Summary of our risk factors
Our business is subject to numerous risks that you should be aware of before making an investment decision. These risks are described more fully in "Item 3: Key information - D. Risk factors". These risks include, among others:
Risks related to the general economic and geopolitical environment, the travel industry and our business
We may not be able to grow our revenue in future periods, or at rates deemed sufficient by the market without reducing our profits or incurring losses.
The COVID-19 pandemic appears to have accelerated long-term changes to industry structure: Google has continued to expand its presence in the online travel industry and competition has increased more generally, while the number of first-time users of online travel services continues to decline.
The global economic outlook has worsened significantly, with higher interest rates and increased inflation negatively impacting consumer discretionary spending, which may reduce demand for our services.
Any change in the global geopolitical environment, including any escalation or unexpected change in circumstances in the ongoing military action between Russia and Ukraine, may have a material adverse effect on our business, results of operations, financial condition and prospects.
We derive a large portion of our revenue from a relatively small number of advertisers, and we relied on one advertiser for approximately half of our Referral Revenue in 2022. Any reduction in spending or any change in the bidding strategies by any of these advertisers could harm our business and negatively affect our financial condition and results of operations.
We cannot reliably predict our advertisers' future advertising spend or CPC levels or other strategic goals they hope to achieve through changes in bidding on our marketplace and, as a result, it is difficult for us to forecast advertiser demand, especially since our advertisers can and often do change their CPC bidding levels with little or no notice to us.
As a result of the change in the macroeconomic outlook, we have experienced and may in the future record impairments of intangible assets and goodwill.
Because we almost completely ceased television advertising in 2020, which resumed only at reduced levels in 2021 and 2022, we do not expect our past advertising campaigns to contribute the direct traffic to our platform that we had prior to the COVID-19 pandemic. This is expected to hinder our ability to grow our revenue, which could continue to harm our business and negatively affect our financial condition and results of operations.
Increasing competition in our industry could result in a loss of market share and higher traffic acquisition costs or reduce the value of our services to users and a loss of users, which would adversely affect our business, results of operations, financial condition and prospects.
We rely on search engines, particularly Google, to drive a substantial amount of traffic to our platform. If Google continues to promote its own products and services that compete directly with our accommodation search at the expense of traditional keyword auctions and organic search, our business, financial performance and prospects may be negatively impacted.
If we do not innovate and provide tools and services that are sufficiently useful to users and advertisers, we may not remain competitive, and our revenue and results of operations could suffer.
Several of our product features depend, in part, on our relationship with third parties to provide us with content and services.
3





Legal and regulatory risks
We are involved in various legal proceedings and may experience unfavorable outcomes, which could adversely affect our reputation, business and financial condition.
Regulators' continued focus on the consumer-facing business practices of online travel companies may adversely affect our business, financial performance, results of operations or business growth.
We process, store and use user and employee personal data, which entails reputational, litigation and liability risks associated to any actual or perceived potential failure to comply with relevant legal obligations, which are constantly evolving.
Operational risks
The competition for highly skilled personnel, including senior management and technology professionals is intense. If we are unable to retain or motivate key personnel or hire, retain, and motivate qualified personnel, especially as the broader job market undergoes structural changes that increase our costs, our business would be harmed.
We are dependent upon the quality of traffic in our network to provide value to our advertisers, and any failure in our ability to deliver quality traffic and/or the metrics to demonstrate the value of the traffic could have a material and adverse impact on the value of our websites to our advertisers and adversely affect our revenue.
We rely on assumptions, estimates and data to make decisions about our business, and any inaccuracies in, or misinterpretation of, such information could negatively impact our business.
We may experience difficulties in implementing new business and financial systems.
Increased computer circumvention capabilities could result in security breaches in our information systems, which may significantly harm our business.
Any significant disruption in service on our websites and apps or in our computer systems, most of which are currently hosted by third-party providers, could damage our reputation and result in a loss of users, which would harm our business and results of operations.
We rely on information technology to operate our business and maintain our competitiveness, and any failure to invest in and adapt to technological developments and industry trends could harm our business.
Our brand is subject to reputational risks and impairment.
Risks related to our ongoing relationship with our shareholders
Expedia Group controls our company and has the ability to control the direction of our business.
Expedia Group’s interests may conflict with our interests, the interests of the Founders and the interests of our shareholders, and conflicts of interest among Expedia Group, the Founders and us could be resolved in a manner unfavorable to us and our shareholders.

D. Risk factors
Our business faces significant risks. You should carefully consider all of the information set forth in this annual report and in our other filings with the United States Securities and Exchange Commission, or the SEC, including the following risks that we face and that are faced by our industry. Our business, financial condition or results of operations could be materially adversely affected by any of these risks. This annual report also contains forward-looking statements that involve risks and uncertainties. Our results could materially differ from those anticipated in these forward-looking statements as a result of certain factors including the risks described below and elsewhere in this annual report and our other SEC filings. See “Special note regarding forward-looking statements” above. For a summary of these risk factors, see "Summary of our risk factors" above.
Risks related to the general economic and geopolitical environment, the travel industry and our business
We may not be able to grow our revenue in future periods, or at rates deemed sufficient by the market without reducing our profits or incurring losses.
After having experienced a significant reduction in revenue in 2020 as a result of the COVID-19 pandemic, our major advertisers resumed marketing activities in 2021 and 2022 on our platform but at levels significantly below those in 2019. We believe the degree to which we are able to grow our revenue without reducing our profits or incurring losses will be an important factor in how our business will be valued by the market. We may not be able to increase our revenue in future periods without reducing our profits or incurring losses, and our revenue may decline even if we are unprofitable. We continue to be impacted by a number of factors that may continue to adversely affect our future financial performance:
The COVID-19 pandemic appears to have accelerated long-term changes to industry structure: Google has continued to expand its presence in the online travel industry and competition has increased more generally, while the number of first-time users of online travel services continues to decline, changing the type (and potential attractiveness) of users we are able to refer to our largest online travel agency or "OTA" advertisers. In addition, the COVID-19 pandemic caused several of our smaller advertisers to file for insolvency, and the online travel industry may experience further consolidation in the future, resulting in fewer offers available on our platform and less competition on our marketplace.
The global economic outlook has worsened significantly, with higher interest rates and increased inflation negatively impacting consumer discretionary spending, which may reduce demand for our services. Travel, including the booking of accommodation, is dependent on personal and business discretionary spending levels, which are directly affected by perceived or actual adverse economic conditions. Our results of operations and financial prospects continue to be significantly dependent upon the economic health of our users and the prosperity and solvency of the OTAs, hotel chains and independent hotels that have relationships with us.
Any change in the global geopolitical environment, including any escalation or unexpected change in circumstances in the ongoing military action between Russia and Ukraine, may exacerbate the negative impact of the factors above on our business.
We expect the variability, cyclicality and seasonality in our business to continue to be more pronounced or at least more apparent than had been the case in recent periods as travel demand increased following the COVID-19 lockdowns. This may result in greater fluctuations of our revenue, cash flows, results of operations and other key performance measures from period to period or among segments, and may affect the price of our American Depositary Shares (ADSs) and increase their trading volatility.

We derive a large portion of our revenue from a relatively small number of advertisers, and we relied on one advertiser for approximately half of our Referral Revenue in 2022. Any reduction in spending or any change in the bidding strategies by any of these advertisers could harm our business and negatively affect our financial condition and results of operations.
Our "cost-per-click," or CPC, pricing for click-based advertising depends, in part, on competition among advertisers on our marketplace, with advertisers that pay higher CPCs generally receiving better advertising placement and more referrals from us. We continue to generate the great majority of our revenue from our largest OTA advertisers, including, to an increasing extent since the start of the pandemic, brands affiliated with Booking Holdings, such as Booking.com and Agoda, and those affiliated with our majority shareholder, Expedia Group, such as Brand Expedia and Hotels.com. The loss of any of our major advertisers, on some or all of our platforms, or a further reduction in the amount they spend, or a further concentration in Advertising Spend by one advertiser could result in significant decreases in our revenue and profit or negative impacts on our liquidity position.
Our ability to grow and maintain revenue from our advertisers is dependent to a significant extent on our ability to generate referrals, customers, bookings or revenue and profit for our advertisers on a basis they deem to be cost-effective. Any reduction in the value that we deliver to our advertisers or our ability to match the value delivered by our competitors may negatively affect CPC bids on our marketplace. Our advertisers’ spend on our platforms may also be adversely affected by other factors such as a weakening of their own financial or business conditions or external economic effects.
Even if we improve our product and deliver value to our advertisers, the fact that a significant portion of our revenue is generated from brands affiliated with Booking Holdings and Expedia Group can permit these advertisers, depending on marketplace dynamics, to adjust their CPC bids and obtain the same or increased levels of referrals, customers, bookings or revenue and profit at lower cost. This can occur if one or more advertisers with sufficient market share to influence our aggregate CPC levels change their return-on-investment targets for their spend on our marketplace. Our advertisers may curtail their spend on our platform in response to changes we may make to our product offering or strategy, which may also, in turn, negatively impact our revenue levels and profitability or increase the volatility on our marketplace.

We are subject to a number of factors that contribute to significant period-to-period volatility in our financial condition and results of operations.
Our financial condition and results of operations have varied and may continue to vary considerably from period to period. This was reflected in the quarter-to-quarter changes in our profitability and revenue in 2021 and 2020 as a result of the COVID-19 pandemic. We cannot reliably predict our advertisers' future advertising spend or CPC levels or other strategic goals they hope to achieve through changes in bidding on our marketplace and, as a result, it is difficult for us to forecast advertiser demand, especially since our advertisers can and often do change their CPC bidding levels with little or no notice to us. Our advertisers often pursue different marketing strategies and have varying levels of competitiveness based on their own competitive position. We believe that our advertisers continuously review their advertising spend on our platform and on other marketing channels, and continuously seek to optimize the allocation of their spend among us and our competitors. For example, the large OTAs have recently publicly emphasized their desire to continue to optimize the efficiency of their performance marketing spend.
We regularly compete with our advertisers in auctions for search engine keywords on Google and other search engines and adjust our spend on search engine marketing based on trends we see in our results. If changes in large advertisers' strategies on our marketplace were to cause us to spend significantly less on these marketing channels, we would also generate fewer Qualified Referrals, and as a result, our revenues and results of operations would be adversely affected. Such advertisers may also experience improvements in their competitiveness on these marketing channels, providing them with additional financial benefits from pursuing such a strategy.
Furthermore, any resulting changes in Referral Revenue, especially as a result of changes in CPC bidding levels by our largest advertisers, could result in our inability to reduce our Advertising Spend,
7




particularly on television, quickly enough to respond to the change in revenue. As we spend the great majority of our revenue on advertising, such a failure to reduce Advertising Spend quickly enough can have, and has in the past had, a sudden and significant adverse effect on our profitability and results of operations. Any resulting inability to meet financial guidance that we may communicate to the market in the future may have a material adverse effect on our business, results of operations, financial condition and prospects.

As a result of the change in the macroeconomic outlook, we have experienced and may in the future record impairments of intangible assets and goodwill.
As a result of the continued deterioration of macroeconomic conditions, including rising interest rates, increased inflation and more uncertainty in respect of the overall economic environment, we performed intangible assets and goodwill impairment analyses during the second and third quarters of 2022, as a result of which we recorded impairment charges totaling €184.6 million. We may record further impairment charges in the future due to further changes in the macroeconomic outlook.

Because we almost completely ceased television advertising in 2020, which resumed only at reduced levels in 2021 and 2022, we do not expect our past advertising campaigns to contribute the direct traffic to our platform that we had prior to the COVID-19 pandemic. This is expected to hinder our ability to grow our revenue, which could continue to harm our business and negatively affect our financial condition and results of operations.
We rely heavily on the trivago brand. Awareness, perceived quality and perceived differentiated attributes of our brand are important aspects of our efforts to attract and expand the number of users of our websites and apps. We significantly reduced our advertising budgets as a result of the COVID-19 pandemic. We believe our prior television advertising campaigns continued to have a significant positive effect on direct traffic volumes, even in periods after the advertising was aired. As we almost completely ceased advertising on television in 2020 and resumed such advertising at reduced levels in 2021 and 2022, we believe that in 2022 we did not benefit from prior campaigns as had been the case in the past, and we expect this to continue to be the case in the coming years. We anticipate that we will need to invest in television advertising campaigns in the next years to grow the volume of direct traffic to our platform.
In the future, our competitors may invest in innovative advertisement campaigns to improve their brand awareness, which could make it difficult for us to increase or maintain our own marginal returns on our advertisements. We may face this difficulty even if we make substantial investments in innovative technologies and concepts in our advertising. Increased advertising spend by our competitors, many of which have more resources than we do to promote their brands and services, could also result in significant increases in the pricing of one or more of our marketing and advertising channels, which could increase our costs for advertising (which already consume most of our revenue) or cause us to choose less costly but less effective marketing and advertising channels.
Television advertising has historically accounted for a large percentage of our Advertising Spend, and often has higher costs than other channels. We expect to continue to invest in television marketing campaigns, including in geographies where our brand is less well-known. As we make these investments, we may observe increasing prices in light of increased spending from competitors or may see reduced benefits from our advertising due to, among other things, increasing traffic share growth of search engines as destination sites for users and the declining viewership in certain age groups and changes in viewing patterns that reduce viewer exposure to advertising. In order to maintain or increase the effectiveness of our television advertisements, we have needed to develop new creative concepts in our advertisements, many of which are in a testing phase, and it may be that these advertisements may not be as effective in terms of Return on Advertising Spend as those we have used in the past. We have historically placed orders for television advertising in advance of the campaign season. In the event travel
8




demand is lower than we anticipated at the time we booked that advertising, we could suffer losses if we are unable to cut planned spending.
We believe the COVID-19 pandemic has accelerated the shift from linear TV to digital formats and expect this trend to continue. As a result of the downward trend of conventional television viewership in favor of streaming platforms and online video, we have begun investing in other channels that could potentially have a lower marginal Return on Advertising Spend. For example, in order to maintain our brand awareness, we have begun investing in other advertising formats, such as online video, with which we have less experience and which may prove less effective than TV advertising in the long run. If we are unable to maintain or enhance consumer awareness of our brand or to generate demand in a cost-effective manner, it may have a material adverse effect on our business, results of operations, financial condition and prospects.

Increasing competition in our industry could result in a loss of market share and higher traffic acquisition costs or reduce the value of our services to users and a loss of users, which would adversely affect our business, results of operations, financial condition and prospects.
We operate in an increasingly competitive travel industry. Many of our current and potential competitors, including hotels themselves (both hotel chains and independent hotels), and metasearch engines, such as Kayak, TripAdvisor, Skyscanner and Google Hotel Ads, locally focused metasearch engines, such as Check24, OTAs, such as Booking.com, Ctrip, TUI, trip.com and Brand Expedia, alternative accommodation websites, such as Airbnb and Vrbo (previously HomeAway), and other hotel websites, may have been in existence longer, may have larger user bases, may have wider ranges of products and services and may have greater brand recognition and customer loyalty in certain markets and/or significantly greater financial, marketing, personnel, technical and other resources than we do. Some of these competitors may be able to offer products and services on more favorable terms than we can. Google Hotel Ads and other metasearch websites, continue to expand globally, are increasingly competitive, have access to large numbers of users, and, in some cases, continue to adopt strategies and develop technologies and websites that are very similar to ours. In particular, Google has entered various aspects of the online travel market and has grown rapidly in this area, including by offering a flight meta-search product ("Google Flights"), a hotel meta-search product ("Google Hotel Ads"), a vacation rental meta-search product, a tours and activities product, an inspirational travel product, Google Travel (which is a planning tool that aggregates its flight, tours and activities and hotel and packages products in one website), and by integrating its hotel meta-search products and restaurant information and reservation products into its Google Maps app. Competition could result in higher traffic acquisition costs, lower CPC levels and reduced margins on our advertising services, loss of market share, reduced user traffic to our websites and reduced advertising by hotel companies and other accommodation advertisers on our websites.

We rely on search engines, particularly Google, to drive a substantial amount of traffic to our platform. If Google continues to promote its own products and services that compete directly with our accommodation search at the expense of traditional keyword auctions and organic search, our business, financial performance and prospects may be negatively impacted.
We rely on Bing, Google, Naver, Yahoo! and other Internet search engines to generate a substantial amount of traffic to our websites, principally through the purchase of hotel-related keywords. We obtain a significant amount of traffic via search engines and therefore utilize techniques such as search engine optimization and search engine marketing to improve our placement in relevant search queries. The number of users we attract from search engines to our platform is due in large part to how and where information from, and links to, our websites is displayed on search engine pages. Google and other search engines frequently update and change the logic that determines the placement and display of results of a user’s search. If a major search engine changes its algorithms in a manner that negatively affects the search engine ranking, paid or unpaid, of our websites or that of our third-party distribution
9




partners, or if competitive dynamics impact the costs or effectiveness of search engine optimization, search engine marketing or other traffic generating arrangements in a negative manner, it may have a material adverse effect on our business, results of operations, financial condition and prospects. In addition, if search engines, especially smaller players, decline in popularity, we may see adverse impacts if they provide us with fewer relevant leads or even shut down their services completely, resulting in even less competition in general search. In some instances, search and metasearch companies may change their displays or rankings in order to promote their own competing products or services or the products or services of one or more of our competitors. For example, Google, a significant source of traffic to our website, frequently promotes its own hotel search platform (which it refers to as “Google Hotel Ads”) at the expense of traditional keyword auctions and organic search results. This presents a challenge since we have significantly less flexibility to acquire traffic for our website using that platform compared to traditional hotel-related keyword advertising. In addition, our major advertisers might not be amenable in some cases to our using their inventory to compete with them on Google Hotel Ads, which may present a further difficulty if Google continues to direct traffic in this manner. Google’s promotion of its own competing products, or similar actions by Google in the future that have the effect of reducing our prominence or ranking on its search results, could have a substantial negative effect on our business, results of operations, financial condition and prospects.

Our business model and value proposition is focused primarily on providing users with search services for hotels. If user preferences shift from traditional hotel-based accommodation or if users expect our websites and apps to offer search for non-accommodation services, we may be unable to source and monetize that inventory to a sufficient degree.
Our success depends on continued innovation to provide features and services that make our websites and apps useful for users. While we have offered users the opportunity to search for alternative accommodation, such as vacation rentals, on our websites and apps, our primary historical focus has been on helping users search for accommodation at hotels. If user preferences shift away from traditional hotel-based accommodation, we may face challenges in integrating and monetizing new types of accommodation into our platform since those properties may have attributes substantially different from hotel rooms, our traditional area of focus. In addition, the online travel industry is rapidly evolving, and if we fail to predict the manner in which that market develops or if our competitors are able to acquire a larger share of the aggregate online accommodation searches at our expense, our financial performance may be harmed. In addition, we do not currently offer users the ability to search for air travel, rental cars, tours, cruises and other services with our advertisers, while they can book or otherwise obtain information about at least some of these services on the websites of nearly all of our major competitors. If we are unable to provide users with information they deem useful, or our competitors are able to provide more attractive offers for accommodation coupled with attractive offers for other services, or if our users demand to see more comprehensive offers akin to those of our competitors, this may have a substantial negative effect on our competitiveness, business, results of operations, financial condition and prospects.

