              Kadant Reports Record Revenues in First Quarter 2006


ACTON, Mass., May 3, 2006 - Kadant Inc. (NYSE:KAI) reported that revenues from
continuing operations grew 49 percent in the first quarter of 2006, to $75.6
million, compared with $50.7 million in the first quarter of 2005. Excluding a
40 percent revenue increase in the 2006 period from the company's Kadant Johnson
subsidiary and a 3 percent decrease from currency translation, revenues from
continuing operations grew 12 percent. Operating income from continuing
operations in the 2006 quarter was $4.8 million (including $2.1 million from
Kadant Johnson), versus $2.8 million in 2005. Income from continuing operations
(after-tax) was $2.8 million in 2006, or $.20 of diluted earnings per share
(EPS), versus income of $3.1 million, or $.22 of diluted EPS, a year ago.
Earnings in the 2006 period reflect a $.01 impact from stock option expense
rules that have taken effect, and in the 2005 quarter include a $.06 gain due to
a tax reimbursement from our former parent company.

         "We're off to an excellent start in 2006," said William A. Rainville,
chairman and chief executive officer of Kadant. "We saw especially strong demand
for our stock-preparation technologies in China and for our Kadant Johnson
fluid-handling equipment in North America, both of which contributed to record
revenues in the first quarter. We are also very pleased with our first quarter
bookings, which rose 73 percent over the same quarter last year to a record $104
million on the strength of these two product lines. Even without the
contribution of Kadant Johnson, bookings increased 33 percent. This led to a
record quarter-end backlog as well, which nearly doubled from the 2005 first
quarter to $83 million.

         "China's paper-recycling market remains an exciting growth opportunity
for Kadant, and continued demand for our innovative stock-preparation systems
from that country's leading paper producers reinforces that we are clearly a
technology leader. Revenues from these products in China were $9 million in the
first quarter of 2006, a 59 percent increase over last year. Even more
noteworthy, China bookings for stock-preparation systems in the period, which
included the largest single order in our history, totaled $29 million -
exceeding our total annual bookings from China in each of the last two years.

         "In the North American paper industry, although the market for our
accessories and water management product lines remained soft, we believe that
our customers' focus on lowering energy costs is driving demand for our fluid-
handling and control technologies. These systems, which are used primarily to
optimize drying - the most energy-intensive stage of paper production -
contributed $23 million in first quarter 2006 bookings.

         "We believe our strong performance this quarter is further evidence
that our efforts to increase our breadth - of global market coverage and product
offerings - are contributing to growth. With record bookings, we expect a strong
second quarter as well, with GAAP diluted EPS from continuing operations of $.34
to $.36, on revenues of $85 to $87 million. That said, we are still seeing
weakness in some North American and European markets, and therefore remain
cautiously optimistic about the second half of the year. For all of 2006, we now
expect GAAP diluted EPS of $1.18 to $1.25 from continuing operations, an
increase of $.03 at the low end of the range, on slightly higher revenues of
$300 to $310 million, from our original estimate of $290 to $300 million."

Use of Non-GAAP Financial Measures In addition to the financial measures prepared in accordance with generally accepted accounting principles (GAAP), we use certain non-GAAP financial measures, including revenues excluding the results from our Kadant Johnson subsidiary and the effects of currency translation, and earnings before interest, taxes, depreciation and amortization (EBITDA). We believe that the inclusion of such measures helps investors to gain a better understanding of our underlying operations and future prospects, consistent with how management measures and forecasts Kadant's performance, especially when comparing such results to previous periods or forecasts. We also believe this information is responsive to investors' requests and gives them an additional measure of Kadant's performance. We use non-GAAP measures, in addition to GAAP financial measures, as the basis for measuring our underlying operating performance and comparing such performance to that of prior periods or forecasts and to the performance of our competitors. Such measures are also used by us in our financial and operating decision-making and for compensation purposes. The non-GAAP financial measures included in this press release are not meant to be considered superior to or a substitute for the results of operations prepared in accordance with GAAP. In addition, the non-GAAP financial measures included in this press release have limitations associated with their use as compared to the most directly comparable GAAP measure, in that they may be different from, and therefore not comparable to, similar measures used by other companies. Reconciliations of the non-GAAP financial measures to the most directly comparable GAAP financial measures are set forth in the accompanying tables. Conference Call Kadant will hold its earnings conference call on Thursday, May 4, 2006, at 11 a.m. Eastern time. To listen, call 800-709-2159 within the U.S., or 973-582-2810 outside the U.S. You can also listen to the call live on the Web by visiting www.kadant.com and clicking on "Investors."
