Operating and Financial Review

DÜSSELDORF, GERMANY - August 5, 2025 – trivago N.V. (NASDAQ: TRVG) (the “Company”, “we,” “us,” “our,” or “trivago,”) announced financial results for the second quarter ended June 30, 2025.

Highlights:

•Total revenue grew 17% year-over-year to €139.3 million in the second quarter, driven by an 18% increase in Referral Revenue, which reached €138.5 million, compared to the same prior year period, marking our third consecutive quarter of growth.

•Second consecutive quarter achieving double-digit year-over-year Referral Revenue growth across all three reporting segments with 10% growth in Americas, 20% in Developed Europe, and 32% in Rest of World in the second quarter compared to the same prior year period, primarily driven by branded channel traffic1 growth.

•While net loss for the second quarter increased to €6.5 million, Adjusted EBITDA2 loss improved to €5.1 million, compared to the same prior year period.

•Logged-in users on our platform generated 20% of total Referral Revenue, marking a milestone that reflects the success of our initiatives to deepen user engagement and build loyalty.

•Our acquisition of Holisto Ltd. was completed on July 31, 2025, which we expect will contribute low double-digit million euro revenue to the consolidated group results in 2025.

•Double-digit total revenue growth is expected to continue for the third quarter of 2025, which would mark our third consecutive period of double-digit growth.

"I am pleased to report strong financial performance with 17% revenue growth year-over-year. This marks our third consecutive quarter of growth and second consecutive quarter of double-digit growth across all reporting segments. We achieved this accelerated growth while improving Adjusted EBITDA year-over-year. These results demonstrate that our strategic initiatives are working, our brand marketing investments are driving returns, our product improvements are converting users, and our teams are executing with excellence across the organization." said Chief Executive Officer Johannes Thomas.

"We are thrilled to report another successful quarter for trivago, marking yet another strong performance that highlights sustained growth in branded channel traffic while maintaining stable Return on Advertising Spend, reaffirming the effectiveness of our marketing strategy. With continued double-digit revenue growth, we are reiterating our full-year guidance as we focus on driving sustainable growth while being cost disciplined. We are excited to have achieved 20% of Referral Revenue from logged-in users, which underscores our progress in fostering user loyalty and engagement. The acquisition of Holisto plays a pivotal role in enhancing the user experience by expanding our trivago-branded booking funnel which will help us drive conversion rates.” said Chief Financial Officer Dr. Wolf Schmuhl.

Discussion of Results

The discussion of results should be considered together with our unaudited financial information included with this review and the periodic reports we file with the Securities and Exchange Commission, including our Annual Report on Form 20-F for the fiscal year ended December 31, 2024. Certain information and disclosures normally included in consolidated financial statements prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”) have been omitted from this review.

Recent Trends

Total revenues grew 17% year-over-year to €139.3 million in the second quarter, primarily driven by Referral Revenue of €138.5 million, which increased 18% compared to the same prior year period. The strong results represent our third consecutive quarter of revenue growth and the second consecutive quarter of achieving double-digit revenue growth across all reporting segments. Robust growth across our marketing channels and higher traffic volumes across all segments in response to our continuous strategic marketing investments were key drivers of this performance.

Branded channel traffic growth year-over-year, particularly in Developed Europe and Americas, reached and maintained double-digit levels in the second quarter, signaling our strategic brand initiatives are effectively working as planned. The strong response to our marketing efforts, particularly to our branded channel traffic investments, persisted throughout the entire second quarter, which was instrumental for the strong performance. The quarter began with robust double-digit year-over-year Referral Revenue growth across all three reportable segments, which persisted through most of the second quarter before easing in the final weeks primarily due to strong prior year comparisons, particularly driven by a strong June performance in the prior year.

During the second quarter, we continued to make targeted Advertising Spend investments, which increased 22% year-over-year, or €20.9 million, compared to the same period in 2024. We maintained a disciplined approach to our brand and performance marketing investments, focusing on long-term sustainability and profitability. Despite the increased levels of brand investments, we maintained a strong Global ROAS of 119.0%. This reflects our ability to effectively scale our marketing strategy, particularly within our branded marketing channels, while simultaneously growing our revenue baseline at profitable levels. Looking ahead, we remain focused on executing a long-term growth strategy that prioritizes sustainable, scalable results over short-term profit maximization.

Holisto Limited Acquisition

On July 31, 2025, we completed the acquisition of Holisto Limited (“Holisto”) by acquiring all remaining outstanding equity interests for approximately €22.3 million (USD 25.5 million). Holisto is an AI-driven travel technology platform that serves as a hotel rate aggregator and white-label booking engine provider. While our initial investment in Holisto of €10.2 million in July 2024, which included the direct transaction costs incurred to acquire the investment, met the criteria for an operating segment, it did not meet the quantitative thresholds to qualify as a reportable segment. Going forward, we expect Holisto to become a separate reportable segment within trivago’s consolidated financial results.

