The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our condensed consolidated financial statements and related notes appearing elsewhere in this Quarterly Report on Form 10-Q. This discussion contains forward-looking statements that are based upon current plans, expectations, and beliefs that involve risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of various factors, including the impact of the COVID-19 pandemic and those other factors discussed in the section titled "Risk Factors" and in other parts of this Quarterly Report on Form 10-Q. OverviewCloudflare's mission is to help build a better Internet. We have built a global cloud platform that delivers a broad range of network services to businesses of all sizes and in all geographies-making them more secure, enhancing the performance of their business-critical applications, and eliminating the cost and complexity of managing individual network hardware. Our platform serves as a scalable, easy-to-use, unified control plane to deliver security, performance, and reliability across their on-premise, hybrid, cloud, and SaaS applications. Our Business Model Our business model benefits from our ability to serve the needs of all customers ranging from individual developers to the largest enterprises, in a cost-effective manner. Our products are easy to deploy and allow for rapid and efficient onboarding of new customers and expansion of our relationships with customers over time. Given the large customer base we have and the immense amount of Internet traffic that we manage, we are able to negotiate mutually beneficial agreements with Internet Service Providers (ISPs) that allow us to place our equipment directly in their data centers, which drives down our bandwidth and co-location expenses. This symbiotic relationship that we have with ISPs and the efficiency of our serverless network architecture allows us to introduce new products on our platform at low marginal cost.
We generate revenue primarily from sales to our customers of subscriptions to access our platform. We offer a variety of plans to our free and paying customers depending on their required features and functionality.
•Pay-As-You-Go Customers. For our pay-as-you-go customers (and which we previously referred to as self-serve customers), we offer Pro and Business subscription plans through our website per registered domain, and it is common for customers to purchase subscriptions to cover multiple Internet properties (e.g., domains, websites, application programming interfaces (APIs), and mobile applications). Our Pro plan provides basic functionality to improve the security, performance, and reliability of applications, such as enhanced web application firewall and image and mobile optimization. Our Business plan includes additional functionality often required by larger organizations, including service level agreements of up to 100% uptime, dynamic content acceleration, and enhanced customer support. Our implementation period for pay-as-you-go customers is extremely short with most customers implementing our services within a matter of minutes. While our Pro and Business plans offer significant value to customers, customers can subscribe to add-on products and platform functionality we offer to meet their more advanced needs. Our pay-as-you-go customers typically pay with a credit card on a monthly basis. •Contracted Customers. Our contracted customers, which consist of customers that enter into contracts for our Enterprise subscription plan (and which we previously referred to as enterprise customers), have contracts that range from one to three years and are typically billed on a monthly basis. Our contracted customer sales cycle typically lasts less than one quarter. Our agreements with contracted customers are tailored and priced to meet their varying needs and requirements. Enterprise subscription plan agreements for our contracted customers generally include a base subscription and a smaller portion based on usage. Key elements of our business model include: •Free customer base. Free customers are an important part of our business. These customers, like our pay-as-you-go customers, sign up for our service through our website and are typically individual developers, early stage startups, hobbyists, and other users. Our free customers create scale, serve as 38 -------------------------------------------------------------------------------- Table of contents efficient brand marketing, and help us attract developers, customers, and potential employees. These free customers expose us to diverse traffic, threats, and problems, often allowing us to see potential security, performance, and reliability issues at the earliest stage. This knowledge allows us to improve our products and deliver more effective solutions to our paying customers. In addition, the added scale and diversity of this traffic makes us valuable to a diverse set of global ISPs, improving the breadth and economic terms of our interconnections, bandwidth costs, and co-location expenses. Finally, the enthusiastic engagement of our free customer base represents a "virtual quality assurance" function that allows us to maintain a high rate of product innovation, while ensuring our products are extensively tested in real world environments before they are deployed to our paying customers. •Significant investment in ongoing product development. We invest significantly in research and development. Our focus on research and development allows us to continually enhance the capabilities and functionality of our global cloud platform with new products that are innovative and powerful