Q3 2021 Shareholder Letter

The travel rebound that began earlier this year accelerated in Q3, resulting in Airbnb’s strongest quarter ever. Revenue and net income were our highest ever. Adjusted EBITDA exceeded $1 billion, also our highest ever. This summer, we reached a major milestone of 1 billion cumulative guest arrivals as more people got vaccinated and travel restrictions were relaxed. Host earnings reached a record $12.8 billion in the quarter, and active listings continued to grow.

But something bigger than a travel rebound is happening. The world is undergoing a revolution in how we live and work. Technologies like Zoom make it possible to work from home. Airbnb makes it possible to work from any home. This newfound flexibility is bringing about a revolution in how we travel. Millions of people can now take more frequent trips, take longer trips, travel to more locations, and even live anywhere on Airbnb.

On May 24, we introduced the Airbnb 2021 Release, with over 100 upgrades to improve every aspect of the Airbnb service. We made it easier for anyone to become a Host, and added new features that gave guests more flexibility when planning their travel.

On November 9, we will be announcing the Airbnb 2021 Winter Release, with another 50+ upgrades and innovations that make it even easier to host and support the ongoing travel revolution. With this announcement, we’ll have delivered over 150 upgrades in 2021.

Live anywhere: A travel revolution

For centuries, people have been tethered to where they work. Then the pandemic hit and suddenly untethered tens of millions of people from the need to work in specific places at specific times. They can now work from anywhere, travel any time, and stay longer. For those who can work remotely, we believe that flexibility will be the most important benefit after compensation.

This newfound flexibility is blurring the lines between traveling and living. Technologies like Zoom make it possible to work from home. Airbnb makes it possible to work from any home. From long weekends to monthly stays, Airbnb allows you to book any home, anywhere, for any duration—and ultimately, to live anywhere.

This trend towards more flexibility will only accelerate. In recent months, some of the largest companies in the world, including Procter & Gamble, Ford Motor Company, PwC and Amazon, have announced increased flexibility for employees to work remotely, and we expect more companies to follow their lead.

Here are the business highlights that we are seeing as a result of this travel revolution:

November 9: Airbnb 2021 Winter Release

We’re constantly improving our service to meet this new way of traveling, and the wave of guests it will bring.

On May 24, we introduced the Airbnb 2021 Release, which included more than 100 upgrades across every aspect of the Airbnb service, from our website and app to our community support and policies.

On November 9, we will be announcing the Airbnb 2021 Winter Release, with another 50+ upgrades and innovations that make it easier to host and support the changing needs of travelers.

Progress on our 2021 Plan

Our single priority for 2021 has been to prepare for the travel rebound. To do this, we’ve been perfecting our existing product. We’ve made significant improvements to the end-to-end experience of our core service for both Hosts and guests, and we continue to focus on the following areas:

Educating the world about Airbnb

Earlier this year, we launched our first large-scale marketing campaign in five years, Made possible by Hosts. Through the campaign, we’re highlighting the unique experience of being hosted on Airbnb, as well as inspiring more people to become Hosts. In Q3, overall traffic to our platform increased over 15% in the seven countries where we ran the campaign compared to Q3 2019—significantly ahead of non-campaign countries. To continue the momentum of this campaign, we recently launched new ads for the fall season in the same countries.

6

Recruiting more Hosts

We have more Hosts as a result of our ongoing 2021 recruitment efforts. Hosts who started during the pandemic came from over 200 countries and regions, from Albania to Zimbabwe. Earlier this year, we launched a digital campaign focused on recruiting new Hosts, and in Q3 2021, traffic to our hosting landing page in campaign countries increased over 25% compared to Q3 2019.

We’ve also made it easier for new Hosts to get started in 10 simple steps. Throughout the listing process, new Hosts can also connect with Airbnb Superhosts for answers to their questions or concerns.

We began Ask a Superhost in nine countries, and have since expanded the program to over 30 languages in 196 countries. Prospective Hosts can now be paired with Superhosts based on their location, language and listing. To date, more than 60,000 prospective Hosts have used Ask a Superhost. We are excited to scale this program going forward.

