Disclaimer Certain statements in this Investor Update 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, including expected financial results for the second quarter of 2025 and the first half of 2025, trends and expectations regarding our business and operating results, including the implementation and potential impact of our NEXT initiative, our expectations on Verified Neighbor growth, 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 Update, 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; the impact of macroeconomic conditions on our business, including the impact of significant political, trade and regulatory developments; 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; risks associated with the use of AI and ML-driven features in our platform; 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 applicable laws and regulations; and other general market, political, economic, and business conditions. 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, 2025, filed on May 7, 2025, 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 Update 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 Update. This Investor Update 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 Investor Update to their nearest GAAP equivalent is included in the Appendix to this Investor Update. 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. 3

Revenue 30Some figures may not tie due to rounding. Large advertisers spent less, other channels continue to show growth: Q1 revenue was $54M, +2% year-over-year. Large advertiser spend down year-over-year as we prepare to unlock programmatic budgets. Together, all other channels showed double digit year-over-year growth in Q1. Performance optimization features continue to drive impact.

Net Income (Loss) 31 Net loss includes restructuring costs of $11M in Q4'23 and $26M in Q2'24. Some figures may not tie due to rounding.

Lower Q2 ad impression supply due to NEXT feed design updates. These changes are deliberate and focus on long-term retention. We expect Q2 operating expenses will remain approximately flat y/y1.

41 To supplement our condensed consolidated financial statements, which are prepared in accordance with GAAP, we present non-GAAP adjusted EBITDA and adjusted EBITDA margin in this Investor Update. Our use of non-GAAP financial measures has limitations as an analytical tool, and these measures should not be considered in isolation or as a substitute for analysis of financial results as reported under GAAP. We use these non-GAAP financial measures in conjunction with financial measures prepared in accordance with GAAP for planning purposes, including in the preparation of our annual operating budget, as a measure of our core operating results and the effectiveness of our business strategy, and in evaluating our financial performance. These measures provide consistency and comparability with past financial performance, facilitate period-to-period comparisons of core operating results, and also facilitate comparisons with other peer companies, many of which use similar non-GAAP financial measures to supplement their GAAP results. In addition, adjusted EBITDA is widely used by investors and securities analysts to measure a company's operating performance. We exclude the following items from one or more of our non-GAAP financial measures: stock-based compensation expense (non-cash expense calculated by companies using a variety of valuation methodologies and subjective assumptions), depreciation and amortization (non-cash expense), interest income, provision for income taxes, and, if applicable, restructuring charges and acquisition-related costs. Investors are cautioned that there are material limitations associated with the use of non-GAAP financial measures as an analytical tool. In particular, (1) stock-based compensation expense has recently been, and will continue to be for the foreseeable future, a significant recurring expense for our business and an important part of our compensation strategy, (2) although depreciation and amortization expense are non-cash charges, the assets subject to depreciation and amortization may have to be replaced in the future, and our non-GAAP measures do not reflect cash capital expenditure requirements for such replacements or for new capital expenditure requirements, and (3) adjusted EBITDA does not reflect: (a) changes in, or cash requirements for, our working capital needs; (b) interest expense (if any), or the cash requirements necessary to service interest or principal payments on debt (if any), which reduces cash available to us; or (c) tax payments that may represent a reduction in cash available to us. The non-GAAP measures we use may be different from non-GAAP financial measures used by other companies, limiting their usefulness for comparison purposes. We compensate for these limitations by providing specific information regarding the GAAP items excluded from these non-GAAP financial measures. A reconciliation of these non-GAAP measures has been provided on the following page. Non-GAAP Financial Measures