If we do not innovate and provide tools and services that are sufficiently useful to users and advertisers, we may not remain competitive, and our revenue and results of operations could suffer.
Our competitors are constantly innovating in online accommodation-related services and features . As a result, we must continue to invest significant resources in research and development to continuously improve the speed, accuracy and comprehensiveness of our services. The emergence of alternative platforms and niche competitors who may be able to optimize services or strategies have required, and will continue to require, new and costly investments in technology. We have invested, and in the future may invest, in new business strategies and services to attain competitiveness. Some of the changes we are implementing may require us to make investments into what we perceive as longer-term profitable returns at the expense of short-term profitability, and as a result, we may continue to prioritize the quality of user experience over short-term monetization. In the future, we may need to provide alternative hotel
10




listing products, potentially including paid and non-paid placements, to ensure we have a competitive coverage of rates globally. These strategies and services may not succeed, and, even if successful, our revenue may not increase or we may not achieve the longer-term profitable returns that we expect. In addition, we may fail to adopt and adapt to new technology, especially as text-based Internet search, including through Google and Amazon, potentially moves to video and voice interfaces over the coming years, or we may not be successful in developing technologies that operate effectively across multiple devices and platforms. New developments in other areas could also make it easier for competitors to enter our markets due to lower up-front technology costs. If we are unable to continue offering innovative services or do not provide sufficiently comprehensive results for our users, we may be unable to attract additional users and advertisers or retain our current users and advertisers, which may have a material adverse effect on our business, results of operations, financial condition and prospects.

If we do not provide a broad set of offers to our users, we may not remain competitive, and our revenue and results of operations could suffer.
Our ability to attract users to our services depends in large part on providing a comprehensive set of accommodation search results and a broad range of offers across price ranges. To do so, we maintain relationships with OTAs, hotel chains, independent hotels and alternative accommodation providers to include their data in our search results. Although we maintain a very large searchable database of properties from around the world, we do not have relationships with some significant potential advertisers, including some major hotel chains, many independent hotels, smaller chains and certain large providers of alternative accommodations. The risk associated with incomplete coverage in our search results may increase if we see lower user interest in accommodation at hotels, for example as a result of any travel restrictions or because user preferences shift away from hotels to alternative accommodation. In addition, consolidation among advertisers, which may occur at increasing levels because of the general global economic situation, or a change to more coordinated or centralized marketing activities within OTA groups and hotel chains, could reduce the number of offers we have available in our marketplace for each hotel. The realization of any of these risks could make us less popular to our users and reduce the revenue we generate from referrals.

Several of our product features depend, in part, on our relationship with third parties to provide us with content and services.
We currently license, and incorporate into our websites, content and technology services from third parties. As we continue to improve the overall quality of our products, we may introduce new features that require us to incorporate new content or services, and this may require us to license additional rights. We cannot be sure that such technology will be available on commercially reasonable terms, if at all. In particular, certain third parties provide us with map products, content such as consumer reviews that we provide to our users along with our proprietary rating scores and hotel related data and information. If any of our third-party data providers terminate their relationships with us, the information that we provide to users may be limited or the quality of the information may suffer, which may negatively affect the implementation of our strategic initiatives, users’ perception of the value of our product and our reputation.

Many events beyond our control, including geopolitical events, may adversely affect the travel industry.
Many events beyond our control can adversely affect the travel industry, with a corresponding negative impact on our business and results of operations. Natural disasters, including hurricanes, tsunamis, earthquakes or volcanic eruptions, as well as other natural phenomena, such as outbreaks of the Zika virus, the Ebola virus, avian flu and, most recently, COVID-19, as well as other pandemics and epidemics, have disrupted normal travel patterns and levels in the past. The COVID-19 pandemic has had a significant negative impact on our global business volumes, particularly in 2020 and 2021. The travel
11




industry is also sensitive to events that may discourage travel, such as work stoppages or labor unrest, political instability, regional hostilities, such as the ongoing military conflict between Russia and Ukraine, increases in fuel prices, imposition of taxes or surcharges by regulatory authorities, travel-related accidents and terrorist attacks or threats. We do not have insurance coverage against loss or business interruption resulting from war and terrorism, and we may be unable to fully recover any losses we sustain due to other factors beyond our control under our existing insurance coverage. The occurrence of any of the foregoing events may have a material adverse effect on our business, results of operations, financial condition and prospects.

Our global operations expose us to risks associated with currency fluctuations, which may adversely affect our business.
Our platform is available in a large number of jurisdictions outside the Eurozone. As a result, we face exposure to movements in currency exchange rates around the world. Changes in foreign exchange rates can amplify or mute changes in the underlying trends in our Advertising Spend, revenue and Revenue per Qualified Referral. A large portion of our advertising expenses are incurred in the local currency of the particular geographic market in which we advertise, with a significant amount incurred in U.S. dollar. Although we largely denominate our CPCs in euro and have relatively little direct foreign currency translation with respect to our revenue, we believe that our advertisers’ decisions on the share of their booking revenue they are willing to pay to us are based on the currency in which the hotels being booked are priced. Accordingly, we have observed that advertisers tend to adjust their CPC bidding based on the relative strengthening or weakening of the euro as compared to the local functional currency in which the booking with our advertisers is denominated. Currency exchange-related exposures also include but are not limited to re-measurement gains and losses from changes in the value of foreign denominated monetary assets and liabilities; translation gains and losses on foreign subsidiary financial results that are translated into euro upon consolidation; fluctuations in hotel revenue and planning risk related to changes in exchange rates between the time we prepare our annual and quarterly forecasts and when actual results occur.
We do not currently hedge our foreign exchange exposure. Depending on the size of the exposures and the relative movements of exchange rates, if we choose not to hedge or fail to hedge effectively our exposure, we could experience a material adverse effect on our financial statements and financial condition. As we have seen in some recent periods, in the event of severe volatility in foreign exchange rates, these exposures can increase, and the impact on our results of operations can be more pronounced. In addition, the current environment and the global nature of our business have made hedging these exposures more complex.

We are subject to counterparty default risks.
We are subject to the risk that a counterparty to one or more of our customer arrangements will default on its performance obligations. A counterparty may fail to comply with its commercial commitments, which could then lead it to default on its obligations with little or no notice to us. This could limit our ability to take action to mitigate our exposure. Additionally, our ability to mitigate our exposures may be constrained by the terms of our commercial arrangements or because market conditions prevent us from taking effective action. In addition, our ability to recover any funds from financially distressed or insolvent counterparties is limited, and our recovery rates in such instances have historically been very low. Because a majority of our accounts receivable are owed by Booking Holdings and Expedia Group, delays or a failure to pay by any of these advertisers could result in a significant increase in our credit losses, and we may be unable to fund our operations. Counterparties may also be located in countries where enforcement of our creditors’ rights is more difficult than in the countries where our major OTA advertisers are located. If one of our counterparties becomes insolvent or files for bankruptcy, our ability to recover any losses suffered as a result of that counterparty’s default may be limited by the liquidity of the counterparty or the applicable laws governing the bankruptcy proceedings, and in any event, the customers of that
12




counterparty may seek redress from us, even though the booking with that counterparty was not conducted on our platform. In addition, almost all of our agreements with OTAs, hotel chains and independent hotels may be terminated at will or upon prior notice of thirty days or less by either party. In the event of such default or termination, we could incur significant losses or reduced revenue, which could adversely impact our business, results of operations, financial condition and prospects.

Legal and regulatory risks
We are involved in various legal proceedings and may experience unfavorable outcomes, which could adversely affect our reputation, business and financial condition.
We are involved in various legal proceedings and disputes involving alleged infringement of third-party intellectual property rights, competition and consumer protection laws, including, but not limited to, the legal proceedings described in the following risk factor and in Item 8A under "Legal Proceedings". These matters may involve claims for substantial amounts of money or for other relief that might necessitate changes to our business or operations. The defense of these actions has been, and will likely continue to be, both time consuming and expensive and the outcomes of these actions cannot be predicted with certainty. Determining provisions for pending litigation is a complex, fact-intensive process that requires significant legal judgment. It is possible that unfavorable outcomes in one or more such proceedings could result in substantial payments that would adversely affect our business, consolidated financial position, results of operations, reputation or cash flows in a particular period.

Regulators' continued focus on the consumer-facing business practices of online travel companies may adversely affect our business, financial performance, results of operations or business growth.
A number of regulatory authorities in Europe, Australia and elsewhere have initiated litigation and/or market studies, inquiries or investigations relating to online marketplaces and how information is presented to consumers using those marketplaces, including practices such as search results rankings and algorithms, discount claims, disclosure of charges, and availability and similar messaging. For example, on January 20, 2020, the Australian Federal Court issued a judgment in the Australian Competition and Consumer Commission's (ACCC) case against us regarding our advertising and website display practices in Australia. On April 22, 2022, the Australian Federal Court issued a judgment ordering us to pay a penalty of AUD 44.7 million. We paid the penalty balance of €29.6 million (AUD 44.7 million) in the second quarter of 2022 and costs arising from the proceedings. Parts of the court’s opinions included views that differed significantly from those of other national regulators and raised concerns about the function of our marketplace and the adequacy of disclosures to consumers regarding how advertisers that pay higher CPCs generally receive better advertising placement on our website. Since then, two purported class actions have been filed in Israel and Ontario, Canada, making allegations about our advertising and/or display practices broadly similar to aspects of the case brought by the ACCC. Plaintiffs’ motion for class certification in the Ontario action was denied on November 28, 2022. Plaintiffs have since filed a notice of appeal asking that the motion for class certification be granted. The class action filed in Israel is at an early stage.
Should other national courts or regulators take a similar view of our business model to that of the Australian Federal Court and the ACCC, or should changes in our business practices or those prevalent in our sector following the attention brought on by this litigation or other regulatory matters reduce the attractiveness, competitiveness or functionality of our platform and the services we offer, or should our reputation or that of our sector continue to suffer, or should we have to pay substantial amounts due to any such regulatory action or proceeding, our business, results of operations, financial condition and prospects could be adversely affected.
In addition, many governmental authorities in the markets in which we operate are also considering additional and potentially diverging legislative and regulatory proposals that would increase the level and
13




complexity of regulation on Internet display, disclosure and advertising activities. There also are, and will likely continue to be, an increasing number of laws and regulations pertaining to the Internet and online commerce that may relate to liability for information retrieved from, transmitted over or displayed on the Internet, display of certain taxes, charges and fees, online editorial, user-generated or other third-party content, user or other third-party privacy, data security, behavioral targeting and online advertising, taxation, liability for third-party activities and the quality of services.

We process, store and use user and employee personal data, which entails reputational, litigation and liability risks associated to any actual or perceived potential failure to comply with relevant legal obligations, which are constantly evolving.
Personal data information is increasingly subject to legislation and regulations in numerous jurisdictions around the world. We are in particular subject to the EU (European Union) General Data Protection Regulation 2016/679 or “GDPR”, in effect since May 25, 2018, which has recently led to the imposition of significant fines on various companies by EU data protection authorities. The invalidation of the EU-U.S. Privacy Shield and increase in focus and enforcement action from EU data protection authorities in relation to cross-border transfers of personal data, could have a significant adverse effect on our ability to engage with certain third party service providers should that require a transfer of personal data outside of the EEA (European Economic Area - EU countries and also Iceland, Liechtenstein and Norway).
Furthermore, several EU data protection authorities have issued new or additional guidance concerning the ePrivacy Directive's requirements regarding the use of cookies and similar technologies, and have in some cases brought (and may seek to bring in the future) enforcement action in relation to those requirements.
Following the UK’s exit from the European Union, the UK Government has transposed the GDPR into UK national law, creating the “UK GDPR”, which is complemented by the Data Protection Act 2018. However, the possible adoption of a data protection bill currently under discussion in the UK Parliament might introduce significant changes to the UK data privacy regulation.
The Brazilian General Data Protection Law (LGPD), Federal Law no. 13,709/2018, is in force since September 18, 2020 and its penalties are enforceable since August 2021. The California Consumer Privacy Act of 2018 (CCPA) became effective in January 2020 and is substantially amended by the California Consumer Privacy Rights Acts, which became operative in January 2023 and imposes new privacy requirements and rights for consumers in California. In the United States, other state data privacy laws have or will also take effect, for example in Virginia as of January 1, 2023, in Colorado and Connecticut as of July 1, 2023 and Utah as of December 31, 2023.
A number of data protection laws (including the GDPR and the UK GDPR) have introduced mandatory breach reporting to regulators and, under certain circumstances, to the individuals whose personal data was compromised in the breach.
Many other jurisdictions are considering or are about to adopt data protection regulations, which are sometimes inconsistent or conflicting. While we strive to monitor and comply with this complex and ever-changing patchwork of laws, a failure or perceived or alleged failure to comply with data privacy requirements in one of the jurisdictions where we operate or target users may significantly harm our businesses. In addition, we could be adversely affected if data privacy regulations are expanded (through new regulation or through legal rulings) to require major changes in our business practices and we may incur substantial compliance-related costs and expenses that are likely to increase over time. Implementation of and compliance with these laws and regulations may be more costly or take longer than we anticipate, or could otherwise adversely affect our business operations, which could negatively impact our financial position or cash flows.

14




Changes in, and continued implementation and enforcement of, international trade and anti-corruption laws and regulations could affect our ability to remain in compliance with such laws and regulations and could have a materially adverse effect on our business, results of operations, financial condition and prospects.
The United States (acting through, among other government agencies, the SEC, the U.S. Department of Justice and the U.S. Department of the Treasury, Office of Foreign Assets Control (OFAC), as well as other foreign authorities, such as the United Kingdom, continue to be focused on the implementation and enforcement of economic and trade and anti-corruption laws and regulations, across industries. For example, U.S. sanctions generally prohibit transactions conducted within U.S. jurisdiction in, with, involving or relating to certain countries and territories subject to comprehensive sanctions, including, currently, the Crimea region of the Ukraine, Cuba, Iran, North Korea and Syria, and certain specifically designated individuals and entities (including those individuals and entities listed on OFAC's Specially Designated Nationals and Blocked Persons List), as well as parties owned by such designated individuals and entities. In addition, as a result of Russia’s invasion of Ukraine, governmental authorities in the United States, the European Union, and the United Kingdom, among others, launched an expansion of coordinated sanctions and export control measures, including sanctions against certain individuals and entities and prohibiting or limiting certain financial and commercial transactions. We believe that our activities comply with applicable trade and anti-corruption laws and regulations, including the laws and regulations administered and enforced by OFAC, the U.S. Foreign Corrupt Practices Act and the U.K. Bribery Act. As applicable laws and regulations are enacted or amended, and the interpretations of those laws and regulations evolve, we cannot guarantee that our programs and policies will be deemed compliant by all applicable regulatory authorities or at all times In the event that our controls should fail or are found to be not in compliance for any reasons, including as a result of changes to our products and services or the behavior of our advertisers, we could be subject to monetary damages, civil and criminal penalties, litigation and damage to our reputation and the value of our brand.

We may not be able to adequately protect our intellectual property, which could harm the value of our brand and adversely affect our business.
We regard our intellectual property, including our business processes and other proprietary information, as critical to our success, and we rely on trademark and trade secret laws, domain name registration, confidentiality and non-disclosure procedures and contractual provisions and license agreements, where applicable, to protect our proprietary rights. If we are not successful in protecting our intellectual property, it could have a material adverse effect on our business, results of operations, financial condition and prospects.
Effective trademark and service mark protection may not be available in every country in which our services are provided. The laws of certain countries do not protect proprietary rights, such as trade secrets, to the same extent as the laws of the United States and, therefore, in certain jurisdictions, we may be unable to protect our proprietary technology adequately against unauthorized third-party copying or use, which could adversely affect our competitive position. In addition, certain characteristics of the Internet, in particular the anonymity, may make the protection and enforcement of our intellectual property difficult and in some cases, even impossible. We have licensed in the past, and expect to license in the future, certain of our proprietary rights, such as trademarks, to third parties. These licensees may take actions that might diminish the value of our proprietary rights or harm our reputation, even if we have agreements prohibiting such activity. Moreover, we utilize intellectual property and technology developed or licensed by third parties, and we may not be able to obtain or continue to obtain licenses and technologies from these third parties at all or on reasonable terms. Also, to the extent that third parties are obligated to indemnify us for breaches of our intellectual property rights, these third parties may be unable to meet these obligations. Any of these events may have a material adverse effect on our business, results of operations, financial condition and prospects.
We have registered domain names for websites that we use in our business, such as www.trivago.com, www.trivago.de, www.trivago.co.uk and weekend.com. Our competitors could attempt to capitalize on our
15




brand recognition by using domain names similar to ours. Domain names similar to ours have been registered in the United States and elsewhere, and in some countries the domain name “trivago,” or spelling variations of it, may be owned by other parties. We may be unable to prevent third parties from acquiring and using domain names that infringe on, are similar to, or otherwise decrease the value of, our brand or our trademarks or service marks. Protecting and enforcing our rights to our domain names and determining the rights of others may require litigation, which, whether or not successful, could result in substantial costs and diversion of management attention, as well as a loss in customer trust in the brand.

We are, and may in the future be, subject to legal claims alleging that we infringe, misappropriate or otherwise violate the intellectual property rights of third parties.
Our commercial success depends on our ability to conduct our business without infringing, misappropriating or otherwise violating any intellectual property owned by third parties. We may be subject to liability if our products, services, software or other technology, or the operations of our business infringe, misappropriate or otherwise violate the patents, copyrights, trademarks or other intellectual property rights of third parties. Intellectual property challenges have been increasingly brought against members of the travel industry, and third parties may bring legal claims, or threaten to bring legal claims, that their intellectual property rights are being infringed, misappropriated or otherwise violated by us, including by means of counterclaims against us as a result of the assertion of our intellectual property rights.
We do currently, and could in the future, face claims that we have infringed the intellectual property rights of others. Legal proceedings involving intellectual property rights are highly uncertain and can involve complex legal and scientific questions, and any claims against us or such providers could require us to spend significant time and money in litigation or pay damages. Such claims could also delay or prohibit the use of existing, or the release of new, products, services or processes, and the development of new technology or intellectual property. We cannot assure you that we will achieve a favorable outcome of any such claims, and any such actual or threatened claims (whether or not valid) could adversely impact our reputation and result in direct and indirect costs, all of which may have an adverse impact on our operations and financial performance. Even if we believe such third party claims are without merit, a court may hold that we have infringed, misappropriated or otherwise violated such intellectual property rights or we may settle claims to avoid the cost and uncertainty of litigation. If we were to be found liable for any such infringement, misappropriation or other violation, we could be required to rebrand, redesign, reengineer or modify our products and services (including our platform), pay substantial monetary damages, including possible treble damages and attorneys’ fees, or royalties and enter into costly license agreements (if available at all) to obtain the rights to use necessary technology, and we could be subject to injunctions preventing us from using some or all of our products, services or technology. Any payments we are required to make and any injunctions with which we are required to comply as a result of infringement claims could be costly.
Even if intellectual property claims brought by or against us are settled or resolved in our favor, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential or proprietary information could be compromised by disclosure during this type of litigation. In addition, there could be public announcements of the results of hearings, motions or other interim proceedings or developments, and if securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on the price of our securities.
Any of the foregoing could divert management’s attention and materially and adversely affect our business, financial condition, results of operations and cash flows.

