Ladies and Gentlemen:

Nordson Corporation, an Ohio corporation (the “Company”), proposes to issue and sell to the several Underwriters listed in Schedule 1 hereto (the “Underwriters”), for whom you are acting as representatives (the “Representatives”), $600,000,000 principal amount of its 4.500% Notes due 2029 (the “Securities”). The Securities will be issued pursuant to the Indenture, dated as of September 13, 2023 (the “Base Indenture”), between the Company and U.S. Bank Trust Company, National Association, as trustee (the “Trustee”), as amended by a Second Supplemental Indenture to be dated as of September 9, 2024 (the “Second Supplemental Indenture” and, together with the Base Indenture, the “Indenture”).

The Company hereby confirms its agreement with the several Underwriters concerning the purchase and sale of the Securities, as follows:

1. Registration Statement. The Company has prepared and filed with the U.S. Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Securities Act”), a registration statement on Form S-3 (File No. 333-274340), including a prospectus, relating to the Securities. Such registration statement, as amended at the time it became effective, including the information, if any, deemed pursuant to Rule 430A, 430B or 430C under the Securities Act to be part of the registration statement at the time of its effectiveness (“Rule 430 Information”), is referred to herein as the “Registration Statement”; and as used herein, the term “Preliminary Prospectus” means each prospectus included in such registration statement (and any amendments thereto) before effectiveness, any prospectus filed with the Commission pursuant to Rule 424(a) under the Securities Act and the prospectus included in the Registration Statement at the time of its effectiveness that omits Rule 430 Information, and the term “Prospectus” means the prospectus in the form first used (or made available upon request of purchasers pursuant to Rule 173 under the Securities Act) in connection with confirmation of sales of the Securities. Any reference in this agreement (this “Agreement”) to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the Securities Act, as of the effective date of the Registration Statement or the date of such Preliminary Prospectus or the Prospectus, as the case may be, and any reference to “amend,” “amendment” or “supplement” with respect to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include any documents filed by the Company after such date under the Securities Exchange Act of 1934, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Exchange Act”) that are deemed to be incorporated by reference therein. Capitalized terms used but not defined herein shall have the meanings given to such terms in the Registration Statement and the Prospectus.

At or prior to 4:20 P.M., New York City time, on September 4, 2024, the time when sales of the Securities were first made (the “Time of Sale”), the Company had prepared the following information (collectively, the “Time of Sale Information”): a Preliminary Prospectus dated September 4, 2024, and the “free-writing prospectus” (as defined pursuant to Rule 405 under the Securities Act) listed on Annex A hereto.

On August 21, 2024, through the merger of its wholly-owned subsidiary Alpha Medical Merger Sub, Inc. (“Merger Sub”) with and into Atrion Corporation, a Delaware corporation (“Atrion”), with Atrion surviving as a wholly-owned subsidiary of the Company, the Company completed the acquisition of Atrion and its direct and indirect subsidiaries and all issued and outstanding shares of common stock of Atrion (other than shares (i) held in the treasury of Atrion or owned by any direct or indirect wholly-owned subsidiary of Atrion, (ii) owned by Merger Sub, the Company or any of its direct or indirect wholly-owned subsidiaries or (iii) subject to appraisal) were cancelled for aggregate merger consideration of approximately $810 million (collectively, the “Acquisition”). The Company financed the Acquisition through a combination of borrowings under its existing revolving credit facility and the proceeds of a $500 million committed senior unsecured 364-Day term loan facility (the “364-Day Term Loan”).

The Company intends to use the proceeds of the offering of the Securities to repay in full the amounts borrowed under the 364-Day Term Loan, to pay related fees and expenses and for general corporate purposes.

(a) The Company agrees to issue and sell the Securities to the several Underwriters as provided in this Agreement, and each Underwriter, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, agrees, severally and not jointly, to purchase from the Company, at a price equal to 99.207% of the principal amount thereof plus accrued interest, if any, from September 9, 2024 to the Closing Date (as defined below), the respective principal amount of Securities set forth opposite such Underwriter’s name in Schedule 1 hereto. The Company will not be obligated to deliver any of the Securities except upon payment for all the Securities to be purchased as provided herein.

