Exhibit 99.1

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

Introduction

On March 25, 2021, II-VI Incorporated (which we refer to as “II-VI”), Coherent, Inc. (which we refer to as “Coherent”) and Watson Merger Sub Inc., a newly formed wholly owned subsidiary of II-VI (which we refer to as “Merger Sub”), entered into an Agreement and Plan of Merger (which we refer to as 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 (which we refer to as the “merger”), with Coherent surviving the merger.

Previously on June 30, 2020, II-VI announced its intention to offer, in concurrent underwritten public offerings, newly issued shares of II-VI common stock and newly issued shares of II-VI Series A mandatory convertible preferred stock. On July 7, 2020, the public offerings were consummated, and II-VI used the proceeds from the public offerings to pay off the remaining balance of $715 million on its senior secured term B loan facility with Bank of America, N.A (referred to herein as “Bank of America”). We refer to the transactions described in this paragraph as the “public offerings”.

Previously on September 24, 2019, II-VI completed its acquisition of Finisar Corporation (which we refer to as “Finisar”), a global technology leader for subsystems and components for fiber optic communications (which we refer to as the “Finisar acquisition”).

The following unaudited pro forma condensed combined financial information has been prepared in accordance with Article 11 of Regulation S-X as amended by the final rule, Release No. 33-10786 “Amendments to Financial Disclosures about Acquired and Disposed Businesses”.

The unaudited pro forma condensed combined balance sheet as of March 31, 2021 gives effect to the merger, the equity financing (as defined herein), and the debt financing (as defined herein), as if those transactions had been completed on March 31, 2021 and combines the unaudited consolidated balance sheet of II-VI as of March 31, 2021 with Coherent’s unaudited consolidated balance sheet as of April 3, 2021.

The unaudited pro forma condensed combined statements of earnings (loss) for the year ended June 30, 2020 and the nine months ended March 31, 2021 give effect to the merger, the equity financing, the debt financing, the public offerings and the Finisar acquisition as if they had occurred on July 1, 2019, the first day of II-VI’s fiscal year 2020, and combines the historical results of II-VI, Coherent and Finisar (see “Description of the Financing” for explanation of the equity financing and debt financing). The unaudited pro forma condensed combined statement of earnings (loss) for the fiscal year ended June 30, 2020 combines the audited consolidated statement of earnings (loss) of II-VI for the fiscal year ended June 30, 2020, Coherent’s unaudited consolidated statement of operations for the twelve months ended July 4, 2020 and Finisar’s unaudited consolidated statement of operations for the three month period ended July 28, 2019. The unaudited pro forma condensed combined statement of earnings (loss) for the nine months ended March 31, 2021 combines the unaudited consolidated statement of earnings of II-VI for the nine months ended March 31, 2021 with Coherent’s unaudited consolidated statement of operations for the nine months ended April 3, 2021.

The historical financial statements of II-VI, Coherent and Finisar have been adjusted in the accompanying unaudited pro forma condensed combined financial information to give effect to pro forma events that are transaction accounting adjustments which are necessary to account for the merger, the equity financing, the debt financing, the public offerings and the Finisar acquisition, in accordance with U.S. GAAP. The unaudited pro forma adjustments are based upon available information and certain assumptions that our management believe are reasonable.

The unaudited pro forma condensed combined financial information should be read in conjunction with:

• The accompanying notes to the unaudited pro forma condensed combined financial information;

• The separate audited consolidated financial statements of II-VI as of and for the fiscal year ended June 30, 2020 and the related notes, included in II-VI’s Annual Report on Form 10-K for the fiscal year ended June 30, 2020;

• The separate audited consolidated financial statements of Coherent as of and for the fiscal year ended October 3, 2020 and the related notes, included in Coherent’s Annual Report on Form 10-K, as amended, for the fiscal year ended October 3, 2020;

• The separate unaudited condensed consolidated financial statements of Finisar as of and for the three months ended July 28, 2019 and the related notes, included in Finisar’s Quarterly Report on Form 10-Q for the period ended July 28, 2019, incorporated by reference into II-VI’s Current Report on Form 8-K/A filed December 9, 2019.