16




Operational risks
The competition for highly skilled personnel, including senior management and technology professionals is intense. If we are unable to retain or motivate key personnel or hire, retain, and motivate qualified personnel, especially as the broader job market undergoes structural changes that increase our costs, our business would be harmed.
We believe our success has depended, and continues to depend, on the efforts and talents of our senior management and our highly skilled team members, including our software engineers and other technology professionals who are key to designing code and algorithms necessary to our business. Our workforce has declined from 1,247 on December 31, 2019 to 709 as of December 31, 2022. This reduction in workforce has resulted in the loss of institutional knowledge, relationships or expertise for critical roles. This reduction may also have a negative impact on employee morale and productivity, and could make it more difficult to retain valuable key employees, divert attention from operating our business, create personnel capacity constraints and hamper our ability to grow, develop innovative products and compete, any of which could impede our ability to operate or meet strategic objectives.
We continue to face intense competition for new talent as the broader job market appears to undergo structural changes that have further exacerbated the competitive environment. We compete with companies that have far greater financial resources than we do as well as companies that promise short-term growth opportunities and/or other benefits. These companies may be able to provide attractive offers to employees in critical roles who have gained valuable and marketable experience in our flat organizational structure. The competition for talent in our industry has in the past and may in the future increase our personnel expenses, which may adversely affect our results of operations. In addition, we may be unable to hire or retain certain high-performing employees when the price of our ADSs is low, as a significant portion of the compensation they receive consists of equity grants. If we do not succeed in attracting well-qualified employees, or retaining or motivating existing employees, including senior management, our business would be adversely affected. The loss of the services of any key individual could negatively affect our business.

We are dependent upon the quality of traffic in our network to provide value to our advertisers, and any failure in our ability to deliver quality traffic and/or the metrics to demonstrate the value of the traffic could have a material and adverse impact on the value of our websites to our advertisers and adversely affect our revenue.
We use technology and processes to monitor the quality of the internet traffic that we deliver to our advertisers and have identified metrics to demonstrate the quality of that traffic and identify low quality clicks such as non-human processes, including robots, spiders, the mechanical automation of clicking and other types of invalid clicks or click fraud. Even with such monitoring in place, there is a risk that a certain amount of low-quality traffic will be delivered to such online advertisers. Such low-quality or invalid traffic may be detrimental to our relationships with advertisers and could adversely affect our advertising pricing and revenue.

We rely on assumptions, estimates and data to make decisions about our business, and any inaccuracies in, or misinterpretation of, such information could negatively impact our business.
We take a data-driven, testing-based approach to managing our business, where we use our proprietary tools and processes to measure and optimize end-to-end performance of our platform. Our ability to analyze and rapidly respond to the internal data we track enables us to improve our platform and make decisions about allocating marketing spend and ultimately convert any improvements into increased revenue. While the internal data we use to judge the effectiveness of changes to our platform and to make improvements to how we make decisions about allocating Advertising Spend are based on what we believe to be reasonable assumptions and estimates, our internal tools are not independently verified by a third party and have a number of limitations. We only have access to limited information about user
17




behavior compared to many of our competitors that in many cases can record detailed information about users who log onto their websites or who complete a booking or other transaction with them.
In addition, our ability to track user behavior is also subject to considerable limitations, for example, relating to our ability to use cookies and browser extensions to analyze behavior over time, and to difficulties pertaining to users who use multiple devices to conduct their search for accommodation. In particular, users can block or delete cookies through their browsers or “ad-blocking” software or apps. The most common Internet browsers allow users to modify their browser settings to prevent cookies from being accepted by their browsers or are set to block third-party cookies by default. At least one major browser has introduced extensive privacy features, including the imposition of a strict time limit on tracking tools' lifespans. Further, the mobile app ecosystem is constantly evolving, in particular with how the operating systems handle third party data tracking and usage. Changes in these technologies or developments further limiting data availability may inhibit our ability to use user and web analytics data to better understand and track our users’ preferences. We use this information to improve our platform, to optimize our marketing campaigns and our advertisers’ campaigns and to detect and prevent fraudulent activities, which all may be adversely affected. We believe that many of our competitors, in particular Google, have substantial advantages compared to us in their ability to understand and track users' behavior. In addition, we are to a significant extent dependent upon certain advertisers for specific types of user information, including, for example, as to whether a user ultimately completed a booking. Our or our advertisers’ methodologies for tracking this information may change over time. Some countries have already adopted digital services tax, or other taxes of a similar nature, while other countries may also adopt such taxes in the future. In addition to increasing our operational expenses, digital services tax or other taxes of a similar nature make it more difficult for us to measure the marginal efficiency of our Advertising Spend among marketing channels as such taxes affect not only how we allocate our spend but also how these marketing channels and our advertisers make decisions about their businesses. Additionally, our use of such tracking tools may be subject to regulation by certain data protection laws,
If the internal tools we use to judge the effectiveness of changes to our platform produce or are based on information that is incomplete or inaccurate, or we do not have access to important information, or if we are not sufficiently rigorous in our analysis of that information, or if such information is the result of algorithm or other technical or methodological errors, the decisions we make relating to our website, marketplace and allocation of marketing spend may not result in the positive effects in terms of profitability, revenue and user experience that we expect, which may negatively impact our business, results of operations, financial condition and prospects.

In the past, we identified a material weakness in our internal control over financial reporting. If the measures we have implemented, including internal controls, fail to be effective in the future, any such failure could result in material misstatements of our financial statements, cause investors to lose confidence in our reported financial and other public information, harm our business and adversely impact the trading price of our ADSs.
Our management is responsible for establishing and maintaining internal controls over financial reporting, disclosure controls, and compliance with other requirements of the Sarbanes-Oxley Act and the rules promulgated by the SEC thereunder. 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 in accordance with U.S. GAAP. In addition, our independent registered public accounting firm is required to attest to the effectiveness of our internal control over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act. Satisfying these requirements requires us to dedicate a significant amount of time and resources, including for the development, implementation, evaluation and testing of our internal controls over financial reporting. Although no material weaknesses were identified in connection with the attestation of the effectiveness of our internal control over financial reporting as of December 31, 2022, 2021 or 2020, our management cannot guarantee that our internal controls and disclosure controls will prevent all possible errors or fraud. In addition, the internal controls that we have implemented could fail to be effective in the future. This failure could result in material misstatements in
18




our financial statements, result in the loss of investor confidence in the reliability of our financial statements and subject us to regulatory scrutiny and sanctions. This could, in turn, harm our business and the market value of our ADSs. In addition, we may be required to incur costs in improving our internal controls system and the hiring of additional personnel.

We may experience difficulties in implementing new business and financial systems.
We continue to transition certain business and financial systems to systems that reflect the size, scope and complexity of our operations. These systems include an internally developed tool to manage our invoicing and various third-party developed tools to assist us with internal system integration and financial management. The process of migrating our legacy systems could disrupt our ability to timely and accurately process and report key aspects of our financial statements as we will rely on these systems for information that is included in or otherwise relevant for our financial statements. In addition, while the implementation of these systems is intended to increase accuracy of financial reporting and reduce our reliance on manual procedures and actions, the transition may affect the accuracy of reporting as we align some of our processes. With respect to these systems, certain additional financial controls and processes will be required and may result in changes to the current control environment. These changes will need to be assessed for effective implementation and effectiveness in mitigating inherent risk in these processes. This evaluation could result in deficiencies in our internal control over financial reporting, including material weaknesses, in future periods. Any difficulties in implementing the new software or related failures of our internal control over financial reporting could adversely affect our business, results of operations, financial condition and prospects, and could cause harm to our reputation.

Increased computer circumvention capabilities could result in security breaches in our information systems, which may significantly harm our business.
We cannot guarantee that our security measures or the security measures of external service providers will prevent all security breaches, intrusions or attacks, as computer circumvention tools and techniques become more advanced. A party that is able to circumvent our security systems or the systems of an external service provider could improperly obtain confidential information or cause significant disruptions to our operations. In the past, we have experienced cyber-related fraud and “denial-of-service” type of attacks on our system, which have made portions of our website unavailable for periods of time. Any actions that impact the availability of our website or apps could cause a loss of substantial business volume during the occurrence of any such incident and such risks are likely to increase as the tools to carry out such actions become more advanced and sophisticated. In addition to the considerable resources needed to address or mitigate their effects, security breaches could result in reputational harm and negative publicity with users and advertisers whether existing or potential, losing confidence in the security of our systems.
Security breaches could also expose us to risk of loss and possible liability and subject us to regulatory or criminal penalties and sanctions as well as civil litigation, including under various data protection laws.

Any significant disruption in service on our websites and apps or in our computer systems, most of which are currently hosted by third-party providers, could damage our reputation and result in a loss of users, which would harm our business and results of operations.
Our brand, reputation and ability to attract and retain users to use our websites and apps depend upon the reliable performance of our network infrastructure and content delivery processes. We have experienced interruptions in these systems in the past, including server failures that temporarily slowed down the performance of our websites and apps, in particular as we opted to use more cloud-based services. We may experience service interruptions in the future. Interruptions in these systems, whether due to system failures, computer viruses or physical or electronic break-ins, could affect the security or availability of our services on our websites and apps and prevent or inhibit the ability of users to access
19




our service, which, in turn, can have a material adverse effect on our financial condition, business and results of operation. Problems with the reliability or security of our systems could harm our reputation. Damage to our reputation and the cost of remedying these problems could negatively affect our business, financial condition and results of operations.
While we still lease or own servers for internal communication and services, our systems mostly rely on cloud-hosted services. We are therefore reliant upon external providers, including Amazon Web Services and Google Cloud Platform, to provide us with cloud computing infrastructure. Any disruption to our use of services furnished by these providers or an unanticipated increase in costs from using those services could negatively impact our business operations. Our systems and operations are vulnerable to damage or interruption from fire, flood, power loss, telecommunications failure, terrorist attacks, acts of war, electronic and physical break-ins, computer viruses, earthquakes and similar events. The occurrence of any of the foregoing events could result in damage to our systems or could cause them to fail completely, and our insurance may not cover such events or may be insufficient to compensate us for losses that may occur.
Our systems are not completely redundant worldwide, so a failure of our system at one site could result in reduced functionality for our users, and a total failure of our systems could cause our websites or apps to be inaccessible to our users. Problems faced by our third-party service providers with the telecommunications network providers with which they contract or with the systems by which they allocate capacity among their users, including us, could adversely affect the experience of our users. Our third-party service providers could decide to close their facilities without adequate notice. Any financial difficulties, such as bankruptcy or reorganization, faced by our third-party service providers or any of the service providers with whom they contract may have negative effects on our business, the nature and extent of which are difficult to predict. If our third-party service providers are unable to keep up with our growing needs for capacity, this could have an adverse effect on our business, results of operations, financial condition and prospects. Any errors, defects, disruptions or other performance problems with our services could harm our reputation and may have a material adverse effect on our business, results of operations, financial condition and prospects.

We rely on information technology to operate our business and maintain our competitiveness, and any failure to invest in and adapt to technological developments and industry trends could harm our business.
We depend on the use of sophisticated information technologies and systems, including technology and systems used for websites and apps, customer service, supplier connectivity, communications, fraud detection and administration. As our operations grow in size, scope and complexity, we need to continuously improve and upgrade our systems and infrastructure to offer an increasing number of user-enhanced services, features and functionalities, while maintaining or improving the reliability and integrity of our systems and infrastructure. In addition, we may not be able to maintain our existing systems or replace or introduce new technologies and systems as quickly as we would like or need in a cost-effective manner. If these changes result in our infrastructure being unreliable or if they do not result in the benefits we anticipate, our business, results of operations, financial condition and prospects could be adversely affected.

Our brand is subject to reputational risks and impairment.
We have developed our trivago brand through extensive marketing campaigns, website promotions, customer referrals and the use of a dedicated sales force. We cannot guarantee that our brand will not be damaged by circumstances that are outside our control or by third parties, such as hackers, or interfaces with their clients, such as subcontractors’ employees or sales forces, with a resulting negative impact on our activities. For example, we may be subject to negative press accounts or other negative publicity regarding our product, brand or business practices, which may, among other things, cause us reputational harm. Such negative publicity may become more prevalent as a result of announced or future regulatory
20




investigations or litigation relating to practices in our marketplace and related online travel-related market segments. We believe this occurred when the Australian Federal Court issued a judgment finding that we had engaged in conduct in breach of the Australian Consumer Law. Social media’s reach may magnify any negative publicity and messages can “go viral” necessitating effective crisis response in real time. A failure on our part to protect our image, reputation and the brand under which we market our products and services may have a material adverse effect on our business, results of operations, financial condition and prospects.

We are subject to risks associated with a corporate culture that promotes entrepreneurialism among our employees and continuous learning.
We have delegated considerable operational autonomy and responsibility to our employees, including allowing our employees flexible working hours that allow them to determine when, where and for how long they work. We also often make changes to our internal organizational structure to support operational autonomy and individual advancement. As a consequence, people in key positions may have less experience in the relevant operational areas. As our employees have significant autonomy and may lack experience when performing new operational roles, this could result in poor decision-making. We have also implemented remote working for our employees since the COVID-19 pandemic but have since limited the number of days that employees may work remotely. Our competitors may offer more operational autonomy and flexibility in regard to remote work, which may, in turn, make it difficult for us to retain and motivate our employees. The realization of any of these risks could have a material adverse effect on our business, results of operations, financial condition and prospects.

Integration of acquired assets and businesses could result in operating difficulties and other harmful consequences.
We have made small strategic acquisitions in the past. We expect to continue to evaluate a wide array of potential strategic transactions. We could enter into transactions that could be material to our financial condition and results of operations. The process of integrating an acquired company, business or technology may create unforeseen operating difficulties and expenditures. The areas where we face risks in respect of acquisitions include:
diversion of management time and focus from operating our business to acquisition diligence, negotiation and closing processes, as well as post-closing integration challenges;
implementation or remediation of controls, procedures and policies at the acquired company;
coordination of product, engineering and sales and marketing functions;
retention of key employees from the businesses we acquire;
responsibility for liabilities or obligations associated with activities of the acquired company before the acquisition;
litigation or other claims in connection with the acquired company; and
in the case of foreign acquisitions, the need to integrate operations across different geographies, cultures and languages and to address the particular economic, currency, political and regulatory risks associated with specific countries.
Furthermore, companies that we have acquired, and that we may acquire in the future, may employ security and networking standards at levels we find unsatisfactory. The process of enhancing infrastructure to improve security and network standards may be time-consuming and expensive and may require resources and expertise that are difficult to obtain. Acquisitions could also increase the number of potential vulnerabilities and could cause delays in detection of a security breach, or the timeliness of

recovery from a breach. Failure to adequately protect against attacks or intrusions could expose us to security breaches of, among other things, personal user data and credit card information that may have a material adverse effect on our business, results of operations, financial condition and prospects.
Our failure to address these risks or other problems encountered in connection with our past or future acquisitions and investments could delay or eliminate any anticipated benefits of such acquisitions or investments, incur unanticipated liabilities and may have a material adverse effect on our business, results of operations, financial condition and prospects.

Risks related to our ongoing relationship with our shareholders
Expedia Group controls our company and has the ability to control the direction of our business.
As of December 31, 2022, Expedia Group owned Class B shares representing 61.2% of our issued share capital and 84.3% of the voting power in us. As long as Expedia Group owns a majority of the voting power in us, Expedia Group will be able to control many corporate actions that require a shareholder vote.
This voting control limits the ability of other shareholders to influence corporate matters and, as a result, we may take actions that shareholders other than Expedia Group do not view as beneficial. This voting control may also discourage transactions involving a change of control of our company, including transactions in which you as a holder of ADSs (representing our Class A shares) might otherwise receive a premium for your shares. Furthermore, Expedia Group generally has the right at any time to sell or otherwise dispose of any Class A shares and Class B shares that it owns, including the ability to transfer a controlling interest in us to a third party, without the approval of the holders of our Class A shares and without providing for the purchase of Class A shares.

Expedia Group’s interests may conflict with our interests, the interests of the Founders and the interests of our shareholders, and conflicts of interest among Expedia Group, the Founders and us could be resolved in a manner unfavorable to us and our shareholders.
Various conflicts of interest among us, the Founders and Expedia Group could arise. Ownership interests of directors or officers of Expedia Group in our shares, and ownership interests of members of our management board and supervisory board in the stock of Expedia Group, or a person’s service as either a director or officer of both companies, could create or appear to create potential conflicts of interest, including when those directors and officers are faced with decisions relating to our company. In recent years, Expedia Group, and brands affiliated with it, consistently accounted for a substantial portion of our revenue
Potential conflicts of interest could also arise if we decide to enter into any new commercial arrangements with Expedia Group’s businesses in the future or in connection with Expedia Group’s desire to enter into new commercial arrangements with third parties. Expedia Group has the right to separately pursue acquisitions of businesses that we may also be interested in acquiring, or companies that may directly compete with us. Expedia Group may choose to pursue these corporate opportunities directly rather than through trivago.
Furthermore, disputes may arise between Expedia Group and us relating to our past and ongoing relationships, and these potential conflicts of interest may make it more difficult for us to favorably resolve such disputes, including those related to:
tax, employee benefit, indemnification and other matters;
the nature, quality and pricing of services Expedia Group agrees to provide to us;
sales, other disposals, purchases or other acquisitions by Expedia Group of shares in us (including when our share price is lower than in comparable prior periods); and
22




business combinations involving us.
We may not be able to resolve any potential conflicts, and even if we do, the resolution may be less favorable to us than if we were dealing with an unaffiliated party. While we are controlled by Expedia Group, we may not have the leverage to negotiate amendments to these agreements, if required, on terms as favorable to us as those we would negotiate directly with an unaffiliated third party.

Risks related to ownership of our Class A shares and ADSs
You may not be able to exercise your right to vote the Class A shares underlying your ADSs.
Holders of ADSs may exercise voting rights with respect to the Class A shares represented by their ADSs only in accordance with the provisions of the deposit agreement. The deposit agreement provides that, upon receipt of notice of any meeting of holders of our Class A shares, including any general meeting of our shareholders, the depositary will, as soon as practicable thereafter, fix a record date for the determination of ADS holders who shall be entitled to give instructions for the exercise of voting rights. Upon timely receipt of notice from us, the depositary shall distribute to the holders as of the record date (i) the notice of the meeting or solicitation of consent or proxy sent by us, (ii) a statement that such holder will be entitled to give the depositary instructions and a statement that such holder may be deemed, if the depositary has appointed a proxy bank as set forth in the deposit agreement, to have instructed the depositary to give a proxy to the proxy bank to vote the Class A shares underlying the ADSs in accordance with the recommendations of the proxy bank and (iii) a statement as to the manner in which instructions may be given by the holders.
You may instruct the depositary of your ADSs to vote the Class A shares underlying your ADSs. Otherwise, you will not be able to exercise your right to vote unless you withdraw our Class A shares underlying the ADSs you hold. However, you may not know about the meeting far enough in advance to withdraw those Class A shares. The depositary, upon timely notice from us, will notify you of the upcoming vote and arrange to deliver voting materials to you. We cannot guarantee that you will receive the voting materials in time to ensure that you can instruct the depositary to vote the Class A shares underlying your ADSs. In addition, the depositary and its agents are not responsible for failing to carry out voting instructions or for the manner of carrying out voting instructions. This means that you may not be able to exercise your right to vote, and there may be nothing you can do if the Class A shares underlying your ADSs are not voted as you had requested.
Under the deposit agreement for the ADSs, we may choose to appoint a proxy bank. In this event, the depositary will be deemed to have been instructed to give a proxy to the proxy bank to vote the Class A shares underlying your ADSs at shareholders’ meetings if you do not vote in a timely fashion and in the manner specified by the depositary.
The effect of this proxy is that you cannot prevent the Class A shares representing your ADSs from being voted, and it may make it more difficult for shareholders to exercise influence over our company, which could adversely affect your interests. Direct holders of our Class A shares are not subject to this proxy.
You may not receive distributions on the Class A shares represented by our ADSs or any value for them if it is illegal or impractical to make them available to holders of ADSs.
The depositary of our ADSs has agreed to pay to you the cash dividends or other distributions it or the custodian receives on our Class A shares after deducting its fees and expenses. You will receive these distributions in proportion to the number of our Class A shares your ADSs represent. However, the depositary is not responsible if it decides that it is unlawful or impractical to make a distribution available to any holders of ADSs. We have no obligation to take any other action to permit the distribution to any holders of our ADSs or Class A shares. This means that you may not receive the distributions we make on our Class A shares or any value from them if it is illegal or impractical for us to make them available to you. These restrictions may have a material adverse effect on the value of your ADSs.
23




You may be subject to limitations on the transfer of your ADSs.
Your ADSs, which may be evidenced by American Depositary Receipts, are transferable on the books of the depositary. However, the depositary may close its books at any time or from time to time when it deems expedient in connection with the performance of its duties. The depositary may refuse to deliver, transfer or register transfers of your ADSs generally when our books or the books of the depositary are closed, or at any time if we or the depositary think it is advisable to do so because of any requirement of law, government or governmental body, or under any provision of the deposit agreement, or for any other reason.