Outlook

As we enter the peak summer travel season, we see significant opportunities to scale our marketing efforts and we remain committed to pursuing promising advertising opportunities to maintain our positive momentum. We believe these initiatives will enable us to continue expanding our audience reach, driving long-term revenue growth. Advertising Spend is expected to increase further, though it remains well below historical levels, as we focus on reinvesting profits strategically to maximize return and sustain our growth trajectory. With our strong capitalization and positioning, we are well-prepared to fuel continued growth.

For the third quarter, we anticipate delivering our third consecutive quarter of double-digit revenue growth, though at a rate below the second quarter of 2025. Despite the strong prior-year comparative period in July, total revenue continued to grow at single digits year-over-year in the first weeks of the third quarter. We expect year-over-year growth rates to improve throughout the quarter, ultimately achieving double-digit growth for the full quarter. For the full year 2025, we continue to expect trivago’s total revenues percent growth to be within the mid-teens percent range year-over-year, achieving double-digit growth. We also anticipate Holisto will further contribute low double-digit million euro total revenue while continuing to operate at near breakeven levels, resulting in an immaterial impact on our Adjusted EBITDA guidance. For the full-year 2025, we aim to achieve positive Adjusted EBITDA similar to 2024.

Revenue, Advertising Spend, and Return of Advertising Spend

Referral Revenue & Other Revenue

We match our users’ searches with large numbers of hotel and other accommodation offers through 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 submit hotel room and other accommodation rates and participate in our marketplace primarily by making bids for each user click on an advertised rate for a hotel or other accommodation on a cost-per-click, or CPC, basis. We also offer the option for our advertisers to participate in our marketplace on a cost-per-acquisition, or CPA, basis.

We earn substantially all of our revenue when users of our websites and apps click on hotel and accommodation offers or advertisements in our search results and are referred to one of our advertisers, or when a user makes a booking on the advertiser's website ultimately from a referral from our platform. We call this our Referral Revenue.

Management has identified three reportable segments: Americas, Developed Europe and Rest of World (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. In the second quarter of 2025, the most significant countries by revenue in that segment were Japan, Turkey, Australia, New Zealand, and United Arab Emirates. We have also determined that our equity method investment in Holisto Ltd. has met the criteria for an operating segment, however, it does not meet the quantitative thresholds of a separate reportable segment for the three and six months ended June 30, 2025. See "Holisto Limited Acquisition" above for further details on the acquisition of Holisto in July 2025. Going forward, we expect Holisto to become a separate reportable segment within trivago’s consolidated financial results.

We also earn revenue by offering our advertisers business-to-business (B2B) solutions such as data product offerings and subscription fees earned from advertisers for the trivago Business Studio subscriptions. These revenue streams do not represent a significant portion of our total revenue.

Referral Revenue by Segment & Other Revenue (€ millions)

Three months ended June 30, Six months ended June 30,
2025 2024 Δ Δ % 2025 2024 Δ Δ % Y/Y
Americas 52.8 47.9 4.9 10% 97.7 86.0 11.7 14%

All values are in Euros.

Note: Some figures may not add up due to rounding.

Referral Revenue increased by €21.3 million and €44.5 million during the three and six months ended June 30, 2025, respectively, compared to the same periods in 2024. The increases in all segments were primarily driven by growth from branded channel traffic in response to our continuous brand marketing investments, as well as growth from other marketing channels driven by higher traffic volumes and improved booking conversion. We continue to observe overall healthy bidding dynamics on our platform compared to the same periods in 2024, particularly in Americas and Developed Europe. These increases were partly offset by the weakening of local currencies against the Euro.

Other Revenue

Other revenue decreased by €0.7 million and €1.1 million during the three and six months ended June 30, 2025, respectively, compared to the same periods in 2024, primarily due to the discontinuation of other B2B revenue sources in the middle of 2024.

Advertiser Concentration

We generate the majority of our Referral Revenue from online travel agencies, or OTAs. For brands affiliated with Expedia Group, including Brand Expedia, Hotels.com, Orbitz, Travelocity, Hotwire, Wotif, Vrbo and ebookers, the share of our Referral Revenue was 38% and 37% during the three and six months ended June 30, 2025, respectively, compared to 41% and 39% in the same periods in 2024, respectively. For brands affiliated with Booking Holdings, including Booking.com, Agoda and priceline.com, the share of our Referral Revenue was 37% and 38% during both the three and six month periods ended June 30, 2025 and 2024, respectively.

