Unless the context otherwise requires, we use the terms “Etsy,” the “Company,” “we,” “us,” and “our” in this Quarterly Report on Form 10-Q (“Quarterly Report”) to refer to Etsy, Inc. and, where appropriate, our consolidated subsidiaries.

See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Key Operating and Financial Metrics” for the definitions of the following terms used in this Quarterly Report: “active buyer,” “active seller,” “Adjusted EBITDA,” “GMS,” “non-U.S. GMS,” “mobile GMS,” and “currency-neutral GMS growth.”

Etsy has used, and intends to continue using, its investor relations website and the Etsy News Blog (blog.etsy.com/news) to disclose material non-public information and to comply with its disclosure obligations under Regulation FD.

Note Regarding Forward-Looking Statements

This Quarterly Report contains forward-looking statements within the meaning of the federal securities laws. Forward-looking statements include information relating to our opportunity; the impact of our “Right to Win” strategy and levers for growth, marketing, and product initiatives and investments on our business and operating results, including future gross merchandise sales (“GMS”) and revenue growth; the impact of our Offsite Ads offering on our future financial performance; our plans for acquisitions and strategic investments, our “House of Brands” strategy, including integration of our recent acquisitions of Depop and Elo7, and their potential impact on our growth and results of operations; our intended economic, social and ecological impacts; and the uncertain impacts that the COVID-19 pandemic or its eventual abatement may have on our business, strategy, operating results, key metrics, financial condition, profitability, and cash flows, on changes in overall levels of consumer spending, on e-commerce generally, and on volatility in the global economy. Forward-looking statements include all statements that are not historical facts. In some cases, forward-looking statements can be identified by terms such as “aim,” “anticipate,” “believe,” “could,” “enable,” “estimate,” “expect,” “goal,” “intend,” “may,” “plan,” “potential,” “project,” “seek,” “should,” “target,” “will,” “would” or similar expressions and derivative forms and/or negatives of those terms.

Forward-looking statements are not guarantees of performance and involve known and unknown risks, uncertainties, and other factors that may cause our actual results, performance, or achievements to be materially different from any future results, performance, or achievements expressed or implied by the forward-looking statements. Those risks include those described in Part II, Item 1A, “Risk Factors” and elsewhere in this Quarterly Report. Given these uncertainties, you should read this Quarterly Report in its entirety and not place undue reliance on any forward-looking statements in this Quarterly Report.

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 and, although 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.

Moreover, we operate in a 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 made in this Quarterly Report. In light of these risks, uncertainties, and assumptions, the future events and trends discussed in this Quarterly Report may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements. In addition, the global economic climate and additional or unforeseen effects from the ongoing COVID-19 pandemic may amplify many of these risks.

Forward-looking statements represent our beliefs and assumptions only as of the date of this Quarterly Report. We disclaim any obligation to update forward-looking statements.

Summary Risk Factors

Our business is subject to numerous risks. The following summary highlights some of the risks we are exposed to in the normal course of our business activities. This summary is not complete and the risks summarized below are not the only risks we face. You should review and consider carefully the risks and uncertainties described in more detail in the “Risk Factors” section of this Quarterly Report which includes a more complete discussion of the risks summarized below as well as a discussion of other risks related to our business and an investment in our common stock.

Financial Performance and Operational Risks Related to Our Business

•We have experienced rapid growth, and we may not have the infrastructure, human resources, or operational resources to sustain continued growth at our recent pace.

•The ongoing COVID-19 pandemic is unprecedented and has impacted, and the pandemic and its eventual abatement may continue to impact, our GMS, and could impact our results of operations in numerous ways that remain volatile and unpredictable.

•Our quarterly operating results may fluctuate, which could cause our stock price to decline. The price of our common stock has been and will likely continue to be volatile and declines in the price of our common stock could subject us to litigation.

•We may fail to meet our publicly announced guidance or other expectations about our business and future operating results, which could cause our stock price to decline.

3

•Our business could suffer if we experience a technology disruption that results in a loss of information, if personal data or sensitive information about users or employees is misused or disclosed, or if we or our third-party providers are unable to protect against technology vulnerabilities, service interruptions, security breaches, or other cyber incidents.

•The trustworthiness of our marketplaces and the connections within our communities are important to our success. Our business, financial performance, and growth depend on our ability to attract and retain active and engaged communities of buyers and sellers. If we are unable to retain our existing buyers and sellers and activate new ones, our financial performance could decline.

•Our business depends on continued and unimpeded access to third party services, platforms, and infrastructure that we rely upon to maintain and scale our platforms.

•We have experienced rapid domestic and global growth, and we may be subject to expanded and potentially uninsured risk, making it more difficult for us to maintain profitability in the future.

•Our business could be adversely affected by economic downturns, natural disasters, political crises, geopolitical changes or other macroeconomic conditions which have in the past and may in the future negatively impact our business and financial performance.

•Our ability to attract and hire a diverse pipeline of talent and retain key employees is important to our success. If we experience significant attrition or turnover it could impact our ability to grow our business.

Strategic Risks Related to Our Business and Industry

•We face intense competition and may not be able to compete effectively.

•If we are not able to keep pace with technological changes, and enhance current and develop new offerings to respond to the changing needs of sellers and buyers, our business may be harmed.

•If the widely adopted mobile, social, search and advertising solutions that we, our sellers and our buyers rely on as part of our key offering are no longer available or effective, or if access to these major platforms is limited, the use of our marketplaces could decline.

•If we do not demonstrate progress against our Impact strategy or if our Impact strategy is not perceived to be adequate, our reputation could be harmed. We could also damage our reputation and the value of our brands if we fail to demonstrate that our commitment to our Impact strategy enhances our overall financial performance.

•Expanding our operations outside of the United States is part of our strategy, and the growth of our business could be harmed if our international expansion efforts do not succeed.

•Our recent acquisitions of Depop Limited (“Depop”) and Elo7 Serviços de Informática S.A. (“Elo7”) may create strains on our management, technology and operational resources and may prove to be costlier and take longer to integrate than we anticipate.

•We may expand our business through additional acquisitions of other businesses or assets or strategic partnerships and investments, which may divert management’s attention and/or prove to be unsuccessful.

•We have a significant amount of convertible debt that may be settled in cash and may incur additional debt in the future.

Regulatory, Compliance, and Legal Risks

•Compliance and protection under evolving global legal and regulatory requirements including privacy and data protection laws, tax laws, product liability laws, antitrust laws, intellectual property and counterfeiting regulations, may materially impact our time, resources, and ability to grow our business.

•Expanding our operations in Latin America and India may expose us to additional risks.

•We have been involved in, and in the future may be involved in, litigation and regulatory matters that are expensive and time consuming and that may require changes to our strategy, the features of our platforms and how our business operates.

•We may be subject to intellectual property or other claims, which, even if untrue, could damage our brands, require us to pay significant damages, and could limit our ability to use certain technologies or business strategies in the future.

4

Other Risks

•Future sales and issuances of our common stock, or rights to purchase common stock, including upon conversion of our convertible notes, could result in additional dilution to our stockholders and could cause the price of our common stock to decline.

Note 1—Basis of Presentation and Summary of Significant Accounting Policies

Description of Business

Etsy, Inc. (the “Company” or “Etsy”) operates a “House of Brands,” two-sided online marketplaces that connect millions of passionate and creative buyers and sellers. The Company’s primary marketplace, Etsy.com, is the global marketplace for unique and creative goods. The Company generates revenue primarily from transaction, listing, and payments processing fees, and on-site advertising and shipping label services.

Basis of Consolidation

The consolidated financial statements include the accounts of Etsy and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. On July 2, 2021, Etsy acquired all the outstanding shares of Elo7 Serviços de Informática S.A. (“Elo7”) by means of a merger, and on July 12, 2021 Etsy acquired all of the issued share capital of Depop Limited (“Depop”) pursuant to a share purchase. The financial results of Elo7 and Depop have been included in Etsy’s Consolidated Financial Statements from the respective dates of acquisition. See “Note 5—Business Combinations.”

Basis of Presentation

The accompanying unaudited interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and pursuant to the applicable rules and regulations of the Securities and Exchange Commission (“SEC”). The Company has condensed or omitted certain information and notes normally included in complete annual financial statements prepared in accordance with GAAP. These unaudited interim consolidated financial statements should therefore be read in conjunction with the audited consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K filed with the SEC on February 26, 2021 (the “Annual Report”). In the opinion of management, all material adjustments, which are of a normal and recurring nature, necessary for a fair presentation of the results for the periods presented have been reflected in the consolidated financial statements. The results of operations of any interim period are not necessarily indicative of the results of operations for the full annual period or any future period due to seasonal and other factors.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires the Company to make estimates and judgments that affect the amounts reported and disclosed in the consolidated financial statements and accompanying notes. Actual results could differ from these estimates and judgments. The accounting estimates that require management’s most subjective judgments include: stock-based compensation; income taxes, including the estimate of the annual effective tax rate at interim periods and evaluation of uncertain tax positions; purchase price allocations for business combinations and valuation of acquired intangible assets, developed technology, and goodwill. As of September 30, 2021, the effects of the ongoing COVID-19 pandemic and progress towards its abatement on the Company’s business, results of operations, and financial condition continue to evolve. As a result, many of the Company’s estimates and judgments required increased judgment and carry a higher degree of variability and volatility. As additional information becomes available, the Company’s estimates may change materially in future periods.

Stock-Based Compensation

Service based stock options, service based restricted stock units (“RSUs”), and performance based restricted stock units (“PBRSUs”) are awarded to employees, officers, and members of the Company’s Board of Directors. The PBRSUs include financial performance based restricted stock units (“Financial PBRSUs”) and total shareholder return performance based restricted stock units (“TSR PBRSUs”), both of which have performance and service vesting requirements. The Company recognizes forfeitures as they occur.

The Company calculates the fair value of stock options on the date of grant using the Black-Scholes option-pricing model. The fair value of RSUs is measured using the closing price of the Company’s common stock on Nasdaq on the grant date. Additionally, the fair value of the Financial PBRSUs is determined using a probability assessment and the fair value of the TSR PBRSUs with market conditions are determined using a Monte-Carlo simulation model.

13

Etsy, Inc.

Notes to Consolidated Financial Statements

For PBRSUs, the Company recognizes stock-based compensation expenses on a straight-line basis over the longer of the derived, explicit, or implicit service period. As of interim and annual reporting periods, the Financial PBRSUs stock-based compensation expense is adjusted based on expected achievement of performance targets, while TSR PBRSUs stock-based compensation expense is not adjusted.

Recently Issued Accounting Pronouncements

In October 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2021-08—Business Combinations (Topic 805)—Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires contract assets and contract liabilities acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with Accounting Standards Codification Topic 606—Revenue from Contracts with Customers (“ASC 606”). Under current GAAP, an acquirer generally recognizes assets acquired and liabilities assumed in a business combination, including contract assets and contract liabilities arising from revenue contracts with customers, at fair value on the acquisition date. This ASU will result in the acquirer recording acquired contract assets and liabilities on the same basis that would have been recorded by the acquiree before the acquisition under ASC 606. The amendments in this ASU do not affect the accounting for other assets or liabilities that may arise from revenue contracts with customers in accordance with ASC 606, such as refund liabilities, or in a business combination, such as customer-related intangible assets and contract-based intangible assets. The new guidance is effective for annual and interim periods beginning after December 15, 2022. Early adoption is permitted, including in interim periods, for any financial statements that have not yet been issued. This update should be applied prospectively to business combinations occurring on or after the effective date of the amendments. The Company is currently evaluating the impact that this new guidance may have on its consolidated financial statements.

Recently Adopted Accounting Pronouncements

In August 2020, the FASB issued ASU 2020-06—Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity's Own Equity (Subtopic 815-40)—Accounting For Convertible Instruments and Contracts in an Entity's Own Equity (“ASU 2020-06”). ASU 2020-06 simplifies accounting for convertible instruments by removing major separation models previously required under GAAP. Consequently, more convertible debt instruments will be reported as a single liability instrument with no separate accounting for embedded conversion features through equity. Without an initial allocation of proceeds to the conversion option, the debt will likely have a lower discount, thereby resulting in less non-cash interest expense through accretion. ASU 2020-06 removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception, which will permit more equity contracts to qualify for it. ASU 2020-06 also simplifies the diluted net income per share calculation in certain areas. The new guidance is effective for annual and interim periods beginning after December 15, 2021, and early adoption is permitted for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. This update permits the use of either the modified retrospective or fully retrospective method of transition.

The Company early adopted this standard, effective as of January 1, 2021, on a modified retrospective basis. The adoption of this standard had a material effect on the Company’s consolidated financial statements. The most significant effects related to the 0.125% Convertible Senior Notes due 2027 (the “2020 Notes”), 0.125% Convertible Senior Notes due 2026 (the “2019 Notes”), and 0% Convertible Senior Notes due 2023 (the “2018 Notes” and together with the 0.25% Convertible Senior Notes due 2028 (the “2021 Notes”), the 2020 Notes, and the 2019 Notes, the “Notes”), and included derecognition of the unamortized debt discount, which was recorded as a direct deduction from the Notes, resulting in an increase in long-term debt, net of approximately $264 million; derecognition of the equity component, which represents the value of the conversion option on the issuance date of the Notes outstanding, resulting in a reduction in additional paid-in capital of approximately $229 million, net of taxes; derecognition of deferred tax liabilities of approximately $63 million; and reversal of the cumulative debt discount recognized as interest expense in the Company’s Consolidated Statements of Operations since the date of issuance of each of the Notes to the period ending December 31, 2020, resulting in a decrease of accumulated deficit of approximately $28 million, net of taxes. The Company also had a reduction in interest expense due to the adoption of ASU 2020-06 as the debt discount has been derecognized and, effective January 1, 2021, there is no amortization of the debt discount. The Company did not incur any impact to liquidity or cash flows. When calculating net income per share of common stock attributable to common stockholders, the Company uses the if-converted method as required under ASU 2020-06 to determine the dilutive effect of the Notes.

Revenue	$	532,429	$	451,478	$	1,611,975	$	1,108,270

Etsy.com marketplace revenue is comprised of the fees a seller pays for marketplace activities. Marketplace activities include listing an item for sale, completing sales transactions, and using the Company’s payments platforms to process payments. Across the Company’s “House of Brands,” Reverb, Depop, and Elo7 marketplace revenue is comprised of seller transaction fees and payments fees, similar to Etsy.com, but these marketplaces do not charge a listing fee to their sellers.

Etsy.com services revenue is comprised of the fees a seller pays for the Company’s optional other services, which primarily include on-site advertising services and shipping labels. Similar services revenue is recognized across the Company’s “House of Brands,” including from Reverb’s Bump on-site advertising and Reverb, Depop, and Elo7’s shipping labels.

For more information on the Company’s critical accounting policies related to Etsy.com revenue recognition, see “Note 1—Basis of Presentation and Summary of Significant Accounting Policies” in the Notes to Consolidated Financial Statements of the Company’s Annual Report, which is incorporated herein by reference.

Note 3—Income Taxes

The Company’s provision or benefit from income taxes in interim periods is determined using an estimate of the annual effective tax rate, adjusted for discrete items, if any, that are taken into account in the relevant period. Each quarter the Company updates its estimate of the annual effective tax rate, and if its estimated tax rate changes, the Company makes a cumulative adjustment. The estimate of the annual effective income tax rate for the full year is applied to the respective interim period, taking into account year-to-date amounts and projected results for the full year.

The Company’s quarterly tax provision, and its quarterly estimate of the annual effective tax rate, is subject to significant variation due to several factors, including variability in accurately predicting its income or loss before tax and the mix of jurisdictions to which they relate, taxable income or loss in each jurisdiction, changes in its stock price, audit-related developments, acquisitions, changes in its deferred tax assets and liabilities and their valuation, foreign currency gains (losses), changes in statutes, regulations, case law, and administrative practices, principles, and interpretations related to tax, including changes to the global tax framework, competition, and other laws and accounting rules in various jurisdictions, and relative changes of expenses or losses for which tax benefits are not recognized. Additionally, the effective tax rate can be more or less volatile based on the amount of income or loss before tax. For example, the impact of discrete items and non-deductible expenses on the effective tax rate is greater when income before income taxes is lower.

For the nine months ended September 30, 2021, the Company’s effective income tax rate was (1.4)% representing an income tax benefit recorded on net income before tax. The effective tax rate for the nine months ended September 30, 2021 was lower than the U.S. statutory rate of 21% primarily due to excess tax benefits from employee stock-based compensation, the impact from foreign operations that are subject to lower tax rates, and a benefit related to a research and development tax credit, partially offset by state income taxes.

Although management believes its tax positions and related provisions reflected in the consolidated financial statements are fully supportable, it recognizes that these tax positions and related provisions may be challenged by various tax authorities. These tax positions and related provisions are reviewed on an ongoing basis and are adjusted as additional facts and information become available, including progress on tax audits, changes in interpretation of tax laws, developments in case law and closing of statute of limitations. To the extent that the ultimate results differ from the original or adjusted estimates of the Company, the effect will be recorded in the provision for income taxes.

The provision for income taxes involves a significant amount of management judgment regarding interpretation of relevant facts and laws in the jurisdictions in which the Company operates. Future changes in applicable laws, projected levels of taxable income and tax planning could change the effective tax rate and tax balances recorded by the Company. In addition, tax authorities periodically review income tax returns filed by the Company and can raise issues regarding its filing positions, timing and amount of income and deductions, and the allocation of income among the jurisdictions in which the Company operates. A significant period of time may elapse between the filing of an income tax return and the ultimate resolution of an issue raised by a revenue authority with respect to that return. Any adjustments as a result of any examination, may result in additional taxes or penalties against the Company. If the ultimate result of these audits differ from original or adjusted estimates, they could have a material impact on the Company’s tax provision.

The amount of unrecognized tax benefits included in the Consolidated Balance Sheets increased $2.9 million in the nine months ended September 30, 2021, from $23.7 million as of December 31, 2020 to $26.6 million as of September 30, 2021. The total amount of unrecognized tax benefits that, if recognized, would favorably affect the effective tax rate is $25.6 million as of September 30, 2021. Although the timing of the resolution and/or closure of audits is highly uncertain, it is reasonably possible that the balance of gross unrecognized tax benefits could significantly change in the next 12 months. Given the number of years remaining subject to examination and the number of matters being examined, at this time, the Company is unable to estimate the full range of possible adjustments to the balance of gross unrecognized tax benefits.

The Company recognizes interest and/or penalties related to uncertain tax positions in income tax expense.

Note 5—Business Combinations

Depop Acquisition

On July 12, 2021, the Company acquired all of the outstanding capital stock of Depop, an online global peer-to-peer fashion resale marketplace. The Company believes Depop extends its market opportunity in the high frequency apparel sector, specifically in the fast-growing resale space, and deepens the Company’s reach into the Gen Z consumer. The fair value of consideration transferred of $1.493 billion consisted of: (1) cash consideration paid of $1.479 billion, net of cash acquired, (2) non-cash consideration of $4.8 million representing the portion of the replacement equity awards issued in connection with the acquisition that was associated with services rendered through the date of the acquisition, and (3) $9.2 million holdback pending the finalization of certain purchase price items which were resolved and paid in the fourth quarter of 2021. The portion of the replacement equity awards associated with services rendered post-acquisition will be recorded as post-combination expense on a straight-line basis over the remaining vesting period of the awards. Additionally, deferred consideration awards will be issued to certain Depop executives, which will also be recorded as post-combination expense on a straight-line basis over the three-year mandatory service period associated with the deferred consideration. Neither of these awards was included in the fair value of the consideration transferred. For more information on these awards, see Note 11—Stock-Based Compensation.

The acquisition was accounted for under the acquisition method of accounting. Accordingly, the purchase price was allocated to the assets acquired and liabilities assumed based upon their estimated fair values as of the date of the acquisition. The excess of the purchase price over the estimated fair value of the net assets acquired was recorded as goodwill, which consists largely of assembled workforce, expanded market opportunities, and value creation across the Company’s businesses. The resulting goodwill is not expected to be deductible for tax purposes.

The allocation of the purchase price has been prepared on a preliminary basis and changes to the allocation to certain assets and liabilities, including tax estimates, may be revised as additional information becomes available. The Company will finalize the acquisition accounting within the required measurement period of one year.

Depop Purchase Price Allocation

The following table summarizes the allocation of the purchase price (at fair value) to the assets acquired and liabilities of Depop assumed as of July 12, 2021 (the date of acquisition) (in thousands, except years):

	Preliminary Purchase Price Allocation		Estimated Useful Life (in years)
Current assets	$	4,249
Property and equipment other	1,299		2-5
Developed technology	84,661		5
Trademark	245,657		20

Elo7 Acquisition

On July 2, 2021, the Company acquired all the outstanding shares of Elo7 (including Elo7, Ltd. and related subsidiaries entities), by means of a merger, an e-commerce marketplace in Brazil focused on unique, handmade items. The Company sees significant potential in Brazil's e-commerce sector, which is still in early stages of development and fueled by one of the largest economies in the world. The Company believes having a well known local brand will help Etsy, Inc. to better capitalize on this opportunity. The fair value of consideration transferred of $212.1 million consisted of: (1) cash consideration paid of $211.3 million, net of cash acquired, and (2) non-cash consideration of $0.8 million representing the portion of the replacement equity awards issued in connection with the acquisition that was associated with services rendered through the date of the acquisition. The portion of the replacement equity awards associated with services rendered post-acquisition will be recorded as post-combination expense on a straight-line basis over the remaining vesting period of the awards, and were therefore not included in the fair value of the consideration transferred. For more information on these awards, see Note 11—Stock-Based Compensation.

The acquisition was accounted for under the acquisition method of accounting. Accordingly, the purchase price was allocated to the assets acquired and liabilities assumed based upon their estimated fair values as of the date of the acquisition. The excess of the purchase price over the estimated fair value of the net assets acquired was recorded as goodwill, which consists largely of assembled workforce, expanded market opportunities, and value creation across the Company’s businesses. The resulting goodwill is not expected to be deductible for tax purposes.

The allocation of the purchase price has been prepared on a preliminary basis and changes to the allocation to certain assets and liabilities, including tax estimates, may be revised as additional information becomes available. The Company will finalize the acquisition accounting within the required measurement period of one year.

Elo7 Purchase Price Allocation

Revenue and Earnings

Revenue and net loss were $17.4 million and $26.8 million, respectively, for Depop and Elo7, in the aggregate, from their respective dates of acquisition through September 30, 2021. Acquisition-related expenses are expensed as incurred. They were recorded in general and administrative expenses and were $25.0 million and $35.0 million for the three and nine months ended September 30, 2021, respectively. They primarily related to advisory, legal, valuation, and other professional fees.

Unaudited Supplemental Pro Forma Information

The following unaudited pro forma summary presents consolidated information of the Company, including Depop and Elo7, as if the business combinations had occurred on January 1, 2020, the earliest period presented herein (in thousands):

	Three Months Ended   September 30,				Nine Months Ended   September 30,
	2021		2020		2021		2020
Revenue	$	534,395	$	474,910	$	1,656,452	$	1,162,420
Net income	108,781		89,040		332,246		184,423

The pro forma financial information includes adjustments that are directly attributable to the business combinations and are factually supportable. The pro forma adjustments include incremental amortization of intangible and developed technology assets, based on preliminary values of each asset, and remove non-recurring transaction costs directly associated with the acquisition, such as legal and other professional service fees, and the pro forma tax impact for such adjustments. Cost savings or operating synergies expected to result from the acquisition are not included in the pro forma results. For the three and nine months ended September 30, 2021, the pro forma financial information excludes $44.2 million and $58.4 million, respectively, of non-recurring acquisition-related expenses incurred prior to the effective dates of the business combinations. For the nine months ended September 30, 2020, the pro forma financial information includes $1.1 million of non-recurring acquisition-related expenses incurred post effective dates of the business combinations. These pro forma results are illustrative only and not indicative of the actual results of operations that would have been achieved nor are they indicative of future results of operations.

Goodwill

The change in the carrying amount of goodwill from December 31, 2020 to September 30, 2021 is as follows, with the addition primarily due to the acquisitions of Depop and Elo7 (in thousands):

	Net Book Value
Balance as of December 31, 2020	$	140,810
Business combinations	1,290,108
Foreign currency translation adjustments	(45,704)
Balance as of September 30, 2021	$	1,385,214

The Company has determined it has four operating segments, Etsy, Reverb, Depop, and Elo7, which qualify for aggregation as one reportable segment, for purposes of allocating resources and evaluating financial performance. The Company has determined it has four reporting units and will perform the annual goodwill impairment test for each reporting unit during the fourth quarter.

With respect to the goodwill generated as a result of the above purchase price allocations, the Company determined that the estimated fair value of the two newly acquired reporting units was not substantially in excess of its carrying value, due to the proximity of the acquisition dates.

Note 6—Fair Value Measurements

The Company has characterized its investments in marketable securities, based on the priority of the inputs used to value the investments, into a three-level fair value hierarchy. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1), and lowest priority to unobservable inputs (Level 3). If the inputs used to measure the investments fall within different levels of the hierarchy, the categorization is based on the lowest level input that is significant to the fair value measurement of the investment. Investments recorded in the accompanying Consolidated Balance Sheets are categorized based on the inputs to valuation techniques as follows:

Level 1—These are investments where values are based on unadjusted quoted prices for identical assets in an active market that the Company has the ability to access.

Level 2—These are investments where values are based on quoted market prices in markets that are not active or model derived valuations in which all significant inputs are observable in active markets.

Level 3—These are financial instruments where values are derived from techniques in which one or more significant inputs are unobservable. The Company did not have any Level 3 instruments as of September 30, 2021 and December 31, 2020.

Short- and long-term investments and certain cash equivalents consist of investments in debt securities that are available-for-sale. The following table sets forth the cost, gross unrealized losses, gross unrealized gains, and fair values of the Company’s investments as of the dates indicated (in thousands):

Notes to Consolidated Financial Statements

The Company evaluates fair value for each individual security in the investment portfolio. All investments in an unrealized loss position have been in an unrealized loss position for less than 12 months as of September 30, 2021.

The Company typically invests in short- and long-term instruments, including fixed-income funds and U.S. Government and agency securities aligned with the Company’s investment strategy. The maturities of the Company’s non-current marketable debt securities generally range from greater than 12 and up to 37 months.

Disclosure of Fair Values

The Company’s financial instruments that are not measured at fair value in the Consolidated Balance Sheets include the Notes, see “Note 8—Debt.” The Company estimates the fair value of the Notes through inputs that are observable in the market, classified as Level 2 as described above. The following table presents the carrying value and estimated fair value of the Notes as of the dates indicated (in thousands):

	As of September 30, 2021				As of December 31, 2020

(1)Upon adoption of ASU 2020-06 as of January 1, 2021, the carrying value of the Notes increased due to the derecognition of the unamortized debt discount, as described in “Note 1—Basis of Presentation and Summary of Significant Accounting Policies—Recently Adopted Accounting Pronouncements.” The increase in the carrying value of the 2018 Notes was offset by the conversion of $43.9 million of the 2018 Notes in the nine months ended September 30, 2021 (see “Note 8—Debt”).

The carrying value of other financial instruments, including cash, accounts receivable, accounts payable, funds receivable and seller accounts, and funds payable and amounts due to sellers approximate fair value due to the immediate or short-term maturity associated with these instruments.

Note 8—Debt

2021 Convertible Debt

In June 2021, the Company issued $1.0 billion aggregate principal amount of the 2021 Notes in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”). The net proceeds from the sale of the 2021 Notes were approximately $986.7 million after deducting the initial purchasers’ discount and offering expenses and before the 2021 Capped Call Transactions, as described below, and the repurchase of stock, as described in “Note 10—Stockholders’ Equity.”

The 2021 Notes are convertible into shares of the Company’s common stock based upon an initial conversion rate of 4.0518 shares of the Company’s common stock per $1,000 principal amount of 2021 Notes (equivalent to an initial conversion price of approximately $246.80 per share). The conversion rate will be subject to adjustment upon the occurrence of certain specified events, including certain distributions and dividends to all or substantially all of the holders of the Company’s common stock. Based on the terms of the 2021 Notes, when a conversion notice is received, the Company has the option to pay or deliver cash, shares of the Company’s common stock, or a combination thereof. Accordingly, the Company cannot be required to settle the 2021 Notes in cash and, therefore, the 2021 Notes are classified as long-term debt as of September 30, 2021.

The 2021 Notes will mature on June 15, 2028, unless earlier converted, redeemed, or repurchased. Prior to the close of business on the business day immediately preceding February 15, 2028, holders may convert all or a portion of their 2021 Notes only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on September 30, 2021 (and only during such calendar quarter), if the last reported sale price of the Company’s 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 10 consecutive trading day period (the “measurement period”) in which the trading price per $1,000 principal amount of 2021 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 common stock and the conversion rate on each such trading day; (3) if the Company calls the 2021 Notes for redemption at any time prior to the close of business on the second scheduled trading day immediately preceding the redemption date, but only with respect to the 2021 Notes called (or deemed called) for redemption; or (4) upon the occurrence of specified corporate events. On and after February 15, 2028 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their 2021 Notes at any time, regardless of the foregoing circumstances.

The Company may redeem all or any portion of the 2021 Notes, at the Company’s option, subject to partial redemption limitations, on or after June 20, 2025, if the last reported sale price of the Company’s common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive), including the trading day immediately preceding the date on which the Company provides notice of redemption, during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which the Company provides notice of redemption at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date.

If a fundamental change occurs prior to the maturity date, holders may require the Company to repurchase all or a portion of their 2021 Notes for cash at a price equal to 100% of the principal amount of the 2021 Notes to be repurchased. Holders of 2021 Notes who convert their 2021 Notes in connection with a notice of a redemption or a make-whole fundamental change may be entitled to a premium in the form of an increase in the conversion rate of the 2021 Notes. As of September 30, 2021, none of the conditions permitting the holders of the 2021 Notes to early convert have been met.

In accounting for the issuance of the 2021 Notes, the Company recorded the 2021 Notes as a liability at face value. Transaction costs attributable to the liability were recorded as a direct deduction from the related debt liability in the Consolidated Balance Sheet and are amortized to interest expense over the term of the 2021 Notes.

2021 Capped Call Transactions

The Company used $85.0 million of the net proceeds from the 2021 Notes to enter into privately negotiated capped call instruments (“2021 Capped Call Transactions”) with certain financial institutions. The 2021 Capped Call Transactions are expected generally to reduce the potential dilution and/or offset the cash payments the Company is required to make in excess of the principal amount of the 2021 Notes upon conversion of the 2021 Notes in the event that the market price per share of the Company’s common stock is greater than the strike price of the 2021 Capped Call Transactions with such reduction and/or offset subject to a cap. The 2021 Capped Call Transactions have an initial cap price of $340.42 per share of the Company’s common stock, which represents a premium of 100% over the last reported sale price of the Company’s common stock on June 8, 2021, and is subject to certain adjustments under the terms of the 2021 Capped Call Transactions. Collectively, the 2021 Capped Call Transactions cover, initially, the number of shares of the Company’s common stock underlying the 2021 Notes, subject to anti-dilution adjustments substantially similar to those applicable to the 2021 Notes.

The 2021 Capped Call Transactions do not meet the criteria for separate accounting as a derivative as they are indexed to the Company’s stock. The premiums paid for the 2021 Capped Call Transactions have been included as a net reduction to additional paid-in capital within stockholders’ equity.

2020 Convertible Debt

In August 2020, the Company issued $650.0 million aggregate principal amount of the 2020 Notes in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act. The net proceeds from the sale of the 2020 Notes were approximately $639.5 million after deducting the offering expenses. The 2020 Notes are convertible into shares of the Company’s common stock based upon an initial conversion rate of 5.0007 shares of the Company’s common stock per $1,000 principal amount of 2020 Notes (equivalent to an initial conversion price of approximately $199.97 per share). The Company used $74.7 million of the net proceeds from the 2020 Notes offering to enter into separate capped call instruments (“2020 Capped Call Transactions”) with the initial purchasers and/or their respective affiliates.

During any calendar quarter preceding May 1, 2027 in which the closing price of the Company’s common stock exceeds 130% of the applicable conversion price of the 2020 Notes on at least 20 of the last 30 consecutive trading days of the quarter, holders may, in the immediate quarter following, convert all or a portion of their 2020 Notes. Based on the daily closing prices of the Company’s stock during the quarter ended September 30, 2021, holders of the 2020 Notes are not eligible to convert their 2020 Notes during the fourth quarter of 2021. Based on the terms of the 2020 Notes, when a conversion notice is received, the Company has the option to pay or deliver cash, shares of the Company’s common stock, or a combination thereof. Accordingly, the Company cannot be required to settle the 2020 Notes in cash and, therefore, the 2020 Notes are classified as long-term debt as of September 30, 2021.

