Exhibit 99.1
Operating and Financial Review

The following discussion should be considered together with our unaudited financial information included with this release and the periodic reports we file with the Securities and Exchange Commission, including the section contained in our Annual Report on Form 20-F for the fiscal year ended December 31, 2018, “Item 5. Operating and Financial Review and Prospects.” Certain information and disclosures normally included in consolidated financial statements prepared in accordance with U.S. Generally Accepted Accounting Principles (“U.S. GAAP”) have been omitted from this release.

As used herein, references to “we,” “us,” the “company,” or “trivago,” or similar terms shall mean trivago N.V. and, as the context requires, its subsidiaries.

Overview

trivago is a global hotel and accommodation search platform. We are focused on reshaping the way travelers search for and compare different types of accommodations, such as hotels, vacation rentals and apartments, while enabling our advertisers to grow their businesses by providing them with access to a broad audience of travelers via our websites and apps. Our platform allows travelers to make informed decisions by personalizing their search for accommodations and providing them with access to a deep supply of relevant information and prices. As of September 30, 2019, we offered access to more than 3.5 million hotels and other types of accommodation in over 190 countries, including over 2.3 million units of alternative accommodation, such as vacation rentals and apartments.

Our search platform forms the core of our user experience and can be accessed globally via 55 localized websites and apps available in 33 languages. 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. Additionally, we enhance our users’ experience by giving them the option to display their search results in listing 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. In the third quarter of 2019, our revenue share from mobile websites and apps continued to exceed 60%.

Highlights

In the third quarter of 2019, total revenue decreased to €250.3 million compared to €253.7 million in the same period in 2018, representing a decline of 1% period-over-period.
Referral Revenue increased in Americas in the third quarter of 2019, while Referral Revenue declined in Developed Europe and Rest of World ("RoW") compared to the same period in 2018.
The number of Qualified Referrals decreased to 162.0 million in the third quarter of 2019, or by 14%, compared to 189.1 million in the third quarter of 2018.
Consolidated Revenue per Qualified Referral ("RPQR") improved significantly, reaching €1.53 in the third quarter of 2019, up 16%, compared to the same period in 2018.
Consolidated Return on Advertising Spend ("ROAS") declined to 122.8% in the third quarter of 2019, compared to 135.9% in the same period in 2018.
Net income in the third quarter of 2019 was €0.3 million, compared to €10.1 million in the third quarter of 2018.
Adjusted EBITDA(1) was €10.9 million in the third quarter of 2019, compared to €26.6 million in the third quarter of 2018.
Reflecting our performance through the third quarter of 2019, we continue to expect our Adjusted EBITDA for 2019 to be between €60 million and €80 million.

Business Overview
Marketing
We believe that building and maintaining our brand and clearly articulating our role in travelers' hotel and other accommodation discovery journey will continue to drive both travelers and advertisers to our platform to connect in a mutually beneficial way. We focus the efforts of our marketing teams and Advertising Spend towards building effective and efficient messaging for a broad audience. The amount and nature of our Advertising Spend varies across our geographic markets, depending on multiple factors including the emphasis we wish to place on profitability versus traffic growth, cost efficiency, marginal effectiveness of our Advertising Spend, local media dynamics, the size of the market and our existing brand presence in that market. We continue to optimize our Advertising Spend by tracking how likely a user that comes to us from a channel is to book a hotel with an advertiser and thereby focusing on traffic quality instead of volume.

Brand marketing
To grow brand awareness and increase the likelihood that users will visit our websites and use our apps, we invest in brand marketing globally across a broad range of media channels, including TV marketing and online video advertising.

We also generate travel content as a means of engaging with travelers, which is distributed online via social media and our online magazine. Mobile app marketing remains important given the high usage of that device type.

Performance marketing
We market our services and directly acquire traffic for our websites by purchasing travel and hotel-related keywords from general search engines and through advertisements on other online marketing channels. These activities include advertisements through search engines, such as Bing, Google, Naver and Yahoo! (commonly referred to as Search Engine Marketing, or SEM), and through display advertising campaigns on advertising networks, affiliate websites, social media sites and email marketing (commonly referred to as Display, Email and Affiliate Advertising, or DEA).

