Technology Research Corporation Announces Strong Third Fiscal Quarter
Results and Record Performance for the Nine-Month Period

    CLEARWATER, Fla.--(BUSINESS WIRE)--Jan. 20, 2004--Robert S.
Wiggins, Chairman and Chief Executive Officer of Technology Research
Corporation (TRC), (Nasdaq:TRCI) announced today that the Company's
operating revenues for the third quarter ended December 31, 2003 were
$5,805,556, compared to $4,582,284 reported in the same quarter last
year, an increase of 27% with military revenues increasing by
$958,773, commercial revenues by $255,834 and royalty income by
$8,665. Net income for the current quarter was $680,388, compared to
$311,963, for the same quarter last year, an increase of 118%. Basic
earnings were $.12 per share and diluted earnings were $.11 per share
for the current quarter compared to basic and diluted earnings of $.06
per share for the same quarter last year. The Company recorded
expenses of $137,923 in the quarter for new account setup and the
promotion of its Fire Shield(R) products in retail stores. In
addition, the Company recorded a non-recurring expense of
approximately $75,000 due to a change in its severance policy at its
Honduran subsidiary during the quarter.
    The Company's operating revenues for the nine-month period ended
December 31, 2003 were $17,678,125, compared to $12,406,418 reported
in the same period of the prior year, an increase of 42%. Net income
for the nine-month period was $2,058,348, compared to $647,549, for
the same period in the prior year, an increase of 218%. Basic earnings
were $.37 per share and diluted earnings were $.36 per share for the
nine-month period compared to basic and diluted earnings of $.12 per
share for the same period of the prior year.
    Mr. Wiggins commented, "The Company achieved its best performance
ever with record high revenues and net income through nine months. Our
manufacturing facilities continue to operate efficiently, and the
Company ended the quarter with $5,195,426 in cash and remained
debt-free." Mr. Wiggins added, "The outlook for the remainder of the
fiscal year continues to be positive."
    For the nine-month period ended December 31, 2003, commercial
revenues increased by $1,933,095, military revenues improved by
$3,358,171 and royalty income was down by $19,559 compared to the same
period of the prior year. The increase in commercial revenues was
primarily attributed to product sales of $1,008,831 into retail stores
and $450,000 to a major sprayer/washer manufacturer. New accounts in
the Recreational Vehicle, Brand Label and Commercial Distribution
markets contributed to the remainder of the growth. Military revenues
continue to be strong due to direct military shipments of support
parts for existing systems and control devices related to the Tactical
Quiet Generator (TQG) programs. The increase in direct military
shipments is primarily the result of current U.S. military activity.
    The Company continues to make progress in establishing its Fire
Shield(R) brand name. Fire Shield(R) product sales were $750,957, or
8.3% of commercial sales, for the nine-month period. In addition, the
Company recorded royalty income of $67,536 for the nine-month period
from Applica Inc., a licensee that incorporates a Fire Shield(R) cord
set on its line of Black & Decker(R) portable heaters. The Company's
patented Fire Shield(R) technology has numerous applications and
represents a significant opportunity for growth. One example is that
the Company is well-positioned to participate in the estimated $60
million annual market created by the 2002 National Electrical Code
(NEC) and the Underwriters Laboratories (UL) currently scheduled
requirement for cord fire protection on portable room air conditioners
which are manufactured after August 1, 2004. The Company's products
are currently under evaluation by a number of room air conditioner
manufacturers.
    The third quarter dividend of $.015 per share will be paid on
January 23, 2004 to shareholders of record on December 31, 2003. The
Company's annual dividend is expected to be $.06 per share.
