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: our limited operating history under our current business model; our ability to manage our growth effectively; the rate of growth in the market for analytics products
and services; our ability to attract new customers and expand sales to 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; our ability to develop, maintain, and enhance our brand and reputation cost-effectively; our ability to expand our sales force and the
effectiveness of our sales force; our ability to establish and maintain successful relationships with our channel partners; risks associated with our international operations; litigation and related costs; and other general market,
political, economic and business conditions. 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” sections of Alteryx’s Quarterly Report on Form 10-Q. 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.
Any unreleased services or features referenced in this or other presentations, press releases or public statements are only intended to outline Alteryx’s general product direction. They are intended for information purposes only,
and may not be incorporated into any contract. This is not a commitment to deliver any material, code, or functionality (which may not be released on time or at all) and customers should not rely upon this presentation or any such

Note: The chart above reflects annualized revenue from subscriptions for the group of customers that became customers in each respective cohort year. A cohort is a grouping of customers by the year specified. We calculate initial annualized revenue from subscriptions for any given cohort year as the
sum of the revenue from subscriptions from each customer in the cohort one month after the subscription start date in the initial period, multiplied by 12. In the chart above, this value is then normalized to the value of 1.0x to represent the base year for such cohort. We calculate annualized revenue
from subscriptions from subsequent years for any cohort as the sum of the total annual revenue from subscriptions in the period. The increase in annualized revenue from subscriptions for each of our 2014 and 2015 cohorts represents the increase in revenue in 2016 from the initial period of the
applicable cohort. For example, the 2.7 times increase for the 2014 cohort represents the result obtained by dividing the annualized revenue from subscriptions generated by the 2014 cohort in 2016 by the annualized revenue from subscriptions generated by the 2014 cohort in 2014, the initial period.

Our dollar-based net revenue retention rate is a trailing four-quarter average of the subscription revenue from a cohort of
customers in a quarter as compared to the same quarter in the prior year. Dollar-based net revenue retention rate equal to
100% would indicate that we received the same amount of revenue from our cohort of customers in the current quarter as
we did in the same quarter of the prior year. Dollar-based net revenue retention rate less than 100% would indicate that we
received less revenue from our cohort of customers in the current quarter than we did in the same quarter of the prior year.
To calculate our dollar-based net revenue retention rate, we first identify a cohort of customers (the “Base Customers”) in a
particular quarter (the “Base Quarter”). A customer will not be considered a Base Customer unless such customer has an active
subscription for the entirety of the Base Quarter. We then divide the revenue in the same quarter of the subsequent year
attributable to the Base Customers (the “Comparison Quarter”), including Base Customers from which we no longer derive
revenue in the Comparison Quarter, by the revenue attributable to that Base Customers in the Base Quarter. Our dollar-based
net revenue retention rate in a particular quarter is then obtained by averaging the result from that particular quarter by the
corresponding result from each of the prior three quarters.The dollar-based net revenue retention rate excludes revenue from
professional services from that cohort.