Advertising Spend

Advertising Spend is included in selling and marketing expense and consists of fees that we pay for our various marketing channels like TV, search engine marketing, display and affiliate marketing, email marketing, online video, app marketing, content marketing, and sponsorship and endorsement.

Advertising Spend by Segment (€ millions)

Three months ended June 30, Six months ended June 30,

All values are in Euros.

Note: Some figures may not add up due to rounding.

Total Advertising Spend increased by €20.9 million and €41.3 million during the three and six months ended June 30, 2025, respectively, compared to the same periods in 2024, primarily driven by continuous increases in brand marketing investments across all segments aimed at increasing the volume of direct traffic to our platforms.

Return on Advertising Spend (ROAS)

ROAS Contribution is the difference between Referral Revenue and Advertising Spend. ROAS is the ratio of Referral Revenue to Advertising Spend. We believe that both are indicators of the efficiency of our advertising. ROAS is our primary operating metric.

ROAS Contribution (in € millions) and ROAS (in %) by Segment

Global 41.0 37.8 118.6% 121.0% (2.4) ppts

All values are in Euros.

Note: Some figures may not add up due to rounding.

Global ROAS decreased by 3.7 ppts and 2.4 ppts during the three and six months ended June 30, 2025, respectively, compared to the same periods in 2024, mainly due to continuous increases in brand marketing investments across all segments with the intention of increasing the volume of direct traffic to our platforms in the long term. This was partly offset by improved performance marketing efficiency across all segments. In Developed Europe specifically, we further accelerated our brand investment in the second quarter of 2025 as a result of the observed strong results from the brand investments in the first quarter of 2025. The higher ROAS in the first quarter of 2025 compared to the same period in 2024 largely offset the effect of increased spend in the second quarter of 2025, resulting in an overall ROAS improvement for the six months ended June 30, 2025 in Developed Europe.

Cost of Revenue

Cost of revenue remained stable during the three months ended June 30, 2025, while it decreased by €0.3 million during the six months ended June 30, 2025, compared to the same periods in 2024. The decrease during the six months ended June 30, 2025 was primarily due to a reduction of certain IT and cloud-related service provider costs that are closely related to revenue generation.

Selling and Marketing

Selling and marketing expense increased by €21.8 million and €43.1 million during the three and six months ended June 30, 2025, respectively, compared to the same periods in 2024. Of the total selling and marketing expenses, Advertising Spend represented 94% for both the three and six months ended June 30, 2025. See "Advertising Spend" above for further details.

Other selling and marketing expense increased by €0.9 million and €1.8 million during the three and six months ended June 30, 2025, respectively, compared to the same periods in 2024. The increases were primarily driven by higher television advertisement production costs, increased costs to market our platform to new hoteliers, higher digital services taxes, and increased personnel costs mainly due to a higher compensation base resulting from our annual salary review process. These increases were partly offset by the non-recurrence of the recognition of retroactive Canadian digital services taxes in the second quarter of 2024, as well as lower marketing expenses due to the end of our long-term sponsorship agreement in June 2024.

Canadian digital services taxes have been recognized quarterly since the second quarter of 2024 with retroactive effect from January 1, 2022. While the intention to rescind Canada's Digital Services Tax Act has been announced, the legislation has not been finalized. If the legislation is enacted, it will result in a cumulative accrual release of €1.1 million as of June 30, 2025.

Technology and Content

Technology and content expense decreased by €0.3 million and increased by €0.6 million during the three and six months ended June 30, 2025, respectively, compared to the same periods in 2024.

The decrease during the three months ended June 30, 2025 was primarily driven by lower non-core cloud-related service provider costs, higher capitalization of our developers' salaries, and lower share-based compensation expense. The decrease was partly offset by higher compensation expense, mainly due to a higher headcount and compensation base resulting from our annual salary review process, compared to the same period in 2024.

The increase during the six months ended June 30, 2025 was primarily driven by higher compensation expense as noted above and headcount-based allocated office repair costs. The increase was partly offset by lower non-core cloud-related service provider costs, higher capitalization of our developers' salaries, and lower share-based compensation expense, compared to the same period in 2024.

General and Administrative

General and administrative expense decreased by €1.5 million and €2.8 million during the three and six months ended June 30, 2025, respectively, compared to the same periods in 2024. The decreases were primarily driven by lower professional fees related to our call option and equity investment in Holisto. The decrease during the three months ended June 30, 2025 was further driven by lower share-based compensation expense and legal and consulting expenses. The decrease during the six months ended June 30, 2025 was further driven by lower costs resulting from the release of prior-year accruals and lower costs related to changes in the executive leadership, partly offset by higher share-based compensation expense.