Simplifying the guest journey

Earlier this year, we introduced I’m Flexible, a whole new way to search on Airbnb when guests are flexible about where or when they are traveling. Since then, guests have used I’m Flexible more than 500 million times. Due to the popularity of this feature, on November 9, we’re making it even more flexible by expanding the date range to 12 months out (from six). For those who like to plan trips by type of stay, we’re also expanding I’m Flexible to include four new categories of unique stays, from off the grid to ski-in/ski-out.

Delivering world-class service

We’re committed to providing world-class support for our global community. In September, we launched dedicated Superhost support, giving our most experienced Hosts priority access to our most experienced support agents. We’ve rolled this out in North America and plan to expand the service to all Superhosts globally by the end of the year.

In Q3, we announced the expansion of our Neighborhood Support Line to even more countries (now live in a total of 29 countries and regions), giving access to more community members to raise urgent concerns about a nearby listing directly with Airbnb. Around the world, the rollout of the Neighborhood Support

10

Line has proven to be an important tool in Airbnb’s efforts to combat unauthorized gatherings and enforce our global ban on parties.

Housing 20,000 Afghan refugees

To help support the resettlement of Afghans here in the U.S. and elsewhere, in August, Airbnb.org committed to providing temporary housing to 20,000 Afghan refugees worldwide. None of this would be possible without Airbnb Hosts and Airbnb.org’s non-profit resettlement partner organizations. To date, more than 6,400 Hosts have offered free or discounted stays, and over 3,000 Afghan refugees have been housed.

Q3 2021 Business and Financial Performance

Q3 2021

In Q3 2021, Nights and Experiences Booked of 79.7 million represented a significant increase from a year ago (+29% Y/Y) and slight decrease compared to Q3 2019 levels (-7% Y/2Y). Excluding Asia Pacific, global Nights and Experiences Booked exceeded 2019 levels in the quarter. Continued strength in ADR drove even stronger GBV performance than Nights and Experiences Booked. In Q3 2021, GBV was $11.9 billion, representing a year-over-year increase of 48% (or 46% ex-FX) and an increase of 23% compared to Q3 2019.

Geographic mix

The trends in our recovery continue to vary by region due to vaccination rates, COVID caseloads and associated travel restrictions, as well as pre-COVID travel patterns. In Q3 2021, we saw continued strength in North America and EMEA and an acceleration in Latin America relative to Q2. Meanwhile, global cancellations remained higher than 2019 levels. Here are some regional highlights:

Travel corridors and distance

We are seeing recovery in both longer-distance and cross-border travel this year, while domestic and short-distance travel continue to be more popular than 2019 levels. Cross-border travel jumped to 33% of gross nights booked in Q3, up from 27% in Q2 and only 20% in Q1. As more countries continue to reduce travel restrictions (including the U.S. reopening to fully vaccinated travelers beginning on November 8), we expect the continued recovery of cross-border travel to be a tailwind to future quarterly results. In fact, in October we saw meaningful incremental recovery of cross-border gross nights booked, which are now approximately 80% of 2019 levels.

Urban vs. non-urban

As seen in prior quarters, growth for gross nights booked was strongest in non-urban areas during the quarter compared to Q3 2019. While travel to top cities has not yet recovered to 2019 levels, we are seeing signs of travelers returning to cities (historically one of the strongest areas of our business). Travel to high-density urban areas increased in Q3 from the prior quarter. High-density urban areas represented 46% of our gross nights booked in Q3 2021 compared to just over 40% in Q2 2021. Searches for stays in high-density urban areas have also grown each quarter, and were over 60% higher in Q3 2021 compared to Q1 2021.

Trip length

In Q3 2021, long-term stays of 28 days or more remained our fastest-growing category by trip length compared to 2019 as the way people travel and live continues to change. Long-term stays accounted for 20% of gross nights booked in Q3 2021, up from 14% in Q3 2019. Overall, 45% of gross nights booked were from stays of at least seven nights in Q3 2021.

