SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, which statements involve substantial risks and uncertainties. Forward-looking statements generally relate to future events or our future financial or operating performance. In some cases, you can identify forward-looking statements because they contain words such as “may,” “will,” “should,” “expects,” “plans,” “anticipates,” “could,” “intends,” “target,” “projects,” “contemplates,” “believes,” “estimates,” “predicts,” “potential,” or “continue,” or the negative of these words, or other similar terms or expressions that concern our expectations, strategy, plans, or intentions.

Forward-looking statements contained in this Quarterly Report on Form 10-Q include, but are not limited to, statements about:

•the impact of the ongoing COVID-19 pandemic, including on our and our customers’, vendors’, and partners’ respective businesses and the markets in which we and our customers, vendors, and partners operate;

•our ability to retain and upgrade paying customers;

•our ability to attract new paying customers, including large customers, or convert free customers to paying customers;

•our future financial performance, including trends in revenue, costs of revenue, gross profit or gross margin, operating expenses, paying customers, and free cash flow;

•our ability to achieve or maintain profitability;

•the consequences we may face resulting from the activities of our customers and the actions we take in response, including associated theories of liability;

•the demand for our products or for solutions for security, performance, and reliability in general;

•possible harm caused by significant disruption of service, loss or unauthorized access to customers’ content, or the actual or perceived failure of our products to prevent security incidents;

•our ability to compete successfully in competitive markets;

•our ability to respond to rapid technological changes;

•our ability to continue to innovate and develop new products;

•our expectations and management of future growth;

•our ability to maintain existing co-location relationships, ISP partnerships, and other interconnection arrangements around the world;

•our ability to offer high-quality customer support;

•our ability to manage our global operations;

•our expectations of and ability to comply with applicable laws around the world;

•our ability to correctly estimate our tax obligations around the world;

•our ability to service the interest on our convertible senior notes and repay such notes, to the extent required;

•our ability to attract and retain key personnel and other highly qualified personnel;

•our ability to maintain our brand;

•our ability to prevent serious errors or defects across, and to otherwise maintain the uninterrupted operation of, our network;

•our ability to maintain, protect, and enhance our intellectual property; and

•our ability to successfully identify, acquire, and integrate companies and assets.

You should not rely upon forward-looking statements as predictions of future events. We have based the forward-looking statements contained in this Quarterly Report on Form 10-Q primarily on our current expectations and

Table of contents

projections about future events and trends that we believe may affect our business, financial condition, results of operations, and prospects. The outcome of the events described in these forward-looking statements is subject to risks, uncertainties, and other factors described in the section titled “Risk Factors” and elsewhere in this Quarterly Report on Form 10-Q. Readers are urged to carefully review and consider the various disclosures made in this Quarterly Report on Form 10-Q and in other documents we file from time to time with the Securities and Exchange Commission (SEC) that disclose risks and uncertainties that may affect our business. Moreover, we operate in a very competitive and rapidly changing environment. New risks and uncertainties emerge from time to time, and it is not possible for us to predict all risks and uncertainties that could have an impact on the forward-looking statements contained in this Quarterly Report on Form 10-Q. We cannot assure you that the results, events, and circumstances reflected in the forward-looking statements will be achieved or occur, and actual results, events, or circumstances could differ materially from those described in the forward-looking statements.

The forward-looking statements made in this Quarterly Report on Form 10-Q relate only to events as of the date on which the statements are made. We undertake no obligation to update any forward-looking statements made in this Quarterly Report on Form 10-Q to reflect events or circumstances after the date of this Quarterly Report on Form 10-Q or to reflect new information or the occurrence of unanticipated events, except as required by law. We may not actually achieve the plans, intentions, or expectations disclosed in our forward-looking statements, and you should not place undue reliance on our forward-looking statements. Our forward-looking statements do not reflect the potential impact of any future acquisitions, mergers, dispositions, joint ventures, or investments we may make.

In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon information available to us as of the date of this Quarterly Report on Form 10-Q, and while we believe such information forms a reasonable basis for such statements, such information may be limited or incomplete, and our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information. These statements are inherently uncertain and investors are cautioned not to unduly rely upon these statements.

SELECTED RISKS AFFECTING OUR BUSINESS

Investing in our Class A common stock involves numerous risks, including those set forth below. This summary does not contain all of the information that may be important to you, and you should read this risk factor summary together with the more detailed discussion of risks and uncertainties set forth in Part II, Item 1A. Risk Factors of this Quarterly Report on Form 10-Q. Below are summaries of some of these risks, any one of which could materially adversely affect our business, financial condition, results of operations, and prospects.

•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.

•We have a history of net losses and may not be able to achieve or sustain profitability in the future.

•We have experienced rapid revenue growth, which may not be indicative of our future performance.

•If we are unable to attract new paying and free customers, our future results of operations could be harmed.

•Our business depends on our ability to retain and upgrade paying customers and, to a lesser extent, convert free customers to paying customers, and any decline in renewals, upgrades, or conversions could adversely affect our future results of operations.

•If we are unable to attract, expand, and retain sales to large customers, or we fail to mitigate the additional risks associated with serving such customers, our business, results of operation, and financial condition may suffer.

•Activities of our paying and free customers or the content of their websites or other Internet properties, as well as our response to those activities, could cause us to experience significant adverse political, business, and reputational consequences with customers, employees, suppliers, government entities, and others.

•We face intense and increasing competition, which could adversely affect our business, financial condition, and results of operations.

•If we do not effectively expand, train, and retain our sales force, we may be unable to add new contracted customers, or increase sales to our existing customers and our business would be adversely affected.

Table of contents

•We rely on our key technical, sales, and management personnel to grow our business, and the loss of one or more key employees or the inability to attract and retain qualified personnel could harm our business.

•Our relatively limited operating history makes it difficult to evaluate our current business and prospects and may increase the risk that we will not be successful.

•Problems with our internal systems, networks, or data, including actual or perceived breaches or failures, could cause our network or products to be perceived as insecure, underperforming, or unreliable, our reputation to be damaged, and our financial results to be negatively impacted.

•If our global network that delivers our products or the core co-location facilities we use to operate our network are damaged or otherwise fail to meet the requirement of our business or local regulations, our ability to provide access to our network and products to our customers and maintain the performance of our network could be negatively impacted, which could cause our business, results of operations and financial condition to suffer.

•Detrimental changes in, or the termination of, any of our co-location relationships, ISP partnerships, or our other interconnection relationships with ISPs could adversely impact our business, results of operations, and financial condition.

•The actual or perceived failure of our products to block malware or prevent a security breach could harm our reputation and adversely impact our business, results of operations, and financial condition.

•Activities of our paying and free customers or the content of their websites and other Internet properties may violate applicable laws and/or our terms of service and could subject us to lawsuits, regulatory enforcement actions, and/or liability in various jurisdictions.

•Our actual or perceived failure to comply with privacy, data protection, and information security laws, regulations, and obligations could harm our business.

•Our network presence within China is dependent upon our commercial relationship with JD Cloud & AI, and any detrimental changes in, or the termination of, that relationship could jeopardize our ability to offer an integrated global network that includes China.

•The dual class structure of our common stock has the effect of concentrating voting control with those stockholders who held our capital stock prior to the completion of our initial public offering, and it may depress the trading price of our Class A common stock.

•Servicing our future debt, including our convertible senior notes, may require a significant amount of cash, and we may not have sufficient cash flow from our business to pay our indebtedness.

CLOUDFLARE, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

Note 1. Organization and Basis of Presentation

Organization and Description of Business

Cloudflare, Inc. (the Company, Cloudflare, we, us, or our) is a global cloud services provider that delivers a broad range of 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. Cloudflare’s network serves as a scalable, easy-to-use, unified control plane to deliver security, performance, and reliability across on-premise, hybrid, cloud, and software-as-a-service (SaaS) applications. The Company was incorporated in Delaware in July 2009. The Company is headquartered in San Francisco, California.

Basis of Presentation and Principles of Consolidation

The accompanying interim condensed consolidated financial statements and accompanying notes have been prepared in conformity with generally accepted accounting principles in the United States (U.S. GAAP) and applicable regulations of the Securities and Exchange Commission (the SEC) regarding interim financial reporting, and include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. The Company’s fiscal year ends on December 31.

Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to the applicable required disclosures and regulations of the SEC. Therefore, these unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the related notes thereto included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2020.

Initial Public Offering

In September 2019, the Company completed an initial public offering (IPO) in which it issued and sold Class A common stock for net proceeds of $565.0 million, after deducting underwriting discounts and commissions and offering costs. Upon completion of the IPO, all of the Company's outstanding redeemable convertible preferred stock was automatically converted into Class A common stock and Class B common stock. In addition, all of the outstanding warrants to purchase shares of the Company's redeemable convertible preferred stock were automatically converted into outstanding warrants to purchase shares of Class B common stock, and all of the shares of Class B common stock held by former employees were automatically converted into Class A common stock.

Unaudited Interim Condensed Consolidated Financial Information

The accompanying interim condensed consolidated balance sheet as of ~~June~~September 30, 2021, the condensed consolidated statements of operations and of comprehensive loss for the three and ~~six~~nine months ended ~~June~~September 30, 2021 and 2020, the condensed consolidated statements of cash flows for the ~~six~~nine months ended ~~June~~September 30, 2021 and 2020, the condensed consolidated statements of stockholders’ equity for the three and ~~six~~nine months ended ~~June~~September 30, 2021 and 2020, and the related footnote disclosures are unaudited. These unaudited interim condensed consolidated financial statements have been prepared in accordance with U.S. GAAP. In management’s opinion, the unaudited interim condensed consolidated financial statements include all adjustments necessary to state fairly the Company’s financial position as of ~~June~~September 30, 2021, its results of operations for the three and ~~six~~nine months ended ~~June~~September 30, 2021 and 2020, and its cash flows for the ~~six~~nine months ended ~~June~~September 30, 2021 and 2020. The results for the three and ~~six~~nine months ended ~~June~~September 30, 2021 are not necessarily indicative of the results expected for the full year ending December 31, 2021 or any future period. The unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the related notes thereto included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2020.

Use of Estimates

Table of contents

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed in the condensed consolidated financial statements and accompanying notes to the condensed consolidated financial statements. Such estimates include, but are not limited to, allowance for doubtful accounts, deferred contract acquisitions costs, the period of benefit generated from the Company’s deferred contract acquisition costs, the capitalization and estimated useful life of internal-use software, the assessment of recoverability of intangible assets and their estimated useful lives, useful lives of property and equipment, liability and equity allocation of convertible senior notes, the determination of the incremental borrowing rate used for operating lease liabilities, the valuation and recognition of stock-based compensation expense, uncertain tax positions, and the recognition and measurement of current and deferred income tax assets and liabilities. Management bases these estimates and assumptions on historical experience and on various other assumptions that are believed to be reasonable. Due to the COVID-19 pandemic, there is ongoing uncertainty and significant disruption in the global economy and financial markets. The Company is not aware of any specific event or circumstance that would require an update to its estimates or assumptions or a revision of the carrying value of its assets or liabilities as of ~~August 6,~~November 5, 2021, 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~~. obtained. Actual results could differ materially from these estimates.

Note 2. Summary of Significant Accounting Policies

Significant Accounting Policies

The Company's significant accounting policies are discussed in the "Notes to Consolidated Financial Statements, Note 2. Summary of Significant Accounting Policies" in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2020. There have been no significant changes to these policies that have had a material impact on the Company's condensed consolidated financial statements and related notes, ~~since~~except as noted below.

Convertible Senior Notes

The Company accounts for its 0.75% Convertible Senior Notes due 2025 (the 2025 Notes) and its 0.00% Convertible Senior Notes due 2026 (the 2026 Notes and together with the ~~filing~~2025 Notes, the Notes) as separate liability and equity components. The carrying amount of the ~~Company's Annual Report on Form 10-K~~liability component was calculated by measuring the fair value of a similar debt instrument that does not have an associated convertible feature. The carrying amount of the equity component, representing the conversion option, was calculated by deducting the fair value of the liability component from the total principal of the Notes. The excess of the principal amount of the liability component over its book value (debt discount) is amortized to interest expense over the term of the Notes. In accounting for the ~~year ended December 31, 2020.~~issuance costs related to the Notes, the allocation of issuance costs incurred between the liability and equity components was based on their relative values. Issuance costs attributable to the liability component are being amortized over the contractual term of the Notes.

Transactions involving contemporaneous exchanges of cash between the same debtor and creditor in connection with the issuance of a new debt obligation and satisfaction of an existing debt obligation by the debtor should be evaluated for an exchange transaction if the exchange is determined to have substantially different terms. For exchange transactions that are considered an extinguishment of debt, the total consideration for such an exchange is separated into liability and equity components by estimating the fair value of a similar liability without a conversion option and assigning the residual value to the equity component. The gain or loss on extinguishment of the debt is subsequently determined by comparing repurchase consideration allocated to the liability component to the sum of the carrying value of the liability component, net of the proportionate amounts of unamortized debt discount and remaining unamortized debt issuance costs.

Recent Accounting Pronouncements

Recently Issued Accounting Pronouncements

In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (ASC 470-20) and Derivatives and Hedging - Contracts in Entity's Own Equity (ASC 815-40). The FASB issued this ASU to simplify the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity's own equity. The Company does not have any contracts on its own equity; however, the Company does have convertible debt. This ASU removes the separation models for 1) convertible debt with a cash conversion feature and 2) convertible instruments with a beneficial conversion feature, as well as enhances the related disclosure and earnings per share guidance. Additionally, this update requires that convertible

Table of contents

debt be recognized as a single liability measured at its amortized cost, if no bifurcation is required, and as a result, interest expense will be closer to the coupon interest rate. For public business entities, these amendments are effective for fiscal years beginning after December 15, 2021, with early adoption permitted for fiscal years beginning after December 15, 2020. The Company is currently evaluating the impact of this accounting standard update on its consolidated financial statements.

Reclassification of prior year presentation

Certain prior year amounts have been reclassified for consistency with the current year presentation. Specifically, Accrued compensation is now presented as a separate line item on the condensed consolidated balance sheets and was previously included within Accrued expense and other current liabilities.

Note 4. Fair Value Measurements

Fair value is defined as the exchange price that would be received from sale of an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

Assets and liabilities measured at fair value are classified into the following categories:

•Level I: Observable inputs are unadjusted quoted prices in active markets for identical assets or liabilities;

•Level II: Observable inputs are quoted prices for similar assets and liabilities in active markets or inputs other than quoted prices that are observable for the assets or liabilities, either directly or indirectly through market corroboration, for substantially the full term of the financial instruments; and

•Level III: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. These inputs are based on the Company’s own assumptions used to measure assets and liabilities at fair value and require significant management judgment or estimation.

The Company's cash equivalents are comprised of highly liquid money market funds and commercial paper. The Company classifies money market funds within Level I of the fair value hierarchy because they are valued based on quoted market prices in active markets. The Company classifies its investments, which are comprised of U.S. treasury securities, U.S. government agency securities, commercial paper, and corporate bonds, within Level II of the fair value hierarchy because the fair value of these securities is priced by using inputs based on non-binding market consensus prices that are primarily corroborated by observable market data or quoted market prices for similar instruments. The Company recognizes transfers between levels within the fair value hierarchy, if any, at the end of each period. There were no transfers between levels during the periods presented.

The following table summarizes the Company’s cash and available-for-sale securities’ amortized cost, unrealized gains (losses), and fair value by significant investment category reported as cash and cash equivalents, restricted ~~cash, or available-for-sale securities as of June 30, 2021 and December 31, 2020.~~

The Company classifies financial instruments in Level III of the fair value hierarchy when there is reliance on at least one significant unobservable input to the valuation model. In addition to these unobservable inputs, the valuation models for Level III financial instruments typically also rely on a number of inputs that are readily observable, either directly or indirectly. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires management to make judgments and consider factors specific to the asset or liability. There were no financial instruments classified as Level III of the fair value hierarchy as of ~~June~~September 30, 2021 and December 31, 2020.

Note 6. Leases

The Company's lease ~~portfoli~~oportfolio consists of real estate and co-location agreements in the U.S. and internationally. The real estate leases include leases for office space and have remaining lease terms of up to ~~3.4~~9.8 years. Certain of these leases contain options that allow the Company to extend or terminate the lease agreement. The Company's co-location leases have remaining lease terms of up to ~~6.8~~6.6 years. All of the Company's leases are classified as operating leases.

On July 6, 2021, the Company entered a triple net lease (the "Austin Lease") for 128,195 square feet of office space in Austin, Texas. The Lease has an accounting lease term of 121 months plus 2 options to renew for five years each at 100% market rate. At lease commencement, it was not reasonably certain that these renewal options will be exercised. The total fixed payments per the terms of the Austin Lease are approximately $$46.2 million plus the Company's share of operating costs for the maturity of the lease.

During the three months ended September 30, 2021, the reasonably certain holding period for two foreign real estate leases was modified as the Company became reasonably certain that the renewal options for these agreements would be exercised. The reasonably certain holding period for both leases increased by their respective renewal term lengths, which amounted to an additional undiscounted cash payment of $26.8 million based on the terms of their existing agreements.

The Company also subleased one of its leased office spaces. The lease term of the sublease ended during the three months ended June 30, 2021. Sublease income, which is recorded as a reduction of rent expense was ~~$0.4~~zero and $1.1 million andfor the three and nine months ended September 30, 2021, respectively, and $0.7 million and $2.1 million for the three months ~~ended June 30, 2021~~ and ~~2020, respectively and $1.1 million and $1.4 million for the six~~nine months ended ~~June~~September 30, ~~2021 and~~ 2020, respectively.

As of ~~June~~September 30, 2021, the Company had ~~$33.4~~$28.8 million of total undiscounted future payments under operating leases that have not yet commenced, which were not included on the condensed consolidated balance sheets. These operating leases will commence between ~~July~~ October 2021 and October 2024 and have an average lease term of ~~3.5~~4.1 years.

As of ~~June~~September 30, 2021,, the weighted-average remaining term of the Company’s operating leases was ~~2.9~~ 6.2 years and the weighted-average discount rate used to measure the present value of the operating lease liabilities was ~~3.2%~~3.5%.

Convertible Senior Notes

2026 Convertible Senior Notes

In ~~May 2020,~~August 2021, the Company issued ~~$575.0~~$1,293.8 million aggregate principal amount of the 2026 Notes in a private offering to qualified institutional buyers pursuant to Rule 144A promulgated under the Securities Act, including thethe initial ~~purchasers'~~purchasers’ exercise in full of their option to purchase an additional ~~$75.0~~$168.8 million aggregate principal ~~amount~~amounts of the 2026 Notes. The total net proceeds from the issuance of the 2026 Notes, after deducting initial purchaser discounts and debt issuance costs, were ~~$562.5 million~~.$1,274.0 million.

The 2026 Notes are senior unsecured obligations of the Company and will mature on ~~May~~August 15, ~~2025,~~2026, unless earlier redeemed, repurchased, or converted, and are governed by the terms of the ~~Indenture~~indenture dated ~~May 15, 2020~~August 13, 2021 (the 2026 Indenture). ~~Interest is payable semi-annually in arrears on May 15~~The 2026 Notes are 0% convertible senior notes and ~~November 15 of each year, beginning on November 15, 2020, at a rate of 0.75% per year.~~therefore do not bear regular cash interest.

The 2026 Notes are convertible at an initial conversion rate of ~~26.7187~~5.2263 shares of the Company's Class A common stock per $1,000 principal amount of the 2026 Notes, which is equivalent to an initial conversion price of approximately ~~$37.43~~$191.34 per share, subject to adjustment upon the occurrence of specified ~~events.~~events in accordance with the terms of the 2026 Indenture. The 2026 Notes may be converted at any time on or after ~~February~~May 15, ~~2025~~2026 until the close of business on the second scheduled trading day immediately preceding the maturity date. Holders of the 2026 Notes may convert all or any portion of their 2026 Notes at their option at any time prior to the close of business on the business day immediately preceding ~~February~~May 15, ~~2025~~2026 only under the following circumstances:

(1) during any calendar quarter commencing after the calendar quarter ending on ~~September 30, 2020~~December 31, 2021 (and only during such calendar quarter), if the last reported sale price of the Company's Class A common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day;

(2) during the 5 business day period after any 5 consecutive trading day period in which the trading price per $1,000 principal amount of the 2026 Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Company's Class A common stock and the conversion rate on each such trading day;

(3) if the Company calls such 2026 Notes for redemption, at any time prior to the close of business on the second scheduled trading day immediately preceding the redemption date; or

(4) upon the occurrence of specified corporate events.

The circumstances described in paragraph (1) above were met during the second quarter of 2021 and as a result, the Notes are convertible at the option of the holder from July 1, 2021 until September 30, 2021.

~~Table of contents~~

In addition, if the 2026 Notes are converted prior to the maturity date following certain specified corporate events or because the Company issues a notice of redemption, the Company will increase the conversion rate for such 2026 Notes converted in connection with such a corporate event or during the related redemption period, as the case may be, in certain ~~circumstances.~~circumstances set forth in the 2026 Indenture.

Table of contents

Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of the Company's Class A common stock, or a combination of cash and shares of the Company's Class A common stock, at the Company's election. It is the Company’s current intent to settle the principal amount of 2026 Notes ~~with~~in cash.

The Company may not redeem the 2026 Notes prior to August 20, 2024. The Company may redeem for cash all or any portion of the 2026 Notes (subject to the partial redemption limitation (as defined below)), at its option, on or after August 20, 2024, if the last reported sale price of the Company’s Class A common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day preceding the date on which the Company provides notice of redemption at a redemption price equal to 100% of the principal amount of the 2026 Notes to be redeemed, plus any accrued and unpaid special interest to, but excluding, the redemption date. If the Company elects to redeem fewer than all of the outstanding 2026 Notes, at least $100.0 million aggregate principal amount of 2026 Notes must be outstanding and not subject to redemption as of the relevant redemption date. No sinking fund is provided for the 2026 Notes.

If the Company undergoes a fundamental change (as defined in the 2026 Indenture), holders of the 2026 Notes may require the Company to repurchase for cash all or any portion of their notes at a repurchase price equal to 100% of the principal amount of the 2026 Notes to be repurchased, plus accrued and unpaid special interest to, but excluding, the fundamental change repurchase date.

In accounting for the issuance of the 2026 Notes, the Company separated the 2026 Notes into liability and equity components. The initial carrying amount of the liability component of approximately $1,027.6 million, net of costs incurred, was calculated by using an effective interest rate of 4.65%, which was determined by measuring the fair value of similar debt instruments that did not have an associated convertible feature. The carrying amount of the equity component representing the conversion option and recorded in additional paid-in capital was $266.2 million and was determined by deducting the fair value of the liability component from the par value of the 2026 Notes. The equity component is not remeasured as long as it continues to meet the conditions for equity classification. The excess of the principal amount of the liability component over its carrying amount represents a debt discount that is amortized to interest expense over the contractual term of the 2026 Notes.

In accounting for the issuance costs related to the 2026 Notes, the Company allocated the total amount incurred to the liability and equity components based on the proportion of the proceeds allocated to the debt and equity components. Issuance costs attributable to the liability component were $15.7 million (presented as a reduction to the carrying amount of debt) and are being amortized to interest expense over the contractual term of the 2026 Notes. The issuance costs attributable to the equity component were $4.1 million and are netted against the equity component in additional paid-in capital.

The net carrying amount of the liability component of the 2026 Notes was as follows:


	September 30, 2021
	(in thousands)
Principal	$	1,293,750
Unamortized debt discount	(260,150)
Unamortized debt issuance costs	(15,327)
Carrying amount of the liability component, net	$	1,018,273

The net carrying amount of the equity component of the 2026 Notes was as follows:


	September 30, 2021
	(in thousands)
Proceeds allocated to the conversion option (debt discount)	$	266,150
Less: allocated issuance costs	(4,073)
Carrying amount of the equity component, net	$	262,077

Based on the closing price of the Company's Class A common stock of $112.65 on September 30, 2021, the if-converted value of the 2026 Notes does not exceed its principal amount. The remaining life of the 2026 Notes was approximately 59 months as of September 30, 2021.

The following table sets forth total interest expense recognized related to the 2026 Notes:

2026 Capped Call Transactions

In connection with the offering of the 2026 Notes, the Company entered into privately-negotiated capped call transactions (the 2026 Capped Calls) with certain financial institution counterparties. The 2026 Capped Calls each have an initial strike price of approximately $191.34 per share of the Company's Class A common stock, subject to certain adjustments, which corresponds to the initial conversion price of the 2026 Notes. The 2026 Capped Calls each have an initial cap price of approximately $250.94 per share, subject to certain adjustments. The 2026 Capped Calls initially cover, subject to anti-dilution adjustments, approximately 6.8 million shares of the Company's Class A common stock. The 2026 Capped Calls are intended to generally offset potential dilution to the Company's Class A common stock upon conversion of the 2026 Notes and/or offset the potential cash payments that the Company could be required to make in excess of the principal amount upon any conversion, subject to the cap price. The 2026 Capped Calls are subject to either adjustment or termination upon the occurrence of certain specified events affecting the Company, including a merger event, a tender offer, and a nationalization, insolvency, or delisting involving the Company. The 2026 Capped Calls expire in incremental components on each trading date between July 17, 2026 and August 13, 2026.

The 2026 Capped Calls are recorded in stockholders' equity and are not accounted for as derivatives. The premium paid for the purchase of the 2026 Capped Calls of $86.3 million was recorded as a reduction to additional paid-in capital on the condensed consolidated balance sheets.

2025 Convertible Senior Notes

In May 2020, the Company issued $575.0 million aggregate principal amount of the 2025 Notes in a private offering to qualified institutional buyers pursuant to Rule 144A promulgated under the Securities Act, including the initial purchasers' exercise in full of their option to purchase an additional $75.0 million aggregate principal amount of the 2025 Notes. The total net proceeds from the issuance of the 2025 Notes, after deducting initial purchaser discounts and debt issuance costs, were $562.5 million. Immediately following the closings of the 2025 Notes Exchange (defined below), $175.0 million in aggregate principal amount of the 2025 Notes remained outstanding as of September 30, 2021.

The 2025 Notes are senior unsecured obligations of the Company and will mature on May 15, 2025, unless earlier redeemed, repurchased, or converted, and are governed by the terms of the Indenture dated May 15, 2020 (the 2025 Indenture and, together with the 2026 Indenture, the Indentures). Interest on the 2025 Notes is payable semi-annually in arrears on May 15 and November 15 of each year, beginning on November 15, 2020, at a rate of 0.75% per year.

The 2025 Notes are convertible at an initial conversion rate of 26.7187 shares of the Company's Class A common stock per $1,000 principal amount of the 2025 Notes, which is equivalent to an initial conversion price of approximately $37.43 per share, subject to adjustment upon the occurrence of specified events in accordance with the terms of the 2025 Indenture. The 2025 Notes may be converted at any time on or after February 15, 2025 until the close of business on the second scheduled trading day immediately preceding the maturity date. Holders of the 2025 Notes may convert all or any portion of their 2025 Notes at their option at any time prior to the close of business on the business day immediately preceding February 15, 2025 only under the following circumstances:

(1) during any calendar quarter (and only during such calendar quarter), if the last reported sale price of the Company's Class A common stock for at least 20 trading days (whether or not consecutive) during a period

of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day;

(2) during the 5 business day period after any 5 consecutive trading day period in which the trading price per $1,000 principal amount of the 2025 Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Company's Class A common stock and the conversion rate on each such trading day;

(3) if the Company calls such 2025 Notes for redemption, at any time prior to the close of business on the second scheduled trading day immediately preceding the redemption date; or

(4) upon the occurrence of specified corporate events.

The circumstances described in paragraph (1) above were met during the third quarter of 2021 and as a result, the 2025 Notes are convertible at the option of the holder from October 1, 2021 until December 31, 2021. As of September 30, 2021, no holders had converted the 2025 Notes.

In addition, if the 2025 Notes are converted prior to the maturity date following certain specified corporate events or because the Company issues a notice of redemption, the Company will increase the conversion rate for such 2025 Notes converted in connection with such a corporate event or during the related redemption period, as the case may be, in certain circumstances set forth in the 2025 Indenture.

The Company may not redeem the 2025 Notes prior to May 20, 2023. The Company may redeem for cash all or any portion of the 2025 Notes, at its option, on or after May 20, 2023, if the last reported sale price of the Company’s Class A common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day preceding the date on which the Company provides notice of redemption at a redemption price equal to 100% of the principal amount of the 2025 Notes to be redeemed, plus any accrued and unpaid interest to, but excluding, the redemption date. No sinking fund is provided for the 2025 Notes.