We do not expect to pay any dividends for the foreseeable future.
The continued operation of, and strategic initiatives for, our business will require substantial cash. Accordingly, we do not anticipate that we will pay any dividends on our ADSs for the foreseeable future. Any determination to pay dividends in the future will be at the discretion of our management board and will depend upon our results of operations, financial condition, contractual restrictions relating to indebtedness we may incur, restrictions imposed by applicable law and other factors our management board deems relevant.

Risks related to our corporate structure
The rights of shareholders in companies subject to Dutch corporate law differ in material respects from the rights of shareholders of corporations incorporated in the United States.
We are a Dutch public company with limited liability (naamloze vennootschap). Our corporate affairs are governed by our articles of association and by the laws governing companies incorporated in the Netherlands. The rights of shareholders and the responsibilities of members of our management board and supervisory board may be different from the rights and obligations of shareholders in companies governed by the laws of U.S. jurisdictions. In the performance of their duties, our management board and supervisory board are required by Dutch law to consider the interests of our company, its shareholders, its employees and other stakeholders. It is possible that some of these parties will have interests that are different from, or in addition to, your interests as a holder of ADSs representing our Class A shares.
We are not obligated to and do not comply with all the best practice provisions of the Dutch Corporate Governance Code (or the DCGC). This may affect your rights as a shareholder.
We are a Dutch public company with limited liability (naamloze vennootschap) and are subject to the DCGC. The DCGC contains both principles and best practice provisions for management boards, supervisory boards, shareholders and general meetings of shareholders, financial reporting, auditors, disclosure, compliance and enforcement standards. The DCGC applies to all Dutch companies listed on a government-recognized stock exchange, whether in the Netherlands or elsewhere, including Nasdaq.
The DCGC is based on a “comply or explain” principle. Accordingly, companies are required to disclose in their annual reports filed in the Netherlands whether they comply with the provisions of the DCGC. If they do not comply with those provisions (e.g., because of a conflicting U.S. requirement), the company is required to give the reasons for such non-compliance. We do not comply with all the best practice provisions of the DCGC. This may affect your rights as a shareholder and you may not have the same level of protection as a shareholder in a Dutch company that fully complies with the DCGC.

Our dual-class share structure with different voting rights limit your ability as a holder of Class A shares to influence corporate matters and could discourage others from pursuing any change of control transactions that holders of our Class A shares may view as beneficial.
We have a dual-class share structure such that our share capital consists of Class A shares and Class B shares. In respect of matters requiring the votes of shareholders, based on our dual-class share structure, holders of Class A shares are entitled to one vote per share, while holders of Class B shares are entitled to ten votes per share. Each Class B share is convertible into one Class A share at any time by the holder thereof, while Class A shares are not convertible into Class B shares under any circumstances. Each of our ADSs represents one Class A share.
As of December 31, 2022, Expedia Group owned Class B shares representing 61.2% of our share capital and 84.3% of the voting power in us, and the Founders owned Class B shares representing 8.3% of our share capital and 11.5% of the voting power in us due to the disparate voting powers associated with our dual-class share structure. The Founders also hold Class A shares representing approximately 7.3% of our share capital. See “ Item 7: Major shareholders and related party transactions”. As a result of the dual-class share structure and the concentration of ownership, Expedia Group has considerable influence over matters such as decisions regarding mergers, consolidations and the sale of all or substantially all of our assets, appointment and dismissal of management board members and supervisory board members and other significant corporate actions. This concentration of ownership may discourage, delay or prevent a change in control of our company, which could have the effect of depriving the holders of ADSs (representing Class A shares) of the opportunity to receive a premium for their shares as part of a sale of our company and may reduce the price of our Class A shares. This concentrated control limits your ability to influence corporate matters that holders of Class A shares may view as beneficial.

German and European insolvency laws are substantially different from U.S. insolvency laws and may offer our shareholders less protection than they would have under U.S. insolvency laws.
As a company with its registered office in Germany, we are subject to German insolvency laws in the event any insolvency proceedings are initiated against us including, among other things, directive (EU) 2019/1023 of the European Parliament and of the Council of June 20, 2019 on insolvency proceedings). Should courts in another EU jurisdiction determine that the insolvency laws of that EU jurisdiction apply to us in accordance with and subject to such EU regulations, the courts in that country could have jurisdiction over the insolvency proceedings initiated against us. Insolvency laws in Germany or the relevant other European country, if any, may offer our shareholders less protection than they would have under U.S. insolvency laws and make it more difficult for them to recover the amount they could expect to recover in a liquidation under U.S. insolvency laws.

Dutch law and our articles of association may contain provisions that may discourage a takeover attempt.
Dutch law and provisions of our articles of association may in the future impose various procedural and other requirements that would make it more difficult for shareholders to effect certain corporate actions and would make it more difficult for a third party to acquire control of us or to effect a change in the composition of our management board and supervisory board. For example, such provisions include our dual-class share structure that gives greater voting power to the Class B shares owned by Expedia Group and our Founders, the binding nomination structure for the appointment of our management board members and supervisory board members, and the provision in our articles of association which provides that certain shareholder decisions can only be passed if proposed by our management board. Moreover, our management board, with the approval of our supervisory board, can invoke a cooling-off period of up to 250 days when shareholders, using their right to have items added to the agenda for a general meeting or their right to request a general meeting, propose an agenda item for our general meeting to dismiss, suspend or appoint one or more managing directors or supervisory directors (or to amend any provision in our articles of association dealing with those matters) or when a public offer for our company is made or
25




announced without our support, provided, in each case, that our management board believes that such proposal or offer materially conflicts with the interests of trivago and its business. During a cooling-off period, our general meeting cannot dismiss, suspend or appoint managing directors and supervisory directors (or amend the provisions in our articles of association dealing with those matters) except at the proposal of our management board.

U.S. investors may have difficulty enforcing civil liabilities against us or members of our management board and supervisory board.
We are organized and existing under the laws of the Netherlands, and, as such, under Dutch private international law rules the rights of our shareholders and the civil liability of our directors and executive officers are governed in certain respects by the laws of the Netherlands. Most members of our management board and supervisory board are non-residents of the United States. The ability of our shareholders in certain countries other than the Netherlands to bring an action against us, our directors and executive officers may be limited under applicable law. In addition, substantially all of our assets are located outside the United States.
As a result, it may not be possible for shareholders to effect service of process within the United States upon us or our directors and executive officers or to enforce judgments against us or them in U.S. courts, including judgments predicated upon the civil liability provisions of the federal securities laws of the United States. In addition, it is not clear whether a Dutch court would impose civil liability on us or any of our directors and executive officers in an original action based solely upon the federal securities laws of the United States brought in a court of competent jurisdiction in the Netherlands.
As of the date of this annual report, there is no treaty in effect between the United States and the Netherlands providing for the reciprocal recognition and enforcement of judgments, other than arbitration awards, in civil and commercial matters. It is noted that, on today's date, the Hague Convention on Choice of Court Agreements of June 30, 2005 has entered into force for the Netherlands, but has not entered into force for the United States. The Hague Convention of July 2, 2019 on the Recognition and Enforcement of Foreign Judgements in Civil or Commercial Matters has not entered into force for either the Netherlands or the United States. Accordingly, a judgment rendered by a court in the United States, whether or not predicated solely upon U.S. securities laws, would not automatically be recognized and enforced by the competent Dutch courts. However, if a person has obtained a judgment rendered by a court in the United States that is enforceable under the laws of the United States and files a claim with the competent Dutch court, the Dutch court will in principle give binding effect to such judgment if (i) the jurisdiction of the U.S. court was based on a ground of jurisdiction that is generally acceptable according to international standards, (ii) the judgment by the U.S. court was rendered in legal proceedings that comply with the Dutch standards of proper administration of justice including sufficient safeguards (behoorlijke rechtspleging), (iii) binding effect of such U.S. judgment is not contrary to Dutch public order (openbare orde) and (iv) the judgment by the foreign court is not incompatible with a decision rendered between the same parties by a Dutch court, or with a previous decision rendered between the same parties by a foreign court in a dispute that concerns the same subject and is based on the same cause, provided that the previous decision qualifies for recognition in the Netherlands. Even if such a U.S. judgement is given binding effect, a claim based thereon may, however, still be rejected if the U.S. judgment is not or no longer formally enforceable. Dutch courts may deny the recognition and enforcement of punitive damages or other awards. Moreover, a Dutch court may reduce the amount of damages granted by a U.S. court and recognize damages only to the extent that they are necessary to compensate actual losses or damages. Enforcement and recognition of judgments of U.S. courts in the Netherlands are solely governed by the provisions of the Dutch Code of Civil Procedure (Wetboek van Burgerlijke Rechtsvordering).
Based on the lack of a treaty as described above, U.S. investors may not be able to enforce against us or our directors, representatives or certain experts named herein who are residents of the Netherlands or countries other than the United States any judgments obtained in U.S. courts in civil and commercial matters, including judgments under the U.S. federal securities laws.

We rely on the foreign private issuer and controlled company exemptions from certain corporate governance requirements under Nasdaq rules.
As a foreign private issuer whose ADSs are listed on Nasdaq, we are permitted to follow certain home country corporate governance practices pursuant to exemptions under Nasdaq rules. A foreign private issuer must disclose in its annual reports filed with the SEC each requirement under Nasdaq rules with which it does not comply, followed by a description of its applicable home country practice. Our Dutch home country practices may afford less protection to holders of our ADSs. We follow in certain cases our home country practices and rely on certain exemptions provided by Nasdaq rules to foreign private issuers, including, among others, an exemption from the requirement to hold an annual meeting of shareholders no later than one year after an issuer’s fiscal year end, exemptions from the requirement that a board of directors be comprised of a majority of independent directors, exemptions from the requirements that an issuer’s compensation committee should be comprised solely of independent directors, and exemptions from the requirement that share incentive plans be approved by shareholders. See “Item 16G.     Corporate governance” for more information on the significant differences between our corporate governance practices and those followed by U.S. companies under Nasdaq rules. As a result of our reliance on the corporate governance exemptions available to foreign private issuers, you will not have the same protection afforded to shareholders of companies that are subject to all of Nasdaq’s corporate governance requirements.
In addition to the exemptions we rely on as a foreign private issuer, we also rely on the “controlled company” exemption under Nasdaq corporate governance rules. A “controlled company” under Nasdaq corporate governance rules is a company of which more than 50% of the voting power is held by an individual, group or another company. Our principal shareholder, Expedia Group, controls a majority of the combined voting power of our outstanding shares, making us a “controlled company” within the meaning of Nasdaq corporate governance rules. As a controlled company, we have elected not to comply with certain corporate governance standards, including the requirement that a majority of our supervisory board members are independent and the requirement that our compensation committee consist entirely of independent directors.

Risks related to taxation
We may become taxable in a jurisdiction other than Germany, and this may increase the aggregate tax burden on us.
Since our incorporation, we have had, on a continuous basis, our place of effective management in Germany. Therefore, we believe that we are a tax resident of Germany under German national tax laws. As an entity incorporated under Dutch law, however, we also qualify as a tax resident of the Netherlands under Dutch national tax laws. However, given that substantially all of our operations (along with all employees, management board members and fixed assets) are in Germany, based on current tax laws of the United States, Germany and the Netherlands, as well as applicable income tax treaties, and current interpretations thereof, we believe that we are tax resident solely in Germany for the purposes of the 2012 convention between the Federal Republic of Germany and the Netherlands for the avoidance of double taxation with respect to taxes on income.
The applicable tax laws, tax treaties or interpretations thereof may change. Furthermore, whether we have our place of effective management in Germany and are as such wholly tax resident in Germany is largely a question of fact and degree based on all the circumstances, rather than a question of law, which facts and degree may also change. Changes to applicable tax laws, tax treaties or interpretations thereof and changes to applicable facts and circumstances (e.g., a change of board members or the place where board meetings take place), or changes to applicable income tax treaties, including a change to MLI tie-breaker reservation, may result in our also becoming a tax resident of the Netherlands or another jurisdiction (other than Germany), potentially also triggering an exit tax liability in Germany or the Netherlands. As a consequence, our overall effective income tax rate and income tax expense could
27




materially increase, which could have a material adverse effect on our business, results of operations, financial condition and prospects, which could cause our ADS price and trading volume to decline.

Application of existing tax laws, rules or regulations are subject to interpretation by taxing authorities.
The application of various national and international income and non-income tax laws, rules and regulations to our historical and new services is subject to interpretation by the applicable taxing authorities. These taxing authorities have become more aggressive in their interpretation and enforcement of such laws, rules and regulations over time, as governments are increasingly focused on ways to increase revenue. This has contributed to an increase in the audit activity and harsher stances taken by tax authorities. As such, additional taxes or other assessments may be in excess of our current tax reserves or may require us to modify our business practices to reduce our exposure to additional taxes going forward, any of which may have a material adverse effect on our business, results of operations, financial condition and prospects.
Significant degrees of judgment and estimation are required in determining our worldwide tax liabilities. In the ordinary course of our business, there are transactions and calculations, including intercompany transactions and cross-jurisdictional transfer pricing for which the ultimate tax determination is uncertain or otherwise subject to interpretation. Tax authorities may disagree with our intercompany charges, including the amount of or basis for such charges, cross-jurisdictional transfer pricing or other matters and assess additional taxes. Although we believe our tax estimates are reasonable, the final determination of tax audits could be materially different from our historical income tax provisions and accruals in which case we may be subject to additional tax liabilities, possibly including interest and penalties, which could have a material adverse effect on our business, results of operations, financial condition and prospects.

Amendments to existing tax laws, rules or regulations or enactment of new unfavorable tax laws, rules or regulations could have an adverse effect on our business and financial performance.
Many of the underlying laws, rules or regulations imposing taxes and other obligations were established before the growth of the digital economy. If the tax or other laws, rules or regulations were amended, or if new unfavorable laws, rules or regulations were enacted, the results could increase our tax payments or other obligations, prospectively or retrospectively, subject us to interest and penalties, decrease the demand for our services if we pass on such costs to the user, result in increased costs to update or expand our technical or administrative infrastructure or effectively limit the scope of our business activities if we decided not to conduct business in particular jurisdictions. As a result, these changes may have a material adverse effect on our business, results of operations, financial condition and prospects.
In addition, in the past, Germany and foreign governments have introduced proposals for tax legislation, or have adopted tax laws, that could have a significant adverse effect on our tax rate, or increase our tax liabilities, the carrying value of deferred tax assets, or our deferred tax liabilities. For example, pursuant to the release of “base erosion and profit shifting” (BEPS) final Action Plans, and its implementation through the MLI, several countries including the countries in which we operate, have begun implementing the adopted MLI positions. Further, the OECD's work on a two pillar solution to address the tax challenges arising from the digitalization of the economy is expected to result in new legislation in various countries. Several countries have unilaterally adopted digital services taxes or other similar taxes, while some other countries may adopt such taxes in the future. Such ongoing developments and other new initiatives could result, depending on how they are ultimately implemented, in incremental taxes, and thus may adversely impact our business, results of operations, financial condition and prospects.
We are constantly exploring changes to our business structures to support our operations while managing operational and financial risk for ourselves and our shareholders and to make our services more financially attractive to our customers. Though these changes would be undertaken to manage
28




operational and financial risk, we may experience unanticipated material tax liabilities which could have a material adverse effect on our business, results of operations, financial condition and prospects.
Our effective tax rate in the future could also be adversely affected by changes to our operating structure, changes in the mix of earnings in countries with differing statutory tax rates, or changes in the deferred tax assets and liabilities position.

We may be classified as a passive foreign investment company, or PFIC, which could result in adverse U.S. federal income tax consequences to U.S. Holders of the ADSs.
Based on the market price of our ADSs and the composition of our income, assets and operations, we do not believe that we should be treated as a PFIC for U.S. federal income tax purposes for the taxable year ended December 31, 2022. However, the application of the PFIC rules to us is subject to certain ambiguity. In addition, this is a factual determination that must be made annually after the close of each taxable year based on the composition of our income and assets as well as the trading price of our ADSs. Because the value of our assets, including goodwill, for purposes of the asset test may be determined by reference to the market price of our ADSs, fluctuations in the market price of the ADSs may cause us to become a PFIC. Therefore, there can be no assurance that we will not be classified as a PFIC for any future taxable year. We would be classified as a PFIC if, after the application of certain look-through rules, either: (1) 75% or more of our gross income for such year is “passive income” (as defined in the relevant provisions of the Internal Revenue Code of 1986, as amended), or (2) 50% or more of the value of our assets (determined on the basis of a quarterly average) during such year is attributable to assets that produce or are held for the production of passive income. Certain adverse U.S. federal income tax consequences could apply to a U.S. Holder (as defined in “Item 10: Additional information - E. Taxation - Material U.S. federal income tax considerations ”) if we are treated as a PFIC for any taxable year during which such U.S. Holder holds ADSs.

Certain of our ADS holders may be unable to claim tax credits to reduce German withholding tax applicable to the payment of dividends.
We do not anticipate paying dividends on our ADSs for the foreseeable future. As a Dutch-incorporated but German tax resident company, however, if we pay dividends, such dividends will be subject to German (and potentially Dutch) withholding tax. Currently, the applicable German withholding tax rate is 26.375% of the gross dividend. This German tax can be reduced to the applicable double tax treaty rate, however, by an application filed by the tax payer for a specific German tax certificate with the German Federal Central Tax Office (Bundeszentralamt für Steuern). If a tax certificate cannot be delivered to the ADS holder due to applicable settlement mechanics or lack of information regarding the ADS holder, holders of the shares or ADSs of a German tax resident company may be unable to benefit from any available double tax treaty relief while they may be unable to file for a credit of such withholding tax in its jurisdiction of residence. Further, the payment made to the ADS holder equal to the net dividend may, under the tax law applicable to the ADS holder, qualify as taxable income that is in turn subject to tax, which could mean that a dividend is effectively taxed twice. Our ADSs have been issued by a depositary with a direct link to the U.S. Depository Trust Company, or DTC, which should reduce the risk that the applicable German withholding tax certificate cannot be delivered to the ADS holder. However, there can be no guarantee that the information delivery requirement can be satisfied in all cases, which could result in adverse tax consequences for affected ADS holders.
Investors should note that the interpretation circular (Besteuerung von American Depositary Receipts (ADR) auf inländische Aktien) issued by the German Federal Ministry of Finance (Bundesministerium der Finanzen) dated May 24, 2013 (reference number IV C 1-S2204/12/10003), or ADR Tax Circular, is not binding for German courts and it is not clear whether or not a German tax court will follow the ADR Tax Circular in determining the German tax treatment of our specific ADSs. Further concerns regarding the applicability of the ADR Tax Circular may arise due to the fact that the ADR Tax Circular refers only to German stock and not to shares in a Dutch N.V. If the ADSs are determined not to fall within the scope of
29




application of the ADR Tax Circular, and thus profit distributions made with respect to the ADSs are not treated as a dividend for German tax purposes, the ADS holder would not be entitled to a refund of any taxes withheld on the dividends under German tax law. See “Item 10: Additional information - E. Taxation - German taxation of ADS holders”).

