Use of Non-GAAP Financial Measures
2


To provide investors and others with additional information regarding Twilio’s results, the following non-GAAP financial measures are disclosed:
Non‑GAAP Gross Profit and Non‑GAAP Gross Margin. For the periods presented, Twilio defines non‑GAAP gross profit and non‑GAAP gross margin as GAAP gross profit and GAAP gross margin, respectively, adjusted to exclude, as applicable, certain expenses as presented in the table below.
Non‑GAAP Operating Expenses. For the periods presented, Twilio defines non‑GAAP operating expenses (including categories of operating expenses) as GAAP operating expenses (and categories of operating expenses) adjusted to exclude, as applicable, certain expenses as presented in the table below.
Non‑GAAP Income (Loss) from Operations and Non‑GAAP Operating Margin. For the periods presented, Twilio defines non‑GAAP income (loss) from operations and non‑GAAP operating margin as GAAP loss from operations and GAAP operating margin, respectively, adjusted to exclude, as applicable, certain expenses as presented in the table below.
Non-GAAP Tax Rate. The Company utilizes a fixed long-term projected non-GAAP tax rate in order to provide better consistency across the interim reporting periods by eliminating the effects of items that can vary in size and frequency. For fiscal 2020, the Company used a projected non-GAAP tax rate of 25%. For fiscal 2021, the Company uses a projected non-GAAP tax rate of 22%, which reflects currently available information, as well as other factors and assumptions. The non-GAAP tax rate could be subject to change for a variety of reasons, including the changes in tax laws and regulations, significant changes in the Company’s geographic earnings mix, or other changes to the Company’s strategy or business operations. The Company will re-evaluate its long-term rate as appropriate.
Non‑GAAP Net Income Attributable to Common Stockholders and Non‑GAAP Net Income Per Share Attributable to Common Stockholders, Basic and Diluted. For the periods presented, Twilio defines non-GAAP net income attributable to common stockholders and non‑GAAP net income per share attributable to common stockholders, basic and diluted, as GAAP net loss attributable to common stockholders and GAAP net loss per share attributable to common stockholders, basic and diluted, respectively, adjusted to exclude, as applicable, certain expenses presented in the table below.
Twilio’s management uses the foregoing non-GAAP financial information, collectively, to evaluate its ongoing operations and for internal planning and forecasting purposes. Twilio’s management believes that non-GAAP financial information, when taken collectively, may be helpful to investors because it provides consistency and comparability with past financial performance, facilitates period-to-period comparisons of results of operations, and assists in comparisons with other companies, many of which use similar non-GAAP financial information to supplement their GAAP results. Non‑GAAP financial information is presented for supplemental informational purposes only, should not be considered a substitute for financial information presented in accordance with generally accepted accounting principles, and may be different from similarly‑titled non‑GAAP measures used by other companies. Whenever Twilio uses a non-GAAP financial measure, a reconciliation is provided to the most closely applicable financial measure stated in accordance with GAAP. Investors are encouraged to review the related GAAP financial measures and the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measures.
With respect to Twilio’s guidance as provided under “Outlook” above, Twilio has not reconciled its expectations as to non-GAAP income (loss) from operations to GAAP loss from operations or non-GAAP net income (loss) per share to GAAP net loss per share because stock-based compensation expense cannot be reasonably calculated or predicted at this time. Accordingly, a reconciliation is not available without unreasonable effort.
Operating Metrics
Twilio reviews a number of operating metrics to evaluate its business, measure performance, identify trends, formulate business plans, and make strategic decisions. These include the number of Active Customer Accounts and Dollar-Based Net Expansion Rate.
Number of Active Customer Accounts. Twilio believes that the number of Active Customer Accounts is an important indicator of the growth of its business, the market acceptance of its platform and future revenue trends. Twilio defines an Active Customer Account at the end of any period as an individual account, as identified by a unique account identifier, for which Twilio has recognized at least $5 of revenue in the last month of the period. Twilio believes that use of its platform by customers at or above the $5 per month threshold is a stronger indicator of potential future engagement than trial usage of its platform or usage at levels below $5 per month. A single organization may constitute multiple unique Active Customer Accounts if it has multiple account identifiers, each of which is treated as a separate Active Customer Account. Effective December 31, 2019, we round down the number of Active Customer Accounts to the nearest thousand.
Dollar-Based Net Expansion Rate. Twilio’s ability to drive growth and generate incremental revenue depends, in part, on the Company’s ability to maintain and grow its relationships with existing Active Customer Accounts and to increase their use of the platform. An important way in which Twilio has historically tracked performance in this area is by measuring the Dollar-Based Net Expansion Rate for Active Customer Accounts. Twilio’s Dollar-Based Net Expansion Rate increases when such Active Customer Accounts increase their usage of a product, extend their usage of a product to new applications or adopt a new product. Twilio’s Dollar-Based Net Expansion Rate decreases when such Active Customer Accounts cease or reduce their usage of a product or when the Company lowers usage prices on a product. As our customers grow their businesses and extend the use of our platform, they sometimes create multiple customer accounts with us for operational or other reasons. As such, when we identify a significant customer organization (defined as a single customer organization generating more than 1% of revenue in a quarterly reporting period) that has created a new Active Customer Account, this new Active Customer Account is tied to, and revenue from this new Active Customer Account is included with, the original Active Customer Account for the purposes of calculating this metric. Twilio believes that measuring Dollar-Based Net Expansion Rate provides a more meaningful indication of the performance of the Company’s efforts to increase revenue from existing customers.
For historical periods through December 31, 2019, Twilio’s Dollar-Based Net Expansion Rate compared the revenue from Active Customer Accounts, other than large Active Customer Accounts that have never entered into 12-month minimum revenue commitment contracts with the Company, in a quarter to the same quarter in the prior year. For reporting periods starting with the three months ended March 31, 2020, Twilio's Dollar-Based Net Expansion Rate compares the total revenue from all Active Customer Accounts in a quarter to the same quarter in the prior year. To calculate the Dollar-Based Net Expansion Rate, the Company first identifies the cohort of Active Customer Accounts that were Active Customer Accounts in the same quarter of the prior year. The Dollar-Based Net Expansion Rate is the quotient obtained by dividing the revenue generated from that cohort in a quarter, by the revenue generated from that same cohort in the corresponding quarter in the prior year. When Twilio calculates Dollar-Based Net Expansion Rate for periods longer than one quarter, it uses the average of the applicable quarterly Dollar-Based Net Expansion Rates for each of the quarters in such period. As a result of the change in calculation of Dollar-Based Net Expansion Rate, unless specifically identified as being calculated based on total revenue, any Dollar-Based Net Expansion Rates disclosed by our Company in SEC filings, press releases and presentations prior to the date of our press release for the three months ended March 31, 2020, will not be directly comparable to our Dollar-Based Net Expansion Rates going forward.