If the Company undergoes a fundamental change (as defined in the 2025 Indenture), holders of the 2025 Notes may require the Company to repurchase for cash all or any portion of their notes at a ~~fundamental change~~ repurchase price equal to 100% of the principal amount of the 2025 Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date.

In accounting for the issuance of the 2025 Notes, the Company separated the 2025 Notes into liability and equity components. The carrying amount of the liability component was calculated by using an effective interest rate of 10.0%, which was determined by measuring the fair value of similar debt instruments that did not have an associated convertible feature. The carrying amount of the equity component representing the conversion option and recorded in additional paid-in capital was $205.3 million and was determined by deducting the fair value of the liability component from the par value of the 2025 Notes. The equity component is not remeasured as long as it continues to meet the conditions for equity classification. The excess of the principal amount of the liability component over its carrying amount represents a debt discount that is amortized to interest expense over the contractual term of the 2025 Notes.

In accounting for the issuance costs related to the 2025 Notes, the Company allocated the total amount incurred to the liability and equity components based on the proportion of the proceeds allocated to the debt and equity components. Issuance costs attributable to the liability component were $8.0 million (presented as a reduction to the carrying amount of debt) and are being amortized to interest expense over the contractual term of the 2025 Notes. The issuance costs attributable to the equity component were $4.5 million and are netted against the equity component in additional paid-in capital.

2025 Notes Exchange

On August 13, 2021, the Company closed privately-negotiated exchange agreements with certain holders of the 2025 Notes to exchange approximately $400.0 million in aggregate principal amount of the 2025 Notes (the 2025 Notes Exchange) for an aggregate of $400.7 million in cash (including accrued interest) and approximately 7.6 million shares of the Company’s Class A common stock (the Exchange Shares) for aggregate consideration of $1,321.0 million. The Company used a portion of the net proceeds from the offering of the 2026 Notes to fund the 2025 Notes Exchange. As a result, the Company recorded a debt extinguishment loss of $72.2 million, representing the difference between the fair value of the liability component of $355.3 million and the carrying value of the 2025 Notes Exchange of $283.1 million at the closing date. The fair value of the liability component was calculated by using an effective interest rate of 4.08%, which was determined by measuring the fair value of similar debt instruments that did not have an associated convertible feature and adjusted to reflect the term of the remaining 2025 Notes. The aggregate consideration of $1,321.0 million was allocated between the fair value of the liability component of $355.3 million and the reacquisition of the equity component of $965.7 million, which was recorded as a reduction to additional paid-in capital and offset by the additional paid-in capital for the Exchange Shares issued.

The net carrying amount of the liability component of the 2025 Notes was as follows:

Based on the closing price of the Company's Class A common stock of ~~$105.84~~$112.65 on ~~June~~September 30, 2021, the if-converted value of the 2025 Notes exceeded its principal amount by approximately ~~$1,051.0~~$351.7 million.

2025 Capped Call Transactions

In connection with the offering of the 2025 Notes, the Company entered into privately-negotiated capped call transactions (the 2025 Capped Calls and, together with the 2026 Capped Calls, the capped call transactions)with certain financial institution counterparties ~~(the Capped Calls)~~. The 2025 Capped Calls each have an initial strike price of approximately $37.43 per share of the Company's Class A common stock, subject to certain adjustments, which corresponds to

Table of contents

the initial conversion price of the 2025 Notes. The 2025 Capped Calls each have an initial cap price of ~~approximately~~ $57.58 per share, subject to certain adjustments. The 2025 Capped Calls initially cover, subject to anti-dilution adjustments, approximately 15.4 million shares of the Company's Class A common stock. The 2025 Capped Calls are intended to generally offset potential dilution to the Company's Class A common stock upon conversion of the 2025 Notes and/or offset the potential cash payments that the Company could be required to make in excess of the principal amount upon any conversion, subject to the cap price. The 2025 Capped Calls are subject to either adjustment or termination upon the occurrence of certain specified events affecting the Company, including a merger event, a tender offer, and a nationalization, insolvency, or delisting involving the Company. The 2025 Capped Calls expire in incremental components on each trading date between March 18, 2025 and May 13, 2025. As of September 30, 2021, the terms of the 2025 Capped Calls have not been adjusted and no 2025 Capped Calls were exercised in connection with the 2025 Notes Exchange.

The 2025 Capped Calls are recorded in stockholders' equity and are not accounted for as derivatives. The premium paid for the purchase of the 2025 Capped Calls of $67.3 million was recorded as a reduction to additional paid-in capital on the condensed consolidated balance sheets.

Note 8. Commitments and Contingencies

Purchase Commitments

Open purchase commitments are for the purchase of services under non-cancelable contracts. They are not recorded as liabilities on the condensed consolidated balance sheet as of ~~June~~September 30, 2021 as the Company has not yet received the related services. Refer to the table below for purchase commitments under non-cancelable contracts with various vendors as of ~~June~~September 30, 2021.

Legal Matters

From time to time the Company is a party to various legal proceedings that arise in the ordinary course of business. In addition, third parties may from time to time assert claims against the Company in the form of letters and other communications. Management currently believes that there is no pending or threatened legal proceeding to which the Company is a party that is likely to have a material adverse effect on the Company’s condensed consolidated financial statements. However, the results of legal proceedings are inherently unpredictable and if an unfavorable ruling were to occur in any of the legal proceedings there exists the possibility of a material adverse effect on the Company’s financial position, results of operations, and cash flows. The Company accrues for legal proceedings that it considers probable and for which the loss can be reasonably estimated. The Company also discloses material contingencies when it believes a loss is not probable but reasonably possible. Legal costs incurred and expected to be incurred related to litigation matters are expensed as incurred.

The Company’s network and associated products are subject to various restrictions under U.S. export control and sanctions laws and regulations, including the U.S. Department of Commerce’s Export Administration Regulations (EAR) and various economic and trade sanctions regulations administered by the U.S. Department of the Treasury’s Office of Foreign Assets Controls (OFAC). The U.S. export control laws and U.S. economic sanctions laws include restrictions or prohibitions on the sale or supply of certain products and services to U.S. embargoed or sanctioned countries, governments, persons and entities and also require authorization for the export of certain encryption items. In addition, various countries regulate the import of certain encryption technology, including through import permitting and licensing requirements and have enacted or could enact laws that could limit the Company’s ability to distribute its network.

Although the Company takes precautions to prevent its network and associated products from being accessed or used in violation of such laws, the Company may have inadvertently allowed its network and associated products to be accessed or used by some customers in apparent violation of U.S. economic sanctions laws, including by users in embargoed or sanctioned countries, and the Company may have exported or allowed the download of certain software prior to making required filings with the U.S. Department of Commerce’s Bureau of Industry and Security. As a result, the Company has submitted to OFAC and to the Bureau of Industry and Security a voluntary self-disclosure concerning potential violations, and the Company has submitted a voluntary self-disclosure to the Census Bureau regarding potential violations of the Foreign Trade Regulations related to some incorrect electronic export information statements to the U.S. government for certain hardware exports, which were authorized. The voluntary self-disclosure to the Census Bureau was completed with no penalties in November 2019, and the voluntary self-disclosure to the Bureau of Industry and Security was completed with no penalties in June 2020. The voluntary self-disclosure to OFAC remains under review. If the Company is found to be in violation of U.S. economic sanctions or export control laws, it could result in substantial fines and penalties for the Company and for the individuals working for the Company. The Company may also be adversely affected through other penalties,

~~Table of contents~~

reputational harm, loss of access to certain markets or otherwise. No loss has been recognized in the condensed consolidated financial statements for this loss contingency as it is not probable a loss has been incurred and the range of a possible loss is not yet estimable.

Guarantees and Indemnifications

If the Company's services do not meet certain service level commitments, its contracted customers and certain of its pay-as-you-go customers are entitled to receive service credits, and in certain cases, refunds, each representing a form of variable consideration. To date, the Company has not incurred any material costs as a result of such commitments.

The Company’s arrangements generally include certain provisions for indemnifying customers against liabilities if its products or services infringe a third-party’s intellectual property rights. It is not possible to determine the maximum potential amount under these indemnification obligations due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. To date, the Company has not incurred any material costs as a result of such obligations and has not accrued any liabilities related to such obligations in the condensed consolidated financial statements.

The Company has also agreed to indemnify its directors, executive officers, and certain other employees for costs associated with any fees, expenses, judgments, fines, and settlement amounts incurred by them in any action or proceeding to which any of them are, or are threatened to be, made a party by reason of their service as a director or officer. The Company maintains director and officer insurance coverage that would generally enable it to recover

a portion of any future amounts paid. The Company also may be subject to indemnification obligations by law with respect to the actions of its employees under certain circumstances and in certain jurisdictions.

Note 9. Common Stock

The Company’s amended and restated certificate of incorporation authorizes the issuance of Class A common stock and Class B common stock. The holder of each share of Class A common stock is entitled to 1 vote per share, while the holder of each share of Class B common stock is entitled to 10 votes per share. As of ~~June~~September 30, 2021 and December 31, 2020, the Company was authorized to issue 2,250,000,000 shares of Class A common stock and 315,000,000 shares of Class B common stock, each with a par value of $0.001 per share. There were ~~263,095,826~~273,574,792 and 249,401,232 shares of Class A common stock issued and outstanding as of ~~June~~September 30, 2021 and December 31, 2020, respectively. The number of shares of Class B common stock issued and outstanding was ~~49,269,288~~48,038,501 and 59,238,742, as of ~~June~~September 30, 2021 and December 31, 2020, respectively.

Holders of the Company’s Class A common stock and Class B common stock are entitled to dividends when, as and if, declared by the Company’s Board of Directors, subject to the rights of the holders of all classes of stock outstanding having priority rights to dividends. Any dividends paid to the holders of the Class A common stock and Class B common stock will be paid on a pro rata basis. As of ~~June~~September 30, 2021 and December 31, 2020, the Company had not declared any dividends. The rights of the holders of Class A and Class B common stock are identical, except with respect to voting and conversion. Shares of the Company's Class B common stock are convertible into an equivalent number of shares of the Company's Class A common stock and generally convert into shares of the Company's Class A common stock upon cessation of employment or transfer, except for certain transfers described in the Company's amended and restated certificate of incorporation. Class A common stock and Class B common stock are referred to, collectively, as common stock throughout the notes to these condensed consolidated financial statements, unless otherwise indicated.

Note 10. Stock-based Compensation

Equity Incentive Plans

In 2010, the Company's Board of Directors adopted and stockholders approved the 2010 Equity Incentive Plan (2010 Plan). The 2010 Plan is a broad-based retention program and is intended to attract and retain talented employees, directors, and non-employee consultants. The 2010 Plan provides for the granting of stock options, restricted stock, RSUs, and stock appreciation rights to employees, directors, and consultants. Incentive stock options may be granted only to employees. All other awards under the 2010 Plan, including non-qualified stock options, may be granted to employees, directors, and consultants. Except for qualifying assumptions and substitutions of options, the exercise price of an incentive stock option and non-qualified stock option shall not be less than 100% of the fair market value of such shares on the date of grant. Prior to the Company's IPO, stock-based awards forfeited, canceled, or repurchased generally were returned to the pool of shares of common stock available for issuance under the 2010 Plan. In connection with the IPO, the 2010 Plan was terminated effective immediately prior to the effectiveness of the 2019 Equity Incentive Plan (2019 Plan) and the Company ceased granting any additional awards under the 2010 Plan. All outstanding awards under the 2010 Plan at the time of the

Table of contents

termination of the 2010 Plan remain subject to the terms of the 2010 Plan, and any shares underlying stock options that expire or terminate or are forfeited or repurchased by the Company under the 2010 Plan will be automatically transferred to the 2019 Plan.

In 2019, the Company's Board of Directors adopted and stockholders approved the 2019 Plan, which became effective one business day prior to the effective date of the Company's registration statement on Form S-1 for the IPO. The 2019 Plan provides for the granting of stock options, restricted stock, RSUs, stock appreciation rights, performance shares, performance stock units, and performance awards for the Company's Class A common stock to the Company's employees, directors, and consultants. Except as otherwise indicated below, the maximum number of shares of Class A common stock that may be issued under the 2019 Plan will not exceed 66,661,953 shares of the Company's Class A common stock, which is the sum of (1) 29,335,000 new shares, plus (2) an additional number of shares of Class A common stock not to exceed 37,326,953, consisting of the total number of shares of Class A or Class B common stock subject to outstanding awards granted under the 2010 Plan that, on or after the 2019 Plan became effective, are canceled, expire, or otherwise terminate prior to exercise or settlement; are repurchased by the Company because of the failure to vest; or are forfeited, tendered to, or withheld by the Company (or not issued) to satisfy a tax withholding obligation or the payment of an exercise price, if any, as such shares become available from time to time. Stock-based awards under the 2019 Plan that expire or are forfeited, canceled, or repurchased generally are returned to the pool of shares of Class A common stock available for issuance under the 2019 Plan. In addition, the number of shares of the Company's Class A common stock reserved for issuance under the 2019 Plan will automatically increase on January 1 of each calendar year, starting on January 1, 2021 through January 1, 2029, in an amount equal to the least of (i) 29,335,000 shares, (ii) 5% of the total number of shares of Class A and Class B common stock outstanding on December 31 of the fiscal year before the date of each automatic increase, or (iii) a lesser number of shares determined by the compensation committee of the Company's Board of Directors prior to the applicable January 1.

Stock Options

~~Table of contents~~

Under the 2010 Plan and 2019 Plan, at exercise, stock option awards entitle the holder to receive ~~one~~1 share of Class B or Class A common stock, in the case of the 2010 Plan, or ~~one~~1 share of Class A common stock, in the case of the 2019 Plan. Stock options granted under the 2010 Plan and the 2019 Plan generally vest over a four-year period subject to remaining continuously employed and expire no more than 10 years from the date of grant. The following table summarizes the stock options activity under the 2010 Plan and 2019 Plan for the ~~six~~nine months ended ~~June~~September 30, 2021:

The Company did not grant any stock options during the three and ~~six~~nine months ended ~~June~~September 30, 2021. The weighted-average assumptions used to determine the fair value of stock options granted during the ~~six~~nine months ended ~~June~~September 30, 2020 were as follows:

Table of contents


	~~Six~~Nine months ended ~~June~~September 30,
		2020
Expected term (in years)		6.0
Expected volatility		40.3	%
Risk-free interest rate		0.7	%
Dividend yield		0—

The weighted-average grant date fair value of options granted during the ~~six~~nine months ended ~~June~~September 30, 2020 was ~~$9.32~~$9.74 per share.

The aggregate intrinsic value is the difference between the exercise price of the option and the estimated fair value of the underlying common stock. Options exercisable include ~~8,328,418~~7,259,920 and 10,765,894 options that were unvested as of ~~June~~September 30, 2021 and December 31, 2020, respectively.

The total grant date fair value for vested options in the ~~six~~nine months ended ~~June~~September 30, 2021 and 2020 was ~~$8.7~~$11.4 million and ~~$3.7~~$5.5 million, respectively.

As of ~~June~~September 30, 2021 and December 31, 2020, there was ~~$15.8~~$13.7 million and $20.6 million, respectively, of unrecognized stock-based compensation expense related to unvested stock options that is expected to be recognized over a weighted-average period of ~~2.3~~2.1 years and 2.6 years, respectively.

The 2010 Plan allows for the early exercise of stock options for certain individuals as determined by the Company’s Board of Directors. Shares of common stock issued upon early exercises of unvested options are not deemed, for accounting purposes, to be issued until those shares vest according to their respective vesting schedules and accordingly, the consideration received for early exercises is initially recorded as a liability and reclassified to common stock and additional paid-in capital as the underlying awards vest. Stock options that are early exercised

~~Table of contents~~

are subject to a repurchase option that allows the Company to repurchase within six months of an individual’s termination for any reason, including death and disability (or in the case of shares issued upon exercise of an option after termination, within six months of the date of exercise), any unvested shares of such individual for a repurchase price equal to the amount previously paid by the individual for such unvested shares. As of ~~June~~September 30, 2021 and December 31, 2020, the Company had ~~$6.5~~$5.5 million and $8.6 million, respectively, recorded in liability for early exercise of unvested stock options, and the related number of unvested shares subject to repurchase was ~~2,932,886~~2,505,209 and 3,871,772, respectively.

Restricted Stock and Restricted Stock Units

RSUs granted under the 2010 Plan generally vest upon the satisfaction of both a service-based vesting condition and a performance vesting condition, as defined below, occurring before these RSUs expire. RSUs granted under the 2019 Plan generally vest upon the satisfaction of a service-based vesting condition. The service-based vesting condition for employees under both the 2010 Plan and the 2019 Plan is typically satisfied over a four-year period, subject to remaining continuously employed. The performance vesting condition under the 2010 Plan was deemed satisfied upon the effective date of the Company's registration statement on Form S-1 filed with the SEC in connection with the IPO.

In connection with the acquisition of S2 Systems Corporation (S2), the Company issued 948,000 shares of Class A common stock to former S2 shareholders, some of which have joined the Company as employees. Of these issued shares, 841,000 shares are restricted stock that is subject to vesting, with 77.8% of this restricted stock vesting in two years from the acquisition date and the remainder of this restricted stock vesting in three years from the acquisition date, in each case subject to remaining continuously employed. ~~NaN~~None of these restricted shares vested during the three and ~~six~~nine months ended ~~June~~September 30, 2021. The total grant date fair value for vested shares in the ~~six~~nine months ended ~~June~~September 30, 2020 was $1.8 million.

The total stock-based compensation expense for shares of unvested restricted stock for the ~~six~~nine months ended ~~June~~September 30, 2021 and 2020 was ~~$2.8~~$4.2 million and ~~$2.8~~$4.2 million, respectively. As of ~~June~~September 30, 2021 and 2020,

2019 Employee Stock Purchase Plan

In September 2019, the Company's Board of Directors adopted and stockholders approved the 2019 Employee Stock Purchase Plan (ESPP), which became effective one business day prior to the effective date of the Company's registration statement on Form S-1 filed with the SEC in connection with the IPO. A total of 5,870,000 shares of Class A common stock were initially reserved for sale under the ESPP. The number of shares of Class A common stock reserved for issuance includes an annual increase on the first day of each fiscal year, beginning on January 1, 2021, by the least of (1) 5,870,000 shares of Class A common stock, (2) 1% of the total number of shares of Class A and Class B common stock outstanding on December 31 of the fiscal year before the date of each automatic increase; or (3) such lesser amount as the compensation committee of the Company's Board of Directors may determine prior to the applicable January 1.

Generally, all regular employees, including executive officers, employed by the Company or by any of its designated subsidiaries, except for those holding 5% or more of the total combined voting power or value of all classes of common stock, may participate in the ESPP and may contribute, normally through payroll deductions, up to 10% of their eligible compensation for the purchase of Class A common stock under the ESPP. Unless otherwise determined by the compensation committee of the Board of Directors, Class A common stock will be purchased for the accounts of employees participating in the ESPP at a price per share that is the lesser of (1) 85% of the fair market value of a share of the Company's Class A common stock on the first date of an offering period, or (2) 85% of the fair market value of a share of the Company's Class A common stock on the date of purchase.

The ESPP generally provides for six-month offering periods beginning on the first day of trading on or after November 15 and May 15 of each year and terminating on the last trading day on or before May 15 and November 15, approximately six months later, with identical purchase periods. Current employees cannot sell the shares of Class A common stock purchased under the ESPP until the day after the one-year anniversary of the purchase date of such shares, except for the withholding or sale of shares by the Company to meet any applicable tax withholding obligations. No employee may purchase (i) during each purchase period more than 1,500 shares of Class A common stock and (ii) shares under the ESPP at a rate in excess of $25,000 worth of the Company's Class A

common stock based on the fair market value per share of the Company's Class A common stock at the beginning of an offering for each calendar year such purchase right is outstanding.

During the three and ~~six~~nine months ended ~~June~~September 30, 2021, respectively, zero and ~~June~~130,870 shares of Class A common stock were purchased under the ESPP. During the three and nine months ended September 30, 2020, respectively, ~~130,870~~zero and 421,300 shares of Class A common stock were purchased under the ESPP. As of ~~June~~September 30, 2021 and December 31, 2020, the total unrecognized stock-based compensation expense related to the ESPP was ~~$2.5~~$0.9 million and $2.0 million, respectively, that is expected to be recognized over a weighted average period of ~~0.4~~0.1 years.

Note 12. Income Taxes

The computation of the provision for (benefit from) income taxes for interim periods is determined by applying the estimated annual effective tax rate to year-to-date earnings from recurring operations and adjusting for discrete tax items recorded in the period. The Company's ability to estimate the geographic mix of earnings is impacted by the relatively high-growth nature of the business, fluctuations of business operations by country, and implementation of tax planning strategies.

The Company recorded an income tax benefit of ~~$4.3~~$3.1 million and ~~$1.9~~$3.5 million for the three months ended ~~June~~September 30, 2021 and 2020, respectively, and ~~$5.1~~an income tax benefit $8.2 million and ~~$2.3~~$5.8 million for the ~~six~~nine months ended ~~June~~September 30, 2021 and 2020, respectively.

The benefit from income taxes of ~~$4.3~~$3.1 million for the three months ended ~~June~~September 30, 2021 was primarily related to the excess tax benefits from stock-based compensation deductions in the United Kingdom, offset by withholding

Table of contents

taxes in the U.S. and income tax expense from profitable foreign jurisdictions. The benefit from income taxes of $3.5 million for the three months ended September 30, 2020 was primarily related to excess tax benefits from stock-based compensation deductions in the United Kingdom, offset by withholding taxes in the U.S. and income tax expense from profitable foreign jurisdictions.

The benefit from income taxes of $8.2 million for the nine months ended September 30, 2021 was primarily related to the excess tax benefits from stock-based compensation deductions and the remeasurement of deferred tax assets from an enacted tax rate change in the United Kingdom, offset by withholding taxes in the U.S. and income tax expense from profitable foreign jurisdictions. The benefit from income taxes of ~~$1.9~~$5.8 million for the ~~three~~nine months ended June 30, 2020 was primarily related to excess tax benefits from stock-based compensation deductions in the United Kingdom, offset by withholding taxes in the U.S. and income tax expense from profitable foreign jurisdictions.

The benefit from income taxes of $5.1 million for the six months ended June 30, 2021 was primarily related to the excess tax benefits from stock-based compensation deductions and the remeasurement of deferred tax assets from an enacted tax rate change in the United Kingdom, offset by withholding taxes in the U.S. and income tax expense from profitable foreign jurisdictions. The benefit from income taxes of $2.3 million for the six months ended JuneSeptember 30, 2020 was primarily related to the partial release of the U.S. valuation allowance in connection with the acquisition of S2 and excess tax benefit from stock-based compensation deductions in the United Kingdom, offset by withholding taxes in the U.S. and income tax expense from profitable foreign jurisdictions.

In determining the need for a valuation allowance, the Company weighs both positive and negative evidence in the various jurisdictions in which it operates to determine whether it is more likely than not that its deferred tax assets are realizable. Accordingly, there is no valuation allowance in the foreign jurisdictions. A full valuation allowance has been established in the U.S. and no deferred tax assets and related tax benefits have been recognized in the consolidated financial statements.

Note 13. Business Combinations

In January 2020, the Company acquired all of the outstanding shares of S2, a company based in Kirkland, Washington that has developed browser isolation technology, for a total purchase consideration of $17.7 million. The Company is incorporating S2's technology into the Company's Cloudflare Gateway product. The total purchase consideration included (i) acquisition-date cash payments of $13.7 million, net of $0.1 million of cash acquired, (ii) $1.8 million in shares of the Company’s Class A common stock, and (iii) a cash holdback of $2.2 million, which the Company is retaining for up to 18 months and will be payable to the previous owners of S2, subject to offset by the Company for any of the previous owners’ indemnification obligations in connection with the acquisition. Such cash holdback was paid in full during the three months ended September 30, 2021. Concurrent

~~Table of contents~~

with the closing of the acquisition, the Company made a cash payment of $6.9 million to repay S2’s debt, which was part of the acquisition-date cash payments included in the purchase consideration.

In connection with the acquisition, the Company entered into compensation arrangements for stock-based and cash awards with a value totaling $20.3 million, of which $1.4 million and ~~$8.5~~$10.0 million were recognized as total compensation expense during the three and ~~six~~nine months ended ~~June~~September 30, 2020, respectively. The Company recorded an additional $1.4 million and ~~$2.8~~$4.2 million of compensation expense during the three and ~~six~~nine months ended ~~June~~September 30, 2021, respectively. The remaining compensation amount of ~~$6.1~~$4.7 million is being recognized over a future weighted-average period of ~~1.7~~1.5 years subject to the recipients’ continued service with the Company.

The fair values of assets acquired and liabilities assumed on the acquisition date are summarized as follows (in thousands):


Prepaid expenses and other current assets	$	6
Developed technology	5,600
Goodwill	13,084
Total assets acquired	18,690
Accrued expenses and other current liabilities	(208)
Other noncurrent liabilities	(782)
Total purchase price	$	17,700

A note payable of $0.2 million, included in accrued expenses and other current liabilities in the table above, assumed on the acquisition date, was paid off during the fiscal year ended December 31, 2020.

The acquired assets and assumed liabilities were recorded at their estimated fair values. The estimated useful life for the acquired developed technology is two years. The excess of the purchase price over the fair value of the net assets acquired was allocated to goodwill, none of which is expected to be deductible for tax purposes. Goodwill is primarily attributable to the assembled workforce as well as the anticipated synergies from the integration of S2's

technology with the Company's technology. A purchase accounting adjustment of $0.8 million to revise purchase consideration and goodwill was made during the fiscal year ended December 31, 2020.

This acquisition did not have a material impact on the Company’s condensed consolidated financial statements; therefore, historical and pro forma disclosures have not been presented.

Note 14. Segment and Geographic Information

The Company’s chief operating decision maker (CODM) is its CEO, President and COO, and CFO. Collectively, the CODM reviews financial information presented on a consolidated basis for purposes of allocating resources and evaluating financial performance. The Company has no segment managers who are held accountable by the CODM for operations, operating results, and planning for levels or components below the consolidated unit level. Accordingly, the Company has determined it has a single operating segment.

Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

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. In addition to historical financial information, the following 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. Our fiscal year end is December 31.

Overview

Cloudflare’s mission is to help build a better Internet. We have built a global network that delivers a broad range of 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 network serves as a scalable, easy-to-use, unified control plane to deliver security, performance, and reliability across their on-premise, hybrid, cloud, and software-as-a-service (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 network at low marginal cost.

We generate revenue primarily from sales to our customers of subscriptions to access our network and products. 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, we offer the ability to purchase our products through our website. We make our pay-as-you-go product solutions available in several configurations. For customers securing and accelerating their Internet properties, 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. For pay-as-you-go customers who need a scalable zero trust solution to secure users and internal resources, we make our Cloudflare for Team products available on a per seat basis. In addition, for developers building serverless applications, we offer our Cloudflare Workers to our pay-as-you-go customers on a usage-based plan that is metered by requests and execution time. Our implementation period for pay-as-you-go customers is extremely short with most customers implementing our services within a matter of minutes. Pay-as-you-go customers can subscribe to more than one solution and purchase add-on products and network 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, 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:

Table of contents

•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 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 network 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 products 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 a Cloudflare customer. As such, we are focused on driving an increased number of customers on our infrastructure 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 network 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 network enables a large opportunity for growth within our existing customer base given the breadth of products we offer on our infrastructure 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 network it can easily add additional products with a single click. As we add more products and functionality to our network, we see opportunities to drive upsell as customers seek to consolidate onto one infrastructure platform to meet all of their security, performance, and reliability network requirements.

◦International reach. Our global network, with a presence in more than ~~200~~250 cities and over 100 countries worldwide, has helped to foster our strong international growth. International markets represented ~~48%~~47% and ~~51%~~48% of our revenue in the three months ended ~~June~~September 30, 2021 and 2020, respectively, and we intend to continue to invest in our international growth as a strategy to expand our customer base around the world.

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

Table of contents

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

The rapid spread of the COVID-19 virus and ~~new~~ variants, such as the Delta variant, have 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 since early 2020 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. Although vaccines for COVID-19 have been developed and are being administered in the United States and other countries around the world, the expansion of administering these vaccines to additional people within these and other countries, and the long-term efficacy of these vaccines, and the receptivity of many people to receiving these vaccines remain uncertain.

