Safe Harbor This presentation includes “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements may be identified by the use of terminology such as “believe,” “may,” “will,” “intend,” “expect,” “plan,” “anticipate,” “estimate,” “potential,” or “continue,” or other comparable terminology. All statements other than statements of historical fact could be deemed forward-looking, including any projections of product availability, growth and financial metrics and any statements regarding product roadmaps, strategies, plans or use cases. Although Alteryx believes that the expectations reflected in any of these forward-looking statements are reasonable, these expectations or any of the forward-looking statements could prove to be incorrect, and actual results or outcomes could differ materially from those projected or assumed in the forward-looking statements, including, but not limited to, as a result of: the impact to the economy, our customers and our business due to the COVID-19 pandemic; our ability to manage our growth and the investments made to grow our business effectively; our ability to retain and expand our talent base, particularly our sales force and software engineers, and increase their productivity; our history of losses; our dependence on our software platform for substantially all of our revenue; our ability to attract new customers and expand sales to and retain existing customers; our ability to develop and release product and service enhancements and new products and services to respond to rapid technological change in a timely and cost-effective manner; intense and increasing competition in our market; the rate of growth in the market for analytics products and services; our ability to establish and maintain successful relationships with our channel partners; our dependence on technology and data licensed to us by third parties; risks associated with our international operations; our ability to develop, maintain, and enhance our brand and reputation cost effectively; litigation and related costs; security breaches; and other general market, political, economic and business conditions. Additionally, these forward-looking statements involve risk, uncertainties and assumptions, including those related to the impact of COVID-19 on our business and global economic conditions. Many of these assumptions relate to matters that are beyond our control and changing rapidly, including, but not limited to, the timeframes for and severity of the impact of COVID-19 on our customers’ purchasing decisions and the length of our sales cycles, particularly for customers in certain industries highly affected by COVID-19. Alteryx’s future financial condition and results of operations, as well as any forward-looking statements, are subject to risks and uncertainties, including but not limited to the factors set forth above, in Alteryx’s press releases, public statements and/or filings with the Securities and Exchange Commission, especially the “Risk Factors” section of Alteryx’s most recent Annual Report on Form 10-K. These documents and others containing important disclosures are available at www.sec.gov or in the “Investors” section of Alteryx’s website at www.alteryx.com. All forward-looking statements are made as of the date of this presentation and Alteryx assumes no obligation to update any such forward-looking statements. This presentation also contains estimates and other statistical data made by independent parties and by us relating to market size and growth and other data about our industry. This data involves a number of assumptions and limitations, and you are cautioned not to give undue weight to such estimates. In addition, projections, assumptions, and estimates of our future performance and the future performance of the markets in which we operate are necessarily subject to a high degree of uncertainty and risk. In addition to the financials presented in accordance with U.S. generally accepted accounting principles (GAAP), this presentation includes certain non-GAAP financial measures. The non-GAAP financial measures have limitations as analytical tools and you should not consider them in isolation or as a substitute for the most directly comparable financial measures prepared in accordance with GAAP. There are a number of limitations related to the use of these non-GAAP financial measures versus their nearest GAAP equivalents. Other companies, including companies in our industry, may calculate non-GAAP financial measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of our non-GAAP financial measures as tools for comparison. We urge you to review the reconciliation of our non-GAAP financial measures to the most directly comparable GAAP financial measures set forth in the Appendix, and not to rely on any single financial measure to evaluate our business.
