    SALT LAKE CITY--(BUSINESS WIRE)--Oct. 19, 2004--USANA Health
Sciences Inc. (NASDAQ:USNA)

    --  Net Sales up 30.8%

    --  EPS up 39.3%

    --  Record Operating Margin

    --  Company provides preliminary 2005 guidance

    USANA Health Sciences Inc. (NASDAQ:USNA) today announced record
net sales of $68.7 million for the third quarter ended Oct. 2, 2004.
Net sales for the period increased 30.8% from $52.5 million in the
third quarter of 2003. The company reported record operating income
for the quarter of $12.1 million, compared to $8.5 million in the
third quarter of 2003. The company also achieved record operating
margin of 17.7% in the third quarter, compared to 16.2% in third
quarter of 2003.
    Net earnings in the third quarter were $8.0 million, up 32.0% from
$6.1 million in the third quarter of 2003. Earnings per share
increased in the third quarter to $0.39 per share, up 39.3% from $0.28
per share for the third quarter of 2003. This $0.39 earnings per share
includes a $0.01 increase from the one-time use of Research and
Development tax credits and a $0.02 decrease due to foreign currency
fluctuations.
    USANA's total number of active Associates increased in the third
quarter of 2004 to 111,000, up 27.6% from 87,000 in the third quarter
of 2003. Preferred Customers increased to 60,000 in the quarter, up
22.4% from 49,000 in the third quarter of 2003.
    For the nine-month period ended Oct. 2, 2004, net sales were
$197.7 million, up 40.7% from $140.5 million in the same period of
2003. Net earnings for that nine-month period were $21.6 million, up
54.7% from $14 million for the same period of 2003. Earnings per share
for the current nine-month period were $1.05, up 59.1% from $0.66 for
the same period of 2003.
    "The U.S. market continues to lead the way," said Dave Wentz,
USANA's president, "with net sales growth of 23% compared to the third
quarter of last year. Canada reported strong net sales in the quarter,
up nearly 17% over last year's third quarter. The number of active
Associates worldwide grew 27.6% compared to last year, reflecting our
continued effort to recognize, develop and support our sales leaders.
We're pleased with the consistent growth our company has been able to
generate during the past two years, and we believe we are well
positioned to grow in 2005."
    Another highlight of the quarter was USANA's annual international
convention held in Salt Lake City in mid-September. The September
convention marked the largest gathering of USANA Associates ever held.
The company announced the re-formulation of Sense(TM), its innovative
and popular skin and personal care product line.
    "We took another step forward to solidify our position in the skin
and personal care industry through the recent launch of the new Sense
line," continued Wentz. "Our new patent-pending, self-preserving
technology allows our products to be formulated without adding
parabens. We believe we now have a line of skin and personal care
products that will attract a new category of Associates who are
focused on building a home-based business with Sense.
    "The enthusiasm and excitement for the new Sense products among
the Associates during the convention was tremendous. Due to higher
than anticipated demand for Sense, some of our products sold out, and
we were not able to ship all of the orders before the end of the third
quarter. In response to this, we have increased production at our
Wasatch facility to meet the demand. Over the next several weeks, we
will continue launching our new, innovative Sense products in each of
our international markets."
    Commenting on USANA's financial performance, Gilbert A. Fuller,
chief financial officer, noted, "The third quarter marked the ninth
consecutive quarter of record sales. We achieved year-over-year
double-digit growth in all our markets except South Korea. Our largest
market, the U.S., continued to excel, with sales of $28.8 million,
compared to $23.4 million in the third quarter of 2003. Operating
margin in the quarter improved 150 basis points to 17.7%, compared to
last year's third quarter. We continue to gain incremental operating
leverage through top-line growth and internal cost controls.
    "Looking ahead to the remainder of 2004," continued Fuller, "we
still expect net sales for full year 2004 to approach $270 million. We
previously announced that we expected earnings per share for the full
year 2004 of $1.42 to $1.44. Now we expect that earnings per share for
the full year will be as much as $1.46.
    "As we take our first look at 2005," Fuller continued, "we believe
that net sales will grow between 15% and 18%, which includes revenue
from the proposed opening of one new market before the end of the
third quarter of 2005. We expect earnings per share in 2005 to grow
between 20% and 25%. These preliminary 2005 estimates exclude any
sales from our potential entry into China. Our time frame for opening
China remains uncertain because the regulations that will govern
network marketing in the region have not yet been finalized."
    USANA executives will hold a conference call and live webcast to
discuss this announcement with investors on Oct. 20, 2004, at 11 a.m.
EDT. Investors may listen to the call by accessing USANA's Web site at