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 administration of vaccines began in the first half of 2021 and ~~decreased~~ infection rates decreased in the summer, many countries began loosening containment measures, but the rapid spread of ~~new~~ variants, such as the highly transmissible Delta variant, and recent escalation of infection rates, as well as the ongoing discovery of numerous additional variants and mutations of the virus around the world, has led, and is expected to continue to lead, to an increase in containment measures in certain 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 of 2020, 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. Since that time, we have reopened, to a limited extent, most of our offices so that those of our employees who 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. In addition, subject to the availability and receipt of vaccinations by our employees and the existence of low infection rates in the various jurisdictions where we have offices, particularly in the face of the expanding prevalence of the Delta variant, we currently are planning for the reintroduction of our employees to some or all of our offices ~~later~~ in ~~2021.~~2022.

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 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

3841

Table of contents

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. ToDuring the pandemic, 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 be unsuccessful in continuing to increase our workforce sufficiently to support the ongoing growth of our business. Alternatively, 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 initial change in everyday behavior caused by the COVID-19 pandemic 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 if and for so long as the isolation mandates across the globe continue to remain in place or are reinstituted 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 lifted and as more workers 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~~slowdowns and shortages in the supply chains for many products that have adversely impacted 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~~and the related supply chain constraints continue 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 periodically taken by governments and businesses around the world to contain the spread of COVID-19 are materially and adversely impacting ~~many~~some of our current and potential customers, and this impact could negatively ~~impact~~affect our business and operations, results of operations, financial condition, and cash flows. ~~During~~For example, during the first quarter of 2020, we experienced an increase in the sales cycle for our products with many customers. While we believe that increase could have been a result of a number of factors, it is possible that the pandemic contributed to the increase and that an increase could happen again in the future during the ongoing course of the pandemic. 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 first quarter of 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~~Over the course of the pandemic, we have sought to ameliorate these negative sales impacts in a number of ways, including 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,~~environment. As a result of those efforts, during the pandemic to date, we do not believe the pandemic has negatively and materially affected our business and operations, results of operations, financial condition, or cash flows. However, there ~~can be~~is no assurance that these efforts will continue to be ~~successful.~~successful, and we potentially could experience these adverse effects in the future if the pandemic worsens, including in connection with the potential future emergence of new variants and mutations of the virus.

Non-GAAP Financial Measures

In addition to our results determined in accordance with generally accepted accounting principles in the 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

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 with U.S. GAAP. In particular, free cash flow is not a substitute for cash

~~Table of contents~~

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 with U.S. GAAP. Investors are encouraged to review the related U.S. GAAP financial measures and the reconciliation of these non-GAAP financial measures to their most directly comparable U.S. GAAP financial measures, and not to rely on any single financial measure to evaluate our business.

Non-GAAP ~~Loss~~Income (Loss) from Operations and Non-GAAP Operating Margin

We define non-GAAP ~~loss~~income (loss) from operations and non-GAAP operating margin as U.S. GAAP loss from operations and U.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 Class A 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.

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 that is available (or not available) to be used for strategic initiatives. For example, if free cash flow is negative, we

Table of contents

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.

Key Business Metrics

In addition to our results determined in accordance with U.S. GAAP and the non-GAAP measures discussed above, we also review the key business metrics discussed below to assist us in evaluating our business, measuring performance, identifying trends, formulating business plans, and making strategic decisions. 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 ended March 31, 2020, we 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 network provides a key indicator of growth of our business and our future business opportunities. We define a paying customer at the end of the quarter as a person or entity who has generated revenue during such 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 ~~126,735~~132,390 and ~~96,178~~100,968 as of ~~June~~September 30, 2021 and ~~June~~September 30, 2020, 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 $100,000 as indicative of our penetration within large enterprise accounts. To measure Annualized Revenue at the

Table of contents

end of a quarter, 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 $1,800 of revenue in a quarter, that customer would account for $7,200 of Annualized Revenue for that year. Our Annualized Revenue calculation excludes (i) agreements that

~~Table of contents~~

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 ~~1,088~~1,260 and ~~637~~736 as of ~~June~~September 30, 2021 and ~~June~~September 30, 2020, 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 network.

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 network. 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 quarter, 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 professional services and 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 ended ~~June~~September 30, 2021 and ~~June~~September 30, 2020 were 124% and ~~115%~~116%, respectively.

Components of Our Results of Operations

Revenue

We generate revenue primarily from sales to our customers of subscriptions to access our network and products, 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 network. Instead, customers are granted continuous access to our network 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 network 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

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 network and products driven by additional applications and connected devices, we expect that our cost of revenue will increase due to higher network and bandwidth costs

~~Table of contents~~

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 network and products. We intend to continue to invest additional resources in our global network and products 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 network, 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 network. 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 network and products. We expect our research and development expenses to remain generally consistent 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.

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)

~~Table of contents~~

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 due ~~May~~ 2025 (the 2025 Notes) ~~that were issued~~and $1,293.8 million aggregate principal amount of 0% Convertible Senior Notes due 2026 (the 2026 Notes, and together with the 2025 Notes, the Notes).

Loss on Extinguishment of Debt

Loss on extinguishment of debt consists of loss recognized from privately-negotiated exchange agreements with certain holders of the 2025 Notes to exchange approximately $400.0 million in ~~May 2020.~~aggregate principal amount of the 2025 Notes for an aggregate of $400.7 million in cash (including accrued interest) and approximately 7.6 million shares of our Class A common stock (the 2025 Notes Exchange).

Other Income, Net

Other income, net consists primarily of gain on sale of property and equipment and foreign currency transaction gains and losses.

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 in the 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.

Research and development expenses increased by ~~$19.4~~$35.3 million, or ~~32%~~38%, for the ~~six~~nine months ended ~~June~~September 30, 2021 compared to the ~~six~~nine months ended ~~June~~September 30, 2020. The increase was primarily driven by ~~$15.7~~$28.1 million in increased employee-related costs, ~~due to a 31% increase in headcount in our research and development organization from June 30, 2020 to June 30, 2021,~~ including an increase of ~~$6.3~~$10.8 million in stock-based compensation expense. These increases in employee-related costs were partially offset by a decrease of $5.7 million in compensation-related payments to former employees of S2 ~~employees,~~Systems Corporation (S2), which was recognized in the three months ended March 31, 2020. The remainder of the increase was primarily a result of decreased capitalized internal-use software development costs of ~~$3.7~~$5.1 million.

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 network and products. In September 2019, we completed our initial public offering (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. In May 2020, we issued $575.0 million aggregate principal amount of the 2025 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. In August 2021, we issued $1,293.8 million aggregate principal amount of the 2026 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 $1,274.0 million. In August 2021, we also entered into privately-negotiated exchange agreements with certain holders of the 2025 Notes to exchange approximately $400 million in aggregate principal amount of the 2025 Notes for an aggregate of $400.7 million in cash (including accrued interest) and approximately 7.6 million shares of our Class A common stock.

As of ~~June~~September 30, 2021, we had cash and cash equivalents of ~~$247.6~~$618.2 million, including ~~$8.4~~$11.2 million held by our foreign subsidiaries. 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 ~~$786.0~~$1,195.6 million consisting of U.S. treasury securities, U.S. government agency securities, commercial paper, and corporate bonds. As of ~~June~~September 30, 2021, the Company's investment portfolio consisted of 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 ~~$496.0~~$603.3 million as of ~~June~~September 30, 2021 and negative annual 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, the continuing market adoption of our global network and products, 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 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.

Critical Accounting Policies, Significant Judgments and Use of Estimates

Our condensed consolidated financial statements are prepared in accordance with U.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 of ~~August 6,~~November 5, 2021, 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 ended December 31, 2020. There have been no significant changes to these policies for the ~~six~~nine months ended ~~June~~September 30, 2021, except as described in Note 2 to our condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We have operations in the United States and internationally, and we are exposed to market risk in the ordinary course of our business.

Interest Rate Risk

As of ~~June~~September 30, 2021, we had cash and cash equivalents of ~~$247.6~~$618.2 million and available-for-sale securities of ~~$786.0~~$1,195.6 million. The carrying amount of our cash equivalents approximates fair value, due to the short maturities of these instruments. The primary objectives of our investment activities are the preservation of capital, the fulfillment of liquidity needs, and the fiduciary control of cash and investments. Our available-for-sale securities are held for capital preservation purposes. We do not enter into investments for trading or speculative purposes.

Table of contents

Our cash equivalents and our investment portfolio are subject to market risk due to fluctuations in interest rates. Our future investment income may fall short of our expectations due to changes in interest rates or we may suffer losses in principal if we are forced to sell securities that decline in market value due to changes in interest rates. However, because we classify our securities as “available-for-sale,” no gains or losses are recognized due to changes in interest rates unless such securities are sold prior to maturity or declines in fair value are determined to be other-than-temporary.

In ~~May 2020,~~August 2021, we issued ~~$575.0~~$1,293.8 million in aggregate principal amount of the 2026 Notes. The 2026 Notes do not have ~~a fixed annual~~regularly scheduled interest ~~rate;~~payments; therefore, we do not have economic interest rate exposure on the 2026 Notes. We carry the 2026 Notes at face value less the unamortized debt discount and issuance costs on our condensed consolidated balance sheets. Generally, the fair market value of the 2026 Notes will increase as interest rates decline and decrease as interest rates rise. In addition, the fair market value of the 2026 Notes fluctuates when the market price of our Class A common stock fluctuates.

In May 2020, we issued $575.0 million in aggregate principal amount of the 2025 Notes. In August 2021, we entered into privately-negotiated exchange agreements with certain holders of the 2025 Notes to exchange approximately $400 million in aggregate principal amount of the 2025 Notes for an aggregate of $400.7 million in cash (including accrued interest) and approximately 7.6 million shares of our Class A common stock. The 2025 Notes have a fixed annual interest rate; therefore, we do not have economic interest rate exposure on the 2025 Notes. We carry the 2025 Notes at face value less the unamortized debt discount and issuance costs on our condensed consolidated balance sheets. Generally, the fair market value of the 2025 Notes will increase as interest rates decline and decrease as interest rates rise. In addition, the fair market value of the 2025 Notes fluctuates when the market price of our Class A common stock fluctuates.

We do not believe a hypothetical 10% increase or decrease in interest rates during any of the periods presented would have a material impact on our condensed consolidated financial statements.

Foreign Currency Risk

The functional currency of our foreign subsidiaries is the U.S. dollar and our results of operations and cash flows are subject to fluctuations due to changes in foreign currency exchange rates relative to the U.S. dollar. The majority of our revenue is denominated in U.S. dollars. Our expenses are generally denominated in the currencies of the countries in which our operations are located and are subject to fluctuations due to changes in foreign currency

~~Table of contents~~

exchange rates, particularly changes in the British Pound, Euro, and Singapore Dollar. As exchange rates may fluctuate significantly between periods, revenue and operating expenses, when converted into U.S. dollars, may also experience significant fluctuations between periods. During the ~~six~~nine months ended ~~June~~September 30, 2021 and 2020, a hypothetical 10% change in foreign currency exchange rates applicable to our business would not have had a material impact on our condensed consolidated financial statements. To date, we have not had a formal hedging program with respect to foreign currency, but we may do so in the future if our exposure to foreign currency should become more significant.

Item 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our disclosure controls and procedures are designed to ensure that information we are required to disclose in reports that we file or submit under the Securities Exchange Act of 1934, as amended (the Exchange Act) is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Our management, with the participation and supervision of our Chief Executive Officer and our Chief Financial Officer, have evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that as of such date, our disclosure controls and procedures were, in design and operation, effective at a reasonable assurance level.

Table of contents

Changes in Internal Controls Over Financial Reporting

There were no changes in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the period covered by this Quarterly Report on Form 10-Q that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on the Effectiveness of Controls

The effectiveness of any system of internal control over financial reporting, including ours, is subject to inherent limitations, including the exercise of judgment in designing, implementing, operating, and evaluating the controls and procedures, and the inability to eliminate misconduct completely. Accordingly, in designing and evaluating the disclosure controls and procedures, management recognizes that any system of internal control over financial reporting, including ours, no matter how well designed and operated, can only provide reasonable, not absolute assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs. Moreover, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. We intend to continue to monitor and upgrade our internal controls as necessary or appropriate for our business but cannot assure you that such improvements will be sufficient to provide us with effective internal control over financial reporting.

PART II - OTHER INFORMATION

Item 1. LEGAL PROCEEDINGS

From time to time we are subject to legal proceedings and claims arising in the ordinary course of business. We are not presently a party to any legal proceeding that we believe is likely to have a material impact on our business, results of operations, or financial condition.

Future litigation may be necessary, among other things, to defend ourselves or our customers by determining the scope, enforceability, and validity of third-party proprietary rights or to establish our proprietary rights. The results of any litigation cannot be predicted with certainty, particularly in the areas of unsettled and evolving law in which we operate, and an unfavorable resolution in any legal proceedings could materially affect our future business, results of operations, or financial condition. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources, and other factors. For additional information, see "Risk Factors - Activities of our paying and free customers or the content of their websites and other Internet properties could subject us to liability" and "We are currently, and may be in the future, party to intellectual property rights claims and other litigation matters that, if resolved adversely, could have a material impact on our business, results of operations, or financial condition" and Note 8 to the condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q.

Item 1A. RISK FACTORS

Our business involves significant risks, some of which are described below. You should carefully consider the risks and uncertainties described below, together with all of the other information in this Quarterly Report on Form 10-Q, including the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our condensed consolidated financial statements and related notes. Any of the following risks could have an adverse effect on our business, results of operations, financial condition, or prospects, and could cause the trading price of our Class A common stock to decline. Our business, results of operations, financial condition, or prospects could also be harmed by risks and uncertainties that are not presently known to us or that we currently believe are not material. In that event, the market price of our Class A common stock could decline, and you could lose part or all of your investment.

Risks Related to Our Business and Our Industry

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.

~~In March 2020, the World Health Organization declared~~The global COVID-19 ~~a global pandemic. This~~ pandemic, which has continued ~~to spread~~since March 2020 and which has mutated into more contagious and dangerous variants (including the ~~increasingly~~ widespread "Delta variant"), and the related adverse public health developments, including travel restrictions and bans, quarantines, shelter-in-place orders, and mandated business closures, have adversely affected workforces, organizations, governments, customers, economies, and financial markets globally, leading to an economic downturn and increased market volatility. Vaccines for COVID-19 have been developed and are being administered in the United States and other countries around the world, but the expansion of administering these vaccines to additional people within these and other countries, the long-term efficacy of these vaccines, and the receptivity of many people to receiving these vaccines, all remain uncertain. The ongoing COVID-19 pandemic has also disrupted the normal operations of many businesses, including ours and those of our customers, vendors, and partners. For example, in response to the initial outbreak of COVID-19, we activated our business continuity plan and took several precautionary steps early to safeguard our business and our people, including implementing travel bans and restrictions, temporarily closing offices and transitioning to a fully remote working environment, and canceling participation in various industry events.

The ongoing COVID-19 pandemic, as well as intensified measures undertaken from time to time in various countries and territories to contain the spread of COVID-19, including ~~new~~widespread variants such as the Delta variant, could decrease the spending of our existing and potential new customers, adversely affect demand for our products,

~~Table of contents~~

cause one or more of our customers, vendors, and partners to file for bankruptcy protection or go out of business,

Table of contents

cause one or more of our customers to fail to renew, terminate, or renegotiate their contracts with us, affect the ability of our sales team to travel to potential customers, impact expected spending from existing and potential new customers, and negatively impact collections of accounts receivable, all of which could adversely affect our business, results of operations, and financial condition. Further, during the first quarter of 2020, the sales cycle for a new customer of our technology and services lengthened and could lengthen again in the future, resulting in a potentially longer delay between increasing operating expenses and the generation of corresponding revenue, if any. During the first quarter of 2020, we also experienced an increase in new and existing customers requesting concessions in terms of payment amounts and/or timing and earlier or additional termination rights and it is possible that similar requests could occur in the future as the pandemic continues. The COVID-19 pandemic also presents challenges as substantially all of our workforce is currently working remotely and assisting new and existing customers who are in many circumstances also ~~generally~~ working remotely.

Any of the negative impacts of the ongoing COVID-19 pandemic, including those described above, alone or in combination with others, may have a material adverse effect on our business and operations, results of operations, financial condition, and cash flows. Any of these negative impacts, alone or in combination with others, also could exacerbate many of the other risk factors discussed below in this Part II, Item 1A “Risk Factors” of this Quarterly Report on Form 10-Q. The full extent to which the COVID-19 pandemic will negatively affect our business and operations, results of operations, financial condition, and cash flows will depend on future developments that are highly uncertain and cannot be predicted, including the scope, severity, and duration of the pandemic and actions taken by governmental authorities and other third parties in response to the pandemic.

We have a history of net losses and may not be able to achieve or sustain profitability in the future.

We have incurred net losses in all periods since we began operations and we ~~expect we will continue to incur net losses for~~may not achieve or maintain profitability in the ~~foreseeable~~ future. We experienced net losses of ~~$35.5~~$107.3 million and ~~$26.1~~$26.5 million for the three months ended ~~June~~September 30, 2021 and 2020, respectively, and ~~$75.5~~$182.8 million and ~~$58.9~~$85.3 million for the ~~six~~nine months ended ~~June~~September 30, 2021 and 2020, respectively, and as of ~~June~~September 30, 2021, we had an accumulated deficit of ~~$496.0~~$603.3 million. Because the markets for our products are rapidly evolving, it is difficult for us to predict our future results of operations. We expect our operating expenses to increase over the next several years as we continue to hire additional personnel, expand our operations and infrastructure both domestically and internationally, and continue to develop our products. In addition to the expected costs to grow our business, we also are incurring significant additional legal, accounting, and other expenses as a public company, as described in greater detail in the risk factors below. If we fail to increase our revenue to offset the increases in our operating expenses, we may not achieve or sustain profitability in the future.

We have experienced rapid revenue growth, which may not be indicative of our future performance.

We have experienced rapid revenue growth in recent periods, with revenue of ~~$152.4~~$172.3 million and ~~$99.7~~$114.2 million for the three months ended ~~June~~September 30, 2021 and 2020, respectively and ~~$290.5~~$462.8 million and ~~$191.0~~$305.1 million for the ~~six~~nine months ended ~~June~~September 30, 2021 and 2020, respectively. You should not consider our recent growth in revenue as indicative of our future performance. In particular, our revenue growth rates may slow or decline in the future and may not be sufficient to achieve and sustain profitability, as we also expect our costs to increase in future periods. We believe that historical comparisons of our revenue may not be meaningful and should not be relied upon as an indication of future performance. Accordingly, you should not rely on our revenue and other growth for any prior quarter or year as an indication of our future revenue or revenue growth.

Our rapid growth may also make it difficult to evaluate our future prospects. Our ability to forecast our future results of operations is subject to a number of uncertainties, including our ability to effectively plan for and model future growth. If we fail to achieve the necessary level of efficiency in our organization as it grows, or if we are not able to accurately forecast future growth, our business, results of operations, and financial condition could be harmed.

If we are unable to attract new paying and free customers, our future results of operations could be harmed.

The success of our business principally depends on our ability to attract new paying and free customers. To do so, we must persuade decision makers at potential customers that our products offer significant advantages over those of our competitors. Other factors, many of which are out of our control, may now or in the future impact our ability to add new paying and free customers, including:

~~Table of contents~~

•potential customers’ commitments to existing equipment or vendors;

Table of contents

•potential customers’ greater familiarity and/or comfort with on-premises, appliance-based products;

•actual or perceived switching costs;

•our failure to obtain or maintain government or industry security certifications for our network and products;

•negative media, industry, or financial analyst commentary regarding our products and the identities and activities of some of our paying and free customers;

•the adoption of new, or amendment of existing, laws, rules, or regulations that negatively impact the utility of our network and products;

•our failure to expand, retain, and motivate our sales and marketing personnel;

•our failure to develop or expand relationships with existing channel partners or to attract new channel partners;

•our failure to help our customers to successfully deploy and use our products;

•our failure to educate our customers about our network and products;

•the perceived risk, commencement, or outcome of litigation; and

•deteriorating general economic conditions, including as a result of the ongoing COVID-19 pandemic.

If our efforts to attract new paying customers are not successful, our revenue and rate of revenue growth may decline, we may not achieve profitability, and our future results of operations could be materially harmed. If our efforts to attract new free customers are not successful, the benefits to our network and product development cycles from our strategy of providing a free subscription plan will be diminished.

Our business depends on our ability to retain and upgrade paying customers and, to a lesser extent, convert free customers to paying customers, and any decline in renewals, upgrades, or conversions could adversely affect our future results of operations.

Our business is subscription-based and it is important for our business and financial results that our paying customers renew their subscriptions for our products when existing contract terms expire. Our pay-as-you-go customers pay with a credit card on a monthly basis and can terminate their subscriptions at will with little advance notice. Because pay-as-you-go customers that subscribe to our basic subscription plans are an important source of revenue, this ease of termination could cause our results of operations to fluctuate significantly from quarter to quarter. Our contracted customers, which consist of customers that sign up for our Enterprise plan, enter into longer term agreements ranging from one to three years, and they generally have no obligation to renew their subscriptions for our products after the expiration of their contractual period and are allowed to cancel their subscriptions in the case of an uncured material breach of the agreement. Some contracted customers also have agreements that allow them to terminate the agreement without cause upon little or no advance written notice, or upon our failure to meet certain service level commitments, or to obtain and maintain industry security certifications within a specified time frame. Should certain of our contracted customers, especially our large customers, terminate their agreements with us, our financial condition and results of operations may materially suffer.

Due to our varied customer base and short average subscription periods, it is difficult to accurately predict our long-term customer retention rate. Our customer retention may decline or fluctuate as a result of a number of factors, including our customers’ satisfaction with the security, performance, and reliability of our products, our prices and subscription plans, our customers’ budgetary restrictions (including reductions in spending as a result of the COVID-19 pandemic), mergers, acquisitions, joint ventures, and business partnerships and relationships involving our customers, the perception that competitive products provide better or less expensive options, negative public perception of us or our free and paying customers, and deteriorating general economic conditions.

Our future financial performance also depends in part on our ability to continue to upgrade paying customers to higher-tier subscriptions or additional paid products and, to a lesser extent, to convert free customers into paying customers. Conversely, our paying customers may convert to lower-cost or free plans if they do not see the marginal value in paying for our higher-cost plans, thereby impacting our ability to increase revenue. Moreover, our free customers have no obligation to transition to paying customers at any point. In order to expand our commercial relationship with our customers, existing paying and free customers must decide that the incremental cost associated with such an upgrade is justified by the additional functionality. For example, some of our paying

~~Table of contents~~

customers may decide that our ~~enterprise~~Enterprise plan offerings do not provide sufficient incremental value to upgrade from

Table of contents

our pay-as-you-go offering. Our customers’ decision whether to upgrade their subscription is driven by a number of factors, including customer satisfaction with the security, performance, and reliability of our network and products, customer security and networking issues and requirements, general economic conditions, and customer reaction to the price for additional products. If our efforts to expand our relationship with our existing paying and free customers are not successful, our financial condition and results of operations may materially suffer.

If we are unable to effectively attract, expand, and retain sales to large customers, or we fail to mitigate the additional risks associated with serving such customers, our business, results of operation, and financial condition may suffer.

Our growth strategy is dependent, in large part, upon attracting, expanding, and retaining sales to large customers. For our definition of “large customers,” see Part I, Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations. Attracting, expanding, and retaining sales to large customers involve risks that may not be present, or that are present to a lesser extent, with sales to smaller customers, including:

•competition from companies that traditionally target larger enterprises and that may have pre-existing relationships or purchase commitments from such customers;

•longer evaluation periods, more detailed evaluations, and more cumbersome contract negotiation and approval processes;

•increased purchasing power and leverage in negotiating contractual arrangements with us;

•requirements for more technically complex configurations, integrations, deployments, or features;

•more stringent requirements in our support and compliance obligations;

•increased usage of our global network that may require us to incur greater network infrastructure expenditures; and

•longer sales cycles and the associated risk that substantial time and resources may be spent on a potential customer that elects not to purchase, expand, or continue to purchase our products.

Historically, the implementation period to start using, or expanding the use of, our products has been short, with most customers under our pay-as-you-go plans implementing usage of our products within a matter of minutes and our sales cycle for customers under our Enterprise plan typically lasting less than one quarter. These implementation periods have remained generally consistent during the ongoing COVID-19 pandemic, subject to some modest lengthening of our average customer sales cycle during the beginning of the pandemic. As our sales force targets an increasing number of large customers for new and expanded product sales, these larger enterprises may undertake a significant evaluation and negotiation process, which could lengthen our sales cycle materially.

In addition, our sales efforts typically involve educating our prospective large customers about the uses, benefits, and value proposition of our network and products. Our sales force develops relationships directly with our customers and our channel partners onthrough account penetration, account coordination, sales, and overall market development. Potential large customers often view the subscription to our products, including any expansion of those subscriptions, as a significant strategic decision and, as a result, in some cases require considerable time to evaluate, test, and qualify our network and products prior to entering into or expanding a relationship with us. As a result, we spend substantial time and resources on our sales efforts without any assurance that our efforts will produce a sale. Subscriptions to our products, including expanded subscriptions, often are subject to budget constraints, multiple approvals, and unanticipated administrative, processing, and other delays. As a result, it is difficult to predict whether or when a sale to a prospective large customer will be completed and when revenue from a subscription will be recognized or will cease.

Further, our ability to improve our sales of products to large customers is dependent on us continuing to attract and retain sales personnel with experience in selling to larger enterprises. Also, because security breaches or a network outage with respect to larger, high-profile enterprises are likely to be heavily publicized, there is increased liability and reputational ~~risk~~risks associated with serving such customers. ~~These additional risks can potentially act as a disincentive to our sales team’s pursuit of these large customers for new or expanded product sales.~~

Once we begin selling to a large customer or expand our sales to a large customer, if we fail to retain the large customer or to retain the same amount of sales to the large customer, then the adverse impact on our result of

~~Table of contents~~

operations and financial conditions could be significant during any specific quarter and could also result in

Table of contents

potentially greater and unexpected variability in our results of operations and financial condition from quarter to quarter.

Activities of our paying and free customers or the content of their websites or other Internet properties, as well as our response to those activities, could cause us to experience significant adverse political, business, and reputational consequences with customers, employees, suppliers, government entities, and others.

Activities of our paying and free customers or the content of their websites and other Internet properties could cause us to experience significant adverse political, business, and reputational consequences with customers, employees, suppliers, government entities, and other third parties. Even if we comply with legal obligations to remove or disable customer content, we may maintain relationships with customers that others find hostile, offensive, or inappropriate. For example, we experienced significant negative publicity in connection with the use of our network by The Daily Stormer, a neo-Nazi, white supremacist website, around the time of the 2017 protests in Charlottesville, Virginia. We also received negative publicity in connection with the use of our network by 8chan, a forum website that served as inspiration for the 2019 attacks in El Paso, Texas and Christchurch, New Zealand. We are aware of some potential customers that have indicated their decision to not subscribe to our products was impacted, at least in part, by the actions of certain of our paying and free customers. We may also experience other adverse political, business and reputational consequences with prospective and current customers, employees, suppliers, and others related to the activities of our paying and free customers, especially if such hostile, offensive, or inappropriate use is high profile.

Conversely, actions we take in response to the activities of our paying and free customers, up to and including banning them from using our products, may harm our brand and reputation. Following the events in Charlottesville, Virginia, we terminated the account of The Daily Stormer. Similarly, following the events in El Paso, Texas, we terminated the account of 8chan. We received significant adverse feedback for these decisions from those concerned about our ability to pass judgment on our customers and the users of our network and products, or to censor them by limiting their access to our products, and we are aware of potential customers who decided not to subscribe to our products because of this.

Although offering a free plan for certain of our products is an important part of our business strategy, we may not be able to realize all of the expected benefits of this strategy and the costs and other detriments associated with our free plan could outweigh the benefits we receive from our free customers.

We have historically offered a free plan for certain of our products. We believe that this strategy is valuable to us and it is an important part of our overall business strategy. However, to the extent that we do not achieve the expected benefits of this strategy, our business may be adversely affected by the costs and detriments of making certain of our products available on a free basis. While we do not receive any revenue from our free customers, we bear incremental expenses and other liabilities as a result of our free customers’ continuing free access to our network and certain of our products. Adverse political, business, and reputational consequences associated with Internet properties we serve that are perceived as hostile, offensive, or inappropriate may also be disproportionately common among our free customers. The vast majority of our customers do not pay for our products. In addition, a substantial majority of our free customers historically have not converted to paying customers and we expect this will continue in the future.

