General 

As used herein, references to “we,” “us,” the “company,” or “trivago,” or similar terms in this Annual Report 
on Form 20-F shall mean trivago N.V. and, as the context requires, its subsidiaries. 

Our financial statements are prepared in accordance with U.S. Generally Accepted Accounting Principles, 
or U.S. GAAP. Unless otherwise specified, all monetary amounts are in euros. All references in this annual 
report to “$,” “US$,” “U.S.$,” “U.S. dollars,” “dollars” and “USD” mean U.S. dollars, and all references to “€” 
and “euros,” mean euros, unless otherwise noted. 

We have historically conducted our business through trivago GmbH, and therefore our historical financial 
statements prior to our initial public offering, or IPO, present the results of operations and financial condition 
of trivago GmbH and its controlled subsidiaries. In connection with our IPO, trivago N.V. became the holding 
company of trivago GmbH, and the historical consolidated financial statements of trivago GmbH became 
the historical consolidated financial statements of trivago N.V. On September 7, 2017, the merger of trivago 
GmbH into and with trivago N.V. became effective. Pursuant to the merger, Messrs. Schrömgens, Vinnemeier 
and Siewert (whom we collectively refer to as our Founders) exchanged all of their units of trivago GmbH 
remaining after our pre-IPO corporate reorganization for Class B shares of trivago N.V. 

The historical financial statements of trivago GmbH and its controlled subsidiaries made reference to the 
members’ equity as trivago GmbH Class A units and trivago GmbH Class B units. The equity of a GmbH is 
not  unitized  into  shares  under  German  corporate  law.  However,  pursuant  to  the  company’s  articles  of 
association, we unitized members’ equity into trivago GmbH Class A units and Class B units, with each 
trivago GmbH Class B unit having 1/1,000 of the voting rights and economic rights of a trivago GmbH Class 
A unit.

Special note regarding forward-looking statements 
This annual report contains forward-looking statements within the meaning of Section 27A of the Securities 
Act of 1933, as amended, or the Securities Act, and Section 21E of the Securities Exchange Act of 1934, 
as amended, or the Exchange Act, that are based on our management’s beliefs and assumptions and on 
information currently available to our management. All statements other than present and historical facts 
and conditions contained in this annual report, including statements regarding our future results of operations

You should refer to the section of this annual report titled “Item 3 D. Risk factors” for a discussion of important 
factors that may cause our actual results to differ materially from those expressed or implied by our forward-
looking statements. As a result of these factors, we cannot assure you that the forward-looking statements 
in this annual report will prove to be accurate. Furthermore, if our forward-looking statements prove to be 
inaccurate, the inaccuracy may be material. In light of the significant uncertainties in these forward-looking 
statements, you should not regard these statements as a representation or warranty by us or any other 
person that we will achieve our objectives and plans in any specified time frame or at all. We undertake no 
obligation to publicly update any forward-looking statements, whether as a result of new information, future 
events or otherwise, except as required by law. 

You should read this annual report and the documents that we reference in this annual report and have filed

(4)  Represents earnings per share of Class A and Class B common stock and weighted-average shares of Class A and Class B 
common stock outstanding for the period from December 16, 2016 to December 31, 2016, the period following the capitalization 
of the parent company and IPO, and for the period from January 1, 2017 to December 31, 2017 (see Note 14).

(5)  We  define  adjusted  EBITDA  as  net  loss  plus:  (1) expense  (benefit)  for  income  taxes;  (2) total  other  income  (expense),  net; 
(3) depreciation  of  property  and  equipment,  including  amortization  of  internal  use  software  and  website  development; 
(4) amortization of intangible assets; and (5) share-based compensation. 

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 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 in comparing financial results across accounting 
periods. 

    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 GAAP, including net 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; 

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

€
€
€

•  Other companies, including companies in our own industry, may calculate adjusted EBITDA differently than we do, limiting its 

usefulness as a comparative measure. 

We have provided a reconciliation below of adjusted EBITDA to net loss, the most directly comparable GAAP financial measure.

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 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 report and our other SEC filings. See “Special note regarding 
forward-looking statements” above.

Risks related to our industry and business

We derive a large portion of our revenue from a relatively small number of advertisers. A reduction 
in spending or any change in bidding strategy by one or more 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. Although we aim to improve advertiser diversification and competition 
on our marketplace in the long term, we continue to generate the great majority of our revenue from our 
largest online travel agency, or OTA, advertisers. For the years ended December 31, 2015, 2016 and 2017, 
we generated 27%, 43% and 44% of our total revenue, respectively, from Booking Holdings (formerly The 
Priceline Group), including its affiliated brands Booking.com and Agoda. Brands affiliated with our majority 
shareholder, Expedia, Inc., or Expedia, accounted for 39%, 36% and 36% of our total revenue for the years 
ended December 31, 2015, 2016 and 2017, respectively.

Our ability to grow revenue from our existing advertisers, whether large or not, is dependent to a significant 
extent on our ability to maintain and diversify our relationships with them. Advertisers are likely to reduce 
their advertising on our platform or cease it altogether if their advertising spend does not generate referrals, 
customers, bookings or revenue and profit for them on a basis they deem to be cost-effective. Advertisers 
may reduce or cease their advertising on our platforms for reasons not related to the value we can deliver 
to them, such as a weakening of their own financial or business conditions or external economic effects. 
The loss of any of our major advertisers, including Expedia, Booking Holdings or their affiliated brands, on 
some or all of our platforms, or a reduction in the amount they spend, could result in significant decreases 
in our revenue, as well as an increase in credit losses, and could have a material adverse effect on our 
business, results of operations, financial condition and prospects.

Even if we are able to 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 can permit 
them, depending on marketplace dynamics, to adjust their CPC bids and obtain the same or increased levels 
of referrals, customers, bookings or revenues and profit at lower cost. This can occur if one or more advertisers 
change their return-on-investment targets on our marketplace, including on a country or regional level, and 
such advertisers have sufficient market share to influence our aggregate CPC levels. In the second half of 
2017, advertisers representing a significant portion of our revenues increased their testing activities on our 
marketplace and changed their bidding strategies, significantly impacting their CPC bids on our marketplace 
in  various  geographic  markets.  Some  advertisers  have  also  deactivated  some  of  their  inventory,  most 
frequently inventory that they alone advertised or that was inactive, and have withdrawn from our marketplace 
for periods of time in certain geographic markets. We do not have reliable insights as to the advertising or 
CPC levels or other strategic goals they hope to achieve through their testing and bidding strategies, and 
are unable to predict with any degree of certainty the likely effects that potential changes in testing and 
bidding strategies in the future could have on our business, results of operations, financial condition and 
prospects of their actions.

Our advertisers may also test how changes in their bidding strategies on our marketplace can affect their 
strategies on other marketing channels, particularly in auctions for search engine keywords on Google. We 

9

regularly  compete  with  our  advertisers  on  these  marketing  channels  and  adjust  our  spending  on  those 
channels based on trends we see in our results. If changes in large advertisers’ strategies on our marketplace 
cause us to spend significantly less on these marketing channels, and we generate fewer qualified referrals 
as a result, our revenue and results of operations could be adversely affected. In addition, such advertisers 
could  also  experience  improvements  in  their  competitiveness  on  such  channels,  providing  them  with 
additional financial benefits from pursuing such a strategy.

If we are unable to increase the diversity of our advertiser base, we will continue to be subject to the risks 
that advertiser concentration can lead to the adverse effects described above. The manifestation of any of 
these  risks  is  likely  to  have  a  material  adverse  effect  on  our  business,  financial  position  and  results  of 
operations.

We are subject to a number of factors that contribute to significant quarter-to-quarter volatility in 
our financial condition and results of operations. These factors have impacted and may continue to 
negatively impact our ability to meet the financial guidance that we communicate to the market.

Our financial condition and results of operations have varied and may continue to vary considerably from 
quarter to quarter. This was reflected in the rapid slowdown in revenue growth that we experienced in the 
second half of 2017. The magnitude of the fluctuations in our financial results can be influenced, as mentioned 
above, by the fact that a large portion of our revenue is concentrated in referral revenue generated from 
brands  affiliated  with  Expedia  and  Booking  Holdings.  This  concentration  means  that  changes  in  these 
advertisers' strategies on our marketplace can have material impacts on our referral revenue in a given 
financial period. Changes in referral revenue resulting from dynamics on our marketplace, whether or not 
relating to our largest advertisers, can occur with little or no notice to us, and can result in our not having 
enough time to pull back our advertising spend, particularly on television, quickly enough to respond to the 
speed of the change in revenue levels. As we spend the great majority of our revenues on advertising, such 
a failure to pull back advertising spend quickly enough can have a rapid adverse effect on our results of 
operations. 

The difficulty of predicting advertiser behavior and outcomes on our marketplace make it challenging for us 
to forecast advertiser demand, especially since our advertisers can and often do change their CPC bid levels 
with little or no notice to us. In addition, nearly all of our agreements with OTAs, hotel chains and independent 
hotels may be terminated at will or upon three to seven days’ prior notice by either party. As a result, the 
financial guidance that we provide is subject to significant uncertainty, especially when the factors above 
are considered together with other trends, such as changing foreign exchange rates, user demand for travel 
services, regional and global economic conditions and other external factors that may impact our users’ 
discretionary spending. These fluctuations and any resulting inability to meet financial guidance may have 
a material adverse effect on our business, results of operations, financial condition and prospects.

As  our  business  matures,  we  may  not  be  able  to  grow  our  revenue  in  future  periods  at  rates 
comparable to those in the past. 

Our revenue in 2017 grew by 37% compared to 2016, which represented a significant slowdown compared 
to revenue growth of 53% in 2016 versus 2015. Although we have communicated that we expect to return 
to a positive trajectory in terms of our rate of revenue growth in the second half of 2018, we may not be able 
to increase our revenue in future periods at rates comparable  to those in the past, or our revenue may 
decline. This may occur for any number of reasons, particularly as our business matures, and may reflect: 

• 

• 

• 

the possibility that our advertisers prioritize profitability over traffic growth; 

declines in the emphasis that our advertisers wish to place on hotel metasearch as an advertising channel, 
particularly as we increasingly compete with them for traffic on other advertising channels, including on 
television and in auctions for search engine keywords (including bidding for trivago-related keywords); 

possible  reductions  in  the  marginal  returns  from  our  advertising  spend  reflecting  changes  in  the 
effectiveness of our advertising over time, and our brand awareness in light of the strategies of our 
competitors as they may choose to increase their advertising spend; 

10

• 

• 

• 

a  slowdown  or  reduction  in  our  ability  to  attract  and  retain  users  in  an  increasingly  competitive 
environment; 

the emergence of alternative business models and new competitors; and

slowing growth of the overall online hotel search market, due for example to market saturation in more 
mature markets.

In the future, as our growth rate slows or declines, we expect the variability, cyclicality and seasonality in 
our business to become more pronounced, or in any event more apparent, as our high rates of growth in 
recent years tended to mask these characteristics. This could result in greater fluctuations of our revenue, 
cash flows, results of operations and other key performance measures from period to period and may affect 
the price of our ADSs and increase volatility in that price. 

While the size of our user base continues to increase, we anticipate that the growth rate of our user base 
may decline as our business matures. We may also lose users for other reasons, such as a failure to deliver 
satisfactory search results, transaction experiences or high-quality services. In addition, even if our user 
base continues to grow, our revenue may not grow at the same rate or at all. If our growth rates continue to 
decline or if our revenue declines, as was already the case in Developed Europe in the fourth quarter of 
2017, our results of operation, business and prospects may be adversely affected.

We are dependent on general economic conditions, and declines in travel or discretionary spending 
generally could reduce the demand for our services. 

Our results of operations and financial prospects are significantly dependent upon users of our services and 
the prosperity and solvency of the OTAs, hotel chains and independent hotels that have relationships with 
us. Travel, including hotel room reservations, is dependent on personal and business discretionary spending 
levels.  Travel  services  tend  to  decline,  along  with  the  advertising  budgets  spent  by  hotels  and  other 
accommodation aggregators, during general economic downturns and recessions. Events and developments 
that cause deteriorations in economic conditions on a national, regional or global level, or are perceived as 
likely to lead to such deteriorations, can quickly affect our business. In particular, our financial results may 
be adversely impacted by economic uncertainty arising from negotiations between the European Union and 
the  United  Kingdom  relating  to  the  United  Kingdom’s  anticipated  withdrawal  from  the  European  Union. 
Conditions that reduce disposable income or consumer confidence, such as an increase in interest rates 
(which, among other things, could cause consumers to incur higher monthly expenses under mortgages), 
unemployment rates, direct or indirect taxes, fuel prices or other costs of living, may lead users to reduce 
or stop their spending on travel or to opt for lower-cost products and services, and these conditions may be 
particularly prevalent during periods of recession, economic downturn or market volatility and disruption. 
International  travel  may  also  be  affected  by  changes  in  exchange  rates  among  significant  origin  and 
destination countries.

Any significant decline in travel, consumer discretionary spending or the occurrence of any of the foregoing 
conditions may reduce demand for our services. They can also cause advertisers to become insolvent or 
fail to pay us for services we have already provided. The occurrence of any of the above could have a material 
adverse effect on our business, results of operations, financial condition and prospects. 

Our ability to maintain our current financial performance, brand awareness and growth is dependent 
on  the  effectiveness  of  our  advertising  expenditures.  Increased  competition,  or  inadequate  or 
ineffective  innovation  in  this  area  could  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. Many of our competitors have more resources than we do and can spend more on advertising 
their brands and services. As a result, we are required to spend considerable amounts of money and other 
resources to preserve and increase our brand awareness and grow our business. Competition for top-of-
mind awareness and brand preference is intense among online hotel search services, globally and in key 

11

geographies. If we are unable to effectively preserve and increase our brand awareness, we may be unable 
to successfully maintain or enhance the strength of our brand. 

In recent years, we have engaged successful broad-reach TV marketing campaigns. We expect to continue 
to invest in TV 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. In addition, our advertising efforts may become less cost 
effective or less efficient than they have been historically. 

In order to maintain or increase the effectiveness of our TV advertisements, we may need to develop new 
creative concepts in our advertisements, and these advertisements may not be as effective in terms of return 
on advertising spend as those we have used in the past. 

In addition, our competitors may increase their spending on advertisement campaigns, which could cause 
the  marginal  returns  on  our  advertisements  to  decline.  This  may  occur  even  if  we  make  substantial 
investments  in  innovation  in  technology  and  concepts  in  this  area.  Increased  advertising  spend  by  our 
competitors 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 effective marketing and advertising channels for reasons of cost. 

TV advertising accounts for a large percentage of our advertising expense, and often has higher costs than 
other  channels.  Our  marginal  returns  from TV  advertising  may  also  be  negatively  affected  over  time  by 
declining viewership in certain age groups and changes in viewing patterns that reduce viewer exposure to 
advertising.  If  TV  advertising  becomes  less  effective  or  if  we  experience  diminishing  returns  from  TV 
advertising overall or in key markets, we may instead invest in other, more expensive channels, which may 
not be as successful. In order to maintain our brand awareness, we may also need to invest in new advertising 
formats, such as online video, with which we have less experience. 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.

In addition, we intend to continue expanding our operations globally, including in countries where we have 
limited operating experience, that may have different competitive conditions and where users may have 
different travel preferences. Users in other countries may not be familiar with our brand, or may be less 
familiar with our brand than that of a competitor, and we may need to build brand awareness in such countries 
through  greater  investments  in  advertising  and  promotional  activities.  To  the  extent  we  have  limited 
experience in these countries, we may be slow or fail to find the most effective and cost-efficient advertising 
channels there.

We are currently taking steps to increase advertiser diversity on our marketplace. If these measures 
are unsuccessful and we are unable to integrate additional inventory to our platform, or successfully 
to monetize that inventory, our financial performance could be materially adversely affected. 

We have recently taken steps to increase advertiser diversity on our marketplace, including increasing the 
representation of individual hotels into our inventory, making investments in our advertisement relations team 
and integrating the vacation rental inventory of HomeAway, Inc., or HomeAway, onto our hotel search platform, 
with the aim of integrating additional inventory of alternative accommodation, such as vacation rentals, going 
forward. Increasing the representation of individual hotels on our platform requires large, skilled, multi-lingual 
sales teams that, even after the investments we expect to make, will still be substantially smaller and less 
experienced than the advertising teams of many of our competitors. In the case of vacation rentals, we face 
challenges in integrating these properties into our platform since those properties have attributes substantially 
different from hotel rooms, our traditional area of focus. In addition, the online vacation rental market is rapidly 
evolving, and if we fail to predict the manner in which that market develops or if large vacation rental providers 
are able to acquire a larger share of the alternative accommodation market at our expense, our financial 
performance may be harmed. 

12

If  our  efforts  to  integrate  additional  inventory  and  diversify  our  marketplace  are  unsuccessful  or  if  our 
competitors can provide more attractive advertising terms to potential advertisers, we may be unable to 
provide as broad a set of search results and as detailed pricing information to our users as our competitors 
are able to provide, which may have a material adverse effect on our business, results of operations, financial 
condition and prospects.

Increasing competition and consolidation in our industry could result in a decrease in the amount 
and types of hotel information we display, the value of our services to users and a loss of users, 
which would adversely affect our business, financial performance and prospects.

We  operate  in  the  highly  and  increasingly  competitive  travel  industry.  Many  of  our  current  and  potential 
competitors, including hotels themselves (both hotel chains and independent hotels), global metasearch and 
review websites, such as Kayak, TripAdvisor and Google Hotel Ads, locally focused metasearch engines 
such as Qunar, OTAs, such as Booking.com, Ctrip and Brand Expedia, alternative accommodation websites, 
such as Airbnb and HomeAway, and other hotel websites, have been in existence longer, may have larger 
user bases, may have a 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.  Metasearch  websites  are  also  expanding  globally,  are  becoming 
increasingly  competitive,  and  are  in  some  cases  adopting  strategies  and  developing  technologies  and 
websites that are very similar to ours. 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. 
If fewer advertisers choose to advertise on our website, we will have less information available to display, 
which makes our services less valuable to users.

In addition, many of these competitors may be able to devote significantly greater resources to marketing 
and promotional campaigns; attracting and retaining key employees; securing participation of hotels and 
access to hotel information, including proprietary or exclusive content; website and systems development; 
research and development; and enhancing the speed at which their services return user search results. Our 
competitors may also be able to adjust their marketing spend more quickly than we can. Many of these 
competitors may also offer user incentives, such as loyalty points or priority access to services, which may 
not be available if users book through third-party sites or services. In the recent past, certain hotel chains 
have launched advertising campaigns expressly designed to drive consumer traffic directly to their websites. 
Furthermore, certain alternative accommodation websites have added other travel services, such as tours, 
activities, hotel and flight bookings, any of which could further extend their reach into the travel market.

In  addition,  consolidation  among  advertisers,  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, which could cause our services to become less valuable and popular for users 
and could result in advertisers bidding less for offers or even terminating their relationships with us. 

As  a  result,  competition  and  consolidation,  individually  or  in  the  aggregate,  could  result  in  higher  traffic 
acquisition costs, reduced operating margins, loss of market share, reduced user traffic to our websites and 
reduced advertising by OTAs and hotels on our websites. If our large customers become less competitive 
with each other, merge with each other, focus more on profit than on traffic volume, or are able to reduce 
CPCs, this would have an adverse impact on our CPCs which, in turn, may have a material adverse effect 
on  our  business,  results  of  operations,  financial  condition  and  prospects.  In  addition,  competition  and 
consolidation among our advertisers may cause some of them to have financial difficulties, default on or 
materially delay their obligations to pay us for services we have already provided or become insolvent. As 
a result, we may not be able to compete successfully against current and future competitors, and competition 
and/or  consolidation  among  advertisers  may  have  a  material  adverse  effect  on  our  business,  results  of 
operations, financial condition and prospects. 

13

We have chosen to focus exclusively on providing search services for hotels and other types of 
accommodation. If users expect to be able to book other services when they book accommodation, 
they may choose to utilize the websites of our competitors rather than ours, which would negatively 
impact our financial condition and results of operations.

We are focused exclusively on helping users find their ideal hotel room, with an increasing focus on other 
types of accommodation. Because we believe this focus will help us develop a platform that displays hotels 
that match individual users’ ideal hotel characteristics, we have decided that our search engine should not 
cover services that are outside our core area of focus. As a result, users cannot use our platform to book 
air travel, rental cars, tours, cruises and other services with our advertisers, while they can book or otherwise 
obtain information about these services on the websites of 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  our  users  demand  to  see  more 
comprehensive offers akin to those of our competitors, we may not realize the anticipated benefits of this 
strategy, which could negatively impact our competitiveness, financial condition and results of operations.

If  we  do  not  continue  to  innovate  and  provide  tools  and  services  that  are  useful  to  users  and 
advertisers, we may not remain competitive, and our revenue and results of operations could suffer. 

Our success depends on continued innovation to provide features and services that make our websites and 
apps  useful  for  users.  Our  ability  to  attract  users  to  our  services  depends  in  large  part  on  providing  a 
comprehensive set of search results and a broad range of offers across price ranges. To do so, we maintain 
relationships with OTAs, hotel chains and independent hotels to include their data in our search results. 
Although we maintain searchable databases of hotels in the world, we do not have relationships with some 
significant potential advertisers, including some major hotel chains and many independent hotels and smaller 
chains. The loss of existing relationships with advertisers, our inability to continue to add new ones, or the 
decision  by  one  or  more  advertisers  to  deactivate  part  or  all  of  their  of  their  inventories  in  on  or  more 
geographical regions, may reduce the comprehensiveness of our search results, which could reduce user 
confidence in the search results we provide, making us less popular.

In  addition,  our  competitors  are  constantly  developing  innovations  in  online  hotel-related  services  and 
features. As a result, we must continue to invest significant resources in research and development in order 
to continuously improve the speed, accuracy and comprehensiveness of our services. We have invested, 
and in the future may invest, in new business strategies and services. These strategies and services may 
not succeed, and, even if successful, our revenue may not increase. In addition, we may fail to adopt and 
adapt to new technology, especially as Internet search, including through Google and Amazon, potentially 
moves from a text to voice interface over the coming years. If we are unable to continue offering innovative 
services,  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. 

 One of our product features depends in part on our relationship with third parties to provide us with 
consumer reviews. 

Third parties provide us with consumer reviews that we provide users along with our proprietary rating score. 
If these 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 users’ perception 
of the value of our product and our reputation. 

14

The measures we are implementing that are designed to maximize the lifetime value of the user may 
not generate the long-term financial benefits that we anticipate.

We are implementing initiatives that are designed to focus less on revenue generated in each user session 
and more on the end-to-end booking value of our users. These initiatives are intended to help us increase 
booking conversion rates, revenue per qualified referral and, ultimately, we believe, our financial performance 
over the long term. However, these changes may have an adverse effect on revenue and/or profitability in 
the short or medium term. Some of these changes include:

•  Measures aimed at optimizing our platforms and product, with the intention of increasing user retention 
and booking conversion, while reducing the number of click-outs required to ultimately make a booking;

•  Our relevance assessment, which reflects our assessment of the quality of users' experience after clicking 
out to an advertiser from our website and functions as an adjustment to advertisers’ CPC bids in our 
marketplace auction process; and 

•  Our attribution model, which is our model for allocating our performance marketing spend and which we 
continuously modify to reflect changes in how we determine whether revenue originated from a given 
marketing channel (or how revenue is “attributed” to that channel in our internal metrics) and that informs 
decisions we make about how much we spend on different performance marketing channels. The new 
attribution focuses on whether a user who comes to us from a performance marketing channel books a 
hotel. In the third quarter, we completed the roll-out of this new attribution model in our “Display, Email 
and Affiliate Advertising,” or “DEA,” channel. In the fourth quarter of 2017, we continued to implement 
this new attribution model in our "Search Engine Marketing," or "SEM," channel. 

Although we aim for these measures to have a long-term positive effect on our profitability by focusing on 
traffic quality instead of volume, they may not produce the long-term financial benefits that we expect. We 
rely on assumptions, estimates and test data to determine whether these changes to our marketplace and 
advertising spend are effective, particularly in terms of booking conversion. In particular, we assume that 
our advertisers will ultimately be willing to pay more for referrals that are more likely, in our view, to lead to 
a completed booking. However, this assumes that our definition of value matches that of our advertisers, 
who may instead perceive value in referrals that do not result in an immediate hotel booking but have the 
potential to deliver repeat users of their websites in the future. If our advertisers do not perceive added value 
for them from enhancements we make, they may be unwilling to pay us more after we have introduced these 
enhancements, in which case our user growth, business and our results of operations could be negatively 
impacted. 

In addition, while we expect these initiatives may lead to short-to medium-term reductions in our revenue 
growth and profitability, the extent of these effects is difficult to predict, and the initiatives could cause revenues 
to grow more slowly than we anticipate or lead to revenue declines, and could lead to losses. They may also 
lead to increased volatility in our results. As an example, our revenue levels may be negatively impacted or 
may become more volatile as our advertisers take measures to respond to the automated version of the 
relevance assessment that we introduced in the fourth quarter of 2017. In addition, we expect higher volatility 
in our results and potentially a slowdown in qualified referral growth in the near term as a result of the roll-
out of the attribution model to areas other than DEA. 

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 ultimately convert 
any  improvements  into  increased  revenue.  While  the  internal  data  we  use  to  judge  the  effectiveness  of 
changes to our platform is 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 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 

15

transaction with them. Our ability to track user behavior is also subject to considerable limitations, for example, 
relating to our ability to use browser extensions and cookies to analyze behavior over time, and to difficulties 
pertaining to users who use multiple devices to conduct their search for accommodation. 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.  Furthermore,  our  or  our  advertisers’ 
methodologies for tracking this information may change over time. If the internal tools we use to judge the 
effectiveness of changes to our platform produce or are based on information with inaccuracies, 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 financial condition and results of operations. 

We rely on search engines, which may change their business models or search engine algorithms 
in ways that could have a negative impact on our business, financial performance and prospects. 

We use Baidu, Bing, Google, Yahoo! and other Internet search engines to generate 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. 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 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. 

To the extent that Google or other leading search or metasearch engines that have a significant presence 
in  our  key  markets,  disintermediate  OTAs  or  travel  content  providers,  whether  by  offering  their  own 
comprehensive travel planning or shopping capabilities, or by referring leads to suppliers, other favored 
partners or themselves directly, there could be a material adverse impact on our business and financial 
performance. In particular, Google appears to continue to direct an increasing amount of traffic to its own 
hotel search platform (which it refers to as “Hotel Ads”) at the expense of traditional keyword auctions. We 
purchase hotel-related keywords on Google to obtain a significant amount of traffic, but do not currently use 
Hotel Ads as a marketing channel (although we have conducted some testing). If we were to do so, Hotel 
Ads may present a challenge since we would have significantly less flexibility to direct traffic to our website 
using that platform. In particular, our placement in Hotel Ads’ results would be dependent on factors used 
by its algorithm to rank and display our offers, resulting in dynamics significantly different from Search Engine 
Marketing in the form that we are currently familiar with. In addition, our major advertisers might not be 
amenable to our using their inventory to compete with them on Hotel Ads, which would present a further 
difficulty if Google continues to direct traffic in this manner. 

In  addition,  a  significant  amount  of  traffic  is  directed  to  our  websites  through  our  participation  in  DEA 
campaigns on search engines, advertising networks, affiliate websites and social networking sites. Pricing 
and  operating  dynamics  for  these  traffic  sources  can  experience  rapid  change,  both  technically  and 
competitively. Any  of  these  providers  could  also,  for  competitive  or  other  purposes,  alter  their  search 
algorithms or results, causing our websites to place lower in search results, which may reduce our user traffic 
and  may  have  a  material  adverse  effect  on  our  business,  results  of  operations,  financial  condition  and 
prospects.

A  failure  to  comply  with  current  laws,  rules  and  regulations  or  changes  to  such  laws,  rules  and 
regulations and other legal uncertainties may adversely affect our business, financial performance, 
results of operations or business growth.

Our  business  and  financial  performance  could  be  adversely  affected  by  unfavorable  changes  in  or 
interpretations of existing laws, rules and regulations or the promulgation of new laws, rules and regulations 
applicable to us and our businesses, including those relating to hotels, the Internet and online commerce, 
Internet  advertising  and  price  display,  consumer  protection,  anti-corruption,  anti-trust  and  competition, 
economic and trade sanctions, tax, banking, data security and privacy. As a result, regulatory authorities or 
courts could prevent or temporarily suspend us from carrying on some or all of our activities or otherwise 
penalize us (including financial penalties and adverse findings) if our practices were found not to comply 
with applicable legal, regulatory or licensing requirements or any binding interpretation of such requirements. 
Unfavorable changes or interpretations, and changes we might be required to make to our practices as a 
result, could decrease demand for our services, limit marketing methods and capabilities, affect our margins, 
increase costs or subject us to additional liabilities.

Regulators have recently increased their focus on the consumer facing business practices of companies 
active in the Internet search sector, in particular with respect to the providers of online travel search and 
booking services. A number of regulators in various countries have made public statements that they are 
investigating the sector generally and individual companies concerning their marketing and selling practices. 
For example, on October 27, 2017 the U.K. Competition and Markets Authority, or CMA, announced the 
launch of an investigation into online hotel booking sites, with focal points on how hotels are ranked in search 
results, whether claims on the sites create a false impression of rate or room availability or rush customers 
into  making  a  booking  decision,  whether  the  discount  claims  made  on  sites  offer  a  fair  comparison  for 
customers and the extent to which sites include all costs in the price they first show customers, and the CMA 
has written to companies across the whole sector in the United Kingdom, including us, requiring information 
to  understand  more  about  their  practices.  On  October  24,  2017,  the  German  Federal  Cartel  Office 
(Bundeskartellamt) announced a sector inquiry focused on the consumer facing practices of online price 
comparison  websites  active  in  the  travel,  insurance,  financial  services,  telecommunications  and  energy 
sectors in Germany, covering topics such as rankings, financing, corporate links, reviews, availability and 
relevant market coverage to assess whether consumer law provisions may have been violated. We have 
also been contacted by the Australian Competition and Consumer Commission, or ACCC. The ACCC has 
requested information and documents from us relating to our advertisements in Australia concerning the 
hotel prices available on our Australian site and our strike-through pricing practice on that site, which is the 
display adjacent to the price quote in the top position in our search results of a higher price that is crossed 
out.  Should  changes  in  our  sector  brought  about  by  this  regulatory  attention  reduce  the  attractiveness, 
competitiveness or functionality of our platform and the services we offer, or should our reputation or that of 
our  sector  suffer,  or  should  we  have  to  pay  substantial  amounts  in  respect  or  as  a  result  of  any  such 
proceedings,  our  results  of  operations,  financial  condition  and  prospects  could  be  materially  adversely 
affected.

In addition, there 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. Furthermore, the growth 
and development of online commerce may prompt calls for additional or more complex consumer protection 
laws and higher levels of regulatory review and enforcement activities, which may impose additional burdens, 
costs or limitations on online businesses generally.

Likewise, the SEC, U.S. Department of Justice and U.S. Office of Foreign Assets Control, or OFAC, as well 
as other foreign regulatory authorities, have continued to increase the enforcement of economic and trade 
regulations and anti-corruption laws, across industries. U.S. trade sanctions restrict transactions involving 
designated foreign countries and territories, including the Crimea region of Ukraine, Cuba, Iran, North Korea, 
Sudan and Syria, as well as certain specifically targeted individuals and entities. We believe that our activities 
comply with applicable OFAC trade regulations and anti-corruption regulations, including the U.S. Foreign 

17

Corrupt Practices Act and the UK Bribery Act. As regulations are amended and the interpretation of those 
regulations evolves, we cannot guarantee that our programs and policies will be deemed compliant by all 
applicable regulatory authorities. In the event that our controls should fail or are found to be not in compliance 
for  other  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.

The promulgation of new laws, rules and regulations, or the new interpretation of existing laws, rules and 
regulations, in each case that restrict or otherwise unfavorably impact the ability or manner in which we 
provide our services could require us to change certain aspects of our business, operations and commercial 
relationships to ensure compliance, which could decrease demand for services, reduce revenue, increase 
costs or subject the company to additional liabilities.

Litigation,  including  the  purported  securities  class  actions  currently  pending  against  us,  could 
distract management, increase our expenses or subject us to material monetary damages and other 
remedies.

trivago N.V. and certain of its management board members are the subject of two purported class actions, 
filed in the United States District Court for the Southern District of New York following the announcement by 
the U.K. Competition and Markets Authority of the investigation described above, asserting claims under the 
Exchange Act and the Securities Act on behalf of persons who purchased or otherwise acquired trivago’s 
American Depositary Receipts pursuant and/or traceable to the registration statement and prospectus issued 
in connection with our IPO on or about December 16, 2016 and/or on the open market between December 
16, 2016 and October 27, 2017. One of the complaints also named underwriters of our IPO as defendants. 
On January 22, 2018, the court appointed the lead plaintiff and lead counsel in the actions, and they now 
have the opportunity to file an amended complaint. While it is too early for us to form any view on the likely 
outcomes of these actions, their outcomes could have a material adverse effect on our business, financial 
condition or results of operations.

We could also become involved from time to time in various other legal proceedings, including, but not limited 
to, actions relating to breach of contract, consumer protection matters and intellectual property infringement 
that might necessitate changes to our business or operations. Regardless of whether the securities litigation 
described above or any other claims against us have merit, or whether we are ultimately held liable or subject 
to payment of damages, claims may be expensive to defend and may divert management’s time away from 
our operations. If any legal proceedings were to result in an unfavorable outcome, it could have a material 
adverse effect on our business, financial position and results of operations. Any adverse publicity resulting 
from actual or potential litigation may also materially and adversely affect our reputation, which in turn could 
adversely affect our results.

Companies  in  the  Internet,  technology  and  media  industries  are  frequently  subject  to  allegations  of 
infringement or other violations of intellectual property rights. We are currently subject to several claims and 
may be subject to future claims relating to intellectual property rights. As we grow our business and expand 
our operations we may be subject to intellectual property claims by third parties. We intend to vigorously 
defend our intellectual property rights and our freedom to operate our business; however, regardless of the 
merits of the claims, intellectual property claims are often time consuming and extremely expensive to litigate 
or settle and are likely to continue to divert managerial attention and resources from our business objectives. 
Successful infringement claims against us could result in significant monetary liability or prevent us from 
operating our business or portions of our business. Resolution of claims may require us to obtain licenses 
to use intellectual property rights belonging to third parties, which may be expensive to procure, or we may 
be required to cease using intellectual property of third parties altogether. Many of our agreements with 
hotels, OTAs and other partners require us to indemnify these entities against third-party intellectual property 
infringement claims, which would increase our defense costs and may require that we pay damages if there 
were an adverse ruling in any such claims. Any of these events may have a material adverse effect on our 
business, results of operations, financial condition and prospects.

18

We process, store and use personal data which exposes us to risks of internal and external security 
breaches  and  could  give  rise  to  liabilities,  including  as  a  result  of  governmental  regulation  and 
differing legal obligations applicable to data protection and privacy rights.

We may acquire personally identifiable information or confidential information from users of our websites 
and apps. Breaches or intrusions to our system, whether resulting from internal or external sources, could 
significantly harm our business. It is possible that advances in computer circumvention capabilities, new 
discoveries or other developments, including our own acts or omissions, could result in a compromise or 
breach of personally identifiable information and/or confidential user information. 

We cannot guarantee that our existing security measures will prevent all security breaches, intrusions or 
attacks. A party, whether internal or external, that is able to circumvent our security systems could steal user 
information or proprietary information or cause significant disruptions to our operations. In the past, we have 
experienced  “denial-of-service”  type  attacks  on  our  system  that  have  made  portions  of  our  website 
unavailable for periods of time. We may need to expend significant resources to protect against security 
breaches, intrusions, attacks or other threats or to address problems caused by breaches. Any actions that 
impact the availability of our website and apps could cause a loss of substantial business volume during the 
occurrence of any such incident and could result in reputational harm and impact negatively our ability to 
attract new customers and/or retain existing ones. The risk of security breaches, intrusions and other attacks 
is likely to increase as we expand the number of markets in which we operate and as the tools and techniques 
used in these types of attacks become more advanced. The new European data protection laws (described 
in detail below), introduce mandatory breach reporting to regulators and individuals across Europe. Security 
breaches could result in negative publicity, damage to our reputation, expose us to risk of loss or litigation 
and possible liability and subject us to regulatory penalties and sanctions as well as civil litigation. Security 
breaches could also cause users and potential users to lose confidence in our security, which would have 
a negative effect on the value of our brand. 

We also face risks associated with security breaches affecting third parties conducting business over the 
Internet.  Users  generally  are  increasingly  concerned  with  security  and  privacy  on  the  Internet,  and  any 
publicized security problems impacting other companies could inhibit the growth of our business. Additionally, 
security  breaches  at  third  parties  upon  which  we  rely,  such  as  hotels,  could  result  in  negative  publicity, 
damage  to  our  reputation,  expose  us  to  risk  of  loss  or  litigation  and  possible  liability  and  subject  us  to 
regulatory or criminal penalties and sanctions as well as civil litigation. We currently provide users with the 
functionality to book directly with certain hotels, by completing a form on our website which enables users’ 
details to be transferred directly to the hotel’s booking forms. In connection with facilitating these transactions, 
we  receive  and  store  certain  personally  identifiable  information,  including  credit  card  information.  This 
information is increasingly subject to legislation and regulations in numerous jurisdictions around the world, 
including throughout the member states of the European Union as a result of European Commission Directive 
95/46/EC  and  implementing  legislation  in  effect  in  member  states  of  the  European  Union,  which  will  be 
replaced from May 25, 2018 by the EU’s General Data Protection Regulation 2016/679 (GDPR). In particular, 
EU laws regulate transfers of EU personal data to third countries, such as the United States, that have not 
been found to provide adequate protection to such personal data. A considerable number of our service 
providers  and  hotels  operate  in  such  jurisdictions.  There  are  recent  regulatory  concerns  about  certain 
measures  that  can  be  used  to  validate  such  data  export,  as  well  as  litigation  challenging  some  of  the 
mechanisms for adequate data transfer (i.e., the standard contractual clauses). We could be impacted by 
changes in law as a result of the current challenges to these mechanisms by regulators and in the European 
courts which may lead to governmental enforcement actions, litigation, fines and penalties or adverse publicity 
which could have an adverse effect on our reputation and business. 

Government regulation of privacy and data security is typically intended to protect the privacy of personally 
identifiable information that is collected, processed and transmitted in or from the governing jurisdiction. 
Since we collect, process and transmit personally identifiable information in and from numerous jurisdictions 
around the world, we are subject to privacy, data protection and data security legislation and regulations in 
a number of countries around the world. We are in particular affected by the GDPR. The GDPR applies to 
any company established in the EU as well as to those outside the EU if they collect and use personal data 
in connection with offering goods or services to individuals in the EU or the monitoring of their behavior (for 

19

example,  trip  booking  services).  The  GDPR  enhances  data  protection  obligations  for  processors  and 
controllers of personal data, including, for example, expanded disclosures about how personal information 
is to be used, limitations on retention of information, mandatory data breach notification requirements and 
onerous new obligations on services providers. Non-compliance with the GDPR can trigger significant fines 
of up to €20  million or 4% of total worldwide annual turnover, whichever is higher. We may incur substantial 
expense in complying with the new obligations to be imposed by the GDPR and we may be required to make 
significant changes in our business operations and product and services development, all of which may 
adversely affect our revenue and our business overall. We could be adversely affected if we fail to comply 
fully with all of these requirements and other laws in jurisdictions where we operate or target users. In addition, 
we could be adversely affected if legislation or regulations are expanded to require changes in our business 
practices or if governing jurisdictions interpret or implement their legislation or regulations in ways that may 
have a material adverse effect on our business, results of operations, financial condition and prospects.

In recent years, U.S. and European lawmakers and regulators have expressed concern over the use of third-
party  cookies,  web  beacons  and  similar  technology  for  online  advertising,  which  is  fundamental  to  our 
business  model.  The  current  European  laws  that  cover  the  use  of  cookies  and  similar  technology  and 
marketing  online  or by  electronic  means  are  under  reform.  Unlike  the  current  law,  the  new  proposed  e-
Privacy Regulation will apply directly in each EU member states, without the need for further enactment at 
the member state level. When implemented, the e-Privacy Regulation is expected to alter rules on third-
party cookies, web beacons and similar technology for online behavioral advertising and to impose stricter 
requirements on companies using these tools. The draft also extends the strict opt-in marketing rules with 
limited  exceptions  to  business-to-business  communications,  and  significantly  increases  penalties. 
Regulation of cookies and web beacons may lead to broader restrictions on our advertising activities, including 
efforts to understand users’ Internet usage. Such regulations may have a chilling effect on businesses, such 
as ours, that collect and use online usage information in order to attract and retain advertisers and may 
increase the cost of maintaining a business that collects or uses online usage information, increase regulatory 
scrutiny  and  increase  the  potential  for  civil  liability  under  consumer  protection  laws.  In  response  to 
marketplace  concerns  about  the  usage  of  third-party  cookies  and  web  beacons  to  track  user  behavior, 
providers of major browsers have included features that allow users to limit the collection of certain data in 
general or from specified websites, and some regulatory authorities have been advocating the development 
of  browsers  that  block  cookies  by  default.  These  developments  could  impair  our  ability  to  collect  user 
information  that  attracts  advertisers.  If  such  technology  is  widely  adopted,  it  could  adversely  affect  our 
business.

20

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 control over financial reporting, 
disclosure  control,  and  complying  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 since we ceased to qualify as an “emerging growth company” under the JOBS 
Act at the end of 2017. Satisfying these requirements required us to dedicate a significant amount of time 
and resources, including for the development, implementation, evaluation and testing of our internal control 
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, 2017, our management 
cannot guarantee that our internal control and disclosure controls will prevent all possible errors or all 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 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 could 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 are currently in the process of transitioning certain of our business and financial systems to systems on 
a  scale  reflecting  the  increased  size,  scope  and  complexity  of  our  operations,  particularly  including  the 
adoption and integration of a new internally developed tool to manage our invoicing, and various third-party 
developed tools to assist us with internal system integration, financial management, and consolidation. 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 the consolidation software relates to a wide variety of items in 
our financial statements that we report on a consolidated basis. In addition, while our financial management 
software is intended to increase accuracy of financial reporting and reduce our reliance on manual procedures 
and actions, the transition to that system can affect the accuracy of reporting as we align that system to our 
internal processes. This can affect a variety of parts of our revenue cycle, including recognition of revenue 
in accordance with our revenue recognition policy, deferred revenue, and accounts receivable. With respect 
to these systems, certain 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 results of operations or financial condition and cause harm to our reputation.

We rely on information technology to operate our businesses 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. 

21

Our  future  success  also  depends  on  our  ability  to  adapt  our  services  and  infrastructure  to  meet  rapidly 
evolving consumer trends and demands while continuing to improve the performance, features and reliability 
of our service in response to competitive service offerings. The emergence of alternative platforms such as 
smartphone and tablet computing devices and the emergence of niche competitors who may be able to 
optimize services or strategies such platforms have required, and will continue to require, new and costly 
investments in technology. We may not be successful, or we may be less successful than our current or new 
competitors, in developing technologies that operate effectively across multiple devices and platforms and 
that are appealing to users, either of which would negatively impact our business and financial performance. 
New developments in other areas, such as cloud computing and software-as-a-service providers, could also 
make it easier for competitors to enter our markets due to lower up-front technology costs. 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  in  a  cost-effective  manner.  Failure  to  invest  in  and  adapt  to  technological 
developments and industry trends may have a material adverse effect on our business, results of operations, 
financial condition and prospects. 

Any significant disruption in service on our websites and apps or in our computer systems, some 
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, and we may experience 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  our  services.  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. 

Substantially all of the communications, network and computer hardware used to operate our website are 
located at facilities in the Germany, United States, Hong Kong and China. We either lease or own our servers 
and have service agreements with data center providers. 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 and hardware 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, 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 by 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. 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. 

Changes in Internet browser functionality could result in a decrease in our overall revenue. 

We  generate  revenue,  in  part,  by  redirecting  users  to  our  advertisers’  websites.  Changes  in  browser 
functionality may either prevent or limit our ability to redirect users to our advertisers. As a result, our revenue 
could decline if we are no longer able to offer this feature to our users. 

22

The introduction of certain technologies may reduce the effectiveness of our services. For example, some 
of our services and marketing activities rely on cookies, which are placed on individual browsers when users 
visit websites. We use these cookies to optimize our marketing campaigns and our advertisers’ campaigns, 
to better understand our users’ preferences and to detect and prevent fraudulent activity. 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. Increased use of methods, software or apps that 
block cookies, or the disaffection of users resulting from our use of such marketing activities, may have an 
adverse effect on our business, results of operations, financial condition and prospects. 

Our brands are 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,  the independent  actors  we  rely  on in  various  countries  where  we advertise  have  come to 
represent our brand, such as “Mr. trivago” in the United States and “the trivago girl” in Australia. The actions 
of such actors are not in our control, and negative publicity about such actors could affect our brand image. 
Also, it is possible that the use of testimonials in the advertising and promotion of our brands could have a 
negative impact on customer retention and acquisition if the reputation of the testimonial provider is damaged. 
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 investigations or litigation relating 
to practices in our marketplace and related online travel-related market segments. 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. 

Many events beyond our control 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 other pandemics and epidemics, have disrupted normal travel patterns and 
levels in the past. The travel industry is also sensitive to events that may discourage travel, such as work 
stoppages or labor unrest, political instability, regional hostilities, 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.  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 involve additional risks, and our exposure to these risks will increase as our 
business continues to expand. 

We operate in a number of jurisdictions and intend to continue to expand our global presence, including in 
emerging markets. As of December 31, 2017, we derived 38% of our total referral revenue from our operations 
in the Americas, 42% of our revenue from our operations in Developed Europe and 20% of our revenue from 
our operations in the Rest of World. See “Item 5 Operating and financial review and prospects” for a further 
description of our geographical operating segments. We face complex, dynamic and varied risk landscapes 
in the jurisdictions in which we operate. As we enter countries and markets that are new to us, we must tailor 
our services and business models to the unique circumstances of such countries and markets, which can 
be  complex,  difficult,  costly  and  divert  management  and  personnel  resources.  In  addition,  we  may  face 
competition  in  other  countries  from  companies  that  may  have  more  experience  with  operations  in  such 

23

countries or with global operations in general. Laws and business practices that favor local competitors or 
prohibit  or  limit  foreign  ownership  of  certain  businesses  or  our  failure  to  adapt  our  practices,  systems, 
processes and business models effectively to the user and supplier preferences of each country into which 
we expand, could slow our growth. Certain markets in which we operate are characterized by lower margins 
in our business and related businesses than is the case in more mature markets, which could have a negative 
impact on our overall margins as our revenue from these markets grows over time. 

In addition to the risks outlined elsewhere in this section, our global operations are subject to a number of 
other risks, including: 

• 

• 

• 

• 

changing  political  conditions,  including  risk  of  rising  protectionism,  restrictions  on  immigration  or 
imposition of new trade barriers;

local  political  or  labor  conditions,  including  being  individually  targeted  by  local  regulators  or  being 
adversely affected by national labor strikes;

compliance  with  various  regulatory  laws  and  requirements  relating  to  anti-corruption,  antitrust  or 
competition, economic sanctions, data content and privacy, consumer protection, employment and labor 
laws, health and safety, and advertising and promotions; 

differences,  inconsistent  interpretations  and  changes  in  various  laws  and  regulations,  including 
international, national and local tax laws; 

•  weaker or uncertain enforcement of our contractual and intellectual property rights; 

• 

• 

• 

• 

preferences by local populations for local providers; 

slower adoption of the Internet as an advertising, broadcast and commerce medium and the lack of 
appropriate infrastructure to support widespread Internet usage in those markets; 

our ability to support new technologies, including mobile devices, that may be more prevalent in certain 
global markets; and

uncertainty regarding liability for services and content, including uncertainty as a result of local laws and 
lack of precedent.