The Company acknowledges and agrees that the Underwriters may offer and sell Securities to or through any affiliate of an Underwriter and that any such affiliate may offer and sell Securities purchased by it to or through any Underwriter.

(c) Payment for and delivery of the Securities will be made at the offices of Simpson Thacher & Bartlett LLP, 425 Lexington Avenue, New York, New York 10017 at 10:00 A.M., New York City time, on September 9, 2024, or at such other time or place on the same or such other date, not later than the fifth business day thereafter, as the Representatives and the Company may agree upon in writing.

The Global Note will be made available for inspection by the Representatives not later than the day prior to the Closing Date.

(e) The Company acknowledges and agrees that each Underwriter is acting solely in the capacity of an arm’s length contractual counterparty to the Company with respect to the offering of Securities contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, the Company or any other person. Additionally, neither the Representatives nor any other Underwriter is advising the Company or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Company shall consult with its own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and the Underwriters shall have no responsibility or liability to the Company with respect thereto. Any review by the Representatives or any Underwriter of the Company, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Representatives or such Underwriter, as the case may be, and shall not be on behalf of the Company or any other person.

untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Time of Sale Information, it being understood and agreed that the only such information consists of the following paragraphs in the Preliminary Prospectus and the Prospectus: the first sentence of the third paragraph, the third sentence of the sixth paragraph, the seventh paragraph and the eighth paragraph, each under the caption “Underwriting (Conflicts of Interest).”

(c) Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under paragraph (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under paragraph (a) or (b) above. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 7 that the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses of such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be paid or reimbursed as they are incurred. Any such separate firm for any Underwriter, its affiliates, directors and officers and any control persons of such Underwriter shall be designated in writing by the Representatives and any such separate firm for the Company, its directors and officers who signed the Registration Statement and any control persons of the Company shall be designated in writing by the Company.

23

The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d) Contribution. If the indemnification provided for in paragraph (a) or (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company from the sale of the Securities and the total underwriting discounts and commissions received by the Underwriters in connection therewith, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate offering price of the Securities. The relative fault of the Company on the one hand and the Underwriters on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) Limitation on Liability. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 7, in no

24

event shall an Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Securities exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 7 are several in proportion to their respective purchase obligations hereunder and not joint.

(f) Non-Exclusive Remedies. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any Indemnified Person at law or in equity.

8. Effectiveness of Agreement. This Agreement shall become effective as of the date first written above.

9. Termination. This Agreement may be terminated in the absolute discretion of the Representatives, by notice to the Company, if after the execution and delivery of this Agreement and on or prior to the Closing Date (i) trading generally shall have been suspended or materially limited on the New York Stock Exchange or the over-the-counter market; (ii) trading of any securities issued or guaranteed by the Company shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities; or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the judgment of the Representatives, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Prospectus.

10. Defaulting Underwriter.

(a) If, on the Closing Date, any Underwriter defaults on its obligation to purchase the Securities that it has agreed to purchase hereunder, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Company on the terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Securities on such terms. If other persons become obligated or agree to purchase the Securities of a defaulting Underwriter, either the non-defaulting Underwriters or the Company may postpone the Closing Date for up to five full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Underwriters may be necessary in the Registration Statement, the Time of Sale Information and the Prospectus or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Registration Statement,

25

the Time of Sale Information and the Prospectus that effects any such changes. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 10, purchases Securities that a defaulting Underwriter agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Securities, then the Company shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Securities that such Underwriter agreed to purchase hereunder plus such Underwriter’s pro rata share (based on the principal amount of Securities that such Underwriter agreed to purchase hereunder) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made.

(c) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate principal amount of such Securities that remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Securities, or if the Company shall not exercise the right described in paragraph (b) above, then this Agreement shall terminate without liability on the part of the non-defaulting Underwriters. Any termination of this Agreement pursuant to this Section 10 shall be without liability on the part of the Company, except that the Company will continue to be liable for the payment of expenses as set forth in Section 11(a) hereof and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect.