Advertiser relations
Our advertiser relations team seeks to provide tailored advice to each of our existing and prospective online travel agencies ("OTAs"), providers of alternative accommodation, hotel chains 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 help them optimize their outcomes from the trivago platform and provide guidance on additional tools and features that could further enhance advertisers’ experience. We aim to remain in close dialogue with OTAs and hotel chains to better understand each advertiser’s specific needs and objectives in order to offer optimal solutions through our marketplace.

Our advertisers include:

OTAs, including large international players, such as brands affiliated with Expedia Group, Inc. ("Expedia Group") and Booking Holdings, Inc. ("Booking Holdings"), as well as smaller, regional and local OTAs;
Hotel chains, including large multi-national hotel chains and smaller regional chains;
Individual hotels; and
Providers of alternative accommodation, such as vacation rental or apartments.

3




We generate the large majority of our revenue from OTAs. For brands affiliated with Expedia Group, including Brand Expedia, Hotels.com, HomeAway, Orbitz, Travelocity, Hotwire, Wotif and ebookers, the share of our total revenue was 32% and 34% in the third quarter of 2019 and in the nine months ended September 30, 2019, respectively, compared to 32% and 36% in the same periods in 2018. For brands affiliated with Booking Holdings, including Booking.com and Agoda, the share of our total revenue was 43% and 40% in the third quarter of 2019 and in the nine months ended September 30, 2019, respectively, compared to 44% and 40% in the same periods in 2018.

Marketplace
We design our algorithm to showcase the hotel room and other accommodation 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 booking conversion, which we describe in more detail below, 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 and other accommodation offers is our auction platform, which we call our marketplace. With our marketplace, we provide advertisers a competitive forum to access user traffic by facilitating a vast quantity of auctions on any particular day. Advertisers do this by submitting hotel room and other accommodation rates on our marketplace and cost-per-click, or CPC, bids for each user click on an advertised rate for a hotel or other accommodation. By clicking on a given rate, an individual user is referred to that advertiser’s website where the user can complete the booking. Advertisers can submit and adjust CPC bids on our marketplace frequently - as often as daily - on a property-by-property and market-by-market basis, and provide us with information on hotel room and other accommodation rates and availability on a near real-time basis. In addition, we have rolled out more granular bidding, such as bidding according to time-to-travel and length of stay, which we refer to as "bid modifiers".

In determining the prominence given to offers and their placement in our search results, including in comparison search results for a given location and on detail pages for a given property, our proprietary algorithm considers a number of factors in a dynamic, self-learning process. These include (but are not limited to) the advertiser’s offered rate for the hotel room or other accommodation, the likelihood the offer will match the user’s accommodation search criteria, data we have collected on likely booking conversion and the CPC bids submitted by our advertisers. In addition, we continue to roll out a rate accuracy score, which is based on a check of the accuracy of hotel and accommodation rates delivered to us compared to those displayed on our advertisers' platforms and which operates as an upward or downward adjustment of advertisers' CPCs in our algorithm. We are continuously optimizing our proprietary algorithm through initiatives such as the rate accuracy score to promote an experience on our website that we believe is optimal for our users. In this context, we have recently been working with our largest advertisers on a large, multi-market test to help us better understand the end-to-end impact of the relevance assessment on our users’ experience as they discover and book accommodations. After jointly analyzing the test results, we decided to phase out the aspect of our algorithm that adjusts CPC bids based on the relevance assessment. We intend to continue to cooperate closely with our advertisers to promote a seamless user experience across platforms.

We believe the most influential factors impacting bidding behavior for our largest advertisers is the rate at which our Qualified Referrals result in bookings on their websites, or booking conversion, and the amount our advertisers obtain from Qualified Referrals as a result of hotels and other accommodation booked on their sites, or booking value. We refer to the degree to which we are able to capture our share in the overall estimated booking revenues generated by our advertisers from our referrals as "commercialization". The quality of the traffic we generate for our advertisers increases when aggregate booking conversion and/or aggregate booking value increases. We estimate overall booking conversion and booking value from data voluntarily provided to us by certain advertisers to better understand the drivers in our marketplace, and in particular, to gain insight into how our advertisers manage their advertising campaigns. The information we used as the basis for our analysis of the quality of the traffic we referred to our advertisers is subject to a number of uncertainties, including those related to the
4




accuracy of the information we receive from certain of our advertisers and the methodologies we and our advertisers use to track and analyze whether a user ultimately completes a booking. Additional uncertainty may arise when the relative revenue share of advertisers providing this information changes compared to those that do not.