and can be quickly adopted by our customers and helps us grow our free and paying customer base, which allows us to serve a greater portion of the world's Internet traffic. That in turn provides us with greater knowledge and insight into the challenges that Internet users face every day. •Investments in our network for growth. We believe that the size, sophistication, and distributed nature of our network provide us with a significant competitive advantage. We intend to continue to make substantial investments in network infrastructure to support the growth of our business. As we invest in our network, we believe the service that we can provide our customers and the insight and knowledge that we can gain will continue to grow. •Efficient go-to-market model. We have built an efficient go-to market model that reflects the flexibility and ease of use our platform offers to our customers around the world. This has enabled us to acquire new customers as well as to expand within our existing customer base in a rapid, cost-effective manner. In particular, we have invested heavily in our contracted customer sales efforts. •New customer acquisition. We believe that any person or business that relies on the Internet to deliver products, services, or content can be aCloudflare customer. As such, we are focused on driving an increased number of customers on our platform to support our long-term growth. Through our pay-as-you-go offering, a customer can subscribe to one of our many plans and begin using our platform within minutes, with minimal technical skill and no professional services. This has allowed us to acquire a large portion of paying customers very rapidly and at significantly lower customer acquisition costs. Additionally, we continue to invest to build our direct sales force and improve the sophistication of our sales operations. •Expansion of our existing customers. We believe that our platform enables a large opportunity for growth within our existing customer base given the breadth of products we offer on our platform. Our relationships with customers often start with servicing a portion of their overall network needs and expand over time as they realize the significant value we deliver. Once a customer has adopted one product on our platform it can easily add additional products with a single click. As we add more products and functionality to our platform, we see opportunities to drive upsell as customers seek to consolidate onto one platform to meet all of their security, performance, and reliability network requirements. •International reach. Our global network, with a presence in more than 200 cities in over 100 countries, has helped to foster our strong international growth. International markets represented 48% and 49% of our revenue in the three months endedSeptember 30, 2020 and 2019, respectively, and we intend to continue to invest in our international growth as a strategy to expand our customer base around the world. Initial Public Offering InSeptember 2019 , we completed an Initial Public Offering (IPO) in which we issued and sold 40,250,000 shares of Class A common stock, which included 5,250,000 shares sold pursuant to the exercise by the underwriters of an option to purchase additional shares, at the public offering price of$15.00 per share. We received net proceeds of$565.0 million from sales of our shares in the IPO, after deducting underwriting discounts and commissions and offering costs. Upon completion of the IPO, 31,381,152 shares of redeemable convertible preferred stock were automatically converted into an equal number of shares of Class A common stock, 134,276,690 shares of 39 -------------------------------------------------------------------------------- Table of contents redeemable convertible preferred stock were automatically converted into an equal number of shares of Class B common stock, outstanding warrants to purchase shares of redeemable convertible preferred stock were automatically converted into outstanding warrants to purchase shares of Class B common stock, and 15,198,587 shares of Class B common stock held by former employees were automatically converted into an equal number of shares of Class A common stock. Opportunities, Challenges, and Risks We believe that the growth of our business and our future success are dependent upon many factors, including growing our customer base, expanding our relationships with existing paying customers, developing and successfully launching new products, expanding into additional market segments, expanding our base of free customers, and developing and maintaining favorable peering and co-location relationships. Each of these factors presents significant opportunities for us, but also poses material challenges and risks that we must successfully address in order to grow our business and improve our operating results. We expect that addressing these challenges and risks will increase our operating expenses significantly over the next several years. The timing of our future profitability, if we achieve profitability at all, will depend upon many variables, including the success of our growth strategies and the timing and size of investments and expenditures that we choose to undertake, as well as market growth and other factors that are not within our control. In addition, we must comply with complex, uncertain, and evolving laws, rules, and regulatory requirements across federal, state, and international jurisdictions. If we fail to successfully address these challenges, risks, and variables, our business, operating results, financial condition, and prospects may be adversely affected.
