Sonder Holdings Inc. Reports Record Revenue for Q2 and Raises FY 2021 Revenue Outlook

Record Q2 2021 Revenue of $47.3M, Up 151% YoY

$100 Revenue per Available Room, Up 112% YoY and 30% vs. Q1 2021

Raises Outlook for FY 2021 Total Revenue to $180M - $190M vs. Initial Outlook of $173M

San Francisco, CA – August 10, 2021 – Sonder Holdings Inc. (“Sonder” or the “Company”), a leading next-generation hospitality company that is redefining the guest experience through technology and design, today announced financial results for the three months ended June 30, 2021. Sonder delivered its strongest quarterly revenue in the Company’s history, driven by a robust recovery of leisure travel demand and the continued rapid expansion of its Live Unit portfolio.

“Q2 was an outstanding quarter for Sonder. We delivered our highest single quarter revenue in the Company’s history and more than doubled RevPAR year-over-year,” said Francis Davidson, Co-Founder and Chief Executive Officer of Sonder. “Our stellar results are a testament to our ability to attract and delight guests, as traveler preferences have evolved to seek out modern, tech-enabled spaces that fit a variety of needs and lifestyles. The inspired, tech-enabled design, consistent quality and compelling value that are hallmarks of the Sonder brand also position us to serve emerging travel trends such as long-term stays and digital nomadism.”

Davidson continued, “We continue to outperform traditional hotel RevPAR during the pandemic – by at least 40% in each of the past two quarters. Our Total Portfolio continues to expand rapidly and we’re on track to surpass 18,000 units by end of year, which gives us confidence in our ability to hit the aggressive growth targets we’ve set for 2022 and beyond.”

“Given the strong RevPAR outperformance through the first half of the year, and the rapid addition of new units to our portfolio, we are raising our outlook for 2021 Total Revenue,” said Sanjay Banker, President and Chief Financial Officer of Sonder. “This increase from our initial outlook reflects Sonder’s belief that the recent surge in leisure travel recovery is sustainable and our proven ability to capitalize on this demand for better stays at an exceptional value.”

The rebound in travel demand was underscored in a recent Sonder report, conducted in partnership with Ipsos, indicating that a majority of U.S. adults have plans for personal travel in the coming months. In the nationwide survey of U.S. adults 18 years or older, roughly two-thirds (62%) of survey respondents indicated they will travel for personal reasons before the end of 2021. Another six-in-ten (59%) Americans were interested in being a “digital nomad” – or working remotely on a long-term trip – with interest higher among younger adults aged 18-34 (74%), followed closely by those planning to travel with kids (69%).

Sonder’s Use of Non-GAAP Financial Measures

Sonder supplements its consolidated financial statements presented in accordance with generally accepted accounting principles in the United States (“GAAP”), by providing additional financial measures that are not prepared in accordance with GAAP, including Adjusted Gross Profit (Loss), Property Level Costs, Property Level Profit (Loss) and Adjusted EBITDA. Sonder believes that the disclosure of these non-GAAP financial measures provides investors with additional information that reflects the amounts and financial basis upon which Sonder’s management assesses and operates its business. Sonder’s definition may differ from the definitions used by other companies and therefore comparability may be limited. In addition, other companies may not publish these or similar metrics. These non-GAAP financial measures should not be viewed in isolation or as a substitute for, or superior to, measures prepared in accordance with GAAP.

Key Terms

Sonder’s Total Portfolio represents Live Units plus Contracted Units. This includes any unit that has a signed real estate contract, regardless of whether or not the unit is available for guests to book. This excludes any units that have been dropped (i.e., the lease was terminated or allowed to expire). Live Units are defined as units which are available for guest bookings on Sonder.com, the Sonder app and other channels. Sonder pays rent (or utilizes pre-negotiated abatement) and is able to generate revenue from these units. Contracted Units are units for which Sonder has signed real estate contracts, but are not yet available for guests to book. Sonder is not yet able to generate revenue from these units.

Sonder defines Occupancy Rate (“OR”) as Occupied Nights divided by Bookable Nights, expressed as a percentage. Bookable Nights represent the total number of nights available for stays across all Live Units. This excludes nights lost to full building closures of greater than 30 nights. Occupied Nights represents the total number of nights occupied across all Live Units.

Revenue Per Available Room (“RevPAR”) represents the average revenue earned per available night, and is calculated either by dividing revenue by Bookable Nights, or by multiplying Average Daily Rate by Occupancy Rate. Average Daily Rate (“ADR”) represents the average revenue earned per night occupied and is calculated as revenue divided by Occupied Nights.

Adjusted Gross Profit (Loss) represents GAAP gross profit (loss) impacted by the GAAP rent to Landlord Payment adjustment, expressed in U.S. dollars. GAAP gross profit (loss) is defined as revenue less cost of revenue (excluding depreciation and amortization). Landlord Payments represent Non-GAAP payments to real estate owners recognizing abatement at the time it is utilized (often at the commencement of a real estate contract), expressed in U.S. dollars. This recognizes the economic substance of the payment to real estate owners as reflected in the real estate contract.

Property Level Profit (Loss) (PLP or PLL) represents GAAP gross profit (loss) (i) impacted by the GAAP rent to Landlord Payment adjustment, and (ii) less Property Level Costs, expressed in U.S. dollars. Property Level Costs (PLC) represent variable costs directly associated with each of Sonder’s buildings, expressed in U.S. dollars. These costs include (i) channel fees paid to Online Travel Agencies (OTAs), (ii) customer service costs, (iii) laundry/consumables costs, (iv) maintenance costs, and (v) utilities & insurance costs.

Adjusted EBITDA represents GAAP profit (loss) from operations (i) impacted by the GAAP rent to Landlord Payment adjustment and (ii) excluding the impact of depreciation, stock-based compensation, COVID-19 pandemic related offboardings/other (costs associated with dropping units at the beginning of the COVID-19 pandemic), and cash payments from real estate owners received for capital expenditure financing, expressed in U.S. dollars.
