Endurance International Group Reports 2013 Fourth Quarter and Full Year Results

BURLINGTON, MA (February 25, 2014) — Endurance International Group Holdings, Inc. (NASDAQ: EIGI), a leading provider of cloud-based platform solutions designed to help small and medium-sized businesses succeed online, today reported financial results for the fourth quarter and full year ended December 31, 2013.

“We’re excited to report another great quarter, capping off a truly historic year for our company. We demonstrated strong organic revenue growth while increasing adjusted EBITDA and unlevered free cash flow. Our company’s strategy is based on two simple principles: adding more high quality subscribers to our platform and selling our subscribers more value added solutions. During the year, we added over 279,000 net new subscribers, bringing our total number of subscribers to just over 3.5 million. Further, we continued to increase our average revenue per subscriber (ARPS), which grew to $13.15 for the quarter,” commented Hari Ravichandran, CEO and Founder of Endurance International Group.

Fourth Quarter Highlights

Full Year 2013 Highlights

Adjusted revenue, Adjusted EBITDA, UFCF, FCF and ARPS are non-GAAP financial measures. A reconciliation of these non-GAAP financial measures to their most comparable measure calculated in accordance with GAAP is provided in the financial statement tables included at the end of this press release. An explanation of these measures is also provided below under the heading “Use of Non-GAAP Financial Measures”.

On November 25, 2013, the company refinanced its bank debt, repaying its $315 million second lien term loan using proceeds from its initial public offering, cash on hand and an incremental first lien term loan facility. The new facility consists of a single tranche of first lien term debt of $1.05 billion, which will lower the company’s annualized term loan interest expense by approximately $35 million, based on the current loan balance and interest rates.

Recent Developments

On January 23, 2014, Endurance closed its acquisition of the web presence business of Directi Holdings, substantially expanding our footprint into emerging markets.

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.

We are including one non-GAAP financial measure in this earnings release, FCF, that we have not previously provided. We believe that reporting FCF will be helpful to investors because we believe FCF helps investors to gauge our ability to generate cash flow after taking into consideration cash interest associated with our indebtedness. In addition, in connection with adding this financial measure, we have revised the definitions of adjusted net income and adjusted EBITDA previously reported in our final prospectus filed with the SEC on October 25, 2013 pursuant to Rule 424(b) under the Securities Act in connection with our initial public offering and our Form 10-Q for the period ended September 30, 2013 filed with the SEC on December 6, 2013, since we believe that including these revisions is appropriate in order to reconcile cash flows from (used in) operating activities to FCF.

We believe that our revisions to the amounts previously reported for adjusted net income and adjusted EBITDA are not material.

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.

Adjusted Net Income

Adjusted net income is a non-GAAP financial measure that we calculate as consolidated 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 change in 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

3

believe highlighting cash collected and cash spent in a given period is valuable insight for 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 have substantial indebtedness primarily as a result of the December 2011 acquisition of a controlling interest in our company by investment funds and entities affiliated with Warburg Pincus and Goldman Sachs and a substantial dividend payment in November 2012. 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 unlevered free cash flow less interest expense. We believe that this presentation of free cash flow provides investors with an additional indicator of our ability to generate positive cash flows after meeting our obligations with regards 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 as if those acquired subscribers had been our subscribers since the beginning of the period presented. We believe that excluding fair value adjustments to deferred revenue is useful to investors because it shows our revenue prior to purchase accounting adjustments related to our acquisitions, and that including revenue from acquired subscribers in this manner provides a helpful comparison of the organic revenue generated from our subscribers from period to period.

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 from subscribers 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.
