We have custom-built large portions of our proprietary technology and operational platform to deliver the best experience for both our customers and suppliers. Our success has been built on a culture of data-driven decision-making, operational discipline and an unwavering focus on the customer. We believe that our internal control of our technology systems, which gives us the ability to update them often, is a competitive advantage.

Our team of over 3,000 engineers and data scientists has built a full set of technology solutions specific to the home goods market. Our storefront consists of a large set of tools and systems with which our customers directly interact, that are specifically tuned for shopping the home goods category by mixing lifestyle imagery with easy-to-use navigation tools and personalization features designed to increase customer conversion. We have designed operations software to deliver the reliable and consistent experience consumers desire, with proprietary software enhancing our performance in areas such as integration with our suppliers, our warehouse and logistics network and our customer service operation. Much of our advertising technology was internally developed, including campaign management and bidding algorithms for online advertising. This allows us to leverage our internal data and target customers efficiently across various channels. We also partner selectively with marketing partners where we find solutions that meet our marketing objectives and deliver a strong return on investment.

Much of the underlying infrastructure for storefront, operations and advertising technology is common across all of our sites and countries. We rely on a hybrid data infrastructure that integrates a physical data center network with a cloud-based solution forhave transitioned most of our data storage and processing. Ourprocessing systems from our physical data centers are highly secure, with wide geographic distribution and engineering resources to support high availability. These systems are monitored 24x7 by our network operations center for performance and security.a cloud-based solution.

OurWe use a variety of marketing and advertising efforts bringto drive customer engagement across all of our channels, strengthen and reinforce brand and product awareness, as well as attract new customers and encourage repeat customers to our sites and help us acquire their email addresses through various paid and non-paid advertising methods.purchases from existing customers. Our paid advertising efforts consist primarily of online channels, including search engine marketing, display advertising and paid social media, and to a lesser extent direct mail and television advertisements. Our non-paid advertising efforts include search engine optimization, non-paid social media, mobile "push"“push” notifications and email. Upon acquiring a customer or a potential customer's email address, we seek to increase their engagement with our sites and drive repeat

Our logistics network was built specifically for the home category, where items can be bulky, heavy and prone to damage. Historically, ourOur primary method of fulfillment wasis a drop-ship network where integration into our suppliers' back-end technology infrastructure allowedallows us to process an order and send itthe information directly to a supplier's warehouse. We would then arrange for shipment from the loading dock of the supplier's warehouse to the customer's home. Depending on the size of the package, the delivery would beis made either primarily through carriers such as FedEx, UPS, DHL, the U.S. Postal Servicefor our small parcel products, or third-party line haul trucking companies for our large parcel products and third-party last mile home delivery agents. Today, an increasing proportion

We have also been growing the percentage of our customer orders is beingthat are shipped from our CastleGate warehouses.warehouses over the last several years. This is facilitated by our ISCCastleGate Forwarding services, offering inbound freight, drayage and ocean services for suppliers sending products from Asia with direct delivery to CastleGate locations. The majority of large parcel items are delivered to the customer through our WDN, which includes consolidation centers, cross docks and last mile delivery facilities. For smaller items, we partner with carriers to handle the delivery to the customer. We believe that our proprietary logistics network has and will continue to help drive incremental sales by delighting our customers with faster delivery times and a better home delivery experience. Over time we believe this network will also lower our costs per order by reducing damage rates and leveraging economies of scale in transportation.

The market for online home goods and furniture is highly competitive, fragmented and rapidly changing. While we are primarily focused on the mass market, we compete across all segments of the home goods market. Our competition includes furniture stores, big box retailers, department stores, specialty retailers and online retailers and marketplaces in the U.S., Canada, the United Kingdom, Germany and Germany,Ireland, including:

We believe that the primary competitive factors in the mass market are vast selection, visually inspiring browsing, compelling merchandising, ease of product discovery, price, convenience, reliability, speed of fulfillment and customer service. We believe our technological and operational expertise allows us to provide our customers with a vast selection of goods, attractive price points, reliable and timely fulfillment, plus superior customer service and that the combination of these capabilities is what provides us with a sustainable competitive advantage.

At Wayfair, we believe strongly in our peoplepeople. Supporting our employees has always been central to our work and want to ensure eachwe believe that it is important that all employees feel welcome and every employee is empowered and positionedare able to bring their authentic selffull selves to work every day.

We believe we have a good relationship with our employees, which include 16,122includes approximately 14,400 employees, of which approximately 12,800 are full-time equivalent employeesequivalents, as of December 31, 2020.2023. Our reported headcount includes a substantial majority of employees impacted by the workforce reduction we announced in January 2024. The workforce reduction included approximately 1,650 employees, of which 1,200 are corporate employees, who will no longer be reflected in our headcount by the end of the first quarter of 2024. Additionally, we rely on independent contractors and temporary personnel to supplement our workforce, primarily in our logistics network. None of our employees are represented by a labor union or covered by a collective bargaining agreement.

WhileWayfair is committed to protecting our team members’ health and wellness. We continue to evolve our programs to support our employees’ health and wellness needs. We also provide benefits and resources to employees aimed at addressing stress, burnout and mental health and the COVID-19 outbreak has not hadpromotion of self-care. Maintaining a material adverse impactsafe work environment is also important to us, and our management team reaffirms our objectives each year to our frontline employees through our annual Commitment to Safety

We believe our intellectual property, including any trademarks, service marks, copyrights, domain names, patents, trade dress, trade secrets and proprietary technologies, is an important part of our business. We seek to protect our intellectual property by relying on federal, state and common law rights in the United States and other countries, as well as contractual restrictions. We generally enter into confidentiality and assignment of invention assignment agreements with employees and certain contractors and confidentiality agreements with other third parties, such as suppliers, in order to limit access to, and disclosure and use of, our confidential information and proprietary technology. In addition to these contractual arrangements, we also rely on a combination of trademarks, trade dress, domain names, copyrights, trade secrets and patents to help protect our other intellectual property.