Income Taxes

Income tax benefit was €1.2 million during the three months ended June 30, 2025 compared to €2.9 million in the same period in 2024. The total weighted-average tax rate for the three months ended June 30, 2025 was 30.5%, which primarily reflects the German statutory tax rate of approximately 31.2% and the estimated permanent effects for the full year, specifically non-tax-deductible expenses and deductible taxes impacting the tax base. Our effective tax rate for the three months ended June 30, 2025 was 16.0%, compared to 37.0% in the same period in 2024. The change in effective tax rate during the three months ended June 30, 2025 compared to the same period in 2024 is primarily related to the impact of the expected pre-tax income position for the full year 2025 on the weighted average tax rate, as well as the difference in deferred tax adjustments related to temporary items between the two periods.

Income tax benefit was €3.2 million during the six months ended June 30, 2025, compared to €5.3 million in the same period in 2024. Our effective tax rate for the six months ended June 30, 2025 was 20.3%, compared to 28.5% in the same period in 2024. The difference in effective tax rate during the six months ended June 30, 2025 compared to the same period in 2024 is primarily related to the impact of the difference expected pre-tax income position for the full year 2025 on the weighted average tax rate, as well as the difference in deferred tax adjustments related to temporary items between the two periods.

The difference between the weighted average tax rate and the effective tax rate for the three and six months ended June 30, 2025 primarily relates to share-based compensation expense, which is not deductible for tax purposes.

The uncertain tax position related to unrecognized tax benefits from the deductibility of expenses was €8.8 million as of June 30, 2025. The liability associated with these tax benefits is included in accrued expenses and other current liabilities in the unaudited condensed consolidated balance sheets.

Loss from Equity Method Investments

Loss from equity method investments was €0.4 million and €1.7 million during the three and six months ended June 30, 2025, respectively, compared to €0.1 million for both the same periods in 2024. The larger losses primarily resulted from the equity method investment in Holisto completed in July 2024. See "Holisto Limited Acquisition" above for further details on the acquisition of the remaining equity interests in Holisto in July 2025.

Net Loss and Adjusted EBITDA

Net losses were €6.5 million and €14.3 million during the three and six months ended June 30, 2025, respectively, while Adjusted EBITDA losses were €5.1 million and €11.6 million, respectively. The losses were primarily a result of higher selling and marketing expenses as we invested into our brand marketing activities as part of our strategy towards long-term growth.

Balance Sheet and Cash Flows

Total cash, cash equivalents and restricted cash were €111.2 million as of June 30, 2025, compared to €134.1 million as of December 31, 2024. The decrease of €22.8 million during the six months ended June 30, 2025, was mainly driven by €20.6 million cash used in operating activities and €1.0 million cash used in investing activities.

Cash used in operating activities during the six months ended June 30, 2025 was primarily driven by the net loss of €14.3 million, mainly due to the aforementioned brand marketing investments, that was offset in part by non-cash items, including share based compensation of €3.9 million and depreciation of €2.0 million. The reduction of non-cash deferred income taxes of €3.8 million further increased the cash used in operating activities.

Consistent with our seasonal fluctuations, higher revenues in the second quarter of 2025 compared to the fourth quarter of 2024 resulted in an increase of accounts receivable by €29.0 million as of June 30, 2025 compared to December 31, 2024. Additionally, accounts payable increased by €17.5 million as of June 30, 2025 compared to December 31, 2024 resulting from higher Advertising Spend. As the magnitude of the increase in current assets mainly driven by accounts receivable was higher than the increase in current liabilities mainly driven by accounts payable, there was an overall positive net working capital of €9.6 million.

Cash used in investing activities during the six months ended June 30, 2025, was primarily driven by cash outflows of €2.1 million related to capital expenditures, including internal-use software and website development, that was partly offset by cash received from the German tax authority of €1.0 million relating to tax credits that were originally recorded in the fourth quarter of 2024.

See "Holisto Limited Acquisition" above for further details on the acquisition of the remaining equity interests in Holisto resulting in subsequent cash used in investing activities of approximately €22.3 million in July 2025.

Notes & Definitions:

Definitions of Non-GAAP Measures

Adjusted EBITDA:

We report Adjusted EBITDA as a supplemental measure to U.S. Generally Accepted Accounting Principles ("GAAP").

We define Adjusted EBITDA as net income/(loss) adjusted for:

•income/(loss) from equity method investment,

•expense/(benefit) for income taxes,

•total other (income)/expense, net,

•depreciation of property and equipment and amortization of intangible assets,

•impairment of, and gains and losses on disposals of, property and equipment,

•impairment of intangible assets and goodwill,

•share-based compensation, and

•certain other items, including restructuring, ADS cancellation fees, and significant legal settlements and court-ordered penalties.

From time to time, we may exclude from Adjusted EBITDA the impact of certain items that affect the period-to-period comparability of our operating performance.