Our global operations expose us to risks associated with currency fluctuations, which may adversely 
affect our business. 

We conduct a significant and growing portion of our business outside the Eurozone. As a result, we face 
exposure to movements in currency exchange rates around the world. These exposures 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 euros 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 increasingly global nature of our business have made hedging these exposures more 
complex. 

We are subject to risks associated with a corporate culture that promotes entrepreneurialism among 
its employees, decentralized decision making 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.  In  addition,  at  the  core  of  our  culture  is  allowing  our  employees  to  grow,  ensuring  that  they 

24

continuously accept new challenges and take on new responsibilities. This is reflected by our leadership 
framework, which was introduced in 2017. Under this framework, we encourage our employees to move 
into and out of newly defined leadership roles, and we rotate experienced employees to other jobs and 
different leadership roles within the company. 

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, which could have a material adverse effect on our business, results 
of operations, financial condition and prospects. 

We  rely  on  the  performance  of  highly  skilled  personnel,  including  senior  management  and  our 
technology professionals, and if we are unable to retain or motivate key personnel or hire, retain and 
motivate qualified personnel, 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. The loss of the services 
of any key individual could negatively affect our business. In particular, the contributions of certain key senior 
management are important to our overall success. 

On February 28, 2018, our supervisory board approved a new streamlined leadership structure at trivago. 
In accordance with this plan, we reduced the number of managing directors in the management board from 
six to three, and reduced the number of persons whom we consider part of our leadership team from seven 
to five. The reduction in the size of our leadership team increases our exposure to the risk that we would 
lose the services of one or more of the remaining members of the team. Should one or more of our senior 
managers leave our company, we might experience dislocations while a replacement or replacements are 
located and they are integrated into our company. Any phase of transition to new senior managers may be 
accompanied by slower or inconsistent decision-making, or to the diversion of management attention to 
matters relating to executive recruitment and integration. This could have a material adverse effect on our 
results of operations or damage our reputation. 

The Amended and Restated Shareholders’ Agreement contains certain provisions that could result in the 
departure of certain of our senior management, including if the Founders, collectively, hold less than 15% 
of our outstanding Class A shares and Class B shares (calculated as if all securities convertible, exercisable 
or exchangeable for Class A shares or Class B shares had been converted, exercised or exchanged), they 
lose certain contractual rights to nominate members of our management board. In such case, our supervisory 
board may also request from the Founders, the resignation of members of the supervisory board who have 
been nominated by the Founders. In addition, the general meeting of shareholders, which is controlled by 
Expedia,  has  broad  discretion  to  remove  members  of  our  management  board  with  and  without  cause, 
irrespective of the Founders’ holdings. If the general meeting of shareholders has reasonable cause, as 
defined in the Amended and Restated Shareholders’ Agreement, for such removal, Expedia has the unilateral 
right, subject to certain exceptions, to purchase all of such member’s shares. 

Our future success depends on our continuing ability to attract, develop, motivate and retain highly qualified 
and skilled employees. Competition for well-qualified employees in all aspects of our business, including 
software  engineers  and  other  technology  professionals  who  are  key  to  designing  code  and  algorithms 
necessary to our business, is intense globally. If we do not succeed in attracting well-qualified employees 
or retaining and motivating existing employees and key senior management, it may have a material adverse 
effect on our business, results of operations, financial condition and prospects.

25

The requirements of being a public company may strain our resources and distract our management, 
which  could  make  it  difficult  to  manage  our  business,  particularly  now  that  we  are  no  longer  an 
“emerging growth company.” 

As a public company with ADSs traded on an exchange located in the United States, we incur legal, accounting 
and other expenses resulting from the reporting requirements of the Exchange Act and the Sarbanes-Oxley 
Act, the listing requirements of Nasdaq, the Dutch Corporate Governance Code 2016, or the DCGC, and 
other applicable securities rules and regulations. Compliance with these rules and regulations have increased 
and will continue to increase our legal and financial compliance costs, make some activities more difficult, 
time consuming or costly and increase demand on our systems and resources, particularly now that we are 
no longer eligible for the exceptions from certain requirements available to “emerging growth companies” 
under the rules of the SEC. The Exchange Act requires that we file annual and current reports with respect 
to our business, financial condition and results of operations. The Sarbanes-Oxley Act requires, among other 
things,  that  we  establish  and  maintain  effective  internal  controls  and  procedures  for  financial  reporting. 
Furthermore,  establishing  the  corporate  infrastructure  demanded  of  a  public  company  may  divert  our 
management’s attention from implementing our growth strategy, which could prevent us from improving our 
business, financial condition and results of operations. We have made, and will continue to make, changes 
to our internal controls and procedures for financial reporting and accounting systems to meet our reporting 
obligations as a public company these rules and regulations have made it more difficult and more expensive 
for us to obtain director and officer liability insurance, and we may be required to incur substantial costs to 
maintain the same or similar coverage. These additional obligations could have a material adverse effect 
on our business, financial condition, results of operations and cash flow. 

In addition, changing laws, regulations and standards relating to corporate governance and public disclosure 
are creating uncertainty for public companies, increasing legal and financial compliance costs and making 
some  activities  more  time  consuming.  These  laws,  regulations  and  standards  are  subject  to  varying 
interpretations, in many cases due to their lack of specificity, and, as a result, their application in practice 
may evolve over time as new guidance is provided by regulatory and governing bodies. This could result in 
continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to 
disclosure and governance practices. We intend to invest resources to comply with evolving laws, regulations 
and standards, and this investment may result in increased general and administrative  expenses and a 
diversion of our management’s time and attention from revenue-generating activities to compliance activities. 
If our efforts to comply with new laws, regulations and standards differ from the activities intended by regulatory 
or governing bodies due to ambiguities related to their application and practice, regulatory authorities may 
initiate legal proceedings against us and our business, financial condition, results of operations and cash 
flow could be adversely affected. 

 We may lose our foreign private issuer status in the future, which could result in significant additional 
costs and expenses. 

We are a “foreign private issuer,” as such term is defined in Rule 405 under the Securities Act, and therefore, 
we  are  not required  to comply  with  all  the  periodic  disclosure  and  current reporting  requirements  of  the 
Exchange Act and related rules and regulations. Under Rule 405, the determination of foreign private issuer 
status is made annually on the last business day of an issuer’s most recently completed second fiscal quarter 
and, accordingly, the next determination will be made with respect to us on June 30, 2018. 

In the future, we would lose our foreign private issuer status if a majority of our shareholders, directors or 
management continue to be U.S. citizens or residents and we fail to meet additional requirements necessary 
to avoid loss of foreign private issuer status. Although we have elected to comply with certain U.S. regulatory 
provisions, our loss of foreign private issuer status would make such provisions mandatory. If we are not a 
foreign private issuer, we will be required to file periodic reports and registration statements on U.S. domestic 
issuer forms with the SEC, which are more detailed and extensive than the forms available to a foreign 
private issuer. For example, the annual report on Form 10-K requires domestic issuers to disclose executive 
compensation  information  on  an  individual  basis  with  specific  disclosure  regarding  the  domestic 
compensation  philosophy,  objectives,  annual  total  compensation  (base  salary,  bonus  and  equity 
compensation) and potential payments in connection with change in control, retirement, death or disability, 

26

while  the  annual  report  on  Form  20-F  permits  foreign  private  issuers  to  disclose  considerably  less 
compensation-related information. We will also have to comply with U.S. federal proxy requirements, and 
our officers, directors and principal shareholders will become subject to the short-swing profit disclosure and 
recovery provisions of Section 16 of the Exchange Act. We may also be required to modify certain of our 
policies to comply with good governance practices associated with U.S. domestic issuers. In addition, we 
may lose our ability to rely upon exemptions from certain corporate governance requirements on U.S. stock 
exchanges that are available to foreign private issuers. We would need to convert our systems to prepare 
our financial statements in U.S. dollars. Such conversion and modifications will involve additional costs and 
may divert our management’s attention from other business concerns, which could have a material adverse 
effect on our business, financial condition, results of operations and cash flows. 

Integration of acquired assets and businesses could result in operating difficulties and other harmful 
consequences. 

in 

We  have  acquired  businesses 
the  past,  comprising  myhotelshop  GmbH,  or  myhotelshop, 
base7booking.com S.à r.l., or base7, B264 GmbH, or Rheinfabrik, and tripl GmbH, or tripl. 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 potential acquisitions and subsequent integrations 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 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 timelines 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. 

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 

27

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 have historically been very low. Because a majority of our accounts receivable are 
owed by three large OTAs, 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. In addition, as we seek to expand 
our advertiser base to include more direct hotel advertisers, alternative accommodation providers and other 
advertisers beyond our core OTA base, we may increase or exposure to counterparties that may fail to pay 
us. These 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. In the event of such default, we could incur significant losses, which could 
adversely impact our business, results of operations, financial condition and prospects. 

Risks related to our ongoing relationship with our shareholders 

Expedia controls our company and has the ability to control the direction of our business. 

As of December 31, 2017, Expedia owned Class B shares representing 59.6% of our issued share capital 
and 64.7% of the voting power in us. As long as Expedia owns a majority of the voting power in us, and 
pursuant to certain rights it has under the Amended and Restated Shareholders’ Agreement, Expedia 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 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 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. 

The Founders have contractual rights to exert control over certain aspects of our business. 

As of December 31, 2017, the Founders owned 31.6% of our outstanding Class A shares and Class B shares. 
Pursuant to the Amended and Restated Shareholder’s Agreement, the Founders have contractual rights to 
exert control over certain aspects of our business. For example, as long as the Founders collectively maintain 
holdings of at least 15% of our outstanding Class A shares and Class B shares (taking into account, for 
purposes of determining such percentage, each security convertible into or exchangeable for, and any option, 
warrant, or other right to purchase or otherwise acquire, any Share), the Founders will have certain rights 
to veto decisions about certain corporate matters. These contractual rights limit the ability of Expedia to 
control certain corporate matters and, as a result, we may fail to take actions that other shareholders may 
view as beneficial. This contractual control may also discourage transactions involving a change of control 
or sale of substantially all assets 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 or dividend of proceeds 
representing a premium price for such assets. Furthermore, subject to certain exceptions, so long as the 
Founders collectively maintain holdings of at least 15% of our outstanding Class A and Class B shares (taking 
into account, for purposes of determining such percentage, each security convertible into or exchangeable 
for, and any option, warrant, or other right to purchase or otherwise acquire, any Share), the Founders who 
are then serving as managing directors have the ability to select the other managing directors and, as a 
result, the Founders and their appointees will comprise the body that has primary day-to-day operational 
control of the company. In addition, from the date that Mr. Schrömgens ceases to serve as chief executive 
officer for a period of three years, so long as a Founder is serving as chief executive officer and there is no 
set of circumstances that would constitute a reasonable cause, such Founder has the right to nominate a 

28

successor in its function of chief executive officer, subject to the approval of Expedia and thereafter, the 
supervisory board. 

Expedia’s interests may conflict with our interests, the interests of the Founders and the interests 
of our shareholders, and conflicts of interest between Expedia, the Founders and us could be resolved 
in a manner unfavorable to us and our shareholders. 

Various  conflicts  of  interest  between  us,  the  Founders  and  Expedia  could  arise.  Ownership  interests  of 
directors or officers of Expedia in our shares and ownership interests of members of our management board 
and supervisory board in the stock of Expedia, or a person’s service as either a director or officer of both 
companies, could create or appear to create potential conflicts of interest when those directors and officers 
are faced with decisions relating to our company. In the years ended December 31, 2015, 2016 and 2017, 
Expedia, and brands affiliated with Expedia, accounted for 39%, 36% and 36% of our revenue, respectively. 

Potential conflicts of interest could also arise if we decide to enter into any new commercial arrangements 
with Expedia’s businesses in the future or in connection with Expedia’s desire to enter into new commercial 
arrangements with third parties. 

Expedia has the right to pursue acquisitions of businesses that trivago may also be interested in acquiring 
and the right to acquire companies that may directly compete with us. Expedia may choose to pursue these 
corporate opportunities other than through trivago. 

Furthermore, disputes may arise between Expedia 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 agrees to provide to us; 

sales, other disposals, purchases or other acquisitions by Expedia of shares in us (including when our 
share price is lower than in comparable periods); and 

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, 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 with an unaffiliated third party. In addition, should Expedia choose not to guarantee any 
future indebtedness we may incur, the cost of such financing may increase or financing may not be available 
at all. 

Risks related to our intellectual property 

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 as critical to our success, and we rely on trademark and confidentiality 
and license agreements 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 and financial condition. 

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 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. 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 

29

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 and www.trivago.co.uk. If we lose the ability to use a domain name, we would be forced to 
incur significant expenses to market our services under a new domain name, which could substantially harm 
our  business.  In  addition,  our  competitors  could  attempt  to  capitalize  on  our  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 top-level domain name “trivago” is 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. 

Claims by third parties that we infringe on their intellectual property rights could result in significant 
costs and have a material adverse effect on our business, results of operations or financial condition. 

From time to time, we could be subject to various patent and trademark infringement claims. These claims 
could allege, among other things, that our website technology infringes upon owned patented technology 
and/or trademarks of third parties. If we are not successful in defending ourselves against these claims, we 
may be required to pay monetary damages, which could have an adverse effect on our results of operations. 
In addition, the costs associated with the defense of these claims could have an adverse effect on our results 
of operations. As we grow our business and expand our operations, we expect that we will continue to be 
subject to intellectual property claims. Resolving intellectual property claims may require us to obtain licenses 
to use intellectual property rights belonging to third parties, which may be expensive to procure, or we may 
be required to cease using intellectual property of third parties altogether. Any of these events may have a 
material adverse effect on our business, results of operations, financial condition and prospects. 

Confidentiality agreements with employees and others may not adequately prevent disclosure of 
trade secrets and other proprietary information. 

A substantial amount of our processes and technologies is protected by trade secrecy laws. In order to 
protect these technologies and processes, we rely in part on confidentiality agreements with our employees, 
licensees,  independent  contractors  and  other  advisors.  These  agreements  may  not  effectively  prevent 
disclosure of confidential information, including trade secrets, and may not provide an adequate remedy in 
the  event  of  unauthorized  disclosure  of  confidential  information.  In  addition,  others  may  independently 
discover our trade secrets and proprietary information, and in such cases we could not assert any trade 
secrecy rights against such parties. To the extent that our employees, contractors or other third parties with 
which  we  do  business  may  use  intellectual  property  owned  by  others  in  their  work  for  us  without  our 
authorization, disputes may arise as to the rights in related or resulting know-how and inventions. Laws 
regarding trade secrecy rights in certain markets in which we operate may afford little or no protection to our 
trade secrets. The loss of trade secret protection could make it easier for third parties to compete with our 
services by copying functionality. In addition, any changes in, or unexpected interpretations of, the trade 
secret and other intellectual property laws in any country in which we operate may compromise our ability 
to enforce our trade secret and intellectual property rights. Costly and time-consuming litigation could be 
necessary to enforce and determine the scope of our proprietary rights, and failure to obtain or maintain 
trade secret protection may have a material adverse effect on our business, results of operations, financial 
condition and prospects. 

Our use of “open source” software could adversely affect our ability to offer our services and subject 
us to possible litigation. 

We use open source software in connection with our development. From time to time, companies that use 
open source software have faced claims challenging the use of open source software or compliance with 

30

open source license terms. We could be subject to suits by third parties claiming ownership of what we 
believe to be open source software, or claiming non-compliance with open source licensing terms. Some 
open source licenses require users who distribute software containing open source to make available all or 
part of such software, which in some circumstances could include valuable proprietary code of the user. 
While we monitor the use of open source software and try to ensure that none is used in a manner that would 
require us to disclose our proprietary source code or that would otherwise breach the terms of an open 
source agreement, such use could inadvertently occur, in part because open source license terms are often 
ambiguous. Any requirement to disclose our proprietary source code or pay damages for breach of contract 
may have a material adverse effect on our business, results of operations, financial condition and prospects 
and could help our competitors develop services that are similar to or better than ours. 

Risks related to ownership of our Class A shares and ADSs 

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, in part because our ADSs 
have little history of being publicly traded and there have been relatively few ADSs outstanding. 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 paid to us by our customers or of our competitors;

our involvement in litigation;

our sale of ADSs or other securities 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 experienced extreme price and volume fluctuations that have 
affected and continue to affect the market prices of equity securities of many Internet 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. 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, which will 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. 

31

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 
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  do  not  continue  to  publish  research  or  publish  inaccurate  or 
unfavorable research about our business, our ADS price and trading volume 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. If one or more of these analysts cease coverage of us or fail to publish reports on us regularly, 
demand for our ADSs could decrease, which could cause our ADS price and trading volume to decline. 

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 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. 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 

32

 
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. 

You may be subject to limitations on the transfer of your ADSs. 

Your ADSs, which may be evidenced by ADRs, 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 and growth of 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.  See  “Item  16  G.  Corporate 
governance.”

We are not obligated to and do not comply with all the best practice provisions of the Dutch Corporate 
Governance Code. 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. 

See “Item 16 G. Corporate governance.” 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. 

33

Our dual-class share structure with different voting rights, and certain provisions in the Amended 
and Restated Shareholders’ Agreement, 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, 2017, Expedia owned Class B shares representing 59.6% of our share capital and 
64.7% of the voing power in us, and the Founders owned Class B shares representing 31.6% of our share 
capital and 34.3% of the voting power in us due to the disparate voting powers associated with our dual-
class  share  structure.  See  “Item  7  A.  Major  shareholders  and  related  party  transactions—Major 
shareholders.” As a result of the dual-class share structure and the concentration of ownership, as well as 
the  terms  of  the  Amended  and  Restated  Shareholders’  Agreement,  Expedia  and  the  Founders  have 
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, Council Regulation (EC) 
No. 1346/2000  of  May 29,  2000  on  insolvency  proceedings  (which  has  been  replaced  by  Regulation 
(EU) 2015/848 of the European Parliament and of the Council of May 20, 2015 on insolvency proceedings 
as of June 2017). Should courts in another European country determine that the insolvency laws of that 
country 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 a dual-class share structure 
that gives greater voting power to the Class B shares owned by Expedia 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. 

34

U.S. investors may have difficulty enforcing civil liabilities against us or members of our management 
board and supervisory board. 

We are incorporated in the Netherlands. Most members of our management board and supervisory board 
are non-residents of the United States. The majority of our assets and the assets of these persons are located 
outside the United States. As a result, it may not be possible, or may be very difficult, to serve process on 
such persons or us in the United States or to enforce judgments obtained in U.S. courts against them or us 
based on civil liability provisions of the securities laws of the United States. 

There is no treaty between the United States and the Netherlands for the mutual recognition and enforcement 
of judgments (other than arbitration awards) in civil and commercial matters. Therefore, a final judgment for 
the payment of money rendered by any federal or state court in the United States based on civil liability, 
whether  or  not  predicated  solely  upon  the  U.S.  federal  securities  laws,  would  not  be  enforceable  in  the 
Netherlands unless the underlying claim is relitigated before a Dutch court of competent jurisdiction. Under 
current  practice,  however,  a  Dutch  court  will  generally,  subject  to  compliance  with  certain  procedural 
requirements, grant the same judgment without a review of the merits of the underlying claim if such judgment 
(i) is a final judgment and has been rendered by a court which has established its jurisdiction vis-à-vis the 
relevant Dutch Companies or Dutch Company, as the case may be, on the basis of internationally accepted 
grounds of jurisdiction, (ii) has not been rendered in violation of elementary principles of fair trial, (iii) is not 
contrary to the public policy of the Netherlands, and (iv) is not incompatible with (a) a prior judgment of a 
Netherlands court rendered in a dispute between the same parties, or (b) a prior judgment of a foreign court 
rendered in a dispute between the same parties, concerning the same subject matter and based on the 
same cause of action, provided that such prior judgment is capable of being recognized in the Netherlands. 
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. 

Based on the foregoing, there can be no assurance that U.S. investors will be able to enforce any judgments 
obtained in U.S. courts in civil and commercial matters, including judgments under the U.S. federal securities 
laws, against us or members of our management board and supervisory board, officers or certain experts 
named herein who are residents of the Netherlands or countries other than the United States. In addition, 
there is doubt as to whether a Dutch court would impose civil liability on us, the members of our management 
board and supervisory board, our officers or certain experts named herein in an original action predicated 
solely upon the U.S. federal securities laws brought in a court of competent jurisdiction in the Netherlands 
against us or such members, officers or experts, respectively. 

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  16  G.  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.

35

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, 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  of  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. 

Furthermore, because we qualify as a foreign private issuer under the Exchange Act, we are exempt from 
certain provisions of the Exchange Act that are applicable to U.S. public companies, including (i) the sections 
of the Exchange Act regulating the solicitation of proxies, consents or authorizations in respect of a security 
registered under the Exchange Act, (ii) the sections of the  Exchange Act requiring  insiders to file public 
reports of their share ownership and trading activities and liability for insiders who profit from trades made 
in a short period of time and (iii) the rules under the Exchange Act requiring the filing with the SEC of quarterly 
reports on Form 10-Q containing unaudited financial and other specified information, or current reports on 
Form 8-K, upon the occurrence of specified significant events. As a result, you may not be provided with the 
same benefits as a holder of shares of a U.S. issuer. 

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 intend to have, 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. By 
reason of our incorporation under Dutch law, we are also deemed tax resident in the Netherlands under 
Dutch national tax laws. However, based on our current management structure and 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 tax laws, tax treaties or interpretations thereof applicable to us 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 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), may result in us becoming a tax resident of a jurisdiction other than Germany, potentially 
also triggering an exit tax liability in Germany. As a consequence, our overall effective income tax rate and 
income tax expense could 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 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 
36

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 cash flows, 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 Internet and e-commerce. 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, in October 
2015, the Organization for Economic Co-Operation and Development released a final package of measures 
to be implemented by member nations in response to a 2013 action plan calling for a coordinated multi-
jurisdictional approach to “base erosion and profit shifting” by multinational companies. Multiple member 
jurisdictions, including the countries in which we operate, have begun implementing recommended changes, 
such as proposed country-by-country reporting beginning as early as 2016. In June 2017, almost 70 member 
jurisdictions have ratified the “Multilateral Convention to Implement Tax Treaty Related Measures to Prevent 
Base  Erosion  and  Profit  Shifting”. Additional  multilateral  changes  are  anticipated  in  upcoming  years  in 
connection  with  the  action  plan  against  “base  erosion  and  profit  shifting”  and  other  multi-jurisdictional 
measures and initiatives like the Anti-Tax Avoidance Directive I and the Anti-Tax Avoidance Directive II of 
the European Union. In addition, there have been also developments in the national level in many countries 
that have targeted the digital economy. Any changes to national or international tax laws could impact the 
tax  treatment  of  our  earnings  and  adversely  affect  our  profitability.  We  continue  to  work  with  relevant 
authorities and legislators to clarify our obligations under existing, new and emerging tax laws and regulations. 
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, changes in the valuation of 
deferred tax assets and liabilities, or the discontinuation of beneficial tax arrangements in certain jurisdictions. 

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 expect to be treated as a PFIC for U.S. federal income tax purposes for the current taxable year or in 
the foreseeable future. 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. 
Therefore, there can be no assurance that we will not be classified as a PFIC for the current taxable year 
or for any future taxable year. We would be classified as a PFIC for any taxable year 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 “Material tax considerations-Material U.S. 

37

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, which is generally 
15%, however, by an application filed by the tax payer containing 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 and 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 withholding, which could 
mean that a dividend is effectively taxed twice. The company has listed ADSs 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 Depository 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 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 E. Taxation—German taxation—German taxation of ADS 
holders”).

If we pay dividends, we may need to withhold tax on such dividends payable to holders of our ADSs 
in both Germany and the Netherlands. 

As an entity incorporated under Dutch law, but with its place of effective management in Germany (and not 
in the Netherlands), our dividends are generally subject to German dividend withholding tax and not Dutch 
withholding tax. However, Dutch dividend withholding tax is 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, 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 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 assessed upon a payment of 
dividend, withholding of both German and Dutch dividend tax from such dividend may occur.

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 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 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 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 
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 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 Bennigsen-Platz  1, 40474  Düsseldorf,  Germany (under  number HRB 79986).  Our 
telephone number is +49-211-3876840000.

Our agent in the United States is Cogency Global Inc., and its address is 10 East 40th Street, 10th floor, 
New York, NY 10016.

Principal capital expenditures and divestitures 

Although our growth has primarily been organic, we have made the following small strategic acquisitions 
since January 1, 2015: 

• 

• 

In July 2015, we acquired 61.3% of the equity of myhotelshop, a German online marketing management 
service provider for hotels, for a total purchase consideration of €0.6  million consisting of cash and the 
settlement of pre-existing debt at the closing of the acquisition. On December 15, 2017, myhotelshop 
GmbH issued 8,074 new myhotelshop common shares for a total of €0.1  million to a minority shareholder, 
who  was  and  continues  to  be  an  unrelated  party  to  trivago. This  capital  infusion  diluted  our  share  in 
myhotelshop from 61.3% to 49.0%. Following the increase in capital, in addition to the removal of certain 
put/call rights and other changes made through the capital infusion, we lost our controlling financial interest 
in myhotelshop. 

In August  2015,  we  acquired  52.3%  of  the  equity  of  base7booking,  a  Swiss  cloud-based  property 
management service provider for hotels, for total purchase consideration of €2.1  million in cash, which 
was concluded to create synergies with our rate connect offerings. The operations of base7booking were 
subsequently transferred to Germany. On December 22, 2016, we exercised our call option in order to 
purchase  the  remaining  47.7%  noncontrolling  interest  in  base7booking  for  a  cash  consideration  of 
approximately €0.9  million. As such, we became the sole owner of base7booking. 

• 

In August 2017, we acquired all material assets of tripl, a German online platform for personal travel 
recommendations, for a total purchase consideration of €0.7  million, consisting of cash and trivago N.V. 
shares. tripl was acquired to enhance our product with personalization technology that uses big data and 

39

a customer-centric approach. tripl's algorithm gives users tailored travel recommendations by identifying 
trends  in  users'  social  media  activities  and  comparing  it  with  in-app  data  of  like-minded  users.  The 
alternative intelligence-driven product is designed to imitate the way a travel agent would recommend 
hotel experiences relevant to the customer, and combines it with the ease of online services.

These acquisitions were conducted with no external financing. 

Public takeover offers

Since January 1, 2017, there have been no public takeover offers by third parties with respect to our shares, 
and we have not made any public takeover offers in respect of any other company’s shares.

Segment reporting

Beginning  in  the  second  quarter  of  2016,  management  identified  three  reportable  segments,  which 
correspond to our three operating segments: the Americas, Developed Europe and the Rest of World. The 
change from one to three reportable segments was the result of a management reorganization to more 
effectively manage the business. This reorganization was performed to align the management of the business 
to our focus on unique market opportunities and competitive dynamics inherent within each of the operating 
segments. Our Americas segment is comprised of Argentina, Brazil, Canada, Chile, Columbia, 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 Australia, Japan, India, New Zealand and Hong Kong. Segment 
revenue is comprised entirely of referral revenue. Other revenue is included in Corporate and eliminations, 
along with all corporate functions and expenses except for direct advertising. 

We determined our operating segments based on how our chief operating decision makers manage our 
business, make operating decisions and evaluate operating performance. Our primary operating metric is 
return  on  advertising  spend,  or  ROAS,  for  each  of  our  segments,  which  compares  referral  revenues  to 
advertising spend.

B. Business overview

Overview 

trivago is a global hotel search platform. We are focused on reshaping the way travelers search for and 
compare hotels, while enabling hotel advertisers to grow their businesses by providing access to a broad 
audience of travelers via our websites and apps. Our platform allows travelers to make informed decisions 
by personalizing their hotel search and providing access to a deep supply of hotel information and prices. 
In the year ended December 31, 2017, we had 727.1 million Qualified Referrals and offered access to more 
than 1.8 million hotels and other types of accommodation in over 190 countries. See “Item 5 Operating and 
financial review and prospects” for a further description of qualified referrals. 

We have positioned our brand as a key part of the process for travelers in finding their ideal hotel. Our fast 
and intuitive hotel search platform enables travelers to find their ideal hotel by matching individual traveler 
preferences with detailed hotel characteristics, such as price, location, availability, amenities and ratings, 
across a vast supply of accessible hotels globally. 

We believe that the number of travelers accessing our websites and apps makes us an important and scalable 
marketing  channel  for  our  hotel  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. We generate revenues primarily 
on a “cost-per-click,” or CPC, basis, whereby an advertiser is charged when a user clicks on an advertised 
rate for a hotel and is referred to that advertiser’s website where the user can complete the booking. The 
CPC bids submitted by our advertisers play an important role in determining the prominence given to offers 
and their placement in our search results. Our CPC bidding function enables advertisers to influence their 
own return on investment and the volume of referral traffic we generate for them. 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 search platform can be accessed globally via 55 localized websites and apps in 33 languages. 
Users can search our platform on desktop and mobile devices, but benefit from a familiar user interface, 
resulting in a consistent user experience. In year ended December 31, 2017, our revenue share from mobile 
websites and apps exceeded 60%.

We have grown significantly since our incorporation in 2005. In the years ended December 31, 2015, 2016
and 2017, we generated revenue of € 493.1 million, € 754.2 million and € 1,035.4 million respectively. During 
the same periods, we had net losses of € (39.4) million, € (51.4) million and € (13.0) million, respectively. In 
the years ended December 31, 2015, 2016 and 2017, our adjusted EBITDA was €(1.1)  million, €28.2  million
and €6.7  million, respectively. See "Item 5 Operating review—Results of operations—Revenue" for referral 
revenue by segment, representing a breakdown according to principal geographic markets. See “Item 3 A. 
Key  information—Selected  financial  data”  for  an  additional  description  of  adjusted  EBITDA  and  a 
reconciliation of adjusted EBITDA to net loss.

trivago's search platform

We believe that we are reshaping hotel discovery for our users, while changing the way hotel advertisers 
identify, engage with and acquire travelers. Our search platform forms the core of our user experience, and 
can be accessed globally via 55 localized websites and apps in 33 languages. As we provide a hotel search 
website, users do not book directly on our platform. When they click on an offer for a hotel room 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 hotels in the world. As of December 31, 2017, our database 
included  more  than 1.8  million hotels  and  other  types  of  accommodation,  gathered  through  OTAs,  hotel 
chains, independent hotels and providers of alternative accommodations.

41

 
Our users initially search via a text-based search function, which supports searches across a broad range 
of criteria. This leads through to a listings page that displays search results and allows for further refinement 
based on more nuanced filters. Our platform organizes a large amount of information from multiple sources 
and gives each user what we believe to be the optimal basis to make a decision. We help users to convert 
initial interest into a clear and specific booking intention. 

Additionally, we enhance our users’ experience by giving them the choice to display their search results in 
listings or map formats. Users can search our platform on desktop and mobile devices, and benefit from a 
familiar user interface, resulting in a consistent user experience.

Performing a search shows a user a hotel listing page. This page contains broad, aggregated information, 
including: 

•  Hotel information: We display information that we believe is relevant to the user, such as the hotel 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. 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, while also listing 
additional available offers from our advertisers in a list format, including room types, amenity and payment 
options. To learn more about how we select this suggested deal, see "—Marketplace" below.

Our products are accessible anytime and anywhere, online and on mobile devices. We provide our services 
through mobile websites and apps. m.trivago.com is our mobile-optimized website available on mobile device 
browsers, and our full-featured native mobile app is available on iPhone, iPad, Android Phone and Android 
Tablet.

Product changes in 2017

Below are some of the more significant developments in our search product during 2017:

•  Optimization of our back-end structure to accelerate future product improvements. We reorganized 
our hotel search team to focus on separating user interface aspects from the service layer that connects 
the user interface to our back-end systems. While we made only small changes to the user interface, we 
believe the strengthening of our infrastructure will create a foundation for growth and scalability of new 
technology in the long term.

• 

Introduction of the "boundless maps" feature, which gives users a more fluid navigation experience 
when finding hotels in map view. The map reloads automatically as the user scrolls to view hotels by 
location. 

•  Other product changes. We also made improvements to the user interface with a simplified rating scale 
and the introduction of tabs for slide-outs. To better show our images, we integrated a new gallery and 
tagged our images to present the most relevant content to our users.

In 2017, we also continued to implement measures aimed at optimizing our platforms and product, with the 
intention  of  increasing  user  retention  and  booking  conversion,  while  reducing  the  number  of  click-outs 
required to ultimately make a booking. These are relatively small, incremental changes to our product that 
we believe, when considered together, will result in improvements to our product and platform. Since we 
make these changes by optimizing for traffic quality instead of volume, these changes will tend to have a 
negative impact on the number of Qualified Referrals, but we believe advertisers will increase their CPC 
bids in response to improved traffic quality in terms of booking conversion, which would have a long-term 
positive impact on Revenue per Qualified Referral (RPQR).

Alternative accommodation

On November 7, 2017, we started the technical integration of HomeAway's vacation rental inventory into 
our hotel search platform, running tests relating to the integration in Germany, Italy, Canada, the United 
Kingdom and the United States. We plan to gradually roll out additional readily bookable vacation rentals 
during  the  course  of  2018.  Vacation  rentals  are  part  of  our  alternative  accommodation  inventory,  which 
complements our hotel offering. We are in the process of integrating this inventory with the aim of making 
it a part of our universal search experience. As of December 31, 2017, over 250,000 units of alternative 
accommodation were available on our platform. For us, this was another major step forward in adapting to 
more diverse traveler expectations and in understanding better how to display vacation rental inventory on 
our platform. This integration opened a new marketing channel for vacation rental platforms and increased 
diversity in our marketplace. 

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. We organize our marketing teams and spend allocations to focus on 
building effective messaging to a broad audience across multiple geographies and languages. We believe 
that  building  and  maintaining  the  brand  and  clearly  articulating  our  our  role  in  travelers'  hotel  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.

43

Brand marketing

To grow brand awareness and increase the likelihood that users will visit our websites and apps, we invest 
in brand marketing globally across a broad range of media channels, including TV marketing, video marketing 
(such as YouTube) and out-of-home advertising.

The amount and nature of our marketing spend varies across our markets, depending on multiple factors, 
including cost efficiency, local media dynamics, the size of the market and our existing brand presence in 
that market.

We also generate hotel content as a means of engaging with travelers, which is distributed online including 
via social media. Mobile app marketing is becoming increasingly important with the continuous shift from 
desktop to mobile.

Performance marketing

We market our services and directly acquire traffic to 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 Baidu, Bing, Google and Yahoo! 
(commonly referred to as Search Engine Marketing or SEM), as well as through display advertising campaigns 
on advertising networks, affiliate websites and social networking sites (commonly referred to as Display, 
Email and Affiliate Advertising or DEA).

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.

In 2017, we started the implementation of our new model for allocating our marketing spend, which we refer 
to as our attribution model, with the aim of optimizing our investment mix going forward by focusing less on 
revenue generated in each user session and more on the end-to-end booking value of the user that we 
generate through our platform. The new attribution model focuses on whether a user who comes to us from 
a performance marketing channel proceeds to book a hotel, and reflects changes in how we determine 
whether revenue originated from a given marketing channel (or how revenue is “attributed” to that channel 
in  our  internal  metrics),  and  informs  decisions  we  make  about  how  much  we  spend  on  each  marketing 
channel.

In the third quarter, we completed the roll-out of this new attribution model in our DEA channel, after which 
we started to implement the new attribution model in our SEM channel. Following the roll-out of the new 
attribution model in our DEA channel in the third quarter, we experienced higher volatility and a slowdown 
in Qualified Referral growth compared to prior periods. We expect similar effects in the near-term resulting 
from the implementation of the new model in our SEM channel, but we believe this change will improve traffic 
quality in terms of booking conversion, which will have a long-term positive impact on advertisers' CPC bids 
and Revenue per Qualified Referral, or RPQR. For more information on Qualified Referrals and RPQR, see 
"Item 5 Operating and financial review and prospects—Operating result—Key factors affecting our financial 
condition and results of operations."

Advertiser relations

Our advertiser relations team seeks to provide tailored advice to each of our existing and prospective OTA, 
hotel chain and independent hotel advertisers. We have dedicated sales teams that manage the process of 
onboarding advertisers, maintain ongoing relationships with advertisers, work with advertisers to ensure 
they are optimizing their outcomes from the trivago platform and provide guidance on additional tools and 
features that could further enhance advertisers’ experience. 

44

We aim to remain in close dialogue with OTAs and sophisticated hotel chains to better understand each 
advertiser’s specific needs and objectives in order to offer optimal solutions through our marketplace.  

Relationship building with smaller advertisers, including some independent hotels, differs from those with 
OTAs and sophisticated hotel chains as they are often less familiar with CPC bidding models and online 
advertising more broadly. This typically ensures a longer sales cycle where the starting point can be building 
awareness of the relevance of our marketplace or articulating the opportunities that our independent platform 
offers. It often requires onboarding by encouraging the optimization of their information and profiles on our 
site, upselling products to further enhance their profiles, and encouragement to start bidding directly on our 
marketplace. This often multi-stage process requires our sales team to develop close relationships with each 
hotel. As of December 31, 2017, over 400,000 hotels engaged through Hotel Manager (described below) 
directly with our platform (as of December 31, 2016: 240,000), of which over 45,000 subscribed to Hotel 
Manager Pro (as of December 31, 2016: 30,000).

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. The following tools and services provide tailored solutions for OTAs, hotel chains 
and independent hotels to help them manage their presence on our marketplace and steer their investments 
according to their budget and traffic needs. Our tools include: 

trivago Hotel Manager, a marketing platform that gives each hotelier control over its hotel profile. 

• 

• 

• 

trivago Hotel Manager “Basic,” a free administration tool specifically for hotels, helping them build and 
manage a unique hotel profile on trivago to enhance their presence. This includes the ability to manage 
visual and static content, including adjusting contact details, pictures, amenities and service listings, as 
well as refining descriptions. Using the Hotel Manager tool, each hotel can ensure that our marketplace 
accurately captures their offerings, helping attract guests. 

trivago Hotel Manager “Pro,” which is sold on a one-year subscription basis and allows hotels to enhance 
their profile with more advanced features and functionalities. With Hotel Manager Pro, hotels can increase 
promotion with exclusive news about their hotel and prominent contact details, helping them stand out 
and drive more bookings. Furthermore, we provide hoteliers with additional analytics about who searches 
for them as well as benchmarking against their competition. 

trivago Hotel Manager “Rate Connect,” which enables independent hotels to publish their website rates 
directly on their profiles, helping them to increase direct bookings and their prominence in our marketplace. 
Hotels set a monthly budget, and we create an optimized marketing campaign, automatically calculating 
CPC bids that are competitive with other advertisers and targeted to increase referrals. A dedicated team 
of marketing experts is available via email or phone to support hotels.

trivago Intelligence, a marketing platform for multi-property management that enables hotel chains and OTAs 
to manage their inventory and CPCs. 

• 

trivago Intelligence, which provides holistic control for our advertisers that wish to closely manage and 
analyze their advertising on our marketplace. It allows them to bid on individual hotels with a high degree 
of granularity and control, provides metrics and feedback on specific advertising campaigns and offers 
advice to optimize bidding strategy and drive additional referrals. 

•  Automated Bidding, which allows OTAs, hotel chains and independent hotels to bid efficiently on listings. 
Advertisers are able to decide the traffic volumes or return on advertising investment they wish to reach 
and the tool will automatically set and adjust bids according to the target. We believe this is an especially 
valuable tool for advertisers that are less familiar with online bidding models, although it is our belief that 
larger, more experienced advertisers will also value the efficiency Automated Bidding provides. 

•  Express Booking, which is developed to help our advertisers drive bookings by providing the option of an 
easy booking method within our marketplace. Although the booking information is completed on our site, 
the advertiser processes payment directly, confirms the booking and provides any booking support. We 

45

also prominently feature the brand of the advertiser taking the booking, allowing our advertisers to continue 
to build their own brand within our marketplace. 

•  Direct Connect for Chains, which enables hotel chains to publish rates from their website directly on their 
inventory using their existing Central Reservation System and Internet Booking Engine. This helps them 
increase direct bookings and their prominence on our marketplace. Hotel chains that run direct connect 
campaigns also get access to Automated Bidding and Express Booking tools. 

Marketplace 

We design our algorithm to showcase the hotel room rate offers that we believe will be of most interest to 
our users, emphasizing those offers that are more likely to be clicked and ultimately booked on our advertisers' 
websites. We consider the completion of hotel bookings, which we refer to as conversion, to be a key indicator 
of user satisfaction on our website. At the core of our ability to match our users’ searches with large numbers 
of hotel 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. Advertisers do this by submitting hotel room rates on our marketplace and 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 rates and availability on a near-real time basis. 

In determining the prominence given to offers and their placement in our search results, including in hotel 
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 the advertiser’s 
offered rate for the hotel room, the likelihood the offer will match the user’s hotel search criteria, data we 
have collected on likely booking conversion and user experience (as reflected in our relevance assessment) 
and the CPC bids submitted by our advertisers. 

The CPC bids submitted by our advertisers 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.  Generally,  the  higher  the  potential  booking  value  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. 
This means that the levels of advertisers’ CPC bids 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 hotel room inventory that the advertiser has for some 
period of time withdrawn from its active inventory on trivago.

Our relevance assessment focuses on the quality of users' experience after clicking out to an advertiser 
from  our  website.  The  relevance  assessment  approximates  the  relative  ease  or  difficulty  for  users  of 
completing a booking on our advertisers’ websites and advantages that advertisers might derive from non-
standard website designs, and then results in an upward or downward adjustment to those advertisers’ CPC 
bids in our marketplace's auction process based on that evaluation, which in turn can affect the prominence 
given to the offers in our search results (with offers more likely to lead to a booking given greater prominence). 
During the fourth quarter of 2017, we upgraded our relevance assessment, by introducing an automated 
calculation, new factors to approximate the user experience and general optimizations of the algorithm.

By managing their CPC bids, relevance assessments and hotel room 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  tools  and  services,  such  as  our Automated  Bidding  tool,  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. 

46

As mentioned under “—trivago’s search platform” above, we prominently display a suggested deal for each 
hotel, which is determined based on our algorithm as described above, while also listing additional offers 
made available to us from our advertisers in a list format. In late 2017, we started to roll out a broadened 
selection of offers we display and modified how we display them. When the lowest rate in the marketplace 
auction for the hotel room in question is lower than the suggested deal that our algorithm places in the top 
position, we include that offer along with additional offers that users can access.

Our market opportunity 

As hotel discovery, evaluation and booking increasingly move online, travelers and advertisers face distinct 
challenges. 

Challenges for travelers 

With the digitalization of the hotel industry, there is an ever-increasing quantum of information available about 
hotels including amenities, style, reviews, location and pictures. Additionally, details on pricing and availability 
are continually updated in or near real-time. This information has empowered travelers, providing a level of 
insight that was previously unavailable. However, this information is often delivered via multiple, fragmented 
sources,  including  OTAs,  hotel  chains,  independent  hotels,  Internet  search  engines  and  other  review 
sites. Also,  many  websites,  including  those  that  aggregate  disparate  information,  are  slow,  confusing  to 
navigate, and may not display the best available hotel or pricing for travelers. Furthermore, many local OTAs 
and smaller hotels only display their information in the local language, which creates an additional layer of 
complexity for travelers looking to find the ideal hotel in a foreign destination. These developments can make 
booking a hotel a frustrating experience for travelers. 

Challenges for hotel advertisers 

Hotel advertisers operate in a competitive market with a broad range of participants, each having specific 
needs. OTAs need to drive high volumes of traffic to their websites to generate revenues, while hotel chains 
and independent hotels who operate high fixed cost models focus on ensuring their inventory is filled. Both 
OTAs and hotel advertisers aspire to reach a targeted audience of travelers with their marketing. 

Traditional  offline  advertising  media,  including  TV,  radio,  print  and  outdoor,  focus  on  reaching  a  broad 
audience and can be an expensive media for reaching the few travelers seeking hotels in a specific location 
on specific dates. 

There are challenges with online advertising as well. Many advertisers spend an increasing amount of their 
marketing budgets on online advertising where it is possible to economically reach a very broad audience 
through a website. However, the fragmentation of travelers online makes it difficult to scale cost effectively. 
Furthermore, OTAs, smaller hotel chains and hotels may not have the resources to develop sophisticated 
websites and as a result, provide a limited user experience in terms of attractiveness, comprehensiveness 
of information and ease of booking. Such websites often only publish information in local languages, limiting 
their reach to a local market. 

Benefits for our users

Global aggregation of real-time hotel supply

We aggregate hotel availability from a range of advertisers globally. This supply is continually updated, so 
users can view current availability from a broad range of advertisers. We believe travelers use our hotel 
search platform as their entry point for hotel research, confident that they receive comprehensive coverage 
of their options to book a hotel.

Increased price competition and reduced search costs 

Enhanced price competition results in the display of rooms with a broad range of pricing options available 
from our advertisers. 

47

Tailored hotel search function 

Our search function is designed to enable individual users to find their ideal hotel. We personalize results 
based on a user’s search terms, selected filters and other interactions with trivago’s platform. In addition, 
we aggregate and analyze multiple sources of information to build a profile for each individual hotel. trivago’s 
search algorithms, which are refined by millions of searches each day, create matches among the sets of 
information.

Deep content and easy-to-use information on hotels 

We obtain hotel information from many sources, such as travel booking sites, hotel websites, review sites, 
directly from hotels and internal resources. This information includes pictures, descriptions, reviews, ratings 
and  amenities.  We  synthesize  and  enrich  this  information.  For  example,  our  rating  score  distills  review 
information from multiple sources into a single easy-to-use score for the traveler.

Key benefits for advertisers 

Broad traveler reach 

We  offer  advertisers  a  highly  scalable  channel  of  travelers,  given  our  broad  presence  across  multiple 
geographies and languages. Additionally, for many travelers, we believe we are the entry point to their hotel 
search, enabling advertisers to engage with potential new customers. 

Delivery of transaction-ready referrals 

We provide advertisers with motivated travelers who have proactively expressed their specific intent via our 
search platform. Due to the breadth of hotel information we provide and our personalized matching algorithms, 
travelers referred by trivago often already have a comprehensive understanding of the hotel and its value 
proposition for them, which we believe makes them more likely to complete a booking on the advertiser’s 
site. 

Market-driven, referral-based pricing structure 

We believe our advertisers value the flexibility to control the pricing and volume of referrals they generate 
from our marketplace. Our CPC bidding model makes it easy for advertisers to evaluate the performance 
of their spend and influence their own return on investment. 

Improve advertisers’ competitiveness 

Hotel  advertisers  have  varying  levels  of  experience,  scale  and  resources  to  dedicate  to  their  marketing 
efforts. We provide our advertisers with advice, actionable data insights and advertiser tools to help them 
optimize their investment on our marketplace by improving the quality of available content about their hotel. 

Our strengths 

We believe that our competitive advantages are based on the following key strengths: 

Industry-leading product and user experience 

We believe that we provide the most effective and intuitive hotel search platform for travelers. We have 
invested in our product over many years and continue to spend significant time and resources on further 
refining our websites and apps to provide the best possible user experience. We regularly test and enhance 
multiple aspects of our websites and apps, believing that incremental advancements over time add up to 
improvements in overall user experience. This approach benefits both our users and advertisers by enabling 
more satisfying and effective engagement with our platform. 

48

Significant scale 

We have achieved significant scale, with more than 1.8 million hotels and other types of accommodation 
available on our platform as of December 31, 2017, supported by 55 localized versions of our websites and 
apps served in 33 languages. Additionally, we believe we work with almost all significant international, regional 
and local OTAs. Our business benefits from our engaged and often long-established relationships with local 
advertisers globally. In the year ended December 31, 2017, we had 727.1 million qualified referrals. Bringing 
together advertisers and users at this scale creates powerful network effects, improving the quality of the 
trivago experience for all parties. 