Uncertainties in global economic conditions that are beyond our control have in the past impacted our business and may in the future materially adversely affect our business, results of operations, financial condition and operating results.

A downturn in the best interestseconomic environment can also lead to financial instability, increased credit and collectability risk on our receivables, the failure of our customers, employees,important partners, including suppliers, partners, stockholders and communities. We cannot predict with any certainty whether and to what degree the disruption caused by the COVID-19 outbreak and reactions thereto will continue, and we expect to face difficulty in accurately forecasting our financial condition and operational results.

Additionally, the growth of our business places significant demands on our operations, as well as our management and other employees. For example, we typically launch hundreds of promotional events across thousands of products each month on our sites via emails, "push"“push” notifications and personalized displays. These events require us to produce updates of our sites and emails to our customers on a daily basis with different products, photos and text. Any surge in online traffic and orders associated with such promotional activities places increased strain on our operations, including our logistics network, and may cause or exacerbate slowdowns or interruptions. The growth of our business may require significant additional resources to meet these daily requirements, which may not scale in a cost-effective manner or may negatively affect the quality of our sites and customer experience. Further, we have faced and may continue to face a number of challenges to our expansion into physical retail locations, including locating retail space with a cost and geographic profile that will allow us to operate in highly desirable shopping locations, hiring in-store talent and expanding our physical retail operations in a cost-effective manner. We have entered into and may continue to enter into long-term leases before we know whether our physical retail strategy or a particular geography will be successful. We are also required to manage relationships with a growing number of suppliers, customers and other third parties.parties across the world. Our information technology systems and our internal controls and procedures may not be adequate to support future growth of our supplier and employee base.

Our success depends on our ability to acquire and retain customers in a cost-effective manner. In order to expand our customer base, we must appeal to and acquire customers who have historically used other means of commerce to purchase home goods and may prefer alternatives to our offerings, such as traditional brick and mortar retailers, the websites of our competitors or our suppliers' own websites. We have made significant investments related to customer acquisition and expect to continue to spend significant amounts to acquire additional customers and to reactivate prior customers. Our paid advertising efforts consist primarily of television advertising, direct mail, catalog and print advertising, and online channels,channel advertising, including display advertising, paid search advertising, social media advertising, search engine optimization and comparison shopping engine advertising, television advertising, direct mail, catalog and print advertising. These efforts are expensive and may not result in the cost-effective acquisition of customers. Our marketing expenses have varied from period to period, and we expect this trend to continue as we test new channels and refine our marketing strategies. We may increase or decrease our marketing spend within a period, based on the degree of our achievement of intended results, which may result in increased or decreased customer engagement in any given period. We cannot assure you that the net profit from new or returning customers we acquire will ultimately exceed the cost of acquiring those customers. Additionally, actions by third parties to block or impose restrictions on the delivery of certain advertisements could also adversely impact our business. If we fail to deliver a quality shopping experience, or if consumers do not perceive the products we offer to be of high value and quality, we may not be able to acquire new customers or retain existing customers. If we are unable to acquire new customers or reactivate prior customers who purchase products in numbers sufficient to grow our business, we may not be able to generate the scale necessary to drive beneficial network effects with our suppliers or efficiencies in our logistics network, our net revenue may decrease, and our business, financial condition and operating results may be materially adversely affected.

We believe that many of our new customers originate from word-of-mouth and other non-paid referrals from existing customers. Therefore, we must ensure that our existing customers remain loyal to us in order to continue receiving those referrals. If our efforts to satisfy our existing customers are not successful, we may not be able to acquire new customers in sufficient numbers to continue to grow our business, or we may be required to incur significantly higher marketing expenses in order to acquire new customers.

Our ability to grow our business depends on our ability to retain our existing customer base and generate increased net revenue and repeat purchases from this customer base and maintain high levels of customer engagement. To do this, we must continue to provide our customers and potential customers with a unified, convenient, efficient and differentiated shopping experience by:

If we fail to increase net revenue per active customer, generate repeat purchases or maintain high levels of customer engagement, our growth prospects, operating results and financial condition could be materially adversely affected.

Maintaining and enhancing our brands is critical to expanding our base of customers and suppliers. Our ability to maintain and enhance our brandbrands depends largely on our ability to maintain customer confidence in our product and service offerings, including by maintaining product availability and delivering products on time and without damage. If customers do not have a satisfactory shopping experience, they may seek out alternative offerings from our competitors and may not return to our sites as often in the future, or at all. In addition, unfavorable publicity regarding, for example, our practices relating to privacy and data protection, employment matters, product quality or availability, poor customer service, delivery problems, competitive pressures, litigation or regulatory activity, could seriously harm our reputation. Such negative publicity could also could have an adverse effect on the size, engagement and loyalty of our customer base and result in decreased net revenue, which could adversely affect our business and financial results. A significant portion of our customers' brand experience also depends on third parties outside our control, including our suppliers, assembly and installation service providers and logistics providers such as FedEx, UPS, DHL, the U.S. Postal Service and other third-party delivery agents.providers. If these third parties do not meet our or our customers' expectations, our brands may suffer irreparable damage.

In addition, maintaining and enhancing theseour brands may require us to make substantial investments, and these investments may not be successful. If we fail to promote and maintain our brands, or if we incur excessive expenses in this effort, our business, operating results and financial condition may be materially adversely affected. We anticipate that, as our market becomes increasingly competitive, maintaining and enhancing our brands may become increasingly difficult and expensive. Maintaining and enhancing our brands will depend largely on our ability to provide high quality products to our customers and a reliable, trustworthy and profitable sales channel to our suppliers, which we may not be able to do successfully.

Customer complaints or negative publicity about our sites, products, delivery times, company practices, employees, customer data handling and security practices or customer support, especially on blogs, social media websites and our sites, could rapidly and severely diminish consumer use of our sites and consumer and supplier confidence in us and result in harm to our brands.brands and decreased revenue, whether or not the complaints and negative sentiment are based in fact. Further, the proliferation of social media may increase the likelihood, speed, and magnitude of such negative events.

