Explanatory Note

This Amendment No. 1 to the Current Report on Form 8-K amends Item 8.01 of the Current Report on Form 8-K filed by Coherent, Inc., a Delaware corporation (“Coherent”), on June 15, 2021 (the “Original Form 8-K”), solely to correct certain scrivener's errors with respect to certain information previously disclosed as part of the supplemental disclosures in the Original Form 8-K. No other changes have been made to the Original Form 8-K.

Item 8.01 Other Events

As previously disclosed, on March 25, 2021, Coherent, II-VI Incorporated (“II-VI”), a Pennsylvania corporation, and Watson Merger Sub Inc., a Delaware corporation and a wholly owned subsidiary of II-VI (“Merger Sub”), entered into an Agreement and Plan of Merger (the “Merger Agreement”). Pursuant to the terms of the Merger Agreement, the acquisition of Coherent will be accomplished through a merger of Merger Sub with and into Coherent (the “Merger”), with Coherent surviving the Merger. A definitive joint proxy statement/prospectus was filed with the U.S. Securities and Exchange Commission (the “SEC”) by II-VI on May 6, 2021 (the “joint proxy statement/prospectus”), in connection with, among other things, the Merger Agreement.

Certain Litigation

As previously disclosed in the joint proxy statement/prospectus, between April 28, 2021 and May 4, 2021, three lawsuits were filed by purported stockholders of Coherent in connection with the transactions contemplated by the Merger Agreement, under the captions Stein v. Coherent, Inc., et al., Civil Action No. 1:21-cv-3775 (S.D.N.Y.), Shirey v. Coherent, Inc., et al., Case 2:21-cv-10698-JMV-AME (N.J.), and Diaz v. Coherent, Inc., et al., Case 1:21-cv-03990 (S.D.N.Y.). Six additional lawsuits were filed between May 7, 2021 and June 10, 2021 by purported stockholders of Coherent in connection with the transactions contemplated by the Merger Agreement under the captions Acosta v. Coherent, Inc., et al., Case No. 1:21-cv-04108 (S.D.N.Y.), Wolf v. Coherent, Inc., et. al., Case No. 1:21-cv-04848 (S.D.N.Y.), Lawrence v. Coherent, Inc., et. al., Case No. 1:21-cv-00808-UNA (Del.), Finger v. Coherent, Inc., et. al., Case No. 5:21-cv-04217 (N.D. Cal.), Waterman v. Coherent, Inc., et. al., Case No. 1:21-cv-02623 (E.D. Pa.), and Anderson v. Coherent, Inc., et. al., Case No. 5:21-cv-04505 (N.D. Cal.). The complaints name as defendants Coherent and members of the Coherent board of directors. Certain complaints additionally name as defendants II-VI and Merger Sub. The complaints allege, among other things, that the defendants violated Sections 14(a) and 20(a) of the Exchange Act, by filing a materially incomplete and misleading registration statement on Form S-4 in connection with the Merger.

While Coherent believes that the disclosures set forth in the joint proxy statement/prospectus comply fully with all applicable law and denies the allegations in the pending actions described above, in order to moot plaintiffs’ disclosure claims, avoid nuisance and possible expense and business delays, and provide additional information to its stockholders, Coherent has determined voluntarily to supplement certain disclosures in the joint proxy statement/prospectus related to plaintiffs’ claims with the supplemental disclosures set forth below (the “Supplemental Disclosures”). Nothing in the Supplemental Disclosures shall be deemed an admission of the legal merit, necessity or materiality under applicable laws of any of the disclosures set forth herein. To the contrary, Coherent specifically denies all allegations in the various litigation matters that any additional disclosure was or is required or material.

SUPPLEMENTAL DISCLOSURES

This supplemental information should be read in conjunction with the joint proxy statement/prospectus, which should be read in its entirety, including the cautionary notes regarding the risks and limitations associated with relying on prospective financial information. The inclusion in this supplement to the joint proxy statement/prospectus of certain summary unaudited prospective financial information should not be regarded as an indication that any of Coherent, II-VI or their respective affiliates, officers, directors or other representatives, or any other recipient of this information, considered, or now considers, it to be material or to be reliably predictive of actual future results, and the unaudited prospective financial information should not be relied upon as such. To the extent defined terms are used but not defined herein, they have the meanings set forth in the joint proxy statement/prospectus.

The disclosure under the heading “Certain Unaudited Prospective Financial Information” beginning on page 133 of the joint proxy statement/prospectus is hereby amended by including the following at the end of the eighth paragraph under that heading (such paragraph being the first full paragraph on page 135):

Financial measures included in forecasts provided to a financial advisor for use in connection with a business combination transaction are excluded from the definition of non-GAAP financial measures and therefore, are not subject to SEC rules regarding disclosures of non-GAAP financial measures, which would otherwise require a reconciliation of a non-GAAP financial measure to a GAAP financial measure. Accordingly, we have not provided a reconciliation of the financial measures included in the company projections which have been provided to BofA Securities and Credit Suisse for purposes of preparing their financial analyses and opinions.