High brand recognition 

We have continuously invested in our brand over many years and have achieved strong brand recognition 
globally. Our brand drives traffic to our site by underpinning the connection travelers make between trivago 
and hotel search. 

Powerful data and analytics 

We  capture  large  amounts  of  data  across  our  platform,  including  traveler  data,  advertiser  data,  publicly 
available content and insights on how travelers and advertisers interact with our platform. As our business 
has grown, the volume of information we can analyze has also correspondingly increased. We take a data-
driven, testing-based approach, 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 this data enables us 
to continuously improve our platform. 

Our strategy

We create value to our users and our advertisers through the power of technology. We believe that the 
strength of our brand and our position as a first source of information for travelers drive customer demand, 
which when combined with our global scale and broad based accommodation supply gives us a unique 
position in the ongoing migration of travel from offline to online. Our primary focus are technology and product 
innovation, measures to increase lifetime value of our customers as well as our continued efforts in building 
our brand as part of our ongoing global expansion.

Product improvements

Our technology teams drive innovation to help users navigate through a vast number of hotel offerings to 
find the hotel that is ideal for them. In 2017, we continued to invest in our technology platform, rebuilding 
large parts of our back-end infrastructure. We believe that this effort will create a foundation for growth and 
scalability of new technology in the long term. We have released features improving the user interface, for 
example adding boundless maps to simplify hotel search based on location. Furthermore, we have recently 
taken steps to integrate alternative accommodation supply from HomeAway and other suppliers into our 
main search functionality. We have run tests relating to the integration in various countries, such as the 
United States, the United Kingdom and Germany. We plan to gradually roll out additional readily bookable 
alternative accommodation, such as vacation rentals or resorts, during the course of 2018.

We continue to focus our product innovations on increasing value delivered to our users by customizing our 
hotel search to our users’ interests beyond location and price comparisons.

Marketplace improvements and tools for advertisers

In late December 2016, we first introduced the relevance assessment, which is an adjustment to advertisers’ 
CPC bids on our marketplace’s auction process. During the fourth quarter of 2017, we upgraded our relevance 
assessment by introducing an automated calculation, new factors to approximate the user experience and 
general optimizations of the algorithm. We continue to focus on giving advertisers the flexibility to test and 
optimize their landing pages while promoting an experience on our website that we believe is optimal for 
our users. 

49

We remain focused on ensuring a healthy marketplace that connects our broad and deep supply of hotels 
and other accommodation with our user base. Apart from the steps we are taking to increase diversity on 
our marketplace described above, we aim to mitigate competitive disadvantages for smaller advertisers on 
our marketplace. We believe that by providing tools and services, especially for advertisers with less technical 
infrastructure  and  experience,  we  can  increase  competition  and  create  a  more  level  playing  field  for 
advertisers. 

Focus on lifetime value of the customer

We are implementing initiatives that are designed to focus more on the end-to-end booking value of our 
users and less on the revenue generated in session. We believe that these initiatives will help us increase 
booking conversion rates, RPQR and, ultimately, our financial performance over the long term. Some of 
these changes include:

•  Measures  aimed  at  optimizing  our  platforms  and  product,  as  described  above,  with  the  intention  of 
increasing booking conversion and user engagement on our site, thus reducing the number of click-outs 
required to ultimately make a booking; 

•  Our relevance assessment, which is an adjustment to advertisers’ CPC bids in our marketplace auction 
process  based  on  our  assessment  of  the  quality  of  users'  experience  after  leaving  our  website,  as 
described above; and 

•  Our  attribution  model,  which  is  our  model  for  allocating  our  performance  marketing  spend.  We 
continuously modify this attribution to reflect changes in how we determine whether revenue originated 
from a given marketing channel (or how revenue is “attributed” to that channel in our internal metrics). 
The attribution model informs decisions we make about how much we spend on different performance 
marketing channels. We continually change the model to focus on whether a user who comes to us from 
a performance marketing channel proceeds to book a hotel. 

Going forward, we plan to focus on changes to our platform, marketplace and advertising spend to optimize 
for traffic quality instead of volume. We aim to increase the value of our referrals by shortening the booking 
funnel.

Brand building

We continue to focus on building our trivago brand. In 2017, we ran and tested over 800 different TV spots 
globally. As a result, our aided brand awareness has reached over 75 percent in the U.S. market and more 
than 80 percent in the large European markets and in Australia. We still see potential for increasing brand 
awareness, especially in our faster-growing Rest of the World segment. 

We intend to be each traveler’s first source of hotel information by growing our engagement with travelers 
through continuous investment in both online and offline marketing to build our brand efficiently and drive 
strong  user  acquisition  and  retention.  We  plan  to  continue  enhancing  our  mobile  offerings  and  user 
engagement on mobile devices, thereby further increasing access for travelers to our services anytime and 
anywhere. We believe that investing in our brand combined with product innovations will help us further 
improve customer loyalty and retention. 

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; 

• 

Independent hotels; 

•  Providers of alternative accommodation, such as vacation rental or private apartments; and 

• 

Industry participants, including metasearch and content providers. 

50

We generate the large majority of our revenue from OTAs. Certain brands affiliated as of the date hereof 
with our majority shareholder, Expedia, including Brand Expedia, Hotels.com, Orbitz, Travelocity, Hotwire, 
Wotif and ebookers, in the aggregate, accounted for 39%, 36% and 36% of our total revenue for the years 
ended December 31, 2015, 2016 and 2017, respectively. Booking Holdings and its affiliated brands, 
Booking.com and, through 2015, Agoda, accounted for 27%, 43% and 44% of our total revenue for the 
years ended December 31, 2015, 2016 and 2017, respectively. 

Nearly all of our agreements with advertisers, including our agreements with our three largest advertisers, 
may be terminated at will or upon three to seven days’ prior notice 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 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. 

Competition for users 

We compete to attract users to our websites and apps to help them research and find hotels. Given our 
position at the top of the online hotel search funnel, many companies we compete with are also our customers. 

Our principal competitors for users include: 

•  Online metasearch and review websites, such as Kayak, Qunar, TripAdvisor and Google Hotel Ads; 

•  Search engines, such as Baidu, Bing, Google and Yahoo!; 

• 

Independent hotels and hotel chains, such as Accor, Hilton and Marriott; 

•  OTAs, such as Booking.com, Ctrip and Expedia; and 

•  Alternative accommodation providers, such as Airbnb and HomeAway. 

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 Baidu, Bing, Google and Yahoo!; 

•  Online metasearch and review websites, such as Kayak, Qunar, TripAdvisor and Google Hotel Ads; 

•  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, flexible working hours and flat organizational structure 
are key ingredients in our success. These have 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 act as 
entrepreneurs  in  their  areas  of  responsibility,  continuously  striving  for  innovation  and  improvement.  We 
encourage  our  employees  to  take  on  new  challenges  within  the  company  regularly  to  broaden  their 
perspective, accelerate their learning, ensure a high level of motivation and foster communication. 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 continually seek to understand and learn, 
take risks and innovate. We regard failure as an opportunity to learn and inform improved approaches going 
forward. 

Internally, we distill our values into six core qualities: 

•  Trust:    We want to build an environment in which mutual trust can develop that gives employees the 

confidence to discuss matters openly and act freely. 

•  Authenticity:    We aim to be authentic and appreciate constructive and straight feedback. 

•  Entrepreneurial passion:    We believe that entrepreneurial passion drives us forward to continuously try 

out new and improved ways of thinking and doing. 

•  Power of proof:    We believe that data, used correctly, can lead to empirical, proof-based decision making 

across the organization. 

•  Focus:    We are focused on reshaping the way travelers search for and compare hotels, while enabling 
hotel advertisers to grow their businesses by providing access to a broad audience of travelers via our 
websites and apps. We believe that multiple small, incremental improvements towards this goal add up 
to long-term success. 

•  Learning:    We never stand still and choose to remain open minded and inquisitive. We try new ideas 

and continue to challenge received wisdom.

In April 2017, we introduced our new leadership framework, which is another step we have taken that is 
intended to keep our company agile. Under the new framework, we have broken up the traditional reporting 
lines into three dimensions, allowing each employee to progress on the dimensions he or she is most excited 
about and suitable for. 

We have identified three core leadership roles: 

• 

• 

responsibility leads, who are responsible for the development of an operational area at trivago;

talent leads, who are responsible for individuals' professional and personal development at trivago; and 

•  knowledge leads, who are responsible for sharing expertise and developing knowledge within trivago on 

a specific topic. 

We envision that different individuals will often take on different leadership roles and will move into different 
roles as they learn what interests them and what role is most suitable for them. As our employees move into 
different roles within trivago, we intend for them to have one constant talent lead, who generally works on 
a different team.

We believe that moving employees into different leadership roles will help them use the expertise they have 
gained at trivago to challenge our thinking in different areas and to promote innovation. Our new leadership 
framework is intended to prevent us from forcing employees into pre-determined career development paths, 
which they did not actively choose to follow, and to create an environment where each employee can naturally 
come  across  opportunities  to  help  them  learn  and  grow.  By  doing  this,  we  plan  to  give  employees  the 
necessary freedom in their work in order for them to shape their own professional journeys while at trivago. 

52

Seasonality

We experience seasonal fluctuations in the demand for our services as a result of seasonal patterns in travel. 
For example, hotel 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 in the first and 
fourth quarter of the year as we typically expect to advertise less in the periods outside of high travel seasons, 
although the expected increase in return on advertising spend was less pronounced in the fourth quarter of 
2017. 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 spending. The continued 
growth 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, Room5, Youzhan and 
our trivago logo. These trademarks are registered in various jurisdictions. 

Government regulation 

trivago provides data and information to its users and advertisers 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 European Union (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 Internet products and services, the quality 
of products and services as well as the liability for third-party activities. Moreover, the applicability to the 
Internet  of  existing  laws  governing  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. As of May 25, 2018, a new EU data 
protection regime (EU’s General Data Protection Regulation 2016/679 or GDPR) will become applicable 
that provides for a number of changes to the existing EU data protection regime. The GDPR applies to any 
company established in the EU as well as to those outside the EU if they collect and use personal data in 
connection with the offering of goods or services to individuals in the EU or the monitoring of their behavior 
(for example, trip booking services).  The GDPR enhances data protection obligations for processors and 
controllers of personal data, including, for example, expanded disclosures about how personal information 
is to be used, limitations on retention of information, mandatory data breach notification requirements and 
onerous new obligations on services providers. Non-compliance with the GDPR can trigger steep fines of 
up to €20  million or 4% of total worldwide annual turnover, whichever is higher. We may incur substantial 
expense in complying with the new obligations to be imposed by the GDPR and we may be required to make 
significant changes in our business operations and product and services development, all of which may 
adversely affect our revenues and our business overall. 

53

In addition, EU laws regulate transfers of EU personal data to third countries, such as the United States, 
that have not been found to provide adequate protection to such personal data. A number of our service 
providers  and  hotels  operate  in  such  jurisdictions.  There  are  recent  regulatory  concerns  about  certain 
measures  that  can  be  used  to  validate  such  data  export,  as  well  as  litigation  challenging  some  of  the 
mechanisms for adequate data transfer (i.e., the standard contractual clauses). We could be impacted by 
changes in law as a result of the current challenges to these mechanisms by regulators and in the European 
courts which may lead to governmental enforcement actions, litigation, fines and penalties or adverse publicity 
which could have an adverse effect on our reputation and business. 

Many governmental authorities in the markets in which we operate are also considering alternative legislative 
and  regulatory  proposals  that  would  increase  regulation  on  Internet  display,  disclosure  and  advertising 
activities. It is impossible to predict whether 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 at five different locations in Germany, the United States, Hong Kong and China, while 
also selectively leveraging cloud hosted services, which we believe offers us secure and scalable storage 
at limited incremental expense. While much of the data we receive and capture is not sensitive, our data 
centers  are  compliant  with  the  highest  security  standards.  It is  our  policy  to  store  separately  the  limited 
amount of sensitive data that we do capture. Where required, our data centers are PCI compliant. We have 
designed our websites, apps and infrastructure to be able to support high volume demand. 

Software 

We develop our own software through our teams based in Germany, the Netherlands and Spain, employing 
a rigorous iterative approach. This includes the proprietary algorithm underlying our search function, internal 
management tools, data analytics and advertiser tools.

C. Organizational structure

trivago N.V. historically acted as a holding company of trivago GmbH, the historical operating company of 
the trivago group. As described in more detail below under "—Post-IPO merger", the merger of trivago GmbH 
into and with trivago N.V. became effective on September 7, 2017. In this annual report, unless the context 
otherwise requires, the terms “we,” “us,” “our,” “trivago” and the “company” refer to trivago GmbH, travel B.V. 
and trivago N.V., and their respective consolidated subsidiaries, as applicable. 

Pre-IPO corporate reorganization 

On December 21, 2016, trivago N.V. completed its IPO. In connection with the IPO, we underwent a pre-
IPO corporate reorganization, and trivago N.V. became the parent holding company of trivago GmbH. Prior 
to  the  pre-IPO  corporate  reorganization,  Expedia  owned  63.5%  and  the  Founders  owned  36.5%,  in 
aggregate, of the voting power in trivago GmbH. On December 16, 2016, Expedia contributed pursuant to 
the pre-IPO corporate reorganization all of its units in trivago GmbH to travel B.V. in a capital increase in 
exchange for newly issued Class B shares of travel B.V. In connection with the change of legal form of travel 
B.V. into trivago N.V., such shares were converted into Class B shares of trivago N.V. 

The Founders contributed 1,081 units, including units contributed to satisfy the underwriters’ exercise of the 
over-allotment option, of trivago GmbH, representing 7.7% of their aggregate shareholding in trivago GmbH, 
to travel B.V. in a capital increase in exchange for newly issued Class A shares of travel B.V., which were 
converted into Class A shares of trivago N.V. and subsequently sold as ADSs in the IPO. 

Post-IPO merger 

Following  our  IPO,  we  requested  binding  tax  rulings  from  the  German  tax  authorities  regarding  the  tax 
neutrality to trivago GmbH, trivago N.V. and the Founders of our plan to merge trivago GmbH into and with 
trivago N.V., which we refer to as the post-IPO merger. Based on the facts presented in the requests for the 
rulings, the tax rulings confirmed the tax neutrality of the post-IPO merger for trivago GmbH, trivago N.V. 
and the Founders under German tax law in all material respects. Following receipt of such tax rulings, we 
consummated the post-IPO merger, which became effective on September 7, 2017. Pursuant to the post-
IPO merger, the Founders exchanged all of their units in trivago GmbH remaining after the pre-IPO corporate 
reorganization for Class B shares of trivago N.V. As of December 31, 2017 and after all trivago GmbH units 
were exchanged for Class B shares of trivago N.V., the Founders held 34.3% of the voting power in trivago 
N.V., and Expedia held 64.7% of the voting power in trivago N.V.

Current organizational structure

The following chart depicts our corporate structure and percentages of economic interest as of the date 
hereof based on the number of shares outstanding as of December 31, 2017:

trivago N.V. is the direct or indirect holding company of our subsidiaries.  As of December 31, 2017, we do 
not own, directly or indirectly, any subsidiaries that we consider to be "significant". We used the three-part 
test set out in Section 1-02 (w) of Regulation S-X under the Exchange Act to determine significance. We do 
not have any other subsidiaries we believe are material based on other, less quantifiable, factors. 

D. Property, plant and equipment

Our corporate headquarters are located in Düsseldorf, Germany where we lease office space of 17,761 
square  meters,  in  the  aggregate,  under  separate  lease  agreements  expiring  between  June  2018  and 
December 2019. 

On July 23, 2015, we entered into a lease agreement for 26,107 square meters of office space at another 
location in Düsseldorf, Germany for a ten-year fixed term commencing upon finalization of the construction 
of the facilities. We intend to relocate our corporate headquarters to such facilities in 2018 when construction 
is expected to be completed.

You should read the following discussion and analysis of our financial condition and results of operations in 
conjunction  with  “Item  3  A.  Key  information—Selected  financial  data”  of  this  annual  report  and  our 
consolidated financial statements and related notes appearing elsewhere in this annual report. In addition 
to  historical  information,  this  discussion  contains  forward-looking  statements  based  on  our  current 
expectations that involve risks, uncertainties and assumptions. Our actual results may differ materially from 
those anticipated in these forward-looking statements as a result of various factors, including those set forth 
in the “Risk factors” and “Special note regarding forward-looking statements” sections and elsewhere in this 
annual report. 

A. Operating results

Overview 

Our total revenue for the years ended December 31, 2015, 2016 and 2017 was € 493.1 million, € 754.2 million
and € 1,035.4 million, respectively, representing an increase of 53% from 2015 to 2016 and 37% from 2016
to 2017. Our Referral Revenue for the years ended December 31, 2015, 2016 and 2017 was € 490.2 million, 
€ 745.8 million and € 1,020.3 million, respectively. Referral Revenue grew by 37% year-over-year from 2016 
to 2017. Our Americas and Rest of World segments were the main contributors to that growth, with year-
over-year  increases  of  37%  and  84%,  respectively,  from  2016  to  2017,  while  Referral  Revenue  in  our 
Developed Europe segment also grew by 22% year over year. 

Our net losses for the years ended December 31, 2015, 2016 and 2017 were € 39.4 million, € 51.4 million
and € 13.0 million, respectively, increasing by 30% from 2015 to 2016 and decreasing by 75% from 2016 to 
2017.

Adjusted EBITDA for the years ended December 31, 2015, 2016 and 2017 amounted to €(1.1)  million, €28.2 
million and €6.7  million respectively. This implies an Adjusted EBITDA margin (calculated as Adjusted EBITDA 
divided by total revenue) of (0.2)%, 3.7% and 0.6%, respectively. 

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 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 earn subscription fees for certain services we provide to advertisers, such as Hotel Manager Pro, 
although such subscription fees do not represent a significant portion of our revenue. 

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 on a cost-per-click, or 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 hotel 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 

58

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 had 334.6 million, 535.3 million and 727.1 million Qualified Referrals for the years ended December 31,
2015, 2016 and 2017, respectively, representing annual growth rates of 60.0% and 35.8% in 2016 and 2017, 
respectively.

We believe the primary factors that drive our Qualified Referral development are the number of visits to our 
websites and apps, the booking intent of our visitors, the number of available hotels on our hotel 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. Ultimately, we aim to increase the number of Qualified Referrals we 
generate  by  focusing  on  making  incremental  improvements  to  each  of  these  parameters.  In  addition  to 
continuously seeking to expand our number of relationships with hotel advertisers, we partner with such 
hotels to improve content, and we constantly test and improve the features of our websites and apps to 
improve the user experience, including our interface, site usability and personalization for each visitor.

indicated:

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

RPQR is determined by the CPC bids our advertisers submit on our marketplace as the CPC bids submitted 
by our advertisers 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 our advertisers’ websites, or booking conversion, and the amount our advertisers obtain from Qualified 
Referrals as a result of hotels booked on their sites, or booking value, and the degree to which advertisers 
are willing to share with us the overall estimated booking revenues generated by our advertisers from our 
referrals, or revenue share, which we also refer to as "commercialization". We estimate booking conversion 
and booking value from data voluntarily provided to us by certain advertisers to better understand the drivers 

59

in  our  marketplace,  and  in  particular,  to  gain  insight  into  how  our  advertisers  manage  their  advertising 
campaigns. Generally, the higher the potential booking value 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. 
This means that the levels of advertisers' CPC bids reflect their view of the likelihood that each click on an 
offer will result in a booking by a user. Reflecting these dynamics, 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, even though we 
invoice the majority of our advertisers in euro and have relatively little direct foreign currency translation with 
respect to our revenue.

RPQR is a key financial metric that describes 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. For the years ended December 
31, 2015, 2016 and 2017, RPQR was € 1.46, € 1.39 and € 1.40, respectively.

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. Our ROAS was 113%, 120% and 115% for the years 
ended December 31, 2015, 2016 and 2017, respectively. Our ROAS in the Americas, Developed Europe 
and the Rest of World was 102%, 133% and 87% for the year ended December 31, 2015, respectively, as 
compared to 118%, 136% and 90% for the year ended December 31, 2016, respectively, and 116%, 131%
and 92% for the year ended December 31, 2017, respectively. We believe the development of our ROAS 
among the reportable segments is primarily related to the different stages of development of our markets. 
For example, in Developed Europe, where we have operated the longest on average, we have historically 
experienced the highest average ROAS. Our ROAS in the Rest of World segment, where we have the lowest 
average ROAS, is also impacted significantly by the number of markets in the segment, including markets 
that we have recently entered and thus require significant advertising spend to reach scale. Over time, as 
our markets continue to develop, we believe that we will experience further increases in the efficiency of our 
advertising spend and thus improvements in our average ROAS. Given that advertising expenses account 
for the significant majority of our operating expenses, we believe this will have a direct impact on our operating 
margins and Adjusted EBITDA. 

Historically, we believe that our advertising has been successful in generating additional revenue. We invest 
in many kinds of marketing channels, such as TV, out-of-home advertising, radio, search engine marketing, 
display and affiliate marketing, email marketing, social media, online video, mobile app marketing and content 
marketing.

Recent trends in our business

The following trends have contributed to the results of our consolidated operations, and we anticipate that 
they will continue to impact our future results: 

Marketplace dynamics and increased volatility 

Changes in marketplace dynamics, particularly as a result of changing bidding strategies and testing by our 
advertisers, have contributed to the increased volatility of our financial results and to the substantial slowdown 
in revenue growth that we experienced in the second half of 2017. In the first half of 2017, we benefited from 
the introduction of our relevance assessment, which is an adjustment to advertisers’ CPC bids based on our 
assessment  of  the  quality  of  users’  experience  after  leaving  our  website.  In  the  first  half  of  2017,  some 
advertisers  compensated  for  their  lower  relevance  assessment  by  submitting  higher  CPC  bids.  This 
development positively impacted Referral Revenue and increased levels of commercialization of our platform. 
Starting in the final weeks of June 2017, some of our significant advertisers optimized their websites and 
bidding strategies in response to the introduction of the relevance assessment. As a result, advertisers were 
able to lower their CPC bids starting in the third quarter of 2017, which resulted in an algorithm-driven pull 
back in our performance marketing advertising spend in the third quarter of 2017 and was accompanied by 
a deceleration of our brand marketing expenditure growth. The second half of 2017 was also negatively 
impacted by lower levels of commercialization and increased volatility on our marketplace due to significant 
testing activities by our largest advertisers. Some of our largest advertisers also conducted significant testing 
activities on our marketplace at elevated levels as they looked to optimize their own advertising spend on 
our platform and those of our competitors. Some advertisers have withdrawn from our marketplace for periods 
of time in certain geographic markets, including in some of our key markets, and have also deactivated some 
of their inventory, most frequently inventory that they alone advertised or was inactive. During the fourth 
quarter of 2017, we also upgraded our relevance assessment, by introducing an automated calculation, new 
factors to approximate the user experience and general optimizations of the algorithm. Some of the testing 
referred to above included advertisers’ testing of their landing pages in response to the relevance assessment, 
which, together with changing advertiser bidding strategies, significantly impacted CPC bids and levels of 
commercialization  on  our  marketplace. As  volatility  increased  on  our  marketplace,  advertisers  had  less 
certainty about marketplace dynamics and less clarity surrounding CPC bids to make informed decisions 
about their bidding and strategy, which also impacted marketplace dynamics during affected periods. 

Changes in our levels of commercialization

Changes in commercialization are reflected in our Referral Revenue and RPQR levels as our advertisers 
adjust the CPC bids they submit on our marketplace. 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 Booking Holdings and Expedia can permit them 
to obtain the same or increased levels of referrals, customers, bookings or revenue and profit at lower cost. 
During 2017, we observed a number of trends that impacted levels of revenue share and commercialization 
of our marketplace:

•  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;

•  The fees advertisers are willing to pay based on how they manage their advertising costs and their 

targeted return on investment; and

•  Our advertisers’ response to changes made to our marketplace, such as the relevance assessment.

Advertising expense 

For the years ended December 31, 2015, 2016 and 2017, we spent € 432.2 million, € 623.5 million and € 884.7 
million on advertising, respectively, representing 87.6%, 82.7% and 85.4% of our total revenue for such 
periods. We believe that increasing brand awareness creates self-reinforcing value by resulting in a greater 
number of visits to our platform and referrals to our advertisers that encourage more OTAs and hotels to 
advertise their inventory in our search results, which in turn makes our services more useful to users, further 
increasing the number of visits to our websites and apps and referrals to our advertisers. We believe that 
these  investments  contributed  significantly  to  our  revenue  growth  historically,  although  we  expect 
deceleration in revenue growth rates in our more mature markets as our share in those markets increases 
and further advances in brand awareness become increasingly difficult and expensive to achieve. We already 
experienced a deceleration in revenue growth in these markets and a significant slowdown in our advertising 
spend growth, as described above, contributed to a decline in Referral Revenue in Developed Europe in the 
fourth quarter of 2017. Increasing brand awareness and usage of our platform are important parts of strategy 
as we plan to return to growth in the second half of 2018, and at this time we expect to continue to invest in 
marketing. 

Rapid changes in Referral Revenue resulting from dynamics on our marketplace and changes in advertiser 
behavior can occur with little or no notice to us, and have resulted in our not having enough time to pull back 
our advertising spend, particularly on television, quickly enough to respond to the speed of the change in 
revenue levels. This was the case in the third quarter of 2017, when we were initially unable to pull back 
planned TV advertising spend quickly enough to respond to the speed of the RPQR slowdown. In addition, 
rapid slowdowns in Referral Revenue, such as that in the third quarter of 2017, can cause the algorithms 
that we use to allocate our performance marketing spend to pull back performance marketing spend more 
quickly  than  in  an  environment  with  lower  volatility. As  we  spent  the  great  majority  of  our  revenue  on 
advertising, our inability to pull back advertising negatively impacted our operating results in 2017. 

Measures designed to maximize the lifetime value of the user 

We are implementing initiatives that are designed to focus less on revenue generated in each user session 
and more on the end-to-end booking value of our users. Some of these measures include: 

•  Measures aimed at optimizing our platforms and product, with the intention of increasing user retention 
and booking conversion, while reducing the number of click-outs required to ultimately make a booking. 
These are relatively small, incremental changes to our product that we believe, when considered together, 
will result in improvements to our product and platform; and

•  Our  attribution  model,  which  is  our  model  for  allocating  our  performance  marketing  spend.  We 
continuously modify this model to reflect changes in how we determine whether revenue originated from 
a given marketing channel (or how revenue is “attributed” to that channel in our internal metrics) and 
that informs decisions we make about how much we spend on different performance marketing channels. 
The new attribution model focuses on whether a user who comes to us from a performance marketing 
channel books a hotel.

Since we make these changes by optimizing for traffic quality instead of volume, these changes have tended 
to have a negative impact on Qualified Referrals, but have contributed to positive effects in RPQR. Following 
the roll-out of the new attribution model in our Display, Email and Affiliate Advertising channel in the third 
quarter of 2017 and the implementation of measures aimed at optimizing our platform, we experienced higher 
volatility and a slowdown in Qualified Referral growth. We expect similar effects in the near-term resulting 
from the roll-out of the new attribution model in our Search Engine Marketing channel and as we implement 
additional  measures  to  optimize  our  platform.  Going  forward,  we  may  make  additional  changes  to  our 
marketplace and platform that may contribute to further volatility in our results, but we believe will help us 
increase booking conversion rates, RPQR and, ultimately, our financial performance over the long term.

Global penetration 

Our Referral Revenue from the Americas, Developed Europe and the Rest of World were 38.0%, 46.3% and 
14.7% of our total revenue, respectively, for the year ended December 31, 2016 and were 37.8%, 41.0% 
and 19.7% of our total revenue, respectively, for the year ended December 31, 2017. We believe the relative 
growth in Referral Revenue across our reportable segments is primarily related to the different stages of 
development of our markets. We generate the most Referral Revenue in Developed Europe, our segment 
that includes the markets where we have operated the longest and where we have the highest level of brand 
awareness but relatively moderate growth. We typically expect to have higher growth rates in newer markets, 
and as a result, expect our Referral Revenue in the Americas and the Rest of World to increase at a faster 
rate than Referral Revenue in Developed Europe. We continue to improve the localization of our websites 
and apps for each market in an effort to augment the user experience and to grow our user base globally. 
We invest heavily in marketing campaigns across our markets. 

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, 2017, 
our revenue share from mobile websites and apps exceeded 60%.

Visitors to our hotel search platform via mobile phone and tablet 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 hotel 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 bidding 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. 

We believe mobile websites and apps will continue to gain popularity, and we expect to continue to commit 
resources to improve the features, functionality and conversion rates of our mobile websites and apps. 

Advertiser diversification and direct relationships with hotels 

We generate most of our revenue from a limited number of OTAs. Certain brands affiliated as of the date 
hereof with our majority shareholder, Expedia, including Brand Expedia, Hotels.com, Orbitz, Travelocity, 
Hotwire, Wotif and ebookers, in the aggregate, accounted for 39%, 36% and 36% of our total revenue for 
the years ended December 31, 2015, 2016 and 2017, respectively. Booking Holdings and its affiliated brands, 
Booking.com  and Agoda,  accounted  for  27%,  43%  and  44%  of  our  total  revenue  for  the  years  ended 
December 31, 2015, 2016 and 2017, respectively. We believe that our business success in the long term 
will be enhanced by diversification among our advertisers, in particular by means of expanding our direct 
relationships  with  independent  hotels,  hotel  chains  and  providers  of  alternative  accommodation  and 
continuing to act as a platform that enables travelers to compare hotel rooms that are offered by smaller and 
local OTAs or independent hotels or by the leading international brands. 

64

We have recently taken steps to increase advertiser diversity on our marketplace, including increasing the 
representation of individual hotels into our inventory, making investments in our advertisement relations team 
and  integrating  HomeAway’s  vacation  rental  inventory  onto  our  hotel  search  platform,  with  the  aim  of 
integrating additional inventory of alternative accommodation going forward. Advertiser diversification allows 
us to improve the user experience by expanding the depth of our hotel offerings to facilitate price transparency 
as well as to improve the content quality, availability and usability of our advertisers’ offers, thereby increasing 
the value our users derive from our websites and apps. For example, some independent hotels and smaller 
hotel chains rely exclusively on their own websites and/or an OTA to distribute their offerings. Our engagement 
with such advertisers permits us to display an offer on behalf of that advertiser directly, making the offer 
accessible to our users, or increasing the number of offers if an accommodation was previously only available 
through an OTA. Direct engagement also permits an advertiser to have more control of the content and 
placement of its offer, since we are able to offer tools and assistance to optimize content and offer strategy 
on our marketplace. In addition, we recently began offering a booking engine product for our direct hotel 
relationships in order to make it easier for our users to book an accommodation online for an advertiser that 
did not otherwise have an online booking engine available.

We believe advertiser diversification could mitigate some of the risks we face with respect to consolidation 
within the travel content marketplace, as consolidation could over time reduce the number of offers we have 
available on our platform for each hotel, which could cause our services to become less valuable to users. 
Correspondingly, with fewer bids for offers from a consolidated group of advertisers, RPQR could decrease. 
We believe that as a result of the number of marketplace participants and the competition among various 
brands within consolidated OTAs, there has historically been sufficient liquidity on our marketplace to sustain 
competitive bid levels in our most relevant markets, such that if the top bidder leaves the platform, the next 
highest bidder moves into position to partially sustain our revenue. We have observed this to some extent 
as  some  of  our  largest  advertisers  have  withdrawn  from  our  marketplace  for  periods  of  time  in  certain 
geographic markets, although this testing activity had a significant negative impact on our financial results 
in the fourth quarter of 2017. In less liquid geographic markets, our initiative to connect hotels directly to our 
platform may mitigate, at least in small part, a potential decrease in OTA marketplace participants. As of 
December 31, 2017, we had direct relationships with over 400,000 hotels, representing over 22% of the total 
number of hotels advertised on trivago.

Total revenue for the year ended December 31, 2017 was € 1,035.4 million, representing an increase of 
€ 281.2 million, or 37.3%, compared to the year ended December 31, 2016. Revenue from related party for 
the  year  ended  December 31,  2017  increased  by  € 99.4  million,  or  37.0%,  compared  to  the  year  ended 
December 31, 2016, while revenue from third parties increased by 37.4% for the same period. The increase 
of  revenue  from  third  parties  is  due  to  the  positive  revenue  effect  in  the  first  half  of  2017  following  the 
introduction  of  our  relevance  assessment  as  some  third-party  advertisers  compensated  for  their  lower 
relevance  assessment  by  submitting  higher  CPC  bids  versus  the  Expedia  group  of  companies  on  our 
marketplace. In the second half of 2017, advertisers were able to lower their CPC bids as these advertisers 
responded to the introduction of the relevance assessment, as described above. 

Total revenue for the year ended December 31, 2016 was € 754.2 million, representing an increase of € 261.1 
million, or 53.0%, compared to the year ended December 31, 2015. Revenue from related parties for the 
year ended December 31, 2016 increased by € 74.0 million, or 38.1%, compared to 2015, while revenue 
from third parties increased by 62.6% for the same period. The increase in revenue from related parties is 
due to higher bidding for advertising on our marketplace in 2016 compared to 2015 by the Expedia group 
of companies, in the aggregate. 

Our total revenue in the year ended December 31, 2017 consisted of Referral Revenue of € 1,020.3 million
and other revenue of € 15.0 million. Our total revenue in the year ended December 31, 2016 consisted of 
Referral Revenue of € 745.8 million and other revenue of € 8.3 million. Our total revenue in the year ended 
December 31, 2015 consisted of Referral Revenue of € 490.2 million and other revenue of € 2.8 million. 

67

Referral Revenue in the year ended December 31, 2017 increased by € 274.5 million, or 36.8%, compared 
to  2016. The  number  of  Qualified  Referrals  increased  by  35.8%  in  the  year  ended  December 31,  2017
compared to 2016. During the same period, RPQR increased by 0.7%. The growth in Referral Revenue was 
driven by strong advertising spend and the positive Referral Revenue effects during the first half of 2017
following the introduction of our relevance assessment as described above. We reinvested additional Referral 
Revenue from the relevance assessment in advertising, which also had a positive effect on Referral Revenue 
during the first half of 2017. In the second half of 2017, we experienced a significant slowdown in Referral 
Revenue growth as some significant advertisers responded to the introduction of the relevance assessment 
as described above. This included an algorithm-driven pull back in our performance marketing advertising 
spend and a deceleration of our brand marketing expenditure growth. The second half of 2017 was also 
negatively impacted by lower levels of commercialization and increased volatility on our marketplace due to 
significant testing activities by our largest advertisers.

The increase in Qualified Referrals in the year ended December 31, 2017 was due to the increased awareness 
of our brand and continued strong TV advertising spend, as well as an increase in performance marketing 
spend in the first half of 2017. The significant slow-down in Qualified Referral growth rates in the second 
half of 2017 compared to the same period in 2016 was driven by a deceleration of our advertising spend 
growth and the impact of the new attribution model and ongoing product optimization as described above.

RPQR was positively impacted in the first half of 2017 by the introduction of the relevance assessment in 
our marketplace algorithm, which was partially offset in the second half of 2017 by the negative revenue 
effects described above relating to our advertisers’ response to the introduction of the relevance assessment 
as well as lower levels of commercialization and increased advertiser testing activities. The second half of 
2017 was also negatively impacted by the relative weakening of the U.S. dollar and certain currencies in the 
Asia Pacific region but was positively impacted by effects we observed from the continued roll-out of the 
new attribution model and the implementation of measures aimed at optimizing our platforms, which we 
believe contributed to increased levels of booking conversion. RPQR in 2017 was also negatively impacted 
by the increased weighting of RPQR in our Rest of World segment.

Referral Revenue in the year ended December 31, 2016 increased by € 255.6 million, or 52.1%, compared 
to 2015. This growth was primarily due to an increase by 60.0% in the number of Qualified Referrals in the 
year ended December 31, 2016 compared to 2015. During the same period, RPQR decreased by 4.8%.

Referral Revenue in the Americas in the year ended December 31, 2017 increased by € 105.3 million, or 
36.8%, compared to the year ended December 31, 2016. This growth was primarily due to an increase by 
36.4% in the number of Qualified Referrals in the year ended December 31, 2017 compared to the year 
ended December 31, 2016. The increase in Referral Revenue was primarily driven by the positive impact 
of the relevance assessment in the first half of 2017 and our advertisers' response to the introduction of the 
relevance assessment as well as lower levels of commercialization and increased advertiser testing activities 
described above. We also faced significant headwinds towards the end of 2017 as a result of the relative 
weakening of the U.S. dollar against the euro.

During the same period, RPQR in the Americas increased by € 0.01, or 0.5%, compared to 2016. The increase 
in RPR for the period of 8.6% was almost completely offset by a decline in the click-out rate of 7.7%. The 
decline in the click-out rate reflected the impacts of platform optimization measures and the new attribution 
model, which have led to fewer referrals per Qualified Referral. In addition, click-out rates tend to decrease

platform. 

Referral Revenue in the Americas in the year ended December 31, 2016 increased by € 114.5 million, or 
66.6%, compared to the year ended December 31, 2015. This growth was primarily due to an increase by 
71.2% in the number of qualified referrals in the year ended December 31, 2016 compared to the year ended 
December 31, 2015. This growth was significantly driven by growth in the United States, where we focused 
our marketing activities to further develop our visibility with advertisers and travelers. During the same period, 
RPQR in the Americas decreased by € 0.05, or 2.5%, compared to 2015 even though RPR for the period 
increased by 7.7%. This was due to a decrease in the click-out rate of the period of 9.7%, a consequence 
of our product optimization, which typically leads to fewer referrals per Qualified Referral, and an increasing 
share of Qualified Referrals from maturing markets in Latin America with a lower RPQR lowering the segment 
average.

Referral Revenue for Developed Europe in the year ended December 31, 2017 increased by € 76.1 million, 
or 21.8%, compared to the year ended December 31, 2016. This growth was primarily due to an increase 
of 15.7% in the number of Qualified Referrals in the year ended December 31, 2017 compared to 2016. The 
increase in Referral Revenue was driven by the positive impacts of the relevance assessment in the first 
half of 2017. In the second half of 2017, we experienced a significant slowdown in Referral Revenue growth 
as  a  result  of  the  negative  revenue  effects  described  above  relating  to  our  advertisers’  response  to  the 
introduction  of  the  relevance  assessment.  In  Developed  Europe,  the  impact  of  lower  levels  of 
commercialization  and  testing  activities  of  our  largest  advertisers  in  the  second  half  of  2017  was  more 
pronounced, negatively affecting Referral Revenue  in that period.  In 2017, RPQR in Developed  Europe 
increased by € 0.07, or 5.1%, even though RPR increased by 19.1% for the period, which was partly offset 
by a reduction in the click-out rate for the period by 11.1%, reflecting the impacts of platform optimization 
measures and the new attribution model, which have led to fewer referrals per Qualified Referral.

Referral Revenue for Developed Europe in the year ended December 31, 2016 increased by € 89.3 million, 
or 34.4%, compared to the year ended December 31, 2015. This growth was primarily due to an increase 
by 39.0% in the number of Qualified Referrals in the year ended December 31, 2016 compared to 2015. 
During  the  same  period,  RPQR  in  Developed  Europe  decreased  by  € 0.04,  or  2.8%,  even  though  RPR 
increased by 6.8% for the period due to a reduction in the click-out rate for the period of 11.1%.

Referral Revenue for the Rest of World in the year ended December 31, 2017 increased by € 93.1 million, 
or 84.3%, compared to the year ended December 31, 2016. This growth was primarily due to the 74.6%
increase in the number of Qualified Referrals in the year ended December 31, 2017 compared to the year 
ended December 31, 2016. The increase in Referral Revenue was primarily driven by the positive impacts 
of the relevance assessment in the first half of 2017. In the second half of 2017, we experienced a significant 
slowdown in Referral Revenue growth as a result of the negative revenue effects described above relating 
to  our  advertisers’  response  to  the  introduction  of  the  relevance  assessment  and  lower  levels  of 
commercialization and increased advertiser testing activities. We also faced significant headwinds towards 
the end of 2017 as a result of the relative weakening of the U.S. dollar against certain currencies in the Asia 
Pacific region. During the same period, RPQR in Rest of World increased by € 0.04, or 4.7% even though 
RPR even increased by 10.3% for the period due to a reduction in the click-out rate for the period of 5.8%. 
The decline in the click-out rate reflected the impacts of platform optimization measures and the attribution 
model, which have led to fewer referrals per Qualified Referral.

Referral Revenue for Rest of World in the year ended December 31, 2016 increased by € 51.8 million, or 
88.2%, compared to the year ended December 31, 2015. This growth was primarily due to an increase by 
104.9% in the number of Qualified Referrals in the year ended December 31, 2016 compared to 2015. During 
the same period, RPQR in Rest of World decreased by € 0.07, or 7.6%, even though RPR increased by 3.6% 
for the period due to a reduction in the click-out rate for the period by 11.0%. Increased marketing in newer 
regions in our Rest of World segment, particularly in Japan, had a significant impact on our Referral Revenue 
growth in the segment for the year ended December 31, 2016 as compared to the year ended December 31, 
2015.

Cost of Revenue and Expenses 

Cost of revenue, including related party 

Our cost of revenue consists primarily of our data center costs, personnel-related expenses and share-based 
compensation for our data center operations staff and our customer service team. Cost of revenue, including 
from related party, was € 2.9 million, € 4.3 million and € 5.9 million for the years ended December 31, 2015, 
2016 and 2017, respectively. 

Cost of revenue for the year ended December 31, 2017 increased by € 1.6 million, or 37.2%, compared to 
the  year  ended  December 31,  2016  mainly  due  to  an  increase  in  maintenance  fees  for  servers  and 
depreciation of €1.1  million and €0.6  million, respectively, as we continued to extend and upgrade our data 
center operations and continue to make investments to reach scale. Our personnel-related costs increased 
by €0.6  million due to an increase in headcount from 26 employees as of December 31, 2016 to 60 employees 
as of December 31, 2017 and were offset by a € 0.6 million decrease in share-based compensation due to 
fluctuations in the fair value accounting treatment of awards which were classified as liability awards in the 
prior periods. See Note 10—Share based awards and other equity instruments in the notes to our consolidated 
financial statements. 

Cost of revenue for the year ended December 31, 2016 increased by € 1.4 million, or 48.3%, compared to 
the year ended December 31, 2015 due to a €1.2  million increase in depreciation and maintenance of servers 
and a €0.2  million increase in personnel-related costs. The increase in personnel-related costs was primarily 
driven by increases in share-based compensation expense of €0.5  million due to fluctuations in the fair value 
accounting treatment of liability classified awards granted in prior periods. See Note 10—Share based awards 
and other equity instruments in the notes to our consolidated financial statements. The €0.5  million increase 
was partially offset by a €0.3  million decrease of other personnel-related costs due to a decrease in headcount 
from 39 employees as of December 31, 2015 to 26 employees as of December 31, 2016 due to reallocation 
of certain IT employees to general and administrative. 

Selling and marketing 

Selling  and  marketing  consists  of  all  selling  and  marketing  related  costs  and  is  divided  into  advertising 
expense and other selling and marketing expenses, including share-based compensation expense. 

Advertising expense consists of fees that we pay for our various marketing channels like TV, out-of-home 
advertising,  radio,  search  engine  marketing,  search  engine  optimization,  display  and  affiliate  marketing, 
email marketing, online video, app marketing and content marketing. 

Other selling and marketing expenses include research costs, production costs for our TV spots and other 
marketing material, as well as personnel-related expenses and share-based compensation for our marketing, 
sales, hotel relations and country development teams.

spend across all regions. Advertising spend was at elevated levels in the first half of 2017 as we reinvested 
additional Referral Revenue from the introduction of the relevance assessment into our marketing activities. 
As most of our advertisers changed their landing pages in response to the introduction of the relevance 
assessment at the end of the second quarter of 2017, we reduced our advertising spend in the second half 
of 2017 to account for the reduction in our commercialization; however we were initially unable to pull back 
planned TV advertising spend quickly enough to respond to the speed of the RPQR slowdown in the second 
half of 2017, reflecting our inability to reduce planned TV advertising spend due to commitments in some 
markets. Selling and marketing expenses for the year ended December 31, 2016 increased by €21 1.9 million, 
or 45.9%, compared to the year ended December 31, 2015, primarily driven by an increase in marketing 
activities across all markets. 

Other selling and marketing expenses for the year ended December 31, 2017 increased by € 19.9 million, 
or 51.3%, compared to the year ended December 31, 2016 primarily by increases in production costs for 
TV advertisements, notably in Rest of World and Developed Europe, higher personnel costs and increased 
spending on marketing material. We also increased our headcount from 521 employees as of December 31, 
2016 to 606 employees as of December 31, 2017, mainly related to employees hired for hotel sales teams 
to increase the acquisition of new hotels on our marketplace and expand our hotel services sales. This led 
to an increase in personnel-related expense of €6.1  million for the year ended December 31, 2017. Other 
selling and marketing expenses for the year ended December 31, 2016 increased by € 13.1 million, or 51.0%, 
compared to the year ended December 31, 2015 due to higher personnel-related expenses primarily driven 
by  an  increase  in  headcount  from  433  employees  as  of  December 31,  2015  to  521  employees  as  of 
December 31, 2016. 

Share-based compensation decreased by € 7.4 million, or 67.9%, in the year ended December 31, 2017 
compared to the year ended December 31, 2016, which was primarily driven by fluctuations in the fair value 
accounting treatment of awards which were classified as liability awards in the prior periods. Share-based 
compensation increased by € 7.5 million, or 220.6%, in the year ended December 31, 2016 compared to the 
year  ended  December 31,  2015,  which  was  primarily  driven  by  fluctuations  in  the  fair  value  accounting 
treatment of liability classified awards granted in prior periods.

Technology and content

Technology  and  content  expense  generally  consists  of  expenses  for  technology  development,  product 
development  and  content  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, 2017 increased by € 0.5 million, or 1.0%, 
compared  to  the  year  ended  December 31,  2016.  The  increase  was  primarily  driven  by  increases  in 
personnel-related costs as we grew our headcount and made investments in content expansion, which was 
largely  offset  by  lower  share-based  compensation  expense.  The  increase  in  personnel-related  costs 
amounted to € 10.0 million, or 41.7%, as we continue to make investments in product content and therefore 
increased  our  headcount  from  499  employees  as  of  December 31,  2016  to  652  employees  as  of 
December 31,  2017.  This  increase  in  personnel-related  costs  was  largely  offset  by  lower  share-based

compensation  of  € 12.2 million, or  77.2%, which  was  due to  the  fluctuations  in  the  fair  value  accounting

increased by € 2.6 million, or 32.5%, as we continued to invest in projects related to visual content, hotel 
description and profiling to improve the quality of our product, which incurred higher website development 
expenses. In addition, depreciation of technology assets increased by € 0.1 million, or 2.6% in the year ended 
December 31, 2017 compared to the year ended December 31, 2016.

Technology  and  content  expense  for  the  year  ended  December 31,  2016  increased  by  € 23.0  million,  or 
80.1%, compared to the year ended December 31, 2015, primarily due to an increase of € 11.3 million, or 
251.1% in share-based compensation driven by fluctuations in the fair value accounting treatment of awards 
which were classified as liability awards in the prior periods, and an increase in personnel-related costs of 
€ 7.0 million, or 41.2%, to support key technology projects primarily for our corporate technology function, 
which resulted in an increase in headcount from 381 employees as of December 31, 2015 to 499 employees 
as of December 31, 2016. In addition, depreciation of technology assets increased by € 2.5 million, or 178.6%, 
and professional fees and other expenses increased by € 2.2 million, or 37.9%, in the year ended December 
31, 2016.

General and administrative

General and administrative expense consists primarily of professional fees for external services including 
legal, tax and accounting, personnel-related costs, including those of our executive leadership, finance, legal 
and human resource functions, shared services costs calculated and allocated by Expedia to us, and other 
costs including other overhead costs, depreciation and share-based compensation.