Our business success depends to some extent on our ability to expand our customer offerings by launching new brands and services and by expanding our existing offerings into new geographies.geographic markets from time to time. For example, we recently launched Decorify in 2023, Wayfair.ie in Ireland in 2022 and the Kelly Clarkson Home Collection and Hykkon, a European Union flagship brand, and in 2016 we launched Wayfair.ca in Canada.2020. Launching new brands and services or expanding internationally is time-consuming, requires significant amounts of management time and resources, substantial upfront investments, including investments in marketing, information technology and additional personnel. Expanding our brands internationally is particularly challenging because it requires us to gain country-specific knowledge about consumers, regional competitors and local laws, construct catalogs specific to the country, build local logistics capabilities and customize portions of our technology for local markets. We may not be able to generate satisfactory net revenue from these efforts to offset these costs. Any lack of market acceptance of our efforts to launch new brands and services or to expand our existing offerings could have a material adverse effect on our business, prospects, financial condition and operating results. Further, as we continue to expand our fulfillment capability or add new businesses with different requirements, our logistics networks become increasingly complex and operating them becomes more challenging. There can be no assurance that we will be able to operate our networks effectively.

We have also entered and may continue to enter new markets or channels in which we have limited or no experience, which may not be successful or appealing to our customers. These activities may present new and difficult technological and logistical challenges, and resulting service disruptions, failures or other quality issues may cause customer dissatisfaction and harm our reputation and brand. Further, our current and potential competitors in new market segments may have greater brand recognition, financial resources, longer operating histories and larger customer bases than we do in these areas. As a result, we may not be successful enough in these newer areas to recoup our investments in them. If this occurs, our business, financial condition and operating results may be materially adversely affected.

Further, a failure to implement our expansion initiatives properly, or the adverse impact of political or economic risks in our costs of doing business internationally;

Because we generate net revenue in the local currencies of our international business, our financial results are impacted by fluctuations in currency exchange rates. The results of operations of our international business are exposed to currency exchange rate fluctuations as the financial results of the applicable subsidiaries are translated from the local currency to U.S. dollars for financial reporting purposes. Our consolidated financial statements are denominated in U.S. dollars and as a result fluctuations in currency exchange rates may adversely affect our results of operations or financial results. If the U.S. dollar weakens against foreign currencies, the translation of these foreign currency denominated net revenues or expenses will result in increased U.S. dollar denominated net revenues and expenses. Similarly, if the U.S. dollar strengthens against foreign currencies, particularly the euro,Euro, the British pound, or the Canadian dollar, our translation of foreign currency denominated net revenues or expenses will result in lower U.S. dollar denominated net revenues and expenses. Additionally, global events as well as geopolitical developments, including military conflicts in Ukraine and the Middle East, fluctuating commodity prices, trade tariff developments and inflation have caused, and may in the future cause, global economic uncertainty and uncertainty about the interest rate environment, which has recently and could continue to amplify the volatility of currency fluctuations. To date, we have not entered into any currency hedging contracts. As a result, we may not be able to effectively offset the adverse financial impacts that may result from unfavorable movements in foreign currency exchange rates, and therefore fluctuations in foreign exchange rates could significantly impact our financial results.

Prior to fiscal 2020, weWe have had a history of losses and negative cash flow and a resulting accumulated deficit of $1.9 billion as of December 31, 2020. Although we achieved profitability and positive cash flowflow. We incurred losses in fiscal 2020,years 2022 and 2023, and we can provide no assurance that we will be profitable in future quartersyears or achieve our goal of sustained profitability. Because the market for purchasing home goods online is rapidly evolving, and has not yet reached widespread adoption, it is difficult for us to predict our future operating

The satisfactory performance, reliability and availability of our sites, transaction processing systems, logistics network and technology infrastructure are critical to our reputation and our ability to acquire and retain customers, as well as maintain adequate customer service levels.

For example, if one of our data centerscloud provider fails or suffers an interruption or degradation of services, we could lose customer data and miss order fulfillment deadlines, which could harm our business. Our systems and operations, including our ability to fulfill customer orders through our logistics network, are also vulnerable to damage or interruption from inclement weather, fire, flood, power loss, telecommunications failure, terrorist attacks, labor disputes, cyber-attacks, data loss, acts of war, break-ins, other physical security threats, earthquake and similar events. In the event of a data center failure,system outage or degradation, the failover to another site or a back-up could take substantial time, during which time our sites could be completely shut down. Further, our back-up services may not effectively process spikes in demand, may process transactions more slowly and may not support all of our sites' functionality.

We use complex proprietary software in our technology infrastructure, which we seek to continually update and improve. We may not always be successful in executing these upgrades and improvements, and the operation of our systems may be subject to failure. In particular, we have in the past and may in the future experience slowdowns or interruptions in some or all of our sites when we are updating them, and new technologies or infrastructures may not be fully integrated with existing systems on a timely basis, or at all. Additionally, we have expanded our use of third-party services, including third-party "cloud"“cloud” computing services, and as a result, our technology infrastructure may be subject to slowdowns or interruptions as a result of integration with such services and/or failures by such third-parties, which are out of our control. Our net revenue primarily depends on the number of visitors who shop on our sites and the volume of orders we can handle. Unavailability of our sites or reduced order fulfillment performance would reduce the volume of goods sold and could also materially adversely affect consumer perception of our brand.

We may experience periodic system interruptions from time to time. In addition, continued growth in our transaction volume, as well as surges in online traffic and orders associated with promotional activities and seasonal trends in our business, or the COVID-19 outbreak, place additional demands on our technology platform and could cause or exacerbate slowdowns or interruptions. If there is a substantial increase in the volume of traffic on our sites or the number of orders placed by customers, we may be required to further expand and upgrade our technology, logistics network, transaction processing systems and network infrastructure. There can be no assurance that we will be able to accurately project the rate or timing of increases, if any, in the use of our sites or expand and upgrade our systems and infrastructure to accommodate such increases on a timely basis. In order to remain competitive, we must continue to enhance and improve the responsiveness, functionality and features of our sites, which is particularly challenging given the rapid rate at which new technologies, such as those related to artificial intelligence, customer preferences and expectations, and industry standards and practices are evolving in the e-commerce industry. Accordingly, we redesign and enhance various functions on our sites on a regular basis, and we may experience instability and performance issues as a result of these changes.

