Good afternoon, and thank you for joining Airbnb's Earnings Conference Call for the First Quarter of 2024. As a reminder, this conference call is being recorded and will be available for replay from the Investor Relations section of Airbnb's website following this call. I will now hand the call over to Angela Yang, Director of Investor Relations. Please go ahead.

Good afternoon, and welcome to Airbnb's first quarter of 2024 earnings call. Thank you for joining us today. On the call today, we have Airbnb Co-Founder and CEO, Brian Chesky and our Chief Financial Officer, Ellie Mertz. Earlier today, we issued a shareholder letter with our financial results and commentary for our first quarter of 2024. These items were also posted on the Investor Relations section of Airbnb's website. During the call, we'll make brief opening remarks and then spend the remainder of time on Q&A. Before I turn it over to Brian, I would like to remind everyone that we will be making forward-looking statements on this call that involve a number of risks and uncertainties. Actual results may differ materially from those expressed or implied in the forward-looking statements due to a variety of factors. These factors are described under forward-looking statements in our shareholder letter and in our most recent filings with the Securities and Exchange Commission. We urge you to consider these factors and remind you that we undertake no obligation to update the information contained on this call to reflect subsequent events or circumstances. You should be aware that these statements should be considered estimates only and are not a guarantee of future performance. Also, during this call, we will discuss some non-GAAP financial measures. We provide a reconciliation to the most directly comparable GAAP financial measures in the shareholder letter posted to our Investor Relations website. These non-GAAP measures are not intended to be a substitute for our GAAP results. With that, I will pass the call to Brian.

All right. Good afternoon, everyone, and thanks for joining. Airbnb had a strong start to 2024. We had 133 million nights and experiences booked in Q1, marking our highest first quarter ever. Revenue of $2.1 billion grew 18% year-over-year, primarily driven by continued strength in travel demand and the timing of Easter. Net income was $264 million, representing a net income margin of 12%. For Q1, our free cash flow was $1.9 billion, our highest ever. And for the trailing 12 months, our free cash flow was $4.2 billion, representing a free cash flow margin of 41%. Our strong cash flow allowed us to repurchase $750 million of our shares in the quarter. And at the end of Q1, we had $6 billion remaining on our repurchase authorization. Now, during Q1, we made significant progress across our three strategic initiatives, which are making hosting mainstream, perfecting our core service, and expanding beyond the core. First, we're making hosting mainstream. We remain focused on making hosting just as popular as traveling in Airbnb. And to do this, we're raising awareness around the benefits of hosting, providing better tools, and helping hosts deliver high-quality stays. As we grow, we're also taking action to rapidly improve the quality of stays on Airbnb. In Q1, we removed thousands of listings that failed to meet our guest expectations. And excluding these removals, active listings for accommodations grew 17% year-over-year. And we also saw sustained double-digit supply growth across all regions. This year, we'll continue to raise awareness around hosting and improve the overall host experience. Second, we are perfecting our core service. Over the past few years, we've rolled out more than 430 new features and upgrades to improve our service. In November, we took another huge step forward on reliability with the launch of…

[Operator Instructions] Our first question will come from the line of Mark Mahaney with Evercore ISI. Please go ahead.

Thanks. You talk about these kind of leaning into these kind of less mature markets and this doubling of growth rate in some of those expansion markets versus your core markets. Could you give a little more color on which countries and which markets that is? Which countries, I think in the past, you may have mentioned Brazil, but which ones you're leaning into this year? And then secondly, that U.S. app downloads increase of 60% year-over-year. That's an extremely high number for what you would think would be a reasonably well-known app and brand. So what drove that? Do you have any whys behind that? Thank you very much.

