Conference Call
Blue Nile will host a conference call to discuss its second quarter 2007 financial results at 2:00 p.m. Pacific time today. A live webcast of the conference call may be accessed at http://investor.bluenile.com. Following the completion of the call, a recorded replay of the webcast will be available for 30 days at the same Internet address. This call will contain forward-looking statements and other material information regarding the Company’s financial and operating results. In the event that any non-GAAP financial measure is discussed on the conference call that is not described in this release, related complementary information will be made available at http://investor.bluenile.com as soon as practicable after the conclusion of the conference call.

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 free cash flow as a measure of certain components of financial performance. 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’s management does not itself, nor does it suggest that investors should, consider such non-GAAP financial measure in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. Investors should also note that the non-GAAP financial measure used by Blue Nile may not be the same non-GAAP financial measure, and may not be calculated in the same manner, as that of other companies. Whenever Blue Nile uses such non-GAAP financial measure, it provides a reconciliation of the non-GAAP financial measure to the most closely applicable GAAP financial measure. Investors are encouraged to review the related GAAP financial measure and the reconciliation of the non-GAAP financial measure to its most directly comparable GAAP financial measure.

Blue Nile’s management believes that non-GAAP free cash flow provides meaningful supplemental information regarding liquidity. Blue Nile believes that both management and investors benefit from referring to this non-GAAP measure in assessing the performance of Blue Nile and when planning and forecasting future periods. Further, management believes that the inclusion of the non-GAAP free cash flow calculation provides consistency in Blue Nile’s financial reporting and comparability with similar companies in Blue Nile’s industry.