General and administrative expense for the year ended December 31, 2017 decreased by € 8.2 million, or 
14.7%, compared to the year ended December 31, 2016, primarily due to a decrease of € 17.5 million of 
share-based compensation expense mainly driven by fluctuations in the fair value accounting treatment of 
awards which were classified as liability awards in the prior periods. Professional fees and other for the year 
ended December 31, 2017 increased by € 7.9 million, or 51.6% compared to the year ended December 31, 
2016, mainly driven by an increase of €7.0  million in legal and consulting fees, including audit and financial 
consultancy fees. At the same time, legal, tax, and other service costs performed by Expedia on our behalf 
that  were  pushed  down  to  us  declined  by  €4.1  million.  Personnel-related  costs  for  the  year  ended 
December 31, 2017 increased by € 5.5 million, or 56.1%, compared to the year ended December 31, 2016, 
primarily driven by an increase in headcount in our Human Resources and Finance departments from 187
employees as of December 31, 2016 to 291 employees as of December 31, 2017 as we continued to build 
up internal expertise in these areas. 

General and administrative expense for the year ended December 31, 2016 increased by € 37.5 million, or 
207.2%,  compared  to  the  year  ended  December 31,  2015,  primarily  due  to  an  increase  in  share-based 
compensation expense of € 20.3 million, which was primarily driven by fluctuations in the fair value accounting 
treatment of liability classified awards granted in prior periods. Professional fees and other for the year ended 
December 31, 2016 increased by €1 1.4 million, or 292.3%, compared to the year ended December 31, 2015, 
a significant portion of which was due to an increase of € 5.1 million in professional fees incurred primarily 
in conjunction with the preparation of the registration statement filed with the SEC on December 5, 2016 in

connection with our IPO, including consolidated U.S. GAAP financial statements and related audits. Other 
factors contributing to the increase included an increase in bad debt expense of €3.5  million, higher overhead 
costs due to increased headcount of €1.4  million, rent expense associated with the build-to-suit lease for 
our new corporate headquarters of €0.9  million and increased rent of €0.5  million. Personnel costs for the 
year  ended  December 31,  2016  increased  by  € 4.4  million,  or  81.5%,  compared  to  the  year  ended 
December 31, 2015, primarily driven by an increase in headcount from 121 employees as of December 31, 
2015  to  187  employees  as  of  December 31,  2016.  Further,  we  incurred  increased  related  party  shared 
service costs of € 1.4 million, or 50.0%, primarily attributable to an increase in legal, tax, treasury, audit and 
corporate reorganization that was incurred by Expedia on our behalf of €0.8  million and an increase in IPO 
and corporate reorganization costs of € 0.6 million pushed down by Expedia.

Amortization of intangible assets 

Amortization of intangible assets was € 3.2 million in the year ended December 31, 2017, and €13.9  million 
and  €30.0  million  in  the  years  ended  December 31,  2016  and  December 31,  2015,  respectively.  The 
decreases of €10.7  million and €16.1  million for the years ended December 31, 2017 and December 31, 
2016, respectively, are due to certain technology assets that were fully amortized during the first quarters 
of 2017 and 2016, respectively. The amortization costs relate predominantly to intangible assets recognized 
by Expedia upon the acquisition of a majority stake in trivago GmbH in 2013. The financial statements reflect 
Expedia’s basis of accounting due to this change in control in 2013.

Operating loss 

Our operating loss was € 20.4 million for the year ended December 31, 2017 compared to an operating loss 
of € 44.4 million for the year ended December 31, 2016. We have seen our operating loss decrease when 
compared to the year ended December 31, 2016. Selling and marketing expenses reflected our inability to 
pull  back  planned TV  advertising  spend  due  to  commitments  in  some  markets.  Our  operating  loss  was 
impacted by a slight increase in technology and content costs and a decrease in general and administrative 
expenses,  including  lower  share-based  compensation  primarily  driven  by  fluctuations  in  the  fair  value 
accounting  treatment  of  awards  which  were  classified  as  liability  awards  in  the  prior  periods  and  lower 
amortization of intangible assets.

Our operating loss was € 44.4 million for the year ended December 31, 2016 compared to an operating loss 
of € 47.9 million for the year ended December 31, 2015. The operating loss decreased primarily due to higher 
growth in revenue combined with a lower amortization of intangible assets, partially offset by increased costs 
and expenses, particularly relating to share-based compensation primarily driven by fluctuations in the fair 
value accounting treatment of liability classified awards granted in prior periods.

Other, net 

Other, net is primarily comprised of a foreign exchange loss of € 1.0 million and gains of € 0.0 million and 
€ 0.1 million for the years ended December 31, 2015, 2016 and 2017, respectively, as well as income from 
ADSs offset by custodial fees related to ADSs of € 0.3 million for the year ended December 31, 2017, other 
expenses of € 0.2 million for the year ended December 31, 2016 and the reversal of an indemnification asset 
related to an uncertain tax position and the related interest of € 1.7 million for the year ended December 31, 
2015.

Our effective tax rate was 26.7% in 2017, (14.9)% in 2016 and 22.3% in 2015. This is mainly due to non-
deductible share-based compensation of (pre-tax) € 16.0 million in 2017, € 53.7 million in 2016 and € 14.1 
million in 2015. Furthermore, corporate costs were pushed down from Expedia of (pre-tax) €0.5  million for 
2017, €4.2  million  for  2016 and  €2.8  million  for 2015,  which  are non-deductible  for tax  purposes.  Other 
differences  relate  to  one-off  items  during  the  year.  In  2017,  €3.2  million  is  related  to  the  recognition  of 
previously unrecognized net operating losses. In 2016, €1.9  million is related to tax losses of the current 
year for which no deferred tax asset was recognized (valuation allowance). In 2015, €0.5  million of the total 
€0.8  million was related to the non-tax deductible expense for the release of a contingent asset at the level 
of trivago GmbH. 

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 credit facility, 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 

Because the interest rate on our credit facility is tied to a market rate, we will be susceptible to fluctuations 
in interest rates if, consistent with our practice to date, we do not hedge the interest rate exposure arising 
from any advances under our credit facility. For the years ending December 31, 2017 and 2016, we had no 
amounts outstanding under our credit facility, and as of December 31, 2015, we had € 20.0 million outstanding. 
Expedia currently guarantees our credit facility. If Expedia does not continue to guarantee our credit in the 
future, our borrowing costs could increase. 

We did not experience any significant impact from changes in interest rates for the years ended December 31, 
2015, 2016 or 2017. 

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. 

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 

74

€
€
€
would recognize foreign exchange losses of €1.6  million based on the net asset or liability balances of our 
foreign denominated cash, accounts receivable, and accounts payable balances as of December 31, 2017. 
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 years ended December 31, 2015, 2016 and 2017, we recorded net foreign exchange rate gains 
(losses) of €(1.0)  million, €0.0  million and €0.1  million, respectively. 

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 and affiliates represented 39%, 36% and 36% of 
our revenue for the years ended December 31, 2015, 2016 and 2017, respectively, and 55%, 31% and 47%
of total accounts receivable as of December 31, 2015, 2016 and 2017, respectively. Booking Holdings and 
its affiliates represented 27%, 43% and 44% of our revenue for the years ended December 31, 2015, 2016
and 2017, respectively, and 21%, 48% and 28% of total accounts receivable as of December 31, 2015, 2016
and 2017, respectively. 

Critical Accounting Policies and Estimates 

Our Operating and Financial Review is based on our consolidated financial statements and accompanying 
notes, which we have prepared in accordance with U.S. GAAP. The 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 and disclosure of contingent assets and liabilities as of the date 
of our consolidated financial statements. These estimates and assumptions also affect the reported amount 
of  net  income  or  loss  during  any  period.  Our  actual  financial  results  could  differ  significantly  from  these 
estimates.  The  significant  estimates  underlying  our  consolidated  financial  statements  include  revenue 
recognition;  recoverability  of  current  and  long-lived  assets,  intangible  assets  and  goodwill;  income;  loss 
contingencies; redeemable non-controlling interests; acquisition purchase price allocations; and share-based 
compensation. There have been no material adjustments to prior period estimates for any of the periods 
included in this annual report. 

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. 

See Note 2—Significant accounting policies, in the notes to our consolidated financial statements appearing 
elsewhere in this annual report for a description of all of our significant accounting policies. We believe that 
the following accounting policies are the most critical to aid you in fully understanding and evaluating our 
financial condition and results of operations. 

Revenue recognition 

We recognize revenue from services rendered when it is earned and realizable based on the following criteria: 
persuasive  evidence  of  an  arrangement  exists,  services  have  been  rendered,  the  price  is  fixed  or 
determinable, and collectability is reasonably assured. 

75

Revenue is generated each time a visitor to one of our websites or apps clicks on a hotel room offer in our 
search results and is referred to one of our advertisers. Advertisers pay on a per referral basis, with the 
aforementioned visitor click-through being considered a single referral. Given the nature of the industry, it 
is not unusual for referrals to be generated from automated scripts designed to browse and collect data on 
our websites. However, review processes are in place to identify anomalies to ensure revenue recognition 
is appropriate. Pricing is determined through a competitive bidding process whereby advertisers bid on their 
placement priority for a specific room offer within each room listing. Bids can be placed as often as daily, 
and changes in bids are applied on a prospective basis on the following day. Additionally, a portion of our 
revenue  is  generated  through  subscription-based  services  earned  through  trivago  Hotel  Manager  Pro 
applications. This revenue is recognized ratably over the subscription period and deferred revenue is recorded 
on the balance sheet for amounts invoiced in advance of revenue recognition.

Leases 

We lease office space in several countries under non-cancelable lease agreements. We generally lease our 
office facilities under operating lease agreements. We recognize rent expense on a straight-line basis over 
the lease period. Any lease incentives are recognized as reductions of rental expense on a straight-line basis 
over the term of the lease. The lease term begins on the date we become legally obligated for the rent 
payments or when we take possession of the office space, whichever is earlier.

We establish assets and liabilities for the estimated construction costs incurred under lease arrangements 
where we are considered the owner for accounting purposes only, or build-to-suit leases, to the extent that 
we  are  involved  in  the  construction  of  structural  improvements  or  take  construction  risk  prior  to 
commencement of a lease.

In July 2015, we entered into a lease for new corporate headquarters with 26,107 square meters of office 
space. Pursuant to the lease, the Landlord will build this office building in Düsseldorf, Germany. As a result 
of our involvement in the construction project and our responsibility for paying a portion of the costs of normal 
finish work and structural elements of the premises, the Company was deemed for accounting purposes to 
be  the  owner  of  the  premises  during  the  construction  period  pursuant  to  build-to-suit  lease  accounting 
guidance  under  ASC  840.  Therefore,  the  Company  recorded  project  construction  costs  during  the 
construction period incurred by the landlord as a construction-in-progress asset and a related construction 
financing obligation on our consolidated balance sheets. The amounts that the Company has paid or incurred 
for  normal  tenant  improvements  and  structural  improvements  had  also  been  recorded  as  part  of  the 
construction-in-progress asset.

We have a lease that includes both building and land. We have bifurcated our lease payments pursuant to 
the premises into: a portion that is allocated to the building (a reduction to the financing obligation); and a 
portion that is allocated to the land on which the building was constructed. The portion of the lease obligations 
allocated to the land is treated as an operating lease that commenced in July 2015. For the years ended 
December 31, 2016 and 2017, we have recorded € 1.7 million and € 1.7 million respectively, of land rent 
expense in connection with this lease.

Recoverability of goodwill and indefinite-lived intangible assets 

Goodwill is assigned to our three reporting units, which correspond to our three operating segments, on the 
basis of their relative fair values as of the date of change in reporting units. We assess goodwill and indefinite-
lived assets, neither of which are amortized, for impairment annually in the fourth quarter of the year, or more 
frequently, if events and circumstances indicate that an impairment may have occurred. In the evaluation of 
goodwill for impairment, we typically first perform a qualitative assessment to determine whether it is more 
likely than not that the fair value of each reporting unit is less than its carrying amount, followed by performing 
a quantitative assessment by comparing the fair value of the reporting unit to the carrying value, if necessary. 
Effective  October  1,  2017,  we  prospectively  adopted  accounting  guidance  that  simplified  our  goodwill 
impairment testing by eliminating the requirement to calculate the implied fair value of goodwill (formerly 
"Step 2") in the event an impairment is identified. Instead, an impairment charge is recorded based on the 
excess of the reporting unit's carrying amount over its fair value. 

76

We generally base the measurement of fair value of our three reporting units on a blended analysis of the 
present value of future discounted cash flows and market valuation approach. The discounted cash flows 
model indicates the fair value of the reporting unit based on the present value of the cash flows that we 
expect the reporting unit to generate in the future. Our significant estimates in the discounted cash flows 
model include our weighted average cost of capital, long-term rate of growth and profitability of our business. 
The market valuation approach indicates the fair value of the business based on a comparison of the reporting 
unit to comparable publicly traded firms in similar lines of business. Our significant estimates in the market 
approach  model  include  identifying  similar  companies  with  comparable  business  factors,  such  as  size, 
growth, profitability, risk and return on investment and assessing comparable revenue and operating income 
multiples in estimating the fair value of the reporting unit.

We believe the weighted use of discounted cash flows and market approach is the best method for determining 
the fair value of our reporting units because these are the most common valuation methodologies used within 
the travel and Internet industries, and the blended use of both models compensates for the inherent risks 
associated with either model if used on a stand-alone basis.

In addition to measuring the fair value of our reporting units as described above, we consider the combined 
carrying and fair values of our reporting units in relation to the company’s total fair value. 

In our evaluation of our indefinite-lived intangible assets, we typically first perform a qualitative assessment 
to determine whether the fair value of the indefinite-lived intangible assets is more likely than not impaired. 
If so, we perform a quantitative assessment and an impairment charge is recorded for the excess of the 
carrying value of the indefinite-lived intangible assets over the fair value. We base our measurement of the 
fair value of our indefinite-lived intangible assets, which consist of trade name, trademarks, and domain 
names 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. As with goodwill, periodically, we may choose to forgo the initial qualitative assessment and perform 
a quantitative analysis in our annual evaluation of indefinite-lived intangible assets.

Recoverability of intangible assets with definite lives and other long-lived assets 

Intangible assets with definite lives and other long-lived assets are carried at cost and are amortized on a 
straight-line basis over their estimated useful lives of generally less than seven years. We review the carrying 
value of long-lived assets or asset groups, including property and equipment whenever events or changes 
in circumstances indicate that the carrying amount of the assets might not be recoverable. Factors that would 
necessitate an impairment assessment include a significant adverse change in the extent or manner in which 
an asset is used, a significant adverse change in legal factors or the business climate that could affect the 
value of the asset, or a significant decline in the observable market value of an asset, among others. If such 
facts indicate a potential impairment, we would assess the recoverability of an asset group by determining 
if the carrying value of the asset group exceeds the sum of the projected undiscounted cash flows expected 
to result from the use and eventual disposition of the assets over the remaining economic life of the primary 
asset in the asset group. If the recoverability test indicates that the carrying value of the asset group is not 
recoverable, we will estimate the fair value of the asset group using appropriate valuation methodologies, 
which would typically include an estimate of discounted cash flows. Any impairment would be measured as 
the difference between the asset group’s carrying amount and its estimated fair value.

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 

77

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,  tax  sharing 
agreements  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 and penalties related to uncertain tax positions are classified in the financial statements 
as a component of income tax expense.

Advertising expense 

We incur advertising expense consisting of offline costs, including television and radio advertising, as well 
as online advertising expense to promote our brands. A significant portion of traffic from users is directed to 
our  websites  through  our  participation  in  display  advertising  campaigns  on  search  engines,  advertising 
networks, affiliate websites and social networking sites. We consider traffic acquisition costs to be indirect 
advertising fees. We expense the production costs associated with advertisements in the period in which 
the  advertisement  first  takes  place.  We  expense  the  costs  of  communicating  the  advertisement  (e.g., 
television airtime) as incurred each time the advertisement is shown. These costs are included in selling and 
marketing expense in our consolidated statements of operations. For the years ended December 31, 2015, 
2016 and 2017, our advertising expense was € 432.2 million, € 623.5 million and € 884.7 million, respectively. 
As of December 31, 2015, 2016 and 2017, we had € 3.8 million, € 5.3 million and € 12.6 million, respectively, 
of prepaid marketing expenses included in prepaid expenses and other current assets.

Share-based compensation 

Share-based compensation included in our consolidated financial statements relates to certain outstanding 
trivago employee options replaced with new trivago employee option awards exercisable into trivago Class 
A shares, in connection with the controlling-interest acquisition of trivago by Expedia in 2013. During 2017, 
there were additional options granted in connection with the Omnibus Incentive Plan to employees of trivago. 

The fair value of share options accounted for as equity settled transactions is measured at the grant date 
using  the  Black–Scholes  option  pricing  model.  The  valuation  model  incorporates  various  assumptions 
including expected volatility of equity, expected term and risk-free interest rates. As we do not have a trading 
history relatable to the expected term of our awards, the expected share price volatility for our Class A shares 
was  estimated  by  taking  the  average  historic  price  volatility  for  industry  peers  based  on  daily  price 
observations over a period commensurate to the expected term. Prior to the IPO, we previously based our 
expected term assumptions on the terms and conditions of the employee share option agreements, and 
scheduled exercise windows. Post IPO, we have used the simplified method in determining the term by 
using the midpoint between the vesting date and the end of the contractual term to estimate the term for all 
option grants subsequent to the IPO. The simplified method was used as we do not have sufficient relatable 
historical term data is available. Prior to the IPO, the share price assumption used in the model is based 
upon a valuation of trivago’s shares as of the grant date utilizing a blended analysis of the present value of 
future discounted cash flows and a market valuation approach. Post IPO, the share price assumption used 
in the model is based our publicly traded share price on the date of grant. We amortize the fair value to the 
extent the awards qualify for equity treatment, over the vesting term on a straight-line basis. The majority of 
our share options are service-based awards which vest between one and three years and have contractual 
terms that align with prescribed liquidation windows.

We  have  performance-based  share  options  which  vest  upon  achievement  of  certain  company-based 
performance conditions and service conditions. On the date of grant, we determine the fair value of the 
performance-based award using the Black-Scholes option pricing model. The awards are then assessed to 

78

determine the probability of the award vesting. If assessed as probable, we record compensation expense 
for  these  awards  over  the  total  performance  and  service  period  using  the  accelerated  method. At  each 
reporting period, we reassess the probability of achieving the performance targets, which requires judgment, 
and to the extent actual results or updated estimates differ from our current estimates, the cumulative effect 
on current and prior periods of those changes will be recorded in the period estimates are revised, or the 
change in estimate will be applied prospectively depending on whether the change affects the estimate of 
total  compensation  cost  to  be  recognized.  The  ultimate  number  of  shares  issued  and  the  related 
compensation expense recognized will be based on a comparison of the final performance metrics to the 
specified targets.

We classify certain employee option awards as liabilities when we deem it not probable that the employees 
holding the awards will bear the risk and rewards of stock ownership for a reasonable period of time. We 
remeasure these instruments at fair value at the end of each reporting period using a Black-Scholes option 
pricing model which relies upon an estimate of the fair value of trivago’s shares as of the reporting date 
which is determined using a blended approach as discussed above. Upon settlement of these awards, our 
total  share-based  compensation  expense  recorded  from  grant  date  to  settlement  date  will  equal  the 
settlement amount.

We recognize the effect of forfeitures in the period that the award was forfeited.

79

B. Liquidity and capital resources

On September 5, 2014, we entered into an uncommitted credit facility with Bank of America Merrill Lynch 
International Ltd. with a maximum principal amount of €10.0  million. Advances under this facility bear interest 
a rate of LIBOR, floored at zero, plus 1.0% per annum. This facility may be terminated at any time by the 
lender. Our obligations under this facility are guaranteed by Expedia. On December 19, 2014, we entered 
into an amendment to this facility pursuant to which the maximum principal amount was increased to €50.0 
million. We utilized €20.0  million of our €50.0  million credit facility to fund capital requirements in 2015. During 
the year ended December 31, 2016, we utilized €20.0  million under our credit facility and subsequently repaid 
all obligations outstanding. We did not utilize the credit facility during the year ended December 31, 2017.

For the year ended December 31, 2017, cash and cash equivalent decreased by € 37.1 million to €190.2 
million. The decrease was mainly driven by a negative cash flow from investing activities notably due to an 
increase in capital expenditures, and a negative cash flow from operating activities mainly resulting from 
accounts receivables increasing more than accounts payables as discussed in more detail below.

Our known material liquidity needs for periods beyond the next twelve months are described below in “Item 
5 F. Tabular disclosure of contractual obligations.” We believe that our cash from operations, together with 
our credit facility and cash balance are sufficient to meet our ongoing capital expenditures, working capital 
requirements and other capital needs for at least the next twelve months. 

 The following table summarizes our cash flows for the years ended December 31, 2015, 2016 and 2017:

Cash Flows Provided by/(Used in) Operating Activities 

For the year ended December 31, 2017, net cash used in operating activities increased by € 41.5 million to 
€ (10.3) million. This negative cash flow from operating activities was primarily driven by a change from a 
working  capital  benefit  in  2016  into  a  working  capital  deficit  in  2017  and  decreased  share-based 
compensation, due to a one-time call option exercised by Expedia in 2016. The working capital deficit was 
mainly driven by a standardization of related party payment terms, which delayed our receipt of related party 
revenue until after month-end close, resulting in increased accounts receivables.

For the year ended December 31, 2016, net cash provided by operating activities increased by € 32.1 million
to € 31.1 million of cash provided. This was primarily due to an increase in operating income (after adjusting 
for impacts of depreciation and amortization of €13.7  million) from 2015 to 2016 and a change from a working 
capital deficit in 2015 to a working capital benefit in 2016. 

For the year ended December 31, 2015, net cash used in operating activities increased by € 1.6 million, from 
€ 0.6 million for the year ended December 31, 2014 to € (1.0) million for the year ended December 31, 2015, 
primarily due to decreased benefits from working capital changes.

€
€
Cash Flows Used in Investing Activities 

For the year ended December 31, 2017, cash used in investing activities increased by € 9.3 million to € (18.3) 
million,  primarily  due  to  increased  capital  expenditures  including  internal-use  software  and  website 
development and the acquisition of tripl GmbH for € 0.7 million.

For the year ended December 31, 2016, cash used in investing activities increased by € 2.5 million to € (9.0) 
million,  primarily  due  to  increased  capital  expenditures  including  internal-use  software  and  website 
development and the acquisition of the base7 minority interest for € 0.9 million. 

For the year ended December 31, 2015, cash used in investing activities increased by € 1.9 million, from 
€ (4.6) million for the year ended December 31, 2014 to € (6.5) million for the year ended December 31, 2015, 
primarily due to acquisitions and increased capital expenditures including internal-use software and website 
development. 

Cash Flows Provided by/(Used in) Financing Activities 

For the year ended December 31, 2017, cash used in financing activities increased by € 194.9 million to € 7.2 
million of cash used. This was driven primarily by one-time IPO net proceeds in 2016 of € 207.8 million, 
partially offset by a € 20.0 million net payment on the credit facility during the year ended December 31, 2016. 
The negative cash flow from financing activities in 2017 was primarily due to payments of IPO costs of € 4.0 
million and tax payments for shares withheld of € 3.1 million.

For the year ended December 31, 2016, cash provided by financing activities increased by € 168.7 million
to € 187.6 million. This was driven primarily by IPO net proceeds of € 207.8 million, and a € 20.0 million draw 
down on the credit facility during the year ended December 31, 2015 compared to a € 20.0 million net payment 
on the credit facility during the year ended December 31, 2016.

For the year ended December 31, 2015, cash provided by financing activities increased by € 18.0 million
million,  from  € 1.0  million  for  the  year  ended  December 31,  2014  to  € 19.0  million  for  the  year  ended 
December 31, 2015 and primarily included € 20.0 million in proceeds from a draw-down of our credit facility, 
partially offset by the repayment of a € 1.0 million loan from Expedia.

(1)  Currently recognized on our balance sheet as of December 31, 2017 is an asset retirement obligation of €1.0  million related to 
our  main  headquarters  located  in  Düsseldorf,  Germany.  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. 

(2)  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.

On February 28, 2017, we announced that Andrej Lehnart, Malte Siewert and Peter Vinnemeier would step back from their roles 
as managing directors at the general meeting of shareholders in June 2018. For more information, see "—New leadership structure" 
below.

The following paragraphs set forth biographical information regarding our management board members.

Axel Hefer was initially appointed as a managing director of the company in 2016 and served as a managing 
director of trivago GmbH from 2016 until the post-IPO merger. He also serves as a non-executive director

New leadership structure

On February 28, 2018, our supervisory board approved a new streamlined leadership structure for trivago. 
The new structure reduces the number of managing directors in our management board from six to three, 
and is designed to increase flexibility and to simplify its corporate governance structure. As a consequence, 
the  supervisory  board  will  nominate  Rolf  Schrömgens,  Johannes Thomas  and Axel  Hefer  as  managing 
directors for appointment at the general meeting of shareholders in June 2018. The other current managing 
directors in the leadership team will step back from their roles as managing directors at that time.

Along with the remaining managing directors, Andrej Lehnert and Anna Drüing (covering human resource 
topics) will continue to serve as part of the trivago’s leadership team, while Peter Vinnemeier and Malte 
Siewert will continue to advise the company in consulting roles.

While currently the managing directors serve for a term of one year each, the supervisory board resolved 
to nominate Axel Hefer for appointment at our general meeting in June 2018 for a term of five years.

In September 2017, we also announced changes to our supervisory board. After receiving the resignation 
of Dara Khosrowshahi as member and chairman of the Company’s Supervisory Board, the supervisory board 
elected  Mark  Okerstrom,  President  and  Chief  Executive  Officer  of  Expedia,  Inc.,  as  chairman  of  the 
supervisory board. In addition, Robert Dzielak, Executive Vice President, General Counsel and Secretary 
of Expedia, Inc., was designated as temporary member of the supervisory board, pending his appointment 
by trivago’s general meeting of shareholders in June 2018.

(1)  As described further in this report, 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 received certain a 
portion of trivago N.V. options in addition 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 

87

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.

The amount of compensation, including benefits in kind, accrued or paid to our supervisory board members 
with respect to the year ended December 31, 2017 is described in the tables below. Our supervisory board1

As of December 31, 2017, we have nothing set aside or accrued to provide pension, retirement or similar 
benefits  to  our  supervisory  board  members.  In  the  year  2017,  none  of  our  supervisory  board  member 
exercised any options in trivago N.V.

88

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, directors who are members of the management board 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 shall be 34,711,009 Class A shares. 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.

Plan  administration.    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 agreed with the supervisory board. Subject to applicable 
law or the listing standards of the applicable exchange, the plan committee may delegate to other appropriate 
persons the authority to grant equity awards under the 2016 Plan to our eligible award recipients.

Eligibility.    Management board members, supervisory board members, officers, employees and consultants 
of the company or any of our subsidiaries or affiliates, and any prospective directors, officers, employees 
and consultants of the company who have accepted offers of employment or consultancy from the company 
or our subsidiaries or affiliates (excluding supervisory board members) are eligible for awards under the 
2016 Plan.

Awards.    Awards include options, share appreciation rights, restricted share units and other share-based 
and  cash-based  awards. Awards  may  be  settled  in  stock  or  cash. The  option  exercise  price  for  options 
granted  to  members  of  the  management  board  and  the  supervisory  board  under  the  2016  Plan  for 
management board members shall not be less than the fair market value of a Class A share as defined in 
the 2016 Plan on the relevant grant date, unless otherwise approved by shareholders at a general meeting. 
The option exercise price for options under the 2016 Plan for other eligible individuals can be less than the 
fair market value of a Class A share as defined in the 2016 Plan on the relevant grant date. To the extent 
that listing standards of the applicable exchange require the company’s shareholders to approve any repricing 
of options, options may not be repriced without shareholder approval.

Vesting period.    Options and share appreciation rights shall vest and become exercisable at such time and 
pursuant to such conditions as determined by the plan committee and as may be specified in an individual 
grant agreement. The plan committee may at any time accelerate the exercisability of any option or share 
appreciation right. Restricted shares may vest based on continued service, attainment of performance goals 
or both continued service and performance goals. The plan committee at any time may waive any of these 
vesting conditions.

Term.    Options and share appreciation rights will have a term of not more than ten years. The 2016 Plan 
will also have a ten year term, although awards outstanding on the date the 2016 Plan terminates will not 
be affected by the termination of the 2016 Plan.

Compensation principles

Senior management

The primary objective of our senior management’s compensation program is to attract, motivate, reward and 
retain  the  managerial  talent  needed  to  achieve  our  business  objectives.  In  addition,  compensation 
arrangements for our senior management have been designed to align a portion of their compensation with 
the achievement of our business objectives and growth strategy. Bonus payments for our senior management 
are determined with respect to a given year based on quantitative and qualitative goals set for our company, 
as well as on an individual basis. Once the results of the year are known, bonus payments and any equity 
award compensation are determined at the discretion of our board and, with respect to senior management 
reporting to the CEO, considering recommendations made by the CEO.

89

Employees 

We believe in cultivating an inspiring environment where our employees can thrive and feel empowered to 
do their best. Our aim is to attract intrinsically motivated individuals, and nurture and retain the most capable 
and driven of them to support our culture of learning, authenticity and entrepreneurship. 

Our remuneration policy is designed to attract and retain employees, and reward them for achieving our 
goals and  objectives as a business,  and in particular  our  “core  values"  (see  above “Item  4 B. Business 
overview—Our employees and culture”). We believe our employees’ compensation should develop together 
with their career development, achievements and the value they create at trivago. We have an individualized 
approach to compensation that reflects each employee’s unique context and overall value contribution to 
our  organization.  We  believe  that  employees  who  contribute  to  our  success  should  receive  increased 
compensation, for example through the award of stock options.

Salaried  employees  are  rewarded  on  a  total  rewards  basis,  which  includes  fixed  income  and  long-term 
incentive  awards,  such  as  stock  options.  We  also  offer  all  our  employees  other  benefits,  such  as  self-
determined hours, a supportive work environment and an attractive culture. We aim to ensure that each 
employee’s compensation is fair and is aligned to the scope and breadth of his or her activities as well as 
to the value that person creates. At trivago, we review our compensation decisions on a yearly basis. We 
believe that fairness is created by analyzing compensation at one point in time for all our employees. Rather 
than negotiating salary increases, we aim to run a fair, objective and merit-based process for compensation 
decisions. 

Short-term remuneration policy

An important component of our remuneration policy is the use of the short-term incentive remuneration, 
which supports our results-focused culture and the engagement of our employees. We believe in making 
appropriate  and  meaningful  distinctions  in  recognizing  and  rewarding  our  employees’  performance.  We 
complement  the  base  compensation  of  our  employees  by  offering  ad-hoc  bonuses  (rewarded  by  a 
responsibility lead for creating extraordinary value) and peer bonuses (a special and unexpected thanks for 
extraordinary efforts, awarded by other employees).

90

C. Board practices

Management board and supervisory board

We have a two-tier board structure consisting of our management board (bestuur) and a separate supervisory 
board (raad van commissarissen). Each management board and supervisory board member owes a duty 
to us to properly perform the duties assigned to him or her and to act in our corporate interest. Under Dutch 
law,  the  corporate  interest  extends  to  the  interests  of  all  corporate  stakeholders,  such  as  shareholders, 
creditors, employees, customers and suppliers. 

Management board 

Our management board is responsible for the day-to-day management of our company, subject to certain 
limitations as set out in the articles of association and the internal rules of our management board (which 
we refer to as the Management Board Rules), and for our strategy, policy and operations subject to the

The  management  board  shall,  in  due  course  at  least  30  days  before  the  end  of  each  fiscal  year  of  the 
company, prepare and submit to the supervisory board an annual business plan for the following fiscal year. 
The annual business plan shall become effective upon the approval of the supervisory board, and the annual 
business  plan  may  be  amended  by  the  management  board  by  a  quarterly  plan  with  the  consent  of  the 
supervisory board. The annual business plan will address, in reasonable detail, any anticipated transactions 
of the type described in Item 1 above. The fiscal year of the company is the calendar year. 

If, at the beginning of a fiscal year, no new annual business plan is in effect because the supervisory board 
did not approve the annual business plan submitted by the management board or the management board 
did not submit an annual business plan as and when required hereunder, the annual business plan for the 
previous business year shall stay in effect until such time when the supervisory board approves a new annual 

92

business plan for the running fiscal year, provided that the target figures for revenue and adjusted EBITDA 
shall increase by 15% to the previous annual business plan and expense items shall be adjusted accordingly. 

Our management board is comprised of six members, and must consist of at least three members. Our 
management board members have been appointed pursuant to our deed of incorporation. The composition 
of our management board will be subject to the rights of the Founders and Expedia under the Amended and 
Restated Shareholders’ Agreement. 

Under our articles of association, the supervisory board may elect one management board member to be 
the chief executive officer and another management board member to be the chief financial officer subject 
to the terms of the Amended and Restated Shareholders’ Agreement. The supervisory board may revoke 
the title chief executive officer or chief financial officer subject to the terms of the Amended and Restated 
Shareholders’ Agreement, provided that such management board member shall subsequently continue his 
term of office as a management board member without having the title of chief executive officer or chief 
financial officer, respectively. 

Our management board members were appointed by our general meeting of shareholders upon the binding 
nomination  by  the  supervisory  board.  Under  Dutch  law,  a  management  board  member  may,  subject  to 
compliance with certain Dutch statutory procedures, be removed with or without cause by a resolution passed 
by a majority of at least a two thirds of the votes cast by those present in person or by proxy at a meeting 
and who are entitled to vote, provided such majority represents more than half of the issued share capital, 
unless the proposal was made by the supervisory board in which case a simple majority of the votes cast 
is sufficient. 

Supervisory board 

Our supervisory board is responsible for supervising the conduct of and providing advice to our management 
board and for supervising our business generally, subject to our articles of association, the Amended and 
Restated Shareholders’ Agreement and the internal rules of our supervisory board (which we refer to as 
Supervisory Board Rules). Our supervisory board also has the authority to, at its own initiative, provide our 
management board with advice and may request any information from our management board that it deems 
appropriate. In performing its duties, our supervisory board is required to take into account the interests of 
our business as a whole. 

Our supervisory board is comprised of seven members, including one temporary board member (pending 
his appointment by the general meeting). Pursuant to the Amended and Restated Shareholders’ Agreement, 
four supervisory board members were selected by Expedia and three supervisory board members were 
selected by the Founders. Each supervisory board member was appointed for a term of three years. 

Our supervisory board members were appointed by the general meeting of shareholders upon the binding 
nomination by our supervisory board. Pursuant to the Amended and Restated Shareholders’ Agreement, 
Expedia  and  the  Founders  have  agreed  that  any  new  supervisory  board  member  will  be  proposed  for 
nomination by either Expedia or the Founders as applicable, depending on which supervisory board member 
resigns, is not reappointed to, or is removed from the supervisory board. Expedia and the Founders have 
agreed to consult one another on their respective proposals. A supervisory board member may, subject to 
compliance with certain Dutch statutory procedures, be removed with or without cause by a shareholder 
resolution passed by a majority of at least a two thirds of the votes cast by those present in person or by 
proxy at a meeting and who are entitled to vote, provided such majority represents more than half of the 
issued share capital, unless the proposal was made by the supervisory board in which case a simple majority 
of the votes cast is sufficient. Pursuant to the Amended and Restated Shareholders’ Agreement, Expedia 
and the Founders have agreed that Expedia may designate the chairman of the supervisory board. The 
chairman will be entitled to cast a tie-breaking vote. 

93

Management board member services agreements 

We have entered into services agreements with each of the members of our management board. These 
agreements  contain  customary  provisions  regarding  noncompetition,  nonsolicitation,  confidentiality  of 
information and assignment of inventions. 

Supervisory board member services agreements 

We have entered into services agreements with each of the members of our supervisory board for an indefinite 
period of time, provided that the agreements will terminate upon dismissal, resignation or expiry of term of 
office (subject to reappointment) of the supervisory board member concerned. These agreements provide 
for the compensation awarded to the independent supervisory board members.

Director independence 

As a foreign private issuer under the SEC rules, we are not required to have independent directors on our 
supervisory  board,  except  to  the  extent  that  our Audit  Committee  is  required  to  consist  exclusively  of 
independent  supervisory  board  members.  However,  our  supervisory  board  has  determined  that,  under 
current Nasdaq listing standards regarding independence, and taking into account any applicable committee 
standards, Messrs. Kern, Mazzella, Östberg and Schneider would be considered independent supervisory 
board members. 

Under the independence criteria of the DCGC (which requires that our supervisory board be composed of 
independent  members,  except  for  no  more  than  one  member  who  is  not  independent),  Messrs.  Kern, 
Mazzella, Östberg and Schneider will be independent supervisory board members. See “Item 16 G. Corporate 
governance.”

Committees of the supervisory board 

Our supervisory board has established an audit committee and a compensation committee. 

Audit Committee 

The audit committee consists of Messrs. Kern, Östberg, and Schneider and assists the supervisory board 
in overseeing our accounting and financial reporting processes and the audits of our financial statements. 
Mr. Kern serves as chairman of the committee. The audit committee consists exclusively of members of our 
supervisory  board  who  are  financially  literate,  and  Mr. Kern  is  considered  an  “audit  committee  financial 
expert” as defined by the SEC. Our supervisory board has made an affirmative determination that each of 
our audit committee members is independent under Nasdaq rules and Rule 10A-3 of the Exchange Act. The 
audit committee is governed by a charter that complies with Nasdaq rules.  

Mr. Alan Pickerill has observer status on our Audit Committee, and he is the Chief Financial Officer of Expedia, 
Inc., our majority shareholder. He is relying on an exemption of the Nasdaq listing standards relating to Audit 
Committees  of  Rule  10A-3  promulgated  under  the  Exchange Act.  See "Item  16  D. Exemptions  from  the 
listing requirements and standards for audit committees."

The audit committee is responsible for: 

• 

• 

the appointment, compensation, retention and oversight of the work of, and the relationship with, the 
independent registered public accounting firm; 

the appointment, compensation, retention and oversight of any accounting firm engaged for the purpose 
of preparing or issuing an audit report or performing other audit services; 

•  pre-approving the audit services and non-audit services to be provided by our independent auditor before 

the auditor is engaged to render such services; 

•  evaluating the independent auditor’s qualifications, performance and independence, and presenting its 

conclusions to the full supervisory board on at least an annual basis; 

94

•  reviewing and discussing with the management board and the independent auditor our annual audited 
financial statements and quarterly financial statements prior to the filing of the respective annual and 
quarterly reports; 

•  reviewing our compliance with laws and regulations, including major legal and regulatory initiatives and 
also reviewing any major litigation or investigations against us that may have a material impact on our 
financial statements; and 

•  approving or ratifying any related person transaction (as defined in our related person transaction policy) 

in accordance with our related person transaction policy. 

The audit committee will meet as often as one or more members of the audit committee deem necessary, 
but in any event will meet at least four times per year. The audit committee will meet at least once per year 
with our independent accountant, without members of our management board being present. 

Compensation committee 

The compensation committee consists of Mrs. De Schepper and Messrs. Dzielak and Okerstrom, and assists 
the supervisory board in determining the compensation of the management board and the supervisory board, 
in accordance with the remuneration policy that has been determined by the general meeting of shareholders. 
Mr. Okerstrom serves as chairman of the committee. Under SEC and Nasdaq rules, there are heightened 
independence standards for members of the compensation committee, including a prohibition against the 
receipt of any compensation from us other than standard supervisory board member compensation. Pursuant 
to exemptions from such independence standards as a result of being a controlled company, the members 
of our compensation committee may not be independent under such standards. 

The compensation committee is responsible for: 

•  recommending each Managing Director’s compensation to the Supervisory Board and recommending to 

the Supervisory Board regarding compensation for Supervisory Board members;

• 

identifying,  reviewing  and  approving  corporate  goals  and  objectives  relevant  to  management  and 
supervisory board compensation; 

•  reviewing and approving or making recommendations regarding our incentive compensation and equity-

based plans and arrangements;

•  reviewing and discussing with management the compensation disclosures to be included in filings and 

submissions with the SEC;

•  preparing an annual compensation committee report; and

•  reporting regularly to the supervisory board regarding its activities.

Item 7: Major shareholders and related party 
transactions

A. Major Shareholders

The following table sets forth information relating to the beneficial ownership of our shares as of March 2, 
2018, by: 

•  each person, or group of affiliated persons, known by us to beneficially own 5% or more of our outstanding 

Class A shares; 

•  each member of our management board and our supervisory board; and 

•  each member of our management board and our supervisory board as a group.

For  further  information  regarding  material  transactions  between  us  and  principal  shareholders,  see  “B.
Related party transactions” below. 

The  number  of  shares  (or  share  capital)  beneficially  owned  by  each  entity,  person,  management  board 
member and supervisory board member is determined in accordance with the rules of the SEC, and the 
information is not necessarily indicative of beneficial ownership for any other purpose. Under such rules, 
beneficial  ownership  includes  any  shares  over  which  the  individual  has  sole  or  shared  voting  power  or 
investment power or from which the individual has the right to receive the economic benefit as well as any 
shares that the individual has the right to acquire within 60 days of March 2, 2018 through the exercise of 
any option, warrant or other right. Such shares are deemed outstanding for the purposes of computing the 
percentage ownership of the person holding such rights, but are not deemed outstanding for purposes of 
computing the percentage ownership of any other person, except with respect to the percentage ownership 
of all managing directors and supervisory board members as a group. Except as otherwise indicated, and 
subject  to  applicable  community  property  laws,  the  persons  named  in  the  table  have  sole  voting  and 
investment power and the right to receive the economic benefit with respect to shares held by that person. 

The  following  table  is  presented  as  of  March  2,  2018.  See  “Item  4  C.  Information  on  the  Company—
Organizational structure” for additional information regarding the corporate reorganization. Unless otherwise 
indicated below, the address for each beneficial owner listed is c/o trivago N.V., Bennigsen-Platz 1, 40474 
Düsseldorf, Federal Republic of Germany.

(1)  Percentages based on 30,916,474 Class A shares outstanding and 319,799,968 Class B shares outstanding as of December 31, 2017. 
Where the respective individual has the right to acquire within 60 days of February 27, 2018 through the exercise of any option, warrant 
or other right, such shares are deemed outstanding for the purposes of computing the percentage ownership of the person holding such 
rights, but are not deemed outstanding for purposes of computing the percentage ownership of any other person, except with respect to 
the percentage ownership of all managing directors and supervisory board members as a group. For more information on the stock options 
held by our management and supervisory boards, see "Item 6 B. Compensation of members of our management board and supervisory 
board".

 (2)  Percentage of total voting power represents voting power with respect to all of our Class A and Class B shares, as a single class. The 
holders of our Class B shares are entitled to ten votes per share, and holders of our Class A shares are entitled to one vote per share. For 
more information about the voting rights of our Class A and Class B shares, see “Description of share capital and articles of association
—Special voting structure and conversion” in our prospectus dated December 16, 2016. 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. 

(3)  As reported on Schedule 13G filed by Expedia Lodging Partner Services S.à r.l. (“ELPS”), Expedia holds its interest in the company through 
ELPS, an indirect wholly owned subsidiary of Expedia 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. Assuming conversion of all Class B shares 
beneficially owned by ELPS into Class A shares, ELPS would own 59.6% of our Class A shares. This percentage does not reflect the ten 
for one voting power of our Class B shares. Because each Class B share is entitled to ten votes per share and each Class A share is 
entitled to one vote per share, ELPS may be deemed to beneficially own equity securities representing approximately 64.7% of the voting 
power of the company. The address for Expedia is 333 108th Avenue NE, Bellevue, WA 98004.

Significant changes in ownership by major shareholders 

On  December  16,  2016,  we  completed  our  IPO,  in  which  we  and  the  Founders  sold,  in  the  aggregate, 
30,026,635 Class A shares primarily to new investors. As of December 31, 2017, assuming that all of our 
Class A shares represented by ADSs are held by residents of the United States, approximately 100% of our 
outstanding ADSs were held in the United States by one holder of record. At such date, there were 30,916,474 
ADSs outstanding, each representing one of our Class A shares, and in the aggregate representing 8.8% 
of our outstanding ordinary shares. At such date, there was one holder of record registered with Deutsche 
Bank Trust Company Americas, depositary of the ADSs. The actual number of holders is greater than these 
numbers of holders and includes beneficial owners whose ADSs are held in street name by brokers and 
other nominees. This number of holders of record also does not include holders whose shares may be held 
in trust by other entities.

B. Related party transactions

The following is a description of related party transactions we have entered into since January 1, 2015 with 
any of the members of our management board or supervisory board and the holders of more than 5% of our 
shares. 

Relationship with Expedia 

In 2013, Expedia completed the purchase of a 63% equity interest in the company, purchasing all outstanding 
equity not held by the Founders or employees for €477  million. During the second quarter of 2016, Expedia 
exercised its call right on certain shares held by non-Founder employees of the company, which were originally 
awarded in the form of stock options pursuant to the trivago employee stock option plan and subsequently 
exercised by such employees, and elected to do so at a premium to fair value resulting in a 63.5% ownership 
by Expedia. 

Amended and Restated Shareholders’ Agreement of trivago N.V. 

In connection with our IPO, travel B.V. (which subsequently converted into trivago N.V.), trivago GmbH, the 
Founders,  Expedia  Lodging  Partner  Services  S.à  r.l.  and  certain  other  Expedia  parties  entered  into  an 
amended  and  restated  shareholders’  agreement,  which  we  refer  to  as  the  Amended  and  Restated 
Shareholders’ Agreement. On August 22, 2017, the parties thereto amended the Amended and Restated 
Shareholders’ Agreement  to  make  a  technical  correction  to  the  definition  of  "Secondary  Shares"  in  the 
agreement.

Agreements regarding the supervisory board 

The Amended and Restated Shareholders’ Agreement provides that our supervisory board be comprised of 
seven members who will each serve for a three year term. Subject to applicable law, including applicable 
Nasdaq standards: (a) for so long as the Founders and their affiliates hold, collectively, at least 15% of the 
total  number  outstanding  of  Class A  and  Class  B  shares,  which  are  deemed  to  include  any  securities 
convertible into or exchangeable for, or any option, warrant, or other right to purchase or otherwise acquire, 
any Class A or Class B share (calculated as if all such securities had been converted, exercised or exchanged), 
the Founders will be entitled to designate for binding nomination three members to our supervisory board, 
all of whom must be independent; and (b) Expedia will be entitled to designate for binding nomination all 
other members of our supervisory board, one of whom will be the chairperson of the board with a tie breaking 
vote and, if the nominee is qualified, one of whom will be the chairman of our audit committee. Expedia will 
be entitled to increase or decrease the size of the supervisory board, provided that the number of members 
who the Founders are entitled to appoint is not less than three-sevenths (rounded to the nearest whole 
number) of the members of the supervisory board. 

The Amended and Restated Shareholders’ Agreement also sets forth agreements regarding the committees 
of the supervisory board and the rules of procedure. See “Item 6 C. Directors, senior management and 
employees—Board practices.” 

Our  supervisory  board  members  were  appointed  by  our  shareholders  acting  at  a  general  meeting  of 
shareholders upon a binding nomination by the supervisory board as described in “Item 6 C. Directors, senior 
management and employees—Board practices.” Therefore, Expedia and each Founder will be required to 
vote  the  shares  held  by  them  at  the  general  meeting  of  shareholders  in  accordance  with  the  voting 
arrangements set forth in the Amended and Restated Shareholders’ Agreement. 

