#1◆Dropbox Company Presentation August 2021#2Safe Harbor Statement This presentation contains forward-looking statements. These statements may relate to, but are not limited to, plans for growth, technological capabilities and new features and products and the long-term financial targets of Dropbox, Inc. ("Dropbox," "we," "us," or similar terms), as well as assumptions relating to the foregoing. Forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified. In some cases, you can identify forward-looking statements by terminology such as "may," "will," "should," "could," "expect," "plan," anticipate," "believe," "estimate," "predict," "intend," "potential," "would," "continue," "ongoing" or the negative of these terms or other comparable terminology. You should not put undue reliance on any forward-looking statements. Forward-looking statements should not be read as a guarantee of future performance or results, and will not necessarily be accurate indications of the times at, or by, which such performance or results will be achieved, if at all. Forward-looking statements are based on information available at the time those statements are made or management's good faith beliefs and assumptions as of that time with respect to future events, and are subject to risks and uncertainties that could cause actual performance or results to differ materially from those expressed in, or suggested by, the forward-looking statements. In light of these risks and uncertainties, the events and circumstances contemplated by the forward-looking statements made in this presentation may not occur and actual results could differ materially from those anticipated or implied in the forward- looking statements. These risks and uncertainties are described in greater detail under the heading "Risk Factors" in our quarterly report on Form 10-Q for the fiscal quarter ended March 31, 2021 that we filed with the Securities and Exchange Commission (the "SEC") on May 7, 2021, and include, but are not limited to, our ability to realize anticipated benefits to our business from our shift to a Virtual First work model as well as impact to our financial results and business operations as a result of this shift; the impact to our financial results, business operations, the business of our customers, suppliers, partners and the economy as a result of the COVID-19 pandemic and related public health measures, as well as the potential for a more permanent global shift to remote work; our ability to retain and upgrade paying users, in particular paying users impacted by the COVID-19 pandemic, and increase our recurring revenue; our ability to attract new users or convert registered users to paying users, in particular prospective paying users financially impacted by the COVID-19 pandemic; our future financial performance, including trends in revenue, costs of revenue, gross profit or gross margin, operating expenses, paying users, and free cash flow; our history of net losses and our ability to achieve or maintain profitability; our liability for any unauthorized access to our data or our users' content, including through privacy and data security breaches, significant disruption of service on our platform or loss of content, particularly from any potential disruptions in the supply chain for hardware necessary to offer our services that may result from the COVID-19 pandemic,; any decline in demand for our platform or for content collaboration solutions in general; changes in the interoperability of our platform across devices, operating systems, and third-party applications that we do not control; competition in our markets; our ability to respond to rapid technological changes, extend our platform, develop new features or products, or gain market acceptance for such new features or products, particularly in light of potential disruptions to the productivity of our employees that may result from our shift to a Virtual First work model; our ability to manage our growth or plan for future growth; our acquisition of other businesses and the potential of such acquisitions to require significant management attention, disrupt our business, or dilute stockholder value; our ability to attract and retain key personnel and highly qualified personnel; our capital allocation plans with respect to our stock repurchase program and other investments;; and the dual class structure of our common stock and its effect of concentrating voting control with certain stockholders who held our capital stock prior to the completion of our initial public offering. These factors could cause actual results, performance or achievement to differ materially and adversely from those anticipated or implied in the forward-looking statements. Additional information will be available in other future reports that we may file with the SEC from time to time, which could cause actual results to vary from expectations. Except as required by law, Dropbox does not undertake any obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future developments or otherwise. In addition to financial information presented in accordance with U.S. generally accepted accounting principles ("GAAP"), this presentation includes certain non-GAAP financial measures, including non-GAAP gross margin, non-GAAP operating income, non-GAAP operating expenses (including research and development, sales and marketing and general and administrative), non-GAAP operating margin and free cash flow. These non-GAAP measures are presented for supplemental informational purposes only and should not be considered a substitute for financial information presented in accordance with GAAP. These non-GAAP measures have limitations as analytical tools, and they should not be considered in isolation or as a substitute for analysis of other GAAP financial measures. The non-GAAP measures Dropbox uses may differ from the non-GAAP measures used by other companies.