The disclosure under the heading “II-VI Adjusted Prospective Financial Information” on page 138 of the joint proxy statement/prospectus is hereby amended by including the following at the end of the first paragraph under that heading:

The disclosure under the heading “Summary of Material Coherent Financial Analyses” beginning on page 107 of the joint proxy statement/prospectus is hereby amended and supplemented by replacing the tenth and eleventh paragraphs under that heading (such paragraphs beginning on page 109 and continuing on to page 110) in their entirety with the following:

Discounted Cash Flow Analysis. BofA Securities performed a discounted cash flow analysis of Coherent to calculate the estimated present value of the standalone unlevered, after-tax free cash flows that Coherent was forecasted to generate during Coherent’s second, third and fourth quarters of fiscal year 2021 and fiscal years 2022 through 2026 based on the Coherent forecasts. BofA Securities calculated terminal values for Coherent by applying to Coherent’s estimated standalone unlevered, after-tax free cash flow of $271 million for the terminal year a range of perpetuity growth rates of 3.0% to 4.0%, which perpetuity growth rates were selected based on BofA Securities’ professional judgment and experience. The cash flows and terminal values were then discounted to present value, assuming a mid-year convention, as of December 31, 2020 using discount rates ranging from 8.5% to 11.5%, which were based on an estimate of Coherent’s weighted average cost of capital, derived using the capital asset pricing model, which took into account, among other things, risk free rate, unlevered beta, and historical equity risk premium and BofA Securities’ professional judgment and experience. From the resulting enterprise values, BofA Securities added net cash of $85 million to derive equity values.

This analysis indicated the following approximate implied per share equity value reference ranges for Coherent (rounded to the nearest $0.25) as compared to the per share price of Coherent common stock implied by the merger consideration:

Implied Per Share Equity Value Reference Range for Coherent		Per Share Price Implied by Merger Consideration
$104.75 - $196.25		$281.21

The disclosure under the heading “Opinions of Coherent’s Financial Advisors – Opinion of BofA Securities” beginning on page 103 is hereby amended and supplemented by replacing the second, third, fourth and fifth bullet points of the fourth paragraph under that heading (such paragraph beginning on page 104) in their entirety with the following:

• reviewed certain internal financial and operating information with respect to the business, operations and prospects of Coherent furnished to or discussed with BofA Securities by the management of Coherent, including certain financial forecasts relating to Coherent prepared by or at the direction of and approved by the management of Coherent (such forecasts we refer to as “Coherent forecasts” and are set forth in the section titled “The Merger—Certain Unaudited Prospective Financial Information—Coherent Prospective Financial Information—C. Coherent management case prospective financial information” beginning on page 136 of this joint proxy statement/prospectus);

• reviewed certain internal financial and operating information with respect to the business, operations and prospects of II-VI furnished to or discussed with BofA Securities by the management of II-VI, including certain financial forecasts relating to II-VI prepared by the management of II-VI (such forecasts we refer to as “II-VI forecasts” and are set forth in the section titled “The Merger—Certain Unaudited Prospective Financial Information—II-VI Prospective Financial Information” beginning on page 137 of this joint proxy statement/prospectus);

• reviewed an alternative version of the II-VI forecasts incorporating certain adjustments thereto made by the management of Coherent and certain extrapolations thereto prepared by or at the direction of and approved by the management of Coherent (such forecasts we refer to as “adjusted II-VI forecasts” and are set forth in the section titled “The Merger—Certain Unaudited Prospective Financial Information—Coherent-Adjusted II-VI Prospective Financial Information” beginning on page 137 of this joint proxy statement/prospectus) and discussed with the management of Coherent its assessments as to the relative likelihood of achieving the future financial results reflected in the II-VI forecasts and the adjusted II-VI forecasts;

• reviewed certain estimates furnished to BofA Securities by the management of Coherent as to the amount and timing of cost savings and the costs of achieving such results (which we refer to as the “cost savings” and are set forth in the section titled “The Merger—Certain Unaudited Prospective Financial Information—Certain Potential Combined Company Cost Savings and Revenue Synergies” beginning on page 139 of this joint proxy statement/prospectus) anticipated by the managements of Coherent and II-VI to result from the merger;

The disclosure under the heading “Summary of Material Coherent Financial Analyses” beginning on page 107 of the joint proxy statement/prospectus is hereby amended and supplemented by replacing the twelfth paragraph under that heading (such paragraph beginning on page 110) in its entirety with the following:

Other Factors. BofA Securities also noted certain additional factors that were not considered part of BofA Securities’ material financial analyses with respect to its opinion but were referenced for informational purposes, including, among other things, the following:

Discounted Cash Flow Analysis. BofA Securities performed a discounted cash flow analysis of II-VI to calculate the estimated present value of the standalone unlevered, after-tax free cash flows that II-VI was forecasted to generate during II-VI’s third and fourth quarters of fiscal year 2021 and fiscal years 2022 through 2026 based on the adjusted II-VI forecasts. BofA Securities calculated terminal values for II-VI by applying to II-VI’s estimated standalone unlevered, after-tax free cash flow of $968 million for the terminal year a range of perpetuity growth rates of 2.5% to 3.5%, which perpetuity growth rates were selected based on BofA Securities’ professional judgment and experience. The cash flows and terminal values were then discounted to present value, assuming mid-year convention, as of December 31, 2020 using discount rates ranging from 7.0% to 9.0%, which were based on an estimate of II-VI’s weighted average cost of capital, derived using the capital asset pricing model, which took into account, among other things, risk free rate, unlevered beta, and historical equity risk premium and BofA Securities’ professional judgment and experience. From the resulting enterprise values, BofA Securities subtracted net debt of $689 million to derive equity values.