Adjusted EBITDA is a non-GAAP financial measure. A “non-GAAP financial measure” refers to a numerical measure of a company’s historical or future financial performance, financial position, or cash flows that excludes (or includes) amounts that are included in (or excluded from) the most directly comparable measure calculated and presented in accordance with U.S. GAAP in such company’s financial statements. We present these non-GAAP financial measures because they are used by management to evaluate our operating performance, formulate business plans, and make strategic decisions on capital allocation. We also believe that these non-GAAP financial measures provide useful information to investors and others in understanding and evaluating our operating performance and consolidated results of operations in the same manner as our management, and the exclusion of certain expenses in calculating Adjusted EBITDA can provide a useful measure in comparing financial results between periods as these costs may vary independent of core business performance.

Adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results reported in accordance with U.S. GAAP, including net income/loss. Some of these limitations are:

•Adjusted EBITDA does not reflect our cash expenditures or future requirements for capital expenditures or contractual commitments;

•Adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs;

•Adjusted EBITDA does not reflect expenses, such as restructuring and other related reorganization costs;

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

•Other companies, including companies in our own industry, may calculate Adjusted EBITDA differently than we do, limiting their usefulness as comparative measures.

We periodically provide an Adjusted EBITDA outlook. We are, however, unable to provide a reconciliation of our Adjusted EBITDA outlook to net income/(loss), the comparable GAAP measure, because certain items that are excluded from Adjusted EBITDA cannot be reasonably or reliably predicted or are not in our control, including, in particular, the timing or magnitude of share-based compensation, interest, taxes, impairments,

restructuring related costs and/or significant legal settlements and court-ordered penalties without unreasonable efforts, and these items could significantly impact, either individually or in the aggregate, net income/(loss) in the future.

Safe Harbor Statement Under the Private Securities Litigation Reform Act of 1995

This review 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 review and assumptions which are inherently subject to uncertainties, risks and changes in circumstances that are difficult to predict. The use of words such as "will," “intend” and “expect,” among others, generally identify forward-looking statements. However, these words are not the exclusive means of identifying such statements. 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:

•the extent to which our strategy of increasing brand marketing investments positively impacts the volume of direct traffic to our platform and grows our revenue in future periods without reducing our profits or incurring losses;

•the continuing negative impact of having almost completely ceased television advertising in 2020 and only having resumed such advertising at reduced levels in recent years on our ability to grow our revenue;

•our reliance on search engines, particularly Google, whose search results can be affected by a number of factors, many of which are not in our control;

•the promotion by Google of its own product and services that compete directly with our hotel and accommodation search;

•our continued dependence on a small number of advertisers for our revenue and adverse impacts that could result from their reduced spending or changes in their cost-per-click, or (CPC), bidding or cost-per-acquisition (CPA) strategy;

•our ability to generate referrals, customers, bookings or revenue and profit for our advertisers on a basis they deem to be cost-effective;

•factors that contribute to our period-over-period volatility in our financial condition and result of operations;

•the potential negative impact of a worsening of the economic outlook and inflation on consumer discretionary spending;

•any further impairment of intangible assets;

•geopolitical and diplomatic tensions, instabilities and conflicts, including war, civil unrest, terrorist activity, sanctions or other geopolitical events or escalations of hostilities, such as the ongoing military conflict between Russia and Ukraine, the ongoing conflicts affecting the Middle Eastern region, potential changes in U.S. tariff policy and other countries' responses thereto, or other developments resulting in heightened cross-border controls;

•increasing competition in our industry;

•our ability to innovate, integrate, and provide tools and services that are useful to our users and advertisers;

•our business model's dependence on consumer preferences for traditional hotel-based accommodation;

•our dependence on relationships with third parties to provide us with content;

•changes to and our compliance with applicable laws, rules and regulations;

•the potential operating difficulties and other harmful consequences from the integration of acquired assets and businesses;

•the impact of any legal and regulatory proceedings to which we are or may become subject; and

•potential disruptions in the operation of our systems, security breaches and data protection,

as well as other risks and uncertainties detailed in our public filings with the SEC, including trivago's Annual Report on Form 20-F for the fiscal year ended December 31, 2024, as such risks and uncertainties may be updated from time to time. Except as required by law, we undertake no obligation to update any forward-looking or other statements in this review, whether as a result of new information, future events or otherwise.

Notes to the condensed consolidated financial statements (unaudited)

Note 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 hotel and accommodation through online travel agencies (“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 generally 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. We also offer a ‘cost-per-acquisition’ (or “CPA”) pricing structure, whereby an advertiser pays us a percentage of the booking revenues that ultimately result from a referral.