We calculate Total ARR as the number of users who have active paid licenses for access to our platform as of the end of the period, multiplied by their annualized subscription price to our platform. We adjust the exchange rates used to calculate Total ARR on an annual basis at the beginning of each fiscal year. Average Revenue per Paying User, (“ARPU”) – is defined as our revenue for the period presented divided by the average paying users during the same period. For interim periods, we use annualized revenue, which is calculated by dividing the revenue for the particular period by the number of days in that period and multiplying this value by 365 days. Average paying users are calculated based on adding the number of paying users as of the beginning of the period to the number of paying users as of the end of the period, and then dividing by two. Paying Users are defined as the number of users who have active paid licenses for access to our platform as of the end of the period. One person would count as multiple paying users if the person had more than one active license. For example, a 50-person Dropbox Business team would count as 50 paying users, and an individual Dropbox Plus user would count as one paying user. If that individual Dropbox Plus user was also part of the 50-person Dropbox Business team, we would count the individual as two paying users. 35#36Non-GAAP reconciliation Income from operations - GAAP Stock-based compensation Acquisition-related and other expenses Amortization of acquired intangible assets Workforce reduction expense Income from operations - Non-GAAP Non-GAAP operating margin $ $ Three Months Ended June 30, 2020 12.8 76.6 4.4 2.4 96.2 20.6% $ $ June 30, 2021 84.4 73.9 6.7 3.5 0.9 169.4 31.9% 36#37Non-GAAP reconciliation Net Cash provided by operating activities Capital expenditures Free cash flow $ $ December 31, 2018 425.4 (63.0) 362.4 Twelve Months Ended December 31, 2019 528.5 (136.1) 392.4 $ $ $ December 31, 2020 570.8 (80.1) 490.7 37#38Non-GAAP reconciliation Gross profit Gross margin Research and development Research and development margin Sales and marketing Sales and marketing margin General and administrative General and administrative margin Impairment related to real estate assets Impairment related to real estate assets margin Income (loss) from operations Operating margin Note: % may not foot due to rounding $ GAAP 1,499.3 78.3 % 727.5 38.0 % 422.8 22.1% 227.8 11.9 % 398.2 20.8 % (277.0) (14.5%) $ Stock based compensation 17.1 0.9 % (174.1) (9.1%) (33.7) (1.8%) (36.6) (1.9%) 261.5 13.7% Twelve Months Ended - 2020 Acquisition- related and other expenses $ (16.8) (0.9%) (0.1) 16.9 0.9 % Amortization of acquired intangible assets 3.9 $ 0.2 % $ (5.6) (0.3%) 9.5 0.5 % Impairment related to real estate assets (398.2) (20.8%) 398.2 20.8 % $ Non-GAAP 1,520.3 79.4% 536.6 28.0% 383.5 20.0 % 191.1 10.0 % - % 409.1 21.4% 38#39Non-GAAP reconciliation Gross profit Gross margin Research and development Research and development margin Sales and marketing Sales and marketing margin General and administrative General and administrative margin Income (loss) from operations Operating margin Note: % may not foot due to rounding $ GAAP 1,250.3 75.3% 662.1 39.9% 423.3 25.5 % 245.4 14.8 % (80.5) (4.8) % $ Twelve Months Ended - 2019 Stock based compensation 15.8 1.0 % (147.6) (8.9) % (31.4) (1.9) % (66.4) (4.0%) 261.2 15.7 % Acquisition-related and other expenses $ (14.5) (0.9) % (1.4) (0.1%) 15.9 1.0% Amortization of acquired intangible assets 3.4 $ 0.2 % (5.0) (0.3%) 8.4 0.5 % Non-GAAP 1,269.5 76.4% 500.0 30.1% 386.9 23.3% 177.6 10.7% 205.0 12.3% 39#40Non-GAAP reconciliation Gross profit Gross margin Research and development Research and development margin Sales and marketing Sales and marketing margin General and administrative General and administrative margin Income (loss) from operations Operating margin Note: % may not foot due to rounding $ GAAP 997.0 71.6 % 768.2 55.2% 439.6 31.6% 283.2 20.3 % (494.0) (35.5)% $ Twelve Months Ended - 2018 Stock based compensation 47.0 3.4 % (368.2) (26.5)% (94.3) (6.7)% (140.6) (10.0)% 650.1 46.7 % Employer payroll related to the release of two-tier RSUS $ 1.1 $ 0.1 % (8.3) (0.6%) (2.2) (0.2)% (2.3) (0.2%) 13.9 1.0 % Non-GAAP 1,045.1 75.1 % 391.7 28.1 % 343.1 24.7 % 140.3 10.1 % 170.0 12.2 % 40#41Non-GAAP reconciliation Loss from operations - GAAP Stock-based compensation Employer payroll taxes related to the release of two- teir RSUS Acquisition-related and other expenses Amortization of acquired intangible assets Impairement related to real estate assets Income from operations - Non-GAAP $ $ 2018 (494.0) $ 650.1 13.9 Twelve Months Ended 2019 170.0 $ (80.5) $ 261.2 15.9 8.4 205.0 $ 2020 (277.0) 261.5 16.9 9.5 398.2 409.1 41#42*Dropbox