2019 Convertible Debt

In September 2019, the Company issued $650.0 million aggregate principal amount of the 2019 Notes in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act. The net proceeds from the sale of the 2019 Notes were $639.5 million after deducting the initial purchasers’ discount and offering expenses. The 2019 Notes are convertible based upon an initial conversion rate of 11.4040 shares of the Company’s common stock per $1,000 principal amount of 2019 Notes (equivalent to an initial conversion price of approximately $87.69 per share). The Company used $76.2 million of the net proceeds from the 2019 Notes offering to enter into separate capped call instruments (“2019 Capped Call Transactions”) with the initial purchasers and/or their respective affiliates.

During any calendar quarter preceding June 1, 2026 in which the closing price of the Company’s common stock exceeds 130% of the applicable conversion price of the 2019 Notes on at least 20 of the last 30 consecutive trading days of the quarter, holders may, in the immediate quarter following, convert all or a portion of their 2019 Notes. Based on the daily closing prices of the Company’s stock during the quarter ended September 30, 2021, holders of the 2019 Notes are eligible to convert their 2019 Notes during the fourth quarter of 2021. Based on the terms of the 2019 Notes, when a conversion notice is received, the Company has the option to pay or deliver cash, shares of the Company’s common stock, or a combination thereof. Accordingly, the Company cannot be required to settle the 2019 Notes in cash and, therefore, the 2019 Notes are classified as long-term debt as of September 30, 2021.

2018 Convertible Debt

In March 2018, the Company issued $345.0 million aggregate principal amount of the 2018 Notes in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act. The net proceeds from the sale of the 2018 Notes were $335.0 million after deducting the initial purchasers’ discount and offering expenses. The 2018 Notes are convertible based upon an initial conversion rate of 27.5691 shares of the Company’s common stock per $1,000 principal amount of 2018 Notes (equivalent to an initial conversion price of approximately $36.27 per share). The Company used $34.2 million of the net proceeds from the 2018 Notes offering to enter into separate capped call instruments (“2018 Capped Call Transactions”) with the initial purchasers and/or their respective affiliates.

During the third quarter of 2020, the Company paid $137.2 million in cash and issued approximately 7.3 million shares of Etsy’s common stock to repurchase $301.1 million aggregate principal amount of its outstanding 2018 Notes through privately negotiated transactions. Concurrently, the Company repurchased 1.3 million shares of Etsy’s common stock for $166.2 million, in order to effectively complete the partial repurchase of 2018 Notes principal value in cash, and the conversion premium in shares. The equity component impact associated with the conversion premium on the 2018 Notes was a net increase to additional paid-in capital of $143.2 million. This transaction was accounted for as an extinguishment of debt and recorded in accordance with the applicable accounting standard in the year ended December 31, 2020. The Company recognized a non-cash loss on extinguishment of $16.9 million. This loss was calculated by comparing the carrying value of the debt component with the fair value of a similar liability that does not have an associated convertible feature immediately prior to extinguishment as well as writing off any remaining unamortized deferred debt issuance costs at the time of extinguishment.

During the nine months ended September 30, 2021, the Company paid $43.9 million in cash and issued approximately 1.0 million shares of Etsy’s common stock to settle conversion notices of $43.8 million aggregate principal amount of the outstanding 2018 Notes. The debt conversion transactions were accounted for in accordance with ASU 2020-06, which was adopted in the first quarter of 2021. See “Note 1—Basis of Presentation and Summary of Significant Accounting Policies—Recently Adopted Accounting Pronouncements” for additional information.

During any calendar quarter preceding November 1, 2022 in which the closing price of the Company’s common stock exceeds 130% of the applicable conversion price of the 2018 Notes on at least 20 of the last 30 consecutive trading days of the quarter, holders may, in the immediate quarter following, convert all or a portion of their 2018 Notes. Based on the daily closing prices of the Company’s stock during the quarter ended September 30, 2021, holders of the remaining 2018 Notes are eligible to convert their 2018 Notes during the fourth quarter of 2021. Based on the terms of the 2018 Notes, when a conversion notice is received, the Company has the option to pay or deliver cash, shares of the Company’s common stock, or a combination thereof. Accordingly, the Company cannot be required to settle the 2018 Notes in cash and, therefore, the remaining 2018 Notes are classified as long-term debt as of September 30, 2021.

The following table presents the outstanding principal amount and carrying value of the Notes as of the dates indicated (in thousands):

(1) Total interest expense for the three and nine months ended September 30, 2021 consisted of coupon interest and amortization of debt issuance costs, as there is no amortization of the debt discount in the current year due to the adoption of ASU 2020-06 as of January 1, 2021, as described in “Note 1—Basis of Presentation and Summary of Significant Accounting Policies—Recently Adopted Accounting Pronouncements.”

The estimated fair value of each of the Notes was determined through inputs that are observable in the market, and are classified as Level 2. See “Note 6—Fair Value Measurements” for more information regarding the fair value of the Notes.

The Notes are general unsecured obligations of the Company. The Notes rank senior in right of payment to all of the Company’s future indebtedness that is expressly subordinated in right of payment to the Notes; rank equal in right of payment with all of the Company’s liabilities that are not so subordinated; are effectively junior to any of the Company’s secured indebtedness; and are structurally junior to all indebtedness and liabilities (including trade payables) of the Company’s subsidiaries.

2019 Credit Agreement

On February 25, 2019, the Company entered into a $200.0 million senior secured revolving credit facility pursuant to a Credit Agreement (the “2019 Credit Agreement”) with lenders party thereto from time to time, and Citibank N.A., as administrative Agent. The 2019 Credit Agreement will mature in February 2024. The 2019 Credit Agreement includes a letter of credit sublimit of $30.0 million and a swingline loan sublimit of $10.0 million.

Borrowings under the 2019 Credit Agreement (other than swingline loans) bear interest, at the Company’s option, at (i) a base rate equal to the highest of (a) the prime rate, (b) the federal funds rate plus 0.50%, and (c) an adjusted LIBOR rate for a one-month interest period plus 1.00%, in each case plus a margin ranging from 0.25% to 0.875% or (ii) an adjusted LIBOR rate plus a margin ranging from 1.25% to 1.875%. Swingline loans under the 2019 Credit Agreement bear interest at the same base rate (plus the margin applicable to borrowings bearing interest at the base rate). These margins are determined based on the senior secured net leverage ratio (defined as secured funded debt, net of unrestricted cash up to $100 million, to EBITDA) for the 12-month period consisting of the preceding four fiscal quarter periods. The Company is also obligated to pay other customary fees for a credit facility of this size and type, including an unused commitment fee, ranging from 0.20% to 0.35% depending on the Company’s senior secured net leverage ratio, and fees associated with letters of credit.

In June 2021, the Company issued the 2021 Notes, see “Note 8—Debt” for more information. Additionally, in June 2021 the Company entered into a 5-year contractual commitment for cloud-based services with an aggregate future minimum payment obligation of $525.0 million, which includes escalating commitments each contract year. Commitments did not materially change during the nine months ended September 30, 2021 except for this activity.

Legal Proceedings

From time to time in the normal course of business, various other claims and litigation have been asserted or commenced against the Company. Due to uncertainties inherent in litigation and other claims, the Company can give no assurance that it will prevail in any such matters, which could subject the Company to significant liability for damages. Any claims or litigation could have an adverse effect on the Company’s results of operations, cash flows, or business and financial condition in the period the claims or litigation are resolved. Although the results of litigation and claims cannot be predicted with certainty, the Company currently believes that the final outcome of these ordinary course matters will not have a material adverse effect on its business.

Note 10—Stockholders’ Equity

In December 2020, the Board of Directors approved a stock repurchase program that enables the Company to repurchase up to $250 million of its common stock. The program does not have a time limit and may be modified, suspended, or terminated at any time by the Board of Directors. The number of shares repurchased and the timing of repurchases will depend on a number of factors, including, but not limited to, stock price, trading volume, and general market conditions, along with Etsy’s working capital requirements, general business conditions, and other factors.

Under the stock repurchase program, the Company may purchase shares of its common stock through various means, including open market transactions, privately negotiated transactions, tender offers, or any combination thereof. In addition, open market repurchases of common stock could be made pursuant to trading plans established pursuant to Rule 10b5-1 under the Securities Exchange Act of 1934, as amended, which would permit common stock to be repurchased at a time that the Company might otherwise be precluded from doing so under insider trading laws or self-imposed trading restrictions.

In June 2021 the Company repurchased approximately 1.1 million shares of its common stock for approximately $180.0 million concurrently with the issuance of the 2021 Notes, see “Note 8—Debt.” This repurchase was separate from the stock repurchase plan approved by the Board of Directors in December 2020.

The following table summarizes the Company’s cumulative share repurchase activity under the program noted above, excluding shares withheld to satisfy tax withholding obligations in connection with the vesting of employee RSUs and excluding the 1.1 million shares repurchased in June 2021 (in thousands, except share and per share amounts):

Note 11—Stock-Based Compensation

During the three and nine months ended September 30, 2021, the Company granted stock options and RSUs, including Financial PBRSUs and TSR PBRSUs, under its 2015 Equity Incentive Plan (“2015 Plan”) and, pursuant to the evergreen increase provision of the 2015 Plan, 6,291,797 additional shares were added to the total number of shares available for issuance under the 2015 Plan effective as of January 4, 2021. At September 30, 2021, 44,040,744 shares were authorized under the 2015 Plan and 29,533,786 shares were available for future grant.

Starting in the second quarter of 2021, the Company updated certain assumptions used to determine the fair value of its stock options under the Black-Scholes option-pricing model, including the expected volatility and expected term assumptions. Given Etsy’s sufficient trading history as of the second quarter of 2021, the Company calculates expected volatility based solely on the historical volatility of Etsy’s stock price observations over a period equivalent to the expected term of the stock option grants. Prior to the second quarter of 2021, the Company estimated expected volatility by taking the average historical price volatility for Etsy and certain industry peers. Further, given that the Company has sufficient historical exercise data to provide a reasonable basis upon which to estimate the expected term of its stock options, beginning in the second quarter, the Company estimates its expected term using historical option exercise behavior and expected post-vest cancellation data, averaged with an assumption that recently granted options will be exercised ratably from vesting to the expiration of the stock option. Prior to the second quarter of 2021, the Company used the simplified method to calculate the expected term for awards issued to employees or members of the Company’s Board of Directors. These updated assumptions have been applied prospectively to option awards granted in or after the second quarter of 2021. The Company does not expect these changes to have a material impact on the Consolidated Statements of Operations.

The fair value of options granted in the periods presented below using the Black-Scholes pricing model has been based on the following assumptions:

	Three Months Ended   September 30,		Nine Months Ended   September 30,
	2021	2020	2021	2020
Volatility	56.0%	41.7%	43.4% - 56.1%	38.9% - 41.7%
Risk-free interest rate	0.9%	0.3%	0.8% - 1.1%	0.3% - 1.7%
Expected term (in years)	5.12	6.12 - 6.16	4.86 - 6.15	5.52 - 6.16

The following table summarizes the activity for the Company’s options during the nine months ended September 30, 2021 (in thousands, except share and per share amounts):

	Shares	Weighted-Average Exercise Price		Weighted-Average Remaining Contract Term (in years)	Aggregate Intrinsic Value
Outstanding at December 31, 2020	5,099,952	$	20.97	6.81	$	800,453

Notes to Consolidated Financial Statements

The total unrecognized compensation expense at September 30, 2021 related to the Company’s options was $27.9 million, which will be recognized over an estimated weighted-average amortization period of 2.84 years.

Service-based RSUs and, beginning in the first quarter of 2021, Financial PBRSUs and TSR PBRSUs, are awarded at fixed dollar amounts. The target number of shares underlying the awards is determined based on Etsy’s 30-day average share price leading up to and including the grant date.

For the Financial PBRSUs, the number of RSUs received will depend on the achievement of financial metrics relative to the approved performance targets. Depending on the actual financial metrics achieved relative to the target financial metrics, throughout the defined performance period of the award, the number of PBRSUs that vest could range from 0% to 200% of the target amount, and are subject to the Compensation Committee’s approval of the level of achievement against the approved performance targets. For the TSR PBRSUs, the number of RSUs received will depend on the Company’s total shareholder return relative to that of the Nasdaq Composite Index over a three-year measurement period.

In connection with the acquisitions of Depop and Elo7 in July 2021, outstanding, unvested options held by continuing employees of each acquired entity as of the respective acquisition dates were replaced with Etsy RSU awards with the same aggregate fair value, with a total dollar value of $78.8 million, $5.6 million of which relates to pre-combination service and was included as a component of the purchase price. These RSUs generally follow the original vesting schedule of the replaced options, which provided that they will vest 25% on the first anniversary of their original vesting commencement date with the remaining 75% vesting ratably each month thereafter until the fourth anniversary of their original vesting commencement date.

The following table summarizes the activity for the Company’s unvested RSUs, which includes Financial PBRSUs and TSR PBRSUs, during the nine months ended September 30, 2021:

	Shares	Weighted-Average Grant Date Fair Value
Unvested at December 31, 2020	3,085,987	$	50.28
Granted (1)	1,984,463	207.28
Vested	(864,588)	48.06
Forfeited/Canceled	(218,795)	86.94
Unvested at September 30, 2021	3,987,067	126.90

(1)Includes RSU awards issued to Depop and Elo7 employees in connection with the acquisitions in the third quarter of 2021.

The total unrecognized compensation expense at September 30, 2021 related to the Company’s unvested RSUs, including the Financial PBRSUs and TSR PBRSUs, was $449.2 million, which will be recognized over an estimated weighted-average amortization period of 3.11 years.

In connection with the acquisition of Depop, certain Depop executives are eligible to receive deferred consideration of $44.0 million in Etsy shares over the three years following the acquisition date, subject to certain service-based vesting conditions during the vesting period. These awards will be settled by issuing Etsy shares on or shortly following the applicable vesting date, with the number of shares to be determined based on the Company’s stock price on the applicable vesting date, and will therefore be recognized as post-combination service stock-based compensation expense over a three-year vesting period, with a corresponding liability included within Other liabilities on the Company’s Consolidated Balance Sheets until the service-based vesting criteria are met and the awards are settled in Etsy shares. The unrecognized compensation expense at September 30, 2021 related to these awards was $40.8 million, which will be recognized over a remaining term of 2.78 years. These amounts are excluded from the unrecognized compensation expense associated with the Company’s unvested RSUs noted above.

Note 12—Subsequent Event

In October 2021, the Company entered into a First Amendment to Lease (the "First Amendment") related to the Company's corporate headquarters located at 117 Adams Street and 55 Prospect Street, Brooklyn, NY. The First Amendment extends the expiration of the term of the current lease from July 31, 2026 to July 31, 2039 with an incremental future minimum payment obligation of approximately $163 million, $38 million of which relates to payments under the Company’s operating lease commitments, and $125 million of which relates to payments under the Company’s finance lease commitments. This aggregate increase to the Company’s minimum payment obligations includes a tenant allowance, a portion of which becomes available beginning in April 2022, rent concessions that become available in 2026, and escalating commitments each contract year between 2028 and 2038. The First Amendment is expected to result in increases to the Company’s right of use assets and lease liabilities related to the Company's operating and finance leases, which will result in the following changes within the Company's Consolidated Balance Sheets (in thousands):

Property, plant and equipment, net	$	66,413
Other assets	20,391
Finance lease obligations—current portion	(3,823)

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

You should read the following discussion and analysis of our financial condition and results of operations together with our consolidated financial statements and related notes and other financial information included elsewhere in this Quarterly Report on Form 10-Q (“Quarterly Report”) and with the audited consolidated financial statements included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission (“SEC”) on February 26, 2021 (the “Annual Report”). This discussion, particularly information with respect to our outlook, key trends and uncertainties, our plans and strategy for our business, and our performance and future success, includes forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those discussed below. Factors that could cause or contribute to these differences include those discussed below and elsewhere in this Quarterly Report, particularly in Part II, Item 1A, “Risk Factors.” For more information regarding key factors affecting our performance, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Key Factors Affecting our Performance” in our Annual Report, which we incorporate by reference.

Overview

Business

Etsy, Inc., founded in 2005 and headquartered in Brooklyn, NY, operates a “House of Brands,” two-sided online marketplaces that connect millions of passionate and creative buyers and sellers around the world. These marketplaces share a mission to “Keep Commerce Human,” and we’re committed to using the power of business to strengthen communities and empower people. Our primary marketplace, Etsy.com, is the global destination for unique and creative goods. Buyers come to Etsy to be inspired and delighted by items that are crafted and curated by creative entrepreneurs. For sellers, we offer a range of tools and services that address key business needs.

Alongside our core Etsy marketplace, our “House of Brands” consists of Reverb Holdings, Inc. (“Reverb”), our musical instrument marketplace, and our recent acquisitions in July 2021 — Depop Limited (“Depop”), our fashion resale marketplace, and Elo7 Serviços de Informática S.A. (“Elo7”), the Brazil-based marketplace for handmade and unique items. Each of our marketplaces operates independently, while benefiting from shared expertise in product, marketing, technology, and customer support.

Reverb is included in all financial and other metrics discussed in this report, unless otherwise noted. The results of Elo7 and Depop, acquired on July 2, 2021 and July 12, 2021, respectively, are included in all financial and other metrics discussed in this report from their respective dates of acquisition, unless otherwise noted.

The Etsy marketplace connects creative artisans and entrepreneurs with thoughtful consumers looking for items that are intended to be special, reflect their sense of style, or represent a meaningful occasion. Our sellers are the heart and soul of Etsy, and our technology platform allows our sellers to turn their creative passions into economic opportunity. We have a seller-aligned business model: we make money when our sellers make money. We offer Etsy.com sellers a marketplace with millions of buyers along with a range of seller tools and services that are specifically designed to help our creative entrepreneurs generate more sales and scale their businesses.

We are focused on attracting potential buyers to the Etsy marketplace for everyday items that have meaning and those “special” purchase occasions that happen throughout the year. We are focused on deepening our engagement with our existing buyers by inspiring purchases across our many retail categories and special occasions. Purchases for use in the everyday include handmade or vintage clothing, accessories, household items, or furniture that the buyer wants to reflect her sense of style. Special purchase occasions can occur many times throughout the year and include shopping for occasions that reflects an individual’s unique style; gifting that demonstrates thought and care; and celebrations that express creativity and fun. Buyers tell us that they come to Etsy.com because Etsy sellers offer items that they can’t find anywhere else.

Table of Contents

Our revenue is diversified, generated from a mix of marketplace activities and other optional services we provide to sellers.

Marketplace revenue is comprised of the fees a seller pays us for marketplace activities. Marketplace activities primarily include listing an item for sale; completing transactions between a buyer and a seller, which includes, beginning in the second quarter of 2020, an additional transaction fee related to offsite advertising; and using our payments services to process payments, including foreign currency transactions. Etsy.com fees include the $0.20 listing fee for each item listed (for up to four months); the 5% transaction fee that an Etsy seller pays for each completed transaction, inclusive of shipping fees charged; where applicable, an additional transaction fee of 12% or 15% related to offsite advertising; and fees for Etsy Payments, our payment processing product.

Services revenue is comprised of the fees a seller pays us for our optional other services (“Services”). Services primarily include on-site advertising services, which allow sellers to pay for prominent placement of their listings in search results; and shipping labels, which allow Etsy.com sellers in the United States, Canada, United Kingdom, Australia, and, commencing in the second quarter of 2021, India to purchase discounted shipping labels.

Our primary strategy is focused on growing the Etsy marketplace in our seven core geographies and building a sustainable competitive advantage around four elements of our business that we believe differentiate us from our competitors, or what we call our “Right to Win.” The foundation of Etsy’s competitive advantage is our collection of our sellers’ unique items, which, we believe, when combined with best-in-class search and discovery, human connections, and a trusted brand, will enable us to continue to stand out among other e-commerce platforms and marketplaces. Our investments in product, marketing, and talent will be focused on capitalizing on these four elements of our business. Ultimately, the goal of our long-term strategy is to drive more new buyers to the Etsy marketplace, give existing buyers reasons to come back more often, encourage buyers to spend more per order, and fuel success for our sellers. While current macroeconomic conditions have had a dramatic effect on the global economy and on our business, these impacts have led us to reaffirm and strengthen our commitment to our long-term strategy.

We see a number of similarities between the levers of growth for Etsy and for our acquired marketplaces, Reverb (in July 2019), Depop (in July 2021), and Elo7 (in July 2021). These include improving search and discovery, making selling and buying easier, and building global brands and user communities.

Third Quarter 2021 Financial Highlights

As of September 30, 2021, our marketplaces connected 7.5 million active sellers and 96.0 million active buyers in nearly every country in the world. In the three and nine months ended September 30, 2021, sellers generated GMS of $3.1 billion and $9.3 billion, respectively, of which approximately 64% in each period came from purchases made on mobile devices. We are a global company and approximately 42% of our GMS in both the three and nine months ended September 30, 2021 came from transactions where either a seller or a buyer was located outside of the United States.

Total revenue was $532.4 million and $1.6 billion in the three and nine months ended September 30, 2021, respectively, driven by strong growth in both Marketplace and Services revenue. In the three and nine months ended September 30, 2021, we recorded net income of $89.9 million and $332.0 million, respectively, and non-GAAP Adjusted EBITDA of $174.2 million and $497.8 million, respectively. See “Non-GAAP Financial Measures” for more information and for a reconciliation of Adjusted EBITDA to net income, the most directly comparable financial measure calculated in accordance with GAAP.

Cash, cash equivalents, and short-term investments were $816.8 million as of September 30, 2021. As of September 30, 2021, we had outstanding $1.0 billion aggregate principal amount of 0.25% Convertible Senior Notes due 2028 (the “2021 Notes”), $650.0 million aggregate principal amount of 0.125% Convertible Senior Notes due 2027 (the “2020 Notes”), $650.0 million aggregate principal amount of 0.125% Convertible Senior Notes due 2026 (the “2019 Notes”), and $0.1 million aggregate principal amount of 0% Convertible Senior Notes due 2023 (the “2018 Notes” and together with the 2021 Notes, 2020 Notes, and the 2019 Notes, the “Notes”). Additionally, we have the ability to draw down on our $200.0 million senior secured revolving credit facility. In the nine months ended September 30, 2021, we had positive operating cash flows of $361.1 million.

Acquisitions

On July 2, 2021, we completed our acquisition of Elo7, a top 10 e-commerce marketplace in Brazil focused on unique, handmade items for consideration having fair value of approximately $212 million, net of cash acquired, after giving effect to purchase price adjustments. We see significant potential in Brazil's e-commerce sector, which is still in early stages of development and fueled by one of the largest economies in the world. We believe having a well-known local brand will help Etsy, Inc. to better capitalize on this opportunity.

On July 12, 2021, we completed our acquisition of Depop, an online global peer-to-peer fashion resale marketplace for consideration having fair value of approximately $1.493 billion, net of cash acquired, after giving effect to purchase price adjustments. We believe Depop extends our market opportunity in the high frequency apparel sector, specifically in the fast-growing resale space, and deepens our reach into the Gen Z consumer demographic.

Convertible Debt

In June 2021, we issued the 2021 Notes in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”). The initial conversion price of the 2021 Notes represented a premium of approximately 45% over the closing price of our common stock on June 8, 2021, the date the 2021 Notes offering was priced. The net proceeds from the sale of the 2021 Notes were $986.7 million after deducting the offering expenses. The 2021 Notes will mature on June 15, 2028, unless earlier converted, redeemed, or repurchased.

We used $85.0 million of the net proceeds from the 2021 Notes offering to enter into separate capped call instruments (“2021 Capped Call Transactions”) with certain financial institutions. The 2021 Capped Call Transactions effectively limit the premium for conversion of the 2021 Notes to 100% and are generally expected to reduce potential dilution to our common stock upon any conversion of the 2021 Notes and/or offset any payments we make upon conversion.

In addition, we repurchased approximately 1.1 million shares of our common stock for approximately $180.0 million concurrently with the issuance of the 2021 Notes.

We intend to use the remainder of the net proceeds from the 2021 Notes for general corporate purposes. For more information on the 2021 Notes and 2021 Capped Call Transactions, see “Note 8—Debt” in the Notes to Consolidated Financial Statements.

Quarterly Operating Highlights

Select highlights of our third quarter operating performance and business initiatives are outlined below:

Product: Our primary focus in 2021 is to improve customer experiences across the Etsy marketplace to engage and retain the millions of buyers that we acquired over the past year. These are just a few of our initiatives during the third quarter, aligned with our Right to Win strategy.

•Leveraging XWalk, our large-scale, real-time graph retrieval engine, we’re continuing to narrow the semantic gap by relying less on listing taxonomy and more on buyer interests. Additionally, during the quarter we incorporated datasets with buyer hobbies and mapped them to Etsy listings to deliver more relevant inventory and improve conversion rate for recommendations. We’re also utilizing machine learning to enable real-time personalization that better understands buyers’ needs while they shop.

•We launched “The Etsy House,” our first-ever interactive, augmented-reality feature that allows buyers to shop a digital home filled with curated items. This is an innovative way to showcase the quality and breadth of sellers’ merchandise.

•We made substantial improvements to delivery transparency ahead of the holiday season: nearly 100% of U.S. listings now include expected delivery date and origin zip code information.

•Our launch of Etsy’s Star Seller program, which defines what success looks like by celebrating and rewarding our top-rated sellers, defining standards, and giving them motivation, support, and agency to improve their Etsy businesses, has improved several customer service metrics critical to the Etsy platform, such as on-time shipping and responsiveness. Also, early signals indicate that purchasing from a Star Seller may increase buyer frequency, with Star Sellers generating higher repeat purchase rates than those who have yet to achieve the badge. We also recently launched a preview version of our new Sell on Etsy App, which is trending positively in seller engagement.

•We’ve focused on transitioning buyers to our Buy on Etsy app, which we believe is the best way to transact on Etsy; personalizing the on-boarding experience and helping buyers discover items and shops that align with their tastes and preferences. As a result, during the quarter the app surpassed mobile web in GMS share for the first time ever, and we saw a 36% year-to-date increase in app downloads - ranking the Etsy app the fifth most downloaded in the Apple Store.

Marketing: We continued to optimize spend across our marketing channels, with particular focus on increasing the percentage of spend to upper and mid-funnel, and launching creative new marketing campaigns that target frequency improvements.

•Brand marketing for the Etsy marketplace continues to be a significant focus, with spend at 15% of our total marketing expense in the third quarter, or approximately $19 million. In the U.S., our brand metrics remained stable sequentially with noticeably improved visit intent and recommendation when compared to this time last year.

•Examples of new or expanded marketing initiatives include:

◦Introduction of male-targeted ad campaigns in the United States and testing of out-of-home advertising in the United Kingdom;

◦Introduction of our third “Creator Collab,” focused on supporting sellers from the LGBTQIA+ community, targeting international markets. This latest collaboration drove strong sales and delivered positive return on investment and strong international earned media; and

◦Creation of an impactful global press strategy and multi-channel activations to celebrate the winners of our third-annual Etsy Design Awards.

•For Holiday 2021, we’re reinforcing Etsy as the go-to destination to shop and gift meaningfully - launching a variety of strategic initiatives including encouraging early shopping through our Early Holiday Sales Event and targeted buyer discounting. We are also helping sellers to manage anticipated carrier delays and holiday delivery cut off dates to meet buyers’ expectations.

•We continued to invest with discipline in our performance marketing channels, testing and refining our ROI models, and continuing to optimize to marginal return efficiency. During the quarter we pulled back on performance marketing to measure the incremental performance of several channels.

Impact Pillars: We continued to make progress on our Impact strategy that reflects the positive economic, social, and ecological impact we want to have on the world while advancing and complementing our business strategy. Here are some highlights:

•We’re making progress towards reaching our pledge of being Net Zero by 2030. We’re offering U.S. sellers planet-friendly packaging options to help reduce Scope 3 greenhouse emissions and build buyer awareness of Etsy as a sustainable place to shop.

•Our Uplift Makers program has supported the launch of almost 40 shops representing heritage craft makers from across the Southern United States. In its first six months, the Gee’s Bend quilting community generated more than $300,000 in sales through their Etsy shops. We are now aiming to replicate that success for the recently launched shops of the Gullah basket weavers, a community in South Carolina known for their unique basket-weaving techniques.

Lastly, we are on track with our work integrating Depop and Elo7 into Etsy, Inc., and developing focused investment plans designed to deliver value creation across our businesses. In particular, we see opportunities to capitalize on Etsy’s experience driving the growth of two-sided marketplaces with similar product and marketing strategies. Near term priorities for Depop include focusing on increased brand exposure, improving the customer experience and optimizing conversion rate, growing value added seller services, and expanding marketing strategies. Elo7 is focused on optimizing conversion rate through investments in search and discovery, refining marketing efficiency, and improving the buyer and seller experiences. And Reverb continues to invest in its core focus areas for 2021: increased personalization, selling more new gear, international growth, and improving the customer experience.

GMS

Gross merchandise sales (“GMS”) is the dollar value of items sold in our marketplaces within the applicable period, excluding shipping fees and net of refunds associated with canceled transactions. GMS does not represent revenue earned by us. GMS is largely driven by transactions in our marketplaces and is not directly impacted by Services activity. However, because our revenue and cost of revenue depend significantly on the dollar value of items sold in our marketplace, we believe that GMS is an indicator of the success of our sellers, the satisfaction of our buyers, and the health, scale, and growth of our business. We track “Paid GMS” for the Etsy marketplace and define it as Etsy.com GMS that is attributable to our performance marketing efforts, which excludes most of our marketing investments focused on brand awareness like TV and digital video.

GMS increased $472.0 million to $3.1 billion and increased $2.6 billion to $9.3 billion in the three and nine months ended September 30, 2021, respectively, compared to the three and nine months ended September 30, 2020, respectively. Supporting this growth in GMS was an increase in active sellers, driven by strong growth in both U.S. and international sellers on the Etsy.com marketplace, an increase in active buyers on the Etsy.com marketplace as compared to September 30, 2020, and the acquisitions of Depop and Elo7 in the third quarter of 2021. As of September 30, 2021, habitual buyers, or Etsy.com buyers who have spent $200 or more and made purchases on six or more days in the previous 12 months, grew to 8.0 million, an increase of 65% compared to September 30, 2020. Additionally, we experienced the following (decline)/growth in both new buyer and existing buyer GMS in the periods presented:

	Three Months Ended   September 30,
	2021				2020
	% (Decline) Growth Y/Y		% of GMS		% Growth Y/Y		% of GMS
New Buyer GMS	(8)	%	12	%	117	%	16	%
Existing Buyer GMS	23	%	88	%	120	%	84	%

	% Growth Y/Y		% of GMS		% Growth Y/Y		% of GMS
New Buyer GMS	13	%	14	%	102	%	17	%
Existing Buyer GMS	44	%	86	%	101	%	83	%

It is difficult to predict how our business will be impacted as the ongoing COVID-19 pandemic, including recent and any future variants, runs its course and eventually abates. Our growth rate decelerated in the third quarter of 2021 as compared to the extraordinary growth experienced one year ago driven by the shift of global consumers to purchase online. Our growth rate may continue to decrease as compared to the significant growth experienced in the fourth quarter of 2020 and early 2021 due to a combination of reasons including: macroeconomic factors such as retail businesses reopening, increased consumer spending on travel and other discretionary items, the waning impact of U.S. and other government economic stimulus programs, continued contraction of mask sales, and a deceleration of new buyers, as anticipated, which may be offset to some extent by incremental GMS from our recent acquisitions.

Adjusted EBITDA and Adjusted EBITDA Margin

Adjusted EBITDA represents our net income adjusted to exclude: interest and other non-operating expense, net; (benefit) provision for income taxes; depreciation and amortization; stock-based compensation expense; foreign exchange (gain) loss; acquisition-related expenses; and loss on extinguishment of debt. Adjusted EBITDA margin is Adjusted EBITDA divided by revenue. See “Non-GAAP Financial Measures” for more information regarding our use of Adjusted EBITDA and Adjusted EBITDA margin, including their limitations as a financial measure, and for a reconciliation of Adjusted EBITDA to net income, the most directly comparable GAAP financial measure.

Active Sellers

An active seller is a seller who has had a charge or sale in the last 12 months. Charges include Marketplace and Services revenue fees, discussed in “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Overview—Business.” A seller is separately identified in each of our marketplaces by a unique e-mail address; a single person can have multiple seller accounts and can count as a distinct active seller in each of our marketplaces. As part of our commitment to integrity and transparency, we continuously monitor the criteria for disqualifying a seller as an active seller. Commencing in the first quarter of 2021, we expanded our disqualifying criteria, but did not apply such criteria to prior periods as the impact of such criteria was immaterial to such periods. Additionally, commencing in the third quarter of 2021, as part of our integration of the Depop and Elo7 marketplaces into our “House of Brands,” we expanded our definition of active sellers to include any seller who has had a sale in the last 12 months, even if no charge was incurred in connection with the sale. This update did not result in any change to prior period disclosures. We succeed when sellers succeed, so we view the number of active sellers as a key indicator

of the awareness of our brand, the reach of our platform, the potential for growth in GMS and revenue, and the health of our business.