Yes. Hey, Mark. Why don't I start? So leaning into less mature markets. So if you think about Airbnb, we're obviously in 220 countries and regions. We're one of the most global brands in the world. But our markets with the highest penetration would be U.S., Canada, Australia, France, and U.K. So those five. So the next markets that are the biggest potential TAM would be like Mexico, and Brazil, and Latin America. In Europe, it would be Germany. It would be Italy. It would be Spain. We're also starting to see some traction like Switzerland and Netherlands. And in Asia, it would be Japan. It would be Korea. It would be China. And eventually, a little bit longer game would be India. So these are, and there's a few others in Latin America. So I could kind of keep going. But those are kind of some of the really, really big travel TAMs. And Mark, maybe just one other thing I'll just say. I think a really good thing to look at is our penetration for each country. And while U.S., Canada, Australia are really, really similar, there's a really, really big drop off in a lot of these other markets that are huge travel TAMs, I mean, especially in Asia. And one of the things that we've learned is that Airbnb pretty much resonates pretty equally everywhere once there's the awareness. In fact, I could argue that Airbnb might resonate better in Asia because there's a younger travel population that's not predisposed to hotels and they're on social media. And we are disproportionately on social media versus our competitors. So I'm very, very bullish about that. Now, on U.S. staff downloads, you're right. I mean, it's grown 60% last year. It went from 49% of bookings to 54%…

Thank you, Brian.

Brian, if I could just add, I think the app download effort is really just part of our broader priority around perfecting the core and optimizing the core business. We identified that not as many of our guests were using the app as they should. And we know that the app is a much better user experience than MoWeb. So it's again, part of a broader suite of roadmap items that are intended to improve and perfect the core experience.

Thank you, Ellie.

Thanks, Mark.

Your next question will come from the line of Richard Clark with Bernstein. Please go ahead.

Hi, good afternoon. Thanks for my questions. Just on, you mentioned on the prepared remarks and you mentioned that Q4, that Q1 would have quite a tough comp. And there's calendar effects in there as well. But you're guiding the Q2, it's going to be flat on room night growth. So is there anything you call out in Q2 that's maybe holding that back and how we should think about the rest of the year? And maybe just a similar question on margin, the Q2 guide, I guess a little bit softer than consensus had some calendar in there. Is that including any of the growth investments you talk about or are those things that may come in more the second half of the year?

Yes, thanks, Richard. Let me just talk a little bit about the trends that we've seen here today to help answer your question. So first, as you point out, as we were heading into 2024, we were widely aware that last January was particularly strong. And so the guide that we've provided back in February included a step down in growth from Q4 to Q1 that was reflective of that hard comp from a year ago. We did experience it. And then since then, we've seen relatively stable growth, which I see as frankly, a really strong statement in terms of both the stability and resilience of leisure travel demand so far this year. I think, something that we've seen this year that is contrasting to last year there was a lot of volatility in terms of the timing of when people booked relative to their check-ins. And so far this year, it's been, frankly, much more stable. Lead times on our platform have been, frankly, generally in line with a year ago, and it just hasn't been at the same level of volatility, again, that we saw a year ago. And so heading into Q2, our guidance reflects this continued stability of booking. Obviously, we'd like to deliver higher growth and stable growth, but our outlook obviously reflects the trends that we have seen quarter to date. To your question on Q2 margins, obviously, we guided, the Q1 results reflect a pretty meaningful year-over-year margin expansion. A big portion of that is due to the timing of Easter. So Easter is not only a benefit to revenue growth in Q1, but it's obviously also a benefit to margin expansion. Those two factors reverse in Q2. It is a headwind to revenue growth, and it is a headwind to overall margins. Two other components in terms of what's putting pressure on margins in Q2. One is just some one-time credits that we had in payment processing a year ago that will not recur this year. And then third, we shifted slightly the timing of our marketing spend, a little bit heavier in Q2 than in Q1, and that will be reflected in terms of marketing as a percent of revenue growing in the quarter on a year-over-year basis.

Very helpful. Thank you.

Your next question will come from the line of Jed Kelly with Oppenheimer. Please go ahead.

Hey, great. Thanks for taking my question. Just one on ADRs. They seem to be relatively sticky, and I think a couple quarters ago, you talked about driving value to the consumer. So can you just give us an update on where you are in sort of some of your value initiatives? And then on supply, great supply growth again. Can you talk about how we should think about supply and nights eventually converging to similar growth rates? Thank you.

