Aearo Discloses Results of Operations


INDIANAPOLIS,  January 9, 2004 - Aearo  Corporation,  one of the world's leading
designers,  manufacturers and marketers of a broad range of personal  protective
products,  today  announced that net sales in the year ended  September 30, 2003
increased  10.3% to  $316.4  million  from  $286.9  million  in the  year  ended
September 30, 2002.  The increase in net sales was  primarily  driven by organic
growth  in  the  Safety  Products  segment,   the  impact  of  foreign  currency
translation  and  acquisitions,  partially  offset  by  declines  in the  Safety
Prescription Eyewear and Specialty Composites segments.

EBITDA, defined as earnings before interest, taxes, depreciation,  amortization,
and other non-cash  charges,  increased 11.3% to $54.0 million in the year ended
September 30, 2003 from $48.5 million in the year ended  September 30, 2002. The
increase in EBITDA was primarily driven by organic growth in the Safety Products
segment,  an improvement  in gross margins as a result of ongoing  productivity,
acquisitions and the impact of foreign currency translations.  Gross Profit as a
percentage  of net sales in the year ended  September 30, 2003 improved to 48.2%
as compared to 47.6% in the year ended September 30, 2002.

The Company uses EBITDA, as defined above, a non-GAAP  financial  measure,  as a
management tool to measure and monitor financial  performance and as part of the
calculation of Company  performance as stated in senior bank facility covenants.
While the  Company  believes  EBITDA is a useful  indicator  of its  ability  to
service debt,  EBITDA  should not be  considered as a substitute  for net income
(loss) determined in accordance with accounting principles generally accepted in
the United States of America as an indicator of operating performance,  or as an
alternative  to cash flow as a measure of liquidity.  Investors  should be aware
that EBITDA may not be  comparable  to similarly  titled  measures  presented by
other  companies and  comparisons  could be misleading  unless all companies and
analysts calculate this measure in the same fashion.




The Company  believes that the most  directly  comparable  financial  measure to
EBITDA in accordance with GAAP is income before  provision for income taxes. The
following table provides a  reconciliation  of EBITDA to income before provision
for income taxes for the years ending September 30, 2003 and 2002, respectively:
