II-VI Incorporated and Subsidiaries

Notes to Condensed Consolidated Financial Statements (Unaudited)

Note 1.    Basis of Presentation

The condensed consolidated financial statements of II-VI Incorporated (“II-VI”, the “Company”, “we”, “us” or “our”) for the three months ended September 30, 2020 and 2019 are unaudited. In the opinion of management, all adjustments considered necessary for a fair presentation for the periods presented have been included. All adjustments are of a normal recurring nature unless disclosed otherwise. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K dated August 26, 2020. The condensed consolidated results of operations for the three months ended September 30, 2020 are not necessarily indicative of the results to be expected for the full fiscal year. The Condensed Consolidated Balance Sheet information as of June 30, 2020 was derived from the Company’s audited consolidated financial statements.

On September 24, 2019, the Company completed its acquisition of Finisar Corporation (“Finisar”). The Company’s condensed consolidated financial statements include the operating results of Finisar from the date of acquisition. Refer to Note 3 for further discussion of the acquisition.

In March 2020, the World Health Organization declared the outbreak of COVID-19 as a pandemic, which continues to spread throughout the United States and world. We are closely monitoring the impact of the COVID-19 pandemic on all aspects of our business including the impact to our suppliers and customers as well as the impact to the countries and markets in which we operate. At the onset of the COVID-19 outbreak, we began focusing intensely on mitigating the adverse impacts of COVID-19 on our foreign and domestic operations starting by protecting our employees, suppliers and customers.

Note 2.    Recently Issued Financial Accounting Standards

Financial Instruments - Credit Losses

In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-13, Financial Instruments - Credit Losses (Topic 326), which modifies the measurement of expected credit losses on certain types of financial instruments, including trade receivables. The Company adopted this standard on July 1, 2020. The adoption did not have a material impact on the Company's condensed consolidated financial statements.

Note 3.    Finisar Acquisition

On September 24, 2019 (the “Closing Date”), the Company completed its acquisition of Finisar, a global technology leader for subsystems and components for fiber optic communications.

The purchase price allocation set forth herein is final. The Company utilized widely accepted income-based, market-based, and cost-based valuation approaches to perform the purchase price allocation. Income-based valuation approaches included the use of the discounted cash flow and relief-from-royalty methods for certain acquired intangible assets.

Our final allocation of the purchase price of Finisar, based on the estimated fair value of the assets acquired and liabilities assumed as of the Closing Date, is as follows (in $000):

	Final Purchase Price Allocation
	Previously				Measurement
	Reported		Reclassification		Period
	September 30, 2019		Adjustments		Adjustments (a)		As Adjusted
Cash and cash equivalents	$	842,764	$	(287)	$	—	$	842,477
Accounts receivable	260,864		—		(1,523)		259,341

Deferred tax assets	—		—		16,267		16,267
Accounts payable	(123,707)		—		—		(123,707)
Other accrued liabilities (a)	(148,425)		(43,964)		(3,199)		(195,588)
Deferred tax liabilities (a)	(197,809)		43,964		85,179		(68,666)
Debt	(575,000)		—		—		(575,000)
Goodwill (a)	759,239		—		155,051		914,290
Total Purchase Price	$	2,914,964	$	—	$	(6,461)	$	2,908,503

(a) During the quarter ended September 30, 2020, the Company finalized its warranty reserve liabilities resulting in a reduction of other accrued liabilities by approximately $6.5 million, with a corresponding decrease to goodwill and deferred tax liabilities.

Note 4.    Other Acquisitions and Investments

Acquisition of Ascatron AB

On August 20, 2020, the Company acquired all of the outstanding shares of Ascatron AB, located in Sweden. The acquisition will add essential elements to the Company's vertically integrated silicon carbide technology platform. Purchase price consideration totaled $36.7 million.

Due to the timing of the acquisition, the Company is in the process of measuring the fair value of assets acquired and liabilities assumed, including tangible and intangible assets and related deferred income taxes. The following table presents a

preliminary allocation of the purchase price of the assets acquired and liabilities assumed at the date of acquisition ($000):

Assets
Developed technology	$	20,000
Goodwill	18,922
Other assets	2,511
Total assets acquired	$	41,433
Liabilities
Non-interest bearing liabilities	$	(203)
Deferred tax liability	(4,526)
Total liabilities assumed	(4,729)
Net assets acquired	$	36,704

9

The goodwill is recorded in the Compound Semiconductor segment and is attributed to the workforce acquired as part of the transaction. The goodwill is non-deductible for income tax purposes. Transaction expenses related to the acquisition totaled $1.9 million for three months ended September 30, 2020 and is included in Selling, General and Administrative expenses in the Condensed Consolidated Statement of Earnings.

The amount of revenues and net earnings from the acquisition included in the Company’s Condensed Consolidated Statement of Earnings for the three months ended September 30, 2020 were insignificant.

Purchase of Equity Investment in INNOViON Corporation

As of September 30, 2020, the Company holds a 93.8% equity investment in INNOViON Corporation ("Innovion"), a leader in ion implantation technology for silicon and compound semiconductor devices, which was acquired in November 2017 for $51.5 million. The Company’s pro-rata share of earnings from this investment for the three months ended September 30, 2020 and 2019 was insignificant.

This investment is accounted for under the equity method of accounting. The following table summarizes the Company's equity in this nonconsolidated investment:

Location	Interest Type	Ownership % as of September 30, 2020	Equity as of September 30, 2020 ($000)
USA	Equity Investment	93.8%	$	59,539

Innovion was determined to be a variable interest entity because the Company had an overall 93.8% economic position in Innovion, comprising a significant portion of its capitalization, but had only a 25% voting interest. The Company’s right to receive rewards and obligation to absorb expected losses was disproportionate to its voting interest. The Company was not the primary beneficiary because it did not have the power to direct the activities of the equity investment that most significantly impacts its economic performance. Certain business decisions, including decisions with respect to operating budgets, material capital expenditures, indebtedness, significant acquisitions or dispositions, and strategic decisions, require the approval of owners holding a majority percentage in Innovion.  The Company previously accounted for its interest as an equity method investment as the Company had the ability to exercise significant influence over operating and financial policies of Innovion.

As of September 30, 2020 and June 30, 2020, the Company’s maximum financial statement exposure related to Innovion was approximately $59.5 million and $58.8 million, respectively, which is included in Investments on the Condensed Consolidated Balance Sheets.

On August 10, 2020, the Company entered into an agreement to acquire all the outstanding interests of Innovion. The Company acquired the remaining outstanding interests of Innovion on October 1, 2020.

Senior Credit Facilities

The Company currently has Senior Credit Facilities with Bank of America, N.A., as Administrative Agent, Swing Line Lender and an L/C Issuer, and the other lenders party thereto.

The Credit Agreement provides for senior secured financing of $2.425 billion in the aggregate, consisting of

12

(i)Aggregate principal amount of $1,255 million for a five-year senior secured first-lien term A loan facility (the “Term A Facility”),

(ii)Aggregate principal amount of $720 million for a seven-year senior secured term B loan facility (the “Term B Facility” and together with the Term A Facility, the “Term Loan Facilities”), which was repaid in full during the quarter ended September 30, 2020, and

(iii)Aggregate principal amount of $450 million for a five-year senior secured first-lien revolving credit facility (the “Revolving Credit Facility” and together with the Term Loan Facilities, the “Senior Credit Facilities”).

The Credit Agreement also provides for a letter of credit sub-facility not to exceed $25.0 million and a swing loan sub-facility initially not to exceed $20.0 million.

The Term B Facility was repaid in full by the Company subsequent to the public offerings that closed on July 7, 2020. In conjunction with the repayment, the Company paid $0.6 million in associated interest and expensed $24.7 million of debt issuance costs related to the Term B Facility.

The Company is obligated to repay the outstanding principal amount of the Term A Facility in quarterly installments equal to 1.25% of the initial aggregate principal amount of the Term A Facility, with the remaining outstanding balance due and payable on the fifth anniversary of the Closing Date.

The Company’s obligations under the Senior Credit Facilities are guaranteed by each of the Company’s existing or future direct and indirect domestic subsidiaries, including Finisar and its domestic subsidiaries (collectively, the “Guarantors”). Borrowings under the Senior Credit Facilities are collateralized by a first priority lien in substantially all of the assets of the Company and the Guarantors, except that no real property is collateral under the Senior Credit Facilities.

All amounts outstanding under the Senior Credit Facilities will become due and payable 120 days prior to the maturity of the Company’s currently outstanding 0.25% Convertible Senior Notes due 2022 (the “II-VI Notes”) if (i) the II-VI Notes remain outstanding, and (ii) the Company has insufficient cash and borrowing availability to repay the principal amount of the II-VI Notes.

Amounts outstanding under the Senior Credit Facilities will bear interest at a rate per annum equal to an applicable margin over a eurocurrency rate or an applicable margin over a base rate determined by reference to the highest of (a) the federal funds rate plus 0.50%, (b) Bank of America, N.A.’s prime rate and (c) a eurocurrency rate plus 1.00%, in each case as calculated in accordance with the terms of the Credit Agreement. The applicable interest rate would increase under certain circumstances relating to events of default.  The Company has entered into an interest rate swap contract to hedge its exposure to interest rate risk on its variable rate borrowings under the Senior Credit Facilities.  Refer to Note 16 for further information regarding this interest rate swap.