Description of the Merger

On March 25, 2021, II-VI, Merger Sub and Coherent entered into the merger agreement, pursuant to which II-VI agreed to acquire Coherent. Upon completion of the merger, each share of Coherent common stock issued and outstanding immediately prior to the effective time will be converted into the right to receive (A) $220.00 in cash, without interest (which we refer to as the “cash consideration”), plus (B) 0.91 of a validly issued, fully paid and nonassessable share of II-VI common stock (together with the cash consideration, the “merger consideration”). Further, under the terms of the merger agreement:

• Each time- or performance-based Coherent RSU (other than any Coherent director RSU) that is outstanding immediately prior to the effective time will be converted into an award (which we refer to as a “converted RSU”) covering that number of shares of II-VI common stock, rounded down to the nearest whole share, equal to the product of (x) the number of shares of Coherent common stock subject to such award of Coherent RSUs (and, with respect to any Coherent PSUs, the number of shares of Coherent common stock will be determined based on the greater of the target or actual level of achievement of such goals or metrics immediately prior to the effective time, as determined by the Coherent board or a committee thereof) and (y) the sum of (A) 0.91 and (B) the quotient obtained by dividing (i) the $220.00 cash consideration by (ii) the volume weighted average price of a share of II-VI common stock for a ten trading day period, starting with the opening of trading on the 11th trading day prior to the closing date to the closing of trading on the second to last trading day prior to the closing date, as reported by Bloomberg.

• Each Coherent director RSU that is outstanding immediately prior to the effective time will, automatically and without any required action on the part of the holder thereof, vest (if unvested) and be cancelled and converted into the right to receive the merger consideration as if such Coherent director RSU had been settled in shares of Coherent common stock immediately prior to the effective time.

• A holder’s Coherent RSUs will immediately vest in certain circumstances involving a termination of employment in connection with a change in control. At this time, II-VI has not made any decisions with respect to labor matters of the combined company. Accordingly, no adjustments have been made to the unaudited pro forma condensed combined financial statements to reflect any such accelerated vesting.

Description of the Financing

In connection with entering into the merger agreement, II-VI entered into the debt commitment letter. Subject to the terms of the debt commitment letter, the commitment parties have committed to provide a senior secured term loan “A” facility in an aggregate principal amount of $850 million, a senior secured term loan “B” facility in an aggregate principal amount of $2,800 million, a senior secured revolving credit facility in an aggregate principal amount of $350 million and a senior unsecured bridge loan facility in an aggregate principal amount of $1,125 million (which we refer to as the “bridge loan facility” and collectively with the other foregoing facilities, the “facilities”). The bridge loan facility will only be drawn to the extent II-VI is unable to issue senior unsecured notes or other debt securities at or prior to the closing of the merger in an amount sufficient to

2

close the transaction. The funding of the facilities provided for in the debt commitment letter is contingent on the satisfaction of customary conditions, including the execution and delivery of definitive documentation with respect to the facilities in accordance with the terms sets forth in the debt commitment letter and the consummation of the merger in accordance with the merger agreement. For the purposes of this unaudited pro forma condensed combined financial information, II-VI intends to draw $100 million on the senior secured revolving credit facility and $1,000 million on the bridge loan facility. The debt financing contemplated under the debt commitment letter is referred to herein as the “debt financing”.

In connection with entering into the merger agreement, on March 30, 2021, II-VI entered into the investment agreement. On March 31, 2021, pursuant to the investment agreement, II-VI and BCPE consummated the initial investment of $750 million through the issuance and sale of the shares of II-VI Series B-1 convertible preferred stock. Pursuant to the investment agreement and subject to the terms and conditions set forth therein, II-VI and the investors expect to consummate the subsequent investment of $1.4 billion, immediately prior to the closing of the merger. The issuance and sale of the shares of II-VI Series B-2 convertible preferred stock in the subsequent investment is contingent upon the consummation of the merger in accordance with the merger agreement and is subject to certain other closing conditions customary for transactions of this type. The equity financing contemplated under the investment agreement is referred to herein as the “equity financing”. The equity financing and debt financing are collectively referred to as the “financing”.

