EXPLANATORY NOTE

This Registration Statement on Form S-8 (this “Registration Statement”) is filed by II-VI Incorporated, a Pennsylvania corporation (the “Registrant”), relating to an aggregate of 5,954,044 shares of its common stock, no par value (“II-VI Common Stock”).

On September 24, 2019, in accordance with the terms and conditions of the Agreement and Plan of Merger, dated as of November 8, 2019 (the “Merger Agreement”), by and among the Registrant, Mutation Merger Sub Inc. a Delaware corporation and a wholly owned subsidiary of the Registrant (“Merger Sub”), and Finisar Corporation, a Delaware corporation (“Finisar”), Merger Sub merged with and into Finisar, and Finisar continued as the surviving corporation and a wholly owned subsidiary of the Registrant (the “Merger”). Pursuant to the terms of the Merger Agreement, as of the effective time of the Merger (the “Effective Time”), the Registrant assumed 6,606,702 restricted stock units granted pursuant to the Amended and Restated Finisar Corporation 2005 Stock Incentive Plan (each an “Assumed Finisar RSU”). Each Assumed Finisar RSU is subject to substantially the same terms and conditions as applied to the Assumed Finisar RSU immediately prior to the Effective Time, except that the number of shares of II-VI Common Stock subject to each Assumed Finisar RSU has been adjusted in accordance with the terms of the Merger Agreement. Accordingly, an aggregate of 4,023,481 shares of II-VI Common Stock is issuable in connection with the Assumed Finisar RSUs. Other than the Assumed Finisar RSUs, the Registrant did not assume any other awards outstanding under the Amended and Restated Finisar Corporation 2005 Stock Incentive Plan (the “Finisar 2005 Plan”). In addition, as of the Effective Time, the Registrant assumed (i) the unused capacity under the Finisar 2005 Plan and (ii) the Finisar Corporation 401(k) Profit Sharing Plan (the “Finisar 401(k) Plan”). This Registration Statement also relates to (i) 930,563 shares of II-VI Common Stock issuable in accordance with the terms of the Finisar 2005 Plan and (ii) 1,000,000 shares of II-VI Common Stock issuable pursuant to the Finisar 401(k) Plan.

Substantially concurrently with the filing of this Registration Statement, Finisar will file a post-effective amendment on Form S-8 to deregister all shares of Finisar Common Stock remaining unsold under its Registration Statements on Form S-8 relating to the Finisar 2005 Plan and the Finisar 401(k) Plan, among other compensation plans of Finisar.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

Pennsylvania statutory law regarding directors and officers insurance and indemnification is embodied in Chapter 17, Subchapter D (Sections 1741 through 1750) of the Pennsylvania Business Corporation Law of 1988, as amended (the “PBCL”).

Sections 1741 (relating to third-party actions) and 1742 (relating to derivative and corporate actions) of the PBCL provide that a business corporation may indemnify any director, officer, employee or agent who is or was a representative of, or serving at the request of, the corporation (a “Representative”), so long as the Representative acted in good faith and with a reasonable belief that his or her actions were in the best interests, or not opposed to the best interests, of the corporation, and with respect to any criminal proceeding under Section 1741 of the PBCL, the Representative must have had no reasonable cause to believe his or her conduct was unlawful. In general, the power to indemnify under these sections does not exist in the case of actions against a director or officer by or in the right of the corporation if the person otherwise entitled to indemnification shall have been adjudged to be liable to the corporation unless it is judicially determined that, despite the adjudication of liability but in view of all the circumstances of the case, the person is fairly and reasonably entitled to indemnification for specified expenses.

Section 1743 of the PBCL provides mandatory indemnification for a Representative if he or she succeeds on the merits or otherwise in the defense of any claim or action or proceeding, or in defense of any claim, issue or matter therein. The corporation must indemnify him or her to the extent of his or her actual and reasonable expenses (including attorney’s fees) incurred in connection with the claim or action.

Section 1745 of the PBCL states that expenses (including attorneys’ fees) incurred in defending any third-party or derivative action or proceeding may be paid by a business corporation in advance of the final disposition of the action or proceeding upon receipt of an undertaking by or on behalf of the Representative to repay the amount if it is ultimately determined that such person is not entitled to be indemnified by the corporation as authorized by the PBCL or otherwise. Except as otherwise provided in the corporation’s bylaws, advancement of expenses must be authorized by the board of directors of the corporation and shall not be authorized in connection with proceedings related to transactions with interested directors or officers, or interested shareholders (Sections 1728 and 2538 of the PBCL).

