Key Metrics and Non-GAAP Financial Measures

Members: Members include both Consumer and Enterprise members as well as At-Risk members as defined below. Our number of members depends, in part, on our ability to successfully market our services directly to consumers including Medicare-eligible as well as non-Medicare eligible individuals, to Medicare Advantage health plans and Medicare Advantage enrollees, to employers that are not yet enterprise clients, as well as our activation rate within existing enterprise clients. We define estimated activation rate for any enterprise client at a given time as the percentage of eligible lives enrolled as members. While growth in the number of members is an important indicator of expected revenue growth, it also informs our management of the areas of our business that will require further investment to support expected future member growth. Member numbers as of the end of each period are rounded to the thousands.

Consumer and Enterprise Members: A Consumer and Enterprise member is a person who has registered with us and has paid for membership for a period of at least one year or whose membership has been sponsored by an enterprise or other third party under an agreement having a term of at least one year. Consumer and Enterprise members do not include trial memberships, our virtual only One Medical Now users, or any temporary users. Our number of Consumer and Enterprise members depends, in part, on our ability to successfully market our services directly to consumers and to employers that are not yet enterprise clients and our activation rate within existing clients. Consumer and Enterprise members may include individuals who are: (i) Medicare-eligible and (ii) have paid for a membership or whose membership has been sponsored by an enterprise or other third party. Consumer and Enterprise members do not include any At-Risk members as defined below. Consumer and Enterprise members help drive commercial revenue.

At-Risk Members: An At-Risk member is a person for whom we are responsible for managing a range of healthcare services and associated costs. At-Risk members help drive Medicare revenue.

Reconciliations of non-GAAP financial measures to the most directly comparable financial results as determined in accordance with GAAP are included at the end of this press release following the accompanying financial data. We believe that these non-GAAP financial measures, when taken together with the corresponding GAAP financial measures, provide meaningful supplemental information regarding our performance by excluding certain items that may not be indicative of our business, results of operations, or outlook. However, non-GAAP financial information is presented for supplemental informational purposes only, has limitations as an analytical tool and should not be considered in isolation or as a substitute for financial information presented in accordance with GAAP. In addition, other companies, including companies in our industry, may calculate similarly-titled non-GAAP measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of our non-GAAP financial measures as tools for comparison.

Medical Claims Expense Ratio: We define Medical Claims Expense Ratio as medical claims expense divided by Capitated Revenue. The nature of our contracting with Medicare Advantage payers and CMS requires us to be financially responsible for a range of healthcare services of our At-Risk members. Our care model focuses on leveraging the primary care setting as a means of reducing unnecessary or avoidable health care costs and balancing our cost of care with the impact of our service levels on medical claims expense. We are liable for potentially large medical claims should we not effectively manage our At-Risk members’ health. We therefore consider the Medical Claims Expense Ratio to be an important measure to monitor our performance. As we sign up new At-Risk members or open new offices to serve these members, our Medical Claims Expense Ratio is likely to increase initially due to a potential increase in medical claims expense from a lag in improvement in health outcomes with member tenure. Similarly, there may be a lag in adequately documenting the health status of our members, resulting in different Capitated Revenue compared to what is indicated by the health status of an At-Risk member. We believe that the Medical Claims Expense Ratio for a given set of At-Risk members can improve over time as we help improve their health outcomes relative to their underlying health conditions.

Care Margin: We define Care Margin as income or loss from operations excluding depreciation and amortization, general and administrative expense and sales and marketing expense. We consider Care Margin to be an important measure to monitor our performance, specific to the direct costs of delivering care. We believe this margin is useful to both us and investors to measure whether we are effectively pricing our services and managing the health care and associated costs, including medical claims expense and cost of care, of our At-Risk members successfully. We have provided below a reconciliation of historical Care Margin to loss from operations, its most directly comparable GAAP financial measure.

Adjusted EBITDA: We define Adjusted EBITDA as net income or loss excluding interest income, interest and other income (expense), depreciation and amortization, stock-based compensation, provision for (benefit from) income taxes, certain legal or advisory costs, and acquisition and integration costs that we do not consider to be expenses incurred in the normal operation of the business. Such legal or advisory costs may include but are not limited to expenses with respect to evaluating potential business combinations, legal investigations, or settlements. Acquisition and integration costs include expenses incurred in connection with the closing and integration of acquisitions, which may vary significantly and are unique to each acquisition. We started to exclude prospectively from our presentation certain legal or advisory costs from the first quarter of 2021 and acquisition and integration costs from the second quarter of 2021, because amounts incurred in the prior periods were insignificant relative to our consolidated operations. We include Adjusted EBITDA because it is an important measure upon which our management assesses and believes investors should assess our operating performance. We consider Adjusted EBITDA to be an important measure to both management and investors because it helps illustrate underlying trends in our business and our historical operating performance on a more consistent basis. We have provided below a reconciliation of historical Adjusted EBITDA to net loss, its most directly comparable GAAP financial measure.
