The revenue and adjusted EBITDA outlook provided above is based on revenue and results recognized under the new accounting guidance under ASC 606, Revenue from Contracts with Customers (“ASC 606”). Please refer to the tables attached to this press release for a reconciliation of ASC 605, Revenue Recognition (“ASC 605”), to ASC 606 for our 2019 financial result.

Additional information on Livongo's reported results, including a reconciliation of the non-GAAP results to their most comparable GAAP measures, is included in the financial tables below.

The forward-looking Adjusted EBITDA contained in the section titled "First Quarter and Fiscal 2020 Outlook" excludes (i) depreciation and amortization, (ii) amortization of intangible assets, (iii) stock-based compensation expense, (iv) acquisition-related expenses, (v) change in fair value of contingent consideration, (vi) other income, net, and (vii) provision for (benefit from) income taxes. We have not reconciled adjusted EBITDA guidance to GAAP net income (loss) because we do not provide guidance on GAAP net income (loss) or the reconciling items between adjusted EBITDA and GAAP net income (loss) as a result of the uncertainty regarding, and the potential variability of, certain of these items, the effect of which may be significant. Accordingly, a reconciliation of the non-GAAP financial measure guidance to the corresponding GAAP measure is not available without unreasonable effort.

Non-GAAP Financial Measures

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. We compensate for these limitations by analyzing current and future results on a GAAP basis as well as a non-GAAP basis and by providing specific information regarding the GAAP items excluded from these non-GAAP financial measures. For a description of these non-GAAP financial measures, including the reasons management uses each measure, please see the section of the tables titled "About Non-GAAP Financial Measures."

ASC 606 Adoption Impact on Results of Operations

We adopted ASC 606 for the year ended December 31, 2019 using the modified retrospective method to customer contracts that were not completed as of January 1, 2019. Results of operations for the interim periods during 2019 have been adjusted to reflect the adoption of ASC 606. ASC 606 impact on revenue was immaterial; sales and marketing expense increased due to the difference in the timing of the recognition of incremental costs to obtain client contracts. Prior year results of operations are not affected by the adoption of ASC 606. The adoption of ASC 606 does not impact our net operating cash flows, investing cash flows, or financing cash flows.

The following table presents the ASC 606 impact on our results of operations:

About Non-GAAP Financial Measures

In addition to our financial results determined in accordance with GAAP, we believe non-GAAP measures are useful in evaluating our operating performance. In particular, we believe that the use of adjusted gross profit, adjusted gross margin, non-GAAP net loss and adjusted EBITDA is helpful to our investors as they are metrics used by management in assessing the health of our business and our operating performance. We use these non-GAAP financial measures to evaluate our ongoing operations and for internal planning and forecasting purposes. A reconciliation is provided below for each non-GAAP financial measure to the most directly comparable financial measure stated 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, and not to rely on any single financial measure to evaluate our business.

Non-GAAP Net Loss

We define non-GAAP net loss as net loss less (i) stock-based compensation expense, (ii) amortization of intangible assets, (iii) acquisition related expenses, (iv) secondary offering costs, (v) secondary offering related payroll taxes, (vi) change in fair value of contingent consideration, and (vii) tax impact. Non-GAAP net loss is used by our management to understand and evaluate our operating performance and trends. We believe that non-GAAP net loss is helpful in providing useful information about our operating results because it eliminates the effect of items that are unrelated to overall performance, but non-GAAP net loss is not meant to be considered in isolation or as a substitute for comparable GAAP measures and should be read only in conjunction with our consolidated financial statements prepared in accordance with GAAP.

We adopted ASC 606 for year ended December 31, 2019 using the modified retrospective method. Interim periods for 2019 have been adjusted to reflect the adoption of ASC 606. Impact of the ASC 606 adoption on non-GAAP results may vary from our GAAP results due to the capitalization and amortization of stock-based compensation expenses related to incremental costs of obtaining contracts with clients. Results of operations for the prior year periods are not affected by the adoption of ASC 606. Reconciliation of non-GAAP results from the most comparable GAAP measures are provided below.

Adjusted Gross Profit and Adjusted Gross Margin

Adjusted gross profit and adjusted gross margin are key performance measures that our management uses to assess our overall performance. We define adjusted gross profit as GAAP gross profit, excluding stock-based compensation expense and amortization of intangible assets. We define adjusted gross margin as our adjusted gross profit divided by our revenue. We believe adjusted gross profit and adjusted gross margin provide our management and investors consistency and comparability with our past financial performance and facilitate period-to-period comparisons of operations, as these metrics eliminate the effects of stock-based compensation and amortization of intangible assets from period-to-period as factors unrelated to overall operating performance.

We adopted ASC 606 for year ended December 31, 2019 using the modified retrospective method. Interim periods for 2019 have been adjusted to reflect the adoption of ASC 606. Results of operations for the prior year are not affected by the adoption of ASC 606.

The following table presents a reconciliation of adjusted gross profit from the most comparable GAAP measure, gross profit:

Adjusted EBITDA

Adjusted EBITDA is a key performance measure that our management uses to assess our operating performance. Because adjusted EBITDA facilitates internal comparisons of our historical operating performance on a more consistent basis, we use this measure for business planning purposes and in evaluating acquisition opportunities.