Yes. Hey, Jed. Why don't I take the first one on value initiatives, and I'll let Ellie take the second one. So on providing value, when we started Airbnb, our original tagline was a cheap, affordable alternative to a hotel. And the majority of the primary reason people came to us is because it was a better value than a hotel. And we still think that's a core value proposition that we have to offer. Now, a year and a half ago, we noticed that, there was a lot of concern about Airbnb prices increasing. And so we created a whole team to identify a series of initiatives to modulate our prices, and they're working. And I'll go down the list. One is total price display. So as you know, in travel, especially online travel, there's a lot of progressive fee disclosures. And we decided to have a toggle right on the homepage that you can turn on to show the total price display. Since we've done that, not only do consumers -- not only are consumers going toward the best total value, but it's begun to change behavior in our host community because 300,000 or 300,000 listeners, say, have removed or lowered their cleaning fee as a result. So that was the first thing we did. The next thing we did is we started offering monthly and weekly discounts and much more robust tools for that. Now, this is important because, nearly half of our nights booked are for stays of a week or longer. And now more than two-thirds of our hosts offer a monthly or weekly discount. We also noticed that a lot of hosts that weren't getting booked weren't getting booked because their prices were too high. And they just didn't have really good concepts. So we created a tool called the Compare Listing Tool where people can see how much other people are charging the neighborhood. And they can actually see people who are getting booked, not getting booked. And no surprise, the people getting booked generally have lower prices. We have nearly 2 million hosts that now use the Compare Listing Tool. So those are just a few of the initiatives we've done. We actually have many others as well. The net of all of it is that hotel prices are up year-over-year and Airbnb listings on a like-for-like basis are down. So today the value of Airbnb versus a hotel is better than it was a year ago. And I think that trend line is going to continue given all of our efforts. And maybe the only other thing I'll just say on this is, as we know, loss of supply and demand, as supply grows faster and demand prices go down a little bit. And supply is growing faster in demand. I think that's also relieving some pressure. Ellie, over to you.

Yes, so Jed, to your question with regard to the relative growth rates of supply and demand, just a few comments. I would say first, something that we've shared previously is that in any given quarter, we would not expect supply and demand to grow exactly in line. But when we look over a longer time period, either the last decade or more specifically from pre-pandemic to today, what we do see is that over a period of years, they do grow generally in line. And I would say that continues to be the case. Where we are right now, I would say we're very encouraged to be able to deliver this continued level of very strong supply growth for a couple of reasons. I would say one, we know that more unique, differentiated supply wins and differentiated supply is why people come to Airbnb. I would say second, and Brian made this point, but growing supply allows us to, it really benefits our affordability measures in that more supply obviously but gets more competitive pricing. And then I would say third, relevant to our recent quality initiatives, we see it as an opportunity for, as supply growth is stronger than demand growth, for us to continue to be driving quality. What you saw in the quarters, we obviously did some one-time takedowns of supply that frankly just did not meet our community's expectations. And the fact that supply is growing so rapidly, it allows us to make those cuts, if you will, to the supply base and to be continually upgrading the level of quality that we deliver to our guests.

Thank you.

Your next question comes from the line of Ron Josey with Citi. Please go ahead.

Great, thanks for taking the question. Brian, I wanted to ask you about search on Airbnb, just following the strength and the benefits of guest favorites. I wanted to better understand sort of, talk to us about post-guest favorites, how search and really conversion rates have improved and really how you feel search can just evolve over time. And then as a follow-up to what we were just talking about around inventory quality, we'd love to hear just the process to ensure that quality listings continue to come on the platform. I think we've talked about verified listings and trophies, but any other thoughts there would be helpful. Thank you.

Oh yes, Ron. These are really, really good questions, Ron. So yes, let's start with search. So, we did approximately $10 billion last year in revenue. So the way to think about this is if we can just drive an incremental 100 basis points in growth, that's $100 million. So like the way we look at our conversion rate is like we have teams dedicated to the search experience. And we, over the last year, we, the last 12 months, we've likely driven at least a few 100 basis points of incremental growth just through optimizations of the search flow, because we just get so much traffic. And so just to call out a couple of things that we did, I mean, there's been dozens of dozens, I'll just name a couple. One I already mentioned, mobile app downloads. Now, why do mobile app downloads lead to also more bookings? Because the conversion rate on a native application is typically a lot higher than a mobile website. Number two, just to give you a couple of examples, one of the challenges of Airbnb compared to a hotel is you may type in a location and certain dates and maybe you're on vacation and you don't see exactly the home you need and you might not book a home. You might now open a different app. And we have this carousel that basically offers, hey, if you change your dates by one or two days, here are other listings you can find. And that led to a huge increase in booking. We made improvements to filters. We've made improvements to search input, the search box, making the search box more prominent. So there are quite literally dozens and dozens of improvements that we've made. And I see hundreds of basis points…

Thank you, Brian. Super helpful.

