Trivago N : Q4 2020 Shareholder Letter

Exhibit 99.2
February 9, 2021

Dear shareholders,
We are writing to you at a challenging moment of the COVID-19 pandemic. The second wave has hit
many countries hard, and the death toll has risen sharply. New variants of the virus have emerged that
tend to spread faster and are more transmissible or infectious. Measures to contain the virus, including
strict lockdowns and mobility restrictions, have been reinstated in numerous countries. Citizens around
the globe are facing significant challenges and stress after many months of restrictions and travel activity
in many regions has come to an almost complete halt for the second time in one year.

Although the situation remains difficult, we are beginning to see how and when life will start getting back
to normal. We are encouraged by the start of large-scale vaccination programs in multiple countries, the
initial learnings about these programs gathered in countries like Israel and the UK, the increased
availability of testing and improvement of treatments. We believe that by the second half of the year the
return to normalcy will be underway with the COVID-19 pandemic beginning to be much more under
control than it is today. And this exact point in time is what we have been preparing for, when travel
returns and the industry begins to ramp back up.

For at least the first quarter of 2021, we expect containment measures and restrictions to continue to be
imposed across most of our major markets. In the second quarter of 2021, we expect that some
restrictions might start to be eased, but this will depend on the progress and effectiveness of the
vaccination programs, individuals' confidence in resuming travel activities and many other uncertainties.
We are optimistic that, in the second half of 2021, there will be a strong recovery in travel activities with an
initial focus of users on nature destinations which we have already observed in the summer of 2020.

Industry dynamics - changes ahead
In the fourth quarter of 2020, we observed elevated volatility in performance marketing channels including
our own auction as new mobility restrictions were imposed in some of our core markets. Our advertisers
have implemented bidding strategies that vary more than in normal times, as their expectations regarding
cancellations differ in significant respects.

For 2021, and beyond, we see changes in industry dynamics ahead of us:
• The pandemic has accelerated the shift from linear TV to digital consumption. We expect this
trend to continue. Combined with the fact that certain segments of the population will likely return
to travel at different points in time, we believe that we will need to implement a brand marketing
strategy that is more granular in approach in order to more efficiently target our customers and
continue to shape their perception of our leading online travel brand.
• Business travel continues to be heavily impacted by the pandemic and is expected to take longer
to recover than leisure travel. We expect sustainable growth in the apartment-style hotel market
and managed apartment segment and expect large hotel chains to increase their respective
offering.

There has been a very strong and noticeable shift in political and public sentiment towards big
tech. The large 'gatekeeper' platforms are subject to increased scrutiny across the globe with
concerns arising in areas such as influence of public opinion, anti-competitive behavior and data
protection. While this trend also poses the risk of triggering mistrust and skepticism about
innovation and technological progress overall, we believe that these developments will be positive
for the travel industry as these efforts have the potential to lead to a more customer-centric,
innovation-driven competitive dynamic. Recent changes to German competition law (the
amended Unfair Competition Act) has been one of the first that has come into force in this area
and not only forbids self-preferencing by gatekeeper platforms but also introduces an accelerated
process to ensure enforceability. The European Commission has released first drafts of its Digital
Markets Act and Digital Services Act which are pointing in a similar direction.

trivago in Q4 2020 and 2021
Following the reimposition of a strict lockdown in Germany in November, a key focus has been to keep up
the morale of our team. This has not been easy as 70% of our colleagues come from abroad and, just as
the weather was becoming cold and dark in Germany, many of them faced uncertainty about connecting
with their families over the holiday break. I am very proud of the work that our leads and our talent and
culture teams have done over the past few months, keeping a personal touch after almost a year of
predominantly working in a remote setup, and even increasing our employee net promoter score to preCOVID levels!
The teams share our excitement about the year ahead of us, and morale has stayed
strong.

Significant progress has been made on our key recovery initiatives, and we are confident that we will
provide our users in the second half of 2021 with a much stronger value proposition than before the
pandemic.
• A new release of our local travel product is expected to launch in the second quarter of 2021 in
key markets. It will offer inspiration about local travel destinations, reasons to travel combined
with the great deals that users are used to seeing on trivago. Our recent acquisition of
weekend.com gives us access to an inspirational weekend product and the ability to package
flights and hotels for city trips.
• We have continued to work closely with our advertisers to support them in preparing for the
recovery of travel and jointly improve our end-to-end value proposition. As a result, we have
onboarded more than 100 partners to our new products, display advertisements, sponsored
listings and our CPA bidding tool. In parallel, we managed to increase our coverage of special
and loyalty program membership rates for our users and expect coverage to continue to increase
in the months to come.
• We recently renegotiated our lease contract for the Campus in Düsseldorf and signed an
amendment to the contract, which became effective in January 2021. The agreement includes the
return of unused office space as of January 1, 2021 and a corresponding reduction of rent. As a
result of this amendment and the restructuring that we announced last year, we expect to reduce
costs in 2021 relating to personnel and our offices by approximately €25 million compared to
2019.

As we look to the months ahead, we expect the situation to remain difficult for us not only as a business
but also individually. We are nevertheless looking forward to the recovery that we expect in the second
half of 2021 and have been working towards for almost a year. Every day is bringing us closer to that
point in time.