The Credit Agreement contains customary affirmative and negative covenants with respect to the Senior Credit Facilities, including limitations with respect to liens, investments, indebtedness, dividends, mergers and acquisitions, dispositions of assets and transactions with affiliates. The Company will be obligated to maintain a consolidated interest coverage ratio (as calculated in accordance with the terms of the Credit Agreement) as of the end of each fiscal quarter of not less than 3.00:1.00. The Company will be obligated to maintain a consolidated total net leverage ratio (as calculated in accordance with the terms of the Credit Agreement) of not greater than (i) 5.00 to 1.00 for the first four fiscal quarters after the Closing Date, commencing with the first full fiscal quarter after the Closing Date, (ii) 4.50 to 1.00 for the fifth fiscal quarter through and including the eighth fiscal quarter after the Closing Date, and (iii) 4.00 to 1.00 for each subsequent fiscal quarter. As of September 30, 2020, the Company was in compliance with all financial covenants under the Credit Agreement.

0.50% Finisar Convertible Notes

Finisar’s outstanding 0.50% Convertible Senior Notes due 2036 (the “Finisar Notes”) may be redeemed at any time on or after December 22, 2021 in whole or in part at the option of the Company at a redemption price equal to one hundred percent (100)% of the principal amount of such Finisar Notes plus accrued and unpaid interest. Each holder of Finisar Notes also may require Finisar to repurchase all or any portion of such holder’s outstanding Finisar Notes for cash on December 15, 2021, December 15, 2026 and December 15, 2031 at a repurchase price equal to one hundred percent (100%) of the principal amount of such Finisar Notes plus accrued and unpaid interest. The Finisar Notes will mature on December 15, 2036. Interest on the Finisar Notes accrues at 0.50% per annum, paid semi-annually, in arrears, on June 15 and December 15 of each year.

13

In connection with the acquisition of Finisar, the Company, Finisar and the trustee entered into a First Supplemental Indenture, dated as of September 24, 2019 (the “First Supplemental Indenture”). The First Supplemental Indenture supplements the base indenture (as supplemented, the “Finisar Indenture”), which governs the Finisar Notes. Pursuant to the terms of the First Supplemental Indenture, the Company has fully and unconditionally guaranteed, on a senior unsecured basis, the due and punctual payment and performance of all obligations of Finisar to the holders of the Finisar Notes. The First Supplemental Indenture also provides that the right of holders of Finisar Notes to convert Finisar Notes into cash and/or shares of Finisar’s common stock, is changed to a right to convert Finisar Notes into cash and/or shares of the Company’s common stock, subject to the terms of the Finisar Indenture.

Under the terms of the Finisar Indenture, the consummation and effectiveness of the Merger on the Closing Date constituted a Fundamental Change (as defined in the Finisar Indenture) and a Make-Whole Fundamental Change (as defined in the Finisar Indenture). Accordingly, in accordance with the terms of the Finisar Indenture, each holder of Finisar Notes had the right to (i) convert its Finisar Notes into cash and/or shares of Company Common Stock, at Finisar’s option, or (ii) require that Finisar repurchase such holder’s Finisar Notes for an amount in cash equal to one hundred percent (100)% of the principal amount of such Finisar Notes plus accrued and unpaid interest.

Holders of approximately $560.1 million in aggregate principal amount of Finisar Notes exercised the repurchase right. The Company repurchased those Finisar Notes on October 23, 2019 for an aggregate consideration of approximately $561.1 million in cash, including accrued interest. No holders of Finisar Notes exercised the related conversion right. The Company borrowed $561.0 million under a delayed draw on its Term Loan A to fund the payment to the holders of Finisar Notes that exercised the repurchase right. As of September 30, 2020, approximately $14.9 million in aggregate principal amount of Finisar Notes remain outstanding.

0.25% Convertible Senior Notes

In August 2017, the Company issued and sold $345 million aggregate principal amount of the II-VI Notes in a private placement to qualified institutional buyers within the meaning of Rule 144A under the Securities Act of 1933, as amended.

As a result of our cash conversion option, the Company separately accounted for the value of the embedded conversion option as a debt discount. The value of the embedded conversion option was determined based on the estimated fair value of the debt without the conversion feature, which was determined using an expected present value technique (income approach) to estimate the fair value of similar nonconvertible debt; the debt discount is being amortized as additional non-cash interest expense over the term of the II-VI Notes using the effective interest method.

The equity component is not remeasured as long as it continues to meet the conditions for equity classification. The initial conversion rate is 21.25 shares of common stock per $1,000 principal amount of II-VI Notes, which is equivalent to an initial conversion price of $47.06 per share of common stock. Throughout the term of the II-VI Notes, the conversion rate may be adjusted upon the occurrence of certain events. The if-converted value of the II-VI Notes amounted to $297.4 million as of September 30, 2020 and $346.2 million as of June 30, 2020 (based on the Company’s closing stock price on the last trading day of the fiscal periods then ended). As of September 30, 2020, the II-VI Notes are not yet convertible based upon the II-VI Notes’ conversion features.  Holders of the II-VI Notes will not receive any cash payment representing accrued and unpaid interest upon conversion of a II-VI Note. Accrued but unpaid interest will be deemed to be paid in full upon conversion rather than cancelled, extinguished or forfeited.

The following tables set forth total interest expense recognized related to the II-VI Notes for the three months ended September 30, 2020 and September 30, 2019 ($000):

	Three Months Ended September 30, 2020		Three Months Ended September 30, 2019
0.25% contractual coupon	$	220	$	220
Amortization of debt discount and debt issuance costs including initial purchaser discount	3,407		3,255
Interest expense	$	3,627	$	3,475

The effective interest rate on the liability component for both periods presented was 4.5%. The unamortized discount amounted to $23.8 million as of September 30, 2020 and is being amortized over three years.

14

Aggregate Availability

The Company had aggregate availability of $399.6 million under its line of credit as of September 30, 2020.

Weighted Average Interest Rate

The weighted average interest rate of total borrowings was 1.8% and 1.9% for the three months ended September 30, 2020 and 2019, respectively.

Note 10.    Income Taxes

The Company’s year-to-date effective income tax rate at September 30, 2020 was 22.3% compared to a benefit of 14.8% for the same period in 2019. The variations between the Company’s effective tax rate and the U.S. statutory rate of 21% were primarily due to the impact of the U.S. enacted tax legislation partially offset by research and development incentives in certain jurisdictions and foreign tax credits. 

U.S. GAAP prescribes the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements which includes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. As of September 30, 2020 and June 30, 2020, the Company’s gross unrecognized income tax benefit, excluding interest and penalties, was $40.5 million and $42.8 million, respectively. The Company has classified $7.4 million of uncertain tax positions as current income tax liabilities and the remaining uncertain tax positions of $33.1 million as noncurrent income tax liabilities, as the amounts are not expected to be paid within one year. If recognized, $37.7 million of the gross unrecognized tax benefits at September 30, 2020 would impact the effective tax rate. The Company recognizes interest and penalties related to uncertain tax positions in the income tax provision in the Condensed Consolidated Statements of Earnings (Loss). The amount of accrued interest and penalties included in the gross unrecognized income tax benefit was $3.6 million and $3.8 million at September 30, 2020 and June 30, 2020, respectively. Fiscal years 2017 to 2021 remain open to examination by the U.S. Internal Revenue Service, fiscal years 2015 to 2021 remain open to examination by certain state jurisdictions, and fiscal years 2009 to 2019 remain open to examination by certain foreign taxing jurisdictions.  The Company is currently under examination for certain subsidiary companies in the Philippines for the year 2017; Germany for the years 2012 through 2015; Australia for the years 2011 through 2014; and India for the year 2016. The Company believes its income tax reserves for these tax matters are adequate.

Note 11.    Leases

On July 1, 2019, the Company adopted Topic 842, Leases, using the modified retrospective transition approach. We determine if an arrangement is a lease at inception and classify it as either finance or operating. The Company's portfolio of leases contains certain real estate, equipment and vehicle leases.

The Company’s lease liabilities are recognized based on the present value of the remaining fixed lease payments, over the lease term, using a discount rate of similarly secured borrowings available to the Company. For the purpose of lease liability measurement, we consider only payments that are fixed and determinable at the time of commencement. Any variable payments that depend on an index or rate are expensed as incurred. We account for non-lease components, such as common area maintenance, as a component of the lease, and include it in the initial measurement of our lease assets and corresponding liabilities. The Company’s lease terms and conditions may include options to extend or terminate. An option is recognized when it is reasonably certain that we will exercise that option.

The Company’s lease assets also include any lease payments made and exclude any lease incentives received prior to commencement. Our lease assets are tested for impairment in the same manner as long-lived assets used in operations.