Your next question comes from the line of Eric Sheridan with Goldman Sachs. Please go ahead.

Thanks so much for taking the question. Maybe coming back and putting a finer point on some of the topics we've talked about already, Brian. When you think about your top investment priorities for 2024 and beyond, how would you categorize those investments if we put them in buckets such as demand generation, supply growth, and platform and product innovation over the long-term? And in that last bucket, how should we increasingly think about what you're learning about testing and deploying AI across the platform and how it might reduce friction over the longer term? Thanks so much.

Hey, Eric. Good to hear from you. So maybe I can just – you had three buckets. Maybe I can give you three slightly different buckets to give you our framework. The way I think about deploying our resources – and when I say resources, probably the most precious resources we have is product and engineering resources. And the way I think about that is we have our core business, we have international expansion, and we have expanding our core business of accommodation. So that's kind of the way we think about our portfolio. And you can imagine they're all totally different horizons. So the majority of our people are still focused on the core business. And I believe that we are just scratching the surface of the size of our core business. Within our core business, we typically have about three different areas of focus. One I just talked about, which is quality and reliability. The next one is affordability, making sure Airbnbs are more affordable hotels. And the third is usability, what I also talked about with search and reducing friction. So that's the first bucket of our investment. And that really will pay off within this year. And so there's – you can get a return on those efforts within a matter of months, because a lot of that – a lot of those changes are software changes. They're immediate. They touch 100% of our user base. And they touch a very large base, our entire GBV. Next is international expansion. International expansion is really supply, demand, and platform. It's all three within international. And you can really bucket into two things. We have to localize the product, and then we have to have a global marketing strategy to go one market at a time. And we've…

Great. Thank you.

And then I think the other question, sorry, I have to answer the question about how are you, what are we learning about AI and reducing friction? So just a couple of things in AI. First of all, like, we've been using AI for a long time. In the last 12 months, we've made a lot of progress. I'll just give you three examples of things we've done with AI. We've made it easier to host. We have a computer vision model that we trained in 100 million photos, and that allows hosts to, like the AI model, to organize all their photos by room. Why would you want to do this? Because this increases conversion rate when you do this. Number two, we launched last week AI-powered quick replies for hosts. So it basically predicts the right kind of question or answer for a host to pre-generate to provide to guests. And this has been really helpful. And then we've made a really big impact on reducing partisan Airbnb with our reservation screening technology. So now we're going much bigger on generative AI. I think we're going to see, I think we're going to see the biggest impact is going to be on, customer service in the near term. I think more than hotels, probably even more than OTA, Airbnb will benefit from generative AI. And the reason why is just a simple structural reason. We have the most, like, varied inventory. We don't have any SKUs. And we're an incredibly global platform. So it's a very difficult customer service challenge. But imagine an AI agent that can actually, like, read a corpus of a thousand pages of policies and be able to help adjudicate and help a customer service agent help a guest from Germany staying with a host in Japan. It's a very difficult problem and AI can really supplement. Over time, we're going to bring the AI capabilities from customer service to search and to the broader experience. And the end game is to provide basically an AI-powered concierge. So that's where it's going. But it's really focused on customer service at this very moment.

Your next question will come from the line of Brian Nowak with Morgan Stanley. Please go ahead.

Thanks for taking my questions. I have two just to sort of come back to a couple of the topics we talked about. The comp did get easier. So with the comps getting modestly harder in the back half, can you just sort of walk us through maybe micro levels of innovation that can sort of drive stability? Or how do we think about reasonable ranges of outcomes for room-night growth in the second half? And then the second one, you know, Brian, you talked about how like-for-like pricing is more attractive versus hotels. I don't have the transcript exactly yet. But if I look at Marriott and Hilton and their ADRs are up 2% to 3% and your ADRs are also up 2% to 3%, is there something else that you're seeing where the relative pricing is actually becoming more attractive that you can help us understand a little bit more? Thanks.