We calculate adjusted EBITDA as net loss adjusted to exclude (i) depreciation and amortization, (ii) amortization of intangible assets, (iii) stock-based compensation expense, (iv) acquisition-related expenses, (v) secondary offering costs, (vi) secondary offering related payroll taxes, (vii) change in fair value of contingent consideration, (viii) other income, net, and (ix) provision for (benefit from) income taxes.

We adopted ASC 606 for year ended December 31, 2019 using the modified retrospective method. Interim periods for 2019 have been adjusted to reflect the adoption of ASC 606. Impact of the ASC 606 adoption on non-GAAP adjusted EBITDA results may vary from our GAAP results due to the capitalization and amortization of stock-based compensation expenses related to incremental costs of obtaining contracts with clients. Results of operations for the prior year are not affected by the adoption of ASC 606.

The following table presents a reconciliation of adjusted EBITDA from the most comparable GAAP measure, net loss:

______________

(1) Depreciation and amortization includes depreciation of property and equipment and amortization of capitalized internal-use software costs.
(2) Acquisition-related expenses consist primarily of transaction and transition related fees and expenses, including legal, accounting, and other professional fees.
(3) Secondary offering costs consist of transaction related fees and expenses, including legal, accounting, and other professional fees associated with our secondary offering completed in December 2019.
(4) Secondary offering related payroll taxes consist of payroll tax expenses associated with equity awards released.
(5) Other income, net includes interest income, interest expense, and other income (expense).

Some of the limitations of adjusted EBITDA include (i) adjusted EBITDA does not properly reflect capital commitments to be paid in the future, and (ii) although depreciation and amortization are non-cash charges, the underlying assets may need to be replaced and adjusted EBITDA does not reflect these capital expenditures. Our adjusted EBITDA may not be comparable to similarly titled measures of other companies because they may not calculate adjusted EBITDA in the same manner as we calculate the measure, limiting its usefulness as a comparative measure. In evaluating adjusted EBITDA, you should be aware that in the future we will incur expenses similar to the adjustments in this presentation. Our presentation of adjusted EBITDA should not be construed as an inference that our future results will be unaffected by these expenses or any unusual or non-recurring items. When evaluating our performance, you should consider adjusted EBITDA alongside other financial performance measures, including our net loss and other GAAP results.

Key Metrics

We monitor the following key metrics to help us evaluate our business, identify trends affecting our business, formulate business plans and make strategic decisions. We believe the following metrics are useful in evaluating our business.

Our key metrics are as follows:

Estimated Value of Agreements(1)$76,671  $56,101  $284,502  $154,468 
(1) Previously referred to as total contract value               

Clients. We define our clients as business entities that have at least one active paid contract with us at the end of a particular period. Entities that access our platform through our channel partners, PBMs, and resellers are counted as individual clients. We do not count our channel partners, PBMs, or resellers as clients, unless they also separately have active paid contracts for our solutions. If business units or subsidiaries of the same entity enter into separate agreements with us, they are counted as separate clients. However, entities that have purchased multiple solutions through different contracts are treated as a single client.

Enrolled Diabetes Members. We believe our ability to grow the number of enrolled diabetes members is an indicator of penetration of our flagship solution, Livongo for Diabetes. We define our enrolled diabetes members as all individuals that are enrolled in Livongo for Diabetes at the end of a given period. This number excludes: (i) employees or dependents of a client that has ceased using our solution, (ii) employees who no longer have an employment relationship with an active client, and their dependents, and (iii) employees and dependents who have not been active on or used our solution for a period of time as specified in the applicable client’s agreement, which is typically between four and six months.

Estimated Value of Agreements. This represents the estimated value of agreements, signed in the relevant period and was previously referred to as the Total Contract Value (TCV) in certain of Livongo's previous filings with the Securities and Exchange Commission. Estimated Value of Agreements includes agreements entered into with new clients or expansion opportunities entered into with existing clients. Estimated Value of Agreements is helpful in evaluating our business because it provides some visibility into future revenue. Our new client subscriptions typically have a term of one to three years, and we generally invoice our clients in monthly installments at the end of each month in the subscription period based on the number of members in such month who were active on or used our solution within a certain period of time, as specified in the applicable client’s agreement. We define estimated value of agreements as contractually committed orders to be invoiced under agreements initially entered into during the relevant period. Agreements are only counted in estimated value of agreements in the period in which they are entered into, and for purposes of this calculation, we assume an average member enrollment rate. Our estimates include assumptions regarding the total recruitable individuals at a client, commencement of enrollment period, enrollment method, starting enrollment rates, monthly increases to enrollment rates over time, contract length, and client size and industry. Estimates also assume the agreement will not be terminated early and will be serviced for the full term, there are no changes to the total recruitable individuals at a client during the relevant period, and no changes to the per participant per month fee, or PPPM, during the relevant period. Until such time as these amounts are invoiced, which occurs at the end of each month of service, they are not recorded in revenue, deferred revenue, or elsewhere in our consolidated financial statements.