The following table presents lease costs, which include short-term leases, lease term, and discount rates ($000):

Note 12.    Equity

Mandatory Convertible Preferred Stock

On July 2, 2020, II-VI announced the pricing of an underwritten public offering of 2,000,000 shares of 6.00% Series A Mandatory Convertible Preferred, no par value per share (“Mandatory Convertible Preferred Stock”), resulting in gross proceeds to II-VI from the offering of $400 million, before deducting the underwriting discounts and commissions and offering expenses payable by the Company (the "Preferred Stock Offering"). In addition, the underwriters had a 30-day option to purchase up to an additional 300,000 shares of Series A Mandatory Convertible Preferred Stock at the applicable public offering price, less underwriting discounts and commissions and solely to cover over-allotments with respect to the preferred stock offering. On July 2, 2020, the underwriters exercised the option in full, raising an additional approximately $60 million in gross proceeds. On July 7, 2020, the Company closed the Preferred Stock Offering, including the issuance and sale of 2.3 million shares of Mandatory Convertible Preferred Stock.

Upon conversion on the mandatory conversion date, as determined in accordance with the terms of the Mandatory Convertible Preferred Stock, each outstanding share of the Mandatory Convertible Preferred Stock, unless previously converted, will automatically convert into a number of shares of the Company's common stock equal to not more than 4.6512 shares of common stock and not less than 3.8760 shares of common stock (the “Minimum Conversion Rate”), depending on the applicable market value of the common stock, determined in accordance with the terms of the Mandatory Convertible Preferred Stock and subject to certain anti-dilution adjustments.

Other than in the event of one of certain fundamental changes, a holder of Mandatory Convertible Preferred Stock may, at any time prior to July 1, 2023, elect to convert such holder’s shares of Mandatory Convertible Preferred Stock, in whole or in part (but in no event less than one share of Mandatory Convertible Preferred Stock), at the Minimum Conversion Rate per share of Mandatory Convertible Preferred Stock, subject to certain anti-dilution adjustments.

If one of certain fundamental changes occurs on or prior to July 1, 2023, holders of the Mandatory Convertible Preferred Stock will have the right to convert their shares of Mandatory Convertible Preferred Stock, in whole or in part (but in no event less than one share of the Mandatory Convertible Preferred Stock), into shares of the Company's common stock at the conversion rate determined in accordance with the terms of the Mandatory Convertible Preferred Stock during the period beginning on, and including, the effective date of such change and ending on, and including, the date that is 20 calendar days after the effective date of such fundamental change (or, if later, the fundamental date that is 20 calendar days after holders receive notice of such fundamental change, but in no event later than July 1, 2023). Holders who convert their shares of the Mandatory Convertible Preferred Stock during that period will also receive a dividend make-whole amount and, to the extent there is any, the accumulated dividend amount, in each case as calculated in accordance with the terms of the Mandatory Convertible Preferred Stock.

The Company recognized $6.4 million of accrued preferred stock dividends, which were presented as other accrued liabilities on our Condensed Consolidated Balance Sheet as of September 30, 2020.

	Three Months Ended September 30, 2020
Dividends per share	$	2.80
Series A Mandatory Convertible Preferred Stock dividends ($000)	$	6,440

Common Stock Offering

On July 2, 2020, II-VI announced the pricing of an underwritten public offering of 9,302,235 shares of its common stock at a public offering price of $43.00 per share, resulting in gross proceeds to II-VI from the offering of approximately $400 million, before deducting the underwriting discounts and commissions and offering expenses payable by II-VI (the “Common Stock Offering”). In addition, the underwriters had a 30-day option to purchase up to an additional 1,395,335 shares of its common stock at the applicable public offering price, less underwriting discounts and commissions. On July 2, 2020, the underwriters exercised the option in full, raising an additional approximately $60 million in gross proceeds. On July 7, 2020, the Company closed the Common Stock Offering, including the issuance and sale of approximately 10.7 million shares of Common Stock.

Note 13.    Earnings Per Share

Basic earnings (loss) per common share is computed by dividing net earnings (loss) available to common shareholders by the weighted-average number of shares of common stock outstanding during the period.

17

Diluted earnings (loss) per common share is computed by dividing the diluted earnings (loss) available to common shareholders by the weighted-average number of shares of common stock and potentially dilutive shares of common stock outstanding during the period. The dilutive effect of equity awards is calculated based on the average stock price for each fiscal period, using the treasury stock method. Diluted shares outstanding include the dilutive effect of the potential shares of the Company's common stock issuable from stock options, performance and restricted shares.

Potentially dilutive shares whose effect would have been antidilutive are excluded from the computation of diluted earnings (loss) per common share. For the three months ended September 30, 2020, diluted earnings (loss) per share excluded the potentially dilutive effect of the potential shares of the Company's common stock issuable upon conversion of outstanding convertible debt as well as the potentially dilutive effect of the Mandatory Convertible Preferred Stock (under the If-Converted method), as their effects were anti-dilutive.

The following is a reconciliation of the numerators and denominators of the basic and diluted earnings (loss) per share computations for the periods presented ($000):

	Three Months Ended September 30,

Note 14.    Segment Reporting

The Company reports its business segments using the “management approach” model for segment reporting. This means that the Company determines its reportable business segments based on the way the chief operating decision maker organizes business segments within the Company for making operating decisions and assessing financial performance.

The Company reports its financial results in the following two segments: (i) Compound Semiconductors, and (ii) Photonic Solutions, and the Company’s chief operating decision maker receives and reviews financial information based on these segments.  The Company evaluates business segment performance based upon segment operating income, which is defined as earnings before income taxes, interest and other income or expense. The segments are managed separately due to the market, production requirements and facilities unique to each segment.

Ascatron is presented within the Compound Semiconductors segment since the date of acquisition.

The accounting policies are consistent across each segment. To the extent possible, the Company’s corporate expenses and assets are allocated to the segments. Unallocated and Other includes eliminating inter-segment sales and transfers, the results of Finisar since the acquisition date through September 30, 2019, and transaction costs related to the Finisar transaction.

The following tables summarize selected financial information of the Company’s operations by segment ($000):

Note 15.    Share-Based Compensation

The Company’s Board of Directors adopted the II-VI Incorporated 2018 Omnibus Incentive Plan (the “Plan”), which was approved by the Company’s shareholders. The Plan provides for the grant of performance-based cash incentive awards, non-qualified stock options, stock appreciation rights, restricted share awards, restricted share units, deferred share awards, performance share awards and performance share units to employees, officers and directors of the Company. The maximum number of shares of the Company’s Common Stock authorized for issuance under the Plan is limited to 3,550,000 shares of Common Stock, not including any remaining shares forfeited under the predecessor plans that may be rolled into the Plan. The Company records share-based compensation expense for these awards in accordance with U.S. GAAP, which requires the

19

recognition of grant-date fair value of share-based compensation in net earnings (loss) and over the requisite service period of the individual grantees, which generally equals the vesting period. The Company accounts for cash-based stock appreciation rights, cash-based restricted share unit awards and cash-based performance share unit awards as liability awards, in accordance with applicable accounting standards.  

Upon consummation of the acquisition of Finisar, the Company assumed approximately 6.6 million restricted stock units previously granted by Finisar under the Amended and Restated Finisar Corporation 2005 Stock Incentive Plan (each an “Assumed RSU”), and the Company also assumed the unused capacity under the Finisar 2005 Plan.

Share-based compensation expense for the periods indicated was as follows ($000):

	Three Months Ended
September 30,	2020		2019
Stock options and cash-based stock appreciation rights	$	1,920	$	1,670
Restricted share awards and cash-based restricted share unit awards	10,110		12,731
Performance share awards and cash-based performance share unit awards	3,472		1,759
	$	15,502	$	16,160

Note 16.    Fair Value of Financial Instruments

The FASB defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous markets for the asset and liability in an orderly transaction between market participants at the measurement date. The Company estimates fair value of its financial instruments utilizing an established three-level hierarchy in accordance with U.S. GAAP. The hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date as follows:

•Level 1 –Valuation is based upon unadjusted quoted prices for identical assets or liabilities in active markets.

•Level 2 –Valuation is based upon quoted prices for similar assets and liabilities in active markets, or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instruments.

•Level 3 –Valuation is based upon other unobservable inputs that are significant to the fair value measurements.

The classification of fair value measurements within the hierarchy is based upon the lowest level of input that is significant to the measurement.

The Company entered into an interest rate swap with a notional amount of $1,075 million to limit the exposure to its variable interest rate debt by effectively converting it to a fixed interest rate. The Company receives payments based on the one-month LIBOR and makes payments based on a fixed rate of 1.52%. The Company receives payments with a floor of 0.00%. The interest rate swap agreement has an effective date of November 24, 2019, with an expiration date of September 24, 2024. The initial notional amount of the interest rate swap is scheduled to decrease to $825 million in June 2022 and will remain at that amount through the expiration date. The Company designated this instrument as a cash flow hedge and deemed the hedge relationship effective at inception of the contract. The fair value of the interest rate swap of $44.6 million is recognized in the Condensed Consolidated Balance Sheet within other liabilities as of September 30, 2020. Changes in fair value are recorded within accumulated other comprehensive income (loss) on the Condensed Consolidated Balance Sheet and reclassified into the Condensed Consolidated Statement of Earnings (Loss) as interest expense in the period in which the underlying transaction affects earnings.  Cash flows from hedging activities are reported in the Condensed Consolidated Statements of Cash Flows in the same classification as the hedged item, generally as a component of cash flows from operations. The fair value of the interest rate swap is determined using widely accepted valuation techniques and reflects the contractual terms of the interest rate swap including the period to maturity, and while there are no quoted prices in active markets, it uses observable market-based inputs, including interest rate curves. The fair value analysis also considers a credit valuation adjustment to reflect nonperformance risk of both the Company and the single counterparty. The interest rate swap is classified as a Level 2 item within the fair value hierarchy.

