National Dentex Corporation Announces Fourth Quarter and Full Year 2005 Results

    WAYLAND, Mass.--(BUSINESS WIRE)--March 1, 2006--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, 2005. Sales for the
quarter totaled $34,339,000 compared with $27,599,000 a year earlier,
an increase of 24.4%. Net income for the quarter was $1,344,000 or
$.24 per share on a diluted basis compared to $621,000 or $.11 per
share on a diluted basis in 2004.
    For the full year ended December 31, 2005, sales increased 21.6%
to $135,843,000 compared to $111,753,000 for the same period in 2004.
Net income increased 37.4% to $7,089,000 or $1.27 per share on a
diluted basis from $5,159,000 or $.94 per share on a diluted basis for
the comparable period of 2004.
    Commenting on today's announcements, David Brown, President and
CEO, stated: "We have for several years worked diligently at
positioning National Dentex as a leader in the industry from the
perspective of both our clients and other dental laboratories, through
the Reliance(TM) program and our participation in industry-wide
organizations and initiatives. The results of 2005 show returns along
both fronts of our strategy. Our sales growth of 24.4% for the quarter
and 21.6% for the year included internal sales growth, measured as
sales at dental laboratories owned for both the years ended December
31, 2005 and 2004, of 6.1% for the quarter and 3.7% for the year. On
both a quarterly and an annual basis, these sales growth figures
represent improvements over results obtained over the past several
years. We have worked extremely hard at training our technical team to
respond timely to our clients' needs. We continue to believe that our
future growth depends on maintaining and growing this existing base of
our business by ensuring we meet or exceed the expectations of our
clients."
    Mr. Brown added: "From an acquisition point of view we have aimed
to position National Dentex as a leader in our industry that truly
values its employees and is focused on providing high client service.
As our achievements in these areas are more widely acknowledged in our
industry, we continue to look for business opportunities with
companies that share this commitment to employees and client service.
Our acquisitions in 2005 of Green Dental Laboratories and Wornson
Polzin Dental Laboratory are examples of laboratories that we believe
embrace this commitment, and thereby have helped further strengthen
our industry position in the eyes of clients and other companies."
    Mr. Brown concluded: "While we are happy with the results we
obtained last year, we are not content to rest on our laurels, and
remain committed to exploring ways in which we can build on our
existing platform and further enhance our position as a leader in our
industry."