Accounting for the Merger

The merger is being accounted for as a business combination using the acquisition method with II-VI as the accounting acquirer in accordance with Accounting Standards Codification (“ASC”) Topic 805, Business Combinations. Under this method of accounting, the aggregate merger consideration will be allocated to Coherent’s assets acquired and liabilities assumed based upon their estimated fair values at the date of completion of the merger. The process of valuing the net assets of Coherent immediately prior to the merger, as well as evaluating accounting policies for conformity, is preliminary. Any differences between the estimated fair value of the consideration transferred and the estimated fair value of the assets acquired and liabilities assumed will be recorded as goodwill. Accordingly, the aggregate merger consideration allocation and related adjustments reflected in this unaudited pro forma condensed combined financial information are preliminary and subject to revision based on a final determination of fair value. Refer to Note 1—Basis of Presentation for more information.

II-VI plans to finance the merger with cash from the combined company balance sheets, proceeds from the issuance of new II-VI Series B convertible preferred stock in the equity financing, and new debt incurred in the debt financing, as well as the issuance of II-VI Common Stock as merger consideration. In addition, II-VI expects to use proceeds from the debt and equity financing to pay off the remaining balance on the II-VI senior secured first-lien term A loan facility with Bank of America.

The unaudited pro forma condensed combined financial information presented is for informational purposes only and is not necessarily indicative of the financial position or results of operations that would have been realized if the merger, the equity financing, the debt financing, the public offerings and the Finisar acquisition had been completed on the dates set forth above, nor is it indicative of the future results or financial position of the combined company.

NOTES TO THE UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

Note 1 - Basis of Presentation

The unaudited pro forma condensed combined financial information and related notes are prepared in accordance with Article 11 of Regulation S-X as amended by the final rule, Release No. 33-10786 “Amendments to Financial Disclosures about Acquired and Disposed Businesses”.

II-VI, Coherent and Finisar’s historical financial statements were prepared in accordance with U.S. GAAP and presented in U.S. dollars. As discussed in Note 2, certain reclassifications were made to align II-VI, Coherent and Finisar’s financial statement presentation. II-VI is currently in the process of evaluating Coherent’s accounting policies, which will be finalized upon completion of the merger, or as more information becomes available. As a result of that review, additional differences could be identified between the accounting policies of the two companies. With the information currently available, II-VI has determined that no significant adjustments are necessary to conform Coherent’s financial statements to the accounting policies used by II-VI.

The unaudited pro forma condensed combined financial information was prepared using the acquisition method of accounting in accordance with ASC 805, with II-VI as the accounting acquirer, using the fair value concepts defined in ASC Topic 820, Fair Value Measurement, and based on the historical consolidated financial statements of II-VI, Coherent and Finisar. Under ASC 805, all assets acquired and liabilities assumed in a business combination are recognized and measured at their assumed acquisition date fair value, while transaction costs associated with the business combination are expensed as incurred. The excess of merger consideration over the estimated fair value of assets acquired and liabilities assumed, if any, is allocated to goodwill.

The allocation of the aggregate merger consideration depends upon certain estimates and assumptions, all of which are preliminary. The allocation of the aggregate merger consideration has been made for the purpose of developing the unaudited pro forma condensed combined financial information. The final determination of fair values of assets acquired and liabilities assumed relating to the merger could differ materially from the preliminary allocation of aggregate merger consideration. The final valuation will be based on the actual net tangible and intangible assets of Coherent existing at the acquisition date.

The unaudited pro forma condensed combined balance sheet, as of March 31, 2021, the unaudited pro forma condensed combined statement of earnings (loss) for the year ended June 30, 2020 and the unaudited pro forma condensed combined statement of earnings (loss) for the nine months ended March 31, 2021 presented herein, are based on the historical financial statements of II-VI, Coherent and Finisar. Because of different fiscal period ends, and pursuant to Rule 11- 02(c)(3) of Regulation S-X requiring fiscal period-ends to be within one quarter between the acquirer and acquiree, the following was applied:

• The unaudited pro forma condensed combined balance sheet as of March 31, 2021 is presented as if II-VI’s acquisition of Coherent had occurred on March 31, 2021 and combines the historical balance sheet of II-VI as of March 31, 2021 with the historical balance sheet of Coherent as of April 3, 2021.

• The unaudited pro forma condensed combined statement of earnings (loss) for the year ended June 30, 2020 has been prepared as if the merger, the public offerings and the Finisar acquisition had occurred on July 1, 2019 and combines II-VI’s historical statement of earnings (loss) for the fiscal year ended June 30, 2020 with Coherent’s historical statement of operations for the twelve month period ended July 4, 2020, along with Finisar’s historical statement of operations for the three month period ended July 28, 2019.

• Coherent’s historical statement of operations for the twelve month period ended July 4, 2020 was prepared by taking the unaudited consolidated statement of operations for the nine months ended July 4, 2020, adding the audited consolidated statement of operations for the fiscal year ended September 28, 2019, and subtracting the unaudited consolidated statement of operations for the nine months ended June 29, 2019.

7

• Since the Finisar acquisition closed on September 24, 2019, Finisar’s results of operations are presented in the II-VI results for the period of September 24, 2019 to June 30, 2020. The results of Finisar for the three month period ended July 28, 2019 is included to derive a twelve month unaudited pro forma condensed combined statement of operations ended June 30, 2020. In addition, the period between September 24, 2019 and September 30, 2019 has been removed for purposes of the unaudited condensed combined pro forma statement of earnings (loss) for the year ended June 30, 2020.

• The unaudited pro forma condensed combined statement of earnings (loss) for the nine months ended March 31, 2021 has been prepared as if the merger had occurred on July 1, 2019 and combines II-VI’s historical statement of earnings (loss) for the nine months ended March 31, 2021 with Coherent’s historical statement of operations for the nine months ended April 3, 2021.

• Coherent’s historical statement of operations for the nine months ended April 3, 2021 was prepared by taking the unaudited consolidated statement of operations for the six months ended April 3, 2021, adding the audited consolidated statement of operations for the fiscal year ended October 3, 2020 and subtracting the unaudited consolidated statement of operations for the nine months ended July 4, 2020.

The unaudited pro forma condensed combined financial information does not reflect any anticipated synergies or dissynergies, operating efficiencies or cost savings that may result from the merger or any acquisition and integration costs that may be incurred. The pro forma adjustments represent II-VI management’s best estimates and are based upon currently available information and certain assumptions that II-VI believes are reasonable under the circumstances. II-VI is not aware of any material transactions between II-VI and Coherent during the periods presented. Accordingly, adjustments to eliminate transactions between II-VI and Coherent have not been reflected in the unaudited pro forma condensed combined financial information.

Note 2 - II-VI, Coherent, and Finisar reclassification adjustments

During the preparation of this unaudited pro forma condensed combined financial information, management performed a preliminary analysis of Coherent’s financial information to identify differences in accounting policies as compared to those of II-VI and differences in financial statement presentation as compared to the presentation of II-VI. With the information currently available, II-VI has determined that no significant adjustments are necessary to conform Coherent’s financial statements to the accounting policies used by II-VI. However, certain reclassification adjustments have been made to conform Coherent’s historical financial statement presentation to II-VI’s financial statement presentation. Following the merger, the combined company will finalize the review of accounting policies and reclassifications, which could be materially different from the amounts set forth in the unaudited pro forma condensed combined financial information presented herein. This section also includes reclassification adjustments related to the historical Finisar information included for the unaudited pro forma condensed combined statement of earnings (loss) for the fiscal year ended June 30, 2020.

Note 3 – Preliminary purchase price allocation

Estimated Aggregate Merger Consideration

The following table summarizes the estimated aggregate merger consideration for Coherent with reference to II-VI’s share price of $63.57 on May 17, 2021:

(000’s)	Amount
Estimated cash paid for outstanding Coherent common stock (i)	$	5,397,117
Estimated shares of II-VI common stock issued to Coherent stockholders (ii)		1,419,165
Estimated converted Coherent RSUs attributable to pre-combination service (iii)		65,000
Estimated payment of Coherent debt (iv)		427,908
Estimated consideration for Coherent director RSUs (v)		1,600
Preliminary estimated aggregate merger consideration	$	7,310,790

(i) The cash component of the estimated aggregate merger consideration is based on 24,532,350 shares of outstanding Coherent common stock being exchanged and the $220 per share cash portion of the merger consideration.

(ii) Value of estimated shares of II-VI common stock issued is based on 24,532,350 shares of outstanding Coherent common stock being exchanged and 0.91 of a share of II-VI common stock at a closing share price of $63.57 on May 17, 2021.

(iii) As discussed in “Description of the Merger’’, certain equity awards of Coherent will be replaced by II-VI’s equity awards with similar terms. The portion of the estimated fair value of II-VI’s equity awards attributable to the pre-combination service period represents aggregate merger consideration. The remainder of the fair value will be recognized as compensation expense subsequent to the merger.

