CALCULATION OF REGISTRATION FEE

PART I

INFORMATION REQUIRED IN THE SECTION 10(A) PROSPECTUS

EXPLANATORY NOTE

Reincorporation Merger

On May 22, 2020, CONMED Corporation, a New York corporation (the “Predecessor Registrant”), merged with and into CONMED Corporation, a Delaware corporation and wholly-owned subsidiary of CONMED-New York (the “Registrant”), pursuant to an Agreement and Plan of Merger, dated as of May 21, 2020 (the “Merger Agreement”), with the Registrant continuing as the surviving corporation (the “Reincorporation Merger”). The purpose of the Reincorporation Merger was to change the Predecessor Registrant’s state of incorporation from New York to Delaware. The Merger Agreement was approved by the shareholders of the Predecessor Registrant at the annual meeting of shareholders held on May 21, 2020. At the effective time of the Reincorporation Merger (the “Effective Time”), the Registrant succeeded to the assets, continued the business and assumed the rights and obligations of the Predecessor Registrant immediately prior to the Reincorporation Merger all by operation of law. Unless the context otherwise requires, the terms “CONMED Corporation,” “we,” “our,” “the Company” and “us” refer to the Predecessor Registrant with respect to the period prior to the Effective Time and to the Registrant with respect to the period on or after the Effective Time.

At the Effective Time, pursuant to the Merger Agreement:

Pursuant to Rule 12g-3(a) under the Exchange Act, the shares of common stock of the Registrant, as successor issuer, are deemed registered under Section 12(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

In addition, at the Effective Time, the Registrant assumed or succeeded to, by operation of law or otherwise, all of the Predecessor Registrant’s obligations under the following plans or agreements (collectively, the “Plans”):

I-1

As of the Effective Time, all equity-based awards with respect to shares of Predecessor Common Stock granted pursuant to the Plans were converted into corresponding equity-based awards with respect to the same number of shares of Registrant Common Stock, in each case, in accordance with the terms of the applicable Plan and any related award agreement and subject to the same terms and conditions applicable to such awards as were in effect prior to the Reincorporation Merger.

These Post-Effective Amendments (collectively, the “Post-Effective Amendments”) to: with respect to the 1999 LTIP, Registration Statement Nos. 333-78987, 333-90444, 333-124202 and 333-162834; with respect to the 2006 SIP, Registration Statement No. 333-136453; with respect to the A&R LTIP, Registration Statement No. 333-182878; with respect to the 2015 LTIP, Registration Statement No. 333-207582; with respect to the 2018 LTIP, Registration Statement No. 333-228171; with respect to the 2007 NEDP, Registration Statement Nos. 333-145150 and 333-168493; with respect to the 2016 NEDP, Registration Statement No. 333-214299; with respect to the 2002 ESPP, Registration Statement No. 333-90444; and with respect to the Stock Option Inducement Award and Restricted Stock Inducement Award, Registration Statement No. 333-223258 (collectively, the “Registration Statements”) are being filed by the Registrant pursuant to Rule 414 under the Securities Act of 1933, as amended (the “Securities Act”), as the successor issuer to the Predecessor Registrant.

In accordance with Rule 414(d) of the Securities Act, except as modified by these Post-Effective Amendments, the Registrant, as successor issuer to the Precedessor Registrant pursuant to Rule 12g-3 of the Exchange Act, hereby expressly adopts the Registration Statements as its own registration statements for all purposes of the Securities Act and the Exchange Act.

Amendment and Restatement of Plans

Additionally, on December 12, 2019, upon the recommendation of the Compensation Committee of the Registrant’s Board of Directors, the Registrant’s Board of Directors unanimously approved the Amended and Restated 2020 Non-Employee Director Equity Compensation Plan of CONMED Corporation (the “2020 NEDP”), which supercedes the 2016 NEDP, as well as the CONMED Corporation Amended and Restated 2020 Employee Stock Purchase Plan (the “2020 ESPP”), which supercedes the 2002 ESPP, in each case, subject to shareholder approval. The Registrant’s shareholders approved the 2020 NEDP and the 2020 ESPP on May 21, 2020.