If we ever pay dividends, we may need to withhold tax on such dividends payable to holders of our ADSs in both Germany and the Netherlands.
We do not intend to pay any dividends to holders of ADSs. However, if we do pay dividends, we may need to withhold tax on such dividends both in Germany and the Netherlands. As an entity incorporated under Dutch law, any dividends distributed by us are subject to Dutch dividend withholding tax on the basis of Dutch domestic law. However, on the basis of the double tax treaty between Germany and the Netherlands, the Netherlands will be restricted in imposing these taxes if we continue to be a tax resident of Germany and our place of effective management is in Germany. However, Dutch dividend withholding tax is still required to be withheld from dividends if and when paid to Dutch resident holders of our ADSs (and non-Dutch resident holders of our ADSs that have a permanent establishment in the Netherlands to which their shareholding is attributable). As a result, upon a payment (or deemed payment) of dividends, we will be required to identify our shareholders and/or ADS holders in order to assess whether there are Dutch residents (or non-Dutch residents with a permanent establishment in the Netherlands to which the shares are attributable) in respect of which Dutch dividend tax has to be withheld. Such identification may not always be possible in practice. If the identity of our shareholders and/or ADS holders cannot be determined, withholding of both German and Dutch dividend tax from such dividend may occur upon a payment of dividends.
Furthermore, the withholding tax restriction referred to above is based on the current reservation of Germany under the MLI with respect to the dual resident entities. If Germany changes its MLI reservation on Article 4 of the MLI, we may not be entitled to any benefits of the double tax treaty between Germany and the Netherlands, including the withholding tax restriction, as long as Germany and the Netherlands do not reach an agreement on our tax residency for purposes of the double tax treaty between Germany and the Netherlands, except to the extent and in such manner as may be agreed upon by the authorities. As a result, any dividends distributed by us during the period till when no such agreement has been reached between Germany and the Netherlands, may be subject to withholding tax both in Germany and the Netherlands.
In addition, a proposed law is currently pending before the Dutch parliament, namely the Emergency act conditional exit dividend tax (Spoedwet conditionele eindafrekening dividendbelasting) which would, if enacted, impose, possibly with retroactive effect, a dividend withholding (exit) tax on certain deemed distributions if we cease to be a Dutch tax resident and become a tax resident of a jurisdiction that is not a member of the EU or the EEA, when such jurisdiction does not satisfy certain conditions. In some cases, we would have a right to recover the amount of tax from our shareholders when such shareholder is not entitled to an exemption.

General risk factors
Our share price may be volatile or may decline regardless of our operating performance.
The market price for our ADSs has been, and will likely continue to, be volatile, and there continues to be relatively few ADSs outstanding, resulting in relatively low liquidity in our ADSs. Our results of operations are also subject to material quarterly fluctuations that may affect the volatility of our ADSs. In addition, the market price of our ADSs may fluctuate significantly in response to a number of factors, most of which we cannot control, including:
actual or anticipated fluctuations in our results of operations;
variance in our financial performance from the expectations of market analysts or from the financial guidance that we have communicated;
announcements by us or our competitors of significant business developments, acquisitions or expansion plans;
changes in the prices of our competitors or those paid to us by our customers;
our involvement in litigation or regulatory investigations;
our sale of ADSs or other securities in the future;
a sale of ADSs by our major shareholders in the future;
market conditions in our industry;
changes in key personnel;
the trading volume of our ADSs;
changes in the estimation of the future size and growth rate of our markets; and
general economic and market conditions.
The stock markets, including Nasdaq, have in the past experienced extreme price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many Internet and technology companies.

Future sales and/or issues of our ADSs, or the perception in the public markets that such sales may occur, may depress our ADS price.
Sales of a substantial number of our ADSs in the public market, or the perception that these sales could occur, could adversely affect the price of our ADSs and could impair our ability to raise capital through the sale of additional ADSs. Our Founders continue to hold a significant shareholding in us and have made sales of ADSs in recent years. Our Founders may conduct further significant sales of ADSs in the future. See "Item 7: Major shareholders and related party transactions - A. Major Shareholders" for more information. The ADSs are freely tradable without restriction under the Securities Act, except for any of our ADSs that may be held or acquired by our management board members, supervisory board members, executive officers and other affiliates, as that term is defined in the Securities Act or ADSs sold in transactions not subject to the registration requirements of the Securities Act, which will in each case be restricted securities under the Securities Act. Restricted securities may not be sold in the public market unless the sale is registered under the Securities Act or an exemption from registration is available.

Our Class B shares are convertible into Class A shares, which may be sold subject to certain restrictions in the Amended and Restated Shareholders’ Agreement.
In the future, we may also issue our securities in connection with investments or acquisitions. The amount of ADSs issued in connection with an investment or acquisition could constitute a material portion of our
31




then-outstanding ADSs. Any issuance of additional securities in connection with investments or acquisitions may result in additional dilution to you.

If securities or industry analysts publish inaccurate or unfavorable research about our business, our ADS price could decline.
The trading market for our ADSs depends in part on the research and reports that securities or industry analysts publish about us or our business. If securities or industry analyst coverage results in downgrades of our ADSs or publishes inaccurate or unfavorable research about our business, our ADS price would likely decline.

Item 4: Information on the company
A.History and development of the company
trivago was conceived by graduate school friends Rolf Schrömgens, Peter Vinnemeier and Stephan Stubner, who initially operated trivago out of a garage in Düsseldorf, Germany. trivago GmbH was incorporated in 2005, and its business eventually developed into a leading global hotel and accommodation search platform. Mr. Stubner left the company in 2006 and another graduate school friend, Malte Siewert, joined the founding team.
Between 2006 and 2008, several investors invested €1.4 million in trivago. In 2010, Insight Venture Partners acquired 27.3% of the equity ownership of trivago for €42.5 million. Expedia Group acquired 63.0% of the equity ownership in trivago in 2013, purchasing all outstanding equity from non-Founders and some outstanding equity from the Founders and subscribing for a certain number of newly issued shares for a total of €477 million. Expedia Group subsequently increased its shareholdings slightly in the second and fourth quarter of 2016 through the purchase of shares held by certain employees who had previously exercised stock options.
We were incorporated on November 7, 2016 as travel B.V., a private company with limited liability (besloten vennootschap met beperkte aansprakelijkheid) under Dutch law. On December 16, 2016, we completed our initial public offering, or IPO, on the Nasdaq Stock Exchange. In connection with our IPO, we converted into a public company with limited liability (naamloze vennootschap) under Dutch law pursuant to a deed of amendment and conversion and changed our legal name to trivago N.V. On September 7, 2017, we consummated the cross-border merger of trivago GmbH into and with trivago N.V.
We are registered with the Trade Register of the Chamber of Commerce in the Netherlands (Kamer van Koophandel) under number 67222927. Our corporate seat is in Amsterdam, the Netherlands, and our registered office is at Kesselstraße 5 - 7, 40221 Düsseldorf, Germany (under number HRB 79986). Our telephone number is +49-211-3876840000.

Segment reporting
Management has identified three reportable segments, which correspond to our three operating segments: the Americas, Developed Europe and Rest of World. Our Americas segment is comprised of Argentina, Brazil, Canada, Chile, Colombia, Ecuador, Mexico, Peru, the United States and Uruguay. Our Developed Europe segment is comprised of Austria, Belgium, Denmark, Finland, France, Germany, Ireland, Italy, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. Our Rest of World segment is comprised of all other countries, the most significant by revenue of which are Japan, Australia, Turkey, Israel and India. Other revenue is included in Corporate and Eliminations, along with all corporate functions and expenses, excluding direct advertising.
We determined our operating segments based on how our chief operating decision makers manage our business and evaluate operating performance. Our primary operating metric is Return on Advertising Spend, or ROAS, for each of our segments, which compares Referral Revenue to Advertising Spend.
For additional information relating to the development of our company, see “Item 4: Information on the company - B. Business overview.

B. Business overview
Overview
trivago is a global accommodation search platform and our mission is "to be your companion to experience our world". We are focused on reshaping the way travelers search for and compare different types of accommodations, such as hotels, vacation rentals and private apartments, while enabling our advertisers to grow their businesses by providing them with access to a broad audience of travelers via our websites and apps. Our platform allows travelers to make informed decisions by personalizing their search for accommodation and providing them with access to a deep supply of relevant information and prices. In the year ended December 31, 2022, we had 311.6 million Qualified Referrals and, as of that date, offered access to more than 5.0 million hotels and other types of accommodation, including 3.8 million units of alternative accommodation such as vacation rentals and private apartments, in over 190 countries. See “Item 5: Operating and financial review and prospects” for a further description of Qualified Referrals.
We believe that the number of travelers accessing our websites and apps makes us an important and scalable marketing channel for our advertisers, which include OTAs, hotel chains, independent hotels and providers of alternative accommodation. Additionally, our ability to refine user intent through our search function allows us to provide advertisers with transaction-ready referrals. Recognizing that advertisers on our marketplace have varying objectives and varying levels of marketing resources and experience, we provide a range of services to enable advertisers to improve their performance on our marketplace.
Our hotel and accommodation search platform can be accessed globally via 53 localized websites and apps available in 31 languages. Users can search our platform on desktop and mobile devices, and benefit from a familiar user interface, resulting in a consistent user experience.
In the year ended December 31, 2022, we generated revenue of €535.0 million, net loss of €127.2 million, and Adjusted EBITDA of €107.5 million. Adjusted EBITDA is a non-GAAP financial measure, and we therefore direct you to Item 5: Operating and financial review and prospects - G.    Non-GAAP financial measures" for an additional description of Adjusted EBITDA and a reconciliation of Adjusted EBITDA to net income/(loss). See, also "Item 5: Operating and financial review and prospects - Results of Operations - Revenue" for Referral Revenue by segment, representing a breakdown according to principal geographic markets.

trivago's search platform
Our accommodation search platform forms the core of our user experience. It is a search and comparison product, and users do not book directly on our platform. When they click on an offer for a hotel room or other accommodation at a certain price, they are referred to our advertisers’ websites where they can complete their booking. We maintain one of the largest searchable databases of accommodations in the world. As of December 31, 2022, our database included more than 5.0 million (2021: 5.0 million) hotels and other types of accommodations, gathered through OTAs, hotel chains, independent hotels and providers of alternative accommodations. As of December 31, 2022, we offered access on our search platform to more than 3.8 million (2021: 3.8 million) units of alternative accommodation, such as vacation rentals and private apartments.
Our users initially search via a text-based search function, which supports searches across a broad range of criteria. The search results show a user an accommodation listing page. For hotels, the page contains aggregated information, including:
Accommodation information: We display information that we believe is relevant to the user, such as the name, pictures, amenities, star rating and distance to selected location;
trivago ratings index: We aggregate millions of ratings globally. We produce a score for each property, which is updated daily to render relevant and valuable insights for our users while saving them time when searching for the ideal hotel or other accommodation. The rating is a single, easy-to-use score out of ten;
Reviews: We provide reviews from third parties in a clear and concise format; and
Price comparison: We prominently display a suggested advertised deal for each hotel or other accommodation, while also listing additional available offers from our advertisers in a list format, including room types, amenities and payment options. To learn more about how we determine the prominence given to offers and their placement in our search results, see "Marketplace" below.
We provide our services through websites and apps, including through our mobile-optimized website available on mobile device browsers. Our full-featured native mobile app is available on iPhone, iPad, Android Phone, Android Tablet and HarmonyOS.

Marketing
Through test-driven marketing operations, we have positioned our brand as a key part of the process for travelers in finding their ideal hotel or other accommodation. We focus the efforts of our marketing teams and Advertising Spend towards building effective and efficient messaging for a broad audience. We believe that building and maintaining our brand and clearly articulating our role in travelers' hotel or other accommodation discovery journey, will continue to drive both travelers and advertisers to our platform to connect in a mutually beneficial way.
Our application of data-led improvement and innovation also informs our marketing strategy, which we believe enables us to become increasingly more effective with our marketing spend. We have built tools that capture data and calculate our return on many elements of our brand and performance marketing measures.
Brand marketing
To grow brand awareness and increase the likelihood that users will visit our websites and use our apps, we invest in brand marketing globally across a broad range of media channels, including TV marketing, on demand video platforms and online video advertising.
The amount and nature of our Advertising Spend varies across our geographic markets, depending on multiple factors including the emphasis we wish to place on profitability versus traffic growth, cost
34




efficiency, marginal effectiveness of our Advertising Spend, local media dynamics, the size of the market and our existing brand presence in that market.
We also generate travel content as a means of engaging with travelers, which is distributed online via social media, our online magazine and email.
Performance marketing
We market our services and directly acquire traffic for our websites by purchasing travel and hotel-related keywords from general search engines and through advertisements on other online marketing channels. These activities include advertisements through search engines, such as Bing, Google, Naver and Yahoo! and through display advertising campaigns on advertising networks, affiliate websites and social media sites. Mobile app marketing remains important given the high usage of that device type.
Allocation of marketing spend
We take a data-driven, testing-based approach to making decisions about allocating marketing spend, where we use tools, processes and algorithms, many of which are proprietary, to measure and optimize performance end-to-end, starting with the pretesting of the creative concept and ending with the optimization of media spend. We continue to develop the methodologies we use to inform decisions about how much we spend on each marketing channel. We look at a range of metrics including behavior on the trivago website as well as subsequent booking behavior with our advertisers to determine the optimal mix of spend. We assess the returns on marketing spend by looking at a range of factors, both short and long-term, including impact on referral revenue, user retention and advertiser engagement.

Sales & Account management
Our sales and account management team builds and grows relationships with OTAs, hotel chains and other travel companies, including hospitality technology providers. From facilitating their participation in our marketplace to growing the adoption of our products, our dedicated teams provide ongoing consultation and guidance to our advertisers around CPC and CPA (or cost-per-acquisition) bidding options, product updates, and optimization opportunities. We proactively engage with our advertisers to better understand their specific objectives in order to offer solutions through our marketplace.
Independent hotels receive dedicated attention through our customer success team. With tailored solutions for hoteliers, we enable independent hotels to generate direct business through their official website by advertising their rates directly in our price comparison, allowing them to compete with the large OTAs and chains. Our team accompanies hoteliers throughout the sales cycle, from creating awareness about our products to onboarding them.
Marketing tools and services for advertisers
We offer our advertisers a suite of marketing tools to help promote their listings on our platform and drive traffic to their websites. Our tools and services provide tailored solutions for OTAs, hotel chains and independent hotel advertisers to help them manage their presence on our marketplace and steer their investments according to their budget and traffic needs.

Marketplace
We design our algorithm to display hotel room and other accommodation rate offers that we believe will be attractive to our users, emphasizing those offers that we believe are more likely to be clicked and ultimately booked on our advertisers' websites. We prominently display a suggested deal for each hotel, which is determined based on our algorithm as described below, while also listing additional offers made available to us from our advertisers in a list format.
We consider the completion of hotel and other accommodation bookings, which we refer to as booking conversion, to be a key indicator of user satisfaction on our website. At the core of our ability to match our
35




users’ searches with large numbers of hotel and other accommodation offers is our auction platform, which we call our marketplace. With our marketplace, we provide advertisers a competitive forum to access user traffic by facilitating a vast quantity of auctions on any particular day.
CPC Bidding Model
Our advertisers continue to participate in our marketplace primarily through CPC, or cost-per-click, bidding. Advertisers that use this method submit CPC bids for each user click on an advertised rate for a hotel. By clicking on a given rate, an individual user is referred to that advertiser’s website where the user can complete the booking. Advertisers can submit and adjust CPC bids on our marketplace frequently - as often as daily - on a property-by-property and market-by-market basis, and provide us with information on hotel room and other accommodation rates and availability on a near-real time basis.
We also offer our advertisers the opportunity to advertise and promote their business through hotel/accommodation sponsored placements on our websites. This service is generally also priced on a CPC basis and guarantees that advertiser placement in a pre-selected slot at the top of our search results.
Cost-per-acquisition model
Beginning in 2020, we began to offer our advertisers the opportunity to participate in our marketplace on a CPA, or cost-per-acquisition, basis, whereby an advertiser pays us a percentage of the booking revenue that ultimately result from a referral. The CPA model enables our advertisers to be charged only in the event a user ultimately completes a booking, enabling them to reduce their risk as they only pay when an actual booking takes place. Advertisers may set multiple CPA campaigns in a given market, and update CPA inputs for each campaign frequently. When an advertiser opts to participate in our marketplace on a CPA basis, we calculate a CPC bid-equivalent based on potential booking value, and the CPA inputs. This equivalent is then used for the purpose of the ranking and sorting algorithm described below.
Ranking and sorting algorithm
In determining the prominence given to offers and their placement in our search results, including in comparison search results for a given location and on detail pages for a given property, our proprietary algorithm considers a number of factors in a dynamic, self-learning process. These include (but are not limited to) the advertiser’s offered rate for the hotel room or other accommodation, the likelihood the offer will match the user’s accommodation search criteria, data we have collected on the likelihood an offer will be clicked and the CPC bids submitted by our advertisers (or CPC equivalent, as the case may be).
CPC levels play an important role in determining the prominence given to offers and their placement in our search results. Advertisers can analyze the number of referrals obtained from their advertisements on our marketplace and the consequent value generated from a referral based on the booking value they receive from users referred from our site, to determine the amount they are willing to pay. Generally, the higher the potential booking value or booking conversion generated by a Qualified Referral and the more competitive the bidding, the more an advertiser is willing to bid for an accommodation advertisement on our marketplace. This means that the levels of advertisers’ CPC bids generally reflect their view of the likelihood that each click on an offer will result in a booking by a user. We exclude from our marketplace auction offers where the CPC has been set to a de minimis level, as this typically denotes room inventory that the advertiser has withdrawn for some period of time from its active inventory on trivago.
By managing their CPC bids, their CPA campaigns and hotel room and other accommodation rates submitted on our marketplace, our advertisers can influence their own returns on investment and the volumes of referral traffic we generate for them. We believe that by providing services to help our advertisers, we can increase competition and create a more level playing field for our advertisers. By doing this, we aim to mitigate competitive disadvantages for smaller advertisers on our marketplace and to deliver more choice for our users.

36




Our strategy
We seek to enable people to better navigate the world of travel through products that make a vast number of accommodation options accessible and comparable. To that end, our strategy is focused on providing our users with the most valuable search experience, including the most comprehensive inventory and rate options from our OTA, hotel chain and individual hotel advertisers. We believe this capability has helped establish our position as a leading global accommodation search platform, which we strive to solidify through innovation and continuous improvement of our products, technology and algorithms.