Assuming unchanged dynamics in the market beyond our marketplace, we would expect that the higher the potential booking value or conversion generated by a Qualified Referral and the more competitive the bidding, the more an advertiser is willing to bid for a hotel advertisement on our marketplace. This means that the levels of advertisers' CPC bids generally reflect their view of the likelihood that each click on an offer will result in a booking by a user. We believe our product optimization measures have contributed to continuous improvement in our referred traffic quality, which has had a positive effect on our Revenue per Qualified Referral, or "RPQR" in the third quarter of 2019. However, the dynamics in the market beyond our marketplace are not static, and we believe that our advertisers continuously review their Advertising Spend on our platform and on other advertising channels, and continuously seek to optimize the allocation of their spend among us and our competitors.

In addition, changes in foreign exchange rates can amplify or mute changes in these underlying trends in our revenues and RPQR. Although we largely denominate our CPCs in euro and have relatively little direct foreign currency translation with respect to our revenue, we believe that our advertisers’ decisions on the share of their booking revenues they are willing to pay to us are based on the currency in which the hotels being booked are priced. Accordingly, we have observed that advertisers tend to adjust their CPC bidding based on the relative strengthening or weakening of the euro as compared to the local functional currency in which the booking with our advertisers is denominated.

Search platform
We believe that we are reshaping hotel and accommodation discovery for our users, while changing the way advertisers identify, engage with and acquire travelers. Our search platform provides a globally standardized product for users in all segments and forms the core of our user experience. As we provide a search website, users do not book directly on our platform. When they click on an offer for a hotel room or other accommodation at a certain price, they are referred to our advertisers' websites where they can complete their booking.

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.

With the intention of increasing user retention and booking conversion, while reducing the number of click-outs required to ultimately make a booking, we continue to implement measures aimed at optimizing our platforms and product. We believe these relatively small, incremental changes to our product have resulted, when considered together, in improvements to our product and platforms that continue to positively impact our advertisers' CPC bids on our marketplace. Since we make these changes by optimizing for traffic quality instead of volume, these changes could have had a negative impact on Qualified Referrals (in addition to the effect of reduced Advertising Spend), but we believe they have had a positive impact on RPQR.

Recent trends
In the third quarter of 2019, Referral Revenue and profitability declined compared to the same period in 2018. Declines in Referral Revenue in Europe and RoW were significantly offset by an increase in Referral Revenue in Americas compared to the same period in 2018. Our Return on Advertising Spend ("ROAS") declined across all segments compared to the same period in 2018. The decline was particularly pronounced in Developed Europe and RoW. Despite the decline in Referral Revenue, we also observed the fourth consecutive quarter with period-over-period improvement in RPQR, which reflected the continued improvement in the traffic quality we referred to our advertisers.

In Americas, where we observed evidence of attractive marginal returns from our investment in marketing activities, Referral Revenue grew significantly as we increased our Advertising Spend across all marketing channels in that segment during the peak summer travel season. In Developed Europe, Referral Revenue was negatively impacted by a general softness in CPC bids of our largest advertisers during the peak summer travel season, which contributed to volatility in CPC bids in that segment. In RoW, volume levels were subdued, resulting in a decline in Referral Revenue in that segment. We believe our performance in RoW was also negatively impacted by our relatively shorter operational history and younger brand in that segment, which in turn amplified the effect of year-on-year reductions in Advertising Spend on ROAS.

The advertising bidding dynamics on our marketplace in the third quarter of 2019 were impacted by increased volatility in our marketplace as we continued to roll out bid modifiers (described above), as advertisers needed time to adjust their CPC bids to the new bidding parameters. We also phased out the relevance assessment.

Reflecting our performance in the nine months ended September 30, 2019, we continue to expect Adjusted EBITDA for 2019 to be between €60 million and €80 million.

Operating Metrics
We earn substantially all of our revenue when users of our websites and apps click on hotel offers or advertisements in our search results and are referred to one of our advertisers. We call this our Referral Revenue. 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.

Referral Revenue, Other Revenue, Qualified Referrals & RPQR

Referral Revenue by Segment & Other Revenue (€ millions)
Management has identified three reportable segments, which correspond to our three operating segments: the Americas, Developed Europe and RoW. 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 RoW segment is comprised of all other countries, the most significant by revenue of which are Australia, Japan, India, Turkey and Israel.