COVID-19 Update
In earlyMarch 2020 , COVID-19, a disease caused by a novel strain of the coronavirus, was characterized as a pandemic by theWorld Health Organization . SinceDecember 2019 , COVID-19 has spread rapidly, with nearly all countries and territories worldwide having confirmed cases of COVID-19, and a high concentration of cases inthe United States and many other countries in which we and our customers, vendors, and partners operate. The rapid spread has resulted in authorities around the world periodically implementing and relaxing numerous measures to contain the virus, such as travel restrictions and bans, quarantines, shelter-in-place orders, and mandated business closures. The COVID-19 pandemic and these containment measures that have been in effect from time to time in various countries and territories have had, and are expected to continue to have, a substantial negative impact on businesses around the world and on global, regional, and national economies. We are closely monitoring the impact of the ongoing COVID-19 pandemic on all aspects of our business. While we believe the COVID-19 pandemic has had certain impacts on our business that we discuss in further detail below, we do not believe there has been, nor are we currently anticipating, a material adverse impact from the effects of the ongoing COVID-19 pandemic on our business and operations, results of operations, financial condition, and cash flows. However, the progression of the pandemic is uncertain, rapidly changing, and hard to predict. For example, after the initial spread of the pandemic during the spring, many countries began loosening containment measures in the summer, but the rapid escalation of infection rates inNorth America ,Europe , and other regions during the fall has led, and is expected to continue to lead, to an increase in containment measures in certain of those countries and territories. As a result, the broader implications of the COVID-19 pandemic on our business and operations and our financial results continue to be uncertain. The duration and severity of the economic downturn from the ongoing COVID-19 pandemic may negatively impact our business and operations, results of operations, financial condition, and cash flows. To date, the COVID-19 pandemic has impacted our employees, our network, and our customers in a number of ways, and this impact could worsen if and to the extent the pandemic continues or becomes more severe. •Our Employees. Our top priority during the COVID-19 pandemic is protecting the health and safety of our employees around the world. As the COVID-19 pandemic expanded globally during the spring, we activated our business continuity plan and transitioned our employees to a fully remote working environment in nearly all of our locations around the world and restricted almost all business travel. More recently, we have reopened, to a limited extent, most of our offices so that those of our employeeswho have difficult or challenging remote work circumstances are able to work from one of our offices located in jurisdictions that permit returns to offices and where we believe such a return to office can occur safely. Throughout the pandemic, our goal has been to ensure that our employees feel safe and secure, while having the flexibility and resources necessary to perform their jobs effectively. These efforts have included providing additional 40 -------------------------------------------------------------------------------- Table of contents equipment to employees for working remotely and providing various benefits to promote our employees' physical and mental well-being. We believe our employees have been able to remain productive during the COVID-19 pandemic and that our operations have not been materially impacted by our employees primarily working on a remote basis, but the continuation of the pandemic will place strains on our employees. As the progression of the pandemic continues, we will continue to monitor and follow guidance from authorities and health officials in the locations where we operate and modify our working environments around the world appropriately. To the extent current or future measures we implement result in decreased productivity, harm our company culture, or otherwise negatively affect our business, our financial condition, and operating results could be materially and adversely affected. We are continuing our efforts to increase our workforce to support the ongoing growth in our business, which currently is occurring through a virtual hiring and onboarding process. To date, we have not experienced difficulties in continuing to expand our workforce, but depending on the length and severity of the COVID-19 pandemic and its effect on our business, we may determine to slow our hiring. Any delays in expanding our workforce may result in key positions remaining unfilled, which could negatively impact our business, financial condition, or operating results. •Our Network. The change in everyday behavior caused by the COVID-19 pandemic during the nine months endedSeptember 30, 2020 has resulted in an increased reliance on the Internet, increased Internet traffic, and a geographic migration of Internet traffic from office-focused areas (like city centers and business parks) to more residential areas (like suburbs and outlying towns). We believe that traffic on the Internet, and on our network that we use to provide our products to our customers around the world, will remain elevated while the isolation mandates across the globe remain in place or where significantly greater numbers of workers continue to work remotely than was the case prior to the pandemic. Nevertheless, there is uncertainty about the impact on Internet traffic levels and work locations as the isolation mandates are periodically lifted and as more workers begin to return to working in office environments instead of remotely. Our business is dependent on our network providing our customers with secure, performant, and reliable network services every minute of every day. The pandemic has resulted not only in greatly increased traffic and strain on our network, but also adverse impacts on our ability to provision our network co-location facilities, including delays in our ability to obtain servers and other hardware and to ship and install such hardware at our network facilities. While we have been able to lessen these adverse