Our customers
Customers that pay to advertise on trivago include:
OTAs, including large international players, as well as smaller, regional and local OTAs;
Hotel chains, including large multi-national hotel chains and smaller regional chains;
Individual hotels;
Providers of alternative accommodation, such as vacation rental or private apartments; and
Industry participants, including metasearch and content providers.
We generate the large majority of our Referral Revenue from OTAs. Certain brands affiliated as of the date hereof with our majority shareholder, Expedia Group, including Brand Expedia, Hotels.com, Orbitz, Travelocity, Hotwire, Wotif, Vrbo and ebookers, in the aggregate, accounted for 33% of our Referral Revenue for the year ended December 31, 2022. Booking Holdings and its affiliated brands, including Booking.com, Agoda and priceline.com, accounted for 49% of our Referral Revenue for the year ended December 31, 2022.
Nearly all of our agreements with advertisers, including our agreements with our largest advertisers, may be terminated upon prior notice of thirty days or less by either party. For more information on risks related to the concentration of our revenue and our relationship with our largest advertisers, see "Item 3: Key information - D. Risk factors".

Competition
We compete with other advertising channels for hotel advertisers’ marketing spend. These include traditional offline media and online marketing channels. In terms of user traffic, we compete on the basis of the quality of referrals, CPC rates and advertisers’ implied return on investment. While we compete with OTAs, hotel chains and independent hotels for user traffic, these parties also represent the key contributors to our revenue and supply of hotels and other accommodation.

37




Competition for users
We compete to attract users to our websites and apps to help them research and find hotels and other accommodation. Given our position at the top of the online search funnel, many companies we compete with are also our customers.
Our principal competitors for users include:
Online metasearch and review websites, such as Google Hotel Ads, Kayak, Skyscanner, Check24 and TripAdvisor;
Search engines, such as Bing, Google, Naver and Yahoo!;
Independent hotels and hotel chains, such as Accor, Hilton and Marriott;
OTAs, such as Booking.com, Ctrip, TUI, trip.com and Brand Expedia; and
Alternative accommodation providers, such as Airbnb and Vrbo.
Competition for advertisers
We compete with other advertising channels for hotel advertisers’ marketing spend. These include traditional offline media and online marketing channels. In terms of user traffic, we compete on the basis of the quality of referrals, CPC rates and advertisers’ implied return on investment.
Our principal competitors for advertisers’ marketing spend include:
Print media, such as local newspapers and magazines;
Other traditional media, such as TV and radio;
Search engines, such as Bing, Google, Naver and Yahoo!;
Online metasearch and review websites, such as Google Hotel Ads, Kayak, Skyscanner, Check24 and TripAdvisor;
Social networking services, such as Facebook and Twitter;
Websites offering display advertising;
Email marketing software and tools;
Online video channels, such as YouTube; and
Mobile app marketing.
Our employees and culture
We believe that our entrepreneurial corporate culture is a key ingredient to our success. It has been designed to reflect the fast-moving technology space in which we operate, as well as our determination to remain pioneers in our field. Our employees operate as entrepreneurs in their areas of responsibility, continuously striving for innovation and improvement for our customers. We strive to create strong, diverse teams that collaborate with each other in a respectful and efficient manner. Our employees exchange feedback regularly and regard failure as an opportunity to learn and improve approaches going forward. Cultural fit is a key part of our recruiting process, as we seek to hire individuals comfortable working in a flat organizational structure that rewards those who take initiative and continuously seek to understand and learn, take risks and innovate.

38




Seasonality
We experience seasonal fluctuations in the demand for our services as a result of seasonal patterns in travel. For example, searches and consequently our revenue are generally the highest in the first three quarters as travelers plan and book their spring, summer and winter holiday travel. Our revenue typically decreases in the fourth quarter. We generally expect to experience higher Return on Advertising Spend (ROAS) in the first and fourth quarter of the year as we typically expect to advertise less in the periods outside of high travel seasons. Seasonal fluctuations affecting our revenue also affect the timing of our cash flows.
We typically invoice once per month, with customary payment terms. Therefore, our cash flow varies seasonally with a slight delay to our revenue, and is significantly affected by the timing of our Advertising Spend. Changes in the relative revenue share of our offerings in countries and areas where seasonal travel patterns vary from those described above may influence the typical trend of our seasonal patterns in the future.

Intellectual property
Our intellectual property, including trademarks, is an important component of our business. We rely on confidentiality procedures and contractual provisions with suppliers to protect our proprietary technology and our brands. In addition, we enter into confidentiality and invention assignment agreements with our employees and consultants.
We have registered domain names for websites that we use in our business, such as www.trivago.com, www.trivago.de and www.trivago.co.uk. Our registered trademarks include: trivago, "Hotel? trivago", "trivago Rating Index", Youzhan, our "WABI" trivago logo and our trivago logo. These trademarks are registered in various jurisdictions.

Government regulation
trivago provides, receives and shares data and information with its users, advertisers and other online advertising providers and conducts consumer facing marketing activities that are subject to consumer protection laws in jurisdictions in which we operate, regulating unfair and deceptive practices. For example, the United States and the European Union, or EU (including at member state level), but also many other jurisdictions, are increasingly regulating commercial and other activities on the Internet, including the use of information retrieved from or transmitted over the Internet, the display, moderation and use of user-generated content, and are adopting new rules aimed at ensuring user privacy and information security as well as increasingly regulating online marketing, advertising and promotional activities and communications, including rules regarding disclosures in relation to the role of algorithms and price display messages in the display practices of platforms.
There are also new or additional rules regarding the taxation of digital products and services, the quality of products and services as well as addressing liability for third-party activities. Moreover, the applicability to the Internet of existing laws addressing issues such as intellectual property ownership and infringement is uncertain and evolving.
In particular, we are subject to an evolving set of data privacy laws. trivago is subject to the GDPR, which has been in effect since May 25, 2018 and which has recently led to the imposition of significant fines on various companies.
Following the UK’s exit from the European Union, the UK Government has transposed the GDPR into UK national law, creating the “UK GDPR”, which is complemented by the Data Protection Act 2018. However, the possible adoption of a data protection bill is currently under discussion in the UK Parliament, and may introduce significant changes to the UK data privacy regime. The Brazilian General Data Protection Law (LGPD), Federal Law no. 13,709/2018, is in force since September 18, 2020 and its penalties are enforceable since August 2021.The California Consumer Privacy Act of 2018 (CCPA) became effective in
39




January 2020 and is substantially amended by the California Consumer Privacy Rights Acts, which became operative in January 2023 and imposes new privacy requirements and rights for consumers in California. In the US, other state data privacy laws have or will also take effect, for example in Virginia as of January 1, 2023, Colorado and Connecticut as of July 1, 2023 and Utah as of December 31, 2023. Other substantial markets consider or are about to adopt data protection regulations. As a result, the data privacy regulatory landscape is becoming more and more fragmented, and such regulations risk being inconsistent or conflicting.
While we strive to monitor and comply with this complex and ever-changing patchwork of laws, a failure or perceived or alleged failure to comply with data privacy requirements in one of the jurisdictions where we operate, or target users may significantly harm our businesses. In addition, we could be adversely affected if data privacy regulations are expanded (through new regulation or through legal rulings) to require major changes in our business practices.
The growing complexity of the data protection landscape is exemplified by the regulation regarding international transfer of personal data, which is rapidly evolving and likely to remain uncertain for the foreseeable future. In particular, the GDPR regulates transfers of EU personal data to third countries that have not been found by the European Commission to provide adequate protection to such EU personal data, such as the United States. A considerable number of our service providers and hotels operate in such jurisdictions. In July 2020, the European Court of Justice (“CJEU”), invalidated the EU-U.S. Privacy Shield framework, which provided companies with a mechanism to comply with data protection requirements when transferring personal data from the EU to the United States. At present, companies can rely on the European Commission’s Standard Contractual Clauses to transfer personal data from Europe to the United States and other countries that have not been found to provide adequate protection to EU personal data. However, reliance on the Standard Contractual Clauses is now subject to enhanced due diligence on the data importer's national laws: a transfer impact assessment must be carried out for any transfers and supplementary measures may have to accompany the Standard Contractual Clauses for a transfer to be compliant. These changes are causing us to continually review our current compliance approach and may result in additional compliance costs or the inability to transfer personal data outside of the EU. The Trans-Atlantic Data Privacy Framework ("Framework"), currently under discussion between the United States and the European Union, might help reduce the complexity surrounding the transfer of personal data to the United States, but it is currently impossible for us to determine if this new legal instrument will be durable. On December 13, 2022, the European Commission launched the process to adopt a new adequacy decision regarding the Framework and submitted its draft decision to the European Data Protection Board ("EDPB"). Until the Framework is adopted by the EU, the legal uncertainty related to cross-border transfers of personal data, could harm our ability to transfer personal data outside of the EU, and could in turn harm our ability to provide, and our customers' ability to use, some of our services.
Many governmental authorities in the markets in which we operate are also considering, or are in the process of implementing, additional and potentially diverging legislative and regulatory proposals that would or will increase the level and complexity of regulation on Internet display, disclosure and advertising activities (for example, the EU's Data Governance Act, the EU's Digital Markets Act, the EU's Digital Services Act, the EU’s Data Act, the EU's NIS 2 Directive, ePrivacy Regulation and the European Commission's proposal Artificial Intelligence Act to regulate the development and commercial use of AI).
It is impossible to predict whether further new taxes or regulations will be imposed on our services and whether or how we might be affected. Increased regulation of the Internet could increase the cost of doing business or otherwise materially adversely affect our business, financial condition or results of operations. In addition, the application and interpretation of existing laws and regulations to our business is often uncertain, given the highly dynamic nature of our business and the sector in which trivago operates.

Technology and infrastructure
Data and proprietary algorithms
We process a large amount of information about user traffic and behavior, advertisers and direct connections into the databases of many of our advertisers. We believe it is central to the success of our business that we effectively capture and parse this data. To achieve this, we have developed proprietary algorithms that drive key actions across our platform, including search, listings and bidding tools. We continue to explore new ways to capture relevant data and feed this into our platform to further enhance the experience for both our users and advertisers.
Infrastructure
We host our platform in Germany and in addition use cloud services, which we believe offers us secure and scalable storage and processing power at manageable incremental expense. While much of the data we receive and capture is not sensitive, our data centers strive to be compliant with the highest security standards. Where required, our data centers are payment card industry (PCI) compliant and accordingly, it is our policy to store separately the limited amount of relevant sensitive data that we do capture. We have designed our websites, apps and infrastructure to be able to support high-volume demand.
Software
We develop our own software employing a rigorous iterative approach. This includes the proprietary algorithm underlying our search function, internal management tools, data analytics and advertiser tools.

trivago N.V. is the direct or indirect holding company of our subsidiaries. As of December 31, 2022, we do not own, directly or indirectly, any subsidiaries that we consider to be "significant".

D.    Property, plant and equipment
In June 2018, we moved into our headquarters located in Düsseldorf's media harbor. We currently occupy 21,258 square meters of office space, which has been certified with LEED core & shell Gold - representing a state-of-the-art workplace for trivago. The lease provides for a fixed ten-year term plus two renewal options, each for a term of five years. Initially, trivago N.V. was the sole tenant of the building and the building was, therefore, built to our specifications.
As a result of negotiations of our lease contract for the Campus in Düsseldorf, Germany, we signed an amendment to the contract, which became effective in January 2021. The agreement includes the return of unused office spaces and a corresponding reduction of rent, as well as the sale of certain fixed assets related to the space to the landlord. Please refer to Item 5A Operating Results- "Costs across multiple categories" below and "Note 7 - Leases" in the notes to our audited consolidated financial statements included in this annual report for further details.
We have additional 381 square meters of leased office space in Spain.

In the year ended December 31, 2022, Referral Revenue increased on a year-over-year basis by 54%, 45% and 48% in Americas, Developed Europe and Rest of World, respectively, compared to the same period in 2021.
We recorded a net loss for the year ended December 31, 2022 of €127.2 million, compared to net income for the year ended December 31, 2021 of €10.7 million, representing a decrease of €137.9 million from 2021 to 2022.
Adjusted EBITDA for the years ended December 31, 2022 and 2021 was €107.5 million and €34.6 million, respectively. Adjusted EBITDA is a non-GAAP financial measure, and we therefore direct you to “Item 5: Operating and financial review and prospects - G. Non-GAAP financial measures” for an additional description of Adjusted EBITDA and a reconciliation of Adjusted EBITDA to net income/(loss).
Key factors affecting our financial condition and results of operations
How we earn and monitor revenue
We earn substantially all of our revenue when users of our websites and apps click on hotel offers or advertisements in our search results and are referred to one of our advertisers. We call this our Referral Revenue. Each advertiser determines the amount that it wants to pay for each referral by bidding for advertisements on our marketplace. We also offer the option for our advertisers to participate in our marketplace on a cost-per-acquisition, or CPA, basis. We continue to onboard additional advertisers to the CPA model. See “Item 4: Information on the company - B. Business overview - Marketplace."
We also earn revenue by offering our advertisers B2B solutions, such as display advertisements, white label services, and subscription fees earned from advertisers for the trivago Business Studio PRO Package, and we are in the process of discontinuing projects, such as display advertisements and white label services, in 2023.
Key metrics we use to monitor our revenue include the number of Qualified Referrals we make, the revenue we earn for each Qualified Referral, or RPQR, and our Return on Advertising Spend, or ROAS.

Qualified Referrals
We use the term “referral” to describe each time a visitor to one of our websites or apps clicks on a hotel offer in our search results and is referred to one of our advertisers. We charge our advertisers for each referral mostly on a CPC basis.
Since a visitor may generate several referrals on the same day, but typically intends to only make one booking on a given day, we track and monitor the number of Qualified Referrals from our platform. We define a "Qualified Referral" as a unique visitor per day that generates at least one referral. For example, if a single visitor clicks on multiple accommodation offers in our search results in a given day, they count as multiple referrals, but as only one Qualified Referral. While we charge advertisers for every referral, we believe that the Qualified Referral metric is a helpful proxy for the number of unique visitors to our site with booking intent, which is the type of visitor our advertisers are interested in and which we believe supports bidding levels in our marketplace.
We believe the primary factors that drive changes in our Qualified Referral levels are the number of visits to our websites and apps, the booking intent of our visitors, the number of available accommodations on our search platform, content (the quality and availability of general information, reviews and pictures about the hotels), hotel room prices (the price of accommodation as well as the number of price sources for each accommodation), hotel ratings, the user friendliness of our websites and apps and the degree of customization of our search results for each visitor. In the short term, our Qualified Referral levels are also heavily impacted by changes in our investment in Advertising Spend, as we rely on advertisements to attract users to our platform. Ultimately, we aim to increase the number and booking conversion of Qualified Referrals we generate by focusing on making incremental improvements to each of these parameters. In addition to continuously seeking to expand our network in hotel advertisers and alternative accommodations, we partner with such hotels or service providers to improve content, and we constantly test and improve the features of our websites and apps to improve the user experience, including our interface, user friendliness and personalization for each visitor.
The following table sets forth the number of Qualified Referrals for our reportable segments for the periods indicated:

Developed Europe 139.0 119.6 16 %
Rest of World 85.3 80.0 %
Total 311.6 282.2 10 %
Revenue per Qualified Referral (RPQR)
We use average Revenue per Qualified Referral, or RPQR, to measure how effectively we convert Qualified Referrals to revenue. RPQR is calculated as Referral Revenue divided by the total number of Qualified Referrals in a given period. Alternatively, RPQR can be separated into its price and volume components and calculated as follows:
RPQR = RPR x click-out rate

where
RPR = revenue per referral
click-out rate = referrals / Qualified Referrals

45




RPQR is determined by the CPC bids or CPA bids our advertisers submit on our marketplace. CPC bids submitted by our advertisers (or a CPC equivalent in the case of advertisers billed on a CPA basis) play an important role in determining the prominence given to offers and their placement in our search results. Advertisers can analyze the number of referrals obtained from their advertisements on our marketplace and the consequent value generated from a referral based on the booking value they receive from users referred from our site to determine the amount they are willing to bid. Accordingly, the bidding behavior of our advertisers is influenced by the rate at which our Qualified Referrals result in bookings on their websites, or booking conversion, and the amount our advertisers obtain from Qualified Referrals as a result of hotels and other accommodation booked on their sites, or booking value. The quality of the traffic we generate for our advertisers increases when aggregate booking conversion and/or aggregate booking value increases. We estimate overall booking conversion and booking value from data voluntarily provided to us by certain advertisers to better understand the drivers in our marketplace and, in particular, to gain insight into how our advertisers manage their advertising campaigns. Assuming unchanged dynamics in the market beyond our marketplace, we would expect that the higher the potential booking value or conversion generated by a Qualified Referral and the more competitive the bidding, the more an advertiser is willing to bid for a hotel advertisement on our marketplace. The dynamics in the market beyond our marketplace are not static, and we believe that our advertisers continuously review their Advertising Spend on our platform and on other advertising channels, and continuously seek to optimize their allocation of their spending among us and our competitors.
RPQR is a key financial metric that indicates the quality of our referrals, the efficiency of our marketplace and, as a consequence, how effectively we monetize the referrals we provide our advertisers. Furthermore, we use RPQR to help us detect and analyze changes in market dynamics.

Return on Advertising Spend (ROAS)
We track the ratio of our Referral Revenue to our advertising expenses, or ROAS. We believe that ROAS is an indicator of the effectiveness of our advertising, and it is our primary operating metric. Historically, we believe that our advertising has been successful in generating additional revenue. We invest in many kinds of marketing channels, such as TV, search engine marketing, display and affiliate marketing, email marketing, social media, online video, mobile app marketing, content marketing, sponsorship and endorsement.
Our ROAS by reportable segment for the years ended December 31, 2022 and 2021 was as follows:
Year ended December 31, 
ROAS by segment (unaudited)20222021

Developed Europe 158.6 %153.0 %
Rest of World 188.8 %202.9 %
Consolidated ROAS164.4 %156.3 %
In the year ended December 31, 2022, consolidated ROAS increased to 164.4% compared to 156.3% in the same period in 2021. ROAS increased by 15.5ppts and 5.6ppts in Americas and Developed Europe, respectively, while it decreased by 14.1ppts in RoW compared to the same period in 2021. The ROAS increase in Americas and Developed Europe was mainly driven by the increase in Referral Revenue resulting from higher RPQR and Qualified Referrals, which more than offset the increase in Advertising Spend. The decrease in RoW was driven by the significant increase in Advertising Spend, particularly in Japan, considering a muted level of Advertising Spend in 2021 due to COVID-19 related restrictions.
Advertising Spend increased by 39.9%, 40.0% and 59.6% in Americas, Developed Europe and RoW, respectively, compared to the same period in 2021. Advertising Spend increased across all segments throughout the year in response to the increase in global travel demand compared to the same period in 2021.