The Company estimated the fair value of the II-VI Notes and Finisar Notes based on quoted market prices as of the last trading day prior to September 30, 2020; however, the II-VI Notes and Finisar Notes have only a limited trading volume and as such this fair value estimate is not necessarily the value at which the II-VI Notes and Finisar Notes could be retired or transferred.

20

The Company concluded that this fair value measurement should be categorized within Level 2. The carrying value of the II-VI Notes and Finisar Notes is net of unamortized discount and issuance costs. See Note 9. Debt for details on the Company’s debt facilities.

The fair value and carrying value of the II-VI Notes and Finisar Notes were as follows at September 30, 2020 ($000):

	Fair Value		Carrying Value
II-VI Notes	$	390,619	$	317,719
Finisar Notes	13,734		14,888

The fair values of cash and cash equivalents are considered Level 1 among the fair value hierarchy and approximate fair value because of the short-term maturity of those instruments. The Company’s borrowings including its lease obligations, excluding the 0.25% Convertible Notes and the 0.50% Finisar convertible notes are considered Level 2 among the fair value hierarchy and their principal amounts approximate fair value.

Note 17.    Share Repurchase Programs

In August 2014, the Company’s Board of Directors authorized the Company to purchase up to $50 million of its Common Stock through a share repurchase program (the “Program”) that calls for shares to be purchased in the open market or in private transactions from time to time. The Program has no expiration and may be suspended or discontinued at any time. Shares purchased by the Company are retained as treasury stock and available for general corporate purposes.  The Company did not repurchase share pursuant to this Program during the quarter ended September 30, 2020. Through September 30, 2020, the Company has cumulatively purchased 1,416,587 shares of its Common Stock pursuant to the Program for approximately $22.3 million.

Note 18.    Accumulated Other Comprehensive Income (Loss)

The changes in accumulated other comprehensive income (loss) (“AOCI”) by component, net of tax, for the three months ended September 30, 2020 were as follows ($000):

	Foreign Currency Translation Adjustment		Interest Rate Swap		Defined Benefit Pension Plan		Total Accumulated Other Comprehensive Income (Loss)
AOCI - June 30, 2020	$	(31,596)	$	(44,085)	$	(11,702)	$	(87,383)
Other comprehensive income before reclassifications	35,524		—		—		35,524
Amounts reclassified from AOCI	—		(555)		—		(555)
Net current-period other comprehensive income	35,524		(555)		—		34,969
AOCI - September 30, 2020	$	3,928	$	(44,640)	$	(11,702)	$	(52,414)

Critical Accounting Estimates

The preparation of financial statements and related disclosures are in conformity with accounting principles generally accepted in the United States of America and the Company’s discussion and analysis of its financial condition and results of operations require the Company’s management to make judgments, assumptions and estimates that affect the amounts reported in its condensed consolidated financial statements and accompanying notes. Note 1 of the Notes to Consolidated Financial Statements in the Company’s Annual Report on Form 10-K dated August 26, 2020 describes the significant accounting policies and methods used in the preparation of the Company’s consolidated financial statements.

New Accounting Standards

See Note 2. Recent Accounting Pronouncements to our unaudited condensed consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q for a description of recent accounting pronouncements, including the expected dates of adoption and estimated effects, if any, on our consolidated financial statements.

COVID-19 Update

22

On March 11, 2020, the World Health Organization designated the novel coronavirus known as COVID-19 as a global pandemic. In response to the global spread of COVID-19, governments at various levels have implemented unprecedented response measures. Overall, the COVID-19 pandemic has significantly curtailed global economic activity and caused significant volatility and disruption in global financial markets. Certain of the measures taken in response to the COVID-19 pandemic have adversely affected, and could in the future materially adversely impact, our business, results of operations, financial condition and stock price.

In particular, the COVID-19 pandemic is having a significant impact on global markets due to resulting supply chain and production disruptions, workforce and travel restrictions, quarantines and shelter-in-place orders, reduced spending and other similar measures implemented by many companies and other factors. Following the initial outbreak of COVID-19, we experienced temporary disruptions to our operations in China. While these operations have returned to active service, approximately 45% of our global facilities are subject to a government order, including approximately 10% that are currently closed, most of which are administrative facilities where employees are working remotely. Certain of our customers and suppliers currently are impacted by similar operational restrictions.

Our focus has been on the protection of the health and safety of our employees and business partners. In our facilities, we have deployed new safety measures, including guidance to employees on matters such as effective hygiene and disinfection, social distancing, limited and remote access working where feasible and use of protective equipment. We also are prioritizing efforts to understand and support the changing business needs of our customers and suppliers in light of restrictions that are applicable to them.

At this time, we believe that our existing balances of cash and cash equivalents, along with our existing committed borrowing availability and other short-term liquidity arrangements, will be sufficient to satisfy our working capital needs, make necessary capital asset purchases and debt repayments and meet other liquidity requirements associated with our existing operations. Likewise, our current estimates indicate that we will remain in compliance with financial covenants applicable under our debt arrangements.

The full extent of the impact of the COVID-19 pandemic and the related responses on our operational and financial performance is currently uncertain and will depend on many factors outside our control, including, without limitation, the duration and severity of the pandemic, the imposition of protective public safety measures, and the impact of the pandemic on the global economy as a whole and, in particular, demand for our products. Due to these uncertainties, we cannot reasonably estimate the related impact on us at this time.

For additional information regarding the risks that we face as a result of the COVID-19 pandemic, please see Item 1A, Risk Factors, in the Annual Report on Form 10-K for the year ended June 30, 2020. Further, to the extent the COVID-19 pandemic adversely affects our business and financial results, it also may have the effect of heightening many of the other risks described in the risk factors included in the Annual Report on Form 10-K for the year ended June 30, 2020 and in our subsequent filings with the Securities and Exchange Commission.

Results of Operations ($ in millions, except per share data)

The following tables set forth select items from our Condensed Consolidated Statements of Earnings (Loss) for the three months ended September 30, 2020 and 2019:

Consolidated

Revenues. Revenues for the three months ended September 30, 2020 increased 114% to $728.1 million, compared to $340.4 million for the same period last fiscal year. The addition of Finisar operations contributed $337.6 million revenues during the three months ended September 30, 2020.  In addition to revenue contributed by Finisar, the Company realized increased revenues within its ROADM and 3D Sensing product lines, driven by data center and 5G optical network expansions, and prior year qualifications of additional VCSEL array manufacturing lines for facial biometrics in smartphones.

Gross margin. Gross margin for the three months ended September 30, 2020 was $286.6 million, or 39.4% of total revenues, compared to $123.1 million, or 36.2% of total revenues, for the same period last fiscal year. The increase in the gross margin of 320 basis points for the current quarter compared to the same period last year was driven by the addition of higher margin transceiver products following the Finisar acquisition, as well as favorable product mix within the Photonic Solutions Segment.

Internal research and development. Internal research and development (“IR&D”) expenses for the three months ended September 30, 2020 were $78.2 million, or 10.7% of revenues, compared to $36.1 million, or 10.6% of revenues, for the same period last fiscal year. The increase in IR&D expenses during the three-month period compared to the same period last fiscal year was primarily due to the addition of $37.0 million of Finisar IR&D expense. The Company has maintained its strong internal investments in new products and technologies focused on 3D sensing, 5G, the Cloud, electric vehicles and other emerging markets.

Selling, general and administrative. Selling, general and administrative (“SG&A”) expenses for the three months ended September 30, 2020 were $107.2 million, or 14.7% of revenues, compared to $105.5 million, or 31.0% of revenues, for the same period last fiscal year. The decrease in SG&A as a percentage of revenue for the three-month period compared to the same period last fiscal year was primarily the result of transaction costs incurred in prior year due to the Finisar acquisition.  During the three months ended September 30, 2020, the Company incurred $2.1 million of transaction related expenses, compared to $49.0 million of transaction related expenses incurred in the three months ended September 30, 2019.

Interest and other, net. Interest and other, net for the three months ended September 30, 2020 was expense of $41.6 million, compared to expense of $12.0 million for the same period last fiscal year.  Included in interest and other, net were interest expense on borrowings, equity earnings and losses from its unconsolidated investments, foreign currency gains and losses, expense of debt issuance costs, and interest income on excess cash balances. Interest and other, net includes expense of $24.7 million of debt issuance costs recognized in conjunction with the repayment of the Company's Term B Facility, compared to $4 million of expense recognized in the three months ended September 30, 2019.  Interest expense increased $10.2 million for the current three-month period due to the higher levels of outstanding debt incurred in conjunction with the acquisition of Finisar. In addition, there were foreign currency losses of $4.7 million for the current three-month period due to the volatility in the foreign exchange market, compared to $1.1 million of expense in the three months ended September 30, 2019. Other interest and expense, net was offset by income in equity investments and other insignificant activity.