impacts to date through our planning processes and use of alternative vendors, our ability to continue to provision our existing network facilities and expand into new network facilities may become more difficult and more expensive the longer the COVID-19 pandemic continues to negatively impact the vendors for our network hardware, which in turn could adversely impact our business and operations and results of operations. •Our Customers. The COVID-19 pandemic and the measures taken by governments around the world to contain the spread of COVID-19 are materially and adversely impacting many of our current and potential customers, and this impact could negatively impact our business and operations, results of operations, financial condition, and cash flows. During the nine months endedSeptember 30, 2020 , we experienced an increase in the sales cycle for our products with many customers. While we believe this increase could be a result of a number of factors, it is possible that the pandemic has contributed to the increase. Since the pandemic began, we also initially experienced an increase in the proportion of our pipeline of prospective future customers that was lost, as well as an increase during the nine months endedSeptember 30, 2020 of new and existing customers requesting concessions in terms of payment amounts and/or timing and earlier or additional termination rights than was the case prior to the pandemic. Depending on the future progression of the pandemic, we also may experience future slowing in our collections of outstanding accounts receivables from some of our customers. We expect these trends and risks to continue while the COVID-19 pandemic persists and they could intensify as the pandemic continues and the financial condition of some of our current and potential customers deteriorates. While we have sought to ameliorate these negative sales impacts through focusing on additional upselling opportunities with existing customers, concentrating our sales efforts on industries that are more insulated from the impact of the ongoing COVID-19 pandemic, and shifting our marketing strategy to better identify sales opportunities in the current environment, there can be no assurance that these efforts will be successful. During this ongoing COVID-19 pandemic, IT organizations are working tirelessly to ensure their teams remain safe and productive, while facing greater network demands, a rapid acceleration in remote work, and a growing risk of cyber threats. In the face of these challenges, we believe our mission of helping to build a better Internet is more 41 -------------------------------------------------------------------------------- Table of contents important than ever and we have taken a number of steps to increase access to our products for thosewho need them: •InMarch 2020 , we announced that ourCloudflare for Teams products would be free untilSeptember 1, 2020 , to ensure our customers and prospective customers have the tools they need to support secure and efficient remote work. During that period, we also removed usage caps for existingCloudflare for Teams users and provided onboarding sessions so these groups could continue business in the pandemic environment. •InApril 2020 , we announced that we would provide a free package of services to state and local governments worldwide untilSeptember 1, 2020 , to ensure they have the tools needed to secure their web infrastructure and internal teams. •We also announced that we would offerCloudflare Workers for free through Project Galileo, which is our initiative through which we provide our products to at-risk public interest groups at no cost. For further discussion of the challenges and risks we confront related to the COVID-19 pandemic and otherwise, please refer to Part II, Item 1A "Risk Factors" of this Quarterly Report on Form 10-Q, including the risk factor titled "The effects of the ongoing COVID-19 pandemic have materially affected how we and our customers, vendors, and partners are operating our businesses, and the duration and extent to which this will negatively impact our future business and operations, results of operations, financial condition and cash flows remain uncertain." Non-GAAP Financial Measures and Key Business Metrics We review a number of financial and operating metrics, including the following non-GAAP financial measures and key metrics to evaluate our business, measure our performance, identify trends affecting our business, formulate business plans, and make strategic decisions. Three Months Ended Nine Months Ended September 30, September 30, 2020 2019 2020 2019 (dollars in thousands) Gross profit$ 87,157 $ 57,908 $ 233,143 $ 157,867 Gross margin 76 % 78 % 76 % 78 % Loss from operations$ (21,252) $ (41,086) $ (82,027) $ (78,004) Non-GAAP loss from operations$ (4,546) $ (18,144) $ (28,426) $ (52,898) Operating margin (19) % (56) % (27) % (38) % Non-GAAP operating margin (4) % (25) % (9) % (26) % Net cash provided by (used in) operating activities$ 1,973 $ (17,786) $ (8,316) $ (30,343) Net cash used in investing activities$ (205,153) $ (92,829) $ (514,694) $ (64,982) Net cash provided by financing activities$ 1,156 $ 570,216 $ 498,180 $ 572,265 Free cash flow$ (17,854) $ (33,638) $ (68,611) $ (72,656) Net cash provided by (used in) operating activities (as a percentage of revenue) 2 % (24) % (3) % (15) % Free cash flow margin (16) % (45) % (22) % (36) % Paying customers 100,968 80,986 100,968 80,986 Paying customers (>$100,000 Annualized Revenue) 736 451 736 451 Non-GAAP Financial Measures In addition to our results determined in accordance with generally accepted accounting principles inthe United States (U.S. GAAP), we believe the following non-GAAP measures are useful in evaluating our operating performance. We use the following non-GAAP financial information to evaluate our ongoing operations and for internal planning and forecasting purposes. We believe that non-GAAP financial information, when taken collectively, may be helpful to investors because it provides consistency and comparability with past financial 42 -------------------------------------------------------------------------------- Table of contents performance. However, non-GAAP financial information is presented for supplemental informational purposes only, has limitations as an analytical tool, and should not be considered in isolation or as a substitute for financial