Active Buyers

An active buyer is a buyer who has made at least one purchase in the last 12 months. A buyer is separately identified in each of our marketplaces by a unique e-mail address; a single person can have multiple buyer accounts and can count as a distinct active buyer in each of our marketplaces. We generate revenue when buyers order items from sellers, so we view the number of active buyers as a key indicator of our potential for growth in GMS and revenue, the reach of our platform, awareness of our brand, the engagement and loyalty of buyers, and the health of our business.

Mobile GMS

Mobile GMS is GMS that results from a transaction completed on a mobile device, such as a tablet or a smartphone. Mobile GMS excludes orders initiated on mobile devices but ultimately completed on a desktop. When calculating the percentage of mobile GMS, we do not take into account refunds associated with canceled transactions. We believe that mobile GMS indicates our success in converting mobile activity into mobile purchases and demonstrates our ability to grow GMS and revenue.

During both the three and nine months ended September 30, 2021, mobile GMS increased as a percentage of total GMS to approximately 64%, up from approximately 62% and 61% for the three and nine months ended September 30, 2020, respectively.

Non-U.S. GMS

Non-U.S. GMS (formerly referred to as international GMS) is GMS from transactions where either the billing address for the seller or the shipping address for the buyer at the time of sale is outside of the United States. When calculating percent non-U.S. GMS, we do not take into account refunds associated with canceled transactions. We believe that non-U.S. GMS shows the level of engagement of our community outside the United States and demonstrates our ability to grow GMS and revenue.

For both the three and nine months ended September 30, 2021, non-U.S. GMS increased as a percentage of total GMS to approximately 42%, up from approximately 35% and 34% for the three and nine months ended September 30, 2020, respectively. Non-U.S. GMS increased approximately 42% and 70%, respectively, in the three and nine months ended September 30, 2021 compared to the three and nine months ended September 30, 2020, respectively, or 29% and 59%, respectively, on a currency-neutral basis, driven by our fastest growing non-U.S. trade route, non-U.S. domestic, which is GMS generated between a non-U.S. buyer and a non-U.S. seller both in the same country. Non-U.S. domestic GMS grew approximately 70% and 104%, respectively, in the three and nine months ended September 30, 2021 compared with the three and nine months ended September 30, 2020, respectively, driven in part by our acquisitions of Depop and Elo7 in the third quarter of 2021.

Currency-Neutral GMS Growth

We calculate currency-neutral GMS growth by translating current period GMS for goods sold that were listed in non-U.S. dollar currencies into U.S. dollars using prior year foreign currency exchange rates.

As reported and currency-neutral GMS growth for the periods presented below is as follows:

	Quarter-to-Date Period Ended						Year-to-Date Period Ended
	As Reported		Currency-Neutral		FX Impact		As Reported		Currency-Neutral		FX Impact
September 30, 2021 (1)	17.9	%	16.6	%	1.3	%	39.2	%	36.5	%	2.7	%
June 30, 2021	13.1	%	10.2	%	2.9	%	53.0	%	49.5	%	3.5	%
March 31, 2021	132.3	%	127.5	%	4.8	%	132.3	%	127.5	%	4.8	%

Percentage of total revenue	25.7		%	24.3		%
Total revenue	$	532,429		$	451,478		$	80,951	17.9	%

Revenue increased $81.0 million to $532.4 million in the three months ended September 30, 2021 compared to the three months ended September 30, 2020, of which 74.3% consisted of Marketplace revenue and 25.7% consisted of Services revenue.

Marketplace revenue increased $53.9 million to $395.5 million in the three months ended September 30, 2021 compared to the three months ended September 30, 2020. This growth was substantially all due to an increase in the volume of GMS for the three months ended September 30, 2021 to a total of $3.1 billion. A significant majority of the growth in volume of GMS was driven by the Etsy marketplace. The balance was primarily due to the acquisitions of Depop and Elo7 in the third quarter of 2021. Marketplace revenue also increased due to Reverb, whose revenue consisted principally of Marketplace revenue.

Within the increase in volume of GMS, transaction fee revenue increased 18.2%, payments revenue grew 13.0%, and listing fee revenue increased 12.5% year-over-year. The share of Etsy.com GMS processed through our Etsy Payments platform was 91% in the three months ended September 30, 2021, down from 92% in the three months ended September 30, 2020.

Services revenue increased $27.1 million to $136.9 million in the three months ended September 30, 2021 compared to the three months ended September 30, 2020. The growth in Services revenue was primarily driven by an increase of 27.9% in on-site advertising revenue (primarily through our renamed Etsy Ads product), mainly due to higher click volume.

Cost of Revenue

Cost of revenue	$	153,660		$	120,168		$	33,492	27.9	%

Cost of revenue increased $33.5 million to $153.7 million in the three months ended September 30, 2021 compared to the three months ended September 30, 2020. The increase was primarily driven by increased costs related to overall volume increases on our Etsy and Reverb marketplaces, including payments fees and cloud-related hosting and bandwidth costs. The increase was also due to the cost of revenue associated with the Depop and Elo7 acquisitions, including employee compensation-related expenses and the amortization of developed technology, and, to a lesser extent, an increase in outsourced customer support expenses.

Operating Expenses

We had 2,338 total employees on September 30, 2021, compared with 1,374 total employees on September 30, 2020 and 1,414 on December 31, 2020. We expect an increase in employee compensation-related expenses, including stock-based compensation, in the fourth quarter of 2021 and future periods driven by headcount growth, including headcount increases related to the acquisitions of Depop and Elo7.

Marketing

Marketing	$	131,928		$	126,779		$	5,149	4.1	%

Marketing expenses increased $5.1 million to $131.9 million in the three months ended September 30, 2021 compared to the three months ended September 30, 2020. The increase was primarily a result of the acquisitions of Depop and Elo7, including the amortization of acquired intangible assets and employee compensation-related expenses. Marketing expenses increased to a lesser extent due to increased employee compensation-related expenses, including stock-based compensation, for Etsy.com and Reverb employees, mainly driven by an increase in average headcount. These increases were partially offset by decreases in both digital and non-digital marketing expenses, which were lower due to testing and optimization and lower spend on television ad campaigns. Our Paid GMS share also decreased to 17% of overall GMS in the three months ended September 30, 2021, compared to 19% in the three months ended September 30, 2020, driven by lower paid marketing expense.

Product development expenses increased $27.6 million to $73.5 million in the three months ended September 30, 2021 compared to the three months ended September 30, 2020. The increase was primarily a result of increased employee compensation-related expenses, including stock-based compensation, mainly driven by an increase in average headcount, including headcount related to the acquisitions of Depop and Elo7.

General and administrative expenses increased $49.1 million to $89.6 million in the three months ended September 30, 2021 compared to the three months ended September 30, 2020. The increase was primarily due to acquisition-related expenses associated with the Depop and Elo7 acquisitions, which closed in July 2021. For more information on acquisition-related expenses see “Note 5—Business Combinations” in the Notes to Consolidated Financial Statements. General and administrative expenses increased to a lesser extent due to employee compensation-related expenses, including stock-based compensation. The increase in employee compensation-related expenses was mainly driven by an increase in average headcount, including headcount related to the acquisitions of Depop and Elo7, and performance based restricted stock units, which were granted for the first time in 2021.

Other income, net was $0.1 million in the three months ended September 30, 2021, which increased $27.8 million from a $27.8 million expense in the three months ended September 30, 2020. The decrease in expense was primarily driven by a non-cash loss on extinguishment of debt of $16.9 million related to the partial repurchase of the 2018 Notes in the third quarter of 2020. In addition, the decrease was driven by a decrease in interest expense as a result of the adoption of Accounting Standards Update (“ASU”) 2020-06 in the first quarter of 2021 which resulted in no further amortization of the debt discount related to the Notes due to its derecognition. For more information on the adoption of ASU 2020-06, see “Note 1—Basis of Presentation and Summary of Significant Accounting Policies—Recently Adopted Accounting Pronouncements” in the Notes to Consolidated Financial Statements.

Our income tax benefit for the three months ended September 30, 2021 and 2020 was $6.1 million and $1.4 million, respectively.

The primary drivers of our income tax benefit for the three months ended September 30, 2021 were tax benefits from employee stock-based compensation of $9.2 million and a benefit related to research and development tax credits of $7.1 million, partially offset by tax expense of $6.3 million on income before income taxes and a $3.1 million tax impact from non-deductible transaction costs.

The primary drivers of our income tax benefit for the three months ended September 30, 2020 were excess tax benefits from employee stock-based compensation of $13.4 million and a benefit related to research and development tax credit of $7.5 million, partially offset by tax expense of $15.7 million on income before income taxes and U.S. taxes on foreign earnings of $2.8 million.

Total revenue	$	1,611,975		$	1,108,270		$	503,705	45.4	%

Revenue increased $503.7 million to $1.6 billion in the nine months ended September 30, 2021 compared to the nine months ended September 30, 2020, of which 74.7% consisted of Marketplace revenue and 25.3% consisted of Services revenue.

Marketplace revenue increased $375.0 million to $1.2 billion in the nine months ended September 30, 2021 compared to the nine months ended September 30, 2020. This growth was substantially all due to an increase in the volume of GMS for the nine months ended September 30, 2021 to a total of $9.3 billion, and the balance was due to pricing related to our Offsite Ads transaction fee, which was introduced in May 2020. A significant majority of the growth in volume of GMS was driven by the Etsy marketplace. The balance was primarily due to Reverb, whose revenue consisted principally of Marketplace revenue, and, to a lesser extent, due to the acquisitions of Depop and Elo7 in the third quarter of 2021.

Within the increase in volume of GMS, transaction fee revenue increased 43.9%, payments revenue increased 43.2%, and listing fee revenue increased 30.2% year-over-year. The share of Etsy.com GMS processed through our Etsy Payments platform was 92% for both the nine months ended September 30, 2021 and 2020.

Services revenue increased $128.7 million to $407.4 million in the nine months ended September 30, 2021 compared to the nine months ended September 30, 2020. The growth in Services revenue was primarily driven by an increase of 50.3% in on-site advertising revenue, which represented a significant majority of the overall Services revenue increase, and, to a lesser extent, an increase in shipping label revenue of 23.1% from the prior year. The increase in advertising revenue was primarily due to higher click volume on Etsy Ads. The increase in shipping label revenue was primarily driven by an increase in label volume, the majority of which was driven by the increase in GMS.

Cost of revenue increased $131.6 million to $445.5 million in the nine months ended September 30, 2021 compared to the nine months ended September 30, 2020, primarily driven by increased costs related to overall volume increases on our Etsy and Reverb marketplaces, including payments fees and cloud-related hosting and bandwidth costs. The increase was also due to increased employee compensation-related expenses, including stock-based compensation, mainly driven by an increase in average headcount. Cost of revenue increased to a lesser extent due to the cost of revenue associated with the Depop and Elo7 acquisitions, including employee compensation-related expenses and the amortization of developed technology. Additionally, outsourced customer support expenses increased.

Marketing	$	450,606		$	289,991		$	160,615	55.4	%

Marketing expenses increased $160.6 million to $450.6 million in the nine months ended September 30, 2021 compared to the nine months ended September 30, 2020, primarily as a result of increased spend in digital marketing, and, to a lesser extent, television ad campaigns. The increase in digital marketing expense was largely due to the shift to our Offsite Ads offering beginning in May 2020 and increased site traffic. Paid GMS was 19% of overall GMS in both the nine months ended September 30, 2021 and 2020. The acquisitions of Depop and Elo7, including the amortization of acquired intangible assets and employee compensation-related expenses, also contributed to the increase.

Product development expenses increased $60.1 million to $189.0 million in the nine months ended September 30, 2021 compared to the nine months ended September 30, 2020, primarily as a result of increased employee compensation-related expenses, including stock-based compensation, mainly driven by an increase in average headcount, an increase in expenses for third-party contractors and consultants, and, to a lesser extent, the acquisitions of Depop and Elo7.

General and administrative expenses increased $90.6 million to $203.4 million in the nine months ended September 30, 2021 compared to the nine months ended September 30, 2020, primarily due to acquisition-related expenses associated with the Depop and Elo7 acquisitions, which closed in July 2021. For more information on acquisition-related expenses see “Note 5—Business Combinations” in the Notes to Consolidated Financial Statements. Additionally, general and administrative expenses increased due to increased employee compensation-related expenses, including stock-based compensation, mainly driven by an increase in average headcount and performance based restricted stock units, which were granted for the first time in 2021. General and administrative expenses increased to a lesser extent due to employee compensation-related expenses associated with the acquisitions of Depop and Elo7 and increased digital service tax expenses, driven by business growth.

Other income, net was $3.8 million in the nine months ended September 30, 2021, which increased $54.1 million from other expense, net of $50.3 million in the nine months ended September 30, 2020. The increase was primarily driven by a decrease in interest expense as a result of the adoption of ASU 2020-06 in the first quarter of 2021 as there was no further amortization of the debt discount related to the Notes due to its derecognition. For more information on the adoption of ASU 2020-06, see “Note 1—Basis of Presentation and Summary of Significant Accounting Policies—Recently Adopted Accounting Pronouncements” in the Notes to Consolidated Financial Statements. In addition, the increase was driven by both a non-cash loss on extinguishment of debt of $16.9 million related to the partial repurchase of the 2018 Notes in the third quarter of 2020 and by favorable changes in U.S. dollar, Euro, Pound Sterling, and Canadian dollar exchange rates in the current year versus unfavorable changes in the exchange rates for the same currencies in the prior year which impact our intercompany and other non-functional currency cash balances, resulting in a foreign exchange gain in the current period versus a foreign exchange loss in the prior period.

Our income tax benefit and provision for the nine months ended September 30, 2021 and 2020 was $4.7 million and $11.7 million, respectively.

The primary drivers of our income tax benefit for the nine months ended September 30, 2021 were tax benefits from employee stock-based compensation of $42.4 million and a benefit related to research and development tax credits of $13.5 million, partially offset by tax expense of $47.7 million on income before income taxes, and a $3.1 million tax impact from non-deductible transaction costs.

The primary driver of our income tax provision for the nine months ended September 30, 2020 was tax expense of $37.0 million on income before income taxes, partially offset by excess tax benefits from employee stock-based compensation of $23.7 million.

Non-GAAP Financial Measures

Adjusted EBITDA and Adjusted EBITDA Margin

In this Quarterly Report, we provide Adjusted EBITDA, a non-GAAP financial measure that represents our net income adjusted to exclude: interest and other non-operating expense, net; (benefit) provision for income taxes; depreciation and amortization; stock-based compensation expense; foreign exchange (gain) loss; acquisition-related expenses; and loss on extinguishment of debt. We also provide Adjusted EBITDA margin, a non-GAAP financial measure that presents Adjusted EBITDA divided by revenue. Below is a reconciliation of Adjusted EBITDA to net income, the most directly comparable GAAP financial measure.

We have included Adjusted EBITDA and Adjusted EBITDA margin because they are key measures used by our management and Board of Directors to evaluate our operating performance and trends, allocate internal resources, prepare and approve our annual budget, develop short- and long-term operating plans, determine incentive compensation, and assess the health of our business. As our Adjusted EBITDA increases, we are able to invest more in our platforms.

We believe that Adjusted EBITDA and Adjusted EBITDA margin can provide useful measures for period-to-period comparisons of our business as they remove the impact of certain non-cash items and certain variable charges.

Adjusted EBITDA and Adjusted EBITDA margin have limitations as analytical tools, and you should not consider them in isolation or as a substitute for analysis of our results as reported under GAAP. Some of these limitations are:

•Adjusted EBITDA does not reflect other non-operating expenses, net of other non-operating income, including net interest expense;

•Adjusted EBITDA does not reflect tax payments that may represent a reduction in cash available to us;

•although depreciation and amortization are non-cash charges, the assets being depreciated and amortized may have to be replaced in the future, and Adjusted EBITDA does not reflect cash capital expenditure requirements for such replacements or for new capital expenditure requirements;

•Adjusted EBITDA does not consider the impact of stock-based compensation expense;

•Adjusted EBITDA does not consider the impact of foreign exchange (gain) loss;

•Adjusted EBITDA does not reflect acquisition-related expenses;

•Adjusted EBITDA does not consider the impact of the loss on extinguishment of debt; and

•other companies, including companies in our industry, may calculate Adjusted EBITDA differently, which reduces its usefulness as a comparative measure.

Because of these limitations, you should consider Adjusted EBITDA and Adjusted EBITDA margin alongside other financial performance measures, including net income, revenue, and our other GAAP results.

The adoption of ASU 2020-06 in the first quarter of 2021 resulted in a decrease in non-cash interest expense related to the Notes as there was no amortization of the debt discount due to its derecognition.

Liquidity and Capital Resources

Cash, cash equivalents, and short-term investments were $816.8 million as of September 30, 2021. Additionally, we have $90.4 million in long-term investments that we can liquidate at short notice and with minimal penalties if needed. We also have the ability to draw down on our $200.0 million senior secured revolving credit facility. In the nine months ended September 30, 2021, we had positive operating cash flows of $361.1 million and we expect to generate additional cash flow from operations in the fourth quarter of 2021. We believe that this capital structure, as well as the nature and framework of our business will allow us to meet all debt covenants, sustain our business operations, and be able to react to changing macroeconomic conditions.

The following table shows our cash and cash equivalents, and short- and long-term investments, and net working capital as of the date indicated:

	As of September 30, 2021
	(in thousands)
Cash and cash equivalents	$	619,402
Short-term investments	197,430
Long-term investments	90,350
Total cash and cash equivalents, and short- and long-term investments	$	907,182
Net working capital	$	606,327

As of September 30, 2021, a majority of our cash and cash equivalents, which were primarily held in cash deposits and money market funds, were held in the United States for future investments, working capital funding, and general corporate purposes. We fund our international operations from our funds held in the United States on an as-needed basis.

We invest in short- and long-term instruments, including fixed-income funds and U.S. Government and agency securities aligned with our investment strategy. These investments are intended to allow us to preserve our principal, maintain the ability to meet our liquidity needs, deliver positive yields across a balanced portfolio, and continue to provide us with direct fiduciary control. In accordance with our investment policy, all investments have maturities no longer than 37 months, with the average maturity of these investments maintained at 12 months or less.

Sources of Liquidity

As of September 30, 2021 we had four outstanding series of convertible senior notes. Based on the terms of the Notes, we have the option to pay or deliver cash, shares of our common stock, or a combination thereof, when a conversion notice is received. Based on the daily closing prices of our stock during the quarter ended September 30, 2021, holders of the 2019 Notes and 2018 Notes are eligible to convert their Notes during the fourth quarter of 2021 and holders of the 2021 Notes and 2020 Notes are not eligible to convert their Notes during the fourth quarter of 2021.

During the nine months ended September 30, 2021, we paid $43.9 million in cash and issued approximately 1.0 million shares of Etsy’s common stock to settle conversion notices of $43.8 million aggregate principal amount of the outstanding 2018 Notes.

We have the ability to draw down on a $200.0 million senior secured revolving credit facility (the “2019 Credit Agreement”). At September 30, 2021, we did not have any borrowings under the 2019 Credit Agreement.

For more information on the Notes and the 2019 Credit Agreement see “Note 8—Debt” in the Notes to Consolidated Financial Statements.

We believe that our existing cash and cash equivalents and short- and long-term investments, together with cash generated from operations, will be sufficient to meet our anticipated operating cash needs for at least the next 12 months. While this belief is based on our current expectations and assumptions in light of current macroeconomic conditions, our future capital requirements and the adequacy of available funds will depend on many factors, including those described in Part II, Item 1A, “Risk Factors” in this Quarterly Report.

Historical Cash Flows

	Nine Months Ended   September 30,
	2021		2020
	(in thousands)
Cash provided by (used in):
Operating activities	$	361,092	$	435,289
Investing activities	(1,534,861)		41,643
Financing activities	558,167		220,574

Net Cash Provided by Operating Activities

Our cash flows from operations are largely dependent on the amount of revenue generated on our platforms, as well as associated cost of revenue and other operating expenses. Our primary source of cash from operating activities is cash collections from our customers. Net cash provided by operating activities in each period presented has been influenced by changes in working capital.

Net cash provided by operating activities was $361.1 million in the nine months ended September 30, 2021, primarily driven by cash net income of $404.1 million as a result of revenue generated on our platforms, and changes in our operating assets and liabilities that used $43.0 million in cash, primarily driven by timing of payment of payables in the period.

Net cash provided by operating activities was $435.3 million in the nine months ended September 30, 2020, primarily driven by cash net income of $363.8 million, as a result of revenue generated on our platforms and changes in our operating assets and liabilities that provided $71.5 million in cash, primarily driven by timing of payment of payables in the period.

Net Cash (Used in) Provided by Investing Activities

Our primary investing activities consist of cash paid in the acquisitions of Depop and Elo7, sales and purchases of short- and long-term marketable securities and capital expenditures, including investments in capitalized website development and internal-use software and purchases of property and equipment to support our overall business growth.

Net cash used in investing activities was $1.5 billion in the nine months ended September 30, 2021. This was primarily attributable to $1.7 billion in cash paid to acquire Depop and Elo7. In addition, investing activities included $17.3 million in capital expenditures, including $11.5 million for website development and internal-use software as we continued to invest in projects adding new features and functionality to our platforms. This was partially offset by net sales of marketable securities of $175.1 million.

Net cash provided by investing activities was $41.6 million in the nine months ended September 30, 2020. This was primarily attributable to net sales of marketable securities of $45.7 million. This was partially offset by $4.1 million in capital expenditures, including $3.7 million for website development and internal-use software.

Net Cash Provided by Financing Activities

Our primary financing activities include proceeds from the issuance of convertible notes, settlement of convertible senior notes, repurchases of common stock, payments related to capped call transactions, payment of tax obligations on vested equity awards, proceeds from exercise of stock options, payments of debt issuance costs, and payments on finance lease obligations.

Net cash provided by financing activities was $558.2 million in the nine months ended September 30, 2021. This was primarily attributable to proceeds from issuance of the 2021 Notes of $1.0 billion and proceeds from the exercise of stock options of $10.9 million, partially offset by stock repurchases of $234.4 million ($180.0 million in conjunction with the issuance of the 2021 Notes and $54.4 million as part of our stock repurchase program), payments of $85.0 million for the 2021 Capped Call Transactions, payment of tax obligations on vested equity awards of $69.1 million, the conversion of $43.9 million of the Notes, and payment of debt issuance costs of $12.8 million.

Net cash provided by financing activities was $220.6 million in the nine months ended September 30, 2020. This was primarily attributable to proceeds from issuance of the 2020 Notes of $650.0 million and proceeds from the exercise of stock options of $18.5 million, partially offset by stock repurchases of $191.2 million, partial repurchase of the 2018 Notes of $137.2 million, payments of $74.7 million for the 2020 Capped Call Transactions, and payment of tax obligations on vested equity awards of $19.8 million.

Off Balance Sheet Arrangements

As of September 30, 2021, we had no off balance sheet arrangements.

Contractual Obligations

In June 2021, we issued the 2021 Notes, see “Note 8—Debt” in the Notes to Consolidated Financial Statements for more information. Additionally, in June 2021 we entered into a 5-year contractual commitment for cloud-based services with an aggregate future minimum payment obligation of $525.0 million, which includes escalating commitments each contract year. As of September 30, 2021, there were no other material changes in commitments under contractual obligations, compared to the contractual obligations disclosed in our Annual Report.

Critical Accounting Policies and Estimates

Our management’s discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, equity, revenue, expenses, and related disclosures. We evaluate our estimates and assumptions on an ongoing basis. The future effects of the ongoing COVID-19 pandemic on our results of operations, cash flows, and financial position are unclear; however we believe we have used reasonable estimates and assumptions in preparing the consolidated financial statements. Our actual results could differ from these estimates.

Except for changes resulting from updates to expected volatility and expected term assumptions used to determine the fair value of our stock options under the Black-Scholes option-pricing model in the second quarter of 2021, see “Note 11—Stock-Based Compensation” in the Notes to Consolidated Financial Statements, and the issuance of performance based restricted stock units and the adoption of ASU 2020-06 during the first quarter of 2021, see “Note 1—Basis of Presentation and Summary of Significant Accounting Policies” in the Notes to Consolidated Financial Statements, there have been no significant changes to our critical accounting policies included in our Annual Report.

We acquired both Depop and Elo7 in July 2021. Determining the fair value of the assets acquired and liabilities assumed required management to use significant judgment and estimates, including estimates of future revenue, incremental after tax cash flows, discount rates, and estimated replacement costs. Our estimates of fair value were based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable. Except for changes resulting from the acquisitions of Depop and Elo7, including purchase price allocations and valuation of the acquired intangible assets, developed technology, and goodwill, there are no new critical accounting estimates that were not included in our Annual Report or described above.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Management believes there are no material changes to our quantitative and qualitative disclosures about market risks during the nine months ended September 30, 2021, compared to those disclosed in the Annual Report.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of September 30, 2021. “Disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is (i) recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms and (ii) accumulated and communicated to the company’s management, including its principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure. Based on the evaluation of our disclosure controls and procedures, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of September 30, 2021 at the reasonable assurance level.

Our disclosure controls and procedures and internal control over financial reporting are designed to provide reasonable assurance of achieving the desired control objectives. Our management recognizes that any control system, no matter how well designed and operated, is based upon certain judgments and assumptions and cannot provide absolute assurance that its objectives will be met. Similarly, an evaluation of controls cannot provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, have been detected.

Changes in Internal Control 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) or 15d-15(d) of the Exchange Act during the third quarter of 2021 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

On July 2, 2021 we acquired Elo7 Serviços de Informática S.A. (“Elo7”) and on July 12, 2021 we acquired Depop Limited (“Depop”). We are currently integrating Elo7 and Depop into our operations and internal control processes and, pursuant to the SEC’s guidance that an assessment of a recently acquired business may be omitted from the scope of an assessment in the year of acquisition, the scope of our assessment of the effectiveness of our internal controls over financial reporting at December 31, 2021 will not include Elo7 and Depop.

Item 1. Legal Proceedings.

See “Note 9—Commitments and Contingencies—Legal Proceedings” in the Notes to Consolidated Financial Statements.

Item 1A. Risk Factors.

Investing in our securities involves a high degree of risk. You should consider carefully the risks and uncertainties described below, our Consolidated Financial Statements and related notes, and the other information in this Quarterly Report on Form 10-Q. If any of these risks actually occur, our business, financial condition, results of operations, and prospects could be adversely affected. As a result, the price of our securities could decline and you could lose part or all of your investment. In addition, factors other than those discussed below or in other of our reports filed with or furnished to the SEC also could adversely affect our business, financial condition or results of operations. We cannot assure you that the risk factors described below or elsewhere in our reports address all potential risks that we may face. These risk factors also serve to describe factors which may cause our results to differ materially from those described in forward-looking statements included herein or in other documents or statements that make reference to this Quarterly Report. See “Note Regarding Forward-Looking Statements.”

Operational Risks Related to Our Business

We have experienced rapid growth, and we may not have the infrastructure, human resources, or operational resources to sustain continued growth at our recent pace.

We experienced rapid growth in our business, in the number of buyers and sellers, and purchase frequency during 2020 and early 2021. Our revenue growth may not be sustainable. While our GMS, revenue, and Adjusted EBITDA grew in the third quarter of 2021 as compared to the third quarter of 2020, our rate of revenue growth decelerated in the second and third quarters of 2021 and may continue to decelerate as the ongoing COVID-19 pandemic runs its course and eventually abates, retail businesses reopen, and as the prior year comparison periods reflect our significant growth during the last nine months of 2020 and the first quarter of 2021. Even if our revenue continues to grow on a period over prior year period basis, we may not be able to maintain profitability in the future. In addition, our costs may increase as we continue to invest in the development of our marketplaces, including our services and technological enhancements, and increase our marketing efforts, expand our operations, and hire additional employees. Further, the growth of our business places significant demands on our management team and pressure to expand our operational, compliance, payments, and financial infrastructure. For example, we may need to continue to develop and improve our operational, financial, compliance, payments, and management controls and enhance our reporting systems and procedures to support our current and future growth.

Our rapid growth has made and may continue to make us a more attractive target to bad actors and fraudsters targeting our marketplaces and our communities, civil litigants, and those seeking to enforce questionable intellectual property rights. Our increased visibility may also lead to attempts to misrepresent or mischaracterize us or our marketplaces, such as on social media, or via individual or coordinated campaigns. In addition, the recent increased scrutiny and regulation of marketplace platforms, even though focused on other large platforms, has and may continue to create burdens on both Etsy and its communities of buyers and sellers. This may lead to increased risks that shift more quickly than our policies, enforcement mechanisms, and systems can react. We may not be successful in defending against these types of claims which, if successful, could damage our brands and our business. Even if we are successful in defending against these types of claims, we may be required to spend significant resources in those efforts which may distract our management and otherwise negatively impact our results of operations.

If we do not manage our growth effectively, the increases in our operating expenses could outpace any increases in our revenue and our business could be harmed. In addition, our revenue may decline and our revenue growth rate may continue to decelerate for a number of reasons, including the abatement of the COVID-19 pandemic and other factors described elsewhere in these Risk Factors. For further information about the rate of revenue and GMS growth, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Results of Operations—Revenue.” You should not rely on growth rates of prior periods as an indication of our future performance.

The COVID-19 pandemic is unprecedented and has impacted, and the pandemic and its eventual abatement may continue to impact, our GMS, key metrics, and results of operations in numerous ways that remain volatile and unpredictable.

We expect that COVID-19 and its economic and social impacts will continue to affect our business through the end of 2021 and possibly beyond. While COVID-19 vaccination efforts are ongoing, the timing, speed, and acceptance of vaccinations and timing of lifting of movement restrictions varies from location to location, is evolving, and to varying degrees across locations remains unknown. We continue to experience the uncertainty caused by the COVID-19 pandemic, including by the spread of variant

strains of COVID-19, and its potential impact on the global economy, e-commerce at large, and global macroeconomic conditions that impact consumer spending. In addition, the COVID-19 pandemic and related government and private sector responsive actions have affected the broader economies and financial markets, and have at points adversely affected, and could again adversely affect demand for products sold in our marketplaces. It is impossible to predict all the effects and the ultimate impact of the COVID-19 pandemic, as the situation continues to evolve. The COVID-19 pandemic has also disrupted the global supply chain and the preventative and protective measures currently in place, or which may be instituted or re-instituted in the future, such as quarantines, closures and movement restrictions, may interfere with the ability of our sellers to deliver products to our buyers. If delivery services are delayed or shut down or become more expensive, our GMS and revenue could be negatively impacted.

Our results of operations may be materially affected by adverse conditions in the capital markets and the economy generally, both in the United States and internationally. Uncertainty in the economy could adversely impact consumer purchases of discretionary items across all of our product categories, and demand for products available in our marketplaces may be reduced. Our results of operations have also been positively impacted by several trends related to the COVID-19 pandemic, including the shift from offline to online shopping, fast moving dynamics in the e-commerce space, retail business closures, stimulus checks, and emerging categories such as face masks. However, we have seen demand for certain items, like handmade masks, diminish significantly with the rollout of the vaccine, and as medical grade masks become widely available. It is also difficult to predict how our business might be impacted by changing consumer spending patterns when the pandemic abates. As pandemic-related restrictions on movement ease, competition may intensify as buyers return to traditional brick and mortar retail stores. Additionally, our sales may decline if pent-up demand for other discretionary spending replaces demand for online shopping. Other factors that could affect consumers’ willingness to make discretionary purchases include, among others: levels of employment, interest and core inflation rates, tax rates, housing costs, the availability of consumer credit, consumer confidence in future economic conditions, and stimulus checks. In the event of a prolonged economic downturn or acute recession, significant inflation, or increased supply chain shortages impacting our communities of sellers and the economy as a whole, consumer spending habits could be adversely affected, and we could experience lower than expected GMS, revenue, net income, and Adjusted EBITDA.

As a result of the ongoing COVID-19 pandemic, our employees continue to work remotely, and it is possible that this could have a negative impact on the execution of our business plans and operations. If a natural disaster, power outage, connectivity issue, or other event occurred that impacted our employees’ ability to work remotely, it may be difficult or, in certain cases, impossible, for us to continue our business for a substantial period of time. The increase in remote working for employees, vendors, or contractors may also result in increased consumer privacy, IT security, and fraud concerns. Further, as certain businesses return to on-site operations, we may experience disruptions if our employees or third-party service providers’ employees become ill despite the availability of vaccines, and are unable to perform their duties. This may impact our operations, internet, or mobile networks, or the operations of one or more of our third-party service providers.

