Use of Non-GAAP Financial Measures

In addition to our financial information presented in accordance with GAAP, we use certain “non-GAAP financial measures” described below to evaluate the operating and financial performance of our business, identify trends affecting our business, develop projections and make strategic business decisions. Generally, a non-GAAP financial measure is a numerical measure of a company’s operating performance, financial position or cash flow that includes or excludes amounts that are included or excluded from the most directly comparable measure calculated and presented in accordance with GAAP. We monitor the non-GAAP financial measures described below, and we believe they are helpful to investors, because we believe they reflect the operating performance of our business and help management and investors gauge our ability to generate cash flow, excluding some recurring and non-recurring expenses that are included in the most directly comparable measures calculated and presented in accordance with GAAP.

Our non-GAAP financial measures may not provide information that is directly comparable to that provided by other companies in our industry, as other companies in our industry may calculate non-GAAP financial results differently, particularly related to adjustments for integration and restructuring expenses. In addition, there are limitations in using non-GAAP financial measures because they are not prepared in accordance with GAAP, may be different from non-GAAP financial measures used by other companies and exclude expenses that may have a material impact on our reported financial results. Furthermore, interest expense, which is excluded from some of our non-GAAP measures, has been and will continue to be for the foreseeable future a significant recurring expense in our business. The presentation of non-GAAP financial information is not meant to be considered in isolation or as a substitute for the directly comparable financial measures prepared in accordance with GAAP. We urge you to review the reconciliations of our non-GAAP financial measures to the comparable GAAP financial measures included in this press release, and not to rely on any single financial measure to evaluate our business.

We have not reconciled our adjusted revenue, adjusted EBITDA or UFCF guidance to the most comparable GAAP metrics because we do not provide guidance for the reconciling items between these non-GAAP metrics and the most comparable GAAP metrics, as certain of these items are out of our control and/or cannot be reasonably predicted.

Adjusted Net Income

Adjusted net income is a non-GAAP financial measure that we calculate as net income (loss) plus (i) changes in deferred revenue inclusive of purchase accounting adjustments related to acquisitions, amortization, stock-based compensation expense, loss of unconsolidated entities, net loss on sale of property and equipment, expenses related to integration of acquisitions and restructurings, any dividend-related payments accounted for as compensation expense, transaction expenses and charges including costs associated with certain litigation matters, and preparation for our initial public offering, less (ii) earnings of unconsolidated entities and net gain on sale of property and equipment and (iii) the estimated tax effects of the foregoing adjustments. Due to our history of acquisitions and financings, we have incurred accounting charges and expenses that obscure the operating performance of our business. We believe that adjusting for these items and the use of adjusted net income is useful to investors in evaluating the performance of our company.

Adjusted EBITDA

Adjusted EBITDA is a non-GAAP financial measure that we calculate as adjusted net income plus interest expense, depreciation, and income tax expense (benefit). We manage our business based on the cash collected from our subscribers and the cash required to acquire and service those subscribers. We believe highlighting cash collected and cash spent in a given period provides insight to an investor to gauge the overall health of our business. Under GAAP, although subscription fees are paid in advance, we recognize the associated revenue over the subscription term, which does not fully reflect short-term trends in our operating results.

Unlevered Free Cash Flow

Unlevered free cash flow, or UFCF, is a non-GAAP financial measure that we calculate as adjusted EBITDA plus change in operating assets and liabilities (other than deferred revenue) net of acquisitions, less capital expenditures and income taxes excluding deferred tax. We believe the most useful indicator of our operating performance is the cash generating potential of our company prior to any accounting charges related to our acquisitions. We also invest in marketing, our largest operating expense, which may increase or decrease in a given period, depending on the cost of attracting new subscribers to our solutions. We also believe that because our business has meaningful data center and related infrastructure requirements, the level of capital expenditures required to run our business is an important factor for investors. We believe UFCF is a useful measure that captures the effects of these issues.

Free Cash Flow

Free cash flow, or FCF, is a non-GAAP financial measure that we calculate as UFCF less interest expense. We believe that this presentation of FCF provides investors with an additional indicator of our ability to generate positive cash flows after meeting our obligations with regard to payment of interest on our outstanding indebtedness.

Adjusted Revenue

Adjusted revenue is a non-GAAP financial measure that we calculate as GAAP revenue adjusted to exclude the impact of any fair value adjustments to deferred revenue resulting from acquisitions and to include the revenue generated from subscribers we added through business acquisitions. Historically, we adjusted the amount of revenue to include the revenue generated from subscribers we added through business acquisitions as if those acquired subscribers had been our subscribers since the beginning of the period presented. Since the first quarter of 2014, we have adjusted the amount of revenue to include the revenue generated from subscribers we add through business acquisitions from the date of the relevant acquisition. We believe that excluding fair value adjustments to deferred revenue is useful to investors because it shows our revenue prior to purchase accounting charges related to our acquisitions, and that including revenue from acquired subscribers in this manner provides a helpful comparison of the revenues generated from our subscribers from period to period.

Total Subscribers

We define total subscribers as those that, as of the end of a period, are subscribing directly to our web presence solutions on a paid basis. Historically, in calculating total subscribers, we include the number of end-

of-period subscribers we added through business acquisitions as if those subscribers had subscribed with us since the beginning of the period presented. Since the first quarter of 2014, we have included subscribers we added through business acquisitions from the date of the relevant acquisition. We believe including acquired subscribers in this manner provides a useful measure of the number of subscribers we added during a period. We do not include in total subscribers accounts that access our solutions via resellers or purchase only domain names from us. Subscribers of more than one brand are counted as separate subscribers. We believe total subscribers is an indicator of the scale of our platform and our ability to expand our subscriber base, and is a critical factor in our ability to monetize the opportunity we have identified in serving the SMB market.

Average Revenue per Subscriber

Average revenue per subscriber, or ARPS, is a non-GAAP financial measure that we calculate as the amount of adjusted revenue we recognize in a period divided by the average of the number of total subscribers at the beginning of the period and at the end of the period. We believe ARPS is an indicator of our ability to optimize our mix of products and services and pricing, and sell products and services to new and existing subscribers.