Any slowdown, interruption or performance failure of our sites and the underlying technology and logistics infrastructure could harm our business, reputation and our ability to acquire, retain and serve our customers, which could materially adversely affect our results of operations. Our disaster recovery plan may be inadequate, and our business interruption insurance may not be sufficient to compensate us for the losses that could occur.

We expect competition in e-commerce generally to continue to increase. We believe that our ability to compete successfully depends upon many factors both within and beyond our control, including:

ManySome of our current competitors have, and potential competitors may have, longer operating histories, greater brand recognition, larger fulfillment infrastructures, greater technical capabilities, faster and less costly shipping, lower prices, significantly greater financial, marketing and other resources and larger customer bases than we do. These factors may allow our competitors to derive greater net revenue and profits from their existing customer base, acquire customers at lower costs or respond more quickly than we can to new or emerging technologies and changes in consumer habits. These competitors may engage in more extensive research and development

If the online market for home goods does not continue to gain acceptance, a significant portion of our business may suffer. Our success will depend, in part, on our ability to attract consumers who have historically purchased home goods through traditional retailers. Furthermore, we may have to incur significantly higher and more sustained advertising and promotional expenditures in order to attract additional online consumers to our sites and convert them into purchasing customers.customers online. Specific factors that could impact consumers'consumers’ willingness to purchase home goods from us online, especially in markets where we do not have physical stores, include:

Some of the products we sell may expose us to product recalls, product liability and other claims and litigation (including class actions) or regulatory action relating to safety, personal injury, death or environmental or property damage. Some of our agreements with members of our supply chain may not indemnify us from product liability for a particular product, and some members of our supply chain may not have sufficient resources or insurance to satisfy their product liability and other indemnity and defense obligations. In addition, we are involved in lawsuits, claims and proceedings incident to the ordinary course of our business. Litigation is inherently unpredictable. Any claims against us, whether meritorious or not, could result in costly litigation that could adversely affect our business. Although we maintain liability insurance, we cannot be certain that our coverage will be adequate for liabilities actually incurred or that insurance will continue to be available to us on economically reasonable terms, or at all.

We depend on our ability to provide our customers with a wide range of products from qualified suppliers in a timely and efficient manner. Political and economic instability, global or regional adverse conditions, such as military conflicts, pandemics or other disease outbreaks or natural disasters, the financial stability or insolvency of our suppliers, suppliers'our suppliers’ ability to meet our code of conduct and other business standards, labor problems experienced by our suppliers, the availability or cost of raw materials, merchandise quality issues, currency exchange rates, trade tariff developments, imposition of anti-dumping and countervailing duties or other trade-related sanctions, transport availability and cost, including import-related taxes, transport security, labor inflation and other factors relating to our suppliers are beyond our control. As anFor example, while we experienced increased sales and order activity at times during the COVID-19 outbreak has and may continue to adversely impact supplier facilities and operationspandemic, the pandemic significantly disrupted the global supply chain, including many of our suppliers due to extended holidays, factory closures, raw material and labor inflation and risks of labor shortages, among other things,things. Additionally, although we do not have direct operations in the Middle East, the ongoing conflict between Israel and Hamas and the escalating tensions in the region may impact our supply chain. Any ongoing or future disruptions could materially and adversely affect our suppliers’ ability to provide products in a timely manner, or at all, which may materially and adversely affect our business, financial condition and operating results.

Our agreements with most of our suppliers do not provide for the long-term availability or exclusivity of merchandise or the continuation of particular pricing practices, nor do they usually restrict such suppliers from selling products to other buyers.practices. There can be no assurance that our current suppliers will continue to seek to sell us products on current terms or that we will be able to establish new or otherwise extend current supply relationships to ensure product acquisitions in a timely and efficient manner andavailability on acceptable commercial terms. Our ability to develop and maintain relationships with reputable suppliers and offer high quality merchandise to our customers is critical to our success. If we are unable to develop and maintain relationships with suppliers that would allow us to offer a sufficient amount and variety of quality merchandise on acceptable commercial terms, our ability to satisfy our customers'customers’ needs, and therefore our long-term growth prospects, would be materially adversely affected.

Further, we rely on our suppliers’ representations of product quality, safety and compliance with applicable laws and standards. If our suppliers or other vendors violate our agreements, applicable laws or regulations, or implement practices regarded as fraudulent, unethical, unsafe, or hazardous to the environment, it could damageharm our business, reputation and negatively affectbrands and our operating results.results may be negatively affected. Further, concerns regarding the safety and quality of products provided by our suppliers could cause our customers to avoid purchasing those products from us, or avoid purchasing products from us altogether, even if the basis for the concern is outside our control. As such, any issue, or perceived issue, regarding the quality and safety of any items we sell, regardless of the cause, could adversely affect our brand, reputation, operations and financial results. We are also subject to risks of fraud from our suppliers.

We also are unable to predict whether any of the countries in which our suppliers'suppliers’ products are currently manufactured or may be manufactured in the future will be subject to new, different, or additional trade restrictions imposed by the U.S. or foreign governments or the likelihood, type or effect of any such restrictions. Any event causing a disruption or delay of imports from suppliers with international manufacturing operations, including the imposition of additional import restrictions, restrictions on the transfer of funds or increased tariffs or quotas, could increase the cost or reduce the supply of merchandise available to our customers and materially adversely affect our financial performance as well as our reputation and brand. Furthermore, some or all of our suppliers'suppliers’ foreign operations may be adversely affected by political and financial instability, including, without limitation, the military conflicts in Ukraine and the Middle East, as well as other unexpected events, including public health crises resulting in the disruption of trade from exporting countries, restrictions on the transfer of funds or other trade disruptions.

