TO: Participants in the Nordson Employees’ Savings Trust Plan (NEST)

As a participant in the NEST, which includes the Nordson Stock Fund, Nordson Match Stock Fund, and the Nordson ESOP Stock Fund that you may be enrolled in, you are a shareholder of Nordson Corporation and are entitled to vote on matters brought before the shareholders during Nordson Corporation’s February 28, 2023 Annual Meeting of Shareholders. You may cast your vote by proxy by following the instructions on how to vote by internet, telephone or mail provided with the Voting Instruction Form and Proxy Card.

Your vote is important, because when you vote, you are not only voting the Nordson shares allocated to your account. As a participant, you are also voting a pro rata portion of (a) those shares which have not yet been allocated to participant accounts and (b) those shares allocated to participant accounts for which the Trustee, John Hancock, does not receive voting instructions.

I encourage you to read the Notice of 2023 Annual Meeting and Proxy Statement before voting. If you have not received the Notice and Proxy Statement or an Annual Report to Shareholders, please contact Corporate Communications at (440) 414-5606.

Sincerely,

Shelly M. Peet

Executive Vice President
