Nextdoor Holdings, Inc.

Our business is subject to numerous risks and uncertainties, including those described in Part I, Item 1A, “Risk Factors” in this Annual Report. You should carefully consider these risks and uncertainties when investing in our Class A common stock. Some of the principal risks and uncertainties include the following:

•We have a limited operating history at the current scale of our business and are still scaling up our monetization efforts, which makes it difficult to evaluate our current business and future prospects, and there is no assurance we will be able to scale our business for future growth.

•Adverse global economic and financial conditions could harm our business and financial condition.

•We currently generate substantially all of our revenue from advertising. If advertisers reduce or eliminate their spending with us, our business, operating results, and financial condition would be adversely impacted.

•Our business is highly competitive. Competition presents an ongoing threat to the success of our business.

•Our business is dependent on our ability to maintain and scale our product offerings and technical infrastructure, and any significant disruption in the availability of our platform could damage our reputation, result in a potential loss of neighbors and engagement, and adversely affect our business, operating results, and financial condition.

•If we fail to scale our business effectively, our business, operating results, and financial condition would be adversely affected.

•We may not be successful in our AI initiatives, which could adversely affect our business, reputation, or financial results.

•If our efforts to build strong brand identity and reputation are not successful, we may not be able to attract or retain neighbors, and our business, operating results, and financial condition will be adversely affected.

•Our business depends largely on our ability to attract, retain, and assimilate talented employees, including senior management. If we lose the services of or fail to successfully assimilate highly skilled personnel, key employees or members of our senior management team, we may not be able to execute on our business strategy.

•We are dependent on third-party software and service providers, including ads platforms and programmatic advertising partners, for management and delivery of certain advertisements on the Nextdoor platform. Any failure or interruption experienced by such third-parties could result in the inability of certain businesses to advertise on our platform, and adversely impact our business, operating results, and financial condition.

•We rely on third-party software and service providers, including Amazon Web Services (“AWS”), to provide systems, storage and services for our platform. Any failure or interruption experienced by such third parties could result in the inability of neighbors and advertisers to access or utilize our platform, and adversely impact our business, operating results, and financial condition.

•Technologies have been developed that can block the display of advertisements on the Nextdoor platform, which could adversely impact our business, operating results, and financial condition.

•Security breaches, including improper access to or disclosure of our data or our neighbors’ data, or other hacking and phishing attacks on our or third-party systems, could harm our reputation, adversely affect our business, and result in legal liability.

•Distribution and marketing of, and access to, our platform depends, in significant part, on a variety of third-party publishers and platforms (including mobile app stores, third-party payment providers, computer systems, and other communication systems and service providers). If these third parties limit, prohibit or otherwise interfere with or change the terms of the distribution, use or marketing of our platform in any material way, it could materially adversely affect our business, operating results, and financial condition.

•Certain of our market opportunities and key metric estimates could prove to be inaccurate, and have been inaccurate in the past, and any real or perceived inaccuracies may harm our reputation and negatively affect our business.

•We have a history of net losses and may experience net losses in the future and we cannot assure you that we will achieve or sustain profitability. If we cannot achieve and sustain profitability, our business, financial condition, and operating results will be adversely affected.

•We may have greater than anticipated tax liabilities, which could harm our business, revenue and financial results.

•We may be liable as a result of content or information that is published or made available on our platform.

•Our business is subject to complex and evolving U.S. and foreign laws, regulations, and industry standards, many of which are subject to change and uncertain interpretations, which uncertainty could harm our business, operating results, and financial condition.

•We are currently, and in the future may be, involved in legal disputes that are expensive and time consuming, and, if resolved adversely, could harm our business, operating results, and financial condition.

•The price of our Class A common stock has been and may continue to be volatile.

•The dual class structure of our common stock has the effect of concentrating voting power with our management and other existing stockholders, which will limit your ability to influence the outcome of important transactions, including a change in control.
