Non-GAAP Financial Measures

To supplement Blue Nile's consolidated financial statements presented in accordance with generally accepted accounting principles ("GAAP"), Blue Nile uses non-GAAP adjusted EBITDA and non-GAAP free cash flow as measures of certain components of financial performance. Blue Nile defines non-GAAP adjusted EBITDA as earnings before interest and other income, taxes, depreciation and amortization, adjusted to exclude the effects of stock-based compensation expense. Blue Nile defines non-GAAP free cash flow as net cash provided by (used in) operating activities less cash outflows for purchases of fixed assets, including internal-use software and website development. Blue Nile reports sales information in accordance with GAAP. Internally, management monitors its sales performance on a non-GAAP basis that eliminates the positive or negative effects that result from translating international sales into U.S. dollars (the "constant exchange rate basis"). Blue Nile's management does not itself, nor does it suggest that investors should, consider such non-GAAP financial measures in isolation from, or as a

substitute for, financial information prepared in accordance with GAAP. Investors should also note that the non-GAAP financial measures used by Blue Nile may not be the same non-GAAP financial measures, and may not be calculated in the same manner, as that of other companies. Whenever Blue Nile uses such non-GAAP financial measures, it provides a reconciliation of non-GAAP financial measures to the most closely applicable GAAP financial measures. 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.

Blue Nile's management believes that non-GAAP adjusted EBITDA and non-GAAP free cash flow, as defined, as well as international sales on a constant exchange rate basis provide meaningful supplemental information to the company and to investors. Blue Nile believes that both management and investors benefit from referring to these non-GAAP measures in assessing the performance of Blue Nile and when planning and forecasting future periods. Further, management believes that the inclusion of the non-GAAP adjusted EBITDA and non-GAAP free cash flow calculations provide consistency in Blue Nile's financial reporting and comparability with similar companies in Blue Nile's industry. Management believes the constant exchange rate measurement provides a more representative assessment of the sales performance and provides better comparability between reporting periods.
