Dear Mr. Gilmore:

Endurance International Group Holdings, Inc. (“Endurance” or the “Company”) submits this letter in response to the comment regarding the above referenced filing contained in a letter dated December 31, 2014 from Patrick Gilmore, Accounting Branch Chief of the staff (the “Staff”) of the United States Securities and Exchange Commission (the “Commission”), to Hari Ravichandran, Chief Executive Officer of the Company.

1. We note you have added back dividend-related payments, transaction expenses and charges, and integration and restructuring expenses to arrive at your non-GAAP financial measure, “free cash flow.” Please note that since these charges require cash settlement, the exclusion of these charges is not appropriate. Please revise this non-GAAP financial measure accordingly. Refer to Item 10(e)(1)(ii)(A) of Regulation S-K.

performance of the Company’s business, identify trends affecting the Company’s business, develop projections and make strategic business decisions. The Company presents FCF and UFCF in its Forms 10-Q and 10-K filed with the Commission and in its earnings releases, investor conference calls and other investor communications in which financial and operating results are presented.

The Company presents UFCF because it believes that UFCF is a useful indicator of its operating performance. The Company presents FCF because it believes FCF provides investors with an additional indicator of the Company’s ability to generate positive cash flows after meeting its interest obligations on outstanding indebtedness.

The Company acknowledges the staff’s position as to the application of Item 10(e)(1)(ii)(A) of Regulation S-K to non-GAAP liquidity measures in reports filed with the Commission. The Company will remove FCF and UFCF from its future reports on Forms 10-Q and 10-K filed with the Commission.