Total revenue decreased by €3.4 million, or by 1%, during the third quarter of 2019, compared to the same period in 2018. Total revenue decreased by €65.5 million, or by 9%, during the nine months ended September 30, 2019, compared to the same period in 2018. In the third quarter of 2019 and the nine months ended September 30, 2019, Referral Revenue continued to be negatively impacted by a decline in Qualified Referrals, which was partly offset by an increase in RPQR. In addition, a loss of revenue of €1.0 million due to the financial distress of some of our advertisers further lowered Referral Revenue and profitability in the third quarter of 2019.

Referral Revenue in the third quarter of 2019 increased to €96.3 million, or by 19% in Americas, while Referral Revenue decreased to €104.2 million and €46.7 million, or by 9% and 16% in Developed Europe and RoW, respectively, compared to the same period in 2018.

In Americas, we observed a significant improvement in RPQR and a slight decline in Qualified Referrals. The strong Referral Revenue growth in Americas was driven by an increase in Advertising Spend in this segment and improved RPQR. In Developed Europe, Referral Revenue growth was negatively impacted by a general softness in CPC bids of our largest advertisers during the peak summer travel season, which contributed to volatility in CPC bids in that segment. In RoW, Referral Revenue was negatively impacted by subdued volumes.

Referral Revenue in the nine months ended September 30, 2019, decreased to €249.2 million, €287.5 million and €135.4 million, or by 5%, 8% and 17%, in Americas, Developed Europe and RoW, respectively, compared to the same period in 2018. In each of our segments, Referral Revenue was negatively impacted by a decline in Qualified Referrals, which was partly offset by an increase in RPQR. The decline in Americas was the least pronounced among our segments due to significantly increased RPQR and a period-over-period increase in Advertising Spend in Americas in the third quarter of 2019,

which partly offset the period-over-period decline in Qualified Referrals in the first half of 2019. The decrease in Referral Revenue in Developed Europe was driven by a significant decline in Qualified Referrals, which was partly offset by an increase in RPQR particularly in the first half of 2019. In RoW, the decrease in Referral Revenue was driven by a significant decline in Qualified Referrals while RPQR only slightly improved.

Other revenue decreased by 3% to €3.1 million in the third quarter of 2019, compared to €3.2 million in the same period in 2018, mainly driven by a decrease in subscription revenue, which was partly offset by an increase in related party revenue. In the nine months ended September 30, 2019, other revenue slightly decreased by 2% to €10.4 million, compared to the same period in 2018, mainly due to a decrease in subscription revenue, which was partly offset by an increase in related party revenue and royalties.

In the third quarter of 2019, total Qualified Referrals decreased by 14% as Qualified Referrals decreased by 2%, 14% and 22% in Americas, Developed Europe and RoW, respectively, compared to the same period in 2018. The period-over-period declines in Qualified Referrals were primarily driven by ongoing Advertising Spend and product optimizations. In Americas, those negative impacts were mostly offset by the positive impact of increased Advertising Spend.

In the nine months ended September 30, 2019, Qualified Referrals decreased by 24% as Qualified Referrals decreased by 23%, 22% and 27% in Americas, Developed Europe and RoW, respectively, compared to the same period in 2018. The period-over-period decline in Qualified Referrals was broadly similar among all segments. The decline in Americas and Developed Europe was primarily driven by our ongoing optimizations of Advertising Spend and our product, while the decline in RoW was primarily driven by significant reduction in Advertising Spend in the first half of 2019.

Revenue Per Qualified Referral (RPQR)
We use 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 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.

In the third quarter of 2019, Consolidated RPQR increased by 16% as RPQR increased by 22%, 6% and 8% in Americas, Developed Europe and RoW, respectively, compared to the same period in 2018. The increase was mainly driven by improved traffic quality in all segments, especially in Americas. In Developed Europe, the RPQR development was negatively impacted by a general softness in CPC bids of our largest advertisers during the peak summer travel season. In RoW, the improvement in traffic quality was least pronounced.

In the nine months ended September 30, 2019, Consolidated RPQR increased by 20% as RPQR increased by 22%, 19% and 12% in Americas, Developed Europe and RoW, respectively, compared to the same period in 2018.

In Developed Europe, the RPQR development was negatively impacted by a general softness in CPC bids of our largest advertisers during the peak summer travel season.

Return on Advertising Spend
We track the ratio of our Referral Revenue to our Advertising Spend, or ROAS. We believe that ROAS is an indicator of the efficiency of our advertising and it is our primary operating metric.