24

Income taxes. The Company’s year-to-date effective income tax rate at September 30, 2020 was 22.3%, compared to an effective tax rate of 14.8% for the same period last fiscal year. The variations between the Company’s effective tax rate and the U.S. statutory rate of 21% were primarily due to the impact of the U.S. enacted tax legislation, partially offset by research and development incentives in certain jurisdictions and foreign tax credits.

Segment Reporting

Revenues and operating income for the Company’s reportable segments are discussed below. Operating income differs from net earnings (loss) in that operating income excludes certain operational expenses included in other expense (income) – net as reported. Management believes operating income to be a useful measure for investors, as it reflects the results of segment performance over which management has direct control and is used by management in its evaluation of segment performance. See Note 14. Segment Reporting, to our unaudited condensed consolidated financial statements in Part I, Item 1 of this Quarterly Report on Form 10-Q for further information on the Company’s reportable segments and for the reconciliation of the Company’s operating income to net earnings (loss), which is incorporated herein by reference.

Photonic Solutions ($ in millions)

	Three Months Ended September 30,				% Increase
	2020		2019
Revenues	$	497.7	$	141.4	252%
Operating income	$	50.4	$	13.0	287%

Revenues for the three months ended September 30, 2020 for Photonic Solutions increased 252% to $497.7 million, compared to $141.4 million for the same period last fiscal year. The increase in revenues for the three months ended September 30, 2020 compared to the same period last fiscal year was primarily due to the acquisition of Finisar and the strengthening of demand for cloud and 5G optical infrastructure products.

Operating income for the three months ended September 30, 2020 increased 287% to income of $50.4 million, compared to operating income of $13.0 million for the same period last fiscal year.  The increase in operating income during the current three-month period compared to the same period last fiscal year was primarily driven by the incremental margin realized from the increased revenues during the current fiscal quarter, and the realization of synergies and plant efficiency following the Finisar acquisition.

Compound Semiconductors ($ in millions)

	Three Months Ended September 30,				% Increase
	2020		2019
Revenues	$	230.4	$	177.0	30%
Operating income	$	50.7	$	26.5	91%

Revenues for the three months ended September 30, 2020 for Compound Semiconductors increased 30% to $230.4 million, compared to revenues of $177.0 million for the same period last fiscal year. The increase in revenues during the three months ended September 30, 2020 primarily related to increased 3D Sensing product shipments addressing the consumer market, and growth within the telecom and datacom markets.

Operating income for the three months ended September 30, 2020 increased 91% to $50.7 million, compared to operating income of $26.5 million for the same period last fiscal year. The increase of 700 basis points in operating income during the three-month period compared to the same period last fiscal year was primarily driven by strong growth within our higher margin products, including indium phosphide components for transceivers and datacenters and the 5G optical access infrastructure.

Liquidity and Capital Resources

Historically, our primary sources of cash have been from operations, long-term borrowing, and advance funding from customers. Other sources of cash include proceeds from the issuance of equity, proceeds received from the exercises of stock options, and sale of equity investments and businesses. Our historic uses of cash have been for capital expenditures, investment in research and development, business acquisitions, payments of principal and interest on outstanding debt obligations,

25

payments of debt issuance costs to obtain financing and payments in satisfaction of employees’ minimum tax obligations. Supplemental information pertaining to our sources and uses of cash for the periods indicated is presented as follows:

Sources (uses) of Cash (millions):

	Three Months Ended September 30,
	2020		2019
Net cash provided by operating activities	$	134.3	$	(25.6)
Net proceeds from equity issuance	883.9		—
Proceeds from exercises of stock options	1.1		3.0
Proceeds on long-term borrowings	—		1,570.0
Debt issuance costs	—		(63.5)

Payments in satisfaction of employees' minimum tax obligations	(5.6)		(9.4)
Effect of exchange rate changes on cash and cash equivalents and other items	2.2		(4.7)

Net cash provided by operating activities:

Net cash provided by operating activities was $134.3 million during the current three-month period compared to $25.6 million of cash used by operating activities during the same period last fiscal year.  The increase in cash flows provided by operating activities during the three months ended September 30, 2020 compared to the same period last fiscal year was primarily driven by additional net earnings in the quarter ended September 30, 2020 compared to the quarter ended September 30, 2019 of $65.8 million, of which $32.2 was attributable to Finisar, and incremental transaction costs in the three months ended September 30, 2019 related to the Finisar acquisition. Additional drivers of increased cash flow from operations over the prior year included incremental amortization and depreciation, along with improved working capital during the current quarter.

Net cash used in investing activities:

Net cash used in investing activities was $69.9 million for the three months ended September 30, 2020, compared to net cash used of $1,064.2 million for the same period last fiscal year. Net cash used in investing activities during the current period primarily included $36.1 million for net cash paid for the acquisition of Ascatron AB and $33.8 million of capital expenditures to increase capacity to meet the growing demand for the Company’s product portfolio. Net cash used in investing activities from the three-month period ended September 30, 2019 was primarily used to fund the Finisar acquisition.

Net cash provided by financing activities:

Net cash provided by financing activities was $123.0 million for the three months ended September 30, 2020, compared to net cash provided by financing activities of $1,326.6 million for the same period last fiscal year. Net cash provided by financing activities was primarily impacted by $883.9 million of net proceeds from the Company's equity issuance in July 2020, offset by cash used to repay borrowings of $755.1 million.

Senior Credit Facilities

The Company currently has Senior Credit Facilities with Bank of America, N.A., as Administrative Agent, Swing Line Lender and an L/C Issuer, and the other lenders party thereto.

The Credit Agreement provides for senior secured financing of $2.425 billion in the aggregate, consisting of

(i)Aggregate principal amount of $1,255 million for a five-year senior secured first-lien term A loan facility (the “Term A Facility”),

(ii)Aggregate principal amount of $720 million for a seven-year senior secured term B loan facility (the “Term B Facility” and together with the Term A Facility, the “Term Loan Facilities”), which was repaid in full during the quarter ended September 30, 2020, and

(iii)Aggregate principal amount of $450 million for a five-year senior secured first-lien revolving credit facility (the “Revolving Credit Facility” and together with the Term Loan Facilities, the “Senior Credit Facilities”).

26

The Credit Agreement also provides for a letter of credit sub-facility not to exceed $25.0 million and a swing loan sub-facility initially not to exceed $20.0 million.

The Term B Facility was repaid in full by the Company subsequent to the public offerings that closed on July 7, 2020. Additional information regarding the underwritten public offering is set forth in Note 12.

Additional information regarding the Senior Credit Facilities is set forth in Note 9. Debt to our unaudited condensed consolidated financial statements in Part 1, Item 1 of this Quarterly Report on Form 10-Q.

Item 3.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

MARKET RISKS

The Company is exposed to market risks arising from adverse changes in foreign currency exchange rates. In the normal course of business, the Company uses a variety of techniques and derivative financial instruments as part of its overall risk management strategy, which is primarily focused on its exposure in relation to the Japanese Yen, Chinese Renminbi, Swiss Franc, Euro, and the Malaysian Ringgit. No significant changes have occurred in the techniques and instruments used.

Interest Rate Risks

As of September 30, 2020, the Company’s total borrowings include variable rate borrowings, which exposes the Company to changes in interest rates. On November 24, 2019, the Company entered into an interest rate swap contract to limit the exposure of its variable interest rate debt by effectively converting it to fixed interest rate debt.  If the Company had not effectively hedged its variable rate debt, a change in the interest rate of 100 basis points on these variable rate borrowings would have resulted in additional interest expense of $3.4 million for the three months ended September 30, 2020.

Item 4.    CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

The Company’s management evaluated, with the participation of the Company’s Chief Executive Officer and Chief Financial Officer and Treasurer, the effectiveness of the Company’s disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) as of the end of the period covered by this Quarterly Report on Form 10-Q. The Company’s disclosure controls were designed to provide reasonable assurance that information required to be disclosed in reports that we file or submit under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission. It should be noted that the design of any system of controls is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote. However, the controls have been designed to provide reasonable assurance of achieving the controls’ stated goals. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective as of the end of the period covered by this Quarterly Report on Form 10-Q.

Changes in Internal Control over Financial Reporting

No changes in the Company’s internal control over financial reporting (as such term is defined in Rule 13a-15(f) under the Exchange Act) were implemented during the Company’s most recently completed fiscal quarter that have materially affected or are reasonably likely to materially affect the Company’s internal control over financial reporting.

27

Part II – Other Information

Item 1.    LEGAL PROCEEDINGS

The Company and its subsidiaries are involved from time to time in various claims, lawsuits, and regulatory proceedings incidental to its business. The resolution of each of these matters is subject to various uncertainties, and it is possible that these matters may be resolved unfavorably to the Company. Management believes, after consulting with legal counsel, that the ultimate liabilities, if any, resulting from these legal and regulatory proceedings will not materially affect the Company’s financial condition, liquidity or results of operations.

Item 1A.    RISK FACTORS

In addition to the other information set forth in this Quarterly Report on Form 10-Q, carefully consider the factors discussed in Part I, “Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended June 30, 2020, any of which could materially affect our business, financial condition or future results. Those risk factors are not the only risks facing the Company. Additional risks and uncertainties not currently known or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results.