(iv) The estimated cash paid by II-VI to settle Coherent’s Euro Term Loan and outstanding line of credit borrowings of $417.9 million and $10.0 million, respectively.

(v) Estimated consideration for Coherent director RSUs represents the settlement of Coherent RSUs granted to members of the Coherent board. The estimated consideration consists of $1.3 million in cash consideration and $0.3 million in consideration in shares of II-VI common stock.

The preliminary estimated aggregate merger consideration could significantly differ from the amounts presented due to movements in the II-VI share price up to the closing date. A sensitivity analysis related to the fluctuation in the II-VI share price was performed to assess the impact a hypothetical change of 10% on the closing price of II-VI common stock on May 17, 2021 would have on the estimated aggregate merger consideration as of the closing date:

	Stock Price		Total Estimated Consideration
10% increase	$	69.93	$	7,452,706
10% decrease	$	57.21	$	7,168,873

Preliminary Aggregate Merger Consideration Allocation

The assumed accounting for the merger, including the aggregate merger consideration, is based on provisional amounts, and the associated purchase accounting is not final. The preliminary allocation of the purchase price to the acquired assets and assumed liabilities was based upon the preliminary estimate of fair values. For the preliminary estimate of fair values of assets acquired and liabilities assumed of Coherent, II-VI used publicly available benchmarking information as well as a variety of other assumptions, including market participant assumptions. II-VI is expected to use widely accepted income-based, market-based, and cost-based valuation approaches upon finalization of purchase accounting for the merger. Actual results may differ materially from the assumptions within the accompanying unaudited pro forma condensed combined financial information. The unaudited pro forma adjustments are based upon available information and certain assumptions that II-VI believes are reasonable under the circumstances. The purchase price adjustments relating to the Coherent and II-VI combined financial information are preliminary and subject to change, as additional information becomes available and as additional analyses are performed.

The following table summarizes the preliminary aggregate merger consideration allocation, as if the merger had been completed on March 31, 2021:

(000’s)	Amount
Assets:
Cash and cash equivalents	$	353,049
Restricted cash		1,534
Accounts receivable		248,856
Inventories (i)		491,835
Prepaid and other current assets		98,343
Other intangible assets, net (ii)		2,445,459
Property, plant & equipment, net (iii)		294,873
Non-current restricted cash		4,508
Deferred income taxes		161,113
Other assets		126,813
Goodwill		4,186,696
Liabilities:
Current portion of long-term debt		1,856
Accounts payable		93,028
Accrued compensation and benefits		78,656
Operating lease current liabilities		15,900
Accrued income taxes payable		9,614
Other accrued liabilities		128,919
Long-term debt		4,133
Deferred income taxes		578,728
Operating lease liabilities		68,301
Other liabilities		123,154
Estimated aggregate merger consideration	$	7,310,790

14

(i) The unaudited pro forma condensed combined balance sheet has been adjusted to record Coherent’s inventories at a preliminary fair value of approximately $491.8 million, an increase of $98.2 million from the carrying value. The unaudited pro forma condensed combined statement of earnings (loss) for the year ended June 30, 2020 has been adjusted to recognize additional cost of goods sold related to the increased basis. The additional costs are not anticipated to affect the condensed combined statements of earnings (loss) beyond twelve months after the acquisition date.

(ii) Preliminary identifiable intangible assets in the unaudited pro forma condensed combined financial information consists of the following:

(000’s)	Preliminary Fair Value		Estimated Useful Life
Preliminary fair value of intangible assets acquired
Trade names and trademarks	$	102,351		5.8 years
Customer relationships		771,288		10.5 years
Developed technology		1,571,820		8.5 years
Intangible assets acquired	$	2,445,459

A 10% change in the valuation of intangible assets would cause a corresponding increase or decrease in the amortization expense of approximately $20.7 million for the nine months ended March 31, 2021 and $27.6 million for the year ended June 30, 2020. Pro forma amortization is preliminary and based on the use of straight-line amortization. The amount of amortization following the merger may differ significantly between periods based upon the final value assigned and amortization methodology used for each identifiable intangible asset.

