FORWARD-LOOKING STATEMENTS

This Annual Report on Form 10-K contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, including statements regarding our future results of operations and financial position, business strategy and plans and our objectives for future operations. The words "may," "will," "should," "could," "expect," "anticipate," "believe," "estimate," "intend," "continue" and other similar expressions are intended to identify forward-looking statements. We have based these forward-looking statements largely on current expectations and projections about future events and financial trends that we believe may affect our financial condition, results of operations, business strategy, short-term and long-term business operations and objectives, and financial needs. These forward-looking statements involve risks and uncertainties that could cause our actual results to differ materially from those expressed or implied in our forward-looking statements. Such risks and uncertainties include, but are not limited to, effects of COVID-19 or other pandemics or disease outbreaks on our business; our ability to execute, and achieve the expected benefits of our go-forward strategy; execution of our business and marketing strategies; volatility in our operating results; challenges arising from our international operations, including fluctuations in currency exchange rates, legal and regulatory developments and any potential adverse impact from the United Kingdom's exit from the European Union; global economic uncertainty; retaining and adding high quality merchants; retaining existing customers and adding new customers; competing successfully in our industry; providing a strong mobile experience for our customers; managing refund risks; retaining and attracting members of our executive team and other qualified personnel; customer and merchant fraud; payment-related risks; our reliance on email, internet search engines and mobile application marketplaces to drive traffic to our marketplace; cybersecurity breaches; maintaining and improving our information technology infrastructure; reliance on cloud-based computing platforms; completing and realizing the anticipated benefits from acquisitions, dispositions, joint ventures and strategic investments; lack of control over minority investments; managing inventory and order fulfillment risks; claims related to product and service offerings; protecting our intellectual property; maintaining a strong brand; the impact of future and pending litigation; compliance with domestic and foreign laws and regulations, including the CARD Act, GDPR and regulation of the Internet and e-commerce; classification of our independent contractors or employees; exposure to greater than anticipated tax liabilities; adoption of tax legislation; our ability to raise capital if necessary; risks related to our access to capital and outstanding indebtedness, including our convertible senior notes; our common stock, including volatility in our stock price; our ability to realize the anticipated benefits from the hedge and warrant transactions; and those risks and other factors discussed in Part I, Item 1A. Risk Factors of this Annual Report on Form 10-K, as well as in our consolidated financial statements, related notes, and the other financial information appearing elsewhere in this report and our other filings with the Securities and Exchange Commission (the "SEC"). Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. We do not intend, and undertake no obligation, to update any of our forward-looking statements after the date of this report to reflect actual results or future events or circumstances. Given these risks and uncertainties, readers are cautioned not to place undue reliance on such forward-looking statements.

As used herein, "Groupon," "the Company," "we," "our," "us" and similar terms include Groupon, Inc. and its subsidiaries, unless the context indicates otherwise.

ITEM 1. BUSINESS

Groupon is a global scaled two-sided marketplace that connects consumers to merchants. Consumers access our marketplace through our mobile applications and our websites, primarily localized groupon.com sites in many countries. We operate in two segments, North America and International, and in three categories, Local, Goods and Travel. Our mission is to be the destination where consumers discover fun things to do and local businesses thrive. For our customers, this means giving them an amazing selection of experiences at great values. For our merchants, this means making it easy for them to partner with Groupon and reach millions of consumers around the world.

Currently, we generate product and service revenue from the following business operations.

Service Revenue from Local, Travel, and Goods Categories: Service revenue primarily represents the net commissions earned from selling goods or services on behalf of third-party merchants. Service revenue is reported on a net basis as the purchase price collected from the customer less the portion of the purchase price that is payable to the third-party merchant. We also earn commissions when customers make purchases with retailers using digital coupons accessed through our websites and mobile applications.

Product Revenue from Goods Category: We generate product revenue from our sales of first-party Goods inventory, which are direct sales of merchandise inventory. For product revenue transactions, we are the primary party responsible for providing the good to the customer, we have inventory risk and we have discretion in establishing prices. As such, product revenue is reported on a gross basis as the purchase price received from the customer. Product revenue, including associated shipping revenue, is recognized when title passes to the customer upon delivery of the product. We have transitioned to a third-party marketplace in North America as of the end of 2020 and will begin to transition to a third-party marketplace in International in the second quarter 2021. Following the International transition, we expect our Goods category to primarily generate revenue on a net basis within service revenue.

GROUPON, the GROUPON logo and other GROUPON-formative marks are trademarks of Groupon, Inc. in the United States or other countries. This Annual Report on Form 10-K also includes other trademarks of Groupon and trademarks of other persons.

Our Strategy

In the third quarter 2020, we shifted our strategy and plan to prioritize expanding our Local inventory and modernizing our marketplace by improving the merchant and customer experiences. While both of these are important to building a successful marketplace, we believe the most critical of these is expanding Local inventory.

Our Categories

Local. Our Local category includes offerings from local and national merchants, and other revenue sources that are primarily generated through our relationships with local and national merchants, including advertising revenue. Our offerings comprise multiple subcategories of local experiences, including: things to do; beauty and wellness; and dining. In addition to local and national offerings, we give consumers the ability to access digital coupons from thousands of retailers through our coupons offering.

Goods. In our Goods category, we earn product revenue from transactions in which we sell merchandise inventory directly to customers, as well as service revenue from transactions in which third-party merchants sell products to customers through our marketplaces. When our transition to a third-party Goods marketplace is complete, we will primarily recognize Goods transaction revenue on a net basis within service revenue. Our Goods category currently offers merchandise across multiple product lines, including electronics, sporting goods, jewelry, toys, household items and apparel.

Travel. Through our Travel category, we feature travel offers at both discounted and market rates, including hotels, airfare and package deals covering both domestic and international travel. For many of our travel offerings, the customer must contact the merchant directly to make a travel reservation after purchasing a travel voucher from us. However, for some of our hotel offerings, customers make room reservations directly through our websites.

Distribution

Our customers access our online local commerce marketplaces through our mobile applications and our websites, which primarily consist of localized groupon.com sites in many countries. Our applications and mobile websites enable consumers to browse, purchase, manage and redeem deals on their mobile devices. For the year ended December 31, 2020, over 75% of our global transactions were completed on mobile devices.

We use a variety of marketing channels to direct customers to the offerings available through these marketplaces, as described in the Marketing section below.

Marketing

We primarily use marketing to acquire and retain customers and promote awareness of our marketplaces. In light of the impact of COVID-19 on our business in 2020, we significantly reduced marketing expense due to lower consumer demand and by shortening payback thresholds and delaying brand marketing investments. We would expect our marketing spend to increase as consumer demand recovers.

We use a variety of marketing channels to make customers aware of our offerings, including search engines, email and push notifications, affiliate channels, social and display advertising and offline marketing.

Search engines. Customers can access our offerings indirectly through third-party search engines. We use search engine optimization ("SEO") and search engine marketing ("SEM") to increase the visibility of our offerings in web search results.

Email and push notifications. We communicate offerings through email and by push notifications to our customers based on their locations and personal preferences. A customer who interacts with an email or push notification is directed to our website or mobile application to learn more about the deal and to make a purchase.

Affiliate channels. We have an affiliate program that uses third parties to promote our offerings online. Affiliates earn commissions when customers access our offerings through links on their websites and make purchases on our platform. We expect to continue to leverage affiliate relationships to extend our deals to a broad base of potential customers.

Social and display. We publish offerings through various social networks and adapt our notifications to the particular format of each of these social networking platforms. Our websites and mobile applications enable consumers to share our offerings with their personal social networks. We also promote our offerings using display advertising on websites.

Television and other offline. We use offline marketing such as television advertising, and to a lesser extent, print and radio advertising, to help build awareness of our offerings and brand.

Our marketing activities also include elements that are not presented as Marketing on our consolidated statements of operations, such as order discounts and free shipping on qualifying merchandise sales.

Human Capital Management

As of December 31, 2020, we had employees consisting of the following:


	Sales	Corporate, Operational and Customer Support	Total Employees
North America	550	774	1,324
International	726	2,109	2,835
Total	1,276	2,883	4,159

Our sales force consists of merchant sales representatives and sales support staff who acquire and build merchant relationships and provide ongoing consultative expertise. Other key operational functions include engineering, product, marketing, and editorial.

We believe attracting and retaining global talent is key to our success. Our Chief People Officer, together with our Chief Executive Officer and Chief Administrative Officer, are responsible for developing and executing our human capital strategy, with oversight of the Board and Board committees. This includes the recruitment, development, and retention of talent to support our operations and execute our strategy and the design of our employee compensation and benefit programs.

Key areas of our focus include:

Inclusion and Diversity. Inclusion and diversity is important to all aspects of our business, and particularly vital to attracting, developing and retaining employees from underrepresented groups. We believe that by building a global team of employees who have diverse experiences, backgrounds, skills and perspectives, we will be able to better support our employees, merchants and customers. We have established multiple internal diversity and inclusion resources that allow employees to engage on important issues. Some of these resources include business resource groups and resource action groups (Listen, Learn, Mobilize, and Support) that are focused on the Black Lives Matters movement. In addition to these resources, we invest in our mentoring and leadership programs as well as other events that are specifically focused on nurturing the professional development of our diverse employees, showcasing growth opportunities within Groupon, and providing them with unique tools and experiences they need to thrive at Groupon.

Workplace Culture and Values. To support talent development, we offer training and development programs supporting our ethics, workplace culture and managers. For example, we require our employees to complete unconscious bias training and Code of Conduct training. In addition, all managers must complete Respect In the Workplace Training. We also offer various other training programs to employees, such as, Change & Resilience, Managing Through Change, FS90 (leader habits and manager expectations for new leaders) and Authentic Allyship Workshops. We also encourage internal referrals and postings for open roles and partner with organizations in order to proactively recruit more candidates from diverse backgrounds.

Social Responsibility. Social responsibility is important at Groupon, and we empower our employees to volunteer and participate in the communities in which we operate and live. We believe thriving local communities are good for everyone. Further, our efforts in this area support the success of our core Local business. We provide numerous opportunities for our employees to volunteer with causes they care about throughout the year and support local communities through our platform and community development efforts.

In 2020, our business was significantly impacted by COVID-19. We implemented changes in our workforce and how we work in response to the pandemic. For example, we instituted a remote work plan and most of our employees have been working remotely since early 2020. We continue to evaluate our return to office plans, with the health and safety of our employees being a primary consideration. In addition, in response to the COVID-19 pandemic, in 2020, our Board approved a multi-phase restructuring plan that includes the termination and furlough of employees. See Item 8, Note 16, Restructuring and Related Charges, for additional information.

Technology

Our websites are hosted at two U.S. data centers in California and at an international data center in Ireland. Our data centers host our public-facing websites and applications, as well as our back-end business intelligence systems. We employ security practices to protect and maintain the systems located at our data centers. We are migrating our public-facing websites and applications and our back-end business intelligence systems to the cloud. We have invested in intrusion and anomaly detection tools to try to recognize intrusions to our websites. We engage independent third-party Internet security firms to regularly test the security of our websites and identify vulnerabilities. In financial transactions with customers conducted on our websites and mobile applications, we use data encryption protocols to secure information while in transit. See Risk Factors for additional information relating to potential cyber threats.

Competition

Our customers and merchants are at the center of our two-sided marketplace. The quality and stability of both our customers and merchants are key to our business model. We face competition on both sides of our marketplace.

We compete with other marketplaces, and some of our competitors have longer operating histories, significantly greater financial, technical, marketing and other resources. In addition, we compete with companies who address only specific verticals in the local experiences market, and in some categories, such as Goods and Travel, companies who have greater scale and larger customer bases than we do. These factors may allow our competitors to benefit from their existing customer base with lower acquisition costs or to respond more quickly than we can to new or emerging technologies and changes in customer trends. These competitors may engage in more extensive research and development efforts, undertake more far-reaching marketing campaigns and adopt more aggressive pricing policies, which may allow them to build a larger subscriber base or to monetize that subscriber base more effectively than we do.

We also compete with companies that can offer alternative services for our merchants. There are companies that offer other types of advertising and promotional services to local businesses. Our merchants could choose to leverage these other platforms to attract customers to their businesses. We believe we can compete due to the access we provide our merchants to our large customer base, our trusted brand, and the investments we are making in self-service tools that will allow merchants to manage demand more effectively and better attract and retain customers.

Seasonality

Historically, we experienced seasonal buying patterns mirroring that of the larger consumer retail and e-commerce markets, where demand increases during the fourth quarter holiday season. That seasonal pattern was less pronounced in 2020 due to the impacts of COVID-19 on our business.

Regulation

We are subject to a number of foreign and domestic laws and regulations that affect companies conducting business on the Internet. Additionally, those laws and regulations may be interpreted differently across domestic and foreign jurisdictions. As a company in a relatively new and rapidly innovating industry, we are exposed to the risk that many of those laws may evolve or be interpreted by regulators or in the courts in ways that could materially affect our business. Those laws and regulations may involve taxation, unclaimed property, intellectual property, product liability, travel, distribution, electronic contracts and other communications, competition, consumer protection, the provision of various online payment services, employee, merchant and customer privacy and data security or other areas.

The Credit Card Accountability Responsibility and Disclosure Act of 2009 (the "CARD Act"), as well as the laws of most states, contain provisions governing gift cards, gift certificates, stored value or pre-paid cards or coupons ("gift cards"). Groupon vouchers may be included within the definition of "gift cards" under many laws. In addition, certain foreign jurisdictions have laws that govern disclosure and certain product terms and conditions, including restrictions on expiration dates and fees, that may apply to Groupon vouchers. There are also a number of legislative proposals pending before the U.S. Congress, various state legislative bodies and foreign governments that could affect us, and our global operations may be constrained by regulatory regimes and laws in Europe and other jurisdictions outside the United States that may be more restrictive and adversely impact our business.

Various U.S. laws and regulations, such as the Bank Secrecy Act of 1970 (the "Bank Secrecy Act"), the Dodd-Frank Wall Street Reform and Consumer Protection Act, the USA PATRIOT Act and the CARD Act impose certain anti-money laundering requirements on companies that are financial institutions or that provide financial products and services. Those laws and regulations broadly define financial institutions to include money services businesses such as money transmitters, check cashers and sellers or issuers of stored value. Requirements imposed on financial institutions under those laws include customer identification and verification programs, record retention policies and procedures and transaction reporting. We do not believe that we are a financial institution subject to those laws and regulations.

We are subject to a variety of federal, state and international laws and regulations governing consumer data. The General Data Protection Regulation ("GDPR"), which was adopted by the European Union and became effective in May 2018, and the California Consumer Privacy Act (“CCPA”) which became effective January 1, 2020, require companies to satisfy specific requirements regarding the handling of personal and sensitive data, including its collection, use, protection and the ability of persons whose data is stored to, among other things, access and/or delete such data about themselves. Our ongoing efforts to comply with the GDPR, CCPA and other relevant privacy and data protection laws and regulations, have required updates to certain business practices and systems. Non-

compliance with any privacy and data protection laws and regulations could result in significant monetary fines. For instance, non-compliance with the GDPR could result in proceedings against us by governmental entities or others and fines up to the greater of €20 million or 4% of annual global revenue. We continue to monitor developments in laws and regulations relating to privacy and consumer data, and we expect these evolving laws and regulations will continue to impact our business in the future.

Intellectual Property

We protect our intellectual property rights by relying on federal, state and common law rights, as well as contractual restrictions. We control access to our proprietary technology by entering into confidentiality and invention assignment agreements with our employees and contractors, and confidentiality agreements with third parties.

In addition to those contractual arrangements, we also rely on a combination of trade secrets, copyrights, trademarks, service marks, trade dress, domain names and patents to protect our intellectual property. Groupon and its related entities own a number of trademarks and service marks registered or pending in the United States and internationally. In addition, we own a number of issued patents and pending patent applications in the United States and internationally and own and have applied for copyright registrations in the United States.

Circumstances outside our control could pose a threat to our intellectual property rights and the efforts we have taken to protect our proprietary rights may not be sufficient or effective or deter independent development of equivalent or superior intellectual property rights by others. Any significant impairment of our intellectual property rights could harm our business or our ability to compete. Also, protecting our intellectual property rights is costly and time-consuming. Any unauthorized disclosure or use of our intellectual property could make it more expensive to do business and harm our operating results.

Companies in the Internet, technology and other industries as well as non-practicing entities may own large numbers of patents, copyrights and trademarks or other intellectual property rights and may request license agreements, threaten litigation or file suit against us based on allegations of infringement or other violations of intellectual property rights. We are currently subject to, and expect to face in the future, lawsuits and allegations that we have infringed the intellectual property rights of third parties. As our business grows, we will likely face more claims of infringement, and may experience an adverse result which could impact our business and/or our operating results.

We have received in the past, and we anticipate we will receive in the future, communications alleging that items offered or sold through our website infringe third-party copyrights, trademarks, patents and trade names or other intellectual property rights or that we have otherwise infringed third parties’ past, current or future intellectual property rights. We may be unable to prevent third parties from offering and selling unlawful or infringing goods or goods of disputed authenticity, and we may be subject to allegations of civil or criminal liability for unlawful activities carried out by third parties through our website. We may implement measures in an effort to protect against these potential liabilities that could require us to spend substantial resources and/or to reduce revenue by discontinuing certain service offerings. Any costs incurred as a result of liability or asserted liability relating to the sale of unlawful goods or the unlawful sale of goods could harm our business.

Financial Statements and Supplementary Data of this Annual Report on Form 10-K.

Summary Risk Factors

The following is a summary of some of the risks and uncertainties that could materially adversely affect our business, prospects, financial condition, operating results and the trading price of our common stock. You should read this summary together with the more detailed description of each risk factor contained below.

Risks Related to Our Business, Operations and Strategy

•The COVID-19 pandemic has, and is expected to continue to, materially affect our business, financial condition and results of operations, and any future outbreaks of contagious diseases and other adverse public health developments could materially affect our business.

•Our strategy may be unsuccessful and may expose us to additional risks. If our strategy does not achieve its expected benefits, there could be negative impacts to our business, financial condition and results of operations.

•Our operating results may vary significantly from quarter to quarter.

•Our international operations are subject to varied and evolving commercial, employment and regulatory challenges, and our inability to adapt to the diverse and changing landscapes of our international markets may adversely affect our business.

•Our future success depends upon our ability to attract and retain high quality merchants and third-party business partners.

•If we fail to retain our existing customers or acquire new customers, our operating results and business will be harmed.

•We operate in a highly competitive industry with relatively low barriers to entry and must compete successfully in order to grow our business.

•Our success is dependent upon our ability to provide a superior mobile experience for our customers and our customers' continued ability to access our offerings through mobile devices.

•An increase in our refund rates or estimated liabilities with respect to unredeemed vouchers could adversely affect our financial results.

•The loss of key members of our management team, or our failure to attract and retain other highly qualified personnel in the future could harm our business.

•Failure to deal effectively with fraudulent transactions and customer disputes would increase our loss rate and harm our business.

•We are subject to payments-related risks.

Risks Related to Technology and Cybersecurity

•We rely on email, Internet search engines and mobile applications to drive traffic to our marketplace.

•We may be subject to breaches of our information technology systems, which could harm our relationships with our customers, merchants and third-party business partners, subject us to negative publicity and litigation, and cause substantial harm to our business or brand.

•Our business depends on our ability to maintain and improve the technology infrastructure necessary to send our emails and operate our websites, mobile applications and transaction processing systems, and any significant disruption in service on our email network infrastructure, websites, mobile applications or transaction processing systems could result in a loss of customers or merchants.

•As we increase our reliance on cloud-based platforms to operate and deliver our products and services, any disruption or interference with these platforms could adversely affect our financial condition and results of operations.

Risks Related to Transactions and Investments

•Acquisitions, dispositions, joint ventures and strategic investments could result in operating difficulties, dilution and other consequences.

•We do not have the ability to exert control over our minority investments, and therefore we are dependent on others in order to realize their potential benefits.

Risks Related to Our Brand and Intellectual Property

•We allow third parties to sell products via our site and services and purchase and sell some products from indirect suppliers, which increase our risk of litigation and other losses.

•We may be subject to substantial liability claims and damage to our brand and reputation if people or property are harmed by the products or services offered through our marketplace.

•We may not be able to adequately protect our intellectual property rights or may be accused of infringing intellectual property rights of third parties.

•Our business depends on a strong brand, and if we are not able to maintain and enhance our brand, our ability to expand our base of customers and merchants could be impaired and our business and operating results could be harmed.

Risks Related to Legal, Regulatory, Privacy and Tax Matters

•We are involved in pending litigation and other claims and an adverse resolution of such matters may adversely affect our business, financial condition, results of operations and cash flows.

•The application of certain laws and regulations, including, among other laws, the CARD Act and similar state and foreign laws, may harm our business and results of operations.

•If we are required to materially increase the liability recorded in our financial statements with respect to unredeemed vouchers our results of operations could be materially and adversely affected.

•Government regulation of the Internet and e-commerce is evolving, and unfavorable changes or failure by us to comply with these regulations could substantially harm our business and results of operations.

•Failure to comply with federal, state and international privacy laws and regulations, or the expansion of current or the enactment of new privacy laws or regulations, could adversely affect our business.

•Misclassification or reclassification of our independent contractors or employees could increase our costs and adversely impact our business.

•We may have exposure to greater than anticipated tax liabilities.

•The adoption of tax reform policies, including the enactment of legislation or regulations implementing changes in the tax treatment of companies engaged in Internet commerce or the U.S. taxation of international business activities could materially affect our financial position and results of operations.

•Federal laws and regulations, such as the Bank Secrecy Act and the USA PATRIOT Act and similar foreign laws, could be expanded to include Groupon vouchers or other offerings.

•State and foreign laws regulating money transmission could be expanded to include Groupon vouchers or other Groupon products or services.

Risks Related to Our Capital Structure

•Our access to capital and ability to raise capital in the future may be limited, which could prevent us from growing, and our existing credit agreement could restrict our business activities.

•We may not have the ability to use cash to settle the principal amount of our 3.25% convertible notes due 2022 (the "Notes") upon conversion or to repurchase the Notes upon a fundamental change, which could result in dilution and could adversely affect our financial condition.

•The terms of the Notes could delay or prevent an attempt to take over our Company.

Risks Related to Ownership of Our Common Stock

•The trading price of our common stock is highly volatile.

•If securities or industry analysts do not publish research or reports about our business, or publish inaccurate or unfavorable research reports about our business, our share price and trading volume could decline.

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

•Provisions in our charter documents and under Delaware law could discourage a takeover that stockholders may consider favorable.

•The convertible note hedge and warrant transactions may affect the value of our common stock.

Risks Related to Our Business, Operations and Strategy

COVID-19 pandemic has, and is expected to continue to, materially affect our business, financial condition and results of operations, and any future outbreaks of contagious diseases and other adverse public health developments could materially affect our business.

The COVID-19 pandemic has had a material impact on our business and results of operations. COVID-19 has resulted in significant governmental measures being implemented to control the spread of the virus, including quarantines, travel restrictions, business shutdowns and restrictions on the movement and gathering of people in the United States and abroad. Our business has been adversely affected in jurisdictions that have imposed mandatory closures of our merchants, sought voluntary closures or imposed restrictions on operations of our merchants and activities of consumers, and the continued implementation of such measures may further adversely affect our business. Even if such measures are not implemented, the perceived risk of infection or significant health risk may adversely affect our business. Further, the timing of global vaccination distribution and administration and the long-term effectiveness of any vaccines against COVID-19 and any variants is not certain. The outbreak and the preventive or protective actions that governments or our merchants and consumers have taken and may take in the future in response to COVID-19 has resulted, and may continue to result, in a period of business disruption, reduced voucher and travel sales and increased refunds. Further, any future outbreaks of contagious diseases and other adverse public health developments could materially affect our business.

Such risks could also adversely affect consumers’ financial condition, resulting in reduced spending on our offerings and increased refunds, even after restrictions to everyday activities are lifted. COVID-19 may also adversely affect our ability to implement our strategy to focus on growing our local marketplace.

The cost-saving actions, remote working environment, and other actions we have taken to attempt to address and mitigate the effects of COVID-19 on our business may lead to disruptions in our business, inability to grow and evolve our brand, reduced employee morale, engagement and productivity, increased attrition, problems retaining existing and recruiting future employees, limited resources to complete projects efficiently, and increased workload for employees all of which could negatively impact our business, results of operations, financial condition and create risks to the effectiveness of our internal controls. Such disruption also could negatively impact our ability to realize the full benefits of our strategy.

These and other potential impacts of COVID-19 have and are expected to continue to adversely affect our business, financial condition and results of operations. The ultimate extent of the impact of COVID-19 (or any epidemic, pandemic or other health crisis) will depend on future developments, which are highly uncertain and cannot be predicted, including new information that may emerge concerning the severity of COVID-19, emerging virus variants and the actions taken to contain COVID-19 and address its impact.

The potential effects of COVID-19 also could intensify or otherwise affect many of our other risk factors that are included in this Annual Report, including, but not limited to, risks related to the execution of our strategy, customer and merchant acquisition and retention, macroeconomic factors beyond our control, risks of doing business outside of the United States and risks related to our indebtedness. Because the COVID-19 situation is unprecedented and continuously evolving, the other potential impacts to our risk factors that are further described in this Annual Report are uncertain.

Furthermore, because the COVID-19 pandemic did not impact our results until late in the first quarter of 2020, such impact may not be directly comparable to any historical period and is not necessarily indicative of any future impact that the COVID-19 pandemic may have on our results for subsequent periods. See Item 8, Note 3, COVID-19 Pandemic, for more information.

Our strategy may be unsuccessful and may expose us to additional risks. If our strategy does not achieve its expected benefits, there could be negative impacts to our business, financial condition and results of operations.

We are implementing a strategy to grow our local experiences marketplace and return the Company to growth. We intend to execute our strategy by focusing on our priorities: (i) expanding inventory and (ii) modernizing our marketplace by improving the merchant and customer experiences.

There are no assurances that our actions will be successful in building out a local experiences marketplace and returning the Company to growth. Our efforts to execute our strategy may prove more difficult than we currently anticipate. Further, we may not succeed in realizing the benefits of these efforts on our anticipated timeline or at all.

In addition, as we implement our strategy, COVID-19 related volatility and its impact on our merchants and customers may make it more difficult to quickly test, learn and scale different initiatives relating to expanding inventory or improving the merchant and customer experiences. Further, the data we obtain during the period impacted by COVID-19 may not ultimately be indicative of merchant and customer preferences or behavior in the future. Even if fully implemented, our strategy may not result in a return to growth or the other anticipated benefits to our business, financial condition and results of operations. If we are unable to effectively execute our strategy and realize its anticipated benefits, it could negatively impact our business, financial condition and results of operations.

Our operating results may vary significantly from quarter to quarter.

