   JoS. A. Bank Clothiers Reports 13.8% Increase in January Sales;
             Company Raises Earnings Guidance to at Least
                 $1.71 Per Share for Fiscal Year 2004

    HAMPSTEAD, Md.--(BUSINESS WIRE)--Feb. 3, 2005--JoS. A. Bank
Clothiers, Inc. (Nasdaq National Market:JOSB) announces that its total
sales for the fiscal month ended January 29, 2005 (fiscal January
2004) increased 13.8% to $23.9 million, compared with $21.0 million in
fiscal January 2004.
    The Company also reported record sales for the fourth quarter and
full fiscal year. Total sales for the fourth quarter of fiscal year
2004 increased 26.8% to $127.9 million, compared with sales of $100.9
million in the prior year period. Total sales for fiscal year 2004
increased 24.3% to $372.5 million, compared with sales of $299.7
million in the previous fiscal year.
    Comparable store sales rose 9.4% in the fourth quarter and 8.4% in
fiscal year 2004, while combined catalog and internet sales increased
31.0% and 22.7%, in the fourth quarter and fiscal year 2004,
respectively. Comparable store sales decreased 5.7% in January 2005,
while direct segment sales increased 42.8%, when compared with the
prior-year month.
    As a result of increased gross profit margins and strong sales in
the direct segment (catalog and internet) in January, the Company
announced that it expects to achieve at least the $1.71 earnings per
share "consensus" of published analyst estimates for the fiscal year
2004 (ended January 29, 2005). The minimum $1.71 earnings per share
guidance for the fiscal year 2004 represents a 43% increase over the
$1.20 earnings per share for the fiscal year 2003 (ended January 31,
2004).
    "We entered January in a very clean inventory position, which
enabled us to focus on maximizing gross profit margin throughout the
month," stated David E. Ullman, Chief Financial Officer of JoS. A.
Bank. "Our sales started very positive in January. However, sales were
severely impacted by the snow storms throughout the country mid-month
and ice storms in the southeast in the latter part of the month. Our
direct segment, which is typically not affected by weather, continued
to post double-digit sales gains."
    The Company also noted that it has decided to modify its
comparable store sales calculation methodology in 2005. Historically,
JoS. A. Bank has included new stores in its comparable store base at
the end of the first full fiscal year after opening. Existing stores
have been excluded from the comparable store sales if a new store has
opened in their immediate market area (within zero to ten miles)
during the previous twelve months. Because of the Company's store
expansion strategy, which emphasizes the opening of stores in existing
as well as new markets, management believes this method of calculating
comparable store sales accurately reflects relevant sales trends. In
future periods, comparable store sales will include merchandise sales
generated in all full-line stores that have been open for at least
thirteen full months, including retail locations that have had a new
JoS. A. Bank store open in their immediate market area (within zero to
ten miles) during the previous twelve months, similar to other
specialty stores.
    If the Company had calculated its comparable store sales using
this new methodology, the comparable store sales increase for fiscal
year 2004 would have approximated 7.5%, versus the 8.4% noted above, a
difference of nine-tenths of one percentage point. For the fiscal year
2003, the Company previously reported a gain of 8.2% in comparable
store sales. If the Company had calculated its comparable store sales
using the new methodology, the increase in comparable store sales for
fiscal year 2003 would have been approximately 7.5%, a difference of
seven-tenths of one percentage point. Total sales would remain the
same under either method, an increase of 24.3% in 2004 and 23.1% in
2003.
    All earnings per share amounts noted herein refer to diluted
earnings per share and reflect the impact of two stock dividends
distributed in 2004.

    The Company will report its fourth quarter and fiscal year 2004
earnings on April 4, 2005. A conference call to discuss the earnings
press release will be held on Monday, April 4, 2005 at 11:00 a.m.