This analysis indicated the following approximate implied per share equity value reference ranges for II-VI (rounded to the nearest $0.25), as compared to the closing price of II-VI common stock on March 23, 2021:

Implied Per Share Equity Value Reference Range for II-VI		Closing Trading Price of II-VI on March 23, 2021

The disclosure under the heading “Summary of Material Relative Financial Analyses” beginning on page 112 of the joint proxy statement/prospectus is hereby amended and supplemented by replacing the first and second paragraphs under that heading in their entirety with the following:

Pro Forma Analysis. BofA Securities performed a pro forma analysis to calculate the theoretical change in value for Coherent stockholders resulting from the merger based on a comparison of (i) the pro forma ownership by Coherent stockholders of the combined company following the merger and (ii) the 100% ownership by Coherent stockholders of the Coherent common stock on a standalone basis. For Coherent on a standalone basis, BofA Securities used the reference range obtained in its discounted cash flow analysis described above under “—Summary of Material Coherent Financial Analyses—Discounted Cash Flow Analysis.” BofA Securities then calculated the implied pro forma equity value per share of Coherent common stock resulting from the merger as follows:

(a)

the implied equity value of Coherent on a standalone basis plus the implied equity value of II-VI on a standalone basis (each as calculated using the discounted cash flow analysis described above);

(b)

plus the implied equity value of net estimated cost savings to the combined company applying a perpetuity growth rate of 3.0% to 4.0% and a discount rate range of 8.5% to 11.5% (based on the perpetuity growth rates and discount rates used in the discounted cash flow analysis with respect to Coherent as described above);

(c)

less the decrease in cash from the merger to the combined company; and

(d)

plus $220.00 cash per share included in the merger consideration.

This analysis yielded the following implied per share equity value reference ranges for Coherent common stock on a standalone basis and, assuming pro forma ownership by Coherent stockholders set forth in the table below, for the combined company, excluding payment in kind interest payable on the II-VI Series B convertible preferred stock (rounded to the nearest $0.25):

		Per Share Equity Value Reference Ranges for Coherent Common Stock
		Low			Midpoint			High
Standalone	$	104.75		$	136.50		$	196.25
Pro Forma⁽¹⁾	$	286.75		$	315.75		$	367.75
Coherent Stockholders Ownership⁽¹⁾		15.8	%		13.9	%		13.8	%

(1)

Treats shares of II-VI Series B convertible preferred stock as debt in the event that such preferred stock is out of the money.

The disclosure under the heading “Financial Analyses Regarding Coherent” beginning on page 118 of the joint proxy statement/prospectus is hereby amended and supplemented by replacing the ninth paragraph under that heading (such paragraph beginning on page 120) in its entirety with the following:

Discounted Cash Flow Analysis Regarding Coherent. Credit Suisse also performed a discounted cash flow analysis with respect to Coherent by calculating the estimated net present value of the projected after-tax, unlevered free cash flows of Coherent, treating stock-based compensation as a cash expense, based on the Coherent management case prospective financial information. Credit Suisse applied, based on its experience and professional judgment, a range of terminal value multiples of 10.0x to 12.0x to the Coherent Adjusted EBITDA estimate for the fiscal year ending September 2026 and discount rates ranging from 8.5% to 10.5% derived from a weighted average cost of capital calculation, by application of the capital asset pricing model. The discounted cash flow analysis indicated the following approximate implied equity value per share reference range for Coherent common stock, as compared to the implied value of the merger consideration:

Implied Per Share Equity Value Reference Range		Per Share Price Implied by Merger Consideration
$163.89 - $209.68		$281.21

The disclosure under the heading “Other Matters” beginning on page 122 of the joint proxy statement/prospectus is hereby amended and supplemented by replacing the second paragraph under that heading (such paragraph beginning on page 123) in their entirety with the following:

The disclosure under the heading “Opinions of BofA Securities” on page 20 of the joint proxy statement/prospectus is hereby amended and supplemented by replacing the last sentence of the first paragraph under that heading with the following:

The disclosure under the heading "Miscellaneous" on page 113 of the joint proxy statement/prospectus is hereby amended and supplemented by replacing the fourth paragraph, under that heading in its entirety with the following:

Coherent also has agreed to reimburse BofA Securities for its reasonable expenses incurred in connection with BofA Securities’ engagement and to indemnify BofA Securities, its affiliates, and each of their respective directors, officers, employees and agents and each other controlling person of BofA Securities or any of its affiliates against specified liabilities, including liabilities under the federal securities laws.