Yes. Why don't I take the second question? And I think, Brian, either you or I cut out. We didn't hear the first part of your question.

So do you want to just repeat the first question? Yes. Yes, absolutely. The first question was more for Ellie, where she has – you talked about how you have stable room-night growth now, but I think the comp is a little bit easier from 1Q to 2Q. And with the comps getting a little more difficult in the back half, can you just sort of walk us through some reasonable ranges of outcomes of growth in the back half and maybe micro-level drivers to kind of keep the stability versus drive deceleration?

Ellie, you want to take the first one, and I'll take the second one?

Yes. So I think you were right in terms of the thinking was that the comparison in Q2 would be a little bit softer. I think what we've seen so far, just to repeat what I said previously, is that, yes, it was clear that there was a hard comp in January. Since then, we've seen, I would just say, a general stability. We are not so far this year seeing the same level of volatility that we saw in 2023 in terms of either movement of lead times or consumer, I would say, hesitancy to book during kind of macro dislocation. So general statement is that, year-to-date, just the trends have been stable, and that's what our Q2 reflects. In terms of the back half of the year, I would say – I don't know if I would characterize the back half of the year as harder comps. I think if you recall, actually, some of the volatility that we and others saw in the back half of the year, there was a bit of a moment of dislocation end of summer heading into October, and in particular, in the month of October related to the conflict breaking out in Israel. So I wouldn't necessarily characterize the back half of the year as being a harder comp. Instead, I think if you think through the growth initiatives that Brian talked about in terms of thinking about where our portfolio of investments lie, I would say we are optimistic that a lot of the core optimizations could have near-term impact as well as the international investments. So those are the places where we're really looking to drive in-year growth above where we are today.

And Brian, I'll take the like-for-like question. So specifically, the data we're citing is global like-for-like basis. So what we're comparing is the average price of a global hotel room to a one-bedroom listing on Airbnb in March. And in March, our prices were down 2% and hotel prices were up 3%. So our prices were, again, one-bedroom globally on Airbnb in March was $114, down 2%. Hotels were $148, up 3%. So that's what we're talking about, one-bedroom global. When our ADRs move, obviously the other thing to take into consideration is mix shift. Oftentimes our ADRs do go up because people increasingly, more and more of our travel is group travel. 81% of our trips now have two or more guests and increasingly we're seeing people booking more space, larger homes, just as travel's mixing towards larger groups.

That's helpful. Thank you both.

And Brian, that was particularly the case in North America this quarter. On an absolute basis, ADRs were up, but if you exclude the impact of mix, they were flat.

Oh, okay. Great. Thank you both.

Your next question will come from the line of James Lee with Mizuho. Please go ahead.

Great. Thanks for taking my question. And just want to follow up the prior question on supply and demand growth. And in other segments of the gig economy services, they seem to benefit when supply exceeding demand. So if you think about, ride sharing and food delivery, because they drive prices down and therefore increasing consumer demand. Should we, think about it in the same path for home accommodation? Are you thinking, expecting maybe a similar trend for your business as well? Thanks.

I would say generally speaking, when we see growth in supply, it is additive to demand. It means that, when people are searching for a particular night in a particular city, if we have more that we can provide them, it is obviously net beneficial. I think I would just, repeat the prior comments that we don't always see kind of in period equivalence by market in terms of the respective growth rates. And that I would say that, there's a primary difference in terms of our business model relative to some of the others that you mentioned in that the frequency of the activity is simply lower and the lead time is also much longer.

Great, thank you.

Your next question comes from the line of Stephen Ju with UBS. Please go ahead.

Okay, thank you so much. So Brian, would we be overreaching if we were to think that Icons is a leading indicator of what should be, I guess, a revitalization or re-imagining of experiences? So, maybe the overnight stay in the [Indiscernible] generates all the media and consumer attention, but maybe this affords you the opportunity to expose the users you're getting to the more everyday experiences. And also secondarily, you've talked about this and the letter talks about this also, the Olympics and the Euro's bump, and there's going to be travelers who are probably not sports fans and who might want to be avoiding Paris and the host cities in Germany altogether. So, is there anything you can share in terms of how additive these two events may be? Thanks.