(iii) The unaudited pro forma condensed combined balance sheet has been adjusted to record Coherent’s property, plant and equipment (consisting of land, buildings and improvements, equipment, furniture and fixtures, and leasehold improvements) at a preliminary fair value of approximately $294.9 million, an increase of $30.1 million from the carrying value. The unaudited pro forma condensed combined statements of earnings (loss) have been adjusted to recognize additional depreciation expense related to the increased basis under cost of goods sold. The additional depreciation expense is computed with the assumption that the various categories of assets will be depreciated over a useful life of 10-15 years on a straight-line basis.

Cash from issuance of II-VI Series B convertible preferred stock, net of equity issuance costs		1,358,000
Payment of II-VI debt (iv)		(1,072,969	)
Net pro forma transaction accounting adjustment - financing to cash and cash equivalents	$	4,919,218

(i) These costs consist of legal advisory, financial advisory, accounting and consulting costs.

(ii) One-time payment to settle equity awards for directors, as described in Note 3 above.

(iii) The estimated cash paid by II-VI to settle Coherent’s Euro Term Loan and outstanding line of credit borrowings of $417.9 million and $10.0 million, respectively.

(iv) The estimated cash paid to settle II-VI’s senior secured first-lien term A loan facility with Bank of America including accrued interest.

(b) Reflects the preliminary purchase accounting adjustment for inventories based on the acquisition method of accounting.

(000’s)	Amount
Pro forma transaction accounting adjustments:
Elimination of Coherent’s inventories - carrying value	$	(393,672	)
Preliminary fair value of acquired inventories		491,835
Net pro forma transaction accounting adjustment to inventories	$	98,163

Represents the adjustment of acquired inventories to its preliminary estimated fair value.

(ii) The extinguishment of II-VI’s unamortized debt issuance costs will not affect the condensed combined statements of earnings (loss) beyond twelve months after the acquisition date.

(iii) The new interest expense on transaction financing adjustments included in the unaudited pro forma condensed combined statements of earnings (loss) reflect the interest expense and amortization of debt issuance costs associated with new debt from the commitment parties. Interest was recognized for Term Loan A, Term Loan B, and the Senior Bridge Facility using the effective interest method with the rate equal to the Adjusted LIBO Rate plus 2.25% per annum for Term Loan A, Adjusted LIBO Rate plus 2.875% per annum for Term Loan B, and Adjusted LIBO Rate plus 5% for the Senior Bridge Facility (with the spread increasing by 0.50% for each period of three months). The Revolving Facility assumes an interest rate equal to that of Term Loan A. The Senior Bridge Facility is assumed to be short-term borrowing and is a backstop in the event that II-VI cannot secure new financing with the commitment parties. Per the terms of the commitment letter, the senior bridge loan is automatically converted to a senior extended term loan with a maturity of seven years after the conversion date if after one year II-VI has failed to raise permanent financing. For the purposes of the unaudited pro forma condensed combined financial information, the conversion and extension of the term loan is assumed, along with the applicable interest rate, which is a maximum of 7.25% per the terms of the commitment letter.

A sensitivity analysis on interest expense for the year ended June 30, 2020 and the nine months ended March 31, 2021 has been performed to assess the effect of a 12.5 basis point change of the hypothetical interest on the debt financing. The following table shows the change in the interest expense for the debt financing transaction described above:

(000’s)	For the Nine Months Ended March 31, 2021			For the Year Ended June 30, 2020
Interest expense assuming:
Increase of 0.125%	$	3,505		$	4,789
Decrease of 0.125%	$	(3,505	)	$	(4,789	)

(e) To record the income tax impact of the pro forma adjustments utilizing a statutory income tax rate in effect of 22% for the year ended June 30, 2020 and for the nine months ended March 31, 2021. The effective tax rate of the combined company could be significantly different (either higher or lower) depending on post-merger activities, including cash needs, the geographical mix of income and changes in tax law. Because the tax rates used for the pro forma financial information are estimated, the blended rate will likely vary from the actual effective rate in periods subsequent to completion of the merger. This determination is preliminary and subject to change based upon the final determination of the fair value of the acquired assets and assumed liabilities.

(f) Reflects the adjustment to record the dividends to holders of shares of II-VI Series B convertible preferred stock, which accrue dividends at a 5% annual rate, compounding on a quarterly basis regardless of whether or not there are earnings or profits and accretion related to the equity issuance costs of the shares of II-VI Series B convertible preferred stock in the equity financing.