(d) Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company or any non-defaulting Underwriter for damages caused by its default.

11. Payment of Expenses.

(a) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Company agrees to pay or cause to be paid all costs and expenses incident to the performance of its obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Securities and any taxes payable in that connection; (ii) the costs incident to the preparation, printing and filing under the Securities Act of the Registration Statement, the Preliminary Prospectus, any Issuer Free Writing Prospectus, any Time of Sale Information and the Prospectus (including all exhibits, amendments and supplements thereto) and the distribution thereof; (iii) the costs of reproducing and distributing each of the Transaction Documents; (iv) the fees and expenses of the Company’s counsel and independent accountants; (v) the fees and expenses incurred in connection with the registration or qualification and determination of eligibility for investment of the Securities under the laws of such jurisdictions as the Representatives

26

may designate and the preparation, printing and distribution of a Blue Sky Memorandum (including the related fees and expenses of counsel for the Underwriters in an amount not to exceed $20,000); (vi) any fees charged by rating agencies for rating the Securities; (vii) the fees and expenses of the Trustee and any paying agent (including related fees and expenses of any counsel to such parties); (viii) all expenses and application fees incurred in connection with any filing with, and clearance of the offering by, the Financial Industry Regulatory Authority, and the approval of the Securities for book-entry transfer by DTC; and (ix) all expenses incurred by the Company in connection with any “road show” presentation to potential investors.

(b) If (i) this Agreement is terminated pursuant to Section 9, (ii) the Company for any reason fails to tender the Securities for delivery to the Underwriters (other than pursuant to Section 10) or (iii) the Underwriters decline to purchase the Securities for any reason permitted under this Agreement (other than pursuant to Section 10), the Company agrees to reimburse the Underwriters (other than a defaulting Underwriter) for all out-of-pocket costs and expenses (including the fees and expenses of their counsel) reasonably incurred by the Underwriters in connection with this Agreement and the offering contemplated hereby.

12. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and any controlling persons referred to herein, and the affiliates of each Underwriter referred to in Section 7 hereof. Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Securities from any Underwriter shall be deemed to be a successor merely by reason of such purchase.

13. Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of the Company and the Underwriters contained in this Agreement or made by or on behalf of the Company or the Underwriters pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Securities and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of the Company or the Underwriters.

14. Certain Defined Terms. For purposes of this Agreement, (a) except where otherwise expressly provided, the term “affiliate” has the meaning set forth in Rule 405 under the Securities Act; (b) the term “business day” means any day other than a day on which banks are permitted or required to be closed in New York City; (c) the term “subsidiary” has the meaning set forth in Rule 405 under the Securities Act; and (d) the term “significant subsidiary” has the meaning set forth in Rule 1-02 of Regulation S-X under the Exchange Act.

27

L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Company, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

SECOND SUPPLEMENTAL INDENTURE, dated as of September 9, 2024 (this “Supplemental Indenture”), between NORDSON CORPORATION, an Ohio corporation (the “Company”), and U.S. BANK TRUST COMPANY, NATIONAL ASSOCIATION, as trustee (the “Trustee”), to the Indenture, dated as of September 13, 2023, as amended and supplemented through the date of this Supplemental Indenture (the “Indenture”).

WHEREAS, the Company and the Trustee executed and delivered the Indenture substantially in the form of Indenture previously filed as Exhibit 4.1 to the Registration Statement (No. 333-274340) filed with the Securities and Exchange Commission (the “Commission”) on Form S-3 by the Company;

WHEREAS, the Company desires to create a new series of Securities to be issued under the Indenture, as hereby supplemented, consisting of $600.0 million in an initial aggregate principal amount of Securities to be designated the “4.500% Notes due 2029” (hereinafter, the “Notes”), the form and substance of such Notes and the terms, provisions and conditions thereof to be set forth as provided in the Indenture and this Supplemental Indenture;