We face intense and increasing competition, which could adversely affect our business, financial condition, and results of operations.

The markets for our network and products are intensely competitive and characterized by rapid changes in technology, customer requirements, industry standards, and frequent introductions of new, and improvements of, existing products. Our broad portfolio of products exposes us to competition from a large number of competitors in a number of different markets, including companies and their product and services offerings in, among others, virtual private networks, internal and external firewalls, web security (including web application firewalls and content filtering), distributed denial of service prevention, intrusion detection and prevention, application delivery controls, content delivery networks, domain name systems, advanced threat prevention, and wide area network (WAN) technology.

Our competitors provide both on-premises, appliance-based solutions, and cloud-based services that have functionality similar to our network and products. We expect competition to increase as other established and

~~Table of contents~~

emerging companies and start-ups enter the markets for products and solutions for security, performance, and

Table of contents

reliability, in particular with respect to cloud-based solutions, as customer requirements evolve and as new products, services, and technologies are introduced. If we are unable to anticipate or effectively react to these competitive challenges, our competitive position could weaken, and we could experience a decline in revenue or our growth rate that could materially and adversely affect our business and results of operations.

Our potential competitors include large companies with substantial infrastructure, such as global telecommunications services provider partners and public cloud providers. These companies could choose to enter the markets for products and solutions for security, performance, and reliability, including by acquiring existing companies, developing their own internal solutions, or establishing cooperative relationships with businesses that may allow them to offer more comprehensive solutions or to offer solutions for lower prices or to adapt more quickly than us to new technologies and customer needs. Additionally, if an increasing portion of web content is housed on another company’s network or portions of the Internet are otherwise privatized, it could reduce the demand for our products and increase competitive pressure on us. These competitive pressures in our markets or our failure to compete effectively may result in price reductions, fewer subscriptions, reduced revenue and gross margin, increased net losses, and loss of market share.

Our current and potential future competitors include a number of different types of companies, including:

•on-premise hardware network vendors, such as Cisco Systems Inc., F5 Networks, Inc., Check Point Software Technologies Ltd., FireEye, Inc., Imperva, Inc., Palo Alto Networks, Inc., Juniper Networks, Inc., Riverbed Technology, Inc., and Broadcom Inc.;

•point-cloud solution vendors, including cloud security vendors such as Zscaler, Inc., Cisco Systems Inc. through Umbrella, ~~(formerly known as OpenDNS),~~ and Menlo Security, Inc., content delivery network vendors such as Akamai Technologies, Inc., Limelight Networks, Inc., Fastly, Inc., and Verizon Communications Inc. through Edgecast, domain name system vendors services such as Oracle Corporation through DYN, NeuStar, Inc., and UltraDNS Corporation, and cloud SD-WAN vendors; and

•traditional public cloud vendors, such as Amazon.com, Inc. through Amazon Web Services, Alphabet Inc. through Google Cloud Platform, Microsoft Corporation through Azure, and Alibaba Group Holding Limited through Alibaba Cloud.

Many of our existing and potential competitors have or could have substantial competitive advantages including, among others:

•greater name recognition;

•longer operating histories and larger customer bases;

•larger sales and marketing budgets and capital resources;

•broader distribution and established relationships with partners and customers;

•greater customer support resources;

•greater resources to make acquisitions and enter into strategic partnerships;

•lower labor and research and development costs;

•larger and more mature intellectual property rights portfolios;

•control of significant technologies, standards, or networks, including operating systems, with which our products must interoperate;

•higher or more difficult to obtain security certifications than we possess; and

•substantially greater financial, technical, and other resources.

In particular, some of our larger competitors have substantially broader and more diverse product and services offerings, which may allow them to leverage existing commercial relationships, incorporate functionality into existing products, sell products and services with which we compete at zero or negative margins, offer fee waivers and reductions or other economic and non-economic concessions, bundle products and solutions, maintain closed technology platforms, or render our products unable to interoperate with such platforms. If they were to engage in predatory practices, it could harm our existing product offerings or prevent us from creating viable products in other segments of the markets in which we participate. If our competitors are able to exploit their advantages or are able

6065

Table of contents

to persuade our customers or potential customers that their products are superior to ours, we may not be able to compete effectively and our business, financial condition, and results of operations may be materially affected.

If we do not effectively expand, train, and retain our sales force, we may be unable to add new contracted customers, or increase sales to our existing customers and our business would be adversely affected.

A majority of our revenue in the ~~six~~nine months ended ~~June~~September 30, 2021 was from contracted customers that were acquired through our inside and field sales teams. We expect this trend will continue for the foreseeable future. As a result, our financial condition and results of operations are dependent to a significant degree on the ability of our dedicated sales personnel to acquire new contracted customers and expand our relationships with our existing contracted customers. Our sales representatives typically engage in direct interaction with our prospective contracted customers. Increasing our customer base and achieving broader market acceptance of our network and products will depend, to a significant extent, on our ability to expand and further invest in our sales and marketing operations and activities. There is significant competition for sales personnel with the advanced sales skills and technical knowledge we need. We believe that selling subscriptions to our products requires particularly talented sales personnel that understand both cloud-based and appliance-based solutions, as well as the key differences between them. Our ability to achieve significant growth in revenue in the future will depend, in large part, on our success in recruiting, training, and retaining sufficient numbers of these talented sales personnel in both the United States and international markets. As we continue to focus on revenue growth, we are seeking to increase our rate of hiring sales personnel and any delays in making these sales hires could have an adverse impact on our ability to increase revenue, particularly with respect to our sales to contracted customers. In addition, new sales hires require significant training and may take significant time before they achieve full productivity. As a result, our new sales hires and planned sales hires may not become as productive as we would like or as quickly as we expect, and we may be unable to hire or retain sufficient numbers of qualified individuals. As a result of our rapid growth, a large percentage of our sales team is new to our company and inexperienced in selling subscriptions to our products, and therefore these personnel may be less effective than our more seasoned employees. Experienced sales personnel are particularly sought after in our industry and we may have to expend significant resources to retain our most productive sales employees. Even with considerable effort, we may be unsuccessful at retaining our experienced sales employees, which would adversely impact our business, results of operations, and financial condition.

Furthermore, hiring sales personnel in new countries, or expanding our existing presence in the countries in which we currently operate, requires upfront and ongoing expenditures that we may not recover if the sales personnel fail to achieve full productivity or that may be recovered on a more delayed basis than expected. We cannot predict whether, or when or to what extent, our sales will increase as we expand our sales force or how long it will take for sales personnel to become productive. If we are unable to hire, train, and retain a sufficient number of effective sales personnel, or the sales personnel we hire are not successful in obtaining new customers or increasing sales to our existing customer base, our business and future growth prospects will be materially and adversely affected.

If we fail to effectively manage our growth, we may be unable to execute our business plan, maintain high-quality levels of customer support, ensure the reliability and security of our network, adequately address competitive challenges, or maintain our corporate culture, and our business, financial condition, and results of operations would be harmed.

We have recently experienced, and continue to experience, a period of rapid growth. For example, our headcount grew from ~~1,535~~1,697 employees as of ~~June~~September 30, 2020 to ~~2,050~~2,240 employees as of ~~June~~September 30, 2021. We also have offices around the world, including offices in Beijing and Munich that we opened during 2018 and offices in Sydney and Lisbon that we opened in 2019. In 2020, we opened offices in Paris, Tokyo, and ~~Toronto.~~we opened an office in Toronto in 2021. The number of customers, users, and requests on our network also has increased rapidly in recent years. While we expect to continue to expand our operations and to increase our headcount, network, and products significantly in the future, both domestically and internationally, our growth may not be sustainable. Our growth has placed, and future growth will continue to place, a significant strain on our management and our administrative, operational, and financial infrastructure. Our success will depend in part on our ability to manage this growth effectively, which will require that we continue to improve our administrative, operational, financial, and management systems and controls by, among other things:

•effectively attracting, training, and integrating a large number of new employees, particularly members of our sales, engineering, and management teams;

•ensuring the integrity and security of our network and IT infrastructure throughout the world;

Table of contents

•maintaining our corporate culture, which we believe fosters innovation, teamwork, and an emphasis on customer-focused results and contributes to our cost-effective business model;

•further improving our key business applications, processes, and IT infrastructure, including our core co-location facilities, to support our business needs;

•enhancing our information and communication systems to ensure that our employees and offices around the world are well coordinated and can effectively communicate with each other and our growing base of channel partners, customers, and users;

•maintaining high levels of customer support; and

•appropriately documenting and testing our IT systems and business processes.

Managing our growth will require significant capital expenditures and allocation of valuable management and employee resources. If we fail to manage our expected growth, the uninterrupted and secure operation of our network and products and key business systems, our corporate culture, our compliance with the rules and regulations applicable to our operations, the quality of our products, and our ability to compete could suffer. Any failure to preserve our culture also could further harm our ability to retain and recruit personnel, innovate and create new products, operate effectively, and execute on our business strategy.

Our quarterly results may fluctuate significantly and may not fully reflect the underlying performance of our business.

Our quarterly results of operations, including, without limitation, our revenue, gross margin, operating margin, profitability, cash flow from operations, and deferred revenue, may vary significantly in the future and period-to-period comparisons of our results of operations may not be meaningful. Accordingly, the results of any one quarter should not be relied upon as an indication of future performance. Our quarterly results of operations may fluctuate as a result of a variety of factors, many of which are outside of our control, and as a result, may not fully reflect the underlying performance of our business. Fluctuation in quarterly results may negatively impact the trading price of our Class A common stock. Factors that may cause fluctuations in our quarterly results of operations include, without limitation:

•our ability to attract new paying customers and, to a lesser extent, convert free customers to paying customers;

•our ability to retain and upgrade paying customers;

•the timing of expenses and recognition of revenue;

•the amount and timing of operating expenses related to the maintenance and expansion of our business, operations, and infrastructure, as well as entry into operating and capital leases and co-location, interconnection, and similar agreements related to the expansion of our network;

•the timing of expenses related to acquisitions;

•any large indemnification payments to our customers or other third parties;

•changes in our pricing policies or those of our competitors;

•the timing and success of new product feature and service introductions by us or our competitors;

•network outages or actual or perceived security breaches;

•our involvement in litigation or regulatory enforcement efforts, or the threat thereof;

•changes in the competitive dynamics of our industry, including consolidation among competitors;

•the length of the sales cycle for our contracted customers;

•changes in laws and regulations that impact our business; and

•general political, economic, market, and social conditions.

For example, the full impact of the ongoing COVID-19 pandemic is unknown at this time but could result in material adverse changes in our results of operations for an unknown period of time as the virus and its related political, social, and economic impacts spread.

We rely on our key technical, sales, and management personnel to grow our business, and the loss of one or more key employees or the inability to attract and retain qualified personnel could harm our business.

Our future success is substantially dependent on our ability to attract, retain, and motivate the members of our management team and other key employees throughout our organization, particularly Matthew Prince, our Chief Executive Officer, and Michelle Zatlyn, our President and Chief Operating Officer. We rely on our leadership team in the areas of operations, security, marketing, sales, support, research and development, and general and administrative functions, and on individual contributors on our research and development team. Although we have entered into employment offer letters with our key personnel, these agreements have no specific duration and constitute at-will employment. We do not maintain key person life insurance policies on any of our employees. The loss of one or more of our executive officers or key employees could seriously harm our business.

To execute our growth plan, we must attract and retain highly qualified personnel. In particular, it is critical for us to attract and retain engineering talent in our fast growing industry. Competition for these personnel in the San Francisco Bay Area, where our headquarters is located, and in London, Singapore, Austin, Texas, and other locations where we maintain offices, is intense, especially for experienced sales professionals and for engineers experienced in designing and developing cloud applications. We have from time to time experienced, and we expect to continue to experience, difficulty in hiring and retaining employees with appropriate qualifications. For example, in recent years, recruiting, hiring, and retaining employees with expertise in the cybersecurity industry has become increasingly difficult as the demand for cybersecurity professionals has increased as a result of high-profile cybersecurity attacks on global corporations and governments. Many of the companies with which we compete for experienced personnel have greater resources than we have and may provide higher levels of ~~compensation.~~compensation or benefits. In addition, job candidates and existing employees often consider the value of the equity awards they receive in connection with their employment. Volatility or lack of performance in our stock price may affect our ability to attract and retain our key employees. Upon vesting of equity awards, many of our employees have acquired or may soon acquire a substantial amount of personal wealth. This may make it more difficult for us to retain and motivate these employees, and this wealth could affect their decision about whether or not they continue to work for us. Any failure to successfully attract, integrate, or retain qualified personnel to fulfill our current or future needs could materially and adversely affect our business, results of operations, and financial condition.

We believe our long-term value as a company will be greater if we focus on growth, which may negatively impact our profitability.

A significant part of our business strategy is to focus on long-term growth. For example, we increased our operating expenses to ~~$146.3~~$161.3 million from ~~$100.3~~$108.4 million in the three months ended ~~June~~September 30, 2021 and 2020, respectively, and increased our operating expenses to ~~$283.5~~$444.8 million from ~~$206.8~~$315.2 million in the ~~six~~nine months ended ~~June~~September 30, 2021 and 2020 respectively. In the three months ended ~~June~~September 30, 2021 and 2020 our net loss increased to ~~$35.5~~$107.3 million from ~~$26.1~~$26.5 million, respectively and in the ~~six~~nine months ended ~~June~~September 30, 2021 and 2020, our net loss increased to ~~$75.5~~$182.8 million from ~~$58.9~~$85.3 million, respectively. As a result, we may continue to operate at a loss or our profitability may be lower than it would be if our strategy were to maximize short-term profitability. Significant expenditures on sales and marketing efforts, and expenditures on growing our network and expanding our research and development and portfolio of products, each of which we intend to continue to invest in, may not ultimately grow our business or cause long-term profitability. If we are ultimately unable to achieve or improve profitability at the level or during the time frame anticipated by industry or financial analysts and our stockholders, our stock price may decline.

If we are not able to maintain our brand, our business and results of operations may be adversely affected.

We believe that maintaining our reputation as a provider of products with the highest levels of security, performance, and reliability is critical to our relationship with our existing customers and our ability to attract new customers. The successful promotion of our brand will depend on a number of factors, including the reliability of our network on which we provide our products and the record of security, performance, and reliability of our products; our marketing efforts; our ability to continue to develop high-quality features and products for our network; and our ability to successfully differentiate our products from competitive products and services. Our brand promotion activities may not be successful or yield increased revenue.

Independent industry and financial analysts often provide reviews of our products, as well as those of our competitors. Perception of our offerings in the marketplace may be significantly influenced by these expert reviews. In addition, the difficulty or inability of us to periodically provide certain types of financial information about our

Table of contents

business and products requested by industry analysts could adversely impact these analysts’ reviews of our

~~Table of contents~~

products. If reviews of our products are negative, or less positive than those of our competitors’, our brand may be adversely affected. The performance of our channel partners also may affect our brand and reputation, particularly if customers do not have a positive experience with our channel partners. The promotion of our brand requires us to make substantial expenditures, and we anticipate that the expenditures will increase as our markets become more competitive and we expand into new markets. Expenditures intended to maintain and enhance our brand may not be cost-effective or effective at all. If we do not successfully maintain and enhance our brand, we may have reduced pricing power relative to our competitors, we could lose customers, or we could fail to attract potential new customers or expand sales to our existing customers, all of which could materially and adversely affect our business, results of operations, and financial condition.

Adverse economic conditions, including reduced spending on products and solutions for network security, performance, and reliability, may adversely impact our revenue and profitability.

Our operations and financial performance depend in part on worldwide economic conditions and the impact these conditions have on levels of spending on products and solutions for network security, performance, and reliability. Our business depends on the overall demand for these products and on the economic health and general willingness of our current and prospective customers to purchase our products. For example, the full impact of the ongoing COVID-19 pandemic is unknown at this time but has resulted in a material adverse impact on economic conditions in the United States and in other countries throughout the world, including significant increases in unemployment, reduced demand for products and services across a variety of industries, and other related harms. Some of our paying customers may view a subscription to our products as a discretionary purchase and may reduce their discretionary spending on our products during an economic downturn. Weak economic conditions, including a reduction in spending on products and solutions for security, performance, and reliability, could reduce sales, lengthen sales cycles, increase churn, and lower demand for our products, any of which could adversely affect our business, results of operations, and financial condition.

Our relatively limited operating history makes it difficult to evaluate our current business and prospects, and may increase the risk that we will not be successful.

Our relatively limited operating history makes it difficult to evaluate our current business and prospects, and to plan for our anticipated future growth. We began operations in 2010 and much of our growth has occurred in recent years. As a result, our business model has not been fully proven, which subjects us to a number of uncertainties, including our ability to plan for and model future growth. While we have continued to expand our network and develop additional reliability products, we have encountered, and will continue to encounter, risks and uncertainties frequently experienced by rapidly growing companies in developing industries, including our ability to achieve broad market acceptance of our products, attract additional customers, identify and grow partnerships, withstand increasing competition in our existing and future markets, and manage increasing expenses as we continue to grow our business. If our assumptions regarding these risks and uncertainties are incorrect or change in response to changes in the markets for products and solutions for network security, performance, and reliability, our business could suffer and our results of operations and financial condition could differ materially from our expectations.

We have limited experience with our pricing models, and we may not accurately predict the long-term rate of paying customer adoption or renewal, or the impact these will have on our revenue or results of operations.

We generate revenue primarily from subscriptions to our network and products. We offer subscription plans that provide varying degrees of functionality, and also offer separate subscriptions to various add-on products and network functionality. We have limited experience with respect to determining the optimal prices and pricing models for our subscription plans and products, particularly with respect to our newer products and ~~solutions such as Cloudflare for Teams and Magic Transit.~~solutions. As the markets for our products mature, as we enter into newer product markets for our business, or as new competitors introduce new products or services that compete with ours, we may be unable to attract new customers or retain existing customers at the same price or based on the same pricing model as we have used historically. Moreover, our increasing focus on larger customers may lead to greater price concessions in the future or have a more significant impact period to period on our revenue and results of operations. As a result, in the future we may be required to reduce our prices, which could adversely affect our revenue, gross margin, profitability, financial condition, and cash flow.

Table of contents

We also have limited experience in determining which products and functionality to offer as part of our subscription plans and which to offer as add-on products. Our limited experience in determining the optimal manner in which to

~~Table of contents~~

bundle our various products and functionalities could reduce our ability to capture the value delivered by our offerings, which could adversely impact our business, results of operations, and financial condition.

Our growth depends, in part, on the success of our strategic relationships with third parties, and if we fail to continue to expand, grow, and retain these relationships then our business, results of operations, and financial condition may be adversely impacted.

To grow our business, we anticipate that we will continue to depend on relationships with third parties, such as value-added channel partners, referral partners, systems integrators, global platform providers, telecommunications companies, and managed security service providers. We believe developing, expanding, and retaining these strategic relationships will play an increasingly greater role in our sales efforts to our large customers. However, identifying these types of strategic partners, negotiating and documenting our business and contractual relationships with them, and maintaining APIs that some of our strategic partners use to interact with our business, each require significant time and resources. While in some cases our contractual arrangements with our strategic partners have terms of one year or longer, in many cases these arrangements are short-term in nature and can be terminated on 90 days advance notice. Our competitors also may be effective in providing incentives to third parties to favor their products or services over subscriptions to our products. In addition, acquisitions of such partners by our competitors could result in a decrease in the number of our current and potential customers, as these partners may no longer facilitate the adoption of our applications by potential customers. Further, some of our partners are or may become competitive with certain of our products and may elect to no longer integrate with our network and products. If we are unsuccessful in establishing, expanding, or maintaining our relationships with these third parties, our ability to compete in the marketplace or to grow our revenue could be impaired, and our business, results of operations, and financial condition may suffer. Even if we are successful, we cannot assure you that these relationships will result in increased customer usage of our products by, or increased revenue from, our paying customers and large customers.

Our ability to maintain customer satisfaction depends in part on the quality of our customer support. Failure to maintain high-quality customer support could have an adverse effect on our business, results of operation, and financial condition.

We believe that the successful use of our network and products requires a high level of support and engagement for many of our customers, particularly our large customers. In order to deliver appropriate customer support and engagement, we must successfully assist our customers in deploying and continuing to use our network and products, resolving performance issues, addressing interoperability challenges with the customers’ existing IT infrastructure, and responding to security threats and cyber attacks and performance and reliability problems that may arise from time to time. The IT architecture of our contracted customers, particularly the larger organizations, is very complex and may require high levels of focused support to effectively utilize our network and products. Because our network and products are designed to be highly configurable and to rapidly implement customers’ reconfigurations, customer errors in configuring our network and products can result in significant disruption to our customers. Our support organization faces additional challenges associated with our international operations, including those associated with delivering support, training, and documentation in languages other than English. Increased demand for customer support, without corresponding increases in revenue, could increase our costs and adversely affect our business, results of operations, and financial condition.

We also rely on channel partners in order to provide frontline support to some of our customers, including in regions where we do not have a significant physical presence or the customers primarily speak languages other than English. If our channel partners do not provide support to the satisfaction of our customers, we may be required to hire additional personnel and to invest in additional resources in order to provide an adequate level of support, generally at a higher cost than that associated with our channel partners. There can be no assurance that we will be able to hire sufficient support personnel as and when needed, particularly if our sales exceed our internal forecasts. To the extent that we are unsuccessful in hiring, training, and retaining adequate support resources, our ability to provide high-quality and timely support to our customers will be negatively impacted, and our customers’ satisfaction with our network and products could be adversely affected. Any failure to maintain high-quality customer support, or a market perception that we do not maintain high-quality customer support, could adversely affect our reputation, business, results of operations, and financial condition, particularly with respect to our large customers.

Our business depends, in part, on sales to U.S. and foreign government organizations, which are subject to a number of challenges and risks.

~~Table of contents~~

We derive a portion of our revenue from contracts with government organizations, and we believe the success and growth of our business will in part depend on adding additional public sector customers. However, demand from government organizations is often unpredictable, and we cannot assure you that we will be able to maintain or grow our revenue from the public sector. Sales to government entities are subject to substantial additional risks that are not present in sales to other customers, including:

•selling to government agencies can be more highly competitive, expensive, and time-consuming than sales to other customers, often requiring significant upfront time and expense without any assurance that such efforts will generate a sale;

•U.S., European, or other government certification and audit requirements potentially applicable to our network, including the Federal Risk and Authorization Management Program (FedRAMP) in the U.S., are often difficult and costly to obtain and maintain, and failure to do so will restrict our ability to sell to government customers;

•government demand and payment for our products may be impacted by public sector budgetary cycles, funding authorizations, or government shutdowns;

•governments routinely investigate and audit government contractors’ administrative processes and any unfavorable audit could result in fines, civil or criminal liability, further investigations, damage to our reputation, and debarment from further government business;

•governments often require contract terms that differ from our standard customer arrangements, including terms that can lead to those customers obtaining broader rights in our products than would be expected under a standard commercial contract and terms that can allow for early termination; and

•governments may demand better pricing terms and public disclosure of such pricing terms, which may harm our ability to negotiate pricing terms with our non-government customers.

In addition, we must comply with laws and regulations relating to the formation, administration, and performance of contracts with the public sector, including U.S. federal, state, and local governmental organizations, which affect how we and our channel partners do business with governmental agencies. Selling our products to the U.S. government, whether directly or through channel partners, also subjects us to certain regulatory and contractual ~~requirements.~~requirements, including expanded compliance obligations under the Federal Acquisition Regulations (FARs). Failure to comply with these requirements by either us or our channel partners could subject us to investigations, fines, and other penalties, which could have an adverse effect on our business, results of operations, and financial condition. For example, the U.S. Department of Justice (the DOJ) and the General Services Administration (the GSA) have in the past pursued claims against and financial settlements with vendors under the False Claims Act and other statutes related to pricing and discount practices and compliance with certain provisions of GSA contracts for sales to the federal government. The DOJ and GSA continue to actively pursue such claims. Violations of certain regulatory and contractual requirements could also result in us being suspended or debarred from future government contracting. Any of these outcomes could have a material adverse effect on our revenue, results of operations, and financial condition. Any inability to address these risks and challenges could reduce the commercial benefit to us or otherwise preclude us from selling subscriptions to our products to government organizations.

We rely on third-party software for certain essential financial and operational services, and a failure or disruption in these services could materially and adversely affect our ability to manage our business effectively.

We rely on third-party software to provide many essential financial and operational services to support our business, including NetSuite, Salesforce, Atlassian, and Workday. Many of these vendors are less established and have shorter operating histories than traditional software vendors. Moreover, these vendors provide their services to us via a cloud-based model instead of software that is installed on our premises. As a result, we depend upon these vendors to provide us with services that are always available and are free of errors or defects that could cause disruptions in our business processes. Any failure by these vendors to do so, or any disruption in our ability to access the Internet, would materially and adversely affect our ability to manage our operations.

Our business is exposed to risks associated with credit card and other online payment processing methods.

Table of contents

Many of our customers pay for our service using a variety of different payment methods, including credit and debit cards, prepaid cards, direct debit, and online wallets. We rely on internal systems as well as those of third parties to

~~Table of contents~~

process payments. Acceptance and processing of these payment methods are subject to certain rules and regulations and require payment of interchange and other fees. To the extent there are increases in payment processing fees, material changes in the payment ecosystem, such as large re-issuances of payment cards, delays in receiving payments from payment processors, changes to rules or regulations concerning payment processing, loss of payment partners, and/or disruptions or failures in our payment processing systems or payment products, including products we use to update payment information, our revenue, operating expenses, and results of operation could be adversely impacted. In addition, from time to time, we encounter fraudulent use of payment methods, which could impact our results of operations and if not adequately controlled and managed could create negative consumer perceptions of our service. If we are unable to maintain our chargeback rate at acceptable levels, card networks may impose fines and our card approval rate may be impacted. If we fail to comply with the rules or requirements applicable to processing payments, or if our data security systems are breached, compromised, or otherwise unable to detect or prevent fraudulent activity, we may be liable for card issuing banks’ costs, subject to fines and higher transaction fees, and lose our ability to accept certain payments from our customers. The termination of our ability to process payments using any major payment method our business, results of operations, and financial condition could be harmed.

Because we recognize revenue from subscriptions for our products over the term of the subscription, downturns or upturns in new business may not be immediately reflected in our results of operations and may be difficult to discern.

We generally recognize revenue from customers ratably over the term of their subscription, which in the case of our contracted customers range from one to three years and in the case of our pay-as-you-go customers is typically monthly. Consequently, any increase or decline in new sales or renewals to these customers in any one period may not be immediately reflected in our revenue for that period. Any such change, however, may affect our revenue in future periods. Accordingly, the effect of downturns or upturns in new sales and potential changes in our rate of renewals may not be fully reflected in our results of operations until future periods. We may also be unable to reduce our cost structure in line with a significant deterioration in sales or renewals. Our subscription model also makes it difficult for us to rapidly increase our revenue through additional sales in any period, as revenue from new customers must be recognized over the applicable subscription term.

By contrast, a significant majority of our costs are expensed as incurred, which occurs as soon as a customer starts using our network and products. As a result, an increase in customers could result in our recognition of more costs than revenue in the earlier portion of the subscription term. We may not attain sufficient revenue to maintain positive cash flow from operations or achieve profitability in any given period.

If our estimates or judgments relating to our critical accounting policies prove to be incorrect or financial reporting standards or interpretations change, our results of operations could be adversely affected.

The preparation of financial statements in conformity with generally accepted accounting principles in the United States (U.S. GAAP) requires our management to make estimates and assumptions that affect the amounts reported and disclosed in our condensed consolidated financial statements and accompanying notes. We base our estimates and assumptions on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. The results of these estimates form the basis for making judgments about the carrying values of assets, liabilities, and equity, and the amount of revenue and expenses that are not readily apparent from other sources. Significant assumptions and estimates used in preparing our condensed consolidated financial statements include those related to allowance for doubtful accounts, deferred contract acquisitions costs, the period of benefit generated from our deferred contract acquisition costs, the capitalization and estimated useful life of internal-use software, the assessment of recoverability of intangible assets and their estimated useful lives, useful lives of property and equipment, liability and equity allocation of our 0.75% Convertible Senior Notes due ~~May~~ 2025 (the 2025 Notes) and our 0% Convertible Senior Notes due 2026 (the 2026 Notes, and together with the 2025 Notes, the Notes), the determination of the incremental borrowing rate used for operating lease liabilities, the valuation and recognition of stock-based compensation expense, uncertain tax positions, and the recognition and measurement of current and deferred income tax assets and liabilities. Due to the 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 of ~~August 6,~~November 5, 2021, 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

Table of contents

obtained. Our results of operations may be adversely affected if our assumptions change or if actual circumstances differ from those in our assumptions, which could cause our results of operations to fall below the expectations of industry or financial analysts and investors, resulting in a decline in the trading price of our Class A common stock.