Our operating results may vary significantly from quarter to quarter due to the rapidly evolving nature of our business and other reasons, including seasonality. We believe that our ability to achieve and maintain revenue growth and profitability will depend, among other factors, on our ability to:

•recover from the impact of COVID-19;

•acquire new customers, retain existing customers and increase customer purchase frequency;

•attract and retain high-quality merchants;

•effectively address and respond to challenges in international markets;

•increase the variety, quality, density and relevance of supply, including through third party business partners and technology integrations;

•deliver a modern customer and merchant experience on our website and mobile applications;

•successfully transition our Goods category to a third party marketplace model, including implementing necessary technology and operational changes related to the transition;

•increase booking capabilities;

•increase the awareness of, and evolve, our brand to a local experiences marketplace;

•continue to reduce costs and improve SG&A leverage, including through the execution of our restructuring plan;

•successfully achieve the anticipated benefits of business combinations or acquisitions, strategic investments, divestitures and restructuring activities;

•provide a superior customer service experience for our customers;

•avoid interruptions to our services, including as a result of attempted or successful cybersecurity attacks or breaches;

•respond to continuous changes in consumer and merchant use of technology;

•optimize and diversify our traffic channels;

•react to challenges from existing and new competitors;

•respond to seasonal changes in supply and demand; and

•address challenges from existing and new laws and regulations.

In addition, our margins and profitability may depend on our inventory mix, geographic revenue mix, discount rates mix, transition of the Goods category to a third-party marketplace model and merchant and third-party business partner pricing terms. Accordingly, our operating results and profitability may vary significantly from quarter to quarter.

Our international operations are subject to varied and evolving commercial, employment and regulatory challenges, and our inability to adapt to the diverse and changing landscapes of our international markets may adversely affect our business.

Our international operations require management attention and resources and also require us to localize our services to conform to a wide variety of local cultures, business practices, laws and policies. Our international operations are subject to numerous risks, including the following:

•our ability to maintain merchant and customer satisfaction such that our marketplace will continue to attract high quality merchants;

•our ability to successfully respond to macroeconomic challenges, including the impact of COVID-19 and the ability to optimize our supply to take into account consumer preferences at a particular point in time;

•political, economic and civil instability and uncertainty (including acts of terrorism, civil unrest, labor unrest, violence and outbreaks of war and pandemics or other disease outbreaks);

•currency exchange rate fluctuations;

•strong local competitors, who may better understand the local market and/or have greater resources in the local market;

•different regulatory or other legal requirements (including potential fines and penalties that may be imposed for failure to comply with those requirements), such as regulation of gift cards and coupon terms, Internet services, professional selling, distance selling, bulk emailing, privacy and data protection (including GDPR), cybersecurity, business licenses and certifications, taxation (including the European Union's voucher directive, digital service tax and similar regulations), consumer protection laws including those restricting the types of services we may offer (e.g., medical-related services), banking and money transmitting, that may limit or prevent the offering of our services in some jurisdictions, cause unanticipated compliance expenses or limit our ability to enforce contractual obligations;

•our ability to use a common technology platform in our North America and International segments to operate our business without significant business interruptions or delays;

•difficulties in integrating with local payment providers, including banks, credit and debit card networks and electronic funds transfer systems;

•the ability to quickly and effectively consult and negotiate with our international workers' councils and trade unions on various matters including restructuring actions, strategic decisions and other business critical matters, which could result in the delay of executing key actions or product delivery and increase costs;

•the local legal restrictions relating to employment terminations and staffing due to COVID-19 which impacts our ability to complete our restructuring actions;

•difficulty in staffing, developing and managing foreign operations, including through centralized shared service centers, as a result of distance, language barriers and cultural differences;

•seasonal reductions in business activity;

•expenses associated with localizing our products; and

•differing intellectual property laws.

We are subject to complex laws and regulations that apply to our international operations, such as data privacy and protection requirements, including GDPR, the Foreign Corrupt Practices Act, the UK Anti-Bribery Act and similar local laws prohibiting certain payments to government officials, banking and payment processing regulations and anti-competition regulations, among others. The cost of complying with these various, and sometimes conflicting, laws and regulations is substantial. We have implemented and continue to implement policies and procedures to ensure compliance with these laws and regulations, however, we cannot ensure that our employees, contractors, or agents will not violate our policies. Changing laws, regulations and enforcement actions in the United States and throughout the world could harm our business. If commercial and regulatory constraints in our international markets restrict our ability to conduct our operations or execute our strategic plan, our business may be adversely affected.

In addition, we are subject to risks associated with Brexit, given our operations in the United Kingdom and the European Union. Our operations and that of our merchants are highly integrated across the United Kingdom and the European Union, and we are highly dependent on the free flow of labor and goods in those regions. The ongoing uncertainty concerning trade between the United Kingdom and European Union nations could negatively impact our merchant and customer relationships and financial performance. In addition, future developments in the laws and regulations applicable to our operations in the United Kingdom could vary from those applicable to our operations in other European Union nations and make it more difficult for us to operate and adversely affect our financial results.

Our future success depends upon our ability to attract and retain high quality merchants and third-party business partners.

We must continue to attract and retain high quality merchants in order to increase profitability. A key priority of our strategy is to increase inventory on our marketplace, which depends on our ability to attract and retain merchants and the increase volume and breadth of supply. We are also focused on improving the merchant experience on our platform, including improving tools available to merchants to help grow their businesses. Further, COVID-19 has negatively impacted many of our merchants and the ultimate effect on their businesses and any post-COVID recovery is uncertain. We may not be able to retain or re-acquire these merchants in the future. In addition, as we transition our Goods category to a third-party marketplace model, we may not be able to maintain vendor relationships on comparable payment terms, margins or at all. If we are not able to effectively attract and retain merchants, third party partners or vendors, it could adversely affect our business and results of operations.

In addition, in most instances, we do not have long-term arrangements to guarantee the availability of deals that offer attractive quality, value and variety to customers or favorable payment terms to us. If merchants or third party partners decide that utilizing our services no longer provides an effective means of attracting new customers or selling their offerings, they may stop working with us or negotiate to pay us lower margins or fees. In addition, current or future competitors may accept lower margins, or negative margins, to secure offers that attract attention and acquire new customers. We also may experience attrition in our merchants resulting from several factors, including losses to competitors and merchant closures or merchant bankruptcies. If we are unable to attract and retain high quality merchants and third party partners in numbers sufficient to grow our business, or if merchants and third party partners are unwilling to offer products or services with compelling terms through our marketplace, our operating results may be adversely affected.

If we fail to retain our existing customers or acquire new customers, our operating results and business will be harmed.

We must continue to retain and acquire customers who make purchases on our platform in order to increase profitability. COVID-19 has negatively impacted our ability to attract and retain customers, and the timing of recovery and the pandemic's impact on long-term customer behavior is uncertain. Although we intend to focus on re-engaging and acquiring new customers as our business recovers from COVID-19, our efforts may not be successful. Further, as our customer base evolves, the composition of our customers may change in a manner that makes it more difficult to generate revenue to offset the loss of existing customers and the costs associated with acquiring and retaining customers and to maintain or increase our customers’ purchase frequency. If customers do not perceive our offerings to be attractive or if we fail to introduce new and more relevant deals or increase awareness and understanding of the offerings on our marketplace platform, we may not be able to retain or acquire customers at levels necessary to grow our business and profitability. In addition, changes to search engine algorithms or similar actions are not within our control and could adversely affect traffic to our websites and mobile applications. If we are unable to re-engage and acquire new customers in numbers sufficient to grow our business and offset the number of customers that have ceased to make purchases, or if new customers do not make purchases at expected levels, our profitability may decrease and our operating results may be adversely affected.

We operate in a highly competitive industry with relatively low barriers to entry and must compete successfully in order to grow our business.

Competition in our industry may increase in future periods. We compete against e-commerce sites that attempt to replicate our business model, companies that offer other types of advertising and promotional services to local businesses and companies who address only specific verticals in the local experiences market. In addition to such competitors, we may experience increased competition from other large businesses who offer deals similar to ours as an add-on to their core business. We also compete with other companies that offer digital coupons through

their websites or mobile applications. Further, we compete against other e-commerce companies that serve niche markets and interests, including within the local experiences market. In some of our categories, such as Travel and Goods, we compete against much larger companies who have more resources and significantly greater scale. In addition, we compete with traditional offline coupon and discount services, as well as newspapers, magazines and other traditional media companies who provide coupons and discounts on products and services.

We believe that our ability to compete successfully depends upon many factors both within and beyond our control, including the following:

•recovery from the impact of COVID-19 on our business;

•the size, composition and retention of our customer and merchant bases;

•density and quality of our inventory;

•delivery of a modern user experience for customers and modern experience and tools for merchants;

•mobile penetration;

•understanding local business trends;

•our ability to structure deals to generate positive return on investment for merchants;

•the timing and market acceptance of deals we offer, including the developments and enhancements to those deals offered by us or our competitors;

•our customer and merchant service and support efforts;

•selling and marketing efforts;

•ease of use, performance, price and reliability of services offered either by us or our competitors;

•our ability to improve customer purchase frequency and customer lifetime value;

•our ability to drive traffic to our marketplace;

•the number, quality and reliability of the digital coupons that can be accessed through our platform;

•the quality and performance of our merchants;

•our ability to cost-effectively manage our operations; and

•our reputation and brand strength relative to our competitors.

Some of our competitors have longer operating histories, greater financial, marketing and other resources and larger customer bases than we do. These factors may allow our competitors to benefit from their existing customer base with lower customer acquisition costs or to respond more quickly than we can to new or emerging technologies and changes in consumer habits. Further, COVID-19 may not have had a comparable impact on these competitors' businesses. In addition, our competitors may engage in more extensive research and development efforts, undertake more far-reaching marketing campaigns and adopt more aggressive pricing policies, which may allow them to build larger customer and/or merchant bases or generate revenue from their customer bases more effectively than we do. Our competitors may offer deals that are similar to the deals we offer or that achieve greater market acceptance than the deals we offer. This could attract customers away from our websites and mobile applications, reduce our market share and adversely impact our gross profit. In addition, we are dependent on some of our existing or potential competitors for display advertisements and other marketing initiatives to acquire new customers. Our ability to utilize their platforms to acquire new customers may be adversely affected if they choose to compete more directly with us or prevent us from using their services.

Our success is dependent upon our ability to provide a superior mobile experience for our customers and our customers' continued ability to access our offerings through mobile devices.

In the year ended December 31, 2020, over 75% of our global transactions were completed on mobile devices. While the focus on mobile is key to our long-term strategy, currently average purchase prices and conversion rates on mobile tend to be significantly lower than desktop. In order to continue to grow our mobile transactions and improve mobile conversion rates, it is critical that our applications are compatible with a range of mobile technologies, systems, networks and standards and that we provide a good, modern customer experience. Our business may be adversely affected if our customers choose not to access our offerings on their mobile

devices, we are not successful in increasing mobile conversion rates or if we fail to develop applications and product enhancements with adequate functionality and a positive customer experience on a wide range of mobile devices. In addition, the success of our mobile application depends on our continued ability to distribute it through mobile application marketplaces (e.g., an app store).

An increase in our refund rates or estimated liabilities with respect to unredeemed vouchers could adversely affect our financial results.

COVID-19 has had a significant impact on refunds. A further downturn in general economic conditions or extended period of low consumer confidence (including the continued impact of and recovery from COVID-19) could also increase our refund rates. An increase in our refund rates could significantly reduce our liquidity, profitability and financial results. We estimate future refunds based on historical refund experience by category. We assess the trends that could affect our estimates on an ongoing basis and make adjustments to the refund reserve calculations if it appears that changes in circumstances, including changes to our refund policies or general economic conditions, may cause future refunds to differ from our initial estimates. Our actual level of refund claims could prove to be greater than the level of refund claims we estimate. If our refund reserves are not adequate to cover future refund claims, this inadequacy could have a material adverse effect on our financial results. In addition, we may not be able to obtain reimbursement from merchants (particularly those negatively impacted by COVID-19) for refunds that we issue, which could have an adverse effect on our financial results.

In recent periods, we have increased our use of redemption payment terms with our North America merchants. In addition, we are required under the applicable revenue recognition standard to estimate variable consideration from unredeemed vouchers. As a result, a greater percentage of our transactions in North America than in prior periods will require us to use projections in order to estimate revenue and liabilities associated with unredeemed vouchers. If the estimates that we use in projecting the likelihood of vouchers being redeemed prove to be inaccurate, our liabilities with respect to unredeemed vouchers may be materially higher than the amounts shown in our financial statements, and our net income could be materially and adversely affected.

The loss of key members of our management team, or our failure to attract and retain other highly qualified personnel in the future could harm our business.

In order to be successful, we must attract, retain and motivate executives and other key employees, including those in managerial, technical and sales positions. Hiring and retaining qualified executives, engineers and qualified sales representatives are critical to our success, and competition for experienced and well qualified executives and employees can be intense. In 2020, we experienced significant leadership changes, including appointing a new Interim Chief Executive Officer, a new Chief Financial Officer and the departure of our Chief Operating Officer. Executive leadership transitions can be difficult to manage and could cause disruption to our business. Further, disruption in our business due to COVID-19, the execution of our restructuring plan and implementation of our strategy, including phase down and transition of our Goods category, may make it more difficult to attract and retain talent. In order to attract and retain executives and other key employees in a competitive marketplace, we must provide a competitive compensation package, including cash and equity-based compensation. We currently utilize restricted stock units and performance share units as our forms of share-based incentive compensation. If the anticipated value of such equity-based incentive awards does not materialize, if our equity-based compensation otherwise ceases to be viewed as a valuable benefit or if our total compensation package is not viewed as competitive, our ability to attract, retain and motivate executives and key employees could be weakened. The failure to successfully hire and retain executives and key employees or the loss of any executives and key employees could have a significant impact on our operations.

Failure to deal effectively with fraudulent transactions and customer disputes would increase our loss rate and harm our business.

We sell a variety of offerings to consumers through our marketplace, including our vouchers and digital coupon offerings with unique identifier codes. It is possible that consumers or other third parties will seek to create counterfeit vouchers or codes, fraudulent accounts or fraudulent banking information in order to improperly purchase or redeem goods and services. While we use advanced anti-fraud technologies, criminals may attempt to circumvent our anti-fraud systems using increasingly sophisticated methods. In addition, our service could be subject to employee fraud or other internal security breaches or merchant fraud, and we may be required to reimburse customers or merchants for any funds stolen or revenue lost as a result of such breaches. If merchants

are affected by buyer fraud or other types of fraud, they could also request reimbursement, or stop offering goods or services on our marketplaces.

Although we have not incurred significant losses from fraud or counterfeit vouchers or digital codes in the past, we could incur significant losses from such activities in future periods. Additionally, we may incur losses from claims that the customer did not authorize a purchase, from credit card fraud, from merchant fraud, from erroneous transmissions, and from customers who have closed bank accounts or have insufficient funds in them to satisfy payments. We also may incur losses as a result of purchases made with fraudulent credit card information, even if the associated financial institution approved payment of the transaction. In addition to the direct costs of any such losses, if the losses are related to credit card transactions and become excessive, they could potentially result in our losing the right to accept credit cards for payment. If we were unable to accept credit cards for payment, we would suffer substantial reductions in revenue, which would cause our business to suffer. While we have taken measures to detect and reduce the risk of fraud, these measures need continual improvement and may not be effective against new and continually evolving forms of fraud and may not timely detect fraud. If we are unable to effectively combat fraudulent transactions or if we otherwise experience increased levels of fraud or disputed credit card payments, our business could materially suffer.

We are subject to payments-related risks.

We accept payments using a variety of methods, including credit cards, debit cards and gift certificates. As we offer new payment options to customers, we may be subject to additional regulations, compliance requirements and fraud. For certain payment methods, including credit and debit cards, we pay interchange and other fees, which may increase over time and raise our operating costs and lower profitability. In addition, our credit card and other payment processors generally have broad discretion to impose receivable holdback or reserve requirements and could do so in the future. Any material increase in receivable holdback or reserve requirements could have a material impact on our cash flow and available liquidity. In the event our strategy is unsuccessful or our business deteriorates significantly due to COVID-19 or other factors, these payment processors could increase holdback amounts due to concerns with our financial condition, which could adversely affect our liquidity. We rely on third parties to provide payment processing services, including the processing of credit cards and debit cards, and it could disrupt our business if these companies become unwilling or unable to provide these services to us. We are also subject to payment card association operating rules, certification requirements and rules governing electronic funds transfers, which could change or be reinterpreted to make it difficult or impossible for us to comply. If we fail to comply with these rules or requirements, we may be subject to fines and higher transaction fees and lose our ability to accept credit and debit card payments from customers or facilitate other types of online payments, and our business and operating results could be adversely affected.

We are also subject to or voluntarily comply with a number of other laws and regulations relating to money laundering, international money transfers, privacy and information security and electronic fund transfers. If we were found to be in violation of applicable laws or regulations, we could be subject to civil and criminal penalties. In addition, events affecting our third-party payment processors or our integration with them, including cyber-attacks, Internet or other infrastructure or communications impairment or other events that could interrupt the normal operation of our payment processors or our integration with them, or result in unauthorized access to customer information, could have a material adverse effect on our business.

Risks Related to Technology and Cybersecurity

We rely on email, Internet search engines and mobile application marketplaces to drive traffic to our marketplace.

The traffic to our websites and mobile applications, including from consumers responding to our emails and SEO, has declined in recent years. As such, we must focus on diversifying our sources of traffic, including by developing sources of traffic in addition to email and SEO and optimizing the efficiency of our marketing spending. If we are not able to diversify our sources of traffic and acquire and retain customers efficiently, our business and results of operations could be adversely affected.

Email continues to be a significant source of organic traffic for us. If email providers or Internet service providers implement new or more restrictive email or content delivery or accessibility policies, including with respect to net neutrality, it may become more difficult to deliver emails to our customers or for customers to access our site

and services. For example, certain email providers, including Google, categorize our emails as "promotional," and these emails are directed to an alternate, and less readily accessible, section of a customer's inbox. If email providers materially limit or halt the delivery of our emails, or if we fail to deliver emails to customers in a manner compatible with email providers’ email handling or authentication technologies, our ability to contact customers through email could be significantly restricted. In addition, if we are placed on "spam" lists or lists of entities that have been involved in sending unwanted, unsolicited emails, our operating results and financial condition could be substantially harmed.

We also rely heavily on Internet search engines to generate traffic to our websites, principally through SEM and SEO. The number of consumers we attract from search engines to our platform is due in large part to how and where information from, and links to, our websites are displayed on search engine results pages. The display, including rankings, of search results can be affected by a number of factors, many of which are not in our control and may change at any time. Search engines frequently update and change the logic that determines the placement and display of the results of a user’s search, such that the purchased or algorithmic placement of links to our websites can be negatively affected. In addition, a search engine could, for competitive or other purposes, alter its search algorithms or results causing our websites to place lower in search query results. If a major Internet search engine changes its algorithms in a manner that negatively affects the search engine ranking it could create additional traffic headwinds for us and negatively affect our results of operations.

We also rely on mobile marketplace operators (i.e., app store operators) to drive downloads of our mobile application. If any mobile marketplace operator determines that our mobile application is non-compliant with its vendor policies, the operator may revoke our rights to distribute through its marketplace or refuse to permit a mobile application update at any time. These operators may also change their mobile application marketplaces in a way that negatively affects the prominence of, or ease with which users can access, our mobile application. Such actions may adversely impact the ability of customers to access our offerings through mobile devices, which could have a negative impact on our business and results of operations.

We may be subject to breaches of our information technology systems, which could harm our relationships with our customers, merchants and third-party business partners, subject us to negative publicity and litigation, and cause substantial harm to our business or brand.

In operating a global online business, we and our third-party service providers maintain significant proprietary information and manage large amounts of personal data and confidential information about our employees, customers and merchants. We and such service providers are at constant risk of cyber-attacks or cyber intrusions via the Internet, computer viruses, break-ins, malware, phishing attacks, hacking, denial-of-service attacks or other attacks and similar disruptions from the unauthorized use of or access to computer systems (including from internal and external sources). These types of incidents continue to be prevalent and pervasive across industries, including in our industry, and such attacks on our systems have occurred in the past and are expected to occur in the future. In addition, we expect the sophistication of the perpetrators of these attacks to continue to expand and could include nation-state actors. Further, we believe that we are a compelling target for such attacks as a result of the high profile of our brand and the amount and type of information we maintain relating to our customers and merchants. Any such incident could lead to interruptions, delays or website outages, causing loss of critical data or the unauthorized disclosure or use of personally identifiable or other confidential information.

Any failure to prevent or mitigate cybersecurity breaches or other improper access to, or disclosure of, our data or confidential information, including non-public financial information, could result in the loss or misuse of such data or information, negatively impacting customers’, merchants’ and third-party business partners' confidence in the security of our services and potentially resulting in significant customer or merchant attrition, a decline in customer purchase frequency, litigation and/or regulatory investigations, and/or damage to our brand and reputation.

Our risk and exposure to these matters remains heightened because of, among other things, the evolving nature of these threats, our prominent size and scale, the large number of transactions that we process, our geographic footprint and international presence, the complexity of our systems, our number of employees, the jurisdictions in which we operate and the various and evolving laws and regulatory schemes governing data and data protection applicable to us, the extent to which our current systems, controls, processes and practices permit us to detect, log and monitor security events, our use of cloud based technologies and the outsourcing of some of our business operations.

Although cybersecurity and the continued development and enhancement of our controls, processes and practices designed to protect our systems, computers, software, data and networks from attack, damage or unauthorized access are a high priority for us, our activities and investment may not be deployed quickly enough or successfully protect our systems against all vulnerabilities, including technologies developed to bypass our security measures or zero day vulnerabilities. In addition, outside parties may attempt to fraudulently induce employees, merchants or customers to disclose access credentials or other sensitive information in order to gain access to our systems and networks. We also may be subject to additional vulnerabilities as we integrate the systems, computers, software and data of acquired businesses and third-party business partners into our networks and separate the systems, computers, software and data of disposed businesses from our networks.

We maintain a cybersecurity risk management program that is overseen by our Vice President, Information Security, who reports directly to our Chief Technology Officer. Our Vice President, Information Security regularly reports to the Audit Committee on the state of our cybersecurity program and provides updates on cybersecurity matters. We also conduct an annual cybersecurity review with our Board of Directors. As part of our cybersecurity risk management program, we employ security practices to protect and maintain the systems located at our data centers and hosting providers, invest in intrusion, anomaly, and vulnerability detection tools and engage third-party security firms to test the security of our websites and systems. In addition, we regularly evaluate and assess our systems and the controls, processes and practices to protect those systems and also conduct penetration testing against our own system. The evaluations, assessments and testing identify areas of potential weakness in, and suggested improvements to, the maturity of our systems, processes, and risk management framework as well as vulnerabilities in those systems, processes, and risk management framework that could be attacked and exploited to access and acquire proprietary and confidential information, including information about our customers and merchants. There are no assurances that our cybersecurity risk mitigation program or actions and investments to improve the maturity of our systems, processes and risk management framework or remediate vulnerabilities will be sufficient or completed quickly enough to prevent or limit the impact of any cyber intrusion. In addition, in the future we may be required to expend significant additional resources to modify or enhance our protective measures, controls and systems or to improve the maturity of our systems, processes and risk management framework, or investigate or remediate any information security vulnerabilities. These improvements, modifications and enhancements may take significant time to implement. Further, the sophistication of potential attacks or the capabilities of our systems and processes may not permit us to detect the occurrence of cyber incidents until significant data loss has occurred. Moreover, because the techniques used to gain access to or sabotage systems often are not recognized until launched against a target, we may be unable to anticipate the methods necessary to defend against these types of attacks and we cannot predict the extent, frequency or impact these problems may have on us. Any actual breach, the perceived threat of a breach or a perceived breach, could cause our customers, merchants and payment card processors to cease doing business with us or do business with us less frequently, subject us to lawsuits (including claims for damages), investigations, regulatory fines or other action or liability or damage to our brand and reputation, which would harm our business, financial condition and results of operations.

Our business depends on our ability to maintain and improve the technology infrastructure necessary to send our emails and operate our websites, mobile applications and transaction processing systems, and any significant disruption in service on our email network infrastructure, websites, mobile applications or transaction processing systems could result in a loss of customers or merchants.

Customers access our marketplaces through our websites and mobile applications, as well as via emails that are often targeted by location, purchase history and personal preferences. Customers can also access our deal offerings indirectly through third-party search engines. Our reputation and ability to acquire, retain and serve our current and potential customers are dependent upon the reliable performance of our websites, mobile applications, email delivery and transaction processing systems and the underlying network infrastructure. Our systems may not be adequately designed with the necessary reliability and redundancy to avoid performance delays or outages that could be prolonged and harmful to our business. If our websites or mobile applications are unavailable when users attempt to access them, or if they do not load as quickly as expected, users may not return as often in the future, or at all. We have spent and expect to continue to spend substantial amounts on data centers and equipment, cloud-based technology and related network infrastructure and services to handle the traffic on our websites and mobile applications and to help shorten the time of or prevent system interruptions. The operation of these systems is expensive and complex and could result in operational failures. While resiliency and redundancy are considerations in the design and operation of Groupon's systems, interruptions, delays or failures in these systems, whether due to earthquakes, adverse weather conditions, other natural disasters, power loss, computer viruses, cybersecurity attacks, physical break-ins, terrorism, errors in our software or otherwise, could be prolonged and could affect the

security or availability of our websites and applications, and prevent our customers from accessing our services. If we do not maintain or expand our network infrastructure successfully or if we experience operational failures or prolonged disruptions or delays in the availability of our systems, we could lose current and potential customers and merchants, which could harm our operating results and financial condition.

In addition, a portion of our network infrastructure is hosted by third-party providers. We also rely on a variety of tools and third-party commercial partners to provide certain services and offerings (e.g., booking and ticketing tools). Any disruption or failure of these providers, tools and/or other third parties to handle existing or increased traffic and transactions could significantly harm our business. Any financial or other difficulties these providers face may adversely affect our business, and we exercise little control over these providers, which increases our vulnerability to problems with the services they provide.

As we increase our reliance on cloud-based applications and platforms to operate and deliver our products and services, any disruption or interference with these platforms could adversely affect our financial condition and results of operations.

We rely on cloud-based applications and platforms for critical business functions. We also are migrating a significant portion of our computing infrastructure to third party hosted cloud-based computing platforms. If we are not able to complete this migration on our expected timeline, we could incur additional costs. Further, these migrations can be risky and may cause disruptions to the availability of our products due to service outages, downtime or other unforeseen issues that could increase our costs. We also may be subject to additional risk of cybersecurity breaches or other improper access to our data or confidential information during or following migrations to cloud-based computing platforms. In addition, cloud computing services may operate differently than anticipated when introduced or when new versions or enhancements are released. As we increase our reliance on cloud-based computing services, our exposure to damage from service interruptions may increase. In the event any such issues arise, it may be difficult for us to switch our operations from our primary cloud-based providers to alternative providers. Further, any such transition could involve significant time and expense and could negatively impact our ability to deliver our products and services, which could harm our financial condition and results of operations.

Risks Related to Transactions and Investments

Acquisitions, dispositions, joint ventures and strategic investments could result in operating difficulties, dilution and other consequences.

We routinely evaluate and consider a wide array of potential strategic transactions, including acquisitions and dispositions of businesses, joint ventures, technologies, services, products and other assets and minority investments. The pursuit and consummation of such transactions can result in operating difficulties, dilution, management distraction and other potentially adverse consequences. In the past, we have acquired and divested a number of companies and may complete additional transactions in the future.