WHEREAS, Section 9.1(i) of the Indenture provides that the Company and the Trustee may amend or supplement the Indenture without the written consent of the Holders of the outstanding Securities to provide for the issuance of and establish the form and terms and conditions of Securities of any Series as permitted by the Indenture;

WHEREAS, all acts and things prescribed by the Indenture, by law and by the organizational documents of the Company and the Trustee necessary to make this Supplemental Indenture a valid instrument legally binding on the Company and the Trustee, in accordance with its terms, have been duly done and performed; and

WHEREAS, all conditions precedent to amend or supplement the Indenture have been met.

NOW, THEREFORE, to comply with the provisions of the Indenture, and in consideration of the above premises, the Company and the Trustee covenant and agree as follows:

ARTICLE 1

Section 1.01 Nature of Supplemental Indenture. This Supplemental Indenture supplements the Indenture and does and shall be deemed to form a part of, and shall be construed in connection with and as part of, the Indenture for any and all purposes.

Section 1.02 Establishment of New Series. Pursuant to Section 2.2 of the Indenture, there is hereby established a series of Notes having the terms, in addition to those set forth in the Indenture and this Supplemental Indenture, set forth in the form of Note, attached to this Supplemental Indenture as Exhibit A, which are incorporated herein as a part of this Supplemental Indenture. In addition to the initial aggregate principal amount of the Notes issued on the date hereof, the Company may issue additional Notes under the Indenture and this Supplemental Indenture in accordance with Section 2.2 of the Indenture.

Section 1.03 Optional Redemption. (a) Prior to November 15, 2029 (one month prior to their maturity date) (the “Par Call Date”), the Company may redeem the Notes at its option, at any time in whole or from time to time in part, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

(i) 100% of the principal amount of the Notes to be redeemed; and

(ii) (a) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed, in each case, discounted to the redemption date (assuming the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 15 basis points, less (b) interest accrued thereon to the date of redemption,

plus, in either case for clause (i) or (ii) above, accrued and unpaid interest thereon to, but not including, the redemption date.

(b) At any time on or after the Par Call Date, the Notes shall be redeemable as a whole or in part, at any time from time to time, at the Company’s option, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed plus accrued and unpaid interest on the Notes to be redeemed to, but not including, the date of redemption

(c) The Company’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.

(d) The calculation or determination of the redemption price shall be made by the Company or on its behalf by such person as the Company shall designate. For the avoidance of doubt, the calculation or determination of the redemption price shall not be the obligation or responsibility of the Trustee or Paying Agent.

(e) Unless the Company defaults in the payment of the redemption price, interest will cease to accrue on any Notes that have been called for redemption at the redemption rate.

ARTICLE 2

Section 2.01 For all purposes of this Supplemental Indenture, except as otherwise expressly provided or unless the context requires otherwise:

(a) A term defined in the Indenture and not otherwise defined herein has the same meaning when used in this Supplemental Indenture; and

2

(b) The following terms have the meanings given to them in this Section 2.01 and shall have the meaning set forth below for the purposes of this Supplemental Indenture and the Indenture solely with respect to the Notes:

“Applicable Procedures” means, with respect to any transfer or exchange of or for beneficial interests in any Global Note, the rules and procedures of the Depositary, Euroclear and Clearstream that apply to such transfer or exchange at the relevant time.

“Attributable Debt” with respect to a Sale and Leaseback Transaction with respect to any Principal Property, the lesser of: (a) the fair market value of such property (as determined by the Company’s Board of Directors in good faith); or (b) the present value of the total net amount of rent required to be paid under such lease during the remaining term thereof (including any period for which such lease has been extended and excluding any unexercised renewal or other extension options exercisable by the lessee, and excluding amounts on account of maintenance and repairs, services, taxes and similar charges and contingent rents), discounted at the rate of interest set forth or implicit in the terms of such lease (or, if not practicable to determine such rate, the weighted average interest rate per annum borne by the notes) compounded semi-annually. In the case of any lease which is terminable by the lessee upon the payment of a penalty, such net amount will be the lesser of the net amount determined assuming termination upon the first date such lease may be terminated (in which case the net amount will also include the amount of the penalty, but no rent will be considered as required to be paid under such lease subsequent to the first date upon which it may be so terminated) or the net amount determined assuming no such termination.