~~Table of contents~~

Additionally, we regularly monitor our compliance with applicable financial reporting standards and review new pronouncements and drafts thereof that are relevant to us. As a result of new standards, or changes to existing standards, and changes in their interpretation, we might be required to change our accounting policies, alter our operational policies and implement new or enhance existing systems so that they reflect new or amended financial reporting standards, or we may be required to restate our published financial statements. Such changes to existing standards or changes in their interpretation may have an adverse effect on our reputation, business, financial condition, and profit and loss, or cause an adverse deviation from our revenue and operating profit and loss target, which may negatively impact our results of operations.

Future acquisitions, strategic investments, partnerships, or alliances could be difficult to identify and integrate, divert the attention of key management personnel, disrupt our business, dilute stockholder value, and adversely affect our results of operations, financial condition, and prospects.

Part of our business strategy is to make acquisitions of other companies, products, and technologies. For example, in January 2020, we acquired S2 Systems Corporation, a company that has developed browser isolation technology. We have limited experience in making ~~acquisitions.~~acquisitions and integrating acquired businesses into our company. We also may not be able to find suitable acquisition candidates and we may not be able to complete acquisitions on favorable terms, if at all. If we do complete acquisitions, we may not ultimately strengthen our competitive position or achieve our goals, and any acquisitions we complete could be viewed negatively by customers, developers, or investors. In addition, we may not be able to integrate acquired businesses successfully or effectively manage the combined company following an acquisition. If we fail to successfully integrate our acquisitions, or the people or technologies associated with those acquisitions, into our company, the results of operations of the combined company could be adversely affected. Any integration process will require significant time and resources, require significant attention from management, and disrupt the ordinary functioning of our business, and we may not be able to manage the process successfully, which could adversely affect our business, results of operations, and financial condition. In addition, we may not successfully evaluate or utilize the acquired technology and accurately forecast the financial impact of an acquisition transaction, including accounting charges.

In order to expand our network and product offerings, we also may enter into relationships with other businesses, which could involve joint ventures, preferred or exclusive licenses, additional channels of distribution, or investments in other companies. Negotiating these transactions can be time-consuming, difficult, and costly, and our ability to close these transactions may be subject to third-party approvals, such as government regulatory approvals, which are beyond our control. Consequently, we cannot assure you that these transactions, once undertaken and announced, will close or will lead to commercial benefit for us.

In connection with the foregoing strategic transactions, we may:

•issue additional equity securities that would dilute our stockholders;

•use cash that we may need in the future to operate our business;

•incur debt on terms unfavorable to us or that we are unable to repay;

•incur large charges or substantial liabilities;

•encounter difficulties integrating diverse business cultures; and

•become subject to adverse tax consequences, substantial depreciation, or deferred compensation charges.

These challenges related to acquisitions or other strategic transactions could adversely affect our business, results of operations, financial condition, and prospects.

Certain of our key business metrics could prove to be inaccurate, and any real or perceived inaccuracies may harm our reputation and negatively affect our business.

We rely on assumptions and estimates to calculate certain of our key business metrics, such as dollar-based net retention rate. We regularly review and may adjust our processes for calculating our key business metrics to improve their accuracy. For example, in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2020,

Table of contents

we announced a change in how we will calculate our key business metrics starting during 2020 so that they are now based on revenue instead of billings. For a discussion of the reasons for such change, refer to Item 2 “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Non-GAAP Financial Measures and Key Business Metrics.” Our key business metrics may differ from estimates published by third parties

~~Table of contents~~

or from similarly titled metrics of our competitors due to differences in methodology. If investors or analysts do not perceive our key business metrics to be accurate representations of our business, or if we discover material inaccuracies in our key business metrics, our reputation, business, results of operations, and financial condition would be harmed.

Our management team has limited experience managing a public company.

Most members of our management team have limited experience managing a publicly traded company, interacting with public company investors, and complying with the increasingly complex laws pertaining to public companies. Our management team may not successfully or efficiently manage our company, which is subject to significant regulatory oversight and reporting obligations under the federal securities laws and the continuous scrutiny of securities analysts and investors. These new obligations and constituents require significant attention from our senior management and could divert their attention away from the day-to-day management of our business, which could harm our business, results of operations, and financial condition.

We may need additional capital, and we cannot be certain that additional financing will be available on favorable terms, or at all.

Historically, we have financed our operations primarily through the sale of our equity and equity-linked securities as well as payments received from customers using our global cloud network and products. Although we currently anticipate that our existing cash, cash equivalents, and available-for-sale securities, and cash flow from operations will be sufficient to meet our working capital and capital expenditure needs for at least the next 12 months, we may require additional financing. We evaluate financing opportunities from time to time, and our ability to obtain financing will depend, among other things, on our development efforts, business plans, and operating performance, and the condition of the capital markets at the time we seek financing. We cannot assure you that additional financing will be available to us on favorable terms when required, or at all. If we raise additional funds through the issuance of equity or equity-linked or debt securities, those securities may have rights, preferences or privileges senior to the rights of our Class A common stock, and, in the case of equity or equity-linked securities, our stockholders may experience dilution.

Risks Related to Our Network and Products

Problems with our internal systems, networks, or data, including actual or perceived breaches or failures, could cause our network or products to be perceived as insecure, underperforming, or unreliable, our reputation to be damaged, and our financial results to be negatively impacted.

We face security threats from malicious third parties that could obtain unauthorized access to our internal systems, networks, and data, including the equipment at our network and core co-location facilities. It is virtually impossible for us to entirely mitigate the risk of these security threats and the security, performance, and reliability of our network and products may be disrupted by third parties, including nation-states, competitors, hackers, disgruntled employees, former employees, or contractors. We also face the possibility of security threats from other sources, such as employee or contractor errors, or malfeasance. For example, hostile third parties, including nation-states, may seek to bribe, extort, or otherwise manipulate our employees or contractors to compromise our network and products. While we have implemented security measures internally and have integrated security measures into our network and products, these measures may not function as expected and may not detect or prevent all unauthorized activity, prevent all security breaches, mitigate all security breaches, or protect against all attacks or incidents. For example, we have experienced multiple social engineering attacks where third parties have attempted, and in limited cases succeeded, in breaching our perimeter security. While these attacks did not effectively get beyond our perimeter security and we have not suffered any material consequences as a result of these breaches, we cannot be certain that future breaches will be avoided or, if future breaches are successful, that we will not experience material detrimental impacts. Because the equipment in our network co-location facilities is designed to run all of our products, any insertion of malicious code on, unauthorized access to, or other security breach with respect to, this equipment could potentially impact all of our products running on this equipment. We

may also experience security breaches and other incidents that may remain undetected for an extended period and, therefore, may have a greater impact on our products and the networks and systems used in our business, and the proprietary and other confidential data contained on our network or otherwise stored or processed in our operations, and ultimately on our business. We expect to incur significant costs in our efforts to detect and prevent security breaches and other security-related incidents, and we may face increased costs in the event of an actual or perceived security breach or other security-related incident. Our internal systems are exposed to the same cybersecurity risks and consequences of a breach as our customers and other enterprises, any of which could have an adverse effect on our business or reputation. These cybersecurity risks pose a particularly significant risk to a business like ours that is focused on providing

~~Table of contents~~

highly secure products to customers. With the increase in remote work during the ongoing COVID-19 pandemic, we and our customers face increased risks to the security of infrastructure and data, and we cannot guarantee that our security measures will prevent security breaches. We also may face increased costs relating to maintaining and securing our infrastructure and data that we maintain and otherwise process.

Unauthorized access to, other security breaches of, or security incidents affecting, systems, networks, and data used in our business, including those of our vendors, contractors, or those with which we have strategic relationships, even if not resulting in an actual or perceived breach of our customers’ networks, systems, or data, could result in the loss, compromise or corruption of data, loss of business, reputational damage adversely affecting customer or investor confidence, regulatory investigations and orders, litigation, indemnity obligations, damages for contract breach, penalties for violation of applicable laws or regulations, significant costs for remediation, and other liabilities.

Additionally, in the absence of malicious actions, our network and products may experience errors, failures, vulnerabilities, or bugs that cause our products not to perform as intended. For example, from time to time we are subject to “route leaks” that involve the accidental or, less commonly, illegitimate advertisement of prefixes, or blocks of IP addresses, which propagate across networks such as ours and can lead to incorrect routing of traffic across our network, taking traffic offline, or in extreme cases, potential interception of customers’ traffic by attackers. For example, in June 2019, a route leak spread by a major telecommunications services provider caused significant disruption to our traffic and that of many other providers. Although events like this are outside our control, they could materially harm our reputation and diminish the confidence of our current and potential customers in our network and products. In addition, deployment of our network and products into other computing environments may expose these errors, failures, vulnerabilities, or bugs in our products. Any such errors, failures, vulnerabilities, or bugs may not be found until after they are deployed to our customers and may create the perception that our network and products are insecure, underperforming, or unreliable. For example, in July 2019, we deployed an update to our web application firewall and certain aspects of the related software code resulted in excessive consumption of computing resources across our network, resulting in an outage on our network. In April 2020, our core co-location facility in the U.S. Pacific Northwest experienced an outage of approximately 4-1/2 hours as a result of an error that occurred during planned maintenance activities at that facility and, during the outage, our customers lost access to certain features included in our products. In July 2020, we experienced a configuration error in our backbone network that caused an outage for Internet properties and our products in certain areas lasting approximately 30 minutes. While the June 2019 route leak and the July 2019, April 2020, and July 2020 outages did not have a material impact on our results of operations or financial condition, any similar events that may occur in the future may have a material adverse impact on our results of operations or financial condition. In addition, in the event network outages or similar events occur, these events can require additional capital expenditures to lessen the chance that similar events will occur in the future. We also provide frequent updates and fundamental enhancements to our network and products, which increase the possibility of errors. Our quality assurance procedures and efforts to report, track, and monitor issues with our network may not be sufficient to ensure we detect any such defects in a timely manner. For example, in February 2017, a bug in our software code that processes computer information requests was identified. Instead of the requested data, in certain circumstances this bug, which became known as “Cloudbleed,” caused our servers to output data that was not requested. The erroneous data output by our system included, but was not limited to, a portion of our customers’ secure data. There can be no assurance that our software code is or will remain free from actual or perceived errors, failures, vulnerabilities, or bugs, or that we will accurately route or process all requests and traffic on our network. Given the trillions of Internet requests that route through our network on a monthly basis and the large array of Internet properties (e.g., domains, websites, application programming interfaces (APIs), and mobile applications) we service, the impact of any such error, failure, vulnerability, or bug can be large in terms of absolute numbers of affected requests and customers.

Problems with our network or systems, or those of our vendors, contractors, or those with which we have strategic relationships, could result in actual or perceived breaches of our or our customers’ networks and systems or data. Actual or perceived breaches or other security incidents from these or other causes could lead to claims and litigation, indemnity obligations, regulatory audits, proceedings, and investigations and significant legal fees, significant costs for remediation, the expenditure of significant financial resources in efforts to analyze, correct, eliminate, remediate, or work around errors or defects, to address and eliminate vulnerabilities, and to address any applicable legal or contractual obligations relating to any actual or perceived security breach. They could damage our relationships with our existing customers and have a negative impact on our ability to attract and retain new customers. Because our business is focused on providing secure and high performing network services to our customers, we believe that our products and the networks and systems we use in our business could be targets for

~~Table of contents~~

hackers and others, and that an actual or perceived breach of, or security incident affecting, our networks, systems, or data, could be especially detrimental to our reputation, customer and channel partner confidence in our solution, and our business. Additionally, our products are designed to operate without interruption, including up to a 100% uptime guarantee for our Business and Enterprise plans. If a breach or security incident were to impact the availability of our network and products, our business, results of operations, and financial condition, as well as our reputation, could be adversely affected.

Any cybersecurity insurance that we carry may be insufficient to cover all liabilities incurred by us in connection with any privacy or cybersecurity incidents or may not cover the kinds of incidents for which we submit claims. For example, insurers may consider cyber attacks by a nation-state as an “act of war” and any associated damages as uninsured. We also cannot be certain that our insurance coverage will be adequate for data handling or data security liabilities actually incurred, that insurance will continue to be available to us on economically reasonable terms, or at all, or that any insurer will not deny coverage as to any future claim. The successful assertion of one or more large claims against us that exceed available insurance coverage, or the occurrence of changes in our insurance policies, including premium increases or the imposition of large deductible or co-insurance requirements, could have a material adverse effect on our business, results of operations, and financial condition, as well as our reputation.

If our global network that delivers our products or the core co-location facilities we use to operate our network are damaged, interfered with, or otherwise fail to meet the requirements of our business or local regulations, our ability to provide access to our network and products to our customers and maintain the performance of our network could be negatively impacted, which could cause our business, results of operations and financial condition to suffer.

As of ~~June~~September 30, 2021, we hosted our global network and served our customers from co-location and ISP-partner facilities located in more than ~~200~~250 cities and over 100 countries worldwide. In addition to these global facilities, much of the infrastructure for our global network and for our business and operations is maintained through a core co-location facility located in the U.S. Pacific Northwest, a second core co-location facility located in Luxembourg that provides certain redundancy to the U.S. core facility, and through a limited number of other U.S. co-location facilities that provide limited subsets of our network support. While we have electronic and, to a lesser extent, physical access to the components and infrastructure of our network and co-location facilities that are hosted by third parties—including ISP-partner facilities—we do not control the operation of these third-party facilities. Consequently, we may be subject to service disruptions as well as failures to provide adequate support for reasons that are outside of our direct control. Additionally, the demands placed on our global network by the COVID-19 pandemic ~~may~~are further ~~strain~~straining our network, which could lead to service disruptions. All of our co-location and ISP-partner facilities and network infrastructure are vulnerable to damage or interruption from a variety of sources including earthquakes; floods; fires; power loss; system failures; computer viruses; physical or electronic break-ins; human error; malfeasance; or interference, including by disgruntled employees, former employees, or contractors; terrorism; and other catastrophic events. For example, in April 2020, our core co-location facility in the U.S. Pacific Northwest experienced an outage of approximately 4-1/2 hours as a result of an error that occurred during planned maintenance activities at that facility and, during the outage, our customers lost access to certain features included in our products. Co-location facilities housing our network infrastructure may also be subject to local governmental or other administrative actions, changes to legal or permitting requirements, labor disputes, and litigation to stop, limit, or delay operations. Despite precautions taken at these facilities, such as disaster recovery and business continuity arrangements, the occurrence of a natural disaster or an act of terrorism, a decision to close the co-location facilities without adequate notice, or other unanticipated problems at these facilities could result in interruptions or delays in the availability of our network and products, impede our ability to scale our operations, or have other adverse impacts upon our business, results of operations, and financial condition. In addition, errors or defects in our customers’ software can result in unexpected and unintentional upward spikes in their usage of our

Table of contents

products and network, and those spikes can cause strains on, and adversely affect the availability and functioning of, our co-location facilities and our network.

The components of our global network are interrelated, such that disruptions or outages affecting one or more of our network co-location facilities may increase the strain on other components of our network. Concurrent disruptions or outages at a number of our network co-location facilities may lead to a cascading effect in which heightened strain on our network causes further disruptions or outages, particularly within the regions where the disruptions and outages occur. In addition, the failure of any of our core co-location facilities for any significant period of time, particularly our U.S. core co-location facility, could place a significant strain upon the ongoing operation of our business, as we have only limited redundant functionality for these facilities. Such a failure of a core co-location facility could degrade and slow down our network, reduce the functionality of our products for our customers, impact

~~Table of contents~~

our ability to bill our customers, and otherwise materially and adversely impact our business, reputation, and results of operations.

If our customers’ or channel partners’ access to our network and products is interrupted or delayed for any reason, our business could suffer.

Any interruption or delay in our customers’ or channel partners’ access to our network and products will negatively impact our customers. Our customers depend on the continuous availability of our network for the delivery and use of our products, and our products are designed to operate without interruption, including up to 100% uptime guarantee for our Business and Enterprise plans. If all or a portion of our network were to fail, our customers and partners could lose access to the Internet until such disruption is resolved or they deploy disaster recovery options that allow them to bypass our network. The adverse effects of any network interruptions on our reputation and financial condition may be heightened due to the nature of our business and our customers’ expectation of continuous and uninterrupted Internet access and low tolerance for interruptions of any duration. While we do not consider them to have been material, we have experienced, and may in the future experience, network disruptions and other performance problems due to a variety of factors. For example, in July 2019, we deployed an update to our web application firewall and certain aspects of the related software code resulted in excessive consumption of computing resources across our network, resulting in an outage on our network. In April 2020, our core co-location facility in the U.S. Pacific Northwest experienced an outage of approximately 4-1/2 hours as a result of an error that occurred during planned maintenance activities at that facility and, during the outage, our customers lost access to certain features included in our products. In addition, in July 2020, we experienced a configuration error in our backbone network that caused an outage for Internet properties and our products in certain areas lasting approximately 30 minutes.

The following factors, many of which are beyond our control, can affect the delivery, performance, and availability of our network and products:

•the development, maintenance, and functioning of the infrastructure of the Internet as a whole;

•the performance and availability of third-party telecommunications services with the necessary speed, data capacity, and security for providing reliable Internet access and services;

•decisions by the owners and operators of the co-location and ISP-partner facilities where our network infrastructure is deployed or by global telecommunications service provider partners who provide us with network bandwidth to terminate our contracts, discontinue services to us, shut down operations or facilities, increase prices, change service levels, limit bandwidth, declare bankruptcy, breach their contracts with us, or prioritize the traffic of other parties;

•the occurrence of earthquakes, floods, fires, power loss, system failures, physical or electronic break-ins, acts of war or terrorism, human error or interference (including by disgruntled employees, former employees, or contractors), and other catastrophic events;

•cyber attacks targeted at us, facilities where our network infrastructure is located, our global telecommunications service provider partners, or the infrastructure of the Internet;

•errors, defects, or performance problems in the software we use to operate our network and products and provide our related products to our customers;

•our customers’ or channel partners’ improper deployment or configuration of our customers' access to our network and products;

•the maintenance of the APIs in our systems that our partners use to interact with us;

Table of contents

•the failure of our redundancy systems, in the event of a service disruption at one of the facilities hosting our network infrastructure, to redistribute load to other components of our network; and

•the failure of our disaster recovery and business continuity arrangements.

The occurrence of any of these factors, or our inability to efficiently and cost-effectively fix such errors or other problems that may be identified, could damage our reputation, negatively impact our relationship with our customers, or otherwise materially harm our business, results of operations, and financial condition.

~~Table of contents~~

Detrimental changes in, or the termination of, any of our co-location relationships, ISP partnerships, or our other interconnection relationships with ISPs could adversely impact our business, results of operations, and financial condition.

Our relationships with ISP partners and other vendors that provide co-location services for our network infrastructure and the pricing and other material contract terms we have with these vendors are important for the maintenance, development, and expansion of our global network. If any of our co-location agreements were to expire or the pricing and other material terms of these agreements were to worsen, our business, results of operations, and financial condition would be adversely affected unless we were able to find a substitute vendor for the impacted facility on comparable or better terms. Moreover, a significant number of our important co-location agreements are with a single company and if our arrangements with this company were to change in a manner adverse to us, we could face difficulty in maintaining or growing our network on commercially viable terms. In addition, as part of our arrangements with some of our ISP partners, the ISP partner has agreed to host our equipment for free or at a discount to the partner’s customary rate. There can be no assurances that these ISP partners will continue to provide these types of favorable equipment hosting arrangements in the future.

The efficient and effective operation of our network also relies upon a series of mutually beneficial arrangements with other Internet infrastructure companies. These arrangements are often referred to as “peering” or “interconnection” agreements, and allow us and our ISP partners to reduce bandwidth costs related to operating our respective networks. If the underlying competitive, business, or operational incentives supporting these arrangements were to change, we or our partners might terminate these agreements or allow them to expire. Many of our peering or interconnection agreements have a term of three years or less, after which such agreements auto-renew on an annual basis. Changes to the underlying incentive structure of peering arrangements may result from parties seeking to take advantage of an essential position or enter into exclusive arrangements, changes to U.S. or international laws, regulations, policies, or changes in the norms governing the relationships among Internet infrastructure providers. Without favorable peering arrangements, we would incur significantly increased costs to continue to provide our products at their current levels and such increased costs could adversely impact our business, results of operations, and financial condition. To the extent that additional countries begin to regulate peering with outside networks, our costs may increase and our business and results of operations could be adversely impacted.

If our network and products do not interoperate with our customers’ internal networks and infrastructure or with third-party products, websites, or services, our network may become less competitive and our results of operations may be harmed.

Our network and products must interoperate with our customers’ existing internal networks and infrastructure. These complex internal systems are developed, delivered, and maintained by the customer and a myriad of vendors and service providers. As a result, the components of our customers’ infrastructure have different specifications, rapidly evolve, utilize multiple protocol standards, include multiple versions and generations of products, and may be highly customized. We must be able to interoperate and provide products to customers with highly complex and customized internal networks, which requires careful planning and execution between our customers, our customer support teams and, in some cases, our channel partners. Further, when new or updated elements of our customers’ infrastructure or new industry standards or protocols are introduced, we may have to update or enhance our network to allow us to continue to provide our products to customers. Our competitors or other vendors may refuse to work with us to allow their products to interoperate with our network and products, which could make it difficult for our network and products to function properly in customer internal networks and infrastructures that include these third-party products.

We may not deliver or maintain interoperability quickly or cost-effectively, or at all. These efforts require capital investment and engineering resources. If we fail to maintain compatibility of our network and products with our customers’ internal networks and infrastructures, our customers may not be able to fully utilize our network and

Table of contents

products, and we may, among other consequences, lose or fail to increase our market share and number of customers and experience reduced demand for our products, which would materially harm our business, results of operations, and financial condition.

Because we provide some of our products through a reverse-proxy, which is a network arrangement in which Internet user requests initially are directed to our network’s servers rather than those of our customers, the source of some traffic may be difficult to ascertain. When they cannot identify the source of the traffic, some governments, third-party products, websites, or services may block our traffic or blacklist our IP addresses. If our customers

~~Table of contents~~

experience significant instances of traffic blockages, they will experience reduced functionality or other inefficiencies, which would reduce customer satisfaction with our network and products and likelihood of renewal.

We rely on a limited number of suppliers for certain components of the equipment we use to operate our network and any disruption in the availability of these components could delay our ability to expand or increase the capacity of our global network or replace defective equipment.

We rely on a limited number of suppliers for several components of the equipment we use to operate our network and provide products to our customers. Our reliance on these suppliers exposes us to risks, including reduced control over production costs and constraints based on the then current availability, terms, and pricing of these components. For example, we generally rely on a single source to purchase the servers that we use in our network and we ordinarily purchase these components on a purchase-order basis, without any long-term contracts guaranteeing supply. While the network equipment and servers we purchase generally are commodity equipment and we believe an alternative supply source for servers on substantially similar terms could be identified quickly, our business could be adversely affected until those efforts were completed. In addition, the technology equipment industry has experienced component shortages and delivery delays in the past, and we may experience shortages or delays, including as a result of natural disasters, increased demand in the industry, or our suppliers lacking sufficient rights to supply the components in all jurisdictions in which we have co-location facilities that support our global network. For example, the ongoing COVID-19 pandemic and supply chain constraints for CPUs, RAM, SSDs, and other electronics has resulted, and we expect will continue to result in disruptions and delays for these components and the delivery and installation of such components at our co-location facilities. In addition, starting during the first quarter of 2021 and continuing inthrough the ~~second~~third quarter, a global shortage of microchips has resulted in supply constraints for a number of electronics firms, including manufacturers of servers, and the duration and ultimate severity of this ongoing shortage is uncertain. If our supply of certain components is disrupted or delayed, there can be no assurance that additional supplies or components can serve as adequate replacements for the existing components or that supplies will be available on terms that are favorable to us, if at all. Any disruption or delay in the supply of our hardware components may delay the opening of new co-location facilities, limit capacity expansion or replacement of defective or obsolete equipment at existing co-location facilities, or cause other constraints on our operations that could damage our customer relationships.

The actual or perceived failure of our products to block malware or prevent a security breach could harm our reputation and adversely impact our business, results of operations, and financial condition.

Our security products are designed to reduce the threat to our customers posed by malware and other Internet security threats. Our security products may fail to detect or prevent malware or security breaches for any number of reasons. Even where our security products perform as intended, the performance of our security products can be negatively impacted by our failure to enhance, expand, or update our network and products; improper classification of websites by our employees, automated systems, and partners which identify and track malicious websites; improper deployment or configuration of our products; and many other factors.

Companies are increasingly subject to a wide variety of attacks on their networks and systems, including traditional computer hackers; malicious code, such as viruses and worms; distributed denial-of-service attacks; sophisticated attacks conducted or sponsored by nation-states; advanced persistent threat intrusions; ransomware; phishing attacks and other forms of social engineering; employee, vendor, or contractor errors or malfeasance; and theft or misuse of intellectual property or business or personal data, including by disgruntled employees, former employees, or contractors. No security solution, including our products, can address all possible security threats or block all methods of penetrating a network or otherwise perpetrating a security incident. Accordingly, our security products may be unable to detect or prevent a threat until after our customers are impacted. As our products are adopted by an increasing number of enterprises, it is possible that the individuals and organizations behind cyber threats will focus on identifying ways to circumvent or defeat our security products. If our network is targeted by attacks specifically designed to disrupt it, it could create the perception that our security products are not capable of

Table of contents

providing adequate security. As a provider of security products, any perceived lack of security to our network or any of our products could erode our customers’ and potential customers’ trust in our network and products. Moreover, a high-profile security breach of another cloud services provider could cause our customers and potential customers to lose trust in cloud solutions generally, and cloud-based products like ours in particular. Any such loss of trust could materially and adversely impact our ability to retain existing customers or attract new customers.

Our customers must rely on complex network and security infrastructures, which include products and services from multiple vendors, to secure their networks. If any of our customers becomes infected with malware, or experiences a security breach, they could be disappointed with our products, regardless of whether our security products are

~~Table of contents~~

intended to block the attack or would have blocked the attack if the customer had properly configured our products or their network, or taken other steps within their control. For example, in April 2017, we published details of a web cache deception attack method that exploits the misconfiguration of websites to circumvent reverse-proxy systems such as ours. While the vulnerability associated with this attack method relates to misconfiguration of websites outside of our control, a customer experiencing a security event related to this vulnerability may nevertheless blame us or become dissatisfied with our products as a result. Additionally, if any enterprises that are publicly known to use our network and products are the subject of a cyber attack that becomes publicized, this could harm our reputation and our current or potential customers may look to our competitors for alternatives to our network and products.

From time to time, industry or financial analysts and research firms test our network and related security products against other security products. Our products may fail to detect or prevent threats in any particular test for a number of reasons, including misconfiguration. To the extent potential customers, industry or financial analysts, or testing firms believe that the occurrence of a failure to detect or prevent any particular threat is a flaw or indicates that our products do not provide significant value or provide less value than competitive solutions, our reputation and business could be materially harmed.

Any real or perceived flaws in our network, or any actual or perceived security breaches of our customers, could result in:

•a loss of existing or potential customers or channel partners;

•delayed or lost sales and harm to our financial condition and results of operations;

•a delay in attaining, or the failure to attain, market acceptance of our products;

•the expenditure of significant financial resources in efforts to analyze, correct, eliminate, remediate, or work around errors or defects, to address and eliminate vulnerabilities, and to address any applicable legal or contractual obligations relating to any actual or perceived security breach;

•negative publicity and damage to our reputation and brand; and

•legal claims and demands (including for stolen assets or information, repair of system damages, and compensation to customers and business partners), litigation, regulatory audits, proceedings or investigations, and other liability.

Any of the above results could materially and adversely affect our business, results of operations, and financial condition.