The following table sets forth the ROAS for our reportable segments for the periods indicated:

In the third quarter of 2019, Consolidated ROAS decreased to 122.8%, compared to 135.9% in the same period in 2018. ROAS deceased by 12.0 ppts, 14.4 ppts and 13.7 ppts in Americas, Developed Europe and RoW, respectively, compared to the same period in 2018. The decrease in ROAS in Developed Europe and RoW was primarily driven by a decrease in Referral Revenue as described above. In Americas, the increase in Advertising Spend had a negative impact on ROAS in this segment, as well as on Consolidated ROAS.

In the nine months ended September 30, 2019, Consolidated ROAS improved to 129.0%, compared to 116.8% in the same period in 2018. ROAS improved by 9.8 ppts, 8.5 ppts and 17.0 ppts in Americas, Developed Europe and RoW, respectively, compared to the same period in 2018. As we continued to optimize our Advertising Spend, we observed positive period-over-period improvement in ROAS across all segments. The increase in ROAS was primarily driven by significant period-over-period improvement in ROAS in the first half of 2019, while it was partly offset by a period-over-period decline in ROAS in the third quarter of 2019, as discussed above. The significant improvement in ROAS in the first half of 2019 was driven by a significant period-over-period reduction in Advertising Spend across all segments compared to the first half of 2018 as our optimization of Advertising Spend only began to have an impact starting late in the second quarter of 2018.

Cost of revenue
In the third quarter of 2019, cost of revenue increased by €1.2 million to €2.6 million, or 86%, period-over-period, and in the nine months ended September 30, 2019 increased by €2.1 million to €6.5 million, or 48%, period-over-period, mainly due to an increase in costs for third-party cloud-related service providers.

Selling and marketing
Selling and marketing expense was 85% of total revenue in the third quarter of 2019, compared to 80% in the same period in 2018.

In the third quarter of 2019, selling and marketing expense increased by €8.8 million, or by 4%, period-over-period to €213.0 million, of which €201.3 million, or 95%, was Advertising Spend. Advertising Spend in Americas and Developed Europe increased to €77.9 million and €76.8 million respectively, compared to €59.6 million and €76.3 million, respectively, in the same period in 2018. In RoW, Advertising Spend decreased slightly to €46.6 million,compared to €48.5 million in the same period in 2018.

In the third quarter of 2019, we increased our Advertising Spend in Americas by 31% as we observed evidence of attractive marginal returns from our investment in marketing activities in that segment. In Developed Europe and RoW, Advertising Spend was at a broadly similar level compared to that in the same period in 2018.

In the nine months ended September 30, 2019, selling and marketing expense decreased by €130.7 million, or by 19%, period-over-period to €557.2 million, of which €521.0 million, or 94%, was Advertising Spend. The decrease was driven by reductions in Advertising Spend to €199.4 million, €200.1 million and €121.5 million in Americas, Developed Europe and RoW, respectively, compared to €227.7 million, €230.7 million and €173.2 million, respectively, in the same period in 2018.

We continued to optimize our Advertising Spend across all segments and all marketing channels in order to improve our ROAS, primarily in the first half of 2019. In the nine months ended September 30, 2019, the decrease in Americas was due to a significant reduction in Advertising Spend in the first half of 2019 which was partly offset by a significant increase in the third quarter of 2019. The decrease in Developed Europe was due to a reduction in Advertising Spend in the first half of 2019. The decrease was most pronounced in RoW primarily due to a continued reduction in Advertising Spend in this segment throughout the nine months ended September 30, 2019.

In the third quarter of 2019, other selling and marketing expense excluding share-based compensation decreased by €7.9 million to €11.2 million, or 41%, period-over-period, and in the nine months ended September 30, 2019, it decreased by €19.4 million to €34.3 million, or 36%, period-over-period. The decrease was primarily driven by lower investments in the production of television advertisements of €5.0 million and €8.2 million, respectively, and by a reduction in personnel costs of €3.0 million and €10.0 million during the third quarter of 2019 and the nine months ended September 30, 2019, respectively, as our headcount decreased compared to the same periods in 2018. The decrease was also driven by lower telecommunication and service fees compared to the same periods in 2018 and higher depreciation in 2018, which was partly offset by additional advertising taxes in certain geographic markets in 2019.