Acquisitions involve significant risks and uncertainties, including uncertainties as to the future financial performance of the acquired business and the performance of acquired customers, valuation of the acquired business and integration risks such as difficulties integrating acquired personnel into our business, the potential loss of key employees, customers or suppliers, difficulties in integrating different computer, payment and accounting systems and exposure to unknown or unforeseen liabilities of acquired companies. In addition, the integration of an acquisition could divert management's time and our resources. If we pay for an acquisition or a minority investment in cash, it would reduce our cash available for operations or cause us to incur debt, and if we pay with our stock, it could be dilutive to our stockholders. Additionally, we do not have the ability to exert control over our minority investments, and therefore we are dependent on others in order to realize their potential benefits. Dispositions and attempted dispositions also involve significant risks and uncertainties, such as the risk of destabilizing the applicable operations, the loss of key personnel, the terms and timing of any dispositions, the ability to obtain necessary governmental or regulatory approvals, post-disposal disputes and indemnification obligations and risks and uncertainties with respect to the separation of disposed operations, including, for example, transition services, access by purchasers to certain of our systems and tools during transition periods, the migration of data and separation of systems, data privacy matters and misuse of trademarks and intellectual property. We may be unable to successfully complete potential strategic transactions or dispositions on a timely basis or at all, or we may not realize the anticipated benefits of any of our strategic transactions in the time frame expected or at all.

We do not have the ability to exert control over our minority investments, and therefore we are dependent on others in order to realize their potential benefits.

We currently hold non-controlling minority investments in entities and we may make additional strategic minority investments in the future. Such minority investments inherently involve a lesser degree of control over business operations, thereby potentially increasing the financial, legal, operational and/or compliance risks associated with the investments. Other investors in these entities may have business goals and interests that are not aligned with ours, or may exercise their rights in a manner in which we do not approve. These circumstances could lead to delayed decisions or disputes and litigation with those other investors, all of which could have a material adverse impact on our reputation, business, financial condition and results of operations.

If these entities seek additional financing, such financing transactions may result in further dilution of our ownership stakes and such transactions have and in the future may occur at lower valuations than the investment transactions through which we acquired such interests, which could significantly decrease the fair values of our investments in those entities. The lack of availability of financing on commercially reasonable terms or a decline in the business performance, financial condition and competitive environment of any of our minority investments could result in lower financial results or forecasted results, which also could significantly decrease the fair values of our investments in those entities. Further, we have made an irrevocable election to account for our investments in Monster LP and other entities at fair value with changes in fair value reported in earnings. Our election to apply fair value accounting to those investments has and may continue to cause fluctuations in our earnings from period to period.

Risks Related to Our Brand and Intellectual Property

We allow third parties to sell products via our site and services and purchase and sell some products from indirect suppliers, which increase our risk of litigation and other losses.

We allow third party merchants to sell products to our customers via our marketplace platform in North America, and we expect to fully transition our International Goods category to a third-party marketplace model in 2021. In International, we currently source some merchandise for sale in our Goods category from indirect suppliers and third-party distributors, and we take title to some goods before we offer them for sale to our customers. In addition, by allowing third parties to sell products on our platform and sourcing merchandise from parties other than the brand owners, we are subject to increased intellectual property and other risks, including that the merchandise may be of disputed authenticity, obtained or sourced outside of the rights holder's established distribution channels or damaged, which could result in potential liability under applicable laws, regulations, agreements and orders and increase the amount of returned merchandise or customer refunds. Further, we may be found to be directly liable for actions by third party merchants who sell goods on our site. In addition, brand owners or regulators may take legal action against us. Even if we prevail, any such legal action could result in costly litigation, generate adverse publicity for us, and have a material adverse impact on our business, financial condition, results of operations, brand and reputation. Further, in any such matter, we may not be entitled to indemnification from our supplier or merchant, or able to effectively enforce the supplier’s or merchant’s contractual indemnification obligations.

We may be subject to substantial liability claims and damage to our brand and reputation if people or property are harmed by the products or services offered through our marketplace.

Some of the products and services offered through our marketplace may expose us to liability claims relating to personal injury, death, negligence, intentional misconduct, assault, abuse or environmental or property damage. Certain merchants and third parties sell products and offer services using our marketplace that based on the type of product or service, may increase our exposure to substantial claims and litigation, especially if these merchants or third-party sellers do not have sufficient protection from such claims. Although we believe we are not liable for the goods or services that merchants or third-parties offer through our marketplace, there is no assurance that a court would rule in our favor on such issues. Further, while we maintain liability insurance, we cannot be certain our coverage will apply to the claims at issue, be adequate for liabilities actually incurred or that insurance will continue to be available to us on economically reasonable terms, or at all. In addition, some of our agreements with vendors, merchants and third-party sellers do not indemnify us from certain liability and costs or we may not be able to effectively enforce our contractual indemnification rights. Claims relating to products or services offered through our marketplace also could result in significant damage to our brand and reputation regardless of whether we are ultimately liable for any such claims.

Our processes and procedures for onboarding merchants and third-party sellers also may expose us to liability claims or damage to our brand and reputation if the processes or procedures are deemed inadequate. Additionally, while we maintain multiple channels through which our customers can submit feedback or complaints about their experiences with merchants and other third-party sellers on our platform, because our customers often deal directly with the sellers, pertinent feedback may not be provided to us. Moreover, our evaluation of any customer feedback or complaints we receive is subjective based on the information, which is sometimes very limited, that our customers provide, and we may not take action in response to feedback or complaints. If our systems and procedures with respect to any such feedback or complaints are determined to be inadequate or any action or inaction is found to be inadequate, including, by way of example, not discontinuing on a timely basis offers of deals with merchants or sellers that have been the subject of material complaints, we could face substantial additional liability and damage to our brand and reputation for the misconduct of such merchants or third-party sellers.

We may not be able to adequately protect our intellectual property rights or may be accused of infringing intellectual property rights of third parties.

We regard our trademarks, service marks, copyrights, patents, trade dress, trade secrets, proprietary technology, merchant lists, subscriber lists, sales methodology and similar intellectual property as critical to our success, and we rely on trademark, copyright and patent law, trade secret protection and confidentiality and/or license agreements with our employees and others to protect our proprietary rights. Effective intellectual property protection may not be available in every country in which our deals are made available. We also may not be able to acquire or maintain appropriate domain names or trademarks in all countries in which we do business. Furthermore, regulations governing domain names may not protect our trademarks and similar proprietary rights. We may be unable to prevent third parties from acquiring and using domain names or trade names that are similar to, infringe upon or diminish the value of our trademarks and other proprietary rights. We may be unable to prevent third parties from using and registering our trademarks, or trademarks that are similar to, or diminish the value of, our trademarks in some countries.

We may not be able to discover or determine the extent of any unauthorized use of our proprietary rights. Third parties that license our intellectual property rights also may take actions that diminish the value of our proprietary rights or reputation. The protection of our intellectual property may require the expenditure of significant financial and managerial resources. Moreover, the steps we take to protect our intellectual property may not adequately protect our rights or prevent third parties from infringing or misappropriating our proprietary rights. We are currently subject to multiple lawsuits and disputes related to our intellectual property and service offerings. We may in the future be subject to additional litigation and disputes. The costs of engaging in such litigation and disputes are considerable, and there can be no assurances that favorable outcomes will be obtained.

We are currently subject to third-party claims that we infringe upon proprietary rights or trademarks and expect to be subject to additional claims in the future. Such claims, whether or not meritorious, may result in the expenditure of significant financial and managerial resources, injunctions against us or the payment of damages by us. We may need to obtain licenses from third parties who allege that we have infringed their rights, but such licenses may not be available on terms acceptable to us or at all. These risks have been amplified by the increase in third parties whose sole or primary business is to assert such claims.

Our business depends on a strong brand, and if we are not able to maintain and enhance our brand, our ability to expand our base of customers and merchants could be impaired and our business and operating results could be harmed.

We believe that the brand identity that we have developed has significantly contributed to the success of our business. We also believe that maintaining and enhancing the "Groupon" brand is critical to expanding our base of customers and merchants. In addition, maintaining and enhancing our brand may require us to make substantial additional investments over time and these investments may not be successful. Further, due to the impact of COVID-19, we significantly decreased our marketing spend in 2020 and delayed certain brand marketing investments, which could have an adverse impact on our business in the future. If we fail to promote, maintain and protect the "Groupon" brand, our business, operating results and financial condition may be adversely affected. We anticipate that, as the local experiences market becomes increasingly competitive, maintaining and enhancing our brand may become more difficult and expensive. Maintaining and enhancing our brand will depend largely on our ability to continue to provide reliable, trustworthy and high quality inventory on our marketplace, which we may not do successfully.

We receive a high degree of media coverage around the world. Unfavorable publicity or consumer perception of our websites, mobile applications, practices or service offerings, or the offerings of our merchants or their products, could adversely affect our reputation, resulting in difficulties in recruiting, decreased revenue and a negative impact on the number of merchants we feature and the size of our customer base, the loyalty of our customers and the number and variety of our offerings. As a result, our business, financial condition and results of operations could be materially and adversely affected.

Risks Related to Legal, Regulatory, Privacy and Tax Matters

We are involved in pending litigation and other claims and an adverse resolution of such matters may adversely affect our business, financial condition, results of operations and cash flows.

We are involved from time to time in litigation regarding, among other matters, patent and other intellectual property claims, consumer claims, contract disputes with merchants and vendors, employment claims, and securities law claims. Litigation, dispute resolution proceedings and investigations can be expensive, time-consuming and disruptive to normal business operations. The results of complex legal proceedings are often uncertain and difficult to predict. An unfavorable outcome with respect to any of these lawsuits or claims could have a material adverse effect on our business, financial condition, results of operations and cash flows. For additional information, see Item 8, Note 12, Commitments and Contingencies, to the consolidated financial statements.

The COVID-19 pandemic may also result in additional litigation including disputes with merchants, customers, vendors, and others over refunds, payments, and contract terms. We may also be the target of tort or negligence claims relating to incidents, injuries or illnesses incurred by customers visiting merchants. Although we disclaim legal liability for such claims and advise all of our customers that the merchants are solely responsible to purchasers for the care and quality of the advertised goods and services, there is no assurance that a court would rule in our favor on such issues. We also hold indemnity rights with respect to merchants in relation to any such claims, but there is no assurance that merchants will be sufficiently capitalized to cover all incurred losses.

Although we maintain insurance, we cannot be certain our coverage will apply to the claims at issue, be adequate for any liability incurred or continue to be available to us on economically reasonable terms, or at all. The cost of insurance, including directors and officer insurance, errors and omission insurance, product liability, general liability insurance and other types of policies, could increase at any time or become more limited based on market conditions or other circumstances outside of our control. Furthermore, certain insurance coverages may not be available for specific risks faced by us. Insurance premium increases and increased risk due to lack of availability, reduced coverage or increased deductibles could have a material adverse effect on our business, financial condition, results of operations and cash flows.

The application of certain laws and regulations, including, among other laws, the CARD Act and similar state and foreign laws, may harm our business and results of operations.

The application of certain laws and regulations to vouchers is uncertain. Vouchers may be considered gift cards, gift certificates, stored value cards or prepaid cards and therefore governed by, among other laws, the CARD Act, and state laws governing gift cards, stored value cards and coupons, and, in certain instances, potentially subject to unclaimed and abandoned property laws. Other foreign jurisdictions have similar laws in place, in particular European jurisdictions where the European E-Money Directive regulates the business of electronic money institutions. Many of these laws contain provisions governing the use of gift cards, gift certificates, stored value cards or prepaid cards, including specific disclosure requirements and prohibitions or limitations on the use of expiration dates and the imposition of certain fees. For example, if vouchers are subject to the CARD Act and are not included in the exemption for promotional programs, it is possible that the purchase value, which is the amount equal to the price paid for the voucher, or the promotional value, which is the add-on value of the voucher in excess of the price paid, or both, may not expire before the later of (i) five years after the date on which the voucher was issued; (ii) the voucher’s stated expiration date (if any); or (iii) a later date provided by applicable state law. In the event that it is determined that vouchers sold through our platform are subject to the CARD Act or any similar state or foreign law or regulation, and are not within various exemptions that may be available under the CARD Act or under some of the various state or foreign jurisdictions, our liabilities with respect to unredeemed vouchers may be materially higher than the amounts shown in our financial statements and we may be subject to additional fines and penalties.

In addition, from time to time, we may be notified of additional laws, or developments in existing laws and regulations that governmental organizations or others may claim should be applicable to our business, or that otherwise affect our operations. If we are required to alter our business practices, or there are other market changes, as a result of any laws and regulations, our revenue could decrease, our costs could increase and our business could otherwise be harmed. In addition, the costs and expenses associated with defending any actions related to, or otherwise reacting to, such legal or regulatory developments, and any related payments (including penalties, judgments, settlements or fees) could adversely impact our profitability. To the extent that we expand into new lines of business and new geographies, we will become subject to additional laws and regulations.

If we are required to materially increase the liability recorded in our financial statements with respect to unredeemed vouchers our results of operations could be materially and adversely affected.

In certain states and foreign jurisdictions, vouchers may be considered a gift card. Some of these states and foreign jurisdictions include gift cards under their unclaimed and abandoned property laws which require companies to remit to the government the full value or a portion of the value of the unredeemed balance on the gift cards after a specified period of time (generally between one and five years) and impose certain reporting and record-keeping obligations. We do not remit any amounts relating to unredeemed vouchers based on our assessment of applicable laws. The analysis of the potential application of the unclaimed and abandoned property laws to vouchers is complex, involving an analysis of constitutional and statutory provisions and factual issues, including our contractual relationship with customers and merchants. In recent periods, we increased our use of redemption payment terms with our North America merchants. The determinations we make with respect to variable consideration that we earn on those transactions may be subject to the laws described above. In the event that one or more states or foreign jurisdictions successfully challenges our position on the application of its unclaimed and abandoned property laws to vouchers, our liabilities with respect to unredeemed vouchers, including any resulting penalties and interest, may be materially higher than the amounts shown in our financial statements which could have a material adverse impact on our results of operations.

Government regulation of the Internet and e-commerce is evolving, and unfavorable changes or failure by us to comply with these regulations could substantially harm our business and results of operations.

We are subject to general business regulations and laws as well as regulations and laws specifically governing the Internet and e-commerce. Existing and future regulations and laws could impede the growth of the Internet or other online services. These regulations and laws may involve taxation, tariffs, subscriber privacy, anti-spam, data protection, content, reference pricing, copyrights, distribution, communications, consumer protection, the provision of online payment services and the characteristics and quality of services. The application of existing laws governing issues such as property ownership, sales and other taxes, libel and personal privacy to the Internet is not clear as the vast majority of these laws were adopted prior to the advent of, and do not contemplate or address the unique issues raised by, the Internet or e-commerce. In addition, it is possible that governments of one or more countries may seek to censor, or entirely block access to the content available on our websites, mobile applications, or marketing emails. Adverse legal or regulatory developments also could substantially harm our business. In particular, in the event that we are restricted, in whole or in part, from operating in one or more countries, our ability to retain or increase our customer base may be adversely affected and we may not be able to maintain or grow our gross profit as anticipated.

Failure to comply with federal, state and international privacy laws and regulations, or the expansion of current or the enactment of new privacy laws or regulations, could adversely affect our business.

A variety of federal, state and international laws and regulations govern the collection, use, retention, sharing and security of consumer data. The existing privacy-related laws and regulations are evolving and subject to potentially differing interpretations. In addition, various federal, state and foreign legislative and regulatory bodies may expand current or enact new laws regarding privacy matters. For example, GDPR requires companies to satisfy requirements regarding the handling of personal and sensitive data, including its collection, use, protection and the ability of persons whose data is stored to correct or delete such data about themselves. The CCPA also regulates the collection and use of consumers' data. Complying with the GDPR, CCPA and similar laws and regulations may cause us to incur substantial operational costs or require us to change our business practices. Further, despite our diligent efforts to comply with these laws and regulations, we may not be successful either due

to internal or external factors such as resource allocation limitations or a lack of vendor cooperation. Noncompliance could result in proceedings against us by governmental entities or others and fines. For example, fines under GDPR could be up to the greater of €20 million or 4% of annual global revenue and damage our reputation and brand. As a result of GDPR, CCPA and similar laws and regulations,we may experience difficulty retaining or obtaining new customers due to the compliance cost, potential risk exposure and portability of customer data. We also may find it necessary to establish and maintain systems and procedures to comply with these evolving laws and regulations that involve substantial expense and distraction from other aspects of our business. Additionally, there could be uncertainty as to how to comply with privacy laws, in various jurisdictions such as country or state-specific laws that may conflict with or deviate from privacy directives, such as GDPR, CCPA or future laws and regulations.

We have posted privacy policies and practices concerning the collection, use and disclosure of subscriber data on our websites and applications. Several Internet companies have incurred substantial penalties for failing to abide by the representations made in their privacy policies and practices. In addition, several states have adopted legislation that requires businesses to implement and maintain reasonable security procedures and practices to protect sensitive personal information and to provide notice to consumers in the event of a security breach resulting in a loss or likely loss of personal information. Any failure, or perceived failure, by us to comply with our posted privacy policies or with any data-related consent orders, Federal Trade Commission requirements or orders or other federal, state or international privacy or consumer protection-related laws, regulations or industry self-regulatory principles could result in claims, proceedings or actions against us by governmental entities or other third-parties or other liabilities, which could adversely affect our business. In addition, a failure or perceived failure to comply with industry standards or with our own privacy policies and practices could result in a loss of subscribers or merchants and adversely affect our business. Federal, state and international governmental authorities continue to evaluate the privacy implications inherent in the use of third-party web "cookies" for tracking and behavioral advertising. The regulation of these cookies and other current online advertising practices could adversely affect our business.

Misclassification or reclassification of our independent contractors or employees could increase our costs and adversely impact our business.

In the United States, our workers are classified as either employees or independent contractors, and if employees, as either exempt from overtime or non-exempt (and therefore overtime eligible). United States regulatory authorities and private parties have recently asserted within several industries that some independent contractors should be classified as employees and that some exempt employees, including those in sales-related positions, should be classified as non-exempt based upon the applicable facts and circumstances and their interpretations of existing rules and regulations. If we are found to have misclassified employees as independent contractors or non-exempt employees as exempt, we could face penalties and have additional exposure under federal and state tax, workers’ compensation, unemployment benefits, labor, employment and tort laws, including for prior periods, as well as potential liability for employee overtime and benefits and tax withholdings. Legislative, judicial, or regulatory (including tax) authorities could also introduce proposals or assert interpretations of existing rules and regulations that would change the classification of a significant number of independent contractors doing business with us from independent contractor to employee and a significant number of exempt employees to non-exempt. A reclassification in either case could result in a significant increase in employment-related costs such as wages, benefits and taxes as well as punitive damages in any related litigation. The costs associated with employee classification, including any related regulatory action or litigation, could have a material adverse effect on our results of operations and our financial position.

We may suffer liability as a result of information or content retrieved from or transmitted over the Internet and claims related to our service offerings.

We may be, and in certain cases have been, sued for defamation, civil rights infringement, negligence, patent, copyright or trademark infringement, invasion of privacy, personal injury, product liability, breach of contract, unfair competition, discrimination, antitrust reference pricing or other legal claims relating to information or content that is published or made available on our websites or service offerings we make available (including provision of an application programming interface platform for third parties to access our website, mobile device services and geolocation applications). This risk is enhanced in certain jurisdictions outside the United States, where our liability for such third-party actions may be less clear. In addition, we could incur significant costs in investigating and defending such claims, even if we ultimately are not found liable. If any of these events occurs, our business could be materially and adversely affected.

We are subject to risks associated with information disseminated through our websites and mobile applications, including consumer data, content that is produced by our editorial staff and errors or omissions related to the offerings on our marketplaces. Such information, whether accurate or inaccurate, may result in our being sued by our merchants, subscribers or third parties and as a result our results of operations and our financial position could be materially and adversely affected.

We may have exposure to greater than anticipated tax liabilities.

We are subject to income taxes in the United States (federal, state, and local) and numerous foreign jurisdictions. Tax laws, regulations, and administrative practices in various jurisdictions may be subject to significant change due to economic, political, and other conditions, and significant judgment is required in evaluating and estimating our provision and accruals for these taxes. Our income tax obligations are based on our corporate operating structure, including the manner in which we develop, value and use our intellectual property and the scope of our international operations.

The tax laws applicable to our domestic and international business activities, including the laws of the United States and other jurisdictions, are subject to interpretation. The taxing authorities of the jurisdictions in which we operate may challenge our methodologies for valuing developed technology or intercompany arrangements, which could potentially increase our worldwide effective tax rate and harm our financial position and results of operations. In addition, there are many transactions that occur during the ordinary course of business for which the ultimate tax determination is uncertain. Our effective tax rates could be adversely affected by earnings being lower than anticipated in jurisdictions where we have lower statutory rates and higher than anticipated in jurisdictions where we have higher statutory rates, losses incurred in jurisdictions for which we are not able to realize the related tax benefits, changes in foreign currency exchange rates, entry into new businesses and geographies and changes to our existing businesses, acquisitions and investments, changes in our deferred tax assets and liabilities and their valuation and changes in the relevant tax, accounting and other laws, regulations, administrative practices, principles and interpretations, including fundamental changes to the tax laws applicable to corporate multinationals. Developments in an audit, litigation or the relevant laws, regulations, administrative practices, principles and interpretations could have a material effect on our financial position, operating results and cash flows in the period or periods for which that development occurs, as well as for prior and subsequent periods.

We also are subject to regular review and audit by both U.S. (federal, state. local) and foreign tax authorities. In particular, we currently are, and expect to continue to be, subject to numerous federal, state and international tax audits relating to income, transfer pricing, sales, VAT and other tax liabilities. Some of these pending and future audits could involve significant liabilities and/or penalties. We are subject to claims for tax assessments by foreign jurisdictions, including a proposed assessment for $126.4 million (inclusive of estimated incremental interest from the original assessment). We believe that the assessment, which primarily relates to transfer pricing on transactions occurring in 2011, is without merit and we intend to vigorously defend ourselves in that matter. See Item 8, Note 17, Income Taxes, for additional information. Any adverse outcome of such a review or audit could have a significant negative effect on our financial position and results of operations. In addition, the determination of our worldwide provision for income taxes and other tax liabilities requires significant judgment by management, and there are many transactions where the ultimate tax determination is uncertain. Although we believe that our estimates are reasonable, the ultimate tax outcome may differ from the amounts recorded in our financial statements and may materially affect our financial results in the period or periods for which such determination is made.

The adoption of tax reform policies, including the enactment of legislation or regulations implementing changes in the tax treatment of companies engaged in Internet commerce and U.S. taxation could materially affect our financial position and results of operations.

It is possible that various states or foreign countries may regulate our transmissions or levy additional sales, income or other taxes relating to our activities. Tax authorities at the international, federal, state and local levels are currently reviewing the appropriate treatment of companies engaged in Internet commerce and marketplace operators, and new or revised international, federal, state or local tax regulations may subject us or our customers to additional sales, income and other taxes. We cannot predict the effect of current attempts to impose sales, income or other taxes on commerce over the Internet. New or revised taxes and, in particular, obligations on online marketplaces and remote sellers to collect sales taxes, VAT and similar taxes, including digital service taxes, may result in liability for third party obligations and would likely increase the cost of doing business online and decrease the attractiveness of advertising and selling goods and services over the Internet. For example, digital service taxes

adopted by certain countries or similar regulations could adversely affect our financial results. New taxes or the enactment of new tax laws could also create significant increases in internal costs necessary to capture data, and collect and remit taxes. Any of these events could have an adverse effect on our business and results of operations.

On December 22, 2017, new legislation was signed into law that revises the Internal Revenue Code of 1986, as amended. The newly enacted federal income tax law contained significant changes to corporate taxation. As a result of recent changes in the US Administration, it is likely that further US federal tax law changes will be introduced. The details of proposed changes are still to be confirmed. While these changes will likely impact Groupon's worldwide effective tax rate, it is difficult to determine the extent of the impact until further details of the proposed changed are issued.

Federal laws and regulations, such as the Bank Secrecy Act and the USA PATRIOT Act and similar foreign laws, could be expanded to include Groupon vouchers or other offerings.

Various federal laws, such as the Bank Secrecy Act and the USA PATRIOT Act and foreign laws and regulations, such as the European Directive on the prevention of the use of the financial system for the purpose of money laundering and terrorist financing, impose certain anti-money laundering requirements on companies that are financial institutions or that provide financial products and services. For these purposes, financial institutions are broadly defined to include money services businesses such as money transmitters, check cashers and sellers or issuers of stored value cards. Examples of anti-money laundering requirements imposed on financial institutions include subscriber identification and verification programs, record retention policies and procedures and transaction reporting. We do not believe that we are a financial institution subject to these laws and regulations based, in part, upon the characteristics of Groupon vouchers and our role with respect to the distribution of Groupon vouchers to customers. For example, the Financial Crimes Enforcement Network ("FinCEN"), a division of the U.S. Treasury Department tasked with implementing the requirements of the Bank Secrecy Act (the "BSA"), has adopted regulations expanding the scope of the BSA and requirements for parties involved in stored value or prepaid access cards, including a proposed expansion of financial institutions to include sellers or issuers of prepaid access cards. While we believe Groupon vouchers are not subject to these regulations, it is possible that FinCEN or a court of law could consider Groupon vouchers (or other Groupon products) a financial product and thus deem Groupon to be subject to such laws and obligations as a financial institution. In the event that we become subject to the requirements of the Bank Secrecy Act or any other anti-money laundering law or regulation imposing obligations on us as a money services business, our regulatory compliance costs to meet these obligations would likely increase which could adversely impact our operating results.

State and foreign laws regulating money transmission could be expanded to include Groupon vouchers or other Groupon products or services.

Many states and certain foreign jurisdictions impose license and registration obligations on those companies engaged in the business of money transmission, with varying definitions of what constitutes money transmission. We currently believe that we are not a money transmitter given our role and the product terms of Groupon vouchers or other Groupon products or services. However, a successful challenge to our position or expansion of state or foreign laws could subject us to increased compliance costs and delay our ability to offer Groupon vouchers or other products or services in certain jurisdictions pending receipt of any necessary licenses or registrations.

Risks Related to Our Capital Structure

Our access to capital and ability to raise capital in the future may be limited, which could prevent us from growing, and our existing credit agreement could restrict our business activities.

We may need additional capital in the future and to seek additional financing or covenant relief. Any such financing may not be available on acceptable terms, or at all, and our failure to raise capital when needed could harm our business. We have outstanding $250.0 million in aggregate principal amount of 3.25% convertible senior notes (the "Notes"). In addition, we are party to a $225.0 million amended and restated credit agreement with JPMorgan Chase Bank, N.A., as administrative agent, dated as of May 14, 2019, as amended (the "Amended Credit Agreement"), which matures in May 2024. In particular, the Notes (as defined below) mature in April 2022. If we don’t redeem or refinance the Notes at least 91 days prior to their maturity, the maturity date of our Amended Credit Agreement will spring forward to January 2022, subject to certain exceptions. We continue to evaluate our long-term capital structure.

The Amended Credit Agreement contains financial and other covenants that may restrict our business activities or our ability to execute our strategic objectives. Due to the impact of COVID-19 on our business, we entered into an amendment to the Amended Credit Agreement in July 2020 to provide, among other things, covenant relief through the first quarter of 2021, and we may need to seek additional relief in the future depending on the timing and volatility of the recovery of our business from COVID-19. Failure to comply with the covenants contained in our Amended Credit Agreement (if not waived or further amended) could give rise to an event of default and, if not cured, entitle the lenders to accelerate the indebtedness outstanding thereunder and terminate our ability to borrow in the future under the Amended Credit Agreement. Further, acceleration of indebtedness under the Amended Credit Agreement could result in an event of default under the indenture (the "Indenture") governing our 3.25% convertible notes (the "Notes"). Any termination of our ability to borrow or event of default under our Amended Credit Agreement would have a material adverse impact on our liquidity.