The uncertainty around the duration of business disruptions, the timing and acceptance of vaccine rollouts, herd immunity, the lifting of remaining travel restrictions in the United States and other areas of the world and consumers’ responses to these developments may adversely impact the national and/or global economy and negatively impact consumer discretionary spending, even in the e-commerce space, which experienced growth during the pandemic. The full extent of COVID-19’s impact on our operations, key metrics, and financial performance depends on future developments that are uncertain and unpredictable, including the timing and acceptance of vaccine rollouts and herd immunity in various locations, the timing of further relaxation or elimination of movement and travel restrictions, the occurrence of virus mutations and variants, the pandemic’s impact on capital and financial markets, and any new information that may emerge concerning the virus, vaccines, and containment, all of which may vary across regions. Any of these factors could have a material adverse impact on our business, financial condition, operating results, and ability to execute and capitalize on our strategies.

Our quarterly operating results may fluctuate, which could cause our stock price to decline.

Our quarterly operating results, as well as our key metrics, may fluctuate for a variety of reasons, many of which are beyond our control, including:

•fluctuations in GMS or revenue, including as a result of adverse market conditions due to the COVID-19 pandemic and the re-opening of traditional brick and mortar retail and other options for discretionary spending as and when restrictions on movement are loosened further or entirely removed, the impact or the waning of the impact of any government stimulus package, the seasonality of market transactions, and our sellers’ use of services;

•our ability to convert visits into sales for our sellers;

•the amount and timing of our operating expenses;

•our success in attracting and retaining sellers and buyers;

•our success in executing on our strategy and the impact of any changes in our strategy;

55

•the timing and success of product launches, including new services and features we may introduce;

•the success of our marketing efforts;

•the success of our acquired businesses, such as Depop and Elo7, each of which we acquired in July 2021, and Reverb, which we acquired in 2019;

•our ability to integrate Depop and Elo7 and implement our “House of Brands” strategy;

•adverse economic and market conditions, including those related to the current COVID-19 pandemic, currency fluctuations, rapidly rising inflation, and adverse global events;

•disruptions or defects in our marketplaces, such as privacy or data security breaches, errors in our software, or other incidents that impact the availability, reliability, or performance of our platforms;

•the impact of competitive developments and our response to those developments;

•our ability to manage our business and future growth; and

•our ability to recruit and retain employees.

Fluctuations in our quarterly operating results, key metrics, and the price of our common stock may be particularly pronounced in the current economic environment due to the uncertainty caused by, and the unprecedented nature of, the current COVID-19 pandemic, consumer spending patterns, and the impacts of the reopening of the offline economy and lessening or elimination of restrictions on movement. Fluctuations in our quarterly operating results and key metrics may cause those results to fall below our financial guidance or other projections, or the expectations of analysts or investors, which could cause the price of our common stock to decline. Fluctuations in our results could also cause a number of other problems. For example, analysts or investors might change their models for valuing our common stock, we could experience short-term liquidity issues, our ability to retain or attract key personnel may diminish, and other unanticipated issues may arise.

We believe that our quarterly operating results and key metrics may vary in the future and that period-to-period comparisons of our operating results may not be meaningful. For example, our overall historical growth rate and the impacts of the COVID-19 pandemic may have overshadowed the effect of seasonal variations on our historical operating results. These seasonal effects may become more pronounced over time, which could also cause our operating results and key metrics to fluctuate. You should not rely on quarter-to-quarter comparisons of our results of operations as an indication of future performance.

We may fail to meet our publicly announced guidance or other expectations about our business and future operating results, which would cause our stock price to decline.

From time to time, we release earnings guidance in our quarterly and annual earnings conference calls, quarterly and annual earnings releases, or otherwise, regarding our future performance that represents our management’s estimates as of the date of release. For example, we historically have provided annual guidance, but we withdrew our 2020 annual guidance on April 2, 2020 given the economic uncertainty caused by the COVID-19 pandemic and have been providing only quarterly guidance since.

On November 3, 2021, we provided guidance for the fourth quarter of 2021. This guidance includes forward-looking statements based on projections prepared by our management. Projections are based upon a number of assumptions and estimates that, while presented with numerical specificity, are inherently subject to significant business, economic, and competitive uncertainties and contingencies relating to our business, many of which are beyond our control and are based upon specific assumptions with respect to future business decisions, some of which will change. Some of those key assumptions include the impact of the COVID-19 pandemic and its duration, particularly as vaccines become widely rolled-out and restrictions on movement are lifted, future consumer spending patterns, and the associated economic uncertainty on our business. These assumptions are inherently difficult to predict, particularly in the long term. In addition, we completed the acquisition of Elo7 on July 2, 2021 and Depop on July 12, 2021. While all guidance is necessarily speculative in nature, guidance relating to the anticipated results of operations of a recently acquired business is inherently more speculative in nature than other guidance as management will, necessarily, be less familiar with the business, procedures, and operations of the recently acquired business. It can be expected that some or all of the assumptions regarding Depop and Elo7 underlying any guidance furnished by us will not materialize or will vary significantly from actual results. We generally state possible outcomes as high and low ranges which are intended to provide a sensitivity analysis as variables are changed but are not intended to imply that actual results could not fall outside of the suggested ranges. Furthermore, analysts and investors may develop and publish their own projections of our business, which may form a consensus about our future performance. Our actual business results may vary significantly from such guidance or that consensus due to a number of factors, many of which are outside of our control, including due to the global economic uncertainty and financial market conditions caused by the ongoing COVID-19 pandemic, and the impacts of reduced movement or the removal of restrictions on movement, which could adversely affect our business and future operating results. There are no comparable recent events that provide insights on the probable effects of the ongoing COVID-19 pandemic or its eventual abatement, and, as a result, the ultimate impact of the COVID-19 pandemic is highly uncertain and subject to

56

Table of Contents

change. We are relying on the reports and models of economic and medical experts in making assumptions relating to the duration of this crisis, resumption of freedom of movement in various regions and predictions as to timing and pace of any future economic recovery. If these models are incorrect or incomplete, or if we fail to accurately predict the full impact that the ongoing COVID-19 pandemic or its eventual abatement will have on all aspects of our business or the duration of those impacts, the guidance and other forward-looking statements we provide may also be incorrect or incomplete. Furthermore, if we make downward revisions of our previously announced guidance, or if our publicly announced guidance of future operating results fails to meet expectations of securities analysts, investors, or other interested parties, the price of our common stock could decline.

Given the uncertainty surrounding the impacts and duration of COVID-19, the efficacy of a vaccine, and the timing and impact of the easing of restrictions on movement, we may continue to provide more limited quarterly guidance, as we did in 2020 and 2021. Guidance is necessarily speculative in nature, and it can be expected that some or all of the assumptions underlying the guidance furnished by us will not materialize or will vary significantly from actual results. Accordingly, our guidance is only an estimate of what management believes is realizable as of the date of release. Actual results may vary from our guidance and the variations may be material. In light of the foregoing, investors are urged not to rely upon our guidance in making an investment decision regarding our common stock.

Any failure to successfully implement our operating strategy or the occurrence of any of the events or circumstances set forth in this Risk Factors section in this report could result in the actual operating results being different from our guidance, and the differences may be adverse and material.

If we experience a technology disruption or failure that results in a loss of information, if personal data or sensitive information about members of our communities or employees is misused or disclosed, or if we or our third-party providers are unable to protect against software and hardware vulnerabilities, service interruptions, cyber incidents, ransomware, security incidents, or security breaches, then members of our communities may curtail use of our platforms, we may be exposed to liability or incur additional expenses, and our reputation could suffer.

Like all online services, we are vulnerable to power outages, telecommunications failures, and catastrophic events, as well as computer viruses, break-ins, phishing attacks, denial-of-service attacks, ransomware, and other cyber incidents. Any of these occurrences could lead to interruptions or shutdowns of one or more of our platforms, loss of data, or unauthorized disclosure of personal or financial information of our members or employees. As we grow our business, expand internationally, and gain greater public visibility, we may face a higher risk of being targeted by cyber attacks. Although we have integrated a variety of recovery systems, security protocols, network protection mechanisms and other security measures into our systems, networks and physical facilities, which are designed to protect against, detect and minimize security breaches, including security testing, encryption of sensitive information, and authentication technology, we cannot assure you that such measures will be adequate to prevent or detect service interruption, system failure, data loss or theft, or other material adverse consequences, particularly given the increasingly sophisticated tools and methods used by hackers, organized cyber criminals, and cyber terrorists. While we are investing in the recovery systems, security and access controls, and assessments of our vendors’ security for us and our recently acquired subsidiaries, these systems and controls are not yet fully in place and, even when in place, have not always been in the past, and in the future may not be, sufficient to prevent or detect a cyber attack, system failure, or security breach.

In addition, we have experienced in the past, and may experience in the future, technology disruptions, cyber incidents, and security breaches, including intentional, inadvertent, or social engineering breaches occurring through our employees or employees of our third-party service providers. As in the past, if our employees or employees of our third-party service providers fail to comply with our internal security policies and practices, member or employee data may be improperly accessed, used, or disclosed.

Our security and access controls for our systems may not be adequate, which may heighten the risk of a cyber attack or security breach. Among other things, our applications, systems, networks, software and physical facilities could have material vulnerabilities, be breached or the personal or confidential information that we store could be otherwise compromised due to employee error or malfeasance, if, for example, third parties attempt to fraudulently induce our employees or our members to disclose information or user names and/or passwords, or otherwise compromise the security of our networks, systems and/or physical facilities. As in the past, employees or service providers may inadvertently misconfigure resources or misdirect certain communications in manners that may lead to security incidents on which we must then expend effort and expenses to correct.

As we have moved to a fully remote work environment due to the COVID-19 pandemic, and as the industry generally moves to online remote infrastructure for core work, we and our partners may be more vulnerable to cyber attacks. Cyber attacks could also result in the theft of our intellectual property or user data.

A successful cyber attack could occur and persist for an extended period of time before being detected. Because the techniques used by hackers change frequently, we may be unable to anticipate these techniques or implement adequate preventive measures. In addition, because any investigation of a cybersecurity incident would be inherently unpredictable, the extent of a particular cybersecurity incident and the path of investigating the incident may not be immediately clear. It may take a significant amount of time before an investigation can be completed and full and reliable information about the incident is known. While an investigation is ongoing, we may not necessarily know the extent of the harm or how best to remediate it, certain errors or

57

Table of Contents

actions could be repeated or compounded before they are discovered and remediated, and communication to the public, regulators, members of our communities, and other stakeholders may be inaccurate, any or all of which could further increase the costs and consequences of a cybersecurity incident. Applicable rules regarding how to respond, notice to users and reporting to regulators vary by jurisdiction, and may subject Etsy to additional liability and reputational harm.

Our production systems rely on internal technology, along with cloud services and software provided by our third-party service providers. In the event of a cyber-incident, even partial unavailability of our production systems could impair our ability to serve our customers, manage transactions, or operate our marketplaces. We have implemented disaster recovery mechanisms, including systems to back up key data and production systems, but these systems may be inadequate or incomplete. For example, these disaster recovery systems may be susceptible to cyber-incidents if not sufficiently separated from primary systems, not comprehensive, or not at a scale sufficient to replace our primary systems. Insufficient production and disaster recovery systems could, in the event of a cyber-incident, harm our growth prospects, our business, and our reputation for maintaining trusted marketplaces.

The costs and effort to respond to a security breach and/or to mitigate any security vulnerabilities that may be identified could be significant, our efforts to address these problems may not be successful, and these problems could result in unexpected interruptions, delays, cessation of service, negative publicity, and other harm to our business and our competitive position. We could be required to fundamentally change our business activities and practices in response to a security breach or related regulatory actions or litigation, which could have an adverse effect on our business.

Cyber attacks aimed at disrupting our and our third-party service providers’ services have occurred regularly in the past, and we expect they will continue to occur in the future. If we or our third-party service providers experience security breaches that result in marketplace performance or availability problems or the loss, compromise, or unauthorized disclosure of personal data or other sensitive information, or if we fail to respond appropriately to any security breaches that we may experience, people may become unwilling to provide us the information necessary to set up an account with us. Existing sellers and buyers may stop listing new items for sale, decrease their purchases, or close their accounts altogether. We could also face damage to our reputation, potential liability, regulatory investigations in multiple jurisdictions, and costly remediation efforts and litigation, which may not be adequately covered by, and which may impact our future access to, insurance. Any of these results could harm our growth prospects, our business, and our reputation for maintaining trusted marketplaces.

We are also reliant on the security practices of our third party service providers, which may be outside of our direct control. Additionally, some of our third party service providers, such as identity verification and payment processing providers, regularly have access to payment card information and other confidential and sensitive member data. We may have contractual and regulatory obligations to supervise the security and privacy practices of our third-party service providers. Despite our best efforts, if these third parties fail to adhere to adequate security practices, or, as has occurred from time to time in the past, experience a cyber incident or attack such as a breach of their networks, our members’ data may be rendered unavailable, improperly accessed, used, or disclosed. More generally, our third-party service providers may not have adequate security and privacy controls, may not properly exercise their compliance, regulatory or notification requirements, including as to personal data, or may not have the resources to properly respond to an incident. Many of our service providers have moved to a remote work environment and may, as a result, be more vulnerable to cyber attacks.

Our software is highly complex and may contain undetected errors.

The software underlying our platforms is highly interconnected and complex and may contain undetected errors or vulnerabilities, some of which may only be discovered after the code has been released. We rely heavily on a software engineering practice known as “continuous deployment,” meaning that we typically release software code many times per day. This practice may result in the more frequent introduction of errors or vulnerabilities into the software underlying our platforms, which can impact the user experience and functionality of our marketplaces. Additionally, due to the interconnected nature of the software underlying our platforms, updates to parts of our code, third party code, and APIs, on which we rely and that maintain the functionality of our marketplaces and business, could have an unintended impact on other sections of our code, which may result in errors or vulnerabilities to our platforms that negatively impact the user experience and functionality of our marketplaces. In some cases, such as our mobile apps, errors may only be correctable through updates distributed through slower, third party mechanisms, such as app stores, and may need to comply with third party policies and procedures to be made available, which may add additional delays due to app review and user delay in updating their mobile apps. In addition, our systems are increasingly reliant on machine learning systems, which are complex and may have errors or inadequacies that are not easily detectable. These systems may inadvertently reduce the efficiency of our systems, or may cause unintentional or unexpected outputs that are incorrect, do not match our business goals, do not comply with our policies, or otherwise are inconsistent with our brands, guiding principles, and mission. Any errors or vulnerabilities discovered in our code after release could also result in damage to our reputation, loss of members of our communities, loss of revenue, or liability for damages, any of which could adversely affect our growth prospects and our business.

We rely on Google Cloud for a substantial portion of the computing, storage, data processing, networking, and other services for Etsy.com.

Google Cloud Platform provides a distributed computing infrastructure as a service platform for business operations, and we have migrated Etsy.com’s primary production environment and data centers to Google Cloud, increasing our reliance on cloud infrastructure. Any transition of the cloud services currently provided by Google Cloud to another cloud provider would be difficult to implement and will cause us to incur significant time and expense. Our products and services are in significant part reliant on continued access to, and the continued stability, reliability, and flexibility of Google Cloud. Any significant disruption of, or interference with, our use of Google Cloud would negatively impact our operations, and our business would be seriously harmed. In addition, if hosting costs increase over time and if we require more computing or storage capacity, our costs could increase disproportionately. If we are unable to grow our revenues faster than the cost of utilizing the services of Google or similar providers, our business and financial condition could be adversely affected. Reverb, Depop, and Elo7 rely on Amazon Web Services for some business operations, and those marketplaces are thus subject to analogous risks.

The trustworthiness of our marketplaces and the connections within our communities are important to our success. Our business, financial performance, and growth depend on our ability to attract and retain active and engaged communities of buyers and sellers. If we are unable to retain our existing buyers and sellers and activate new ones, our financial performance could decline.

We are focused on ensuring that our marketplaces embody our mission and values, and that we deliver trust and reliability throughout the buyer and seller experiences. Our reputation and brands depend, in part, upon our ability to maintain trustworthy marketplaces, and also upon our sellers, the quality of their offerings, their adherence to our policies, and their ability to deliver a trusted purchasing experience. We view the trustworthiness and reliability of our marketplaces, as well as the connections we foster in our buyer/seller communities, to be cornerstones of our business and key to our success. Many things could undermine these cornerstones, such as:

•complaints or negative publicity about us, our platforms, or our policies and guidelines, even if factually incorrect or based on isolated incidents;

•an inability to gain the trust of prospective buyers;

•disruptions or defects in our marketplaces, privacy or data security incidents, website outages, payment disruptions or other incidents that impact the reliability of our platforms;

•lack of awareness of our policies or confusion about how they are applied;

•changes to our policies that members of our communities perceive as inconsistent with their best interests or our mission, or that are not clearly articulated;

•inadequacies in our terms of use;

•frequent product launches, updates, and experiments that could deteriorate member trust;

•a failure to enforce our policies effectively, consistently, and transparently, including, for example, by allowing the widespread listing of prohibited items in our marketplaces;

•inadequate or unsatisfactory customer service experiences;

•a failure on the part of our sellers to fulfill their orders in accordance with our policies, their own shop-specific policies, or buyer expectations;

•a failure to respond to feedback from our communities; or

•a failure to operate our business in a way that is consistent with our guiding principles and mission.

Creating trusted brands is one of the key elements of our strategy. In particular, we are focused on enhancing the customer experience for both sellers and buyers. We continue to evolve our offerings and invest to improve our customer experience on our marketplaces. If our efforts are unsuccessful, or if our customer service platforms or our trust and safety program fail to meet our requirements, legal requirements, or our customers’ requirements, we may need to quickly invest significant additional resources. If we are unable to do so, our ability to maintain trustworthy marketplaces, attract buyers and sellers, and maintain our trusted brands, could be harmed.

Our business, financial performance and growth depends on our ability to attract and retain active and engaged communities of buyers and sellers.

Our financial performance has been and will continue to be significantly determined by our success in attracting and retaining active buyers and active sellers. For example, our revenue is driven by the number of active buyers and buyer engagement, as well as the number of active sellers and seller engagement. If we are not successful in encouraging buyers to return to us and purchase items in our marketplaces more frequently and sellers to list items for sale and use our services, our financial performance may be negatively impacted.

Our GMS and revenue is concentrated in our most active buyers and sellers. The pandemic fueled an unprecedented increase in the growth of new buyers and reactivated lapsed buyers, although in recent quarters we have seen the growth rate decline on a year over year basis. We have also seen a higher than recent historic growth rate of new sellers. If we lose a significant number of those buyers, or sellers, due to the abatement of pandemic restrictions or otherwise, our financial performance and growth could be harmed. Even if we are able to attract new buyers and sellers to replace the ones that we lose, we may not be able to do so at 2020 levels, they may not maintain the same level of activity, and the GMS and revenue generated from new buyers and sellers may not be as high as the GMS and revenue generated from the ones who leave our marketplaces. If we are unable to retain existing buyers and sellers and attract new buyers and sellers who contribute to active communities, our business, financial performance, and growth could be harmed.

Additionally, the demand for the goods listed in our marketplaces is dependent on consumer preferences which can change quickly and may differ across generations and cultures, or due to other macro events. If demand for the goods that our sellers offer declines, we may not be able to attract and retain our buyers and our business could be harmed. A shift in trends away from socially-conscious consumerism or unique or vintage goods, could also make it more difficult to attract new buyers and sellers. Our growth would also be harmed if the shift from brick and mortar retail to e-commerce does not continue, or reverses when the COVID-19 pandemic abates and as restrictions on movement are further lifted. We believe that many new buyers and sellers find us by word of mouth and other non-paid referrals from existing buyers and sellers. If existing buyers do not find our platforms appealing, whether because of a negative experience, lack of competitive shipping costs, delayed shipping times, inadequate customer service, lack of buyer-friendly features, declining interest in the nature of the goods offered by our sellers, or other factors, they may make fewer purchases and they may stop referring others to us. Likewise, if existing sellers are dissatisfied with their experience on our platforms, or feel they have more attractive alternatives, they may stop listing items in our marketplaces and using our services and may stop referring others to us. Under any of these circumstances, we may have difficulty attracting new buyers and sellers without incurring additional expense.

We rely on our sellers to provide a fulfilling experience to our buyers.

A small portion of buyers complain to us about their experience on our platforms. As a pure marketplace, our sellers manage their shops, most policies, products and product descriptions, shipping and returns. As a result, we may not have the ability to control important aspects of buyers’ experiences on our platforms. For example, buyers may report that they have not received the items that they purchased, that the items received were not as represented by a seller, or that a seller has not been responsive to their questions. Similarly, we occasionally identify sellers who are unable to fulfill orders in a time frame or manner consistent with buyer expectations. Trending sellers may experience an influx of orders that may be beyond their ability to fulfill in a timely manner. For example, a subset of sellers who offered cloth masks during 2020 may have experienced periods of high activity beyond their ability to fulfill as a small business. While we have procedures designed to mitigate spikes in orders, we cannot guarantee those procedures will be effective.

Negative publicity and sentiment generated as a result of these types of complaints, or any associated enforcement action taken against sellers, could reduce our ability to attract and retain our sellers and buyers or damage our reputation. We take action against sellers who we are aware may have violated our policies. However, our actions may be insufficient, may not be timely, and may not be effective in creating a good purchase experience for our buyers or avoiding negative publicity.

As our marketplaces grow, our controls over fraud and policy violations are important to maintaining user trust, but they may not be adequate and may not be sufficient to keep up with quickly-shifting techniques used by those attempting to undertake fraudulent activity on our platforms. While we regularly update our processes for handling complaints and detecting policy violations, these processes are by their nature imperfect in a dynamic, quickly growing marketplace, and include risk to us, our sellers, and our buyers from both under-enforcement and over-enforcement.

A perception that our levels of responsiveness and support for our sellers and buyers are inadequate could have similar results. In some situations, we may choose to reimburse our buyers for their purchases to help avoid harm to our reputation. While we take steps such as requiring reserves, including to cover such reimbursements, from some sellers based on indicia they may not be able to fulfill orders, we may not be able to recover the funds we expend for those reimbursements. When we do recover funds used to reimburse buyers from sellers, it may increase general seller dissatisfaction and reduce their desire to continue selling using our platforms. Although we are focused on enhancing customer service, our efforts may be unsuccessful and our sellers and buyers may be disappointed in their experience and not return.

Anything that prevents the timely processing of orders or delivery of goods to our buyers could harm our sellers. Service interruptions and delivery delays may be caused by events that are beyond the control of our sellers, such as interruptions in order or payment processing, interruptions in sellers’ supply chain, transportation disruptions, customs delays, natural disasters, inclement weather, terrorism, public health crises, or political unrest. For example, a number of countries continue to experience delays in shipping due to the COVID-19 pandemic, and supply chain disruptions and shipping delays may become more widespread. If buyers have a negative purchase experience, whether due to delay or other reasons, our reputation could be damaged.

Our business depends on third party services and technology which we utilize to maintain and scale the technology underlying our platforms and our business operations.

Our business operations are dependent upon a number of third-party service providers, such as cloud service providers, marketing platforms and providers, payments and shipping providers, and contingent labor teams, and network and mobile infrastructure providers. Any disruption in their services, any failure on their part to deliver their services in accordance with our scale and expectations, or any failure on our part to maintain appropriate oversight on these third-party providers during the course of our engagement with them, could significantly harm our business.

We are unable to exercise significant oversight over some of these providers, which increases our vulnerability to their financial conditions and to problems with the services they provide, such as technical failures, deprecation of key services, privacy or security concerns. Our efforts to update our infrastructure or supply chain may not be successful as we may not sufficiently distribute our risk across providers or geographies or our efforts to do so may take longer than anticipated. If we experience failures in our technology infrastructure or supply chain or do not expand our technology infrastructure or supply chain successfully, then our ability to run our marketplaces could be significantly impacted, which could harm our business.

Our business depends on continued and unimpeded access to third party services, platforms and infrastructure that we rely upon to maintain and scale our platforms.

Our sellers and buyers rely on access to the internet or mobile networks to access our marketplaces. Internet service providers may choose to disrupt or degrade access to our platforms or increase the cost of such access. Mobile network operators or operating system providers could block or place onerous restrictions on the ability to download and use our mobile apps.

Internet service providers or mobile network operators could also attempt to charge us for providing access to our platforms. In addition, we could face discriminatory or anticompetitive practices that could impede both our and our sellers’ growth prospects, increase our costs, and harm our business.

Outside of the United States, governments of one or more countries have in the past and may continue to seek to censor content available on our platforms, attempt to apply their local requirements extra-territorially, or may even attempt to block access to our platforms. If we are restricted from operating in one or more countries, our ability to attract and retain sellers and buyers may be adversely affected and we may not be able to grow our business as we anticipate.

In addition, our sellers rely on continued and unimpeded access to postal services and shipping carriers to deliver their goods reliably and timely to buyers. As a result of the COVID-19 pandemic and other factors, our sellers have experienced increased delays in delivery of their goods. If these shipping delays continue or worsen, or if shipping rates increase significantly, our sellers may have increased costs, and/or our buyers may have a poor purchasing experience and may lose trust in our marketplaces, which could negatively impact our business, financial performance, and growth.

Our payments systems have both operational and compliance risks, including in-house execution risk, dependency on third-party providers, and a complex landscape of evolving laws, regulations, rules, and standards.

Buyers on our Etsy and Reverb marketplaces primarily pay for purchases using our payments services (i.e., Etsy Payments and Reverb Payments (only available in the United States)), or PayPal and, in certain jurisdictions, may pay in installments with Klarna. Our marketplaces also utilize various third party payment processors: International buyers pay for purchases on Reverb using Ayden; buyers on Depop use Stripe or PayPal; and buyers on Elo7 use MoIP. In the United States and other countries where our payments services are available, our sellers accept various forms of payments such as credit cards, debit cards, gift cards, PayPal, Google Wallet, and Apple Pay. We plan to invest ongoing internal resources into our payments tools and infrastructure to maintain existing availability, expand into additional markets, and offer new payment methods and tools to our buyers and sellers. If we fail to invest adequate resources into our payments platforms, or if our investment efforts are unsuccessful or unreliable, our payments services may not function properly, keep pace with competitive offerings, or comply with applicable laws and regulatory requirements, any of which could negatively impact their usage and our marketplaces, as well as our trusted brands, which, in turn, could adversely affect our GMS and results of operations.

We rely upon third-party service providers to perform key components of our payments platforms, including payments processing and payments disbursing, compliance, currency exchange, identity verification, sanctions screening, and fraud analysis. If these service providers do not perform adequately, or if our relationships with these service providers were to change

61

Table of Contents

or terminate, it could negatively affect our sellers’ ability to receive orders or payments, our buyers’ ability to complete purchases, and our ability to operate our payments program, including maintaining certain compliance measures, including fraud prevention and detection tools. This could decrease revenue, increase costs, lead to potential legal liability, and negatively impact our brands and business. If we (or a third-party payment processor) suffer a security breach affecting payment card information, we could be subjected to fines, penalties and assessments arising out of the major card brands’ rules and regulations, contractual indemnification obligations or other obligations contained in merchant agreements and similar contracts, and we may lose our ability to accept payment cards as payment for our services and our sellers’ goods and services.

In addition, we and our third-party service providers may experience service outages from time to time that negatively impact payments on our platforms. We have in the past experienced, and may in the future experience, such payments-related service outages and, if we are unable to promptly remedy or provide an alternative payment solution, our business could be harmed. In addition, if our third-party providers increase the fees they charge us, our operating expenses, or those of our sellers, could increase, and it could negatively impact our sellers’ businesses or our business.

Further, our ability to expand our payments services into additional countries is dependent upon the third-party providers we use to support these services. As we expand the availability of our payments services to additional markets or offer new payment methods to our sellers and buyers in the future, we, along with our sellers, may become subject to additional and evolving regulations, compliance requirements, and may be exposed to heightened fraud risk, which could lead to an increase in our operating expenses.

Various laws and regulations govern payments, and these laws are complex, evolving, and subject to change and vary across different jurisdictions in the United States and globally. Moreover, even in regions where such laws have been harmonized, regulatory interpretations of such laws may differ. As a result, we are required to spend significant time and effort determining whether various licensing and registration laws relating to payments apply to us as our business strategy and operations evolve. Any failure or claim of our failure to comply, or any failure by our third-party service providers to comply, could cost us substantial resources, result in liabilities, cause us significant reputational damage, or force us to stop offering our payments services in certain markets. Additionally, changes in payment regulation may occur that could render our payments systems non-compliant and/or less profitable.

Further, through our agreements with our third-party payments service providers, we are and could be subject to evolving rules and certification requirements (including the Payment Card Industry Data Security Standard), or other contractual requirements that may materially negatively impact our payments business. Failure to comply with these rules and requirements could impact our ability to meet our contractual obligations with our third-party payment processors and could result in potential fines or negatively impact our relationship with our third-party payments processors.

We are also subject to rules governing electronic funds transfers. Any change in these rules and requirements, including as a result of a change in our designation by major payment card providers, could make it difficult or impossible for us to comply and could require a change in our business operations. In addition, similar to a potential increase in costs from third-party providers described above, any increased costs associated with compliance with payment card association rules or payment card provider rules could lead to increased fees for us or our sellers, which may negatively impact payments on our platforms, usage of our payments services, and our marketplaces.

Our business could be adversely affected by economic downturns, natural disasters, public health crises such as the COVID-19 pandemic, political crises, geopolitical changes or other similar events.

Macroeconomic conditions may adversely affect our business. If general economic conditions deteriorate in the United States or other markets where we operate, consumer discretionary spending may decline and demand for the goods and services available on our platforms may be reduced. This would cause our Marketplace and Services revenue to decline and adversely impact our business. For example, the ongoing COVID-19 pandemic has caused significant uncertainty and volatility in the global economy, and we have seen significant and rapid shifts in consumer purchasing behavior as this pandemic has evolved, particularly as it relates to items sought on Etsy. It is difficult to predict how our business might be impacted by changing consumer spending patterns.

If recent trends supporting self-employment, and the desire for supplemental income were to reverse, the number of sellers offering their goods in our marketplaces and the number of goods listed in our marketplaces could decline. In addition, currency exchange rates may directly and indirectly impact our business. If the U.S. dollar strengthens or weakens against foreign currencies, particularly if there is short term volatility, our foreign currency denominated GMS and revenue, when translated into U.S. dollars, could fluctuate significantly. Currency exchange rates may also dampen demand for cross-border purchases, which could impact GMS and revenue. For the nine months ended September 30, 2021, approximately 74% of our GMS was denominated in U.S. dollars.

Any events causing significant disruption or distraction to the public or to our workforce, such as natural disasters and other adverse weather and climate conditions, public health crises, supply chain disruptions, political instability or crises, terrorist attacks, war, social unrest, or other unexpected events, could disrupt our operations, internet, or mobile networks, or the operations of one or more of our third-party service providers. These events, if they occur, may impact buyer demand for

62

discretionary goods, impact sellers’ ability to run their businesses on our marketplaces and ship their goods, and impact our ability to execute on our strategy, any of which could negatively impact our business and financial performance.

Further expansion outside of the United States will subject us to risks associated with operations abroad.

Doing business outside of the United States subjects us to increased risks and burdens such as:

•complying with different (and sometimes conflicting) laws and regulatory standards (particularly including those related to the use and disclosure of personal information, online payments and money transmission, intellectual property, product liability, consumer protection, online platform liability, e-commerce marketplace regulation, labor and employment laws, business practices, including those related to the environment, and taxation of income, goods, and services) sometimes with attempts to apply these laws and regulatory standards extraterritorially;

•defending our marketplaces against international litigation, including in jurisdictions that may not offer judicial norms or protections similar to those found in the United States;

•conforming to local business or cultural norms;

•barriers to international trade, such as tariffs, customs, or other taxes, or, when applicable, cross-border limits placed on U.S. technology companies;

•uncertainties on the continuing impact of pandemic-related quarantines, closures, delayed or shut down delivery services, supply chain delays, and movement restrictions on operations, and geopolitical events such as natural disasters, pandemics, terrorism, and acts of war;

•varying levels of internet, e-commerce, and mobile technology adoption and infrastructure;

•potentially heightened risk of fraudulent or other illegal transactions;

•limitations on the repatriation of funds;

•exposure to liabilities under anti-corruption, anti-money laundering and export control laws, including the U.S. Foreign Corrupt Practices Act of 1977, as amended, the U.K. Bribery Act of 2010, trade controls and sanctions administered by the U.S. Office of Foreign Assets Control of the U.S. Treasury Department, and similar laws and regulations in other jurisdictions;

•our ability to enforce contracts, our terms of use and policies, and intellectual property rights in jurisdictions outside the United States;

•fluctuations of foreign exchange rates; and

•uncertainties and instability in U.K. and E.U. markets caused by ongoing negotiations of cross-border service agreements triggered by Brexit.

