrier to entry: network difficult & time consuming to build Only digital neighborhood network: purpose-driven & authentic Proven team: set up for growth at scale 3#4Q1'23 highlights 16% YoY WAU growth >70% of VNs in the U.S. joined organically ~90% Retention of top 50 advertisers Verified Neighbors and WAU as of 3/31/2023.