Section 1746(a) states that the statutory rights of indemnification and advancement of expenses shall not be deemed exclusive of any other rights to which a person might be entitled under any bylaw, agreement, vote of shareholders or disinterested directors, or otherwise, both as to the action in his or her official capacity and as to the action or proceeding in another capacity while holding that office. However, Section 1746(b) forbids indemnification to be made in any case where the act or failure to act giving rise to the claim is determined by a court to be willful misconduct or recklessness. A corporation’s articles of incorporation may not provide for indemnification in the case of willful misconduct or recklessness.

The PBCL, in Section 1747, also authorizes corporations to purchase and maintain insurance on behalf of a Representative or a person who is or was serving at the request of the corporation as a representative of another domestic or foreign entity, whether or not the corporation would have the power to indemnify him or her, unless otherwise restricted in its bylaws. Such insurance is declared to be consistent with Pennsylvania’s public policy.

Section 1750 of the PBCL provides that the indemnification and advancement of expenses provided by, or granted pursuant to Subchapter B of the PBCL shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to be a Representative and shall inure to the benefit of the heirs and personal representatives of that person.

Section 6.02 of the Company’s Amended and Restated By-Laws (the “By-Laws”) provides that a director shall not be personally liable for monetary damages for any action taken or failed to be taken unless the director has breached or failed to perform the duties of his or her office (relating to standard of care and justifiable reliance) and such breach or failure to perform constitutes self-dealing, willful misconduct or recklessness. A director’s criminal or tax liability is not limited by the foregoing provision.

Section 6.03 of the By-Laws requires the Company to indemnify any director or officer of the Company, who was or is a party, or is threatened to be made a party, to any action, suit or proceeding (third-party or derivative), arising out of such person’s service to the Company or to another entity at the request of the Company, if the person acted in good faith, in a manner he or she reasonably believed to be in the best interest of the corporation, and with such care, including reasonable inquiry, skill and diligence, as a person of ordinary prudence would use under similar circumstances, and with respect to any criminal action or proceeding, with reasonable cause to believe his or her conduct was lawful. The Company will not indemnify any director of officer in connection with a proceeding initiated by such director or officer (other than a proceeding to enforce such person’s right to indemnification under the By-Laws) unless such proceeding was authorized by the board of directors. The right to indemnification conferred by this provision includes payment of all reasonable expenses (including attorney’s fees), judgments, fines and amounts paid in settlement in connection with such action, suit or proceeding. Section 6.04 of the By-Laws permits the Company to indemnify any employee or agent of the Company who is not a director or officer, with such scope and effect as determined by the Company.

Section 6.06 of the By-Laws permits the Company to purchase and maintain insurance to protect itself and any director, officer, agent or employee against any liability asserted against and incurred by such person in respect of such person’s service, whether or not the Company would have the power to indemnify such person against such liability by law or under the provisions of the By-Laws.

The Company has entered into agreements with its directors and officers pursuant to which the Company has agreed to provide for the indemnification of and the advancing of expenses to each such indemnitee to the fullest extent (whether partial or complete) permitted by law and as set forth in the applicable agreement, and, to the extent insurance is maintained, for the continued coverage of each such indemnitee under the Company’s directors’ and officers’ liability insurance policies. To the fullest extent permissible by applicable law, if the indemnification provided for in each such agreement is unavailable to the applicable indemnitee for any reason whatsoever, the Company, in lieu of indemnifying such indemnitee, shall contribute to the amount incurred such indemnitee, whether for judgments, fines, penalties, excise taxes, amounts paid or to be paid in settlement and/or for expenses, in connection with any claim relating to an indemnifiable event under such agreement, in such proportion as is deemed fair and reasonable in light of all of the circumstances of such claim in order to reflect (i) the relative benefits received by the Company and such indemnitee as a result of the event(s) and/or transaction(s) giving rise to such claim; and/or (ii) the relative fault of the Company (and its directors, officers, employees and agents) and such indemnitee in connection with such event(s) and/or transaction(s).

The indemnification described in the preceding paragraphs may include indemnification against liabilities arising under the Securities Act. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling the Company pursuant to the foregoing provisions, the Company has been informed that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

ITEM 9. UNDERTAKINGS.

(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 this Registration Statement:

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 this Registration Statement (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 Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective Registration Statement.

iii. To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in this Registration Statement;

provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) of this section 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 this Registration Statement.