Under the terms of the 2020 NEDP, effective as of May 21, 2020, no new grants may be issued under the 2016 NEDP, and the Predecessor Common Stock previously registered and authorized for issuance under the 2016 NEDP will be eligible for issuance under the 2020 NEDP to the extent such Predecessor Common Stock remains available for issuance as of May 21, 2020. As of May 21, 2020, there were 64,609 shares of Predecessor Common Stock previously registered and available for issuance under the 2016 NEDP. Accordingly, pursuant to the undertaking in Item 512(a)(1)(iii) of Regulation S-K that the Registrant disclose a material change in the plan of distribution as it was originally disclosed in the Form S-8 Registration Statement No. 333-214299, filed October 28, 2016 (the “Prior NEDP Registration Statement”), the Registrant is filing this Post-Effective Amendment to the Prior NEDP Registration Statement to reflect that, as of May 21, 2020, the Predecessor Common Stock (as converted to Registrant Common Stock in connection with the Reincorporation Merger) available for issuance under the Prior NEDP Registration Statement as described above will no longer be issued under the 2016 NEDP and may instead become available for issuance under the 2020 NEDP.

I-2

Likewise, the Predecessor Common Stock previously registered and authorized for issuance under the 2002 ESPP will be eligible for issuance under the 2020 ESPP to the extent such Predecessor Common Stock remains available for issuance as of May 21, 2020. As of May 21, 2020, there were 753,367 shares of Predecessor Common Stock previously registered and available for issuance under the 2002 ESPP. Accordingly, pursuant to the undertaking in Item 512(a)(1)(iii) of Regulation S-K that the Registrant disclose a material change in the plan of distribution as it was originally disclosed in the Form S-8 Registration Statement No. 333-90444, filed June 13, 2002 (the “Prior ESPP Registration Statement”), the Registrant is filing this Post-Effective Amendment to the Prior ESPP Registration Statement to reflect that, as of May 21, 2020, the Predecessor Common Stock (as converted to Registrant Common Stock in connection with the Reincorporation Merger) available for issuance under the Prior ESPP Registration Statement as described above will no longer be issued under the 2002 ESPP and may instead become available for issuance under the 2020 ESPP.

As permitted by Rule 428 under the Securities Act, this registration statement omits the information specified in Part I of Form S-8. The documents containing the information specified in Part I will be delivered to the participants in the plans covered by this registration statement as required by Rule 428(b). Such documents are not being filed with the Commission as part of this registration statement or as prospectuses or prospectus supplements pursuant to Rule 424 of the Securities Act.

PART II

INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

The following documents filed by the Registrant pursuant to the Exchange Act (File No. 001-39218), are hereby incorporated by reference in these Post-Effective Amendments:

(a) The annual report on Form 10-K for the fiscal year ended December 31, 2019, filed with the Securities and Exchange Commission (the “Commission”) on February 24, 2020 (the “2019 Form 10-K”).

(b) The quarterly report on Form 10-Q for the fiscal quarter ended March 31, 2020, filed with the Commission on April 30, 2020.

(c) The current reports on Form 8-K, filed with the Commission on January 29, 2020, February  25, 2020, March  16, 2020, March  20, 2020, April  20, 2020 and May 22, 2020.

(d) The description of the Registrant’s Common Stock contained in its Registration Statement on Form 8-A, filed on February  6, 2020 pursuant to the Exchange Act, as amended by Exhibit 4.1 to the Registrant’s current report on Form 8-K filed on May 22, 2020.

All documents filed by the Registrant pursuant to Section 13(a), 13(c), 14 and 15(d) of the Exchange Act (excluding any information furnished under Item 7.01 or Item 2.02 of any Current Report on Form 8-K) after the date of these Post-Effective Amendments and prior to the filing of a post-effective amendment to the applicable Registration Statement which indicates that all securities offered thereby have been sold or which deregisters all securities then remaining unsold, shall be deemed to be incorporated by reference herein and to be a part hereof from the date of filing of such documents.

Any statement contained in a document incorporated or deemed to be incorporated by reference herein shall be deemed to be modified or superseded for purposes of these Post-Effective Amendments to the extent that a statement contained herein (or in any other subsequently filed document which also is incorporated or deemed to be incorporated by reference herein) modifies or supersedes such statement. Any such statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute a part of these Post-Effective Amendments.

Not applicable.

The validity of the Registrant Common Stock registered pursuant to the Registration Statements, as modified by these Post-Effective Amendments, shares of which are issuable by the Registrant pursuant to the Plans, is being passed on by Daniel S. Jonas, Executive Vice President – Legal Affairs, General Counsel & Secretary of the Registrant, who is an executive officer of the Registrant.