Average daily rates

ADR averaged approximately $149 in Q3 2021, representing a 15% increase compared to the same prior year period, and a 33% increase compared to the same period in 2019. The drivers of ADR appreciation in Q3 remained primarily mix shift and price appreciation. We continued to see significant mix shift towards bookings in North America, entire homes, and non-urban destinations, all of which tend to have higher ADR. Mix shift has been the primary driver of ADR increases throughout the year. In Q3, we saw a growing impact from price appreciation driven by high-demand locations.

Supply

Beginning in early 2021, we launched our Made possible by Hosts campaign to educate people on the benefits of hosting. On May 24, we announced more than 100 upgrades to refine and improve every aspect of the Airbnb service. These initiatives have helped drive supply growth. The number of active listings has grown every quarter this year and growth was again strongest in non-urban areas—areas where guest demand was highest. Consistent with where we’ve seen bookings recover, we’ve seen the most growth in active listings in Latin America with 25% in Q3 2021 compared to Q3 2019, followed by North America with 10% and EMEA with 9%. And, once new Hosts list, they are getting their first booking faster.

Q3 2021

In Q3 2021, revenue was $2.2 billion, our strongest ever, representing a year-over-year increase of 67% (or 64% ex-FX). The increase in revenue was driven by the recovery in Nights and Experiences Booked, combined with a higher ADR compared to Q3 2020. Compared to Q3 2019, revenue in Q3 2021 increased 36%, driven by higher ADR offsetting slightly lower nights stayed.

Net income in Q3 2021 was $834 million, our strongest ever, compared with $219 million in Q3 2020. Net income was primarily driven by substantially higher revenue in Q3 2021. Our net income in Q3 2020 included restructuring charges, interest expense on debt that has subsequently been extinguished, as well as adjustments to the carrying value of certain warrants and investments. In Q3 2019, net income was $267 million. The improvement in net income compared to 2019 was primarily due to higher revenue and our significantly better cost structure as discussed further below.

Adjusted EBITDA for Q3 2021 was $1.1 billion, our strongest ever, which was substantially improved compared to Adjusted EBITDA in Q3 2020 of $501 million.³ This improvement was primarily due to the significant revenue recovery from a year ago. Relative to Q3 2019, Adjusted EBITDA margins increased 30% (from 19% Adjusted EBITDA margin in Q3 2019 to 49% Adjusted EBITDA margin in Q3 2021), even higher than the 20% margin expansion we saw in Q2 2021. This substantial improvement in Adjusted EBITDA demonstrates the strength of our revenue recovery, the benefit of strong ADRs, as well as our significantly improved cost structure, including: reduced variable costs, lower marketing expense and fixed cost management.

As a reminder, seasonal trends impact our business. Q3 is typically our largest quarter due to the summer travel peak, impacting our revenue and Adjusted EBITDA and Q4 is typically a smaller quarter in terms of both bookings and check-ins, and therefore revenue and Adjusted EBITDA.

Quarterly Revenue ($M)

Q3 2021 revenue was our highest ever as guests travel and live on Airbnb.

Quarterly Net Income ($M)

Q3 2021 was our most profitable quarter yet, with net income increasing 280% from the same prior year period.

Quarterly Adjusted EBITDA ($M)

Q3 Adjusted EBITDA of $1.1B was our strongest ever, despite the continued impact of COVID-19.

15

Operating expenses in Q3 2021 included the impact of $211 million of stock-based compensation expense, which is excluded from Adjusted EBITDA. All operating expense line-items (excluding the impact of stock-based compensation expense), with the exception of sales and marketing, increased more slowly year-over-year than revenue, allowing for considerable margin expansion: ⁴

For the nine months ended September 30, 2019 and 2021, we had revenue of $3.7 billion and $4.5 billion, respectively, and net loss of $323 million and $407 million, respectively. For both the nine months ended September 30, 2019 and 2021, net loss margin was 9%.