Share-based compensation decreased by €0.3 million to €0.5 million in the third quarter of 2019 and decreased by €0.7 million to €1.9 million in the nine months ended September 30, 2019 compared to the same periods in 2018.

12




Technology and content
For the third quarter of 2019, technology and content expense increased by €0.4 million to €17.5 million, or 2%, period-over-period, and for the nine months ended September 30, 2019, it increased by €4.0 million to €53.6 million, or 8%, period-over-period. The increases were partly driven by an increase in personnel costs of €0.5 million in the third quarter of 2019 and €1.5 million in the nine months ended September 30, 2019, compared to the same periods in 2018. The increase in personnel costs was driven by higher compensation expense and related social security amounts and by a reduced capitalization of our developers' salaries in the first half of the year 2019. Our office expense increased by €0.3 million and €1.5 million in the third quarter of 2019 and in the nine months ended September 30, 2019, respectively, as we moved into our new campus in June 2018. In the nine months ended September 30, 2019, decreases of our external content development costs were fully offset by higher third-party IT service provider costs due to increased cloud-related and data center expense. Share-based compensation decreased by €0.4 million in the third quarter of 2019 and increased by €1.2 million in the nine months ended September 30, 2019.

General and administrative
For the third quarter of 2019, general and administrative expense increased by €1.7 million to €14.4 million, or 13%, period-over-period, and for the nine months ended September 30, 2019, decreased by €4.8 million to €38.0 million, or 11%, period-over-period. The increase in the third quarter of 2019 was driven by an increase in professional fees and other expenses of €0.8 million compared to the same period in 2018, primarily due to an increase in charitable contributions and in legal, consulting and audit expense. Share-based compensation increased by €0.7 million to €3.7 million, and personnel costs increased by €0.2 million compared to the same period in 2018. The decrease in the nine months ended September 30, 2019 was driven by a decrease in professional fees and other expenses of €4.1 million compared to the same period in 2018, resulting primarily from a decrease in legal, consulting and audit expense, the impairment of internal-use software in the second quarter of 2018 and taxes withheld in foreign jurisdiction reclassified in the fourth quarter of 2018. This was partly offset by non-recurring adjustments in 2018 relating to losses on receivables and insurance expenses, and by higher charitable contributions in 2019. In the nine months ended September 30, 2019, our personnel costs decreased by €0.6 million as our headcount was lower compared to the same period in 2018, and share-based compensation decreased by €0.1 million to €8.8 million.

trivago Campus
We moved into our new campus in Düsseldorf in June 2018. The contractual lease agreements triggered build-to-suit treatment under U.S. GAAP, and the move-in triggered a sale and subsequent leaseback transaction. Upon adoption of the new leasing standard, ASC 842, on January 1, 2019, the contractual lease obligation was transitioned to being accounted for as an operating lease.

Prior to 2019, our lease payments relating to the premises were bifurcated into a portion allocated to the building (a reduction of the financing obligation) and a portion allocated to the land on which the building was constructed, which was treated as an operating lease that commenced in July 2015. Under ASC 842, a right-of-use asset and related operating lease liability are recorded on our balance sheet at September 30, 2019. Our associated lease expense is allocated across our operating cost categories.

Amortization of intangible assets
Amortization of intangible assets remained unchanged at €0.4 million during the third quarter of 2019, compared to the same period in 2018. These amortization costs relate predominantly to intangible assets recognized by Expedia Group upon the acquisition of a majority stake in trivago in 2013, which were allocated to trivago.

13




Share-based compensation
Share-based compensation decreased by €0.1 million to €5.3 million in the third quarter of 2019 and increased by €0.5 million to €15.7 million in the nine months ended September 30, 2019, compared to the same periods in 2018.

(1) “Adjusted EBITDA” (Adjusted Earnings Before Interest, Taxes, Depreciation, Amortization and Share Based Compensation) is a non-GAAP measure. Please see “Definitions of Non-GAAP Measures” and “Tabular Reconciliations for Non-GAAP Measures” on pages 23 to 24 herein for explanations and reconciliations of non-GAAP measures used throughout this release.

Net income decreased by €9.8 million to €0.3 million in the third quarter of 2019, but increased by €46.5 million to €14.0 million in the nine months ended September 30, 2019, compared to the same periods in 2018. In the third quarter of 2019, our profitability decreased due to a decline in ROAS, which was particularly pronounced in Developed Europe and RoW.

