Snap Inc Investor Presentation Deck

Snap Inc. Disclaimers Note Regarding User Metrics and Other Data We define a Daily Active User, or DAU, as a registered Snapchat user who opens the Snapchat application at least once during a defined 24-hour period. We calculate average DAUS for a particular quarter by adding the number of DAUS on each day of that quarter and dividing that sum by the number of days in that quarter. DAUS are broken out by geography because markets have different characteristics. We define average revenue per user, or ARPU, as quarterly revenue divided by the average DAUS. For purposes of calculating ARPU, revenue by user geography is apportioned to each region based on our determination of the geographic location in which advertising impressions are delivered, as this approximates revenue based on user activity. This allocation differs from our components of revenue disclosure in the notes to our consolidated financial statements, where revenue is based on the billing address of the advertising customer. For information concerning these metrics as measured by us, see "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our Quarterly Report on Form 10-Q for the quarter ended June 30, 2020 filed with the U.S. Securities and Exchange Commission, or the SEC, which is available on the SEC's website at www.sec.gov. Unless otherwise stated, statistical information regarding our users and their activities is determined by calculating the daily average of the selected activity for the most recently completed quarter included in this presentation. While these metrics are determined based on what we believe to be reasonable estimates of our user base for the applicable period of measurement, there are inherent challenges in measuring how our products are used across large populations globally. For example, there may be individuals who have unauthorized or multiple Snapchat accounts, even though we forbid that in our Terms of Service and implement measures to detect and suppress that behavior. We have not determined the number of such multiple accounts. Changes in our products, infrastructure, mobile operating systems, or metric tracking system, or the introduction of new products, may impact our ability to accurately determine active users or other metrics and we may not determine such inaccuracies promptly. We also believe that we don't capture all data regarding each of our active users. Technical issues may result in data not being recorded from every user's application. For example, because some Snapchat features can be used without internet connectivity, we may not count a DAU because we don't receive timely notice that a user has opened the Snapchat application. This undercounting may grow as we grow in Rest of World markets where users may have poor connectivity. We do not adjust our reported metrics to reflect this underreporting. We believe that we have adequate controls to collect user metrics, however, there is no uniform industry standard. We continually seek to identify these technical issues and improve both our accuracy and precision, including ensuring that our investors and others can understand the factors impacting our business, but these and new issues may continue in the future, including if there continues to be no uniform industry standard. Some of our demographic data may be incomplete or inaccurate. For example, because users self-report their dates of birth, our age-demographic data may differ from our users' actual ages. And because users who signed up for Snapchat before June 2013 were not asked to supply their date of birth, we exclude those users and estimate their ages based on a sample of the self-reported ages we do have. If our active users provide us with incorrect or incomplete information regarding their age or other attributes, then our estimates may prove inaccurate and fail to meet investor expectations. See https://businesshelp.snapchat.com/ for details. In the past we have relied on third-party analytics providers to calculate our metrics, but today we rely primarily on our analytics platform that we developed and operate. We count a DAU only when a user opens the application and only once per user per day. We believe this methodology more accurately measures our user engagement. We have multiple pipelines of user data that we use to determine whether a user has opened the application during a particular day, and thus is a DAU. This provides redundancy in the event one pipeline of data were to become unavailable for technical reasons, and also gives us redundant data to help measure how users interact with our application. If we fail to maintain an effective analytics platform, our metrics calculations may be inaccurate. We regularly review, have adjusted in the past, and are likely in the future to adjust our processes for calculating our internal metrics to improve their accuracy. As a result of such adjustments, our DAUS or other metrics may not be comparable to those in prior periods. Our measures of DAUS may differ from estimates published by third parties or from similarly titled metrics of our competitors due to differences in methodology or data used. 2
