National Dentex Corporation Announces Fourth Quarter and Full Year 2004 Results

    WAYLAND, Mass.--(BUSINESS WIRE)--Feb. 25, 2005--National Dentex
Corporation (NASDAQ: NADX), one of the largest owner/operators of
dental laboratories in the United States, today announced its results
for the fourth quarter and year ended December 31, 2004. Sales for the
quarter totaled $27,599,000 compared with $25,768,000 a year earlier.
Net income for the quarter was $708,000 or $.13 per share on a diluted
basis compared to $1,498,000 or $.28 per share on a diluted basis in
2003.
    For the full year ended December 31, 2004, sales were $111,753,000
compared to $99,274,000 for the same period in 2004. Net income was
$5,450,000 or $1.00 per share on a diluted basis compared to
$5,757,000 or $1.10 per share on a diluted basis for the comparable
period of 2003.
    Commenting on the past year, David Brown, President and CEO,
stated: "Fiscal year 2004 was a unique and challenging one for
National Dentex. Operationally we made significant progress,
increasing our gross profit by over $5,000,000. This improvement came
as we continued to focus our internal efforts on the training of our
technicians and sharing best production practices across our system.
We continued to invest in our Reliance(TM) brand as a way to
differentiate our products and services, making them more relevant and
valuable to our customers. In our fragmented and intensely competitive
industry our success at differentiating ourselves in a professional
manner will allow us to become a truly valued participant in the
dentist - laboratory relationship.
    "The year also saw the Company under tremendous cost pressure
regarding the internal control compliance requirements of Section 404
of the Sarbanes - Oxley Act. This process, due to our structure of 40
locations across the country, proved to be extremely expensive. The
impact on the year's earnings was approximately $.13 per diluted
share, with most of that landing in the fourth quarter. We believe
that approximately 60% to 70% of these start up costs will not be
required in future years as we maintain the ongoing program. Despite
this overwhelming cost, it is a tribute to our Company as a whole, and
to our dedicated employees in particular, to have completed the
process so efficiently, successfully and without any material
weaknesses.
    Mr. Brown continued: "Throughout the year we also continued to
generate positive leads in our acquisition program. We will continue
to pursue these and other leads and actively attempt to acquire
laboratories which enhance our reputation as the leading operator of
high quality dental laboratories in the United States. Our two most
recent acquisitions of D. H. Baker Dental Laboratory and Wornson -
Polzin Dental Laboratory, in addition to adding over $7 million of
annualized revenues, typify and augment National Dentex's reputation
for quality driven and customer focused dental laboratories."
    National Dentex Corporation serves an active customer base of over
20,000 dentists through dental laboratories located in 29 states.
National Dentex's dental laboratories provide a full range of
custom-made dental prosthetic appliances, including dentures, crowns
and fixed bridges, and other dental specialties.
