Non-GAAP Financial Measures and Key Metrics

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."

In addition, we calculate and present certain key business metrics that we believe are useful in evaluating our business. For a description of these key metrics, including the reasons management uses each measure, please see the section of the tables titled "Key Metrics."

About Non-GAAP Financial Measures

In addition to our financial results determined in accordance with U.S. Generally Accepted Accounting Principles (GAAP), we believe non-GAAP measures are useful in evaluating our operating performance. In particular, we believe that the use of non-GAAP net income (loss), adjusted gross profit, adjusted gross margin, 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 Income (Loss)

We define non-GAAP net income (loss) as net loss less (i) stock-based compensation expense, (ii) amortization of intangible assets, (iii) employer payroll taxes on stock-based compensation, (iv) change in fair value of contingent consideration, (v) non-cash interest expense on our convertible senior notes, and (vi) tax impact. Prior to the second quarter of 2020, the employer portion of payroll taxes on stock-based compensation was insignificant and therefore we have not historically excluded such amounts from non-GAAP net income (loss). However, because the amount of stock-based compensation expense has increased in the ordinary course of business, the employer payroll taxes on our stock-based compensation has also increased and become more meaningful. We believe that, similar to stock-based compensation expense, such payroll taxes are unrelated to overall operating performance and therefore we have determined to exclude such amounts from non-GAAP net income loss) beginning with the second quarter of 2020. We are making this update to our presentation prospectively for the second quarter of 2020 and have not updated any prior periods because such amounts were insignificant.

Non-GAAP net income (loss) is used by our management to understand and evaluate our operating performance and trends. We believe that non-GAAP net income (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 income (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.

(1)   As noted above, beginning in the second quarter of 2020, we made a prospective update to our presentation of non-GAAP net income to exclude (i.e., add back) the employer portion of payroll taxes on stock-based compensation. As such, the non-GAAP net income presented above for the six months ended June 30, 2020 excludes our portion of payroll taxes on stock-based compensation from the second quarter of 2020. We have not updated any prior periods. The employer portion of payroll taxes on stock-based compensation was $1,555 for the three months ended March 31, 2020; as such, non-GAAP net income would have been $17,959, and non-GAAP diluted net income per share attributable to common stockholders would have been $0.16, for the six months ended June 30, 2020 had this update been made on a retroactive basis back to the first quarter of 2020.

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 (i) stock-based compensation expense, (ii) amortization of intangible assets, and (iii) employer payroll taxes on stock-based compensation. Prior to the second quarter of 2020, the employer portion of payroll taxes on stock-based compensation was insignificant and therefore we have not historically excluded such amounts from adjusted gross profit and adjusted gross margin. However, because the amount of stock-based compensation expense has increased in the ordinary course of business, the employer payroll taxes on our stock-based compensation has also increased and become more meaningful. We believe that, similar to stock-based compensation expense, such payroll taxes are unrelated to overall operating performance and therefore we have determined to exclude such amounts from adjusted gross profit and adjusted gross margin beginning with the second quarter of 2020. We are making this update to our presentation prospectively for the second quarter of 2020 and have not updated any prior periods because such amounts were insignificant.

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 the above-referenced items as factors unrelated to overall operating performance. The following table presents a reconciliation of adjusted gross profit from the most comparable GAAP measure, gross profit, for the periods presented:

  Three Months Ended June 30, Six Months Ended June 30,
  2020 2019 2020 2019
  (dollars in thousands)
Gross profit $70,457  $28,951  $121,173  $51,155 
Add:        
Stock-based compensation expense 118  6  210  12 
Amortization of intangible assets 420  353  840  680 
Employer payroll tax on stock-based compensation(1) 27    27   
Adjusted gross profit $71,022  $29,310  $122,250  $51,847 
Adjusted gross margin (as a percentage of revenue) 77.3% 71.6% 76.1% 71.0%

(1)    As noted above, beginning in the second quarter of 2020, we made a prospective update to our presentation of adjusted gross profit and adjusted gross margin to exclude (i.e., add back) the employer portion of payroll taxes on stock-based compensation. As such, the adjusted gross profit and adjusted gross margin presented above for the three and six months ended June 30, 2020 excludes our portion of payroll taxes on stock-based compensation from the second quarter of 2020 recorded as a component of cost of revenue. We have not updated any prior periods. The employer portion of payroll taxes on stock-based compensation was $23 for the three months ended March 31, 2020; as such, adjusted gross profit would have been $122,273, and adjusted gross margin (as a percentage of revenue) would have been 76.1%, for the six months ended June 30, 2020 had this update been made on a retroactive basis back to the first quarter of 2020.