Agreements regarding the management board 

Our management board is comprised of six members who have been appointed pursuant to our deed of 
incorporation. Pursuant to the Amended and Restated Shareholders’ Agreement, so long as certain conditions 

101

are met, the Founders who are then serving as management board members will be entitled to designate 
for binding nomination all six directors to our management board for so long as (i) the Founders and their 
affiliates, collectively, own at least 15% of the total number outstanding of Class A shares and Class B shares, 
which are deemed to include any securities convertible into or exchangeable for, or any option, warrant, or 
other right to purchase or otherwise acquire, any Class A or Class B share (calculated as if all such securities 
had been converted, exercised or exchanged) and (ii) a Founder is serving as chief executive officer of the 
company. Subject to certain conditions, so long as (i) the Founders and their affiliates, collectively, own at 
least 15% of the total number outstanding of Class A shares and Class B shares, which are deemed to 
include any securities convertible into or exchangeable for, or any option, warrant, or other right to purchase 
or otherwise acquire, any Class A or Class B share (calculated as if all such securities had been converted, 
exercised or exchanged) and (ii) any Founder and its affiliates hold at least 50% of the Class A shares and 
Class B shares, which are deemed to include any securities convertible into or exchangeable for, or any 
option, warrant, or other right to purchase or otherwise acquire, any Class A or Class B share (calculated 
as if all such securities had been converted, exercised or exchanged), such Founder owned upon completion 
of our IPO, such Founder will generally have a right to be designated by the Founders for binding nomination 
by the supervisory board to the management board. For purposes of determining a Founder’s rights described 
in clause (ii) of the prior sentence, certain sales in the first two years following the offering by such Founder 
of Class A shares, or securities convertible, exercisable or exchangeable for Class A shares, shall be treated 
as having been sold by such Founder in our IPO. The Founders shall only designate a former management 
board member for a new term if the circumstances initially warranting the removal, non-reappointment or 
resignation have changed, and the supervisory board in its sole discretion may choose not to designate such 
former management board member for binding nomination to the management board. 

Pursuant to the Amended and Restated Shareholders’ Agreement, certain transition arrangements have 
been agreed for succession of the chief executive officer. From the date that Mr. Schrömgens ceases to 
serve as chief executive officer, for a period of three years, which we refer to as the Transition Period, so 
long  as  a  Founder  is  serving  as  chief  executive  officer  and  there  is  no  set  of  circumstances  that  would 
constitute a reasonable cause, such Founder has the right to nominate a successor, subject to the approval 
of Expedia, and thereafter, the supervisory board. During the Transition Period, at the request of either the 
Founders or Expedia, (1) the supervisory board will be expanded by two seats, one of which will be filled by 
the Founders and one of which will be filled by Expedia, and (2) a three-person committee of the supervisory 
board will be formed which shall be entitled to nominate a chief executive officer, subject to the approval of 
Expedia,  and  thereafter,  the  supervisory  board,  in  the  event  that  a  chief  executive  officer  has  not  been 
nominated before the Founder serving as chief executive officer has ceased to serve as such. During the 
first eighteen months of the Transition Period, if the CEO is not a Founder, Expedia will have the right to 
designate for binding nomination two management board members and the chief executive officer will have 
the right to designate all other management board members, subject to approval by the supervisory board. 

Registration and other rights 

Pursuant to the Amended and Restated Shareholders’ Agreement, Expedia and the Founders have certain 
demand registration rights, short-form registration rights and piggyback registration rights in respect of any 
Class A shares and Class B shares, and related indemnification rights from the company, subject to customary 
restrictions and exceptions. All fees, costs and expenses of registrations, other than underwriting discounts 
and commissions, are expected to be borne by us. 

The Amended and Restated Shareholders’ Agreement also grants appropriate information rights to Expedia 
and the Founders. 

Expedia and the Founders also agreed in the Amended and Restated Shareholders’ Agreement that certain 
resolutions of the general meeting of shareholders require the consent of one Founder. 

Share transfer restrictions 

The Amended and Restated Shareholders’ Agreement provides certain restrictions on the transferability of 
the Class A shares and Class B shares held by Expedia and the Founders, including prohibitions on transfers 

102

by the Founders to our competitors. The Founders have tag-along rights on transfers of Class B shares to 
certain specified parties, and based on certain conditions. Expedia has the right to drag the Founders in 
connection with a sale of all of its Class A shares and Class B shares. Expedia and the Founders agreed to 
grant each other a right of first offer on any transfers of Class A shares or Class B shares to a third party. 

Call and put rights 

Pursuant to the Amended and Restated Shareholders’ Agreement, if a Founder is removed for reasonable 
cause, Expedia will have the right to purchase, and the Founder will be obligated to sell, all, but not less 
than all, of the Class A shares and Class B shares owned by such Founder, at a price based on a volume-
weighted average of the trading price of our Class A shares. 

If the general meeting of shareholders resolves to remove a Founder as a management board member 
without reasonable cause or if the supervisory board revokes the title of chief executive officer from a Founder 
then  serving  as  chief  executive  officer  without  either  (i)  reasonable  cause  or  (ii)  the  consent  of  another 
Founder, and the Founder terminates his services as management board member within 30 days thereof, 
then, the Founder will have the right to sell, and Expedia will be obligated to buy, all, but not less than all, of 
such Founder’s shares, at a price based on a volume-weighted average of the trading price of our Class A 
shares, unless a fact or circumstance exists which would be reasonably likely to result in the occurrence of 
any of the events in clauses (a) through (g) in the definition of reasonable cause set forth below. In such a 
case, no right to sell will be triggered by the removal of such management board member. 

Reasonable cause for purposes of the Amended and Restated Shareholders’ Agreement means, with respect 
to a management board member, the occurrence of any of the following: (a) the willful or gross neglect by 
the management board member of his or her fiduciary duties owed to the company or its subsidiaries; (b) the 
plea of guilty or nolo contendere to, or conviction for, the commission of a felony (or equivalent) offense by 
the  management  board  member;  provided,  that  for  purposes  of  this  clause  (b) if  a  management  board 
member is removed following being formally accused or charged with the commission of such an offense, 
and such management board member subsequently is convicted of (or pleads guilty or nolo contendere to) 
such offense, there will be deemed to have been reasonable cause at the time of the removal; (c) a material 
breach  (or  breaches  which,  when  aggregated  with  any  prior  breach  or  breaches,  are  material)  by  the 
management board member of his or her fiduciary duties owed to the company or any of its subsidiaries, or 
of the company's organizational documents; (d) a material breach by the management board member of 
any  nondisclosure,  non-solicitation,  or  noncompetition  obligation  owed  to  the  company  or  any  of  its 
subsidiaries; (e) a material failure (or failures which, when aggregated with any prior failure or failures, are 
material) to meet reasonable individual expectations in respect of his individual management duties in respect 
of the execution of his or her employment or duties as a management board member; (f) a material failure 
(or failures which, when aggregated with any prior failure or failures, are material) by the company to perform 
pursuant  to  the  annual  business  plan,  except  to  the  extent  that  the  failure  results  from  unforeseen 
circumstances and is responded to reasonably and appropriately by such management board member, and 
(g) any other fact or circumstance or action or inaction by such management board member, in each case 
constituting good cause under German law as interpreted by German courts. 

If the Founders have to sell ordinary shares to pay taxes realized in connection with the Post-IPO merger 
or to repay a loan obtained by the Founders to pay such taxes, the ownership levels at which they lose 
certain rights in the Amended and Restated Shareholders’ Agreement shall be equitably adjusted such that, 
in effect, all or a portion of the shares so sold are treated as having been retained by the Founders. 

IPO Structuring Agreement 

In connection with our IPO, travel B.V., the Founders, Expedia Lodging Partner Services S.à r.l., trivago 
GmbH, and certain other Expedia parties entered into an IPO structuring agreement, which we refer to as 
the IPO Structuring Agreement. Under the IPO Structuring Agreement, each of trivago N.V., trivago GmbH 
and each of the Founders requested tax rulings from the German tax authorities in connection with the Post-
IPO merger. On August 22, 2017, the parties thereto entered into a side letter to the IPO Structuring Agreement 
to confirm the parties' understandings with respect to the consummation of the Post-IPO merger.

103

Contribution Agreement

On August 21/22, 2017, the Founders, Expedia Lodging Partner Services S.à r.l., trivago GmbH, trivago N.V. 
and certain other Expedia parties entered into a contribution agreement with respect to potential tax liability 
arising out of the Post-IPO merger, which we refer to as the contribution agreement. Following our IPO, we 
requested binding tax rulings from the German tax authorities regarding the tax neutrality to trivago GmbH, 
trivago N.V. and the Founders of the Post-IPO merger. Under the rulings, the German tax authorities have 
taken  the  opinion  that  trivago  GmbH  is  liable  for  an  immaterial  tax  amount.  Under  the  IPO  Structuring 
Agreement, our liability for this amount could be considered an "Adverse Ruling Determination", in which 
case the Post-IPO merger would only be consummated if we and Expedia Lodging Partner Services S.à r.l. 
entered into an agreement with Expedia Lodging Partner Services S.à r.l. that would make trivago GmbH 
whole for any additional tax liability incurred by it as a result of the Post-IPO merger. Under the contribution 
agreement, Expedia Lodging Partner Services S.à r.l. undertook, subject to the occurrence of a final, non-
appealable and unchangeable tax assessment notice issued to us, to make an informal immaterial capital 
contribution (informele kapitaalstorting) on the Class B shares in cash in the amount of any (a) German 
Corporate Income Tax (Körperschaftsteuer), (b) German solidarity surcharge (Solidaritätszuschlag) thereon, 
and (c) German Trade Tax (Gewerbesteuer) that would not be made in exchange for any shares issued by 
us. In accordance with the terms and conditions of the contribution agreement, we and Expedia Lodging 
Partner  Services  S.à  r.l.  acknowledged  that  this  contribution  would  be  treated  as  share  premium  (agio) 
attached to the Class B shares and that the amount of this contribution would be attributed to our share 
premium reserve (agioreserve) attached to the Class B shares. The parties to the contribution agreement 
agreed that this contribution by Expedia Lodging Partner Services S.à r.l. shall be treated as a tax neutral 
shareholder contribution (verdeckte Einlage) at the trivago N.V. level for corporate tax purposes to the greatest 
extent  possible.  If  and  to  the  extent  that  German  tax  authorities  challenge  the  neutral  treatment  of  the 
contribution amount at the trivago N.V. level for corporate tax purposes, Expedia Lodging Partner Services 
S.à r.l. will contribute to us, in addition to the contribution amount referenced above, such additional amount 
as is necessary to ensure that the net amount actually received by us (after taking into account the payment 
by us of corporate taxes imposed on the contribution amount and any additional amounts payable to us 
pursuant the requiring payment of such additional amounts) that equals the full amount that we would have 
received had no such corporate taxes been imposed on the contribution amount.

Credit facility Guarantee 

On September 5, 2014, we entered into an uncommitted credit facility with Bank of America Merrill Lynch 
International Ltd., one of the underwriters of our IPO, with a maximum principal amount of €10.0  million. 
Advances under this facility bear interest at a rate of LIBOR plus 1.0% per annum. This facility may be 
terminated  at  any  time  by  the  lender.  Our  obligations  under  this  facility  are  guaranteed  by  Expedia.  On 
December 19, 2014, we entered into an amendment to this facility pursuant to which the maximum principal 
amount was increased to €50.0  million. We utilized €20.0  million of our €50.0  million credit facility to fund 
capital requirements in 2015. During the year ended December 31, 2016, we utilized an additional €20.0 
million  under  our  credit  facility,  and  subsequently  repaid  a  total  of  €40.0  million  of  this  obligation. As  of 
December 31, 2016 and 2017, €0.0  million was drawn from our €50.0  million credit facility.

Lease Guarantee 

On July 23, 2015, we entered into a Lease Agreement with Jupiter EINHUNDERTVIERUNDFÜNFZIG GmbH 
(now IMMOFINANZ Medienhafen GmbH) for office space in the Media Harbour area in Düsseldorf with a 
monthly rent of €566,560.  The initial lease term is for ten years starting with handover of the location scheduled 
for May 2018, and we have the option to extend the lease term for another ten years. Initially, our obligations 
under this lease agreement were guaranteed by Expedia. With effect as of July 2017, the parent guarantee 
was replaced by a bank guarantee.

Loans from Expedia 

In  2014,  Expedia  granted  a  loan  of  €1.0  million  to  the  company  in  conjunction  with  our  acquisition  of 
Rheinfabrik in 2014. We repaid the loan during 2015. 

104

In connection with the exercise of certain employee options, we paid employees’ personal tax liability related 
to the option exercise collateralized by the underlying shares and to be repaid by employees from 2016 
liquidation proceeds. As the proceeds of €7.1  million were funded by Expedia, we recognized a related party 
payable for this amount as of December 31, 2015. The €7.1  million related party payable and the €7.1  million 
shareholder  loan  receivable,  netted  within  the  members’  liability  balance,  was  extinguished  due  to cash 
withheld from proceeds paid to employees by Expedia as part of this call right exercised by Expedia. See 
Note  10—Share-based  awards  and  other  equity  instruments  in  the  notes  to  our  consolidated  financial 
statements. 

Services Agreement 

On May 1, 2013, we entered into an Asset Purchase Agreement, pursuant to which Expedia purchased 
certain computer hardware and software from us, and a Data Hosting Services Agreement, pursuant to which 
Expedia provides us with certain data hosting services relating to all of the servers we use that are located 
within the United States. Either party may terminate the Data Hosting Services Agreement upon 30 days’ 
prior written notice. We have not incurred material expenses under this agreement. 

Services and Support Agreement 

On September 1, 2016, we entered into a Services and Support Agreement, pursuant to which Expedia 
agreed to provide us with certain services in connection with localizing content on our websites, such as 
translation services. Either party may terminate the Services and Support Agreement upon 90 days’ prior 
notice. We have not incurred material expenses under this agreement. 

Commercial relationships 

We currently have commercial relationships with many Expedia affiliated brands, including Brand Expedia, 
Hotels.com, Orbitz, Travelocity, Wotif, HomeAway and ebookers. These are arrangements terminable at will 
or upon three to seven days’ prior notice by either party and on customary commercial terms that enable 
Expedia’s brands to advertise on our platform, and we receive payment for users we refer to them. We are 
also party to a letter agreement pursuant to which Expedia refers traffic to us when a particular hotel or 
region is unavailable on the applicable Expedia website. For the years ended December 31, 2015, 2016 
and 2017, Expedia and its brands accounted for 39%, 36% and 36% of our total revenues, respectively.

See “Item 5 Operating and financial review and prospects” for additional information.

Shared services arrangements 

Pursuant to certain informal shared services arrangements, we have recorded expenses incurred by Expedia 
on behalf of us as a non-cash charge and treated as a contribution from parent in equity. This shared services 
fee, which is comprised of allocations from Expedia for legal, tax, treasury, audit and corporate development 
costs and also includes an allocation of employee compensation within these functions in certain instances. 
These allocations were determined on a basis that we and Expedia considered to be a reasonable, including 
number of factors such as headcount, estimated time spent, and operating expenses and is a reflection of 
the cost of services provided or the benefit received by us. It is not practicable to determine the amounts of 
these expenses that would have been incurred had we operated as an unaffiliated entity, and in the opinion 
of our management, the allocation method is reasonable. For the years ended December 31, 2015, 2016 
and 2017, the shared service fee was €2.8  million, € 4.2 million and €0.5  million, respectively. 

Future agreements with Expedia 

Pursuant to our articles of association, resolutions of the management board to enter into or complete future 
agreements with Expedia require approval by the general meeting of shareholders. Pursuant to the Amended 
and Restated Shareholders’ Agreement, Expedia and the Founders have agreed that such resolutions of 
the general meeting of shareholders require consent of at least one of the Founders. 

105

Employee loans 

In the third quarter of 2015, certain employees exercised stock options, and Expedia Lodging Partner Services 
S.à r.l.  advanced  to  each  option  holder  employee  involved  in  the  exercise  amounts  equivalent  to  such 
employee’s personal tax liability related to the option exercise by issuing loans. Such loans were collateralized 
by the underlying shares and were repaid by employees from 2016 liquidation event proceeds. In the second 
quarter of 2017, trivago GmbH advanced additional loans to two employees to cover their personal tax liability 
relating to their exercise of options. Such loans are collateralized by the underlying shares, and will be repaid 
from liquidation proceeds. 

See Note 10—Share-based awards and other equity instruments in the notes to our consolidated financial 
statements.

Practices—Supervisory board member services agreements.” 

Indemnification agreements 

We  have  entered  into  indemnification  agreements  with  members  of  our  management  board  and  our 
supervisory board. Our articles of association require us to indemnify our management board members and 
supervisory board members to the fullest extent permitted by law.

Item 8: Financial information

A. Consolidated statements and other financial information

See the financial statements beginning on page F-1. 

Legal Proceedings 

From time to time, we may be involved in various claims and legal proceedings relating to claims arising out 
of our operations.

The Australian Competition and Consumer Commission, or ACCC, has requested information and documents 
from us relating to our advertisements in Australia concerning the hotel prices available on our Australian 
site and our strike-through pricing practice, which is the display adjacent to the price quote in the top position 
in our search results of a higher price that is crossed out. We submitted this information to the ACCC in 
February 2018, and plan to provide  certain related  documents in  March 2018. The matter is in its  early 
stages, and we are unable to estimate its potential effect on our financial position and results of operations.

trivago N.V. and certain of its management board members are the subject of two purported class actions, 
filed in the United States District Court for the Southern District of New York following the announcement by 
the U.K. Competition and Markets Authority of its industry-wide investigation into online hotel booking sites, 
asserting claims under the Exchange Act and the Securities Act on behalf of persons who purchased or 
otherwise acquired trivago’s American Depositary  Receipts pursuant  and/or traceable to the registration 
statement and prospectus issued in connection with our IPO on or about December 16, 2016 and/or on the 
open  market  between  December  16,  2016  and  October  27,  2017.  One  of  the  complaints  also  named 
underwriters of our IPO as defendants. On January 22, 2018, the court appointed the lead plaintiff and lead 
counsel in the actions, and they now have the opportunity to file an amended complaint. The matter is in its 
early  stages,  and  we  are  unable  to  estimate  its  potential  effect  on  our  financial  position  and  results  of 
operations.

While it is too early for us to form any view on the likely outcomes of these actions, their outcomes could 
have a material adverse effect on our business, financial condition or results of operations.

Dividends 

We do not at present plan to pay cash dividends on our Class A shares. Under Dutch law, we may only pay 
dividends to the extent that our shareholders’ equity (eigen vermogen) exceeds the sum of the paid-up and 
called-up share capital plus the reserves required to be maintained under Dutch law or by our articles of 
association. Subject to such restrictions, any future determination to pay dividends will be at the discretion 
of our management board (in some instances, subject to approval by a Founder), and will depend upon a 
number  of  factors,  including  our  results  of  operations,  financial  condition,  future  prospects,  contractual 
restrictions, restrictions imposed by applicable law and other factors our management board deems relevant.

Our shareholders adopted the Articles of Association filed as Exhibit 3.1 to our Registration Statement on 
Form F-1 filed with the SEC on November 14, 2016. 

The information set forth in our prospectus dated December 16, 2016, filed with the SEC pursuant to Rule 
424(b), under the headings “Description of share capital and articles of association—Amendment of articles

There are no governmental laws, decrees or regulations in the Netherlands, the Company's jurisdiction of 
organization, that restrict the Company's export or import of capital in any material respect, including, but 
not limited to, foreign exchange controls.

There are no limitations imposed by Dutch law or the Company's charter documents on the right of non-
resident or foreign owners to hold or vote Class A shares.

E. Taxation

The  following  summary  contains  a  description  of  material  German,  Dutch  and  U.S.  federal  income  tax 
consequences  of  the  acquisition,  ownership  and  disposition  of  ADSs,  but  it  does  not  purport  to  be  a 
comprehensive description of all the tax considerations that may be relevant to a decision to purchase ADSs. 
The summary is based on the tax laws of Germany and the regulations thereunder, on the tax laws of the 
Netherlands and regulations thereunder and on the tax laws of the United States and regulations thereunder 
as of the date hereof, which are subject to change. 

German taxation 

The following section presents a number of key German taxation principles which are or can be relevant to 
the acquisition, holding or transfer of ADSs both by an ADS holder (an individual, a partnership or corporation) 
that has a tax domicile in Germany (that is, whose place of residence, habitual abode, registered office or 
place of management is in Germany) not being subject to a specific or special German tax regime and by 
an ADS holder without a tax domicile in Germany. The information is not exhaustive and does not constitute 
a  definitive  explanation  of  all  possible  aspects  of  taxation  that  could  be  relevant  for ADS  holders.  The 
information is based on the tax law in force in Germany as of the date of this annual report (and its interpretation 
by administrative directives and courts) as well as typical provisions of double taxation treaties that Germany 

110

has concluded with other countries. Tax law can change, sometimes retrospectively. Moreover, it cannot be 
ruled out that the German tax authorities or courts may consider an alternative assessment to be correct 
that differs from the one described in this section. 

This section cannot serve as a substitute for tailored tax advice to individual ADS holders. ADS holders are 
therefore advised to consult their tax advisers regarding the tax implications of the acquisition, holding or 
transfer of ADSs and regarding the procedures to be followed to achieve a possible reimbursement of German 
withholding tax (Kapitalertragsteuer). Only such advisors are in a position to take the specific tax-relevant 
circumstances of individual ADS holders into due account. 

Taxation of the company (trivago N.V.) 

General 

tax 

liability 

for  German  corporate 

The  company,  trivago  N.V.,  has  six  German  tax  resident  individuals  serving  as  managing  directors  and 
intends to operate its business from Germany. It is therefore our German tax counsel’s understanding that 
the effective place of management of trivago N.V. should be in Germany, and that trivago N.V. is subject to 
unlimited 
tax 
(Gewerbesteuer) notwithstanding the fact that it is incorporated in the Netherlands as described in “-Tax 
treatment of corporate reorganization.” Nevertheless, the effective place of management test depends upon 
facts and circumstances. The company intends to have its effective place of management in Germany and 
has  made  arrangements  that  are  aimed  to  keep  its  effective  place  of  management  in  Germany.  The 
organizational rules provide that, subject to certain exemptions, (a) management decisions are to be taken 
in principle in Germany and (b) supervisory board meetings shall be held in Germany. In accordance with 
the  organizational  rules  the  Supervisory  Board  has  issued  to  the  Management  Board  “Best-Practice 
Guidelines” giving recommendations on how to deal with certain aspects of the management of the company 
to ensure a German place of management of the company. 

(Körperschaftsteuer)  and 

income 

trade 

tax 

The rate of the corporate income tax is a standard 15% for both distributed and retained earnings, plus a 
solidarity  surcharge  (Solidaritätszuschlag)  amounting  to  5.5%  on  the  corporate  income  tax  liability  (i.e., 
15.825% in total). 

Unless there is a specific exception, dividends (Dividenden) or other profit shares that the company derived 
from domestic or foreign corporations are effectively 95% exempt from corporate income tax, as 5% of such 
receipts are treated as non-deductible business expenses, and are therefore subject to corporate income 
tax (and solidarity surcharge). One of the exceptions applies to dividends that the company receives or 
received from domestic or foreign corporations (since February 28, 2013), being subject to corporate income 
tax (including solidarity surcharge thereon), if the company holds a direct participation of less than 10% in 
the share capital of such corporation at the beginning of the calendar year (hereinafter in all cases, a “Portfolio 
Participation” -Streubesitzbeteiligung). Participations of at least 10% acquired during a calendar year are 
deemed to have been acquired at the beginning of the calendar year. Participations in the share capital of 
other  corporations  which  the  company  holds  through  a  partnership  (including  those  that  are  co-
entrepreneurships (Mitunternehmerschaften)) are attributable to the company only on a pro rata basis at the 
ratio of the interest share of the company in the assets of relevant partnership. 

The company’s gains from the disposal of shares in a domestic or foreign corporation are effectively 95% 
exempt from corporate income tax (including solidarity surcharge thereon), regardless of the size of the 
participation and the holding period. 5% of the gains are treated as non-deductible business expenses and 
are  therefore  subject  to  corporate  income  tax  (plus  solidarity  surcharge  thereon)  at  a  rate  of  15.825%. 
Conversely, losses incurred from the disposal of such shares are not deductible for corporate income tax 
purposes. Currently, there are no specific rules for the taxation of gains arising from the disposal of Portfolio 
Participations. 

The  company  is  subject  to German  trade  tax  (Gewerbesteuer)  with  respect  to  its  taxable  trade  profit 
(Gewerbeertrag)  generated  at  its  permanent  establishments  maintained  in  Germany  (inländische 
Betriebstätte). Depending on the municipal trade tax multiplier applied by the relevant municipal authority 
(Hebesatz), in most cases trade tax ranges from approximately 7% to 18.2% of the taxable trade profit. 

111

When determining the income of the corporation that is subject to corporate income tax, trade tax must not 
be deducted as a business expense. In principle, profits derived from the sale of shares in another domestic 
and foreign corporation are treated in the same way for trade tax purposes as for corporate income tax 
purposes. Contrary to this, profit shares derived from domestic and foreign corporations are only effectively 
95% exempt from trade tax, if the company either held an interest of at least 15% in the share capital of the 
company making the distribution at the beginning of the relevant assessment period (Erhebungszeitraum) 
or-in the case of foreign corporations-if the company has held a stake of this size since the beginning of 
such period and provided that certain further requirements are fulfilled (trade tax participation exemption 
privilege - gewerbesteuerliches Schachtelprivileg). If the participation is held in a foreign corporation as per 
Article 2 of Council Directive 2011/96/EU of November 30, 2011, or the Parent-Subsidiary Directive, with its 
registered  office  in  another  member  state  of  the  European  Union,  the  trade  tax  participation  exemption 
privilege becomes applicable from an interest of 10% in the share capital of the foreign corporation at the 
beginning of the relevant assessment period (Erhebungszeitraum). Otherwise, the profit shares will be subject 
to trade tax in full. Additional restrictions apply for profit shares originating from foreign corporations which 
do not fall under Article 2 of the Parent-Subsidiary Directive. 

The provisions of the so-called interest barrier (Zinsschranke) limit the degree to which interest expenses 
are deductible from the tax base. As a rule, interest expenses exceeding interest income are deductible in 
an amount of up to 30% of the EBITDA as determined for tax purposes in a given financial year, although 
there are exceptions to this rule. Non-deductible interest expenses must be carried forward to subsequent 
financial years. EBITDA that has not been fully utilized can under certain circumstances be carried forward 
and may be considered within the limitations as set out above over the following five years. For trade tax 
purposes, in principle 25% of the interest expenses deductible after applying the interest barrier are added 
back when calculating the taxable trade profit. Therefore, for trade tax purposes, the amount of deductible 
interest expenses is in principle only 75% of the interest expenses deductible for purposes of corporate 
income tax. 

Under certain conditions, negative income of the company that has not been offset against current year 
positive  income  can  be  carried  forward  or  back  into  other  assessment  periods.  Loss  carry-backs  to  the 
immediately preceding assessment period are only permissible up to € 1,000,000 for corporate income tax 
but not at all for trade tax purposes. Negative income not offset against positive income for corporate income 
and trade tax purposes can be carried forward to following taxation periods (tax loss carry-forward). If in 
such following taxation period the taxable income or the taxable trade profit exceeds the € 1,000,000 threshold 
(up to which such income can be offset with the tax loss carry forward in full), only 60% of the excess amount 
can be offset by tax loss carry-forwards. The remaining 40% of the taxable income is subject to tax in any 
case (minimum taxation - Mindestbesteuerung). Unused tax loss carry-forwards can, as a rule, be carried 
forward indefinitely and deducted pursuant to the rules set out regarding future taxable income or trade 
income.  However,  if  more  than  25%  or  more  than  50%  of  the  company’s  share  capital  or  voting  rights 
respectively is/are transferred to a purchaser or group of purchasers within five years, directly or indirectly, 
or if a similar situation arises (harmful share acquisition - schädlicher Beteiligungserwerb), the company’s 
unutilized losses and interest carry-forwards (possibly also EBITDA carry-forwards) will be forfeited in part 
(in case of the transfer of a participation of more than 25% but no more than 50%) or in full (in case of the 
transfer of a participation of more than 50%) and cannot be offset against future profits, unless one of the 
specific exceptions under section 8c or 8d of the German Corporate Income Tax Act applies.

Expenses incurred by trivago N.V. in connection with our IPO may be regarded as incurred for the benefit 
of the Founders. In such case, the tax authorities may take the view to treat such expenses as not deductible 
for tax purposes and assess withholding tax at a rate of 26.375% on the respective amounts. 

Tax treatment of corporate reorganization 

Following  our  IPO,  we  requested  binding  tax  rulings  from  the  German  tax  authorities  regarding  the  tax 
neutrality to trivago GmbH, trivago N.V. and the Founders of our plan to merge trivago GmbH into and with 
trivago N.V., which we refer to as the post-IPO merger. Based on the facts presented in the requests for the 
tax rulings, the tax rulings confirmed the tax neutrality of the post-IPO merger for trivago GmbH, trivago N.V. 

112

 
and the Founders under German tax law in all material respects. Following receipt of such tax rulings, we 
consummated the post-IPO merger, which became legally effective as of September 7, 2017. However, for 
income tax purposes the post-IPO merger has to be treated with retroactive effect as of December 31, 2016. 
Pursuant to the post-IPO merger, the Founders exchanged all of their units of trivago GmbH remaining after 
the pre-IPO corporate reorganization for Class B shares of trivago N.V. 

German taxation of ADS holders 

General 

Based on the interpretation circular (Besteuerung von American Depository 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 the ADR Tax Circular, for German tax purposes, ADRs 
referring  to  shares  issued  by  a  German  stock  corporation  (Aktiengesellschaft)  represent  a  beneficial 
ownership interest in the underlying ordinary shares. 

The  ADSs  should  qualify  as  ADRs  under  the  ADR  Tax  Circular,  and  dividends  would  accordingly  be 
attributable to the holders of the ADSs for German tax purposes as if they would hold Class A shares, and 
not to the legal owner of the underlying Class A shares (which is the depositary holding the Class A shares 
for the ADS holders). Therefore, the ADS holders should, for German tax purposes, be treated as directly 
holding an interest in the company’s Class A shares. With respect to German tax risks with respect to the 
ADSs please refer to “Item 3 D. Risk factors” above. 

Income tax implications of the holding, sale and transfer of ADSs 

In terms of the income taxation of ADS holders, a distinction must be made between taxation in connection 
with the holding of ADSs (“German taxation of the distributions from ADSs”) and taxation in connection with 
the sale of ADSs (“German taxation of capital gains from ADSs”). 

German taxation of the distributions from ADSs 

Withholding tax-General 

The  full  amount  of  a  dividend  distributed  by  the  company  is  subject  to  German  withholding  tax 
(Kapitalertragsteuer) at a rate of 25% plus a solidarity surcharge of 5.5% on the withholding tax, resulting 
in an aggregate tax rate of 26.375%. This, however, will not apply if and to the extent that dividend payments 
are funded from the company’s contribution account for tax purposes (steuerliches Einlagekonto; Section 27 
of the German Corporate Income Tax Act (Körperschaftsteuergesetz, or KStG)); in this case, no withholding 
tax will be withheld. The basis for the withholding tax is the dividend approved for distribution by the company’s 
shareholders’ meeting. The amount of the relevant taxable income is based on the gross amount in euro; 
any currency differences should be irrelevant. 

In  general,  withholding  tax  on  dividends  distributed  by  a  company  to  its  shareholders  is  withheld  and 
discharged for the account of the shareholders by the company. However, if and when shares are admitted 
for collective custody by a securities custodian bank (Wertpapiersammelbank) pursuant to Section 5 of the 
German Act on Securities Accounts (Depotgesetz) and are entrusted to such bank for collective custody 
(Sammelverwahrung)  in  Germany,  the  withholding  tax  is  withheld  and  passed  on  for  the  account  of  the 
shareholders  by  the  domestic  credit  or  financial  services  institution  (inländisches  Kredit-  oder 
Finanzdienstleistungsinstitut) (including domestic branches of such foreign enterprises), by the domestic 
securities trading company (inländisches Wertpapierhandelsunternehmen) or the domestic securities trading 
bank (inländische Wertpapierhandelsbank) which keeps or administers the shares and disburses or credits 
the dividends or disburses the dividends to a foreign agent or by the central securities depository to which 
the shares were entrusted for collective custody if the dividends are disbursed to a foreign agent by such 
central securities depository, each a Paying Agent. The company in which shares are held does not assume 
any responsibility for the withholding of the withholding tax. In general, the withholding tax must be withheld 
regardless of whether and to which extent the distribution is exempt from tax at the level of a shareholder 
and whether the shareholder is domiciled in Germany or abroad. 

113

As  the ADS  holders  should,  for  German  tax  purposes,  be  treated  as  directly  holding  an  interest  in  the 
company’s Class A shares, the description in the paragraph above should apply accordingly. 

More specifically as regards to the distributions from ADSs, the German withholding tax will be withheld 
either by (i) the German financial institution that holds or administers the underlying Class A shares in custody 
and disburses or credits the dividend income from the underlying Class A shares or (ii) the German collective 
securities custodian, i.e., on the payment made to the depositary (in both cases (i) or (ii), a Paying Agent). 
Further, a withholding tax certificate should be issued which entitles the addressee of such certificate to a 
refund or tax credit of the German taxes withheld. The ADS holder should be entitled to the refund or tax 
credit (and not the legal owner which is the depositary) as it is treated for German tax purposes as the 
beneficial owner of the Class A shares. Consequently, the German taxes levied on the payments under the 
ADSs should be the same as if the ADS holder invested directly in the Class A shares because the ADS 
holder is either entitled to a refund or a tax credit. The ADS holders would be treated as if they hold Class A 
shares directly and withholding tax would be charged only once. 

Taxation of the distributions from ADSs for investors not domiciled in Germany 

ADS  holders  without  a  tax  domicile  in  Germany  whose ADSs  are  attributable  to  a  German  permanent 
establishment or fixed place of business or are part of business assets for which a permanent representative 
in Germany has been appointed, are also subject to tax in Germany on their dividend income. In this respect, 
the provisions outlined below for ADS holders with a tax domicile in Germany whose ADS are held as business 
assets apply accordingly (“-Taxation of the distributions from ADSs for investors domiciled in Germany-ADSs 
held as business  assets”). The  withholding  tax  (including  the solidarity  surcharge  thereon)  withheld  and 
passed on will be credited against the income or corporate income tax liability or refunded in the amount of 
any excess. 

In all other cases, ADS holders are only subject to German taxation with respect to specific German source 
income (beschränkte Steuerpflicht), in particular, dividends distributed by a German tax resident corporation. 
Dividend payments that are funded from the company’s contribution account for tax purposes (steuerliches 
Einlagekonto;  Section 27  KStG)  are  not  taxable  in  Germany  (provided  the  respective  certification 
requirements are properly fulfilled). According to the ADR Tax Circular, dividend income from the underlying 
shares should be attributed to the holder of the ADSs for German tax purposes and not to the legal owner 
of the shares. As a consequence thereof, dividend income derived from ADSs should be treated as German 
source income (beschränkte Steuerpflicht). 

Any  German  limited  tax  liability  on  dividends  is  discharged  by  withholding  tax.  Withholding  tax  is  only 
reimbursed in the cases and to the extent described below. 

However, withholding tax on dividends distributed to an ADS holder being a company domiciled in another 
EU Member State within the meaning of Article 2 of the Parent-Subsidiary Directive may be refunded or 
exempted upon application and subject to further conditions. This also applies to dividends distributed to a 
permanent  establishment  in  another  EU  Member  State  of  such  a  parent  company  or  to  a  permanent 
establishment in another EU Member State of a parent company that is subject to unlimited tax liability in 
Germany,  provided  that  the  participation  in  the  company  actually  forms  part  of  such  permanent 
establishment’s business assets. As further requirements for a refund or exemption of withholding tax under 
the Parent-Subsidiary Directive, the ADS holder needs to hold ADSs that represent at least a 10% direct 
stake in the company’s registered capital for one year and to file a respective application with the German 
Federal Central Tax Office (Bundeszentralamt für Steuern, Hauptdienstsitz Bonn-Beuel, An der Küppe 1, 
53225 Bonn) using an official form. 

Based on the double taxation treaty concluded between Germany and the jurisdiction where an investor is 
tax resident for purposes of the respective double taxation treaty, which we refer to in the following as the 
Treaty, German withholding tax may be reduced to a lower tax rate usually amounting to 15% of the gross 
dividend on the basis of an applicable Treaty. In this event, the excess of the total withholding tax, including 
the solidarity surcharge, over the maximum rate of withholding tax permitted by the Treaty should be refunded 
to the investors upon application. A U.S. investor for example initially should receive a net payment of € 73.625 

114

 
from a gross dividend amounting to € 100 (i.e., € 100 minus the 26.375% withholding tax). Such U.S. investor 
may, subject to fulfilling procedural requirements, be entitled to a partial refund from the German tax authorities 
in  the  amount  of  11.375%  of  the  gross  dividend. As  a  result,  the  U.S.  investor  may  ultimately  receive  a 
payment of € 85 in total (85% of the gross dividend amount), provided that it is entitled to Treaty benefits. 

On December 1, 2016, the German Federal Parliament (Bundestag) approved a new provision (section 50j 
EStG) to limit the entitlement of non-resident shareholders to a refund or a reduction of German dividend 
withholding tax under a double taxation treaty under certain circumstances. The new rule came into force 
for assessment periods starting January 1, 2017. Under the new rule, a refund or a reduction of German 
dividend withholding tax under a double taxation treaty will, in principle, only be granted, if (i) the non-resident 
ADS holder is not obliged to forward the dividend proceeds received from the company to any other person, 
the non-resident shareholder has continuously held beneficial ownership in the shares of the company during 
the 45-day period prior to the due date of the distribution (Pre-Holding Period), the non-resident shareholder 
continuously holds beneficial ownership in the shares of the company during the 45-day period after the due 
date of the distribution (Post-Holding Period), and the non-resident shareholder has continuously borne the 
market risk exposure during both the Pre-Holding Period and the Post-Holding Period, taking hedging or 
comparable transaction into account. On the other hand, the new rule shall not apply (and the entitlement 
of a non-resident ADS holder to a refund or a reduction of German dividend withholding tax is not limited by 
this rule), if (i) the applicable double taxation treaty of the non-resident shareholder provides for a withholding 
tax  rate  of  at  least  15%,  or  (ii)  the  non-resident ADS  holder  is  subject  to  income  taxation  in  its  state  of 
residency (without being tax exempt) and holds directly at least 10% in the share capital of the company 
paying  the  dividend  or  (iii)  the  non-resident  ADS  holder  has  continuously  been  holding  the  beneficial 
ownership in the shares of the company for a period of at least twelve months prior to the date on which the 
income accrued (Zufluss). 

Investors should note that the aforementioned refund or reduction of German withholding tax under a Treaty 
requires the investor to make tax filings with the competent German tax office using a withholding tax certificate 
issued  under  German  law  by  the  agent,  who  has  withheld  and  remitted  the  withholding  tax  (the  Paying 
Agent). If the depositary operates an interface with DTC, it should have under regular circumstances sufficient 
information about the identity of the ADS holder so that a tax reclaim process can be filed with the competent 
German tax office and a withholding tax certificate can be issued to the ADS holder. In the absence of such 
withholding tax certificate, an ADS holder will not be entitled to receive a tax refund from the German tax 
authorities and may not credit the German withholding tax against its tax liability. 

Claims for refunds may be made on a separate form, which must be filed with the German Federal Central 
Tax Office (Bundeszentralamt für Steuern, An der Küppe 1, 53225 Bonn, Germany). The form is available 
at the same address, on the German Federal Central Tax Office’s website (www.bzst.de) or from embassies 
of the Federal Republic of Germany. The refund claim becomes time-barred after four years following the 
calendar year in which the dividend is received unless the commencement starts later, the period is interrupted 
or  suspended. As  described  above,  an  investor  must  submit  to  the  German  tax  authorities  the  original 
withholding tax certificate (or a certified copy thereof) issued by the Paying Agent and documenting the tax 
withheld. Furthermore, an official certification of tax residency must be submitted. 

Under a simplified refund procedure based on electronic data exchange (Datenträgerverfahren), a paying 
or disbursing agent that is registered as a participant in the electronic data exchange procedure with the 
German Federal Central Tax Office (Bundeszentralamt für Steuern) may file an electronic collective refund 
claim on behalf of all of the ADS holders for whom it holds the company’s ADSs in custody. However, the 
simplified refund procedure only allows for a refund up to the regular tax rate provided in the Treaty. It is not 
possible  to  use  the  simplified  refund  procedure  to  claim  a  further  refund,  for  example  based  on  special 
privileges under a Treaty. 

If dividends are distributed to corporations subject to a limited tax liability in Germany, i.e. corporations with 
no statutory seat or place of management in Germany, and if the shares neither belong to the assets of a 
permanent establishment or fixed place of business in Germany nor form part of business assets for which 
a permanent representative in Germany has been appointed, two-fifths of the tax withheld at the source can 
be, subject to national anti-treaty shopping provisions, refunded even if the prerequisites for a refund under 

115

the Parent-Subsidiary Directive or the relevant Treaty are not fulfilled. The relevant application forms are 
available at the German Federal Central Tax Office at the address specified above. 

The exemption from withholding tax under the Parent-Subsidiary Directive as well as the aforementioned 
possibilities for a refund of withholding tax depend on certain other conditions being met (particularly the 
fulfillment of so-called substance requirements-Substanzerfordernisse). 

Taxation of the distributions from ADSs for investors domiciled in Germany 

Based on the assumption that the ADS holder should be treated, in line with the ADR Tax Circular, as the 
beneficial owner of the Class A shares for German tax purposes, German ADS holders should be subject 
to German taxation as if they owned the Class A shares directly. 

ADSs held as non-business assets 

Dividends distributed to ADS holders with a tax domicile in Germany whose ADSs are held as non-business 
assets form part of their taxable capital investment income, which is subject to a flat tax at a rate of 25% 
plus solidarity surcharge of 5.5% thereon (i.e. 26.375% in total plus church tax, if applicable). The income 
tax owed for this dividend income is in general discharged by the withholding tax levied by the company (flat 
tax-Abgeltungsteuer) unless the ADS holder applies for the regular, progressive tax rate. Income-related 
expenses cannot be deducted from the capital investment income, except for an annual lump-sum deduction 
(Sparer-Pauschbetrag) of € 801 (€ 1,602 for married couples and for partners in accordance with the registered 
partnership law (Gesetz über die Eingetragene Lebenspartnerschaft) filing jointly). However, the ADS holder 
may request that its capital investment income (including dividends) along with its other taxable income is 
taxed at the progressive income tax rate (instead of the flat tax on capital investment income) if this results 
in  a  lower  tax  burden  (Günstigerprüfung).  In  this  case,  the  withholding  tax  will  be  credited  against  the 
progressive income tax and any excess amount will be refunded. Pursuant to the view of the German tax 
authorities (which has been confirmed by a decision by the German Federal Tax Court (Bundesfinanzhof)), 
in this case as well, income-related expenses cannot be deducted from the capital investment income, except 
for the aforementioned annual lump-sum deduction. 

Exceptions from the flat tax apply upon application for ADS holders with underlying shares of at least 25% 
in the company and for ADS holders with underlying shares of at least 1% in the company and who work for 
the company in a professional capacity. 

With regard to dividends received after December 31, 2014, an automatic procedure for deducting church 
tax applies unless the ADS holder has filed a blocking notice (Sperrvermerk) with the German Federal Central 
Tax Office. The church tax payable on the dividend is withheld and passed on by the Paying Agent. In this 
case, the church tax for dividends is satisfied by the Paying Agent withholding such tax. Church tax withheld 
at source may not be deducted as a special expense (Sonderausgabe) in the course of the tax assessment, 
but the Paying Agent may reduce the withholding tax (including the solidarity surcharge) by 26.375% of the 
church tax to be withheld on the dividends. If the ADS holder has filed a blocking notice and no church tax 
is withheld by a Paying Agent, an ADS holder subject to church tax is obliged to declare the dividends in his 
income tax return. The church tax on the dividends is then levied by way of a tax assessment. 

As  an  exemption,  dividend  payments  that  are  funded  from  the  company’s  contribution  account  for  tax 
purposes (steuerliches Einlagekonto; Section 27 KStG) and are paid to ADS holders with a tax domicile in 
Germany with ADSs held as non-business assets, do, contrary to the above, not form part of the ADS holder’s 
taxable  income  (provided  the  respective  certification  requirements  are  properly  fulfilled).  If  the  dividend 
payment  funded  from  the  company’s  contribution  account  for  tax  purposes  (steuerliches  Einlagekonto; 
Section 27 KStG) exceeds the ADS holder’s acquisition costs, negative acquisition costs will arise which 
can result in a higher capital gain in case of the ADSs’ or shares’ disposal. This will not apply if (i) the ADS 
holder or, in the event of a gratuitous transfer, its legal predecessor, or, if the ADSs have been gratuitously 
transferred several times in succession, one of his legal predecessors at any point during the five years 
preceding the (deemed, as the case may be) disposal, directly or indirectly held ADSs (and/or shares) that 
represent at least 1% of the underlying share capital of the company (a “Qualified Holding”), and (ii) the 
dividend  payment  funded  from  the  company’s  contribution  account  for  tax  purposes  (steuerliches 

116

Einlagekonto; Section 27 KStG) exceeds the acquisition costs of the ADSs. In such a case of a Qualified 
Holding, a dividend payment funded from the company’s contribution account for tax purposes (steuerliches 
Einlagekonto; Section 27 KStG) is deemed a sale of the ADSs and is taxable as a capital gain if and to the 
extent the dividend payment funded from the company’s contribution account for tax purposes (steuerliches 
Einlagekonto;  Section 27  KStG)  exceeds  the  acquisition  costs  of  the ADSs.  In  this  case,  the  taxation 
corresponds with the description in “-German taxation of capital gains from ADSs-ADS holder with a domicile 
in Germany” made with regard to ADS holders maintaining a Qualified Holding. 

The Paying Agent which keeps or administers the ADSs and pays or credits the capital income is required 
to create so-called pots for the loss set-off (Verlustverrechnungstöpfe) to allow for setting-off of negative 
capital  income  with  current  and  future  positive  capital  income.  A  set  off  of  negative  capital  income 
administrated by one Paying Agent with positive capital income administrated by another Paying Agent is 
not possible and can only be achieved in the course of the income tax assessment at the level of the respective 
investor. In this case, the taxpayer has to apply for a certificate confirming the amount of losses not offset 
with the Paying Agent where the pots for the loss set off exist. The application is irrevocable and has to reach 
the Paying Agent before December 15th of the respective year; otherwise the losses will be carried forward 
to the following year by the Paying Agent. 

Withholding tax will not be withheld by a Paying Agent if the taxpayer provides the Paying Agent with an 
application for exemption (Freistellungsauftrag) to the extent that the capital income does not exceed the 
annual lump sum allowance (Sparerpauschbetrag) of € 801 (€ 1,602 for married couples and for partners in 
accordance with the registered partnership law (Gesetz über die Eingetragene Lebenspartnerschaft) filing 
jointly) as outlined on the application for exemption. Furthermore, no withholding tax will be levied if the 
taxpayer provides the Paying Agent with a non-assessment certificate (Nichtveranlagungsbescheinigung) 
to be applied for with the competent tax office of the investor. 

ADSs held as business assets 

Dividends from ADSs held as business assets by an ADS holder with a tax domicile in Germany are not 
subject to the flat tax. The taxation depends on whether the ADS holder is a corporation, a sole proprietor 
or a partnership (co-entrepreneurship). The withholding tax (including the solidarity surcharge thereon and 
church tax, if applicable) withheld and paid will be credited against the ADS holder’s income tax or corporate 
income tax liability (including the solidarity surcharge thereon and church tax, if applicable) or refunded in 
the amount of any excess. 