“Capital Lease” means any lease of any Principal Property that is or should be accounted for as a capital lease on the consolidated balance sheet of the Company and the Company’s Subsidiaries prepared in accordance with GAAP.

“Capital Stock” means and includes any and all shares, interests, participations or other equivalents (however designated) of ownership in a corporation or other Person.

“Certificated Note” means a certificated Note registered in the name of the Holder thereof and issued in accordance with Section 4.01 of this Supplemental Indenture, in the form of Exhibit A to this Supplemental Indenture, except that such Certificated Note shall not include the information called for by the footnotes included therein.

“Change of Control” means the occurrence of any of the following:

(a) the direct or indirect sale, lease, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or more series of related transactions, of all or substantially all of the Company’s assets and its Subsidiaries’ assets, taken as a whole, to any person, other than the Company or one of the Company’s Subsidiaries; provided, however, that none of the circumstances in this clause (a) will be a Change of Control if the persons that beneficially own the Company’s Voting Stock immediately prior to the transaction own, directly or indirectly, shares with a majority of the total voting power of all outstanding voting securities of the surviving or transferee person that are entitled to vote generally in the election of that person’s board of directors, managers or trustees immediately after the transaction;

3

(b) the consummation of any transaction (including, without limitation, any merger or consolidation), the result of which is that any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) becomes the “beneficial owner” (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of the Company’s outstanding Voting Stock or other Voting Stock into which the Company’s Voting Stock is reclassified, consolidated, exchanged or changed, measured by voting power rather than number of shares; provided, however, that a person shall not be deemed a beneficial owner of, or to own beneficially, (i) any securities tendered pursuant to a tender or exchange offer made by or on behalf of such person or any of such person’s affiliates until such tendered securities are accepted for purchase or exchange thereunder, or (ii) any securities if such beneficial ownership (x) arises solely as a result of a revocable proxy delivered in response to a proxy or consent solicitation made pursuant to the applicable rules and regulations under the Exchange Act, and (y) is not also then reportable on Schedule 13D (or any successor schedule) under the Exchange Act;

(c) the Company consolidates with, or merges with or into, any person, or any person consolidates with, or merges with or into, the Company, in any such event pursuant to a transaction in which any of the Company’s outstanding Voting Stock or the Voting Stock of such other person is converted into or exchanged for cash, securities or other property, other than any such transaction where the shares of the Company’s Voting Stock outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, a majority of the Voting Stock of the surviving person or any direct or indirect parent company of the surviving person immediately after giving effect to such transaction; or

At such time as all beneficial interests in a particular Global Note have been exchanged for Certificated Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global Note shall be returned to or retained and canceled by the Trustee in accordance with Section 2.12 of the Indenture. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a person who will take delivery thereof in the form of a beneficial interest in another Global Note or for Certificated Notes, the principal amount of Notes represented by such Global Note shall be reduced accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a person who shall take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note shall be increased accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee to reflect such increase.

Nordson Corporation, an Ohio corporation (hereinafter called the “Company,” which term includes any successors under the Indenture hereinafter referred to), promises to pay interest on the principal amount of this Security at the rate of 4.500% per annum from September 9, 2024 or the most recently occurred Interest Payment Date from the date of issuance of additional Securities, until maturity. To the extent it is lawful, the Company promises to pay interest on any interest payment due on such principal amount but unpaid at a rate of 4.500% per annum compounded semi-annually.

The Company will pay interest semi-annually in arrears on June 15 and December 15 of each year (each, an “Interest Payment Date”), commencing December 15, 2024. Interest on the Securities will accrue from the most recent date to which interest has been paid or, if no interest has been paid on the Securities, from the date of the original issuance. Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months.