Additionally, other general economic conditions and our future operating performance, could ultimately limit our access to funding under our Amended Credit Agreement. Furthermore, additional equity financing may dilute the interests of our common stockholders, and debt financing, if available, may involve restrictive covenants that could further restrict our business activities or our ability to execute our strategic objectives and could reduce our profitability. If we cannot access the full capacity of our credit facility or raise or borrow funds on acceptable terms or at all, it could adversely affect our liquidity, and we may not be able to grow our business or respond to competitive pressures.

We may not have the ability to use cash to settle the principal amount of our Notes upon conversion or to repurchase the Notes upon a fundamental change, which could result in dilution and could adversely affect our financial condition.

The Notes are convertible any time prior to their maturity on April 1, 2022 into cash, stock or a combination of cash and stock at an initial conversion rate set forth in the Indenture. Notes that are converted in connection with a make-whole fundamental change (as defined in the Indenture) may be entitled to an increase in the conversation rate for such Notes. Upon a conversion event, if we do not have adequate cash available or cannot obtain additional financing, or our use of cash is restricted by applicable law, regulations or agreements governing our current or future indebtedness, we may not be able to use cash to settle the principal amount of the Notes upon conversion. If we settle any portion of the principal amount of the Notes upon conversion in stock, it will result in immediate dilution to the ownership interests of existing stockholders and such dilution could be material.

In addition, holders of the Notes have the right to require us to repurchase their Notes upon the occurrence of a fundamental change (as defined in the Indenture) at a repurchase price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest, if any. If we do not have adequate cash available or cannot obtain additional financing, or our use of cash is restricted by applicable law, regulations or agreements governing our current or future indebtedness, we may not be able repurchase the Notes when required under the Indenture, which would constitute an event of default under the Indenture. An event of default under the Indenture could also lead to a default under other agreements governing our current and future indebtedness, and if the repayment of such other indebtedness were accelerated, we may not have sufficient funds to repay the indebtedness and repurchase the Notes or make cash payments upon conversion of the Notes.

The terms of the Notes could delay or prevent an attempt to take over our Company.

The terms of the Notes require us to repurchase the Notes in the event of a fundamental change. A takeover of our Company would constitute a fundamental change. This could have the effect of delaying or preventing a takeover of our Company that may otherwise be beneficial to our stockholders.

Risks Related to Ownership of Our Common Stock

The trading price of our common stock is highly volatile.

The trading price of our common stock has fluctuated significantly since our initial listing on NASDAQ. We expect that the trading price of our stock will continue to be volatile due to variations in our operating results and also may change in response to other factors, including factors specific to technology and Internet commerce companies, many of which are beyond our control. Among the factors that could affect our stock price are:

•our financial results;

•any financial projections that we provide to the public, any changes in these projections or our failure for any reason to meet these projections or projections made by research analysts;

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

•the relative success of competitive products or services;

•the public's response to press releases or other public announcements by us or others, including our filings with the SEC and announcements relating to litigation;

•the impact of COVID-19 on our business;

•speculation about our business in the press or the investment community;

•future sales of our common stock by our significant stockholders, officers and directors;

•announcements about our share repurchase program and purchases under the program;

•changes in our capital structure, such as any refinancing or future issuances of debt or equity securities;

•our entry into new markets or exits from existing markets;

•regulatory developments;

•strategic acquisitions, joint ventures or restructurings announced or consummated by us or our competitors;

•strategic dispositions of businesses or other assets announced or consummated by us;

•our ability to execute our strategy; and

•changes in accounting principles.

We expect the stock price volatility to continue for the foreseeable future as a result of these and other factors.

If securities or industry analysts do not publish research or reports about our business, or publish inaccurate or unfavorable research reports about our business, our share price and trading volume could decline.

The trading market for our common stock depends, in part, on the research and reports that securities or industry analysts publish about us or our business. We do not have any control over these analysts, and in the past, we have had changes in analyst ratings that have affected our stock price. If one or more of the analysts who cover us should downgrade our shares or change their opinion of our shares, industry sector or products, our share price would likely decline. If one or more of these analysts ceases coverage of our company or fails to regularly publish reports on us, we could lose visibility in the financial markets, which could cause our share price or trading volume to decline.

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

We intend to retain all of our earnings for the foreseeable future to finance the operation and expansion of our business and do not anticipate paying cash dividends. As a result, stockholders can expect to receive a return on their investment in our common stock only if the market price of the stock increases.

Provisions in our charter documents and under Delaware law could discourage a takeover that stockholders may consider favorable.

Provisions in our certificate of incorporation and bylaws may have the effect of delaying or preventing a change of control or changes in our management. These provisions include the following:

•Our Board of Directors has the right to elect directors to fill a vacancy created by the expansion of the Board of Directors or the resignation, death or removal of a director, which prevents stockholders from being able to fill vacancies on our Board of Directors.

•Special meetings of our stockholders may be called only by our Chairman of the Board of Directors, our Chief Executive Officer, our Board of Directors or holders of not less than the majority of our

issued and outstanding common stock. This limits the ability of minority stockholders to take certain actions without an annual meeting of stockholders.

•Our stockholders may not act by written consent unless the action to be effected and the taking of such action by written consent is approved in advance by our Board of Directors. As a result, a holder, or holders, controlling a majority of our common stock would generally not be able to take certain actions without holding a stockholders' meeting.

•Our certificate of incorporation prohibits cumulative voting in the election of directors. This limits the ability of minority stockholders to elect director candidates.

•Stockholders must provide timely notice to nominate individuals for election to the Board of Directors or to propose matters that can be acted upon at an annual meeting of stockholders. These provisions may discourage or deter a potential acquiror from conducting a solicitation of proxies to elect the acquiror's own slate of directors or otherwise attempting to obtain control of our company.

•Our Board of Directors may issue, without stockholder approval, shares of undesignated preferred stock. The ability to authorize undesignated preferred stock makes it possible for our Board of Directors to issue preferred stock with voting or other rights or preferences that could impede the success of any attempt to acquire us.

The convertible note hedge and warrant transactions may affect the value of our common stock.

On May 9, 2016, we purchased convertible note hedges from certain bank counterparties. The convertible note hedges are intended to reduce the potential economic dilution upon conversion of the Notes. On May 9, 2016, we also sold warrants to certain bank counterparties. The warrant transactions would separately have a dilutive effect to the extent that the market price per share of our common stock exceeds the applicable strike price of the warrants.

The bank counterparties or their respective affiliates may modify their initial hedge positions by entering into or unwinding various derivatives contracts with respect to our common stock and/or purchasing or selling our common stock or other securities of ours in secondary market transactions prior to the maturity of the Notes (and are likely to do so during any observation period related to a conversion of Notes or following any repurchase of Notes by us on any fundamental change repurchase date or otherwise). This activity could cause or avoid a significant change in the market price of our common stock.

In addition, in some circumstances, such as an early termination of the convertible note hedge and warrant transactions, including in connection with certain change of control transactions or other extraordinary events, the bank counterparties or their respective affiliates may unwind their hedge positions with respect to our common stock, which could adversely affect the value of our common stock.

PART II

ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

Our common stock has been listed on the NASDAQ Global Select Market under the symbol "GRPN" since November 4, 2011.

Reverse Stock Split

In June 2020, we effectuated a reverse stock split of our shares of common stock at a ratio of 1-for-20 and a corresponding reduction in the number of authorized shares of our common stock. On the effective date, every 20 shares of issued and outstanding common stock were combined and converted into one issued and outstanding share of common stock. The number of authorized shares of Common Stock was reduced proportionately. Fractional shares were cancelled and stockholders received cash in lieu thereof and the par value per share of common stock remains unchanged. A proportionate adjustment was also made to the maximum number of shares of common stock issuable under the Groupon, Inc. Stock Plans (the "Plans"), and the Groupon, Inc. 2012 Employee Stock Purchase Plan, as amended ("ESPP").

As a result, the number of shares and income (loss) per share disclosed throughout this Annual Report on Form 10-K have been retrospectively adjusted to reflect the reverse stock split.

Holders

As of February 22, 2021, there were 104 holders of record of our common stock. Each holder of our common stock is entitled to one vote per share on any matter that is submitted to a vote of stockholders.

Recent Sales of Unregistered Securities

During the year ended December 31, 2020, we did not issue any unregistered equity securities.

Issuer Purchases of Equity Securities

In May 2018, the Board authorized us to repurchase up to $300.0 million of our common stock under our share repurchase program. During the year ended December 31, 2020, we did not purchase any shares under the repurchase program. As of December 31, 2020, up to $245.0 million of common stock remained available for purchase under our program.The timing and amount of share repurchases, if any, will be determined based on market conditions, limitations under the Amended Credit Agreement, share price, available cash and other factors, and the share repurchase program may be terminated at any time. We will fund the repurchases, if any, through cash on hand, future cash flows and borrowings under our credit facility. Repurchases will be made in compliance with SEC rules and other legal requirements and may be made in part under a Rule 10b5-1 plan, which permits stock repurchases when we might otherwise be precluded from doing so. See Item 8, Note 13, Stockholders' Equity, for information regarding our share repurchase program.

Since the inception of our share repurchase programs in August 2013 through December 31, 2020, we have repurchased 10,294,117 shares of our common stock (or Class A common stock prior to the conversion of our Class A common stock and Class B common stock to a single class of common stock on October 31, 2016) for an aggregate purchase price of $922.7 million (including fees and commissions).

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations should be read together with our consolidated financial statements and related notes included under Item 8 of this Annual Report on Form 10-K. This discussion contains forward-looking statements about our business and operations. Our actual results may differ materially from those we currently anticipate as a result of many factors, including those we describe under Item 1A, Risk Factors, and elsewhere in this Annual Report. See Part I, Forward-Looking Statements, for additional information.

Overview

Currently, we generate product and service revenue from the following business operations.

In 2020, the COVID-19 pandemic has led to significant disruption in our business. See Strategy, Restructuring and Cost Reduction and Factors Affecting our Performance below, and Item 8, Note 3, COVID-19 Pandemic, for more information about the impacts of COVID-19 on our business.

Strategy

In February 2020, we announced a strategic plan to focus on our local experiences marketplace, which included exiting our Goods category. However, due to the significant disruption in our business due to the COVID-19 pandemic we continue to sell Goods on our platform. In the third quarter 2020, we announced an updated strategy and plan to prioritize expanding our Local inventory and modernizing our marketplace by improving the merchant and customer experiences. While both of these are important to building a successful marketplace, we believe the most critical of these is expanding Local inventory.

To validate our strategic priority of expanding Local inventory, early in the third quarter 2020 we launched a test in four markets in North America to determine if growing inventory would result in improved billings and units performance. To grow Local supply, we focused on leveraging three types of inventory: Deals with few restrictions, new, lower discount Offers, and Market Rate supply. At the conclusion of our test in December 2020, we determined that we reached our test goals and we intend to scale elements of our inventory strategy more broadly throughout our marketplace in 2021. We also intend to continue to make enhancements to the customer and merchant experiences in 2021.

Restructuring and Cost Reduction

During the year ended December 31, 2020 we took significant actions to improve our cash position and materially reduce our cost structure. In April 2020, the Board approved a multi-phase restructuring plan related to our previously announced strategic shift and as part of the cost cutting measures implemented in response to the impact of COVID-19 on our business.

The first phase of our restructuring actions included an overall reduction of approximately 1,200 positions globally and the exit or discontinuation of the use of certain leases and other assets by the end of 2020. The majority of the first phase of workforce reductions and impairments of our right-of-use and other long-lived assets occurred during the second quarter 2020. In the third quarter 2020, we initiated the second phase of our restructuring plan, which included additional workforce reductions and the exit of our operations in New Zealand and Japan. We expect to incur total pre-tax charges of $75.0 million to $105.0 million in connection with our multi-phase restructuring plan through the end of 2021. Once fully implemented, we expect our multi-phase restructuring plan to result in $225.0 million in annualized cost savings. During the year ended December 31, 2020, we recorded $64.8 million in pre-tax charges in connection with our restructuring actions. See Item 8, Note 16, Restructuring and Related Charges, for more information.

In addition to the actions described above, we took several steps to reduce costs, preserve cash in the near-term and improve liquidity, including, but not limited to: furloughing staff; continuing to sell Goods on our platform instead of quickly exiting the category; reducing marketing expense by significantly shortening payback thresholds and delaying brand marketing investments; transitioning merchants to redemption payment terms, instead of fixed payment terms; implementing a hiring freeze; eliminating broad-based merit increases for employees; replacing cash compensation with equity compensation in 2020 for Board members; and amending our Credit Agreement to, among other things, provide covenant relief through the first quarter of 2021. See Liquidity and Capital Resources for further information.

How We Measure Our Business

We use several operating and financial metrics to assess the performance of our business and make decisions on where to allocate capital, time and technology investments. Certain of the financial metrics are reported in accordance with U.S. generally accepted accounting principles ("GAAP") and certain of those metrics are considered non-GAAP financial measures. As our business evolves, we may make changes to the key financial and operating metrics that we use to measure our business. For further information and reconciliations to the most applicable financial measures under U.S. GAAP, refer to our discussion under Non-GAAP Financial Measures in the Results of Operations section.

Operating Metrics

•Gross billings is the total dollar value of customer purchases of goods and services. Gross billings is presented net of customer refunds, order discounts and sales and related taxes. The substantial majority of our service revenue transactions are comprised of sales of vouchers and similar transactions in which we collect the transaction price from the customer and remit a portion of the transaction price to the third-party merchant who will provide the related goods or services. For these transactions, gross billings differs from revenue reported in our consolidated statements of operations, which is presented net of the merchant's share of the transaction price. For product revenue transactions, gross billings are equivalent to product revenue reported in our consolidated statements of operations. Gross billings is an indicator of our growth and business performance as it measures the dollar volume of transactions generated through our marketplaces. Tracking gross billings on service revenue transactions also allows us to monitor the percentage of gross billings that we are able to retain after payments to merchants. However, we are focused on achieving long-term gross profit and Adjusted EBITDA growth.

•Active customers are unique user accounts that have made a purchase during the trailing twelve months ("TTM") either through one of our online marketplaces or directly with a merchant for which we earned a commission. We consider this metric to be an important indicator of our business performance as it helps us to understand how the number of customers actively purchasing our offerings is trending. Some customers could establish and make purchases from more than one account, so it is possible that our active customer metric may count certain customers more than once in a given period. For entities that we have acquired in a business combination, this metric includes active customers of the acquired entity, including customers who made purchases prior to the acquisition. We do not include consumers who solely make purchases

with retailers using digital coupons accessed through our websites and mobile applications in our active customer metric, nor do we include consumers who solely make purchases of our inventory through third-party marketplaces with which we partner.

•Units are the number of purchases during the reporting period, before refunds and cancellations, made either through one of our online marketplaces, a third-party marketplace, or directly with a merchant for which we earn a commission. We do not include purchases with retailers using digital coupons accessed through our websites and mobile applications in our units metric. We consider units to be an important indicator of the total volume of business conducted through our marketplaces.

Our gross billings, units and TTM active customers for the years ended December 31, 2020, 2019 and 2018 were as follows (in thousands):


	Year Ended December 31,

Financial Metrics

•Revenue is currently earned through product and service revenue transactions. We earn service revenue from transactions in which we generate commissions by selling goods or services on behalf of third-party merchants. Service revenue from those transactions is reported on a net basis as the purchase price collected from the customer for the offering less an agreed upon portion of the purchase price paid to the third-party merchant. Service revenue also includes commissions we earn when customers make purchases with retailers using digital coupons accessed through our digital properties. We generate product revenue from our sales of first-party Goods inventory. Our product revenue from these first-party transactions, which are direct sales of merchandise inventory, is the purchase price received from the customer. We have transitioned to a third-party marketplace in North America as of the end of 2020 and will begin to transition in International in the second quarter 2021. Following the International transition, we expect our Goods category to primarily generate revenue on a net basis within service revenue.

•Gross profit reflects the net margin we earn after deducting our cost of revenue from our revenue. Due to the lack of comparability between product revenue, which is reported on a gross basis, and service revenue, which primarily consists of transactions reported on a net basis, we believe that gross profit is an important measure for evaluating our performance.

•Adjusted EBITDA is a non-GAAP financial measure that we define as net income (loss) from continuing operations excluding income taxes, interest and other non-operating items, depreciation and amortization, stock-based compensation, acquisition-related expense (benefit), net and other special charges and credits, including items that are unusual in nature or infrequently occurring. For further information and a reconciliation to Income (loss) from continuing operations, refer to our discussion under Non-GAAP Financial Measures in the Results of Operations section.

•Free cash flow is a non-GAAP financial measure that comprises net cash provided by (used in) operating activities from continuing operations less purchases of property and equipment and capitalized software. For further information and a reconciliation to Net cash provided by (used in) operating activities from continuing operations, refer to our discussion in the Liquidity and Capital Resources section.

The following table presents the above financial metrics for the years ended December 31, 2020, 2019 and 2018 (in thousands):

Operating Expenses

•Marketing expense consists primarily of online marketing costs, such as search engine marketing, advertising on social networking sites and affiliate programs, and offline marketing costs, such as television and radio advertising. Additionally, compensation expense for marketing employees is classified within marketing expense. We record these costs within Marketing on the consolidated statements of operations when incurred. From time to time, we have offerings from well-known national merchants for customer acquisition and activation purposes, for which the amount we owe the merchant for each voucher sold exceeds the transaction price paid by the customer. Our gross billings from those transactions generate no service revenue and our net cost (i.e., the excess of the amount owed to the merchant over the amount paid by the customer) is classified as marketing expense. We evaluate marketing expense as a percentage of gross profit because it gives us an indication of how well our marketing spend is driving gross profit performance.

•Selling, general and administrative ("SG&A") expenses include selling expenses such as sales commissions and other compensation expenses for sales representatives, as well as costs associated with supporting the sales function such as technology, telecommunications and travel. General and administrative expenses include compensation expense for employees involved in customer service, operations, technology and product development, as well as general corporate functions, such as finance, legal and human resources. Additional costs included in general and administrative include depreciation and amortization, rent, professional fees, litigation costs, travel and entertainment, recruiting, office supplies, maintenance, certain technology costs and other general corporate costs. We evaluate SG&A expense as a percentage of gross profit because it gives us an indication of our operating efficiency.

•Restructuring and related charges represent severance and benefit costs for workforce reductions, impairments and other facilities-related costs and professional advisory fees. See Item 8, Note 16, Restructuring and Related Charges, for information about our restructuring plan.

Factors Affecting Our Performance

Impact of COVID-19. During the COVID-19 pandemic, various government restrictions and changes in consumer behavior have had a negative impact on our business, which relies on customers' purchases of local experiences, including events and activities, beauty and wellness, travel and dining. Recovery from the COVID-19 pandemic could be volatile and prolonged given the unprecedented and continuously evolving nature of the situation. We continue to monitor the impact of COVID-19 on our business. See Item 8, Note 3, COVID-19 Pandemic, for more information about the impacts of COVID-19 on our business and Item 1A, Risk Factors.

Attracting and retaining local merchants. As we focus on our local experiences marketplace, we depend on our ability to attract and retain merchants who are willing to offer their experiences on our platform. Merchants can generally withdraw their offerings from our marketplace at any time, and their willingness to continue offering services through our marketplace depends on the effectiveness of our marketing and promotional services. Since the widespread economic impacts of COVID-19 began in March 2020, we are prioritizing opportunities to help drive demand for our merchants and highlighting offers that customers can enjoy right now. As we continue to navigate through the volatility of the COVID-19 recovery period, we intend to take a market-by-market approach to attracting and retaining local merchants.

Driving purchase frequency and re-engaging and retaining customers. In light of significant declines in consumer demand for local and travel services due to COVID-19, we must highlight offers that customers can enjoy right now in order to drive purchase frequency and retain customers. This includes surfacing the relevant Local inventory in each market depending on the government restrictions currently in place and continuing to leverage our Goods category in the near-term. We must also continue to improve the customer experience on our websites and mobile applications, launch innovative products that remove friction from the customer journey and drive awareness to our supply, and grow our high-quality, bookable inventory.

Increasing traffic to our websites and mobile applications. The traffic to our websites and mobile applications, including from consumers responding to our emails and search engine optimization ("SEO"), has declined in recent years, and we have experienced further declines in traffic due to the impacts of COVID-19. As such, we must focus on improving the effectiveness of our emails, as well as developing sources of traffic in addition to email and SEO and optimizing the efficiency of our marketing spend.

Comparison of the Years Ended December 31, 2020 and 2019:

North America revenue and gross profit decreased by $540.3 million and $332.1 million, for the year ended December 31, 2020. Those declines were primarily driven by a decline in gross billings and transaction volume due to the impacts of COVID-19. Revenue also declined due to the ongoing transition of our Goods category to a third-party marketplace model. In a third-party marketplace model, we generate service revenue which is presented on a net basis. The increase in service margin was due to a shift in mix of offerings sold and higher variable consideration from unredeemed vouchers due to our shift towards payment on redemption terms in North America.

North America cost of revenue decreased by $208.2 million for the year ended December 31, 2020 primarily due to the decrease in transaction volume and gross billings and the impacts of the ongoing transition of our Goods category to a third-party marketplace model.

Comparison of the Years Ended December 31, 2019 and 2018:

North America revenue and gross profit decreased by $280.5 million and $82.9 million for the year ended December 31, 2019. Those declines were primarily driven by a decline in transaction volume due to fewer customers and lower customer traffic, including traffic from email and SEO, as discussed above.

The decrease in gross profit was partially offset by a $197.5 million decline in cost of revenue, which was primarily due to the decrease in transaction volume and gross billings.

Marketing and Contribution Profit

We define contribution profit as gross profit less marketing expense. North America contribution profit for the years ended December 31, 2020, 2019 and 2018 was as follows (dollars in thousands):

Contribution Profit	$	379,592		$	593,676		$	616,897		(36.1)	%	(3.8)	%

Comparison of the Years Ended December 31, 2020 and 2019:

North America marketing expense and marketing expense as a percentage of gross profit declined for the year ended December 31, 2020 due to accelerated traffic declines, significantly shortened payback thresholds and lower investment in our offline marketing and brand spend in light of COVID-19.

The decline in our North America contribution profit for the year ended December 31, 2020 was primarily attributable to a $332.1 million decrease in gross profit, as discussed above, partially offset by a $118.0 million decrease in marketing.

Comparison of the Years Ended December 31, 2019 and 2018:

North America marketing expense and marketing expense as a percentage of gross profit declined for the year ended December 31, 2019 as compared with the prior year as we leveraged improved marketing analytics to drive efficiency in our marketing spend and maximize the lifetime value of our customer base.

The decline in our North America Contribution profit for the year ended December 31, 2019 was primarily attributable to a $82.9 million decrease in gross profit, as discussed above, partially offset by a $59.7 million decrease in marketing.

For the year ended December 31, 2020 International gross billings declined by $634.0 million, units declined by 17.9 million and active customers decreased by 5.0 million. Those decreases were primarily due to the significant decrease in consumer demand due to changes in consumer behavior and actions taken by governments to control the spread of COVID-19, including quarantines, travel restrictions, as well as business restrictions and shutdowns. The decline in gross billings was partially offset by a $11.9 million favorable impact from year-over-year changes in foreign currency exchange rates.

Comparison of the Years Ended December 31, 2019 and 2018:

For the year ended December 31, 2019 International gross billings declined by $152.2 million, units declined by 2.1 million and active customers decreased by 0.5 million. Those decreases were primarily due to weak consumer sentiment in Europe, especially in the United Kingdom, and intense competition in our Goods business. The decline in gross billings was also driven by an $83.1 million unfavorable impact from year-over-year changes in foreign currency exchange rates.

Comparison of the Years Ended December 31, 2020 and 2019:

International revenue and gross profit decreased by $261.8 million and $176.7 million for the year ended December 31, 2020. Those decreases were primarily driven by a decline in gross billings due to the impacts of COVID-19 as discussed above. The decreases in revenue and gross profit were partially offset by favorable impacts of $9.5 million and $3.2 million from year-over-year changes in foreign currency exchange rates.

Cost of revenue decreased by $85.0 million for the year ended December 31, 2020 primarily due to the decrease in transaction volume and gross billings and a $6.3 million unfavorable impact from year-over-year changes in foreign currency exchange rates.

The decrease in gross profit was also driven by a customer shift toward lower margin offerings.

The decline in gross profit was partially offset by a decrease in cost of revenue of $85.8 million, which was primarily due to the decline in gross billings, as discussed above, a shift in our Goods category mix from product revenue transactions, which are reported on a gross basis, toward service revenue transactions, which are reported on a net basis, and a $26.0 million favorable impact from year-over-year changes in foreign currency exchange rates.

Marketing expense and marketing expense as a percentage of gross profit declined for the year ended December 31, 2020 due to accelerated traffic declines, significantly shortened payback thresholds and lower investment in our offline marketing and brand spend in light of COVID-19.

SG&A decreased for the year ended December 31, 2020 primarily due to lower payroll-related expenses due to furloughs and restructuring actions. SG&A as a percentage of gross profit increased for the year ended December 31, 2020 due to the decline in demand and traffic as a result of COVID-19.

During the first quarter 2020, we performed an interim quantitative impairment assessment of goodwill and long-lived assets as a result of significant deterioration in our financial performance due to the impact of COVID-19. As a result, we recognized goodwill impairment of $109.5 million, that represented the excess of the EMEA reporting unit's carrying value over its fair value, and long-lived asset impairment of $22.4 million for the year ended December 31, 2020. See Item 8, Note 3, COVID-19 Pandemic, for additional information about goodwill and long-lived asset impairments.

Restructuring and related charges increased for the year ended December 31, 2020 related to severance and benefit costs for workforce reductions, impairments and other facilities-related charges, and professional advisory fees resulting from our restructuring activities. See Item 8, Note 16, Restructuring and Related Charges, for more information.

Comparison of the Years ended December 31, 2019 and 2018:

Marketing expense and marketing expense as a percentage of gross profit for the year ended December 31, 2019 decreased as we leveraged marketing analytics to drive efficiency in our marketing spend and maximize the lifetime value of our customer base and decreased our offline marketing spend during the year.

SG&A decreased for the year ended December 31, 2019 primarily due to the absence of expense related to our patent litigation with IBM of $34.6 million recorded in 2018, lower facilities and payroll-related expenses and a $16.6 million favorable impact from year-over-year changes in foreign currency exchange rates.

Other Income (Expense), Net

Other income (expense), net includes interest income, interest expense, gains and losses on fair value option investments, adjustments for observable price changes of investments, impairments of investments and foreign currency gains and losses, primarily resulting from intercompany balances with our subsidiaries that are denominated in foreign currencies.