Marketplace dynamics
Our advertisers regularly adjust the CPC and CPA bids they submit on our marketplace to reflect the levels of referrals, customers, bookings or revenue and profit they intend to achieve with their marketing spend on our platform. In recent years, we have observed a number of factors that can influence their bidding behavior on our marketplace, including:
The fees advertisers are willing to pay based on how they manage their advertising costs and their targeted return on investment;
Our advertisers' testing of their bidding strategies and the extent to which they make their inventories available on our marketplace;
Responses of advertisers to elevated levels of volatility on our marketplace;
Advertiser competition for the placement of their offers; and
Our advertisers’ response to changes made to our marketplace.
Recent and ongoing trends in our business
The following recent and ongoing trends have contributed to the results of our consolidated operations, and we anticipate that they will continue to impact our future results.
Rebound in travel demand as the world emerged from the COVID-19 pandemic
In 2022, almost all COVID-19 related measures were phased out, and as a result, we benefited from a sharp rebound in travel activity and strong advertiser bidding dynamics across most of our core markets. The effects of the COVID-19 pandemic on travel behavior also appeared to have receded as large-scale vaccinations and mass recovery from COVID-19 infections gave many travelers the confidence to travel as they had prior to the pandemic. As a result, we believe that travel seasonality going into 2023 will be more in line with what we experienced prior to the pandemic.
While our business improved significantly as the world emerged from the COVID-19 pandemic, our revenue levels remained significantly below those in 2019. We believe this is in large part attributable to the fact that we almost completely ceased advertising on television in 2020 and resumed such advertising at reduced levels in 2021 and 2022. As a result, we believe that in 2022, we have not benefited in the same way from prior campaigns as had been the case in the past, and we expect that this will continue to be the case in the coming years. We anticipate that we will need to invest in television advertising campaigns in the next years to grow the volume of direct traffic to our platform.
Macroeconomic and geopolitical environment
The war in Ukraine, supply chain issues and rising interest rates have led to significantly increased inflation that we expect to continue to have an impact on the travel market going forward. Average booking values continued to be positively impacted by increased average daily hotel rates and were, as a result, significantly higher compared to the prior year period. This was a key driver of our financial performance in 2022, which is reflected in the increase in RPQR in 2022. We have observed the first signs of consumers attempting to mitigate increasing average daily hotel rates by, for example, shortening their length of stay or looking for cheaper destinations and accommodations.
Against this backdrop, we believe travelers will have an increased need to compare prices amidst rising inflation. In view of these factors, we decided to focus primarily on further improving our core accommodation price comparison product to drive higher user retention. As a part of this initiative, we conducted a large-scale full market test in five test markets, including Brazil, starting in the third quarter of 2022. While this led to a significant decrease in click-outs and Qualified Referrals during the test, overall booking volume in our segment Americas increased. Moreover, as a result of the shift in internal priorities, we decided to discontinue certain projects and products, such as our display ads and Weekend product, and as a result, we conducted headcount reductions in these areas during the year.
48




In addition, the ongoing military conflict between Ukraine and Russia had a negative impact on our business. As a result of the conflict, on March 2, 2022, we discontinued our local Russian platform, which, when considered alone, had an immaterial impact on our total revenue and ROAS contribution in 2022. Our Eastern European platforms, however, have seen a significant reduction in traffic volumes and continued to be negatively impacted during 2022, negatively impacting our business in RoW. We also saw an initial drop in traffic volumes in some of our Western European markets after the invasion but traffic volumes have mostly recovered to pre-conflict levels.
Impairments of intangible assets and goodwill
As a result of the continued deterioration of macroeconomic conditions, including rising interest rates, increased inflation and more uncertainty in respect of the overall economic environment, we performed intangible assets and goodwill impairment analyses during the second and third quarters of 2022, as a result of which we recorded impairment charges totaling €184.6 million. For more information on the impairment charge, see "Note 8 - Goodwill and intangible assets, net" in the notes to our audited consolidated financial statements included in this annual report.
Material litigation
On April 22, 2022, the Australian Federal Court issued a judgment in the proceeding brought by the Australian Competition and Consumer Commission (ACCC) against us. The Australian Federal Court ordered us to pay a penalty of €29.6 million (AUD44.7 million) and to cover the ACCC's costs arising from the proceeding. The court also issued an injunction enjoining us from engaging in misleading conduct of the type found by the Australian Federal Court to be in contravention of the Australian Consumer Law. The decision of the Australian Federal Court had a significant negative impact on our operating expenses, resulting in a negative impact on operating expenses of €20.7 million in 2022. Due to the size and unusual nature of the accrual relating to the judgement of the Australian Federal Court and its distorting effect on the understanding of our underlying business developments, it is excluded when calculating Adjusted EBITDA for 2022. For more information on our definition of Adjusted EBITDA, see "Item 5: Operating and financial review and prospects - H. Non-GAAP financial measures."
Mobile products
Travelers increasingly access the Internet from multiple devices, including desktop computers, smartphones and tablets. We continue to develop our websites and apps to further enhance our hotel search experience across all devices. We offer responsive mobile websites and several apps that allow travelers to use our services from smartphones and tablets running on Android and iOS. In the year ended December 31, 2022, our revenue share from mobile websites and apps continued to exceed 60%.
Visitors to our search platform via mobile phones and tablets generally result in bookings for our advertisers at a lower rate than visitors to our platform via desktop. We believe this is due to a general difference in the usage patterns of mobile phones and tablets. We believe many visitors use mobile phones and tablets as part of their search process, but prefer finalizing hotel selections and completing their bookings on desktop websites. This may be due in part to users generally finding the booking completion processes, including entering payment information, somewhat easier or more secure on a desktop than on a mobile device. We believe that over time and as more travelers become accustomed to mobile transactions, this sentiment may shift.
We have historically had, and currently have, a single price structure for referrals from both desktop and mobile. We may choose to adopt a differentiated pricing model between mobile and desktop applications, which would likely lead to an increase in desktop revenue share, as the pricing for desktop applications would increase due to higher conversion rates, while the pricing for apps on mobile and tablets would likely decrease. We do not expect this to have a material impact on revenue, as long as there are sufficient active participants on both desktop and mobile to ensure our marketplace functions effectively, as we believe that the current bids advertisers place on our CPC-based bidding system reflect the overall efficacy of the combined desktop and mobile prices they receive.
49




Advertiser structure
We continue to generate most of our Referral Revenue from a limited number of OTAs. Certain brands affiliated as of the date hereof with our majority shareholder, Expedia Group, including Brand Expedia, Hotels.com, Orbitz, Travelocity, Hotwire, Wotif, Vrbo and ebookers, in the aggregate, accounted for 33% of our Referral Revenue for the year ended 2022. Booking Holdings and its affiliated brands, Booking.com, Agoda and priceline.com accounted for 49% of our Referral Revenue for the year ended 2022. Although we believe we will ultimately receive a portion of the additional booking value we generate for our advertisers, the fact that a significant portion of our Referral Revenue is generated from brands affiliated with Expedia Group and Booking Holdings can permit them to obtain the same or increased levels of referrals, customers, bookings or revenue and profit at lower cost.

Revenue
Our total revenue in the year ended December 31, 2022, consisted of Referral Revenue of €521.8 million and other revenue of €13.2 million.
Total revenue for the year ended December 31, 2022 was €535.0 million, representing an increase of €173.6 million, or 48.0%, compared to the year ended December 31, 2021. Revenue from related parties for the year ended December 31, 2022 increased by €81.9 million, or 89.7%, compared to the year ended December 31, 2021, while revenue from third parties increased by €91.6 million, or 33.9% for the same period.
Referral revenue for the year ended December 31, 2022 was €521.8 million, representing an increase of €172.4 million, or 49.3%, compared to the year ended December 31, 2021. This increase was mainly driven by an increase in RPQR and Qualified Referrals across all segments, compared to the year ended December 31, 2021.
The increase in RPQR in the twelve months ended December 31, 2022, was mainly driven by the significant increase in bidding levels (mainly driven by better booking conversion and higher average booking values) and by a positive foreign exchange rate impact resulting from the strengthening of the U.S. dollar against the euro throughout the year 2022.
Qualified Referrals increased across all regions in the first half of 2022 due to the increase in traffic volumes, reflecting the easing of COVID-19 related mobility restrictions, compared to the same period in 2021. This increase was partly offset in the second half of 2022 by the market test in Brazil and increased competition to acquire traffic in Developed Europe.

The breakdown of Referral Revenue by reportable segment is as follows:
Year ended December 31,% Change
(in millions)202220212022 vs 2021

Developed Europe 237.7 163.7 45 %
Rest of World 67.7 45.6 48 %

Referral Revenue in Americas in the year ended December 31, 2022, increased by €76.3 million, or 54.5%, compared to the year ended December 31, 2021. The year-over-year increase in Referral Revenue was mainly driven by an increase in RPQR and Qualified Referrals.
In Americas, RPQR increased by €0.78, or by 45.9% in the year ended December 31, 2022, compared to the same period in 2021, primarily due to higher bidding levels (mainly driven by higher average booking values and better booking conversion). RPR increased by 47.3%, compared to the year ended December 31, 2021. Qualified Referrals increased significantly in the first half of 2022, primarily due to the increase in traffic volumes resulting from the easing of COVID-19 related mobility restrictions, but were partly offset by a large-scale market test in Brazil in the second half of 2022.
Referral Revenue in Developed Europe in the year ended December 31, 2022, increased by €74.0 million, or 45.2%, compared to the year ended December 31, 2021, mainly driven by an increase in Revenue per Qualified Referral and Qualified Referrals.
In Developed Europe, RPQR increased by €0.34, or by 24.8% in the year ended December 31, 2022, compared to the year ended December 31, 2021, due to higher bidding levels (mainly driven by better booking conversion and higher average booking values) throughout 2022. RPR increased by 25.7%, compared to the year ended December 31, 2021. Qualified Referrals increased significantly in the first half of 2022, primarily driven by the recovery of travel demand, but were partly offset in the second half of 2022 due to increased competition to acquire traffic in some of our markets.
Referral Revenue in RoW in the year ended December 31, 2022, increased by €22.1 million, or 48.5%, compared to the year ended December 31, 2021, which was mainly driven by an increase in Revenue per Qualified Referral and Qualified Referrals.
In RoW, RPQR increased by €0.22, or 38.6% in the year ended December 31, 2022 compared to the year ended December 31, 2021, due to higher bidding levels (mainly driven by higher average booking values and better booking conversion) throughout 2022. RPR increased by 39.3% compared to the year ended December 31, 2021. Qualified Referrals increased in 2022, particularly in Japan, reflecting the easing of COVID-19 related mobility restrictions. This increase was partly offset, mostly due to traffic declines in certain Asian markets, considering the pent-up demand in the comparative period in 2021, as well as declines in Russia and Central Eastern European markets resulting from the war in Ukraine.
Cost of revenue and expenses
Cost of revenue
Our cost of revenue consists primarily of our third-party cloud-related service provider expenses and third-party data center expenses, depreciation expense for self owned data center, personnel-related expenses and share-based compensation for our data center operations staff and our customer service team.
Cost of revenue was €12.7 million for the year ended December 31, 2022, and increased by €1.2 million, or 10%, compared to the year ended December 31, 2021. The increase was mainly driven by higher cloud-related service provider costs and higher personnel related costs, partly offset by lower data center-related depreciation expenses.
52




Selling and marketing
Selling and marketing is divided into advertising expense and other selling and marketing expenses, as well as share-based compensation expense.
Advertising expense consists of fees that we pay for our various marketing channels like TV, search engine marketing, display and affiliate marketing, email marketing, online video, app marketing, content marketing, and sponsorship and endorsement.
Other selling and marketing expenses include personnel-related expenses for our marketing, sales and account management teams, as well as production costs for our TV spots and other marketing material, and other professional fees such as market research costs.

Selling and marketing expenses for the year ended December 31, 2022, increased by €92.8 million, or 37.2%, compared to the year ended December 31, 2021, primarily driven by significant increases in Advertising Spend across all segments.
Advertising Spend increased by €93.7 million, or 41.9%, in the year ended December 31, 2022, compared to the year ended December 31, 2021. We increased our Advertising Spend to €131.6 million, €149.8 million and €35.9 million in Americas, Developed Europe and Rest of World, respectively, compared to €94.1 million, €107.0 million and €22.5 million, respectively, in the year ended December 31, 2021. Advertising Spend was increased across all segments throughout the year in response to the increase in global travel demand.
Other selling and marketing expenses excluding share-based compensation for the year ended December 31, 2022 decreased by €0.6 million, or 2.4%, compared to the year ended December 31, 2021. The decrease was primarily driven by lower television advertisement production costs, partly offset by higher expenses incurred to acquire traffic and higher digital services taxes.
53




Technology and content
Technology and content expense consists primarily of expenses for technology development, product development and hotel search personnel and overhead, depreciation and amortization of technology assets including hardware, purchased and internally developed software and other professional fees (primarily licensing and maintenance expense), including share-based compensation expense.

Technology and content expense for the year ended December 31, 2022 increased by €2.5 million, or 4.8%, compared to the year ended December 31, 2021, mainly due to higher personnel-related costs and higher professional fees and other expenses.
Personnel-related costs for the year ended December 31, 2022 increased by €2.4 million, or 8.0%, mainly due to higher salaries and direct employee benefits compared to the year ended December 31, 2021, partly offset by lower headcount and increased capitalization of our developers' salaries.
Professional fees and other expenses increased by €2.2 million, or 17.7%, mainly due to an impairment of capitalized software assets in the second quarter of 2022 and the non-recurrence of a gain realized in the first quarter of 2021 on the modification of the lease for our Düsseldorf campus, see "Costs across multiple categories" below.
These increases were partly offset by lower depreciation expense and lower share-based compensation expense.
General and administrative
General and administrative expense consists primarily of personnel-related costs including those of our executive leadership, finance, legal and human resource functions, as well as professional fees for external services including legal, tax and accounting. It also includes other overhead costs, depreciation and share-based compensation.

The increase in professional fees and other expenses for the year ended December 31, 2022 was mostly driven by the recognition of additional expense of €20.7 million, representing the incremental portion not
54




covered by provisions we had previously established in relation to the proceeding brought by the Australian Competition and Consumer Commission (ACCC) against us.
Costs across multiple categories
In the year ended December 31, 2021, we reduced our office space in Düsseldorf and recorded a €1.2 million gain on the campus lease modification. The non-recurrence of this gain led to an increase of technology and content expense by €0.7 million, general and administrative expense by €0.3 million and selling and marketing expense by €0.2 million in the year ended December 31, 2022, compared to the year ended December 31, 2021.
Amortization of intangible assets
Amortization of intangible assets was €0.1 million in both the year ended December 31, 2022 and in the year ended December 31, 2021, as we amortize intangible assets acquired through the weekengo GmbH acquisition.
Impairment of intangible assets and goodwill
We recorded cumulative impairment charges of €184.6 million in the year ended December 31, 2022. There was no impairment charge recorded in the year ended December 31, 2021. See "Note 8 - Goodwill and intangible assets, net" in the notes to our audited consolidated financial statements included in this annual report for further details.
Operating income/(loss)
Our operating loss was €120.3 million for the year ended December 31, 2022 compared to an operating income of €10.1 million for the year ended December 31, 2021. The decrease was mainly driven by the impairment charges recorded in the second and third quarters of the year ended December 31, 2022 totaling €184.6 million, and the recognition of €20.7 million of additional expense relating to the penalty imposed on us by the Australian Federal Court in the first quarter of 2022. These were partly offset by the recovery of travel demand, resulting in an increase in Referral Revenue of €172.4 million and in Advertising Spend of €93.7 million.
Other income/(expense)
Other income for the year ended December 31, 2022 was €15 thousand compared to other income of €13.2 million for the year ended December 31, 2021, as we received a €12.0 million COVID-19 subsidy from the German government in the year ended December 31, 2021.

Income tax expense was €6.6 million in the twelve months ended December 31, 2022, compared to €12.6 million in the twelve months ended December 31, 2021. Our effective tax rate was (5.5)% in 2022, compared to 54.0% in 2021. Non-deductible share-based compensation of (pre-tax) €15.3 million in 2022 and €17.3 million in 2021 had an impact on the effective tax rates of (4.0)% and 23.1% in the years ended December 31, 2022 and 2021, respectively. Non-deductible impairment expenses on goodwill of (pre-tax) €104.6 million had an impact on the effective tax rate of (27.2)% in the year ended December 31, 2022. The tax impact of the movement in uncertain tax position of €6.3 million had an impact on the effective tax rate of (5.2)% in the year ended December 31, 2022,
The details on the movement in valuation allowance are included in "Note 10 - Income taxes" in the notes to our audited consolidated financial statements included in this annual report. Other differences relate to one-off items during the year, such as non-deductible expenses which are individually insignificant.

Quantitative and qualitative disclosures about market risk
Market risk is the potential loss from adverse changes in interest rates, foreign exchange rates and market prices. Our exposure to market risk includes our cash, accounts receivable, intercompany receivables, investments and accounts payable. We manage our exposure to these risks through established policies and procedures. Our objective is to mitigate potential income statement, cash flow and market exposures from changes in interest and foreign exchange rates.
Interest rate risk
We did not experience any significant impact from changes in interest rates and had no outstanding loans during the year ended December 31, 2022.
Foreign exchange risk
We conduct business in many countries throughout the world. Because we operate in markets globally, we have exposure to different economic climates, political arenas, tax systems and regulations that could affect foreign exchange rates. Our primary exposure to foreign currency risk relates to transacting in foreign currency and recording the activity in euro. A large portion of our advertising expenses are incurred in the local currency of the particular geographic market in which we advertise, with a significant amount incurred in U.S. dollar. The vast majority of our revenue is denominated in euro. Changes in exchange rates between the functional currency of our consolidated entities and these other currencies will result in transaction gains or losses, which we recognize in our consolidated statements of operations. Our foreign exchange risk relates primarily to the exchange rate between the U.S. dollar and the euro.
Changes in foreign exchange rates can amplify or mute changes in the underlying trends in our revenue and RPQR. Although we have relatively little direct foreign currency translation with respect to our revenue, we believe that our advertisers’ decisions on the share of their booking revenue they are willing to pay to us are based on the currency in which the hotels being booked are priced. Accordingly, we have observed that advertisers tend to adjust their CPC bidding based on the relative strengthening or weakening of the euro as compared to the local functional currency in which the booking with our advertisers is denominated.
Future net transaction gains and losses are inherently difficult to predict as they are reliant on how the multiple currencies in which we transact fluctuate in relation to the functional currency of our consolidated entities, the relative composition and denomination of current assets and liabilities for each period, and our effectiveness at forecasting and managing, through balance sheet netting, such exposures. As an example, if the foreign currencies in which we hold net asset balances were to depreciate by 10% against the euro and other currencies in which we hold net liability balances were to appreciate by 10% against the euro, we would recognize foreign exchange losses of €1.4 million based on the net asset or liability balances of our foreign denominated cash, accounts receivable and accounts payable balances as of December 31, 2022. As the net composition of these balances fluctuate frequently, even daily, as do foreign exchange rates, the example loss could be compounded or reduced significantly within a given period.
During the year ended December 31, 2022 we had net foreign exchange rate losses of €0.2 million compared to gains of €1.6 million in the year ended December 31, 2021.
Concentration of credit risk
Our business is subject to certain risks and concentrations including dependence on relationships with our advertisers, dependence on third-party technology providers, and exposure to risks associated with online commerce security. Our concentration of credit risk relates to depositors holding our cash and customers with significant accounts receivable balances.
Our customer base includes primarily OTAs, hotel chains and independent hotels. We perform ongoing credit evaluations of our customers and maintain allowances for potential credit losses. We generally do not require collateral or other security from our customers. Expedia Group and affiliates represented 32% of our total revenue for the year ended December 31, 2022 and 49% of total accounts receivable as of
56




December 31, 2022. Booking Holdings and its affiliates represented 49% of our revenue for the year ended December 31, 2022 and 30% of total accounts receivable as of December 31, 2022.