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) employer payroll taxes on stock-based compensation, (v) acquisition-related expenses, (vi) change in fair value of contingent consideration, (vii) other income, net, and (viii) provision for (benefit from) income taxes. Prior to the second quarter of 2020, the employer portion of payroll taxes on stock-based compensation was insignificant and therefore we have not historically excluded such amounts from adjusted EBITDA. However, because the amount of stock-based compensation expense has increased in the ordinary course of business, the employer payroll taxes on our stock-based compensation has also increased and become more meaningful. We believe that, similar to stock-based compensation expense, such payroll taxes are unrelated to overall operating performance and therefore we have determined to exclude such amounts from adjusted EBITDA beginning with the second quarter of 2020. We are making this update to our presentation prospectively for the second quarter of 2020 and have not updated any prior periods because such amounts were insignificant.

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

  Three Months Ended June 30, Six Months Ended June 30,
  2020 2019 2020 2019
  (in thousands)
Net (loss) $(1,554) $(12,977) $(7,127) $(27,348)

Amortization of intangible assets 692  629  1,388  1,193

______________
(1)   Depreciation and amortization includes depreciation of property and equipment, amortization of debt discount, and amortization of capitalized internal-use software costs.
(2)   As noted above, beginning in the second quarter of 2020, we made a prospective update to our presentation of adjusted EBITDA to exclude (i.e., add back) the employer portion of payroll taxes on stock-based compensation. As such, the adjusted EBITDA presented above for the three and six months ended June 30, 2020 excludes our portion of payroll taxes on stock-based compensation from the second quarter of 2020. We have not updated any prior periods. The adjusted EBITDA presented above for the six months ended June 30, 2020 also excludes the employer portion of payroll taxes paid in connection with the stock releases upon the expiration of the lock-up agreement related to our IPO because such payroll taxes were a one-time occurrence in the three months ended March 31, 2020. The employer portion of payroll taxes on stock-based compensation was $1,555 for the three months ended March 31, 2020; as such, adjusted EBITDA would have been $18,655 for the six months ended June 30, 2020 had this update been made on a retroactive basis back to the first quarter of 2020.
(3)   Acquisition-related expenses consist primarily of transaction and transition related fees and expenses, including legal, accounting, and other professional fees.
(4)   Other income (expense), net includes interest (expense) income, and other (expense) income.


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:

  Three Months Ended June 30, Six Months Ended June 30,
  2020 2019 2020 2019
  (dollars in thousands)
Clients(1) 1,328  758  1,328  758 
Enrolled Diabetes Members 410,270  192,934  410,270  192,934 
Estimated Value of Agreements(2) $108,705  $74,234  $197,713  $122,297 

(1)   First quarter and first half of 2019 has been updated to conform to current methodology as described further below.
(2)   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, such as PBMs and resellers, are counted as individual clients. Historically, we have treated our partnerships with health plans as a single client, though multiple employers may contract for our services through a single health plan, because of the relatively small number of employers who enrolled under those plans. Because of the increase in the number of employers who are enrolling through health plans instead of other channels, beginning with the first quarter of 2020 we believe that it is more appropriate to treat health plans in the same manner as we treat our channel partners, such as PBMs and resellers, and include entities who enroll in our platform through a health plan as separate clients. The historical information presented has been revised to include such entities as individual clients. We do not count our channel partners, such as PBMs, health plans, 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 (EVA). This represents the estimated value of agreements, signed in the relevant period and was previously referred to as the Total Contract Value, or 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 expansions 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 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.