Section 145 of the Delaware General Corporation Law (the “DGCL”) provides that a corporation may indemnify any current or former director, officer or employee or other individual against expenses, judgments, fines and amounts paid in settlement in connection with civil, criminal, administrative or investigative actions or proceedings, other than a derivative action by or in the right of the corporation, if the director, officer, employee or other individual acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, if he or she had no reasonable

cause to believe his or her conduct was unlawful. A similar standard is applicable in the case of derivative actions, except that indemnification only extends to expenses incurred in connection with the defense or settlement of such actions, and the statute requires court approval before there can be any indemnification where the person seeking indemnification has been found liable to the corporation. The statute provides that it is not exclusive of other indemnification that may be granted by a corporation’s by-laws, disinterested director vote, stockholder vote, agreement or otherwise.

The Registrant’s certificate of incorporation and by-laws require the indemnification of directors and officers to the fullest extent permitted by law, but the by-laws provide that no indemnification is required with respect to any settlement or disposition of a proceeding unless the Registrant has given its prior consent to such settlement/disposition. The Registrant’s by-laws also permits the Registrant to indemnify employees and to advance expenses to any person entitled to indemnification upon request.

Section 102(b)(7) of the DGCL permits a corporation to provide in its certificate of incorporation that a director of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability for (i) any breach of the director’s duty of loyalty to the corporation or its stockholders, (ii) acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) payments of unlawful dividends or unlawful stock purchases or redemptions, or (iv) any transaction from which the director derived an improper personal benefit. The Registrant’s certificate of incorporation contains a provision eliminating the personal liability of directors for monetary damages to the fullest extent permitted by law.

Not applicable.

(a) The undersigned Registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to the Registration Statements:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the Registration Statements (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statements;

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statements or any material change to such information in the Registration Statements;

provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the Registration Statements.

(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant’s annual report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the Registration Statements shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

Utica, New York 13502-5944

Dear Sirs and Mesdames:

In connection with the filing of Post-Effective Amendments to Registration Statement Nos. 333-78987, 333-90444, 333-124202, 333-136453, 333-145150, 333-162834, 333-168493, 333-182878, 333-207582, 333-214299, 333-223258 and 333-228171 on Form S-8 (collectively, the “Registration Statements”) to be filed on the date hereof by CONMED Corporation, a Delaware corporation (the “Company”), with the Securities and Exchange Commission under the Securities Act of 1933, as amended (the “Securities Act”), I have examined such corporate records, certificates and other documents and such questions of law as I have considered necessary or appropriate for the purposes of this opinion. The Post-Effective Amendments are being filed in connection with the adoption of the Registration Statements by the Company pursuant to Rule 414 under the Securities Act as the successor issuer to CONMED Corporation, a New York corporation. The Registration Statements, as amended by the Post-Effective Amendments, relate to 8,284,218 aggregate shares of the Company’s Common Stock, par value $0.01 per share (the “Shares”), registered and available for issuance or outstanding under the following plans (collectively, the “Plans”): (i) Amended and Restated 1999 Long-Term Incentive Plan; (ii) CONMED Corporation 2006 Stock Incentive Plan; (iii) Amended and Restated Long Term Incentive Plan; (iii) CONMED Corporation Amended and Restated 2015 Long-Term Incentive Plan; (iv) CONMED Corporation 2018 Long-Term Incentive Plan; (v) Amended and Restated 2007 Non-Employee Director Equity Compensation Plan of CONMED Corporation; (vi) Amended and Restated 2016 Non-Employee Director Equity Compensation Plan of CONMED Corporation; (vii) Amended and Restated 2020 Non-Employee Director Equity Compensation Plan of CONMED Corporation; (viii) CONMED Corporation 2002 Employee Stock Purchase Plan, as amended; (ix) CONMED Corporation Amended and Restated 2020 Employee Stock Purchase Plan, (x) January 2, 2018 Stock Option Inducement Award; and (xi) January 2, 2018 Restricted Stock Unit Inducement Award.

Upon the basis of such examination, I advise you that, in my opinion, the Shares have been duly authorized and when the Post-Effective Amendments to the Registration Statements become effective under the Act and the Shares have been duly issued as provided in the Plans, the Shares will be validly issued, fully paid and nonassessable.

The foregoing opinion is limited to the General Corporation Law of the State of Delaware, and I express no opinions with respect to the laws of any other jurisdiction. In rendering the foregoing opinion, I have, with your approval, relied as to certain matters on information obtained from officers of the Company and other sources believed by me to be responsible, and I have assumed that the signatures on all documents examined by me are genuine, assumptions which I have not independently verified.

I hereby consent to the filing of this opinion as an exhibit to the Post-Effective Amendments relating to the Shares. In giving such consent, I do not thereby admit that I am in the category of persons whose consent is required under Section 7 of the Act.

Exhibit 23.2
