       USANA Announces Record Second Quarter Sales and Profits

    SALT LAKE CITY--(BUSINESS WIRE)--July 19, 2005--

       Net Sales up 22 Percent; Earnings Per Share up 33 Percent

    USANA Health Sciences Inc. (NASDAQ:USNA) today announced record
financial results for the second fiscal quarter of 2005 (ended July 2,
2005). The company achieved record net sales in the second quarter of
$82 million, an increase of 22%, compared with $67.2 million in the
second quarter of 2004. This growth was primarily driven by a 20%
increase in the number of active associates and double-digit,
year-over-year net sales gains achieved in all but one of the
company's 12 markets.
    Earnings from operations in the second quarter of 2005 grew 31.3%
to $14.7 million, or 18% of net sales, compared with $11.2 million, or
16.7% of net sales, in the second quarter of 2004. The company
achieved net earnings in the second quarter of 2005 of $9.5 million,
an increase of 28.7%, compared with net earnings of $7.4 million in
the second quarter of 2004. Earnings per share in the second quarter
increased to $0.48 per share, an increase of 33.3%, compared with
$0.36 per share in the second quarter of 2004.
    For the six-month period ended July 2, 2005, net sales were $158.6
million, an increase of 22.9%, compared with $129 million in the first
six months of 2004. Earnings from operations for the first six months
of 2005 were $28.3 million, an increase of 38.2%, compared with $20.5
million for the same period in 2004. The company achieved net earnings
in the first six months of 2005 of $18.5 million, an increase of
35.6%, compared with net earnings of $13.6 million in the first six
months of 2004. Earnings per share increased 41% in the first six
months of 2005 to $0.93, compared with $0.66 in the first six months
of 2004.
    During the second quarter, the company, through its current share
buyback program, purchased and retired 353,000 shares for an
investment of $15 million. Approximately $25 million remains under the
share buyback authorization.
    "We are pleased to report our 12th consecutive quarter of record
net sales," said Dave Wentz, president of USANA. "On a year-over-year
basis, we achieved double-digit growth in all but one of our 12
markets. Mexico was a particularly strong performer in the quarter,
posting sales gains of over 76% and associate growth of 80%, compared
with the same period in the prior year. In addition, Taiwan and
Singapore both posted impressive revenue growth of 38%. In line with
sales, the number of active associates grew to 125,000, an increase of
20%, compared with the second quarter of last year. Furthermore, sales
grew sequentially in all of our markets.
    "We continue to execute our strategy to increase sales in our
existing markets," continued Wentz. "In the third quarter, we will
begin an initiative of increasing the investment in our associates. We
believe this initiative will bring additional associates into the
business and accelerate our top-line growth. We also continue to
prepare for opening a new market, which we now believe will occur in
the fourth quarter."
    Gilbert A. Fuller, USANA's chief financial officer, said, "We
achieved another outstanding quarter for both sales and earnings.
Operating profit improved both year over year and sequentially in the
second quarter to 18% of net sales. This improvement was primarily
driven by proportionately lower SG&A expenses.
    "To update our guidance," Fuller continued, "we expect net sales
in the third quarter of 2005, typically our slowest quarter of
sequential growth, to be $82 million to $84 million, an increase of as
much as 22%, compared with $68.7 million in the third quarter of last
year. We also expect earnings per share in the third quarter of 2005
to be $0.47 to $0.49, as we begin our initiative to provide additional
incentives to our associates. In addition, we are increasing our
previously announced guidance for 2005. We now believe that net sales
for the full year will be between $325 million and $330 million. This
represents sales growth of 19% to 21%, compared with 2004. Finally, we
now believe earnings per share for 2005 will be between $1.88 and
$1.92, representing growth of 25% to 27%, compared with 2004."
    USANA will hold a conference call and webcast to discuss this
announcement with investors on Wednesday, July 20, 2005, at 11 a.m.