Abuse, misuse, or ~~misuse~~other unauthorized use of our internal network services tools could cause significant harm to our business and reputation.

In order to provide real-time support to our customers, we have created internal network services tools that are used by our employees to diagnose and correct customer security, performance, and reliability issues. If our employees were to intentionally abuse these tools by interfering with or altering our customers’ Internet properties, our customers could be significantly harmed. Similarly, our customers could be harmed if government personnel in any countries in which our employees operate were to pressure our employees to use these tools to interfere with or alter our customers’ Internet properties. Our employees’ inadvertent misuse of these tools could similarly harm our customers. For example, third parties have in the past attempted to induce our employees to use their administrative access to reveal, remove, or disable our customers’ information and content, including by submitting fraudulent law enforcement requests, copyright takedown requests, or other content-based complaints. Any such improper disclosure or removal could significantly and adversely impact our business and reputation. While our tools have been developed only for authorized use by our employees, any unauthorized release of these tools to third parties would represent a significant vulnerability in our products. Accordingly, any abuse or misuse of our

Table of contents

network services tools could significantly harm our business and reputation. If it became necessary to further restrict the availability or use of our network services tools by our employees in response to any abuse or misuse, our ability to deliver high-quality and timely customer support could be harmed.

We may choose to make public disclosures ~~of negative events~~in press releases, on our website and blog, through social media, and in other ways about our network, systems, products, and ~~products~~technology, which may include negative events, when we are not otherwise required by applicable law and those disclosures could materially and adversely impact our business, reputation, and results of operations.

In the past we have been, and in the future we expect to be, transparent about our network, systems, products, and ~~products~~technology with our customers and the public in general. We believe that being rigorously and promptly transparent is an essential part of maintaining trust with our customers. At times, this transparency may result in us publicly disclosing

~~Table of contents~~

information, ~~regarding~~including negative events, about our network, systems, products, and ~~products~~technology in circumstances where we may not be required to do so by applicable law. If and when we choose to make these types of non-legally required public disclosures, we may suffer reputational damage, loss of business, litigation, indemnity obligations, damages for contract breach, penalties for violation of applicable laws or regulations, significant costs for remediation, and other liabilities that could materially and adversely impact our business, reputation, and results of operations.

We provide service level commitments under our Enterprise plan customer contracts and our Business plan terms of service. If we fail to meet these contractual commitments, we could be obligated to provide credits for future service or allow customers to terminate their subscriptions and our business could suffer.

Our Enterprise plan agreements and our Business plan terms of service typically provide for service level commitments, which contain specifications regarding the availability and performance of our network. In particular, our Enterprise plan subscriptions and our Business plan terms of service include up to a 100% uptime guarantee. Any failure of or disruption to our infrastructure could adversely impact the security, performance, and reliability of our network and products for our customers. If we are unable to meet our stated service level commitments or if we suffer extended periods of poor performance or unavailability of our network and products, these customers could seek to bring claims against us or terminate their agreements with us and, in the case of our contracted customers, we may be contractually obligated to provide affected customers with service credits that they may apply against future subscription fees otherwise owed to us, and, in certain cases, refunds of pre-paid and other fees. For example, the June 2019 route leak and July 2019, April 2020, and July 2020 outages triggered certain of these types of obligations. The impact of the June 2019 route leak and the July 2019, April 2020, and July 2020 outages did not have a material impact on our results of operations or financial condition; however, other future events like these may materially and adversely impact our results of operations or financial condition. Our revenue, other results of operations, and financial condition could be harmed if we suffer performance issues or downtime that exceeds the service level commitments under our agreements and terms of service with our paying customers.

If our products do not obtain and maintain market acceptance, our ability to grow our business and our results of operations may be adversely affected.

Our products are still evolving and it is difficult to predict customer demand and adoption rates for our product offerings. We believe that our network and cloud-based products represent a major shift from traditional solutions. Many of our potential customers, particularly large enterprises and government entities, face barriers to adopting our offerings because of their prior investment in, and the familiarity of their IT personnel with, on-premises, appliance-based solutions. As a result, our sales process often involves extensive efforts to educate our customers about our products, particularly as we continue to pursue customer relationships with large organizations. Our customers also expect us to meet voluntary certifications or adhere to standards established by third parties and may demand that they be provided a report from our auditors that we are in compliance. Although we currently have certain certifications such as SOC2 Type 1 and Type 2, SOC3, PCI DSS, ISO 27001, and ISO 27701, we may not be successful in continuing to maintain those certifications or in obtaining other certifications. In addition, sales to government entities and other large enterprises may in particular be conditioned upon adherence to the FedRAMP and Electronic Identification and Trust Services Regulation standards in the United States and the EU, respectively, and we do not currently have these certifications. The costs of obtaining and maintaining certification pursuant to any of these standards are significant, and any failure to obtain and maintain such certifications for our network and products could reduce demand for them, which would harm our business, results of operations, and financial condition. To the extent our competitors have, and we do not have, these certifications, we may lose the opportunity to obtain subscriptions from certain potential paying customers.

Table of contents

Despite our efforts, we can provide no assurance that our cloud-based products will obtain market acceptance or that competing products or services based on other cloud-based and/or on-premises technologies will not achieve market acceptance. If we fail to achieve market acceptance of our products or are unable to keep pace with industry changes or obtain necessary product certifications, our ability to grow our business, results of operations, and financial condition will be materially and adversely affected.

We may not be able to respond to rapid technological changes or develop new products and features that are attractive to our current and prospective future customers.

The industry in which we compete is characterized by rapid technological change, including frequent introductions of new products and services, evolving industry standards, changing regulations, and the development of novel cyber attacks by hostile parties, as well as changing customer needs, requirements, and preferences. Our need for

~~Table of contents~~

continuous innovation is driven not only by competitive forces within our industry but also by our need to out-innovate the highly motivated third parties seeking to breach or compromise our network and those of our customers for economic, political, military, or other purposes.

Our ability to attract new customers and increase revenue from existing customers will depend in significant part on our ability to anticipate and respond effectively to these forces on a timely basis and continue to introduce enhancements to our network and develop new products. If new technologies emerge that deliver competitive products and services at lower prices, more efficiently, more conveniently, more securely or reliably, or are higher performing, these technologies could render our network and existing products less attractive to our current and prospective future customers, or obsolete. The development of novel attacks or exploits by criminal or malicious elements or hostile state actors also could render our network and existing products less effective or obsolete. The success of our business depends on our continued investment in our research and development organization to increase the integrity, reliability, availability, and scalability of our products. We may experience difficulties with development, design, or marketing of such enhancements to our network and products that could delay or prevent their development, introduction, or implementation. We have in the past experienced delays in the planned expansion of our network and in our internally planned or publicly announced release dates of new products and new features and capabilities, and there can be no assurance that planned expansions of our network will occur on schedule and that new products, features, or capabilities will be released according to schedule. Any delays could result in adverse publicity, loss of revenue or market acceptance, or claims by customers brought against us, all of which could have a material and adverse effect on our reputation, business, results of operations, and financial condition.

Risks Related to Legal, Tax, and Regulatory Matters

Activities of our paying and free customers or the content of their websites and other Internet properties may violate applicable laws and/or our terms of service and could subject us to lawsuits, regulatory enforcement actions, and/or liability in various jurisdictions.

Through our network, we provide a wide variety of products that enable our customers to exchange information, conduct business, and engage in various online activities both domestically and internationally. Our customers may use our network and products in violation of applicable law or in violation of our terms of service or the customer’s own policies. The existing laws relating to the liability of providers of online products and services for activities of their users are highly unsettled and in flux both within the United States and internationally. We are currently and, in the future, may be subject to lawsuits and/or liability arising from the conduct of our customers. Additionally, the conduct of our customers may subject us to regulatory enforcement actions and/or liability. We are a defendant in lawsuits, both in the United States and abroad, seeking injunctive relief and/or damages against us based on content that is made available through our customers’ websites. A number of these lawsuits involve copyright infringement claims, and courts in Italy and Germany ~~recently disagreed with our position and~~have at times directed us to take action by removing access to content of certain sites on our network. There can be no assurance that we will not face similar litigation in the future or that we will prevail in any litigation we are facing or may face. An adverse decision in one or more of these lawsuits could materially and adversely affect our business, results of operations, and financial condition.

Several U.S. federal statutes may apply to us with respect to various activities of our customers, including: the Digital Millennium Copyright Act (the DMCA), which provides recourse for owners of copyrighted material who believe their rights under U.S. copyright law have been infringed on the Internet; and section 230 of the Communications Decency Act (the CDA), which addresses blocking and screening of content on the Internet.

Table of contents

Although these and other similar legal provisions ~~such as the European Union (the EU) e-Commerce Directive,~~ provide limited protections from liability for service providers like us, those protections may not be interpreted in a way that applies to us, may be amended in the future, or may not provide us with complete protection from liability claims. If we are found not to be protected by the safe harbor provisions of the DMCA, CDA or other similar laws, or if we are deemed subject to laws in other countries that may not have the same protections or that may impose more onerous obligations on us, we may owe substantial damages and our brand, reputation, and financial results may be harmed.

Current and future litigation subjects us to claims for very large potential damages based on a significant number of online occurrences under statutory or other damage theories. Such claims may result in liability that exceeds our ability to pay or our insurance coverage. Even if claims against us are ultimately unsuccessful, defending against

~~Table of contents~~

such claims will increase our legal expenses and divert management’s attention from the operation of our business, which could materially and adversely impact our business and results of operations.

Policies and laws in this area remain highly dynamic, and we may face additional theories of intermediary liability in various jurisdictions. Many policymakers in the United States have called for a re-examination of CDA section 230 and the EU is considering a new Digital Services Act and Digital Markets Act to update the rules governing digital services like ours, including replacing the eCommerce directive and imposing additional legal requirements on service providers. In addition, in 2019, the EU approved a copyright directive that will impose additional obligations on service providers and failure to comply could give rise to significant liability. Other laws and pending legislation at the EU level (terrorist content), in ~~Germany (extremist content),~~the United Kingdom (online harms), Australia ~~(violent content)~~(online harms), and ~~Singapore (online falsehoods)~~India (Information Technology Rules), as well as other new laws like them, may also expose Internet companies like us to significant liability. We may incur additional costs to comply with these new laws, which may have an adverse effect on our business, results of operations, and financial condition.

Our policies regarding user privacy could cause us to experience adverse business and reputational consequences with customers, employees, suppliers, government entities, and other third parties.

As a company, we strive to protect our customers’ privacy consistent with applicable law. Consequently, we generally do not provide personal information about our customers without legal process. In accordance with our contractual commitments to our customers, we may need to challenge legal process requesting disclosure of personal information where such requests are inconsistent with applicable data protection laws. In addition, from time to time, government entities may seek our assistance with obtaining information about our customers or could request that we modify our network and products in a manner to permit access or monitoring. In light of our privacy commitments, we may legally challenge law enforcement requests to provide a feed of content transiting our network, to obtain encryption keys, or to modify or weaken encryption. We may face complaints from individuals who assert we have provided their information improperly to law enforcement or in response to third-party abuse complaints, despite policies we have in place to protect that information. To the extent that we do not provide assistance to or comply with requests from government entities or challenge those requests publicly or in court, we may experience adverse political, business, and reputational consequences. We may also face such adverse political, business, and reputational consequences to the extent that we provide, or are perceived as providing, assistance to government entities that exceeds our legal obligations. For example, we periodically receive requests for information purportedly originating from law enforcement agencies or pursuant to legal process, but which are fraudulent or improper attempts to cause us to reveal customer information. Any such disclosure could significantly and adversely impact our business and reputation.

We publish a transparency report on a semi-annual basis to provide details of law enforcement and government requests we receive. Our transparency report also includes a list of certain actions we have not taken in response to law enforcement requests. If we are ever required by law enforcement to take one or more of the actions covered by those disclosures, then we would have to remove the applicable disclosures from our transparency report. Both the publishing of our transparency report and, conversely, the potential narrowing of the list of actions we have not taken in response to law enforcement requests could damage our business and reputation.

Our business could be adversely impacted by changes in Internet access for our customers as a result of competitive behavior or laws specifically governing the Internet.

Our network performance and reliability depends on the quality of our customers’ access to the Internet. Certain features of our network require significant bandwidth and fidelity to work effectively. Internet access is frequently provided by companies that have significant market power that could take actions that degrade, disrupt, or increase the cost of user access to our network, which would negatively impact our business. We could incur greater

Table of contents

operating expenses and our customer acquisition and retention could be negatively impacted if other network operators:

•implement usage-based pricing;

•discount pricing for competitive products;

•otherwise materially change their pricing rates or schemes;

•charge us to deliver our traffic at certain levels or at all;

•throttle traffic based on its source or type;

•implement bandwidth caps or other usage restrictions; or

~~Table of contents~~

•otherwise try to monetize or control access to their networks.

In addition, there are various laws and regulations that could impede the growth of the Internet or online services, and new laws and regulations may be adopted in the future. These laws and regulations could involve interconnection and network management; taxation; tariffs; privacy; data protection; content; copyrights; distribution; electronic contracts and other communications; consumer protection; and requirements for the characteristics and quality of services, any of which could decrease the demand for, or the usage of, our products. Legislators and regulators may make legal and regulatory changes, or interpret and apply existing laws, in ways that require us to incur substantial costs, expose us to unanticipated civil or criminal liability, or cause us to change our business practices. If these changes are implemented, it could have an adverse and negative impact on our business. In addition, we may be banned from providing our products in certain countries, which would prevent our ability to grow our business in such markets and would also have a detrimental impact on the performance and scope of our network. These changes or increased costs could materially harm our business, results of operations, and financial condition.

Failure to comply with laws and regulations applicable to our business could subject us to fines and penalties and could also cause us to lose customers or otherwise harm our business.

Our business is subject to regulation by various federal, state, local, and foreign governmental agencies, including agencies responsible for monitoring and enforcing compliance with various legal obligations, such as privacy and data protection laws and regulations, intellectual property laws, employment and labor laws, workplace safety, environmental laws, consumer protection laws, anti-bribery laws, governmental trade sanctions laws, import and export controls, anti-corruption and anti-bribery laws, federal securities laws, and tax laws and regulations. In certain jurisdictions, these regulatory requirements may be more stringent than in the United States. These laws and regulations impose added costs on our business. Noncompliance with applicable regulations or requirements could subject us to:

•investigations, enforcement actions, and sanctions;

•mandatory changes to our network and products;

•disgorgement of profits, fines, and damages;

•civil and criminal penalties or injunctions;

•claims for damages by our customers or channel partners;

•termination of contracts;

•loss of intellectual property rights; and

•temporary or permanent debarment from sales to government organizations.

If any governmental sanctions are imposed, or if we do not prevail in any possible civil or criminal litigation, our business, results of operations, and financial condition could be adversely affected. In addition, responding to any action will likely result in a significant diversion of our management’s attention and resources and an increase in professional fees. Enforcement actions and sanctions could materially harm our business, results of operations, and financial condition.

Additionally, companies in the technology industry have recently experienced increased regulatory scrutiny. Any reviews by regulatory agencies or legislatures may result in substantial regulatory fines, changes to our business practices, and other penalties, which could negatively affect our business and results of operations. Changes in

Table of contents

social, political, and regulatory conditions or in laws and policies governing a wide range of topics may cause us to change our business practices. Further, our expansion into a variety of new fields also could raise a number of new regulatory issues. These factors could negatively affect our business and results of operations in material ways.

Our actual or perceived failure to comply with privacy, data protection, and information security laws, regulations, and obligations could harm our business.

We receive, store, use, and otherwise process personal information and other information relating to individuals. There are numerous federal, state, local, and international laws and regulations regarding privacy, data protection, information security, and the storing, sharing, use, processing, transfer, disclosure, and protection of personal information and other content, the scope of which are changing, subject to differing interpretations, and may be

~~Table of contents~~

inconsistent among jurisdictions, or conflict with other rules. These data protection and privacy-related laws and regulations are evolving and may result in ever-increasing regulatory and public scrutiny and escalating levels of enforcement and sanctions. For example, the EU’s General Data Protection Regulation (the GDPR), in effect since May 25, 2018, imposes more stringent data protection requirements than previous EU data protection laws and provides for penalties for noncompliance of up to the greater of €20 million or four percent of worldwide annual revenues. In addition, the Court of Justice of the European Union (CJEU) invalidated the U.S.-EU Privacy Shield in July 2020 in the "Schrems II" case. The GDPR requires that certain mechanisms must be in place in order for the personal data of EU residents to be transferred to the United States for processing. The U.S.-EU Privacy Shield was one such mechanism. The CJEU’s decision in Schrems II also called into question the validity of the EU Standard Contractual Clauses ~~(SCCs)~~(EU SCCs) — the other widely used mechanism for transferring data to the United States. The CJEU opinion found that while the EU SCCs remain a valid basis for transfer, a data processor must also have in place additional safeguards sufficient in the controller’s view to provide GDPR-level protection for EU personal data against U.S. government’s laws and practices for accessing personal data transferred to the United States.

The CJEU decision created regulatory uncertainty that has been compounded by varying interpretations of the decision by independent data protection regulators throughout Europe. On April 27, 2021, the Portuguese data protection authority, Comissão Nacional de Protecção de Dados (CNPD), issued an opinion directing the Portuguese National Statistics Institute, I.P. (INE) to discontinue use of our services based on the GDPR. Further application of similar decisions by the CNPD or other data protection authorities may interfere with our ability to provide services to existing customers or to acquire new customers. In June 2021, the European Commission published new EU SCCs and the European Data Protection Board (EDPB) adopted final recommendations on cross-border data transfers in light of the Schrems II case. The new EU SCCs and EDPB guidance provide clarity on cross-border data transfers, but individual European data protection regulatory authorities may differ in their interpretation and enforcement of the EDPB’s guidance. Implementing the new EU SCCs and EDPB guidance may result in substantial costs, require changes to our business practices, limit our ability to provide certain products in certain jurisdictions, limit our ability to provide certain products to certain customers, or materially adversely affect our business and operating results.

Additionally, Brexit has created additional uncertainty with regard to the regulation of data protection in the United Kingdom. ~~In particular, although the~~The United Kingdom has enacted legislation that is substantially consistent with the GDPR (with penalties for noncompliance of up to the greater of four percent of global revenues or £17.5 million)~~, a final~~ and the European Commission formally adopted an adequacy decision ~~has not been issued~~under GDPR to ~~allow~~provide for ~~long-term~~the free flow of personal data between the EU and the United Kingdom. ~~The European Commission and~~However, the ~~United Kingdom government announced a Trade and Cooperation Agreement on December 24, 2020, providing for a temporary free flow~~adequacy decision sunsets in 2025. In light of ~~personal~~the rapidly changing data ~~between the EU and~~protection landscape in the United Kingdom and ~~while~~ the ~~European Commission issued a draft~~EU, it is not guaranteed that this adequacy decision ~~in February 2021 that would grant the United Kingdom adequacy status, that decision has not yet been formally adopted.~~will be renewed. As a result, it remains to be seen ~~how Brexit will impact the manner in which United Kingdom data protection laws or regulations will develop and~~ how data transfers to and from the United Kingdom will be regulated and enforced in the longer term. Further, the United Kingdom has opened a consultation on new UK standard contractual clauses (UK SCCs) that are likely to differ from the newly adopted EU SCCs. When the new UK SCCs are adopted, we will need to ensure the correct agreements are in place for data flows to and from the UK as well as the EU, which may result in substantial costs, require changes to our business practices, limit our ability to provide certain products in certain jurisdictions, limit our ability to provide certain products to certain customers, or materially adversely affect our business and operating results.

We also expect that there will continue to be new laws, regulations, and industry standards concerning privacy, data protection, and information security proposed and enacted in various jurisdictions. For example, in the United States, various laws and regulations apply to the collection, processing, disclosure and security of certain types of data, including the Electronic Communications Privacy Act, the Computer Fraud and Abuse Act, the Health Insurance Portability and Accountability Act of 1996, the Gramm-Leach-Bliley Act, and state laws relating to privacy and data security. There are also a number of proposed U.S. federal and state privacy and data protection bills under consideration in Congress and state legislatures across the country.

Table of contents

The California Consumer Privacy Act (the CCPA) went into effect on January 1, 2020 and accompanying regulations were issued by the California Office of the Attorney General in June 2020. Among other things, the CCPA requires covered companies to provide new disclosures to California consumers and afford such consumers new abilities to access and delete their personal information, and to opt-out of certain sales of personal information. On November 3, 2020, California voters approved the California Privacy Rights and Enforcement Act (the CPRA), which is expected to go into effect on January 1, 2023. The CPRA significantly modifies the CCPA and further aligns California privacy laws with the GDPR. The approval of the CPRA introduces additional uncertainty to the California privacy landscape as the California legislature will be required to reconcile the CCPA with the CPRA, and the California Office of the Attorney General will need to provide additional regulatory guidance, as well as create a new data protection regulatory body, all of which will likely result in us incurring additional costs and expenses in an effort to comply with the evolving requirements. Additional states in which we operate have recently enacted, or may in the future enact, similar privacy legislation.

The number of data protection laws globally is rising as well. More countries, including India, Australia, New Zealand, Singapore, and Japan are exploring new or updated comprehensive data protection regimes. For

~~Table of contents~~

example, Brazil’s comprehensive data protection law, the Lei Geral de Proteção de Dados (the LGPD), went into effect in 2020 and contains requirements for contractual guarantees that need to be in place for personal data to be processed outside Brazil and penalties may result in fines of up to 2% of the organization’s Brazilian revenue for the prior year, up to a total of 50 million reais (or approximately $9.3 million USD) per violation. In ~~China, we~~addition, on August 20, 2021, the Standing Committee of China’s National People’s Congress promulgated China’s Personal Information Protection Law (PIPL), which will take effect November 1, 2021, and includes potential fines for violations of up to 50 million RMB or 5% of an organization’s annual revenue for the prior financial year. We will continue to monitor ~~legal and government advisory developments regarding the Chinese Cybersecurity Law and Draft Cybersecurity Review Measures~~all laws for impacts to our business related to cross-border data transfer limitations and evolving privacy, security, or data protection requirements. ~~In addition, some~~Some countries are also considering or have enacted legislation requiring local storage and processing of data that could increase the cost and complexity of delivering our services.

We will need to closely monitor developments, including enforcement actions or private litigation under the LGPD, the CCPA, PIPL, and other laws to determine if we will need to modify our data processing practices and policies, which may result in us incurring additional costs and expenses in an effort to comply.

We are also subject to the terms of our privacy policies and contractual obligations to third parties related to privacy, data protection, and information security. We strive to comply with applicable laws, regulations, policies, and other legal obligations relating to privacy, data protection, and information security to the extent possible. However, the regulatory framework for privacy and data protection worldwide is evolving rapidly, and it is possible that these or other actual or alleged obligations may be interpreted and applied in a manner that is inconsistent from one jurisdiction to another and may conflict with other rules or our practices.

Any failure or perceived failure by us to comply with our privacy policies, our privacy-related obligations to customers or other third parties, applicable laws or regulations, or any of our other legal obligations relating to privacy, data protection, or information security may result in governmental investigations or enforcement actions, litigation, claims, or public statements against us by consumer advocacy groups or others and could result in significant liability or cause our customers to lose trust in us, which could cause them to cease or reduce use of our products and otherwise have an adverse effect on our reputation and business. Furthermore, the costs of compliance with, and other burdens imposed by, the laws, regulations, and policies that are applicable to the businesses of our customers may limit the adoption and use of, and reduce the overall demand for, our products.

Additionally, if third parties we work with, such as sub-processors, vendors, or developers, violate applicable laws or regulations, contractual obligations, or our policies—or if it is perceived that such violations have occurred—such actual or perceived violations may also have an adverse effect on our business. Further, any significant change to applicable laws, regulations, or industry practices regarding the collection, use, retention, security, disclosure, or other processing of users’ content, or regarding the manner in which the express or implied consent of users for the collection, use, retention, disclosure, or other processing of such content is obtained, could increase our costs and require us to modify our network, products, and features, possibly in a material manner, which we may be unable to complete, and may limit our ability to store and process customer data or develop new products and features.

We are subject to anti-corruption, anti-bribery, and similar laws, and noncompliance with such laws can subject us to criminal penalties or significant fines and harm our business and reputation.

We are subject to the U.S. Foreign Corrupt Practices Act of 1977, the UK Bribery Act 2010, and other anti-corruption, anti-bribery, anti-money laundering, and similar laws in the United States and other countries in which we conduct activities. Anti-corruption and anti-bribery laws, which have been enforced aggressively and are interpreted broadly, prohibit companies and their employees and agents from promising, authorizing, making, or

Table of contents

offering improper payments or other benefits to government officials and others in the public sector. We leverage third parties, including channel partners, to sell subscriptions to our products, host many of our co-location facilities for our network, and conduct our business abroad. We and these third parties may have direct or indirect interactions with officials and employees of government agencies or state-owned or affiliated entities and we may be held liable for the corrupt or other illegal activities of our business partners and intermediaries, our employees, representatives, contractors, channel partners and agents, even if we do not explicitly authorize such activities. Further, some of our international sales activity occurs, and some of our network infrastructure is located, in parts of the world that are recognized as having a greater potential for business practices that violate anti-corruption, anti-bribery, or similar laws.

We cannot assure you that all of our employees and agents have complied with, or in the future will comply with, our policies and applicable law. As we continue to increase our international sales and business and expand our network globally, our risks under these laws may increase. The investigation of possible violations of these laws, including internal investigations and compliance reviews that we may conduct from time to time, could have a

~~Table of contents~~

material adverse effect on our business. Noncompliance with these laws could subject us to investigations, severe criminal or civil sanctions, settlements, prosecution, loss of export privileges, suspension or debarment from U.S. government contracts and other contracts, other enforcement actions, the appointment of a monitor, disgorgement of profits, significant fines, damages, other civil and criminal penalties or injunctions, whistleblower complaints, adverse media coverage and other consequences. Other internal and government investigations, regulatory proceedings, or litigation, including private litigation filed by our stockholders, may also follow as a consequence. Any investigations, actions, or sanctions could materially harm our reputation, business, results of operations, and financial condition. Further, the promulgation of new laws, rules or regulations or new interpretations of current laws, rules or regulations could impact the way the we do business in other countries, including requiring us to change certain aspects of our business to ensure compliance, which could reduce revenue, increase costs, or subject us to additional liabilities.

We may face fines, penalties, or other costs, either directly or vicariously, if any of our partners, resellers, contractors, vendors or other third parties fail to adhere to their compliance obligations under our policies and applicable law.

We use a number of third parties to perform services or act on our behalf in areas like sales, network infrastructure, administration, research, and marketing. It may be the case that one or more of those third parties fail to adhere to our policies or violate applicable federal, state, local, and international laws, including but not limited to, those related to corruption, bribery, economic sanctions, and export/import controls. Despite the significant challenges in asserting and maintaining control and compliance by these third parties, we may be held fully liable for third parties’ actions as fully as if they were a direct employee of ours. Such liabilities may create harm to our reputation, inhibit our plans for expansion, or lead to extensive liability either to private parties or government regulators, which could adversely impact our business, results of operations, and financial condition.

We may have exposure to greater than anticipated income tax liabilities and may be affected by changes in tax laws, which could adversely impact our results of operations.

We operate in a number of tax jurisdictions globally, including in the United States at the federal, state, and local levels, and in many other countries, and plan to continue to expand the scale of our operations in the future. Accordingly, we are subject to income taxes in the United States and various jurisdictions outside of the United States. While to date we have not incurred significant income taxes in operating our business, we may in the future face significant tax liabilities. Our tax expense could also be impacted by changes in non-deductible expenses, changes in excess tax benefits from stock-based compensation, changes in the valuation of deferred tax assets and liabilities and our ability to utilize them, the applicability of withholding taxes, and effects from acquisitions.

Our tax provision could also be impacted by changes in accounting principles, changes in U.S. federal, state, or international tax laws applicable to corporate multinationals such as the recent legislation enacted in the United States, other fundamental law changes currently being considered by many countries, and changes in taxing jurisdictions’ administrative interpretations, decisions, policies, and positions. For example, on December 22, 2017, tax reform legislation referred to as the Tax Cuts and Jobs Act (the Tax Act) was enacted in the United States. The Tax Act significantly revises U.S. federal income tax law, including lowering the corporate income tax rate to 21%, requiring companies to pay a one-time transition tax on certain unrepatriated earnings of foreign subsidiaries, implementing a modified territorial tax system, requiring a current inclusion in U.S. federal taxable income of certain earnings of controlled foreign corporations, and creating a base erosion anti-abuse tax.

