Item 1.01. Entry into a Material Definitive Agreement.

On December 10, 2021, II-VI Incorporated (the “Company”) issued $990 million aggregate principal amount of its 5.000% senior notes due 2029 (the “Notes”) pursuant to an Indenture, dated as of December 10, 2021 (the “Indenture”), among the Company, the guarantors party thereto and U.S. Bank National Association, as trustee (the “Trustee”). The Notes are guaranteed by each of the Company’s domestic subsidiaries that guarantee its existing credit agreement. The Notes were offered and sold either to persons reasonably believed to be “qualified institutional buyers” pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”) or to persons outside the United States under Regulation S of the Securities Act. Interest on the Notes will be payable on December 15 and June 15 of each year, commencing on June 15, 2022, at a rate of 5.000% per annum. The Notes will mature on December 15, 2029.

The Company intends to use the proceeds from the Offering, together with other financing sources (including the Term Facilities (as defined below)) and cash on hand, to fund the cash consideration, the repayment of certain indebtedness and certain fees and expenses in connection with the Company’s previously announced pending business combination with Coherent, Inc. (“Coherent”), pursuant to an Agreement and Plan of Merger, dated March 25, 2021 (the “Agreement and Plan of Merger”), by and among the Company, Coherent and Watson Merger Sub Inc., a wholly owned subsidiary of the Company (the “Coherent Acquisition”).

On or after December 15, 2024, the Company may redeem the Notes, in whole at any time or in part from time to time, at the redemption prices set forth in the Indenture, plus accrued and unpaid interest, if any, to, but excluding, the applicable redemption date. In addition, at any time prior to December 15, 2024, the Company may redeem the Notes, at its option, in whole at any time or in part from time to time, at a redemption price equal to 100% of the principal amount of the Notes redeemed, plus a “make-whole” premium set forth in the Indenture, plus accrued and unpaid interest, if any, to, but excluding, the applicable redemption date. Notwithstanding the foregoing, at any time and from time to time prior to December 15, 2024, the Company may redeem up to 40% of the aggregate principal amount of the Notes using the proceeds of certain equity offerings as set forth in the Indenture, at a redemption price equal to 105.000% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but excluding, the applicable redemption date. In addition, if (i) the consummation of the Coherent Acquisition has not been consummated on or prior to 11:59 p.m., Eastern Time, on December 15, 2022 or (ii) the Company informs the Trustee in writing or otherwise announces in writing that the Coherent Acquisition is no longer being pursued and/or the Agreement and Plan of Merger has been terminated without consummation of the Coherent Acquisition, then the Company will be required to redeem all of the outstanding notes at a redemption price equal to 100% of the principal amount of the notes, plus accrued and unpaid interest, if any, to, but excluding, the applicable redemption date.

The Indenture contains customary covenants and events of default, including, default relating to among other things, payment default, failure to comply with covenants or agreements contained in the Indenture or the Notes and certain provisions related to bankruptcy events.

The foregoing description of the Indenture is only a summary and does not purport to be complete and is qualified in its entirety by reference to the full text of the Indenture, a copy of which is filed as Exhibit 4.1 to this Current Report on Form 8-K and is incorporated herein by reference.

Item 2.03. Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

The information provided in Item 1.01 of this Current Report on Form 8-K is incorporated by reference herein.

Item 8.01. Other Events.

On December 10, 2021, the Company issued a press release announcing the closing of the Offering and the allocation and pricing of a new term loan A credit facility (the “Term Loan A Facility”) in an aggregate principal amount of $850 million, a new term loan B credit facility (the “Term Loan B Facility” and, together with the Term Loan A Facility, the “Term Facilities”) in an aggregate principal amount of $2,800 million, and a new revolving credit facility (the “Revolving Credit Facility”) in an aggregate principal amount of $350 million, which Term Facilities are expected to be borrowed in connection with the closing of the Coherent Acquisition. The Revolving Credit Facility is expected to be available concurrently with the closing of the Coherent Acquisition. The Term A Facility and Revolving Credit Facility borrowings in U.S. dollars will each bear interest at LIBOR (subject to a 0.00% floor) plus a range of 1.75% to 2.50%, depending on the Company’s total net leverage ratio. The Term A Facility and the Revolving Credit Facility Borrowings are initially expected to bear interest at LIBOR plus 2.00%. The Term Loan B Facility will bear interest at LIBOR (subject to a 0.50% floor) plus 2.75%. A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated by reference herein.

The information contained in this report, including the exhibits hereto, shall not constitute an offer to sell, or a solicitation of an offer to purchase, any Notes in any jurisdiction in which such an offer, solicitation or sale would be unlawful.