Dividend payments that are funded from the company’s contribution account for tax purposes (steuerliches 
Einlagekonto; Section 27 KStG) and are paid to ADS holders with a tax domicile in Germany whose ADSs 
are held as business assets are fully tax-exempt in the hands of such ADS holder (provided the respective 
certification  requirements  are  properly  fulfilled).  To  the  extent  the  dividend  payments  funded  from  the 
company’s contribution account for tax purposes exceed the acquisition costs of the ADS, a taxable capital 
gain should occur. The taxation of such gain corresponds with the description in “-German taxation of capital 
gains from ADSs” made with regard to ADS holders whose ADSs are held as business assets (however, as 
regards the application of the 95% exemption in case of a corporation this is not undisputed). 

Corporations 

If the ADS holder is a corporation with a tax domicile in Germany, the dividends are effectively 95% exempt 
from corporate income tax and the solidarity surcharge unless an exception is applicable thereto. 5% of the 
dividends are treated as non-deductible business expenses and are therefore subject to corporate income 
tax (plus the solidarity surcharge thereon) at a total tax rate of 15.825%. In other respects, business expenses 
actually incurred in direct relation to the dividends may be deducted. However, dividends are not exempt 
from corporate income tax (including solidarity surcharge thereon), if the ADS holder only held (or holds) a 
direct participation of less than 10% in the underlying share capital of the distributing corporation at the 
beginning of the calendar year (hereinafter in all cases, a “Portfolio Participation” (Streubesitzbeteiligung)). 
Underlying participations of at least 10% acquired during a calendar year are deemed to have been acquired 
at the beginning of the calendar year. Underlying participations that an ADS holder holds through a partnership

(including those that are co-entrepreneurships (Mitunternehmerschaften)) are attributable to the ADS holder 
only on a pro rata basis at the ratio of the interest share of the ADS holder in the assets of the relevant 
partnership. 

However, the dividends (after deducting business expenses economically related to the dividends) are subject 
to trade tax in the full amount, unless the requirements of the trade tax participation exemption privilege are 
fulfilled. In this latter case, the dividends are not subject to trade tax; however, trade tax is levied on amounts 
considered to be non-deductible business expenses (amounting to 5% of the dividend). Depending on the 
municipal trade tax multiplier applied by the relevant municipal authority, in most cases trade tax ranges 
from 7% to approximately 18%. 

Sole proprietors 

If the ADSs are held as business assets by a sole proprietor with a tax domicile in Germany, only 60% of 
the dividends are subject to progressive income tax (plus the solidarity surcharge thereon) at a total tax rate 
of up to approximately 47.5% (plus church tax, if applicable), under the so-called partial income method 
(Teileinkünfteverfahren). Only 60% of the business expenses economically related to the dividends are tax-
deductible. If the ADSs belong to a domestic permanent establishment in Germany of a business operation 
of an ADS holder, the dividend income (after deducting business expenses economically related thereto) is 
fully subject to trade tax, unless the prerequisites of the trade tax participation exemption privilege are fulfilled. 
In this latter case the net amount of dividends, i.e. after deducting directly related expenses, is exempt from 
trade tax. As a rule, trade tax can be credited against the ADS holder’s personal income tax, either in full or 
in part, by means of a lump-sum tax credit method, depending on the level of the municipal trade tax multiplier 
and certain individual tax-relevant circumstances of the taxpayer. 

 Partnerships 

If the ADS holder is a genuine business partnership or a deemed business partnership (co-entrepreneurship) 
with a permanent establishment in Germany, the income tax or corporate income tax is not levied at the 
level of the partnership but at the level of the respective partner. The taxation of every partner depends on 
whether the partner is a corporation or an individual. If the partner is a corporation, the dividends contained 
in the profit share of the partner will be taxed in accordance with the rules applicable for corporations (see 
“Corporations”  above).  If  the  partner  is  an  individual,  the  taxation  follows  the  rules  described  for  sole 
proprietors, (see “Sole proprietors” above). Upon application and subject to further conditions, an individual 
as a partner can have his personal income tax rate reduced for earnings retained at the level of the partnership. 

In addition, the dividends are subject to trade tax in the full amount at the partnership level if the ADSs are 
attributed to a German permanent establishment of the partnership, unless the requirements of the trade 
tax participation exemption privilege are fulfilled. If a partner of the partnership is an individual, the portion 
of the trade tax paid by the partnership pertaining to his profit share will be credited, either in full or in part, 
against his personal income tax by means of a lump-sum method, depending on the level of the municipal 
trade tax multiplier and certain individual tax-relevant circumstances of the taxpayer. Due to a lack of case 
law  and  administrative  guidance,  it  is  currently  unclear  how  the  rules  for  the  taxation  of  dividends  from 
Portfolio Participations (see “Corporations” above) might impact the trade tax treatment at the level of the 
partnership. ADS holders are strongly recommended to consult their tax advisors. Under a literal reading of 
the law, if the partnership qualifies for the trade tax exemption privilege at the beginning of the relevant 
assessment period, the dividends should not be subject to trade tax. However, in this case, trade tax should 
be levied on 5% of the dividends to the extent they are attributable to the profit share of such corporate 
partners to whom at least 10% of the underlying shares in the company are attributable on a look-through 
basis, since such portion of the dividends should be deemed to be non-deductible business expenses. The 
remaining portion of the dividend income attributable to other than such specific corporate partners (which 
includes individual partners and should, under a literal reading of the law, also include corporate partners to 
whom, on a look-through basis, only Portfolio Participations are attributable) should (after the deduction of 
business expenses economically related thereto) not be subject to trade tax.

Special treatment of companies in the financial and insurance sectors and pension funds 

If  financial  institutions  or  financial  services  providers  hold ADSs  that  are  allocable  to  their  trading  book 
pursuant to Section 1a of the German Banking Act (Gesetz über das Kreditwesen), they will neither be able 
to use the partial income method nor have 60% of their dividend income exempt from taxation nor be entitled 
to the effective 95% exemption from corporate income tax plus the solidarity surcharge and any applicable 
trade tax. Thus, dividend income is fully taxable. The same applies to ADSs acquired by financial institutions 
in the meaning of the German Banking Act for the purpose of generating profits from short-term proprietary 
trading. The preceding sentences apply accordingly for ADSs held in a permanent establishment in Germany 
by financial institutions, financial service providers, and finance companies tax resident in another member 
state of the European Union or in other signatory states of the EEA Agreement. Likewise, the tax exemption 
described  earlier  afforded  to  corporations  from ADSs  does  not  apply  to ADSs  that  qualify  as  a  capital 
investment in the case of life insurance and health insurance companies, or those which are held by pension 
funds. However, an exemption to the foregoing, and thus a 95% effective tax exemption, applies to dividends 
obtained by the aforementioned companies, to which the Parent-Subsidiary Directive applies. 

 Withholding tax-ADSs held in a German custody account 

If and when the ADSs are held in a German custody account withholding tax may apply at different levels: 

•  at a first level, there will be German withholding tax of 26.375% (including solidarity surcharge) on trivago 
N.V.’s dividend payment made to the ADS Agent; this withholding tax may be reduced to 15% or to a 
lower tax rate; 

•  at a second level, the German paying agent that holds the ADSs in custody for the investor, or the German 
Distribution Paying Agent, is required to withhold again German withholding tax of 26.375% (including 
solidarity surcharge) plus church tax, if any. The German Distribution Paying Agent is the German domestic 
credit or financial services institution (inländisches Kredit- oder Finanzdienstleistungsinstitut) (including 
German domestic branches of such foreign enterprises), the German domestic securities trading company 
(inländisches  Wertpapierhandelsunternehmen)  or  the  German  domestic  securities  trading  bank 
(inländische Wertpapierhandelsbank) which keeps or administers the ADSs and disburses or credits the 
ADS distributions. 

Consequently, a higher tax burden may arise if the respective withholding tax certificate cannot be issued 
and therefore neither the German investor nor the ADS agent are able to use the withholding tax withheld 
at the first level or the second level as a tax credit or apply for a respective tax refund. The German Federal 
Ministry of Finance (Bundesministerium der Finanzen) has suggested and described a procedural solution 
to avoid such potential double taxation in an interpretation circular dated October 26, 2011 (BMF IV C 1 - S 
2400/11/10002:003). However, from a procedural perspective, it is not entirely clear whether this circular 
also applies to ADSs. According to our German tax counsel’s opinion, this should be the case since ADSs 
are representing the underlying Class A shares (see above). 

Especially if the ADS are not held with a German Distribution Paying Agent, a German investor should be 
required to include any payment from the ADSs in its German tax return and may not be entitled to credit 
taxes withheld at the first or second level against its German tax liability for the reason that the required 
withholding tax certificate has not been issued. 

Further, the refund or credit of the withholding tax may be denied in a portion of three-fifths under certain 
circumstances  as 
Income  Tax  Act 
(Einkommensteuergesetz), inter alia, if and when the ADS holder is not the beneficial owner of the ADSs 
within a time frame of 45 days around the ex-date of the underlying Class A shares. 

in  Section 36a  German 

further  described 

in  more  detail 

German taxation of capital gains from ADS 

Taxation of capital gains from ADSs-ADS holder not tax resident in Germany 

The capital gains from the disposition of ADSs realized by an ADS holder who is not a German tax resident 
should be subject to German tax only if such investor held ADSs that directly or indirectly represent 1% or 

119

more in the underlying company’s ordinary shares (i.e., a Qualified Holding as defined in “—Taxation of the
distributions from ADS for investors domiciled in Germany-ADSs held as non-business assets”) at any time 
during a five year period preceding the disposition or if the ADSs or underlying shares belong to a domestic 
permanent establishment or fixed place of business or are part of business assets for which a permanent 
representative in Germany has been appointed. If such holder had acquired the ADSs without consideration, 
the previous owner’s holding period and amount of the holding would also be taken into account. 

In case of a Qualified Holding, 5% of the gains from the disposal of the ADSs should under German domestic 
tax law currently be subject to corporate income tax plus solidarity surcharge thereon if the ADS holder is a 
corporation. If the ADS holder is an individual, only 60% of the gains from the disposal of the ADSs are 
subject  to  the  progressive  income  tax  rate  plus  solidarity  surcharge  thereon  (partial-income  method). 
However, most Treaties provide for an exemption from German taxation and attribute the right of taxation 
to the ADS holder’s state of residence. According to German tax authorities there is no obligation to levy 
withholding tax at source in the case of a Qualified Holding if the ADS holder submits to the Paying Agent 
a certificate of residence issued by the competent foreign tax authority. 

In case of a Qualified Holding, the relevant ADS holder has to file a German tax return. Please note that a 
tax  return  is  also  required  if  Germany  does  not  have  the  right  to  tax  such  capital  gains  pursuant  to  the 
individual applicable Treaty. 

With regard to capital gains or losses from ADSs attributable to a domestic permanent establishment or fixed 
place of business or which form part of business assets for which a permanent representative in Germany 
has  been  appointed,  the  above-mentioned  provisions  pertaining  to ADS  holders  with  a  tax  domicile  in 
Germany whose ADSs are business assets apply mutatis mutandis (see “Taxation of capital gains from 
ADSs-ADS holder with a domicile in Germany-ADSs held as business assets”). The Paying Agent can refrain 
from deducting the withholding tax if the ADS holder declares to the Paying Agent on an official form that 
the ADSs form part of domestic business assets and certain other requirements are met. 

German statutory law requires the disbursing agent to levy withholding tax on capital gains from the sale of 
ordinary shares or other securities, including ADSs, held in a custodial account in Germany. With regard to 
the  German  taxation  of  capital  gains,  disbursing  agent  means  a  bank,  a  financial  services  institution,  a 
securities  trading  enterprise  or  a  securities  trading  bank  (each  as  defined  in  the  German  Banking Act 
(Kreditwesengesetz) and, in each case including a German branch of a foreign enterprise, but excluding a 
foreign branch of a German enterprise) that holds the ADSs in custody or administers the ADSs for the 
investor or conducts sales or other dispositions and disburses or credits the income from the ADSs to the 
holder of the ADSs. The German statutory law with the exception of ADSs held by an ADS holder holding 
directly or indirectly through ADSs and shares at least 1% in the company’s ordinary share capital, does not 
create a limited tax liability in Germany so that there should be no obligation to withhold taxes on such capital 
gains. Further, it is not entirely clear by the German statutory law whether a withholding should be made if 
and when the (share) ADS holder creates a limited tax liability in Germany with its holding. However, an 
interpretation circular (Einzelfragen zur Abgeltungsteuer) issued by the German Federal Ministry of Finance 
(Bundesministerium der Finanzen) dated January 18, 2016 (reference number IV C 1-S2252/08/10004:017) 
provides that taxes need not to be withheld when the holder of the custody account is not a resident of 
Germany for German tax purposes and the income is not subject to German taxation. The interpretation 
circular further states that there is no obligation to withhold such tax even if the non-resident holder holds 
1% or more of the share capital of a German company through ADSs and shares. As a result, under no 
circumstances should there be an obligation to withhold taxes on capital gains realized by ADS holders not 
tax resident in Germany. Although this circular is not binding on German tax courts, in practice, the disbursing 
agents are required to follow the guidance contained in such interpretation circulars. But even if there is no 
withholding in Germany, the ADS holder is required to make a tax filing with the German tax authorities if 
and when it is subject to a limited tax liability in Germany with its capital gains under German domestic tax 
law. 

120

Taxation of capital gains from ADSs-ADS holder with a domicile in Germany 

The capital gain from the disposition of ADSs realized by an ADS holder who is tax resident in Germany 
should be subject to German tax as if the ADS holder owned the underlying Class A shares directly. This is 
supported by an interpretation circular (Einzelfragen zur Abgeltungsteuer) issued by the German Federal 
Ministry of Finance (Bundesministerium der Finanzen) dated January 18, 2016 (reference number IV C 1-
S2252/08/10004:017) with respect to the limitation on the offsetting of capital loss from ADRs with capital 
gains from shares and/or ADRs and the exchange of the ADRs into the respective (represented) shares. 

ADSs held as non-business assets 

Gains from the disposal of ADSs by an ADS holder with a tax domicile in Germany and held as non-business 
assets are, regardless of the holding period, subject to a flat tax on capital investment income at a rate of 
25% (plus the solidarity surcharge of 5.5% thereon, i.e. 26.375% in total plus any church tax if applicable) 
unless the ADS holder applies for the regular, progressive tax rate regime. 

The taxable capital gain is computed as the difference between (a) the sale proceeds and (b) the acquisition 
costs of the ADS and the expenses related directly and economically to the disposal. Dividend payments 
that  are  funded  from  the  company’s  contribution  account  for  tax  purposes  (steuerliches  Einlagekonto; 
Section 27  KStG)  reduce  the  original  acquisition  costs;  if  dividend  payments  that  are  funded  from  the 
company’s contribution account for tax purposes (steuerliches Einlagekonto; Section 27 KStG) exceed the 
acquisition costs, negative acquisition costs, which can increase a capital gain, can arise in case of ADS 
holders, whose ADS are held as non-business assets and do not qualify as Qualified Holding. 

Only an annual lump-sum deduction of € 801 (€ 1,602 for married couples filing jointly) may be deducted from 
the entire capital investments income. It is not possible to deduct income-related expenses in connection 
with capital gains, except for the expenses directly related in substance to the disposal which can be deducted 
when calculating the capital gains. Losses from disposals of ADSs or shares may only be offset against 
capital gains from the disposal of ADSs or shares. 

If the disposal of the ADSs is executed by a domestic credit institution, domestic financial services institution 
(inländisches Kredit- oder Finanzdienstleistungsinstitut) (including domestic branches of foreign credit and 
(inländisches 
financial 
services 
Wertpapierhandelsunternehmen) 
(inländische 
domestic 
Wertpapierhandelsbank), and such office pays out or credits the capital gains (a Paying Agent), the tax on 
the capital gains will under regular circumstances be discharged for the account of the seller by the Paying 
Agent imposing the withholding tax on investment income at the rate of 26.375% (including the solidarity 
surcharge thereon) on the capital gain.

However, the ADS holder can apply for his total capital investment income together with his other taxable 
income to be subject to his progressive income tax rate as opposed to the flat tax on investment income, if 
this results in a lower tax liability. In this case, the withholding tax is credited against the progressive income 
tax  and  any  resulting  excess  amount  will  be  refunded.  Pursuant  to  the  current  view  of  the  German  tax 
authorities (which has been confirmed by a decision by the German Federal Tax Court (Bundesfinanzhof)), 
in this case as well, income-related expenses cannot be deducted from the capital investment income, except 
for the aforementioned annual lump-sum deduction. Further, the limitations on offsetting losses are also 
applicable under the income tax assessment. 

If the withholding tax or, if applicable, the church tax on capital gains is not withheld by a Paying Agent, the 
ADS holder is required to declare the capital gains in his income tax return. The income tax and any applicable 
church tax on the capital gains will then be collected by way of assessment. 

An automatic procedure for deducting church tax applies unless the ADS holder has filed a blocking notice 
(Sperrvermerk) with the German Federal Central Tax Office; church tax on capital gains is then withheld by 
the Paying Agent and is deemed to have been paid when the tax is deducted. A deduction of the withheld 
church tax as a special expense is not permissible, but the withholding tax to be withheld (including the 
solidarity surcharge) is reduced by 26.375% of the church tax to be withheld on the capital gains. 

121

 
Regardless of the holding period and the time of acquisition, gains from the disposal of ADSs are not subject 
to the flat tax but to progressive income tax if an ADS holder domiciled in Germany, or, in the event of a 
munificent transfer, their legal predecessor, or, if the ADSs have been munificently transferred several times 
in succession, one of his legal predecessors at any point during the five years preceding the disposal, directly 
or indirectly held ADSs (and/or shares) that represent at least 1% of the underlying share capital of the 
company (i.e., a Qualified Holding). In this case the partial income method applies to gains from the disposal 
of ADSs, which means that only 60% of the capital gains are subject to tax and only 60% of the losses on 
the disposal and expenses economically related thereto are tax deductible. Even though withholding tax has 
to be withheld by a Paying Agent in the case of a Qualified Holding, this does not discharge the tax liability 
of the ADS holder. Consequently, an ADS holder must declare his capital gains in his income tax return. The 
withholding tax (including the solidarity surcharge thereon and church tax, if applicable) levied and paid will 
be credited against the ADS holder’s income tax liability as assessed (including the solidarity surcharge 
thereon and any church tax if applicable) or refunded in the amount of any excess. 

ADSs held as business assets 

Gains from the sale of ADSs held as business assets of an ADS holder with a tax domicile in Germany are 
not subject to the flat tax. The taxation of the capital gains depends on whether the ADS holder is a corporation, 
a sole proprietor or a partnership (co-entrepreneurship). 

Corporations 

If the ADS holder is a corporation with a tax domicile in Germany, the gains from the disposal of ADSs are, 
effectively 95% exempt from corporate income tax (including the solidarity surcharge thereon) and trade tax, 
regardless of the size of the participation and the holding period unless an exception is applicable thereto. 5% 
of the gains are treated as non-deductible business expenses and are therefore subject to corporate income 
tax (plus the solidarity surcharge thereon) at a rate of 15.825% and trade tax (depending on the municipal 
trade tax multiplier applied by the municipal authority, in most cases between 7% and approximately 18%). 
As a rule, capital losses and other profit reductions in connection with ADSs (e.g. from a write-down) cannot 
be deducted for tax purposes. Currently, there are no specific rules for the taxation of gains arising from the 
disposal of Portfolio Participations. 

Sole proprietors 

If the ADSs are held as business assets by a sole proprietor with a tax domicile in Germany, only 60% of 
the gains from the disposal of the ADSs are subject to progressive income tax (plus the solidarity surcharge 
thereon)  at  a  total  tax  rate  of  up  to  approximately  47.5%,  and,  if  applicable,  church  tax  (partial-income 
method).  Only  60%  of  the  losses  on  the  disposal  and  expenses  economically  related  thereto  are  tax 
deductible. If the ADSs belong to a German permanent establishment of a business operation of the sole 
proprietor, 60% of the gains of the disposal of the ADSs are, in addition, subject to trade tax. 

Trade tax 

Trade tax can be credited against the ADS holder’s personal income tax liability, either in full or in part, by 
means of a lump-sum tax credit method-depending on the level of the municipal trade tax multiplier and 
certain individual tax-relevant circumstances of the taxpayer. 

Partnerships 

If the ADS holder is a genuine business partnership or a deemed business partnership (co-entrepreneurship) 
with a permanent establishment in Germany, the income or corporate income tax is not levied at the level 
of the partnership but at the level of the respective partner. The taxation depends on whether the partner is 
a corporation or an individual. If the partner is a corporation, the capital gains from the ADSs as contained 
in the profit share of the partner will be taxed in accordance with the rules applicable to corporations (see 
“Corporations” above). For capital gains in the profit share of a partner that is an individual, the principles 
outlined  above  for  sole  proprietors  apply  accordingly  (partial-income  method,  see  above  under  “Sole 

122

proprietors”). Upon application and subject to further conditions, an individual as a partner can obtain a 
reduction of his personal income tax rate for earnings retained at the level of the partnership. 

In addition, capital gains from the ADSs are subject to trade tax at the level of the partnership if the ADSs 
are attributed to a domestic permanent establishment of a business operation of the partnership, (i) at 60% 
as far as they are attributable to the profit share of an individual as the partner of the partnership, and, 
(ii) currently, at 5% as far as they are attributable to the profit share of a corporation as the partner of the 
partnership. Capital losses and other profit reductions in connection with the ADSs are currently not deductible 
for trade tax purposes if they are attributable to the profit share of a corporation; however, 60% of the capital 
losses are deductible subject to general limitations to the extent such losses are attributable to the profit 
share of an individual. 

If the partner of the partnership is an individual, the portion of the trade tax paid by the partnership attributable 
to his profit share will be credited, either in full or in part, against his personal income tax by means of a 
lump-sum method, depending on the level of the municipal trade tax multiplier and certain individual tax-
relevant circumstances of the taxpayer. 

Special treatment of companies in the financial and insurance sectors and pension funds 

If financial institutions or financial services providers sell ADSs that are allocable to their trading book pursuant 
to Section 1a of the German Banking Act (Gesetz über das Kreditwesen), they will neither be able to use 
the partial income method nor have 60% of their gains exempted from taxation nor be entitled to the effective 
95% exemption from corporate income tax plus the solidarity surcharge and any applicable trade tax. Thus, 
capital gains are fully taxable. The same applies to ADSs acquired by financial institutions in the meaning 
of the German Banking Act for the purpose of generating profits from short-term proprietary trading. The 
preceding sentences apply accordingly for ADSs held in a permanent establishment in Germany by financial 
institutions, financial service providers, and finance companies tax resident in another member state of the 
European Union or in other signatory states of the EEA Agreement or the ADSs reflect at least 1% of the 
share capital of the company. Likewise, the tax exemption described earlier afforded to corporations for 
dividend income and capital gains from the sale of ADSs does not apply to ADSs that qualify as a capital 
investment in the case of life insurance and health insurance companies, or those which are held by pension 
funds.

tax, if applicable, at the rate of 26.375% (including the solidarity surcharge) plus church tax, if any, on the 
capital gains for the account of the seller will be withheld by the Paying Agent. No withholding tax should 
become due, however, if the investor held directly or indirectly 1% or more in the share capital of the company 
through ADSs and/or shares at any time during a five year period preceding the disposition. In this event, 
the relevant investor has to file a German tax return.

In case of a Paying Agent, capital gains from ADSs held as business assets are not subject to withholding 
tax in the same way as ADSs held as non-business assets by an ADS holder (see “-Taxation of capital gains 
from ADSs-ADS holder with a domicile in Germany-ADSs held as non-business assets”). Instead, the Paying 
Agent will not levy the withholding tax, provided that (i) the ADS holder is a corporation, association of persons 
or estate with a tax domicile in Germany, or (ii) the ADSs belong to the domestic business assets of an ADS 
holder, and the ADS holder declares so to the Paying Agent using the designated official form and certain 
other requirements are met. If withholding tax is imposed by a Paying Agent, the withholding tax (including 
the solidarity surcharge thereon and church tax, if applicable) imposed and discharged will be credited against 
the income tax or corporate income tax liability (including the solidarity surcharge thereon and church tax, 
if applicable) or will be refunded in the amount of any excess. 

123

 
Taxation of capital gains from ADSs-Class A shares in exchange of the ADSs 

An ADS holder may request from the issuer of the ADSs to receive the Class A shares in exchange for the 
ADSs. This kind of exchange should not be qualified as a sale of the ADSs followed by an acquisition of the 
Class A shares, because ADSs should represent a beneficial ownership interest in the underlying shares 
and the holders of ADSs should for German tax purposes be treated as if they held the shares directly (please 
refer to “Item 3 D. Risk factors” above). This treatment is supported by an interpretation circular (Einzelfragen 
zur Abgeltungsteuer) issued by the German Federal Ministry of Finance (Bundesministerium der Finanzen) 
dated January 18, 2016 (reference number IV C 1-S2252/08/10004:017). The income taxation of Class A 
shares follows the same basic principles as described for the ADSs. 

German inheritance and gift tax 

It is unclear whether the German inheritance or gift tax applies to the transfer of ADSs, as the ADR Tax 
Circular  does  not  refer  explicitly  to  the  German  Inheritance  and  Gift  Tax  Act  (“Erbschaftsteuer-  und 
Schenkungsteuergesetz”).  However,  if  German  inheritance  or  gift  tax  is  applicable  to ADSs,  then  under 
German law, this transfer would be subject to German gift or inheritance tax if: 

(a) the decedent or donor or heir, beneficiary or other transferee (i) maintained his or her residence or a 
habitual abode in Germany or had its place of management or registered office in Germany at the time of 
the transfer, or (ii) is a German citizen who has spent no more than five consecutive years outside Germany 
without maintaining a residence in Germany or (iii) is a German citizen who serves for a German entity 
established under public law and is remunerated for his or her service from German public funds (including 
family members who form part of such person’s household, if they are German citizens) and is only subject 
to estate or inheritance tax in his or her country of residence or habitual abode with respect to assets located 
in such country (special rules apply to certain former German citizens who neither maintain a residence nor 
have their habitual abode in Germany), or 

(b) at the time of the transfer, the ADSs are held by the decedent or donor as business assets forming part 
of a permanent establishment in Germany or for which a permanent representative in Germany has been 
appointed, or 

(c) the ADSs subject to such transfer form part of a portfolio that represents at the time of the transfer 10% 
or more of the registered share capital of the company and that has been held directly or indirectly by the 
decedent or donor, either alone or together with related persons. 

Generally, the transferee may be subject to inheritance or gift tax in Germany and in the jurisdiction where 
he or she is tax resident if such jurisdiction levies such kind of tax. There are only limited treaties that intend 
to avoid the potential double taxation. Under the treaty between the Federal Republic of Germany and the 
United States of America for the avoidance of double taxation with respect to taxes on inheritances and gifts 
(Abkommen  zwischen  der  Bundesrepublik  Deutschland  und  den  Vereinigten  Staaten  von  Amerika  zur 
Vermeidung der Doppelbesteuerung auf dem Gebiet der Nachlass-, Erbschaft- und Schenkungsteuern in 
der Fassung vom 21. Dezember 2000), or the United States-Germany Inheritance and Gifts Tax Treaty, and 
assuming that this treaty applies to ADSs, a transfer of ADSs by gift or upon death is not subject to German 
inheritance or gift tax if the donor or the transferor is domiciled in the United States within the meaning of 
the United States-Germany Inheritance and Gift Tax Treaty and is neither a citizen of Germany nor a former 
citizen of Germany and, at the time of the transfer, the ADSs are not held by the decedent or donor as 
business  assets  forming  part  of  a  permanent  establishment  in  Germany  or  for  which  a  permanent 
representative in Germany has been appointed. Notwithstanding the foregoing, in case the heir, transferee 
or other beneficiary (i) has, at the time of the transfer, his or her residence or habitual abode in Germany, or 
(ii) is a German citizen who has spent no more than five (or, in certain circumstances, ten) consecutive years 
outside Germany without maintaining a residence in Germany or (iii) is a German citizen who serves for a 
German entity established under public law and is remunerated for his or her service from German public 
funds (including family members who form part of such person’s household, if they are German citizens) 
and is only subject to estate or inheritance tax in his or her country of residence or habitual abode with 
respect to assets located in such country (or special rules apply to certain former German citizens who 

124

neither maintain a residence nor have their habitual abode in Germany), the transferred ADSs are subject 
to German inheritance or gift tax. 

If, in this case, Germany levies inheritance or gift tax on the ADSs with reference to the heir’s, transferee’s 
or other beneficiary’s residence in Germany or his or her German citizenship, and the United States also 
levies federal estate tax or federal gift tax with reference to the decedent’s or donor’s residence (but not with 
reference to the decedent’s or donor’s citizenship), the amount of the U.S. federal estate tax or the U.S. 
federal gift tax, respectively, paid in the United States with respect to the transferred ADSs is credited against 
the German inheritance or gift tax liability, provided the U.S. federal estate tax or the U.S. federal gift tax, 
as the case may be, does not exceed the part of the German inheritance or gift tax, as computed before the 
credit is given, which is attributable to the transferred ADSs. A claim for credit of the U.S. federal estate tax 
or the U.S. federal gift tax, as the case may be, may be made within one year of the final determination 
(administrative or judicial) and payment of the U.S. federal estate tax or the U.S. federal gift tax, as the case 
may be, provided that the determination and payment are made within ten years of the date of death of the 
decedent or of the date of the making of the gift by the donor. Similarly, U.S. state-level estate or gift tax is 
also creditable against the German inheritance or gift tax liability to the extent that U.S. federal estate or gift 
tax is creditable. 

Other German taxes 

There are no transfer, stamp or similar taxes which would apply to the purchase, sale or other disposition 
of ADSs in Germany. Further, no value added tax is currently levied on the purchase or disposal or other 
forms of transfer of the ADSs; however, an entrepreneur may opt to subject disposals of ADSs, which are 
in principle exempt from value added tax, to value added tax if the sale is made to another entrepreneur for 
the entrepreneur’s business. Net worth tax (Vermögensteuer) is currently not levied in Germany. It is still 
unclear and not yet decided whether Germany, based on a potential EU Directive, will introduce a Financial 
Transaction Tax. 

Material Netherlands tax considerations 

General 

The following is a summary of material Netherlands tax consequences of the acquisition, holding and disposal 
of our ADSs or Class A shares. This summary does not purport to describe all possible tax considerations 
or consequences that may be relevant to a holder or prospective holder of our ADSs or Class A shares and 
does not purport to deal with the tax consequences applicable to all categories of investors, some of which 
may be subject to special treatment under applicable law (such as trusts or other arrangements). In view of 
its general nature, it should be treated with corresponding caution. To the extent this summary relates to 
legal conclusions under current Netherlands tax law, and subject to the qualifications it contains, it represents 
the opinion of NautaDutilh N.V., our special Dutch counsel. Holders should consult with their tax advisors 
with  regard  to  the  tax  consequences  of  investing  in  the  ADSs  or  Class  A  shares  in  their  particular 
circumstances. The discussion below is included for general information purposes only. For purposes of 
Dutch tax law, a holder of ADSs or Class A shares may include an individual or entity who does not have 
the legal title of these ADSs or Class A shares, but to whom nevertheless the ADSs or Class A shares or the 
income thereof is attributed based on specific statutory provisions or on the basis of such individual or entity 
having an interest in the ADSs or Class A shares or the income thereof.

Please note that this summary does not describe the tax considerations for: 

(i) holders of ADSs or Class A shares if such holders, and in the case of individuals, his or her partner or 
certain of their relatives by blood or marriage in the direct line (including foster children), have a substantial 
interest (aanmerkelijk belang) or deemed substantial interest (fictief aanmerkelijk belang) in us under the 
Netherlands Income Tax Act 2001 (Wet inkomstenbelasting 2001). A holder of securities in a company is 
considered to hold a substantial interest in such company if such holder alone or, in the case of individuals, 
together with his/her partner (as defined in the Netherlands Income Tax Act 2001), directly or indirectly holds 
(i) an interest of 5% or more of the total issued and outstanding capital of that company or of 5% or more of 

125

the issued and outstanding capital of a certain class of shares of that company; or (ii) rights to acquire, 
directly or indirectly, such interest; or (iii) certain profit sharing rights in that company that relate to 5% or 
more of the company’s annual profits and/or to 5% or more of the company’s liquidation proceeds. A deemed 
substantial interest may arise if a substantial interest (or part thereof) in a company has been disposed of, 
or is deemed to have been disposed of, on a non-recognition basis; 

(ii) a holder of ADSs or Class A shares that is not an individual for which its shareholdings qualify or qualified 
as a participation (deelneming) for purposes of the Netherlands Corporate Income Tax Act 1969 (Wet op de 
vennootschapsbelasting 1969). A taxpayer’s shareholding of 5% or more in a company’s nominal paid-up 
share capital qualifies as a participation. A holder may also have a participation if such holder does not have 
a shareholding of 5% or more but a related entity (statutorily defined term) has a participation or if the company 
in which the shares are held is a related entity (statutorily defined term); 

(iii) holders of ADSs or Class A shares who are individuals for whom the ADSs or Class A shares or any 
benefit derived from the ADSs or Class A shares are a remuneration or deemed to be a remuneration for 
(employment) activities performed by such holders or certain individuals related to such holders (as defined 
in the Netherlands Income Tax Act 2001); and

(iv) pension funds, investment institutions (fiscale beleggingsinstellingen), exempt investment institutions 
(vrijgestelde beleggingsinstellingen) and other entities that are, in whole or in part, not subject to or exempt 
from corporate income tax in the Netherlands, as well as entities that are exempt from corporate income tax 
in their country of residence, such country of residence being another state of the European Union, Norway, 
Liechtenstein, Iceland or any other state with which the Netherlands have agreed to exchange information 
in line with international standards. 

Except  as  otherwise  indicated,  this  summary  only  addresses  Netherlands  national  tax  legislation  and 
published  regulations,  whereby  the  Netherlands  and  Dutch  law  means  the  part  of  the  Kingdom  of  the 
Netherlands located in Europe and its law respectively, as in effect on the date hereof and as interpreted in 
published case law until this date as available in printed form, without prejudice to any amendment introduced 
(or to become effective) at a later date and/or implemented with or without retroactive effect. The applicable 
tax laws or interpretations thereof may change, or the relevant facts and circumstances may change, and 
such changes may affect the contents of this section, which will not be updated to reflect any such changes. 

Dividend withholding tax 

We are required to withhold Dutch dividend withholding tax at a rate of 15% from dividends distributed by 
us (which withholding tax will not be borne by us, but will be withheld by us from the gross dividends paid 
on the Class A shares). However, as long as we continue to have our place of management in Germany, 
and  not  in  the  Netherlands,  under  the  Convention  between  the  Federal  Republic  of  Germany  and  the 
Netherlands  for  the  avoidance  of  double  taxation  with  respect  to  taxes  on  income  of  2012,  we  will  be 
considered  to  be  exclusively  tax  resident  in  Germany  and  we  should  not  be  required  to  withhold  Dutch 
dividend withholding tax. This exemption from withholding does not apply to dividends distributed by us to 
a holder who is resident or deemed to be resident in the Netherlands for Dutch income tax purposes or Dutch 
corporation tax purposes or to holders of ADSs or Class A shares that are neither resident nor deemed to 
be resident of the Netherlands if the ADSs or Class A shares are attributable to a Netherlands permanent 
establishment of such non-resident holder, in which events the following applies. See “Item 3 D. Risk factors
—If we pay dividends, we may need to withhold tax on such dividends in both Germany and the Netherlands.” 

Dividends distributed by us to individuals and corporate legal entities who are resident or deemed to be 
resident  in  the  Netherlands  for  Netherlands  tax  purposes  (“Netherlands  Resident  Individuals”  and 
“Netherlands Resident Entities” as the case may be) or to holders of ADSs or Class A shares that are neither 
resident nor deemed to be resident of the Netherlands if the ADSs or Class A shares are attributable to a 
Netherlands  permanent  establishment  of  such  non-resident  holder  are  subject  to  Netherlands  dividend 
withholding tax at a rate of 15%. The expression “dividends distributed” includes, among other things: 

•  distributions in cash or in kind, deemed and constructive distributions and repayments of paid-in capital 

not recognized for Netherlands dividend withholding tax purposes; 

126

 
• 

liquidation proceeds, proceeds of redemption of Class A shares, or proceeds of the repurchase of Class 
A shares by us or one of our subsidiaries or other affiliated entities to the extent such proceeds exceed 
the average paid-in capital of those Class A shares as recognized for purposes of Netherlands dividend 
withholding tax, unless, in case of a repurchase, a particular statutory exemption applies; 

•  an amount equal to the par value of Class A shares issued or an increase of the par value of Class A 
shares, to the extent that it does not appear that a contribution, recognized for purposes of Netherlands 
dividend withholding tax, has been made or will be made; and 

•  partial repayment of the paid-in capital, recognized for purposes of Netherlands dividend withholding tax, 
if and to the extent that we have net profits (zuivere winst), unless the holders of Class A shares have 
resolved in advance at a general meeting to make such repayment and the par value of the Class A shares 
concerned has been reduced by an equal amount by way of an amendment of our articles of association. 

Netherlands Resident Individuals and Netherlands Resident Entities can generally credit the Netherlands 
dividend withholding tax against their income tax or corporate income tax liability. The same applies to holders 
of ADSs or Class A shares that are neither resident nor deemed to be resident of the Netherlands if the ADSs 
or Class A shares are attributable to a Netherlands permanent establishment of such non-resident holder. 

Pursuant  to  legislation  to  counteract  "dividend  stripping",  a  reduction,  exemption,  credit  or  refund  of 
Netherlands dividend withholding tax is denied if the recipient of the dividend is not the beneficial owner as 
described in the Netherlands Dividend Withholding Tax Act 1965 (Wet op de dividendbelasting 1965). This 
legislation targets situations in which a shareholder retains its economic interest in shares but reduces the 
withholding tax costs on dividends by a transaction with another party. It is not required for these rules to 
apply  that  the  recipient  of  the  dividends  is  aware  that  a  dividend  stripping  transaction  took  place.  The 
Netherlands  State  Secretary  of  Finance  takes  the  position  that  the  definition  of  beneficial  ownership 
introduced by this legislation will also apply in the context of a double taxation convention. 

Taxes on income and capital gains 

Netherlands Resident Individuals 

If a holder of ADSs or Class A shares is a Netherlands Resident Individual, any benefit derived or deemed 
to be derived from the ADSs or Class A shares is taxable at the progressive income tax rates (with a maximum 
of 52%, rate for 2018), if: 

(a) 

(b) 

the ADSs or Class A shares are attributable to an enterprise from which the Netherlands Resident 
Individual derives a share of the profit, whether as an entrepreneur (ondernemer) or as a person who 
has a co-entitlement to the net worth (medegerechtigd tot het vermogen) of such enterprise, without 
being an entrepreneur or a shareholder in such enterprise, as defined in the Netherlands Income Tax 
Act 2001; or 

the holder of the ADSs or Class A shares is considered to perform activities with respect to the ADSs 
or Class A shares that go beyond ordinary asset management (normaal, actief vermogensbeheer) or 
derives benefits from the ADSs or Class A shares that are taxable as benefits from other activities 
(resultaat uit overige werkzaamheden). 

If the above-mentioned conditions (a) and (b) do not apply to the individual holder of ADSs or Class A shares, 
such holder will be taxed annually on a deemed, variable return (with a maximum of 5.38% in 2018) of his 
or her net investment assets for the year at an income tax rate of 30%. The net investment assets for the 
year are the fair market value of the investment assets less the allowable liabilities  on 1 January of the 
relevant calendar year. The ADSs or Class A shares are included as investment assets. A tax-free allowance 
may  be  available. Actual  benefits  derived  from  the ADSs  or  Class A  shares  are  as  such  not  subject  to 
Netherlands income tax. 

For the net investment assets on January 1, 2018, a deemed return between 2.02% and 5.38% (depending 
on the amount of such net investment assets on January 2018) will be applied. The deemed, variable return 
will be adjusted annually on the basis of historic market yields. 

127

Netherlands Resident Entities 

Any benefit derived or deemed to be derived from the ADSs or Class A shares held by Netherlands Resident 
Entities, including any capital gains realized on the disposal thereof, will be subject to Netherlands corporate 
income tax at a rate of 20% with respect to taxable profits up to €200,000  and 25% with respect to taxable 
profits in excess of that amount (rates and brackets for 2018).

Non-residents of the Netherlands 

A holder of ADSs or Class A shares that is neither a Netherlands Resident Entity nor a Netherlands Resident 
Individual will not be subject to Netherlands taxes on income or on capital gains in respect of any payment 
under ADSs or the Class A shares or any gain realized on the disposal or deemed disposal of the ADSs or 
Class A shares, provided that: 

 (i) 

(ii) 

such  holder  does  not  have  an  interest  in  an  enterprise  or  a  deemed  enterprise  (as  defined  in  the 
Netherlands Income Tax Act 2001 and the Netherlands Corporate Income Tax Act 1969) which, in whole 
or  in  part,  is  either  effectively  managed  in  the  Netherlands  or  carried  on  through  a  permanent 
establishment, a deemed permanent establishment or a permanent representative in the Netherlands 
and to which enterprise or part of an enterprise the ADSs or Class A shares are attributable; and 

in the event the holder is an individual, such holder does not carry out any activities in the Netherlands 
with respect to the ADSs or Class A shares that go beyond ordinary asset management and does not 
derive benefits from the ADSs or Class A shares that are taxable as benefits from other activities in the 
Netherlands. 

Gift and inheritance taxes 

Residents of the Netherlands 

Gift or inheritance taxes will arise in the Netherlands with respect to a transfer of the ADSs or Class A shares 
by way of a gift by, or on the death of, a holder of ADSs or Class A shares who is resident or deemed to be 
resident in the Netherlands at the time of the gift or his/her death. 

Non-residents of the Netherlands 

No gift or inheritance taxes will arise in the Netherlands with respect to a transfer of the ADSs or Class A 
shares by way of gift by, or on the death of, a holder of ADSs or Class A shares who is neither resident nor 
deemed to be resident in the Netherlands, unless: 

(i) 

in the case of a gift of ADSs or Class A shares by an individual who at the date of the gift was neither 
resident nor deemed to be resident in the Netherlands, such individual dies within 180 days after the 
date of the gift, while being resident or deemed to be resident of the Netherlands; or 

(ii) 

the transfer is otherwise construed as a gift or inheritance made by, or on behalf of, a person who, at 
the time of the gift or death, is or is deemed to be resident of the Netherlands. 

For purposes of Netherlands gift and inheritance taxes, amongst others, a person that holds the Netherlands 
nationality  will  be  deemed  to  be  resident  of  the  Netherlands  if  such  person  has  been  resident  in  the 
Netherlands at any time during the ten years preceding the date of the gift or his or her death. Additionally, 
for purposes of Netherlands gift tax, amongst others, a person not holding the Netherlands nationality will 
be deemed to be resident of the Netherlands if such person has been resident in the Netherlands at any 
time during the twelve months preceding the date of the gift. Applicable tax treaties may override deemed 
residency. 

Other taxes and duties 

No Netherlands value added tax (omzetbelasting) and no Netherlands registration tax, stamp duty or any 
other similar documentary tax or duty will be payable by a holder of ADSs or Class A shares on any payment 
in  consideration  for  the  acquisition,  ownership  or  disposal  of  the ADSs  or  Class A  shares  (other  than  a 

128

payment for financial services that are not exempt from Netherlands value added tax and that are rendered 
to the holder of ADSs or Class A shares that is resident in Netherlands for Netherlands tax purposes). 

Material U.S. federal income tax considerations 

The following is a discussion of the material U.S. federal income tax consequences to U.S. Holders (as 
defined below) under present law of the ownership and disposition of our ADSs. Other than the discussion 
relating to whether we qualify as a PFIC, and subject to the qualifications contained herein, the discussion 
below of U.S. federal income tax laws and the legal conclusions with respect thereto represents the opinion 
of Latham & Watkins LLP, our special U.S. counsel. This discussion applies only to U.S. Holders that acquire 
ADSs in this offering, hold such ADSs as “capital assets” (within the meaning of Section 1221 of the Code) 
and that have the U.S. dollar as their functional currency. This discussion is based on the Internal Revenue 
Code of 1986, as amended, the Code, the U.S. Treasury regulations promulgated thereunder, administrative 
rulings of the IRS and judicial decisions, each as in effect as of the date hereof. All of the foregoing authorities 
are subject to change or differing interpretations, possibly with retroactive effect, and any such change or 
differing interpretation could affect the tax consequences described below. This discussion does not purport 
to be a complete analysis or listing of all potential U.S. federal income tax considerations that may be relevant 
to holders with respect to their ownership and disposition of ADSs. Accordingly, it is not intended to be, and 
should not be construed as, tax advice. This summary does not address any consequences under any U.S. 
federal tax laws other than those pertaining to the income tax (e.g., estate or gift taxes), any alternative 
minimum  tax  consequences,  any  consequences  under  the  Medicare  tax  imposed  at  3.8%  on  certain 
investment income, any withholding required pursuant to the Foreign Account Tax Compliance Act of 2010 
(including the U.S. Treasury regulations promulgated thereunder and intergovernmental agreements entered 
into in connection therewith) or any state, local or non-U.S. tax consequences. 

The following discussion also does not address U.S. federal income tax consequences that may be relevant 
to a U.S. Holder in light of such holder’s particular circumstances or to U.S. Holders subject to special rules 
under the U.S. federal income tax laws such as: 

•  banks and other financial institutions; 

• 

• 

regulated investment companies, real estate investment trusts and grantor trusts; 

insurance companies; 

•  broker-dealers; 

• 

• 

traders in securities that elect to mark to market; 

tax-exempt entities or any individual retirement account or Roth IRA as defined in Sections 408 and 408A 
of the Code, respectively; 

•  U.S. expatriates; 

•  persons holding our ADSs as part of a straddle, hedging, constructive sale, conversion or other integrated 

transaction; 

•  persons that actually or constructively own 10% or more of the voting power or value of our stock; 

•  persons that are resident or ordinarily resident in or have a permanent establishment in a jurisdiction 

outside the United States or persons that are not U.S. Holders (as defined below); 

•  persons subject to special tax accounting rules as a result of any item of gross income with respect to 

our ADSs being taken into account in an applicable financial statement; 

•  persons who acquired our ADSs pursuant to the exercise of any employee share option or otherwise as 

compensation; or 

•  partnerships or other pass-through entities or arrangements treated as such (or persons holding our ADSs 

through partnerships or other pass-through entities or arrangements treated as such). 

129

PROSPECTIVE  PURCHASERS  ARE  URGED  TO  CONSULT  THEIR  TAX  ADVISORS  ABOUT  THE 
APPLICATION OF THE U.S. FEDERAL TAX RULES TO THEIR PARTICULAR CIRCUMSTANCES AS 
WELL AS THE STATE, LOCAL AND NON-U.S. TAX CONSEQUENCES TO THEM OF THE PURCHASE, 
OWNERSHIP AND DISPOSITION OF OUR ADSS. 

For purposes of this discussion, a “U.S. Holder” is a beneficial owner of an ADS that is, for U.S. federal 
income tax purposes: 

•  an individual who is a citizen or resident of the United States; 

•  a corporation (or other entity taxable as a corporation) created or organized under the laws of the United 

States, any state thereof or the District of Columbia; 

•  an estate whose income is subject to U.S. federal income taxation regardless of its source; or 

•  a trust if (1) the administration of the trust is subject to the primary supervision of a court within the United 
States and one or more U.S. persons have authority to control all substantial decisions of the trust, or 
(2) a valid election is in effect under applicable U.S. Treasury regulations to treat the trust as a U.S. person. 

The tax treatment of a partner in a partnership or other entity or arrangement taxable as a partnership for 
U.S. federal income tax purposes that holds our ADSs will depend on such partner’s status and the activities 
of the partnership. 

The discussion below assumes the representations contained in the deposit agreement are true and that 
the obligations in the deposit agreement and any related agreement have been and will be complied with in 
accordance with their terms. For U.S. federal income tax purposes, a U.S. Holder of ADSs should be treated 
as the beneficial owner of the underlying Class A shares represented by the ADSs. Accordingly, no gain or 
loss should be recognized if a U.S. Holder exchanges ADSs for the underlying shares represented by those 
ADSs. 