The Company shall pay interest on the Securities (except defaulted interest) to the persons who are the registered Holders at the close of business on the Record Date on the next preceding Interest Payment Date. Holders must surrender Securities to a Paying Agent to collect principal payments. Principal of, premium, if any, and interest on the Securities will be payable in United States Dollars at the office or agency of the Company maintained for such purpose, in the contiguous United States or at the option of the Company, payment of interest may be made by check mailed to the Holders of the Securities at the addresses set forth upon the registry books of the Company; provided, however, Holders of Global Notes will be entitled to receive interest payments (other than at maturity) by wire transfer of immediately available funds, if appropriate wire transfer instructions have been received in writing by the Trustee not fewer than 15 days prior to the applicable Interest Payment Date. Such wire instructions, upon receipt by the Trustee, shall remain in effect until revoked by such Holder. No service charge will be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.11, 3.6 and 9.6 of the Indenture).

Initially, U.S. Bank Trust Company, National Association will act as Paying Agent and Registrar. The Company may change any Paying Agent, Registrar or co-Registrar without notice to the Holders. The Company or any of its Subsidiaries may, subject to certain exceptions, act as Paying Agent, Registrar or co-Registrar.

The Company issued the Securities under an Indenture, dated as of September 13, 2023, as supplemented (the “Indenture”), between the Company and the Trustee. Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein. The Securities are unlimited in aggregate principal amount. The terms of the Securities include those stated in the Indenture

A-5

and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as in effect on the date of the Indenture. The Securities are subject to all such terms, and Holders of the Securities are referred to the Indenture and said Act for a statement of them. To the extent any provision of the Securities conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Securities are senior, general obligations of the Company. Each Holder of this Security, by accepting the same, (a) agrees to and shall be bound by the provisions of the Indenture, (b) authorizes and directs the Trustee on his behalf to take such action as may be provided in the Indenture and (c) appoints the Trustee as his attorney-in-fact for such purpose.

(a) Prior to November 15, 2029 (one month prior to their maturity date) (the “Par Call Date”), the Company may redeem the Securities at its option, at any time in whole or from time to time in part, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

(i) 100% of the principal amount of the Securities to be redeemed; and

(ii) (a) the sum of the present values of the remaining scheduled payments of principal and interest on the Securities to be redeemed, in each case discounted to the redemption date (assuming the Securities matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 15 basis points, less (b) interest accrued thereon to the date of redemption,

plus, in either clause (i) or (ii) above, accrued and unpaid interest thereon to, but not including, the redemption date.

(b) The Securities shall be redeemable, at the option of the Company, at any time on or after the Par Call Date, in whole or in part, at any time from time to time, at a redemption price equal to 100% of the principal amount of the Securities to be redeemed plus accrued and unpaid interest on the Securities to be redeemed to, but not including, the date of redemption.

(c) In each of paragraphs (a) and (b) of this Section 5, the Company shall pay accrued and unpaid interest on the principal amount being redeemed to the date of redemption.

The Securities are in registered form, without coupons, in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. A Holder may register the transfer of, or exchange Securities in accordance with, the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture.

The registered Holder of a Security may be treated as the owner of it for all purposes.

A-6

Subject to applicable abandoned property law, if money for the payment of principal or interest remains unclaimed for two years, the Trustee and the Paying Agent(s) will pay the money back to the Company at its written request. After that, all liability of the Trustee and such Paying Agent(s) with respect to such money shall cease.