(1) Effective December 31, 2019, we round down the number of active customer accounts to the nearest thousand. Commencing with the three month period ended March 31, 2019, Active Customer Accounts include the contribution from Twilio SendGrid customer accounts from February 1, 2019 (the date of the acquisition). Commencing with the three month period ended December 31, 2020, Active Customer Accounts include the contribution from Twilio Segment customer accounts from November 2, 2020 (the date of the acquisition).

(2) As previously announced in our Annual Report on Form 10-K filed with the SEC on March 2, 2020, commencing with the three-month period ended March 31, 2020, we calculate our Dollar-Based Net Expansion Rate by comparing total revenue from a cohort of Active Customer Accounts in a period to the same period in the prior year (the "New DBNE Definition"). To facilitate comparison between the periods presented, Dollar-Based Net Expansion Rate as presented in the table above, has been calculated as if the New DBNE Definition had been in effect during that period. As a result of the New DBNE Definition, unless specifically identified as being calculated using total revenue, any Dollar-Based Net Expansion Rates disclosed by our Company in SEC filings, press releases and presentations prior to the date of our press release for the three months ended March 31, 2020, will not be directly comparable to our Dollar-Based Net Expansion Rates going forward. Commencing with the three month period ended March 31, 2020, Dollar-Based Net Expansion Rate includes the contribution from Twilio SendGrid from February 1, 2019 (the date of the acquisition).

(3) After adjusting for the extra month of revenue from Twilio SendGrid in January 2020, Dollar-Based Net Expansion Rate was 135%.
