Raises Earnings Guidance Again to at Least $2.20 Per Share

    HAMPSTEAD, Md.--(BUSINESS WIRE)--Feb. 5, 2004--JoS. A. Bank
Clothiers, Inc. (Nasdaq National Market:JOSB) announces it has
increased its earnings guidance for the fiscal year ended January 31,
2004 (FY2003). After reporting better-than-expected sales for the
fiscal month of January earlier today, the Company now expects to
report minimum net income of approximately $16.3 million for FY2003,
which would represent an increase of at least 49% when compared with
the reported net income of $10.9 million in FY2002. In addition, the
Company expects earnings per share of at least $2.20 for FY2003
compared with the reported earnings per share of $1.55 in FY2002.
    "Our strategy of high quality, superior service, product
innovation and a commitment to being in-stock on basic merchandise
continues to be on target," said Robert N. Wildrick, Chief Executive
Officer of JoS. A. Bank Clothiers, Inc. "Our brand has become
increasingly accepted as the leading quality-status menswear brand by
our existing and new customers across the nation through both our
stores and our direct sales channel (catalog and internet). We have
210 stores in 35 states and will continue to open approximately one
store a week as we did last year."
    "Based upon stronger than expected sales and gross profit margins
in January, we are again raising our earnings guidance for FY2003 to
at least $2.20 per share," continued Mr. Wildrick. "This compares with
our previous guidance of $2.04 per share and reported earnings per
share of $1.55 in FY2002."
    All per share amounts noted above represent diluted earnings per
share and are based on the number of shares outstanding before the
impact of a 50% stock dividend that was announced on January 14, 2004
and is to be distributed to shareholders on February 18, 2004.
