Selected Publicly Traded Companies Analysis

BofA Merrill Lynch reviewed publicly available financial and
stock market information for Blue Nile and the following 10
publicly traded companies in the eCommerce and jewelry retail
industries:

BofA Merrill Lynch reviewed, among other things, enterprise
values of the selected publicly traded companies, calculated as
equity

values based on closing stock prices on November 4, 2016, plus
debt and preferred stock and minority interests, less cash and
cash equivalents, as a multiple of calendar year 2017 estimated
earnings adjusted to exclude the effects of stock-based
compensation expense before interest, taxes, depreciation and
amortization, commonly referred to as adjusted EBITDA. BofA
Merrill Lynch also reviewed the per share equity values of the
selected publicly traded companies, based on closing stock prices
on November 4, 2016, as a multiple of calendar year 2017
estimated cash earnings per share, and the market capitalization
of the selected publicly traded companies, based on closing stock
prices on November 4, 2016, as a multiple of calendar year 2017
estimated free cash flow. This analysis indicated the following
multiples for the selected publicly traded companies:

BofA Merrill Lynch then applied (i) a range of enterprise value
to adjusted EBITDA multiples of 7.5x to 13.5x, based on the
selected publicly traded companies, to Blue Niles calendar year
2017 estimated adjusted EBITDA; (ii) a range of price to cash
earnings per share multiples of 14.0x to 27.0x, based on the
selected publicly traded companies, to Blue Niles calendar year
2017 estimated cash earnings per share; and (iii) a range of
price to free cash flow multiples of 10.0x to 20.0x, based on the
selected publicly traded companies, to Blue Niles calendar year
2017 estimated free cash flow. Estimated financial data of the
selected publicly traded companies were based on publicly
available research analysts estimates, and estimated financial
data of Blue Nile were based on the Management Projections. This
analysis indicated the following approximate implied per share
equity value reference ranges for Blue Nile, rounded to the
nearest $0.05, as compared to the Per Share Price:

No company used in this analysis is identical or directly
comparable to Blue Nile. Accordingly, an evaluation of the
results of this analysis is not entirely mathematical. Rather,
this analysis involves complex considerations and judgments
concerning differences in financial and operating characteristics
and other factors that could affect public trading or other
values of the companies to which Blue Nile was compared.

the following multiples for the selected precedent transactions:

BofA Merrill Lynch then applied last twelve month adjusted EBITDA
multiples of 10.0x to 18.0x, derived from the selected
transactions, to Blue Niles last twelve month adjusted EBITDA as
of October 2, 2016. Estimated financial data of the selected
transactions were based on publicly available information at the
