<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:center;margin:0pt;"><b>NATIONAL PRESTO INDUSTRIES, INC. ANNOUNCES</b></p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:center;margin:0pt;"><b>INCREASED FIRST QUARTER 2025 SALES AND EARNINGS</b></p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">Eau Claire, Wisconsin (May 2, 2025) &#8212; National Presto Industries, Inc. (NYSE: NPK) announced today first quarter 2025 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.</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">In response to questions about sales and earnings for the quarter, Maryjo Cohen, President, stated, &#8220;All three segments enjoyed increased sales during first quarter 2025 from those reported in 2024. Defense segment sales were up sizably&#8212;$25.9 million or 47.1%, reflecting increased shipments from its backlog, while the sales at the Small Appliance/Housewares and Safety segments were up nominally. The Defense segment&#8217;s operating earnings were up $4.9 million or 58.6%, primarily attributable to the increased shipments. In contrast, the Housewares/Small Appliance segment reported an operating loss chiefly due to a less favorable mix and higher material costs. The Trump tariffs that went into the effect on goods deemed to have been shipped from the Orient after January 31 also unfavorably affected earnings. Those tariffs are treated as period costs at the time they are incurred. With the President&#8217;s so-called &#8220;Liberation Day&#8221; proclamation, the Trump tariffs are now at 145%. As a result, the announcement (normally included in the first quarter release) of new products and their purchase have been placed on hold. The Safety segment reported a loss as anticipated. Due to the sizable investment in inventory required to support augmented Defense segment awards, the quarter&#8217;s portfolio earnings were nominal.&#8221;</p>

<p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&nbsp;</p>

<p style="font-family:Times New Roman;font-size:10pt;font-variant:normal;text-align:justify;margin:0pt;">National Presto Industries, Inc. operates in three business segments. The Housewares/Small Appliance segment designs and sells small household appliances and pressure cookers under the PRESTO&#174; brand name. The segment is recognized as an innovator of new products. The Defense segment manufactures a variety of products, including medium caliber training and tactical ammunition, energetic ordnance items, fuzes, cartridge cases, and metal parts. The Safety segment offers smoke and carbon monoxide alarms and systems that provide early warning of conditions that, if not corrected, would cause significant losses.</p>