Item 2.    ISSUER PURCHASES OF EQUITY SECURITIES

In August 2014, the Company’s Board of Directors authorized the Company to purchase up to $50 million of its Common Stock through a share repurchase program (the “Program”) that calls for shares to be purchased in the open market or in private transactions from time to time. The Program has no expiration and may be suspended or discontinued at any time.  Shares purchased by the Company are retained as treasury stock and available for general corporate purposes. As of September 30, 2020, the Company has cumulatively purchased 1,416,587 shares of its Common Stock pursuant to the Program for approximately $22.3 million.

Finisar Acquisition

Finisar AcquisitionOn September 24, 2019 (the “Closing Date”), the Company completed its acquisition of Finisar, a global technology leader for subsystems and components for fiber optic communications.

The purchase price allocation set forth herein is final. The Company utilized widely accepted income-based, market-based, and cost-based valuation approaches to perform the purchase price allocation. Income-based valuation approaches included the use of the discounted cash flow and relief-from-royalty methods for certain acquired intangible assets.

Our final allocation of the purchase price of Finisar, based on the estimated fair value of the assets acquired and liabilities assumed as of the Closing Date, is as follows (in $000):

Other Acquisitions and Investments

Acquisition of Ascatron AB

On August 20, 2020, the Company acquired all of the outstanding shares of Ascatron AB, located in Sweden. The acquisition will add essential elements to the Company's vertically integrated silicon carbide technology platform. Purchase price consideration totaled $36.7 million.

Due to the timing of the acquisition, the Company is in the process of measuring the fair value of assets acquired and liabilities assumed, including tangible and intangible assets and related deferred income taxes. The following table presents a

preliminary allocation of the purchase price of the assets acquired and liabilities assumed at the date of acquisition ($000):

Assets
Developed technology	$	20,000
Goodwill	18,922
Other assets	2,511
Total assets acquired	$	41,433
Liabilities
Non-interest bearing liabilities	$	(203)
Deferred tax liability	(4,526)
Total liabilities assumed	(4,729)
Net assets acquired	$	36,704

The goodwill is recorded in the Compound Semiconductor segment and is attributed to the workforce acquired as part of the transaction. The goodwill is non-deductible for income tax purposes. Transaction expenses related to the acquisition totaled $1.9 million for three months ended September 30, 2020 and is included in Selling, General and Administrative expenses in the Condensed Consolidated Statement of Earnings.

The amount of revenues and net earnings from the acquisition included in the Company’s Condensed Consolidated Statement of Earnings for the three months ended September 30, 2020 were insignificant.

Purchase of Equity Investment in INNOViON Corporation

As of September 30, 2020, the Company holds a 93.8% equity investment in INNOViON Corporation ("Innovion"), a leader in ion implantation technology for silicon and compound semiconductor devices, which was acquired in November 2017 for $51.5 million. The Company’s pro-rata share of earnings from this investment for the three months ended September 30, 2020 and 2019 was insignificant.

This investment is accounted for under the equity method of accounting. The following table summarizes the Company's equity in this nonconsolidated investment:

Location	Interest Type	Ownership % as of September 30, 2020	Equity as of September 30, 2020 ($000)
USA	Equity Investment	93.8%	$	59,539

Innovion was determined to be a variable interest entity because the Company had an overall 93.8% economic position in Innovion, comprising a significant portion of its capitalization, but had only a 25% voting interest. The Company’s right to receive rewards and obligation to absorb expected losses was disproportionate to its voting interest. The Company was not the primary beneficiary because it did not have the power to direct the activities of the equity investment that most significantly impacts its economic performance. Certain business decisions, including decisions with respect to operating budgets, material capital expenditures, indebtedness, significant acquisitions or dispositions, and strategic decisions, require the approval of owners holding a majority percentage in Innovion.  The Company previously accounted for its interest as an equity method investment as the Company had the ability to exercise significant influence over operating and financial policies of Innovion.

As of September 30, 2020 and June 30, 2020, the Company’s maximum financial statement exposure related to Innovion was approximately $59.5 million and $58.8 million, respectively, which is included in Investments on the Condensed Consolidated Balance Sheets.

On August 10, 2020, the Company entered into an agreement to acquire all the outstanding interests of Innovion. The Company acquired the remaining outstanding interests of Innovion on October 1, 2020.

Senior Credit Facilities

The Company currently has Senior Credit Facilities with Bank of America, N.A., as Administrative Agent, Swing Line Lender and an L/C Issuer, and the other lenders party thereto.

The Credit Agreement provides for senior secured financing of $2.425 billion in the aggregate, consisting of

(i)Aggregate principal amount of $1,255 million for a five-year senior secured first-lien term A loan facility (the “Term A Facility”),

(ii)Aggregate principal amount of $720 million for a seven-year senior secured term B loan facility (the “Term B Facility” and together with the Term A Facility, the “Term Loan Facilities”), which was repaid in full during the quarter ended September 30, 2020, and

(iii)Aggregate principal amount of $450 million for a five-year senior secured first-lien revolving credit facility (the “Revolving Credit Facility” and together with the Term Loan Facilities, the “Senior Credit Facilities”).

The Credit Agreement also provides for a letter of credit sub-facility not to exceed $25.0 million and a swing loan sub-facility initially not to exceed $20.0 million.

The Term B Facility was repaid in full by the Company subsequent to the public offerings that closed on July 7, 2020. In conjunction with the repayment, the Company paid $0.6 million in associated interest and expensed $24.7 million of debt issuance costs related to the Term B Facility.

The Company is obligated to repay the outstanding principal amount of the Term A Facility in quarterly installments equal to 1.25% of the initial aggregate principal amount of the Term A Facility, with the remaining outstanding balance due and payable on the fifth anniversary of the Closing Date.

The Company’s obligations under the Senior Credit Facilities are guaranteed by each of the Company’s existing or future direct and indirect domestic subsidiaries, including Finisar and its domestic subsidiaries (collectively, the “Guarantors”). Borrowings under the Senior Credit Facilities are collateralized by a first priority lien in substantially all of the assets of the Company and the Guarantors, except that no real property is collateral under the Senior Credit Facilities.

All amounts outstanding under the Senior Credit Facilities will become due and payable 120 days prior to the maturity of the Company’s currently outstanding 0.25% Convertible Senior Notes due 2022 (the “II-VI Notes”) if (i) the II-VI Notes remain outstanding, and (ii) the Company has insufficient cash and borrowing availability to repay the principal amount of the II-VI Notes.

Amounts outstanding under the Senior Credit Facilities will bear interest at a rate per annum equal to an applicable margin over a eurocurrency rate or an applicable margin over a base rate determined by reference to the highest of (a) the federal funds rate plus 0.50%, (b) Bank of America, N.A.’s prime rate and (c) a eurocurrency rate plus 1.00%, in each case as calculated in accordance with the terms of the Credit Agreement. The applicable interest rate would increase under certain circumstances relating to events of default.  The Company has entered into an interest rate swap contract to hedge its exposure to interest rate risk on its variable rate borrowings under the Senior Credit Facilities.  Refer to Note 16 for further information regarding this interest rate swap.

The Credit Agreement contains customary affirmative and negative covenants with respect to the Senior Credit Facilities, including limitations with respect to liens, investments, indebtedness, dividends, mergers and acquisitions, dispositions of assets and transactions with affiliates. The Company will be obligated to maintain a consolidated interest coverage ratio (as calculated in accordance with the terms of the Credit Agreement) as of the end of each fiscal quarter of not less than 3.00:1.00. The Company will be obligated to maintain a consolidated total net leverage ratio (as calculated in accordance with the terms of the Credit Agreement) of not greater than (i) 5.00 to 1.00 for the first four fiscal quarters after the Closing Date, commencing with the first full fiscal quarter after the Closing Date, (ii) 4.50 to 1.00 for the fifth fiscal quarter through and including the eighth fiscal quarter after the Closing Date, and (iii) 4.00 to 1.00 for each subsequent fiscal quarter. As of September 30, 2020, the Company was in compliance with all financial covenants under the Credit Agreement.

0.50% Finisar Convertible Notes

Finisar’s outstanding 0.50% Convertible Senior Notes due 2036 (the “Finisar Notes”) may be redeemed at any time on or after December 22, 2021 in whole or in part at the option of the Company at a redemption price equal to one hundred percent (100)% of the principal amount of such Finisar Notes plus accrued and unpaid interest. Each holder of Finisar Notes also may require Finisar to repurchase all or any portion of such holder’s outstanding Finisar Notes for cash on December 15, 2021, December 15, 2026 and December 15, 2031 at a repurchase price equal to one hundred percent (100%) of the principal amount of such Finisar Notes plus accrued and unpaid interest. The Finisar Notes will mature on December 15, 2036. Interest on the Finisar Notes accrues at 0.50% per annum, paid semi-annually, in arrears, on June 15 and December 15 of each year.