Other income (expense), net for the years ended December 31, 2020, 2019 and 2018 was as follows (dollars in thousands):


	Year Ended December 31,
	2020		2019		2018
Interest income	$	6,351	$	7,744	$	6,420
Interest expense	(33,192)		(23,593)		(21,909)
Changes in fair value of investments	(1,405)		(72,497)		(9,064)
Foreign currency gains (losses), net	17,919		(5,960)		(20,325)
Impairments of investments	(6,684)		(9,961)		(10,156)
Upward adjustment for observable price changes of investment	—		51,397		—
Other	43		(459)		2,026
Other income (expense), net	$	(16,968)	$	(53,329)	$	(53,008)

Comparison of the Years Ended December 31, 2020, 2019, and 2018:

The change in Other income (expense), net for the year ended December 31, 2020 as compared with the prior year is primarily related to a $71.1 million decrease in losses from changes in fair value of investments, and a $23.9 million increase in foreign currency gains (losses), net, partially offset by a decrease in unrealized gain of $51.4 million as a result of an upward adjustment for observable price changes on an other equity investment.

The change in Other income (expense), net for the year ended December 31, 2019 as compared with the prior year was primarily related to $69.4 million loss from changes in fair value of our investment in Monster LP, partially offset by an unrealized gain of $51.4 million as a result of an upward adjustment for observable price changes on an other equity investment. See Item 8, Note 8, Investments, for additional information. The change in Other income (expense) was partially offset by a $14.4 million decrease in foreign currency losses for the year ended December 31, 2019. Foreign currency gains (losses) primarily result from intercompany balances with our subsidiaries that are denominated in foreign currencies.

Provision (Benefit) for Income Taxes

Comparison of the Years Ended December 31, 2020, 2019, and 2018:

Provision (benefit) for income taxes for the years ended December 31, 2020, 2019 and 2018 was as follows (dollars in thousands):


	Year Ended December 31,									% Change
	2020			2019			2018			2020 vs 2019		2019 vs 2018
Provision (benefit) for income taxes	$	(7,504)		$	761		$	(957)		1,086.1	%	179.5	%
Effective tax rate	2.6		%	(5.6)		%	(92.8)		%

Our U.S. Federal income tax rate was 21% for the years ended December 31, 2020, 2019 and 2018. The primary factor impacting the effective tax rate for the years ended December 31, 2020, 2019 and 2018 was the pretax losses incurred in jurisdictions that have valuation allowances against their net deferred tax assets. We expect that our consolidated effective tax rate in future periods will continue to differ significantly from the U.S. federal income tax rate as a result of our tax obligations in jurisdictions with profits and valuation allowances in jurisdictions with losses. See Item 8, Note 17, Income Taxes, for additional information relating to tax audits and assessments and regulatory and legal developments that may impact our business and results of operations in the future.

The effective tax rate for the years ended December 31, 2020 and 2019 also reflected the reversal of reserves for uncertain tax positions due to the closure of tax audits and due to the closure of applicable statutes of limitation. The year ended December 31, 2020 was also impacted by the carryback of federal net operating losses due to the income tax relief provided by the Coronavirus Aid, Relief, and Economic Security Act ("CARES Act"). The effective tax rate for year ended December 31, 2018 also reflected a $6.4 million income tax benefit resulting from the impact of adopting Topic 606 on intercompany activity in certain foreign jurisdictions.

Income (Loss) from Discontinued Operations

In connection with a strategic initiative to optimize our global footprint, we sold or ceased our operations in 12 countries between November 2016 and March 2017. The financial results of those operations have been presented as discontinued operations in the consolidated financial statements.

Non-GAAP Financial Measures

In addition to financial results reported in accordance with U.S. GAAP, we have provided the following non-GAAP financial measures: Adjusted EBITDA, free cash flow and foreign currency exchange rate neutral operating results. Those non-GAAP financial measures, which are presented on a continuing operations basis, are intended to aid investors in better understanding our current financial performance and prospects for the future as seen through the eyes of management. We believe that those non-GAAP financial measures facilitate comparisons with our historical results and with the results of peer companies who present similar measures (although other companies may define non-GAAP measures differently than we define them, even when similar terms are used to identify such measures). However, those non-GAAP financial measures are not intended to be a substitute for those reported in accordance with U.S. GAAP.

Adjusted EBITDA. Adjusted EBITDA is a non-GAAP performance measure that we define as net income (loss) from continuing operations excluding income taxes, interest and other non-operating items, depreciation and amortization, stock-based compensation, acquisition-related expense (benefit), net and other special charges and credits, including items that are unusual in nature or infrequently occurring. Our definition of Adjusted EBITDA may differ from similar measures used by other companies, even when similar terms are used to identify such measures. Adjusted EBITDA is a key measure used by our management and Board of Directors to evaluate operating performance, generate future operating plans and make strategic decisions for the allocation of capital. Accordingly, we believe that Adjusted EBITDA provides useful information to investors and others in understanding and evaluating our operating results in the same manner as our management and Board of Directors. However, Adjusted EBITDA is not intended to be a substitute for income (loss) from continuing operations.

We exclude stock-based compensation expense and depreciation and amortization because they are primarily non-cash in nature and we believe that non-GAAP financial measures excluding those items provide meaningful supplemental information about our operating performance and liquidity. Acquisition-related expense (benefit), net is comprised of the change in the fair value of contingent consideration arrangements and external transaction costs related to business combinations, primarily consisting of legal and advisory fees. The composition of our contingent consideration arrangements and the impact of those arrangements on our operating results vary over time based on a number of factors, including the terms of our business combinations and the timing of those transactions. For the year ended December 31, 2020, special charges and credits also included charges related to our restructuring plan, goodwill and long-lived asset impairments and strategic advisor costs. For the year ended December 31, 2018, special charges and credits also included a charge related to our patent litigation with IBM. We exclude special charges and credits from Adjusted EBITDA because we believe that excluding those items provides meaningful supplemental information about our core operating performance and facilitates comparisons with our historical results.

The following is a reconciliation of Adjusted EBITDA to the most comparable U.S. GAAP financial measure, Income (loss) from continuing operations for the years ended December 31, 2020, 2019, and 2018 (dollars in thousands):


	Year Ended December 31,

(1)Restructuring and related charges includes $21.6 million of long-lived asset impairments and $1.7 million of additional stock compensation for the year ended December 31, 2020.

Free cash flow. Free cash flow is a non-GAAP liquidity measure that comprises net cash provided by operating activities from continuing operations less purchases of property and equipment and capitalized software. We use free cash flow to conduct and evaluate our business because, although it is similar to cash flow from continuing operations, we believe that it typically represents a more useful measure of cash flows because purchases of fixed assets, software developed for internal use and website development costs are necessary components of our ongoing operations. Free cash flow is not intended to represent the total increase or decrease in our cash balance for the applicable period.

Free cash flow has limitations due to the fact that it does not represent the residual cash flow available for discretionary expenditures. For example, free cash flow does not include cash payments for business acquisitions. In addition, free cash flow reflects the impact of the timing difference between when we are paid by customers and when we pay merchants and suppliers. Therefore, we believe it is important to view free cash flow as a complement to our entire consolidated statements of cash flows. For a reconciliation of free cash flow to the most comparable U.S. GAAP financial measure, see Liquidity and Capital Resources below.

Foreign currency exchange rate neutral operating results. Foreign currency exchange rate neutral operating results show current period operating results as if foreign currency exchange rates had remained the same as those in effect in the prior year period. Those measures are intended to facilitate comparisons to our historical performance.

The following table represents the effect on our consolidated statements of operations from changes in exchange rates versus the U.S. dollar for the years ended December 31, 2020 and 2019 (in thousands):

Liquidity and Capital Resources

Our principal sources of liquidity are cash flows from operations and cash balances, which primarily consist of bank deposits and government money market funds. As of December 31, 2020, cash balances, including outstanding borrowings under our Amended Credit Agreement, were $850.6 million.

Our net cash flows from operating, investing and financing activities from continuing operations for the years ended December 31, 2020, 2019 and 2018 were as follows (in thousands):


	Year Ended December 31,
	2020		2019		2018
Cash provided by (used in):
Operating activities	$	(63,598)	$	71,283	$	190,855
Investing activities	(21,346)		(67,591)		(135,982)
Financing activities	$	176,798	$	(92,619)	$	(84,417)

Free cash flow is a non-GAAP liquidity measure that comprises net cash provided by operating activities from continuing operations, less purchases of property and equipment and capitalized software from continuing operations. Our free cash flow for the years ended December 31, 2020, 2019 and 2018 and reconciliations to the most comparable U.S. GAAP financial measure, Net cash provided by (used in) operating activities from continuing operations, for those periods are as follows (in thousands):


	Year Ended December 31,
	2020		2019		2018
Net cash provided by (used in) operating activities from continuing operations	$	(63,598)	$	71,283	$	190,855
Purchases of property and equipment and capitalized software from continuing operations	(48,711)		(67,328)		(69,695)
Free cash flow	$	(112,309)	$	3,955	$	121,160

Our revenue-generating transactions are primarily structured such that we collect cash up-front from customers and pay third-party merchants at a later date, either upon the customer's redemption of the related voucher or fixed payment terms, which are generally biweekly, throughout the term of the merchant's offering. Historically, we have primarily paid merchants on fixed payment terms in North America and upon voucher redemption internationally. In prior periods, we began to increase our use of redemption payment terms with our North America merchants, and we accelerated this transition in 2020 to improve liquidity as our business was impacted by COVID-19. We largely completed the transition to redemption payment terms in the third quarter 2020.

Our cash balances fluctuate significantly throughout the year based on many variables, including gross billings growth rates, the timing of payments to merchants and suppliers, seasonality and the mix of transactions between Goods and Local.

For the year ended December 31, 2020, our net cash used in operating activities from continuing operations was $63.6 million, as compared with our $286.6 million loss from continuing operations. That difference was primarily attributable to $295.6 million of non-cash items, including $109.5 million of goodwill impairment, $22.4 million of long-lived asset impairments, $21.6 million of restructuring-related impairments, depreciation and amortization and stock-based compensation, partially offset by a $72.6 million net decrease from changes in working capital and other assets and liabilities. The working capital decrease was due to the impacts of COVID-19, partially offset by the transition to a third-party goods marketplace in North America.

For the year ended December 31, 2019, our net cash provided by operating activities from continuing operations was $71.3 million, as compared with our $14.3 million loss from continuing operations. That difference was primarily attributable to $230.2 million of non-cash items, including depreciation and amortization, stock-based compensation, a $69.4 million loss from changes in fair value of our investment in Monster LP and a $51.4 million upward adjustment to another equity investment for observable price changes in an orderly transaction. The difference between our net cash provided by operating activities and our income from continuing operations due to non-cash items was, partially offset by a $145.0 million net decrease from changes in working capital and other assets and liabilities. The working capital impact was primarily related to the decline of billings, and to a lesser extent seasonal timing of payments to inventory suppliers.

For the year ended December 31, 2018, our net cash provided by operating activities from continuing operations was $190.9 million, as compared with our $2.0 million income from continuing operations. That difference was primarily attributable to $206.8 million of non-cash items, including depreciation and amortization, and stock-based compensation. The difference between net cash provided by operating activities and our income from continuing operations due to non-cash items was partially offset by a $17.9 million net decrease from changes in working capital and other assets and liabilities. The working capital impact was primarily related to the seasonal timing of payments to inventory suppliers and also includes $42.1 million of the payment to IBM related to the settlement of our patent litigation.

Our net cash used in investing activities from continuing operations was $21.3 million, $67.6 million and $136.0 million for the years ended December 31, 2020, 2019 and 2018. For the year ended December 31, 2020, our net cash used in investing activities from continuing operations included purchases of property and equipment and capitalized software of $48.7 million, which was partially offset by proceeds from the sale of an investment of $31.6 million. For the year ended December 31, 2019, our net cash used in investing activities from continuing operations included purchases of property and equipment and capitalized software of $67.3 million. For the year ended December 31, 2018, our net cash used in investing activities from continuing operations included net cash paid for a business acquisition of $58.1 million, purchases of property and equipment and capitalized software of $69.7 million and net cash paid of $18.3 million for acquisitions of intangible assets, including $15.4 million related to the settlement of our IBM patent litigation.

Our net cash provided by financing activities was $176.8 million for the year ended December 31, 2020. Our net cash used in financing activities was $92.6 million and $84.4 million for the years ended December 31 2019 and 2018. For the year ended December 31, 2020, net cash provided by financing activities included $200.0 million of borrowings under our revolving credit facility, partially offset by $10.6 million in taxes paid related to net share settlements of stock-based compensation awards and $8.9 million in payments of finance lease obligations. For the year ended December 31, 2019, net cash used in financing activities included $45.6 million in repurchases of common stock under our share repurchase program, $19.7 million in payments of finance lease obligations and $18.1 million in taxes paid related to net share settlements of stock-based compensation awards. For the year ended December 31, 2018, net cash used in financing activities included $33.0 million in payments of finance lease obligations, $24.1 million in taxes paid related to net share settlements of stock-based compensation awards, $9.6 million in repurchases of common stock under our share repurchase program and an $8.4 million payment of a financing obligation related to a business acquisition.

In April 2016, we issued convertible notes with an aggregate principal amount of $250.0 million, due April 2022. We received net proceeds of $243.2 million from the issuance of the Notes. We have used the proceeds from the Notes for general corporate purposes, including repurchases of shares of our common stock. Additionally, we entered into note hedge and warrant transactions with certain bank counterparties that are designed to offset, in

part, the potential dilution from conversion of the Notes. See Item 8, Note 10, Financing Arrangements, for additional information.

The amendment to the revolving credit agreement (the "Amendment" and the revolving credit agreement as amended, the "Amended Credit Agreement") provides for aggregate principal borrowings of up to $225.0 million. As of December 31, 2020, we had $200.0 million of borrowings and $20.6 million of letters of credit outstanding under the Amended Credit Agreement and were in compliance with all covenants.

In July 2020, we entered into an amendment of our Credit Agreement in order to, among other things, provide us operational flexibility and covenant relief through the end of the first quarter 2021 in light of the ongoing impacts of COVID-19 on our business. We may need to seek additional covenant relief in the future depending on the timing and volatility of the recovery of our business from COVID-19. In addition, the Amended Credit Agreement matures in May 2024. If we do not redeem or refinance the Notes at least 91 days prior to their maturity, the maturity date of our Amended Credit Agreement will spring forward to January 2022, subject to certain exceptions. We continue to evaluate our long-term capital structure, and may need to seek additional financing in the future. See Item 1, Risk Factors and Item 8, Note 10, Financing Arrangements, for additional information.

We believe that our cash balances, excluding borrowings under the Amended Credit Agreement, and cash generated from operations will be sufficient to meet our working capital requirements and capital expenditures for at least the next 12 months. We plan to continue to actively manage and optimize our cash balances and liquidity, working capital and operating expenses, although there can be no assurances that we will be able to do so. In 2020, we took several steps to reduce costs and preserve cash in the near-term as described in Item 8, Note 3, COVID-19 Pandemic.

As of December 31, 2020, we had $267.5 million in cash held by our international subsidiaries, which is primarily denominated in Euros, British Pounds Sterling, Canadian dollars, and, to a lesser extent, Australian dollars and Japanese yen. In general, it is our practice and intention to re-invest the earnings of our non-U.S. subsidiaries in those operations. We have not, nor do we anticipate the need to, repatriate funds to the United States to satisfy domestic liquidity needs arising in the ordinary course of business.

In May 2018, the Board of Directors authorized us to repurchase up to $300.0 million of our common stock under our share repurchase program. As of December 31, 2020, up to $245.0 million of common stock remained available for purchase under our program. The timing and amount of share repurchases, if any, will be determined based on market conditions, limitations under the Amended Credit Agreement, share price, available cash and other factors, and the program may be terminated at any time. Repurchases will be made in compliance with SEC rules and other legal requirements and may be made, in part, under a Rule 10b5-1 plan, which permits share repurchases when we might otherwise be precluded from doing so.

Contractual Obligations and Commitments

The following table summarizes (in thousands) our future contractual obligations and commitments as of December 31, 2020. The table below excludes $25.6 million of non-current liabilities for unrecognized tax benefits, including interest and penalties, as of December 31, 2020. We cannot make a reasonable estimate of the period of cash settlement for the tax positions classified as non-current liabilities.

(1)Finance lease obligations include both principal and interest components of future minimum finance lease payments.

(2)Operating lease obligations are primarily for office facilities and are noncancelable. Certain leases contain periodic rent escalation adjustments and renewal and expansion options. Operating lease obligations expire at various dates with the latest maturity in 2027.

(3)Represents the principal amount and related interest on our convertible senior notes.

(4)Purchase obligations primarily represent noncancelable contractual obligations related to cloud computing and other information technology services.

Off-Balance Sheet Arrangements

We did not have any off-balance sheet arrangements as of December 31, 2020.

Critical Accounting Policies and Estimates

Management's Discussion and Analysis of Financial Condition and Results of Operations is based upon our consolidated financial statements, which have been prepared in accordance with U.S. GAAP. Our significant accounting policies are discussed in Item 8, Note 2, Summary of Significant Accounting Policies, in the notes to the consolidated financial statements.

The preparation of consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts and classifications of assets and liabilities, revenue and expenses, and related disclosure of contingent liabilities. Management bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from those estimates under different assumptions or conditions.

We believe that the estimates and assumptions related to revenue recognition, lease recognition and measurement, impairment assessments of goodwill and long-lived assets, income taxes and fair value option investments have the greatest potential impact on our consolidated financial statements. Therefore, we consider these to be our critical accounting policies and estimates.

Revenue Recognition

See Item 8, Note 2, Summary of Significant Accounting Policies and Item 8, Note 15, Revenue Recognition, for information about our revenue recognition accounting policies, including estimates of our refund liabilities and estimates of variable consideration from unredeemed vouchers.

Leases

See Item 8, Note 2, Summary of Significant Accounting Policies for information about our lease recognition and measurement accounting policies.

Impairment Assessments of Goodwill and Long-Lived Assets

See Item 8, Note 2, Summary of Significant Accounting Policies for information about our accounting policies relating to impairment of goodwill and long-lived assets. Additional information about those accounting policies and estimates is set forth in the following paragraphs.

When determining fair values in impairment tests, we use one of the following recognized valuation methods: the income approach (including discounted cash flows), the market approach and the cost approach. Our significant estimates in those fair value measurements include identifying business factors such as size, growth, profitability, risk and return on investment and assessing comparable revenue and earnings multiples. Further, when measuring fair value based on discounted cash flows, we make assumptions about risk-adjusted discount rates; rates of increase in revenue, cost of revenue and operating expenses; weighted average cost of capital; rates of long-term growth; and income tax rates. Valuations are performed by management or third-party valuation specialists under management's supervision, where appropriate. We believe that the estimated fair values used in impairment tests are based on reasonable assumptions that marketplace participants would use. However, such assumptions are inherently uncertain and actual results could differ from those estimates.

During the first quarter 2020, we determined a triggering event occurred that required us to evaluate our goodwill and long-lived assets for impairment, and we recorded impairment charges as a result of that assessment. During the third quarter 2020, we exited our operations in Japan and New Zealand, which represents the majority of the countries in our Asia Pacific reporting unit. As a result, we combined the remainder of the Asia Pacific reporting unit and the EMEA reporting unit into a single International reporting unit, consistent with how management reviews the operating results of the business. Our two reporting units as of our October 1, 2020 annual goodwill impairment test were North America and International.

Future changes in our assumptions or the interrelationship of the assumptions described above may negatively impact future valuations. In future measurements of fair value, adverse changes in assumptions could result in impairments of goodwill or long-lived assets that would require non-cash charges to the consolidated statements of operations and may have a material effect on our financial condition and operating results.

Income Taxes

See Item 8, Note 2, Summary of Significant Accounting Policies, and Note 17, Income Taxes, for information about our income tax accounting policies.

Fair Value Option Investments

See Item 8, Note 8, Investments, for information about the fair value measurements of our fair value option investments.

Estimating the fair values of our investments requires significant judgment regarding the assumptions that market participants would use in pricing those assets. As the fair value measurements involve significant unobservable inputs, such as cash flow projections and discount rates, they are classified as Level 3 within the fair value hierarchy. Future changes in judgment about the related fair value inputs, including changes that may result from any subsequent financing transactions undertaken by those investees, could result in significant increases or decreases in fair value that would be recognized in earnings. Our election to apply fair value accounting to those investments has and may continue to cause fluctuations in our earnings from period to period.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We have operations both within the United States and internationally, and we are exposed to market risks in the ordinary course of our business, including the effect of foreign currency fluctuations, interest rate changes and inflation. Information relating to quantitative and qualitative disclosures about these market risks is set forth below.

Foreign Currency Exchange Risk

We transact business in various foreign currencies other than the U.S. dollar, principally the euro, British pound sterling, Canadian dollar and Australian dollar, which exposes us to foreign currency risk. For the year ended December 31, 2020, we derived approximately 42.2% of our revenue from our International segment. Revenue and related expenses generated from our international operations are generally denominated in the local currencies of the corresponding countries. The functional currencies of our subsidiaries that either operate or support these markets are generally the same as the corresponding local currencies. However, the results of operations of, and certain of our intercompany balances associated with, our international operations are exposed to foreign currency exchange rate fluctuations. Upon consolidation, as exchange rates vary, our revenue and other operating results may differ materially from expectations, and we may record significant gains or losses on the re-measurement of intercompany balances.

We assess our foreign currency exchange risk based on hypothetical changes in rates utilizing a sensitivity analysis that measures the potential impact on working capital based on a 10% change (increase and decrease) in currency rates. We use a current market pricing model to assess the changes in the value of the U.S. dollar on foreign currency denominated monetary assets and liabilities. The primary assumption used in this model is a hypothetical 10% weakening or strengthening of the U.S. dollar against those currency exposures as of December 31, 2020 and 2019.

As of December 31, 2020, our net working capital surplus (defined as current assets less current liabilities) from subsidiaries that are subject to foreign currency translation risk was $11.4 million. The potential increase in this working capital surplus from a hypothetical 10% adverse change in quoted foreign currency exchange rates would be $1.1 million. This compares to a $69.2 million working capital deficit subject to foreign currency exposure as of December 31, 2019, for which a 10% adverse change would have resulted in a potential increase in this working capital deficit of $6.9 million.

Interest Rate Risk

Our cash balance as of December 31, 2020 consists of bank deposits and government money market funds, so exposure to market risk for changes in interest rates is limited. In April 2016, we issued convertible notes with an aggregate principal amount of $250.0 million (see Item 8, Note 10, Financing Arrangements). The convertible notes bear interest at a fixed rate, so we have no financial statement impact from changes in interest rates. However, changes in market interest rates impact the fair value of the convertible notes along with other variables such as our credit spreads and the market price and volatility of our common stock. In June 2020, we entered into the Amended Credit Agreement which provides for aggregate principal borrowings of up to $225.0 million. As of December 31, 2020, we had $200.0 million of borrowings outstanding and $20.6 million of outstanding letters of credit under the Amended Credit Agreement. See Item 7, Liquidity and Capital Resources, for additional information. Because borrowings under the Amended Credit Agreement bear interest at a variable rate, we are exposed to market risk relating to changes in interest rates if we borrow under the Amended Credit Agreement. We also have $129.4 million of lease obligations as of December 31, 2020. Interest rates on existing leases typically do not change unless there is a modification to a lease agreement and as such, we do not believe that the interest rate risk on the lease obligations is significant.

Impact of Inflation

We believe that our results of operations are not materially impacted by moderate changes in the inflation rate. Inflation and changing prices did not have a material effect on our business, financial condition or results of operations for the year ended December 31, 2020.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the stockholders and the Board of Directors of Groupon, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Groupon, Inc. and subsidiaries (the “Company”) as of December 31, 2020 and 2019, the related consolidated statements of operations, comprehensive income (loss), stockholders’ equity, and cash flows, for each of the three years in the period ended December 31, 2020, and the related notes and the schedule listed in the Index at Item 15(2) (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 25, 2021, expressed an unqualified opinion on the Company’s internal control over financial reporting.

Change in Accounting Principle

As discussed in Notes 2 and 11 to the financial statements, the Company has changed its method of accounting for leases in 2019 due to the adoption of the guidance in ASC Topic 842, Leases, using the modified retrospective method.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current-period audit of the financial statements that were communicated or required to be communicated to the audit committee and that (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Income Taxes—Foreign Tax Position—Refer to Notes 2 and 17 to the financial statements

Critical Audit Matter Description

The Company received a proposed income tax assessment from the tax authority in one foreign jurisdiction in the amount of $126.4 million, inclusive of estimated incremental interest from the original assessment. The Company believes the assessment, which primarily relates to transfer pricing on transactions occurring during 2011, is without merit and it intends to vigorously defend itself.

Given the complexity of the relevant tax laws and regulations, auditing management’s evaluation and accounting for the tax position associated with the foreign income tax assessment involved especially subjective and complex judgments.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the accounting for the tax position associated with the foreign income tax assessment included the following, among others:

•We tested the effectiveness of controls over income taxes, including those over accounting for uncertain tax positions.

•With the assistance of our foreign and US income tax specialists, we evaluated management’s analysis regarding the likelihood of sustaining its foreign tax position upon examination by the relevant foreign tax authorities; and, we evaluated management’s estimate of the amount of tax benefit recognized.

•We assessed the basis of the Company’s analysis and measurement by:

◦Obtaining, reading, and evaluating the outside legal opinion received by the Company supporting its foreign tax position

◦Obtaining, reading, and evaluating the written response from the outside legal counsel representing the Company provided to us as part of our annual legal inquiry process

◦Obtaining, reading, and evaluating management’s written analysis supporting the accounting position

◦Making direct inquiries of the outside legal counsel representing the Company in this proposed assessment by the foreign tax authority

◦Evaluating any developments in the matter during the current fiscal year through inquiry of Company personnel and their outside legal counsel.

Goodwill—Refer to Notes 2, 3, and 7 to the financial statements

Critical Audit Matter Description

The Company’s annual and periodic evaluations of goodwill impairment involve the comparison of the fair value of each of the Company’s reporting units to its carrying value. The Company determines the fair value of its reporting units using the income approach (including discounted cash flows). With respect to the income approach, management makes significant estimates and assumptions related to forecasts of future performance, including revenues, cost of revenue, and operating expenses and risk-adjusted discount rates. The goodwill balance subject to the impairment test was $214.7 million as of December 31, 2020. The Company recorded goodwill impairment charges of $109.5 million for the year ended December 31, 2020.

Auditing the estimates and assumptions that impacted the valuation of the reporting units involved especially subjective judgment, specifically related to the forecasts of revenues and cost of revenue and operating expenses and selection of risk-adjusted discount rates.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the Company’s forecasts of revenues, cost of revenue, and operating expenses and its selection of risk-adjusted discount rates included the following, among others:

•We tested the effectiveness of controls over the annual and periodic goodwill impairment assessment, including those over the forecasts.

•We evaluated management’s ability to reliably forecast by comparing actual results to management’s historical forecasts.

•We evaluated the reasonableness of management’s forecasts by comparing the forecasts to (1) historical results and previous forecasts, (2) internal communications to management and the Board of Directors, (3) macroeconomic forecasts, and (4) forecasts utilized in other areas of the audit to evaluate consistency, where appropriate. Additionally, we obtained and evaluated management’s written analysis supporting the forecasted cash flows.

•With the assistance of fair value specialists, we evaluated the reasonableness of the 1) valuation methodology and 2) risk-adjusted discount rates by:

◦Evaluating whether the fair value models being used are appropriate considering the Company’s circumstances and valuation premise identified

◦Testing the source information and the mathematical accuracy of the calculation underlying the determination of the risk-adjusted discount rates, and developing a range of independent estimates and comparing those to the risk-adjusted discount rates selected by management.