information presented in accordance withU.S. GAAP. In particular, free cash flow is not a substitute for cash provided by (used in) operating activities. Additionally, the utility of free cash flow as a measure of our liquidity is further limited as it does not represent the total increase or decrease in our cash balance for a given period. In addition, other companies, including companies in our industry, may calculate similarly-titled non-GAAP measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of our non-GAAP financial measures as tools for comparison. A reconciliation is provided below for each non-GAAP financial measure to the most directly comparable financial measure stated in accordance withU.S. GAAP. Investors are encouraged to review the relatedU.S. GAAP financial measures and the reconciliation of these non-GAAP financial measures to their most directly comparableU.S. GAAP financial measures, and not to rely on any single financial measure to evaluate our business. Non-GAAP Loss from Operations and Non-GAAP Operating Margin We define non-GAAP loss from operations and non-GAAP operating margin asU.S. GAAP loss from operations andU.S. GAAP operating margin, respectively, excluding stock-based compensation expense and its related employer payroll taxes, amortization of acquired intangible assets, and acquisition-related and other expenses. 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. We exclude employer payroll tax expenses related to stock-based compensation, which is a cash expense, from certain of our non-GAAP financial measures, because such expenses are dependent upon the price of our common stock and other factors that are beyond our control and do not correlate to the operation of our business. We exclude amortization of acquired intangible assets, which is a non-cash expense, related to business combinations from certain of our non-GAAP financial measures because such expenses are related to business combinations and have no direct correlation to the operation of our business. We exclude acquisition-related and other expenses from certain of our non-GAAP financial measures because such expenses are related to business combinations and have no direct correlation to the operation of our business. Acquisition-related and other expenses can be cash or non-cash expenses incurred in connection with the acquisition, and include third-party transaction costs and compensation expense for key acquired personnel. Three Months Ended Nine Months Ended September 30, September 30, 2020 2019 2020 2019 (dollars in thousands) Loss from operations$ (21,252) $ (41,086) $ (82,027) $ (78,004) Add: Stock-based compensation expense and related employer payroll taxes 16,006 22,911 45,191 25,012 Amortization of acquired intangible assets 700 31 2,131 94 Acquisition-related and other expenses - - 6,279 - Non-GAAP loss from operations$ (4,546) $ (18,144) $ (28,426) $ (52,898) Operating margin (19) % (56) % (27) % (38) % Non-GAAP operating margin (non-GAAP loss from operations as a percentage of revenue) (4) % (25) % (9) % (26) % Free Cash Flow and Free Cash Flow Margin Free cash flow is a non-GAAP financial measure that we calculate as net cash provided by (used in) operating activities less cash used for purchases of property and equipment and capitalized internal-use software. Free cash flow margin is calculated as free cash flow divided by revenue. We believe that free cash flow and free cash flow margin are useful indicators of liquidity that provide information to management and investors about the amount of cash generated from our operations that, after the investments in property and equipment and capitalized internal-use software, can be used for strategic initiatives, including investing in our business, and strengthening our financial position. We believe that historical and future trends in free cash flow and free cash flow margin, even if negative, provide useful information about the amount of cash generated (or consumed) by our operating activities 43 -------------------------------------------------------------------------------- Table of contents that is available (or not available) to be used for strategic initiatives. For example, if free cash flow is negative, we may need to access cash reserves or other sources of capital to invest in strategic initiatives. One limitation of free cash flow and free cash flow margin is that they do not reflect our future contractual commitments. Additionally, free cash flow does not represent the total increase or decrease in our cash balance for a given period.

There are a number of limitations associated with the use of key business metrics as analytical tools, however, and we do not rely upon any single key business metric to evaluate our business. In addition, other companies, including companies in our industry, may calculate similarly-titled business metrics differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of these business metrics as tools for comparison to such companies. Beginning with the quarter endedMarch 31, 2020 , we have transitioned the method for calculating our key business metrics from a billings-based methodology to a revenue-based methodology. We believe the change in methodology to GAAP-based metrics provides improved disclosures for our investors by better aligning our key business metrics with GAAP and our financial statements and will provide a better representation of these important components of our operating model and business performance as we continue to grow our business. Paying Customers We believe our ability to grow the number of paying customers on our platform provides a key indicator of growth of our business and our future business opportunities. We define a paying customer as a person or entitywho has generated revenue during the quarter, excluding (i) customers that were not acquired through ordinary sales channels, (ii) customers using only our registrar product, and (iii) customers using our consumer applications, such as 1.1.1.1 and Warp, which agreements and customers together represent an insignificant amount of our revenue. An entity is defined as a company, a government institution, a non-profit organization, or a distinct business unit of a large company that has an active contract with us or one of our partners. The number of paying customers was 100,968 and 80,986 as ofSeptember 30, 2020 andSeptember 30, 2019 , respectively. Paying Customers (>$100,000 Annualized Revenue) While we continue to grow customers across all sizes, over time, our large customers have contributed an increasing share of our revenue. We view the number of customers with Annualized Revenue greater than 44 -------------------------------------------------------------------------------- Table of contents$100,000 as indicative of our penetration within large enterprise accounts. To measure Annualized Revenue, we take the sum of revenue for each customer in the quarter and multiply that amount by four. For example, if we signed a new customer that generated$600 of revenue in the quarter, that customer would account for$2,400 of Annualized Revenue for that year. Our Annualized Revenue calculation excludes (i) agreements that were not entered into through our ordinary sales channels, (ii) revenue generated from customers using only our registrar product, and (iii) customers using our consumer applications, such as 1.1.1.1 and Warp, which agreements and customers together represent an insignificant amount of our revenue. Our Annualized Revenue metric also includes any usage charges by a customer during a period, which represents a small portion of our total revenue and may not be recurring. As a result, Annualized Revenue may be higher than actual revenue over the course of the year. The number of paying customers with Annualized Revenue greater than$100,000 was 736 and 451 as ofSeptember 30, 2020 andSeptember 30, 2019 , respectively. We believe this trend will continue as customers increasingly adopt cloud technology and we are able to compete with an increasing share of our customers' legacy hardware solutions by adding new capabilities to our global cloud platform. Dollar-Based Net Retention Rate Our ability to maintain long-term revenue growth and achieve profitability is dependent on our ability to retain and grow revenue generated from our existing paying customers. We believe that we will achieve these objectives by continuing to focus on customer loyalty and adding additional products and functionality to our platform. Our dollar-based net retention rate is a key way we measure our performance in these areas. Dollar-based net retention measures our ability to retain and expand recurring revenue from existing customers. To calculate dollar-based net retention for a period, we compare the Annualized Revenue from paying customers four quarters prior to the Annualized Revenue from the same set of customers in the most recent quarter. Our dollar-based net retention includes expansion and is net of contraction and attrition, but excludes Annualized Revenue from new customers in the current period. Our dollar-based net retention excludes the benefit of free customers that upgrade to a paid subscription between the prior and current periods, even though this is an important source of incremental growth. We believe this provides a more meaningful representation of our ability to add incremental business from existing paying customers as they renew and expand their contracts. Our dollar-based net retention rates for the three months endedSeptember 30, 2020 andSeptember 30, 2019 were 116% and 121%, respectively. Components of Our Results of Operations
Revenue
We generate revenue primarily from sales to our customers of subscriptions to access our platform, together with related support services. Arrangements with customers generally do not provide the customer with the right to take possession at any time of our software operating our global cloud platform. Instead, customers are granted continuous access to our platform and products over the contractual period. A time-elapsed output method is used to measure progress because we transfer control evenly over the contractual period. Accordingly, the fixed consideration related to subscription and support revenue is generally recognized on a straight-line basis over the contract term beginning on the date that the service is made available to the customer. Usage-based consideration is primarily related to fees charged for our customer's use of excess bandwidth when accessing our platform in a given period and is recognized as revenue in the period in which the usage occurs. The typical subscription and support term for our contracted customers is one year and subscription and support term lengths range from one to three years. Most of our contracts with contracted customers are non-cancelable over the contractual term. Customers typically have the right to terminate their contracts for cause if we fail to perform in accordance with the contractual terms. For our pay-as-you-go customers, subscription and support terms are typically monthly. Cost of Revenue Cost of revenue consists primarily of expenses that are directly related to providing our service to our paying customers. These expenses include expenses related to operating in co-location facilities, network and bandwidth costs, depreciation of our equipment located in co-location facilities, certificate authority services costs for paying customers, related overhead costs, the amortization of our capitalized internal-use software, and the amortization of acquired developed technologies. Cost of revenue also includes employee-related costs, including salaries, bonuses, benefits, and stock-based compensation for employees whose primary responsibilities relate to supporting 45 -------------------------------------------------------------------------------- Table of contents our paying customers. Other costs included in cost of revenue include credit card fees related to processing customer transactions and allocated overhead costs. As our customers expand and increase the use of our global cloud platform driven by additional applications and connected devices, we expect that our cost of revenue will increase due to higher network and bandwidth costs and expenses related to operating in additional co-location facilities. However, we expect to continue to benefit from economies of scale as our customers increase the use of our global cloud platform. We intend to continue to invest additional resources in our global cloud platform and our customer support organizations as we grow our business. The level and timing of investment in these areas could affect our cost of revenue in the future. Gross Profit and Gross Margin Gross profit is revenue less cost of revenue and gross