The U.S. Treasury has expressed concerns that intermediaries in the chain of ownership between the holder 
of an ADS and the issuer of the security underlying the ADS may be taking actions that are inconsistent with 
the beneficial ownership of the underlying security. Accordingly, the creditability of any foreign taxes paid 
and the availability of the reduced tax rate for dividends received by certain non-corporate U.S. Holders, 
including individual U.S. Holders (as discussed below), could be affected by actions taken by intermediaries 
in the chain of ownership between the holders of ADSs and us if as a result of such actions the holders of 
ADSs are not properly treated as beneficial owners of underlying Class A shares. 

Distributions 

Subject to the passive foreign investment company, or PFIC, rules discussed below, the gross amount of 
distributions made with respect to our ADSs (including the amount of any foreign taxes withheld therefrom, 
if any, and excluding certain pro rata distributions of our Class A Shares or other similar equity interests) will 
be includable in a U.S. Holder’s gross income, in accordance with such U.S. Holder’s method of accounting 
for U.S. federal income tax purposes, as dividend income, to the extent that such distributions are paid out 
of our current or accumulated earnings and profits as determined under U.S. federal income tax principles. 
So  long  as  we  do  not  compute  earnings  and  profits  under  U.S.  federal  income  tax  principles,  all  such 
distributions made with respect to our ADSs should be treated as dividends. Dividends on our ADSs will not 
be eligible for the dividends-received deduction allowed under the Code to U.S. Holders that are corporations. 

With  respect  to  non-corporate  U.S.  Holders,  dividends  on  our ADSs  may  qualify  as  “qualified  dividend 
income,” which is eligible for reduced rates of taxation provided that (1) we are eligible for the benefits of 
the income tax treaty between the United States and the federal republic of Germany or with respect to any 
dividend paid on ADSs which are readily tradable on an established securities market in the United States, 
(2) we are not a PFIC (as discussed below) for either the taxable year in which the dividend was paid or the 
preceding taxable year, (3) the U.S. Holder satisfies certain holding period requirements, and (4) the U.S. 
Holder is not under an obligation to make related payments with respect to positions in substantially similar 
or related property. U.S. Holders should consult their tax advisors regarding the availability of the lower rate 

130

 
for dividends paid with respect to our ADSs. Our ADSs are listed on Nasdaq, which is an established securities 
market in the United States. The ADSs should be considered readily tradable on Nasdaq. However, there 
can be no assurance that the ADSs will be considered readily tradable on an established securities market 
in the United States in later years. 

The amount of any distribution on our ADSs paid in foreign currency will be equal to the U.S. dollar value of 
such currency on the date such distribution is includible in income by the recipient, regardless of whether 
the payment is in fact converted into U.S. dollars at that time. The amount of any distribution of property 
other than cash will be the fair market value of such property on the date of distribution. 

Sale or other taxable disposition of our ADSs 

Subject to the PFIC rules discussed below, upon a sale or other taxable disposition of ADSs, a U.S. Holder 
will recognize a capital gain or loss for U.S. federal income tax purposes in an amount equal to the difference 
between the amount realized on such disposition and such U.S. Holder’s adjusted tax basis in such ADSs. 
Any such gain or loss will be treated as long-term capital gain or loss if the U.S. Holder’s holding period for 
such ADSs exceeds one year. Non-corporate U.S. Holders (including individuals) are currently subject to 
U.S. federal income tax on long-term capital gain at preferential rates. The deductibility of capital losses is 
subject to significant limitations. 

If the consideration received for our ADSs is paid in foreign currency, the amount realized will be the U.S. 
dollar value of the payment received translated at the spot rate of exchange on the date of disposition. If our 
ADSs are treated as traded on an established securities market and the relevant U.S. Holder is either a cash 
basis  taxpayer  or  an  accrual  basis  taxpayer  who  has  made  a  special  election  (which  must  be  applied 
consistently from year to year and cannot be changed without the consent of the Internal Revenue Service), 
such holder will determine the U.S. dollar value of the amount realized in a foreign currency by translating 
the amount received at the spot rate of exchange on the settlement date of the sale. If our ADSs are not 
treated as traded on an established securities market, or the relevant U.S. Holder is an accrual basis taxpayer 
that is not eligible to or does not elect to determine the amount realized using the spot rate on the settlement 
date, such U.S. Holder will recognize foreign currency gain or loss to the extent of any difference between 
the U.S. dollar amount realized on the date of disposition (as determined above) and the U.S. dollar value 
of the currency received at the spot rate on the settlement date. A U.S. Holder’s initial tax basis in our ADSs 
will equal the cost of such ADSs. If a U.S. Holder used foreign currency to purchase our ADSs, the cost of 
our ADSs will be the U.S. dollar value of the foreign currency purchase price on the date of purchase. If our 
ADSs are treated as traded on an established securities market and the relevant U.S. Holder is either a cash 
basis taxpayer or an accrual basis taxpayer who has made the special election described above, such holder 
will determine the U.S. dollar value of the cost of such ADSs by translating the amount paid at the spot rate 
of exchange on the settlement date of the purchase. 

Foreign taxes 

Foreign taxes (if any) withheld or paid on dividends on, or upon the sale or other taxable disposition of, our 
ADSs may, subject to limitations and conditions, be treated as foreign income tax eligible for credit against 
such U.S. Holder’s U.S. federal income tax liability under the U.S. foreign tax credit rules or, at such holder’s 
election, eligible for deduction in computing such holder’s U.S. federal taxable income. If a refund of any 
such foreign tax is available to a U.S. Holder under the laws of the country imposing such tax or under an 
applicable income tax treaty, the amount of such tax that is refundable will not be eligible for the credit or 
deduction  against  the  U.S.  Holder’s  U.S.  federal  income  tax  liability.  Subject  to  the  following  sentence, 
dividends paid on our ADSs will constitute foreign source income and will be considered “passive category” 
income or, in the case of certain U.S. Holders, “general category income,” in computing the foreign tax credit 
allowable to U.S. Holders under U.S. federal income tax laws. However, if we are a “United States-owned 
foreign corporation,” solely for foreign tax credit purposes, a portion of the dividends allocable to our U.S. 
source  earnings  and  profits  may  be  re-characterized  as  U.S.  source.  A  “United  States-owned  foreign 
corporation” is any foreign corporation in which U.S. persons own, directly or indirectly, 50% or more (by 
vote or by value) of the stock. United States-owned foreign corporations with less than 10% of earnings and 
profits attributable to sources within the United States are excepted from these rules. We are currently a 

131

United States-owned foreign corporation. As a result, so long as 10% or more of our earnings and profits 
are attributable to sources within the United States, a portion of the dividends allocable to our U.S. source 
earnings  and  profits  will  be  treated  as  U.S.  source.  In  addition,  any  gain  from  the  sale  or  other  taxable 
disposition of ADSs by a U.S. Holder will constitute U.S. source income. A U.S. Holder may not be able to 
offset any foreign tax withheld or paid as a credit against U.S. federal income tax imposed on that portion 
of any dividends or gain that is U.S. source unless the U.S. Holder has foreign source income or gain in the 
same category from other sources. The rules governing the treatment of foreign taxes imposed on a U.S. 
Holder and foreign tax credits are complex, and U.S. Holders should consult their tax advisors about the 
impact of these rules in their particular situations. 

Passive Foreign Investment Company 

Notwithstanding the foregoing, certain adverse U.S. federal income tax consequences could apply to a U.S. 
Holder if we are treated as a PFIC for any taxable year during which such U.S. Holder holds ADSs. We 
would be classified as a PFIC for any taxable year 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 Code), 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. For 
this purpose, “passive income” includes, subject to certain exceptions, dividends, interest, royalties, rents, 
annuities, gains from commodities and securities transactions, net gains from the sale or exchange of property 
producing such passive income, net foreign currency gains and amounts derived by reason of the temporary 
investment of funds raised in this offering of ADSs. Based on the bases of our assets, the market price of 
our ADSs and the composition of our income, assets and operations, we do not expect to be treated as a 
PFIC for U.S. federal income tax purposes for the current taxable year or in the foreseeable future. However, 
the application of the PFIC rules to us may be subject to ambiguity. In addition, this is a factual determination 
that must be made annually after the close of each taxable year. Therefore, there can be no assurance that 
we will not be classified as a PFIC for the current taxable year or for any future taxable year. Furthermore, 
because PFIC status is a factual determination based on actual results for the entire taxable year, our U.S. 
counsel expresses no opinion with respect to our PFIC status and expresses no opinion with respect to our 
expectations contained in this paragraph. 

If we were classified as a PFIC for any taxable year during which a U.S. Holder held ADSs, such holder 
would be subject to special tax rules with respect to any “excess distribution” that it receives in respect of 
our ADSs and any gain it realizes from a sale or other disposition (including a pledge) of our ADSs, unless 
such holder makes a “mark-to-market” election as discussed below. Under these special tax rules: 

• 

• 

• 

the excess distribution or gain will be allocated ratably over the U.S. Holder’s holding period for our 
ADSs; 

the amount allocated to the current taxable year, and any taxable year in such holder’s holding period 
prior to the first taxable year in which we became a PFIC, will be treated as ordinary income; and 

the amount allocated to each other year will be subject to the highest tax rate in effect for that year and 
the interest charge applicable to underpayments of tax will be imposed on the resulting tax attributable 
to each such year. 

In addition, dividend distributions made to such holder will not qualify for the lower rates of taxation applicable 
to long-term capital gains discussed above under “Distributions.” 

A U.S. Holder will be required to make an annual filing with the Internal Revenue Service if such holder holds 
our ADSs in any year in which we are classified as a PFIC. 

If we are a PFIC for any year during which a U.S. Holder holds our ADSs, we will continue to be treated as 
a PFIC with respect to such holder for all succeeding years during which the holder holds our ADSs. If we 
cease to be a PFIC, such a U.S. Holder may be able to avoid some of the adverse effects of the PFIC regime 
by making a deemed sale election with respect to our ADSs. If such election is made, the U.S. Holder will 
be deemed to have sold the ADSs it holds at their fair market value on the last day of the last taxable year 
in which we qualified as a PFIC, and any gain from such deemed sale would be subject to the consequences 

132

described above. After the deemed sale election, the U.S. Holder’s ADSs with respect to which the deemed 
sale election was made will not be treated as ADSs in a PFIC unless we subsequently become a PFIC. 

If a U.S. Holder is eligible to and does make a mark-to-market election, such holder will include as ordinary 
income the excess, if any, of the fair market value of our ADSs at the end of each taxable year over their 
adjusted basis, and will be permitted an ordinary loss in respect of the excess, if any, of the adjusted basis 
of our ADSs over their fair market value at the end of the taxable year (but only to the extent of the net amount 
of previously included income as a result of the mark-to-market election). Any gain recognized on the sale 
or other disposition of our ADSs will be treated as ordinary income. The mark-to-market election is available 
only for “marketable stock,” which is stock that is traded in other than de minimis quantities on at least 15 
days during each calendar quarter on a qualified exchange or other market, as defined in the applicable 
U.S.  Treasury  regulations.  U.S.  Holders  should  consult  their  own  tax  advisors  regarding  the  potential 
application of the PFIC rules to their ownership of our ADSs. 

A timely election to treat us as a qualified electing fund under the Code would result in an alternative treatment. 
However, we do not intend to prepare or provide the information that would enable U.S. Holders to make a 
qualified electing fund election. 

The U.S. federal income tax rules relating to PFICs are complex. Prospective U.S. investors are urged to 
consult their own tax advisers with respect to the application of the PFIC rules to their investment in the 
ADSs.

U.S. information reporting and backup withholding 

Dividend payments with respect to our ADSs and proceeds from the sale, exchange or redemption of our 
ADSs may be subject to information reporting to the Internal Revenue Service and possible U.S. backup 
withholding. Backup withholding will not apply, however, to a U.S. Holder who furnishes a correct taxpayer 
identification number on a properly completed Internal Revenue Service Form W-9 or otherwise properly 
establishes an exemption from backup withholding. U.S. Holders who are required to establish their exempt 
status may be required to provide such certification on Internal Revenue Service Form W-9. U.S. Holders 
should  consult  their  tax  advisors  regarding  the  application  of  the  U.S.  information  reporting  and  backup 
withholding rules. 

Backup withholding is not an additional tax. Amounts withheld as backup withholding may be credited against 
a U.S. Holder’s U.S. federal income tax liability, if any, and such holder may obtain a refund of any excess 
amounts withheld under the backup withholding rules by timely filing the appropriate claim for refund and 
furnishing any required information to the Internal Revenue Service. 

Foreign financial asset reporting 

Individuals that own “specified foreign financial assets” with an aggregate value in excess of certain threshold 
amounts are required to file an information report with respect to such assets with their tax returns. “Specified 
foreign financial assets” include any financial accounts maintained by foreign financial institutions, as well 
as any of the following, but only if they are not held in accounts maintained by financial institutions: (1) stocks 
and securities issued by non-U.S. persons, (2) financial instruments and contracts held for investment that 
have non-U.S. issuers or counterparties, and (3) interests in foreign entities. Our ADSs may be subject to 
these rules. Additionally, under certain circumstances, an entity may be treated as an individual for purposes 
of these rules. U.S. Holders are urged to consult their tax advisors regarding the application of this requirement 
to their ownership of our ADSs. 

Transfer reporting requirements 

A U.S. Holder (including a U.S. tax-exempt entity) that acquires equity of a newly created non-U.S. corporation 
may be required to file a Form 926 or a similar form with the IRS if (i) such person owned, directly or by 
attribution,  immediately  after  the  transfer  at  least  10.0%  by  vote  or  value  of  the  corporation  or  (ii)  if  the 
transfer, when aggregated with all transfers made by such person (or any related person) within the preceding 

133

 
12-month period, exceeds $100,000. U.S. Holders should consult their tax advisers regarding the applicability 
of this requirement to their acquisition of ADSs. 

THE DISCUSSION ABOVE DOES NOT COVER ALL TAX MATTERS THAT MAY BE IMPORTANT TO 
YOU. EACH PROSPECTIVE PURCHASER SHOULD CONSULT ITS TAX ADVISOR ABOUT THE TAX 
CONSEQUENCES OF AN INVESTMENT IN OUR ADSS UNDER THE INVESTOR’S CIRCUMSTANCES. 

F. Dividends and paying agents

H. Documents on display

We are subject to the periodic reporting and other informational requirements of the Exchange Act, or the 
Exchange Act. Under the Exchange Act, we are required to file reports and other information with the SEC. 
Specifically, we are required to file annually a Form 20-F no later than four months after the close of each 
fiscal year, which is December 31. Copies of reports and other information, when so filed, may be inspected 
without charge and may be obtained at prescribed rates at the public reference facilities maintained by the 
Securities and Exchange Commission at Judiciary Plaza, 100 F Street, N.E., Washington, D.C. 20549. The 
public  may  obtain  information  regarding  the  Washington,  D.C.  Public  Reference  Room  by  calling  the 
Commission at 1-800-SEC-0330. The SEC also maintains a web site at www.sec.gov that contains reports, 
proxy and information statements, and other information regarding registrants that make electronic filings 
with the SEC using its EDGAR system. As a foreign private issuer, we are exempt from the rules under the 
Exchange Act prescribing the furnishing and content of quarterly reports and proxy statements, and officers, 
directors and major shareholders are exempt from the reporting and short-swing profit recovery provisions 
contained in Section 16 of the Exchange Act.

D. American Depositary Shares

Deutsche Bank Trust Company Americas, as depositary, registers and delivers American Depositary Shares, 
also referred to as ADSs. Each ADS represents one Class A share (or a right to receive one Class A share) 
deposited with Deutsche Bank AG, or any successor, as custodian for the depositary. Each ADS will also 
represent any other securities, cash or other property which may be held by the depositary in respect of the 
depositary facility. The depositary’s corporate trust office at which the ADSs will be administered and the 
depositary’s principal executive office is located at 60 Wall Street, New York, New York 10005, United States 
of America. 

A deposit agreement among us, the depositary and you the ADS holders sets out ADS holder rights as well 
as the rights and obligations of the depositary. A copy of the Agreement is incorporated by reference as an 
exhibit to this annual report. 

136

Fees and Expenses 

Pursuant to the terms of the deposit agreement, the holders of ADSs will be required to pay the following

The depositary collects its fees for delivery and surrender of ADSs directly from investors depositing Class 
A shares or surrendering ADSs for the purpose of withdrawal or from intermediaries acting for them. The 
depositary  collects  fees  for  making  distributions  to  investors  by  deducting  those  fees  from  the  amounts 
distributed or by selling a portion of distributable property to pay the fees. The depositary may collect its 
annual fee for depositary services by deduction from cash distributions or by directly billing investors or by 
charging the book-entry system accounts of participants acting for them. The depositary may collect any of 
its fees by deduction from any cash distribution payable to ADS holders that are obligated to pay those fees. 
The depositary may generally refuse to provide for-fee services until its fees for those services are paid. 

From time to time, the depositary may make payments to us to reimburse or share revenue from the fees 
collected from ADS holders, or waive fees and expenses for services provided, generally relating to costs 
and expenses arising out of establishment and maintenance of the ADS program. In performing its duties 
under the deposit agreement, the depositary may use brokers, dealers or other service providers that are 
affiliates of the depositary and that may earn or share fees or commissions.

E. Use of proceeds

On December 21, 2016, we sold 20,826,606 ADSs and our Founders collectively sold 9,200,029 ADSs, each 
representing one Class A share, with a nominal value of €0.06  per share, in our IPO at a public offering price 
of $11.00 per ADS, for an aggregate price of $229.1 million to us and $101.2 million to our Founders. The 
aggregate  net  offering  proceeds  to  us,  after  deducting  underwriting  discounts  and  commissions  totaling 
$21.3 million, were €207.8  million. We did not receive any proceeds from the sale of ADSs by the Founders. 

The offering commenced on December 5, 2016, and the effective date of the Registration Statement on 
Form  F-1,  as  amended  (File  No. 333-214591)  was  December  15,  2016.  J.P.  Morgan  Securities  LLC, 
Goldman, Sachs & Co. and Morgan Stanley & Co. LLC acted as joint book-running managers of the offering 
and as representatives of the underwriters.

None of the payments described in this Item 14 were direct or indirect payments to our directors, officers, 
general partners or their associates, or any persons owning 10% or more of our ordinary shares, or our 
affiliates. As of the date hereof, the majority of the net proceeds from our IPO remained unused. We intend 
to  use  the  remaining  net  proceeds  for  general  corporate  purposes,  including  to  fund  investments  in 
technology, for working capital to fund our growth strategies described elsewhere in this Annual Report and 
to pursue strategic acquisitions, although we have no agreements, commitments or understandings with 
respect to any such transaction.

Item 15: Control and procedures

A. Disclosure controls and procedures

Our chief executive officer and chief financial officer, after evaluating the effectiveness of our disclosure 
controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act) as of December 31, 2017, 
have concluded that, based on such evaluation, the design and operation of our disclosure controls and 
procedures were effective as of December 31, 2017. 

B. Management’s annual report on internal control over financial reporting

Our management is responsible for establishing and maintaining adequate internal control over financial 
reporting, as defined in Rule 13a-15(f) of the Exchange Act. 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. 

Management conducted an evaluation of the effectiveness of our internal control over financial reporting 
based on the criteria for effective control over financial reporting described in Internal Control - Integrated 
Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. 

Based on this evaluation, management has concluded that, as of December 31, 2017, the Company’s internal 
control  over  financial  reporting  was  effective.  Management  has  reviewed  its  assessment  with  the Audit 
Committee. 

Ernst & Young GmbH Wirtschaftsprüfungsgesellschaft, an independent registered public accounting firm, 
has audited the effectiveness of our internal control over financial reporting as of December 31, 2017, as 
stated in their report which is included below.

Limitations on Controls

Management does not expect that our disclosure controls and procedures or our internal control over financial 
reporting will prevent or detect all cases of error and fraud. Any control system, no matter how well designed 
and operated, is based upon certain assumptions and can provide only reasonable, not absolute, assurance 
that  its  objectives  will  be  met.  Further,  no  evaluation  of  controls  can  provide  absolute  assurance  that 
misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, 
within the Company have been detected.

C. Attestation report of the registered public accounting firm

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and the Board of Directors of trivago N.V.

Opinion on Internal Control over Financial Reporting 
We have audited trivago N.V.’s internal control over financial reporting as of December 31, 2017, based on 
criteria  established  in  Internal  Control-Integrated  Framework  issued  by  the  Committee  of  Sponsoring 
Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, trivago 
N.V. (the Company) maintained, in all material respects, effective internal control over financial reporting as 
of December 31, 2017, based on the COSO criteria. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board 
(United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2017 and 

139

 
2016, the related consolidated statements of operations, comprehensive income, changes in equity and 
cash flows for each of the three years in the period ended December 31, 2017, and the related notes and 
our report dated March 6, 2018 expressed an unqualified opinion thereon. 

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

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we 
plan and perform the audit to obtain reasonable assurance about whether effective internal control over 
financial reporting was maintained in all material respects. 

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk 
that a material weakness exists, testing and evaluating the design and operating effectiveness of internal 
control based on the assessed risk, and performing such other procedures as we considered necessary in 
the circumstances. We believe that our audit provides a reasonable basis for our opinion. 

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

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

D. Changes in internal control over financial reporting

A material weakness is defined as a deficiency, or a combination of deficiencies, in internal control over 
financial reporting, such that there is a reasonable possibility that a material misstatement of our annual 
financial statements will not be prevented or detected on a timely basis by our internal controls. In connection 

140

with the preparation of our 2015 financial statements, we identified a material weakness primarily related to 
the lack of sufficient accounting and supervisory personnel with the appropriate level of technical accounting 
experience and training necessary or processes and procedures, particularly in the areas of share-based 
compensation,  build-to-suit  lease  accounting  and  internal  use  software  and  capitalization  of  website 
development costs and other complex, judgmental areas and consequently needed to rely on the assistance 
of outside advisors with expertise in these matters to assist us in our preparation of U.S. GAAP financial 
statements  and  our  compliance  with  SEC  reporting  obligations.  The  material  weakness  remained 
unremediated as of December 31, 2016.

In our efforts to remediate the material weakness described above, we have implemented additional internal 
controls over financial reporting, such as those with respect to the preparation and review of U.S. GAAP 
adjustments, disclosures and significant transactions. We have also hired personnel with the appropriate 
level of technical accounting expertise under U.S. GAAP, strengthened our internal capabilities and expertise 
in  the  preparation  of  our  financial  statements  in  accordance  with  U.S.  GAAP,  created  and  implemented 
accounting policies and enhanced the training of our accounting and financial reporting personnel. Due to 
these additional internal controls and other measures that we have implemented, management determined 
that the previously existing material weakness described above had been remediated as of December 31, 
2017. 

See  “Item  3  D.  Risk  factors—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.”

Item 16A: Audit committee financial expert

Mr. Peter  Kern,  an  independent  director  and  a  member  of  the Audit  Committee,  qualifies  as  an  “audit 
committee financial expert,” as defined in Item 16 A. of Form 20-F and as determined by our supervisory 
board.   

Item 16B: Code of ethics

We have adopted a code of business conduct and ethics that applies to all of our employees, members of 
our senior management and members of our management board and supervisory board, including those 
members of our senior management responsible for financial reporting. Our code of ethics is posted on our 
company website at: http://ir.trivago.com/phoenix.zhtml?c=254450&p=irol-govHighlights. We will disclose 
any substantive amendments to the code of business conduct and ethics, or any waiver of its provisions, 
on our website. The reference to our website does not constitute incorporation by reference of the information 
contained at or available through our website.

Item 16C: Principal accountant fees and services
The  following  table  sets  forth,  for  each  of  the  years  indicated,  the  fees  billed  by  Ernst  & Young  GmbH 
Wirtschaftsprüfungsgesellschaft, our independent registered public accounting firm and the percentage of 
each of the fees out of the total amount billed. Audit fees also include fees for services rendered for the audit 
of our financial statements but charged to our controlling shareholder.

Audit Fees are defined as the standard audit work that needs to be performed each year in order to issue 
opinions  on  our  consolidated  financial  statements  and  to  issue  reports  on  our  local  statutory  financial 
statements. Also included are services that can only be provided by our auditor, such as reviews of quarterly 
financial results, consents and comfort letters and any other audit services required for SEC or other regulatory 
filings. 

Audit Related Fees include those other assurance services provided by the independent auditor but not 
restricted to those that can only be provided by the auditor signing the audit report. 

Tax Fees relate to the aggregate fees for services rendered on tax compliance. 

All Other Fees are any additional amounts billed for products and services provided by the independent 
auditor. 

Pre-Approval Policies and Procedures 

Our Audit Committee has adopted a policy that requires pre-approval of all services performed for us by our 
independent registered public accounting firm, effective for the period following the completion of our IPO. 
The policy was adopted on December 9, 2016. The Audit Committee pre-approval function can be delegated 
to the Audit Committee Chairman or another Audit Committee member outside of meetings.

Item 16D: Exemptions from the listing requirements 
and standards for audit committees
Mr. Alan Pickerill has observer status on our Audit Committee, and he is the Chief Financial Officer of Expedia, 
Inc., our majority shareholder. He relies on the exemption provided in Rule 10A-3(b)(1)(iv)(D) of the Exchange 
Act.  We  do  not  believe  that  his  status  as  an  affiliate  materially  adversely  affects  the  ability  of  our Audit 
Committee to act independently or to satisfy the other requirements of the Nasdaq listing standards relating 
to audit committees contained in Rule 10A-3 under the Exchange Act.

Item 16G: Corporate governance
The Sarbanes-Oxley Act of 2002, as well as related rules subsequently implemented by the SEC, requires 
foreign private issuers, including our company, to comply with various corporate governance practices. In 
addition, Nasdaq rules provide that foreign private issuers may follow home country practice in lieu of the 
Nasdaq corporate governance standards, subject to certain exceptions and except to the extent that such 
exemptions  would be contrary  to U.S. federal securities  laws. In  addition  to the  home  country practices 
described under Item 6C. of this annual report, the home country practices followed by our company in lieu 
of Nasdaq rules are described below: 

•  We do not intend to follow the requirement of Nasdaq Listing Rule 5620(c), which requires an issuer to 
provide in its bylaws for a generally applicable quorum, and that such quorum may not be less than one-
third of the outstanding voting stock. Although we must provide shareholders with an agenda and other 
relevant  documents  for  the  general  meeting  of  shareholders,  Dutch  law  does  not  have  a  regulatory 
regime for the solicitation of proxies and the solicitation of proxies is not a generally accepted business 
practice in the Netherlands, thus our practice will vary from the requirement of Nasdaq Listing Rule 
5620(b).

•  We do not intend to follow the requirements of Nasdaq Listing Rule 5605(d), which requires an issuer 
to have a compensation committee that, inter alia, consists entirely of independent directors, and Nasdaq 
Listing  Rule  5605(e),  which  requires  an  issuer  to  have  independent  director  oversight  of  director 
nominations.

•  We do not intend to follow the requirements of Nasdaq Listing Rule 5635, which generally requires an 
issuer to obtain shareholder approval for the issuance of securities in connection with certain events, 
such as the acquisition of stock or assets of another company, the establishment of or amendments to 
equity-based  compensation  plans  for  employees,  a  change  of  control  of  us  and  certain  private 
placements. 

Because we are a foreign private issuer, our management board members, supervisory board members and 
senior  management  are  not  subject  to  short-swing  profit  and  insider  trading  reporting  obligations  under 
Section 16 of the Exchange Act. They will, however, be subject to the obligations to report changes in share 
ownership under Section 13 of the Exchange Act and related SEC rules. 

The Dutch Corporate Governance Code, or DCGC, contains both principles and best practice provisions for 
management boards, supervisory boards, shareholders and general meetings, financial reporting, auditors, 
disclosure, compliance and enforcement standards. As a Dutch company, we are subject to the DCGC and 
are required to disclose in our annual report, filed in the Netherlands, whether we comply with the provisions 
of the DCGC. If we do not comply with the provisions of the DCGC (for example, because of a conflicting 
Nasdaq requirement or otherwise), we must list the reasons for any deviation from the DCGC in our Dutch 
annual board report.

We acknowledge the importance of good corporate governance. However, at this stage, we do not comply 
with all the provisions of the DCGC, to a large extent because such provisions conflict with or are inconsistent 
with the corporate governance rules of Nasdaq and U.S. securities laws that apply to us, or because such 
provisions do not reflect best practices of international companies listed on Nasdaq.

The best practice provisions we do not apply include the following. We may deviate from additional best 
practice provisions in the future. Such deviations will be disclosed in our Dutch annual board report.

In order to safeguard independence of the supervisory board, the DCGC recommends that:

• 

• 

for each ten percent shareholder or group of affiliated shareholders, there is at most one supervisory 
board member who can be considered to be a shareholder representative;

there  is  at  most  one  non-independent  supervisory  board  member  who  cannot  be  considered  as 
independent due to circumstances other than being a shareholder representative; and 

144

• 

the total number of non-independent supervisory board members should account for less than half of 
the total number of supervisory board members. 

A majority of our supervisory board members is independent. It is our view that given the nature of our 
business and the practice in our industry and considering our shareholder structure, it is justified that only 
4 supervisory board members will be independent. We may need to deviate from the DCGC’s independence 
definition for supervisory board members either because such provisions conflict with or are inconsistent 
with the corporate governance rules of Nasdaq and U.S. securities laws that apply to us, or because such 
provisions do not reflect best practices of global companies listed on Nasdaq. We may need to further deviate 
from the DCGC’s independence definition for supervisory board members when looking for the most suitable 
candidates.  For  example,  a  future  supervisory  board  candidate  may  have  particular  knowledge  of,  or 
experience in our industry, but may not meet the definition of independence in the DCGC. As such background 
is very important to the efficacy of our supervisory board, our supervisory board may decide to nominate 
candidates for appointment who do not fully comply with the criteria as listed under best practice provision 
2.1.8 of the DCGC.

The  DCGC  recommends  that  our  supervisory  board  establish  a  selection  and  appointment  committee. 
Because we are a “controlled company” within the meaning of the corporate governance standards of the 
NASDAQ  Global  Select  Market,  we  do  not  believe  that  a  selection  and  appointment  committee  will  be 
beneficial for our governance structure. We have not established and do not intend to establish a selection 
and appointment committee.

The DCGC further recommends that the compensation committee is not chaired by the chairman of the 
supervisory  board.  The  chairman  of  our  supervisory  board  is  also  the  chairman  of  our  compensation 
committee. Given the chairman's expertise and vision, we consider him to be the best person for the job.

Consistent with corporate practice for non-executive members of a board in the United States, the terms of 
office of our supervisory directors run and end simultaneously. Our supervisory board continuously monitors 
succession  of  its  members  as  well  as  the  managing  directors.  In  light  of  this,  we  have  not  drawn  up  a 
retirement  schedule.  Under  our  articles  of  association,  members  of  the  management  board  and  the 
supervisory board shall be appointed on the  basis of  a binding  nomination prepared  by the  supervisory 
board. This means that the nominee shall be appointed to the management board or supervisory board, as 
the case may be, unless the general meeting of shareholders strips the binding nature of the nomination (in 
which case a new nomination shall be prepared for a subsequent general meeting of shareholders). Our 
articles of association will provide that the general meeting of shareholders can only pass such resolution 
by  a  two-thirds  majority  representing  at  least  half  of  the  issued  share  capital.  However,  the  DCGC 
recommends that the general meeting can pass such resolution by simple majority, representing no more 
than one-third of the issued share capital.

Under our articles of association, members of the management board and the supervisory board can only 
be dismissed by the general meeting of shareholders by simple majority, provided that the supervisory board 
proposes the dismissal. In other cases, the general meeting can only pass such resolution by a two-thirds 
majority representing at least half of the issued share capital. Similar to what has been described above, 
the DCGC recommends that the general meeting of shareholders can pass a resolution to dismiss a member 
of the management board or supervisory board by simple majority, representing no more than one-third of 
the issued share capital.

The DCGC recommends against providing equity awards as part of the compensation of a supervisory board 
member. However, the company may wish to deviate from this recommendation and grant equity awards to 
its supervisory board members.

The DCGC further recommends that the management board appoints the senior internal auditor and the 
company secretary, subject to approval by the supervisory board. We have simplified this process as our 
CFO appoints the senior internal auditor and the company secretary, and allow the audit committee to express 
its views regarding the senior internal auditor. 

The  DCGC  recommends  having  a  diversity  policy  for  the  composition  of  the  management  board  and 
supervisory board. We acknowledge the importance of diversity in the broadest sense and consider aspects 

145

of diversity relevant to our company. Although the supervisory board has not set specific targets with respect 
to diversity, the supervisory board believes that it is important for its members to represent diverse viewpoints 
and  further  that  the  personal  backgrounds  and  qualifications  of  the  managing  and  supervisory  board 
members, considered as a group, should provide a significant composite mix of experience, knowledge and 
abilities.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and the Board of Directors of trivago N.V. 

Opinion on the Financial Statements 
We  have  audited  the  accompanying  consolidated  balance  sheets  of  trivago  N.V.  (the  Company)  as  of 
December  31,  2017  and  2016,  and  the  related  consolidated  statements  of  operations,  comprehensive 
income, changes in equity and cash flows for each of the three years in the period ended December 31, 
2017, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial 
statements  present  fairly,  in  all  material  respects,  the  consolidated  financial  position  of  the  Company  at 
December 31, 2017 and 2016, and the consolidated results of its operations and its cash flows for each of 
the three years in the period ended December 31, 2017, in conformity with U.S. generally accepted accounting 
principles. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board 
(United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2017, 
based  on  criteria  established  in  Internal  Control-Integrated  Framework  issued  by  the  Committee  of 
Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated March 6, 
2018 expressed an unqualified opinion thereon.

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

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

Notes to the consolidated financial statements

1.  Organization and basis of presentation

Description of business

trivago N.V., (“trivago” the “Company,” “us,” “we” and “our”) and its subsidiaries offer online meta-search for 
hotels by facilitating consumers’ search for hotel accommodation, through online travel agents (“OTAs”), 
hotel  chains  and  independent  hotels.  Our  search-driven  marketplace,  delivered  on  websites  and  apps, 
provides users with a tailored search experience via our proprietary matching algorithms. We employ a ‘cost-
per-click’ (or “CPC”) pricing structure, allowing advertisers to control their own return on investment and the 
volume of lead traffic we generate for them. During 2013, Expedia, Inc. (the "Parent" or "Expedia") completed 
the purchase of a controlling interest in the Company. 

Initial public offering

In December 2016, we sold 20,826,606 ADSs, each representing one Class A share, with a nominal value 
of  €0.06   per  share,  in  our  initial  public  offering  (“IPO”)  at  a  public  offering  price  of  $11.00  per ADS,  for 
aggregate net offering proceeds to us, after deducting underwriting discounts and commissions, of €207.8 
million.

Corporate reorganization

In connection with the IPO, the Company underwent a corporate reorganization, and as of December 31, 
2016, trivago N.V. was the parent holding company with a 68.3% controlling interest in trivago GmbH. 

Prior to the completion of the IPO, Expedia owned 63.5% and Messrs. Schrömgens, Vinnemeier and Siewert, 
(whom we collectively refer to as the “Founders”) owned 36.5%, in aggregate, of the voting power in trivago 
GmbH. On November 7, 2016, travel B.V., a Dutch private company with limited liability under Dutch law 
was  formed  in  order  to  affect  the  corporate  reorganization.  Prior  to  the  completion  of  the  IPO,  Expedia 
contributed all of its shares in trivago GmbH to travel B.V. in a capital increase in exchange for newly issued 
Class B shares of travel B.V. The Founders contributed 940 shares of trivago GmbH, representing 6.7% of 
their aggregate shareholding in trivago GmbH, to travel B.V. in a capital increase in exchange for newly 
issued Class A shares of travel B.V. As a result of these contributions, 96.3% of the share capital and 99.6% 
of the voting power in travel B.V. was held by Expedia and 3.7% of the share capital and 0.4% of the voting 
power in travel B.V. was held by the Founders, whereas 66.0% of the voting power in trivago GmbH was 
held by travel B.V. and 34.0% of the voting power in trivago GmbH was held by the Founders. Effective with 
the IPO, travel B.V., changed its legal form and became trivago N.V and all Class A and B shares of travel 
B.V. were converted to Class A and B shares of trivago N.V.

ADSs representing the 9,200,029 Class A shares of the Founders in trivago N.V. and an additional 20,826,606
ADSs representing newly issued Class A shares in trivago N.V. were sold in the IPO. 

After the IPO and as of December 31, 2016, 68.3% of the voting power in trivago GmbH was held by trivago 
N.V. and 31.7% was held by the Founders which is reflected as noncontrolling interest in the consolidated 
financial statements through September 7, 2017. On September 7, 2017 (the "merger date") the merger of 
trivago GmbH into and with trivago N.V. became effective. Pursuant to the merger, our founders exchanged 
all of their units of trivago GmbH remaining after our pre-IPO corporate reorganization for Class B shares 
of trivago N.V.  

As of December 31, 2017, Expedia’s ownership interest and voting interest in trivago N.V. is 59.6% and 
64.7%, respectively, and the Founders had an ownership interest and voting interest of 31.6% and 34.3%, 
respectively.

F-11

Basis of presentation

The  corporate  reorganization,  as  described  above,  is  considered  a  transaction  between  entities  under 
common  control.  As  a  result,  the  financial  statements  for  periods  prior  to  the  IPO  and  the  corporate 
reorganization  are  the  financial  statements  of  trivago  GmbH  as  the  predecessor  to  the  Company  for 
accounting and reporting purposes. Upon the merger of trivago GmbH with and into trivago N.V., the merger 
date,  no  further  noncontrolling  interest  exists  between  trivago  GmbH  and  trivago  N.V.  Unless  otherwise 
specified, “the Company” refers to trivago N.V., and trivago GmbH and its respective subsidiaries throughout 
the remainder of these notes.

These consolidated financial statements reflect Expedia’s basis of accounting due to the change in control 
in 2013 when Expedia acquired a controlling ownership in trivago, as we elected the option to apply pushdown 
accounting in the period in which the change in control event occurred.

Expedia incurs certain costs on behalf of trivago. The consolidated financial statements reflect the allocation 
of certain of Expedia’s corporate expenses to trivago (see Note 17 - Related party transactions for further 
information). We recorded all corporate allocation charges from Expedia within our consolidated statement 
of operations and as a contribution from Parent within the consolidated statement of changes in equity. Our 
management believes that the assumptions underlying the consolidated financial statements are reasonable. 
However,  this  financial  information  does  not  necessarily  reflect  the  future  financial  position,  results  of 
operations  and  cash  flows  of  trivago,  nor  does  it  reflect  what  the  historical  financial  position,  results  of 
operations  and  cash flows of trivago  would  have been  had  we been  a stand-alone  company  during  the 
periods presented.

Seasonality

We experience seasonal fluctuations in the demand for our services as a result of seasonal patterns in travel. 
For example, hotel 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 in the first and 
fourth quarter of the year as we typically expect to advertise less in the periods outside of high travel seasons, 
although the expected increase in return on advertising spend was less pronounced in the fourth quarter of 
2017. 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 spending. The continued 
growth 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.

2. 

Significant accounting policies

Consolidation

Our consolidated financial statements include the accounts of trivago and entities we control. All significant 
intercompany balances and transactions have been eliminated in consolidation. When control is lost, these 
entities will be deconsolidated from our future results of operations effectively immediately on the date of 
losing control. Further, for any entities whereby we may have a financial interest in but do not have control, 
we account for these entities as an equity investment. 

We record noncontrolling interest in our consolidated financial statements to recognize the minority ownership 
interest in our consolidated subsidiaries. Noncontrolling interest in the earnings and losses of consolidated 
subsidiaries represent the share of net income or loss allocated to members or partners in our consolidated 
entities,  which  includes  the  noncontrolling  interest  share  of  net  income  or  loss  from  our  redeemable 
noncontrolling interest entities and our noncontrolling interest in trivago GmbH; up and until the merger of 
trivago GmbH with and into trivago N.V. on September 7, 2017.

F-12

As discussed in Note 1, as a result of the corporate reorganization, trivago N.V. consolidates trivago GmbH 
and trivago GmbH is considered to be the predecessor to trivago N.V. for accounting and reporting purposes. 
As a result of the merger of trivago GmbH with and into trivago N.V. during 2017, as of December 31, 2017 
there no longer remains a minority interest related to trivago GmbH classified as noncontrolling interest as 
a component of stockholders’ equity in our consolidated financial statements.

As of December 31, 2017 all subsidiaries of the Company are wholly-owned. In 2016 and throughout 2017 
until the deconsolidation of myhotelshop, noncontrolling interests with shares redeemable at the option of 
the minority holders in myhotelshop and base7 have been included in redeemable noncontrolling interests. 
We classify the redeemable noncontrolling interest as a mezzanine equity below non-current liabilities in our 
consolidated financial statements. See Note 12 - Redeemable noncontrolling interests for further discussion.

Accounting estimates

We use estimates and assumptions in the preparation of our consolidated financial statements in accordance 
with accounting principles generally accepted in the United States (“GAAP”). Our estimates and assumptions 
affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of 
the date of our consolidated financial statements. These estimates and assumptions also affect the reported 
amount of net income or loss during any period. Our actual financial results could differ significantly from 
these estimates. The significant estimates underlying our consolidated financial statements include revenue 
recognition, intangible assets and goodwill, redeemable noncontrolling interest, acquisition purchase price 
allocations, and share-based compensation.

Revenue recognition

We recognize revenue from services rendered when it is earned and realizable based on the following criteria: 
persuasive  evidence  of  an  arrangement  exists,  services  have  been  rendered,  the  price  is  fixed  or 
determinable, and collectability is reasonably assured. 

Revenue is generated each time a visitor to one of our websites or apps clicks on a hotel room offer in our 
search results and is referred to one of our advertisers. Advertisers pay on a per referral basis, with the 
aforementioned visitor click-through being considered a single referral. Given the nature of the industry, it 
is not unusual for referrals to be generated from automated scripts designed to browse and collect data on 
our websites. However, review processes are in place to identify anomalies to ensure revenue recognition 
is appropriate. Pricing is determined through a competitive bidding process whereby advertisers bid on their 
placement priority for a specific room offer within each room listing. Bids can be placed as often as daily, 
and changes in bids are applied on a prospective basis on the following day. Additionally, a portion of our 
revenue  is  generated  through  subscription-based  services  earned  through  trivago  Hotel  Manager  Pro 
applications. This revenue is recognized ratably over the subscription period and deferred revenue is recorded 
on the balance sheet for amounts invoiced in advance of revenue recognition.

Cost of revenue

Cost of revenue consists of expenses that are directly or closely correlated to revenue generation, including 
data  center  costs,  salaries  and  share-based  compensation  for  our  data  center  operations  staff  and  our 
customer service team who are directly involved in revenue generation. For the three years ended December 
31, 2015, 2016 and 2017 cost of revenue excludes €19.9  million, €3.8  million and €0.1  million, respectively, 
of amortization expense of acquired technology. For the years ended December 31, 2015, 2016 and 2017
cost of revenue excludes €0.5  million, €1.4  million and €1.7  million, respectively, of amortization expense 
related to internal use software and website development. 

F-13

Cash and Cash Equivalents

Our cash and cash equivalents include cash and liquid financial instruments, primarily time deposit 
investments, with maturities of three months or less when purchased.

Restricted cash

Restricted cash primarily consists of funds held as guarantees in connection with corporate leases and funds 
held in escrow accounts in the event of default on corporate credit card statements. The carrying value of 
restricted cash approximates its fair value. As of December 31, 2016 and December 31, 2017, restricted 
cash was €0.9  million and €2.7  million, respectively. From the total balance as of December 31, 2017, €2.6 
million is presented as other long-term assets based on the expected dates the restricted cash will be refunded 
or made available to the Company.

Accounts receivable

Accounts receivable are generally due within 30 days and are recorded net of an allowance for doubtful 
accounts. We determine our allowance by considering a number of factors, including the length of time trade 
accounts receivable are past due, previous loss history, a specific customer’s ability to pay its obligations to 
us, and the condition of the general economy and industry as a whole.

Property and equipment, net including software and website capitalization

We record property and equipment at cost, net of accumulated depreciation and amortization. We compute 
depreciation using the straight-line method over the estimated useful lives of the assets, which is generally 
three  to  five  years  for  computer  equipment,  capitalized  software  development  and  furniture  and  other 
equipment.  We  amortize  leasehold  improvement  using  the  straight-line  method,  over  the  shorter  of  the 
estimated useful life of the improvement or the remaining term of the lease, the majority of which will be fully 
amortized through 2018.

Certain direct development costs associated with website and internal-use software are capitalized during 
the application development stage. Capitalized costs include external direct costs of services and payroll 
costs  (including  share-based  compensation).  The  payroll  costs  are  for  employees  devoting  time  to  the 
software development projects principally related to website and mobile app development, including support 
systems, software coding, designing system interfaces and installation and testing of the software. These 
costs are recorded as property and equipment and are generally amortized over a period of three years 
beginning when the asset is ready for use. Costs incurred for enhancements that are expected to result in 
additional  features  or  functionality  are  capitalized  and  amortized  over  the  estimated  useful  life  of  the 
enhancements, which is generally a period of three years. Costs incurred during the preliminary project 
stage, as well as maintenance and training costs, are expensed as incurred. 

Certain  acquired  software  licenses  and  implementation  costs  are  capitalized  during  the  implementation 
stage. Capitalized costs include the license fee, external direct costs of services provided in regards to the 
implementation and customization of the software, and internal payroll costs for employees involved with 
the implementation process. These costs are recorded as property and equipment and are amortized over 
the license term when the asset is ready for use. Costs incurred during the preliminary project stage, as well 
as maintenance and training costs, are expensed as incurred.

Leases

We lease office space in several countries under non-cancelable lease agreements. We generally lease our 
office facilities under operating lease agreements. We recognize rent expense on a straight-line basis over 
the lease period. Any lease incentives are recognized as reductions of rental expense on a straight-line basis 
over the term of the lease. The lease term begins on the date we become legally obligated for the rent 
payments or when we take possession of the office space, whichever is earlier.

We establish assets and liabilities for the estimated construction costs incurred under lease arrangements 
where we are considered the owner for accounting purposes only, or build-to-suit leases, to the extent that 

F-14

we  are  involved  in  the  construction  of  structural  improvements  or  take  construction  risk  prior  to 
commencement of a lease.

In July 2015, we entered into a lease for new corporate headquarters in Düsseldorf, Germany which is under 
construction  and  will  have  26,107  square  meters  of  office  space. As  a  result  of  our  involvement  in  the 
construction project and our responsibility for paying a portion of the costs of normal finish work and structural 
elements of the premises, the Company was deemed to be the owner of the premises for accounting purposes 
during the construction period pursuant to build-to-suit lease accounting guidance under ASC 840. Therefore, 
the Company recorded project construction costs during the construction period incurred by the landlord as 
a construction-in-progress asset and a related construction financing obligation on our consolidated balance 
sheets. The amounts that the Company has paid or incurred for normal tenant improvements and structural 
improvements had also been recorded as part of the construction-in-progress asset.

We have a lease that includes both building and land. We have bifurcated our lease payments pursuant to 
the premises into: a portion that is allocated to the building (a reduction to the financing obligation); and a 
portion that is allocated to the land on which the building was constructed. The portion of the lease obligations 
allocated to the land is treated as an operating lease that commenced in July 2015. For the years ended 
December 31, 2016 and 2017, we have recorded €1.7  million, respectively, of land rent expense in connection 
with this lease.