Table of contents

Additionally, in October 2015, the Organisation for Economic Co-Operation and Development (the OECD) released final guidance covering various topics, including transfer pricing, country-by-country reporting, and definitional changes to permanent establishment that could ultimately impact our tax liabilities. In March 2018, the European Commission released a proposal for a European Council directive on taxation of specified digital services. The proposal calls for an interim tax on certain revenues from digital activities, as well as a longer-term regime that creates a taxable presence for digital services and imposes tax on digital profits. We do not yet know the impact this proposal, if implemented, would have on our financial results. A number of other jurisdictions ~~including the United Kingdom,~~ are considering enacting similar digital tax regimes. These efforts are alongside the OECD’s ongoing work, as part of its Base Erosion and Profit Shifting Action Plan, ~~to issue a final report in 2021~~ that, if implemented, provides a long-term, multilateral proposal on taxation of the digital economy. Any of the foregoing changes could have an adverse impact on our results of operations, cash flows, and financial condition.

~~Table of contents~~

Our results of operations may be harmed if we are required to collect sales and use, gross receipts, value-added, or similar taxes for our products in jurisdictions where we have not historically done so.

Sales and use, value-added, goods and services, and similar tax laws and rates vary greatly by jurisdiction. Our customers can be located in one jurisdiction, utilize our network and products through our network equipment in a different jurisdiction, and pay us from an account located in a third jurisdiction. This divergence, along with the jurisdiction-by-jurisdiction variance in tax laws, causes significant uncertainty in the tax treatment of our business. There is further uncertainty as to what constitutes sufficient physical presence or nexus for a national, state, or local jurisdiction to levy taxes, fees, and surcharges for sales made over the Internet, and there is also uncertainty as to whether our characterization of our network and products as not taxable in certain jurisdictions will be accepted by national, state, and local taxing authorities. In determining our tax filing obligations, management has made judgments regarding whether our activities in a jurisdiction rise to the level of taxability. These judgments may prove inaccurate, and one or more states or countries may seek to impose additional sales, use, or other tax collection obligations on us, including for past sales by us. It is possible that we could face sales tax audits and that our liability for these taxes could exceed our estimates as state and other tax authorities could still assert that we are obligated to collect additional amounts as taxes from our customers and remit those taxes to those authorities. Furthermore, the U.S. Supreme Court’s ruling in South Dakota v. Wayfair may permit wider enforcement of sales tax collection requirements. A successful assertion by a state, country, or other jurisdiction that we should have been or should be collecting additional sales, use, or other taxes on our network and products could, among other things, result in substantial tax liabilities for past sales, create significant administrative burdens for us, discourage customers from purchasing our network and products, or otherwise harm our business, results of operations, and financial condition.

Our international operations require us to exercise judgment in determining the applicability of tax laws, which may subject us to potentially adverse tax consequences.

We are subject to income taxes as well as non-income-based taxes, such as payroll, sales, use, value-added, property, and goods and services taxes, in both the United States and various foreign jurisdictions. Our domestic and international tax liabilities are subject to various jurisdictional rules regarding the timing and allocation of revenue and expenses. Additionally, the amount of income taxes paid is subject to our interpretation of applicable tax laws in the jurisdictions in which we file and to changes in tax laws. Significant judgment is required in determining our worldwide provision for income taxes and other tax liabilities. From time to time, we may be subject to income and non-income tax audits. While we believe we have complied with all applicable tax laws, there can be no assurance that a governing tax authority will not have a different interpretation of the law and assess us with additional taxes, including with respect to intercompany transfer pricing and the collection of sales and use tax, value-added tax, and goods and services tax. Should we be assessed with additional taxes, there could be a material adverse effect on our business, results of operations, and financial condition.

Our future effective tax rate may be affected by such factors as changes in tax laws, regulations, or rates, changing interpretation of existing laws or regulations, the impact of accounting for stock-based compensation, the impact of accounting for business combinations, changes in our international organization, and changes in our overall levels of income before tax. In addition, in the ordinary course of our global business, there are many intercompany transactions and calculations where the ultimate tax determination is uncertain. Although we believe that our tax estimates are reasonable, we cannot ensure that the final determination of tax audits or tax disputes will not be different from what is reflected in our historical income tax provisions and accruals. There can be no assurance that the outcomes from these continuous examinations will not have an adverse effect on our results of operations.

Table of contents

Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.

As of December 31, 2020, we had net operating loss carryforwards for U.S. federal income tax purposes of $448.7 million, net of uncertain tax positions, available to offset future U.S. federal taxable income that will begin to expire in 2029 for tax years beginning before December 31, 2017. Also as of December 31, 2020, we had net operating loss carryforwards for state income tax purposes of $215.8 million, net of uncertain tax positions, available to offset future state taxable income that will begin to expire in 2026. As of December 31, 2020, we had foreign tax credit carryforwards for federal income tax purposes of $1.8 million that will begin to expire, if not utilized, in 2025. Also as of December 31, 2020, we had federal research and development tax credit carryforwards of $8.2 million, net of uncertain tax positions, that will begin to expire in 2029 and state research and development tax credit carryforwards of $6.0 million, net of uncertain tax positions, that can be carried forward indefinitely.

~~Table of contents~~

Utilization of our net operating loss carryforwards and other tax attributes, such as research and development tax credits, may be subject to annual limitations, or could be subject to other limitations on utilization or benefit due to the ownership change limitations provided by Sections 382 and 383 of the Internal Revenue Code of 1986, as amended (the Code), and other similar provisions. Under Sections 382 and 383 of the Code, if a corporation undergoes an “ownership change,” the corporation’s ability to use its pre-change net operating loss carryforwards and other pre-change attributes, such as research tax credits, to offset its post-change income may be limited. In general, an “ownership change” will occur if there is a cumulative change in our ownership by “5-percent shareholders” that exceeds 50 percentage points over a rolling three-year period. Similar rules may apply under state tax laws. We may have experienced various ownership changes, as defined by the Code, as a result of past financing transactions (or other activities), and we may experience ownership changes in the future as a result of subsequent changes in our stock ownership, some of which may be outside our control.

Further, the Tax Act imposed limitations on the use of certain net operating losses; however, the Coronavirus Aid, Relief, and Economic Security Act (the CARES Act), which was enacted in March 2020 in response to the COVID-19 pandemic, temporarily removes such limitations for years 2018 through 2020. The CARES Act contains numerous income tax provisions, such as relaxing limitations on the deductibility of interest and the use of net operating losses arising in taxable years beginning after December 31, 2017. Future regulatory guidance under the CARES Act (as well as under the Tax Act) remains forthcoming, and such guidance could ultimately increase or lessen their impact on our business and financial condition. Our net operating loss carryforwards may also be subject to limitations in other jurisdictions. For example, California recently enacted legislation suspending the use of net operating losses for taxable years 2020, 2021, and 2022 for many taxpayers. Net operating loss carryforwards and other tax assets could expire before utilization and could be subject to limitations, which could harm our business, revenue, and financial results. It is also possible that Congress will enact additional legislation in connection with the COVID-19 pandemic, some of which may adversely impact our business.

Risks Related to International Operations

Our international operations expose us to significant risks, and failure to manage those risks could materially and adversely impact our business and results of operations.

Historically, we have derived a significant portion of our revenue from outside the United States. We derived ~~48%~~47% and ~~51%~~48% of our revenue from our international customers for the three months ended ~~June~~September 30, 2021 and 2020, respectively, and 48% and ~~51%~~50% for the ~~six~~nine months ended ~~June~~September 30, 2021 and 2020, respectively. We are continuing to adapt to and develop strategies to address international markets and our growth strategy includes expansion into geographies around the world, but there is no guarantee that such efforts will be successful. In addition, our global network includes co-location facilities located in more than ~~200~~250 cities and over 100 countries worldwide as of ~~June~~September 30, 2021. We expect that our international sales and network activities will continue to grow in the future, as we continue to pursue opportunities in international markets and further grow our network around the world. These international operations will require significant management attention and financial resources and are subject to substantial risks, including:

•political, economic, and social uncertainty, including the potential nationalization of key peering partners by foreign governments or political unrest that affects our ability to continue to work with particular peering partners, potential terrorist activities, and the unknown impact of regional or global health crises, or epidemic or pandemic diseases, such as the ongoing COVID-19 pandemic;

Table of contents

•changes in a specific country’s or region’s political or economic conditions, including in the United Kingdom as a result of its withdrawal from the EU, which is often referred to as "Brexit";

•unexpected costs for the localization of our products, including translation into foreign languages and adaptation for local practices and regulatory requirements;

•greater difficulty in enforcing contracts and accounts receivable collection, and longer collection periods;

•reduced or uncertain protection for intellectual property rights in some countries;

•requirements to open local offices or otherwise maintain a local presence in some countries, including Russia;

•greater risk of unexpected changes in regulatory practices, tariffs, and tax laws and treaties, including with respect to our business in China;

~~Table of contents~~

•greater risk of a failure of foreign employees and channel partners to comply with both U.S. and foreign laws, including antitrust regulations, anti-bribery laws, export and import control laws, and any applicable trade regulations ensuring fair trade practices;

•heightened security risks associated with our co-location facilities in high-risk countries and the software code and systems access shared with our service providers located in such countries; including in the Hong Kong region as a result of the National Security Law passed in June 2020;

•greater risks associated with third-party contractors that we use to install and maintain our hardware in co-location facilities in foreign countries and the limited background checks and screening that we can perform on such service providers;

•regulations related to privacy, data protection, security requirements, data localization, or content restriction that could pose risks to our intellectual property, increase the cost of doing business in a country, subject us to greater risks of claims and enforcement actions by regulators or others, subject us and our current and potential customers to burdensome requirements, increase the chance that current and potential customers may be unable to use our products or may be required to lessen or alter how they use our products, or create other disadvantages to our business or negative impacts on our results of operations;

•changes in laws, regulations, and costs affecting our U.K. operations and local employees due to Brexit;

•increased expenses incurred in establishing and maintaining office space and equipment for our international operations;

•greater difficulty in identifying, attracting, and retaining local qualified personnel and the costs and expenses associated with such activities;

•differing employment practices and labor relations issues, which may make expansion or contraction of our workforce, or changes in the terms of employment, in such countries more costly and time-consuming and subject us to a greater risk of disputes or litigation;

•increased regulatory requirements and litigation risk related to the presence of our physical infrastructure in countries around the world;

•difficulties in managing and staffing international offices and increased travel, infrastructure, and legal compliance costs associated with operating multiple international locations; and

•fluctuations in exchange rates between the U.S. dollar and foreign currencies in markets where we do business, particularly the United Kingdom and Singapore where we have large offices and pay employees in local currency.

The expansion of our existing international operations and entry into additional international markets will require significant management attention and financial resources. Our failure to successfully manage our international operations and the associated risks could limit the future growth of our business. In particular, we are exposed to risks in China, which amounts to a significant part of both our short-term and long-term revenue growth plans. Our Chinese operations are substantially dependent on our relationships with JD Cloud & AI and, in the short term, Baidu, and due to economic and political challenges in servicing the Chinese market, the loss of this arrangement could have a significant adverse effect on our business and results of operations.

Geo-political events such as Brexit may increase the likelihood of certain of these risks materializing or heighten their impact on us in affected regions. In particular, it is possible that the level of economic activity in the United

Table of contents

Kingdom and the rest of Europe will be adversely impacted and that we will face increased regulatory and legal complexities, including those related to tax, trade, data privacy, data protection, security, and employee relations, as a result of Brexit. Given the significance of our presence in the United Kingdom, such changes could be particularly costly and disruptive to our operations and business relationships. In addition, heightened use of trade restrictions such as tariffs or prohibitions on technology transfers to achieve diplomatic ends, including with respect to the current environment of economic trade negotiations and tensions between the Chinese and U.S. governments, could impact our ability to conduct our business as planned.

As discussed in greater detail above in our risk factors, in July 2020, the CJEU invalidated the U.S.-EU Privacy Shield, and this decision may result in European data protection regulators applying differing standards for, and requiring ad hoc verification of, transfers of personal data from the European Union to the United States. As a result of this uncertainty, our current and potential customers in the European Union may be concerned about whether they are able to transfer personal data to the United States in connection with the usage of our global network and

~~Table of contents~~

products. If these concerns result in our current and potential customers in Europe reducing their usage of our products, then our results of operations could be adversely impacted. Further, we anticipate needing to identify different transfer mechanisms and/or change our use of certain standard contractual clauses in order to lawfully transfer certain personal data from the European Union to the United States. This could result in substantial costs, require changes to our business practices, limit our ability to provide certain products in certain jurisdictions, or materially adversely affect our business and operating results.

Our business could be adversely impacted by the decision of foreign governments, Internet service providers, or others, to block transmission from Cloudflare IP addresses in order to enforce certain Internet content blocking efforts.

Some of our security products involve making origin IP addresses and other operational assets of our customers more difficult for cyber attackers to target. The evolving design of our network and products may create challenges for various organizations, including governments, that seek to block certain content based on IP address “black lists” or other mechanisms. This problem is exacerbated by the fact that a single Cloudflare IP address may be used for a number of Internet properties, and the Cloudflare IP used for any one Internet property may change over time. This means that efforts by ISPs to block a single domain name may end up blocking a number of other domains that share that Cloudflare IP address or domains that use that same Cloudflare IP address previously or subsequently. If these challenges become too difficult for those organizations to overcome, they could make the decision to block content in an overbroad manner or block completely websites and other Internet properties that are using our network and/or transmitted using known Cloudflare IP addresses. Some of these blocking efforts would be out of our control once they have been put in place and may limit our ability to provide our products on a fully global basis, which could reduce demand for our products among current or potential customers that are focused on the impacted regions or could otherwise adversely impact our business, results of operations, and financial condition.

Our network presence within China is dependent upon our commercial relationships with JD Cloud & AI, and, in the short term, Baidu, and any detrimental changes in, or the termination of, those relationships could jeopardize our ability to offer an integrated global network that includes China.

We believe our offering of an integrated global network that includes facilities in China is important to our existing and potential future customers. Our ability to continue to offer an integrated network presence that includes China currently is dependent on our commercial relationship with JD Cloud & AI and the continuation through December 31, 2021 of our historical commercial relationship with Baidu. Regulation of Internet infrastructure and traffic by the Chinese government creates challenges to the peering of Chinese and non-Chinese networks. We have strategic agreements with JD Cloud & AI and Baidu to provide solutions that accommodate the requirements imposed by Chinese regulations through JD Cloud & AI's and Baidu’s development and operation of facilities in China that are included as part of our network. Our agreement with JD Cloud & AI was announced in 2020 and the term of the agreement expires on April 1, 2023. There can be no assurance that we will be able to extend our agreement with JD Cloud & AI in the future or if any such extension would be available on comparable terms. Our existing agreement with Baidu expires on December 31, 2021 with respect to the inclusion of Baidu’s facilities in China as part of our network, and we do not expect that any further extension of the Baidu agreement will occur. Each of these agreements is subject to earlier termination by either party under certain circumstances such as the other party’s material breach. In addition, each of these agreements can be terminated by JD Cloud & AI or Baidu, as applicable, under certain circumstances if necessary Chinese governmental approvals are revoked or become limited or impaired or if public law or regulatory action by the Chinese or U.S. government expressly prohibits or materially restricts the collaboration contemplated by the agreement. The risk of such an early termination event

Table of contents

may have increased during the current environment of economic trade negotiations and tensions between the Chinese and U.S. governments.

Our customers that use our network presence in China through our JD Cloud & AI and Baidu commercial relationships are subject to Chinese laws and regulations of Internet infrastructure, traffic, and content. Under our agreements with JD Cloud & AI and Baidu, in some circumstances, these customers’ use of our Chinese network presence can be terminated if they violate these laws and regulations. The removal of our customers from our Chinese network presence could result in these customers deciding to terminate their overall relationship with us. In addition, any adverse publicity associated with the removal of some or all of our customers from our Chinese network presence as a result of the application of Chinese laws and regulations could cause us to experience adverse reputational and business consequences.

In addition, we currently are in the process of building out our new China network with JD Cloud & AI. If this build-up is interrupted or is not sufficiently completed prior to the termination of our access to the Baidu facilities, then our

~~Table of contents~~

ability to provide China network services to our customers could become impaired and the resulting loss of utility to many of our customers could materially harm our business.

If our commercial relationship with JD Cloud & AI is terminated, identifying an alternative solution in China could be difficult, time-consuming, and expensive. Even if an alternative solution is identified, we cannot be certain that the economic terms or performance of any such alternative arrangement will be comparable to our existing relationship with JD Cloud & AI, which could materially negatively impact our financial results and customer satisfaction with such alternative arrangement. A lack of network presence in China would represent a significant loss of utility to many of our customers and could materially harm our business.

We are subject to governmental trade sanctions laws, and export and import controls, that could impair our ability to compete in international markets and subject us to liability if we are not in full compliance with applicable laws.

Our business activities are subject to various economic and trade sanctions regulations administered by the U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC) and U.S. export control and similar foreign laws and regulations, including the U.S. Department of Commerce’s Export Administration Regulations (EAR). We incorporate encryption technology into certain of our products, and the encryption products and the underlying technology may be exported outside the United States only with the required export authorizations, including by license, a license exception, or other appropriate government authorizations, including the filing of classification requests or self-classification reports. Further, the U.S. economic sanctions laws and export control laws include restrictions or prohibitions on the sale or supply of most products and services to U.S. embargoed or sanctioned countries, governments, persons, and entities. Even though we take precautions and have implemented policies and practices to assist in compliance, there is a risk that we may not be in full compliance with these laws.

In 2019, we learned that we may have failed to comply with certain U.S. export-related filing and reporting requirements and may have submitted incorrect information to the U.S. government in connection with certain hardware exports. Upon learning of these potential violations and associated export control requirements, we promptly initiated a voluntary internal review and are taking remedial measures to prevent similar export control anomalies from occurring in the future. In May 2019, we submitted an initial voluntary self-disclosure to the Bureau of Industry and Security regarding potential violations of EAR and a voluntary self-disclosure to the Census Bureau regarding potential violations of the Foreign Trade Regulations. In July 2019, we filed the full and complete voluntary self-disclosures. The voluntary self-disclosure to the Census Bureau was completed with no penalties in November 2019. The voluntary self-disclosure to the Bureau of Industry and Security was completed with no penalties in June 2020.

In May 2019, we submitted an initial voluntary self-disclosure to OFAC related to our non-compliance with certain economic and trade sanctions programs, and we filed the full and complete voluntary self-disclosure to OFAC in July 2019. Specifically, we identified that our products were used by, or for the benefit of, certain individuals and entities included in OFAC’s Specially Designated Nationals and Blocked Persons List, including entities identified in OFAC’s counter-terrorism and counter-narcotics trafficking sanctions programs and individuals or entities affiliated with governments currently subject to comprehensive U.S. sanctions or located in regions subject to comprehensive sanctions. A small number of these parties made payments to us in connection with their use of our products. In January, July, September, and December 2020, as well as March, June, and ~~June~~September 2021, we responded to

Table of contents

additional questions from OFAC. The voluntary self-disclosure, which we may supplement as appropriate, remains under review by OFAC.

Although we have implemented, and are working to implement additional controls and screening tools designed to prevent similar activity from occurring in the future, there is no guarantee that we will not inadvertently provide our products to additional individuals, entities, or governments prohibited by U.S. sanctions in the future.

Additionally, we currently provide products to certain OFAC-sanctioned regions based upon general licenses issued by OFAC to engage in such activity. We continue to review the OFAC sanctions and our practices to verify compliance.

These efforts related to export controls and OFAC sanctions could result in negative consequences for us, including costs related to government investigations, financial penalties and harm to our reputation. The impact on us related to these matters could be substantial.

~~Table of contents~~

In addition, various countries regulate the import of certain technologies and have enacted or could enact laws that could limit our ability to provide our products and operate our network or could limit our customers’ ability to access or use our network and products in those countries.

If we are found to have violated the U.S. or foreign laws and regulations, we and certain of our employees could be subject to civil or criminal penalties, including the possible loss of export privileges and fines. We may be materially and adversely affected through penalties, reputational harm, loss of access to certain markets, loss of customers, or otherwise. Obtaining the necessary authorizations, including any required license, for a particular transaction may be time-consuming, is not guaranteed, and may result in the delay or loss of sales opportunities. In addition, changes in our network, products, or screening process, or changes in export, sanctions, and import laws, could delay the introduction and sale of subscriptions to our products in international markets, prevent customers in certain countries from accessing our network and products or, in some cases, prevent the provision of our network and products to certain countries, governments, persons, or entities altogether. Any decrease in our ability to sell our products could materially and adversely affect our business, results of operations, and financial condition.

We are exposed to fluctuations in currency exchange rates, which could negatively affect our results of operations.

Substantially all of our sales contracts are denominated in U.S. dollars and, therefore, substantially all of our revenue is not subject to foreign currency risk. However, a strengthening of the U.S. dollar could increase the real cost of our products to our customers outside of the United States, which could reduce demand for our products and adversely affect our financial condition and results of operations.

As our international operations expand, an increasing portion of our revenue and operating expenses is incurred outside the United States and is denominated in foreign currencies, such as the British Pound and Singapore Dollar. Accordingly, our revenue and operating expenses are increasingly subject to fluctuations due to changes in foreign currency exchange rates. As we continue to expand our international operations, we may become more exposed to foreign currency risk or remeasurement risk. If we become more exposed to currency fluctuations and are not able to successfully hedge against the risks associated with currency fluctuations, our results of operations could be materially and adversely affected.

Risks Related to Intellectual Property

We are currently, and may be in the future, party to intellectual property rights claims and other litigation matters that, if resolved adversely, could have a material impact on our business, results of operations, or financial condition.

We own a large number of patents, copyrights, trademarks, domain names, and trade secrets and, from time to time, are subject to litigation based on allegations of infringement, misappropriation, or other violations of intellectual property or other rights. As we face increasing competition and gain an increasingly high profile, the possibility of intellectual property rights claims, commercial claims, and other assertions against us grows. In addition, a number of companies in our industry hold a large number of patents and also protect their copyright, trade secret, and other intellectual property rights, and companies in the networking and security industry frequently enter into litigation based on allegations of patent infringement or other violations of intellectual property rights. We have in the past

Table of contents

been, are currently, and may from time to time in the future become, a party to litigation and disputes related to intellectual property, our business practices, and our products. For example, we are a defendant in lawsuits, both in the United States and abroad, seeking injunctive relief and/or damages against us based on alleged patent infringement and content that is made available through our customers’ websites, and these lawsuits include copyright infringement claims. We may also be subject to governmental and other regulatory investigations from time to time. The costs of supporting litigation and dispute resolution proceedings are considerable, and there can be no assurances that a favorable outcome will be obtained. Disputes, whether or not favorably resolved, may generate negative publicity and damage our reputation. We may need to settle litigation and disputes on terms that are unfavorable to us, or we may be subject to an unfavorable judgment that may not be reversible upon appeal. The terms of any settlement or judgment may require us to cease some or all of our operations or pay substantial amounts to the other party. With respect to any intellectual property rights claim, we may have to seek a license to continue practices found to be in violation of third-party rights, which may not be available on reasonable terms and may significantly increase our operating expenses. A license to continue such practices may not be available to us at all, and we may be required to develop alternative non-infringing technology or practices or discontinue the practices. The development of alternative, ~~non-~~

~~Table of contents~~

~~infringing~~non-infringing technology or practices could require significant effort and expense. Our business, results of operations, and financial condition could be materially and adversely affected as a result.

Indemnity provisions in various agreements potentially expose us to substantial liability for intellectual property infringement and other losses.

Our agreements with certain of our customers or other third parties may include indemnification or other provisions under which we agree to indemnify or otherwise be liable to them for losses suffered or incurred as a result of claims of intellectual property infringement, damages caused by us to property or persons, or other liabilities relating to or arising from the use of our network and products or other acts or omissions. The term of these contractual provisions often survives termination or expiration of the applicable agreement. We have in the past been sued on the basis of alleged violation of intellectual property rights in the form of patents and trade secrets. Although we were successful in defending the claims to date, as we continue to grow, the possibility of these and other intellectual property rights claims against us may increase. For any intellectual property rights indemnification claim against us or our customers, we may incur significant legal expenses and have to pay damages, pay license fees and/or stop using technology found to be in violation of the third party’s rights. Large indemnity payments could harm our business, results of operations, and financial condition. We may also have to seek a license for the disputed technology. Such license may not be available on reasonable terms, if at all, and may significantly increase our operating expenses or may require us to restrict our business activities and limit our ability to deliver certain products. As a result, we may also be required to develop alternative non-infringing technology, which could require significant effort and expense and/or cause us to alter our network or products, which could negatively affect our business.

From time to time, customers require us to indemnify or otherwise be liable to them for breach of confidentiality, violation of applicable law, or failure to implement adequate security measures with respect to their data stored, transmitted, or accessed using our network and products. Our standard Enterprise plan agreements provide limited indemnification to our customers based on third-party claims related to our violation of intellectual property rights, and some of our Enterprise plan agreements offer indemnification for claims beyond that scope. The existence of such a dispute may have adverse effects on our customer relationship and reputation and we may still incur substantial liability related to them.

Any assertions by a third party, whether or not successful, with respect to such indemnification obligations could subject us to costly and time-consuming litigation, expensive remediation and licenses, divert management attention and financial resources, harm our relationship with that customer and other current and prospective customers, reduce demand for our products, and harm our brand, business, results of operations, and financial condition.

Our failure to protect our intellectual property rights and proprietary information could diminish our brand and other intangible assets.

We rely and expect to continue to rely on a combination of patent, patent licenses, trade secret, domain name protection, trademarks, copyrights, and confidentiality and license agreements with our employees, consultants, and third parties in order to protect our intellectual property and proprietary rights. As of ~~June~~September 30, 2021, we had ~~more than 165~~170 issued patents and over 7075 pending patent applications in the United States and abroad. However, third parties may knowingly or unknowingly infringe our proprietary rights. Third parties may challenge our proprietary rights,

Table of contents

pending and future patent, trademark, and copyright applications may not be approved, and we may not be able to prevent infringement without incurring substantial expense. We have also devoted substantial resources to the development of our proprietary technologies and related processes, and we provide access to these technologies and processes to certain of our vendors and partners, including Baidu and JD Cloud & AI with respect to the facilities included within our network in China. We must protect this proprietary information in order to realize commercial benefit from our investment.

In order to protect our proprietary technologies and processes, we rely in part on trade secret laws and confidentiality agreements with our employees, consultants, and third parties. These agreements may not effectively prevent disclosure of confidential information and may not provide an adequate remedy in the event of unauthorized disclosure of confidential information. In addition, others may independently discover our trade secrets or develop similar technologies and processes, in which case we would not be able to assert trade secret rights against them. Laws in certain jurisdictions may afford little or no trade secret protection, and any changes in, or unexpected interpretations of, the intellectual property laws in any country in which we operate may compromise our ability to enforce our intellectual property rights. We may not be effective in policing unauthorized use of our intellectual

~~Table of contents~~

property rights, and even if we do detect violations, costly and time-consuming litigation could be necessary to enforce and determine the scope of our proprietary rights, and any such litigation could be unsuccessful, lead to the invalidation of our proprietary rights, or lead to counterclaims by other parties against us. If the protection of our proprietary rights is inadequate to prevent use or appropriation by third parties, the value of our network and products, brand, and other intangible assets may be diminished and competitors may be able to more effectively replicate our network and products and their features. Any of these events could materially and adversely affect our business, results of operations, and financial condition.

We depend and rely upon software and technologies licensed from third parties to operate our business, and interruptions or the unavailability of these technologies may adversely affect our products, network, business, and results of operations.

We rely on software, services, and other technology from third parties that we incorporate into, or integrate with, our network and products. We also rely on software, services, and other technology from third parties in order to operate critical functions of our business, including enterprise resource planning and customer relationship management services. If the software, services, or other technology we rely on become unavailable due to extended outages, the third-party provider disabling our access, expiration or termination of licenses, or because they are otherwise no longer available on commercially reasonable terms, our expenses could increase, and our ability to operate our network, provide our products, and our results of operations could be impaired until equivalent software, technology, or services are obtained or replacements are developed, all of which could adversely affect our business.