All right, Stephen. Well, that was, you are absolutely not overreaching on Icons. So let me give you a sense. You can think of a company as going through a few phases, especially to start a company. You have an idea, you get product market fit, that's phase one. Phase two is you try to go into hyper growth. We've done that. Phase three, you become a real company, you go public, you generate a return for shareholders. And then the fourth frontier, and very few companies have ever done this, is you reinvent yourself and you go from offering one thing to many things. And a lot of the big tech companies have done this. But one of the companies that I think is a really interesting one to look at is Nike. In the late 70s and early 80s, my recollection, I was born in 81, but my recollection is, I remember, Nike was mostly a running shoe company. And then the 80s, they became more popular with basketball and other things. But at the time, people didn't really think of Nike as a serious basketball shoe. And so they had to not only create a great product for basketball, but they had to actually stretch the brand and open up in people's minds what Nike stands for. And a lot of brands have had to do this. I mean Apple had to do this with the iPod. And I think Airbnb, one of the strengths of our brand also is something that we have to manage which is Airbnb is a noun and a verb. It's synonymous with a category, kind of like Kleenex or Xerox. People say, I'm going to get an Airbnb. I'm going to Airbnb my place. Literally, the name Airbnb has the name…

Yes, certainly. So if you look at our history, I would say that special events have always been kind of a good moment for Airbnb to shine and have been overall additive in terms of both our brand perception as well as supply growth. I think what we've seen from prior events, and I'm talking about pre-COVID Olympics, World Cup, Super Bowl, those type of events, what we see is that it should bring a ton of supply onto the platform. And while not all of that supply will persist, a good portion of it does. And so it's a nice supply acquisition moment for us. I would also say it's really additive in terms of signaling to cities how helpful and additive Airbnb can be to those cities to ramp up supply in a very organic and easy way without adding incremental hotel infrastructure that will not be necessarily needed long-term. And I think you see that in particular in Paris right now. We're going to be hugely additive in terms of hosting travelers for the games, whereas the existing infrastructure would not be able to manage such a large inflow.

Thank you.

Your next question will come from the line of Doug Anmuth with JPMorgan. Please go ahead.

Hey, this is Dave [ph] on for Doug. Thanks for taking the questions. One for you, Ellie. Can you talk about how you're thinking about the investment levers that provide flexibility and shape your 35% plus EBITDA margin guide for the full year? And can we expect to see these levers get pulled more through the year?

Yes, so I couldn't hear entirely, but a question about our guide for full year EBITDA margins, a floor of 35%. Let me just talk a little bit. Yes, the investment level.

Yes, and how you're thinking about investment levers.

Yes, of course. So let me just step back and provide a little bit more color in terms of why the 35%. If you look at our performance since the IPO, pre-IPO, we had a negative 5% EBITDA margin. And behold, three years after the IPO, we delivered nearly 37% EBITDA margins last year. I think we have repeatedly demonstrated the increased strength of this business model in terms of very strong profitability, inclusive of GAAP, net income profitability, as well as free cash flow. And at the same time, where we sit today, we see a huge opportunity in driving incremental growth. And so as we kicked off the year last quarter and looked at our opportunity set, we've identified a handful of areas where we'd like the flexibility to lean in and drive incremental growth beyond what we're seeing today. So where would you see those investment levers on the P&L? It's really two areas. So first, not surprisingly, is marketing. In marketing, we've been very disciplined over the last couple of years. We continue to have a much lower level of marketing intensity than really anyone else in travel. And at the same time, at the margin, we have seen some incremental opportunities to lean in on channels where we're seeing higher ROIs. In Q1, we saw nice, very high ROIs in performance marketing. To the extent that that continues, we would lean in modestly over the course of the year. Additionally, and probably more importantly, Brian talked a little bit about our opportunity set in international markets. And that's also an area where, to the extent that our full funnel marketing investments are working, we would look to top off those investments and to therefore accelerate growth. So marketing is one line item. You will potentially see some margin compression in order to drive growth. The second area, Brian talked about prioritizing our resources and identified that, in many cases, our product development team is our kind of scarcest resource. And I think when you hear us talk about our roadmap, you can obviously infer that we have a very robust list of initiatives that we would like to tackle. And so there's an opportunity to, at the margin, add more personnel over the course of the year to allow us to accelerate that roadmap. And you would see that in particular on the product development line item. So grand scheme of things, no material pivot in terms of our overall financial discipline, but instead a bit of lean into those areas where we believe we can accelerate growth.