Long-Lived Assets—Refer to Notes 2, 3 and 6 to the financial statements

Critical Audit Matter Description

The Company determined the significant deterioration in its financial performance due to the disruption in its operations from COVID-19 and the sustained decrease in its stock price required evaluation of its long-lived assets for impairment, which resulted in a $22.4 million impairment of its long-lived assets for the year ended December 31, 2020. The Company determines the fair value of its asset groups using the income approach (including discounted cash flows). With respect to the income approach, management makes significant estimates and assumptions related to forecasts of future performance, including revenue, cost of revenue, and operating expenses and risk-adjusted discount rates.

Auditing the estimates and assumptions that impacted the valuation of the asset groups involved especially subjective judgment, specifically related to the forecasts of revenues, cost of revenue, and operating expenses and selection of risk-adjusted discount rates.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the Company’s forecasts of revenues, cost of revenue, and operating expenses and its selection of risk-adjusted discount rates included the following, among others:

•We tested the effectiveness of controls over the long-lived asset impairment assessment, including those over the forecasts.

•We evaluated management’s ability to reliably forecast by comparing actual results to management’s historical forecasts.

•With the assistance of fair value specialists, we evaluated the reasonableness of the risk-adjusted discount rate by testing the source information and the mathematical accuracy of the calculation and developing a range of independent estimates and comparing those to the risk-adjusted discount rates selected by management.

1. DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION

Company Information

Groupon, Inc. and subsidiaries, which commenced operations in October 2008, is a global scaled two-sided marketplace that connects consumers to merchants by offering goods and services, generally at a discount. Consumers access our marketplace through our mobile applications and our websites, primarily localized groupon.com sites in many countries.

Our operations are organized into two segments: North America and International. See Note 21, Segment Information

COVID-19 Pandemic

For the year ended December 31, 2020, the COVID-19 pandemic has had an adverse impact on our financial condition, results of operations and cash flow, including the impairment of our long-lived assets and goodwill. See Note 3, COVID-19 Pandemic, for more information.

Reverse Stock Split

In June 2020, we effectuated a reverse stock split of our shares of common stock at a ratio of 1-for-20. See Note 13, Stockholders' Equity, for additional information. As a result, the number of shares and income (loss) per share disclosed throughout this Annual Report on Form 10-K have been retrospectively adjusted to reflect the reverse stock split.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation

The consolidated financial statements include the accounts of Groupon, Inc. and its subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The consolidated financial statements were prepared in accordance with U.S. GAAP and include the assets, liabilities, revenue and expenses of all wholly-owned subsidiaries and majority-owned subsidiaries over which we exercise control and variable interest entities for which we have determined that we are the primary beneficiary. Outside stockholders' interests in subsidiaries are shown on the consolidated financial statements as Noncontrolling interests. Investments in entities in which we do not have a controlling financial interest are accounted for at fair value, as available-for-sale securities or at cost adjusted for observable price changes and impairments, as appropriate.

Adoption of New Accounting Standards

We adopted the guidance in ASU 2016-13, Financial Instruments - Credit Losses (Topic 326) - Measurement of Credit Losses of Financial Instruments ("CECL"), on January 1, 2020. This ASU requires entities to measure credit losses for financial assets measured at amortized cost based on expected losses over the lifetime of the asset rather than incurred losses. The adoption of ASU 2016-13 did not have a material impact on the consolidated financial statements.

We adopted the guidance in ASU 2017-04, Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment, on January 1, 2020. This ASU eliminates Step 2 of the goodwill impairment test and requires a goodwill impairment to be measured as the amount by which a reporting unit's carrying amount exceeds its fair value, not to exceed the carrying amount of its goodwill. During the first quarter 2020, we determined a triggering event occurred that required us to evaluate our goodwill for impairment, and we recorded an impairment charge as a result of that assessment. See Note 3, COVID-19 Pandemic, for additional information.

We adopted the guidance in ASU 2018-13, Fair Value Measurement (Topic 820) - Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurements, on January 1, 2020. This ASU modifies the disclosure requirements in Topic 820, Fair Value Measurements by removing, modifying, or adding certain disclosures. The adoption of ASU 2018-13 did not have a material impact on the consolidated financial statements.

GROUPON, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

We adopted the guidance in ASU 2016-02, Leases (Topic 842), on January 1, 2019. This ASU requires the recognition of lease assets and liabilities for operating leases, in addition to the finance lease assets and liabilities historically recorded on our consolidated balance sheets. We adopted Topic 842 using the modified retrospective transition method. Beginning on January 1, 2019, our consolidated financial statements are presented in accordance with the revised policies, while prior period amounts are not adjusted and continue to be reported in accordance with our historical policies. For additional information on the impact of adoption of Topic 842 on our accounting policies, refer to our discussion under Lease and Asset Retirement Obligations below.

The modified retrospective transition method required the cumulative effect, if any, of initially applying the guidance to be recognized as an adjustment to our accumulated deficit as of our adoption date. As a result of adopting Topic 842, we recognized additional lease assets and liabilities of $109.6 million as of January 1, 2019. The discount rate used to calculate that adjustment was the rate implicit in the lease, unless that rate was not readily determinable. For leases for which the rate was not readily determinable, the discount rate used was our incremental borrowing rate as of the adoption date, January 1, 2019. There was no cumulative effect adjustment to our accumulated deficit as a result of initially applying the guidance. Aside from the impact to our consolidated balance sheet discussed above, lease accounting policies and presentation within the consolidated statement of operations and consolidated statements of cash flows is substantially consistent with historical treatment.

We elected the package of practical expedients permitted under the transition guidance within Topic 842, which allowed us to carry forward prior conclusions about lease identification, classification and initial direct costs for leases entered into prior to adoption of Topic 842. Additionally, we elected to not separate lease and non-lease components for all of our leases. For leases with a term of 12 months or less, we elected the short-term lease exemption, which allowed us to not recognize right-of-use assets or lease liabilities for qualifying leases existing at transition and new leases we may enter into in the future.

We adopted the guidance in ASU 2018-07, Compensation - Stock Compensation (Topic 718) - Improvements to Nonemployee Share-Based Payment Accounting, on January 1, 2019. This ASU expands the scope to make the guidance for share-based payment awards to nonemployees consistent with the guidance for share-based payment awards to employees. The adoption of ASU 2018-07 did not have a material impact on the consolidated financial statements.

We adopted the guidance in ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40) - Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, on January 1, 2019. This ASU requires entities in a hosting arrangement that is a service contract to follow the guidance in Subtopic 350-40, Internal-Use Software, to determine which costs to implement the service contract would be capitalized as an asset related to the service contract and which costs would be expensed. The requirements of ASU 2018-15 have been applied on a prospective basis to implementation costs incurred on or after January 1, 2019. As a result of the adoption of ASU 2018-15, we capitalized $10.5 million and $7.4 million of implementation costs for the years ended December 31, 2020 and 2019. We recognized $1.7 million of amortization related to these implementation costs for the year ended December 31, 2020. We did not recognize any amortization related to these implementation costs for the year ended December 31, 2019.

GROUPON, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

We adopted the guidance in ASC Topic 606, Revenue from Contracts with Customers, on January 1, 2018. Topic 606 is a comprehensive new revenue recognition model that requires a company to recognize revenue to depict the transfer of goods or services to a customer at an amount that reflects the consideration it expects to receive in exchange for those goods or services. We adopted Topic 606 using the modified retrospective method. Beginning on January 1, 2018, results are presented in accordance with the revised policies. The adoption of Topic 606 did not significantly impact our presentation of revenue on a gross or net basis. For additional information on the impact of adoption of Topic 606 on our accounting policies, refer to our discussion under Revenue Recognition below.

We recorded a net reduction to our opening accumulated deficit of $88.9 million, which is net of a $6.7 million income tax effect, as of January 1, 2018 due to the cumulative impact of adopting Topic 606. The following table summarizes balance sheet accounts impacted by the cumulative effect of adopting Topic 606 (in thousands):


	Increase (decrease) to beginning accumulated deficit
Prepaid expenses and other current assets	$	(4,007)
Other non-current assets	(10,223)
Accrued merchant and supplier payables	(64,970)
Accrued expenses and other current liabilities	(13,188)
Other non-current liabilities	3,443
Effect on beginning accumulated deficit	$	(88,945)

We adopted the guidance in ASU 2016-01, Financial Instruments (Topic 825-10) - Recognition and Measurement of Financial Assets and Financial Liabilities, as amended, on January 1, 2018. This ASU generally requires equity investments to be measured at fair value with changes in fair value recognized through net income and eliminates the cost method for equity securities. However, for equity investments without readily determinable fair values, the ASU permits entities to elect to measure the investments at cost adjusted for observable price changes and impairments, with changes in the measurement recognized through net income. We applied that measurement alternative to our equity investments that were previously accounted for under the cost method. The adoption of ASU 2016-01 did not have a material impact on the consolidated financial statements.

We adopted the guidance in ASU 2016-18, Statement of Cash Flows (Topic 230) - Restricted Cash, on January 1, 2018. This ASU requires companies to include amounts generally described as restricted cash and restricted cash equivalents, along with cash and cash equivalents, when reconciling the beginning-of-period and end-of-period amounts shown on the consolidated statements of cash flows. Previously, changes in restricted cash were reported within cash flows from operating activities.

We adopted the guidance in ASU 2017-05, Other Income-Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20) - Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets, on January 1, 2018. This ASU is meant to clarify the scope of ASC Subtopic 610-20, Other Income-Gains and Losses from the Derecognition of Nonfinancial Assets, and to add guidance for partial sales of nonfinancial assets. The adoption of ASU 2017-05 did not have a material impact on the consolidated financial statements.

We adopted the guidance in ASU 2017-07, Compensation - Retirement Benefits (Topic 715) - Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, on January 1, 2018. This ASU requires employers to include only the service cost component of net periodic pension cost in operating expenses, together with other employee compensation costs. The other components of net periodic pension cost, including interest cost, expected return on plan assets, amortization of prior service cost and settlement and curtailment effects, are to be included in non-operating expenses. The adoption of ASU 2017-07 did not have a material impact on the consolidated financial statements.

We adopted the guidance in ASU 2017-09, Compensation - Stock Compensation (Topic 718) - Scope of Modification Accounting, on January 1, 2018. This ASU clarifies the changes to terms or conditions of a share-based payment award that require an entity to apply modification accounting. The adoption of ASU 2017-09 did not have a material impact on the consolidated financial statements.

GROUPON, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

We adopted the guidance in ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220) - Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, as of January 1, 2018. This ASU permits a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act (the "Jobs Act"). As a result of the adoption of ASU 2018-02, we reclassified $0.2 million from accumulated other comprehensive income to accumulated deficit.

Reclassifications

Certain reclassifications have been made to the consolidated financial statements of prior periods and the accompanying notes to conform to the current period presentation.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Estimates in our consolidated financial statements include, but are not limited to, variable consideration from unredeemed vouchers; income taxes; leases; initial valuation and subsequent impairment testing of goodwill, other intangible assets and long-lived assets; investments; receivables; customer refunds and other reserves; contingent liabilities; and the useful lives of property, equipment and software and intangible assets. Actual results could differ materially from those estimates.

Cash, Cash Equivalents and Restricted Cash

We consider all highly liquid investments with an original maturity of three months or less from the date of purchase to be cash equivalents. Restricted cash represents amounts that we are unable to access for operational purposes. These amounts primarily relate to withholdings from employee paychecks under our employee stock purchase plan ("ESPP").

Accounts Receivable, Net

Accounts receivable primarily represents the net cash due from credit card and other payment processors and from merchants and performance marketing networks for commissions earned on consumer purchases. The carrying amount of receivables is reduced by an allowance for expected credit losses that reflects management's best estimate of amounts that will not be collected. We establish an allowance for expected credit losses on accounts receivable based on identifying the following customer risk characteristics: size, type of customer, and payment terms offered in the normal course of business. Receivables with similar risk characteristics are grouped into pools. For each pool, we consider the historical credit loss experience, current economic conditions, bankruptcy filings, published or estimated credit default rates, age of the receivable and any recoveries in assessing the lifetime expected credit losses.

Inventories

Inventories, consisting of merchandise purchased for resale, are accounted for using the first-in, first-out method of accounting and are valued at the lower of cost or net realizable value. We write down our inventory to the lower of cost or net realizable value based upon assumptions about future demand and market conditions. If actual market conditions are less favorable than those projected, additional inventory write-downs may be required. Once established, the original cost of the inventory less the related inventory write-down represents a new cost basis.

Property and Equipment

Property and equipment are stated at cost. Depreciation and amortization of property and equipment is recorded on a straight-line basis over the estimated useful lives of the assets. Generally, the useful lives are three to five years for computer hardware, office equipment and furniture and fixtures and the shorter of the term of the lease or five years for leasehold improvements and assets under finance leases.

GROUPON, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Internal-Use Software

We incur costs related to internal-use software and website development, including purchased software and internally-developed software. Costs incurred in the planning and evaluation stage of internally-developed software and website development are expensed as incurred. Costs incurred and accumulated during the application development stage are capitalized and included within Property, equipment and software, net on the consolidated balance sheets. Amortization of internal-use software is recorded on a straight-line basis over the two-year estimated useful life of the assets.

Cloud Computing Costs

We have entered into non-cancelable cloud computing hosting arrangements for which we incur implementation costs. Costs incurred in the planning and evaluation stage of the cloud computing hosting arrangement are expensed as incurred. Costs incurred during the application development stage related to implementation of the hosting arrangement are capitalized and included within Other current and non-current assets on the consolidated balance sheets. Amortization of implementation costs is recorded on a straight-line basis over the term of the associated hosting arrangement for each module or component of the related hosting arrangement when it is ready for its intended use. Amortization costs are recorded primarily in Selling, general and administrative expense on the consolidated statements of operations.

Goodwill

Goodwill is allocated to our reporting units at acquisition. Once goodwill has been allocated to the reporting units, it no longer retains its identification with a particular acquisition and becomes identified with the reporting unit in its entirety. Accordingly, the fair value of the reporting unit as a whole is available to support the recoverability of its goodwill.

We evaluate goodwill for impairment annually on October 1 or more frequently when an event occurs or circumstances change that indicates the carrying value may not be recoverable. We have the option to assess goodwill for impairment by first performing a qualitative assessment to determine whether it is more-likely-than-not that the fair value of a reporting unit is less than its carrying value. If it is determined that the reporting unit fair value is more-likely-than-not less than its carrying value, or if we do not elect the option to perform an initial qualitative assessment, we perform a quantitative assessment of the reporting unit's fair value. If the fair value of the reporting unit is in excess of its carrying value, the related goodwill is not impaired. If the fair value is less than the carrying value, we recognize an impairment equal to the difference between the carrying value of the reporting unit and its fair value, not to exceed the carrying value of goodwill. During the first quarter 2020, we determined a triggering event occurred that required us to evaluate our goodwill for impairment, and we recorded an impairment charge as a result of that assessment. During the third quarter 2020, we exited our operations in Japan and New Zealand, which represents the majority of the countries in our Asia Pacific reporting unit. As a result, we combined the remainder of the Asia Pacific reporting unit and the EMEA reporting unit into a single International reporting unit, consistent with how management reviews the operating results of the business. See Note 3, COVID-19 Pandemic, and Note 7, Goodwill and Other Intangible Assets, for more information.

Investments

Investments in equity shares without a readily determinable fair value and for which we do not have the ability to exercise significant influence are accounted for at cost adjusted for observable price changes and impairments, with changes in the measurement recognized through net income (loss). Those investments are classified within Investments on the consolidated balance sheets.

We have investments in common stock or in-substance common stock for which we have the ability to exercise significant influence and we have made an irrevocable election to account for those investments at fair value. Those investments are classified within Investments on the consolidated balance sheets.

Investments in convertible debt securities and convertible redeemable preferred shares are accounted for as available-for-sale securities, which are classified within Investments on the consolidated balance sheets. Available-for-sale securities are recorded at fair value each reporting period. Unrealized gains and losses, net of the related tax effects, are excluded from earnings and recorded as a separate component within Accumulated other

GROUPON, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

comprehensive income (loss) on the consolidated balance sheets until realized. Interest income from available-for-sale securities is reported within Other income (expense), net on the consolidated statements of operations.

Other-than-Temporary Impairment of Investments

We conduct reviews of our available-for-sale investments with unrealized losses on a quarterly basis to evaluate whether those impairments are other-than-temporary. Investments with unrealized losses that are determined to be other-than-temporary are written down to fair value with a charge to earnings. Unrealized losses that are determined to be temporary in nature are recorded, net of tax, in Accumulated other comprehensive income (loss) for available-for-sale securities.

Income Taxes

We account for income taxes using the asset and liability method, under which deferred income tax assets and liabilities are recognized based upon anticipated future tax consequences attributable to differences between the financial statement carrying amounts of assets and liabilities and their respective tax bases. We regularly review deferred tax assets to assess whether it is more likely than not that the deferred tax assets will be realized and, if necessary, establish a valuation allowance for portions of such assets to reduce the carrying value.

For purposes of assessing whether it is more likely than not that deferred tax assets will be realized, we consider the following four sources of taxable income for each tax jurisdiction: (a) future reversals of existing taxable temporary differences, (b) projected future earnings, (c) taxable income in carryback years, to the extent that carrybacks are permitted under the tax laws of the applicable jurisdiction, and (d) tax planning strategies, which represent prudent and feasible actions that a company ordinarily might not take, but would take to prevent an operating loss or tax credit carryforward from expiring unused. To the extent that evidence about one or more of these sources of taxable income is sufficient to support a conclusion that a valuation allowance is not necessary, other sources need not be considered. Otherwise, evidence about each of the sources of taxable income is considered in arriving at a conclusion about the need for and amount of a valuation allowance. See Note 17, Income Taxes, for further information about our valuation allowance assessments.

We are subject to taxation in the United States, various states and foreign jurisdictions. Significant judgment is required in determining the worldwide provision for income taxes and recording the related income tax assets and liabilities. During the ordinary course of business, there are many transactions and calculations for which the ultimate tax determination is uncertain. For example, our effective tax rate could be adversely affected by earnings being lower than anticipated in countries where it has lower statutory rates and higher than anticipated in countries where it has higher statutory rates, by changes in foreign currency exchange rates, by changes in the valuation of deferred tax assets and liabilities, by changes in the measurement of uncertain tax positions or by changes in the relevant laws, regulations, principles and interpretations. We account for uncertainty in income taxes by recognizing the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more-likely-than-not criteria, the amount recognized in the consolidated financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority.

Lease and Asset Retirement Obligations

We have entered into various non-cancelable operating lease agreements for our offices and data centers and non-cancelable finance lease agreements for property and equipment. Significant judgment is required when determining whether a contract is or contains a lease. We review contracts to determine whether the language conveys the right to control the use of an identified asset for a period of time in exchange for consideration.

We classify leases at their commencement as either operating or finance leases. We may receive renewal or expansion options, rent holidays, leasehold improvements or other incentives on certain lease agreements. We recognize a right-of-use asset and lease liability for all of our leases at the commencement of the lease. Lease liabilities are measured based on the present value of the minimum lease payments discounted by a rate determined as of the date of commencement. Right-of-use assets are measured based on the lease liability adjusted for any initial direct costs, prepaid rent, or lease incentives. Minimum lease payments made under operating and finance leases are apportioned between interest expense and a reduction of the related operating and finance lease obligations. Operating lease costs, including interest expense on operating leases, are presented

GROUPON, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

within Selling, general and administrative expense on the consolidated statements of operations and the related operating lease obligation is presented within Accrued expenses and other current liabilities and Operating lease obligations on the consolidated balance sheets. Amortization and interest expense on finance leases are presented within Selling, general and administrative expense and Other income (expense), net, respectively, on the consolidated statements of operations and the related finance lease obligation is presented within Accrued expenses and other current liabilities and Other non-current liabilities on the consolidated balance sheets.

As discussed above, the present value of minimum lease payments is used in determining the value of our operating and finance lease liabilities. The discount rate used to calculate the present value for lease payments is the rate implicit in the lease, unless that rate cannot be readily determined. For leases in which the rate implicit in the lease is not readily determinable, the discount rate is our incremental borrowing rate, which is determined based on information available at lease commencement and is equal to the rate of interest that we would have to pay to borrow on a collateralized basis over a similar term in an amount equal to the lease payments in a similar economic environment.

Certain lease agreements include variable lease costs which are primarily related to costs that are dependent on our usage of the underlying asset or lease payments that are dependent on an index when that index has changed since lease commencement. Those costs are expenses in the period in which they are incurred.

We establish liabilities for the present value of estimated future costs to retire long-lived assets at the termination or expiration of a lease. Those costs are capitalized and amortized over the lease term, and the recorded liabilities are accreted to the future value of the estimated retirement costs. The related amortization and accretion expenses are presented within Selling, general and administrative expense on the consolidated statements of operations.

We have also subleased certain office facilities under operating lease agreements, for which we recognize sublease income on a straight-line basis over their respective lease terms. Sublease income is generally presented within Selling, general and administrative expense on the consolidated statements of operations.

Revenue Recognition

We recognize revenue when we satisfy a performance obligation by transferring a promised good or service to a customer. Substantially all of our performance obligations are satisfied at a point in time rather than over time. We offer goods and services through our online marketplaces in three primary categories: Local, Goods and Travel.

Service revenue

Service revenue primarily represents the net commissions earned from selling goods or services on behalf of third-party merchants. Those transactions generally involve a customer's purchase of a voucher through one of our online marketplaces that can be redeemed by the customer with a third-party merchant for goods or services (or for discounts on goods or services). Service revenue from those transactions is reported on a net basis as the purchase price collected from the customer less the portion of the purchase price that is payable to the third-party merchant. We recognize revenue from those transactions when our commission has been earned, which occurs when a sale through one of our online marketplaces is completed and the related voucher has been made available to the customer. We believe that our remaining obligations to remit payment to the merchant and to provide information about vouchers sold are administrative activities that are immaterial in the context of the contract with the merchant. Revenue from hotel reservation offerings is recognized at the time the reservation is made, net of an allowance for estimated cancellations.

We also earn commissions when customers make purchases with retailers using digital coupons accessed through our websites and mobile applications. We recognize those commissions as revenue in the period in which the underlying transactions between the customer and the third-party merchant are completed. Additionally, we earn advertising revenue when the advertiser's logo or website link has been included on our websites or in specified email distributions for the requisite period of time as set forth in the agreement with the advertiser.

GROUPON, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Product revenue

We generate product revenue from our sales of first-party Goods transactions, which are direct sales of merchandise inventory. For product revenue transactions, we are the primary party responsible for providing the good to the customer, we have inventory risk and we have discretion in establishing prices. As such, product revenue is reported on a gross basis as the purchase price received from the customer. Product revenue, including associated shipping revenue, is recognized when title passes to the customer upon delivery of the product.

Variable Consideration for Unredeemed Vouchers

For merchant agreements with redemption payment terms, the merchant is not paid its share of the sale price for a voucher sold through one of our online marketplaces until the customer redeems the related voucher. If the customer does not redeem a voucher with such merchant payment terms, we retain all of the gross billings for that voucher, rather than retaining only our net commission. We estimate the variable consideration from vouchers that will not ultimately be redeemed using our historical voucher redemption experience at the time of sale. We apply a constraint to ensure it is probable that a significant reversal of revenue will not occur in future periods. In 2020, we have increased our constraint on revenue from unredeemed vouchers as customer redemptions have decreased due to the impacts of COVID-19 and may not be reflective of future redemption behavior. If actual redemptions differ from our estimates, the effects could be material to the consolidated financial statements.

Refunds

Refunds are recorded as a reduction of revenue. The liability for estimated refunds is included within Accrued expenses and other current liabilities on the consolidated balance sheets.

We estimate our refund reserve using historical refund experience by category. We assess the trends that could affect our estimates on an ongoing basis and make adjustments to the refund reserve calculations if it appears that changes in circumstances, including changes to our refund policies or general economic conditions, may cause future refunds to differ from our initial estimates. In 2020, we have experienced increased refund levels due to the impacts of COVID-19. If actual refunds differ from our estimates, the effects could be material to the consolidated financial statements.

Discounts, Customer Credits and Other Consideration Payable to Customers

We provide discount offers to encourage purchases of goods and services through our online marketplaces. We record discounts as a reduction of revenue.

Additionally, we issue credits to customers that can be applied to future purchases through our online marketplaces. Credits are primarily issued as consideration for refunds. To a lesser extent, credits are issued for customer relationship purposes. Credits issued to satisfy refund requests are applied as a reduction to the refund reserve and customer credits issued for relationship purposes are classified as a reduction of revenue. Breakage income from customer credits that are not expected to be used is estimated and recognized as revenue in proportion to the pattern of redemption for customer credits that are used.

Customer credits can be redeemed through our online marketplaces for goods or services provided by a third-party merchant or for merchandise inventory sold by us. When customer credits are redeemed for goods or services provided by a third-party merchant, service revenue is recognized on a net basis as the difference between the carrying amount of the customer credit liability derecognized and the amount due to the merchant for the related transaction. When customer credits are redeemed for merchandise inventory sold by us, product revenue is recognized on a gross basis equal to the amount of the customer credit liability derecognized. Historically, customer credits have primarily been used within one year of issuance; however, usage patterns have been impacted from changes in customer behavior due to COVID-19.

Sales and Related Taxes

Sales, use, value-added and related taxes that are imposed on specific revenue-generating transactions are presented on a net basis and excluded from revenue.

Costs of Obtaining Contracts

Incremental costs to obtain contracts with third-party merchants, such as sales commissions, are deferred and recognized on a straight-line basis over the expected period of the merchant arrangement, generally from 12 to 18 months. Those costs are classified within Selling, general and administrative expense in the consolidated statements of operations.

Cost of Revenue

Cost of revenue is comprised of direct and certain indirect costs incurred to generate revenue. Costs incurred to generate revenue, which include credit card processing fees, editorial costs, compensation expense for technology support personnel who are responsible for maintaining the infrastructure of our websites, amortization of internal-use software relating to customer-facing applications, web hosting and other processing fees are attributed to the cost of service and product revenue in proportion to gross billings during the period. For product revenue transactions, cost of revenue also includes the cost of inventory, shipping and fulfillment costs and inventory markdowns. Fulfillment costs are comprised of third-party logistics provider costs, as well as rent, depreciation, personnel costs and other costs of operating our fulfillment center.

Impairment of Long-Lived Assets

We review our long-lived assets, such as property, equipment and software, intangible assets and right-of-use assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. If circumstances require that a long-lived asset or asset group to be held and used be tested for possible impairment, we first compare the undiscounted cash flows expected to be generated by that long-lived asset or asset group to its carrying amount. If the carrying amount of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying amount exceeds its fair value.

Long-lived assets or disposal groups classified as held for sale are recorded at the lower of their carrying amount or fair value less estimated selling costs. Long-lived assets are not depreciated or amortized while classified as held for sale.

During the first quarter 2020, we determined a triggering event occurred that required us to evaluate our long-lived assets for impairment, and we recorded an impairment charge as a result of that assessment. See Note 3, COVID-19 Pandemic, for more information. During the year ended December 31, 2020, we recognized long-lived asset impairment charges related to our restructuring plan. See Note 16 Restructuring and Related Charges, for more information.