Business combinations

We  assign  the  value  of  the  consideration  transferred  to  acquire  a  business  to  the  tangible  assets  and 
identifiable intangible assets acquired and liabilities assumed on the basis of their fair values at the date of 
acquisition. Any excess purchase price over the fair value of the net tangible and intangible assets acquired 
is  allocated  to  goodwill.  When  determining  the  fair  values  of  assets  acquired  and  liabilities  assumed, 
management makes significant estimates and assumptions, especially with respect to intangible assets. 
Critical estimates in valuing certain intangible assets include but are not limited to future expected cash flows 
from  customer  relationships  and  discount  rates.  Management’s  estimates  of  fair  value  are  based  upon 
assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a 
result, actual results may differ from estimates.

Recoverability of goodwill and indefinite-lived intangible assets

Goodwill is assigned to our three reporting units, which correspond to our three operating segments, on the 
basis of their relative fair values as of the date of change in reporting units. We assess goodwill and indefinite-
lived assets, neither of which are amortized, for impairment annually in the fourth quarter of the year, or more 
frequently, if events and circumstances indicate that an impairment may have occurred. In the evaluation of 
goodwill for impairment, we typically first perform a qualitative assessment to determine whether it is more 
likely than not that the fair value of each reporting unit is less than its carrying amount, followed by performing 
a quantitative assessment by comparing the fair value of the reporting unit to the carrying value, if necessary. 
Effective  October  1,  2017,  we  prospectively  adopted  accounting  guidance  that  simplified  our  goodwill 
impairment testing by eliminating the requirement to calculate the implied fair value of goodwill (formerly 
"Step 2") in the event an impairment is identified. Instead, an impairment charge is recorded based on the 
excess of the reporting unit's carrying amount over its fair value. 

We generally base the measurement of fair value of our three reporting units on a blended analysis of the 
present value of future discounted cash flows and market valuation approach. The discounted cash flows 
model indicates the fair value of the reporting unit based on the present value of the cash flows that we 
expect the reporting unit to generate in the future. Our significant estimates in the discounted cash flows 
model include our weighted average cost of capital, long-term rate of growth and profitability of our business. 
The market valuation approach indicates the fair value of the business based on a comparison of the reporting 
unit to comparable publicly traded firms in similar lines of business. Our significant estimates in the market 
approach  model  include  identifying  similar  companies  with  comparable  business  factors,  such  as  size, 
growth, profitability, risk and return on investment and assessing comparable revenue and operating income 
multiples in estimating the fair value of the reporting unit.

F-15

We believe the weighted use of discounted cash flows and market approach is the best method for determining 
the fair value of our reporting units because these are the most common valuation methodologies used within 
the travel and Internet industries? and the blended use of both models compensates for the inherent risks 
associated with either model if used on a stand-alone basis.

In addition to measuring the fair value of our reporting units as described above, we consider the combined 
carrying and fair values of our reporting units in relation to the company’s total fair value. 

In our evaluation of our indefinite-lived intangible assets, we typically first perform a qualitative assessment 
to determine whether the fair value of the indefinite-lived intangible assets is more likely than not impaired.  
If so, we perform a quantitative assessment and an impairment charge is recorded for the excess of the 
carrying value of the indefinite-lived intangible assets over the fair value. We base our measurement of the 
fair value of our indefinite-lived intangible assets, which consist of trade name, trademarks, and domain 
names 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. As with goodwill, periodically, we may choose to forgo the initial qualitative assessment and perform 
a quantitative analysis in our annual evaluation of indefinite-lived intangible assets.

Recoverability of intangible assets with definite lives and other long-lived assets

Intangible assets with definite lives and other long-lived assets are carried at cost and are amortized on a 
straight-line basis over their estimated useful lives of generally less than seven years. We review the carrying 
value of long-lived assets or asset groups, including property and equipment whenever events or changes 
in circumstances indicate that the carrying amount of the assets might not be recoverable. Factors that would 
necessitate an impairment assessment include a significant adverse change in the extent or manner in which 
an asset is used, a significant adverse change in legal factors or the business climate that could affect the 
value of the asset, or a significant decline in the observable market value of an asset, among others. If such 
facts indicate a potential impairment, we would assess the recoverability of an asset group by determining 
if the carrying value of the asset group exceeds the sum of the projected undiscounted cash flows expected 
to result from the use and eventual disposition of the assets over the remaining economic life of the primary 
asset in the asset group. If the recoverability test indicates that the carrying value of the asset group is not 
recoverable, we will estimate the fair value of the asset group using appropriate valuation methodologies, 
which would typically include an estimate of discounted cash flows. Any impairment would be measured as 
the difference between the asset group’s carrying amount and its estimated fair value.

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,  tax  sharing 
agreements  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 

F-16

statements. Interest and penalties related to uncertain tax positions are classified in the financial statements 
as a component of income tax expense.

Presentation of taxes in the statements of operations

We present taxes that we collect from advertisers and remit to government authorities on a net basis in our 
consolidated statements of operations.

Foreign currency translation and transaction gains and losses

The consolidated Financial Statements have been prepared in euros, the reporting currency. Certain of our 
operations outside of the Eurozone use the local currency as their functional currency. We translate revenue 
and expense at average exchange rates during the period and assets and liabilities at the exchange rates 
as of the consolidated balance sheet dates and include such foreign currency translation gains and losses 
as a component of other comprehensive income. Due to the nature of our operations and our corporate 
structure, we also have subsidiaries that have significant transactions in foreign currencies other than their 
functional currency. We record transaction gains and losses in our consolidated statements of operations 
related to the recurring remeasurement and settlement of such transactions.

Advertising expense

We incur advertising expense consisting of offline costs, including television and radio advertising, as well 
as online advertising expense to promote our brands. A significant portion of traffic from users is directed to 
our  websites  through  our  participation  in  display  advertising  campaigns  on  search  engines,  advertising 
networks, affiliate websites and social networking sites. We consider traffic acquisition costs to be indirect 
advertising fees. We expense the production costs associated with advertisements in the period in which 
the  advertisement  first  takes  place.  We  expense  the  costs  of  communicating  the  advertisement  (e.g., 
television airtime) as incurred each time the advertisement is shown. These costs are included in selling and 
marketing expense in our consolidated statements of operations. For the years ended December 31, 2015, 
2016 and 2017, our advertising expense was € 432.2 million, € 623.5 million and € 884.7 million, respectively. 
As of December 31, 2016 and 2017, we had € 5.3 million and € 12.6 million, respectively, of prepaid marketing 
expenses included in prepaid expenses and other current assets.

Share-based compensation 

Share-based compensation included in our consolidated financial statements relates to certain outstanding 
trivago employee options replaced with new trivago employee option awards exercisable into trivago Class 
A shares, in connection with the controlling-interest acquisition of trivago by Expedia in 2013. During 2017, 
there were additional options granted in connection with the Omnibus Incentive Plan to employees of trivago. 

The fair value of share options accounted for as equity settled transactions is measured at the grant date 
using  the  Black–Scholes  option  pricing  model.  The  valuation  model  incorporates  various  assumptions 
including expected volatility of equity, expected term and risk-free interest rates. As we do not have a trading 
history relatable to the expected term of our awards, the expected share price volatility for our Class A shares 
was  estimated  by  taking  the  average  historic  price  volatility  for  industry  peers  based  on  daily  price 
observations over a period commensurate to the expected term. Prior to the IPO, we previously based our 
expected term assumptions on the terms and conditions of the employee share option agreements, and 
scheduled exercise windows. Post IPO, we have used the simplified method in determining the term by 
using the midpoint between the vesting date and the end of the contractual term to estimate the term for all 
option grants subsequent of the IPO. The simplified method was used as we do not have sufficient relatable 
historical term data is available. Prior to the IPO, the share price assumption used in the model is based 
upon a valuation of trivago’s shares as of the grant date utilizing a blended analysis of the present value of 
future discounted cash flows and a market valuation approach. Post IPO, the share price assumption used 
in the model is based our publicly traded share price on the date of grant. We amortize the fair value to the 
extent the awards qualify for equity treatment, over the vesting term on a straight-line basis. The majority of 
our share options are service-based awards which vest between one and three years and have contractual 
terms that align with prescribed liquidation windows.

F-17

We  have  performance-based  share  options  which  vest  upon  achievement  of  certain  company-based 
performance conditions and service conditions. On the date of grant, we determine the fair value of the 
performance-based award using the Black-Scholes option pricing model. The awards are then assessed to 
determine the probability of the award vesting. If assessed as probable, we record compensation expense 
for  these  awards  over  the  total  performance  and  service  period  using  the  accelerated  method. At  each 
reporting period, we reassess the probability of achieving the performance targets, which requires judgment, 
and to the extent actual results or updated estimates differ from our current estimates, the cumulative effect 
on current and prior periods of those changes will be recorded in the period estimates are revised, or the 
change in estimate will be applied prospectively depending on whether the change affects the estimate of 
total  compensation  cost  to  be  recognized.  The  ultimate  number  of  shares  issued  and  the  related 
compensation expense recognized will be based on a comparison of the final performance metrics to the 
specified targets.

We classify certain employee option awards as liabilities when we deem it not probable that the employees 
holding the awards will bear the risk and rewards of stock ownership for a reasonable period of time. We 
remeasure these instruments at fair value at the end of each reporting period using a Black-Scholes option 
pricing model which relies upon an estimate of the fair value of trivago’s shares as of the reporting date 
which is determined using a blended approach as discussed above. Upon settlement of these awards, our 
total  share-based  compensation  expense  recorded  from  grant  date  to  settlement  date  will  equal  the 
settlement amount.

We recognize the effect of forfeitures in the period that the award was forfeited.

Fair value recognition, measurement and disclosure

The carrying amounts of cash and restricted cash reported on our consolidated balance sheets approximate 
fair value as we maintain them with various high-quality financial institutions. The accounts receivable are 
short-term in nature and their carrying value generally approximates fair value. 

We disclose the fair value of our financial instruments based on the fair value hierarchy using the following 
three categories:

Level 1 - Valuations based on quoted prices for identical assets and liabilities in active markets.

Level 2 - Valuations based on observable inputs other than quoted prices included in Level 1, such as 
quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar 
assets  and  liabilities  in  markets  that  are  not  active,  or  other  inputs  that  are  observable  or  can  be 
corroborated by observable market data.

Level 3 - Valuations based on unobservable inputs reflecting the Company’s own assumptions, consistent 
with reasonably available assumptions made by other market participants. These valuations require 
significant judgment.

Certain risks and concentration of credit risk

Our  business  is  subject  to  certain  risks  and  concentrations  including  dependence  on  relationships  with 
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 the Company's cash and 
customers with significant accounts receivable balances.

Our  customer  base  includes  primarily  online  travel  agencies  and  hoteliers.  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,  our  controlling  shareholder,  and  its  affiliates 
represent 39%, 36% and 36%, respectively, of our revenue for the years ended December 31, 2015, 2016 
and 2017, and 31% and 47%, respectively, of total accounts receivable as of December 31, 2016 and 2017. 
Booking Holdings and its affiliates represent 27%, 43% and 44%, respectively, of revenues for the years 
ended December 31, 2015, 2016 and 2017 and 48% and 28%, respectively, of total accounts receivable as 
of December 31, 2016 and 2017.

F-18

Contingent liabilities

From time to time, we may be involved in various claims and legal proceedings relating to claims arising out 
of our operations, as discussed further in Note 16 - Commitments and contingencies. Periodically, and at 
year end, we review the status of all significant outstanding matters to assess the potential financial exposure. 
When (i) it is probable that an asset has been impaired or a liability has been incurred and (ii) the amount 
of the loss can be reasonably estimated, we record the estimated loss in our consolidated statements of 
operations. We provide disclosure in the notes to the consolidated financial statements for loss contingencies 
that do not meet both of these conditions if there is a reasonable possibility that a loss may have been 
incurred that would be material to the financial statements. Significant judgment is required to determine the 
probability that a liability has been incurred and whether such liability is reasonably estimable. We base 
accruals made on the best information available at the time, which can be highly subjective. The final outcome 
of  these  matters  could  vary  significantly  from  the  amounts  included  in  the  accompanying  consolidated 
financial statements. See Note 16 - Commitments and contingencies.

Adoption of new accounting pronouncements

In March 2016, the FASB issued new guidance related to accounting for share-based payments. The updated 
guidance  changes  how  companies  account  for  certain  aspects  of  share-based  payments  awards  to 
employees, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, 
as well as classification in the statement of cash flows. The guidance is effective for annual and interim 
reporting periods beginning after December 15, 2016. The adoption of this new guidance on January 1, 2017 
did not have a material impact to our consolidated financial statements. 

In January 2017, the FASB issued ASU 2017-04, which simplifies the test for goodwill impairment where 
step 2 of the formal goodwill test is eliminated. We have adopted this new guidance for goodwill impairment 
assessments performed from October 1, 2017 . The adoption of this new guidance did not have a material 
impact to our consolidated financial statements.

Recent accounting policies not yet adopted

In May 2014, the FASB issued Accounting Standards Update ("ASU") 2014-09 amending revenue recognition 
guidance and requiring more detailed disclosures to enable users of financial statements to understand the 
nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. In 
August 2015, the FASB issued ASU 2015-14 deferring the effective date of the revenue standard so it would 
be effective for annual and interim reporting periods beginning after December 15, 2017. In addition, the 
FASB has also issued several amendments to the standard, which clarify certain aspects of the guidance. 

The guidance permits two methods of adoption: retrospectively to each prior reporting period presented (full 
retrospective), or retrospectively with the cumulative effect of initially applying the guidance recognized at 
the date of initial application (modified retrospective). We will adopt this new guidance in the first quarter of 
2018 and apply the modified retrospective method. We have determined the new guidance will not change 
the timing or amount of revenue to be recognized. We do expect impacts from the new revenue guidance 
on the presentation of our financial statements, as deferred revenue is going to be presented as contract 
liability in the future. We have completed our overall assessment and we have identified and implemented 
changes to our accounting policies and practices, business processes, and controls to support the new 
revenue recognition standard. We are continuing our assessment of potential changes to our disclosures 
under the new guidance.

In January 2016, the FASB issued ASU 2016-01 that provides new guidance related to accounting for equity 
investments, financial liabilities under the fair value option, and the presentation and disclosure requirements 
for financial instruments. The new standard is effective for annual periods, and interim periods within those 
annual periods, beginning after December 15, 2017. We will adopt this new guidance on January 1, 2018. 
A material impact on the financial statements is currently not expected.

In February 2016 and January 2018, the FASB issued ASU 2016-02 and ASU 2018-01 that provide new 
guidance related to accounting and reporting guidelines for leasing arrangements. The new guidance requires 
entities that lease assets to recognize assets and liabilities on the balance sheet related to the rights and 

F-19

obligations created by those leases regardless of whether they are classified as finance or operating leases. 
Consistent with current guidance, the recognition, measurement, and presentation of expenses and cash 
flows arising from a lease primarily will depend on its classification as a finance or operating lease. The 
guidance also requires new disclosures to help financial statement users better understand the amount, 
timing and uncertainty of cash flows arising from leases. This guidance is effective for annual and interim 
reporting periods beginning after December 15, 2018. Early adoption is permitted and should be applied 
using a modified retrospective approach. We are in the process of evaluating the impact of adopting this 
new guidance on our consolidated financial statements.

In August and November 2016, the FASB issued ASU 2016-15 and ASU 2016-18, that include new guidance 
related to the statement of cash flows, which clarifies how companies present and classify certain cash 
receipts  and  cash  payments  as  well  as  amends  current  guidance  to  address  the  classification  and 
presentation of changes in restricted cash in the statement of cash flows. The new guidance is effective for 
annual periods, and interim periods within those annual periods, beginning after December 15, 2017 with 
early adoption permitted. We will adopt this new guidance on January 1, 2018 retrospectively and currently 
anticipate the most significant impact to be inclusion of those amounts deemed to be restricted cash and 
restricted cash equivalents in our cash and cash-equivalent balances in the consolidated statement of cash 
flows.

In October 2016, the FASB issued ASU 2016-16 amending the accounting for income taxes associated with 
intra-entity transfers of assets other than inventory. This accounting update is intended to reduce diversity 
in practice and the complexity of tax accounting, particularly for those transfers involving intellectual property. 
This new guidance requires an entity to recognize the income tax consequences of an intra-entity transfer 
of an asset other than inventory when the transfer occurs. The new standard is effective for annual periods, 
and interim periods within those annual periods, beginning after December 15, 2017. We will adopt this new 
guidance on January 1, 2018. A material impact on the financial statements is currently not expected.

In January 2017, the FASB issued ASU 2017-01, that clarifies the definition of a business for determining 
whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The 
new standard is effective for annual periods, and interim periods within those annual periods, beginning after 
December 15, 2017. We will adopt this new guidance on January 1, 2018. The standard must be applied 
prospectively. Upon adoption, the standard will impact how we assess acquisitions (or disposals) of assets 
or businesses.

In January 2017, the FASB issued ASU 2017-03, for various topics regarding disclosures of impacts that 
recently issued Accounting Standards will have on the Financial Statements when they are adopted in a 
future period. When adopting the guidance of any of these topics we will also evaluate the impact of this 
guidance. 

In May 2017, the FASB issued ASU 2017-09, about which changes to the terms or conditions of a share-
based payment award require an entity to apply modification accounting. The new standard is effective for 
annual periods, and interim periods within those annual periods, beginning after December 15, 2017. This 
guidance will be taken into account in considering modification accounting when terms or conditions of share-
based payment awards are present.

Acquisitions and divestitures

On  July  16,  2015,  we  completed  the  acquisition  of  a  61.3%  equity  interest  in  myhotelshop  GmbH 
(“myhotelshop”), a marketing manager, for total purchase consideration of €0.6  million consisting of cash 
and the settlement of pre-existing debt at the closing of the acquisition. 

On August  5,  2015,  we  completed  the  acquisition  of  a  52.3%  equity  interest  in  base7booking.com  Sarl 
(“base7”), a cloud-based property management service provider, for total purchase consideration of €2.1 
million in cash. 

F-20

We recognized goodwill of € 2.6 million in the year ended December 31, 2015 from the acquisitions, which 
is primarily attributable to assembled workforce and operating synergies. The goodwill has been allocated 
to our three operating segments and was not deductible for tax purposes. 

The fair value of the noncontrolling interest in myhotelshop and base7 was estimated to be € 2.2 million at 
the time of acquisition. In addition, the purchase agreement of myhotelshop and base7 each contain certain 
put/call rights whereby we may acquire, and the minority shareholders may sell to us, the minority shares 
of the company at fair value. As the noncontrolling interest was redeemable at the option of the minority 
holders, we classified the balance as redeemable noncontrolling interest with future changes in the fair value 
above the initial basis recorded as charges or credits to retained earnings (or additional paid-in capital in 
absence of retained earnings). 

The  acquired  companies  were  consolidated  into  our  financial  statements  on  the  acquisition  date.  We 
recognized € 1.4 million in revenue and € 0.5 million in operating losses for the year ended December 31, 
2015 for base7 and myhotelshop. Acquisition-related costs of € 0.8 million were recognized in the statement 
of operations as general and administrative expenses for the years ended December 31, 2015.

On December 22, 2016, we exercised our call option in order to purchase the remaining 47.7% noncontrolling 
interest in base7 for a cash consideration of approximately €0.9  million. As such, we became the sole owner 
of base7. Given we had a controlling interest in base7 prior to the exercise of the call option, the change in 
ownership  was  treated  as  a  step-acquisition  and  accounted  for  as  an  equity  transaction. As  such,  we 
eliminated  the  redeemable  noncontrolling  interest  of  base7  and  changes  in  redeemable  noncontrolling 
interest due to attributed earnings and foreign exchange gains/losses as of December 22, 2016 and any 
difference between carrying value and acquisition value was adjusted to Reserves in shareholders’ equity 
as of that date. See Note 12 - Redeemable noncontrolling interests. 

In August 2017, we acquired all material assets of tripl GmbH through a business combination for a total 
purchase  consideration  of  €0.7  million.  The  acquisition  is  intended  to  enhance  trivago's  product  with 
personalization technology that uses big data and a customer-centric approach.

During December 2017, myhotelshop GmbH issued 8,074 new common shares for a total of €0.1  million to 
a minority shareholder, who was and continues to be an unrelated party to trivago. The capital infusion diluted 
our share in myhotelshop from 61.3% to 49.0%. In addition to the capital infusion, we no longer have any 
put/call rights to purchase the minority interest in myhotelshop. Following the increase in capital, we lost 
controlling  financial  interest  in  myhotelshop.  We  deconsolidated  myhotelshop’s  assets  and  liabilities, 
including  the  historical  redeemable  noncontrolling  interest  of  myhotelshop,  as  of  that  date  from  the 
consolidated financial statements and present our remaining share in myhotelshop as an equity investment, 
initially at fair value, in other long-term assets in the consolidated balance sheet. The fair value of the retained 
investment was determined based on the intrinsic value of myhotelshop underlying the capital contribution 
in  December  2017.  We  recognized  a  gain  from  deconsolidation  of  €2.0  million,  including  a  gain  on  our 
retained noncontrolling investment of €0.4  million and a gain of €1.0  million from the recognition of receivables 
from a loan granted to myhotelshop in 2015.

In June 2015, we signed a contract to build our new corporate headquarters in Düsseldorf, Germany. The 
Company was deemed to be the owner of the premises during the construction period under build-to-suit 
lease  accounting  guidance  under ASC  840.  Therefore,  a  construction-in-progress  asset  and  a  related 
construction financing obligation were recorded on our consolidated balance sheets. The building assets 
are included in construction in process and will begin depreciating when the costs incurred related to the 
build out of the headquarters are complete and the normal tenant improvements are ready for their intended 
use, which is expected to be in 2018.

During 2017, we have incurred costs for special tenant building requests associated with the construction 
of the new corporate headquarter, which are included in construction in process. We will begin depreciating 
when the costs incurred related to the build out of the headquarters are complete and the normal tenant 
improvements are ready for their intended use.

We establish assets and liabilities for the present value of estimated future costs to return certain of our 
leased facilities to their original condition under the authoritative accounting guidance for asset retirement 
obligations. Such assets are depreciated over the lease period and the recorded liabilities are accreted to 
the future value of the estimated restoration costs. As of December 31, 2017, an asset retirement obligation 
asset of €1.0  million is included within leasehold improvements, gross of accumulated depreciation of €0.3 
million, and a liability of €1.0  million for the cost to decommission the physical space of our current operating 
leases for office space once we move into our new corporate headquarter in mid 2018.

Employee benefit plans

For  defined  contribution  plans,  trivago  pays  contributions  to  publicly  or  privately  administered  pension 
insurance plans on a mandatory, contractual or voluntary basis. We have no further payment obligations 
once the contributions have been paid. The contributions are recognized as employee benefit expense when 
they are due. The amount of expense recognized for defined contribution pension plans was not material 
for the years ended December 31, 2015, 2016 and 2017.

10.  Share-based awards and other equity instruments

Option issuance prior to IPO

In  connection  with  the  controlling-interest  acquisition  of  trivago  by  Expedia  in  2013,  certain  outstanding 
trivago employee options as of the acquisition date were replaced with new trivago employee option awards 
exercisable into trivago Class A shares. The replacement awards were exchanged at acquisition date fair 
value and maintained their original service-based vesting schedule and strike price of €1 . The original service-
based  vesting  period  for  these  awards  are  between  one  and  three  years. The  options  also  contained 
conditions which allowed holders to put underlying shares to Expedia (and for which Expedia can call) during 
prescribed liquidity windows in 2016 and 2018, however holders are required to exercise options and hold 
underlying shares for a reasonable period of time prior to liquidation in order to participate in the risks and 
rewards of equity ownership. Of the 887 option awards outstanding as of January 1, 2014, 858 option awards 
were replaced at the time of Expedia’s acquisition of a controlling interest in us and the remaining were 
additional grants in 2013 which contained similar provisions as the replacement awards.

77  and  146  Class A  employee  share  options  were  granted  in  2015  and  2016,  respectively. Additionally, 
62,178 and 74,580 Class B employee share options were granted in 2015 and 2016, respectively, which 
have economic and voting rights that are 1/1000 of a Class A option. Class A and Class B are presented as 
the same class of shares and Class B option awards are presented in terms of Class A equivalents. The 
majority of the employee share options granted in 2015, and 2016 had a strike price of €1 . The remaining 
options granted in 2015 were granted with strike prices which approximated the 2013 acquisition date fair 
value of trivago shares and the remaining 2016 options were granted with a strike price equal to the fair 
value of trivago shares estimated at the time of grant. All option awards granted in 2015 and 2016 contain 
service based vesting provisions between two and three years. The shares subscribed for underlying the 
grants in 2015 and 2016 are eligible to participate in prescribed liquidity events originally scheduled to occur 
in 2016, 2018 and 2020. Options granted with exercise prices in excess of €1  are not expected to participate 
in the risks and rewards of ownership for a reasonable period of time and are therefore accounted for as 
liability awards.

In the third quarter of 2015, 484 Class A equivalent trivago employee option awards were exercised for 
nominal proceeds.  The underlying shares were held by employees in order to participate in the 2016 liquidity 
window. Upon exercise of these options, trivago paid employees’ personal tax liability related to the option 
exercise  collateralized  by  the  underlying  shares  and  to  be  repaid  by  employees  from  2016  liquidation 
proceeds. As the proceeds of €7.1  million were funded by Expedia, trivago recognized a related party payable 
for  this  amount.  trivago’s  extension  of  this  nonrecourse  loan  to  employees  triggered  an  accounting 
modification  and  changed  the  classification  of  the  awards  from  equity  to  liability  accounting  treatment, 
resulting in a one-time modification charge of €7.3  million and subsequent liability accounting treatment 
requiring remeasurement to fair value at each reporting period until settlement in 2016. The shareholder 
loan receivable was netted within the members’ liability balance which reflects the value of the liability awards, 
net of the loan. 

There were certain shares held by trivago employees which were originally awarded in the form of share-
based options pursuant to the trivago employee option plan and subsequently exercised by such employees. 
During the second quarter of 2016, Expedia exercised a call right on these shares and elected to do so at 
a premium to fair value, the aggregate payment of which, €62.5  million, was recorded as a Contribution from 

F-25

Parent in Members’ Equity. The exercise resulted in an incremental share-based compensation charge of 
approximately €43.7  million in the second quarter of 2016 pursuant to liability award treatment. The differential 
between the cash settlement amount and the incremental share-based compensation charge reflects share-
based compensation expense recorded on these awards in previous periods. The €7.1  million related party 
payable and the €7.1  million shareholder loan receivable, netted within the members’ liability balance, was 
extinguished due to cash withheld from proceeds paid to employees by Expedia as part of this call right 
exercised by Expedia. The acquisition of these employee minority interests increased Expedia’s ordinary 
ownership of trivago to 63.5%.

In the third quarter of 2016, 38 Class A equivalent trivago employee option awards were exercised for nominal 
proceeds. All of these awards were liability-classified awards and their subsequent subsequent settlement 
resulted in a reclassification of €4.2  million from Option liability to Reserves in equity. The options exercised 
were later called by Expedia, with the options exercised having strike prices in excess of €1 . Expedia withheld 
all of the proceeds from exercise, which resulted in a €0.7  million payment to trivago and an offsetting impact 
to Reserves in equity.

Amendment to trivago option plan

In conjunction with the IPO of trivago N.V. there was a modification to the trivago option plan on December 
22, 2016. The modification converted the options for shares in trivago GmbH into options for shares in trivago 
N.V. The adjustment to the terms of the options was equitable to the option holder, whereas the fair value 
calculated before and after the adjustment resulted in no incremental fair value. There was no change to 
the vesting or service conditions of the awards due to the amendment to the trivago option plan. The liquidity 
windows in 2018 and beyond are no longer in effect under the amended trivago option plan.

Furthermore, as part of the modification of options for units in trivago GmbH to options for shares in trivago 
N.V.,  all  awards  are  considered  to  be  equity  classified  awards  as  of  the  modification  date.  Prior  to  the 
modification,  certain  awards  with  an  exercise  price  higher  than  €1   were  liability  classified  as  the  option 
holders were not expected to participate in the risks and rewards normally associated with equity share 
ownership for a reasonable period of time. However, with the modification, the employees no longer have 
the option for the Company to settle the options in cash and with the IPO the employees can now have 
access to a liquid market for the shares of trivago N.V., allowing them to participate in the risks and rewards 
or  equity  share  ownership.  The  amendment  to  the  plan  and  modification  resulted  in  a  €4.9  million 
reclassification of the liability for these options to Reserves in equity and the awards are classified as equity 
going forward.

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, directors who are members of the management board 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 shall be 34,711,009 Class A shares. Class A shares issuable 
under the 2016 Plan will be represented by ASDs 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 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 agreed with the supervisory board. Subject to applicable law or the listing standards 
of the applicable exchange, the plan committee may delegate to other appropriate persons the authority to 
grant equity awards under the 2016 Plan to our eligible award recipients. Management board members, 
supervisory board members, officers, employees and consultants of the company or any of our subsidiaries 
or affiliates, and any prospective directors, officers, employees and consultants of the company who have 
accepted offers of employment or consultancy from the company or our subsidiaries or affiliates (excluding 
supervisory board members) are eligible for awards under the 2016 Plan. 

F-26

Awards include options, share appreciation rights, restricted share units and other share-based and cash-
based awards. Awards may be settled in stock or cash. The option exercise price for options granted to 
members of the management board and the supervisory board under the 2016 Plan for management board 
members shall not be less than the fair market value of a Class A share as defined in the 2016 Plan on the 
relevant grant date, unless otherwise approved by shareholders at a general meeting. The option exercise 
price for options under the 2016 Plan for other eligible individuals can be less than the fair market value of 
a Class A share as defined in the 2016 Plan on the relevant grant date. To the extent that listing standards 
of the applicable exchange require the company’s shareholders to approve any repricing of options, options 
may not be repriced without shareholder approval.

Options and share appreciation rights shall vest and become exercisable at such time and pursuant to such 
conditions as determined by the plan committee and as may be specified in an individual grant agreement. 
The plan committee may at any time accelerate the exercisability of any option or share appreciation right. 
Restricted shares may vest based on continued service, attainment of performance goals or both continued 
service and performance goals. The plan committee at any time may waive any of these vesting conditions.

Options and share appreciation rights will have a term of not more than ten years. The 2016 Plan will also 
have a ten- year term, although awards outstanding on the date the 2016 Plan terminates will not be 
affected by the termination of the 2016 Plan.

As of December 31, 2016, there were no awards granted under the 2016 Plan. During 2017, 10,561,001
awards were granted under the 2016 Plan.

trivago amended option plan

Under the trivago amended option plan, we may grant share options and other share-based awards to 
management board and supervisory board members, officers, employees and consultants. We issue new 
shares to satisfy the exercise or settlement of share-based awards.

The following table presents a summary of our share option activity in trivago N.V. equivalent shares for

As discussed above, the options legally exercised in 2015 were subject to an accounting modification that 
changed  their  classification  from  equity  to  liability  awards.  These  awards  remained  subject  to  variable 
accounting treatment through their settlement date in June 2016. Prior to the IPO, 93 Class A and 6 Class

B options (in terms of Class A equivalents options) were subject to liability accounting. As of December, 31, 
2016 and 2017, no option awards are subject to liability accounting.

The total intrinsic value of share options exercised was € 3.0 million and €14.9  million for the year ended 
December 31, 2016 and December 31, 2017, respectively. 

During the three years ended December 31, 2015, 2016 and 2017, we awarded share options as our only 
form of share-based compensation. The fair value of share options granted during the years ended December 
31, 2015, 2016 and 2017 were estimated at the date of grant using the Black-Scholes option-pricing model,

In 2015, 2016 and 2017, we recognized total share-based compensation expense of € 14.1 million, € 53.7 
million and € 16.0 million, respectively. There was no income tax benefit related to share-based compensation 
expense for 2015, 2016 and 2017. Additionally, € 103 thousand, € 318 thousand and € 85 thousand of share-
based  compensation  cost  was  capitalized  in  2015,  2016  and  2017,  respectively,  as  part  of  software 
development costs. 

Cash received from share-based award exercises for the years ended December 31, 2015, 2016 and 2017 
was € 10 thousand, € 686 thousand and € 42 thousand, respectively. 

As of December 31, 2017, there was approximately € 35.1 million in unrecognized share-based compensation 
expense  related  to  unvested  share-based  awards  subject  to  equity  treatment,  which  is  expected  to  be 
recognized in expense over the weighted average period of 2.5 years.

Our effective tax rate was 22.3% in 2015, (14.9)% in 2016 and 26.7% in 2017. This is primarily due to non-
deductible share-based compensation of (pre-tax) € 14.1 million in 2015, € 53.7 million in 2016 and € 16.0 
million in 2017. Furthermore, (pre-tax) corporate costs amounting to € 2.8 million for 2015, € 4.2 million for 
2016 and € 0.1 million in 2017 were pushed down from Expedia. These corporate costs are non-deductible 
for tax purposes. Additional details on the movement in valuation allowance and changes in uncertain tax 
positions are included below.

Other differences relate to one-off items during the year. In 2015, €0.5  million of the total €0.8  million was 
related to the non-tax deductible expense for the release of a contingent asset at the level of trivago GmbH. 
The remainder of the other permanent differences amounts in 2015, 2016 and 2017 relate to individually 
insignificant non-deductible expenses at the level of trivago GmbH.

In  2013,  an  uncertain  tax  position  was  provided  for  related  to  the  deductibility  of  certain  compensation 
payments in 2010 and 2011. In 2015, a tax audit was finalized for the years 2009 through to 2012. This 
resulted in a full release of the uncertain tax position. There are no uncertain tax positions provided for as 
of December 31, 2016 or 2017.

The Company is subject to audit by federal, state, local and foreign income tax authorities. As of December 31, 
2017, for trivago and its subsidiaries, statute of limitations for tax years 2013 through 2017 remain open to 
examination by German tax authorities.

At December 31, 2017 there are no tax returns for trivago or subsidiaries under audit.

At  December 31,  2017,  we  had  net  operating  loss  carryforwards  (“NOLs”)  for  a  tax-effected  amount  of 
approximately €2.5  million. The tax-effected NOL carryforwards decreased by €1.1  million from the amount 
recorded at December 31, 2016 primarily due to utilization of pre-tax losses at the level of the trivago N.V. 

trivago N.V. is a Dutch listed entity, however has its tax residency in Germany. In 2017, trivago N.V. and 
trivago GmbH merged for tax purposes. This merger enables trivago N.V. to offset its NOLs with any future 
taxable profits of trivago GmbH. As a result, the €3.2  million previously unrecognized losses of trivago N.V. 
have been fully recognized in FY 2017. 

Of this €3.2  million, €2.5  million of NOLs have not been utilized at December 31, 2017. If not utilized, the 
tax-effected NOL carryforwards of €2.5  million may be carried forward indefinitely.

The tax-effected valuation allowance decreased by €3.5  million from the amount recorded at December 31, 
2016. Of this €3.5  million decrease in tax-effected valuation allowance, €3.2  million relates to the recognition 
of  previously  unrecognized  losses  at  the  trivago  N.V.  level,  and  €0.3  million  relates  to  the  utilization  of 
previously unrecognized losses at the level of Base7 S.à.r.l., a Swiss subsidiary.

F-30

  
€
€
The amount of the deferred tax asset considered realizable, however, could be adjusted if estimates of future 
taxable  income  during  the  carryforward  period  change,  or  if  objective  negative  evidence  in  the  form  of 
cumulative losses is no longer present and additional weight may be given to subjective evidence such as 
our projections for growth.

The total cumulative amount of undistributed earnings related to investments in certain foreign subsidiaries 
where the foreign subsidiary has or will invest undistributed earnings indefinitely was insignificant (below 
€0.1  million) at December 31, 2017 and therefore we have not provided for deferred income taxes on this 
taxable temporary difference. In the event we distribute such earnings in the form of dividends or otherwise, 
these would be tax exempt for all investments located in Europe. Any capital gains on the sale of participations 
would be 95% exempt under German tax law.

12.  Redeemable noncontrolling interests

Noncontrolling interest existed in myhotelshop until its deconsolidation in December 2017 as it was majority 
owned by us. We carried it at fair value as the noncontrolling interests contained certain rights, whereby we 
may have acquired and the minority shareholders may have sold to us the additional shares of the company. 
A  reconciliation  of  redeemable  noncontrolling  interest  for  the  years  ended  December 31,  2016  and 
December 31, 2017 is as follows:

As of December 31, 2016, the fair value of the redeemable noncontrolling interest has been adjusted by € 1 
million for the net loss attributable to the noncontrolling interest in myhotelshop and the noncontrolling interest 
in base7 through the date of acquisition. A total fair value adjustment has been recorded of € 1 million to 
reflect the fair value of the noncontrolling interests for the year ended December 31, 2016. On December 
22, 2016, we acquired the remaining noncontrolling interest in base7. As the change in ownership interest 
does not result in a loss of control, the acquisition is considered an equity transaction. Consequently, we 
have eliminated the redeemable noncontrolling interest of base7 and changes in redeemable noncontrolling 
interest due to attributed earnings and foreign exchange gains/losses as of December 22, 2016.

As of December 31, 2017, the fair value of the redeemable noncontrolling interest has been adjusted by 
€0.1  million  for  the  net  loss  attributable  to  the  noncontrolling  interest  in  myhotelshop. A  total  fair  value 
adjustment has been recorded of €0.1  million to reflect the fair value of the noncontrolling interests as of the 
deconsolidation  date  of  myhotelshop.  On  December  15,  2017,  after  losing  control  of  myhotelshop,  we 
deconsolidated the entity including the redeemable noncontrolling interests with a fair value of €0.4  million. 

There is no redeemable noncontrolling interest as of December 31, 2017.

13.  Stockholders' equity

Class A and Class B common stock (after the corporate reorganization, see Note 1 - Organization and 
basis of presentation)

F-31

€
€
€
€
As of December 31, 2017, we had ADSs representing 30,916,474 Class A shares outstanding, 319,799,968
Class B shares outstanding. During the third quarter of 2017 the Founders exchanged their units in trivago 
GmbH for 110,791,880 Class B shares in trivago N.V. in connection with the merger of trivago GmbH with 
and into trivago N.V.

Class A and Class B common stock has a par value of €0.06  and €0.60 , respectively. The holder of our Class 
B shares, Expedia and Founders, are entitled to ten votes per share, and holders of our Class A shares are 
entitled to one vote per share. All other terms and preferences of Class A and Class B common stock are 
the same.

Reserves

Reserves primarily represents the effects of pushdown accounting applied due to the change in control in 
2013 in addition to share premium as result of the corporate reorganization and IPO. See Note 1 - Organization 
and basis of presentation. Further effects to the Reserves are due to the merger of trivago GmbH with and 
into trivago N.V. and exercises of employee stock options. 

Accumulated other comprehensive income (loss)

Accumulated  other  comprehensive  income  represents  foreign  currency  translation  adjustments  for  our 
subsidiaries in foreign locations. As of December 31, 2017, we do not expect to reclassify any amounts 
included in accumulated other comprehensive income (loss) into earnings during the next 12 months.  

Contribution from Parent

The beginning contribution from Parent balance represents the pushdown of share-based compensation 
expense from Expedia. The change year over year primarily relates to additional share-based compensation 
expense as well as Expedia corporate expenses allocated to trivago. See Note 1 - Organization and basis 
of presentation, Note 10 - Share-based awards and other equity instruments and Note 17 - Related party 
transactions.

Dividends

In December 2016, trivago GmbH agreed to affect a one-time dividend payment in respect of fiscal year 
2016. The dividend is in the amount of €0.5  million and was paid to shareholders of record prior to the IPO, 
resulting in a €0.2  million cash outflow to trivago N.V. in the year ended December 31, 2017.

14.  Earnings per share

Effective with our IPO, basic and diluted earnings per share of Class A and Class B common stock is computed 
by dividing net income attributable to trivago N.V., after adjusting for noncontrolling interest, by the weighted 
average number of Class A and Class B common stock outstanding during the same period. Diluted earnings 
per share is calculated using our weighted-average outstanding common shares including the dilutive effect 
of stock awards as determined under the treasury stock method.

There were no shares of Class A or Class B common stock outstanding prior to December 16, 2016, therefore 
no earnings per share information has been presented for any period prior to that date.

The following table presents our basic and diluted earnings per share:

16.  Commitments and contingencies

Credit facility, purchase obligations and guarantees

We have commitments and obligations which include purchase commitments, which could potentially require 
our payment in the event of demands by third parties or contingent events. Commitments and obligations

Our purchase obligations represent 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.

Lease commitments

We have contractual obligations in the form of operating leases for office space and related office equipment. 
Certain leases contain periodic rent escalation adjustments and renewal options. Rent expense related to 
such leases is recorded on a straight-line basis over the lease term. Lease obligations expire at various 
dates through 2038. For the years ended December 31, 2015, 2016 and 2017, our rental expense was €3.3 
million, €4.6  million and €4.8  million, respectively.

Currently recognized on our balance sheet as of December 31, 2017 is an asset retirement obligation of 
€1.0  million related to our main headquarters located in Düsseldorf, Germany.

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. 

The following table presents our estimated future minimum rental payments under operating leases with 
noncancelable lease terms that expire after December 31, 2017:

Legal proceedings

From time to time, we may be involved in various claims and legal proceedings relating to claims arising out 
of our operations. We also evaluate other potential contingent matters, including value-added tax, excise 
tax, sales tax, transient occupancy or accommodation tax and similar matters. 

The Australian Competition and Consumer Commission, or ACCC, has requested information and documents 
from us relating to our advertisements in Australia concerning the hotel prices available on our Australian 
site and our strike-through pricing practice, which is the display adjacent to the price quote in the top position 
in our search results of a higher price that is crossed out. The matter is in its early stages, and we are unable 
to estimate its potential effect on our financial position and results of operations.

trivago N.V. and certain of its management board members are the subject of two purported class actions, 
filed in the United States District Court for the Southern District of New York following the announcement by 
the U.K. Competition and Markets Authority of its industry-wide investigation into online hotel booking sites, 
asserting claims under the Exchange Act and the Securities Act on behalf of persons who purchased or 
otherwise acquired trivago’s American Depositary  Receipts pursuant  and/or traceable to the registration 
statement and prospectus issued in connection with our IPO on or about December 16, 2016 and/or on the 
open  market  between  December  16,  2016  and  October  27,  2017.  One  of  the  complaints  also  named 
underwriters of our IPO as defendants. On January 22, 2018, the court appointed the lead plaintiff and lead 
counsel in the actions, and they now have the opportunity to file an amended complaint. The matter is in its 

F-34

€
early  stages,  and  we  are  unable  to  estimate  its  potential  effect  on  our  financial  position  and  results  of 
operations.

17.  Related party transactions

Relationship with Expedia, Inc.

We have commercial relationships with Expedia and many of its affiliated brands, including Brand Expedia, 
Hotels.com, Orbitz, Travelocity, Wotif, HomeAway and ebookers. These are arrangements terminable at will 
or upon three to seven days’ prior notice by either party and on customary commercial terms that enable 
Expedia’s brands to advertise on our platform, and we receive payment for users we refer to them. We are 
also party to a letter agreement pursuant to which Expedia refers traffic to us when a particular hotel or 
region is unavailable on the applicable Expedia website. Related-party revenue from Expedia of €194.2 
million,  €268.2  million  and  €367.6  million  for  the  years  ended  December 31,  2015,  2016  and  2017, 
respectively, primarily consists of click through fees and other advertising services provided to Expedia and 
its subsidiaries. These amounts are recorded at contract value, which we believe is a reasonable reflection 
of the value of the services provided. Related-party revenue represented 39%, 36% and 36% of our total 
revenue for the years ended December 31, 2015, 2016 and 2017, respectively.

Our operating expenses include a related-party shared services fee, of €2.8  million, €4.2  million and €0.5 
million for the years ended December 31, 2015, 2016 and 2017, respectively. This shared service fee is 
comprised of allocations from Expedia for legal, tax, treasury, audit and corporate development costs and 
includes an allocation of employee compensation within these functions. These expenses were allocated 
based on a number of factors including headcount, estimated time spent and operating expenses which 
trivago considers reasonable estimates. These amounts may have been different had trivago operated as 
an unaffiliated entity. During 2017 a significant portion are now incurred directly by trivago. 

The related party trade receivable balances with Expedia and its subsidiaries reflected in our consolidated 
balance sheets as of December 31, 2016 and 2017 were €16.5  million and €38.6  million. The increase in 
related party receivables was driven by a standardization of related party payment terms, which delayed our 
receipt of related party revenue until after month-end close.

Guarantee

On September 5, 2014, we entered into an uncommitted credit facility with Bank of America Merrill Lynch 
International Ltd., one of the underwriters of our initial public offering, with a maximum principal amount of 
€10.0  million. Advances under this facility bear interest at a rate of LIBOR, floored at zero, plus 1.0% per 
annum. This  facility  may  be  terminated  at  any  time  by  the  lender.  Our  obligations  under  this  facility  are 
guaranteed by Expedia.

On  December  19,  2014,  we  entered  into  an  amendment  to  this  facility  pursuant  to  which  the  maximum 
principal amount was increased to €50.0  million. We utilized €20.0  million of our €50.0  million credit facility 
to fund capital requirements in 2015. During the year ended December 31, 2016, we utilized €20.0  million
under our credit facility and subsequently repaid all obligations outstanding. We did not utilize the credit 
facility during the year ended December 31, 2017. 

On  July  23,  2015,  we  entered  into  an  agreement  to  design  and  build  our  new  headquarters  building  in 
Düsseldorf, Germany. As part of that agreement, Expedia had guaranteed certain payments due by trivago 
under the contract . The guarantee by Expedia ended upon receipt of a bank guarantee by trivago, which 
we obtained in July 2017. As of December 31, 2017 there no longer is a guarantee by Expedia for certain 
payments made by us related to our new headquarters. 

Services agreement

On May 1, 2013, we entered into an Assets Purchase Agreement, pursuant to which Expedia purchased 
certain computer hardware and software from us, and a Data Hosting Services Agreement, pursuant to which 

F-35

Expedia provides us with certain data hosting services relating to all of the servers we use that are located 
within the United States. Either party may terminate the Data Hosting Services Agreement upon 30 days’ 
prior written notice. For each of the years ended December 31, 2015, 2016 and 2017, we paid Expedia €21 
thousand, €21 

thousand, respectively, for these data hosting services

thousand and €68 

Services and support agreement 

On September 1, 2016, we entered into a Services and Support Agreement, pursuant to which Expedia 
agreed to provide us with certain services in connection with localizing content on our websites, such as 
translation services. Either party may terminate the Services and Support Agreement upon 90 days’ prior 
notice. We have not incurred material expenses under this agreement. 

18.  Segment information

Beginning  in  the  second  quarter  of  2016,  management  identified  three  reportable  segments,  which 
correspond  to  our  three  operating  segments:  the Americas,  Developed  Europe  and  Rest  of  World. The 
change from one to three reportable segments was the result of a shift in the Company’s focus on managing 
the business to reflect unique market opportunities and competitive dynamics inherent in our business within 
each of our operating segments. 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 represents all 
regions outside of the Americas and Developed Europe. The top countries by revenue in the Rest of World 
segment include Australia, Japan, India, New Zealand and Hong Kong.  

We determined our operating segments based on how our chief operating decision makers manage our 
business, make operating decisions 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. ROAS includes the allocation of revenue by segment which is based on the location of 
the  website,  or  domain  name,  regardless  of  where  the  consumer  resides.  This  is  consistent  with  how 
management monitors and runs the business. 

Corporate and Eliminations also includes all corporate functions and expenses except for direct advertising. 
In addition, we record amortization of intangible assets and any related impairment, as well as share-based 
compensation expense, restructuring and related reorganization charges, legal reserves, occupancy tax and 
other taxes, and other items excluded from segment operating performance in Corporate and Eliminations. 
Such amounts are detailed in our segment reconciliation below.

The following tables present our segment information for the years ended December 31, 2015, 2016 and 
2017. As a significant portion of our property and equipment is not allocated to our operating segments and 
depreciation is not included in our segment measure, we do not report the assets by segment as it would 
not be meaningful. We do not regularly provide such information to our chief operating decision makers.