Thank you for the detailed response.

Your next question will come from the line of Kevin Kopelman with TD Cowen. Please go ahead.

Great, thanks a lot. I had a question on the May release. You added a couple of small new features to the user profiles, I think on the photos and the travel stamps. Can we see that as a first step towards some of the profile enhancements and community features that you've talked about being interested in in the past and where does kind of building out potentially new community features stand in your priority list? Thanks.

Yes, hey Kevin. We spoke in this call mostly about Icons, but I mean, I am equally excited for the results that we've seen for group travel. I'm not going to go through all the metrics, but the metrics have been all really, really positive for group travel features. And in particular, one of the things we've seen is, when people book an Airbnb, the average number of guests is two. So that means that typically for every booking, there's another guest. But typically the other guest hasn't connected their account to Airbnb. So if you travel with a partner or a friend, maybe if you book, the other person doesn't actually have an account or they haven't connected their account. So as we've, and it's strategic for us to get more accounts, that would make sense, right? Especially as you want to sell more things beyond home. We want to have a point of sale for every single person on a trip, not just a point of sale for the booker. So this is really, really critical for us. And what we've seen is a major jump in the number of co-travelers that are now creating accounts in Airbnb and not only creating accounts, but filling out their profile. And so to answer your question, yes, this is the beginning of something much bigger. To probably zoom out, when we started Airbnb, there already were vacation rentals, but they were mostly on classified sites like Craigslist [ph] or there were like paid subscription services like Vrbo. And one of the innovations we brought is we added profiles, payments, two-sided reviews and messaging and those capabilities unlocked really this whole new category. This was what we may call the system of trust. So what we're now doing is we're going to be investing a lot more in increasing our profiles and our profile capabilities, both our account structure, cleaning it up, our identity verification, making, getting more people to complete more robust profiles, increasing their preferences so we have more information about people. And this is so strategic because as trust goes up, more, you can unlock more things for people. And as we know more about you, we can match you better. So, I think in the future, right now, if you think of like the Airbnb solar system, the home is like the sun at the center of the solar system. I think in the future, the profile will be at the center of the solar system of Airbnb and the home will be one of many categories orbiting the profile.

Great, thanks so much.

Your next question comes from the line of Nick Jones with Citizens JMP. Please go ahead.

Great, thanks for taking the questions. I guess maybe going back to supply and your effort to remove low quality supply. I guess, can you speak to the percentage of the supply that you've removed over time? I think you said 100 to 1,000 that I guess maybe take the removal and I guess the learnings and come back and try to list and provide a kind of a higher quality or better experience. I guess as you continue to remove lower quality supplies, it's becoming a tool to kind of nudge hosts into the behavior you're looking for without actually having to remove them.

Yes, I mean, hey Nick, why don't I take the first one? So, the first thing I'll say is the global occupancy on Airbnb is so much lower than hotels. So, even though you type in a certain date and a location, when it's a popular day and location, occupancy can rise at a global level. We are still like, not even close to high occupancy. And so, one of the games we need to do is we want to point them in to the best supply on Airbnb. So, we don't, and so having removed all this supply, we haven't seen a fundamental shift or impact on global bookings because a lot of them either weren't getting as many bookings in the first place, or they were eating up page views, they were lower converting listings, or people were booking them, they were really expensive because they were leading to customer service contacts, which were expensive. And if you went through all that, the revoking rate for them was much lower. Now, as far as the answer to your question about like how many of them come back, I don't have the stats on top of my head. But, I think that like this quality control program, one of the things we've noticed is that a lot of hosts are very coachable and learnable. They're very coachable and they can learn. So I think one of the problems in this category is historically there's these marketplaces have been so hands off that people don't know what it takes to be successful. And as you give them more like metrics, as you give them more incentive to be good, and as you create more boundaries about what's not acceptable in Airbnb, it actually does change behavior and people do come…

Thanks for the color, Brian.

Your next question will come from the line of Naved Khan with B. Riley Securities. Please go ahead.