For the nine months ended September 30, 2021, we delivered 28% Adjusted EBITDA margin expansion relative to the same period in 2019 (from roughly break-even for the nine months ended September 30, 2019 to 28% for the same period in 2021). We estimate that approximately two thirds of that margin expansion has been driven by our financial discipline and optimized marketing strategy, and the remaining one third driven by favorable unit economics related to our significantly higher ADRs.

Balance Sheet and Cash Flows

In Q3 2021, we reported $523 million of net cash provided by operating activities and $518 million of Free Cash Flow.⁵ For the nine months ended September 30, 2021, we had $1.8 billion of both net cash provided by operating activities and Free Cash Flow, both record highs.⁶ Seasonal trends in our GBV

^{4, 5, 6} A reconciliation of non-GAAP financial measures to the most comparable GAAP measures is provided at the end of this letter.

16

impact Free Cash Flow for any given quarter. We typically see a slight decline in GBV and a peak in check-ins in the third quarter, which results in a decrease in unearned fees and lower sequential level of Free Cash Flow.

As of September 30, 2021, we had $7.9 billion of cash, cash equivalents, marketable securities, and restricted cash. We also had $3.9 billion of funds held on behalf of guests at the end of Q3 2021.

Unearned fees totaled $892 million at the end of Q3 2021, compared to $1.5 billion at the end of Q2 2021 and $408 million at the end of Q4 2020. The sequential decrease in Q3 reflects seasonality which results in greater check-ins for bookings received in earlier periods and lower GBV.

Outlook

We are incredibly proud of our best quarter on record. Our Q3 2021 results illustrate that travel continues to recover from COVID-19, but is coming back differently, and that Airbnb is uniquely positioned for this travel revolution. We are encouraged to see these new travel trends extending beyond summer travel peak, and are looking forward to a strong Q4 with accelerating GBV growth, continued revenue strength, and further Adjusted EBITDA margin expansion, compared to Q3 2021, as described below.

As of the end of September, our backlog had over 40% more nights booked for Thanksgiving week in the U.S. than at the same time in 2019. And we are seeing the strong demand for travel extend well into 2022.

Nights and Experiences Booked and GBV

In Q4, we continue to see the positive effect of travel restrictions being lifted and global vaccination progress on our growth in Nights and Experiences Booked for stays in Q4 and into 2022.

We expect Nights and Experiences Booked in Q4 2021 to significantly outperform Q4 2020 levels and approximate Q4 2019 levels. In Q3 2021, our ADR declined from Q2 2021 due to the recovery of lower ADR regions, but we expect our ADR will be relatively stable in Q4 2021 relative to Q3 2021. Consequently, we expect Q4 2021 GBV to be substantially above both Q4 2020 and Q4 2019 levels, and Q4 2021 GBV year-over-two-year growth to accelerate from Q3 2021.

Looking to 2022, vaccination progress and the recovery of international travel in Q4 2021 will be key themes for growth heading into the new year. We continue to expect ADR to moderate over time based on the recovery of lower ADR regions and return to urban destinations.

Revenue and EBITDA

We expect to deliver Q4 revenue of between $1.39 billion and $1.48 billion, representing strong growth relative to both Q4 2020 and Q4 2019. Q4 revenue—in both absolute dollars and as a percentage of GBV—will decrease from Q3 due to travel seasonality.

We remain focused on making progress towards achieving our long-term profitability goals through reduced variable costs, high marketing efficiency and tightly managed fixed expenses. We expect our Q4 Adjusted EBITDA to show this continued progress, adjusted for seasonality. Specifically, we expect to deliver greater year-over-year and year-over-two year margin expansion in Q4 2021 than we delivered in Q3 2021.