Our sellers face similar risks in conducting their businesses across borders. Even if we are successful in managing the risks of conducting our business across borders, if our sellers are not, our business could be adversely affected.

Our ability to recruit and retain a diverse group of employees is important to our success.

Our ability to attract, retain, and motivate a diverse group of employees, including our management team, is important to our success. We strive to attract, retain, and motivate our employees, from our office administrators to our engineers, to our management team, who share our dedication to our communities and our mission to “Keep Commerce Human.” We cannot guarantee we will continue to attract and retain the number or caliber of employees we need to maintain our competitive position, particularly in the uncertainty of the current macroeconomic environment. We may not meet our impact goal of building diverse and inclusive workforces that are broadly representative of their communities.

Some of the challenges we face in attracting and retaining employees include:

•skepticism regarding our ability to accelerate GMS growth in the future;

•continuing ability to offer competitive compensation and benefits;

•evolving expectations regarding the ability to work remotely;

•enhancing engagement levels among existing employees and supporting their work-life balance;

63

Table of Contents

•attracting high quality talent in a timely fashion;

•retaining qualified employees who support our mission and guiding principles, including employees of recently acquired companies such as Depop and Elo7, and continuing to do so in a remote or hybrid work environment;

•continuing to find promotion opportunities to retain key employees for leadership positions;

•hiring employees in multiple locations globally, and building a diverse equitable and inclusive workforce; and

•responding to competitive pressures and changing business conditions in ways that do not divert us from our guiding principles.

Filling key strategic roles, including engineering and product management, particularly in New York City, San Francisco, Dublin, and Chicago, is challenging and may be challenging in London, Sao Paulo, and Mexico City as well, as competition for engineering talent continues to increase rapidly. Qualified individuals are limited and in high demand, and we may incur significant costs to attract, develop, retain and motivate them. Even if we were to offer higher compensation and other benefits, people with suitable technical skills may choose not to join us or to continue to work for us. In addition, job candidates and existing employees often consider the value of the stock awards they receive in connection with their employment. If the perceived value of our stock awards declines, particularly in this volatile macroeconomic environment, it may adversely affect our ability to recruit and retain highly skilled employees.

Our employees are currently almost fully remote. As stay-at-home orders and movement restrictions are lifted and we contemplate reopening our offices, we are planning to migrate towards a hybrid work model where some of our employees may remain fully remote and others may return to our offices two or more days a week. If our needs are not aligned with our employees’ preferences, it may adversely affect our ability to recruit and retain employees. If we do move to a more remote work model, it may negatively impact our company culture.

In general, our employees, including our management team, work for us on an at-will basis. The unexpected loss of or failure to retain one or more of our key employees, such as our Chief Executive Officer, Chief Financial Officer, or Chief Technology Officer, or unsuccessful succession planning, could adversely affect our business. Further, if members of our management and other key personnel in critical functions across our organization are unable to perform their duties, we may not be able to execute on our business strategy and/or our operations may be negatively impacted. Other companies, including our competitors, may be successful in recruiting and hiring our employees, and it may be difficult for us to find suitable replacements on a timely basis or on competitive terms.

If we experience increased voluntary attrition in the future, and/or if we are unable to attract and retain qualified employees in a timely fashion or on reasonable terms, particularly in critical areas of operations such as engineering, we may not achieve our strategic goals and our business and operations could be harmed.

We may be unable to adequately protect our intellectual property.

Our intellectual property is an essential asset of our business. To establish and protect our intellectual property rights, we rely on a combination of copyright, trademark, and patent laws, as well as confidentiality procedures and contractual provisions. We also rely on trade secret protection for parts of our technology and intellectual property. The efforts we have taken to protect our intellectual property may not be sufficient or effective. We generally do not elect to register our copyrights, relying instead on the laws protecting unregistered intellectual property, which may not be sufficient. We rely on both registered and unregistered trademarks, which may not always be comprehensive in scope. In addition, our copyrights and trademarks, whether or not registered, and patents may be held invalid or unenforceable if challenged, and may be of limited territorial reach. While we have obtained or applied for patent protection with respect to some of our intellectual property, patent filings may not be adequate alone to protect our intellectual property, and may not be sufficiently broad to protect our proprietary technologies. From time to time we acquire intellectual property from third parties, but these acquired assets, like our internally developed intellectual property, may be held invalid, be unenforceable, or may otherwise not be effective in protecting our platforms.

In addition, we may not be effective in policing unauthorized use of our intellectual property and authorized uses may not have the intended effect. Even when we do detect violations, we have in the past and may in the future need to engage in litigation or licensing to enforce our intellectual property rights. Any enforcement efforts we undertake, including litigation, could be time-consuming and expensive and could divert our management’s attention. In addition, our efforts may be met with defenses and counterclaims challenging the validity and enforceability of our intellectual property rights or may result in a court determining that our intellectual property rights are unenforceable. The legal framework surrounding protection of intellectual property changes frequently throughout the world, particularly as to technologies used in e-commerce, and these changes may impact our ability to protect our intellectual property and defend against third party claims. If we are unable to cost-effectively protect our intellectual property rights, our business could be harmed.

We may experience fluctuations in our tax obligations and effective tax rate.

We are subject to a variety of taxes and tax collection obligations in the United States and in numerous other foreign jurisdictions. We record tax expense, including indirect taxes, based on current tax payments and our estimates of future tax payments, which may include reserves for estimates of probable or likely settlements of tax audits. We may recognize additional tax expense and be subject to additional tax liabilities, including tax collection obligations, due to changes in tax law, such as digital services taxes, or online sales taxes. In 2021, the administration of President Joseph R. Biden, as well as several members of Congress, through the fiscal budget reconciliation process, released proposed legislation that includes several significant modifications to key income tax provisions, as well as introduced new provisions, to the U.S. internal revenue code. The proposed legislation includes, among other things, an increase to the U.S. federal income tax rate, generally to between 25% to 28% from the current 21% tax rate, an increase to U.S. tax on foreign earnings, an increase to the limitation of deductible interest expense, and an increase to the disallowance of a deduction for certain named executive officers’ compensation. Although it is uncertain if some or all of the identified provisions will be enacted, a change in U.S. tax law would likely materially and adversely impact our income tax liability, deferred tax asset or liability balances, provision for income taxes, and effective tax rate. We may also be subject to increased requirements for marketplaces to report, collect, remit, and hold liability for their customers’ direct and indirect tax obligations, or as a result of changes to regulations, administrative practices, outcomes of court cases, and changes to the global tax framework. Our effective tax rate and cash taxes paid in a given financial statement period may be adversely impacted by results of our business operations including changes in the mix of revenue among different jurisdictions, acquisitions, investments, entry into new geographies, the relative amount of foreign earnings, changes in foreign currency exchanges rates, changes in our stock price, intercompany transactions, changes to accounting rules, expectation of future profits, changes in our deferred tax assets and liabilities and our assessment of their realizability, and changes to our ownership or capital structure. Fluctuations in our tax obligations and effective tax rate could adversely affect our business.

In the ordinary course of our business, there are numerous transactions and calculations for which the ultimate tax determination is uncertain. Although we believe that our tax positions and related provisions reflected in the financial statements are fully supportable, we recognize that these tax positions and related provisions may be challenged by various tax authorities. These tax positions and related provisions are reviewed on an ongoing basis and are adjusted as additional facts and information become available, including progress on tax audits, changes in interpretation of tax laws, developments in case law, and closing of statute of limitations. To the extent that the ultimate results differ from our original or adjusted estimates, our effective tax rate can be adversely affected.

The provision for income taxes involves a significant amount of management judgment regarding interpretation of relevant facts and laws in the jurisdictions in which we operate. Future changes in applicable laws, projected levels of taxable income and tax planning could change the effective tax rate and tax balances recorded by us. In addition, tax authorities periodically review income tax returns filed by us and can raise issues regarding its filing positions, timing and amount of income and deductions, and the allocation of income among the jurisdictions in which we operate. A significant period of time may elapse between the filing of an income tax return and the ultimate resolution of an issue raised by a revenue authority with respect to that return. Any adjustments as a result of any examination, may result in additional taxes or penalties against us. If the ultimate result of these audits differs from original or adjusted estimates, they could have a material impact on our effective tax rate and tax liabilities.

At any one time, multiple tax years could be subject to audit by various taxing jurisdictions. As a result, we could be subject to higher than anticipated tax liabilities as well as ongoing variability in our quarterly tax rates as audits close and exposures are re-evaluated.

The terms of our debt instruments may restrict our ability to pursue our business strategies.

We do not currently have any obligations outstanding under our credit facility. While the indentures governing our outstanding convertible notes do not include material restrictions on our ability to pursue our business strategy, our credit facility requires us to comply with, and future debt instruments may require us to comply with, various covenants that limit our ability to take actions such as:

•disposing of assets;

•completing mergers or acquisitions;

•incurring additional indebtedness;

•encumbering our properties or assets;

•paying dividends, making other distributions or repurchasing our common stock;

•making specified investments; and

•engaging in transactions with our affiliates.

65

Table of Contents

These restrictions could limit our ability to pursue our business strategies. If we default under our credit facility and if the default is not cured or waived, the lenders could terminate their commitments to lend to us and cause any amounts outstanding to be payable immediately. Such a default could also result in cross defaults under other debt instruments. Moreover, any such default would limit our ability to obtain additional financing, which may have an adverse effect on our cash flow and liquidity.

Our insurance may not cover or mitigate all the risks facing our business.

While we have insurance coverage for most aspects of our business risk, this insurance coverage may be incomplete or inadequate, or in some cases may not be available. Our business has evolving risks that may be unpredictable. For certain risks we face, we may be required to, or may elect to, self-insure or rely on insurance held by third parties, legal defenses and immunities, indemnification agreements or limits on liability, which may be insufficient.

For example, we may not have adequate insurance coverage related to the actions of sellers on our platforms. In evolving areas such as platform products liability, recent decisions such as McMillan v. Amazon in Texas, and Loomis v. Amazon and Bolger v. Amazon in California, suggest that different jurisdictions may take differing positions on the scope of e-commerce platform liability for seller products. In some circumstances, a platform might be held liable for violations of applicable legal regimes by sellers and their products, such as intellectual property laws, privacy and security laws, product regulation, or consumer protection laws. Court decisions and regulatory changes in these areas may shift quickly, both in the United States and worldwide, and our insurance may be inadequate or unavailable to protect us from existing or newly developing legal risks. Finally, while some sellers on our platforms may be insured for some or all of these risks, many small businesses do not carry any or sufficient insurance, and, even if a seller is insured, the insurance may not cover the relevant loss.

These factors may lead to increased costs for insurance, our increased liability, increased liability or requirements on sellers on our platforms, changes to our marketplaces or business model, or other damage to our brands and reputation.

Strategic Risks Related to Our Business and Industry

We face intense competition and may not be able to compete effectively.

Operating e-commerce marketplaces is highly competitive and we expect competition to increase in the future. To be successful, we need to attract and retain sellers and buyers. As a result, we face competition from a wide range of online and offline competitors.

We compete for sellers with marketplaces, retailers, social media commerce, and companies that sell software and services to small businesses. For example, in addition to listing her goods for sale on the Etsy marketplace, a seller can list her goods with online retailers, such as Amazon, eBay, Google, or Alibaba, or sell her goods through local consignment and vintage stores and other venues or marketplaces, including through commerce channels on social networks like Facebook, Instagram, and TikTok. She may also sell wholesale directly to traditional retailers, including large national retailers, who discover her goods in our marketplaces or otherwise. We similarly compete for sellers on our other marketplaces, Depop, Reverb, and Elo7, which sellers may list their goods with online retailers such as Vinted, ThredUp, or Poshmark, in the case of Depop, Sweetwater, in the case of Reverb, or MercadoLibre, in the case of Elo7, among others, or sell through other venues, marketplaces, retailers, or commerce channels.

We also compete with companies that sell software and services to small businesses, enabling a seller to sell from her own website or otherwise run her business independently of our platforms, or enabling her to sell through multiple channels, such as BigCommerce, Wix, and Shopify.

We compete to attract, engage, and retain sellers based on many factors, including:

•the value and awareness of our brands;

•effectiveness of our marketing;

•the global scale of our marketplaces and the breadth of our online presence;

•our tools, education, and services, which support a seller in running her business;

•the number and engagement of buyers;

•our policies and fees;

•the ability of a seller to scale her business;

•the effectiveness of our mobile apps;

66

Table of Contents

•the strength of our communities; and

•our mission.

In addition, we compete with retailers for the attention of buyers. A buyer has the choice of shopping with any online or offline retailer, including large e-commerce marketplaces, such as Amazon, eBay, or Alibaba, national retail chains, such as West Elm, Walmart, or Target, local consignment and vintage stores, social commerce channels like Instagram or Facebook, event-driven platforms and vertical experiences like Zola and Wayfair, resale commerce and streaming video commerce sites and apps, and other venues or marketplaces. Many of these competitors offer low-cost or free shipping, fast shipping times, favorable return policies, and other features that may be difficult or impossible for our sellers to match. As pandemic-related restrictions on movement continue to ease, competition may intensify as buyers return to traditional brick and mortar retail stores.

We compete to attract, engage, and retain buyers based on many factors, including:

•the breadth and quality of items that sellers list in our marketplaces;

•the ease of finding items;

•the value and awareness of our brands;

•the person-to-person commerce experience;

•customer service;

•our reputation for trustworthiness;

•the effectiveness of our mobile apps;

•the availability of timely, fair, and free shipping offered by sellers to buyers;

•ease of payment;

•localization and experiences targeted based on regional preferences, and

•the availability and reliability of our platforms.

Many of our competitors and potential competitors have longer operating histories, greater resources, better name recognition, or more customers than we do. They may invest more to develop and promote their services than we do, and they may offer lower fees to sellers than we do. Large, widely adopted platforms may benefit from significant user bases, access to user or industry-wide data, the ability to unilaterally set policies and standards, and control over complementary services such as fulfillment, advertising or on-platform apps or e-commerce transactions. To the extent Etsy and our sellers may rely on these competitors’ services, such services may be integrated into site functionality, and these competitors may have access to substantial data about Etsy and its communities of buyers and sellers. As a result, they may have the ability to reduce our ability to service our users, reduce our ability to obtain analytics or information to optimize advertising or intentionally seek to disintermediate Etsy.

We believe that it is, and that it should continue to be, relatively easy for new businesses to create online commerce offerings or tools or services that enable entrepreneurship. However, as the technology space is increasingly subject to regulation, there is a risk that legislation, and regulatory or competition inquiries, even if focused on large, widely adopted platforms, may inadvertently impede smaller platforms and small businesses, including us and our sellers. For example, legislation and inquiries may result in obligations with which only large platforms are situated to comply. If legislation or regulatory inquiries, even if focused on other entities, requires us to expend significant resources in response or results in the imposition of new obligations, our business and results of operations could be adversely affected.

Local companies or more established companies based in markets where we operate outside of the United States may also have a better understanding of local customs, providing them a competitive advantage. For example, in certain markets outside the United States, we compete with smaller, but similar, local online marketplaces with a focus on unique goods that are attempting to attract sellers and buyers in those markets.

If we are unable to compete successfully, or if competing successfully requires us to expend significant resources in response to our competitors’ actions, our business and results of operations could be adversely affected.

Depop’s growth and profitability depends on its ability to attract new buyers and sellers, expand internationally and to compete effectively in new and existing markets.

Depop provides an online platform for resale of used and vintage apparel and accessories. To grow GMS and profitability, Depop must grow its active seller and buyer communities in the United States and the United Kingdom, expand into new geographies, and compete effectively in the increasingly competitive resale sector.

The markets for resale and secondhand items are highly competitive. In addition, Depop competes with vendors of new and secondhand items, including branded goods stores, local, national, and global department stores, traditional brick-and-mortar consignment and thrift stores, specialty retailers, direct-to-consumer retailers, discount chains, independent retail stores, the online offerings of traditional retail competitors, and resale sellers specializing in niche or narrow categories, as well as online marketplaces that may offer the same or similar goods and services that Depop offers. Competitors offering secondhand apparel include other online marketplaces, such as eBay, Vinted, ThredUp, Poshmark, and The RealReal; large online and traditional retailers such as Amazon, H&M, Kohl’s, and Walmart; and off-price retailers, such as Burlington Stores, Ross Stores, and The TJX Companies. We believe Depop’s ability to compete depends on many factors, many of which are beyond its control, including:

•attracting and retaining active buyers and sellers and increasing the volume of secondhand items they buy and sell;

•sellers offering a broad selection of desirable and high-quality secondhand items on Depop’s marketplace;

•continuing appeal of secondhand fashion to Gen Z and other demographics;

•growing favorable brand recognition in new and existing markets;

•the speed and cost at which Depop sellers ship purchased items to buyers; and

•the ease with which Depop buyers and sellers can purchase, supply, and return secondhand items.

As resale markets continue to evolve and expand, we anticipate competition in this sector to increase. Moreover, consumer preferences may change, or growth in consumer demand for used items may decelerate or even decrease, and buyers may not purchase through Depop’s marketplace as frequently or spend as much with Depop sellers as they have historically. Relatedly, an inability to attract and retain buyers could harm our ability to attract and retain sellers, who may decide to resell their items through alternative platforms or marketplaces.

If we are not able to keep pace with technological changes and enhance our current offerings and develop new offerings to respond to the changing needs of sellers and buyers, our business, financial performance, and growth may be harmed.

Our industry is characterized by rapidly changing technology, new service and product introductions, and changing customer demands and preferences, and we are not able to predict the effect of these changes on our business. The technologies that we currently use to support our platforms may become inadequate or obsolete, and the cost of incorporating new technologies into our products and services may be substantial. Our sellers and buyers, however, may not be satisfied with our enhancements or new offerings or may perceive that these offerings do not respond to their needs or create value for them. Additionally, as we invest in and experiment with new offerings or changes to our platforms, our sellers and buyers may find these changes to be disruptive and may perceive them negatively. In addition, developing new services and features is complex, and the timetable for public launch is difficult to predict and may vary from our historical experience. As a result, the introduction of new offerings may occur after anticipated release dates, or they may be introduced as pilot programs, which may not be continued for various reasons. In addition, new offerings may not be successful due to defects or errors, negative publicity, or our failure to market them effectively.

New offerings may not drive GMS or revenue growth, may require substantial investment and planning, and may bring us more directly into competition with companies that are better established or have greater resources than we do.

If we do not continue to cost-effectively develop new offerings that satisfy sellers and buyers, then our competitive position and growth prospects may be harmed. In addition, new offerings may not drive the GMS or revenue that we anticipate, may have lower margins than we anticipate or than existing offerings, and our revenue from the new offerings may not be enough to offset the cost of developing and maintaining them, which could adversely affect our business, financial performance, and growth.

If the widely adopted mobile, social, search, and/or advertising solutions that we, our sellers and our buyers rely on as part of our key offering are no longer available or effective, or if access to these major platforms is limited, the use of our marketplaces could decline.

We are dependent on widely-adopted third party platforms to reach our customers, such as popular mobile, social, search, and advertising offerings. If we are not able to deliver a rewarding experience on these platforms, or if our or our sellers’ access to these platforms is limited, or if these large platforms implement features that compete with us or our sellers, then our products and marketing efforts may suffer, and our sellers’ ability to manage and scale their business may be harmed. In addition, we may not be able to deliver a rewarding experience, we may have limited access to, or we may be unable to invest significant time and resources towards, integration with and offering our services through new or updated devices, operating system versions, social networks, or search platforms (including Internet of Things (“IoT”) based or voice based platforms). If our solutions and integrations are ineffective or unavailable, then our products and marketing efforts may suffer, and our sellers’ ability to manage and scale their business may be harmed. As a consequence, our sellers may choose to sell elsewhere, and our business may suffer.

Conversion rates differ between web, mobile web, and mobile app traffic. If visits to our platforms from sources with lower conversion rates (such as mobile web for the Etsy.com marketplace) were to increase as a percentage of overall visits, it could adversely impact our conversion rate and reduce GMS on our platforms which could adversely affect our business, financial performance, and growth.

The success of our marketplaces could also be harmed by factors outside our control, such as actions taken by providers of mobile and desktop operating systems, social networks, or search and advertising platforms, including:

•policy changes that interfere with, add tolls to, or otherwise limit our ability to provide users with a full experience of our platforms, such as for our mobile apps or social network presence;

•unfavorable treatment received by our platforms, especially as compared to competing platforms, such as the placement of our mobile apps in a mobile app download store;

•increased costs to distribute or use our platforms via mobile apps, social networks, or established search and advertising systems;

•changes in mobile operating systems, such as iOS and Android, that degrade the functionality of our mobile website or mobile apps or that give preferential treatment to competitive products;

•changes to social networks that degrade the e-commerce functionality, features, or marketing of us or our sellers’ shops and products; or

•implementation and interpretation of regulatory or industry standards by these widely adopted platforms that, as a side effect, degrade the e-commerce functionality, features, or marketing of us or our sellers’ shops and products.

If sellers and buyers encounter difficulty accessing or using our marketplaces through these widely adopted access providers, our business, financial performance, and growth may be adversely affected.

Expanding our operations outside of the United States is part of our strategy and the growth of our business could be harmed if our expansion efforts do not succeed.

We are focused on growing our business both inside and outside of the United States. Although we have a significant number of sellers and buyers outside of the United States, we are a U.S.-based company with less experience developing local markets internationally and may not execute our strategy successfully. Operating outside of the United States also requires significant management attention, including managing operations and people over diverse geographic areas with varying cultural norms and customs, and adapting our platforms and business operations to local markets.

Our ability to grow our international operations may also be adversely affected by any circumstances that reduce or hinder cross-border trade. For example, the shipping of goods cross-border is typically more expensive and slower than domestic shipping and often involves complex customs and duty inspections and the dependency of national postal carrier systems. If jurisdictions become increasingly fragmented, with additional regulation of small sellers and platforms, tariffs, certifications, representative requirements, and customs requirements that increase the cost or complexity of cross-border trade, whether on the seller’s sourcing of materials or between the seller and buyer, our business could be adversely impacted. In addition, varying quarantines, closures, delayed or terminated delivery services, and movement restrictions related to the ongoing COVID-19 pandemic may interfere with our international growth strategy.

Our success outside the United States also depends upon our ability to attract sellers and buyers from the same countries in order to enable the growth of local markets. An inability to develop our communities globally or to otherwise grow our business outside of the United States in a cost-effective manner could adversely affect our GMS, revenue, and operating results.

Competition is also likely to intensify outside of the United States, both where we operate now and where we plan to expand. Local companies based outside the United States may have a substantial competitive advantage because of their greater understanding of, and focus on, their local markets, along with regulations that may favor local companies. Some of our competitors may also be able to develop and grow internationally more quickly than we will.

Despite our execution efforts, the goods that sellers list on our Etsy and Reverb marketplaces may not appeal to non-U.S. consumers in the same way as they do to consumers in the United States. In addition, non-U.S. buyers are not as familiar with the Etsy and Reverb brands as buyers in the United States and may not perceive us as relevant or trustworthy. Also, visits to our Etsy and Reverb marketplaces from buyers outside the United States may not convert into sales as often as visits from within the United States, including due to the impact of a strong U.S. dollar relative to other currencies and the fact that most of the goods listed on these platforms are denominated in U.S. dollars. Similarly, non-U.K. consumers may be less familiar with Depop, or find the listed items less appealing, than consumers in the United Kingdom and non-Brazilian consumers may be less familiar with Elo7, or find the listed items less appealing, than consumers in Brazil.

Continued international expansion may also require significant financial investment. For example, Etsy has made initial investments to explore growth opportunities in India, a dynamic market where we have limited operating experience and acquired Elo7 which extends Etsy’s reach in Latin America. To facilitate continued international expansion, we plan to invest in seller and buyer acquisition marketing, enhancing our machine translation and machine learning to help sellers and buyers connect even if they do not speak the same language, forming relationships with third-party service providers, supporting operations in multiple countries, and potentially acquiring additional companies based outside the United States and integrating those companies with our operations. Our investment outside of the United States may be more costly than we expect or unsuccessful.

Our recent acquisitions of Depop and Elo7 may create strains on our management, technology and operational resources and may prove to be costlier and take longer to integrate than we anticipate which may ultimately reduce or eliminate the benefits to Etsy of the acquisitions.

We expect that our acquisitions of Depop and Elo7 will continue to require significant attention and resources from our management team and workforce, including our technology, operations, accounting, and human resource units. Devoting resources to the integration of Depop and Elo7 means that these resources will be redeployed to varying degrees from their normal day-to-day activities supporting existing Etsy functions. This could impair our effectiveness and efficiency in serving existing Etsy sellers and buyers and may have an adverse impact on our financial condition or results of operations. For example, to the extent our products and marketing teams are involved in supporting Depop and Elo7, they may be unable to devote sufficient time to product and marketing efforts relating to the Etsy.com and Reverb marketplaces which may materially impact our business, growth, or results of operations.

We incurred substantial transaction fees and costs in connection with our acquisitions of Depop and Elo7 and may experience difficulty in realizing the expected benefits of the acquisitions.

We incurred significant non-recurring expenses in connection with our acquisition of Depop and, to a lesser extent, our acquisition of Elo7, including legal, accounting, filing, financial advisory, and integration planning and other expenses. Additionally, while we intend to operate Depop and Elo7 as stand-alone marketplaces, we may continue to incur significant expenses as we invest to grow their respective businesses and implement public company compliance policies and procedures (including effective internal control over financial reporting and disclosure controls and procedures, as well as information privacy controls).

Also, the success of the Depop and Elo7 acquisitions will depend, in part, on our ability to apply Etsy’s technological, marketing, and operational expertise to help scale their growth in a profitable, efficient, and effective manner, including maintaining relationships with their respective sellers, buyers, and third party service providers. Because our business and the Depop and Elo7 businesses differ in certain respects, we may not be able to manage these businesses smoothly or successfully and may experience difficulty in realizing the expected benefits of the acquisitions.

Potential difficulties that may be encountered include the following:

•the loss of key employees;

•challenges in executing on Depop’s and Elo7’s business plans; and

•potential unknown liabilities, unforeseen expenses, and other complexities associated with integrating Depop and Elo7 into and managing our “House of Brands.”

If we are unable to successfully integrate Depop and Elo7 into our “House of Brands” strategy, we may be unable to realize the benefits we expect to achieve as a result of these acquisitions. As a result, our business, growth and/or results of operations could be adversely affected.

We may have limited redress with respect to claims under the Depop and Elo7 acquisition agreements.

The agreements pursuant to which we acquired Depop and Elo7 contain representations, warranties, and covenants that are customary for transactions of their nature, as well as limitations on the obligations and liabilities of the former equityholders of Depop and Elo7, as applicable, including in the case of the Depop acquisition, no recourse directly against Depop’s former shareholders for a breach of the business-related representations and warranties. In connection with the Depop acquisition, we have obtained customary representation and warranty insurance to insure against losses that may arise from breaches of certain representation and warranties included in the Depop acquisition agreement, which policy is itself subject to specified limitations and exclusions. There can be no assurance that, in the event of a claim made in connection with the Depop acquisition, the policy would cover the relevant losses, nor can there be any assurance that the proceeds that are recoverable under the policy (if any), in the case of the Depop acquisition, or the proceeds that are recoverable from the indemnity escrow, in the case of the Elo7 acquisition, would be sufficient to compensate us for any losses incurred. Therefore, we may have no or limited recourse with respect to claims for breach of the representations, warranties, covenants, or other provisions contained in the Depop and Elo7 acquisition agreements which could adversely affect our financial condition and results of operations.

The due diligence undertaken by us in connection with the Depop and Elo7 acquisitions may not have revealed all relevant considerations or liabilities of Depop and/or Elo7, which could have an adverse effect on our financial condition or results of operations.

Although we conducted due diligence in connection with our acquisitions of Depop and Elo7, we cannot assure you that this due diligence revealed all relevant facts necessary to fully evaluate Depop and Elo7. Furthermore, the information provided during due diligence may have been incomplete, inadequate, or inaccurate. As part of each due diligence process and our evaluation of the relevant opportunity, we also made subjective judgments regarding the results of operations, financial condition, and prospects of Depop and Elo7. If the due diligence investigation failed to correctly or completely identify material issues and liabilities that may be present in Depop or Elo7, or if we considered certain risks to be commercially acceptable relative to the respective opportunity, we may incur substantial, unexpected, or greater than anticipated expense should such issues, liabilities, or risks materialize. In addition, we may be subject to significant, previously undisclosed liabilities of Depop and Elo7 that were not identified during due diligence and that could contribute to poor financial or operational performance and have an adverse effect on our financial condition and results of operations.

We may expand our business through additional acquisitions of other businesses or assets or strategic partnerships and investments, which may divert management’s attention and/or prove to be unsuccessful.

We have acquired a number of businesses in the past, including our recent acquisitions of Depop and Elo7 in July 2021, and may acquire additional businesses or technologies, or enter into strategic partnerships, in the future. We may not realize the anticipated benefits of our acquisitions or any partnerships, and possible future acquisitions or relationships may disrupt our business and divert management’s time and attention. Acquisitions also may require us to spend a substantial portion of our available cash, issue stock, incur debt or other liabilities, amortize expenses related to intangible assets, or incur write-offs of goodwill or other assets. In addition, integrating an acquired business or technology is risky. Any future acquisitions or partnerships may result in unforeseen operational difficulties and expenditures associated with:

•integrating new businesses and technologies into our infrastructure;

•clearing any required regulatory review that may be complex, costly, time consuming, or place additional requirements on the business;

•implementing growth initiatives;

•integrating administrative functions;

•hiring, retaining, and integrating key employees;

•supporting and enhancing morale and culture;

•retaining key customers, merchants, vendors, and other key business partners;

•maintaining or developing controls, procedures, and policies (including effective internal control over financial reporting and disclosure controls and procedures, as well as information privacy controls); and

•assuming liabilities related to the activities of the acquired business before and after the acquisition, including liabilities for violations of laws and regulations, intellectual property infringement, commercial disputes, cyber attacks, taxes, and other matters.

We also may issue additional equity securities in connection with an acquisition or partnership, which could cause dilution to our stockholders. Finally, acquisitions or partnerships could be viewed negatively by analysts, investors, or the members of our communities.

Our marketing efforts to help grow our business may not be effective.

Maintaining and promoting awareness of our marketplaces and services is important to our ability to attract and retain sellers and buyers. One of the key parts of our strategy for the Etsy marketplace is to bring more new buyers to the marketplace and create more habitual buyers by inspiring more frequent purchases across multiple categories and purchase occasions. We continue to iterate on and invest in our marketing strategies, which may not succeed for a variety of reasons, including our inability to execute and implement our plans.

Our marketing efforts currently include search engine optimization, search engine marketing, affiliate marketing, display advertising, as well as social media, mobile push notifications, and email marketing. If we fail to scale and deliver an effective return on investment in any of these marketing efforts, it may harm our business. We also engage with celebrities and influencers as part of our marketing efforts, and our perceived affiliation with these individuals could cause us brand or reputational damage in the event they undertake actions inconsistent with our brands and values.

Additionally, we invest significantly in brand advertising via channels such as television and digital video advertising. If we do not produce effective content or purchase effective air time and placement for that content, it could fail to deliver a return on our investment, and damage our brands and/or business. Many of our marketing efforts include our sellers and products from their shops selected via automated systems. These automated systems may not always operate effectively. While both our manual and automated systems have tools and procedures designed to account for our and our partners’ policies, despite our best efforts, we may inadvertently include in our marketing efforts sellers or their products inconsistent with our policies, brands and values, which could result in failure to deliver a return on our investment, media or regulatory scrutiny, and damage to our brands and/or business.

We obtain a significant number of visits via search engines such as Google. Search engines frequently change the algorithms that determine the ranking and display of results of a user’s search, alter analytics or search engine optimization data available to us or make other changes to the way results are displayed, which can negatively affect the placement of links to our marketplaces and reduce the number of visits or otherwise negatively impact our marketing efforts.