Stock-Based Compensation

We measure stock-based compensation cost at fair value. Expense is generally recognized on a straight-line basis over the service period during which awards are expected to vest, except for awards with both performance conditions and a graded vesting schedule, which are recognized using the accelerated method. We present stock-based compensation expense within the consolidated statements of operations based on the classification of the respective employees' cash compensation. See Note 14, Compensation Arrangements.

Foreign Currency

Balance sheet accounts of our operations outside of the United States are translated from foreign currencies into U.S. dollars at exchange rates as of the consolidated balance sheet dates. Revenue and expenses are translated at average exchange rates during the period. Foreign currency translation adjustments and foreign currency gains and losses on intercompany balances that are of a long-term investment nature are included within Accumulated other comprehensive income on the consolidated balance sheets. Foreign currency gains and losses resulting from transactions that are denominated in currencies other than the entity's functional currency, including foreign currency gains and losses on intercompany balances that are not of a long-term investment nature, are included within Other income (expense), net on the consolidated statements of operations.

Business Combinations

The results of businesses acquired are included in the consolidated financial statements beginning on the respective acquisition dates. The fair value of consideration transferred in business combinations is allocated to the tangible and intangible assets acquired and liabilities assumed at the acquisition date, with the remaining unallocated amount recorded as goodwill. Acquired goodwill represents the premium paid over the fair value of the net tangible and intangible assets acquired. We may pay a premium for a number of reasons, including growing our merchant base and acquiring an assembled workforce. The goodwill from business combinations is generally not deductible for tax purposes.

Recently Issued Accounting Standards

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740) - Simplifying the Accounting for Income Taxes. This ASU simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. The ASU will be effective for annual reporting periods beginning after December 15, 2020 and interim periods within those annual periods and early adoption is permitted. We believe that the adoption of this guidance will not have a material impact on our consolidated financial statements.

In March 2020, the FASB issued ASU 2020-03, Codification Improvements to Financial Instruments. This ASU amends a wide variety of Topics in the Codification, including revolving-debt arrangements and allowance for credit losses related to leases. This ASU will be effective for annual reporting periods beginning after December 15, 2020 and interim periods within those annual periods and early adoption is permitted. We believe that the adoption of this guidance will not have a material impact on our consolidated financial statements.

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. This ASU amends the guidance on convertible instruments and the derivatives scope exception for contracts in an entity's own equity, and also improves and amends the related EPS guidance for both Subtopics. This ASU will be effective for annual reporting periods beginning after December 15, 2021 and interim periods within those annual periods and early adoption is permitted. We believe the accounting for our convertible senior notes will be affected by ASU 2020-06, however, we are still assessing the impact on our consolidated financial statements.

In October 2020, the FASB issued ASU 2020-10, Codification Improvements. This ASU amends a variety of Topics, including presentation and disclosures of financial statements, interim reporting, accounting changes and error corrections. This ASU will be effective for annual reporting periods beginning after December 15, 2021 and interim periods within those annual periods beginning after December 15, 2022 and early adoption is permitted. We are still assessing the impact of ASU 2020-10 on our consolidated financial statements.

There are no other accounting standards that have been issued but not yet adopted that we believe could have a material impact on our consolidated financial statements.

3. COVID-19 PANDEMIC

Since March 2020, the COVID-19 pandemic has led to a significant decrease in consumer demand, a decrease in customer redemptions and elevated refund levels due to changes in consumer behavior and actions taken by governments to control the spread of COVID-19, including quarantines, travel restrictions, as well as business restrictions and shutdowns. The COVID-19 pandemic has had an adverse impact on our financial condition, results of operations and cash flows. Recovery from the COVID-19 pandemic could be volatile and prolonged given the unprecedented and continuously evolving nature of the situation. We continue to monitor the impact of COVID-19 on our business.

We plan to continue to actively manage and optimize our cash balances and liquidity, working capital and operating expenses, although there can be no assurances that we will be able to do so. In 2020, we took several steps to reduce costs, preserve cash in the near-term and improve liquidity, including, but not limited to: reducing our workforce and furloughing staff; continuing to sell Goods on our platform instead of quickly exiting the category; reducing marketing expense by significantly shortening payback thresholds and delaying brand marketing investments; transitioning merchants to redemption payment terms, instead of fixed payment terms; implementing a hiring freeze; eliminating broad-based merit increases for employees; replacing cash compensation with equity compensation in 2020 for all members of our Board of Directors ("the Board"); and amending our Credit Agreement (See Note 10, Financing Arrangements) to, among other things, provide covenant relief through the first quarter of 2021. The future impact of COVID-19 on our business, results of operations, financial condition and liquidity is highly uncertain and will ultimately depend on future developments, including the magnitude and duration of the pandemic and the protective measures associated with reducing its spread.

During the first quarter 2020, we determined the significant deterioration in our financial performance due to the disruption in our operations from COVID-19 and the sustained decrease in our stock price required us to evaluate our long-lived assets and goodwill for impairment, which resulted in impairments of our long-lived assets and goodwill. See Note 6, Property, Equipment and Software, Net, Note 7, Goodwill and Other Intangible Assets, Note 9, Supplemental Consolidated Balance Sheets and Statements of Operations Information and Note 11, Leases, for more information.

In April 2020, the Board approved a multi-phase restructuring plan related to our previously announced strategic shift and as part of the cost cutting measures implemented in response to the impact of COVID-19 on our business. Actions taken under our restructuring plan changed how we used certain long-lived assets and required us to evaluate those long-lived assets for impairment, which resulted in impairments of our long-lived assets. These impairments are included in Restructuring and related charges on the consolidated statement of operations. See Note 16, Restructuring and Related Charges, for more information.

COVID-19 impacted the financial performance of our investees and resulted in an impairment of an Other equity investment and a loss on a fair value option investment that are included in Other income (expense), net on the consolidated statement of operations. See Note 8, Investments, for more information.

4. DISCONTINUED OPERATIONS

In October 2016, we completed a strategic review of our international markets and decided to pursue strategic alternatives for our operations in 12 countries, which were primarily based in Asia and Latin America. The dispositions of our operations in those 12 countries were completed between November 2016 and March 2017. In connection with the dispositions of our operations in Latin America, we recorded indemnification liabilities for certain tax and other matters. See Note 12, Commitments and Contingencies, for additional information about the indemnification liabilities.

For the years ended December 31, 2020 and 2019, we recognized $0.4 million and $2.6 million in income (loss) from discontinued operations, net of tax primarily for a gain related to the expiration of certain contingent liabilities under indemnification agreements. There was no activity related to discontinued operations for the year ended December 31, 2018.

5. BUSINESS COMBINATIONS

On April 30, 2018, we acquired 80% of the outstanding shares of Cloud Savings Company, Ltd. ("Cloud Savings"), a UK-based business that operates online discount code and digital gift card platforms. Concurrent with the acquisition, we entered into an agreement that gave us the right to acquire the remaining outstanding shares of Cloud Savings, and in December 2018 we exercised that right. The primary purpose of this acquisition was to expand digital coupon offerings in our International segment. The aggregate acquisition-date fair value of the consideration transferred for the Cloud Savings acquisition was $74.6 million.

The results of the Cloud Savings acquisition were included in the consolidated financial statements beginning on the acquisition date of April 30, 2018. The revenue and net income of Cloud Savings included in our consolidated statements of operations were $12.9 million and $1.1 million for the period from April 30, 2018 through December 31, 2018. Pro forma results of operations for the Cloud Savings acquisition are not presented because the pro forma effects of that acquisition were not material to our consolidated results of operations.

We did not acquire any other businesses during the years ended December 31, 2020, 2019 and 2018.

(1)As of December 31, 2020, the International reporting unit had a negative carrying value.

Due to the triggering event and subsequent review of goodwill for impairment in the first quarter of 2020, as described in Note 3, COVID-19 Pandemic, we recognized goodwill impairment of $109.5 million within our International segment related to our EMEA operations. In order to evaluate goodwill for impairment in the first quarter 2020, we compared the fair values of our three reporting units (North America, EMEA and Asia Pacific) to their carrying values. In determining fair values for our reporting units, we used the discounted cash flow method and the market multiple valuation approach that use Level 3 inputs. The significant estimates used in the discounted cash flow models are the risk-adjusted discount rates; forecasted revenue, cost of revenue and operating expenses; forecasted capital expenditures and working capital needs; weighted average cost of capital; rates of long-term growth; and income tax rates. These estimates considered the recent deterioration in financial performance of the reporting units as well as the anticipated rate of recovery, and implied risk premiums based on the market prices of our equity and debt as of the assessment date. The significant estimates used in the market multiple valuation approach include identifying business factors such as size, growth, profitability, risk and return on investment and assessing comparable revenue and earnings multiples. We did not recognize any goodwill impairment in our North America or Asia Pacific reporting units.

During the third quarter 2020, we exited our operations in Japan and New Zealand as part of our restructuring plan, which represents the majority of the countries in our Asia Pacific reporting unit. As a result, we combined the remainder of the Asia Pacific reporting unit and the EMEA reporting unit into a single International reporting unit, consistent with how management reviews the operating results of the business. As a result of the change in reporting units, we performed a qualitative assessment of potential goodwill impairment for the new International reporting unit and performed separate qualitative assessments of potential goodwill impairment for our Asia Pacific and EMEA reporting units immediately prior to the change. Based on those assessments, which considered current market conditions and recent business performance, we determined that the likelihood of a goodwill impairment did not reach the more-likely-than-not threshold. Accordingly, we concluded that goodwill relating to those reporting units was not impaired and further quantitative testing was not required to be performed. We did not identify any other triggering events that required us to evaluate goodwill impairment in our North America or International reporting units during the remainder of 2020. Additionally, we concluded that there was no goodwill impairment for either of our reporting units as a result of our annual goodwill impairment analysis. Therefore, we did not recognize additional goodwill impairment for any of our reporting units during the year ended December 31, 2020.

There was no goodwill impairment for the years ended December 31, 2019 and 2018.

Available-for-Sale Securities

The fair value of redeemable preferred shares was $0.0 million as of December 31, 2020 and 2019. We recorded $10.0 million and $5.6 million of impairments of available-for-sale securities for the years ended December 31, 2019 and 2018 due to declines in the financial performance of the investee. Those impairments are classified within Other income (expense), net on the consolidated statements of operations.

In September 2018, we sold an available-for-sale security for total consideration of $8.6 million, which approximated its carrying amount and amortized cost as of the closing date.

Fair Value Option Investments

In connection with the dispositions of controlling stakes in Ticket Monster, an entity based in the Republic of Korea, and Groupon India in prior periods, we obtained minority investments in Monster Holdings LP ("Monster LP") and in Nearbuy Pte Ltd. ("Nearbuy"). We made an irrevocable election to account for both of those investments at fair value with changes in fair value reported in earnings. We elected to apply fair value accounting to those investments because we believe that fair value is the most relevant measurement attribute for those investments, as well as to reduce operational and accounting complexity. Our election to apply fair value accounting to those investments has and may continue to cause fluctuations in our earnings from period to period.

The following table summarizes gains and losses due to changes in fair value of those investments for the years ended December 31, 2020, 2019 and 2018 (in thousands):


	Year Ended December 31,

Monster LP	$	—	$	(69,408)	$	(9,509)
Nearbuy	(1,405)		(3,089)		445
Total	$	(1,405)	$	(72,497)	$	(9,064)

Monster LP

In 2015, we completed the sale of a controlling stake in Ticket Monster to an investor group, whereby we contributed all of the issued and outstanding share capital of Ticket Monster to Monster LP in exchange for Class B units of Monster LP, a newly-formed limited partnership, and $285.0 million in cash consideration. In February 2017, we participated in a recapitalization transaction with Monster LP whereby it exchanged all of its Class B units for 16,609,195 newly issued Class A-1 units. Upon closing of the transaction, we own 57% of the outstanding Class A-1 units, which represents 9% of the total outstanding partnership units.

Following the February 2017 recapitalization transaction, the Class A-1 units are entitled to a $150.0 million liquidation preference, including an $85.0 million liquidation preference attributable to the Class A-1 units held by us, which must be paid prior to any distributions to the holders of the Class A-2, Class B and Class C units. Class A-1 unit holders are also entitled to share in distributions between $950.0 million and $1,494.0 million in accordance with the terms of Monster LP's distribution waterfall and in distributions in excess of $1,494.0 million based on their pro rata ownership of total outstanding partnership units. As a result of the February 2017 recapitalization transaction, we currently hold an investment in the most senior equity units in Monster LP’s capital structure.

GROUPON, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

However, while providing more downside protection, those Class A-1 units provide less opportunity for appreciation than the Class B units previously held by us.

We determined that the fair value of our investment in Monster LP was $0.0 million as of December 31, 2020 and 2019. In 2019 we recognized a $69.4 million loss from changes in the fair value of our investment in Monster LP mainly due to revised cash flow projections provided by Monster LP and an increase in the discount rate applied to those forecasts to 26.0% as of March 31, 2019, as compared with 21.0% as of December 31, 2018. The revisions to the financial projections were made as a result of the deterioration in Ticket Monster's financial condition and continued underperformance compared with prior projections.

Nearbuy

In 2015, Groupon India completed an equity financing transaction with a third-party investor that obtained a majority voting interest in the entity, whereby (a) the investor contributed $17.0 million in cash to Nearbuy, a newly formed Singapore-based entity, in exchange for Series A Preference Shares and (b) we contributed the shares of Groupon India to Nearbuy in exchange for seed preference shares of Nearbuy. In January 2017, Nearbuy issued additional Series A Preference Shares to its controlling investor for total proceeds of $3.0 million. Upon closing of that transaction, the Series A Preference Shares are entitled to a $20.0 million liquidation preference, which must be paid prior to any distributions to other equity holders. In December 2017, Nearbuy sold its subsidiary Nearbuy India Pte Ltd., which represented substantially all of its business operations, to a third-party investor in exchange for a minority investment in the acquirer.

We determined that the fair value of our investment in Nearbuy was $0.0 million as of December 31, 2020 and $1.4 million as of December 31, 2019. During the first quarter 2020, we recognized a $1.4 million loss from changes in the fair value of our investment in Nearbuy due to revised cash flow projections and an increase in the discount rate applied to those forecasts, which increased to 30% as of March 31, 2020, as compared with 20% as of December 31, 2019. The revisions to the financial projections and the increase in the discount rate applied as of March 31, 2020 were due to the deterioration in the financial condition of Nearbuy as a result of COVID-19, which resulted in underperformance as compared with prior projections and an increase to financial projection risk. In 2019, we recognized a $3.1 million loss from changes in the fair value of our investment in Nearbuy due to revised cash flow projections.

Other equity investments represent equity investments without readily determinable fair values. We have elected to record equity investments without readily determinable fair values at cost adjusted for observable price changes and impairments.

In the first quarter 2020, we recorded a $6.7 million impairment to an other equity method investment as a result of revised cash flow projections and a deterioration in financial condition due to COVID-19. This impairment is classified within Other income (expense), net on the consolidated statements of operations. We did not recognize any other impairments to other equity investments during the year ended December 31, 2020.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

In the fourth quarter 2019, we adjusted the carrying value of an other equity investment due to observable price changes in orderly transactions, which resulted in an unrealized gain of $51.4 million. This unrealized gain is classified within Other income (expense), net on the consolidated statements of operations for the year ended December 31, 2019. During the first quarter 2020, we sold 50% of our shares in that investment for total cash consideration of $34.0 million, which approximated the cost adjusted for observable price changes as of December 31, 2019.

For the year ended December 31, 2018, we recorded a $4.6 million impairment of an other equity investment. This impairment is classified within Other income (expense), net on the consolidated statements of operations.

10. FINANCING ARRANGEMENTS

Convertible Senior Notes

On April 4, 2016, we issued $250.0 million in aggregate principal amount of convertible senior notes (the "Notes") in a private placement to A-G Holdings, L.P. ("AGH"). Michael Angelakis, the chairman and chief executive officer of Atairos Group, Inc. ("Atairos"), joined our Board of Directors (the "Board") in connection with the issuance of the Notes. Atairos controls the voting power of AGH. The net proceeds from this offering were $243.2 million after deducting issuance costs. The Notes bear interest at a rate of 3.25% per annum, payable annually in arrears on April 1 of each year, beginning on April 1, 2017. The Notes will mature on April 1, 2022, subject to earlier conversion or redemption.

Each $1,000 of principal amount of the Notes initially is convertible into 9.25926 shares of common stock, which is equivalent to an initial conversion price of $108.00 per share, subject to adjustment upon the occurrence of specified events. Upon conversion, we can elect to settle the conversion value in cash, shares of our common stock, or any combination of cash and shares of our common stock. Holders of the Notes may convert their Notes at their option at any time until the close of business on the scheduled trading day immediately preceding the maturity date. In addition, if specified corporate events occur prior to the maturity date, we may be required to increase the conversion rate for holders who elect to convert based on the effective date of such event and the applicable stock price attributable to the event, as set forth in a table contained in the indenture governing the Notes (the "Indenture"). Based on the closing price of the common stock of $37.99 as of December 31, 2020, the if-converted value of the Notes was less than the principal amount.

With certain exceptions, upon a fundamental change (as defined in the Indenture), the holders of the Notes may require us to repurchase all or a portion of their Notes for cash at a purchase price equal to the principal amount plus accrued and unpaid interest. In addition, we may redeem the Notes, at our option, at a purchase price equal to the principal amount plus accrued and unpaid interest on or after April 1, 2020, if the closing sale price of the common stock exceeds 150% of the then-current conversion price for 20 or more trading days in the 30 consecutive trading-day period preceding the exercise of this redemption right.

The Notes are senior unsecured obligations that rank equal in right of payment to all senior unsecured indebtedness and rank senior in right of payment to any indebtedness that is contractually subordinated to the Notes.

The Indenture includes customary events of default. If an event of default, as defined in the Indenture, occurs and is continuing, the principal amount of the Notes and any accrued and unpaid interest may be declared

GROUPON, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

immediately due and payable. In the case of bankruptcy or insolvency, the principal amount of the Notes and any accrued and unpaid interest would automatically become immediately due and payable.

We have separated the Notes into their liability and equity components in the accompanying consolidated balance sheets. The carrying amount of the liability component was calculated by measuring the fair value of a similar liability that does not have an associated conversion feature. The carrying amount of the equity component, representing the conversion option, was determined by deducting the fair value of the liability component from the principal amount of the Notes. The difference between the principal amount of the Notes and the liability component (the "debt discount") is amortized to interest expense at an effective interest rate of 9.75% over the term of the Notes. The equity component of the Notes is included in additional paid-in capital in the consolidated balance sheets and is not remeasured as long as it continues to meet the conditions for equity classification.

We incurred transaction costs of approximately $6.8 million related to the issuance of the Notes. Those transaction costs were allocated to the liability and equity components in the same manner as the allocation of the proceeds from the Notes. Transaction costs attributable to the liability component of $4.8 million were recorded as a debt discount in the consolidated balance sheet and are being amortized to interest expense over the term of the Notes. Transaction costs attributable to the equity component of $2.0 million were recorded in stockholders' equity as a reduction of the equity component.

The carrying amount of the Notes consisted of the following as of December 31, 2020 and 2019 (in thousands):


	December 31,
	2020		2019
Liability component:
Principal amount	$	250,000	$	250,000
Less: debt discount	(20,510)		(35,131)
Net carrying amount of liability component	$	229,490	$	214,869

Net carrying amount of equity component	$	67,014	$	67,014

The estimated fair value of the Notes as of December 31, 2020 and 2019 was $263.3 million and $262.7 million, and was determined using a lattice model. We classified the fair value of the Notes as a Level 3 measurement due to the lack of observable market data over fair value inputs such as our stock price volatility over the term of the Notes and our cost of debt.

As of December 31, 2020, the remaining term of the Notes is approximately 1 years and 3 months. During the years ended December 31, 2020, 2019 and 2018, we recognized interest costs on the Notes as follows (in thousands):


	Year Ended December 31,
	2020		2019		2018
Contractual interest (3.25% of the principal amount per annum)	$	8,128	$	8,128	$	8,128
Amortization of debt discount	14,621		13,200		11,916
Total	$	22,749	$	21,328	$	20,044

Note Hedges and Warrants

In May 2016, we purchased convertible note hedges with respect to our common stock for a cost of $59.1 million from certain bank counterparties. The convertible note hedges provide us with the right to purchase up to 2.3 million shares of our common stock at an initial strike price of $108.00 per share, which corresponds to the initial conversion price of the Notes, and are exercisable upon conversion of the Notes. The convertible note hedges are intended to reduce the potential economic dilution upon conversion of the Notes. The convertible note hedges are separate transactions and are not part of the terms of the Notes. Holders of the Notes do not have any rights with respect to the convertible note hedges.

GROUPON, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

In May 2016, we also sold warrants for total cash proceeds of $35.5 million to certain bank counterparties. The warrants provide the counterparties with the right to purchase up to 2.3 million shares of our common stock at a strike price of $170.00 per share. The warrants expire on various dates between July 1, 2022 and August 26, 2022 and are exercisable on their expiration dates. The warrants are separate transactions and are not part of the terms of the Notes or convertible note hedges. Holders of the Notes and convertible note hedges do not have any rights with respect to the warrants.

The amounts paid and received for the convertible note hedges and warrants were recorded in additional paid-in capital in the consolidated balance sheets as of December 31, 2020 and 2019. The convertible note hedges and warrants are not remeasured as long as they continue to meet the conditions for equity classification. The amounts paid for the convertible note hedges are tax deductible over the term of the Notes, while the proceeds received from the warrants are not taxable.

Under the if-converted method, the shares of common stock underlying the conversion option in the Notes are included in the diluted earnings per share denominator and the interest expense on the Notes, net of tax, is added to the numerator. However, upon conversion, there will be no economic dilution from the Notes, as exercise of the convertible note hedges eliminates any dilution from the Notes that would have otherwise occurred when the price of our common stock exceeds the conversion price. Taken together, the purchase of the convertible note hedges and sale of warrants are intended to offset any actual dilution from the conversion of the Notes and to effectively increase the overall conversion price from $108.00 to $170.00 per share.

Revolving Credit Agreement

In May 2019, we entered into a second amended and restated senior secured revolving credit agreement which provided for aggregate principal borrowings of up to $400.0 million (prior to the Amendment described below) and matures in May 2024.

In July 2020, we entered into an amendment to the revolving credit agreement (the "Amendment" and the revolving credit agreement as amended, the "Amended Credit Agreement") in order to provide us with operational flexibility and covenant relief through the end of the first quarter of 2021 (the "Suspension Period") in light of the ongoing impacts of COVID-19 on our business. In addition to the covenant relief described below, the Amendment permanently reduces borrowing capacity under our senior secured revolving credit facility from $400.0 million to $225.0 million.

We deferred debt issuance costs of $3.2 million as a result of entering into the Amended Credit Agreement. Deferred debt issuance costs are included within Other non-current assets on the consolidated balance sheet as of December 31, 2020 and are amortized to interest expense over the term of the respective agreement.

Pursuant to the Amendment, during the Suspension Period, the Company will be exempt from certain covenant restrictions, namely the requirements to maintain a maximum funded indebtedness to EBITDA ratio, a maximum senior secured indebtedness to EBITDA ratio, a minimum fixed charge coverage ratio, unrestricted cash of not less than $250.0 million and a minimum liquidity balance (including any undrawn amounts under the credit facility) of at least 70% of our accrued merchant and supplier payables balance (collectively, the "Existing Financial Covenants"). Additionally, the Amendment provides that, during the Suspension Period, we will be required to maintain specified minimum quarterly EBITDA levels and to maintain a monthly minimum liquidity balance (including any undrawn amounts under the credit facility) of at least 100% of our accrued merchant and supplier payables balance for such month plus $50.0 million. Following the Suspension Period, we will be subject to the Existing Financial Covenants.

In addition, under the Amended Credit Agreement, we are subject to various covenants, including customary restrictive covenants that limit our ability to, among other things: incur additional indebtedness; make dividend and other restricted payments, including limiting the amount of our share repurchases; enter into sale and leaseback transactions; make investments, loans or advances; grant or incur liens on assets; sell assets; engage in mergers, consolidations, liquidations or dissolutions; and engage in transactions with related parties and other affiliates. The Amendment further restricts certain of these negative covenants during the Suspension Period, including our ability to make share repurchases, acquisitions, investments and to incur additional indebtedness and liens.

GROUPON, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Non-compliance with the covenants under the Amended Credit Agreement may result in termination of the commitments thereunder and any then outstanding borrowings may be declared due and payable immediately. We have the right to terminate the Amended Credit Agreement or reduce the available commitments at any time.

The Amendment also increases interest rates through the end of the first quarter of 2021, raising the alternative base rate and Canadian prime spreads to 1.50%, the fixed rate spreads to 2.50% and the commitment fee to 0.4% on the daily amount of the unused commitments under the Amended Credit Agreement. Following the Suspension Period, the applicable spread and commitment fee will revert to pre-Amendment levels, which provides for (a) interest at a rate per annum equal to (i) an adjusted LIBO rate or (ii) a customary base rate (with loans denominated in certain currencies bearing interest at rates specific to such currencies) plus an additional margin ranging between 0.50% and 2.00% and (b) commitment fees ranging from 0.25% to 0.35% on the daily amount of unused commitments. The Amended Credit Agreement also provides for the issuance of up to $75.0 million in letters of credit, provided that the sum of outstanding borrowings and letters of credit do not exceed the maximum funding commitment of $225.0 million.

The Amended Credit Agreement is secured by substantially all of our tangible and intangible assets, including a pledge of 100% of the outstanding capital stock of substantially all of our direct and indirect domestic subsidiaries and 65% of the shares or equity interests of first-tier foreign subsidiaries and each U.S. entity whose assets substantially consist of capital stock and/or intercompany debt of one or more foreign subsidiaries, subject to certain exceptions. Certain of our domestic and foreign subsidiaries are guarantors under the Amended Credit Agreement.

We had $200.0 million of borrowings and $20.6 million of outstanding letters of credit under the Amended Credit Agreement as of December 31, 2020. We had no borrowings and $18.1 million of outstanding letters of credit under the credit agreement as of December 31, 2019.

11. LEASES

Adoption of ASC Topic 842, Leases

On January 1, 2019, we adopted ASC Topic 842 using the modified retrospective transition method. Beginning on January 1, 2019, our consolidated financial statements are presented in accordance with the revised policies, while prior period amounts are not adjusted and continue to be reported in accordance with our historical policies. Aside from the impact to our consolidated balance sheet discussed in Note 2, Summary of Significant Accounting Policies, lease presentation within the consolidated statements of operations and consolidated statements of cash flows are substantially consistent with historical treatment.

General Description of Leases

Our operating leases primarily consist of leases for real estate throughout the world with lease expirations between 2021 and 2027. These arrangements typically do not transfer ownership of the underlying asset as we do not assume, nor do we intend to assume, the risks and rewards of ownership. Our finance leases are related to purchases of property and equipment, primarily computer hardware, with expirations between 2021 and 2023. We have also subleased certain office facilities under operating lease agreements, with expirations between 2023 and 2026.

We lease our headquarters located in Chicago, Illinois ("600 West Chicago"). Our lease agreement for 600 West Chicago extends through January 31, 2026 and includes rent escalations that range from one to two percent per year, as well as expansion options and a five-year renewal option. The 600 West Chicago lease represents $66.8 million of the estimated future payments under operating leases shown in the table below. We account for the 600 West Chicago lease as an operating lease and recognize rent expense on a straight-line basis, taking into account rent escalations and lease incentives. We sublease a portion of our office space at 600 West Chicago to Uptake, Inc., a Lightbank LLC portfolio company as a related party transaction. The sublease was a market rate transaction on terms that we believe are no less favorable than would have been reached with an unrelated party. The sublease extends through January 31, 2026 and sublease rentals over the entire term total $18.2 million.