The increase in profitability in the nine months ended September 30, 2019, compared to the same period in 2018, reflects a significant increase in our marketing efficiency as we reduced our Advertising Spend to adapt to the changing dynamics on our marketplace, especially in the first half of the year 2019.

Accordingly, Adjusted EBITDA decreased by €15.7 million to €10.9 million in the third quarter of 2019 and increased by €63.3 million to €50.3 million in the nine months ended September 30, 2019, compared to the same periods in 2018.

Income taxes
Income tax expense was €2.4 million in the third quarter of 2019, compared to an income tax expense of €7.1 million in the same period in 2018. The total weighted average tax rate was 30%, which was mainly driven by the German statutory rate of approximately 31%. Our effective tax rate was 91.7% compared to 41.6% in the third quarter in 2018. Of the 91.7% effective tax rate in the third quarter of 2019, 61.7% was attributable to the impact of share-based compensation expense, which is non-deductible for tax purposes.

14




In the nine months ended September 30, 2019, income tax expense was €12.9 million compared to an income tax benefit of €6.8 million in the same period in 2018. Our effective tax rate was 48.3% compared to 17.4% in the same period in 2018. The effective tax rates for the nine months ended September 30, 2019 and 2018 were mainly due to the effect of share-based compensation expenses.

An uncertain tax position in connection with unrecognized tax benefits relating to the deductibility of expenses from prior periods amounted to €0.7 million as of September 30, 2019. A liability for these tax benefits was included under other long-term liabilities in the consolidated interim financial statements. If recognized in 2019, these tax benefits would affect our effective tax rate for the third quarter of 2019 by a negative 26.8% (i.e., a tax benefit).

Balance sheet and cash flows
Total cash, cash equivalents and restricted cash were €198.1 million as of September 30, 2019, of which €195.8 million were included in current assets and €2.3 million of long-term restricted cash were included in other long-term assets in the balance sheet primarily relating to the new campus building, compared to total cash, cash equivalents and restricted cash of €164.3 million as of December 31, 2018. The increase of €33.8 million was mainly driven by €49.8 million of positive cash flows from operating activities, which were mainly due to positive effects from net income excluding non-cash expenses.

The positive development of net cash provided by operating activities was driven by net income of €14.0 million including non-cash expenses for share-based compensation of €15.7 million and depreciation of €7.5 million.

Changes in operating assets and liabilities further contributed to an increase in cash and cash equivalents of €8.6 million primarily due to increasing accounts payable. Accounts payable increased by €15.5 million compared to December 31, 2018, primarily due to an increase in Advertising Spend from €100.9 million in the fourth quarter of 2018 to €201.3 million in the third quarter of 2019. Accounts receivable increased slightly by €2.3 million to €96.9 million as of September 30, 2019 compared to December 31, 2018.

Negative cash flows from investing activities were €16.3 million, which primarily related to capital expenditures including internal-use software and website development.

Our current ratio decreased from 4.4 as of December 31, 2018 to 4.2 as of September 30, 2019 as the increase in our current liabilities, driven by the increase in accounts payable, was higher than the increase in our current assets.

Update on legal proceedings
On August 23, 2018, the Australian Competition and Consumer Commission, or ACCC, instituted proceedings in the Australian Federal Court against us. The ACCC alleged breaches of Australian consumer law 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. A trial regarding liability was held in September 2019, and the court’s decision will be forthcoming. After that decision is rendered, the court will set a date for a separate trial regarding any potential penalty. Management has established a provision in respect of this matter.

15




A consolidated class action is pending against us in the United States District Court for the Southern District of New York alleging securities law violations in our IPO registration statement and certain later disclosures. On February 26, 2019, the court granted the motion to dismiss as to all defendants, without granting plaintiffs leave to further amend the complaint. Oral arguments regarding plaintiffs’ pending appeal of this decision are scheduled to be held on December 2, 2019 before the United States Court of Appeals for the Second Circuit.

The outcomes of these matters could have a material adverse effect on our business, financial condition or results of operations.

Earnings per Share and Ownership of the Company
Basic and diluted earnings per share of common stock is computed by dividing net income by the weighted average number of Class A and Class B shares outstanding during the period.