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 Section 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 this Registration Statement 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.

SIGNATURES

Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this Registration Statement on Form S-8 to be signed on its behalf by the undersigned, thereunto duly authorized, in the Borough of Saxonburg, Commonwealth of Pennsylvania, on this 26th day of September, 2019.

Exhibit 5.1

September 26, 2019

II-VI Incorporated

375 Saxonburg Boulevard

Saxonburg, Pennsylvania 16056

Ladies and Gentlemen:

We have acted as counsel to II-VI Incorporated, a Pennsylvania corporation (the “Company”), in connection with the Registration Statement on Form S-8 (the “Registration Statement”) to be filed by the Company with the Securities and Exchange Commission for the registration under the Securities Act of 1933, as amended (the “Securities Act”), of the offer and sale of an aggregate of 5,954,044 shares of the Company’s common stock, no par value (collectively, the “Shares”).

On September 24, 2019, in accordance with the terms and conditions of the Agreement and Plan of Merger, dated as of November 8, 2019 (the “Merger Agreement”), by and among the Company, Mutation Merger Sub Inc. a Delaware corporation and a wholly owned subsidiary of the Company (“Merger Sub”), and Finisar Corporation, a Delaware corporation (“Finisar”), Merger Sub merged with and into Finisar, and Finisar continued as the surviving corporation and a wholly owned subsidiary of the Company (the “Merger”). Pursuant to the terms of the Merger Agreement, as of the effective time of the Merger (the “Effective Time”), the Company assumed 6,606,702 restricted stock units (each an “Assumed Finisar RSU”) granted pursuant to the Amended and Restated Finisar Corporation 2005 Stock Incentive Plan (the “Finisar Incentive Plan”). Each Assumed Finisar RSU is subject to substantially the same terms and conditions as applied to the Assumed Finisar RSU immediately prior to the Effective Time, except that the number of shares of II-VI Common Stock subject to each Assumed Finisar RSU has been adjusted in accordance with the terms of the Merger Agreement. Accordingly, an aggregate of 4,023,481 shares of the Company’s common stock, no par value (“Company Common Stock”), is issuable in connection with the Assumed Finisar RSUs. Other than the Assumed Finisar RSUs, the Company did not assume any other awards outstanding under the Finisar Incentive Plan at the Effective Time. In addition, as of the Effective Time, the Company assumed (i) the Finisar Corporation 401(k) Profit Sharing Plan (the “Finisar 401(k) Plan”) and (ii) the unused capacity under the Finisar Incentive Plan. Accordingly, the Registration Statement also relates to 1,000,000 shares of Company Common Stock issuable pursuant to the Finisar 401(k) Plan and 930,563 shares of Company Common Stock issuable pursuant to the Finisar Incentive Plan.

This opinion letter is being delivered in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act.

You have requested our opinions as to the matters set forth below in connection with the Registration Statement. For purposes of rendering those opinions, we have examined copies of the Finisar Incentive Plan, the Finisar 401(k) Plan, the Registration Statement, the Company’s Amended and Restated Articles of Incorporation, the Company’s Amended and Restated By-Laws, the Merger Agreement, and the corporate actions of the Company with respect to the Finisar Incentive Plan and the Finisar 401(k) Plan, the Registration Statement and the Shares, and we have made such other investigation as we have deemed appropriate. We also have examined and relied upon certificates of public officials and, in rendering our opinion, we have made the assumptions that are customary in opinion letters of this kind. We have not verified any of those assumptions.

Based upon and subject to the foregoing and the additional qualifications and other matters set forth below, we are of the opinion that the Shares have been duly and validly authorized and that the Shares, when issued in accordance with the terms of the Finisar Incentive Plan or the Finisar 401(k) Plan, as applicable, will be validly issued, fully paid and nonassessable.

The opinions expressed in this opinion letter are limited to the Business Corporation Law of the Commonwealth of Pennsylvania. The foregoing opinions are rendered as of the date of this letter. We assume no obligation to update or supplement any of such opinions in order to reflect any changes of law or fact that may occur.

We are furnishing this opinion letter to you solely in connection with the Registration Statement. You may not rely on this opinion letter in any other connection, and it may not be furnished to or relied upon by any other person for any purpose, without our specific prior written consent. We hereby consent to the filing of this opinion as Exhibit 5.1 to the Registration Statement and to the use of our name wherever appearing in the Registration Statement. In giving our consent, we do not thereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations thereunder.

Very truly yours,
