Annualized, pro forma, projected and estimated numbers are used for illustrative purpose only, are not forecasts and may not reflect actual results. Note: Francis Davidson, Sonder's Founder and CEO, plans to sell a small portion of his shares to a PIPE investor in a private transaction wholly separate from the transactions contemplated hereby, the proceeds of which will be used to repay a portion of an outstanding loan issued by Sonder for the purpose of early exercise of stock options.

Any estimates or projections contained herein involve elements of subjective judgment and analysis that may or may not prove to be accurate. None of Sonder, GM II, their respective affiliates or any third parties that provide information to Sonder, GM II or their respective affiliates, such as market research firms, guarantee the accuracy, completeness, timeliness or availability of any information or are responsible for any errors or omissions (negligent or otherwise), regardless of the cause, or the results obtained from the use of such content.

None of Sonder, GM II or their respective affiliates give any express or implied warranties, including, but not limited to, any warranties of merchantability or fitness for a particular purpose or use, and they expressly disclaim any responsibility or liability for direct, indirect, incidental, exemplary, compensatory, punitive, special or consequential damages, costs, expenses, legal fees or losses (including lost income or profits and opportunity costs) in connection with the use of the information herein. None of Sonder, GM II, their respective affiliates or any of their respective directors, officers, employees, members, partners, stockholders, or agents makes any representation or warranty with respect to the accuracy of such information. Non-GAAP Financial Measures This Presentation includes certain non-GAAP financial measures that Sonder's management uses to evaluate Sonder's operations, measure its performance and make strategic decisions. The non-GAAP financial measures used in this Presentation are Property Level Costs (PLC), Property Level Profit (Loss) (PLL or PLP) and Adjusted EBITDA. All references to Property Level Profit (Loss) (PLP or PLL) and Adjusted EBITDA in this document are based on our revised methodology as of September 2021. Property Level Profit (Loss) (PLP or PLL) and Adjusted EBITDA methodologies prior to September 2021 utilized Non-GAAP rent (which accounted for the benefit of rent abatement in the period in which it was received). Additionally, Adjusted EBITDA prior to September 2021 included the benefit of Capex Allowance in Non-GAAP Other Operating Expenses in the period in which it was received. Property Level Profit (Loss) (PLP or PLL) and Adjusted EBITDA now utilize GAAP rent, which amortizes the benefit of both rent abatement and benefit of Capex Allowance over the term of the lease. Property Level Profit (Loss) (PLP or PLL) is now defined as loss from operations after adding back corporate-level expenses less Property Level Costs. Property Level Costs (PLC) are costs directly associated with guest-facing functions in each of Sonder's buildings. These costs include (1) 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 is now defined as net loss excluding the impact of depreciation, stock-based compensation, and COVID-19 pandemic related offboardings/other (costs associated with dropping units at the beginning of the COVID-19 pandemic). 2#3Disclaimer Sonder and GM II believe that such non-GAAP financial measures provide useful information to investors and others in understanding and evaluating Sonder's operating results in the same manner as Sonder management. However, such financial measures are not calculated in accordance with GAAP and should not be considered as a substitute for revenue, net income, operating profit, or any other operating performance measure calculated in accordance with GAAP. Using any such financial measure to analyze Sonder's business would have material limitations because the calculations are based on the subjective determination of management regarding the nature and classification of events and circumstances that investors may find significant. In addition, although other companies in Sonder's industry may report measures titled EBITDA or similar measures, such financial measures may be calculated differently from how Sonder calculates such financial measures, which reduces their overall usefulness as comparative measures. Because of these limitations, you should consider these non-GAAP financial measures alongside other financial performance measures, including net income and other financial results, presented in accordance with GAAP. Key Metrics This Presentation includes certain non-GAAP financial measures and key metrics that Sonder's management uses to evaluate Sonder's operations, measure its performance and make strategic decisions. The key metrics used in this Presentation are Live Units, Bookable Nights, Average Daily Rate and RevPAR. 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. Bookable Nights represent the total number of nights available for stays across all Live Units excluding nights lost to full building closures greater than 30 nights, in line with industry standards. Sonder previously calculated Bookable Nights excluding unit closures, regardless of length of closure or number of units. Sonder's change in methodology in the calculation of Bookable Nights increased historical and forecasted Bookable Nights, decreased historical and forecasted RevPAR, and had no effect on the historical or forecasted financial information. Average Daily Rate represents the average revenue earned per night occupied, and is calculated as Revenue divided by the total number of Occupied Nights across all Live Units. 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, expressed in U.S. dollars. Trademarks and Trade Names Sonder and GM II and their respective affiliates own or have rights to various trademarks, service marks and trade names that they use in connection with the operation of their respective businesses.

Property Level Profit (Loss) (PLP or PLL) now utilizes GAAP rent, which amortizes the benefit of both rent abatement and benefit of Capex Allowance over the term of the lease. Property Level Profit (Loss) (PLP or PLL) is now defined as loss from operations after adding back corporate-level expenses less Property Level Costs. Property Level Costs (PLC) are costs directly associated with guest-facing functions in each of Sonder's buildings.