We also obtain a significant number of visits from social media platforms such as Facebook, Instagram, and Pinterest. Search engines, social networks, and other third parties typically require compliance with their policies and procedures, which may be subject to change or new interpretation with limited ability to negotiate, which could negatively impact our marketing capabilities (including marketing services for our sellers), GMS, and revenue. Etsy-provided controls for users to limit third party advertising features, the growing use of online ad-blocking software and technological changes to browsers and mobile operating systems, impact the effectiveness of, or our visibility and insights into, our marketing efforts. As a result, we may fail to bring more buyers, or fail to increase frequency of visits to our platforms. In addition, ongoing legal and regulatory changes in the data privacy sphere, such as the E.U. General Data Protection Regulation (“GDPR”), the California Consumer Privacy Act of 2018 (“CCPA”), the California Privacy Rights Act of 2020 (“CPRA”), and additional laws being passed or considered in U.S. States and countries throughout the world may impact the scope and effectiveness of marketing and advertising services generally, including those used on our platforms.

We also obtain a significant number of visits through email marketing. If we are unable to successfully deliver emails to our sellers and buyers, if our email subscription tools do not function correctly, or if our sellers and buyers do not open our emails, whether by choice, because those emails are marked as low priority or spam, or for other reasons, our business could be adversely affected. As e-commerce, search, and social networking, as well as related regulatory regimes, evolve, we must continue to evolve our marketing tactics and technology accordingly and, if we are unable to do so, our business could be adversely affected.

Some providers of consumer devices, mobile or desktop operating systems, and web browsers have implemented, or have announced plans to implement, ways to block tracking technologies which, if widely adopted, could also result in online tracking methods becoming significantly less effective. Similarly, our vendors, particularly those providing advertising and analytics products and services have, and may continue to, modify their products and services based on legal and technical changes relating to privacy in ways that could reduce the efficiency of our marketing efforts and our access to data about use of our platforms. Any reduction in our ability to make effective use of such technologies could harm our ability to personalize the experience of buyers, increase our costs, and limit our ability to attract and retain our sellers and buyers on cost-effective terms. As a result, our business and results of operations could be adversely affected.

Enforcement of our marketplace policies may negatively impact our brands, reputation, and/or our financial performance.

We maintain and enforce policies that outline expectations for users while they engage with our services, whether as a seller, a buyer, or a third party and expect to maintain and enforce similar policies at Depop and Elo7 once we have integrated Depop and Elo7 into our marketplace policy program. Additionally, we prohibit a range of items on our marketplaces, including (but not limited to): drugs, alcohol, tobacco, weapons, endangered animal products, hazardous materials, recalled items or those that create an unreasonable risk of harm, highly-regulated items, items violating intellectual property rights of others, illegal products, pornography, items from federally-sanctioned jurisdictions, hateful content, and items that promote or glorify violence.

We enforce these policies in order to uphold the safety and integrity of our marketplaces, engender trust in the use of our services, and encourage positive connections among members of our communities. We strive to enforce these policies in a consistent and principled manner that is transparent and explicable to stakeholders. However, even with a principled and objective approach, policy enforcement is a combination of human and technological review. As a result, there could be errors, it could be subject to different, inconsistent, or conflicting regional consensus or regulatory standards in different jurisdictions, or it could be perceived to be arbitrary, unclear, or inconsistent. Similarly, the tools and processes in place with respect to Etsy’s recently acquired marketplaces, Elo7 and Depop, are not as sophisticated or mature as those used by Etsy. Shortcomings and errors in our ability to enforce our policies across our marketplaces could lead to negative public perception, distrust from our members, or lack of confidence in the use of our services, and could negatively impact the reputation of our brands. In particular, certain enforcement decisions, even those we deem necessary for the health and safety of our marketplaces, may be received negatively by stakeholders or the public, such as:

•we may choose to limit or prohibit the sale of items in our marketplaces based on our policies, even though we could benefit financially from the sale of those items;

•from time to time, we may revise our policies in ways that we believe will enhance trust in our platforms, even though the changes may be perceived unfavorably, such as updates to the way we define handmade.

We are subject to risks related to our environmental, social and governance activities and disclosures.

We have developed an Impact strategy that focuses on leveraging Etsy’s core business to generate value for our communities and stakeholders through positive economic, social, and ecological efforts (our “ESG metrics”). Our Impact strategy aims to create more economic opportunity for our stakeholders, ensure equitable access to the opportunities we create, and build long-term resilience by fostering responsible resource use and reducing our carbon footprint. We have also elected to publicly share these ESG metrics and include them in the Annual Report, and, as a result, our business may face heightened scrutiny for these activities. See “Business—Our Impact Strategy and Progress” in the Annual Report. While selected metrics receive limited assurance from an independent third party, this is inherently a less rigorous process than reasonable assurance sought in connection with a financial statement audit and such review process may not identify errors and may not protect us from potential liability under the securities laws.

If we do not demonstrate progress against our Impact strategy or if our Impact strategy is not perceived to be adequate, our reputation could be harmed. We could also damage our reputation and the value of our brands if we fail to act responsibly in the areas in which we report and demonstrate that our commitment to our Impact strategy enhances our overall financial performance.

Any harm to our reputation resulting from setting these metrics or our failure or perceived failure to meet such metrics could impact employee engagement and retention, the willingness of our buyers and sellers and our partners and vendors to do business with us, or investors’ willingness to purchase or hold shares of our common stock, any of which could adversely affect our business, financial performance, and growth.

If we are unable to successfully execute on our business strategy or if our strategy proves to be ineffective, our business, financial performance, and growth could be adversely affected.

Our ability to execute our strategy, including our “House of Brands” strategy, is dependent on a number of factors, including the ability of our senior management team and key team leaders to execute the strategy, our ability to iterate in a rapidly evolving e-commerce landscape, maintain our pace of product experiments coupled with the success of such initiatives, our ability to meet the changing needs of our sellers and buyers, and the ability of our employees to perform at a high level. If we are unable to execute our strategy, if our strategy does not drive the growth that we anticipate, if the public perception is that we are not executing on our strategy, or if our market opportunity is not as large as we have estimated, it could adversely affect our business, financial performance, and growth.

We may need additional capital, which may not be available to us on acceptable terms or at all.

We believe that our existing cash and cash equivalents and short-term investments (including the proceeds from the 2021 Notes offering), together with cash generated from operations, after giving effect to the funding of our acquisitions of Depop and Elo7 from existing cash and investment balances, will be enough to meet our anticipated cash needs for at least the next 12 months. However, we may require additional cash resources due to changes in business conditions or other developments, such as acquisitions or investments we may decide to pursue. We may seek to borrow funds under our credit facility or sell additional equity or debt securities. The sale of additional equity or convertible debt securities could result in dilution to our existing stockholders. Any debt financing that we may secure in the future could result in additional operating and financial covenants that would limit or restrict our ability to take certain actions, such as incurring additional debt, making capital expenditures, repurchasing our stock, or declaring dividends. It is also possible that financing may not be available to us in amounts or on terms acceptable to us, if at all. Weakness and volatility in capital markets and the economy in general could limit our access to capital markets and increase our costs of borrowing.

We have a significant amount of debt and may incur additional debt in the future. We may not have sufficient cash flow from our business to pay our substantial debt when due.

Our ability to pay our debt when due or to refinance our indebtedness, including the 0% Convertible Senior Notes due 2023 we issued in March 2018 (the “2018 Notes”), the 0.125% Convertible Senior Notes due 2026 we issued in September 2019 (the “2019 Notes”), the 0.125% Convertible Senior Notes due 2027 we issued in August 2020 (the “2020 Notes”) and the 0.25% Convertible Senior Notes due 2028 we issued in June 2021 (the “2021 Notes” and together with the 2018 Notes, the 2019 Notes, and the 2020 Notes, the “Notes”), depends on our future performance, which is subject to economic, financial, competitive, and other factors beyond our control. Our business may not continue to 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 equity capital on terms that may be onerous or highly dilutive. In addition, any required repurchase of the Notes for cash as a result of a fundamental change would lower our current cash on hand such that we would not have those funds available for use in our business or could require us to obtain additional financing to fund the repurchase. Our ability to refinance our 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. Based on the daily closing prices of our stock during the quarter ended September 30, 2021, holders of the 2018 Notes and the 2019 Notes are eligible to convert their 2018 Notes and 2019 Notes, as applicable, during the fourth quarter of 2021. See “Note 8—Debt” in the Notes to Consolidated Financial Statements for more information on the 2018 Notes and 2019 Notes.

In addition, we and our subsidiaries may be able to incur substantial additional debt in the future, subject to the restrictions contained in our debt instruments, some of which may be secured debt. If, for example, we incur additional debt, secure existing or future debt, or recapitalize our debt, these actions may diminish our ability to make payments on our substantial debt when due.

Regulatory, Compliance, and Legal Risks

Failure to deal effectively with constantly evolving fraud or other illegal activity could harm our business.

We have adopted policies and procedures that are intended to ensure compliance with law, including, for example anti-corruption, anti-money laundering, export control, and trade sanctions requirements, and we have measures in place to detect and limit the occurrence of fraudulent and other illegal activity in our marketplaces, however, those policies, procedures, and measures may not always be effective. Further, the measures that we use to detect and limit the occurrence of fraudulent and other illegal activity must be dynamic and require significant investment and resources, particularly as our marketplaces increase in public visibility and size. Bad actors constantly apply continually evolving technologies and ways to commit fraud and other illegal activity, and regulations requiring marketplaces to detect and limit these activities are increasing. Our measures may not always keep up with these changes. If we fail to limit the impact of illegal activity in our marketplaces, we could be subject to penalties, fines, other enforcement actions and/or significant expenses and our business, reputation, financial performance, and growth could be adversely affected.

We rely upon third-party service providers to perform certain compliance services. If we or our service providers do not perform adequately, our compliance tools may not be effective, which could increase our expenses, lead to potential legal liability, and negatively impact our business.

Our brands may be harmed if third parties or members of our communities use or attempt to use our marketplaces as part of their illegal or unethical business practices.

Our emphasis on our mission and guiding principles makes our reputation particularly sensitive to allegations of illegal or unethical business practices by our sellers or other members of our communities. Our seller policies promote legal and ethical business practices. Etsy expects sellers to work only with manufacturers who comply with all applicable laws, who do not use child or involuntary labor, who do not discriminate, and who promote sustainability and humane working conditions. We also expect our suppliers to comply with our Supplier Code of Conduct. We expect that once we fully integrate Depop and Elo7 into our supply chain management program, Depop and Elo7 suppliers will also be subject to the Supplier Code of Conduct. Although we seek to influence, we do not directly control our sellers, suppliers, or other members of our communities or their business practices, and cannot ensure that they comply with our policies. If members of our communities engage in illegal or unethical business practices, or are perceived to do so, we may receive negative publicity and our reputation may be harmed.

We may be subject to claims that items listed by sellers in our marketplaces are counterfeit, infringing, illegal, harmful or otherwise violate our policies.

We frequently receive communications alleging that items listed in our marketplaces infringe upon third-party copyrights, trademarks, patents, or other intellectual property rights. We have intellectual property complaint and take-down procedures in place to address these communications, and we believe such procedures are important to promote confidence in our marketplaces, along with both proactive and reactive anti-counterfeiting measures that we use and continue to develop. We follow these procedures to review complaints and relevant facts to determine the appropriate action, which may include removal of the item from our marketplaces and, in certain cases, closing the shops of sellers who violate our policies.

Our procedures may not effectively reduce or eliminate our liability. For example, on the Etsy marketplace we use a combination of automatic and manual tools and depend upon human review in many circumstances. No tools and procedures are guaranteed to function completely without error, particularly for physical, non-standardized goods, our tools and procedures may be subject to error or enforcement failures and may not be adequately staffed, and we may be subject to an increasing number of erroneous or fraudulent demands to remove content. In addition, we may be subject to civil or criminal liability for activities carried out by sellers on our platforms, especially outside the United States where laws may offer less protection for intermediaries and platforms than the United States.

Under current U.S. copyright laws such as the Digital Millennium Copyright Act § 512 et. seq., we benefit from statutory safe harbor provisions that protect us from copyright liability for content posted on our platforms by sellers and buyers, and we rely upon user content platform protections under 47 U.S.C. § 230 (commonly referred to as CDA § 230), that limits most non-intellectual property law claims against Etsy based upon content posted by users on our platforms. However, trademark and patent laws do not include similar statutory provisions, and limits on platform liability for these forms of intellectual property are primarily based upon court decisions. Similarly, laws related to product liability vary by jurisdiction, and the liability of marketplace platforms for products and services of sellers, while traditionally limited, is subject to increasing debate in courts, legislatures and legislative proposals, and with regulators. These safe harbors and court rulings, including analogous ones in other state and international jurisdictions, have and may change unfavorably. Moreover, changes focused on actions by very large platforms that perform retailer-like functions, or handle mass user content, may directly or indirectly also impact us, our sellers, buyers and vendors.

Proposed laws in Europe and the United States may change the scope of platform liability, and ongoing case law developments may unpredictably increase our liability as platforms for user activity. In that event, we may be held directly or secondarily liable for the intellectual property infringement, product compliance deficiencies, consumer protection deficiencies, privacy and data protection incidents, or regulatory issues of our sellers, including potentially for their conduct over which we have no control or influence.

Regardless of the validity of any claims made against us, we may incur significant costs and efforts to defend against or settle them. If a governmental authority determines that we have aided and abetted the infringement or sale of counterfeit, harmful or unlawful goods or if legal changes result in us potentially being liable for actions by sellers on our platforms, we could face regulatory, civil, or criminal penalties. As in the past, claims by third-party rights owners could require us to pay damages or refrain from permitting any further listing of the relevant items. These types of claims could seek substantial damages or force us to modify our business practices, which could lower our revenue, increase our costs, or make our platforms less user-friendly. These claims, or legal and regulatory changes, could require the removal of non-infringing, lawful or completely unrelated content, which could negatively impact our business and our ability to retain sellers. Moreover, public perception that unlicensed, counterfeit, harmful or unlawful items are commonly offered by sellers in our marketplaces, even if factually incorrect, could result in negative publicity and damage to our reputation.

We have been involved in, and in the future may be involved in, litigation and regulatory matters that are expensive and time consuming and that may require changes to our strategy, the features of our platforms and/or how our business operates.

In addition to intellectual property claims, we have been involved in other litigation and regulatory matters, including matters related to consumer protection, product liability, security and privacy, commercial, or shareholder derivative lawsuits, either individually or, where available, on a class-action basis. We have been and may in the future be subject to heightened regulatory scrutiny, inquiries, or investigations, including with respect to our sellers, vendors or third parties, relating to both specific inquiries as well as broad, industry-wide concerns, such as antitrust, product liability, and privacy, that could lead to increased expenses or reputational damage. For example, while we have stated on our Etsy marketplace platform that items offered by sellers on Etsy, such as masks and hand sanitizers, are not medical-grade, and that our sellers cannot make substantive medical or health claims, we may nevertheless be subject to claims based in whole or in part on the actions of sellers in violation of that directive.

Under certain circumstances, we have contractual and other legal obligations to indemnify and to incur legal expenses on behalf of current and former directors, officers, and underwriters. Any lawsuit or regulatory action to which we are a party, with or without merit, may result in an unfavorable judgment. We have in the past settled lawsuits and regulatory actions and may decide in the future to settle lawsuits or regulatory actions, even if non-meritorious. Any such settlements may be on unfavorable terms. Any such negative outcome could result in payments of substantial damages or fines, damage to our reputation, or adverse changes to our offerings or business practices. Any of these results could adversely affect our business. In addition, defending claims is costly and can impose a significant burden on our management.

We limit certain claims against us under our Terms of Use, including through requirements for arbitration, limits on class actions, limitations of liability, venue selection, and indemnification requirements. These requirements may be subject to differing interpretations and legal frameworks in different U.S. federal, state, and foreign jurisdiction courts, and may have reduced or no enforceability in some jurisdictions. Where these claim limitations are unavailable to us, it could significantly increase our costs, require significant resources across multiple jurisdictions, result in complex or inconsistent decisions, and subject us to forum shopping by third parties seeking jurisdictions amenable to their claims.

Lawsuits or other enforcement actions brought against us have resulted in settlements, and may result in injunctions, damages, fines, or penalties, which could have a material adverse effect on our financial condition or results of operations or require changes to our business. Although we establish accruals for our litigation and regulatory matters in accordance with applicable accounting guidance when those matters proceed to a stage where they present loss contingencies that are both probable and reasonably estimable, there may be a material exposure to loss in excess of any amounts accrued, or in excess of any loss contingencies disclosed as reasonably possible, particularly in more uncertain legal or regulatory environments. Such loss contingencies may not be probable and reasonably estimable until the proceedings have progressed significantly, which could take several years and occur close to resolution of the matter.

Expanding and evolving regulations in the areas of privacy and user data protection could create technological, economic and complex cross-border business impediments to our business and those of our sellers.

We collect, receive, store, process, generate, use, transfer, disclose, make accessible, protect, secure, dispose of, and share personal information, confidential information and other potentially protected information necessary to provide our service, to operate our business, for legal and marketing purposes, and for other business-related purposes.

Data protection has become a significant issue in the United States, countries in the European Union, and in many other countries in which we operate. In addition to the actual and potential changes in law described elsewhere in these Risk Factors, global developments in privacy and data security regulations are changing some of the ways we, our sellers, our vendors and other third parties collect, use, and share personal information and other proprietary or confidential information. Compliance with these changing regulations have necessitated some specific product changes for our non-U.S. activities, and required additional compliance obligations for us and for our relationships with sellers, vendors, and other third parties.

In the European Union, the GDPR contains strict requirements for processing the personally identifiable information of individuals residing in the European Economic Area (“EEA”), Switzerland and (in a form frozen as of December 31, 2020 and as further separately domestically amended), the United Kingdom. The GDPR seeks to harmonize the data protection regulations throughout these jurisdictions. The regulation contains numerous requirements and changes from previous E.U. law, including more robust obligations on data processors, greater rights for data subjects (requiring potentially significant changes to both our technology and operations), security and accountability obligations, and significantly heavier documentation and record-keeping requirements for data protection compliance programs. Specifically, the GDPR introduced numerous privacy-related changes for companies operating in the European Union, including greater control over personal data by data subjects (e.g., the “right to be forgotten”), increased data portability, access, and redress rights for E.U. consumers, data breach notification requirements, increased rules for online and email marketing, compliance requirements related to our sellers, vendors and third parties, and stronger regulatory enforcement regimes. The GDPR is subject to changing interpretations due to decisions of data protection authorities, courts, and related legislative efforts both E.U.-wide and in particular jurisdictions. The GDPR requirements apply to some third-party transactions (such as commercial contracts with partners and vendors) and to transfers of information

76

Table of Contents

between us and our subsidiaries, including user and employee information. GDPR requirements may also apply, depending on interpretation of its reach, to some users in our worldwide communities of sellers. We may experience difficulty retaining or obtaining new E.U. sellers, or current and new sellers may limit their selling into the European Union, due to the legal requirements, compliance cost, potential risk exposure, and uncertainty for them in respect of their own compliance obligations with respect to GDPR. In addition, although our sellers are independent businesses, it is possible that a privacy authority could deem us jointly and severally liable for actions of our sellers or vendors, which would increase our potential liability exposure and costs of compliance, which could negatively impact our business. We could face potential liability, regulatory investigation, and costly litigation, which may not be adequately covered by insurance.

In the United States, rules and regulations governing data privacy and security include those promulgated under the authority of the Federal Trade Commission Act, the Electronic Communications Privacy Act, the Computer Fraud and Abuse Act, California’s CCPA (effective January 1, 2020) and CPRA (effective January 1, 2023), and other state and federal laws relating to privacy, consumer protection, and data security. The CCPA and CPRA introduce new requirements regarding the handling of personal information of California consumers and households, including compliance and record keeping obligations, the right to request access to and deletion of their personal information, and the right to opt out of the sale of their personal information and provides a private right of action and statutory damages for data breaches.

Other jurisdictions in the United States are beginning to expand existing regulations, or propose laws similar to the CCPA. If more stringent privacy legislation arises in the United States, it could increase our potential liability and adversely affect our business, results of operations, and financial condition. Additionally, other countries outside of Europe have enacted or are considering enacting similar cross-border data transfer restrictions and laws requiring local data residency, and strict limitations to the processing of personal information, which could increase the cost and complexity of delivering our services and operating our business. In the past year, for example, Brazil enacted the General Data Protection Law, New Zealand enacted the New Zealand Privacy Act, China released its draft Personal Information Protection Law, and Canada introduced the Digital Charter Implementation Act.

GDPR, CCPA, and similar laws coming into effect in other jurisdictions may continue to change the data protection landscape globally, may be potentially inconsistent or incompatible, and could result in potentially significant operational costs for internal compliance and risk to our business. Some of these requirements introduce friction into the buying and selling experience on our platforms and may impact the scope and effectiveness of our marketing efforts, which could negatively impact our business and future outlook. Beyond GDPR and CCPA/CPRA, individual jurisdictions continue to pass laws related to data protection, such as data privacy and data breach notification, resulting in a diverse set of requirements across states, countries, and regions. Non-compliance with these laws could result in proceedings against us by one or more data protection authorities, other public authorities, third parties, or individuals. Under GDPR alone, noncompliance could result in fines of up to 20 million Euros or up to 4% of the annual global revenue of the noncompliant company, whichever is greater. We may not be entirely successful in our compliance efforts due to various factors either within our control (such as limited internal resource allocation) or outside our control (such as a lack of vendor cooperation, new regulatory interpretations, or lack of regulatory guidance in respect of certain GDPR requirements).

In addition, E.U. data protection laws, including the GDPR, also generally prohibit the transfer of personal information from Europe to the United States and most other countries unless the recipient country has been deemed to have adequate privacy protections in place to protect the personal information. Parties transferring protected personal data to jurisdictions deemed inadequate must establish a legal basis for, and implement specific safeguards for, such intra-party or inter-party transfers. A recent judgment of the Court of Justice of the European Union found a common basis for such transfers, the E.U.-U.S. Privacy Shield, insufficient, and a parallel arrangement with Switzerland may similarly be deemed insufficient. While Etsy did not rely upon Privacy Shield for cross-border transfers, Reverb previously had done so. While effective solutions may be available to permit these transfers, such as Standard Contractual Clauses (“SCCs”), continuing changes to the rules related to cross-border transfers may nonetheless impede Etsy and its subsidiaries’ ability to effectively transfer data between jurisdictions with parties such as partners, vendors and users, or may make such transfers of personal data more costly. In particular, another recent decision and related European Commission guidance and updates to the SCCs may impose additional obligations on companies seeking to rely on the SCCs and may require significant expense and resources associated with compliance. Transfers by us or our vendors of personal information from Europe pursuant to SCCs may not comply with E.U. data protection law, may increase our exposure to the GDPR’s heightened sanctions for violations of its cross-border data transfer restrictions, and may result in lower sales on our platforms because of difficulty of establishing a lawful basis for personal information transfers out of Europe.

We also publish privacy policies and other documentation regarding our collection, processing, use, and disclosure of personal data. Although we endeavor to comply with our published policies and documentation, we may at times fail to do so or may be perceived to have failed to do so. Moreover, despite our efforts, we may not be successful in achieving compliance, such as if our employees or vendors fail to comply with our published policies and documentation. We are subject to occasional requests from regulators regarding these efforts. Failures can subject us to potential international, local, state, and federal action under both data protection and consumer protection laws. We are or may also be subject to the terms of our own and third party external and internal privacy and security policies, codes, representations, certifications, industry standards, publications and frameworks and contractual obligations to third parties related to privacy, information security, including contractual obligations to indemnify and hold harmless third parties from the costs or consequences of non-compliance with data protection laws, or other obligations.

Our sellers and vendors may have been and may in the future be subject to similar privacy requirements, which may significantly increase costs and resources dedicated to their compliance with such requirements. We have varying contractual and other legal obligations to notify relevant stakeholders of security breaches related to us or, in some cases, our third-party service providers. Many jurisdictions have enacted laws requiring companies to notify individuals, regulatory authorities, and others of security breaches involving certain types of data in some circumstances. In addition, our agreements with certain stakeholders may require us to notify them in the event of such a security breach. Such mandatory disclosures, even if only related to actions of a third-party vendor, are costly, could lead to negative publicity, may cause members of our communities to lose confidence in the effectiveness of our security measures and require us to expend significant capital and other resources to respond to and/or alleviate problems caused by the actual or perceived security breach, and may cause us to breach customer contracts. Our contracts, our representations or industry standards, to varying extents, require us to use industry-standard or reasonable measures to safeguard sensitive personal information or confidential information. A cyber incident or security breach could lead to claims by members of our communities, or other relevant stakeholders that we have failed to comply with such legal or contractual obligations. As a result, we could be subject to legal action or members of our communities could end their relationships with us. There can be no assurance that any indemnifications, limitations of liability or other remedies in our contracts would be enforceable or adequate or would otherwise protect us from liabilities or damages.

We may not have adequate insurance coverage for security incidents or breaches, including fines, judgments, settlements, penalties, costs, attorney fees, and other impacts that arise out of incidents or breaches. If the impacts of a security incident or breach, or the successful assertion of one or more large claims against us that exceeds our available insurance coverage, is of a type not subject to insurance, or results in changes to our insurance policies (including premium increases or the imposition of large deductible or co-insurance requirements), it could have an adverse effect on our business. In addition, we cannot be sure that our existing insurance coverage, cyber coverage, and coverage for errors and omissions will continue to be available on acceptable terms or that our insurers will not deny coverage as to all or part of any future claim or loss. Our risks are likely to increase as we continue to expand, grow our customer base, and process, store, and transmit increasingly large amounts of proprietary and sensitive data.

Expanding our operations in Latin America and India may expose us to additional risks.

We recently acquired Elo7 which currently operates principally in Brazil and we additionally recently opened offices in Mexico and India. Each of these jurisdictions has legal framework, regulatory environment, and culture that differs materially from those of North America and Europe where our operations have historically been located. In addition, the timing and impact of the COVID-19 pandemic has been materially different from jurisdiction to jurisdiction. If we are unable to manage these risks, it could adversely affect our business, financial performance, and growth. Further, the success of our Elo7 marketplace may be adversely affected by macroeconomic, social, and political conditions prevailing in Brazil and Latin America. Decreases in the growth rate, periods of negative growth, increases in inflation, persistent deflation, changes in law, regulation, policy, or future judicial rulings and interpretations of policies involving exchange and capital controls and other matters such as (but not limited to) currency depreciation, foreign exchange regulations, inflation, interest rates, taxation, employment and labor laws, banking laws, and regulations and other political, economic, or regulatory developments in or affecting Brazil and/or other parts of Latin America may affect the overall business environment and may, in turn, adversely impact Elo7’s financial condition and results of operations in the future or create obstacles to the successful integration of Elo7 into Etsy.

Our business and our sellers and buyers may be subject to evolving sales and other tax regimes in various jurisdictions, which may harm our business.

The application of indirect taxes, such as sales and use tax, value-added tax, provincial tax, goods and services tax, business tax, withholding tax, digital service tax, gross receipt tax, and tax information reporting obligations to businesses like ours and to our sellers and buyers is a complex and evolving issue. Significant judgment is required to evaluate applicable tax obligations and as a result amounts recorded are estimates and are subject to adjustments. In many cases, the ultimate tax determination is uncertain because it is not clear when and how new and existing statutes might apply to our business or to our sellers’ businesses. In some cases it may be difficult or impossible for us to validate information provided to us by our sellers on which we must rely to ascertain any obligations that may apply to us related to our sellers’ businesses, given the intricate nature of these regulations as they apply to particular products or services and that many of the products and services sold in our marketplace are unique or handmade. If we are found to be deficient in how we have addressed our tax obligations, our business could be adversely impacted.

Various jurisdictions (including the U.S. states and E.U. member states) are seeking to, or have recently imposed additional reporting, record-keeping, indirect tax collection and remittance obligations, or revenue-based taxes on businesses like ours that facilitate online commerce. For example, the recently enacted American Rescue Plan Act of 2021 included a provision which significantly increases the number of sellers for whom we must report payment transactions. If requirements like these become applicable in additional jurisdictions, our business, collectively with our sellers’ businesses, could be harmed. For example, taxing authorities in many U.S. states and in other countries have targeted e-commerce platforms as a means to calculate, collect, and remit indirect taxes for transactions taking place over the internet, and have enacted laws and others are considering similar legislation. Such changes to current law or new legislation could adversely affect our business if the requirement of tax to be charged on items sold on our marketplaces causes our marketplaces to be less attractive to current and prospective buyers,

78

Table of Contents

which could materially impact our business and our sellers’ businesses. This legislation could also require us or our sellers to incur substantial costs in order to comply, including costs associated with tax calculation, collection, remittance, and audit requirements, which could make selling on our marketplaces less attractive. Additionally, the European Union, certain member states, and other countries have proposed or enacted taxes on online advertising and marketplace service revenues. Our results of operations and cash flows could be adversely affected by additional taxes of this nature imposed on us prospectively or retroactively or additional taxes or penalties resulting from the failure to provide information about our buyers, sellers, and other third parties for tax reporting purposes to various authorities. In some cases, we also may not have sufficient notice to enable us to build solutions and adopt processes to properly comply with new reporting or collection obligations by the applicable effective date.

Our business is subject to a large number of U.S. and non-U.S. laws, many of which are evolving.

We are subject to a variety of laws and regulations in the United States and around the world, including those relating to traditional businesses, such as employment laws and taxation, and laws and regulations focused on e-commerce and online marketplaces, such as online payments, privacy, anti-spam, data security and protection, online platform liability, marketplace seller regulation, intellectual property, product liability, and consumer protection. In light of our international operations, we need to comply with various laws associated with doing business outside of the United States, including anti-money laundering, sanctions, anti-corruption, and export control laws. In some cases, non-U.S. privacy, data security, consumer protection, e-commerce, and other laws and regulations are more detailed or comprehensive than those in the United States and, in some countries, are actively enforced.

These laws and regulations are continuously evolving, and compliance is costly and can require changes to our business practices and significant management time and effort. In some jurisdictions, these laws and regulations may be subject to attempts to apply such domestic rules world-wide against Etsy or its subsidiaries, and occasionally may subject us to inconsistent obligations across jurisdictions.

Additionally, it is not always clear how existing laws apply to online marketplaces as many of these laws do not address the unique issues raised by online marketplaces or e-commerce. For example, as described elsewhere in these Risk Factors, laws relating to privacy are evolving differently in different jurisdictions. Federal, state, and non-U.S. governmental authorities, as well as courts interpreting the laws, continue to evaluate and assess the privacy requirements that are applicable to Etsy and its marketplaces.

New platform liability laws, potential amendments to existing laws, and ongoing regulatory and judicial interpretation of these laws imparting liability for conduct by users of a platform may create costs and uncertainty for both Etsy and sellers on our platforms. This may even be the case for new laws or regulations focused on other technology areas, business practices, or other third parties that nonetheless indirectly or unintentionally impact us, our sellers, or our vendors. For example, the European Union’s recent e-Copyright in the Digital Single Market Directive and Platform to Business Regulation, and pending Digital Services Act (DSA) and Digital Markets Act (DMA), may impact us directly, as well as impacting our sellers and vendors. Similarly, recently adopted anti-waste regulations in Germany and France may directly impact our sellers, as well as impose compliance verification obligations on us. If we and our sellers are unable to cost-effectively comply with new regulatory regimes, such as if the regulations place requirements on our sellers that they find difficult or impossible to comply with, or require us to take actions at a scale inconsistent with the size, investment, and operation of our marketplaces, our sellers may elect not to ship into, or we may be required to restrict shipping into, the impacted jurisdictions, and our business could be harmed. In addition, there have been various Congressional efforts to require platforms to vet and police sellers, restrict the scope of the protections available to online platforms for third party user content under intellectual property laws such as the Digital Millennium Copyright Act § 512 et seq., or limit user content platform protections under 47 U.S.C. § 230 (commonly referred to as CDA § 230). As a result, our current protections from liability for third-party content in the United States could significantly decrease or change. We could incur significant costs implementing required changes, investigating and defending claims and, if we are found liable, significant damages.

We also operate under an increasing number of regulatory regimes protecting us and our sellers and buyers worldwide, such as intellectual property and anti-counterfeiting laws, payments and taxation, competition, marketplace platform regulation, hate speech laws, and general commerce regulation. For example, upcoming regulations may impose significant verification, certification or ongoing compliance hurdles on both us and our sellers. These laws, and court or regulatory interpretations of these laws, may shift quickly in the United States and worldwide. We may not have the resources or scale to effectively adapt to and comply with any changes to these regulatory regimes which may limit our ability to take advantage of the protections these regimes offer. In addition, some of these changes may be at least partially inconsistent with how our platforms operate, especially if they are adopted in the context of, or in a manner best suited for, larger platforms, which may make it harder for us to utilize these regimes to protect our marketplaces. If we are unable to cost-effectively protect our platforms, sellers and buyers under these regulatory regimes, such as if the regulations place requirements on our sellers that they find difficult or impossible to comply with, limit the functions or features our marketplaces can offer, or require us to take actions at a scale inconsistent with the size, investment, and operation of our marketplaces, our business could be harmed.

