Material Impairment Charges

In the fourth quarter of 2020, we announced a new Virtual First work model pursuant to which remote work will become the primary experience for all of our employees. As part of the Virtual First strategy, we will retain a portion of our office space to be used for team collaboration and a portion will be marketed for sublease. We reassessed our real estate asset groups and estimated the fair value of the office space to be subleased using current market conditions. Where the carrying value of the individual asset groups exceeded their fair value, an impairment charge was recognized for the difference. As a result, we recorded total impairment charges of $398.2 million in the fourth quarter of 2020 for right-of-use and other lease related assets. We have excluded this impairment charge from non-GAAP operating income and non-GAAP net income. We continue to expect to incur additional charges related to certain European leases over the next twelve months, which could range between $0 and $50 million depending on the then current market and economic conditions.

Share Repurchase Authorization

On February 12, 2021, the Board of Directors authorized Dropbox to repurchase an additional $1 billion of its Class A common stock. The repurchase is expected to be executed, subject to general business and market conditions and other investment opportunities, through open market purchases or privately negotiated transactions, including through Rule 10b5-1 plans.

(1) We calculate constant currency revenue growth rates by applying the prior period weighted average exchange rates to current period results.

(2) We calculate total annual recurring revenue ("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 our exchange rates used to calculate Total ARR on an annual basis, at the beginning of each fiscal year. We calculate constant currency Total ARR growth rates by applying the current period rate to prior period results.

(3) Non-GAAP diluted net income per share attributable to common stockholders is calculated based upon 416.1 million and 417.9 million diluted weighted-average shares of common stock for the three months ended December 31, 2020 and 2019, respectively.

(4) Non-GAAP diluted net income per share attributable to common stockholders is calculated based upon 419.3 million and 416.6 million diluted weighted-average shares of common stock for the fiscal year ended December 31, 2020 and 2019, respectively.

(1) Capital expenditures include cash outflows related to the build-out of our corporate headquarters in San Francisco, CA. Net cash provided by operating activities include tenant improvement allowances related to our corporate headquarters, and represents cash received from our landlord to partially offset this build-out. These amounts are presented net in the table above.

(2) As part of our acquisition of HelloSign in 2019, we have employee holdback agreements with key HelloSign personnel consisting of $48.5 million in cash payments subject to on-going employee service. The related expenses are recognized within research and development expenses over the required service period of three years. The payments began in the first quarter of 2020, and will be paid evenly in quarterly installments over the remaining required service period.

About Non-GAAP Financial Measures

To provide investors and others with additional information regarding Dropbox's results, we have disclosed the following non-GAAP financial measures: revenue growth and Total ARR growth excluding foreign exchange effect, which we refer to as on a constant currency basis, non-GAAP cost of revenue, non-GAAP gross profit, non-GAAP operating expenses (including research and development, sales and marketing and general and administrative), non-GAAP income from operations, non-GAAP net income, free cash flow ("FCF") and non-GAAP diluted net income per share. Dropbox has provided a reconciliation of each non-GAAP financial measure used in this earnings release to the most directly comparable GAAP financial measure. Non-GAAP cost of revenue, gross profit, operating expenses, income from operations, and net income differ from GAAP in that they exclude stock-based compensation expense, amortization of acquired intangible assets, other acquisition-related expenses, which include third-party diligence costs and expenses related to key employee holdback agreements, and impairment charges related to real estate assets. Non-GAAP net income also excludes net gains and losses on equity investments, and includes the income tax effect of the aforementioned adjustments. FCF differs from GAAP net cash provided by operating activities in that it treats capital expenditures as a reduction to net cash provided by operating activities. Free cash flow margin is calculated as FCF divided by revenue. Non-GAAP diluted net income per share differs from GAAP diluted net loss per share in that the numerator utilizes the non-GAAP net income as described above, and the weighted average shares used in the computation include certain shares that are excluded from the GAAP diluted net loss per share calculation because their effect would have been anti-dilutive. For periods that we are in a GAAP net income position, the weighted average shares used in the computation are the same as the shares used in our non-GAAP diluted net income per share computation. In order to present revenue on a constant currency basis for the fiscal year and quarter ended December 31, 2020, Dropbox calculates constant currency revenue growth rates by applying the prior period weighted average exchange rates to current period results. Dropbox calculates constant currency Total ARR growth rates by applying the current period rate to prior period results. Dropbox presents constant currency information to provide a framework for assessing how our underlying business performed excluding the effect of foreign currency rate fluctuations.

Dropbox's management uses these non-GAAP financial measures to understand and compare operating results across accounting periods, for internal budgeting and forecasting purposes, for short and long-term operating plans, and to evaluate Dropbox's financial performance and the ability to generate cash from operations. Management believes these non-GAAP financial measures reflect Dropbox's ongoing business in a manner that allows for meaningful period-to-period comparisons and analysis of trends in Dropbox's business, as they exclude expenses that are not reflective of ongoing operating results. Management also believes that these non-GAAP financial measures provide useful supplemental information to investors and others in understanding and evaluating Dropbox's operating results and future prospects in the same manner as management and in comparing financial results across accounting periods and to those of peer companies.

We believe that the non-GAAP financial measures, non-GAAP cost of revenue, gross profit, operating expenses, income from operations, net income, and diluted net income per share are meaningful to investors because they help identify underlying trends in our business that could otherwise be masked by the effect of the expenses that we exclude.

We believe that FCF is an indicator of our liquidity over the long term, and provides useful information regarding cash provided by operating activities and cash used for investments in property and equipment required to maintain and grow our business. FCF is presented for supplemental informational purposes only and should not be considered a substitute for financial information presented in accordance with GAAP. FCF has limitations as an analytical tool, and it should not be considered in isolation or as a substitute for analysis of other GAAP financial measures, such as net cash provided by operating activities. Some of the limitations of FCF are that FCF does not reflect our future contractual commitments, excludes investments made to acquire assets under finance leases, includes capital expenditures related to our corporate headquarters, and may be calculated differently by other companies in our industry, limiting its usefulness as a comparative measure.

The use of non-GAAP cost of revenue, gross profit, operating expenses, income from operations, net income, free cash flow, and diluted net income per share measures has certain limitations as they do not reflect all items of income, expense, and cash expenditures, as applicable, that affect Dropbox's operations. Dropbox mitigates these limitations by reconciling the non-GAAP financial measures to the most comparable GAAP financial measures. Additionally, we have provided supplemental disclosures in our reconciliation of net cash provided by operating activities to free cash flow to include capital expenditures related to our corporate headquarters, net of tenant improvement allowances and key employee holdback payments related to the acquisition of HelloSign. These non-GAAP financial measures should be considered in addition to, not as a substitute for or in isolation from, measures prepared in accordance with GAAP. Further, these non-GAAP measures may differ from the non-GAAP information used by other companies, including peer companies, and therefore comparability may be limited. Management encourages investors and others to review Dropbox's financial information in its entirety and not rely on a single financial measure.