During 2013, the Expedia Group, Inc. (formerly Expedia, Inc., the "Parent" or "Expedia Group") completed the purchase of a controlling interest in the Company. As of June 30, 2025, Expedia Group’s ownership interest and voting interest in trivago N.V. is 59.3% and 84.0%, respectively.

Basis of presentation

We have prepared the accompanying interim unaudited condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial reporting. We have included all adjustments necessary for a fair presentation of the results of the interim period. These adjustments consist of normal recurring items. Our interim unaudited condensed consolidated financial statements are not necessarily indicative of results that may be expected for any other interim period or for the full year.

Certain information and note disclosures normally included in the audited annual consolidated financial statements have been condensed or omitted in accordance with SEC rules. The condensed consolidated balance sheet as of December 31, 2024 was derived from our audited consolidated financial statements as of that date but does not contain all of the footnote disclosures from the annual financial statements. As such, these interim unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes included in our Annual Report on Form 20-F for the year ended December 31, 2024, previously filed with the Securities and Exchange Commission (“SEC”).

Seasonality

We experience seasonal fluctuations in the demand for our services as a result of seasonal patterns in travel. For example, searches and consequently our revenue, are generally the highest in the first three quarters as travelers plan and book their spring, summer and winter holiday travel. Our revenue typically decreases in the fourth quarter. 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. Changes in the relative revenue share of our offerings in countries and areas where seasonal travel patterns vary from those described above may influence the typical trend of our seasonal patterns in the future.

Accounting estimates

We use estimates and assumptions in the preparation of our interim unaudited condensed consolidated financial statements in accordance with GAAP. Preparation of the interim unaudited condensed consolidated financial statements and accompanying notes requires that we make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the date of the unaudited condensed consolidated financial statements, as well as revenue and expenses during the periods reported. Our actual financial results could differ significantly from these estimates. The significant estimates underlying our interim unaudited condensed consolidated

financial statements include: leases, recoverability of indefinite-lived intangible assets, income taxes, and share-based compensation.

Note 2: Significant accounting policies

The significant accounting policies used in preparation of these unaudited condensed consolidated financial statements for the three and six months ended June 30, 2025 are consistent with those discussed in Note 2 to the consolidated financial statements in our Annual Report on Form 20-F for the year ended December 31, 2024, except as updated below.

Recent accounting pronouncements not yet adopted

Income Taxes. In December 2023, the Financial Accounting Standards Board ("FASB") issued ASU 2023-09 to improve its income tax disclosure requirements. Under the new guidance, public business entities must annually disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5 percent of the amount computed by multiplying pretax income (loss) by the applicable statutory income tax rate). The new standard is effective for fiscal periods beginning after December 15, 2024. We will incorporate the new guidance in our tax disclosures in our consolidated financial statements for the fiscal year ended December 31, 2025.

Expense Disaggregation Disclosures. In November 2024, the FASB issued ASU 2024-03 which requires enhanced disaggregated disclosures regarding income statement expenses in a tabular format. The new guidance requires relevant expense captions to be disaggregated into categories, such as employee compensation, depreciation, and intangible asset amortization, included within each interim and annual income statement's expense caption, as applicable. Additionally, entities are required to disclose their selling expenses and their definition of selling expenses. The new standard is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. We are in the process of evaluating the impact of adopting this new guidance on our consolidated financial statement disclosures.

Certain risks and 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.

Note 3: Fair value measurement

Financial assets measured at fair value on a recurring basis are classified using the fair value hierarchy in the tables below:

June 30, 2025
(in thousands) Level 2
Cash equivalents:
Term deposits 79,998
Investments and other assets:
Term deposits 1,351
Total 81,349 December 31, 2024
--- --- ---
(in thousands) Level 2
Cash equivalents:
Term deposits 80,950
Investments and other assets:
Term deposits 1,351
Total 82,301

We value our financial assets using quoted market prices or alternative pricing sources and models utilizing market observable inputs.

We hold term deposit investments with financial institutions. We classify our term deposits within Level 2 in the fair value hierarchy because they are valued at amortized cost, which approximates fair value. Term deposits with a maturity of less than 3 months are classified as cash equivalents, those with a maturity of more than three months but less than one year are classified as short-term investments and those with a maturity of more than one year are classified as investments and other assets. Investments in term deposits with a maturity of more than one year are restricted by long-term obligations related to the campus building.

Assets measured at fair value on a non-recurring basis

Our non-financial assets, such as intangible assets and property and equipment, as well as our non-marketable equity investments, including our equity method investments and investment accounted for under the measurement alternative, are adjusted to fair value when an impairment charge is recognized

or the underlying investment is sold. Such fair value measurements are based predominately on Level 3 inputs.