Existing and future laws and regulations enacted by federal, state, or non-U.S. governments or the inconsistent enforcement of such laws and regulations could impede the growth of e-commerce or online marketplaces, which could have a negative impact

79

on our business and operations. Examples include data localization requirements, limitation on marketplace scope or ownership, intellectual property intermediary liability rules, regulation of online speech, limits on network neutrality, packaging and recycling requirements, seller certification and representative requirements, and rules related to security, privacy, or national security, which may impede us, our users, or our vendors. We could also face regulatory challenges or be subject to allegations of discriminatory or anti-competitive practices that could impede both our and our sellers’ growth prospects, increase our costs, and harm our business. We may be subject to regulatory requests for information or testimony related to regulatory challenges of third parties, such as our competitors or our vendors, which could cause us to incur significant costs and expend significant resources in response, and could impact our relationship with those third parties.

We strive to comply with all applicable laws, but they may conflict with each other, and by complying with the laws or regulations of one jurisdiction, we may find that we are violating the laws or regulations of another jurisdiction. Despite our efforts, we may not have fully complied in the past and may not fully comply in the future, particularly where the applicable regulatory regimes have not been broadly interpreted. If we become liable under laws or regulations applicable to us, we could be required to pay significant fines and penalties, our reputation may be harmed, and we may be forced to change the way we operate. That could require us to incur significant expenses or to discontinue certain services, which could negatively affect our business.

Additionally, if third parties with whom we work violate applicable laws or our policies, those violations could result in other liabilities for us and could harm our business. Our ability to rely on insurance, or indemnification and other contractual remedies to limit these liabilities, may be insufficient or unavailable in some cases. Furthermore, the circumstances in which we may be held liable for the acts, omissions, or responsibilities of our sellers is uncertain, complex, and evolving. For example, certain laws have recently been enacted seeking to hold marketplaces like ours responsible for certain compliance obligations for which sellers have traditionally been responsible. If an increasing number of such laws are passed, the resulting compliance costs and potential liability risk could negatively impact our business.

We may be subject to intellectual property claims, which, even if untrue, could be extremely costly to defend, damage our brands, require us to pay significant damages, and limit our ability to use certain technologies in the future.

Companies in the internet and technology industries are frequently subject to litigation based on allegations of infringement or other violations of intellectual property rights. We periodically receive communications that claim we have infringed, misappropriated, or misused others’ intellectual property rights. To the extent we gain greater public recognition and scale worldwide, we may face a higher risk of being the subject of intellectual property claims. Third parties may have intellectual property rights that they claim cover significant aspects of our technologies or business methods and prevent us from expanding our offerings. Third parties may also allege a company is secondarily liable for intellectual property infringement, or that it is a joint infringer with another party, including claims that Etsy is liable, either directly, indirectly, or vicariously, for infringement claims against sellers using Etsy’s platforms, our vendors, or other third parties, and that statutory, judicial, or other immunities and defenses do not protect us. Any intellectual property claim against us, with or without merit, have been and could in the future be time consuming and expensive to settle or litigate and could divert the attention of our management. Litigation regarding intellectual property rights is inherently uncertain due to the complex issues involved, and we may not be successful in defending ourselves in such matters. For claims against us, insurance may be insufficient or unavailable, and for claims related to actions of third parties, either indemnification or remedies against those parties may be insufficient or unavailable.

Some of our competitors have extensive portfolios of issued patents. Many potential litigants, including some of our competitors, patent holding companies, and other intellectual property rights holders, have the ability to dedicate substantial resources to enforcing their perceived intellectual property rights. Any claims successfully brought directly against us, or implicating us as part of an action against third parties, such as our sellers or vendors, could subject us to significant liability for damages, and we may be required to stop using technology or other intellectual property alleged to be in violation of a third party’s rights in one or more jurisdictions where we do business. We have been and might in the future be required to seek a license for third-party intellectual property. Even if a license is available, we could be required to pay significant royalties or submit to unreasonable terms, which would increase our operating expenses. We may also be required to develop alternative non-infringing technology, which could require significant time and expense. If we cannot license or develop technology for any allegedly infringing aspect of our business, we would be forced to limit our service and may be unable to compete effectively. Any of these results could harm our business.

We are subject to the terms of open source licenses because our platforms incorporate, and we contribute to, open source software, potentially impairing our ability to adequately protect our intellectual property.

The software powering our platforms incorporates software covered by open source licenses. In addition, we regularly contribute source code to open source software projects and release internal software projects under open source licenses, and we anticipate doing so in the future. The terms of many open source licenses relied upon by us and the internet and technology industries have been interpreted by only a few court decisions and there is a risk that the licenses could be construed in a manner that imposes unanticipated conditions or restrictions on our ability to operate our marketplaces. Under certain open source licenses, if certain conditions were met, we could be required to publicly release aspects of the source code of our software or to make our software available under open source licenses.

80

Table of Contents

To avoid the public release of the affected portions of our source code, we could be required to expend substantial time and resources to re-engineer some or all of our software. In addition, use of open source software can lead to greater risks than use of third-party commercial software because open source licensors generally do not provide warranties or controls on the origin of the software. Use of open source software may also present additional security risks because the public availability of such software may make it easier for hackers and other third parties to determine how to compromise our platforms, and availability of patches or fixes may not be consistent or quickly available, as it may be subject to the continued community engagement in a particular open source project. Additionally, because any software source code we contribute to open source projects is publicly available, while we may benefit from the contributions of others, our ability to protect our intellectual property rights in such software source code may be limited or lost entirely, and we will be unable to prevent our competitors or others from using such contributed software source code. Similarly, we may be subject to third party intellectual property claims as a user of or contributor to such open source software. Any of these risks could be difficult to eliminate or manage and, if not addressed, could adversely affect our business, financial performance, and growth.

There remains pronounced legal, economic and implementation uncertainty surrounding the United Kingdom’s departure from the European Union, which may be a source of instability in international markets, create significant currency fluctuations, adversely affect our operations in the United Kingdom, and pose additional risks to our business, revenue and financial condition.

On January 1, 2021, the United Kingdom left the E.U. single market and customs union (“Brexit”). While the United Kingdom and the European Union have agreed to the terms of the United Kingdom’s departure in a trade agreement, there remains a continued lack of clarity about future U.K. laws and regulations as the United Kingdom determines which E.U. rules and regulations to replace or replicate, including financial and banking laws and regulations, tax and free trade agreements, intellectual property rights, supply chain logistics, packaging and recycling rules, privacy and information security laws, payments regulations, environmental, health, and safety laws and regulations, immigration laws, product safety laws, and employment laws, all of which could decrease foreign direct investment in the United Kingdom, increase costs and depress economic activity. Additionally, under the terms of the United Kingdom’s departure, the European Union retains the right to impose tariffs if the United Kingdom violates certain “level playing field” standards relating to working conditions and environmental requirements. The long-term effects of Brexit will depend on how U.K. laws and relationships evolve, as well as the United Kingdom’s adherence to the “level playing field” standards, and how that impacts its ability to negotiate favorable trade agreements with other countries.

The United Kingdom is one of our core markets. We continue to monitor post-Brexit developments so that we may adjust our business and operations as appropriate with the goal of continuing to provide services to our U.K. and E.U. buyers and sellers. A failure by the United Kingdom and the European Union to smoothly implement the trade agreement or to negotiate favorable arrangements governing cross-border services and trade, and ongoing uncertainty with respect to potential divergent regulatory standards, however, could significantly increase friction on cross-border trade involving U.K. buyers and sellers or reduce the number of sellers on our platforms offering products between the United Kingdom and the European Union. It may also result in additional operational, financial, regulatory, and compliance costs to us as well as decreased revenue, all of which could adversely affect our business.

If we are unable to maintain effective internal control over financial reporting, investors may lose confidence in the accuracy of our financial reports.

As a public company, we are required to maintain internal control over financial reporting and to report any material weaknesses in such internal controls. Section 404 of the Sarbanes-Oxley Act requires that we evaluate and determine the effectiveness of our internal control over financial reporting. It also requires our independent registered public accounting firm to attest to our evaluation of our internal controls over financial reporting. Although our management has determined, and our independent registered public accounting firm has attested, that our internal control over financial reporting was effective as of December 31, 2020, we cannot assure you that we or our independent registered public accounting firm will not identify a material weakness in our internal controls in the future.

If we have a material weakness in our internal control over financial reporting in the future, we may not detect errors on a timely basis. If we have difficulty implementing and maintaining effective internal control over financial reporting at businesses that we may acquire, or if we identify a material weakness in our internal control over financial reporting in the future, it could harm our operating results, adversely affect our reputation, cause our stock price to decline, or result in inaccurate financial reporting or material misstatements in our annual or interim financial statements. We could be required to implement expensive and time consuming remedial measures. Further, if there are material weaknesses or failures in our ability to meet any of the requirements related to the maintenance and reporting of our internal controls, such as Section 404 of the Sarbanes-Oxley Act, investors may lose confidence in the accuracy and completeness of our financial reports and that could cause the price of our common stock to decline. We could become subject to investigations by Nasdaq, the SEC or other regulatory authorities, which could require additional management attention and which could adversely affect our business.

In addition, our internal control over financial reporting will not prevent or detect all errors and fraud, and individuals, including employees and contractors, could circumvent such controls. Because of the inherent limitations in all control systems, no

81

evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud will be detected.

Other Risks

The price of our common stock has been and will likely continue to be volatile and declines in the price of common stock could subject us to litigation.

The price of our common stock has been and is likely to continue to be volatile. Some companies that have experienced volatility in the trading price of their stock have been the subject of securities litigation. We have experienced securities class action lawsuits in the past and may experience more such litigation following future periods of volatility or declines in our stock price. Any securities litigation could result in substantial costs and divert our management’s attention and resources, which could adversely affect our business.

For example, since January 1, 2020, our common stock’s daily closing price on Nasdaq has ranged from a low of $31.69 to a high of $252.57 through October 29, 2021. The price of our common stock may fluctuate significantly for numerous reasons, many of which are beyond our control, such as:

•variations in our operating results and other financial and operational metrics, including the key financial and operating metrics disclosed in this Quarterly Report, as well as how those results and metrics compare to analyst and investor expectations;

•forward-looking statements related to our financial guidance or projections, our failure to meet or exceed our financial guidance or projections or changes in our financial guidance or projections;

•failure of analysts to initiate or maintain coverage of our company, changes in their estimates of our operating results or changes in recommendations by analysts that follow our common stock or a negative view of our financial guidance or projections and our failure to meet or exceed the estimates of such analysts;

•entry into or exit from stock market indices;

•announcements of new services or enhancements, strategic alliances or significant agreements or other developments by us or our competitors;

•announcements by us or our competitors of mergers or acquisitions or rumors of such transactions involving us or our competitors;

•the amount and timing of our operating expenses and the success of any cost-savings actions we take;

•changes in our Board of Directors or senior management team;

•disruptions in our marketplaces due to hardware, software or network problems, security breaches, or other issues;

•the strength of the global economy or the economy in the jurisdictions in which we operate, particularly during the current COVID-19 pandemic, currency fluctuations, and market conditions in our industry and those affecting members of our communities;

•the trading activity of our largest stockholders;

•the number of shares of our common stock that are available for public trading;

•litigation or other claims against us;

•stockholder activism;

•the operating performance of other similar companies;

•changes in legal requirements relating to our business; and

•any other factors discussed in this Quarterly Report.

In addition, if the market for technology stocks or the stock market in general experiences a loss of investor confidence, the price of our common stock could decline for reasons unrelated to our business, financial performance, or growth. Stock prices of many internet and technology companies have historically been highly volatile.

Future sales and issuances of our common stock or rights to purchase common stock could result in additional dilution to our stockholders and could cause the price of our common stock to decline.

We may issue additional common stock, convertible securities, or other equity in the future, including as a result of conversion of the outstanding Notes. We also issue common stock to our employees, directors, and other service providers pursuant to our equity incentive plans. Such issuances could be dilutive to investors and could cause the price of our common stock to decline. New investors in such issuances could also receive rights senior to those of current stockholders.

The conversion of some or all of the Notes would dilute the ownership interests of existing stockholders to the extent we deliver shares upon conversion of any of the Notes. Each series of Notes is convertible at the option of their holders prior to their scheduled maturity in the event the conditional conversion features of such series of Notes are triggered. Based on the daily closing prices of our stock during the quarter ended September 30, 2021, holders of the 2018 Notes and the 2019 Notes are eligible to convert their 2018 Notes and 2019 Notes, as applicable, during the fourth quarter of 2021. If one or more holders elect to convert their Notes, unless we elect to satisfy our conversion obligation by delivering solely cash to converting holders of such Notes, we could be required to deliver to them a significant number of shares of our common stock, increasing the number of outstanding shares of our common stock. The issuance of such shares of common stock and any sales in the public market of the common stock issuable upon such conversion of the Notes could adversely affect prevailing market prices of our common stock. See “Note 8—Debt” in the Notes to Consolidated Financial Statements for more information on the Notes.

Our certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, or employees.

Our certificate of incorporation provides 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:

•any derivative action or proceeding brought on our behalf;

•any action asserting a breach of fiduciary duty;

•any action asserting a claim against us arising pursuant to the Delaware General Corporation Law; and

•any action asserting a claim against us that is governed by the internal affairs doctrine.

This provision would not apply to suits brought to enforce a duty or liability created by the Exchange Act. Furthermore, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all such Securities Act actions. Accordingly, both state and federal courts have jurisdiction to entertain such claims. While the Delaware courts have determined that choice of forum provisions are facially valid, a stockholder may nevertheless seek to bring a claim in a venue other than that designated in our exclusive forum provision. In such instance, we would expect to vigorously assert the validity and enforceability of the exclusive forum provision of our certificate of incorporation. This may require significant additional costs associated with resolving such action in other jurisdictions and there can be no assurance that the provisions will be enforced by a court in those other jurisdictions.

This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, or other employees and may discourage these types of lawsuits. Alternatively, if a court were to find the choice of forum provision contained in our certificate of incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions.

Our business could be negatively affected as a result of actions of activist stockholders.

The actions of activist stockholders could adversely affect our business. Specifically, responding to common actions of an activist stockholder, such as requests for special meetings, potential nominations of candidates for election to our Board of Directors, requests to pursue a strategic combination, or other transaction or other special requests, could disrupt our operations, be costly and time-consuming, or divert the attention of our management and employees. In addition, perceived uncertainties as to our future direction in relation to the actions of an activist stockholder may result in the loss of potential business opportunities or the perception that we are unstable as a company, which may make it more difficult to attract and retain qualified employees. Our ability to continue to commit to our mission, guiding principles, and culture may also be questioned, which could impact our ability to attract and retain buyers and sellers. Actions of an activist stockholder may also cause fluctuations in our stock price based on speculative market perceptions or other factors that do not necessarily reflect the underlying fundamentals and prospects of our business.

Our stock repurchases are discretionary and even if effected, they may not achieve the desired objectives.

Our Board of Directors approved a stock repurchase program authorizing us to repurchase up to $250 million of our common stock. In addition, in connection with issuance of the 2021 Notes, our Board of Directors approved the repurchase of $180.0 million of our common stock and we used approximately $180.0 million of the net proceeds from the offering to repurchase approximately 1.1 million shares of our common stock at a purchase price equal to $170.21 (the last reported sale price per share of our common stock on June 8, 2021). There can be no assurance that either the June 2021 stock repurchases or any repurchases pursuant to our stock repurchase program will enhance stockholder value because the market price of our common stock may decline below the levels at which we repurchased such shares. In addition, there is no guarantee that our stock repurchases in the past or in the future will be able to successfully mitigate the dilutive effect of recent and future employee stock option exercises and restricted stock vesting or of any issuance of common stock in connection with the conversion of Notes. The amounts and timing of the repurchases may also be influenced by general market conditions and the prevailing price and trading volumes of our common stock. If our financial condition deteriorates or we decide to use our cash for other purposes, we may suspend repurchase activity at any time.

Anti-takeover provisions in our charter documents and under Delaware law could make an acquisition of our company more difficult, could limit attempts to make changes in our management and could depress the price of our common stock.

Provisions in our certificate of incorporation and bylaws and the Delaware General Corporation Law may have the effect of delaying or preventing a change in control of our company or limiting changes in our management. Among other things, these provisions:

•provide for a classified board of directors so that not all members of our Board of Directors are elected at one time;

•permit our Board of Directors to establish the number of directors and fill any vacancies and newly created directorships;

•provide that directors may only be removed for cause;

•require super-majority voting to amend some provisions in our certificate of incorporation and bylaws;

•authorize the issuance of “blank check” preferred stock that our Board of Directors could use to implement a stockholder rights plan;

•eliminate the ability of our stockholders to call special meetings of stockholders;

•prohibit stockholder action by written consent, which means all stockholder actions must be taken at a meeting of our stockholders;

•provide that our Board of Directors is expressly authorized to amend or repeal any provision of our bylaws; and

•require advance notice for nominations for election to our Board of Directors or for proposing matters that can be acted upon by stockholders at annual stockholder meetings.

These provisions may delay or prevent attempts by our stockholders to replace members of our management by making it more difficult for stockholders to replace members of our Board of Directors, which is responsible for appointing the members of our management. In addition, Section 203 of the Delaware General Corporation Law may delay or prevent a change in control of our company by imposing certain restrictions on mergers, business combinations, and other transactions between us and holders of 15% or more of our common stock.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation and Summary of Significant Accounting Policies

Note 1—Basis of Presentation and Summary of Significant Accounting Policies

Description of Business

Etsy, Inc. (the “Company” or “Etsy”) operates a “House of Brands,” two-sided online marketplaces that connect millions of passionate and creative buyers and sellers. The Company’s primary marketplace, Etsy.com, is the global marketplace for unique and creative goods. The Company generates revenue primarily from transaction, listing, and payments processing fees, and on-site advertising and shipping label services.

Basis of Consolidation

The consolidated financial statements include the accounts of Etsy and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. On July 2, 2021, Etsy acquired all the outstanding shares of Elo7 Serviços de Informática S.A. (“Elo7”) by means of a merger, and on July 12, 2021 Etsy acquired all of the issued share capital of Depop Limited (“Depop”) pursuant to a share purchase. The financial results of Elo7 and Depop have been included in Etsy’s Consolidated Financial Statements from the respective dates of acquisition. See “Note 5—Business Combinations.”

Basis of Presentation

The accompanying unaudited interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and pursuant to the applicable rules and regulations of the Securities and Exchange Commission (“SEC”). The Company has condensed or omitted certain information and notes normally included in complete annual financial statements prepared in accordance with GAAP. These unaudited interim consolidated financial statements should therefore be read in conjunction with the audited consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K filed with the SEC on February 26, 2021 (the “Annual Report”). In the opinion of management, all material adjustments, which are of a normal and recurring nature, necessary for a fair presentation of the results for the periods presented have been reflected in the consolidated financial statements. The results of operations of any interim period are not necessarily indicative of the results of operations for the full annual period or any future period due to seasonal and other factors.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires the Company to make estimates and judgments that affect the amounts reported and disclosed in the consolidated financial statements and accompanying notes. Actual results could differ from these estimates and judgments. The accounting estimates that require management’s most subjective judgments include: stock-based compensation; income taxes, including the estimate of the annual effective tax rate at interim periods and evaluation of uncertain tax positions; purchase price allocations for business combinations and valuation of acquired intangible assets, developed technology, and goodwill. As of September 30, 2021, the effects of the ongoing COVID-19 pandemic and progress towards its abatement on the Company’s business, results of operations, and financial condition continue to evolve. As a result, many of the Company’s estimates and judgments required increased judgment and carry a higher degree of variability and volatility. As additional information becomes available, the Company’s estimates may change materially in future periods.

Stock-Based Compensation

Service based stock options, service based restricted stock units (“RSUs”), and performance based restricted stock units (“PBRSUs”) are awarded to employees, officers, and members of the Company’s Board of Directors. The PBRSUs include financial performance based restricted stock units (“Financial PBRSUs”) and total shareholder return performance based restricted stock units (“TSR PBRSUs”), both of which have performance and service vesting requirements. The Company recognizes forfeitures as they occur.

The Company calculates the fair value of stock options on the date of grant using the Black-Scholes option-pricing model. The fair value of RSUs is measured using the closing price of the Company’s common stock on Nasdaq on the grant date. Additionally, the fair value of the Financial PBRSUs is determined using a probability assessment and the fair value of the TSR PBRSUs with market conditions are determined using a Monte-Carlo simulation model.

For PBRSUs, the Company recognizes stock-based compensation expenses on a straight-line basis over the longer of the derived, explicit, or implicit service period. As of interim and annual reporting periods, the Financial PBRSUs stock-based compensation expense is adjusted based on expected achievement of performance targets, while TSR PBRSUs stock-based compensation expense is not adjusted.

Recently Issued Accounting Pronouncements

In October 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2021-08—Business Combinations (Topic 805)—Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires contract assets and contract liabilities acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with Accounting Standards Codification Topic 606—Revenue from Contracts with Customers (“ASC 606”). Under current GAAP, an acquirer generally recognizes assets acquired and liabilities assumed in a business combination, including contract assets and contract liabilities arising from revenue contracts with customers, at fair value on the acquisition date. This ASU will result in the acquirer recording acquired contract assets and liabilities on the same basis that would have been recorded by the acquiree before the acquisition under ASC 606. The amendments in this ASU do not affect the accounting for other assets or liabilities that may arise from revenue contracts with customers in accordance with ASC 606, such as refund liabilities, or in a business combination, such as customer-related intangible assets and contract-based intangible assets. The new guidance is effective for annual and interim periods beginning after December 15, 2022. Early adoption is permitted, including in interim periods, for any financial statements that have not yet been issued. This update should be applied prospectively to business combinations occurring on or after the effective date of the amendments. The Company is currently evaluating the impact that this new guidance may have on its consolidated financial statements.

Recently Adopted Accounting Pronouncements

In August 2020, the FASB issued ASU 2020-06—Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity's Own Equity (Subtopic 815-40)—Accounting For Convertible Instruments and Contracts in an Entity's Own Equity (“ASU 2020-06”). ASU 2020-06 simplifies accounting for convertible instruments by removing major separation models previously required under GAAP. Consequently, more convertible debt instruments will be reported as a single liability instrument with no separate accounting for embedded conversion features through equity. Without an initial allocation of proceeds to the conversion option, the debt will likely have a lower discount, thereby resulting in less non-cash interest expense through accretion. ASU 2020-06 removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception, which will permit more equity contracts to qualify for it. ASU 2020-06 also simplifies the diluted net income per share calculation in certain areas. The new guidance is effective for annual and interim periods beginning after December 15, 2021, and early adoption is permitted for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. This update permits the use of either the modified retrospective or fully retrospective method of transition.

The Company early adopted this standard, effective as of January 1, 2021, on a modified retrospective basis. The adoption of this standard had a material effect on the Company’s consolidated financial statements. The most significant effects related to the 0.125% Convertible Senior Notes due 2027 (the “2020 Notes”), 0.125% Convertible Senior Notes due 2026 (the “2019 Notes”), and 0% Convertible Senior Notes due 2023 (the “2018 Notes” and together with the 0.25% Convertible Senior Notes due 2028 (the “2021 Notes”), the 2020 Notes, and the 2019 Notes, the “Notes”), and included derecognition of the unamortized debt discount, which was recorded as a direct deduction from the Notes, resulting in an increase in long-term debt, net of approximately $264 million; derecognition of the equity component, which represents the value of the conversion option on the issuance date of the Notes outstanding, resulting in a reduction in additional paid-in capital of approximately $229 million, net of taxes; derecognition of deferred tax liabilities of approximately $63 million; and reversal of the cumulative debt discount recognized as interest expense in the Company’s Consolidated Statements of Operations since the date of issuance of each of the Notes to the period ending December 31, 2020, resulting in a decrease of accumulated deficit of approximately $28 million, net of taxes. The Company also had a reduction in interest expense due to the adoption of ASU 2020-06 as the debt discount has been derecognized and, effective January 1, 2021, there is no amortization of the debt discount. The Company did not incur any impact to liquidity or cash flows. When calculating net income per share of common stock attributable to common stockholders, the Company uses the if-converted method as required under ASU 2020-06 to determine the dilutive effect of the Notes.

Income Tax Disclosure [Abstract]

Income Taxes

Note 3—Income Taxes

The Company’s provision or benefit from income taxes in interim periods is determined using an estimate of the annual effective tax rate, adjusted for discrete items, if any, that are taken into account in the relevant period. Each quarter the Company updates its estimate of the annual effective tax rate, and if its estimated tax rate changes, the Company makes a cumulative adjustment. The estimate of the annual effective income tax rate for the full year is applied to the respective interim period, taking into account year-to-date amounts and projected results for the full year.

The Company’s quarterly tax provision, and its quarterly estimate of the annual effective tax rate, is subject to significant variation due to several factors, including variability in accurately predicting its income or loss before tax and the mix of jurisdictions to which they relate, taxable income or loss in each jurisdiction, changes in its stock price, audit-related developments, acquisitions, changes in its deferred tax assets and liabilities and their valuation, foreign currency gains (losses), changes in statutes, regulations, case law, and administrative practices, principles, and interpretations related to tax, including changes to the global tax framework, competition, and other laws and accounting rules in various jurisdictions, and relative changes of expenses or losses for which tax benefits are not recognized. Additionally, the effective tax rate can be more or less volatile based on the amount of income or loss before tax. For example, the impact of discrete items and non-deductible expenses on the effective tax rate is greater when income before income taxes is lower.

For the nine months ended September 30, 2021, the Company’s effective income tax rate was (1.4)% representing an income tax benefit recorded on net income before tax. The effective tax rate for the nine months ended September 30, 2021 was lower than the U.S. statutory rate of 21% primarily due to excess tax benefits from employee stock-based compensation, the impact from foreign operations that are subject to lower tax rates, and a benefit related to a research and development tax credit, partially offset by state income taxes.

Although management believes its tax positions and related provisions reflected in the consolidated financial statements are fully supportable, it recognizes that these tax positions and related provisions may be challenged by various tax authorities. These tax positions and related provisions are reviewed on an ongoing basis and are adjusted as additional facts and information become available, including progress on tax audits, changes in interpretation of tax laws, developments in case law and closing of statute of limitations. To the extent that the ultimate results differ from the original or adjusted estimates of the Company, the effect will be recorded in the provision for income taxes.

The provision for income taxes involves a significant amount of management judgment regarding interpretation of relevant facts and laws in the jurisdictions in which the Company operates. Future changes in applicable laws, projected levels of taxable income and tax planning could change the effective tax rate and tax balances recorded by the Company. In addition, tax authorities periodically review income tax returns filed by the Company and can raise issues regarding its filing positions, timing and amount of income and deductions, and the allocation of income among the jurisdictions in which the Company operates. A significant period of time may elapse between the filing of an income tax return and the ultimate resolution of an issue raised by a revenue authority with respect to that return. Any adjustments as a result of any examination, may result in additional taxes or penalties against the Company. If the ultimate result of these audits differ from original or adjusted estimates, they could have a material impact on the Company’s tax provision.

The amount of unrecognized tax benefits included in the Consolidated Balance Sheets increased $2.9 million in the nine months ended September 30, 2021, from $23.7 million as of December 31, 2020 to $26.6 million as of September 30, 2021. The total amount of unrecognized tax benefits that, if recognized, would favorably affect the effective tax rate is $25.6 million as of September 30, 2021. Although the timing of the resolution and/or closure of audits is highly uncertain, it is reasonably possible that the balance of gross unrecognized tax benefits could significantly change in the next 12 months. Given the number of years remaining subject to examination and the number of matters being examined, at this time, the Company is unable to estimate the full range of possible adjustments to the balance of gross unrecognized tax benefits.

The Company recognizes interest and/or penalties related to uncertain tax positions in income tax expense.

Business Combination and Asset Acquisition [Abstract]

Business Combinations

Note 5—Business Combinations

Depop Acquisition

On July 12, 2021, the Company acquired all of the outstanding capital stock of Depop, an online global peer-to-peer fashion resale marketplace. The Company believes Depop extends its market opportunity in the high frequency apparel sector, specifically in the fast-growing resale space, and deepens the Company’s reach into the Gen Z consumer. The fair value of consideration transferred of $1.493 billion consisted of: (1) cash consideration paid of $1.479 billion, net of cash acquired, (2) non-cash consideration of $4.8 million representing the portion of the replacement equity awards issued in connection with the acquisition that was associated with services rendered through the date of the acquisition, and (3) $9.2 million holdback pending the finalization of certain purchase price items which were resolved and paid in the fourth quarter of 2021. The portion of the replacement equity awards associated with services rendered post-acquisition will be recorded as post-combination expense on a straight-line basis over the remaining vesting period of the awards. Additionally, deferred consideration awards will be issued to certain Depop executives, which will also be recorded as post-combination expense on a straight-line basis over the three-year mandatory service period associated with the deferred consideration. Neither of these awards was included in the fair value of the consideration transferred. For more information on these awards, see Note 11—Stock-Based Compensation.

The acquisition was accounted for under the acquisition method of accounting. Accordingly, the purchase price was allocated to the assets acquired and liabilities assumed based upon their estimated fair values as of the date of the acquisition. The excess of the purchase price over the estimated fair value of the net assets acquired was recorded as goodwill, which consists largely of assembled workforce, expanded market opportunities, and value creation across the Company’s businesses. The resulting goodwill is not expected to be deductible for tax purposes.

The allocation of the purchase price has been prepared on a preliminary basis and changes to the allocation to certain assets and liabilities, including tax estimates, may be revised as additional information becomes available. The Company will finalize the acquisition accounting within the required measurement period of one year.

Depop Purchase Price Allocation

The following table summarizes the allocation of the purchase price (at fair value) to the assets acquired and liabilities of Depop assumed as of July 12, 2021 (the date of acquisition) (in thousands, except years):

	Preliminary Purchase Price Allocation		Estimated Useful Life (in years)
Current assets	$	4,249
Property and equipment other	1,299		2-5
Developed technology	84,661		5
Trademark	245,657		20
Customer relationships	147,116		13
Goodwill	1,131,099		Indefinite
Current liabilities	(18,878)
Non-current liabilities (1)	(28,097)
Deferred tax liability, net	(74,283)
Total purchase price	$	1,492,823

(1) Non-current liabilities are primarily related to non-income tax related contingency reserves.

Elo7 Acquisition

On July 2, 2021, the Company acquired all the outstanding shares of Elo7 (including Elo7, Ltd. and related subsidiaries entities), by means of a merger, an e-commerce marketplace in Brazil focused on unique, handmade items. The Company sees significant potential in Brazil's e-commerce sector, which is still in early stages of development and fueled by one of the largest economies in the world. The Company believes having a well known local brand will help Etsy, Inc. to better capitalize on this opportunity. The fair value of consideration transferred of $212.1 million consisted of: (1) cash consideration paid of $211.3 million, net of cash acquired, and (2) non-cash consideration of $0.8 million representing the portion of the replacement equity awards issued in connection with the acquisition that was associated with services rendered through the date of the acquisition. The portion of the replacement equity awards associated with services rendered post-acquisition will be recorded as post-combination expense on a straight-line basis over the remaining vesting period of the awards, and were therefore not included in the fair value of the consideration transferred. For more information on these awards, see Note 11—Stock-Based Compensation.

The acquisition was accounted for under the acquisition method of accounting. Accordingly, the purchase price was allocated to the assets acquired and liabilities assumed based upon their estimated fair values as of the date of the acquisition. The excess of the purchase price over the estimated fair value of the net assets acquired was recorded as goodwill, which consists largely of assembled workforce, expanded market opportunities, and value creation across the Company’s businesses. The resulting goodwill is not expected to be deductible for tax purposes.

The allocation of the purchase price has been prepared on a preliminary basis and changes to the allocation to certain assets and liabilities, including tax estimates, may be revised as additional information becomes available. The Company will finalize the acquisition accounting within the required measurement period of one year.

Elo7 Purchase Price Allocation

The following table summarizes the allocation of the purchase price (at fair value) to the assets acquired and liabilities assumed of Elo7 as of July 2, 2021 (the date of acquisition) (in thousands):

	Preliminary Purchase Price Allocation		Estimated Useful Life (in years)
Current assets	$	2,721
Developed technology	12,084		5
Trademark	22,187		15

Current liabilities	(3,406)
Non-current liabilities	(2,691)
Deferred tax liability, net	(22,727)
Total purchase price	$	212,141

Revenue and Earnings

Revenue and net loss were $17.4 million and $26.8 million, respectively, for Depop and Elo7, in the aggregate, from their respective dates of acquisition through September 30, 2021. Acquisition-related expenses are expensed as incurred. They were recorded in general and administrative expenses and were $25.0 million and $35.0 million for the three and nine months ended September 30, 2021, respectively.