In addition, with respect to our business with foreign suppliers, particularly with respect tofor our international sites, we have in the past and may in the future be affected by changes in the value of the U.S. dollar relative to other foreign currencies. For example, any movement by any other foreign currency against the U.S. dollar may result in higher costs to us for those goods. Declines in foreign currencies and currency exchange rates might negatively affect the profitability and business prospects of one or more of our foreign suppliers. This, in turn, mighthas caused and may in the future cause such foreign suppliers to demand higher prices for merchandise in their effort to offset any lost profits associated with any currency devaluation, delay merchandise shipments, or discontinue selling to us altogether, any of which could ultimately reduce our sales or increase our costs.

We have relationships with over 16,00020 thousand suppliers. Our agreements with suppliers are generally terminable at will by either party upon short notice. If we do not maintain our existing relationships or build new relationships with suppliers on acceptable commercial terms, we may not be able to maintain a broad selection of merchandise, and our business and prospects would suffer severely.

In order to attract quality suppliers to our platform, we must:

If we are unable to provide our suppliers with a compelling return on investment and an ability to increase their sales, we may be unable to maintain and/or expand our supplier network, which would negatively impact our business.

As part of offering our suppliers'suppliers’ products for sale, on our sites, suppliers are often responsible for conducting a number of traditional retail operations with respect to their respective products, including maintaining inventory, and preparing merchandise for shipment to our customers.customers, and, in some cases, delivering products on our behalf. In these instances, we may be unable to ensure that suppliers will perform these services to our or our customers' satisfaction in a manner that provides our customer with a unified brand experience or on commercially reasonable terms. If our customers become dissatisfied with the services provided by our suppliers, our business, reputation and brands could suffer.

The Sarbanes-Oxley Act of 2002 requires that we maintain effective internal control over financial reporting and disclosure controls and procedures. In particular, we must perform system and process evaluation, document our controls and perform testing of our key control over financial reporting to allow management and our independent public accounting firm to report on the effectiveness of our internal control over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act. Our testing, or the subsequent testing by our independent public accounting firm, may reveal deficiencies in our internal control over financial reporting that are deemed to be material weaknesses. If we are not able to comply with the requirements of Section 404 in a timely manner, or if we or our accounting firm identify deficiencies in our internal control over financial reporting that are deemed to be material weaknesses, the market price of our stock would likely decline and we could be subject to lawsuits, sanctions or investigations by regulatory authorities, including SEC enforcement actions, and we could be required to restate our financial results, any of which would require additional financial and management resources.

We continue to invest in more robust technology and resources to manage those reporting requirements. Implementing the appropriate changes to our internal controls may distract our officers and employees, result in substantial costs and require significant time to complete. Any difficulties or delays in implementing these controls could impact our ability to timely report our financial results. For these reasons, we may encounter difficulties in the timely and accurate reporting of our financial results, which would impact our ability to provide our investors with information in a timely manner. As a result, our investors could lose confidence in our reported financial information, and our stock price could decline.

In addition, any such changes do not guarantee that we will be effective in maintaining the adequacy of our internal controls, and any failure to maintain that adequacy could prevent us from accurately reporting our financial results.

Our financial and operating results are inherently uncertain and difficult to forecast because they generally depend on the volume, timing and type of orders we receive, all of which are uncertain. In particular, we cannot be sure that our historical growth rates, trends and other key performance metrics are meaningful predictors of future growth. In addition, our mix of product offerings is highly variable from day-to-day and quarter-to-quarter. This variability makes it difficult to predict sales and could result in significant fluctuations in our net revenue from period-to-period. Our business is also affected by general economic and business conditions globally.globally, including inflation, slower growth or recession, new or increased tariffs and other changes to fiscal and monetary policy, tighter credit, higher interest rates, high unemployment, consumer confidence in the economy, consumer debt levels, energy prices, and currency fluctuations. Additionally, the volatile and uncertain macroeconomic environment that we have experienced since the onset of the COVID-19 pandemic has likely reduced, and may continue to reduce, our ability to forecast our future financial and operating results. As a result, forecasted financial and operating results may differ materially from actual results, which couldmay materially adversely affect our financial condition and stock price. For example, if certain of our assumptions or estimates prove to be wrong, we may spend more than we anticipate acquiring and retaining customers or may generate less net revenue per active customer than anticipated, which could cause us to miss our earnings guidance or negatively impact the results we report, either of which could negatively impact our stock price.

Historically, we have experienced surges in online traffic and orders associated with promotional activities and seasonal trends. This activity may place additional demands on our technology systems and logistics network and could cause or exacerbate slowdowns or interruptions. Any such system, site or service interruptions could prevent us from efficiently receiving or fulfilling orders, which may reduce the volume or quality of goods or services we sell and may cause customer dissatisfaction and harm our reputation and brand.

The number of people who access the Internet through devices other than personal computers, including mobile phones, smartphones, smartwatches, handheld computers such as notebooks and tablets, video game consoles and television set-top devices, has increased dramatically in the past few years. We continually upgrade existing technologies and business applications to keep pace with these rapidly changing and continuously evolving technologies, and we may be required to implement new technologies, such as those related to artificial intelligence, or business applications in the future. The implementation of these upgrades and changes requires significant investments and as new devices, operating systems and platforms are released, it is difficult to predict requirements or the problems we may encounter in developing applications for these alternative devices, operating systems and platforms. Additionally, we may need to devote significant resources to the support and maintenance of such applications once created. Our results of operations may be affected by the timing, effectiveness and costs associated with the successful implementation of any upgrades or changes to our systems and infrastructure to accommodate such alternative devices, operating systems and platforms. Further, in the event that it is more difficult or less compelling for our customers to buy products from us on their mobile or other devices, or if our customers choose not to buy products from us on such devices or to use mobile or other products that do not

We allow our customers to return products, subject to our return policy. If merchandise returns are significant, our business, prospects, financial condition and results of operations could be harmed. Further, we modify our policies relating to returns from time to time, which may result in customer dissatisfaction or an increase in the number of product returns. Many of our products are large and require special handling and delivery. From time to time our products are damaged in transit, which can increase return rates and harm our brand.

