                    Kadant Reports 2004 First Quarter Results


ACTON, Mass., April 28, 2004 - For the first quarter of 2004, Kadant Inc.
(NYSE:KAI) reported GAAP diluted earnings per share (EPS) of $.19, compared with
$.22 in the first quarter of 2003. GAAP net income in the 2004 period was $2.7
million, versus $3.0 million a year ago. First quarter revenues were $51.7
million in 2004 (including $3.0 million from the favorable effect of currency
translation), compared with $51.4 million in 2003.

         "We met our EPS guidance for the quarter, although earnings were lower
than last year due primarily to an operating loss of $0.9 million in our
composite building products business, which was within the range we had
forecasted," said William A. Rainville, chairman and chief executive officer of
Kadant. "Revenues, on the other hand, were slightly better than we expected as a
result of strong performance in both of our reporting segments: papermaking
equipment and composite and fiber-based products. Our total order backlog at the
end of the quarter was $42.3 million - a 13 percent increase since the end of
2003.

         "China continues to be a key geographic market for our papermaking
equipment, with the growing need for recycled packaging materials driving sales
of our stock-preparation systems. Revenues and bookings from China were strong
in the first three months, and, after quarter end, we received an order for
nearly $4 million from a major containerboard producer there. We are also
pleased that our emphasis on growing the aftermarket business yielded record
sales in China of spare parts during the quarter. In North America and Europe,
we are seeing sporadic improvement in our markets, as evidenced by increased
sales of our paper machine accessories and water management equipment over the
year-ago quarter.

         "In our composites business, lower production rates as we work off
inventory and higher quarterly warranty expense than last year led to the
operating loss. However, demand for our decking products is increasing, with
quarterly revenues at $4.2 million - near last year's record high - and
quarterly bookings more than double those of last year. We continue to expand
the national network of lumber yards that stock our composite decking systems
and are in the process of adding regional distributors in certain western and
central states. As the year progresses, we expect the warranty claims to decline
and production rates to rise. This, combined with broader distribution of our
products, should return the composites business to profitability in the second
half of the year."

         Mr. Rainville concluded, "For the second quarter of 2004, we expect to
achieve GAAP diluted EPS of $.21 to $.23, on revenues of $55 to $57 million. We
are maintaining our earlier guidance for the full year of $.90 to $1.00 in GAAP
diluted EPS, on revenues of $205 to $215 million."