For more information about our lease accounting policies, including lease recognition policy and significant assumptions and judgments used, see Note 2, Summary of Significant Accounting Policies.

Legal Matters and Other Contingencies

From time to time, we are party to various legal proceedings incident to the operation of our business. For example, we currently are involved in proceedings brought by merchants, employment and related matters, intellectual property infringement suits, customer lawsuits, stockholder claims relating to U.S. securities law, consumer class actions and suits alleging, among other things, violations of state consumer protection or privacy laws.

On April 28, 2020, an individual plaintiff filed a securities fraud class action complaint in the United States District Court for the Northern District of Illinois, and in July 2020, another individual was appointed as lead plaintiff. The lawsuit covers the time period from July 30, 2019 through February 18, 2020. The lead plaintiff alleges that Groupon and certain of its officers made materially false and/or misleading statements or omissions regarding its business, operations and prospects, specifically as it relates to reiterating its full year guidance on November 4, 2019 and the Groupon Select program. Groupon filed a motion to dismiss the complaint in this matter and is awaiting a ruling by the court. We intend to vigorously defend against these allegations, which we believe to be without merit.

In addition, third parties have from time to time claimed, and others may claim in the future, that we have infringed their intellectual property rights. We are subject to intellectual property disputes, including patent infringement claims, and expect that we will continue to be subject to intellectual property infringement claims as our services expand in scope and complexity. In the past, we have litigated such claims, and we are presently involved in several patent infringement and other intellectual property-related claims, including pending litigation or trademark disputes relating to, for example, our Goods category, some of which could involve potentially substantial claims for damages or injunctive relief. We may also become more vulnerable to third-party claims as laws such as the Digital Millennium Copyright Act are interpreted by the courts, and we become subject to laws in jurisdictions where the underlying laws with respect to the potential liability of online intermediaries are either unclear or less favorable. We believe that additional lawsuits alleging that we have violated patent, copyright or trademark laws may be filed against us. Intellectual property claims, whether meritorious or not, are time consuming and often costly to resolve, could require expensive changes in our methods of doing business or the goods we sell, or could require us to enter into costly royalty or licensing agreements.

We also are subject to consumer claims or lawsuits relating to alleged violations of consumer protection or privacy rights and statutes, some of which could involve potentially substantial claims for damages, including statutory or punitive damages. Consumer and privacy related claims or lawsuits, whether meritorious or not, could be time consuming, result in costly litigation, damage awards, fines and penalties, injunctive relief or increased costs of doing business through adverse judgment or settlement, or require us to change our business practices, sometimes in expensive ways.

We are also subject to, or in the future may become subject to, a variety of regulatory inquiries, audits, and investigations across the jurisdictions where we conduct our business, including, for example, inquiries related to consumer protection, employment matters and/or hiring practices, marketing practices, tax, unclaimed property and privacy rules and regulations. Any regulatory actions against us, whether meritorious or not, could be time consuming, result in costly litigation, damage awards, fines and penalties, injunctive relief or increased costs of doing business through adverse judgment or settlement, require us to change our business practices in expensive ways, require significant amounts of management time, result in the diversion of significant operational resources, materially damage our brand or reputation, or otherwise harm our business.

We establish an accrued liability for loss contingencies related to legal and regulatory matters when the loss is both probable and reasonably estimable. Those accruals represent management's best estimate of probable losses and, in such cases, there may be an exposure to loss in excess of the amounts accrued. For certain of the matters described above, there are inherent and significant uncertainties based on, among other factors, the stage of the proceedings, developments in the applicable facts of law, or the lack of a specific damage claim. However, we believe that the amount of reasonably possible losses in excess of the amounts accrued for those matters would not have a material adverse effect on our business, consolidated financial position, results of operations or cash flows. Our accrued liabilities for loss contingencies related to legal and regulatory matters may change in the future as a result of new developments, including, but not limited to, the occurrence of new legal matters, changes in the law or regulatory environment, adverse or favorable rulings, newly discovered facts relevant to the matter, or changes in the strategy for the matter. Regardless of the outcome, litigation and other regulatory matters can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.

Indemnifications

In connection with the disposition of our operations in Latin America in 2017, we recorded $5.4 million in indemnification liabilities for certain tax and other matters upon the closing of the transactions as an adjustment to the net loss on the dispositions within discontinued operations at their fair value. We estimated the indemnification liabilities using a probability-weighted expected cash flow approach. In 2020 and 2019, we decreased our indemnification liabilities due to the expiration of certain indemnification obligations. The resulting benefit of $0.4 million and $2.2 million is recorded within Income (loss) from discontinued operations on the consolidated statements of operations for the years ended December 31, 2020 and 2019. Our remaining indemnification liabilities were $2.8 million as of December 31, 2020. We estimate that the total amount of obligations that are reasonably possible to arise under the indemnifications in excess of amounts accrued as of December 31, 2020 is approximately $11.7 million.

In the normal course of business to facilitate transactions related to our operations, we indemnify certain parties, including employees, lessors, service providers, merchants, and counterparties to investment agreements and asset and stock purchase agreements with respect to various matters. We have agreed to hold certain parties harmless against losses arising from a breach of representations or covenants, or other claims made against those parties. These agreements may limit the time within which an indemnification claim can be made and the amount of the claim. We are also subject to increased exposure to various claims as a result of our divestitures and acquisitions, particularly in cases where we are entering into new businesses in connection with such acquisitions. We may also become more vulnerable to claims as we expand the range and scope of our services and are subject to laws in jurisdictions where the underlying laws with respect to potential liability are either unclear or less favorable. In addition, we have entered into indemnification agreements with our officers, directors and underwriters, and our bylaws contain similar indemnification obligations that cover officers, directors, employees and other agents.

Except as noted above, it is not possible to determine the maximum potential amount under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. Historically, any payments that we have made under these agreements have not had a material impact on our operating results, financial position or cash flows.

13. STOCKHOLDERS' EQUITY

Reverse Stock Split

On June 9, 2020, our stockholders approved amendments to our Restated Certificate of Incorporation to effect a reverse stock split of our shares of common stock, and our Board approved a final reverse stock split ratio of 1-for-20 and a corresponding reduction in the number of authorized shares of our common stock. The reverse stock split became effective on June 10, 2020. On the effective date, every 20 shares of issued and outstanding common stock were combined and converted into one issued and outstanding share of common stock. The number of authorized shares of Common Stock was reduced proportionately. Fractional shares were cancelled and stockholders received cash in lieu thereof and the par value per share of common stock remains unchanged. A proportionate adjustment was also made to the maximum number of shares of common stock issuable under the Groupon, Inc. Stock Plans (the "Plans"), and the Groupon, Inc. 2012 Employee Stock Purchase Plan, as amended ("ESPP").

As a result, the number of shares and income (loss) per share disclosed throughout this Annual Report on Form 10-K have been retrospectively adjusted to reflect the reverse stock split.

Preferred Stock

Our Board of Directors has the authority, without approval by the stockholders, to issue up to a total of 50,000,000 shares of preferred stock in one or more series. The Board may establish the number of shares to be included in each such series and may fix the designations, preferences, powers and other rights of the shares of a series of preferred stock. The Board could authorize the issuance of preferred stock with voting or conversion rights that could dilute the voting power or rights of the holders of our common stock. As of December 31, 2020 and 2019, there were no shares of preferred stock outstanding.

GROUPON, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Common Stock

Pursuant to our restated certificate of incorporation, the Board has the authority to issue up to a total of 100,500,000 shares of common stock. Each holder of common stock is entitled to one vote per share on any matter that is submitted to a vote of stockholders. In addition, holders of our common stock will vote as a single class of stock on any matter that is submitted to a vote of stockholders.

Share Repurchase Program

In May 2018, the Board authorized us to repurchase up to $300.0 million of our common stock under our share repurchase program. During the year ended December 31, 2020, we did not repurchase any shares under the program. As of December 31, 2020, up to $245.0 million of common stock remained available for purchase under our program. The timing and amount of share repurchases, if any, will be determined based on market conditions, limitations under the Amended Credit Agreement, share price, available cash and other factors, and the share repurchase program may be terminated at any time.

14. COMPENSATION ARRANGEMENTS

Groupon, Inc. Stock Plans

In January 2008, we adopted the 2008 Stock Option Plan, as amended (the "2008 Plan"), under which options for up to 3,230,925 shares of common stock were authorized to be issued to employees, consultants and directors. The 2008 Plan was frozen in December 2010. In April 2010, we established the Groupon, Inc. 2010 Stock Plan, as amended in April 2011 (the "2010 Plan"), under which options and restricted stock units ("RSUs") for up to 1,000,000 shares of common stock were authorized for future issuance to employees, consultants and directors. No new awards may be granted under the 2010 Plan following our initial public offering in November 2011. In August 2011, we established the Groupon, Inc. 2011 Stock Plan (the "2011 Plan"), as amended in November 2013, May 2014, June 2016 and April 2019, under which options, RSUs and performance stock units for up to 9,375,000 shares of common stock were authorized for future issuance to employees, consultants and directors.

The Groupon, Inc. Stock Plans described above (the "Plans") are administered by the Compensation Committee of the Board (the "Compensation Committee"). As of December 31, 2020, 3,135,422 shares of common stock were available for future issuance under the Plans.

Restricted Stock Units

The restricted stock units granted under the Plans generally have vesting periods between one and four years and are amortized on a straight-line basis over their requisite service period.

The table below summarizes restricted stock unit activity under the Plans for the year ended December 31, 2020:


	Restricted Stock Units		Weighted- Average Grant Date Fair Value (per share)
Unvested at December 31, 2019	$	1,527,014	$	74.80
Granted	1,836,665		24.92
Vested	(679,944)		72.25
Forfeited	(830,728)		62.48
Unvested at December 31, 2020	$	1,853,007	$	31.91

The weighted-average grant date fair value of restricted stock units granted in 2019 and 2018 was $68.80 and $91.80. The fair value of restricted stock units that vested during each of the three years ended December 31, 2020, 2019 and 2018 was $19.2 million, $43.8 million and $64.1 million. As of December 31, 2020, $38.8 million of unrecognized compensation costs related to unvested employee restricted stock units are expected to be recognized over a remaining weighted-average period of 0.92 years.

Performance Share Units

We grant performance share units under the Plans that vest in shares of our common stock upon the achievement of financial and operational targets specified in the respective award agreement ("Performance Share Units"). During the year ended December 31, 2019, we also granted performance share units subject to a market condition ("Market-based Performance Share Units").

The Market-based Performance Share Units will vest if our average daily closing stock price is equal to or greater than $120.00 per share over a period of 30 consecutive trading days prior to December 31, 2022 or if a change in control occurs during the performance period at the specified stock price (and on a proportional basis for a change in control price between the grant date price and the specified stock price). We used a Monte Carlo simulation to calculate the grant date fair value of the awards and the related derived service period over which we recognized the expense. The key inputs used in the Monte Carlo simulation were the risk-free rate, our volatility of 49.8% and our cost of equity of 12.8%.

Our Performance Share Units and Market-based Performance Share Units are subject to continued employment through the performance period dictated by the award and certification by the Compensation Committee that the specified performance conditions have been achieved.

The table below summarizes Performance Share Unit activity under the Plans for the year ended December 31, 2020:


	Performance Share Units	Weighted-Average Grant Date Fair Value (per unit)		Market-based Performance Share Units	Weighted-Average Grant Date Fair Value (per unit)

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

As of December 31, 2020, $1.3 million of unrecognized compensation costs related to unvested Performance Share Units are expected to be recognized over a remaining weighted-average period of 1.54 years. We have recognized all compensation costs related to our unvested Market-Based Performance Share Units.

15. REVENUE RECOGNITION

In connection with most of our product and service revenue transactions, we collect cash from credit card payment processors shortly after a sale occurs. For transactions in which we earn commissions when customers make purchases with retailers using digital coupons accessed through our websites and mobile applications, we generally collect payment from affiliate networks on terms ranging from 30 to 150 days.

Contract Balances

A substantial majority of our deferred revenue relates to product sales for which revenue will be recognized as the products are delivered to customers, generally within one week following the balance sheet date. Our deferred revenue was $11.2 million as of December 31, 2020. As of December 31, 2019 and 2018, our deferred revenue was $18.0 million and $25.5 million, all of which was recognized during the years ended December 31, 2020 and 2019, respectively.

Customer Credits

We issue credits to customers that can be applied to future purchases through our online marketplaces. Credits are primarily issued as consideration for refunds. To a lesser extent, credits are issued for customer relationship purposes. The following table summarizes the activity in the liability for customer credits for the years ended December 31, 2020 and 2019 (in thousands):

16. RESTRUCTURING AND RELATED CHARGES

In April 2020, the Board approved a multi-phase restructuring plan of up to $105.0 million of total pretax charges related to our previously announced strategic shift and as part of the cost cutting measures implemented in response to the impact of COVID-19 on our business. We expect to incur total pretax charges of $75.0 million to $105.0 million in connection with the multi-phase restructuring actions through the end of 2021. The first phase of the restructuring actions included an overall reduction of approximately 1,200 positions globally and the exit or discontinuation of the use of certain leases and other assets. The majority of the first phase of workforce reductions and impairments of our right-of-use and other long-lived assets occurred during the second quarter 2020. In the third quarter 2020, we initiated the second phase of our restructuring plan, which included additional workforce reductions and the exit of our operations in New Zealand and Japan. The majority of our restructuring charges are expected to be paid in cash and primarily relate to employee severance and benefits expenses, facilities-related costs and professional advisory fees. We will continue to evaluate our cost structure, including additional workforce reductions, as part of our restructuring plan. Costs incurred related to the restructuring plan are classified as Restructuring and related charges on the consolidated statements of operations.

The following table summarizes costs incurred by segment related to the restructuring plan for the year ended December 31, 2020 (in thousands):


	Year Ended December 31, 2020

As a part of our restructuring plan, we vacated several of our leased facilities, and many of those facilities are being actively marketed for sublease or we are in negotiations with the landlord to potentially terminate or modify those leases. Rent expense, including amortization of the right-of-use asset and accretion of the operating lease liability, sublease income and other variable lease costs related to the leased facilities vacated as part of our restructuring plan are presented within Restructuring and related charges in the consolidated statements of operations. The current and non-current liabilities associated with these leases continue to be presented within Other current liabilities and Operating lease obligations in the consolidated balance sheets.

Due to actions taken under our restructuring plan, we recognized $18.1 million and $3.5 million of long-lived asset impairment in our North America and International segments during the year ended December 31, 2020.

(1)Tax rates in foreign jurisdictions were generally lower than the U.S. federal statutory rate through December 31, 2020. This results in an adverse impact to the provision (benefit) for income taxes in this rate reconciliation for the years ended December 31, 2020, 2019 and 2018 prior to the impact of valuation allowances, due to the net pretax losses from continuing operations in certain foreign jurisdictions with lower tax rates.

(2)During the year ended December 31, 2019, we updated our net operating losses to remove deferred tax assets that could never be utilized due to IRC Section 382 limitations. The amount of State income taxes, net of federal benefits, and state tax credits, Change in valuation allowances and Non-deductible or non-taxable items for the year ended December 31, 2018 have been updated from $2.0 million, $3.8 million and $7.3 million previously reported to reflect that change.

We have incurred significant losses in recent periods and had an accumulated deficit of $1,320.9 million as of December 31, 2020. As a result, we maintained valuation allowances against our domestic deferred tax assets and substantially all of our foreign deferred tax assets as of December 31, 2020 and 2019 to reduce their carrying values to amounts that are realizable either through future reversals of existing taxable temporary differences or through taxable income in carryback years for the applicable jurisdictions.

We had $77.5 million of state net operating loss carryforwards as of December 31, 2020, which began expiring in the current period. As of December 31, 2020, we had $465.2 million of foreign net operating loss carryforwards, a significant portion of which carry forward for an indefinite period.

We are subject to taxation in the United States, state jurisdictions and foreign jurisdictions. Significant judgment is required in determining the worldwide provision for income taxes and recording the related income tax assets and liabilities. We recognize the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more-likely-than-not criterion, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority.

The following table summarizes activity related to our gross unrecognized tax benefits, excluding interest and penalties, for the years ended December 31, 2020, 2019 and 2018 (in thousands):


	Year Ended December 31,
	2020		2019		2018
Beginning Balance	$	64,361	$	87,637	$	87,359
Increases related to prior year tax positions	8,389		3,754		1,500

Foreign currency translation	2,397		(474)		713
Ending Balance	$	48,960	$	64,361	$	87,637

The total amount of unrecognized tax benefits as of December 31, 2020, 2019 and 2018 that, if recognized, would affect the effective tax rate are $19.9 million, $25.1 million and $33.3 million.

We recognized $1.0 million, $1.4 million and $1.6 million of interest and penalties within Provision (benefit) for income taxes on our consolidated statements of operations for the years ended December 31, 2020, 2019 and 2018. Total accrued interest and penalties as of December 31, 2020 and 2019 were $4.9 million and $4.9 million, and are included within Other non-current liabilities in our consolidated balance sheets.

We are currently under audit by several foreign jurisdictions. It is likely that the examination phase of some of those audits will conclude in the next 12 months. There are many factors, including factors outside of our control, which influence the progress and completion of those audits. We recognized income tax benefits of $8.9 million, $12.3 million and $7.9 million for the years ended December 31, 2020, 2019 and 2018, as a result of new information that impacted our estimates of the amounts that are more-likely-than not of being realized upon settlement of the related tax positions and due to expirations of the applicable statutes of limitations. We are subject to claims for tax assessments by foreign jurisdictions, including a proposed assessment for $126.4 million, inclusive of estimated incremental interest from the original assessment. We believe that the assessment, which primarily relates to transfer pricing on transactions occurring in 2011, is without merit and we intend to vigorously defend ourselves in that matter. In addition to any potential increases in our liabilities for uncertain tax positions from the ultimate resolution of that assessment, we believe that it is reasonably possible that reductions of up to $3.4 million in unrecognized tax benefits may occur within the 12 months following December 31, 2020 upon closing of income tax audits or the expiration of applicable statutes of limitations.

In general, it is our practice and intention to reinvest the earnings of our non-U.S. subsidiaries in those operations. Additionally, while we did not incur the deemed repatriation tax, an actual repatriation from our non-U.S. subsidiaries could be subject to foreign and U.S. state income taxes. Aside from limited exceptions for which the related deferred tax liabilities recognized as of December 31, 2020 and 2019 are immaterial, we do not intend to distribute earnings of foreign subsidiaries for which we have an excess of the financial reporting basis over the tax basis of our investments and therefore have not recorded any deferred taxes related to such amounts. The actual tax cost resulting from a distribution would depend on income tax laws and circumstances at the time of distribution. Determination of the amount of unrecognized deferred tax liability related to the excess of the financial reporting basis over the tax basis of our foreign subsidiaries is not practical due to the complexities associated with the calculation.

Groupon uses a cost-sharing arrangement under which controlled members agree to share the costs and risks of developing intangible properties in accordance with their reasonably anticipated share of benefits from the intangibles. In 2019, the Ninth Circuit Court of Appeals entered a decision in Altera Corp. v. Commissioner requiring related parties in an intercompany cost-sharing arrangement to share expenses related to stock-based compensation. Altera then petitioned the United States Supreme Court to review the Ninth Circuit's decision. In June 2020, the Supreme Court denied this petition, and accordingly, the Ninth Circuit's Altera decision stands. The Altera decision did not have a material impact on our provision for income taxes for the years ended December 31, 2020 and 2019.

18. VARIABLE INTEREST ENTITY

We have an arrangement with a strategic partner to offer deals related to live events, and a limited liability company ("LLC") has been established to administer that arrangement. Groupon and the strategic partner each own 50% of the outstanding LLC interests, and income and cash flows of the LLC are allocated based on agreed upon percentages specified in the related LLC agreement.

Our obligations associated with our interests in the LLC are primarily administering transactions, contributing intellectual property, identifying deals and promoting the sale of deal offerings, coordinating the distribution of deal offerings and providing the record keeping.

Under the LLC agreement, as amended, the LLC shall be dissolved upon the occurrence of any of the following events: (1) either party becoming a majority owner; (2) July 2022; (3) certain elections of Groupon or the strategic partner based on the operational performance of the LLC or other changes to certain terms in the agreement; (4) election of either Groupon or the strategic partner in the event of bankruptcy by the other party; (5) sale of the LLC; or (6) a court's dissolution of the LLC.

We have determined that the LLC is a VIE and that we are its primary beneficiary. We consolidate the LLC because we have the power to direct the activities of the LLC that most significantly impact the LLC's economic performance. In particular, we identify and promote the deal offerings, provide all of the operational and back office support, present the LLC's deal offerings via our websites and mobile applications and provide the editorial resources that create the verbiage for the related deal offers.

19. FAIR VALUE MEASUREMENTS

Fair value is defined under U.S. GAAP as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or a liability.

To increase the comparability of fair value measures, the following hierarchy prioritizes the inputs in valuation methodologies used to measure fair value:

Level 1 - Measurements that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2 - Measurements that include other inputs that are directly or indirectly observable in the marketplace.

Level 3 - Measurements derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. These fair value measurements require significant judgment.

In determining fair value, we use various valuation approaches within the fair value measurement framework. The valuation methodologies used for our assets and liabilities measured at fair value and their classification in the valuation hierarchy are summarized below:

Fair value option investments and available-for-sale securities. We use the discounted cash flow method, which is an income approach, to estimate the fair value of the investees. The key inputs to determining fair values under that approach are cash flow forecasts and discount rates. We also use a market approach valuation technique, which is based on market multiples of guideline companies, to determine the fair value of each entity.

We also have investments in redeemable preferred shares. We measure the fair value of those available-for-sale securities using the discounted cash flow method.

We have classified our fair value option investments and our investments in available-for-sale securities as Level 3 due to the lack of observable market data over fair value inputs such as cash flow projections and discount rates. Increases in projected cash flows and decreases in discount rates contribute to increases in the estimated fair values of the fair value option investments and available-for-sale securities, whereas

106

GROUPON, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

decreases in projected cash flows and increases in discount rates contribute to decreases in their fair values. Our fair value option investments were $0.0 million and $1.4 million as of December 31, 2020 and 2019.

Contingent consideration. We are subject to a contingent consideration arrangement to transfer a maximum payout in cash of $2.5 million to the former owners of a business acquired on April 30, 2018. See Note 5, Business Combinations, for further discussion of that acquisition.

The following table provides a roll-forward of the fair value of recurring Level 3 fair value measurements for the years ended December 31, 2020, 2019 and 2018 (in thousands):

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

Certain assets and liabilities are measured at fair value on a nonrecurring basis, including assets that are written down to fair value as a result of an impairment or increased due to an observable price change in an orderly transaction.

We recognized $109.5 million in non-cash impairment charges related to goodwill and $44.0 million in non-

107

GROUPON, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

cash impairment charges related to long-lived assets during the year ended December 31, 2020, of which $21.6 million is included in Restructuring and related charges on our consolidated statements of operations. See Note 6, Property, Equipment and Software, Net, Note 7, Goodwill and Other Intangible Assets, Note 11, Leases and Note 16, Restructuring and Related Charges, for additional information.

We recognized a $6.7 million impairment related to an other equity method investment during the year ended December 31, 2020. See Note 8, Investments, for additional information.

For the year ended December 31, 2019, we adjusted the carrying value of an other equity investment for observable price changes in an orderly transaction, which resulted in an unrealized gain of $51.4 million. See Note 8, Investments, for additional information.

For the year ended December 31, 2018, we recorded a $4.6 million impairment of an other equity investment. To determine the fair value of the investment, we considered the financial condition of the investee and applied a market approach. We have classified the fair value measurement of that other equity investment as Level 3 because it involves significant unobservable inputs. See Note 8, Investments, for additional information.

Estimated Fair Value of Financial Assets and Liabilities Not Measured at Fair Value

Our financial instruments not carried at fair value consist primarily of accounts receivable, restricted cash, accounts payable, accrued merchant and supplier payables and accrued expenses. The carrying values of those assets and liabilities approximate their respective fair values as of December 31, 2020 and 2019 due to their short-term nature.

20. INCOME (LOSS) PER SHARE

Basic net income (loss) per share is computed using the weighted-average number of common shares outstanding during the period. Diluted net income (loss) per share is computed using the weighted-average number of common shares and the effect of potentially dilutive securities outstanding during the period. Potentially dilutive securities include stock options, restricted stock units, performance share units, performance bonus awards, ESPP shares, warrants and convertible senior notes. If dilutive, those potentially dilutive securities are reflected in diluted net income (loss) per share using the treasury stock method, except for the convertible senior notes, which are subject to the if-converted method.

The following table sets forth the computation of basic and diluted net income (loss) per share of common stock for the years ended December 31, 2020, 2019 and 2018 (in thousands, except share amounts and per share amounts):

Total	6,716,581	6,407,194	6,259,285

We had outstanding Market-based Performance Share Units as of December 31, 2020 that were eligible to vest into shares of common stock subject to the achievement of specified performance or market conditions. Contingently issuable shares are excluded from the computation of diluted earnings per share if, based on current period results, the shares would not be issuable if the end of the reporting period were the end of the contingency period. As of December 31, 2020, there were up to 57,668 shares of common stock issuable upon vesting of outstanding Market-based Performance Share Units that were excluded from the table above as the performance or market conditions were not satisfied as of the end of the period.

21. SEGMENT INFORMATION

The segment information reported in the tables below reflects the operating results that are regularly reviewed by our chief operating decision maker to assess performance and make resource allocation decisions. During the third quarter 2020, we changed our measure of segment profitability from operating income (loss) to contribution profit, defined as gross profit less marketing expense, which is consistent with how management reviews the operating results of the segments. Contribution profit measures the amount of marketing investment needed to generate gross profit. Other operating expenses are excluded from contribution profit as management does not review those expenses by segment. Our operations are organized into two segments: North America and International.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, has evaluated the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the Exchange Act), as of the end of the period covered by this Annual Report on Form 10-K.

Based on this evaluation, our management concluded that, as of December 31, 2020, our disclosure controls and procedures are effective to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rule 13a-15(f) of the Exchange Act. Our management conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Our internal control over financial reporting includes policies and procedures that provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes in accordance with U.S. generally accepted accounting principles. Based on this evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2020. Management reviewed the results of its assessment with our Audit Committee. The effectiveness of our internal control over financial reporting as of December 31, 2020 has been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in its report which is included below.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the quarter ended December 31, 2020 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. As a result of the COVID-19 pandemic, our employees have been working remotely. We have not identified any material changes to our internal controls over financial reporting as a result of COVID-19 or related changes to our working environment. We are continually monitoring and assessing the impact the COVID-19 pandemic and related restrictions have on our own internal controls to minimize the effect on their design and operating effectiveness.

Limitations on Effectiveness of Controls and Procedures

In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs.

We have audited the internal control over financial reporting of Groupon, Inc. and subsidiaries (the “Company”) as of December 31, 2020, based on criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2020, based on criteria established in Internal Control—Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2020, of the Company and our report dated February 25, 2021, expressed an unqualified opinion on those financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
