NATIONAL PRESTO INDUSTRIES, INC. ANNOUNCES
INCREASED SECOND QUARTER 2006 SALES AND EARNINGS

Eau Claire, Wisconsin (July
28, 2006)  National Presto Industries, Inc. (NYSE: NPK) announced today second quarter sales and earnings, as shown in the
table below. Net earnings per share have been computed on the basis of the weighted average number of common shares outstanding
for the respective periods.

In response to questions
about second quarter 2006 sales and earnings, Maryjo Cohen, President, stated, The 2005 annual report prediction concerning
Defense proved to be as accurate for the second quarter as it had been for first quarter 2006. All three of the Companys
segments enjoyed sales increases during the quarter under review, however, the Defense segments increase had the most
significant impact. Likewise, as in the first quarter, the Defense segment contributed the majority of the quarters earnings
increase, again offset in part by anticipated losses from the Absorbent Product segment. The earnings improvement was further
augmented by an increase in the Housewares/Small Appliance segments earnings over those enjoyed during the prior years
comparable quarter, in largest part attributable to that segments higher sales volume. Increased yields from the
companys portfolio, reflecting the interest rate increases implemented by the Federal Reserve over the past several
quarters, also had a favorable, albeit nominal, impact on earnings.

National Presto manufactures
and sells small household electric appliances and pressure cookers under the PRESTO® brand name. It also produces and sells
medium caliber ammunition items and absorbent products. The Company is widely recognized as an innovator of new products.
