                   UNIFIRST ANNOUNCES RECORD FINANCIAL RESULTS
                  FOR FISCAL 2004 FOURTH QUARTER AND FULL YEAR


Wilmington, MA (October 26, 2004) - UniFirst Corporation (NYSE:UNF) today
announced record revenues and earnings for its fiscal 2004 fourth quarter and
full year, which ended August 28, 2004.

For fiscal 2004, revenues were a record $719.4 million, the highest in the
Company's 68 year history and a 20.5 percent increase from $596.9 million in
fiscal 2003. Acquisitions, primarily Textilease, accounted for 14.7 percent of
this revenue growth. Income before cumulative effect of accounting change was
$33.6 million, a 14.7 percent increase from last year's $29.3 million. In the
first quarter of fiscal 2003 the Company recorded an expense of $2.2 million,
net of tax, as a result of implementing SFAS 143 regarding long lived assets.
Net income for fiscal 2004 was $33.6 million, a 24.3 percent increase from last
year's $27.0 million.

Revenues for the fourth quarter of fiscal 2004 were $178.1 million, a 20.6
percent increase from $147.6 million in the same period a year ago.
Acquisitions, again primarily Textilease, accounted for 14.5 percent of the
revenue growth for the quarter. Fourth quarter net income was $7.5 million, a
4.2 percent increase from last year's $7.2 million.

Since the Company has two classes of common stock with a dividend differential,
GAAP (in accordance with EITF 03-06) now requires the Company to report net
income per share separately for each class of stock. Management believes that
the historical method of reporting net income per share on the "if converted
method", which is now a non GAAP financial measure, is more meaningful since the
Class B Common Stock is freely convertible at any time into an equal number of
shares of Common Stock. Under the "if converted method", the net income per
basic share for fiscal 2004 would have been $1.75 which is consistent with the
high end of the Company's guidance in our last conference call.

Under the new dual class reporting method the basic income per Common share
before cumulative effect of accounting change was $1.95 for fiscal 2004 or 14.0%
greater than the $1.71 computed on the same basis in the prior year. The basic
income per share for the Class B Common stock was $1.56 as compared to $1.37 in
the prior year.

Under the new dual class reporting method the basic net income per Common share
was $0.44 for the fourth quarter of fiscal 2004 or 5.0%





greater than the $0.42 computed on the same basis in the prior year. For the
same period the basic net income per share for the Class B common stock was
$0.35 as compared to $0.34 in the prior period.

"Fiscal 2004 was our 36th consecutive year of record revenues," said Ronald D.
Croatti, UniFirst's President and Chief Executive Officer. "The Textilease
integration is proceeding on schedule and the Company did an excellent job
controlling operating expenses. Overall I was very pleased with our results in a
difficult economy."

The Company will hold a conference call today at 4:00 PM (EST) to discuss its
quarterly and annual financial results, business highlights and outlook. A
simultaneous live webcast of the call will be available over the Internet, and
replays of the webcast will be available until November 27, 2004. The webcast
can be accessed at www.unifirst.com.