Our business is highly dependent upon email and other messaging services, including our mobile application, for promoting our sites and products. Daily promotions offered through emails and other messages sent by us, or on our behalf by our vendors, generate a significant portion of our net revenue. We provide daily emails and "push" communications to customers and other visitors informing them of what is available for purchase on our sites that day, and we believe these messages are an important part of our customer experience and help generate a substantial portion of our net revenue.operations strategy. If we are unable to successfully deliver emails or other messages to our subscribers, or if subscribers decline to open our emails or other messages, our net revenue and profitability would be materially adversely affected. Changes in how webmail applications organize and prioritize email may also reduce the number of subscribers opening our emails. For example, Google's Gmail service has a feature that organizes incoming emails into categories and such categorization or similar inbox organizational features may result in our emails being delivered in a less prominent location in a subscriber's inbox or viewed as "spam" by our subscribers and may reduce the likelihood of that subscriber opening our emails. Actions by third parties to block, impose restrictions on or charge for the delivery of emails or other messages could also adversely impact our business. From time to time, Internet service providers or other third parties may block bulk email transmissions or otherwise experience technical difficulties that result in our inability to successfully deliver emails or other messages to third parties. Changes in the laws or regulations that limit our ability to send such communications or impose additional requirements upon us in connection with sending such communications would also materially adversely impact our business. Our use of email and other messaging services to send communications about our sites or other matters may also result in legal claims against us, which may cause us increased expenses, and if successful might result in fines and orders with costly reporting and compliance obligations or might limit or prohibit our ability to send emails or other messages. We also rely on social networking messaging services to send communications and to encourage customers to send communications. Changes to the terms of these social networking services to limit promotional communications, any restrictions that would limit our ability or our customers' ability to send communications through their services, disruptions or downtime experienced by these social networking services or decline in the use of or engagement with social networking services by customers and potential customers could materially adversely affect our business, financial condition and operating results.

We accept payments using a variety of methods, including credit card, debit card, PayPal,electronic and mobile payment technologies, credit accounts (including promotional financing), installment loans, lease to own plans, gift cards and customer invoicing. We rely on third parties to provide many of these payment methods and payment processing services, including certain Wayfair-branded programs and promotional financing. AsIf we offer new payment options to consumers, we may be subject to additional regulations, compliance requirements and fraud. Additionally, changes to existing laws and regulations or their interpretation, or the adoption of new laws or regulations could require mandatory changes to our payment options. 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. We also offer private label and/or co-branded credit card programs, which could adversely

We occasionally receive orders placed with fraudulent credit card data. We have in the past, and may in the future, suffer losses as a result of orders placed with fraudulent credit card data even if the associated financial institution approved payment of

As part of our business strategy, we may acquire other companies, businesses or assets. However, we may not be able to find suitable acquisition candidates, and we may not be able to complete acquisitions on favorable terms, if at all. Acquisitions involve numerous risks, any of which could harm our business, including: difficulties in integrating the technologies, operations, existing contracts and personnel of an acquired company; difficulties in supporting and transitioning customers and suppliers, if any, of an acquired company; diversion of financial and management resources from existing operations or alternative acquisition opportunities; failure to realize the anticipated benefits or synergies of a transaction; failure to identify all of the problems, liabilities or other shortcomings or challenges of an acquired company or technology, including issues related to intellectual property, regulatory compliance practices, liabilities related to data security and privacy of customer data, the acquired company's internal controls over financial reporting, including revenue recognition or other accounting practices; employee or customer issues; risks of entering new markets in which we have limited or no experience; potential loss of senior management or other key employees, customers and suppliers from either our current business or an acquired company's business; inability to generate sufficient net revenue to offset acquisition costs; additional costs or equity dilution associated with funding the acquisition; and possible write-offs or impairment charges relating to acquired businesses, and these liabilities may be greater than the warranty and indemnity limitations we negotiate.

In addition, our investments in properties may not be fully realized. We continually review our operations and facilities in an effort to reduce costs and increase efficiencies. For strategic or other operational reasons, we may decide to consolidate or co-locate certain aspects of our business operations or dispose of one or more of our properties. For example, we have increasingly moved to virtualize certain customer service centers. If we decide to fully or partially vacate a leased property, we may incur significant costs, including facility closing costs, employee separation and retention expenses, lease termination fees, rent expense in excess of sublease income, impairment charges for right-of-use ("ROU"(“ROU”) assets and leasehold improvements and accelerated depreciation of assets. Any of these events may materially adversely affect our business, financial condition and operating results.

We regard our customer lists, trademarks, domain names, copyrights, patents, trade dress, trade secrets, proprietary technology and similar intellectual property as critical to our success, and we rely on a combination of trademark, copyright and patent law, trade dress, trade secret protection, agreements, and other methods together with the diligence our employees and others to protect our proprietary rights. We might not be able to obtain broad protection in the U.S. or internationally for all of our intellectual property, and we might not be able to obtain effective intellectual property protection in every country in which we sell products or perform services. For example, we are the registrant of marks for our brands in numerous jurisdictions and of the Internet domain name for the websites of Wayfair.com, Wayfair.ca, Wayfair.co.uk, Wayfair.de and Wayfair.ie and our other sites, as well as various related domain names. However, we have not registered our marks or domain names in all major international jurisdictions and may not be able to register or use such domain names in all of the countries in which we currently or intend to conduct business. Further, we might not be able to prevent third parties from registering, using or retaining domain names that interfere with our consumer communications or infringe or otherwise decrease the value of our marks, domain names and other proprietary rights.