In connection with the acquisition of Finisar, the Company, Finisar and the trustee entered into a First Supplemental Indenture, dated as of September 24, 2019 (the “First Supplemental Indenture”). The First Supplemental Indenture supplements the base indenture (as supplemented, the “Finisar Indenture”), which governs the Finisar Notes. Pursuant to the terms of the First Supplemental Indenture, the Company has fully and unconditionally guaranteed, on a senior unsecured basis, the due and punctual payment and performance of all obligations of Finisar to the holders of the Finisar Notes. The First Supplemental Indenture also provides that the right of holders of Finisar Notes to convert Finisar Notes into cash and/or shares of Finisar’s common stock, is changed to a right to convert Finisar Notes into cash and/or shares of the Company’s common stock, subject to the terms of the Finisar Indenture.

Under the terms of the Finisar Indenture, the consummation and effectiveness of the Merger on the Closing Date constituted a Fundamental Change (as defined in the Finisar Indenture) and a Make-Whole Fundamental Change (as defined in the Finisar Indenture). Accordingly, in accordance with the terms of the Finisar Indenture, each holder of Finisar Notes had the right to (i) convert its Finisar Notes into cash and/or shares of Company Common Stock, at Finisar’s option, or (ii) require that Finisar repurchase such holder’s Finisar Notes for an amount in cash equal to one hundred percent (100)% of the principal amount of such Finisar Notes plus accrued and unpaid interest.

Holders of approximately $560.1 million in aggregate principal amount of Finisar Notes exercised the repurchase right. The Company repurchased those Finisar Notes on October 23, 2019 for an aggregate consideration of approximately $561.1 million in cash, including accrued interest. No holders of Finisar Notes exercised the related conversion right. The Company borrowed $561.0 million under a delayed draw on its Term Loan A to fund the payment to the holders of Finisar Notes that exercised the repurchase right. As of September 30, 2020, approximately $14.9 million in aggregate principal amount of Finisar Notes remain outstanding.

0.25% Convertible Senior Notes

In August 2017, the Company issued and sold $345 million aggregate principal amount of the II-VI Notes in a private placement to qualified institutional buyers within the meaning of Rule 144A under the Securities Act of 1933, as amended.

As a result of our cash conversion option, the Company separately accounted for the value of the embedded conversion option as a debt discount. The value of the embedded conversion option was determined based on the estimated fair value of the debt without the conversion feature, which was determined using an expected present value technique (income approach) to estimate the fair value of similar nonconvertible debt; the debt discount is being amortized as additional non-cash interest expense over the term of the II-VI Notes using the effective interest method.

The equity component is not remeasured as long as it continues to meet the conditions for equity classification. The initial conversion rate is 21.25 shares of common stock per $1,000 principal amount of II-VI Notes, which is equivalent to an initial conversion price of $47.06 per share of common stock. Throughout the term of the II-VI Notes, the conversion rate may be adjusted upon the occurrence of certain events. The if-converted value of the II-VI Notes amounted to $297.4 million as of September 30, 2020 and $346.2 million as of June 30, 2020 (based on the Company’s closing stock price on the last trading day of the fiscal periods then ended). As of September 30, 2020, the II-VI Notes are not yet convertible based upon the II-VI Notes’ conversion features.  Holders of the II-VI Notes will not receive any cash payment representing accrued and unpaid interest upon conversion of a II-VI Note. Accrued but unpaid interest will be deemed to be paid in full upon conversion rather than cancelled, extinguished or forfeited.

The following tables set forth total interest expense recognized related to the II-VI Notes for the three months ended September 30, 2020 and September 30, 2019 ($000):

	Three Months Ended September 30, 2020		Three Months Ended September 30, 2019
0.25% contractual coupon	$	220	$	220
Amortization of debt discount and debt issuance costs including initial purchaser discount	3,407		3,255
Interest expense	$	3,627	$	3,475

The effective interest rate on the liability component for both periods presented was 4.5%. The unamortized discount amounted to $23.8 million as of September 30, 2020 and is being amortized over three years.

Aggregate Availability

The Company had aggregate availability of $399.6 million under its line of credit as of September 30, 2020.

Weighted Average Interest Rate

The weighted average interest rate of total borrowings was 1.8% and 1.9% for the three months ended September 30, 2020 and 2019, respectively.

Income Taxes

Income Taxes

The Company’s year-to-date effective income tax rate at September 30, 2020 was 22.3% compared to a benefit of 14.8% for the same period in 2019. The variations between the Company’s effective tax rate and the U.S. statutory rate of 21% were primarily due to the impact of the U.S. enacted tax legislation partially offset by research and development incentives in certain jurisdictions and foreign tax credits. 

U.S. GAAP prescribes the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements which includes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. As of September 30, 2020 and June 30, 2020, the Company’s gross unrecognized income tax benefit, excluding interest and penalties, was $40.5 million and $42.8 million, respectively. The Company has classified $7.4 million of uncertain tax positions as current income tax liabilities and the remaining uncertain tax positions of $33.1 million as noncurrent income tax liabilities, as the amounts are not expected to be paid within one year. If recognized, $37.7 million of the gross unrecognized tax benefits at September 30, 2020 would impact the effective tax rate. The Company recognizes interest and penalties related to uncertain tax positions in the income tax provision in the Condensed Consolidated Statements of Earnings (Loss). The amount of accrued interest and penalties included in the gross unrecognized income tax benefit was $3.6 million and $3.8 million at September 30, 2020 and June 30, 2020, respectively. Fiscal years 2017 to 2021 remain open to examination by the U.S. Internal Revenue Service, fiscal years 2015 to 2021 remain open to examination by certain state jurisdictions, and fiscal years 2009 to 2019 remain open to examination by certain foreign taxing jurisdictions.  The Company is currently under examination for certain subsidiary companies in the Philippines for the year 2017; Germany for the years 2012 through 2015; Australia for the years 2011 through 2014; and India for the year 2016. The Company believes its income tax reserves for these tax matters are adequate.

Leases

Leases

On July 1, 2019, the Company adopted Topic 842, Leases, using the modified retrospective transition approach. We determine if an arrangement is a lease at inception and classify it as either finance or operating. The Company's portfolio of leases contains certain real estate, equipment and vehicle leases.

The Company’s lease liabilities are recognized based on the present value of the remaining fixed lease payments, over the lease term, using a discount rate of similarly secured borrowings available to the Company. For the purpose of lease liability measurement, we consider only payments that are fixed and determinable at the time of commencement. Any variable payments that depend on an index or rate are expensed as incurred. We account for non-lease components, such as common area maintenance, as a component of the lease, and include it in the initial measurement of our lease assets and corresponding liabilities. The Company’s lease terms and conditions may include options to extend or terminate. An option is recognized when it is reasonably certain that we will exercise that option.

The Company’s lease assets also include any lease payments made and exclude any lease incentives received prior to commencement. Our lease assets are tested for impairment in the same manner as long-lived assets used in operations.

The following table presents lease costs, which include short-term leases, lease term, and discount rates ($000):

Leases

Leases

On July 1, 2019, the Company adopted Topic 842, Leases, using the modified retrospective transition approach. We determine if an arrangement is a lease at inception and classify it as either finance or operating. The Company's portfolio of leases contains certain real estate, equipment and vehicle leases.

The Company’s lease liabilities are recognized based on the present value of the remaining fixed lease payments, over the lease term, using a discount rate of similarly secured borrowings available to the Company. For the purpose of lease liability measurement, we consider only payments that are fixed and determinable at the time of commencement. Any variable payments that depend on an index or rate are expensed as incurred. We account for non-lease components, such as common area maintenance, as a component of the lease, and include it in the initial measurement of our lease assets and corresponding liabilities. The Company’s lease terms and conditions may include options to extend or terminate. An option is recognized when it is reasonably certain that we will exercise that option.

The Company’s lease assets also include any lease payments made and exclude any lease incentives received prior to commencement. Our lease assets are tested for impairment in the same manner as long-lived assets used in operations.

The following table presents lease costs, which include short-term leases, lease term, and discount rates ($000):

Mandatory Convertible Preferred Stock

On July 2, 2020, II-VI announced the pricing of an underwritten public offering of 2,000,000 shares of 6.00% Series A Mandatory Convertible Preferred, no par value per share (“Mandatory Convertible Preferred Stock”), resulting in gross proceeds to II-VI from the offering of $400 million, before deducting the underwriting discounts and commissions and offering expenses payable by the Company (the "Preferred Stock Offering"). In addition, the underwriters had a 30-day option to purchase up to an additional 300,000 shares of Series A Mandatory Convertible Preferred Stock at the applicable public offering price, less underwriting discounts and commissions and solely to cover over-allotments with respect to the preferred stock offering. On July 2, 2020, the underwriters exercised the option in full, raising an additional approximately $60 million in gross proceeds. On July 7, 2020, the Company closed the Preferred Stock Offering, including the issuance and sale of 2.3 million shares of Mandatory Convertible Preferred Stock.

Upon conversion on the mandatory conversion date, as determined in accordance with the terms of the Mandatory Convertible Preferred Stock, each outstanding share of the Mandatory Convertible Preferred Stock, unless previously converted, will automatically convert into a number of shares of the Company's common stock equal to not more than 4.6512 shares of common stock and not less than 3.8760 shares of common stock (the “Minimum Conversion Rate”), depending on the applicable market value of the common stock, determined in accordance with the terms of the Mandatory Convertible Preferred Stock and subject to certain anti-dilution adjustments.