B.    Liquidity and capital resources
For the year ended December 31, 2022, total cash, cash equivalents and restricted cash decreased by €7.8 million to €248.9 million, of which €248.6 million were included in cash and cash equivalents and €0.3 million in short-term restricted cash in the balance sheet. The decrease in total cash, cash equivalents and restricted cash was mainly driven by negative cash flows from investing and financing activities, partly offset by positive cash flows from operating activities.
Our known material liquidity needs for periods beyond the next twelve months are described below in “Item 5: Operating and financial review and prospects - F. Tabular disclosure of contractual obligations.” We believe that our cash from operations, together with our cash balance are sufficient to meet our ongoing capital expenditures, working capital and other capital needs.
The following table summarizes our cash flows for the years ended December 31, 2022 and 2021:
Year Ended December 31,
 (in millions)20222021
Cash flows provided by operating activities66.3 32.5 
Cash flows provided by/(used in) investing activities(54.9)10.0 
Cash flows provided by/(used in) financing activities(19.6)1.1 
Cash Flows Provided by Operating Activities
For the year ended December 31, 2022, net cash provided by operating activities increased by €33.7 million to €66.3 million. This increase was mainly driven by the adjustment of non-cash items totaling €188.1 million included in the period net loss and positive changes in operating assets and liabilities of €5.4 million. Non-cash items reconciled from net loss of €127.2 million include the intangible assets and goodwill impairment charge of €184.6 million, share-based compensation of €15.3 million and depreciation of €6.0 million, partly offset by a reduction of deferred income taxes of €19.7 million.
The net loss for the year ended December 31, 2022 includes the recognition of €20.7 million additional expense, representing the incremental portion not previously recognized of the total penalty imposed on us by the Australian Federal Court in the proceeding brought by the ACCC against us. The total penalty imposed was paid in the second quarter of 2022.
Positive changes in operating assets and liabilities were primarily due to an increase in taxes payable of €10.6 million, and in accounts payable of €5.3 million. These were partly offset by an increase in accounts receivable of €10.1 million resulting mostly from higher revenues in the fourth quarter of 2022 compared to same period in 2021.
Cash Flows Used in Investing Activities
For the year ended December 31, 2022, cash used in investing activities was €54.9 million, primarily driven by the purchase of €50.0 million in term deposits, an investment of €5.9 million in an equity-method investee and a €4.0 million net cash outflow related to capital expenditures, including internal-use software and website development. These were partly offset by proceeds from sales and maturities of investments of €5.0 million.
Cash Flows Used in Financing Activities
For the year ended December 31, 2022, cash used in financing activities was €19.6 million, primarily driven by the purchase of treasury stock for €19.6 million, which includes the purchase of 20,000,000 Class A shares from Peter Vinnemeier, one of our founders, for €19.3 million in November 2022.

E.    Critical Accounting Policies and Estimates
Critical accounting policies and estimates are those that we believe are important in the preparation of our consolidated financial statements because they require that we use judgment and estimates in applying those policies. We prepare our consolidated financial statements and accompanying notes in accordance with generally accepted accounting principles in the United States. Preparation of the consolidated financial statements and accompanying notes requires that we make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the date of the consolidated financial statements, as well as revenue and expenses during the periods reported. We base our estimates on historical experience, where applicable, and other assumptions that we believe are reasonable under the circumstances. Actual results may differ from our estimates under different assumptions or conditions.
There are certain critical estimates that we believe require significant judgment in the preparation of our consolidated financial statements. We consider an accounting estimate to be critical if:
It requires us to make an assumption because information was not available at the time or it included matters that were highly uncertain at the time we were making the estimate; and
Changes in the estimate or different estimates that we could have selected may have had a material impact on our financial condition or results of operations.
For more information on each of these policies, see "Note 2 - Significant accounting policies" in the notes to our audited consolidated financial statements included in this annual report for further details. We discuss information about the nature and rationale for our critical accounting estimates below.
Leases
We have operating leases for office space and office equipment. Operating lease right-of-use ("ROU") assets and lease liabilities are recognized at commencement date based on the present value of lease payments over the lease term.
Given the rate implicit in our leases is not typically readily determinable, we have to estimate the Incremental Borrowing Rate ("IBR") to be used as the discount rate in order to measure the present value of future lease payments.
In January 2021, we amended the operating lease agreement for office space in our corporate headquarters, whereby the landlord granted us partial termination of the lease related to certain floor spaces. This amendment was treated as a lease modification. See "Note 7 - Leases" in the notes to our audited consolidated financial statements included in this annual report for further details.
The IBR was used to derive gain or loss on lease modification and adjustments to operating lease ROU assets and lease liabilities as of the effective date of the lease modification. Estimating the IBR requires assessing a number of inputs including an estimated synthetic credit rating, collateral adjustments and interest rates. Selecting different inputs for this estimation may result in different gain or loss on lease modification and adjustments to operating lease ROU assets and lease liabilities. The selected IBR would have to change by more than 70 basis points to result in a materially different post-modification operating lease ROU assets and lease liabilities balance. The gain or loss recognized on lease modification would not have been materially different.
58




Recoverability of goodwill and indefinite-lived intangible assets
We assess goodwill and indefinite-lived assets, neither of which are amortized, for impairment annually as of September 30, or more frequently, if events and circumstances indicate that an impairment may have occurred.
For the year ended December 31, 2022, we performed two quantitative impairment assessments. A goodwill and indefinite-lived intangible assets impairment charge of €84.2 million was recorded for the quarter ended June 30, 2022. A further impairment charge of €100.4 million was recorded for the quarter ended September 30, 2022 while performing our annual impairment test.
Goodwill is assigned to our three reporting units, which correspond to our three operating segments (Americas, Developed Europe and Rest of World), on the basis of their relative fair values. The fair value of each reporting unit was estimated using a blended analysis of the present value of future discounted cash flows and market valuation approach.
The discounted cash flow model requires significant estimates, including our weighted average cost of capital, revenue growth rates, profitability of our business and long-term rate of growth. Changes in these estimates and assumptions could materially affect the estimated fair value of each reporting unit that could result in an impairment charge to reduce the carrying value of goodwill, which could be material to our financial position and results of operations.
The significant estimates within the market valuation approach include identifying similar companies with comparable business factors, such as size, growth, profitability, risk and return on investment, assessing comparable revenue and operating income multiples and the control premium applied in estimating the fair value of the reporting unit.
Indefinite-lived intangible assets consists of trade name, trademarks, and domain names. We base our measurement of the fair value using the relief-from-royalty method. This method assumes that the trade name and trademarks have value to the extent that their owner is relieved of the obligation to pay royalties for the benefits received from them. This method requires us to estimate future revenue for the brand, the appropriate royalty savings rate and an applicable discount rate.
The most significant assumptions used in our current year analyses to determine the fair value of the reporting units were our weighted average cost of capital ("WACC") and long-term growth rate. The most significant assumptions used in determining the fair value of our indefinite-lived intangible assets were the royalty savings rate and the discount rate. The use of different estimates or assumptions in determining the fair value of our goodwill and indefinite-lived intangible assets may result in different values, which could result in an impairment, or in the period in which an impairment is recognized, could result in a materially different impairment charge.
As a result of the second quarter assessment, we recorded an impairment charge of €57.0 million to our goodwill balance in the Developed Europe reporting unit. We did not record any impairment to our Americas reporting unit as the fair value was assessed to be higher than its carrying value and there was no goodwill allocated to the Rest of World reporting unit. The percentage by which fair value exceeded carrying value for our Americas reporting unit as of June 30, 2022 was 50%. Assuming all other assumptions remain constant, if the selected WACC increased by 100 basis points, we would have incurred an additional €13.6 million goodwill impairment in the Developed Europe reporting unit. An increase of 500 basis points to the selected WACC in the Americas reporting unit would still not result in an impairment. Assuming all other assumptions remain constant, if the selected long-term growth rate decreased by 50 basis points, we would have incurred an additional €2.7 million goodwill impairment in the Developed Europe reporting unit. The selected long-term growth rate for the Americas reporting unit was not sensitive for the impairment test performed as of June 30, 2022.
Due to further deteriorating macroeconomic conditions present during the third quarter as compared to the second quarter of 2022, for our annual impairment test as of September 30, 2022, we performed another quantitative assessment. The annual impairment test was performed using revised data and estimates to the discounted cash flow model and market value approach incorporating the further
59




deteriorating macroeconomic conditions. We recorded a further impairment charge of €47.6 million to our goodwill balance in the Developed Europe reporting unit. We did not record any impairment to our Americas reporting unit as the fair value was assessed to be higher than its carrying value and there was no goodwill allocated to the Rest of World reporting unit. The percentage by which fair value exceeded carrying value for our Americas reporting unit as of September 30, 2022 was 8%. Assuming all other assumptions remain constant, if the selected WACC increased by 100 basis points, we would have incurred an additional €5.5 million goodwill impairment in the Developed Europe reporting unit. The WACC would need to increase by approximately 400 basis points to incur an impairment in the Americas reporting unit. The selected long-term growth rates were not sensitive for the impairment test performed as of September 30, 2022.
We recorded impairment charges of €27.2 million and €52.8 million to our indefinite-lived intangible assets in the quarters ended June 30, 2022 and September 30, 2022, respectively. Assuming all other assumptions remain constant, a decrease of 100 basis points in the royalty savings rate would have resulted in a further impairment charge of €35.6 million and €22.4 million during the June 30, 2022 and September 30, 2022 impairment tests, respectively. Assuming all other assumptions remain constant, an increase of 100 basis points in the selected discount rate would have resulted in a higher impairment charge of €11.3 million and €4.0 million during the June 30, 2022 and September 30, 2022 analyses, respectively.
The amounts of goodwill allocated to the Developed Europe and Americas reporting units were €95.5 million and €86.5 million, respectively, and the carrying value of our indefinite-lived intangible assets was €89.5 million as of December 31, 2022. See "Note 8 - Goodwill and intangible assets, net" in the notes to our annual consolidated financial statements included in this annual report for further details.
Income taxes
We record income taxes under the liability method. Deferred tax assets and liabilities reflect our estimation of the future tax consequences of temporary differences between the carrying amounts of assets and liabilities for book and tax purposes. We determine deferred income taxes based on the differences in accounting methods and timing between financial statement and income tax reporting. Accordingly, we determine the deferred tax asset or liability for each temporary difference based on the enacted tax rates expected to be in effect when we realize the underlying items of income and expense.
We consider many factors when assessing the likelihood of future realization of our deferred tax assets, including our recent earnings experience by jurisdiction, expectations of future taxable income, and the carryforward periods available to us for tax reporting purposes, as well as other relevant factors. We may establish a valuation allowance to reduce deferred tax assets to the amount we believe is more likely than not to be realized. Due to inherent complexities arising from the nature of our businesses, future changes in income tax law or variances between our actual and anticipated results of operations, we make certain judgments and estimates. Therefore, actual income taxes could materially vary from these estimates.
We account for uncertain tax positions based on a two-step process of evaluating recognition and measurement criteria. The first step assesses whether the tax position is more likely than not to be sustained upon examination by the tax authority, including resolution of any appeals or litigation, based on the technical merits of the position. If the tax position meets the more likely than not criteria, the portion of the tax benefit greater than 50% likely to be realized upon settlement with the tax authority is recognized in the financial statements. Interest related to uncertain tax positions are classified in the financial statements as a component of income tax expense. The ultimate resolution of these tax positions may be greater or less than the liabilities recorded.
Share-based compensation
Our share-based compensation relates to employee stock awards granted in connection with the trivago N.V. 2016 Incentive Plan. Employee stock options primarily consist of service based awards. We measure the fair value of share options at the grant date using the Black-Scholes option pricing model. The model incorporates various assumptions including expected volatility of equity, expected term and risk-free interest rate. We amortize the fair value over the vesting term on a straight-line basis. If any of the
60




assumptions used in the model changes significantly for future grant valuations, share-based compensation expense may differ materially in the future from that recorded in the current period.

F. Tabular disclosure of contractual obligations
The following table summarizes our contractual obligations as of December 31, 2022:
Payments due by period
(in millions)TotalShort-termLong-term
Operating leases, including imputed interest (1)(2)

Purchase obligations(3)
48.5 22.4 26.1 
Total (4)
€106.0€28.4€77.6
(1) Operating lease obligations include leases for office space and office equipment. Certain leases contain renewal options. Lease obligations expire at various dates with the latest maturity in 2038. Refer to "Note 2 - Significant accounting policies" in the audited consolidated financial statements included in this annual report for detailed discussion on our accounting for operating leases. The lease obligations have not been reduced by minimum sublease rental income due in the future under non-cancelable sublease agreements which is expected to be immaterial for the future period.
(2) Currently recognized on our balance sheet as of December 31, 2022 is an asset retirement obligation of €0.1 million for the cost to decommission office space. We have certain operating lease agreements that require us to decommission physical space for which we have not yet recorded an asset retirement obligation. Due to the uncertainty of specific decommissioning obligations, timing and related costs, we cannot reasonably estimate an asset retirement obligation for these properties and we have not recorded a liability at this time for such properties.
(3) Our purchase obligations represent the minimum obligations we have under agreements with certain of our vendors and marketing partners. These minimum obligations are less than our projected use for those periods. Payments may be more than the minimum obligations based on actual use.
(4) Excludes €9.2 million of net unrecognized tax benefits for which we cannot make a reasonably reliable estimate of the period of payment.

G.    Non-GAAP financial measures
We report Adjusted EBITDA as a supplemental measure to U.S. generally accepted accounting principles ("GAAP"). We define Adjusted EBITDA as net income/(loss) adjusted for:
income/(loss) from equity method investment,
expense/(benefit) for income taxes,
total other (income)/expense, net,
depreciation of property and equipment and amortization of intangible assets,
impairment of, and gains and losses on disposals of, property and equipment,
impairment of intangible assets and goodwill,
share-based compensation, and
certain other items, including restructuring, significant legal settlements and court-ordered penalties, such as the penalty imposed by the Australian Federal Court in the proceeding brought by the ACCC against us.
From time to time going forward, we may exclude from Adjusted EBITDA the impact of certain events, gains, losses or other charges (such as restructuring charges and significant legal settlements) that affect the period-to-period comparability of our operating performance.
Adjusted EBITDA is a non-GAAP financial measure. A “non-GAAP financial measure” refers to a numerical measure of a company’s historical or future financial performance, financial position, or cash flows that excludes (or includes) amounts that are included in (or excluded from) the most directly comparable measure calculated and presented in accordance with U.S. GAAP in such company’s financial statements. We present this non-GAAP financial measure because it is used by management to evaluate our operating performance, formulate business plans, and make strategic decisions on capital allocation. We also believe that this non-GAAP financial measure provides useful information to investors and others in understanding and evaluating our operating performance and consolidated results of operations in the same manner as our management, and the exclusion of certain expenses in calculating Adjusted EBITDA can provide a useful measure in comparing financial results between periods as these costs may vary independent of core business performance.
Our use of Adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results reported in accordance with U.S. GAAP, including net income/loss. Some of these limitations are:
Adjusted EBITDA does not reflect our cash expenditures or future requirements for capital expenditures or contractual commitments;
Adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs;
Adjusted EBITDA does not reflect expenses, such as restructuring and other related reorganization costs;
Although depreciation, amortization and impairments are non-cash charges, the assets being depreciated, amortized or impaired may have to be replaced in the future, and Adjusted EBITDA does not reflect cash capital expenditure requirements for such replacements or for new capital expenditure requirements; and
Other companies, including companies in our own industry, may calculate Adjusted EBITDA differently than we do, limiting its usefulness as a comparative measure.

(1) The €20.7 million presented within the certain other items line in the tabular reconciliation for the year ended December 31, 2022 is attributable to the ACCC penalty and costs imposed on us in the judgement by the Australian Federal Court in the proceeding brought by the ACCC. Due to the size and unusual nature of the expenses relating to the judgement of the Australian Federal Court and its distorting effect on the understanding of our underlying business developments, it is also excluded when calculating Adjusted EBITDA. Of the AUD 44.7 million penalty assessed by the Australian Federal Court, a portion was accrued for over multiple accounting periods prior to the change in Adjusted EBITDA definition which took place in the first quarter of 2020. As a result, a portion of the penalty net of foreign exchange was presented within Adjusted EBITDA in prior periods. See "Note 13 - Commitments and contingencies" in the notes to our audited consolidated financial statements included in this annual report for further details.

(1) Share options granted before our IPO are calculated by converting options relating to units of trivago GmbH into options relating to shares of trivago N.V. by using the following conversion method (simplified): numbers of options were multiplied by the multiplier ratio 8,510.66824 used for purposes of our IPO. In case of trivago GmbH class B options, the result was divided by 1,000. Holders of trivago GmbH class A options with a former strike price of € 1.00 additionally received a portion of trivago N.V. options as compensation for the requirement of a higher strike price for trivago N.V. options due to corporate law requirements. In case the numbers relate to the time before the completion of our IPO, they are for illustrative purposes only and calculated using the method described above, as the actual option grants and exercises took place on the trivago GmbH level. Minor deviations can occur due to rounding.
(2) Unvested options lapse when the beneficiary leaves the Company.
(3) This award vests as follows: 1/3rd vested on January 2, 2020, and an additional 1/12th will vest quarterly thereafter until the award is fully vested, subject to continued service on such vesting dates.
(4) This award vested 1/3rd on January 2, 2021, and an additional 1/12th vested quarterly thereafter until the award was fully vested, subject to continued service on such vesting dates. The awards were not exercisable until the completion of the performance period. The award contains performance conditions which determined the number of shares earned at the end of the performance period pursuant to the respective vested stock options or restricted share units. The performance condition is based upon the two-year and three month compound annual growth rate (CAGR) of trivago's share price. Potential award levels range from 50-150% of the grant depending on the achievement of a share price CAGR ranging from >10-20% over a two-year and three month period (sliding scale). The start and end stock price is based on the 30-day trailing volume-weighted average share price. The initial performance measurement period at grant was January 2, 2020 to December 31, 2022. On October 22, 2020, the performance measurement start date was subsequently modified to October 2, 2020, which resulted in a lower anchor stock price and a shorter performance period to be used in determining the CAGR at the end of the performance period. On December 31, 2022 it was determined that 50% of the options granted are still outstanding based on the CAGR at the end of the performance measurement period.
(5) This award vests as follows: 1/3rd vested on January 2, 2021, and an additional 1/12th will vest quarterly thereafter until the award is fully vested, subject to continued service on such vesting dates.

Potential award levels range from 0-200% of the grant depending on the achievement of a share price CAGR ranging from 10-20% over a three-year period (sliding scale).

2016 Omnibus incentive plan
In connection with our IPO, we established the trivago N.V. 2016 Omnibus Incentive Plan, which we refer to as the 2016 Plan, with the purpose of giving us a competitive advantage in attracting, retaining and motivating officers, employees, management board members, supervisory board members, and/or consultants by providing them incentives directly linked to shareholder value. The maximum number of Class A shares available for issuance under the 2016 Plan is 59,635,698 Class A shares, which does not include any Class B share conversions. Class A shares issuable under the 2016 Plan will be represented by ADSs for such Class A shares. The 2016 Plan was amended on March 6, 2017 to permit the delegation of certain responsibilities to the management board. The Plan was amended on August 3, 2017 to permit supervisory board members to be eligible for awards under the 2016 Plan. The 2016 Plan was amended on June 28, 2019 to permit the granting to management and supervisory board members an option to purchase Class A shares at less than fair market value of the underlying Class A shares. The 2016 Plan was also amended on July 18, 2019 to permit additional mechanics to settle transactions. On June 30, 2020, at our general meeting, our shareholders authorized an increase of the maximum number of Class A shares available for issuance under the 2016 Plan. On March 2, 2021, our supervisory board amended the 2016 Plan to reflect this increase.
The 2016 Plan is administered by a committee of at least two members of our supervisory board, which we refer to as the plan committee. The plan committee must approve all awards to directors. Our management board may approve awards to eligible recipients other than directors, subject to annual aggregate and individual limits as may be
