Financial Outlook
As of February 9, 2021, guidance for the first quarter of 2021 and full year 2021 is as follows:
 
First Quarter 2021 Guidance:
Revenue is expected to be in the range of $104.0 million to $107.0 million.
Non-GAAP loss from operations is expected to be in the range of $(21.0) million to $(18.0) million.
Non-GAAP net loss per share is expected to be in the range of $(0.25) to $(0.22) based on approximately 67.5 million non-GAAP weighted-average basic and diluted shares outstanding.
Full Year 2021 Guidance:
Revenue is expected to be in the range of $555.0 million to $565.0 million.
ARR is expected to be approximately $625.0 million as of December 31, 2021.
Non-GAAP income (loss) from operations is expected to be in the range of $(5.0) million to $5.0 million.
Non-GAAP net income (loss) per share is expected to be in the range of $(0.07) to $0.07 based on approximately 68.5 million and 72.0 million non-GAAP weighted-average diluted shares outstanding, respectively, and an effective tax rate of 20%.
The financial outlook above for non-GAAP income (loss) from operations and non-GAAP net income (loss) per share excludes estimates for stock-based compensation expense, acquisition-related adjustments, and amortization of debt discount and issuance costs. A reconciliation of the non-GAAP financial guidance measures to corresponding GAAP measures is not available on a forward-looking basis primarily as a result of the uncertainty regarding, and the potential variability of, stock-based compensation expense, acquisition-related adjustments, and amortization of debt discount and issuance costs. In particular, stock-based compensation expense is impacted by our future hiring and retention needs, as well as the future fair market value of our Class A common stock, all of which is not within our control, is difficult to predict, and is subject to constant change. The actual amount of these expenses during 2021 will have a significant impact on our future GAAP financial results. Accordingly, a reconciliation of the non-GAAP financial guidance measures to the corresponding GAAP measures is not available without unreasonable effort.

Non-GAAP Financial Measures and Operating Measures
Non-GAAP Financial Measures. To supplement our consolidated financial statements, which are prepared and presented in accordance with GAAP, we use the following non-GAAP financial measures: non-GAAP gross profit, non-GAAP gross margin, non-GAAP income (loss) from operations, non-GAAP net income (loss), non-GAAP net income (loss) per diluted share, and non-GAAP weighted-average diluted shares outstanding. The presentation of these financial measures is not intended to be considered in isolation or as a substitute for, or superior to, financial information prepared and presented in accordance with GAAP.
We use non-GAAP measures to internally evaluate and analyze financial results. We believe these non-GAAP financial measures provide investors with useful supplemental information about the financial performance of our business, enable comparison of financial results between periods where certain items may vary independent of business performance, and enable comparison of our financial results with other public companies, many of which present similar non-GAAP financial measures. We exclude the following items from one or more of our non-GAAP financial measures:
Stock-based compensation expense. We exclude stock-based compensation expense, which is a non-cash expense, from certain of our non-GAAP financial measures because we believe that excluding this item provides meaningful supplemental information regarding operational performance. In particular, companies calculate stock-based compensation expense using a variety of valuation methodologies and subjective assumptions.
Acquisition-related adjustments. We exclude amortization and impairment of intangible assets and changes in fair value of contingent consideration, which are non-cash and related to business combinations from certain of our non-GAAP financial measures. We exclude such expenses as they are related to a business combination and have no direct correlation to the operation of our business.
Convertible senior notes adjustments. We exclude the loss on induced conversion and loss on debt extinguishment and the portion of amortization of debt discount and issuance costs that relate to the equity component of our convertible notes, which are non-cash, from certain of our non-GAAP financial measures. We exclude such expenses as they are non-cash and have no direct correlation to the operation of our business.
Income tax adjustments. We utilize a fixed projected long-term non-GAAP tax rate in order to provide better consistency across reporting periods by eliminating the effects of items such as changes in the tax valuation allowance, excess tax benefits associated with stock options, and tax effects of acquisition-related costs, since each of these can vary in size and frequency. When projecting this rate, we exclude the direct impact of the following non-cash items: stock-based compensation expenses, amortization and impairment of purchased intangibles, the amortization of debt discount and issuance costs, and the loss on induced conversion and debt extinguishment. The projected rate also assumes no new acquisitions, and considers other factors, including our expected tax structure, our tax positions in various jurisdictions and key legislation in major jurisdictions where we operate. We used a projected non-GAAP tax rate of 20% for each of 2020 and 2019. We anticipate using a long-term non-GAAP tax rate of 20% for the year ending December 31, 2021; however, the non-GAAP tax rate could be subject to change for a variety of reasons, including the rapidly evolving global tax environment, significant changes in our geographic earnings mix, including due to acquisition activity, or other changes to our strategy or business operations. We will re-evaluate our long-term rate as appropriate.
Investors are cautioned that there are material limitations associated with the use of non-GAAP financial measures as an analytical tool. In particular, we exclude stock-based compensation expense, amortization of intangible assets, and amortization of debt discount and issuance costs which are recurring and will be reflected in our financial results for the foreseeable future. The non-GAAP measures we use may be different from non-GAAP financial measures used by other companies, limiting their usefulness for comparison purposes. We compensate for these limitations by providing specific information regarding the GAAP items excluded from these non-GAAP financial measures.

Annual Recurring Revenue (ARR). Annual recurring revenue, or ARR, represents the total annual contract value for active customer subscription contracts as of the measurement date. We also use ARR as one of our operating measures to assess the health and trajectory of our business. ARR should be viewed independently of revenue and deferred revenue as ARR is a performance metric and is not intended to be a substitute for, or combined with, any of these items.

Number of Customers. We define a customer at the end of any particular period as an entity with a subscription agreement that runs through the current or future period as of the measurement date. Organizations with free trials have not entered into a subscription agreement and are not considered customers. A single organization with separate subsidiaries, segments, or divisions that use our platform may represent multiple customers, as we treat each entity that is invoiced separately as a single customer. In cases where customers subscribe to our platform through our channel partners, each end customer is counted separately.

Dollar-Based Net Expansion Rate.  Our dollar-based net expansion rate is a trailing four-quarter average of the annual contract value, or ACV, which is defined as the subscription revenue that we would contractually expect to recognize over the term of the contract divided by the term of the contract, in years, from a cohort of customers in a quarter as compared to the same quarter in the prior year. To calculate our dollar-based net expansion rate, we first identify a cohort of customers, or the Base Customers, in a particular quarter, or the Base Quarter. A customer will not be considered a Base Customer unless such customer has an active subscription on the last day of the Base Quarter. We then divide the ACV in the same quarter of the subsequent year attributable to the Base Customers, or the Comparison Quarter, including Base Customers from which we no longer derive ACV in the Comparison Quarter, by the ACV attributable to those Base Customers in the Base Quarter. Our dollar-based net expansion rate in a particular quarter is then obtained by averaging the result from that particular quarter with the corresponding result from each of the prior three quarters. The dollar-based net expansion rate excludes contract value relating to professional services from that cohort.

Annual Recurring Revenue (ARR). ARR represents the annualized recurring value of all active subscription contracts at the end of a reporting period and excludes the value of non-recurring revenue streams, such as professional services. Both multi-year contracts and contracts with terms less than one year are annualized by dividing the total committed contract value by the number of months in the subscription term and then multiplying by twelve (in millions).