The following table presents our basic and diluted earnings per share:

(1) Basic net income (loss) per common share is computed by dividing (A) net income (loss) by (B) basic weighted average common shares outstanding.
(2) Diluted net income (loss) per common share is computed by dividing (A) net income (loss) (B) the diluted weighted average common shares outstanding, which has been adjusted to include potentially dilutive securities. Diluted net income (loss) per common share for the comparative period ended September 30, 2018 does not include the effects of the exercise of then-outstanding stock options as the inclusion of these instruments would have been anti–dilutive.

Notes & Definitions:

Current Ratio: The current ratio is used to measure the company´s ability to pay off its short-term liabilities with its current assets and is an important measure of liquidity. The current ratio is calculated by dividing the company´s total current assets by the company´s total current liabilities.

Referral Revenue: We use the term “referral” to describe each time a visitor to one of our websites or apps clicks on a hotel offer or advertisement in our search results and is referred to one of our advertisers. We charge our advertisers for each referral on a cost-per-click (CPC) basis.

ROAS: The ratio of our Referral Revenue to our Advertising Spend in a given period, or return on Advertising Spend. We invest in multiple marketing channels, such as: TV; out-of-home advertising; search engine marketing; display advertising campaigns on advertising networks, affiliate websites, social networking sites and email marketing; online video; mobile app marketing and content marketing.

RPQR: We use average revenue per Qualified Referral, 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.

Qualified Referral: 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.

Definitions of Non-GAAP Measures
Adjusted EBITDA:
We define adjusted EBITDA as net income (loss):

1.Less: income/(loss) from equity method investment
2.Plus: expense/(benefit) for income taxes,
3.Plus: total other (income)/expense, net,
4.Plus: depreciation of property and equipment, including amortization of internal use software and website development
5.Plus: amortization of intangible assets and
6.Plus: 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 U.S. GAAP in such company’s financial statements. We present this non-GAAP financial measure because it is used by management to evaluate our operating performance, formulate business plans, and make strategic decisions on capital allocation. We also believe that this non-GAAP financial measure provides useful information to investors and others in understanding and evaluating our operating performance and consolidated results of operations in the same manner as our management and in comparing financial results across accounting periods.


23




Our use of adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results reported in accordance with U.S. GAAP, including net 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 are not able to provide a reconciliation of our adjusted EBITDA guidance to net income/(loss), the comparable GAAP measure, because certain items that are excluded from adjusted EBITDA cannot be reasonably predicted or are not in our control. In particular, we are unable to forecast the timing or magnitude of share-based compensation, interest, taxes, depreciation and amortization without unreasonable efforts, and these items could significantly impact, either individually or in the aggregate, net income/(loss) in the future.

This release contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. These statements are not guarantees of future performance. These forward-looking statements are based on management’s expectations as of the date of this release and assumptions which are inherently subject to uncertainties, risks and changes in circumstances that are difficult to predict.

In addition, any statements that refer to expectations, projections or other characterizations of future events or circumstances are forward-looking statements and may include statements relating to future revenue, expenses, margins, profitability, net income / (loss), earnings per share and other measures of results of operations and the prospects for future growth of trivago N.V.’s business.

Actual results and the timing and outcome of events may differ materially from those expressed or implied in the forward-looking statements for a variety of reasons, including, among others:

our ability to grow our revenue in future periods, or at rates deemed sufficient by the market without reducing our profits or incurring losses;
our dependence on a relatively small number of advertisers for our revenue and adverse impacts that could result from their reduced spending or changes in their bidding strategy;
factors that contribute to our period-over-period volatility in our financial condition and result of operations, and how they may negatively impact our ability to meet the financial guidance that we communicate to the market;
our dependence on general economic conditions and adverse impacts that could result from declines in travel or discretionary spending;
the effectiveness of our Advertising Spend, including as a result of increased competition or inadequate or ineffective innovation in or execution of our advertising;
the effectiveness of our measures to increase advertiser diversity on our marketplace;
increasing competition and consolidation in our industry;
our focus on hotel and other accommodations if users expect other services;
our ability to innovate and provide tools and services that are useful to our users and advertisers;
our dependence on relationships with third parties to provide us consumer reviews;
our reliance on search engines, which may change their business models or algorithms;
any inaccuracies in, or misinterpretation of, the assumptions and estimates and data we use to make decisions about our business;
changes to and our compliance with applicable laws, rules and regulations;
the impact of any legal and regulatory proceedings to which we are or may become subject;
potential disruptions in the operation of our systems, security breaches and data protection;