Net income	108,781		89,040		332,246		184,423

The pro forma financial information includes adjustments that are directly attributable to the business combinations and are factually supportable. The pro forma adjustments include incremental amortization of intangible and developed technology assets, based on preliminary values of each asset, and remove non-recurring transaction costs directly associated with the acquisition, such as legal and other professional service fees, and the pro forma tax impact for such adjustments. Cost savings or operating synergies expected to result from the acquisition are not included in the pro forma results. For the three and nine months ended September 30, 2021, the pro forma financial information excludes $44.2 million and $58.4 million, respectively, of non-recurring acquisition-related expenses incurred prior to the effective dates of the business combinations. For the nine months ended September 30, 2020, the pro forma financial information includes $1.1 million of non-recurring acquisition-related expenses incurred post effective dates of the business combinations. These pro forma results are illustrative only and not indicative of the actual results of operations that would have been achieved nor are they indicative of future results of operations.

Goodwill

The change in the carrying amount of goodwill from December 31, 2020 to September 30, 2021 is as follows, with the addition primarily due to the acquisitions of Depop and Elo7 (in thousands):

Fair Value Measurements

Note 6—Fair Value Measurements

The Company has characterized its investments in marketable securities, based on the priority of the inputs used to value the investments, into a three-level fair value hierarchy. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1), and lowest priority to unobservable inputs (Level 3). If the inputs used to measure the investments fall within different levels of the hierarchy, the categorization is based on the lowest level input that is significant to the fair value measurement of the investment. Investments recorded in the accompanying Consolidated Balance Sheets are categorized based on the inputs to valuation techniques as follows:

Level 1—These are investments where values are based on unadjusted quoted prices for identical assets in an active market that the Company has the ability to access.

Level 2—These are investments where values are based on quoted market prices in markets that are not active or model derived valuations in which all significant inputs are observable in active markets.

Level 3—These are financial instruments where values are derived from techniques in which one or more significant inputs are unobservable. The Company did not have any Level 3 instruments as of September 30, 2021 and December 31, 2020.

Short- and long-term investments and certain cash equivalents consist of investments in debt securities that are available-for-sale. The following table sets forth the cost, gross unrealized losses, gross unrealized gains, and fair values of the Company’s investments as of the dates indicated (in thousands):

(1)$0.6 million and $39.2 million of money market funds were classified as funds receivable and seller accounts as of September 30, 2021 and December 31, 2020, respectively.

The Company evaluates fair value for each individual security in the investment portfolio. All investments in an unrealized loss position have been in an unrealized loss position for less than 12 months as of September 30, 2021.

The Company typically invests in short- and long-term instruments, including fixed-income funds and U.S. Government and agency securities aligned with the Company’s investment strategy. The maturities of the Company’s non-current marketable debt securities generally range from greater than 12 and up to 37 months.

Disclosure of Fair Values

The Company’s financial instruments that are not measured at fair value in the Consolidated Balance Sheets include the Notes, see “Note 8—Debt.” The Company estimates the fair value of the Notes through inputs that are observable in the market, classified as Level 2 as described above. The following table presents the carrying value and estimated fair value of the Notes as of the dates indicated (in thousands):

	As of September 30, 2021				As of December 31, 2020

	$	2,274,387	$	3,496,516	$	1,064,934	$	1,144,682

(1)Upon adoption of ASU 2020-06 as of January 1, 2021, the carrying value of the Notes increased due to the derecognition of the unamortized debt discount, as described in “Note 1—Basis of Presentation and Summary of Significant Accounting Policies—Recently Adopted Accounting Pronouncements.” The increase in the carrying value of the 2018 Notes was offset by the conversion of $43.9 million of the 2018 Notes in the nine months ended September 30, 2021 (see “Note 8—Debt”).

The carrying value of other financial instruments, including cash, accounts receivable, accounts payable, funds receivable and seller accounts, and funds payable and amounts due to sellers approximate fair value due to the immediate or short-term maturity associated with these instruments.

Debt

Note 8—Debt

2021 Convertible Debt

In June 2021, the Company issued $1.0 billion aggregate principal amount of the 2021 Notes in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”). The net proceeds from the sale of the 2021 Notes were approximately $986.7 million after deducting the initial purchasers’ discount and offering expenses and before the 2021 Capped Call Transactions, as described below, and the repurchase of stock, as described in “Note 10—Stockholders’ Equity.”

The 2021 Notes are convertible into shares of the Company’s common stock based upon an initial conversion rate of 4.0518 shares of the Company’s common stock per $1,000 principal amount of 2021 Notes (equivalent to an initial conversion price of approximately $246.80 per share). The conversion rate will be subject to adjustment upon the occurrence of certain specified events, including certain distributions and dividends to all or substantially all of the holders of the Company’s common stock. Based on the terms of the 2021 Notes, when a conversion notice is received, the Company has the option to pay or deliver cash, shares of the Company’s common stock, or a combination thereof. Accordingly, the Company cannot be required to settle the 2021 Notes in cash and, therefore, the 2021 Notes are classified as long-term debt as of September 30, 2021.

The 2021 Notes will mature on June 15, 2028, unless earlier converted, redeemed, or repurchased. Prior to the close of business on the business day immediately preceding February 15, 2028, holders may convert all or a portion of their 2021 Notes only under the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on September 30, 2021 (and only during such calendar quarter), if the last reported sale price of the Company’s 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 10 consecutive trading day period (the “measurement period”) in which the trading price per $1,000 principal amount of 2021 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 common stock and the conversion rate on each such trading day; (3) if the Company calls the 2021 Notes for redemption at any time prior to the close of business on the second scheduled trading day immediately preceding the redemption date, but only with respect to the 2021 Notes called (or deemed called) for redemption; or (4) upon the occurrence of specified corporate events. On and after February 15, 2028 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their 2021 Notes at any time, regardless of the foregoing circumstances.

The Company may redeem all or any portion of the 2021 Notes, at the Company’s option, subject to partial redemption limitations, on or after June 20, 2025, if the last reported sale price of the Company’s common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive), including the trading day immediately preceding the date on which the Company provides notice of redemption, during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which the Company provides notice of redemption at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date.

If a fundamental change occurs prior to the maturity date, holders may require the Company to repurchase all or a portion of their 2021 Notes for cash at a price equal to 100% of the principal amount of the 2021 Notes to be repurchased. Holders of 2021 Notes who convert their 2021 Notes in connection with a notice of a redemption or a make-whole fundamental change may be entitled to a premium in the form of an increase in the conversion rate of the 2021 Notes. As of September 30, 2021, none of the conditions permitting the holders of the 2021 Notes to early convert have been met.

In accounting for the issuance of the 2021 Notes, the Company recorded the 2021 Notes as a liability at face value. Transaction costs attributable to the liability were recorded as a direct deduction from the related debt liability in the Consolidated Balance Sheet and are amortized to interest expense over the term of the 2021 Notes.

2021 Capped Call Transactions

The Company used $85.0 million of the net proceeds from the 2021 Notes to enter into privately negotiated capped call instruments (“2021 Capped Call Transactions”) with certain financial institutions. The 2021 Capped Call Transactions are expected generally to reduce the potential dilution and/or offset the cash payments the Company is required to make in excess of the principal amount of the 2021 Notes upon conversion of the 2021 Notes in the event that the market price per share of the Company’s common stock is greater than the strike price of the 2021 Capped Call Transactions with such reduction and/or offset subject to a cap. The 2021 Capped Call Transactions have an initial cap price of $340.42 per share of the Company’s common stock, which represents a premium of 100% over the last reported sale price of the Company’s common stock on June 8, 2021, and is subject to certain adjustments under the terms of the 2021 Capped Call Transactions. Collectively, the 2021 Capped Call Transactions cover, initially, the number of shares of the Company’s common stock underlying the 2021 Notes, subject to anti-dilution adjustments substantially similar to those applicable to the 2021 Notes.

The 2021 Capped Call Transactions do not meet the criteria for separate accounting as a derivative as they are indexed to the Company’s stock. The premiums paid for the 2021 Capped Call Transactions have been included as a net reduction to additional paid-in capital within stockholders’ equity.

2020 Convertible Debt

In August 2020, the Company issued $650.0 million aggregate principal amount of the 2020 Notes in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act. The net proceeds from the sale of the 2020 Notes were approximately $639.5 million after deducting the offering expenses. The 2020 Notes are convertible into shares of the Company’s common stock based upon an initial conversion rate of 5.0007 shares of the Company’s common stock per $1,000 principal amount of 2020 Notes (equivalent to an initial conversion price of approximately $199.97 per share). The Company used $74.7 million of the net proceeds from the 2020 Notes offering to enter into separate capped call instruments (“2020 Capped Call Transactions”) with the initial purchasers and/or their respective affiliates.

During any calendar quarter preceding May 1, 2027 in which the closing price of the Company’s common stock exceeds 130% of the applicable conversion price of the 2020 Notes on at least 20 of the last 30 consecutive trading days of the quarter, holders may, in the immediate quarter following, convert all or a portion of their 2020 Notes. Based on the daily closing prices of the Company’s stock during the quarter ended September 30, 2021, holders of the 2020 Notes are not eligible to convert their 2020 Notes during the fourth quarter of 2021. Based on the terms of the 2020 Notes, when a conversion notice is received, the Company has the option to pay or deliver cash, shares of the Company’s common stock, or a combination thereof. Accordingly, the Company cannot be required to settle the 2020 Notes in cash and, therefore, the 2020 Notes are classified as long-term debt as of September 30, 2021.

2019 Convertible Debt

In September 2019, the Company issued $650.0 million aggregate principal amount of the 2019 Notes in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act. The net proceeds from the sale of the 2019 Notes were $639.5 million after deducting the initial purchasers’ discount and offering expenses. The 2019 Notes are convertible based upon an initial conversion rate of 11.4040 shares of the Company’s common stock per $1,000 principal amount of 2019 Notes (equivalent to an initial conversion price of approximately $87.69 per share). The Company used $76.2 million of the net proceeds from the 2019 Notes offering to enter into separate capped call instruments (“2019 Capped Call Transactions”) with the initial purchasers and/or their respective affiliates.

During any calendar quarter preceding June 1, 2026 in which the closing price of the Company’s common stock exceeds 130% of the applicable conversion price of the 2019 Notes on at least 20 of the last 30 consecutive trading days of the quarter, holders may, in the immediate quarter following, convert all or a portion of their 2019 Notes. Based on the daily closing prices of the Company’s stock during the quarter ended September 30, 2021, holders of the 2019 Notes are eligible to convert their 2019 Notes during the fourth quarter of 2021. Based on the terms of the 2019 Notes, when a conversion notice is received, the Company has the option to pay or deliver cash, shares of the Company’s common stock, or a combination thereof. Accordingly, the Company cannot be required to settle the 2019 Notes in cash and, therefore, the 2019 Notes are classified as long-term debt as of September 30, 2021.

2018 Convertible Debt

In March 2018, the Company issued $345.0 million aggregate principal amount of the 2018 Notes in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act. The net proceeds from the sale of the 2018 Notes were $335.0 million after deducting the initial purchasers’ discount and offering expenses. The 2018 Notes are convertible based upon an initial conversion rate of 27.5691 shares of the Company’s common stock per $1,000 principal amount of 2018 Notes (equivalent to an initial conversion price of approximately $36.27 per share). The Company used $34.2 million of the net proceeds from the 2018 Notes offering to enter into separate capped call instruments (“2018 Capped Call Transactions”) with the initial purchasers and/or their respective affiliates.

During the third quarter of 2020, the Company paid $137.2 million in cash and issued approximately 7.3 million shares of Etsy’s common stock to repurchase $301.1 million aggregate principal amount of its outstanding 2018 Notes through privately negotiated transactions. Concurrently, the Company repurchased 1.3 million shares of Etsy’s common stock for $166.2 million, in order to effectively complete the partial repurchase of 2018 Notes principal value in cash, and the conversion premium in shares. The equity component impact associated with the conversion premium on the 2018 Notes was a net increase to additional paid-in capital of $143.2 million. This transaction was accounted for as an extinguishment of debt and recorded in accordance with the applicable accounting standard in the year ended December 31, 2020. The Company recognized a non-cash loss on extinguishment of $16.9 million. This loss was calculated by comparing the carrying value of the debt component with the fair value of a similar liability that does not have an associated convertible feature immediately prior to extinguishment as well as writing off any remaining unamortized deferred debt issuance costs at the time of extinguishment.

During the nine months ended September 30, 2021, the Company paid $43.9 million in cash and issued approximately 1.0 million shares of Etsy’s common stock to settle conversion notices of $43.8 million aggregate principal amount of the outstanding 2018 Notes. The debt conversion transactions were accounted for in accordance with ASU 2020-06, which was adopted in the first quarter of 2021. See “Note 1—Basis of Presentation and Summary of Significant Accounting Policies—Recently Adopted Accounting Pronouncements” for additional information.

During any calendar quarter preceding November 1, 2022 in which the closing price of the Company’s common stock exceeds 130% of the applicable conversion price of the 2018 Notes on at least 20 of the last 30 consecutive trading days of the quarter, holders may, in the immediate quarter following, convert all or a portion of their 2018 Notes. Based on the daily closing prices of the Company’s stock during the quarter ended September 30, 2021, holders of the remaining 2018 Notes are eligible to convert their 2018 Notes during the fourth quarter of 2021. Based on the terms of the 2018 Notes, when a conversion notice is received, the Company has the option to pay or deliver cash, shares of the Company’s common stock, or a combination thereof. Accordingly, the Company cannot be required to settle the 2018 Notes in cash and, therefore, the remaining 2018 Notes are classified as long-term debt as of September 30, 2021.

The following table presents the outstanding principal amount and carrying value of the Notes as of the dates indicated (in thousands):

(1) Total interest expense for the three and nine months ended September 30, 2021 consisted of coupon interest and amortization of debt issuance costs, as there is no amortization of the debt discount in the current year due to the adoption of ASU 2020-06 as of January 1, 2021, as described in “Note 1—Basis of Presentation and Summary of Significant Accounting Policies—Recently Adopted Accounting Pronouncements.”

The estimated fair value of each of the Notes was determined through inputs that are observable in the market, and are classified as Level 2. See “Note 6—Fair Value Measurements” for more information regarding the fair value of the Notes.

The Notes are general unsecured obligations of the Company. The Notes rank senior in right of payment to all of the Company’s future indebtedness that is expressly subordinated in right of payment to the Notes; rank equal in right of payment with all of the Company’s liabilities that are not so subordinated; are effectively junior to any of the Company’s secured indebtedness; and are structurally junior to all indebtedness and liabilities (including trade payables) of the Company’s subsidiaries.

2019 Credit Agreement

On February 25, 2019, the Company entered into a $200.0 million senior secured revolving credit facility pursuant to a Credit Agreement (the “2019 Credit Agreement”) with lenders party thereto from time to time, and Citibank N.A., as administrative Agent. The 2019 Credit Agreement will mature in February 2024. The 2019 Credit Agreement includes a letter of credit sublimit of $30.0 million and a swingline loan sublimit of $10.0 million.

Borrowings under the 2019 Credit Agreement (other than swingline loans) bear interest, at the Company’s option, at (i) a base rate equal to the highest of (a) the prime rate, (b) the federal funds rate plus 0.50%, and (c) an adjusted LIBOR rate for a one-month interest period plus 1.00%, in each case plus a margin ranging from 0.25% to 0.875% or (ii) an adjusted LIBOR rate plus a margin ranging from 1.25% to 1.875%. Swingline loans under the 2019 Credit Agreement bear interest at the same base rate (plus the margin applicable to borrowings bearing interest at the base rate). These margins are determined based on the senior secured net leverage ratio (defined as secured funded debt, net of unrestricted cash up to $100 million, to EBITDA) for the 12-month period consisting of the preceding four fiscal quarter periods. The Company is also obligated to pay other customary fees for a credit facility of this size and type, including an unused commitment fee, ranging from 0.20% to 0.35% depending on the Company’s senior secured net leverage ratio, and fees associated with letters of credit.

The Company capitalized $1.4 million of debt issuance costs in connection with the 2019 Credit Agreement. Total unamortized debt issuance costs related to the 2019 Credit Agreement were $0.7 million and $0.9 million as of September 30, 2021 and December 31, 2020, respectively. Non-cash interest expense related to debt issuance costs on the 2019 Credit Agreement for both the three months ended September 30, 2021 and 2020 was $0.1 million. Non-cash interest expense related to debt issuance costs on the 2019 Credit Agreement for both the nine months ended September 30, 2021 and 2020 was $0.2 million. At September 30, 2021 and December 31, 2020, the Company did not have any borrowings under the 2019 Credit Agreement and was in compliance with all financial covenants.

Note 9—Commitments and Contingencies

In June 2021, the Company issued the 2021 Notes, see “Note 8—Debt” for more information. Additionally, in June 2021 the Company entered into a 5-year contractual commitment for cloud-based services with an aggregate future minimum payment obligation of $525.0 million, which includes escalating commitments each contract year. Commitments did not materially change during the nine months ended September 30, 2021 except for this activity.

Legal Proceedings

From time to time in the normal course of business, various other claims and litigation have been asserted or commenced against the Company. Due to uncertainties inherent in litigation and other claims, the Company can give no assurance that it will prevail in any such matters, which could subject the Company to significant liability for damages. Any claims or litigation could have an adverse effect on the Company’s results of operations, cash flows, or business and financial condition in the period the claims or litigation are resolved. Although the results of litigation and claims cannot be predicted with certainty, the Company currently believes that the final outcome of these ordinary course matters will not have a material adverse effect on its business.

Equity [Abstract]

Stockholders' Equity

Note 10—Stockholders’ Equity

In December 2020, the Board of Directors approved a stock repurchase program that enables the Company to repurchase up to $250 million of its common stock. The program does not have a time limit and may be modified, suspended, or terminated at any time by the Board of Directors. The number of shares repurchased and the timing of repurchases will depend on a number of factors, including, but not limited to, stock price, trading volume, and general market conditions, along with Etsy’s working capital requirements, general business conditions, and other factors.

Under the stock repurchase program, the Company may purchase shares of its common stock through various means, including open market transactions, privately negotiated transactions, tender offers, or any combination thereof. In addition, open market repurchases of common stock could be made pursuant to trading plans established pursuant to Rule 10b5-1 under the Securities Exchange Act of 1934, as amended, which would permit common stock to be repurchased at a time that the Company might otherwise be precluded from doing so under insider trading laws or self-imposed trading restrictions.

In June 2021 the Company repurchased approximately 1.1 million shares of its common stock for approximately $180.0 million concurrently with the issuance of the 2021 Notes, see “Note 8—Debt.” This repurchase was separate from the stock repurchase plan approved by the Board of Directors in December 2020.

The following table summarizes the Company’s cumulative share repurchase activity under the program noted above, excluding shares withheld to satisfy tax withholding obligations in connection with the vesting of employee RSUs and excluding the 1.1 million shares repurchased in June 2021 (in thousands, except share and per share amounts):

Stock-Based Compensation

Share-based Payment Arrangement [Abstract]

Stock-Based Compensation

Note 11—Stock-Based Compensation

During the three and nine months ended September 30, 2021, the Company granted stock options and RSUs, including Financial PBRSUs and TSR PBRSUs, under its 2015 Equity Incentive Plan (“2015 Plan”) and, pursuant to the evergreen increase provision of the 2015 Plan, 6,291,797 additional shares were added to the total number of shares available for issuance under the 2015 Plan effective as of January 4, 2021. At September 30, 2021, 44,040,744 shares were authorized under the 2015 Plan and 29,533,786 shares were available for future grant.

Starting in the second quarter of 2021, the Company updated certain assumptions used to determine the fair value of its stock options under the Black-Scholes option-pricing model, including the expected volatility and expected term assumptions. Given Etsy’s sufficient trading history as of the second quarter of 2021, the Company calculates expected volatility based solely on the historical volatility of Etsy’s stock price observations over a period equivalent to the expected term of the stock option grants. Prior to the second quarter of 2021, the Company estimated expected volatility by taking the average historical price volatility for Etsy and certain industry peers. Further, given that the Company has sufficient historical exercise data to provide a reasonable basis upon which to estimate the expected term of its stock options, beginning in the second quarter, the Company estimates its expected term using historical option exercise behavior and expected post-vest cancellation data, averaged with an assumption that recently granted options will be exercised ratably from vesting to the expiration of the stock option. Prior to the second quarter of 2021, the Company used the simplified method to calculate the expected term for awards issued to employees or members of the Company’s Board of Directors. These updated assumptions have been applied prospectively to option awards granted in or after the second quarter of 2021. The Company does not expect these changes to have a material impact on the Consolidated Statements of Operations.

The fair value of options granted in the periods presented below using the Black-Scholes pricing model has been based on the following assumptions:

	Three Months Ended   September 30,		Nine Months Ended   September 30,
	2021	2020	2021	2020
Volatility	56.0%	41.7%	43.4% - 56.1%	38.9% - 41.7%
Risk-free interest rate	0.9%	0.3%	0.8% - 1.1%	0.3% - 1.7%
Expected term (in years)	5.12	6.12 - 6.16	4.86 - 6.15	5.52 - 6.16

The following table summarizes the activity for the Company’s options during the nine months ended September 30, 2021 (in thousands, except share and per share amounts):

	Shares	Weighted-Average Exercise Price		Weighted-Average Remaining Contract Term (in years)	Aggregate Intrinsic Value
Outstanding at December 31, 2020	5,099,952	$	20.97	6.81	$	800,453

Total exercisable at September 30, 2021	3,813,551	15.25		5.68	734,923

The following table summarizes the weighted-average grant date fair value of options granted, intrinsic value of options exercised, and fair value of awards vested during the three and nine months ended September 30, 2021 and 2020 (in thousands, except per share amounts):

	Three Months Ended   September 30,				Nine Months Ended   September 30,
	2021		2020		2021		2020
Weighted-average grant date fair value of options granted	$	96.83	$	50.68	$	94.88	$	18.18
Intrinsic value of options exercised	29,247		42,278		92,489		94,737
Fair value of awards vested	13,561		8,855		49,296		35,262

The total unrecognized compensation expense at September 30, 2021 related to the Company’s options was $27.9 million, which will be recognized over an estimated weighted-average amortization period of 2.84 years.

Service-based RSUs and, beginning in the first quarter of 2021, Financial PBRSUs and TSR PBRSUs, are awarded at fixed dollar amounts. The target number of shares underlying the awards is determined based on Etsy’s 30-day average share price leading up to and including the grant date.

For the Financial PBRSUs, the number of RSUs received will depend on the achievement of financial metrics relative to the approved performance targets. Depending on the actual financial metrics achieved relative to the target financial metrics, throughout the defined performance period of the award, the number of PBRSUs that vest could range from 0% to 200% of the target amount, and are subject to the Compensation Committee’s approval of the level of achievement against the approved performance targets. For the TSR PBRSUs, the number of RSUs received will depend on the Company’s total shareholder return relative to that of the Nasdaq Composite Index over a three-year measurement period.

In connection with the acquisitions of Depop and Elo7 in July 2021, outstanding, unvested options held by continuing employees of each acquired entity as of the respective acquisition dates were replaced with Etsy RSU awards with the same aggregate fair value, with a total dollar value of $78.8 million, $5.6 million of which relates to pre-combination service and was included as a component of the purchase price. These RSUs generally follow the original vesting schedule of the replaced options, which provided that they will vest 25% on the first anniversary of their original vesting commencement date with the remaining 75% vesting ratably each month thereafter until the fourth anniversary of their original vesting commencement date.

The following table summarizes the activity for the Company’s unvested RSUs, which includes Financial PBRSUs and TSR PBRSUs, during the nine months ended September 30, 2021:

	Shares	Weighted-Average Grant Date Fair Value
Unvested at December 31, 2020	3,085,987	$	50.28
Granted (1)	1,984,463	207.28
Vested	(864,588)	48.06
Forfeited/Canceled	(218,795)	86.94
Unvested at September 30, 2021	3,987,067	126.90

(1)Includes RSU awards issued to Depop and Elo7 employees in connection with the acquisitions in the third quarter of 2021.

The total unrecognized compensation expense at September 30, 2021 related to the Company’s unvested RSUs, including the Financial PBRSUs and TSR PBRSUs, was $449.2 million, which will be recognized over an estimated weighted-average amortization period of 3.11 years.

In connection with the acquisition of Depop, certain Depop executives are eligible to receive deferred consideration of $44.0 million in Etsy shares over the three years following the acquisition date, subject to certain service-based vesting conditions during the vesting period. These awards will be settled by issuing Etsy shares on or shortly following the applicable vesting date, with the number of shares to be determined based on the Company’s stock price on the applicable vesting date, and will therefore be recognized as post-combination service stock-based compensation expense over a three-year vesting period, with a corresponding liability included within Other liabilities on the Company’s Consolidated Balance Sheets until the service-based vesting criteria are met and the awards are settled in Etsy shares. The unrecognized compensation expense at September 30, 2021 related to these awards was $40.8 million, which will be recognized over a remaining term of 2.78 years. These amounts are excluded from the unrecognized compensation expense associated with the Company’s unvested RSUs noted above.

Stock-based compensation expense included in the Consolidated Statements of Operations for the periods presented below is as follows (in thousands):

	Three Months Ended   September 30,				Nine Months Ended   September 30,

Subsequent Event

Note 12—Subsequent Event

In October 2021, the Company entered into a First Amendment to Lease (the "First Amendment") related to the Company's corporate headquarters located at 117 Adams Street and 55 Prospect Street, Brooklyn, NY. The First Amendment extends the expiration of the term of the current lease from July 31, 2026 to July 31, 2039 with an incremental future minimum payment obligation of approximately $163 million, $38 million of which relates to payments under the Company’s operating lease commitments, and $125 million of which relates to payments under the Company’s finance lease commitments. This aggregate increase to the Company’s minimum payment obligations includes a tenant allowance, a portion of which becomes available beginning in April 2022, rent concessions that become available in 2026, and escalating commitments each contract year between 2028 and 2038. The First Amendment is expected to result in increases to the Company’s right of use assets and lease liabilities related to the Company's operating and finance leases, which will result in the following changes within the Company's Consolidated Balance Sheets (in thousands):

Property, plant and equipment, net	$	66,413

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Consolidation

Basis of ConsolidationThe consolidated financial statements include the accounts of Etsy and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. On July 2, 2021, Etsy acquired all the outstanding shares of Elo7 Serviços de Informática S.A. (“Elo7”) by means of a merger, and on July 12, 2021 Etsy acquired all of the issued share capital of Depop Limited (“Depop”) pursuant to a share purchase. The financial results of Elo7 and Depop have been included in Etsy’s Consolidated Financial Statements from the respective dates of acquisition.

Basis of Presentation

Basis of Presentation

The accompanying unaudited interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and pursuant to the applicable rules and regulations of the Securities and Exchange Commission (“SEC”). The Company has condensed or omitted certain information and notes normally included in complete annual financial statements prepared in accordance with GAAP. These unaudited interim consolidated financial statements should therefore be read in conjunction with the audited consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K filed with the SEC on February 26, 2021 (the “Annual Report”). In the opinion of management, all material adjustments, which are of a normal and recurring nature, necessary for a fair presentation of the results for the periods presented have been reflected in the consolidated financial statements. The results of operations of any interim period are not necessarily indicative of the results of operations for the full annual period or any future period due to seasonal and other factors.

Use of Estimates

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires the Company to make estimates and judgments that affect the amounts reported and disclosed in the consolidated financial statements and accompanying notes. Actual results could differ from these estimates and judgments. The accounting estimates that require management’s most subjective judgments include: stock-based compensation; income taxes, including the estimate of the annual effective tax rate at interim periods and evaluation of uncertain tax positions; purchase price allocations for business combinations and valuation of acquired intangible assets, developed technology, and goodwill. As of September 30, 2021, the effects of the ongoing COVID-19 pandemic and progress towards its abatement on the Company’s business, results of operations, and financial condition continue to evolve. As a result, many of the Company’s estimates and judgments required increased judgment and carry a higher degree of variability and volatility. As additional information becomes available, the Company’s estimates may change materially in future periods.

Stock-Based Compensation

Stock-Based Compensation

Service based stock options, service based restricted stock units (“RSUs”), and performance based restricted stock units (“PBRSUs”) are awarded to employees, officers, and members of the Company’s Board of Directors. The PBRSUs include financial performance based restricted stock units (“Financial PBRSUs”) and total shareholder return performance based restricted stock units (“TSR PBRSUs”), both of which have performance and service vesting requirements. The Company recognizes forfeitures as they occur.

The Company calculates the fair value of stock options on the date of grant using the Black-Scholes option-pricing model. The fair value of RSUs is measured using the closing price of the Company’s common stock on Nasdaq on the grant date. Additionally, the fair value of the Financial PBRSUs is determined using a probability assessment and the fair value of the TSR PBRSUs with market conditions are determined using a Monte-Carlo simulation model.

For PBRSUs, the Company recognizes stock-based compensation expenses on a straight-line basis over the longer of the derived, explicit, or implicit service period. As of interim and annual reporting periods, the Financial PBRSUs stock-based compensation expense is adjusted based on expected achievement of performance targets, while TSR PBRSUs stock-based compensation expense is not adjusted.

Recently Issued Accounting Pronouncements and Recently Adopted Accounting Pronouncements

Recently Issued Accounting Pronouncements

In October 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2021-08—Business Combinations (Topic 805)—Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires contract assets and contract liabilities acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with Accounting Standards Codification Topic 606—Revenue from Contracts with Customers (“ASC 606”). Under current GAAP, an acquirer generally recognizes assets acquired and liabilities assumed in a business combination, including contract assets and contract liabilities arising from revenue contracts with customers, at fair value on the acquisition date. This ASU will result in the acquirer recording acquired contract assets and liabilities on the same basis that would have been recorded by the acquiree before the acquisition under ASC 606. The amendments in this ASU do not affect the accounting for other assets or liabilities that may arise from revenue contracts with customers in accordance with ASC 606, such as refund liabilities, or in a business combination, such as customer-related intangible assets and contract-based intangible assets. The new guidance is effective for annual and interim periods beginning after December 15, 2022. Early adoption is permitted, including in interim periods, for any financial statements that have not yet been issued. This update should be applied prospectively to business combinations occurring on or after the effective date of the amendments. The Company is currently evaluating the impact that this new guidance may have on its consolidated financial statements.

Recently Adopted Accounting Pronouncements

In August 2020, the FASB issued ASU 2020-06—Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity's Own Equity (Subtopic 815-40)—Accounting For Convertible Instruments and Contracts in an Entity's Own Equity (“ASU 2020-06”). ASU 2020-06 simplifies accounting for convertible instruments by removing major separation models previously required under GAAP. Consequently, more convertible debt instruments will be reported as a single liability instrument with no separate accounting for embedded conversion features through equity. Without an initial allocation of proceeds to the conversion option, the debt will likely have a lower discount, thereby resulting in less non-cash interest expense through accretion. ASU 2020-06 removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception, which will permit more equity contracts to qualify for it. ASU 2020-06 also simplifies the diluted net income per share calculation in certain areas. The new guidance is effective for annual and interim periods beginning after December 15, 2021, and early adoption is permitted for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. This update permits the use of either the modified retrospective or fully retrospective method of transition.

The Company early adopted this standard, effective as of January 1, 2021, on a modified retrospective basis. The adoption of this standard had a material effect on the Company’s consolidated financial statements. The most significant effects related to the 0.125% Convertible Senior Notes due 2027 (the “2020 Notes”), 0.125% Convertible Senior Notes due 2026 (the “2019 Notes”), and 0% Convertible Senior Notes due 2023 (the “2018 Notes” and together with the 0.25% Convertible Senior Notes due 2028 (the “2021 Notes”), the 2020 Notes, and the 2019 Notes, the “Notes”), and included derecognition of the unamortized debt discount, which was recorded as a direct deduction from the Notes, resulting in an increase in long-term debt, net of approximately $264 million; derecognition of the equity component, which represents the value of the conversion option on the issuance date of the Notes outstanding, resulting in a reduction in additional paid-in capital of approximately $229 million, net of taxes; derecognition of deferred tax liabilities of approximately $63 million; and reversal of the cumulative debt discount recognized as interest expense in the Company’s Consolidated Statements of Operations since the date of issuance of each of the Notes to the period ending December 31, 2020, resulting in a decrease of accumulated deficit of approximately $28 million, net of taxes. The Company also had a reduction in interest expense due to the adoption of ASU 2020-06 as the debt discount has been derecognized and, effective January 1, 2021, there is no amortization of the debt discount. The Company did not incur any impact to liquidity or cash flows. When calculating net income per share of common stock attributable to common stockholders, the Company uses the if-converted method as required under ASU 2020-06 to determine the dilutive effect of the Notes.