The protection of our intellectual property rights may require the expenditure of significant financial, managerial and operational resources. We have in the past and may in the future initiate claims or litigation against others for infringement, misappropriation or violation of our intellectual property rights or proprietary rights or to establish the validity of such rights. Any litigation, whether or not it is resolved in our favor, could result in significant expense to us and divert the efforts of our technical and management personnel, which may materially adversely affect our business, financial condition and operating results. 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, and we may not be able to broadly enforce all of our trademarks or patents. Any of our patents, marks or other intellectual property rights may be challenged by others or invalidated through administrative process or litigation. Our patent and trademark applications may never be granted. Additionally, the process of obtaining intellectual property protections is expensive and time-consuming, and we may not be able to pursue all necessary or desirable actions at a reasonable cost or in a timely manner. Even if issued, there can be no assurance that these protections will adequately safeguard our intellectual property, as the legal standards relating to the validity, enforceability and scope of protection of patent and other intellectual property rights are uncertain. We also cannot be certain that others will not independently develop or otherwise acquire equivalent or superior technology or intellectual property rights. We may also be exposed to claims from third parties claiming infringement of their intellectual property rights, demanding the release or license of open source software or derivative works that we developed using such software (which could include our proprietary code) or otherwise seeking to enforce the terms of the applicable open source license. These claims could result in litigation and could require us to purchase a costly license, publicly release the affected portions of our source code, be limited in or cease using the implicated software unless and until we can re-engineer such software to avoid infringement or change the use of the implicated open source software.

The e-commerce industry is characterized by vigorous protection and pursuit of intellectual property rights, which has resulted in protracted and expensive litigation for many companies. We are subject to claims and litigation by third parties that we infringe their intellectual property rights, and we expect additional claims and litigation with respect to infringement to occur in the future. The costs of supporting such litigation and disputes are considerable, and there can be no assurances that favorable outcomes will be obtained. As our business expands and the number of competitors in our market increases and overlaps occur, we expect that infringement claims may increase in number and significance. Any claims or proceedings against us, whether meritorious or not, could be time-consuming, result in considerable litigation costs, require significant amounts of management time or result in the diversion of significant operational resources, any of which could materially adversely affect our business, financial condition and operating results.

Legal claims regarding intellectual property rights are subject to inherent uncertainties due to the oftentimes complex issues involved, and we cannot be certain that we will be successful in defending ourselves against such claims. In addition, some of our larger competitors have extensive portfolios of issued patents. Many potential litigants, including patent holding companies, have the ability to dedicate substantially greater resources to enforce their intellectual property rights and to defend claims that may be brought against them. Furthermore, a successful claimant could secure a judgment that requires us to pay substantial damages or prevents us from conducting our business as we have historically done or may desire to do in the future. We might also be required to seek a license and pay royalties for the use of such intellectual property, which may not be available on commercially acceptable terms, or at all. Alternatively, we may be required to develop non-infringing technology or intellectual property, which could require significant effort and expense and may ultimately not be successful.

We have received in the past, and we may receive in the future, communications alleging that certain items posted on or sold through our sites violate third-party copyrights, designs, marks and trade names or other intellectual property rights or other

Such claims, whether or not meritorious, may result in the expenditure of significant financial, managerial and operational 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 violated 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.

From time to time, we are subject to litigation or claims that could negatively affect our business operations and financial position. As we have grown, we have seen a rise in the number of litigation matters against us. These matters have included intellectual property claims, employment related litigation, as well as consumer and securities class actions, each of which are typically expensive to defend. Litigation disputes could cause us to incur unforeseen expenses, result in site unavailability, service disruptions and otherwise occupy a significant amount of our management's time and attention, any of which could negatively affect our business operations and financial position. We also from time to time receive inquiries and subpoenas and other types of information requests from government authorities and we may become subject to related claims and other actions related to our business activities. While the ultimate outcome of investigations, inquiries, information requests and related legal proceedings is difficult to predict, such matters can be expensive, time-consuming and distracting, and adverse resolutions or settlements of those matters may result in, among other things, modification of our business practices, reputational harm or costs and significant payments, any of which could negatively affect our business operations and financial position.

In August 2020, the Board authorized a stock repurchase program of up to $700 million of our Class A common stock in the open market, through privately negotiated transactions, or otherwise, including pursuant to a Rule 10b5-1 plan (the “2020 Repurchase Program”), which does not have an expiration date and replaced our previous $200 million. On August 10, 2021, the Board authorized a new $1.0 billion stock repurchase authorization approved byprogram on the Board in 2018, which was terminated simultaneously.same terms (the “2021 Repurchase Program” together with the 2020 Repurchase Program, the “Repurchase Programs”). Wayfair will begin repurchasing shares under the 2021 Repurchase Program upon the completion of the 2020 Repurchase Program. Although the Board has authorized the 2020 Repurchase Program,Programs, the program doesprograms do not obligate us to repurchase any specific dollar amount or to acquire any specific number of shares. WeThe amount, timing, and purchases under our stock repurchase program, if any, are influenced by many factors and may fluctuate based on our operating results, cash flows, and priorities for the use of cash, the market price of our common stock, and our possession of potentially material nonpublic information. Even if our Repurchase Programs are fully implemented, we cannot guarantee that the 2020 Repurchase ProgramPrograms will be fully consummated or that itthe programs will enhance long-term stockholder value. The programprograms could affect the trading price of our Class A common stock and increase volatility, and any announcement of a termination of thiseither program may result in a decrease in the trading price of our Class A common stock. In addition, this programthe amount, timing, and execution of our Repurchase Programs may fluctuate based on our priorities for the use of cash for other purposes, and because of changes in cash flows, tax laws, and the market price of our Class A common stock, the Repurchase Programs could diminish our cash reserves.