margin is gross profit as a percentage of revenue. Our gross profit and gross margin have and are expected to continue to fluctuate from period to period due to the timing of acquisition of new customers and our renewals with existing customers, expenses related to operating in co-location facilities and network and bandwidth costs to operate and expand our global cloud platform, and amortization of costs associated with capitalized internal-use software. We expect our gross profit to increase in absolute dollars and our gross margin to remain consistent over the long term, although our gross margin could fluctuate from period to period depending on the interplay of all of these factors. Operating Expenses Sales and Marketing Sales and marketing expenses consist primarily of employee-related costs, including salaries, benefits, and stock-based compensation expense, sales commissions that are recognized as expenses over the period of benefit, marketing programs, certificate authority services costs for free customers, travel-related expenses, bandwidth and co-location costs for free customers, and allocated overhead costs. Sales commissions earned by our sales force and the associated payroll taxes that are direct and incremental to the acquisition of channel partner and direct customer contracts are deferred and amortized over an estimated period of benefit of three years for the initial acquisition of a contract and over the contractual term of the renewals for renewal contracts. We plan to continue to invest in sales and marketing to grow our customer base and increase our brand awareness, including marketing efforts to continue to drive our pay-as-you-go business model. As a result, we expect our sales and marketing expenses to increase in absolute dollars for the foreseeable future. However, we expect our sales and marketing expenses to decrease as a percentage of our revenue over the long term, although our sales and marketing expenses may fluctuate as a percentage of our revenue from period to period due to the timing and extent of these expenses. Research and Development Research and development costs consist primarily of employee-related costs, including salaries, benefits, and stock-based compensation expense, consulting costs, depreciation of equipment used in research and development, and allocated overhead costs. Research and development costs support our efforts to add new features to our existing offerings and to ensure the security, performance, and reliability of our global cloud platform. We expect our research and development expenses to increase in absolute dollars for the foreseeable future as we continue to invest in research and development efforts to enhance the functionality of our global cloud platform. However, we expect our research and development expenses to decrease as a percentage of our revenue over the long term, although our research and development expenses may fluctuate as a percentage of our revenue from period to period due to the timing and extent of these expenses. General and Administrative General and administrative expenses consist primarily of employee-related costs, including salaries, benefits, and stock-based compensation expense for our finance, legal, human resources, and other administrative personnel, professional fees for external legal services, accounting, and other consulting services, bad debt expense, and allocated overhead costs. We expect our general and administrative expenses to continue to increase in absolute dollars for the foreseeable future to support our growth as well as due to additional costs associated with legal, accounting, compliance, insurance, investor relations, and other costs as a result of operating as a public company. 46 -------------------------------------------------------------------------------- Table of contents However, we expect our general and administrative expenses to decrease as a percentage of our revenue over the long term, although our general and administrative expenses may fluctuate as a percentage of our revenue from period to period due to the timing and extent of these expenses. Non-Operating Income (Expense) Interest Income Interest income consists primarily of interest earned on our cash, cash equivalents, and our investment holdings. Interest Expense Interest expense consists primarily of contractual interest expense and amortization of the discount and debt issuance costs on our$575.0 million aggregate principal amount of 0.75% Convertible Senior Notes dueMay 2025 (the Notes) which were issued inMay 2020 . Previously, interest expense consisted primarily of interest related to our built-to-suit lease financing obligation and interest on our notes payable. Other Income (Expense), Net Other income (expense), net consists primarily of gain on sale of property and equipment and foreign currency transaction gains and losses. The three and nine months endedSeptember 30, 2019 also included expenses resulting from the revaluation of our redeemable convertible preferred stock warrant liability and its conversion upon the IPO. Provision for (Benefit from) Income Taxes Provision for (benefit from) income taxes consists primarily of income taxes in certain foreign jurisdictions in which we conduct business, as well as state income taxes inthe United States . We maintain a full valuation allowance on our federal and state deferred tax assets as we have concluded that it is more likely than not that the deferred tax assets will not be realized. 47