Non-GAAP Financial Measures

In addition to our results determined in accordance with generally accepted accounting principles in the United States (“GAAP”), we review financial measures that are not calculated and presented in accordance with GAAP (“non-GAAP financial measures”). We believe our non-GAAP financial measures are useful in evaluating our operating performance. We use the following non-GAAP financial information, collectively, to evaluate our ongoing operations and for internal planning and forecasting purposes. We believe that non-GAAP financial information, when taken collectively, may be helpful to investors because it provides consistency and comparability with past financial performance, and assists in comparisons with other companies, some of which use similar non-GAAP financial information to supplement their GAAP results. The non-GAAP financial information is presented for supplemental informational purposes only, should not be considered a substitute for financial information presented in accordance with GAAP, and may be different from similarly titled non-GAAP measures used by other companies. A reconciliation of each non-GAAP financial measure to the most directly comparable financial measure stated in accordance

19

with GAAP is provided below. Investors are encouraged to review the related GAAP financial measures and the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measures.

Our non-GAAP financial measures include Adjusted EBITDA, Adjusted EBITDA Margin, Free Cash Flow and trailing twelve months (“TTM”) Free Cash Flow.

Adjusted EBITDA is defined as net income or loss adjusted for (i) provision for (benefit from) income taxes; (ii) interest income, interest expense, and other income (expense), net; (iii) depreciation and amortization; (iv) stock-based compensation expense and stock-settlement obligations related to the IPO; (v) acquisition-related impacts consisting of gains (losses) recognized on changes in the fair value of contingent consideration arrangements; (vi) net changes to the reserves for lodging taxes for which management believes it is probable that we may be held jointly liable with Hosts for collecting and remitting such taxes; and (vii) restructuring charges.

The above items are excluded from our Adjusted EBITDA measure because these items are non-cash in nature, or because the amount and timing of these items is unpredictable, not driven by core results of operations and renders comparisons with prior periods and competitors less meaningful. Reconciliations of expected Adjusted EBITDA and Adjusted EBITDA margins to corresponding net income (loss) and net income (loss) margins have not been provided because of the unpredictability of certain of the items excluded from Adjusted EBITDA and because we cannot determine their probable significance. We believe Adjusted EBITDA provides useful information to investors and others in understanding and evaluating our results of operations, as well as provides a useful measure for period-to-period comparisons of our business performance. Moreover, we have included Adjusted EBITDA in this letter because it is a key measurement used by our management internally to make operating decisions, including those related to operating expenses, evaluating performance, and performing strategic planning and annual budgeting. Adjusted EBITDA also excludes certain items related to transactional tax matters, for which management believes it is probable that we may be held jointly liable with Hosts in certain jurisdictions.

Adjusted EBITDA has limitations as a financial measure, should be considered as supplemental in nature, and is not meant as a substitute for the related financial information prepared in accordance with GAAP. These limitations include the following:

20

Adjusted EBITDA Margin is defined as Adjusted EBITDA divided by revenue. Because of these limitations, you should consider Adjusted EBITDA and Adjusted EBITDA Margin alongside other financial performance measures, including net income (loss) and our other GAAP results.

Free Cash Flow represents net cash provided by (used in) operating activities less purchases of property and equipment. We believe that Free Cash Flow is a meaningful indicator of liquidity that provides information to management and investors about the amount of cash generated from operations that, after purchases of property and equipment, can be used for strategic initiatives, including continuous investment in our business, growth through acquisitions, and strengthening our balance sheet. Our Free Cash Flow is impacted by the timing of GBV because we collect our service fees at the time of booking, which is generally before a stay or experience occurs. Funds held on behalf of our Hosts and guests and amounts payable to our Hosts and guests do not impact Free Cash Flow, except interest earned on these funds. We track our TTM Free Cash Flow to account for the timing difference in when we receive cash from service fees, which is at the time of booking. Free Cash Flow has limitations as an analytical tool and should not be considered in isolation or as a substitute for analysis of other GAAP financial measures, such as net cash provided by (used in) operating activities. Free Cash Flow does not reflect our ability to meet future contractual commitments and may be calculated differently by other companies in our industry, limiting its usefulness as a comparative measure.