Yes. Hi. Thanks a lot. Maybe a clarification from Ellie. I think, I heard you say you saw really good ROIs on the performance marketing channels. I wanted to understand better where that came from. And maybe on a related topic, was there any effect from either the rollout of the DMA in Europe in March, or maybe changes to Google search in late March and early April? And then I have a follow-up.

Yes. So, in terms of first, the higher ROIs that we're seeing on marketing, I would say we over the last year have just been frankly very encouraged with the ROIs that we've been able to deliver from that channel. In particular, like what has been driving that? Well, we've been continually testing, improving our performance marketing execution. We have expanded the target audiences. We've expanded our keyword coverage. We've made general improvements to the landing pages. And all of that has been, I would say, quite successful in terms of allowing us to spend marginally more and maintain really great efficiencies. So, really good channel for us, even though it is obviously a minority of our overall marketing spend or strategy. In terms of your second question, impact from the D&A rollout, I would say we haven't seen any meaningful impact. I think primarily that is because the majority, 90% of our traffic is coming to us through direct or unpaid traffic. And so, we have not seen any noticeable impact there yet or at all, I should say.

Okay. And then, yes, I know it does help. So, maybe just on the changes to the extenuating circumstances policy, I wanted to kind of understand better what kind of led to that change and what kind of impact we can expect from the outside looking in?

I didn't hear that question. Sorry.

Sorry, the changes to the extenuating circumstances policy, I think it was tweaked recently to kind of maybe raise the bar on the cancellation.

Extenuating circumstance policy. Brian, do you have any comments on that? I would say we just tried to clarify over time and make that more equitable for our guests and hosts, but no meaningful impact to the business.

Yes, I agree.

Your next question will come from the line of Conor Cunningham with Melius Research. Please go ahead.

Hi everyone. Thank you. Just on the under-penetrated international markets, as you develop those, I'm just curious if they're producing the, what you'd expect in terms of key KPIs from, take rate ADR profits, just trying to understand how the mixed changes are going to impact the overall company. And then just one on the 2Q to 3Q re-acceleration. I would assume that the booking window is a little bit more extended this year, given some of the events. Just curious on where you're booked into 3Q right now, just trying to understand the confidence interval there. Thank you.

Yes, sure. So first the question is around economics of our international expansion markets. So if you think about the various factors on our economics, so first there's virtually no change in terms of our underlying take rates by market. So that's not a factor. I would say second, depending on the market that we're targeting, many of these markets will have lower ADRs than our averages. So over time, to the extent that we were incrementally more successful in higher, seeing higher penetration in places like Latin America or Asia Pacific, we would anticipate that the global ADR would come down. And yet all of those nights would be accretive. So it would be market expanding, even if the nights were coming in at a lower ADR. And what we've been able to achieve over time is very strong economics at the booking level for a wide range of ADRs. So it is not a concern for us to be expanding in markets where the average ADRs are lower. It is again, just accretive in terms of the top line and the volume of the business. Your second question is around lead time. I would say generally speaking, as I said previously, our lead times year-to-date have been pretty flat on a year-over-year basis. We did not see a pull forward that maybe some others in the industry mentioned. And yet when we look forward in terms of the backlog for Q3, it's quite strong. And it's that backlog that gives us quite a bit of confidence around the comments we made in the outlook that Q3 revenue should accelerate above the Q2 outlook.

Appreciate it, thank you.

I will now turn the call back over to Brian Chesky for closing remarks.

All right, well, thank you all for joining us today. And I just wanted to say before I wrap up, this was Ellie's first earning call as CFO and the transition has gone incredibly well. Her, Dave and I are really, really focused on this next chapter of growth. So to recap, revenue was $2.1 billion, this is 18% higher than a year ago. Net income and adjusted EBITDA were both Q1 records and our trailing 12 month free cash flow was $4.2 billion, representing a free cash flow margin of 41%. Now we've made a tremendous amount of progress over the past few years. And with the launch of Icons, we're now laying the foundation for our plan to expand beyond our core business. This is just the beginning. Thank you all and we'll see you next quarter.

That concludes our call for today. We thank you all for joining and you may now disconnect.

For business. This is just the beginning. Thank you all and we'll see you next quarter.