Except as set forth in the Indenture, the Company shall have irrevocably deposited or caused to be deposited with the Trustee as trust funds specifically pledged as security for and dedicated solely to the benefit of the Holders of such Securities (i) in the case of Securities denominated in Dollars, cash in Dollars and/or U.S. Government Obligations or (ii) in the case of Securities denominated in a Foreign Currency (other than composite currency), money and/or Foreign Government Obligations, which through the payment of interest and principal in respect thereof in accordance with their terms, will provide (and without reinvestment and assuming no tax liability will be imposed on such Trustee), not later than one day before the due date of any payment of money, an amount in cash, sufficient, in the opinion of a nationally recognized firm of independent public accountants or investment bank expressed in a written certification thereof delivered to the Trustee, to pay and discharge each installment of principal and interest, on and any mandatory sinking fund payments in respect of all the Securities on the dates such installments of principal or interest and such sinking fund payments are due, the Company may defease, or be discharged from, as the case may be, certain provisions of the Indenture and the Securities (as specified in the Indenture and the Supplemental Indenture, but in each case excluding its obligation to pay the principal of, premium, if any, and interest on the Securities). Upon satisfaction of certain additional conditions set forth in the Indenture, the Company may elect to have its obligations and the obligations of any Subsidiary that becomes a guarantor, if applicable, discharged with respect to outstanding Securities.

The Company, any Subsidiary that becomes a guarantor, if applicable, and the Trustee may enter into a supplemental indenture for certain limited purposes without the consent of the Holders. Subject to certain exceptions, the Indenture or the Securities may be amended or supplemented with the written consent of the Holders of not less than a majority in aggregate principal amount of the Securities then outstanding, and any existing Default or Event of Default or compliance with any provision may be waived with the consent of the Holders of a majority in aggregate principal amount of the Securities then outstanding. Without notice to or consent of any Holder, the parties thereto may under certain circumstances amend or supplement the Indenture or the Securities to, among other things, cure any ambiguity, defect or inconsistency, or make any other change that does not adversely affect the rights of any Holder of a Security.

The Indenture imposes certain limitations on the ability of the Company and any Subsidiary to, among other things, incur Liens, enter into Sale and Leaseback Transactions, merge or consolidate with any other person or transfer (by lease, assignment or otherwise) substantially all of the properties and assets of the Company. The limitations are subject to a number of important qualifications and exceptions. The Company must periodically report to the Trustee on compliance with such limitations.

A-7

When a successor assumes all the obligations of its predecessor under the Securities and the Indenture, the predecessor will be released from those obligations.

If an Event of Default with respect to the Securities occurs and is continuing (other than an Event of Default relating to bankruptcy, insolvency or reorganization of the Company), then either the Trustee or the Holders of 25% in aggregate principal amount of the Securities then outstanding may declare all Securities to be due and payable immediately in the manner and with the effect provided in the Indenture. Holders of the Securities may not enforce the Indenture or the Securities, except as provided in the Indenture. The Trustee may require indemnity or security satisfactory to it before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Securities may direct the Trustee in its exercise of any trust or power with respect to such Securities. The Trustee may withhold from Holders of the Securities notice of any continuing Default or Event of Default (except a Default in payment of principal or interest) if it determines that withholding notice is in their interest.

The Trustee and each Agent under the Indenture, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or any Subsidiary that becomes a guarantor of the Securities, if applicable, or any of their Subsidiaries or any of their respective Affiliates, and may otherwise deal with such persons as if it were not the Trustee or such agent.

No recourse for the payment of the principal of, premium, if any, or interest on the Securities or for any claim based thereon or otherwise in respect thereof, and no recourse under or upon any obligation, covenant or agreement of the Company or any Subsidiary that becomes a guarantor of the Securities, if applicable, in the Indenture, or in the Securities or because of the creation of any indebtedness represented thereby, shall be had against any past, present or future directors, officers, employees or securityholders of the Company or any Subsidiary that becomes a guarantor of the Securities, if applicable, or of any successor person thereof, except as an obligor or guarantor of the Securities pursuant to the Indenture. Each Holder, by accepting the Securities, waives and releases all such liability.

This Security shall not be valid until the Trustee or authenticating agent manually signs the certificate of authentication on the other side of this Security.