On April 14, 2025 and May 21, 2025, 500,000 Class A share RSUs and 1,000,000 Class A share options, respectively, were granted to our new Chief Financial Officer. The RSUs will vest in equal installments quarterly while the options will vest in equal installments annually, both over the next three years.

On May 31, 2025, 5,213,335 of the outstanding Class A share options held by our former Chief Financial Officer were forfeited in conjunction with his departure.

(1) Inclusive of 785,730 RSUs withheld due to net share settlements to satisfy required employee tax withholding requirements. Potential shares which had been convertible under RSUs that were withheld under net share settlements remain in the authorized but unissued pool under the 2016 Omnibus Incentive Plan and can be issued by the Company. Total payments for the employees' tax obligations to the taxing authorities due to net share settlements are reflected as a financing activity within the unaudited condensed consolidated statements of cash flows.

Note 7: Income taxes

Income tax benefit was €1.2 million during the three months ended June 30, 2025, compared to €2.9 million in the same period in 2024. The total weighted-average tax rate for the three months ended June 30, 2025 was 30.5%, which primarily reflects the German statutory tax rate of approximately 31.2% and the estimated permanent effects for the full year, specifically non-tax-deductible expenses and deductible taxes impacting the tax base. Our effective tax rate during the three months ended June 30, 2025 was 16.0%, compared to 37.0% in the same period in 2024. The change in effective tax rate during the three months ended June 30, 2025 compared to the same period in 2024 is primarily related to the impact of the expected pre-tax income position for the full year 2025 on the weighted average tax rate, as well as the difference in deferred tax adjustments related to temporary items between the two periods.

Income tax benefit was €3.2 million during the six months ended June 30, 2025, compared to €5.3 million in the same period in 2024. Our effective tax rate for the six months ended June 30, 2025 was 20.3% compared to 28.5% in the same period in 2024. The difference in effective tax rate during the six months ended June 30, 2025 compared to the same period in 2024 is primarily related to the impact of the expected pre-tax income position for the full year 2025 on the weighted average tax rate, as well as the difference in deferred tax adjustments related to temporary items between the two periods.

The difference between the weighted average tax rate and the effective tax rate for the three and six months ended June 30, 2025 is primarily attributable to share-based compensation expense, which is not deductible for tax purposes.

The uncertain tax position related to unrecognized tax benefits from the deductibility of expenses was €8.8 million as of June 30, 2025. The liability associated with these tax benefits is included in accrued expenses and other current liabilities in the unaudited condensed consolidated balance sheets.

Note 8: Stockholders' equity

Class A and Class B Common Stock

Our authorized share capital amounts to €234.0 million and is divided into Class A and Class B common stock with par values of €0.06 and €0.60, respectively. As stated in our articles of association, each Class B shareholder can request the conversion one or more Class B shares at any time with the ratio of one Class B share to ten Class A shares. The shareholder will then transfer nine out of every ten Class A shares to the Company for no consideration, leaving the shareholder with one issued Class A share.

Upon conversion, the number of authorized Class B shares decreases by the number converted and concurrently, the number of Class A shares increases by ten times the number of Class B shares converted in order to maintain our authorized share capital. At the time of our IPO in 2016, the number of authorized Class A and Class B shares was 700,000,000 and 320,000,000, respectively. These share counts have been adjusted accordingly with each conversion of Class B shares into Class A shares and the current share counts are reflected on the unaudited condensed consolidated balance sheets.

As of June 30, 2025, Class B shares are only held by Expedia Group and Rolf Schrömgens. Refer to Note 1: Organization and basis of presentation for Expedia Group's ownership interest and voting interest. The Class B shares held by Mr. Schrömgens as of June 30, 2025, had an ownership interest and voting interest of 8.1% and 11.4%, respectively.

The ratio of the Company's American Depositary Shares ('ADS') program is one ADS to five Class A shares.

Note 9: Earnings per share

Basic and diluted earnings per share of Class A and Class B common stock is computed by dividing net income/(loss) 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.

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

Three months ended<br>June 30, Six months ended<br>June 30,
(€ thousands, except per share data) 2025 2024 2025 2024
Numerator:
Net loss (6,502) (4,942) (14,297) (13,326)
Denominator:
Weighted average shares of Class A and Class B common stock outstanding:
Basic 351,905 348,973 351,895 349,032
Diluted 351,905 348,973 351,895 349,032
Net loss per share:
Basic (0.02) (0.01) (0.04) (0.04)
Diluted (0.02) (0.01) (0.04) (0.04)

As of June 30, 2025 and 2024, approximately 33 million of outstanding stock-based awards have been excluded from the calculations of diluted net loss per share because their effect would have been antidilutive.