The change was primarily driven by excess tax benefits from stock-based compensation deductions in theUnited Kingdom , offset by withholding taxes in theU.S. and income tax expense from profitable foreign jurisdictions. The provision for income taxes decreased by$6.3 million for the nine months endedSeptember 30, 2020 compared to the nine months endedSeptember 30, 2019 . The change was primarily driven by the partial release of theU.S. valuation allowance in connection with the acquisition of S2 and excess tax benefits from stock-based compensation deductions in theUnited Kingdom , offset by withholding taxes in theU.S. and income tax expense from profitable foreign jurisdictions. Liquidity and Capital Resources Since our inception, we have financed our operations primarily through net proceeds from the sale of our equity and debt securities, as well as payments received from customers using our global cloud platform. InSeptember 2019 , we completed our IPO in which we issued and sold 40,250,000 shares of Class A common stock at a price per share to the public of$15.00 . We received net proceeds of$565.0 million from sales of our shares in the IPO, net of underwriters' discounts and commissions, after deducting offering costs of$5.5 million . InMay 2020 , we issued$575.0 million aggregate principal amount of 0.75% Convertible Senior Notes dueMay 2025 (the Notes) in a private offering to qualified institutional buyers pursuant to Rule 144A promulgated under the Securities Act, from which we received total net proceeds, after deducting initial purchaser discounts and debt issuance costs, of$562.5 million . As ofSeptember 30, 2020 , we had cash and cash equivalents of$112.0 million , including$5.6 million held by our foreign subsidiaries. We do not expect to incur material taxes in the event we repatriate any of these amounts. Our cash and cash equivalents primarily consist of cash, highly liquid money market funds, and commercial paper. We also had available-for-sale securities of$939.3 million consisting ofU.S. treasury securities,U.S. government agency securities, commercial paper, and corporate bonds. As ofSeptember 30, 2020 , the Company's investment portfolio consisted of highly-rated investment grade securities with an average credit rating of AA+. We have generated significant operating losses from our operations as reflected in our accumulated deficit of$386.5 million as ofSeptember 30, 2020 and negative cash flows from operations. We expect to continue to incur operating losses and generate negative cash flows from operations for the foreseeable future due to the investments we intend to make in our business, and as a result we may require additional capital resources to execute on our strategic initiatives to grow our business. We believe that our existing cash, cash equivalents, and available-for-sale securities will be sufficient to meet our working capital and capital expenditure needs for at least the next 12 months. Our assessment of the period of time through which our financial resources will be adequate to support our operations is a forward-looking statement and involves risks and uncertainties. Our actual results could vary as a result of, and our near- and long-term future capital requirements will depend on, many factors, including our growth rate, subscription renewal activity, the timing and extent of spending to support our infrastructure and research and development efforts, the expansion of sales and marketing activities, the timing of new introductions of products or features, and the continuing market adoption of our global cloud platform, and the impact of the ongoing COVID-19 pandemic to our and our customers', vendors', and partners' businesses. We may in the future enter into arrangements to acquire or invest in complementary businesses, services and technologies, including intellectual property rights. We have based our estimates on assumptions that may prove to be wrong, and we could use our available capital resources sooner than we currently expect. Additionally, some of the factors that may influence our operations are not within our control, such as general economic conditions and the length and severity of the COVID-19 pandemic. We may be required to seek additional equity or debt financing. In the event that additional financing is required from outside 53 -------------------------------------------------------------------------------- Table of contents sources, we may not be able to raise it on terms acceptable to us or at all. If we are unable to raise additional capital when desired, or if we cannot expand our operations or otherwise capitalize on our business opportunities because we lack sufficient capital, our business, operating results, and financial condition would be adversely affected.

Off-Balance Sheet Arrangements As ofSeptember 30, 2020 , we did not have any relationships with unconsolidated organizations or financial partnerships, such as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. Critical Accounting Policies, Significant Judgments and Use of Estimates Our condensed consolidated financial statements are prepared in accordance withU.S. GAAP. The preparation of these condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and related disclosures. Our estimates are based on historical experience and various other assumptions that we believe to be reasonable under the circumstances, and we evaluate our estimates and assumptions on an ongoing basis. Due to the ongoing COVID-19 pandemic, there is ongoing uncertainty and significant disruption in the global economy and financial markets. We are not aware of any specific event or circumstance that would require an update to our estimates or assumptions or a revision of the carrying value of assets or liabilities as ofNovember 10, 2020 , the date of issuance of this Quarterly Report on Form 10-Q. These estimates and assumptions may change in the future, however, as new events occur and additional information is obtained. Our actual results could differ from these estimates. Our significant accounting policies are discussed in Note 2 to our consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year endedDecember 31, 2019 . There have been no significant changes to these policies for the nine months endedSeptember 30, 2020 , except as described in Note 2 to our condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q. JOBS Act Accounting Election We meet the definition of an emerging growth company under the JOBS Act, which permits us to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies. We have elected to use this extended transition period until we are no longer an emerging growth company or until we affirmatively and irrevocably opt out of the extended transition period. As a result, our condensed consolidated financial statements may not be comparable to companies that comply with new or revised accounting pronouncements applicable to public companies. Based on our aggregate worldwide market value of voting and non-voting common equity held by non-affiliates as ofJune 30, 2020 , we expect that we will become a "large accelerated filer" and lose emerging growth status beginning with our Annual Report on Form 10-K for the year endedDecember 31, 2020 . Recently Issued Accounting Pronouncements