Nordson Corporation

28601 Clemens Road

Westlake, Ohio 44145

Ladies and Gentlemen:

We have acted as counsel to Nordson Corporation, an Ohio corporation (the “Company”), and are rendering this opinion in connection with the prospectus, dated September 5, 2023 (the “Base Prospectus”), as supplemented by the preliminary prospectus supplement, dated September 4, 2024 (the “Preliminary Prospectus Supplement”), and the final prospectus supplement, dated September 4, 2024 (the “Final Prospectus Supplement” and, together with the Base Prospectus and the Preliminary Prospectus Supplement, the “Prospectus”), relating to the registration statement on Form S-3 (the “Registration Statement”) filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Act”), on September 5, 2023 and the offer and sale of $600,000,000 of the Company’s 4.500% Notes due 2029 (the “Notes”) to be issued pursuant to the Indenture, dated as of September 13, 2023 (the “Base Indenture”), between the Company and U.S. Bank Trust Company, National Association, as trustee (the “Trustee”), as supplemented by the Second Supplemental Indenture, dated as of September 9, 2024 (the “Supplemental Indenture”), between the Company and the Trustee (the Base Indenture, as supplemented by the Supplemental Indenture, the “Indenture”).

In connection with this opinion, we have examined such corporate records, certificates and other documents, and such questions of law, as we have considered necessary or appropriate for the purposes of this opinion. We have assumed that all signatures are genuine, that all documents submitted to us as originals are authentic and that all copies of documents submitted to us conform to the originals.

We have relied as to certain matters on information furnished by public officials, officers of the Company, and other sources believed by us to be responsible.

Based upon and subject to the foregoing and subject also to the limitations, qualifications, exceptions and assumptions set forth herein, we are of the opinion that:

(1) the Company (i) is a corporation incorporated, validly existing and in good standing under the laws of the State of Ohio, (ii) possesses the corporate power and authority to execute and deliver the Indenture and to perform its obligations thereunder, and (iii) has duly authorized, executed and delivered the Indenture.

(2) as of the date hereof, the Notes constitute valid and legally binding obligations of the Company, enforceable against the Company in accordance with their terms.

Our opinion in paragraph (2) expressed above is subject to (a) applicable bankruptcy, insolvency (including, without limitation, all laws relating to fraudulent transfer or conveyance), reorganization, moratorium and other similar laws affecting creditors’ rights generally, (b) general principles of equity (regardless of whether enforcement is sought in a proceeding in equity or at law), including, without limitation, (i) the possible unavailability of specific performance, injunctive relief or any other equitable remedy and (ii) concepts of materiality, reasonableness, good faith and fair dealing, and we express no opinion herein with respect to provisions relating to severability or separability, and (c) public policy considerations which may limit the rights of parties to obtain remedies.

Our opinion is further subject to (a) the waivers of any usury defense contained in the Indenture which may be unenforceable, (b) requirements that a claim with respect to any Notes denominated in a currency, currency unit or composite currency other than United States Dollars, or a judgment denominated in a currency other than United States Dollars, may be converted into United States Dollars at a rate of exchange prevailing on a date determined pursuant to applicable law, and (c) governmental authority to limit, delay or prohibit the making of payments outside the United States or in foreign currencies, currency units or composite currencies.

We are members of the bar of the State of New York and the State of Ohio. We express no opinion other than as to the federal laws of the United States of America, the laws of the State of New York and the State of Ohio. This opinion is limited to the laws, including the rules and regulations, as in effect on the date hereof, which laws are subject to change with possible retroactive effect.

We hereby consent to the filing of this opinion as Exhibit 5.1 to the Company’s Current Report on Form 8-K to be filed on September 9, 2024. We also hereby consent to the reference to our firm under the heading “Legal Matters” in the Prospectus. In giving this consent, we do not admit that we are “experts” under the Securities Act or the rules and regulations of the Commission thereunder.

This opinion is expressed as of the date hereof, and we disclaim any undertaking to advise you of any subsequent changes of the facts stated or assumed herein or any subsequent changes in applicable law, and we have assumed that at no future time would any such subsequent change of fact or law affect adversely our ability to render at such time an opinion (a) containing the same legal conclusions set forth herein and (b) subject only to such (or fewer) assumptions, limitations and qualifications as are contained herein.
