National Dentex Corporation Announces Second Quarter 2003 Results

    WAYLAND, Mass.--(BUSINESS WIRE)--July 24, 2003--National Dentex
Corporation (NASDAQ: NADX), one of the largest owner/operators of
dental laboratories in the United States, today announced its results
for the second quarter ended June 30, 2003. Sales for the quarter
totaled $25,182,000 compared with $25,197,000 a year earlier. Net
income for the quarter was $1,650,000 or $.48 per share on a diluted
basis versus $1,871,000 or $.52 per share on a diluted basis in 2002.
    For the six months ended June 30, 2003, sales were $49,147,000
compared to $48,611,000 for the same period in 2002. Net income was
$2,982,000 or $.86 per diluted share compared to $3,440,000 or $.95
per share on a diluted basis in 2002.
    David Brown, President and CEO stated: "The laboratory segment of
the dental industry, particularly the crown and bridge area, has been
soft throughout 2003. We believe that a portion of this segment can be
temporarily deferred by patients, but in fact is eventually required
and is done. In this environment, in a labor intensive industry such
as ours, we are forced to look at labor costs in order to minimize the
impact of the slowdown in sales growth. We recently completed a review
of staffing at all of our laboratories in order to control this major
expense and its related components. We anticipate that this effort
will begin to impact our operating results in the second half of the
year.
    Mr. Brown further added: "Another area we must take advantage of
in this environment is our acquisition program. We are finding our
opportunities to acquire quality laboratories increasing. Several
weeks ago we announced the acquisition of Salem Dental Laboratory in
Cleveland, Ohio, a laboratory with over $2,000,000 of annual revenues
and an outstanding, long term reputation in its marketplace. Also,
this week we signed a letter of intent to acquire another laboratory
of similar size to Salem Dental. This acquisition is subject to the
completion of due diligence and the execution of definitive
agreements, with a closing anticipated on or about September 1, 2003.
    Mr. Brown concluded: "With acquisitions such as these, a
continuing focus on cost controls, in particular labor and labor
related costs, and our national marketing campaign, the NDX
Reliance(TM) Program, we believe we will be able to make up the year
to date shortfall in earnings of $.09 per share and produce an annual
earnings per share number for 2003 equal to the $1.66 in 2002. While
this is down from our guidance issued in November 2002, we believe
that this level of performance in light of the current business
climate, will position the Company for future growth opportunities as
industry trends improve."

18,000 dentists through dental laboratories located in 28 states.
