NORDSON CORP

The management of Nordson Corporation is responsible for establishing and maintaining adequate internal control over financial reporting.

Using criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO") in Internal Control-Integrated Framework ("2013 framework"), Nordson’s management assessed the effectiveness of our internal control over financial reporting as of October 31, 2024.

We completed the acquisition of Atrion Corporation and its subsidiaries ("Atrion") on August 21, 2024. As permitted by SEC guidance, the scope of our evaluation of internal control over financial reporting as of October 31, 2024 did not include the internal control over financial reporting of Atrion. The results of Atrion are included in our consolidated financial statements from the date the business was acquired. The total assets of the Atrion represented 14% of our total assets at October 31, 2024. The net revenues represented 1% of consolidated revenues for the year ended October 31, 2024 and the net incomefor the year ended October 31, 2024 did not have a material impact on the Company’s operations.

Based on our assessment, management concluded that our internal control over financial reporting was effective as of October 31, 2024.

The independent registered public accounting firm, Ernst & Young LLP, has also audited the effectiveness of our internal control over financial reporting as of October 31, 2024. Ernst & Young LLP's report on Nordson's internal control over financial reporting is included herein.