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, e-commerce or mobile commerce. These regulations and laws may involve taxes, tariffs, privacy and data security, anti-spam, content protection, artificial intelligence, electronic contracts and communications, consumer protection, Internet neutrality and gift cards. It is not clear how existing laws governing issues such as property ownership, sales and other taxes and consumer privacy apply to the Internet as the vast majority of these laws were adopted prior to the advent of the Internet and do not contemplate or address the unique issues raised by the Internet or e-commerce. It is possible that general business regulations and laws, or those specifically governing the Internet or e-commerce, may be interpreted and applied in a manner that is inconsistent from one jurisdiction to another and may conflict with other rules or our practices. We cannot be sure that our practices have complied, comply or will comply fully with all such laws and regulations. Any failure, or perceived failure, by us to comply with any of these laws or regulations could result in damage to our reputation, a loss in business and proceedings or actions against us by governmental entities or others. Any such proceeding or action could hurt our reputation, force us to spend significant amounts in defense of these proceedings, distract our management, increase our costs of doing business, decrease the use of our sites by consumers and suppliers and may result in the imposition of monetary liability. We may also be contractually liable to indemnify and hold harmless third parties from the costs or consequences of non-compliance with any such laws or regulations. In addition, it is possible that governments of one or more countries may seek to censor content available on our sites or may even attempt to completely block access to our sites. Adverse

Due to the global nature of the Internet, it is possible that various states or foreign countries might attempt to impose additional or new regulation on our business or levy additional or new 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 e-commerce and digital services. New or revised international, federal, state or local tax regulations or court decisions may subject us or our customers to additional sales, income and other taxes. For example, on June 21, 2018, the U.S. Supreme Court rendered a 5-4 majorityCourt's decision in South Dakota v. Wayfair, Inc., 17-494 removed a significant impediment to the enactment of laws imposing sales tax collection obligations on out-of-state e-commerce companies. After the Wayfair decision, several U.S. states imposed an economic presence standard with respect to the imposition of taxes. These new rules often have uncertainty with respect to the level of activity necessary to cause a taxable presence for taxpayers within the state. A successful assertion by one or more states requiring us to collect sales taxes where the Court held, among other things, thatwe currently do not, or to collect additional sales taxes in a state may require an out-of-state seller with no physical presence in the statetowhich we currently collect them, could result in substantial tax liabilities (including penalties and remit sales taxes on goods the seller

Our Charter provides that, unless we consent in writing to the selection of an alternative forum, the sole and exclusive forum for any (i) derivative action or proceeding brought on behalf of Wayfair; (ii) action asserting a claim for or based on a breach of a fiduciary duty owed by any director, officer or other employee of Wayfair to Wayfair or Wayfair’s stockholders; (iii) action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law (“DGCL”), the Charter, or the Company’s Amended and Restated Bylaws; or (iv) action asserting a claim that is governed by the internal affairs doctrine of the State of Delaware, in each case, will be the Delaware Court of Chancery located within the State of Delaware. These choice of forum provisions may increase costs to bring a claim, discourage claims or limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with the Company or the Wayfair’s directors, officers or other employees, which may discourage such lawsuits against the Wayfair or the Wayfair’s directors, officers and other employees. Alternatively, if a court were to find the choice-of- forum provisions contained in the Charter to be inapplicable or unenforceable in an action, we may incur could limit our operating flexibility and adversely affect our financial condition.

Future transfers by holders of Class B common stock will generally result in those shares converting on a 1:1 basis to Class A common stock, which will have the effect, over time, of increasing the relative voting power of those holders of Class B common stock who retain their shares in the long-term, which may include our executive officers.

We believe our Class A common stock has been the subject of significant short selling efforts by certain market participants. Short sales are transactions in which a market participant sells a security that it does not own. To complete the transaction, the market participant must borrow the security to make delivery to the buyer. The market participant is then obligated to replace the security borrowed by purchasing the security at the market price at the time of required replacement. If the price at the time of replacement is lower than the price at which the security was originally sold by the market participant, then the market participant will realize a gain on the transaction. Thus, it is in the market participant’s interest for the market price of the underlying security to decline as much as possible during the period prior to the time of replacement. Short selling may negatively affect the value of our stock to the detriment of our stockholders.

In addition, market participants with disclosed short positions in our stock have published, and may in the future continue to publish, negative information regarding us that we believe is inaccurate and misleading.us. We believe that the publication of this negative information may in the future lead to downward pressure on the price of our stock.

In connection with the issuance of each series of Non-Accreting Notes, we entered into capped calls with certain financial institutions, which we refer to as the option counterparties. The capped calls are expected generally to reduce the potential dilution upon conversion of the Notes and/or offset any cash payments we are required to make in excess of the principal amount of converted Notes, as the case may be, with such reduction and/or offset subject to a cap. From time to time, the option counterparties or their respective affiliates may modify their hedge positions by entering into or unwinding various derivative transactions with respect to our Class A common stock and/or purchasing or selling our Class A common stock or other securities of ours in secondary market transactions. This activity could cause a decrease in the market price of our Class A common stock.

In addition, the option counterparties are financial institutions, and we will be subject to the risk that one or more of the option counterparties may default or otherwise fail to perform, or may exercise certain rights to terminate, their obligations under the capped calls. Our exposure to the credit risk of the option counterparties will not be secured by any collateral. If an option counterparty becomes subject to insolvency proceedings, we will become an unsecured creditor in those proceedings with a claim equal to our exposure at the time under such transaction. Our exposure will depend on many factors but, generally, our exposure will increase if the market price or the volatility of our Class A common stock increases. In addition, upon a default or other failure to perform, or a termination of obligations, by an option counterparty, we may suffer more dilution than we currently anticipate with respect to our Class A common stock. We can provide no assurances as to the financial stability or viability of the option counterparties.

The trading market for our Class A common stock depends in part on the research and reports that securities or industry analysts publish about us or our business, our market and our competitors. We do not have any control over these analysts. If one or more of the analysts who cover us downgrade our shares or change their opinion of our shares, our share price would likely decline. If one or more of these analysts cease coverage of our company or fail 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.

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. Our certificate of incorporation and bylaws include provisions that:

These provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of the Board, which is responsible for appointing the members of our management. In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which generally prohibits a Delaware corporation from engaging in any of a broad range of business combinations with any holder of at least 15% of our capital stock for a period of three years following the date on which the stockholder became a 15% stockholder.