Note 10: Commitments and contingencies

Legal proceeding

One purported class action has been filed in Israel, making allegations about our advertising and/or display practices, such as search results rankings and algorithms, and discount claims. A pre-trial case management hearing took place on October 1, 2024. The court ordered trivago to provide certain information to the plaintiff. Pursuant to the court's recommendation, the parties initiated mediation

procedures to evaluate possibilities for an amicable resolution of the matter in December 2024. These procedures are currently ongoing.

Note 11: Related party transactions

Relationships with Expedia

We have commercial relationships with Expedia Group, Inc. and many of its affiliated brands, including Brand Expedia, Hotels.com, Orbitz, Travelocity, Hotwire, Wotif, Vrbo and ebookers. These arrangements are terminable at will upon fourteen to thirty days prior notice by either party and on customary commercial terms that enable Expedia Group’s brands to advertise on our platform, and we receive payment for users we refer to them. We also have an agreement with Expedia Partner Solutions ("EPS"), where EPS powers our platform with a template (Hotels.com for partners). Related-party revenue from Expedia Group primarily consists of click-through fees and other advertising services provided to Expedia Group and its affiliates.

Related-party revenue from Expedia Group and its affiliates was €53.2 million and €96.6 million for the three and six months ended June 30, 2025, compared to €47.5 million and €84.5 million in the same periods in 2024, respectively. These amounts are recorded at contract value, which we believe is a reasonable reflection of the value of the services provided. Related-party revenue from Expedia Group represented 38% and 37% of our total revenue for the three and six months ended June 30, 2025, compared to 40% and 38% in the same periods in 2024, respectively.

For the three and six months ended June 30, 2025 and 2024, we did not incur significant operating expenses from related-party services and support agreements with Expedia Group.

The related party trade receivable balances with Expedia Group and its affiliates as of June 30, 2025 and December 31, 2024 were €34.0 million and €20.8 million, respectively.

UBIO Limited

Effective January 1, 2025 we renewed the commercial agreement with our existing partner UBIO Limited to increase the number of directly bookable rates available on our website for an additional 12-month period. This agreement will extend by subsequent 12 month periods, unless it is terminated by either party with 90 days prior notice at the end of each period. The agreement includes an annual minimum commitment of €0.8 million (GBP 0.7 million).

Our operating expenses related to this partner were €0.2 million and €0.4 million for the three and six months ended June 30, 2025, compared to €0.3 million and €0.7 million in the same periods in 2024, respectively.

Holisto Limited

We entered into an equity method investment in Holisto Limited ("Holisto") on July 30, 2024. Related-party revenue, consisting mainly of click-through fees from Holisto was €2.1 million and €4.6 million for the three and six months ended June 30, 2025. These amounts are recorded at contract value, which we believe is a reasonable reflection of the value of the services provided. The related party trade receivable balances with Holisto as of June 30, 2025 and December 31, 2024 were €0.7 million and €0.5 million, respectively.

Our operating expenses related to this partner were €0.2 million and €0.5 million for the three and six months ended June 30, 2025.

Note 12: Segment information

Management has identified three reportable segments: Americas, Developed Europe and Rest of World (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 where trivago operates. Our investment in Holisto met the criteria for an operating segment, however, it does not meet the quantitative thresholds of a separate reportable segment for the three and six months ended June 30, 2025. See "Note 13: Subsequent events" for further details on the acquisition of Holisto in July 2025. Going forward, we expect Holisto to become a separate reportable segment within trivago’s consolidated financial results.

Our chief operating decision makers ("CODMs") are our managing directors comprised of the Chief Executive Officer, Chief Financial Officer, Chief Marketing Officer, and Chief Product Officer. 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, ("ROAS") contribution, for each of our reportable 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.

Our CODMs use ROAS contribution to allocate resources for each reportable segment predominantly in the annual budget and forecasting process. The CODMs consider budget-to-actual variances on a monthly basis using ROAS contribution when making decisions about the allocation of Advertising Spend to the reportable segments. The CODMs also use ROAS contribution to assess the performance for each reportable segment.

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, impairment of goodwill, 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 reconciliations below.

The following tables present our segment information for the three and six months ended June 30, 2025 and 2024. 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.

Note 13: Subsequent events

On July 11, 2025, the German parliament finalized the Immediate Tax Investment Program ("Investitionssofortprogramm") which will gradually reduce the corporate income tax rate by one percentage point per year, beginning in 2028, from the current rate of 15% to 10% in 2032. As a result, we will adjust our tax calculation and record a reduction in our deferred income taxes liability by approximately €2.4 million in the third quarter of 2025.

On July 31, 2025, we completed the acquisition of Holisto by acquiring all remaining outstanding equity interests for approximately €22.3 million (USD 25.5 million). Holisto is an AI-driven travel technology platform that serves as a hotel rate aggregator and white-label booking engine provider.
