Sonder Investor Presentation Deck

Disclaimer 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 Free Cash Flow, Free Cash Flow Margin, Cash Contribution and Cash Contribution Margin. Further information about these measures appears under "Key Terms" to the right. Sonder's management uses these non-GAAP financial measures, collectively, to evaluate ongoing operations and for internal planning and forecasting purposes. Sonder believes that these non-GAAP financial measures are useful in evaluating its operating performance, and may assist investors in comparisons with other companies, some of which use similar non-GAAP financial information to supplement their GAAP results. However, Sonder's definitions 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 measures. 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. 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. Sonder has not reconciled consolidated Free Cash Flow guidance to projected consolidated GAAP cash provided by (used in) operating activities because Sonder does not provide guidance on GAAP cash provided by (used in) operating activities or the reconciling items between Free Cash Flow and GAAP cash provided by (used in) operating activities, as a result of the uncertainty regarding, and the potential variability of, certain of these items. Accordingly, a reconciliation of the non-GAAP financial measure guidance to the corresponding GAAP measure is not available without unreasonable effort. Sonder Key Terms Total Portfolio 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 exited (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. Certain signed leases have contingencies or conditions that must be satisfied before we take over the units, and from time to time, we exclude some of these leases from our Contracted Units total based on our judgment about the likelihood that the contingencies or conditions will be satisfied. Occupancy Rate Occupancy Rate is defined 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 represent the total number of nights occupied across all Live Units. Revenue per Available Room 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. Free Cash Flow Free Cash Flow ("FCF") is defined as cash provided by (used in) operating activities plus cash provided by (used in) investing activities, excluding the impact of restructuring charges, if any. Free Cash Flow Margin is defined as Free Cash Flow as a percentage of revenue. Reconciliation of Free Cash Flow to the most comparable GAAP measure can be found on pg 22. Cash Contribution Cash Contribution is defined as operating cash flow before non-property level expenses, excluding the impact of restructuring charges, if any. Cash Contribution Margin is defined as Cash Contribution as a percentage of revenue. Reconciliation of Cash Contribution to the most comparable GAAP measure can be found on pgs 23-24. 25