If we are unable to license necessary technology from third parties now or in the future, we may be forced to acquire or develop alternative technology, which we may be unable to do in a commercially feasible manner or at all, and we may be required to use alternative technology of lower quality or performance. This could limit and delay our ability to offer new or competitive products and increase our costs of production. As a result, our business and results of operations could be significantly harmed.

We cannot be certain that those from whom we license software and other technology are not infringing the intellectual property rights of third parties or have sufficient rights to the licensed intellectual property in all jurisdictions in which we may sell our products. Accordingly, our use of this intellectual property may expose us to third-party claims of infringement. In addition, many licenses are non-exclusive and may not prevent our competitors from licensing the same technology on equivalent or more favorable terms.

Some of our technology incorporates “open source” software, we license some of our software through open source projects and we voluntarily make available some of our software on an open source basis, which could negatively affect our ability to sell our products, subject us to possible litigation, and be used by other companies to compete against us.

Our network and products incorporate software licensed under open source licenses, including open source software included in software we receive from third-party commercial software vendors. Use of open source software may entail greater risks than use of third-party commercial software, as open source licensors generally do not provide support, updates, or warranties, or other contractual protections regarding infringement claims or the quality of the software. In addition, the wide availability of source code incorporated in our products could allow

Table of contents

hostile parties to more easily identify security vulnerabilities in our network and products. The terms of some open source licenses may provide that under certain conditions we could be required to release the source code of our proprietary software, and to make our proprietary software available under open source licenses, including authorizing further modification and redistribution. In the event that certain portions of our proprietary software are determined to be subject to such requirements by an open source license, we could be required to publicly release the affected portions of our source code, re-engineer all or a portion of our network or applicable products, or otherwise be limited in the licensing of our products, each of which provide an advantage to our competitors or other entrants to the market, create security vulnerabilities in our products, and could reduce or eliminate the value of our products. Because the terms of open source licenses are novel and have not been widely interpreted by courts, we could be subject to lawsuits by parties claiming ownership of what we believe to be open source software or by third parties seeking to enforce the terms of open source licenses against us in a manner we do not anticipate. In addition, we voluntarily make available certain portions of our software on an open source basis to the public and such software could then be used by other companies to compete against us.

~~Table of contents~~

Any unanticipated disclosure of, or litigation regarding, our source code and any open source software incorporated into our source code could result in adverse judgments and liabilities, require us to reengineer all or a portion of our network and products, limit the marketing of our products, provide an advantage to our competitors or other entrants to the market, create new security vulnerabilities or highlight existing security vulnerabilities in our network and products, and reduce or eliminate the value of our network and products. We cannot assure you that our processes for controlling our use of open source software in our network and products will be effective.

Risks Related to Ownership of Our Class A Common Stock

The trading price of our Class A common stock may be volatile, and you could lose all or part of your investment.

Prior to our initial public offering (IPO), there was no public market for shares of our Class A common stock. The trading price of our Class A common stock is likely to be volatile and could be subject to fluctuations in response to various factors, some of which are beyond our control. These fluctuations could cause you to lose all or part of your investment in our Class A common stock. Factors that could cause fluctuations in the trading price of our Class A common stock include:

•price and volume fluctuations in the overall stock market from time to time;

•volatility in the trading prices and trading volumes of technology stocks;

•changes in operating performance and stock market valuations of other technology companies generally, or those in our industry in particular;

•sales of shares of our Class A common stock and Class B common stock by us or our stockholders;

•issuance of shares of our Class A common stock, whether in connection with an acquisition or upon conversion of some or all of our outstanding Notes);

•failure of securities analysts to maintain coverage of us, changes in financial estimates by securities analysts who follow our company, or our failure to meet these estimates or the expectations of investors;

•the financial projections we may provide to the public, any changes in those projections, or our failure to meet those projections;

•announcements by us or our competitors of new products, features, or services;

•the public’s reaction to our press releases, other public announcements, and filings with the SEC;

•rumors and market speculation involving us or other companies in our industry;

•actual or anticipated changes in our results of operations or fluctuations in our results of operations;

•actual or anticipated developments in our business, our competitors’ businesses or the competitive landscape generally;

•investments we may make in equity that is, or may become, publicly held, and volatility we may experience due to changes in the market prices of such equity investments;

Table of contents

•litigation involving us, our industry, or both, or investigations by regulators into our operations or those of our competitors;

•developments or disputes concerning our intellectual property or other proprietary rights;

•actual or perceived data security breaches or other data security incidents;

•announced or completed acquisitions of businesses, products, services, or technologies by us or our competitors;

•new laws or regulations or new interpretations of existing laws or regulations applicable to our business;

•changes in accounting standards, policies, guidelines, interpretations, or principles;

•any significant change in our management; and

•general economic conditions and slow or negative growth of our markets, including due to the impact of the ongoing COVID-19 pandemic.

~~Table of contents~~

In addition, in the past, following periods of volatility in the overall market and the market price of a particular company’s securities, securities class action litigation has often been instituted against these companies. This litigation, if instituted against us, could result in substantial costs and a diversion of our management’s attention and resources.

The dual class structure of our common stock has the effect of concentrating voting control with those stockholders who held our capital stock prior to the completion of our initial public offering, and it may depress the trading price of our Class A common stock.

Our Class B common stock has 10 votes per share and our Class A common stock has one vote per share. As of ~~June~~September 30, 2021, our directors, executive officers, and holders of more than 5% of our common stock, and their respective affiliates, held in the aggregate ~~79.3%~~78.1% of the voting power of our capital stock, with our co-founders together holding approximately ~~57.7%~~56.8%. Because of the ten-to-one voting ratio between our Class B and Class A common stock, the holders of our Class B common stock collectively continue to control a majority of the combined voting power of our common stock and therefore are able to control all matters submitted to our stockholders for approval. This concentrated control will limit or preclude the ability of holders of Class A common stock to influence corporate matters for the foreseeable future, including the election of directors, amendments of our organizational documents, and any merger, consolidation, sale of all or substantially all of our assets, or other major corporate transaction requiring stockholder approval. In addition, this may prevent or discourage unsolicited acquisition proposals or offers for our capital stock that you may feel are in your best interest as one of our stockholders.

Future transfers by holders of shares of Class B common stock and the cessation of employment by holders of our Class B common stock generally result in those shares converting to Class A common stock, subject to limited exceptions, such as certain transfers effected for estate planning purposes and transfers between related entities. The conversion of Class B common stock to Class A common stock will have the effect, over time, of increasing the relative voting power of those individual holders of Class B common stock who retain their shares in the long-term.

In July 2017, FTSE Russell and Standard & Poor’s announced that they would cease to include most newly public companies utilizing dual or multi-class capital structures in their indices. Affected indices include the Russell 1000, Russell 2000, and Russell 3000 and the S&P 500, S&P MidCap 400, and S&P SmallCap 600, which S&P indices together make up the S&P Composite 1500. Under the announced policies, our multi-class capital structure in some cases may make us ineligible for inclusion in some or all of these indices, and as a result, mutual funds, exchange-traded funds, and other investment vehicles that attempt to passively track these indices may not invest in our stock if we are not included. It is unclear what effect, if any, these policies have on the valuations of publicly traded companies excluded from the indices, but it is possible that they may depress these valuations compared to those of other similar companies that are included.

Substantial future sales could depress the market price of our Class A common stock.

The market price of our Class A common stock could decline as a result of sales of a large number of shares of such stock, and the perception that these sales could occur may also depress the market price of our Class A common stock.

Table of contents

Under our investors’ rights agreement, certain stockholders can require us to register shares owned by them for public sale in the United States. In addition, we file registration statements to register shares reserved for future issuance under our equity compensation plans. As a result, subject to the satisfaction of applicable exercise periods, the shares issued upon exercise of outstanding stock options or upon settlement of outstanding RSU awards are available for immediate resale in the United States in the open market.

Sales of our shares may make it more difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate. These sales also could cause the trading price of our Class A common stock to fall and make it more difficult for you to sell shares of our Class A common stock.

We have broad discretion over the use of the net proceeds from our financing activities, and we may not use them effectively.

We cannot specify with any certainty the particular uses of the net proceeds that we received from our financing activities, including from our IPO and the ~~issuance~~issuances of the Notes, and our management has broad discretion in the

~~Table of contents~~

application of the net proceeds. The failure by our management to apply these proceeds effectively could adversely affect our business, results of operations, and financial condition. Pending their use, we may invest our proceeds in a manner that does not produce income or that loses value. Our investments may not yield a favorable return to our investors and may negatively impact the price of our Class A common stock.

Delaware law and provisions in our amended and restated certificate of incorporation and amended and restated bylaws could make a merger, tender offer, or proxy contest difficult, thereby depressing the market price of our Class A common stock.

Our status as a Delaware corporation and the anti-takeover provisions of the Delaware General Corporation Law may discourage, delay, or prevent a change in control by prohibiting us from engaging in a business combination with an interested stockholder for a period of three years after the person becomes an interested stockholder, even if a change of control would be beneficial to our existing stockholders. In addition, our amended and restated certificate of incorporation and amended and restated bylaws contain provisions that may make the acquisition of our company more difficult, including the following:

•our dual-class common stock structure, which provides Mr. Prince and Ms. Zatlyn with the ability to significantly influence the outcome of matters requiring stockholder approval, even if they own significantly less than a majority of the shares of our outstanding Class A common stock and Class B common stock;

•our Board of Directors is classified into three classes of directors with staggered three-year terms and directors are only able to be removed from office for cause;

•vacancies on our Board of Directors will be able to be filled only by our Board of Directors and not by stockholders;

•only the Chair of our Board of Directors, our Chief Executive Officer, or a majority of our entire Board of Directors are authorized to call a special meeting of stockholders;

•certain litigation against us can only be brought in Delaware;

•our amended and restated certificate of incorporation authorizes undesignated preferred stock, the terms of which may be established and shares of which may be issued, without the approval of the holders of Class A common stock;

•advance notice procedures apply for stockholders to nominate candidates for election as directors or to bring matters before an annual meeting of stockholders;

•our stockholders will only be able to take action at a meeting of stockholders and not by written consent; and

•any amendment of the above anti-takeover provisions in our amended and restated certificate of incorporation or amended and restated bylaws will require the approval of two-thirds of the combined vote of our then-outstanding shares of Class A common stock and Class B common stock.

These anti-takeover defenses could discourage, delay, or prevent a transaction involving a change in control of our company. These provisions could also discourage proxy contests and make it more difficult for stockholders to elect directors of their choosing and to cause us to take other corporate actions they desire, any of which, under certain

Table of contents

circumstances, could limit the opportunity for our stockholders to receive a premium for their shares of our capital stock, and could also affect the price that some investors are willing to pay for our Class A common stock.

Our amended and restated bylaws provide that the Court of Chancery of the State of Delaware and the federal district courts of the United States will be the exclusive forums for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to choose the judicial forum for disputes with us or our directors, officers or employees.

Our amended and restated bylaws provide that the Court of Chancery of the State of Delaware is the exclusive forum for the following types of actions or proceedings under Delaware statutory or common law: (i) any derivative action or proceeding brought on our behalf; (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers, or other employees to us or our stockholders; (iii) any action arising pursuant to any provision of the Delaware General Corporation Law, our amended and restated certificate of incorporation or our amended and restated bylaws; or (iv) any other action asserting a claim that is governed by the internal affairs doctrine shall be the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have

~~Table of contents~~

jurisdiction, the federal district court for the District of Delaware), in all cases subject to the court having jurisdiction over indispensable parties named as defendants. Our amended and restated bylaws further provide that the U.S. federal district courts will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act.

Any person or entity purchasing or otherwise acquiring any interest in any of our securities shall be deemed to have notice of and consented to this provision. These exclusive-forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum of its choosing for disputes with us or our directors, officers, or other employees, which may discourage lawsuits against us and our directors, officers, and other employees. If a court were to find the exclusive-forum provision in our amended and restated bylaws to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving the dispute in other jurisdictions, which could harm our results of operations.

Our Class A common stock market price and trading volume could decline if equity or industry analysts do not publish research or publish inaccurate or unfavorable research about our business.

The trading market for our Class A common stock depends in part on the research and reports that equity or industry analysts publish about us or our business. The analysts’ estimates are based upon their own opinions and are often different from our estimates or expectations. If one or more of the analysts who cover us downgrade our Class A common stock or publish inaccurate or unfavorable research about our business, the price of our securities would likely decline. If few securities analysts commence coverage of us, or if one or more of these analysts cease coverage of us or fail to publish reports on us regularly, demand for our securities could decrease, which might cause the price and trading volume of our Class A common stock to decline.

An active trading market for our Class A common stock may not be sustained.

Our Class A common stock is listed on the NYSE under the symbol “NET.” However, we cannot assure you of the likelihood that an active trading market for our Class A common stock will be maintained, the liquidity of any trading market, your ability to sell your shares of our Class A common stock when desired, or the prices that you may obtain for your shares.

We do not intend to pay dividends for the foreseeable future.

We have never declared nor paid cash dividends on our capital stock. We currently intend to retain any future earnings to finance the operation and expansion of our business, and we do not expect to declare or pay any dividends in the foreseeable future. As a result, stockholders must rely on sales of their Class A common stock after price appreciation as the only way to realize any future gains on their investment.

Risks Related to our Outstanding Convertible Senior Notes

Servicing our future debt, including the Notes, may require a significant amount of cash, and we may not have sufficient cash flow from our business to pay our indebtedness.

Table of contents

In May 2020, we issued $575.0 million in aggregate principal amount of the ~~Notes. The~~2025 Notes ~~are senior unsecured obligations~~and in August 2021, we issued $1,293.8 million in aggregate principal amount of the Company and will mature on May 15, 2025, unless earlier redeemed, repurchased, or converted, and are governed by the terms of the Indenture dated May 15, 2020 (the Indenture). The interest rate is fixed at 0.75% per annum and is payable semi-annually in arrears on May 15 and November 15 of each year, beginning on November 15, 2020.2026 Notes. Our ability to make scheduled payments of the principal of, to pay interest on or to refinance our indebtedness, including the Notes, depends on our future performance, which is subject to economic, financial, competitive, and other factors beyond our control. Our business may not generate cash flow from operations in the future sufficient to service our debt and make necessary capital expenditures. If we are unable to generate such cash flow, we may be required to adopt one or more alternatives, such as selling assets, restructuring debt, or obtaining additional debt financing or equity capital on terms that may be onerous or highly dilutive. Our ability to refinance any future indebtedness will depend on the capital markets and our financial condition at such time. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt obligations. In addition, any of our future debt agreements may contain restrictive covenants that may prohibit us from adopting any of these alternatives. Our failure to comply with these covenants could result in an event of default which, if not cured or waived, could result in the acceleration of our debt.

~~Table of contents~~

In addition, our indebtedness, combined with our other financial obligations and contractual commitments, could have other important consequences. For example, it could:

•make us more vulnerable to adverse changes in general U.S. and worldwide economic, industry, and competitive conditions and adverse changes in government regulation;

•limit our flexibility in planning for, or reacting to, changes in our business and our industry;

•place us at a disadvantage compared to our competitors who have less debt;

•limit our ability to borrow additional amounts to fund acquisitions, for working capital, and for other general corporate purposes; and

•make an acquisition of our company less attractive or more difficult.

Any of these factors could harm our business, results of operations, and financial condition. In addition, if we incur additional indebtedness, the risks related to our business and our ability to service or repay our indebtedness would increase.

We may not have the ability to raise the funds necessary for cash settlement upon conversion of the Notes or to repurchase the Notes for cash upon a fundamental change, and our future debt may contain limitations on our ability to pay cash upon conversion of the Notes or to repurchase the Notes.

Holders of the Notes have the right to require us to repurchase their Notes of the applicable series upon the occurrence of ~~a fundamental change at~~ a fundamental change (which is defined in the ~~Indenture for the Notes to include events such as~~applicable Indenture) at a ~~change of control)~~ repurchase price equal to 100% of the principal amount of ~~the~~such Notes to be repurchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change repurchase ~~date.~~datefor such series of Notes. In addition, upon conversion of the Notes, unless we elect to deliver solely shares of our Class A common stock to settle such conversion (other than paying cash in lieu of delivering any fractional share), we will be required to make cash payments in respect of the Notes being converted. However, we may not have enough available cash or be able to obtain financing at the time we are required to make repurchases of Notes surrendered therefore or Notes being converted. In addition, our ability to repurchase the Notes or to pay cash upon conversions of the Notes may be limited by law, by regulatory authority or by agreements governing our future indebtedness. Our failure to repurchase the Notes of a series at a time when the repurchase is required by the applicable Indenture ~~governing the Notes~~ or to pay any cash payable on future conversions of the Notes of such series as required by such Indenture would constitute a default under ~~the~~such Indenture. A default under ~~the~~either Indenture or the occurrence of a fundamental change ~~itself~~under either series of Notes could also lead to a default under agreements governing our future indebtedness. If the repayment of the related indebtedness were to be accelerated after any applicable notice or grace periods, we may not have sufficient funds to repay the indebtedness and repurchase the Notes or make cash payments upon conversions ~~thereof.~~thereofin accordance with the terms of the applicable Indenture. Any failure by us to repay the indebtedness and repurchase the Notes or make cash payments upon conversions thereof, in each case, when required to do so pursuant to the terms of the applicable Indenture could harm our business, results of operations, and financial condition.

The conditional conversion feature of the Notes, when triggered, may adversely affect our financial condition and operating results.

If the conditional conversion feature of ~~the~~either series of Notes is triggered, holders of the ~~Notes~~applicable series are entitled to convert ~~the~~their Notes at any time during specified periods at their option. The 2025 Notes are currently

100

Table of contents

convertible at the option of the holder until ~~September 30,~~December 31, 2021. If one or more holders elect to convert their Notes, unless we elect to satisfy our conversion obligation by delivering solely shares of our Class A common stock (other than paying cash in lieu of delivering any fractional share), we would be required to settle a portion or all of our conversion obligation through the payment of cash, which could adversely affect our liquidity. In addition, even if holders do not elect to convert their Notes, we could be required under applicable accounting rules to reclassify all or a portion of the outstanding principal of the Notes as a current rather than long-term liability, which would result in a material reduction of our net working capital.

Transactions relating to the Notes may affect the value of our Class A common stock.

The conversion of some or all of the Notes would dilute the ownership interests of our existing stockholders to the extent we satisfy our conversion obligation by delivering shares of our Class A common stock upon any conversion of such Notes. For example, in August 2021, we entered into privately-negotiated exchange agreements with certain holders of the 2025 Notes for the exchange of approximately $400.7 million in cash and approximately 7.6 million shares of our Class A Common Stock for $400.0 million in aggregate principal amount of the 2025 Notes. The Notes may become convertible at the option of their holders under certain ~~circumstances.~~ circumstances set forth in the applicable Indenture. For

~~Table of contents~~

instance, the 2025 Notes are currently convertible at the option of the holder until ~~September 30,~~December 31, 2021. If holders of the Notes elect to convert their Notes, we may settle our conversion obligation by delivering to them a significant number of shares of our Class A common stock, which would cause dilution to our existing stockholders.

In connection with the pricing of ~~the~~each series of Notes, we entered into privately negotiated capped call transactions with the applicable option counterparties. The capped call transactions are expected generally to reduce the potential dilution upon conversion of the applicable series of Notes and/or offset any cash payments we are required to make in excess of the principal amount of such converted Notes, as the case may be, with such reduction and/or offset subject to a cap.

In connection with establishing their initial hedges of the capped call transactions, the applicable option counterparties or their respective affiliates entered into various derivative transactions with respect to our Class A common stock and/or purchased shares of our Class A common stock concurrently with or shortly after the pricing of the applicable series of Notes. From time to time, the option counterparties or their respective affiliates may modify their hedge positions by entering into or unwinding various derivatives with respect to our Class A common stock and/or purchasing or selling our Class A common stock or other securities of ours in secondary market transactions prior to the maturity of the applicable series of Notes (and are likely to do so following any conversion, repurchase, or redemption of ~~the~~such Notes, to the extent we exercise the relevant election under the applicable capped call transactions). This activity could also cause a decrease and/or increased volatility in the market price of our Class A common stock.

We are subject to counterparty risk with respect to the capped call transactions.

The option counterparties are financial institutions, and we will be subject to the risk that any or all of them might default under the capped call transactions. Our exposure to the credit risk of the option counterparties will not be secured by any collateral. Past global economic conditions have resulted in the actual or perceived failure or financial difficulties of many financial institutions. If an option counterparty becomes subject to insolvency proceedings, we will become an unsecured creditor in those proceedings with a claim equal to our exposure at that time under the capped call transactions with such option counterparty. Our exposure will depend on many factors but, generally, an increase in our exposure will be correlated to an increase in the market price and in the volatility of our Class A common stock. In addition, upon a default by an option counterparty, we may suffer adverse tax consequences and more dilution than we currently anticipate with respect to our Class A common stock. We can provide no assurance as to the financial stability or viability of the option counterparties.

The accounting method for convertible debt securities that may be settled in cash, such as the Notes, could have a material effect on our reported financial results.

Under current accounting principles, the initial liability carrying amount of the Notes is the fair value of a similar debt instrument that does not have a conversion feature, valued using our cost of capital for straight, unconvertible debt. We reflect the difference between the net proceeds from the offering of the applicable series of Notes and the initial carrying amount for such series as a debt discount for accounting purposes, which is amortized into interest expense over the term of the applicable series of Notes. As a result of this amortization, we expect to recognize more interest expense for the Notes for accounting purposes, which will result in lower reported income or higher

101

Table of contents

reported losses. The lower reported income or higher reported losses resulting from this accounting treatment could depress the trading price of our Class A common stock.

In August 2020, the Financial Accounting Standards Board published an Accounting Standards Update, or ASU 2020-06, eliminating the separate accounting for the debt and equity components as described above. ASU 2020-06 will be effective for the Company for the fiscal year, including interim periods within, beginning January 1, 2022.

When we adopt ASU 2020-06, we expect the elimination of the separate accounting described above to reduce the interest expense that we expect to recognize for the Notes for accounting purposes. In addition, ASU 2020-06 eliminates the possible use of the treasury stock method for convertible instruments that can be settled in whole or in part with equity, and instead requires application of the “if-converted” method. Under that method, diluted earnings per share would generally be calculated assuming that all the Notes were converted solely into shares of common stock at the beginning of the reporting period, unless the result would be antidilutive. The application of the if-converted method may reduce our reported diluted earnings per share.

General Risk Factors

If we fail to maintain an effective system of disclosure controls and internal control over financial reporting, our ability to produce timely and accurate financial statements or comply with applicable regulations could be impaired.

We are subject to the reporting requirements of the Securities Exchange Act of 1934, as amended (the Exchange Act), the Sarbanes-Oxley Act of 2002 (the Sarbanes-Oxley Act), and the rules and regulations of the applicable listing standards of the New York Stock Exchange (the NYSE). We expect that the requirements of these rules and regulations will continue to increase our legal, accounting, and financial compliance costs, make some activities more difficult, time-consuming, and costly, and place significant strain on our personnel, systems, and resources.

The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. We are continuing to develop and refine our disclosure controls and other procedures that are designed to ensure that information required to be disclosed by us in the reports that we file with the SEC is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms and that information required to be disclosed in reports under the Exchange Act is accumulated and communicated to our principal executive and financial officers. We are also continuing to improve our internal control over financial reporting. In order to maintain and improve the effectiveness of our disclosure controls and procedures and internal control over financial reporting, we have expended, and anticipate that we will continue to expend, significant resources, including accounting-related costs, and significant management oversight. In addition, our independent registered public accounting firm is required to audit the effectiveness of our internal control over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act annually. Testing, or the subsequent testing by our independent registered public accounting firm, may reveal material weaknesses or significant deficiencies. If material weaknesses are identified or we are not able to comply with the requirements of Section 404 in a timely manner, our reported financial results could be materially misstated, we could receive an adverse opinion regarding our internal control over financial reporting from our independent registered public

~~Table of contents~~

accounting firm, we could be subject to investigations or sanctions by regulatory authorities, and we could incur substantial expenses.

Our current controls and any new controls that we develop may become inadequate because of changes in conditions in our business. Further, weaknesses in our disclosure controls and internal control over financial reporting may be discovered in the future. Any failure to develop or maintain effective controls or any difficulties encountered in their implementation or improvement could harm our results of operations or cause us to fail to meet our reporting obligations and may result in a restatement of our financial statements for prior periods. Any failure to implement and maintain effective internal control over financial reporting also could adversely affect the results of periodic management evaluations and annual independent registered public accounting firm attestation reports regarding the effectiveness of our internal control over financial reporting that we will eventually be required to include in our periodic reports that will be filed with the SEC. Ineffective disclosure controls and procedures and internal control over financial reporting could also cause investors to lose confidence in our reported financial and other information, which would likely have a negative effect on the trading price of our Class A common stock. In addition, if we are unable to continue to meet these requirements, we may not be able to remain listed on the NYSE.

102

Table of contents

Our business is subject to the risks of catastrophic events.

The occurrence of any catastrophic event, including an earthquake, fire, flood, tsunami, or other weather event, power loss, telecommunications failure, software or hardware malfunctions, epidemic or pandemic diseases (such as the ongoing COVID-19 pandemic), cyber-attack, war, or terrorist attack, could result in lengthy interruptions in our service. Our corporate headquarters is located in the San Francisco Bay Area and one of our core co-location facilities is located in the U.S. Pacific Northwest, both regions known for seismic activity, and we also have a second core co-location facility in Luxembourg. Our insurance coverage may not compensate us for losses that may occur in the event of an earthquake or other significant natural disaster. In addition, acts of terrorism could cause disruptions to the Internet or the economy as a whole. Even with our disaster recovery arrangements, our service could be interrupted. If our systems were to fail or be negatively impacted as a result of a natural disaster or other event, our ability to deliver products to our customers would be impaired or we could lose critical data.

Our partners, suppliers, and customers are also subject to the risk of catastrophic events. In those events, our ability to deliver our products in a timely manner, as well as the demand for our products, may be divided on account of factors outside our control.

The requirements of being a public company may strain our resources, divert management’s attention, and affect our ability to attract and retain executive management and qualified board members.

We are subject to the reporting requirements of the Exchange Act, the Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, the listing requirements of the NYSE, and other applicable securities rules and regulations. Compliance with these rules and regulations increases our legal and financial compliance costs, makes some activities more difficult, time-consuming, or costly, and increases demand on our systems and resources. The Exchange Act requires, among other things, that we file annual, quarterly, and current reports with respect to our business and results of operations. The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. In order to maintain and, if required, improve our disclosure controls and procedures and internal control over financial reporting to meet this standard, significant resources and management oversight is required. We are required to disclose changes made in our internal control and procedures on a quarterly basis and we will be required to furnish a report by management on, among other things, the effectiveness of our internal control over financial reporting. As a result of the complexity involved in complying with the rules and regulations applicable to public companies, our management’s attention may be diverted from other business concerns, which could adversely affect our business and results of operations. Although we have already hired additional employees and have engaged outside consultants to assist us in complying with these requirements, we may need to hire more employees in the future or engage additional outside consultants, which will increase our operating expenses.

In addition, changing laws, regulations, and standards relating to corporate governance and public disclosure are creating uncertainty for public companies, increasing legal and financial compliance costs, and making some activities more time consuming. These laws, regulations, and standards are subject to varying interpretations, in many cases due to their lack of specificity, and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices. We

~~Table of contents~~

intend to invest substantial resources to comply with evolving laws, regulations, and standards, and this investment may result in increased general and administrative expenses and a diversion of management’s time and attention from revenue-generating activities to compliance activities. If our efforts to comply with new laws, regulations, and standards differ from the activities intended by regulatory or governing bodies due to ambiguities related to their application and practice, regulatory authorities may initiate legal proceedings against us and our business may be adversely affected.

Failure to comply with the aforementioned rules and regulations may make it more expensive for us to maintain director and officer liability insurance, and in the future we may be required to accept reduced coverage or incur substantially higher costs to obtain coverage. These factors could also make it more difficult for us to attract and retain qualified members of our Board of Directors, particularly to serve on our audit committee and compensation committee, and qualified executive officers.

As a result of disclosure of information in our filings with the SEC, our business and financial condition are visible, which we believe may result in threatened or actual litigation, including by competitors and other third parties. If such claims are successful, our business and results of operations could be adversely affected, and even if the claims do not result in litigation or are resolved in our favor, these claims, and the time and resources necessary to

103

Table of contents

resolve them, could divert the resources of our management and adversely affect our business and results of operations.