Other than in the event of one of certain fundamental changes, a holder of Mandatory Convertible Preferred Stock may, at any time prior to July 1, 2023, elect to convert such holder’s shares of Mandatory Convertible Preferred Stock, in whole or in part (but in no event less than one share of Mandatory Convertible Preferred Stock), at the Minimum Conversion Rate per share of Mandatory Convertible Preferred Stock, subject to certain anti-dilution adjustments.

If one of certain fundamental changes occurs on or prior to July 1, 2023, holders of the Mandatory Convertible Preferred Stock will have the right to convert their shares of Mandatory Convertible Preferred Stock, in whole or in part (but in no event less than one share of the Mandatory Convertible Preferred Stock), into shares of the Company's common stock at the conversion rate determined in accordance with the terms of the Mandatory Convertible Preferred Stock during the period beginning on, and including, the effective date of such change and ending on, and including, the date that is 20 calendar days after the effective date of such fundamental change (or, if later, the fundamental date that is 20 calendar days after holders receive notice of such fundamental change, but in no event later than July 1, 2023). Holders who convert their shares of the Mandatory Convertible Preferred Stock during that period will also receive a dividend make-whole amount and, to the extent there is any, the accumulated dividend amount, in each case as calculated in accordance with the terms of the Mandatory Convertible Preferred Stock.

The Company recognized $6.4 million of accrued preferred stock dividends, which were presented as other accrued liabilities on our Condensed Consolidated Balance Sheet as of September 30, 2020.

Common Stock Offering

On July 2, 2020, II-VI announced the pricing of an underwritten public offering of 9,302,235 shares of its common stock at a public offering price of $43.00 per share, resulting in gross proceeds to II-VI from the offering of approximately $400 million, before deducting the underwriting discounts and commissions and offering expenses payable by II-VI (the “Common Stock Offering”). In addition, the underwriters had a 30-day option to purchase up to an additional 1,395,335 shares of its common stock at the applicable public offering price, less underwriting discounts and commissions. On July 2, 2020, the underwriters exercised the option in full, raising an additional approximately $60 million in gross proceeds. On July 7, 2020, the Company closed the Common Stock Offering, including the issuance and sale of approximately 10.7 million shares of Common Stock.

Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per ShareBasic earnings (loss) per common share is computed by dividing net earnings (loss) available to common shareholders by the weighted-average number of shares of common stock outstanding during the period.

Diluted earnings (loss) per common share is computed by dividing the diluted earnings (loss) available to common shareholders by the weighted-average number of shares of common stock and potentially dilutive shares of common stock outstanding during the period. The dilutive effect of equity awards is calculated based on the average stock price for each fiscal period, using the treasury stock method. Diluted shares outstanding include the dilutive effect of the potential shares of the Company's common stock issuable from stock options, performance and restricted shares.

Potentially dilutive shares whose effect would have been antidilutive are excluded from the computation of diluted earnings (loss) per common share. For the three months ended September 30, 2020, diluted earnings (loss) per share excluded the potentially dilutive effect of the potential shares of the Company's common stock issuable upon conversion of outstanding convertible debt as well as the potentially dilutive effect of the Mandatory Convertible Preferred Stock (under the If-Converted method), as their effects were anti-dilutive.

The following is a reconciliation of the numerators and denominators of the basic and diluted earnings (loss) per share computations for the periods presented ($000):

Segment Reporting [Abstract]

Segment Reporting

Segment Reporting

The Company reports its business segments using the “management approach” model for segment reporting. This means that the Company determines its reportable business segments based on the way the chief operating decision maker organizes business segments within the Company for making operating decisions and assessing financial performance.

The Company reports its financial results in the following two segments: (i) Compound Semiconductors, and (ii) Photonic Solutions, and the Company’s chief operating decision maker receives and reviews financial information based on these segments.  The Company evaluates business segment performance based upon segment operating income, which is defined as earnings before income taxes, interest and other income or expense. The segments are managed separately due to the market, production requirements and facilities unique to each segment.

Ascatron is presented within the Compound Semiconductors segment since the date of acquisition.

The accounting policies are consistent across each segment. To the extent possible, the Company’s corporate expenses and assets are allocated to the segments. Unallocated and Other includes eliminating inter-segment sales and transfers, the results of Finisar since the acquisition date through September 30, 2019, and transaction costs related to the Finisar transaction.

Share-Based Compensation

Share-based Payment Arrangement [Abstract]

Share-Based Compensation

Share-Based CompensationThe Company’s Board of Directors adopted the II-VI Incorporated 2018 Omnibus Incentive Plan (the “Plan”), which was approved by the Company’s shareholders. The Plan provides for the grant of performance-based cash incentive awards, non-qualified stock options, stock appreciation rights, restricted share awards, restricted share units, deferred share awards, performance share awards and performance share units to employees, officers and directors of the Company. The maximum number of shares of the Company’s Common Stock authorized for issuance under the Plan is limited to 3,550,000 shares of Common Stock, not including any remaining shares forfeited under the predecessor plans that may be rolled into the Plan. The Company records share-based compensation expense for these awards in accordance with U.S. GAAP, which requires the

recognition of grant-date fair value of share-based compensation in net earnings (loss) and over the requisite service period of the individual grantees, which generally equals the vesting period. The Company accounts for cash-based stock appreciation rights, cash-based restricted share unit awards and cash-based performance share unit awards as liability awards, in accordance with applicable accounting standards.  

Upon consummation of the acquisition of Finisar, the Company assumed approximately 6.6 million restricted stock units previously granted by Finisar under the Amended and Restated Finisar Corporation 2005 Stock Incentive Plan (each an “Assumed RSU”), and the Company also assumed the unused capacity under the Finisar 2005 Plan.

Fair Value of Financial Instruments

Business Combinations [Abstract]

Fair Value of Financial Instruments

Fair Value of Financial Instruments

The FASB defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous markets for the asset and liability in an orderly transaction between market participants at the measurement date. The Company estimates fair value of its financial instruments utilizing an established three-level hierarchy in accordance with U.S. GAAP. The hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date as follows:

•Level 1 –Valuation is based upon unadjusted quoted prices for identical assets or liabilities in active markets.

•Level 2 –Valuation is based upon quoted prices for similar assets and liabilities in active markets, or other inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instruments.

•Level 3 –Valuation is based upon other unobservable inputs that are significant to the fair value measurements.

The classification of fair value measurements within the hierarchy is based upon the lowest level of input that is significant to the measurement.

The Company entered into an interest rate swap with a notional amount of $1,075 million to limit the exposure to its variable interest rate debt by effectively converting it to a fixed interest rate. The Company receives payments based on the one-month LIBOR and makes payments based on a fixed rate of 1.52%. The Company receives payments with a floor of 0.00%. The interest rate swap agreement has an effective date of November 24, 2019, with an expiration date of September 24, 2024. The initial notional amount of the interest rate swap is scheduled to decrease to $825 million in June 2022 and will remain at that amount through the expiration date. The Company designated this instrument as a cash flow hedge and deemed the hedge relationship effective at inception of the contract. The fair value of the interest rate swap of $44.6 million is recognized in the Condensed Consolidated Balance Sheet within other liabilities as of September 30, 2020. Changes in fair value are recorded within accumulated other comprehensive income (loss) on the Condensed Consolidated Balance Sheet and reclassified into the Condensed Consolidated Statement of Earnings (Loss) as interest expense in the period in which the underlying transaction affects earnings.  Cash flows from hedging activities are reported in the Condensed Consolidated Statements of Cash Flows in the same classification as the hedged item, generally as a component of cash flows from operations. The fair value of the interest rate swap is determined using widely accepted valuation techniques and reflects the contractual terms of the interest rate swap including the period to maturity, and while there are no quoted prices in active markets, it uses observable market-based inputs, including interest rate curves. The fair value analysis also considers a credit valuation adjustment to reflect nonperformance risk of both the Company and the single counterparty. The interest rate swap is classified as a Level 2 item within the fair value hierarchy.

The Company estimated the fair value of the II-VI Notes and Finisar Notes based on quoted market prices as of the last trading day prior to September 30, 2020; however, the II-VI Notes and Finisar Notes have only a limited trading volume and as such this fair value estimate is not necessarily the value at which the II-VI Notes and Finisar Notes could be retired or transferred.

The Company concluded that this fair value measurement should be categorized within Level 2. The carrying value of the II-VI Notes and Finisar Notes is net of unamortized discount and issuance costs. See Note 9. Debt for details on the Company’s debt facilities.

The fair value and carrying value of the II-VI Notes and Finisar Notes were as follows at September 30, 2020 ($000):

	Fair Value		Carrying Value
II-VI Notes	$	390,619	$	317,719
Finisar Notes	13,734		14,888

The fair values of cash and cash equivalents are considered Level 1 among the fair value hierarchy and approximate fair value because of the short-term maturity of those instruments. The Company’s borrowings including its lease obligations, excluding the 0.25% Convertible Notes and the 0.50% Finisar convertible notes are considered Level 2 among the fair value hierarchy and their principal amounts approximate fair value.
